Abstract

Summary

A Caucasian man in his 60s with recent diagnosis of metastatic renal cell carcinoma presented to the emergency department with a 5-day history of severe polyuria, polydipsia and fatigue and 1-day history of confusion, abdominal pain, nausea and vomiting. Investigations revealed an overlap of diabetic ketoacidosis (DKA) and hyperosmolar hyperglycaemic state (HHS). He had received the first dose of immunotherapy with nivolumab and ipilimumab 3 weeks prior to this attendance. New-onset type 1 diabetes (T1DM) was confirmed based on the clinical features at presentation, seropositivity for glutamic acid decarboxylase antibodies and significant insulin deficiency. He is currently on a multiple daily injections of insulin and uses intermittent-scanned glucose monitoring. Given the irreversible impact on beta-cell function and clinical response with insulin resulting in improved diabetes control, immunotherapy was resumed for his metastatic cancer with good radiological response. Although rare, new-onset T1DM can present with DKA and HSS overlap after a single dose of nivolumab/ipilimumab in individuals without pre-existing history of diabetes.

Learning points

Although rare, new onset of T1DM after immunotherapy can present with DKA and HSS overlap after a single dose of nivolumab/ipilimumab in individuals without pre-existing history of diabetes and normal glycaemic parameters.
Due to the irreversible destruction of beta-cells, treatment with steroids is not indicated in contrast to other settings such as immunotherapy-induced hypophysitis.
Presence of low c-peptide levels post-acute presentation is indicative of an irreversible impact on beta-cell function and supports resuming immunotherapy given the significant benefits on cancer prognosis.
Clinicians must maintain a high index of suspicion in regards to diagnosis and management of new-onset type 1 diabetes and advice patients on reporting symptoms suggestive of diabetes and/or diabetes-related hyperglycaemic emergencies.

An Anti-CD3 Antibody, Teplizumab, in Relatives at Risk for Type 1 Diabetes

Kevan C. Herold, Brian Bundy, S Alice Long … (2019)

Type 1 diabetes is a chronic autoimmune disease that leads to destruction of insulin-producing beta cells and dependence on exogenous insulin for survival. Some interventions have delayed the loss of insulin production in patients with type 1 diabetes, but interventions that might affect clinical progression before diagnosis are needed.

The Programmed Death-1 (PD-1) Pathway Regulates Autoimmune Diabetes in Nonobese Diabetic (NOD) Mice

Mohammed Javeed I Ansari, Alan Salama, Tanuja Chitnis … (2003)

Programmed death-1 (PD-1) receptor, an inhibitory costimulatory molecule found on activated T cells, has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. We investigated the role of this pathway in the development of autoimmune diabetes. PD-1 or PD-L1 but not PD-L2 blockade rapidly precipitated diabetes in prediabetic female nonobese diabetic (NOD) mice regardless of age (from 1 to 10-wk-old), although it was most pronounced in the older mice. By contrast, cytotoxic T lymphocyte–associated antigen 4 (CTLA-4) blockade induced disease only in neonates. Male NOD mice also developed diabetes after PD-1–PD-L1 pathway blockade, but NOR mice, congenic to NOD but resistant to the development of diabetes, did not. Insulitis scores were significantly higher and frequency of interferon γ–producing GAD-reactive splenocytes was increased after PD-1–PD-L1 pathway blockade compared with controls. Interestingly, PD-L1 but not PD-L2 was found to be expressed on inflamed islets of NOD mice. These data demonstrate a central role for PD-1–PD-L1 interaction in the regulation of induction and progression of autoimmune diabetes in the NOD mouse and provide the rationale to develop new therapies to target this costimulatory pathway in this disease.
