Effect of leprosy sera and foetal calf serum (FCS) on the T cell number of peripheral blood of leprosy patients.

Study was conducted in 24 cases of various types of leprosy and 10 healthy controls to find out the effect of various sera on the T cell count of peripheral blood lymphocytes by sheep erythrocyte rosetting method. The percentage of T lymphocytes in lepromatous and tuberculoid cases were significantly lower compared to that in normal healthy controls. All sera except FCS had a stimulatory effect on the number of T cells. The cells incubated for 24 hours in FCS did not show any stimulatory effect on the number of T cells, however, these FCS incubated cells showed a significant elevation in the number of T cells when further incubated in sera either from leprosy cases or from healthy subjects.

Evaluation of standard Dharmendra lepromin.

Dharmendra lepromin standardized at Central JALMA Institute for Leprosy (CJIL) by bacterial counts was used by different observers in four different Centres to assess the early and late reactions. Patients taken into the study were from different ethnic groups in different regions of the country. Comparable skin reactions were found at the Bombay Leprosy Project (BLP), Bombay and at the CJIL, Agra wherein a large number of patients were taken in the study. Similarly, when a smaller number of patients were taken in the study at the Base Hospital (BH), Barrackpore, and at the Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry, the skin reactions noted in patients at these Centres were again found to be statistically comparable.

Dermatoglyphics in leprosy (I. Finger patterns).

Finger dermatoglyphic patterns were studied in leprosy families selecting patients and controls from each family. A total of 100 leprosy cases (50 of TT/BT types and 50 of BL/LL types) and 100 control subjects were investigated. While a statistically significant association was noted with some finger patterns (loop ulnar, loop radial, loop twin and loop central pocket) in the lepromatous type, no such association was observed with the finger patterns in the tuberculoid type.

Group specific component (Gc) in erythema nodosum leprosum (ENL).

The distribution of phenotypes of group specific component (Gc) was examined in 71 lepromatous leprosy (LL) patients without any history of ENL reaction and 65 LL patients with history of frequent episodes of ENL reaction. The distribution of none of the phenotypes of Gc (Gc 1-1, Gc 2-1, Gc 2-2) was statistically significant among these groups.
