Introduction: Depending on developments in dialysis techniques and new treatment strategies for comorbid diseases, life expectancy has increased. As a result, dialysis related long term complications could be seen more frequently. We investigated and compared long term complications of the Haemodialysis (HD) and Peritoneal Dialysis (PD) in patients with history if either mode at least 10years.
Materials and Methods: A 13HD & 16PD patients were included to the study. Basic demographic parameters and prevalence of cardiovascular diseases (CVD), uraemic peripheral neuropathy (PNP), parathyroid adenoma, parathyroidectomy and acquired cystic disease (ACD) were assessed.
Results: HD patients were older than PD patients (p=0.035) and duration of dialysis was longer in HD patients (p=0.001). CVD was present in 18 patients (9 HD, 9 PD). There was no difference in presence of CVD between HD and PD patients (p=0.455). Valvular diseases (n=15), diastolic dysfunction (n=8), left ventricular hypertrophy (n=5), ischemic heart disease (n=3) and congestive heart failure (n=1) were investigated. Uraemic peripheral neuropathy was observed in 14 of the patients (8 HD, 6 PD patients). Eight patients had mixed type sensory motor neuropathy and 3 patients had mixed type sensorial neuropathy, 2 patients had demyelinating PNP, 1 patient had axonal PNP and 3 of them had CTS related to peripheral neuropathy. Parathyroid adenoma was detected in 4 patients (2 HD, 2 PD) and 3 patients (1 HD, 2 PD) had history of parathyroidectomy. Serum phosphate and iPTH levels were higher in HD patients (p=0.003, p=0.04, respectively). ACD was detected in 14 patients (7 HD, 7 PD). There was no difference between PD and HD patients (p=0.75).
Conclusion: HD patients were older than PD patients and had longer duration of dialysis. The prevalence of long term complications was similar in HD and PD modalities. CVD especially valvular diseases were common complication in both modalities.
