Predictive risk factors of serious infections in patients with rheumatoid arthritis treated with abatacept in common practice: results from the Orencia and Rheumatoid Arthritis (ORA) registry.

OBJECTIVES: Little data are available regarding the rate and predicting factors of serious infections in patients with rheumatoid arthritis (RA) treated with abatacept (ABA) in daily practice. We therefore addressed this issue using real-life data from the Orencia and Rheumatoid Arthritis (ORA) registry. METHODS: ORA is an independent 5-year prospective registry promoted by the French Society of Rheumatology that includes patients with RA treated with ABA. At baseline, 3 months, 6 months and every 6 months or at disease relapse, during 5 years, standardised information is prospectively collected by trained clinical nurses. A serious infection was defined as an infection occurring during treatment with ABA or during the 3 months following withdrawal of ABA without any initiation of a new biologic and requiring hospitalisation and/or intravenous antibiotics and/or resulting in death. RESULTS: Baseline characteristics and comorbidities: among the 976 patients included with a follow-up of at least 3 months (total follow-up of 1903 patient-years), 78 serious infections occurred in 69 patients (4.1/100 patient-years). Predicting factors of serious infections: on univariate analysis, an older age, history of previous serious or recurrent infections, diabetes and a lower number of previous anti-tumour necrosis factor were associated with a higher risk of serious infections. On multivariate analysis, only age (HR per 10-year increase 1.44, 95% CI 1.17 to 1.76, p=0.001) and history of previous serious or recurrent infections (HR 1.94, 95% CI 1.18 to 3.20, p=0.009) were significantly associated with a higher risk of serious infections. CONCLUSIONS: In common practice, patients treated with ABA had more comorbidities than in clinical trials and serious infections were slightly more frequently observed. In the ORA registry, predictive risk factors of serious infections include age and history of serious infections.

Usefulness of monitoring of B cell depletion in rituximab-treated rheumatoid arthritis patients in order to predict clinical relapse: a prospective observational study.

Our objective was to evaluate the contribution of monitoring B cell subset depletion after rituximab in patients with rheumatoid arthritis (RA) in order to guide reintroduction to forestall relapse. This prospective, monocentre study included all RA patients receiving two 1-g rituximab infusions at a 15-day interval. The patients were followed clinically and biologically every 2 months until rituximab reintroduction. The physician was blinded to lymphocyte-typing results to diagnose relapse and, hence, retreatment. Among the 39 patients included between March 2010 and December 2011 and followed until April 2013, seven received two rituximab cycles, yielding a total of 46 cycles for analysis. After the two rituximab cycles, the total number of CD19(+) B cells decreased significantly (0·155 versus 0·0002 G/l, P < 0·0001), with complete depletions in all patients of CD19(+) CD38(++) CD24(++) (transitional) (P < 0·0001) and CD19(+) CD27(+) (memory) B lymphocytes. A significant majority of patients relapsed within the 4 months following repopulation of total B (P = 0·036), B transitional (P = 0·007) and B memory (P = 0·01) lymphocytes. CD19(+) B lymphocyte repopulation preceded clinical RA relapse and enabled its prediction 4 months in advance. Hence, monitoring of CD19(+) B lymphocytes could serve as a tool to predict those relapses.

Fcγ receptor type IIIA polymorphism influences treatment outcomes in patients with rheumatoid arthritis treated with rituximab.

OBJECTIVE: To assess the association between a single nucleotide polymorphism in the gene of FCGR3A and the response to treatment with rituximab (RTX) in rheumatoid arthritis (RA). METHODS: SMART is a randomised open trial assessing two strategies of re-treatment in patients responding to 1 g infusion of RTX with methotrexate on days 1 and 15 after failure, intolerance or contraindication to tumour necrosis factor (TNF) blockers. Among the 224 patients included, 111 could be genotyped and were included in an ancillary study of SMART. Univariate and multivariate analyses adjusted on disease activity score on 28 joints were performed to assess whether FCGR3A-158V/F polymorphism was associated with European League Against Rheumatism response at week 24. RESULTS: Among the 111 patients, 90 (81%) were responders of whom 30 (27%) were good responders. V allele carriage was significantly associated with a higher response rate (91% of responders vs 70%, OR 4.6 (95% CI 1.5 to 13.6), p=0.006). These results were also confirmed in rheumatoid factor-positive patients (93% vs 74%, p=0.025). In multivariate analysis, V allele carriage was independently associated with response to RTX (OR 3.8 (95% CI 1.2 to 11.7), p=0.023). CONCLUSION: The 158V/F polymorphism of FCGR3A seems to influence the response to RTX in patients with RA after failure, intolerance or contraindication to TNF blockers.

