The frequency, related cause of disease, and treatment of hepatitis B virus infection: A systematic review and meta-analysis in Iran.

Background: Hepatitis B virus (HBV) is one of the most dreadful viruses causing high mortality rates and serious damages to hepatocytes. The aim of this study was to assess the frequency, related causes/risk factors, and treatments of HBV infection in Iran by systematic review and meta-analysis. Materials and Methods: The data were obtained by a literature search in the PubMed, Scopus, SID, and Web of Sciences databases. Keywords included prevalence, risk factors, causes, treatment, and HBV. The Persian equivalents of these keywords were also searched. The time span included 2004 to2021. The Q and I 2 statistics were used to check heterogeneity among studies. The data were analyzed using Stata (version 14). Results: The frequencies of HBV infection and its pharmaceutical therapy were P = 6% (95% confidence interval [CI]: 4-9, I 2 = 95.2%, P < 0.001) and 19% (95% CI: 18%-30%, I 2 = 98.9%, P < 0.001), respectively. The most common risk factors/causes of HBV were narcotic consumption, blood-related factors, and transmission from infected individuals with the respective frequencies of 27% (95% CI: 16%-38%, I 2 = 88.7%, P < 0.001), 32% (95% CI: 11%-53%, I 2 = 99.8%, P < 0.001), 25% (95% CI: 10%-41%, I 2 = 99.3%, P < 0.001), and 15% (95% CI: 7%-22%, I 2 = 98.4%, P < 0.001), respectively. Conclusion: The most important causes of HBV infection were transmission from infected people, narcotic consumption, and blood-related factors. The main therapeutic intervention for HBV was pharmaceutical therapy.

Comparison between the two drug regimens of PPI+Amoxicillin+ Rifampicin and PPI+Amoxicillin+ Levofloxacin for the treatment of H. pylori infections resistant to the first line drug regimen among patients referred to Ilam clinics.

AIM: This study compares the effects of two drug regimens for Helicobacter pylori (H. pylori) infection resistant to the first line drug regimen among patients referred to Ilam clinics, Iran. BACKGROUND: Single drug regimen is not effective for H. pylori infection and therefore, application of triple or quadruple drug regimens are currently applied. METHODS: This study was performed by a before-after comparative method and patients were randomly selected among those consecutively referred to Ilam gastrointestinal clinics. Patients with failure in the first line treatment, were randomly divided into two equal groups and each group was treated by one of the PPI+Amoxicillin+Rifampicin or PPI+Amoxicillin+Levofloxacin drug regimens for 14 days. Six weeks after treatment, patients were tested for H. pylori stool antigen and the results were compared between two groups. RESULTS: In this study, 100 patients including 49 (49%) men and 51 (51%) women were examined. There was no statistical difference between the two groups for gender, age and living location at the start of study (p = 0.068). The mean age of the patients was 44.55 ±15.1 years old ranging from 17 to 85 years. Response to treatment among the levofloxacin group, was 90% and in rifampicin group 72% with a significant difference (p<0.04). CONCLUSION: The response rate of H. pylori infection to the Levofloxacin based regimen was 90%; however, the application of rifampicin in combination with other drugs against H. pylori infection (72% response rate), should be limited to reduce the possibility of drug resistance in case of tuberculosis infection.

Celiac disease in Iranian irritable bowel syndrome patients; a systematic review and meta-analysis.

AIM: The present study was conducted to evaluate the prevalence, clinical symptoms and pathological findings of celiac disease (CD) in irritable bowel syndrome (IBS) patients in Iran. BACKGROUND: Several studies show high prevalence of CD in IBS patients, but the results are contradictory. METHODS: The present study was conducted based on MOOSE protocol and results were reported according to PRISMA guideline. The search was done using international online databases (Scopus, PubMed, Science Direct, Cochrane Library, Embase, and Web of Science), national databases and Google Scholar search engine. RESULTS: The pooled prevalence of CD in 2,367 Iranian IBS patients was estimated to be 6.13% (95%CI: 4.11-9.05). The prevalence of CD in men and women with IBS was 4.28% (95% CI: 2.45-7.37) and 7.19% (95% CI: 4.51-11.28), respectively. The serological prevalence of anti tTG-IgA (11 studies with 2901 IBS patients) and AGA-IgG (4 studies with 936 IBS patients) was estimated to be 5.35% (95%CI: 3.60-7.89) and 6.35% (95%CI: 2.05-18.03), respectively. The clinical symptoms of CD among IBS patients included predominant diarrhea (47.87% [95%CI: 22.46-74.43]), predominant constipation (17.34% [95%CI: 9.17-30.35]), and alternative diarrhea and constipation (27.84% [95%CI: 11.57-53.23]). According to pathological findings based on marsh classification, the prevalence of CD at stages 1, 2 and 3 were 30.89% (95%CI: 13.25-56.68), 36.56% (95%CI: 21.74-54.45) and 52.87% (95%CI: 14.48-88.13), respectively. CONCLUSION: In the present meta-analysis, we observed a high prevalence for CD among Iranian IBS patients, which is higher than global estimates. Examination of all IBS patients in terms of CD seems to be necessary, but cost-effectiveness should be considered.

