Objective To assess hormonal outcomes and thyroid hormone (TH) replacement after hemithyroidectomy (HT). Study Design Retrospective chart review. Setting Quaternary care hospital system. Methods A retrospective analysis was performed on patients who had an HT at Cleveland Clinic between 2000 and 2010 with outcomes assessed up to 5 years post-HT. Patients with overt hypothyroidism (OH; thyroid-stimulating hormone [TSH] >10 mIU/L, TSH >4.2 mIU/L on thyroid hormone [TH]), subclinical hypothyroidism (SH; TSH >4.2-10 mIU/L, no TH), or euthyroidism (EU; TSH 0.4-4.2 mIU/L, no TH) were compared. Patients with SH who returned to EU were compared to those who continued to have SH. For immediate start on TH, a receiver operating characteristic analysis was performed to determine dosage of TH above which suppression of TSH <0.4 mIU/L was predicted. Results We identified 335 patients (average age 51 years, 78% female, median follow-up of 50 months). Of the 210 not immediately started on TH, 32.4% were OH, 13.3% were SH, and 54.3% were EU. EU patients were younger (48 years), had more remaining gland, were less likely to have lymphocytic infiltrate, and had a lower preoperative TSH (1.2 mIU/L). In the SH group, 58.3% of patients normalized their TSH. With immediate TH start, 45% developed suppressed TSH. Those on LT4 >1.05 mcg/kg/d were more likely to suppress (sensitivity 89%). Conclusion Most patients post-HT will remain EU, and immediate start of TH may lead to TSH suppression. Those with SH may ultimately normalize TSH. These findings together suggest that observation may be a better option than TH replacement after HT.

Abstract Background Chronic kidney disease (CKD) is frequently accompanied by thyroid hormone dysfunction. It is currently unclear whether these alterations are the cause or consequence of CKD. This study aimed at studying the effect of thyroid hormone alterations on renal function in cross-sectional and longitudinal analyses in individuals from all adult age groups. Methods Individual participant data (IPD) from 16 independent cohorts having measured thyroid stimulating hormone, free thyroxine levels and creatinine levels were included. Thyroid hormone status was defined using clinical cut-off values. Estimated glomerular filtration rates (eGFR) were calculated by means of the four-variable Modification of Diet in Renal Disease (MDRD) formula. For this IPD meta-analysis, eGFR at baseline and eGFR change during follow-up were computed by fitting linear regression models and linear mixed models in each cohort separately. Effect estimates were pooled using random effects models. Results A total of 72 856 individuals from 16 different cohorts were included. At baseline, individuals with overt hypothyroidism (n = 704) and subclinical hypothyroidism (n = 3356) had a average (95% confidence interval) −4.07 (−6.37 to −1.78) and −2.40 (−3.78 to −1.02) mL/min/1.73 m2 lower eGFR as compared with euthyroid subjects (n = 66 542). In (subclinical) hyperthyroid subjects (n = 2254), average eGFR was 3.01 (1.50–4.52) mL/min/1.73 m2 higher. During 329 713 patient years of follow-up, eGFR did not decline more rapidly in individuals with low thyroid function compared with individuals with normal thyroid function. Conclusions Low thyroid function is not associated with a deterioration of renal function. The cross-sectional association may be explained by renal dysfunction causing thyroid hormone alterations.

Thyroid Hormone Levels

ABSTRACT Background: High blood pressure (BP) is a major health problem in Nigeria and the involvement of thyroid hormones in this condition has not been evaluated in this center. Objective: The objective of this study was to evaluate the proportion of patients with an essential hypertension who had abnormal thyroid hormone levels and the type of thyroid disorders commonly observed in this group of patients. Materials and Methods: A retrospective study of 94 patients (30 males, aged 30.4 ± 2 years and 64 females, aged 43.4 ± 1.3 years) with essential hypertension was carried out between January 2005 and December 2007. Demographic and other medical information were obtained from the health records. Analysis of laboratory results of triiodothyronine (T3), Thyroxine (T4), and thyroid stimulating hormone (TSH) were made. Results: Of the 94 patients evaluated, 26 (27.7%) had abnormal thyroid hormone levels, with 23.4% having hyperthyroidism, 4.3% had sub-clinical hypothyroidism and none had overt hypothyroidism. Of the 26 subjects with abnormal thyroid hormone levels, 18 (69.2%) were females while 8 (30.8%) were males. Out of the 18 female subjects with abnormal thyroid hormone levels, 16 had hyperthyroid levels while 2 had sub-clinical hypothyroid levels. Out of the 8 male patients, 6 had hyperthyroid hormone levels while 2 had sub-clinical hypothyroid levels. Conclusion: Thyroid hormone abnormalities are common in patients with essential hypertension. Hyperthyroidism was the most common thyroid disorder observed. Young patients presenting with essential hypertension should be screened for thyroid hormone abnormalities since they can best be managed by treating the underlying causes.

