We report a case of IDDM which occurred during interferon therapy for chronic hepatitis. A 31-year-old man intermittently received 2.5 x 10(8) units of alpha-IFN and 1 x 10(8) units of beta-IFN for treatment of chronic viral hepatitis type B. Four years after the beginning of IFN therapy, he acutely developed moderate hyperglycemia and severe ketonuria with positive islet cell antibody, and then 28 units/day of insulin injection was started. After the start of insulin therapy, there was a remission period for about 3 years but insulin-dependency recurred thereafter. The clinical course of this case indicates that IFN therapy precedes IDDM. During and after IFN therapy we should consider the possibility of occurrence of IDDM as well as other autoimmune diseases and observe the clinical course carefully.

The autopsy report of Ludwig van Beethoven written by Dr Johann Wagner in 1827 reveals that he had renal calculi that had not been diagnosed during his lifetime, together with perirenal fibrosis. The most comprehensive interpretation of this autopsy finding is that the regular calcareous deposits in every one of his renal calices represented calcified necrotic papillae. Severe urinary obstruction or diabetes as possible causes of papillary necrosis were not present. Analgesic abuse because of headaches, back pain, and attacks of rheumatism or gout may be presumed on the basis of Beethoven's uncontrolled way of taking medication. Salicin, a commonly used analgesic substance of that time (dried and powdered willow bark), is able to cause papillary necrosis. Perirenal fibrosis may be due to chronic infection or drug intake. Beethoven's other well-known diseases are deafness caused by otosclerosis of the inner ear, relapsing attacks of diarrhea as the symptoms of irritable bowel syndrome, and liver cirrhosis following viral hepatitis and chronic alcohol consumption. Liver cirrhosis also may cause papillary necrosis. In Beethoven's case, renal papillary necrosis was most probably the consequence of analgesic abuse together with decompensated liver cirrhosis. The autopsy report of Beethoven is the first case of papillary necrosis recorded in the literature.

Development of type 1 insulin-dependent diabetes mellitus has been recently reported in patients who underwent interferon-alpha (IFN-alpha) therapy because of chronic viral hepatitis. Furthermore IFN-alpha seems to be involved in the immunological events that lead to beta-cell destruction and development of type 1 diabetes. To evaluate whether IFN-alpha treatment could elicit an autoimmune response against beta-cell antigens, we determined the occurrence of islet cell antibodies and insulin autoantibodies in the sera of 60 patients with HCV- or HBV-related chronic hepatitis who had been treated with IFN-alpha for 6 or 12 months. The presence of antibodies against thyroglobulin, thyroid microsomal antigen, gastric parietal cells, and non-organ-specific antigens was also investigated. Insulin autoantibody positivity was observed in 2/60 (3.3%), 8/60 (13.3%), and 4/30 (13.3%) patients, before IFN-alpha treatment, and after 6 months and 12 months of therapy, respectively. None of the studied patients developed islet cell antibodies or type 1 diabetes. Before IFN-alpha therapy four patients showed thyroid autoantibodies and four others developed antibodies against thyroglobulin and/or thyroid microsomal antigen during the treatment. Coexistence of insulin autoantibodies and thyroid autoantibodies was observed in only two patients. Our results showed that IFN-alpha therapy in patients with chronic viral hepatitis is capable of inducing development of autoantibodies against insulin. This event seems to be not related to other autoimmune disorders.

HHC is the most common inherited metabolic disease among the white population worldwide, with a gene frequency of about 10% and a frequency of homozygosity of about 1 of 250. Many patients harbor a common haplotype of informative markers on chromosome 6p2l.23, suggesting a strong founder effect exerted by a common Celtic ancestor. With the advent of screening tests (serum Tf saturation, fe), many subjects with HHC are being identified before development of cirrhosis or diabetes mellitus, and early detection is important because prompt and vigorous iron reduction prevents development of such complications and assures normal life expectancy. The HIC can be estimated as accurately by specialized magnetic resonance imaging or susceptometric measurements as by chemical measurements on liver biopsy specimens. However, biopsy specimens retain value for showing fibrosis/cirrhosis and dysplastic hepatocytes, both of which increase risks of HCC development. There is growing evidence that iron in the liver plays an important role in non-HHC diseases, such as alcoholic liver disease, chronic viral hepatitis, and porphyria cutanea tarda. The complicated, manifold roles of iron in pathogenesis of the latter disorder include enhancement of production and irreversible oxidation of uroporphyrinogen, as well as formation of an inhibitor targeted specifically at hepatic uroporphyrinogen decarboxylase. The nature of the gene and gene product that are abnormal in HHC remain elusive, despite the intense efforts of several investigative groups. The search has been hampered by a dearth of informative markers in HHC patients in the relevant region of chromosome 6p. Note added in proof: The cloning of a candidate gene, the mutation of which may perhaps cause HLA-linked hemochromatosis, has just been reported (Feder et al: A novel MHC class I-like gene is mutated in patients with hereditary haemochromatosis. Nature (Genetics) 1996;399-408). These workers identified a 250-kb region move than three megabases telomeric of the MHC that was identical in 85% of chromosomes of HHC patients. Within this region, they identified a gene related to the MHC class I family, termed HLA-H, containing two missense alterations one of which is predicted to inactivate this class of proteins. 83% of 178 patients were homozygous for this mutation (Cys 282Tyr). This variant was also found on 3.2% of control chromosomes, as would be expected for such a common disorder. Functional studies are awaited with great interest.

