Abstract
INTRODUCTION Opportunistic infections (OIs) are more common and severe among people with suppressed immunity like those living with HIV/AIDS (PLWH). This study aimed to assess the prevalence of OIs and associated factors among PLWH attending antiretroviral therapy (ART) clinics in the Gedeo zone, Southern Ethiopia. METHODS A facility based retrospective cohort study was conducted from April to June 2018 among PLWH attending ART clinics in Gedeo zone, Ethiopia from November 2016 - November 2017. A simple random sampling method was used to select the both paper based and electronic study participants' charts. Adjusted odds ratios were calculated using multivariable logistic regression analysis for variables statistically significant at 95% confidence interval under bivariable logistic regression analysis, and significance was declared at P < 0.05. RESULTS a total of 266 PLWH attended the selected ART clinics of Gedeo zone during the one year period were participated in the current study. The majority 104(39.1%) were within the age group 30-39, 106(60.2%) male, 184(69.2%) married, and 167(62.9%) urban residents. The study revealed the prevalence of OIs was 113(42.5%) with oral candidiasis 28(24.5%) the most prevalent followed by pulmonary tuberculosis 22(19.5%) and herpes zoster 15(13.4%). Further, study participants with ambulatory [AOR = 2.40(95% CI: 1.14, 5.03)], and bedridden [AOR = 3.27(95% CI:1.64, 6.52)] working functional status; with lower CD4 count: less than 200cells/mm3 [AOR = 9.14(95% CI: 2.75, 30.39)], 200-350cells/mm3 [AOR = 9.45(95% CI: 2.70,33.06)], 351-500cells/mm3 [AOR = 5.76(95% CI: 1.71, 19.39)]; being poor in ART adherence level [AOR = 10.05(95% CI: 4.31,23.46)]; being in stage III/IV WHO clinical stage of HIV/AIDS [AOR = 2.72(95% CI: 1.42, 5.20)]; and being chewing khat [AOR = 2.84(95% CI: 1.21, 6.65)] were found positively predicting the occurrence of OIs. CONCLUSION This study speckled a high prevalence of OIs with several predicting factors. Therefore, the study acmes there should be interventional means which tackles the higher prevalence of OIs with focus to the predicting factors like lower CD4 count level, less/bedridden working functional status, poor ART adherence level, advanced stage of HIV/AIDS stage and chewing khat.

[PMID: 39066418 PMCID: PMC11281599 DOI: 10.3390/vaccines12070780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Revised: 07/08/2024] [Accepted: 07/15/2024] [Indexed: 07/28/2024] Open
Abstract
Vaccine-preventable diseases (VPDs) pose a serious public health concern for people living with HIV (PLH). PLH experience a delayed and weakened response to many vaccines available, compared to the general population. Lower seroconversion rates, along with a decreased efficacy and durability of vaccines, increases the susceptibility of PLH to VPDs. Vaccination guidelines specifically targeting this population have been modified to overcome these challenges. However, vaccine uptake remains suboptimal due to multiple barriers, highlighting the need for further studies and the additional implementation of public health measures specifically tailored to PLH.

Abstract
OBJECTIVE Youth living with HIV (YLHIV) in the southern United States experience poor outcomes across the HIV care continuum and are at high-risk for virologic failure. This study used a qualitative, community-engaged approach to inform the development of a tailored mobile Health (mHealth) tool for YLHIV in South Carolina (SC). METHODS Semistructured qualitative interviews were conducted with YLHIV in SC (n = 16) and their HIV care providers (n = 15). Focus group discussions (FGDs) were also conducted with HIV-focused community-based organization staff (n = 23). Interviews and FGDs queried desired components for a future mHealth tool tailored for YLHIV. Data were analyzed using a team-based rapid qualitative approach. RESULTS Across informants, key themes emerged related to medical management of HIV, including a desire for connections with medical providers, appointment and medication reminders, and accurate HIV information. In addition, informants voiced a desire for mental health resources to be integrated into the app. Connection with HIV-positive peers also emerged as a key desire from youth informants. In terms of app design, informants emphasized the need for strict privacy practices, a youth-friendly design, compensation for use, and integration with existing healthcare systems. CONCLUSIONS mHealth interventions developed for YLHIV should meet the mental health and social needs of YLHIV in addition to their medical needs. In addition, the highly stigmatized nature of HIV requires careful consideration when designing digital tools-youth want their privacy prioritized, but also express strong desire for social support to help cope with the isolation and stigma of this chronic health condition.

Abstract
Central nervous system infections have been suggested as a possible cause for neurodegenerative diseases, particularly sporadic cases. They trigger neuroinflammation which is considered integrally involved in neurodegenerative processes. In this review, we will look at data linking a variety of viral, bacterial, fungal, and protozoan infections to Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis and unspecified dementia. This narrative review aims to bring together a broad range of data currently supporting the involvement of central nervous system infections in the development of neurodegenerative diseases. The idea that no single pathogen or pathogen group is responsible for neurodegenerative diseases will be discussed. Instead, we suggest that a wide range of susceptibility factors may make individuals differentially vulnerable to different infectious pathogens and subsequent pathologies.

Abstract
Cardiac abnormalities were identified early in the epidemic of AIDS, predating the isolation and characterization of the etiologic agent, HIV. Several decades later, the causation and pathogenesis of cardiovascular disease (CVD) linked to HIV infection continue to be the focus of intense speculation. Before the widespread use of antiretroviral therapy, HIV-associated CVD was primarily characterized by HIV-associated cardiomyopathy linked to profound immunodeficiency. With increasing antiretroviral therapy use, viral load suppression, and establishment of immune competency, the effects of HIV on the cardiovascular system are more subtle. Yet, people living with HIV still face an increased incidence of cardiovascular pathology. Advances in cardiac imaging modalities and immunology have deepened our understanding of the pathogenesis of HIV-associated CVD. This review provides an overview of the pathogenesis of HIV-associated CVD integrating data from imaging and immunologic studies with particular relevance to the HIV population originating from high-endemic regions, such as sub-Saharan Africa. The review highlights key evidence gaps in the field and suggests future directions for research to better understand the complex HIV-CVD interactions.

Central Carbon Metabolism in Candida albicans Biofilms Is Altered by Dimethyl Sulfoxide. J Fungi (Basel) 2024; 10:337. [PMID: 38786692 PMCID: PMC11121877 DOI: 10.3390/jof10050337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Revised: 03/25/2024] [Accepted: 04/04/2024] [Indexed: 05/25/2024] Open
Abstract
The effect of dimethyl sulfoxide (DMSO) on fungal metabolism has not been well studied. This study aimed to evaluate, by metabolomics, the impact of DMSO on the central carbon metabolism of Candida albicans. Biofilms of C. albicans SC5314 were grown on paper discs, using minimum mineral (MM) medium, in a dynamic continuous flow system. The two experimental conditions were control and 0.03% DMSO (v/v). After 72 h of incubation (37 °C), the biofilms were collected and the metabolites were extracted. The extracted metabolites were subjected to gas chromatography-mass spectrometry (GC/MS). The experiment was conducted using five replicates on three independent occasions. The GC/MS analysis identified 88 compounds. Among the 88 compounds, the levels of 27 compounds were markedly different between the two groups. The DMSO group exhibited enhanced levels of putrescine and glutathione and decreased levels of methionine and lysine. Additionally, the DMSO group exhibited alterations in 13 metabolic pathways involved in primary and secondary cellular metabolism. Among the 13 altered pathways, seven were downregulated and six were upregulated in the DMSO group. These results indicated a differential intracellular metabolic profile between the untreated and DMSO-treated biofilms. Hence, DMSO was demonstrated to affect the metabolic pathways of C. albicans. These results suggest that DMSO may influence the results of laboratory tests when it is used as a solvent. Hence, the use of DMSO as a solvent must be carefully considered in drug research, as the effect of the researched drugs may not be reliably translated into clinical practice.

Frequency of fungal pathogens in autopsy studies of people who died with HIV in Africa: a scoping review. Clin Microbiol Infect 2024; 30:592-600. [PMID: 38145865 PMCID: PMC11103628 DOI: 10.1016/j.cmi.2023.12.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 12/11/2023] [Accepted: 12/16/2023] [Indexed: 12/27/2023]
Abstract
BACKGROUND Fungal infections are common in HIV-infected individuals and significantly contribute to mortality. However, a substantial number of cases are undiagnosed before death. OBJECTIVE To determine the frequency of fungal pathogens in autopsy studies of people who died with HIV in Africa. METHODS We conducted a scoping review of autopsy studies conducted in Africa. DATA SOURCES PubMed, Scopus, Web of Science, Embase, Google Scholar, and African Journal Online. STUDY ELIGIBILITY CRITERIA The review encompasses studies published from inception to September 2023, and no language restrictions were imposed during the search process. We included studies that reported histopathological or microbiological evidence for the diagnosis of fungal infections and other pathogens. DATA SYNTHESIS Data were summarized using descriptive statistics and no meta-analysis was performed. RESULTS We examined 30 articles reporting studies conducted between 1991 and 2019, encompassing a total of 13 066 HIV-infected decedents across ten African countries. In five studies, the autopsy type was not specified. Among those studies with specified autopsy types, 20 involved complete diagnostic autopsies, whereas 5 were categorized as partial or minimally invasive autopsies. There were 2333 pathogens identified, with 946 (40.5%) being mycobacteria, 856 (36.7%) fungal, 231 (3.8%) viral, 208 (8.9%) parasitic, and 92 (3.9%) bacterial. Of the 856 fungal pathogens identified, 654 (28.0%) were Cryptococcus species, 167 (7.2%) Pneumocystis jirovecii, 16 (0.69%) Histoplasma species, 15 (0.64%) Aspergillus species, and 4 (0.17%) Candida species. Other major non-fungal pathogens identified were cytomegalovirus 172 (7.37%) and Toxoplasma gondii 173 (7.42%). CONCLUSIONS Invasive fungal infections occur in over one-third of people who succumb to HIV in Africa. In addition to cryptococcosis and Pneumocystis jirovecii pneumonia, integrating other priority fungal pathogen detection and management strategies into the broader framework of HIV care in Africa is recommended. This involves increasing awareness regarding the impact of fungal infections in advanced HIV disease and strengthening diagnostic and treatment capacity.

