BMJ Case Rep 2021 Apr 27;14(4). Epub 2021 Apr 27.

Respiratory Medicine, Sandwell and West Birmingham Hospitals NHS Trust, Birmingham, UK.

Pneumocystis jirovecii pneumonia (PCP) is a potential life-threatening pulmonary infection which commonly manifests in immunosuppressed patients especially with HIV, with underlying malignancies, severe malnutrition as well as those on immunosuppressive treatments. There have been case reports of symptomatic PCP in individuals with a normally functioning immune system with typical clinical features and radiologic findings of bilateral and diffuse interstitial opacities. However, PCP in immunocompetent individuals presenting with lung nodules had been rarely reported. Read More

pneumonia, a COVID-19 mimic, reminds us of the importance of HIV testing in COVID-19.

Clin Med (Lond) 2020 11;20(6):590-592

University of Liverpool, Liverpool, UK and Royal Liverpool Hospital, Liverpool, UK

While clinical environments are highly focused on COVID-19, reports of missed or delayed treatment for conditions that imitate COVID-19, such as pneumonia caused by the fungus , are emerging. Given the uncertain spectrum of COVID-19 presentations and variable sensitivity of laboratory tests for SARS-CoV-2, there is a risk that, without a high index of suspicion, alternative aetiologies may be overlooked while pursuing a diagnosis of COVID-19. The British HIV Association has been calling for the inclusion of HIV testing in all patients admitted to hospital with suspected COVID-19. Read More

Veno-Venous Extracorporeal Membrane Oxygenation for Severe Pneumocystis jirovecii Pneumonia in an Immunocompromised Patient without HIV Infection.

Tohoku J Exp Med 2020 04;250(4):215-221

Department of Respiratory Medicine and Infectious Diseases, Oita University Faculty of Medicine.

Pneumocystis jirovecii pneumonia (PJP) occurs in immunocompromised hosts and is classified as PJP with human immunodeficiency virus (HIV) infection (HIV-PJP) and PJP without HIV infection (non-HIV PJP). Non-HIV PJP rapidly progresses to respiratory failure compared with HIV-PJP possibly due to the difference in immune conditions; namely, the prognosis of non-HIV PJP is worse than that of HIV PJP. However, the diagnosis of non-HIV PJP at the early stage is difficult. Read More

Serum Soluble Interleukin-2 Receptor Is a Biomarker for Pneumocystis jirovecii Pneumonia among Patients with Rheumatoid Arthritis under Methotrexate Therapy.

Tohoku J Exp Med 2019 07;248(3):209-216

Department of Respiratory Medicine, Nagasaki University Graduate School of Biomedical Sciences.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by systemic joint inflammation and may manifest as interstitial pneumonia (IP). Methotrexate (MTX) is one of the main therapeutic drugs used for RA, but MTX could cause severe side effects, including Pneumocystis jirovecii pneumonia (PCP) and IP. Owing to similar symptoms, it is sometimes difficult to discriminate MTX therapy-associated PCP (MTX-PCP) and MTX therapy-associated IP (MTX-IP). Read More

Pneumocystis jirovecii pneumonia at chest High-resolution Computed Tomography (HRCT) in non-HIV immunocompromised patients: Spectrum of findings and mimickers.

Eur J Radiol 2019 Jul 1;116:116-127. Epub 2019 May 1.

Institute of Radiology, Department of Medicine, University of Udine, Azienda Sanitaria Universitaria Integrata di Udine, p.le S. Maria della Misericordia 15, 33100, Udine, Italy. Electronic address:

Pneumocystis jirovecii pneumonia (PJP) has emerged as a main issue in non Human Immunodeficiency Virus (HIV) immunocompromised hosts, exposing patients to high mortality rates, especially when the diagnosis is delayed. Since microbiological confirmation is often unfeasible or difficult to obtain, High-resolution Computed Tomography (HRCT) represents a main tool for guiding the diagnosis in the appropriate clinical scenario. Nevertheless, radiologists must be aware that PJP at HRCT is a multifaceted process, with a variety of common and less frequent findings, along with a broad spectrum of infectious (e. Read More

Managing Pulmonary Toxicities Associated with Immunotherapy: A Case Discussion.

Oncologist 2019 06 21;24(6):730-734. Epub 2019 Mar 21.

Columbia University Medical Center, New York New York, USA

Immunotherapy has changed the field of oncology around the world with the approval of immune checkpoint inhibitors for a number of tumor types over the last 5 years. However, immune-mediated adverse events can be challenging and difficult to treat, with one of the most dire consequences being immune-mediated pneumonitis. KEY POINTS: Rapid intervention and aggressive management for grade 3 or greater pneumonitisSlow taper of steroids and also recommend pneumocystis carinii pneumonia prophylaxisMonitor carefully for a pneumonitis flare with steroid taper, which can occur in the absence of resuming anti-programmed cell death protein 1 (PD-1) [1], and do not resume anti-PD-1 therapy until completely off steroids and no clinical or radiologic evidence of recurrenceConsider observation without anti-PD-1 resumption-in this case, durable response was maintained even without resuming anti-PD-1 therapy.
