Leprosy.

Leprosy, a neglected tropical disease, causes significant morbidity in marginalized communities. Before the COVID-19 pandemic, annual new case detection plateaued for over a decade at ~200,000 new cases. The clinical phenotypes of leprosy strongly parallel host immunity to its causative agents Mycobacterium leprae and Mycobacterium lepromatosis.

A global chromoblastomycosis strategy and development of the global chromoblastomycosis working group.

Chromoblastomycosis, an implantation mycosis, is a neglected tropical disease that causes decreased quality of life, stigma, and disability. The global burden of disease is unknown and data on disease epidemiology and outcomes are severely limited by a lack of access to needed diagnostic tools and therapeutics. The World Health Organization outlined targets for chromoblastomycosis in the Road Map for Neglected Tropical Diseases 2021-2030, but little progress has been made in initiating and implementing an effective control program globally.

Metformin as adjunctive therapy in combination with multidrug treatment for multibacillary leprosy: A protocol for a randomized double-blind, controlled Phase 2 trial in Indonesia (MetLep Trial).

Background: The clinical management of leprosy is complicated by leprosy reactions (LR) causing irreversible nerve damage and disabilities. LR often require long-term use of corticosteroids causing serious side effects. Adjunct host-directed therapy (HDT) is a potentially attractive strategy in leprosy to prevent LR and associated immunopathology, modulate immunological memory that protects against recurrence, and thereby reduce nerve damage, disability and corticosteroid-associated morbidities.

Teledermatology to Improve Access to and Quality of Skin Care in Eastern Indonesia.

Skin diseases are a major public health concern in Indonesia, although access to specialized care in remote areas is limited. We initiated a low-cost teledermatology service in Sumba, a remote island in eastern Indonesia. Eighteen healthcare workers (HCWs) at five primary healthcare centers received training to manage common skin diseases and submit clinical cases beyond their expertise to an online platform.

The unbreakable journey: using photovoice to raise awareness and fight leprosy stigma in Papua, Indonesia.

In preparation of an ongoing trial to improve the treatment of leprosy (MetLep, clinicaltrials.gov: NCT05243654), we conducted a photovoice project among persons affected by leprosy in eastern Indonesia. Photovoice is a participatory visual method in which photographic images are used to explore community health and social issues among disadvantaged populations.

With Bare Feet in the Soil: Podoconiosis, a Neglected Cause of Tropical Lymphoedema.

Podoconiosis is a form of lymphoedema that occurs in tropical highland areas in genetically susceptible individuals who are exposed to irritant volcanic soils. The disease is preventable through consistent use of footwear and attention to foot hygiene; however, in endemic areas there is a strong barefoot tradition, and many cannot afford shoes. Patients with podoconiosis face significant physical disability, psychological comorbidity, reduced quality of life and experience frequent episodes of systemic illness due to acute dermatolymphangioadenitis.

Cell-associated HIV-1 RNA predicts viral rebound and disease progression after discontinuation of temporary early ART.

Plasma viral load (VL) and CD4+ T cell count are widely used as biomarkers of HIV type 1 (HIV-1) replication, pathogenesis, and response to antiretroviral therapy (ART). However, the clinical potential of cell-associated (CA) HIV-1 molecular markers is much less understood. Here, we measured CA HIV-1 RNA and DNA in HIV-infected individuals treated with temporary ART initiated during primary HIV-1 infection.

Effect of antiretroviral therapy on bone turnover and bone mineral density in men with primary HIV-1 infection.

Introduction: Previous studies indicate that human immunodeficiency virus (HIV)-infection and combination antiretroviral therapy (cART) can affect bone turnover. Furthermore, HIV-infected patients have lower bone mineral density (BMD) compared to a healthy reference population.

Objective: To evaluate the longitudinal effect of HIV-infection and cART on bone turnover markers (BTMs) and BMD in men with primary HIV-infection (PHI).

Longitudinal dynamics of the HIV-specific B cell response during intermittent treatment of primary HIV infection.

Background: Neutralizing antibodies develop in natural HIV-1 infection. Their development often takes several years and may rely on chronic virus exposure. At the same time recent studies show that treatment early in infection may provide opportunities for immune preservation.

Juvenile dermatomyositis in a 4-year-old Kenyan girl.

To our knowledge, this is the first case report of juvenile dermatomyositis (JDM) in Tanzania. It demonstrates that the characteristic cutaneous findings of JDM may easily be overlooked, especially on dark skin, and the difficulty of clinical management in resource-constrained settings.

A lower viral set point but little immunological impact after early treatment during primary HIV infection.

