Between January 1998 and December 2000, the Jayapura Provincial Public Hospital in northeastern Indonesian New Guinea (Papua) admitted 5,936 patients with a diagnosis of malaria. The microscopic diagnosis at admission was Plasmodium falciparum (3,976, 67%), Plasmodium vivax (1,135, 19%), Plasmodium malariae (8, < 1%), and mixed species infections (817, 14%). Approximately 9% (367) of patients w...

The contribution of mannose-binding lectin (MBL) to protection from malaria was assessed by comparing plasma concentrations of MBL and the frequency of MBL gene polymorphisms in groups of Gabonese children participating in a prospective study of severe and mild malaria due to infection with Plasmodium falciparum. At admission, a higher proportion of patients with severe malaria had a low level ...

OBJECTIVES To determine whether sequestration of parasitized red blood cells differs between children with uncomplicated and severe Plasmodium falciparum malaria. METHODS We quantified circulating-, total- and sequestered-parasite biomass, using a mathematical model based on plasma concentration of P. falciparum histidine rich protein 2, in Gambian children with severe (n = 127) and uncomplic...

INTRODUCTION Malaria is a preventable and curable disease. Mazowe district had been experiencing a lower malaria transmission rate in comparison to other districts in the Mashonaland Central province but it experienced a huge outbreak in the 2013-2014 rainy seasons with a case fatality rate (CFR) of 0.21%. This CFR was the highest in the province and it was twice as much as the national CFR (0....

BACKGROUND Malaria is still a major health problem in some parts of the world. Plasmodium falciparum is the common pathogenic parasite and is responsible for majority of malaria associated deaths. Recently the other benign parasite, P. vivax, is reported to cause life threatening severe malaria complications. Thus, this study was aimed to assess incidence of severe malaria symptoms caused by P....

BACKGROUND Severe malaria is a leading cause of childhood mortality in Africa. However, at presentation, it is difficult to predict which children with severe malaria are at greatest risk of death. Dysregulated host inflammatory responses and endothelial activation play central roles in severe malaria pathogenesis. We hypothesized that biomarkers of these processes would accurately predict outc...

Within the human host, the malaria parasite Plasmodium falciparum is exposed to multiple selection pressures. The host environment changes dramatically in severe malaria, but the extent to which the parasite responds to-or is selected by-this environment remains unclear. From previous studies, the parasites that cause severe malaria appear to increase expression of a restricted but poorly defin...

OBJECTIVE Studies on malaria due to co-existent P. falciparum and P. vivax infections are negligible in India. Therefore, this study was undertaken to find out the clinical profile, prognostic factors, and outcome of mixed species malaria and to compare it with P. falciparum malaria. METHODS This prospective, comparative study has been conducted in a tertiary health care institution with high...

Malaria infection induces oxidative stress in the host cells. Antioxidant enzymes such as glutathione S-transferases (GSTs) are responsible for fighting reactive oxygen species and reduction of oxidative stress. Common GST polymorphisms have been associated with susceptibility to different diseases whose pathologies involve oxidative stress. In this study, we tested the hypothesis that GST poly...

The simian parasite Plasmodium knowlesi causes severe human malaria; the optimal treatment remains unknown. We describe the clinical features, disease spectrum, and response to antimalarial chemotherapy, including artemether-lumefantrine and artesunate, in patients with P. knowlesi malaria diagnosed by PCR during December 2007-November 2009 at a tertiary care hospital in Sabah, Malaysia. Fifty-...
