Abstract
Introduction HIV-associated neurocognitive disorders (HAND) are becoming a significant public health concern in the continuum of human immune virus (HIV) treatment. These disorders range from subtle cognitive impairments to severe dementia. Despite many early-stage HAND cases being asymptomatic, healthcare workers (HCWs) rarely perform routine neurocognitive assessments. This leads to a high number of unrecognized cases and increases the risk of HAND among people living with HIV (PLWH). Material and Methods We aimed to explore HCWs' perspectives on integrating the International HIV Dementia Scale (IHDS) into routine care for screening HAND at The AIDS Support Organization (TASO) centres in central and southwestern Uganda. Results We conducted five focus group discussions with 37 HCWs from five TASO centres. Thematic analysis revealed eight key theme: 1) Impaired brain function, 2) Changes in activities of daily living, 3) Promotion of quality care perspectives, 4) Tool applicable and user-friendly, 5) Client increased self-awareness and self-confidence, 6) Integration of IHDS into routine HIV care, 7) Uncertainty about IHDS use, and 8) Continuous training for HCWs. Conclusion As PLWH enjoy longer and healthier lives, their risk for HAND increases, potentially affecting their quality of life. The use of the IHDS has raised awareness among HCWs and improved decision-making through cognitive assessments, emphasizing it value in PLWH. We recommend a prospective study to assess the long-term outcomes and efficacy of increased HAND screening. Furthermore, integrating a HAND screening module into the consolidated HIV guidelines is recommended to enhance its relevance.

Abstract
Background Health-seeking behavior towards herpes zoster is vital to find an appropriate remedy for patients and utilization of timely healthcare services can have an impact on good health outcomes. The study aimed to assess the health-seeking behavior and determinants among Herpes Zoster patients in public hospitals, South Wollo, Ethiopia. Method A hospital-based cross-sectional study was conducted from September 1, 2022, to November 30, 2022. The simple random sampling technique was used to select 419 participants. Pretested, structured questionnaires and patient interviews were used to collect the data. The bivariable analysis was done and variables with p-value <0.25 were further examined using a multivariable logistic regression model. AOR with a 95 % CI and a P-value <0.05 at a 5 % level of significance were considered. Results About 55.6 % of patients had poor health-seeking behavior towards herpes zoster, with a response rate of 99.1 %. Distance from health facilities (AOR = 4.9; 95 % CI: 1.33-10.35), being rural residence (AOR = 0.3; 95 % CI: 0.17-0.40), being illiterate (AOR = 5.9; 95 % CI: 3.40-10.32), poor self-care adherence (AOR = 1.8; 95 % CI = 1.14-3.07), moderate depression (AOR = 7.3; 95 % CI: 4.10-11.50), moderate (AOR = 0.3; 95 % CI: 0.10-0.70) and severe anxiety (AOR = 0.1; 95 % CI: 0.01-0.63), and duration more than seven days of herpes zoster (AOR = 3.1; 95 % CI = 1.42-6.97) were statistically significant. Conclusion Nearly half of the study participants had poor health-seeking behavior. Being a rural resident and illiterate, poor self-care adherence, moderate and severe anxiety, moderate depression, and duration of more than 7 days were significantly associated. with health-seeking behavior towards Herpes Zoster. Proper guidance, psychological support, and awareness creation about Herpes Zoster severity and complications.

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
Inhalation of crystalline silica-rich dust particles can result in the deadly occupational lung disorder called silicosis. The risk of contracting tuberculosis (TB) and the potential for lung cancer increase due to silicosis. This review article aims to bring to light the state of silicosis and TB scenario in the world and India for evaluating hurdles in the present and future to achieve the elimination road map and assess these conditions in the backdrop of the COVID-19 pandemic. A patient with silicosis has a 2.8-2.9 times higher risk of developing pulmonary TB and 3.7 times that of extrapulmonary TB. Incidences of missed cases when TB was misdiagnosed with silicosis due to indifferent clinical manifestations of the two in the initial stages are not uncommon. The duration of silica exposure and silicosis severity are directly related to the propensity to develop TB. As per a study, an average gap of 7.6 years has been noticed in a South African population for silico-tuberculosis to develop post-silicosis. In a study done on mine workers at Jodhpur, Rajasthan, it was seen that there is no definitive relation between patients with silicosis and the possibility of having COVID-19. There is a significant need to integrate the Silicosis control program with the TB elimination program for the government. A few steps can include assessing the workplaces, periodic monitoring of the workers' health, active case surveillance, identification of hotspots, and introducing reforms to curb the spread of dust and particulate matter from industrialised areas be taken in this regard.

