Fifty-five adult Down's syndrome subjects resident at Northgate Hospital were screened for the presence of thyroid dysfunction. Approximately 50% of the subjects had clinical features suggestive of hypothyroidism, sufficient to require thyroid-function tests. Twenty-two per cent of the total suffered from some degree of hypothyroidism, and 16% had positive antibodies to thyroid tissue.

ABSTRACT Thyroid status was studied in 24 patients above the age of 40 years with Down's syndrome. Three patients had thyroid function tests indicating hypothyroidism. Eight patients had thyroid autoantibodies in serum and 8 patients had a higher than normal level of thyroid stimulating hormone in serum. None of the patients had figures indicating thyrotoxicosis. None of the patients showed any of the clinical signs usually seen in patients with hypothyroidism. It is concluded that biochemical tests indicating hypothyroidism are much more often seen in patients with Down's syndrome than in normal subjects and that thyroid status should be assessed in old patients with this disease.

Thyroid function tests are one of the most common endocrine panels in general practice because a good understanding of when to order them, indications for treatment are important for the optimal treatment of thyroid dysfunction. Thyroid-stimulating hormone (TSH) should be the rst test to be performed on any patient with suspected thyroid dysfunction and in follow-up of individuals on treatment. It is useful as a rst-line test because even small changes in thyroid function are sufcient to cause a signicant increase in TSH secretion. Thyroxine levels may be assessed in a patient with hyperthyroidism, to determine the severity of hyperthyroxinemia. Antithyroid peroxidase measurements should be considered while evaluating patients with subclinical hypothyroidism and can facilitate the identication of autoimmune thyroiditis during the evaluation of nodular thyroid disease. The measurement of TSH receptor antibody must be considered when conrmation of Graves’ disease is needed and radioactive iodine uptake cannot be done.

e15103 Background: Immune checkpoint inhibitors (ICI) frequently cause thyroid dysfunction. We performed a longitudinal analysis of thyroid function tests in a large, single-center cohort of patients with multiple cancer types receiving ICI. Methods: We performed a retrospective medical records review of consecutive patients treated with ICI from 1/1/2005 to 12/31/2018. We collected demographic and clinical data, including serial thyroid function tests. We compared overall survival between patients with normal and abnormal thyroid stimulating hormone (TSH) at baseline and after ICI initiation using Kaplan-Meier curves, log-rank tests, and multivariate Cox proportional hazards model. Results: A total of 910 patients were included: 63% male, 82% white, median age 67. The most common cancer types were lung (26%), kidney (18%), and melanoma (17%). ICI types were anti-PD1/L1 (78%), anti-CTLA-4 (7%), and combination ICI (15%). Normal baseline TSH and abnormal post-treatment TSH was associated with longer overall survival (median survival 26 months) compared to all other TSH permutations (median survival < 10 months) ( P< 0.001). This finding persisted after multivariate Cox regression adjustment for age, gender and cancer type (P < 0. 001), and also after sensitivity analysis censoring patients who died within 2 months after starting ICI. Conversely, abnormal TSH at baseline was associated with lower overall survival (median 8 months) compared to normal TSH at baseline (median 18 months) ( P< 0.001), which also persisted in multivariate analysis ( P< 0.001). Kidney and head and neck cancers (71% and 69%) were associated with increased development of thyroid dysfunction compared to melanoma, lung and other urological cancers (52%, 50% and 35%) ( P< 0.01). Conclusions: Although abnormal thyroid function after ICI initiation was associated with improved overall survival, pre-treatment thyroid abnormalities were associated with worse overall survival. Given the prevalence of thyroid abnormalities in the general population, further research into these observations is warranted.