Prevalence of peptic ulcer in Iran: Systematic review and meta-analysis methods.

BACKGROUND: Peptic ulcer is a prevalent problem and symptoms include epigastria pain and heartburn. This study aimed at investigating the prevalence and causes of peptic ulcers in Iran using systematic review and meta-analysis. MATERIALS AND METHODS: Eleven Iranian papers published from 2002 to 2016 are selected using valid keywords in the SID, Goggle scholar, PubMed and Elsevier databases. Results of studies pooled using random effects model in meta-analysis. The heterogeneity of the sample was checked using Q test and I2 index. RESULTS: Total sample size in this study consist of 1335 individuals with peptic ulcer (121 samples per article). The prevalence of peptic ulcers was estimated 34% (95% CI= 0.25 - 0.43). The prevalence of peptic ulcers was 30% and 60% in woman and man respectively. The highest environmental factor (cigarette) has been addressed in 30% (95% CI= 0.23-0.37) of patients. The prevalence of Helicobacter pylori was estimated in 62% (95% CI= 0.49-0.75) of patients. CONCLUSION: The results of this study show that prevalence of peptic ulcers in Iran (34%) is higher that worldwide rate (6% to 15%). There was an increasing trend in the prevalence of peptic ulcer over a decade from 2002 to 2016.

Epidemiology of hepatitis B in pregnant Iranian women: a systematic review and meta-analysis.

Perinatal transmission is one of the most common routes of hepatitis B virus (HBV) transmission. This study aims to identify the epidemiological features of HBV among pregnant Iranian women. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Two authors independently searched several online databases without time limit until May 2017. The databases include Magiran, Iranmedex, SID, Medlib, IranDoc, Scopus, PubMed, Science Direct, Cochrane, Web of Science and Google Scholar. The data were analyzed based on a random-effects model using Comprehensive Meta-Analysis software version 2. Thirty-seven studies were included in the meta-analysis. The prevalence of HBV among pregnant Iranian women was 1.18% (95% CI: 0.09%-1.53%). The prevalence of HBV among pregnant women living in urban and rural areas was 1.60% (95% CI: 0.06%-4.30%) and 1.70% (95% CI: 0.09%-3.2%), respectively. The prevalence of HBV among housewives and working pregnant women was 4.3% (95% CI: 1.4%-12.5%) and 1.2% (95% CI: 0.02%-5.8%), respectively. The risk of developing an HBV infection was significantly associated with illiteracy (p = 0.013), abortion (p = 0.001), blood transfusion (p < 0.001) and addicted spouse (p = 0.045). However, no significant relationship was observed between HBV infection and urbanization (p = 0.65), occupation (p = 0.37), history of surgery (p = 0.32) or tattooing (p = 0.69). Vaccination coverage (receiving at least a single dose) in pregnant women was 9.8% (95% CI: 5.3%-17.5%). The prevalence of HBV among pregnant women is lower than in the general population of Iran. HBV vaccination coverage was low among pregnant Iranian women. Therefore, health policy-makers are recommended to enforce immunization programs for HBV vaccination among high-risk pregnant women.

A self-assessment predictive model for type 2 diabetes or impaired fasting glycaemia derived from a population-based survey.

