Implementation of an Outpatient Clinical Pharmacy Service at an Adult Cystic Fibrosis Center.

BACKGROUND: High treatment burden can adversely impact health outcomes in people with cystic fibrosis (PwCF). There is a continued need for medication adherence education and further research to evaluate impact of CF pharmacist interventions in an ambulatory care setting. OBJECTIVE(S): To evaluate whether pharmacist integration into an outpatient adult CF clinic can positively impact patient satisfaction and medication adherence through various pharmacist-based interventions. METHODS: At a single urban medical center, a clinical pharmacist on an adult CF care team conducted comprehensive counseling sessions with PwCF. During these visits, types of pharmacist interventions were documented. Patients were provided a baseline and post-counseling survey to assess satisfaction with the pharmacist visit. Adherence to cystic fibrosis transmembrane regulator (CFTR) modulator and mucolytics were tracked 12 months before and 12 months after the counseling session. RESULTS: A total of 723 pharmacist interventions were performed throughout 100 pharmacist visits in 100 PwCF. Most common interventions were inhaler technique education (17%), drug interaction identification (12%), provision of drug education material (12%), and medication refills (12%). Prior to any intervention, 97% of patients felt they could benefit from a pharmacist visit. Post-counseling survey results demonstrated that 98% of patients found pharmacist counseling to be beneficial. Medication adherence rate prior to pharmacy intervention was 81.9% for CFTR modulators and 62.5% for mucolytics, and 86.9% (p=0.143) and 63.6% (p=0.773), respectively, after pharmacist intervention. CONCLUSION: Integration of a clinical pharmacist within the CF clinic can help improve satisfaction and understanding of medication use among PwCF. Nearly all PwCF favorably perceived pharmacist counseling. We report that various pharmacist interventions including optimizing medication use knowledge, reinforcing adherence strategies, and streamlining timely access to treatment can contribute to enhanced care of PwCF.

Predictors of Sinonasal Improvement After Highly Effective Modulator Therapy in Adults with Cystic Fibrosis.

OBJECTIVES: The 22-question SinoNasal Outcome Test (SNOT-22) assesses chronic rhinosinusitis (CRS) severity. We aimed to identify predictors of SNOT-22 score improvement following highly effective modulator therapy (HEMT) initiation and to corroborate the SNOT-22 minimal clinically important difference (MCID) in adults with cystic fibrosis (CF). METHODS: Prospective observational data was pooled from four studies across 10 US centers investigating people with CF (PwCF) and CRS. Three studies evaluated HEMT's impact on CRS. For participants enrolled prior to HEMT initiation, SNOT-22 scores were obtained at baseline and after 3-6 months of HEMT. Multivariate regression identified predictors of improvement. Cronbach's alpha and four distribution-based methods were used to assess internal consistency and calculate the MCID of the SNOT-22. RESULTS: A total of 184 PwCF participated with mean baseline SNOT-22 scores ranging from 18.1 to 56.7. Cronbach's alpha was ≥0.90 across sites. Participants at sites with pre- and post-HEMT data reported improvement in SNOT-22 scores after initiating HEMT (all p < 0.05). Worse baseline SNOT-22 score (odds ratio (OR): 1.05, p < 0.001, 95% CI: 1.02-1.08), F508del homozygosity (OR: 4.30, p = 0.040, 95% CI: 1.14-18.99), and absence of prior modulator therapy (OR: 4.99, p = 0.017, 95% CI: 1.39-20.11) were associated with greater SNOT-22 improvement. The mean MCID calculated via distribution-based methods was 8.5. CONCLUSION: Worse baseline sinonasal symptoms, F508del homozygosity, and absence of prior modulator therapy predicted greater improvement after HEMT initiation. The mean MCID for SNOT-22 in PwCF is 8.5 points, similar to non-CF individuals with CRS, and provides a threshold specifically for PwCF. The SNOT-22 has strong internal consistency in PwCF. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:3965-3973, 2024.

Surgical and medical management of chronic rhinosinusitis in pediatric cystic fibrosis patients: Impact on olfactory symptoms.

