SGLT-2i associated diabetic ketoacidosis in the setting of cardiogenic shock.

Diabetic ketoacidosis (DKA) is a life-threatening complication of diabetes mellitus. Sodium-glucose co-transport inhibitors (SGLT-2i), a treatment for type 2 diabetes, have demonstrated a survival benefit in patients with heart failure with reduced ejection fraction (HFrEF). Many patients with HFrEF have been started on SGLT-2i and sometimes transitioned off insulin due to improved glycaemic control. SGLT-2i have demonstrated an association with DKA. Here, we present a case of simultaneous cardiogenic shock and DKA in the setting of recent transition from insulin to an SGLT-2i. DKA in conjunction with decompensated heart failure is a combination that will likely occur more frequently as SGLT-2i use becomes more widespread in patients with HFrEF, and its identification and management require special considerations. Volume status, potassium management and recognition of DKA in these patients must be approached differently than in other cases of DKA.

Effects of exercise, metformin and their combination on glucose metabolism in individuals with abnormal glycaemic control: a systematic review and network meta-analysis.

OBJECTIVE: To compare the efficacy of exercise, metformin and their combination on glucose metabolism in individuals with abnormal glycaemic control. DESIGN: Systematic review and network meta-analysis. DATA SOURCES: Embase, Web of Science, PubMed/MEDLINE and SPORTDiscus. ELIGIBILITY CRITERIA: Randomised controlled trials involving exercise, metformin or their combined treatments in individuals with prediabetes or type 2 diabetes mellitus (T2DM) were included. Outcomes included haemoglobin A1c (HbA1c), 2-hour glucose during oral glucose tolerance test, fasting glucose, fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR). RESULTS: 407 articles with 410 randomised controlled trials (n=33 802) were included. In prediabetes, the exercise showed greater efficacy than metformin on HbA1c levels (mean difference -0.16%, 95% CI (-0.23 to -0.09) vs -0.10%, 95% CI (-0.21 to 0.02)), 2-hour glucose (-0.68 mmol/L, 95% CI (-0.97 to -0.39) vs 0.01 mmol/L, 95% CI (-0.38 to 0.41)) and HOMA-IR (-0.54, 95% CI (-0.71 to -0.36) vs -0.23, 95% CI (-0.55 to 0.10)), while the efficacy on fasting glucose was comparable (-0.26 mmol/L, 95% CI (-0.32 to -0.19) vs -0.33 mmol/L, 95% CI (-0.45 to -0.21)). In T2DM, metformin was more efficacious than exercise on HbA1c (-0.88%, 95% CI (-1.07 to -0.69) vs -0.48%, 95% CI (-0.58 to -0.38)), 2-hour glucose (-2.55 mmol/L, 95% CI (-3.24 to -1.86) vs -0.97 mmol/L, 95% CI (-1.52 to -0.42)) and fasting glucose (-1.52 mmol/L, 95% CI (-1.73 to -1.31) vs -0.85 mmol/L, 95% CI (-0.96 to -0.74)); exercise+metformin also showed greater efficacy in improving HbA1c (-1.23%, 95% CI (-2.41 to -0.05)) and fasting glucose (-2.02 mmol/L, 95% CI (-3.31 to -0.74)) than each treatment alone. However, the efficacies were modified by exercise modality and metformin dosage. CONCLUSION: Exercise, metformin and their combination are efficacious in improving glucose metabolism in both prediabetes and T2DM. The efficacy of exercise appears to be superior to metformin in prediabetes, but metformin appears to be superior to exercise in patients with T2DM. PROSPERO REGISTRATION NUMBER: CRD42023400622.

Refractory amiodarone-induced thyrotoxicosis requiring adjunctive cholestyramine treatment.

Amiodarone is an antiarrhythmic drug which may be associated with thyroid dysfunction. Type I amiodarone-induced thyrotoxicosis (AIT) is treated with thionamides and type II AIT is treated with glucocorticoids. Combined therapy is used in mixed or indeterminate forms. When medical treatment is unsuccessful, radioiodine ablation or thyroidectomy is considered. This report reviews a case of AIT refractory to conventional treatment. Despite high doses of methimazole and prednisone, the patient remained clinically and biochemically thyrotoxic. Cholestyramine, a bile salt sequestrant, was used as an off-label adjunctive treatment resulting in significant improvement and achievement of euthyroidism that may also be in part due to the expected natural timeline of recovery from AIT after several months. The patient subsequently trended towards hypothyroidism with symptomatic weight gain and cold intolerance for which he was initiated on levothyroxine.

