In an attempt to evaluate the prevalence, kinetics and impact of HCV infection in renal transplantation, we analyzed 140 kidney recipients according to the histopathological status of the liver. Thirty-three HBsAg-negative patients had chronic active hepatitis, 73 HBsAg-negative patients had a normal liver, 21 HBsAg-negative kidney recipients had minimal pathological changes and 13 patients had HBsAg-positive cirrhosis. Serum antibodies to HCV were detected using the ELISA from Ortho Diagnostic and confirmatory tests using the Ortho recombinant-based immunoblot assays. The overall prevalence of antiHCV antibodies was 23.6%. AntiHCV were more frequently present in HBsAg-negative patients with chronic active hepatitis (60.6%) than in HBsAg-negative patients with normal livers (8.2%) (p less than 0.0001) or minimal liver changes (33.3%) (NS) or in HBsAg-positive patients with cirrhosis (0%) (p less than 0.001). The recombinant-based immunoblot assays confirmed antiHCV-positive ELISA results in 86.7% of patients. Among the 27 antiHCV-positive kidney recipients who had serial serological follow-up, 10 (37.0%) were already positive at transplantation and remained antiHCV-positive during follow-up. Eleven patients (40.8%) acquired antiHCV an average of 95 months after renal transplantation, while antiHCV disappeared an average of 111 months after transplantation in six (22.2%), who had antiHCV prior to transplantation. The kinetics of antiHCV antibodies did not differ according to liver histology. Patient and graft survival were not different in antiHCV-positive and antiHCV-negative kidney recipients irrespective of liver histology, and there was no difference in survival between antiHCV-positive and antiHCV-negative patients with chronic hepatitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Anti-c100-3 (Ortho) was determined in the sera of 152 patients with HBs antigen-positive chronic liver diseases to assess coinfection of hepatitis B virus (HBV) and hepatitis C virus (HCV). Eleven patients (7.2%) were positive for anti-c100-3. Anti-CP-9 (Okamoto) and HCV-RNA (RT-PCR) were also examined in these 11 patients. Anti-CP-9 was detected in 7 patients and HCV-RNA was detected in all 11 patients. Four of the 11 anti-c100-3-positive patients were positive for HBe antigen (HBeAg) and others were negative. In 8 of the 11 patients, HCV was suspected to be superinfected by blood transfusion. In HBeAg-positive patients, serum glutamic pyruvic transaminase (SGPT) was elevated in relation to active replication of HBV shown by DNA-polymerase activity. The histological findings showed chronic active hepatitis, with or without cirrhosis. On the other hand, in HBeAg-negative patients, SGPT fluctuated without evidence of active replication of HBV. Active inflammation in the liver was observed in 3 of 5 HBeAg-negative patients by liver biopsy. These findings suggest that HBV might play an important role in chronic active inflammation in HBeAg-positive patients coinfected with HCV, and that HCV might be responsible for continuous inflammation in HBeAg-negative patients coinfected with HCV.

The diagnostic usefulness of anti HCV EIA test of Abbott and Ortho companies were compared. The anti HCV levels determined in the sera of 173 patients with chronic liver diseases and of 17 haemodialysed kidney patients. 109 of 190 (57%) sera were found to be negative and 81 (43%) positive determined by Abbott kit, while 127 (67%) were negative and 63 (30%) were positive by the Ortho kit. Positive results in patients with chronic liver disease were found in 66 patients by Abbott and 58 patients with Ortho Kit. Distribution of positive cases according to the diagnosis is as follows: 29 (57%) out of 51 chronic hepatitis, 17 (61%) out of 28 cirrhosis. Conflicting results were obtained in 20 cases of 190 (11%) when 17 sera were positive by Abbott and negative by ORTHO, and 3 sera were negative by Abbott, and positive by Ortho. The samples close to the cut off and with low positivity with conflicting results were checked again by the neutralization HCV EIA Abbott assay. We found the Abbott HCV EIA test more sensitive in our excellent for screening of large numbers of samples, we recommend to confirm the positive results by a neutralization type test.

An enzyme immunoassay (Ortho-HCV ELISA) for antibodies against the hepatitis C virus was used to test serum samples from 39 patients with alcoholic cirrhosis and 34 patients with alcoholic hepatitis or fatty liver. The frequency of a positive result in the cirrhotics was significantly higher than in the alcoholics without cirrhosis (38.5% vs 8.8%, P less than 0.01). However, the positive results in the cirrhotics were associated with high gammaglobulin concentrations, and optical density values in the assay correlated closely with serum globulin (r = 0.73, P less than 0.01). The findings suggest that serum from patients with alcoholic cirrhosis may contain a component that give false-positive results in the assay.

