RESUMO

Rejuvenation of deteriorated host immune functions is imperative for successful annihilation of Leishmania parasites. The use of immunomodulatory agents may have several advantages as they conquer immunosuppression and, when given in combination, improve current therapeutic regimens. We herein investigated the immunostimulatory potency of a ß-glucan, lentinan either alone or in combination with short dose of standard drug, miltefosine on Leishmania-infected J-774A.1 macrophages. Our study shows that infected macrophages when stimulated with 2.5 µg/mL and above concentrations of lentinan secreted significant amount of host-protective molecules. The in vitro interaction between lentinan and miltefosine showed some synergy (mean sum of fractional inhibitory concentration [mean ∑FIC] 0.87) at IC50 level. Lentinan (2.5 µg/mL) plus low-dose miltefosine (2 µM) displayed heightened level of pro-inflammatory cytokines, IL-12 (13.6-fold) and TNF-α (6.8-fold) along with nitric oxide (7.2-fold higher) when compared with infected control. In combination group, we also observed remarkably (P<.001) suppressed levels of anti-inflammatory cytokines, IL-10 and TGF-ß, than that of untreated macrophages. Additionally, in comparison with infected group, we observed significant induction in phagocytic activity of macrophages in combination with treated group. Collectively, these findings emphasize the immunostimulatory effect of lentinan alone and in combination with low dose of miltefosine against Leishmania donovani.

RESUMO

OBJECTIVES: To study correlation between ovarian reserve with biophysical markers (antral follicle count and ovarian volume) and biochemical markers (S. FSH, S. Inhibin B, and S. AMH) and use these markers to predict poor ovarian response to ovarian induction. METHODS: This is a prospective observational study. One hundred infertile women attending the Obst & Gynae Dept, KGMU were recruited. Blood samples were collected on day 2/day 3 for assessment of S. FSH, S. Inhibin B, and S. AMH and TVS were done for antral follicle count and ovarian volume. Clomephene citrate 100 mg 1OD was given from day 2 to 6, and patients were followed up with serial USG measurements. The numbers of dominant follicles (> or = 14 mm) at the time of hCG administration were counted. Patients with <3 follicles in the 1st cycle were subjected to the 2nd cycle of clomephene 100 mg 1OD from day 2 to day 6 with Inj HMG 150 IU given i.m. starting from day 8 and every alternate day until at least one leading follicle attained ≥18 mm. Development of <3 follicles at end of the 2nd cycle was considered as poor response. RESULTS: Univariate analyses showed that s. inhibin B presented the highest (ROCAUC = 0.862) discriminating potential for predicting poor ovarian response, In multivariate logistic regression model, the variables age, FSH, AMH, INHIBIN B, and AFC remained significant, and the resulting model showed a predicted accuracy of 84.4 %. CONCLUSION: A derived multimarker computation by a logistic regression model for predicting poor ovarian response was obtained through this study. Thus, potential poor responders could be identified easily, and appropriate ovarian stimulation protocol could be devised for such pts.

RESUMO

BACKGROUND AND OBJECTIVES: Vertical augmentation is necessary in cases of extensive resorption of alveolar ridge for dental implants placement and esthetic prosthetic rehabilitation. Several surgical techniques have been used to increase bone height including distraction osteogenesis, and particulate or block bone graft. This study was done to describe the evolution of "tentpole technique" and to review the literature related to this technique and thus evaluate its effectiveness to augment large vertical alveolar ridge defects for implant placement. MATERIAL AND METHODS: The evidence was obtained by PubMed and Google search using key words: tentpole technique, ridge resorption, and alveolar ridge augmentation . The years of search included from 2002 till 2013. RESULTS: The technique was described as effective on review of outcome of existing studies. It was found that considerable and stable increase in alveolar ridge height was achieved using tentpole technique. CONCLUSIONS: Tenting of periosteum and soft tissue matrix maintains space and enhances the effectiveness of bone graft. This technique offers predictable functional and esthetic reconstruction of large vertical alveolar defects.

