Abstract

Objective: A subset of typical Hemolytic-uremic syndrome (HUS) patients requires initiation of renal replacement therapy (RRT) despite aggressive medical intervention. This study aims to evaluate the clinical and laboratory findings of patients diagnosed with typical HUS and efficacy and safety of peritoneal dialysis (PD) and hemodialysis (HD) were compared in managing these cases.

Material and Methods: Patients having a diagnosis of typical HUS were retrospectively determined, and assessment the effects of RRT modalities on renal survival.

Results: The present study included 49 children with typical HUS, and the mean age was 2.99 ± 1.88 years. Neurological involvement was detected in 15 (30.6%) patients. The neutrophil/lymphocyte ratio (NLR) was significantly higher in the neurological involvement group [odds ratio (OR) 15.42, 95% CI (3.39-70.1), p = 0.005]. In total, 43 (87.7%) patients received RRT and the median time from the first recorded symptom to RRT was six days (range 3-11). While throughout RRT, 10.2% of patients required mechanical ventilation. In this study, 26 (53.1%) patients were managed with PD, and 17 (34.6%) patients were managed with HD. During follow-up, 10.2% of all patients progressed to chronic kidney disease (CKD), proteinuria was detected in 6.1% and hypertension in 4.08%. The risk of CKD was significantly lower in the 3-month period in PD patients than in HD patients (odds ratio (OR) 7.69, 95% CI (0.77-76.07), p = 0.04).


Conclusion: We concluded that PD might be as effective and safer as HD concerning kidney recovery. Clinical features and inflammatory markers can predict neurological involvement in typical HUS cases.
