Abstract
Acute kidney injury (AKI) is a common complication of bites by Viperidae snakes. The main venomous snakes in South Korea are members of the Viperidae family, but there is limited information on snake-bite induced AKI in South Korea. Therefore, we investigated snake envenomation-related AKI and the performance of surrogate baseline creatinine to diagnose true AKI. This retrospective, case-control study divided 71 patients with baseline serum creatinine into two groups according to the development of envenomation-related AKI determined based on Kidney Disease Improving Global Outcome Classification. The incidence of AKI was 14.1% with 10% having stage-3 AKI. During hospitalization, the AKI group did not develop venom-induced consumption coagulopathy more frequently than did the non-AKI group. Only one patient needed renal replacement therapy, and no patients died. The serum creatinine concentration at presentation underestimated the incidence of AKI, while the lowest creatinine concentration during hospitalization overestimated the incidence of AKI. After discharge, the incidence of chronic kidney disease did not increase in the AKI group. Snake envenomation-related AKI is characterized by a relatively lower incidence and severity, has no correlation with coagulation disturbance, and has favorable short- and long-term outcomes in South Korea. Based on this study, it is recommended that future envenomation-related AKI studies would utilize the baseline creatinine for diagnosing AKI. If not, envenomation-related AKI studies should include the definition of baseline creatinine used to diagnose AKI and report bias if a baseline creatinine surrogate is used.

Moon JM, Chun BJ, Koo YJ. The association between the neutrophil lymphocyte ratio and local edema after viper snake envenomation in South Korea. Toxicon 2024; 240:107635. [PMID: 38364981 DOI: 10.1016/j.toxicon.2024.107635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 01/30/2024] [Accepted: 01/30/2024] [Indexed: 02/18/2024]
Abstract
The role of the inflammatory process in the pathogenesis of local edema-related envenomation has not been explored with endemic venomous snakebites in Korea. Gloydius species are responsible for most snakebites in South Korea. In this study we aimed to investigate whether the neutrophil-lymphocyte ratio is relevant to snake envenomation-induced local edema in South Korea. This retrospective study divided 126 patients into two groups according to local edema severity at presentation. Logistic regression models were used to investigate the association between the neutrophil-lymphocyte ratio and local edema. Sixty-one (48.4%) patients had grade 2 or higher local edema at presentation despite 21 of them being given antivenom before presentation. During hospitalization, local edema progressed in 61 patients 48 (11.5-48) hours after presentation, and 54 patients demonstrated grade 3 or higher local edema. A higher neutrophil-lymphocyte ratio at presentation after adjustment for factors related to envenomation and antivenom administration and factors influencing the neutrophil-lymphocyte ratio were associated with both a higher grade of local edema at presentation and a higher peak local edema grade during hospitalization. The delta neutrophil-lymphocyte ratio during the first 24 h after presentation was related to the local edema progression after presentation. The neutrophil-lymphocyte ratio at presentation is associated with the severity of local edema-related envenomation. Furthermore, the change in the neutrophil-lymphocyte ratio during the first 24 h is related to the risk of local edema progression. Further clinical and experimental research aimed at investigating the role of inflammation on the pathogenesis of local edema should be conducted. This study may suggest the introduction of short-term anti-inflammatory agents considering the failure of antivenom to curb local edema.

Abstract
INTRODUCTION Three venomous snakes of the Gloydius genus belonging to the Viperidae family cause most snake envenomations in South Korea. Envenomation signs often include local swelling, coagulopathy, and rhabdomyolysis. The benefit of additional antivenom after the initial does is unclear. METHODS This retrospective study divided patients into four groups according to the presence of rhabdomyolysis (creatine kinase ≥1000 IU/L) and coagulopathy, which were defined using the Korean Society on Thrombosis and Hemostasis disseminated intravascular coagulation score (rhabdomyolysis, coagulopathy, combination, and local effects groups). We describe the clinical features of envenomation and the antivenom response. RESULTS Greater local swelling predicted more severe snakebite pain. Ninety of the 231 enrolled patients (38.9%) developed rhabdomyolysis. The patients with severe rhabdomyolysis in the combination group displayed higher peak creatine kinase activity than the rhabdomyolysis group. Seven patients with rhabdomyolysis, including two patients requiring kidney replacement therapy, developed acute kidney injury, but the incidence of acute kidney injury did not differ between the combination group and rhabdomyolysis group. Bleeding developed in 3.5% of the patients, but its incidence did not differ between the combination and coagulopathy groups. Approximately half of all patients needed repeated antivenom administration, mainly due to the local envenomation effect. Earlier administration of additional antivenom for progressive local swelling did not reduce the hospitalization duration. CONCLUSION Rhabdomyolysis is one of the major effects of Gloydius snake envenomation in South Korea, although it is not associated with the same risk of clinical deterioration as coagulopathy. Additionally, the ability of antivenom to ameliorate local swelling should be investigated to prevent unnecessary antivenom administration in South Korea.