RESUMO

Adverse side effects and drug resistance issues are the two most important drawbacks which influence the widespread use of existing antileishmanial drugs. Use of immune stimulating agent with standard antileishmanial might be helpful to minimize the toxic effect of drug, shorten the dose regimen and delay the emergence of resistance. In the present study, we explored the in vitro immunomodulatory potential of an immunomodulator, leptin with lower concentration of standard drug, miltefosine. The level of Th1/Th2 cytokines, production of nitric oxide and reactive oxygen species and phagocytic activity was assessed by ELISA, Griess reaction and flow cytometric analysis, respectively. Leptin at a concentration of 15µg/mL showed heightened level of Th1 cytokines and nitric oxide generation from murine macrophages (J-774A.1 cells). Leptin (15µg/mL) also reduces the effective concentration of miltefosine by 2-folds from 7.5µM to 3.7µM. When given in conjunction with lower concentration of miltefosine (4µM), leptin (15µg/mL) significantly (***p<0.001) elevated the level of IL-12 (7.7 fold), TNF-α (8.1 fold) and nitric oxide (6.6 fold) along with markedly (***p<0.001) suppressed level of IL-10 and TGF-ß when compared with untreated infected macrophages. Leptin plus miltefosine also induces the phagocytic ability (**p<0.01) of macrophages in comparison to leptin alone and miltefosine alone treated groups. These finding illustrate that leptin activates host macrophages to generate protective immune response for the successful elimination of Leishmania parasite at lower concentration of miltefosine and has potential for further exploration in experimental animal model of visceral leishmaniasis (VL).

RESUMO

BACKGROUND AND OBJECTIVE: Nutritional imbalance, combined with endocrine abnormalities, may be involved in the pathogenesis of osteoarthritis (OA). This study was conducted to determine the association of OA with dietary factors, such as quantity and quality of nutrient intake. METHODS: This case-control study enrolled 180 knee osteoarthritis (KOA) subjects who met the American College of Rheumatology definition of KOA, with an equal number of matched controls. Outcome measures, such as dietary nutrient intake and its frequency, were recorded using a food frequency questionnaire. RESULTS: Compared to controls, cases were older individuals with a higher body mass index (BMI). Physical activity scores were lower in female cases compared to male cases and controls. A significantly higher intake of phosphorus and fat was observed in overall cases (fat in females only). A significantly lower intake of vitamin C and vitamin D was observed in overall cases and the significance of vitamin D persisted on gender-wise bifurcation. On multiple logistic regression analysis, the intake of vitamin D (odds ratio [OR] = 0.79) and vitamin C (OR = 0.97) was inversely associated with the presence of KOA in the observation group, especially in females. Generally, the intake of food servings/day, green leafy vegetables (GLVs), and fats/oils was higher, whereas the intake of fruits, milk/milk products, and meat/poultry was lower in cases compared to controls. CONCLUSION: Low intake of vitamin D and vitamin C is a possible risk factor for KOA. Certain food groups, such as fruits, milk/milk products, and meat/poultry are beneficial for KOA. Further studies are needed to elucidate the associations between diet and KOA.

RESUMO

OBJECTIVE: Genetic variants of the melanocortin-4 receptor gene (MC4R), agouti related protein (AGRP) and proopiomelanocortin (POMC) are reported to be associated with obesity. Therefore, the aim of this study is to examine MC4R rs17782313, MC4R rs17700633, AGRP rs3412352 and POMCrs1042571 for any association with obesity in North Indian subjects. METHODS: The variants were investigated for association in 300 individuals with BMI ≥30 kg/m(2) and 300 healthy non-obese individuals BMI <30 kg/m(2.) The genotyping were analyzed by Taqman probes. The statistical analysis was performed by the SPSS software, ver.19 and p≤0.05 was considered statistically significant. RESULTS: The genotypes of MC4R rs17782313 and POMC rs1042571 were significantly associated with obesity (C), (p=0.02; OR=1.7 and p=0.01; OR=1.6, respectively); however, MC4Rrs17700633 (p=0.001; OR=0.55) was associated with low risk. In addition, AGRPrs3412352 (p=0.93; OR=0.96) showed no association with obesity (BMI ≥30 kg/m(2)) in North Indian subjects. CONCLUSION: This study provides the report about the significant association of MC4R (rs17782313) and POMC (rs1042571) with morbid obesity (BMI ≥30 kg/m(2)), but MC4R (rs17700633) and AGRP (rs34123523) did not show any association with obesity in the studied North Indian population.

