Exploring the relationship between Hashimoto's thyroiditis and male fertility:A meta-analytic and meta-regression perspective on hormonal and seminal factors

Objective:To explore the relationship between Hashimoto's autoimmune hypothyroidism(HT)and male fertility,focusing on hormonal and seminal factors.Methods:A systematic literature search was conducted across databases such as PubMed,Web of Science,EMBASE,Scopus,Cochrane,and Google Scholar,covering studies published from January 2000 to March 2024.Studies investigating the impact of HT on semen quality parameters and reproductive hormones were included.Pooled effect estimates were calculated using standard mean difference(SMD)and 95%confidence intervals(CI).Results:A total of 8 studies with 8965 participants were included.HT significantly affected semen quality and reproductive hormone levels.Specifically,there was a notable decrease in progressive morphology(SMD=-0.78;95%CI:-1.40 to-0.17;P=0.01)and sperm motility(SMD=-1.151;95%CI:-1.876 to-0.425;P=0.002).In addition,there were no significant changes in reproductive hormones,although there were elevated levels of luteinizing hormone(SMD=0.437;95%CI:0.000 to 0.874;P=0.050)and follicle-stimulating hormone(SMD=0.293;95%CI:-0.171 to 0.758;P=0.216),with a slight impact on testosterone levels(SMD=-1.143;95%CI:-2.487 to 0.200;P=0.095).Conclusions:This systematic review and meta-analysis provides robust evidence of the detrimental effects of HT on semen quality and reproductive hormones,underscoring the necessity for thorough evaluation and management of thyroid function in male infertility assessments.

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.

Vitamin D, selenium in type 2 diabetes and Hashimoto's thyroiditis: Is it effective?

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.

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.

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.

Presence of thyroid-associated ophthalmopathy in Hashimoto's thyroiditis

·AIM: To determine the prevalence of ophthalmopathy in Hashimoto’s patients and to make a comparison in subgroups of patients·METHODS: The study involved 110 Hashimoto’s thyroiditis patients and 50 control subjects attending to the endocrinology department of the hospital. Subgroup classification of patients was made as euthyroid,subclinic and clinic in Hashimato’s thyroiditis. All patients were evaluated by a single experienced ophthalmologist for the prevalence and characteristics of eye signs.·RESULTS:Theoverallprevalencesofeyechanges were22.7%(25 patients) in patients and 4%(2 persons) in control subjects respectively(P =0.002). In patients the most common symptom was retrobulbar eye pain with or without any eye movement. Thirteen patients had significant upper eyelid retraction(11.8%). Six patients had eye muscle dysfunction as reduced eye movements in up gaze. In control patients one person had proptosis and another had lid retraction. The clinical activity score and classification of the ophthalmopathy did not show any significant differences among subgroups.·CONCLUSION:Theeyesignsweremostlymild(22.7%)and the most common eye sign was the presence of upper eyelid retraction(11.8%). Additionally six patients had eye muscle dysfunction as reduced eye movements in up gaze. Therefore we recommend to make a routine ophthalmic examination in Hashimoto’s thyroiditis patients in order not to omit the associated ophthalmopathy.

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.

Hashimoto’s Thyroiditis and Encephalopathy

Although very rare, the literature describes cases of Hashimoto encephalopathy attesting to its occurrence. Affected patients present with seizures, stroke-like episodes, transient focal and global neurological deficits, and a variety of neuropsychiatric disturbance from dementia to hallucinations and psychosis. The encephalopathy evolves with concomitantly elevated anti-thyroid peroxidase antibodies, independent from hormonal thyroid function setting it apart from thyrotoxicosis and myxedema. A new patient reported with Hashimoto’s encephalopathy, in whom neurocognitive impairment and stroke-like onset of hemiparesis and hemiparkinsonism correlated with brain magnetic resonance imaging fused with positron emission tomography.

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.

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.

Hashimoto Thyroiditis:Simple Diagnosis with 2D-Shear Wave Elastography

Background: Hashimoto thyroiditis diagnosis is primarily established on clinical and laboratory findings;however, some hashimoto thyroiditis cases are euthyroid and seronegative. Moreover, these patients might also have normal conventional ultrasound findings. Aims: In our study, we aimed to distinguish the typical background characteristics of hashimoto thyroiditis using virtual touch tissue imaging quantification maps obtained with acoustic radiation force impulse imaging. Methods: Our study consisted of 28 hashimoto thyroiditis patients without characteristics of ultrasound findings and 28 healthy subjects. The thyroid parenchymal tissue mechanical properties were analyzed with the virtual touch tissue imaging quantification after ultrasound examination, and then related colored maps were obtained. Shear wave velocities were recorded (m/s) from the homogenous area where hardest and softest points were closest to each other on virtual touch tissue imaging quantification maps. The difference between the minimum and maximum shear wave velocities for each case (&Delta;v) was calculated and recorded. Results: Assessment of virtual touch tissue imaging quantification maps revealed a significant difference between hashimoto thyroiditis and control groups in terms of maximum SWV’s, but no significant difference was observed between the minimum shear wave velocities (p &Delta;v values were taken into account. In summary, the effects of chronic autoimmune thyroiditis can be distinguished by simply using &Delta;v on virtual touch tissue imaging quantification maps. When the cut-off value of &Delta;v was accepted 0.42, the diagnosis of hashimoto thyroiditis could be made with 88% accuracy. Conclusion: We suggest that shear wave velocities measurement on virtual touch tissue imaging quantification maps is a promising method in equivocal hashimoto thyroiditis cases, in which the diagnosis of hashimoto thyroiditis is unachievable with clinical, laboratory and conventional ultrasound findings.

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.
