Performance of Modified ALMS and BLISS Criteria with Standard of Care Treatment in Two US Health Care Systems.

OBJECTIVE: A retrospective cohort study was undertaken in a predominantly Black population undergoing standard treatment for lupus nephritis (LN) to estimate the incidence of, and risk factors for, complete response (CR) according to modified Aspreva Lupus Management Study (mALMS) and modified Belimumab International Study in Lupus Nephritis (mBLISS) criteria by 12 months. METHODS: Patients with biopsy-proven LN class III or IV ± V, urine protein-to-creatinine ratio of ≥1gm/gm and estimated glomerular filtration rate of >50 ml/minute/1.73 m2 at the time of the incident LN flare were included. The clinical, treatment, and laboratory factors associated with CR were identified using multivariable Cox regression. RESULTS: Of 173 patients, 86.1% were women, 77.5% were Black, and over half (59.5%) had non-commercial insurance. By 12 months, 20.6% (95% confidence interval (95% CI) 14.6-28.6%) achieved mALMS CR and 33.7% (95% CI 26.4-42.4%) achieved mBLISS CR. Factors associated with mBLISS CR were commercial insurance (adjusted CR ratio = 3.5 [95% CI 1.9-6.7]; P < 0.001), albumin (adjusted CR ratio = 1.8 per 1 gm/dl increase in albumin; P = 0.02), and low C4 (adjusted CR ratio = 2.6; P = 0.03). Cumulative incidence of end-stage renal disease (ESRD) at 3 years was 23.1% (95% CI 15.7-31.3%) and 6.1% (95% CI 2.8-11.1%) for death. Patients with non-commercial insurance were more likely to develop ESRD, with cumulative incidence of 30.4% (95% CI 19.6-41.9%) compared to 12.7% (95% CI 5.0-24.2%) for patients with commercial insurance (P = 0.024). CONCLUSION: In a primarily Black, uninsured LN population, despite achieving similar CR rates at 12 months, the incidence of ESRD and death exceeded those observed in controlled clinical trials with placebo arms.

The Burden of Childhood Atopic Dermatitis in the Primary Care Setting: A Report from the Meta-LARC Consortium.

BACKGROUND: Little is known about the burden of atopic dermatitis (AD) encountered in US primary care practices and the frequency and type of skin care practices routinely used in children. OBJECTIVE: To estimate the prevalence of AD in children 0 to 5 years attending primary care practices in the United States and to describe routine skin care practices used in this population. DESIGN: A cross-sectional survey study of a convenience sample of children under the age of 5 attending primary care practices for any reason. SETTING: Ten primary care practices in 5 US states. RESULTS: Among 652 children attending primary care practices, the estimated prevalence of ever having AD was 24% (95% CI, 21-28) ranging from 15% among those under the age of 1 to 38% among those aged 4 to 5 years. The prevalence of comorbid asthma was higher among AD participants compared to those with no AD, namely, 12% and 4%, respectively (P < .001). Moisturizers with high water:oil ratios were most commonly used (ie, lotions) in the non-AD population, whereas moisturizers with low water:oil content (ie, ointments) were most common when AD was present. CONCLUSIONS: Our study found a large burden of AD in the primary care practice setting in the US. The majority of households reported skin care practices that may be detrimental to the skin barrier, such as frequent bathing and the routine use of moisturizers with high water: oil ratios. Clinical trials are needed to identify which skin care practices are optimal for reducing the significant burden of AD in the community.