Abstract
BACKGROUND We performed a systematic review to generate evidence on the association between cumulative human immunodeficiency virus (HIV) viraemia and health outcomes. METHODS Quantitative studies reporting on HIV cumulative viraemia (CV) and its association with health outcomes among people living with HIV (PLHIV) on antiretroviral treatment (ART) were included. We searched MEDLINE via PubMed, Embase, Scopus and Web of Science and conference abstracts from 1 January 2008 to 1 August 2022. RESULTS The systematic review included 26 studies. The association between CV and mortality depended on the study population, methods used to calculate CV and its level. Higher CV was not consistently associated with greater risk of acquire immunodeficiency syndrome-defining clinical conditions. However, four studies present a strong relationship between CV and cardiovascular disease. The risk was not confirmed in relation of increased hazards of stroke. Studies that assessed the effect of CV on the risk of cancer reported a positive association between CV and malignancy, although the effect may differ for different types of cancer. CONCLUSIONS CV is associated with adverse health outcomes in PLHIV on ART, especially at higher levels. However, its role in clinical and programmatic monitoring and management of PLHIV on ART is yet to be established.

Abstract
Optic neuritis is a rare presentation of vitamin B12 deficiency. We describe a 33-year-old female patient living with HIV presenting with progressive loss of vision for 1 week. She had a history of severe peripheral neuropathy that was managed with vitamin B12-containing tablets approximately three years before presenting with progressive loss of vision. On examination, she had no perception of light in the left eye and no perception of hand motion in the right eye. The fundus in her left eye had mild blurring of disc margins. Results from tests done showed a haemoglobin of 12.9g/dl, MCV 101fl, a serum vitamin B12 of 78pmol/l, and cytomegalovirus (CMV) test showed no active disease. She was diagnosed with optic neuritis and started on 30 mg tablets of prednisolone for 1 week with slight improvement. She was then started on vitamin B12 injections 1 mg daily for 10 days and thereafter, monthly for 6 months. She reported gradual improvement and regained her sight after 5 months treatment of with Vitamin B12 injections. Ophthalmic manifestations of vitamin B12 deficiency are not common and may present without haematological signs therefore, a high index of suspicion is required for early diagnosis and management of vitamin B12 deficiency.

Ann Afr Med 2024; 23:125-131. [PMID: 39028159 PMCID: PMC11210728 DOI: 10.4103/aam.aam_42_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 08/14/2023] [Accepted: 08/23/2023] [Indexed: 07/20/2024] Open
Abstract
BACKGROUND INFORMATION Over 1.6 million Nigerians have succumbed to the ravaging scourge of the acquired immunodeficiency syndrome (AIDS) epidemic since its discovery. Viral suppression (VS) then becomes a critical cost-effective human immunodeficiency virus (HIV) prevention strategy. We assessed the prevalence and predictors of VS. MATERIALS AND METHODS This retrospective case file review was conducted among adults (aged ≥18 years) living with HIV/AIDS who accessed care at a tertiary health facility in Northwestern Nigeria between January and December 2021. RESULTS One thousand one hundred and twenty HIV/AIDS-eligible patients accessed care during the study. Their age ranged between 20 and 70 years with a mean of 43.83 ± 10.83 (95% confidence interval [CI]: 43.19-44.46). The patients were mostly female (728; 65.0), residing in urban areas (680; 60.7%), self-employed (440; 39.3%), married (712; 63.6%), receiving antiretroviral therapy (ART) for at most 14 years (916; 81.8%), on first-line ART regimen (812; 72.5%), in HIV clinical stage 1 (964; 86.1%), and with a baseline CD4 count of 199 cells/µl (453; 40.4%). The prevalence of VS of 64.3% (720/1120) was recorded in the study. The predictors of VS were disclosure of HIV status (odds ratio [OR] =2.4; 95% CI = 1.503-3.832), absence of opportunistic infections (OR = 2.6; 95% CI = 1.242-5.406), receiving ART for 15-29 years (OR = 2.1; 95% CI = 1.398-3.292), first-line ART regimen (OR = 3.7; 95% CI = 2.618-5.115), and adequate adherence (OR = 4.7; 95% CI = 3.324-6.766). CONCLUSION VS was suboptimal among the study cohort with adequate adherence being its strongest predictor.

Abstract
OBJECTIVES To determine the incidence of opportunistic infections (OIs) and the predictive factors for the development of OIs after antiretroviral therapy (ART) initiation among treatment-naïve patients with HIV infection. RESULTS Of 401 HIV-infected patients, 38 (9.5%) HIV-infected patients developed OIs after initiating ART, with an incidence rate of 25.6/1000 person-years. The median time (IQR) from ART initiation to OI occurrence was 26.5 (14-73) days. In multivariate Cox proportional hazard regression, body mass index ≤18.5 kg/m2 (adjusted hazard ratio [aHR] 2.28, 95% confidence interval [CI] 1.18-4.42, P = .015), symptoms at presentation (aHR 13.59, 95% CI 3.24-56.9, P < .001), serum glutamate-pyruvate transaminase >55 U/L (aHR 2.09, 95% CI 1.06-4.15, P = .035), and initiation of a dolutegravir-based regimen (aHR 4.39, 95% CI 1.54-12.48, P = .006) were significantly associated with OIs after ART initiation. CONCLUSION OIs after ART initiation are common. Malnutrition, symptomatic presentation, abnormal liver enzymes, and DTG-based regimens are predictors of OI occurrence after ART initiation. Physicians must monitor and appropriately treat OIs after ART initiation.

Abstract
PURPOSE OF REVIEW We aim to review the neurological complications of HIV and the social, cultural, and economic inequalities that contribute to disparities in neuroHIV care. RECENT FINDINGS Disparities in diagnostics and care of patients with neurological infections and non-infectious conditions associated with HIV in both high-income and low-to-middle-income countries (LMIC) are common. The COVID-19 pandemic has exacerbated these disparities. Factors, such as HIV-related stigma, may deter people from accessing HIV treatment. First-line recommended treatments for neurological infections are not available in many LMICs, leading to inadequate treatment and exposure to agents with more harmful side effect profiles. Access-related factors, such as lack of transportation, lack of health insurance, and inadequate telehealth access, may increase the risk of HIV-related neurological complications. Further research is needed to increase awareness of neurological complications among providers and PWH, and regional guidelines should be considered to better address these complications.

The effect of the Universal Test and Treat policy uptake on CD4 count testing and incidence of opportunistic infections among people living with HIV infection in Cameroon: a retrospective analysis of routine data. DIALOGUES IN HEALTH 2023; 2:100120. [PMID: 38515498 PMCID: PMC10954022 DOI: 10.1016/j.dialog.2023.100120] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 02/05/2023] [Accepted: 02/23/2023] [Indexed: 03/23/2024]
Abstract
Background Cameroon adopted and started implementing in 2016, the 'universal test and treat' (UTT) guidelines to fast-track progress towards the 95-95-95 ambitious targets to end the HIV epidemic. UTT has shown inconsistent results elsewhere and has not yet been assessed in Cameroon. We aimed to evaluate the effectiveness of this novel approach on the quality of care and health outcomes of people living with HIV (PLHIV). Methods A retrospective cohort design was conducted at The Nkongsamba Regional Hospital, using routine clinical service delivery data to measure uptake levels of UTT and CD4 testing, and to compare the incidence of opportunistic infections (OI) between PLHIV initiated on ART based on the "Universal Test and Treat" strategy and those initiated on ART based on the standard deferred approach between 2002 and 2020. Kaplan Meier plots and log-rank tests were used to compare OI events between the pre-UTT and post-UTT eras. The Cox regression model was used to screen for factors independently associated with the risk of acquisition of OI. Results The uptake of UTT ranged from 39.1% to 92.8% while baseline CD4 count testing reduced drastically from 89.4% to 0.4% between 2016 to 2020 respectively. The median delay in ART initiation declined significantly from 21 days (IQR: 9 - 113) in the pre-UTT era to the same day of diagnosis (IQR: 0 - 2) in the UTT era (p < 0.001). The incidence of all OI events reported was over five times higher during the UTT era than in the pre-UTT era [aHR = 5.55 (95% CI: 3.18 - 9.69), p < 0.001]. Conclusion The UTT policy has been effectively rolled out and has contributed to improved access to rapid and immediate ART initiation, but a higher incidence of OIs was observed with a rollback of baseline CD4 testing. We advocate for a return to routine baseline CD4 measurement to identify PLHIV who should benefit from interventions to prevent OIs for optimal outcomes under the UTT approach.

