Prevalence of the molecular marker of chloroquine resistance (pfcrt 76) in Nigeria 5 years after withdrawal of the drug as first-line antimalarial: A cross-sectional study
Methods. We monitored the resistance pattern 5 years after withdrawal of CQ, using the pfcrt K76T mutation as a molecular marker for CQ resistance.
Results. Of 98 Plasmodium falciparum-positive blood samples, 95 (96.9%) showed the K76T mutation. Twenty-seven (27.6%) of the children had been treated with CQ at home before presentation at the clinic, while 50 (51.0%) had taken other antimalarials.
Conclusion. Our results indicate that there is an urgent need to re-evaluate antimalarial drug policy in Nigeria, especially when 27.6% of our study population still use CQ at home despite its withdrawal as first-line antimalarial. This may require effective legislation against the manufacture, importation and use of CQ in Nigeria, if the purpose behind its withdrawal is to be achieved.
