Clinical Observation of Levothyroxine Sodium Combined with Selenium in the Treatment of Patients with Chronic Lymphocytic Thyroiditis and Hypothyroidism and the Effects on Thyroid Function, Mood, and Inflammatory Factors

The purpose of this study was to investigate the therapeutic effects of levothyroxine sodium combined with selenium treatment and single levothyroxine sodium treatment on patients with chronic lymphocytic thyroiditis and hypothyroidism and to analyze the effects of different treatment regimens on patients’ thyroid function, mood, and inflammatory factors, with the aim of providing a reference for clinical treatment. The subjects of the current study were 138 chronic lymphocytic thyroiditis (CLT) patients with hypothyroidism admitted to our hospital from May 2016 to September 2019 and were randomly divided into a control group taking levothyroxine sodium (LT4) treatment and a combined group of LT4 combined with selenium treatment, with 69 cases each. Patients in both groups were evaluated for efficacy after 3 months of treatment, and their thyroid function was observed by total triiodothyronine (TT3), total thyroxine (TT4), thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), and thyroid globulin antibody (TGAb), and their mood changes were observed by Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores. The levels of inflammatory factors such as interleukin-2 (IL-2), interleukin-10 (IL-10), and tumor necrosis factor-α (TNF-α) were measured, and the occurrence of adverse drug reactions during the treatment period was observed and recorded in all patients. The results showed that the total effective rate of the combined group was significantly higher than that of the control group. The levels of TT3, TT4, TSH, TgAb, and TPOAb, SAS and SDS scores, and levels of inflammatory factors such as IL-2, IL-10, and TNF-α were significantly improved in both groups after treatment. Compared with the control group, TGAb, TPOAb, IL-2, TNF-α levels, and SAS and SDS scores decreased more and IL-10 levels increased more in the combined group, while the differences of other indexes were not statistically significant. This suggests that LT4 has certain efficacy in treating CLT with hypothyroidism, and the combined selenium treatment can improve the therapeutic effect of LT4 and can play a greater role in improving patients’ mood and immune and inflammatory responses.

Malignancy Rate of Bethesda Class III Thyroid Nodules Based on the Presence of Chronic Lymphocytic Thyroiditis in Surgical Patients

BackgroundHashimoto’s thyroiditis (HT), also known as chronic lymphocytic thyroiditis (CLT), may interfere with the accurate cytological diagnosis of thyroid nodules. Recently, HT has been considered a premalignant condition for thyroid cancer development. The diagnosis of atypia of undetermined significance/follicular lesions of undetermined significance (AUS/FLUS) thyroid nodules is challenging and evidence for the malignancy risk of AUS/FLUS thyroid nodules coexisting with CLT is scarce. Therefore, we assessed the malignancy risk of AUS/FLUS thyroid nodules according to the presence of background CLT.MethodsThis study included 357 surgically resected thyroid nodules with AUS/FLUS cytology. Cases with concomitant malignant nodules were excluded. CLT was defined based on the pathologic report after thyroid surgery.ResultsAmong 357 tumors, 130 tumors (36%) were confirmed to have coexisting CLT, and 170 tumors (48%) were determined to be malignant after thyroidectomy. Malignancy rates were similar in both groups (48% in each) regardless of background CLT (62/130 with CLT vs. 108/227 without CLT). In the group with CLT, thyroiditis was more frequent in the final pathology (12% with CLT vs. 1% without CLT, P = 0.003). In multivariate analysis, positive BRAFV600E mutation, highly suspicious sonographic features (K-TIRADS 5), and smaller thyroid nodules were significant factors for thyroid malignancies.ConclusionThe malignancy rate of thyroid nodules with AUS/FLUS cytology was comparable irrespective of the presence of underlying CLT.

Spontaneous (Hashimoto-like) chronic lymphocytic thyroiditis in a rhesus macaque (<i>Macaca mulatta</i>)

A case of a female, 10-year-old rhesus macaque (Macaca mulatta) with spontaneous chronic lymphocytic thyroiditis is presented. At necropsy, the thyroid gland was slightly enlarged, with up to 2 mm large, round, confluent, beige foci on the surface of both lobes. Histopathologic features resembled human Hashimoto's thyroiditis: multifocally, the interstitium was infiltrated by lymphocytes and variably sized lymphoid follicles. In the pituitary gland, there were increased numbers of large, basophilic cells throughout the adenohypophysis. Using a human electrochemiluminescence immunoassay (ECLIA), no autoantibodies against thyroglobulin, thyroid peroxidase, or thyroid-stimulating hormone receptor were detected.

