Lonomia obliqua Walker (Lepidoptera: Saturniidae): hemostasis implications

1Universidade Feevale, Caxias do Sul, RS, Brazil.
Summary
Accidents caused by Lonomia obliqua caterpillars in Brazil can lead to severe health issues, including bleeding and kidney failure. Early diagnosis and treatment with antivenom are crucial for patient survival.
Area of Science:
- Toxicology
- Entomology
- Clinical Medicine
Background:
- Lonomia obliqua caterpillars in southern Brazil cause envenomation through skin contact.
- Their gregarious behavior and daytime congregation on tree trunks increase accident risk.
- The caterpillar's venom contains proteins that disrupt hemostasis.
Purpose of the Study:
- To describe the clinical manifestations and diagnosis of Lonomia obliqua envenomation.
- To highlight the importance of prompt medical intervention.
Main Methods:
- Diagnosis relies on medical history, clinical signs, erythrocyte counts, and coagulation parameters.
- No specific laboratory diagnostic tests were previously described.
Main Results:
- Envenomation can cause hemorrhagic syndrome, consumption coagulopathy, intravascular hemolysis, and acute renal failure.
- Poisoning can be severe and potentially fatal.
Conclusions:
- Early diagnosis based on clinical and coagulation data is essential.
- Treatment involves supportive care and specific hyperimmune antivenom administration.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Extrinsic and Intrinsic Pathways of Hemostasis
15.5K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Disorders of Hemostasis
2.8K
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Introduction to Hemostasis
17.2K
Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
