OBJECTIVES
To determine the incidence, presentation, frequency and management of immune checkpoint inhibitors (ICI)-related endocrinopathies in a comprehensive cancer centre in Oman, particularly with programme death 1/programme death-ligand 1 (PD-1/PD-L1) inhibitors.
BACKGROUND
A high number of patients treated with PD-1/PD-L1 inhibitors for the management of solid tumours developed endocrinopathies.
METHODS
This is a retrospective study of patients admitted to Sultan Qaboos Comprehensive Cancer Care and Research Centre (SQCCCRC) from August 2021 to December 2022. All adults diagnosed with solid cancers and have received at least one dose of ICIs were included. Patients with incomplete data were excluded from the analysis. Data regarding the ICI-induced endocrinopathy were collected.
RESULTS
A total of 139 patients were included in the study of which 58% were females. The median age of the cohort was 56 years. The incidence of endocrine-related adverse events was 28%. The mean time for the development of endocrine adverse events after treatment initiation was 4.1 ± 2.8 months. Of the patients who developed toxicity, 90% had hypothyroidism. Ten patients developed hyperthyroidism, two patients were diagnosed with secondary adrenal insufficiency/hypophysitis and one patient developed Type 1 diabetes mellitus (DM). Using univariable logistic regression weight and body mass index (BMI) significantly impacted the development of endocrine immune-related adverse events (irAEs).
CONCLUSIONS
This is the first study from the Sultanate of Oman to assess PD-1/PDL-1 ICI-induced endocrinopathies. The most common endocrine adverse event is thyroid dysfunction, mainly hypothyroidism followed by hyperthyroidism. Hypophysitis, primary adrenal insufficiency and CIADM occur less frequently, but have a more significant effect on the patient's health. The treating physician should be aware of ICI-induced endocrinopathies, screening and treatment. Furthermore, our study showed that patients with a higher BMI have a greater risk of developing irAES. Further studies are needed to establish the predictors of endocrine irAEs.

Acquired thyroid-stimulating hormone, luteinizing hormone, and follicle-stimulating hormone deficiencies with circulating anti-glycoprotein hormones alpha chain-positive cell antibodies.
BACKGROUND
A patient with systemic lupus erythematosus (SLE) suffered from acquired thyroid-stimulating hormone (TSH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) deficiencies. MRI findings revealed a slight atrophy of the pituitary gland. Further, the serum concentration of the covalent alpha subunit (glycoprotein hormones alpha chain [CGA]) in TSH-, LH-, and FSH-positive cells was below the detectable range. Because SLE is an autoimmune disorder, autoimmunity against the pituitary gland was suspected as the cause of pituitary deficiency.
METHODS AND RESULTS
Immunofluorescence analysis showed that the patient's immunoglobulin G recognized CGA-positive cells in the pituitary gland; therefore, autoimmunity against CGA-positive cells may have caused TSH, LH, and FSH deficiencies in this patient. Moreover, cell-specific autoimmunity impairs pituitary hormone levels. Further research is required to clarify whether acquired TSH, LH, and FSH deficiencies are common in patients with SLE or other autoimmune diseases.
CONCLUSION
Our findings highlight a unique case of acquired TSH, LH, and FSH deficiencies caused by circulating anti-CGA-positive cell antibodies, introducing a novel clinical concept of acquired hypopituitarism.

BMC Geriatrics Jun 2024IgG4-related diseases are very uncommon, and its diagnosis and treatment are complicated as it encompasses multiple disciplines.
BACKGROUND
IgG4-related diseases are very uncommon, and its diagnosis and treatment are complicated as it encompasses multiple disciplines.
CASE PRESENTATION
A 77-year-old woman was admitted with a jaw mass and nausea and vomiting. Laboratory tests showed elevated serum IgG4, pituitary MRI suggested thickening of the pituitary stalk, and head and neck CT suggested orbital and mandibular masses. Patients with mandibular mass were diagnosed with Mikulicz's disease with IgG4-related hypophysitis. We found no other evidence of causing thickening of the pituitary stalk. She was given oral prednisolone 30 mg daily, and her nausea and vomiting improved significantly, and the mandibular and ocular masses decreased in size.
CONCLUSION
Mikulicz's disease combined with IgG4-related hypophysitis is a rare case of IgG4-RD in elderly women. IgG4-RD is one of the causes of head and neck exocrine gland mass and pituitary stalk thickening in the elderly.

