Abu Khalaf S, Albarrak A, Yousef M, Tahan V. Immune checkpoint inhibitors induced colitis, stay vigilant: A case report. World J Gastrointest Oncol 2020; 12:699-704. [PMID: 32699584 PMCID: PMC7340999 DOI: 10.4251/wjgo.v12.i6.699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Revised: 05/07/2020] [Accepted: 05/20/2020] [Indexed: 02/05/2023] [Imported: 08/29/2023] Open
Abstract
BACKGROUND Colitis is one of the immune-related side effects of immunotherapy. Usually, such type of side effect was reported to develop within a few weeks of treatment initiation, our case started within a few days.
CASE SUMMARY We present a case of a 37-year-old gentleman with bright red loose stools, abdominal pain, and tenesmus. A diagnosis of colitis was made based on endoscopic and histologic findings. Treatment was thereafter continued with oral steroids and discontinuation of the immunotherapy medications. Symptoms resolved after starting the treatment and the patient continued to be symptom-free on subsequent follow-up. The unique about this case report is that the patient developed bloody diarrhea within five days of the 1st immunotherapy cycle, and the patient was on combined ipilimumab and nivolumab.
CONCLUSION Immunotherapy related complications might occur within days from being on immunotherapy; we need more research to open the way for future pathological and clinical research to further understand the pathophysiology behind it.

Abstract
BACKGROUND The rising incidence of Clostridium difficile infection (CDI) in the general population has been recognized by health care organizations worldwide. The emergence of hypervirulent strains has made CDI more challenging to understand and treat. Inflammatory bowel disease (IBD) patients are at higher risk of infection, including CDI. OBJECTIVE A diagnostic approach for recurrent CDI has yet to be validated, particularly for IBD patients. Enzyme immunoassay (EIA) for toxins A and B, as well as glutamate dehydrogenase EIA, are both rapid testing options for the identification of CDI. Without a high index of suspicion, it is challenging to initially differentiate CDI from an IBD flare based on clinical evaluation alone. METHODS Here, we provide an up-to-date review on CDI in IBD patients. When caring for an IBD patient with suspected CDI, it is appropriate to empirically treat the presumed infection while awaiting further test results. RESULTS Treatment with vancomycin or fidaxomicin, but not oral metronidazole, has been advocated by an expert review from the clinical practice update committee of the American Gastroenterology Association. Recurrent CDI is more common in IBD patients compared to non-IBD patients (32% versus 24%), thus more aggressive treatment is recommended for IBD patients along with early consideration of fecal microbiota transplant. CONCLUSION Although the use of infliximab during CDI has been debated, clinical experience exists supporting its use in an IBD flare, even with active CDI when needed.

Use of music during colonoscopy: An updated meta-analysis of randomized controlled trials. World J Meta-Anal 2019; 7:428-435. [DOI: 10.13105/wjma.v7.i9.428] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2019] [Revised: 10/26/2019] [Accepted: 11/15/2019] [Indexed: 02/06/2023] [Imported: 08/29/2023] Open
Abstract
BACKGROUND Music seems to be beneficial in multiple clinical areas. Colonoscopy is a stressful event for patients, especially with conscious sedation. Music during colonoscopy has been evaluated in multiple randomized controlled trials (RCTs) with varied results. Even meta-analyses on the subject over the years have yielded inconsistent conclusions. Therefore, we conducted an up-to-date meta-analysis regarding music during colonoscopy.
AIM To assess the effects of music played during colonoscopy on patients’ perspectives and sedation requirements.
METHODS Multiple large databases were aggressively searched (November 2018). RCTs comparing music to without music during colonoscopy on adult patients were included. Pooled estimates were calculated for sedative medication doses, total procedure time, and patients’ experience, willingness to repeat procedure, and pain scores using odds ratio (OR) and mean difference (MD) with random effects model.
RESULTS Eleven studies (n = 988) were included. Music during colonoscopy showed a statistically significant reduction in procedure times (MD: -2.3 min; 95%CI: -4.13 to -0.47; P = 0.01) and patients’ pain (MD: -1.26; 95%CI: -2.28 to -0.24; P = 0.02) while improving patients’ experience (MD: -1.11; 95%CI: -1.7 to -0.53; P < 0.01) as compared to no music. No statistically significant differences were observed between music and no music during colonoscopy for midazolam (MD: -0.4 mg; 95%CI: -0.9 to 0.09; P = 0.11), meperidine (MD: -3.06 mg; 95%CI: -10.79 to 4.67; P = 0.44), or patients’ willingness to repeat the colonoscopy (OR: 3.89; 95%CI: 0.76 to 19.97; P = 0.1).
CONCLUSION Music appears to improve overall patient experience while reducing procedure times and patient pain. Therefore, music, being a non-invasive intervention, should be strongly considered during colonoscopy.

