The female patient initially showed the acquired type of total lipoatrophy at about 8 years of age. At 12 years of age, the onset of diabetes mellitus was speculated from advanced pyodermia and dedentition. At 29 years of age, glucosuria was found, and she developed proteinuria, ascites, and pretibial edema. The physical examination revealed: hepatosplenomegaly, complete absence of subcutanous fat, cutaneous xanthomas, and emaciated facies with pronounced zygomatic arches. Diabetic retinopathy was revealed in the ophthalmological examination, and nephropathy was evident in renal biopsy specimens. She also had peripheral diabetic neuropathy. No adipose tissue was found in the mesenterium under peritoneoscopy. The hepatic biopsy specimen revealed advanced portal liver cirrhosis. Laboratory findings included: hyperlipidemia, elevation of BMR without evidence of hyperthyroidism, impaired renal function, and undetected anti-insulin antibodies and anti-insulin antibodies. Endocrinological examinations revealed normal value, except for an impaired hGH response in the arginine test. C-peptide immunoreactivity was high. Her condition was fairly well controlled by 140 units of insulin injection daily.

This is a case report of a 35-year-old female who showed a relatively short clinical course of severe liver cirrhosis and proteinuria. On light microscopical studies of autopsy material, besides active postnecrotic type liver cirrhosis, typical membranous glomerulonephritis was found. Immunofluorescent study disclosed not only clustered HBsAg (hepatitis type B surface antigen) in occasional hepatic cells but also beaded granular type deposition of HBsAg, IgG, IgM, IgA and complement C3 along renal glomerular basement membrane (GBM). Electron microscopical study disclosed multiple particulated material in occasional inclusion bodies of hepatic cells and in subepithelial and subendothelial dense deposits along the GBM. Enzymatic immunoelectron microscopical study confirmed these particles especially along the GBM being HBsAg themselves. It was concluded that HBsAg-Ab (antibody) complex was the pathogenetic factor responsible for the glomerular change of this particular case. Although HBsAg and Ab were examined to be negative in serum throughout the patient's clinical course, the possibility of the presence of circulating HBsAg-Ab complex in serum was discussed.

The long-term clinical course of patients with primary Type II essential mixed cryoglobulinaemia is unclear as many reports fail to separate this group from patients with Type III disease. We have reviewed 13 patients with Type II essential mixed cryoglobulinaemia who presented to the Hammersmith Hospital between 1976 and 1990. All patients had a cryoglobulin level greater than 0.1 mg/ml (range 0.27-6.50 mg/ml), and characterization of the cryoglobulin in all cases revealed the presence of a monoclonal IgM kappa component with rheumatoid factor activity together with polyclonal IgG. All patients had evidence of activation of the classical pathway of complement with greatly reduced levels of C4, while C3 levels were moderately reduced in three patients. All patients had skin disease and joint symptoms were reported by nine patients, with erosive arthritis in one. Eight patients had peripheral sensorimotor neuropathy. Renal disease was observed in 10 patients, manifesting as raised creatinine level, proteinuria or haematuria. Renal tissue was examined in eight patients: in six the appearances were those of a mesangiocapillary glomerulonephritis Type I while in the other two patients there was a mesangioproliferative glomerulonephritis, in one diffuse and in the other focal and segmental. Glomerular capillary 'hyaline thrombi' were found in six biopsies, extracapillary proliferation was found in three and evidence of vasculitis was found in all eight. Liver biopsy showed macronodular cirrhosis in one patient, while a second with recurrent episodes of jaundice showed only chronic inflammatory changes. No patient was positive for hepatitis B surface antigen; however one patient had low titre anti-hepatitis B surface antibody. Normochromic normocytic anaemia was present in nine patients. Bone marrow examination was carried out in 13 patients at presentation to our unit: 10 showed no evidence of a lymphoproliferative disorder, while three suggested the presence of a non-Hodgkin's lymphoma (some years after original presentation in all three). Unusual clinical features included one patient with retinal vasculitis and one patient with severe pulmonary haemorrhage.

