RESUMO
Pneumonias are a major cause of morbidity and mortality and their prognosis depends on many factors including nutritional status. This study analyzed the relationship between malnutrition and the risk of death in Community Acquired Pneumonia (CAP) patients. This is a prospective observational study. The Subjective Global Assessment (SGA) was used as a screening tool to appraise the nutritional status. Ninety-eight patients with CAP requiring hospitalization were included consecutively from October 2004 to September 2006. The clinical, bacteriological and laboratory features were recorded. Patient's nutritional condition was assessed using the SGA. The monitoring was performed until discharge, death or shunt. Persistent cough or fever, the presence of pleural effusion, malignancies or long hospitalization were associated with worse prognosis. Mortality increased in proportion to the degree of malnutrition. Thirty two CAP patients (32.65%) were classified as SGA-category A; 44 (44.90%) as SGA-B, and 22 (22.45%) as SGA-C. Pneumonia resulted in death in 3/32 SGA-A (9.37%), 8/44 SGA-B (18.18%) and 10/22 SGA-C patients. SGA-C patients showed significantly higher odds ratios for death in comparison to SGA-A patients (OR = 6.085, CI95%: 1.071-34.591; p = 0.042). Considering death as the outcome variable, SGA-A class had the highest negative predictive value (0.906), while SGA-C class showed the highest positive predictive value (0.455). These results link the nutritional status to the NAC evolution prognostic. SGA provides a simple estimation of the nutritional status and it is a good predictor of the risk of death in CAP patients.

For better management of patients with febrile neutropenia, our study investigated the epidemiologic, microbiologic, and clinical characteristics of adult inpatients with febrile neutropenia and their mortality-associated factors. To this end, we carried out a prospective, observational, multicenter study in 28 Argentinian hospitals between 2007 and 2012. We included 515 episodes of febrile neutropenia from 346 patients, median age 49 years. Neutropenia followed chemotherapy in 77% of cases, half of the cases due to hematological malignancies. Most episodes were classified as high-risk according to MASCC criteria, and 53.6% of patients were already hospitalized at the onset of febrile neutropenia. Bloodstream infections were detected in 14% episodes; whereas an infectious source of fever was identified in 80% of cases. Mortality rate achieved to 14.95%. The binary regression analysis showed that persistence of fever at day 7, or neutropenia at day 14, dehydration and tachycardia at the onset of febrile neutropenia as well as prior infections were significantly associated with mortality. In addition to expanding our current knowledge on the features of adult patients with febrile neutropenia, present findings provide useful information for better management of them in Argentina, given the appropriate representativeness of centers participating in the study.

Las neumonías constituyen una causa mayor de morbimortalidad, y entre los factores de riesgo se incluye el estado nutricional. En el presente estudio se analizó la relación entre malnutrición y mortalidad en Neumonía Aguda de la Comunidad (NAC) y se utilizó la Escala de Evaluación Global Subjetiva (EGS) como método de valoración del estado nutricional de los pacientes con NAC. En este estudio prospectivo observacional se incluyeron en forma consecutiva 98 pacientes con NAC que requirieron hospitalización, de octubre de 2004 a septiembre de 2006. Se registraron características clínicas, bacteriológicas y de laboratorio y se evaluó nutricionalmente a cada paciente utilizando la EGS. El seguimiento se realizó hasta el alta médica, derivación o muerte. La persistencia de tos o fiebre, la presencia de derrame pleural, neoplasias o larga hospitalización se asociaron a peor pronóstico. La mortalidad aumentó proporcionalmente con el grado de desnutrición. Treinta y dos pacientes (32.65%) fueron clasificados como categoría EGS-A; 44 (44.90%) como EGS-B, y 22 (22.45%) como EGS-C. Fallecieron 3 de 32 EGS-A (9.37%), 8 de 44 EGS-B (18.18%) y 10 de 22 EGS-C. El riesgo de muerte fue significativamente mayor en el grupo EGS-C que en el EGS-A; OR = 6.085 (CI95% 1.071- 34.591) p = 0.042. Considerando la muerte como variable de egreso, la categoría EGS-A mostró el mayor valor predictivo negativo (0.906), y EGS-C el mayor valor predictivo positivo (0.455). La EGS realizada al ingreso fue un instrumento útil para identificar el estado nutricional y un buen pronosticador de riesgo de muerte en NAC.
