AIM: Studies showed an increased visceral adipose tissue and peritoneal angiogenesis in peritoneal dialysis (PD) patients. However, the relationship between the visceral adipose expands and peritoneal angiogenesis remains unclear.METHODS: Pref-1 (preadipocyte factor-1) recombinant adeno-associated virus (AAV) and control AAV were constructed. Mice were divided into 4 groups, mice in control and PD group were injected intraperitoneally with PBS, mice in control-AAV-PD and pref-1-AAV-PD group were injected with plaque-forming unit (PFU) control AAV and PFU recombinant AAV, respectively. Two weeks later, control group and other groups was injected intraperitoneally with normal saline and 4.25% peritoneal dialysis fluid (PDF) respectively. Visceral adipose tissue was collected and weighed. Pref-1 protein expression and peritoneal permeability as well as mesenteric blood vessel number and vascular endothelial growth factor (VEGF) in serum were measured.RESULTS: Pref-1 protein expression increased in pref-1-AAV-PD group. Visceral adipose expanded in PD and control-AAV-PD group while decreased in pref-1-AAV-PD group, which approves PDF enhance visceral adipogensis, and the process could be inhibited by Pref-1 recombinant AAV. The reduction of peritoneal vessel number and the decrease of vascular permeability as well as down-regulation of serum VEGF observed in pref-1-AAV-PD group suggested peritoneal angiogenesis could be inhibited following visceral adipose tissue reduction.CONCLUSION: Visceral adipose expands is associated with peritoneal angiogenesis in PD treatment, and prevention of visceral adipogenesis may be an alternative way to protect the validity of peritoneum.
