Using the clearance of microaggregated iodinated human serum albumin reticuloendothialial system (RES) phagocytic function was tested in 48 long-term renal allograft recipients and was found to be defective at the time of testing in 70%. Depression of RES phagocytosis could be related to total steroid dosage in the previous year and to the patients liability to bacterial infections. Evidence from this test does not suggest an immunosuppressive effect of cytomegalovirus. However, three patients are discussed who have developed chronic active hepatitis that is not due to type B virus.

Peripheral lymphocytes from patients with hepatitis-B surface antigen (HBsAg)-positive and -negative acute hepatitis (AH), chronic active hepatitis (CAH), chronic persistent hepatitis (CPH), and normal controls were tested for in vitro cytotoxicity and blast transformation. Cytotoxicity was measured by chrominum (21Cr) release into the medium from 51Cr-labeled Chang liver cells after incubation for 6 h with peripheral lymphocytes at a lymphocyte target cell ratio of 200:1. Concomitant 72-h incubation studies were performed to assess thymus cell-dependent (T) lymphocyte function as measured by conccanavalin A (Con A)- stimulated incorporation of tritiated thymidine (blast transformation) and by cytotoxicity. It was found that (a) lymphocytes from patients with AH are cytotoxic to Chang liver cells compared to controls (P less than 0.001); (b) lymphocytes from patients with acute and chronic hepatitis are less cytotoxic when incubated with autologous and homologous HB2Ag-positive and -negative AH, CAH, and CPH are as cytotoxic as normal controls when stimulated with a nonspecific mitogen such as Con A; and (d) lymphocytes from patients with CAH while on prednisone therapy showed marked depression of cytotoxicity when stimulated with Con A. Thus these studies show that patients with AH have circulating T lymphocytes which are capable of causing the destruction of Chang liver cells. There is no defect in T-cell function as measured by Con A-stimulated cytotoxicity. There is a serum factor (s) in patients with acute and chronic hepatitis which inhibits spontaneous and induced lymphocyte cytotoxicity and blast transformation. Finally, prednisone treatment appears to inhibit lymphocyte cytotoxicity in patients with CAH.

The fatty acid pattern of blood serum lipids was examined by gas liquid-chromatography in 30 cases with bilharzial hepatic fibrosis, 11 cases with chronic active hepatitis accompanied by jaundice, and 28 healthy individuals as a comparison group of the same socioeconomic class of patients. In addition, the fatty acid patterns of the three major serum lipid classes, namely: cholesterol ester, phospholipids and triglycerides, were also investigated in seven cases of each group by gas liquid chromatography. The most remarkable differences were: a depression of the essential fatty acid level (linoleic and arachidonic) in both groups of patients together with a concomitant elevation of oleic acid in the bilharzial group and an elevation of oleic, palmitic, palmitoleic acids in the chronic active hepatitis group. The depression of linoleic and arachidonic acids was explained by the low fat diet intake, malnutrition, and the malabsorption factors which were frequent in all the patients studied. The elevation of monoethenoid acids was attributed to the decrease in the ability of the liver to desaturate the endogenous saturated and monounsaturated acids to polyunsaturated ones.

Eleven patients in early stages of chronic active hepatitis B (CAH-B) were treated for weeks or months with a natural or recombinant human interferon alpha (Hu IFN alpha). Changes of serum levels of selected hepatitis B virus (HBV) markers were observed after Hu IFN alpha administration. Increase of HBsAg level accompanied by more or less simultaneous HBeAg level depression was the most interesting observation. These changes were well expressed in 5 reactive patients only; they usually ceased after withdrawal of IFN therapy. Reaction of the remaining 6 patients was either poor or not demonstrable. The possible mechanism for HBsAg/HBeAg serum level changes during the IFN therapy of CAH-B is discussed.

To evaluate the role of severe liver damage on natural killer cell activity, 29 patients with liver cirrhosis were examined. The natural killer cell activity was measured with a 4-hr chromium release assay, and the K562 cell line was employed as target cells. The natural killer cell activity was significantly decreased in cirrhotic patients compared with normal controls and patients with chronic active hepatitis. Cirrhotic patients with Pugh's C grade of severity of liver disease had lower natural killer cell activity. The depression of natural killer cell activity in cirrhotic patients was inversely correlated with prothrombin time ratios, and the natural killer cell activity in cirrhotic patients with hepatic encephalopathy was lower than in patients without hepatic encephalopathy. Thus, the diminished natural killer cell activity in cirrhotic patients might be related to the severity of liver damage.

Biotransformation capacity was investigated in patients with various degrees of alcoholic liver damage. Aim of the investigation was to study the impairment of biotransformating ability during progression of liver damage. Four groups of patients with various liver diseases (alcoholic fatty liver, chronic persistent hepatitis, chronic active hepatitis, alcoholic cirrhosis) and two groups as controls were studied. The investigations were carried out with exogenous test substances (antipyrine, menthol and sulphadimidine) and by determination of D-glucaric acid excretion. It has been concluded that the depression of biotransformating ability in patients with alcoholic liver diseases is progressing during development of diseases. The changes in various metabolic pathways are different, and they seem to be more marked in the first phase of biotransformation than in the second phases.

