Asymptomatic malaria parasitaemia and virological non-suppression among children living with HIV in Accra, Ghana: a cross-sectional study.
Article in Research square, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Human Immunodeficiency Virus (HIV) and malaria are two major diseases in sub-Saharan Africa, with coinfections having an impact on the outcomes of both. We assessed the association between asymptomatic malaria parasitaemia and virological non-suppression among children living with HIV attending a clinic at the Korle Bu Teaching Hospital (KBTH) and the Princess Marie Louis Hospital (PML) in the city of Accra, Ghana. Methods: This was a cross-sectional study of asymptomatic malaria in children receiving care at paediatric HIV clinics at KBTH and PML conducted from September to November 2022. Patients who had been on ART for at least 6 months were eligible to participate. Structured questionnaires were used to collect socio-demographic, malaria prevention behaviors, and ART-related data using in-person interviews. Microscopy and PCR were used to screen for malaria and GeneXpert to determine viral load. To examine the determinants of malaria PCR positivity and virological non-suppression, Chi-square tests and logistic regression were utilized. Results: The participants' median age was 9 years with a range of 6 to 12 years. Males made up 57% of the population. We detected 3.6% (10 of 277) and 7.6% (21 of 277) cases of malaria using microscopy and PCR, respectively. Virological non-suppression (VL > 1000 copies/ml) was seen in 82 (29.6%) of the 277 participants. Among the suppressed individuals, 62 (22.4%) exhibited low-level viraemia (VL level 40-1000 copies/ml) and 133 (48%) had non-detectable viral load levels. There were no factors associated with malaria PCR positivity carriage. Poor adherence to antiretroviral therapy was associated with a fivefold increase in the risk of viral load non-suppression (AOR = 4.89 [CI = 2.00-11.98], p = 0.001). Conclusion: The study showed that the proportion of children living with HIV with asymptomatic malaria parasitaemia was low, with about one third of the study population having virological non suppression. The interaction between malaria parasitemia and viral replication may not be the main culprit for virological non suppression.
