Treatment response and clinical features of snakebite envenomation in Alborz province, Iran: A cross-sectional study.

Snakebite envenomation is a significant yet neglected public health burden. Our aim was to investigate the clinical and demographic factors of snakebite envenomation, as well as the factors associated with its severity and response to treatment, in Alborz province, northern Iran. In this cross-sectional study, we included 50 patients diagnosed with snakebite envenomation, referring to the Poison Control Centre of Alborz University of Medical Sciences. The presenting signs and symptoms, demographic data, treatment dose, response to treatment, complications, laboratory findings, and snakebite severity scale (SSS) were collected. Forty-six patients (92%) were men, the total mean age was 31.7 ± 12.06 years, and mean SSS was 6.54 ± 3.39. The patients were admitted for a median of 2 days, and 11 patients needed ICU admissions. The majority of snakebites were in upper extremities (60%) and they mainly occurred in summer (56%). SSS was significantly associated with response to treatment, ICU admission, gastrointestinal adverse events, thrombocytopenia, and length of stay. Similarly, response to treatment was significantly related to the history of snakebite, ICU admission, gastrointestinal adverse events, thrombocytopenia, length of stay, and SSS. Gastrointestinal symptoms, higher severity scores, and longer hospital stays were associated with poor treatment response. Importantly, no mortality was observed in this cohort. Further research is needed to confirm these findings and optimize treatment strategies for snakebite management.

Snakebite incidence and healthcare-seeking behaviors in Eastern Province, Rwanda: A cross-sectional study.

Snakebite envenoming (SBE) is a potentially life-threatening event that can lead to severe physical, mental, and economic hardships, particularly in under-resourced regions like sub-Saharan Africa. In Rwanda, there have been no epidemiological assessments of SBE to guide the Ministry of Health in its efforts to reduce the burden. This study had two main objectives: first, to estimate the incidence of snakebites across districts, and second, to describe formal versus informal healthcare seeking behaviors among snakebite victims in Eastern Province, Rwanda in 2020. This cross-sectional study utilized a cluster sampling approach, involving Community Health Workers (CHWs) who recorded snakebite cases across seven districts. The descriptive analysis considered sampling weights, and healthcare seeking behavior was assessed based on the type of care sought as the first point of treatment. The study surveyed 390,546 individuals across 763 villages and estimated a provincial annual incidence rate of 4.3 cases per 1,000 individuals. Incidence estimates ranged from 1.1 cases per 1,000 in Nyagatare to 9.1 cases per 1,000 individuals in Bugesera and Ngoma districts. Among the 2,545 cases recorded by CHWs, three resulted in deaths. Regarding healthcare-seeking behavior, 13% of snakebite victims (143 out of 1,098) initially consulted formal care providers (CHWs, health post/center, or hospital), while 87% sought informal care (family/friends, pharmacist, or traditional healer). Approximately half of the victims (583, 53.1%) reported severe symptoms. Unsafe practices included skin cutting/burning, tourniquet application, use of black stones, and venom extraction; only 24 cases (2.2%) received anti-venom. This large-scale community-based assessment highlights variations in snakebite incidence between districts and confirms frequent involvement of traditional healers in management. Improving access to anti-venom and community education on the risks of ineffective practices, along with timely use of formal healthcare, are crucial. Collaboration between healthcare providers, traditional healers, community leaders, and policymakers is essential to implement targeted interventions for enhancing snakebite prevention and management strategies.

Knowledge, Attitude, and Practices Toward Snakes and Snakebites among Non-Medical College Students in Cebu, Philippines: A Mixed Method Approach

Understanding community perceptions and behaviors toward snakes is crucial for effective prevention and management in regions where snakebites are a public health concern. Non-medical college students, a significant demographic, can influence broader community health practices and awareness. This study aims to assess the knowledge, attitudes, and practices (KAP) towards snakes and snakebites among non-medical college students in a technological university in the fifth district of Cebu, Philippines. Employing a convergent parallel research design, quantitative data were collected through structured questionnaires, while qualitative insights were obtained via semi-structured interviews. The sample included 546 non-medical college students selected through random sampling. The findings revealed significant gaps and misconceptions, with students exhibiting moderate knowledge about snakes and snakebites. Attitudes were predominantly negative, characterized by fear and aversion. Practices concerning snakebite management needed to be revised, with many students relying on traditional rather than evidence-based methods. The study highlights considerable areas for improvement in the knowledge and practices of non-medical students regarding snakebite management, coupled with generally negative attitudes toward snakes. The novelty of this research lies in its focus on non-medical college students and specific demographics within a technological university, providing insights that can inform targeted educational interventions. Implementing educational programs to improve KAP among students is recommended, emphasizing correct snakebite first aid and fostering a more informed and balanced view of snakes. This research has significant implications for public health, suggesting that targeted education can enhance community health practices and awareness regarding snakebite prevention and management.

