Infective endocarditis in chronic haemodialysis: two treatment strategies
Centro de Nefrología, Hospital de Clínicas, Universidad de la República, Montevideo, Uruguay
Abstract
Background. Infective endocarditis (IE) is more frequent in patients on chronic haemodialysis (CHD) than in the general population and vascular access is the more frequent identified port of its entry. According to experimental and clinical studies the vascular access may also interfere with the treatment of IE. To improve the treatment of IE in CHD, patients were temporarily switched to peritoneal dialysis (PD) after the removal of the vascular access. In this preliminary report the outcome of IE in those CHD patients switched to PD is compared with the outcome in IE patients who remained on CHD.
Methods. All cases of IE that occurred during a 5 year period were retrospectively analysed. The Duke criteria for IE were used for diagnosis. All patients underwent transoesophageal echocardiography. All patients were treated with the same schedule of antibiotic treatment. The vascular access of a patient was removed when it was judged to be the source of infection.
Results. Twenty-one patients were studied. Twelve patients had been temporarily switched to PD after the diagnosis of IE and nine patients had remained on CHD treatment. There were not statistically significant differences between the two groups with respect to demographic data, comorbid diseases and the frequency of Staphylococcus aureus as the causative germ. In-hospital mortality was 8.3% in patients switched to PD and 55.5% in patients maintained on HD (P: 0.03).
Conclusions. The data presented here suggest that the high mortality of IE in CHD patients may also be associated with the vascular access necessary for HD. If these results are confirmed by prospective studies with higher numbers of patients, PD could turn out to have a place in the treatment of IE in CHD patients.
