Physicians' perception on using a multi-cancer early detection blood test to reduce disparities in cancer screening.

 INTRODUCTION: Cancer causes significant morbidity and mortality in the United States. It is the second most common cause of death in the United States, after heart disease. African Americans are disproportionately affected by malignancy, with overall higher death rates compared to other racial and ethnic groups. Screening tests can identify early stage malignancy allowing for timely intervention. However, African Americans less frequently undergo cancer screening. Advancement in genomic technology has led to the identification of signals for cancer in the blood. This has resulted in the development of multi-cancer early detection (MCED) tests which evaluate for circulating cell-free DNA (cfDNA). This study evaluated physicians' perception of the use of a multi-cancer early detection test (MCED). METHODS: An anonymous, 29 question survey was administered to African American / Black physicians and medical students. Survey participants were identified through the National Medical Association and other professional organizations that included primarily African American physicians. Surveys were excluded from analysis if respondent was non-African American / Black or was not a physician or medical student. The survey collected physician demographics, percentage of African American / Black patients in their practice, patient barriers to screening, potential use of MCED tests and factors influencing decision to recommend testing. Descriptive statistics were generated. Additional analysis was performed using Chi-Square with statistical significance set at p-value <0.05. The survey was pilot tested for reliability and validity. RESULTS: 1196 (681 female, 515 male) physicians and medical students completed the survey. 95.8 % were physicians who were or had been in clinical practice. Fifty-three percent of physicians reported that >40 % of their patients were African American / Black. Barriers to cancer screening included lack of understanding of the importance (33.8 %), lack of or limited insurance coverage (23.5 %), socioeconomic factors unrelated to insurance coverage (16.2 %), fear of cancer (8.8 %), history of racism and bias in the health care system (7.4 %) with 8.8 % reporting 'other' and 1.5 % reporting no perceived barriers. There was a significant difference (p<0.03) in the rate that physicians' perceived racism and bias in the health care system as barrier for cancer screening in African American / Black patients when compared to other patients. Most physicians and medical students indicated that a MCED test would benefit all patients (86.8 %), would encourage further cancer screening tests (83.8 %), and would be beneficial for minority and under-represented patients regardless of socioeconomics or health care access (83.8 %). Seventy-five percent of survey respondents indicated that a MCED test would be beneficial in promoting further cancer screening and early detection in African American / Black patients. Factors that would impact the ordering of an MCED test included scientific evidence and test validity (63.2 %), efficiency, accessibility, ease of ordering and ease of receiving results (11.8 %), insurance coverage (13.2 %) and 'other factors' (11.8 %). DISCUSSION: This is one of the largest surveys to assess physicians' perceptions about MCED testing and is the first study to evaluate the perspectives of African American physicians. It offers insight about physician acceptance and potential incorporation of MCED into clinical practice. It is important that a multifaceted approach is employed to improve cancer outcomes and reduce disparities in survival. MCED tests, a relatively new advancement in genomic technology, have the potential to be an important component in cancer screening strategies.

Delay in prior authorization of biologic therapy: Another possible cause of healthcare disparity in IBD patients.

