There was association between the quality of life of patients with chronic urticaria and monthly income, the lower the income, the more will the quality of life be affected. Furthermore, greater CU control was observed to reduce the negative effects on quality of life caused by itching.
Antecedentes: Los niveles disminuidos de vitamina D influyen en el control y la gravedad del asma.Objetivo: Evaluar la relación entre niveles séricos de vitamina D y control del asma, así como estado nutricional, calidad de vida y comorbilidades del paciente.Métodos: Estudio transversal, observacional y descriptivo de 43 pacientes asmáticos mayores de 18 años. Se realizó análisis de varianza multivariados de regresión logística múltiple y lineal múltiples; se consideró estadísticamente significativa una p ≤ 0.05.Resultados: Se determinaron niveles insuficientes de vitamina D en 83.7 % de los pacientes; 93 % presentó al menos una exacerbación asmática en el último año. No se evidenció relación entre los niveles séricos de vitamina D y control del asma medido por el Asthma Control Test (ACT) y el volumen espiratorio forzado el primer segundo (FEV1). Se obtuvo asociación significativa entre el índice de masa corporal y niveles de vitamina D (p = 0.013). Con un cuestionario de calidad de vida en adultos asmáticos se registró que 76.7 % tenía mala calidad de vida.Conclusiones: No se observó relación entre los niveles séricos de vitamina D y el control del asma en los pacientes. La mayoría de los pacientes tenía niveles séricos de vitamina D insuficientes, asma descontrolada y mala calidad de vida. El sobrepeso y la obesidad grado I se asociaron con niveles insuficientes de vitamina D.
The measurement of the fraction of exhaled breath temperature has been used as a noninvasive biomarker in the detection of airway diseases. The purpose of our study was to compare the fraction of exhaled breath temperature (EBT) in patients with controlled and uncontrolled asthma to establish its use as a biomarker. EBT reports peripheral airway temperature (T 3 max), central (T 1 max) and the relationship between both (Rel T1/T3). METHODS: We reviewed a total of 40 records of adult asthmatic patients that were consulted at the Regional Center of Allergy and Clinical Immunology at the University Hospital in Monterrey, Mexico and to whom the EBT was measured. Patients were classified as uncontrolled or controlled asthma by the Asthma Control Test and doses of inhaled corticosteroid were documented. EBT was compared among both group of patients. Data was analyzed using SPSS 23.0. RESULTS: Nineteen patients (47.5%) had controlled asthma while 21 (52.5%) were uncontrolled. The mean of T 3 max temperature in controlled asthma using low doses of corticosteroids was 29.5; in patients with uncontrolled asthma and higher doses of inhaled corticosteroids, the mean was 28.1 with p5 0.032. CONCLUSIONS: Patients with uncontrolled asthma and higher doses of inhaled corticosteroids showed significant difference in EBT measurements compared to controlled asthma, establishing the EBT as a useful biomarker.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
