Brief summary

Adolescents and young adults (AYA) with type 2 diabetes (T2D) have a more severe phenotype than what is seen in youth-onset type 1 diabetes or adult-onset T2D including earlier kidney and cardiovascular disease complications; and prioritizing new treatments, either for standalone use or in combination with other therapies is critical. T2D triggers the release of proinflammatory mediators called cysteinyl leukotrienes leading to damage to the kidneys and blood vessels. This clinical trial will evaluate the effects of montelukast, a cysteinyl leukotriene inhibitor, on kidney and vascular function in AYA with T2D to help direct future diabetes care to limit diabetic kidney and cardiovascular disease complications.

Design outcomes

Primary

MeasureTime frameDescription
Change in renal vascular resistance (RVR)0 and 6 monthsChange in RVR from baseline to 6 months. RVR is calculated as mean arterial pressure (MAP)/renal blood flow (RBF). MAP is measured using a blood pressure cuff and RBF is calculated using p-aminohippurate clearance (PAH clearance).

Secondary

MeasureTime frameDescription
Change in Brachial artery flow mediated dilation (FMD)0 and 6 monthsChange in FMD from baseline to 6 months, measured using high-resolution ultrasonography
Change in aortic pulse-wave velocity (PWV)0 and 6 monthsChange in PWV from baseline to 6 months, measured using a transcutaneous tonometer
Change in endovascular biopsy0 and 6 monthsChange in endovascular biopsy from baseline to 6 months. Venous endothelial cells will be collected from the intima of the vessel using 2 sterile J-wires advanced and retracted through an 18-gauge catheter, then will be incubated with monoclonal antibodies for Nf-KB.
Change in urinary sCD1630 and 6 months
Change in urinary MCP-10 and 6 months
Change in plasma MCP-10 and 6 months
