Resumen
La deshidrogenasa láctica (DHL) es un biomarcador fuertemente asociado a la gravedad, el
objetivo de esta investigación fue determinar las concentraciones de DHL y su relación con la
gravedad en pacientes COVID-19. Se diseñó un estudio retrospectivo, transversal, de tipo
probabilístico, la población estuvo conformada por 508 pacientes, de los cuales la muestra
constituida por 288 atendidos en el laboratorio Analítica Avanzada H & A durante el periodo
2021. Se clasificaron según su sintomatología en grados de severidad, también se reclasifico por
gravedad y se evaluó su relación con la DHL. Se determinó un punto de corte de 326,5 U/L y un
AUC (área bajo la curva) de 1 realizando una correcta discriminación del grupo no graves y
graves, con una media y desviación estándar de 180,7±51,26 U/L, 370,0±32,31 U/L
respectivamente. Mediante la prueba de Chi-cuadrado se afirmó que los niveles de DHL están
directamente relacionados con la gravedad en pacientes COVID-19. Además, se obtuvo que el
71,53 % tuvieron un cuadro leve (158,54 ± 29,64 U/L), el 20,14 % presentaron un cuadro
moderado (262,46 ± 23,87 U/L) y el 8,33 % un cuadro severo (372 ± 32,31 U/L). Mediante los
estadísticos de Wilcoxon se confirmo que los pacientes de grado leve tienen una concentración
de DHL normal, con T student se comprobó que los de grado moderado y severo son elevados y
muy elevados correlativamente. Concluyendo que los niveles de deshidrogenasa láctica se
relacionan con la gravedad en pacientes COVID-19.
Lactic dehydrogenase (LDH) is a biomarker strongly associated with severity, the objective of this research was to determine the concentrations of LDH and its relationship with severity in COVID-19 patients. A retrospective, cross-sectional, probabilistic study was designed, the population consisted of 508 patients, of which the sample consisted of 288 treated in the Advanced Analytics H & A laboratory during the period 2021. They were classified according to their symptoms in degrees of severity, it was also reclassified by severity and its relationship with DHL was evaluated. A cut-off point of 326.5 U/L and an AUC (area under the curve) of 1 were determined, correctly discriminating between the non-severe and severe groups, with a mean and standard deviation of 180.7±51.26 U. /L, 370.0±32.31 U/L respectively. Using the Chi-square test, it was confirmed that DHL levels are directly related to severity in COVID-19 patients. In addition, it was found that 71.53% had a mild condition (158.54 ± 29.64 U/L), 20.14% had a moderate condition (262.46 ± 23.87 U/L) and the 8.33% a severe picture (372 ± 32.31 U/L). Using Wilcoxon statistics, it was confirmed that patients with a mild degree have a normal DHL concentration, with T student it was verified that those with a moderate and severe degree are high and very high correlatively. Concluding that lactic dehydrogenase levels are related to severity in COVID-19 patients.
