calca-protein--human and Abdominal-Pain

The objective of the study is to evaluate the usefulness of the leukocyte (white blood count [WBC]) and neutrophil (absolute neutrophil count [ANC]) counts; the values of C-reactive protein (CRP), procalcitonin, and calprotectin (CP); and the APPY1 Test panel of biomarkers, to identify children with abdominal pain at low risk for appendicitis.. Children 2 to 14 years of age with abdominal pain suggesting acute appendicitis (AA) were prospectively included. Procalcitonin, calprotectin, C-reactive protein, white blood count, ANC, and the new plasma APPY1 Test were performed. The final diagnosis was determined by histopathology in cases of AA and telephone follow-up in children discharged without AA.. Between February 2012 and June 2013, 185 children were enrolled with an average age of 9.32±2.7 years. Eighty-nine (48.1%) were finally diagnosed with AA. The APPY1 Test panel showed the highest discriminatory power, sensitivity of 97.8 (95% confidence interval [CI], 92.2-99.4), negative predictive value of 95.1 (95% CI, 83.9-98.7), negative likelihood ratio of 0.06 (95% CI, 0.01-0.22), and specificity of 40.6 (95% CI, 31.3-50.5). A negative APPY1 Test and ANC less than 7500 per milliliter provided a sensitivity of 100 (95% CI, 95.9-100), negative predictive value of 100 (95% CI, 89.8-100), and specificity of 35.4 (95% CI, 26.6-45.4). In the multivariate analysis, only the APPY1 Test and ANC greater than 7500 per milliliter were significant risk factors for AA (odds ratio, 13.76; 95% CI, 3.02-62.57, and odds ratio, 6.37; 95% CI, 2.89-14.28, respectively).. The APPY1 Test panel with ANC could be useful in identifying children with abdominal pain suggestive of AA who are at low risk for this disease.

Appendicitis clinical diagnosis in children is difficult and the acute inflammatory markers hyperleucocytis and CRP do not contribute to it.. To study the predictive value of procalcitonin (PCT) and to assess variations of its serum level according to inflammatory lesions in paediatric appendicitis.. Among 101 children aged two and 15, hospitalized for painful abdominal syndromes, 70 underwent operation for acute appendicitis and appendiceal peritonitis, 31 had no operation. PCT was evaluated in all children, normal serum concentration was <0,5 microg/L. Every appendicectomy part has been examined through histological analysis to confirm the diagnosis and the histological lesions have been classified into three categories according to their severity.. Out of 70 appendix analysed at histology, 68 (97%) were healthy and 2 (3%)were unhealthy. Among the 68 cases of healthy appendix, 19 had a PCT higher than 0,5 microg/L and among 33 cases of unhealthy appendix 4 had a PCT higher than 0,5 microg/L. The PCT mean of healthy children was not significantly different from unhealthy appendix population, appendicitis prevalence was 0,67, PCT sensitivity 28%: IC 95% [18-40], specificity 88%: IC 95% [72-97], positive predictive value 83%: IC 95% [61-95], and negative predictive value 37%: IC 95% [26-49]. PCT mean increases with the severity of inflammatory lesions of the appendix (P=0,0051).. PCT has not a good predictive value in acute paediatric appendicitis but remains a good indicator of severity in paediatric appendicitis.

This study aimed to evaluate the utility of C-reactive protein (CRP), procalcitonin (PCT), D-lactate, and white blood cell (WBC) count as an aid to distinguish appendicitis from other diagnoses.. This prospective, observational study was conducted at an urban tertiary academic pediatric emergency department (ED). Subjects aged 1 to 18 years presenting with abdominal pain suspicious for acute appendicitis were enrolled. Data included history, physical examination, laboratory data (complete blood count, CRP, D-lactate, PCT [semiquantitative]), laboratory results, x-rays, surgical consultation notes, histopathology, and admission data. Stepwise logistic regression analysis was performed to identify independent risk factors.. Two hundred nine subjects (59% male, 41% female) were enrolled over 6 months. One hundred fifteen subjects were histologically diagnosed with appendicitis; 94 subjects did not have appendicitis and were used as controls. Mean values of WBC, CRP, PCT, and absolute neutrophil count in subjects with definitive appendicitis were significantly higher than in subjects with no definitive appendicitis. D-Lactate levels were noncorrelative. Significant independent risk factors identified for definitive appendicitis included WBC count more than 12 cells × 1000/mm(3) (adjusted odds ratio [AOR], 6.54), CRP level greater than 3 mg/dL (AOR, 3.44), presence of hopping pain (AOR, 2.69), and presence of pain with walking (AOR, 2.56). Odds ratio for definitive appendicitis and its 95% confidence interval was found to be 7.75 for subjects with both WBC more than 12 cells × 1000/mm(3) and CRP greater than 3 mg/dL.. C-reactive protein with WBC is useful in distinguishing appendicitis from other diagnoses in pediatric subjects presenting to the ED. White blood cell count greater than >12 cells × 1000/mm(3) and CRP greater than 3 mg/dL increases the likelihood of appendicitis. D-Lactate is not a useful laboratory adjunct.

The current study was to determine the serum/plasma levels of VEGF, IL-6, malondialdehyde (MDA), nitric oxide (NO), PCT and CRP in gastric carcinoma and correlation with the stages of the disease and accompanying infection.. We examined the levels of serum VEGF, IL-6, PCT, CRP and plasma MDA, NO in 42 preoperative gastric cancer patients and 23 healthy subjects. There were infection anamneses that had no definite origin in 19 cancer patients.. The VEGF levels (mean+/-SD; pg/mL) were 478.05+/-178.29 and 473.85+/-131.24 in gastric cancer patients with and without infection, respectively, and these values were not significantly different (P>0.05). The levels of VEGF, CRP, PCT, IL-6, MDA and NO in cancer patients were significantly higher than those in healthy controls and the levels of CRP, PCT, IL-6, MDA and NO were statistically increased in infection group when compared with non-infection group (P<0.001).. Although serum VEGF concentrations were increased in gastric cancer, this increase might not be related to infection. CRP, PCT, IL-6, MDA and NO have obvious drawbacks in the diagnosis of infections in cancer patients. These markers may not help to identify infections in the primary evaluation of cancer patients and hence to avoid unnecessary antibiotic treatments as well as hospitalization. According to the results of this study, IL-6, MDA, NO and especially VEGF can be used as useful parameters to diagnose and grade gastric cancer.
