Abstract
Gastrointestinal (GI) mucosal lesions are common in chronic kidney disease (CKD), end-stage renal disease (ESRD), and in post-renal transplant period. However, etiology of mucosal lesions pre- and post-transplant is very different. Gastropathy in non-transplant ESRD patients usually develops because of uremia, chronic anemia, and fluctuations in the gastric blood supply during hemodialysis, eventually leading to uremic gastritis. Gastropathy in post-transplant patients tends to be associated with immunosuppressive therapies. Helicobacter pylori infection is more prevalent in uremic patients than in post-transplant patients. Uremia can also lead to uremic arteriolopathy and autonomic nervous system dysfunction, which can present with GI symptoms mimicking uremic gastropathy. Post-transplantation immunosuppressive therapies have been linked to GI mucosal lesions as well. These lesions carry a poor prognostic factor disrupting the function of the GI tract, which in turn affects the pharmacokinetics of the immunosuppressive drugs eventually leading to poor graft survival and increased mortality. Mycophenolate mofetil is one of the agents more associated with intestinal erosions. Recognizing uremic gastropathy and intervening early helps prevent post-transplant GI complications. Acid controlling therapies can be an effective prophylaxis against both gastropathies. Using enteric-coated formulation for immunosuppressive agents may slow down the mucosal insult. Treatment of H. pylori in both patient populations may help prevent further mucosal injury. Lastly, timely screening for symptoms may help start treatment early and prevent progression to serious gastropathy.

Abstract
Upper gastrointestinal (GI) abnormality is believed to be higher in patients with end-stage renal disease (ESRD) which can make a big trouble for whom undergo kidney transplant. We conducted this study to assess upper GI findings of patients with ESRD. In the present retrospective study we recorded upper GI endoscopy results in hemodialysis patients who were candidate for renal transplantation during a 10-year period. We reviewed files of 1256 patients with a mean age of 37.6 ± 13.4 years. Half of patients (50.6%) had an abnormal endoscopy. Two most common abnormalities were mild gastritis (35.6%) and gastro-esophageal reflux disease (16.7%). GI ulcers were observed in 11% of patients. Duodenal ulcer was the most common ulcer which was seen in 6.8% of patients. Helicobacter pylori was positive in 32.9% of patients and correlated with GI lesions (P = 0.000, r = 0.371). Longer dialysis duration and older patients revealed more upper GI abnormality (P = 0 .032, <0.001). As long as more than half of our patients have at least one upper GI involvement, we recommended that endoscopy must be done as a pretransplantation evaluation for patients without symptoms who have risk factors for ulcers.

Abstract
Background/Aims Insufficient systematic reviews were conducted in the previous meta-analyses about the prevalence of Helicobacter pylori infection in patients with chronic kidney disease (CKD). The aim of this study was to evaluate the prevalence of H. pylori infection in patients with CKD. Methods A systematic review of studies that evaluated the prevalence of H. pylori infection in patients with CKD compared to a control group was performed. Only studies with adult patients were included, and studies with renal transplant recipients or diabetic nephropathy patients were excluded. Random-effects model meta-analyses with sensitivity analyses and subgroup analyses were conducted to confirm the robustness of the main result. A meta-regression analysis was conducted to explore the influence of potential heterogeneity on the outcomes. The methodological quality of the included publications was evaluated using the Risk of Bias Assessment tool for Nonrandomized Studies. Publication bias was also assessed. Results In total, 47 studies were identified and analyzed. The total prevalence of H. pylori infection was 48.2% (1,968/4,084) in patients with CKD and 59.3% (4,097/6,908) in the control group. Pooled analysis showed a significantly lower prevalence of H. pylori infection in patients with CKD (vs control group: odds ratio, 0.64; 95% confidence interval, 0.52 to 0.79). Sensitivity analyses revealed consistent results, and meta-regression analysis showed no significant confounders. No publication bias was detected. Conclusions The results of this study suggest a lower prevalence of H. pylori infection in patients with CKD.

