Patient: Female, 87 Final Diagnosis: Acquired hemophilia A Symptoms: Chest discomfort • shortness of breath Medication: — Clinical Procedure: — Specialty: Hematology Objective: Unusual setting of medical care Background: Acquired hemophilia A (AHA) is a rare hemorrhagic disorder that is caused by producing autoantibodies against factor VIII. It is usually characterized by severe, spontaneous bleeding, which can be life-threatening. The current standard treatments for bleeding prophylaxis are highly effective but accompanied with some disadvantages such as frequent intravenous infusions, high cost, and risk of thromboembolic complications. Emicizumab is a bispecific antibody with a therapeutic FVIII-mimetic nature. Emicizumab has shown a reduction in annualized bleeding rate in congenital hemophilia patients with and without inhibitors. The pathophysiological concepts and preclinical data suggest that Emicizumab can be effectively used for treating AHA. Case Report: We present the case of an 87-year-old woman admitted for symptomatic anemia and large chest wall and pelvic hematomas confirmed by imaging, without history of trauma. Her coagulation studies showed isolated prolonged activated partial thromboplastin time (aPTT), low factor VIII activity level, and high levels of factor VIII inhibitor. She was successfully treated with activated prothrombin complex concentrate (aPCC), which was transitioned to Emicizumab on discharge. No recurrent bleeding episodes or adverse events related to Emicizumab were reported during the 2-month follow-up period. Conclusions: A subcutaneous weekly or biweekly injection of Emicizumab, a recombinant monoclonal antibody, offers several advantages: less frequent infusions, good hemostatic efficacy, possible outpatient therapy, and even more cost-effective than bypassing agents. More clinical studies should be conducted to compare Emicizumab with the current standards of care.
Background Coronavirus disease-2019 (COVID-19) is a global pandemic. Obesity has been associated with increased disease severity in COVID-19, and obesity is strongly associated with hepatic steatosis (HS). However, how HS alters the natural history of COVID-19 is not well characterized, especially in Western populations. Aims To characterize the impact of HS on disease severity and liver injury in COVID-19. Methods We examined the association between HS and disease severity in a single-center cohort study of hospitalized COVID-19 patients at Michigan Medicine. HS was defined by either hepatic steatosis index > 36 (for Asians) or > 39 (for non-Asians) or liver imaging demonstrating steatosis > 30 days before onset of COVID-19. The primary predictor was HS. The primary outcomes were severity of cardiopulmonary disease, transaminitis, jaundice, and portal hypertensive complications. Results In a cohort of 342 patients, metabolic disease was highly prevalent including nearly 90% overweight. HS was associated with increased transaminitis and need for intubation, dialysis, and vasopressors. There was no association between HS and jaundice or portal hypertensive complications. In a sensitivity analysis including only patients with liver imaging > 30 days before onset of COVID-19, imaging evidence of hepatic steatosis remained associated with disease severity and risk of transaminitis. Conclusions HS was associated with increased disease severity and transaminitis in COVID-19. HS may be relevant in predicting risk of complications related to COVID-19.
Introduction Annually, 500,000 episodes of alcohol withdrawal syndrome (AWS) are severe enough to require clinical attention. A symptom-triggered lorazepam regimen remains the standard of care for the management of hospitalized AWS patients. However, phenobarbital has also been shown to be an effective adjunctive therapy for severe AWS, reducing benzodiazepine use in the emergency department (ED) and the intensive care unit (ICU). The purpose of this study is to compare hospital length of stay (LOS) for AWS patients using phenobarbital-based versus lorazepam-based treatment protocols as monotherapy for management of AWS on general medical units. Methods This is a retrospective cohort study over a two-year period (March, 2016 to March, 2018), conducted at three hospitals within the St. Joseph Mercy Health System. We included 606 patients with a primary diagnosis of AWS or alcohol intoxication who met our inclusion criteria (543 in the lorazepam cohort and 63 in the phenobarbital cohort). Adjusted comparisons were done using propensity scoring methods. Hospital LOS was set as the primary outcome. Secondary outcomes included all-cause 30-day readmission, alcohol-related 30-day readmission, 30-day ED visits after discharge, and need for ICU transfer during hospital stay. Results Patients who received phenobarbital had a statistically significant shorter hospital LOS as compared to patients who received lorazepam (2.8 versus 3.6 days, P < 0.001). Furthermore, the phenobarbital treatment group had statistically significant lower rates of all-cause 30-day readmission (11.11% versus 14.18%, P = 0.020) and 30-day ED visits after discharge (11.11% versus 18.6%, P = 0.015). No statistical significance was detected for alcohol-related 30-day readmission and the need for ICU transfer between the treatment groups. Conclusion This study suggests that phenobarbital may be a reasonable alternative to lorazepam in the management of AWS patients admitted to general medical units. Larger scale, well-executed, and adequately powered prospective studies and randomized controlled trials are needed to corroborate these findings.
