BACKGROUND Autologous hematopoietic stem cell transplantation has been used since 1996 for the treatment of severe autoimmune diseases refractory to approved therapies. We evaluated the long-term outcomes of these transplants and aimed to identify potential prognostic factors. DESIGN AND METHODS In this observational study we analyzed all first autologous hematopoietic stem cell transplants f...

Studies in both humans and in animal models of specific disorders suggest that polymorphisms of multiple genes are involved in conferring either a predisposition to or protection from autoimmune diseases. Genes encoding polymorphic proteins that regulate immune responses or the rates and extent of metabolism of certain chemical structures have been the focus of much of the research regarding ge...

Although autoimmune diseases are relatively common, mechanisms that lead to their development remain largely unknown. Nuclear factor-kappaB (NF-kappaB), as a key transcription factor involved in the regulation of immune responses and apoptosis, appears to be a good candidate for studies on the pathogenesis of autoimmunity. This review presents how perturbations of the NF-kappaB signaling pathwa...

Epstein-Barr virus (EBV) can cause frequently asymptomatic (or anicteric) and self-limited hepatitis, while occasionally may result in considerable cholestatic hepatitis. Herein, we describe the case of a previously healthy toddler (26 month old girl) with prolonged cholestasis, elevated serum transaminases, EBV serology compatible with recent EBV infection and positive anti liver kidney micros...

BACKGROUND/AIMS Patients with primary Sjögren's syndrome may present liver involvement. Our goals were to establish the prevalence of abnormal hepatic biochemistries and clinical liver disease in patients with primary Sjögren's syndrome and correlate their presence with other clinical and laboratory features. METHODS Ninety-five patients with diagnosis of primary Sjögren's syndrome were studi...

INTRODUCTION Autoimmune hepatitis is an inflammatory disease with multifactorial ethiopatogenesis, characterized by lympho-monocytic infiltration of liver, presence of serum autoantibodies (ANA, SMA, LKM-1) and high levels of immunoglobulins. Overlap syndromes are defined as the association of autoimmune hepatitis with cholestatic diseases such as primary biliary cirrhosis and primary sclerosin...

Although autoimmune diseases are relatively common, mechanisms that lead to their development remain largely unknown. Nuclear factor-κB (NF-κB), as a key transcription factor involved in the regulation of immune responses and apoptosis, appears to be a good candidate for studies on the pathogenesis of autoimmunity. This review presents how perturbations of the NF-κB signaling pathway may contri...

Autoimmune diseases are a cluster of disorders characterized by a failure of the immune tolerance and a hyperactivation of the immune system that leads to a chronic inflammation state and the damage of several organs. The medications currently used to treat these diseases usually consist of immunosuppressive drugs that have significant systemic toxic effects and are associated with an increased...

Psoriasis is a chronic inflammatory disease of the skin affecting approximately 2% of the world's population. Systemic treatments, including methotrexate and cyclosporin, are associated with potential hepatotoxicity, due to either direct liver damage or immunosuppression or both immunomediated and a direct liver injury; therefore, treatment of patients with psoriasis poses a therapeutic challen...
