Abstract
There are two types of treatment for acute appendicitis (AA): surgery and antibiotic therapy. Some patients with complex appendicitis are treated with surgery; however, for uncomplex appendicitis, most could be treated effectively with antibiotics instead. How to distinguish complex appendicitis from uncomplex appendicitis before surgery is currently unknown. The present study aimed to assess the efficacy of the laboratory parameters to diagnose complicated appendicitis. Data from 1,514 cases with acute appendicitis who were admitted to Beijing Tsinghua Changgung Hospital and Beijing Aerospace General Hospital (both Beijing, China) from January 2016 to September 2021 were retrospectively analyzed. All cases were divided into uncomplicated and complicated appendicitis. Independent variables were analyzed by uni- and multivariate logistic regression analyses. Receiver operating characteristic (ROC) curve analysis was used to identify significant parameters in the multivariate logistic regression analysis. Cut-off values, sensitivity, specificity and accuracy with area under the curve (AUC)>0.600 were considered significant parameters. Significant differences were found in age (P<0.001), body temperature (P<0.001), white blood cell (WBC) count (P<0.001), C-reactive protein (CRP; P<0.001), neutrophil count (P<0.001), neutrophil-to-lymphocyte ratio (NLR, P=0.019), platelet-to-lymphocyte ratio (PLR, P<0.001), platelet count (P<0.001), coefficient of variation (CV) and standard deviation (SD) of red blood cell distribution width (RDW); both P<0.001), mean platelet volume (MPV, P<0.001) and total (P<0.001) and direct bilirubin (P<0.001) between the two groups. CRP, neutrophil count, NLR, PLR, platelet count, RDW-CV, RDW-SD, MPV and direct bilirubin levels were found as the independent variables to diagnose complicated appendicitis. In patients with acute appendicitis, CRP >22.95 mg/l, NLR >5.7, serum direct bilirubin >6.1 mmol/l and RDW-SD>17.7 fl were significantly associated with complicated appendicitis.

Abstract
Sepsis globally accounts for an alarming annual toll of 48.9 million cases, resulting in 11 million deaths, and inflicts an economic burden of approximately USD 38 billion on the United States healthcare system. The rise of multidrug-resistant organisms (MDROs) has elevated the urgency surrounding the management of multidrug-resistant (MDR) sepsis, evolving into a critical global health concern. This review aims to provide a comprehensive overview of the current epidemiology of (MDR) sepsis and its associated healthcare challenges, particularly in critically ill hospitalized patients. Highlighted findings demonstrated the complex nature of (MDR) sepsis pathophysiology and the resulting immune responses, which significantly hinder sepsis treatment. Studies also revealed that aging, antibiotic overuse or abuse, inadequate empiric antibiotic therapy, and underlying comorbidities contribute significantly to recurrent sepsis, thereby leading to septic shock, multi-organ failure, and ultimately immune paralysis, which all contribute to high mortality rates among sepsis patients. Moreover, studies confirmed a correlation between elevated readmission rates and an increased risk of cognitive and organ dysfunction among sepsis patients, amplifying hospital-associated costs. To mitigate the impact of sepsis burden, researchers have directed their efforts towards innovative diagnostic methods like point-of-care testing (POCT) devices for rapid, accurate, and particularly bedside detection of sepsis; however, these methods are currently limited to detecting only a few resistance biomarkers, thus warranting further exploration. Numerous interventions have also been introduced to treat MDR sepsis, including combination therapy with antibiotics from two different classes and precision therapy, which involves personalized treatment strategies tailored to individual needs. Finally, addressing MDR-associated healthcare challenges at regional levels based on local pathogen resistance patterns emerges as a critical strategy for effective sepsis treatment and minimizing adverse effects.

Abstract
BACKGROUND Appendicitis is the most common abdominal surgical emergency and up to our knowledge no previous studies have been conducted in Saudi Arabia particularly at Qassim region and this study aimed to determine a total and direct bilirubin as a predictor of acute complicated appendicitis. METHODS Observational retrospective study that included patients admitted under the general surgery department with a diagnosis of acute appendicitis at King Saud Hospital, Unaizah, Saudi Arabia. Data on age, gender, BMI, diabetes mellitus, total and direct bilirubin, AST, ALT, sodium, and WBCs levels were obtained. RESULT Among the overall study population of 158 patients, the age median [IQR] was 24.5 [19-31], males were 99 (62.7%), and complicated appendicitis was 33 (20.9%). The multivariable analysis revealed that both elevated total and direct bilirubin are associated with complicated appendicitis (aOR = 3.79, 95% CI: 1.67-8.48, P = 0.001) and (aOR = 4.74, 95% CI: 2.07-10.86, P < 0.001) respectively. A receiver operating characteristic curve showed the best cutoff value of total and direct bilirubin as ≥ 15 µmol/L and ≥ 5 µmol/L respectively, with a sensitivity of 57.6%, and specificity of 73.6% for elevated total bilirubin, and a sensitivity of 54.6%, and specificity of 80% for elevated direct bilirubin. CONCLUSION Elevated total and direct bilirubin are associated with acute complicated appendicitis in this setting. However, it should be supportive factor for acute complicated appendicitis and not considered as standalone diagnostic test.

