ABSTRACT
Oxytocin can regulate immunological activity directly or indirectly; however, immunological functions and mechanisms of oxytocin actions under chronic stress like cesarean delivery (CD) are poorly understood. Our study found that abnormal oxytocin production and secretion in CD rats caused atrophy of thymic tissues. Neurotoxin kainic acid microinjected into the dorsolateral supraoptic nucleus in male rats selectively reduced hypothalamic oxytocin levels, increased corticotrophin-releasing hormone and plasma interleukin-1ß while reducing plasma oxytocin, thyroxine and testosterone levels and causing atrophy of immune tissues. Thus, plasma oxytocin is essential for immunological homeostasis, which involves oxytocin facilitation of thyroid hormone and sex steroid secretion.
ABSTRACT
Imbalances in dopamine activity significantly contribute to the pathophysiology of several neuropsychiatric disorders, including addiction, ADHD, schizophrenia, impulse control disorders, and Parkinson's Disease. Neuro(active)steroids, comprising endogenous steroids that finely modulate neuronal activity, are considered crucial regulators of brain function and behavior, with implications in various physiological processes and pathological conditions. Specifically, subclasses of Neuro(active)steroids belonging to the 5α reductase pathway are prominently involved in brain disorders characterized by dopaminergic signaling imbalances. This review highlights the neuromodulatory effects of Neuro(active)steroids on the dopamine system and related aberrant behavioral phenotypes. We critically appraise the role of pregnenolone, progesterone, and allopregnanolone on dopamine signaling. Additionally, we discuss the impact of pharmacological interventions targeting 5α reductase activity in neuropsychiatric conditions characterized by excessive activation of the dopaminergic system, ranging from psychotic (endo)phenotypes and motor complications to decision-making problems and addiction.
ABSTRACT
The clinical course and treatment of hypercalcemia from a granulomatous disease in the setting of an infectious etiology, namely disseminated coccidioidomycosis, remains incompletely understood. The mechanism and treatment of hypercalcemia have been documented in most granulomatous disorders, with sarcoidosis being the most well-understood so far. We discuss a case of a patient with a recent diagnosis of disseminated coccidioidomycosis who presented with hypercalcemia despite adequate infection control. The treatment course involved combinatorial-calcitonin, low-dose bisphosphonates, and corticosteroids, which led to a favorable outcome.
ABSTRACT
Chronic Lymphocytic Inflammation with Pontine Perivascular Enhancement Responsive to Steroids (CLIPPERS) is a rare central nervous system inflammatory condition usually presenting with a range of symptoms, including ataxia, diplopia, dysarthria, seizures, and headaches. We present a unique case of a 22-year-old woman exhibiting headache as the sole symptom. Imaging and biopsy confirmed the diagnosis, and initial steroid treatment provided relief, though it relapsed on tapering. Long-term management with low-dose steroids and mycophenolate mofetil achieved remission. This case highlights the importance of recognizing atypical presentations of CLIPPERS, emphasizing the need for prompt diagnosis and appropriate treatment plans to improve patient outcomes. Further research is necessary to enhance our understanding and management of CLIPPERS.
ABSTRACT
Anti-melanoma differentiation-associated gene 5 (anti-MDA5) dermatomyositis (DM) is a subset of amyopathic myositis and is associated with unique cutaneous manifestations and rapidly progressive interstitial lung disease (RP-ILD). A rare complication associated with high mortality is the occurrence of pneumomediastinum. We present a case of a 58-year-old female with anti-MDA5 DM-associated interstitial lung disease (ILD) complicated by pneumomediastinum. Treatment with pulse dose steroids and intravenous cyclophosphamide led to clinical improvement and resolution of the pneumomediastinum. Our case emphasizes the recognition of ILD-associated pneumomediastinum in patients with anti-MDA5 DM. Swift diagnosis and aggressive treatment are crucial due to the associated high mortality.
