AB As a part of an ongoing study about vertical transmission of HCV and the
possible interaction between HIV 1 and HCV, during the last 6 years we
have followed-up 87 child-bearing women (age 19-45 yr) and their 94
children (age 1 mos-9 yr). Sera from all mother-child pairs were
screened for HCV and HIV 1 antibodies by EIA: samples of
HCV-seropositive mothers and of their children were submitted for HCV
genomic analysis by PCR. We detected specific HCV antibodies in 48/87
women (55%); 41/48 of them (85%) were also HIV 1 infected. Out of the 41
HIV 1/HCV coinfected women, 38 (93%) had been IVDU and 4 (7%) were
etherosexually infected. PCR for HCV-RNA, performed in 18 of them, was
positive, evidencing multiple HCV infection in 4/18 (22%) cases (IVDU).
Type I HCV was detected in 10/18 women (55%), type II in 4/18 (22%),
type III in 2/18 (11%), type V in 7/18 (39%) and type IV in none case.
7/47 (15%) HCV-seropositive women were HIV 1 negative: 4 (57%) had been
IVDU, 2 (28%) had a history of parenteral exposure and 1 (14%) was
etherosexually infected. PCR, performed in 5/7 cases, was positive, with
evidence of multiple infection only in one case (IVDU). Type I HCV was
detected in 3/5 women (60%), type III in 2/5 (40%), type V in 2/5 (40%),
type II and IV in none case. 9/52 (17%) children born to
HCV-seropositive women were HCV infected. All the HCV infected children
had HIV 1 seropositive mothers but none of them resulted HIV 1
coinfected. Only in 1/9 cases (11%) HCV-PCR was discordant with
serologic test. Up today we found a single case of HCV vertical
transmission in which the HCV variant of the child doesn't match that of
the mother.
