The presentation of haemochromatosis is typified by abdominal pain, arthralgia and fatigue or weakness. Arthropathy may be the major presenting feature. The detection of an osteoarthritis-like process involving the metacarpophalangeal (MCP) and wrist joints in middle aged men should signal the possibility of under lying haemochromatosis. Other joints such as the shoulder, hip,knee or ankle may be affected. However, the preferential involvement of the second and third MCP joints is striking and may provide the opportunity for early identification of iron overload disease. The "iron salut" can be an efficient screening tool for this MCP joint arthropathy but it is not well known by clinicians.

Hepcidin Is a Valuable Therapeutic Target for Colorectal Cancer.
Cancers (Basel)
December 2024
Department of Systems Medicine, University of Rome "Tor Vergata", 00133 Rome, Italy.
Colorectal cancer (CRC) is one of the most frequent neoplasms and a major cause of cancer death worldwide. Despite recent advances in treatment approaches, the prognosis of advanced CRC remains poor, thus indicating the necessity of more effective treatments for CRC patients. CRC cells produce high levels of hepcidin, a peptide hormone that binds to the membrane-bound ferroportin and promotes its internalization and degradation, thus sequestering iron into the cancer cells with the downstream effect of enhancing tumor growth.

Article Synopsis
- Hepcidin is a hormone linked to iron regulation, produced by colorectal cancer (CRC) cells, and this study investigates its potential as a prognostic biomarker in microsatellite stable (MSS) metastatic CRC (mCRC).
- The research found that mCRC patients with serum hepcidin levels over 40 ng/mL had a significantly lower one-year overall survival rate compared to those with lower levels, indicating a strong link between high hepcidin levels and poorer prognosis.
- Multivariate analysis confirmed that baseline serum hepcidin levels independently predict overall survival in MSS mCRC patients, suggesting it could be a useful marker for assessing treatment outcomes, warranting further research for validation.
Enhanced CRC Growth in Iron-Rich Environment, Facts and Speculations.
Int J Mol Sci
November 2024
Department of Experimental Medicine, University of Salento Centro Ecotekne, S.P.6, 73100 Lecce, Italy.
Article Synopsis
- Nutritional factors significantly contribute to the development of chronic conditions like obesity, type 2 diabetes, and certain cancers, involving both macronutrients and micronutrients.
- Macronutrients (proteins, carbohydrates, lipids) mainly provide energy and help synthesize biomolecules, while micronutrients (vitamins, minerals) support immune functions and enzymatic processes.
- The review specifically explores iron's role in tumor development, highlighting how iron-related proteins in tumors affect critical processes such as cell cycle, angiogenesis, and metastasis.
Unraveling the pathophysiology of restless legs syndrome from multimodal MRI techniques: A systematic review.
Sleep Med
January 2025
Clinical Neurophysiology Research Unit, Sleep Research Center, Oasi Research Institute-IRCCS, Troina, Italy; Department of Surgery and Medical-Surgical Specialties, University of Catania, Catania, Italy.
Article Synopsis
- - Restless Legs Syndrome (RLS) is a neurological disorder causing an uncontrollable urge to move the legs, primarily diagnosed through clinical features; this systematic review sought to analyze brain MRI data to better understand its underlying mechanisms.
- - The review examined 49 studies involving over 2,500 participants (RLS patients and healthy controls), focusing on various MRI techniques, and found significant alterations in brain structure and connectivity related to RLS, although there was notable variation in study methods.
- - The results highlight the importance of viewing RLS from a system-level perspective rather than attributing it to specific brain regions, suggesting a need for a more integrated understanding of the disorder within a broader biological framework.
Bone phenotyping of murine hemochromatosis models with deficiencies of Hjv, Alk2, or Alk3: The influence of sex and the bone compartment.

Osteopenia is frequently observed in patients with iron overload, especially in those with HFE-dependent hereditary hemochromatosis (HH). Interestingly, not all mouse models of HH show bone loss, suggesting that iron overload alone may not suffice to induce bone loss. In this study, the bone phenotypes of Hjv and hepatocyte-specific Alk2- and Alk3-deficient mice as additional mouse models of HH were investigated to further clarify, how high iron levels lead to bone loss and which signaling mechanisms are operational.
