[INTRODUCTION - The joints have been secured from rheumatoid arthritis by diminution of biomechanical effeciency. This effect was analyzed and named articular protective phenomenon three decades ago. CASE REPORT - A case of bilateral rheumatoid arthritis associated with unilateral developmental abnormality hand and bronchial asthma in a 35 year old female patient is presented. Her left 2nd, 3rd, 4th and 5th metacarpal bones moreover her fingers had not evolved. The patient has been treated by antiasthmatic steroid drugs for five years. Rheumatoid disorders of the affected left hand were more severe, than the abnormality of the normal upper limb. Eight years later the most severe bony lesions (ankylosis and mutilation) appeared on this side, only. CONCLUSION - The patient's hand was not saved by inborn bone defect in rheumatoid arthritis. The absence of articular protective phenomenon can be explained by the undisturbed innervation of limb, the motility of hypotrophic carpus besides to steroid-induced suppression.]

[Heterotopic pregnancy]

SARLÓS Géza, VARGA Tamás, HEGEDŰS Géza

[INTRODUCTION - Simultaneous presence of intrauterine and extrauterine gestations is very rare. CASE REPORT - A 26 year old multiparous woman known to be 10 weeks pregnant presented with severe abdominal pain. Transabdominal sonography revealed a concomitant ectopic pregnancy with large amount of intraperitoneal fluid. Cardiac activities of both the intrauterine and the ectopic fetuses were clearly visible on abdominal ultrasound. Emergency laparoscopy confirmed intraabdominal hemorrhage and rupture of the left fallopian tube. The laparoscopic salpingectomy did not affect the ongoing intrauterine pregnancy. The woman subsequently delivered a healthy infant. CONCLUSION - Though heterotopic pregnancy especially without previous ovarian hyperstimulation is extremely rare. The confirmation of an intrauterine pregnancy does not exclude a co-existing ectopic pregnancy as well as in case of extrauterine pregnancy the simultaneous presence of an intrauterine pregnancy must be considered.]

[Rituximab therapy in rheumatoid arthritis]

SÜTŐ Gábor

[Rheumatoid arthritis is a chronic, lifelong disease that causes severe joint deformity, reduces quality of life, and, if not treated appopriately, leads to disability and substantial premature mortality. Its treatment is a multistep procedure, where different grades of treatment options follow each other. Besides traditional, diseasemodifying antirheumatic drugs (DMARDs) and biological therapies inhibiting TNF, a new therapautic option is the use of a chimeric antibody, rituximab, which inhibits B lymphocyte function. This drug is an effective and safe choice for those patients who have received various anti- TNF therapies or do not tolerate TNF inhibition.]

[The pathogenic and clinical significance of the RANK-RANKL-osteoprotegerin system in rheumatoid arthritis]

SZENTPÉTERY Ágnes, VÁNCSA Andrea, SZABÓ Zoltán, SZEKANECZ Zoltán

[Rheumatoid arthritis (RA) is characterised by increased local and generalised bone resorption, which manifests in the develoment of marginal erosions and generalised osteoporosis, respectively. An increasing number of data suggest that lymphocytes, proinflammatory cytokines and other mediators involved in inflammation contribute to arthritic bone resorption. Therefore, the term ‘osteoimmunology’ has also become widely used. In RA, Receptor Activator of Nuclear Factor kappa B (RANK) and its ligand (RANKL) play a crucial role in bone resorption. These proteins, which belong to the tumor necrosis factor a (TNF-a) receptor and TNF ligand superfamilies, respectively, activate osteoclasts while interacting with T cells, synovial fibroblasts and other cytokines (e.g. IL-1, IL-17), which results in bone resorption. Osteoprotegerin (OPG) is a decoy receptor that also belongs to the TNF receptor family and inhibits RANK-RANKL interactions. There is increased RANKL production and decreased OPG production in RA. The interaction of RANKL with IL-17 is particularly important. Regarding therapy, sulfasalazine, methotrexate and biological agents, especially TNF inhibitors suppress RANKL-mediated bone resorption and thus the development of joint erosions. RANKL-RANK interaction can be directly inhibited by recombinant OPG or anti-RANKL antibody (denosumab). Among these agents, denosumab gave promising results in experiments performed in animal models of arthritis. These were followed by a phase II human RA trial, which proved that denosumab decreased MRI erosion scores in RA.]

[Gene therapy as a treatment for rheumatoid arthritis]

JAMES M. Woods

[A clear understanding of the pathogenic events and/or environmental conditions that lead to the development of rheumatoid arthritis has not been accomplished. In recent years, some of the most capable therapies have targeted individual proteins, such as proinflammatory cytokines, which contribute to persistent inflammation. The success of these therapies in some patients underscores the importance of having a solid pathophysiologic knowledge of the mechanisms at play in the diseased joint. Targeting the joint therapeutically with proteins or other agents has presented many challenges in the treatment of rheumatoid arthritis. To circumvent these obstacles, the idea of providing transgenes to cells of the synovial lining was born. This use of gene therapy, as a delivery vehicle rather than replacement of a genetic deficit, has had many successes in preclinical animal studies. Preliminary results of the first Phase I clinical trial in humans suggests that an ex vivo approach can be safe and enable transgene expression. This review provides a consolidated overview of many of the successful gene therapy strategies undertaken for the treatment of animal models of arthritis. The focus is on: 1. joint targeting strategies, including discussion on the local and systemic approaches as well as the contralateral joint; 2. the applicability of viral vectors, including comparison of adenoviral, retroviral, adeno-associated, and herpes simplex viruses; 3. timing and dosage of treatment; and 4. targets and candidate proteins that have been examined, including targeting proinflammatory cytokines or the use of anti-inflammatory cytokines.]

[The importance of etanercept treatment in rheumatology]

GERGELY Péter, POÓR Gyula

[Rheumatoid arthritis, juvenile idiopathic arthritis, ankylosing spondylitis and psoriatic arthritis are inflammatory rheumatic conditions of unknown origin. Common characteristic features of these disorders include a relatively high prevalence, poorly understood pathogenesis and an unresolved treatment as well as a significant impact on mortality, morbidity and medical expenditures. The recognition of the central role of TNF-α in immune mediated inflammatory conditions, mainly in rheumatoid arthritis has led to the introduction of TNF-α blocking biological therapy into clinical rheumatology revolutionizing the management of these diseases. Etanercept is a human soluble TNF-α receptor attached to human IgG capable of effectively neutralizing TNF-α and lymphotoxin alpha. Since its introduction in 1998 as the first biological agent approved for RA, several clinical trials as well as everyday practice have proven its efficacy and safety. To date approximately 440 thousand patients, mostly with inflammatory rheumatic diseases have been treated with etanercept. In the present paper the pathophysiological role of TNF-α, the results of clinical trials of etanercept and its cost-effectivenes as well as issues regarding the use of etanercept in Hungary are reviewed.]
