The determination of fibronectin (FN) concentration in plasma has been performed in the group of 77 patients (60-with various chronic liver diseases, 6-with AIDS IVc, 11-healthy patients). The purpose of this study was: evaluation of the value of plasma FN determination in assessment the degree of liver fibrosis and the degree of liver damage. The obtained results were compared with routine biochemical tests and histopathological picture of liver sections. Among patients with liver diseases, we observed that plasma FN concentration was significantly lower only in the group with decompensated liver cirrhosis, in relation to control group. Non significant lower values of FN was observed in the group of patients with chronic hepatitis, as well as non significant higher ones in the group with cholestasis and fibrosis. It has been concluded that determination of plasma FN concentration has not any importance in evaluation of degree of liver fibrosis and its only one from many functional liver tests.

Hepatitis C virus (HCV) is a major cause of transfusion-induced chronic liver disease in hemophiliacs, with 70% to 90% being anti-HCV positive. Seroreversion or loss of antibody response to HCV has been observed in a small proportion of human immunodeficiency virus-positive [HIV(+)] anti-HCV(+) hemophilic men. Despite the seroreversion to an anti-HCV-negative state, such patients continue to show serum alanine aminotransferase (ALT) elevations and biopsy evidence of cirrhosis and/or chronic active hepatitis. To determine the cause for the loss of anti-HCV antibody, we compared first- and second-generation anti-HCV enzyme immunosorbent assay (EIA 1.0 and 2.0), second-generation recombinant immunoblot (RIBA 2.0), and HCV-RNA amplification using polymerase chain reaction (PCR) in 19 "seroreverters" before and after seroreversion. There was no difference between 19 seroreverters and 59 persistently anti-HCV-positive hemophiliacs in mean ALT (1.1 +/- 0.1 XUL v 2.0 +/- 0.2 XUL; chi 2 = 1.80, P > .05), in mean CD4 (188 +/- 36/microL v 232 +/- 28/microL; t = 0.965, P > .05), or in the rate of progression to acquired immunodeficiency syndrome (13 of 19 [68.4%] v 30 of 59 [50.9%]; chi 2 = .987, P > .05, respectively). Before seroreversion, all 19 seroreverters (100%) were positive for EIA 1.0 and 2.0 and PCR, and all but 2 of 19 (89.5%) were RIBA 2.0 positive, whereas, after seroreversion, none were positive for EIA 1.0, 15 of 19 (78.9%) were positive for EIA 2.0, 8 of 18 (44.4%) were positive for RIBA 2.0, and 18 of 19 (94.7%) were positive for PCR. There was a lower CD4 lymphocyte number after seroreversion in those who were RIBA 2.0 negative as compared with those who were RIBA 2.0 positive (32 +/- 10/microL v 171 +/- 52/microL; t = 2.638, P > .05). These results indicate that HIV(+) anti-HCV(+) hemophilic men who undergo "HCV seroreversion" are truly infectious and anti-HCV positive by second-generation tests. Anti-HCV detection in immunosuppressed hosts is significantly improved by second-generation EIA and RIBA assays.

The inner city population of the Los Angeles county has rapidly become largely Latino. The 3.3 million Latinos living in the county in 1990 had much higher poverty rates and lower educational attainment rates than Anglo (non-Hispanic white) or blacks. The health indicators of the three groups are compared for 1990. In birth outcome, although Latinos were the least likely to receive care in the first trimester, Latinos and Anglos had identical rates of low birth weight babies, and lower rates than blacks. Latino infant mortality was the lowest of the three. The age-adjusted death rates showed that Latinos have a lower overall death rate than Anglos or blacks, and lower specific rates for heart disease, cancer, AIDS and stroke. Latinos did have higher death rates than Anglos for accidents, homicides, cirrhosis and diabetes. Latinos had incidence rates of gonorrhoea and syphilis similar to Anglos and lower than blacks. The communicable disease rates for Latinos was many times higher than Anglos or blacks, including those for measles, shigellosis, giardiasis and hepatitis A. Implications for family medicine are discussed.

