Background: Chronic pulmonary infection is the leading cause of mortality and morbidity in patients with cystic fibrosis (CF). The most common pathogens isolated in CF are Staphylococcus aureus and Pseudomonas aeruginosa (P. aeruginosa). Chronic infection of P. aeruginosa and MRSA are associated with worse survival and antibiotic eradication treatment is recommended for both. This study evaluates the efficacy of intravenous (IV) vs. non-IV antibiotics in the eradication of P. aeruginosa and MRSA. Methods: This was a single-center retrospective study at a large CF center. All respiratory specimen cultures of 309 CF patients and eradication regimens between 2015-2019 were reviewed. The primary analysis was the comparison of the percentage of successful eradication after receiving IV and non-IV eradication regimens. Demographic and clinical risk factors for eradication failure were also analyzed. Results: 102 patients with P. aeruginosa isolations and 48 patients with MRSA were analyzed. At one year, 21.6% in P. aeruginosa group and 35.4% in MRSA group were successfully eradicated. There was not any statistically significant difference between IV vs. non-IV antibiotic regimens on eradication in either group. Additionally, none of the clinical risk factors was significantly associated with eradication failure in P. aeruginosa and MRSA groups. Conclusion: In the eradication of P. aeruginosa and MRSA, IV and non-IV treatment regimens did not show any superiority to one another. Non-parenteral eradication could be a better option in eradication considering the cost-effectiveness and the treatment burden of IV treatments due to hospitalization and the need for IV access.

Background: Depression and anxiety symptoms in patients with cystic fibrosis (CF) and their caregivers are 2-3 times higher than in the normal population. This study aims to evaluate the frequency and severity of depression and anxiety symptoms and to determine possible risk factors in CF patients and their mother and/or fathers at Marmara University CF center. Methods: The study included 132 CF patients who were followed up at our CF center. Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Questionnaire (GAD-7) were used to screen depression and anxiety. The questionnaires were completed by 50 CF patients (aged 12 - 17 years) and 132 parents of patients (aged 0-17 years). Results: While moderate to severe depression were seen in 25.5% of patients, 33.7% of mothers and 14.6% of fathers; moderate to severe anxiety were present in 17.6%, 21.8% and 8.5%, respectively. None of the demographic characteristics was identified as a predictor of depression or anxiety. GAD-7 scores have shown a higher incidence of anxiety in mothers of patients with chronic methicillin-resistant Staphylococcus Aureus (p = 0.034). Additionally, hospitalization in the last 12 months was statistically significantly higher in PHQ-9 scores of fathers (p = 0.043). Analysis of patients’ adherence to medical treatment and airway clearance showed higher depression and anxiety in mothers of the non-adherent group (p = 0.002). Conclusion: Depression and anxiety were common in CF patients and their parents. These results illustrate the importance of depression/anxiety screening and psychosocial support for the CF patient and their parents.