Abstract
INTRODUCTION Despite the frequency with which anaemia is present in patients with chronic kidney disease (CKD), its relationship with gastrointestinal lesions has not been studied. METHOD A cross-sectional, analytical, observational study involving one year of recruitment was carried out to determine the prevalence of endoscopic gastrointestinal lesions and associated risk factors in asymptomatic patients with chronic kidney disease stages 1-5 and anaemia who had a positive qualitative immunochemical faecal occult blood test. RESULTS A total of 9,658 patients with CKD were analysed, of which 286 (2.9%) had anaemia; 198 had a positive faecal occult blood test (47% male, 71.1±11.8 years). The endoscopic study revealed 255 lesions, with at least one lesion in 68.2% of patients, with the most prevalent being: adenomatous colorectal polyps (39.6%), acute lesions of the gastric mucosa (22.6%), neoplastic lesions 15.1%), angiodysplasia (14.4%), oesophagitis (8.4%), inflammatory bowel disease (4.8%) and ischaemic colitis (3.1%). Uraemia and acetylsalicylic acid were identified as risk factors for acute gastric mucosal lesions. Angiodysplasia was associated with alcoholism, a more advanced stage of chronic kidney disease, anaemia, and lack of response to erythropoiesis-stimulating agents. Age and refractory anaemia were risk factors for adenomatous polyps and colorectal cancer. CONCLUSION Renal patients with anaemia could benefit from an endoscopic study due to their high prevalence of gastrointestinal lesions, particularly adenomatous polyps and colorectal cancer, which are more common in those over 50 years of age with CKD stages 3-5.

Abstract
BACKGROUND/OBJECTIVES The reported risk of chronic kidney disease (CKD) in patients with Helicobacter pylori infection is conflicting. This meta-analysis was conducted to summarize all available data and to estimate the prevalence and association between H. pylori and kidney disease and CKD. METHODS Comprehensive literature review was conducted using MEDLINE and EMBASE database through October 2016 to identify studies that reported the prevalence or the association between H. pylori infection and non-dialysis-dependent kidney diseases or CKD. Effect estimates from the individual study were extracted and combined using random-effect, generic inverse variance method of DerSimonian and Laird. RESULTS Of 4546 studies, nine cross-sectional studies met the eligibility criteria and were included in the meta-analysis. The estimated prevalence of H. pylori infection among subjects with kidney disease was 53% (95% CI 45-61%). The pooled OR of H. pylori in patients with non-dialysis-dependent kidney diseases was 1.20 (95% CI 0.73-1.97) when compared with the patients without kidney diseases. The meta-analysis was then limited to only studies evaluating the risk of H. pylori in CKD; the pooled OR of H. pylori in patients with CKD was 1.00 (95% CI 0.58-1.71). CONCLUSIONS The estimated prevalence of H. pylori in patients with non-dialysis-dependent kidney diseases is 53%. This study does not support the association between H. pylori infection and non-dialysis-dependent kidney diseases nor CKD.

Abstract
AIM To investigate the prevalence and association of Helicobacter pylori (H. pylori) with end-stage renal disease (ESRD).
METHODS SA comprehensive literature search was completed from inception until October 2016. Studies that reported prevalence, relative risks, odd ratios, hazard ratios or standardized incidence ratio of H. pylori among ESRD patients were included. Participants without H. pylori were used as comparators to assess the association between H. pylori infection and ESRD. Pooled risk ratios and 95%CI was calculated using a random-effect model. Adjusted point estimates from each study were combined by the generic inverse variance method of DerSimonian and Laird.
RESULTS Of 4546 relevant studies, thirty-seven observational studies met all inclusion criteria. Thirty-five cross-sectional studies were included in the analyses to assess the prevalence and association of H. pylori with ESRD. The estimated prevalence of H. pylori among ESRD patients was 44% (95%CI: 40%-49%). The pooled RR of H. pylori in patients with ESRD was 0.77 (95%CI: 0.59-1.00) when compared with the patients without ESRD. Subgroup analysis showed significantly reduced risk of H. pylori in adult ESRD patients with pooled RR of 0.71 (95%CI: 0.55-0.94). The data on the risk of ESRD in patients with H. pylori were limited. Two cohort studies were included to assess the risk of ESRD in patients with H. pylori. The pooled risk RR of ESRD in patients with H. pylori was 0.61 (95%CI: 0.03-12.20).
CONCLUSION The estimated prevalence of H. pylori in ESRD patients is 44%. Our meta-analysis demonstrates a decreased risk of H. pylori in adult ESRD patients.

