BACKGROUND: Nephrogenic systemic fibrosis may be caused by gadolinium (Gd)-containing magnetic resonance imaging contrast agents. Most reported cases were associated with one particular agent, gadodiamide. Yet, unidentified cofactors might explain why only a minority of renal failure patients exposed to gadodiamide develop nephrogenic systemic fibrosis. METHODS: We conducted a case-control ...

Methionine synthase reductase (MTRR) and betaine-homocysteine S-methyltransferase (BHMT) are two enzymes that regulate homocysteine metabolism. Elevated homocysteine (hyperhomocysteinemia) is associated with adverse pregnancy outcomes and vascular disease. We assessed whether polymorphisms in MTRR (66A-->G; I22M) and BHMT (742G-->A; R239Q) were associated with abruption. We further evaluated whether homocysteine levels differed ...
