Abstract
Numerous studies have investigated the relationship between various candidate gene polymorphisms and gallbladder stone disease (GSD) across ethnic populations; however, the results are often inconsistent. This meta-analysis aims to comprehensively evaluate the influence of common ABCG8 T400K, ABCG8 D19H, ABCG8 C54Y, ApoB100 EcoRI, ApoB100 XbaI, ApoE HhaI, CETP TaqI, CYP7A1 Bsa, LRPAP1 I/D and TNF-α A308G polymorphisms on the risk of gallbladder stone disease. 33 Full-text articles with 9250 cases and 12,029 healthy controls (total 21,279 subjects) were analyzed using the RevMan software (V5.1) and the Comprehensive Meta-analysis software (Version 2.0, BIOSTAT, Englewood, NJ) a Random-effects model was applied. Begg's funnel plots, Fail-safe number, Egger's regression intercept and Begg and Mazumdar rank correlation tests were performed for the potential publication bias and sensitivity analysis. The studies were also sub-grouped into European and non-European groups to find out role of ethnicity, if any, on GSD risk. Studies included in quantitative synthesis were ABCG8 T400K rs4148217 (cases/controls, n = 671/1416) (4 studies), ABCG8 D19H rs11887534 (n = 1633/2306) (8 studies), ABCG8 C54Y rs4148211 (n = 445/1194) (3 studies), ApoB100 EcoRI rs1042031 (n = 503/390) (4 studies), ApoB100 XbaI rs693 (n = 1214/1389) (9 studies), ApoE HhaI rs429358 (n = 1335/1482) (12 studies), CETP TaqI rs708272 (n = 1038/1025) (5 studies), CYP7A1 Bsa rs3808607 (n = 565/514) (3 studies), LRPAP1 I/D rs11267919 (n = 849/900) (3 studies), TNF-α A308G rs1800629 (n = 997/1413) (3 studies). The combined results displayed significant association of ABCG8 D19H (GC + CC) [OR with 95%CI = 2.2(1.7-2.8); p < 0.00001], ABCG8 Y54C (GA + GG) [OR with 95%CI = 0.65(0.5-0.9); p = 0.01]. APOB100 EcoRI (GG vs. AA) [OR with 95%CI = 0.51(0.3-0.9); p = 0.05], (GG vs. GA) [OR with 95%CI = 0.6(0.4-0.9); p = 0.04], (GA + AA) [OR with 95%CI = 0.6(0.4-0.9); p = 0.006]. APOB Xba I (X- vs. X+) [OR with 95%CI = 0.53(0.3-0.8); p = 0.006. APOE Hha I (E4/E4 vs. E3/E3) [OR with 95%CI = 3.5(1.1-14.9); p = 0.04] and LRPAP1 I/D (ID + II) [OR with 95%CI = 1.27(1.0-1.6); p = 0.03] with the GSD risk. It was found that ABCG D19H was significantly associated with GSD in both European and Non-European populations. While APOB XbaI and LRPAP1 I/D markers were associated with gallstone disease only in Non- European population. Additionally, APOE HhaI and APOB 100 ECoRI were found to be associated with GSD only in European population. The results of quantitative synthesis suggest that the ABCG8 D19H polymorphism was associated with the increased risk of GSD in both European and Non-European populations, APOE Hha I and LRPAP1 I/D polymorphisms were associated with the increased risk of GSD in European and Non-European population respectively. However, no association was found in ABCG8 T400K, CETP Taq1, CYP7A1 Bsa and TNF-A308G polymorphisms with Gallstone Disease.

Abstract
BACKGROUND Susceptibility to lung cancer has been shown to be modulated by inheritance of polymorphic genes encoding cytochrome P450 1A1 (CYP1A1) and glutathione S transferases (GSTM1 and GSTT1), which are involved in the bioactivation and detoxification of environmental toxins. This might be a factor in the variation in lung cancer incidence with ethnicity. MATERIALS AND METHODS We conducted a case-control study of 218 northern Indian lung cancer patients along with 238 healthy controls, to assess any association between CYP1A1, GSTM1 and GSTT1 polymorphisms, either separately or in combination, with the likelihood of development of Lung cancer in our population. RESULTS We observed a significant difference in the GSTT1 null deletion frequency in this population when compared with other populations (OR=1.87, 95%CI: 1.25-2.80-0.73, P=0.002). However, GSTM1 null genotype was found associated with lung cancer in the non-smoking subgroup. (P=0.170). CONCLUSIONS Our study showed the GSTT1 null polymorphism to be associated with smoking-induced lung cancer and the GSTM1 null polymorphism to have a link with non-smoking related lung cancer.