Expanding the repertoire of ceDAF-12 ligands for modulation of the steroid endocrine system in C. elegans.

Steroid hormones are essential for the biological processes of eukaryotic organisms. The steroid endocrine system of C. elegans, which includes dafachronic acids (DA) and the nuclear receptor ceDAF-12, provides a simple model for exploring the role of steroid hormone signaling pathways in animals. In this study, we show for the first time the feasibility of designing synthetic steroids that can modulate different physiological processes, such as development, reproduction and ageing, in relation to ceDAF-12. Our results not only confirm the conclusions derived from genetic studies linking these processes but also provide new chemical tools to selectively manipulate them, as we found that different compounds produce different phenotypic results. The structures of these compounds are much more diverse than those of endogenous hormones and analogues previously described by other researchers, allowing further development of the chemical modulation of the steroid endocrine system in C. elegans and related nematodes.

Lipid apheresis in the management of severe hypertriglyceridaemia in an adolescent girl with global developmental delay.

Hypertriglyceridaemia-induced acute pancreatitis (HTG-AP) remains one of the common metabolic causes of acute pancreatitis in the paediatric population and the third most common cause after alcohol and gallstones in the adult population. We report a case of an early adolescent girl with global developmental delay and moderate cognitive impairment of unknown aetiology who presented with recurrent acute pancreatitis and uncompensated hypovolaemic shock. She was found to have serum triglyceride level of 7877 mg/dL (reference range<150 mg/dL) and hyperglycaemia with ketosis (no prior history of diabetes mellitus) that was successfully treated with lipid apheresis. This sometimes is an early modality for treatment in adults; however, it remains a last resort in children, used only for severe cases. A brief literature review on severe HTG-AP and its management is also provided.

Mechanisms of Abnormal Lipid Metabolism in the Pathogenesis of Disease.

Lipid metabolism is a critical component in preserving homeostasis and health, and lipids are significant chemicals involved in energy metabolism in living things. With the growing interest in lipid metabolism in recent years, an increasing number of studies have demonstrated the close relationship between abnormalities in lipid metabolism and the development of numerous human diseases, including cancer, cardiovascular, neurological, and endocrine system diseases. Thus, understanding how aberrant lipid metabolism contributes to the development of related diseases and how it works offers a theoretical foundation for treating and preventing related human diseases as well as new avenues for the targeted treatment of related diseases. Therefore, we discuss the processes of aberrant lipid metabolism in various human diseases in this review, including diseases of the cardiovascular system, neurodegenerative diseases, endocrine system diseases (such as obesity and type 2 diabetes mellitus), and other diseases including cancer.

Wharton's jelly stem cells delivered via a curcumin-loaded nanofibrous wound dressings improved diabetic wound healing via upregulating VEGF and IGF genes: An in vitro and in vivo study.

Diabetic wounds pose an enduring clinical hurdle, marked by delayed recovery, persistent inflammation, and an elevated susceptibility to infections. Conventional treatment approaches often fall short of delivering optimal outcomes, prompting the exploration of innovative methods to enhance the healing process. Electrospun wound dressings offer superior healing, controlled drug release, enhanced cell proliferation, biocompatibility, high surface area, and antimicrobial properties. In the current study, polycaprolactone/gelatin-based nanofibrous wound dressings were developed for the delivery of Wharton's jelly stem cells and curcumin into the diabetic wounds bed. Curcumin was loaded into the polycaprolactone/gelatin solution and electrospun to produce curcumin-loaded scaffolds. In vitro experiments including scanning electron microscopy, cell viability assay, release assay, hemocompatibility assay, cell proliferation assay, and antibacterial assay were utilized to characterize the delivery system. Then, curcumin-loaded scaffolds were seeded with 30,000 Wharton's jelly stem cells and implanted into a rat model of diabetic wounds. Study showed that the scaffolds containing both Wharton's jelly stem cells and curcumin significantly improved diabetic wound closure (86.32 3.88% at the end of 14th day), augmented collagen deposition, and improved epithelial tissue formation. Gene expression studies showed that VEGF and IGF genes were significantly upregulated by the co-delivery system. Our developed system may have augmented diabetic wound healing via upregulating pro-healing genes.

Mechanism of Action and Risk Prediction of Adiponectin in Cardiovascular Diseases.

