Abstract

Chronic airways infection and inflammation are leading causes of morbidity and mortality in chronic lung diseases CLD. Pulmonary exacerbations are major causes of morbidity in CLD. Exhaled carbon monoxide eCO is a product of endogenous metabolic processes whose presence in exhaled breath is considered an index of inflammatory processes. Objective. To evaluate carbon monoxide eCO as inflammatory marker for early detection of acute exacerbation in CLD. Methods. Case control study included 40 children with CLD twenty in exacerbation, group I and twentyin quiescent period, group II recruited from the Chest Clinic, Children’s Hospital, Ain Shams University. Twenty apparently healthy children were included as controls group III. Results. Patients’ mean age was 9.98 ± 3.29 years: 24 60% males and 16 40% females. The mean eCO level among patients during exacerbation was 5.35 ± 1.35 ppm compared to 2.65 ± 0.49 ppm in quiescent stage and 1.30 ± 0.47 ppm in controls. eCO cutoff value discriminating cases and control was 1.5 ppm sensitivity; 100% and specificity 70% and cutoff value discriminating group I from group II was 3 ppm sensitivity: 100% and specificity: 100%. Conclusion. Exhaled CO can be considered a noninvasive early marker of acute exacerbation of CLD.
