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.

L-arginine and its (patho-)physiologically active derivatives, L-homoarginine and asymmetric dimethylarginine (ADMA), show significant differences in their renal clearance. The underlying molecular mechanisms remain to be elucidated, but selective tubular transport protein-mediated mechanisms likely play a role. In the present study, we investigate the human heteromeric transporter bAT-rBAT (encoded by the SLC7A9 and SLC3A1 genes) as a potential candidate because it is localized in the luminal membrane of human proximal tubule cells and capable of mediating the cellular uptake of amino acids, including L-arginine.

Background And Aims: Previous studies have linked aberrant nitric oxide (NO) metabolism with vascular diseases. Although arginine, homoarginine, asymmetric dimethylarginine (ADMA), and symmetric dimethylarginine (SDMA) are involved in NO metabolic pathways, their associations with ischemic stroke (IS) remain unclear.
Methods And Results: We conducted a case-control study nested within the Prospective Follow-up Study on Cardiovascular Morbidity and Mortality in China (PFS-CMMC) (2013-2018, n = 16,457; median follow-up time: 5.

Background: Optimal balance between macro- and microcirculation in critically ill patients is crucial for ensuring optimal organ perfusion. Nitric oxide (NO) is a regulator of vascular hemostasis and tone. The availability of NO is controlled by asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), and the availability of the NO substrates arginine and homoarginine.

Background: Intrauterine fetal growth restriction (IUGR) affects up to 10% of all pregnancies. Severe IUGR is associated with impaired kidney development, reduced nephron endowment, and chronic kidney disease later in life. Currently, no early predictive biomarker exists for detecting altered kidney function in neonates with IUGR.

Low nasal nitric oxide (nNO) is a typical feature of Primary Ciliary Dyskinesia (PCD). nNO is part of the PCD diagnostic algorithm due to its discriminative power against other lung diseases, such as cystic fibrosis (CF). However, the underlying pathomechanisms are elusive.
