The consequences of atopic dermatitis reach beyond the skin and past childhood. Patients with atopic dermatitis are at risk of developing allergic comorbidities, but less is known about the associations between atopic dermatitis and non-allergic conditions. Understanding these non-allergic comorbidities has the potential to improve patient outcomes and to help mitigate the cost and burdens associated with these conditions. Atopic dermatitis is associated with cutaneous bacterial infections, more severe forms/courses of cutaneous viral infections, and extra-cutaneous infections. Atopic dermatitis is also associated with several mental health comorbidities particularly attention-deficit hyperactivity disorder, anxiety, and depression. Data are largely inconsistent for specific cancers, but atopic dermatitis appears to protect against malignancy overall; severe long-term atopic dermatitis is associated with adult lymphomas. Atopic dermatitis may also be associated with obesity, cardiovascular disease, and autoimmune disease, particularly alopecia areata and gastrointestinal immune-mediated disorders. Although the causative mechanisms underlying these associations are poorly understood, treating physicians should be aware of associations in seeking to alleviate the burden for patients with atopic dermatitis.

Atopic dermatitis affects a substantial number of children, many of whom seek initial treatment from their pediatrician or other primary care provider. Approximately two-thirds of these patients have mild disease and can be adequately managed at the primary care level. However, recent treatment guidelines are written primarily for use by specialists and lack certain elements that would make them more useful to primary care providers. This article evaluates these recent treatment guidelines in terms of evaluation criteria, treatment recommendations, usability, accessibility, and applicability to nonspecialists and integrates them with clinical evidence to present a streamlined severity-based treatment model for the management of a majority of atopic dermatitis cases. Because each patient's situation is unique, individualization of treatment plans is critical as is efficient communication and implementation of the plan with patients and caregivers. Specifically, practical suggestions for individualizing, optimizing, implementing, and communicating treatment plans such as choosing a moisturizer formulation, avoiding common triggers, educating patients/ caregivers, providing written treatment plans, and scheduling physician follow-up are provided along with a discussion of available resources for patients/caregivers and providers.

Background and ObjectiveCertain patients with heart failure (HF) are unable to tolerate spironolactone therapy due to hyperkalemia. Patiromer is a novel agent used to treat hyperkalemia and has been shown to be efficacious, safe, and well-tolerated. The potential clinical outcomes and economic value of using patiromer and spironolactone in patients with HF unable to otherwise tolerate spironolactone due to hyperkalemia are unclear. The objective of this analysis was to model the potential pharmacoeconomic value of using patiromer and spironolactone in patients with a history of hyperkalemia that prevents them from utilizing spironolactone.MethodsWe performed a cost-effectiveness analysis of treatment with patiromer, spironolactone, and an angiotensin-converting enzyme inhibitor (ACEI) in patients with New York Heart Association (NYHA) class III–IV HF compared with ACEI alone. A Markov model was constructed to simulate a cohort of 65-year-old patients diagnosed with HF from the payer perspective across the lifetime horizon. Clinical inputs were derived from the RALES and OPAL-HK randomized trials of spironolactone and patiromer, respectively. Utility estimates and costs were derived from the literature and list prices. Outcomes assessed included hospitalization, life expectancy, and quality-adjusted life-years (QALYs), costs, and the incremental cost-effectiveness ratio (ICER). One-way and probability sensitivity analyses were performed to test the robustness of the model findings.ResultsTreatment with patiromer–spironolactone–ACEI was projected to increase longevity compared with ACEI alone (5.29 vs. 4.62 life-years gained, respectively), greater QALYs (2.79 vs. 2.60), and costs (US$28,200 vs. US$18,200), giving an ICER of US$52,700 per QALY gained. The ICERs ranged from US$40,000 to US$85,800 per QALY gained in 1-way sensitivity analyses.ConclusionOur results suggest that the use of spironolactone–patiromer–ACEI may provide clinical benefit and good economic value in patients with NYHA class III–IV HF unable to tolerate spironolactone due to hyperkalemia.Electronic supplementary materialThe online version of this article (10.1007/s40273-018-0709-3) contains supplementary material, which is available to authorized users.
