Abstract
Background Wasp stinging, a neglected tropical entity can have a myriad of local and systemic effects. We present a case of multi-organ injury following multiple wasp stings and a review of literature on the systemic manifestations of wasp stings.
Case presentation A 48-year-old Sri Lankan male who suffered multiple wasp stings, developed an anaphylactic shock with respiratory failure, which was treated with adrenaline and mechanical ventilation. Within the next 2 days the patient developed acute fulminant hepatitis, stage III acute kidney injury, rhabdomyolysis, haemolysis and thrombocytopenia. The patient was treated in the intensive care unit with ionopressors and continuous renal replacement therapy (CRRT). Haemoadsorbant therapy was used in adjunct with CRRT. There was a gradual recovery of the organ functions over the 1st week. However, the patient succumbed to fungal sepsis on the 16th day despite treatment. We conducted a literature review to identify the various clinical manifestations of wasp stinging. Wasp venom contains enzymes, amines, peptides and other compounds. These proteins can cause type 1 hypersensitive reactions ranging from local skin irritation to anaphylactic shock. Furthermore, the toxins can cause direct organ injury or delayed hypersensitivity reactions. The commonly affected organs are the kidneys, liver, and muscles. The effect on the haematological system manifests as coagulopathy and/or cytopenia. The heart, nervous system, lungs, intestines and skin can be affected rarely. Treatment is mainly supportive. Conclusion In conclusion, wasp envenomation can result in multi-organ injury and attention should be paid in doing further research and establishing evidence-based treatment practices.

Abstract
Agelaia-MPI and protonectin are antimicrobial peptides isolated from the wasp Parachartergus fraternus that show antimicrobial and neuroactive activities. Previously, two analogues of these peptides, neuroVAL and protonectin-F, were designed to reduce nonspecific toxicity and improve potency. Here, the three-dimensional structures of neuroVAL, protonectin and protonectin-F were determined by using circular dichroism and NMR spectroscopy. Antibacterial, antifungal, cytotoxic and hemolytic activities were tested for the parent peptides and analogues. All peptides showed moderate antimicrobial activity against Gram-positive bacteria, with agelaia-MPI being the most active. Protonectin and protonectin-F were found to be toxic to cancerous and noncancerous cell lines. Internalization experiments revealed that these peptides accumulate inside both cell types. By contrast, neuroVAL was nontoxic to all tested cells and was able to enter cells without accumulating. In summary, neuroVAL has potential as a nontoxic cell-penetrating peptide, while protonectin-F needs further modification to realize its potential as an antitumor peptide.

Pro-inflammatory response induced by the venom of Parachartergus fraternus wasp. Toxicon 2020; 190:11-19. [PMID: 33290790 DOI: 10.1016/j.toxicon.2020.11.176] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Revised: 10/30/2020] [Accepted: 11/30/2020] [Indexed: 01/17/2023]
Abstract
The sting of different wasp species triggers local and systemic reactions in victims that can lead to death. Parachartergus fraternus is responsible for frequent accidents in Latin America; however, few studies have been conducted on this insect and its venom. In this study, the inflammatory process induced by the venom of the P. fraternus wasp (Pfv; 100, 200, and 400 μg/kg) was characterized. Mice were used to assess paw edema, vascular permeability, mast cell degranulation, leukocyte influx, nitric oxide (NO) production, expression of inflammatory genes, and histopathological changes. Pfv triggered edema formation with a peak dose of 200 μg/kg at 10 min. There was an increase in permeability in all periods and doses evaluated, with no differences between them. The 200 μg/kg dose induced mast cell degranulation in all periods, with a peak at 15 min. This same dose induced leukocyte influx with a predominance of mononuclear cells and triggered a peak in NO production in the 12th hour. The increase in COX-2, iNOS, and IFN-γ mRNA expression occurred after 1 and 6 h, and there was an increase in IL-10 expression after 48 h. In addition, Pfv triggered edema and induced an influx of macrophages and mast cells into the injection site. Therefore, Pfv induces an inflammatory process from the first 5 min of inoculation that can persist for up to 48 h.

