AIDS-Defining Illnesses at Initial Diagnosis of HIV in a Large Guatemalan Cohort

Factors influencing histoplasmosis incidence in multidrug-resistant pulmonary tuberculosis patients: A cross-sectional study in Indonesia

Histoplasmosis is an infectious disease caused by the dimorphic fungus Histoplasma capsulatum, which in chronic conditions, is generally difficult to distinguish from pulmonary tuberculosis (TB) based on its clinical appearance; therefore, diagnostic errors could occur. Meanwhile, the prevalence of multidrug-resistant pulmonary TB (MDR-TB) in Indonesia remains high. Study determining the incidence of histoplasmosis in MDR-TB is unavailable worldwide. The aim of this study was to determine the risk factors of histoplasmosis incidence in MDR-TB patients in Indonesia. A cross-sectional was conducted at H. Adam Malik General Hospital, Medan, Indonesia and the ELISA platform (semi-quantitative) was used to detect histoplasma antibodies. Factors associated with histoplasmosis incidence among MDR-TB were determined using a Chi-squared test. A total of 50 MDR-TB patients were included this study of which 14 of them (28%) had histoplasmosis. The majority of histoplasmosis occurred in males, in MDR-TB patients with a history of TB treatment and among who had chest x-rays with far-advanced lesions. However, statistical analyses indicated none of those factors (sex, TB treatment history, status of the lung) as well as age group, acid-fast bacillus result, Mycobacterium tuberculosis culture result, having pet, living in damp house, working in the field or plantation, having HIV infection and smoking status were associated with histoplasmosis incidence. This study highlights that the incidence of histoplasmosis is relatively high and therefore further studies are important to be conducted in Indonesia that has a high MDR-TB cases.

Clinical and non-clinical determinants of cervical cancer mortality: A retrospective cohort study in Lagos, Nigeria

Introduction

Cervical cancer (CCa) is the fourth most frequent and a common cause of cancer mortality in women, the majority of whom live in low- and middle-income countries. Data on CCa mortality and its determinants have been poorly studied in Nigeria, resulting in a paucity of information that can assist patient management and cancer control policy.

Aim

The purpose of this study was to assess the mortality rate among CCa patients in Nigeria as well as the major factors influencing CCa mortality.

Study design

Data from the medical records of 343 CCa patients seen at the Lagos University Teaching Hospital and NSIA-LUTH Cancer Center from 2015 to 2021 were used in a retrospective cohort analysis. The hazard ratios (HR) and confidence intervals (CI) associated with the exposure variables and CCa mortality were calculated using Cox proportional hazard regression.

Results

The CCa mortality rate was 30.5 per 100 women-years after 2.2 years of median follow-up. Clinical factors such as HIV/AIDS (adjusted HR [aHR]: 11.9; 95% CI: 4.6, 30.4), advanced clinical stage (aHR: 2.7; 95% CI: 1.5, 4.7), and anemia at presentation (aHR: 1.8; 95% CI: 1.1, 3.0) were associated with a higher mortality risk, as were non-clinical factors such as age at diagnosis >50 years (aHR: 1.4; 95% CI: 1.0, 1.9) and family history of CCa (aHR: 3.5; 95%CI: 1.1, 11.1).

Conclusion

CCa has a high mortality rate in Nigeria. Incorporating these clinical and non-clinical factors into CCa management and control policies may improve women's outcomes.

Risk factors for mortality and multidrug resistance in pulmonary tuberculosis in Guatemala: A retrospective analysis of mandatory reporting

•

National TB cohort analyzing risk factors associated with MDR-TB and mortality in Guatemala.

•

Indigenous ethnicity and prior TB treatment were associated with increased risk of mortality and MDR-TB.

•

HIV/Unknown HIV status were associated with increased mortality and diabetes with risk for MDR-TB.

Background

Risk factors for mortality and MDR-TB in Guatemala are poorly understood. We aimed to identify risk factors to assist in targeting public health interventions.

Methods

We performed a retrospective study of adults with pulmonary TB reported to the Guatemalan TB Program between January 1, 2016 and December 31, 2017. The primary objective was to determine risk factors for mortality in pulmonary TB. The secondary objective was to determine risk factors associated with MDR-TB.

Results

Among 3,945 patients with pulmonary TB, median age was 39 years (IQR 25–54), 59% were male, 25% of indigenous ethnicity, 1.1% had MDR-TB and 3.9% died. On multivariable analysis, previous TB treatment (odds ratio [OR] 3.57, CI 2.24–5.68 [p < 0.001]), living with HIV (OR 3.98, CI 2.4–6.17 [p < 0.001]), unknown HIV diagnosis (OR 2.65, CI 1.68–4.18 [p < 0.001]), indigenous ethnicity (OR 1.79, CI 1.18–2.7 [p = 0.005]), malnutrition (OR 7.33, CI 3.24–16.59 [p < 0.001]), and lower educational attainment (OR 2.86, CI 1.43–5.88 [p = 0.003]) were associated with mortality. Prior treatment (OR 53.76, CI 25.04–115.43 [p < 0.001]), diabetes (OR 4.13, CI 2.04–8.35 [p < 0.001]), and indigenous ethnicity (OR 11.83, CI 1.46–95.73 [p = 0.02]) were associated with MDR-TB.

