During the period 1986-1988, the expression of anti-HDV in different high-risk groups and its clinical impact on patients with HBV-related chronic liver disease and hepatocellular carcinoma was investigated in Iran. Using the ELISA technique, we observed a 2.5% anti-HDV positivity in asymptomatic chronic HBsAg carriers (3 of 120); in hemophiliacs, two of six HBsAg carriers were positive for anti-HDV and zero of 50 anti-HBs positives. Anti-HBs positive dialysis patients were positive for anti-HDV in 2.0% of the cases (1 of 50), whereas the rate of anti-HDV positivity was 44.5% in hemodialysis patients positive for HBsAg (16 of 36). The figures were comparable in HBsAg positive patients with chronic active hepatitis and cirrhosis (49.2%; 31 of 63). Moreover, anti-HDV was detected in five of eight patients with hepatocellular carcinoma. These data indicate the endemicity of delta infection in Iran. The increased incidence among hepatocellular carcinoma patients is an interesting finding to be further investigated with larger groups of patients in this region.

The prevalence of anti-HCV, anti-HDV and of HBV markers has been investigated in a series of 209 consecutive patients (age 18-74 years) with chronic liver disease. Among 155 HBsAg negative patients (53 chronic hepatitis cases and 102 cirrhosis cases), anti-HCV were found in 69% of the cases. 67% of the 155 patients also carried anti-HBc, with no difference between patients positive or negative for anti-HCV. Among the 54 HBsAg positive patients, 10 (18.5%) also had anti-HCV, 22 (40.7%) were anti-HDV positive and 12 (22.2%) had serum HBV-DNA. One patient had concomitant anti-HDV and anti-HCV and another presented anti-HCV and serum HBV-DNA. 21/54 patients had liver cirrhosis on presentation and among these 17 (81%) were anti-HCV and/or anti-HDV positive. On the whole, 123/209 patients had liver cirrhosis on presentation and in 107 of them HCV infection may have played a role.

Ten years ago hepatitis B virus (HBV) was thought to be a unique virus, not included in any known family of viruses. Following the discovery of a number of HBV-like viruses that infect birds and mammals, the existence of a new family known as hepadnaviridae has been confirmed. Hepadnaviruses are small hepatotropic viruses that have a characteristic partially double stranded genome, exhibit a narrow host range and replicate by reverse transcription. The family currently comprises six viruses of which human hepatitis B virus is the prototype member. Other members include woodchuck hepatitis virus (WHV), ground squirrel hepatitis virus (GSHV), tree squirrel hepatitis virus (TSHV). Peking duck hepatitis B virus (DHBV) and heron hepatitis B virus (HHBV). Candidate members of the family include kangaroo hepatitis virus (KHV) and stink snake hepatitis virus (SSHV). In humans, infection with HBV is associated with a wide spectrum of clinical conditions including acute and chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC). Infection with HBV is endemic throughout much of the world and the virus is maintained by the enormous reservoir of over 300 million chronic carriers. For almost 20 years experimental work on hepadnaviruses has been carried out using either natural hosts or cultured cells that were capable to support synthesis of a few viral gene products but unable to execute a complete cycle of virus replication. In this article, we have attempted to summarize the efforts made towards understanding the biology of hepadnaviruses, the nature of their infections and their association with primary liver cancer.

With the advances that are being made in many areas of medicine, the surgeon must be familiar with infectious diseases of the peritoneal cavity, which have increased in scope and complexity. In addition to the surgical management of secondary peritonitis resulting from perforation of the gastrointestinal tract, the practicing surgeon may be called on to manage patients with cirrhosis with infected ascitic fluid as well as patients undergoing peritoneal dialysis with infected dialysis fluid. In addition, there is increasing recognition of a group of patients with persistent intraabdominal sepsis or tertiary peritonitis in whom infection is associated with multiple systems organ failure and general depression of the immune system. This article endeavors to present an overview of the diagnostic and therapeutic approaches to these disease entities.

