Abstract

Background/aim: This study mainly aimed to explore the therapeutic effects of 3 renal replacement therapy (RRT) modalities on acute kidney injury (AKI) caused by wasp stings.

Methods: A retrospective study from September 2016 to December 2019 was conducted. Thirty-one patients with AKIs caused by wasp sting were selected and divided into 3 groups according to the initial RRT modality received, namely, (1) the intermittent hemodialysis combined with hemoperfusion (IHD + HP) group, (2) the continuous veno-venous hemodiafiltration (CVVHDF) group, and (3) the CVVHDF combined with HP (CVVHDF + HP) group. The laboratory results were measured and analyzed before treatment on the 3rd, 7th, and 14th days of treatment. The renal function outcomes and survival of the patients were investigated at 3 months follow-up.

Results: The laboratory results of enzyme measures and inflammatory indicators in wasp sting patients increased significantly in the early stage and 3 RRT modalities were effective in reducing these indicators. In addition, continuous RRT modality (CVVHDF and CVVHDF + HP) showed better clearance of myoglobin than IHD + HP. The serum creatinine levels of patients in the 3 groups did not recover to baseline within 14 days after beginning treatment. Nevertheless, the CVVHDF + HP group was better than the CVVHDF group, and CVVHDF was better than the IHD + HP group on the 3rd day. The interleukin (IL)-6 and IL-10 levels in CVVHDF + HP and IHD + HP groups were obviously lower than those in the CVVHDF group on the 3rd day. In the follow-up study, the recovery rate of renal function in CVVHDF and CVVHDF + HP groups was significantly better than that in the IHD + HP group.

Conclusion: Early RRT was effective in the treatment of patients with A KI caused by wasp sting. CVVHDF + HP and CVVHDF modalities were better than the IHD + HP group in venom clearance and renal function recovery.
