Sixteen of 77 patients (21 percent) with common variable immunodeficiency or IgG subclass deficiency contracted non-A, non-B hepatitis in association with intravenous infusions of immunoglobulin. The hepatitis seemed to run a more severe course in these patients than in non-immunodeficient patients. Twelve patients had clinical symptoms, and five died with hepatitis being the cause of death in two and a contributing factor in three. Liver biopsy specimens showed early chronic active hepatitis and cirrhosis. In addition to increases in liver enzymes, 13 patients had increases in alkaline phosphatase levels. All but two patients who contracted hepatitis had been given 50 mg/kg per week or more of intravenous immunoglobulin. Lymphocyte counts, T/B cell ratios, and T-lymphocyte function did not differ between those in whom hepatitis developed and those in whom it did not develop. The hepatitis was associated with more than one batch of a Swedish intravenous immunoglobulin, the immunoglobulin being derived from United States sources as well as from European plasma. Three previous brief reports in the literature have also associated non-A, non-B hepatitis with the intravenous infusion of various immunoglobulins. Biologic materials given to patients, including immunoglobulin, should, whenever possible, be prepared so as to ensure absence of viruses.

Forty eight symptomless homosexual men attending a sexually transmitted disease (STD) clinic and found by screening to have hepatitis B surface antigen (HBsAg) were followed up for a median of 10 (range six to 26) months to characterise their liver disease. Initially 33/50 (66%) of the men had increased serum liver enzyme activity and 19/47 (40%) had increased serum immunoglobulin G concentrations. Liver biopsy specimens showed acute hepatitis B in 12 (39%) and chronic hepatitis B in 19 (61%) of the 31 patients who underwent liver biopsy. The course of the infection was: acute hepatitis B in 14/48 (29%), chronic persistent hepatitis B in 23/48 (48%), chronic aggressive hepatitis B in 8/48 (17%), and cirrhosis in 3/48 (6%) of the patients. Antibodies against human immunodeficiency virus (HIV) were present in 16/45 (36%) of the patients, but the presence of antibodies to HIV did not influence the course of hepatitis B in the observation period.

Serum samples from 56 patients with biopsy-proven chronic B viral hepatitis without superimposed delta hepatitis were analyzed for the various markers of viral replication, including serum hepatitis B e Ag (HBeAg), hepatitis B virus deoxyribonucleic acid (HBV-DNA), and hepatitis B core antigen (HBcAg) in the liver tissues. Twenty-seven patients had persistent viral hepatitis (PH) and 29 patients had chronic active hepatitis (CAH) with or without cirrhosis. HBV-DNA was identified in the sera of 81% of patients with PH and 60% of patients with CAH. Significantly higher levels of HBV-DNA were found in patients with PH than in those with CAH. Both HBeAg in serum and HBcAg in liver correlated positively with serum HBV-DNA. Nine patients had serum HBV-DNA in the absence of HBeAg (four had anti-HBe), and seven of these nine patients had stainable HBcAg in the liver (two did not have staining). None of these patients had hepatic HBcAg in the absence of serum HBV-DNA. When these patients were stratified according to their epidemiologic background, serum HBV-DNA was present in a significantly higher number of male homosexuals than in any other groups. This was unrelated to their status of human immunodeficiency viral serology.

An autopsy case of clostridial gas gangrene occurring in a 54-year-old man with colon adenocarcinoma, liver cirrhosis, and diabetes mellitus is reported. The patient died 4 days after the onset of symptoms with episodes of vomiting and abdominal pain. Gangrene of both hips and perineum, hemolysis, renal failure, and disseminated intravascular coagulation were the dominant clinical features. Clostridium septicum was isolated from the subcutaneous tissue fluid. Adenocarcinoma of the ascending colon with ulceration found at autopsy was supposed to be an entry of the organism. Histologically, lesions of subcutaneous tissue and muscles were characterized by the absence of inflammatory infiltrates in spite of extensive necrosis. A summary of 35 cases of gas gangrene hospitalized to the Osaka University Hospital for the past 16 years indicates that clostridial gas gangrene patients with underlying diseases such as malignant neoplasm, diabetes, liver cirrhosis or immunodeficiency have a relatively poor prognosis.

We tested for infection with hepatitis C virus (HCV) in 58 patients affected by humoral immunodeficiencies: 43 common variable immunodeficiency (CVI), two hyper IgM syndrome (HIM), two IgG subclass deficiency, four ataxia-telangiectasia (AT), and seven X-linked agammaglobulinaemia (XLA). While the assessment of serum specific HCV antibodies in some of these patients was not informative because of the impairment in specific antibody production, the reverse transcriptase polymerase chain reaction (RT-PCR) assay used to detect serum HCV RNA was a useful method for diagnosing infection. We found that 38% of late onset hypogammaglobulinaemic patients (CVI, HIM or IgG subclass deficiency) had evidence of HCV infection. HCV infection was not detectable in patients with XLA or AT. The majority of our patients had persistent viraemia, and those who underwent liver biopsy showed histological findings of chronic hepatitis. Moreover, we could demonstrate in vitro that eight of 18 HCV-infected patients were actively producing anti-HCV antibodies, despite their impaired antibody production. The high rate of HCV infection in hypogammaglobulinaemic patients could be related to several nosocomial routes of transmission, including intravenous immune globulin administration. Despite the persistent viremia only two patients had cirrhosis and none had hepatocarcinoma.

