Endocr Pract 2021 Jan 17;27(1):34-37. Epub 2020 Nov 17.

Department of Pathology, Hadassah-Hebrew University Medical Center, Jerusalem, Israel.

Objective: Treatment with immune-checkpoint inhibitors often results in endocrine immune-related adverse events (irAEs), affecting the pituitary, thyroid, adrenal, and parathyroid glands and pancreas. The mechanism underlying the endocrine irAEs has not been fully elucidated, and it remains unclear why endocrine organs are so commonly affected. In the present study, we evaluated immunostaining patterns of programmed death-ligand 1 (PD-L1) in normal endocrine tissues to determine whether increased expression may explain the predilection of endocrinopathies in patients treated with programmed cell death-1 inhibitors.

Maxim S Petrov

Eur J Endocrinol 2021 Apr;184(4):R137-R149

School of Medicine, University of Auckland, Auckland, New Zealand.

While most people with diabetes have type 2 disease, a non-negligible minority develops a secondary diabetes. Post-pancreatitis diabetes mellitus (PPDM) is an exemplar secondary diabetes that represents a sequela of pancreatitis - the most common disease of the exocrine pancreas. Although this type of diabetes has been known as a clinical entity since the late 19th century, early 21st century high-quality epidemiological, clinical, and translational studies from around the world have amassed a sizeable body of knowledge that have led to a renewed understanding of PPDM.
