Are c2 ( 2-h ) levels superior to trough levels as estimates of the area under the curve in tacrolimus-treated renal-transplant patients?
Two-hour levels are not superior to trough levels in tacrolimus-treated renal transplant patients. Despite good correlation between trough level and AUC, some patients may still receive nephrotoxic doses despite trough levels in the desired range. Sampling 3-6 h after oral intake may be at least as good as trough levels.
High CM-specific IgE levels predict the persistence of CMA. Development of tolerance is associated with elevated levels of beta-lactoglobulin-specific serum IgA at the time of diagnosis, and later increasing specific IgG4 levels to beta-lactoglobulin and alpha-casein.
