Interferon alpha is the only available therapy for patients with chronic hepatitis B. With interferon alpha 3-15 MU thrice weekly or 5 MU daily during 3-6 months one-third of the patients achieve seroconversion of HBeAg and HBV-DNA together with normalization of aminotransferases and slight improvement of histology. Loss of HBsAg is reported in a minority of responders during treatment, but increases during follow-up. Patients with baseline alanine aminotransferase of at least twice the upper limit of normal and low HBV-DNA concentration achieve the best response rates. HIV-positive patients with low CD4 counts and Asians are poor responders. As side-effects influenza-like symptoms are experienced by almost all patients. Mild leukopenia, thrombocytopenia and decreased hairgrowth are frequently reported. Severe depression, depersonalization and psychosis are reported in a small number of patients but tend to be poorly recognized in some studies. The decision whether dose reduction is indicated seems strongly related to the opinion of the investigator. Although long-term effects on the occurrence of cirrhosis and the development of hepatocellular carcinoma are not available yet, the achieved results are promising.

The use of the indicator "years of potential life lost" (YPLL) highlights the extent to which premature mortality in Puerto Rico is a predominantly male phenomenon. While men accounted for 58.6% of all deaths in 1987, they represented fully 71.8% of all YPLL attributed to the thirteen leading causes of death. The breakdown of YPLL by gender also underlines sex-specific differences in the causes of mortality. While accidents constitute the leading cause of premature death among men, malignant neoplasms take the lead among women. Similarly, homicides and cirrhosis are significant sources of years of life lost among males, while pneumonia/influenza and diabetes are higher priorities among females. These findings suggest that health promotion strategies need to be gender-specific in order to reach the right targets.

Alpha-interferon has emerged as the most effective agent for the treatment of chronic hepatitis when active replication of virus B, C, or D is present. Exogenous administration of human alpha-interferon, now possible through modern large-scale production methods, is associated with suppression of virus in blood. Amelioration of liver disease occurs in 35% of patients with hepatitis B virus and in 50% with hepatitis C virus with interferon doses of 30 and 10 MU per week, respectively, for 16-26 weeks; after therapy, persistent normalization of serum alanine aminotransferase is observed in 35% and 27%, respectively. Similar results have now also been reported for chronic hepatitis D. Enhanced response rates (greater than 50%) may be obtained by prolonged intermittent interferon therapy. Combination of interferon with another 'antiviral' agent (vidarabine, acyclovir, prednisone) has not increased therapeutic efficacy. Alpha-interferon induces side effects such as fatigue, flu-like syndrome, myalgia, and changes in mood and granulocytes. Patients with decompensated cirrhosis are particularly prone to bacterial infection and disease exacerbation and should receive lower doses. Interferon, when applied skillfully, induces the highly beneficial transition of active viral replication into viral latency, thereby greatly reducing infectivity, symptoms, and activity of the liver disease. Prevention of death from liver failure or hepatocellular carcinoma is to be expected.

We measured activities of alpha- and gamma-interferon simultaneously in 198 sera of 70 patients with acute and chronic viral hepatitis using specific and sensitive enzyme immunoassay and immunoradiometric assay. The results were compared with those in patients with influenza and in healthy controls. Twelve out of 28 patients with acute viral hepatitis showed positive alpha-IFN and/or gamma-IFN activities. alpha-IFN was detectable throughout the clinical course while gamma-IFN levels rose in the convalescent phase regardless of etiology. Conversely, in patients with influenza, both alpha-IFN and gamma-IFN levels of initial samples tended to be higher than those of late samples. Six out of 12 patients with chronic active type B hepatitis showed increased alpha-IFN and/or gamma-IFN values during acute deterioration with marked elevation of serum alanine aminotransferase. However, the two interferons did not always appear simultaneously, although either was detectable in both acute and chronic hepatitis. Enhanced alpha-IFN or gamma-IFN activity was not found in asymptomatic chronic hepatitis B carriers or in patients with chronic persistent hepatitis and liver cirrhosis with chronic hepatitis B virus infection, with the exception of 2 cases. Our results indicated that circulating multiple IFN species were present during the clinical course in some patients with acute and chronic viral hepatitis.

