title: Evaluation of serum paraoxonase and arylesterase activities in subjects with asthma and chronic obstructive lung disease.
abstract: BACKGROUND
  Asthma and chronic obstructive lung disease (COPD) are characterised by airway inflammation. Paraoxonasel (PON1) and arylesterase (AE) enzymes have the ability to protect HDL from oxidation and may have antiatherogenic, antioxidant, and antiinflammatory features. We carried out a study to assess if there is a difference between PON1 and AE activities and biochemical values between asthmatics and COPD patients and if there is a difference between comorbid or pure COPD patients.
  
  
  METHODS
  40 asthmatics, 20 pure COPD, 20 comorbid COPD patients, and 20 healthy controls were included. We excluded patients with hypertension, metabolic syndrome, diabetes mellitus, thyroid, renal, hepatic, rheumatic, cardiac, cerebrovascular, malignant, and infectious diseases to establish the asthma and pure COPD groups. Patients using drugs which could affect PON1 and AE were excluded in these groups. There were 11 hypertensive, 5 diabetic, and 4 cardiac patients in the comorbid COPD group. PON1 and AE activities were measured spectrophotometrically.
  
  
  RESULTS
  Mean age was higher and male gender was more prevalant in COPD than other groups. Fasting blood glucose, LDL-cholesterol, triglyceride, leucocyte counts, erythrocyte sedimentation rate, and hs-CRP levels were higher in COPD patients. Although PON1 and AE were lower in patients than controls, no difference was found between the asthma and COPD groups, nor between pure and comorbid COPD patients.
  
  
  CONCLUSIONS
  Although asthma and COPD are two different conditions PON1 and AE activities cannot be markers of differantial diagnosis as they overlap. Comorbid COPD patients may have similar enzyme levels because of the drugs such as statins and aspirin.
