REVIEW
Josée Bouchard, Ravindra L Mehta
BACKGROUND: Acute kidney injury (AKI) is frequent and is associated with poor outcomes, including increased mortality, higher risk of chronic kidney disease, and prolonged hospital lengths of stay. The epidemiology of AKI mainly derives from studies performed in Western high-income countries. More limited data are available from Western low-income and middle-income countries (LMICs) located in Central and South America. SUMMARY: In this review, we summarize the most recent data on the epidemiology of AKI in Western countries, aiming to contrast results from industrialized high-income countries with LMICs...

The purpose of this study was to evaluate the effect of two administration methods of a biostimulatory homeopathic complex (Convert H(®)) on the production of fresh and lyophilized venom of rattlesnakes (Crotalus durissus) under intensive captivity conditions. Sixty snakes were subjected to treatment following a randomized block design. The effects of sex and size were controlled for. Thirteen consecutive extractions were performed over 21 months. The first factor considered in the experiment was the origin of mice used as prey: a conventional colony (A1) or the Convert H colony (A2; mice receiving the homeopathic complex in water at 1%)...

Snake bite envenomations are common in rural areas and the incidence peaks during monsoons in India. Prominent venomous species have been traditionally labeled as the 'big four' that includes Cobra, Krait, Russel's viper and Saw scaled viper. Systematic attempts for identification and classification of prevalent snakes in various states of India are missing till now and there is no concrete data on this aspect. The published literature however shows that some species of snakes are more prevalent in a particular region than the other parts of India e...

Rattlesnake envenomation causes a spectrum of symptoms and signs, many of which closely resemble an anaphylactic reaction. Development of airway compromise after a snake bite to an extremity is unusual, but has been previously reported. The majority of such reports detail a history of probable sensitization from previous contact with snakes or snake venom. Few reports exist without such previous contact; no reports are of pediatric cases. Here we present a 14-year-old boy with no history of prior snake exposure who presents with an anaphylactoid reaction after a rattlesnake bite...

Venom secretions from snakes, scorpions, spiders and bees, have been widely applied in traditional medicine and current biopharmaceutical research. Possession of anticancer potential is another novel discovery for animal venoms and toxins. An increasing number of studies have shown the anticancer effects of venoms and toxins of snakes, and scorpions in vitro and in vivo, which were achieved mainly through the inhibition of cancer growth, arrest of cell cycle, induction of apoptosis and suppression of cancer metastasis...

Bothrops erythromelas is a snake of medical importance responsible for most of the venomous incidents in Northeastern Brazil. However, this species is not included in the pool of venoms that are used in the Brazilian polyvalent bothropic antivenom (BAv) production. Furthermore, it is well known that antivenom therapy has limited efficacy against venom-induced local effects, making the search for complementary alternatives to treat snakebites an important task. Jatropha gossypiifolia is a medicinal plant widely indicated in folk medicine as an antidote for snakebites, whose effectiveness against Bothrops jararaca venom (BjV) has been previously demonstrated in mice...

Snakebite is a serious occupational hazard affecting mainly rural populations of tropical and subtropical developing countries. Lachesis muta (Bushmaster) bites are extremely serious but are rarely reported in the literature. Bushmaster envenomings are characterized by intense local pain, edema, neurotoxicity, hypotension, local hemorrhage, and dramatic systemic alterations. Antivenom treatment has regularly been used for more than a century; however, it fails to neutralize local tissue damage and hemorrhage, leading to morbidity or disabilities in victims...

Tumor necrosis factor (TNF)-α is a pleiotropic cytokine with intense pro-inflammatory and immunomodulatory properties, and anti-TNF-α biologics are effective therapies for various inflammatory diseases such as inflammatory bowel disease (IBD) and sepsis. Snake venom, as a traditional Chinese medicine, has been used in the treatment of inflammatory diseases in China for centuries. In this research, we constructed a venom gland T7 phage display library of the sea snake Hydrophis cyanocinctus to screen bioactive compounds that antagonize TNF-α and identified a novel nine-amino-acid peptide, termed hydrostatin-TL1 (H-TL1)...

