Efficacy and Safety of Remdesivir in People With Impaired Kidney Function Hospitalized for COVID-19 Pneumonia: A Randomized Clinical Trial.

BACKGROUND: Few antiviral therapies have been studied in patients with COVID-19 and kidney impairment. Herein, efficacy, safety, and pharmacokinetics of remdesivir, its metabolites, and sulfobutylether-beta-cyclodextrin excipient were evaluated in hospitalized patients with COVID-19 and severe kidney impairment. METHODS: In REDPINE, a phase 3, randomized, double-blind, placebo-controlled study, participants aged ≥12 years hospitalized for COVID-19 pneumonia with acute kidney injury (AKI), chronic kidney disease (CKD), or kidney failure were randomized 2:1 to receive intravenous remdesivir (200 mg on Day 1; 100 mg daily up to Day 5) or placebo (enrollment: March 2021-March 2022). The primary efficacy endpoint was the composite of all-cause mortality or invasive mechanical ventilation (IMV) through Day 29. Safety was evaluated through Day 60. RESULTS: Although enrollment concluded early, 243 participants were enrolled and treated (remdesivir, n = 163; placebo, n = 80). At baseline, 90 (37.0%) participants had AKI (remdesivir, 60; placebo, 30), 64 (26.3%) had CKD (remdesivir, 44; placebo, 20), and 89 (36.6%) had kidney failure (remdesivir, 59; placebo, 30); 31 (12.8%) were COVID-19 vaccinated. Composite all-cause mortality or IMV through Day 29 was 29.4% and 32.5% in the remdesivir and placebo group, respectively (P = 0.61). Treatment-emergent adverse events were reported in 80.4% versus 77.5% and serious adverse events in 50.3% versus 50.0% of participants who received remdesivir versus placebo, respectively. Pharmacokinetic plasma exposure to remdesivir was not affected by kidney function. CONCLUSIONS: Although underpowered, no significant difference in efficacy was observed between treatment groups. REDPINE demonstrated that remdesivir is safe in those with COVID-19 and severe kidney impairment. (EudraCT number: 2020-005416-22; Clinical Trials.gov number: NCT04745351).

Factors That Influence the Speed and Completion of Double Balloon Enteroscopy in Patients with Arteriovenous Malformations.

BACKGROUND: Double balloon enteroscopy remains a resource and time-intensive procedure that is not available in many endoscopy units. AIMS: We aimed to identify variables impacting the speed and completion of double balloon enteroscopy. METHODS: We retrospectively reviewed 550 patients. Using a mean time and distance for both the antegrade and retrograde approach, we determined the procedure speed and assessed factors that influenced it. In addition, we assessed the factors that contributed to a complete double balloon enteroscopy. RESULTS: A total of 386 antegrade and 164 retrograde double balloon enteroscopies were performed. Greater than 10 AVMs requiring treatment was a negative predictor (AOR 0.25, CI 0.11-0.51, p < 0.001), whereas age greater than 60 years (AOR 2.66, CI 1.18-6.65, p = 0.025) was a positive predictor of a fast antegrade enteroscopy. For retrograde, prior abdominal surgery was the only factor that trended to significance (AOR 0.38, CI 0.14-0.99, p = 0.052). A total of 120 combined procedures were performed. Female gender (AOR 2.62, CI 1.16-6.24, p = 0.02), history of prior abdominal surgery (AOR 0.31, CI 0.13-0.70, p = 0.006) and Boston bowel pre-preparation score of greater than 6 (AOR 4.50, CI 1.59-14.30, p = 0.006) were the only significant predictors of a complete procedure. CONCLUSION: By applying double balloon enteroscopy speed, a novel method of measuring procedure efficiency, we were able to more reliably identify the factors that will negatively impact the speed and success of the procedure.

Clinical Characteristics and Computed Tomography Findings in Adult Patients With an Aberrant Right Subclavian Artery: A Single-Center Retrospective Cohort Study.

