Objectives: This study was undertaken to assess cardiopulmonary functions in thalassemia major patients and its correlation to serum ferritin.
Methods: A hospital based observational study was conducted over a period of 11 months, between November 2015 and September 2016. 47 thalassemia major patients were included along with 20 age and sex matched controls were taken as controls.
Results: Mean age in our study population was 9.44 ± 2.030 years. The mean Sr. ferritin level was 3217+1351.853 ng/dl. 18 (38%) patients had low FEV1 and FVC; suggesting restrictive pattern along with small airway obstruction suggested by reduced FEF25% to 75%. We observed that as the serum ferritin level increased, mean value of FEV1, FVC, FEV1/FVC, FEF (25% to 75%) decreased and it was statistically significant in cases with ferritin >3000 ng/ml (p value<0.05). In echocardiography interventricular septal thickness and posterior wall diameter were significantly increased in thalassemia patients as compared to controls. The mean value of EF was lower among cases than in controls and this decrease in EF was statistically significant (p<0.05) but there was no systolic dysfunction.16 patients out of 23 (69%) had dilated cardiomypathy in group where sr ferritin was >3000 ng/dl and 5 patients out of 17 (31%) had dilated cardiomypathy in ferritin levels of 2000 to 3000 ng/dl. So the cardiovascular complications were found to be higher in the high-ferritin group (serum ferritin>3000 ng/dl) than in low-ferritin group (serum ferritin 1000-2000). In our study among 47 Thalassemic patients, 15 (40%) were found to have both cardiac pathology as well as pulmonary dysfunction. This finding was statistically significant.
Conclusion: At the end of our study on thalassemic patients, we concluded that all the PFT parameters were decreased with increasing Sr. ferritin level. Most of the echocardiographic parameters were found to be significantly deranged with reference to increase in Sr. ferritin levels. Nearly half of the patients were found to have both pulmonary and cardiac involvement.