BACKGROUND AND PURPOSE: Olfactory dysfunction (OD) commonly occurs in patients with sinonasal dysfunction, but the prevalence and severity of olfactory issues in adolescents with cystic fibrosis (AwCF) is unclear. OD may contribute to dietary deficiencies and exacerbate nutritional challenges. We sought to review literature on the effectiveness of medical and surgical management of sinonasal symptoms in AwCF and the associated impact on olfactory function. METHODS: We performed a systematic literature search of PubMed, Embase, Web of Science, and Ebsco CINAHL from 1980 to 2022 per PRISMA-ScR protocols to conduct a scoping review in an effort to compile data on study design, patient demographics, clinical characteristics and outcomes, along with risk of bias. RESULTS: Of 368 abstracts, 3 articles exclusively evaluated AwCF for a total of 34 patients. Two studies evaluated endoscopic sinus surgery (ESS) and dornase alfa. An additional 6 articles were included for mixed pediatric and adult CF populations totaling 313 patients. Interventions included ESS, elexacaftor-tezacaftor-ivacaftor (ETI), ivacaftor, saline, dornase alfa, hyaluronic acid, and hyaluronic acid-tobramycin combination. Outcome measures included subjective assessment of OD using non-validated (4/9) and validated (4/9) surveys, and psychophysical (1/9) smell testing. Studies evaluating ESS, FESS, dornase alfa, ivacaftor, and both hypertonic and isotonic saline reported statistically significant improvement in OD, whereas ETI failed to improve OD despite improvement in other quality of life measures. CONCLUSIONS: There is limited data regarding the impact of medical and surgical interventions on olfaction for AwCF. Assessment of olfaction was often limited to subjective and qualitative self-report. We suggest that tracking of olfactory outcomes with psychophysical testing is critical in this population with dietary challenges and weight management issues.

Determining the minimal clinically important difference for the questionnaire of olfactory disorders in people with cystic fibrosis and factors associated with improvement after highly effective modulator therapy.

INTRODUCTION: Olfactory dysfunction (OD) is common among people with cystic fibrosis (PwCF). The Questionnaire of Olfactory Disorders (QOD) is a validated instrument that evaluates olfactory-specific quality-of-life. The QOD minimal clinically important difference (MCID) and factors associated with olfactory improvement after elexacaftor/tezacaftor/ivacaftor have not been determined for PwCF. METHODS: Prospective observational data were pooled from three studies that enrolled adult PwCF with chronic rhinosinusitis (CRS). QOD scores and disease characteristics were assessed. To evaluate internal consistency and calculate the QOD MCID, Cronbach's alpha and four distribution-based methods were employed. For participants who enrolled prior to elexacaftor/tezacaftor/ivacaftor, QOD scores were obtained at baseline and after elexacaftor/tezacaftor/ivacaftor initiation. Multivariable regression was used to identify factors associated with QOD improvement. RESULTS: Of 129 PwCF included, 65 had QOD scores before and 3-6 months after starting elexacaftor/tezacaftor/ivacaftor. Mean baseline QOD score was 6.5 ± 7.9. Mean Cronbach's alpha was ≥0.85. The MCID estimates were as follows: Cohen's effect size = 1.6, standard error of measurement = 2.5, ½ baseline standard deviation = 4.0, and minimal detectable change = 6.9. Mean MCID was 3.7. Of those with pre/post elexacaftor/tezacaftor/ivacaftor QOD scores, the mean change in QOD was -1.3 ± 5.4. After elexacaftor/tezacaftor/ivacaftor, QOD improvement surpassed the MCID in 22% of participants (14/65). Worse baseline QOD scores and nasal polyps were associated with improved QOD scores after elexacaftor/tezacaftor/ivacaftor (both p < 0.04). CONCLUSION: The QOD MCID in PwCF was estimated to be 3.7. Elexacaftor/tezacaftor/ivacaftor led to qualitative but not clinically meaningful improvements in QOD score for most PwCF; PwCF with worse baseline QOD scores and nasal polyps improved in a clinically significant manner.

Olfaction, body mass index, and quality of life with cystic fibrosis combination therapy.