Positivity for anti-cyclic citrullinated peptide is associated with a better response to abatacept: data from the 'Orencia and Rheumatoid Arthritis' registry.

OBJECTIVES: Very limited data are available regarding the efficacy of abatacept (ABA) in real life. The aims of this study were to determine the efficacy of ABA in rheumatoid arthritis and predicting factors of efficacy in common practice. METHODS: The Orencia and Rheumatoid Arthritis" (ORA) prospective registry, promoted by the French Society of Rheumatology, has included 1003 patients with RA. RESULTS: 773 patients had already fulfilled the 6-month follow-up visit. Only 21.3% of patients would have fulfilled inclusion criteria used in pivotal controlled trials. The European League Against Rheumatism (EULAR) response, was observed in 330 (59.1%) of the 558 assessed patients (good response: 20.4%, moderate response: 38.7%) and was similar in patients who did and in patients who did not fulfill inclusion criteria of controlled trials. Among EULAR responders, initial 28-joint disease activity score (5.4 (4.7-6.5) in responders vs 4.9 (4.0-6.0) in non responders, p< 0.0001), the proportion of rheumatoid factor (75.6% vs 66.7%, p= 0.03) and the proportion of anti-cyclic citrullinated peptide antibody (anti-CCP)-positivity (75.9% vs 62.2%, p= 0.001) were significantly higher. In multivariate analysis adjusted on initial 28-joint disease activity score and CRP, anti-CCP positivity was associated with EULAR response (OR=1.9;95% CI=1.2 to 2.9, p=0.007), but not rheumatoid factor (OR=1.0;95% CI=0.6 to 1.6, p=0.9). Anti-CCP positivity was also significantly associated with a higher ABA retention rate at 6 months. CONCLUSIONS: Real life efficacy of ABA in the ORA registry was similar as that reported in clinical trials. Anti-CCP positivity was associated with a better response to ABA, independently from disease activity.

Risk factors for severe infections in patients with rheumatoid arthritis treated with rituximab in the autoimmunity and rituximab registry.

OBJECTIVE: The risk of severe infection is a crucial factor in the assessment of the short-term risk:benefit ratio of biologic drugs in rheumatoid arthritis (RA). There is no increase in severe infections in RA patients treated with rituximab (RTX) in controlled trials, but this has not yet been assessed in daily practice. We undertook this study to investigate the occurrence of and risk factors for severe infections in off-trial patients using data from the AutoImmunity and Rituximab (AIR) registry. METHODS: The AIR registry was set up by the French Society of Rheumatology. The charts of patients with severe infections were reviewed. RESULTS: Of the enrolled patients, 1,303 had at least 1 followup visit at 3 months or later, with a mean ± SD followup period of 1.2 ± 0.8 years (1,629 patient-years). Eighty-two severe infections occurred in 78 patients (5.0 severe infections per 100 patient-years), half of them in the 3 months following the last RTX infusion. Multivariate analysis showed that chronic lung disease and/or cardiac insufficiency (odds ratio 3.0 [95% confidence interval 1.3-7.3], P = 0.01), extraarticular involvement (odds ratio 2.9 [95% confidence interval 1.3-6.7], P = 0.009), and low IgG level (<6 gm/liter) before initiation of RTX treatment (odds ratio 4.9 [95% confidence interval 1.6-15.2], P = 0.005) were significantly associated with increased risk of a severe infection. CONCLUSION: The rate of severe infections in current practice is similar to that reported in clinical trials. The risk factors for severe infections include chronic lung and/or cardiac disease, extraarticular involvement, and low IgG before RTX treatment. This suggests that serum IgG should be checked and the risk:benefit ratio of RTX discussed for patients found to have low levels of IgG.

