Investigation of The Frequency of Thyroid Antibodies and Insulin Resistance in Early Stage Chronic Lymphocytic Leukemia

Abstract

Objectives: Chronic lymphocytic leukemia is the most common type of leukemia seen in adults worldwide. Hashimoto’s thyroiditis is the most common form of autoimmune thyroid disease. Usually, there are high levels of thyroglobulin antibodies or thyroid peroxidase antibodies. Metabolic syndrome is also very common in the world and has become a public health problem threatening the world. Immune dysregulation in metabolic syndrome, chronic lymphocytic leukemia, and autoimmune thyroid diseases unites these diseases on a common denominator. Based on this common mechanism, we aimed to investigate the frequency of insulin resistance and thyroid autoantibodies in patients with early-stage chronic lymphocytic leukemia. Materials and Methods: Sixty-five early-stage chronic lymphocytic leukemia patients and 68 healthy controls were included in the study. Thyroid stimulating hormone, thyroglobulin antibodies, thyroid peroxidase antibodies, fasting blood glucose and fasting insulin levels were measured in the patients and control groups. Statistical evaluation was performed using the Statistical Package for Social Sciences (SPSS) for Windows 20 (IBM SPSS Inc., Chicago, IL) program. The normal distribution of the data was evaluated with the Kolmogorov-Smirnov test. Normally distributed numerical variables were shown as mean ± standard deviation, while numerical variables not showing normal distribution were shown as median (minimum,maximum). P<0.05 (*) value was considered significant in statistical analysis. Results: Demographic and laboratory findings did not differ significantly between patients with chronic lymphocytic leukemia and those without thyroid dysfunction. The ratio of insulin resistance, thyroid dysfunction and thyroid antibodies in chronic lymphocytic leukemia and control groups did not differ significantly (p>0.05). Conclusion:It was observed that the frequency of insulin resistance and thyroid antibodies in early-stage chronic lymphocytic leukemia was not different from healthy controls Key Words: Chronic Lymphocytic Leukemia, Insulin Resistance, Thyroid Antibodies, Metabolic Syndrome

Erken Evre Kronik Lenfositik Lösemide Tiroid Antikorları ve İnsülin Direnci Sıklığının Araştırılması

Abstract

Amaç: Kronik lenfositik lösemi dünyada erişkinlerde görülen en yaygın lösemi tipidir. Hashimoto tiroiditi, otoimmün tiroid hastalığının en yaygın şeklidir. Genellikle yüksek seviyelerde tiroglobulin antikorları veya tiroid peroksidaz antikorları bulunur. Metabolik sendrom da dünyada çok yaygın görülmektedir ve dünyayı tehdit eden bir halk sağlığı sorunu haline gelmiştir. Metabolik sendrom, kronik lenfositik lösemi ve otoimmün tiroid hastalıklarındaki immün disregülasyon bu hastalıkları ortak paydada birleştirmektedir. Bu ortak mekanizmaya dayanarak çalışmamızda erken evre kronik lenfositik lösemili hastalarda insülin direnci ve tiroid otoantikorlarının sıklığını araştırmayı amaçladık. Gereç ve Yöntem: Çalışmaya 65 erken evre kronik lenfositik lösemi hastası, 68 sağlıklı kontrol grubu dahil edildi. Hastalarda ve kontrol grubunda tiroid stimülan hormon, tiroglobulin antikorları, tiroid peroksidaz antikorları, açlık kan şekeri, açlık insülin düzeyleri ölçüldü. İstatistiksel değerlendirme Statistical Package for Social Sciences (SPSS) for Windows 20 (IBM SPSS Inc., Chicago, IL) programı kullanılarak yapıldı. Verilerin normal dağılımı Kolmogorov-Smirnov testi ile değerlendirildi. Normal dağılım gösteren sayısal değişkenler ortalama ± standart sapma olarak, normal dağılım göstermeyen sayısal değişkenler ortanca (minimum, maksimum) olarak gösterildi. İstatistiksel analizlerde p<0,05 (*) değeri anlamlı olarak kabul edildi. Bulgular: Kronik lenfositik lösemi hastalarında tiroid disfonksiyonu olan ve olmayan hastalarda demografik ve laboratuvar bulguları anlamlı farklılık göstermedi. Kronik lenfositik lösemili hastalarda ve kontrol grubunda insülin direnci, tiroid disfonksiyonu ve tiroid antikorlarının oranı anlamlı farklılık göstermedi (p>0,05). Sonuç: Erken evre kronik lenfositik lösemide insülin direnci ve tiroid antikorları sıklığının sağlıklı kontrollerden farklı olmadığı görüldü. Anahtar Kelimeler: Kronik Lenfositik Lösemi, İnsülin Direnci, Tiroid Antikorları, Metabolik Sendrom