Being one of the pivotal adipocytokines, adiponectin binds to various receptors and exerts diverse biological functions, encompassing anti-fibrosis, anti-atherosclerosis, anti-ischemia-reperfusion, regulation of inflammation, and modulation of glucose and lipid metabolism. Alterations in adiponectin levels are observed in patients afflicted with diverse cardiovascular diseases. This paper comprehensively reviews the impact of adiponectin on the pathogenesis and progression of cardiovascular diseases, elucidating the underlying cellular and molecular mechanisms along with the associated cell signaling pathways. Furthermore, it deliberates on the diagnostic and predictive efficacy of adiponectin as a protein marker for cardiovascular diseases. Additionally, it outlines methods for manipulating adiponectin levels in vivo. A thorough understanding of these interconnections can potentially inform clinical strategies for the prevention and management of cardiovascular diseases.

The profile of blood microbiome in new-onset type 1 diabetes children.

Blood microbiome signatures in patients with type 1 diabetes (T1D) remain unclear. We profile blood microbiome using 16S rRNA gene sequencing in 77 controls and 64 children with new-onset T1D, and compared it with the gut and oral microbiomes. The blood microbiome of patients with T1D is characterized by increased diversity and perturbed microbial features, with a significant increase in potentially pathogenic bacteria compared with controls. Thirty-six representative genera of blood microbiome were identified by random forest analysis, providing strong discriminatory power for T1D with an AUC of 0.82. PICRUSt analysis suggested that bacteria capable of inducing inflammation were more likely to enter the bloodstream in T1D. The overlap of the gut and oral microbiome with the blood microbiome implied potential translocation of bacteria from the gut and oral cavity to the bloodstream. Our study raised the necessity of further mechanistic investigations into the roles of blood microbiome in T1D.

Hypothalamic-pituitary-ovarian axis suppression is common among women during US Army Basic Combat Training.

OBJECTIVE: Less than half of servicewomen report loss of menses during initial military training. However, self-reported menstrual status may not accurately reflect hypothalamic-pituitary-ovarian (HPO) axis suppression and may underestimate reproductive health consequences of military training. Our aim was to characterise HPO axis function during US Army Basic Combat Training (BCT) in non-hormonal contraceptive-using women and explore potential contributors to HPO axis suppression. METHODS: In this 10-week prospective observational study, we enrolled multi-ethnic women entering BCT. Trainees provided daily first-morning voided urine, and weekly blood samples during BCT. Urinary luteinising hormone, follicle stimulating hormone, and metabolites of estradiol and progesterone were measured by chemiluminescent assays (Siemens Centaur XP) to determine hormone patterns and luteal activity. We measured body composition, via dual-energy X-ray absorptiometry, at the beginning and end of BCT. RESULTS: Trainees (n=55) were young (mean (95% CI): 22 (22, 23) years) with average body mass index (23.9 (23.1, 24.7) kg/m2). Most trainees (78%) reported regular menstrual cycles before BCT. During BCT, 23 (42%) trainees reported regular menses. However, only seven trainees (12.5%) had menstrual cycles with evidence of luteal activity (ELA) (ie, presumed ovulation), all with shortened luteal phases. 41 trainees (75%) showed no ELA (NELA), and 7 (12.5%) were categorised as indeterminant. Overall, women gained body mass and lean mass, but lost fat mass during BCT. Changes in body mass and composition appear unrelated to luteal activity. CONCLUSIONS: Our findings reveal profound HPO axis suppression with NELA in the majority of women during BCT. This HPO axis suppression occurs among women who report normal menstrual cycles.

Assessing the Risks of Pesticide Exposure: Implications for Endocrine Disruption and Male Fertility.

Pesticides serve as essential tools in agriculture and public health, aiding in pest control and disease management. However, their widespread use has prompted concerns regarding their adverse effects on humans and animals. This review offers a comprehensive examination of the toxicity profile of pesticides, focusing on their detrimental impacts on the nervous, hepatic, cardiac, and pulmonary systems, and their impact on reproductive functions. Additionally, it discusses how pesticides mimic hormones, thereby inducing dysfunction in the endocrine system. Pesticides disrupt the endocrine system, leading to neurological impairments, hepatocellular abnormalities, cardiac dysfunction, and respiratory issues. Furthermore, they also exert adverse effects on reproductive organs, disrupting hormone levels and causing reproductive dysfunction. Mechanistically, pesticides interfere with neurotransmitter function, enzyme activity, and hormone regulation. This review highlights the effects of pesticides on male reproduction, particularly sperm capacitation, the process wherein ejaculated sperm undergo physiological changes within the female reproductive tract, acquiring the ability to fertilize an oocyte. Pesticides have been reported to inhibit the morphological changes crucial for sperm capacitation, resulting in poor sperm capacitation and eventual male infertility. Understanding the toxic effects of pesticides is crucial for mitigating their impact on human and animal health, and in guiding future research endeavors.

