LT has been suggested to be a solution to this disease, but elevation of urinary and blood MMA was still observed after LT. In this study, we measured dry blood spot MMA and its precursor propionyl-carnitine (C3-carnitine) for mut0 patients. The results revealed that when C3-carnitine rose during metabolic stress, MMA rose exponentially (up to 1000 μmol/L) in patients who did not undergo LT. In patients who underwent LT, MMA rose to 100-200 μmol/L when C3-carnitine reached 10-20 μmol/L. However, when C3-carnitine rose further to 40-50 μmol/L, MMA levels just stayed put. Therefore, LT stabilized blood MMA level, though there might be a threshold for blood MMA clearance by the donor liver. This finding should be critical to understand the long-term outcome for LT in methylmalonic acidemia. ? 2009 John Wiley & Sons A/S. |