No other infectious diseases in the field of otolaryngology cause rapid and lethal course than cervical abscess. A case of cervicomediastinal abscess secondary to acute tonsillitis was presented. The patient was a 43-year-old male with liver cirrhosis and primarily had the treatment of tonsillitis. The complication of duodenal perforation caused marked general deteriotation, and cervical abscess occured. Immediately after transfer to our department, he was treated by cervical drainage, laparotomy and chemotherapy. However, hepatic failure occured, and he died of sepsis on the 16th day after the onset of tonsillitis. Cervicomediastinal abscesses were classified according to severity in Stage 1-4. 34 cases of advanced cervical abscess were reported in Japan from 1976 to 1989. These cases were analyzed statistically in terms of primary focus of infection, surgical procedures, clinical isolates and chemotherapy, etc., and following results were obtained. 1) Primary focus; approximately 50% was due to the infection of the tonsills and the pharynx occupied about 50%, and the odontogenic infections, approximately 40%. 2) Surgical procedures; the neck doranaige approaching through the vertical incision resulted more effective. 3) Clinical isolates; aerobes and anaerobes accounted for 50% each of all strains. alpha-Streptococcus was predominant among aerobes, and Peptostreptococcus and Bacteroides were predominant among anaerobes. In order to confirm pathogenic bacteria of cervical abscess, clinical isolates of peritonsiller abscess and mandibular ostesis were compared with those of cervical abscess, because these infections are primary infectious diseases of cervical abscess.(ABSTRACT TRUNCATED AT 250 WORDS)

A group of 70 chronic alcoholics--65 men and 6 women--has been studied. HBsAg was found in 11 (16%), and at least one marker of HBV infection was present in sera from 31 (44%) persons, these results being significantly higher than in a matched control population. The commonest single histological patterns were: steatosis (18 cases), and alcoholic hepatitis (18 cases), followed by normal liver (14 cases) and chronic active hepatitis (12 cases). Cirrhosis was diagnosed in only 4 cases. Five cases of chronic active hepatitis could be attributed to infection with HBV or HDV; in the remaining 7 cases the etiology was unclear. Infection with HBV seems to play an important role as the cause of liver disease among alcoholics in Poland, and chronic active hepatitis of various etiology may be an important form of liver pathology among them.

As part of an ongoing epidemiologic study, the death rate and causes of death during 1975 through 1984 were determined in Pima Indians who resided in the Gila River Indian Community (GRIC) in 1965 and later. Death certificates were available for 677 of the 681 deaths. In 78% of the deaths, the underlying cause recorded on the death certificate agreed with the cause determined after review of all available relevant records. The age- and sex-adjusted average annual death rate for the GRIC population (1639/100,000) was 1.9 times (95% CI 1.7-2.0) the 1980 rate for the U.S. all races (878/100,000). In Pima males, whose death rate was substantially higher than that of Pima females, the age-adjusted death rate was 2.3 times that in U.S. males, all races. Moreover among males 25-34 years of age, the Pima death rate was 6.6 times that for the U.S. all races. Diseases of the heart and malignant neoplasms caused 59% of U.S. deaths in 1980, but only 19% of GRIC deaths. By contrast, the age- and sex-adjusted mortality rate in the GRIC Pima was 5.9 times the rate of the U.S. all races for accidents, 6.5 times for cirrhosis, 7.4 times for homicide, 4.3 times for suicide, and 11.9 times for diabetes. Tuberculosis and coccidioidomycosis were important causes of death in the Pima, for whom infectious diseases was the tenth leading cause of death. The findings indicate that programs to improve the adverse mortality experience of the GRIC population should emphasize factors related to fatal accidents, alcoholic cirrhosis, homicide, suicide, diabetes mellitus, and infectious diseases. Young Pimas, especially the males, should be the primary focus of such preventive efforts. These findings and recommendations probably apply to many Native American populations.