In China, health care delivery follows a three-tiered structure set up in the 1950s for rural and urban areas. In 1990, China set baseline criteria for primary health care in rural areas which is largely funded by a reestablished rural cooperative medical care financing system. Financing reform efforts in urban areas are using a model through which contributions are collected from salaries and from local governments and other public organizations. The overall incidence of infectious diseases is more than 500/100,000 people, but associated mortality has declined. Diseases covered by the Expanded Programme of Immunology have been controlled, but China is at high risk for viral hepatitis (epidemics of hepatitis A infections occurred in 1988), and incidence of tuberculosis has increased. In addition, the HIV/AIDS epidemic is spreading rapidly with an estimated 50,000-100,000 infected. Parasitic diseases are also widespread, and causes of death seen in developed countries (hypertension, stroke, coronary health disease, cancer, and diabetes) are increasing. With 510 million people living in iodine-deficient areas, iodine deficiency diseases have disabled an estimated 8 million people. China has promised to eradicate iodine-deficiency by the year 2000. The disabling Kaschin-Beck disease is also endemic in China. Occupational diseases threaten nearly 20 million Chinese people, and the prevalence of smoking and alcohol abuse is increasing, especially among young people. By the year 2000, 10% of the population will be older than 60, and 30% of this group will have health problems requiring care. The health care system is, thus, undergoing rapid change to meet its new challenges.

Long-term mortality and morbidity was evaluated in 267 patients with a minimum follow-up of 10 yr and the physical status, graft function and quality of life in 15 patients with a functioning graft surviving for over 20 yr were reviewed. Actual patient and graft survival rates were 80.2% and 51.1% at 10 yr (n = 267) and 56.4% and 32.7% at 20 yr (n = 55), respectively. Although the rate of graft failure due to rejection was 4 times higher than that of patient death within 10 yr, it decreased to the level of patient death in the second decade. Dominant causes of death in patients with graft surviving for over 10 yr were hepatic failure due to viral hepatitis and malignancies. In 15 patients with graft currently surviving beyond 20 yr, while all patients have excellent graft function, malignancy occurred in 5, viral hepatitis in 3, aseptic necrosis in 3, and diabetes mellitus in one patient. No patient has suffered cardiovascular complications. Despite a high rate of morbidity, they show a satisfying status of rehabilitation (full time working 11/ 15, 73.3%). In order to attain more improved QOL in patients with long-term surviving renal transplant, close follow-up aiming at diminution of complications is required throughout the period after transplantation.

Follow-up features of acute viral hepatitis were evaluated of 210 hospitalized adult patients. HA, HB, HC, and NON A-C H were diagnosed in 68 patients, 84 patients, 22 patients, and 36 patients, respectively. Post-hepatitis syndrome was shown in about 20.6%, 19%, 45.5%, and 25% of patients with HA, HB, HC, and NON A-C H, respectively. At three months, the recovery was shown in about 61.7%, 69%, 13.6%, and 63.9% of patients with HA, HB, HC, and NON A-C H, respectively. Factors of sex, age, and severity of acute phase had no effect on the protracted rate in all types, except in HB. After six months, the disease remained active in 1.5%, 6%, 69%, 8.3% of patients with HA, HB, HC, NON A-C H, respectively. Factors of sex, age, severity of acute phase had no effect on the chronicity rate in different types, except HB. It was more significantly more frequent in males, elderly persons, and mild acute phase in chronic HB cases. Diabetes mellitus was also significantly more frequent in chronic HB cases. Flat pattern of ALT elevation was significantly more frequent in chronic HB and NON A-C H cases.

