Ren Z, et al. - Researchers ascertained if pemphigus and pemphigoid were related to increased likelihood of serious infections and the effect of such infections on mortality and cost of care. Data were evaluated from the 2002 to 2012 Nationwide Inpatient Sample, including a representative 20% sample of all hospitalizations in the US. Increased cutaneous, respiratory, multi-organ and systemic infections were seen in adults with pemphigus or pemphigoid which were related to considerable inpatient mortality and cost burden. Furthermore, with respect to infections in patients with pemphigus or pemphigoid significant clinical and healthcare disparities were noted.
