Evaluation of 25-Hydroxy-Vitamin D Levels in Hypothyroid Patients Receiving Levothyroxine Sodium Therapy
Abstract
Aim: It was aimed to evaluate 25-hydroxy-vitamin D (25 (OH) D)
levels in hypothyroid patients with levothyroxine sodium (LT4)
therapy and euthyroidism.
Material and Method: 116 patients with hypothyroidism with LT4
treatment and euthyroidism in the Internal Medicine Policlinic, as
control group, 110 patients with similar age and sex without hypothyroidism were enrolled to study. Patients were recorded in terms
of age, sex, LT4 drug doses and free T4, TSH, 25 (OH) D, BUN,
Creatinine, Calcium (Ca), Phosphorus (P), Albumin values. There
was a significant difference between the groups.
Results: In study, 25 (OH) D level was significantly lower in patients
with hypothyroid patients receiving LT4 therapy and euthyroidism
than in control group (p<0.001). In the patient group there was no
significant relationship between the 25 (OH) D levels and the LT4
drug doses received by the patients (r=0.060 p=0.52). There was
no relationship in the 25 (OH) D levels between the women and the
men (p=0.75).
Conclusion: It was concluded that 25 (OH) D levels may be lower
in hypothyroid patients treated with LT4 and that low vitamin D
levels may be involved in the etiology of hypothyroidism and that
active vitamin D supplementation in addition to LT4 therapy with
hypothyroidism may be beneficial.

Levotiroksin Sodyum Tedavisi Alan Hipotiroid Hastalarda 25-Hidroksi-Vitamin D Düzeylerinin Değerlendirilmesi
Abstract
Amaç: Bu çalışma ile levotiroksin sodyum (LT4) tedavisi alan ve
ötiroid seyreden hipotiroid hastalarda 25-Hidroksi-Vitamin D (25
(OH) D) düzeyinin değerlendirilmesi amaçlandı.
Materyal ve Metot: Çalışmaya İç Hastalıkları polikliniğinde LT4 tedavisi alan ve ötiroid seyreden hipotiroidili 116 hasta ile, kontrol grubu olarak benzer yaş ortalamasında ve cinsiyette hipotiroid olmayan
110 hasta alınmıştır. Hastalar yaş, cinsiyet, aldıkları LT4 ilaç dozları ilserbest T4, TSH, 25 (OH) D, BUN, Kreatinin, Kalsiyum (Ca), Fosfor
(P), Albümin değerleri açısından kaydedildi. Gruplar arasında anlamlı
fark olup olmadığı araştırıldı.
Bulgular: Çalışmada LT4 tedavisi alan ve ötiroid seyreden hipotiroid tanılı hastalarda, kontrol grubu hastalarına göre 25 (OH) D
düzeyi, anlamlı olarak düşük bulundu (p<0,001). Hasta grubunda
25 (OH) D düzeyleri ile hastaların aldıkları LT4 ilaç dozları arasında
anlamlı bir ilişki yoktu (r=0,060 p=0,52). Kadınlar ve erkekler arasında 25 (OH) D düzeyleri açısından anlamlı bir ilişki yoktu (p=0,75).
Sonuç: LT4 tedavisi alan ve ötiroid seyreden hipotiroid hastalarda,
25 (OH) D düzeyinin düşük bulunması, hipotiroidinin etiyolojisinde
düşük vitamin D düzeyinin rolünün olabileceği, ayrıca düşük vitamin D düzeyi olan hipotiroidili hastalara LT4 tedavisine ilave olarak
aktif vitamin D verilmesinin faydalı olabileceği sonucuna varıldı.
