These findings have demonstrated that HpSA as a relatively simple, inexpensive and time saving noninvasive test is a reliable method for detection of H.pylori infections in children.
Background: Food protein-induced allergic proctocolitis (FPIAP) is mostly a non-immunoglobulin E-mediated disease where a T-cell-mediated reaction to cow's milk protein has been suggested. We determined the expression of transforming growth factor (TGF)-β, TGF-β receptor-1, tumor necrosis factor (TNF)-α, CD86, and CD23 on the colon mucosa to investigate their roles in the pathogenesis of the two subtypes of FPIAP, i.e. infantile FPIAP and FPIAP in older children. Methods: Group 1 comprised children with infantile FPIAP (age <6 months, n = 21), group 2 referred to FPIAP in older children (age >1.5 years, n = 7), and group 3 included children with juvenile hyperplastic polyps (n = 22). Immunohistochemical staining of colonic biopsy specimens was performed. Results: The expression of TNF-α was significantly higher in groups 1 and 2 compared to group 3. Group 2 patients had a significantly lower TGF-β expression compared to the other groups. The expression of CD86 was higher in group 1 than in group 3 (p = 0.012). Eosinophil counts per high-power field in the lamina propria were significantly correlated with CD86 expression (p = 0.026, r = 0.388). Conclusion: Our results suggest that TNF-α is implicated in the pathogenesis of both types of FPIAP. The decreased activity of TGF-β receptor-1 accompanied by the increased expression of CD86 in infants and the decreased activity of TGF-β in older children appear to play a role in the development of FPIAP.
Expression of the studied precancerous markers in significant amounts indicates the importance of childhood H. pylori infection in the constitution of gastric cancer in adulthood.
Objective: To investigate serum levels of CA 19.9, CA 125 and carcinoembryonic antigen (CEA) in patients with different stages of chronic obstructive pulmonary disease (COPD). Patients and Methods: Fifty-three consecutive patients (50 males, 3 females, mean age 67.6 ± 10.1 years) with COPD were included in this study. Serum levels of CA 19.9, CA 25 and CEA were determined by the chemiluminescent immunometric method. Based on values obtained from pulmonary function tests, the patients were divided into 3 groups: moderate (21), severe (18) and very severe (14). Data were analyzed with a Kruskal-Wallis one-way analysis of variance test and Mann-Whitney U test. Results: The mean serum levels of CA 125 and CA 19.9 were significantly higher in patients with very severe COPD (p = 0.013 and p = 0.017, respectively) than in patients with severe and moderate COPD (p < 0.05). Patients with cor pulmonale had significantly high mean serum levels of CEA, CA 19.9 and CA 125 (p < 0.05). Patients using a long-acting β-agonist and theophylline showed significantly higher mean serum levels of CA 125 than patients who were not (p < 0.05). Conclusion: Data showed that the increased serum tumor markers in patients with COPD might be due to the severity of COPD, medication and cor pulmonale.
AIM:To evaluate serum neopterin levels and their correlations with liver function tests and histological grade in children with hepatitis-B-related chronic liver disease. METHODS: The study population comprised 48 patients with chronic active hepatitis B, 32 patients with hepatitis-B-related active liver cirrhosis and 40 normal controls. Serum neopterin was measured using an enzyme-linked immunosorbent assay. RESULTS: The mean ± SD serum neopterin levels were 14.2 ± 5.6 nmol/L in patients with chronic hepatitis, 20.3 ± 7.9 nmol/L in patients with liver cirrhosis and 5.2 ± 1.4 nmol/L in control group. Serum neopterin levels were significantly higher in patients with chronic hepatitis (P = 0.005) and cirrhosis patients (P = 0.008), than in control subjects. Cirrhotic patients had significantly higher serum neopterin levels than patients with chronic hepatitis (P = 0.004). There was a positive correlation between serum neopterin levels and alanine aminotransferase levels in patients with chronic hepatitis (r = 0.41, P = 0.004) and cirrhotic patients (r = 0.39, P = 0.005). Positive correlations were detected between serum neopterin levels and inflammatory score in patients with chronic hepatitis (r = 0.51, P = 0.003) and cirrhotic patients (r = 0.49, P = 0.001).
CONCLUSION:Our results suggest that serum neopterin levels can be considered as a marker of inflammatory activity and severity of disease in children with hepatitis-B-related chronic liver disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
