Diagnosing Graves’ Disease and Non-Graves Hyperthyroidism Using TSH Receptor Antibody Test versus Non-TSH Receptor Antibody Test Methods of Diagnosis

Background: Differentiating Graves hyperthyroidism from the other causes of hyperthyroidism, using serum TRAb testing is essential step for diagnosis. Objectives: To study importance of TRAb in the diagnosis of Graves’ disease, distinguishing it from thyroiditis, and comparing it with clinical features and other tests such as TPOAb, US thyroid and thyroid scintiscan. Methods: A cross-sectional study was conducted on 120 patients attending endocrine clinicErbil city. Patients were studied on clinical feature basis and investigated with serum TRAb, TPOAb, TSH, Free T4, and Ultrasound examination of thyroid gland. Fisher exact test and Chi Square test of independence, Correlation coefficient and t-test of independence were used. Results: Fifty-two patients were found to have Graves’ disease;There was significant correlation between TRAb positivity and diagnosis of Graves’ disease p 0.05. Conclusion: A positive correlation was found between TRAb titer and positivity and no significant relation between TPOAb levels between Graves’ disease patients compared with thyroiditis patients, respectively.

Peripheral blood NKT cell number and function in patients with Graves disease and their correlation with hyperthyroidism

Objective:To assess the peripheral blood NKT cell number and function in patients with Graves disease and study their correlation with hyperthyroidism.Methods: The patients who were diagnosed with Graves disease in our hospital between May 2014 and September 2016 were selected as GD group, and 55 healthy volunteers who received physical examination in our hospital during the same period were selected as control group. Peripheral blood was collected to determine the number of CD3+CD56+NKT cells, and serum was collected to detect the contents of cytokines and thyroid function indexes.Results: Peripheral blood CD3+CD56+NKT cell number in Graves disease group was significantly lower than that in control group;serum IL-2, IFN-γ, TNF-α, IL-10 and TGF-β contents in GD group were significantly lower than those in control group and positively correlated with peripheral blood CD3+CD56+NKT cell number while IL-4, IL-5, IL-17, FT3, FT4, TPOAb, TgAb and TRAb contents were significantly higher than those in control group and negatively correlated with peripheral blood CD3+CD56+NKT cell number.Conclusion:The abnormal reduction of peripheral blood NKT cell number in patients with Graves disease can affect the balance of Th1/Th2 and Th17/Treg and increase the TRAb secretion to cause hyperthyroidism.

STUDY ON THE HETEROGENEITY OF TSH RECEPTOR ANTIBODIES IN THE PATHOGENESIS OF AUTOIMMUNE THYROID DISEASE

Objective To investigate the heterogeneity of TSH receptor antibodies ofpatients with autoimmune thyroid disease (AITD). Methods Six patients with heterogeneous TSH receptor antibodies were selected. The EBV-transformed B cell clones producing monoclonal anti-thyrotropin receptor antibodies were established from those selected patients. Results 125I-TSHbinding inhibiting immunoglobulin (TBII) values of the 6 patients ranged from 51 % to 89%. Thyroid stimulating antibody (TSAb) existed in patients No. 1,2, 4, 5 and 6 while only patients No. 1,2 and 3 had thyroid stimulation-blocking antibody (TSBAb ). After EBV-transformation of the peripheral B lymphocytes from those patients, we isolated and characterized 5 Bcell clones prepucing the TBII from patient No. 3 and 4 B cell clones prepucing TSAb from patient No. 6. Conclusion Autoantibodies against the us receptor are polyclonal and consist of heterogeneous populations with both stimulatory and inhibitory effects.

Thyroid dysfunction in Chinese hepatitis C patients: Prevalence and correlation with TPOAb and CXCL10

AIM: To investigate the relationship among pretreatment serum CXC chemokine ligand 10(CXCL10),thyroid peroxidase antibody(TPOAb) levels and thyroid dysfunction(TD) in Chinese hepatitis C patients.METHODS: One hundred and thirty-nine treatmentnaive genotype 1 chronic hepatitis C patients with no history of TD or treatment with thyroid hormones were enrolled in this study.Patients underwent peginterferon alfa-2a/ribavirin(Peg IFNα-2a/RBV) treatment for 48 wk,followed by detection of clinical factors at each follow-up point.Hepatitis C virus(HCV) antibodies were analyzed using microsomal chemiluminescence,and serum HCV RNA was measured by real-time PCR assay at 0,4,12,24 and 48 wk after the initiation of therapy and 24 wk after the end of therapy.To assess thyroid function,serum thyroid stimulating hormone(TSH),free thyroxine(FT4),free triodothyronine(FT3) and TPOAb/thyroglobulin antibody(TGAb) levels were determined using chemiluminescent immunoassays every 3 mo.Serum CXCL10 levels were determined at baseline.RESULTS: The prevalence of TD was 18.0%.Twentyone(84.0%) out of twenty-five patients exhibited normal thyroid function at week 24 after therapy.The rate of sustained virological response to Peg IFNα-2a/RBV in our study was 59.0%(82/139),independent of thyroid function.Pretreatment serum CXCL10 levels were significantly increased in patients with euthyroidstatus compared with patients with TD(495.2 ± 244.2 pg/m L vs 310.0 ± 163.4 pg/m L,P = 0.012).Patients with TD were more frequently TPOAb-positive than non-TD(NTD) patients(24.2% vs 12.3%,P = 0.047) at baseline.Three of the one hundred and fifteen patients without TPOAb at baseline developed TD at the end of treatment(37.5% vs 2.6%,P = 0.000).Female patients exhibited an increased risk for developing TD compared with male patients(P = 0.014).CONCLUSION: Lower pretreatment serum CXCL10 levels are associated with TD,and TD prevalence increases in female patients and patients who are positive for TPOAb at baseline.