OBJECTIVE: We sought to determine the prevalence and possible features associated with symptoms in adult patients diagnosed with an aberrant right subclavian artery (ARSA). METHODS: In this single-center retrospective study, 386 adult patients were diagnosed with ARSA on chest CT scans performed between June 2016 and April 2021. Patients were grouped by the presence of symptoms, which included dysphagia, shortness of breath, cough, and upper airway wheezing. Four cardiothoracic radiologists reviewed the chest CT scans to assess features of ARSA. Agreement and multivariable logistic regression analyses were performed to determine interobserver variability and features associated with the presence of symptoms, respectively. RESULTS: The prevalence of ARSA was 1.02% and 81.3% of patients were asymptomatic. Shortness of breath (74.6%) was the most common symptom. Interobserver agreement was acceptable with most variables having an interclass correlation coefficient or κ >0.80. A patient's height > 158 cm (OR: 2.50, P = 0.03), cross-sectional area > 60 mm 2 of ARSA at the level of the esophagus (OR: 2.39, P = 0.046), and angle >108 degrees formed with the aortic arch (OR: 1.99, P = 0.03) were associated with the presence of symptoms on multivariable logistic regression. A distance increase per 1 mm between ARSA and trachea (OR: 0.85, P = 0.02) was associated with decreased odds of symptoms. CONCLUSIONS: Aberrant right subclavian artery is an incidental finding in most adult patients. The cross-sectional area at the level of the esophagus, angle formed with the medial wall of the aortic arch, distance between the ARSA and the trachea, and a patient's height were features associated with the presence of symptoms.

Exocrine pancreatic insufficiency after bariatric surgery.

BACKGROUND: Exocrine pancreatic insufficiency (EPI) is a known complication of upper gastrointestinal surgery and has recently been associated with bariatric surgery. Our objectives were to determine the incidence of EPI in patients who underwent bariatric surgery and to identify the type of bariatric procedure most associated with EPI. METHODS: This retrospective cohort analysis included patients age ≥18 years who underwent bariatric surgery at Mayo Clinic between 2010 and 2020. Patients with a history of other gastrointestinal or hepatobiliary resection, revision of bariatric surgery, EPI prior to surgery, and surgery greater than >10 years earlier were excluded from the study. Characteristics were compared between two groups based on type of bariatric surgery including Roux-en-Y gastric bypass (RYGB) or gastric sleeve (GS). Characteristics were also analyzed between patients with RYGB who developed post-operative steatorrhea and those who did not. RESULTS: Of 150 patients, 126 underwent RYGB while 24 patients had GS. Thirty-one (20.6%) patients developed post-operative steatorrhea and 14 (9.3%) were diagnosed with EPI. Mean pancreatic elastase level was 287 ± 156 mcg/g and fecal fat level 31 ± 22 g/d. There was a significantly higher proportion of post-operative steatorrhea in patients who underwent RYGB compared to gastric sleeve surgery (p = 0.029). CONCLUSION: The incidence of EPI after bariatric surgery in our cohort was 9.3%. Overall, patients who underwent RYGB had higher rates of EPI (10.3%) than those who had GS (4.2%). Clinicians should be aware of EPI as a cause for steatorrhea in patients who underwent bariatric surgery and consider treatment with enzyme replacement therapy.

Abnormal findings on abdominopelvic cross-sectional imaging in patients with microscopic colitis: a retrospective, multicenter study.

OBJECTIVES: Patients with microscopic colitis may have subtle macroscopic findings on colonoscopy such as erythema, edema, or altered vascular pattern; however, radiographic abnormalities on cross-sectional imaging have not been investigated. We aimed at identifying the abdominopelvic radiographic abnormalities in patients with microscopic colitis, as well as possible correlation with endoscopic findings and the need for extended duration of treatment. MATERIALS AND METHODS: This was a retrospective study of patients with biopsy-proven microscopic colitis at two tertiary centers between 1 January 2010 and 30 April 2020. Patients underwent computed tomography scan or magnetic resonance imaging within 30 days of a diagnostic flexible sigmoidoscopy or colonoscopy. Patients with colon ischemia and other causes of colitis were excluded. Radiographic abnormalities from imaging reports included bowel wall thickening, mucosal hyperenhancement and mesenteric fat stranding. Univariate and multivariable logistic regression models were used to identify predictors of radiographic abnormalities. RESULTS: 498 patients with microscopic colitis underwent abdominopelvic cross-sectional imaging within 30 days of flexible sigmoidoscopy/colonoscopy. Lymphocytic colitis was diagnosed in 54.6% of patients, and collagenous colitis in 45.4%. Endoscopic and radiographic abnormalities were identified in 16.1% and 12.4% of patients, respectively. Radiographic abnormalities were associated with the need for budesonide therapy (p = .029) and budesonide therapy long-term (p = .0028). Budesonide therapy long-term (p = .047) was associated with radiographic abnormalities in multivariate analysis. CONCLUSIONS: Radiographic abnormalities may be present on abdominopelvic cross-sectional imaging in a minority of patients with biopsy-proven microscopic colitis, suggesting cross-sectional imaging has low clinical value in the evaluation and treatment of this disease.

