Abstract

Serum 25(OH)D deficiency consistently demonstrated molecular mechanisms through which chronic inflammation is associated with the risk of nasopharyngeal carcinoma (NPC). This study aimed to determine the association between serum 25(OH)D and NPC. A matched case–control study was conducted at two local hospitals. A total of 300 histologically confirmed NPC cases were matched with controls for age, gender, and ethnicity, and assessed for vitamin D status and other nutritional factors. Mean Vitamin D concentration was significantly lower among cases compared to controls (63.17 ± 19.15 nmol/L and 67.34 ± 23.06 nmol/L) (t = −2.41, p = 0.016). Multiple conditional logistic regression analysis indicated that higher levels of serum 25(OH)D were associated with reduced odds of NPC (AOR = 0.73, 95 CI = 0.57–0.94, p = 0.016) controlling for confounders including BMI, physical activity, smoking status, alcohol consumption, consumption of food high in vitamin D, salted fish consumption, and family history of NPC. There was a significant association between inadequate serum 25(OH)D status with accumulation of four risk factors and increased odds of getting NPC using polynomial regression analysis. Increased NPC odds ratios were observed after sequential accumulation of additional risk factors with the presence of inadequate serum 25(OH)D status (OR = 0.54, 95 CI = 0.27, 4.77, p = 0.322, OR = 1.04, 95 CI = 0.64, 1.72, p = 0.267, OR = 1.15, 95 CI = 0.73, 1.80, p = 0.067, OR = 1.93, 95 CI = 1.13, 3.31, p = 0.022, and OR = 5.55, 95 CI = 1.67, 10.3, p < 0.001 respectively). Future research in Malaysia should involve both prospective cohort studies and randomized controlled trials to confirm and further clarify the role of vitamin D in NPC outcomes.

Abstract

introductionTargeted capture of genomic regions of interest for massively parallel sequencing allows simultaneous screening of mutations in hundreds of loci in genetically heterogeneous human diseases. It has become a widely used method in genetic testing because it leads to increased cost-effectiveness, shorter turn-around-time, higher accuracy and accessibility. Nasopharyngeal Carcinoma (NPC) is uncommon in many parts of the world with the age-standardize rates of about 2.2 per 100,0003 but is one of the most prevalent cancers in Southeast Asia especially among the Bidayuhs and Kadazans, with its aetiology understudied. Familial clustering shows that individuals with first degree family history of NPC have elevated risk of NPC with odd ratios ranged from 2 to 20 as compared to those with no family history of NPC. As genetic factors such as tumor suppressor genes that confers susceptibility to NPC remain unclear and understudied in different ethnic groups in Malaysia, we conduct Whole Exome Sequencing and Targeted Sequencing in 24 NPC cases with family history of NPC to evaluate the feasibility of targeted sequencing as well as to identify genetic factors that may lead to development of NPC. Methodology[Refer to Poster]. Results[Refer to Poster]. Discussion and ConclusionGenetic susceptibility to cancer is usually caused by dominantly inherited heterozygous mutations of tumour suppressor genes. However, tumour suppressor genes which confer such increased risk of NPC are understudied among various high risk groups in Malaysia. Comprehensive analysis were performed to identify potential susceptibility genes and in-depth characterization and validation of the target genes should be done to evaluate the association of such genes in pathogenesis of NPC. In our study, the targeted sequencing data demonstrates very high correlation with the WES data and our results show that both platforms are useful for the identification of potential tumour suppressor genes in NPC. It is found that in NPC, pathways related to innate immune system and DNA repair are affected. This will further enhance our understanding in the molecular basis of the disease and shed light for future prevention, diagnosis, gene therapy and/or management of NPC.

Abstract

Reported COVID-19 deaths in Germany are relatively low as compared to many European countries. Among the several explanations proposed, an early and large testing of the population was put forward. Most current debates on COVID-19 focus on the differences among countries, but little attention has been given to regional differences and diet. The low-death rate European countries (e.g. Austria, Baltic States, Czech Republic, Finland, Norway, Poland, Slovakia) have used different quarantine and/or confinement times and methods and none have performed as many early tests as Germany. Among other factors that may be significant are the dietary habits. It seems that some foods largely used in these countries may reduce angiotensin-converting enzyme activity or are anti-oxidants. Among the many possible areas of research, it might be important to understand diet and angiotensin-converting enzyme-2 (ACE2) levels in populations with different COVID-19 death rates since dietary interventions may be of great benefit.

