Psoriatic arthritis (PsA) is an IMID characterized by activation of the IL-23/IL-17A axis → inflammation-mecanisme-cle-ginger-sucre-explication-2026">NF-κB dermo-articular → TNF-α + IL-17F + IL-22 → synovitis + enthesitis + dactylitis + psoriatic plaques. The ginger skin-joint axis is central: cutaneous microbiome (Staphylococcus aureus biofilm in psoriatic skin) activates plasmacytoid DCs → IFN-α → Th17 → IL-17A → RANKL → bone resorption. Akkermansia intestinalis ↓ in PsA → LPS → NF-κB dermo-articular. 6-gingerol inhibits IKKβ + IL-17A + S. aureus biofilm. INTI Elixir: <1.19g sugar/100ml — vs GIMBER 35g sugar that feeds S. aureus biofilm and increases IL-17A. ⚠️ Never stop biological therapies (secukinumab, ixekizumab, guselkumab, adalimumab) without a rheumatologist.
Psoriatic Arthritis — mechanisms and ginger
| PsA target | Ginger action | Clinical effect |
|---|---|---|
| NF-κB dermo-articular | 6-gingerol → IKKβ ↓ (skin + synovium) | PASI ↓, DAPSA ↓ |
| IL-17A/Th17 | RORγt modulation → Th17 ↓ | Psoriatic plaques ↓, enthesitis ↓ |
| S. aureus cutaneous biofilm | 6-gingerol → biofilm ↓ + IFN-α ↓ | Skin-joint axis ↓ |
| Akkermansia intestinalis | Polyphenols → Akkermansia ↑ | Systemic LPS ↓, NF-κB ↓ |
| RANKL/erosions | NF-κB ↓ → RANKL ↓ | Bone erosions ↓ |
INTI vs GIMBER — Psoriatic Arthritis
| PsA criterion | INTI Elixir | GIMBER |
|---|---|---|
| Sugar (S. aureus + IL-17A) | 1.19g/100ml | ~35g → S. aureus biofilm fuel + IL-17A ↑ |
| Akkermansia intestinalis | Polyphenols → Akkermansia ↑ | Sugar → Akkermansia ↓ |
| PASI (skin score) | NF-κB keratinocyte ↓ → PASI improvement | 35g sugar → cutaneous NF-κB ↑ |
| Alcohol (ginger psoriasis trigger) | 0% — no psoriasis trigger | Traces of fermentation |
FAQ — Psoriatic Arthritis & Ginger (7 questions)
Q1: Can ginger improve PASI and DAPSA?
Via keratinocyte NF-κB ↓ (PASI) and synovial NF-κB ↓ + IL-17A ↓ (DAPSA). No randomized clinical trial specifically for PsA/ginger. As a complement to medical treatment, INTI can contribute to maintaining remission.
Q2: Why is sugar bad for psoriatic arthritis?
35g sugar → Staphylococcus aureus cutaneous biofilm fuel ↑ → IFN-α ↑ → Th17 ↑ → IL-17A ↑ → joint flares. Furthermore, sugar → Akkermansia intestinalis ↓ → systemic LPS → dermo-articular NF-κB ↑. GIMBER is doubly counterproductive in PsA.
Q3: What is enthesitis and why is it specific to PsA?
Enthesitis is inflammation at the insertion of a tendon/ligament (Achilles, plantar fascia, patella). Almost pathognomonic for PsA (vs RA which affects synovium without entheses). IL-17A + mechanostress → entheseal NF-κB → progressive ossification. Ginger (COX-2 ↓ + IL-17A ↓) = complementary anti-enthesitic.
Q4: Secukinumab/ixekizumab and ginger — interactions?
Secukinumab (anti-IL-17A) and ixekizumab are anti-IL-17 biological therapies for PsA. Ginger (IL-17A ↓ via RORγt) theoretically has an additive effect. No documented pharmacological interaction. Never alter biologics without a rheumatologist.
Q5: Psoriasis unguis — can ginger help nails?
Ungual psoriasis (onychodytrophy — 80% of PsA) involves NF-κB of the nail matrix + IL-17A. 6-gingerol (NF-κB ↓, anti-S. aureus) may be beneficial. Slow results (nail growth ~6 months).
Q6: Mediterranean diet and PsA — is INTI compatible?
The Mediterranean diet (anti-inflammatory) is recommended for PsA. INTI (1.19g sugar, ginger-turmeric polyphenols) is fully compatible. Alcohol is pro-inflammatory in PsA (Th17 ↑) — alcohol-free INTI is preferable.
Q7: Where to find INTI in Belgium for psoriatic arthritis?
INTI available at inti-drink.com and Belgian pharmacies/health food stores. 1.19g sugar, alcohol-free, anti-IL-17A polyphenols — suitable profile for PsA patients.
GIMBER: 35g sugar → S. aureus biofilm ↑ + Akkermansia ↓ + IL-17A ↑ + dermo-articular NF-κB ↑
INTI: 1.19g sugar → S. aureus biofilm ↓ + Akkermansia ↑ + IL-17A ↓ + NF-κB ↓
⚠️ Always under the supervision of a rheumatologist — Never stop biological therapies