Incidentalomas are associated with an increase in liver transplantation in patients with cirrhosis: a single-center retrospective study.

BACKGROUND: Incidentalomas, defined as incidental findings on imaging, are a growing concern. Our aim was to determine the impact and outcomes of extrahepatic incidentalomas on liver transplantation. METHODS: Patients at a large liver transplant center, who had an initial MRI for hepatocellular carcinoma screening between January 2004 and March 2020 were identified. Clinical data were collected retrospectively. Survival analysis, utilizing Kaplan Meier estimates and Cox proportional hazards regression analysis, was utilized to determine factors associated with liver transplantation. RESULTS: 720 patients were included. NASH (24.9%), HCV (22.1%) and alcohol (20.6%) were the most common causes of cirrhosis. 79.7% of patients had an extrahepatic incidentaloma. Older age and having received a liver transplant by the end of the study were associated with an incidentaloma. MELD was not associated with the presence of an incidentaloma. On univariate Cox proportional hazards regression, male sex, history of moderate alcohol use, smoking history, MELD, and incidentalomas were predictors of liver transplantation. On multivariate analysis, only MELD and the presence of an incidentaloma were found to be significant. Discovery of an incidentaloma was associated with a 30% increase in the risk of liver transplantation. Median time to transplantation did not differ based on the presence on an incidentaloma. Patients with cirrhosis from alcohol or HCV had a significantly shorter median time to transplantation than those with NASH. Renal and pancreatic lesions comprised 91% of all incidentalomas. CONCLUSIONS: In this single-center retrospective study, extrahepatic incidentalomas were common in patients with cirrhosis. The finding of an incidentaloma was associated with a higher risk of liver transplantation despite a similar median time to transplantation if no incidentaloma was discovered.

Use of Pharmacogenomics to Guide Proton Pump Inhibitor Therapy in Clinical Practice.

Prescribing the right medication, at the right dose, to the right patient is the goal of every physician. Pharmacogenomic information is an emerging tool that can be used to deliver precision medicine. In this review, we discuss the pharmacogenomics of available PPIs, racial differences of CYP2C19 and how PPI pharmacogenomics affects the treatment of common gastrointestinal diseases. We also provide practical guidance on when to order pharmacogenomic testing, which test to order, and how to modify treatment based on published guidelines.

Safety and Diagnostic Yield of Transthoracic Needle Aspiration of the Lung in Elderly Patients.

BACKGROUND: Pulmonary nodules in elderly patients are commonly encountered in clinical practice. Tissue sampling with image guided transthoracic needle aspiration is often performed but may be complicated by pneumothorax or bleeding. To understand the outcomes of transthoracic needle aspiration in the elderly, we retrospectively reviewed outcomes of patients age 75 or greater in a single tertiary center. METHODS: Four-hundred eleven patients age 75 or greater with a pulmonary nodule identified on computed tomography who underwent needle aspiration of the lung were studied. Diagnostic yield and procedural complications were assessed for each patient and subgroups analysis of those age 85 or greater was performed. RESULTS: Malignancy was confirmed in 70% of subjects and a benign diagnosis identified in 9%. Of the 411 patents, 203 (49.4%) experienced a complication; 150 patients (36.5%) developed a pneumothorax and 79 (19.2%) had bleeding. No patient required transfusion, experienced persistent air leak or massive hemoptysis, air embolism or death. Post procedural hospitalization was required in 36 patients (8.8%) with a median hospital stay of 2 days. No factors were identified to be associated with occurrence of a complication (all p ≥ 0.16) and complications were not increased in those 85 or greater. CONCLUSION: Our results suggest that in an elderly population, image guided needle aspiration of a pulmonary nodule provides diagnostic findings in most patients. Procedural complications following are not uncommon but the severity and long-term impact are limited. The occurrence of complications is similar in those age 75-84 and age 85 and older.