A 38-year-old man with liver failure due to Laennec's cirrhosis developed nephrotic range proteinuria and hematuria. Renal biopsy showed membranoproliferative glomerulonephritis with 2+ staining for IgA and complement consistent with cirrhotic glomerulonephritis. After orthotopic liver transplantation, proteinuria and hematuria rapidly resolved. This case indicates that glomerulonephritis associated with cirrhosis may be successfully treated with hepatic transplantation. Whether the improvement in glomerular abnormalities resulted from immunosuppression therapy or from restoration of normal hepatic function is unknown.

Plasma concentrations of the recently isolated potent vasoconstrictory peptide endothelin were measured in 382 patients. The investigations were performed by means of a sensitive radioimmunoassay specific for Endothelin-1, 2. The results from 110 healthy volunteers displayed a normal range of 44.67 +/- 3.51 pg/ml. Significantly raised levels were found in 33 patients with chronic end-stage renal failure both before and after hemodialysis. In contrast, 35 patients with compensated renal insufficiency did not differ from the normals. Sixty-five patients after kidney transplantation revealed significantly elevated levels, as did 27 patients with acute myocardial infarction, 8 after coronary bypass surgery, and 5 with liver cirrhosis. The mean values of 27 patients with untreated hypertension, 22 with secondary hypertension, of various causes and 16 with coronary artery disease were comparable to the normal population. The values were significantly decreased in 9 pregnant women with hypertension and proteinuria. A marked decline was found in 5 patients with systemic lupus erythematodes, while 20 patients with rheumatoid arthritis demonstrated only a slight decrease. The pathophysiological role of endothelin as a local or circulating hormone in regulating systemic blood pressure or release of other hormones remains to be determined.

The frequency of mesangial IgA deposition was examined in 250 consecutive autopsy cases without known renal disease. Diffuse granular mesangial deposits of IgA were detected in 12 of 250 cases (4.8%). In six patients IgA deposits were associated with liver cirrhosis. Six patients (2.4%) suffered from various other conditions including endocarditis, bronchial asthma, cardiovascular disease, and neoplasia. Two of these patients had completely negative urine analysis on repeated investigations, whereas three patients exhibited microscopic haematuria and/or mild proteinuria. IgA1 was the major constituent in all specimens. C3c deposits in glomeruli were detected in one kidney. Our findings indicate that clinically overt renal disease is present in only a limited proportion of individuals with mesangial IgA deposits. Apparently, it represents the tip of an iceberg.

Renal vein thrombosis in early infancy is a complication of dehydration and prolonged hypotension. The onset is usually acute and the most common clinical signs are uni- or bilateral frank masses, hematuria, proteinuria and thrombocytopenia. In most cases, with conservative management, the late outcome is favorable. In the adult, renal vein thrombosis is often a silent complication of the nephrotic syndrome, the hypercoagulability of which may be an important factor in the pathogenesis of the thrombosis. Clinically, the presentation of a sudden complete occlusion is that of severe abdominal and lumbar pain with hematuria and loss of function of the kidney that suffers hemorrhagic infarction. Physical examination often reveals an enlarged kidney. With gradual occlusion, renal function is preserved. The initial diagnostic approach is with ultrasound studies and computed tomography; definitive diagnosis is established by renal venography or by selective renal arteriography. In general, a conservative approach including the use of anticoagulant treatment is preferred to surgical intervention. Priapism is a persistent painful penile erection due to ischemic or non-ischemic causes; therapeutic intracavernosal injection of papaverine is becoming the most common cause. In early and mild stages, aspiration of blood from the corpora cavernosa supplemented with intracavernosal irrigation with alpha-stimulating agents is the procedure of first choice; in late and severe ischemia, a shunt procedure may become necessary. Hepatic vein thrombosis occurs in association with a number of conditions considered predisposing factors including the use of oral contraceptives. The clinical picture may be that of an acute illness with abdominal pain, hepatomegaly, ascites and hepatic failure as well as early death. More often, the onset is insidious with slowly developing ascites and wasting. For the diagnosis, hepatic scintigraphy may be helpful but, at present, ultrasonography, computed tomography and magnetic resonance scanning are procedures of choice. There is, as yet, no adequate treatment. A fatal outcome may be prevented by surgical decompression of the congested liver and, in recent years, liver transplantation has been employed. Portal vein thrombosis, in children, is usually considered a complication of umbilical sepsis or a result of a congenital abnormality of the portal vein. In adults, the most frequent causes are hepatic cirrhosis and neoplasia. Clinically, there may be a sudden appearance of ascites with resolution in a symptom-free interval until the onset of other features of portal hypertension occur. Currently, ultrasound real-time imaging supplemented with Doppler capability, computed tomography and magnetic resonance scanning provide the necessary diagnostic information. Variceal hemorrhage is often the first major complication requiring treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

