BMC Gastroenterol 2023; 23:444. [PMID: 38104067 PMCID: PMC10725578 DOI: 10.1186/s12876-023-03091-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 12/12/2023] [Indexed: 12/19/2023] Open
Abstract
BACKGROUND Acute appendicitis (AA) is among the most common nontraumatic indications for emergent abdominal surgical procedures. However, accurately diagnosing all cases can be challenging, physical examination, biochemical markers, and imaging techniques can sometimes be insufficient. This study aimed to (a) compare the mean platelet volume (MPV) and total white blood cell count (TWBCs) in patients with or without histological evidence of an inflamed appendix and (b) determine the positive predictive value, negative predictive value, sensitivity, and specificity of both MPV and TWBCs as diagnostic biomarkers in the diagnosis of AA. We conducted this research at Omdurman Military Hospital, focusing on patients who presented with symptoms suggestive of AA. MATERIALS AND METHODS An analytical cross-sectional study conducted at Omdurman Military Hospital from December 2020 - December 2021. The study population was patients who presented to our emergency department with symptoms and signs suggestive of AA. Participants were patients operated on as cases of AA. Data variables included sociodemographic characteristics, clinical presentations, intraoperative appendix macroscopic findings, preoperative MPV and total white blood cell count (TWBCs), and postoperative histopathological findings. RESULTS A total of 106 patients were included in this study, with 75 (68.2%) males; half were 10-19 years old. Sixty-three patients (57.3%) had low (< 7.5 fL) MPV, whereas 47 (42.7%) had normal values. Comparing MPV to total white blood cells (TWBCs) revealed that MPV was more sensitive (84.6%) and specific (90%) than TWBCs during the first 24 h of inflammation. However, the TWBCs were more sensitive (97.2%) but less specific (94.7% vs. 100%) after 24 h of onset. CONCLUSION In this study, MPV was lower in patients with AA, while there was an increase in TWBCs. The high sensitivity and specificity of TWBCs and MPV indicated that they form a promising diagnostic marker for AA.

Abstract
BACKGROUND In this retrospective study the effects of the neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), mean platelet volume to platelet count ratio (MPV/PC) values as well as C‑reactive protein (CRP) and procalcitonin (PCT) levels on the severity and mortality in critically ill child trauma cases were evaluated. METHODS A total of 80 trauma cases aged 31 days to 16 years that were followed-up in the pediatric intensive care unit (PICU) were included in the study. The data of the patients on the first day of hospitalization (T1), the median day of intensive care admission (T2), and before discharge or exitus (T3) were analyzed. The cases were divided into three groups according to the injury severity score (ISS) as minor, moderate, and severe. RESULTS Of the 80 cases 59 (73.75%) were male and 21 (26.25%) were female. The mean age of all the cases was 54.5 ± 47.8 months, and the mean PICU stay was 7.35 ± 6.64 days. Of the cases 19 (23.75%) due to motor vehicle accidents and 61 (76.25%) due to falling from heights were followed-up. The mortality rate was found to be 13.75% (11 cases). The T1, T2 and T3 NLR, MLR, MPV/PC and PCT values did not differ between the groups. The T1 and T2 CRP levels were higher in the moderate trauma group than in the severe trauma group. Also, ISS and pediatric risk of mortality 3 (PRISM-3) scores were higher while the revised injury severity classification version II (RISC II), RISC II survival and Glasgow coma scale (GCS) scores were lower in the nonsurvivors. While the T3 MLR value was lower in nonsurvival cases, the T3 MPV/PC value was found to be higher. CONCLUSION The NLR, MLR, and MPV/PC values do not predict the severity of the trauma in children. In children with severe trauma, low MLR and high MPV/PC values can be used to predict mortality.

Abstract
Our study aims to ascertain the diagnostic value of the Monocyte-lymphocyte ratio (MLR) and red cell distribution width (RDW)-lymphocyte ratio (RLR) by comparing them with other biomarkers in distinguishing patients with and without acute appendicitis (AA). A total of 223 children were recruited in the study conducted according to the Cross-Sectional Study design. Patients under 18 years were assigned to 3 groups; AA, nonspecific abdominal pain (NAP), and a control group. According to the outcome of our research, while C-reactive protein (CRP), white blood cell (WBC), neutrophil count (NEU), neutrophil to lymphocyte ratio (NLR), and MLR had excellent diagnostic power, RLR had acceptable diagnostic power, and platelet to lymphocyte ratio (PLR) had only fair diagnostic power. MLR and NLR, which are simple, inexpensive, and easily accessible parameters, can be recommended to be used together with other biomarkers in diagnosing AA in children.

