Bowel Perforation Caused by Biliary Stent Migration After ERCP: A Systematic Review.

GOALS: This systematic review aims to evaluate the risk factors, clinical features, and outcomes of bowel perforation caused by stent migration after endoscopic retrograde cholangiopancreatography (ERCP). BACKGROUND: Distal migration of biliary stents can occur after ERCP. Upon migration, most stents pass through the intestine without adverse events; however, bowel perforation has been reported. STUDY: A comprehensive literature search of PubMed, EMBASE, and Cochrane databases was conducted through October 2023 for articles that reported bowel perforation because of stent migration. Cases of incomplete stent migration and proximal stent migration were excluded. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines to identify full-length articles in English reporting. RESULTS: Of 2041 articles retrieved on the initial search, 92 met the inclusion criteria. A total of 132 cases of bowel perforation occurred due to stent migration after ERCP (56.1% female; average age: 66 y). The median time from initial ERCP to perforation was 44.5 days (IQR 12.5-125.5). Most cases of perforation occurred in the small bowel (64.4%) compared with the colon (34.8%). Stents were mostly plastic (87.1%) with a median diameter of 10 Fr (IQR 8.5-10) and median length of 10.3 cm (IQR 715). Surgical management was pursued in 52.3% and endoscopic management in 42.4%. Bowel resection was required for 25.8% of patients. The overall mortality rate was 17.4%. CONCLUSION: In summary, this study demonstrates that bowel perforation after ERCP stent migration primarily occurs within 44.5 days and most frequently with a 10 Fr plastic biliary stent. The overall mortality rate was 17.4%. It is important for endoscopists to be mindful of this rare but serious adverse event.

Critical care outcomes in decompensated cirrhosis: a United States national inpatient sample cross-sectional study.

BACKGROUND: Prior assessments of critical care outcomes in patients with cirrhosis have shown conflicting results. We aimed to provide nationwide generalizable results of critical care outcomes in patients with decompensated cirrhosis. METHODS: This is a retrospective study using the National Inpatient Sample from 2016 to 2019. Adults with cirrhosis who required respiratory intubation, central venous catheter placement or both (n = 12,945) with principal diagnoses including: esophageal variceal hemorrhage (EVH, 24%), hepatic encephalopathy (58%), hepatorenal syndrome (HRS, 14%) or spontaneous bacterial peritonitis (4%) were included. A comparison cohort of patients without cirrhosis requiring intubation or central line placement for any principal diagnosis was included. RESULTS: Those with cirrhosis were younger (mean 58 vs. 63 years, p < 0.001) and more likely to be male (62% vs. 54%, p < 0.001). In-hospital mortality was higher in the cirrhosis cohort (33.1% vs. 26.6%, p < 0.001) and ranged from 26.7% in EVH to 50.6% HRS. Mortality when renal replacement therapy was utilized (n = 1580, 12.2%) was 46.5% in the cirrhosis cohort, compared to 32.3% in other hospitalizations (p < 0.001), and was lowest in EVH (25.7%) and highest in HRS (51.5%). Mortality when cardiopulmonary resuscitation was used was increased in the cirrhosis cohort (88.0% vs. 72.1%, p < 0.001) and highest in HRS (95.7%). CONCLUSIONS: One-third of patients with cirrhosis requiring critical care did not survive to discharge in this U.S. nationwide assessment. While outcomes were worse than in patients without cirrhosis, the results do suggest better outcomes compared to previous studies.

Microbiological and clinical characteristics of invasive Group B Streptococcal blood stream infections in children and adults from Qatar.

