Insights
Arthritis is a common and early symptom of hereditary hemochromatosis, often leading to severe joint damage and the need for joint replacement surgery. This study highlights the significant disease burden of arthritis in these patients.
Area of Science:
- Rheumatology
- Genetics
- Internal Medicine
Background:
- Hereditary hemochromatosis is a genetic disorder characterized by excessive iron absorption and storage.
- Iron overload can affect various organs, including joints, leading to arthritis.
- The full spectrum of joint involvement in hereditary hemochromatosis is not well-defined.
Purpose of the Study:
- To determine the prevalence, clinical presentation, and disease burden of arthritis in patients with hereditary hemochromatosis.
- To investigate the association between specific factors and the severity of joint disease.
Main Methods:
- Cross-sectional observational study of 199 patients with hereditary hemochromatosis.
- Assessment of joint pain, rheumatologic investigation, and radiographic scoring for joint damage.
- Recording of demographic data, genotype, organ involvement, and history of joint replacement surgery.
Main Results:
- Arthritis symptoms, particularly joint pain, were reported by 72.4% of patients, often preceding the hemochromatosis diagnosis.
- Radiographic findings included frequent joint space narrowing, osteophytes, and chondrocalcinosis.
- 16.1% of patients underwent joint replacement surgery due to severe osteoarthritis, with female sex and specific joint involvement being risk factors for early failure.
Conclusions:
- Arthritis is a frequent, early-onset, and severe manifestation of hereditary hemochromatosis.
- The joint disease is not limited to specific joints and can result in significant damage requiring surgical intervention.
- Understanding these arthritis patterns is crucial for managing the overall disease burden in hereditary hemochromatosis.
Objective:
To determine the prevalence, clinical picture, and disease burden of arthritis in patients with hereditary hemochromatosis.
Methods:
In this cross-sectional observational study of 199 patients with hemochromatosis and iron overload, demographic and disease-specific variables, genotype, and organ involvement were recorded. The prevalence, intensity, and localization of joint pain were assessed, and a complete rheumatologic investigation was performed. Radiographs of the hands, knees, and ankles were scored for joint space narrowing, erosions, osteophytes, and chondrocalcinosis. In addition, the number and type of joint replacement surgeries were recorded.
Results:
Joint pain was reported by 72.4% of the patients. Their mean ± SD age at the time of the initial joint symptoms was 45.8 ± 13.2 years. If joint pain was present, it preceded the diagnosis of hemochromatosis by a mean ± SD of 9.0 ± 10.7 years. Bony enlargement was observed in 65.8% of the patients, whereas synovitis was less common (13.6%). Joint space narrowing and osteophytes as well as chondrocalcinosis of the wrist and knee joints were frequent radiographic features of hemochromatosis. Joint replacement surgery was common, with 32 patients (16.1%) undergoing total joint replacement surgery due to severe OA. The mean ± SD age of these patients was 58.3 ± 10.4 years at time of joint replacement surgery. Female sex, metacarpophalangeal joint involvement, and the presence of chondrocalcinosis were associated with a higher risk of early joint failure (i.e., the need for joint replacement surgery).
Conclusion:
Arthritis is a frequent, early, and severe symptom of hemochromatosis. Disease is not confined to involvement of the metacarpophalangeal joints and often leads to severe damage requiring the replacement of joints.

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
