The epidemiologic, clinical and laboratory features of 40 adults with acute viral hepatitis type B were compared with those of 40 adults with hepatitis non-B. Overall, the clinical presentations were remarkably similar and the etiology could not be determined in individual cases. An exception to this was that all post-transfusion cases in this series were affected by hepatitis B. Men predominated in both the hepatitis B and non-B groups. There was a tendency to seasonal clustering in summer/autumn in both groups. Hepatitis B patients were significantly older and 59% of them had a history of possible parenteral exposure during the six months preceding admission. On the other hand 76% of patients with hepatitis non-B had no apparent parenteral exposure. Dental treatment, injections and contact with jaundiced patients were recorded in both groups and were therefore of no value in determining the exact etiology in individual cases. Fever was more common in hepatitis non-B, while the onset of the disease was insidious and afebrile in 80% of patients with hepatitis B. As a group, patients with hepatitis B had more extensive liver injury and a more prolonged clinical course, and the only fatality was in this group. Cholestatic features were rare and extrahepatic immune complex disease was extremely uncommon in both hepatitis B and non-B.

In 1983, the regulation on reporting transmissible diseases was extended. At that time, the doctors were obliged to report all cases of acute viral hepatitis to the Cantonal physician. The Federal Office of Health commissioned a statistical evaluation of the reports from the years 1984 to 1987. Of the 4543 reports analysed, 40% relate to hepatitis A, 47% to hepatitis B and 7% to non-A non-B hepatitis. Men suffered hepatitis more frequently than women, with the exception of the non-A non-B hepatitis, where the sexes are roughly equally represented. Adolescents and young adults are the most frequently affected age group for all types of hepatitis. Those dependent on drugs have a particularly high risk of infection for all types of hepatitis. The cases of hepatitis occurring after journeys abroad are even more significant in terms of numbers. The medical personnel can no longer be regarded as a high-risk group. An age-standardized comparison shows that, with regard to hepatitis B, the risk for men in medical professions is the same as the average risk for all men, while the risk for women is still slightly higher than that for the female population as a whole.

Transfusion of homologous blood components is associated with immunological (incompatibility, alloimmunization, immunosuppression) and infectious risks (hepatitis, cytomegalovirus, HIV and other agents). Endoprosthetic surgery of the hip and knee frequently requires transfusion. Preoperative deposit of autologous blood can reduce homologous transfusion requirements. The simplest method is liquid storage of whole blood. In order to re-examine the efficiency of our present scheme of preoperative deposit, we studied patients scheduled for endoprosthetic surgery with respect to the amount of blood deposited, stimulation of erythropoiesis, and homologous blood requirements at the time of operation. PATIENTS AND METHODS. Sixty-seven consecutive patients (33 men, 34 women) scheduled for endoprosthetic replacement of hip or knee or for revision arthroplasty of the hip were studied. Patients with anemia, coagulopathies, coronary heart disease, severe obstructive or restrictive pulmonary disease, cerebral sclerosis, syncopes and seizures were excluded from preoperative deposit. Patients deposited 450 ml at weekly intervals, with occasionally slightly higher or lower volumes. A patient was temporarily deferred when the hemoglobin concentration prior to donation fell below 11 g/dl. Blood was collected in CPDA-1 buffer. The aim was a deposit of three units. In patients undergoing exchange reoperation of a total hip arthroplasty, intra- and postoperative autotransfusion with a cell separator was employed in addition to preoperative donation. RESULTS. The age of the patients ranged from 43 to 83 years (mean +/- SD: 61.2 +/- 9.1). The differences between men and women with respect to height (172.9 +/- 6.8 vs 160.6 +/- 7.4 cm; p less than or equal to 0.001), weight (75.7 +/- 11.2 vs 69.1 +/- 11.0 kg; p less than or equal to 0.05), calculated blood volume (p less than or equal to 0.001), and erythrocyte volume prior to donation (p less than or equal to 0.001) were significant. A total of 185 units was deposited. Men donated 1350 (450-1970) ml blood (median, range) and women 1260 (340-1450) ml (p less than or equal to 0.01). Hemoglobin concentrations decreased significantly from an average of 14.7 g/dl in men and 13.8 g/dl in women prior to donation to 13.4 g/dl and 12.3 g/dl preoperatively (p less than or equal to 0.0001 for both groups). The donation was not associated with serious complications. For 4 patients the scheduled operation was deferred for a longer term. Forty-six patients (23 men, 23 women) underwent total hip arthroplasty, 12 (4 men, 8 women) exchange of total hip arthroplasty, and 5 (3 men, 2 women) endoprosthetic knee surgery. In total hip arthroplasty men required 0 to 500 ml homologous packed red cells (median=0), women 0 to 1250 ml (median=0;p less than or equal to 0.05). Thirty-nine (69.6%) of the patients, 19 (82.6%) men and 13 (56.5%) women, did not require homologous transfusion.(ABSTRACT TRUNCATED AT 400 WORDS)

