The Triple Threat in Diabetes: Interconnection of Multidrug Resistance and Systemic Complications

Abstract

Diabetes mellitus represents a major global health challenge, predisposing individuals to chronic metabolic dysfunction, vascular complications, and increased susceptibility to infections. The rising prevalence of multidrug-resistant (MDR) organisms adds a critical layer of complexity, forming a “triple threat” where diabetes, antimicrobial resistance, and systemic complications reinforce each other. Impaired immunity in diabetic patients facilitates recurrent or persistent MDR infections, while prolonged infection and inflammation accelerate both macrovascular and microvascular damage. This interplay drives the progression of atherosclerosis, cardiovascular events, nephropathy, retinopathy, and neuropathy, worsening clinical outcomes and elevating healthcare costs. The convergence of these conditions establishes a self-perpetuating cycle of hyperglycemia, infection, and organ injury. Breaking this cycle demands integrated strategies that go beyond routine glycemic control, including antimicrobial stewardship, infection-prevention measures, and multidisciplinary approaches to patient management. Recognizing the interconnection between diabetes and MDR pathogens is essential for reducing disease burden and improving long-term outcomes.