Abstract
Background:
Probiotics can be viewed as biological agents that modify the intestinal microbiota
and certain cytokine profiles, which can lead to an improvement in certain gastrointestinal
diseases, including diarrhea, inflammatory bowel disease, and liver disease.
Discussion:
Consumption of probiotics in their various forms, including yogurt, functional foods, and
dietary supplements, is frequently encountered worldwide. Often, however, the correct prescription of
these agents is dampened due to a lack of knowledge of the scientific evidence and the different presentations
and microbial compositions of the currently available probiotic options. Here, we provide an
up-to-date review of the evidence of probiotics in the prevention and treatment of various gastrointestinal
diseases.

Abstract
Fecal microbiota transplantation is becoming a growing therapy for a variety of indications, including recurrent or refractory Clostridium difficile infection (CDI), as well as many other gastrointestinal and extra-intestinal diseases. In fact, fecal microbiota transplantation is now strongly recommended as the treatment of choice for multiple recurrences of CDI, given its strong efficacy and a favorable short-term side effect profile. As the application of this therapy expands, awareness of its adverse events has also developed. The purpose of this review is to bring to light the side effects and complications associated with fecal microbiota transplantation, with an emphasis on findings from recently published studies.

Fecal microbiota transplantation (FMT) is being studied and utilized for various medical conditions including Clostridium difficile colitis, inflammatory bowel diseases (IBD), obesity, myasthenia gravis, and so on. Yet, FMT donation, whether from an individual or a stool bank, can be challenging given the numerous requirements and donor costs. Furthermore, data outcomes on recipients of FMT regarding donor's health co-morbidities, age, and weight are limited but emerging. The purpose of this review is to evaluate cost, safety, and accessibility in FMT donation.

Abstract
BACKGROUND AND OBJECTIVE Fat accumulation in the pancreas has remained a relatively unknown disease since it was initially described in 1926. However, it has gained increasing attention in the past two decades with the emergence of the obesity epidemic. Pancreatic steatosis is a general term used for fat accumulation in the pancreas. It is further classified into fatty replacement, fatty infiltration, lipomatous pseudo-hypertrophy, non-alcoholic fatty pancreas disease (NAFPD) and non-alcoholic fatty steatopancreatitis (NASP). NAFPD is defined as obesity-associated accumulation of fat in the pancreas without significant alcohol consumption. Data on the prevalence of NAFPD are limited due to a lack of standardized screening tests. METHODS MEDLINE/PubMed was searched to find relevant studies and abstracts on pancreatic steatosis. RESULTS Pancreatic fat can be quantified by various imaging techniques including ultrasonography, computed tomography, magnetic resonance imaging and magnetic resonance spectroscopy. The pathophysiology of NAFPD has not been completely understood. Chronic exposure of β-cells to hyperglycemia and higher levels of free fatty acids results in increased intracellular triglyceride accumulation, which ultimately causes reduced insulin secretion, insulin resistance, cell apoptosis and subsequent fatty replacement. This vicious cycle likely is a determining factor in the development of diabetes mellitus and metabolic syndrome. There is no approved pharmacologic therapy for NAFPD. Caloric restriction might have a role in normalization of β-cell function by reducing pancreatic fat content. Troglitazone (blend of telmisartan and sitagliptin) has demonstrated effectiveness in animal models but is still in experimental stages. CONCLUSION The cause and effect relationship between the metabolic syndrome and NAFPD has not yet been established. Further studies are required to study the effect of NAFPD on glucose hemostasis.

Abstract
BACKGROUND Sarcopenia, i.e., muscle loss is now a well-recognized complication of cirrhosis and in cases of non-alcoholic fatty liver disease can contribute to accelerate liver fibrosis leading to cirrhosis. Hence, it is imperative to study interventions which targets to improve sarcopenia in cirrhosis.
AIM To examine the relationship between interventions such nutritional supplementation, exercise, combined life style intervention, testosterone replacement and trans jugular intrahepatic portosystemic shunt (TIPS) to improve muscle mass in cirrhosis.
METHODS We search PubMed, EMBASE and Cochrane between June-August 2018, without a limiting period and the types of articles (RCTs, clinical trial, comparative study) in adult patients with sarcopenia and cirrhosis. The primary outcome of interest was improvement in muscle mass, strength and physical function interventions mentioned above. In the screening process, 154 full text articles were included in the review and 129 studies were excluded.
RESULTS We identified 24 studies that met review inclusion criteria. The studies were diverse in terms of the design, setting, interventions, and outcome measurements. We performed only qualitative synthesis of evidence due to heterogeneity amongst studies. Risk of bias was medium in most of the included studies and low quality of evidence showed improvement in the muscle mass, strength and physical function following aerobic exercise. 60% of the included studies on the nutritional intervention, 100% of the studies on testosterone replacement in hypogonadal men and trans-jugular portosystemic shunt were proved to be effective in improving sarcopenia in cirrhosis.
CONCLUSION Although the quality of evidence is low, the findings of our systematic review suggest improvement in the sarcopenia in cirrhosis with exercise, nutritional interventions, hormonal and TIPS interventions. High quality randomized controlled trials needed to further strengthen these findings.

