Abstract

To evaluate pulmonary function and functional capacity in children and adolescents with sickle cell disease. This was a cross-sectional study involving 70 children and adolescents (8-15 years of age) with sickle cell disease who underwent pulmonary function tests (spirometry) and functional capacity testing (six-minute walk test). The results of the pulmonary function tests were compared with variables related to the severity of sickle cell disease and history of asthma and of acute chest syndrome. Of the 64 patients who underwent spirometry, 15 (23.4%) showed abnormal results: restrictive lung disease, in 8 (12.5%); and obstructive lung disease, in 7 (10.9%). Of the 69 patients who underwent the six-minute walk test, 18 (26.1%) showed abnormal results regarding the six-minute walk distance as a percentage of the predicted value for age, and there was a ≥ 3% decrease in SpO2 in 36 patients (52.2%). Abnormal pulmonary function was not significantly associated with any of the other variables studied, except for hypoxemia and restrictive lung disease. In this sample of children and adolescents with sickle cell disease, there was a significant prevalence of abnormal pulmonary function. The high prevalence of respiratory disorders suggests the need for a closer look at the lung function of this population, in childhood and thereafter. Avaliar a função pulmonar e a capacidade funcional em crianças e adolescentes com doença falciforme. Estudo transversal com 70 crianças e adolescentes com doença falciforme (8-15 anos), submetidos a testes de função respiratória (espirometria) e de capacidade funcional (teste de caminhada de seis minutos). Os resultados da avaliação da função pulmonar foram comparados com variáveis relacionadas à gravidade da doença falciforme e à presença de história de asma e de síndrome torácica aguda. Dos 64 pacientes submetidos à espirometria, 15 (23,4%) apresentaram resultados alterados: distúrbio ventilatório restritivo, em 8; (12,5%) e distúrbio respiratório obstrutivo, em 7 (10,9%). Dos 69 pacientes submetidos ao teste de caminhada de seis minutos, 18 (26,1%) apresentaram resultados alterados na distância em % do previsto para a idade, e houve uma queda ≥ 3% na SpO2 em 36 (52,2%) dos pacientes. Não houve associações significativas entre função pulmonar alterada e as outras variáveis analisadas, exceto para hipoxemia e distúrbio ventilatório restritivo. Observou-se uma significativa prevalência de alterações na função pulmonar nesta amostra de crianças e adolescentes com doença falciforme. A elevada prevalência de distúrbios ventilatórios sugere a necessidade de um olhar mais atento à função pulmonar desde a infância nessa população.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 September 2017.
All research outputs
#9,344,125
of 11,689,928 outputs
Outputs from Jornal Brasileiro de Pneumologia
#138
of 256 outputs
Outputs of similar age
#192,963
of 263,738 outputs
Outputs of similar age from Jornal Brasileiro de Pneumologia
#1
of 4 outputs
Altmetric has tracked 11,689,928 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 256 research outputs from this source. They receive a mean Attention Score of 1.4. This one is in the 26th percentile – i.e., 26% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 263,738 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