The transmission of infectious diseases, mainly hepatitis B, non-A non-B and HIV infection, was the major complication of replacement therapy in hemophiliacs before the introduction of virus inactivated concentrates. The clinical relevance of transfusion associated infections in 43 hemophiliacs treated with different coagulation preparations during an observation period from 1978 to 1986, is discussed. Up to 1981, 38 hemophiliacs have shown hepatitis B seroconversion; 20 of them had a permanent increase in ALT levels. Only two among the five seronegative hemophiliacs showed an immune response to vaccination against hepatitis B. During the observation period 13 hemophiliacs contracted clinical non-A non-B hepatitis. Ten hemophiliacs have been HIV infected. Both hepatitis B and HIV infection occurred more frequently in hemophiliacs treated with foreign concentrates. One patient died of liver cirrhosis, another of AIDS. Since 1986. Swiss hemophiliacs have only been treated with virus inactivated concentrates: therefore no further HIV infections or hepatitis have been observed. Different methods of virus inactivation and factor VIIC purification are discussed. Since factor VIII yield is very low in the ultrapure and virusfree concentrates, a worldwide shortage of factor VIII concentrates is going on. It remains to be expected whether the availability of recombinant factor VIIIC will resolve these problems in the near future.

During the last eighteen years (1970-1987) at the Infectious Diseases Clinic of the University of Pavia, Ospedale Policlinico S. Matteo, IRCCS, Pavia (referral Center for hepatitis in our district: 502534 inhabitants) we observed 4238 patients (2706 M = 63.8%; 1532 F = 36.2%) admitted with presumptive diagnosis of hepatitis. The male to female sex ratio was 1.78 and average age was 38 (1-90) years. Acute viral hepatitis was diagnosed in 3238 patients (76.4%), 1960 of which were males (60.5%) and 1278 (39.5%) females, with an average age of 35 (1-88) years. The possible route of transmission was: drug addition in 487 patients (15%), blood transfusion in 464 (14.3%), other (sexual, professional, familiar) in 332 (10.3%), unknown in 1955 (60.4%). Chronic hepatitis (CH) was diagnosed according to the European Association for the Study of the Liver (EASL) and to the International Association for the Study of the Liver (IASL) in 848 patients (20%), 704 M(83%) and 144 F (17%) with an average age of 48 (2-90) years. 463 patients (54.5%) were biopsied during admission, 385 (45.5%) received definitive diagnosis by clinical and previous histologic records. CAH was found in 268 (57.9%), CPH in 161 (34.8%) and CLH in 20 (4.3%) patients. Other liver diseases (steatosis, cirrhosis, HCC) were identified in 152 subjects (3%). The prevalence of A, B, NANB and Delta hepatitis virus and HI virus in the acute disease was respectively of 5.4%, 54.8%, 33.9%, 0.28% and 0.77%. In CH the HBV aetiology accounted for 49.1%, NANB virus for 44.5%, co/super infection with HDV for 15%. Among factors involved in pathogenesis of chronic hepatitis we focused attention on drug addition which was found in 129 (28.7%) patients, blood transfusion in 70 (15.6%), HIV infection in 35 of 166 (21.1%). The data still demonstrate the high prevalence of HBV aetiology of CH and existence of co-factors in the pathogenesis of chronicity. The lack of markers for NANB infection persists as the main problem in the diagnosis of liver disease. This work was supported by grant 40% from M.P.I.: "Epatiti virali acute e croniche"....

Radioimmunoassay and enzyme-immunoassay were used to study the detection rates of HBsAg and anti-Delta in blood donors and subjects at high risk of infection with hepatitis B (HB) in the Byelorussian SSR. The republic was found to belong to the region with a moderate prevalence of HB and low prevalence of delta-virus infection. The detection rate of anti-delta antibodies in individual population groups depends on the level of HBsAg carrier state and is closely associated with prolonged treatment in medical institutions. Patients with tuberculosis, rheumatoid arthritis, diabetes mellitus, and cirrhosis of the liver are important reservoirs of HB and delta-virus infection for a region with moderate prevalence of HB virus and low prevalence of delta-virus. Infection with delta-virus is very important in unfavourable outcomes of acute and chronic viral hepatitides in the region.
