An outbreak of hepatitis in plasma donors occurred in a village of Hebei Province in the period of September to October 1985. The morbidity rate was 40.0% (26/65) in the plasma donors, which was significantly higher than that in whole blood donors (1/88) and in persons who were not blood donors (1/400). One to one paired survey was carried out, and the incidence was 46.4% (26/56) in the plasma donors, while there were no such outbreak in the control group. The distribution of cases showed positive correlation with the number of plasma donors from the production brigade. No secondary infection was found in their families. The peak of outbreak was about 2 months later than the peak of plasma donation. 26 cases of hepatitis in plasma donors all showed negative results for anti-HAV IgM, HBsAg, anti-HBC IgM, anti-CMV IgM and anti-EBV IgM. Sera of 25 cases were selected and sent to CDC, USA to confirm with Chiron C100 reagent. 24 cases were anti-HCV positive. This outbreak of hepatitis was demonstrated to be related to cross contamination during plasma donation.

During the 20th century, tuberculosis has been the most prevalent and most harmful disease in Japan. Enormous medical researches have ever been performed to conquer the disease. Nevertheless tuberculosis has left various somatic and psychological residues on vast convalescents. On the other hand, researches to conquer tuberculosis have made considerable contribution to other fields of medicine. 1. Somatic and psychological residues on convalescents from tuberculosis. Chest x-ray findings, cardio-pulmonary disturbance, secondary infection, serum-hepatitis due to mass transfusion during the chest surgery, streptomycin-deafness and psychological disorder. 2. Sequelae of phthisiology. a. In the field of basic medicine. Respiratory physiology, immunology and genetic pharmacology. b. In the field of epidemiology. Methodology to control the disease. c. In the field of clinical medicine. Chest x-ray diagnostics, bronchoscopy, thoracoscopy, randomized controlled trial, regimens of chemotherapy, open chest surgery, anesthesiology, treatment of respiratory failure, informed consent, terminal care and cooperative study system. d. In the field of rehabilitation. Medical, vocational and social rehabilitation of the handicapped. e. In the field of public health. Comprehensive control system of the chronic disease. Smallpox has been eradicated, but the elimination of tuberculosis is still far away. Studies as excellent as past ones should intensively be carried out.

While recognizing the fact that the use of strict hygienic techniques, disposable materials and quality control are essential for sterilizing instruments, vaccination still remains the most efficient way to combat infection. In this article, the authors discuss the principle problems associated with the use of vaccines and especially as they relate to the dental office. Hepatitis B is certainly of interest to all dentists and their personnel, especially since its primary mode of transmission is by contact of blood with the skin and the mucosa. The two forms of vaccines presently available, are derived from the human plasma of carriers or from yeast and cause a genetic reaction which produces hepatitis B virus antigens. These vaccines protect at least over 90% of all healthy individuals and do not generate any secondary infection or unfavorable reactions. Faced with the reality of hepatitis B, it is very wise to remember that it is BETTER TO BE VACCINATED THAN TO HAVE TO LIVE WITH THE EFFECTS OF HEPATITIS.

We report our experience with 29 symptomatic herpesvirus infections occurring during the course of 87 pediatric transplant procedures performed over the 10-year period, 1973 to 1982. The yearly attack rate ranged from 0.05 to 0.40 case per cumulative patient years at risk. A greater proportion (9 of 14) of children who received more than 10 units of whole blood or packed red blood cells prior to transplantation developed a viral infection compared with those given 10 transfusions or fewer (8 of 25) (P = 0.10). Fever occurred in 22 (76%) children, pulmonary disease in 8 (28%), hepatitis in 11 (35%), leukopenia in 7 (24%), thrombocytopenia in 9 (31%) and central nervous system disease in 3 (10%). Herpesvirus infections were responsible for allograft loss in 7 (24%) patients. However, no differences in the actuarial graft survival curves were noted for transplants performed since 1979 in children with and without viral infection. The etiologic viral agents were cytomegalovirus in 19 (65%) episodes, herpes simplex virus in 8 (28%), Epstein-Barr virus in 2 (7%) and varicella-zoster virus in 2 (7%). Cytomegalovirus-infected patients were younger and more commonly developed primary infection compared with children with herpes simplex virus disease who were more likely to have secondary infection and to manifest a mucocutaneous vesicular rash. We conclude that the etiologic agents and clinical features of herpesvirus infections are similar in pediatric and adult renal allograft recipients. Moreover except for distinctive syndromes such as mucocutaneous vesicular eruption or a central nervous system lymphoma, the various herpes-viruses cause clinically indistinguishable illnesses in pediatric transplant patients with similar end organ involvement and untoward renal consequences.

The detection of hepatitis B viral antigens and the hepatitis delta viral antigen on liver section is currently facilitated by the production and marketing of good quality antisera and revelation systems. Moreover, the routine application of these techniques in histology departments has become more widespread. The detection of HBs and HBc antigens may be useful in the diagnosis of chronic hepatitis. It allows evaluation of replication of HBV (in the same way as HBe antigen and serum DNA) and the examination of a liver needle biopsy should include, in addition to analysis and classification of the lesions, tests for the presence of these antigens. The detection of the delta antigen is particularly useful for the diagnosis of acute hepatitis delta (in cases of co-infection or secondary infection). On the other hand, it is disappointing for the diagnosis of chronic hepatitis delta.

