DefinitionThis section has been translated automatically.
Psoriatic form of chronic rheumatoid factor negative polyarthritic syndrome with DIP and PIP on hands and feet. Psoriatic arthritis is a destructive arthritis in 25% of cases and causes permanent disability. The arthritis can precede the skin symptoms by years and vice versa (see also psoriatic arthritis)
Occurrence/EpidemiologyThis section has been translated automatically.
- Psoriasis in the population: 1-3
- Arthritis psoriatica in patients with psoriasis: 5-15%.
- Arthritis psoriatica in the whole population: 0,1-0,2%
- Men and women fall ill equally frequently.

EtiopathogenesisThis section has been translated automatically.
ManifestationThis section has been translated automatically.
LocalizationThis section has been translated automatically.
Frequently infestation of the knee joint, then finger, ankle and toe joints; so-called "transverse infestation": Inclusion of the finger end joints as well as the toe joints or "infestation in the beam": Basic, middle and end joints affected (so-called dactylitis) with swelling of a finger or toe.
Clinical featuresThis section has been translated automatically.
- Preferential involvement of the finger end joints and nail changes
- Severe deformity with ossifications/articular stiffness and joint changes leading to mutilation.
- Symmetrical infestation of several joints (comparable to rheumatoid arthritis without rheumatoid factors)
- Infestation of one or less joints in the course of psoriasis (see below psoriasis vulgaris).
- Psoriatic arthritis with spinal manifestation.
LaboratoryThis section has been translated automatically.
General therapyThis section has been translated automatically.
- Cooperation with the rheumatologist. Protection of the joints during the attacks, endurance training between the attacks. In addition to movement exercises, movement baths (34 °C) and connective tissue massages, complementary ergotherapy (joint protection, self-help training, functional training).
Notice! No tablet without physiotherapy!
- As a decongestant measure during an acute episode, ice packs soothe the swelling, in other cases heat packs with fango or mud. In addition, short wave treatment, interference current treatment or ultrasound. Helpful are vitamin E in a dosage of 400-800 mg/day, additionally selenium and zinc substitution. The intake of eicosanoids, e.g. omega-3 fatty acids (Epamax), has proved extremely effective.
Remember! The drugs do not heal, but enable the patient to live with his or her disease as free of symptoms as possible!
External therapyThis section has been translated automatically.
- Non-steroidal anti-inflammatory drugs in ointment or gel base (e.g. Target Gel, Voltaren Emulgel).
- Glucocorticoids: Intra-articular glucocorticoid injections such as triamcinolone crystal suspension (e.g. Lederlon) under the usual aseptic conditions. For finger and toe joints, 1.5-3 mg intra-articularly, hand and ankle joints 10-20 mg intra-articularly are sufficient. Infiltration of the peritendinous tissue and painful tendon attachments.
Internal therapyThis section has been translated automatically.
Step-by-step therapy see below. Tab. 2 "Stepwise therapy for psoriasis arthropathica".
- Non-steroidal anti-inflammatory drugs: Indometacin (e.g. Amuno) 100-150 mg/day, diclofenac (e.g. Voltaren Drg.) 100-200 mg/day or ibuprofen (e.g. ibuprofen Klinge Drg.) 800-1200 mg/day p.o. Therapy to be used as needed or regularly.
- Glucocorticoid shock therapy: For intermittent relapse activity, glucocorticoid shock with prednisone equivalent (e.g. Decortin) 40 mg/day p.o., reduce by 5 mg every 3 days. Caveat. Gastric protection with e.g. Riopan gel.
Reminder. Every moderately severe or severe, clinically active psoriatic arthritis requires a basic therapy!
- Methotrexate: In severe cases methotrexate (e.g. Lantarel tbl.) 10-20 mg/week p.o. or i.m. (total dose max. 1.5 mg/week). (total dose max. 1.5 g!).
- Fumaric acid esters: Alternative trial with fumarates 1000-1200 mg/day p.o. (e.g. Fumaderm), gradual dosage. Improvement of symptoms after about 2-3 months.
- Combination therapy: The combination of MTX and fumarates has proven to be effective, especially in acute relapses. After about 3-4 months, after the acute attack has subsided, MTX can be discontinued and the Fumaderm therapy is continued. Close laboratory monitoring is a matter of course.
Notice. Glucocorticoids are not successful in all cases!
- Basic therapy: Peroral gold therapy (e.g. Auranofin) 6 mg/day p.o. If there is no improvement after 4-6 months, the dose may be increased to 9 mg/day p.o.
Alternative: Sulfasalazine (e.g. Azulfidine): Initial 500 mg/day p.o., weekly increase by 500 mg up to max. 2-3 times 1000 mg/day.
- Ciclosporin A (Sandimmun): Very effective and indicated in severe forms (dosage: 2.5 mg/kg bw/day p.o.).
- Etanercept (e.g. Enbrel): In refractory cases.
- Leflunomide (e.g. Arava): initially 100 mg/day for 3 days, then 20 mg/day. Comparable results exist with sulfasalazine with regard to efficacy and safety (TOPAS study). Therapeutic effect is expected after 4-6 weeks.
- Golimumab (Simponi): 1 time/month 50 mg s.c. (on the same day of each month), if necessary in combination with the individually required dose of MTX.
Upadacitinib is a selective and reversible JAK inhibitor. In human cell-based assays, upadacitinib preferentially inhibits JAK1 or JAK1/3 signaling pathways compared to other cytokine signaling pathways mediated via JAK2. Dosage 15 mg alternatively 30 mg/day.
Notice. Basic therapy must be avoided in pregnancy and infertility. Anticonception is indicated with all basic therapeutics, with cytotoxic substances also in men.
Operative therapieThis section has been translated automatically.
NaturopathyThis section has been translated automatically.
Lactovegetable diet: Naturopathically, the adherence to a lactovegetable diet with avoidance of animal meat and eggs (max. 2 portions / week) is recommended. Additionally polyunsaturated fatty acids, here e.g. in capsule form (e.g. Epamax®).
Excessive joint stress should be avoided in the stage of acute inflammation.
Harpagophyti radix: Psoriatic arthritis can be treated supportively with African devil's claw root(Harpagophyti radix), commercially available as e.g. Rivoltan®, Doloteffin®. Harpagophyti radix has anti-inflammatory and weak analgesic effects. A positive evaluation of the Commission E/ESCOP with assured effect in degenerative diseases of the musculoskeletal system, supportive in pain in the lumbar spine, digestive complaints and loss of appetite, is available. Side effect: Stimulates appetite and digestion.
Aternative: Salicis cortex, the willow bark, can also be used in a supportive way. Willow bark was already included in the German Pharmacopoeia (DAB 10) in 1991, confirmed in 1997 by the monograph of Commission E and ESCOP. The daily dose was increased to 240 mg (ESCOP monograph, 1997).
Supplementary: Frankincense resin, Boswella serrata H15 (see frankincense below), has anti-inflammatory effects by inhibiting the enzyme 5-lipoxygenase, which induces leukotriene synthesis. It is effective in diseases with elevated leukotriene levels such as bronchial asthma, rhinitis allergica, rheumatoid arthritis, lupus erythematosus, psoriasis, ulcerative colitis, Crohn's disease, multiple sclerosis.
A dosage of 2 x 450 mg is recommended.