BACKGROUND: Biologics, a mainstay in inflammatory bowel disease (IBD) treatment, typically require prior authorization from insurance companies. Multiple studies show that African Americans are less likely to be prescribed biologics. The prior authorization process may perpetuate disparities in healthcare. This study evaluated the approval time for biologics in IBD. METHODS: A chart review of IBD patients seen in a university gastroenterology clinic over 5 years was performed. Patient gender, race, IBD subtype, biologic use, and insurance type were recorded. Insurance type was classified as private or public (Medicaid or Medicare). Biologic agents evaluated included infliximab, adalimumab, vedolizumab and ustekinumab. Length of time to approval (TTA) and length of time to first infusion or administration (TFI) were recorded. Analysis was performed using t-testing, Fisher's exact testing, and ANOVA with significance set at p<0.05. The study was IRB approved. RESULTS: 458 charts were analyzed. 66 patients were being treated with a biologic. 42 had private insurance, 16 Medicaid and 8 Medicare. 37 patients had ulcerative colitis, 27 Crohn's disease, and 2 indeterminate colitis. There were 38 men and 28 women. 32 patients were white, 26 African American, 1 Asian, 5 other, and 2 declined identification. Average TTA was 30.5 days (range 1-145) and average TFI was 45.3 days (range 2-166). African Americans were more often on public insurance compared to whites (p=0.0001). Crohn's disease compared to ulcerative colitis patients were more often on public insurance (p=0.017). Significantly more private compared to public insurance patients were on infliximab (p=0.001). Medicaid and Medicare patients had significantly longer mean TTAs than private insurance patients (49.1 and 52.7 vs 19.4 days, p=0.007). African Americans had significantly longer mean TTA compared to whites (45.9 vs 24.8 days, p=0.044). Crohn's disease compared to ulcerative colitis patients had significantly longer mean TTA (39.7 vs 21.8 days, p=0.050). DISCUSSION: This study shows that prior authorization for biologic therapy was longer for African Americans. Patients on public insurance also tend to have a longer TTA, and more African Americans were on public insurance compared to White patients in this study which may explain the difference in biologic access for African Americans.

Boerhaave Syndrome Mimicking Acute Coronary Syndrome.

Boerhaave syndrome, an esophageal perforation due to increased intraesophageal pressure, may mimic other cardiovascular conditions including acute coronary syndrome. In this report, we present a case of a 63-year-old man who presented with chest pain and ischemic electrocardiogram abnormalities, prompting an initial diagnosis of ST elevation myocardial infarction. After coronary stenting, the patient continued to have chest pain, ST segment elevations, and newly elevated cardiac enzymes. A computed tomography scan showed esophageal perforation, requiring endoscopic stenting. This case underscores the diagnostic and therapeutic challenges of Boerhaave syndrome and the importance of considering this condition in adults with chest pain and ischemic electrocardiogram changes.

A Common Infection in a Highly Atypical Patient: Hematochezia From a Cytomegalovirus Colonic Ulcer in a Young and Healthy Immunocompetent Patient.

Gastrointestinal (GI) cytomegalovirus (CMV) infections are far more common in immunocompromised as opposed to immunocompetent patients. Immunocompetent patients who develop GI tract CMV infections are typically older with medical comorbidities. As such, descriptions of GI CMV infections in younger immunocompetent patients are lacking. Here, we present a case of a GI CMV infection in a young and healthy immunocompetent patient. A 41-year-old male with hyperlipidemia and hypothyroidism presented with painless, intermittent hematochezia. He denied changes in bowel habits or appetite, abdominal pain, fevers, chills, fatigue, or weight loss. His history was pertinent for insertive and receptive intercourse with one male partner. Medications were emtricitabine/tenofovir for pre-exposure prophylaxis, levothyroxine, and atorvastatin. A colonoscopy revealed a cecal ulcer surrounded by nodular-appearing mucosa that felt firm and friable when biopsied. The remaining colon and terminal ileum were normal. There was no diverticulosis or hemorrhoids. Pathology was positive for CMV. A subsequent serological evaluation revealed a normal complete blood count and comprehensive metabolic panel. Tests for human immunodeficiency virus, syphilis, viral hepatitis, chlamydia, and gonorrhea were negative. He was treated with valganciclovir 900 mg twice daily for 21 days. A subsequent test for CMV deoxyribonucleic acid polymerase chain was negative. Hematochezia resolved. A repeat colonoscopy revealed normal mucosa in the cecum. GI CMV infections in immunocompetent patients are rare and typically occur in older patients with medical comorbidities. Further, such case reports are needed to inform clinicians about risk factors and the presentation of GI CMV infections in young healthy immunocompetent patients.

Engaging the community on colorectal cancer screening: Additional factors identified by African Americans as potential barriers during focus groups.

