Brief Summary:
Erosive hand osteoarthritis (EHOA) is a difficult-to-treat subtype of HOA characterized by local and systemic low-grade inflammation as well as by high level of pain and of disability.
Auricular transcutaneous vagus nerve stimulation (tVNS) is a promising therapeutic strategy that may reduce inflammation and pain level.
ESTIVAL is a 12 weeks randomized sham-controlled trial investigating the symptomatic efficacy and safety of tVNS in patients with symptomatic and inflammatory EHOA.
tVNS will be performed using a transcutaneous electrical nerve stimulation (TENS) device connected to an auricular electrode stimulating the cutaneous area of the left ear innervated by the auricular ascendant branch of the vagus nerve.
The active and sham device's will display similar appearance but the sham one will not give electric signal.

Detailed Description:
Symptomatic hand osteoarthritis (HOA) affects 8-16% of the general population above 50 years and involves interphalangeal (IP) joints. HOA symptoms include pain, stiffness and are responsible for disability and substantial burden. Erosive HOA (EHOA) (10% prevalence among symptomatic HOA from the general population and 40-50% prevalence in tertiary centers) is the most severe HOA phenotype characterized by inflammatory flares, more IP joint destruction, pain, soft swelling joints (ie, synovitis), and more disability (similar to rheumatoid arthritis (RA)) than its non-erosive counterpart.
Current symptomatic pharmacological treatments of HOA or EHOA have a poor efficacy on pain (ie, paracetamol) or safety issues (ie, non-steroidal anti-inflammatory drugs (NSAIDs)) in this aging population with frequent comorbidities. Systemic and joint inflammation contribute to EHOA but 4 studies using TNF inhibitors, 2 using hydroxychloroquine, 1 using methotrexate and 1 using a new anti-IL1α/β failed to show any efficacy on pain in HOA or in EHOA. Therefore, innovative therapeutic approaches are awaited.
Stimulation of the vagus nerve (VNS), belonging to parasympathetic system, dampens pro-inflammatory cytokines production by splenic macrophages, through to the binding of acetylcholine neurotransmitter to α7nicotinic receptor on macrophages: this is the cholinergic anti-inflammatory pathway (CAP). VN stimulation (VNS) by cervical implantable device activating CAP has given promising results in refractory RA patients. Beyond its anti-inflammatory effects, VNS is analgesic in chronic pain disorders (headache, fibromyalgia). However, the use of such implantable device is limited by the need of cervical surgery and subsequent potential side effects.
Besides implantable devices, VNS may be also performed using transcutaneous VNS (tVNS) of the ascendant auricular branch of the VN that selectively innervates the cutaneous zone of cymba conchae at the left ear. Auricular tVNS avoids invasive neurosurgery and its potential side effects and is less expensive than implantable VNS, making it an attractive candidate for neurostimulation. Auricular tVNS has given positive results in chronic migraine and is currently tested in RA, Crohn's disease, widespread pain, irritable bowel syndrome and musculoskeletal pain related to systemic lupus.
We hypothesize that auricular tVNS using a transcutaneous electrical nerve stimulation (TENS) device could be a novel, simple and well-tolerated analgesic and anti-inflammatory treatment of symptomatic (i.e., painful) and inflammatory EHOA.
ESTIVAL is a 12 weeks randomized sham-controlled trial investigating the symptomatic efficacy and the safety of tVNS in patients with symptomatic and inflammatory EHOA.
tVNS will be performed using an active or sham transcutaneous electrical nerve stimulation (TENS) device connected to an auricular electrode stimulating the cutaneous area of the left ear innervated by the auricular ascendant branch of the vagus nerve.
Exploratory and ancillary studies will include i) changes of serum biomarkers of inflammation and of cartilage degradation that will be assess at inclusion and at week 12 ii) hand MRI at W0 and W12 of the most symptomatic joint at inclusion for HOAMRIS socring at W0 and W12 for the center of Saint Antoine.
A phone call at D7± 3 days by the clinical research technician or the clinical nurse or the doctor who has performed the education during the D0 visit to check the proper use of the device.