Hemocoagulation Conditions Associated with Venom-Induced Consumption Coagulopathy due to Snakebite in Humans

Highlights:1. This review comprehensively highlighted aspects of hematologic abnormalities in snakebites, a topic that remains understudied globally.2. This review contributes insights into the field of snakebite research and improves the management of snakebites by examining the diverse effects of different types of snakebites on hemocoagulation status. Abstract Snakebite remains an underreported health hazard worldwide. The most common effects of snakebite envenomation globally are hematological disorders, with venom-induced consumption coagulopathy (VICC) being the most prevalent and significant condition. This review aimed to explore the hematological aspects of snakebite, with a focus on snakebite-induced consumption coagulopathy. We conducted a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines through a search across several databases, namely PubMed, ScienceDirect, and Google Scholar. The inclusion criteria for this review were studies on snakebite envenomation in humans with a discussion of relevant cases. Additionally, the included studies were conducted between 2010 and 2023 and published in the English language. Studies on animal models were excluded. We used the keywords “venom-induced consumption coagulopathy AND snake" in the search. The critical appraisal was performed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Case Reports and the Mixed Methods Appraisal Tool (MMAT). The findings were presented as a qualitative synthesis of 14 articles covering 316 patients and various snakebite types. The studies on snakebite came from various countries, but mostly from Sri Lanka. The snake types exhibited variation, with certain species existing only in specific areas. The subjects fell into different age groups, from children to the elderly. The majority of the subjects were male. The subjects' youngest age was 6 years old, while the oldest was 70 years old. Prothrombin time (PT) and activated partial thromboplastin time (APTT) were the most discussed variables. Some of the studies demonstrated an increase in PT and APTT, although other studies reported contrasting findings. In conclusion, certain types of snakebite have a different impact on the hemocoagulation status.

A Guide to the Clinical Management of Vipera Snakebite in Italy.

The genus Vipera encompasses most species of medically significant venomous snakes of Europe, with Italy harbouring four of them. Envenomation by European vipers can result in severe consequences, but underreporting and the absence of standardised clinical protocols hinder effective snakebite management. This study provides an updated, detailed set of guidelines for the management and treatment of Vipera snakebite tailored for Italian clinicians. It includes taxonomic keys for snake identification, insights into viper venom composition, and recommendations for clinical management. Emphasis is placed on quick and reliable identification of medically relevant snake species, along with appropriate first aid measures. Criteria for antivenom administration are outlined, as well as indications on managing potential side effects. While the protocol is specific to Italy, its methodology can potentially be adapted for other European countries, depending on local resources. The promotion of comprehensive data collection and collaboration among Poison Control Centres is advocated to optimise envenomation management protocols and improve the reporting of epidemiological data concerning snakebite at the country level.

Combining species distribution models and big datasets may provide finer assessments of snakebite impacts.

Snakebite is a major poverty-related neglected tropical disease. An integrated scientific approach is needed to understand the dynamics of this important health issue. Our objective was to estimate snakebite occurrence in a tropical area by using a blend of ecological modelling and robust statistical analysis. The present study used climatic, environmental, and human population density data to determine the area with snakebite occurrence-probability for the first time in Bangladesh. We also analysed a large, 16-year dataset of hospitalized snakebite cases to reveal the epidemiology of snakebite in the south-eastern zone of the country. Our results show that cobra bite is the most commonly occurring venomous snakebite in humans (around ~12% of the total yearly snakebite records), and men are more frequently bitten than women (2/3 of human victims are men). Most bites occur during the rainy season for cobra and green pit viper, while krait bites are not restricted to any particular season. As snakebite incidents are closely related to climate conditions, we can model snakebite risk using temperature and precipitation variables. Whereas there is a lack of snakebite reports from several parts of the study area in official records, our models predict that the entire study area is favourable for snakebite incidents. Based on the combined evidence we estimate that about 200,000 snakebite events occur every year in the south-eastern part of Bangladesh alone. Considering future global climate change, our model projections show that snakebite incidence in Bangladesh might not significantly decrease in the future (- 2070-); however, the distribution of probabilities might change, with a predicted increase of snakebite incidence in the hilly areas of the country. Using climatic data to predict snakebite incidence in Bangladesh allowed us to provide estimations of the total annual number of snakebite cases in the study area. As in most countries, the scarcity of accurate epidemiological data in official records might have masked the real magnitude of this problem. Our analysis suggests that the problem of snakebite envenoming in Bangladesh might be worse than currently perceived. A long-term sustainable snakebite program plan should be designed and institutionalized, considering climatic, geographical and human demographic variables, to obtain better data and facilitate the implementation of accurate snakebite management programs for this country.