OBJECTIVE: African-Americans have the highest rate of colorectal cancer deaths. Adherence to colorectal cancer screening guidelines can improve outcomes. The objective of this study was to evaluate physician trust and barriers to screening utilizing a unique bi-directional learning focus group involving African-American adults and health care learners. METHODS: A focus group of African-American adults from a community church and university health care learners was conducted to identify colon cancer screening barriers. Health care learners were medical students, resident physicians and gastroenterology fellows. Pre-focus group surveys, including the Wake Forest Physician Trust Scale (WFPTS) and a colon cancer screening knowledge survey, were administered. Audio recording of the focus group was transcribed with subsequent thematic analysis. A post-focus group survey evaluated the colorectal cancer screening barriers identified during the focus group. Analysis of pre- and post- focus group surveys was performed using Fisher Exact test with significance set at p<0.05. RESULTS: The focus group consisted of 18 members (7 African-American community members, 11 non-African American health care learners). WFPTS revealed that 83% (86% community members, 82% health care learners; p = 1.0) strongly agree / agree that their physician would advocate for their health. 77% (86% community members, 73% health care learners; p = 1.0) strongly agree / agree that they trusted their physician. 100% recognized that colon cancer screening is recommended. The focus group identified lack of awareness (81%), colonoscopy preparation (81%), trust in physician (60%), lack of insurance coverage (56%), transportation (56%), colonoscopy wait time (50%), insufficient physician discussion (50%) and fear of procedure or cancer (35%) as screening barriers. Post-focus group surveys revealed that community members more frequently identified racial disparity in health care (p = 0.0474), physician respect toward patients (p = 0.0128) and insufficient physician discussion (p = 0.0006) as screening barriers. CONCLUSIONS: Focus group discussion identified multiple barriers for colorectal cancer screening. Notably, differences in the perceptions of African-American community members and non-African-American health care learners about racial disparity in health care, physician respect toward patients and insufficient physician discussion were revealed. The integration of bi-directional focus group learning can be considered as a potential strategy to assist in the development of focused screening interventions.

Icteric Leptospirosis Leading to Multiorgan Failure and Concomitant Pancreatitis.

Leptospirosis is a zoonotic disease caused by the spirochete Leptospira interrogans with a majority of cases occurring in the tropics. Diagnosing leptospirosis is challenging due to the variable and non-specific clinical presentation. While severe leptospirosis may present with renal failure, liver failure, and pulmonary hemorrhage, there are few described cases of renal failure and liver failure accompanied by pancreatitis and dysrhythmias, particularly in temperate climates. We present a case of severe leptospirosis presenting with bilateral calf pain, acute oliguric renal failure, acute liver failure, dysrhythmias, and pancreatitis. Clinicians must consider this diagnosis in temperate climates and consider testing and empirically treating for leptospirosis in patients with similar symptom constellations, vague symptoms, and lab abnormalities of unknown etiology.

Collagenous Gastritis: An Atypical Presentation of a Rare Disease.

Collagenous gastritis is a rare inflammatory condition of unknown etiology defined histologically by subepithelial deposition of collagen bands ≥ 10 µm in the lamina propria. Adults typically present with diarrhea, often attributed to concurrent collagenous sprue or collagenous colitis. Children more commonly present with abdominal pain and anemia, with inflammation typically limited to the stomach. Herein, we present a case of collagenous gastritis in a 38-year-old female with a history of iron deficiency and hypothalamic amenorrhea who presented with a one-year history of microcytic anemia. Celiac disease panel, Helicobacter pylori testing, and anti-parietal cell and intrinsic factor antibodies were negative. Esophagogastroduodenoscopy revealed diffusely erythematous and nodular gastric mucosa in the antrum and pylorus. Biopsy from the gastric body showed complete loss of oxyntic glands and deposition of a thick band of collagen under the surface epithelium infiltrated by a few eosinophils, consistent with collagenous gastritis with severe atrophy. She was treated with omeprazole 40 mg daily for six weeks and iron supplementation. Our patient's symptoms and endoscopic findings are consistent with previously described pediatric, but not adult, cases of collagenous gastritis, yielding insight into the variable clinical presentation of this rare disease.

Better clinical outcomes in hospitalized COVID-19 minority patients with accompanying gastrointestinal symptoms.

