Human genetic variants can affect TB and HIV drug metabolism, which may lead to toxicity or treatment failure. We evaluated associations between genetic variants of antiretroviral therapy (ART) and HIV-1 outcomes among TB/HIV patients. We included RePORT-Brazil participants with TB/HIV who initiated standard TB treatment [2 months of isoniazid/rifampicin (or rifabutin)/pyrazinamide/ethambutol, then 4 months or more of isoniazid/rifampicin (or rifabutin)], and ART.

The impact of human pulmonary tuberculosis (TB) on the bioenergetic metabolism of circulating immune cells remains elusive, as does the resolution of these effects with TB treatment. In this study, the rates of oxidative phosphorylation (OXPHOS) and glycolysis in circulating lymphocytes and monocytes of patients with drug-susceptible TB at diagnosis, 2 months, and 6 months during treatment, and 12 months after diagnosis were investigated using extracellular flux analysis. At diagnosis, the bioenergetic parameters of both blood lymphocytes and monocytes of TB patients were severely impaired in comparison to non-TB and non-HIV-infected controls.

HIV care continuum outcome disparities by health insurance status have been noted among people with HIV (PWH). We therefore examined associations between state Medicaid expansion and HIV outcomes in the United States. Adults (≥18 years) with ≥1 visit in NA-ACCORD clinical cohorts from 2012-2017 contributed person-time annually between first and final visit or death; in each calendar year, clinical retention was ≥2 completed visits > 90 days apart, antiretroviral therapy (ART) receipt was receipt of ≥3 antiretroviral agents, and viral suppression was last measured HIV-1 RNA < 200 copies/mL.

Article Synopsis
  • TB treatment response varies based on genetic ancestry, with a study in Brazil showing differing risks for adverse drug reactions (ADRs) linked to African and European ancestry.
  • Patients with a higher proportion of African ancestry had a lower risk of Grade 2+ ADRs, while those with higher European ancestry faced an increased risk; however, this trend changed for patients living with HIV.
  • The research involved 941 pulmonary TB patients, and no significant associations were found for Amerindian ancestry or other treatment outcomes in the cohort.

Article Synopsis
  • The study established new therapeutic drug ranges (TDR) for standard anti-tuberculosis (TB) drugs aimed at minimizing toxicity while maximizing effectiveness in treating TB.
  • It analyzed data from 448 patients with drug-susceptible pulmonary TB, identifying drug concentrations that maintained a low probability of adverse drug reactions (ADR) and a high probability of treatment success.
  • Findings revealed that the TDR for isoniazid (INH) and rifampin (RIF) were different from current recommendations, suggesting higher upper limits for INH and lower for RIF, while the ranges for ethambutol (EMB) and pyrazinamide (PZA) were consistent with existing guidelines.

Article Synopsis
  • The study aimed to evaluate how well the Veterans Aging Cohort Study (VACS) Index 2.0 predicts specific causes of death in people with HIV (PWH) receiving antiretroviral therapy (ART), which could improve targeted healthcare interventions.
  • It involved analyzing data from over 59,000 PWH who started ART between 2000 and 2018, calculating their VACS scores and examining the relationship between these scores and causes of death through various statistical models.
  • Findings revealed that the VACS Index 2.0 was particularly effective at predicting deaths from AIDS-related causes and other measurable health issues, but less reliable for predicting suicides or accidental deaths.

Background: Since 2014, Brazil has gradually implemented the Xpert MTB/RIF (Xpert) test to enhance early tuberculosis (TB) and drug-resistant (DR-TB) detection and control, yet its nationwide impact remains underexplored. Our study conducts an intervention time-series analysis (ITSA) to evaluate how the Xpert's implementation has improved TB and DR-TB detection nationwide.

Methods: 1,061,776 cases from Brazil's National TB Registry (2011-2022) were reviewed and ITSA (2011-2019) was used to gauge the impact of the Xpert's adoption on TB and DR-TB notification.

Background: Identifying patients at increased risk of loss to follow-up (LTFU) is key to developing strategies to optimize the clinical management of tuberculosis (TB). The use of national registry data in prediction models may be a useful tool to inform healthcare workers about risk of LTFU. Here we developed a score to predict the risk of LTFU during anti-TB treatment (ATT) in a nationwide cohort of cases using clinical data reported to the Brazilian Notifiable Disease Information System (SINAN).