Abstract
Patients with fistulizing inflammatory bowel disease are traditionally difficult to treat. This patient population often experiences delayed or insufficient healing of fistulas using current standard regimens including antibiotics, immunomodulators, anti-tumor necrosis factor-αdrug, placement of setons, and surgical repair. Several studies over the last ten to fifteen years have been conducted using stem cell therapies with promising results in this patient population. These studies show stem cell therapy in fistulizing disease to be successful in healing between 60%-88% compared to currently 50% with infliximab. Moreover, remission was seen 24 wk to 52 wk in these studies. Further research with a multi-approach treatment using medications, stem cell therapy, and surgical interventions will likely be the future of this innovative treatment approach.

Abstract
Diseases of the liver and biliary tree have been described with significant frequency among patients with human immunodeficiency virus (HIV), and its advanced state, acquired immunodeficiency syndrome (AIDS). Through a variety of mechanisms, HIV/AIDS has been shown to affect the hepatic parenchyma and biliary tree, leading to liver inflammation and biliary strictures. One of the potential hepatobiliary complications of this viral infection is AIDS cholangiopathy, a syndrome of biliary obstruction and liver damage due to infection-related strictures of the biliary tract. AIDS cholangiopathy is highly associated with opportunistic infections and advanced immunosuppression in AIDS patients, and due to the increased availability of highly active antiretroviral therapy, is now primarily seen in instances of poor access to anti-retroviral therapy and medication non-compliance. While current published literature describes well the clinical, biochemical, and endoscopic management of AIDS-related cholangiopathy, information on its epidemiology, natural history, and pathology are not as well defined. The objective of this review is to summarize the available literature on AIDS cholangiopathy, emphasizing its epidemiology, course of disease, and determinants, while also revealing an updated approach for its evaluation and management.

Abstract
Human hepatocyte transplantation is undergoing study as a bridge, or even alternative, to orthotopic liver transplantation (OLT). This technique has undergone multiple developments over the past thirty years in terms of mode of delivery, source and preparation of cell cultures, monitoring of graft function, and use of immunosuppression. Further refinements and improvements in these techniques will likely allow improved graft survival and function, granting patients higher yield from this technique and potentially significantly delaying need for OLT.

Abstract
The definitive treatment for end stage liver disease remains a liver transplant and hence livers are needed for these patients along with cases of acute fulminant liver failure. Hence livers are a scarce and highly valuable commodity in the current time. By extending the pool of donors to include the elderly livers, it allows for increased availability of donors and reduces the mortality that is associated with the waiting list itself. There is an increasing prevalence of end stage liver disease due to conditions like chronic hepatitis B and C, non-alcoholic steatohepatitis, alcoholic liver disease. Many studies show non-inferior outcomes when elderly livers are used as a vigorous selection process is implemented. The process takes into account the characteristics of the donor, graft and recipient allowing for appropriate donor-recipient coupling. To meet the increasing demands of livers, elderly donors should be utilized for liver transplantation. The aim of this review article is to describe the aging process of the liver and the outcomes associated with use of elderly livers for transplantation.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is well described as a common cause of chronic liver disease, mostly in the obese population. It refers to a spectrum of chronic liver disease that starts with simple steatosis than progresses to nonalcoholic steatohepatitis and cirrhosis in patients without significant alcohol consumption. NAFLD in the non-obese population has been increasingly reported and studied recently. The pathogenesis of nonobese NAFLD is poorly understood and is related to genetic predisposition, most notably patatin-like phospholipase domain-containing 33 G allele polymorphism that leads to intrahepatic triglyceride accumulation and insulin resistance. Non-obese NAFLD is associated with components of metabolic syndrome and, especially, visceral obesity which seems to be an important etiological factor in this group. Dietary factors and, specifically, a high fructose diet seem to play a role. Cardiovascular events remain the main cause of mortality and morbidity in NAFLD, including in the non-obese population. There is not enough data regarding treatment in non-obese NAFLD patients, but similar to NAFLD in obese subjects, lifestyle changes that include dietary modification, physical activity, and weight loss remain the mainstay of treatment.

