Vitamin D and selenium for type 2 diabetes mellitus with Hashimoto’s thyroiditis:Dosage and duration insights

This letter discusses the publication by Feng et al.Iodine,selenium,and vitamin D are closely associated with thyroid hormone production in humans;however,the efficacy of selenium and vitamin D supplementation for type 2 diabetes mellitus(T2DM)patients with Hashimoto’s thyroiditis(HT)remains controversial.In the retrospective study we discuss herein,the authors highlighted significant improvements in thyroid function,thyroid antibodies,blood glucose,and blood lipid in T2DM patients with HT following addition of vitamin D and selenium to their antidiabetic regimens,underscoring the value of these supplements.Our team is currently engaged in research exploring the relationship between micronutrients and HT,and we have obtained invaluable insights from the aforementioned study.Based on this research and current literature,we recommend a regimen of 4000 IU/day of vitamin D and 100-200μg/day of selenium for over three months to six months for patients with HT,particularly for those with concurrent T2DM.

Effect of Hashimoto’s Thyroiditis on Efficacy of 131I Ablation Therapy in Intermediate- and High-Risk of Thyroid Papillary Carcinoma

Objective: The purpose of this study was to investigate the effect of Hashimoto’s thyroiditis on efficacy of 131I ablation in intermediate- and high-risk of thyroid papillary carcinoma patients. The findings will help to develop a personalized treatment plan for patients with thyroid papillary carcinoma complicated with Hashimoto’s thyroiditis. Material and Methods: From January 2016 to December 2020, patients who were diagnosed with intermediate- and high-risk PTC with lymph node metastasis were analyzed retrospectively, excluding patients with incomplete clinical data, distant metastasis, positive TGAb, TSH Results: A total of 525 patients (166 males and 359 females) were included in the study, including 368 patients in ER group (70.1%) and 157 patients in NER group (29.9%). Eleven factors including combining Hashimoto’s thyroiditis, pre-ablative Tg levels, sex, tumor diameter, extraglandular invasion, multifocal, bilateral lesions, central lymph node metastasis, lateral lymph node metastasis, lymph node metastasis rate, thyroglobulin were statistically different between ER group and NER group with significance at P Conclusion: Hashimoto’s thyroiditis, Ps-Tg level and lateral lymph node metastasis are potential predictors for short-term efficacy of 131I treatment in intermediate- and high-risk thyroid papillary carcinoma. Hashimoto’s thyroiditis, high Ps-Tg level and increased number of lateral lymph node metastasis reduce the efficacy of 131I therapy in patients with intermediate and high risk thyroid papillary carcinoma.

Coexistence of papillary thyroid microcarcinoma and mucosa-associated lymphoid tissue lymphoma in a context of Hashimoto's thyroiditis

Papillary thyroid cancer(PTC)represents 80%-85%of thyroid cancer and its prevalence has been rising in the last decades.Primary thyroid lymphoma(PTL)accounts for 3%of extranodal lymphomas and about 5%of thyroid malignancies,having a prevalence of one or two cases per million people.Mucosa-Associated Lymphoid Tissue lymphoma represents approximately30%of PTL.Both entities have an indolent course and a very good prognosis.Diagnosis is made by ultrasound and fine needle aspiration(FNA)or surgery specimen pathology.They have also been associated with Hashimoto’s thyroiditis(HT),but pathogenesis and its links remains to be known.Treatment remains controversial and surgery is generally accepted in cases of disease limited to thyroid,as the present.Patients with thyroid nodules should be observed and followed.If there is an enlargement by ultrasound or clinical symptoms,FNA should be performed promptly.Patients with HT deserve additional surveillance,since this condition is associated with both PTC and PTL.In this case,the management with surgery and radioactive iodine ablation therapy was effective for both entities.Patients with thyroid nodules should be properly evaluated with ultrasound and thyroid function tests.If there is an enlargement of the neck,reported by symptoms or ultrasound,it requires further investigation.HT is associated to both PTC and PTL so if the enlargement of the nodules is on this context additional tests such as FNA should be performed.In this case,the patient was managed with surgery and radioactive iodine ablation therapy and it was effective for both entities.