Mean Platelet Volume in the Diagnosis of Acute Appendicitis in the Pediatric Population: A Systematic Review and Meta-Analysis. Diagnostics (Basel) 2022; 12:diagnostics12071596. [PMID: 35885500 PMCID: PMC9318144 DOI: 10.3390/diagnostics12071596] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 06/26/2022] [Accepted: 06/28/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Mean Platelet Volume (MPV) has been suggested as a biomarker for acute appendicitis (AA) in the adult population. The utility of MPV in pediatric AA remains vague. This systematic review and meta-analysis aimed to systematically summarize and compare all relevant data on MPV as a diagnostic biomarker for AA in children. Methods: Databases were systematically searched using keywords ((mean platelet volume) OR mpv) AND (appendicitis). The inclusion criteria were all comparative studies of MPV in children aged less than 18 years and diagnosed with AA. Two authors independently assessed the methodological quality using the Downs and Black scale. Results: We included fourteen studies in the final meta-analysis; most were retrospective. Eight studies compared the MPV values between AA and non-AA; four studies compared the same between AA and healthy controls; two studies compared the MPV values among all three groups. The estimated heterogeneity among the studies for all outcomes was high and statistically significant. The pooling the data showed no statistically significant difference in MPV (weighted mean difference (WMD) = −0.42, 95% CI = (−1.04, 0.20), p = 0.19) between AA and healthy controls or AA and non-AA cases (WMD = 0.01, 95% CI = (−0.15, 0.17), p = 0.90). Conclusion: While MPV levels seem to have some utility in adult AA diagnosis, MPV levels should not dictate treatment options in pediatric AA.

Abstract
To explore the value of blood routine examination indexes in the differential diagnosis of immunoglobulin A vasculitis (IgAV) with abdominal involvement and appendicitis in children. Forty-seven patients with IgAV and abdominal involvement, 95 cases with appendicitis, and 48 healthy children were enrolled in this study. Demographic and laboratory data were retrospectively recorded from medical files. The levels of serum percentage of lymphocytes (LYM%), percentage of eosinophils (E%), red cell volume distribution width (RDW) and platelet (PLT) count were higher, while blood cells (WBC) count, percentage of neutrophils (N%), percentage of monocytes (M%), mean platelet volume (MPV), platelet distribution width and C-reactive protein were lower in the group of IgAV with abdominal involvement compared to appendicitis group (P < 0.05). Multivariate logistic regression analysis showed LYM% (odds ratio (OR) = 1.34, P = 0.001) and RDW (OR = 2.96, P = 0.045) were independent risk factors for IgAV with abdominal involvement. N% (OR = 1.270, P = 0.006) and MPV (OR = 51.15, P = 0.042) were independently associated with appendicitis. Using receiver operating characteristic analysis, the optimal cut-off values (sensitivity and specificity) respectively were 42.17% (95.7%, 100.0%) for LYM%, 12.65% (83.0%, 83.2%) for RDW, 61.5% (91.6%, 97.9%) for NE% and 10.1fL (78.9%, 75.4%) for MPV, with the AUC values of 0.989, 0.881, 0.985, 0.810, respectively. Blood routine examination indices, especially the N%, LYM%, RDW, and MPV, can be used for simple differential diagnosis of IgAV with abdominal involvement and appendicitis.

Abstract
BACKGROUND Acute appendicitis (AA), the most common abdominal emergency disease, is one of the most important causes of hospitalization of children. Studies have shown that white blood cell (WBC) count, mean platelet volume (MPV), C‑reactive protein (CRP), and erythrocyte sedimentation rate (ESR) can play an important role in the diagnostic prediction of appendicitis. Therefore, the aim of this study was to evaluate the diagnostic value of WBC count, polymorphonuclear leukocytes (PMNs) percentage, MPV, CRP, and ESR for the diagnosis of AA. METHODS In this study, 100 medical records were reviewed for children referred to the hospital complaining of abdominal pain and who underwent operation with a provisional diagnosis of acute appendicitis based on clinical and laboratory findings. Patients were divided into two groups according to the pathology gold standard method: AA and the other group with acute abdominal pain without appendicitis (AAP). The diagnostic accuracy of WBC, PMNs%, MPV, ESR, and CRP were compared for patients with AA and AAP. RESULTS A total of 100 patients (50 with AA and 50 with AAP) were identified. The sensitivity and specificity of WBC and PMNs% were 78 and 66%, and 76 and 54%, respectively; ESR was 80 and 48%, respectively; and CRP was 82 and 62% (30-89%), respectively. A low specificity (8%) and 70% sensitivity was calculated using the cutoff point of 8.1 fl for MPV. CONCLUSION Our data suggest that children with AA often present with significantly higher WBC count, ESR level, CRP level, PMNs%, and lower MPV level. The results of the study showed that WBC, CRP, and ESR, along with other diagnostic methods, can be useful in diagnosing AA in children. MPV is not effective in the diagnosis of AA due to its specificity; however, a significantly lower level was found in children with AA.

