Introduction: Besides the improvement we have had in the diagnostic methods, the causative agent in around 50% of the cases of community-acquired pneumonia (CAP) remains unknown, even in inpatients. Despite that, adequate empirical therapy results in low mortality in the majority of the cases. Goals: To describe the epidemiology, the clinical presentation, the utility of diagnostic tests, the duration of hospital stay, the morbidity and mortality rates of 42 consecutive inpatients with CAP. Methods: The inclusion criteria were the presence of a recent pulmonar infiltrate in the CXR and two items out of fever (38ºC), productive cough and leukocytosis (> 10,000/mm3), in the presence of a compatible clinical syndrome. The subsidiary tests were performed as required on individual basis. Results: Forty-two patients, aged 64.7 ± 16.8 years, 27 (64.3%) male, were studied. Twenty-seven (64%) had subjacent illness. Seventeen (40.5%) were on antimicrobial therapy on admission. There were eight cases (19%) of severe pneumonia; the patients aged > 60 or £ 60 years were similar concerning the severity of presentation (p = 0.57) and had similar hospital stay (p = 0.25). The mean global hospital stay was 14.3 ± 7.6 days. Definite etiologic diagnosis were done in three patients: Legionella sp (2), S. aureus (1). In thirty-one cases (73.8%) the antimicrobial therapy wasn't modified; when it happened (11 patients, 26.2%), the main reason was the bad outcome in six cases (54.5%); in five (45.5%), the microbiological result prompted the change in therapy. Blood samples were drawn in 16 cases (38%), being positive in only one (6.3%). There were nine adequate sputum samples for analysis (9/22, 41%). There was only one death (2.4%), due to severe pneumonia in a patient with a neoplastic disease. Conclusion: The etiologic diagnosis in CAP is reached in a minority of cases, even in inpatients. At least partly, this is probably due to the previous use of antimicrobial drugs. Adequate empirical therapy results in low mortality. Diagnostic tests can be performed on individual basis.

Objective: To investigate the correlation of HRCT findings with pulmonary metabolic activity in the corresponding regions using 18F-FDG PET/CT and inflammatory markers in patients with systemic sclerosis (SSc)-associated interstitial lung disease (ILD). Methods: This was a cross-sectional study involving 23 adult patients with SSc-associated ILD without other connective tissue diseases. The study also involved 18F-FDG PET/CT, HRCT, determination of serum chemokine levels, clinical data, and pulmonary function testing. Results: In this cohort of patients with long-term disease (disease duration, 11.8 ± 8.7 years), a nonspecific interstitial pneumonia pattern was found in 19 (82.6%). Honeycombing areas had higher median standardized uptake values (1.95; p = 0.85). Serum levels of soluble tumor necrosis factor receptor 1, soluble tumor necrosis factor receptor 2, C-C motif chemokine ligand 2 (CCL2), and C-X-C motif chemokine ligand 10 were higher in SSc patients than in controls. Serum levels of CCL2-a marker of fibroblast activity-were correlated with pure ground-glass opacity (GGO) areas on HRCT scans (p = 0.007). 18F-FDG PET/CT showed significant metabolic activity for all HRCT patterns. The correlation between serum CCL2 levels and GGO on HRCT scans suggests a central role of fibroblasts in these areas, adding new information towards the understanding of the mechanisms surrounding cellular and molecular elements and their expression on HRCT scans in patients with SSc-associated ILD. Conclusions: 18F-FDG PET/CT appears to be unable to differentiate the intensity of metabolic activity across HRCT patterns in chronic SSc patients. The association between CCL2 and GGO might be related to fibroblast activity in these areas; however, upregulated CCL2 expression in the lung tissue of SSc patients should be investigated in order to gain a better understanding of this association.
