Malaria prevention reduces in-hospital mortality among severely ill tuberculosis patients: a three-step intervention in Bissau, Guinea-Bissau.

BACKGROUND: Malaria and Tuberculosis (TB) are important causes of morbidity and mortality in Africa. Malaria prevention reduces mortality among HIV patients, pregnant women and children, but its role in TB patients is not clear. In the TB National Reference Center in Guinea-Bissau, admitted patients are in severe clinical conditions and mortality during the rainy season is high. We performed a three-step malaria prevention program to reduce mortality in TB patients during the rainy season. METHODS: Since 2005 Permethrin treated bed nets were given to every patient. Since 2006 environmental prevention with permethrin derivates was performed both indoor and outdoor during the rainy season. In 2007 cotrimoxazole prophylaxis was added during the rainy season. Care was without charge; health education on malaria prevention was performed weekly. Primary outcomes were death, discharge, drop-out. RESULTS: 427, 346, 549 patients were admitted in 2005, 2006, 2007, respectively. Mortality dropped from 26.46% in 2005 to 18.76% in 2007 (p-value 0.003), due to the significant reduction in rainy season mortality (death/discharge ratio: 0.79, 0.55 and 0.26 in 2005, 2006 and 2007 respectively; p-value 0.001) while dry season mortality remained constant (0.39, 0.37 and 0.32; p-value 0.647). Costs of malaria prevention were limited: 2€/person. No drop-outs were observed. Health education attendance was 96-99%. CONCLUSIONS: Malaria prevention in African tertiary care hospitals seems feasible with limited costs. Vector control, personal protection and cotrimoxazole prophylaxis seem to reduce mortality in severely ill TB patients. Prospective randomized trials are needed to confirm our findings in similar settings.

A short-term intervention for the treatment of severe malnutrition in a post-conflict country: results of a survey in Guinea Bissau.

OBJECTIVES: To determine (i) the extent of malnutrition and the risk factors for severe malnutrition in Guinea Bissau, a post-conflict country experiencing long-term consequences of civil war; and (ii) the feasibility and effectiveness of a short-term intervention characterized by outpatient treatment with locally produced food for the treatment of severe malnutrition during the rainy season. DESIGN AND SETTING: Social, clinical, nutritional information were collected for children reaching the paediatric outpatient clinic of the Hospital 'Comunità di Sant'Egidio' in Bissau, Guinea Bissau, from 1 July to 12 August 2003. Severely malnourished children (weight-for-age <-3sd) in poor health status were admitted for daily nutritional and pharmacological treatment until complete recovery. Social and health indicators were analysed to define risk factors of severe malnutrition. RESULTS: In total, 2642 children were visited (age range: 1 month-17 years). Fever, cough and dermatological problems were the main reasons for access. Social data outlined poor housing conditions: 86.4 % used water from unprotected wells, 97.3 % did not have a bathroom at home, 78.2 % lived in a mud house. Weight-for-age was <-2sd in 23.0 % of the children and <-3sd in 10.3 %; thirty-seven children (1.4 %) were severely malnourished and admitted for day care. All recovered with a weight gain of 4.45 g/kg per d, none died or relapsed after 1 year. Severely malnourished children were mainly infants, part of large families and had illiterate mothers. CONCLUSION: Short-term interventions performed in post-conflict countries during seasons of high burden of disease and malnutrition are feasible and successful at low cost; day-care treatment of severe malnutrition with locally produced food is an option that can be tested in other settings.
