The beneficial effects of conventional long treatment on declining renal function in diabetic nephropathy (non-insulin-dependent diabetes mellitus, NIDDM) were evaluated retrospectively. One hundred NIDDM patients with overt proteinuria were followed for more than three years. Clinical data before and after various regimens of treatment were compared statistically. Treatment included a calcium antagonist (CaA), alpha-methyl dopa (AMD), an alpha-blocker (ABL), angiotensin converting enzyme inhibitor (ACEI), anti-platelet agents (APL), essential amino acids (EAA), and an oral absorbent (AST-120). Changes in renal function were analyzed by comparing the degree of slopes of regression rate of the reciprocals of serum creatinine levels (R1/Cr). Administration of ACEI and EAA resulted in R1/Cr improvement after the initiation of treatment (p less than 0.05). It appears that the administration of EAA and ACEI are beneficial with regard to protection against renal failure in NIDDM patients with diabetic nephropathy.

We retrospectively reviewed the clinical and laboratory data of 1154 patients with biopsy-proven CAH observed in 12 Italian referral liver units. The data obtained at the time of hospitalization were recorded and computerized. The data were analyzed for the presence or absence of HBsAg, sex, classes of age and three different degrees of the histological severity of CAH (mild, severe, with cirrhosis). HBsAg was present in 700 patients (61%). As compared with HBsAg negative patients HBsAg positive patients were younger, showed higher values of aminotransferases, were more frequent males and less frequently showed histological evidence of cirrhosis and associated diseases (diabetes, peptic ulcer and biliary stones). Patients younger than 15 years showed higher AST and lower gammaglobulins levels than patients in other age classes. Moreover, both in HBsAg positive and HBsAg negative CAH, patients with cirrhosis were older than patients without histological evidence of cirrhosis.

Overproportional GLDH-increase was found to be the most frequently appearing pathological enzyme pattern in canine practice. Thus it could be shown that GLDH deviates, in spite of its mitochondrial localization and greater molecular weight, more frequently and to a higher degree from its reference value than the parameters ALT, AST, AP, GGT and Bilirubin. The results of the study suggest that the liberation of the enzyme is less determined by the intensity than by the intralobular target of the liver insult. Therefore an increase in GLDH-activity should no longer be interpreted as the result of severe liver damage. On the contrary, the enzyme appeared to be the most sensitive indicator for the diagnosis of primary and secondary hepatopathies. The phenomenon of isolated GLDH-increase could be interpreted in almost every disease group as an appearance of the over-proportional increase and can therefore be understood as a serological expression of a slight, perivenous liver affection. Only with effusion patients the enzyme pattern should be regarded as an independent finding, because it has extrahepatic reasons. The induction of the enzyme in cases of diabetes mellitus is discussed.

Ninety-seven cases of pyogenic liver abscesses in a 4-yr period were studied: 27.8% (27 cases) were associated with biliary tract stone, 5.2% (five cases) were associated with biliary tract cancer, and there were two cases of diabetes (2.1%) associated with anal infection, but 63.9% (63 cases) were diagnosed as cryptogenic. Forty patients (64.5%) in the cryptogenic group had diabetes mellitus, and 23 of them (23/40, 57.5%) had gas-forming infection. All patients received parenteral antibiotics therapy, percutaneous aspiration, drainage, or operation. The overall mortality was 16.5%. Diabetes mellitus alone, without demonstrable infectious foci, was an important predisposing factor for pyogenic liver infection. Furthermore, to evaluate the clinical importance of gas-forming pyogenic liver infections, we separated these 42 diabetic patients into gas-forming and non-gas-forming groups, after sonography and CT scan. Klebsiella pneumoniae was the major pathogen in both groups. There was no significant difference in the clinical manifestations, complication, bacterial culture, or laboratory data between these two groups, except that the AST level was higher in the gas-forming group. However, the gas-forming group had higher mortality rate (30.4% vs. 5.3%). Gas-forming liver abscesses were common among the diabetics. Early and adequate drainage for pyogenic liver abscesses with parenteral antibiotics are crucial in their management.

Glurenorm, a IInd generation sulfanylurea preparation, was used for a year as a sugar-reducing drug in 20 patients with non-insulin-dependent diabetes mellitus and concomitant diseases of the liver (cirrhosis, chronic hepatitis, n = 5) and biliferous duct (cholelithiasis, a state following cholecystectomy, chronic cholecystitis, n = 15). A year follow-up has not shown deterioration of liver function as indicated by results of liver tests (AST, ALT, acid phosphatase, gamma-glutamyltranspeptidase, bilirubin, cholesterol, triglycerides). The hypoglycemic effect of the drug proved to be inferior to that of sulfanylurea derivatives, but the absence of side effects permit higher doses of glurenorm (up to 4-6 tablets daily) as against other oral sugar-reducing drugs.

