Abstract:

Background: Helicobacter pylori (H. pylori) associated gastritis may cause iron deficiency anaemia. Therefore, this infection should be diagnosed and cured.

Aim: This study is aimed to find out association of H. pylori infection and iron deficiency anaemia.

Methods: Association of H. pylori infection and anaemia was studied in dyspeptic patients. Those who were found to be normal at upper GI endoscopy were included in this study. Rapid urease test was done to detect H. pylori infection. H. pylori positive patients were considered as group A and H. pylori negative as group B. A total of 194 patients (aged 18 to 60 years) of both sexes were included, 134 belonged to group A and 60 to group B. Five ml of blood was collected from each patients for estimation of hemoglobin level, serum ferritin, mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV). Iron deficiency anaemia was defined as hemoglobin(Hb) concentration <120 g/L in men and <110 g/L in women, serum ferritin <12 μg/L, mean corpuscular haemoglobin (MCH) <27 pg, and mean corpuscular volume (MCV) <80 fL. Iron deficiency was considered when serum ferritin was <12 μg/L (70).

Results & Conclusions: Serum ferritin was higher in H. pylori negative group than H. pylori positive group. In the multiple regression model H. pylori infection was associated with 28.8% decrease of serum ferritin (95% CI=-4.85 to-9.1); r2=0.271). The mean MCV was found to be 85.45±6.93 (in fL) in group A and 88.73±4.58 ( in fL) group B. The difference was statistically significant (p<0.05). The mean MCH was significantly lower in group A than group B. In male patients, the mean Hb% was lower than group B and the difference was statistically significant (p<0.05). In female patients mean Hb% of both groups were almost similar. So it appears that H. pylori infection is associated with iron deficiency anaemia.

Abstract:

In the study 63 H. pylori positive patients with peptic ulcer disease were randomized for eradication therapy for H. pylori for two weeks. Four regimens were used: ECA consisting of Esemoprazole (20 mg bid), Clarithromycin (500 mg bid) and Amoxicillin (1 gm bid), EAL- consisting of Esemoprazole (20mg bid), Amoxicillin (1gm bid), Levofloxaxin (500 mg once daily), EAT consisting of Esemoprazole (20mg bid), Amoxicillin (1gm bid), Tetracycline (500 mg bid) and ETL consisting of Esemoprazole (20 mg bid), Tetracycline (500mg bid) and Levofloxaxin (500 mg once daily). Out of 63 patients 13 dropped out. Six weeks after completion of therapy upper GI endoscopy was repeated to see endoscopic improvement and RUT (rapid urease test) was carried out. Conclusive result was obtained in 40 cases in RUT. Eradication therapy showed no statistically significant difference in different regimens
(p>0.05). Endoscopic improvement occurred in 33% to 71% patients in different regimens. Thirty six patients were found to be RUT negative and 4 were found to be RUT positive. Negativity rate ranged from 83% to 100% in different regimens. This result appears to be acceptable, good and even excellent with ETL.

Abstract:

The Diagnosis of inflammatory bowel disease (IBD) requires extensive and often invasive investigations including colonoscopy and histology and places a heavy burden, both on healthcare resources, because of the cost, and on the individual, in times of disease-related disability and poor quality of life. Recently, there has been increasing interest in noninvasive biomarkers to diagnose IBD and to monitor the disease activity. There is growing scientific interest in the investigation of volatile metabolites and numbers of studies have focused on the utilization of non-invasive biomarkers in the diagnosis of GI disease. The development of sophisticated analytical techniques has enabled the study and interpretation of changes in the faecal and breath volatile organic metabolites (VOMs) and its correlation with the pathophysiological mechanisms in IBD. VOMs are the chemicals that are the products and intermediates of metabolism and may be altered during the diseases process. Changes in the signature of VOMs could potentially provide diagnostic information about health and disease. Multiple studies have reported the differences in VOM profiles of healthy controls vs. patients with IBD other GI disorders. VOM profiles have been used to segregate patients by disease activity and the type of disease. The correlation of VOMs with Microbiota is interesting and supports the hypothesis of gut microbial dysbiosis in the etiology of IBD. This provides an important platform to explore the role of dysbiosis in IBD and other GI disorders pathogenesis and development of novel therapeutic targets. In future, further understanding of faecal VOMs may lead to the development of a rapid and simple point of care diagnosis and monitoring of IBD.