Abstract
Understanding the characteristics of people living with HIV who interrupt antiretroviral therapy (ART) is critical for designing client-centered services to ensure optimal outcomes. We assessed predictors of treatment interruption in 22 HIV clinics in Nigeria. We reviewed records of HIV-positive patients aged ≥15 years who started ART 1 January and 31 March 2019. We determined treatment status over 12 months as either active, or interrupted treatment (defined as interruption in treatment up to 28 days or longer). Potential predictors were assessed using Cox hazard regression models. Overall, 1185 patients were enrolled on ART, 829 (70%) were female, and median age was 32 years. Retention at 1, 3, 6, 9, and 12 months was 85%, 80%, 76%, 72%, and 68%, respectively. Predictors of treatment interruption were post-secondary education (p = 0.04), diagnosis through voluntary counseling and testing (p < 0.001), receiving care at low-volume facilities (p < 0.001), lack of access to a peer counselor (p < 0.001), and residing outside the clinic catchment area (p = 0.03). Treatment interruption was common but can be improved by focusing on lower volume health facilities, providing peer support especially to those with higher education, and client-centered HIV services for those who live further from clinics..

Abstract
BACKGROUND Fungal infections are common causes of death and morbidity in those with advanced HIV infection. Data on access to diagnostic tests in Africa are scarce. We aimed to evaluate the diagnostic capacity for invasive fungal infections in advanced HIV disease in Africa. METHODS We did a continent-wide survey by collecting data from 48 of 49 target countries across Africa with a population of more than 1 million; for Lesotho, only information on the provision of cryptococcal antigen testing was obtained. This survey covered 99·65% of the African population. We did the survey in six stages: first, questionnaire development, adaptation, and improvement; second, questionnaire completion by in-country respondents; third, questionnaire review and data analysis followed by video conference calls with respondents; fourth, external validation from public or private sources; fifth, country validation by video conference with senior figures in the Ministry of Health; and sixth, through five regional webinars led by the Africa Centres for Disease Control and Prevention with individual country profiles exchanged by email. Data was compiled and visualised using the Quantum Geographic Information System software and Natural Earth vectors to design maps showing access. FINDINGS Data were collected between Oct 1, 2020, and Oct 31, 2022 in the 48 target countries. We found that cryptococcal antigen testing is frequently accessible to 358·39 million (25·5%) people in 14 African countries. Over 1031·49 million (73·3%) of 1·4 billion African people have access to a lumbar puncture. India ink microscopy is frequently accessible to 471·03 million (33·5%) people in 23 African countries. About 1041·62 million (74·0%) and 1105·11 million (78·5%) people in Africa do not have access to histoplasmosis and Pneumocystis pneumonia diagnostics in either private or public facilities, respectively. Fungal culture is available in 41 countries covering a population of 1·289 billion (94%) people in Africa. MRI is routinely accessible to 453·59 million (32·2%) people in Africa and occasionally to 390·58 million (27·8%) people. There was a moderate correlation between antiretroviral therapy usage and external expenditure on HIV care (R2=0·42) but almost none between external expenditure and AIDS death rate (R2=0·18), when analysed for 40 African countries. INTERPRETATION This survey highlights the enormous challenges in the diagnosis of HIV-associated Pneumocystis pneumonia, cryptococcal disease, histoplasmosis, and other fungal infections in Africa. Urgent political and global health leadership could improve the diagnosis of fungal infections in Africa, reducing avoidable deaths. FUNDING Global Action For Fungal Infections.