Effects of selective serotonin reuptake inhibitors on endocrine system (Review).

Selective serotonin reuptake inhibitors (SSRIs) are typically prescribed for treating major depressive disorder (MDD) due to their high efficacy. These drugs function by inhibiting the reuptake of serotonin [also termed 5-hydroxytryptamine (5-HT)], which raises the levels of 5-HT in the synaptic cleft, leading to prolonged activation of postsynaptic 5-HT receptors. Despite the therapeutic benefits of SSRIs, this mechanism of action also disturbs the neuroendocrine response. Hypothalamic-pituitary-adrenal (HPA) axis activity is strongly linked to both MDD and the response to antidepressants, owing to the intricate interplay within the serotonergic system, which regulates feeding, water intake, sexual drive, reproduction and circadian rhythms. The aim of the present review was to provide up-to-date evidence for the proposed effects of SSRIs, such as fluoxetine, citalopram, escitalopram, paroxetine, sertraline and fluvoxamine, on the endocrine system. For this purpose, the literature related to the effects of SSRIs on the endocrine system was searched using the PubMed database. According to the available literature, SSRIs may have an adverse effect on glucose metabolism, sexual function and fertility by dysregulating the function of the HPA axis, pancreas and gonads. Therefore, considering that SSRIs are often prescribed for extended periods, it is crucial to monitor the patient closely with particular attention to the function of the endocrine system.

Postoperative Hyponatremia After Endoscopic Endonasal Resection of Pituitary Adenomas: Historical Complication Rates and Risk Factors.

BACKGROUND: Hyponatremia is a common complication following endoscopic endonasal resection (EER) of pituitary adenomas. We report a single-center, multisurgeon study detailing baseline clinical data, outcomes, and factors associated with postoperative hyponatremia. METHODS: This was a retrospective cohort study of patients undergoing EER for pituitary adenoma at Tufts Medical Center. Most procedures were performed by the senior author (C.B.H.). Cases were included if at least 1 postoperative sodium value was available and pathology confirmed pituitary adenoma. Hyponatremia was defined as a postoperative sodium level <135 mEq/L. RESULTS: A total of 272 patients underwent 310 EER procedures that met the study inclusion criteria. The mean patient age was 53.3 years, and mean tumor size was 18.8 mm. Postoperative hyponatremia occurred in 12.6% of cases, with 3.6% developing hyponatremia prior to discharge. Lower preoperative sodium level was associated with an increased risk of developing any postoperative hyponatremia. Older age, prolactinoma pathology, and use of selective serotonin reuptake inhibitors were associated with moderate to severe hyponatremia (≤129 mEq/L), and lower preoperative sodium was associated with mild hyponatremia (130-134 mEq/L). Hyponatremia-related readmissions within 30 days occurred in 3.9% of patients. Both African-American race and postoperative hyponatremia were associated with an increased risk of 30-day readmission. The mean nadir sodium for hyponatremic patients was 129.9 mEq/L. Growth hormone-secreting pathology was associated with lower postoperative nadir sodium, whereas higher preoperative sodium was associated with higher postoperative nadir sodium. CONCLUSIONS: Hyponatremia is a common postoperative complication of EER for pituitary lesions that can cause significant morbidity, increased readmissions, and increased healthcare costs.

Disease types and pathogenic mechanisms induced by PM2.5 in five human systems: An analysis using omics and human disease databases.

