Randomized Trial Comparing Two Algorithms for Levothyroxine Dose Adjustment in Pregnant Women With Primary Hypothyroidism

Abstract Context Regulation of maternal thyroid hormones during pregnancy is crucial for optimal maternal and fetal outcomes. There are no specific guidelines addressing maternal levothyroxine (LT4) dose adjustments throughout pregnancy. Objective To compare two LT4 dose-adjustment algorithms in hypothyroid pregnant women. Design Thirty-three women on stable LT4 doses were recruited at <10 weeks gestation during 38 pregnancies and randomized to one of two dose-adjustment groups. Group 1 (G1) used an empiric two-pill/week dose increase followed by subsequent pill-per-week dose adjustments. In group 2 (G2), LT4 dose was adjusted in an ongoing approach in micrograms per day based on current thyroid stimulating hormone (TSH) level and LT4 dose. TSH was monitored every 2 weeks in trimesters 1 and 2 and every 4 weeks in trimester 3. Setting Academic endocrinology clinics in Washington, DC. Main Outcome Measure Proportion of TSH values within trimester-specific goal ranges. Results Mean gestational age at study entry was 6.4 ± 2.1 weeks. Seventy-five percent of TSH values were within trimester-specific goal ranges in G1 compared with 81% in G2 (P = 0.09). Similar numbers of LT4 dose adjustments per pregnancy were required in both groups (G1, 3.1 ± 2.0 vs G2, 4.1 ± 3.2; P = 0.27). Women in G1 were more likely to have suppressed TSH <0.1 mIU/L in trimester 1 (P = 0.01). Etiology of hypothyroidism, but not thyroid antibody status, was associated with proportion of goal TSH values. Conclusions We compared two options for LT4 dose adjustment and showed that an ongoing adjustment approach is as effective as empiric dose increase for maintaining goal TSH in hypothyroid women during pregnancy.

Background: Iodine need is increased during pregnancy and its deficiency can lead to complications in mother and fetus. The latest international guidelines have recommended a higher intake of iodine. Iran has implemented a national salt iodization program since 25 years ago, and the general population is iodine-sufficient. However, recent studies have shown that a significant proportion of pregnant women have urinary iodine concentration (UIC) below the recommended range of 150 - 250 µg/L. Based on the results of these studies, iodine supplement during pregnancy is widely used, but this practice is controversial. Objectives: The aim of this study was to evaluate the necessity for iodine supplementation in pregnant women living in Shiraz, an iodine-replete area. Methods: In this cross-sectional case-control study, UIC and thyroid-stimulating hormone of 174 pregnant women taking 150 µg/day iodine (group 1) were compared with 124 pregnant women not taking the supplement (group 2). The proportion of women with UIC below the recommended level in each group was also determined. UIC of the women in different trimesters in each group was also investigated and compared. Results: Mean UIC in groups 1 and 2 was 175.71 ± 56.43 µg/Land 122.5 ± 44.37 µg/L and this difference was significant (P = 0.006). Also, 56% of women in group 2 and 24 % in group 1 had UIC below the recommended value (P < 0.01). Mean UIC in both groups decreased with advancing gestational age. In group 1, mean UIC remained in the recommended range, whereas in group 2, it decreased to less than 100 µg/L. Conclusions: In areas covered by the national salt iodine implementation program, it is necessary to recommend iodine supplement to pregnant women to prevent iodine insufficiency.

The primary aim of this study was to compare the prevalence of subclinical hypothyroidism (SCH) using two different cut-off levels for TSH values (≥2.5 mIU/L versus ≥4.1 mIU/L). The secondary objective was to analyze the clinical-biochemical characteristics in women with and without SCH. This was a retrospective cross-sectional study. In total, 1496 Mexican women with infertility were included: Group 1, women with TSH levels ranging between 0.3 and 2.49 mIU/L, n = 886; Group 2, women with TSH between 2.5 and 4.09 mIU/L, n = 390; and Group 3, women with TSH ≥4.1 mIU/L n = 220. SCH prevalence was 40.7% (CI 95%: 38.3–43.3%) with TSH cut-off ≥ 2.5 mIU/L, and 14.7% (CI 95%: 12.7–16.5%) with TSH cut-off ≥ 4.1 mIU/L, (p = 0.0001). The prevalence of overweight was higher in Group 2 than in Groups 1 and 3. Thyroid autoimmunity, obesity and insulin resistance were higher in Group 3 than in Group 1 (p < 0.05). No other differences were observed between groups. Conclusions: The prevalence of SCH in our selected patients increased almost three times using a TSH cut-off ≥ 2.5 mIU/L compared with a TSH cut-off ≥ 4.1 mIU/L. Women with TSH ≥4.1 mIU/L compared with TSH cut-off ≤ 2.5 mIU/L more often presented with obesity, thyroid autoimmunity and insulin resistance.

