Exploring the impact of therapeutic advances in HIV-related mortality in the United States

Objectives

Mortality from HIV has significantly declined with the introduction of highly active antiretroviral therapy (HAART). This study sought to examine the longitudinal trends in mortality from HIV-related diseases by race, sex, geographical region, and over time as HAART trends changed.

Methods

We queried the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research database and performed serial cross-sectional analyses of national death certificate data for all-cause mortality with comorbid HIV from 1999 to 2020. HIV diseases (International Classification of Diseases, Tenth Revision codes B20-B24, O98.7, R75) were listed as the contributing cause of death. We calculated the age-adjusted mortality ratio (AAMR) per 1,000,000 individuals and determined mortality trends using the Joinpoint Regression Program. Subgroup analyses were performed by sex, race, region, and organ system. The study period was further stratified into three groups when specific drug regimens were more prevalent.

Results

In the 22-year study period, 251,759 all-cause mortalities with comorbid HIV were identified. The leading cause of death was infectious disease (84.0%, N = 211,438). Men recorded a higher AAMR than women (4.66 vs 1.65, P < 0.01). African American individuals had the highest AAMR (13.46) compared to White, American Indian, and Asian individuals (1.70 vs 1.65 vs 0.47). The South region had the highest AAMR (4.32) and urban areas had a higher AAMR compared to rural areas (1.77 vs 0.88).

Conclusions

More than 80% of deaths occurred because of infectious disease over the last 2 decades with a decreasing trend over time when stratified by race, sex, and geographical region. Despite advances in HAART, mortality disparities persist which emphasizes the need for targeted interventions in these populations.

Baker's Yeast Might not always be Good for Everyone - A Case of Percutaneous Gastrostomy Tube Induced Saccharomyces Cerevisiae Peritonitis in an Immunocompromised Patient

Peritonitis, the inflammation of the protective membrane surrounding parts of the abdominal organs, is a common clinical pathology with multifactorial aetiologies. While bacterial infections are well-recognised as a cause of peritonitis, fungal infections remain relatively uncommon especially Saccharomyces cerevisiae, which is commonly used for breadmaking and as a nutritional supplement. This fungus has been reported to induce peritonitis in patients on peritoneal dialysis. However, it has never been reported as secondary to percutaneous endoscopic gastrostomy (PEG) tube insertion in immunocompromised patients. We present a 64-year-old female with a history of human immunodeficiency virus (HIV) who developed S. cerevisiae peritonitis following PEG tube insertion. The case highlights the importance of considering rare organisms when treating immunocompromised patients with peritonitis, especially after gastrointestinal tract penetration or peritoneal membrane disruption.

LEARNING POINTS

Fungal infection can be a cause of peritonitis especially in an immunocompromised patient.Saccharomyces cerevisiae can be a pathological organism and induce serious infections.Early recognition of the cause of peritonitis and controlling the source is critical to prevent complications.

Infective Endocarditis Due to Serratia odorifera: A Case Report and Literature Review

Serratia odorifera from the time of its discovery in the 1970's had been considered a common colonizer of the skin with little pathogenic potential. Cases of human infections caused by S. odorifera are relatively rare. To date, very few cases have been reported describing primarily bloodstream and urinary tract infections. We describe a patient who developed endocarditis due to S. odorifera confirmed with a transesophageal echocardiogram. The patient was treated with six weeks of antibiotics with uneventful recovery. After a thorough review of published literature, we concluded that this is the first case of endocarditis caused by S. odorifera reported in English literature.

Salmonella Group B Ileitis Mimicking Crohn's Disease: A Case Report

Salmonellae, considered among the enteric-fever-causing pathogens, is associated with a range of human infections, including gastroenteritis, bacteremia, and osteomyelitis. Salmonella-induced mesenteric adenitis and terminal ileitis resembling acute appendicitis have been reported in the literature. Here, we present a rare case of a patient presenting with severe acute active ileitis and colitis mimicking Crohn's disease with no prior history of inflammatory bowel disease and found to have Salmonella group B bacteremia.

A Rare Case of Acute Myeloid Leukemia Initially Presenting With Fever of Unknown Origin and Rapidly Progressing Pericardial Effusion

This case report highlights a patient who had persistent fevers for weeks and rapidly progressing pericardial effusion following a positive test for coronavirus disease 2019 (COVID-19) two weeks before presentation to the hospital. The initial thought was that her fever was of infectious etiology, but relevant investigations led to the diagnosis of acute myeloid leukemia (AML). AML, which is characterized by clonal expansion of immature "blast cells" in the peripheral blood and bone marrow resulting in ineffective erythropoiesis and bone marrow failure, is the most prevalent form of leukemia. It is the most aggressive form of leukemia, which has varying prognoses determined by the subtypes. This report explores the association between AML, fever of unknown origin, and pericardial effusion, shedding light on a notable clinical aspect. Fever in AML may be attributed to underlying inflammatory processes, cytokine dysregulation, or bone marrow failure. Recognition of fever as a potential indicator of AML contributes to enhanced clinical vigilance. Pericardial effusions and cardiac tamponade, although rare, can be a presenting feature of AML, and can present side by side with fever of unknown origin as seen in this case report.

Haemophilus Influenzae Epididymo-Orchitis and Bacteraemia in an Immunocompetent Patient

Background

Epididymitis is a common cause of scrotal pain in adults, with coliform bacteria being the most common isolated organisms in patients older than 35.

Case presentation

A 51-year-old healthy patient presented with scrotal pain and swelling, and was found to have epididymo-orchitis and bacteraemia caused by Haemophilus influenzae, which has not previously been reported as a cause of epididymo-orchitis and bacteraemia in immunocompetent patients.

Discussion

Diagnostic studies can help confirm the diagnosis and detect the causative pathogen. In all suspected cases, a urinalysis, urine culture and a urine or urethral swab for nucleic acid amplification tests (NAATs) for Neisseria gonorrhoeae and Chlamydia trachomatis should be performed. Colour Doppler ultrasonography often shows an enlarged thickened epididymis with increased Doppler wave pulsation in epididymitis. H. influenzae are pleomorphic gram-negative rods that commonly colonise the human respiratory tract and are associated with a number of clinical conditions. H. influenzae has been reported as a cause of epididymo-orchitis in prepubertal boys, and in few cases were associated with positive blood cultures. In adults, H. influenzae has been isolated before from urine samples or urethral swabs in patients with epididymitis or epididymo-orchitis.

Conclusion

This case highlights the possibility of H. influenzae causing epididymo-orchitis and bacteraemia in immunocompetent patients. Healthcare providers should consider H. influenzae in the differential diagnosis of epididymitis and epididymo-orchitis in both immunocompetent and immunocompromised patients.

LEARNING POINTS

H. influenzae can cause epididymo-orchitis and bacteraemia in immunocompetent patients. This has not been previously reported.H. influenzae should be considered in the differential diagnosis of epididymitis and epididymo-orchitis in both immunocompromised and immunocompetent patients.Healthcare providers should be aware of the increasing incidence of epididymitis and epididymo-orchitis caused by non-coliform bacteria in patients older than 35 years, especially in immunocompromised patients.

A Rare Case of Polymerase Chain Reaction-Negative Severe Clostridioides difficile Infection

Accurately diagnosing Clostridioides difficile infection (CDI) is crucial for effective patient management. A misdiagnosis poses risks to patients, leads to treatment delays, and contributes to infection transmission in healthcare settings. While using polymerase chain reaction (PCR) to amplify the toxin B gene is a sensitive method for detecting toxigenic C. difficile, there is still a risk of false-negative results. These inaccuracies could have significant consequences for diagnosing and treating CDI, emphasizing the need for careful consideration and other diagnostic approaches. This case report highlights a patient with severe CDI who had negative PCR and toxin and a biopsy showing pseudomembranous colitis on further testing due to persistence and worsening of symptoms. In the diagnosis of C. difficile infection, healthcare providers should consider clinical symptoms, although diarrhea, which is a major sign of CDI, can be due to other causes. Even in the presence of negative PCR results, if a patient displays symptoms consistent with C. difficile-associated disease, healthcare providers may still contemplate treatment.