Anthelminthic Activity of Assassin Bug Venom against the Blood Fluke Schistosoma mansoni. Antibiotics (Basel) 2020; 9:antibiotics9100664. [PMID: 33019687 PMCID: PMC7599792 DOI: 10.3390/antibiotics9100664] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 09/23/2020] [Accepted: 09/28/2020] [Indexed: 12/12/2022] Open
Abstract
Helminths such as the blood fluke Schistosoma mansoni represent a major global health challenge due to limited availability of drugs. Most anthelminthic drug candidates are derived from plants, whereas insect-derived compounds have received little attention. This includes venom from assassin bugs, which contains numerous bioactive compounds. Here, we investigated whether venom from the European predatory assassin bug Rhynocoris iracundus has antischistosomal activity. Venom concentrations of 10–50 µg/mL inhibited the motility and pairing of S. mansoni adult worms in vitro and their capacity to produce eggs. We used EdU-proliferation assays to measure the effect of venom against parasite stem cells, which are essential for survival and reproduction. We found that venom depleted proliferating stem cells in different tissues of the male parasite, including neoblasts in the parenchyma and gonadal stem cells. Certain insect venoms are known to lyse eukaryotic cells, thus limiting their therapeutic potential. We therefore carried out hemolytic activity assays using porcine red blood cells, revealing that the venom had no significant effect at a concentration of 43 µg/mL. The observed anthelminthic activity and absence of hemolytic side effects suggest that the components of R. iracundus venom should be investigated in more detail as potential antischistosomal leads.

Abstract
Poisonous animals imply a risk to human life, because their venom is a complex mixture of low molecular weight components, peptides and proteins. Hornets use the venom for self-defence, to repel intruders and to capture prey, but they can cause poisoning and allergic reactions to people. In particular, they seem to be a health problem in the countries where they are native due to their sting, which in the most severe cases can lead to severe or fatal systemic anaphylaxis. But this situation is being an emerging problem for new countries and continents because hornet incursions are increasing in the global change scenario, such as in Europe and America. Furthermore, 55 detailed cases of hornet sting were found in 27 papers during the current review where 36.4% died due to, mainly, a multi-organ failure, where renal failure and liver dysfunction were the most common complications. Moreover, the great taxonomic, ecological diversity, geographical distribution and the wide spectrum of pathophysiological symptoms of hornets have been the focus of new research. Considering this, the present systematic review summarizes the current knowledge about the components of Vespa venom and the epidemiology of its sting to serve as reference for the new research focused on the development of techniques for diagnosis, new drugs and treatments of its sting.

Abstract
Pain is a natural bioassay for detecting and quantifying biological activities of venoms. The painfulness of stings delivered by ants, wasps, and bees can be easily measured in the field or lab using the stinging insect pain scale that rates the pain intensity from 1 to 4, with 1 being minor pain, and 4 being extreme, debilitating, excruciating pain. The painfulness of stings of 96 species of stinging insects and the lethalities of the venoms of 90 species was determined and utilized for pinpointing future directions for investigating venoms having pharmaceutically active principles that could benefit humanity. The findings suggest several under- or unexplored insect venoms worthy of future investigations, including: those that have exceedingly painful venoms, yet with extremely low lethality—tarantula hawk wasps (Pepsis) and velvet ants (Mutillidae); those that have extremely lethal venoms, yet induce very little pain—the ants, Daceton and Tetraponera; and those that have venomous stings and are both painful and lethal—the ants Pogonomyrmex, Paraponera, Myrmecia, Neoponera, and the social wasps Synoeca, Agelaia, and Brachygastra. Taken together, and separately, sting pain and venom lethality point to promising directions for mining of pharmaceutically active components derived from insect venoms.

Abstract
Stinging accidents involving wasp venom are a notable cause of acute kidney injury (AKI) in Asia. However, very little attention has been paid to the understanding of the mechanisms involved in this type of AKI. The aims of this review are to explore the evidence for the mechanisms and the therapeutic role of renal replacement therapy of wasp venom and AKI. A systematic literature search was conducted using PubMed for the association among wasp venom and AKI. Wasp venom is a complex mixture of biologically active components, including enzymes, amines, and peptides. Wasp venom may induce local anaphylaxis reactions as well as systemic reactions such as AKI. AKI may develop as a result of direct nephrotoxic effects of the venom or secondary intravascular hemolysis and/or rhabdomyolysis. Histopathological features of renal biopsies predominantly include acute tubular necrosis and acute interstitial nephritis. Renal replacement therapy, which includes intermittent hemodialysis, hemoperfusion, plasmapheresis, continuous renal replacement therapy, and peritoneal dialysis, has been used to treat severe AKI cases induced by wasp stings. Continuous renal replacement therapy appears to provide more benefit than intermittent hemodialysis in the treatment of wasp sting-induced AKI. In this review, we summarize the existing evidence of the mechanisms and treatment for venom-induced AKI, with a particular emphasis on the role of renal replacement therapy in the management of severe AKI following massive wasp stings.

