Postpartum Thyroid Dysfunction

Rationale—Microsomal antibodies have been related to postpartum thyroid dysfunction and postpartum depression. Objectives—To detect the value of microsomal antibodies during gestation in a random population, as a risk factor for thyroid dysfunction and depression during the postpartum period. Main findings—The presence of microsomal antibodies was investigated in a random population of 293 women at 32 weeks' gestation. At the same time, postpartum thyroid function was assessed repeatedly in all women every six weeks up to 34 weeks' postpartum. Postpartum thyroid dysfunction, defined as the presence of abnormal TSH, in combination with abnormal fT4 and/or fT3 values, occurred in 21 women (7.2%) during the postpartum period. Depression was assessed using the Research Diagnostic Criteria without knowing the results of biochemical thyroid function tests. At 32 weeks' gestation there were 27 (9.2%) women with elevated microsomal antibody titres. Compared with microsomalantibody negative women at 32 weeks' gestation, these women had an RR of 20 for developing postpartum thyroid dysfunction and an RR of 1.7 for developing postpartum depression. Conclusions—Women with elevated microsomal antibody titres during gestation are particularly at risk for postpartum thyroid dysfunction, but only have a slightly increased risk for postpartum depression.

A growing body of evidence suggests that hypothyroidism and hyperthyroidism, either as overt or subclinical states, are associated with increased risk for cardiovascular disease (CVD). Except for the increased prevalence of lipid disorders, coagulation abnormalities, endothelial dysfunction, cardiac arrhythmias, ventricular hypertrophy and hypertension have been proposed as the most plausible pathways for this association, increased arterial stiffness (AS) may also play a role. Increased AS has emerged recently as an early indicator of CVD in various studies. On the other hand, thyroid dysfunction, mainly hypothyroidism (overt and subclinical) seems to be associated with increased AS, although data are heterogeneous, emerging from different populations, with various methodologies of AS assessment and with variable periods of observation. Restoration of thyroid function with L-thyroxin replacement seems to reverse AS parameters, whereas data on the effect of normalization of thyroid function in hyperthyroidism on AS are inconsistent. The present review provides insights on the association between AS and thyroid dysfunction and discusses the available data about potential benefits of the restoration of thyroid function on AS.

Background First-trimester care of maternal thyroid dysfunction has previously been shown to be poor. This study evaluates early management of thyroid dysfunction in pregnancy in Australia. Methods Patients reviewed by the Obstetric Medicine team for thyroid dysfunction from 1 January 2012 to 30 June 2013 were included. Data were collected on gestation at referral from the patient’s general practitioner to the antenatal clinic, information provided in the referral letter, thyroid function tests and thyroid medications. Results Eighty-five women were included in the study. At the time of general practitioner referral to antenatal services, 19% of women with preexisting thyroid disease had no thyroid function tested. Forty-three percent had an abnormal thyroid-stimulating hormone defined as being outside the laboratory-specific pregnancy reference range if available, or outside the level of 0.1–2.5 mIu/L in the first trimester, 0.2–3.0 mIu/L in the second trimester and 0.3–3.0 mIu/L in the third trimester. Only 21% of women increased their thyroxine dose prior to their first antenatal clinic review. Conclusion This study highlights that a significant proportion of women with known thyroid disease either have untested thyroid function in the first trimester or a thyroid-stimulating hormone outside of levels recommended by guidelines.

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.

Objective:To investigate whether previously reported increasing incidence of pregnancy-associated stroke (PAS) is observed in chart-validated register data in Finland. In an exploratory analysis, we studied risk factors for PAS.Methods:We performed a retrospective population-based cohort study and nested case-control study in Finland 1987-2016. The Medical Birth Register (MBR) was linked with the Hospital Discharge Register to identify women with incident stroke (ischemic stroke, cerebral venous thrombosis, intracerebral or subarachnoid hemorrhage) during pregnancy or puerperium. Cases were verified from patient records. Incidence of PAS over the study period, in 5-year age groups and pregnancy/postpartum period were calculated per number of deliveries. Three matched controls were selected for each case from MBR to compare risk factors.Results:After chart review, 29.6% (257/868) of cases were PAS. The incidence of PAS was 14.5 (95%CI: 12.8-16.3) per 100,000 deliveries. Incidence increased from 11.1 to 25.2 per 100,000 deliveries from 1987-1991 to 2012-2016 (p<0.0001). Incidence increased by age from 9.8 to 29.9 per 100,000 deliveries from ages 20-24 to ages >40 (p<0.0001). During early postpartum period, incidence was 5-fold greater compared to the first trimester. Maternal mortality was 6.6%. In the multivariable adjusted model, smoking beyond 12 gestational weeks (odds ratio [OR] 1.8, 95%CI: 1.2-2.7), migraine (OR 16.3, 95%CI: 5.3-49.8), and hypertensive disorders of pregnancy (OR 4.0, 95%CI: 2.5-6.3) were the most important risk factors for PAS.Conclusion:PAS incidence is increasing stressing the importance of careful pregnancy surveillance and risk factor management, particularly in older expectant mothers and extending to puerperium.Classification of Evidence:This study provides Class III evidence that smoking beyond 12 gestational weeks, migraine and hypertensive disorders of pregnancy are associated with an increased risk of PAS.