The therapeutic effect of most immunosuppressive agents is unspecific and therefore often limited by an increased risk of infection by viral, bacterial or fungal organisms as well as by an increased incidence of malignant neoplasms. This short review includes the most commonly used immunosuppressants such as corticosteroids, azathioprine, methotrexate, cyclophosphamide and cyclosporine. The most common risks of long-term corticosteroid treatment are Cushing-like changes, decreased glucose tolerance and the usually benign steroid diabetes. Also clinically important is osteoporosis, since it can be prevented by physical training, calcium supplementation and treatment with vitamin D if necessary. Although there is still no proof of a significantly increased risk of peptic ulcer during steroid therapy, patients may develop gastrointestinal hemorrhage and even perforation without producing pain while being treated with corticosteroids. Mineralocorticoid effects, such as salt and water retention, are seen only with hydrocortisone and prednisone, whereas with synthetic steroids such as dexamethasone, sodium retention is absent despite their strong antiphlogistic activity. The most important side effect of the cytotoxic agents azathioprine, methotrexate and cyclophosphamide is marrow suppression. Due to the high turnover of neutrophils, patients most frequently suffer neutropenia rather than thrombocytopenia or anemia. Neutropenia, as well as impaired humoral and cellular immune mechanisms, are responsible for increased susceptibility to bacterial, viral or parasitic diseases during immunosuppressive therapy. Hepatotoxicity has been reported among patients receiving azathioprine (cholestatic hepatitis) and methotrexate (elevated AST levels and, rarely, liver fibrosis or cirrhosis). Cyclophosphamide causes hemorrhagic cystitis in a substantial proportion of patients, as well as an increased incidence of urothelial neoplasms. Both these side effects may be prevented by Mesna. The most important side effects of cyclosporine are acute and chronic nephrotoxicity usually associated with significantly elevated plasma levels of the drug. It must be borne in mind that severe nephrotoxicity may occur in patients receiving cyclosporine and ketoconazole together, since the latter may inappropriately increase the plasma cyclosporine level.

Nonalcoholic steatohepatitis (NASH) is the term used for a common form of fatty liver presenting in adults with varied clinical manifestations. The most common presentation is asymptomatic elevation of liver enzymes (AST or SGOT and ALT or SGPT), which can be discovered incidentally in the course of an annual checkup, life insurance examination, or as part of surrogate screening before blood donation. At the other end of the clinical spectrum is the patient with complications from cryptogenic cirrhosis, who also shows a lack of evidence of alcohol as an etiological factor in pathogenesis. Clinical associations of probable relevance include gender (female), obesity, diabetes, and hyperlipidemia, but many patients do not conform to any of these stereotypes (e.g., young men of normal weight with normal fasting glucose and lipid levels). Liver biopsy confirms the diagnosis of NASH, the association of steatosis with an inflammatory response being the sine qua non for the condition and "creeping fibrosis" being a variable but possibly sinister feature. Newer imaging techniques may provide convincing evidence of steatosis, but they give little insight into ongoing fibrosis, and liver biopsy therefore remains the gold standard. The mainstay of treatment remains judicious weight loss coupled with positive dietary advice, including the ingestion of adequate but not excessive vitamins. After initial encouraging data. the assessment of ursodeoxycholic acid currently being studied under randomized controlled conditions is eagerly awaited.

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.

Nonalcoholic steatohepatitis (NASH) may present with increased hepatic fibrosis progressing to end-stage liver disease. No factors that determine increasing fibrosis and histologically advanced disease have been recognized, thus, liver biopsy is recommended in all patients for diagnosis and prognosis. Our aim was to identify independent predictors of severe hepatic fibrosis in patients with NASH. One hundred and forty-four patients were studied. All patients underwent liver biopsy. Clinical and biochemical variables were examined with univariate and multivariate analysis. Thirty-seven (26%) patients had no abnormal fibrosis, 53 (37%) had mild fibrosis, 15 (10%) had moderate fibrosis, 14 (10%) had bridging fibrosis, and 25 (17%) had cirrhosis. In multivariate analysis, older age (P =. 001), obesity (P =.002), diabetes mellitus (P =.009), and aspartate transaminase/alanine transaminase (AST/ALT) ratio greater than 1 (P =.03) were significant predictors of severe liver fibrosis (bridging/cirrhosis). Body mass index (P =.003) was the only independent predictor of the degree of fat infiltration. Increased transferrin saturation correlated positively with the severity of fibrosis (P =.02) in univariate analysis, and there was a trend for more female patients among those with more advanced fibrosis (P =. 09). However, iron studies or gender were not significant when controlled for age, obesity, diabetes, and AST/ALT ratio. In conclusion, older age, obesity, and presence of diabetes mellitus help identify those NASH patients who might have severe liver fibrosis. This is the subgroup of patients with NASH who would be expected to derive the most benefit from having a liver biopsy and considering investigational therapies.

The aim of our study was to verify if the diabetic population can be considered at risk for HBV (B hepatitis virus) and/or HCV (C hepatitis virus) correlated viral hepatitis. We examined 1514 diabetic patients, 668 males and 846 females. In patients who had, on at least two occasions, pathological transaminase values (AST and/or ALT), the markers for HBV and HCV infection were determined. Of the 1514 patients studied, 295 (19.48%) had pathological values of ALT and /or AST. Among the hypertransaminase patients (295), 69 were not tested for the markers because they refused to give informed consent; of the remaining 226 patients, 54 were negative and 172 (76.6%) were positive for at least one of the hepatitis markers (HBV, HCV or both). Those who were anti-HCV positive were 115 (38.98%), of which 50 were also positive to hepatitis B (16.9%), while those positive only to the B markers were 57 (19.3%). If we compare the patients with positive markers (172) to the total number of diabetic patients studied (1514), we find that there is a hepatitis B and/or C prevalence of 11.36%, with no statistically significant difference between females (95/846, 11.23%) and males (77/668, 11.53%). The prevalence of only hepatitis C was 7.6%, while only hepatitis B was 7.1%. In conclusion, our study shows an increasing prevalence of hepatitis C and B, often associated, in type 2 diabetic patients that allows us to define them as a group at risk for viral hepatitis.
