Chloroquine Resistant Plasmodium falciparum in Nigeria

This study was designed to evaluate the association between polymorphisms in pfcrt and pfmdr1 genes and in-vitro chloroquine (CQ) sensitivity in fresh isolates of P. falciparum and patients’ treatment outcome. The modified schizont inhibition assay was used to determine in-vitro sensitivity of P. falciparum. Polymorphisms in pfcrt and pfmdr1 genes were detected using nested PCR and RFLP techniques in 84 P. falciparum isolates obtained from patients with acute uncomplicated malaria.

The Food and Drug Administration strengthened warnings FDA strengthens warnings on malaria drug

The Food and Drug Administration strengthened warnings about a pill used to both prevent and treat malaria on Monday, saying it can cause serious symptoms that include hallucinations amid a controversy that’s made it a drug of last resort for U.S. troops in the Middle East, Afghanistan and elsewhere. The drug, mefloquine hydrochloride, is sold under brand names including Lariam, Mephaquin or Mefliam. “The neurologic side effects can include dizziness, loss of balance, or ringing in the ears. The psychiatric side effects can include feeling anxious, mistrustful, depressed, or having hallucinations,” the FDA says in a statement.

“A boxed warning, the most serious kind of warning about these potential problems, has been added to the drug label. FDA has revised the patient Medication Guide dispensed with each prescription and wallet card to include this information and the possibility that the neurologic side effects may persist or become permanent.”

Doctors and travelers have known for years that antimalarial pills can have psychiatric effects. The drugs can be used to treat malaria. Or taken before and during travel to an affected area to prevent infection.

People who take the drugs complain they can cause nightmares, dizziness and anxiety. But most controversially, psychiatrist Dr. Elspeth Ritchie of the Washington, D.C. health department, a retired Army colonel, suggests the drug may have been a factor in the case of Army Sgt. Robert Bales, who was charged with murder last year for shooting 17 Afghan civilians

Ritchie helped write a paper in the Journal of the American Academy of Psychiatry and the Law last month detailing what she terms psychosis from using mefloquine. “Exposure to the drug has been associated with acts of violence and suicide,” she writes.
