Objective:To investigate the predictive value of thyroid hormone sensitivity indicators for adverse pregnancy outcomes in pregnant women with gestational diabetes mellitus (GDM) complicated by hypothyroidism.Methods:A cross-sectional study was conducted to retrospectively analyze the clinical data of 80 pregnant women with GDM complicated by hypothyroidism who were admitted to the Department of Obstetrics, Second Affiliated Hospital of Shaanxi University of Chinese Medicine from February 2022 to February 2024. The patients were divided into two groups: the adverse outcome group ( n = 48) and the normal outcome group ( n = 32) based on the occurrence of adverse pregnancy outcomes. Logistic regression analysis was conducted to identify the risk factors for adverse pregnancy outcomes in these women. Additionally, receiver operating characteristic curve analysis was performed to evaluate the predictive value of thyroid hormone sensitivity indicators for adverse pregnancy outcomes. Results:In the adverse outcome group, the proportion of women with a pre-pregnancy body mass index ≥ 24 kg/m2, triglyceride level, activated partial thromboplastin time, fibrinogen level, thyroid-stimulating hormone level, and thyroid-stimulating hormone index were 58.33% (28/48), (5.77 ± 0.25) mmol/L, (31.79 ± 2.68) seconds, (4.39 ± 0.37) g/L, (5.05 ± 1.07) mU/L, and (3.15 ± 0.24), respectively, which were significantly higher than those in the normal outcome group ( χ2 = 4.41, t = -3.56, -3.23, -2.61, -4.17, -9.15, all P < 0.05). Conversely, the levels of free thyroxine, free triiodothyronine, thyrotroph T4 resistance index, and thyroid feedback quantile index in the adverse outcome group were (9.32 ± 1.04) pmol/L, (3.17 ± 0.42) pmol/L, (33.09 ± 4.26), and (0.19 ± 0.07), respectively, which were all significantly lower than those in the normal outcome group ( t = 4.44, 3.51, 4.31, 2.21, all P < 0.05). Logistic regression analysis revealed that pre-pregnancy body mass index [ OR = 2.673, 95% CI(1.057,6.761)], triglyceride level [ OR = 25.623, 95% CI(3.208,204.673)], activated partial thromboplastin time [ OR = 1.365, 95% CI(1.106,1.685)], fibrinogen level [ OR = 3.111, 95% CI(1.257,7.701)], thyroid-stimulating hormone level [ OR = 2.969, 95% CI(1.613,5.465)], free thyroxine level [ OR = 0.441, 95% CI(0.280,0.695)], free triiodothyronine level [ OR = 0.172, 95% CI(0.057,0.516)], thyroid-stimulating hormone index [ OR = 6.298, 95% CI(1.099, 36.094)], thyrotroph T4 resistance index [ OR = 0.799, 95% CI(0.704,0.907)], and thyroid feedback quantile index [ OR = 0.057, 95% CI(0.168,0.478)] were all factors that influence adverse pregnancy outcomes in pregnant women with GDM complicated by hypothyroidism (all P < 0.05). The area under the curve for predicting adverse pregnancy outcomes using the combined thyroid hormone sensitivity indicators was 0.809 [95% CI (0.704, 0.915), P < 0.001], with a sensitivity of 0.896, specificity of 0.687, and a maximum Youden index of 0.583. Conclusions:The thyroid hormone sensitivity indicators have a certain predictive value for adverse pregnancy outcomes in pregnant women with GDM complicated by hypothyroidism. These indicators can provide important reference for clinical prediction and intervention of adverse pregnancy outcomes in this patient population.

Background:
In acute and chronic renal inflammatory diseases, the activation of inflammatory cells is involved in the defect of erythropoietin (EPO) production. Ras guanine nucleotide-releasing protein-4 (RasGRP4) promotes renal inflammatory injury in type 2 diabetes mellitus (T2DM). Our study aimed to investigate the role and mechanism of RasGRP4 in the production of renal EPO in diabetes.
Methods:
The degree of tissue injury was observed by pathological staining. Inflammatory cell infiltration was analyzed by immunohistochemical staining. Serum EPO levels were detected by enzyme-linked immunosorbent assay, and EPO production and renal interstitial fibrosis were analyzed by immunofluorescence. Quantitative real-time polymerase chain reaction and Western blotting were used to detect the expression of key inflammatory factors and the activation of signaling pathways. In vitro, the interaction between peripheral blood mononuclear cells (PBMCs) and C3H10T1/2 cells was investigated via cell coculture experiments.
Results:
RasGRP4 decreased the expression of hypoxia-inducible factor 2-alpha (HIF2A) via the ubiquitination–proteasome degradation pathway and promoted myofibroblastic transformation by activating critical inflammatory pathways, consequently reducing the production of EPO in T2DM mice.
Conclusion
RasGRP4 participates in the production of renal EPO in diabetic mice by affecting the secretion of proinflammatory cytokines in PBMCs, degrading HIF2A, and promoting the myofibroblastic transformation of C3H10T1/2 cells.
