Twenty patients with rheumatic fever were followed for 24 weeks to evaluate changes occuring over the course of the disease. Total leukocyte and lymphocyte counts were increased in patients with rheumatic fever and to a lesser extent in those with rheumatic heart disease, when compared with controls. The difference between the two groups was significant. Patients with acute rheumatic fever had an increased number of B cells and a smaller increase in total T and T\u2010helper\u2010inducer (CD\u20104) cells. The proportion of B cells increased, while that of T\u2010suppressor\u2010cytotoxic (CD\u20108) cells fell. An increased number and proportion of B cells was also seen in patients with rheumatic heart disease. Total T and T\u2010helper lymphocyte percentages and numbers were significantly higher in patients with rheumatic fever compared with those of patients with rheumatic heart disease. Follow\u2010up studies at 6, 12, and 24 weeks revealed no significant differences from the entry point studies, although there was a trend toward reduction in the degree of derangement from normal values. Patients with uncomplicated streptococcal pharyngitis, however, did not show perturbations in the T\u2010cell and T\u2010subset counts. Our study suggests that the immunoregulatory defect in acute rheumatic fever is characterized by a relative reduction of suppressor T cells with an absolute increase in helper T cells and B cells, resulting in an increased cellular as well as humoral immune response. The persistent alteration in B cells in the patients with chronic rheumatic heart disease suggests an ongoing immunoinflammatory process during the apparently quiescent phase.<\/jats:p>","DOI":"10.1002\/clc.4960120106","type":"journal-article","created":{"date-parts":[[2009,8,8]],"date-time":"2009-08-08T09:23:02Z","timestamp":1249723382000},"page":"34-38","source":"Crossref","is-referenced-by-count":25,"title":["Lymphocyte subsets in acute rheumatic fever and rheumatic heart disease"],"prefix":"10.1002","volume":"12","author":[{"given":"R.","family":"Bhatia","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Narula","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.
