Tissue transglutaminase 2 enzyme plays a diverse role in intracellular and extracellular functioning. Aberrant expression of anti-TG2 antibody has recently been proposed for extraintestinal identification of celiac disease (CeD), but its utility is questionable. To examine whether anti-TG2 immunohistochemical (IHC) staining can be of diagnostic value in identifying extraintestinal involvement in CeD, tissue blocks of patients with IgA nephropathies (IgAN), minimal change disease, membranous glomerulonephritis, membrano-proliferative glomerulonephritis, normal kidney, intestinal biopsies from CeD, tropical sprue, nonspecific duodenitis, and inflammatory bowel disease; liver biopsies from patients with chronic hepatitis B and C, acute liver failure (ALF), and CeD-associated liver diseases were retrieved and subjected to IHC staining for anti-tissue transglutaminase 2 enzyme...

Extrahepatic manifestations of hepatitis C virus infection (HCV) are very common. The most common of these is mixed cryoglobulinaemia. Anti-HCV antibodies and viral ribonucleic acid, HCV RNA, can be found in the cryoprecipitates, together with the rheumatoid factor. Cryoglobulins consist of a complex of immunoglobulins that in vitro precipitate upon the cooling bellow the human body temperature. Vasculitis is caused by the deposition of such immune complexes in the small blood vessels. A link with the HCV infection is considered to be established with membranoproliferative glomerulonephritis, leukocytoclastic vasculitis, lymphoproliferative disorders (in particular B cell lymphoma), Sjögren and sicca syndrome, lichen planus, porfyria cutanea tarda and diabetes mellitus...

Hepatitis C virus (HCV) infection is associated with tremendous morbidity and mortality due to liver complications. HCV infection is also associated with many extrahepatic manifestations including cardiovascular diseases, glucose metabolism impairment, cryoglobulinemia vasculitis, B cell non-Hodgkin lymphoma and chronic kidney disease (CKD). Many studies have shown a strong association between HCV and CKD, by reporting (i) an increased prevalence of HCV infection in patients on haemodialysis, (ii) an increased incidence of CKD and proteinuria in HCV-infected patients, and (iii) the development of membranoproliferative glomerulonephritis secondary to HCV-induced cryoglobulinemia vasculitis...

Chronic hepatitis C infection may be associated with several features of autoimmunity (i. e., detection of different kinds of autoantibodies in the serum). Hepatitis C is also associated with different autoimmune diseases, such as autoimmune thyroiditis, lichen ruber planus, and membranous glomerulonephritis being the most relevant. There are very few cases of a coincidence of chronic hepatitis C with an autoimmune hepatitis, that is usually diagnosed by detection of specific autoantibodies and typical histological features...

Chronic viral hepatitis B and C may associate different extrahepatic manifestations and renal disease is the most frequent. Kidney damage is represented in most cases by glomerulopathies, which include membranous nephropathy, membranoproliferative glomerulonephritis (MPGN), IgA nephropathy, focal and segmental glomerulosclerosis and diabetic nephropathy. We conducted a retrospective study on 639 patients diagnosed with chronic viral hepatitis B and C and different renal diseases. Complete evaluation of liver and renal status was performed and, in selected cases, renal biopsy...

The study aimed to estimate the incidence of HCV seroconversion in hemodialysis patients in the Brazilian Unified National Health System (SUS). This was a prospective, non-concurrent study using patients' data identified by deterministic and probabilistic record linkage in the SUS information system. The study included 47,079 patients started on hemodialysis between January 1, 2000, and December 31, 2003, followed until seroconversion or conclusion of the study in 2004. Three percent of hemodialysis patients HCV-seroconverted (1...

BACKGROUND: Crescentic glomeruli are the hallmark finding in rapidly progressive glomerulonephritis (RPGN) and are characterized by disruption and proliferation of the glomerular capsule and an influx of cells into Bowman's space. Pauci-immune-type RPGN is identified by a lack of immunoglobulins and immune complexes in the glomerular basement membrane. METHODS: Complete necropsy and histology were performed on the affected chimpanzee. Electron microscopy was performed on kidney sections...

A 95-year-old woman was admitted to our hospital for evaluation of bilateral lower-limb edema persisting for 3 months. Serum creatinine was 1.55 mg/dl, and urinary protein excretion was 9.1 g/day. Renal biopsy revealed stage 1 membranous glomerulonephritis (MGN) with immunoglobulin G4-dominant staining. This patient did not have any underlying disease such as infection with hepatitis B or C virus or malignancy, and anti-phospholipase A2 receptor (PLA2R) antibody was detected in the serum. Accordingly, idiopathic MGN was diagnosed...

