Background:
To describe the clinical presentations, treatment regimen, and outcomes of Pneumocystis jiroveci pneumonia (PJP) among immunocompromised patients at King Faisal Specialist Hospital and Research Center in Saudi Arabia.
Materials And Methods:
In this retrospective cohort study, patients with a laboratory-confirmed diagnosis of PJP were included.
Results:
During the study, 42 patients with confirmed PJP were identified. Twenty (48%) patients were HIV-infected, while 22 (52%) were HIV negative. The median T-cell count (CD 4 ) was below 50 cells/mL in HIV patients with PJP at the time of HIV and PJP diagnoses. Graft rejection, cytomegalovirus (CMV) reactivation, and lymphopenia were associated with the development of PJP in transplant recipients; and high-dose steroids for non-transplant patients. The all-cause mortality at 90 days was lower in individuals with HIV-related PJP, compared to those with other predisposing conditions (10% and 32%, respectively; P=0.085). No specific risk factors were independently associated with the increased risk of mortality.
Conclusion:
PJP remains an important cause of morbidity and mortality in immunocompromised patients, with a higher mortality rate reported in non-HIV patients.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
