Resum

BACKGROUND: The diagnosis of malaria during pregnancy is complicated by placental sequestration, asymptomatic infection, and low-density peripheral parasitaemia. Where intermittent preventive treatment (IPT) with sulfadoxine-pyrimethamine is threatened by drug resistance, or is inappropriate due to low transmission, intermittent screening and treatment (ISTp) with rapid diagnostic tests for malaria (RDT) could be a valuable alternative. Therefore, the accuracy of RDTs to detect peripheral and placental infection was assessed in a declining transmission setting in Papua New Guinea (PNG). METHODS: The performance of a combination RDT detecting histidine-rich protein-2 (HRP-2) and Plasmodium lactate dehydrogenase (pLDH), and light microscopy (LM), to diagnose peripheral Plasmodium falciparum and Plasmodium vivax infections during pregnancy, were assessed using quantitative real-time PCR (qPCR) as the reference standard. Participants in a malaria prevention trial in PNG with a haemoglobin 50 % of these infections. CONCLUSIONS: In PNG, HRP-2/pLDH RDTs may be useful to diagnose peripheral P. falciparum infections in symptomatic pregnant women. However, they are not sufficiently sensitive for use in intermittent screening amongst asymptomatic (anaemic) women. These findings have implications for the management of malaria in pregnancy. The adverse impact of infections undetected by RDT or LM on pregnancy outcomes needs further evaluation.