Abstract

Background The number of available reports regarding the influence of ethnicity on clinical features of allergic rhinitis (AR), especially disease severity in tropical climates, is limited. We aimed to compare clinical parameters and disease severity in AR patients of different ethnicities. Methods Malay, Chinese, and Indian AR patients (n = 138) with confirmed sensitivity to Dermatophagoides pteronyssinus, Dematophagoides farinae, and Blomia tropicalis were tested for mite-specific immunoglobulin E (sIgE) levels. A detailed questionnaire was used to collect data on nasal symptom score (NSS), ocular symptom score (OSS), sum of symptoms score (SSS), quality of life score (QLS), symptomatic control score (SCS), and total sum of scores (TSS) and correlate the derived data with patients’ demography, mite-polysensitivity, and sIgE levels. Results AR-related symptoms were most severe in Malays and least in Chinese (p < 0.01). Age (r = 0.516 to 0.673, p < 0.05) and duration of AR (r = 0.635 to 0.726, p < 0.01) correlated positively with severity domains (NSS, SSS, QLS, and TSS) in Chinese. Duration of concurrent allergies was highest in Malays (p < 0.05). Polysensitivity predicted increased sIgE levels in Malays (r = 0.464 to 0.551, p < 0.01) and Indians (r = 0.541 to 0.645, p < 0.05) but affected NSS, SSS, and TSS only in Indians (r = 0.216 to 0.376, p < 0.05). sIgE levels were lowest among Chinese but correlated strongly with NSS, OSS, SSS, and TSS (r = 0408 to 0.898, p < 0.05). Conclusion Clinical parameters in AR may be influenced by race. Symptoms were most severe among Malays but did not correlate with other variables examined. Although Indian ethnicity did not impact disease severity, duration of concurrent allergies and mite-polysensitivity was associated with more severe disease. Age, duration of disease, and sIgE levels may be useful indicators of disease severity in Chinese.

Abstract

Nasopharyngeal carcinoma (NPC) is originated from the epithelial cells of nasopharynx, Epstein–Barr virus (EBV)‐associated and has the highest incidence and mortality rates in Southeast Asia. Late presentation is a common issue and early detection could be the key to reduce the disease burden. Sensitivity of plasma EBV DNA, an established NPC biomarker, for Stage I NPC is controversial. Most newly reported NPC biomarkers have neither been externally validated nor compared to the established ones. This causes difficulty in planning for cost‐effective early detection strategies. Our study systematically evaluated six established and four new biomarkers in NPC cases, population controls and hospital controls. We showed that BamHI‐W 76 bp remains the most sensitive plasma biomarker, with 96.7% (29/30), 96.7% (58/60) and 97.4% (226/232) sensitivity to detect Stage I, early stage and all NPC, respectively. Its specificity was 94.2% (113/120) against population controls and 90.4% (113/125) against hospital controls. Diagnostic accuracy of BamHI‐W 121 bp and ebv‐miR‐BART7‐3p were validated. Hsa‐miR‐29a‐3p and hsa‐miR‐103a‐3p were not, possibly due to lower number of advanced stage NPC cases included in this subset. Decision tree modeling suggested that combination of BamHI‐W 76 bp and VCA IgA or EA IgG may increase the specificity or sensitivity to detect NPC. EBNA1 99 bp could identify NPC patients with poor prognosis in early and advanced stage NPC. Our findings provided evidence for improvement in NPC screening strategies, covering considerations of opportunistic screening, combining biomarkers to increase sensitivity or specificity and testing biomarkers from single sampled specimen to avoid logistic problems of resampling. What's new? Plasma Epstein–Barr virus (EBV) DNA is an established nasopharyngeal carcinoma (NPC) biomarker, but not all cases are associated with EBV and its sensitivity for stage I NPC remains controversial. Meanwhile, most newly‐reported NPC biomarkers have neither been externally validated nor compared to established biomarkers. This study systematically evaluates six established and four new biomarkers in NPC cases, population controls, and hospital controls. The findings provide evidence to policymakers for improvement in NPC screening and monitoring strategies, covering considerations of opportunistic screening, combining biomarkers to increase sensitivity/specificity, and testing multiple biomarkers on single specimens to avoid the logistic problems of resampling.

