Serum calcium and magnesium in leprosy.

Serum calcium and magnesium were studied in 70 leprosy patients and 25 normal healthy individuals. An attempt has been made in this study to find out if there is any correlation between the clinical and pathological status of the disease and serum calcium and magnesium levels in the blood. Serum calcium was found to be significantly decreased in lepromatous leprosy (Ca=8.42+/-0.7 mg%, P less than 0.001) and dimorphous leprosy (Ca=8.68+/-0.94 mg%, P less than 0.05) while it was normal in tuberculoid leprosy (Ca=9.14+/-2.12, P less than 0.05). The decrease in serum magnesium level was highly significant in all clinical types of leprosy (Mg=1.08+/-0.29, P less than 0.001).