Abstract
The human immunodeficiency virus (HIV) remains one of the greatest challenges of the twenty-first century in the absence of an effective vaccine or cure. It is estimated globally that close to 38 million people are currently living with the HIV virus and more than 36 million have succumbed to this deadly virus from the time the first case was reported in early 1980s. The virus degrades the human body immunity and makes it more vulnerable to different kinds of opportunistic infections (OIs). However, with the introduction of highly active anti-retroviral therapy (HAART) in 2003, the pattern and frequency of OIs has been progressively changing though with variations in the different parts of the World. So this chapter discusses the temporal and spatial patterns of OIs in Uganda.

Abstract
Opportunistic infections (OIs) in HIV patients are infections that are more common or more severe as a result of HIV-mediated immunosuppression. The advances in the capacity of antiretroviral therapy (ART) have diminished the incidence of OIs. However, even in the ART era, HIV-related OIs continue to be major causes of hospitalization and mortality. Therefore, this study aims to identify time to occurrence, predictors, and patterns of OIs incidence among HIV-positive patients attending ART clinic of Salale University Comprehensive Specialized Hospital, Ethiopia. A retrospective cohort study was conducted between 1st September 2016 and 1st September 2021. All 419 patients diagnosed during the study period were recruited. Data were extracted from both patient medical records and ART logbooks. Stata-16 was used for data analysis. Follow-up time was calculated from the date of HIV diagnosis to the date of OIs occurrence or censoring. Cox proportional hazards regression model was used to identify the predictors of OIs incidence. The total person-time of the follow-up was 8656 person-months of observation. During the follow-up time, 199 (47.49%) of the patients had developed OIs. The incidence rate of OIs was 23 (95%CI: 20, 26) per 1000 person-months of observation. The median OIs free survival time was 36 (95%CI: 31, 40) months. Predictors such as residence, cd4 category, baseline hemoglobin level, ART side effects, isoniazid preventive therapy, and chronic disease comorbidity were significantly predicted OIs incidence. The study area's OIs incidence remained high, requiring prompt action. To reduce the morbidity and mortality associated with OIs, HIV-positive patients with the predictors of rural residence, low CD4 category, low baseline hemoglobin level, ART side effects, not taking IPT, and baseline chronic disease comorbidity necessitate close follow-up and monitoring. Thus, we recommend focused and evidence-informed strategies to address OIs burden and improve outcomes.

Abstract
BACKGROUND Worldwide despite the availability of antiretroviral therapy, human immunodeficiency virus/acquired immunodeficiency syndrome still causes morbidity and mortality among patients. In Sub-Saharan Africa, human immunodeficiency virus/acquired immunodeficiency syndrome remains a major public health concern. The aim of this study was to identify the causes of morbidity and mortality in the modern antiretroviral therapy era in Sub-Saharan Africa. METHODS We conducted a systematic review according to the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. We searched relevant studies from 3 databases which are Google Scholar, PubMed, and CINAHL. Two review authors independently screened titles, abstracts, and full-text articles in duplicate, extracted data, and assessed bias. Discrepancies were resolved by discussion or arbitration of a third review author. R software version 3.6.2 was used to analyze the data. Maximum values were used in order to show which disease was mostly spread out by looking at the highest prevalence reported. This systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO). RESULTS A total of 409 articles were obtained from the database search, finally 12 articles met the inclusion criteria and were eligible for data extraction. Among them, 3 were conducted in Nigeria, 2 were conducted in Uganda, 3 were conducted in South Africa, 1 in Gabon, 1 in Ethiopia, 1 in Ghana, and 1 in Burkina Faso. In most of the included studies, tuberculosis was the leading cause of hospitalization which accounted for between 18% and 40.7% and it was also the leading cause of death and accounted for between 16% and 44.3%, except in 1 which reported anemia as the leading cause of hospitalization and in 2 which reported wasting syndrome and meningitis respectively as the leading causes of death. Opportunistic malignancies accounted between for 1.8% to 5% of hospitalization and 1.2% to 9.8% of deaths. CONCLUSIONS Tuberculosis is the commonest cause of hospitalization and death in Sub-Saharan Africa, but it is always followed by other infectious disease and other non-AIDS related causes.