Kluyvera ascorbata: An Unusual Cause of Septic Shock in a Patient With Urothelial Cancer

Kluyvera ascorbata is a gram-negative bacillus which is a rare cause of clinically significant infections in humans. We report a rare case of K. ascorbata infection causing septic shock in a patient with a history of urothelial cancer. After the antimicrobial susceptibility testing, the patient was successfully treated with ceftriaxone. Recognition of the disease-producing potential of this rare pathogen with prompt initiation of effective antimicrobial coverage is paramount for appropriate management in the adult immunocompromised population. To our knowledge, this is the first case report of septic shock secondary to K. ascorbata urinary tract infection.

A Rare Case of COVID-19 Presenting as Acalculous Cholecystitis

At its onset, coronavirus disease 2019 (COVID-19) commonly presents with generalized myalgia and upper respiratory symptoms. COVID-19 presenting as acalculous cholecystitis has been rarely described in the literature. The following case presents a patient whose first presentation of COVID-19 was acalculous cholecystitis without respiratory symptoms, critical illness, or severe COVID-19 infection.

The Association of Mycobacterium tuberculosis with Kikuchi Syndrome: A Case Report and Literature Review

Kikuchi-Fujimoto disease (KFD) is considered one of the rare benign conditions of unknown etiology presenting with the triad of cervical lymphadenopathy, fever, and weight loss. The inciting cause continues to be elusive. One of the leading thoughts is that it may be a post-infectious immune response of T-cells and histocytes. The most common triggers reported have been viral infections. Treatment mainly revolves around the reduction of the inflammatory response with anti-inflammatory medication and steroids when appropriate. To date, there are very limited reports of Mycobacterium tuberculosis as an inciting agent documented. Here, we present a rare case of Kikuchi-Fujimoto disease following Mycobacterium tuberculosis infection, more than four years after the completion of therapy.

Splenic Abscess: A Rare Complication of Bacterial Pneumonia

Splenic abscess is a rare condition with potentially life-threatening evolution. Hematogenous spread is the most common cause of splenic abscess. Contiguous spread after bacterial pneumonia has rarely been reported in the literature. Early diagnosis can be made by a combination of imaging modalities and clinical features. The successful management of splenic abscess includes timely medical therapy, computed tomography (CT)-guided percutaneous aspiration, and splenectomy. In this report, we discuss a rare case of splenic abscess after hospitalization for bacterial pneumonia. The aim of this case report is to raise awareness about this rare complication so that prompt and appropriate management can be quickly performed to prevent severe outcomes.

Phase 1 study of safety, pharmacokinetics, and antiviral activity of SARS-CoV-2 neutralizing monoclonal antibody ABBV-47D11 in patients with COVID-19

ABBV-47D11 is a neutralizing monoclonal antibody that targets a mutationally conserved hydrophobic pocket distal to the ACE2 binding site of SARS-CoV-2. This first-in-human safety, pharmacokinetics, and antiviral pharmacodynamic assessment in patients with COVID-19 provide an initial evaluation of this antibody that may allow further development. This multicenter, randomized, double-blind, and placebo-controlled single ascending dose study of ABBV-47D11 (180, 600, or 2400 mg) as an intravenous infusion, was in hospitalized and non-hospitalized (confined) adults with mild to moderate COVID-19. Primary outcomes were grade 3 or higher study drug-related adverse events and infusion-related reactions. Secondary outcomes were pharmacokinetic parameters and concentration-time profiles to Day 29, immunogenicity (anti-drug antibodies), and antiviral activity (change in RT-PCR viral load) from baseline to Days 15 and 29. ABBV-47D11 single doses up to 2400 mg were safe and tolerated and no safety signals were identified. The pharmacokinetics of ABBV-47D11 were linear and showed dose-proportional increases in serum concentrations with ascending doses. The exploratory anti-SARS-CoV-2 activity revealed a reduction of viral load at and above the 600 mg dose of ABBV-47D11 regardless of patient demographics and baseline characteristics, however; because of the high inter-individual variability and small sample size a statistical significance was not reached. There is potential for anti-SARS-CoV-2 activity with ABBV-47D11 doses of 600 mg or higher, which could be evaluated in future clinical trials designed and powered to assess viral load reductions and clinical benefit.

1285. Systematic Literature Review of Real-world Experience with the 2-Drug Regimen Dolutegravir and Lamivudine in People with HIV Who Would Not Have Met Inclusion Criteria for the Phase 3 Clinical Program

Background

In phase 3 randomized controlled trials (RCTs), dolutegravir/lamivudine (DTG/3TC) demonstrated durable efficacy in treatment-naive (GEMINI-1/-2) and virologically suppressed switch (TANGO, SALSA) participants. Eligibility criteria for these RCTs included no history of treatment failure or any major nucleoside reverse transcriptase inhibitor or integrase inhibitor–associated mutations, no hepatitis B virus (HBV) or need for hepatitis C virus (HCV) therapy, and viral load (VL) < 500,000 c/mL at screening (GEMINI) or < 50 c/mL for > 6 months (TANGO, SALSA). We analyzed real-world evidence (RWE) for DTG + 3TC use in people with HIV (PWH) with baseline characteristics not consistent with these inclusion criteria.

Methods

We conducted a systematic literature review according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. RWE studies that reported on DTG + 3TC use in PWH were retrieved from Ovid MEDLINE^®, Embase^®, PubMed, Cochrane library, and relevant international conference proceedings from January 2013 to February 2022.

Results

This review includes 122 publications from 103 RWE studies of 44 unique cohorts (N=8034; 42 cohorts outside the United States; Tables 1-2, Figure). In the 1 study that described outcomes in PWH with previous virologic failure (VF; N=194), probability of VF at 1 year was low (0.4% or 1.2%, depending on VF criteria). In cohorts with > 10 PWH with baseline resistance that reported outcomes (mostly M184V/I; 4 cohorts, N=211), VF was low (ranging from 0%-5.4% at ∼1 year), and the difference in VF between those with or without M184V/I was not significant in 3 of 4 cohorts. A treatment-emergent resistance mutation (M41L, not selected by DTG or 3TC) was observed in 1 PWH with evidence of baseline resistance. None of the 35 PWH with HBV experienced VF, and 89% (16/18) of treatment-naive PWH with baseline VL > 500,000 c/mL achieved virologic suppression at Week 24. There were no studies describing effectiveness outcomes in PWH with HCV who were receiving DTG/3TC.

Conclusion

DTG + 3TC has been used in PWH with various baseline characteristics, including RCT exclusion criteria. Outcomes from published RWE in these subgroups further support the clinical data demonstrating the high effectiveness and barrier to resistance of DTG + 3TC.

When Influenza, Bacterial Pneumonia, and COVID-19 Co-exist

In the United States, influenza virus and bacterial pneumonia are known to be the leading causes of hospitalization in the winter season. Although healthcare workers are knowledgeable about the management of these co-infections, with the coronavirus disease 2019 (COVID-19) global pandemic that occurred in 2019, a significant change has occurred. The symptoms and clinical manifestations of COVID-19 are similar to that of influenza virus and bacterial pneumonia which can present a unique challenge for healthcare workers. Many reports are available for influenza virus and bacterial pneumonia but none about influenza, bacterial pneumonia, and COVID-19 co-infection. Here, we present the case of a patient who was admitted with COVID-19, influenza, and bacterial pneumonia co-infection, along with his clinical characteristics, laboratory findings, treatment plan, and outcomes.

