Haematopoietic stem cell transplantation for mucopolysaccharidosis type VII: A case report

Mucopolysaccharidosis type VII (MPS VII) is an inherited disease characterized by the cellular accumulation of undegraded GAGs due to the deficiency of the lysosomal enzyme β-glucuronidase. We describe a case of a 2-year-old female affected by a moderate form of MPS VII and submitted twice to HSCT with the aim of stabilizing skeletal problems and preventing neurocognitive alterations. The child underwent a second transplantation due to the rejection of the graft after a reduced-intensity conditioning in the first transplant. A myeloablative regimen allowed to achieve a stable full donor engraftment and normal enzyme levels during the 6 years of follow-up. Clinically, we observed stabilization of skeletal deformities and normal neurocognitive development. This is one of the few reports of mucopolysaccharidosis type VII treated with allogeneic HSCT.

Health-related quality of life compared with cardiopulmonary exercise testing at the midterm follow-up visit after tetralogy of Fallot repair: a study of the German competence network for congenital heart defects

This nationwide study aimed to evaluate health-related quality of life (QoL) experienced by children after tetralogy of Fallot repair and to compare self-reported physical ability with objective exercise performance. This prospective nonrandomized, government-funded multicenter study enrolled 168 patients (70 girls; ages 8-16 years) after tetralogy of Fallot repair at eight German heart centers. Health-related QoL was analyzed by the self-reported KINDL-R quality-of-life questionnaire. The patients' actual exercise capacity was evaluated by a cardiopulmonary exercise test. Health-related QoL and cardiopulmonary exercise capacity were compared with those of an age-matched German standard population. Correlation of health-related QoL with self-estimated physical rating and cardiopulmonary exercise capacity were analyzed. Health-related QoL in children and adolescents after tetralogy of Fallot repair is without limitation. Compared with the standard population, all the items evaluated by the KINDL-R questionnaire showed better or similar values, whereas objective exercise capacity compared with that of the standard population was impaired. Peak oxygen uptake correlated significantly with the physical well-being (p = 0.002) and the total score (p = 0.01) of the KINDL-R questionnaire. Health-related QoL experienced by children and adolescents after tetralogy of Fallot repair is comparable with that of the healthy standard population. However, closer inspection shows that self-estimated physical functioning is significantly overestimated compared with actual exercise capacity. Quality-of-life instruments and exercise tests, therefore, should be used in a complementary manner with children to avoid eventually fatal misinterpretation of patient-estimated physical ability.

Evaluation of quality of life among the caregivers of asthmatic children: the new IFABI-R questionnaire

BACKGROUND

The health-related quality of life (HRQoL) of asthmatic children and their caregivers is correlated to management of the disease and the presence of certain morbidity indicators. The integral assessment of paediatric asthma must include the evaluation of HRQoL among the caregivers, although existing questionnaires only partially assess the dimensions of this aspect. The present study describes a new questionnaire for evaluating HRQoL among the caregivers, comprising three dimensions (functional, emotional, and socio-occupational).

MATERIAL AND METHODS

The study involves two phases. A total of 81 patients between 3 and 9 years of age and their caregivers participated in the first phase, involving a qualitative and psychometric study of the preliminary version of the questionnaire (IFABI). A total of 137 patients between 2 and 17 years of age and their caregivers participated in the second phase, in which the revised version of the questionnaire (IFABI-R) was developed and subjected to psychometric evaluation.

RESULTS

First phase: The IFABI showed important reliability and internal consistency (Cronbach alpha=0.93), concurrent validity requiring improvement, and a scantly clear internal structure. Second phase: The IFABI-R showed important reliability and internal consistency (Cronbach alpha=0.90), adequate concurrent validity, and a three-dimensional structure whose three factors correspond to the three dimensions of the questionnaire.

CONCLUSIONS

The good psychometric results obtained with the IFABI-R justify its use in paediatric asthmatic patients. The questionnaire is currently being scaled, and its sensitivity to change is being assessed.

