HGF and peritonitis: However, patients with peritonitis had significantly more increase in PD effluent HGF level from baseline to one year than those without peritonitis (390.3 ± 1121.4 vs −54.6 ± 305.9 pg/ml, p = 0.024), and the number of peritonitis episode during follow up period had a modest but statistically significant correlation with the change in PD effluent HGF level over one year (r = −0.303, p = 0.041).