RESUMO

INTRODUCTION: Filarial chyluria is a common problem in filarial endemic countries. Its management begins with medical therapy but some patients progress to require surgery. The present study aimed to determine factors affecting response to medical management in patients of filarial chyluria. MATERIALS AND METHODS: This prospective study conducted between August 2008 and November 2012, included conservatively managed patients of chyluria. Demographic profile, clinical presentation, treatment history and urinary triglycerides (TGs) and cholesterol levels at baseline were compared between the responders and non-responders. Apart from the clinical grade of chyluria, hematuria was evaluated as an independent risk factor. RESULTS: Out of the 222 patients (mean age, 37.99 ± 13.29 years, 129 males), 31 patients failed to respond while 35 had a recurrence after initial response; the overall success rate being 70.3% at a mean follow-up of 25 months. No difference was observed in demographics, clinical presentation, presence of hematuria, disease duration and mean urinary TGs loss between responders and non-responders. On multivariate analysis, patients with treatment failure were found to have a higher-grade disease (14.3% Grade-I, 36.6% Grades-II and 60% Grade-III), higher number of pretreatment courses (1.59 ± 1.08 vs. 1.02 ± 0.79) and heavier cholesterol (26.54 ± 23.46 vs. 8.81 ± 8.55 mg/dl) loss at baseline compared with responders (P < 0.05). CONCLUSION: Conservative management has a success rate in excess of 70%, not affected by the disease chronicity, previous episodes and recurrent nature. However, higher-grade disease, extensive pre-treatment with drugs and higher urinary cholesterol loss at baseline are the predictors of poor response. Hematuria is not an independent poor risk factor for conservative management.

RESUMO

BACKGROUND: Drug resistant tuberculosis (DRTB) is an emerging problem that adversely affects treatment outcomes and public health in the developing world. OBJECTIVE: To determine the initial drug resistance pattern among pulmonary tuberculosis patients registered under the Revised National Tuberculosis Control Programme. STUDY DESIGN: A cross-sectional study design. SETTING: Two urban Directly Observed Treatment Supervised (DOTS) centres in Lucknow District of Uttar Pradesh. METHODS: The present study consisted of newly diagnosed sputum smear-positive for acid-fast bacilli (AFB) cases at the time of registration under the tuberculosis control programme. All sputum smear positive cases were subjected to culture and drug-susceptibility testing by 1% proportion method on Lowenstein-Jensen (LJ) medium. RESULTS: A total of 185 newly diagnosed sputum smear positive for AFB i n pulmonary tuberculosis patients weresubjected to culture and drug sensitivity test. Among 185 isolates, 170 (91.4%) isolates were culture positive. Of these 170 isolates, 169 (99.4%) were M. tuberculosis and one (0.5%) was Mycobacterium other than tuberculosis (MOTT). Out of 99.4% M. tuberculosis positive isolates, 21.3% were resistant to at least one drug. Resistance pattern of 21.3% strains of M. tuberculosis showing resistance to single, double, triple, and quadruple drugs were 5.9%, 10.7%, 2.4% and 2.4% respectively. Multi-drug resistance (MDR) was observed in 4.7% isolates. CONCLUSION: The present study highlights the high rate of drug resistance pattern among the new sputum smear positive pulmonary tuberculosis patients and also high MDR tuberculosis. Routine surveillance of drug resistance profile of patients provides useful information for adopting new strategies of effective treatment within National Tuberculosis Control Programmes in order to combat the threat of MDR-TB in the general population.

RESUMO

BACKGROUND: Animal, epidemiologic, and human clinical studies suggest a putative role for vitamin D in osteoarthritis (OA). Inadequate sunlight exposure and lower serum levels of 25(OH)D appear in some reports to be associated with an increased risk for progression of knee OA. QUESTIONS/PURPOSES: We asked whether treatment with vitamin D would (1) reduce knee pain (WOMAC and VAS), (2) improve function (WOMAC), and (3) change levels of relevant biochemical markers in patients with knee OA with vitamin D insufficiency. METHODS: This randomized controlled pilot trial prospectively enrolled 107 patients with knee OA with vitamin D insufficiency (25(OH)D ≤ 50 nmol/L) to receive oral vitamin D or placebo. The primary outcome measures were pain and function, and the secondary were biochemical markers. At baseline, the two groups were comparable. The patients were followed for 1 year. RESULTS: At 12 months, knee pain had decreased in the vitamin D group by mean -0.26 (95% CI, -2.82 to -1.43) on VAS and -0.55 (95% CI, -0.07 to 1.02) on the WOMAC, whereas in the placebo group, it increased by mean 0.13 (95% CI, -0.03 to 0.29) on the VAS and 1.16 (95% CI, 0.82 to 1.49) on the WOMAC (effect size = 0.37 and 0.78). Likewise knee function improved in the vitamin D group by mean -1.36 (95% CI, -1.87 to -0.85) over the placebo group which had a mean 0.69 (95% CI, -0.03 to 1.41; effect size = 0.06). There were significant biochemical changes in serum total calcium, 25(OH)D and alkaline phosphatase. CONCLUSIONS: The results above suggest there is a small but statistically significant clinical benefit to vitamin D treatment in patients with knee OA, although we recommend a long-term study to determine whether these changes are clinically important and whether they will be sustained with time. Further studies with long-term radiologic evaluations are needed.

