Abstract

Background: Endocrine disorders are among the most common complications in thalassemia patients. Although cardiac complications are the main cause of mortality, endocrinological disturbances have a significant impact on morbidity and quality of life. Methods: Sixty-eight patients (35 F, 33 M; 60 thalassemia major, 8 thalassemia intermedia) admitted to our outpatient clinic between August 2015 - December 2017 were included in the study. Patients were evaluated for short stature, hypogonadism, glycemic abnormalities, hypoparathyroidism, hypothyroidism and osteoporosis. Results: The average height of thalassemia major patients was 165.67±8.8 cm in men and 155.6±6.6 cm in women. Nine patients had short stature (4 F, 5 E), but 91.5% (54/59) of the whole group had low IGF-1 levels. There were 23 thalassemia major patients (11 F, 12 M) who had a history of hormonal induction therapy for delayed puberty. Overall, 60% (n = 36) of the patients were currently receiving hormone replacement therapy for central hypogonadism (19 F, 17 M). The median age at diagnosis of central hypogonadism was 22.5 years in men (IQR: 16.5-27.5) and 18 years in women (IQR: 16-25). There were five diabetic thalassemia major patients in study group whose median age at diagnosis was 20 (16-36). Of the 47 patients who underwent OGTT, 13 thalassemia major patients had prediabetes (27.7%). None of the thalassemia intermedia patients had glycemic abnormalities. Subclinical hypothyroidism was present in 19.7% (13/66) of the whole group, hypoparathyroidism was found in 8.5% (9/59) of thalassemia major patients, and vitamin D deficiency (25OH D < 20 ng/ml) was found in 70.8% (46/65) of all patients. Of 64 patients who underwent BMD, 25 had osteoporosis (39.1%) while 23 hadosteopenia (35.9%). The incidence of pathological fractures in thalassemia major patients was 20% (11/55). Conclusions: The incidence of endocrine disorders may increase in thalassemia patients due to prolonged duration of lifespan. Regular screening for newly emerging endocrinopathies during adulthood has great value. In our study, the most common endocrine disorders were vitamin D deficiency, hypogonadism, osteoporosis and glycemic abnormalities; respectively. Early diagnosis and treatment would prevent patients from having related morbidities and therefore increase quality of life.
