The patients, aged between 5 and 12 years, exhibited the phenotypic variability associated with TMEM173-activating mutations,2-4 with lung disease and systemic inflammation being the major features ...in patient 1 (P1) and patient 3 (P3), while in patient 2 (P2) skin involvement was most prominent (Fig 1; see Supplemental Text and Table E1 in this article's Online Repository at www.jacionline.org). Modest and incomplete downregulation of ISG was recently described in splenic B cells of mice treated with tofacitinib, a JAK1/3 inhibitor, with differential signaling effects suggesting currently poorly understood facets of IFN regulation.9 In this regard, our kinetic ex vivo experiments provide insights into the rapid dynamic changes in IFN signaling secondary to JAK1 blockade.
Background Most children with primary immunodeficiencies (PIDs) now reach adulthood. However, few studies have evaluated their health status and health-related quality of life (HRQoL). Objective To ...investigate long-term morbidity, the French Reference Center for PIDs initiated a prospective multicenter cohort: the French Childhood Immune Deficiency Long-term Cohort. The data collected were used to assess the physical health condition of patients who reached adulthood and the effect on their quality of life. Methods Patients were asked to complete health status questionnaires. A severity score (grade 1 mild to grade 4 life-threatening) was assigned to each health condition. The HRQoL of patients was compared with age- and sex-matched French normal values by using the 36-item Short-Form Survey (SF-36) HRQoL questionnaire. Results Among 329 participants, the mean age at evaluation was 27.6 years, with a 21-year mean follow-up after diagnosis; 43% reported at least 1 grade 4 health condition, and 86% reported at least 1 grade 3 (severe) or 4 health condition. Twenty-five (7.6%) patients had been treated for cancer. Compared with the French normal values, adults with PIDs scored significantly lower for all HRQoL domains. HRQoL was strongly associated with the burden of health conditions. The association with grade 4 or grade 3-4 health conditions was highly significant for all physical and mental domains. Conclusion Adults with PIDs diagnosed during childhood experienced a heavy burden of health conditions, which affected their HRQoL. Our results emphasize the need to closely monitor this vulnerable population.
