Malaria caused by Plasmodium vivax is a highly prevalent infection world-wide, that was previously considered mild, but complications such as anemia have been highly reported in the past years. In mice models of malaria, anti-phosphatidylserine (anti-PS) autoantibodies, produced by atypical B-cells, bind to uninfected erythrocytes and contribute to anemia. In human patients with P. falciparum malaria, the levels of anti-PS, atypical B-cells and anemia are strongly correlated to each other.
Asymptomatic malaria and anemia during pregnancy increase the risk of negative birth outcomes. This cross-sectional study investigated the prevalence and correlates of asymptomatic malaria and anemia during first antenatal care (ANC) visit among pregnant women in a rural district, Tanzania. HIV-uninfected pregnant women without symptoms of malaria (n = 819) attending their first ANC at Kibiti Health Centre were enrolled from February 2017 to February 2018.
One of the most important problems in controlling malaria is the limited access to effective and accurate diagnosis of malaria parasitemia. In the Democratic Republic of Congo (DRC), malaria is one of the leading causes of morbidity and mortality. The purpose of this study was to assess the prevalence of anemia and the relationship with asymptomatic submicroscopic Plasmodium infection.
Autoantibodies play an important role in the destruction of non-infected red blood cells (nRBCs) during malaria. However, the relationship between this clearance and ABO blood groups is yet to be fully enlightened, especially for Plasmodium vivax infections. Here we show that anti-RBC IgG and IgM are increased in anemic patients with acute vivax malaria.
In tropical areas of developing countries, the interactions among parasitic diseases such as soil-transmitted helminths (STHs) and malaria, and glucose-6-phosphate dehydrogenase deficiency (G6PDd), are complex. Here, we investigated their interactions and impact on anemia in school students residing in a conflict zone of northeast Myanmar. A cross-sectional survey was conducted between July and December 2015 in two schools located along the China–Myanmar border.
Parenteral artesunate for the treatment of severe malaria in non-immune travelers is associated with late-onset hemolysis. In children in sub-Saharan Africa, the hematologic effects of malaria and artesunate are less well documented. Here we report a prospective case series of 91 children with severe malaria treated with parenteral artesunate, managed at a resource-poor hospital in Africa, with longitudinal data on hemoglobin (Hb), lactate dehydrogenase (LDH), haptoglobin, and erythrocyte morphology.
Data were used that had been previously collected by Médecins Sans Frontières India for 1222 pregnant women residing in adjoining forest villages who attended one of seven mobile prenatal-care clinics between January 1 and December 31, 2012.
To evaluate the association between recommended preventative SP programs in pregnancy and low birth weight (LBW) and maternal anemia through available clinical trial, observational, and programmatic evaluation studies.