Abstract
OBJECTIVE Cyclooxygenase-2 (COX-2) enzyme is a major mediator of inflammation in periodontitis, leading to loss of gingival tissues and alveolar bone supporting the teeth. Previous studies have explored the role of COX-2 polymorphisms with the risk of periodontitis in different ethnic groups; however, findings are inconsistent. So, we aimed to investigate the association of COX-2 polymorphisms (rs20417, rs689466, and rs5275) in susceptibility to chronic periodontitis (CP) in northern Indian population. Meta-analysis was also carried out to precisely estimate the effect of COX-2 polymorphisms in CP. MATERIALS AND METHODS Genotyping of COX-2 polymorphisms was carried out through PCR-RFLP in 200 CP cases and 200 controls. For risk estimation, binary logistic regression was applied using SPSS, version 15.0, while meta-analysis was carried using MIX 2.0 software. RESULTS None of the COX-2 polymorphisms independently were associated with the risk of CP. Meta-analysis suggested a significant reduced risk of CP with rs5275+8473 C allele and rs20417 in Chinese population. CONCLUSIONS No association was observed in any of the studied COX-2 polymorphisms with CP in North India. But, the study should be replicated in larger sample size to arrive at a definitive conclusion. Meta-analysis suggested a role of rs5275 COX-2 polymorphisms in susceptibility to overall CP, and on ethnic basis, rs20417 showed reduced risk of CP in Chinese population.

Abstract
RATIONALE Inflammation exacerbates a number of deleterious effects on the heart, most notable being left ventricular dysfunction (LVD). A promoter polymorphism of the NFKB1 gene (encodes p50 subunit) results in lower protein levels of NFkB p50 subunits, which in its dimmer (p50) form has anti-inflammatory effects. The active NFkB transcription factor promotes the expression of over 150 target genes including IL6 and TNF-α. Therefore, the aim of the present study was to assess the association of NFKB1, IL6 and TNF-α gene polymorphisms with LVD in coronary artery disease (CAD) patients. METHODS AND RESULTS The present study included a total of 830 subjects (600 CAD patients and 230 controls) and was carried out in two (primary and replication) cohorts. CAD patients with reduced left ventricle ejection fraction (LVEF ≤45%) were categorized having LVD. The NFKB1 -94 ATTG ins/del (rs28362491), IL6 -174 G/C (rs1800795) and TNF-α -308 G/A (rs1800629) polymorphisms were genotyped by PCR/ARMS-PCR methods. The results of the primary cohort were validated in a replicative cohort and pooled by meta-analysis using Fisher's and Mantel-Haenszel test. The analysis showed that NFKB1 ATTG/ATTG genotype was significantly associated with LVD (Fisher's method p-value=0.007, Mantel-Haenszel OR=2.34), LV end diastole (p-value=0.013), end systole (p-value=0.011) dimensions, LV mass (p-value=0.024), mean LVEF (p-value=0.001) and myocardial infarction (p-value=0.043). CONCLUSION Our data suggests that NFKB1 -94 ATTG ins/del polymorphism plays significant role in conferring susceptibility of LVD and ATTG/ATTG genotype may modulate risk of heart failure by increasing ventricular remodeling and worsening LV function.

Abstract
Background: Left ventricular dysfunction (LVD), followed by fall in cardiac output is one of the major complications in some coronary artery disease (CAD) patients. The decreased cardiac output over time leads to activation of the renin-angiotensin-aldosterone system which results in vasoconstriction by influencing salt-water homeostasis. Therefore, the purpose of the present study was to explore the association of single nucleotide polymorphisms (SNPs) in angiotensin I converting enzyme; ACE (rs4340), angiotensin II type1 receptor; AT1 (rs5186) and aldosterone synthase; CYP11B2 (rs1799998) with LVD. Methods and results: The present study was carried out in two cohorts. The primary cohort included 308 consecutive patients with angiographically confirmed CAD and 234 healthy controls. Among CAD, 94 with compromised left ventricle ejection fraction (LVEF ≤ 45) were categorized as LVD. The ACE I/D, AT1 A1166C and CYP11B2 T-344C polymorphisms were determined by PCR. Our results showed that ACE I/D was significantly associated with CAD but not with LVD. However, AT1 1166C variant was significantly associated with LVD (LVEF ≤ 45) (p value=0.013; OR=3.69), but CYP11B2 (rs1799998) was not associated with either CAD or LVD. To validate our results, we performed a replication study in additional 200 cases with similar clinical characteristics and results again confirmed consistent findings (p value=0.020; OR=5.20). Conclusion: AT1 A1166C plays important role in conferring susceptibility of LVD.