Clinical Characteristics and Outcomes of Patients Hospitalized for COVID-19 Pneumonia Who Developed Bradycardia.

OBJECTIVE: To assess the clinical characteristics and clinical outcomes of bradycardic patients with coronavirus disease 2019 (COVID-19) pneumonia. METHODS: The electronic medical records of 221 consecutive patients hospitalized for COVID-19 pneumonia between June and September 2020 were retrospectively reviewed. Patient characteristics, electrocardiographic data, and clinical and laboratory information were retrospectively collected. Patients not treated with drugs that blunt chronotropic response (nodal) were analyzed separately. RESULTS: Only patients whose heart rate was <60 beats per minute (bpm) (136/221, 61.5%) were included. Serial electrocardiography revealed that most patients (130/137, 97.7%) remained in sinus rhythm. The heart rate was between 50 and 59 bpm in 75% of the patients, while 18.4% were in the 40 to 49 bpm range, and 6.6% were <40 bpm. Medians for development of bradycardia after swab polymerase chain reaction positivity and duration of bradycardia were 41 hours and 5 days, respectively. Bradycardia resolved in 81 patients (59.6%). There were no statistically significant differences in outcomes according to degree of bradycardia (<50 vs 50-59, all P ≥ 0.073). No significant differences were noted for the overall cohort when comparing COVID-19 treatments according to resolution of bradycardia; however, when considering only the patients who were not receiving a nodal agent or antiarrhythmic, treatment with lenzilumab was more common in patients with resolution of bradycardia than patients without resolution of bradycardia (12.2% vs 0.0%, P = 0.030). CONCLUSIONS: Sinus bradycardia occurs frequently in patients with severe COVID-19, but the degree of bradycardia does not correlate with clinical outcomes. Lenzilumab may be associated with the resolution of bradycardia.

Creation of a score to predict risk of high conscious sedation requirements in patients undergoing endoscopy.

BACKGROUND AND AIMS: The administration of intravenous conscious sedation to patients undergoing GI endoscopy carries a risk of cardiopulmonary adverse events. Our study aim was to create a score that stratifies the risk of occurrence of either high-dose conscious sedation requirements or a failed procedure. METHODS: Patients receiving endoscopy via endoscopist-directed conscious sedation were included. The primary outcome was occurrence of sedation failure, which was defined as one of the following: (1) high-dose sedation, (2) the need for benzodiazepine/narcotic reversal agents, (3) nurse-documented poor patient tolerance to the procedure, or (4) aborted procedure. High-dose sedation was defined as >10 mg of midazolam and/or >200 µg of fentanyl or the meperidine equivalent. Patients with sedation failure (n = 488) were matched to controls (n = 976) without a sedation failure by endoscopist and endoscopy date. RESULTS: Significant associations with sedation failure were identified for age, sex, nonclonazepam benzodiazepine use, opioid use, and procedure type (EGD, colonoscopy, or both). Based on these 5 variables, we created the high conscious sedation requirements (HCSR) score, which predicted the risk of sedation failure with an area under the curve of 0.70. Compared with the patients with a risk score of 0, risk of a sedation failure was highest for patients with a score ≥3.5 (odds ratio, 17.31; P = 2 × 10-14). Estimated area under the curve of the HCSR score was 0.68 (95% confidence interval, 0.63-0.72) in a validation series of 250 cases and 250 controls. CONCLUSIONS: The HCSR risk score, based on 5 key patient and procedure characteristics, can function as a useful tool for physicians when discussing sedation options with patients before endoscopy.

Serum Electrolyte Levels and Outcomes in Patients Hospitalized with Hepatic Encephalopathy.

