Résumé
Serum haptoglobin level and its phenotypes were studied in 208 normal people and 176 malignant lymphoma patients consisting of 112 Non-Hodgkin's Lymphoma (NHL) and 64 Hodgkin's Disease (HD) at Tata Memorial Hospital, Bombay and were correlated with the clinical stages of the lymphomas. Haptoglobin (Hp) levels were also estimated in the patients at different intervals during their chemotherapy. Hp level was found significantly increased to 147.83 +/- 8.67 in NHL and 173.57 +/- 13.31 in HD as compared to 67.46 +/- 2.53 in the controls. The phenotypic and gene frequencies in the lymphoma patients did not differ significantly from those of the controls. All the clinical stages, except stage I, of NHL and HD revealed significant rise in Hp level when compared with the controls. When different clinical stages of NHL and HD were compared separately, HD showed significant rise in HP level over the NHL only in Stage IV (p less than 0.05). Significant reduction in Hp level was observed when the disease regressed due to chemotherapy but it again increased with the relapse of the disease. Thus, the study of serum haptoglobin levels at intervals in lymphoma patients would help to understand the regression or relapse of the disease and also the prognosis.