ABSTRACT
Background and Aims: Immune checkpoint inhibitor therapy causes numerous immune-related adverse events, including autoimmune pancreatic injury (AIPI), which results in rapid organ atrophy. We profiled the clinico-radiological features, short-term natural history, and response to steroids of AIPI. Methods: We retrospectively reviewed medical records of 229/11,165 (2.1%) adult patients with AIPI. One hundred and ten out of 229 (48%) had abdominal computerized tomography (CT) scan at lipase elevation; data of 110 without pancreatic metastases were analyzed. We analyzed serial CT-based pancreas volumetry data in 48 patients with AIPI (32 with normal CT and 16 with pancreatitis on CT at lipase elevation). We examined impact of steroids on pain and disease course. Results: In AIPI (n = 229), median lipase elevation was 4x upper limit of normal (range: 3-40x). The injury was more often asymptomatic than painful (143/229 (62%) vs 86/229 (38%), P < .000). Majority (83/110 (75%) had normal CT, often in painless vs painful disease: 51/57 (90%) vs 32/53 (60%), P < .001) 25% had interstitial pancreatitis. On serial pancreas volumetry, marked volume (cc) loss occurred 1 year after vs 3 months before lipase elevation in both normal CT (median 81.6 vs 61.3, P = .00) and pancreatitis on CT groups (91.8 vs 60.5, P = .00), ≥20% volume loss occurred in 47% vs 73%, respectively (P = .08). Steroids, when used did not mitigate pain, biochemical relapse, pancreas volume loss or 1-year diabetes incidence (7.2%). Conclusion: Autoimmune pancreatic injury (AIPI) is uniquely characterized by painless lipase elevation, normal pancreas on CT and rapid pancreatic volume loss on follow-up. Steroids do not appear to have a role in management.
ABSTRACT
Steroid hormones exhibit potent endocrine disrupting activity and have been shown to disrupt the equilibrium of aquatic ecosystems and pose a threat to public health through their persistent and carcinogenic effects. Pontibacillus chungwhensis HN14, a moderately halophilic bacterium with the capacity to effectively degrade various polycyclic aromatic hydrocarbons and other organic pollutants, was previously isolated. Additionally, the strain HN14 showed strong environmental adaptability under various environmental stress conditions. In this study, the steroid degradation by strain HN14 was studied for the first time. We demonstrated that strain HN14 could degrade estradiol (E2) to maintain the growth of the strain and could convert E2 to estrone. Additionally, the efficient substrate degradation efficiency of P. chungwhensis HN14 under high salinity and high substrate concentration conditions was demonstrated. Furthermore, a 17ß-hydroxysteroid dehydrogenase, 17ß-HSD(HN14), was identified in strain HN14. Comparative analysis reveals that 17ß-HSD(HN14) shares approximately 38% sequence identity with 17ß-HSDx from Rhodococcus sp. P14. In addition, 100 µg of purified 17ß-HSD(HN14) could effectively convert about 40% of 0.25 mM of E2 within 1 h period, with an enzyme activity of 17.5 U/mg, and catalyze the dehydrogenation of E2 and testosterone at the C-17 position. The characterization of purified enzyme properties reveals that 17ß-HSD(HN14) exhibits exceptional structural robustness and enzymatic efficacy even under high salinity conditions of up to 20%. Overall, this study enhances our comprehension of steroid biodegradation in strain HN14 and contributes novel ideas and theoretical underpinnings for advancing bioremediation technologies targeting steroid pollution in high-saline environments.

BACKGROUND AND AIM: Evidence suggests there has been an increase in anabolic-androgenic steroid (AAS) use among women, driven by the evolving landscape of women's participation in sport. However, the extent of use is unknown. This systematic review aimed to estimate the prevalence of women's AAS use. METHOD: We conducted a systematic review of peer-reviewed articles in English, focusing on AAS use among women aged 18 and above. We excluded grey literature and studies that measured doping through some form of analysis (e.g. urine or hair). Searched databases were MEDLINE, CINAHL, PsycINFO, SocINDEX, SPORTDiscus, Embase and Cochrane Library. Titles and abstracts for all articles were screened, followed by full-text assessment and data extraction of included articles by multiple authors for accuracy. The pooled prevalence of lifetime use was determined using a random effects model and the risk of bias was assessed using the Joanna Briggs Institute Prevalence Critical Appraisal Tool. RESULTS: Based on 18 studies, participant numbers averaged 669 per study (median = 189; range = 16 to 7051). The overall pooled AAS use prevalence was 4% (95% confidence interval [CI] = 2-9%) with high heterogeneity overall (I2 = 95%). In the subgroup analysis, AAS use prevalence was 16.8% (95% CI = 11.0-24.9%, I2 = 44%) in the bodybuilder subgroup, 4.4% (95% CI = 1.2-15.1%, I2 = 93%) in athletes/recreational gym user subgroup, and 1.4% (95% CI = 0.4-4.7%, I2 = 96%) in the general population/other subgroup. Meta-regression demonstrated significantly higher AAS use in bodybuilders compared with the other subgroup (P = 0.011). CONCLUSION: Anabolic-androgenic steroid use among women appears to be substantially higher among bodybuilders and athletes/recreational gym users than the general female population.