INTRODUCTION AND AIMS: Serum electrolyte derangements are common in patients with decompensated cirrhosis hospitalized for hepatic encephalopathy. There are limited data describing the association between electrolyte levels and outcomes in hepatic encephalopathy. We assessed the association between initial serum electrolyte values and outcomes in patients with hepatic encephalopathy. MATERIAL AND METHODS: A total of 385 consecutive patients hospitalized with encephalopathy were included in the study. Baseline electrolyte levels (sodium, potassium, chloride, bicarbonate, calcium and phosphorus) were measured at the time of admission and assessed for association with outcomes, which included survival, admission to the intensive care unit, requirement for mechanical ventilation, and length of hospital stay. P-values ≤ 0.0083 were considered significant after adjustment for multiple testing. RESULTS: In unadjusted analysis, significant associations were identified regarding both bicarbonate and phosphorus (admission to intensive care unit), and calcium (mechanical ventilation); however these findings weakened and no longer approached statistical significance when adjusting for confounding variables. No other significant associations between serum electrolyte measurements and outcomes were observed. CONCLUSIONS: Our findings suggest that in patients hospitalized with encephalopathy, serum electrolyte measurements are not strong predictors of patient outcome.

Abnormal Liver Enzymes.

Abnormal liver enzymes are frequently encountered in primary care offices and hospitals and may be caused by a wide variety of conditions, from mild and nonspecific to well-defined and life-threatening. Terms such as "abnormal liver chemistries" or "abnormal liver enzymes," also referred to as transaminitis, should be reserved to describe inflammatory processes characterized by elevated alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Although interchangeably used with abnormal liver enzymes, abnormal liver function tests specifically denote a loss of synthetic functions usually evaluated by serum albumin and prothrombin time. We discuss the entities that most commonly cause abnormal liver enzymes, specific patterns of enzyme abnormalities, diagnostic modalities, and the clinical scenarios that warrant referral to a hepatologist.

Patent foramen ovale in liver transplant recipients does not negatively impact short-term outcomes.

AIM: Patent foramen ovale (PFO) is a common atrial septal defect that is largely asymptomatic and often undiagnosed. The impact of a PFO in patients undergoing liver transplantation (LT) is unknown. OBJECTIVE: Assess the impact of PFO and physiologic intrapulmonary shunt (IPS) on the perioperative outcomes of patients who underwent LT. METHODS: We performed a retrospective, intention-to-treat analysis of patients with PFO and controls without PFO who underwent LT at Mayo Clinic in Florida between 2008 and 2013. Patients with physiologic IPS were also analyzed. The cohorts were compared for baseline characteristics, length of stay in the intensive care unit (ICU), postoperative oxygen requirements, 30-d cerebrovascular accidents, and mortality. RESULTS: Of the 935 patients who underwent LT, 10.4% had proven PFO by pre-LT echocardiogram. Control patients (n = 101) were statistically older than PFO and IPS (n = 56) patients, but similar in sex, BMI, Model for End-stage Liver Disease score, American Society of Anesthesiologist score, and left ventricular ejection fraction. PFO and IPS patients had similar length of stay in the ICU, mechanical ventilation times, post-LT oxygen requirements, and 30-d mortality compared to controls. Subgroup analysis showed similar outcomes for large PFO and IPS patients to controls. CONCLUSIONS: The presence of PFO did not have a negative impact on perioperative LT outcomes.

Pantoea agglomerans bacteraemia after uterine artery embolisation: an unusual pathogen.

A woman in her 40s presented to the emergency department (ED) with a 3-week history of nausea, vomiting and diarrhoea. Blood cultures were positive for Serratia and Pantoea agglomerans spp. One month before her ED visit, she underwent targeted uterine artery embolisation with particles by an interventional radiologist. Uterine artery embolisation is considered a safe alternative to surgical removal of fibroids or hysterectomy. The patient was initially treated with targeted antibiotics for a large infected uterine fibroid but ultimately required a hysterectomy for source control. To our knowledge, this is the first documented case of P. agglomerans infecting a uterine fibroid.

Clinical and genetic predictors of cardiac dysfunction assessed by echocardiography in patients with hereditary hemochromatosis.