Abstract
PURPOSE Histogram Analysis in Radiation Therapy (HART) is an efficient and accurate dose-volume histogram (DVH) computational tool in radiotherapy research. Several applications of the program have been presented previously (J Appl Clin Med Phys 11(1): 3013, 2010; Med Phys 38(6), p.3678, 2011) for the Radiation Therapy Oncology Group (RTOG) users. The program has been further developed to incorporate various types of DVH analysis features to support the research using DICOM-RT plans. The main objective of this work was to present the improvement and compatibility of the program for the DICOM-RT plans. METHODS AND MATERIALS MATLAB based codes were primarily designed to read and write a simpler HART format from the standard DICOM-RT data objects exported from the Xio treatment planning system (CMS Inc., St. Louis, MO). This format employed an optimal polynomial fitting technique to interpolate the co-ordinates of the contours in the regions-of-interest. The format was efficient for the (a) precise extraction of the cumulative DVH (cDVH) and spatial DVH (sDVH; x-,y-, and z-DVHs respectively) data- statistics, (b) universal-plan indices evaluation, (c) biological modeling based outcome analyses (BMOA), (d) radiobiological dose-response modeling, and (e) physical parameterization modules. The fundamental DVH statistics were validated using the DVH statistics extracted from the Computational Environment for Radiotherapy Research program. RESULTS HART offers various types of DVH computational functionalities, several plan evaluation and radiobiological outcome analysis modules in a user- friendly software package for the RTOG and DICOM-RT planners. The cDVH and BMOA modules were found to be the most applicable features for the global researchers. CONCLUSIONS HART is a novel and universal multi-dimensional DVH analysis tool for the radiation therapy research. We further expect to develop HART for the space-time DVH analysis and proton therapy applications. The software is available online (http://www2.uic.edu/∼apyaku1) for the radiotherapy research. This work was partially supported by NIH-NIDCD grant.

Abstract
BACKGROUND The dose requirements for oral anticoagulants in thromboembolic events are influenced by promoter polymorphism in the VKORC1 gene. However, limited data are available on the influence of the polymorphism in various Indian populations. The present study aimed at determining the relationship between the VKORC1-1639 G>A genotypes and maintenance doses of oral anticoagulants for therapeutically stable INR values in patients taking Acitrom after valve replacement surgery. MATERIALS AND METHODS Fifty patients from the northern Indian region were genotyped for VKORC1-1639 G>A by polymerase chain reaction and restriction fragment length polymorphism. Means of the weight-normalized daily Acitrom dose were calculated for every patient. RESULTS AND DISCUSSION The VKORC1 1639G>A minor allele frequency in the study population (n = 50) was found to be 22%. The patients with a wild type genotype required the maximum drug dose as suggested for full functionality of the enzyme. Heterozygous patients were found to have an intermediate drug dose and the patients with a variant homozygous genotype had the minimum maintenance drug dose requirement. These findings are in concurrence with the effect of the promoter polymorphism on vitamin K epoxide reductase activity.1639G>A minor allele frequency in the study population (n = 50) was found to be 22%.

Abstract
BACKGROUND Primary spontaneous intracerebral hemorrhage (PSICH) is common in Asia and may have a genetic basis. OBJECTIVE To report the role of angiotensin-converting enzyme (ACE) and a ADDUCIN (ADD1) gene polymorphisms in patients with PSICH. SETTING Tertiary care teaching referral hospital. PATIENTS AND METHODS Study subjects included 104 patients with PSICH diagnosed by computed tomography (CT) brain scan and 198 controls. The vascular risk factors of stroke were noted. The location and size of the hematoma on CT scan were recorded. ACE (rs4646994) and a ADDUCIN (rs4961) gene polymorphisms were analyzed by polymerase chain reaction (PCR). The genotype and allele frequency were compared between patients and controls and within the PSICH group. RESULTS The median age of the PSICH group was 58 years, 17 (16.3%) patients were aged above 70 years and 40 (38%) were females. Ninety-three (91.2%) patients were hypertensive and 17 (16.5%) were diabetic. Hematoma was putaminal in 88 (84.5%), pontine in 5 (4.9%), cerebellar in 2 (1.9%), lobar in seven (6.8%) and multiple and primary intraventricular in one (1%) patient each. In the patients with PSICH, ACE DD genotype was present in 44 (42.8%) and ID in 40 (38.4%) whereas in controls these were 22 (11.1%) and 103 (52%) respectively. ADD1- WW genotype was found in two patients (1.9%), and GW in 44 patients (42.7%). In the controls these were found in nine (4.5%) and 65 (32.8%) respectively. DD genotype had 7.4 times higher risk of PSICH. ADD1 variant genotypes were not associated with increased risk but in association with ACE DD genotype resulted in significantly higher risk of PSICH. ACE and ADD1 variant genotypes were associated with nonlobar hematoma. CONCLUSION ACE DD genotype in isolation or in combination with ADD1 GW genotype is associated with PSICH, especially nonlobar hematoma.

Abstract
OBJECTIVE The present study was aimed to evaluate MTHFR C677T gene polymorphism in patients with ischemic stroke (IS) and intracerebral hemorrhage (ICH) and compare it with controls. METHODS 207 patient with IS and 215 with CT/MRI proven ICH were included and compared with 188 healthy controls. The stroke risk factors, location of IS, its vascular territory and in ICH the location of hematoma were noted. MTHFR C677T polymorphism was studied by polymerase chain reaction. RESULTS Hypertension was present in 65.9% of ICH and 48.8% of IS. Other stroke risk factors were not significantly different. The frequency of the CC genotype in controls was 68.6%. CT in 28.7% and TT in 2.7%, whereas it was 75.3%, 20.5% and 4.2% in ICH and 66.2%, 39.4% and 2.4% respectively in IS. The frequency of these genotypes as well as allele frequency was not different in IS, ICH as compared to controls, however variant allele was more frequent in IS compared to ICH. Homocysteine level was higher in IS patients with variant genotype INTERPRETATION MTHFR C677T gene polymorphism was neither associated with hemorrhagic nor ischemic stroke. However raised homocysteine levels were found to be associated with MTHFRC677-TT genotype in IS patients.