Functionality of Monoclonal Antibody Therapy in SARS-CoV-2

The coronavirus disease 2019 (COVID-19) pandemic emerged as a world crisis in 2019 and started a global search for optimal therapeutic regimen including vaccines, antiviral agents, and recently monoclonal antibody therapy. Clinical trials are currently underway for the efficacy of several neutralizing monoclonal antibodies against COVID-19. The evolution of new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants with immune evasion capacity has created a challenge for the healthcare workers with urgent need for prospective studies to determine functionality of monoclonal antibody therapy and their role in the reduction of hospitalization for disease severity. Herein, we report three cases of COVID-19 during the beginning of the spread of Omicron variants that were hospitalized after treatment with monoclonal antibody therapy in the emergency department. All the patients showed progression of the disease on imaging and were treated with dexamethasone, remdesivir and anticoagulation based on the symptoms and contraindications. Two of the patients recovered and were discharged with out-patient follow-up; however, one patient expired in the hospital. Monoclonal antibody therapy is a promising treatment to limit the progression of COVID-19 and reduce the hospital strain specifically in small community hospitals. Limited information is available about their efficacy in the new viral variants. These cases emphasize the need of future prospective study and randomized controlled trials to illustrate the utilization of monoclonal antibodies as a therapeutic modality in patients infected with the variants of SARS-CoV-2.

An Unusual Case of Secondary Hemophagocytic Lymphohistiocytosis in a Patient Diagnosed With Triple Infection: COVID-19, HIV, and Histoplasmosis

In this study, we present a unique instance of a patient who developed hemophagocytic lymphohistiocytosis secondary to a triple infection with coronavirus disease 2019 (COVID-19), HIV, and histoplasmosis. We emphasize the proinflammatory dysregulations driving the severity of COVID-19 infection in this setting and highlight the importance of early diagnosis and targeted therapy of underlying conditions as a method to increase the chance of survival.

Late Evolution of Deep Neck Space Abscess: Was Intubation the Cause?

Introduction

Deep neck abscess in adults may occur as a result of local trauma, foreign body inoculation or immunosuppression.

Method

We describe a case of deep neck abscess that developed after recent hospitalization and intubation for chronic obstructive pulmonary disease (COPD) exacerbation.

Discussion

The incidence of deep neck abscesses has dramatically reduced due to the use of antibiotics. However, if present, they need prompt surgical drainage due to their proximity to the nearby vasculature of the neck.

Conclusion

This case highlights the need for physician awareness of the clinical presentation of the unique complications of deep neck abscess developing after hospitalization.

Persistent Methicillin-Resistant Staphylococcus Aureus Bacteremia Secondary to Infected Seroma: A Rare Case Report

A seroma is defined as a serous fluid collection that develops as a response to injury and surgeries, particularly mastectomy and reconstructive and abdominal surgeries. The majority of the seromas are self-limiting and arise in the acute postoperative period; however, diagnosis of seroma several years after surgery has also been reported in the literature. Persistent bacteremia with infected seroma as a source is a rare entity. We present the first case to be reported of persistent bacteremia secondary to infected seroma with septic emboli to lungs and prostate without any evidence of endocarditis on multiple echocardiograms. This case highlights the importance of meticulous physical examination and source control in the management of bacteremia.

Clinical outcomes after IL-6 blockade in patients with COVID-19 and HIV: a case series

BACKGROUND

In hospitalized people with HIV (PWH) there is an increased risk of mortality from COVID-19 among hospitalized PWH as compared to HIV-negative individuals. Evidence suggests that tocilizumab-a humanized monoclonal interleukin (IL)-6 receptor inhibitor (IL-6ri) antibody-has a modest mortality benefit when combined with corticosteroids in select hospitalized COVID-19 patients who are severely ill. Data on clinical outcomes after tocilizumab use in PWH with severe COVID-19 are lacking.

CASE PRESENTATION

We present a multinational case series of 18 PWH with COVID-19 who were treated with IL-6ri's during the period from April to June 2020. Four patients received tocilizumab, six sarilumab, and eight received an undocumented IL-6ri. Of the 18 patients in the series, 4 (22%) had CD4 counts < 200 cells/mm³; 14 (82%) had a suppressed HIV viral load. Eight patients (44%), all admitted to ICU, were treated for secondary infection; 5 had a confirmed organism. Of the four patients with CD4 counts < 200 cells/mm³, three were treated for secondary infection, with 2 confirmed organisms. Overall outcomes were poor-12 patients (67%) were admitted to the ICU, 11 (61%) required mechanical ventilation, and 7 (39%) died.

CONCLUSIONS

In this case series of hospitalized PWH with COVID-19 and given IL-6ri prior to the common use of corticosteroids, there are reports of secondary or co-infection in severely ill patients. Comprehensive studies in PWH, particularly with CD4 counts < 200 cells, are warranted to assess infectious and other outcomes after IL-6ri use, particularly in the context of co-administered corticosteroids.

Severe Gastroparesis Flare: Is COVID-19 the Inciting Factor?

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has emerged as a public health hazard. It is commonly associated with respiratory symptoms including fever, cough and sore throat. Viral infections have historically been implicated in the exacerbations of gastrointestinal (GI) disorders. Coronavirus disease 2019 (COVID-19) has been associated with GI manifestations including diarrhea and vomiting. However, exacerbation of underlying functional GI disorders has been rarely reported with SARS-CoV-2 infection. Herein we report a case of a 31-year-old female with acute gastroparesis flare secondary to COVID-19 which was refractory to pharmacological therapy.

Dilemma of Anticoagulation Therapy in Mild or Asymptomatic COVID-19 Cases

Severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV-2) infection can be a life-threatening disease, which has emerged as a public health hazard. Thrombotic events have been reported in hospitalized patients with severe disease however scarce data is available regarding the screening of thromboembolic disease and pulmonary embolism in those with mild or asymptomatic infection. Herein, we describe the development of pulmonary embolism in two asymptomatic patients with COVID-19 and suggest the need for close monitoring and anticoagulation to prevent this life-threatening complication.

455. Diagnostic Value of Hematological Parameters in Different Stages of the Disease in Covid-19 Patients

Background

COVID-19 infection is associated in some individuals with a rapid onset of systemic proinflammatory state leading to cytokine storm followed by multisystem organ failure. We are interested in studying the prognostic value of complete blood count parameters in different stages of the diseases based on the serology.

Methods

This is a retrospective cohort study of patients with confirmed COVID-19 admitted to our hospital between 10/1/2020 to 2/28/2021. Study individuals had complete CBC profile and COVID-19 serology with well-defined clinical outcome (discharged alive or expired). They were divided in 3 groups based on serology results: group 1 (early disease) had no antibodies, group 2 (immune phase) had + IgM, and group 3 (late phase) had only + IgG. Demographic, clinical and laboratory data were reviewed. Simple t-test was used for continuous variables and chi-square test was used for categorical variables. Anova test was used to compare the difference across multiple groups. GraphPad PRISM was used for all analysis.

