# Pneumocystis Pneumonia in a Non-AIDS Patient

## TL;DR

This paper reports a rare case of Pneumocystis pneumonia in a non-AIDS HIV patient, highlighting the importance of considering this condition in patients with lung symptoms.

## Contribution

The novelty lies in documenting PCP in a non-AIDS HIV patient, expanding the understanding of PCP susceptibility beyond traditional criteria.

## Key findings

- PCP can occur in non-AIDS HIV patients with certain CD4 T-cell counts.
- PCP should be considered in the differential diagnosis for HIV patients with acute lung disease.
- Comorbidities may influence PCP risk in HIV patients outside of AIDS.

## Abstract

We present a unique case of Pneumocystis jirovecii pneumonia (PCP) in a patient with HIV. Both treated and untreated HIV patients are susceptible to opportunistic pathogens. Depending on the patient’s underlying cluster of differentiation 4 T-cell (CD4 T-cell) count, HIV is associated with a wide range of infections. Historically, PCP has been observed in HIV patients with AIDS or in those receiving immunosuppressive therapy. However, it should remain a differential diagnosis in patients who present with comorbidities and symptoms of acute lung disease.