Abstract
We aimed to explore the single-locus, haplotype and epistasis patterns and the contribution of oestrogen receptor [ESR1 PvuII (rs2234693), ESR1 325 C→G (rs1801132)] and progesterone receptor [PROGINS (rs1042838)] polymorphisms in genetic susceptibility to migraine by analysing 613 subjects consisting of 217 migraine patients, 217 healthy controls (HC) and 179 patients with tension-type headache (TTH). Entire data were analysed by taking the Bonferroni corrected P-value into account. We found significant association of TT genotype [odds ratio (OR) 3.458, confidence interval (CI) 1.757, 6.806; P = 0.0003] and T allele (OR 1.729, CI 1.309, 2.284; P = 0.0001) of ESR1 PvuII single nucleotide polymorphism with migraine when compared with HC. Significant association was seen only in female migraine patients at both genotype (P = 0.002; OR 3.834, CI 1.625, 9.043) and allele level (P = 0.002; OR 1.721, CI 1.228, 2.413). Moreover, higher risk was limited to migraine with aura (MA) (in case of TT genotype, P = 0.002; OR 4.377, CI 1.703, 1.246; in case of T allele, P = 0.001; OR 1.888, CI 1.305, 2.735) rather than migraine without aura (MoA) (P-value of TT genotype = 0.003; OR 3.082, CI 1.465, 6.483; P-value T allele = 0.002; OR 1.630, CI 1.188, 2.236). In case of a recessive model, risk was seen with migraine patients (P = 0.0003; OR 2.514, CI 1.635, 3.867), MA (P = 0.0001; OR 3.583, CI 1.858, 6.909) and MoA patients (P = 0.002; OR 2.125, CI 1.304, 3.464) when compared with HC. No risk was observed when TTH patients were compared with HC. No significance of ESR 325 G→C polymorphism was seen in any of the models under study. Significant differences in genotypic (P = 0.0001) and allelic frequency (P = 0.0002) were seen in case of PROGINS polymorphism when migraine patients were compared with HC, showing a protective effect (for A1A2 genotype, OR 0.292, CI 0.155, 0.549; for A2 allele, OR 0.320, CI 0.174, 0.589). Moreover, significance was seen only in case of female migraine patients at genotype (P = 0.002; OR 0.344, CI 0.176, 0.684) as well as allele levels (P = 0.004; OR 0.379, CI 0.198, 0.727) in case of PROGINS polymorphism. ESR1 PvuII TT*ESR1 325 C→G CG genotype, PROGINS A1A2*ESR1 325 C→G CG genotype and ESR1 PvuII CT*PROGINS A1A2 interacted significantly, but significance was lost after Bonferroni correction. In conclusion, ESR1 PvuII polymorphism is a significant risk factor for migraine particularly in women and MA patients, but ESR 325 C→G polymorphism is not associated with migraine susceptibility. PROGINS polymorphism seems to play a protective role in genetic susceptibility to migraine in the North Indian population.

Abstract
Decreased expression due to genetic variations in complement receptor 1 (CR1) on erythrocytes might result in reduced clearance of immune complexes, conferring interindividual variation for gallbladder cancer (GBC) susceptibility. We studied role of CR1 (A(3650)G RsaI and Intron 27 HindIII) polymorphisms in gallstone disease and GBC in north Indian population. Study included 185 GBC patients, 185 gallstone patients and 200 controls. Genotyping was done by PCR-RFLP. Result showed GG genotype and G allele of CR1 A(3650)G RsaI were conferring significant risk for GBC [(P = 0.022; OR = 1.94; 95% CI = 1.1-3.4) and (P = 0.035; OR = 1.35; 95% CI = 1.0-3.8) respectively]. Also, comparison of GBC patients with gallstone patients showed increased risk for GBC in presence of GG genotype and G allele GBC (P = 0.048; OR = 1.74; 95% CI = 1.0-3.0) and (P = 0.027; OR = 1.39; 95% CI = 1.0-1.8) respectively. No association of CR1 A(3650)G RsaI polymorphism was observed when gallstone patients were compared with controls. CR1 Intron 27 HindIII polymorphism was not associated with GBC and gallstone susceptibility. Haplotype analysis showed increased risk of GBC in presence of G,L haplotype (P = 0.046; OR = 1.35: 95% CI = 1.0-1.8). Subgroup stratifications on basis of gender and gallstone status showed GG genotype of CR1 A(3650)G RsaI polymorphism imparted high risk for GBC in females (P = 0.043; OR = 1.99: 95% CI = 1.4-3.9). Also there was increased risk for GBC in presence as well as absence of gallstones (OR = 1.85 and 1.76 respectively), but it was not statistically significant. We conclude that CR1 A(3650)G RsaI polymorphism plays an important role in conferring genetic susceptibility to gallbladder cancer GBC in north Indian population.