Hypothyroidism during pregnancy: Controversy over screening and intervention

Thyroid hormones are critical for foetal neurological development and maternal health. Maternal hypothyroidism during pregnancy is associated with adverse impact on health of the mother as well as the progeny. Reduced thyroid hormone levels predispose the child to develop mental retardation and cognitive delay in early life. In the mother, hypothyroidism during pregnancy is associated with spontaneous abortion, placental abruption, preterm delivery and hypertensive disorders. Therefore, screening and therapeutic intervention is justified to prevent foetal as well as maternal co-morbidities. In view of impact of such a large-scale screening and intervention program on limited healthcare resources, it is debatable if a targeted rather than universal screening program will result in comparable outcomes. In addition, there is an ongoing debate regarding best evidence-based practice for the management of isolated hypothyroxinaemia, subclinical hypothyroidism and euthyroid women with autoimmune hypothyroidism. We have carried out a review of the literature; firstly, to determine whether universal screening for asymptomatic women in early pregnancy would be cost-effective. Secondly, we have retrospectively reviewed the literature to analyse the evidence regarding the impact of therapeutic intervention in women with subclinical hypothyroidism.

Evaluation of Serum Trace Elements and Vitamin Levels in Hashimoto’s Thyroiditis: Single Centre Experience from Turkey

Aim: To determine levels of serum trace elements and vitamins, and to find out possible correlations between these elements and vitamins with thyroid function tests and thyroid autoantibody levels in patients having Hashimoto’s thyroiditis (HT). Methods: The study included 51 premenauposal women with untreated HT, aged 18 to 56 years without any known chronic diseases or chronic medicine usage, and 27 healthy premenauposal women aged 19 to 42 years old. Trace elements (selenium, zinc, copper, iron levels) and vitamins [A, E, B12, 25-OH-D, 1,25(OH)2D and folic acid levels] were evaluated in patient and control groups. Results: Consequently, serum trace elements and vitamin B12 levels did not significantly differ in patients with HT and control group. Thyroid functioning tests and autoantibody levels did not show any correlation with the levels of trace elements, vitamin A, vitamin E and 25-OH vitamin D. A correlation was detected between vitamin B12 and Anti thyroid peroxidase levels. Conclusion: The negative correlation between vitamin B12 and Anti thyroid peroxidase levels may demonstrate the necessity to screen the patients with HT for atrophic gastritis. We believe that more comprehensive studies with larger sample sizes are needed in which patients are randomized according to their nutritional status.

Epidemiological and Clinical Aspects of Autoimmune Dysthyroidism in Internal Medicine at Aristide Le Dantec Hospital

Introduction: Autoimmune thyroiditis is relatively common in medicine. However, comprehensive studies are few in number, especially in Africa and particularly in Senegal. The aim of this study was therefore to determine the epidemiological, clinical, profile of Autoimmune Thyroid Diseases (OITD). Materials and Methods: This was a retrospective descriptive study from 2016 to 2019 of the records of patients who consulted or were hospitalised for autoimmune dysthyroidism in the internal medicine department of the Aristide Le Dantec Hospital. During this period, 1227 new consultations were recorded;they concerned three specialized consultations including endocrinology. The autoimmune origin was confirmed in 159 patients, i.e. in 45.69% of cases the AIDM then 12.96% of all consultations. The autoimmune origin was established on clinical, biological and immunological grounds. The data were collected from the medical records of the patients and recorded on a pre-established individual survey sheet taking into account the objectives of the study. The data collected was entered into the Sphinx V5 software on an established form. The analysis was carried out with the following software: Excel 2010 and Epi info 7.2. Results: Among this dysthyroidism, 159 patients had a confirmed autoimmune thyroid disease. On all new consultations, OITD represented 12.96% of internal medicine consultations. The sex ratio M/F was 0.18. The majority of our patients (57.86%) were aged between 25 and 44 years with extremes ranging from 11 to 63 years. In Graves’ disease, the notion of an irritative spine was found in 60.27% of cases. Signs of thyrotoxicosis were present in 92.7% of cases. There was a goiter in 81.1% of cases with a vascular character in 76.47% of cases. Anti-THR antibodies were positive in 96.15% of cases. Complications were noted in 9 patients (6.5%) such as cardiothyreosis in 8 patients (5.7%) and malignant orbitopathy noted in 1 patient (0.8%). In Hashimoto’s thyroiditis, signs of hypometabolism were evident in 87.50% of patients. Anti-TPO antibodies were positive in all patients. All patients had received thyroid hormone supplementation. Thyroid autoimmune disease was associated with other autoimmune diseases in 6.2% of cases. Conclusion: Autoimmune thyroiditis is common in our daily practice in Senegal;it is dominated by Grave’s disease. Hypothyroidism was the most common manifestation of Hashimoto’s thyroiditis. The inaccessibility of antithyroid antibody testing is an obstacle to the diagnosis and management of these conditions.

