Objective. Main objective was whether the combination of C-Reactive Protein (CRP) and Alvarado Score (AS) increase the diagnosis accuracy of AS among 2-to-20-year-old patients with suspected acute appendicitis presenting to Emergency Departments. Materials and methods. This is a secondary analysis of prospective cohort study consecutively including all patients from 2 to 20 years of age attended for suspected acute appendicitis in 4 Spanish Emergency Departments during 6-month period. We collected demographic, clinical, analytic and radiographic, and surgical data. AS categories were retrospectively calculated as low (0-4 points), intermediate (5-6 points) or high (7-10 points). The cut-off levels were >0.5 mg/dl for CRP. The outcome was diagnosis of acute appendicitis within 14 days of the index visit. Results. A total of 331 patients with suspected of acute appendicitis (mean age 11.8 (SD 3.8) years; 52.9% males) were recruited. According to AS, 108 (32.6%) were at low risk, 76 at (23.0%) intermediate risk and 147 (44.4%) at high risk of acute appendicitis. One hundred and sixteen (35.0%) cases had confirmed histopathological diagnosis of acute appendicitis. The AUCs of ROC were 0.76 (0.70-0.81) for AS and 0.79 (95% CI 0.75-0.84) for CRP-AS being the difference statistically significant (p=0.003). The CRP for diagnosis acute appendicitis in low risk AS group had negative predictive value of 95.8% (95%CI 87.3-98.9) and likelihood ratio negative of 0.4 (95%CI 0.2-1.0). Conclusions. CRP-AS has shown to increase the diagnostic accuracy of AS for acute appendicitis. This approach may be useful to rule out the diagnosis of acute appendicitis in paediatric patients attended for abdominal pain suggestive of acute appendicitis.

Abstract Background The diagnosis of acute appendicitis in children is quite challenging as the rate of negative appendectomy varies between 15 and 57%. Increased utilization of imaging diagnostic facilities in advanced countries seems to have reduced the incidence of operating on normal appendix to a single digit. In low- and middle-income countries, the incidence remains unacceptably high (double digits). Inflammatory markers and scoring systems may be a suitable adjunct to increase diagnostic yield in most third world countries. Thus, the aim of this study was to evaluate the diagnostic value of Alvarado score, white blood cell count, and serum C-reactive protein in children with acute appendicitis. Results The ages of patients ranged between 4 and 15 years with a mean of 11.2 ± 2.8 years. The male to female ratio was 1.4 to 1.0. Nineteen percent of patients had negative appendiceal findings on histological examination. The sensitivity and specificity of Alvarado score, C-reactive protein estimation, total white blood cell count in diagnosing acute appendicitis were 86.4% and 63.2%, 98.8% and 36.8%, and 51.9% and 89.5% respectively. Alvarado score has the highest area under ROC curve analysis 0.824, 95% CI of 0.724 to 0.924 compared with CRP, 0.769. 95% CI of = 0.647 to 0.891 and WBC count, 0.765, 95% CI of 0.643 to 0.887. Both CRP and WBC count showed higher discriminatory values between complicated and uncomplicated appendicitis, p < 0.001. Conclusion Alvarado score outperformed other tests in setting the diagnosis of acute appendicitis. However, none of the tests can be relied on wholly for operative decision. Clinical judgement remains the bedrock for diagnosis and operative management.

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.

Abstract Background The typical history of acute appendicitis is observed in less than 60% of cases. Therefore, searching for a surrogate marker is mandatory. Our goal was to determine whether the soluble triggering receptor expressed on myeloid cells (sTREM-1) is an efficient biomarker for acute appendicitis. Methods sTREM-1 serum levels were measured in addition to carrying out routine diagnostic tests (urine dipstick, complete blood count and C- reactive protein) in children admitted to the Emergency Department with suspected appendicitis. Statistical analysis was performed in order to examine whether sTREM-1 was a significant predictor of appendicitis. Results Fifty three of 134 children enrolled in the study were diagnosed with appendicitis. There was no significant difference in serum sTREM-1 levels (p=0.111) between children with or without appendicitis. Leukocytes, neutrophils and CRP were significantly elevated in the appendicitis group (p<0.001). The appendix diameter was significantly larger and the Alvarado score significantly higher in the appendicitis group (p<0.001). Conclusion serum sTREM-1 is not a good marker for acute appendicitis. Customary tests in addition to a proper patient history and physical examination are still the most effective methods to diagnose acute appendicitis.

Background: To evaluate and compare diagnostic accuracy of modified Alvarado score and ultrasonography in co-relation to histopathology report for diagnosis of acute appendicitis.Methods: A prospective study of the patients who underwent appendectomy for suspected acute appendicitis at IIMS and R Medical College and Noor Hospital Warudi, Badnapur, Dist. Jalna (Maharashtra). The clinical (radiological) and ultrasonography data of 760 patients with suspected appendicitis was collected between March 2014 to Feb. 2017. These patients were evaluated by modified Alvarado score and ultrasonographically, which was corrected with histopathological finding.Results: Out of 760 patients 69.34% had acute appendicitis 63.81% had modified Alvarado score≥7 and 58.28% patients were ultrasonographically positive. In present study modified Alvarado score has sensitivity of 89.37% specificity 93.99% positive predictive value 97.11%, negative predictive value 79.64%, diagnostic accuracy of 81.32%.Conclusions: Modified Alvarado score can be used effectively in clinical decision making. When compare with ultrasonography neither one is advantageous. However, additional information provided by ultrasonography improves diagnostic accuracy.
