With the growing class of CFTR modulator therapy available to more patients and with increasing pregnancies in individuals with CF, there is a growing need to understand the effects of these agents during pregnancy. There are few reports of their continued use in the literature, although it is likely that this is not an uncommon occurrence. We report the uncomplicated and successful pregnancy of a woman treated with lumacaftor/ivacaftor, as well as the clinical course of the infant during the first 9 months of life. We also report drug levels in plasma from the mother, cord blood, breast milk, and infant to estimate fetal and infant drug exposure.

In both phase III studies of LUM/IVA, as well as an extension study, worsening of mental health was not reported as a common side effect. Here we describe five cases in adolescent female patients that suggest a worsening of anxiety or depression associated with its use. In these five patients, two experienced suicidal ideation and three made suicide attempts that resulted in psychiatric hospitalizations.

Objective To determine the incidence of acute kidney injury (AKI) in infants exposed to nephrotoxic drug combinations admitted to 268 neonatal intensive care units managed by the Pediatrix Medical Group. Study designWe included infants born at 22-36 weeks gestational age, £120 days postnatal age, exposed to nephrotoxic drug combinations, with serum creatinine measurements available, and discharged between 2007 and 2016. To identify risk factors associated with a serum creatinine definition of AKI based on the Kidney Disease: Improving Global Outcomes criteria, we performed multivariable logistic and Cox regression adjusting for gestational age, sex, birth weight, postnatal age, race/ethnicity, sepsis, respiratory distress syndrome, baseline serum creatinine, and duration of combination drug exposure. The adjusted odds of AKI were determined relative to gentamicin + indomethacin for the following nephrotoxic drug combinations: chlorothiazide + ibuprofen; chlorothiazide + indomethacin; furosemide + gentamicin; furosemide + ibuprofen; furosemide + tobramycin; ibuprofen + spironolactone; and vancomycin + piperacillin-tazobactam.Results Among 8286 included infants, 1384 (17%) experienced AKI. On multivariable analysis, sepsis, lower baseline creatinine, and duration of combination therapy were associated with increased odds of AKI. Furosemide + tobramycin and vancomycin + piperacillin-tazobactam were associated with a decreased risk of AKI relative to gentamicin + indomethacin in both the multivariable and Cox regression models.Conclusions In this cohort, infants receiving longer durations of nephrotoxic combination therapy had an increased odds of developing AKI.

Background: Cystic fibrosis (CF) is a multisystem disease that often requires otolaryngology care. Individuals with CF commonly have chronic rhinosinusitis but also present with hearing loss and dysphonia. Given these manifestations of CF, otolaryngologists are frequently involved in the care of patients with CF; however, there is limited consensus on optimal management of sinonasal, otologic, and laryngologic symptoms. Methods:The Cystic Fibrosis Foundation convened a multidisciplinary team of otolaryngologists, pulmonologists, audiologists, pharmacists, a social worker, a nurse coordinator, a respiratory therapist, two adults with CF, and a caregiver of a child with CF to develop consensus recommendations. Workgroups developed draft recommendation statements based on a systematic literature review, and a ≥80% consensus was required for acceptance of each recommendation statement. Results:The committee voted on 25 statements. Eleven statements were adopted recommending a treatment or intervention, while five statements were formulated recommending against a specific treatment or intervention. The committee recommended eight statements as an option for select patients in certain circumstances, and one statement did not reach consensus. Conclusion: These multidisciplinary consensus recommendations will help providers navigate decisions related to otolaryngology consultation, medical and surgical management of CF-CRS, hearing, and voice in individuals with CF. A collaborative and multidisciplinary approach is advocated to best care for our patients with CF. Future clinical research is needed utilizing standardized, validated outcomes with comprehensive reporting of patient outcome, effects of modulator therapies, and genetic characteristics to help continue to advance care, decrease morbidity, and improve the quality of life for individuals with CF.

OBJECTIVE Cystic fibrosis (CF) patients and caregivers are impacted by the number of pharmacological agents and unique administration needs; however, no data currently assesses how medication regimen complexity impacts clinical outcomes in this population. The objective of this study is to evaluate if an association exists between increased medication regimen complexity and clinical endpoints in pediatric patients with CF. METHODS This retrospective analysis included all pediatric patients with CF (ages 5–20 years) with at least 2 pharmacist encounters and acceptable pulmonary function tests at our pediatric pulmonary clinic during 2017. Each patient's medication regimen was scored using the validated Medication Regimen Complexity Index (MRCI) tool. The primary outcome was the correlation between MRCI score and lung function. Secondary endpoints included growth, number of infections requiring antibiotics, and hospitalizations. RESULTS MRCI scores of the 113 included patients ranged from 2 to 101 points. A negative correlation was found between initial and final MRCI score and initial and final forced expiratory volume in 1 second (FEV1; r = −0.323, p = 0.0005 and r = −0.287, p = 0.0021, respectively). MRCI scores were negatively correlated with BMI percentile for both encounters (r = −0.162 and r = −0.125) but were not significant. Higher MRCI scores were associated with increased use of oral and intravenous antibiotics and hospital admissions. CONCLUSIONS Higher MRCI scores are correlated with a significant decrease in FEV1, increased need for antibiotic therapy, and more hospital admissions in pediatric patients with CF. Larger studies are needed to determine if a correlation exists between MRCI score and growth.
