Cardiac complications of halofantrine: a prospective study of 20 patients.

Halofantrine, increasingly used for treatment of Plasmodium falciparum malaria, is a normally well-tolerated amino-alcohol with very few side-effects, but torsades de pointes ventricular tachycardia due to halofantrine has been reported in a few patients with a congenital long QT interval (Romano-Ward syndrome). We performed a prospective study of the cardiac effect of halofantrine in 20 patients with 48 h ambulatory electrocardiographic (ECG) monitoring; the halofantrine levels in their serum were also determined. Minimal ECG changes were noted, with lengthening of the QT interval without clinical symptoms. This effect was dose-dependent and can be very severe in cases of pre-existing cardiopathy; it also occurs in patients without any pre-existing cardiopathy. In order to reduce the likelihood of such incidents, which are admittedly rare, we suggest performing electrocardiography on all patients before initiating treatment with halofantrine.

Giant cell arteritis involving the lower limbs.

Giant cell arteritis is an inflammatory disease that can affect the arteries anywhere in the body. Two cases are reported in which the arteries of the lower limbs were involved. Intermittent claudication with a walking distance of only 30 m was the inaugural manifestation in both cases. A biopsy of the superficial femoral artery provided the diagnosis in the first case. Ergotamine toxicity was considered initially in the second case. Acute ischemia and gangrene requiring amputation can complicate giant cell arteritis of the lower limbs and consequently corticosteroid therapy in an effective dose should be given as soon as the diagnosis is made. The inflammatory arterial lesions improve under therapy, but irreversible fibrosis with stenosis can develop if treatment is initiated late.
