RESUMEN

Objetivo:

observar el comportamiento de los niveles séricos de procalcitonina durante el curso clínico de la sepsis en la población local.

Metodología:

estudio de cohorte prospectivo. Se ingresaron al estudio pacientes admitidos a la unidad de cuidados intensivos del hospital clínica Kennedy, sede Policentro, con diagnóstico de sepsis y sin tratamiento antibiótico por mas de 48h previas al ingreso. Se obtuvo valores séricos de procalcitonina (PCT), proteína C reactiva (PCR) y se calcularon los scores APACHE II y MODS al momento del ingreso y diariamente hasta la resolución del cuadro séptico o muerte del paciente.

Resultados:

ocho pacientesfueron incluidos en el estudio. Se observó una mayor disminución porcentual de PCT en sobrevivientes que no-sobrevivientesentre D1-D2 y D2-D3 (-54.48 por ciento y -60.15 por ciento vs. 1553.97 por ciento y 0 por ciento); lo cual no ocurrió con la PCR. Se observó una débil correlación de la PCT con la PCR en el tiempo (r=0,46). La correlación de la PCT con APACHE II y MODS fue mayor que con la PCR (r=0.88 y 0.81 vs 0.60 y 0.53).

Conclusiones:

una disminución >30 por ciento entre D1-D2 y >50 por ciento entre D2-D3 de los niveles séricos de PCT se asocian a un pronóstico favorable. La PCT puede ser mas útil que la PCR en la monitorización diaria de la terapia en pacientes sépticos. La PCT tiene una mayor correlación que la PCR con el curso clínico del paciente séptico de acuerdo a los scores APACHE II y MODS
ABSTRACT

Aim:

to observe the behavior of the procalcitonin serum levels during the clinical course of the sepsis in the local population.

Methodology:

prospective cohort study. Patients admitted to the intensive care unit of the Kennedy general hospital diagnosed with sepsis and without antibiotic treatment for more than 48 hours prior to admission were considered for the research. Serum levelsof procalcitonin (PCT) and C reactive protein (CRP) were obtained, and APACHE II and MODS scores were calculated at admission and daily until the resolution of the septic picture or death of the patient.

Results:

eight patients were included in the research. A higher percentage decrease in PCT was observed in survivors than non-survivors between D1-D2 and D2-D3 (-54.48 percent and -60.15 percent vs. 1553.97 percent and 0 percent); which did not occur with CRP. A weak correlation of PCT and CRP over time (r=0.46) was observed. The correlation of PCT with APACHE II and MODS was higher than with the CRP (r=0.88 and 0.81 vs 0.60 and 0.53).

Conclusions:

adecrease > 30 percent between D1-D2 and > 50 percent between D2-D3 serum levels of PCT are associated with a favorable prognosis. PCT can be of major use than CRP in terms of daily monitoring of the therapy in septic patients. PCT has a higher correlation with the clinical course of the septic patient than CRP according to the APACHE II and MODS scores.