AIMS: There is no cure for diabetes and its prevention is interesting for both people and health policy makers. The aim of this study was to construct a simple scoring system to predict diabetes and suggest a self assessment predictive model for type 2 diabetes in Iran. METHODS: This study was a part of a comprehensive population based survey performed in Ilam province during 2011-2012, including 2158 cases≥25years. All demographic and laboratory results were entered into the prepared sheets and were analysed using SPSS 16. By identification of relative risks of diabetes and IFG, a predictive model was constructed and proposed for these abnormalities. RESULTS: Totally, 2158 people comprising 72% female, 60% from urban regions, mean age of 45.5±14years were investigated and the average height, weight, FBS and waist of participants were as follows respectively: 164±8.9cm, 68.4±12.3kg, 5.7±2.8mmol/l (102.6±49.9mg/dl) and 82.3±14.3cm. The prevalence of IFG, diabetes and hyperglycaemia among all participants were 7.8%, 11.8% and 19.6% respectively. Regression analysis revealed familial history of diabetes, place of life, age, hypertension, daily exercise, marital status, gender, waist size, smoking, and BMI as the most relevant risk factors for diabetes and hyperglycemia. CONCLUSION: A self-assessment predictive model was constructed for general population living in the west of Iran. This is the first self-assessment predictive model for diabetes in Iran.

The Effects of Creatine Monohydrate on Permeability of Coronary Artery Endothelium and Level of Blood Lipoprotein in Diabetic Rats.

BACKGROUND: Creatine monohydrate has beneficial effects on serum glucose. This study aimed to investigate the effects of creatine on serum biochemical markers and permeability of coronary arteries among diabetic rats. MATERIAL AND METHODS: 32 Wistar rats, which weighed 150-200 grams were randomly divided into 4 groups including: group I, control; group II, creatine monohydrate; group III, diabetic rats; and group IV, diabetic rats + creatine. Creatine monohydrate was applied by 400 mg/kg/daily for 5 months. Animals' weights and blood samples were taken before and after the study. Endothelial permeability rate was measured by Evans Blue method. Data were analysed by SPSS 16. RESULTS: At the end of fifth month, rats' weights in diabetic group under treatment with creatine, compared to those without, increased significantly (p<0.0001). Also, the serum levels of triglyceride (TG), cholesterol, glucose and low density lipoprotein (LDL)- cholesterol decreased significantly among those under treatment with creatine (p<0.05), but high density lipoprotein (HDL)- cholesterol increased significantly (p<0.002). Permeability rate of coronary arteries was reduced significantly in the diabetic group treated by creatine compared to untreated groups, closed to the intact group (p<0.001). CONCLUSION: Results of this study showed that creatine monohydrate caused an improvement of serum biochemical markers associated with diabetes and reduced the permeability rate of coronary arteries among diabetic rats.

Epidemiological survey of intentional poisoning suicide during 1993-2013 in Ilam Province, Iran.

BACKGROUND: Suicide is an important social tragic phenomenon which occurs by different tools or methods in different communities. Considering deliberate poisoning as a common and important method in Ilam province for suicide, the present study was launched to epidemiologically assess committing suicide in Ilam province, Iran, based on intentional poisoning. METHODS: By a retrospective study, all the recorded data associated with intentional poisoning suicide in Ilam Province during 1993-2013 were analyzed. All the demographic variables and the suicides' outcomes were analyzed using the Chi-Square test, and the univariate and multivariate logistic regression models. RESULTS: Totally, 6794 cases of suicide (annual incidence rate of 87.28/ 100, 000) associated with poisoning were evaluated. The incidence rate of suicide attempts was 84.63/ 100, 000 (94.51 in female and 74.98 in male) and the incidence rate of completed suicide was 2.17/ 100, 000 (1.94 in female and 2.40 in male). Also, the highest rates of attempted and completed suicide (annual incidence rate of 172.42 and 4.14, respectively) were attributed to the age group of 15-24 year. CONCLUSION: Females had a greater tendency to commit suicide by poisoning, and the lower level of education, the age group of 15-24 years and single individuals were more associated with suicide using poisonings. The incidence of attempted suicide in females and completed suicide in males was higher in this method. Considering the high rate of suicide by poisoning, further attention and supervision on the sale and reserve of drugs and poisons is necessary. Meanwhile, it seems that due to momentary emotions during the pubertal stage, the risk of committing suicide is increased especially among unemployed individuals; therefore, performing an extensive psychotherapy intervention is needed in the societies with younger populations.