Abstract Objectives Non-alcoholic fatty liver disease (NAFLD) is a common obesity-related comorbidity in childhood. In this study, we aimed to evaluate predictors of NAFLD by comparing clinical, endocrine and metabolic findings in obese children with and without hepatosteatosis. Methods Two hundred and eight obese children aged 6–18 years were included. The patients were divided into group 1 (patients with NAFLD, n=94) and group 2 (patients without NAFLD, n=114). Anthropometric measurements, pubertal stage, lipid profiles, fasting glucose and insulin, homeostatic model of assessment for insulin resistance (HOMA-IR), uric acid, total bilirubin, alanine aminotransferase (ALT), blood urea nitrogen, thyroid-stimulating hormone and free thyroxine parameters were compared retrospectively. Results The mean body weight, body mass index (BMI), height, tri-ponderal mass index (TMI), insulin, HOMA-IR, triglyceride, ALT and uric acid values were significantly higher, while high-density lipoprotein-cholesterol (HDL-C) values were significantly lower in group 1. The 70.7% of obese children with hepatosteatosis and 83.9% of those without hepatosteatosis were correctly estimated by parameters including age, gender, ALT, HDL-C, fasting insulin and uric acid values. Conclusions Since obesity-associated hepatosteatosis induces various long-term metabolic impacts in children, early detection is of critical importance. Age, gender, TMI, BMI, ALT, HDL-C, fasting insulin and uric acid values may help to predict the risk of hepatosteatosis. Besides, we assessed whether TMI compared to BMI does not have a better utility in estimating obesity-induced hepatosteatosis in children. This is the first study to show the association between TMI and hepatosteatosis in children.

Aim: to study the role of antiphospholipid antibodies (AРA) and genetic thrombophilia as a potential cause of the development or a component in the pathogenesis of early and late fetal growth retardation (FGR).Materials and Methods. There was conducted a prospective randomized controlled trial with 118 women enrolled. The main group consisted of 83 patients, whose pregnancy was complicated by FGR degrees II and III, stratified into two groups: group 1 – 36 pregnant women with early FGR, group 2 – 47 pregnant women with late FGR. Women were subdivided into subgroups according to the FGR severity. The control group consisted of 35 pregnant women with a physiological course of pregnancy. АРА were determined according to the Sydney antiphospholipid syndrome criteria by enzyme immunoassay (ELISA): against cardiolipin, β2 -glycoprotein 1, annexin V, prothrombin, etc. (IgG/IgM isotypes); lupus anticoagulant – by the three-stage method with Russell's viper venom; antithrombin III and protein C levels – by chromogenic method; prothrombin gene polymorphisms G20210A and factor V Leiden – by polymerase chain reaction; homocysteine level – by ELISA.Results. AРA circulation (medium and high titers), genetic thrombophilic defects and/or hyperhomocysteinemia were detected in 40 (48.2 %) patients with FGR, which was significantly higher than that in the control group (p < 0.05): in group 1 (41.7 % of women) AРA (30.6 %) and AРA with genetic thrombophilia or hyperhomocysteinemia (11.1 %) were revealed; in group 2 (51.1 % of women) AРA (21.3 %), AРA with hyperhomocysteinemia (4.3 %), genetic thrombophilia (25.5 %), and due to hyperhomocysteinemia (2.1 %) were found. No differences in prevalence of thrombophilia rate in patients were observed related to FGR severity, but a correlation between the FGR severity and AРA titers was found.Conclusion. Testing for the presence of AРA, genetic thrombophilia and hyperhomocysteinemia should be recommended for patients with FGR (including those with FGR in medical history), especially in the case of its early onset. It is recommended to determine the full AРA spectrum.