ABSTRACT
Sex differences are widespread during neurodevelopment and play a role in neuropsychiatric conditions such as autism, which is more prevalent in males than females. In humans, males have been shown to have larger brain volumes than females with development of the hippocampus and amygdala showing prominent sex differences. Mechanistically, sex steroids and sex chromosomes drive these differences in brain development, which seem to peak during prenatal and pubertal stages. Animal models have played a crucial role in understanding sex differences, but the study of human sex differences requires an experimental model that can recapitulate complex genetic traits. To fill this gap, human induced pluripotent stem cell-derived brain organoids are now being used to study how complex genetic traits influence prenatal brain development. For example, brain organoids from individuals with autism and individuals with X chromosome-linked Rett syndrome and fragile X syndrome have revealed prenatal differences in cell proliferation, a measure of brain volume differences, and excitatory-inhibitory imbalances. Brain organoids have also revealed increased neurogenesis of excitatory neurons due to androgens. However, despite growing interest in using brain organoids, several key challenges remain that affect its validity as a model system. In this review, we discuss how sex steroids and the sex chromosomes each contribute to sex differences in brain development. Then, we examine the role of X chromosome inactivation as a factor that drives sex differences. Finally, we discuss the combined challenges of modeling X chromosome inactivation and limitations of brain organoids that need to be taken into consideration when studying sex differences.
Sex differences are a contributing factor in neuropsychiatric conditions such as autism, which is more prevalent in males. Sex differences occur through interactions between sex steroid hormones such as estrogen and testosterone and sex chromosomes (chrX and chrY). Human stem cellderived brain organoids are laboratory models that mimic brain development. For example, in individuals with neurodevelopmental conditions, brain organoids have revealed an imbalance of neuron populations compared with neurotypical individuals. In this review, we discuss sex steroid and sex chromosome influences on brain development and challenges of this model that need to be taken into account when studying sex differences.
ABSTRACT
Introduction: Black ginseng (BG) was processed by "steaming and drying" (generally nine times) repeatedly to produce "rare saponins" and secondary ginsenosides. Both ginseng (GS) and red ginseng (RG) were commonly used in treating heart failure (HF), and the latter was confirmed to be more potent, implying the presence of rare ginsenosides that contribute positively to the treatment of heart failure. Previous research indicated that rare ginsenosides are more abundant in BG than in RG. Consequently, this study aims to investigate the effects of BG and its components on HF to elucidate the active substances and their underlying mechanisms in the treatment of HF. Methods: The effects of BG and its fractions (water-eluted fraction (WEF), total saponin fraction (TSF), and alcohol-eluted fraction (AEF)) on rats with isoproterenol (ISO)-induced HF were explored, and steroids belonging to the hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes were determined quantitatively using the ultra-performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-QqQ-MS/MS) method. In addition, 16S rDNA sequencing was performed on the gut microbiota, followed by GC-MS analysis of short-chain fatty acids (SCFAs), and the biochemical indexes related to energy metabolism and the serum cyclic nucleotide system were also analyzed by ELISA. Results: Based on a thorough evaluation of energy metabolism and the endocrine system, it was observed that the effects of BG components on the hypothalamic-pituitary-thyroid (HPT) and HPA axes were more pronounced. Notably, the treatment efficacy of the low dose of the