Predictive Value of Red Blood Cell Distribution Width, Mean Platelet Volume and Platelet Distribution Width in Children with Acute Appendicitis. CHILDREN (BASEL, SWITZERLAND) 2021; 8:children8111041. [PMID: 34828754 PMCID: PMC8619955 DOI: 10.3390/children8111041] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 11/02/2021] [Accepted: 11/05/2021] [Indexed: 11/16/2022]
Abstract
Background and Objectives: Acute appendicitis in pediatric patients is one of the most common surgical emergencies, but the early diagnosis still remains challenging. The aim of this study was to determine the predictive value of Red blood cell distribution width (RDW), Mean platelet volume (MPV) and Platelet distribution width (PDW) in children with acute appendicitis. Materials and Methods: This study was a retrospective assessment of laboratory findings (RDW, MPV, PDW) of patients who underwent surgical treatment for acute appendicitis from January 2019 to December 2020. Result: During this period, 223 appendectomies were performed at our Institute. In 107 (43%) cases appendicitis was uncomplicated, while in 116 (46.6%) it was complicated. WBC and RDW/MPV ratio were significant parameters for the diagnosis of acute appendicitis with cut-off values of 12.86 (susceptibility: 66.3%; specificity: 73.2%) and 1.64 (susceptibility: 59.8%; specificity: 71.9%), respectively. WBC and RDW/RBC ratio were independent variables for the diagnosis of complicated appendicitis. The cut-off values were 15.05 for WBC (sensitivity: 60.5%; specificity: 70.7%) and 2.5 for RDW/RBC ratio (sensitivity: 72%; specificity: 52.8%). Conclusions: WBC is an important predictor of appendicitis and complicated appendicitis. RDW, MPV and PDW alone have no diagnostic value in pediatric acute appendicitis or predicting the degree of appendix inflammation. However, the RDW/MPV ratio can be an important predictor of appendix inflammation, with higher values in patients with more severe appendix inflammation. RDW/RBC ratio may be an important predictor of complicated appendicitis.

Abstract
INTRODUCTION Acute appendicitis is one of the most common surgical emergencies worldwide. Clinical scoring system systems have been developed to diagnose acute appendicitis, but insufficient to predict the complication. The amount of serum biomarkers elevates in response to acute inflammation, which could be beneficial for diagnostic tools. Accordingly, a meta-analysis was conducted to evaluate the efficacy of platelet indices, including mean platelet volume (MVP) and platelet distribution width (PDW) as potential biomarkers for the diagnosis of a diagnosis of acute appendicitis. MATERIAL AND METHODS The dataset was defined by searching for articles published until December 2020 from PubMed, EMBASE, Google Scholar and the Cochrane database. The meta-analysis was performed using Review Manager Software version 5.4.1. RESULTS The final analysis was made from 9 studies, including 3124 patients. The results demonstrated that lower MPV values was significantly associated with acute appendicitis (odds ratio (OR) = 0.81, 95% confidence interval (CI) = -1.51 to -0.11, P = 0.02), but not associated with complicated appendicitis by comparing it with the control (OR = -0.13,95% CI = -0.33 to -0.07, P = 0.19) and non-complicated appendicitis groups (OR = -0.13,95% CI = -0.30 to -0.04, P = 0.14). The present study failed to demonstrate the diagnostic value of PDW for the prediction of appendicitis and its complication. CONCLUSION The results of the meta-analysis strongly indicate that a lower MVP values could function as a marker for predicting the acute appendicitis.

Abstract
BACKGROUND To analyze whether clinical and analytical parameters differ according to histopathology in cases of acute appendicitis (AA). METHODS This is a retrospective, observational study including patients (>14 years of age) admitted for suspicion of AA from 1 April 2014 to 31 July 2016. Histopathology was divided into complicated (including perforated and gangrenous AA) and uncomplicated appendicitis (phlegmonous). Sex, age, temperature of patients on admission to the Emergency Department, symptom duration, preoperative white blood cell (WBC) count, neutrophil percentage, mean platelet volume (MPV), platelet distribution width (PDW), C-reactive protein (CRP) and hospital stay were compared in the two groups. RESULTS Three hundred and thirty-five patients were analyzed, and 284 were included. Appendicitis was uncomplicated in 194 (68.3%) and complicated in 90 (31.7%). Age, symptom duration, neutrophil percentage, CRP and hospital stay were higher in the complicated AA group (P < .05). The mean differences between uncomplicated and complicated AA were: age 13.2 years (95% CI: 8.2-18.2), symptom duration 14.1hours (95% CI: 6.3-21.9), neutrophil percentage 5.0% (95% CI: 3.2-6.8), CRP 73.6mg/l (95% CI: 50.0-97.2) and hospital stay 2.2 days (95% CI: 1.4-3.0), with p<0.05 for all these variables. A model based on the preoperative parameters (age, symptom duration, neutrophil percentage and CRP) was calculated to predict the likelihood of complicated AA. The receiver operating characteristic (ROC) of the model had an area under the curve of 0.80 (95% CI 0.75-0.85). CONCLUSION This model is able to diagnose complicated AA without the need for imaging techniques, although it must be validated with prospective analysis.

