SUMMARY OBJECTIVE: Polycystic ovary syndrome is the most common endocrinopathy among women of reproductive age. Polycystic ovary syndrome is a metabolic disorder associated with insulin resistance and subclinical inflammation. Dermcidin, an antimicrobial peptide, involves in insulin resistance and inflammatory processes. Dermcidin suppresses the secretion of insulin production from the liver/pancreas and also increases insulin resistance. We aimed to discover whether dermcidin levels were altered in polycystic ovary syndrome women compared to controls and determine the link of dermcidin with hormonal-metabolic parameters in polycystic ovary syndrome women. METHODS: The current research was designed as a case-control study and Rotterdam 2003 criteria were used for diagnosing polycystic ovary syndrome. A total of 75 subjects with polycystic ovary syndrome and 75 age- and body mass index-matched subjects as controls were enrolled in the study. The insulin resistance state was determined using a homeostatic model assessment of insulin resistance and quantitative insulin sensitivity check index. High-sensitivity C-reactive protein levels were assessed to define inflammation. RESULTS: Circulating dermcidin levels were measured by enzyme-linked immunosorbent assay. Dermcidin levels were significantly increased in polycystic ovary syndrome subjects compared to controls (172.53±42.41 ng/mL vs. 108.44±31.69 ng/mL, p<0.001). Homeostatic model assessment of insulin resistance and high-sensitivity C-reactive protein levels were markedly increased, whereas quantitative insulin sensitivity check index levels were notably decreased in women with polycystic ovary syndrome compared to controls. Linear regression analysis revealed that dermcidin exhibited an independent link with homeostatic model assessment of insulin resistance and high-sensitivity C-reactive protein, whereas dermcidin displayed an inversely independent link with quantitative insulin sensitivity check index. CONCLUSION: Increased dermcidin levels were associated with insulin resistance and inflammation in polycystic ovary syndrome women, suggesting that dermcidin may play a role in the pathophysiology of polycystic ovary syndrome.

RESUMO ANTECEDENTES O objetivo deste estudo foi investigar o efeito do tratamento com propiltiouracil nas moléculas de adesão em pacientes com hipertireoidismo subclínico. MÉTODOS Neste estudo, 168 pacientes diagnosticados com hipertireoidismo subclínico foram tratados com propiltiouracil por um ano. Os níveis de moléculas de adesão, especificamente sICAM-1, sVCAM-1 e sE-Selectina, antes e após o tratamento foram medidos e comparados. Esses resultados foram comparados com os níveis de 148 indivíduos saudáveis no grupo de controle que receberam um placebo. RESULTADOS Os níveis de sICAM-1 foram significativamente maiores em pacientes com hipertireoidismo subclínico do que nos controles saudáveis (*pa=0,000). Os níveis de sICAM-1 diminuíram significativamente após o tratamento (**pb=0,000). Apesar dessa diminuição em pacientes com hipertireoidismo subclínico, ela não diminuiu para o nível do grupo controle. O sVCAM-1 não se alterou antes e após o tratamento com propiltiouracil. O nível de sE-Selectina foi semelhante ao do grupo de controle pré-tratamento, mas não apresentou significância estatística, embora tenha aumentado após o tratamento (** pb = 0,004). CONCLUSÃO O nível de sICAM foi significativamente superior aos valores pré-tratamento e diminuiu após o tratamento com propilciliouracil. No entanto, mais estudos são necessários para reduzir o risco de aterosclerose e câncer em pacientes com hipertireoidismo subclínico.

SUMMARY OBJECTIVE This study aimed to investigate the effect of propylthiouracil treatment on adhesion molecules in patients with subclinical hyperthyroidism. METHODS In this study, a total of 168 patients diagnosed with subclinical hyperthyroidism were treated with propylthiouracil for one year. The levels of adhesion molecules, consisting of sICAM-1, sVCAM-1, and sE-Selectin, before and after the treatment were measured and compared. These results were compared with the levels of 148 healthy controls who received a placebo. RESULTS sICAM-1 levels were significantly higher in subclinical hyperthyroidism patients than in healthy controls (*pa=0.000). sICAM-1 levels were significantly decreased after the treatment (**pb=0.000). Despite this decrease in patients with subclinical hyperthyroidism, it did not decrease to the level of the control group. sVCAM-1 did not change before and after propylthiouracil treatment. The level of sE-selectin was similar to that of the pretreatment control group, but it did not have statistical significance, although it increased after the treatment (**pb=0.004). CONCLUSION The sICAM level was significantly higher than the pretreatment values and decreased after the propylthiouracil treatment. However, further studies are needed to reduce the risk of atherosclerosis and cancer in patients with subclinical hyperthyroidism.

RESUMO OBJETIVO Investigar os níveis séricos de anexina V e antianexina V e sua relação com os parâmetros metabólicos em pacientes diabéticos tipo 2 recém-diagnosticados. MÉTODOS Foram incluídos no estudo 143 pacientes e 133 controles com diabetes tipo 2 recém-diagnosticado. O índice de massa corporal (IMC), PCR-as, Homa-IR, espessura íntima média carotídea e níveis séricos de anexina V e antianexina V foram investigados. RESULTADOS O Homa-IR, a PCR-s do soro e a espessura média da carótida foram estatisticamente significantes. A análise de correlação de Pearson revelou uma relação positiva estatisticamente significante entre a espessura média da carótida e anexina V (r=0,29; p=0,006 *). Foi também detectada uma relação positiva estatisticamente significativa entre o nível de anexina V e o nível sérico de PCR-as (r=0,29, p=0,006*). CONCLUSÃO Também foi observada uma relação positiva entre a espessura média da carótida e anexina V no final da nossa investigação. A esse respeito, também pensamos que os níveis séricos de anexina V podem ser aumentados para proteção cardiovascular na elevação da espessura média da carótida.

SUMMARY BACKGROUND We investigated the serum annexin V and anti-annexin V levels and their relationship with metabolic parameters in patients recently diagnosed type 2 diabetic. METHODS A total of 143 patients recently diagnosed type 2 diabetes and 133 control subjects were included in the study. Body mass index (BMI), hs-CRP, HOMA-IR, carotid intima-media thickness, and serum levels of annexin V and anti-annexin V were investigated. RESULTS HOMA-IR, serum hs-CRP, and carotid intima-media thickness were found to be statistically significant. The Pearson correlation analysis revealed a statistically significant positive relationship between the carotid intima-media thickness and the annexin V level (r=0.29, p=0.006*). A statistically significant positive relationship was also detected between the Annexin V level and level of serum hs-CRP (r=0.29 p=0.006*). CONCLUSION A positive relationship was observed between the carotid intima-media thickness and annexin V at the end of our investigation. In this regard, we also believe that serum levels of annexin V may be increased for cardiovascular protection in the elevation of carotid intima-media thickness.
