GLOBAL DUPUYTREN’S DISEASE: AN OVERVIEW

Dupuytren’s disease, also known as Dupuytren’s contracture, is a connective tissue disorder that affects the hands. It causes the fingers to bend inward towards the palm in a contracture or flexion position. The condition is usually progressive and painless, but can eventually lead to loss of finger function if left untreated. While Dupuytren’s disease has historically been more common in Northern European populations, globalization and migration has increased its prevalence worldwide in recent decades. This article provides an overview of the current state of Dupuytren’s disease on a global scale.

EPIDEMIOLOGY

Studies show Dupuytren’s Disease most commonly affects Caucasian males over 50 years of age. However, its geographical distribution and epidemiology has been changing due to worldwide migration patterns. Traditionally, Northern European countries like Norway, Iceland, Ireland and Scotland reported the highest rates of Dupuytren’s at 10-30% of the population. Meanwhile, Asia and Africa saw very low prevalence rates below 1%.

Today, migration from Northern Europe to countries like Australia, New Zealand, Canada and the United States has increased rates there to 5-10% in Caucasian males. Likewise, as Northern European populations emigrate to the Middle East, Southeast Asia and other regions, Dupuytren’s prevalence is rising in expatriate communities. For instance, multiple studies from the Middle East note increased Dupuytren’s among European residents compared to native populations.

GENETIC AND ENVIRONMENTAL FACTORS

While genetics plays an undisputed role, environmental exposures also influence Dupuytren’s risk. People with a family history of the condition have 3-10 times higher odds of developing it compared to the general population. Specific gene variants on chromosomes 2p, 7q, 15q and 16q have been linked to Dupuytren’s in Genome Wide Association Studies.

In terms of environment, manual labor jobs entailing vibration exposure from power tools increase risk by 2-3 times. Other risk factors include cigarette smoking, diabetes mellitus, obesity, alcoholism and epilepsy. Northern European populations possessed genetic adaptations to harsh environments which may predispose to Dupuytren’s and limit its prevalence in tropical regions prior to globalization.

TREATMENT AND MANAGEMENT

Conservative nonsurgical interventions for mild Dupuytren’s contractures include massage, stretching, splinting, steroid injections and radiation therapy. For severe, functionally impairing contractures, surgical fasciectomy remains the mainstay treatment to release fibrotic tissue and extend the fingers. Newer minimally invasive procedures like needle fasciotomy are also gaining popularity.

Post-surgical rehabilitation focuses on scar management, range of motion exercises and splinting to maintain joint flexibility. Contracture recurrence after surgery remains common at 30-70% depending on individual risk factors. Multiple operations may be required in some refractory cases. Clinical management of Dupuytren’s poses unique global challenges reflecting diverse cultural, economic and resource contexts.

IMPLICATIONS FOR GLOBAL HEALTH

As more populations experience rising Dupuytren’s rates due to migration and environmental exposures, its associated disability and healthcare costs will grow worldwide. This necessitates global efforts to raise awareness, standardized assessment methods, optimal surgical techniques, and rehabilitation protocols tailored to local needs. Telemedicine could help expand access to specialist care in remote areas. International collaborative research is also needed to elucidate genetic-environmental interactions and develop new nonsurgical therapies, especially for underserved groups.

Overall, Dupuytren’s disease exemplifies how a condition originally confined to specific ethnicities can become a broader global health issue in our modern interconnected world. A coordinated multinational approach will be important to address the evolving epidemiology and rising disease burden of Dupuytren’s contracture on a worldwide scale.
