A clinical study of sepsis patients with hypophosphatemia infected by different bacteria

Abstract

Objective The aim of this study was to compare hypophosphatemia between the sepsis patients and the non-sepsis patients,and between within the subgroups of sepsis patients.Methods We collected 312 sepsis cases and 300 non-sepsis cases by stratified random sampling method yearly.In the sepsis cases,the number infected by gram-negative bacteria was 170,and by gram-positive bacteria was 142,containing 4 different bacteria infected cases in each one.Serum phosphorus of cases in each group were collected.The data were statistically processed to compare the incidence rates of hypophosphatemia,mean serum phosphorus levels and relative risk among groups.Results There was a statistical difference between the sepsis cases and the non-sepsis cases in incidence rate of hypophosphatemia (P ＜ 0.05,and RR ＞ 1.2).There were statistical differences between the cases infected by gram-negative bacteria and the cases infected by the gram-positive bacteria,also among cases infected by 4 different gram-positive bacteria in both incidence rate of hypophosphatemia and average serum phosphorus level (all P ＜ 0.05),and both RR ＞ 1.2.There were no statistical differences among cases infected by 4 different gram-negative bacteria in both incidence rate of hypophosphatemia and average serum phosphorus level (both P ＞ 0.05),and RR ＜ 1.2.Conclusions The sepsis patients were susceptible to hypophosphatemia,especially the ones infected by the 4 gram-negative bacteria,staphylococcus aureus and enterococcus in this study.We should pay attention to the serum phosphorus level seriously and prevent the occurrence of serious complications.
