Abstract
Terminal ileitis is a common finding in clinical practice and is often associated with Crohn's disease. However, other pathologies must be considered particularly those resulting from side effects of drugs. We report a case of an 18-year-old female that underwent renal transplant under mycophenolate sodium, tacrolimus, and prednisolone admitted for abdominal pain, diarrhea and weight loss. Abdominal ultrasound revealed terminal ileum wall thickness, extending through 6,6 cm, while a subsequent Ileocolonoscopy revealed normal ileal mucosae but congestive cecum mucosae with superficial ulcers. Histology revealed unspecific chronic inflammation. Under the hypothesis of drug-induced enterocolitis, and after multidisciplinary discussion, mycophenolate sodium was suspended, with a rapid recovery without further treatment. This case highlights the challenge of diagnosing ileocolitis and demonstrates that MS-induced lesions can present clinical and endoscopic changes similar to those seen in Crohn's disease. Although enteric-coated MS has delayed absorption from the GI tract compared to MMF, which might reduce GI adverse events, this difference does not seem to be statistically significant.

Abstract
BACKGROUND Mycophenolate mofetil (MMF) is an immunosuppressive drug that is frequently prescribed to patients with rheumatological diseases. MMF's side effects include abdominal discomfort, nausea, vomiting, and other gastro-intestinal side effects, which typically appear in the first few months of treatment. However, late-onset diarrhea does not rule out the presence of MMF-induced colitis, which can be misdiagnosed since it is linked to a broad range of histopathological characteristics, including alterations that resemble inflammatory bowel disease, graft-versus-host disease, and ischemia. The differences in treatment response may be explained by the complexity of the histopathologic characteristics. CASE PRESENTATION Here we present a case of a 29-year-old Arabian female with lupus nephritis who started on MMF as induction therapy. In two months, the patient was presented to the Emergency Department with diarrhea and manifestations of severe dehydration. Infectious diseases and adverse drug events were suspected, so the patient was admitted for further workup, and MMF was stopped. The patient was diagnosed with MMF-induced colitis based on colonoscopy and histological findings. Fourteen days after stopping MMF, she was within her baseline. CONCLUSION The purpose of this paper is to report a case of early-onset MMF-induced colitis in a patient with lupus nephritis who had started MMF as induction therapy. A review of the available literature on this uncommon immunosuppressive effect is also presented.

Abstract
Mycophenolate mofetil (MMOF) is a commonly used immunosuppressive prodrug in kidney transplant patients. However, it is not without side effects. The most common of these is diarrhea which inadvertently leads to colonoscopic and endoscopic evaluation when all other workup returns negative. Colonoscopies often show diffuse ulcers and colitis changes depending on the degree of diarrhea. In rare situations, MMOF-induced ischemic colitis may occur on gross endoscopy. We describe an unusual phenomenon of an adult male status post renal transplant with histopathologically diagnosed MMOF-induced colitis who developed gross endoscopic findings concerning ischemic colitis. Our case highlights the importance of recognizing that MMOF-induced colonic changes can rarely mimic ischemic colitis. With this in mind, we aim for gastroenterologists to better understand the varying endoscopic colonic findings of this immunosuppressive drug.

Abstract
Pediatric primary systemic vasculitides are a complex group of diseases. Vasculitis subgroups are mainly determined according to the size of the predominantly affected vessels. In patients with primary systemic vasculitis, the location of vascular involvement, the size of the vessels, the extent of vascular damage, and the underlying pathology determine the disease phenotype and severity. Cardiac involvement is rare in some pediatric vasculitis, such as IgA vasculitis and polyarteritis nodosa, while it is more common in some others like Kawasaki disease and Takayasu arteritis. On the other hand, chronic inflammation in the setting of systemic vasculitis forms a major cardiovascular risk factor. Accelerated atherosclerosis and the tendency to thrombosis are the main issues determining the cardiovascular risks in pediatric systemic vasculitis. Early diagnosis and treatment are essential in these patients to minimize morbidity and mortality. In this review, we aimed to raise physicians' awareness of cardiac involvement and cardiovascular risks in pediatric patients with primary systemic vasculitis.

Abstract
El micofenolato de mofetil es un medicamento usado para la prevención del rechazo de aloinjertos en pacientes con trasplante de órganos. La colitis eosinofílica por micofenolato es una condición reconocida en pacientes con antecedente de trasplante renal y diarrea persistente, en la cual es necesaria la toma de biopsia para lograr un diagnóstico y tratamiento apropiados. Se presenta el caso de un niño de 11 años con diarrea; se realizó biopsia de colon que mostró edema e infiltrado inflamatorio eosinofílico en lámina propia con formación de microabscesos, con daño epitelial y de las criptas. Dada la ausencia de otra causa del cuadro clínico, se retiró el micofenolato del esquema de tratamiento, con resolución de la sintomatología. La escala de naranjo para causalidad de reacción adversa a medicamentos fue definitiva con un puntaje de 10. Se aporta a la literatura con la caracterización de los hallazgos histopatológicos en la lesión del colon inducida por micofenolato.

Abstract
Mycophenolate mofetil (MMF) is an immunosuppressive medication used for the management of various autoimmune diseases, and patients with bone marrow and solid organ transplants. Gastrointestinal side effects are seen 45% of the time and they include nausea (29%), vomiting (23%), constipation (38%), diarrhea (50%-92%), and colitis (9%). In 98% of cases, resolution of diarrhea occurs within 20 days upon discontinuation of the MMF. Data is scarce regarding approach in the treatment of MMF-induced colitis. We report a case of MMF-induced colitis diagnosed by colonoscopy and histopathology. This case illustrates the challenges encountered while managing MMF-induced colitis.