Disorders of thyroid function are common in pregnancy and have implications for foetal and maternal health. Thyroid autoimmunity, as evidenced by the presence of elevated levels of anti-thyroid antibodies (anti-TPO and anti-Tg antibodies) is associated with an increased risk of miscarriage, though the mechanism remains poorly understood. There has been considerable focus on the implications and optimal management of pregnant women with thyroid disease, especially those undergoing assisted reproduction. Pregnancy results in significant changes in thyroid physiology and these need to be understood by clinicians involved in the care of pregnant women. Guidelines for the use of thyroxine and target thyroid function tests have been produced by international bodies but it is recognised that these predominantly reflect expert opinion rather than established evidence-based practice. Importantly a number of key clinical trials have been performed to aid understanding, particularly of the consequences of hypothyroidism for mother and baby, and the effectiveness of thyroid hormone use in autoimmune and subclinical hypothyroidism. This review summarises the current knowledge base and guidance for practice relating to thyroid disorders in pregnancy and subfertility.

Background: Changes in thyroid function in normal pregnancy are well-documented but in complicated pregnancy like preeclampsia, very little is known. Studies have shown evidences of hypothyroidism in preeclampsia necessitating thyroid function tests to be done in preeclampsia. The study was done to analyze the fetomaternal outcome of preeclampsia with coexisting thyroid dysfunction.Methods: A cross-sectional analytical study was done over 18 months on 95 preeclamptic patients admitted at the antenatal ward and fetomaternal outcomes were analyzed according to thyroid status.Results: Out of 95 patients with preeclampsia, 42 (44.2%) had thyroid dysfunction. Among these 42 patients, 37 (38.9%) patients had subclinical hypothyroidism, 4 (4.2%) had overt hypothyroidism and 1 (1%) had hyperthyroidism. Severe preeclampsia was seen in 64.3% of the patients with thyroid dysfunction compared with 39.6% in euthyroid patients. The mean thyroid stimulating hormone (TSH) level was significantly higher and means free thyroxine (fT4) level was significantly lower in severe preeclampsia compared with non-severe preeclampsia. Complications like abruption, intrauterine fetal death (IUD), intrauterine growth restriction (IUGR), oligohydramnios, preterm deliveries, postpartum hemorrhage (PPH), low birth weight babies, birth asphyxia in babies and subsequent neonatal intensive care unit (NICU) admissions were significantly higher (p <0.05) in the preeclampsia patients with thyroid dysfunction in comparison with euthyroid ones.Conclusions: Hypothyroidism may be a modifiable risk factor for preeclampsia. Thyroid screening early in pregnancy may be helpful in predicting the occurrence of preeclampsia and timely thyroid hormone administration can reduce the maternal and perinatal morbidity and mortality associated with preeclampsia.

AbstractBackgroundPrader-Willi syndrome (PWS) is a genetic disorder due to loss of expression of paternally transcribed genes of the imprinted region of chromosome 15q11-13. PWS is characterized by peculiar signs and symptoms and many endocrine abnormalities have been described (growth hormone deficiency, hypogonadotropic hypogonadism). The abnormalities of thyroid function are discussed in literature and published data are discordant. The aim of our study was to report the thyroid function in patients with PWS to identify the prevalence of thyroid dysfunction.MethodsThyroid function tests were carried out in 339 patients with PWS, aged from 0.2 to 50 years. A database was created to collect personal data, anthropometric data, thyroid function data and possible replacement therapy with L-thyroxine. Subjects were classified according to thyroid function as: euthyroidism (EuT), congenital hypothyroidism (C-HT), hypothyroidism (HT – high thyroid-stimulating hormone [TSH] and low free thyroxine [fT4]), central hypothyroidism (CE-H – low/normal TSH and low fT4), subclinical hypothyroidism (SH – high TSH and normal fT4), and hyperthyroidism (HyperT – low TSH and high fT4).ResultsTwo hundred and forty-three out of 339 PWS patients were younger than 18 years (71.7%). The prevalence of thyroid dysfunction was 13.6%. Specifically, C-HT was found in four children (1.18%), HT in six patients (1.77%), CE-H in 23 patients (6.78%), SH in 13 patients (3.83%), and HyperT in none. All other subjects were in EuT (86.4%).ConclusionsHypothyroidism is a frequent feature in subjects with PWS. Thyroid function should be regularly investigated in all PWS patients both at the diagnosis and annually during follow-up.

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.