Abstract:

Westernized diet, defined by high contents of saturated fats and sucrose, is associated with the development of several diseases including metabolic syndrome, obesity and cancer. Intestinal inflammatory responses are mediated by a complex crosstalk between the environment, microbiota and the immune system. Alterations in any of these systems can lead to development of gastrointestinal conditions such as inflammatory bowel diseases (IBD). Triggering factors for IBD and colitis-associated cancer (CAC) include environmental factors (e.g. stress), gut microbiota composition and diet. Recent
reports indicate that a specific pathobiont outgrowth in IL-10-/- mice fed with a milk derived fat diet aggravated colitis. Epidemiological data have also identified processed meats and saturated fat as risk factors for IBD and colon cancer. Prebiotics are selectively fermentable ingredients that can change the composition and/or activity of the intestinal microbiota, which can lead to beneficial effects on the host. Short chain fatty acids (SCFAs) are the fermentation products of prebiotic digestion by the colonic commensal microbiota, with the most abundant SCFAs being butyrate, acetate and propionate. SCFAs, especially butyrate, act as source of energy for epithelial cells as well as being immune modulatory and helping dampening inflammation. In this talk, I’ll discuss our findings emanating from in vitro and in vivo studies investigating the effect of diets, bacteria and bacterial metabolites on intestinal epithelial cell responses and in experimental models of colitis and CAC. To date, we have data showing that high fat diets can positively and negatively affect the outcome of colitis and CAC by regulating the microbiota, microbial metabolites and host epithelial and immune responses. In addition, we have generated mechanistic insights on the role of individual SCFAs and IBD-associated pathobionts such as adherent and invasive Escherichia coli (AIEC) on intestinal epithelial cell responses.

Abstract:

Pilonidal sinus is a chronic inflammatory condition which is caused due to involution of hair fragment into the gluteal or natal region. It is also called as inflammatory disease of gluteal region. It is twice as common in males between 15-25 years of age. Occasionally it occurs in different region like umbilicus, nose, groin, axilla, clitoris, interdigital tract, suprapubic area, penis or occiput. The present report highlights the condition in a 24-year old male with discharging sinus in the gluteal cleft and itching from the past one-month. Diagnosis of the diseases is straightforward clinically with discharging sinus and multiple pits in the natal cleft, and choice of particular surgical approach was laser pilonidoplasty. The procedure was performed under local anaesthesia with 1470 nm diode laser as beam source, with radial fibre, which would destroy the deep fistula system of the sinus. A 600 micron fibre with a special glass top (CORONA) fistula probe fibre with power settings at 10 watt and energy dosage at 100 joules per cm was used. The patient recovered completely and returned to work within 2 months. The procedure does not involve any painful dressings post operatively. In our experience, laser pilonidoplasty is the choice of procedure for the disease as there are less chances of morbidity and recurrence and better chances of early healing and cure of the disease. Hair removal is maintained until wounds are healed, after which laser hair removal is recommended of the local area. The lasers thus, prove to be an attractive treatment alternate for pilonidal sinus.

Abstract:

Introduction: The most widely held hypothesis on the pathogenesis of IBD (Inflammatory Bowel Disease) is that overly aggressive acquired (T cell) immune responses to a subset of commensal enteric bacteria develop in genetically susceptible hosts, & environmental factors precipitate the onset or reactivation of disease. But it is almost universally accepted that a host genetic predisposition is critical for development of CD. Among bacteria Mycobacterium avium subsp paratuberculosis (MAP) has shown high prevalence although not uniformly. This large variation may be due to differences in DNA extraction techniques or to geographical variations in the prevalence and modes of transmission of MAP.

Aim & Objectives: This prospective study aimed to see the association of NTM with Crohn’s disease.

Methods: Patients of CD were included in the study as case. Patients of IBS (Irritable Bowel Syndrome) or suspected colorectal malignancy who were found to be normal at colonoscopy and colonic biopsy was normal, were included in the study as control. Two bites of biopsy from the lesion in CD patients were taken for NTM by PCR. In control group two bites were taken for histopathology and two bites were taken for NTM PCR from left side of the colon. We used ITS primer for NTM and IS 900 primer for Mycobacterium avium sub species paratuberculososis (MAP) in PCR. We extracted the DNA from tissue for PCR using QIAamp DNA mini kit.

Results: We studied 34 CD patients and 34 controls. Out of 34 cases 28 were found to be positive for nontuberculous mycobacteria (NTM) and 6 were negative. Out of 34 controls only 8 were found to be positive for nontuberculous mycobacteria (NTM) and 26 were negative. Odds ratio 15.17 (95 % CI 4.07-60.75) and P value was significant (0.001). Among them we couldn’t detect MAP neither in cases nor in controls.
 

Conclusions: From this study it appears that NTM other than MAP may have association with Crohn's disease in Bangladesh.