Abstract
Nature has been the source of life-changing and -saving medications for centuries. Aspirin, penicillin and morphine are prime examples of Nature׳s gifts to medicine. These discoveries catalyzed the field of natural product drug discovery which has mostly focused on plants. However, insects have more than twice the number of species and entomotherapy has been in practice for as long as and often in conjunction with medicinal plants and is an important alternative to modern medicine in many parts of the world. Herein, an overview of current traditional medicinal applications of insects and characterization of isolated biologically active molecules starting from approximately 2010 is presented. Insect natural products reviewed were isolated from ants, bees, wasps, beetles, cockroaches, termites, flies, true bugs, moths and more. Biological activities of these natural products from insects include antimicrobial, antifungal, antiviral, anticancer, antioxidant, anti-inflammatory and immunomodulatory effects.

Abstract
Currently, new antimicrobial molecules extracted or obtained by natural sources, could be a valide alternative to traditional antibiotics. Most of these molecules are represented by antimicrobial peptides (AMPs), which are essential compounds of insect, arachnids and centipedes venom. AMPs, due to their strong effectiveness, low resistance rates and peculiar mode of action, seem to have all the suitable features to be a powerful weapon against several bacteria, especially considering the increasing antibiotic-resistance phenomena. The present literature review focuses on the antibacterial activity of bee, wasp, ant, scorpion, spider and scolopendra crude venom and of their main biological active compounds. After a brief overview of each animal and venom use in folkloristic medicine, this review reports, in a comprehensive table, the results obtained by the most relevant and recent researches carried out on the antibacterial activity of different venom and their AMPs. For each considered study, the table summarizes data concerning minimal inhibitory concentration values, minimal bactericidal concentration values, the methods employed, scientific name and common names and provenience of animal species from which the crude venom and its respective compounds were obtained.

Abstract
Pathological anxiety is among the most common psychiatric illnesses, but current treatment is highly limited. In this study, we investigated the potential anxiolytic-like effects of a peptide isolated from Synoeca surinama venom. Rats treated with this peptide spent more time exploring the open arms of elevated plus maze, which indicates an anxiolytic-like profile for this peptide. This study is the first to show the pharmacological use of S. surinama venom in the treatment of anxiety.

Abstract
BACKGROUND Tarantulas (Theraphosidae) represent an important source of novel biologically active compounds that target a variety of ion channels and cell receptors in both insects and mammals. In this study, we evaluate and compare the pharmacological activity of venoms from three taxonomically different theraphosid spiders bred in captivity: Poecilotheria regalis, an aggressive arboreal tarantula from southeastern India; Ceratogyrus darlingi, an aggressive tarantula from southern Africa; and Brachypelma epicureanum, a docile tarantula from the Yucatan dry forest of Mexico. Prior to this study, no research had been conducted with regard to the composition and pharmacological activity of these venoms. METHODS The pharmacological characterization of the venoms was described for the first time by the assessment of their toxicity in crickets (LD50) along with their nociceptive (by using the formalin test), hyaluronidase, phospholipase A2, edematogenic and caseinolytic activity. RESULTS P. regalis and B. epicureanum venoms induced a similar lethal effect on crickets (LD50 = 5.23 ± 3.1 and 14.4 ± 5.0 μg protein/g 48 h post-injection, respectively), whereas C. darlingi venom (119.4 ± 29.5 μg protein/g 48 h post-injection) was significantly less lethal than the other two venoms. All three venoms induced similar edematogenic activity on rats but did not induce nociceptive behavior. The assessment of enzymatic activity indicated that P. regalis venom induces significantly higher hyaluronidase activity (27.6 ± 0.9 TRU/mg) than both C. darlingi (99.7 ± 1.9 TRU/mg) and B. epicureanum (99.6 ± 1.6 TRU/mg); these latter venoms did not display phospholipase A2 or caseinolytic activity. CONCLUSIONS This study demonstrates that these theraphosid spiders of different habitats produce venoms with different activities. P. regalis venom displays a high level of hyaluronidase activity, which may be associated with its potentially medically significant bite.