Abstract
Background Acute appendicitis is one of the events most frequently encountered by general surgeons. Despite the high incidence, serious problems are experienced in the diagnosis and clinical follow-up. In the pathogenesis of the disease, oxidative stress and impaired antioxidant defense mechanisms created in the body by this stress play an important role. As dynamic thiol-disulfide hemostasis is closely related to oxidative stress and is known to have a crucial role in the pathogenesis of oxidative stress, this study aimed to compare its value with other inflammatory markers in the diagnosis and follow-up of acute appendicitis. Methodology This study included cases admitted for surgery with a diagnosis of acute abdomen at Keçiören Research and Training Hospital General Surgery Clinic between April 2015 and July 2015 who were intraoperatively diagnosed with acute appendicitis and underwent routine appendectomy. In the preoperative period and after clinical healing before discharge, blood samples were obtained to examine white blood cell (WBC), mean platelet volume (MPV), total bilirubin, C-reactive protein (CRP), and thiol-disulfide balance, and the results were recorded. Results A total of 68 cases were operated on for acute appendicitis, and 59 were evaluated comprising 23 (39%) females and 36 (61%) males with a mean age of 35.6 years (range = 19-65 years). The mean duration of hospital stay was two days (range = 1-8 days). The results of the tests performed preoperatively and before discharge and their p-values were as follows: native thiol (-SH) 393.5 ± 9.4 µmol/L and 369.3 ± 9.5 µmol/L (p = 0.04), total thiol 434 ± 9.7 µmol/L and 396.7 ± 10.2 µmol/L (p = 0.03), disulfide (-S-S) 16.8 ± 0.7 µmol/L and 15.7 ± 0.9 µmol/L (p = 0.3), WBC 13.2 ± 0.5 × 10³/mL and 9.2 ± 0.4 × 10³/mL (p = 0.0), CRP 8.17 ± 1.24 mg/L and 7.84 ± 0.82 mg/L (p = 0.17), MPV 7.4 ± 0.37 fL and 7.97 ± 0.19 fL (p = 1.0), and total bilirubin 0.86 ± 0.08 mg/dL and 0.69 ± 0.06 mg/dL (p = 0.08). Conclusions In the clinical follow-up of acute appendicitis patients, the decrease in WBC, total thiol, and native thiol values can be helpful to clinicians as markers of clinical healing. However, CRP may not be a useful marker of clinical healing in acute appendicitis patients who are discharged early.

Hyperbilirubinemia and Hyponatremia as Predictors of Complicated Appendicitis. Med Sci (Basel) 2022; 10:medsci10030036. [PMID: 35893118 PMCID: PMC9326721 DOI: 10.3390/medsci10030036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 06/25/2022] [Accepted: 06/30/2022] [Indexed: 11/16/2022] Open
Abstract
Several studies have reported elevated serum bilirubin or reduced serum sodium levels in patients with complicated appendicitis (CA). This study examined the efficacy of hyperbilirubinemia, hyponatremia, and both combined in the preoperative diagnosis of CA. Patients who underwent surgery for acute appendicitis were included in this retrospective review. In total, 247 patients were included in the final analysis. Of these, 36 (14.2%) had early appendicitis, 177 (72.0%) had acute suppurative appendicitis, 32 (13.0%) had necrotizing/gangrenous acute appendicitis, and 2 (0.8%) had other types of appendicitis. The mean total bilirubin (TBIL) level was significantly higher in patients with CA than in those with uncomplicated appendicitis. Conversely, the mean serum sodium level was significantly lower in patients with CA than in those with uncomplicated appendicitis. The levels of TBIL (odds ratio: 1.098, 95% CI: 1.052–1.147) and serum sodium (odds ratio: 0.743, 95% CI: 0.646–0.855) were associated with CA. Hyponatremia combined with hyperbilirubinemia yielded significant discriminatory value for the diagnosis of CA. TBIL and serum sodium levels can be considered as adjuvant parameters in the diagnosis of perforated/necrotizing appendicitis. Although hyperbilirubinemia and hyponatremia together were better able to determine the risk of CA than either marker alone, other markers are required to definitively predict CA. Furthermore, large-scale studies are needed to confirm these findings.

Abstract
BACKGROUND Acute appendicitis (AA) is a common cause of abdominal pain in developed countries. In patients with suspected AA, computed tomography (CT) is considered as the gold standard with the highest sensitivity and specificity, and it is also an im-portant modality, especially in patients with complicated AA. In this study, we aimed to evaluate age and laboratory findings, as well as specific CT findings in differentiating between perforated and non-perforated appendicitis. METHODS We retrospectively analyzed 252 patients diagnosed with AA and underwent appendectomy between November 2015 and December 2019 in Somalia Mogadishu Recep Tayyip Erdogan Education and Research Hospital. Patients under 18 years of age and those with no pre-operative CT scans were excluded from the study. The demographic, laboratory, CT findings, and pathological data of all patients were evaluated. RESULTS This study included 80 patients, 32 (40%) classified as perforated appendicitis (Group-1) and 48 (60%) as non-perforated appendicitis (Group-2). The C-reactive protein value was found to be statistically higher in Group-1 than in Group-2 (177.5±118.9 and 100.2±87.3 mg / L, respectively; p=0.001). The appendix lumen diameter (p=0.002), appendix wall defect (p<0.001), peritoneal thickening and enhancement (p<0.001), ascites (p=0.031), intra-abdominal abscess (p=0.003), jejunal thickening (p=0.019), ileal thick-ening (p=0.008), and ileus (p=0.035) values were significantly higher in Group-1. In the binominal logistic regression analysis performed with statistically significant data, an appendiceal wall defect (OR: 0.069, 95% CI=0.014-0.327, p=0.001) and peritoneal thickening and enhancement (OR: 0.131, 95% CI=0.024-0.714, p=0.019) were identified as independent variables for perforated appendicitis. CONCLUSION Among CT findings, appendix wall defects and peritoneal thickening and enhancement play an important role in detecting perforation.

Abstract
BACKGROUND The aim of the study was to investigate the predictive value of hyponatremia as a new biochemical marker for the early and accurate preoperative diagnosis of complicated appendicitis in the adult population. METHODS 732 patients who were operated for acute appendicitis (AA) and diagnosed as perforation intraoperatively were evaluated retrospectively. Serum sodium, C-reactive protein (CRP), and leukocyte levels of patients with perforated and nonperforated appendicitis were compared. RESULTS Perforated appendicitis patients had statistically lower serum Na values (p<0.001). Similarly, patients without perforated appendicitis had higher serum CRP values (p<0.001). In patients diagnosed with perforated AA, the sensitivity of plasma sodium concentration was 63%, and the specificity was 66%. The threshold value of plasma sodium concentration ≤137.5 mEq/L had the best possible sensitivity and specificity. CONCLUSION Hyponatremia is a new marker of perforated appendicitis and therefore, serum sodium level measurement should be considered in patients with a clinical presentation consistent with appendicitis if complications are suspected.

