Bacterial Spondylitis in Dialysis Patients That Hospitalized With Diagnosis of Catheter Infection

Abstract

This research was a descriptive-analytical cross-sectional study and its target population included dialysis patients admitted to the infectious departments of Imam Reza and Sinai Hospitals in Tabriz with a diagnosis of catheter infection with spondylitis in the past 5 years and who had positive blood cultures. The sampling method was census. In the review of the files, all dialysis patients with catheter infection who had positive blood cultures were determined and associated complications were noted and patients who have mentioned the problem of spondylitis or referred to the cause of spondylitis have been identified and after excluding other causes such as tuberculosis (in biopsy), brucellosis (Write test), fungal causes (by culture and biopsy), malignancies and bone metastasis of the rest of the patients were included in the study. Results: In this study, 200 patients were examined, and the prevalence of bacterial spondylitis with the diagnosis of catheter infection was 15 cases (7.5%). Among underlying diseases and duration of dialysis, none of the variables of cancer, ESRD, diabetes, osteomyelitis and duration of dialysis were statistically significant between the two groups of dialysis patients with bacterial spondylitis and without bacterial spondylitis (P-value>0.05). Also, among the variables of surgical intervention, the only variable of dialysis catheter in the group of dialysis patients with bacterial spondylitis was significantly more than the group of dialysis patients without bacterial spondylitis (P-value=0.040). Among the associated symptoms and outcome variables, the variables of fever (P-value=0.042), vomiting (P-value=0.091), dysuria (P-value=0.010), back pain and vertebral tenderness (P-value<0.001) and site of involvement (lumbar, thoracic and cervical) (P-value<0.001) in the group of dialysis patients with bacterial spondylitis was significantly more than the group of dialysis patients without bacterial spondylitis. Among the blood factors, the variables WBC (P-value=0.039), Neutrophil (P-value<0.001), PT (P-value=0.041) and CRP (P-value=0.044) in the group of dialysis patients with bacterial spondylitis was significantly more than the group of dialysis patients without bacterial spondylitis; On the other hand, the variables of Lymphocyte (P-value=0.001) and negative blood culture (P-value<0.001) in the group of dialysis patients without bacterial spondylitis were significantly more than the group of dialysis patients with bacterial spondylitis.