Clinical and Pathological Features of Riedel's Thyroiditis

Objective To evaluate the clinical and pathological features of Riedel's thyroiditis(RT),and current diagnostic and treatment methods for that disease.Methods Five RT cases identified by surgery and pathological examinations at Peking Union Medical College Hospital from 1985 to 2009 were analyzed and compared with the cases reported in the literature in terms of clinical and pathological features.Immunohistochemical staining of kappa and lambda light chains was carried out for RT tissues from all the five patients.Results All the five cases were females,aged 45-55 years.Elevation of serum thyroid autoantibodies was found in only one patient,who had longer disease duration than the others.Pathological examination revealed invasive fibrosclerosis of the thyroid follicles,thyroid capsule,and the surrounding tissues.In RT tissues,the number of cells containing lambda chains was a little higher than those containing kappa chains.Conclusions RT is a rare disease which might be more common in middle-aged females than in other populations.Pathological features include the destruction of thyroid follicle,extension into surrounding tissues by inflammatory cells and fibrous tissues.Immunohistochemical staining of kappa and lambda chains could help diagnose RT.

Intratumoral Bacteria Dysbiosis Is Associated with Human Papillary Thyroid Cancer and Correlated with Oncogenic Signaling Pathways

Emerging evidence suggests that microbial dysbiosis plays vital roles in many human cancers.However,knowledge of whether the microbial community in thyroid tumor is related to tumorigenesis remains elusive.In this study,we aimed to explore the microbial community in thyroid tissues and its contribution to papillary thyroid cancer(PTC).In parallel,we performed microbial profiling and transcriptome sequencing in the tumor and adjacent normal tissues of a large cohort of 340 PTC and benign thyroid nodule(BTN)patients.Distinct microbial signatures were identified in PTC,BTN,and their adjacent nontumor tissues.Intra-thyroid tissue bacteria were verified by means of bacteria staining,fluorescence in situ hybridization,and immunoelectron microscopy.We found that 17 bacterial taxa were differentially abundant in PTC compared with BTN,which included enrichment in PTC of the pathobionts Rhodococcus,Neisseria,Streptococcus,Halomonas,and Devosia,and depletion of the beneficial bacteria Amycolatopsis.These differentially abundant bacteria could differentiate PTC tumor tissues(PTC-T)from BTN tissues(BTN-T)with an area under the curve(AUC)of 81.66%.Microbial network analysis showed increased correlation strengths among the bacterial taxa in PTC-T in comparison with BTN-T.Immunefunction-corresponding bacteria(i.e.,Erwinia,Bacillus,and Acinetobacter)were found to be enriched in PTC with Hashimoto’s thyroiditis.Moreover,our integrative analysis revealed that the PTC-enriched bacteria had a positive association with key PTC-oncogenic pathway-related genes,including BRAF,KRAS,IRAK4,CTNNB1,PIK3CA,MAP3K7,and EGFR.In conclusion,our results suggest that intratumor bacteria dysbiosis is associated with the thyroid tumorigenesis and oncogenic signaling pathways of PTC.

Coeliac disease in Dutch patients with Hashimoto’s thyroiditis and vice versa

AIM: To define the association between Hashimoto’s thyroiditis and coeliac disease in Dutch patients. METHODS: A total of 104 consecutive patients with Hashimoto’s thyroiditis underwent coeliac serological tests (antigliadins, transglutaminase and endomysium antibodies) and HLA-DQ typing. Small intestinal biopsy was performed when any of coeliac serological tests was positive. On the other hand, 184 patients with coeliac disease were subjected to thyroid biochemical (thyroid stimulating hormone and free thyroxine) and thyroid serological tests (thyroglobulin and thyroid peroxidase antibodies). RESULTS: Of 104 patients with Hashimoto’s thyroiditis, sixteen (15%) were positive for coeliac serology and five patients with documented villous atrophy were diagnosed with coeliac disease (4.8%; 95% CI 0.7-8.9). HLA-DQ2 (and/or -DQ8) was present in all the five and 53 patients with Hashimoto’s thyroiditis (50%; 95% CI 43-62). Of 184 patients with coeliac disease, 39 (21%) were positive for thyroid serology. Based on thyroid biochemistry, the 39 patients were subclassified into euthyroidism in ten (5%; 95% CI 2-9), subclinicalhypothyroidism in seven (3.8%; 95% CI 1.8-7.6), and overt hypothyroidism (Hashimoto’s thyroiditis) in 22 (12%; 95% CI 8-16). Moreover, four patients with coeliac disease had Graves’ disease (2%; 95% CI 0.8-5) and one patient had post-partum thyroiditis. CONCLUSION: The data from a Dutch population confirm the association between Hashimoto’s thyroiditis and coeliac disease. Screening patients with Hashimoto’s thyroiditis for coeliac disease and vice versa is recom- mended.