BACKGROUND AND AIMS: The novel coronavirus (SARS-CoV-2) is highly contagious pathogen that primarily causes respiratory illnesses. Howerver, multiple gastrointestinal (GI) symptoms have been reported in Coronavirus Disease of 2019 (COVID-19). We conducted a retrospective cohort study of inpatients with COVID-19 at the George Washington University Hospital (GWUH) to assess the prevalence of GI symptoms and their association with clinical outcomes. METHODS: We reviewed the charts of 401 adults admitted to GWUH with positive SARS-CoV-2 tests from February 24 to May 21, 2020, ultimately including 382 inpatients. RESULTS: 87% of our cohort was African American or Latinx. 59% of patients reported at least one GI symptom, with diarrhea being the most common (29%). Patients with GI symptoms were slightly younger (58 +/- 15.8 vs. 65 +/- 16.9, p = 0.0005), have higher body mass index (31.5 +/- Standard Deviation of 8.7 vs. 28 +/- 8.2, p = 0.0001), and more likely to be Latinx (34 vs. 27, p = 0.01). Patients who presented with abdominal pain, nausea, vomiting, or diarrhea had significantly lower rates of death during hospitalization compared to those who did not present those symptoms (Odds Ratio 0.48, 95% Confidence Interval 0.28-0.8, p = 0.004). CONCLUSIONS: Our study suggests that GI symptoms portend a less-severe clinical course of COVID-19 which may reflect a different disease phenotype and lower overall immune response. Additional research should focus on more robust symptom reporting and longer follow-up.

Gastrointestinal and Hepatic Manifestations of COVID-19: Evolving Recognition and Need for Increased Understanding in Vulnerable Populations.

The novel coronavirus, SARS-CoV-2, has caused a global pandemic with high morbidity and mortality. It was first observed to cause a severe acute respiratory syndrome. However, gastrointestinal and hepatic manifestations have been increasingly recognized. Gastrointestinal symptoms include diarrhea, epigastric pain, nausea, and vomiting. Diarrhea is the most common GI manifestation of SARS-CoV-2 and can present without or without respiratory symptoms. Patients with GI symptoms have been associated with longer duration of illness and may be associated with more severe illness. Mechanism of diarrhea is thought to be related to direct viral cytotoxicity occurring when the SARS-CoV-3 enters GI cells via the ACE-2 receptor. Inflammatory response and cytokine release likely contributes to symptoms. SARS-CoV-2 can cause hepatic injury. Studies have shown mild to moderate elevation of liver enzymes. The pattern of liver abnormalities can be hepatocellular, cholestatic or mixed. Patients with severe infection have significantly higher rates of liver injury and worse outcomes. Proposed mechanisms for injury include immune mediated systemic inflammatory response, direct cytotoxicity from viral replication and hypoxia-reperfusion dysfunction. Recent data suggests that GI and hepatic injury may be under-recognized manifestation of SARS-CoV-2 infection. Patients with diarrhea and liver disease may have a worse prognosis. The rapidly evolving literature continues to reveal a growing body of information which enables updated guidance for management. More investigation is needed which focuses on vulnerable patients, including the elderly, those with underlying illness, as well as, racial and ethnic minorities.

African-Americans Are Less Frequently Assessed For Hereditary Colon Cancer.

