Screening for autoimmune thyroid disorders after spontaneous abortion is cost-saving and it improves the subsequent pregnancy rate.

ABSTRACT: BACKGROUND: Hypothyroidism and/or autoimmune thyroid disorders (AITD) may contribute to spontaneous abortions (SpA). Cost-effectiveness analyses of thyroid screening in women after SpA are lacking. Our aim was to evaluate the cost-effectiveness of screening for AITD and/or hypothyroidism and their treatment in women after SpA with regard to their reproductive health. METHODS: We performed a cross-sectional non-randomized study with follow-up in 2008-2011 in the settings of Departments of Endocrinology and Obstetrics/Gynecology of a university hospital. We enrolled 258 women after SpA before the 12th gestational week and followed them for a median of 3 years. At enrollment, serum concentrations of thyroid stimulatory hormone (TSH), antibodies to thyroid peroxidase (TPOAb) and free thyroxine (FT4) were measured and thyroid ultrasound performed. Women with overt hypothyroidism were treated with levothyroxine (n?=?45; 61.6%) and women with subclinical hypothyroidism or euthyroid AITD were treated (n?=?28; 38.4%) or left untreated (n?=?38; 14.7%). Euthyroid women without signs of AITD served as controls (n?=?147; 57.0%). RESULTS: Of the 38 untreated women with AITD and/or subclinical hypothyroidism, 8 (21.1%) reported secondary infertility as compared to 16/147 (10.9%) controls and 3/73 (4.1%) treated women (p?=?0.021). Treatment was associated with an increased rate of successfully completed subsequent pregnancies (increment of 6 newborns/100 women) and a savings of €19,539/100 women. Total costs per successfully completed pregnancy were €1,189 in controls, €1,564 in the treated, and €2,488 in the untreated women. CONCLUSIONS: Screening for thyroid disorders in women after SpA and treatment with levothyroxine is cost-saving and it improves the subsequent pregnancy rate.

Project description:BackgroundThe risk of relapse of depression or the diagnosis of some other psychiatric disorders during pregnancy necessitates the use of antidepressants despite possible adverse effects. Whether such use increases the risk of spontaneous abortion is still being debated. We evaluated the risk of spontaneous abortion in relation to the use of antidepressants during pregnancy.MethodsUsing a nested case-control study design, we obtained data from the Quebec Pregnancy Registry for 5124 women who had a clinically detected spontaneous abortion. For each case, we randomly selected 10 controls from the remaining women in the registry who were matched by the case's index date (date of spontaneous abortion) and gestational age at the time of spontaneous abortion. Use of antidepressants was defined by filled prescriptions and was compared with nonuse. We also studied the classes, types and doses of antidepressants.ResultsA total of 284 (5.5%) of the women who had a spontaneous abortion had at least one prescription for an antidepressant filled during the pregnancy, as compared with 1401 (2.7%) of the matched controls (odds ratio [OR] 2.09, 95% confidence interval [CI] 1.83-2.38). After adjustment for potential confounders, we found that the use of antidepressants during pregnancy was associated with an increased risk of spontaneous abortion (OR 1.68, 95%CI 1.38-2.06). Stratified analyses showed that use of selective serotonin reuptake inhibitors alone (OR 1.61, 95% CI 1.28-2.04), serotonin-norepinephrine reuptake inhibitors alone (OR 2.11, 95% CI 1.34-3.30) and combined use of antidepressants from different classes (OR 3.51, 95% CI 2.20-5.61) were associated with an increased risk of spontaneous abortion. When we looked at antidepressant use by type versus no use, paroxetine use alone (OR 1.75, 95% CI 1.31-2.34) and venlafaxine use alone (OR 2.11, 95% CI 1.34-3.30) were associated with an increased risk of spontaneous abortion.InterpretationThe use of antidepressants, especially paroxetine, venlafaxine or the combined use of different classes of antidepressants, during pregnancy was associated with an increased risk of spontaneous abortion.

Project description:BackgroundTraditionally the gold-standard technique for the treatment of spontaneous abortion has been uterine evacuation by aspiration curettage. However, many studies have proposed medical treatment with misoprostol as an alternative to the conventional surgical treatment. The aim of this study was to apply cost minimization methods to compare the cost and effectiveness of the use of vaginal misoprostol as a medical treatment for first trimester spontaneous abortion with those of evacuation curettage as a surgical treatment.Methodology/principal findingsWe present a longitudinal, prospective and quasi-experimental research study including a total of 547 patients diagnosed with first-trimester spontaneous abortion, in the period from January 2013 to December 2015. Patients were offered medical treatment with 800 mg vaginal misoprostol or evacuation curettage. Patients treated with misoprostol were followed-up at 7 days and a transvaginal ultrasound was performed to confirm the success of the treatment. If it failed, a second dose of 800 mg of vaginal misoprostol was prescribed and a new control ultrasound was performed. In case of failure of medical treatment after the second dose of misoprostol, evacuation curettage was indicated. The effectiveness of each of the treatment options was calculated using a decision tree. The cost minimization study was carried out by weighting each cost according to the effectiveness of each branch of the treatment. Of the 547 patients who participated in the study, 348 (64%) chose medical treatment and 199 (36%) chose surgical treatment. The overall effectiveness of medical treatment was 81% (283/348) and surgical treatment of 100%. The estimated final cost for medical treatment was € 461.92 compared to € 2038.72 for surgical treatment, which represents an estimated average saving per patient of € 1576.8.Conclusions/significanceMedical treatment with misoprostol is a cheaper alternative to surgery: in the Spanish Public Healthcare System, it is five times more inexpensive than curettage. Given its success rates higher than 80%, mild side effects, controllable with additional medication and the high degree of overall satisfaction, it should be prioritized over the evacuation curettage in patients who meet the treatment criteria.