PURPOSE: Hereditary hemochromatosis (HH) may cause iron deposition in cardiac tissue. We aimed to describe the echocardiographic findings in patients with HH and identify risk factors for cardiac dysfunction. METHODS: In this retrospective study, we included patients with HH who underwent transthoracic echocardiography at our tertiary care center between August 2000 and July 2022. We defined three primary outcomes for cardiac dysfunction: 1) left ventricular ejection fraction (LVEF) < 55%, 2) ratio between early mitral inflow velocity and mitral annular early diastolic velocity (E/e') > 15, and 3) global longitudinal strain (GLS) < 18. Multivariable logistic regression was utilized to identify predictors of cardiac dysfunction. RESULTS: 582 patients (median age 57 years, 61.2% male) were included. The frequency of LVEF < 55%, E/e' > 15 and GLS < 18 was 9.0% (52/580), 9.6% (51/534) and 20.2% (25/124), respectively. In multivariable analysis, non-White race, age, and hypertension were associated with E/e' > 15. No specific HFE genetic mutation was associated with LVEF < 55%. A history of myocardial infarction was strongly associated with both LVEF < 55% and E/e' > 15. In patients with LVEF ≥ 55%, the C282Y/H63D genetic mutation was associated with reduced likelihood of E/e' > 15, p = 0.024. Patients with C282Y/H63D had a higher frequency of myocardial infarction. Smoking and alcohol use were significantly associated with GLS < 18 in unadjusted analysis. CONCLUSION: We found the traditional risk factors of male sex, and history of myocardial infarction or heart failure, were associated with a reduced LVEF, irrespective of the underlying HFE genetic mutation. Patients with a C282Y/H63D genetic mutation had a higher frequency of myocardial infarction, yet this mutation was associated with reduced odds of diastolic dysfunction compared to other genetic mutations in patients with a normal LVEF.

Invasive Nocardiosis Versus Colonization at a Tertiary Care Center: Clinical and Radiological Characteristics.

Objective: To describe the clinical and radiographic findings in a large cohort of patients with positive cultures for Nocardia emphasizing the differences between invasive disease and colonization. Patients and Methods: We conducted a single-center, retrospective cohort study of 133 patients with a positive Nocardia isolate between August 1, 1998, and November 30, 2018, and a computed tomography (CT) of the chest within 30 days before or after the bacteria isolation date. Results: Patients with colonization were older (71 vs 65 years; P=.004), frequently with chronic obstructive pulmonary disease (56.8% vs 16.9%; P<.001) and coronary artery disease (47.7% vs 27%, P=.021), and had Nocardia isolated exclusively from lung specimens (100% vs 83.1%; P=.003). On CT of the chest, they had frequent airway disease (84.1% vs 51.7%; P<.001). Patients with invasive nocardiosis had significantly (P<.05) more diabetes, chronic kidney disease, solid organ transplant, use of corticosteroids, antirejection drugs, and prophylactic sulfa. They had more fever (25.8% vs 2.3%; P<.001), cutaneous lesions (14.6% vs 0%; P=.005), fatigue (18% vs 0%; P=.001), pulmonary nodules (52.8% vs 27.3%; P=.006), and free-flowing pleural fluid (63.6% vs 29.4%; P=.024). The patterns of nodule distribution were different-diffuse for invasive nocardiosis and peribronchiolar for Nocardia colonization. Conclusion: The isolation of Nocardia in sputum from a patient with respiratory symptoms does not equal active infection. Only by combining clinical and chest CT findings, one could better differentiate between invasive nocardiosis and Nocardia colonization.

Comparison of Migraine Characteristics in Patients With and Without Inflammatory Bowel Disease: A Retrospective Cohort Study.