Abstract
Background Children younger than 15 years, carry almost 80% of the global burden of HIV/AIDS. HIV worsens the progression of latent TB to active TB disease. Although antiretroviral treatment has shown marked reduction in Tuberculosis incidence, TB continues to occur in Sub-Saharan countries including Ethiopia. The aim of this study was to investigate the impact of HAART on the incidence of tuberculosis among children infected with HIV in Southwest Ethiopia. Methods A retrospective cohort study was conducted between 2009 to 2014. We used chi-square test, and Mann-Whitney U test to compare non-HAART and HAART cohort. We estimated the effect of HAART on TB incidence using marginal structural model after adjusting for time-dependent confounders affected by exposure. Result A total of 844 children were followed. We observed them for a median of 51 months (IQR 31) and a total of 2942.99 child-years. The overall TB incidence rate was 7.917 per 100 child years (95% CI, 6.933–9.002). TB incidence for specific HAART and non-HAART cohort were 7.67 per 100 child-years (95% CI, 6.318–9.217) and 8.17 per 100 child-years (95% CI, 6.772–9.767) respectively. From marginal structural modeling, children on HAART were 36% (HR=0.642, 95% CI 0.442–0.931, p<0.02) less likely to develop TB compared to those who were not. Conclusion HAART reduced the hazard of TB in HIV-infected children by 36%. This is by far less than what is expected.

Abstract
BACKGROUND HIV-Associated Neurocognitive Disorder (HAND remains a pronounced consequence of HIV/AIDS despite improved life expectancies. This is often associated with several dysfunctions such as decrease of attention, mood alterations and psychomotor disturbances. Many factors, including age, gender, employment status, and psychiatric disorders, have been associated with HAND. Among the associated psychiatric disorders, depression is often more prevalent. It can influence not only quality of life, relationships and employment but also adherence to medical care. We assessed the prevalence of depression and its association with HAND among people living with HIV in rural Southwestern Uganda. METHODS This was a cross-sectional study that used Beck Depression Inventory-1 and International HIV Dementia Scale to assess depression and HAND respectively. We defined depression with a score of > 10 and HAND with a cutoff score of ≤10. We conducted data analysis using STATA version 12, and Pearson Chi-square test and logistic regression to determine associations between depression and HAND. The level of statistical significance was set at p ≤ 0.05. Ethical approval and administrative clearance were obtained from relevant bodies. RESULTS Of the 393 participants assessed for depression and HAND, 27% had depression and 58.3% screened positive for HAND. All levels of depression were more prevalent among female participants. We found a significant association between depression and HIV associated neurocognitive disorders (χ2 (3) = 9.0538 p = 0.029). CONCLUSION Our findings confirmed a high prevalence of depression in individuals with HAND which is a major component of the disease burden.

Abstract
Background Opportunistic infections are late complications of HIV infection due to the depletion of the immune system. It is a major public health problem and high morbidity AIDS patients die of AIDS-related infections in developing countries like Ethiopia. Identification of opportunistic infections (OIs) is important to develop a specific intervention. Therefore, the aim of this study was to assess the burden and associated factors of opportunistic infections. Methods A facility-based cross-sectional study was conducted on 420 randomly selected HIV/AIDS patients taking anti-retroviral therapy. Data were collected from selected hospitals in Sidama Regional State based on population proportion to size. Data were collected by a pre-tested questionnaire and a pre-tested checklist from the medical records of patients. Data were entered and analyzed for descriptive and logistic regression models by SPSS v.23. The result declared as statistically significant at p < 0.05. Results The magnitude of opportunistic infections was 39.6%. Major identified OIs were oral candidiasis 23.2%, recurrent bacterial pneumonia 21.5%, herpes zoster 6.3%, and pulmonary tuberculosis 6.0%. The magnitude of opportunistic associated with older age [AOR=3.50, 95% CI:1.85, 6.61], no formal education [AOR=4.54, 95% CI:1.81, 11.37], initial CD4 count less than 200 cells/mm3 [AOR=3.10, 95% CI:1.61, 5.96], who interrupt ART medicines [AOR=3.21, 95% CI:1.86, 5.56] and khat chewing [AOR=4.24, 95% CI:2.07, 8.68] when compared to their counterparts. Conclusion The overall magnitude of opportunistic infections was high when compared with other studies. Health officials and clinicians need to give attention to the strengthening of the provision if ART with prophylaxis on early stage and adherence, implementation of the TB/HIV collaboration activity, and early initiation of ART to reduce opportunistic infections.