Abrupt increases of alanine transaminase were observed in 6 of 23 non-treated, male homosexuals with chronic hepatitis associated with hepatitis B virus. Before this occurrence, all subjects had hepatitis B e antigen (HBeAg) and elevated DNA polymerase activity. Within 3 months, HBeAg was nondetectable in 3 subjects and elevated DNA polymerase disappeared in 4. These serologic events were not always sustained, however. In 3 subjects, reactivation of hepatitis B virus infection occurred within the subsequent 6-month period. Serologic testing for cytomegalovirus, Epstein-Barr virus, delta agent, and hepatitis B surface antigen (HBsAg) subtype showed that episodes of clearance and reactivation were not explainable by secondary infection with these agents or infection with a different HBsAg subtype. Spontaneous clearance and reactivation of hepatitis B virus infection may commonly occur among male homosexuals with chronic type B hepatitis. These phenomena should be considered when evaluating the need for treatment or interpreting the results of investigations that use anti-viral therapy.

A method was developed for the early diagnosis of type A hepatitis. The method involved the detection of fecal antibody against hepatitis A antigen (HAAg). We followed 6 patients who contracted type A hepatitis in an outbreak for the fecal excretion of HAAg and antibody against HAAg (anti-HA) by immune electron microscopy. Fecal anti-HA appeared soon after the disappearance of HAAg, at around the zenith of serum transaminase, and persisted approximately 4 mo after the development of hepatitis. Fecal anti-HA was of IgA class, since it was completely absorbed by an anti-IgA column, but not affected by anti-IgG or anti IgM column. Owing to its early appearance and short duration, fecal anti-HA allows an early diagnosis of type A hepatitis by the test of a single specimen. Fecal anti-HA would be assumed to herald the termination of the period during which patients should be segregated from the community to prevent secondary infection.

Plasma soluble tumor necrosis factor receptor (sTNFR) was detected by radioimmunoprecipitation-polyethylene glycol assay in 64 patients with viral hepatitis B. The levels of two distinct receptors (sTN-FR1 and sTNFR2) were significantly higher in chronic severe hepatitis (CSH) followed by chronic active hepatitis (CAH), chronic persistent hepatitis (CPH), and acute hepatitis (AH) or controls (P < 0.01). A more markedly increased sTNFR was observed in patients with high SB (> 342 mumol/L), low Pa (< 20%), and secondary infection or fatal outcome. For patients with 20% below of sTNFR levels, the increase of TNF was proportional to that of sTNFR. But, for patients with exceeding 20% of sTNFR, the ratio of TNF/sTNFR became higher. The ratio of TNF to sTNFR may be greatly indicative to determine the clinical severity and outcome. Administration of sTNFR could prevent the adverse pathologic sequence caused by the exaggerated TNF and open a new therapeutical field.

A total of 762 cases of viral hepatitis admitted to the two teaching hospitals of the Third Military Medical College were used for study. They were divided into two groups depending upon whether corticoid treatment was given. As the result of cRR = 6.06, chi 2 = 174.16, P < 0.01, it is obvious that the corticoid therapy is a risk factor for the secondary infection in patients suffered from viral hepatitis. For getting rid of the interference of confounding factor and interaction a stratified analysis was performed. These patients were again divided into severe type and moderate type according to the severity of the disease. The results of stratified analysis were aRR (F) = 3.05 and aRR (F) = 1.48, cRR > aRR. These findings demonstrated that the degree of severity of patients played a primary role in the secondary infection of hepatitis and showed that the confounding factor was present. On the other hand, the result of aRR (F) not equal to aRR (F) indicated that the interaction also existed simultaneously. This study suggests that special attention should be paid to maintain and increase the level of immunological defence function in patients with hepatitis. And, it is necessary to restrict the indiscriminate usage of corticoids, particularly in severe patients, for preventing nosocomial infection.

Infection with herpes simplex virus (HSV) is a common worldwide problem. Primary infection with HSV-1 rarely causes significant problems although widespread involvement in atopic eczema can be life-threatening as may associated encephalitis. Keratoconjunctivitis, pharyngitis and hepatitis can also complicate primary infection. Twenty to 40% of the population at some stage have recurrent orolabial infections with HSV although in only 1% of these cases is this recurrence severe. Recurrent erythema multiforme appears to be associated with HSV-65% of patients are thought to have preceding herpes labialis. Many primary and recurrent infections with HSV-1 require little more than topical antiseptic therapy to control secondary infection. Systemic acyclovir, however, is indicated in various situations including complicated primary infection, infection in neonates, eczema herpeticum, HSV infections in the immunocompromised, and recurrent erythema multiforme. In the latter, prophylactic treatment with 6 months acyclovir appears to be effective.
