It has been reported that small airway inflammation is closely associated with the severity of airflow limitation in COPD (chronic obstructive pulmonary disease). We tested a new method of measurement of biochemical constituents in ELF (epithelial lining fluid) obtained separately from the central or peripheral airways using a bronchoscopic microsampling technique. The present study was designed to determine the validity of measuring CML [N(epsilon)-(carboxymethyl)lysine] levels in ELF for the assessment of small airway inflammation in COPD. Ten non-smokers, ten current smokers and 16 COPD patients were included in the present study. Concentrations of CML, 8-isoprostane and IL-8 (interleukin-8) were measured in ELF separately from the central or peripheral airways. CML levels in central airways did not differ significantly, but were markedly higher in peripheral than in central airways in the three groups. However, CML levels in peripheral airways of COPD patients were significantly higher than those in non-smokers and current smokers. In COPD patients, the CML level in peripheral airways was significantly correlated with FEV1 (forced expiratory volume in 1 s) (r=-0.82, P=0.002) and FEV1/FVC (forced vital capacity) (r=-0.57, P=0.03). Moreover, CML levels in peripheral airways were significantly correlated with levels of both 8-isoprostane (r=0.76, P=0.003) and IL-8 (r=0.67, P=0.01). In conclusion, these findings suggest that elevated levels of CML in ELF from peripheral airways were observed in COPD patients, and this parameter was correlated with the severity of airflow limitation.

An 82-year-old male with a history of high blood pressure, COPD, chronic myeloid leukemia, and stage-4 chronic renal failure. Admitted to hospital for lower-limb cellulitis and severe COPD exacerbation, he received antibiotic therapy and bronchodilators. During his hospital stay he developed severe anemia and had an hematochezia event with no diarrhea. A complete colonoscopy found small (4-7 mm) nacreous elevated lesions, circumferential in shape, in the cecum and ascending colon with some bleeding stigmata and submucosal bleeding suggestive of infectious colitis; stool culture was negative and Clostridium difficile toxins were positive. The condition was histologically confirmed.
