Glucose-6-phosphate Dehydrogenase Variants: Analysing in Indian Plasmodium vivax Patients.
Article in Acta parasitologica, 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
purposePrimaquine (PQ) is recommended for radical cure of Plasmodium vivax (Pv) malaria, but its utilization is still limited due to high risk of severe haemolytic anaemia in patients with glucose-6-phosphate dehydrogenase deficiency (G6PD-d). The aim of the present study is to assess the different genotypic variants leading to G6PD-d in Delhi and Goa regions of India.
methodsA total of 46 samples (34 retrospective Pv-mono-infected samples and 12 Pv-uninfected samples) were included in the study. Various genetic variants leading to G6PD-d were analysed by PCR amplification and DNA sequencing of different targeted exons of G6PD gene.
resultsMolecular analysis showed presence of four mutations in study population viz. 1311 C > T, 34.1% & IVSXI 93T > C, 45.5% and two novel mutations 1388G > T, 2.3% and 1398 C > T, 2.3% (silent mutation). The bioinformatics and computational analysis demonstrate that the slight conformational changes caused by R643L mutation in protein are deleterious in nature.
conclusionThe observed mutations do not clarify the role or association between G6PD-d and Pv-infected cases. Further investigation is required in order to fully comprehend and analyse the precise role of these mutations with context to malaria infections.