BACKGROUND: Triple-combination therapy of elexacaftor-tezacaftor-ivacaftor (ETI) has been shown to reduce morbidity and mortality in people with cystic fibrosis (PwCF). Although patient body mass index (BMI) favorably increases with ETI treatment, factors contributing to this improvement are poorly characterized. Olfaction contributes to appetite stimulation and anticipation of eating, where higher rates of olfactory impairment (OI) in PwCF may contribute to malnutrition and BMI instability in this population. METHODS: The authors performed a prospective cohort study analyzing 41 CF patient responses to the Cystic Fibrosis Questionnaire-Revised (CFQR) and the 22-Item Sino-Nasal Outcome Test (SNOT-22) and used generalized estimating equations to understand the change in survey variables from being untreated (baseline) to undergoing 3 months of ETI therapy (follow-up). RESULTS: Patients reported significant improvement in their sense of smell at follow-up (p = 0.0036). Their improvements in sense of smell were not confounded by changes in rhinologic or extranasal rhinologic symptoms. Self-reported quality of life (QoL) improved after 3 months of ETI therapy (p = < 0.0001) as did BMI (p = < 0.0001), but improved sense of smell did not independently mediate these changes in QoL and BMI. CONCLUSION: Our results support the impression that ETI therapy improves CF-associated rhinologic symptoms and reverses OI, while contributing to improvement in rhinologic QoL. Sense of smell is not an independent mediator of improved QoL and BMI in this population, suggesting that other factors may have a stronger role in these realms. However, given the subjective improvement in sense of smell, additional evaluation of OI using psychophysical chemosensory assessment will clarify the connection between olfaction, BMI, and QoL in PwCF.

Nutritional considerations for a new era: A CF foundation position paper.

OBJECTIVE: To provide interim advice and considerations to the CF Community around CF nutrition in the current era. METHODS: The Cystic Fibrosis (CF) Foundation organized a multidisciplinary committee to develop a Nutrition Position Paper based on the rapidly changing nutrition landscape in CF, due in part to widespread use of cystic fibrosis transmembrane regulator highly effective modulator therapy (HEMT). Four workgroups were formed: Weight Management, Eating Behavior/Food Insecurity, Salt Homeostasis and Pancreatic Enzyme use. Each workgroup conducted their own focused review of the literature. RESULTS: The committee summarized current understanding of issues pertaining to the four workgroup topics and provided 6 key take-aways around CF Nutrition in the new era. CONCLUSION: People with CF (pwCF) are living longer, particularly with the advent of HEMT. The traditional high fat, high calorie CF diet may have negative nutritional and cardiovascular consequences as pwCF age. Individuals with CF may have poor diet quality, food insecurity, distorted body image, and an higher incidence of eating disorders. An increase in overweight and obesity may lead to new considerations for nutritional management, given potential effects of overnutrition on pulmonary and cardiometabolic parameters.

Complications and Practice Variation in the Use of Peripherally Inserted Central Venous Catheters in People With Cystic Fibrosis: The Prospective Study of Peripherally Inserted Venous Catheters in People With Cystic Fibrosis Study.

BACKGROUND: Peripherally inserted central catheters (PICCs) are used commonly to administer antibiotics to people with cystic fibrosis (CF), but their use can be complicated by venous thrombosis and catheter occlusion. RESEARCH QUESTION: Which participant-, catheter-, and catheter management-level attributes are associated with increased risk of complications of PICCs among people with CF? STUDY DESIGN AND METHODS: This was a prospective observational study of adults and children with CF who received PICCs at 10 CF care centers in the United States. The primary end point was defined as occlusion of the catheter resulting in unplanned removal, symptomatic venous thrombosis in the extremity containing the catheter, or both. Three categories of composite secondary outcomes were identified: difficult line placement, local soft tissue or skin reactions, and catheter malfunction. Data specific to the participant, catheter placement, and catheter management were collected in a centralized database. Risk factors for primary and secondary outcomes were analyzed by multivariate logistic regression. RESULTS: Between June 2018 and July 2021, 157 adults and 103 children older than 6 years with CF had 375 PICCs placed. Patients underwent 4,828 catheter-days of observation. Of the 375 PICCs, 334 (89%) were ≤ 4.5 F, 342 (91%) were single lumen, and 366 (98%) were placed using ultrasound guidance. The primary outcome occurred in 15 PICCs for an event rate of 3.11 per 1,000 catheter-days. No cases of catheter-related bloodstream infection occurred. Other secondary outcomes developed in 147 of 375 catheters (39%). Despite evidence of practice variation, no risk factors for the primary outcome and few risk factors for secondary outcomes were identified. INTERPRETATION: This study affirmed the safety of contemporary approaches to inserting and using PICCs in people with CF. Given the low rate of complications in this study, observations may reflect a widespread shift to selecting smaller-diameter PICCs and using ultrasound to guide their placement.