The occurrence of hepatocellular carcinoma (HCC) in renal transplant recipients has typically been associated with hepatitis B or C infection. We encountered two cases of HCC in renal transplant recipients with negative hepatitis B and C markers and no underlying liver pathology, in whom immunosuppression therapy consisted of prednisone and azathioprine (AZA). Patient no. 1 is a 66-year-old man with diabetes who underwent cadaveric renal transplantation 13 years before presentation. An ultrasound obtained for evaluation of a prolonged prothrombin time and decreased serum albumin level showed a suspicious nodular lesion in the left lobe of the liver. A computed tomographic (CT) scan confirmed a 4- x 5- x 5-cm mass that, on biopsy, was determined to be well-differentiated HCC. There was no evidence of metastasis, and the results of random biopsies of the surrounding parenchyma were normal. The patient underwent a left lateral segmentectomy, did well, and an initial alpha-fetoprotein (AFP) level of 85995 ng/mL decreased to 9 ng/mL. Approximately 20 months postoperatively, however, a surveillance CT scan showed three hypervascular lesions in the right lobe of the liver and the AFP level increased to 28,370 ng/mL. Subsequent percutaneous alcohol injections yielded good results, and the patient is alive and well 13 months later. Patient no. 2 is a 57-year-old man who underwent cadaveric renal transplantation 24 years earlier. A CT scan of the abdomen obtained for evaluation of lower abdominal pain showed a 4- x 4- x 6.5-cm mass in the right lobe of the liver that, on biopsy, was found to be poorly differentiated HCC. Multiple biopsies of adjacent liver parenchyma showed no evidence of cirrhosis, AFP level was normal, and imaging studies showed no evidence of tumor spread. The patient underwent a right hepatic lobectomy and is doing well without evidence of recurrence 27 months postoperatively. Our two patients had no evidence of viral hepatitis, cirrhosis, or metabolic liver disease, yet both developed HCC. The use of AZA may have had a role in the development of HCC. In renal transplant recipients on long-term immunosuppression therapy, particularly AZA, it is prudent to maintain a high index of suspicion for HCC when liver enzyme level or function abnormalities are encountered.

The determination of aminotranferases levels is very useful in the diagnosis of hepatopathies. In recent years, an elevated serum ALT level in blood donors has been associated with an increased risk of post-transfusion hepatitis (PTH). The purpose of the study was to research the factors associated with elevated ALT levels in a cohort of voluntary blood donors and to evaluate the relationship between increased ALT levels and the development of hepatitis C (HCV) infection. 166 volunteer blood donors with elevated ALT at the time of their first donation were studied. All of the donors were questioned about previous hepatopathies, exposure to hepatitis, exposure to chemicals, use of medication or drugs, sexual behaviour, contact with blood or secretions and their intake of alcohol. Every three months, the serum levels of AST, ALT, alkaline phosphatase, gamma glutamyl transpeptidase, cholesterol, triglyceride and glycemia are assessed over a two year follow-up. The serum thyroid hormone levels as well as the presence of auto-antibodies were also measured. Abdominal ultrasound was performed in all patients with persistently elevated ALT or AST levels. A needle biopsy of liver was performed in 9 donors without definite diagnostic after medical investigation. The presence of anti-HCV antibodies in 116 donors were assayed again the first clinical evaluation. At the end of follow-up period (2 years later) 71 donors were tested again for the presence of anti-HCV antibodies. None of donors resulted positive for hepatitis B or hepatitis C markers during the follow-up. Of the 116 donors, 101 (87%) had persistently elevated ALT serum levels during the follow-up. Obesity and alcoholism were the principal conditions related to elevated ALT serum levels in 91/101 (90.1%) donors. Hypertriglyceridemia, hypercholesterolemia, hypothyroidism and diabetes mellitus also were associated with increased ALT levels. Only 1/101 (0.9%) had mild chronic active non A-G viral hepatitis and 3/101 (2.9%) had liver biopsy with non-specific reactive hepatitis. The determination of ALT levels was not useful to detect donors infected with HCV at donation in Brazil, including the initial seronegative anti-HCV phase.

While patients with liver disease are known to have a higher prevalence of glucose intolerance, preliminary studies suggest that hepatitis C virus (HCV) infection may be an additional risk factor for the development of diabetes mellitus. To further study the correlation of HCV infection and diabetes, we performed a retrospective analysis of 1,117 patients with chronic viral hepatitis and analyzed whether age, sex, race, hepatitis B virus (HBV) infection, HCV infection, and cirrhosis were independently associated with diabetes. In addition, a case-control study was conducted to determine the seroprevalence of HCV infection in a cohort of 594 diabetics and 377 clinic patients assessed for thyroid disease. In the former study after the exclusion of patients with conditions predisposing to hyperglycemia, diabetes was observed in 21% of HCV-infected patients compared with 12% of HBV-infected subjects (P =.0004). Multivariate analysis revealed that HCV infection (P =.02) and age (P =.01) were independent predictors of diabetes. In the diabetes cohort, 4.2% of patients were found to be infected with HCV compared with 1.6% of control patients (P =.02). HCV genotype 2a was observed in 29% of HCV-RNA-positive diabetic patients versus 3% of local HCV-infected controls (P <.005). In conclusion, the data suggest a relatively strong association between HCV infection and diabetes, because diabetics have an increased frequency of HCV infection, particularly with genotype 2a. Furthermore, it is possible that HCV infection may serve as an additional risk factor for the development of diabetes, beyond that attributable to chronic liver disease alone.
