ABSTRACT
OBJECTIVES: To investigate homoarginine and asymmetric dimethylarginine (ADMA) in controls compared to children with type 1 diabetes (T1D) and if homoarginine and ADMA are affected by atorvastatin. METHODS: Homoarginine and ADMA levels of 28 T1D patients were compared to levels of 41 controls. In T1D patients, homoarginine and ADMA were determined at baseline, 1 year, and 2 years at daily 10 mg atorvastatin or placebo within a double-blind study. RESULTS: At baseline, both homoarginine and ADMA were lower (p<0.001) in T1D patients compared to controls. In T1D patients, homoarginine and ADMA were not influenced by atorvastatin. Inverse correlations between homoarginine and HbA1c (p<0.001) and between ADMA and systolic blood pressure (p=0.005) and pulse pressure (p=0.003) were shown. CONCLUSIONS: Homoarginine and ADMA levels are decreased and associated with cardiovascular risk factors in children with T1D without being affected by atorvastatin.
