Although the major diseases transmitted by transfusion today are AIDS and hepatitis, many others also are known. These include CMV, syphilis, Chagas disease, babesiosis, parvovirus B19, malaria, Epstein-Barr infection, and many others that have been reported only once or twice. Reducing the risk of transfusion-transmitted diseases is a problem for donor centers where donor screening and laboratory testing for possible carriers is undertaken. Physicians should be aware that the potential for disease transmission is always present when transfusions are administered.

The aim of the study was to examine the frequency, severity, persistence and etiology of relapses occurring during the hepatitis A viral infection. Therefore, a prospective study of 910 patients suffering from hepatitis A (HA) was carried out. The clinical examination and determination of glutamyl pyruvic transaminase (GPT) in the serum every 7-14 days till recovery (usually during 6--8 months) were performed. HAV infection was confirmed by detecting anti-HAV IgM in the blood of all the examined by radioimmunoassay. In 876 (93.3%) patients HA had typical clinical features and a monophasic course. All cases made a rapid clinical recovery and liver function tests improved strikingly between 1 and 4 months after the onset of illness. However, in 34 (3.7%) of 910 patients, after an asymptomatic interval of 4--8 weeks, relapsing hepatitis occurred. Mild clinical symptoms: fatigue, myalgia, nausea, epigastric discomfort accompanied by the elevated levels of GPT in the serum were noticed in 11 patients, while 3 of them redeveloped jaundice. In 23 remaining patients relapses of hepatitis were asymptomatic, except for the reappearance of icterus in six cases. The only way to establish the exacerbation of the disease was through the pathological findings of GPT in the serum, which increased 10--60 times above the upper limit of the normal value. While 25 patients had one relapse, in 9 there were two or more relapses, so that hepatitis had a biphasic or polyphasic course. The second relapse was registered 3--6 weeks after the first one disappeared. Through biochemical tests the average values of the GPT were established: 1566 U/L in the acute stage, 107 U/L during the early stage of convalescence and 1016 U/L during the first relapse of hepatitis. After the first relapse and during remission, in 9 patients the average values of GPT in the serum were 84 U/L, while during the second relapse 518 U/L. Clinical signs of relapsing hepatitis disappeared approximately in 4 days, but liver function tests decreased slowly and persisted elevated between 5 and 12 months. A possibility of establishing the etiology of relapsing hepatitis, which has yet remained unknown, is discussed. Anti-HAV IgM were present in all 34 patients during the initial and relapsing phase of hepatitis and in 26 cases in the latter phase of convalescence between 9 and 11 months after the beginning of the disease. Serological tests excluded infection with hepatitis B, cytomegalovirus and Epstein-Barr virus. With a great probability other infections and toxic agents damaging the liver could have been excluded.(ABSTRACT TRUNCATED AT 400 WORDS)

Hepatitis may be caused by hepatitis A virus, hepatitis B virus, hepatitis C virus (classic non-A non-B viral hepatitis), hepatitis D virus (delta agent), and hepatitis E virus (epidemic non-A non-B viral hepatitis). Cytomegalovirus, Epstein-Barr virus, and herpes simplex virus may also occasionally cause hepatitis. Some forms of hepatitis carry the risks of chronic infection, cirrhosis, or hepatocellular carcinoma. Treatment options for viral hepatitis are limited and, in many cases, still under investigation. Prophylaxis is available for many forms of hepatitis and should be offered to those at risk.

The incidence and morbidity of viral and Toxoplasma gondii infections were studied in 40 children who underwent liver transplantation between December 1983 and February 1988. The incidence of primary and reactivated cytomegalovirus (CMV) infection was 19% and 47%, respectively; primary infection caused clinical disease in all five cases affected and was fatal in one. Primary Epstein-Barr virus (EBV) infection occurred in 10 (26%) recipients but caused only mild disease. No reactivated EBV infection was recorded and no lymphoproliferative disorders associated with EBV were found after a maximum of four years' follow up. Adenovirus infection occurred in seven (18%) patients; this was associated in one case with fatal pneumonia and fulminant hepatitis, but otherwise with only mild respiratory disease. Primary T gondii infection was detected in one patient who remained asymptomatic. Other viruses causing infection included herpes simplex, varicella zoster, and respiratory syncytial virus. Surveillance for these infections and the long term sequelae should be included in the follow up of all children who undergo transplantation.