Perceptions on Indigenous Medicine, First Aid and Treatment of Snakebite among Sri Lankan Farmers

Since snakebite is a serious public health concern in Asia, one of the most affected countries is Sri Lanka. The incidence, species variety, clinical symptoms, and management of snakebite in Asia, with a focus on Sri Lanka, are all covered in this review paper. Many of the venomous snake species found in Asia are abundant and diverse. Snake bites are a typical occurrence, especially in rural areas where farming and encounters between humans and snakes are common. Numerous snake species, including the dangerous Russell’s viper and the spectacled cobra, are found in Sri Lanka specifically. Depending on the type of snake bitten and the amount of venom administered, different clinical symptoms might result from a snake bite. Pain, bruising, swelling, and systemic symptoms like nausea, vomiting, and paralysis are typical ones. Treatment that is given too slowly or not at all can result in fatal consequences. Antivenom delivery, wound care, and supportive measures are all essential components of managing snake bite cases effectively. However, obstacles including a lack of access to medical facilities and less availability of antivenom sometimes make it difficult to get treatment quickly, particularly in isolated places and concern about indigenous treatment as well. Public awareness campaigns, better healthcare facilities, and epidemiology research are only a few of the measures taken against snakebite in Sri Lanka. To lessen the number of snakebites in, government institutions, medical professionals, and international organizations must work together. Better antivenom medicines and improved preventive and treatment plans for snakebite in this area require more study and funding.International Journal of Human and Health Sciences Vol. 08 No. 02 Apr’24 Page: 116-125

Attitudes towards snakebite health education and associated factors among residents in China: A national cross-sectional study.

This study aimed to investigate attitudes towards health education on snakebites and to identify the influencing factors among Chinese residents. Additionally, we proposed effective health education strategies for snakebite management. Between May 2022 and February 2023, we conducted a nationwide cross-sectional questionnaire survey using a multistage sampling method with supplementary snowball sampling. We used descriptive analysis, χ2 tests, and univariable and multivariable binary logistic regression models to analyse the data. We included 56 669 respondents in the analysis. The average score for snakebite knowledge was 12.13 ± 5.26 points, with a maximum score of 28. Among the respondents, 72.66 and 63.03% of the residents believed that it was necessary to disseminate knowledge about snakebites and expressed a willingness to receive snakebite training, respectively. Respondents from the northeast region, respondents with a higher education level, and respondents with higher scores for snakebite knowledge, health knowledge, health skills, and social-psychological adjustment skills exhibited more positive attitudes towards snakebite knowledge dissemination and training. Conversely, respondents from eastern or southern China, respondents older than 60, and respondents who lived in rudimentary housing conditions showed a lower perception of the need for snakebite knowledge dissemination and were less willing to participate in snakebite knowledge and skill training. Generally, Chinese residents have positive attitudes towards snakebite knowledge dissemination and training. However, the public lacks sufficient knowledge about snakebites. Therefore, we should pay close attention to areas south of the Yangtze River to strengthen snakebite health education using engaging formats that align with residents' interests, such as short videos or television programmes, in an attempt to and ultimately improve health literacy and prevention awareness.

Antivenom surveillance: An audit of antivenom stock within South Australia.

