Mid-term health-related quality of life in community-acquired bacterial meningitis survivors; the COMBAT study.

BACKGROUND: Community Acute Bacterial Meningitis (CABM) is a rare infectious disease leading to important impairments. Our aim was to describe CABM survivors' quality of life (QOL) 12 months post-CABM and to assess its associations with CABM sequelae. METHODS: Patients included in the CABM COMBAT cohort were evaluated one year after the CABM episode. Data were collected by questionnaire, via phone calls with the patients. The WHOQOL-BREF was used to measure CABM survivors' QOL. Hierarchical multivariate linear regressions were performed. RESULTS: Study population was composed of 284 patients. At 12 months, 53.9% (153/284) reported at least incident headache/worsening headache intensity at 12 months post-CABM, and/or incident hearing impairment, and/or unfavourable disability outcome (GOS). Unfavourable disability outcome was associated with lower physical health QOL (B = -30.35, p<0.001), lower mental health QOL (B = -15.31, p<0.001), lower environmental QOL (B = -11.08, p<0.001) and lower social relationships QOL (B = -9.62, p<0.001). Incident headache/worsening headache since meningitis onset was associated with lower psychological health (B = -5.62, p = 0.010). Incident hearing impairment was associated with lower physical QOL (B = -5.34, p = 0.030). Hierarchical regressions showed that CABM impairments significantly increase explanatory power of multivariate models (for physical health R2 change = 0.42, p<0.001, for psychological health R2 change = 0.23, p<0.001, for social relationships R2 change = 0.06, p<0.001 and for environment domain R2 change was 0.15, p<0.001). CONCLUSIONS: 12 month-CABM burden is heavy. Early detection and management of CABM impairments should be performed in clinical practice as early as possible to optimize patients' psychological and psychosocial functioning. CLINICALTRIAL.

Pneumocystis jirovecii in the air surrounding patients with Pneumocystis pulmonary colonization.

In this study, Pneumocystis jirovecii was detected and characterized in the air surrounding patients with Pneumocystis pulmonary colonization. Air samples were collected in the rooms of 10 colonized patients using Coriolis® µ air sampler at 1m and 5m from the patient's head. P. jirovecii DNA was amplified and genotyped in pulmonary and air samples at the mitochondrial large subunit ribosomal RNA gene. P. jirovecii DNA was detected in 5 of the 10 air samples collected at 1m and in 5 of the 10 other air samples collected at 5m. P. jirovecii genotyping was successful in 4 pairs or triplets of air and pulmonary samples. Full genotype matches were observed in 3 of the 4 pairs or triplets of air and pulmonary samples. These results provide original data supporting P. jirovecii exhalation from colonized patients and emphasize the risk of P. jirovecii nosocomial transmission from this patient population.