Abstract
Carbon-labeled urea breath tests, which have high sensitivity and specificity, are the preferred method used in epidemiological studies, screening dyspeptic patients and assessing eradication or recurrence of Helicobacter pylori infection. The principle of the (13)C-urea breath test relies upon the ability of the H. pylori urease to hydrolyze the orally administered (13)C-urea. The BreathID (Exalenz Bioscience Inc., Union, NJ, USA) provides a competitive solution for breath testing, including unique features such as automatic continuous breath collection and analysis. This is an unattended convenient test, with no human error as the correct part of the breath is collected and patients' assistance is not required. The test results are available in real time at the point of care and enable shortened breath testing procedures. Additionally, several studies showing expanded utility of the BreathID in pediatrics, after therapy and during proton pump inhibitors intake, further support the safety and performance of the BreathID in the diagnosis of H. pylori.

Abstract
BACKGROUND Hemodialysis is the most common method of renal replacement therapy for treatment of acute and chronic kidney failure. Helicobacter pylori (H. pylori) plays a major role in development of peptic ulcer, gastric neoplasms, and lymphoma as well as increased risk of cardiovascular disorders in hemodialysis patients. OBJECTIVES In this study the diagnostic values of noninvasive tests [i.e. urea breath test (UBT), helicobacter pylori stool antigen test (HPSA) and serology] in diagnosis of H. pylori infection in hemodialysis patients have been studied. PATIENTS AND METHODS All patients undergoing hemodialysis in Fatemieh Hospital, Semnan, Iran, were enrolled in the study, and their H. pylori status were assessed by using non-invasive tests including UBT, HPSA and serology. Patients with at least two out of 3 positive tests were considered infected with H. pylori. RESULTS The sensitivity, specificity, and positive and negative predictive values of the tests used in diagnosing H. pylori infection were 62.5%, 65.4%, 62.5% and 65.4% for UBT, 100%, 72.2%, 58.3% and 100% for serology, and 100%, 75%, 60.9% and 100% for fecal antigen test, respectively. CONCLUSIONS This study showed that H. pylori serology and stool antigen tests have higher diagnostic values than UBT, and they are more reliable than UBT in diagnosis of H. pylori infection in hemodialysis patients.

Abstract
AIM Gastrointestinal (GI) symptoms are reported to be common among patients with chronic disorders including end-stage renal disease (ESRD). This questionnaire study assessed the prevalence of GI symptoms among patients undergoing hemodialysis (HD) and to correlate with the presence of diabetes mellitus and psychosomatic symptoms in Asian patients with ESRD. METHODS A total of 123 patients (male 47.2%) participated in this study. GI symptoms (upper GI: anorexia, nausea, vomiting, odynophagia, dysphagia, early satiety, heartburn, dyspepsia and lower GI: abdominal bloating, non-epigastrium abdominal pain, bowel habit and bleeding per rectum) and psychosomatic symptoms (anxiety, backache, depression, headache and insomnia) in the previous 12 months were enquired and compared with age and gender matched controls (n = 197). RESULTS The mean age of patients was 51.8 ± 12.9 years with mean duration of HD of 28 ± 38.2 months. Overall, 70.7% of ESRD patients had experienced any GI symptoms; upper GI, 65% and lower GI, 34.1%, significantly more than controls (P < 0.05). ESRD patients had more anorexia, nausea, vomiting, dyspepsia, irregular bowel habit and bleeding per rectum (all P < 0.05). Overlap of upper and lower GI symptoms was reported by 34.1%, significantly higher than control (14.2%, P < 0.05). ESRD patients also experienced significantly more anxiety, depressive symptoms and insomnia (all P < 0.05). Among the patients with ESRD, the presence of any psychosomatic symptoms correlated significantly with the presence of any upper or lower GI symptoms and overlapping of GI symptoms. Such correlations were not seen with diabetes mellitus. CONCLUSION Gastrointestinal and psychosomatic symptoms are common among our Asian patients with ESRD undergoing regular HD. The presence of underlying psychosomatic symptoms but not diabetes mellitus correlated significantly with the presence of GI symptoms.