Abstract
Advances in treatment of HIV have dramatically improved survival rates; HIV-associated neurocognitive disorders (HAND), however, remain highly prevalent and continue to represent a significant public health problem, especially in resource-limited settings. We completed a cross-sectional study to describe the prevalence and risk factors for HAND in rural Southwestern Uganda AIDS Support Organization Centers. After securing ethical clearance from relevant bodies, 393 participants were screened for HAND using the International HIV Dementia Scale. A cutoff score of ≤10 and a significance level of p ≤ .05 were set. More than half of the 393 participants (n = 229, 58.23%) screened positive for HAND. The associated risk factors were gender (odds ratio [OR] 0.54, p = .017), peasant farming (OR 1.70, p = .04), and older age (OR 1.03, p = .019). HIV-associated neurocognitive disorder remains one of the major complications of HIV despite improvement in antiretroviral therapy and life expectancies.

Abstract
Purpose Data comparing the burden of the opportunistic infections among the Pre-ART and On-ART HIV-infected patients in Ethiopia are scarce. Therefore, this study aimed to compare the prevalence and predictors of opportunistic infections in Pre-ART and On-ART HIV-infected patients. Methods A comparative cross-sectional study was conducted among adult patients infected with HIV and who were on Pre-ART or On-ART and followed up from 2012 to 2016 in Zewditu Memorial Hospital, Addis Ababa. Those patients who were infected with HIV, but not eligible for ART were categorized under Pre-ART follow-up (n=192) and those patients who started taking ART were categorized under the On-ART follow-up group (n=192). Patients were included in the study by using simple random sampling technique from the list of the patients registered in the ART follow-up database. The presence of opportunistic infections along with clinical findings and baseline laboratory data was extracted from the ART follow-up database and the medical records of the patients using a standardized checklist. Factors associated with the development of opportunistic infections were analyzed using multi-variable binary logistic regression analysis. Results The overall prevalence of opportunistic infections was found to be 33.6% (95% CI; 28.9-38.5). The prevalence of opportunistic infections among the Pre-ART group (38%) was higher than On-ART group (29.2%) (P-value = 0.04). Pulmonary tuberculosis was the most common opportunistic infection observed in both Pre-ART and On-ART groups. Being in the WHO clinical Stage III (AOR = 2.1; 95% CI 1.1-3.9) or Stage IV (AOR = 3.6; 95% CI 1.7-7.7) were independent predictors for the development of opportunistic infections. Conclusion The prevalence of opportunistic infections among the HIV-infected patients who were in Pre-ART was higher than On-ART group. This finding reinforces the need for early initiation of ART for HIV-infected patients irrespective of their CD4 counts.