RESUMO

BACKGROUND: Prostate cancer (CaP) in India is the 10th most common malignancy affecting men. CaP incidence in India is low, but rising like other countries. The reasons for this racial disparity are uncertain. The foremost reasons that may underlie regional/ethnic differences are genetic polymorphisms, altered hormonal status, socioeconomic status, and obesity. This study aimed at investigating the role of adipocytokines in stimulating the promotion and progression of CaP. METHODS: A cross-sectional study on histopathologically proven prostate cancer (N=95) and benign prostatic hyperplasia (N=95) patients was undertaken. CaP patients were classified into high-grade (N=62) and low-grade (N=33), and high stage (N=31) and low stage (N=64) groups. The level of body mass index (BMI), waste to hip ratio (WHR), interleukin-6 (IL-6), leptin, and adiponectin were compared between BPH and CaP groups and between grades and stages of prostate cancer. RESULTS: The level of BMI was significantly (p<0.001) higher in CaP patients (26.58±4.76) in comparison to BPH (22.15±2.90). Similarly, WHR was significantly (p<0.0001) higher in the CaP patients (1.08±0.37) in comparison to BPH (0.86±0.15). Leptin (BPH: 25.60, CaP: 56.00) and II-6 levels (BPH: 9.90, CaP: 32.30) were significantly higher, but adiponectin was significantly lower in CaP patients as compared to BPH. High grade CaP patients had significantly higher BMI and WHR in comparison to low grade, and WHR was also higher in high stage CaP. Leptin and IL-6 level were higher in high stage and high grade, but adiponectin was low in high stage and high grade groups in comparison to low stage and low grade groups. CONCLUSIONS: Higher BMI and WHR correlate with prostate cancer independently, suggesting obesity to be a promoter of poor prostate health. Leptin and IL-6 appear to have stimulating effect on prostate cancer cells inducing the promotion and progression of CaP, but adiponectin appears to be protective against prostate cancer.

RESUMO

PURPOSE: To assess correlation between lactate levels in vaginal fluid and onset of labor in suspected PROM. METHOD: A prospective observational study conducted at the Dept. of Obstetrics and Gynecology and Pathology from 2008 to 2009. 118 women with complaints of leaking per vaginum underwent a sterile speculum examination and vaginal fluid was taken to estimate lactate level. Then, women were followed till the spontaneous onset of labor. The association was presented as Odds ratio with 95 %CI. RESULTS: The median time of onset of spontaneous labor and examination was 12 h in patients with lactate levels >5.0 mmol/L and 76 h in patients with lactate levels <5.0 mmol/L. Among 62 women with lactate levels >5.0 mmol/L, 67.7 % of women (n = 42) had spontaneous onset of labor within 24 h and 83.87 % women of (n = 52) within 48 h. CONCLUSION: A lactate level >5.0 mmol/L is significantly associated with the spontaneous onset of labor within 24 and 48 h in suspected cases of PROM.

RESUMO

Diabetic patients are often at a higher risk for developing several types of infections and infection does alter the handling of glucose by tissues. Pulmonary infections in diabetics are characterised by alteration in host defence, in entire body and in the lung locally as well as in the function of respiratory epithelium and ciliary motility. Association between diabetes mellitus and pulmonary tuberculosis is well established, while the prevalence of tuberculosis is increased 4-5 times more among diabetics. Impairment of host defence plays an important role for changing the clinical, radiological and bacteriological presentation in diabetic patients. It is also reported by the various studies that hyperglycaemia favours the growth of tuberculosis bacilli. So the severity of tuberculosis appears more cirtical with the degree of hyperglycaemia and host defence activity. This overlap between the diabetic and tuberculosis epidemics could adversely affect global tuberculosis control efforts.

