Hot-Water Immersion (HWI) or Ice-Pack Treatment (IPT) as First Aid for Human Envenomation by Marine Animals? Review of Literature. Toxins (Basel) 2024; 16:273. [PMID: 38922167 PMCID: PMC11209160 DOI: 10.3390/toxins16060273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2024] [Revised: 06/11/2024] [Accepted: 06/13/2024] [Indexed: 06/27/2024] Open
Abstract
Envenomation by marine animals poses a significant health concern globally, affecting both local residents and tourists in coastal regions. The primary objective of this review is to critically evaluate the existing scientific literature to determine the most effective first-aid treatment for envenomations caused by marine animals, specifically whether hot-water immersion (HWI) or ice-pack treatment (IPT) provides the best immediate care. This comprehensive review covers a wide range of marine envenomations, from jellyfish stings to stingray injuries. While our focus is primarily on the efficacy of HWI and IPT, we also explore the role of cold-water treatment as a result of its relevance and similarity to ice-pack applications. In addition, we examine other treatments mentioned in the literature, such as medications or vinegar, and highlight their findings where applicable. To provide a clear and structured overview, we summarised the articles in separate tables. These tables categorise the type of research conducted, the marine species studied, the region of origin of the marine species, and the key findings of each study. Our analysis of the available evidence indicates a general consensus in the scientific community on the effectiveness of HWI or IPT for envenomation by marine animals. However, when treating those injuries, it is crucial to consider all factors since there is no universally superior treatment due to the diverse nature of marine habitats.

Activities of the Sea Urchin Echinometra mathaei Crude Venoms
from the Persian Gulf-Bushehr. THE NATURAL PRODUCTS JOURNAL 2024; 14. [DOI: 10.2174/2210315514666230622144244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Revised: 04/14/2023] [Accepted: 05/15/2023] [Indexed: 12/08/2023]
Abstract
Background:
Echinoderms are a unique source of amazing secondary metabolites with a wide
spectrum of biological activities. Several species of sea urchins contain various toxins and biologically
active metabolites. One of the most attractive approaches to treat Alzheimer's disease is searching for
effective marine natural products with cholinesterase inhibitory activities.
Objective:
The current study is designed to investigate the in vitro and in silico acetylcholinesterase and
butyrylcholinesterase inhibitory activities of the Persian Gulf echinoderm sea urchin Echinometra
mathaei venom and related chemical compounds.
Methods:
The experiments for LD50, total protein, protein bands, in vitro cholinesterase inhibitory activities,
the identity of secondary metabolites, and the in silico evaluations, respectively, were performed by
Spearman-Karber, Lowry, SDS-PAGE, Ellman's spectroscopic, GC-MS, and docking methods.
Results:
The LD50 (IV rat) of the spine, gonad, and coelomic fluid from sea urchin samples were 2.231 ±
0.09, 1.03 ± 0.05, and 1.12 ± 0.13 mg/ml, respectively. The SDS-PAGE and total protein studies showed
that at least a portion of the venom is protein in nature. GC-MS analysis of the identified samples revealed
12, 23, and 21 compounds with different chemical types, including alkaloids, terpenes, and steroids,
respectively. According to the results, all samples act as significant inhibitors of both enzymes. In
silico data for the identified compounds also confirmed the experimental results.
Conclusion:
The alkaloid compound 6H-Indolo[3,2,1-de] [1,5] naphthyridine-6-one,1,2,3a,4,5-
hexahydro-8-hydroxy-3-methyl (C7) had the highest affinity for both enzymes. Further research is needed
to determine whether C7 could be a therapeutic candidate for Alzheimer's disease.

Abstract
Background Some sea anemone toxins cause renal injuries resembling hemolytic uremic syndrome (HUS). To date, only a few cases of HUS caused by sea anemone stings have been reported. In this case report, we have described an HUS case caused by a sea anemone sting. Case presentation In November 2019, a 37-year-old man with no underlying disease was admitted to our hospital. He presented with intense pain, a rash on, and swelling in his right thigh. Two days prior, he had been stung by a sea anemone while scuba diving in Cebu, Philippines. His blood tests revealed renal dysfunction, and his platelet count was normal. However, on day three, the platelet count decreased rapidly. His blood haptoglobin level decreased, and schistocytes were identified on the peripheral blood smear. We suspected thrombotic microangiopathy and started the conventional treatment, comprising hemodialysis, blood transfusion, and antibiotic administration. ADAMTS-13 and genetic test results associated with atypical HUS were normal. Therefore, the patient was diagnosed with HUS caused by a sea anemone toxin. Conclusions HUS caused by a sea anemone toxin is rare, but it is a serious medical disease. Clinicians should consider HUS in patients with such clinical presentations, and they should make prompt treatment-related decisions.