HIV Infection and 90-Day Stroke Outcomes in Uganda: A Prospective Observational Cohort Study. Neurol Clin Pract 2023; 13:e200198. [PMID: 38495078 PMCID: PMC10942001 DOI: 10.1212/cpj.0000000000200198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 09/21/2023] [Indexed: 03/19/2024]
Abstract
Background and Objectives Little is known about the impact of HIV infection on the clinical presentation and outcomes after stroke in the modern antiretroviral therapy (ART) era. We aimed to compare stroke characteristics and outcomes between persons with HIV (PWH) and without HIV (PWOH) presenting with stroke in Uganda. Methods We conducted a matched cohort study at Mulago National Referral Hospital and Mbarara Regional Referral Hospital between January 2018 and November 2020. We enrolled consecutive PWH presenting with CT-confirmed acute or subacute stroke (symptom onset ≤14 days) and matched them by sex and stroke type to 2 consecutive available PWOH admitted to the same hospital. We obtained baseline clinical data and followed participants for 90 days from the day of clinical presentation. We compared stroke severity (defined by the NIH stroke scale [NIHSS]) and 90-day all-cause mortality and morbidity (using the modified Rankin Scale [mRS]) by HIV serostatus with and without adjustment for confounders. Results We enrolled 105 PWH and 157 PWOH with stroke. PWH were younger (mean [SD] age 49 [14] vs 59 [16] years, p < 0.001), and nearly 80% (82/105) were on ART for a median of 5 years and a median CD4 count of 214 cells/uL (interquartile range 140, 337). Compared with PWOH, PWH presented with a 3-point lower median NIHSS (16 vs 19, p = 0.011), a 20% lower proportion of all-cause mortality at 90 days (p = 0.001), and had less disability at 90 days (median mRS 4 vs 5, p = 0.004). Age and NIHSS-adjusted odds ratio of 90-day all-cause mortality in PWH compared with PWOH was 0.45 (95% CI 0.22-0.96, p = 0.037). Discussion In the modern ART era, PWH with acute stroke in Uganda present with modest stroke and are significantly less likely to die within 90 days than PWOH. This potentially reflects the protective effects of ART, enhanced health care access, and their younger age at stroke presentation.

Abstract
Biofilm deposition on indwelling medical devices and implanted biomaterials is frequently attributed to the prevalence of resistant infections in humans. Further, the nature of persistent infections is widely believed to have a biofilm etiology. In this study, the wettability of commercially available indwelling medical devices was explored for the first time, and its effect on the formation of biofilm was determined in vitro. Surprisingly, all tested indwelling devices were found to be hydrophilic, with surface water contact angles ranging from 60° to 75°. First, we established a thriving Candida albicans biofilm growth at 24 hours. in YEPD at 30°C and 37°C plus serum in vitro at Cyclic olefin copolymer (COC) modified surface, which was subsequently confirmed via scanning electron microscopy, while their cellular metabolic function was assessed using the XTT cell viability assay. Surfaces with patterned wettability show that a contact angle of 110° (hydrophobic) inhibits C. albicans planktonic and biofilm formation completely compared to robust growth at a contact angle of 40° (hydrophilic). This finding may provide a novel antimicrobial strategy to prevent biofilm growth and antimicrobial resistance on indwelling devices and prosthetic implants. Overall, this study provides valuable insights into the surface characteristics of medical devices and their potential impact on biofilm formation, leading to the development of improved approaches to control and prevent microbial biofilms and re-infections.

Survival and prognostic factors of progressive multifocal leukoencephalopathy in people living with HIV in modern ART era. Front Cell Infect Microbiol 2023; 13:1208155. [PMID: 38029233 PMCID: PMC10663249 DOI: 10.3389/fcimb.2023.1208155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 10/24/2023] [Indexed: 12/01/2023] Open
Abstract
Background The incidence of progressive multifocal leukoencephalopathy (PML) in people living with HIV (PLWH) is 2%-4%. Currently, there is no effective therapeutic strategy for the treatment of PML in PLWH, resulting in a mortality of up to 50%. This study aimed to identify risk factors of death and prognostic markers in people living with HIV with PML. Methods A retrospective cohort study of AIDS-related PML individuals was conducted from January 1, 2015, to October 1, 2022, in Shanghai, China. PLWH who were diagnosed with PML for the first time were included. Kaplan-Meier curve and Cox regression were used to analyze the survival and its predictors. Levels of inflammatory markers and immune checkpoint inhibitors in blood and cerebrospinal fluid (CSF) were measured in the prestored samples using bead-based multiplex assay Indolamine 2,3-dioxygenase was determined using ELISA. Results Twenty of 71 subjects had initiated antiretroviral therapy (ART) before PML onset and no patients discontinued ART during this period. In total, 34 patients (47.9%) had opportunistic infections (OIs), the median CD4+ T cell count was 73.0 (33.0-149.0) cells/μL. The estimated probability of survival at six months was 78% (95% confidential intervals [CIs]:0.63-0.85). OIs, low CD4+ T cell count were associated with lower estimated six-month survival (hazard ratio 8.01, 95% CIs: 1.80-35.00, P=0.006 and 5.01, 95% CIs:1.57-16.03, p=0.007). Indolamine 2,3-dioxygenase activity in CSF of non-survivors group were higher than survivors group (p<0.05). Conclusions The survival rate of AIDS-related PML in the modern ART era was higher than the survival rate a decade ago. Low CD4+T cell count, OIs, were all associated with death of individuals with AIDS-related PML. The role of IDO in AIDS-related PML warrant further investigation.

Abstract
Herpes zoster is typically a blister rash involving a single skin group, caused by the reactivation of primary varicella zoster virus infection. Disseminated herpes zoster refers to the presence of more than 20 small blisters outside the primary or adjacent skin, which is rare and usually occurs in individuals with weakened immune function. This case described a patient diagnosed with disseminated herpes zoster, with a decrease in CD4 count (379 cells/mm3) and certain skin lesions. He was subsequently screened positive for HIV. Also, we summarized other studies on the CD4 value of HIV patients with herpes zoster. Overall, for herpes zoster patients with decreased CD4 levels and certain skin manifestations, such as diffuse, ulcerative, or pustular lesions, clinicians should be aware of HIV infection.

Abstract
BACKGROUND Cardiovascular diseases (CVDs) have become an important cause of ill health and death among people living with HIV and/or AIDS (PLHIV) in the antiretroviral therapy (ART) era. There is scarce data on the burden of hypertension (HTN) and risk factors for CVDs among PLHIV in developing countries, including Tanzania during the ART era. OBJECTIVE(S) To determine the prevalence of HTN and risk factors for CVDs among ART naïve PLHIV initiating ART. METHODS We analysed baseline data of 430 clinical trial participants on the effect of low-dose aspirin on HIV disease progression among HIV-infected individuals initiating ART. HTN was the outcome CVD. Traditional risk factors for CVDs studied were age, alcohol consumption, cigarette smoking, individual and family history of CVDs, diabetes mellitus (DM), obesity/overweight, and dyslipidaemia. A generalized linear model (robust Poisson regression) was used to determine the predictors for HTN. RESULTS The median (IQR) age was 37 (28, 45) years. Females were the majority contributing 64.9% of all participants. The prevalence of HTN was 24.8%. The most prevalent risk factors for CVDs were dyslipidaemia (88.3%), alcohol consumption (49.3%), and overweight or obesity (29.1%). Being overweight or obese predicted the occurrence of HTN, aPR 1.60 (95% CI 1.16-2.21) while WHO HIV clinical stage 3 was protective against HTN, aPR 0.42(95% CI 0.18-0.97). CONCLUSION The prevalence of HTN and traditional risk factors for CVDs in the treatment naïve PLHIV initiating ART are significant. Identifying these risk factors and managing them at the time of ART initiation may lower future CVDs among PLHIV.

[PMID: 36984440 PMCID: PMC10056804 DOI: 10.3390/medicina59030440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 02/20/2023] [Accepted: 02/21/2023] [Indexed: 02/25/2023]
Abstract
Background and Objectives: Human immunodeficiency virus infection and the acquired immunodeficiency syndrome (HIV/AIDS) pandemic are unquestionably the most serious public crisis of our time. Identifying, preventing, and treating HIV-associated comorbidities remains a challenge that must be addressed even in the era of antiretroviral therapy. Materials and Methods: In this study, we aimed to characterize the aspects of newly diagnosed patients with HIV/AIDS, during 2021-2022 in Northeastern Romania. We reviewed the frequency and associated comorbidities of these patients in correspondence with national and global results. Results: Our study found that of all newly diagnosed HIV cases (167 cases-74 cases in 2021 and 98 cases in 2022), 49.70% were diagnosed with HIV infection and 50.30% had AIDS. Based on sex correlated with the CD4+ T-lymphocyte level, the most affected were males, with a lower CD4+ T-lymphocyte level overall. The average HIV viral load was 944,689.55 copies/mL. Half of males had an abnormal ALT or AST (39.53% and 49.61%); as for the females, less than a quarter had an increased value of ALT or AST, respectively (18% and 26%). The most frequent co-infections were as follows: oral candidiasis (34.73% of patients), hepatitis B (17.37% of patients), and SARS-CoV-2 infection (8.38%), followed by hepatitis C (6.39%), tuberculosis (TB), syphilis, toxoplasmosis, Cryptococcus, Cytomegalovirus infections. Males were more affected than females, with a higher percentage of co-infections. The prescribed antiretroviral treatment focused on a single-pill regimen (79.04%) to ensure adherence, effectiveness, and safety. Therefore, 20.96% had been prescribed a regimen according to their comorbidities. Conclusions: Our study found a concerning rise in the incidence of HIV in 2022 compared to that in 2021 in Northeastern Romania, because of the rise in post-SARS-CoV-2 pandemic addressability. Advanced immunodeficiency and the burden of opportunistic infections characterize newly diagnosed HIV patients. The physicians should keep in mind that these patients may have more than one clinical condition at presentation.

