ABSTRACT

Summary A 66-year-old male patient was referred to our clinic with severe pneumonia. Bronchoscopy was performed due to clinical worsening despite antibiotics and diuretic therapy, respiratory failure and radiographic progression. Because bacterial cultures of the bronchoalveolar lavage fluid were negative and after using amiodarone for almost one month, we eliminated amiodarone from his medication regimen due to suspicion of amiodarone toxicity. Accordingly, we also initiated systemic steroid therapy. Chest X-ray done after 72 hours showed a significant resolution of lung consolidations and the patient exhibited significant clinical improvement, with decline of his oxygen requirements.

ABSTRACT

Summary Objectives: vitamin D is important for muscle function and it affects different aspects of muscle metabolism. This study aim to determine whether serum 25(OH) D levels are related to lung functions, physical performance and balance in patients with chronic obstructive pulmonary disease (COPD). Methods: in 90 patients with COPD and 57 healthy controls lung function tests, physical performance tests (time up and go, gait velocity test, sit-to-stand test, isometric strength, isokinetic strength), static (functional reach test) and dynamic (time up and go) balance tests and the association of 25(OH)D levels with lung functions, physical performance and balance were evaluated. Results: the COPD patients had significantly more deficit in physical function and balance parameters, and in dynamic balance test (p<0.005). Isokinetic knee muscle strength (flexor and extensor) in COPD patients was significantly lower than in the controls (p<0.05); FEV1 (p=0.008), FVC (p=0.02), FEV1/FVC (p=0.04), TLC (p=0.01) were lower in COPD patients with vitamin D deficiency [25(OH) D less than 15ng/mL] than in COPD patients without vitamin D deficiency. Hand grip test (p=0.000) and isokinetic knee muscle strength (flexor and extensor) (p<0.05) were also lower in COPD patients with vitamin D deficiency. Vitamin D deficiency was more pronounced in patients with stage III COPD (p<0.05). Conclusion: patients with COPD had worst physical functioning, poor balance and less muscle strength. Severe disturbed lung and peripheral muscle functions are more pronounced in COPD patients with vitamin D deficiency. .


Resumo Objetivos: a vitamina D é importante para a função muscular e afeta diferentes aspectos do metabolismo muscular. O objetivo é determinar se os níveis séricos de 25 (OH) D estão relacionados com as funções pulmonares, desempenho físico e equilíbrio em pacientes com doença pulmonar obstrutiva crônica (DPOC). Métodos: em 90 pacientes com DPOC e 57 controles saudáveis, testes de espirometria, testes de desempenho (tempo de levantar e ir, teste de velocidade da marcha, teste sitto-stand, força isométrica, força isocinética) e testes de estática (teste de alcance funcional) e dinâmica (tempo de levantar e ir) de equilíbrio foram realizados; e foram avaliados a associação de níveis de 25 (OH) D com as funções pulmonares, desempenho físico e equilíbrio. Resultados: os pacientes com DPOC apresentaram significativamente mais déficit nos parâmetros de função e equilíbrio físico, e no teste de equilíbrio dinâmico (p<0,005). Força muscular isocinética do joelho (flexores e extensores) em pacientes com DPOC foi significativamente menor do que nos controles (p<0,05); VEF1 (p=0,008), CVF (p=0,02), VEF1/CVF (p=0,04), CPT (p=0,01) foram mais baixos em pacientes com DPOC e com deficiência de vitamina D [25 (OH) D menor do que 15 ng/ml] do que em pacientes com DPOC sem deficiência de vitamina D. Os resultados do teste da força de preensão manual (p=0,000) e força muscular isocinética do joelho (flexor e extensor) (p<0,05) também foram menores nos pacientes com DPOC e com deficiência de vitamina D. A deficiência de vitamina D foi mais pronunciada em pacientes em estágio III da DPOC (p<0,05). Conclusão: pacientes com DPOC tiveram pior desempenho físico, falta de equilíbrio e menor força muscular. Perturbações graves das funções pulmonares e musculares periféricas são mais pronunciadas em pacientes com DPOC e com deficiência de vitamina D. .
