“…Interestingly, risk factors were different depending on the kind of complication (Table 4). For biochemical impairment as reflected by abnormal liver biochemistries, we confirmed some risk factors previously described, such as a young age of TPN initiation, a long duration of TPN, a higher rate of catheterrelated infections, a higher volume and energy content of TPN, and a high glucose rate in TPN (expressed as absolute intake g/kg/d or as in relative amount of % caloric intake) (Candusso et al, 1995;Puntis, 1995;Beath et al, 1996;Kelly, 1998;Quiros-Tejeira et al, 2004;Kumpf, 2006). Surprisingly, the lipid rate in TPN was not statistically significantly related to biochemical abnormalities as previously described (Cavicchi et al, 2000;Kaufman et al, 2003;Kumpf, 2006;Diamanti et al, 2007;Hermans et al, 2007).…”
