In this regard, we must bear in mind that there are numerous factors related to resuscitation and therapeutic intervention that occurred during the first days of care that can condition in-hospital mortality.<a class="elsevierStyleCrossRef" href="#bib0035"><span class="elsevierStyleSup">2</span></a> For all these reasons, an evaluation of prognostic biomarkers seems more appropriate during the first patient care interval, to help in making decisions about risk stratification, treatment and final patient destination. Its greatest utility, from that first intervention, has to do with monitoring the therapeutic response.<a class="elsevierStyleCrossRef" href="#bib0040"><span class="elsevierStyleSup">3</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Secondly, it is known that the elevation of NT-proBNP is higher in patients with reduced systolic function compared to those with preserved function,<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">4</span></a> so it would have been interesting to know their existence or lack of it in the studied patients, as well as to have considered it in the analysis, since it could behave as a confounding factor. This fact is even more important when the present study showed that heart failure was a predictor of biomarker elevation.</p><p id="par0020" class="elsevierStylePara elsevierViewall">Thirdly, it should be assessed whether the fact that 69% of the infectious processes were respiratory could influence the results obtained, and whether the predictive capacity of NT-pro-BNP is maintained in all infection models. In addition, there are other conditions that can modify NT-proBNP, such as age, sex, pulmonary hypertension or kidney failure.<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">4</span></a> Although the first 2 were included as independent variables, it does not appear from the wording of the article that the presence of renal insufficiency or pulmonary hypertension was included, and therefore this could have conditioned the findings described in the article.</p><p id="par0025" class="elsevierStylePara elsevierViewall">Finally, with regard to special populations, and in order to know the behavior of these biomarkers in elderly patients, we would like to provide the results of an analysis on the prospective cohort of the Infections Group of the Spanish Society of Emergency Medicine (INFURG-SEMES) that included infected patients ≥75 years of age from 69 hospitals where NT-proBNP, <span class="elsevierStyleSmallCaps">C</span>-reactive protein, procalcitonin and lactate determinations were available upon arrival at the emergency department.<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">5</span></a> We included 468 patients with a mean age of 84.8 (SD: 5.9) years, of which 239 (51.1%) were male and 204 (43.6%) had a Charlson index ≥3. The main models of infection were respiratory (63.7%) and urinary (22.4%), and 248 (53%) met sepsis criteria. Fifty-six (12%) cases died in the first 30 days.