Abstract
BACKGROUND Anaemia affects one in four adults in South Africa, with a higher prevalence in persons with HIV and tuberculosis. The aim of this study is to characterise the causes of anaemia in primary care and a district hospital setting. METHODS A cross-sectional study design investigated a purposive sample of adult males and non-pregnant females at two community health centres and a hospital casualty and outpatients. Fingerpick blood haemoglobin was measured with HemoCueHb201+. Those with moderate and severe anaemia underwent clinical examination and laboratory tests. RESULTS Of 1327 patients screened, median age was 48 years, and 63.5% were female. Of 471 (35.5%) with moderate and severe anaemia on HemoCue, 55.2% had HIV, 16.6% tuberculosis, 5.9% chronic kidney disease, 2.6% cancer, and 1.3% heart failure. Laboratory testing confirmed 227 (48.2%) with moderate and 111 (23.6%) with severe anaemia, of whom 72.3% had anaemia of inflammation, 26.5% iron-deficiency anaemia, 6.1% folate deficiency, and 2.5% vitamin B12 deficiency. Overall, 57.5% had two or more causes of anaemia. Multivariate modelling showed that patients with severe anaemia were three times more likely to have tuberculosis (OR = 3.1, 95% CI = 1.5-6.5; p-value = 0.002). Microcytosis was present in 40.5% with iron deficiency, macrocytosis in 22.2% with folate deficiency, and 33.3% with vitamin B12 deficiency. The sensitivities of the reticulocyte haemoglobin content and % hypochromic red blood cells in diagnosing iron deficiency were 34.7% and 29.7%, respectively. CONCLUSIONS HIV, iron deficiency, and tuberculosis were the most prevalent causes of moderate and severe anaemia. The majority had multiple causes. Iron, folate, and vitamin B12 deficiencies should be identified by biochemical testing rather than by red cell volume.

Abstract
South Africa adopts intensive livestock farming, embracing the employment of huge quantities of antibiotics to meet the increased demand for meat. Therefore, bacteria occurring in the animal products and manure might develop antibiotic resistance, a scenario which threatens public health. The study investigated the occurrence of Gram-negative bacteria from eighteen pooled samples withdrawn from a single-stage steel biodigester co-digesting pig manure (75%) and pine wood saw dust (25%). The viable counts for each bacterium were determined using the spread plate technique. The bacterial isolates were characterised based on cultural, morphological and biochemical characteristics, using the Analytical Profile Index 20 e test kit. In addition, isolates were characterised based on susceptibility to 14 conventional antibiotics via the disc diffusion method. The MAR index was calculated for each bacterial isolate. The bacterial counts ranged from 104 to 106 cfu/mL, indicating manure as a potential source of contamination. Overall, 159 bacterial isolates were recovered, which displayed diverse susceptibility patterns with marked sensitivity to amoxicillin (100% E. coli), streptomycin (96.15% for Yersinia spp.; 93.33% for Salmonella spp.) and 75% Campylobacter spp. to nitrofurantoin. Varying resistance rates were equally observed, but a common resistance was demonstrated to erythromycin (100% of Salmonella and Yersinia spp.), 90.63% of E. coli and 78.57% of Campylobacter spp. A total of 91.19% of the bacterial isolates had a MAR index > 0.2, represented by 94 MAR phenotypes. The findings revealed multidrug resistance in bacteria from the piggery source, suggesting they can contribute immensely to the spread of multidrug resistance; thus, it serves as a pointer to the need for the enforcement of regulatory antibiotic use in piggery farms. Therefore, to curb the level of multidrug resistance, the piggery farm should implement control measures in the study area.

Abstract
Background Reliable data on the burden of opportunistic infections (OIs) after the initiation of antiretroviral therapy (ART) is critical for planning health services and reducing OI-related morbidity and mortality. Nevertheless, there has been no nationally representative information on the prevalence of OIs in our country. Therefore, we have undertaken this comprehensive systematic review and meta-analysis to estimate the pooled prevalence, and identify factors associated with the development of OIs in Human Immunodeficiency Virus (HIV)-infected adults receiving ART in Ethiopia. Methods Articles were searched in international electronic databases. A standardized Microsoft Excel spreadsheet and STATA software version 16 were used for data extraction and analysis, respectively. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist was used to write this report. The random-effect meta-analysis model was used to estimate the pooled effect. The statistical heterogeneity of the meta-analysis was checked. Subgroup and sensitivity analyses were also performed. Publication bias was examined in funnel plots and the nonparametric rank correlation test of Begg and the regression-based test of Egger. Association was expressed through a pooled odds ratio (OR) with a 95% Confidence Interval (CI). Results A total of 12 studies with 6,163 study participants were included. The pooled prevalence of OIs was 43.97% [95% CI (38.59, 49.34)]. Poor adherence to ART [OR, 5.90, 95% CI (3.05, 11.40)], under nutrition [OR, 3.70, 95% CI (2.01, 6.80)], CD4 T lymphocyte count <200 cells /μL [OR, 3.23 95% CI (2.06, 5.07)], and advanced World Health Organization (WHO) HIV clinical stages [OR, 4.84 95% CI (1.83, 12.82)] were determinants of OIs. Conclusion The pooled prevalence of OIs among adults taking ART is high. Poor adherence to ART, under nutrition, a CD4 T lymphocyte count <200 cells /μL, and advanced WHO HIV clinical stages were factors associated with the development of OIs.

Abstract
BACKGROUND Information about burden, characteristics, predictors, and outcomes of advanced human immunodeficiency virus disease (AHD) is scarce in rural settings of sub-Saharan Africa. Human immunodeficiency virus (HIV) infections and associated deaths remain high despite specific guidelines issued by the World Health Organization (WHO). METHODS Burden of AHD and 6-month death/loss to follow-up (LTFU) were described among 2498 antiretroviral therapy (ART)-naive nonpregnant people with HIV (PWH) aged >15 years enrolled in the Kilombero Ulanga Antiretroviral Cohort in rural Tanzania between 2013 and 2019. Baseline characteristics associated with AHD and predictors of death/LTFU among those with AHD were analyzed using multivariate logistic and Cox regression, respectively. RESULTS Of the PWH, 62.2% had AHD at diagnosis (66.8% before vs 55.7% after national uptake of WHO "test and treat" guidelines in 2016). At baseline, older age, male sex, lower body mass index, elevated aminotransferase aspartate levels, severe anemia, tachycardia, decreased glomerular filtration rate, clinical complaints, impaired functional status, and enrollment into care before 2018 were independently associated with AHD. Among people with AHD, incidence of mortality, and LTFU were 16 and 34 per 100 person-years, respectively. WHO clinical stage 3 or 4, CD4 counts <100 cells/µL, severe anemia, tachypnea, and liver disease were associated with death/LTFU. CONCLUSIONS More than 50% of PWH enrolled in our cohort after test and treat implementation still had AHD at diagnosis. Increasing HIV testing and uptake and implementation of the WHO-specific guidelines on AHD for prevention, diagnosis, treatment of opportunistic infections, and reducing the risks of LTFU are urgently needed to reduce morbidity and mortality.

Woldegeorgis BZ, Diro CW, Yohannes B, Kerbo AA, Asgedom YS. Incidence and predictors of opportunistic infections in adolescents and adults after the initiation of antiretroviral therapy: A 10-year retrospective cohort study in Ethiopia. Front Public Health 2022; 10:1064859. [PMID: 36589962 PMCID: PMC9797664 DOI: 10.3389/fpubh.2022.1064859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Accepted: 11/23/2022] [Indexed: 12/16/2022] Open
Abstract
Background Opportunistic infections (OIs) are the leading cause of morbidity and mortality in people living with the human immunodeficiency virus (PLHIV). However, there are few robust recent data on the rates of OIs and the risk factors that contribute to their occurrence. Therefore, the current study sought to determine the incidence of OIs and identify predictors among adolescents and adults after the initiation of antiretroviral therapy (ART) at Wolaita Sodo University Comprehensive Specialized Hospital (WSUCSH), Southern Ethiopia. Methods A retrospective cohort study design was employed. The study population was adolescents and adults who initiated ART between 1 January 2012 and 31 December 2021. A simple random sampling technique was used to select 537 participants' records. We reviewed the medical records of the sampled individuals from 1 May 2022 to 15 June 2022. KoboCollect version 2021.2.4 and STATA version 14.0 software were used for data collection and analysis, respectively. We calculated the incidence rate per 100 person-years of observation (PYO) with 95% confidence intervals (CIs) for the occurrence of any OIs. The Weibull regression model was fitted after the goodness-of-fit test for the Cox proportional hazard model was deemed inadequate. An adjusted hazard ratio (AHR) with 95% CI was used to identify a significant predictor of OIs. The statistical significance was made at a 5% significance level. Results A total of 515 participants contributed to 1,829 person-years of risk, of whom 164 (31.84%) exhibited at least one OI. The overall incidence rate of OIs was 8.97 cases (95% CI: 7.69, 10.44) per 100 PYO. The independent predictors of OIs were being female [AHR: 1.65 (95% CI (1.15, 2.36), P = 0.007)], individuals classified as World Health Organization (WHO) HIV clinical stage III [AHR: 1.98 (95% CI (1.12, 3.51), P = 0.019)], individuals who did not take cotrimoxazole preventive therapy (CPT) [AHR: 2.58 (95% CI (1.62, 4.11), P < 0.001)], mild malnutrition [AHR: 1.62 (95% CI (1.06, 2.54), P = 0.035)], and poor adherence to ART [AHR: 4.21 (95% CI (2.39, 7.44), P < 0.001)]. Conclusion The rate of OIs after the initiation of ART was still high. Moreover, being female, not taking CPT, poor adherence to ART, mild malnutrition, and advanced HIV disease at presentation were found to increase the hazards of developing OIs.