Abstract
AIM To describe all abnormal histological findings and their associated endoscopic presentation in patients using mycophenolate mofetil (MMF).
METHODS A retrospective review of all individuals prescribed MMF within 6 mo of a colonoscopy or flexible sigmoidoscopy between 07/2009 and 09/2015 was performed within Northwell Health system. Records were analyzed for age, gender, procedure indication, MMF indication, and both gross and microscopic findings. Only reports with abnormal histology were included.
RESULTS One hundred and eighty-four procedures from 170 patients were found, of which 39 met inclusion criteria. Fifty-one point three percent were female. MMF was used for solid organ transplant in 71.8%. Diarrhea was the indication for 71.8% of colonoscopies. Fifty-nine percent of reports revealed gross and microscopic abnormalities while 41.0% had only microscopic findings. Only 11 patients’ reports (28.2%) indicated a specific histopathology of MMF colitis. Among the entire group, only 23.1% of abnormal histology was isolated proximal to the splenic flexure.
CONCLUSION Our results demonstrate a high rate of left sided disease and microscopic findings without gross mucosal abnormalities among patients using MMF. Also, a broader definition of MMF-colonopathy may be appropriate, with a majority of our abnormal histology falling outside of the more narrowly defined MMF-colitis category. Given the high frequency of isolated microscopic abnormalities and distal disease, sigmoidoscopy with random biopsies may be an appropriate, less invasive initial endoscopic examination in selected MMF patients.

Abstract
The practice of anatomic pathology, and of gastrointestinal pathology in particular, has been dramatically transformed in the past decade. In addition to the multitude of diseases, syndromes, and clinical entities encountered in daily clinical practice, the increasing integration of new technologic and molecular advances into the field of gastroenterology is occurring at a fast pace. Application of these advances has challenged pathologists to correlate newer methodologies with existing morphologic criteria, which in many instances still provide the gold standard for diagnosis. This review describes the impact of new technologic and molecular advances on the daily practice of gastrointestinal and hepatobiliary pathology. We discuss new drugs that can affect the gastrointestinal tract and liver, new endoluminal techniques, new molecular tests that are often performed reflexively, new imaging techniques for evaluating hepatocellular carcinoma, and modified approaches to the gross and histologic assessment of tissues that have been exposed to neoadjuvant therapies.

Abstract
The evaluation of a patient with chronic diarrhea can be quite frustrating, as it is expensive and involves multiple diagnostic studies. Moreover, identification of a drug as a cause of chronic diarrhea is a challenge in patients taking multiple medications. The disease may either be associated with intestinal mucosal changes, mimicking diseases such as celiac disease, or purely functional, with no histopathologic change. Drug-induced diarrhea may or may not be associated with malabsorption of nutrients, and a clinical improvement may occur within days of discontinuation of the drug, or may take longer when associated with mucosal injury. Diarrhea in diabetics, often attributed to poor management and lack of control, may be due to oral hypoglycaemic agents. Chemotherapy can result in diffuse or segmental colitis, whereas olmesartan and a few other medications infrequently induce a disease that mimics celiac disease, but is not associated with gluten intolerance. In short, increased awareness of a drug, as a cause for diarrhea and a clear understanding of the clinical manifestations will help clinicians to solve this challenging problem. This article aims to review drug-induced diarrhea to (a) understand known pathophysiological mechanisms; (b) assess the risk associated with frequently prescribed medications, and discuss the pathogenesis; and

Abstract
BACKGROUND Successful treatment of both pediatric autoimmune hemolytic anemia (AIHA) and immune thrombocytopenic purpura (ITP), specifically those that are refractory to first-line therapies, remains unsatisfactory in terms of long-term remission and medication side effects. Here, we propose a novel combination therapy of mycophenolate mofetil (MMF), an adjunct immunosuppressive, and short-term corticosteroids for the treatment of persistent or chronic autoimmune cytopenias in children. This combination may allow for rapid decrease of steroid usage as well as prolonged count stabilization with minimal toxicity to the patient. PROCEDURE Prospective case series of nine patients, six with persistent or chronic ITP and three with persistent or chronic AIHA, between the ages of 5 and 19 years who are being treated with combination therapy consisting of corticosteroids and MMF. RESULTS All patients with ITP (Patients 4-9) and AIHA (Patients 1-3) met complete response (CR) criteria, as they all initially achieved platelet counts 100 × 109 l-1 or more or hemoglobin level greater than or equal to 10 g/dl, respectively, while on combination therapy and then maintained this level or higher while on MMF alone after steroids were discontinued. CONCLUSIONS Our results are very promising, as MMF appears to be an effective and well-tolerated adjunct immunosuppressant that allows for rapid weaning of steroid usage, minimal adverse side effects to the patients, and long-term stabilization of counts, a goal that has not been achieved successfully with other secondary treatment modalities. Therefore, this novel combination therapy may be an excellent alternative for the treatment of persistent or chronic autoimmune cytopenias in the pediatric population.

Abstract
Many drugs and chemical agents can cause enteritis and colitis, producing clinical gastrointestinal side effects, the most common of which are diarrhoea, constipation, nausea and vomiting. Significant histological overlap exists between some patterns of medication or chemical injury and various disease entities. A particular medication may cause multiple patterns of injury and may mimic common entities such as coeliac disease, Crohn's disease, infectious enteritis and colitis. Thus, given the common absence of specific histopathological features, the diagnosis often relies upon thorough clinicopathological correlation. This review concentrates on selected examples of medication-induced injury of the intestinal tract in which the pathology can be recognized, particularly on biopsies, with a focus on newly described medication-induced gastrointestinal effects.