Abstract
Introduction Acute appendicitis is a common emergency surgical presentation. The gold standard treatment is surgery. Like any surgical procedure, appendicectomy is associated with complications. Negative appendicectomy (NA) can occur, and its incidence is 15%-39%. This study aimed to evaluate the rate and predictors of NA in a cohort. Patients and methods A retrospective study over a year through which data of patients who underwent emergency appendicectomies were collected and analyzed. The absence of inflammatory process and/or other significant pathology in the appendix was considered negative for appendicitis. An utter definition of NA was the absence of inflammatory cells in the appendix. The NA rate (NAR) was calculated using the standard criteria (NAR-SDC) and the strict criteria (NAR-STC). The routine laboratory parameters for diagnosing acute appendicitis on admission were collected. Increased inflammatory markers in the form of leucocytosis of total WBC > 11,000 per mm, elevated CPR > 5 mg/L, and isolated elevated total serum bilirubin > 20 µmol/L, were suggestive of acute appendicitis. Results Three hundred and seventy-two patients were included, 179 males and 193 females with a median age were 27 (5-94) years. The median duration of symptoms and waiting time to surgery were two days and one day, respectively. The mean admission WBC, C-reactive protein (CRP) and serum bilirubin levels were 12,600 (3,000-38,000)/mm3, 66.9 (1-323) mg/L and 12.7 (4-38) µmol/L respectively. Laparoscopic appendicectomy was performed in 93.5% of patients with a conversion rate of 4.6%. NAR-SDC was 10.2% and NAR-STC was 25.8%. NAR was significantly higher in females than males (39.4% versus 11.1%; p-value 0.0001). Patients with NA were younger (p-value 0.0001), had lower mean total WBC (p-value 0.014), CRP (p-value 0.0001) and total serum bilirubin (p-value 0.0001) levels on admission. Conclusion NA is still a major problem in the management of patients with acute right lower abdominal pain. Our NAR compared favourably with reported rates. Female gender, duration of symptoms more than three days, and lower total WBC were independent predictors of NA.

Abstract
BACKGROUND Acute appendicitis in children is the most common condition requiring urgent evaluation and surgery in the emergency department. At times, despite the appendix being seen on ultrasound (US), there can be discrepancy as to whether a patient has clinical appendicitis. Secondary findings suggestive of appendicitis can be helpful in identifying and evaluating these children. OBJECTIVE The aim of this study was to determine if specific US findings and/or laboratory results are predictive of appendicitis in children with a visualized appendix on US. METHODS A prospective study was conducted on children (birth to 18 years) presenting to the pediatric emergency department with suspected appendicitis who underwent right-lower-quadrant US. Ultrasound findings analyzed appendix diameter, compressibility, increased vascularity, presence of appendicolith, inflammatory changes, right-lower-quadrant fluid near the appendix, lower abdominal fluid, tenderness during US, and lymph nodes. Diagnosis was confirmed via surgical pathology. RESULTS There were 1252 patients who enrolled, 60.8 (762) had their appendix visualized, and 39.1 (490) did not. In children where the appendix was seen, 35.2% (268) were diagnosed with appendicitis. Among patients with a visualized appendix, the likelihood of appendicitis was significantly greater if the appendix diameter was 7 mm or greater (odds ratio [OR], 12.4; 95% confidence interval [CI], 4.7-32.7), an appendicolith was present (OR, 3.9; 95% CI, 1.5-10.3), inflammatory changes were seen (OR, 10.2; 95% CI, 3.9-26.1), or the white blood cell (WBC) count was 10,000/μL (OR, 4.8; 95% CI, 2.4-9.7). A duration of abdominal pain of 3 days or more was significantly less likely to be associated with appendicitis (OR, 0.3; 95% CI, 0.08-0.99). The absence of inflammatory changes, WBC count of less than 10,000/μL, and appendix diameter of 7 mm or less had a negative predictive value of 100%. CONCLUSIONS When the appendix is seen on US but diagnosis of appendicitis is questioned, the absence of inflammatory changes, WBC count of less than 10,000/μL, and appendix diameter of 7 mm or less should decrease suspicion for appendicitis.

Abstract
Laparoscopic appendectomy is the preferred operative method for acute appendicitistreatment. In terms of complicated appendicitis it can be effective in hands of an experiencedlaparoscopist that overwhelmed the learning curve for the method. Aim: Тhis retrospectivestudy examines whether the operative time for laparoscopic appendectomy for complicatedappendicitis is shortened after mastering the learning curve. Material and methods: A totalnumber of 196 patients were operated for the diagnosis of acute appendicitis, of whom 77were diagnosed with complicated appendicitis. They were subsequently divided in two groups(laparoscopic and open). Operative time in both groups was measured and the conversionand postoperative complications were noted. Results: Conversion rate was 2.3%. Operativetime was shorter in the laparoscopic group (67.4 ± 22.9 vs. 77.9 ± 17.9 minutes; p = 0.033).Overall postoperative morbidity was 25.97% with wound infection present only in the opengroup (p = 0.018). Intraabdominal abscess occurred in one patient from the laparoscopicgroup (0.38%). Length of hospital stay was shorter in the laparoscopic group (4.3 ± 2.2 vs. 5.7 ± 2.1, p = 0.0052).

Abstract
Purpose of Review Sepsis is a leading cause of death worldwide. Groundbreaking international collaborative efforts have culminated in the widely accepted surviving sepsis guidelines, with iterative improvements in management strategies and definitions providing important advances in care for patients. Key to the diagnosis of sepsis is identification of infection, and whilst the diagnostic criteria for sepsis is now clear, the diagnosis of infection remains a challenge and there is often discordance between clinician assessments for infection. Recent Findings We review the utility of common biochemical, microbiological and radiological tools employed by clinicians to diagnose infection and explore the difficulty of making a diagnosis of infection in severe inflammatory states through illustrative case reports. Finally, we discuss some of the novel and emerging approaches in diagnosis of infection and sepsis. Summary While prompt diagnosis and treatment of sepsis is essential to improve outcomes in sepsis, there remains no single tool to reliably identify or exclude infection. This contributes to unnecessary antimicrobial use that is harmful to individuals and populations. There is therefore a pressing need for novel solutions. Machine learning approaches using multiple diagnostic and clinical inputs may offer a potential solution but as yet these approaches remain experimental.