Atmospheric fine particulate matter (PM2.5) can harm various systems in the human body. Due to limitations in the current understanding of epidemiology and toxicology, the disease types and pathogenic mechanisms induced by PM2.5 in various human systems remain unclear. In this study, the disease types induced by PM2.5 in the respiratory, circulatory, endocrine, and female and male urogenital systems have been investigated and the pathogenic mechanisms identified at molecular level. The results reveal that PM2.5 is highly likely to induce pulmonary emphysema, reperfusion injury, malignant thyroid neoplasm, ovarian endometriosis, and nephritis in each of the above systems respectively. The most important co-existing gene, cellular component, biological process, molecular function, and pathway in the five systems targeted by PM2.5 are Fos proto-oncogene (FOS), extracellular matrix, urogenital system development, extracellular matrix structural constituent conferring tensile strength, and ferroptosis respectively. Differentially expressed genes that are significantly and uniquely targeted by PM2.5 in each system are BTG2 (respiratory), BIRC5 (circulatory), NFE2L2 (endocrine), TBK1 (female urogenital) and STAT1 (male urogenital). Important disease-related cellular components, biological processes, and molecular functions are specifically induced by PM2.5. For example, response to wounding, blood vessel morphogenesis, body morphogenesis, negative regulation of response to endoplasmic reticulum stress, and response to type I interferon are the top uniquely existing biological processes in each system respectively. PM2.5 mainly acts on key disease-related pathways such as the PD-L1 expression and PD-1 checkpoint pathway in cancer (respiratory), cell cycle (circulatory), apoptosis (endocrine), antigen processing and presentation (female urogenital), and neuroactive ligand-receptor interaction (male urogenital). This study provides a novel analysis strategy for elucidating PM2.5-related disease types and is an important supplement to epidemiological investigation. It clarifies the risks of PM2.5 exposure, elucidates the pathogenic mechanisms, and provides scientific support for promoting the precise prevention and treatment of PM2.5-related diseases.

Exploring the pathogenesis and treatment of PSD from the perspective of gut microbiota.

Post-stroke depression (PSD) is a psychological disease that can occur following a stroke and is associated with serious consequences. Research on the pathogenesis and treatment of PSD is still in the infancy stage. Patients with PSD often exhibit gastrointestinal symptoms; therefore the role of gut microbiota in the pathophysiology and potential treatment effects of PSD has become a hot topic of research. In this review, describe the research on the pathogenesis and therapy of PSD. We also describe how the gut microbiota influences neurotransmitters, the endocrine system, energy metabolism, and the immune system. It was proposed that the gut microbiota is involved in the pathogenesis and treatment of PSD through the regulation of neurotransmitter levels, vagal signaling, hypothalamic-pituitary-adrenal axis activation and inhibition, hormone secretion and release, in addition to immunity and inflammation.

Pembrolizumab autoimmune related diabetes: Moving forward, keep learning.

Immune checkpoint inhibitors (and more specifically programmed cell death 1/programmed cell death ligand 1 inhibitors as Pembrolizumab) initiated a revolution in the field of melanoma and have now expanded to several tumor subtypes and in increasingly broader clinical contexts, including the adjuvant and neoadjuvant setting, with potentially curable patients and prolonged survival. The side effects related to these drugs include a wide spectrum of manifestations, with endocrinological adverse events being some of the most frequent. Pembrolizumab-induced type 1 diabetes mellitus is an infrequent but potentially serious and not clearly reversible side effect that possesses characteristic clinical features and has high morbidity and mortality, with a chronic impact on quality of life. The etiopathogenesis of this phenomenom needs to be further investigated and a collaborative effort through the involvement of oncologists and other medical specialists is necessary for the correct identification and management of patients at risk.

Mechanisms of Male Reproductive Sterility Triggered by Dysbiosis of Intestinal Microorganisms.

The intestinal microbiota, comprised of bacteria, archaea, and phages, inhabits the gastrointestinal tract of the organism. Male reproductive sterility is currently a prominent topic in medical research. Increasing research suggests that gut microbiota dysbiosis can result in various reproductive health problems. This article specifically investigates the impact of gut microbiota dysbiosis on male reproductive infertility development. Gut microbiota imbalances can disrupt the immune system and immune cell metabolism, affecting testicular growth and sperm production. This dysfunction can compromise the levels of hormones produced and secreted by the endocrine glands, affecting male reproductive health. Furthermore, imbalance of the gut microbiota can disrupt the gut-brain-reproductive axis, resulting in male reproductive infertility. This article explores how the imbalance of the gut microbiota impacts male reproductive infertility through immune regulation, endocrine regulation, and interactions of the gut-brain-reproductive axis, concluding with recommendations for prevention and treatment.

Can the analysis of chromatin texture and nuclear fractal dimensions serve as effective means to distinguish non-invasive follicular thyroid neoplasm with papillary-like nuclear features from other malignancies with follicular pattern in the thyroid?: a study.