Therapeutic effects of Citrullus colocynthis fruit in patients with type II diabetes: A clinical trial study.

AIM: Citrullus colocynthis plant was traditionally used for the treatment of diabetes in Sabzevar city, Iran. This study aimed to investigate the effects of C. colocythis on fasting blood sugar (FBS) and HbA1c in patients with type II diabetes. MATERIALS AND METHODS: Totally 70 patients with type II diabetes attending the diabetes clinic in Sabzevar city were investigated. Patients were divided into two groups of intervention and placebo randomly and were studied for 2 months. Mean serum level of FBS and HbA1c was compared within and between groups at the end of the study. Data were analyzed using student and paired t-tests via SPSS software version 16. RESULTS: A significant difference was revealed between before and after intervention for HbA1c and FBS levels in the intervention group (P = 0.01 and P = 0.04, respectively). The difference between before and after intervention for FBS and HbA1c levels in the placebo group were not significant (P = 0.8, P = 0.68 respectively). This study showed a negative relationship between either the mean ± standard deviation serum level of FBS or HbA1c and body mass index in the treatment group significantly (P = 0.03, 0.008, respectively). The present study did not identify any side effects during the study period among the treatment group. CONCLUSION: According to the findings of this study, application of 125 mg C. colocynthis once per day for 2 months can lead to considerable decrease in the mean levels of HbA1c and FBS among the patients with type II diabetes without any side effects.

Contribution of Blastocystishominis subtypes and associated inflammatory factors in development of irritable bowel syndrome.

Blastocystis hominis with worldwide distribution is a human intestinal protozoa found in all countries. There have been differences in the severity of the pathogenesis of various Blastocystis spp. and a concomitant variation in the plasma concentration of the cytokines in patients with irritable bowel syndrome. In the present study, we aimed to demonstrate the contribution of B. hominis subtypes in the development of irritable bowel syndrome. Stool samples were collected from patients with gastrointestinal disorders. All samples were evaluated through native-lugol method. Total DNA was extracted. A PCR protocol was developed to amplify a specific region of the SSU ribosomal DNA (rDNA) gene. Serum levels of IL-6 and TNF-α were determined by immunoassay methods. The ClustalW algorithm was applied to align and blast the nucleotide sequences of the amplified region of the SSU rDNA gene. To evaluate the phylogenetic and molecular evolutionary of the nucleotide sequences, we used the MEGA software. In this study, we found 26 haplotypes of B. hominis in the studied samples which were collectively belong to five subtypes (ST1, ST2 in patients without irritable bowel syndrome vs. ST3 and two unknown subtypes in patients with irritable bowel syndrome). Result of ELISA showed a high level of IL-6 and TNF-α in the serum of patients with irritable bowel syndrome. The genetic heterogeneity of B. hominis and the existence of different subtypes of the protozoan in patients with IBS may shed light to the fact that some subtypes of parasites may involve in the pathogenesis of IBS.

Association between serum levels of high sensitive C-reactive protein and inflammation activity in chronic gastritis patients.

BACKGROUND: Gastritis is an important premalignant lesion and recent studies suggested a production of inflammatory cytokine-like C-reactive protein during gastritis. This study aimed to determine any relationship between high sensitive C-reactive protein (hs-CRP) and inflammation activity among patients with gastritis. METHODS: Demographic and clinical variables of participants were collected by a validated questionnaire. Using histology of the gastric mucosa, Helicobacter pylori status was investigated and serum concentrations of hs-CRP were measured among dyspeptic patients. Correlation between hs-CRP serum levels and inflammation activities was evaluated by logistic regression analysis. The relation between active inflammation and other variables was evaluated by logic link function model. RESULTS: Totally 239 patients (56.6% female) were analysed. The prevalence of mild, moderate and severe inflammation activities was 66.5%, 23.8% and 9.6% respectively. Mean ± SD of hs-CRP among men and women were 2.85 ± 2.84 mg/dl and 2.80 ± 4.80 mg/dl (p = 0.047) respectively. Mean ± SD of hs-CRP among patients with H. pylori infection, gland atrophy, metaplasia and dysplasia were 2.83 ± 3.80 mg/dl, 3.52 ± 5.1 mg/dl, 2.22 ± 2.3 mg/dl and 5.3 ± 5.04 mg/dl respectively. Relationship between hs-CRP and inflammation activities (p < 0.01) was significant. A significant relationship between dysplasia and hs-CRP (p < 0.04) was revealed. A significant relationship between age and hs-CRP was detected (p < 0.05). CONCLUSION: Although serum hs-CRP is not a specific biomarker for gastritis, elevated hs-CRP levels may be considered as a predictive marker of changes in gastric mucosa and a promising therapeutic target for patients with gastritis.