In a prospective study, 102 hospital patients with liver disease were evaluated in West Cameroon, Africa. Blood donors, pregnant women and patients without liver disease served as controls. A total of 757 individuals were tested for markers of hepatitis A, B, C and D and for immunological markers (autoantibodies, procollagen III, alpha-foetoprotein, CA50 antigen, alpha-1-antitrypsin and antibodies to human immunodeficiency virus types 1 and 2). One-third of the liver disease patients had focal lesions on ultrasound examination. Histologically, 20 cases of cirrhosis, 14 cases of chronic hepatitis, 15 hepatocellular carcinomas and 17 cases of acute hepatitis were detected. All hepatic patients and virtually all controls had had a previous hepatitis A virus infection. Over 85% of adult patients and controls had at least one marker of hepatitis B virus infection. Over 30% of patients with liver disease had markers of possible hepatitis B virus replication. Antihepatitis C virus antibody was present in 18% of hepatic patients and in 6% of controls. Hepatitis C virus infection seems to play an important role in the development of chronic liver pathology; 40% of cirrhotic patients had a combined hepatitis B and C virus infection. Serum autoantibodies were frequently found and were not correlated with the presence of autoimmune liver disease.

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 aim of this study was to identify and describe possible alterations of bone histomorphometry in patients with human immunodeficiency virus (HIV-1) infection and to assess the relation between these alterations and disease severity. Forty-four HIV-1-infected patients seen successively at our hospital were evaluated for the study. In an attempt to avoid confounding factors as far as possible, we excluded patients who fulfilled any of the following criteria: age less than 18 or greater than 40 years; recent history of extended bed rest; previous diagnosis of metabolic bone disease, renal insufficiency, or hepatic failure; clinical or echographic signs of liver cirrhosis; diabetes mellitus or previous diagnosis of other endocrine diseases; drug therapy that could act on bone metabolism; and/or moderate to severe nutritional alteration. Twenty-two patients (13 men, 9 women; age: 27.9 +/- 4.1 years, mean +/- standard deviation) were included in the study. Plasma and urine biochemistry and calcium-regulating hormones were determined. Bone mineral content was measured on vertebrae L2 to L4 and on the neck and intertrochanteric areas of the femur by dual-photon absorptiometry. A transiliac bone biopsy was performed after double-tetracycline labelling, with histomorphometric study of undecalcified bone. Serum osteocalcin was found to be lower in patients who, according to the Centers for Disease Control (CDC) classification, had greater disease severity, and showed a positive correlation with the number of CD4+ T lymphocytes. No alterations in bone densitometry were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical cure of hemophilia A by orthotopic liver transplantation has been reported in 11 cases. We describe the first successful Italian case. A 27-year-old man had cirrhosis caused by previous infections with the hepatitis B, C and D viruses following life-long treatment with factor VIII concentrates made from large plasma pools. He was, however, seronegative for the human immunodeficiency virus. In the year before transplantation, life-threatening gastrointestinal bleeding due to severe esophageal varices required a large transfusion regimen (on average, 13 bags of red cell concentrates and 35,000 U of factor VIII/week). To perform orthotopic liver transplantation 8,000 U of factor VIII were given during surgery together with 10 bags of red cells and 11 of fresh-frozen plasma. Intraoperative bleeding was not different from that of non-hemophilic patients undergoing orthotopic liver transplantation. No additional factor VIII was used after transplantation and factor VIII levels in plasma were always above 50 U/dl, reaching the highest value of 184 U/dl on day 4 post transplantation. He was discharged from hospital 10 weeks after transplantation with factor VIII levels of 68 U/dl. All virological markers are currently negative, except anti-hepatitis C virus antibodies. In this patient orthotopic liver transplantation was a life-saving treatment for end-stage cirrhosis and a cure for hemophilia A.

Tumour necrosis factor-alpha (TNF) stimulates cytomegalovirus (CMV) activity in a transfected human monocytic cell line. We assessed whether this finding is relevant in vivo by evaluating the frequency of active CMV infection in patients with diseases that enhance plasma TNF. In septic disease, peripheral blood mononuclear cells of almost all patients studied were positive for CMV. Furthermore, CMV antigenaemia and enhanced plasma TNF occurred in many patients with liver cirrhosis, common variable immunodeficiency, and B-cell chronic lymphocytic leukaemia. Thus, TNF may have a central role in CMV reactivation.