Abstract Purpose: To evaluate the association between thyroid echogenicity and heterogeneity seen on ultrasonography (US) and thyroid function in pediatric and adolescent populations with autoimmune diffuse thyroid diseases (AITD).Methods: From 2000 to 2020, we reviewed thyroid ultrasound (US) images and thyroid function statuses in 133 children and adolescent AITD patients. Our review of the images focused on decreased echogenicity and heterogeneity, which were classified into four grades.Results: Among patients with overt hypothyroidism or overt hyperthyroidism, 94.2% (65/69) showed a US grade of 3 or 4. In patients with subclinical hyper/hypothyroidism or euthyroidism, 45.3% (29/64) showed grades 1 or 2. There were no overt hyper/hypothyroidism patients with US grade 1. When we compared US grades according to thyroid status, more severe thyroid dysfunction was significantly associated with higher US grade (p=0.047). Thyroid stimulating hormone (TSH) level differed significantly according to US grades when we evaluated hyperthyroid (p=0.035) and hypothyroid (p=0.027) states independently. 11 patients showed both US grade and thyroid function status changes on follow-up US.Conclusions: In children and adolescent AITD patients, there was an association between decreased echogenicity and heterogeneity on US and thyroid dysfunction.

Background: Screening of thyroid disorders in antenatal women during first trimester, to recommend management of thyroid disorder during pregnancy and to know the maternal and fetal outcome of such pregnancy.Methods: This is a prospective study for the incidence of thyroid disorder in early pregnancy and the outcome of such pregnancy. 100 cases were randomly selected from the antenatal clinic at a tertiary care hospital in India and after fulfilling the inclusion criteria they were subjected to screening for thyroid disorder till 13 weeks of pregnancy. TSH is often considered the “gold standard” for assessing thyroid function. If the participant had normal value then she was not subjected to follow up, but if abnormal, then follow up was done after 4-8 weeks, thyroid profile was repeated and if values were altered, they were medically managed and closely monitored. The obstetric and perinatal outcome of the pregnancy was noted.Results: In this screening study to detect and manage thyroid disorder, 100 antenatal women were selected randomly, from which 49 women where primigravidae and 51 women were multi-gravidae, 17 of them were of <20years, 54 were between 21 to 25 years. There was 5 percent incidence of thyroid disorder in the study group. There were 3 cases of hyperthyroidism and 2 cases of overt hypothyroidism which had poor fetal and maternal outcome on follow up.Conclusions: Our study shows that the evaluation of thyroid disorders in early pregnancy and timely intervention will lead to a decrease in the complications thereby improving the maternal and fetal outcome.