Abstract
BACKGROUND In dialysis patients, chronic infections have been associated with cachexia and anorexia. OBJECTIVES This study was carried out to determine the association between Helicobacter pylori (HP) infection and body mass index (BMI) in hemodialysis (HD) patients. PATIENTS AND METHODS Ninety eight patients were divided into two groups of negative (group 1) and positive (group 2), for HP. BMI of all patients was measured at the beginning and in group2 after six months following eradication of HP. Before dialysis, various paraclinical parameters were checked at the same intervals. RESULTS Fifty-nine patients were enrolled in group 1 and 39 patients in group 2. The means of BMI in groups 1 and 2 were 23.4±3.7 and 25.8±4.4kg/m², respectively. Prior to the study, there was no significant difference for BMI, duration of HD and paraclinic data between two groups. Group 2 took anti HP therapy and eradication occurred in 30 of them. In this group six months after eradication of HP, the BMI was significantly decreased from 25.02±4.4 to 24.4±4.0 kg/m² (P = 0.001). Also six months following the eradication of HP, the mean of serum albumin level was significantly declined from 4.2 to 3.7 g/L (P<0.001). There was also significant decrease in cholesterol (P=0.001), blood urea nitrogen (P=0.005) and calcium (P=0.02). However, significant increase in hemoglobin level was also seen (P=0.03). CONCLUSIONS The results of this study show that eradication of HP has an impact on BMI. The results need to be investigated with larger cases.

Abstract
Background Helicobacter pylori eradication with clarithromycin is more expensive than with azithromycin. Objectives This study aimed to compare the effectiveness of these two antibiotics in eradicating H. pylori in hemodialysis (HD) patients. Patients and Methods This is a prospective, randomized, double-blinded clinical trial analysis of HD patients. Patients who had dyspepsia and showed positive results for two of three tests, anti-H. pylori serology, H. pylori stool antigen (HpSAg), or Urease Breath Test (UBT), were included in the study. The subjects consisted of 39 dialysis patients who were randomly divided into two groups that received medication twice daily. Group OAC received 20 mg omeprazol, 500 mg amoxycilin, and 250 mg clarithromycin, and Group OAAz received 20 mg omeprazol, 500 mg amoxicillin, and 250 mg azithromycin. Both regimens were administered for 14 days. Eradication was investigated by performing the UBT and the HpSAg test eight weeks later. Results This study began with 39 patients, 37 of which completed the treatment schedule (20 males and 17 females, mean age 59 years). Two patients died due to MI before beginning treatment. In the OAC group, negative results on the UBT and HpSAg tests were found in 82.4% and 88.2% of the participants, respectively. In the OAAz group, these values were 80% and 85%, respectively. The data showed that the difference between the two regimens was not significant (P = 1.0). Conclusions According to the data, no differences in eradication rates were apparent between the azitromycin and the claritromycin regimens. However, lower cost and fewer complaints could be considered as an advantage of the triple therapy with azithromycin.

Abstract
Melioidosis is a disease of humans caused by opportunistic infection with the soil and water bacterium Burkholderia pseudomallei. Melioidosis can manifest as an acute, overwhelming infection or as a chronic, recurrent infection. At present, it is not clear where B. pseudomallei resides in the mammalian host during the chronic, recurrent phase of infection. To address this question, we developed a mouse low-dose mucosal challenge model of chronic B. pseudomallei infection and investigated sites of bacterial persistence over 60 days. Sensitive culture techniques and selective media were used to quantitate bacterial burden in major organs, including the gastrointestinal (GI) tract. We found that the GI tract was the primary site of bacterial persistence during the chronic infection phase, and was the only site from which the organism could be consistently cultured during a 60-day infection period. The organism could be repeatedly recovered from all levels of the GI tract, and chronic infection was accompanied by sustained low-level fecal shedding. The stomach was identified as the primary site of GI colonization as determined by fluorescent in situ hybridization. Organisms in the stomach were associated with the gastric mucosal surface, and the propensity to colonize the gastric mucosa was observed with 4 different B. pseudomallei isolates. In contrast, B. pseudomallei organisms were present at low numbers within luminal contents in the small and large intestine and cecum relative to the stomach. Notably, inflammatory lesions were not detected in any GI tissue examined in chronically-infected mice. Only low-dose oral or intranasal inoculation led to GI colonization and development of chronic infection of the spleen and liver. Thus, we concluded that in a mouse model of melioidosis B. pseudomallei preferentially colonizes the stomach following oral inoculation, and that the chronically colonized GI tract likely serves as a reservoir for dissemination of infection to extra-intestinal sites.

