Severe malarial anemia (MA) is the primary manifestation of severe malaria among children in areas of holoendemic Plasmodium falciparum transmission. Although overproduction of inflammatory-derived cytokines are implicated in the immunopathogenesis of severe MA, chemokines such as regulated on activation, normal T-cell expressed and secreted (RANTES, CCL5) are largely unexplored in childhood malaria. We found that RANTES is decreased during severe MA (p<0.01), and associated with suppression of erythropoiesis (p<0.05) and malaria-induced thrombocytopenia (p<0.05). These findings suggest that thrombocytopenia may be a source of reduced RANTES which may contribute, at least in part, to suppression of erythropoiesis in children with malarial anemia.

Background: The frequent communication between African and Southeast Asian (SEA) countries has led to the risk of imported malaria cases in the China-Myanmar border (CMB) region. Therefore, tracing the origins of new malaria infections is important in the maintenance of malaria-free zones in this border region. A new genotyping tool based on a robust mitochondrial (mt) /apicoplast (apico) barcode was developed to estimate genetic diversity and infer the evolutionary history of Plasmodium falciparum across the major distribution ranges.

Article Synopsis
- Malaria has surged in sub-Saharan Africa due to disruptions from the Covid-19 pandemic, leading to severe cases like cerebral malaria and acute kidney injury.
- A 22-year-old male from Chad, who presented with confusion and had a history of travel to an endemic area, was initially misdiagnosed but later confirmed to have malaria with severe symptoms.
- Successful treatment included intravenous artesunate and hemodialysis, and the patient was discharged after 20 days, highlighting the need for quick diagnosis and effective management of malaria complications.

malaria affects millions of people in certain regions of the world, with neurological involvement and/or cerebral malaria as potential manifestations. Brain magnetic resonance imaging (MRI) abnormalities have been well-documented in cerebral malaria. However, MRI abnormalities in non-cerebral malaria, especially in neurologically asymptomatic patients, are not well understood and have been less frequently reported, especially in non-endemic regions.
