OBJECTIVE

This study determined the incidence of perioperative complications associated with routine preoperative glucocorticoid use in patients undergoing pituitary surgery with normal preoperative hypothalamo-pituitary-adrenal axis (HPA axis).

From 2011-2021 retrospective chart review, 243 patients undergoing pituitary surgery with normal preoperative HPA axis were analyzed into 2 groups: 1) with preoperative steroids and 2) without preoperative steroids.  Development of postoperative complications was subsequently evaluated.

Incidence of primary composite postoperative complications of in-hospital mortality, postoperative infection and postoperative diabetes insipidus (DI) was significantly increased among those who had preoperative steroids compared to those without (58.33% versus 33.33%, p-value 0.004)  with an adjusted odds ratio of 2.90 (CI 1.29 to 6.53, p-value 0.010). Among the components of the composite outcome, post-operative DI was statistically higher among those who were given preoperative steroids (52.45% versus 28.21%, p-value 0.006) with an adjusted OR of 3.31 (CI 1.43 to 7.67, p-value 0.005). The incidence of postoperative adrenal insufficiency was similar between the 2 groups (20.15% with steroids versus 8.70% without steroids, p-value 0.258).

Among patients with normal preoperative HPA axis, the routine use of preoperative steroids is associated with an increased risk of composite postoperative complications (in-hospital mortality, postoperative infection and postoperative DI). Steroid-sparing protocol is not associated with an increased risk of postoperative AI. The findings will encourage more rational use of steroids and minimize preventable complications.

BACKGROUND: Inflammation plays a critical role in severe cerebral venous thrombosis (CVT) pathogenesis, but the benefits of anti-inflammatory therapies remain unclear. This study aimed to investigate the association between steroid therapy combined with anticoagulation and the prognosis of acute/subacute severe CVT patients. METHODS: A prospective cohort study enrolled patients with acute/subacute severe CVT at Xuanwu Hospital (July 2020-January 2024). Patients were allocated into steroid and non-steroid groups based on the treatment they received. Functional outcomes (modified Rankin scale [mRS]) were evaluated at admission, discharge, and 6 months after discharge. Serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), cerebrospinal fluid (CSF) IL-6, and intracranial pressure were measured at admission and discharge in the steroid group. Fundoscopic Frisén grades were assessed at admission and 6 months after discharge. Univariate and multivariate logistic regression were used to evaluat associations between steroid use and favorable outcomes (mRS ≤2) at the 6-month follow-up. Paired tests assessed changes in hs-CRP and other variables before and after treatment, and Spearman's correlations were used to analyze relationships between these changes and functional improvements. RESULTS: A total of 107 and 58 patients in the steroid and non-steroid groups, respectively, were included in the analysis. Compared with the non-steroid group, the steroid group had a higher likelihood of achieving an mRS score of 0-2 (93.5% vs . 82.5%, odds ratio [OR] = 2.98, P  = 0.037) at the 6-month follow-up. After adjusting for confounding factors, the result remained consistent. Pulsed steroid therapy did not increase mortality during hospitalization or follow-up, nor did it lead to severe steroid-related complications (all P  >0.05). Patients in the steroid group showed a significant reduction in serum hs-CRP, IL-6, CSF IL-6, and intracranial pressure at discharge compared to at admission, as well as a significant reduction in the fundoscopic Frisén grade at the 6-month follow-up compare to at admission (all P  <0.001). A reduction in serum inflammatory marker levels during hospitalization positively correlated with improvements in functional outcomes ( P  <0.05). CONCLUSION: Short-term steroid use may be an effective and safe adjuvant therapy for acute/subacute severe CVT when used alongside standard anticoagulant treatments, which are likely due to suppression of the inflammatory response. However, these findings require further validation in randomized controlled trials. TRAIL REGISTRATION ClinicalTrials.gov , NCT05990894.

This study identified 8 members including NjBIN2 of the GSK3 family in Nardostachys jatamansi by bioinformatics analysis. Moreover, the phylogenetic tree revealed that the GKS3 family members of N. jatamansi had a close relationship with those of Arabidopsis. RT-qPCR results showed that NjBIN2 presented a tissue-specific expression pattern with the highest expression in roots, suggesting that NjBIN2 played a role in root growth and development. In addition, the application of epibrassinolide or the brassinosteroid(BR) synthesis inhibitor(brassinazole) altered the expression pattern of NjBIN2 and influenced the photomorphogenesis(cotyledon opening) and root development of N. jatamansi, which provided direct evidence about the functions of NjBIN2. In conclusion, this study highlights the roles of BIN2 in regulating the growth and development of N. jatamansi by analyzing the expression pattern and biological function of NjBIN2. It not only enriches the understanding about the regulatory mechanism of the growth and development of N. jatamansi but also provides a theoretical basis and potential gene targets for molecular breeding of N. jatamansi with improved quality in the future.

The steroid constituents in the 75% ethanol extract of Cyanotis arachnoidea and their anti-HSV-1 activities in vitro were investigated in this study. The ethyl acetate fraction of the extract was isolated and purified using silica gel, ODS, Sephadex LH-20 column chromatography, and semi-preparative HPLC. Structural identification was conducted based on spectroscopic data. Ten steroid compounds were isolated and identified, namely makisterone A 3-acetate(1), makisterone A 2-acetate(2), makisterone A(3), ajugasterone C 2-acetate(4), ajugasterone C(5), 20-hydroxyecdysone 2-acetate(6), 20-hydroxyecdysone 3-acetate(7), podecdysone C(8), rubrosterone(9), and poststerone(10). Compounds 1 and 2 are new steroid compounds. The anti-HSV-1 activities of compounds 1-10 were evaluated using the CPE inhibition method. Vero cells were used in the experiment, with acyclovir as the positive control. The results showed that compounds 9 and 10 showed anti-HSV-1 activity, with EC_(50) values of 83.11 and 103.62 μg·mL~(-1), respectively.

