چکیده
Primary biliary cirrhosis (PBC) is a chronic autoimmune disorder of unknown etiology. The disease affects middle-aged women and is characterized by the destruction of the intralobular bile ducts that causes consequent cholestasis. AMA is a hallmark of PBC, composed mostly of IgG and IgM class. The M2 antibody is the most specific one, with sensitivity range of 54-98% depending on type of test used. PBC is often accompanied by other autoimmune diseases, such as Sjögrens syndrome, thyroiditis, rheumatoid arthritis, dermatomyositis, polymyositis. Interstitial lung disease (ILD) has been reported in patients with primary biliary cirrhosis but its frequency and nature are poorly understood. We report pulmonary involvement in the course of PBC in 4 middle-aged women. Histopatological examination of lung specimens was available in three patients: two presented with sarcoid - like granulomas, one with lymphocytic interstitial pneumonia (LIP). In one patient the diagnosis of pulmonary fibrosis was based on clinical and radiological features. Because of abnormal pulmonary function tests (PFT) results all the patients were treated with prednisone, one, additionally with azathioprine. The treatment was successful in all of the patients.

Introdution: Primary biliary cirrhosis is a chronic cholestatic disease of the liver, characterized by the inflammation plus progressive and non-purulent destruction of the small biliary ducts, and the presence of auto antibodies against mitochondrial self-antigens. It seems that the prevalence of PBC in the western world is more than other parts of the world. This study aimed to identify all t...

A 47-year-old male was admitted with subacute onset of dry cough and fever. Chest tomography demonstrated multifocal areas of consolidation and ground glass attenuation. Cytological analysis of bronchoalveolar lavage revealed lymphocytosis and eosinophilia and anatomopathological exam of transbronchial cryobiopsy showed poorly formed non-caseous granulomas associated to interstitial lympho-plas...
متن کاملPulmonary Manifestations among Patients with Primary Biliary Cirrhosis
Primary biliary cirrhosis (PBC) is a chronic progressive cholestatic liver disease caused by diffuse inflammation, destruction and fibrosis of the intrahepatic bile ducts, ultimately leading to cirrhosis, portal hypertension and liver failure. The pathogenesis of PBC is incompletely understood, but current data suggest roles for genetic susceptibility and environmental factors. PBC is often tho...
متن کاملIncreased Risks of Spontaneous Bacterial Peritonitis and Interstitial Lung Disease in Primary Biliary Cirrhosis Patients With Concomitant Sjögren Syndrome
The incidence of Sjögren syndrome (SS) in primary biliary cirrhosis (PBC) patients is high. The influence of SS on the clinical outcomes of PBC patients, however, remains unclear. Our study retrospectively collected data on PBC-only patients and PBC patients with concomitant SS (PBC-SS) to compare the clinical differences of long-term outcomes between them.A total of 183 patients were diagnosed...