Results

A total of 202 confirmed covid 19 cases were included in the study. There was no difference between the 3 groups in terms of age, gender, and body mass index (BMI). We did observe an increase in incidence in Latinx (group 1, 34%; group 2, 51%; group 3, 38%). Hypertension and diabetes were major co-morbidities in these patients. Absolute neutrophil count (ANC) and platelet count (PC) showed significant changes across the 3 groups: mean ANC for group 1, 4.868 (SD 3.117); group 2, mean 6.951 (SD 3.843); and group 3 mean 5.59 (SD 3.236). PC in group 1 mean 193.2 (SD 90.25); group 2 mean 271.1 (SD 143.4); and group 3 mean 228.6 (SD 75.33) p-value 0.0008. The difference can be seen in the derived monocyte platelet rationMPR, neutrophil lymphocyte ratio NLR, platelet lymphocyte ratio PLR and aggregate index of systemic inflammation AISI values and they tend to be higher in group 2 (MPR p-value 0.0067, NLR p-value 0.0123, PLR p-value 0.0294, AISI p-value of 0.0190).

Baseline characteristic

Conclusion

The study demonstrates that MPR, NLR, PLR and AISI have a potential role in categorizing the disease stage based on only CBC profiling.Properly designed prospective studies with a larger sample size should be performed to confirm the disease stratification ability of derived CBC indices like MPR, NLR, PLR and AISI.

Varicella-Zoster Virus Reactivation in AIDS Patient After Pfizer-BioNTech COVID-19 Vaccine

Since early 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected millions of individuals and changed the face of medicine. As the fight against COVID continues, there is still unclear long term effects; although as time passes, more and more is being updated, in regards to the risks of exposure, length of recovery, outcomes of those infected, effectiveness of vaccines, and both expected and unique side effects of both the virus and vaccines, all in an array of individuals. This paper will review a unique topic of the SARS-CoV-2 virus and the abnormal immune response in a young patient. This case is unique due to the fact that there have been an abundance of side effects reported that are associated with the virus that affects every organ system, yet very few have affected the neurological and integumentary (skin) system. This case emphasizes the reactivation of a Herpes/Varicella-Zoster virus (VZV) in a young male shortly after he received the Pfizer-BioNTech COVID-19 vaccine. The other interesting aspect about this case is the patient’s immunocompromised state, as he was diagnosed with HIV several years before this viral reactivation occurred. The interesting aspect about this was trying to understand whether the VZV was truly reactivated because of an overly stressful immune reaction in response to the Pfizer-BioNTech COVID-19 vaccine or was it mainly due to the patient’s already weak immune system, or even a combination of both? The in-depth review will evaluate whether there should be more done in regards to bringing more awareness about potential side effects and preparing for a VZV reactivation and/or other dermatological complications after being vaccinated. This presentation could also simply be a very unique, isolated case, and that each individual should have no hesitations regarding the Pfizer-BioNTech COVID-19 vaccine. 

Fournier's gangrene mimicking an acute epididymitis

Fournier's gangrene is a urologic emergency secondary to a necrotizing soft tissue infection. Fournier's gangrene is characterized by severe pain and features of Fournier's gangrene may include edema, blisters and bullae, crepitus, subcutaneous gas, and systemic symptoms. Risk factors include male gender, alcohol abuse, immunocompromised state, uncontrolled diabetes mellitus, obesity, and malignancy. The diagnosis is made clinically but is often supported by radiography, ultrasound, computed tomography, and magnetic resonance imaging. Treatment consists of emergent hospitalization and surgery to debride the necrotic tissues. Morbidity and mortality for Fournier's gangrene are very high if left untreated. Early surgical intervention is key to the successful treatment of Fournier's gangrene. This case report presents a case of Fournier's gangrene mimicking acute epididymitis and highlights the importance of a thorough physical examination with high clinical suspicion for Fournier's gangrene.

Cardiac Tamponade Associated with Human Immunodeficiency Virus-Associated Immune Complex Kidney Disease

Cardiac tamponade is a life-threatening emergency, characterized by rapid accumulation of pericardial fluid. There are multiple risk factors for cardiac tamponade, nephrotic syndrome is an uncommon one, especially in adults. Herein, we are reporting a 35-year-old African American woman with membranoproliferative glomerulonephritis secondary to human immunodeficiency virus-associated immune complex kidney disease (HIVICK), who presented with cardiac tamponade. The patient had pericardiocentesis and was discharged, with outpatient follow-up with cardiology, nephrology, and infectious disease. To the best of our knowledge, this is the first report of HIVICK nephrotic syndrome associated with cardiac tamponade.

A Case Series of SARS-CoV-2 and Influenza Co-infection

The novel coronavirus 2019, a disease associated with SARS-CoV-2 infections has resulted in significant morbidity and mortality across the globe. In the United States, influenza has been one of the leading causes of hospitalization during the winter season. To date, the co-infection of SARS-CoV-2 and influenza virus has created a unique challenge for healthcare workers, especially during the cold season. Both viruses have similar clinical presentation and transmission characteristics. Many reports are available for either SARS-CoV-2 and influenza individual infections, but limited data are available for the co-infection. Herein, we present a case series of five cases of SARS-CoV-2 and influenza co-infection as well as their clinical characteristics, laboratory findings, management, and outcome.

A successful initiation of treatment of Hodgkin's lymphoma with adriamycin-bleomycin-vinblastine-dacarbazine dose reduction in a patient with fulminant hepatic failure and co-infection with human immunodeficiency virus and hepatitis B

INTRODUCTION

Hodgkin lymphoma is a highly curable lymphoproliferative malignancy with an overall relative survival rate of 87.4%. It is characterized by multinucleated Reed-Sternberg cells which are mostly derived from B cells in the germinal center.

CASE REPORT

We present a case of a 40-year-old gentleman with acquired immunodeficiency syndrome who presented with Stage 4b Hodgkin lymphoma complicated with fulminant hepatic failure and direct hyperbilirubinemia. The initial presentation of Hodgkin lymphoma as cholestatic jaundice is extremely rare.

MANAGEMENT AND OUTCOME

Though the survival rate with chemotherapy is high, the fulminant hepatic failure made the situation challenging with the use of chemotherapeutic regimens that require hepatic excretion. He received dose reduced adriamycin-bleomycin-vinblastine-dacarbazine regimen [doxorubicin 12.5 mg (6.75 mg/m²), bleomycin 18 units (10 units/m²), vinblastine 3 mg (1.5 mg/m²), dacarbazine 380 mg (190 mg/m²)] as well as bictegravir/emtricitabine/tenofovir alafenamide since admission for treatment of human immunodeficiency virus and hepatitis B. He started responding with the first cycle of dose reduced adriamycin-bleomycin-vinblastine-dacarbazine regimen with bilirubin levels trended down and normalized as well as his clinical condition improved. He received the full dose of adriamycin-bleomycin-vinblastine-dacarbazine on day 15.

DISCUSSION

Our case report emphasizes that the early usage of dose reduced adriamycin-bleomycin-vinblastine-dacarbazine regimen can restore hepatic function and can achieve improvement in hepatic function allowing the delivery of full-dose chemotherapy.

The Roles of Fibrosis Index Based on Four Factors and Aspartate Transaminase-to-Platelet Ratio Index Scoring Systems as an Alternative to Transient Elastography Liver Stiffness in Liver Fibrosis Staging in Human Immunodeficiency Virus and Hepatitis C Virus Co-Infected Patients

Background

Liver biopsy used to be the gold standard to assess liver fibrosis in patients infected with hepatitis C virus (HCV). Nonetheless, due to its invasive nature, techniques such as transient elastography liver stiffness (TE-LS), fibrosis index based on four factors (FIB-4) and aspartate transaminase-to-platelet ratio index (APRI) scores are currently being used. FIB-4 and APRI scores have the advantage of low cost and are readily available, compared with TE-LS. Herein, we evaluated the diagnostic performance of these scoring systems as compared to TE-LS in assessing liver fibrosis in patients with human immunodeficiency virus (HIV) and HCV co-infection.