Platelet indices in patients with acute appendicitis: a systematic review with meta-analysis. Updates Surg 2021; 73:1327-1341. [PMID: 33439467 DOI: 10.1007/s13304-020-00928-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Accepted: 11/11/2020] [Indexed: 02/07/2023]
Abstract
Correlation between blood inflammatory parameters and acute appendicitis (AA) remains controversial. This meta-analysis aims to evaluate whether platelet (PLT) indices including mean platelet volume (MPV), PLT count, and platelet distribution width (PDW) are associated with AA. Pubmed, Embase, and Cochrane Library databases were searched for observational studies published from inception through April 2020 by two independent investigators. Studies reporting associations between platelet indices and AA were selected for inclusion. Standardized mean difference (SMD) and 95% confidence interval (CI) were estimated for continuous outcomes using a DerSimonian-Laird random-effects model. Of 842 records identified, 17 studies with a total of 6793 subjects met our inclusion criteria. Meta-analysis indicated that compared with those in healthy controls, significant decrease in MPV levels was observed in subjects with AA (SMD - 0.34; 95% CI - 0.56 to - 0.12; P = 0.003). Subgroup analyses represented a significant reduction of MPV levels in patients aged ≥ 30 years and non-complicated/non-perforated AA. Due to the small number of studies and patients included in each subgroup, these subgroup analyses need to be interpreted with caution. However, none of the levels of PLT (SMD - 0.13; 95% CI - 0.28-0.012; P = 0.071) or PDW (SMD 0.30; 95% CI - 0.22-0.83; P = 0.257) was seen decrease or increase in subjects with AA. This meta-analysis indicates a significant decrease in MPV levels in patients with AA, which makes MPV have the potential of serving as a biomarker for AA. The associations of other PLT indices with AA need to be further examined.

Abstract
OBJECTIVE Abdominal examination findings in pediatric acute appendicitis (AA) significantly vary by age. Therefore, grading systems have been developed for diagnosing pediatric appendicitis, and laboratory and radiological findings have an important role in this diagnosis. However, there is a need to develop new parameters for diagnosing AA. This study aimed to investigate the diagnostic value of platelet indices in AA. METHODS This retrospective, observational study included 207 pediatric patients who were admitted to the Emergency Department and operated on for AA. The patients were divided into three groups on the basis of their surgical and histopathological findings (non-AA, uncomplicated AA, and complicated AA). RESULTS There was no significant difference in the mean platelet volume/platelet count (MPV/PC) ratio among the groups. The white blood cell (WBC) count and the MPV/PC ratio showed a significant negative relationship (r = -0.239). The specificity for MPV was 61.8% and the sensitivity was 68.8%. Receiver operating curve analysis of WBC and MPV showed significance for diagnosing AA. CONCLUSION There is a negative, but weak, relationship between the WBC count and the MPV/PC ratio. However, the MPV/PC ratio could be a useful parameter for diagnosing pediatric AA according to receiver operating curve analysis.

Abstract
INTRODUCTION There is a tendency toward nonoperative management of appendicitis resulting in an increasing need for preoperative diagnosis and classification. For medical purposes, simple conceptual decision-making models that can learn are widely used. Decision trees are reliable and effective techniques which provide high classification accuracy. We tested if we could detect appendicitis and differentiate uncomplicated from complicated cases using machine learning algorithms. MATERIALS AND METHODS We analyzed all cases admitted between 2010 and 2016 that fell into the following categories: healthy controls (Group 1); sham controls (Group 2); sham disease (Group 3), and acute abdomen (Group 4). The latter group was further divided into four groups: false laparotomy; uncomplicated appendicitis; complicated appendicitis without abscess, and complicated appendicitis with abscess. Patients with comorbidities and whose complete blood count and/or pathology results were lacking were excluded. Data were collected for demographics, preoperative blood analysis, and postoperative diagnosis. Various machine learning algorithms were applied to detect appendicitis patients. RESULTS There were 7244 patients with a mean age of 6.84 ± 5.31 years, of whom 82.3% (5960/7244) were male. Most algorithms tested, especially linear methods, provided similar performance measures. We preferred the decision tree model due to its easier interpretability. With this algorithm, we detected appendicitis patients with 93.97% area under the curve (AUC), 94.69% accuracy, 93.55% sensitivity, and 96.55% specificity, and uncomplicated appendicitis with 79.47% AUC, 70.83% accuracy, 66.81% sensitivity, and 81.88% specificity. CONCLUSIONS Machine learning is a novel approach to prevent unnecessary operations and decrease the burden of appendicitis both for patients and health systems. LEVELS OF EVIDENCE III.