The study included 11 patients with AIDS who underwent gastric emptying studies for solid food, endoscopy (esophagogastroduodenoscopy), and gastric biopsy whenever gastritis was diagnosed on endoscopy. All studies were performed within 1 week. The studies were retrospectively reviewed to analyze the changes in gastric emptying secondary to Kaposi's sarcoma (KS) with or without opportunistic infections. Two patients with KS only had rapid gastric emptying (T1/2 6.7 and 45 minutes). Two other patients with KS and opportunistic infections had normal gastric emptying (T1/2 56.7 and 70 minutes), and one patient with KS and opportunistic infections had rapid gastric emptying (T1/2 25.9 minutes). Four patients with gastritis secondary to opportunistic infections and no KS had delayed gastric emptying (T1/2 622, 92, 266.5, and 179.4 minutes). The remaining two patients had endoscopy showing gastritis not proven by biopsy, and both had rapid gastric emptying. One patient had gastric ulcer (T1/2 39 minutes), and the other had chronic active hepatitis and early cirrhosis (T1/2 15 minutes). Esophagitis was present in 6 out of 7 patients who had gastritis. Esophageal candidiasis was confirmed in three patients, and cytomegalovirus was confirmed in one patient. The findings suggest that gastroduodenal KS is associated with fast gastric emptying in patients with AIDS. However, normal gastric emptying study does not reflect normal gastric physiology in patients with AIDS.

We have studied morbidity and mortality related to hepatitis C virus infection in haemophilic patients treated at our centre. 11/255 HCV seropositive patients have developed hepatic decompensation. 20 years after first exposure to lyophilized clotting factor concentrate the risk of hepatic decompensation is estimated to be 10.8% (95% CI 3.8-17.8%). There is a significantly increased risk associated with HIV infection, and also with increased age. For HIV seropositive patients the rates of decline in CD4 lymphocyte count and the development of p24 antigenaemia are significant risk factors for hepatic decompensation. Cirrhosis was seen in 9/19 HIV seropositive patients at post mortem. There was an association of cirrhosis with increased age but not with CD4 count, p24 antigenaemia, or AIDS. In conclusion, HCV infection is associated with serious liver disease in haemophilic patients, but so far this has been restricted to a minority of those at risk. HIV co-infection accelerates progression to hepatic decompensation, and we speculate that this is probably due to enhanced HCV replication in the presence of immune deficiency.

We report the case of a patient suffering from acquired immunodeficiency syndrome and hepatitis B and D virus-related cirrhosis of the liver who was diagnosed as subclinical Crohn's disease. We attribute this clinical course to abnormality of intestinal immune system induced by the human immunodeficiency virus. Concomitant hepatitis B and D virus infection may have contributed. This observation supports the hypothesis of helper-inducer T cells (CD4 T cells) having a critical role in the immunopathogenesis of Crohn's disease and its clinical expression.

The case notes of patients with blood cultures positive for enterobacteriaceae were examined retrospectively over a 6-month period in Parirenyatwa Hospital, Harare, Zimbabwe. Speciation was possible for Salmonella typhi and shigellae only. Nontyphoidal salmonellae were serotyped. Salmonella or shigella bacteremia was identified in 51 patients. There were 14 isolates of S. typhi, 32 isolates of nontyphoidal salmonellae, and 5 isolates of shigellae species. The case notes of 38 patients could be identified for review, and of these HIV serology was available for 15 seropositive and 15 seronegative patients. The male to female ratio was approximately 3:1 for both groups and the mean age was 29.7 +or- 21. Nontyphoidal bacteremias as compared with typhoid fever were strongly associated with HIV seropositivity [p 0.01]. 3 out of 8 HIV-negative patients with nontyphoidal bacteremia had another underlying immunosuppressive disease [2 had myeloma and 1 patient had cirrhosis with complicating hepatoma]. 2 patients with nontyphoidal bacteremia whose HIV status was unknown also had another immunosuppressing disease [acute myeloid leukemia and idiopathic pancytopenia]. 13 out of 15 HIV-positive patients showed other signs of HIV infection [oral candida, herpes zoster, persistent generalized lymphadenopathy]. 3 out of 11 patients [27%] with typhoid died, while 11 out of 27 patients [40.7%] with nontyphi bacteremia died. Most strains of S. typhimurium were included in serogroup B, which accounted for 37% of nontyphoidal isolates. Earlier studies identified invasive salmonellosis in patients with other AIDS defining diseases. In Nairobi clinical features of HIV infection were found in 64% of bacteremic HIV-positive patients, but only 28% of patients fulfilled the CDC clinical case definition for AIDS. A more recent study from Nairobi demonstrated that S. typhimurium bacteremia is a common cause of intercurrent infection in HIV-positive tuberculous patients.