Methods

The medical records of patients with HIV and HCV co-infection who had TE-LS done at our facility between August 1, 2013 and January 1, 2020 were extracted and analyzed. Exclusion criteria include: 1) patients co-infected with hepatitis B virus; 2) invalid TE-LS assessment; 3) have ≥ 10th upper limit of normal (ULN) alanine aminotransferase (ALT) levels; and 4) excessive alcohol use. Patient demographics, medical history, biochemical and clinical data were retrieved. For each patient, we calculated the FIB-4 and APRI score. Descriptive analysis was performed and correlation of FIB-4 and APRI with TE-LS was assessed with GraphPad Prism statistical software.

Results

Five hundred forty-seven patients underwent TE-LS during the study period. After excluding those without complete laboratory parameters, the total study population was 344. Their age was 56 ± 10.4 years and 234 (68%) were male. The average aspartate aminotransferase (AST) and ALT were 27.95 and 30.73. The average platelet count was 224 and the average TE-LS was 7.29. Fourteen patients (4.1%) had TE-LS values between 9 and 11.9 kPa and were classified as F3, while 29 (8.5%) had TE-LS ≥ 12 kPa and were classified as F4. With the correlation analysis, both APRI (correlation coefficient, r = 0.1097, 95% confidence interval (CI) 0.0403 - 0.2130; P = 0.042) and FIB-4 (r = 0.0424, 95% CI -0.0634 - 0.1474; P = 0.4335) were not correlated with TE-LS stages of fibrosis.

Conclusion

In our cohort, we failed to demonstrate that APRI and FIB-4 are reliable alternatives for screening liver fibrosis in patients with HIV and HCV co-infection. Nonetheless, APRI score still has a potential role as a screening tool instead of TE-LS measurement, which is costly and not readily available. It will be important to corroborate these findings in another large cohort, since this may have an important impact on patient management.

Ipsilateral Zoster Ophthalmicus Post COVID-19 Vaccine in Healthy Young Adults

Herpes zoster ophthalmicus (HZO), which is an ophthalmological emergency, accounts for 10%-20% of all Herpes zoster (HZ) cases. HZ infection in COVID-19 vaccinated individuals who are immunocompetent can be attributed to vaccine-induced immunomodulation allowing the varicella-zoster virus (VZV) to escape from the dorsal root ganglia. Another theory is similar to immune reconstitution syndrome (IRS). HZ infection in a young immunocompetent individual is a rare entity. As per our literature review, only four cases have been reported thus far. We are reporting two cases of two young individuals with no known risk factors who developed ipsilateral HZO after receiving the COVID-19 vaccination. The increasing incidence of HZ cases post COVID-19 vaccine indicates that this is not a mere coincidence. Awareness must be created among physicians, as well as the general population, for early recognition and early antiviral usage, which can halt the progression of the disease and thus prevent debilitating complications.

Cerebral Air Embolism After Gastrointestinal Procedure: A Case Report and Literature Review

Esophagogastroduodenoscopy (EGD) is one of the forefronts of minimally invasive modalities with excellent safety records and tremendous capability but despite its accolades and functions, there are still very rare complications including air embolism. It is a life-threatening condition that could lead to a significant increase in morbidity and mortality. However, there are limited data for incidence of air embolism in association with gastrointestinal endoscopy. Diagnosis of air embolism after or during gastrointestinal endoscopy might be a difficult task due to overlapping presentations with anesthesia effects on the cardiopulmonary and the neurological systems, as a result, there should be increased awareness allowing clinicians to quickly rule out air embolism in patient with altered mental status or cardiopulmonary changes after or during gastrointestinal endoscopy. Herein, we report a unique case of cerebral air embolism after EGD in a 79-year-old female patient. In addition, we also performed a systematic review of cases based on PRISMA guideline, with the aim to investigate the demographics and clinical outcomes associated with this complication. This systematic review of cases hopes to increase the awareness about this rare entity.

Left ventricular thrombus complicated by acute limb ischemia in a patient with HIV

Left ventricular thrombus typically occurs in patients with impaired left ventricular function such as aneurysm, dilated cardiomyopathy, or post-myocardial infarction. Untreated HIV infection is known to increase the risk of venous thromboembolism and cardiovascular disease. However, the pathophysiology remains uncertain; some studies have proposed chronic inflammation as the underlying etiology. Nonetheless, left ventricular thrombus is extremely rare among persons living with HIV with no known underlying cardiac disease. Herein, we report an unusual case of a 55-year-old homeless and heterosexual male with past medical history of HIV, who has mildly reduced left ventricular function and a nonmobile, medium size left ventricular thrombus. Patient was initially treated with therapeutic dose of enoxaparin, and subsequently developed acute embolic occlusion of right femoral artery that lead to an above knee amputation. To our knowledge, left ventricular thromboembolism complicated with acute embolic ischemia in persons living with HIV is extremely rare. The presenting case will definitely add to the current body of knowledge and will raise awareness among physicians, in recognizing the rare association between HIV and arterial thromboembolism.

Roles and Interplay of SARS-CoV-2 Serology With Clinical Stages of Disease in COVID-19

Background

Currently, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serology is recommended only for seroprevalence. We think it could be useful in differentiating coronavirus disease 2019 (COVID-19) stages, which could in terms of helping improve our therapeutic interventions.

Methods

The medical records of adult patients admitted to the hospital with probable COVID-19 were extracted and analyzed. We excluded patients with no serology and no clear outcome at the end of data collection. Patient demographics, medical history, and biochemical and clinical data were retrieved.

Results

A total of 202 patients were included; 57% were males, the majority were Hispanic (45%), followed by African Americans (22%). Hypertension is the most common comorbidity, followed by diabetes mellitus and chronic kidney disease. We classified them into three groups based on their serology: subacute stage (47 patients) with both immunoglobulin M (IgM) and IgG negative; acute stage (116 patients) with IgM positive and late-stage (39 patients) with IgM negative and IgG positive. We found that elevated lactate dehydrogenase (LDH) and ferritin were present in the IgM+ and IgM-/IgG+ subgroups (p-value of 0.0061 and p-value 0.0013, respectively) while C-reactive protein (CRP) and D-dimer were more elevated in the IgM-/IgG- and IgM+ subgroups (P <0.0001 and p-value of 0.0452, respectively). The IgM+ group had the worst prognosis, with high mortality despite receiving remdesivir and dexamethasone.

Conclusion

Our findings suggest that the use of serology in patients hospitalized with COVID-19 could predict prognosis; this will need to be validated in a larger prospective study.

A rare presentation of transient hypothermia in HIV infection: A case report and systematic review of cases

Hypothermia defined as a core body temperature less than 35°C causes hundreds of deaths annually in the United States. It can occur in a variety of clinical settings, including environmental exposure, shock, infection, metabolic disorders, alcohol, or drug toxicity, and malnutrition. This condition can affect many different organ systems and may lead to serious complications including cardiac arrhythmia. Hypothermia is extremely rare in people living with HIV but can be seen in severely malnourished patients or those who are not receiving antiretroviral therapy (ART). It is a life-threatening situation that should be treated aggressively. To the best of our knowledge, there are only a few cases that have been reported for people living with HIV presenting with hypothermia and sinus bradycardia. Herein, we are reporting a very rare case of people living with AIDS who presented with hypothermia complicated by sinus bradycardia. In addition, we also performed a systematic review of cases based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline, to investigate the clinical characteristics and outcomes associated with this rare complication. This systematic review of cases hopefully can increase the awareness of this rare entity and help improve its outcome.

