The Effect of Selenium Supplementation on Acute Phase Reactants and Thyroid Function Tests in Hemodialysis Patients

Background & Objective: Subacute Granulomatous Thyroiditis (De Quervain’s Thyroiditis) is an acute painful inflammatory disease of the thyroid. We aimed to investigate easily accessible and cheap hemogram based parameters of Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR), and Mean Platelet Volume (MPV) in the follow up of inflammatory thyroid disease. Methods: Patients admitted to Sakarya University Education and Research Hospital Endocrinology and Metabolism Outpatient Clinic and diagnosed as Subacute Granulomatous Thyroiditis between May 2017 and November 2018 were included in the study. Hemogram, thyroid function tests and acute phase values of these patients were recorded and compared with the values after treatment and disease recovery. On the sixth month, thyroid function tests were repeated and the rate of permanent hypothyroidism was screened. The relationships between initial hemogram parameters and acute phase reactants were evaluated. Results: Total 71 patients were included in our study. 60 (84.5%) were female and 11 (15.5%) were male. The F/M ratio was found to be 6/1. Mean age was 43 ± 9.95 years. Receiver Operating Characteristics (ROC) Curve Analysis was performed and values for Area Under the Curve (AUC) for NLR and PLR, respectively, were 0.739 (95% CI 0.657-0.820 p<0.0001) and 0.772 (95% CI 0.694-0.850 p<0.0001), which are significant and associated with disease activity. However, the AUC for MPV parameter was: 0.578 (95% CI 0.484-0.672 P: 0.10) and was not significant. The cut off values defined as 2.4 (80% sensitivity and 51% specificity) for NLR and 146.84 (83% sensitivity and 54% specificity) for PLR for the acute phase of the disease. In the Correlation Analysis, NLR and PLR values were significantly correlated with ESR and CRP parameters, which are the most commonly used acute phase reactants. Conclusion: According to the present study, we believe that the NLR and PLR parameters will be of benefit in the follow-up the disease, accurately demonstrate the inflammatory load in the acute phase of the disease, and correlate with the common acute phase reactants. doi: https://doi.org/10.12669/pjms.36.2.1063 How to cite this:Cengiz H, Varim C, Demirci T, Cetin S.

Introduction: Non-thyroidal illness syndrome (NTIS) can be defined as afunctional impairment of the hypothalamic-pituitary-thyroid axis accompanied by signs of non-thyroidal disease with changes in thyroid stimulating hormone (TSH), free T3 (fT3) and free T4 (fT4) levels. NTIS and thyroid hormone levels in this syndrome are thought to be related with mortality. This study was performed to evaluate the relationship between hormone levels and mortality in this syndrome. Methods: The 5-year mortality data of patients who were hospitalized in the first 6 months of 2014 and whose thyroid hormone levels could be checked twice within 5 years were evaluated. In our study conducted with 405 patients whose thyroid function tests was repeated, the follow-up period was 5 years. Biochemical parameters including thyroid function tests were sent from all patients. NTIS was defined as a condition in patients with low fT3 levels (<2.5 pg/mL) and TSH levels within the normal range (0.38-5.33 mIU / L). Results: 128 patients died, and the number of surviving patients was 277 during the follow-up period. Positive acute phase reactants such as CRP, sedimentation, ferritin was high and albumin (negative acute phase reactant) and fT3 levels were low in patients who died. In addition, these changes in biochemical values were statistically significant. The mortality rate was increased in patients with low fT3 and high fT4 levels. In the follow-up period, changes in TSH levels were not significantly associated with mortality. Conclusion: Both the decrease in fT3 levels and the increase in fT4 levels can be used as predictors and independent risk factors for long-term mortality risk in chronically ill and hospitalized patients with NTIS.
