Nivolumab has promising efficacy for treating various advanced malignant tumors, although it has been reported to induce a wide range of autoimmune adverse effects. We herein report the case of a patient with metastatic lung adenocarcinoma who developed adrenal insufficiency after 12 cycles of nivolumab treatment. Endocrine test results supported a diagnosis of isolated adrenocorticotropic hormone deficiency due to hypophysitis, and replacement therapy using hydrocortisone has been successful. Although hypophysitis is a rare immune-related adverse event that is associated with nivolumab therapy, clinical awareness is essential, as this condition can be life-threatening and requires prompt treatment.

Purpose: Congenital isolated adrenocorticotropic hormone deficiency (CIAD) is an autosomal recessive disorder. This study identifies novel TBX19 variants for CIAD patients, explores its possible effect mechanism at the structural, functional and protein levels, and guides clinicians better understand the condition.
Methods: The clinical characteristics of three CIAD children were summarized.

Central adrenal insufficiency (CAI) occurs due to a pituitary gland disorder (secondary AI) or hypothalamic dysfunction (tertiary AI). It is a potentially life-threatening condition that has many congenital and acquired causes. Adrenocorticotropic hormone deficiency may be isolated or more commonly it can be accompanied by other pituitary hormone deficiencies or midline defects.

Background: To investigate the clinical phenotype, genetic characteristics, and prognosis of isolated adrenocorticotropic hormone deficiency in a newborn (IAD, OMIM 201400) caused by mutation of the gene.
Case Presentation: The clinical features, diagnosis, treatment, and prognosis of a newborn with IAD admitted to our hospital were retrospectively analyzed. The patient and his parents were also examined by whole exome sequencing.

Article Synopsis
- Deficient Anterior pituitary with common Variable Immune Deficiency (DAVID) syndrome is caused by heterozygous mutations leading to adrenocorticotropic hormone deficiency and immune system issues.
- Researchers created pituitary organoids from edited human stem cells to study how specific genetic mutations affect pituitary development and found that these mutations significantly reduced the number of hormone-producing cells called corticotrophs.
- The study identified changes in gene expression related to pituitary development and suggested that the observed mutations have a direct impact on endocrine function, classifying them as pathogenic for pituitary development.

Objective Immune checkpoint inhibitor-associated hypopituitarism (ICI-HP) is a rare immune-related adverse event (irAE) of ICIs. This study aimed to identify characteristic pituitary findings on magnetic resonance imaging (MRI) in ICI-HP. Methods This study is a single-center, retrospective, observational study.
