SESSION TITLE: Systemic Disease with Diffuse Lung Symptoms Case Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: Since its first detection at Wuhan, China, SARS-CoV-2 (novel coronavirus 2019) has engulfed the world with more than 100 million cases and manifestations of COVID19 have been evolving over time. Various post COVID19 syndromes are being recognized. Reactive arthritis, connective tissue disorders such as myositis and pulmonary complications have been correlated with exposure to COVID infection. We describe the case of antisynthetase syndrome in a patient correlated with exposure to COVID infection or vaccine. CASE PRESENTATION: A 68 year old female with history of hypertension and exposure to COVID infection in the family member, presented with 2-3 months worsening generalized body ache/pain started 2 weeks after receiving second dose of mRNA vaccine. Patient also reported dyspnea and leg swelling for 1 month. Upon presentation, she was placed on 4 liter oxygen via nasal cannula. Chest x-ray concerning for infiltrates, possibly COVID. CT chest no pulmonary embolism but evidence of pneumonia superimposed on chronic appearing bronchiectasis. Flu and Covid testing were negative. Patient was started on IV antibiotics for community acquired pneumonia. Labs showed elevated ESR, CRP and CK level. No fever, weakness, mechanics hands, rash or Raynaud's phenomenon. Infectious work up remained negative. No lymphadenopathy on CT chest to suggest sarcoid. ACE level normal. ANA and anti aminoacyl-tRNA synthetase antibody positive but other ENA were negative. HMG-COA ab negative. MPO/PR3 neg. Echocardiogram was unremarkable. Work up was suggestive of Anti synthetase syndrome with interstitial lung disease(ILD), a form of dermatomyositis. Patient was started on intravenous steroid with good improvement in symptoms and later transitioned to oral prednisone. Patient was discharged on minimal home oxygen with plan to start immunosuppressive medications. DISCUSSION: We are unsure if our patient had COVID19 infection since COVID testings were negative (antigen, antibody and nucleic acid detection ). The likelihood of autoimmune and rheumatic diseases in COVID19 survivors is a big issue. COVID19 infection may unmask previously undiagnosed rheumatic conditions and precipitate de novo disease, both of which may persist after resolution of the initial infection. Corticosteroids remain the cornerstone of early treatment with initial doses at 1mg/kg of the ideal body weight. In an effort to reduce steroid related side effects, other immunosuppressive agents should be considered at the outset of therapy, particularly when treating anti-synthetase syndrome with manifestations of ILD. CONCLUSIONS: Patients with anti-synthetase syndrome with ILD could have correlation with exposure to COVID infection or vaccination, and are steroid responsive. It is likely that clinical improvement may result from prompt suppression of inflammatory systemic response by corticosteroid. Reference #1: 1. Ahmed S, Zimba O, Gasparyan AY.

ABSTRACT
SESSION TITLE: Procedures in Chest Infections Case Posters SESSION TYPE: Case Report Posters PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: Pneumonia is a common condition that is seen in hospitals. Pneumocystis Jirovecii is an opportunist fungal pathogen. Bordetella bronchiseptica is a gram negative bacteria that causes infectious bronchitis in dogs and other animals, but rarely infects humans. CASE PRESENTATION: Patient is a 34 year old African American female with history of sickle cell trait, reported Lupus (not on treatment), asthma, COVID pneumonia who was admitted for worsening shortness of breath & productive cough with yellow sputum. She was previously hospitalized and discharged after being treated for Community-Acquired Pneumonia. In the ER, she was febrile, tachycardic, tachypneic, & hypoxic requiring BiPAP. CXR obtained showed findings concerning for multifocal pneumonia. Chest CT Angiogram was negative for PE. Patient was started on Vancomycin & Meropenem for treatment of her pneumonia. Blood cultures, Legionella, Strep pneumoniae, Aspergillus, Beta-D-glucan, Sputum culture, & MRSA screen were ordered for further evaluation of her infection. ANA screen reflex panel, lupus anticoagulant, anticardiolipin antibodies, beta-2 glycoprotein antibodies were also ordered given patient's reported history of SLE and the concern for SLE pneumonitis: ANA & Sjogren's Anti-SSA were positive;otherwise, autoimmune workup was unremarkable. During hospitalization, patient was eventually weaned down to nasal cannula and antibiotic was de-escalated to levaquin. However, sputum culture eventually grew Bordetella Bronchiseptica that was resistant to Levaquin so antibiotic regimen was switched to Doxycycline. In addition, Beta-D-glucan was noted to be elevated. Bronchoscopy was done for further evaluation;multiple transbronchial biopsies were positive Pneumocystis Jirovecii. Patient was then initiated on Bactrim for treatment of PJP Pneumonia along with a steroid taper. Patient was tested for HIV and it was negative. DISCUSSION: In this case, patient was found to have two rare pathogens, that are more common in immunocompromised patients such as those with HIV/AIDS, on high-dose corticosteroids or malignancy. This patient had a unconfirmed diagnosis of SLE and past COVID Pneumonia. Patient had Bordetella bronchiseptica pneumonia that is frequently isolated in the respiratory tract of animals but can cause severe respiratory infection in humans. This microorganism can cause upper respiratory tract infections, pneumonitis, endocarditis, peritonitis, meningitis, sepsis and recurrent bacteremia. Upon further discussion with the patient, she was found to have a recent pet dog. CONCLUSIONS: High level of clinical suspicious is needed in patient presenting with recurrent pneumonia with chest imaging findings suggestive of multifocal pneumonia. The mainstay of treatment for PJP is TMP-SMX and steroid. We recommend Fluoroquinolones or tetracycline for Bordetella bronchiseptica pneumonia.