total saponin fraction (TSFL), water decoction (WD), and high dose of the polysaccharide fraction (PSFH) was superior based on pharmacodynamic indicators such as brain natriuretic peptide (BNP), creatine kinase (CK), and estradiol (E2)/T). Furthermore, the WD and BG components exhibited significant effects on androgens (T and androstenedione (A4)). The TSFL group exerts an anti-inflammatory effect by regulating Lactobacillus/Erysipelotrichales. The WD, PSFH, and TSFL may impact inflammatory cytokines through the gut microbiota (Lactobacillus/Erysipelotrichales) and their metabolites (acetate and butyrate), exerting an anti-inflammatory effect. Discussion: The BG and all its split components demonstrated varying levels of efficacy in alleviating HF, and TSF and PSF exhibited a significant protective effect on HF. The main active components in TSF were revealed to be ginsenosides Rk1, Rk3, 20-(S)-Rg3, and 20-(S)-Rh2 by the H9C2 cell experiment. The decoction of BG and its components exhibited a potent impact on androgen hormones, with an elevation trend. This phenomenon may be attributed to the activation of the eNOS-NO pathway through androgen regulation, thereby contributing to its anti-HF activities. The WD, PSFH, and TSFL may exert anti-inflammatory effects through the intestinal flora (Lactobacillaceae/Erysipelotrichaceae) and its metabolites (acetic acid and butyric acid), which affect the inflammatory factors. The different mechanisms of action of each component of HF also reflect the significance and necessity of the overall role of traditional Chinese medicine (TCM). Our research was the first to report that the E2/T is related to HF and can be used as an indicator to evaluate HF.
ABSTRACT
Complications of Crohn's disease reach far beyond postsurgical leak, infection, and enterocutaneous fistula. Malnutrition, intestinal failure, and recurrent disease all will require ongoing attentions. The management of these patients may further be complicated by the need for chronic immunosuppression. The underlying principles continue to include optimization of nutritional status, and preservation of bowel length when possible. However, there have been several recent advances in both the medical and surgical management of the disease. Understanding the contribution of the mesentery to inflammation, new surgical techniques such as the Kono-S anastomosis and extended mesenteric resection is decreasing the need for repeated resections.

Previous studies have suggested a negative impact of steroids on the efficacy of immune checkpoint inhibitors (ICI), but how this effect is modulated by the dosage and time of administration is yet to be clarified. We have performed a retrospective analysis of 475 patients with advanced solid tumors treated with ICI as monotherapy from 2015 to 2022. Data regarding immune-related adverse events (irAEs) and clinical outcomes were collected. For each patient, the daily steroid dose (in mg/kg of prednisone) was registered until disease progression or death. The impact of cumulative doses on response rates and survival outcomes was analyzed within different periods. The objective response rate (ORR) was significantly lower among patients exposed to steroids within 30 days before the first cycle of ICI (C1) (20.3% vs. 36.7%, p < 0.01) and within the first 90 days of treatment (25.7% vs. 37.7%, p = 0.01). This negative association was confirmed by multivariable analysis. Higher mean steroid doses were observed among non-responders, and cumulative doses were inversely correlated with the disease control rate (DCR) around ICI initiation. Remarkably, poorer outcomes were observed even in patients belonging to the lowest dose quartile compared to the steroid-naïve population. The exposure to steroids after 6 months of ICI was not associated with worse survival outcomes. Our results suggest that the potential impact of steroids on ICI efficacy may be time-dependent, prevailing around ICI initiation, and dose-dependent, with modulation of neutrophil-to-lymphocyte ratio as a possible underlying mechanism.