Tocilizumab and Thromboembolism in COVID-19: A Retrospective Hospital-Based Cohort Analysis

Background

Tocilizumab, an interleukin-6 (IL-6) receptor antagonist, has been used in patients with coronavirus disease 2019 (COVID-19) as an anti-cytokine agent. IL-6 also plays a complex role in hemostasis and thrombosis. We observed a transient elevation of D-dimer in our patients who received tocilizumab, which triggered this study.

Methods

A retrospective hospital-based cohort analysis of patients with confirmed COVID-19 who received tocilizumab during the study period of March 15, 2020, to May 20, 2020, was conducted. We retrieved demographic, clinical, and laboratory data, and patients who were receiving therapeutic anticoagulation therapy prior to tocilizumab administration were excluded. Descriptive analysis was performed, and the cause of death and trends of D-dimer and inflammatory markers were studied.

Results

Out of the 436 confirmed COVID-19 patients admitted during the study period, 24 met the inclusion criteria. Their median age was 47.5 years. They were 18 males and 6 females; 15 patients survived and nine expired. Of the group that survived, 12 received therapeutic anticoagulation. Of the seven patients who did not receive therapeutic anticoagulation, four expired (one from sepsis and three probably from thromboembolic complications) compared to five deaths in the 17 patients who received therapeutic anticoagulation (four from sepsis and one possibly from thromboembolic complications).

Conclusions

The interplay between IL-6, IL-6 receptor antagonist, and venous thromboembolism is complex. We observed a transient elevation of D-dimer in COVID-19 patients who received tocilizumab, and a trend toward increased death secondary to thromboembolism. This observation is novel and highlights the potential thrombophilic side effects of tocilizumab.

Coronavirus Disease 2019 Infection as a Risk Factor for Infective Endocarditis

Infective endocarditis (IE) is associated with relatively high morbidity and mortality and several risk factors have been identified in the past. Several predisposing factors for IE have been recognized in the literature, depending on the type of bacteria. Coronavirus disease 2019 (COVID-19) infection causes coagulopathy-associated complications and damage to many organ systems due to the inflammatory response induced by this viral infection. COVID-19 emerged only about a year ago and there are many unknown post-COVID-19 complications at this time. Here, we present the case of Streptococcus mitis IE in a patient with no prior predisposing factors other than diagnosis with COVID-19 a month ago.

Persistent Hypercoagulable State in COVID-19: A Case Series of COVID-19 Associated Pulmonary Embolism

Coronavirus disease 2019 (COVID-19) has swept through the world with millions of cases and hundreds of thousands of deaths. COVID-19-associated coagulopathy has been recognized as the major cause of morbidity and mortality. To the best of our knowledge, a majority of the cases of coagulopathy have been reported in patients with moderate-to-severe COVID-19 and limited to observations during the recovery/postcytokine storm state. Herein, we report a case series of two patients with COVID-19 who developed pulmonary embolism in the late phase of the disease. This raised the hypothesis that the risk of hypercoagulability in patients with COVID-19 can persist until the recovery phase, which would warrant a follow-up with D-dimer and fibrinogen trending, as well as postdischarge thromboprophylaxis for at least 2 weeks during the recovery phase.

A Case of Co-occurrence of COVID-19 and Group A Streptococcal Pharyngitis

Coronavirus disease 2019 (COVID-19) has swept the world with over hundred million of cases and millions of deaths. Upper respiratory tract symptoms including acute pharyngitis are the common symptoms of COVID-19, with a reported incidence of about 5%-17.4%. Group A Streptococcus (GAS) pharyngitis is a common cause of bacterial pharyngitis, with highest incidence between age 5 and 15, and it can still occur in adults with peak incidence at age 40. Herein, we report a case of co-occurrence of GAS and COVID-19 in a middle-aged man who presented with fever, sore throat, cough, and runny nose. To the best of our knowledge, we are the first to report this unique co-occurrence. Our case report aimed to raise the awareness among physician particularly in ambulatory and emergency department of not to have a singular focus on COVID-19 and forget to screen patient with acute pharyngitis for GAS.

Marantic Endocarditis Associated with COVID-19: A Rare Case Report of a Potentially Deadly Disease

Coronavirus disease 2019 (COVID-19) has overwhelmed healthcare globally with millions of cases and over 2 million deaths worldwide. The hypercoagulable state associated with COVID-19 is a well-recognized complication that carries a poor prognosis. Marantic endocarditis, or non-bacterial thrombotic endocarditis (NBTE), is caused by a sterile vegetation on the cardiac valves resulting from the deposition of fibrin and platelet aggregates. It is highly associated with the hypercoagulable and acquired inflammatory states. Herein, we report a unique and rare case of COVID-19 presenting with NBTE.

LEARNING POINTS

COVID-19 has caused a major global pandemic, with high morbidity and mortality.One of the complications of COVID-19 infection is a hypercoagulable state.To the best of our knowledge, we present only the second case of marantic endocarditis in a patient with COVID-19, in the hope of raising awareness among physicians of this potential rare association.

Concurrent Serotonin Syndrome and Prolong QT Interval Induced by Paroxetine Overdose With Isotretinoin

The use of serotonergic drugs has increased in the last decade especially selective serotonin reuptake inhibitors (SSRIs) with increased indications. Serotonin syndrome (SS) and QT prolongation are serious adverse reactions of SSRI use, they usually occur with concomitant use of two or more serotonergic medication. Herein, we are presenting an interesting unique case of SS and prolongation of QT interval after a suicidal attempt in a patient on isotretinoin with paroxetine overdosing. The prolongation of QT interval observed in this case could be related to isotretinoin synergistic effect. The risk of suicide and side effects of SSRI with isotretinoin, especially in patient with psychiatric illness would be a huge concern. This case hopes to raise the awareness of the risks when prescribing SSRI and isotretinoin in this group of patients.

A Case of Bordetella bronchiseptica Bacteremia in a Patient With Decompensated Liver Cirrhosis

Bordetella bronchiseptica is a rare cause of respiratory tract infection in humans, most commonly found in immunocompromised individuals exposed to infected animals. It colonizes the respiratory tract and can lead to infection in dogs, cats, rabbits, and others. In immunocompromised patients, it has been reported to result in life-threatening infections but rarely affects immunocompetent individuals. Here, we are the first to report a case B. bronchiseptica bacteremia in a patient with decompensated liver cirrhosis without known animal exposure.

A Rare Case Report of Persistent Hiccups as an Atypical Presentation of COVID-19

Sudden, involuntary spasm of the diaphragm associated with closure of the glottis will lead to a hiccup sound. Brief episodes of hiccups are often self-limiting and may be physiologically encountered in everyday life. However, prolonged attacks of hiccups are associated with significant morbidity. Herein, we present a rare and interesting case of coronavirus disease 2019 (COVID-19) induced persistent hiccups in a 61-year-old gentleman with no signs or symptoms of gastric pathology. As the patient required less oxygen supplementation, with inflammatory markers down-trending, his hiccups improved. The timeline of the symptom presentation and his response to treatment highly suggested that his hiccups were associated with COVID-19 infection. To the best of our knowledge, there are only two cases of persistent hiccups secondary to COVID-19 that have been reported thus far. Our case will add to the existing literature and highlight the potential association of COVID-19 with hiccups.

Sensory Axonopathy Associated With Vitamin E Deficiency

Vitamin E deficiency can be observed in patients with malabsorption syndromes or inherited diseases such as ataxia. It is unusual for it to be a result of dietary insufficiency due to its presence in a wide variety of foods. Patients with vitamin E deficiency can present with neuromuscular disorders such as ataxia, hyporeflexia, spinocerebellar syndrome, as well as loss of vibration and proprioceptive sensation. Herein, we are presenting a case in which a previously healthy adult with no family history of genetic defects and malabsorption syndrome presented with a characteristic sensory axonopathy associated with vitamin E deficiency without any evidence of fat malabsorption. Patient reported a markedly improvement of symptoms after three-month supplementation of vitamin E. The unique part of this case was that the patient presented with neuropathic pain associated with vitamin E deficiency without any family history of inherited deficiency or any malabsorption syndrome.

