HIV and malaria are associated with immunological perturbations and neurocognitive disorders even when asymptomatic. However, the effect of asymptomatic malaria (AM) in HIV-infected adults on neurocognitive impairment (NCI) is not well understood. This study investigated the biomarkers of systemic inflammation and neurocognition in dually-infected Nigerian adults.
Dihydroartemisinin-piperaquine (DHA-PQ) provides highly effective therapy and chemoprevention for malaria in pregnant African women. PQ concentrations >10.3 ng/mL have been associated with reduced maternal parasitemia, placental malaria and improved birth outcomes. We characterized the population pharmacokinetics (PK) of PQ in a post-hoc analysis of human immunodeficiency virus (HIV)-infected and -uninfected pregnant women receiving DHA-PQ as chemoprevention every 4 or 8 weeks.
In The Lancet Global Health, Alexandra Hogan and colleagues1 report the findings of a modelling study in which they estimate the number of excess deaths from HIV, tuberculosis, and malaria that could plausibly occur as a consequence of the COVID-19 pandemic.
Lung cancer is one of the deadliest cancers worldwide due to chemoresistance in patients with late-stage disease. Quinoline derivatives show biological activity against HIV, malaria, bacteriuria, and cancer. DFIQ is a novel synthetic quinoline derivative that induces cell death in both in vitro and in vivo zebrafish xenograft models. DFIQ induced cell death, including apoptosis, and the IC50 values were 4.16 and 2.31 μM at 24 and 48 h, respectively.
HIV infection is associated with more frequent and severe episodes of malaria and may be the result of altered malaria-specific B cell responses. However, it is poorly understood how HIV and the associated lymphopenia and immune activation affect malaria-specific antibody responses.
Providing regular external quality assessment of primary level laboratories and timely feedback is crucial to ensure the reliability of testing capacity of the whole laboratory network.
