Cost-effectiveness modeling studies of global endometrial ablation (GEA) for treatment of abnormal uterine bleeding (AUB) from a US perspective are lacking. The objective of this study was to model the cost-effectiveness of GEA vs. hysterectomy for treatment of AUB in the United States from both commercial and Medicaid payer perspectives. The study team developed a 1-, 3-, and 5-year semi-Markov decision-analytic model to simulate 2 hypothetical patient cohorts of women with AUB—1 treated with GEA and the other with hysterectomy. Clinical and economic data (including treatment patterns, health care resource utilization, direct costs, and productivity costs) came from analyses of commercial and Medicaid claims databases. Analysis results show that cost savings with simultaneous reduction in treatment complications and fewer days lost from work are achieved with GEA versus hysterectomy over almost all time horizons and under both the commercial payer and Medicaid perspectives. Cost-effectiveness metrics also favor GEA over hysterectomy from both the commercial payer and Medicaid payer perspectives—evidence strongly supporting the clinical-economic value about GEA versus hysterectomy. Results will interest clinicians, health care payers, and self-insured employers striving for cost-effective AUB treatments. ( Population Health Management 2015;18:373–382)

AbstractAlemtuzumab and rabbit antithymocyte globulin (rATG) are commonly used for induction therapy in renal transplantation. This retrospective, single‐center, cohort study evaluated cumulative incidence of one‐yr biopsy‐proven acute rejection (BPAR) among 200 consecutive primary non‐sensitized kidney transplant recipients who received either alemtuzumab (n = 100) or rATG (n = 100) induction followed by rapid steroid taper, tacrolimus, and mycophenolate mofetil. Protocol biopsies, plasma and urine BK virus PCR, serum creatinine and iothalamate glomerular filtration rate (iGFR), were obtained at 1, 4, and 12 months from transplantation. The one‐yr BPAR rates were similar between the alemtuzumab and rATG groups; however, rejection Banff IA and higher was more common in the alemtuzumab arm (18% vs. 5%, p = 0.047). After adjusting for confounding variables, alemtuzumab was still associated with Banff IA and higher rejection (adjusted OR: 3.7, CI: 1.2–10.5, p = 0.02). Despite similar rates of BK viremia, more patients in the alemtuzumab arm developed BK nephropathy (16% vs. 3%, p = 0.046). One‐year iGFR (53.4 ± 20.2 vs. 71.9 ± 27.2 mL/min/1.73 m2, p = 0.002) and three‐yr graft survival (89.5% vs. 95%, p = 0.05) were lower in the alemtuzumab group. In low immunological risk kidney transplant recipients on steroid‐free immunosuppression, alemtuzumab was associated with more severe rejection and BK nephropathy compared to rATG.

Objective To describe the treatment and outcomes of patients with primary central nervous system (CNS) vasculitis. Methods We retrospectively studied a cohort of 163 consecutive patients with primary CNS vasculitis who were seen at the Mayo Clinic over a 29‐year period. We analyzed treatments, treatment responses, and factors predictive of outcomes. Results A favorable response was observed in 85% of patients treated with prednisone alone and in 80% of patients treated with prednisone and cyclophosphamide. Relapses were observed in 27% of patients, and 25% of patients had discontinued therapy by the time of the last followup visit. Treatment with prednisone alone was associated with more frequent relapses (odds ratio [OR] 2.90), while large vessel involvement (OR 6.14) and cerebral infarcts at the time of diagnosis (OR 3.32) were associated with a poor response to treatment. Prominent gadolinium‐enhanced cerebral lesions or meninges were linked with continued treatment at the last followup encounter (OR 2.28). Higher disability scores at the last followup visit were associated with increasing age at the time of diagnosis (OR 1.44) and cerebral infarctions (OR 3.74), while lower disability scores were associated with gadolinium‐enhanced cerebral lesions or meninges (OR 0.35) and cerebral amyloid angiopathy (OR 0.24). Increased mortality was associated with increasing age at diagnosis (hazard ratio [HR] 1.39), diagnosis by angiography (HR 3.28), cerebral infarction (HR 4.44), and large vessel involvement (HR 4.98), while reduced mortality was associated with gadolinium‐enhanced cerebral lesions or meninges (HR 0.20). Conclusion The majority of patients with primary CNS vasculitis responded to treatment. Recognition of findings at diagnosis that predict the course or outcome may aid in decision‐making regarding therapy.

Idiopathic dilated cardiomyopathy is a heritable, genetically heterogeneous disorder characterized by progressive heart failure. Dilated cardiomyopathy typically exhibits autosomal dominant inheritance, yet frequently remains clinically silent until adulthood. We sought to discover the molecular basis of idiopathic, non‐syndromic dilated cardiomyopathy in a one‐month‐old male presenting with severe heart failure. Previous comprehensive testing of blood, urine, and skin biopsy specimen was negative for metabolic, mitochondrial, storage, and infectious etiologies. Ophthalmologic examination was normal. Chromosomal microarray and commercial dilated cardiomyopathy gene panel testing failed to identify a causative mutation. Parental screening echocardiograms revealed no evidence of clinically silent dilated cardiomyopathy. Whole exome sequencing was carried out on the family trio on a research basis, filtering for rare, deleterious, recessive and de novo genetic variants. Pathogenic compound heterozygous truncating mutations were identified in ALMS1, diagnostic of Alström syndrome and prompting disclosure of genetic findings. Alström syndrome is a known cause for dilated cardiomyopathy in children yet delayed and mis‐diagnosis are common owing to its rarity and age‐dependent emergence of multisystem clinical manifestations. At six months of age the patient ultimately developed bilateral nystagmus and hyperopia, features characteristic of the syndrome. Early diagnosis is guiding clinical monitoring of other organ systems and allowing for presymptomatic intervention. Furthermore, recognition of recessive inheritance as the mechanism for sporadic disease has informed family planning. This case highlights a limitation of standard gene testing panels for pediatric dilated cardiomyopathy and exemplifies the potential for whole exome sequencing to solve a diagnostic dilemma and enable personalized care. © 2015 Wiley Periodicals, Inc.