Background: Hemangioblastomas are benign neoplasms that consist of stromal cells and small blood vessels. They are highly vascular tumors and can arise throughout the central nervous system. This study aims to provide an overview of our experience with this rare tumor’s presentation, radiology, histopathology, and outcomes as literature regarding this pathology is sparse from our country. Methods: The study is a retrospective review of cases that were histopathology proven cases of spinal cord hemangioblastomas. The clinical characteristics of these patients were examined, and their presentation was recorded. The radiology was also reviewed to describe classic appearance on magnetic resonance imaging. A detailed review of immunohistochemistry was also performed and outcome was described. Results: A total of 25 cases of spinal hemangioblastomas were found in our records in the period of 2001–2019. There were 20 males (80%) and only 5 female patients (20%). Gross tumor fragments ranged in size from 0.24 cm2 to 10.5 cm2 (mean 3.28 ± 2.65). Histologically, tumor was composed of nests of large stromal cells with clear to vacuolated cytoplasm separated by thin-walled capillaries. Focal intratumoral hemorrhage was noted. No significant cytological atypia or mitotic figures were noted. Immunohistochemical stains were performed to confirm the diagnosis and exclude other tumors. Inhibin was tested in 20 cases and it was positive in 16 cases (80%). Neuron-specific enolase was positive in 6/8 cases. Cluster of differentiation (CD) CD68 was positive in 6/6 cases and vimentin in 4/4 cases. Glial fibrillary acidic protein (GFAP) and epithelial membrane antigen were performed in 14 and 8 cases, respectively, and all were negative. Cytokeratin AE1/AE3 was negative in 13/13 cases. CD34 highlighted vasculature in the 8 cases in which it was performed and was negative in tumor cells. Follow-up was available in 17 out of 25 cases and ranged from 12 months to 216 months (mean 61.8 ± 60.6 months). Recurrence occurred in 2 out of 17 (11.7%) patients for whom follow-up information was available. Conclusion: Our experience shows that spinal cord hemangioblastomas can be surgically removed in most cases with a low risk of recurrence. Most patients in our study were male and unlike other studies, none of our cases showed GFAP positivity.

Purpose: To determine the effect of intravenous mannitol on globe and orbital volumes. Methods: Retrospective chart review of a consecutive series of Cleveland Clinic Neurosurgical Intensive Care Unit patients who underwent computed tomographic imaging before and after intravenous mannitol administration. Volume measurements were performed according to a previously described technique by averaging axial image areas. Measurements before and after mannitol administration were compared using paired t-test. Results: Fourteen patients (28 eyes) met inclusion criteria. Average globe volume decreased 186 mm3 (-2.5%, p = 0.02) after mannitol administration, while average orbital volume increased 353 mm3 (+3.5%, p = 0.04). Average globe volume change for subjects with follow-up scan less than 4.7 hours (mean 1.9 hours; range 0.2-4.5 hours) after mannitol administration was -125 mm3 (-1.7%, p = 0.24) and average orbital volume change was +458 mm3 (+5.1%, p = 0.11). Average globe volume change after mannitol administration for those with follow-up more than 4.7 hours (average 13.9 hours, range 4.9-24.7 hours) was -246 mm3 (-3.3%, p = 0.05) and orbital volume change was +248 mm3 (+2.2%, p = 0.24). Dividing the study population into groups based on mannitol dose did not yield any statistically significant change. Conclusions: Human globe volume decreases after intravenous mannitol administration, while orbital volume increases. These volume changes occur during the time period when intraocular pressure normalizes, after the pressure-lowering effects of the drug. This novel volumetric information improves our understanding of mannitol’s mechanism of action and its effects on human ocular and periocular tissues.

Objective To evaluate the prevalence and natural course of autoimmune and non-autoimmune subclinical hypothyroidism (SH) in Down syndrome (DS) children and adolescents. Design Prospective multicenter study. Methods For the study, 101 DS patients with SH (TSH 5–10 mIU/L; FT4 12–22 pmol/L), aged 2–17 years at SH diagnosis were enrolled. Annual monitoring of TSH, FT4, BMI, height, and L-thyroxine dose was recorded for 5 years. Thyroid autoimmunity was tested at diagnosis and at the end of follow-up. Results Thirty-seven out of 101 patients displayed autoantibody positivity (group A); the remaining 64 were classified as non-autoimmune SH (group B). Group A was characterized by higher median age at SH diagnosis and by more frequent family history of thyroid disease (6.6 vs 4.7 years, P = 0.001; 32.4% vs 7.8%, P = 0.001 respectively), whereas congenital heart defects were more common in group B (65.6% vs 43.2%, P = 0.028). Gender, median BMI (SDS), height (SDS), FT4, and TSH were similar in both groups. At the end of follow-up: 35.1% of group A patients developed overt hypothyroidism (OH) vs 17.2% of group B (P = 0.041); 31.25% of group B vs 10.8% of group A became biochemically euthyroid (P = 0.02); and 37.8% of group A vs 51.5% of group B still had SH condition (P = 0.183). Logistic regression suggested autoimmunity (OR = 3.2) and baseline TSH values (OR = 1.13) as predictive factors of the evolution from SH to OH. Conclusions In DS children, non-autoimmune SH showed higher prevalence and earlier onset. The risk of thyroid function deterioration over time seems to be influenced by thyroid autoimmunity and higher baseline TSH values.