Abstract
Namibia is a sub-Saharan country with one of the highest HIV infection rates in the world. Although care and support services are available that cater for opportunistic infections related to HIV, the main focus is narrow and predominantly aimed at tuberculosis. We aimed to estimate the burden of serious fungal infections in Namibia, currently unknown, based on the size of the population at risk and available epidemiological data. Data were obtained from the World Health Organization (WHO), Joint United Nations Programme on HIV/AIDS (UNAIDS), and published reports. When no data existed, risk populations were used to estimate the frequencies of fungal infections, using the previously described methodology. The population of Namibia in 2011 was estimated at 2,459,000 and 37% were children. Among approximately 516,390 adult women, recurrent vulvovaginal candidiasis (≥4 episodes /year) is estimated to occur in 37,390 (3003/100,000 females). Using a low international average rate of 5/100,000, we estimated 125 cases of candidemia, and 19 patients with intra-abdominal candidiasis. Among survivors of pulmonary tuberculosis (TB) in Namibia 2017, 112 new cases of chronic pulmonary aspergillosis (CPA) are likely, a prevalence of 354 post-TB and a total prevalence estimate of 453 CPA patients in all. Asthma affects 11.2% of adults, 178,483 people, and so allergic bronchopulmonary aspergillosis (ABPA) and severe asthma with fungal sensitization (SAFS) were estimated in approximately 179/100,000 and 237/100,000 people, respectively. Invasive aspergillosis (IA) is estimated to affect 15 patients following leukaemia therapy, and an estimated 0.13% patients admitted to hospital with chronic obstructive pulmonary disease (COPD) (259) and 4% of HIV-related deaths (108) — a total of 383 people. The total HIV-infected population is estimated at 200,000, with 32,371 not on antiretroviral therapy (ART). Among HIV-infected patients, 543 cases of cryptococcal meningitis and 836 cases of Pneumocystis pneumonia are estimated each year. Tinea capitis infections were estimated at 53,784 cases, and mucormycosis at five cases. Data were missing for fungal keratitis and skin neglected fungal tropical diseases such as mycetoma. The present study indicates that approximately 5% of the Namibian population is affected by fungal infections. This study is not an epidemiological study—it illustrates estimates based on assumptions derived from similar studies. The estimates are incomplete and need further epidemiological and diagnostic studies to corroborate, amend them, and improve the diagnosis and management of these diseases.

Abstract
AIM The aim of the study was to assess the predictors of ocular surface squamous neoplasia (OSSN) and conjunctival squamous cell carcinoma (SCC) among Ugandan patients. MATERIALS AND METHODS Patients presenting for removal of ocular surface lesions received human immunodeficiency virus (HIV) testing, completed questionnaires about demographic, behavioral, and historical potential risk factors for conjunctival neoplasia, and had lesions examined for interpalpebral versus other locations, rough versus smooth texture, and number of feeder vessels. Biopsies were classified pathologically using standard definitions classified OSSN and SCC. HIV rates were calculated for patients: with OSSN, SCC, and benign lesions. Potential risk factors and gross findings were tested for abilities to predict OSSN and SCC. RESULTS One hundred and ninety-five patients presented with 212 lesions in 203 eyes. Nearly 34% of the patients were more than 60 years old, 67% were peasants, 88% spent more than 20 h/week outdoors, and only 10% wore sun protection. No potential risk factors predicted neoplasia. HIV prevalence was 17.1% among patients with OSSN compared to 11.1% among those without OSSN; 42.9% among SCC patients compared to 12.0% among those without SCC. Rough tumor surface (adjusted odds ratio [aOR] = 4.4 and 95% confidence interval [CI]: 2.2-9.1), six or more feeder vessels (aOR = 2.6, 95% CI: 1.3-5.2), and interpalpebral tumor location (aOR = 3.3, 95% CI: 1.5-7.1) predicted OSSN. Only a rough tumor surface (aOR = 34.6, 95% CI: 7.8-153.4) predicted SCC. CONCLUSION HIV infection remained a risk factor for OSSN and particularly, SCC, but less so than in the past. Lesions' rough surface, six or more feeder vessels, and interpalpebral location increased OSSN risk. Only a rough tumor surface increased risk for SCC.