The gut microbiome, short chain fatty acids, and related metabolites in cystic fibrosis patients with and without colonic adenomas.

BACKGROUND: Adults with cystic fibrosis (CF) are at increased risk for colon cancer. CF patients have reductions in intestinal bacteria that produce short chain fatty acids (SCFAs), although it is unclear whether this corresponds with intestinal SCFA levels and the presence of colonic neoplasia. The aim of this study was to compare gut microbiome and SCFA composition in patients with and without CF, and to assess associations with colonic adenomas. METHODS: Colonic aspirates were obtained from adults with and without CF undergoing colon cancer screening or surveillance colonoscopy. Microbiome characterization was performed by 16S rRNA V3-V4 sequencing. Targeted profiling of SCFAs and related metabolites was performed by LC-MS. RESULTS: 42 patients (21 CF, 21 control) were enrolled. CF patients had significantly reduced alpha diversity and decreased relative abundance of many SCFA-producing taxa. There were no significant differences in SCFA levels in CF patients, although there were reduced levels of branched chain fatty acids (BCFAs) and related metabolites. CF patients with adenomas, but not controls with adenomas, had significantly increased relative abundance of Bacteroides fragilis. CF microbiome composition was significantly associated with isovalerate concentration and the presence of adenomas. CONCLUSIONS: CF patients have marked disturbances in the gut microbiome, and CF patients with adenomas had notably increased relative abundance of B. fragilis, a pathogen known to promote colon cancer. Reductions in BCFAs but not SCFAs were found in CF. Further studies are warranted to evaluate the role of B. fragilis as well the biological significance of reductions in BCFAs in CF.

Trends in and Outcomes of Deliveries Complicated by Cystic Fibrosis.

OBJECTIVE: To characterize current trends and outcomes in pregnancies complicated by cystic fibrosis (CF) that resulted in delivery. METHODS: This repeated cross-sectional study used the U.S. National Inpatient Sample to identify delivery hospitalizations of patients with CF between 2000 and 2019. Trends in delivery hospitalizations of patients with CF were assessed using joinpoint regression to determine the average annual percent change (AAPC). The risk of adverse maternal and obstetric outcomes was compared between patients with and without CF using adjusted logistic regression models accounting for demographic, clinical, and hospital characteristics, with adjusted odds ratios (aORs) with 95% CIs as measures of association. The proportion of patients with CF and other chronic conditions such as pregestational diabetes was analyzed over time. RESULTS: From 2000 to 2019, the prevalence of CF at delivery increased from 2.1 to 10.4 per 100,000 deliveries (AAPC 6.7%, 95% CI 5.7-8.2%). The proportion of patients with CF and other chronic conditions increased from 18.0% to 37.3% (AAPC 3.1%, 95% CI 1.0-5.3%). Patients with CF were more likely to experience severe maternal morbidity (aOR 2.61, 95% CI 1.71-3.97), respiratory complications (aOR 17.45, 95% CI 11.85-25.68), venous thromboembolism (aOR 3.59, 95% CI 1.33-9.69), preterm delivery (aOR 2.15, 95% CI 1.79-2.59), abruption and antepartum hemorrhage (aOR 1.63, 95% CI 1.10-2.41), and gestational diabetes (aOR 2.47, 95% CI 2.47-3.70). CONCLUSION: Although still infrequent (approximately 1 in 10,000), deliveries complicated by CF increased approximately fivefold over the study period. The proportion of patients with CF and other chronic conditions is increasing. Patients with CF are at increased risk for a broad range of adverse outcomes.

Body mass index and additional risk factors for cancer in adults with cystic fibrosis.

