1/3. pleural effusion during interferon treatment for chronic hepatitis c.A 54-year-old male patient was admitted to Osaka University Medical School Hospital for interferon treatment for chronic hepatitis c and the daily administration of recombinant interferon-alpha 2a started at the dose of 9 megaunits per day. Fourteen days later, moderate right pleural effusion was detected by abdominal magnetic resonance imaging study. He had experienced no symptom to suggest pleural effusion or any pulmonary lesions during interferon treatment. The pleural fluid was serous, showing the character of slightly bloody, turbid and positive Rivalta test, and the levels of lactic dehydrogenase and adenosine deaminase were not elevated. His serum titer of anti-nuclear antibody increased to 80 in homogenous staining, but anti-dna antibody and anti-liver kidney microsome-1 antibody remained negative. Other laboratory tests or physical findings could not satisfy the criteria of any autoimmune diseases, such as systemic lupus erythematosus. After discontinuation of interferon administration, his pleural effusion resolved gradually and disappeared completely by use of no specific drugs. This is the first case that pleural effusion developed during interferon administration without any other clinical signs indicating autoimmune diseases. The increase of serum titer of anti-nuclear antibody prompted us to elucidate that pleuritis might be induced by immunological activation of interferon.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/3. Interstitial pneumonitis during combination therapy with interferon-alpha and ribavirin in a patient with chronic hepatitis c.After nine weeks of combination therapy with recombinant interferon-alpha and ribavirin for chronic hepatitis c a 62-year old woman complained of a dry cough and exertional dyspnea. An elevated erythrocyte sedimentation rate was noticed. Prior to treatment chest x-rays and physical examination revealed no pulmonary abnormalities. Inhalative steroids did not improve the symptoms and afer 12 weeks treatment chest X-ray and computed tomography showed bilateral reticonodular lung infiltration suggesting a diagnosis of interstitial pneumonitis. cough and dyspnea resolved and abnormal lung shadows were reversible within two months following discontinuation of interferon-/ribavirin treatment. In the Japanese literature there are similar reports on pneumonitis occurring during high-dose IFN-alpha and concomitantly Chinese herbal medicine treatment. To our knowledge this is one of the first cases of interstitial pneumonitis due to combination therapy with IFN-alpha and ribavirin in chronic hepatitis c reported in the western world.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/3. hydrothorax without ascites in liver cirrhosis.pleural effusion in patients with liver cirrhosis and intractable ascites is well known, but hepatic hydrothorax in the absence of ascites is a rare complication. We present the case of a 43-year old male, with a medical history of liver cirrhosis due to hepatitis c virus, who was admitted to the Pneumology Clinic for dyspnoea, worsening of general status and chronic asthenia. The pleural effusion, revealed on physical and laboratory examinations, persisted despite the therapy with diuretics and the frequent thoracocentesis. The thoracostomy followed by pleurodesis also failed. The pecularity of this case was the presence of refractory hydrothorax in the absence of ascites.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