Abstract
Total serum bilirubin and other biochemical parameters have been associated with acute appendicitis, mainly in complicated cases. The present study aimed to evaluate the role of biochemical parameters in the diagnosis of acute appendicitis, and to further investigate the role of bilirubin as a diagnostic marker irrespective of the severity of the pathology. All recorded cases of appendicectomies in a 1-year period in a single institution were reviewed. The median values of white cell count, C-reactive protein and total serum bilirubin on admission were associated with final histology, and their respective rates of abnormal and normal values were compared between patients who were proven to have negative histology and patients who were proven to have acute appendicitis. A total of 300 patients were studied. Median total serum bilirubin, white cell count and C-reactive protein on admission were significantly associated with acute appendicitis (P<0.001). Respective rates of normal and abnormal values were significantly associated with final histology (P<0.001). Total serum bilirubin demonstrated higher specificity (0.88) but lower sensitivity (0.26) and diagnostic accuracy (0.40) for acute appendicitis. In conclusion, total serum bilirubin on admission should be considered in the diagnostic workup to confirm rather than exclude appendicitis, without focusing on subgroups of specific severity of the disease. White cell count and C-reactive protein may also contribute to the diagnostic work-up, although with limited accuracy.

[PMID: 33712329 DOI: 10.1016/j.asjsur.2021.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 01/27/2021] [Accepted: 02/21/2021] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND /Objective: Ischemia is a leading cause of morbidity in Mechanical Intestinal Obstruction (MIO) in which the timing of decisions of whether to proceed to surgical or conservative treatment is critical in emergency departments (ED). While advanced technological options are available, patients may be negatively affected by the application of contrast agents or radiation. The use of ultrasound is limited because of the air in the intestines does not allow a good field of vision. While biomarkers can be considered as a good alternative option at this point. In the present study we examine the effect of hemogram and blood gas parameters on early surgical decision-making in MIO patients. METHOD Involved in this observational prospective study were 264 patients diagnosed with MIO who presented to the Department of Emergency Medicine, Ataturk Research and Training Hospital, Katip Celebi University between February 2018 and February 2019. Contrast-enhanced tomography (CECT) and laboratory results of the patients were recorded. Pathology reports of the patients who underwent surgery were collected. Laboratory data were analyzed by comparing CECT and pathology reports. RESULTS In a ROC analysis of the laboratory values of the patients who were diagnosed with ileus, the sensitivity was calculated as 80% and the specificity was 57.7 in values above WBC>10.75 (109/L), 96.6%, and the specificity was 31.1% in N/L > 2.9. For intestinal ischemia, the cut-off values were WBC> 12.6 and N/L > 3.2, Lactate >2.8 mmol/L and B.E < -3.6 mmol/L. CONCLUSION Diagnoses of ileus are based on the results examinations and imaging methods. More data are needed to support decisions on the timing of surgery in ED. WBC, N/L, Lactate and Base Excess indicate an ischemic segment. When the parameters are evaluated together, they strongly support early surgical decision-making regarding the treatment of intestinal ischemia.

Abstract
Background Improved diagnostic biomarkers are required for acute appendicitis. The circulating fibrocyte percentage (CFP) is increased in inflammatory states, but has not been studied in acute appendicitis. This study aimed to determine CFP in acute appendicitis and compare diagnostic accuracy with standard serological biomarkers. Methods A prospective cohort study was carried out between June 2015 and February 2016 at University Hospital Limerick. The CFP was determined by dual‐staining peripheral venous samples for CD45 and collagen I using fluorescence‐activated cell sorting, and correlated with histopathological diagnoses. The accuracy of CFP in determining histological acute appendicitis was characterized and compared with the white cell count, C‐reactive protein concentration, neutrophil count, lymphocyte count and neutrophil : lymphocyte ratio. Results Of 95 adults recruited, 15 were healthy individuals and 80 had suspected appendicitis at presentation. Forty‐six of these 80 patients had an appendicectomy, of whom 34 had histologically confirmed appendicitis. The CFP was statistically higher in patients with pathologically proven acute appendicitis than in healthy controls (median 6·1 (i.q.r. 1·6–11·6) versus 2·3 (0·9–3·4) per cent respectively; P = 0·008). The diagnostic accuracy of CFP, as determined using the area under the receiver operating characteristic (ROC) curve, was similar to that of standard biomarkers. In multinomial regression analysis, only raised CFP was retained as an independent prognostic determinant of acute appendicitis (odds ratio 1·57, 95 per cent c.i. 1·05 to 2·33; P = 0·027). Conclusion The CFP is increased in histologically confirmed acute appendicitis and is as accurate as standard serological biomarkers in terms of diagnosis.

Abstract
To determine which factor is associated with presence of fat stranding sign for acute appendicitis on computed tomography (CT).This study reviewed the CT imaging of adults with proven acute appendicitis at a single center from January 1, 2015 to December 31, 2019. Logistic regression models were used to investigate the association between clinical characteristics and fat stranding sign. Receiver operating characteristic (ROC) curve analysis was used to determine the cutoff value that helped predict the presence of fat stranding on CT.In total, 413 patients were included. Age of ≥40 years (OR: 3.10; 95% CI, 2.02-4.74; P < .0001), body mass index of ≥23 kg/m (OR: 2.86; 1.89-4.34; P < .0001), white blood cell count of ≥10,000/μl (OR: 1.77; 1.05-2.99; P = .0316), and C-reactive protein level of ≥2.4 mg/dl (OR: 3.17; 1.97-5.08; P < .0001) were significant factors predicting fat stranding on CT. The ROC analysis with above 4 factors showed an area under the curve of 0.76 (0.71-0.80).Body habitus, advanced age, and elevated inflammatory marker levels were independent in predicting fat stranding for patients with acute appendicitis.

Abstract
A 30-year-old man with a history of severe right iliac fossa pain was referred to the surgical emergency unit. His symptoms began 3 days prior as mild, non-specific abdominal pain which progressively localised to the right iliac fossa and worsened in severity. Investigations were suggestive of acute appendicitis, and therefore a laparoscopic appendicectomy was planned. Laparoscopy revealed a thickened, necrotic appendix with a mass at the base of the appendix, in keeping with the appearance of an appendiceal malignancy. Subsequently a right hemicolectomy was performed. Histology revealed active chronic inflammation and granulomas highly suggestive of appendiceal Crohn's disease. Since, the patient has made a good recovery and presently shows no further signs of Crohn's disease. This case is demonstrative of one of many rare findings on histological examination of the appendix. It emphasises the need for a wide differential when investigating right iliac fossa pain.