The Primo-SHM trial, a multicenter randomized trial comparing no treatment with 24 or 60 weeks of combination antiretroviral therapy (cART) during primary human immunodeficiency virus (HIV) infection (PHI), recently demonstrated that temporary early cART lowered the viral set point and deferred the need for re-initiation of cART during chronic HIV infection. This study examined whether the beneficial effect of early treatment was caused by preservation of immunological responses. Twenty-seven treated and 20 untreated PHI individuals participating in the Primo-SHM trial were compared at viral set point, that is, 36 weeks after baseline or after treatment interruption, respectively, for a diverse set of immunological parameters.

Temporary treatment during primary HIV infection does not affect virologic response to subsequent long-term treatment.

Temporary cART during primary HIV-infection (PHI) did not select for drug resistance mutations after treatment interruption and did not affect the subsequent virological response to long-term cART. Our data demonstrate that fear of drug resistance development is not a valid argument to refrain from temporary early treatment during PHI.

Low bone mineral density, regardless of HIV status, in men who have sex with men.

A high prevalence of low bone mineral density (BMD) has been reported among men with primary or chronic human immunodeficiency virus (HIV) infection. To gain further insight into the contribution of HIV infection, we compared the BMD of 41 men who have sex with men (MSM) with primary HIV infection, 106 MSM with chronic HIV infection, and a control group of 30 MSM without HIV infection. Low BMD, defined as a z score of ≥ 2.

No advantage of quadruple- or triple-class antiretroviral therapy as initial treatment in patients with very high viraemia.

Background: We assessed whether quadruple or triple-class therapy for the initial treatment of HIV-1 infection provides a virological benefit over standard triple therapy in patients with very high plasma viraemia. The assessment was made based on a national observational HIV cohort in the Netherlands.

Methods: Inclusion criteria were age ≥18 years, treatment-naive, plasma viral load (pVL) ≥500,000 copies/ml and initiation of quadruple or triple therapy between 2001 and 2011.

No treatment versus 24 or 60 weeks of antiretroviral treatment during primary HIV infection: the randomized Primo-SHM trial.

Background: The objective of this study was to assess the benefit of temporary combination antiretroviral therapy (cART) during primary HIV infection (PHI).

Methods And Findings: Adult patients with laboratory evidence of PHI were recruited in 13 HIV treatment centers in the Netherlands and randomly assigned to receive no treatment or 24 or 60 wk of cART (allocation in a 1∶1∶1 ratio); if therapy was clinically indicated, participants were randomized over the two treatment arms (allocation in a 1∶1 ratio). Primary end points were (1) viral set point, defined as the plasma viral load 36 wk after randomization in the no treatment arm and 36 wk after treatment interruption in the treatment arms, and (2) the total time that patients were off therapy, defined as the time between randomization and start of cART in the no treatment arm, and the time between treatment interruption and restart of cART in the treatment arms.

HIV-1 dual infection is associated with faster CD4+ T-cell decline in a cohort of men with primary HIV infection.

Background:  In vitro, animal, and mathematical models suggest that human immunodeficiency virus (HIV) co- or superinfection would result in increased fitness of the pathogen and, possibly, increased virulence. However, in patients, the impact of dual HIV type 1 (HIV-1) infection on disease progression is unclear, because parameters relevant for disease progression have not been strictly analyzed. The objective of the present study is to analyze the effect of dual HIV-1 infections on disease progression in a well-defined cohort of men who have sex with men.

A Case of Kaposi's Sarcoma during Primary HIV-1 Infection.

The majority of cases of Kaposi's sarcoma (KS) occur at low CD4 counts during chronic HIV-1 infection. We present a case of KS which was diagnosed during primary HIV-1 infection. This report aims to draw attention that KS may occur early in the course of HIV-1 infection and that primary HIV-1 infection may rapidly progress to AIDS.

Activity of broadly neutralizing antibodies, including PG9, PG16, and VRC01, against recently transmitted subtype B HIV-1 variants from early and late in the epidemic.

For the development of a neutralizing antibody-based human immunodeficiency virus type 1 (HIV-1) vaccine, it is important to characterize which antibody specificities are most effective against currently circulating HIV-1 variants. We recently reported that HIV-1 has become more resistant to antibody neutralization over the course of the epidemic, and we here explore whether this increased neutralization resistance is also observed for the newly identified broadly neutralizing antibodies (BrNAbs) PG9, PG16, and VRC01. Furthermore, we performed a comprehensive analysis of the neutralizing sensitivity of currently circulating recently transmitted subtype B viruses to the currently most known BrNAbs.