BACKGROUND: Adults with cystic fibrosis (CF) have an increased risk of a variety of cancers, notably gastrointestinal cancers. In CF higher body mass index (BMI) is associated with improved long-term outcomes, yet in the general population high BMI is associated with increased cancer risk. We aimed to delineate associations between BMI and other factors with cancer risk in adults with CF. METHODS: This was a retrospective cohort study using CF Foundation Patient Registry data from 1992 to 2015. Data were collected on age, sex, CFTR mutation class, pancreatic insufficiency, and annualized data on BMI and FEV1. The primary analysis was the association between BMI and cancer, with secondary analyses focused on BMI trajectory. Multivariable logistic regression was performed, with analyses stratified by history of transplant. RESULTS: Of 26,199 adults with CF, 446 (1.7%) had cancer diagnosed by histology at a mean age of 40.0 years (SD 12.2), with a higher proportion of transplanted patients developing cancer (137 (3.8%) v 309(1.4%), p < 0.001). Among non-transplanted patients, there was no association between BMI and cancer (p for trend = 0.43). Pancreatic insufficiency (p < 0.01) and higher FEV1 (p < 0.01) were associated with increased cancer risk. In transplanted patients, higher BMI was associated with reduced risk of cancer (p for trend = 0.04). Older age was associated with increased risk in both groups (p < 0.001). BMI trajectories were not associated with cancer risk in either group. CONCLUSION: Higher BMI is associated with a reduced risk of cancer in transplanted adults with CF. Pancreatic insufficiency is a risk factor for cancer in non-transplanted CF patients.

Pharmacokinetics of Gingerols, Shogaols, and Their Metabolites in Asthma Patients.

6-Gingerol and 6-shogaol are the most abundant gingerols and shogaols in ginger root and have been shown to reduce the asthmatic phenotype in murine models of asthma. Several studies have described the pharmacokinetics of gingerols and shogaols in humans following the oral ingestion of ginger, while little was known about the metabolism of these components in humans, particularly in patients with asthma. In this study, a dietary supplement of 1.0 g of ginger root extract was administered to asthma patients twice daily for 56 days and serum samples were drawn at 0.5-8 h on days 0, 28, and 56. The metabolic profiles of gingerols and shogaols in human plasma and the kinetic changes of gingerols, shogaols, and their metabolites in asthma patients collected on the three different visits were analyzed using liquid chromatography-mass spectrometry (LC-MS). Ketone reduction was the major metabolic pathway of both gingerols and shogaols. Gingerdiols were identified as the major metabolites of 6-, 8-, and 10-gingerols. M11 and M9 were identified as the double-bond reduction and both the double-bond and ketone reduction metabolites of 6-shogaol, respectively. Cysteine conjugation was another major metabolic pathway of 6-shogaol in asthma patients, and two cysteine-conjugated 6-shogaol, M1 and M2, were identified as the major metabolites of 6-shogaol. Furthermore, gingerols, shogaols, and their metabolites were quantitated in the human serum collected at different time points during each of the three visits using a very sensitive high-resolution LC-MS method. The results showed that one-third of 6-gingerol was metabolized to produce its reduction metabolites, 6-gingerdiols, and more than 90% of 6-shogaol was metabolized to its phase I and cysteine-conjugated metabolites, suggesting the importance of considering the contribution of these metabolites to the bioavailability and health beneficial effects of gingerols and shogaols. All gingerols, shogaols, and their metabolites reached their peak concentrations in less than 2 h, and their half-lives (t1/2) were from 0.6 to 2.4 h. Furthermore, long-term treatment of ginger supplements, especially after 56 days of treatment, increases the absorption of ginger compounds and their metabolites in asthma patients.

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.

The management of cystic fibrosis chronic rhinosinusitis: An evidenced-based review with recommendations.

BACKGROUND: Cystic fibrosis (CF) chronic rhinosinusitis (CRS) has emerged as a distinct diagnostic entity, unique from other endotypes of CRS in its presentation, pathophysiology, diagnosis, treatment, and outcomes. As the sinonasal health of this patient population may have broad effects on pulmonary health and quality of life, a comprehensive understanding of the diagnostic and therapeutic approach to CF CRS is essential. In recognizing recent scientific advances and unique treatment modalities specific to this challenging patient population, in this review we systematically evaluate the scientific literature and provide an evidenced-based review with recommendations (EBRR) for fundamental management principles of CF CRS. METHODS: A systematic review of the literature was performed. Studies evaluating interventions for the management of CF CRS were included. An iterative review process was implemented in accordance with EBRR guidelines. A treatment recommendation was generated based on an assessment of the benefits, harms, and the overall grade of evidence. RESULTS: We evaluated the published literature on 5 unique topics. Each of the following therapeutic categories was investigated explicitly for treatment outcomes in patients with CF CRS: (1) nasal saline; (2) intranasal corticosteroids (INCS); (3) topical antibiotics; (4) cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapy; and (5) endoscopic sinus surgery (ESS). CONCLUSION: Based on the currently available evidence, nasal saline, ESS, and CFTR modulators are recommended in the management of CF CRS when appropriate. INCS and topical antibiotics are options. Clinical judgment and experience are essential in caring for patients with this uniquely challenging disorder.