Abstract
Background Information on the frequency and clinical features of advanced HIV disease (AHD) in pregnancy and its effects on maternal and perinatal outcomes is limited. The objective of this study was to describe the prevalence and clinical presentation of AHD in pregnancy, and to assess the impact of AHD in maternal and perinatal outcomes in Mozambican pregnant women. Methods This is a prospective and retrospective cohort study including HIV-infected pregnant women who attended the antenatal care (ANC) clinic at the Manhiça District Hospital between 2015 and 2020. Women were followed up for 36 months. Levels of CD4 + cell count were determined to assess AHD immune-suppressive changes. Risk factors for AHD were analyzed and the immune-suppressive changes over time and the effect of AHD on pregnancy outcomes were assessed. Results A total of 2458 HIV-infected pregnant women were enrolled. The prevalence of AHD at first ANC visit was 14.2% (349/2458). Among women with AHD at enrolment, 76.2% (260/341) were on antiretroviral therapy (ART). The proportion of women with AHD increased with age reaching 20.5% in those older than 35 years of age (p < 0.001). Tuberculosis was the only opportunistic infection diagnosed in women with AHD [4.9% (17/349)]. There was a trend for increased CD4 + cell count in women without AHD during the follow up period; however, in women with AHD the CD4 + cell count remained below 200 cells/mm3 (p < 0.001). Forty-two out of 2458 (1.7%) of the women were severely immunosuppressed (CD4 + cell count < 50 cells/mm3). No significant differences were detected between women with and without AHD in the frequency of maternal mortality, preterm birth, low birth weight and neonatal HIV infection. Conclusions After more than two decades of roll out of ART in Mozambique, over 14% and nearly 2% of HIV-infected pregnant women present at first ANC clinic visit with AHD and severe immunosuppression, respectively. Prompt HIV diagnosis in women of childbearing age, effective linkage to HIV care with an optimal ART regimen and close monitoring after ART initiation may contribute to reduce this burden and improve maternal and child survival.

Abstract
Invasive fungal infections are emerging diseases that kill over 1.5 million people per year worldwide. With the increase of immunocompromised populations, the incidence of invasive fungal infections is expected to continue to rise. Vaccines for viral and bacterial infectious diseases have had a transformative impact on human health worldwide. However, no fungal vaccines are currently in clinical use. Recently, interest in fungal vaccines has grown significantly. One Candida vaccine has completed phase 2 clinical trials, and research on vaccines against coccidioidomycosis continues to advance. Additionally, multiple groups have discovered various Cryptococcus mutant strains that promote protective responses to subsequent challenge in mouse models. There has also been progress in antibody-mediated fungal vaccines. In this review, we highlight recent fungal vaccine research progress, outline the wealth of data generated, and summarize current research for both fungal biology and immunology studies relevant to fungal vaccine development. We also review technological advancements in vaccine development and highlight the future prospects of a human vaccine against invasive fungal infections.

Abstract
Background Cryptococcal meningitis (CM) is a leading cause of adult meningitis in countries with a high burden of HIV. It has remained a significant cause of morbidity and mortality in Africa despite the extensive rollout of HIV antiretroviral therapy (ART). This study aimed to systematically synthesize the evidence on the prevalence of CM among people living with HIV (PLWH) and its predictors of mortality among adults who are on induction antifungal therapy in Africa. Methods PubMed/MEDLINE, Embase, and Google Scholar were searched for randomized clinical trials or observational studies published in Africa from 1995 to April 2021. Pooled prevalence of CM among PLWH was calculated using R-studio Version 1.4.1717 software and the data extracted from eligible studies were pooled as percentage with a 95% confidence interval (CI). Predictors of mortality among adults on induction antifungal therapy were synthesized narratively. Results Out of 364 studies identified, 17 eligible articles were included in the analysis. The prevalence of CM among PLWH in Africa was 5.11% (95% CI 2.71-9.43%; participants = 10,813; studies = 9; I 2 = 97%). In the subgroup analysis, the prevalence was 12.9% (95% CI 4.883-30.0; participants = 533; studies = 3; I 2 = 63%) in the years 1995-2010 and 3.18% (95% CI 1.54-6.45; participants = 10,280; studies = 6; I 2 = 98%) in the years 2011-2021, with the prevalence significantly decreased by 51% (p = 0.02). Predictors of mortality were fluconazole monotherapy, focal neurological signs, low Glasgow coma scale, and delayed diagnosis of CM at varied timepoint. Conclusion Prevalence of CM has significantly decreased from 1996-2010 to 2011-2021 among PLWH on induction therapy in Africa. Fluconazole monotherapy, focal neurological symptoms, diastolic blood pressure < 60 mmHg, and concurrent tuberculosis coinfection were significant predictors of mortality at 2- and 10-weeks timepoints. CM remains a major concern among PLWH despite increases in ART coverage. Improved access to effective antifungal therapies is needed in Africa for timely initiation of combination induction therapy and better treatment outcomes of PLWH.

Abstract
Introduction Impairment of the innate immune function may contribute to the increased risk of bacterial and viral infections in people with HIV (PWH). In this study we aimed to investigate the induced innate immune responses in PWH prior to and after initiation of combinational antiretroviral therapy (cART). Furthermore, we aimed to investigate if the induced innate immune responses before initiation of cART were associated with CD4+ T-cell recovery one year after initiating cART. Material and method The induced innate immune response was assessed by the TruCulture® whole blood technique in 32 PWH before cART initiation and after 1, 6 and 12 months. To mimic bacterial and viral infections we used a panel of three stimuli (lipopolysaccharide (LPS), resiquimod (R848), and polyinosinic:polycytidylic acid (Poly I:C)) to stimulate the extracellular Toll-like receptor (TLR) 4 and the intracellular TLR7/8 and TLR3, respectively. The following cytokine responses were analyzed by Luminex 200: Tumor Necrosis Factor (TNF)-α, Interleukin (IL)-1b, IL-6, IL-8, IL-10, IL-12p40, IL17A, Interferon (IFN)-α, and IFN-γ. Results At baseline PWH with nadir CD4+ T-cell count <350 cell/µL had lower levels of LPS-, R848-, and Poly I:C-induced IL-6 and IFN-γ, LPS- and R848-induced TNF-α and IL-12, LPS induced IL-1b, and R848-induced IL-10 than PWH with nadir CD4+ T-cell count >350 cells/µL. The majority (>50%) had induced cytokine concentrations below the reference intervals at baseline which was most pronounced for the LPS- and Poly I:C-induced responses. The induced responses in the whole population improved after 12 months of cART, and more PWH had induced cytokine concentrations within the reference intervals after 12 months. However, the majority of PWH still had LPS-induced INF-α, INF-γ and Poly I:C-induced TNF-α and IL-6 below the reference interval. The induced innate immune responses before cART initiation were not associated with the CD4+ T-cell recovery after 12 months of cART. Conclusion The innate immune response was impaired in PWH, with a more pronounced impairment in PWH with low nadir CD4+ T-cell count. Initiation of cART improved the innate immune response, but compared to the reference intervals, some impairment remained in PWH without viral replication.

Abstract
Objectives: To compare the benefits and risks between Rapid ART and standard/delayed treatment for HIV.Methods: Databases of PubMed, Cochrane Library, Embase and Web of science were searched from the inception to 28 October 2021. Two investigators independently screened studies related to Rapid ART, extracted data, and evaluated the literature quality. The risk of bias was assessed by Cochrane Collaboration Risk of Bias Tool and the statistical software Stata15.0 was used for meta-analysis.Results: Ten eligible studies were included in this meta-analysis, the results showed Rapid ART was superior to standard/delayed treatment in continuing care for at least 8 months (RR = 1.13, 95%CI: 1.03∼1.25, Z = 2.44, p = 0.015), and severe bacterial infection (RR = 0.42, 95%CI: 0.25∼0.70, Z = 3.33, p = 0.001). At 12 months following treatment, there was no statistically significant difference in viral load <100 copies/mL (RR = 1.05, 95%CI: 0.80∼1.39, Z = 0.35, p = 0.726), mortality (RR = 0.77, 95%CI: 0.47∼1.24, Z = 1.09, p = 0.277), or the incidence of adverse events (RR = 0.52, 95%CI: 0.16∼1.76, Z = 1.05, p = 0.294) compared with standard/delayed treatment.Conclusion: In comparison to standard/delayed treatment, rapid ART can reduce the incidence of TB and severe bacterial infections in HIV patients. Our findings suggest that rapid ART should be utilized when clinical conditions and the patient’s physical state allow.Systematic Review Registration: [https://inplasy.com/?s=202210004], identifier [INPLASY202210004].

