“…Moreover, it is necessary to carry out studies which could explain the existence of vitamin K deficiency in CF patients despite its supplementation. [16][17][18][19][20][21] Therefore, finding endogenous and exogenous determinants of vitamin K deficiency could help to determine the appropriate vitamin K dosage in order to maintain its normal body resources in CF patients. This study is the first to recruit a large group of CF patients without vitamin K supplementation in order to analyze potential determinants of its deficiency.…”

“…[16][17][18][19][20][21] Therefore, identifying potential risk factors for vitamin K deficiency in CF patients seems to be very important. Nevertheless, reliable predictive factors have not been determined for CF subjects receiving vitamin K. 21 Hence, the aim of the present study was to assess the prevalence of vitamin K deficiency and associated factors in nonsupplemented cystic fibrosis patients.…”

“…Considerando la función biológica de la vitamina K, el aporte suplementario parece ser muy importante en los pacientes con FQ que tienen riesgo de deficiencia de vitamina K. Además, es necesario realizar estudios para explicar la existencia de deficiencia de vitamina K en los pacientes con FQ a pesar del aporte suplementario. [16][17][18][19][20][21] Por lo tanto, los determinantes endógenos y exógenos de la deficiencia de vitamina K podrían servir para precisar la posología de vitamina K adecuada para mantener la fuente corporal normal en los pacientes con FQ. Este es el primer estudio que incluyó a un gran grupo de pacientes con FQ que no recibían aporte suplementario de vitamina K para poder analizar los determinantes potenciales de deficiencia de esta vitamina.…”

“…[16][17][18][19][20][21] Por lo tanto, adquiere mucho valor la identificación de los factores de riesgo de la deficiencia de vitamina K en los pacientes con FQ. Sin embargo, no se han determinado factores predictivos fiables para los sujetos con FQ que reciben vitamina K. 21 Por lo tanto, el objetivo de este estudio fue evaluar la prevalencia de la deficiencia de vitamina K y los factores asociados en los pacientes con FQ que no recibían aporte suplementario.…”

“…В нескольких исследованиях была продемостриро вана высокая распространенность недостаточности витамина К [44][45][46] у детей и взрослых, больных МВ, однако его не часто применяют в специализи рованных центрах. В некоторых публикациях описа но положительное влияние витамина К на биохими ческие показатели костного обмена у больных МВ, однако оптимальный режим его назначения, осо бенно при панкреатической недостаточности, оста ется неясным [46][47][48].…”