BACKGROUND: With an ongoing demand for transplantable organs, optimization of donor management protocols, specifically in trauma populations, is important for obtaining a high yield of viable organs per patient. Endocrine management of brain-dead potential organ donors (BPODs) is controversial, leading to heterogeneous clinical management approaches. Previous studies have shown that when levothyroxine was combined with other treatments, including steroids, vasopressin, and insulin, BPODs had better organ recovery and survival outcomes were increased for transplant recipients. AIM: To determine if levothyroxine use in combination with steroids in BPODs increased the number of organs donated in trauma patients. METHODS: A retrospective review of adult BPODs from a single level 1 trauma center over ten years was performed. Exclusion criteria included patients who were not solid organ donors, patients who were not declared brain dead (donation after circulatory death), and patients who did not receive steroids in their hospital course. Levothyroxine and steroid administration, the number of organs donated, the types of organs donated, and demographic information were recorded. Univariate analyses were performed with P < 0.05 considered to be statistically significant. RESULTS: A total of 88 patients met inclusion criteria, 69 (78%) of whom received levothyroxine and steroids (ST/LT group) vs 19 (22%) receiving steroids without levothyroxine (ST group). No differences were observed between the groups for gender, race, pertinent injury factors, age, or other hormone therapies used (P > 0.05). In the ST/LT group, 68.1% (n = 47) donated a high yield (3-5) of organ types per donor compared to 42.1% (n = 8) in the ST group (P = 0.038). There was no difference in the total number of organ types donated between the groups (P = 0.068). CONCLUSION: This study suggests that combining levothyroxine and steroid administration increases high-yield organ donation per donor in BPODs in the trauma patient population. Limitations to this study include the retrospective design and the relatively small number of organ donors who met inclusion criteria. This study is unique in that it mitigates steroid administration as a confounding variable and focuses specifically on the adjunctive use of levothyroxine.
ABSTRACT
Chromatography combined with mass spectrometry is a gold standard technique for steroid measurement, however the type of sample preparation, the dynamic range and reliability of the calibration curve, the chromatographic separation and mass spectrometry settings ultimately determine the success of the method. The steroid biosynthetic pathway is conserved in higher mammals and literature demonstrates that the concentration ranges of different steroid groups are relatively comparable across species. We sought to develop a robust and reliable multi steroid targeted analysis method for blood that would have wide application across higher mammals. The method was developed following bioanalytical method validation guidelines to standards typically applied to human clinical studies, including isotopically labelled internal standards where at all possible. Here we describe the practical approach to a 96-well supported liquid extraction (SLE) method of extraction from plasma (200 µL) using an Extrahera liquid handling robot (Biotage, Sweden), including quality control samples, followed by a comprehensive separation and targeted LC-MS/MS analysis of 18 steroids in plasma (pregnenolone, progesterone, 17α-hydroxyprogesterone, 11-deoxycorticosterone, corticosterone, 11-dehydrocorticosterone, aldosterone, 11-deoxycortisol, 21-deoxycortisol, cortisol, cortisone, androstenedione, testosterone, 5α-dihydrotestosterone, dehydroepiandrosterone, estrone, 17ß-estradiol and estriol). â¢SLE in a 96-well format of up to 74 biological plasma samples, enriched with multiple isotopically labelled internal standards, a 12-point aqueous calibration curve, and 6 serum quality controls, designed to monitor long-term performance of the methodâ¢Chromatographic separation of multiple steroids along the gradient, with ammonium fluoride mobile phase additive to improve sensitivity, followed by electrospray ionisation and constant polarity switchingâ¢Aqueous calibration standards that cover physiologically relevant ranges - high nanomolar glucocorticoids, low nanomolar androgens and picomolar ranges for estrogens and steroid intermediates.
ABSTRACT
Background: Improper use of over-the-counter (OTC) steroid medication has been linked to recalcitrant dermatophytosis. There is proven evidence of HPA axis suppression by the use of long-term oral steroids. This study aims to determine the prevalence and pattern of inappropriate OTC steroid use and its effects on the hypothalamus-pituitary-adrenal (HPA) axis in adults with recalcitrant dermatophytosis. Materials and Methods: This cross-sectional study of 2 months was conducted in a hospital setting and included patients of recalcitrant dermatophytosis with a history of OTC steroid use. Clinico-demographic details and basal serum cortisol levels were recorded in all and analyzed. Result: Of a total of 103 patients, 59.22% (n = 61/103) were males, and the mean duration of steroid abuse was 17.78 months. About 48.54% (n = 50/103), 3.88% (n = 4/103), and 47.57% (n = 49/103) patients reported the use of topical steroids, oral steroids, and both oral and topical steroids, respectively. Among all the topical steroid users (n = 99), clobetasol propionate 48.48% (n = 48/99), while among oral steroid users (n = 53), prednisolone 45.28% (n = 24/53) were the most commonly used agents, respectively. The morning serum cortisol levels (8-9 AM) were found to be decreased in 42.7% (n = 44/103), with a mean value of 44.28 ± 17.34 µg/dL. Conclusion: Improper OTC steroid use in recalcitrant dermatophytosis leads to HPA axis suppression. This highlights the need for intervention from apex health officials.