The Precision Interventions for Severe and/or Exacerbation-Prone (PrecISE) Asthma Network: An overview of Network organization, procedures, and interventions.

Asthma is a heterogeneous disease, with multiple underlying inflammatory pathways and structural airway abnormalities that impact disease persistence and severity. Recent progress has been made in developing targeted asthma therapeutics, especially for subjects with eosinophilic asthma. However, there is an unmet need for new approaches to treat patients with severe and exacerbation-prone asthma, who contribute disproportionately to disease burden. Extensive deep phenotyping has revealed the heterogeneous nature of severe asthma and identified distinct disease subtypes. A current challenge in the field is to translate new and emerging knowledge about different pathobiologic mechanisms in asthma into patient-specific therapies, with the ultimate goal of modifying the natural history of disease. Here, we describe the Precision Interventions for Severe and/or Exacerbation-Prone Asthma (PrecISE) Network, a groundbreaking collaborative effort of asthma researchers and biostatisticians from around the United States. The PrecISE Network was designed to conduct phase II/proof-of-concept clinical trials of precision interventions in the population with severe asthma, and is supported by the National Heart, Lung, and Blood Institute of the National Institutes of Health. Using an innovative adaptive platform trial design, the PrecISE Network will evaluate up to 6 interventions simultaneously in biomarker-defined subgroups of subjects. We review the development and organizational structure of the PrecISE Network, and choice of interventions being studied. We hope that the PrecISE Network will enhance our understanding of asthma subtypes and accelerate the development of therapeutics for severe asthma.

Trends in and Maternal Outcomes of Delivery Hospitalizations of Patients With an Asthma Diagnosis.

OBJECTIVE: To characterize asthma prevalence and outcomes during U.S. delivery hospitalizations. METHODS: For this repeated cross-sectional analysis, deliveries to women aged 15-54 years with asthma were identified in the 2000-2018 National Inpatient Sample, which approximates a 20% stratified sample of all hospitalizations nationally. Temporal trends in asthma were analyzed using joinpoint regression to estimate the average annual percent change with 95% CIs. The association of asthma with other comorbid conditions was analyzed. The relationship between asthma and several adverse maternal outcomes was analyzed with unadjusted and adjusted logistic regression models, with unadjusted odds ratios and adjusted odds ratios (aORs) as measures of effect. Risk for and trends in a composite of rare, but severe, respiratory complications also were analyzed. RESULTS: An estimated 73,109,790 delivery hospitalizations from 2000 to 2018 were included in the analysis, of which 2,221,644 (3.0%) had a diagnosis of asthma. (Unweighted, the study sample included 15,213,024 deliveries, of which 462,276 [3.0%] had a diagnosis of asthma.) Asthma diagnoses rose from 1.2% in 2000 to 5.3% in 2018, representing an average annual percent change of 8.3% (95% CI 7.4-9.2%). Asthma was more common among women with obesity and chronic hypertension. In adjusted analyses, asthma was associated with severe maternal morbidity (aOR 1.50, 95% CI 1.45-1.55), preeclampsia and gestational hypertension (aOR 1.29, 95% CI 1.26-1.30), postpartum hemorrhage (aOR 1.21, 95% CI 1.19-1.24), cesarean delivery (aOR 1.16, 95% CI 1.15-1.18), gestational diabetes (aOR 1.20, 95% CI 1.18-1.21), venous thromboembolism (aOR 1.79, 95% CI 1.65-1.95), and preterm delivery (aOR 1.27, 95% CI 1.25-1.29). From 2000 to 2018, severe respiratory complications decreased from 72 per 10,000 deliveries with asthma to 14 per 10,000 deliveries with asthma (average annual percent change -9.4%, 95% CI -13.3% to -5.3%). This decreasing risk was offset on a population level by an increase in the risk of asthma. CONCLUSION: Asthma is increasing during deliveries, is associated with adverse maternal outcomes, and is associated with comorbid conditions. Severe respiratory complications are decreasing proportionately among deliveries with asthma, but are stable on a population basis.

