ABSTRACT
Introduction: Secondary infections are a known complication post viral respiratory infections. Secondary infections have always been significant cause of morbidity and mortality in previous well-studied influenza pandemics1. Aims and Objectives: We aimed to diagnose secondary infection early using indicated interventional procedures in post COVID-19 patients with persistent respiratory symptoms more than 4 weeks. Method(s): Post COVID-19 patients with persistent respiratory symptoms who presented to GHRI, Nagpur (India) during 2nd wave were selected for the study. Patients with persistent respiratory symptoms more than 4 weeks after recovering from COVID-19 infection and Radiological abnormality on either Chest X-ray or HRCT Chest were subjected to bronchoscopy or medical thoracoscopy as indicated. Result(s): A total of 72 patients with available culture reports were assessed. Persistent cough, fever and shortness of breath were present in 52.8%, 19.4% and 11.1% of patients respectively. We found evidence of respiratory infections in total 30.5% patients. 11.1% were found to be suffering from pulmonary (3 were drug resistant) and 2.8% from pleural tuberculosis. Also, 4.2% patients were found to be suffering from fungal and 12.5% patients from Bacterial and 6.9% of patients were found to be suffering from more than one infection. Conclusion(s): Meticulous follow up with indicated interventional procedures is useful and safe in diagnosing pulmonary infections early in post COVID-19 patients.

SESSION TITLE: Critical Care Presentations of TB SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/18/2022 12:25 pm - 01:25 pm INTRODUCTION: TNFα plays a pivotal role in inflammation and maintenance of immune response against tuberculosis. The use of TNF inhibitors (TNFi) is associated with a significant increase in the incidence of tuberculosis (TB). TNFi may cause drug-induced lupus (ATIL) presenting as constitutional symptoms, rashes, pericardial and pleural effusions with positive autoantibodies. We present a case of pleural TB masquerading as drug-induced lupus. CASE PRESENTATION: A 68y/o woman with a history of ulcerative colitis (on infliximab, mesalamine), hypertension, T2DM, CAD, complained of low-grade fever, rashes, left-sided chest pain, dyspnea, and arthralgias for two weeks. Chest pain- worse with inspiration and cough. She emigrated from India to the USA 40 years ago. Six months before infliximab therapy, Quantiferon gold was negative. Exam: faint hyperpigmentation over shins, minimal swelling of MCPs and ankles, dullness to percussion over the left chest with decreased breath sounds. Labs: CRP 101 mg/dL, Hb 10.8 iron deficient, rheumatoid factor and anti-CCP negative, ANA 1:40, dsDNA 1:640, a reminder of ENA negative, anti-histone negative, C3/C4 normal, UA bland, protein/Cr 0.4 mg/gm, negative blood cultures, SPEP and LDH normal. CXR: opacification of the left lung up to midfield. CT chest: moderate left and small right pleural effusions, enlarged mediastinal lymph nodes. COVID and Quantiferon: negative. Thoracentesis: 850 ml of exudative fluid (2 out of 3 Light's criteria), lymphocytic predominance (76% of 4148 nucleated cells), adenosine deaminase (ADA) 42 U/L, gram stain, culture, acid-fast and MTB PCR negative, cytology negative. Thoracoscopy with biopsy of the parietal pleura: necrotizing granulomatous pleuritis with acid-fast bacilli. Sensitivity: pan-sensitive M. tuberculosis. Sputum: negative for TB. She was discharged on RIPE treatment for reactivation of TB. DISCUSSION: The incidence of infliximab-induced lupus is approximately 0.19% and confirming the diagnosis is challenging. The immunogenicity of infliximab is high, 66% of patients develop positive ANA. Anti-histone antibodies are less commonly associated with ATIL as opposed to classic drug-induced lupus and dsDNA is positive in up to 90% of cases of ATIL. Renal involvement is rare. The diagnostic usefulness of ADA (over 40 U/L) in lymphocytic pleural effusions for the diagnosis of tuberculosis in an immunosuppressed individual is demonstrated here. In countries with low TB burden, such as the USA, the positive predictive value of ADA in pleural fluid declines but the negative predictive value remains high. CONCLUSIONS: Tuberculous pleuritis is not always easily diagnosed since AFB smears and sputum may remain negative. When ADA level in lymphocytic pleural fluid is not low thorough search for TB with thoracoscopy and biopsy is justified. Reference #1: Shovman O, Tamar S, Amital H, Watad A, Shoenfeld Y.