Precancerous histopathologic lesions of upper gastrointestinal tract among dyspeptic patients upon endoscopic evaluations.

PURPOSE: Gastric cancer is one of the most important causes of morbidity and mortality worldwide which is influenced by different risk factors. This study aimed to investigate the effects of various factors associated with precancerous lesions among dyspeptic patients. METHODS: Among dyspeptic patients admitted to gastrointestinal clinics in Ilam city, west of Iran, 1123 were investigated during 2008 to 2011. All patients were evaluated by endoscopy and their biopsy samples were examined for histological differentiations and their pathology reports were classified according to Sydney criteria. RESULTS: One thousand out of 1123 admitted dyspeptic patients were finally analyzed. The mean age of participants was 48 years (ranged 21-84 years), and 64.8% of patients were male. The frequency of patients with atrophy, metaplasia, or both was 14.4%, adenocarcinoma 1.2%, and polyp hyperplasia 0.7%, respectively. The highest frequency was related to those with chronic gastritis accompanied by Helicobacter pylori infection with a figure of 80.8%. The frequency of precancerous lesions among smokers compared to non-smokers was higher significantly (p < 0.03). Though non-significant, BMI was associated with the higher risk of premalignant lesions among dyspeptic patients by an increasing manner. CONCLUSION: Chronic gastritis accompanied with H. pylori infection was revealed as the most prevalent variable among dyspeptic patients. Also, higher BMI compared to normal and smokers compared to non-smokers were more involved by precancerous lesions.

Hyperglycaemia and its related risk factors in Ilam province, west of Iran- a population-based study.

BACKGROUND: Impaired fasting glycaemia (IFG) has been defined as the fasting plasma glucose level between 6.1 (110 mgl/dl) and 6.9 mmol/l (125 mgl/dl). Control of hyperglycaemia during acute illness among diabetic and non-diabetic patients has been associated with improved outcome. The aim of this study was to investigate the prevalence of and factors related to hyperglycaemia, IFG and diabetes in west of Iran. METHODS: This project was performed by a cross-sectional method in Ilam province including 2158 people ≥ 25 years old. From the list of all rural and urban health centers of each county, several were randomly selected. For each selected health centre, families numbered 1-20 completed questionnaire forms for all the members aging ≥ 25 years. FBS was measured for all the participants by standard method. All the demographic and laboratory results were analysed using SPSS 16. Descriptive and regression analysis were used for statistical analysis appropriately. RESULTS: A total of 2158 people were evaluated in this study, among which 72 % were female with a mean age of 45.5 ± 14 years. 40 % of participants were from urban regions and the mean height, weight, FBS and waist size of the participants were respectively as follows: 164 ± 8.9 cm, 68.4 ± 12.3 kg, 5.7 ± 2.8 mmol/l (102.6 ± 49.9 mg/dl) and 82.3 ± 14.3 cm. The prevalence of IFG, diabetes and hyperglycaemia among participants were 7.8 %, 11.8 % and 19.6 %, respectively and participants from urban area showed a significantly higher prevalence of hyperglycaemia compared to rural regions (P < 0.0001). CONCLUSION: The most effective factors associated with IFG and diabetes were family history of diabetes, age, hypertension, marital status, place of life and smoking, respectively. The prevalence of IFG, diabetes and hyperglycemia among the population living in Ilam province, west of Iran, were 7.8, 11.8 and 19.6 % respectively which were directly increased with age.

Application of Lidocaine Spray for Tracheal Intubation in Neonates - A Clinical Trial Study.