Pleural effusion (PE) has been increasingly diagnosed over the last eight years in the Department of Internal Medicine of the Centre Hospitalier of Kigali, Rwanda. To determine the etiology of PE and to examine its possible association with HIV-1 infection and tuberculosis (TB), the authors performed an etiological work-up, including thoracocentesis and pleural punch biopsy, of all new patients with PE of undetermined etiology referred to the Division of Pulmonary Diseases at the hospital between September 14, 1988, and October 16, 1989. 81 men and 46 women of mean age 34 years were enrolled in the study. Pleural TB was diagnosed in 86% and confirmed histologically and/or bacteriologically in 82%. 82 of the 98 pleural TB patients tested for antibody to HIV-1 were HIV-1-seropositive. Metastatic cancer was responsible for PE in six patients, Kaposi's sarcoma in three, lymphoma in one, anaplastic carcinoma in one, and adenocarcinoma in one. Non-TB pneumonia was documented in five patients and was associated with HIV-1 infection in four. Other causes of PE were congestive heart failure, decompensated cirrhosis, constrictive pericarditis, or undetermined; only one of these latter patients was HIV-seropositive. The authors therefore found TB to be the predominant cause of PE and it is strongly associated with HIV-1 infection. In an African area highly endemic for HIV-1 and Mycobacterium tuberculosis co-infection, PE should therefore be considered a good marker of TB as well as HIV-1 infection.

Primary sclerosing cholangitis (PSC) is an inflammatory disease of unknown etiology. It affects the biliary system and is characterized by fibrosis and progressive obliteration of extrahepatic and intrahepatic bile ducts. Its frequent coexistence with antibody-mediated diseases, certain human leukocyte antigens, and altered lymphocyte mechanisms suggests a strong autoimmune and genetic etiology. Other conditions such as recurrent cholangitis, acquired immunodeficiency syndrome, previous bile duct surgery, bile duct anomalies, or biliary stone disease may result in similar clinical patterns and radiologic profiles. PSC can be asymptomatic and slowly progressive over years, or it may develop rapidly with an inexorable progression to cirrhosis and portal hypertension. Clinical and biochemical abnormalities may suggest PSC, but it is the characteristic radiological pattern that secures the diagnosis. Once viewed as a rare entity, the widespread use of radiological and endoscopic methods have increased physician awareness. There is no successful medical treatment for PSC. While traditional surgical approaches have been directed at the relief of cholangitis and biliary obstruction, liver transplantation has emerged as definitive therapy for patients with PSC complicated by cirrhosis or recurrent bouts of cholangitis.

From November 1993 to December 1994, the seroprevalence of anti-HCV, HBsAg was studied among 346 HIV-infected persons (asymptomatic HIV-infected persons and AIDS patients) and 1,023 subjects from the general population (including 119 cord blood samples). The prevalence of anti-HCV, HBsAg among HIV-infected patients aged 15-45+ years was 11.0 and 11.6 per cent respectively which is significantly higher than the comparable levels for the general population (1.9% and 4.7%) in the age group 15-44 years. There was no statistically significant association of anti-HCV and HBsAg prevalence among 200 asymptomatic HIV-infected carriers and 146 AIDS patients. Assays for anti-HCV among blood donors are highly recommended to reduce the development of liver disease or cirrhosis in the immediate future.