INTRODUCTION: Group B Streptococci (GBS) colonize almost one third of human gastrointestinal and genitourinary tracts, particularly in females. The aim of this study is to evaluate the epidemiology, microbiological characteristics, and clinical outcomes of invasive GBS disease in Qatar from all age groups. METHODS: A retrospective study was conducted on patients with confirmed GBS blood stream infections during the period between January 2015 and March 2019. Microbiological identification was performed using automated BD PhoenixTM system, while additional antimicrobial susceptibility tests were performed using E test and disc diffusion methods. RESULT: During the four years period, the incidence steadily rose from 1.48 to 2.09 cases per 100.000 population. Out of 196 confirmed cases of invasive GBS infections, the majority were females (63.7%, 125/196) of which 44.8% were pregnant and 53.6% were colonized. Three distinct affected age groups were identified: children ≤ 4 years of age (35.7%), young adults 25-34 (20.9%) and the elderly ≥ 65 year (17.4%). Presenting symptoms were mild with fever in 53% of cases while 89% of cases had Pitt bacteraemia score of ≤ 2. Isolates were universally sensitive to penicillin, ceftriaxone, and vancomycin at 100% but with significant resistance to erythromycin (49%) and clindamycin (28.6%) while 16.8% had inducible clindamycin resistance. Clinical outcomes showed cure rate of 87.25% with complications in (8.76%) and 4% mortality. CONCLUSION: There is a rising trend of Group B Streptococcal blood stream infections in Qatar with significantly high clindamycin and erythromycin resistance rates. Universal susceptibility rates were demonstrated for penicillin, ceftriaxone, and vancomycin.

Pancreatic Tuberculosis With Duodenal Fistula Presenting as Life-Threatening Gastrointestinal Bleeding.

Pancreatic tuberculosis (TB) warrants heightened suspicion in individuals with pancreatic lesions and risk factors such as HIV, organ transplantation, or pertinent immigration history. We present a 38-year-old man who presented with hemodynamically unstable gastrointestinal bleeding. He was found to have pancreatic TB complicated by a duodenal ulcer with fistula. Following 1 month of antitubercular therapy, he experienced complete resolution of symptoms, healing of the duodenal ulcer, closure of the fistulous tract, and a decrease in the size of the pancreatic lesion as observed on imaging. Our case highlights the importance of early diagnosis and treatment of pancreatic TB.

Outcomes of Liver Transplant Recipients Hospitalized With COVID-19: A Nationwide Analysis From the United States.

Introduction: Currently available data regarding the impact of liver transplantation on the outcomes of patients hospitalized with COVID-19 is conflicting. This study aims to compare the outcomes and resource utilization between patients with and without a history of liver transplant hospitalized with COVID-19. Methods and materials: This is a retrospective study using the National Inpatient Sample. All adults hospitalized with COVID-19 in the year 2020 were included. Mortality was the primary outcome, while endotracheal intubation, length of hospital stay, and total hospital charges were the secondary outcomes. Results: Out of 1,050,720 adults admitted with COVID-19 as the primary diagnosis, 1,455 had a secondary diagnosis of liver transplant. Mortality was not significantly increased in transplant recipients (OR adjusted = 0.69, 95% CI: 0.46-1.03, P = 0.07). Intubation rates and total hospital charges did not differ significantly between liver transplant recipients and patients without a history of liver transplant receipt. LOS was shorter by a coefficient of almost two days in patients with a history of LT (P < 0.001). Conclusion: Liver transplant recipients do not appear to be at increased risk of severe COVID-19 and COVID-19 mortality.

Terlipressin-induced skin necrosis in cirrhotic patients-A case report and comprehensive literature review.

Key Clinical Message: The occurrence of terlipressin-induced skin necrosis in cirrhotic patients is a rare but serious adverse event that warrants further investigation. Clinicians should be aware of this potential complication in cirrhotic patients receiving terlipressin therapy and closely monitor for any signs of skin necrosis. Early recognition and prompt intervention are crucial in preventing further complications and improving patient outcomes. Further research is needed to better understand the risk factors associated with terlipressin-induced skin necrosis and to develop effective preventive strategies. Overall, healthcare providers should exercise caution when prescribing terlipressin to cirrhotic patients, weighing the potential benefits against the risks of this rare but significant adverse event. Abstract: Terlipressin is commonly used to manage conditions related to portal hypertension, such as hepatorenal syndrome and esophageal variceal bleeding. Despite its therapeutic benefits, terlipressin can rarely lead to severe ischemic complications involving the skin vasculature, known as terlipressin-induced skin necrosis. We present a 50-year-old male with cirrhosis and acute variceal bleeding who developed skin necrosis following terlipressin administration. We performed a comprehensive review of the literature by analyzing 18 case reports/case series comprising 22 cirrhotic patients with terlipressin-induced skin necrosis. Among these individuals, we found a mean age of 51 years with a male predominance (78%). Further analysis showed that the onset of skin necrosis ranged from 2 to 5 days post-terlipressin initiation, with bolus administration being predominant (85.7%). The underlying pathophysiological mechanisms of terlipressin-induced skin ischemia are still elusive but primarily attributed to the vasoconstrictive and thrombogenic effects. Management involves terlipressin discontinuation and supportive care. Physicians should be aware of this potential complication in patients receiving terlipressin and closely observe for any signs of skin rash.