Thyroid Cancers in the Thies Regional Hospital Center: Morpho-Epidemiological Study on 14 Cases

Introduction: Thyroid cancers are malignant cell proliferations developed at the expense of the thyroid gland, and which can spread from a distance. Most cancers appear in the form of anterior cervical swelling. Ultrasound and pathological examination allow the diagnosis of certainty. In Thiès, the studies carried out on thyroid cancers essentially focus on clinico-radiological and therapeutic aspects. We propose, through this study, to describe the epidemiological aspects and the morphological characteristics of thyroid cancers at Thiès Regional Hospital Center. Methodology: This is a retrospective, descriptive and analytical study conducted over a period of 3 years and 6 months, from January 2019 to June 2022. All patients with thyroid cancer confirmed by histological examination were included. Results: The patients who met the inclusion criteria were fourteen in number (14). The average age of patients was 40, 7 +/- 19 years old with extremes of 08 years and 75 years. Our series reports an 86% majority of women against 14% of men, with a sex ratio of 0.17. The isolated thyroid nodule was the most frequent mode of revelation of papillary thyroid cancers in our series, representing 54.6% of patients. The samplings received at the laboratory were essentially total thyroidectomy specimens. The tumor size varied between 1.5 cm and 14 cm. Papillary thyroid carcinoma was the most frequent histological type, with a frequency of 78.6%, followed by gallbladder carcinoma and squamous cell carcinoma. Conclusion: Thyroid cancers affect young subjects and are discovered at a late stage in our context.

Subclinical Hypothyroidism, Its Manifestations and Management a Case Report

Introduction: Thyroid states can be associated with psychiatric manifestations, be it hypothyroid, hyperthyroid or even euthyroid. The effect of depression is significant in subclinical hypothyroidism. Sometimes, its signs and symptoms are indistinguishable from Major Depressive Disorder. Our immunological system and early embryologic origins also play a role in the coexistence of other comorbidities like Pernicious Anemia. Case: A 35-year-old Hispanic female presented with significant low mood, somnolence, weight gain, increased hunger, cold intolerance and epigastric pain. It is important to note the variety of clinical manifestations of our hypothyroidism patient to understand its associations and help us with a better approach to treatment. Discussion: Standard approaches to treatment of Subclinical Hypothyroidism will depend mostly on laboratory findings such as TSH levels and free T4. Individualized therapy chosen for our patient was based on his mood symptoms, laboratory findings and coexistence of Pernicious Anemia. The use of daily 0.025 mg of levothyroxine, 10 mg of escitalopram oxalate and weekly injections of cyanocobalamin were treatments of choice. Conclusion: During follow up of our patient, we can conclude that Levothyroxine and Escitalopram Oxalate were able to improve hypothyroidism symptoms, reduce thyroglobulin and peroxidase antibodies and improve mood symptoms including cognitive functions. In addition to this, weekly cyanocobalamin injections were integrated into the management. As parietal cell antibodies decreased, gastrointestinal symptoms also disappeared. By addressing the concerns of our patient, we improved quality of care, and this is reflected in the patient’s wellbeing in physical and psychological.

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.

