The Effects of Corticosteroid and Nonsteroid Anti-Inflammatory Therapies on Permanent Hypothyroidism Occurring After the Subacute Thyroiditis.

OBJECTIVE: Subacute thyroiditis(SAT) is an acute inflammatory, self-limited, and destructive disease of the thyroid gland. Although it is a temporary disease, it has permanent consequences. We aim to investigate the influences of the treatment choice on permanent hypothyroidism occurring after SAT and whether there are predictive factors for the development of permanent hypothyroidism. METHODS: We retrospectively investigated 57 SAT patients admitted to our tertiary hospital between 2017 and 2019. After excluding 6 patients, demographic, clinical, laboratory, and imaging findings of 36 patients treated with NSAIDs and 15 patients treated with corticosteroids were compared. The median duration of follow-up was 4 (3.5-5.5) years. RESULTS: Permanent hypothyroidism occurred in 16 patients (31.4%) of 51 patients. It developed at a significantly higher rate in NSAID users (p=0.019). There was no significant difference in the occurrence of transient hypothyroidism and recurrence (p=0.472, p=0.082). The early maximum TSH values were strongly associated with permanent hypothyroidism. The Odds Ratio (OR) value was 2.59 (95% CI = 1.26 - 5.33, p=0.009), Nagelkerke R2 = 0.821. The early maximum TSH level had a predictive value, with an AUC of 0.966 for post-SAT permanent hypothyroidism (p<0.001). The cutoff values for the early maximum TSH were 9.07uIU/ml (81.3% sensitivity, 100% specificity), and 7.05 uIU/ml (87.5% sensitivity, 94.3% specificity). CONCLUSION: Corticosteroid therapy is significantly effective in preventing permanent hypothyroidism from developing after SAT. The early maximum TSH values are an indicator for the prediction of the development of permanent hypothyroidism.

Evaluation of corneal endothelium and correlation with disease severity in patients with Graves' ophthalmopathy: A specular microscopy-based study.

PURPOSE: To investigate the possible corneal endothelial damage in Graves' ophthalmopathy (GO) and its relationship with GO activity. METHODS: This cross-sectional study included 101 eyes of 55 patients with GO. Each eye was assigned a specific clinical activity score (CAS). Accordingly, they were classified as active (CAS ≥ 3) or inactive (CAS< 3). The corneal endothelium was measured using a non-contact specular microscope (Tomey EM-4000; Tomey Corp.). Endothelial cell density (ECD), average cell area (ACA), standard deviation of cell area (SD), coefficient of variation in cell area (CV), hexagonal cell ratio (HEX), and central corneal thickness (CCT) were recorded. RESULTS: Among the eyes included in the study, 71 had inactive GO and 30 had active GO. ACA and HEX levels were lower (p<0,001) and CV values were higher (p<0.001) in patients with GO than in healthy subjects. Corneal endothelial cell morphology was altered in active GO compared to inactive GO. The SD (p = 0,009) and CV (p<0,001) were significantly higher in active GO than in inactive GO. When the parameters examined were correlated with CAS, a statistically significant positive correlation was observed between proptosis (p = 0,036, r = 0,385) and CV (p = 0,001, r = 0,595). CONCLUSION: Our study confirmed that morphological changes occur in the corneal endothelium of patients with GO. CV and SD values, in conjunction with CAS, can be used as non-invasive and quantitative indices to examine the activity status of GO. The demonstration of endothelial changes even in GO eyes with low CAS may be considered an incentive to include non-contact specular microscopy in the routine clinical evaluation of all patients with GO.

Effects of Treatment Adherence on Quality of Life in Hypoparathyroid Patients.