Aim: to assess the efficacy of biologically active additive Cystenium II as a component of combined antimicrobial treatment of acute cystitis or exacerbation of chronic cystitis and asymptomatic bacteriuria (ASB) in pregnant women. Patients and Methods: 65 pregnant women with urinary tract infections were enrolled. Group 1 included 22 women with acute cystitis or exacerbation of chronic cystitis and group 2 included 20 women with ASB. These women received standard antimicrobial therapy (fosfomycin trometamol 3 g) and Cystenium II (1 tablet twice daily with food for 14 days). The control group included 23 women with acute cystitis or exacerbation of chronic cystitis or ASB who received standard antimicrobial therapy only. Treatment results were evaluated after 14 days and 2 months. Results: complete resolution of cystitis occurred on days 2 and 3 in group 1 and days 4 and 5 in group 2. Eradication of causative agent as demonstrated by inoculation of urine samples after 14 days was reported in 77.3% of women in group 1, 70% of women in group 2, and 61% of women in group 3. Total treatment efficacy in group 1 was 81.9%, i.e., exacerbations of chronic cystitis were diagnosed in 3 women (13.6%), acute pyelonephritis in 1 woman (4.5%). Total treatment efficacy in group 2 was 90%, i.e., recurrence of ASB was diagnosed in 2 women (10%). Meanwhile, treatment efficacy in the control group was 56.5%, i.e., clinical exacerbation of chronic cystitis was diagnosed in 6 women (26%). Moreover, in 4 women (17.4%), the disease was complicated by acute pyelonephritis. Conclusions: Cystenium II for acute cystitis or exacerbation of chronic cystitis and ASB in pregnant women improves treatment success and also maintains the effect.

Aim. Study of somatic and obstetric and gynecologic morbidity of women of the Kyrgyz Republic after Cesarean section. Methods. Retrospective cohort study was conducted in 2016 in Kyrgyz state medical institute of retraining and advanced training. Three regions of the Kyrgyz Republic were selected: Bishkek, Jalal-Abad and Issyk-Kul regions. 908 pregnant women after abdominal delivery were chosen as the subject of the study and divided into three groups: group 1 (Bishkek) - 305 pregnant women, group 2 (Jalal-Abad region) - 300 females, group 3 (Issyk-Kul region) - 303 females. The age was 15 to 49 years. The incidence of gynecologic and extragenital pathology and complications during previous pregnancies were studied. Results. Gynecologic pathology in past medical history was revealed in 15.8% of females, while women from group 1 are statistically significantly more likely to have gynecologic diseases than women from group 3. Females from group 2 had gynecologic pathology more rarely. In the structure of gynecologic incidence, sexually transmitted infections take the first place, cervical ectopy takes the second place and uterine fibroids - the third place. Extragenital pathology was detected in 38.2% of pregnant women. In its structure the first ranked place is taken by urinary tract diseases (12.3%), the second one - by infectious and parasitic diseases (11.6%), and the third place - by cardiovascular diseases (3.2%). Pathological course of pregnancy was also more frequent in group 1 than in group 2; there was no significant difference with group 3. Spontaneous abortion interrupted previous pregnancy in 19.8% of women, 5% had premature births, significantly more frequently in group 1, as well as preeclampsia. Conclusion. The most unfavorable region is the city of Bishkek, female residents of Jalal-Abad region are less susceptible to diseases; in general, gynecologic pathology was revealed in 15.8% of females, extragenital pathology - in 38.2% of pregnant women; pathological course of pregnancy was statistically more frequent in group 1 than in group 2, without significant difference with group 3.

The mean Hb levels in group 1, group 2, and group 3· were 12.00±1.68g/dl, 10.06±1.J4g/dl and 10.96±1.19g/dl respectively. The mean Serum ferritin level of group 1 was 67.00±88.38ng/ml, group 2, 52.48±52.47ng/ml and group 3, 51.26±48.70ng/ml. The mean Serum iron in group 1, 2 and 3 were 46.72±16.41 g/dl, 79.59±63.24 g/dl and 83.35±53.04 g/dl respectively. In group 1, 2 and 3 the mean results. ( g/dl) of TIBC were 295.58 ± 109.53, 324.06 ± 178.00 and 319.88 ± 92.95 and % T.S (%) were 18.78 ± 11.77,26.59 ± 19.40 and 17.97 ± 10.87 percent respectively. The mean total protein was group 1,6.83±l1.77g/dl, group 2,6.39±0.70g/dl and group 3, 6.39 ±0.98 g/dl while the mean albumin (g/dl) in group 1, 2 and 3 were 4.84±0.47, 4.13±0.28 and 4.14±0.29 respectively. The mean values of globulin (g/dl) were 1.98 ± 0.91, 2.29 ± 0.87 and 1.89 ± 0.90 in groups 1, 2 and 3 respectively. As gestational age increased; serum ferritin, total protein, and albumin levels decreased while serum" iron and TIBC increased. The differences in the mean results between the groups were statistically significant (p<0.05) while % T.S and globulin levels when compared showed no significant difference (p>0.05). Iron status showed no statistical difference with increasing parity (p>0.05). However, from this study iron deficiency anaemia was most prevalent in second trimester; hence iron status estimation should be an integral part of routine antenatal care test during second trimester of each pregnancy for proper assessment and management of iron deficiency anaemia in pregnancy.

