Determinants of quality of life in children with asthma.

BACKGROUND: HRQoL in children with asthma depends on multiple factors, among which asthma severity and level of control are believed to play a vital role. The determinants of the connection between asthma severity and asthma control with quality of life remain unclear. AIMS: Primary aim of the study was to evaluate the HRQoL in children with asthma and to determine the factors that affect it. MATERIALS AND METHODS: In total 504 children and one of their parents were recruited during a regular follow up visit in an outpatient asthma clinic. The measures used were the DISABKIDS smiley measure (DSmM), chronic generic measure-long form (DCGM-37) and the Condition-specific modules for asthma along with a special form for collecting demographic and clinical characteristics. RESULTS: Three hundred fifteen children with mean age 5.35 years (Group A) and 189 with mean age 10.79 years (Group B), were recruited. Children with controlled asthma had significant higher mean score than the other asthma control groups (P < 0.001). Corticosteroid use, asthma severity, number of visits in doctor's office and lack of asthma control were significantly associated with the DCGM-37 scores as well as Impact Scale and Worry Scale. Lack of Asthma Control was the only factor that was associated with negative HRQoL in all the multiple regression models, controlling for the effect of the other covariates, in both age groups. CONCLUSIONS: In conclusion, the evaluation of asthma HRQoL independently reflects the asthma control state and a dimension of its severity. These results highlight the need to modify asthma management strategy.

Level of parent-asthmatic child agreement on health-related quality of life.

BACKGROUND: Direct assessment of health-related quality of life (HRQοL) is necessary to understand the impact of a disease on patients' well-being and to evaluate clinical interventions. There is substantial debate in the literature on pediatric health outcomes concerning who is the most appropriate respondent when assessing children's HRQoL. OBJECTIVE: To evaluate the level of agreement between child self-reports and parent proxy-reports concerning HRQoL in children with asthma. METHODS: A total of 504 children with asthma and their parents who were referred to outpatient asthma clinic participated in this study. Subjects were divided into two age groups (4-7- and 8-14-year-olds). The DISABKIDS chronic generic measure-long form (DCGM-37), the DISABKIDS smiley measure (DSM), and the DISABKIDS condition-specific modules for asthma were used. The level of agreement between children and parents was evaluated using intra-class correlation coefficients and Bland-Altman analysis. RESULTS: A satisfactory level of agreement between younger children and their parents except those with severe asthma with both methods was observed; the level of agreement in the older ones was moderate with the exception of general subscale. Asthmatic children's mean HRQoL scores were significantly lower than their parents for all subscales, except children with severe asthma in the older group, who stated lower HRQoL than their parents in most of the domains except those of Impact and Worry that were in close agreement. Fathers' assessment of HRQoL score was closer to their children's self-assessment in both groups. Families with higher family income showed a greater level of agreement. CONCLUSIONS: Our study illustrated that parents overestimate HRQoL of their children with asthma even though moderate agreement between child self-reports and parent proxy-reports on HRQoL was noticed. Fathers seem to be better proxy-reporters than mothers. Any evaluation of current approaches to measuring children's HRQoL needs to allow both parent and child to give their own perspective.

Aspergillus and the paediatric lung.

Aspergillus spp produce a wide range of saprophytic and invasive syndromes in the lungs, including allergic bronchopulmonary aspergillosis (ABPA), aspergilloma and invasive pulmonary aspergillosis (IPA). ABPA results from hypersensitivity to the fungus, and mainly affects patients with asthma or cystic fibrosis (CF). The treatment of choice consists of systemic corticosteroids and itraconazole. Aspergilloma is managed by observation or surgery. IPA is predominantly seen in patients with haematological malignancies, chronic granulomatous disease or immunosuppressive treatment. With the use of aggressive therapies for end-stage CF, such as heart-lung transplantation, the potential for a patient to convert from colonization or ABPA to IPA has increased. Suggestive clinical and radiological findings, supplemented with mycological data using serology and molecular biology, have enhanced the capacity to diagnose IPA in paediatric patients. While voriconazole is considered the first-line therapy in IPA, several other antifungal agents may be appropriate alternatives.

Cough affects quality of life in asthmatic children aged 8-14 more than other asthma symptoms.

BACKGROUND: Asthma may influence children's health-related quality of life (QoL) differently by various symptoms, at different severity. The primary aim of this study was to evaluate the QoL in children with asthma and describe the impact of each asthma symptom on the child's well-being at different severity levels. MATERIAL AND METHODS: Two hundred randomly selected children and one of their parents who consulted an outpatient asthma clinic, participated in the study. Qol was assessed with DISABKIDS-Smiley measure for children aged 4-7 years and with DISABKIDS DCGM-37 and Asthma Module for children 8-14 year old. RESULTS: Most of the children suffered from mild or moderate persistent asthma. Children with uncontrolled asthma stated lower QoL compared to partly controlled or controlled in both age groups (p < 0.05 in all domains). Cough appeared to affect QoL of 8-14 year olds more than other symptoms, especially in girls. In younger children, sex (boys, p = 0.039), age (p = 0.045), proxy sex (father, p = 0.048), frequency of doctor visits (4-6 months, p = 0.001), use of beta-2 agonists (p = 0.007) and father's smoking habits (p = 0.015) were associated with the QoL of coughing children but no correlation between cough and QoL was detected. In the 8-14 year age group coughers reported lower QoL compared to their counterparts; moreover, cough was found to affect QoL more than other symptoms (p < 0.05 in all domains). CONCLUSIONS: Cough has a direct effect on asthmatic children's QoL but there is still an obvious need for research to reveal all the determinats of this effect.

Atypical CT findings of isolated pulmonary Langerhans cell histiocytosis in a 4-year-old boy.

A 4-year old boy was admitted to hospital with progressive respiratory failure. A chest roentgenogram revealed hyperinflated lungs and a diffuse reticular pattern. There was no smoking history in the family environment. A thin slice computed tomography of the lungs exhibited extended and diffuse cystic lung disease with no zonal predominance. An open lung biopsy showed pulmonary Langerhans cell histiocytosis. No other organs were involved. Despite treatment initiation the boy succumbed to his pulmonary insufficiency 3 weeks later. Isolated pulmonary Langerhans cell histiocytosis in children may have an unfavorable prognosis and in contrast with adults, it may present on computed tomography with lower lobe predominance and without sparing the lung bases or the anterior parts of middle lobe and lingula.
