Abstract [en]

PURPOSE: The pathogenesis of appendicitis is not well understood. Environmental factors are regarded most important, but epidemiologic findings suggest a role of inflammatory and genetic mechanisms. This study determines the association of single nucleotide polymorphisms (SNPs) of inflammatory genes with appendicitis.

METHODS: As part of a larger prospective study on the diagnostic value of inflammatory variables in appendicitis, the genotype frequency of 28 polymorphisms in 26 inflammatory response genes from the appendicitis and control patients was analyzed in blood samples from 343 patients, 100 with appendicitis, and 243 with non-specific abdominal pain, using TaqMan SNP genotyping assays.

RESULTS: Associations with appendicitis were found for SNPs IL-13 rs1800925 with odds ratio (OR) 6.02 (95% CI 1.52-23.78) for T/T versus C/C + T/T, for IL-17 rs2275913 with OR 2.38 (CI 1.24-4.57) for A/A vs G/G + GA, for CCL22 rs223888 with OR 0.12 (0.02-0.90), and for A/A vs G/G + GA. Signs of effect modification of age for the association with appendicitis were found for IL-13 rs1800925 and CTLA4 rs3087243. Stratified analysis showed difference in association with severity of disease for IL-17 rs2275913 and CD44 rs187115.

CONCLUSIONS: The association of gene variants on risk of appendicitis and its severity suggest an etiologic role of genetically regulated inflammatory response. This may have implications for understanding the prognosis of untreated appendicitis as a possible self-limiting disorder and for understanding the inverse association of appendicitis with ulcerative colitis.

Abstract [en]

BACKGROUND: Interleukin 2 (IL2) is a significant factor activating T-cell-mediated immune response by stimulation of natural killer cells, T-cells and in development of regulatory T (Treg) cells. Recent studies have that IL2 participates in cancer development by modifying the local immune response. Based on the suggested role of the single nucleotide polymorphisms (SNPs) rs2069762, rs6822844 and rs11938795 of IL2 in the pathogenesis of certain diseases, the relationship of these SNPs with clinicopathological variables and their possible implication for prognosis and disease outcome were evaluated in a cohort of Swedish patients with colorectal cancer (CRC).

MATERIALS AND METHODS: TaqMan SNP genotype assays based on polymerase chain reaction were used for analysis of the IL2 SNPs in 467 patients with CRC and 467 healthy controls. Expression analysis of IL2 in plasma and CRC tissue was also performed.

RESULTS: The allelic variants T in rs11938795 and G in rs6822844 were significantly associated with a higher risk of CRC. Kaplan-Meier analysis showed that cancer-specific survival was worse for individuals with C allele for rs2069762 with stage II CRC and with T allele for rs6822844 with stage III CRC.

CONCLUSION: SNPs rs2069762, rs6822844 and rs11938795 of the IL2 gene may be helpful as prognostic biomarkers in the follow-up and management of the patients.

Abstract [en]

Platelet-derived growth factor D (PDGF-D) has been shown to mediate cellular processes of importance in cancer progression. This study aimed to investigate the expression and putative involvement of PDGF-D signaling in colorectal carcinogenesis. PDGF-D was expressed in vascular endothelial cells in tumor and normal tissues. PDGF-D stimulation of cells altered genes of importance in carcinogenic processes. In addition, PDGF-D increased the proliferation rate while imatinib inhibited these effects. PDGF-D and its PDGF receptor beta (PDGFR-β) are expressed in colorectal cancer and blockage of PDGF-D/PDGFR-β signaling using tyrosine kinase inhibitors, such as imatinib, might be important in inhibiting tumor-promoting actions.

Abstract [en]

BACKGROUND: Interleukin 4 (IL-4) and interleukin 13 (IL-13) are anti-inflammatory and immunomodulatory cytokines which share a common cellular receptor IL4Rα and are involved in the same signaling pathways. Our purpose was to assess whether genetic variants within IL-4, IL-13 and IL-4Rα are associated with the risk or clinical outcome of colorectal cancer (CRC).