BACKGROUND: The incidence of post-infectious glomerulonephritis (PIGN) in developed countries has decreased over the last 50 years. Here we identified the trends of the incidence of PIGN in Japan during the past four decades. METHODS: We explored the frequency, clinicopathological findings, and prognosis of PIGN based on 6,369 cases from the Renal Biopsy Database of our institute in the Kanto region of Japan, diagnosed histologically from 1976 to 2009. RESULTS: The numbers of PIGN cases were 131 (2...

A 63-year-old patient is evaluated for an unclear weight loss with general malaise and fatigue for several months. Serological examination reveales the first diagnosis of a hepatitis-C-virus-genotype-1b-infection with an initial viral load of 980 000 IU / ml. The duration of the infection is suggested to be more than 6 months. Because of the initially elevated anti-nuclear-antibodies (ANA) the diagnosis of an autoimmune hepatitis needs to be excluded. All other liver related autoantibodies and the immunoglobulins (Ig) IgG, IgA and IgM are normal...

BACKGROUND: In a prospective, single-center open study, we evaluated the very long-term effects of rituximab (RTX) administered to patients with severe mixed cryoglobulinemia (MC). METHODS: RTX was administered to 31 patients with MC (type II in 29 cases and type III in 2) with diffuse membranoproliferative glomerulonephritis (16 cases), peripheral neuropathy (26) and large skin ulcers (7). All but 4 patients had serum anti-hepatitis C virus antibodies. RTX was administered at a dose of 375 mg/m2, according to a '4 + 2' protocol (days 1, 8, 15 and 22 plus 1 dose 1 and 2 months later)...

Hepatitis C virus (HCV) infection is a major problem worldwide. HCV is not limited to liver disease but is frequently complicated by immune-mediated extrahepatic manifestations such as glomerulonephritis or vasculitis. A fatal complication of HCV-associated vascular disease is thrombosis. Polyriboinosinic:polyribocytidylic acid (poly (I:C)), a synthetic analog of viral RNA, induces a Toll-like receptor 3 (TLR3)-dependent arteriolar thrombosis without significant thrombus formation in venules in vivo. These procoagulant effects are caused by increased endothelial synthesis of tissue factor and PAI-1 without platelet activation...

Outbreaks of infectious canine hepatitis are described in red foxes ( ITALIC! Vulpes vulpes) at two wildlife rescue centres in the UK. Disease occurred in two-month-old to four-month-old juvenile foxes, which were held in small enclosures in groups of three to eight animals. The foxes died or were euthanased after a short clinical course, sometimes including neurological signs and jaundice, with a high case fatality rate. Four red foxes submitted for postmortem examination had enlarged, congested livers, with rounded borders and mild accentuation of the lobular pattern...

The landscape of treatment for HCV infection has evolved substantially with the advent of highly effective direct-acting antiviral agents (DAA). The Korean Association for the Study of the Liver updated guideline for managemnt of hepatitis C in accordance with the introduction of DAA into practice in late 2015. Due to high effectiveness and few side effects of DAA, indications for treatment has been widened to include patients who had been contraindicated for the combination treatment of peginterferon-α and ribavirin, i...

Cryoglobulinemic vasculitis (CV) is a small-to-medium-vessel vasculitis that appears in 10-15 % of patients chronically infected with hepatitis C virus (HCV). The classic symptom triad of CV, purpura/asthenia/arthralgia, is accompanied by clinical features that include glomerulonephritis, neuropathy, interstitial pneumonitis, and cardiomyopathy, ranging in their severity from mild to life threatening. The risk of developing non-Hodgkin lymphoma is also higher. The cumulative 10-year survival rate of CV patients is significantly lower than in the age- and sex-matched general population, with death typically caused by nephropathy, malignancies, liver involvement, and severe infections...

BACKGROUND: Antibody-mediated rejection is a leading cause for renal transplant loss. Rodent models are useful to dissect pathomechanisms and to develop treatment strategies. Although used for decades as a model, glomerular histopathological findings of Fischer-344 kidneys transplanted into Lewis rats have never been comprehensively described. METHODS: Kidneys from Fischer-344 rats were transplanted into Lewis rats as life-sustaining allografts without immunosuppression...
