OBJECTIVE: We conducted this study to assess the clinical application of obestatin and arginine vasopressin (AVP) levels in cases of acute renal failure (ARF) and acute heart failure (AHF).
PATIENTS AND METHODS: 30 cases of ARF, 30 cases of AHF, 30 cases of ARF complicated with AHF, and 30 cases of healthy subjects (control group) were successively selected. An ELISA test was conducted to detect levels of obestatin and AVP. Routine biochemistry testing was applied to detect the levels of serum creatinine and calculate the glomerular filtration rate (GFR). Electrochemiluminescence double antibody sandwich fluorescence immune testing was applied to detect NT-proBNP and color Doppler ultrasound diagnostic apparatus was applied to detect renal arterial resistive index (RI) and left ventricular ejection fraction (LVEF). The 30-day mortality was documented.
RESULTS: Compared to other groups, the group of patients suffering from ARF complicated with AHF had significantly higher levels of obestatin and AVP, and significantly higher levels of serum creatinine, NT-proBNP and RI; however, their GFR and LVEF levels were the lowest. Differences were statistically significant (p < 0.05). Levels of obestatin and AVP are positively correlated with serum creatinine, NT-proBNP and RI levels, but negatively correlated with GFR and LVEF levels. The mortality rate of the group suffering from ARF complicated with AHF was markedly increased (p = 0.035). The obestatin and AVP levels of the death group were significantly higher than that of the survival group. However, the comparison among levels of serum creatinine, GFR, NT-proBNP, RI and LVEF revealed no statistical significance (p > 0.05).
CONCLUSIONS: Obestatin and AVP levels were closely related to the severity of ARF and AHF and survival prognosis, which could be a sensitive indicator for diagnoses and prognoses.
