Hypertension in the West Indies.

Hypertension is the most common chronic disease in the West Indies, and is a major health problem today being among the 10 most common causes of death in the English-speaking territories of the region. Most patients have essential hypertension. Renal failure, stroke, and cardiac failure are the most common complications, myocardial infarction being relatively uncommon in black patients. While an earlier report from the Caribbean suggested that beta-blockers were not effective for treating black hypertensives, recent experience with these drugs show that they are useful particularly when administered along with a diuretic. Beta-blockers may be required in higher doses than those commonly recommended for patients in Europe and North America, but even small doses of thiazide diuretics are effective in lowering the blood pressure of West Indian hypertensives. West Indians show a combination of personalistic, naturalistic, and modern medical beliefs, which need to be understood in order to mount effective programmes for the management of hypertension in the community.

A survey of parasites in primary school children in Dominica, West Indies.

A study of Dominican school children aged four to twelve years showed that infection with gastrointestinal parasites was very common. Trichuris was found in the stools in 92% of the children, Ascaris in 38%, Necator in 11%, Giardia in 18% and E. histolytica in 1%. In spite of the high prevalence of parasites, the general health of the children studied was remarkably good, and only 18 of the 1000 children were found to have a haemoglobin level below 10 g/dl.

Prevalence of drug-induced immunologic changes in hypertensive Jamaicans.

Of 137 hypertensive black Jamaicans who took methyldopa for a mean period of 36 months, a positive ANA was found in 1.5% and a positive direct Coombs' test in 0.7%. In 36 patients in whom hydralazine was included in the therapeutic regimen, a positive ANA was seen in only 6%. These results suggest that in black populations, immunologic abnormalities induced by antihypertensive drugs are less common than has been reported in white patients.
