Abstract
BACKGROUND Detecting airway inflammation non-invasively in infants with cystic fibrosis (CF) is difficult. We hypothesized that markers of inflammation in CF [IL-1β, IL-6, IL-8, IL-10, IL-17A, neutrophil elastase (NE) and tumor necrosis factor (TNF-α)] could be measured in infants with CF from nasal fluid and would be elevated during viral infections or clinician-defined pulmonary exacerbations (PEx). METHODS We collected nasal fluid, nasal swabs, and hair samples from 34 infants with CF during monthly clinic visits, sick visits, and hospitalizations. Nasal fluid was isolated and analyzed for cytokines. Respiratory viral detection on nasal swabs was performed using the Luminex NxTAG® Respiratory Pathogen Panel. Hair samples were analyzed for nicotine concentration by reverse-phase high-performance liquid chromatography. We compared nasal cytokine concentrations between the presence and absence of detected respiratory viruses, PEx, and smoke exposure. RESULTS A total of 246 samples were analyzed. Compared to measurements in the absence of respiratory viruses, mean concentrations of IL-6, IL-8, TNF-α, and NE were significantly increased while IL-17A was significantly decreased in infants positive for respiratory viruses. IL-17A was significantly decreased and NE increased in those with a PEx. IL-8 and NE were significantly increased in infants with enteric pathogen positivity on airway cultures, but not P. aeruginosa or S. aureus. Compared to those with no smoke exposure, there were significantly higher levels of IL-6, IL-10, and NE in infants with detectable levels of nicotine. CONCLUSIONS Noninvasive collection of nasal fluid may identify inflammation in infants with CF during changing clinical or environmental exposures.

Pediatr Pulmonol 2021; 56:457-464. [PMID: 33295695 DOI: 10.1002/ppul.25213] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 11/30/2020] [Accepted: 12/02/2020] [Indexed: 11/10/2022]
Abstract
OBJECTIVES Caregivers of infants with cystic fibrosis (CF) carry a heavy treatment burden for their child along with the inherent difficulties of raising an infant. This study investigated the impact of self-reported caregiver mental health diagnoses and social barriers during the 1st year of life on clinical outcomes. METHODS A retrospective chart review was conducted for infants seen in a large tertiary hospital CF clinic over a 5-year period. Baseline characteristics were collected, and documentation from physician and social work notes were reviewed. Demographics and clinical characteristics were compared by the presence or absence of self-reported mental health diagnoses, social barriers, and "emotional concern." RESULTS Analyses were conducted on 71 patients. Thirty-five percent of caregivers disclosed mental health diagnoses, 52% identified social barriers to care, and 55% reported feeling upset or fatigued. Having a caregiver with a self-reported mental health diagnosis was associated with tobacco smoke exposure (p < .001) and increased odds of hospitalizations (odds ratio [OR], 3.01; 95% confidence interval [CI], 1.49-6.06), emergency department/urgent care visits (OR, 3.17; 95% CI, 1.32-7.64), and longer lengths of stay (OR, 1.93; 95% CI, 1.69-2.20). Caregivers who expressed emotional concern had infants with significantly lower weight-for-length percentiles (p = .012). DISCUSSION Caregiver mental health and social barriers to care are important determinants to address as they may impact clinical outcomes in infants with CF. Identifying barriers and struggles early increases the likelihood that clinical teams can intervene and provide support. Further research into mental health and socioeconomic barriers faced by caregivers of infants with CF is crucial.