Abstract
AIM The differential diagnosis of paediatric patients admitted to the emergency department presenting with acute abdominal pain may be difficult. This study aims to investigate the diagnostic value of ischaemia-modified albumin (IMA) in the differential diagnosis of acute abdominal pain in children and in distinguishing surgical from non-surgical cases. METHODS The study was conducted with a total of 152 subjects who provided informed consent, including 112 patients admitted to the paediatric emergency department and paediatric surgical clinic and 40 healthy control subjects. Blood samples were collected after initial examination to determine IMA, white blood cell (WBC) and C-reactive protein (CRP) values. RESULTS Mean IMA values of patients with acute appendicitis (AA), perforated appendicitis (PA) and non-specific abdominal pain were significantly higher compared to the control group. Mean IMA values of the AA and PA cases were also significantly higher compared to the group with non-specific abdominal pain. No significant difference was determined in mean IMA between the AA and PA groups. WBC and CRP levels of the AA and PA groups were significantly higher compared to the group with non-specific abdominal pain. CONCLUSION Our study shows that IMA, together with WBC and CRP, may be a biomarker capable of assisting the differential diagnosis of acute abdominal pain in children and distinguishing surgical from non-surgical cases.

Abstract
Introduction The evaluation of patients with suspected appendicitis strives to identify all patients with presenting symptoms while minimizing negative appendectomy rate. The aim of the study was to identify the optimal combination of clinical and laboratory parameters that should facilitate the emergency department surgeon’s definite decision. Materials and methods The study group comprised 120 patients with suspicion of acute appendicitis (AA). In 60 patients the AA diagnosis was confirmed intraoperatively and by histological analysis. Clinical parameters included: appetite, vomiting, diarrhea, dysuria, signs of localized peritonitis and pain migration. Measured laboratory parameters were: C-reactive protein (CRP), complete blood count (CBC) and the urine test strip. Results The control group of patients were more likely to present following symptoms: no changes in appetite (P < 0.001), diarrhea (P = 0.009) and dysuria (P = 0.047). CRP and white blood cell count (WBC) were significantly higher in the group with confirmed AA compared to the control group (44.7 vs. 6.6, and 13.6 ± 3.9 vs. 9.0 ± 3.4, respectively; P < 0.001). The multivariate logistic regression analysis identified lack of appetite (P = 0.013), absence of diarrhea (P = 0.004), and positive finding of signs of localized peritonitis (P = 0.013), as well as WBCs (P < 0.001) and negative urine test strip results (P = 0.009) as statistically significant predictors of AA. The highest percentage of correctly classified cases (82%) was achieved by combination of common clinical exam and basic inexpensive laboratory parameters (WBCs and urine test strip). Conclusions Acute appendicitis in the emergency setting may be successfully ruled in based on elevated WBCs and negative urine test strip in combination with signs of localized peritonitis, lack of appetite and absence of diarrhea. Since CRP did not contribute to the overall diagnostic accuracy, its use in AA diagnostic protocols is of no value.

Abstract
INTRODUCTION The present study evaluates the predictive value of such markers as ischemia-modified albumin (IMA), malondialdehyde (MDA) and glutathione peroxide (GSH-Px), in addition to parameters associated with inflammation, oxidative stress and ischemia, playing roles in the pathology of acute appendicitis (AA), including c-reactive protein (CRP), procalcitonin (PCT) and complete blood count (CBC) parameters and their ratios, for the diagnosis of AA in adults. MATERIAL AND METHODS The study included 51 patients with histologically confirmed appendicitis and 45 healthy controls who referred to the emergency care unit between January and June 2018. The appendicitis cases were classified into two groups, as complicated and non-complicated, based on postoperative pathological investigations. RESULTS Of all the appendicitis cases, 68.5% (n = 35) were non-complicated and 31.4% (n = 16) were complicated. IMA (positive LR = 3.0, negative LR = 0.1), GSH-Px (positive LR = 0.5, negative LR = 1.8), MDA (positive LR = 1.8, negative LR = 0.6), CRP (positive LR = 7.2, negative LR = 0.2), PCT (positive LR = 0.7, negative LR = 1.3), WBC (positive LR = 2.9, negative LR = 0.3), neutrophil-lymphocyte ratio (positive LR = 3.2, negative LR = 0.1) thrombocyte lymphocyte ratio (positive LR = 1.6, negative LR = 0.5) and IMA/albumin ratio (positive LR = 3.3, negative LR = 0.1) levels in the appendicitis cases were evaluated by a characteristic receiver operating characteristic (ROC) curve. In addition, IMA levels were significantly higher in the complicated cases (0.40 ± 0.05 AbsU) than in the non-complicated cases (0.29 ± 0.04 AbsU) (p < 0.0001). CONCLUSION Our results showed that IMA (negative LR = 0.1), CRP (positive LR = 7.2, negative LR = 0.2), NLR (negative LR = 0.1) and IMA/albumin ratio (negative LR = 0.1) can serve as important diagnostic biomarkers for AA patients. We therefore believe that before clinically confirming an AA diagnosis, these parameters may be used as diagnostic tools in addition to CBC parameters, CRP levels and radiological imaging studies.