Antivenoms are important emergency medications to be held within Australia, particularly in regional and remote locations. We audited current antivenom holdings in hospitals and health services across South Australia (SA) and compared to recommendations in the 'Snakebite and Spiderbite Management Guidelines' from the State's Toxinology service. The process also assessed the feasibility of 'real-time' remote stock monitoring. Fifty-three sites listed in the guideline were recommended to hold antivenom, though only 49 are currently operational. Interrogation of antivenom stock for 29 sites was possible using electronic reports generated from the State Pharmacy database. The 20 remaining centres had their stock levels confirmed by calling the centres directly. Data obtained were then compared to recommended levels of antivenom holdings in the guideline with discrepancies and associated costs documented. A separate report verification process was used to determine 'real-time' accuracy of the electronic reports. Thirty-seven sites (75%) held more than the recommended number of antivenom vials, totalling 129 vials in excess with an approximate total cost of $110 000. Twelve sites (24%) held inadequate stock to deliver a treatment dose for 19 envenoming events. The report verification revealed variances in the electronic reports. This audit has demonstrated a significant disparity between recommended and actual antivenom holdings across most sites in SA and has also revealed that 'real-time' remote monitoring of state antivenom holdings is not currently feasible. Correction of stock levels to that recommended may result in financial benefit for State Health while also addressing inequity in regional and remote healthcare provision.

Knowledge in identifying venomous snakes and first aid methods of snakebites among nursing students: A cross-sectional study.

Snakebites are a dangerous and significant medical emergency that occurs worldwide. The World Health Organization has recommended that teaching and training in the prevention and management of snakebites be included in the curriculum of nursing schools and other educational activities. Identification of venomous snakes and first aid would be more critical in the prevention of occupational danger worldwide. This study aims to assess the knowledge in identifying venomous snakes, snakebites, and first aid methods of snakebites among nursing students in the Southern Province of Sri Lanka. A descriptive, cross-sectional study was performed among 425 nursing students who were studying in different educational settings: undergraduates at the University of Ruhuna, and nursing students in the three schools of nursing in Galle, Matara, and Hambantota. Data were gathered by incorporating a pre-tested self-administered questionnaire after obtaining institutional permission. The total score of whole knowledge ranged from 0 to 34 for the identification of venomous snakes. Data collection was performed after obtaining ethical clearance from the Ethics Review Committee, Faculty of Allied Health Sciences, University of Ruhuna, Sri Lanka. Most of the students (82.6%) were in the 24-26 age category and the majority were females. Most of the sample (64.7%) had low knowledge of identifying venomous snakes. A higher percentage of students (57.4%) had a sufficient level of knowledge about first aid methods associated with snakebites and 169 participants (39.8%) had a high level of knowledge regarding first aid methods. Further, a significant impact on students' knowledge and knowledge of first aid methods was reported. The overall knowledge of identifying venomous snakes among the nursing students was inadequate. However, the knowledge about the first aid methods was at a moderate level. Strategies are needed to improve knowledge in identifying venomous snakes and first aid methods of snakebites amongst nursing students in both educational settings.

Venomous snakebites in children: a 10 year experience in South China

Introduction Many studies have focused on snakebites in adults, but very few have described snakebites in children. Methods We reviewed the clinical characteristics and outcomes of children with venomous snakebites aged less than 15 years who presented to a regional medical centre in South China from January 2013 to December 2022. Results A total of 69 envenomed patients were analyzed in our study; 42 (60.9 per cent) patients were male, and 59 (85.5 per cent) reported lower limb bites. Most bites (89.8 per cent) occurred between April and October. Twenty-seven patients received first aid management, and 47 required admission to the general ward. Antivenom was administered to 58 patients, glucocorticoids to 43 patients, antibiotics to 48 patients, and tetanus antitoxin to 40 patients. No fatalities were reported. The most common snake identified was Trimeresurus albolabris. Four were classified as dry bites, 15 as mild, 43 as moderate, and seven as severe. The most common local signs were pain and swelling, while the most common systemic effects were haematological complications. Patients with high severity scores had significantly higher lactate dehydrogenase activities, creatine kinase isoenzyme activities, aspartate aminotransferase activities, D-dimer concentrations, prothrombin times and lower fibrinogen concentrations. In a receiver operating characteristic curve analysis of the values with the highest Youden index, the following cut-offs proved significant: lactate dehydrogenase activity > 248.1 U/L, creatine kinase isoenzyme activities > 17.5 U/L, fibrinogen concentration < 1,455 mg/L, D-dimer concentration > 437.0 µg/L, aspartate aminotransferase activity > 26.1 U/L, and prothrombin time > 15.2 seconds. Discussion This study provides insight into the epidemiology, clinical profile, and management of snakebites in children. Data from the present study were compared with those from our previous adult study. Limitations include that 50.7 per cent of our snakebites were attributed to Trimeresurus albolabris. Therefore, the results of our study may not be generalizable to all snakebites. Conclusion The clinical symptoms were more severe in children than in adults in our previous study. Even though there were no fatalities, close monitoring should be performed to detect haematological and other potentially fatal complications promptly.