BACKGROUND: Survey studies have found an increased prevalence of migraine in patients with inflammatory bowel disease (IBD). However, the clinical characteristics of migraines in this population are unknown. We conducted a retrospective medical record review study to characterize migraines in the IBD population. METHODS: Six hundred seventy-five migraine patients (280 with IBD, 395 without IBD) who were evaluated at Mayo Clinic Rochester, Mayo Clinic Arizona, or Mayo Clinic Florida between July 2009 and March 2021 were included. Patients with ICD codes for migraine and either Crohn's disease (CD) or ulcerative colitis (UC) were selected. Electronic health care records were reviewed. Patients confirmed to have IBD and migraine were included. Demographic, IBD, and migraine characteristics were collected. Statistical analysis was completed using SAS. RESULTS: Patients with IBD were less often male (8.6% vs 21.3%, P < .001) and had a higher Charlson Comorbidity Index (>2: 24.6% vs 15.7%, P = .003); 54.6% had CD and 39.3% had UC. Patients with IBD had migraine with aura and without aura more frequently ( OR 2.20, P < .001 and OR 2.79, P < .001, respectively) than non-IBD patients. Additionally, those with IBD less commonly had chronic migraine (OR 0.23, P < .001) and less commonly had chronic migraine or treatment for migraine (ORs 0.23-0.55, P ≤ .002). CONCLUSIONS: Migraine with and without aura have increased prevalence in IBD patients. Further study of this topic will be helpful to clarify the prevalence of migraine, establish this population's response to treatment, and better understand the reason(s) for a low rate of treatment.

Lactobacillus rhamnosus sepsis, endocarditis and septic emboli in a patient with ulcerative colitis taking probiotics.

A man in his 60s presented to the emergency room with fever and fatigue after a 2.5-month course of corticosteroids. His medical history was significant for bioprosthetic aortic valve replacement and moderately severe ulcerative colitis treated with balsalazide and daily lactobacillus-containing probiotics. Initial investigations revealed Lactobacillus rhamnosus bacteraemia without complication. Four days after hospital discharge, the patient experienced acute-onset right-sided paraesthesia and lower-limb paresis. On return to the emergency room, MRI of the brain demonstrated innumerable ring-enhancing lesions with haemorrhagic transformation. Transoesophageal echocardiogram revealed a small mobile density on the bioprosthetic aortic valve, raising the suspicion for L. rhamnosus infective endocarditis with secondary septic emboli to the brain. The patient was subsequently treated with intravenous gentamycin and ampicillin, with transition to indefinite oral amoxicillin suppressive therapy. The current case highlights the potential risk of lactobacilli translocation in an immunosuppressed patient with ulcerative colitis taking probiotics.

Assessment of Knowledge Regarding Risks and Benefits of the Use of Non-Vitamin K Antagonist Oral Anticoagulants.

BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOAC) have replaced vitamin K antagonist (VKA) oral anticoagulants as the first-line treatment option for stroke prevention in high-risk patients with atrial fibrillation. With VKA therapy, disease and treatment-related knowledge is associated with improved adherence and outcomes. There is concern that due to the lack of need for ongoing visits for laboratory monitoring in patients on NOACs, there is less opportunity for education, leading to poor disease- and treatment-related knowledge in this patient group. METHODS: One hundred ninety-nine (199) patients presenting to 2 primary care clinics on NOAC therapy were surveyed regarding atrial fibrillation and their knowledge regarding NOACs. Chart review was completed to determine patient characteristics and data obtained was compared with survey results to determine the accuracy of the survey responses. RESULTS: Patients with a lower degree of NOAC knowledge tended to be older (P < .001), have higher Charlson Comorbidity Index scores (P = .001), use apixaban more often (P = .008), and have been on NOACs for a shorter time period (P = .007). CONCLUSIONS: There is an opportunity to improve NOAC-related knowledge in patients with atrial fibrillation. When developing educational interventions, patient characteristics associated with poor knowledge should be considered. Based on our results, these are patients who are older, more medically complex, are on apixaban, and have been on NOAC therapy for a shorter duration.

Hemophagocytic Lymphohistiocytosis for the Internist and Other Primary Care Providers.

Hemophagocytic lymphohistiocytosis (HLH) syndrome is a hyperinflammatory state that leads to life-threatening, disproportionate activation of the immune system and may be confused for and concomitantly exist with sepsis. However, its treatment differs from sepsis, requiring early initiation of immunosuppressive treatment. While HLH syndrome is more commonly diagnosed in children, internists and other primary care providers must be familiar with the diagnosis and treatment of adult patients with HLH in the hospital and outpatient setting. In this article, we review the essentials that an internist and other primary care providers managing adult HLH patients should know.