Abstract
OBJECTIVE To evaluate the role of ACT gene polymorphism in primary spontaneous intracerebral hemorrhage (PSICH) and ischemic stroke (IS). METHODS 193 PSICH, 272 IS and 188 controls were included from the same geographical area. The demographic and clinical stroke risk factors were noted. PSICH was confirmed by CT and IS by MRI. The location of stroke and size were noted. ACT gene polymorphism was analyzed by polymerase chain reaction. The ACT genotype and allele frequency in PSICH, IS and controls were compared. RESULTS The age of the PSICH was 56.9+/-13 years, IS 54+/-16.7 years and controls 54.8+/-10 years. 134 females were in study and 65 in control groups. In the controls the AA genotype was 30%, AT 51.1% and TT in 16% whereas these were 39.3%, 53% and 7.7% in PSICH and 34.6%, 53.3% and 12.1% in IS. The frequency of T allele in controls was 41.5%, PSICH 34.2% and IS 38.6%. There was no significant difference in genotype and allele frequency in PSICH, IS and controls as well as location and etiology of stroke. INTERPRETATION The ACT genotype and allele frequency are not different in Indian PSICH and IS compared to controls.

Abstract
e19505 Background: Primary cutaneous lymphomas occur in 0.5 to 1 per 100,000 people every year in developed countries. Less than 1,000 cases of Mycosis Fungoides are diagnosed each year in the United States, with approximately 3 cases per 1,000,000 per year. Cutaneous T-cell lymphomas are responsive to radiation therapy, and local radiation therapy, total skin electron beam therapy, phototherapy (with UVB or PUVA), chemotherapy agents (nitrogen mustards, BCNU), retinoids, and steroids have all been used with varying degrees of success. Methods: This is a retrospective review of all cases of histology-proven cutaneous T-cell lymphoma treated with single-fraction radiation therapy at Northwestern Memorial Hospital in the Department of Radiation Oncology since 1990. We looked at response to treatment and local control. We reviewed the charts of 67 patients with cutaneous T-cell lymphoma, of which 40 patients and a total of 130 sites of disease received single-fraction radiation therapy and had available follow-up data. Results: Of the 130 lesions receiving a single-fraction of radiation, 86 (66%) received 800cGy in 1 fraction and 38 (29%) received 700cGy. 4 patients (3%) received 750cGy, 1 (<1%) received 550cGy and 1 (<1%) received 500cGy. Patients were treated with electron energies ranging from 6–18 MeV or photon energies ranging from 4–10 MV. Out of 130 lesions, 119 (92%) achieved a complete response (CR) to single-fraction radiation and 11 (8%) achieved a partial response (PR). There were 2 sites of relapse out of 130 treated sites, involving 2 patients. The median follow-up time was 4 months, mean follow-up time was 14 months, and 44% of patients had greater than 6 months of follow-up. Conclusions: This review of the experience at our institution since 1990 shows single-fraction radiation therapy to be an effective treatment for cutaneous T-cell lymphoma, with high response rates and very low relapse rates. No significant financial relationships to disclose.

Abstract
BACKGROUND DNA damage by endogenous or exogenous source of reactive oxygen species (ROS) plays an important role in induction and progression of various cancers. Physiologically, gallbladder is likely to be exposed to various ROS which leads to extensive DNA damage. Cells overcome the DNA damage by repair mechanisms. Genetic variants of OGG1 and XRCC1, important enzymes participating in base excision repair pathway, may confer interindividual variations in susceptibility to gallbladder cancer (GBC). This study was aimed to examine the role of OGG1 Ser326Cys (rs1052133) and XRCC1 Arg194Trp (C > T) (rs25487) and Arg399Gln (G > A) (rs1799782) polymorphisms in GBC susceptibility. METHODS The study included 173 GBC patients and 204 controls. Genotyping was done by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method. Differences in the frequencies were estimated by chi-square test and risk was estimated by using unconditional logistic regression after adjusting for age and gender. RESULTS OGG1 Cys/Cys genotype frequency was significantly higher in GBC patients [odds ratio (OR) = 2.93; 95% confidence interval (CI) = 1.14-7.51]. The increased risk was more pronounced in female GBC patients (OR = 5.92; 95%CI = 1.20-29.13), patients with gallstone (OR = 5.50; 95%CI = 1.99-15.16), female gender, and late onset of disease (OR = 4.72, 95%CI = 1.43-15.53). In XRCC1 Arg399Gln polymorphism, significant differences in frequencies of Gln/Gln and Arg/Gln genotypes conferred significantly low risk for GBC (OR = 0.62; 95%CI = 0.39-0.97 and OR = 0.37; 95%CI = 0.19-0.71 respectively). However, XRCC1 Arg194Trp polymorphism was not associated with GBC. The carriers of Arg-Gln haplotype consisting of 194Arg and 399Gln alleles of XRCC1 were also at significant low risk for GBC (OR = 0.59, 95%CI = 0.42-0.82). Interaction of genotypes and tobacco usage did not modulate the risk. CONCLUSION Results suggest that Cys/Cys genotype of OGG1 Ser326Cys polymorphism is associated with increased risk of GBC. However, Arg399Gln polymorphism and Arg-Gln haplotype comprising XRCC1 Arg194Trp and Arg399Gln polymorphisms conferred low risk for GBC susceptibility.