533. Demographic and Prognostic Indicators in COVID-19 Patients with ESRD: A Single Center Retrospective Study

Background

The first reported case of COVID-19 in the United States was in January 2020 and has since become a pandemic spreading rapidly worldwide. There is limited data on the epidemiology and prognosis of COVID-19 in end stage renal disease (ESRD) patients on hemodialysis (HD). In this study we describe our experience with 39 such patients who contracted COVID-19 disease.

Methods

We conducted a retrospective hospital cohort study on patients ≥ 18 years old with ESRD on HD and confirmed COVID-19, who were admitted to our hospital between 03/15/2020 and 05/25/2020. Study individuals were recruited if they had a well-defined clinical outcome (discharged alive or expired). Demographic, clinical and laboratory data were reviewed and retrieved. Descriptive analysis, univariate and multivariate logistic regression methods were employed to describe the demographic and to identify prognostic markers associated with mortality.

Results

Out of the 427 confirmed COVID-19 hospitalized patients during the study period, 39 ESRD patients on HD were included in this study, 19 (49%) expired, and 20 (51%) were discharged alive. Demographic analysis was tabulated in Table 1.

The non-parametric analysis showed a significant difference in ethnicity, history of COPD, need of mechanical ventilation, ferritin, LDH, lymphocyte-ferritin ratio (LFR), lymphocyte-CRP ratio (LCR) and AST/ALT ratio between survival and non-survival groups (Table 1, 2). Mechanical ventilation is independently associated with mortality in ESRD patients with COVID-19 (odds ratio [OR] 21.11; 95% confidence interval [CI], 3.00–238.9). In addition, low AST/ALT ratio has an odd of survival in this group of patients (OR 0.45; 95% CI, 0.19–0.88).

Table 1: Demographic Analysis of all ESRD patients with COVID-19. (HTN – Hypertension, DM – Diabetes mellitus, CAD – Coronary artery disease, CHF – Congestive heart failure, COPD – Chronic obstructive pulmonary disease)

Conclusion

Our observation of COVID-19 disease in patients with ESRD on HD confirms that this population is at the highest risk for mortality from SARS-CoV-2 infection, and that a low AST/ALT ratio is independently associated with decreased mortality, while mechanical ventilation had an increased mortality. Larger prospective studies in this population may help us understand better those prognostic markers and suggest how to intervene in order to decrease this catastrophic rate of mortality

360. A Case Control Study of COVID-19 in Patients with End Stage Renal Disease (ESRD)

Background

COVID-19 is a major global pandemic. Since the first case reported in Wuhan, China, COVID-19 has spread across the globe with more than 7.6 million individuals affected worldwide. Several studies have tried to investigate the risk factors for mortality but there has bot been a definitive study in patients with ESRD. Herein, we aimed to investigate whether ESRD is associated with mortality as compared to age, gender and comorbidities matched cohorts.

Methods

A retrospective case control study was performed on patients 18-year-old with confirmed SARS-CoV-2 admitted to our hospital during the study period (03/15/2020 to 05/15/2020). Demographic, characteristics and clinical outcome were retrieved and reviewed. We found 39 ESRD patients, we matched them for 5 variables: Age, gender, diabetes mellitus (DM), hypertension (HTN), and body mass index (BMI). Age was stratified into 3 groups (&lt; 30, 30 to 60, &gt;60), history of DM and HTN were defined by reviewing the admission medications, and BMI was divided into 2 categories (&lt; 30 and 30 kg/m2). The primary endpoint was percentage of inpatient mortality.

Results

We had 39 ESRD patients with COVID-19 out of the 400 patients admitted during the study period with known clinical outcome. Nineteen patients (49%) were between 30 to 60 years old while the rest (51%) were older than 60 years old. As for gender, 25 (64%) were males and 14 (36%) females. Additional comorbidities were present in 38 patients with hypertension (92%) being the most common, followed by DM (64%) and BMI &gt;30 kg/m2 (49%). With the 5 variables, we were able to match with 177 controls.

Nineteen individuals expired out of the 39 ESRD patients (49%), as compared to 46 patients from the 177 matched cohort (26%) (z-score 2.80, p=0.0051; odds ratio [OR], 2.71; 95% confidence interval [CI], 1.28–5.41).

Conclusion

Our results suggest that ESRD patients is an independent risk factor for increased mortality in patients with COVID 19 disease. Larger prospective studies will need to confirm this finding and try to find ways to mitigate this very high mortality in this vulnerable population.

552. Could Anticoagulant Use Prior to Infection with COVID-19 Decrease Mortality?

Background

The novel coronavirus (COVID-19) has resulted in substantial morbidity and mortality worldwide. Infection with COVID-19 has been associated with coagulopathy and inflammation. This prothrombotic state has been identified in the literature as an indicator of poor prognosis and those with COVID-19 who receive anticoagulation therapy may have better outcomes. Due to this prothrombotic state, patients who are currently receiving anticoagulation therapy for other indications prior to infection with COVID-19 may have better outcomes.

Methods

This was a retrospective case control study conducted at an inner city hospital. Patients were eligible if they were hospitalized between March 15, 2020 and May 15, 2020 and had confirmed infection due to COVID-19. Patients were matched by age, sex, body mass index (BMI), diabetes mellitus (DM), hypertension (HTN) and estimated glomerular filtration rate (eGFR) by chronic kidney disease (CKD) state. This study evaluated morality in patients who were receiving long term anticoagulation therapy prior to infection with COVID-19 compared to those who were not.

Results

Of the 436 patients hospitalized with confirmed infection due to COVID-19, 400 were eligible for analysis. Twenty-two were on anticoagulation therapy prior to admission. Among those patients, 68% were male and 32% were female. The majority of the patients were greater than 60 years of age (82%). Comorbidities were present in 21 patients and were as follows: HTN (95%), CKD (67%), DM (57%), obesity (36%). Of the 22 patients, five expired due to COVID-19 infection compared to 52 patients from the 149-patient matched cohort [z-score 1.13, p = 0.26; odds ratio (OR) 1.82; 95% confidence interval [CI], 0.69–4.71].

Conclusion

Prior long-term anticoagulation use does not appear to have a protective effect in patients with COVID-19 infection. Studies with larger sample size will be needed to answer this important question.

361. A Case Control Study of COVID-19 Outcome in Patients with HIV

Background

Little is known regarding outcome of patients living with HIV (PLWH) when they get admitted to a hospital for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. We decided to conduct a case-controlled study to try to answer the question if PLWH are at higher risk of mortality compared to individuals without HIV infection but with the same risk factors that affects outcome in COVID-19 disease.

Methods

A retrospective case matched control study was performed from 03/15/2020 to 05/15/2020. We reviewed all confirmed SARS-CoV-2 infected patients who were admitted to our hospital during the study period and retrieved 7 variables: Age, gender, diabetes mellitus (DM), hypertension (HTN), body mass index (BMI), chronic kidney disease (CKD), HIV status. We divided the age in 3 groups (< 30, 30 to 60, > 60), we defined the presence of DM and HTN by reviewing the admission medications, BMI > 30 defined obesity, and CKD was present if eGFR < 45 ml/min prior to the current admission. We found 12 PLWH, we matched them for the 6 variables, we found 94 controls. The primary endpoint was percentage of inpatient mortality.

