recurrent pregnancy loss thyroid

IMPORTANCE: Recurrent pregnancy loss (RPL) is one of the most frustrating clinical entities in reproductive medicine requiring not only diagnostic investigation and therapeutic intervention, but also evaluation of the risk for recurrence. OBJECTIVE: The aim of this study was to review and compare the most recently published major guidelines on investigation and management of RPL. EVIDENCE ACQUISITION: A descriptive review of guidelines from the Royal College of Obstetricians and Gynaecologists, the European Society of Human Reproduction and Embryology, the American Society for Reproductive Medicine, the French College of Gynecologists and Obstetricians, and the German, Austrian, and Swiss Society of Gynecology and Obstetrics on RPL was carried out...

BACKGROUND: Many couples experience difficulties to become pregnant or carry a pregnancy to term due to unknown causes. Here we define pre-pregnancy complications as having prior recurrent pregnancy loss, prior late miscarriages, time to pregnancy more than one year, or the use of artificial reproductive technologies. We aim to identify factors associated with pre-pregnancy complications and poor well-being in early pregnancy. METHODS: Online questionnaire data from 5330 unique pregnancies in Sweden were collected from November 2017 - February 2021...

STUDY QUESTION: Does the occurrence of non-visualized pregnancy loss (NVPL) affect future reproductive outcomes in patients with recurrent pregnancy loss (RPL)? SUMMARY ANSWER: The number of previous NVPLs is a significant predictor of subsequent live birth in patients with RPL. WHAT IS KNOWN ALREADY: The number of preceding miscarriages is a strong indicator for future reproductive outcomes. However, NVPL particularly has been sparsely addressed in previous literature...

There has been increasing recognition of the association between various pregnancy complications and development of chronic disease in later life. Pregnancy has come to be regarded as a physiological stress test, as the strain it places on a woman's body may reveal underlying predispositions to disease that would otherwise remain hidden for many years. Despite the increasing body of data, there is a lack of awareness among healthcare providers surrounding these risks. We performed a narrative literature review and have summarized the associations between the common pregnancy complications including gestational hypertension, pre-eclampsia, gestational diabetes, placental abruption, spontaneous preterm birth, stillbirth and miscarriage and subsequent development of chronic disease...

INTRODUCTION: It is documented that a series of autoantibodies can be detected with increased frequency in women with recurrent pregnancy loss (RPL) and they may impact the pregnancy prognosis negatively. It is unknown whether the autoantibodies per se or the basic immune disturbances underlying autoantibody production, are the reason for this association. Our group has previously found that some genetically determined immunological biomarkers are associated with RPL and the same biomarkers are also in various degrees known to predispose to autoantibody production...

STUDY QUESTION: What are the subsequent reproductive outcomes (livebirths, miscarriages or other adverse pregnancy outcomes or no further pregnancy) of women with recurrent miscarriage (RM) attending a dedicated clinic? SUMMARY ANSWER: Of women with RM, 77% had a subsequent pregnancy, and among these pregnancies, the livebirth rate was 63%. WHAT IS KNOWN ALREADY: RM affects ∼1-3% of women of reproductive age. RM has known associations with advanced maternal age, obesity, diabetes, inherited thrombophilias, thyroid dysfunction, endometriosis and parental balanced translocations...

OBJECTIVES: Changes in coagulation indexes, thromboelastogram(TEG) and autoantibodies in patients with recurrent pregnancy loss (RPL) with different number of abortions were analyzed. METHODS: Medical records of 48 patients with recurrent abortion, treated in Quzhou people's Hospital from November 2019 to October 2020, were collected as the observation group. Based on the number of abortions, patients were divided into Group-A (Two abortions, n=21), Group-B (Three abortions, n=16) and group C (Abortion ≥ four times, n=11)...

OBJECTIVE: To investigate preconceptual thyroid peroxidase antibody (TPO-ab) positivity and/or thyroid stimulating hormone (TSH) levels in the upper range of normal as risk factors for recurrent unexplained first-trimester miscarriage. DESIGN: A post-hoc study of a randomized trial, in which acetylsalicylic acid did not affect the risk of a new miscarriage. PATIENTS: Women (n = 483) with at least three unexplained recurrent first-trimester miscarriages investigated at a Swedish secondary referral center...

INTRODUCTION: Thyroid autoimmunity (TAI) is the most common autoimmune disorder. Patients with TAI are usually euthyroid, and the presence of anti-thyroid peroxidase (anti-TPO) in patients with or without thyroid dysfunction is associated with infertility, recurrent embryo implantation failure, and early pregnancy loss. We aimed to investigate the relationship between low ovarian reserve, pregnancy outcomes, and TAI. MATERIAL AND METHODS: This retrospective cohort study was conducted in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) patients between 2010 and 2018...

OBJECTIVES: The purpose of this study was to explore if thyroperoxidase antibody positivity impacts thyroid stimulating hormone levels during pregnancies following the index visit and how live birth rate is impacted when treated subclinical hypothyroidism is treated with levothyroxine or not. STUDY DESIGN: A retrospective chart review of 1443 recurrent pregnancy loss patients from BC Women's Hospital recurrent pregnancy loss clinic was conducted. Thyroid stimulating hormone in pregnancies after the index visit across thyroperoxidase antibody status was analyzed using mixed-effects linear regression...