METHODS: Three single nucleotide polymorphisms (SNPs) were screened in 466 patients with CRC and 445 healthy controls. The selected SNPs were IL-4 SNP rs2243250, IL-4Rα SNP rs1801275 and IL-13 SNP rs1800925.

RESULTS: We found that the genotype variant T/T in IL-13 gene was associated with a higher risk of CRC. Kaplan-Meier analysis showed that the cancer specific survival differed between C/C and CT + TT for IL-4 SNP. Moreover, the carriers of the T allele were associated with the highest risk of CRC death with a hazard ratio (HR) of 1.57, 95% CI 1.06-2.36, p = .024. The observed effect of the T allele was restricted to stage III patients.

CONCLUSION: Our results indicate IL-13 SNP rs1800925 as a risk factor for CRC and that IL-4 SNP rs2243250 could be a useful prognostic marker in the follow-up and clinical management of patients with CRC especially in stage III disease.

Abstract [en]

Background: Interleukin 32 (IL32) is an intracellular pluripotent cytokine produced by epithelial cells, monocytes, T-lymphocytes and natural killer cells and seems to be involved in the pathogenesis of cancer and inflammatory diseases. Our purpose was to assess the role of protein expression and genetic polymorphisms of IL32 in colorectal cancer (CRC) susceptibility.

Materials and Methods: To gain insight into clinical significance of IL32 in Swedish patients with CRC, using enzyme-linked immunosorbent assay, we determined whether IL32 protein level is altered in CRC tissue (n=75) compared with paired normal tissue and in plasma from patients with CRC (n=94) compared with controls (n=81). The expression of IL32 protein was confirmed by immunohistochemistry (n=73). We used Luminex technology to investigate protein levels of the cytokines IL6, tumor necrosis factor-a (TNFa) and vascular endothelial growth factor (VEGF) to relate these to IL32 levels in CRC tissue. Three single nucleotide polymorphisms (SNPs) (rs28372698, rs12934561, rs4786370) of the IL32 gene have been proposed as modifiers for different diseases. The present study evaluated the susceptibility of patients possessing these SNPs to CRC. Using TaqMan SNP genotyping assays, these SNPs were screened in Swedish patients with CRC (n=465) and healthy controls (n=331).

Results: We found no significant differences in the genotypic frequencies between the patients and healthy controls and no relation to survival for any of the SNPs. However, the SNP rs12934561 was statisticalLY significant associated with older patients. IL32 protein was up-regulated in CRC tissue and related to IL6, TNFa, and VEGF, and seems to be modulated by SNP rs28372698. The IL32 protein level in CRC tissue also reflects both disseminated disease and location. Conclusion. Our results suggest that altered IL32 protein concentrations in CRC tissue and genotypic variants of IL32 are related to disseminated CRC.

Abstract [en]

AIM: To investigate association of circulating inflammatory factors at the time of colorectal cancer (CRC) surgery with survival.

METHODS: Plasma levels from 174 CRC patients (69 females and 105 men), with median age 70 years (range 29-90), localized in the colon (n = 105) or rectum (n = 69), with stage I (n = 24), stage II (n = 54), stage III (n = 67) and stage IV (n = 29) were measured using commercially available Bio-Plex Pro™ Human Chemokine Panel 40-Plex, including 40 different chemokines, cytokines and interleukins. The prognostic association of each inflammatory factor was analysed as CRC-specific and total mortality.

RESULTS: Out of 174 patients, 66 died during the follow-up, 40 because of CRC specific mortality. High tertile levels of 8 factors were significantly associated with increased CRC-specific mortality, of which CCL1, CCL20, CCL24, CX3CL1, IL-4 and TNF-α remained significant in a multivariate Cox regression analysis. High tertile levels of 14 factors were associated with increased total mortality, of which CCL1, CCL15, CCL20, CX3CL1, CXCL13, IFN-γ, IL-2, IL-4 and IL-10 remained significant after adjustment for clinical covariates. For most of the inflammatory factors the association between higher tertile levels and an increased mortality in general appeared two years after surgery. High tertile levels of TNF-α and CCL24 were exclusively associated with CRC-specific mortality. The distribution of these factors were not associated with TNM stage with exception for CCL20.