AbstractUndiagnosed thyroid disease is a common problem with significant public health implications. This is especially true during pregnancy, when the health of both the mother and the developing child can be adversely affected by abnormal maternal thyroid function. Measurement of serum thyroid stimulating hormone (TSH) and thyroid peroxidase antibodies (TPO-Ab) are two common ways to assess maternal thyroid status. The objective of our study was to determine the prevalence of abnormal TSH and TPO-Ab tests in a population of pregnant women in the Samara region of the Russian Federation. Serum samples were obtained from 1588 pregnant women as part of their routine antenatal care. TSH and TPO-Ab were measured, and trimester-specific reference values for TSH (2.5–97.5 percentiles) were calculated using TPO-Ab-negative women. TSH results outside these ranges were considered abnormal; TPO-Ab levels outside the manufacturer's reference range (>12IU/mL) were considered abnormal. Overall, the prevalence of abnormal results was 6.3% for TSH and 10.7% for TPO-Ab. High TSH (>97.5 trimester-specific percentile) and TPO-Ab-positive results were most common in the first trimester (5.7% and 13.8%, respectively). TSH levels were associated with gestational age and TPO-Ab status, and with maternal age in TPO-Ab-negative women. TPO-Ab status was associated with both maternal and gestational age. Women with TSH >2.5mIU/L had a significantly increased risk of being TPO-Ab-positive, and this risk increased with age. Based on our data, we conclude that abnormal TSH and TPO-Ab are common in pregnant women of the Samara region. Given the association of thyroid dysfunction to adverse pregnancy outcomes, screening of this population for abnormal thyroid function should be considered.

Abstract 4364 Background We have reported in abstract P-Th-374 in a 2011 Kyoto ISTH Congress that an increased level of D-dimer in combination with umbilical artery systolic diastolic (UASD) ratio can be used as a timing to start with prophylactic anticoagulants In women with pregnancy failure, regardles of the antibody antiphospholipids (APAs) level. The question is: Are there any differences of a serial D-dimer level if is compared to the APAs level?. Methods. A retrospective Cohort study was conducted on a total sampling subjects of pregnancy women who visited two hospitals in Jakarta, Indonesia, at a periode of January 2009 – December 2010. Serial D-dimer using chromogenic assay method (cut off normal level < 500 ng/ml) was tested during antenatal and post partum period. The data were analysed to compare a mean D-dimer with the level of APAs (ACA IgG/IgM, AntiB2GP1 IgG/IgM) tested using ELISA method Results Of 83 pregnant women,19 women with high level of APAs (group 1) showed a mean D-dimer level as follows: Trimester I: 892.15 ± 785.15 ng/ml, trimester II: 782.59 ± 440.53 ng/ml, trimester III:1282.62 ± 601.22 ng/ml, post partum 1367.45 ± 581.19 ng/ml; 31 women with normal APAs (group 2) showed: Trimester I: 666.23 ± 396.24 ng/ml, trimester II: 896.66 ± 396.24 ng/ml, trimester II: 896.66 ± 496.32 ng/ml, trimester III: 1313.45 ± 850.20 ng/ml, post partum: 1991.75 ± 1388.70 ng/ml; 33 women with no data of APAs (group 3) showed: Trimester I: 568.47 ± 482.70 ng/ml, trimester 2: 797.95 ± 934.59 ng/ml, trimester III: 966.89 ± 862.10 ng/ml, post partum: 1078.50 ± 836.29 ng/ml Conclusion Either in group 1, 2, and 3 mean D-dimer tend to increase from trimester I to trimester II and from trimester II to trimester III, except in group 1 from trimester I to trimester II of pregnancy. Meanwhile, all groups showed a higher mean D-dimer post partum compared to antenatal period. Disclosures: No relevant conflicts of interest to declare.