Venom diversity in Naja mossambica: Insights from proteomic and immunochemical analyses reveal intraspecific differences.

Intraspecific variations in snake venom composition have been extensively documented, contributing to the diverse clinical effects observed in envenomed patients. Understanding these variations is essential for developing effective snakebite management strategies and targeted antivenom therapies. We aimed to comprehensively investigate venoms from three distinct populations of N. mossambica from Eswatini, Limpopo, and KwaZulu-Natal regions in Africa in terms of their protein composition and reactivity with three commercial antivenoms (SAIMR polyvalent, EchiTAb+ICP, and Antivipmyn Africa). Naja mossambica venoms from Eswatini region exhibited the highest content of neurotoxic proteins, constituting 20.70% of all venom proteins, compared to Limpopo (13.91%) and KwaZulu-Natal (12.80%), and was characterized by the highest diversity of neurotoxic proteins, including neurotoxic 3FTxs, Kunitz-type inhibitors, vespryns, and mamba intestinal toxin 1. KwaZulu-Natal population exhibited considerably lower cytotoxic 3FTx, higher PLA2 content, and significant diversity in low-abundant proteins. Conversely, Limpopo venoms demonstrated the least diversity as demonstrated by electrophoretic and mass spectrometry analyses. Immunochemical assessments unveiled differences in venom-antivenom reactivity, particularly concerning low-abundance proteins. EchiTAb+ICP antivenom demonstrated superior reactivity in serial dilution ELISA assays compared to SAIMR polyvalent. Our findings reveal a substantial presence of neurotoxic proteins in N. mossambica venoms, challenging previous understandings of their composition. Additionally, the detection of numerous peptides aligning to uncharacterized proteins or proteins with unknown functions underscores a critical issue with existing venom protein databases, emphasizing the substantial gaps in our knowledge of snake venom protein components. This underscores the need for enhanced research in this domain. Moreover, our in vitro immunological assays suggest EchiTAb+ICP's potential as an alternative to SAIMR antivenom, requiring confirmation through prospective in vivo neutralization studies.

Optimizing survival in Russell’s viper bite cases in low-resource setting: two case reports

IntroductionSnakebite envenomation poses a significant health risk, particularly in low-resource settings where access to proper treatment is limited.Case presentationThis study reports two cases of Russell's viper bites in rural Bangladesh, involving 48 and 35-year-old Bangladesh males, respectively, and highlights the difficulties in providing adequate medical care and in treating any complications that may arise. Both cases involved delayed access to healthcare, initial visit to traditional healers, and the development of severe complications such as coagulopathy, renal failure. After the intervention both cases survived which is scarce in low resource settings.ConclusionThe cases underscore the importance of early recognition, appropriate management, and improved healthcare infrastructure to optimize survival outcomes in snakebite cases in resource-limited settings. These cases will contribute valuable insights to the field of snakebite management and provide guidance for improving survival rates and outcomes among snakebite victims in Bangladesh.

Multiplex lateral flow assay development for snake venom detection in biological matrices

Bothrops and Lachesis are two of Brazil’s medically most relevant snake genera, causing tens of thousands of bites annually. Fortunately, Brazil has good accessibility to high-quality antivenoms at the genus and inter-genus level, enabling the treatment of many of these envenomings. However, the optimal use of these treatments requires that the snake species responsible for the bite is determined. Currently, physicians use a syndromic approach to diagnose snakebite, which can be difficult for medical personnel with limited training in clinical snakebite management. In this work, we have developed a novel monoclonal antibody-based multiplex lateral flow assay for differentiating Bothrops and Lachesis venoms within 15 min. The test can be read by the naked eye or (semi)-quantitatively by a smartphone supported by a 3D-printed attachment for controlling lighting conditions. The LFA can detect Bothrops and Lachesis venoms in spiked plasma and urine matrices at concentrations spanning six orders of magnitude. The LFA has detection limits of 10–50 ng/mL in spiked plasma and urine, and 50–500 ng/mL in spiked sera, for B. atrox and L. muta venoms. This test could potentially support medical personnel in correctly diagnosing snakebite envenomings at the point-of-care in Brazil, which may help improve patient outcomes and save lives.