An estimated total of 811,037 years of life were lost for persons between 28 days and 64 years of age in Chile from 1981 to 1983. 63% correspond to males. Main causes of death accounting for these figures include non accidental violent death (15.6%), accidental death (13.4%), pneumonia and influenza (9.9%), tumors (7.5%) and cirrhosis of the liver (5.6%). Almost 50% of the loss occurred in the 28 day to 11 month and the 25 to 44 year age groups. Regional variation, from a minimum of 5895 years of life lost for 100,000 persons in Arica to 9,640 in Bio-Bio.

In Southeast Asia, 15 to 20 percent of the population are hepatitis B surface antigen carriers. The majority of these carriers have chronic hepatitis and would progress to cirrhosis or hepatocellular carcinoma at an annual incidence of 2 percent and 1 percent, respectively. Previous studies from Southeast Asia suggested that immunosuppressive therapy could be harmful, or at best of no value, and antiviral treatment with vidarabine, picibanil, or even interferon was also unsatisfactory. Currently, a randomized controlled trial of human lymphoblastoid interferon, with or without prednisolone pretreatment, versus placebo in patients with hepatitis B core antigen in the liver and hepatitis B e antigen in the serum is being conducted. Forty-five patients (29 receiving interferon, 16 receiving placebo) have been entered in the trial for at least two months. Actuarial analysis shows that the response to interferon therapy was better than that to placebo. Although flu-like symptoms, hair loss, and body weight loss were seen, no side effect requiring specific treatment has been encountered. These preliminary results suggest that human lymphoblastoid interferon is effective and safe in Oriental patients.

Ceftizoxime (CZX), a parenteral cephalosporin derivative belonging to the so-called third generation cephalosporin is reported to have a broad antibacterial activity, particularly against Gram-negative aerobic bacilli and some anaerobes, such as Bacteroides fragilis and a good stability to beta-lactamases. Clinical study was performed on a total of 20 cases, 9 females (1 case had urinary tract infection 3 times) and 11 males, aged from 27 to 82 years. All patients had the underlying diseases. They were bronchial asthma in 3 cases, influenza in 1, chronic pulmonary emphysema in 1, pulmonary fibrosis in 1, chronic bronchitis with strongyloidiasis in 1, lung cancer in 3, esophagus cancer in 2, stomach cancer in 1, hepatoma with urolithiasis in 1, liver cirrhosis with diabetes mellitus in 1, alcoholism with strongyloidiasis in 1, cholelithiasis in 1 and congestive heart failure in 1, respectively. Clinical diagnoses for infections were 2-acute bronchitis, 2-exacerbation of chronic bronchitis, 2-broncho-pneumonia, 2-pneumonia including one suspected case, 1-obstructive pneumonia, 2-secondary pulmonary infection, 1-pulmonary infection, 3-urinary tract infection (UTI), 1-UTI with sepsis, 1-sepsis, 1-sepsis with purulent meningitis, 1-biliary tract infection and 1-infected bronchoesophageal fistula. CZX was given by intravenous drip infusion, at a dose of 1 to 2 g, twice daily for 3 to 15 days. Because of severity in infections and underlying diseases, some cases were treated either steroid, gamma-globulin preparations or other antibiotics in combination with CZX. Twelve out of 15 cases assessed clinically responded satisfactorily to the treatment and efficacy rate was 80.0%.(ABSTRACT TRUNCATED AT 250 WORDS)