Diagnostic and Therapeutic Challenges of De Quervain Thyroiditis in Sub-Saharan Africa: Illustration with Two New Cases in Dakar

Introduction: De Quervain’s subacute thyroiditis is an inflammatory granulomatosis with clinical presentation some time atypical leading eventually to misdiagnosis or inadequate treatment. In our area, physician should be aware of this possible etiology in presence of recent and acute features of thyrotoxicosis with or without painful firm goiter. We illustrate this fact with two new observations from Sub-Saharan Africa. Observations: Our first patient is a 70-year-old Guinean woman presenting a painful nodular and hard goiter at palpation. Her history was recent in a context of deterioration of the general state with a sub clinical thyrotoxicosis syndrome. The diagnosis of probable malignant thyroid tumor was evoked initially and a thyroidectomy considered. She presented an important biological inflammatory syndrome and biological peripheral hyperthyroidism. Neck ultrasound examination showed heterogeneous patchy decreased echogenicity. The diagnosis of subacute De Quervain’s thyroiditis was set up. A corticosteroid therapy at a rate of 20 mg/day of prednisone was begun with a fast degression of dose. After 3 weeks of treatment, we noticed total clinical recovery normalization of biological parameters. The second observation was about a 52-year-old Senegalese women living in Bamako. She presented cervical pains evolving for 2 months in a context of flu-like syndrome associated with thyrotoxicosis and marked biological inflammatory syndrome. The thyroid ultrasound showed global heterogeneity with characteristic aspect of “geography map” leading to the diagnosis of subacute thyroiditis. A combination therapy with low dose of prednisone, &#223;-blockers and tranquillizers. We noticed fast disappearance of clinical and biological signs. At 5 mg per day of prednisone, there were moderate signs of relapse with rapid favorable evolution after few days under increased dose of prednisone up to 10 mg/day. Conclusion: De Quervain’s thyroiditis can appear under misleading features opening out to make wandering diagnosis. A good clinical evaluation coupled with hormonal and ultrasound thyroid examination may help for right management. The use of low dose of corticosteroid had enabled us to obtain a fast control of main clinical and biological abnormalities.

Advances in the relationship between Hashimoto’s thyroiditis and thyroid cancer

In recent years,the incidence of Hashimoto’s thyroiditis and thyroid cancer has shown a rapid growth trend.These two diseases have severely affected the public health.Many epidemiological studies have shown that thyroid cancer is often associated with Hashimoto’s thyroiditis.Hashimoto’s thyroiditis may promote the occurrence of thyroid cancer,as well as affecting the progression of the tumor,lymph node metastasis,and even the prognosis of patients.In this paper,the relationship between Hashimoto’s thyroiditis and thyroid cancer and the pathogenesis of thyroid cancer are reviewed regarding molecular mechanism,clinical pathology,and serology.

The Role of Vitamin D on Thyroid Antibodies in Patients with Chronic Autoimmune Thyroiditis

Vitamin D deficiency is a global problem,which has taken the form of a pandemic.Existing data indicate that vitamin D is not only a nutrient.It has also a hormone-specific activity.Vitamin D is characterized by anti-inflammatory and immunomodulatory properties.Chronic autoimmune thyroiditis is a disease of autoimmune genesis,in which lymphocytic infiltration gradually destroys thyroid tissue.There are some evidences about vitamin D deficiency and the development of chronic autoimmune thyroiditis.The article has reviewed the current literature about the impact and the benefits of vitamin D on thyroid antibodies levels.

Late Onset Peripheral Spondyloarthritis in Woman with Hashimoto’s Thyroiditis: A Case Report

Late onset peripheral spondyloarthritis is a particular clinical form of spondyloarthritis, occurring at the age of 50 years or older. Hashimoto’s thyroiditis (HT) is the most frequent autoimmune thyroid disorder responsible for considerable morbidity. HT is well known to be associated with many systemic autoimmune, it is less clear whether a similar association may also be present for spondyloarthritis. Here, we report a case of late onset peripheral spondyloarthritis in a 62-year-old African woman with a 12-year history of Hashimoto’s thyroiditis, a previously undescribed association in the literature. The diagnosis of Late onset peripheral spondyloarthritis was made according to the Assessment of SpondyloArthritis international Society (ASAS) criteria for peripheral spondyloarthritis (presence of arthritis, enthesitis and Human Leukocyte Antigen B27). She was treated with methotrexate and celebid. After 6 months of treatment, the evolution was favourable with an overall improvement in her symptomatology and quality of life. The coexistence of late onset peripheral spondyloarthritis and Hashimoto’s thyroiditis may be related to the presence of a genetic background predisposing to both diseases.