Abstract
Multiple drug resistance is a common problem in the treatment of epilepsy, and approximately 30% of patients continue to have seizures despite all therapeutic interventions. Among various classes of drug transporters, genetic variants of P-glycoprotein (P-gp) encoded by the ABCB1 (ATP-binding cassette subfamily B member 1) gene have been associated with drug-refractory epilepsy. Our aim was to investigate the effect of the 1236C>T(rs1128503), 2677G>T/A(rs2032582), and 3435C>T(rs1045642) single-nucleotide polymorphisms of ABCB1 (or MDR1) on drug resistance in north Indian patients with epilepsy. Genotyping was performed in 101 control subjects and 325 patients with epilepsy, of whom 94 were drug resistant and 231 drug responsive. Therapeutic drug monitoring for phenytoin, carbamazepine, phenobarbital, and valproate was also performed to confirm compliance in 20% of the patients. Genotype and haplotype frequencies of these polymorphisms did not differ between drug-resistant and drug-responsive patients. Our results demonstrate ABCB1 polymorphisms are not associated with drug resistance in north Indian epileptic patients.

Abstract
The glutathione S-transferase (GSTs) are polymorphic supergene family of detoxification enzymes that are involved in the metabolism of numerous potential carcinogens. Several allelic variants of polymorphic GSTs show impaired enzyme activity and are suspected to increase the susceptibility to various cancers. To find out the association of GST variants with risk of gallbladder cancer, the distribution of polymorphisms in the GST family of genes (GSTT1, GSTM1, GSTP1, and GSTM3) were studied in 106 cancer patients and 201 healthy controls. Genotypes were analysed by polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (RFLP). The frequencies of GSTM1 null and GSTM3*BB genotypes did not differ between patients and controls. The overall frequency of GSTT1 null was lower in cases as compared with controls (p=0.003, Odds ratio (OR) = 0.2, 95% confidence interval (CI), 0.1-0.6). After sex stratification, the GSTT1 null frequency was reduced only in female patients (p=0.008, OR = 0.2, 95% CI = 0.1-0.6). However, the GSTP1, ile/val genotype and the val allele were significantly higher in cases than controls (p=0.013, OR = 1.9, 95% CI = 1.1-3.1; p=0.027, OR = 1.5, 95% CI = 1.0-2.1), respectively. To study gene-gene interactions, a combined risk of gallbladder cancer due to ile/val or val/val were calculated in combination with null alleles of GSTM1 and GSTT1 or the *B allele of GSTM3, but there was no enhancement of risk. Gallstones were present in 57.5% of patients with gallbladder cancer, but there were no significant differences between allelic/genotype frequencies of the studied GST genes polymorphisms between patients with or without gallstones. To best of our knowledge, this is the first paper showing ile/val genotypes and val allele of GSTP1 to be associated with higher risk of gallbladder cancer.

Abstract
OBJECTIVE Helicobacter pylori infection causes gastritis, lymphoid follicle formation and development of MALT lymphoma. We evaluated endoscopic, histological, serological and genetic risk factors associated with lymphoid follicle development in gastritis. MATERIALS AND METHODS After upper GI endoscopy, 3 antral biopsies were taken from 120 patients for histological examination. H. pylori was diagnosed using rapid urease test (RUT), modified Giemsa stain and IgG anti-CagA ELISA. Genotyping of IL-1B (-511C/T) and IL-1RN (86 bp VNTR) genes were performed by PCR-RFLP/PCR. RESULTS In 120 patients, 45 (37.5%) showed presence of lymphoid follicles in antral gastric mucosa. H. pylori was positive by modified Giemsa stain (26%) RUT (50%) and anti-CagA IgG in 67.5%, The presence of nodularity (p = 0.030), neutrophilic infiltration (p = 0.010), lymphocytic infiltration (p = 0.002), glandular atrophy (p = 0.0001), glandular shortening (p = 0.001), fibrosis (p = 0.0001), plasma cells (p = 0.007), eosinophils (p = 0.012), anti-CagA antibodies (p = 0.003) and H. pylori density (p = 0.020) were associated with risk (odds ratio = 11.5, 3.8, 11.0, 8.4, 3.8, 4.6, 5.8, 16.0, 10.8 and 2.8 respectively) of lymphoid follicle. However, IL-1 gene polymorphisms did not influence lymphoid follicle development CONCLUSION The presence of modularity, lymphocytic infiltration, glandular atrophy, glandular shortening, fibrosis, plasma cells, eosinophils and anti-CagA IgG antibodies are risk factors for lymphoid follicle development in patients with gastritis.