Two hundred and twenty-six patients suspected of having liver disease were examined clinically, by a liver biopsy and laboratory test, according to a prospective scheme. Blood samples obtained just before the liver biopsy were coded and subsequently examined blindly, using the complement fixation test (CFT). The antigens were influenza A and B viruses, parainfluenza 1, 2, and 3, respiratory syncytial viruses, varicella, morbilli, cytomegalo and herpes simplex viruses. The sera were also examined by the CFT against Mycoplasma pneumoniae antigen. Antibodies against rubella virus were determined in a haemolysis-in-gel test. HBsAg and HBsAb were determined by a staphylococcal radioimmunoassay, and sera from patients with chronic active hepatitis (CAH) and chronic persistent hepatitis (CPH) were also examined for antibodies against hepatitis A virus by radioimmunoassay. Highly significant antibody titres against morbilli virus were found in patients with CAH and CPH. Patients with CPH or liver cirrhosis also had significantly higher titres against rubella virus than other groups. Some patients with liver granulomas had high titres against rubella virus. Only in one patient with CAH was a positive test for HBsAg found, and in one a positive test for HBsAb. Seven patients in the CAH and CPH groups had very high titres against both rubella and morbilli viruses.

Alpha-interferon has emerged as the most effective agent for the treatment of chronic hepatitis when active replication of virus B or D is present. Exogenous administration of human alpha-interferon, now possible through modern large-scale production methods, is associated with disappearance of virus from blood. Amelioration of liver disease occurs in 35% of patients with chronic hepatitis B (e-positive) with interferon doses of 10 MU thrice weekly for 16 weeks; after therapy persistent normalization of serum aminotransferases is observed in 30%. Improvement in liver disease has only occasionally been documented for chronic hepatitis D and for chronic hepatitis B e-minus mutant. Enhanced response rates (> 50%) may possibly be obtained by prolonged intermittent interferon therapy. Combination of interferon with another "antiviral" agent (vidarabine, acyclovir, prednisone) has not increased therapeutic efficacy. Alpha-interferon induces side-effects such as fatigue, flu-like syndrome, myalgia and changes in mood. Patients with decompensated cirrhosis are particularly prone to bacterial infection and disease exacerbation and should receive lower-than-normal doses. Interferon, when applied skillfully, induces the highly beneficial transition of active viral replication into viral latency, thereby greatly reducing infectivity, symptoms and activity of the liver disease.

The high worldwide prevalence of chronic viral hepatitis, as well as its progressive course, have led to the performance of multiple clinical studies. The natural history of the disease is different depending on the infecting virus; thus, the evolution to liver cirrhosis and/or hepatocellular carcinoma for the hepatitis B, C and delta (D) viruses in chronic hepatitis is 15, 20 and 75%, respectively. Different therapeutic agents have been used in attempts to modify the natural course of these diseases, interferon-alpha (IFN alpha) having proved to be the most effective. In 30 to 50% of patients, treatment with IFN alpha has achieved inhibition of viral replication, as well as normalisation of aminotransferase levels. Moreover, in a majority of patients, histological improvement is observed, principally in piece-meal necrosis and portal inflammation. The dosage currently recommended for treatment of chronic hepatitis B is 30 to 35MU weekly for a minimum of 4 months; when there is a co-existing delta virus infection, the total dosage employed should be greater. For hepatitis C, the minimum effective dosage is 9MU weekly, and a treatment duration of 12 months is recommended. The administration of IFN alpha produces a series of dose-dependent adverse effects, which are reversible on suspension of the medication. The most frequent of these adverse reactions is the 'flu-like' syndrome, which is self-limited and generally well tolerated. Secondary haematological alterations (leucopenia and thrombocytopenia) are the most frequent cause of reduction in dosage or suspension of treatment, although the latter is not normally necessary. The proportion of patients requiring dosage modification or suspension of treatment fluctuates between 5 and 15%. Taking the evolution of chronic hepatitis into account, there can be no doubt that all patients with this disease should be offered treatment. At present, the drug of choice is IFN alpha, as it slows disease progression and it is generally well tolerated.
