The Charlson index for the population included in our study is around 2. Of these, 43% of patients had hypertension, 33% hypercholesterolaemia and 16% diabetes mellitus. These data are very similar to those of other studies evaluating the presence of comorbidities in COPD patients.<a class="elsevierStyleCrossRefs" href="#bib0105"><span class="elsevierStyleSup">21,22</span></a> This confirms that our sample is a representative population of patients with COPD and their spectrum of the most common comorbidities, since only those that could cause anaemia were excluded.</p><p id="par0125" class="elsevierStylePara elsevierViewall">The anaemia was generally mild (mean haemoglobin values of 11.9<span class="elsevierStyleHsp" style=""></span>±<span class="elsevierStyleHsp" style=""></span>0.95<span class="elsevierStyleHsp" style=""></span>g/dL) and its characteristics were consistent with anaemia of chronic disease, similar to other previous studies.<a class="elsevierStyleCrossRefs" href="#bib0025"><span class="elsevierStyleSup">5,7,9</span></a> Having applied very strict exclusion criteria, our study suggests that the prevalence of anaemia not attributable to other causes in stable COPD patients is lower than found up to now in the literature, and may be close to the prevalence of anaemia in the general population in the same age range.</p><p id="par0130" class="elsevierStylePara elsevierViewall">Although it did not reach statistical significance, patients with anaemia had a tendency to have more severe COPD in terms of FEV<span class="elsevierStyleInf">1</span>, with a prevalence of anaemia in patients with very severe COPD close to 9%.

The efficiency of gas exchange depends on haemoglobin levels; if these fall, that exchange and, therefore, the exercise capacity could worsen.<a class="elsevierStyleCrossRef" href="#bib0115"><span class="elsevierStyleSup">23</span></a> In our study, no differences were observed with respect to the dyspnoea scale, or in metres covered in the 6-minute walk test, unlike two previous studies that analysed these parameters, in which patients with anaemia had a higher grade of dyspnoea and covered less distance in the 6-minute walk test.</p><p id="par0140" class="elsevierStylePara elsevierViewall">Although there is increasing data in relation to the role of systemic inflammation in COPD, few studies mention the physiopathology of COPD-associated anaemia. In theory, this could be similar to other chronic inflammatory diseases, where it has been postulated that its origin could be in an immunological and inflammatory response, mediated by TNF-α, IL-1, IL-6 and interferon gamma, which would generate changes in iron metabolism, reducing its intestinal absorption and altering haematopoiesis.<a class="elsevierStyleCrossRefs" href="#bib0010"><span class="elsevierStyleSup">2,24</span></a> In patients with COPD, there is an increase in these mediators, which could be considered as factors related with the onset of anaemia associated with this disease.<a class="elsevierStyleCrossRef" href="#bib0125"><span class="elsevierStyleSup">25</span></a> In our study, the anaemia presented findings consistent with anaemia of chronic disease, and as in two other previous studies,<a class="elsevierStyleCrossRefs" href="#bib0025"><span class="elsevierStyleSup">5,25</span></a> it presented with low iron and significantly higher erythropoietin levels, which support the theory of peripheral resistance to the action of erythropoietin mediated by an inflammatory component. These findings, which are common to other chronic diseases that present with anaemia, are important, as studies have recently been carried out suggesting that the correction of iron deficiency in patients with heart failure could improve their prognosis, thereby opening new therapeutic targets to be studied in the future.<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">26</span></a></p><p id="par0145" class="elsevierStylePara elsevierViewall">Only one previous paper<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> compared interleukin and CRP values in COPD patients with and without anaemia in relation to healthy controls. In this study, IL-6 and CRP were significantly higher in COPD patients than in controls, with no differences found in the other interleukins (IL-8 and IL-10). In the COPD group, patients with anaemia had significantly higher CRP values than non-anaemic patients, but no differences were found in the IL-6, IL-8 and IL-10 values. In our study, we found a non-significant increase in CRP levels, and patients with anaemia had significantly lower IL-6 values and a direct correlation between the haemoglobin and IL-6 levels. We did not find a physiopathological explanation for these findings, which should be confirmed in future studies.