It is known that chronic alcoholics and type II diabetics show hyperlipidemia, characterized by hypertriglyceridemia and in a minor degree by hypercholesterolemia. The mechanisms underlying the effect of ethanol and carbohydrates on plasma lipids seem to be different; therefore in diabetic subjects chronic alcohol consumption could produce a more severe hyperlipidemia and so accelerate atherosclerotic events. In order to verify it we have measured plasma cholesterol, HDL-cholesterol, and triglycerides and investigated the presence of micro- and macroangiopathy in two groups of non-insulin-dependent diabetics, differing each other for daily alcohol intake (18 chronic male alcoholics and 30 male subjects consuming respectively more than 150 g and less than 50 g of alcohol daily). In alcoholics, no clinical features, laboratory and echographic findings of cirrhosis and pancreatic disease were present. In order to avoid a possible interference of other factors on the metabolism of plasma lipids, in our study patients were selected with the following criteria: 1) only male subjects; 2) age 40-60 years; 3) nonsmokers; 4) moderate coffee drinkers; 5) average physical activity; 6) with BMI less than 28; 7) in good diabetic control (HbA1c less than 6%, n.v. 4.4%-5.6%); 8) normal kidney function (plasma creatinine less than 1.3 mg%) and 24 hr proteinuria absent;) 9) in treatment with diet alone or diet plus low doses of sulphonylureas or biguanides. The data were analyzed by Student's "t" and chi-squared tests. No significant differences could be detected (alcoholics/occasional drinkers, means +/- 1 SD) either in the plasma levels of cholesterol (181.7 +2- 39.3/198.2 +/- 32.5), HDL-cholesterol (43.4 +/- 12.7/38.5 +/- 11.9), and triglycerides (105.5 +/- 56.4/159.7 +/- 114.8) and in the frequency of micro (22.2%/16.6%) and macroangiopathy (16.6%/26.6%) between the two studied groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Twelve HBsAg-negative patients with histologically documented cirrhosis of the liver of either alcoholic (8 of 12) or cryptogenic (4 of 12) origin underwent renal biopsy to investigate proteinuria, hematuria and/or renal failure. Immunofluorescence was positive for IgA in 2 patients with mesangiocapillary glomerulonephritis (MCGN) and could not be performed in 2 additional patients with the same diagnosis. However, in the remaining 8 patients, immunofluorescence was negative for IgA and frequently positive for C3, IgG, IgM and/or fibrinogen. These 8 patients without IgA were classified as follows: MCGN with subendothelial electron-dense deposits (2 cases), IgM-IgG cryoglobulinemia with diffuse endocapillary glomerulonephritis (1 case), membranous nephropathy (1 case), diffuse endocapillary proliferative glomerulonephritis (1 case), vasculitis with focal segmental necrotizing glomerulitis and crescentic glomerulonephritis (2 cases). These results show that cirrhosis of the liver can be associated with a wide variety of glomerular disorders. Contrary to previous belief, IgA is absent in two thirds of patients with cirrhosis and glomerulopathy. Therefore, the pathogenetic importance of IgA in the development of glomerular disease in such patients is doubtful.

Glomerulonephritis is a little known manifestation of liver cirrhosis. Since the introduction of sophisticated immunologic staining methods, glomerular morphologic abnormalities have been noted in more than 50% of patients with cirrhosis at both necropsy and biopsy. The distinctive pathologic findings consist of glomerular mesangial IgA deposits usually accompanied by complement deposition. Increased serum IgA levels are found in over 90% of cirrhotic patients with glomerular IgA deposition. Cirrhotic glomerulonephritis is usually a clinically silent disease, however, the diagnosis can be suspected by finding proteinuria or abnormalities of the urine sediment. The pathogenesis may relate to defective hepatic processing and/or portacaval shunting of circulating immune complexes.
