BackgroundPain is one of the most common complaints in clinical practice because it is a symptom for a myriad of physical and mental problems. The high prevalence of pain in the chronic kidney disease (CKD) population is particularly concerning because pain has been shown to adversely affect quality of life. The aim of this study was to evaluate the prevalence and possible causes of chronic pain in patients with end stage renal disease on long-term hemodialysis (HD).MethodsWe prospectively enrolled 100 patients who were undergoing maintenance HD for at least 6months or more. Pain was evaluated using the Brief Pain Inventory (BPI). Data collected on each participant included age, gender, body mass index (BMI), time on dialysis and biochemical findings.ResultsThe average age was 42.06years ranged from 22 to 58years; the average duration on dialysis was 4.97years. 52 patients were males and 48 were females. Although 52% of patients experienced chronic pain, only 25% described the pain as severe, 28% described pain as moderate while 52% of patients described as mild. Musculoskeletal pain was the most frequent form of chronic pain reported by patients who were on HD (54%). Malnutrition and high CRP were highly statistically associated with chronic pain (p<0.001). High statistical significant correlation was found between lower calcium, lower 25(OH) D3 levels, higher parathyroid hormone (PTH) levels and experienced chronic pain (p<0.001).ConclusionChronic pain is highly experienced in long-term hemodialysis patients. Malnutrition, high CRP and disturbed bone mineral metabolism are highly correlated with the incident of this pain.
