Evolving Nutritional Needs in Cystic Fibrosis.

The course of cystic fibrosis (CF) as a nutritional illness is diverging since the introduction of highly effective modulator therapy, leading to more heterogeneous phenotypes of the disease despite CF genetic mutations that portend worse prognosis. This may become more evident as we follow the pediatric CF population into adulthood as some highly effective modulator therapies (HEMT) are approved for those as young as 1 year old. This review will outline the current research and knowledge available in the evolving nutritional health of people with CF as it relates to the impact of HEMT on anthropometrics, body composition, and energy expenditure, exocrine and endocrine pancreatic insufficiencies (the latter resulting in CF-related diabetes), vitamin and mineral deficiencies, and nutritional health in CF as it relates to pregnancy and lung transplantation.

The clinical impact of the Covid-19 pandemic first wave on patients with cystic fibrosis in New York.

BACKGROUND: People with cystic fibrosis (pwCF) may be at risk of complications from COVID-19 but the impact of COVID-19 on pwCF remains unknown. METHODS: We conducted a multicenter retrospective cohort study to assess the impact of the COVID-19 pandemic first wave on pwCF in the New York metropolitan area (NY) from March 1, 2020 to August 31, 2020. Objectives were to determine (1) the prevalence of COVID-19 by PCR and IgG antibody testing, (2) the clinical characteristics of COVID-19, (3) delay in routine outpatient care, and (4) the effect on anxiety and depression in pwCF. RESULTS: There were 26 COVID-19 cases diagnosed by PCR or antibody testing among the study cohort of 810 pwCF. The prevalence of COVID-19 by PCR (1.6%) and IgG antibody (12.2%) testing was low. 58% of cases were asymptomatic and 82% were managed at home. 8% were hospitalized and 1 person died. 89% of pwCF experienced delay in care. The prevalence of anxiety increased from 43% baseline to 58% during the pandemic (P<0.01). In post-hoc analysis, the proportion of patients with diabetes (38% versus 16%, P<0.01) and pancreatic insufficiency (96% versus 66%, P<0.01) were higher while CFTR modulator use was lower (46% versus 65%, P = 0.05) in pwCF who tested positive for COVID-19. CONCLUSIONS: The prevalence of COVID-19 among pwCF in NY during the pandemic first wave was low and most cases were managed at home. CFTR modulators may be protective. PwCF experienced delay in routine care and increased anxiety.

Application of a microsystem-based project to improve the inpatient care of adults with cystic fibrosis.

BACKGROUND: Patients with cystic fibrosis (CF) hospitalized for pulmonary exacerbations complained of delayed and missed treatments. We analyzed the complaints and implemented two microsystem-based quality initiatives to improve care. METHODS: A prospective, observational study using quantitative and qualitative data collection strategies was conducted. Two interventions were implemented: a CF order set followed 9 months later by a self-administration program. MEASUREMENTS AND MAIN RESULTS: Thirty-six of 40 patients with CF received initial respiratory therapy within 2 hours of admission compared with 1 of 17 before intervention. Initial antibiotic administration time was reduced from a mean of 18 hours to within 4 hours in the majority of admissions after implementation of quality initiatives. The interventions led to improved medication delivery and increased satisfaction. Hospital length of stay for patients with CF decreased from a mean of 9.5 to 7.8 days. CONCLUSION: Application of a microsystem-based strategy that engaged patients and families as well as caregivers brought about substantial changes in CF care delivery, increased satisfaction among staff and patients, and decreased hospital length of stay.
