AIM： Many cirrhotic patients have muscular symptoms and rhabdomyolysis. However, myopathy associated with liver cirrhosis has not been established as a disease entity. We evaluated the clinical significance of acute myopathy associated with liver cirrhosis. METHODS： We retrospectively reviewed the medical records of 5440 cirrhotic patients who had been admitted to Gyeongsang National University Hospital from August 1997 to January 2003. Among these, 99 developed acute myopathies, and they were analyzed with respect to clinical and laboratory parameters, and outcomes. RESULTS： The Child-Pugh classification at the time of myopathy onset was A in 3（3.1%） cases, B in 33（33.3%）, and C in 63 （63.6%）. Infection was identified as the most predisposing factor to myopathy. Fifty percent of 18 idiopathic cases who were tested for influenza antibody were positive. Forty-two of the 99 cases were complicated by acute renal failure, and 25 （59.5%） of these expired. Apart from 6 cases lost to follow-up, 64 of 93 recovered, giving a mortality rate of 31.2%. Mortality was higher in Child-Pugh class C than in B or A. CONCLUSION： Acute myopathy can develop as a serious complication in liver cirrhosis. Its frequency, severity and mortality depend on underlying liver function, and are higher in decompensated liver cirrhosis. Influenza should be considered as an etiologic factor in idiopathic cases. It is proposed that acute myopathy associated with liver cirrhosis be called ＇hepatic myopathy; and that careful monitoring for hepatic myopathy is necessary in the patients with advanced liver cirrhosis.

Interstitial lung disease （ILD） is a comprehensive term referring to a group of lung diseases affecting the interstitium of the lung. Idiopathic pulmonary fibrosis （IPF） is the most common idiopathic ILD, and nonspecific interstitial pneumonia （NSIP） is the second most common. As the name suggests, NSIP is diagnosed atter many other diseases are excluded. The main pathological finding in NSIP is homogeneous interstitial inflammation with or without fibrosis. NSIP can be categorized by cellular type or fibrotic type, according to the grade of inflammation and fibrosis. The cellular type has mostly inflammatory lesions with good responses to steroid, but the fibrotic type has a large proportion of fibrosis mixed with inflammatory lesions and a relatively poor response to steroid treatment So far, the exact mechanism underlying idiopathic lED has not been clarified. Determining key regulators of these ILDs will be helpful in the diagnosis and development of novel drugs for ILD.