Abstract
RATIONALE Acute appendicitis is one of the most common causes of acute abdomen in children, yet it is difficult to diagnose in young children because its clinical manifestations may be atypical. Here, 3 atypical clinical cases associated with appendicitis in children are reported. PATIENT CONCERN The 1st case corresponds to a 5-year-old male patient who presented with abdominal discomfort, intermittent fevers, and vomiting, have increased white blood cell (WBC) count and C-reactive protein (CRP). The second case is a 7-year-old male patient who began with intermittent fevers and lower quadrant abdominal pain, showing increased WBC count and CRP. The 3rd case corresponds to a 7-year-old female patient who presented with intermittent fevers, abdominal pain, and forebreast discomfort, demonstrating increased WBC count and CRP. DIAGNOSES Abdominal computed tomography (CT) scan presented data suggestive of enlarged appendix in diameter, and stercolith, corroborated through surgery. INTERVENTION Two patients were treated by appendectomy, and 1 patient was treated conservatively with antibiotics. OUTCOMES Three patients were treated successfully. At 3-month follow-up, the patients had no complaints of discomfort with no relapse of appendicitis. LESSONS Due to atypical symptoms of children, the diagnosis of appendicitis is often delayed, suggesting that the clinicians should be aware of this disease when encountering gastroenteritis patients with elevated WBC and CRP. Furthermore, abdominal CT scan should be taken into consideration when patients showed high level of WBC and CRP, whose appendix is not seen on ultrasound.

Abstract
INTRODUCTION While patients with acute uncomplicated appendicitis may be treated conservatively, those who suffer from complicated appendicitis require surgery. We describe a logistic regression equation to calculate the likelihood of acute uncomplicated appendicitis and complicated appendicitis in patients presenting to the emergency department with suspected acute appendicitis. MATERIALS AND METHODS A cohort of 895 patients who underwent appendicectomy were analysed retrospectively. Depending on the final histology, patients were divided into three groups; normal appendix, acute uncomplicated appendicitis and complicated appendicitis. Normal appendix was considered the reference category, while acute uncomplicated appendicitis and complicated appendicitis were the nominal categories. Multivariate and univariate regression models were undertaken to detect independent variables with significant odds ratio that can predict acute uncomplicated appendicitis and complicated appendicitis. Subsequently, a logistic regression equation was generated to produce the likelihood acute uncomplicated appendicitis and complicated appendicitis. RESULTS Pathological diagnosis of normal appendix, acute uncomplicated appendicitis and complicated appendicitis was identified in 188 (21%), 525 (59%) and 182 patients (20%), respectively. The odds ratio from a univariate analysis to predict complicated appendicitis for age, female gender, log2 white cell count, log2 C-reactive protein and log2 bilirubin were 1.02 (95% confidence interval, CI, 1.01, 1.04), 2.37 (95% CI 1.51, 3.70), 9.74 (95% CI 5.41, 17.5), 1.57 (95% CI 1.40, 1.74), 2.08 (95% CI 1.56, 2.76), respectively. For the same variable, similar odds ratios were demonstrated in a multivariate analysis to predict complicated appendicitis and univariate and multivariate analysis to predict acute uncomplicated appendicitis. CONCLUSIONS The likelihood of acute uncomplicated appendicitis and complicated appendicitis can be calculated by using the reported predictive equations integrated into a web application at www.appendistat.com. This will enable clinicians to determine the probability of appendicitis and the need for urgent surgery in case of complicated appendicitis.

C-reactive protein expression in adipose tissue of children with acute appendicitis. Pediatr Res 2018; 84:564-567. [PMID: 29991774 DOI: 10.1038/s41390-018-0091-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2017] [Revised: 04/12/2018] [Accepted: 06/01/2018] [Indexed: 11/08/2022]
Abstract
OBJECTIVE The aim of this study is to gain insights into the role of visceral adipose tissue as a source of C-reactive protein (CRP) in acute inflammation and to explore the potential relationship of CRP expression with the severity of appendicitis. METHODS A total of 20 pediatric patients undergoing appendectomy were included in the study. Patients were divided into two groups according to appendicitis severity (uncomplicated and complicated). CRP levels were measured in visceral fat samples by western blotting, as well as in serum by biochemical testing. RESULTS CRP was found to be expressed in visceral adipose tissue. The adipose tissue of patients with complicated appendicitis showed significantly higher CRP levels (p = 0.002) compared to patients with uncomplicated appendicitis. These results mirrored the CRP values obtained in serum (p = 0.018). CONCLUSION In childhood, visceral adipose tissue is a source of CRP in acute inflammation, and its expression is potentially associated with the severity of local inflammation.

Abstract
Objectives Diagnosis of pediatric patients presenting to the Emergency Department with acute abdominal pain is not always easy. The purpose of this study was to investigate the effectiveness of irisin, a peptide hormone with reactivity shown in the appendix and neutrophils, in the differential diagnosis of pediatric patients with acute abdominal pain. Methods 162 subjects consenting to participate, including 112 patients presenting to the Pediatric Emergency and Pediatric Surgery clinics with acute abdominal pain and 50 controls, were enrolled in the study. Blood was collected from all patients following initial examination for irisin, WBC, and CRP investigation. Results Mean irisin levels in cases of acute appendicitis (AA) and perforated appendicitis (PA) were statistically significantly higher compared to nonspecific abdominal pains and the control group. No statistically significant difference was observed in irisin levels between AA and PA cases. WBC and CRP levels were also significantly higher in cases of AA and PA compared to nonspecific abdominal pains. Conclusions Differential diagnosis of acute abdominal pains in children and deciding on surgery are a difficult and complex process. Our study shows that irisin can be a useful biomarker in differentiating AA and PA from other acute abdominal pains in children.

Abstract
Background Appendicitis is one of the most common surgical emergency in general surgical practices. Early and prompt diagnosis is necessary to avoid life-threatening complications associated with it. The diagnosis is mainly clinically aided by imaging techniques. The physiological obstruction of the bile flow associated with appendicular pathology leads to hyperbilirubinemia, which can be used as a predictive factor of appendicular perforation. Method This prospective study was conducted in the department of general surgery in Madras Medical College and Rajiv Gandhi Government Hospital, Chennai, from January 2012 to November 2012. A total of 378 patients with the features of acute appendicitis or appendicular perforation admitted in the emergency surgical ward were included. Results Out of 378 of the study population, 18% had appendicular perforation and 82% had acute appendicitis. Out of 67 perforations, 60 patients have hyperbilirubinemia (90%) whereas out of 311 patients with appendicitis, only 89 (29%) of them had elevated bilirubin. Hyperbilirubinemia with a cutoff point of 0.9 mg% for appendicitis patients has a sensitivity of 89.6%, specificity of 71.4%, a positive predictive value of 27%, and a negative predictive value of 96.9%. Hyperbilirubinemia with a cutoff point of >1.3 mg% for appendicular perforation has a sensitivity of 80%, specificity of 89%, a positive predictive value of 93%, and a negative predictive value of 96%. Conclusions Hyperbilirubinemia with bilirubin levels more than 1.3 mg% are highly predictive of appendicular perforation and, hence, aid in prompt diagnosis. This can be combined with a clinical diagnosis and imaging for an accurate and precise diagnosis.

