title: Effects of recombinant leukocyte interferon on serum immunoglobulin concentrations and lymphocyte subpopulations in chronic hepatitis B.
abstract: To investigate immune effects of interferon (IFN) therapy in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B, serum immunoglobulin concentrations and peripheral lymphocyte subpopulations were sequentially studied before, during, and after therapy in nine patients who were treated with recombinant human alpha-IFN in doses ranging from 3 to 10 million units per day for 28 days. Serum immunoglobulin A levels decreased significantly, from 414 +/- 23 mg/dl (mean +/- SE) to 379 +/- 28 mg/dl (P less than 0.05), after the first week of therapy and to a bottom value of 323 +/- 20 mg/dl (P less than 0.001) at the fourth week. Immunoglobulin G levels decreased significantly, from 2603 +/- 175 to 2328 +/- 169 mg/dl (P less than 0.005), after the first week of therapy and to a bottom value of 2005 +/- 199 mg/dl (P less than 0.001) at the fourth week. Immunoglobulin M levels were also reduced significantly after 3 weeks of therapy (from 229 +/- 23 to 188 +/- 15 mg/dl; P less than 0.01). These reductions in immunoglobulins A, G, and M returned to pretreatment levels by 4 months after the end of the therapy.(ABSTRACT TRUNCATED AT 250 WORDS)