Abstract
Background: Acute appendicitis (AA) is one of the most common causes of abdominal pain requiring surgical intervention. Approximately 20% of AA cases are characterized by complications such as gangrene, abscesses, perforation, or diffuse peritonitis, which increase patients' morbidity and mortality. Diagnosis of AA can be difficult, and evaluation of clinical signs, laboratory index and imaging should be part of the management of patients with suspicion of AA.Methods: This consensus statement was written in relation to the most recent evidence for diagnosis and treatment of AA, performing a literature review on the most largely adopted scientific sources. The members of the SPIGC (Italian Polispecialistic Society of Young Surgeons) worked jointly to draft it. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Chest Physicians (CHEST) for the strength of the recommendations.Results: Fever and migratory pain tend to be present in patients with suspicion of AA. Laboratory and radiological examinations are commonly employed in the clinical practice, but today also scoring systems based on clinical signs and laboratory data have slowly been adopted for diagnostic purpose. The clinical presentation of AA in children, pregnant and elderly patients can be unusual, leading to more difficult and delayed diagnosis. Surgery is the best option in case of complicated AA, whereas it is not mandatory in case of uncomplicated AA. Laparoscopic surgical treatment is feasible and recommended. Postoperative antibiotic treatment is recommended only in patients with complicated AA.

Abstract
Many studies have found correlations between abnormal MPV and clinical reactivity in a variety of diseases. In the present paper, we sought MPV-related neurological diseases that are less frequently reported in the literature. The electronic medical records of 852 neurological patients with mean platelet volume (MPV) measurements (F = 45%, age = 55.7 ± 18.7, 8–104) were searched after the patients had received a diagnosis of a neurological disease (new and old episodes) according to the nine classes of the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10). A set of consecutive statistical methods (i.e., cluster analysis, segmented regression, linear correlation, propensity score matching, and mixed effects Poisson regression) were used to establish a link between MPV and neurological disease. A statistically significant (p < 0.05) relationship with MPV was found only in pain syndrome patients, with seven out of eight clinically diagnosed migraine episodes. With all other ICD-10 classes of neurological diseases, the effect of MPV was found to be nonsignificant (p > 0.05). MPV may implicate a clinical relationship with pain syndrome and migraine episodes. More complex statistics could help analyse data and find new correlations.

Abstract
Introduction: Acute appendicitis is the most common cause of the abdominal pain in surgery. Despite its significant prevalence, the diagnosis is associated with many problems in some cases, which leads to false appendectomy. Objective: The aim of this study was to determine the validity of diagnostic tests of mean platelet volume (MPV) and red cell distribution width (RDW), as a new possible tool in the diagnosis of acute appendicitis. Methods: In this study, all patients who referred to the emergency department of Besat Hospital, Hamadan, Iran, in 2015, with abdominal pain and first impression of acute appendicitis, undergone appendectomy, were evaluated. The diagnostic markers of pre-operative and post-operative pathology and the validity of MPV and RDW were determined in diagnosis of acute appendicitis. Results: Laboratory and clinical data from 438 patients, presenting the signs and symptoms of acute appendicitis with the mean age of 26.51±13.9 years, were examined (55.6% men). The sensitivity, specificity, positive and negative predictive value of MPV in the diagnosis of acute appendicitis were 59.77, 98.66, 99.5 and 34.26 percent, and for the RDW were 57.79, 56.00, 86.07 and 21.98 percent, respectively. The area under the receiver operating characteristic (ROC) curve for RDW and MPV was 0.61and 0.90, respectively. The mean of MPV in patients with normal pathologic outcome was 9.52±1.60 and in patients with acute appendicitis was 7.51±1.22. There was a significant difference between the mean MPV in both groups (p<0.001). The mean of RDW in patients with normal pathology were 13.42±1.97 and 13.05±1.09, in patients with acute appendicitis. There was a significant difference between the mean RDW of the two groups (p=0.009). Conclusion: MPV and RDW indexes have the potential to be used by the surgeons in diagnosis of acute and perforated appendicitis, especially in adults, in order to reduce unnecessary appendectomy, but MPV is more valid in screening acute appendicitis, compared to the RDW.

