title: [The prevalence of serum IgG antibodies against HTLV viruses type I and II in sarcoidosis patients].
abstract: The pathogenesis of sarcoidosis remains still unknown. Among numerous factors viruses are considered as potential causes. The aim of the study was investigation of human T-cell lymphotopic virus type I (HTLV-I) in sarcoidosis patients. Studied group (I) consisted of 52 patients: 29 women and 23 men aged from 24 to 62 years; mean age 40 years. The diagnosis of sarcoidosis was confirmed by histologic examination in 46 patients and on the base of clinical, HRCT--chest scan and BAL findings in 6 patients. Control group (II) consisted of 92 various pulmonary disorders patients and healthy subjects in the aged from 20 to 83 years; mean age 54 years. In both groups the ELISA test detecting antibodies against HTLV-I/II was performed with the use the diagnostic kit produced by Organon Teknika, Belgium. Results were interpreted by measuring the optical density (OD). The cut-off point 0.386 was established according to the rule defined by kit's producent. The values of OD ranged in group I from 0.061 to 0.384 and in group II from 0.047 to 0.213; thus, no positive results of the test were observed. The values of OD did not differ significantly in both groups (p = 0.59).
  
  
  CONCLUSIONS
  In our region the participation of HTLV-I in the pathogenesis of sarcoidosis is doubtful.
