Por otra parte, las tasas de α<span class="elsevierStyleInf">1</span> AT y α<span class="elsevierStyleInf">2</span> MG en esputo y su relación (esputo/suero) aumentaron significativamente en el transcurso de las infecciones pulmonares, evidenciando un importante aumento de la difusión pasiva proteica desde el plasma a la secreción bronquial. Cuando la relación esputo/suero de ambas macromoléculas fue corregida para la albúmina, no existieron diferencias significativas al comparar las distribuciones de ambaspoblaciones analizadas, sugiriendo un mecanismo de génesis común en los grupos con y sin infección pulmonar.

Sin embargo, a pesar de la contribución de α<span class="elsevierStyleInf">2</span> MG a la corrección del disbalance entre proteasas neutras e inhibidores, los sujetos portadores de EPOC con infección pulmonar intercurrente mantienen un estado de desequilibrio enzimático con elevado riesgo para la integridad del tejido conectivo pulmonar.</p></span>" ] "en" => array:1 [ "resumen" => "<span id="abst0010" class="elsevierStyleSection elsevierViewall"><p id="spar0020" class="elsevierStyleSimplePara elsevierViewall">Both proteins were determined in this study in the serum and in a colloidal solution of sputum in two groups of patients with chronic obstructive lung disease (COLD) with infection and without lower respiratory infection.</p><p id="spar0025" class="elsevierStyleSimplePara elsevierViewall">The serum levels of α<span class="elsevierStyleInf">1</span> AT augmented significantly during pulmonary infection probably due to protein metabolism, while α<span class="elsevierStyleInf">2</span> MG concentration decreased significantly during the same period suggesting either an increase in the protein catabolism, a reduction of the synthetic capacity, or the formation of stable complexes of α<span class="elsevierStyleInf">2</span> MG-bacterial endopeptidases.