AimTo follow-up for 5 years thyroid status evolution in 127 girls with mild (TSH 5–10 mU/l) subclinical hypothyroidism (SH) of different etiologies.PatientsThe population was divided into two age-matched groups of 42 and 85 girls with either idiopathic (group A) or Hashimoto's thyroiditis (HT)-related SH (group B). Group B was in turn divided into three subgroups, according to whether SH was either isolated or associated with Turner syndrome (TS) or Down syndrome (DS).ResultsAt the end of follow-up the rate of girls who became euthyroid was higher in group A (61.9% vs 10.6%), whereas the rates of patients who remained SH (55.3% vs 26.2%), became overtly hypothyroid (30.6% vs 11.9%) or required levothyroxine (l-T4) therapy (63.5% vs 23.8%) were higher in group B. Among the girls of group B, the risk of remaining SH or developing overt hypothyroidism was higher in the subgroups with TS or DS than in those with isolated HT.ConclusionsLong-term prognosis of mild and idiopathic SH is frequently benign, even though a l-T4 treatment may be needed throughout follow-up in almost a quarter of cases; long-term prognosis is different in the girls with either idiopathic or HT-related SH; and the association with either TS or DS impairs the outcome of HT-related SH.

AbstractTo evaluate the association between thyroid echogenicity and heterogeneity seen on ultrasonography (US) and thyroid function in pediatric and adolescent populations with autoimmune diffuse thyroid diseases (AITD). From 2000 to 2020, we reviewed thyroid ultrasound (US) images and thyroid function statuses in 133 children and adolescent AITD patients. Our review of the images focused on decreased echogenicity and heterogeneity, which were classified into four grades. Among patients with overt hypothyroidism or overt hyperthyroidism, 94.2% (65/69) showed a US grade of 3 or 4. In patients with subclinical hyper/hypothyroidism or euthyroidism, 45.3% (29/64) showed grades 1 or 2. There were no overt hyper/hypothyroidism patients with US grade 1. When we compared US grades according to thyroid status, more severe thyroid dysfunction was significantly associated with higher US grade (p = 0.047). Thyroid stimulating hormone (TSH) level differed significantly according to US grades when we evaluated hyperthyroid (p = 0.035) and hypothyroid (p = 0.027) states independently. 11 patients showed both US grade and thyroid function status changes on follow-up US. In children and adolescent AITD patients, there was an association between decreased echogenicity and heterogeneity on US and thyroid dysfunction.

Abstract Objectives. Given the high prevalence of subclinical hypothyroidism (SCH), defined as high thyroid stimulating hormone (TSH) and normal free thyroxine (FT4), and uncertainty on treatment, one of the major challenges in clinical practice is whether to initiate the treatment for SCH or to keep the patients under surveillance. There is no published study that has identified predictors of short-term changes in thyroid status amongst patients with mild elevation of TSH (4.5–10 mIU/L). Subjects and Results. A cohort study was conducted on patients with SCH detected through a general population screening program, who were followed for six months. This project identified factors predicting progression to hypothyroid status, persistent SCH and transient cases. A total of 656 participants joined the study (431 controls and 225 were patients with SCH). A part of participants (12.2%) developed biochemical hypothyroidism during the follow-up, while 73.8% of the subjects became euthyroid and the remained ones (13.4%) stayed in the SCH status. The incidence of overt hypothyroidism for participants with TSH above 6.9 mIU/L was 36.7%, with incidence of 42.3% for females. Anti-thyroid peroxidase antibodies (TPO) positivity is an important predictor of development of hypothyroidism; however, it could be also positive due to transient thyroiditis. Conclusions. It can be concluded that females with TSH above 6.9 mIU/L, particularly those with free triiodothyronine (FT3) and FT4 in the lower half of the reference range, are more likely to develop biochemical hypothyroidism. Therefore, it is recommended to give them a trial of levothyroxine replacement. It is also recommended to repeat TSH after six months for male subjects and participants with baseline TSH equal or less than 6.9 mIU/L.
