Complex Mechanisms Underlying the Coexistence of Diabetic Complications, Chronic Kidney Disease, and Hemorrhagic Stroke: A Case Report

Diabetes mellitus type 2 is a chronic metabolic disease that presents a growing global health challenge. Its long-term complications, including nephropathy, neuropathy, and retinopathy, significantly contribute to patient morbidity and the healthcare burden. Diabetic kidney disease, one of the significant complications, often progresses to end-stage renal failure, necessitating renal replacement therapy. This case report describes a 67-year-old man with longstanding type 2 diabetes mellitus and hypertension complicated by progressive chronic kidney disease, diabetic foot syndrome, and subsequent neurological and psychiatric manifestations. The patient was initially admitted to the nephrology department for predialysis assessment and optimization of anemia management. Over the following months, he experienced recurrent hospitalizations due to diabetic foot ulceration, phlegmon requiring surgical intervention, and episodes of psychotic syndrome related to metabolic and vascular factors. The final admission to the stroke unit revealed a left thalamic intracerebral hemorrhage associated with severe arterial hypertension and worsening disturbances of consciousness. A multidisciplinary approach was employed, including nephrological, surgical, psychiatric, and neurological care, along with complex polypharmacotherapy and insulin therapy. This case illustrates the intricate relationship between diabetes, chronic kidney disease, and cerebrovascular complications. It emphasizes the importance of early nephrological and metabolic monitoring, personalized treatment strategies, and ongoing interdisciplinary collaboration. Early recognition and management of diabetic complications can significantly improve prognosis and prevent life-threatening outcomes in patients with advanced type 2 diabetes mellitus.