RESUMO

BACKGROUND: Tumour necrosis factor alpha is a multifunctional proinflammatory cytokine involved in the pathogenesis of metabolic syndrome, insulin resistance, and obesity. Aim of this study is to investigate in a North Indian female population the impact of the G-308A TNF-α variant on various components of the metabolic syndrome, Insulin Resistance, serum TNF-α and Leptin levels. METHODS: The G-308A TNF-α polymorphism has been studied in 269 females with metabolic syndrome (NCEP ATP III criteria) (age 31.91±6.05) and 272 healthy females without metabolic syndrome (age 30.96±7.01). The G-308A variant was detected by PCR amplification and Nco-1 digestion. RESULTS: Homozygous mutant genotype (AA) (p=<0.001: OR=3.24: 95% CI=2.15-4.89) and mutant allele (A) (p=<0.001: OR=3.04: 95% CI=2.08-4.43) of TNF-α was significantly less frequently observed in the control population as compared to study group. Furthermore, on dividing the subjects into two groups according to the absence (TNF-1 allele) or presence of the mutant A (TNF-2) allele, significant results were obtained in most of the metabolic risk factors. CONCLUSIONS: Our results suggest that the G-308A polymorphism of the TNF-α gene may be independently associated with hypertension, leptin level and hypercholesterolemia leading to metabolic syndrome independent of Insulin resistance and hyperglycemia.

RESUMO

BACKGROUND: Obesity is a very common disorder directly linked with various diseases such as type-2 diabetes, hypertension and atherosclerosis. Variants in the FTO gene have been associated with Body Mass Index in Western European and North American populations. AIM: This study analysed the association between the FTO gene variant rs17817449 (G>T) and obesity and obesity-related phenotypes in a north Indian population. SUBJECTS AND METHODS: A total of 642 subjects, 309 obese and 333 non-obese individuals, were included in this case-control study. Genotyping of FTO gene (rs17817449) polymorphism for all subjects was performed by the PCR-RFLP method. RESULTS: Significant associations were found for FTO rs17817449 SNP with obesity and obesity-related phenotypes. The strongest associations were observed between the rs17817449 and fasting blood glucose, insulin, homeostasis model of assessment--insulin resistance (HOMA-IR) and fat mass under a recessive model. CONCLUSIONS: This study replicated the genetic association of SNP of FTO (rs17817449) with obesity in a north Indian population and, to the authors' knowledge; this is the first such association study in a north Indian population. This study also established that SNP in intron 1 of FTO (rs17817449) are strongly associated with several measures of adiposity and are also associated with plasma insulin, insulin resistance, percentage body fat and fat mass.

RESUMO

BACKGROUND: Hepsin (HPN), a type II trans-membrane serine protease, has been reported to be one of the most up regulated genes in prostate cancer. The aim of the present study was to find out immuno-histochemistry based phenotypic expression of HPN in formalin fixed paraffin embedded sections of prostate cancer compared with that in benign prostatic hyperplasia, in a prospective clinical setting, to know the differential status of HPN expression in benign and malignant prostatic disease. MATERIALS AND METHODS: Tissue biopsies of histologically proven cases of prostatic cancers (48), benign prostatic hyperplasia (42), benign prostatic hyperplasia with prostatic intraepithelial neoplasia (7) and 4 cases of benign prostatic hyperplasia with prostatitis, were subjected to immunohistochemical staining with HPN antibody by strepavidin biotin method. RESULTS: Hepsin expression was 100% in prostate carcinoma, 11.9% (5/42) in benign prostatic hyperplasia, 57.14% (4/7) in benign prostatic hyperplasia with prostatic intraepithelial neoplasia (PIN), and none in benign prostatic hyperplasia with prostatitis. Hepsin staining showed higher expression in high grade tumor in comparison to low grade tumor. CONCLUSIONS: Positive immunohistochemical expression of hepsin in cent percent cases of prostate cancer cases is intriguing, underscoring the significance of hepsin gene expression in prostate cancer.

