Type 1 diabetes mellitus (T1DM) results from autoimmune destruction of pancreatic β-cells, while type 2 diabetes mellitus (T2DM) is characterized primarily by peripheral insulin resistance with progressive β-cell dysfunction. Despite advances in pharmacologic and self-monitoring therapies, many patients fail to achieve recommended glycemic targets. Continuous glucose monitoring (CGM) has emerged as a transformative technology with the potential to address persistent gaps in diabetes management. This review critically synthesizes the current literature on CGM-associated clinical outcomes, cost implications, and technological limitations across major commercial platforms-Dexcom, Medtronic, and FreeStyle Libre-and examines future directions in CGM innovation. A comprehensive review of randomized controlled trials, prospective cohort studies, real-world registries, and meta-analyses was performed to evaluate CGM use in T1DM and T2DM populations across pediatric, adult, and older adult cohorts. Outcomes assessed included HbA1c, time in range (TIR), hypoglycemic events, healthcare utilization, cost, patient-reported outcomes, and adverse effects. CGM use was consistently associated with improvements in glycemic control, with HbA1c reductions ranging from approximately 0.4% to 1.5% across studies, and the greatest benefits observed in patients with higher baseline HbA1c. Hypoglycemic events were substantially reduced, including a 72% reduction reported in the HypoDE trial and reductions of up to 79% in the DIAMOND trial. CGM use was also associated with increased TIR, decreased glycemic variability, and reduced rates of diabetic ketoacidosis hospitalizations and emergency department visits, yielding meaningful cost offsets despite higher upfront device costs. Patient-reported outcomes-including treatment satisfaction, self-efficacy, and quality of life-improved consistently across studies. Among the major platforms, Dexcom systems demonstrated robust evidence in both T1DM and T2DM populations; Medtronic's MiniMed 780G achieved mean TIR values approaching 78.8% with optimal settings through automated insulin delivery; and FreeStyle Libre demonstrated particular value in T2DM populations on basal insulin or non-insulin therapy. Limitations included dermatologic complications, sensor lag during rapid glycemic change, alarm fatigue, accuracy variability across the hypoglycemic range, and procedural and mechanical issues. CGM technology has fundamentally reshaped contemporary diabetes care, with consistent and reproducible benefits across glycemic, economic, and patient-centered domains in both T1DM and T2DM populations. While important device-related and patient-centered limitations persist, the cumulative evidence support broader integration of CGM into routine diabetes management.

With an estimated prevalence of 2.4 cases per million person-years in North America, PACNS represents one of the rarest vasculitides and continues to pose significant diagnostic and therapeutic challenges due to its heterogeneous clinical manifestations and lack of specific biomarkers. This critical review article provides a comprehensive overview of PACNS with emphasis on: (i) current understanding of pathophysiology and unique variations of clinical presentation, (ii) challenges and strategies in reaching a definitive diagnosis, and (iii) evaluation and comparison of pharmacological and neuromodulatory therapies currently available. Recent advances in understanding pathophysiology have identified elevated interleukin-17 in cerebrospinal fluid, distinct gene expression profiles including upregulation of TBC1D3C and TBC1D3L genes, and immune cell profiling showing increased intrathecal NK-cell and B-cell frequencies. Three histopathological subtypes have been characterized: granulomatous vasculitis (32-61%), lymphocytic vasculitis (24-79%), and necrotizing vasculitis (14-42%). Emerging biomarkers including neurofilament light chain, circulating endothelial cells, and soluble triggering receptor expressed on myeloid cells 2 (sTREM2) show promise for diagnosis and disease monitoring. Advanced neuroimaging modalities, particularly high-resolution vessel wall magnetic resonance imaging and positron emission tomography, demonstrate utility in detecting vessel wall inflammation and guiding biopsy site selection. Treatment approaches include glucocorticoids combined with cyclophosphamide for induction therapy, with mycophenolate mofetil, rituximab, azathioprine, and methotrexate used for maintenance. TNF-α inhibitors have shown efficacy in refractory cases. Despite treatment, mortality ranges from 8-23%, and approximately 25% of patients experience severe disability. PACNS remains a diagnostically challenging condition requiring high clinical suspicion and comprehensive workup. Recent advances in understanding immunopathological mechanisms, identification of novel biomarkers, and development of advanced neuroimaging techniques offer promise for earlier diagnosis and more targeted therapeutic interventions. Brain biopsy remains the gold standard for diagnosis, though emerging non-invasive diagnostic modalities may reduce reliance on invasive procedures.
