Abstract
OBJECTIVE Possible childhood appendicitis is a common emergency presentation. The exact value of blood tests is debated. This study sought to determine the diagnostic accuracy of four blood tests (white cell count (WCC), neutrophil(count or percentage), C reactive protein (CRP) and/or procalcitonin) for childhood appendicitis. DESIGN A systematic review and diagnostic meta-analysis. Data sources included MEDLINE, EMBASE, Central, Web of Science searched from inception-March 2022 with reference searching and authors contacted for missing/unclear data. Eligibility criteria was studies reporting the diagnostic accuracy of the four blood tests compared to the reference standard (histology or follow-up). Risk of bias was assessed (QUADAS-2), pooled sensitivity and specificity were generated for each test and commonly presented cut-offs. To provide insight into clinical impact, we present strategies using a hypothetical cohort. RESULTS 67 studies were included (34 839 children, 13 342 with appendicitis), all in the hospital setting. The most sensitive tests were WCC (≥10 000 cells/µL, 53 studies sensitivity 0.85 (95% CI 0.80 to 0.89)) and absolute neutrophil count (ANC) (≥7500 cells/µL, five studies sensitivity 0.90 (95% CI 0.85 to 0.94)). Combination of WCC or CRP increased sensitivity further(≥10 000 cells/µL or ≥10 mg/L, individual patient data (IPD) of 6 studies, 0.97 (95% CI 0.93 to 0.99)).Applying results to a hypothetical cohort(1000 children with appendicitis symptoms, of whom 400 have appendicitis) 60 and 40 children would be wrongly discharged based solely on WCC and ANC, respectively, 12 with combination of WCC or CRP.The most specific tests were CRP alone (≥50 mg/L, 38 studies, specificity 0.87 (95% CI 0.80 to 0.91)) or combined with WCC (≥10 000 cells/µL and ≥50 mg/L, IPD of six studies, 0.93 (95% CI 0.91 to 0.95)). CONCLUSIONS The best performing single blood tests for ruling-out paediatric appendicitis are WCC or ANC; with accuracy improved combining WCC and CRP. These tests could be used at the point of care in combination with clinical prediction rules. We provide insight into the best cut-offs for clinical application. PROSPERO REGISTRATION NUMBER CRD42017080036.

Abstract
The diagnostic role of serum cytokines depends on the etiology and pathogenesis of acute appendicitis but the clinical significance of these cytokines in the differential diagnosis of complicated acute appendicitis remains unclear. To investigate the prediction of progression and diagnostic values of interleukin-6, interleukin-1 beta, and tumor necrosis factor-alpha in complicated acute appendicitis. This study was conducted in 100 patients with a definitive diagnosis of acute appendicitis and 20 individuals assigned for the control group. Venous blood was collected to assess biochemical tests, as well as interleukin-6, interleukin-1β, and tumor necrosis factor-α levels. Serum levels of all parameters were dramatically higher in the complicated group compared with uncomplicated. Duration of hospitalization, rates of postoperative infection, intraabdominal abscess, and re-hospitalization were higher in complicated group. Cut-off points of WBC, CRP, NLR, interleukin-6, interleukin-1β and tumor necrosis factor-α were 13.5x103/µL, 1.92 mg/dL, 6.09, 23.4 pg/mL, 5.6 pg/mL and 24 pg/mL (p=0.0014, p<0.001, p=0.009, respectively and p<0.001 for the rest). AUC of interleukin-6 was larger than AUCs of all other parameters, suggesting the highest predicting power of interleukin-6 among other parameters. Serum interleukin-6, interleukin-1β, and tumor necrosis factor-α levels are valuable diagnostic parameters to predict a complicated acute appendicitis.

Abstract
Acute appendicitis is the most common surgical emergency in children. Despite the high incidence rate of appendicitis, it is sometimes misdiagnosed or missed. Complex appendicitis (CA) in children is characterized by a critical condition, several complications, and high mortality. Precision distinguishing between simple appendicitis and CA correctly is key to choosing appropriate treatment. A safe, cheap, rapid, extensive and accurate diagnostic marker of appendicitis will be of great significance for emergency general surgeons to treat suspected CA. Many studies have investigated possible diagnostic markers for the diagnosis of CA in children. In this study, studies related to CA in children in recent years are summarized, and the related markers and scoring system for the diagnosis of CA in children are summarized.