Abstract
Ultrasound (US) and laboratory testing are initial diagnostic tests for acute appendicitis. A diagnostic dilemma develops when the appendix is not visualized on US. Objective: To determine if specific US findings and/or laboratory results predict acute appendicitis when the appendix is not visualized. Methods: A prospective study was conducted on children (birth-18 yrs) presenting to the pediatric emergency department with suspected acute appendicitis who underwent right lower quadrant US. Children with previous appendectomy, US at another facility, or eloped were excluded. US findings analyzed: inflammatory changes, right lower quadrant and lower abdominal fluid, tenderness during US exam and lymph nodes. Diagnoses were confirmed via surgical pathology. Results 1252 subjects were enrolled, 60.8% (762) had appendix visualized and 39.1% (490) did not. In children where the appendix was not seen, 6.7% [33] were diagnosed with appendicitis. Among patients with a non-visualized appendix, the likelihood of appendicitis was significantly greater if: inflammatory changes in the RLQ (OR 18.0, 95% CI 4.5-72.1), CRP >0.5 mg/dL (OR 2.64, 95% CI 1.0-6.8), or WBC > 10 (OR 4.36, 95% CI 1.66-11.58). Duration of abdominal pain >3 days was significantly less likely associated with appendicitis in this model (OR 0.34, 95% CI 0.003-0.395). Combined, the absence inflammatory changes, CRP < 0.5 mg/dL, WBC < 10, and pain, ≤3 days had a NPV of 94.0%. Conclusion When the appendix is not visualized on US, predictors for appendicitis include the presence of inflammatory changes in the RLQ, an elevated WBC/CRP and abdominal pain <3 days.

Abstract
BACKGROUND The C reactive protein (CRP) is one of the most accurate inflammatory markers in acute appendicitis (AA). Obesity leads to a pro-inflammatory state with increased CRP, which may interfere with the interpretation of this laboratory test in AA. AIM To assess sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of CRP in patients with AA and their correlation to body mass index (BMI) and body fat composition. METHOD This is a retrospective study based on clinical records and imaging studies of 191 subjects with histopathologically confirmed AA compared to 249 controls who underwent abdominal computed tomography (CT). Clinical and epidemiological data, BMI, and CRP values were extracted from medical records. CT scans were assessed for AA findings and body composition measurements. RESULTS CRP values increased according to patients' BMI, with varying sensitivity from 79.78% in subjects with normal or lean BMI, 87.87% in overweight, and 93.5% in individuals with obesity. A similar pattern was observed for NPV: an increase with increasing BMI, 69.3% in individuals with normal or lean BMI, 84.3% in overweight, and 91.3% in individuals with obesity. There was a positive correlation between CRP and visceral fat area in patients with AA. CONCLUSIONS Variations exist for sensitivity, specificity, PPV, and NPV values of CRP in patients with AA, stratified by BMI. An increase in visceral fat area is associated with elevated CRP across the BMI spectrum.

Abstract
Introduction Clinical diagnosis of acute appendicitis still remains a problem. Delays in diagnosis of acute appendicitis may cause perforation and septic peritonitis which result in increasing morbidity and mortality. The aim of this study was to determine the sensitivity, specificity and the diagnostic value of total serum bilirubin levels as a predictor of acute appendicitis. Methods In this cross-sectional study, patients who underwent appendectomy with the diagnosis of acute appendicitis from April 2012 to March 2013 at Emam Reza Hospital in Mashhad (Iran) were enrolled. Serum bilirubin-Total and Direct-, were measured. Then based on the final pathologic reports, patients were categorized into five groups of normal appendix, chronic inflammatory changes, acute appendicitis, gangrenous and/or necrotic changes, and perforated appendicitis. Independent sample t-test, ANOVA, and Chi-square test were used for data analysis by SPSS version 16. Results There were 174 patients studied, (117 male, 57 female) with a mean age of 27.15±0.7 years. All of the patients had rebound tenderness; 75.3% had nausea, 58.6% had anorexia and 21.3% had fever. The histological reports of all patients showed 76.4% acute appendicitis. Analyzing p-values for SGPT, SGOT, WBC was (p=0.903) and differential count was (p=0.959). The study showed no significant difference between the pathological groups. However, there were no significant differences in serum total bilirubin levels between the pathological groups. Total bilirubin showed sensitivity of 48% and specificity of 61% in the diagnosis of acute appendicitis. Total serum bilirubin more than 0.85 mg/dl was the cut-off value with the best performance for diagnosis of appendicitis. Conclusion Bilirubin levels are reliable, sensitive and specific to diagnosis and a prediction of complicated appendicitis.

Abstract
Concerns about radiation exposure have led to a decrease in the use of computed tomography in suspected appendicitis, with increased reliance on ultrasound. Children with suspected appendicitis should be risk stratified using a combination of clinical signs and symptoms, white blood cell count, and ultrasound in order to guide further evaluation and management. Magnetic resonance imaging is a promising imaging modality but remains costly. Ongoing research is evaluating the role of nonoperative management in children with confirmed appendicitis.