Interleukin-1 receptor antagonist (anakinra) treatment in patients with systemic-onset juvenile idiopathic arthritis or adult onset Still disease: preliminary experience in France.

BACKGROUND: Anakinra treatment has been reported to be effective in some patients with systemic-onset juvenile idiopathic arthritis (SoJIA) or adult-onset Still disease (AoSD). OBJECTIVES: To assess the efficacy and the safety of anakinra treatment in SoJIA and AoSD. METHODS: SoJIA and AoSD patients were treated with anakinra (1-2 mg/kg/day in children, 100 mg/day in adults); we analysed its effect on fever, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, numbers of swollen and tender joints, the assessment of disease activity (by physician and parent/patient) and pain (by parent/patient), and American College of Rheumatology (ACR) pediatric core set criteria for JIA activity. RESULTS: A total of 35 patients were included, 20 with SoJIA and 15 with AoSD. Their mean age (range) at the onset of treatment was 12.4 (3-23) and 38.1 (22-62) years, respectively; disease duration was 7.0 (1-16) and 7.8 (2-27) years, respectively. Active arthritis was present in all cases but one. Of the 20 SoJIA patients, 5 achieved ACR 50% improvement in symptoms (ACR50) response criteria at 6 months. Steroid dose had been decreased by 15% to 78% in 10 cases. A total of 11 of the 15 AoSD patients achieved at least a 50% improvement for all disease markers (mean follow-up: 17.5 (11-27) months). Steroids had been stopped in two cases and the dose was decreased by 45% to 95% in 12 patients. Two patients stopped anakinra due to severe skin reaction, and two patients due to infection: one visceral leishmaniasis and one varicella. CONCLUSION: Anakinra was effective in most AoSD patients, but less than half SoJIA patients achieved a marked and sustained improvement.

Contribution of PTPN22 1858T, TNFRII 196R and HLA-shared epitope alleles with rheumatoid factor and anti-citrullinated protein antibodies to very early rheumatoid arthritis diagnosis.

OBJECTIVES: To evaluate the predictive value of TNFRII 196R, PTPN22 1858T and HLA-shared epitope (SE) alleles, RFs and anti-citrullinated protein antibodies (ACPAs) for RA diagnosis in a cohort of patients with very early arthritis. METHODS: We followed up 284 patients who had swelling of at least two joints that had persisted for longer than 4 weeks but had been evolving for <6 months. At 2 yrs, patients were classified as having RA or non-RA rheumatic diseases according to the ACR criteria. Patients were genotyped with respect to TNFRII 196M/R and PTPN22 1858C/T polymorphisms and HLA-SE. The presence of IgA, IgG and IgM RF isotypes and ACPA was sought in sera collected at disease onset. RESULTS: HLA-SE alleles alone, concomitant presence of TNFRII 196R and PTPN22 1858T alleles, IgA, IgG and IgM RF alone and ACPA were found to be significantly associated with RA diagnosis. Using logistic regression analysis, the concomitant presence of RF and ACPA at disease onset was the best association to predict RA diagnosis. In patients (n = 34) who did not fulfil the ACR criteria for RA at inclusion but who progressed to ACR positivity, the study of the genetic risk markers did not contribute to predict RA diagnosis at 2 yrs. CONCLUSIONS: PTPN22 1858T, TNFRII 196R and HLA-SE alleles do not improve the predictive value of RF and ACPA for RA diagnosis in our cohort, and do not contribute to an earlier diagnosis in undifferentiated patients initially negative for RF and ACPA.

[Cutaneous vasculitis with necrotic ulcers in rheumatoid arthritis: treatment with anti-TNFalpha]. / Vasculite avec ulcérations cutanées au cours de la polyarthrite rhumatoïde: traitement par anti TNFalpha.

