RESUMEN
Autonomic functions were studied by six standard tests in 65 patients with lepromatous leprosy and 25 healthy controls. Dysautonomia was observed in 22 patients, all having the disease for more than five years. Associated peripheral neuropathy, judged clinically, was present in all, except one patient. Of the 22 dysautonomic patients, 9 each had mild or moderate dysantonomia and 4 had severe dysautonomia as per the scoring schedule devised by us. Syncope, gustatory sweating and impotence were the symptoms suggestive of dysautonomia. But not all affected patients reported these symptoms. Involvement of the sympathetic system was more frequent than that of the parasympathetic system. Statistically significant abnormality was seen with Atropine ratio, standing 30:15 beat ratio, postural hypotension and sustained hand grip test. Sustained hand grip test was the one which consistently gave abnormal results in all the 22 dysautonomic patients.