The Usefulness of Platelet Distribution Width and Platelet Distribution Width to Lymphocyte Ratio in Predicting Severity and Outcomes in Patients with Snakebite. Wilderness Environ Med 2021; 32:284-292. [PMID: 34172373 DOI: 10.1016/j.wem.2021.03.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 03/18/2021] [Accepted: 03/19/2021] [Indexed: 01/17/2023]
Abstract
INTRODUCTION Tissue damage, inflammatory response, and hematologic abnormalities may occur in snakebite envenomation. This study aimed to evaluate the predictive ability of platelet distribution width (PDW) and platelet distribution width to lymphocyte ratio (PDWLR) in the severity and outcome of envenomation in patients with snakebites in the emergency department (ED). METHODS All adult patients admitted to the ED after a snakebite were retrospectively evaluated. Patients were classified according to the severity of envenomation. The relationship between the PDW and PDWLR and envenomation severity and patient outcomes was analyzed. Multivariate logistic regression analysis was performed to determine the predictors of severe envenomation. Results were presented as 95% CIs with odds ratios. Statistical significance was accepted at P<0.05. RESULTS Envenomation was classified as none/minimal in 42 patients and moderate/severe in 29. PDW and PDWLR were significantly higher in the moderate/severe group (P=0.016 and P<0.001, respectively). Cut-off values of 16.5 for PDW and 6.15 for PDWLR were related to more severe envenomation (area under the curve 0.67, 95% CI 0.55-0.78 and area under the curve 0.85, 95% CI: 0.74-0.92, respectively). Blood product replacement, thrombocytopenia, hematologic abnormality, advanced local findings, compartment syndrome/fasciotomy, antivenom dosing, and moderate/severe envenomation were associated with PDWLR >6.15 (P<0.05). In multivariate analysis, PDWLR (odds ratio 1.19 [95% CI 1-1.4]; P=0.04) was an independent predictor of severe envenomation. CONCLUSIONS Higher PDW and PDWLR were associated with severe envenomation in patients with snakebites in the ED. PDWLR may be used as a predictor of severe envenomation and adverse outcomes.

Snakebite envenomings in the Republic of Korea from the 1970s to the 2020s: A review. Toxicon 2021; 196:8-18. [PMID: 33781797 DOI: 10.1016/j.toxicon.2021.03.013] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 02/22/2021] [Accepted: 03/22/2021] [Indexed: 11/23/2022]
Abstract
Snakebite envenomings remain a neglected disease across the globe causing severe injuries and death. An understanding of regional snakebite patterns is a necessary prerequisite for public health programs aimed at reducing snakebite risks. However, such regional knowledge is poorly documented or lacking in many countries where the risk of snakebite envenomings receive little medical attention, and the Republic of Korea is one of these countries. Here, we reviewed the literature on snakebites published between 1970 and 2020 as well as public healthcare data recorded between 2010 and 2019 to determine the patterns of snakebite envenomings in the Republic of Korea. Our results, based on literature data, show Gangwon province as a hotspot of snakebite occurrences and identify middle-aged males living in rural areas as the demographic group at highest risk of venomous snakebites. We also highlight major limitations for further understanding snakebite patterns in the country, most notably the lack of proper species identification for snakes and conflicting patterns of envenomings revealed by different sources of data. Our study provides baseline information on venomous snakebites occurring in the Republic of Korea, thereby filling a gap in the knowledge of snakebite trends in the country.

Abstract
OBJECTIVE This retrospective study investigated the nature and severity of venom-induced consumption coagulopathy (VICC) and determined the clotting factors involved in VICC in patients after envenomation by South Korea's snakes. Additionally, we studied the effectiveness of antivenom for the treatment of VICC after envenomation. METHODS Included patients were divided into three groups according to the severity of VICC (no VICC, partial VICC, and complete VICC). Data, including changes in coagulation parameters during hospitalization and clotting factors at presentation, were collected and analyzed. RESULTS One hundred nineteen patients who presented at our emergency department within 3 h after snake envenomation were included. VICC developed in 34 patients (27 patients with partial VICC and 7 patients with complete VICC). Two of 34 patients with VICC required blood transfusions. Five patients with complete VICC had an undetectable fibrinogen concentration at presentation. Three patients with complete VICC had an unmeasurable INR and aPTT within 24 h. The median times of the most extreme values were 10 h for INR, 12 h for aPTT, and 16 h for fibrinogen after presentation in the VICC group. The D-dimer concentration peaked at a median of 63.5 h after presentation. The activities of factors II and X were significantly reduced in the complete VICC group (factor II: 88 (84-99.3)% in the non-VICC group vs. 69 (49.5-83.5)% in the complete VICC group; factor X:94 (83-102) in the non-VICC group vs. 70 (66.5-79.8)% in the complete VICC group), while there was no difference in factor V activity at presentation. The time from bite to first antivenom administration did not correlate with the time course and most extreme concentrations for fibrinogen and D-dimer within the VICC groups. DISCUSSION AND CONCLUSION VICC occurs in approximately one-quarter of snakebite patients in South Korea; however, VICC itself does not appear to lead to clinical deterioration. Fibrinogen is an early diagnostic maker for complete VICC. Clotting factors II and X are involved in VICC. Future investigations should explore the mechanism of VICC from Korean snakebites and the effect of antivenom on VICC.

