Abstract
            Type 1 diabetes (T1D) is an autoimmune disease characterized by insulin deficiency and  impaired glucose regulation. While daily insulin therapy is life-saving, many patients struggle  to achieve optimal glycemic control, leading to microvascular complications affecting various  organs, including the kidneys and the liver. This review aims to summarize the current state of  knowledge regarding the pathogenesis of hepatic and renal complications in T1D, highlight  recent advances in potential therapeutic targets, and provide evidence-based recommendations  for mitigating end-organ damage. Chronic hyperglycemia drives diabetic complications through  several interrelated mechanisms, including increased polyol pathway flux, advanced glycation  end-product (AGE) formation, protein kinase C activation, and mitochondrial reactive oxygen  species overproduction. In the liver, these processes contribute to non-alcoholic fatty liver  disease, with up to 50% of T1D patients developing hepatic steatosis. Diabetic nephropathy,  affecting 25%–40% of long-term T1D patients, is characterized by glomerular basement  membrane thickening, mesangial expansion, and tubulointerstitial fibrosis. Recent innovations  in T1D management include genomics and precision medicine approaches, gut microbiome  modulation, nanomedicine, and artificial intelligence-driven glucose monitoring systems.  Emerging immunotherapies aim to fundamentally modify the autoimmune response in T1D.  Mitigating T1D complications requires intensive glycemic control, targeted pharmacotherapy,  and lifestyle modifications. Emerging therapies and precision medicine approaches offer  promising avenues. Ongoing research into molecular mechanisms remains crucial for developing  novel interventions and improving long-term outcomes in T1D patients.