BACKGROUND: Snake venoms are great sources of bioactive molecules, which may be used as models for new drugs. Toxins that interfere in hemostasis have received considerable attention over the years. OBJECTIVES: This study aimed at the evaluation of the antithrombotic activity of Batroxase, a P-I metalloprotease from Bothrops atrox venom, in an animal model of venous thrombosis. METHODS: The antithrombotic activity of Batroxase was tested in vivo in a model based on two factors of the Virchow's Triad: blood flow alterations (partial stenosis of the inferior vena cava), and vessel wall injury (10% ferric chloride for 5min), in comparison with sodium heparin (positive control) and saline (negative control)...

Snakebite is an important medical problem in Sri Lanka. Of the deadly venomous snakes, Russell's viper (Daboia russelii) is widely distributed and responsible for most of the fatalities of snakebite in the country. It is not uncommon to see atypical manifestations in Russell's viper bite. We report the events of intracranial haemorrhages and multiple ischemic brain infarcts following Russell's viper (Daboia russelii) bite of a previously healthy 43-years-old male who succumbed to envenoming.

Serum Anti Ular Bisa (SABU) is the only snake antivenom produced locally in Indonesia; however, its effectiveness has not been rigorously evaluated. This study aimed to assess the protein composition and neutralization efficacy of SABU. SDS polyacrylamide gel electrophoresis, size-exclusion liquid chromatography and shotgun proteomics revealed that SABU consists of F(ab')2 but a significant amount of dimers, protein aggregates and contaminant albumins. SABU moderately neutralized Calloselasma rhodostoma venom (potency of 12...

This allergic reaction to snake venom was described to occur in patients after recurrent exposure through bites in amateur and professional snake handlers, which might be underestimated and contribute to fatal snakebites in victim, independently from the toxicity of the venom itself. Few allergens were identified from snake venoms by normal SDS-PAGE, which cannot separate the snake venom completely. In the present study, we identified nine potential allergens by two-dimensional (2D) electrophoresis followed by immunoblotting (named as allergenomics) in Protobothrops mucrosquamatus venom...

Components from animal venoms may vary according to the snake's age, gender and region of origin. Recently, we performed a proteomic analysis of Bothrops jararaca venom from southern (BjSv) and southeastern (BjSEv) Brazil, showing differences in the venom composition, as well as its biological activity. To continue the study, we report in this short communication the different effects induced by the BjSEv and BjSv on isolated kidney and MDCK renal cells. BjSEv decreased perfusion pressure (PP) and renal vascular resistance (RVR) and increased urinary flow (UF) and glomerular filtration rate (GFR), while BjSv did not alter PP and RVR and reduced UF and GFR...

Snakebites are a serious worldwide public health problem. In Brazil, about 90% of accidents are attributed to snakes from the Bothrops genus. The specific treatment consists of antivenom serum therapy, which has some limitations such as inability to neutralize local effects, difficult access in some regions, risk of immunological reactions, and high cost. Thus, the search for alternative therapies to treat snakebites is relevant. Jatropha mollissima (Euphorbiaceae) is a medicinal plant popularly used in folk medicine as an antiophidic remedy...

Limb adorning ornaments (LAO) can exacerbate the local effects of envenoming in case of venomous snake bite. Cultural presuppositions do inhibit victims from removing symbolically/ritually important jewelry even under circumstances that might increase the dangers of envenoming-induced gangrene formation. The recommendation to remove the LAO is usually skipped in guidelines and if at all included the very real hazard is uncommonly documented. We observed 14 cases of snake bite with LAO on the bitten limb with minimal to severe local complications...

In our earlier report, gold nanoparticle (GNP) and snake venom protein toxin NKCT1 were conjugated and primary characteristics were done. In this communication, further characteristics of GNP-NKCT1 were done with TGA, BET, Zeta potential, ICP-MS, FTIR, XPS, and in vitro release kinetics for its physicochemical, molecular nature and bonding. TGA and ICP-MS showed that the number of conjugation was 40 ± 5 to 90 ± 8 NKCT1 per gold nanoparticles. FTIR and XPS corresponding to (CO), (NH), (SS) reformulated the conjugation of GNP with NKCT1...