Risk of Aspiration Pneumonitis After Elective Esophagogastroduodenoscopy in Patients on Glucagon-Like Peptide-1 Receptor Agonists.

Background Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are gaining popularity in the management of diabetes mellitus and obesity. It has been suggested that this class of medications causes delayed gastric emptying which raised concerns about the potential for aspiration of gastric contents in patients undergoing sedation. This led to a statement by the American Society of Anesthesiologists about their preoperative use. Nevertheless, there is minimal evidence regarding the effects of GLP-1RAs on the risk of aspiration post-esophagogastroduodenoscopy (EGD). In this study, we sought to evaluate the incidence of aspiration and pneumonia in patients receiving GLP-1RAs who underwent EGD. Methodology We performed a retrospective cohort study in TriNetX, a global federated research network of electronic health records. The primary outcome was the development of aspiration post-EGD. Secondary outcomes were the development of aspiration pneumonia and requiring antibiotics post-EGD. One-to-one propensity score matching was performed for age, sex, diabetes mellitus, obesity, and other comorbidities between the cohorts. Results Our analysis showed a small but significant risk of aspiration pneumonitis in patients on GLP-1RAs undergoing elective EGD compared to non-GLP-1RA-receiving patients. However, there was no increased risk of the composite outcome of respiratory failure or intensive care unit (ICU) admission; however, this did not reach statistical significance. Conclusions GLP-1RA use was associated with an increased risk of aspiration in patients undergoing elective upper endoscopy. However, this did not translate to an increased risk of respiratory failure or ICU admission. Our findings highlight the importance of following an individualized approach to preoperative management that takes into consideration GLP-1RA indications and other aspiration risk factors, including advanced age, impaired gag reflex, and gastrointestinal symptoms such as nausea and abdominal distention.

The utility of testing erythropoietin level in polycythemia diagnosis.

OBJECTIVES: Polycythemia vera (PV) is classically thought to be associated with low erythropoietin (EPO) levels. Here, we present a review of the utility of using EPO levels in diagnosing polycythemia. METHODS: We conducted a systematic literature review of the Medline data through Pubmed and Google Scholar. We included the articles which described confirmed PV associated with elevated EPO level. Our search strategy included the following terms in Pubmed (((polycythemia vera[MeSH Terms]) OR (jak2 protein tyrosine kinase[MeSH Terms])) OR (Myeloproliferative Disorders[MeSH Terms])) AND (Erythropoietin[MeSH Terms]), and 'polycythemia vera with erythropoietin' in Google Scholar. RESULTS: Our research yielded four cases of PV with elevated EPO levels. The most common symptom was a headache. Thrombotic phenomena happened in a single case in the form of Budd-Chiari syndrome. The mean Hb level was 20.2 gm/dl, and the EPO level was 213 mlU/mL. DISCUSSION: Although PV is usually associated with low EPO levels, high levels do not exclude this diagnosis. Workup should include testing for JAK2 mutation and bone marrow biopsy in the presence of suggestive signs and symptoms. Novel biomarkers are also being proposed to aid in the diagnosis. CONCLUSION: Although elevated EPO levels suggest secondary causes of polycythemia, cases where elevated EPO levels were associated with an underlying PV are reported in the literature, and we have summarized a review of them. Workup for polycythemia should include JAK2 mutation testing if signs and symptoms suggest PV even if EPO is elevated.

