Changes of miR-155 expression in serum of uremic patients before and after treatment and risk factors analysis

The aim of the present study was to investigate the changes of miR-155 expression in the serum of uremic patients before and after treatment and analyze the risk factors of efficacy. A total of 116 uremic patients admitted to the People's Hospital of Chengyang (Qingdao, China) were enrolled in the study as the uremia group, and were treated by hemodialysis combined with hemoperfusion, and 127 healthy subjects who underwent health examination during the same period were selected as the normal group. Reverse transcription quantitative PCR was used to detect the serum miR-155 levels of all the subjects in the two groups before treatment and those of uremia patients after treatment. The changes of clinically related indicators and inflammatory factors in uremic patients before and after treatment and their correlation with miR-155 were investigated. The risk factors affecting the efficacy of treatment were analyzed. Serum miR-155 levels in the uremia group were higher than those in the normal group (P<0.001); the miR-155 level in patients after treatment was significantly lower than that before treatment (P<0.001), and it was positively correlated with efficacy (r=0.6873, P<0.05). The serum miR-155 level in the invalid group was higher than that in the effective group, and the sensitivity and specificity of miR-155 for predicting the efficacy before treatment were 64.71 and 87.88%, respectively. After treatment, the sensitivity and specificity of miR-155 for evaluating the efficacy were 76.47 and 88.89%, respectively. Clinically related indicators and inflammatory factor levels in uremic patients decreased significantly after treatment, and the expression levels before and after treatment were significantly correlated with miR-155. Clinically related indicators, inflammatory factors and miR-155 were all risk factors affecting efficacy. The expression level of miR-155 in serum was significantly upregulated. Findings of this study suggest that monitoring miR-155 may reflect the efficacy and inflammatory state effectively.

Effects of hemodialysis combined with hemoperfusion on severe acute pancreatitis

BACKGROUND/AIMS

Severe acute pancreatitis (SAP) is characterized by persistent organ failure. This research aimed to evaluate the effect of hemodialysis combined with hemoperfusion on SAP.

MATERIALS AND METHODS

Thirty-seven patients who were treated with hemoperfusion combined with hemodialysis were included in group O, and 31 patients treated with conventional therapy and hemoperfusion were included as control (group C). Leukocyte count, neutrophil percentage, amylase (AMY), blood urine nitrogen (BUN), creatinine (Cr), and total bilirubin (TBIL) were noted. The time when symptoms disappeared as well as complications after treatment was recorded.

RESULTS

Leukocyte count, neutrophil percentage, AMY, BUN, Cr, and TBIL in two groups were remarkably decreased after treatment. However, these indexes were significantly lower in group O than those in group C after treatment, especially the neutrophil percentage, AMY, BUN, Cr, and TBIL. The time when the symptoms disappeared was 3.01±1.02 days in group O, which was shorter than 5.56±1.88 days in group C. There were 4 patients with acute renal failure and 2 patients had multiple organ failure in group C after treatment. But only 1 patient developed acute renal failure in group O. The difference in complications between two groups was significant (p<0.024).

CONCLUSION

The combination of hemodialysis and hemoperfusion could have a better effect on SAP in removing toxic metabolites and inflammation mediators. It not only shortens the time of symptoms disappearing but also decreases the incidence of complications and the mortality.
