Is a low serum iron level a predictor of poor outcome in hemodialysis patients?
Low baseline serum iron indicators are associated with increased mortality and hospitalization in MHD patients independent of hemoglobin level, EPO and iron doses, indicators of nutrition and inflammation, and comorbid conditions. Clinical trials to examine the role of iron administration in improving morbidity and mortality by increasing serum iron levels in MHD patients are required.
'Atypical' bacteria, especially C. pneumoniae, are a common cause of community-acquired pneumonia in adults in South Africa. This is the first demonstration of an aetiological role of C. pneumoniae in this country. We confirmed the finding of other studies that there are no clinical, radiographic or laboratory features characteristic of 'atypical' bacterial infection in hospitalised patients. This has major implications for therapy, as these organisms respond to erythromycin and tetracyclines, but not to beta-lactam antibiotics.
