A programmatic assessment of dolutegravir adverse events and discontinuations in Uganda.

Introduction: Dolutegravir is now extensively used in sub-Saharan Africa as a preferred component of antiretroviral therapy (ART). There is a paucity of large studies using routinely collected data from African people living with HIV on dolutegravir-based regimens to inform HIV programmes. We reviewed data in a large programme clinic of people living with HIV on dolutegravir to determine the real-world safety and tolerability of dolutegravir and to describe drivers of treatment discontinuation.

Pulmonary granuloma formation during latent infection in C3HeB/FeJ mice involves progression through three immunological phases.

is a fungal pathogen that can cause lethal disease in immunocompromised patients. Immunocompetent host immune responses, such as formation of pulmonary granulomas, control the infection and prevent disseminated disease. Little is known about the immunological conditions establishing the latent infection granuloma in the lungs.

The evolution of HIV-associated cryptococcal meningitis in Uganda from 2010 to 2022.

Given extensive improvements in access to antiretroviral therapy (ART) over the past 12 years, the HIV and cryptococcal meningitis landscapes have dramatically changed since 2010. We sought to evaluate changes in clinical presentation and clinical outcomes of people presenting with HIV-associated cryptococcal meningitis between 2010 and 2022 in Uganda. We analyzed three prospective cohorts of HIV-infected Ugandans with cryptococcal meningitis during 2010-2012, 2013-2017, and 2018-2022.

Single nucleotide polymorphisms are associated with strain-specific virulence differences among clinical isolates of Cryptococcus neoformans.

Studies across various pathogens highlight the importance of pathogen genetic differences in disease manifestation. In the human fungal pathogen Cryptococcus neoformans, sequence type (ST) associates with patient outcome. We performed a meta-analysis of four genomic studies and identified overlapping gene regions associated with virulence, suggesting the importance of these gene regions in cryptococcal disease in diverse clinical isolates.

Virulence-associated variants in sequence type 93 are less likely to be associated with population structure compared to independent rare mutations.

is a pathogenic yeast that is the causative agent of cryptococcal meningitis. While it is well known that the genotype of impacts patient outcomes, the reason for this association has not been well elucidated. In this study, we examined the relationship between two subpopulations in the sequence type 93 clade of : ST93A and ST93B.

Effectiveness of interactive voice response-call for life mHealth tool on adherence to anti-retroviral therapy among young people living with HIV: A randomized trial in Uganda.

Introduction: In people living with HIV, adherence to antiretroviral therapy (ART) is essential for achieving and sustaining viral suppression and reducing mortality. In young people living with HIV, ART adherence and retention remain a challenge with unsatisfactory viral suppression rates despite facility-based intensive adherence counseling that is the standard of care. Few studies have evaluated mHealth adherence interventions among young people living with HIV in resource-limited settings.

Clinical importance of cerebrospinal fluid protein levels in HIV-associated cryptococcal meningitis: Insights from a prospective cohort study in Uganda.

Cerebrospinal fluid (CSF) protein levels exhibit high variability in HIV-associated cryptococcal meningitis; however, its clinical implications remain unclear. We analyzed data from 890 adults with HIV-associated cryptococcal meningitis randomized into two clinical trials in Uganda between 2015 and 2021. CSF protein was grouped into < 100 mg/dl (72%, n = 641) and ≥ 100 mg/dl (28%, n = 249).

Primary treatment of chronic pulmonary aspergillosis with weekly liposomal amphotericin B: A case report from Uganda.

Chronic pulmonary aspergillosis (CPA) treatment in Africa remains unexplored. We present a 23-year-old Ugandan male, previously treated thrice for pulmonary tuberculosis, developing CPA. Imaging showed lung fibrosis, bronchiectasis, and a fungal ball.

Prevalence and factors associated with hyperglycemia among persons living with HIV/AIDS on dolutegravir-based antiretroviral therapy in Uganda.

Background: Dolutegravir-based (DTG) regimens are rapidly becoming the preferred first-line antiretroviral therapy (ART) for people living with HIV (PLHIV) in low and middle-income countries. However, there are rising concerns over the development of hyperglycemia and, in some cases, diabetes mellitus in patients switched to DTG.

Objectives: To determine the prevalence and factors associated with hyperglycemia among PLHIV receiving DTG-based ART at Kiruddu National Referral Hospital (KNRH), Uganda.

Evolution of Laboratory Diagnostics for Cryptococcosis and Missing Links to Optimize Diagnosis and Outcomes in Resource-Constrained Settings.

Cryptococcal meningitis is one of the leading causes of death in sub-Saharan Africa among patients with advanced HIV disease. Early diagnosis is crucial in improving treatment outcomes. Despite advances and the availability of modern and point-of-care diagnostics for cryptococcosis, gaps still exist in resource-constrained settings, leading to unfavorable treatment outcomes.

Implementation of single high-dose liposomal amphotericin B based induction therapy for treatment of HIV-associated cryptococcal meningitis in Uganda: a comparative prospective cohort study.

Background: In 2022, the World Health Organization (WHO) recommended a single 10mg/kg dose of liposomal amphotericin B in combination with 14 days of flucytosine and fluconazole (AMBITION-cm regimen) for induction therapy of HIV-associated cryptococcal meningitis, based on the results of the multisite AMBITION-cm trial. We evaluated outcomes after real-world implementation of this novel regimen in Uganda.

Methods: We enrolled Ugandan adults with cryptococcal meningitis into an observational cohort receiving the AMBITION-cm regimen with therapeutic lumbar punctures in routine care during 2022-2023.

Health-related quality of life and hypertension in people with HIV on long-term antiretroviral therapy in Uganda.

Introduction: The presence of hypertension could reduce the health-related quality of life (HRQoL) of people with HIV (PWH). Yet, literature describing the HRQoL of PWH who have hypertension in Uganda is scarce making the design of locally adapted interventions cumbersome. In our study, we compared HRQoL scores of people with HIV with and without hypertension on long term antiretroviral therapy (ART) in Uganda.

Comparison of early fungicidal activity and mortality between daily liposomal amphotericin B and daily amphotericin B deoxycholate among patients with HIV-associated cryptococcal meningitis.

Background: Limited data exist on the antifungal activity of daily liposomal amphotericin B with flucytosine induction regimens for cryptococcal meningitis, which are recommended in high-income countries. Liposomal amphotericin B monotherapy at 3 mg/kg previously failed to meet non-inferiority criteria compared to amphotericin B deoxycholate in its registrational clinical trial. We aimed to compare the quantitative antifungal activity and mortality between daily amphotericin B deoxycholate and daily liposomal amphotericin among persons with HIV-related cryptococcal meningitis receiving adjunctive flucytosine 100 mg/kg/day.