The aim of this study was to elucidate the positive rate of serum anti-HCV in alcoholic (with negative HBsAg and without blood transfusion history) and non-alcoholic (type-B and type-NANB) patients with chronic liver diseases. The clinico-pathological difference between anti-HCV positive and negative alcoholic patients was also investigated. Anti-HCV (Chiron C-100-3) was assayed with Ortho EIA kit in 196 patients. Liver function tests and the histological findings were evaluated in 111 cases of chronic hepatitis (CH) and 39 of liver cirrhosis (LC). Following results were obtained. [1] Positive rate of serum anti-HCV in alcoholic patients was 40% in CH, 36% in LC and 100% in hepatocellular carcinoma. In non-alcoholic type-NANB group, it was 75%, 68% and 69%, respectively. [2] Serum GGT/ALT ratio was higher in anti-HCV negative patients than positive patients both in CH and LC alcoholics. In non-alcoholic group, it was higher in type-NANB patients than type-B patients. [3] Among the histological findings in CH alcoholics, lymph follicles in the portal area were characteristic in anti-HCV positive patients, while these were not seen in negative patients. [4] In LC alcoholics, regenerative nodules were irregular in size in anti-HCV positive patients, while these were even and small in negative patients. [5] Serum HCV-RNA was detected in two out of 14 anti-HCV negative patients. [6] A female alcoholic patient who showed positive serum anti-HCV and negative HCV-RNA was presented. [7] For the evaluation of the influence of HCV in alcoholics, further studies have to be continued with more sensitive HCV markers.

Hepatitis C virus (HCV) has been proposed to be a cofactor in the pathogenesis of cirrhosis in patients with chronic alcoholism. The demonstration of a different liver histological pattern in anti-HCV positive patients might provide additional evidence. We studied 164 patients with chronic alcoholism, and histologically proven cirrhosis. For all of them, serum samples were collected at the time of a liver biopsy and stored at -80 degrees C. Testing for anti-HCV antibodies was done using the Ortho Diagnostic Systems Anti-HCV ELISA test. Only reproducible results were considered positive. A semi-quantitative assessment of seven histological parameters was made independently on liver biopsy samples. In the study group, 29 patients (18%) had anti-HCV antibodies. When compared with anti-HCV negative patients, both groups had similar ALT and AST seric activities. Anti-HCV positive patients had a greater score of mononuclear cells infiltrate (0.71 +/- 0.57 vs 0.41 +/- 0.52; p less than 0.05) and a lesser score of alcoholic hepatitis (0.19 +/- 0.57 vs 0.74 +/- 0.74; p less than 0.005). The scores for steatosis, perisinusoidal and perinodular fibrosis, and hepatocellular necrosis were similar in the two groups. In anti-HCV positive patients, with a clearly positive recombinant immunobinding assay (RIBA, Chiron-Ortho Diagnostic Systems), a greater score for hepatic necrosis and a lesser one for fibrosis were demonstrated. Among the seven patients with active cirrhosis, six were anti-HCV positive. Therefore, HCV is likely to play a role in the pathogenesis of liver damage in a few patients with alcoholic cirrhosis, especially, those with active cirrhosis.

A second generation recombinant immunoblot assay to detect antibodies against Hepatitis C virus (RIBA II, Ortho Diagnostic Systems) was applied to 30 serum samples repeatedly reactive to ELISA anti-HCV c100-3, 11 from hemodialysis patients, 11 from patients with chronic hepatitis and 8 from patients with cirrhosis. The assay detects individual antibodies directed to 4 antigenic components of the C virus, 2 antigens, c100 and 5-1-1 contained in the original ELISA assay and 2 new antigens, c33c and c22-3 the latter structural in nature. From the total of 30 samples, 23 (77%) were reactive, 4 (13%) indeterminate and 3 (10%) non reactive to the RIBA II assay. Much variation was observed regarding the response to each individual antigen. c22-3 was the most frequently reactive with the highest intensity. RIBA II assay confirmed a high percentage of the reactive results with the ELISA c-100-3, serum samples that were non reactive to RIBA showed a low optical density with ELISA. c22-3 was the most sensitive antigenic component.