Peripheral T lymphocytes from patients with chronic active hepatitis (CAH) showed a significantly decreased suppressor cell (or increased helper cell) effect on differentiation of allogenic B cells to Ig-producing cells (Ig-PC). Spontaneous helper cell activity as measured after irradiation of T cells appeared normal, while Concanavalin A (Con A)-induced suppressor cell activity was significantly reduced. Some patients of chronic persistent hepatitis (CPH) also showed mild depression of Con A-induced suppressor cell activity. Poor suppressor cell activity in CAH was much more often seen in HBsAg negative, autoantibody positive patients than in HBsAg positive autoantibody negative ones. Autologous mixed lymphocyte reaction (AMLR) was significantly decreased in patients with CAH. Also, a serum factor(s) that decreased Con A-induced suppressor cell function of healthy subjects could be demonstrated in some patients with CAH and CPH. Our results suggest that altered immune responses observed in CAH may be due to defective suppressor cell function, partly attributable to serum factor(s).

The clinical course of 40 patients with significant quantities of mixed cryoglobulins, but without lymphoproliferative, collagen-vascular or chronic infectious diseases, is presented. These cases comprise 51.3 percent of all mixed and 31.7 percent of all types of cryoglobulins evaluated by us over the period 1960--1978. A characteristic clinical syndrome, consisting of recurrent palpable purpura (100 percent), polyarthralgias (72.5 percent) and renal disease (55 percent), was seen. Biopsy specimens of skin lesions showed cutaneous vasculitis, and half had immune reactants in vessel walls. Seventy percent of patients had evidence of hepatic dysfunction, often subclinical, and more than 60 percent of those tested had serologic evidence of prior infection with hepatitis B virus. Hepatic lesions ranged from minimal triaditis to chronic active hepatitis and/or cirrhosis. All 22 patients in whom clinical renal disease developed had significant proteinuria; 63.6 percent had diastolic hypertension, 77.3 percent edema, 45.5 percent renal failure and 22.7 percent were nephrotic. Glomerular disease associated with deposition of immunoglobulin G, immunoglobulin M and complement, often with coexistent renal arteritis, was confirmed pathologically in 15 cases. All cryoglobulins had rheumatoid factor activity and consisted of IgM and polyclonal IgG; five also contained IgA. Thirteen had a monoclonal IgM kappa component. Serum protein electrophoresis was unremarkable or showed diffuse hyperglobulinemia. Striking depression of early complement components was noted but did not correlate well with the cryoprotein concentration, renal involvement or clinical course. Follow-up for periods up to 21 years from onset of symptoms revealed that renal involvement has a deleterious effect on prognosis. Postmorten examinations of nine patients demonstrated widespread vasculitis in addition to renal involvement. Preterminal infection was found in eight.

An analysis was made of 41 cases of disseminated intravascular coagulation in dogs, with the objective of evaluating routine and nonroutine laboratory tests used in making the diagnosis. The dogs were grouped on the basis of underlying disease, which included neoplasia (39%), pancreatitis (30%), chronic active hepatitis (15%), heat stroke (12%), and sepsis (4%). Of the diagnostic tests evaluated, those for determination of activated partial thromboplastin time, antithrombin III activity, prothrombin time, and the platelet count were the most valuable. Of the clotting factors, factor V activity was decreased more frequently than the activity of factor VIII:C (factor VIII: procoagulant). The factor VIII:C activity was in conflict with prevailing dogma that reflects depression of this factor in disseminated intravascular coagulation. Factor VIII:C activity was decreased in only 29% of dogs studied. Activation of the fibrinolytic system was manifested by decreased plasminogen activity in 49% of the dogs studied. Sixty-one percent of the dogs had increased amounts of fibrin (ogen) degradation products.

To assess the efficacy of recombinant alfa 2b-interferon treatment "Heberon alfa R" in children with chronic active hepatitis (CAH) B virus, we conducted a long-term study (three years) in 22 children infected with hepatitis B virus (17 males and 5 females), age range 3 to 15 years. Diagnostic criteria included the clinical picture, laboratory tests, virus markers (HBeAg, HBsAg), laparoscopy and liver biopsy. Children under 12 years received 3 million IU of interferon per day whereas those older than 12 years received 6 million IU of interferon per day by intramuscular injection, three times per week for four months. Alanine aminotransferase (ALT) levels had been elevated for six months in all patients and hepatitis B viral infection was replicative. A variance analysis was made to evaluate ALT response to interferon administration and the Mc Nemar test was used to analyze HBeAg/anti-HBe behavior. Seventeen (77%) out of 22 patients responded to treatment (clearance of HBeAg and ALT levels returned to normal. HBeAg seroconversion (anti-HBe) occurred in 36% of patients during the first year (p < 0.01) and it increased to 50% by the third year follow-up. ALAT levels also decreased and the difference was statistically significant (p < 0.01). This occurred during and after treatment with a steady and increasing tendency to return to normal levels within the first and third year. Side effects were scarce, transient and tolerable and they only appeared during the initial phase of treatment; symptoms were mainly influenza-like and they disappeared very soon. There were no late side effects such as medullar depression, renal toxicity and glycemia alterations.(ABSTRACT TRUNCATED AT 250 WORDS)