The implementation of the Kinyoun staining technique in a resource-limited setting is feasible and reveals a high prevalence of intestinal cryptosporidiosis in HIV patients. Int J Infect Dis 2022; 122:130-135. [PMID: 35562040 DOI: 10.1016/j.ijid.2022.05.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 05/04/2022] [Accepted: 05/05/2022] [Indexed: 10/18/2022] Open
Abstract
OBJECTIVES In resource-limited settings, intestinal Cryptosporidia or coccidian infections are common causes of chronic diarrhoea, but usually remain undiagnosed by routine stool investigation. Here, the addition of the Kinyoun staining technique after stool concentration was evaluated as an easy and inexpensive method for diagnosis of intestinal parasitic infection in HIV-infected patients. METHODS This cross-sectional study investigated HIV-infected patients with diarrhoea and randomly selected HIV-infected patients without diarrhoea as controls. Stool samples were examined by wet mount microscopy and Kinyoun staining after stool concentration. Clinical, sociodemographic and behavioural data were collected. Statistical analysis was performed using Chi-squared test and multivariate regression analysis. RESULTS In total, 163 participants were included (62.0% female, mean age 38.2 [SD ±10.7] years). Diarrhoea was present in 52.1% (85/163). The prevalence of intestinal parasites was 18.4% (30/163). Cryptosporidia infections were more frequent among patients with diarrhoea (12.9% [11/85] vs. 1.3% [1/78], p=0.005) and in patients with CD4+ cell count <200 cells/µL (25.9% [7/27] vs. 3.7% [5/136], p=0.001). Risk factors for intestinal parasitic infections were diarrhoea and the habit of regularly eating uncooked food. Kinyoun staining was necessary for detection of cryptosporidiosis. CONCLUSION In our cohort, the prevalence of intestinal parasitic infection was high, especially after additional utilization of Kinyoun staining for detection of Cryptosporidia or intestinal coccidia. Considering its clinical relevance particularly in individuals at risk, the implementation of this technique should be considered in resource-limited settings.

[PMID: 35469324 PMCID: PMC9034843 DOI: 10.2147/hiv.s346182] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Accepted: 03/27/2022] [Indexed: 11/23/2022] Open
Abstract
Background Opportunistic infections are the major causes for morbidity and mortality due to HIV infections. Despite advances in HIV diagnosis and management, the incidence of opportunistic infections remains high. This study aimed to assess the incidence and predictors of opportunistic infections among persons living with HIV/AIDS in Ethiopia. Methods A retrospective follow-up study was conducted on 354 samples of adults living with HIV on antiretroviral therapy at Dessie Comprehensive Specialized Hospital. Simple random sampling technique was used to select study participants. The data collection format was taken from national antiretroviral intake and follow-up forms. Epi-data Version 4.6.1 and STATA Version 16 software were used for data entry and data analysis respectively. The Cox-proportional hazards regression model was fitted. Kaplan-Meier survival curve was used to estimate opportunistic infections-free survival time. Both bi-variable and multivariable Cox-proportional hazard regression analysis were done to identify predictors of opportunistic infections. Results Of the total 354 peoples living with HIV, 114 (32.2%) developed OI, with an incidence rate of 13.5 per 100 person-year (95% CI: 10.8-15.6). Advanced World Health Organization clinical disease stage (IV) (AHR: 2.1 (95% CI: 1.16, 3.8)), being bedridden (AHR: 1.66 (95% CI: 1.04, 2.65)), poor adherence (AHR: 1.7 (95% CI: 1.1-2.63), and low CD4 count (AHR: 1.92 95% CI: 1.14-3.22) were significant predictors of OIs. Conclusion Opportunistic infection among HIV/AIDS continues to be a significant public health concern in Ethiopian health care setting. Our results indicate that the incidence of OI is high. Besides, Stage IV HIV status, being bedridden, low CD4 count and poor adherence independently predicts an increased incidence/decreased survival time of OIs among PLWHIV. Early care-seeking and initiation of HAART and continuous follow-up of patients to take their drug timely are essential to curb the incidence of opportunistic infections and improve overall health. Further research on this area is highly recommended.

Abstract
Knowledge gaps remain in the understanding of HIV disease establishment and progression. Scientists continue to strive in their endeavor to elucidate the precise underlying immunopathogenic mechanisms of HIV-related disease, in order to identify possible preventive and therapeutic targets. A useful tool in the quest to reveal some of the enigmas related to HIV infection and disease is the single-cell sequencing (scRNA-seq) technique. With its proven capacity to elucidate critical processes in cell formation and differentiation, to decipher critical hematopoietic pathways, and to understand the regulatory gene networks that predict immune function, scRNA-seq is further considered to be a potentially useful tool to explore HIV immunopathogenesis. In this article, we provide an overview of single-cell sequencing platforms, before delving into research findings gleaned from the use of single cell sequencing in HIV research, as published in recent literature. Finally, we describe two important avenues of research that we believe should be further investigated using the single-cell sequencing technique.

Abstract
Human immunodeficiency virus (HIV) has been generally considered as a highly adaptive and rapidly evolving virus. It still constitutes a major public health problem all over the world despite an effective outcome in the prevention and reversal of the development and prognosis by using antiretroviral therapy. The salient question lies in the more frequent emergence of a series of comorbidities along with the prolongation of the life, which deeply affects the survival in such group. Venous thromboembolism (VTE) has been recognized to be the third most common cardiovascular condition within people living with HIV (PWH). In terms of its mechanism of action, the occurrence of VTE is quite multifactorial and complex in HIV. Prior exploration concerning the etiology of VTE in PWH identifies general, disease-specific, and miscellaneous factors for explaining its occurrence and development. VTE has constituted an important role in PWH and may increase its all-cause mortality. Therefore, it is quite necessary to understand VTE from the following aspects of epidemiology, pathophysiology, molecular mechanisms, and therapeutic interventions so as to balance the risks and benefits of anticoagulation and optimize corresponding treatment.

Abstract
BACKGROUND Opportunistic infections (OIs) are the leading causes of hospitalization, morbidity, and mortality (accounting for 94.1% of all deaths) in people living with human immunodeficiency virus (PLHIV). Despite evidence suggested that undernutrition significantly increases the risk of OIs in PLHIV, to our knowledge, no study has examined the actual effects of undernutrition on OIs in this population, particularly in low-income countries. Thus, this study examined the effects of undernutrition on OIs in adults living with HIV receiving antiretroviral therapy (ART). METHODS We conducted a retrospective cohort study among 841adults living with HIV receiving ART between June 2014 and June 2020 at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia. Study participants were selected using a simple random sampling technique. Data from participants' medical records were extracted using a project-specific data extraction checklist. The Kaplan Meier survival curve estimated the OIs free survival time. The effects of undernutrition on time to develop OIs was estimated using inverse-probability weighting. Finally, regression coefficients with 95% confidence intervals (95% CIs) were reported, with a statistical significance of p < 0.05. RESULTS Of 841 study participants, 262 (31.2%) developed OIs, and the overall incidence rate was 16.7 (95% CI: 14.8, 18.8) per 100 person-years. The incWidence of OIs in undernourished participants (21/100 person-years, 95% CI: 17.8, 27.4) was higher than well-nourished participants (15.0/100 person-years, 95% CI: 12.9, 17.4). When everyone in the population of interest is well-nourished, average time to develop OIs is estimated as 26.5 (coefficient: 26.5, 95% CI: 20.6, 32.4, p < 0.001) months. When everyone in the population of interest is undernourished, average time to develop OIs is estimated as 17.7 (95% CI: 12.8, 22.6) months. However, when everyone is undernourished, average time to develop OIs decreases by 8.8 (coefficient: -8.8, 95% CI: -16.6, -1.0, p = 0.026) months. Lastly, exposure to undernourishment (intervention) (ratio of average treatment effects to well-nourished potential outcome means in this study was a 32.5% reduction in OIs among adults living with HIV on ART. CONCLUSION We found that undernutrition significantly shortened time to develop OIs in adults living with HIV. This implies that the occurrence of OIs in this vulnerable population can be improved through different cost-effective nutritional interventions, such as routine nutritional assessments and education.

Abstract
INTRODUCTION CD4 testing plays an important role in clinical management and epidemiological surveillance of HIV disease. Rapid, point-of-care (POC) CD4 tests can improve patients' access to CD4 testing, enabling decentralization of HIV services. AREAS COVERED We conducted a profile review of the Visitect®CD4 and the Visitect®CD4 Advanced Disease (Omega Diagnostics, UK) - the two lateral flow, equipment-free POC CD4 tests, which can be used to identify people with HIV who have CD4 of less than 350 and 200 cells/μl, respectively. Using published data from independent studies, we discussed the performance and utility of these tests, highlighting the advantages as well as their limitations. EXPERT OPINION The tests are user-friendly, acceptable to health care workers, and feasible to implement in primary health care settings and can provide reliable results for clinical decision-making. Hands-on training with pictorial instructions for use is needed to enhance test's operator confidence in interpretation of test results. Quality assurance program should be in place to ensure the quality of testing. Development of a next-generation test with a cutoff of 100 cells/μl is recommended to identify patients with advanced immunosuppression for initiation of prophylaxis to reduce HIV-related death. Operational research is also needed to identify cost-effective implementation strategies in real-world settings.

