Staphylococcus aureus with decreased susceptibility to glycopeptides in cystic fibrosis patients

AbstractWe report the isolation of Staphylococcus aureus with decreased susceptibility to glycopeptides in five CF patients and review the clinical and microbiological features of these cases. Three patients presented with pulmonary exacerbation that may be attributed to these strains and two of them were successfully treated using linezolid therapy. Glycopeptide-intermediate S. aureus (GISA) strains isolated in two patients were susceptible to methicillin, while the three other patients harbored methicillin-resistant GISA. Rarely reported in CF, GISA may remain underestimated due to the difficulty of detection, and both clinicians and microbiologists should be aware of the GISA emergence in CF patients’ population

Non-classic cystic fibrosis associated with D1152HCFTR mutation

Background: Limited knowledge exists on phenotypes associated with the D1152H cystic fibrosis transmembrane conductance regulator (CFTR) mutation. Methods: Subjects with a D1152H allele in trans with another CFTR mutation were identified using the French Cystic Fibrosis Registry. Phenotypic characteristics were compared with those of pancreatic insufficient (PI) and pancreatic sufficient (PS) cystic fibrosis (CF) subjects in the Registry (CF cohort). Results: Forty‐two subjects with D1152H alleles were identified. Features leading to diagnosis included chronic sinopulmonary disease (n = 25), congenital absence of the vas deferens (n = 11), systematic neonatal screening (n = 4), and genetic counseling (n = 2). Median age at diagnosis was 33 [interquartile range (IQR, 24–41)] years in D1152H subjects. Median sweat chloride concentrations were 43.5 (39–63) mmol/l in D1152H subjects and were markedly lower than in PI and PS CF subjects (p < 0.05). Bronchiectasis was present in 67% of D1152H subjects, but Pseudomonas aeruginosa colonization and pancreatic insufficiency were present in <30% of subjects. Estimated rates of decline in forced expiratory volume in 1 s (FEV1) were lower in D1152H subjects vs PI CF subjects (p < 0.05). None of the D1152H subjects identified since 1999 had died or required lung transplantation. Conclusions: When present in trans with a CF‐causing mutation, D1152H causes significant pulmonary disease, but all subjects had prolonged survival