The number of available reports regarding the influence of ethnicity on clinical features of allergic rhinitis (AR), especially disease severity in tropical climates, is limited. We aimed to compare clinical parameters and disease severity in AR patients of different ethnicities.Malay, Chinese, and Indian AR patients (n = 138) with confirmed sensitivity to Dermatophagoides pteronyssinus, Dematophagoides farinae, and Blomia tropicalis were tested for mite-specific immunoglobulin E (sIgE) levels. A detailed questionnaire was used to collect data on nasal symptom score (NSS), ocular symptom score (OSS), sum of symptoms score (SSS), quality of life score (QLS), symptomatic control score (SCS), and total sum of scores (TSS) and correlate the derived data with patients' demography, mite-polysensitivity, and sIgE levels.AR-related symptoms were most severe in Malays and least in Chinese (p0.01). Age (r = 0.516 to 0.673, p0.05) and duration of AR (r = 0.635 to 0.726, p0.01) correlated positively with severity domains (NSS, SSS, QLS, and TSS) in Chinese. Duration of concurrent allergies was highest in Malays (p0.05). Polysensitivity predicted increased sIgE levels in Malays (r = 0.464 to 0.551, p0.01) and Indians (r = 0.541 to 0.645, p0.05) but affected NSS, SSS, and TSS only in Indians (r = 0.216 to 0.376, p0.05). sIgE levels were lowest among Chinese but correlated strongly with NSS, OSS, SSS, and TSS (r = 0408 to 0.898, p0.05).Clinical parameters in AR may be influenced by race.

Abstract

Background: Nasopharyngeal carcinoma (NPC) is a neoplasm of the epithelial lining of the nasopharynx. Despite various reports linking genomic variants to NPC predisposition, very few reports were done on copy number variations (CNV). CNV is an inherent structural variation that has been found to be involved in cancer predisposition. Methods: A discovery cohort of Malaysian Chinese descent (NPC patients, n = 140; Healthy controls, n = 256) were genotyped using Illumina® HumanOmniExpress BeadChip. PennCNV and cnvPartition calling algorithms were applied for CNV calling. Taqman CNV assays and digital PCR were used to validate CNV calls and replicate candidate copy number variant region (CNVR) associations in a follow-up Malaysian Chinese (NPC cases, n = 465; and Healthy controls, n = 677) and Malay cohort (NPC cases, n = 114; Healthy controls, n = 124). Results: Six putative CNVRs overlapping GRM5, MICA/HCP5/HCG26, LILRB3/LILRA6, DPY19L2, RNase3/RNase2 and GOLPH3 genes were jointly identified by PennCNV and cnvPartition. CNVs overlapping GRM5 and MICA/HCP5/HCG26 were subjected to further validation by Taqman CNV assays and digital PCR. Combined analysis in Malaysian Chinese cohort revealed a strong association at CNVR on chromosome 11q14.3 (Pcombined = 1.54x10-5; odds ratio (OR) = 7.27; 95% CI = 2.96–17.88) overlapping GRM5 and a suggestive association at CNVR on chromosome 6p21.3 (Pcombined = 1.29x10-3; OR = 4.21; 95% CI = 1.75–10.11) overlapping MICA/HCP5/HCG26 genes. Conclusion: Our results demonstrated the association of CNVs towards NPC susceptibility, implicating a possible role of CNVs in NPC development.

