Pneumocystis jirovecii Pneumonia (PJP) • Review the clinical presentation and prophylaxis for the
disease
• Identify risk factors and susceptible patients for PJP • Explore clinical studies comparing the efficacy and safety
of PJP prophylaxis in HIV-negative and non-chemotherapy patients

Should Pneumocystis jiroveci Pneumonia (PJP) prophylaxis be initiated?
a) YES
b) NO

Patient Case
• GA is a 34 year-old female who presents to the emergency
department with right ear pain/abscess. A moderate amount of fluid was drained surgically and the patient was discharged on ciprofloxacin 500 mg twice daily for 7 days with next-day ENT referral.
• After 3 days, GA starts to experience pain in her jaw (bilateral), right elbow, right neck, hips, knees and 2-3 hours of morning stiffness in left hand. Imaging showed nodules on left ear and nasal septum.
• GA was admitted to the hospital for suspected relapsing polychondritis, for which she was started on methylprednisolone 1 gram IV daily and oral methotrexate 15 mg weekly

Pneumocystis (carinii) jiroveci Pneumonia (PJP)
• Carlos Chagas first to discover cystic forms of Pneumocystis in 1909
• In 1910, Antonio Carini found similar cystic forms in the lungs of rats - named Pneumocystis carinii
• In the 1940s, Pneumocystis was linked to pneumonia in premature and malnourished infants
• In 1952, Otto Jirovec identified this organism as the causative agent of interstitial pneumonia in infected infants
• In 1980s, PJP became more prevalent with the widespread of human immunodeficiency virus (HIV)

Epidemiology
• PJP was the most common opportunistic infection in the years 2008-2010
• CDC reports near 40% of PJP patients are HIV positive and 60% are immunocompromised due to other states
• Mortality rates reported in Non-HIV (nHIV) patients range between 30-50%, compared to 10-12% in HIV patients
• Up to 20% of adults could be carriers at any given point without any symptoms
• Eradication by healthy immune system could take several months

Tasaka S, Tokuda H. J Infect Chemother. 2012;18(6):793-806. 8
Pathophysiology
• The trophic form of Pneumocystis jiroveci attaches to the alveoli
and replicates freely under immune suppression
• Macrophages are unable to eradicate these organisms without CD4+ cells
• Inflammatory response leads to symptoms of: • Hypoxemia • Respiratory alkalosis • Impaired diffusing capacity • Changes in vital capacity • Respiratory failure
Tasaka S, Tokuda H. J Infect Chemother. 2012;18(6):793-806.
9
Diagnosis: Imaging
• Chest radiography (CXR)
• Diffuse bilateral infiltrates
• Chest high-resolution computed tomography scan (CT)
• Bilateral ground-glass opacities
Tasaka S, Tokuda H. J Infect Chemother. 2012;18(6):793-806. Salzer HJF. Respiration. 2018;96(1):52-56. 12
Clinical Presentation
• PJP in HIV patients presents gradually and progresses to
respiratory failure in 2 weeks - 2 months • Easier to diagnose in HIV patients due to larger fungal load in lungs
• PJP in nHIV* (immunocompromised) patients has an abrupt onset and progresses to respiratory failure in 1 week
• Respiratory insufficiency is more severe in nHIV patients • More severe inflammatory response in nHIV patients (more
bronchoalveolar neutrophils)
• Other symptoms include: • Fever and non-productive cough (HIV = nHIV) • Chest pain (HIV > nHIV) • Weight loss (HIV > nHIV)
*Includes transplant and chemotherapy patients

Background
• Pneumocystis organisms are fungi that were initially classified as a
protozoa due to different forms • Lack of ergosterol and difficult to be cultured
• Three distinct morphological stages: trophic form (clusters), pre- cystic form (sporozoite) and cyst form (spores)
• Pneumocystis organisms are commonly found in healthy lungs with earliest exposures reported by age 4 years
• Pneumocystis organisms are communicable via airborne transmission
• Pneumonia occurs when both cellular and humoral immunity are defective

Schmajuk et al.
• Authors’ interpretation:
• Incidence rate of PJP in the non-prophylaxis group was 3.7/375 patient-years (1% per year)
• Findings show efficacy of selective use of PJP prophylaxis in high-risk diagnoses and immunosuppressants
• Due to significant rate of adverse events (2.2% per year), PJP prophylaxis should be personalized
• Limitations: • Excluding antibiotic prescription ordered for less than 30 days (29
patients) • Single center without a standard diagnostic process

Summary of Literature

Study Risk Population (nHIV) PJP Prophylaxis Recommended?
Fillatre et al. Inflammatory diseases, vasculitis
Only in vasculitis (GPA,PAN) & PM/DM
Schmajuk et al.
GPA, PM, DM, SLE
No
Yukawa et al.
RA Only for scores 5 and
above
Metraiah et al.
AAV Yes (induction and maintenance)
Long et al.
IBD
Depends on other factors
Long et al.
• Authors’ Interpretation
• IBD increases risk of developing PJP • Despite increased relative risk of PJP in IBD, the absolute risk remains low
• NNT estimated to be between 2070 to 2952 for immunosuppressant use alone
• Other risk factors must be considered before initiating prophylaxis
• Limitations • Patients older than 65 and uninsured patients were not represented in this
study
• Study does not take into account the number of immunosuppressants
Long MD, et al. Inflamm Bowel Dis. 2013;19(5):1-13.
38
Conclusion
• Immunosuppression is key in developing PJP
• Initiating PJP prophylaxis should be based on all risk factors present in the patient
• More studies are needed to evaluate the severity of each risk factor
• In some disease states, such as rheumatoid arthritis and systemic lupus erythematosus, risks may outweigh the benefit of PJP prevention
• In high-risk disease states, such as vasculitis, prophylaxis may be necessary
41
Future Direction
• Lack of randomized controlled trials is impeding implementation
of new recommendations into practice guidelines
• Comparing safety and efficacy of different prophylaxis regimens in the nHIV population
• PJP risk does not take into account other important factors, such as patient-level differences in drug metabolism
• Pharmacy involvement to help individualize PJP prophylaxis based on patient-specific attributes
42
• GA is a 34 year-old female admitted for relapsing polychondritis with lymphocytopenia
• GA has a complex
autoimmune disorder (PR3+)
• GA is on cyclophosphamide,
prednisone and methotrexate
• Multiple readmissions for
abscess and ear pain
40
Back to GA
• Do you recommend starting PJP prophylaxis?
• YES • NO
Long et al.
• Primary outcome
• Incidence of PJP in IBD patients without HIV
• Results • Annual incidence of PJP of 10.6/100,000 patient years in IBD compared to
3.0/100,000 patient years in non-IBD (IRR = 3.48, 95% CI 2.10-5.81)
• In IBD cohort, annual incidence of PJP was higher in patients taking immunosuppressants than in those who were not (32/100,000 vs. 5.5/100,000 patient years)
• Risk for CD compared to non-IBD (IRR = 4.49, 95% CI 2.14-9.75) was greater
than risk for UC compared to non-IBD (IRR = 2.40, 95% CI 1.11-5.10)
• Incidence of PJP increased with age, with highest at 60+ years (32.8/100,000 patient years)
