ASSOCIATION OF TUBERCULOSIS WITH SEVERE ACUTE MALNUTRITION

BACKGROUND: India houses highest number of malnourished children next to African countries. Malnutrition is lethal in combination with Tuberculosis. Efficacy of BCG vaccination, a part of Universal Immunization Programme in preventing TB infection and utility of TST in detection of TB infection in malnourished children needs to be studied. OBJECTIVE: 1. To obtain the morbidity pattern of tuberculosis. 2. To study the role of BCG vaccination and reliability of TST in under five children with severe acute malnutrition. MATERIAL AND METHODS: DESIGN: A prospective study. SETTING: Severe malnutrition unit in a tertiary level referral hospital in central India. PARTICIPANTS: Under five children with severe acute malnutrition in SMTU. OUTCOME MEASURES: 1. Presence of tuberculosis in SAM children. 2. Morbidity pattern of tuberculosis in SAM children. 3. Presence of BCG scar in diseased children. 4. Reactivity status of TST in diseased children. RESULTS: Tuberculosis was diagnosed in 22% of severe acute malnutrition cases. Seventy eight percent (78.50%) of the pulmonary tuberculosis cases were younger than 1 year. In children of 13-26 months of age, 50% of cases were pulmonary tuberculosis while neuro-tuberculosis and disseminated tuberculosis contributed 25% each. BCG scar was present in 86.6% of malnourished children with pulmonary tuberculosis while only 28.4% of extra pulmonary seriously ill cases had BCG scar. Positive tuberculin reaction was seen in only 8.0% children, 50% of them had 10-15mm induration. CONCLUSION: Tuberculosis is one of the treatable causes of malnutrition and there is high prevalence of tuberculosis infection among SAM children. Identifying adult cases and giving proper treatment as well as screening their malnourished children will help in early identification and preventing spread of pulmonary TB among children.