Abstract
BACKGROUND Elevated levels of circulating plasma and urine leucine-rich-2-glycoprotein-1 (LRG1) protein has been found in patients with acute appendicitis (AA) and may be useful for diagnosis. This study aimed to investigate whether combined tests including circulating LRG1 mRNA levels improve the early diagnosis of AA. METHODS Between December 2011 and October 2012, a prospective study was conducted on patients aged 18years or older presenting to the ED with acute abdominal pain (<7days of symptom onset). Levels of whole blood LRG1 mRNA and plasma LRG1 protein taken from these patients within 24h of arrival (mean 12.4h) were analyzed. The primary outcome was AA. RESULTS Eighty-four patients (40 (47.6%) with AA and 44 (52.4%) without AA; mean age 35years; 41.6% males) were recruited. Median whole blood LRG1 mRNA and plasma LRG1 levels were higher in AA patients than in non-AA. Of 40 AA patients, 13 (32.5%) were diagnosed as complicated AA. In ROC analysis of LRG1 mRNA (normalized to GAPDH), LRG1 protein and Alvarado score for discriminating AA and non-AA, the areas under the curve (AUC) were 0.723, 0.742 and 0.805 respectively. The AUC of combination of normalized LRG1 mRNA, LRG1 protein and Alvarado score was 0.845. CONCLUSION A combination of modified whole blood LRG1 mRNA levels, plasma LRG1 protein and Alvarado score at the ED may be useful to diagnose simple and complicated AA from other causes of abdominal pain.

Abstract
Background Acute appendicitis is the most common surgical emergency and can represent a challenging diagnosis, with a negative appendectomy rate as high as 20 %. This review aimed to evaluate the clinical utility of individual biomarkers in the diagnosis of appendicitis and appraise the quality of these studies. Methods A systematic review of the literature between January 2000 and September 2015 using of PubMed, OvidMedline, EMBASE and Google Scholar was conducted. Studies in which the diagnostic accuracy, statistical heterogeneity and predictive ability for severity of several biomarkers could be elicited were included. Information regarding costs and process times was retrieved from the regional laboratory. European surgeons blinded to these reviews were independently asked to rank which characteristics of biomarkers were most important in acute appendicitis to inform a cost–benefit trade-off. Sensitivity testing and the QUADAS-2 tool were used to assess the robustness of the analysis and study quality, respectively. Results Sixty-two studies met the inclusion criteria and were assessed. Traditional biomarkers (such as white cell count) were found to have a moderate diagnostic accuracy (0.75) but lower costs in the diagnosis of acute appendicitis. Conversely, novel markers (pro-calcitonin, IL 6 and urinary 5-HIAA) were found to have high process-related costs including analytical times, but improved diagnostic accuracy. QUADAS-2 analysis revealed significant potential biases in the literature. Conclusion When assessing biomarkers, an appreciation of the trade-offs between the costs and benefits of individual biomarkers is needed. Further studies should seek to investigate new biomarkers and address concerns over bias, in order to improve the diagnosis of acute appendicitis.

Abstract
BACKGROUND Diagnostic approach for complicated appendicitis is still controversial. We planned this study to analyze preoperative laboratory markers that may predict complications of appendicitis. METHODS Patients who underwent appendectomy were retrospectively recruited. They were divided into complicated appendicitis and non-complicated appendicitis groups and their preoperative laboratory results were reviewed. RESULTS A total of 234 patients were included. Elevated international normalized ratio (INR) and serum C-reactive protein (CRP) were associated with complicated appendicitis (p = 0.001). On ROC curve analysis, area under the curve (AUC) of CRP and INR were 0.796 and 0.723, respectively. CONCLUSIONS INR and CRP increased significantly in patients with complicated appendicitis. Further studies evaluating INR and CRP in patients undergoing conservative management for appendicitis are required.

Abstract
BACKGROUND Acute appendicitis is a common presentation in surgical assessment units and appendectomy accounts for a large number of emergency operations in the UK. Histopathological examination of the appendectomy specimens are routinely carried out. The aim of this study is to correlate the histological findings of appendectomy specimens with the clinical diagnosis of acute appendicitis. METHODS This is a retrospective analysis of 238 appendectomies carried out in a single UK center between January and December 2013. The Histopathology reports of appendectomy specimens were retrieved. RESULTS A total of 238 appendectomies were performed during the study period. The mean age of the patients was 32 years (range, 7-81 years). Adult patients (>16 years) represented 79.4% of the study population. The female sex accounted for 46.6% of all the patients. Of the 238 resected appendix, 211 (88.7%) had histopathology findings consistent with appendicitis. Approximately 1.7% of the 238 specimens were abnormal pathologies other than inflammation of the appendix. The negative appendectomy (normal appendix on histology) rate was 11.3%. The female sex accounted for 59.1% of the negative appendectomies. Adults (>16 years) represented 77.8% of the negative appendectomies. CONCLUSIONS The observed high rates of negative appendectomy in the female sex can be reduced by utilizing combined clinical assessment and diagnostic imaging modalities. The findings of abnormal pathologies on histopathological examination of the appendix which could potentially impact on the management of the patients justify the current practice of routine histopathological examination of resected appendix.

Abstract
UNLABELLED Appendicitis is a common clinical diagnosis aided by biochemical, haematological and radiological investigations. The role of some investigations, such as bilirubin, is controversial but could indicate complicated appendicitis. Accurate diagnosis enables prioritisation of patients on operating lists and a possible reduction in unnecessary investigations. METHODS This is a retrospective cohort study of 1347 patients who underwent appendicectomy. Statistical analysis of serum bilirubin levels was performed according to histological classification of appendicitis. RESULTS Mean serum bilirubin levels; perforated/gangrenous appendicitis 20.5 mg/L (SD 12.6), inflamed appendicitis mean 17.5 mg/L (SD CI 11.1), normal appendix mean 12.6 mg/L (7.0). Kruskal-Wallis indicated bilirubin levels were significantly different (H=128.87, df=4, p<.001) between histological groups, and a post hoc analysis with Bonferroni adjustment showed perforated/gangrenous to be significantly higher than all other groups (p<.001). Binary logistic regression combining White Cell Count (WCC) level, C-Reactive Protein (CRP) and Bilirubin levels gave a sensitivity and specificity of .69 with AUROC=.766 (std error .015) for gangrenous/perforated. Assessment according to clinical relevance showed only 30.4% of patients with an abnormally raised bilirubin had gangrenous/perforated appendicitis. CONCLUSIONS Serum bilirubin does not independently predict perforation/gangrenous appendicitis. Statistical analysis showed differences in mean bilirubin between histological groups however this did not relate to clinical significance as bilirubin levels were still within normal clinical limits. Diagnosis of complicated appendicitis should be made on clinical grounds, with utilization of biochemical/haematological investigations, but there should not be independent reliance on investigations such as bilirubin.
