Methods The clinical features of six such patients admitted to Peking Union Medical College Hospital during the year 1990 to 2009 were analyzed. All of them were diagnosed based on Chinese Children Diagnostic Criteria for Infective Endocarditis. Results The average age of the six patients was 52.3±19.3 years old. Four were males. Vascular accesses at the onset of infective endocarditis were as follows： permanent catheters in three, temporary catheters in two, and arteriovenous fistula in one. Three were fbund with mitral valve involvement, two with aor tic valve involvement, and one with both. Five vegetations were found by transthoracic echocardiography, and one by transesophageal echocardiography. Four had positive blood culture results. The catheters were all removed. Four of the patients were improved by antibiotics treatment, in which two were still on hemodialy sis in the following 14-24 months and the other two were lost to follow-up. One patient received surgery, but died of heart failure alter further hemodialysis for three months. One was well on maintenance hemodi alvsis for three months after surgery. Conclusions Infective endocarditis should be suspected when hemodialysis patients suffer from long-term fever, for which prompt blood culture and transthoracic echocardiography confirmation could be performed. Transesophageal echocardiography could be considered even when transthoracic echocardiography produces negative findings. With catheters removed, lull course of appropriate sensitive antibiotics and surgery if indicated could improve the outcome of chronic hemodialysis patients complicated by infective cndocarditis.展开更多

However, it us- ually occurs late in the course of the diseaseand is clinically silent. Clinically overt renal disease including acute kidney injury （AKI） as its primary manifestation is rarely reported, moreover, Fanconi syndrome （FS） is extremely rare as the main manifestation in NHL. In this report, we presented a case of NHL primarily presenting with FS and AKI due to diffuse interstitial infiltration of NHL cells and emphasized the important role of renal biopsy, especially renal immunohistochemical analysis in the diagnosis of renal diffuse lymphoma.展开更多
