Abstract

The potential for Plasmodium falciparum histidine-rich protein-2 (PfHRP-2) dipstick tests to predict antimalarial treatment failure was investigated in a prospective study in Thailand of 38 patients admitted with severe malaria and 54 hospitalized with uncomplicated P. falciparum infections. Of these, 40 had subsequent recrudescence of their infections. Overall, 89% of patients with severe malaria and 61% of patients with uncomplicated malaria had positive PfHRP-2 dipstick tests for > 2 weeks following the start of treatment. Persistence was correlated positively with admission parasite counts, PfHRP-2 intensity scores and disease severity. PfHRP-2 tests which remained positive for > 2 weeks and PfHRP-2 reactive intensity scores on admission, at day 7 and day 14 did not predict treatment failure independent of admission parasitaemia. Freezing and thawing the blood samples did not significantly affect PfHRP-2 results tested by the dipstick technique. The PfHRP-2 dipstick test provides a useful indicator of recent severe malaria, but does not predict the therapeutic response.

  • An important weakness of RDT-HRP2 tests is the prolonged half-life of HRP-2 antigen, which can be identified in plasma several weeks after parasite clearance and therefore cannot distinguish current from recent infection.

  • These shortcomings hinder the use of existing RDTs for managing malaria and for monitoring treatment efficacy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
