title: Changes in hematologic parameters among Japanese HTLV-I carriers.
abstract: Hematologic data from 1,039 persons who participated in the Miyazaki Cohort study on human T-cell lymphotropic virus type-I (HTLV-I) infection were analyzed. Individuals were classified by HTLV-I antibody status and the presence of abnormal lymphocytes (Ably). We identified several differences in selected leukocyte populations: lymphocyte percent was higher among the HTLV-I carriers with Ably (36.5 +/- 2.0%, n = 29) compared with the carriers without Ably (33.1 +/- 0.6%, n = 299) and the seronegatives 36.4 +/- 0.4%, n = 711) (p = 0.04). Conversely, there was a trend of decreasing eosinophil percent among both carrier groups with the lowest percent among carriers with Ably (1.8 +/- 0.5%) compared with the seronegatives (2.8 +/- 0.1%) (p = 0.05). Mean basophil percent was decreased among both carriers groups (p = 0.09). Additionally, red cell count was elevated among the carriers with Ably (461 +/- 7 x 10(4)/mm3) compared with the seronegatives (446 +/- 2 x 10(4)/mm3) (p = 0.03). The HTLV-I carriers with Ably had lower serum albumin (4.39 +/- 0.05 g%) compared with the seronegatives (4.47 +/- 0.01 g%) (p = 0.10). These alterations may be a consequence of HTLV-I infection, with the greatest changes among carriers with Ably, a subset thought to be at risk for developing adult T-cell leukemia.