Abstract:

Gluten, the largest complex protein component of a cereal grain, contains high levels of gliadin and glutenin known as prolamines. Similarly, a high concentration of prolamines was found in barley and rye, so the term ‘gluten’ has become synonymous with the protein content in all three cereals. Researchers have identified gluten to be the main etiologic and causative agent of coeliac disease (CD) in genetically predisposed individuals and a strict gluten-free diet is an essential part of treatment. Not so long ago, the possible role of gluten as the causative agent of other illnesses and not just coeliac disease (CD) spurred the considerable attention of both the medical and general public. Another well-known condition that requires the elimination of wheat proteins is the wheat allergy (WA). At the same time, many people who do not suffer from either CD or WA, exhibit a variety of symptoms that disappear while on a gluten-free diet (GFD). The term non-coeliac gluten sensitivity (NCGS) was used to describe this status which, together with CD and WA, makes a spectrum of gluten-mediated disorders. What non-coeliac gluten sensitivity actually implies is the subject of discussion and the prevalence of such conditions is still unknown. In some patients, the symptoms decrease while adhering to GFD because they have eliminated gluten, while in others, their recovery results from the avoidance of non-protein cereal components, such as sugars belonging to FODMAPs. The confusion about the benefits of GFD resulted in its widespread adoption as the most popular dietary regimen in the USA today, followed by the multibillion-dollar gluten-free food industry (GF). Although the exclusion of gluten from the diet is essential in patients with confirmed CD and BA, the fact is that they make up only a small percentage of those following a GFD, mostly for personal but not medical reasons. Strict adherence to GFD is difficult and costly and involves the risk of nutritional deficiency and weight gain (81%) due to the hyper caloric content of commercial gluten-free foods. GF products are not enriched and may be deficient in fibers, thiamine, folate, vitamin A, magnesium, calcium, and iron. In addition, there is no evidence of a need to eliminate other sources of gluten (rye, barley) in case of non-coeliac gluten sensitivity.

Abstract:

Introduction: In choledocholithiasis subject to the size of the stone and the anatomical structure of the papilla the size of the cross-section in sphincterotomy may vary. Sufficiently large incision in sphincterotomy leads to the increase in the incidence of complications after ERCP as perforation, cholangitis, and pancreatitis.

Materials & Methodology: We performed 77 ERCP (endoscopic retrograde cholangio-pancreatography) operations in patients with a diagnosis of "choledocholithiasis". In the first group (59 patients) we performed standard sphincterotomy incision in 11, 12 or 13 o’clock direction, in the second group (18 patients) - "radial" sphincterotomy. The technique of "radial" sphincterotomy we developed allows to make several lateral incisions in 11, 12 and 13 o’clock directions. Thus, the main incision can be made up to transverse fold, and other radial incisions shall be made below the transverse folds, without going beyond the boundaries of the assumed course of intramural choledoch. Thus, the complete cross section of the incision with additional insections at the radial sphincterotomy becomes 1.5 times larger than the main incision in standard sphincterotomy.

Results: In the first group periampullary diverticulum was 16.7%, while in the second group - 47.4%. Number of stones in the first group – 2.25±0.49, in the second – 2.22±0.32, sizes of the stones – 10.07±4.93 and 19.01±3.31 mm, respectively. In the first group, complications occurred in 3 (5.08%) patients: in 1 of them - post-ERCP pancreatitis, in 2 - bleeding during the session. In the second group, only 1 (5.5%) patient had pancreatitis and other early and late complications. In the first group with 3 patients - the common bile duct stone removal was achieved in two sessions with a few day interval, the remaining - in a single session. In the 2nd group, all patients required only one session. No cases of mortality occurred in any of the groups.

Conclusions: Radial sphincterotomy technique was substantiated from anatomical and mathematical aspects. The proposed technique is a safe way to increase the area of dissected papillae ensuring efficient removal of large stones through such incision.

Abstract:

Statement of the Problem: In 1953, Aird et al. found an association between blood group A and gastric cancer, and between blood group O and peptic ulcer disease (PUD). Further research demonstrated relationships between ABO blood groups and some diseases. No studies included Rh blood groups in the analysis. There is a controversy among studies investigating the association of ABO blood groups with gastric cancer and PUD. This study aims to investigate the relationship between Rh and ABO blood groups and the incidence of gastric cancer and PUD. To our knowledge, this is the first study that includes Rh blood groups in the investigation.

Methodology: We chose case-control design. Participants underwent esophagogastro - duodenoscopy (EGD) during 2016 and 2017 in Aleppo University hospital. We did ABO and Rh typing for all participants. Biopsies were done when indicated. We formed four case groups: benign PUD group (n=276), benign gastric ulcer group (n=125), benign duodenal ulcer group (n=169), gastric cancer group (n=26). The control group (n=276) consisted of participants whose EGDs were normal or revealed only gastritis or duodenitis. We used ODDs Ratio with 95% confidence interval and P-value to evaluate statistical significance of differences between groups.

Findings: There is no significant relationship between Rh blood groups and gastric cancer or PUD. There is no relationship between ABO blood groups and PUD. There is an increased risk of gastric cancer among blood group A. Non-A groups revealed no significant risk. 100% of biopsies showed H. pylori.

Conclusion: After comparing our findings to available literature, we suggest larger-scale studies to investigate the association of non-A groups with gastric cancer, and Rh groups with gastric cancer and PUD. We recommend studying the feasibility of establishing screening programs for gastric cancer in people with blood group A. We should determine the prevalence of H.pylori infection in Syria.