Abstract
CONTENT This study investigated the incidence, progression and clinical course of myocardial injury-related snake envenomation in South Korea. In addition, this study evaluated whether antivenom guidelines are appropriate to control envenomation in patients with myocardial injury. METHODS The study included 198 patients who received antivenom after a snakebite, and they were divided into two groups according to evidence of myocardial injury (defined as elevated troponin I or ischemic change on electrocardiogram) at presentation. Data including serial troponin I, echocardiogram/coronary angiogram findings, the clinical course, and treatment were collected and analyzed. RESULTS The incidence of myocardial injury at presentation was 15.2%. The troponin I level was 0.11 (0.07-0.56) ng/ml at presentation and tended to decrease over 24 h. Echocardiograms revealed neither regional wall motion abnormalities nor left ventricular dysfunction in 15 of 17 patients, while two patients showed signs of coronary artery stenosis on echocardiograms and coronary angiograms. However, compared with patients without myocardial injury, patients with myocardial injury had a higher frequency of systemic envenomation complications, including bleeding, respiratory failure, hypotension, acute kidney injury, thrombocytopenia and venom-induced consumption coagulopathy (VICC). The patients with myocardial injury at presentation needed significantly more frequent and larger doses of antivenom than indicated by the initial severity of envenomation. Multivariate analysis showed that myocardial injury was associated with the need for additional antivenom administration after initial administration. DISCUSSION AND CONCLUSION Myocardial injury is not uncommon after snake envenomation in Korea. Although myocardial injury itself seems to be benign, the clinical course of patients with myocardial injury is complicated, and myocardial injury is associated with the need for additional antivenom administration. The optimal use of antivenom to control envenomation in patents with myocardial injury after snake envenomation in South Korea should be established.

Abstract
Pit viper venom commonly causes venom-induced consumptive coagulopathy (VICC), which can be complicated by life-threatening hemorrhage. VICC has a complex pathophysiology affecting multiple steps of the coagulation pathway. Early detection of VICC is challenging because conventional blood tests such as prothrombin time (PT) and activated partial thromboplastin time (aPTT) are unreliable for early-stage monitoring of VICC progress. As the effects on the coagulation cascade may differ, even in the same species, the traditional coagulation pathways cannot fully explain the mechanisms involved in VICC or may be too slow to have any clinical utility. Antivenom should be promptly administered to neutralize the lethal toxins, although its efficacy remains controversial. Transfusion, including fresh frozen plasma, cryoprecipitate, and specific clotting factors, has also been performed in patients with bleeding. The effectiveness of viscoelastic monitoring in the treatment of VICC remains poorly understood. The development of VICC can be clarified using thromboelastography (TEG), which shows the procoagulant and anticoagulant effects of snake venom. Therefore, we believe that TEG may be able to be used to guide hemostatic resuscitation in victims of VICC. Here, we aim to discuss the advantages of TEG by comparing it with traditional coagulation tests and propose potential treatment options for VICC.

Abstract
BACKGROUND Predicting severe acute cholecystitis (SAC) is important because the mortality rate is higher for patients with SAC than for non-SAC (NSAC) patients. We evaluated the predictive value of the delta neutrophil index (DNI), which is greater in patients with infectious and inflammatory conditions, for SAC among patients in the emergency department (ED). METHODS This retrospective observational study included 379 consecutive adult patients with AC admitted to the ED from January 2015 to December 2016. The included patients were classified into 2 groups (NSAC and SAC) according to the Tokyo Guidelines 2018. White blood cell (WBC) count, C-reactive protein (CRP) levels, and DNI values were assessed at ED admission. RESULTS The SAC group contained 28 patients (7.4%). DNI was among the early predictors of SAC and was an inflammatory marker with a significantly higher predictive value than WBC count or CRP level for detecting SAC. The predictive power of DNI was significantly higher than that of CRP when used in conjunction with WBC count, abdominal computed tomography, and clinical variables. CONCLUSIONS DNI measured at ED admission may serve as an early predictor of SAC.