Abstract
Gastrointestinal complications are known to commonly occur in patients with renal failure. Uremia and dialysis have long been speculated to increase the risk of lesions in the gastrointestinal tract and accessory organs. In addition, gastrointestinal procedures such as gastrointestinal bypass surgery and the administration of colonoscopy preparations can lead to the development of renal complications. Results from studies that have attempted to define the association between renal dysfunction and gastrointestinal complications are, however, conflicting and limited by small and varied sample populations. No clear management guidelines currently exist for many of the gastrointestinal problems that accompany renal failure. This Review examines the existing data on gastrointestinal complications in patients with chronic kidney disease and end-stage renal disease and aims to outline the etiology and management of common gastrointestinal disorders in such patients.

Abstract
BACKGROUND/AIMS Gastrointestinal (GI) symptoms are common in patients with chronic renal failure. Patients with chronic renal failure on dialysis have a high consumption of proton pump inhibitors (PPIs) and long-term treatment is very common. The aim of the study was to investigate the prevalence of gastroesophageal reflux symptoms (GORS), dyspeptic symptoms, and PPI treatment in patients with chronic renal failure on dialysis and to compare the impact of the different types of dialysis on these upper GI symptoms and PPI treatment. METHODS One hundred and twelve peritoneal dialysis (PD) patients and 157 hemodialysis (HD) patients participated in the study. The patients were asked to complete two questionnaires: Gastrointestinal Symptom Rating Scale measuring GI symptoms in general and a GI symptom questionnaire evaluating upper GI tract symptoms specifically. Information about the use of and indication for PPI treatment and onset of GI symptoms was obtained by interviewing the patients and/or reviewing the medical records. RESULTS Dyspepsia was more common among PD patients compared with HD patients (55 vs. 38%, P=0.003). The start of dialysis tended to have a greater impact on dyspepsia (P=0.09) and GORS (P=0.09) in PD patients than in HD patients. The proportion of patients who started PPI treatment after onset of dialysis was high but did not differ between PD and HD patients (51 vs. 44%, P=0.43). A higher proportion of women with chronic renal failure started PPI treatment after the onset of dialysis than men with chronic renal failure (P=0.002). CONCLUSION Dyspepsia and GORS leading to PPI treatment are common in CRF patients on dialysis. Dialysis in general and the type of dialysis seem to affect the presence of upper GI symptoms.

Abstract
The aim of this study is to evaluate the prevalence of GI symptoms, endoscopic abnormalities, histologic gastritis and Helicobacter pylori infection in children with End Stage Renal Disease (ESRD) undergoing maintenance hemodialysis. Upper endoscopy and gastric biopsy were performed in 31 consecutive ESRD children from 2002-2007, before renal transplantation. H. pylori status was determined by urease test and histology. The mean age of patients was 11 +/- 3.3 years (4-16 year). The mean duration of dialysis was 12.4 +/- 11 months (1.5-54 months). Seventeen patients (54.8%) were symptomatic. Twenty patients (64.5%) had endoscopic abnormalities. Antral erythema, esophagitis, antral nodularity and diffuse gastritis were common endoscopic findings. Endoscopic abnormalities were more common in symptomatic patients than asymptomatic patients (p < 0.05). Twenty patients (64.5%) were H. pylori positive. There was no statistical correlation between age, sex, serum creatinine level, presence of any symptoms and endoscopic abnormalities with H. pylori positivity. The mean duration of dialysis in H. pylori negative patients was significantly longer in comparison with H. pylori positive patients. High prevalence of eodoscopic abnormalities and H. pylori infection in both symptomatic and asymptomatic patients emphasize the necessity of upper GI evaluation in ESRD children before renal transplantation.

Abstract
AIM Lesions of the gastrointestinal tract are frequent finding in uremic patients but their actual nature is not completely clear. The aim of this study was to detect any correlation between endoscopic lesions of patients with different levels of renal insufficiency. METHODS This prospective study involved 244 cases, with dyspeptic difficulties including 124 patients in different stages of renal insufficiency, and a control group of 120 patients with normal renal function. Upper esophagogastroscopy was performed in all patients because of the appearance of dyspeptic difficulties. Helicobacter pylori infection was detected by the urease test. RESULTS H. pylori infection (P=0.009), gastric erosions (P=0.019), gastric ulcer (P=0.002), and duodenal ulcer (P<0.001) were more common in the control group of patients. Significant negative correlations were found between the level of renal insufficiency and H. pylori infection (Kendall's tau=-0.346; P=0.003), stomach erosions (Kendall's tau=-0.272; P=0.019), stomach ulcer (Kendall's tau=-0.347; P=0.003), and duodenal ulcer (Kendall's tau=-0.531; P<0.001). CONCLUSIONS In patients with end stage renal disease, endoscopic lesions of the gastrointestinal tract are detected less frequently in relation to patients without kidney disease.