Background Abdominal pain is a debilitating symptom affecting ∼80% of pancreatic cancer (PC) patients. Pancreatic duct (PD) decompression has been reported to alleviate this pain, although this practice has not been widely adopted. We aimed to evaluate the role, efficacy, and safety of endoscopic PD decompression for palliation of PC post-prandial obstructive-type pain. Methods A systematic review until 7 October 2020 was performed. Two independent reviewers selected studies, extracted data, and assessed the methodological quality. Results We identified 12 publications with a total of 192 patients with PC presenting with abdominal pain, in whom PD decompression was attempted, and was successful in 167 patients (mean age 62.5 years, 58.7% males). The use of plastic stents was reported in 159 patients (95.2%). All included studies reported partial or complete improvement in pain levels after PD stenting, with an improvement rate of 93% (95% confidence interval, 79%–100%). The mean duration of pain improvement was 94 ± 16 days. Endoscopic retrograde cholangiopancreatography (ERCP)-related adverse events (AEs) were post-sphincterotomy bleeding (1.8%), post-ERCP pancreatitis (0.6%), and hemosuccus pancreaticus (0.6%). AEs were not reported in two patients who underwent endoscopic ultrasound-guided PD decompression. In the 167 patients with technical success, the stent-migration and stent-occlusion rates were 3.6% and 3.0%, respectively. No AE-related mortality was reported. The methodological quality assessment showed the majority of the studies having low or unclear quality. Conclusion In this exploratory analysis, endoscopic PD drainage may be an effective and safe option in selected patients for the management of obstructive-type PC pain. However, a randomized–controlled trial is needed to delineate the role of this invasive practice.
Background Spontaneous hyperinflation is reported to the Food and Drug Administration as a complication of intragastric balloons. It is postulated that orogastric contamination of the intragastric balloon may cause this phenomenon. We sought to investigate the effects of intentional balloon contamination with gastric contents on intragastric balloon perimeter and contents, whether methylene blue plays a role in preventing spontaneous hyperinflation, and review the available literature on spontaneous hyperinflation. Methods Four pairs of balloons with different combinations of sterile saline, orogastric contaminants, and methylene blue were incubated in a 37 °C water bath for six months to simulate physiological conditions with serial measurements of balloon perimeter. Our findings were compared against a systematic review across multiple databases to summarize the available literature. Results Balloon mean perimeter decreased from 33.5 cm ± 0.53 cm to 28.5 cm ± 0.46 cm (p < 0.0001). No significant differences were seen with the methylene blue group. Only 11 cases were found reported in the literature. Conclusions Despite contaminating intragastric balloons with gastric aspirates, hyperinflation did not occur, and other factors may be in play to account for this phenomenon, when observed. Rates of hyperinflation remain under-reported in the literature. Further controlled experiments are needed.
Adenomas or adenocarcinomas located within a colonic diverticulum are considered a rare phenomenon that has been described in the literature. These lesions are technically difficult to manage endoscopically and usually require surgical intervention for removal. There is also an increased risk of perforation upon endoscopic resection owing to the lack of a muscular layer within the diverticulum. We report a case and include a literature review to evaluate different endoscopic techniques and propose the most effective for management of adenomas within a diverticulum. This technique is potentially comprised of employing a combined approach using a suction banding device, an over-the-scope clip (OTSC; Ovesco Endoscopy AG, Tübingen, Germany) , and hyperthemic snare to successfully remove the polyp, ensure tissue retrieval, and reduce risk of iatrogenic colonic perforation.