Steroids are a class of medicines with important physiological and pharmacological effects. In pharmaceutical industry, steroidal intermediates are mainly prepared through Mycobacteria transformation, and then modified chemically or enzymatically into advanced steroidal compounds. Compared with the "diosgenin-dienolone" route, Mycobacteria transformation has the advantages of abundant raw materials, cost-effective, short reaction route, high yield and environmental friendliness. Based on genomics and metabolomics, the key enzymes in the phytosterol degradation pathway of Mycobacteria and their catalytic mechanisms are further revealed, which makes it possible for Mycobacteria to be used as chassis cells. This review summarizes the progress in the discovery of steroid-converting enzymes from different species, the modification of Mycobacteria genes and the overexpression of heterologous genes, and the optimization and modification of Mycobacteria as chassis cells.

In recent years, reports of adverse reactions related to traditional Chinese medicine(TCM) have been on the rise, especially some traditionally considered "non-toxic" TCM(such as Dictamni Cortex). This has aroused the concern of scholars. This study aims to explore the metabolomic mechanism underlying the difference in liver injury induced by dictamnine between males and females through the experiment on 4-week-old mice. The results showed that the serum biochemical indexes of liver function and organ coefficients were significantly increased by dictamnine(P<0.05), and hepatic alveolar steatosis was mainly observed in female mice. However, no histopathological changes were observed in the male mice. Furthermore, a total of 48 differential metabolites(such as tryptophan, corticosterone, and indole) related to the difference in liver injury between males and females were screened out by untargeted metabolomics and multivariate statistical analysis. According to the receiver operating characteristic(ROC) curve, 14 metabolites were highly correlated with the difference. Finally, pathway enrichment analysis indicated that disorders of metabolic pathways, such as tryptophan metabolism, steroid hormone biosynthesis, and ferroptosis(linoleic acid metabolism and arachidonic acid metabolism), may be the potential mechanism of the difference. Liver injury induced by dictamnine is significantly different between males and females, which may be caused by the disorders of tryptophan metabolism, steroid hormone biosynthesis, and ferroptosis pathways.

Background: There is a dearth of data on Filipino patients with autoimmune hepatitis (AIH). We aimed to describe the demographic and clinical profiles of patients with AIH and to characterize clinical outcomes and treatment responses. Methods: A retrospective cohort study involving patients from two tertiary centers diagnosed with AIH from January 1, 2007, to December 31, 2019, was included. Disease remission was defined as the normalization of ALT levels, while failure was defined as an increase in ALT levels over baseline or clinical deterioration. Results: A total of 48 patients were identified between 2007 to 2019. The median age at presentation was 51 (27-79 yrs.). Liver cirrhosis was already present in 37.5% (27.1% decompensated) on diagnosis. Aside from a higher histologic activity index in females (p=0.047), there were no gender-specific differences. Disease remission was achieved in 41.9% of patients at 6 months, while only 9.3% failed. At the final disposition, remission rates had slightly increased to 58%, but failure rates had risen to 12%. Treatment responses at both 6 and 12 months and MELD and Child-Pugh class influenced treatment responses at final disposition. Median overall survival was 102 weeks and was influenced by the presence of liver dysfunction and 12 months and final treatment responses. Conclusion Autoimmune hepatitis remains an important cause of morbidity and mortality. The results of the study highlight the need for immunosuppressive therapy to induce early remission for a higher likelihood of subsequent biochemical remission to reduce the risk of liver-related mortality.

Objective: To investigate the clinical efficacy of fecal microbiota transplantation (FMT) for treating steroid-refractory gastrointestinal acute graft-versus-host disease (GI-aGVHD) . Methods: This analysis included 29 patients with hematology who developed steroid-refractory GI-aGVHD after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in Huaian Hospital Affiliated to Xuzhou Medical University from March 2017 to March 2022. Among them, 19 patients underwent FMT treatment (the FMT group) and 10 patients did not (the control group). The efficacy and safety of FMT were assessed, as well as the changes in intestinal microbiota abundance, lymphocyte subpopulation ratio, peripheral blood inflammatory cytokines, and GVHD biomarkers before and after FMT treatment. Results: ① Complete remission of clinical symptoms after FMT was achieved by 13 (68.4%) patients and 2 (20.0%) controls, with a statistically significant difference (P<0.05). Intestinal microbiota diversity increased and gradually recovered to normal levels after FMT and FMT-related infections did not occur. ②The proportion of CD3(+) and CD8(+) cells in the FMT group after treatment decreased compared with the control group, and the ratio of CD4(+), regulatory T cells (Treg), and CD4(+)/CD8(+) cells increased (all P< 0.05). The interleukin (IL) -6 concentration in the FMT group was lower than that in the control group [4.15 (1.91-5.71) ng/L vs 6.82 (2.40-8.91) ng/L, P=0.040], and the IL-10 concentration in the FMT group was higher than that in the control group [12.11 (5.69-20.36) ng/L vs 7.51 (4.10-9.58) ng/L, P=0.024]. Islet-derived protein 3α (REG3α) was significantly increased in patients with GI-aGVHD, and the REG3α level in the FMT group was lower than that in the control group after treatment [30.70 (10.50-105.00) μg/L vs 74.35 (33.50-139.50) μg/L, P=0.021]. Conclusion: FMT is a safe and effective method for the treatment of steroid-refractory GI-aGVHD by restoring intestinal microbiota diversity, regulating inflammatory cytokines, and upregulating Treg cells.