CONCLUSION: High plasma levels of inflammatory factors are associated with increased risk of mortality among CRC patients and could be potential biomarkers for revealing prognosis.

Abstract [en]

Aim: The goal of the present study was to determine the prevalence and distribution of high-risk human papilloma virus (HPV) genotypes in women from two districts in and around Da Nang city, Vietnam.

Materials and Methods: All participants were randomly selected, 200 from the Hai Chau district and 200 from the Son Tra district. The detection and genotyping of HPV were performed by real-time polymerase chain reaction (PCR) technique.

Results: Out of a total of 400 women, we found that 38 (9.5%) were infected with a high-risk HPV genotype, the most prevalent genotypes being 16, 18, 58 and 59. By assessment of the HPV findings in relation to sociodemographic characteristics, we found significant differences between the two study districts and between the age groups, as well as differences associated with occupation and the use of contraceptives.

Conclusion: The proportion of high–risk genotypes other than 16 and 18 was relatively high, and since the HPV genotype distribution is known to vary greatly across populations, the information from this study can be used for planning of screening and vaccination programs in Da Nang.

Abstract [en]

Introduction: Abdominal aortic aneurysm (AAA) is a complex and deadly vascular disorder. The pathogenesis of AAA includes destruction and phenotypic alterations of the vascular smooth muscle cells (VSMCs) and aortic tissues. PPARγ coactivator-1 alpha (PGC1α) regulates VSMC migration and matrix formation and is a major inducer of mitochondrial biogenesis and function, including oxidative metabolism. Methods: Protein and gene expression of PGC1α and markers for mitochondria biogenesis and cell type-specificity were analysed in AAA aortas from humans and mice and compared against control aortas. Results: Gene expression of PPARGC1A was decreased in human AAA and angiotensin (Ang) II-induced AAA in mice when compared to control vessels. However, high expression of PGC1α was detected in regions of neovascularisation in the adventitia layer. In contrast, the intima/media layer of AAA vessel exhibited defective mitochondrial biogenesis as indicated by low expression of PPARGC1A, VDAC, ATP synthase and citrate synthase. Conclusion: Our results suggest that mitochondrial biogenesis is impaired in AAA in synthetic SMCs in the media, with the exception of newly formed supporting vessels in the adventitia where the mitochondrial markers seem to be intact. To our knowledge, this is the first study investigating PGC1α and mitochondria biogenesis in AAA.

Abstract [en]

The DNA repair genes XRCC1 and XRCC6 have been proposed to participate in the pathological process of cancer by modulating the DNA repair capacity. This study evaluated the susceptibility of the single-nucleotide polymorphisms (SNPs) XRCC1 (rs25487, G > A) and XRCC6 (rs2267437, C > G) to colorectal cancer (CRC) and their association with clinical parameters in Swedish patients with CRC. Using the TaqMan system, these SNPs were screened in 452 patients and 464 controls. No significant difference in genotype distribution was found between the patients and controls, or any significant association with cancer-specific or disease-free survival in patients. However, we showed that the carriers of allele A in XRCC1 (rs25487, G > A) were connected with a higher risk of disseminated CRC (Odds Ratio = 1.64; 95% Confidence Interval = 1.12–2.41, p = 0.012).

Abstract [en]

We surveyed the prevalence of Dientamoeba fragilis, Giardia duodenalis, Entamoeba histolytica, Entamoeba dispar, and Cryptosporidium spp in individuals with and without gastrointestinal (GI) symptoms residing in and around Da Nang city, Vietnam. Fecal samples were collected from children (n = 100) and adults (n = 80) with GI symptoms and from healthy individuals (n = 88) reporting no GI symptoms. Parasite detection was performed by multiplex real-time PCR. Overall, except for G. duodenalis, we found a low prevalence (<5%) of D. fragilis and E. dispar and no detection of E. histolytica and C. spp in all participants with GI symptoms. Specifically for D. fragilis this contrasts with findings in European populations of children with GI symptoms showing prevalence up to 73%. Moreover, our results indicate that the prevalence of G. duodenalis is higher in patients with GI symptoms compared to asymptomatic individuals and this difference is most obvious in young patients.
