Federal government websites often end in. The site is secure. Heitor Vieira Dourado, Manaus, Brazil. Access to safe, effective, quality-assured antivenom products that are tailored to endemic venomous snake species is a crucial component of recent coordinated efforts to reduce the global burden of snakebite envenoming. Multiple access barriers may affect the journey of antivenoms from manufacturers to the bedsides of patients. Our review describes the antivenom ecosystem at different levels and identifies solutions to overcome these challenges.

Snakebite envenoming is a major public health problem throughout the rural tropics. Antivenom is effective in reducing mortality and remains the mainstay of therapy. This study aimed to determine the cost-effectiveness of using effective antivenoms for Snakebite envenoming in Nigeria. Economic analysis was conducted from a public healthcare system perspective. Estimates of model inputs were obtained from the literature. A decision analytic model was developed and analyzed with the following model base-case parameter estimates: type of snakes causing bites, antivenom effectiveness to prevent death, untreated mortality, risk of Early Adverse Reactions EAR , mortality risk from EAR, mean age at bite and remaining life expectancy, and disability risk amputation. Expanding access to effective antivenoms to larger segments of the Nigerian population should be a considered a priority. Snake bite is a major public health problem throughout rural communities in West Africa and leads to a significant number of deaths and disabilities per year. Even though effective antivenoms exist against the locally prevalent carpet viper and other poisonous snakes, they are generally not available in community settings, possibly because of their high acquisition cost. We evaluated the cost-effectiveness of making antivenom more broadly available in Nigeria by comparing the treatment costs associated with antivenom therapy against their medical benefit in reducing the risk of mortality. Both of these suggest that snakebite antivenom is highly cost-effective in Nigeria and they also compare very favorably against other commonly funded health interventions for which similar estimates exist. Since a substantial reduction in mortality and DALYs could be achieved at a relatively modest upfront cost, expanding access to antivenom to broader parts of the population should be a priority consideration for future investments in healthcare.

Variable policies on use, distribution and clinical environments antivenom ++ access by limiting the number and types of health facilities where antivenom can be held and used. When SBE risk is not uniformly distributed in a region of interest, modeling the vulnerability of the population to SBE can be instrumental in helping to plan antivenom distribution and referral networks Longbottom et al, antivenom ++.

The bite or sting of a highly venomous animal can inflict great suffering, including loss of limbs, paralysis, and an extremely painful death. In the United States, envenomation the injection of venom usually happens during an encounter with a snake, spider, or insect. Antivenom is still produced by much the same method that was developed in the s to produce antitoxins for diphtheria and tetanus. An animal, such as a horse or goat, is injected with a small amount of venom. The blood serum or plasma is then concentrated and purified into pharmaceutical-grade antivenom. Although Antivenom can prevent venom-induced damage to a body, it is less able to reverse damage already wreaked by the venom.

Snake antivenom is a medication made up of antibodies used to treat snake bites by venomous snakes. It is a biological product that typically consists of venom neutralizing antibodies derived from a host animal, such as a horse or sheep. The host animal is hyperimmunized to one or more snake venoms, a process which creates an immunological response that produces large numbers of neutralizing antibodies against various components toxins of the venom. Antivenoms are typically produced using a donor animal, such as a horse or sheep. The donor animal is hyperimmunized with non-lethal doses of one or more venoms to produce a neutralizing antibody response. Then, at certain intervals, the blood from the donor animal is collected and neutralizing antibodies are purified from the blood to produce an antivenom. Snake antivenom can be classified by which antigens venoms were used in the production process.

Registration at country level is essential for national procurement agencies to have confidence that products are safe, effective and truly adapted to the medically most important snake species in the country. Similarly, specific products to neutralize venoms of hump-nosed pit vipers Hypnale hypnale , the commonest cause of snakebite envenoming in Sri Lanka, do not exist. Best viewed in x resolution or higher. Management and cost of snakebite injuries at a teaching and referral hospital in Western Kenya. Inclusion of antivenoms in joint assessment initiatives would change the landscape considerably, inviting greater participation by manufacturers Arik et al. Epidemiological studies in Nigeria and a review of world literature Acta Tropica — A recent review observed that regulatory affairs-related antivenom issues were rarely discussed in peer-reviewed literature Di Fabio et al. Historically SBE has been considered a local issue by the majority of health authorities in affected countries. Brown , n, o and David J. Such a mechanism would however depend on a continuous and sustainable provision of antivenoms. Weaknesses in national regulatory capacity and some manufacturing processes lead to procurement of substandard antivenoms. The antivenom supply crisis is however not uniform. The Collaborative Registration Procedure has been designed by the WHO to aid in precisely this process: to accelerate registration of prequalified essential medicines in multiple countries Ahonkhai et al. Within this context, LMICs would benefit from multilateral antivenom procurement mechanisms.

Management of Snakebite and Research. Landscape of research, production, and regulation in venoms and antivenoms: a bibliometric analysis. Protection against venom of Ophiophagus hannah, Bungarus fasciatus and probably Calliophis and Hemibungarus species, Indian Trimeresurus species. Antivenom quality A recent review observed that regulatory affairs-related antivenom issues were rarely discussed in peer-reviewed literature Di Fabio et al. With limited healthcare resources and competing priorities, it may be useful to compare our estimates to those reported in other therapeutic areas. Evidence of poor preclinical efficacy Calvete et al. Unfortunately, antivenom availability and accessibility remain distant possibilities for large proportions of at-risk populations around the world. Under the WHO strategy for snakebite envenoming, a formal prequalification procedure to support procurement of quality-assured products will be developed within the next 3—4 years Williams et al. Antivenom manufacturing represents an exceptionally heterogeneous industry. Lancet Infect. S1 Text. Countries that lack local manufacturing capacity are particularly vulnerable if the antivenoms used are unregistered and lack marketing authorization.