Over the past 10 years, 12,146 cases of hepatitis were diagnosed in the Virology Department of Vienna University. 30.3% were hepatitis A, 39.2% hepatitis B, 3.0% cytomegalovirus and 1.5% Epstein-Barr virus infections. The remaining 25.8% were diagnosed as non-A, non-B hepatitis (NANB). Therefrom, a sample of 167 sera from acute and 78 from chronic hepatitis NANB were tested for hepatitis C. 9.6% of the acute and 44.9% of the chronic cases were positive. We conclude from these data that about 12% of all hepatitis cases in Austria are caused by the hepatitis C virus. In addition, risk groups for hepatitis C were tested. The highest prevalence (80%) was found in drug addicts. Polytransfused (organ transplanted) patients had antibodies in 44.8% of cases. Of 78 dialysis patients, 7 were positive but nearly all positives came from one single dialysis unit, thus indicating a prevalence of 30% there.

A 50-year-old male without relevant past history was admitted because of fever lasting for 23 days. Physical examination showed hepatomegaly and splenomegaly without other findings. Laboratory studies only revealed mildly abnormal hepatic enzymes. The remaining investigations (markers, serologies, antinuclear antibodies, blood and urine cultures) were negative. Chest and abdomen X-ray films were normal. In abdominal echogram a homogeneous liver without space occupying lesions was seen, and computed tomography disclosed enlarged liver, spleen and lymph nodes. Needle hepatic biopsy was reported as showing reactive hepatitis. Although clinically meningeal antibody seroconversions were not found, DNA chains of cytomegalovirus, Epstein-Barr virus, hepatitis B virus and herpes virus simplex were investigated with the in situ hybridisation technique. Its result was a strongly positive hybridisation for herpes virus and negative for the other investigated viruses.

Bone marrow transplantation is complicated by a sequential occurrence of viral infections, the predictability of which influences disease management. Among these infections are herpes simplex virus, cytomegalovirus, varicella zoster virus, Epstein-Barr virus, respiratory viral infections, hepatitis viral infections, and gastrointestinal infections. The approach to the treatment and prevention of these infections is discussed.

Reactivated Epstein-Barr virus infection associated with hepatitis appeared in a liver transplant patient receiving monoclonal OKT-3 antibody for rejection. The histologic findings in liver biopsy specimens characteristic of allograft rejection were observed prior to and during the initial phase of antirejection therapy. However, failure of a complete response to antirejection therapy promoted rebiopsy. The specimen showed portal infiltrates composed predominantly of plasma cells and immunoblasts. The presumptive diagnosis of Epstein-Barr virus hepatitis was confirmed by staining frozen liver tissue for Epstein-Barr virus nuclear-associated antigen. OKT-3 therapy was discontinued, and cyclosporine and steroid doses were reduced. Gradually, clinical features, serum aminotransferase and bilirubin levels, and the portal lymphoid infiltrate resolved. Epstein-Barr virus serology showed an increase in convalescent titers IgG-antiviral capsid antigen, and Epstein-Barr virus nuclear-associated antigen. The histologic, clinical, and laboratory features supporting the diagnosis of Epstein-Barr virus hepatitis in a liver transplant patient are presented and discussed. This diagnosis guided appropriate therapy.

Epstein-Barr-Virus-(EBV)-infections are well known to cause acute infectious mononucleosis in adolescents and young adults. However in early infancy and childhood these infections are usually mild and clinically inapparent. In the following we describe a case of a primary EBV-infection in infancy, which led to a transient hepatitis, identified by pathologically elevated liver enzymes.

For 9 months, 38 transfusion-dependent patients with beta-thalassemia, ranging in age from 3.4 to 19.1 years, were observed for serologic evidence of viral infections, by the collection of serial serum samples. Seventy-six age-matched healthy subjects, two for each patient, were followed as controls. Samples taken at the beginning, middle, and end of the study were tested against 18 viral antigens by complement fixation (CF). In addition, tests for antibodies to HIV, Epstein-Barr virus, hepatitis A virus, and markers for hepatitis B virus were performed. When changes in the antibody titer on CF tests (greater than or equal to 2-fold increase or decrease) or persistently high titers (greater than or equal to 64) were revealed, specific enzyme immunoassays (EIAs) for IgM and IgA antibodies were performed concomitant with CF tests in all sera. When symptomatic infections occurred, viral cultures and/or direct detection of antigens were carried out by immunofluorescence methods, EIA, or latex agglutination tests. Thalassemic patients and controls had similar (p greater than 0.05) overall rates of serologically confirmed viral infections (53 versus 132), but the former group had a higher (p less than 0.01) incidence of cytomegalovirus (CMV) infections (9 versus 4). CMV infections were associated in the thalassemic patients with hepatitis (2 cases), lymphadenitis (2 cases), and upper respiratory tract infection (1 case), while the remaining cases of CMV had a subclinical course. Moreover, the thalassemic patients had a lower (p less than 0.01) incidence of symptomatic infections (27 versus 110) than controls. Therefore, this study showed that both symptomatic and subclinical CMV infections may occur often in thalassemic patients, who otherwise have subclinical viral infections at an overall rate similar to that in healthy subjects.