Abstract
BACKGROUND The role of Helicobacter pylori in the pathogenesis of peptic ulcer disease in patients with uraemia remains unclear. AIM To evaluate the long-term effect of H. pylori eradication in these patients. METHODS Uraemic and non-uraemic patients with peptic ulcer were enrolled in this study. Patients having history of non-steroidal anti-inflammatory drugs use or cardiovascular disease that need aspirin use were excluded. After confirmation of H. pylori infection, they received a triple therapy and were followed up for 2 years. RESULTS Between September 1999 and December 2005, 34 patients (41%) of the end-stage renal disease [H. pylori (+) group] and 67 (84%) of the non-uraemic patients with peptic ulcer disease (PU group) received anti-H. pylori therapy. After triple therapy, 32 (94%) from the end-stage renal disease group and 64 (96%) from the peptic ulcer group obtained successful eradication. During the 2-year follow-up, three patients in the end-stage renal disease group were excluded because of the presence of cardiovascular disease and aspirin use in two cases and died of heart failure in one case; two patients in peptic ulcer group refused follow-up. Finally, 29 uraemic and 62 non-uraemic patients had achieved the follow-up. Recurrence of peptic ulcer was more in the end-stage renal disease group than in the peptic ulcer group with intention-to-treat analysis (eight of 32, 25% vs. two of 64, 3%, P = 0.001, OR: 10.0, 95% CI: 1.979-50.540) or per-protocol analysis (eight of 29, 28% vs. two of 62, 3%, P < 0.001, OR: 11.4, 95% CI: 2.245-58.168). CONCLUSIONS Peptic ulcer recurrence after H. pylori eradication is higher in end-stage renal disease patients with peptic ulcer than in peptic ulcer patients without renal disease. Factors aside from H. pylori play an important role in peptic ulcer recurrence in end-stage renal disease patients.

Abstract
Introduction/Aim. Gastric acid is a key factor in the pathophysiology of gastroesophageal reflux disease. A plausible mechanism by which the Helicobacter pylori infection might protect against reflux disease is by its propensity to produce atrophic gastritis. The aim of the study was to establish the influence of Helicobacter pylori infection on the occurrence of gastroesophageal reflux in patients with different stages of renal insufficiency. Methods. The examination was organized as a prospective, clinical study and involved 68 patients ? 33 patients with preterminal stage of renal failure and 35 patients with terminal renal insufficiency. Due to dyspeptic difficulties, in all the patients there was preformed upper esophagogastroscopy and Helicobacter pylori infection was found by ureasa test. Results. The patients with preterminal renal insufficiency were significantly younger than patients with terminal renal failure (53.4?11.1 vs. 65.4?12.3 years; p = 0.014). There was found a statistically significant difference between the groups in Helicobacter pylori infection (p = 0.03), hiatal hernia (p = 0.008), gastroesophageal reflux disease (p = 0.007), and duodenal ulcer (p = 0.002). Using the multiple non-parametric correlative analysis there was confirmed a negative correlation between Helicobacter pylori infection and gastro-esophageal reflux disease (Kendal ?B = -0.523; p = 0.003) and hiatal hernia (Kendal ?B = 0.403; p = 0.021), while there was found a positive correlation between gastro-esophageal reflux disease and hiatal hernia (Kendal ?B = 0.350; p = 0.044). Conclusion. Helicobacter pylori infection is a significant protective parameter of the incidence of gastro-esophageal reflux disease in patients with both pre-terminal and terminal renal insufficiency.

Abstract
Gastrointestinal complications are common after kidney, liver, pancreas, heart, and lung transplantation. Complications can include gastrointestinal conditions preceding the transplantation, viral, fungal, and bacterial gastrointestinal infections, and gastrointestinal side effects of medications including immunosuppressive agents. Establishing the etiology of gastrointestinal complaints is often difficult because any one or a combination of these factors might be contributory in the same patient.
