Clinical and laboratory studies in patients with leprosy and enthesitis.

In a combined clinical, radiological, and laboratory study of 77 patients throughout the leprosy spectrum, 10 patients had an enthesitis which has not been described previously as far as is known and which was not associated with the characteristics of erythema nodosum leprosum reactions. C reactive protein and alpha 1 acid glycoprotein values were significantly lowered only in those patients with leprosy and enthesitis. No radiological abnormalities were found.
