Abstract
Objective: Blood transfusion and iron chelators are necessary for the
survival of patients with β-thalassemia but endocrinopathies due to iron overload
can decrease the life expectancy in these patients. Moreover, the injectable iron
chelators lead to discomfort and poor compliance among the patients compared
the oral one.
Material and Methods: Seventy two patients with β-thalassemia major from
April 1997 to August 2017 at the Children’s Medical Center Hospital in Tehran,
Iran, enrolled to this study. Patients were divided into two groups according to
the type of chelator. Group1 (39 patients) received oral iron chelator while the
group2 (33 patients) received the injectable once.
Result: Seventy two patients, 51% female and 49% male were evaluated.
The mean age of the patients was 20.4±5.9 years. Prevalence of IGT, DM and
clinical and subclinical hypothyroidism were 17.94%, 5.1%, 17.4%, and 25.64%
in group 1 and 18.1%, 9.02%, 24.5% and 24.3% in group 2 respectively. There
was no case of hypoparathyroidism and twenty patients had no endocrine
complications.
Conclusion: The lack of a difference in the incidence of some
endocrinopatheis between the two groups (injectable and oral iron chelator)
offered use of painless and high compliance oral iron chelator instead of
injectable once.

Introduction
β-thalassemia major is a hereditary hemoglobinopathy due to
defect in the production of β-globulin chain. Te most common
manifestations of disease are anemia and hepatospelenomegaly (due
to extramedullary hematopoiesis). Te mainstay of treatment of the
β-major thalassemia is frequent blood transfusion that leads to iron
overload in the critical organs include; liver, heart and endocrine
glands [1,2]. Iron chelators for attenuated of iron overload in body
are used in two ways: injectable (subcutaneous deferoxamine) and
recently oral once (Deferiprone; L1). Deferiprone is well inserted into
the cell and removes iron, so is more efective than defroxamine in
reducing endocrine complications and cardiac iron overload [3,4].
Endocrinopatheis is one of the most common complications due
to iron overload and approximately, 60% patients have at least one
endocrine organ involvement [5]. Tere are a few studies compare
efcacy of oral and injectable iron chelator for decrease endocrine
complications in β-thalassemia major patients. Here, we compared
some endocrinopathies include: IGT (impared glucose tolerance),
DM (diabetes mellitus), hypoparathyroidism (clinical and subclinical)
and hypothyroidism in the patients with β-thalassemia major who
received oral chelators against the injectable once.

Patients and Methods
Seventy two patients with homozygote β-thalassemia major were
included to this study. Te patients were treated at the Children’s
Medical Center Hospital, Tehran, Iran, from April 1997 to August
2017. Β-thalassemia major was diagnosed in the early of life by standard
methods of peripheral blood smear and hemoglobin electrophoresis.
Individual characteristics and type of used iron chelator were collected
in the specifc questionnaire. All of the patients were divided into two
group 1(received oral iron chelator; Deferiprone or L1) include; 39
patients (38.46% male and 61.53% female) with age average of 19.5
years and group 2 (received injectable iron chelator; deferoxamine)
include; 33 patients (60.6% male and 39.3% female) with mean age
of 21.3 years. Deferiprone therapy was started 6 to 65 months (mean
29.9 ± 11.2 months) afer receiving deferoxamine therapy from early
age. Te endocrine functions were evaluated for all the patients before
and afer of Deferiprone therapy. Fasting plasma glucose levels 110-
125 mg/dl or 140-199 mg/dl afer OGTT (oral glucose tolerance test
2 hours) was considered IGT (impaired glucose tolerance). Fasting
blood glucose levels greater than 126 mg/dL or OGTT more than 200
mg/dl or presence of the symptoms of diabetes and plasma glucose
concentrations greater than 200 mg/dL, were regarded to have