Results

Of the 436 confirmed SARS-CoV-2 infection admitted between 03/15/20 and 05/15/20, 36 were still hospitalized. Twelve were PLWH out of the 400 patients with known outcome; 7 patients (58%) have the age range between 30 to 60 years old while the rest (42%) have age > 60 years old. Male to female ratio was 1:1 (6 patients each). Comorbidities were present in 10 patients (83%) with HTN (83%) being the most common, followed by CKD (58%), obesity (33%), and DM (33%).

Only 1 patient expired out of the 12 PLWH (8%) admitted with COVID-19, as compared to 26 patients from the 98 matched cohort (27%) (z-score 1.38, p=0.17; odds ratio [OR], 3.972; 95% confidence interval [CI], 0.62–44.37).

Conclusion

Our study suggests that PLWH do not have a worse prognosis than their matched controls for the most significant comorbid conditions affecting outcome in COVID-19 disease. Further studies with a larger sample size are urgently needed to confirm this finding.

60. New Prognostic Markers for COVID-19 Disease

Background

A few COVID-19 related retrospective studies have established that older age, elevated neutrophil-lymphocyte ratio (NLR), and decreased lymphocyte-CRP ratio (LCR) were associated with worse outcome. Herein, we aim to identify new prognostic markers associated with mortality.

Methods

We conducted a retrospective hospital cohort study on patients ≥ 18 years old with confirmed COVID-19, who were admitted to our hospital between 03/15/2020 and 05/25/2020. Study individuals were recruited if they had a complete CBC profile and inflammatory markers such as CRP, ferritin, D-dimer and LDH, as well as a well-defined clinical outcomes (discharged alive or expired). Demographic, clinical and laboratory data were reviewed and retrieved. Univariate and multivariate logistic regression methods were employed to identify prognostic markers associated with mortality.

Results

Out of the 344 confirmed COVID-19 hospitalized patients during the study period, 31 who did not have a complete blood profile were excluded; 303 patients were included in the study, 89 (29%) expired, and 214 (71%) were discharged alive. Demographic analysis was tabulated in Table 1.

The univariate analysis showed a significant association of death with absolute neutrophil count (ANC, p=0.022), NLR (p=002), neutrophil-monocyte ratio (NMR, p=< 0.0001), LCR (p=0.007), lymphocyte-LDH ratio (LLR, p=< 0.0001), lymphocyte-D-dimer ratio (LDR, p=< 0.0001), lymphocyte-ferritin ratio (LFR, p=< 0.0001), and platelets (p=0.037) with mortality. With multivariable logistic regression analysis, the only values that had an odds of survival were high LDR (odds ratio [OR] 1.763; 95% confidence interval [CI], 1.20–2.69), and a high LFR (OR 1.136, CI 1.01–1.34).

We further build up a model which can predict >85% mortality in our cohorts with the utilization of D-dimer (>500 ng/ml), Ferritin (>200 ng/ml), LDR (< 1.6), LFR (< 4) and ANC (>2.5). This new model has a ROC of 0.68 (p< 0.0001).

Conclusion

This retrospective cohort study of hospitalized patients with COVID-19 suggests LDR and LFR as potential independent prognostic indicators. A new model with combination of D-dimer, Ferritin, LDR, LFR and ANC, was able to predict >85% mortality in our cohort with ROC of 0.68, it will need to be validated in a prospective cohort study.

63. Prognosis of COVID-19 Patients with Diabetic Ketoacidosis with or Without Hyperosmolar Hyperglycemic State

Background

One of the risk factors for poor outcome with SARS-CoV-2 infection is diabetes mellitus; diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) are the most serious complications of diabetes mellitus. We aimed to explore the clinical characteristics and outcomes of COVID-19 patients presenting with isolated DKA or combined DKA/HHS to our institution.

Methods

A retrospective, hospital based observation case series was performed on patients with SARS-CoV-2 admitted to Intensive Care Unit between 03/20/20 and 04/20/20. Inclusion criteria were: 1) Blood Glucose &gt;250mg/dL; 2) Serum bicarbonate &lt; 18 mmol/L; 3) Anion Gap &gt;10; 4) serum pH &lt; 7.3; 4) ketonemia or ketonuria; and 5) positive SARS-CoV-2 RT-PCR. Hyperosmolality, on the other hand, was defined as an effective/calculated plasma osmolality &gt;304 mOsm/kg.

Results

A total of 87 patients with COVID-19 were admitted to the ICU during the study period, 12 of them had either isolated DKA or DKA/HHS. Baseline demographics, lab values and outcome are summarized in Table 1. Six of the patients had isolated DKA and six had combined DKA and HHS. The median age for the patient was 49.5 years old (range from 19 to 62 years old). The male to female ratio was 5:1. Of the 12 patients, 10 patients (83%) had a history of DM, nine were type 2 and only one type 1; two patients were newly diagnosed DM, presenting as DKA, presumptively precipitated by COVID-19. Five patients (42%) had a BMI &gt;30 kg/m2. As for ethnicity; seven were Hispanic (59%), four African American (33%), and one Caucasian (8%).

Patients with combined DKA/HHS, higher BMI, higher HbA1c, severe acidosis tended to have higher mortality. The striking feature was that isolated DKA or combined DKA/HHS was the initial presentation for COVID-19 for most of the cases.

Table 1: Demographic characteristic, inflammatory markers and outcome.

Conclusion

Our observational retrospective case series reinforces the need to watch for new onset DM and monitor blood sugar closely in those with known diabetes mellitus during SARS-CoV-2 infection, in order to avoid such serious complications as DKA and HHS.

387. Markers for Mortality in COVID-19 Patients with Atrial Fibrillation or Flutter

Background

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection can lead to many different cardiovascular complications, we were interested in studying prognostic markers in patients with atrial fibrillation/flutter (A. Fib/Flutter).

Methods

A retrospective cohort study of patients with confirmed COVID-19 and either with existing or new onset A. Fib/Flutter who were admitted to our hospital between March 15 and May 20, 2020. Demographic, outcome and laboratory data were extracted from the electronic medical record and compared between survivors and non-survivors. Univariate and multivariate logistic regression were employed to identify the prognostic markers associated with mortality in patients with A. Fib/Flutter

Results

The total number of confirmed COVID-19 patients during the study period was 350; 37 of them had existing or new onset A. Fib/Flutter. Twenty one (57%) expired, and 16 (43%) were discharged alive. The median age was 72 years old, ranged from 19 to 100 years old. Comorbidities were present in 33 (89%) patients, with hypertension (82%) being the most common, followed by diabetes (46%) and coronary artery disease (30%).

New onset of atrial fibrillation was identified in 23 patients (70%), of whom 13 (57%) expired; 29 patients (78%) presented with atrial fibrillation with rapid ventricular response, and 2 patients (5%) with atrial flutter. Mechanical ventilation was required for 8 patients, of whom 6 expired.

In univariate analysis, we found a significant difference in baseline ferritin (p=0.04), LDH (p=0.02), neutrophil-lymphocyte ratio (NLR) (p=0.05), neutrophil-monocyte ratio (NMR) (p=0.03) and platelet (p=0.015) between survivors and non-survivors. With multivariable logistic regression analysis, the only value that had an odds of survival was a low NLR (odds ratio 0.74; 95% confidence interval 0.53–0.93).

Conclusion

This retrospective cohort study of hospitalized patients with COVID-19 demonstrated an association of increase NLR as risk factors for death in COVID-19 patients with A. Fib/Flutter. A high NLR has been associated with increased incidence, severity and risk for stroke in atrial fibrillation patients but to our knowledge, we are first to demonstrate the utilization in mortality predictions in COVID-19 patients with A. Fib/Flutter.