Abstract
BACKGROUND Despite increased antiretroviral therapy (ART) coverage and the raised CD4 threshold for starting ART, opportunistic infections (OIs) are still one of the leading causes of death in sub-Saharan Africa. There are few studies from resource-limited settings on long-term reporting of OIs other than tuberculosis. METHODS Patients starting ART between April 2004 and April 2005 were enrolled and followed-up for 10 years in Kampala, Uganda. We report incidences, patterns and risk factors using Cox proportional hazards models of OIs among all patients and among patients with CD4 cell counts >200 cells/μL. RESULTS Of the 559 patients starting ART, 164 patients developed a total of 241 OIs during 10 years of follow-up. The overall incidence was highest for oral candidiasis (25.4, 95% confidence interval (CI): 20.5-31.6 per 1000 person-years of follow-up), followed by tuberculosis (15.3, 95% CI: 11.7-20.1), herpes zoster (12.3, 95% CI: 9.1-16.6) and cryptococcal meningitis (3.0, 95% CI: 1.7-5.5). Incidence rates for all OIs were highest in the first year after ART initiation and decreased with the increase of the current CD4 cell count. Factors independently associated with development of OIs were baseline nevirapine-based regimens, time-varying higher viral load, time-varying lower CD4 cell count and time-varying lower hemoglobin. In patients developing OIs at a current CD4 cell count >200 cells/μL, factors independently associated with OI development were time-varying increase in viral load and time-varying decrease in hemoglobin, whereas a baseline CD4 cell count <50 cells/μL was protective. CONCLUSION We report high early incidences of OIs, decreasing with increasing CD4 cell count and time spent on ART. Ongoing HIV replication and anemia were strong predictors for OI development independent of the CD4 cell count. Our findings support the recommendation for early initiation of ART and suggest close monitoring for OIs among patients recently started on ART, with low CD4 cell count, high viral load and anemia.

Understanding the current trends in AOI-related morbidity/mortality is essential in improving patient care and optimizing current public health strategies to further reduce AOIs in Taiwan in the era of contemporary highly active antiretroviral therapy (HAART). METHODS Eligible patients were evaluated at two referral centers between 2010 and 2015. The patients were stratified by date of diagnosis into three periods: 2010-2011, 2012-2013, and 2014-2015. The demographics, HIV stage at presentation according to the United States CDC 2014 case definition, laboratory variables, and the occurrence of AOIs and associated outcomes were compared among the patients. Logistic regression and Cox regression were respectively used to identify variables associated with the occurrence of AOIs within 90 days of HIV enrollment and all-cause mortality. RESULTS Over a mean observation period of 469 days, 1264 patients with newly diagnosed HIV with a mean age of 29 years and mean CD4 count of 275 cells/μL experienced 394 AOI episodes in 290 events. At presentation, 37.7% of the patients had AIDS; the frequency did not significantly differ across groups. The overall proportion of AOIs within the study period was 21.0%, and no decline across groups was observed. The majority of AOIs (91.7%) developed within 90 days of enrollment. All-cause and AOI-related mortality did not significantly differ across groups. Throughout the three study periods, AOIs remained the main cause of death (47/56, 83.9%), especially within 180 days of enrollment (40/42, 95.2%). A CD4 cell count of < 200 cells/μL at presentation was associated with increased adjusted odds of an AOI within 90 days [adjusted odds ratio, 40.84; 95% confidence intervals (CI), 12.59-132.49] and an elevated adjusted hazard of all-cause mortality (adjusted hazard ratio, 11.03; 95% CI, 1.51-80.64). CONCLUSIONS Despite efforts toward HIV prevention and management, early HIV care in Taiwan continues to be critically affected by AOI-related morbidity and mortality in the era of contemporary HAART. Additional targeted interventions are required for the earlier diagnosis of patients with HIV.

Abstract
We examined the incidence of herpes zoster (HZ) before and after the initiation of antiretroviral therapy (ART), and risk factors for HZ among human immunodeficiency virus (HIV)-infected individuals in Tanzania. A cohort study was conducted among HIV-positive individuals enrolled in HIV care and treatment clinics in Dar es Salaam, Tanzania. A Cox proportional hazard model was used to examine the effect of ART on the risk of HZ after adjusting for sociodemographics and time-varying clinical and nutritional factors. Among 72,670 HIV-positive individuals, 2,312 incident cases of HZ (3.2%) occurred during the median follow-up of 15 months (interquartile range: 3-35). The incidence rate of HZ significantly declined from 48.9 (95% confidence interval [CI] = 46.7-51.0) per 1,000 person-years before ART to 3.7 (95% CI = 3.3-4.1) per 1,000 person-years after the initiation of ART (P < 0.001). The risk of HZ declined with longer duration on ART. Low CD4 cell count, older age, female sex, district of Dar es Salaam, and year of enrollment were independently associated with the risk of HZ in the multivariate analysis. Low body mass index and anemia were not associated with the risk of HZ. The risk of HZ substantially declined after ART initiation in this large cohort of HIV-infected individuals. Earlier initiation of ART could reduce the risk of HZ and other opportunistic infections among HIV-infected individuals in sub-Saharan Africa.

