Only few studies have examined the subsequent important outcomes of maternal glucocorticoid and mineralocorticoid deficiencies during pregnancy upon the fetus and the neonate. Therefore, this systematic review and meta-analysis evaluated the impact of these deficiencies, with data from PubMed/Medline, Cochrane/CENTRAL, and Google Scholar. A total of 31 studies were included for qualitative analysis and 11 for quantitative analysis. Studies examining the prevalence of spontaneous abortion, preterm birth, the occurrence of small for gestational age (SGA) neonates, as well as the neonatal birth weight were included. The systematic review revealed a substantial number of spontaneous abortions, preterm births and SGA neonates in pregnant women with PAI. The meta-analysis showed a mean spontaneous abortion prevalence of 18%, 18% and 17% in women with PAI, AD or CAH, respectively. The mean preterm birth prevalence was 11% when women with AD or CAH were analyzed together, and 13% and 9% in women with AD or CAH, respectively, when these women were analyzed separately. The mean prevalence of SGA neonates was 8% when women with AD or CAH were analyzed together, and 5% and 10% in women with AD or CAH, respectively, when these women were analyzed separately. The mean fetal birth weight was within normalcy in all women with PAI, as well as in women with AD or CAH. In conclusion the executed systematic review of 31 studies followed by a meta-analysis of 11 studies in pregnant women with PAI has shown a greater prevalence of pregnancies with negative outcome (spontaneous abortion, preterm birth) and of negative fetal outcome (SGA) in women with either AD or CAH, as compared to control pregnant women.</p>","PeriodicalId":11572,"journal":{"name":"Endocrine","volume":"20 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Group 1 included type 1 DM patients with satisfactory compensation of carbohydrate metabolism; group 2 consisted of patients with frequent hypoglycemic conditions and pathological glucose variability; group 3 included individuals with prolonged hyperglycemic conditions and maximum HbA1c levels; and group 4 comprised patients with the glycemic profile characterized by all the presented types of dysglycemia (intermittent glycemia).</p><p><strong>Results: </strong>We revealed a negative correlation between serum catalase activity and time of hypoglycemic conditions in patients with type 1 DM based on the CGM results (r_s = -0.47, p < 0.01). In group 4 (intermittent glycemia), patients demonstrated the lowest serum catalase activity and increased serum 3-nitrotyrosine level, while in group 3, women with chronic hyperglycemia (HbA1c 8.4 [8.1; 9.9]%; 68 [65; 85] mmol/mol) had a moderate change in antioxidant defense and oxidative stress parameters. Correlation analysis of ovarian volume, the antral follicle count, and the serum anti-Müllerian hormone level in type 1 DM women with different glycemic profiles established a negative relationship (r_s = -0.82, p < 0.05) between the antral follicle count and glucose variability in group 1, a positive relationship (r_s = 0.68, p < 0.05) between ovarian volume and glucose variability in group 2, and a positive relationship (r_s = 0.88, p < 0.05) between ovarian volume and time of hypoglycemic conditions, which, according to the CGM results, amounted to","PeriodicalId":11572,"journal":{"name":"Endocrine","volume":" ","pages":"1131-1140"},"PeriodicalIF":3.7,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141261570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