BACKGROUND: Tracheal intubation is extremely distressing, painful, and may influence heart rate and blood pressure. Sedatives, analgesics, and muscle relaxants are not commonly used for intubation in neonates. OBJECTIVES: This study aimed to evaluate the effects of lidocaine spray as a non-intravenous drug before neonatal intubation on blood pressure, heart rate, oxygen saturation and time of intubation. PATIENTS AND METHODS: In a randomized, controlled study each neonate was randomly assigned to one of the two study groups by staffs who were not involved in the infant's care. The allocation concealment was kept in an opaque sealed envelope, and the investigators, the patient care team, and the assessors were blinded to the treatment allocation. The selected setting was NICU unit of a teaching hospital in Ilam city, Iran and participants were 60 neonates with indication of tracheal intubation with gestational age > 30 weeks. Patients in the treatment group received lidocaine spray and the placebo group received spray of normal saline prior to intubation. Main outcome measurements were the mean rates of blood pressure, heart rate, oxygen saturation, intubation time and lidocaine side effects were measured before and after intubation. RESULTS: Totally 60 newborns including 31 boys and 29 girls were entered into the study (drug group n = 30; placebo group n = 30). Boy/girl ratio in treatment and placebo groups were 1.3 and 0.88, respectively. Mean age ± SD of participants was 34.1 ± 24.8 hours (treatment: 35.3 ± 25.7; placebo: 32.9 ± 24.3; P < 0.0001). Mean weight ± SD of neonates was 2012.5 ± 969 g. Application of lidocaine spray caused a significant reduction of mean intubation time among treatment group compared with placebo group (treatment: 15.03 ± 2.2 seconds; placebo: 18.3 ± 2.3 seconds; P < 0.0001). Mean blood pressure, heart rate and oxygen saturation rate, among neonates in treatment group was reduced after intubation compared with their relevant figures before intubation; however, their differences were not statistically significant except for mean oxygen saturation rate that was reduced significantly in placebo group. No side effects were observed during study. CONCLUSIONS: Though the current study revealed some promising results in the application of lidocaine spray during neonatal intubation without any considerable side effects; however, the current investigation could only be considered as a pilot study for further attempts in different locations with higher sample sizes and in different situations.

Coenzyme Q10 in combination with triple therapy regimens ameliorates oxidative stress and lipid peroxidation in chronic gastritis associated with H. pylori infection.

Chronic gastritis associated with H. pylori infection causes oxidative stress in the stomach. This study aimed to evaluate the therapeutic effects of coenzyme q10 among gastric patients infected by H. pylori. By a clinical trial, chronic gastric patients infected by H. pylori were randomly divided into 2 groups: intervention and placebo. The placebo group received a standard triple therapy regimen, and the intervention group received the triple regimen + coenzyme Q10 (CoQ10). Mean inflammation score; serum levels of 3 serum markers were then compared. A total of 100 participants of whom 67% were female were evaluated. The mean age of participants was 59.4 ± 11.4 years. The mean inflammation score was considerably decreased at the end of the study, in the intervention group. The mean levels of total antioxidant capacity (TAC) and glutathione peroxidase (GPx) at the end of the study were reduced among the triple therapy group (P < .05, P =.03 respectively). The mean levels of TAC and GPx were significantly higher among the intervention group at the end of the study compared with those at the start of the study. The combination of triple therapy with CoQ10 demonstrated an effective outcome on the mucosal inflammation, and stress oxidative in patients with chronic gastritis.

Correlation of Body Mass Index and Serum Parameters With Ultrasonographic Grade of Fatty Change in Non-alcoholic Fatty Liver Disease.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a common liver disease in the western population and expanding disease in the world. Pathological changes in fatty liver are like alcohol liver damage, which can lead to end-stage liver disease. The prevalence of NAFLD in obese or overweight people is higher than general population, and it seems that people with high Body Mass Index (BMI) or abnormality in some laboratory tests are more susceptible for severe fatty liver and high grade of NAFLD in ultrasonography (U.S). OBJECTIVES: This study aimed to evaluate the correlation of BMI and laboratory tests with NAFLD in ultrasonography. MATERIALS AND METHODS: During a multi-step process, we selected two-hundred and thirteen cases from four hundred and eighteen patients with NAFLD. Laboratory tests performed included: ALT, AST, FBS, Triglyceride and cholesterol levels, hepatitis B surface antigen, hepatitis C antibody, ceruloplasmin, serum iron, TIBC, transferrin saturation, ferritin, AMA, ANA, ANTI LKM1, serum protein electrophoresis, TSH, anti TTG (IgA). BMI and ultrasonography for 213 patients were performed, and then data was analyzed. These parameters and grades of ultrasonography were compared with the values obtained using one way ANOVA. An ordinal logistic regression model was used to estimate the probability of ultrasonography grade. The Statistical Package for the Social Science program (SPSS, version 16.0) was used for data analysis. RESULTS: Two-hundred and thirteen cases including 140 male and 73 female, were studied. In general, 72.3% of patients were overweight and obese. Post-hoc tests showed that only BMI (P < 0.001) and TG (P < 0.011) among variables had statistically significant associations with ultrasonography grade (USG), and ordinal logistic regression model showed that BMI and AST were the best predictors. DISCUSSION: Our results suggest that in patients with NAFLD, BMI and TG are most effective factors in severity of fatty liver disease and ultrasonography grade (USG). On the other hand, BMI as a predictor can be helpful. But, AST has not been a reliable finding, because it changes in many conditions.