ABSTRACT
Oral ulcers are one of the most common complaints seen by general practitioners in their offices. Recurrent aphthous stomatitis affects roughly 20% of the general population. When ulcers persist despite conventional treatment, it is crucial to consider systemic diseases such as Behçet's disease to prevent delays in care. Early recognition and appropriate management of underlying conditions are essential for improving patient outcomes and quality of life. We present a case of a 41-year-old Scottish male who came in with complaints of recurrent oral ulcers and oral thrush. Initial treatment by an infectious disease specialist resolved the oral thrush but not the ulcers. Despite further treatment attempts for three years, including biopsy and antiviral therapy, ulcers persisted. Finally, referral to rheumatology led to comprehensive autoimmune testing, revealing positive HLA B51 and a diagnosis of Behçet's disease. Treatment with topical steroids and colchicine yielded significant improvement.
ABSTRACT
Rhegmatogenous retinal detachment (RRD) is an ocular emergency as it is sight-threatening and requires urgent surgical intervention. Ulcerative colitis (UC) is an immune-mediated inflammatory bowel disease that can present with ocular manifestations. The objective of this case report is to share the rare presentation of RRD associated with UC leading to diagnosis and management dilemmas. A 35-year-old man with active UC presented with a right chronic red eye for two months. The best corrected visual acuity (BCVA) was 6/6 in both eyes (OU). On examination, sectoral inferotemporal anterior scleritis (AS) with subclinical inferior RRD with peripheral holes in the lattice at the 6 o'clock position was noted. There was no posterior vitreous detachment. Optical coherence tomography (OCT) delineated the RRD objectively and was non-progressive for nine months. Barricade laser was given, in addition to intravenous methylprednisolone (IVMP), followed by a tapering dose of oral prednisolone and topical dexamethasone 0.1% over three months. Over a year, the scleritis resolved. However, six months later, while still on immunomodulating agents, the inferior RRD progressed on OCT. Segmental scleral buckle, indirect laser retinopexy, and subtenon triamcinolone injection were performed. IVMP 1 g per day was given for three days prior to surgery. Two months later, his BCVA was 6/6, with signs of fluid resorption and normal intraocular pressure. No recurrent AS was seen. Treatment of non-progressive, subclinical RRD patients with UC and active AS can be delayed with regular follow-up. When RRD progressed and there was no AS activity, it was the window of opportunity for the success of scleral buckle and perioperative steroids.
ABSTRACT
BACKGROUND: Granulomatous mastitis (GM) is a benign, chronic, inflammatory disease lacking clear treatment guidelines. The purpose of this American Society of Breast Surgeons (ASBrS) prospective, multisite registry was to characterize the presentation of GM and identify treatment strategies associated with symptom resolution and optimal cosmesis. METHODS: ASBrS members entered data into a registry on patient demographics, treatment, symptoms, and cosmesis over a 1-year period. Initial symptoms were graded as mild, moderate, or severe. The Chi-square test and logistic regression were used to identify factors related to symptom improvement and cosmesis. RESULTS: Overall, 112 patients with a mean age of 36 years were included. More patients were Hispanic (49.1%) and from the Southwest (41.1%), and management included observation (4.5%), medical (70.5%), surgical (5.4%), or combination treatment (19.6%). Immunosuppression was used in 83 patients (74.1%), including 43 patients who received intralesional steroid injections. Patients with severe symptoms were more likely to undergo surgical intervention compared with those with mild or moderate symptoms (21.4% vs. 0% and 7.5%, respectively; p = 0.004). Within 1 year, 85 patients (75.9%) experienced symptom improvement and/or resolution at a median of 3 months. Receipt of immunosuppressive therapy was predictive of improvement or resolution at 1 month (odds ratio 4.22; p = 0.045). One-year physician-assessed cosmesis was excellent or good for 20/35 patients (57.1%) and was not associated with type of treatment or symptom severity. CONCLUSION: Although GM can have a protracted course, the majority of patients in this registry resolved within 1 year, with good cosmetic result. Treatment with immunosuppression appears to be most beneficial, and a symptom-based algorithm may be helpful to guide treatment.
