Abstract
The effects of prostaglandin E (PGE) combined with continuous renal replacement therapy (CRRT) on renal function and inflammatory responses in patients with septic acute kidney injury (SAKI) remain unclear. To investigate the effects of PGE combined with CRRT on urinary augmenter of liver regeneration (ALR), urinary Na+/H+ exchanger 3 (NHE3), and serum inflammatory cytokines in patients with SAKI. The clinical data of 114 patients with SAKI admitted to Yichang Second People's Hospital from May 2017 to January 2019 were collected. Fifty-three cases treated by CRRT alone were included in a control group, while the other 61 cases treated with PGE combined with CRRT were included in an experimental group. Their urinary ALR, urinary NHE3, serum inflammatory cytokines, renal function indices, and immune function indices were detected. Changes in disease recovery and the incidence of adverse reactions were observed. The 28-d survival curve was plotted. Before treatment, urinary ALR, urinary NHE3, blood urea nitrogen (BUN), serum creatinine (SCr), CD3+ T lymphocytes, CD4+ T lymphocytes, and CD4+/CD8+ T lymphocyte ratio in the control and experimental groups were approximately the same. After treatment, urinary ALR and NHE3 decreased, while BUN, SCr, CD3+ T lymphocytes, CD4+ T lymphocytes, and CD4+/CD8+ T lymphocyte ratio increased in all subjects. Urinary ALR, urinary NHE3, BUN, and SCr in the experimental group were significantly lower than those in the control group, while CD3+ T lymphocytes, CD4+ T lymphocytes, and CD4+/CD8+ T lymphocyte ratio were significantly higher than those in the control group (P < 0.05). After treatment, the levels of tumor necrosis factor-α, interleukin-18, and high sensitivity C-reactive protein in the experimental group were significantly lower than those in the control group (P < 0.05). The time for urine volume recovery and intensive care unit treatment in the experimental group was significantly shorter than that in the control group (P < 0.05), although there was no statistically significant difference in hospital stays between the two groups. The total incidence of adverse reactions did not differ statistically between the two groups. The 28-d survival rate in the experimental group (80.33%) was significantly higher than that in the control group (66.04%). PGE combined with CRRT is clinically effective for treating SAKI, and the combination therapy can significantly improve renal function and reduce inflammatory responses.