Abstract
Background The efficacy of highly active antiretroviral therapy (HAART) can be estimated by the immunological response and the incidence of opportunistic infections. Objective This study aimed at evaluating the effectiveness of different durations of HAART in terms of immunological response markers (CD4 count and CD4/CD8 ratio) along with disease progression markers (incidence of oral lesions) in Chinese patients with HIV. Methods This single-center, retrospective, and real-world study included patients with HIV, grouped into a treatment group and treatment-naïve group, of which the former was further divided into 6, 12, and 18 months based on the treatment duration. The CD4 and CD8 cell counts were analyzed by the FACSCalibur flow cytometry. Kruskal-Wallis test was applied to determine the outcome of different duration of HAART. Oral examination was carried out according to the WHO type IV examination. Results In 246 patients with HIV, CD4 counts increased significantly post-HAART compared to pre-HAART in all three treatment groups (P<.001), while CD8 count decreased significantly (P<.05) in all three treated groups. A significant association of HAART with the CD4/CD8 ratio was observed (P<.001). A significant increase in CD4 count was observed between 12-months and 18-months treatment groups (P<.05). The occurrence of oral lesions reduced significantly in the treatment group. Conclusion We observed a better response to the HAART regimen with 18-months of duration than 12-months and 6-months therapies and reduction in oral lesions.

Abstract
BACKGROUND Available information on the causes of death among people living with human immunodeficiency virus (PLHIV) in low- and middle-income countries (LMICs) remains scarce. We aimed to provide data on causes of death in PLHIV from two LMICs, Brazil and Mozambique, to assess the impact of clinical misdiagnosis on mortality rates and to evaluate the accuracy of minimally invasive tissue sampling (MITS) in determining the cause of death in PLHIV. METHODS We performed coupled MITS and complete autopsy on 164 deceased PLHIV (18 children, 36 maternal deaths, and 110 adults). HIV antibody levels and HIV RNA viral loads were determined from postmortem serum samples. RESULTS Tuberculosis (22.7%), toxoplasmosis (13.9%), bacterial infections (13.9%), and cryptococcosis (10.9%) were the leading causes of death in adults. In maternal deaths, tuberculosis (13.9%), bacterial infections (13.9%), cryptococcosis (11.1%), and cerebral malaria (8.3%) were the most frequent infections, whereas viral infections, particularly cytomegalovirus (38.9%), bacterial infections (27.8%), pneumocystosis (11.1%), and HIV-associated malignant neoplasms (11.1%) were the leading cause among children. Agreement between the MITS and the complete autopsy was 100% in children, 91% in adults, and 78% in maternal deaths. The MITS correctly identified the microorganism causing death in 89% of cases. CONCLUSIONS Postmortem studies provide highly granular data on the causes of death in PLHIV. The inaccuracy of clinical diagnosis may play a significant role in the high mortality rates observed among PLHIV in LMICs. MITS might be helpful in monitoring the causes of death in PLHIV and in highlighting the gaps in the management of the infections.

Abstract
The koala retrovirus (KoRV) is spreading in the koala population from the north to the south of Australia and is also in the process of endogenization into the koala genome. Virus infection is associated with tumorigenesis and immunodeficiency and is contributing to the decline of the animal population. Antibody production is an excellent marker of retrovirus infection; however, animals carrying endogenous KoRV are tolerant. Therefore, the therapeutic immunization of animals carrying endogenous KoRV seems to be ineffective. Using the recombinant transmembrane (TM) envelope protein of the KoRV, we immunized goats, rats and mice, obtaining in all cases neutralizing antibodies which recognize epitopes in the fusion peptide proximal region (FPPR), and in the membrane-proximal external region (MPER). Immunizing several animal species with the corresponding TM envelope protein of the closely related porcine endogenous retrovirus (PERV), as well as the feline leukemia virus (FeLV), we also induced neutralizing antibodies with similar epitopes. Immunizing with the TM envelope protein in addition to the surface envelope proteins of all three viruses resulted in higher titers of neutralizing antibodies. Immunizing KoRV-negative koalas with our vaccine (which is composed of both envelope proteins) may protect these animals from infection, and these may be the starting points of a virus-free population.

Abstract
BACKGROUND Short-course, rifamycin-based regimens could facilitate scale-up of tuberculosis preventive therapy (TPT), but it is unclear how stringently tuberculosis (TB) disease should be ruled out before TPT use. METHODS We developed a state-transition model of a TPT intervention among two TPT-eligible cohorts: adults newly diagnosed with HIV in South Africa (PWH) and TB household contacts in Pakistan (HHCs). We modeled two TPT regimens-4 months of rifampicin [4R] or 6 months of isoniazid [6H]-comparing each to a reference of no intervention. Before initiating TPT, TB disease was excluded either through symptom-only screening or with additional radiographic screening that could detect subclinical TB but might limit access to the TPT intervention. TPT's potential curative effects on both latent and subclinical TB were modeled, as were both acquisitions of resistance and prevention of drug-resistant disease. Although all eligible individuals received the screening and/or TPT interventions, the modeled TB outcomes comprised only those with latent or subclinical TB that would have progressed to symptomatic disease if untreated. RESULTS When prescribed after only symptom-based TB screening (such that individuals with subclinical TB were included among TPT recipients), 4R averted 45 active (i.e., symptomatic) TB cases (95% uncertainty range 24-79 cases or 40-89% of progressions to active TB) per 1000 PWH [17 (9-29, 43-94%) per 1000 HHCs]; 6H averted 37 (19-66, 52-73%) active TB cases among PWH [13 (7-23, 53-75%) among HHCs]. With this symptom-only screening, for each net rifampicin resistance case added by 4R, 12 (3-102) active TB cases were averted among PWH (37 [9-580] among HHCs); isoniazid-resistant TB was also reduced. Similarly, 6H after symptom-only screening increased isoniazid resistance while reducing overall and rifampicin-resistant active TB. Screening for subclinical TB before TPT eliminated this net increase in resistance to the TPT drug; however, if the screening requirement reduced TPT access by more than 10% (the estimated threshold for 4R among HHCs) to 30% (for 6H among PWH), it was likely to reduce the intervention's overall TB prevention impact. CONCLUSIONS All modeled TPT strategies prevent TB relative to no intervention, and differences between TPT regimens or between screening approaches are small relative to uncertainty in the outcomes of any given strategy. If most TPT-eligible individuals can be screened for subclinical TB, then pairing such screening with rifamycin-based TPT maximizes active TB prevention and does not increase rifampicin resistance. Where subclinical TB cannot be routinely excluded without substantially reducing TPT access, the choice of TPT regimen requires weighing 4R's efficacy advantages (as well as its greater safety and shorter duration that we did not directly model) against the consequences of rifampicin resistance in a small fraction of recipients.

[PMID: 34859509 DOI: 10.1111/jop.13266] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 11/03/2021] [Accepted: 11/25/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Oral thrush, a clinical condition due to an overgrowth of Candida yeasts in the oral cavity, is prominent in patients with immunosuppression. As recent updates on oral thrush in South-East Asian (SEA) countries are lacking, this review aimed to address the epidemiology, clinical features and distribution of Candida species, based on published studies in SEA countries over the last two decades. METHODS Published studies on oral candidiasis (2000-2020) were retrieved from PubMed, Scopus, ISI Web of Science and Google Scholar databases to provide information on the incidence and factors affecting oral thrush cases in SEA countries. RESULTS A total of 22 cross-sectional studies involving 3697 subjects from five SEA countries were reviewed in this study. The most frequently reported population were human immunodeficiency virus (HIV)-infected patients. The overall incidence rates amongst HIV-infected patients ranged from 20.7% to 97.0%, while incidence rates ranging from 0% to 72.7% were recorded for non-HIV-infected populations. Pseudomembranous candidiasis and erythematous candidiasis were the most common clinical presentations of oral thrush lesions. Candida albicans was the most common species identified in SEA studies. As oral thrush assessments were made merely based on clinical diagnosis, culture results were not available for most studies. CONCLUSION This review highlights that most studies reporting on oral candidiasis in SEA countries were based on HIV-positive patients. Data are still lacking on oral candidiasis amongst non-HIV immunocompromised and immunocompetent patients. Increasing awareness on the diagnosis, treatment and consequences of this infection, and improved laboratory methods are essential for the management of oral candidiasis in this region.

Abstract
BACKGROUND Varicella-zoster virus (VZV) infection may induce central nervous system complications in HIV/AIDS patients. However, it is rare to have paraplegia caused by VZV infection but no herpes zoster clinically. Asymptomatic VZV infection in HIV/AIDS patient increased the difficulty of diagnosis. CASE PRESENTATION We reported a 41-year-old male AIDS patient with rare asymptomatic VZV infection-induced paraplegia after his anti-retroviral therapy initiation. MRI of the spinal cord showed the morphology of the thoracic spinal cord was irregular and locally inflated. The patient was confirmed as VZV induced thoracic myelomyelitis by using the cerebrospinal fluid for metagenomic next-generation sequencing (mNGS). CONCLUSIONS mNGS may contribute to disease diagnosis for asymptomatic VZV infection-induced myelitis.