The thyroid is a gland located in the neck and is important for many processes in the body. Problems with the thyroid gland are common in women of reproductive age. It is essential to have a normal working thyroid gland in order to achieve a successful pregnancy. One of the most common problems with the thyroid is underactivity (known as hypothyroidism). An early, mild form of an underactive thyroid is called subclinical hypothyroidism. Often people with this condition do not have any symptoms. Another common problem is thyroid autoimmunity...

Objective: This study aimed to assess whether the use of levothyroxine was beneficial in pregnant women with subclinical hypothyroidism (SCH) or women who were positive for thyroid peroxidase antibody (TPOAb+ ). Study design: This was a randomized clinical trial involving 1736 populations of pregnant women. Our study was conducted into two groups: normal pregnant group and recurrent pregnancy loss (RPL) pregnant group. Both patients were divided into SCH and TPOAb+ groups, respectively; the patients of four groups were randomized into either the L-T4 treatment or control groups...

Maternal thyroid hormones are critical for the growth and development of a healthy fetus. During pregnancy, maternal thyroid hormone production is increased to meet the demands of fetal growth. The purpose of this review is to provide clinicians with current evidence about possible adverse maternal and fetal effects of hypothyroidism in pregnancy, including the role of hypothyroidism in recurrent pregnancy loss. In addition, clinical presentation, evidence-based screening guidelines, and evidence-based treatments are discussed...

A male infant was born by spontaneous delivery on February 7, 2020, with a gestational age of 40 weeks and a birth weight of 4.1 kg. After birth, the infant presented with appearance of skin loss on the bilateral lower limbs, feet, left wrist, face, and lips. Large areas of skin defects, erosion, and exudation were noted on the extensor side of the bilateral lower limbs and feet, and some skin loss with a small amount of exudation was observed on the left wrist, face, and lips, which was accompanied by dorsal hyperextension of the right foot and oral mucosal ulceration (Figure 1)...

Recurrent pregnancy loss (RPL) affects 1-2 % of women. Allo- and autoimmune disorders are a recognized factor for RPL and poor pregnancy outcomes. There is a link between antiphospholipid syndrome (APS), Hashimoto's thyroiditis or coeliac disease, and pregnancy losses. The prevalence of the HLA-DQ2/DQ8 polymorphism and genetic susceptibility to the development of celiac disease may be higher in women who experience RPL. A total of 95 women who had experienced two or more miscarriages were qualified into the study: 49 women with the HLA-DQ2/DQ8 polymorphism as the study group, and 46 as the control group...

PURPOSE: Does the OPtimization of Thyroid function, Thrombophilia, Immunity, and Uterine Milieu (OPTIMUM) treatment strategy, developed for treating repeated implantation failure (RIF), contribute to improving pregnancy outcomes in patients with a history of recurrent pregnancy loss (RPL)? METHODS: Between 2018 and 2019, women with RPL after two or more clinical pregnancy losses underwent RPL testing. We treated chronic endometritis with antibiotics, high Th1/Th2 cell ratios with vitamin D and/or tacrolimus, overt/subclinical hypothyroidism with levothyroxine, and thrombophilia with low-dose aspirin...

Recurrent pregnancy loss (RPL) is usually characterized as ≥3 miscarriages before 20 weeks of gestation. Patients with RPL may have autoimmune abnormalities or alloimmune problems. Vitamin D has a major function on the mechanism of immunomodulation at the maternal‑fetal interface. However, whether vitamin D can be used as an effective method to treat patients with RPL requires investigation. It has been reported that vitamin D could prevent the occurrence of antiphospholipid syndrome (APS) by reducing the expression levels of anti‑β2 glycoprotein and tissue factor in RPL cases with APS...

Background and objectives: Thyroid autoimmunity (TAI) has been associated with a significantly increased risk of miscarriage in women with recurrent pregnancy loss (RPL). The aim of this study was to determine the prevalence of TAI in women with RPL and compare the clinical characteristics of positive and negative TAI women. Materials and Methods: This is a retrospective cross-sectional study; 203 women with RPL were included. Thyroid profile, anti-thyroid peroxidase (TPO-Ab), and anti-thyroglobulin (TG-Ab) antibodies were measured in all participants...

BACKGROUND: Women with a history of gestational diabetes mellitus are at a substantially increased risk of gestational diabetes mellitus recurrence and type 2 diabetes. Weight gain, particularly increased central adiposity after delivery, is strongly associated with deterioration of pancreatic beta cell compensation for insulin resistance. Weight management after gestational diabetes mellitus could have a significant benefit in these women who are at a high risk of developing type 2 diabetes...

PROBLEM: Antibody-mediated autoimmune diseases, such as autoimmune thyroid diseases (ATD), systemic lupus erythematosus (SLE), and antiphospholipid syndrome (APS), often are associated with recurrent fetal loss. One of the ATD is Hashimoto's thyroiditis which recently showed association with complications of pregnancy with increased levels of circulating autoantibodies reactive with epitopes on thyroid tissue such as thyroid peroxidase (anti-TPO). In retrospective study of sera analyses in patients with Hashimoto's thyroiditis, all patients had mainly elevated circulating anti-TPO autoantibodies...
