Role of the animal model on the pharmacokinetics of equine-derived antivenoms
(2013-08)
Antivenom pharmacokinetics has been studied in heterologous models in which the animal species used as immunoglobulin source is different from that used as recipient. In these models, after intravenous administration of ...
Anticomplementary activity of equine whole IgG antivenoms: comparison of three fractionation protocols
(2005-01)
Early adverse reactions occur in a number of patients treated with heterologous antivenoms and have been associated with anticomplementary activity (ACA). In order to reduce the ACA of equine whole IgG antivenoms produced ...
Pharmacokinetics of whole IgG equine antivenom: comparison between normal and envenomed rabbits
(2006-09-01)
Pharmacokinetics of antivenoms has been mainly studied in normal animals, whereas very little is known on pharmacokinetics in envenomed animals. The aim of this study was to compare pharmacokinetic parameters of whole IgG ...
Human heterophilic antibodies against equine immunoglobulins: assessment of their role in the early adverse reactions to antivenom administration
(2008)
The presence of human heterophilic antibodies against horse immunoglobulins
(HHA-HI) was determined by ELISA in sera from healthy volunteers and from patients who
received equine antivenom for therapy of snake bite ...
Equine antibodies to Bothrops asper myotoxin II: isolation from polyvalent antivenom and neutralizing ability.
(1990)
Equine antibodies to
B. riper myotoxin II were isolated from polyvalent antivenom by affinity
chromatography. Purified antibodies were among the most acidic serum
immunoglobulins, migrating between the ß- and aZ-globulin ...
Turbidity of hyperimmune equine antivenom: the role of phenol and serum lipoproteins
(1993)
Twenty batches of polyvalent antivenom produced at the Instituto Clodomiro Picado were analyzed for turbidity, both before and after freezing-thawing and lyophilization. Eight batches became turbid upon freezing-thawing, ...
Development of a chicken-derived antivenom against the taipan snake (Oxyuranus scutellatus) venom and comparison with an equine antivenom
(2016-09-15)
A chicken-derived antivenom (ChDAv) towards taipan snake (Oxyuranus scutellatus) venom was produced
by purifying anti-taipan IgY from egg yolks of hens immunized with taipan venom. The productivity,
antivenomic profile, ...
Intravenous administration of equine-derived whole IgG antivenom does not induce early adverse reactions in non-envenomed horses and cows
(2010-11)
Administration of antivenoms to treat snakebite envenomings has the potential risk of inducing early adverse reactions. The mechanisms involved in these reactions are unclear. In this study, polyspecific antivenom consisting ...
Assessment of the viral safety of antivenoms fractionated from equine plasma
(2004-09)
Antivenoms are preparations of intact or fragmented (F(ab')2 or Fab) immunoglobulin G (IgG) used in human medicine to treat the severe envenomings resulting from the bites and stings of various animals, such as snakes, ...
Stability of equine IgG antivenoms obtained by caprylic acid precipitation: Towards a liquid formulation stable at tropical room temperature
(2009-05)
Liquid formulations of antivenom require a cold chain for their distribution and storage, especially in tropical countries characterized by high temperature and humidity (climatic zone IV). Since cold chain is often deficient ...