BackgroundThyroid dysfunction is relatively common in patients with schizophrenia.This study seeks to determine the prevalence and pattern of thyroid dysfunction and thyroid antibodies presence in a group of adult psychiatric inpatients with chronic schizophrenia.MethodsThyroid function tests and thyroid antibodies measurement were performed on 88 patients hospitalized in Psichiatric Clinic of UHC “Mother Teresa” from december 2006 to december 2007.55 of them (62,5%) were females and 33 of them (37,5%) males. A median age of 43 years (range16 to 70 years) and a median duration of hospitalization of 10 years (range 1 to 30 years) was assessed.ResultsTAb were found in 22 patients (25%), of which 18 females and 4 males. 16% of them resulted with positive anticorps for Hashimoto Thyroiditis; 9% for Graves‘disease.According to thyroid function tests70% had normal test, 8% had elevated TSH: 3% of them with low thyroid hormones and 5% with normal thyroid hormones. 20% of cases had low TSH: 5% of them with high level of thyroid hormones, 15% with normal thyroid hormones. Hypothyroidism was more frequent in elderly patients ( > 60 years old), and in those treated with Risperidone. Most of cases (73%) with thyroid disorders resulted from endemic geographic areas. 37% of them mentioned familial history for thyroid pathology, and 23% for diabetes mellitus type 1.ConclusionThyroid abnormalities are common in patients with chronic schizophrenia.This fact call for caution in the use and interpretation of thyroid function tests in these patients.

Objective Amiodarone is used for the maintenance of sinus rhythm in patients with arrhythmias, but thyroid dysfunction (amiodarone-induced thyrotoxicosis (AIT) or amiodarone-induced hypothyroidism (AIH)) is a common adverse effect. As the onset of AIT and AIH may be unpredictable, the value of long-term regular monitoring of amiodarone treated patients for thyroid dysfunction is still uncertain. Design We retrospectively documented the frequency at which overt thyroid dysfunction was preceded by subclinical thyroid dysfunction. Methods We included 303 patients treated with amiodarone between 1984 and 2007. AIT was defined as a lowered TSH level with an elevated free thyroxine (FT4) and AIH was defined as an elevated TSH level with a decreased or subnormal FT4. Subclinical AIT was defined as a lowered TSH level with a normal FT4 and subclinical AIH as an elevated TSH level with a normal FT4. Results 200 men and 103 women, aged 62 ± 12.0 years, suffering from atrial (260) or ventricular (43) arrhythmias, were evaluated. During a median follow-up of 2.8 (1.0–25) years, 44 patients developed AIT and 33 AIH. In 42 (55%) patients who developed AIT/AIH, earlier thyroid function tests showed no subclinical AIT or subclinical AIH. In 35 (45%) patients, AIT/AIH was preceded by subclinical AIT or subclinical AIH (16/44 for AIT and 19/33 for AIH). Conclusions In a considerable proportion of patients who developed AIT/AIH, earlier thyroid function tests showed no subclinical AIT/AIH. Less than half of the patients with a subclinical event subsequently developed overt AIT/AIH. This study provides data to reconsider the yield of regular testing of thyroid function to predict overt thyroid dysfunction in amiodarone treated patients.

Thyroid hormones are important in the development of the fetus and the placenta as well as in maintaining maternal wellbeing. Thyroid disorders are common in the population as a whole, particularly in women, and therefore are common during pregnancy and the puerperium. Biochemical derangement of thyroid function tests are present in approximately 2.5–5% of pregnant women.

Context: Cognitive impairment is linked to thyroid dysfunction in various studies; however, the evidence is mixed. Aims: To determine cognitive function in the working population with abnormal thyroid function tests. Settings: Outpatient department of Medicine in a tertiary care hospital located in Central India. Design: Hospital-based, cross-sectional study. Methods and Material:100 patients between 15-64 years of age with different patterns of thyroid dysfunction were subjected to cognitive function testing via the Mini-Mental Status Examination (MMSE) questionnaire. Statistical analysis used: The data obtained was coded in a Microsoft Excel Worksheet and analyzed by SPSS software version 21. Results: 100 patients (11 % men and 89 % women) were included in the present study. The mean age of the study population was 37.11±8.76 years. 87 % had overt hypothyroidism, 6 % had subclinical hypothyroidism, 6 % had overt hyperthyroidism. The mean MMSE score of patients with abnormal thyroid function tests was 27.62 ±2.04 (Range 23-30). The mean MMSE score in patients with overt hypothyroidism was 27.54 ± 2.07, that of overt hyperthyroidism 28.33 ±1.03, and that of subclinical hypothyroidism was 27.67 ± 2.50. MMSE scores among different patterns of thyroid dysfunction were not found to be statistically significant. The MMSE scores between newly and previously diagnosed patients with thyroid dysfunction were not statistically significant. (28.3 ± 1.06 vs 27.54 ± 2.12). Conclusions: The results suggest no association between cognitive function and abnormal thyroid function tests in the working population.
