Patients undergoing autologous hematopoietic stem cell transplantation (auto-HSCT) for autoimmune disease may have an added propensity to develop a second autoimmune disorder, given the genetic predisposition to autoimmunity. Therefore, we undertook a retrospective analysis of all patients who have undergone auto-HSCT for an autoimmune disease in our institution to determine the occurrence of a...

Exercised-induced vasculitis (EIV) is an underreported and frequently misdiagnosed condition that occurs on the lower extremities shortly after exercise. Most reported cases have presented in healthy-appearing individuals, but some cases have been linked to other disease processes. A case report is presented of recurring EIV in a 65-year-old woman with a history of dermatitis herpetiformis; chr...

Autoimmune hepatitis is a heterogeneous liver disease of unknown etiology. It is predominant in females and characterized by elevation of transaminase, hypergammaglobulinemia and circulating autoantibodies. Interface hepatitis and plasma cell infiltration are the main findings on liver biopsy. However, deep cholestatic jaundice is rarely seen. We present here an unusual case of type 1 autoimmun...

Although genetics contributes to the development of autoimmune diseases, it is clear that "environmental" factors are also required. These factors are thought to encompass exposure to certain drugs and environmental pollutants. This paper examines the mechanisms that normally maintain immune unresponsiveness in the liver and discusses how exposure to certain xenobiotics such as trichloroethylen...

Autoimmune diseases may appear as paraneoplastic syndromes during the course of a neoplastic disease, the most common being dermatomyositis/ polymyositis. The association of systemic sclerosis and cancer is not clear. The case of a 56-year-old male with rectal cancer and systemic sclerosis where the coexistence of the two diseases was closely related, so that scleroderma was considered a parane...

The increasing demand for liver transplantation and the decline in donor organs has highlighted the need for alternative novel therapies to prevent chronic active hepatitis, which eventually leads to liver cirrhosis and liver cancer. Liver histology of chronic hepatitis is composed of both effector and regulatory lymphocytes. The human liver contains different subsets of effector lymphocytes th...

There are a growing number of cases detailing acute hepatic necrosis in patients taking black cohosh (Cimicifuga racemosa), an over-the-counter herbal supplement for management of menopausal symptoms. Our aim is to illustrate two cases of liver injury following the use of black cohosh characterized by histopathological features mimicking autoimmune hepatitis. Both patients reported black cohosh...

OBJECTIVE Autoimmune hepatitis and primary sclerosing cholangitis are chronic inflammatory disorders of unknown aetiology, frequently associated with the presence of perinuclear antineutrophil cytoplasmic antibodies (p-ANCAs) directed against an unknown antigen of myeloid cells. METHODS AND RESULTS Here, it is reported that p-ANCAs in autoimmune liver disorders react with beta-tubulin isotype...

BAFF and a proliferation-inducing ligand (APRIL), which control B cell homeostasis, are therapeutic targets in autoimmune diseases. TACI-Fc (atacicept), a soluble fusion protein containing the extracellular domain of the BAFF-APRIL receptor TACI, was applied in clinical trials. However, disease activity in multiple sclerosis unexpectedly increased, whereas in systemic lupus erythematosus, ataci...