OBJECTIVES: This study aimed to evaluate the current situation of hypoparathyroid patients and to investigate the relationship between treatment adherence and quality of life. STUDY DESIGN: Prospective, multicentre study. METHODS: Adult patients presenting with the diagnosis of hypoparathyroidism to 20 different endocrinology clinics were included. They were receiving conventional therapies for hypoparathyroidism, using calcium, active vitamin D, and magnesium. We collected data on demographic features, disease- and treatment-related information, and results of routine laboratory tests, treatment adherence, and presence of complications. Beck Depression Inventory, Beck Anxiety Inventory, and Short Form-36 quality of life assessments were administered. RESULTS: Among the 300 patients studied, 60.7% were adherent to their treatment, and 34.1% had complications. Anxiety and depression scores were significantly higher in non-adherent versus treatment-adherent patients (p<0.001 and p=0.001, respectively). Most of the domains of quality-of-life scores were also significantly lower in non-adherent patients. Both anxiety and depression scores showed significant, negative correlations with serum calcium and magnesium concentrations (r=-0.336, p<0.001 and r=-0.258, p<0.001, respectively). CONCLUSIONS: Nearly 40% of the patients were non-adherent to conventional treatment for hypoparathyroidism, and such patients had higher anxiety and depression scores and poorer quality of life scores. Conventional treatment might not be sufficient to meet the needs of patients with hypoparathyroidism. In addition to seeking new therapeutic options, factors influencing quality of life should also be investigated and strategies to improve treatment adherence should be developed.

The association between thyroid volume, L-thyroxine therapy and hepatocyte growth factor levels among patients with euthyroid and hypothyroid goitrous and non-goitrous Hashimoto's thyroiditis versus healthy subjects.

OBJECTIVE: Hashimoto's thyroiditis (HT) is the most common etiology of hypothyroidism in regions where iodine deficiency is not a concern. To date, many clinical investigations have been conducted to elucidate its pathogenesis. Several growth factors have been shown to have a role in its development. Hepatocyte growth factor (HGF) is one of the aforementioned molecules. We aimed to demonstrate whether HGF is responsible for HT and goiter development. Also, we aimed to test the hypothesis that levo-thyroxine sodium therapy will suppress HGF levels. MATERIALS AND METHODS: Sixty-one premenopausal women who were admitted to our outpatient clinic between November 2010 and September 2011 were enrolled. Three groups were determined according to their thyroid function tests (TFTs) as euthyroid Hashimoto's, control and subclinical hypothyroid Hashimoto's groups. Basal TFTs, anti-thyroid peroxidase (anti-TPO), anti-thyroglobulin (anti-tg), thyroid ultrasonography (USG) and HGF were studied and recorded. Subclinical hypothyroid HT patients received levo-thyroxine sodium replacement therapy, and were re-assessed for the same laboratory and radiologic features after a median 3.5 month follow-up. RESULTS: Basal HGF levels were not different between groups. In the subclinical hypothyroidism group, HGF levels (752.75 ± 144.91 pg/ml vs. 719.37 ± 128.05 pg/ml; p = 0.496) and thyroid volumes (12.51 ± 3.67 cc vs. 12.18 ± 4.26 cc; p = 0.7) before and after treatment did not change significantly. No correlations were found between HGF and other parameters. HGF levels were similar between subjects with nodular goiter and normal thyroid structure. CONCLUSIONS: HGF was not shown to be associated with HT and goiter development. In addition, levo-thyroxine sodium replacement therapy did not alter serum HGF levels significantly.

A case of Madelung's disease accompanied by Klinefelter's syndrome.

UNLABELLED: Madelung's disease is a rare fat metabolism disorder characterised by benign multiple symmetric, encapsulated lipomatosis. The exact cause of the disease is unknown; it may be associated with chronic alcoholism and mutations in mitochondrial DNA (A8344G), but there have been cases without these factors reported in the literature. A 29-year-old man with a 6-year history of diabetes mellitus was admitted to our hospital for poorly regulated diabetes and decreased libido. He was not an alcohol consumer. His family history was unremarkable. Physical examination revealed that he had a eunuchoid body shape. There was a symmetric excess fat accumulation in his submandibular, deltoid, nuchal, suprapubic and inguinal areas. He was diagnosed with Madelung's disease, and imaging studies supported the diagnosis. Hormonal evaluation revealed a hypergonadotropic hypogonadism. Karyotype analysis revealed a 47,XXY mutation. Genetic research showed no mitochondrial DNA mutation. Metabolic disorders, such as diabetes mellitus, hyperlipidaemia, hyperuricaemia and liver disease, endocrine gland diseases, such as hypothyroidism, and neurological diseases, such as polyneuropathy and cognitive disorders, may accompany Madelung's disease. The present study represents the first reported case of Madelung's disease accompanied by Klinefelter's syndrome.
