Undernutrition in lepromatous leprosy. V. Severe nutritional deficit in lepromatous patients co-infected with pulmonary tuberculosis.
We have compared the nutritional status of patients with lepromatous leprosy coinfected with pulmonary tuberculosis (18 cases) with that of lepromatous leprosy (239 cases) and of pulmonary tuberculosis (21 cases) and with that of healthy controls. There was a severe weight loss and reduction of skinfold thickness in the patients with pulmonary tuberculosis as well as in lepromatous patients with associated pulmonary tuberculosis, but not in patients with lepromatous leprosy. Levels in sera of diet-dependent proteins, such as albumin, prealbumin and retinol binding protein, were significantly decreased in all three groups of patients; on the other hand, levels of the diet-independent proteins, such as the immunoglobulins, were raised in all the groups, particularly in the pulmonary tuberculosis patients as compared with healthy controls. Serum transferrin levels were decreased only in the tuberculosis patients with or without lepromatous leprosy, but not in patients with leprosy alone. While haemoglobin levels decreased in all patient groups, serum iron concentrations were reduced most in lepromatous patients concomitantly infected with pulmonary tuberculosis. Serum ferritin levels increased in the sera of pulmonary tuberculosis and lepromatous leprosy patients, but was severely reduced in lepromatous patients with associated pulmonary tuberculosis. Mean serum zinc and calcium levels were decreased in all three groups of patients, while the serum copper concentration was increased in all of them compared with healthy controls. Also, inorganic phosphorus was elevated in tuberculosis and lepromatous patients coinfected with pulmonary tuberculosis, but not in lepromatous patients. Serum calcitonin levels were increased in all patient groups indicating an inverse correlation between serum calcium and calcitonin levels. This is the first comparative report describing the status of macro- and micronutrients in two most important mycobacterial diseases of the third world countries.
