Her blood tests and chest X-ray scan showed the presence of anemia (7.5 g/dL), of an inflammatory syndrome (erythrocyte sedimentation ratio [ESR] – 100 mm/h, C-reactive protein [CRP] – 170 mg/dL), and of radiologic alterations suggestive for interstitial pneumonia and bilateral pleural effusion. Here, CRP is linked to anemia (phenotype).
