Background: Drug interactions are an important risk in transplant patients. Case presentation: This case describes an incident where a patient with islet transplantation, who was using tacrolimus as part of the immunosuppressant regime, was started on a course of clarithromycin and experienced nephrotoxicity and neurotoxicity. He was an outpatient at that time and was managed with temporary cessation of tacrolimus until the tacrolimus level returned to target and his symptoms resolved. He recovered well and was resumed on his usual dosage of tacrolimus to prevent rejection of islets.
Conclusion: Care should be taken with commonly used antibiotics to avoid potentially dangerous interactions with immunosuppressant drugs.

Organ transplantation faces critical challenges, including donor shortages, suboptimal preservation, ischemia-reperfusion injury (IRI), and immune rejection. Nanotechnology offers transformative solutions by leveraging precision-engineered materials to enhance graft viability and outcomes. This review highlights nanomaterials' roles in revolutionizing organ preservation.

MR409, a synthetic growth hormone-releasing hormone (GHRH) analogue, has demonstrated therapeutic potential in enhancing islet cell transplantation efficacy in diabetes mice and exerts beneficial effects on cardiovascular diseases. The present study investigated the renoprotective effects of MR409 on db/db and streptozotocin (STZ)-induced diabetic mice, focusing on its role in modulating oxidative stress and ferroptosis. db/db or STZ mice combined with high fat diet were used to establish the type 2 diabetic models.

The pancreatic islets of Langerhans, which are composed of α, β, δ, ε, and PP cells, orchestrate systemic glucose homeostasis through tightly regulated hormone secretion. Although the precise mechanisms involving β cells in the onset and progression of diabetes have been elucidated and insulin replacement therapy remains the primary treatment modality, the regulatory processes, functions, and specific roles of other pancreatic islet hormones in diabetes continue to be the subject of ongoing investigation. At present, a comprehensive review of the secretion and regulation of pancreatic islet cell hormones as well as the related mechanisms of diabetes is lacking.

Background: The long-term clinical efficacy of intraportal islet transplantation is hampered by islet loss due to inflammation, oxidative stress, and insufficient vascularization. This study explores the venous sac as an alternative implantation site for islet transplantation in large animal models.
Methods: An immunosuppressed, diabetic cynomolgus monkey received allogeneic islet implants in its mesenteric venous sac, with metabolic assessments over 112 days.

Islet transplantation offers a promising therapeutic strategy for type 1 diabetes patients with inadequate glycemic control or severe complications. Islet encapsulation using biocompatible materials presents a potential solution to reduce immune rejection. This study fabricated and characterized Schiff base hydrogels (CMOCs) composed of varying ratios of carboxymethyl chitosan (CMCS) and oxidized carboxymethyl starch (OCMS).