Conclusions

In Guatemala, both previous TB treatment and indigenous ethnicity were associated with higher TB mortality and MDR-TB risk among patients with pulmonary TB.

COVID-19, HIV-Associated Cryptococcal Meningitis, Disseminated Tuberculosis and Acute Ischaemic Stroke: A Fatal Foursome

Background

Several viral, bacterial and fungal co-infections have been associated with increased morbidity and mortality among patients with COVID-19. We report a fatal case of severe COVID-19 pneumonia in a patient with a recent diagnosis of advanced HIV disease complicated by cryptococcal meningitis, disseminated tuberculosis and acute ischemic stroke.

Case Presentation

A 37-year-old Ugandan woman was diagnosed with HIV infection 8 days prior to her referral to our center. She was antiretroviral naïve. Her chief complaints were worsening cough, difficulty in breathing, fever and altered mental status for 3 days with a background of a 1-month history of coughing with associated drenching night sweats and weight loss. The reverse transcriptase-polymerase chain reaction for SARS-CoV-2 of her nasopharyngeal swab sample was positive. Chest radiograph demonstrated military pattern involvement of both lungs. The serum and cerebrospinal fluid cryptococcal antigen tests were positive. Urine lipoarabinomannan and sputum GeneXpert were positive for Mycobacterium tuberculosis. Computed tomography of the brain showed a large acute ischemic infarct in the territory of the right middle cerebral artery. Regardless of the initiation of treatment, that is, fluconazole 1200 mg once daily, enoxaparin 60 mg, intravenous (IV) dexamethasone 6 mg once daily, oral fluconazole 1200 mg once daily, IV piperacillin/tazobactam 4.5 g three times daily and oxygen therapy, the patient passed on within 36 hours of admission.

Conclusion

Co-infections worsen COVID-19 outcomes.

Social Capital in Old People Living with HIV Is Associated with Quality of Life: A Cross-Sectional Study in China

Objective

Old people living with HIV (PLWH) are experiencing a lower quality of life (QoL) than their younger counterparts and have received insufficient attention in China. Given that social capital has been proven to be effective in improving QoL in other countries, we aimed to examine the association between social capital and QoL among old PLWH in China.

Methods

The data presented in this study was based on the baseline sample of an ongoing observational prospective cohort study, which was carried out from November 2018 to February 2019. Participants were old PLWH aged ≥50 in Sichuan, China, and were recruited by stratified multistage cluster sampling from 30 communities/towns. A total of 529 eligible participants finished the face-to-face investigation to measure their social capital (i.e., individual and family- (IF-) based social capital and community and society- (CS-) based social capital) and QoL. The QoL's dimensions of physical health summary (PCS) and mental health summary (MCS) were taken as dependent variables. Stepwise linear regression models were used to examine the association between social capital and QoL.

Results

After considering all significant covariates, the PCS was nonsignificantly correlated with IF-based social capital (β = −0.08, 95% CI [-0.28-0.11]) and CS-based social capital (β = 0.28, 95% CI [-0.03-0.59]), and MCS was significantly correlated with IF-based social capital (β = 0.77, 95% CI [0.54-0.99], p < 0.001) and CS-based social capital (β = 0.40, 95% CI [0.08-0.72], p < 0.05).

Conclusion

Targeted interventions related to building up social capital should be applied to improve the QoL of old PLWH. Providing extra relief funds and allowances might be helpful to improve PCS; improving community networking and engagement and improving family care might be helpful to improve MCS among this vulnerable population.

Association between social capital and mental health among older people living with HIV: the Sichuan Older HIV-Infected Cohort Study (SOHICS)

BACKGROUND

Mental health problems are common among older people living with HIV and associated with poorer health outcomes. Social capital is an important determinant of mental health problems but under-studied in this population. This study investigated the association between social capital and mental health problems among older people living with HIV in China.

METHODS

The study was based on the baseline data of a cohort study investigating mental health among older people living with HIV in Sichuan, China during November 2018 to February 2019. Participants were people living with HIV aged ≥50 years living in Sichuan province. Stratified multi-stage cluster sampling was used to recruit participants from 30 communities/towns; 529 out of 556 participants being approached completed the face-to-face interview. Social capital was measured by two validated health-related social capital scales: the Individual and Family scale and the Community and Society scale. Presence of probable depression (CES-D-10 score ≥ 10) and probable anxiety (GAD-7 score ≥ 5) were used as dependent variables. Two-level logistic regression models were applied to examine the association between social capital and probable depression/anxiety.