Abstract
INTRODUCTION Prostate cancer is common around the world, but rates of advanced disease differ substantially by race and geography. Although a major health issue, little is known about prostate cancer presentation in West Africa and India compared to the United States (US). OBJECTIVE The aim of this study was to compare prostate tumor characteristics in four populations of men from the US, Senegal and India. MATERIALS AND METHODS We recruited prostate cancer patients from four hospital-based populations. The sample included 338 African-Americans, 1265 European-Americans, 122 Asian Indians, and 72 Senegalese. Questionnaire and medical record data were collected on each participant. RESULTS We found significant differences in age at diagnosis, BMI, and PSA levels across the groups. Senegalese and Indian men had a higher probability of high stage (T3/T4) disease compared to US men. Gleason grade was significantly higher in Asian Indians compared to other populations. African-Americans, Senegalese, and Asian Indians had a significantly higher probability of metastatic disease compared to European Americans. The odds ratios (OR) for metastasis were consistently higher in Asian Indians compared to American cases. As only 19/72 Senegalese were assessed for metastasis, OR could not be determined for metastasis. CONCLUSIONS These results suggest that there are significant geographical and ethnic differences in the presentation of prostate cancer. Men in developing countries tend to present with advanced disease compared to US men. Identifying risk factors for advanced disease may help to decrease the rate of poor prostate cancer outcomes and associated mortality worldwide.

Abstract
Inflammation of gallbladder is an established risk factor for gallbladder cancer (GBC) pathogenesis. Chemokine receptors play crucial role in antitumour immunity and are involved in inflammation and pathogenesis of cancers. Present study was aimed to examine the role of CCR5 Delta32 polymorphism in conferring genetic susceptibility to GBC. Present case-control study included 144 proven GBC patients and 210 healthy controls. Genotyping was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Statistically significant difference was observed in distribution of CCR5+/Delta32 genotype (P = 0.028) [odds ratio (OR) = 2.850; 95% confidence interval (CI) = 1.1-7.2] and CCR5 Delta32 allele (P = 0.012) (OR = 3.145, 95% CI = 1.2-7.7) in GBC patients which was conferring high risk. Stratification of GBC patients showed significant association of CCR5+/Delta32 genotype and CCR5 Delta32 allele with GBC patients with and without gallstones. Analysis based on age of onset and gender suggested significant association of CCR5 Delta32 allele with early onset (<50 years) of the disease but only marginal influence of gender in CCR5 Delta32-mediated risk of cancer. Risk was further modulated by tobacco usage and significantly increased risk was observed in tobacco users with CCR5+/Delta32 genotype. In conclusion, CCR5+/Delta32 genotype and CCR5 Delta32 allele confer significant risk for GBC particularly in patients with early onset and tobacco usage. Role of CCR5+/Delta32 polymorphism in GBC susceptibility is independent of gallstone formation.

Abstract
BACKGROUND We evaluated the association of functional variants of IL-1 genes with the development of gastritis and precancerous lesions, which are known to be influenced by inflammatory response against Helicobacter pylori. METHODS After upper gastrointestinal (GI) endoscopy, 120 patients with gastritis were tested for H. pylori infection using rapid urease test, modified Giemsa staining and IgG anti-CagA ELISA. All patients and 243 healthy controls were genotyped for IL-1B (-511 C/T) and IL-IRN (VNTR) genes using PCR-RFLP/PCR. RESULTS IL-1B: (-511 C/T) genotype/allele were not associated with gastritis. IL-1RN 1/2 genotype carriers had susceptibility to gastritis (p=0.025, OR=1.7). Individuals with the IL-1RN 1/1 genotype (p=0.05, OR=0.65) and IL-1B -511*T-IL-1RN *1 haplotype were at low risk for gastritis (p=0.043, OR=0.72). High secretor haplotype combinations (C1-/T2+, C1-T1+ and T1+/T2+) did not influence neutrophilic infiltration, glandular atrophy or intestinal metaplasia. CONCLUSIONS We identified that individuals with the IL-1RN 1/2 genotype had increased risk for gastritis. IL-1B -511*T-IL-1RN *1 (T1) haplotype carriers were at decreased risk for gastritis and no significant association was observed for precancerous lesions in North Indians.

Abstract
OBJECTIVE The objective of the study was to evaluate the influence of genetic polymorphisms of GSTM1, GSTT1, and GSTM3 on the susceptibility of cervical cancer. STUDY DESIGN Blood samples from 150 women with biopsy-confirmed cervical cancer and 168 healthy controls were analyzed by multiplex polymerase chain reaction (PCR) to detect the presence or absence of GSTM1 and GSTT1. Insertion/deletion polymorphism in intron 6 of GSTM3 was determined by PCR. RESULTS The frequencies of homozygous GSTM1 null and GSTT1 null genotypes were found to be significantly higher in cancer patients as compared with healthy controls (P = .009, odds ratio [OR] 1.52, 95% confidence interval [CI], 1.1 to 2.0 and P = .0004, OR 2.4, 95% CI: 1.4 to 4.0, respectively). The AB genotype of GSTM3 also conferred higher risk of cancer (P = .053, OR 1.64, 95% CI, 1.0 to 2.6). However, no significant association of at-risk genotypes was observed with any stages of cervical cancer. Interactions among GSTM1 null, GSTT1 null, and AB genotype of GSTM3 resulted in additive predictive risks of cervical cancer. In case-only analysis, carriers of the AA genotype of GSTM3 among tobacco users were at elevated risk of cervical cancer (P = .024, OR 2.1, 95% CI, 1.0 to 4.1) as compared with AB and BB genotypes. CONCLUSION GSTM1 null, GSTT1 null, and GSTM3*AB genotypes may confer higher susceptibility to cervical cancer and cancer risk because at-risk genotypes are additive. Tobacco usage by carriers of GSTM3*AA has enhanced the risk of cervical cancer as compared with nonusers.

