ANTI M. leprae IgM ANTIBODY DETERMINATION BY ULTRAMICROIMMUNOENZYMATIC (UMELISA HANSEN) FOR THE DIAGNOSIS AND MONITORING LEPROSY
The relationship between the IgM antibody response, antigenic load as well as the clinical improvement after chemotherapy was studied in order to obtain useful data for the early diagnosis and monitoring leprosy. A level of 82% (94/115) agreement was obtained between IgM UMELISA HANSEN and slitskin...

The relationship between the IgM antibody response, antigenic load as well as the clinical improvement after chemotherapy was studied in order to obtain useful data for the early diagnosis and monitoring leprosy. A level of 82% (94/115) agreement was obtained between IgM UMELISA HANSEN and slitskin smear examination. Discrepant results were observed in 16 patients who showed positive IgM response despite negative by the skin smear examination. In these patients, the IgM response was seen to be associated to the early signal for bacilli recurrence in the skin. In one of these patients the presence of bacilli was demonstrated in the skin, two months after IgM antibodies being detected by UMELISA HANSEN. Also in one of the treated patients positive by both diagnostic techniques, a remarkable decrease in the IgM antibody levels was seen, correlating with a significant clinical improvement. Moreover it was found a direct relationship between the IgM antibody response and bacterial antigenic load, regardless the time elapsed in the disease's evolution.
