The prevention of mother-to-child HIV transmission programme and infant feeding practices.

Since the first cases of HIV transmission through breast-feeding were documented, a fierce debate has raged on appropriate guidelines for infant feeding in resource-poor settings. A major problem is determining when it is safe and feasible to formula-feed, as breast-milk protects against other diseases. A cross-sectional survey of 113 women attending the programme for the prevention of mother-to-child transmission in Khayelitsha, Cape Town, was conducted. Over 95% of women on the programme formula-fed their infants and did not breast-feed at all. Seventy per cent of women said that their infant had never had diarrhoea, and only 3% of children had had two episodes of diarrhoea. Focus groups identified the main reasons for not breast-feeding given by women to their families and those around them. Formula feeding is safe and feasible in an urban environment where sufficient potable water is available.

A randomised, double-blind, placebo-controlled clinical trial of vitamin A in severe malaria in hospitalised Mozambican children.

This paper reports a randomised, double-blind, placebo-controlled clinical trial of the effect of routine vitamin A supplementation given on admission to children with severe malaria with regard to survival, recovery during hospitalisation and outcome 6 weeks after discharge. Children aged between 6 and 72 months admitted to the paediatric wards of the Central Hospital of Maputo (CHM), Mozambique with a diagnosis of severe malaria were randomly assigned either to a control group (placebo) or an experimental group (vitamin A) and were followed up 6 weeks after discharge. There were 280 children in the experimental and 290 in the placebo group. Seven (2.5%) and 13 (4.5%) children died in the experimental and the placebo groups, respectively, a relative risk of death of 0.56 (95% CI 0.23-1.38, p = 0.201). During the 1st 5 hours of admission, the relative risk of death in the vitamin A-supplemented group was 2.54 (0.50-12.96); after 5 hours of admission it was 0.19 (95% CI 0.04-0.85; p = 0.015). In the supplemented group, 4/82 (4.9%) of the children developed neurological sequelae vs 2/78 (2.6%) in the placebo group (RR = 1.90; 95% CI 0.36-10.09; p = 0.682). Although the overall reduction in the risk of death observed for all children receiving vitamin A is not statistically significant, it might be clinically important. This finding cannot, however, be accepted as a firm conclusion and requires validation by future trials.

Treatment for iron deficiency anaemia with a combined supplementation of iron, vitamin A and zinc in women of Dinajpur, Bangladesh.

OBJECTIVE: The study was set up to determine to what extent the addition of a supplement of vitamin A alone or in combination with zinc would improve standard iron treatment and correction of iron deficiency anaemia. DESIGN: 216 non-pregnant anaemic women of 15-45 years of age with haemoglobin levels < or = 100 g/l were randomly assigned to three treatment groups. One group (A) received iron alone, a second group (B) received iron and vitamin A, and a third group (C) received iron, vitamin A and zinc. Every woman was given one iron capsule per day for 60 days as FeSO4 containing 60 mg of elemental iron. In addition, groups B and C received 200,000 i.u. of vitamin A, given as a supervised dose, on the first day of the treatment after collection of the blood sample. Group C received one zinc tablet per day for 60 days as zinc gluconate containing 15 mg of elemental zinc. SETTING: The north-western part of Bangladesh in the urban slums of Dinajpur district between February and August 1995. SUBJECTS: To select women with a haemoglobin level of < or = 100 g/l, all the women of four randomly selected municipal slums of the district in the targeted age group (328) were invited to take part in the study. Blood samples were analysed for haemoglobin, serum iron, total iron binding capacity (TIBC), ferritin, retinol and zinc. RESULTS: Out of the 328 women screened, 254 (77.5%) had a haemoglobin level < or = 100 g/l and 322 (98%) < or = 120 g/l. The three treatment schedules significantly increased haemoglobin levels and improved iron parameters, except for serum iron in the group who received iron alone. The group who received iron, vitamin A and zinc responded best with an increase in haemoglobin of 17.9 g/l as compared to the group receiving iron alone (13.4 g/l). Iron and vitamin A treatment gave an intermediate response of 15.9 g/l. However, these differences are only statistically significant only for the group who received iron, vitamin A and zinc and only for the increase in haemoglobin, P = 0.03. CONCLUSION: The results are suggestive that the addition of vitamin A and zinc to the treatment for anaemia can increase haemoglobin levels more than with iron alone.

A nutritional profile of non-pregnant women from the slums of Dinajpur, Bangladesh.

The health and nutritional status of many urban slum dwellers in the developing world is said to be deteriorating. The nutritional profile of 328 adult, non-pregnant women from the slums of Dinajpur, Bangladesh, confirms this. Results of a cross-sectional survey showed that approximately half the women were acutely malnourished and all but six were anaemic. This, despite the fact that the slums of Dinajpur are considered relatively 'better-off' than many in the developing world; most families having permanent land tenureship, and access to basic education and health services.

Identifying malaria control issues: a district hospital-based evaluation.

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.