INTRODUCTION: Colorectal cancer (CRC) is the third most common malignancy in the United States and disproportionately affects African-Americans. Approximately 5-10% of CRC results from hereditary cancer syndromes. A detailed family history is recommended as an initial component of cancer risk assessment to help determine initiation, frequency, screening method and genetic counselling referral. This study evaluated the rate of hereditary CRC risk assessment in African-American and white patients. METHODS: A chart review of all patients referred for CRC screening in a university gastroenterology clinic during a 3 month period was performed. Patient self-described race/ethnicity, gender, age, documentation of multi-generational family medical history (3+ generations) were obtained. Amsterdam II Criteria, Bethesda Criteria and Colorectal Cancer Risk Assessment Tool were used to determine which patients with family histories should receive referrals for genetic counselling. Statistical analysis was performed using Fisher's Exact Test with significance set at p < 0.05. The study was IRB approved. RESULTS: 872 medical records were reviewed, including 452 African-American (276 females, 176 males; mean age 60.2), 263 White (123 females, 140 males; mean age 59.4), 45 Hispanic, and 42 Asian. Multi-generational family history was obtained from 143 (16.4%); 62 African-American (13.7%; 47 females, 15 males), 58 White (22.1%; 37 females, 21 whites), 3 Hispanic (6.7%), and 4 Asian (9.5%). There was a significant difference (p = 0.0050) in the rate of detailed family history in African-Americans and whites. However, African-Americans and Whites similarly qualified for genetic counselling when family history was obtained (p = 0.7915); 58.1% African-Americans (36; 30 females, 6 males) and 50% Whites (29: 19 females, 10 males) qualified for genetic counselling. Overall referral rate to genetic counselling was 16.5% with no significant difference (p = 0.7586) between African-Americans and whites. CONCLUSIONS: CRC risk assessment with detailed family medical history was inconsistently performed in all patients. There was significantly lower rate of obtaining multi-generational family medical histories in African-Americans. Referrals of all patients for genetic counselling and testing were also insufficient. Appropriate identification of individuals at increased risk for hereditary cancer syndromes, particularly African-Americans, is critical to prevention, early detection, and treatment of CRC and improving disparities in care.

Frequency and outcomes of gastrointestinal symptoms in patients with Corona Virus Disease-19.

OBJECTIVES: To characterize the frequency and association of gastrointestinal (GI) symptoms with outcomes in patients with corona virus disease 2019  (COVID-19) admitted to the hospital. METHODS: Records were retrospectively collected from patients admitted to a tertiary care center in Washington, D.C., with confirmed COVID-19 from March 15, 2020  to July 15, 2020. After adjusting for clinical demographics and comorbidities, multivariate logistic regression analysis was performed. RESULTS: The most common  presenting symptoms of COVID-19 in patients that were admitted to the hospital were cough (38.4%), shortness of breath (37.5%), and fever (34.3%), followed by GI symptoms in 25.9% of patients. The most common GI symptom was diarrhea (12.8%) followed by nausea or vomiting (10.5%), decreased appetite (9.3%), and abdominal pain (3.8%). Patients with diarrhea were more likely to die (odds ratio [OR] 2.750; p = 0.006; confidence interval [CI] 1.329-5.688), be admitted to the intensive care unit (ICU) (OR 2.242; p = 0.019; CI 1.139-4.413), and be intubated (OR 3.155; p = 0.002; CI 1.535-6.487). Additional outcomes analyzed were need for vasopressors, presence of shock, and acute kidney injury. Patients with  diarrhea  were 2.738 (p = 0.007; CI 1.325-5.658), 2.467 (p = 0.013; CI 1.209-5.035), and 2.694 (p = 0.007; CI 1.305-5.561) times more likely to experience these outcomes, respectively. CONCLUSIONS: Screening questions should be expanded to include common GI symptoms in patients with COVID-19. Health care providers should note whether their patient is presenting with diarrhea due to the potential implications on disease severity and outcomes.

Expanding telehealth options during the COVID pandemic eliminated racial and age disparities in electronic communication by inflammatory bowel disease patients.