Abstract
PURPOSE The incidence of gallbladder cancer (GBC) is usually paralleled by the prevalence of gallstone disease, and genes of cholesterol metabolism have been implicated in gallstone disease. The XbaI and insertion/deletion (ins/del) polymorphism of Apolipoprotein B (APOB) appears to influence cholesterol homoeostasis and possibly risk for gallstone disease. We examined the effect of these polymorphisms individually as well as their haplotypes on GBC and gallstone patients in North Indian population. METHODS The study comprises 123 consecutive cases of proven GBC, 172 cases of gallstone and 232 healthy subjects of similar age and sex. The genomic DNA was extracted from peripheral blood leucocytes and genotyping was performed using polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism. RESULTS In a case-control study, APOB XbaI and ins/del polymorphisms were not significantly associated with risk of GBC. Using the expectation maximization algorithm, four haplotypes were obtained, and haplotype X(+),D was found to be significantly higher in GBC patients without stone in comparison with healthy subjects [odds ratio (OR) 2.9, 95% confidence interval 1.2-6.6 P=0.012]. CONCLUSIONS The X(+),D haplotype of APOB is associated with increased risk for development of GBC and the risk is not modified in the presence of gallstones.

Abstract
INTRODUCTION Helicobacter pylori (H. pylori) infection is associated with divergent clinical outcomes and these outcomes are largely influenced by the levels of cytokines in the gastric mucosa. The levels of these cytokines are dependant on cytokine gene polymorphisms. Pro-inflammatory cytokine polymorphisms are strongly associated with severe histological changes in the gastric mucosa in Caucasian populations. METHODS In this study, we evaluated the role of cytokine gene polymorphisms in influencing the pathological severity of gastritis. 120 patients were evaluated. Cytokine gene polymorphisms of interleukin-1 (IL-1) beta, tumour necrosis factor alpha and the IL-1 receptor antagonist genes were done using polymerase chain reaction (PCR) restriction fragment length polymorphism and PCR variable number of tandem repeats markers typed on the deoxyribonucleic acid obtained from the peripheral blood. Histological analysis was done by using the revised Sydney system. RESULTS There was no association between pro-inflammatory cytokine gene polymorphisms and severity of gastritis. CONCLUSION This data suggests that high cytokine levels are not seen in the gastric mucosa in Indians in spite of H. pylori colonisation. IL-1 beta is a potent proinflammatory cytokine which causes a partial clearance of the organism as well as hypochlorhydria. Corporal hypochlorhydria causes a persistent colonisation by H. pylori followed by the development of gastric atrophy and later carcinoma. This lack of association with a pro-inflammatory polymorphism suggests that only low levels of IL-1 beta are present in the gastric mucosa. This causes a low clearance of the organism and a high incidence of duodenal ulceration because of hyperchlorhydria. However, it is protective against the development of gastric carcinoma. This would explain the "Indian Paradox" of the apparent discrepancy of a high degree of colonisation by H. pylori and a low incidence of gastric carcinoma in the Indian population.

Abstract
The role of mast cells and eosinophils in influencing the pathology of chronic gastritis remains unclear. We attempted to study the relationship between endoscopy and the mast cell and eosinophil infiltrate. We also studied the role of gene polymorphisms, Helicobacter pylori density and the CagA antibody status in influencing the mast cell and eosinophil infiltrate. One hundred and twenty consecutive patients were studied. Endoscopic evaluation was done and 3 antral biopsies were taken from each patient and were assessed for eosinophilic and mast cell infiltration, H. pylori density and the density of the other inflammatory cells as per the revised Sydney system. Cytokine gene polymorphisms (IL-1beta, IL-1RA and TNF-alpha) were done on the DNA extracted from the peripheral blood by PCR-RFLP. ELISA was done on the patients' serum for the anti-CagA antibody titres. Nodularity is strongly associated with the presence and density of eosinophils on biopsy (P < 0.05). Eosinophil density is strongly associated with the density of H. pylori, neutrophils, lymphocytes, plasma cells, atrophy, ulceration, foveolitis and lymphoid follicles. The mast cell density is not associated with any of the other histopathological variables. Gene polymorphisms and the CagA antibody titres have no relationship to the mast cell and eosinophil density. Eighty-one patients showed positive anti-CagA antibody titres but there was no association with the eosinophilic or the mast cell infiltrate. It is likely that eosinophilic infiltration is influenced by the H. pylori density but the CagA protein has no role to play in influencing the grade of the eosinophilic infiltrate in the Indian context. Cytokine gene proinflammatory polymorphisms have no role to play in influencing the eosinophilic or the mast cell response. It is likely that other mediators are involved in the inflammatory cell responses.
