The analysis of the drinking habits and the incidence of pulmonary tuberculosis has shown a relatively high percentage (47%) among patients with pulmonary tuberculosis taking alcoholic beverages compared to 15% among age and sex matched controls. The incidence of pulmonary tuberculosis is high among those drinking regularly or frequently and in moderate or heavy amount of alcohol. Often they exhibit moderately advanced or far advanced disease. Alcoholism decreases host resistance to infection from malnutrition, impaired bronchial clearance and defective neutrophil chemotaxis. It is necessary to look for pulmonary tuberculosis among regular, heavy drinkers of alcohol.
