Abstract
As the life expectancy in thalassemia is improving, pain is being recognized as an emerging problem. To document the pain prevalence and severity in patients with transfusion-dependent thalassemia all transfusion-dependent thalassemia patients >10 years of age (n = 165) attending the Thalassemia Day Care Center were assessed for pain prevalence, severity, and its effect on various life activities using the Brief Pain Inventory. Their medical records were reviewed for the presence of various co-morbidities. Pain was reported by 62.4% of participants with 35.2% and 59.4% of participants, reporting pain in the past 1 and 4 weeks respectively. A significantly higher pain prevalence was reported in females (p = .037), patients residing in urban areas (p = .038), and employed participants (p = .038). The commonest sites of pain were the lower back and calves. General activity (p = .02) and enjoyment of life (p = .02) were significantly affected due to pain in patients between 21 and 30 years of age. Female participants reported interference of pain with mood (p = .03). A significant correlation of pain prevalence was found with higher average serum ferritin (p = .015), moderate to severe liver iron concentration (p = .04), and lower levels of 25 hydroxyvitamin D levels (p = .03). Pain is an emerging cause of morbidity in thalassemia. The study found a significant association of pain with modifiable factors such as serum ferritin, LIC, and 25 (OH) vitamin D levels.