Effective contraceptives contribute to the regulation of births, protect the health of women, reduce maternal and perinatal mortality and gynecological diseases, and prevent abortion-related complications. Complications after abortion average 30%, and among primigravidas the rate reaches 45%. Abortion can result in sterility and in the inability to carry out the pregnancy. Oral contraceptives (OCs) are used by 150 million globally. In new preparations ethinyl estradiol (EE) and levonorgestrel (LNG) are the most common components. In the 2-phase and 3-phase preparations Sequilar, Anteovin, and lipid profile safe Triquilar the gestagen component was reduced 40%. Continuin and Famulen are minipills, and Postinor is a postcoital contraceptive. Absolute contraindications of OCs include thromboembolytic diseases, severe cardiovascular system diseases, liver disorders, cirrhosis, cerebral vascular diseases, grave diabetes, jaundice, and malignant tumors of the mammae and sexual organs. Rigevidon, Triquilar, and Trisiston have high steroid content with minimal side effects. The protective effect of OCs are: 2-3 times lower risk of inflammation of the small pelvis, lower risk of malignant and benign ovarian tumors that lasts even after discontinuation, uterine cancer prevention (antiproliferation effect on the endometrium and inhibition of mitotic activity of the myometrium), and reduced risk of benign breast neoplasms. The finding that estrogen-induced risk of breast cancer increases with longterm contraceptive use in young nulliparas has not been persuasively proven. The optimal duration of uninterrupted OC use is 1-1.5 years. Monophasic estrogen-gestagen preparations include Bisecurin, Non-Ovlon, Ovidon, Rigevidon, Minisiston, and Demulen with low dosages of EE, LNG, norethisterone acetate, and diacetate ethonodiol. Norplant is a subdermal silastic capsule with effectiveness for up to 5 years.

To determine the seroprevalence of hepatitis C virus in the Philippines and compare it with the seroprevalence of hepatitis B virus infection, HBV and HCV markers in 594 serum samples collected from 392 blood donors, 123 medical and paramedical personnel, and 80 patients (45 liver diseases: 25 acute hepatitis, 9 liver cirrhosis, and 11 hepatocellular carcinoma; 28 hepatitis B carriers, and 7 chronic renal failure patients undergoing dialysis) in Davao, Mindanao Island, Philippines, were examined. HBsAg was determined by RPHA, anti-HBc by HI, anti-HBs by PHA, and HBsAg subtypes, HBeAg, and anti-HBe by EIA. HCV markers determined were anti-HCV (anti-C100-3) by ELISA (Ortho Diagnostic Systems), and anti-HCV core (anti-CP9 and/or anti-CP10) also by ELISA. Results showed that 9 (2.2%) blood donors were anti HCV positive; 69 (15.4%) were anti-HCV core positive Nine (2.2%) were HBsAg carriers; 240 (61.3%) were anti-HBs and/or anti-HBc positive (HBsAg carriers excluded from this group). Two of 123 medical and paramedical staff (1.6%) were anti-HCV positive; 11 (8.1%) were anti-HCV core positive; Eight (6.5%) were HBsAg carriers and 81 (65.8%) anti-HBs and/or anti-HBc positive. Five of 11 (45.4%) hepatocellular carcinoma patients were HBsAg carriers; 2 were anti-HCV core positive. Two of 9 liver cirrhosis patients were anti-HCV positive (1 to anti-HCV and the other to anti-HCV core).(ABSTRACT TRUNCATED AT 250 WORDS)

The seroepidemiology of HBV and HCV infections in the patients with acute and chronic liver diseases in Jakarta was investigated. The sera from 141 cases with acute hepatitis, 176 liver cirrhosis and 70 hepatocellular carcinoma (HCC) were examined. Anti-HA IgM, HBsAg, anti-HBc IgM and anti HCV (Ortho) were detected by Elisa method. In acute hepatitis, 83 cases (58.9%) out of 141 cases were hepatitis A and 9 cases (6.4%) hepatitis B. The others were diagnosed non-A, non-B (NANB) hepatitis and anti-HCV in 4 cases (11.8%) out of 34 cases with NANB hepatitis was positive. The low prevalence of anti-HCV in acute NANB hepatitis seems to be due to inadequate date of serum sampling. HBsAg and anti-HCV in liver cirrhosis were positive 36.5% and 73.9% respectively, including 22.7% of double infection. HBsAg and anti-HCV in HCC were 58.6% and 34.2%, including 17.1% of double infection. In 16.7% fo chronic liver disease (liver cirrhosis and HCC), neither HBsAg nor anti-HCV were detected.