OBJECTIVE: Thyroid carcinoma ranks as the 9th most prevalent global cancer, accounting for 586,202 cases and 43,636 deaths in 2020. Computerized image analysis, utilizing artificial intelligence algorithms, emerges as a potential tool for tumor evaluation. AIM: This study aims to assess and compare chromatin textural characteristics and nuclear dimensions in follicular neoplasms through gray-level co-occurrence matrix (GLCM), fractal, and morphometric analysis. METHOD: A retrospective cross-sectional study involving 115 thyroid malignancies, specifically 49 papillary thyroid carcinomas with follicular morphology, was conducted from July 2021 to July 2023. Ethical approval was obtained, and histopathological examination, along with image analysis, was performed using ImageJ software. RESULTS: A statistically significant difference was observed in contrast (2.426 (1.774-3.412) vs 2.664 (1.963-3.610), p = .002), correlation (1.202 (1.071-1.298) vs 0.892 (0.833-0.946), p = .01), and ASM (0.071 (0.090-0.131) vs 0.044 (0.019-0.102), p = .036) between NIFTP and IFVPTC. However, morphometric parameters did not yield statistically significant differences among histological variants. CONCLUSION: Computerized image analysis, though promising in subtype discrimination, requires further refinement and integration with traditional diagnostic parameters. The study suggests potential applications in scenarios where conventional histopathological assessment faces limitations due to limited tissue availability. Despite limitations such as a small sample size and a retrospective design, the findings contribute to understanding thyroid carcinoma characteristics and underscore the need for comprehensive evaluations integrating various diagnostic modalities.

Effects of chronic exposure to a high fat diet, nutritive or non-nutritive sweeteners on hypothalamic-pituitary-adrenal (HPA) and -gonadal (HPG) axes of male Sprague-Dawley rats.

PURPOSE: Diet-related factors are of great significance in the regulation of hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonad (HPG) axes. In this study, we aimed to investigate the effects of chronic exposure to a high fat diet (HFD), fructose or sucralose on the endocrine functions. METHODS: Male, Sprague-Dawley rats received a normal chow diet, HFD, 10% fructose or 0.02% sucralose for 10 weeks. Behavioral changes were assessed by open field (OFT) and elevated plus-maze (EPM) tests at week 8. H&E staining was used to observe pathological changes in adrenal cortex, testis and perirenal adipose tissue. Serum hormone concentrations were quantified via enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of genes along the HPA and HPG axes were determined using real-time PCR. RESULTS: All types of dietary interventions increased body weight and disturbed metabolic homeostasis, with anxiogenic phenotype in behavioral tests and damage to cell morphology of adrenal cortex and testis being observed. Along the HPA axis, significantly increased corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and corticosterone (CORT) concentrations were observed in the HFD or 0.02% sucralose group. For HPG axis, gonadotropin-releasing hormone (GnRH) and estradiol (E2) concentrations were significantly increased in all dietary intervention groups, while decreased concentrations of follicle-stimulating hormone (FSH) and testosterone (T) were also detected. Moreover, transcriptional profiles of genes involved in the synthesis of hormones and corresponding hormone receptors were significantly altered. CONCLUSION: Long-term consumption of HFD, fructose or sucralose manifested deleterious effects on endocrine system and resulted in the dysregulation of HPA and HPG axes.

Immune checkpoint inhibitor-induced hypophysitis with transient ACTH-dependent hypercortisolism.

A woman in her 70s with metastatic melanoma presenting with refractory hypokalaemia on combined immune checkpoint inhibitors, nivolumab-ipilimumab, was diagnosed with adrenocorticotropic hormone (ACTH)-dependent hypercortisolism 11 weeks following the initiation of her immunotherapy. Investigations also demonstrated central hypothyroidism and hypogonadotropic hypogonadism. She underwent imaging studies of her abdomen and brain which revealed normal adrenal glands and pituitary, respectively. She was started on levothyroxine replacement and had close pituitary function monitoring. Two weeks later, her cortisol and ACTH levels started to trend down. She finally developed secondary adrenal insufficiency and was started on hydrocortisone replacement 4 weeks thereafter.This report highlights a case of immunotherapy-related hypophysitis with well-documented transient central hypercortisolism followed, within weeks, by profound secondary adrenal insufficiency. Healthcare professionals should remain vigilant in monitoring laboratory progression in these patients. Early recognition of the phase of hypercortisolism and its likely rapid transformation into secondary adrenal insufficiency can facilitate timely hormonal replacement and prevent complications.