Abstract
BACKGROUND: The occurrence and early management of acute appendicitis among children are especially important due to the difficult diagnosis and nonspecific symptoms of the disease. Diagnosis of appendicitis in children is very difficult due to similarity of its symptoms to other diseases, and also its self-limiting nature Platelet indexes such as mean platelet volume (MPV) and platelet distribution width (PDW) have been suggested as a biomarker of inflammation. AIM: Therefore, we examined the association of MPV and PDW with acute appendicitis in children. METHODS: This cross-sectional study was conducted on 464 patients with suspected acute appendicitis under the age of 18 years referred to the specialised hospitals of the ten studied provinces between October 2014 and October 2015. All data obtained regarding patient’s lab tests, i.e. platelet count, MPV and PDW and also radiological studies and surgical reports were gathered in datasheets and analysed to evaluate the potential association of platelet levels, mean platelet volume (MPV) and platelet distribution width (PDW) with acute appendicitis RESULTS: Our results showed that the MPV was significantly higher in acute appendicitis in comparison to perforated appendicitis as well as acute gangrenous appendicitis. PDW was significantly higher in acute appendicitis in comparison to perforated appendicitis and acute gangrenous appendicitis. The current project indicated that PDW < 10.05 had a sensitivity of 35% and specificity of 75%, platelet count < 229500 had a sensitivity of 24% and specificity of 75% and MPV < 8.95 had a sensitivity of 70% and specificity of 71%. CONCLUSION: Our study suggested that platelet indexes such as MPV and PDW could significantly correlate with acute appendicitis in pediatric patients. Hence, we believe that both MPV and PDW could use as a simple and low-cost lab test for diagnosing acute appendicitis. Also, this study revealed that the MPV lower than 8.95 could be a novel index for diagnosing acute appendicitis with sensitivity of 70% and specificity of 71%.

Abstract
Introduction The role of whole blood count parameters in the diagnosis of diseases in which inflammatory processes play a role is one of the more frequently mentioned topics in the literature in recent years. Studies of acute appendicitis have also been carried out in this regard, but studies focused on platelet parameters are few and contradictory. We aimed to investigate the role of mean platelet volume (MPV) and platelet distribution width (PDW) in the diagnosis of acute appendicitis. Materials and methods We retrospectively screened the medical records of patients older than 15 years who had an appendectomy from January 2012 to January 2015 at a training hospital in Kocaeli, Turkey. Patients were divided into three groups according to their pathology results: non-appendicitis (Group 1), uncomplicated appendicitis (Group 2), and complicated appendicitis (Group 3). We calculated the sensitivity, specificity, positive and negative predictive values, the likelihood ratios in the diagnosis of appendicitis for white blood cell (WBC), neutrophil count, c-reactive protein (CRP), MPV, and PDW values were calculated. Results There were no significant differences in the MPV between Group 1 (n = 39; 7.89 ± 1.32 fL), Group 2 (n = 119; 7.80 ± 1.19 fL), and Group 3 (n = 89; 7.70 ± 0.80 fL; p = 0.141). Also, we found no significant differences in PDW between Group 1 (117.38% ± 1.17), Group 2 (17.17% ± 1.04), and Group 3 (17.12% ± 0.64; p = 0.228). Conclusions Only nine of the 208 patients whose pathology reports confirmed appendicitis had healthy values for both CRP and WBC. Many factors affect MPV and PDW. Therefore, platelet indices are not useful markers in diagnosing acute appendicitis.

Abstract
Platelet indices (PI) -- plateletcrit, mean platelet volume (MPV) and platelet distribution width (PDW) -- are a group of derived platelet parameters obtained as a part of the automatic complete blood count. Emerging evidence suggests that PIs may have diagnostic and prognostic value in certain diseases. This study aimed to summarize the current scientific knowledge on the potential role of PIs as a diagnostic and prognostic marker in patients having emergency, non-traumatic abdominal surgery. In December 2015, we searched Medline/PubMed, Scopus and Google Scholar to identify all articles on PIs. Overall, considerable evidence suggests that PIs are altered with acute appendicitis. Although the role of PI in the differential diagnosis of acute abdomen remains uncertain, low MPV might be useful in acute appendicitis and acute mesenteric ischemia, with high MPV predicting poor prognosis in acute mesenteric ischemia. The current lack of consistency and technical standards in studies involving PIs should be regarded as a serious limitation to comparing these studies. Further large, multicentre prospective studies concurrently collecting data from different ethnicities and genders are needed before they can be used in routine clinical practice.