Abstract

Background: DNA repair pathways play a crucial role in maintaining the human genome. Previous studiesassociated DNA repair gene polymorphisms (XPD Lys751Gln, XRCC1 Arg280His and XRCC1 Arg399Gln)with nasopharyngeal carcinoma. These non-synonymous polymorphisms may alter DNA repair capacity andthus increase or decrease susceptibility. The present study aimed to determine the genotype distribution of XPDcodon 751, XRCC1 codon 280 and codon 399 polymorphisms and haplotype associations among NPC cases andcontrols in the Malaysian population. Materials and Methods: We selected 157 NPC cases and 136 controls fromtwo hospitals in Kuala Lumpur, Malaysia for this study. The polymorphisms studied were genotyped by PCRRFLPassay and allele and genotype frequencies, haplotype and linkage disequilibrium were determined usingSNPstat software. Results: For the XPD Lys751Gln polymorphism, the frequency of the Lys allele was higher incases than in controls (94.5% versus 85.0%). For the XRCC1 Arg280His polymorphism, the frequency of Argallele was 90.0% and 89.0% in cases and controls, respectively and for XRCC1 Arg399Gln the frequency of theArg allele was 72.0% and 72.8% in cases and controls respectively. All three polymorphisms were in linkagedisequilibrium. The odds ratio from haplotype analysis for these three polymorphisms and their associationwith NPC was 1.93 (95%CI: 0.90-4.16) for haplotype CGC vs AGC allele combinations. The global haplotypteassociation with NPC gave a p-value of 0.054. Conclusions: Our study provides an estimate of allele and genotypefrequencies of XRCC1Arg280His, XRCC1 Arg399Gln and XPD Lys751Gln polymorphisms in the Malaysianpopulation and showed no association with nasopharyngeal cancer.

Abstract

Introduction: Nasopharyngeal Carcinoma (NPC) is the second most common cancer among men in Malaysia. Establishing local data will help to improve the treatment strategies and lower the anxiety and depression level among NPC patients. Our aim was to compare the level of symptoms of anxiety and depression and the coping strategies employed between NPC and cancer-free patients. Methods: A comparative cross-sectional study with universal sampling was conducted on 22 NPC patients and 30 cancer-free patients from the Oncology and Radiotherapy Department and Ear, Nose and Throat clinic of Hospital Kuala Lumpur (HKL) between 12 to 29 May 2008. In this study, the symptoms of depression and anxiety were obtained by using the Hospital Anxiety and Depression Scale (HADS) while Brief COPE questionnaire was used to understand patients’ coping strategies. Results: The prevalence of NPC was higher in the Chinese, men, aged between 40 and 59 years, and those from the lower income group. The levels of anxiety and depression symptoms were found to be higher in the NPC group as compared to the cancer-free group. However, only the level of depression was found significantly related to the NPC group (p=0.002). This study also found that the two comparison groups were using different types of coping strategies. The NPC patients mainly used ‘acceptance’ as their coping strategy while the comparative group most often used ‘religion’. Among the types of coping strategies reported by the patients, ‘use of instrumental support’ type was found to be associated with a lower level of anxiety (p = 0.035) and ‘humour’ type was associated with lower depressive symptoms (p = 0.269). On the contrary, ‘selfblame’ type was associated with both anxiety (p =0.0001) and depression (p = 0.001) symptoms. In addition, patients with different gender, ethnicity, educational levels, and monthly income were also found to have significant differences in their levels of anxiety and depression as well as type of cop

Abstract

Nasopharyngeal carcinoma (NPC) is an epithelial squamous cell carcinoma on the mucosal lining of the nasopharynx. The etiology of NPC remains elusive despite many reported studies. Most studies employ a single platform approach, neglecting the cumulative influence of both the genome and transcriptome toward NPC development. We aim to employ an integrated pathway approach to identify dysregulated pathways linked to NPC. Our approach combines imputation NPC GWAS data from a Malaysian cohort as well as published expression data GSE12452 from both NPC and non-NPC nasopharynx tissues. Pathway association for GWAS data was performed using MAGENTA while for expression data, GSA-SNP was used with gene p values derived from differential expression values from GEO2R. Our study identified NPC association in the gene ontology (GO) axonemal dynein complex pathway ( pGWAS-GSEA = 1.98 × 10−2; pExpr-GSEA = 1.27 × 10−24; pBonf-Combined = 4.15 × 10−21). This association was replicated in a separate cohort using gene expression data from NPC and non-NPC nasopharynx tissues ( pAmpliSeq-GSEA = 6.56 × 10−4). Loss of function in the axonemal dynein complex causes impaired cilia function, leading to poor mucociliary clearance and subsequently upper or lower respiratory tract infection, the former of which includes the nasopharynx. Our approach illustrates the potential use of integrated pathway analysis in detecting gene sets involved in the development of NPC in the Malaysian cohort. [ABSTRACT FROM AUTHOR]
