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.

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. At the global level, there is insufficient manufacturing output to meet clinical needs, notably for antivenoms intended for use in regions with a scarcity of producers. At national level, variable funding and deficient regulation of certain antivenom markets can lead to the procurement of substandard antivenom. This is particularly true when producers fail to seek registration of their products in the countries where they should be used, or where weak assessment frameworks allow registration without local clinical evaluation. Out-of-pocket expenses by snakebite victims are often the main source of financing antivenoms, which results in the underuse or under-dosing of antivenoms, and a preference for low-cost products regardless of efficacy. In resource-constrained rural areas, where the majority of victims are bitten, supply of antivenom in peripheral health facilities is often unreliable. Misconceptions about treatment of snakebite envenoming are common, further reducing demand for antivenom and exacerbating delays in reaching facilities equipped for antivenom use.

Snakebite is a major public health burden for low-income countries in tropical parts of the world. There are around 5 million bites and , deaths every year. And about , victims become permanently disabled annually. In Africa, the most notorious of snake species is the black mamba Dendroaspis polylepis. It is feared for its potent rapid-acting venom and its characteristic feature of typically striking more than once. The problem is that it always injects venom in its bite.

Antivenom , also known as antivenin , venom antiserum , and antivenom immunoglobulin , is a specific treatment for envenomation. It is composed of antibodies and used to treat certain venomous bites and stings. Side effects may be severe. Versions are available for spider bites , snake bites , fish stings , and scorpion stings. Antivenom was first developed in the late 19th century and came into common use in the s. Antivenom is used to treat certain venomous bites and stings. In the US, approved antivenom, including for pit viper rattlesnake , copperhead and water moccasin snakebite, is based on a purified product made in sheep known as CroFab.

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. Thus, it is important that antivenom treatment start as quickly as possible. Depending on the amount and toxicity of the venom, a victim may need many injections of antivenom to sufficiently neutralize the venom. Antivenom must be tailored to combat the venom of a particular species. This ca s snake-bite kit relies on first using a tourniquet to restrict the flow of venom from the wound into the bloodstream.

Available products are usually ineffective in such instances despite the administration of large doses, and carry a high concomitant risk of allergic reactions Ralph et al. At national level, variable funding and deficient regulation of certain antivenom markets can lead to the procurement of substandard antivenom. At the same time, more rational use has also been reported after implementation of new treatment protocols, notably in Bangladesh and India Harris et al. View Article Google Scholar 8. Our analysis is restricted to antivenom access but we also recognize the importance of access to good ancillary care alongside other components of SBE management. Humanitarian organizations are often best prepared to provide antivenom therapy during humanitarian emergencies, particularly natural disasters and other crises causing population displacement, which carry a high risk of both snakebite epidemics and disruption of health services and medical supply chains Ochoa et al. All costs are in Nigerian Naira. Within this ecosystem, it is not surprising that chronic shortages of antivenom are reported in regions with high burdens of SBE and a small number of producers [see Fig. In any case, this is far below the global need to treat 2. In addition, in our model, antivenoms reduce the risk of mortality only, although it is plausible that they may also reduce the risk of disability related endpoints such as amputations. The variability of products, even from one batch to another, can result in considerable uncertainty when it comes to estimating dose at the bedside [See Box 2 ].

A recombinant antivenom, based on a mixture of human antibodies, would be designed in a way that the antibodies would be specifically selected to target the most relevant toxins in snake venom. Toxicon X. Examples exist for other products: the Strategic Fund for the acquisition of Essential Medicines and the Revolving Fund of Vaccines of the Pan American Health Organization consolidate procurement on behalf of participating countries in the Americas, and the International Coordination Group on Vaccine provision manages stockpiles of vaccines for prompt delivery for outbreak response DeRoeck et al.
