Quality of life in children with non-cystic-fibrosis bronchiectasis

Non-cystic-fibrosis bronchiectasis (non-CF BE) continues to be a problem in developing countries and it is therefore important to examine and assess this disease.

The aims of this prospective study were to evaluate the health-related quality of life (HRQOL) in non-CF BE children and also to assess the risk factors associated with HRQOL.

Forty-two non-CF BE patients between the ages of 9 and 18 years were enrolled in the study. All recruited patients completed the generic Short-Form-36 (SF-36), the St. George's Respiratory Questionnaire (SGRQ) for disease-specific QOL scale and forms on socioeconomic status (SES). The extent and severity of CT abnormalities were evaluated by using the modified Bhalla scoring system. Association between HRQOL questionnaires and demographic variables, pulmonary function test, high-resolution CT scores and SES were evaluated.

SF-36 and SGRQ subscales all correlated inversely with each other (SF-36 physical component summary with SGRQ symptoms score: r = -0.466, p = 0.001, activity score: r = -0.666, p = 0.000 and impact score: r = -0.667, p = 0.000. SF-36 mental component summary with SGRQ symptoms score: r = -0.396, p = 0.005, activity score: r = -0.533, p = 0.000 and impact score: r = -0.512, p = 0.000). There was an inverse correlation between SGRQ symptoms scores and the duration of regular follow-up (r = -0.3, p = 0.04). The symptoms subscale of SGRQ correlated positively with low values for pulmonary function testing (r = -0.417, p = 0.003) and frequent antibiotic requirements (r = 0.303, p = 0.035).

Early diagnosis and regular follow-up of children with non-CF BE is important for improving their QOL. As expected, the severity and frequency of symptoms are inversely related to the pulmonary function and the QOL scores. A disease-specific questionnaire should be developed to monitor QOL in children with non-CF BE.