RESULTS

The prevalence of probable depression and probable anxiety was 25.9% (137/529) and 36.3% (192/529), respectively. After adjusting for significant covariates, the individual/family level of social capital was inversely associated with both probable depression (odds ratios (OR): 0.89, 95% CI: 0.84-0.93, p < 0.001) and probable anxiety (OR: 0.90, 95% CI: 0.86-0.95, p < 0.001). The community/society level social capital was associated with probable depression (OR: 0.91, 95% CI: 0.84-0.99, p < 0.001) but not probable anxiety (p > 0.05).

CONCLUSIONS

Interventions building up social capital should be considered to improve mental health of older people living with HIV. Some useful strategies include cognitive processing therapy, improving community networking and engagement, and promoting social bonding with neighborhood.

Early mortality after late initiation of antiretroviral therapy in the TREAT Asia HIV Observational Database (TAHOD) of the International Epidemiologic Databases to Evaluate AIDS (IeDEA) Asia-Pacific

OBJECTIVES

Early mortality among those still initiating antiretroviral therapy (ART) with advanced stages of HIV infection in resource-limited settings remains high despite recommendations for universal HIV treatment. We investigated risk factors associated with early mortality in people living with HIV (PLHIV) starting ART at low CD4 levels in the Asia-Pacific.

METHODS

PLHIV enrolled in the Therapeutics, Research, Education and AIDS Training in Asia (TREAT Asia) HIV Observational Database (TAHOD) who initiated ART with a CD4 count < 100 cells/μL between 2003 and 2018 were included in the study. Early mortality was defined as death within 1 year of ART initiation. PLHIV in follow-up for > 1 year were censored at 12 months. Competing risk regression was used to analyse risk factors with loss to follow-up as a competing risk.

RESULTS

A total of 1813 PLHIV were included in the study, of whom 74% were male. With 73 (4%) deaths, the overall first-year mortality rate was 4.27 per 100 person-years (PY). Thirty-eight deaths (52%) were AIDS-related, 10 (14%) were immune reconstituted inflammatory syndrome (IRIS)-related, 13 (18%) were non-AIDS-related and 12 (16%) had an unknown cause. Risk factors included having a body mass index (BMI) < 18.5 [sub-hazard ratio (SHR) 2.91; 95% confidence interval (CI) 1.60-5.32] compared to BMI 18.5-24.9, and alanine aminotransferase (ALT) ≥ 5 times its upper limit of normal (ULN) (SHR 6.14; 95% CI 1.62-23.20) compared to ALT < 5 times its ULN. A higher CD4 count (51-100 cells/μL: SHR 0.28; 95% CI 0.14-0.55; and > 100 cells/μL: SHR 0.12; 95% CI 0.05-0.26) was associated with reduced hazard for mortality compared to CD4 count ≤ 25 cells/μL.

CONCLUSIONS

Fifty-two per cent of early deaths were AIDS-related. Efforts to initiate ART at CD4 counts > 50 cell/μL are associated with improved short-term survival rates, even in those with late stages of HIV disease.

[Antimycotic therapy impact on oral mucosa Candida species composition in HIV-infected patients]

RESEARCH OBJECTIVES

the analysis of a specific and strains drift of Candida in HIV/AIDS patients with oropharyngeal candidiasis and the analysis of Candida sensitivity dynamics to reference antimycotic drugs. The study comprised 49 HIV-infected patients aged 20-69 years. The study revealed candidiasis treatment provides specific and strains drift of Candida. Eradication of fluconazole sensitive C. albicans leads to growth of more resistant strains (C. glabratae, krusei, tropicalis) thus lowering antimycotic therapy efficacy. The efficacy improvement requires selective approach to candidiasis treatment with azol agents.

Late Presentation and Missed Opportunities for HIV Diagnosis in Guatemala

Early HIV diagnosis remains a challenge in many regions with delayed diagnosis resulting in increased morbidity and mortality. We conducted a retrospective cohort study of people living with HIV receiving outpatient care at a large tertiary referral center in Guatemala to describe the proportion of late presenters (LP) and missed opportunities for HIV diagnosis. Of 3686 patients, 2990 (81.1%) were LP who were more likely to be male (60.2% vs. 48.0%, p < 0.0001), heterosexual (88.0% vs. 78.0%, p < 0.0001) and rural dwellers (43.7% vs. 33.8%. p < 0.0001). The proportions of patients who presented late or with AIDS at diagnosis decreased over time. Only 665 patients (18.2%) sought care in the 2 years prior to HIV diagnosis. This study, the first of its kind in Central America to focus on late presenters and missed opportunities for HIV diagnosis, demonstrates extremely high rates of LP in Guatemala. Although in recent years rates of LP have improved somewhat, the need for screening outside of traditional healthcare settings is apparent.