RESUMO

OBJECTIVES: To observe the effect of regular yogic practices and self-discipline in reducing body fat and elevated lipids in CAD patients. METHOD: In this study one hundred seventy (170) subjects, of both sexes having coronary artery disease were randomly selected form Department of Cardiology. Subjects were divided in to two groups randomly in yoga group and in non-yoga group, eighty five (85) in each group. Out of these (170 subjects), one hundred fifty four (154) completed the study protocol. TIME LINE: The yogic intervention consisted of 35-40 min/day, five days in a week till six months in the Department of Physiology CSMMU UP Lucknow. Body fat testing and estimation of lipid profile were done of the both groups at zero time and after six months of yogic intervention in yoga group and without yogic intervention in non yoga group. RESULTS: In present study, BMI (p<0.04), fat % (p<0.0002), fat free mass (p<0.04), SBP (p<0.002), DBP (p<0.009), heart rate (p<0.0001), total cholesterol (p<0.0001), triglycerides (p<0.0001), HDL (p<0.0001) and low density lipoprotein (p<0.04) were changed significantly. CONCLUSION: Reduction of SBP, DBP, heart rate, body fat%, total cholesterol, triglycerides and LDL after regular yogic practices is beneficial for cardiac and hypertensive patients. Therefore yogic practices included in this study are helpful for the patients of coronary artery disease.

RESUMO

OBJECTIVES: External root resorption is the complication of intra-coronal bleaching done with 30% H2O2 alone or mixed with sodium perborate but not with sodium perborate mixed with water. The study was done to comparatively evaluate the H2O2 leakage from three H2O2 liberating bleaching agents. STUDY DESIGN: Fifty one single rooted human teeth were used. After root canal therapy gutta percha was removed below cemento-enamel junction. Three bleaching agents: sodium perborate mixed with water, sodium perborate mixed with 30% H2O2 and 30% H2O2 alone were used. Teeth without defect, with cervical root defect and with mid root defect constituted group A, group B and group C. According to various bleaching agents groups were subdivided into subgroup 1, 2 and 3. H2O2 leakage was measured with the help of spectrophotometer RESULTS: Almost all teeth showed H2O2 leakage. It was maximum in B1 followed by C1, B2, A1, A2, C2, B3, A3 and C3. CONCLUSION: Sodium perborate mixed with water was found to be the best bleaching agent.

RESUMO

To evaluate effectiveness of 200 mg elemental iron once per week for prophylaxis in non-anaemic pregnant women, a prospective longitudinal study with observational design was carried out at a tertiary care teaching hospital. Fifty pregnant women received daily (group 1) and 50 pregnant women received weekly (group II) oral therapy (100 mg elemental iron, 1.5 mg folic acid and 15 microg of vitamin B12). Haemoglobin, PCV estimation were carried out during follow-up periods at 4, 8 and 14 weeks. Iron profile (serum iron, TIBC, serum ferritin) estimation was done before and after 14 weeks of iron supplementation. Haemoglobin, PCV and serum iron increased significantly in both the groups (p < 0.001) but on intergroup comparison it was significantly higher in group I than group II (p < 0.001). Serum ferritin improved in both the groups but improvement was not significant in weekly supplemented group. Compliance was better and side-effects were less in group II as compared to group I (11.36% versus 39.9%) The supplementation of pregnant women once per week with 200 mg of elemental iron is an effective option for prophylaxis in mild anaemic or non-anaemic pregnant women.

RESUMO

The present investigations were aimed to identify the possible association between genetic polymorphism in interleukin-6 (IL-6) G-174C gene, which confers susceptibility to metabolic syndrome, and serum level of resistin in North Indian women. The study population comprised 370 unrelated Indian women (192 having abdominal obesity and 178 controls). Polymorphism in genotype (CC+GC) of IL-6 G-174C gene was determined using a combination of polymerase chain reaction (PCR) and sequence-specific primer with restriction fragment length polymorphism (RFLP) technology. Insulin resistance (IR) and serum resistin level were also analyzed along with metabolic risk factors. Of 192 abdominal obese women, 147 (76.56%) were found to have mutant CC+GC (p = 0.001) genotype and allele frequency (p = 0.001), which was significantly higher 45 (23.44%) than non-obese and their respective wild type. The mutant genotype (CC+GC) of IL-6 gene was found to be associated significantly with high triglyceride (p = 0.025) and resistin level (p < 0.001), when compared with respective wild genotype (GG) in obese women. Non-obese women with no signs of metabolic risk factors were found to have significantly low level of serum resistin and IR in comparison to obese women having genetic polymorphism for IL-6 G-174C gene. Study suggests that IL-6 G-174C gene is one among the susceptibility loci for metabolic syndrome in North Indian women. Genotype for this polymorphism may prove informative for prediction of genetic risk for metabolic syndrome. Further, high level of serum resistin molecules may be targeted to correlate with metabolic syndrome risk factors and could be used as early prediction marker.
