[Hepatitis and pancreatitis due to indalpine].

The authors report two cases of hepatitis and a case of pancreatitis associated with indalpine. In one case of hepatitis, onset was acute and the clinical presentation was suggestive of cholecystitis; in the other case, hepatitis was discovered by biological tests. In the two cases, hepatitis was mainly cytolytic. Outcome was favorable upon interruption of drug administration. Onset of pancreatitis was inconspicuous, with progressively increasing pain. The pancreatic lesions were diffuse and massive. After interruption of administration, outcome was eventually favorable. Elevated amylasemia was also noted in the two cases of hepatitis. It is suggested that transaminase and amylase activities should be monitored during indalpine therapy.

[Urinary lithiasis secondary to intestinal diseases].

Urinary stones are much more common in subjects with intestinal diseases than in the general population. The chemical composition of the stones depends on the type of intestinal disease. In diarrhoeas with loss of water and electrolytes (inflammatory colitis and, chiefly, ileostomy), the urine is acid and concentrated and the stones are composed of uric acid. Extensive lesions of the ileum or wide resections of the small bowel increase the intestinal absorption of oxalates and expose the patients to oxalate stones. Treatment, which must be preventive, is based upon a knowledge of the pathophysiology of urolithiasis.

[Ascites inaugurating systemic mastocytosis (author's transl)].

The authors report a case of urticaria pigmentosa with systemic mastocytosis and review the literature on this occasion. The onset of the disease was marked by the development of ascites. Ascites is rarely mentioned in this affection and remains, as with other manifestations of systemic mastocytosis, without any explanation. The diagnosis was established first on the diffuse mastocyte-infiltration especially in the bone-marrow and second, on the hypersecretion of hormonal factors especially histamine by mastocytes. The symptomatic treatment of this affection is based on histamine inhibitors and disodium cromoglycate seems to be an efficient drug. With the possible development of acute leukemia, the eventual association with a carcinoma and the frequency of serious digestive bleeding, the prognosis may be very poor.

[Hepatic allograft rejection. Diagnostic and therapeutic aspects].

Rejection is still a major problem in liver transplantation: 50-70% of patients present at least one acute episode, while 5-15% develop chronic rejection. Acute rejection is suggested by clinical signs and abnormal laboratory test results, but only histological signs on biopsy specimens are adequately specific. The three most frequent elementary lesions are a portal infiltrate, bile duct alterations and endothelial inflammation. Several systems have been forwarded to classify the degree of rejection. Chronic rejection is characterized by a progressive reduction in the number of interlobular bile ducts. It does not respond to available immunosuppressive drugs and thus requires retransplantation. Prophylactic immunosuppression is usually based on the triple-drug combination cyclosporine/azathioprine/corticosteroids. The orthoclone OKT3 and FK506 have recently been proposed for prophylactic use in this setting. Treatment of liver graft recipients with cyclosporine carries a number of specific disadvantages, particularly with regard to gastrointestinal interactions (delayed intestinal absorption in patients with cholestasis, bile derivation, diarrhea or receiving cholestyramine; possibility of a sharp increase in blood cyclosporine levels when the Kehr drain is clamped), and drug interactions (cyclosporine metabolization of CP450-IIIA accounts for most such interactions). The results of radioimmunoassay and TDx must be interpreted with care, and HPLC remains the reference technique in borderline cases. Cyclosporine is hepatotoxic in about 20% of cases, generally giving rise to cholestasis. This toxicity is dose-dependent and therefore diminishes when the dosage is reduced. Most groups initially treat rejection with corticosteroids. The response to treatment is generally evaluated in terms of liver function tests.(ABSTRACT TRUNCATED AT 250 WORDS)

Latent hepatitis B virus (HBV) infection in systemic necrotizing vasculitis.

We have investigated hepatitis B virus (HBV) infection in systemic necrotizing vasculitis (SNV). Our approach included the detection of the viral surface antigen (HBsAg) with a radioimmunoassay employing monoclonal anti-HBs (m-RIA); in addition, HBV DNA was looked for in serum and peripheral mononuclear blood cells. Among 28 subjects with SNV, 12 were found to be positive for HBsAg with the conventional test (p-RIA) and 7 additional subjects had anti-HBc and/or anti-HBs. From the 16 HBsAg negative individuals, 9 had HBsAg epitopes identified in serum with the m-RIA test and 1 had a low amount of circulating viral DNA. In contrast, only 1 among 6 subjects with other systemic vasculitis showed a positive test for m-RIA and HBV DNA assays; this individual had acquired HIV infection through transfusions which were also probably the source of his HBV infection. HBV DNA sequences were identified in peripheral mononuclear blood cells of 9 from the 37 tested, including 2 individuals who were HBsAg positive only with m-RIA. Therefore, our study indicates a much higher rate of HBV infection in patients with polyarteritis nodosa than previously suspected.

[Hepatic function and significance of the increase in serum concentrations of IgA in alcoholic cirrhosis].

Elevated serum gammaglobulin concentrations are frequently observed in patients with liver cirrhosis. Predominant elevation of the IgA is generally considered as suggestive of an alcoholic aetiology. The aim of this study was to define the factors that determine the serum concentration of IgA in alcoholic cirrhosis. Twenty-seven patients with alcoholic cirrhosis were studied. Serum concentrations of IgG, IgA and IgM were measured by immunonephelometry. Hepatocellular function was assessed by the Child-Turcotte score, the prothrombin time and the intrinsic clearance of indocyanine green. The importance of intra-hepatic shunts was estimated according to the intact hepatocyte theory, and the degree of hepatic necrosis by serum levels of transaminases. It was noted that: 1) the IgA concentration correlated significantly with the Child-Turcotte score and with the decrease of the prothrombin time, intrinsic clearance and the functional fraction of hepatic blood flow; 2) there was no such correlation between the serum concentration of IgA and the total hepatic blood flow or transaminase levels; 3) there was no correlation between serum concentration of IgG or IgM and the factors studied. These results suggest that in alcoholic cirrhosis, increase in serum IgA, reflects the degree of impairment of hepatic function and intrahepatic shunting.