Prevalence of and Factors Associated with Reoccurrence of Opportunistic Infections Among Adult HIV/AIDS Patients Attending the ART Clinic at Public Health Facilities in Arba Minch Town, Southern Ethiopia. HIV AIDS-RESEARCH AND PALLIATIVE CARE 2021; 13:867-876. [PMID: 34512035 PMCID: PMC8427687 DOI: 10.2147/hiv.s328362] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 08/23/2021] [Indexed: 11/23/2022]
Abstract
Background Opportunistic infections (OIs) in human immunodeficiency virus (HIV)-positive individuals are infections that are more frequent or more severe than normal because of HIV-mediated immunosuppression. When these OIs occur in acquired immune deficiency syndrome (AIDS) patients in the form of relapse or reinfection, they are said to be a reoccurrence of OI. This study will try to identify gaps in addressing the burden in the study area. Methods This cross-sectional study was conducted among 450 HIV/AIDS patients with previous OIs attending a public health facility in Arba Minch Town, Southern Ethiopia. This study was conducted from 5 April 2020 to 20 April 2020. Computer-generated simple random sampling was used to select the study participants. Analysis was performed using SPSS version 25 statistical software. Bivariate and multivariable logistic regression was used to identify factors associated with the reoccurrence of OIs. A P value of ≤0.05 was used to determine significant association. The results were reported as numerical figures, tables, and diagrams, based on the type of data. Results The mean ± standard deviation age of the 450 study participants was 34.3±8.47 years. Eighty patients (17.8%) had chronic disease. In total, 119 HIV/AIDS patients (26.4%) were diagnosed with reoccurrence of OIs. Pulmonary tuberculosis was the major reoccurring OI. Age, rural residence, chronic disease, baseline anti-retroviral therapy (ART) adherence, current hemoglobin level, and current cell differentiation-4 (CD4) count were factors significantly associated with reoccurrence. Conclusion Although the magnitude of reoccurrence of OIs was lower than in previous studies, efforts have to be continued among stakeholders to tackle factors associated with the reoccurrence of OIs.

Abstract
Background According to the World Health Organization, optimal adherence to Antiretroviral Therapy (ART) improves quality of life. Patients who use ART have varying characteristics in terms of where they live. The effect of place of residence on ART adherence is unclear in Ethiopia. Therefore, the aim of this systematic review and meta-analysis was to estimate the pooled association between place of residence and adherence to ART. Methods Articles were retrieved from PubMed, Scopus, African Journals Online (AJOL), Journal Storage (JSTOR), and Web of Science. The data was extracted using Microsoft Excel 2016 spreadsheet. Review Manager 5.3 and STATA version 14 were used for the analysis. The Cochrane Q statistic was used to assess between-study heterogeneity. I2 was used to quantify between-study heterogeneity. A weighted inverse variance random-effects model was used to calculate the pooled odds ratio with 95% confidence interval. Results Seven studies were included in this systematic review and meta-analysis. The Begg’s test (Z = 0.15, P = 0.881) and Egger’s test (t = 0.14, P = 0.894) revealed no evidence of publication bias. Urban residence was associated with an increased likelihood of good adherence (OR 2.07, 95%CI 1.22–3.51). Conclusions The study recommends that policy-makers should enact policies that increase access to ART services in a rural area in order to improve adherence. It is recommended that implementation studies be conducted in order to identify practical and affordable interventions.

Abstract
The oral cavity is colonized by a large number of microorganisms that are referred to collectively as the oral microbiota. These indigenous microorganisms have evolved in symbiotic relationships with the oral mucosal immune system and are involved in maintaining homeostasis in the oral cavity. Although Candida species are commonly found in the healthy oral cavity without causing infection, these fungi can become pathogenic. Recents advances indicate that the development of oral candidiasis is driven both by Candida albicans overgrowth in a dysbiotic microbiome and by disturbances in the host's immune system. Perturbation of the oral microbiota triggered by host-extrinsic (ie, medications), host-intrinsic (ie, host genetics), and microbiome-intrinsic (ie, microbial interactions) factors may increase the risk of oral candidiasis. In this review, we provide an overview of the oral mycobiome, with a particular focus on the interactions of Candida albicans with some of the most common oral bacteria and the oral mucosal immune system. Also, we present a summary of our current knowledge of the host-intrinsic and host-extrinsic factors that can predispose to oral candidiasis.

Comparative Efficacy of Antifungal Agents Used in the Treatment of Oropharyngeal Candidiasis among HIV-Infected Adults: A Systematic Review and Network Meta-Analysis. J Fungi (Basel) 2021; 7:jof7080637. [PMID: 34436176 PMCID: PMC8398874 DOI: 10.3390/jof7080637] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 07/18/2021] [Accepted: 07/29/2021] [Indexed: 12/22/2022] Open
Abstract
The objective of this study was to assess the comparative efficacy and safety of different antifungal agents used for the treatment of oropharyngeal candidiasis (OPC) in adult patients with HIV. A systematic search was performed on the four major databases (Medline, Embase, CENTRAL and Scopus) to identify randomized controlled trials (RCTs) that evaluated the efficacy of antifungal agents in HIV patients with OPC. A network meta-analysis was performed from the data extracted from the selected studies. The agents were ranked according using surface under the cumulative ranking (SUCRA). The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to determine the quality of evidence. A total of 15 trials were included in the quantitative analysis involving the data from a total of 2883 participants. Fluconazole was ranked as the most effective antifungal agent to achieve clinical cure (SUCRA = 0.87) in OPC followed by posaconazole and itraconazole. Posaconazole was ranked the most efficacious agent in achieving mycological cure (SUCRA = 0.81), followed by fluconazole. While nystatin was ranked the safest, the effect estimates of none of the other systemic antifungal agents were significantly higher than fluconazole. Based on the available evidence, fluconazole can be considered as the most effective drug in the treatment of OPC among HIV-infected adults and has a favorable safety profile, followed by posaconazole.

Abstract
Kaposi sarcoma (KS) is an AIDS-defining angio-proliferative malignancy highly prevalent in Sub-Saharan Africa. The main objective of this study was to determine the factors associated with recurrence of HIV-associated KS. We recruited a cohort of individuals on antiretroviral therapy who were in remission for HIV-associated KS after undergoing cytotoxic cancer chemotherapy. Collected variables included sociodemographic and clinical parameters, cytokines and chemokines, HIV viral loads, and CD4 counts. Compared to individuals who had KS recurrence, IL-5 was significantly higher at time of follow-up in individuals who had sustained remission (22.7pg/ml vs. 2.4pg/ml; p = 0.02); IL-6 was significantly higher at baseline and time of follow-up in individuals who had sustained remission, (18.4pg/ml vs. 0pg/ml; p = 0.01) and (18.0pg/ml vs. 0.18pg/ml; p = 0.03) respectively; IP-10 was significantly lower at baseline and at time of follow-up in individuals who had sustained remission, (534pg/ml vs. 920pg/ml; p = 0.04) and (446pg/ml vs.1098pg/ml; p = 0.01) respectively; while HIV viral load was significantly lower at baseline and at time of follow-up in individuals who had sustained remission, (0copies/ml vs. 113copies/ml; p = 0.004) and (0copies/ml vs. 152copies/ml; p = 0.025) respectively. Plasma levels of IL-5, IL-6, and IP-10 are associated with recurrence of HIV-associated KS, while persistently detectable HIV viral loads increase the risk of KS recurrence.

Abstract
BACKGROUND Chronic immunosuppressive therapy in solid organ transplant (SOT) recipients can trigger latent varicella zoster virus reactivation even in those with stable graft function. The inactivated herpes zoster (HZ) vaccine can be effective in preventing post-transplant HZ, which can cause severe neuralgia or disseminated disease. This meta-analysis aims to assess the incidences of HZ across transplant organs in SOT recipients. METHODS We included 12 observational studies (6560 recipients) from a PubMed and EMBASE search of articles through October 2019 and collected data from single-center dating from January 2001 to December 2017 (3498 recipients). The pooled HZ incidence and its differences between subgroups were obtained from random-effect models and meta-analysis of variance tests using R package. RESULTS The overall pooled crude incidence was 9.1% (95% confidence interval [CI], 7.6%-10.8%). The pooled incidence was similar between sexes but significantly different between transplanted organs (P < .001). Heart transplants (HT) (n = 644) have the highest pooled incidence with 15.2% (95% CI, 12.7%-18.2%), followed by lung transplants (LTX) (n = 780) with 11.0% (8.3%-14.4%). Kidney transplants (n = 5435) have the lowest incidence of 6.7 (5.1%-8.8%). The meta-regression analysis revealed that HZ development had a relationship with past graft rejection (P = .024). CONCLUSION These data support the need for subunit HZ vaccination in SOT recipients with a high risk for HZ, especially HT and LTX recipients, without respect to the late post-transplant period.

Abstract
INTRODUCTION The incidence of human immunodeficiency virus-1 (HIV-1) associated meningitis has been declining in the post-combination antiretroviral treatment (ART) era, although survival rates remain low for the common causes like tuberculosis and cryptococcal disease. Diagnosis and treatment of meningitis in HIV-1 is complicated by atypical clinical presentations, limited accuracy of diagnostic tests, access to diagnostic tests, and therapeutic agents in low- and middle-income countries (LMIC) and immune reconstitution inflammatory syndrome (IRIS). AREAS COVERED We provide an overview of the common etiologies of meningitis in HIV-1-infected adults, suggest a diagnostic approach based on readily available tests, and review specific chemotherapeutic agents, host-directed therapies, supportive care, timing of ART initiation, and considerations in the management of IRIS with a focus on resource-limited settings. They identify key knowledge gaps and suggest areas for future research. EXPERT OPINION Evidence-based management of HIV-1-associated meningitis is sparse for common etiologies. More readily available and sensitive diagnostic tests as well as standardized investigation strategies are required in LMIC. There is a lack of availability of recommended drugs in areas of high HIV-1 prevalence and a limited pipeline of novel chemotherapeutic agents. Host-directed therapies have been inadequately studied.
