title: [Myocardial and renal morphological changes in drug addicts with infective endocarditis].
abstract: The autopsy specimens of the myocardium and kidneys from 233 patients with infective endocarditis (142 and 91 with and without a history of drug abuse, respectively) were studied by conventional microscopy and immunohistochemistry. In the drug abusers (DA), myocytolysis was a dominant form of myocardial damage and in the non-DA that was contraction degeneration. In DA, lower cardiomyocytic cl-2 expression arouses speculations on the possible role of apoptosis in the pathogenesis of heart failure in this group of patients. Membranous glomerulopathy was a hallmark of renal pathology in DA, contrasting with the predominance of mesangial lesions in non-DA. Increased CIC deposition may be regarded as a major contributing factor.