To study cytomorphological details in case of autoimmune thyroiditis

Various smears were readied, air-dried and fixed in ethanol for staining by May-Grunwald-Giemsa stain and Papanicolaou staining strategy. A nitty gritty assessment of the cytologic smears was done and includes like cellularity, sum and nature of colloid, Hurthle cell change, anisonucleosis of follicular cells, range of receptive lymphoid cells and other incendiary cells like eosinophils, macrophages, goliath cells and epithelioid cells were noted. Thyroid capacity tests were finished utilizing COBAS E analyser.In our study we found, 82% Females whereas 18% Males. Lymphocytic Thyroiditis 42%, Granulomatous Thyroiditis 31 & Hashimoto’s Thyroiditis 27%. Types of swelling and diagnosis with painless 71 % and painful 29 %. Cross-sectional Observational Study. A total of 200 thyroiditis cases studied with detailed history, thorough clinical examination and relevant blood investigations like Thyroid Profile were being done. The various studies on the correlation of cytomorphological spectrum and antithyroglobulin antibodies in autoimmune thyroiditis cases all acreoss the globe have great variations in their findings.

RETROSTERNAL GOITRE WITH VARIED HISTOMORPHOLOGY: A CLINICOPATHOLOGICAL CASE REPORT

The term such as retrosternal or substernal is used when a goitre extends below thoracic inlet. Retrosternal goitre is rare and accounts for 5–20% of thyroidectomy patients. Majority of the patients present with symptoms of dyspnoea as in our case. Also, patients can come with change of voice, stridor and a huge swelling. Most of the cases of retrosternal goitre can be removed with conventional collar incision, however sternotomy may be required in few cases. Our patient was euthyroid at presentation and a right hemithyroidectomy was done for her. A detailed histopathological evaluation (HPE) showed evidence of long-standing Adenomatoid goitre with extensive hyalinization, thickened capsule and secondary degenerative changes in the right lobe of thyroid and evidence of chronic lymphocytic thyroiditis in the sections examined from the portion of isthmus. The procedure was uneventful. The patient was doing well after three months of clinical follow up.

Factors Affecting Central Node Metastasis and Metastatic Lymph Node Ratio in Papillary Thyroid Cancer

Objective Despite the growing evidence that metastatic lymph node ratio (MLNR) is a valuable predictor for the prognosis of papillary thyroid carcinoma, it has not yet been fully determined which factors give the ratio predictive value independent of the number of metastatic lymph nodes (MLNs). Study Design Retrospective cohort study. Setting A comprehensive cancer center. Methods Recurrence and clinicopathologic factors were analyzed in 2409 patients with papillary thyroid carcinoma who underwent total thyroidectomy and central node dissection. Results Cutoff values of MLNs ≥2 and MLNR ≥28.2% increased the recurrence risk (hazard ratio [95% CI], 9.97 [4.73-21.0] and 11.4 [5.53-23.3], respectively). Younger age, male sex, multifocality, tumor size, lymphatic and vascular invasion, and gross extrathyroidal extension positively correlated with MLN and MLNR (all P < .05). Meanwhile, lymphocytic thyroiditis negatively correlated with MLNR in female patients ( P < .001), by increasing total lymph node yields as compared with papillary thyroid carcinoma without lymphocytic thyroiditis. In multivariate analysis, younger age, tumor size, and lymphatic invasion remained significant in male and female patients for MLN and MLNR; lymphocytic thyroiditis was also significantly correlated with MLNR in female patients. Conclusion Our study demonstrates that MLN and MLNR are independently observed prognostic markers for tumor recurrence. However, lymphocytic thyroiditis in female patients seems to have lower MLNR by increasing total lymph node yields. In light of their association, a different cutoff for MLNR needs to be applied according to the presence or absence of underlying lymphocytic thyroiditis in the use of MLNR for predicting the recurrence. Level of Evidence: 4.
