Abstract Objective The changes of microbial community in pregnant women, let alone those of patients with recurrent spontaneous abortion (RSA), remain unclear. We analyzed the differences of gut mircobiota (GM) between RSA patients and pregnant women to find the possible mechanism of RSA. MethodsWe enrolled 30 RSA patients (RSA group) and 30 pregnant women who terminated their pregnancy and did not have a history of spontaneous abortion (NR group) in our hospital from June 2020 to August 2020, and fecal samples were obtained to analyze the GM using 16S rDNA V3–V4 sequencing.ResultsAt the phylum level, we found that there is no significant difference in composition of GM between RSA and NR. But at the genus level, compared with NR, Roseburia significantly decreased (P<0.01), and Ruminococcus significantly increased in RSA patients (P<0.05). Further analysis indicated that Klebsiella (P<0.05) was significantly increased, Prevotella.9 (P<0.05) and Roseburia (P<0.05) were significantly decreased in RSA2 group (BMI>23.9 in RSA). Moreover, Agathobacter (P<0.01) was significantly increased in NR2 group (no delivery in NR). Functional prediction indicated that GM may interfere with RSA through membrane transport, carbohydrate metabolism, amino acid metabolism and other pathways.ConclusionDecreased Roseburia in GM of pregnant women maybe related to RSA. Our results provide the basis for in-depth studies of the composition of gut microbial communities in RSA.

Recurrent miscarriage, defined as loss of two or more consecutive pregnancies, occurs in 1–2% of couples attempting to bear children. The major causes of recurrent pregnancy loss (RPL) based on the literature include parental structural chromosome rearrangement, immunologic factors (i.e. antiphospholipid syndrome), thrombophilic factors (both inherited and acquired), anatomic factors of uterine anomalies, and endocrinologic disorders. Luteal phase defect, polycystic ovarian syndrome (PCOS), diabetes mellitus, thyroid disease and hyperprolactinemia are among the endocrinologic disorders implicated in approximately 17% to 20% of RPL. The prevalence of hypothyroidism in the general population of reproductive age is about 2-3%. The aim of this study is to observe the benefit of screening for hypothyroidism amongst women with recurrent spontaneous abortion early in the first trimester. The study included one hundred and sixty (160) women, in the reproductive age of life, where there ages ranged from 20 – 33 years, and divided into two groups. Study group which included eighty (80), non pregnant women with a history of two or more consecutive spontaneous abortions early in the first trimester, with no living children and control group which included eighty (80), non pregnant women having one or more living children without any history of abortion. Hypothyroidism was noted in ten (10) cases (12.5%) in the study group and noted in two (2) cases (2.5%) in the control group with a statistically significant difference (P < 0.01). The mean levels of TSH in the study group was 22.71  13.13 Iu/ml. Conclusion: Screening for hypothyroidism has clinical significance and would help to reduce miscarriage rate in women with recurrent spontaneous abortion.

Several therapeutic regimens have been proposed for women with recurrent spontaneous abortion (RSA) and antiphospholipid antibodies (APA). Conflicting results have been reported about women with history of RSA, positive APA, and failure of standard therapy. To evaluate the use of intravenous immunoglobulin in RSA patients with APA and history of treatment failure, we initiated a study with standard therapy (aspirin and low-molecular- weight heparin) and intravenous immunoglobulin. We used an enzyme-linked immunosorbent assay (ELISA)test to screen IgG and IgM anticardiolipin antibodies, and a diluted Russel viper venom time assay for the lupus anticoagulant activity. Altogether. 66 pregnant women with positive APAs at the first visit could be included. Patients with hereditable thrainbaghilic factors were excluded. After confirmation of the pregnancy, women received a basis immunization of 0.3 g/kg immunoglobulin in a 4-week cycle until the 28th to 32nd week of gestation. All patients received 100 mg/d aspirin and 3,000 anti-Xa U/d certoparin. Among the 66 pregnant women, 17 were persistently autoantibody positive (25.8%), of whom 11 (16.7%) were ACA positive alone, 2 (3%) were lupus anticoagulant positive, and 4 (6.4%) had both antibody types. A total of 49 patients had positive APAs at the initial test, but were negative for ACA and lupus anticoagulant at the second test administered approximately 5 weeks after the start of therapy. We described this group in our following observation as "antibody negative." Sixteen of the 17 autoantibody-positive patients (94.1 %) were delivered of live infants compared with 40 patients (81.6%) in the antibody-negative group (odds ratio [OR]: 1.2; 95% CI: 0.98 to 1.4). The overall miscarriage rate was 12.1% and the fetal loss rate was 15.2%. Four patients (25%) in the antibody-positive group developed symptoms of preeclampsia and fetal growth retardation compared with four patients (9.8%) in the antibody-negative group. In conclusion. we see a reduction of the fetal loss rate in patients with RSA and positive APA (5.8%) compared with APAnegative (18.4%) women with the same therapy (OR: 0.3; 95% CI: 0.04 to 2.3).
