Human Papilloma Virus Vaccination Among Female Patients Attending French Pediatric Cystic Fibrosis Centers.

STUDY OBJECTIVE: To describe human papilloma virus (HPV) vaccination practice among adolescent girls with cystic fibrosis (CF) and to identify reasons for non-vaccination. DESIGN: Cross-sectional multicentric study. SETTING AND PARTICIPANTS: Girls aged 9-17 years, attending 7 French pediatric CF centers, and their accompanying adult. INTERVENTIONS: Administration of a self-report questionnaire. MAIN OUTCOME MEASURES: The proportion of girls having received or receiving HPV vaccination, compliance with the vaccination schedule, factors associated with vaccination, and reasons for vaccination and for non-vaccination. RESULTS: A total of 113 girls and 104 accompanying adults participated. The mean age was 13.6 years (standard deviation 2.5; range 9-17). A total of 34 (30.9%) patients reported having received HPV vaccination. Among the 34 girls aged 15 years or older, 15 (44.1%) were vaccinated. Most patients (58.8%) started vaccination between 11 and 14 years of age (mean age 13.9). Most vaccine prescriptions (67.6%) were made by a CF center health care provider. Factors associated with vaccination were older age (odds ratio [OR] = 1.27, 95% confidence interval [CI] = 1.01-1.6, P = .037 for each year older), previous vaccination by the accompanying parent of one of their children for hepatitis B (OR = 8.01, 95% CI = 0.96-67.02), P = .055), and parental influence on decision-making (OR = 2.77, 95% CI = 0.97-7.95, P = .058). Health care providers' positive advice and fear of HPV-related disease were the main reasons given to justify vaccination decisions. Insufficient knowledge and concerns about potential side effects were the main barriers. CONCLUSION: HPV vaccination remains insufficient among girls with CF. CF health care providers may play a crucial role in HPV vaccination acceptance, and their sensitization to cervical cancer prevention is mandatory.

Glucose trajectories in cystic fibrosis and their association with pulmonary function.

BACKGROUND: The prevalence of cystic fibrosis-related diabetes is increasing. This condition is potentially responsible for respiratory decline. METHODS: At inclusion, then yearly (over three years), 111 children and 117 adults with cystic fibrosis had oral glucose tolerance and insulin tests at one (G1) and 2h (G2). KmL analysis identified homogeneous G1 and G2 glucose trajectories. A linear mixed model quantified the relationships between trajectories and FEV1 changes. RESULTS: In children, there were three G1 and four G2 trajectories and FEV1 decrease was not significantly different between G1 or G2 trajectories. In adults, two G1 and four G2 trajectories were identified and FEV1 change was estimated at -0.85/year (95% CI: [-1.54; -0.17], p=0.01) whatever the G1 trajectory and found significantly faster in the high and increasing G2 trajectory (-2.1/year, [-3.9; -0.2], p=0.03). CONCLUSIONS: In case of persistent G2 abnormality, physicians should be alert for clinical deterioration and intensify patient surveillance.
