Lipid peroxidation in bronchial asthma.

ABSTRACT

OBJECTIVE: To study the levels of free oxygen redicals in children with bronchial asthma during an attack and symptom free interval. METHODS: Serum Malondiadehyde (MDA) levels were studied in 25 children between the age of 6 years-14 years who presented with an acute attack of bronchial asthma. In each patient, serum MDA levels were measured at the time of admission, 24-48 hours after good response to treatment and after a symptom free interval of 3 weeks. Results were compared with control group. RESULTS: In study group serum MDA levels were highest at the time of admission, which decreased significantly at 24-48 hours with treatment. After a 3 weeks symptom free interval serum MDA levels had decreased further but were still higher than healthy control group. CONCLUSION: Lipid peroxidation is increased in bronchial asthma during an acute attack and symptom free period.