Effects of Metoclopramide on Feeding Intolerance among Preterm Neonates; A Randomized Controlled Trial.

OBJECTIVE: To evaluate the efficacy and safety of metoclopramide in the treatment of feeding intolerance in preterm neonates less than 36 weeks of gestational age. METHODS: A randomized, controlled, masked cross-over study. A block of 4 randomizations was used. The "drug group" received intravenous metoclopramide before feeding and placebo group received placebo at the same time. The time to full enteral feeding and suspected adverse effects of metoclopramide, length of hospital stay or incidence of NEC or septicemia were the main outcome measures. FINDINGS: Mean (standard deviation) of weight and Apgar score among metoclopramide and placebo groups were 1638.3±321 gr, 8.9±1.4 and 1593.3±318.8 gr, 8.8±1.3 respectively. Times to full feeding were significantly shorter in the metoclopramide group than in the control group (12.9±5.6 vs 17.0±6.3; P<0.0001) and also the numbers of withheld feedings were significantly lower (P<0.0001). According to the regression analysis, lower weight and placebo group were significantly related to increasing of lavage frequency, number of vomits, start time of feeding, number of feeding cessations and decreased feeding completion time (P<0.0001).No adverse effects of this treatment modality were observed in the two groups. CONCLUSION: Intravenous metoclopramide may be considered as an attempt in facilitating and treatment of feeding intolerance in preterm neonates.

Serum gastrin 17, pepsinogen I and pepsinogen II in atrophic gastritis patients living in North-East of Iran.

BACKGROUND: Gastric carcinoma is the second most common cause of cancer-related death in Iran. It is well-known that atrophic gastritis is a major risk factor for gastric cancer, which leads to variations in the serum levels of gastrin 17 (G-17), pepsinogen I (P-I), and pepsinogen II (P-II). The aim of this study was to investigate the diagnostic accuracy of these serum biomarkers in the early detection of atrophic gastritis. MATERIALS AND METHODS: A total of 132 dyspeptic patients underwent upper endoscopy and biopsies were taken. The biopsy specimens were evaluated as the gold standard according to operative link for gastritis assessment staging system. Serum levels of G-17, P-I, and P-II were investigated using enzyme-linked immunosorbent assay. Receiver operating characteristic (ROC) analysis was used to calculate the diagnostic indices and optimal cut-off values using Statistical Package for the Social Sciences SPSS statistical software. RESULTS: A total of 67 men and 65 women were analyzed, among which 48 (36.4%) had atrophic gastritis. The mean age was 45.8 (±15.8) years. ROC curve analysis demonstrated that the biomarkers (including pepsinogen I/II [P-I/II] ratio), except for P-I, are diagnostically significant in detecting gastric atrophy. The area under the curve (95% confidence interval [CI]) for G-17, P-I, P-II, and P-I/II ratio were 0.65 (0.55-0.76), 0.42 (0.32-0.53), 0.62 (0.52-0.72), and 0.61 (0.50-0.72), respectively. However, the diagnostic indices were low (sensitivity <50%, specificity < 90%). The prevalence of Helicobacter pylori infection was significantly higher in patients with atrophy against those without atrophy (75.0% vs. 57.4%, P value < 0.0001). CONCLUSION: In the studied population, the serum biomarkers of atrophic gastritis are not useful screening tests due to their low sensitivity.