Autoimmune hypophysitis (AH) is an uncommon condition where there is inflammation of the pituitary gland which leads to hormonal imbalances. It is often associated with autoimmune diseases; however, a case is yet to be reported with an association of AH with seronegative rheumatoid arthritis (RA). We present a case of a 45-year-old female who complained of polyuria/polydipsia and rapid weight gain. An MRI of the head revealed enlargement of the pituitary gland, concerning for AH. Although she was initially treated for diabetes insipidus, she began reporting new complaints of joint pains and morning stiffness. She was clinically diagnosed with seronegative RA and improved with a trial of hydroxychloroquine. A repeat MRI showed improvement in the abnormal pituitary findings, and the patient was closely monitored with a multidisciplinary approach. Diagnosing and managing patients with AH are topics that are still being explored and researched as it is a relatively rare pathology. Consequently, we found the need to discuss the relationship of AH with seronegative RA and delve into the various diagnostic and treatment approaches.

A 78-year-old man complained of subacute general fatigue and anorexia, following diplopia and gait disturbance. He demonstrated wide-based and small-stepped gait without objectively abnormal ocular movements. Brain MRI showed enlargement of the pituitary stalk and gland with uniform contrast enhancement. PET-CT showed FDG uptake in the pituitary gland, mediastinal lymph nodes, and left hilar lymph nodes. Blood investigations revealed panhypopituitarism and high serum IgG4 levels up to 265 mg/dl. Histopathological examination revealed no IgG4-positive cell infiltration in the biopsied mediastinal lymph nodes. However, we suspected IgG4-associated hypophysitis based on the clinical symptoms and MRI findings, which were markedly resolved with steroid. Central masked diabetes insipidus was manifested, but was improved with oral desmopressin. We should pay close attention to the fact that IgG4-related hypophysitis may present with various symptoms regarded as indefinite complaints related to aging or underlying diseases, especially in elderly patients with multimorbidity.

COVID-19 vaccines have resulted in a remarkable reduction in both the morbidity and mortality associated with COVID-19. However, there are reports of endocrine rare clinical conditions linked to COVID-19 vaccination. In this report, we present a case of hypophysitis following COVID-19 vaccination and review the literature on this condition. This case involved a 72-year-old male with type 1 diabetes who experienced symptoms such as vomiting, appetite loss, and headaches following his fifth COVID-19 vaccine dose. He was diagnosed with secondary adrenal insufficiency; subsequent assessment revealed an enlarged pituitary gland. Unlike previous cases, our patient has partial recovery from pituitary insufficiency, and his pituitary function gradually improved over time. Anti-pituitary antibodies (APAs) against corticotrophs, thyrotrophs, gonadotrophs, and folliculo stellate cells (FSCs) were detected in serum samples taken 3 months after onset. Hypophysitis after COVID-19 vaccination is a rare clinical condition, with only eight cases reported by the end of 2023, most occurring after the initial or second vaccination. Symptoms of hypophysitis after COVID-19 vaccination are similar to those of classic pituitary dysfunction. Pituitary insufficiency is persistent, with five of the above eight patients presenting posterior pituitary dysfunction and three patients presenting only anterior pituitary dysfunction. Two of those eight patients had autoimmune diseases. Our case suggests a potential link between acquired immunity, APA production, and pituitary damage. To elucidate the etiology of hypophysitis associated with COVID-19 vaccination, detailed investigation of patients with nonspecific symptoms after vaccination against COVID-19 is necessary.

Review
The early-stage clinical course of anti-pituitary-specific transcription factor-1 hypophysitis diagnosed post-immune checkpoint inhibitor treatment: A case with review of literature.
Anti-pituitary-specific transcription factor-1 (PIT-1) hypophysitis, a paraneoplastic syndrome resulting from an autoimmune response against PIT-1, typically manifests with undetectable levels of growth hormone (GH) and prolactin (PRL), and significantly low levels of serum thyroid-stimulating hormone (TSH) at diagnosis. These hormonal levels are highly specific to this disease and serve as key diagnostic indicators. Herein, we present a detailed clinical course of a 69-year-old male with a history of gastric cancer and lymph node metastases who developed anti-PIT-1 hypophysitis after the initiation of immune checkpoint inhibitor (ICI) therapy, specifically nivolumab, oxaliplatin, and capecitabine. The patient was referred to our department owing to decreased TSH, free triiodothyronine (T3), and free thyroxine (T4) levels after two doses of nivolumab. Initially suspected as central hypothyroidism due to ICI-related hypophysitis, further assessment confirmed the diagnosis of anti-PIT-1 hypophysitis. Notably, GH, PRL, and TSH levels markedly declined, leading to complete deficiencies 2 months after the first nivolumab dose-a pattern consistent with that of previous cases of anti-PIT-1 hypophysitis. Therefore, this report not only presents an atypical subset of ICI-related hypophysitis but also delineates the process of hormone impairment leading to complete deficiencies in anti-PIT-1 hypophysitis. This case highlights the importance of vigilant monitoring for endocrine issues in patients undergoing ICI therapy, given the escalating incidence of immune-related adverse events associated with the extensive use of ICI therapy for various cancers.