BACKGROUND: Electronic messaging and telemedicine visits increased during the COVID pandemic. African-Americans and older patients have less frequently used electronic messaging with their physicians. This study compares the utilization of virtual health care before and during the COVID pandemic for inflammatory bowel disease (IBD) patients. METHODS: A chart review of all IBD patients seen at an academic medical center from 2014-2020 was conducted to evaluate the use of telehealth options (e-messaging, e-visits) during a pre-COVID and COVID timeframe. Analysis of telehealth use from March - August 2018 and March - August 2020 was performed. Patient age, gender, race, IBD type, electronic messaging and telehealth visits were obtained. A confidential database was created. Statistical analysis was performed using Fisher Exact test with significance set at p < 0.05. The study was IRB approved. RESULTS: 392 patients were in the pre-COVID cohort. There were 204 White, 99 African-American, 11 Asian, and 78 racially un-identified patients. 160 (40.8%) initiated E-communication with their physicians. There was a significant difference in the use of e-messaging based upon age (51.1% < 50 vs 39.7% ≥ 50; p = 0.0396) and race (62.3% White vs 28.2% African-American; p < 0.00001).There were no significant differences in the use of e-messaging based upon patient gender (p = 0.6840) or IBD type (p = 0.6374). There were 295 patients in the COVID cohort. There were 155 White, 83 African American patients, 24 Hispanic patients, 10 Asian patients, and 22 racially un-identified patients. 109 (36.9%) utilized a telehealth option (53 via e-messaging; 56 via telemedicine visit). There was no significant difference in the use of a telehealth option based upon age (36.8% < 50 vs 37.25% ≥ 50 years; p = 1.00), race (42.6% White vs 35.9% African-American; p = 0.2693) or IBD type (p = 0.331). Males used telehealth more than females (46.1% vs 29.7%, respectively; p = 0.0051). DISCUSSION: The COVID pandemic emergency increased e-visits and e-messaging for care delivery. Expanded telemedicine options for IBD patients eliminated previously identified racial and age disparities in virtual medical care. African Americans utilized electronic communication as frequently as Whites during the pandemic. Post-pandemic policy consideration for continued telemedicine options may expand patient-physician engagement and eliminate disparities in health care.

Cyclosporine-Induced Kaposi Sarcoma in a Patient With Ulcerative Colitis.

Kaposi sarcoma (KS) is an angioproliferative neoplasm associated with human herpesvirus-8. Gastrointestinal KS has been well documented in immunosuppressed solid organ transplant patients, with only 26 iatrogenic cases published in patients with inflammatory bowel disease. We report a 24-year-old patient with ulcerative colitis, maintained on cyclosporine for 2 years, who presented with watery, nonbloody diarrhea and weight loss. Colonoscopy revealed human herpesvirus-8-positive hemorrhagic nodules throughout the colon and terminal ileum, with diffuse lymphadenopathy on computed tomography consistent with KS. As gastrointestinal KS may present with symptoms that mimic inflammatory bowel disease, it is critical to maintain suspicion in patients on prolonged immunosuppression to reduce complications.

Risk stratification with video capsule endoscopy leads to fewer hospital admissions in emergency department patients with low-risk to moderate-risk upper gastrointestinal bleed: A multicenter clinical trial.

OBJECTIVE: In US emergency departments (EDs), the physician has limited ability to evaluate for common and serious conditions of the gastrointestinal (GI) mucosa such as a bleeding peptic ulcer. Although many bleeding lesions are self-limited, the majority of these patients require emergency hospitalization for upper endoscopy (EGD). We conducted a clinical trial to determine if ED risk stratification with video capsule endoscopy (VCE) reduces hospitalization rates for low-risk to moderate-risk patients with suspected upper GI bleeding. METHODS: We conducted a randomized controlled trial at 3 urban academic EDs. Inclusion criteria included signs of upper GI bleeding and a Glasgow Blatchford score <6. Patients were randomly assigned to 1 of the following 2 treatment arms: (1) an experimental arm that included VCE risk stratification and brief ED observation versus (2) a standard care arm that included admission for inpatient EGD. The primary outcome was hospital admission. Patients were followed for 7 and 30 days to assess for rebleeding events and revisits to the hospital. RESULTS: The trial was terminated early as a result of low accrual. The trial was also terminated early because of a need to repurpose all staff to respond to the coronavirus disease 2019 pandemic. A total of 24 patients were enrolled in the study. In the experimental group, 2/11 (18.2%) patients were admitted to the hospital, and in the standard of care group, 10/13 (76.9%) patients were admitted to the hospital (P = 0.012). There was no difference in safety on day 7 and day 30 after the index ED visit. CONCLUSIONS: VCE is a potential strategy to decrease admissions for upper GI bleeding, though further study with a larger cohort is required before this approach can be recommended.
