Low Levels of Human Antibodies to Gametocyte-Infected Erythrocytes Contrasts the PfEMP1-Dominant Response to Asexual Stages in P. falciparum Malaria

January 14, 2019

Vaccines that target Plasmodium falciparum gametocytes have the potential to reduce malaria transmission and are thus attractive targets for malaria control. However,…

Loss of complement regulatory proteins on uninfected erythrocytes in vivax and falciparum malaria anemia

November 15, 2018

Red blood cells destruction through loss of complement regulatory proteins (CRPs) is an immunopathogenic mechanism that contributes to malaria anaemia in Plasmodium falciparum. However, its role in P. vivax malaria is unknown. Our study showed CR1 and CD55 were reduced in severe anaemia in both falciparum and vivax malaria. The loss of CRPs however, was only restricted to uninfected RBCs, with infected RBCs having higher expressions. This study highlights the likely critical role of reduced CRPs expression on uninfected RBCs in falciparum and vivax malaria anaemia, and demonstrated that higher CRPs expression on infected RBCs may suggest parasite’s invasion and immune evasion strategy.

Multiple morbidities in pregnancy: Time for research, innovation, and action

September 25, 2018

Multimorbidity is a major issue affecting pregnant women globally. Infectious diseases (such as HIV, malaria, tuberculosis, and sexually transmitted infections [STIs]) together with NCDs that are increasingly common in LMICs as a result of demographic, socioeconomic, and environmental changes (cardiovascular disease, diabetes, anemia, micronutrient deficiencies, hypertension, and mental health challenges) each account for substantial morbidity in pregnancy. However, the burden of their combination is less well recognized, and the impacts are not well understood. In most malaria endemic populations, the burden of multimorbidities is very high such that malaria typically co-occurs with numerous other health problems and health risks. In this editorial, the authors call for greater investment in research, innovation, and translation to drive the development of new tools, interventions, and strategies, including greater investment in this are by the industry sector. They identify main priorities for research and innovation across levels of healthcare, and the need for workforce development and health system–patient–community partnerships for care and interventions across the spectrum of reproductive, maternal, and child health.
