“Presumptive treatment” without the benefit of laboratory confirmation should be reserved for extreme circumstances (strong clinical suspicion or severe disease in a setting where prompt laboratory diagnosis is not available). Once the diagnosis of malaria has been made, appropriate antimalarial treatment must be initiated immediately.

Introduction The first indication that Plasmodium vivax might be developing resistance to chloroquine in Papua New Gui- nea was the failure of an 8 months old infant to respond adequately to treatment with chloroquine SCHUURKAMP et al. 1989. Chloroquine has been used as the first-line treatment for Plasmodium vivax since 1946 1. Treatment failure of chloroquine in P. vivax has, however, been increasing in some malaria endemic countries. The resistance was first reported in Papua New Guinea 2, and was subsequently reported in several countries in Asia 3 - 8. Although Plasmodium falciparum often takes the spotlight, given its more severe course. Chloroquine has long been the drug offered to patients with unconfirmed malaria and those diagnosed with P vivax infection. Given the rise of drug resistance in many infectious agents due to poorly regulated drug use, it is no surprise that resistance has occurred in the organism that so frequently infects us. The clinical status of the patient: Patients diagnosed with malaria are generally categorized as having either uncomplicated or severe malaria. Treatment should be guided by three main factors: infections, the urgent initiation of appropriate therapy is especially critical.

Chloroquine has remained the drug of choice for the prophylaxis and treatment of P vivax. We now report vivax malaria in 2 soldiers who were taking weekly chloroquine and pyrimethamine/dapsone 'Maloprim' prophylaxis. PLASMODIUM VIVAX RESISTANCE TO CHLOROQUINE? - ScienceDirect. Chloroquine-resistant Plasmodium vivax in Pakistan an.. PDF Chloroquine-resistant Plasmodium vivax. Oct 29, 2008 Plasmodium vivax accounts for about 40% of all malaria infection in Ethiopia. Chloroquine CQ is the first line treatment for confirmed P. vivax malaria in the country. The first report of CQ treatment failure in P. vivax was from Debre Zeit, which suggested the presence of chloroquine resistance. There was marked heterogeneity in the design of the clinical studies assessing the efficacy of chloroquine towards P. vivax. Patients receiving chloroquine plus primaquine had an equivalent or lower risk of P. vivax recurrence by day 28 compared with patients receiving chloroquine alone. Overall P. vivax was defined as chloroquine resistant for more than half of the 122 sites where efficacy could be assessed. Delayed parasite clearance was predictive of early recurrence. Chloroquine remains the mainstay of treatment for Plasmodium vivax malaria despite increasing reports of treatment failure. We did a systematic review and meta-analysis to investigate the effect of chloroquine dose and the addition of primaquine on the risk of recurrent vivax malaria across different settings.
