CRP and pneumocystosis: From the univariate analysis, the cumulative steroid dose received during the hospital stay (OR 1.004, 95%CI 1–1.008, p = 0.042) and the highest CRP value recorded during the hospitalization (OR 1.076, 95%CI 1.016–1.140, p = 0.012) were identified as risk factors for PJP, while SARS-CoV-2 vaccination with one (OR 0.269, 95%CI 0.083–0.877, p = 0.029) and two doses (OR 0.304, 95%CI 0.093–0.994, p = 0.049) was identified as a protective factor for PJP.
