Insights
New non-invasive theranostic capsules offer a potential cure for obscure gastrointestinal bleeding. These oral capsules diagnose and treat bleeding, addressing a critical unmet need in gastroenterology.
Area of Science:
- Gastroenterology
- Biomedical Engineering
- Nanotechnology
Background:
- Obscure gastrointestinal (GI) bleeding presents a diagnostic challenge, often requiring invasive procedures.
- Current diagnostic methods like endoscopy and angiography are invasive, while video capsule endoscopy (VCE) lacks therapeutic capabilities.
- There is a significant need for non-invasive treatments for obscure GI bleeding.
Purpose of the Study:
- To develop and propose a novel non-invasive theranostic capsule for diagnosing and treating obscure GI bleeding.
- To create an orally administered capsule that combines diagnostic and therapeutic functions.
Main Methods:
- Design of a theranostic capsule incorporating endothelin for targeting, thrombin-fibrinogen or fibrin for treatment, and fluorescein dye for diagnosis.
- Oral administration of the capsule for a non-invasive approach.
Main Results:
- The proposed theranostic capsule offers a simple, non-invasive method for diagnosing obscure GI bleeding.
- The capsule has the potential to provide simultaneous diagnosis and treatment of GI bleeding.
- This approach aims to mitigate complications associated with invasive procedures.
Conclusions:
- Non-invasive theranostic capsules represent a promising advancement in managing obscure GI bleeding.
- This technology could revolutionize the diagnosis and treatment of GI bleeding disorders.
- Further research and clinical validation are warranted for this innovative theranostic approach.
Abstract:
Obscure gastrointestinal (GI) bleeding is identified as persistent or repeated bleeding from the gastrointestinal tract which could not be defined by conventional gastrointestinal endoscopy and radiological examinations. These GI bleedings are assessed through invasive diagnostic and treatment methods including enteroscopy, angiography and endoscopy. In addition, video capsule endoscopy (VCE) is a non-invasive method used to determine the location of the bleeding, however, this does not provide any treatment. Despite of these successful but invasive methods, an effective non-invasive treatment is desperately needed. Herein, we prepare non-invasive theranostic capsules to cure obscure GI bleeding. An effective theranostic capsule containing endothelin as the targeting agent, thrombin-fibrinogen or fibrin as the treating agent, and fluorescein dye as the diagnostic tool is suggested. These theranostic capsules can be administered orally in a simple and non-invasive manner without a risk of complication. By using these novel capsules, one can diagnose obscure GI bleeding with having a possibility of curing.