Association of stiff-person syndrome with autoimmune endocrine diseases

BACKGROUND Stiff-person syndrome(SPS)and its subtype,stiff limb syndrome(SLS),are rare neurological disorders characterized by progressive muscular rigidity and spasms.Glutamic acid decarboxylase(GAD)is the enzyme that catalyzes the production ofγ-aminobutyric acid(GABA),a major inhibitory neurotransmitter of the central nervous system.SPS is an autoimmune disease triggered by antiglutamic acid decarboxylase antibody(anti-GAD Ab).Clinically,anti-GAD Ab is associated with SPS,type 1 diabetes mellitus(T1DM),and other autoimmune diseases.AIM To investigate the link of autoimmune endocrine disorders with anti-GAD Ab in SPS subjects.METHODS This retrospective study was approved by the Institutional Review Board of Chang Gung Memorial Hospital,Taiwan.We collected the patients with SPS from January 2001 to June 2018.By reviewing 14 patients from medical records,we analyzed the clinical findings with coexisting autoimmune diseases,particularly diabetes mellitus and thyroid disease,which are associated with anti-GAD antibody titers or other immunological test results(anti-thyroid peroxidase and anti-nuclear antibodies).We also evaluated malignancies,major complications,and reported treatment to improve symptoms.Anti-GAD antibodies were measured using radioimmunoassay and enzyme-linked immunosorbent assay(ELISA).The cut-off values of these tests are<1 U/mL and<5 U/mL,respectively.RESULTS The median age of all patients was 39.3(range,28.0-54.0)years with a median follow-up period of 6.0(2.7-13.3)years.Five(35.7%)patients were female;twelve(85.7%)were diagnosed with classic SPS and two(14.3%)with SLS.The median age of onset of symptoms was 35.0(26.0-56.0)years with a median follow-up duration of 9.0(2.1-14.9)years in the classic SPS group;the SLS group had a median age of onset of 46.7 years and a shorter follow-up duration of 4.3 years.Among nine classic SPS patients who underwent the anti-GAD Ab test,three were anti-GAD Ab seropositive and each of these three patients also had T1DM,latent autoimmune diabetes in adults,and autoimmune thyroid disease,respectively.In contrast,other rare autoimmune diseases co-existed in six anti-GAD Ab seronegative SPS patients.None of the SLS patients had additional autoimmune diseases.CONCLUSION While typical clinical symptoms are crucial for the diagnosis of SPS,the presence of anti-GAD autoantibody may consolidate the diagnosis and predict the association with other autoimmune diseases.

Thyroid peroxidase antibody positivity and triiodothyronine levels are associated with pediatric Graves'ophthalmopathy

Background:Graves'ophthalmopathy(GO)occurs commonly in children with Graves'disease(GD).However,there are limited studies on the clinical manifestations and thyroid autoantibodies in pediatric GO.The aim of this study was to investigate the prevalence and risk factors of GO in childhood GD.Methods:Clinical and biochemical data from children and adolescents with GD were retrospectively reviewed.Eighty patients under 19 years of age were included in the present study.We compared the clinical and biochemical differences between patients with and without GO.Results:Thirty-nine percent of the patients had GO,and 81%of the GO patients were females.Of these,two patients showed unilateral GO.Triiodothyronine(T3)levels were higher in GO patients than in those without GO.Anti-thyroglobulin antibody and thyroid stimulating hormone receptor antibody titers were not significantly different between the two groups.Anti-thyroid peroxidase antibody(TPO Ab)positivity was 68%in the patients with GO and only 47%in the patients without GO.In multivariate regression analysis,high T3 levels and TPO Ab positivity were related to the presence of GO.Conclusion:In children and adolescents with GD,TPO Ab positivity and high T3 levels could act as predictive factors for the presence of GO.
