Hyperbilirubinemia in appendicitis -is a predictive factor of perforation?Background: An elevated total bilirubin level can be a marker for perforated appendicitis. Aim: To assess and compare the predictive value of total bilirubin, C-reactive protein (CRP), white-blood cell count, the lapse of symptoms evolution, and systemic inflammatory response syndrome (SIRS) for the diagnosis of perforated appendicitis. Material and Methods: Prospective study of 134 consecutive patients aged 33 ± 16 years (63 males) operated for acute appendicitis of whom 49 had a perforated appendix. A preoperative blood sample was obtained to measure total bilirubin, C reactive protein and complete blood count. A systemic inflammatory response score was calculated. Results: The lapse of symptoms before operation was higher in patients with perforated appendicitis compared with their counterparts without perforation (105.2 ± 79.3 and 38.6 ± 17.5 hours respectively). C reactive protein values were 176 ± 82.6 and 80 ± 76 mg/l respectively, (p = 0.01). Serum bilirubin values were 0.7 ± 0.3 and 1.0 ± 0.5 mg/dl, respectively (p = 0.05). Sixty five percent of patients with perforated appendicitis had a SIRS score between 3 and 4 points. A C reactive protein over 76.7 mg/l, a lapse of symptoms over 34.5 hours and a SIRS score of three or more had the best performance for the prediction of perforated appendicitis. Conclusions: The diagnosis of perforated appendicitis may be suspected based on CRP, SIRS, and the lapse of symptoms before operation. We do not recommend the use of total bilirubin to predict perforation in appendicitis. ResumenIntroducción: Se ha propuesto a la hiperbilirrubinemia como un marcador específico de apendicitis perforada. El objetivo del presente estudio es el de comparar el rendimiento para la predicción de perforación de la bilirrubina total (BT) y la proteína C reactiva (PCR), leucocitosis, el tiempo de evolución del cuadro clínico y el síndrome de respuesta inflamatoria sistémica (SIRS). Métodos: Se diseñó un estudio prospectivo y observacional, en el que se aplican curvas Receiver Operating Characteristics para comparar Rev.

Progression of the systemic inflammatory response in patients with appendicitisIntroduction: The systemic inflammatory response has been described in patients with appendicitis. However, its progression from the onset of symptoms to diagnosis has not been characterized. The purpose of this study was to describe and characterize the systemic inflammatory response to appendicitis. Patients and Methods: A descriptive study was conducted. One-hundred eighty-three patients were studied divided into four groups from onset of symptoms to diagnosis. Primary outcome measure was to determine the systemic inflammatory response to appendicitis according to the established groups of time intervals. Secondary outcome measure was the analysis of C-reactive protein for the same purpose. Results: The systemic inflammatory response variables according to diagnostic intervals showed non-significant differences on white blood cells count. Temperature and heart rate rises constantly after 48 h reaching their peak after 72 h (p = 0.001); the respiratory rate rises after 73 h (p < 0.0001). After 73 h most patients had 3 or 4 systemic inflammatory response criteria (p < 0.0001). C-reactive protein levels rise progressively showing higher levels after 48 hours (p = 0.005). Conclusions: The inflammatory response to appendicitis is progressive, being more marked along the timeline from onset of symptoms to diagnosis.