Abstract
Constant research into the pharmaceutical properties of marine natural products has led to the discovery of many potentially active agents considered worthy of medical applications. Genus Conus, which approximately comprises 700 species, is currently under every researcher's interest because of the conopeptides in their crude venom. Conopeptides have a wide range of pharmacological classes and properties. This research focused on the crude venom of Conus striatus to assess its analgesic activity, mutagenicity, nephrotoxicity, and hepatotoxicity in mice. The crude venom was extracted from the conus snails and the protein concentration was determined using Bradford's method. The analgesic activity of the venom was determined using the hot-plate method and standard IFCC method was used to determine the alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Evaluation of mutagenicity was done using micronucleus assay and the nephrotoxicity of the venom was determined using Kidney Coefficient and serum creatinine concentration. The maximum tolerable dose (MTD) of the crude venom was found to be 75 ppm. The venom exhibited potent analgesic activity even higher than the positive control (Ibuprofen). Most of the analgesic drugs can usually impact damage in the liver and kidneys. However, AST and ALT results revealed that the venom has no adverse effects on the liver. Although the venom increased the incidence of micronucleated polychromatic erythrocytes, making it mutagenic, with MTD concentration's mutagenicity comparable to the positive control methyl methanesulfonate (MMS). The kidney coefficients, on the other hand, showed no significant difference between the treated groups and that of the untreated group. The serum creatinine also showed a concentration-dependent increase; with MTD treated mice got the highest creatinine concentration. However, MTD/2 and MTD/4 showed no significant difference in creatinine levels with respect to the untreated groups. Hence, the nephrotoxicity of the venom was only evident when used at higher concentration. The venom exhibited potent analgesic activity indicated that the C. striatus crude venom extract could have a potential therapeutic component as analgesic drugs that displayed no hepatic damage. This study also suggests that for this venom to be utilized for future medical applications, their usage must be regulated and properly monitored to avoid nephrotoxic effect.

Abstract
Marine toxins are known among several causes of toxin induced renal injury. Enzymatic mechanism by phospholipase A2 is responsible for acute kidney injury (AKI) in sea snake envenoming without any change in cardiac output and systemic vascular resistance. Cnidarian toxins form pores in the cell membrane with Ca influx storm resulting in cell death. Among plankton toxins domoic acid, palytoxin and maitotoxin cause renal injury by ion transport into the cell through ion channels resulting in renal cell swelling and lysis. Okadaic acid, calyculin A, microcystin LR and nodularin cause AKI by serine threonine phosphatase inhibition and hyperphosphorylation with increased activity of Ca2+/calmodulin - dependent protein kinase II, increased cytosolic Ca2+, reactive oxygen species, caspase and P53. Renal injury by plankons is mostly subclinical and requires sensitive biomarker for diagnosis. In this respect repeated consumption of plankton toxin contaminated seafood is a risk of developing chronic renal disease. The subject deserves more clinical study and scientific attention.

Abstract
A group of stable, water-soluble and membrane-bound proteins constitute the pore forming toxins (PFTs) in cnidarians. They interact with membranes to physically alter the membrane structure and permeability, resulting in the formation of pores. These lesions on the plasma membrane causes an imbalance of cellular ionic gradients, resulting in swelling of the cell and eventually its rupture. Of all cnidarian PFTs, actinoporins are by far the best studied subgroup with established knowledge of their molecular structure and their mode of pore-forming action. However, the current view of necrotic action by actinoporins may not be the only mechanism that induces cell death since there is increasing evidence showing that pore-forming toxins can induce either necrosis or apoptosis in a cell-type, receptor and dose-dependent manner. In this review, we focus on the response of the cellular immune system to the cnidarian pore-forming toxins and the signaling pathways that might be involved in these cellular responses. Since PFTs represent potential candidates for targeted toxin therapy for the treatment of numerous cancers, we also address the challenge to overcoming the immunogenicity of these toxins when used as therapeutics.

Abstract
Sea anemones contain a variety of interesting biologically active compounds, including some potent toxins. PLA2 from Bunodosoma caissarum, a sea anemone endemic in the Brazilian southern coast, has shown renal alterations on isolated kidney. The aim of this study was to evaluate the renal and vascular effects of B. caissarum crude extract (BcE) on isolated perfused kidney and arteriolar mesenteric bed, as well the involvement of prostaglandins and endothelin. BcE did not show any effect on arteriolar mesenteric bed, but increased perfusion pressure, renal vascular resistance, urinary flow, glomerular filtration rate and decreased the percentage of sodium tubular transport on isolated perfused kidney. Indomethacin blocked the renal effects induced by BcE and tezosentan only partially blocked these effects. These results demonstrate the effects of BcE on kidney in situ, suggesting the involvement of prostaglandins and endothelin.