Quality of life in school-age children with orofacial clefts and their families

Nonsyndromic orofacial clefts might affect family functioning and probably reduce the quality of life in school-age children and their parents. One hundred seventy consecutive children with orofacial clefts between 8 and 12 years and their families were asked to answer the Impact on Family Scale and KINDL. The results were compared with the quality of life in an age- and sex-matched group of unaffected schoolchildren. One hundred thirty-two families participated in this study. Family functioning was found superior in families with children with cleft lip than in families with children with cleft palate only or cleft lip and palate. Sex had no significant influence on family functioning. The quality of life in schoolchildren with orofacial clefts was found superior to the control group. Reductions were observed in children with cleft lip and palate in the dimensions "family" and "friends," indicating problems in the social field. Boys with orofacial clefts experienced a lower quality of life than girls. Children with cleft lip and palate and cleft palate only experienced a lower quality of life than children with cleft lip. Even years after successful cleft reconstruction, coping and mastering the diagnosis of orofacial cleft is a relevant concern for affected families. Several limitations of the quality of life in schoolchildren were identified, mostly affecting their social role.

Quality of life and family functioning in children with nonsyndromic orofacial clefts at preschool ages

Children with orofacial clefts (OFC) at preschool ages may have to tolerate psychosocial disadvantages due to their altered speech and facial appearance probably affecting their quality of life (QoL) and family functioning. In 147 children with OFC aged between 5 and 6 years and their families, the QoL and family functioning were analyzed using the KINDL questionnaire for measuring health-related QoL in children and impact on family scale. The KINDL scores were lowest in the dimension self-esteem. In all dimensions, the KINDL scores of children were higher than those of the parents suggesting a superior QoL than the caregivers estimated (P<0.001). In affected families, the impact on family scale dimensions personal impact and impact on coping strategies were found highest. Families having children with isolated cleft lip or cleft lip and palate had higher impacts on coping strategies when compared with children having isolated cleft palate (P<0.041). The impact for siblings (P<0.02) was found highest in patients with cleft lip and palate. In all examined dimensions, children with OFC perceived a higher QoL than their caregivers expected. However, self-esteem seems to be problematic in all types of OFC and in both genders. Knowledge of potential impacts related to the type of cleft and the gender of the patient will probably facilitate health care professionals to identify children and families at high risk to experience a reduced QoL and may help to offer specific support and treatment strategies.

Health-related Quality of Life in Preschool Children with Wheezing and Dyspnea: Preliminary Results from a Random General Population Sample

Respiratory symptoms have a high prevalence among preschool children (5-20%). This study evaluated the impact of parent-reported respiratory symptoms on health-related quality of life (HRQOL) using the TNO-AZL Preschool Children Quality of Life (TAPQOL) questionnaire. A random general population sample of 500 parents of 3-46-month old children was mailed a questionnaire containing the TAPQOL and questions on the prevalence of respiratory symptoms. The impact of respiratory symptoms on HRQOL was analysed using the Mann-Whitney test and linear regression analysis. Response rate was 83%. The prevalence of combined "wheezing and dyspnea" during the past 4 weeks was 10%. For the sleeping, appetite, lung problems, skin problems, communication, and positive mood TAPQOL scales, HRQOL was significantly lower in the subgroup with "wheezing and dyspnea" (n = 41) than in the subgroup without symptoms (n = 321); large effect sizes were observed for lung problems (2.06) and sleeping (0.80). In multivariate analysis, adjusted for age and gender of the child, "wheezing and dyspnea" were associated with the scales sleeping, appetite, lung problems, communication, and positive mood (p < 0.05). In conclusion, decreases in HRQOL among preschoolers with parent-reported respiratory symptoms are measurable with the TAPQOL. We recommend studying the impact of doctor-diagnosed respiratory symptoms on HRQOL in future studies.