During a period of one year all of 105,724 blood donations were tested for Australia (Au) antigen and its antibody by rapid immunoelectro-osmophoresis-86 (1 in 1,229) were positive for antigen and 67 (1 in 1,578) positive for antibody. Second donations by previously negative donors reduce the overall incidence of positives. Men prisoners have a significantly higher incidence of Au antigen (1 in 153) than non-institutionalized men (1 in 803). The latter have a significantly higher incidence of antigen than women (1 in 2,019). Only one antigen-positive donor was incubating acute viral hepatitis. Failure to detect one strong and one weak antigen was responsible for two cases of posttransfusion Au-antigen-positive hepatitis.

The frequency of cirrhoses drastically increased in the seventies. This increase was predominantly due to an augmentation of alcoholic cirrhosis in men. Cirrhosis is significantly more wide-spread in men than in women. Most of the cirrhoses in women are of unknown origin. Morphologically, the alcoholic cirrhoses are of the micronodular types in their great majority. Combined with HBsAg positivity, the macronodular type is most frequent. The classification in micro- and macronodular cirrhoses do not imply a different etiology but it may indicate different stages in cirrhosis of identic origin. Histologically, the signs of alcoholic hepatitis particularly help to trace back the alcoholic etiology. If HBsAg can be detected and the margins of the pseudolobules are moth- eatenlike , this speaks for a hepatitic origin. The lowest average age was observed in cases of alcoholic cirrhoses, the highest in HBsAg positive cirrhoses of women. Men suffering from cirrhosis die earlier than women. In the case of alcoholic origin, the bulk of the cirrhotic livers are eutrophic while, beside HBsAg positivity, the atrophic livers are prevailing. The two most frequent environmental causes of cirrhosis are alcoholic beverages and hepatitis. Better exploration of the environmental factors and clearing up the origin of cryptogenic cirrhoses are essential tasks of the future.

Ninety-two British, caucasian, alcoholic patients with liver disese were grouped on the basis of hepatic histology into fatty change, hepatitis with or without cirrhosis, and cirrhosis alone. Men with alcoholic hepatitis with or without cirrhosis showed an increased incidence of the histocompatibility antigen HLA-B8 (P less than 0.02). Increased measles antibody titres were found in patients without cirrhosis with or without hepatitis and were associated with the B8 phenotype in both sexes. Rubella antibody titres and percentage DNA-binding were raised in patients with cirrhosis and showed no association with the B8 phenotype. Concentrations of IgM and IgA were were raised in patients with stetosis and with hepatitis, while in patients with cirrhosis IgG concentrations were also increased. Low titres of autoantibodies were found in all histological groups. It is possible that the development of hepatitis in response to alcohol abuse may be influenced, at least in men, by a gene linked to the B locus. Otherwise, immune processes associated with alcohol-related liver disease are probably secondary phenomena.

Hypobetalipoproteinemia (HBLP) is characterized by plasma concentrations of apolipoprotein B (apoB) and low density lipoprotein cholesterol (LDL-C) below the fifth percentile. Some forms of HBLP have been shown to be due to truncated forms of apoB-100. A total of 3873 subjects participating in the Framingham Offspring Study had LDL-C levels measured every 4 to 5 years throughout a 25-year period. Seventy-five subjects were identified with persistent HBLP, defined as an LDL-C <70 mg/dL on at least 2 observations, for a prevalence of 1.9% in this population. Compared with subjects with LDL- C >/=70 mg/dL, subjects with HBLP had significantly lower mean levels of total cholesterol, LDL-C, triglyceride, and apoB; higher levels of high density lipoprotein cholesterol; and a higher prevalence of the E2/E3 genotype: 38.7% versus 10.9% (P<0.001). Men with HBLP had a larger mean LDL particle size than did men with an LDL- C >/=70 mg/dL. One individual had a truncated apoB as a cause of HBLP, for a prevalence of 0.03%. Medical causes of HBLP included 2 cases of Crohn's disease, 1 of hemochromatosis, and 1 of hepatitis. Three subjects with HBLP developed coronary heart disease, for an incidence of 4% compared with 5% in those with an LDL- C >/=70 mg/dL (P=NS). The incidence of cancer was 8% in those with HBLP compared with 4% in those with an LDL-C >/=70 mg/dL (P=0.21). In conclusion, a truncated apoB was a rare cause of HBLP, whereas the E2/E3 genotype was a much more common cause. A large prospective study is needed to evaluate the incidence of cancer and atherosclerosis in subjects with HBLP.

