Identifying malaria control issues: a district hospital-based evaluation.(1995-12)Chuk district hospital is centrally located in a rural malarious region in southern Cambodia. It was the site of a hospital-based evaluation (KAP assessment and in vivo i.v. quinine/oral tetracycline drug study) done to identify relevant issues for establishing a rational malaria control strategy. The KAP assessment identified the young, male forest worker as the highest risk group. Of 112 study patients, 73% were male and 82% reported various forest activities. The primary reason found for patient delay (8.9 days) in seeking hospital care was self-treatment at home (N = 102, 91%) with drugs purchased through private sellers (104/105). Using the 7-day WHO field test methodology, resistance rates were calculated (N = 22); S1/R1, 73%; R1, 9%; R2, 0%; R3, 18%. A modified version of the 7-day test was used to calculate its utility in this particular rural setting. It showed a negative predictive value of 93% and a positive predictive value of 71%. The case fatality rate for the study period was 2.7%. Information from this study, which correlates a confirmed malaria diagnosis with prior patient behavior and response to anti-malarial therapy, is intended for realizing the goals set forth by the national malaria control program.
A randomized open study to assess the efficacy and tolerability of dihydroartemisinin-piperaquine for the treatment of uncomplicated falciparum malaria in Cambodia.(Wiley-Blackwell, 2007-02)OBJECTIVES: To compare the efficacy and tolerability of dihydroartemisinin-piperaquine (DHA-PQP) with that of a 3-day regimen of mefloquine and artesunate (MAS3) for the treatment of uncomplicated falciparum malaria in Cambodia. METHOD: Randomized open-label non-inferiority study over 64 days. RESULTS: Four hundred and sixty-four patients were included in the study. The polymerase chain reaction genotyping-adjusted cure rates on day 63 were 97.5% (95% confidence interval, CI, 93.8-99.3) for DHA-PQP and 97.5% (95% CI, 93.8-99.3) for MAS3, P = 1. There were no serious adverse events, but significantly more episodes of vomiting (P = 0.03), dizziness (P = 0.002), palpitations (P = 0.04), and sleep disorders (P = 0.03) reported in the MAS3 treatment group, consistent with the side-effect profile of mefloquine. CONCLUSIONS: DHA-PQP was as efficacious as MAS3, but much better tolerated, making it more appropriate for use in a routine programme setting. This highly efficacious, safe and more affordable fixed-dose combination could become the treatment of choice for Plasmodium falciparum malaria in Cambodia.
