Insights
Deferasirox is as effective as deferoxamine for reducing cardiac iron in beta-thalassemia patients. Lowering liver iron concentration improves the effectiveness of iron removal therapies.
Area of Science:
- Hematology
- Cardiology
- Pharmacology
Background:
- Beta-thalassemia patients often experience iron overload due to frequent blood transfusions.
- Cardiac iron accumulation is a major cause of morbidity and mortality in beta-thalassemia.
- Iron chelation therapy is essential for managing iron overload.
Purpose of the Study:
- To compare the efficacy of deferasirox (DFX) versus deferoxamine (DFO) in removing cardiac iron.
- To assess the impact of liver iron concentration (LIC) on iron removal efficacy.
Main Methods:
- The CORDELIA study involved patients with beta-thalassemia and cardiac iron.
- Cardiac iron was assessed, and patients received either DFX or DFO.
- Liver iron concentration (LIC) was measured.
Main Results:
- Deferasirox (DFX) was found to be non-inferior to deferoxamine (DFO) in reducing cardiac iron.
- The study confirmed that lower liver iron concentration (LIC) is associated with more effective cardiac iron removal.
- Both chelators demonstrated efficacy in iron reduction.
Conclusions:
- Deferasirox is a viable alternative to deferoxamine for cardiac iron chelation in beta-thalassemia.
- Optimizing liver iron levels may enhance the effectiveness of iron chelation therapy for cardiac iron reduction.
Abstract:
In this issue of Blood, the CORDELIA study presented by Pennell and colleagues shows that deferasirox (DFX; Exjade, Novartis) is not inferior to deferoxamine (DFO; Desferal, Novartis) for the removal of cardiac iron in β-thalassemia. CORDELIA also supports previous findings that efficacy of cardiac iron removal is better if liver iron concentration (LIC) is low.

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

01:23Cirrhosis I: Introduction
28
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

01:24Cirrhosis II: Pathophysiology
42
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to...

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