The objective of the research was to determine the demographic, sexual and social risk factors associated with condom use in 7,089 multi-partnered men attending the Sydney Sexual Health Centre. A review of computerized medical records from 1991 to 1999 was carried out. Males with two or more partners in the last three months were divided into three condom use groups: consistent, sometimes and never. Men reporting sex with men (MSM) were more likely to use condoms than men having sex with only women (p=0.001). HIV positive men were more likely to use condoms consistently than those who were negative (p=0.001). In HIV negative non-hepatitis-B carriers, factors independently associated with inconsistent condom use included alcohol consumption, intravenous drug use (odds ratio (OR) 0.6 (95% confidence interval (CI) 0.47-0.77)) and being married (OR 0.2 (95% CI 0.21-0.31)). Factors associated with consistent condom use were MSM (OR 1.8 (95% CI 1.26-2.49)) and having three or more partners in the last 3 months (OR 2.4 (95% CI 2.023-2.83)). In the 508 hepatitis B carriers, consistent condom users were less likely to be married or intravenous drug users (OR 0.4 (95% CI 0.23-0.85)). In the 200 HIV antibody positive men, those with three or more partners were less likely to be consistent condom users than those with two (OR 0.3 (95% CI 0.11-0.82)). The conclusions are that a small number of HIV positive men report unsafe sex with multiple partners. Health promotion activities should be directed at this group.

Men entering prisons have high rates of sexually transmitted disease (STD), hepatitis, and HIV. This study sought to determine the acceptability and feasibility of screening for STD and hepatitis in young men released from prison. Participants were interviewed six months after release and offered free screening. Of 42 (56%) eligible men who participated in the qualitative interview, 33 (79%) provided at least a blood or urine specimen. Eight of 33 (24%) men tested had chlamydia, trichomoniasis, hepatitis B or C virus (HBV or HCV). Three of 32 (9%) had chlamydia, three of 32 (9%) had trichomoniasis, two of 28 (7%) had prior syphilis, and two of 28 (7%) had HCV. Of 28 tested for HBV, six (21%) were immune, two (7%) had chronic infection, and 20 (71%) were susceptible. Barriers to screening included lack of forewarning, inconvenience, and insufficient incentive. In conclusion, screening for STD and hepatitis among former inmates can be acceptable and feasible. Forewarning, reducing the time burden, and providing monetary incentives may increase screening rates.

The aim of the study was to determine the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infection among HIV positive patients, to identify most relevant risk factors of co-infection and develop preventive interventions. Study participants were voluntary individuals 18 years of age or older recruited from AIDS Center VCT unit in Tbilisi, Georgia. Eligibility criteria of participants were: HIV positive result confirmed by western blot; age; and voluntary participation. Total 175 patients undergo interview with specially designed questionnaires. Most of the participants were male (71.4%), age range of HIV positives varied from 20 to 77 years old. Prevalence of HCV among HIV positive patients is high. Almost half (48.57%) HIV positive patients are co-infected with HCV. Men were more likely than women co-infected with HCV (60.80% and 18% accordingly). Major risk factor of male co-infection was related to drug use, needle and injection equipment sharing. Prevalence of HCV among injecting drug users was (73.40%). Drug users had 3.25 times more risk (PR 3.25; 95%CI; CL--1.89-5.26; p<0.01) to be infected with HCV compare non IDUs. Prevalence of being infected with HBV (Anti-HBc) among HIV positives was 43.42% (76/175) and the prevalence of Chronic HBV (HBsAg positive) was 6.86% (12/175). Prevalence rate of HBsAg among IDUs was 8.51% and among non IDU participants 5.26%. Triple infection (HIV, Hepatitis C and chronic form of Hepatitis B--HBsAg) was among 9 patients (5.14%). Infections were associated with injection drug use (88.88%) and mostly were related to share of needles/syringes and other injecting medical equipment. Transmission of HBV and HCV by sexual contact was not observed among those 9 participants. High risk behavior among HIV positive participants mostly related to drug use and unprotected sex with non regular partners. Other risk factors for Hepatitis transmission were associated with invasive medical manipulations, blood transfusion, surgery, abortions and etc. None of cases of HIV, or Hepatitis (B, C) transmission through medical manipulations can be documentary proved based on those research data.