The Outcome of Fatherhood in Patients With Philadelphia-Negative Myeloproliferative Neoplasms: A Single-Institution Experience.

Background Fertility is a highly complex subject; it involves more than one individual and has profound psychological and economic implications. Moreover, it is affected by several factors, including age, significant systemic illness in either partner, exposure to environmental toxins, medications, or radiation. In patients with malignancy, fertility is more complicated. Patients with a malignancy might have reduced fertility due to the disease, medication, and radiation. Besides the reduced fertility, there are more concerns regarding the subsequent effect of cancer treatment on their offspring and the possibility of having healthy children. There were many studies regarding fertility in patients with cancer; however, in male patients with Philadelphia-negative myeloproliferative neoplasms (MPNs), there are very limited data. Objectives In this study, we aim to see the outcome of fatherhood in male patients with Philadelphia-negative myeloproliferative neoplasms (MPNs), polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) whether on treatment or not. Methods A retrospective mixed-design study of male patients with Philadelphia-negative MPN was followed up in our institute (National Center for Cancer Care and Research (NCCCR)), Doha, Qatar, between January 1, 2008, and January 1, 2020. Patients were interviewed regarding fertility-related information. All included patients had a confirmed diagnosis of Philadelphia-negative MPN according to World Health Organization (WHO) 2008 or WHO 2016 criteria for MPN, aged more than 18 years old. Results A total of 124 male patients were interviewed, and only 20 patients met the inclusion criteria. The majority of the patients were lost to follow-up or could not be contacted, and 28.8% of the excluded patients had their families completed by the time of diagnosis. The treatment received included hydroxycarbamide (n=8), pegylated interferon 2 alpha (n=10), ruxolitinib (n=1), and phlebotomy (n=1). The mean duration of exposure to treatment before pregnancy was 4.7 years. The mode of delivery was normal vaginal delivery in 71.4% of the pregnancies. The total number of offspring was 30, and the total number of conceptions was 30. Conclusion Our data showed that most Philadelphia-negative MPN male patients on treatment had their offspring born normally with no serious complications, congenital anomalies, or reports of MPN-related cancers. Patients' concerns regarding fertility should be addressed well to ensure a better quality of life.

Electronic Cigarette or Vaping Product Use-Associated Lung Injury in a Previously Healthy Young Male.

Vaping (i.e., the use of electronic cigarettes) has been gaining popularity among people for the past few years, perhaps due to the misconception that its use is less harmful than traditional cigarettes. Although the long-term effects of these products are still unknown, it has been shown that they can be implicated in acute lung injury in healthy people. In 2019, an epidemic of severe acute lung injury was reported in the United States, and it was linked to vaping or electronic cigarette use and was referred to as e-cigarette or vaping product use-associated lung injury (EVALI). Here, we present the first case of EVALI in the state of Qatar.

Nilotinib-Induced Diabetes Mellitus in a Young Female with Chronic Myeloid Leukemia.

Chronic myeloid leukemia (CML) is one of the myeloproliferative neoplasms whose incidence peaks in older individuals and is characterized by the uncontrolled proliferation of cells in the myeloid cell line. It can present with symptoms related to leukocytosis or splenomegaly, and it can also be asymptomatic and found incidentally. Nilotinib is a second-generation tyrosine kinase inhibitor used in the treatment of the chronic phase of CML and was found to cause diabetes mellitus among other adverse effects. These adverse effects seem to occur after a few months to a few years of drug administration. Type-two diabetes is the most common type of diabetes; its hallmark being insulin resistance with resultant hyperglycemia. Most often, it has no symptoms and is usually found as an incidental finding or on screening. Here we present a 45-year old Chinese female, who was diagnosed with CML chronic phase after an incidental finding of leukocytosis; treated with nilotinib as upfront for CML, and developed diabetes mellitus after about one and a half years of treatment, which was treated with metformin.
