Jaccoud’s Arthropathy

Jaccoud’s Arthropathy

A 58-year-old man presented with a 15-year history of systemic lupus erythematosus (SLE) that was characterized by polyarthritis, photosensitivity, malar rash, and pleuritis. Laboratory workup revealed antinuclear antibodies, anti–double-stranded DNA antibodies, anti-Ro (SS-A) antibodies, non–nephrotic-range proteinuria, and leukopenia. Testing for rheumatoid factor and anti-CCP antibodies was negative. Despite treatment with glucocorticoids, hydroxychloroquine, and azathioprine, hand deformities, including swan neck deformity, Z deformity of the thumb, and ulnar deviation of the fifth digit, developed over a 10-year period (Panel A and video). These deformities were reducible and are characteristic of Jaccoud’s arthropathy. Magnetic resonance imaging of the hands showed no erosions (Panel B). Although classically described in rheumatic fever, Jaccoud’s arthropathy has also been described in SLE and other diffuse connective-tissue diseases. In Jaccoud’s arthropathy, the deformities result mainly from soft-tissue abnormalities, such as laxity of ligaments, fibrosis of the capsule, and muscular imbalance, rather than from destruction of the bone of joints, as occurs in rheumatoid arthritis. The mainstay of the management of Jaccoud’s arthropathy includes physical therapy and the use of orthotic devices. Because this patient is a taxi driver, the hand deformities have been an important limitation to his capacity for work, despite physical therapy for muscle strengthening. Soft-tissue surgery for the correction of the hand deformities is under consideration but has not been performed.

Living with Lupus is often a battle not just against the illness itself, but also against the emotional weight of uncertainty, fatigue, and the toll of long-term medications. For one courageous woman, that battle began in 2013. Diagnosed after Lupus had already affected her joints and internal organs, she was quickly placed on medication that initially helped. But as time went on, her health declined again this time with more frequent flare-ups and increasingly difficult side effects. Like many others with chronic illness, she faced the crushing weight of hopelessness. Each day became harder than the last, and conventional treatments no longer offered the comfort they once did. But in March 2020, at her lowest point, she made a decision that changed everything.Out of desperation and with a healthy dose of skepticism she turned to NaturePath Herbal Clinic, hoping their natural Lupus treatment might offer at least some relief. What happened next went far beyond her expectations.After completing a six-month herbal program, her flare-ups stopped entirely. Her energy returned. The chronic pain that had defined her daily life began to fade. For the first time in years, she felt like herself again. Not just alive but truly living.Her story is not just one of healing; it’s one of resilience, open-mindedness, and the courage to try something new when all else fails. By sharing her journey, she hopes to offer something priceless to others living with Lupus: hope.This treatment has been a true breakthrough for her. If you’re searching for a safe, natural, and effective alternative, I genuinely recommend giving this a chance.”www.naturepathherbalclinic.com or email them at info@naturepathherbalclinic.com