INTRODUCTION: Anti-TNFalpha has occasionally been used in the treatment of recalcitrant forms of systemic vasculitis such as Behçet's disease, Wegener's granulomatosis and Churg-Strauss syndrome. We report on the outcome of treatment in rheumatoid arthritis patients with cutaneous vasculitis lesions on anti-TNFalpha. OBSERVATIONS: Two patients with rheumatoid arthritis present for several years had necrotic ulcers of the lower limbs due to cutaneous vasculitis. After the failure of various immunosuppressive drugs (cyclophosphamide, azathioprine, methotrexate), the two patients were treated with anti-TNFalpha: infliximab in the first case and adalimumab in the second. Cutaneous ulcers healed within two to four months of the start of anti-TNFalpha treatment. Despite ongoing anti-TNFalpha treatment, these cutaneous ulcers relapsed four to six months after complete healing. CONCLUSION: Initially spectacular healing of cutaneous vasculitis ulcers under anti-TNF alpha treatment followed by relapse after several months of treatment is suggestive of an escape mechanism.

Spinal abscess and spondylitis due to actinomycosis.

STUDY DESIGN: Report of a rare case of spinal actinomycosis in a young immunocompetent woman. OBJECTIVE: To show the difficulties in diagnosing spinal actinomycosis. SUMMARY OF BACKGROUND DATA: Spinal actinomycosis is rare and usually occurs as a result of a contiguous (abdominal, pelvic, or thoracic) spread of the infection. This localization represents less than 5% of the infectious sites and was mainly, before the penicillin era, a postmortem discovery. METHODS: A case is reported of a 34-year-old Algerian woman who had fever, persistent cough, right-side thoracic pain, and progressive severe back pain. Radiographs, computed tomographic scan, and magnetic resonance imaging demonstrated lytic areas on the vertebral bodies of T11 and T12 and a paravertebral mass, without disk involvement. A surgical biopsy of T12 and the paravertebral abscess was performed. RESULTS: Presence of characteristic sulfur granules and gram-positive filamentous bacteria in surgical biopsy tissues and isolation of Actinobacillus actinomycetemcomitans in cultures led to the diagnosis of vertebral actinomycosis. The patient was virtually free of pain and fever after a 3-month regimen of ofloxacin and rifampicin (Rifadine, Marion-Merell, France) and was without recurrence after 18 months of follow-up. CONCLUSIONS: Actinomycosis of the spine, caused by the spread of a paraspinal abscess, is extremely rare. The previously poor prognosis has been transformed by antibiotics.

Anti-TNF-alpha-induced systemic lupus syndrome.

Anti-TNF-alpha therapies are promising new strategies in the treatment of rheumatoid arthritis (RA). Despite good clinical efficacy and tolerance, the possible occurrence of drug-induced autoimmune disorders remains a matter of concern. Induction of antinuclear (ANA) and anti-DNA antibodies is observed in some patients treated with TNF-alpha inhibitors (anti- TNF-alpha antibodies) or soluble TNF-alpha receptor. Of concern is the possibility of induction of true lupus erythematosus by TNF blockers. Few cases without major organ involvement were reported to be associated with infliximab treatment that resolved after anti-TNF discontinuation. Only four cases have been described with the use of etanercept. We report a new case of infliximab-induced lupus syndrome and two new cases of etanercept-induced lupus syndrome in three patients with RA, all of whom had previous isolated positive ANA.

Antibodies and vascular involvement in inflammatory joint disease: clinical relevance.

