 AB    OBJECTIVE: The study was undertaken to detect HIV-specific DNA in plasma
       of infected individuals and compare it with the other nucleic acid
       markers of the virus i.e. HIV-specific DNA in PBL as the provirus and
       HIV-specific RNA, in the plasma of infected persons. METHODS: Blood
       samples were collected from asymptomatic, seropositive persons with risk
       behaviour of HIV-transmission, patients of AIDS and voluntary donors
       with no risk behaviour as control. All samples were first screened
       serologically and then subjected to PCR using HIV-specific primers from
       pol region. RESULTS: The study shows presence of HIV-specific DNA in the
       plasma of asymptomatic, seropositive persons as well as in plasma of
       AIDS patients. At the same time point, the PCR signals with DNA
       extracted from PBL (representing integrated proviral DNA) were either
       weak or negative. The PCR signals obtained when RNA was extracted from
       plasma of the same individuals and subjected to RT-PCR were more
       consistent than those of PBL-DNA-PCR. DNA extracted from plasma of AIDS
       patients gave positive signals with 32p labeled full length cloned
       HIV-DNA. DISCUSSION & CONCLUSION: The above results suggest that HIV
       probably also replicates through an alternative pathway of unintegrated
       DNA (J. Nandi & K. Banerjee, Med. Hyp. 40: 1-7, 1993). The plasma
       HIV-DNA can be used in early diagnosis and monitoring therapy in HIV
       infection.
