To determine effects of circulating hepatitis B surface antigen (HBsAg) on patient survival following renal transplantation, we studied 168 recipients of cadaveric grafts in whom HBsAg status was defined at transplantation by comparison of survivorships determined by actuarial life-table methods. Survival in HBsAg-positive recipients, as compared with those who were HBsAg-negative at the time of transplantation, was markedly diminished. Although graft survival appeared to be favored in the HBsAg-positive group in the early posttransplant period, the apparent protective effect was lost at nine months after grafting and thereafter, due to increased mortality in the HBsAg-positive recipients. Deaths in the antigenemic subjects were principally due to infections other than hepatitis and to cardiovascular events. We conclude that preexisting HBs antigenemia forebodes an ominous outcome for immunosuppressed renal transplant recipients, although hepatic disorders do not account for most deaths.

Review of the clinical records of 103 patients participating in a community-blood-bank-sponsored autologous transfusion program confirmed the safety of autologous blood and the practically of such a community-centered program. There were no transfusion reactions, increased morbidity, or reports of hepatitis among the autologous donor-patients. A previously unobserved phenomenon was that surgeons tended to transfuse less blood to patients who had autologous blood available, rarely exceeding the number donated, although this varied from one to three units for similar surgery. Only eight of the 103 patients intentionally received a transfusion with homologous blood in addition to their autologously donated blood. Patients, their physicians, and the blood bank can all benefit substantially from such a program.

From September 1976 through March 1978, we investigated 11 outbreaks of non-B viral hepatitis associated with Louisiana day-care centers. The outbreaks included 168 cases, most of which were erroneously considered "sporadic" cases of non-B viral hepatitis prior to the investigations. Thirteen percent of all non-B viral hepatitis cases reported in the New Orleans metropolitan area during 1977 were associated with one of the outbreaks. Most of the cases in each outbreak and 85% overall were in older, usually adult, contacts of children attending the day-care centers. Within the household, parents appeared to be at greatest risk, particularly those who had 1- to 2-year-old children in the day-care center. Day-care center outbreaks of non-B hepatitis are easily overlooked and may be more widespread than is currently appreciated.

Five patients with hypertension died as a result of myocarditis. Three were treated with methyldopa and hydrochlorothiazide, two with methyldopa alone. Their ages ranged from 30 to 71 years. In all instances death occurred suddenly, and myocarditis was not suspected clinically. The inflammatory changes in the hearts of these patients were most consistent with a hypersensitivity reaction. Additionally, there was hepatitis consistent with hypersensitivity in four of the cases.

The e antigen HBeAg and its antibody anti-HB, have been said to be predictive of chronicity and resolution, respectively, in viral hepatitis. We found, as have others, a specific association with hepatitis B virus-induced disease. In addition, detectability of HBeAg in the acute phase of type B hepatitis was followed by a sixfold higher incidence of chronic hepatitis. Unfortunately, the prediction was erroneous in 65% of positive cases and 6% of negative cases. In chronic hepatitis, HBeAg did not necessarily disappear in advance of resolution, and its disappearance did not necessarily indicate resolution. Two patients with acute hepatitis progressing to chronicity were anti-HBe-positive in both phases, as were seven (5%) with chronic hepatitis. For individual patients, therefore, HBeAg and anti HBe are not prognostically useful indexes.

To define the epidemiologic features of occupationally acquired hepatitis B infection among physicians, we conducted a seroepidemiologic survey of physicians attending three American Medical Association conventions in 1975 and 1976. Of 1,192 participating physicians, 220 (18.5%) had serologic evidence of prior hepatitis B virus infection (positive hepatitis B surface antibody). The infection rate was higher among those practicing in urban communities; it increased with the number of years in practice; and among specialties, it was highest in pathologists (27%) and surgeons (28%). The serologic data demonstrated a changing pattern of viral hepatitis related to entry into the medical profession, with hepatitis B accounting for a majority of clinical hepatitis experienced after beginning medical practice.

Six of 106 undertakers (5.6%) gave a past history of hepatitis during their professional careers; this was no different from the frequency in a control group of 3,162 accountants (5.1%) who had no direct contact with blood. None of the undertakers or 210 blood donors matched for age, sex, and ethnic background had serum positive for hepatitis B surface antigen. Five undertakers (4.7%) had blood that was positive for antibody to hepatitis B surface antigen, compared with six of 210 (2.9%) in the control group; this difference was not statistically significant (P greater than .25). Thus, undertakers appear to be in a low-risk occupation with reference to acquisition of hepatitis B. Although the numbers are too small for statistical analysis, there appeared to be an increased exposure to hepatitis B in undertakers who take no preventive precautions. We recommend that the minimal precautions for undertakers be the wearing of gloves.

We performed a prospective study to assess the risk of patients acquiring infection following routine professional contact with two dentists incubating type B viral hepatitis. Serum samples from patients exposed during the six weeks before onset of hepatitis in the dentists were tested for hepatitis B surface antigen and for antibody to the antigen shortly after illness developed and again six months later. Household members of exposed patients served as a control group. None of the exposed patients or controls became ill with hepititis, and none developed antigen. Three of the 237 exposed patients developed antibody, as did four of the 245 controls. The difference between exposed patients and controls was not significant. These results do not support the hypothesis that these two dentists transmitted infection to their patients.

Investigation of an outbreak of hepatitis A among members of an adoption organization implicated recently arrived Vietnamese orphans as the source of infection. A serologic study disclosed a 27% prevalence of hepatitis B surface antigen among Vietnamese orphans and a 23.1% (6 of 26) prevalence of hepatitis B antibody among American children of adopting families. Five of the six antibody-positive American children were in families with HBsAg-positive orphans. Thus,healthy orphans from high hepatitis incidence areas may transmit hepatitis B, as well as hepatitis A, in the family unit.

Contaminated pressure monitoring devices recently have been implicated as a source of epidemic organisms in three outbreaks of nosocomial bacteremia, one outbreak of candidemia, and one outbreak of hepatitis. Measures necessary to prevent monitoring-related infections have not always been appreciated or taken. As a minimum, pressure monitoring devices should be sterilized between use with different patients; strict aseptic technique should be employed when setting up and using monitoring systems; and each patient's monitoring tubing, fluid, and monitoring devices should be changed at regular intervals.
