Visceral leishmaniasis (VL) is a life-threatening infection caused by Leishmania species. In addition to typical clinical findings as fever, hepatosplenomegaly, and cachexia, VL is associated with autoimmune phenomena. To date, VL mimicking or exacerbating various autoimmune diseases have been described, including systemic lupus erythematosus (SLE), rheumatoid arthritis, and autoimmune hepatiti...

Although hepatomegaly is reported to occur occasionally in patients with mixed connective tissue disease (MCTD) or Sjögren's syndrome (SS), autoimmune liver diseases such as primary biliary cirrhosis, sclerosing cholangitis, and autoimmune hepatitis in association with MCTD or SS have rarely been described. We report a case of severe cholestatic autoimmune hepatitis presenting with acute liver ...

In both autoimmune liver disease and chronic viral hepatitis, the injury results from an immune-mediated cytotoxic T cell response to liver cells. As such, it is not surprising that CD4(+) regulatory T cells, a key regulatory population of T cells able to curb immune responses, could be involved in both autoimmune hepatitis and chronic viral hepatitis. The liver can induce the conversion of naï...

INTRODUCTION Q fever is a zoonotic infection that may cause severe hepatitis. Q-fever hepatitis has not yet been associated with autoimmune hepatitis and/or primary biliary cirrhosis. CASE PRESENTATION We describe a 39-year-old man of Sri Lankan origin with chronic Q-fever hepatitis who developed autoantibodies compatible with autoimmune hepatitis/primary biliary cirrhosis overlap syndrome. U...

Dementia is defined as significant acquired cognitive impairment in one or more cognitive domains that represents a significant decline from previous baseline and interferes with independence in daily activities. Autoimmune dementia is a term that has been used to describe a steroid-responsive autoimmune disorder characterized by a rapidly progressive dementia with a fluctuating course. Even co...

BACKGROUND There are few reports about work-related factors associated with Sjögren's syndrome. We report a case of overlap syndrome with Sjögren's syndrome and systemic sclerosis. CASE PRESENTATION A 54-year-old man was admitted due to dyspnea on exertion. The results of physical examination and laboratory findings were compatible with Sjögren's syndrome with systemic sclerosis. The patient ...

There is growing interest in the contribution of vitamin D deficiency to autoimmunity. Several studies have shown an association between low levels of vitamin D and autoimmune disorders, including multiple sclerosis, rheumatoid arthritis, type 1 diabetes, autoimmune thyroid diseases, celiac disease, and systemic lupus erythematosus (SLE). Vitamin D receptor ligands can mediate immunosuppressive...