Abstract
The landscape of human immunodeficiency virus (HIV) infection is changing with the increasing coverage of antiretroviral therapy (ART). Patients are living longer but continually exposed to a virologically suppressed HIV infection. This has resulted in a decrease in acquired immune deficiency syndrome (AIDS)-related complications such as opportunistic infections, and an increase in non-AIDS complications such as stroke. In this era, stroke is perhaps the most important neurologic complication of HIV infection. Furthermore, stroke is more of a heterogeneous disease in people living with HIV infection and therefore needs to be approached systematically. Many of the etiologies are treatable. HIV-associated vasculopathy is perhaps the most common etiology in this population and our understanding of this is still evolving. Moreover, the treatment of HIV infection may contribute to an excess risk of stroke and interact with stroke therapies.

Abstract
BACKGROUND Varicella zoster virus (VZV) causes varicella and herpes zoster. These vaccine preventable diseases are common globally. Most available data on VZV epidemiology are from industrialised temperate countries and cannot be used to guide decisions on the immunization policy against VZV in Africa. This systematic review aims to review the published data on VZV morbidity and mortality in Africa. METHODS All published studies conducted in Africa from 1974 to 2015 were eligible. Eligible studies must have reported any VZV epidemiological measure (incidence, prevalence, hospitalization rate and mortality rate). For inclusion in the review, studies must have used a defined VZV case definition, be it clinical or laboratory-based. RESULTS Twenty articles from 13 African countries were included in the review. Most included studies were cross-sectional, conducted on hospitalized patients, and half of the studies used varying serological methods for diagnosis. VZV seroprevalence was very high among adults. Limited data on VZV seroprevalence in children showed very low seropositivity to anti-VZV antibodies. Co-morbidity with VZV was common. CONCLUSION There is lack of quality data that could be used to develop VZV control programmes, including vaccination, in Africa. TRIAL REGISTRATION PROSPERO 2015: CRD42015026144 .

Reevaluating Cumulative HIV-1 Viral Load as a Prognostic Predictor: Predicting Opportunistic Infection Incidence and Mortality in a Ugandan Cohort. Am J Epidemiol 2016; 184:67-77. [PMID: 27188943 DOI: 10.1093/aje/kwv303] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2015] [Accepted: 10/29/2015] [Indexed: 11/12/2022] Open
Abstract
Recent studies have evaluated cumulative human immunodeficiency virus type 1 (HIV-1) viral load (cVL) for predicting disease outcomes, with discrepant results. We reviewed the disparate methodological approaches taken and evaluated the prognostic utility of cVL in a resource-limited setting. Using data on the Infectious Diseases Institute (Makerere University, Kampala, Uganda) cohort, who initiated antiretroviral therapy in 2004-2005 and were followed up for 9 years, we calculated patients' time-updated cVL by summing the area under their viral load curves on either a linear scale (cVL1) or a logarithmic scale (cVL2). Using Cox proportional hazards models, we evaluated both metrics as predictors of incident opportunistic infections and mortality. Among 489 patients analyzed, neither cVL measure was a statistically significant predictor of opportunistic infection risk. In contrast, cVL2 (but not cVL1) was a statistically significant predictor of mortality, with each log10 increase corresponding to a 1.63-fold (95% confidence interval: 1.02, 2.60) elevation in mortality risk when cVL2 was accumulated from baseline. However, whether cVL is predictive or not hinges on difficult choices surrounding the cVL metric and statistical model employed. Previous studies may have suffered from confounding bias due to their focus on cVL1, which strongly correlates with other variables. Further methodological development is needed to illuminate whether the inconsistent predictive utility of cVL arises from causal relationships or from statistical artifacts.