Abstract
Hepatitis C virus (HCV) which was originally recognized as posttransfusion non-A, non-B hepatitis has been a major global health problem affecting 3% of the world population. Interferon/peginterferon and ribavirin combination therapy was the backbone of chronic HCV therapy for two decades of the journey. However, the interferon based treatment success rate was around 50% with many side effects. Many chronic HCV patients with psychiatric diseases, or even cytopenias, were ineligible for HCV treatment. Now, we no longer need any injectable medicine. New direct-acting antiviral agents against HCV allowed the advance of interferon-free and ribavirin-free oral regimens with high rates of response and tolerability. The cost of the medications should not be a barrier to their access in certain parts of the world. While we are getting closer, we should still focus on preventing the spread of the disease, screening and delivering the cure globally to those in need. In the near future, development of an effective vaccine against HCV would make it possible to eradicate HCV infection worldwide completely.

Abstract
Coffee has long been recognized as having hepatoprotective properties, however, the extent of any beneficial effect is still being elucidated. Coffee appears to reduce risk of hepatocellular carcinoma, reduce advancement of fibrotic disease in a variety of chronic liver diseases, and perhaps reduce ability of hepatitis C virus to replicate. This review aims to catalog the evidence for coffee as universally beneficial across a spectrum of chronic liver diseases, as well as spotlight opportunities for future investigation into coffee and liver disease.

Abstract
BACKGROUND & AIMS Hepatocyte transplantation partially corrects genetic disorders and has been associated anecdotally with reversal of acute liver failure. Monitoring for graft function and rejection has been difficult, and has contributed to limited graft survival. Here we aimed to use preparative liver-directed radiation therapy, and continuous monitoring for possible rejection in an attempt to overcome these limitations. METHODS Preparative hepatic irradiation was examined in non-human primates as a strategy to improve engraftment of donor hepatocytes, and was then applied in human subjects. T cell immune monitoring was also examined in human subjects to assess adequacy of immunosuppression. RESULTS Porcine hepatocyte transplants engrafted and expanded to comprise up to 15% of irradiated segments in immunosuppressed monkeys preconditioned with 10Gy liver-directed irradiation. Two patients with urea cycle deficiencies had early graft loss following hepatocyte transplantation; retrospective immune monitoring suggested the need for additional immunosuppression. Preparative radiation, anti-lymphocyte induction, and frequent immune monitoring were instituted for hepatocyte transplantation in a 27year old female with classical phenylketonuria. Post-transplant liver biopsies demonstrated multiple small clusters of transplanted cells, multiple mitoses, and Ki67+ hepatocytes. Mean peripheral blood phenylalanine (PHE) level fell from pre-transplant levels of 1343±48μM (normal 30-119μM) to 854±25μM (treatment goal ≤360μM) after transplant (36% decrease; p<0.0001), despite transplantation of only half the target number of donor hepatocytes. PHE levels remained below 900μM during supervised follow-up, but graft loss occurred after follow-up became inconsistent. CONCLUSIONS Radiation preconditioning and serial rejection risk assessment may produce better engraftment and long-term survival of transplanted hepatocytes. Hepatocyte xenografts engraft for a period of months in non-human primates and may provide effective therapy for patients with acute liver failure. LAY SUMMARY Hepatocyte transplantation can potentially be used to treat genetic liver disorders but its application in clinical practice has been impeded by inefficient hepatocyte engraftment and the inability to monitor rejection of transplanted liver cells. In this study, we first show in non-human primates that pretreatment of the host liver with radiation improves the engraftment of transplanted liver cells. We then used this knowledge in a series of clinical hepatocyte transplants in patients with genetic liver disorders to show that radiation pretreatment and rejection risk monitoring are safe and, if optimized, could improve engraftment and long-term survival of transplanted hepatocytes in patients.

Abstract
Hepatitis C virus (HCV) is a global pandemic, with nearly 200 million infected patients worldwide. HCV is the most common blood-borne infection in the US with numerous health implications including liver fibrosis, cirrhosis, and hepatocellular cancer. Traditional genotype-based HCV therapies with interferon resulted in moderate success in the sustained elimination of viral genome. Recent clinical trials of the once-daily combination tablet of sofosbuvir, a nonstructural (NS) 5B polymerase inhibitor, and velpatasvir, an NS5A inhibitor, demonstrate sustained virologic response rates of about 95%, regardless of prior treatment experience or presence of cirrhosis across all HCV genotypes. Patients reported improvements in general health, fatigue, and emotional and mental well-being after completing combination therapy. The combination treatment is effective, but does need to be administered with caution in patients receiving certain medications or with certain diseases. Herein, we review the safety and efficacy of sofosbuvir/velpatasvir combination regimen for all HCV genotypes.

Abstract
Infliximab is a monoclonal antibody that antagonizes the activity of tumor necrosis factor alpha to induce and maintain remission in patients with inflammatory bowel disease. Adverse effects associated with Infliximab infusions include infusion reactions, risk of infections, development of hematological malignancies, and pancytopenia. Autoimmune hemolytic anemia has rarely been reported in ulcerative colitis. Herein we report a case of drug-induced hemolytic anemia after infliximab infusion for treating ulcerative colitis.