Abstract
Objectives Acute appendicitis (AA) is the most common indication for emergency abdominal surgery, although it remains difficult to diagnose. In this study, we investigated the the clinical utility of mean platelet volume in the diagnosis of acute appendicitis. Methods The medical records of 241 patients who had undergone appendectomy between June 2013 and March 2014 were investigated retrospectively. Sixty patients who had undergone at least one complete blood count during preoperative hospital admission and who had no other active inflammatory conditions at the time the sample was taken were included in the study. Mean platelet volume and leukocyte count values were determined in each patient at hospital admission and during active acute appendicitis. Age, sex, mean platelet volume and leukocyte counts were recorded for each patient. Results The mean age of patients was 33.15±10.94 years and the male to female ratio was 1.5:1. The mean leukocyte count prior to acute appendicitis was 7.42±2.12×103/mm3. Mean leukocyte count was significantly higher (13.14±2.99×103/mm3) in acute appendicitis. The optimal leukocyte count cutoff point for the diagnosis of acute appendicitis was 10.10×103/mm3, with sensitivity of 94% and a specificity of 75%. The mean platelet volume prior to acute appendicitis was 7.58±1.11 fL. Mean platelet volume was significantly lower (7.03±0.8 fL) in acute appendicitis. The optimal mean platelet volume cutoff point for the diagnosis of AA was 6.10 fL, with a sensitivity of 83% and a specificity of 42%. Area under the curve for leukocyte count diagnosis was 0.67 and 0.69 for the diagnosis of AA by mean platelet volume. Conclusions Mean platelet volume was significantly decreased in acute appendicitis. Mean platelet volume can be used as a supportive diagnostic parameter in the diagnosis of acute appendicitis.

[PMID: 26688600 PMCID: PMC4673334 DOI: 10.1155/2015/542013] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/10/2015] [Revised: 10/16/2015] [Accepted: 10/28/2015] [Indexed: 02/07/2023]
Abstract
Introduction. Acute gangrenous appendicitis (AGA) is a common medical condition; however, the grade of appendicitis usually cannot be established preoperatively. We have attempted to identify some indicators, such as the mean platelet volume (MPV) and the platelet distribution width (PDW), to diagnose AGA. Aims. To evaluate whether or not the MPV and PDW are suitable markers to diagnose AGA. Methods. A retrospective study of 160 patients with AGA and 160 healthy patients was undertaken. Disease diagnosis was confirmed based on the pathologic examination of surgical specimens. Patient white blood cell (WBC) count, neutrophil ratio (NR), platelet (PLT) count, MPV, PDW, and hematocrit (HCT) were analyzed. Receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of these indices in AGA. Results. There were no significant differences between the AGA and control groups in age and gender. Compared to the control group, the WBC count, NR, and PDW were significantly higher (P < 0.001, resp.) and the MPV and HCT were significantly lower (P < 0.001, resp.) in the AGA group. The diagnostic specificities of the WBC count, NR, PLT count, MPV, PDW, and HCT were 86.3%, 92.5%, 58.1%, 81.7%, 83.9%, and 66.3%, respectively. Therefore, the NR had the highest diagnostic specificity for the diagnosis of AGA. Conclusions. This is the first study to assess the MPV and PDW in patients with AGA. Our present study showed that the MPV is reduced and the PDW is increased in patients with AGA; the sensitivity of PDW was superior to the MPV. A decreased MPV value and an increased PDW could serve as two markers to diagnose AGA. The NR had the highest specificity for the diagnosis of AGA.

Abstract
BACKGROUND We examined the changes of mean platelet volume (MPV) and platelet distribution width (PDW) in subjects with appendicitis and whether MPV and PDW could be used to predict the development of complication due to appendicitis. METHODS The healthy control group, the cases of appendicitis with perforation, and the cases of appendicitis without perforation were compared with regard to MPV and PDW. We determined whether MPV and PDW were independent variables predictive of the development of complication in subjects with appendicitis. RESULTS This retrospective case-control study included a total of 362 patients (249 of which were male (68.8 %) and 113 were female (31.2 %); median age, 30 [range, 18-84 years]). One hundred and ninety-two subjects (53 %) presented with appendicitis and 170 (47 %) comprised the healthy control group. Sixty-six (18.2 %) of the subjects with appendicitis developed complication. MPVs were lower in subjects of appendicitis without complication compared to the subjects of appendicitis with complication and the control group (MPV, 9.78 ± 0.99 vs. 10.20 ± 1.21 and 10.14 ± 1.03, respectively [p = 0.005]). The PDW levels were not different between the three groups. Independent variables predictive of the presence of complication included increased MPV and time from onset of symptoms to hospital presentation (odds ratio[confidence interval], p-value: 1.507[1.064-2.133], 0.021 and 18.887[5.139-69.410], 0.0001, respectively). CONCLUSIONS Our findings suggested these, MPV values in cases of appendicitis without complication were lower than the cases with complication and healthy control and MPV is a predictor of the development of complication in subjects with appendicitis.

