Efficacy of inhalation therapy with montelukast sodium, budesonide and formoterol in combination in the treatment of bronchial asthma in adult patients and its effects on cytokines / 中国基层医药

Objective:To investigate the efficacy of combination treatment with montelukast sodium, budesonide and formoterol in the treatment of bronchial asthma in adults and its effects on cytokines.Methods:A total of 100 adult patients with bronchial asthma who received treatment in The First People's Hospital of Yongkang from January 2019 to December 2020 were included in this study. They were randomly assigned to receive either budesonide inhalation alone (control group, n = 50) or combination inhalation of montelukast sodium, budesonide and formoterol (observation group, n = 50) for 12 weeks. Efficacy was compared between the two groups. Lung function [forced expiratory volume in one second (FEV 1), peak expiratory flow (PEF) and FEV 1/forced vital capacity (FVC) ratio], cytokines [interleukin (IL)-2, IL-4, IL-6], Asthma Quality of Life Questionnaire (AQLQ) score, and Asthma Control Test (ACT) score measured before and 12 weeks after treatment were compared between the two groups. Results:Total response rate in the observation group was significantly higher than that in the control group [92.00% (46/50) vs. 72.00% (36/50), χ2 = 6.77, P < 0.05). After 12 weeks of treatment, FEV 1, PEF and FEV1/FVC in the observation group were (2.17 ± 0.23) L, (246.56 ± 17.86) L/s, and (83.86 ± 3.98)%, respectively, which were significantly higher than (1.86 ± 0.17) L, (203.12 ± 20.10) L/s, (74.82 ± 5.67)% in the control group ( t = 7.66, 11.42, 9.22, P < 0.05). Serum IL-2 level in the observation group was significantly higher than that in the control group [(10.85 ± 0.86) ng/L vs. (8.94 ± 1.03) ng/L, t = 10.06, t < 0.05]. Serum IL-4 and IL-6 in the observation group were (24.98 ± 3.08) ng/L and (98.46 ± 9.76) μg/L, respectively, which were significantly lower than (36.75 ± 4.34) ng/L and (125.84 ± 13.19) μg/L in the control group ( t =15.63, 11.79, both P < 0.05). AQLQ score and ACT score in the observation group were (121.03 ± 8.69) points and (22.08 ± 1.35) points, respectively, which were significantly higher than (110.93 ± 7.86) points and (19.74 ± 1.76) points in the control group ( t = 6.095, 7.460, both P < 0.05). Conclusion:Inhalation therapy with montelukast sodium, budesonide and formoterol produces obvious therapeutic effects on bronchial asthma in adult patients and the combined therapy can reduce inflammatory reactions.

Beta-2 agonistas para el tratamiento de bronquiolitis / Beta-2 agonists for the treatment of bronchiolitis

INTRODUCCIÓN La bronquiolitis es la inflamación aguda de las vías aéreas de pequeño calibre, teniendo como causa principal las infecciones virales. Es altamente frecuente en menores de dos años, sobretodo en menores de 12 meses. Existe gran controversia sobre el manejo de esta patología, siendo especialmente cuestionable el uso de beta-2 agonistas de corta acción tanto en el ámbito ambulatorio como hospitalario. MÉTODOS Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud a nivel mundial, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis, y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES Identificamos siete revisiones sistemáticas que en conjunto incluyen 47 estudios primarios, de los cuales 44 corresponden a ensayos aleatorizados. Concluimos que el uso de beta-2 agonistas podría no tener ningún beneficio en el manejo de la bronquiolitis, en términos de necesidad de hospitalización y/o duración de la misma. Por otra parte, podría aumentar efectos adversos como arritmias, sin embargo, la certeza de esta evidencia es baja

Avaliação da eficácia e segurança da associação de budesonida e formoterol em dose fixa e cápsula única no tratamento de asma não controlada: ensaio clínico randomizado, duplo-cego, multicêntrico e controlado / Evaluation of the efficacy and safety of a fixed-dose, single-capsule budesonide-formoterol combination in uncontrolled asthma: a randomized, double-blind, multicenter, controlled clinical trial

OBJETIVO: Avaliar a eficácia e a segurança da associação de budesonida e formoterol em dose fixa e cápsula única, em comparação ao uso de budesonida isolada em pacientes com asma não controlada. MÉTODOS: Ensaio clínico randomizado, duplo-cego, multicêntrico, de fase III, com grupos paralelos, comparando a eficácia de curto prazo e a segurança da formulação em pó de budesonida (400 µg) e formoterol (12 µg) com a formulação em pó de budesonida (400 µg) em 181 participantes com asma não totalmente controlada. A idade dos participantes variou de 18-77 anos. Após um período de run-in de 4 semanas, durante o qual todos os participantes receberam budesonida duas vezes por dia, houve a randomização para um dos tratamentos do estudo. O tratamento foi administrado duas vezes ao dia por 12 semanas. Os principais desfechos foram VEF1, CVF e PFE matinal. Os dados foram analisados por intenção de tratar. RESULTADOS: O grupo tratado com a associação, quando comparado ao grupo budesonida isolado, teve uma melhora significativa no VEF1 (0,12 L vs. 0,02 L; p = 0.0129) e no PFE matinal (30,2 L/min vs. 6,3 L/min; p = 0,0004). Esses efeitos foram acompanhados por boa tolerabilidade e segurança, como demonstrado pela baixa frequência de eventos adversos menores. CONCLUSÕES: A associação em cápsula única de budesonida e formoterol mostrou ser eficaz e segura. Os resultados demonstram que essa formulação é uma opção terapêutica válida para a obtenção e manutenção do controle da asma.

OBJECTIVE: To evaluate the efficacy and safety of a fixed-dose, single-capsule budesonide-formoterol combination, in comparison with budesonide alone, in patients with uncontrolled asthma. METHODS: This was a randomized, double-blind, multicenter, phase III, parallel clinical trial, comparing the short-term efficacy and safety of the combination of budesonide (400 µg) and formoterol (12 µg), with those of budesonide alone (400 µg), both delivered via a dry powder inhaler, in 181 patients with uncontrolled asthma. The age of the patients ranged from 18 to 77 years. After a run-in period of 4 weeks, during which all of the patients received budesonide twice a day, they were randomized into one of the treatment groups. for 12 weeks. The treatment consisted of the administration of the medications twice a day for 12 weeks. The primary outcome measures were FEV1, FVC, and morning PEF. We performed an intention-to-treat analysis of the data. RESULTS: In comparison with the budesonide-only group patients, those treated with the budesonide-formoterol combination showed a significant improvement in FEV1 (0.12 L vs. 0.02 L; p = 0.0129) and morning PEF (30.2 L/min vs. 6.3 L/min; p = 0.0004). These effects were accompanied by good tolerability and safety, as demonstrated by the low frequency of adverse events, only minor adverse events having occurred. CONCLUSIONS: The single-capsule combination of budesonide and formoterol appears to be efficacious and safe. Our results indicate that this formulation is a valid therapeutic option for obtaining and maintaining asthma control. (ClinicalTrials.gov Identifier: NCT01676987 [http://www.clinicaltrials.gov/]).
