Pneumocystis jirovecii Pneumonia Mimicking COVID-19 Pneumonia In A Patient With Newly Diagnosed Advanced HIV Disease

Abstract

During the pandemic, diagnosis of COVID-19 infection must be excluded in patients presenting with respiratory features, especially in the area where the incidence was high. This case report highlights a man who came with respiratory infection symptoms and the chest radiograph suspicious of COVID-19 pneumonia; however, his swab test for RT-PCR was negative for COVID-19. Later he was found to have a positive anti-HIV antibody and developed advanced HIV infection by multiple opportunistic infections. A 45-year-old man presented with chronic cough and dyspnea for three months which worsened five days before the presentation. It was associated with diarrhoea, dysphagia, weight loss, left lower limb weakness, with bowel and urinary incontinence. Chest auscultation revealed generalized crepitations. The first chest radiograph showed bilateral reticular opacities extending to the lung peripheries when the suspected diagnosis of COVID-19 pneumonia was made. The nasopharynx swab for RT-PCR for COVID-19 was negative, and the sputum was Ulum Islamiyyah Journal | Special Issue: Healthcare in Pandemic Era: “The New Norm” Vol.1 108 positive for Pneumocystis jirovecii. The contrast-enhanced CT (CECT) brain revealed changes consistent with brain abscess. The cerebrospinal fluid (CSF) examination was consistent with cryptococcal infection. He was initially treated in the Severe Acute Respiratory Infection (SARI) ward because of the initial impression of COVID-19. He was tested positive for Human Immunodeficiency Virus (HIV) rapid test and PCR, RPR and TPHA for syphilis. He was diagnosed with Pneumocystis jirovecii pneumonia, cryptococcal meningitis, brain abscess, oral and oesophageal candidiasis and syphilis. He was treated with co-trimoxazole, Amphotericin B, flucytosine, fluconazole, penicillin G and Nystatin. He initially improved upon treatment but later succumbed to his illnesses. Given the current situation of COVID-19, any patient with acute respiratory symptoms must be tested to rule out COVID-19 pneumonia. However, in a newly diagnosed advanced HIV patient presented with respiratory infection symptoms and extrapulmonary symptoms, opportunistic infections should be excluded along with COVID-19.
