Item Open Access An international perspective on hospitalized patients with viral community-acquired pneumonia.(European journal of internal medicine, 2019-02) Radovanovic, Dejan; Sotgiu, Giovanni; Jankovic, Mateja; Mahesh, Padukudru Anand; Marcos, Pedro Jorge; Abdalla, Mohamed I; Di Pasquale, Marta Francesca; Gramegna, Andrea; Gramegna, Andrea; Terraneo, Silvia; Blasi, Francesco; Santus, Pierachille; Aliberti, Stefano; Reyes, Luis F; Restrepo, Marcos I; GLIMP Study GroupBackground
Who should be tested for viruses in patients with community acquired pneumonia (CAP), prevalence and risk factors for viral CAP are still debated. We evaluated the frequency of viral testing, virus prevalence, risk factors and treatment coverage with oseltamivir in patients admitted for CAP.Methods
Secondary analysis of GLIMP, an international, multicenter, point-prevalence study of hospitalized adults with CAP. Testing frequency, prevalence of viral CAP and treatment with oseltamivir were assessed among patients who underwent a viral swab. Univariate and multivariate analysis was used to evaluate risk factors.Results
553 (14.9%) patients with CAP underwent nasal swab. Viral CAP was diagnosed in 157 (28.4%) patients. Influenza virus was isolated in 80.9% of cases. Testing frequency and viral CAP prevalence were inhomogeneous across the participating centers. Obesity (OR 1.59, 95%CI: 1.01-2.48; p = 0.043) and need for invasive mechanical ventilation (OR 1.62, 95%CI: 1.02-2.56; p = 0.040) were independently associated with viral CAP. Prevalence of empirical treatment with oseltamivir was 5.1%.Conclusion
In an international scenario, testing frequency for viruses in CAP is very low. The most common cause of viral CAP is Influenza virus. Obesity and need for invasive ventilation represent independent risk factors for viral CAP. Adherence to recommendations for treatment with oseltamivir is poor.Item Open Access Prevalence and Etiology of Community-acquired Pneumonia in Immunocompromised Patients.(Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2019-04) Di Pasquale, Marta Francesca; Sotgiu, Giovanni; Gramegna, Andrea; Gramegna, Andrea; Radovanovic, Dejan; Terraneo, Silvia; Reyes, Luis F; Rupp, Jan; González Del Castillo, Juan; Blasi, Francesco; Aliberti, Stefano; Restrepo, Marcos I; GLIMP InvestigatorsBackground
The correct management of immunocompromised patients with pneumonia is debated. We evaluated the prevalence, risk factors, and characteristics of immunocompromised patients coming from the community with pneumonia.Methods
We conducted a secondary analysis of an international, multicenter study enrolling adult patients coming from the community with pneumonia and hospitalized in 222 hospitals in 54 countries worldwide. Risk factors for immunocompromise included AIDS, aplastic anemia, asplenia, hematological cancer, chemotherapy, neutropenia, biological drug use, lung transplantation, chronic steroid use, and solid tumor.Results
At least 1 risk factor for immunocompromise was recorded in 18% of the 3702 patients enrolled. The prevalences of risk factors significantly differed across continents and countries, with chronic steroid use (45%), hematological cancer (25%), and chemotherapy (22%) the most common. Among immunocompromised patients, community-acquired pneumonia (CAP) pathogens were the most frequently identified, and prevalences did not differ from those in immunocompetent patients. Risk factors for immunocompromise were independently associated with neither Pseudomonas aeruginosa nor non-community-acquired bacteria. Specific risk factors were independently associated with fungal infections (odds ratio for AIDS and hematological cancer, 15.10 and 4.65, respectively; both P = .001), mycobacterial infections (AIDS; P = .006), and viral infections other than influenza (hematological cancer, 5.49; P < .001).Conclusions
Our findings could be considered by clinicians in prescribing empiric antibiotic therapy for CAP in immunocompromised patients. Patients with AIDS and hematological cancer admitted with CAP may have higher prevalences of fungi, mycobacteria, and noninfluenza viruses.