Survival in cystic fibrosis after acute respiratory failure supported by extracorporeal membrane oxygenation and/or invasive mechanical ventilation.

BACKGROUND: Despite therapeutic advances, people with cystic fibrosis (CF) develop progressive worsening and exacerbations of their lung disease, which can lead to acute respiratory failure. Historically, survival after mechanical ventilation (MV) has been poor. Outcomes related to use of extracorporeal membrane oxygenation (ECMO) have not been well described in CF. METHODS: We conducted a retrospective analysis of adult patients with CF admitted to the ICU for acute respiratory failure and requiring invasive MV with or without ECMO between July 1, 2006 and June 30, 2016. Separate analysis for the subgroup of MV patients who were eligible for transplant was conducted. RESULTS: Mortality for all patients with respiratory failure requiring advanced support was 37%. Ten of 28 (36%) MV patients, 10 of 26 (38%) ECMO+MV patients and 7 of the 21 (33%) transplant eligible MV patients died. Intensive care unit (ICU) length of stay (LOS) was 24.5±16.6 days for ECMO+MV; 12.9±9.0 days for MV (p=0.001), and 12.3 ±10 days for transplant eligible MV patients (p=0.005 for ECMO+MV comparison). Seven transplant eligible MV patients (33%) and 16 ECMO+MV patients (62%) underwent lung transplantation (p<0.001) during the hospital admission. One and 2-year survival for individuals who survived ICU admission was similar regardless of mode of support. Cox-proportional hazards model did not yield any variables that significantly influenced ICU mortality, 1-year or 2-year mortality. CONCLUSION: Survival for CF patients with acute respiratory failure requiring MV with or without ECMO has improved over time. ECMO may be an appropriate modality for respiratory support in patients with CF and acute respiratory failure who have greater risk of death from MV alone.

Association of Quality of Life Measures and Otolaryngologic Care in Cystic Fibrosis Patients.

OBJECTIVES: Appropriate management of chronic rhinosinusitis (CRS) among patients with cystic fibrosis (CF) is important in improving quality of life. Otolaryngologists play a critical role in reducing CRS symptom burden. This study seeks to evaluate the role of patient-reported quality-of-life measures in guiding interventions for CF-related sinus disease. METHODS: We performed a prospective, cross-sectional study of 105 patients presenting to a CF-accredited clinic between July and September 2018. Demographic data and sinus surgery history were collected, in addition to Sino-Nasal Outcome Test (SNOT-22) and Questionnaire of Olfactory Disorders (QOD-NS) scores. Statistical analysis was conducted using correlation and non-parametric Mann-Whitney U tests. RESULTS: Baseline well-care visits accounted for 71.4% of all clinical evaluations. Prior otolaryngology intervention was noted in 69 (66%) patients, where the majority of these patients (63/69; 91%) underwent endoscopic sinus surgery (ESS). Patients with a history of otolaryngology intervention had an average SNOT-22 score of 33.2 (SD = 20.6) compared to 24.9 (SD = 18.5) for patients without prior intervention (P = .048). The average QOD-NS score was 5.5 (SD = 6.4) among patients referred to otolaryngologists and 3.1 (SD = 5.7) for non-referred patients (P = .012). SNOT-22 and QOD-NS scores were modestly correlated (R of .43). CONCLUSION: CF patients with symptoms resulting in worse quality-of-life assessments were more likely to have established coordinated care with an otolaryngologist. Further validation of the utility of SNOT-22 and QOD-NS questionnaires as care coordination metrics is necessary in the CF population.

The challenge of addressing obesity in people with poorly controlled asthma.