sB7H3 in Children with Acute Appendicitis: Its Diagnostic Value and Association with Histological Findings. J Immunol Res 2020; 2020:2670527. [PMID: 32953890 PMCID: PMC7482032 DOI: 10.1155/2020/2670527] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2020] [Revised: 06/19/2020] [Accepted: 07/27/2020] [Indexed: 11/18/2022] Open
Abstract
Background Several efforts have been made to find out a valuable marker to assist the diagnosis and differentiation of gangrenous/perforated appendicitis. We aimed to determine the diagnostic capacity of soluble B7H3 (sB7H3) in acute appendicitis (AA) and its accuracy as a predictor of the severity of appendicitis. Methods 182 children were allocated into four groups as follows: control group (CG, 90), simple appendicitis (SA, 12), purulent appendicitis (PA, 49), and gangrenous appendicitis (GA, 31). Prior to appendectomy, blood was collected and sent for analysis of routine examination and cytokines (sB7H3 and TNF-α). We compared values of all measured parameters according to histological findings. Furthermore, we assigned AA patients into the nonperforated appendicitis group and the perforated appendicitis group. The diagnostic effects of significant markers were assessed by ROC curves. Results Only the levels of CRP, FIB, and sB7H3 had a remarkable rising trend in AA-based groups, while differences in the levels of CRP and FIB between simple appendicitis and purulent appendicitis were not statistically significant. In addition, sB7H3 was found as the only marker in children with AA, which was markedly associated with the degree of histological findings of the appendix. Furthermore, sB7H3 had a high diagnostic value in predicting AA and complex appendicitis (PA+GA) in children. However, the diagnostic performance of sB7H3 for distinguishing PA from GA was not remarkable. Additionally, only the levels of CRP and sB7H3 were statistically different between the nonperforated appendicitis group and the perforated appendicitis group. The diagnostic performance of CRP and sB7H3 could not merely predict perforation of AA in children; however, the diagnostic performance was improved after combination. Conclusions sB7H3 could be used as a valuable marker to predict the presence of AA and complex AA in children. However, the diagnostic value of sB7H3 to predict gangrenous/perforated appendicitis was not found to be remarkable. The combination of sB7H3 and CRP might improve the prediction of perforated appendicitis.

[PMID: 31886585 DOI: 10.1111/ped.14131] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 11/22/2019] [Accepted: 12/25/2019] [Indexed: 12/29/2022]
Abstract
BACKGROUND The aim of this study is to determine whether pentraxin 3 (PTX3) levels can be used in the diagnosis of appendicitis in children. METHODS Fifteen children under 18 years old, who gave blood samples for reasons other than inflammatory conditions, and 40 children who were proved to have appendicitis (non-perforated or perforated) between August 2017 and January 2018, were enrolled in the study. Patients were classified into subgroups: group 1 (healthy children without any sign of inflammation, n = 15), group 2 (non-perforated appendicitis, n = 25), and group 3 (perforated appendicitis, n = 15). RESULTS The median PTX3 value was 1.01 ng/mL (minimum value: 0.82, maximum: 1.28) in the control group. The median PTX3 values prior to surgery were 20.68 ng/mL (minimum: 1.02, maximum: 28.471) and 1.46 (minimum: 1.05, maximum: 23.421) ng/mL for non-perforated appendicitis and perforated appendicitis respectively. The PTX3 levels were significantly higher in groups 2 and 3 than in group 1 (P < 0.01). According to receiver operating characteristics analysis the cut-off value of PTX3 levels at admission for appendicitis was 1.30 ng/mL with a sensitivity of 75% and a specificity of 100% (area under the curve, 0.939; P = 0.000). CONCLUSIONS Pentraxin 3 levels were significantly higher in children with appendicitis than in healthy children. Children with high PTX3 levels complaining of right lower quadrant pain may support a diagnosis of appendicitis. Future studies should be conducted to evaluate changes in PTX3 levels by comparing children with appendicitis versus acute abdominal pain in larger populations to further determine the value of PTX3 in the diagnosis of appendicitis in children.

Abstract
This study assessed the severity of the disease through the preoperative clinical manifestations and inflammatory reaction indicators of acute appendicitis, and established a score table to predict complicated appendicitis (CA).The clinical data of 238 patients with acute appendicitis in our hospital were retrospectively analyzed, which included 18 patients with acute simple appendicitis (7.6%), 170 patients with acute purulent appendicitis (72.0%), and 48 patients with acute gangrene and perforation (20.3%). The clinical manifestations and inflammatory reaction indicators were analyzed by univariate logistic regression. Multivariate logistic regression analysis was performed to screen out the independent risk factors of CA. The β coefficients of independent risk factors entering the multivariate model were assigned by rounding, and the total score was the sum of values of all factors. Finally, verification and analysis were performed for the predictive model, and the operating characteristic curve (ROC) curve was drawn. Then, the area under the curve (AUC) was compared with the THRIVE scale, and the Hosmer-Lemeshow method was used to evaluate whether the model fitted well.The multivariate logistic regression analysis of independent risk factors was performed, and the values were rounded to the variable assignment based on the β coefficient values. The plotted ROC and AUC was calculated as 0.857 (P < .001). Using the Hosmer-Lemeshow method, the X-value was 12.430, suggesting that the prediction model fitted well.The scoring system can quickly determine whether this is a CA, allowing for an earlier and correct diagnosis and treatment. Furthermore, the scoring system was convenient, economical, and affordable. Moreover, it is easy to popularized and promote.