Review
OBJECTIVE
Onset and exacerbation of autoimmune, inflammatory or steroid-responsive conditions have been reported following the remission of Cushing syndrome, leading to challenges in distinguishing a new condition versus expected symptomatology following remission. We describe a case of a 42-year-old man presenting with new-onset sarcoidosis diagnosed 12 months following the surgical cure of Cushing syndrome and synthesise existing literature reporting on de novo conditions presenting after Cushing syndrome remission.
METHODS
A scoping review was conducted in Medline, Epub, Ovid and PubMed. Case reports and case series detailing adult patients presenting with new-onset conditions following Cushing syndrome remission were included.
RESULTS
In total, 1641 articles were screened, 138 full-text studies were assessed for eligibility, and 43 studies were included, of which 84 cases (including our case) were identified. Most patients were female (85.7%), and the median reported age was 39.5 years old (IQR = 13). Thyroid diseases were the most commonly reported conditions (48.8%), followed by sarcoidosis (15.5%). Psoriasis, lymphocytic hypophysitis, idiopathic intracranial hypertension, multiple sclerosis, rheumatoid arthritis, lupus and seronegative arthritis were reported in more than one case. The median duration between Cushing remission and de novo condition diagnosis was 4.1 months (IQR = 3.75). Of those patients, 59.5% were receiving corticosteroid therapy at the time of onset.
CONCLUSION
Our scoping review identified several cases of de novo conditions emerging following the remission of Cushing syndrome. They occurred mostly in women and within the year following remission. Clinicians should remain aware that new symptoms, particularly in the first year following the treatment of Cushing syndrome, may be manifestations of a wide range of conditions aside from adrenal insufficiency or glucocorticoid withdrawal syndrome.

BACKGROUND
Immune-checkpoint inhibitors (ICI) have revolutionized cancer treatment by harnessing the immune system but ICI can induce life-threatening immune-related adverse events (irAE) affecting every organ.
METHODS
We extracted irAE from VigiBase, the international pharmacovigilance database, first reported in 2008 until 01/2023 to characterize irAE reporting trends, clinical features, risk factors and outcomes.
FINDINGS
We distinguished 25 types of irAE (n = 50,347cases, single irAE/case in 84.9%). Cases mainly involved anti-PD1 (programmed-death-1) monotherapy (62.4%) in male (61.7%) aged 64.3 ± 12.6 years. After 2020 vs. prior to 2016, proportion of anti-CTLA4 (Cytotoxic-T-Lymphocyte-Antigen-4) monotherapy prescription almost vanished (1.6% vs. 47%, respectively) contrasting with increased use of anti-PDL1 (PD1-ligand) monotherapy (18% vs. 0.9%) and anti-CTLA4+anti-PD(L)1 combination (20% vs. 8.9%). Anti-LAG3 (Lymphocyte-Activation-Gene-3) prescription was limited (<1%) in the studied timeframe. After 2020, over 14 different cancer types were treated vs. almost exclusively melanoma and lung cancers before 2016. Overall, the most reported irAE were skin reactions (22.9%), pneumonitis (18.5%), enterocolitis (14.4%) and thyroiditis (12.1%). ICI-myotoxicities (6.6%) included myositis, myocarditis and myasthenia-gravis like syndrome and were the most overlapping irAE (up to 30% overlap, vs. <3% in general for other inter-irAE overlap). The top factors associated with specific irAE (odds-ratio>5) were presence of thymic cancer for ICI-myotoxicities or hepatitis; presence of melanoma for vitiligo, uveitis or sarcoidosis; specific types of ICI regimen (anti-LAG3 for meningitis, anti-CTLA4 for hypophysitis); and specific reporting regions (eastern Asia for cholangitis). Median time-to-onset ranged from 31 to 273 days, being shortest for myotoxicities and most delayed for skin-bullous auto-immune reactions. Overall fatality was highest for myocarditis = 27.6%, myasthenia = 23.1%, severe cutaneous adverse reactions (SCAR) = 22.1%, myositis = 21.9%, pneumonitis = 21%, and encephalomyelitis = 18%; generally decreasing after 2020, except for myasthenia and SCAR. When reported, irAE recurrence rate after rechallenge was 28.9% (n = 275/951).
INTERPRETATION
This up-to-date comprehensive worldwide pharmacovigilance study defines the spectrum, characteristics, and evolution of irAE reporting summarizing over a decade of use. Multiple risk factors and clinical peculiarities for specific irAE have been identified as signals to guide clinical practice and future research.
