Abstract:
Background and Aims: Treatment-induced neuropathy in diabetes(TIND) is a transient, painful peripheral neuropathy occasionally with autonomic component, occurring with rapid glycaemic improvement. Hybrid closed loop(HCL) continuous subcutaneous insulin infusion(CSII) in type 1 diabetes(T1D) can improve glucose levels rapidly. Method(s): Retrospective review of two cases. Case 1: 27- year-old male, T1D for 16years, disengagement, maculopathy switched from basal-bolus insulin to HCL-CSII(Omnipod5- DexcomG6). Case 2: 44-year-old female, T1D for 42years, disengagement laser treated retinopathy, neuropathy, toe amputation switched from basal-bolus insulin to HCL-CSII(Omnipod5- DexcomG6). Result(s): Case 1: Pre-HCL HbA1c107mmol/mol. 3months post HCL HbA1c 69mmol/mol. He reported neuropathic pain in lower limbs, commenced amitriptyline for 3months with resolution. He also developed proliferative retinopathy. Case 2: Pre- HCL HbA1c96mmol/mol improved to 54mmol/mol in 6months. She developed severe neuralgic pain in both feet, improved with Pregabalin for 3months. There was no deterioration in retinopathy. Conclusion(s): TIND is more common in T1D, pathophysiology may be endoneurial ischaemia and microvascular changes due to relative hypoglycaemic state. Diagnostic criteria include (i)decrease in HbA1c by 2%(22mmol/mol) over 3months (ii)neuropathic pain and/or autonomic symptoms within 8weeks after decrease in HbA1c (iii)acute onset of neuropathic pain and/ or autonomic dysfunction for more than 2weeks requiring medical attention. It is self-limiting, lasting from weeks to months. Symptomatic treatment include antiepileptics(pregabalin) and tricyclic antidepressants are effective. There are no reported cases of TIND with HCL-CSII in literature. Our two cases highlight TIND, like worsening retinopathy, is a potential complication of rapid improvement in glycaemic control with HCL-CSII in patients with pre-existing hyperglycaemia and patients' needs counselling about the potential short-term risks.