OBJECTIVE: There is a high prevalence of obesity in people with asthma, and obesity is associated with poorly controlled asthma. Significant weight loss might improve asthma control: the purpose of this study was to investigate patient characteristics and factors that might affect implementation of a weight loss and/or roflumilast intervention, to target both obesity and asthma. METHODS: A cross-sectional study of people with obesity and poorly controlled asthma performed at 13 sites across the United States. RESULTS: One hundred and two people participated in this study. Median BMI was 37 (IQR 35-42). The majority, 55%, were African American and 76% were female. Fifty two percent had very poorly controlled asthma. Most participants were quite sedentary (70% reported being inactive or participating only in light-intensity activities according to the Stanford Brief Activity Survey). Participants reported significant impairments related to physical function on the Impact of Weight on Quality of Life-Lite questionnaire (median score 67 [IQR 41-84]). Thirty-five percent of participants reported mild, and 2 % moderate, depressive symptoms as assessed by the Patient Health Questionnaire-9. CONCLUSIONS: Poorly controlled asthma and obesity often affect minority populations and are associated with significant impairments in health related to physical function and low levels of physical activity that might complicate efforts to lose weight. Interventions targeted at poorly controlled asthma associated with obesity in the United States need to address factors complicating health in underserved communities, such as increasing opportunities for physical activity, while also managing activity limitations related to the combination of asthma and obesity.

Health Disparities among adults cared for at an urban cystic fibrosis program.

BACKGROUND: Evidence is conflicting regarding differential health outcomes in racial and ethnic minorities with cystic fibrosis (CF), a rare genetic disease affecting approximately 28,000 Americans. We performed a cross-sectional analysis of health outcomes in Black/Latinx patients compared with non-Hispanic Caucasian patients cared for in a CF center in New York City. Adult patients enrolled in the CF Foundation Patient Registry at the Columbia University Adult CF Program and seen at least once during 2019 were included. Health metrics were compared between Black/Latinx and non-Hispanic Caucasian patients. RESULTS: 262 patients were eligible. 39 patients (15%) identified as Black/Latinx or non-Hispanic Caucasian. Descriptive statistics are reported with mean (standard deviation). Current age was 35.9 (13.3) years for non-Hispanic Caucasian and 32.0 (9.3) years for Black/Latinx patients (p = 0.087). Age of diagnosis did not differ between groups; 9.56 (15.96) years versus 11.59 (15.8) years for non-Hispanic Caucasian versus Black/Latinx respectively (p = 0.464). Pulmonary function, measured as mean forced expiratory volume in one second (FEV1) was 70.6 (22.5) percent predicted in non-Hispanic Caucasian versus 59.50 (27.9) percent predicted in Black/Latinx patients (p = 0.010). Number of visits to the CF clinic were similar between groups. When controlled for age, gender, co-morbidities, median income, and insurance status, there was a continued association between minority status and lower FEV1. CONCLUSIONS: Minorities with CF have significantly lower pulmonary function, the major marker of survival, than non-Hispanic Caucasians, even when controlled for a variety of demographic and socioeconomic factors that are known to affect health status in CF. Significant health disparities based on race and ethnicity exist at a single CF center in New York City, despite apparent similarities in access to guideline based care at an accredited CF Center. This data confirms the importance of design of culturally appropriate preventative and management strategies to better understand how to direct interventions to this vulnerable population with a rare disease.

Combined Liver-Lung-Kidney Transplant in a Patient with Cystic Fibrosis.

BACKGROUND Individuals with cystic fibrosis (CF) constituted approximately 10% of organ transplants in 2019, with the majority of transplants consisting of bilateral lung transplant. Multiorgan transplantation in individuals with cystic fibrosis (CF) is rare, and usually involves the liver and lung combined. Since kidney disease is not a common sequela of CF, the need for renal transplant in individuals who have not previously undergone lung transplant is uncommon. CASE REPORT We report a case of successful liver-lung-kidney transplant in a 23-year-old man with CF-related liver and lung disease, who developed renal failure due to IgA nephropathy. He required renal replacement therapy during the months before transplantation. After discussions among the liver, lung, and renal transplant teams, the patient was listed for multiorgan transplantation. An appropriate single donor for all organs was identified, and the patient underwent transplantation. The patient required extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT) perioperatively, with total operative time of 23 h and 1 min. Postoperative course was notable for hemothorax and medication-induced acute tubular necrosis, which resolved without the need for renal replacement therapy. Liver and lung graft function was normal at 6 months, and renal function was minimally reduced. CONCLUSIONS Triple organ transplantation in CF is a viable option for individuals with multiorgan failure who may otherwise not qualify for single/dual organ transplantation. Use of ECMO and CRRT can be necessary during the long operative procedure. Optimal immunosuppression protocols for this group of patients has not yet been established, and ethical concerns regarding multiorgan transplantation exist.
