OBJECTIVE: To estimate the incidence rates of kidney-related clinical outcomes among patients with tuberous sclerosis complex (TSC)-related angiomyolipoma (AML) compared to an age-matched control cohort in the United States.
MATERIALS AND METHODS: This was a retrospective, observational study. Administrative data from the MarketScan Research Databases were used to select patients with TSC and renal AML. An age-matched group with no TSC or renal AML was identified for comparison. Outcomes were incidence rates per 100 patient-years and number of months to development of hematuria, chronic kidney disease, renal hemorrhage, kidney failure, and inpatient death.
RESULTS: Among the commercially insured TSC-renal AML patients (N = 605) and matched controls (N = 1815), 37.2% were <18 years old. Among Medicaid TSC-renal AML patients (N = 246) and matched controls (N = 738), 38.6% were aged <18. In the commercial sample, in both age groups (<18 and ≥18), the incidence rate of each clinical outcome measured was higher in the TSC-renal AML cohort than in the control cohort, with several differences reaching statistical significance. Compared with younger patients, older TSC-renal AML patients had higher incidence rates of clinical outcomes (hematuria: 20.4 vs 8.7; chronic kidney disease: 9.6 vs 3.5; renal hemorrhage 2.7 vs 0.7; kidney failure: 1.9 vs 0.4) and took less time on average to develop each clinical outcome. A similar pattern of results was observed among patients with Medicaid insurance.
CONCLUSION: TSC-renal AML patients are at significantly higher risk for renal morbidity relative to the general population.