[PMID: 25684947 PMCID: PMC4323458 DOI: 10.3748/wjg.v21.i6.1821] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2014] [Revised: 08/24/2014] [Accepted: 10/15/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate the diagnostic accuracy of the mean platelet volume and platelet distribution width in acute appendicitis.
METHODS: This retrospective, case-controlled study compared 295 patients with acute appendicitis (Group I), 100 patients with other intra-abdominal infections (Group II), and 100 healthy individuals (Group III) between January 2012 and January 2013. The age, gender, and white blood cell count, neutrophil percentage, mean platelet volume, and platelet distribution width values from blood samples were compared among the groups. Statistical analyses were performed using SPSS for Windows 21.0 software. In addition, the sensitivity, specificity, positive and negative predictive values and likelihood ratios, and diagnostic accuracy were calculated.
RESULTS: The mean ages of patients were 29.9 ± 12.0 years for Group I, 31.5 ± 14.0 years for Group II, and 30.4 ± 13.0 years for Group III. Demographic features such as age and gender were not significantly different among the groups. White blood cell count, neutrophil percentage and platelet distribution width were significantly higher in Group I compared to groups II and III (P < 0.05). Diagnostically, the sensitivity, specificity and diagnostic accuracy were 73.1%, 94.0%, and 78% for white blood cell count, 70.0%, 96.0%, and 76.0% for neutrophil percentage, 29.5%, 49.0%, and 34.0% for mean platelet volume, and 97.1%, 93.0%, and 96.0% for platelet distribution width, respectively. The highest diagnostic accuracy detected was for platelet distribution width between Group I and Group III (P < 0.01).
CONCLUSION: Platelet distribution width analysis can be used for diagnosis of acute appendicitis without requiring additional tests, thus reducing the cost and loss of time.

Abstract
BACKGROUND Diagnosis of acute appendicitis remains to be challenging with up to 30% negative exploration rates. In addition to careful clinical history and physical examination, we still need easily applicable, cheap and effective biomarker. PATIENTS AND METHODS A retrospective case-controlled study was designed in two groups, both containing 100 patients, acute appendicitis and control. Leukocyte count, neutrophil percentage, platelet count and meal platelet volume (MPV) were compared. RESULTS MPV values for acute appendicitis and control groups were 7.4 ± 0.9 fL (5.6-10.6) and 9.1 ± 1.6 fL (5.1-13.1). For the diagnosis of acute appendicitis, ROC analysis revealed 74% sensitivity and 75% specificity for a cut-off value of 7.95 fL of MPV, however, the diagnostic value of leukocyte count and/or neutrophil ratio was superior. CONCLUSION Our results suggest that, MPV value is an important parameter in the diagnosis of acute appendicitis, but in terms of sensitivity and specificity, leukocyte count and/or neutrophil percentage is superior.

IRANIAN RED CRESCENT MEDICAL JOURNAL 2013; 15:e11934. [PMID: 24693387 PMCID: PMC3955502 DOI: 10.5812/ircmj.11934] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/07/2013] [Revised: 09/27/2013] [Accepted: 10/21/2013] [Indexed: 12/29/2022]
Abstract
Background: The level of platelet volume (MPV) has been reported to be a laboratory marker in inflammatory cases. Objectives: The aim of this study was to seek whether MPV has a role in the diagnosis of acute appendicitis. It was also aimed to show the relationship of MPV with leukocyte count and C-reactive protein (CRP) level. Materials and Methods: This study was conducted via retrospective assessment of the hospital records of the adult patients who were operated for acute appendicitis between January 2010 and December 2012 and had a pathology report that confirmed the diagnosis of acute appendicitis. The patients in the control group were selected from healthy adults of similar age who applied to check-up clinic. The number of essential cases was defined by performing power analysis. Age, gender, leukocyte count, CRP, and MPV values were recorded. This study is a case controlled retrospective clinical study. Results: A total of 503 patients in the acute appendicitis group and 121 patients in the control group were included, making up a total of 624 subjects. The median MPV levels were 7.92 ± 1.68 fL in the acute appendicitis group, while 7.43 ± 1.34 fL in the control group. CRP, leukocyte count, and MPV level were significantly higher in the acute appendicitis group (P < 0.001). MPV, leukocyte count, and CRP had a sensitivity and specificity of 66% and 51%; 91% and 74%; and 97% and 41%, respectively. No correlation was found between MPV, CRP, and leukocyte count. Conclusions: MPV level was higher in patients with acute appendicitis. MPV may guide the diagnostic process of acute appendicitis. However, we detected that the sensitivity and specificity of leukocyte count and CRP were superior to those of MPV in the diagnosis of acute appendicitis.