</p><p id="par0150" class="elsevierStylePara elsevierViewall">Moreover, there are other added factors that influence the erythropoietic response and which also may be present in COPD patients.<a class="elsevierStyleCrossRef" href="#bib0135"><span class="elsevierStyleSup">27</span></a> Thus, it is known that certain drugs may influence haemoglobin levels, such as angiotensin-converting-enzyme inhibitors and angiotensin II receptor inhibitors, which cause a decrease in haemoglobin and erythropoietin levels. These drugs are often used for the treatment of hypertension and, according to some studies, the prevalence of this condition in COPD patients could be around 50%.<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">28</span></a> Other treatments, such as theophylline, may also influence erythropoiesis, by a complex mechanism of apoptosis induced by the drug itself.<a class="elsevierStyleCrossRef" href="#bib0145"><span class="elsevierStyleSup">29</span></a> In our study, 50% of patients with anaemia were on treatment with angiotensin II receptor blockers compared to 11.5% of the group without anaemia (<span class="elsevierStyleItalic">P</span>=.03), although no differences were found in relation to the use of other drugs such as angiotensin-converting-enzyme inhibitors and theophyllines.</p><p id="par0155" class="elsevierStylePara elsevierViewall">Our study is not free of limitations, especially those that could be derived from the sample size or the use of some exclusion criteria not included in previous studies, which could limit the comparison of our data with previously published results. Despite this, our data are interesting, as they show a lower prevalence of COPD-associated anaemia than previously described and open the door to physiopathological theories that could explain the onset of anaemia in these patients. Further studies with larger COPD populations and stricter inclusion criteria are required in order to eliminate confounding factors, and which allow a better understanding of the onset of anaemia in these patients from a physiopathological point of view and of the clinical and prognostic implications.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0095">Funding</span><p id="par0160" class="elsevierStylePara elsevierViewall">This study was partially funded by <span class="elsevierStyleGrantSponsor" id="gs0005">GlaxoSmithKline S.A.</span> (<span class="elsevierStyleGrantNumber" refid="gs0005">CRT114268</span>).</p></span><span id="sec0040" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0100">Conflict of Interests</span><p id="par0165" class="elsevierStylePara elsevierViewall">The authors declare that they have no conflict of interests.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:11 [ 0 => array:2 [ "identificador" => "xres272959" "titulo" => array:5 [ 0 => "Abstract" 1 => "Background" 2 => "Methods" 3 => "Results" 4 => "Conclusions" ] ] 1 => array:2 [ "identificador" => "xpalclavsec254944" "titulo" => "Keywords" ] 2 => array:2 [ "identificador" => "xres272960" "titulo" => array:5 [ 0 => "Resumen" 1 => "Introducción" 2 => "Métodos" 3 => "Resultados" 4 => "Conclusiones" ] ] 3 => array:2 [ "identificador" => "xpalclavsec254943" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0010" "titulo" => "Methods" "secciones" => array:2 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Sample Size" ] 1 => array:2 [ "identificador" => "sec0020" "titulo" => "Statistical Analysis" ] ] ] 6 => array:2 [ "identificador" => "sec0025" "titulo" => "Results" ] 7 => array:2 [ "identificador" => "sec0030" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0035" "titulo" => "Funding" ] 9 => array:2 [ "identificador" => "sec0040" "titulo" => "Conflict of Interests" ] 10 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2013-02-02" "fechaAceptado" => "2013-04-30" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec254944" "palabras" => array:5 [ 0 => "Anaemia" 1 => "Chronic obstructive pulmonary disease" 2 => "Prevalence" 3 => "Interleukin" 4 => "Erythropoietin" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec254943" "palabras" => array:5 [ 0 => "Anemia" 1 => "Enfermedad pulmonar obstructiva crónica" 2 => "Prevalencia" 3 => "Interleucinas" 4 => "Eritropoyetina" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:2 [ "titulo" => "Abstract" "resumen" => "<span class="elsevierStyleSectionTitle" id="sect0010">Background</span><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Anaemia is one of the extrapulmonary manifestations of chronic obstructive pulmonary disease (COPD).
