Introduction Inflammatory markers such as white cell count (WCC) and C-reactive protein (CRP) and, more recently, bilirubin have been used as adjuncts in the diagnosis of appendicitis. The aim of this study was to determine the diagnostic accuracy of the above markers in acute and perforated appendicitis as well as their value in excluding the condition. Methods A retrospective analysis of 1,169 appendicectomies was performed. Patients were grouped according to histological examination of appendicectomy specimens (normal appendix = NA, acute appendicitis = AA, perforated appendicitis = PA) and preoperative laboratory test results were correlated. Receiver operating characteristic (ROC) curve area analysis (area under the curve [AUC]) was performed to examine diagnostic accuracy. Results ROC analysis of all laboratory variables showed that no independent variable was diagnostic for AA. Good diagnostic accuracy was seen for AA when all variables were combined (WCC/CRP/bilirubin combined AUC: 0.8173). In PA, the median CRP level was significantly higher than that of AA (158mg/l vs 30mg, p<0.0001). CRP also showed the highest sensitivity (100%) and negative predictive value (100%) for PA. CRP had the highest diagnostic accuracy in PA (AUC: 0.9322) and this was increased when it was combined with WCC (AUC: 0.9388). Bilirubin added no diagnostic value in PA. Normal levels of WCC, CRP and bilirubin could not rule out appendicitis. Conclusions CRP provides the highest diagnostic accuracy for PA. Bilirubin did not provide any discriminatory value for AA and its complications. Normal inflammatory markers cannot exclude appendicitis, which remains a clinical diagnosis.

The aim of this study is prospectively to evaluate the serum C-reactive protein (CRP) and interleukin-6 (IL-6) levels in detection of acute appendicitis in patients with right iliac fossa pain. Data were collected in prospective manner on 102 consecutive patients with right iliac fossa pain. Laparotomy was performed for suspected acute appendicitis for 55 of the 102 patients, of whom 49 patients had appendicitis, 6 patients non-appendicitis (NA), and the other 47 patients had nonspecific abdominal pain (NSAP) and they did not undergo operation. Among those with appendicitis 31 had acute appendix (AA), 8 had gangrenous appendix (GA), and 10 had perforated appendix (PA). The WBC and CRP the mean (SEM) values were significantly different in AA, GA, and PA groups compared with NSAP and NA groups (P < 0.05). Although the mean IL-6 levels were significantly different only in PA group than the others groups (P < 0.05). The sensitivity and specificity of serum CRP measurements were calculated as 96% and 87%, respectively whereas these were 33% and 83% for IL-6 levels for the diagnosis of the acute appendicitis. As a result, measurement of the CRP levels and WBC have an additional diagnostic value on the diagnosis of the acute appendicitis but determination of IL-6 levels which added to the test combination of WBC and CRP, the sensitivity for the diagnosis of the acute appendicitis was not changed whereas the specificity was decreased to 66%.

Objective: The objective of this research was to evaluate the diagnostic value of mean platelet volume/platelet count (MPV/PC) ratio in pediatric acute appendicitis. Methods: This retrospective study included a total of 310 patients, 176 in the uncomplicated appendicitis group, 80 in the complicated appendicitis group, and 54 in the nonspecific abdominal pain (NSAP) group. C-reactive protein (CRP) level, white blood cell (WBC) count, absolute neutrophil count (ANC), MPV, PC, and MPV/PC ratio were compared between the groups. Results: WBC and ANC levels differed significantly between the groups (P<0.001 in all pairwise comparisons). CRP levels in the complicated appendicitis group were higher than in the NSAP and uncomplicated appendicitis groups (P<0.001 for both comparisons). There was a negative correlation between MPV and PC (r= -0.434, P<0.001). Both PC and MPV/PC ratio were able to distinguish cases of complicated appendicitis from NSAP (P=0.047 and P=0.045, respectively) and from cases of uncomplicated appendicitis (P=0.010 and P=0.045, respectively). Areas under the ROC curve for CRP, WBC, ANC, MPV, PC, and MPV/PC ratio were 0.640, 0.690, 0.727, 0.553, 0.541, and 0.546, respectively. Conclusion: According to the results of our study, MPV/PC ratio can be used in addition to the conventional markers to discriminate cases of complicated appendicitis.