ABSTRACT
A 26-year-old man complained of shortness of breath for 3 days before the hospital admission. The patient had a history of coughing up blood and had consumed alcohol and drugs. Decreased vesicular auscultation and dull percussion in the left lateral pulmo. Laboratory result showed increased neutrophil-lymphocyte ratio C-reactive protein, D-dimer, procalcitonin, ferritin, and decreased albumin level. Pleural fluid analysis indicated the presence of exudate, SARS-CoV-2 PCR positive, and increased ADA level to 43 U/L. Based on the examination results, we suspected that the etiology of the massive pleural effusion was tuberculous pleurisy, particularly due to increased ADA levels. The patient was diagnosed with COVID-19 pneumonia with massive pleural effusion and tuberculous pleurisy. Massive pleural effusion in SARS-CoV-2 infection is rare. Thus, laboratory modalities for massive pleural effusion diagnosis are needed to determine the etiology and effective treatment for the patient. ADA analysis could be considered as an initial examination in patients with pleural effusion during the wait for pleural fluid culture results.
ABSTRACT
Background: Covid 19 and Tuberculosis are the infectious diseases primarily affecting the lung. Both of them present with cough, fever and difficulty in breathing but Tuberculosis has a longer incubation period and onset of disease is slower. The patients of Tuberculosis are more likely to have comorbidities (malnutrition, diabetes mellitus, Human Immunodeficiency Virus) that increases their vulnerability to covid-19. Aim: To study the clinical profile, course, management and outcome in patient presented with covid-19 and tuberculosis in covid pandemic in Mumbai. Methods: We studied the 323-patient admitted in covid Intensive Care Unit and ward who were proven covid 19 positives by Reverse Transcriptase Polymerase Chain Reaction, Cartridge Based Nucleic Acid Amplification Test or rapid antigen test. All patients were given standard medical care, ventilatory support if required as per covid19 protocol. The chest x-ray, blood investigation and sputum investigation were studied till the time of discharge or death. Results: Out of 323 patients studied 14 had Tuberculosis. Out of those 14 patients 10 patient had pulmonary tuberculosis, 3 had Tuberculous pleural effusion and one had abdominal tuberculosis. All of them had pneumonia on chest x-ray which can be attributed to covid-19 or Tuberculosis. Conclusion: In our study all 14 patients were survived and discharged. As there is high burden of tuberculosis the covid-19 only helped in exposing the tip of the iceberg of the grave problem of undiagnosed tuberculosis in community. It seems that there is just coincidental occurrence of tuberculosis and covid19 coinfection than a causal association.
ABSTRACT
A 33-year-old woman with a fever, cough, and pharyngitis was admitted after left-sided pleural effusion was detected. The fever and upper respiratory symptoms were confirmed, and she was diagnosed with coronavirus disease (COVID-19) after showing a positive polymerase chain reaction (PCR) test. After thoracentesis, pleural fluid revealed elevated adenosine deaminase values and a positive QuantiFeron test; tuberculous pleurisy was thus suspected. Subsequent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) PCR and anti-SARS-CoV-2 Spike IgG tests were negative, suggesting that the initial PCR result had been erroneous. However, we were unable to confirm this. Data concerning COVID-19 diagnostics are insufficient at present. It is important to make comprehensive judgments regarding the diagnosis and treatment of patients as well as public health.
