ABSTRACT

BACKGROUND: Pneumocystis jirovecii pneumonia (PJP) and pulmonary cytomegalovirus (CMV) infection are common opportunistic infections among immunocompromised patients. However, few studies have evaluated their co-infection, especially among non-HIV patients. Therefore, we aimed to evaluate the outcomes and prognostic factors among non-HIV patients with PJP according to their CMV infection status. METHODS: This retrospective study evaluated non-HIV patients who were diagnosed with PJP between January 2009 and January2016.The patients were classified and compared according to their pulmonary CMV infection status (positive infection: bronchoalveolar lavage fluid [BALF] CMV DNA loads of >500copies/mL). RESULTS: Among 70 non-HIV patients with PJP, we identified 38 patients (54.3%) with pulmonary CMV infection. There was no significant difference in the mortality rates for the two groups (p = 0.15). Pulmonary CMV infection was significantly more common among patients who were receiving glucocorticoids and immunosuppressants, compared to corticosteroids only (p = 0.02). Pulmonary CMV infection was also significantly associated with severe dyspnea, a lower PaO2/FiO2, and the presence of centrilobular nodules (p = 0.008). Higher CMV DNA loads in the BALF were positively associated with mortality (p = 0.012). CONCLUSIONS: Combined therapy using corticosteroids and other immunosuppressants may be a risk factor for pulmonary CMV co-infection among patients with PJP. In addition, CMV pneumonia should be considered when centrilobular nodules and/or severe hypoxemia are observed in non-HIV patients with PJP. Furthermore, antiviral treatment should be promptly initiated for patients with a high CMV DNA load in BALF, based on their poor prognosis. More... »

    "description": "BACKGROUND: Pneumocystis jirovecii pneumonia (PJP) and pulmonary cytomegalovirus (CMV) infection are common opportunistic infections among immunocompromised patients. However, few studies have evaluated their co-infection, especially among non-HIV patients. Therefore, we aimed to evaluate the outcomes and prognostic factors among non-HIV patients with PJP according to their CMV infection status.\nMETHODS: This retrospective study evaluated non-HIV patients who were diagnosed with PJP between January 2009 and January2016.The patients were classified and compared according to their pulmonary CMV infection status (positive infection: bronchoalveolar lavage fluid [BALF] CMV DNA loads of >500copies/mL).\nRESULTS: Among 70 non-HIV patients with PJP, we identified 38 patients (54.3%) with pulmonary CMV infection. There was no significant difference in the mortality rates for the two groups (p\u00a0=\u00a00.15). Pulmonary CMV infection was significantly more common among patients who were receiving glucocorticoids and immunosuppressants, compared to corticosteroids only (p\u00a0=\u00a00.02). Pulmonary CMV infection was also significantly associated with severe dyspnea, a lower PaO2/FiO2, and the presence of centrilobular nodules (p\u00a0=\u00a00.008). Higher CMV DNA loads in the BALF were positively associated with mortality (p\u00a0=\u00a00.012).\nCONCLUSIONS: Combined therapy using corticosteroids and other immunosuppressants may be a risk factor for pulmonary CMV co-infection among patients with PJP. In addition, CMV pneumonia should be considered when centrilobular nodules and/or severe hypoxemia are observed in non-HIV patients with PJP. Furthermore, antiviral treatment should be promptly initiated for patients with a high CMV DNA load in BALF, based on their poor prognosis.",