The vascular endothelium is a common target of inflammatory joint disease. Autoimmune diseases including rheumatoid arthritis, systemic lupus erythematosus, and Sjögren's syndrome can be responsible for a spectrum of vascular disorders that encompasses vasculitis, thrombosis and/or atheroma associated with the antiphospholipid syndrome, and vascular damage caused by cryoglobulin deposition. These mechanisms can coexist, particularly in lupus patients. Joint disease is sometimes the presenting manifestation in primary vasculitis. Autoantibodies are detectable in most patients with vascular involvement and inflammatory joint disease. They are not merely markers for vascular involvement: in vitro and in vivo data suggest that some autoantibodies may contribute to the genesis of endothelial lesions, together with other factors. For instance, evidence of pathogenic effects has been found for antineutrophil cytoplasmic antibody (ANCA), most notably with antimyeloperoxidase or antiproteinase-3 specificity, in small-vessel vasculitides (Wegener's granulomatosis, Churg-Strauss syndrome, and microscopic polyangiitis); for immune complexes, particularly those containing cryoglobulins, in vasculitides secondary to CTDs; and for circulating anticoagulant and anticardiolipin antibodies, above all anti-beta2-glycoprotein I, in antiphospholipid syndrome. Antibodies to annexin V, modified lipoproteins, and endothelial cells may be of interest; their clinical relevance is unclear, however, and no standardized assays are available, so thatthese antibodies are not looked for in everyday practice. When deciding which antibody tests should be performed in a given patient, the circumstances surrounding the onset of the vasculopathy should be borne in mind. In patients with previous CTD, the tests are selected based on the diagnosis. In contrast, in a patient with no previous diagnosis, a vasculopathy can be either primary or secondary to undiagnosed CTD or to antiphospholipid syndrome: consequently, a broader array of tests is needed in this situation.

A shock associated with adult-onset Still's disease.

Only two cases of adult-onset Still's disease associated with shock have been previously described. We report a case of shock in a man with adult-onset Still's disease and discuss the relationship between the two processes by assessing tumor necrosis factor-alpha, procalcitonin and interleukin-6 concentrations.

Prospective X-ray densitometry and ultrasonography study of the hand bones of patients with rheumatoid arthritis of recent onset.

OBJECTIVE: Bone demineralization observed in early rheumatoid arthritis is not easily measured. To measure bone loss and to discriminate between rheumatoid arthritis and other rheumatic diseases, we used two methods: dual-energy X-ray absorptiometry and ultrasonography. METHODS: From a population-based recruitment, 32 patients with early peripheral polyarthritis (median disease duration: 4 months) were studied. Clinical, laboratory, functional, hand-bone assessments were made at the entry an at months 6 and 12. Bone X-ray densitometry measurements were made on 16 areas of the hand. Speed of sound was measured across the proximal phalanges of the four fingers. X-rays of both hands were scored according to the modified Sharp's score. At 12 months, patients were classified as rheumatoid arthritis (N = 15; 9 F) or as other rheumatic diseases. RESULTS: We found: 1) significantly decreased bone mineral density (BMD) of the whole hand, in the rheumatoid arthritis group versus the other rheumatic diseases group, at 6 and 12 months (P < 0.05); 2) no significant decrease of bone mineral density (BMD) in other areas in the rheumatoid arthritis group; 3) no significant change of ultrasounds in either group; and 4) no significant correlation between the decrease of BMD in the rheumatoid arthritis group and clinical, biological or radiologic parameters, except for IFNgamma, whose production in whole blood cell culture was lower at entry in the rheumatoid arthritis group. CONCLUSION: DEXA bone assessment in rheumatoid arthritis was able t detect bone loss in the whole hand at 6 months.

Rheumatoid factors, anti-filaggrin antibodies and low in vitro interleukin-2 and interferon-gamma production are useful immunological markers for early diagnosis of community cases of rheumatoid arthritis. A preliminary study.

OBJECTIVE: To determine whether measurements of different autoantibodies (Ab) and cytokines are useful to distinguish very early rheumatoid arthritis (RA) from other inflammatory rheumatisms. METHODS: From a population-based recruitment, 32 patients with very early polyarthritis (median duration: 4 months) were studied. Evaluations at entry (M0), and at 6 (M6) and 12 months (M12). Ab tested: rheumatoid factors (RF) by agglutination methods and ELISA, antiperinuclear factor (APF), antikeratin Ab (AKA), anti-Sa and antinuclear Ab. Cytokine production (TNFalpha, IL2, IFNgamma, IL1beta, IL10) in whole blood cell culture (WBCC) was determined at M0. At M12, patients were classified as having RA (N = 15) or other rheumatic diseases. RESULTS: At M0, AKA/APF and anti-Sa Ab frequencies were low, 13% and 7%, respectively. While most Ab detected at M0 persisted, others appeared during follow-up, particularly APF, which rose from 13 to 40% at M12. At M6, IgM-RF was detected in two RA patients exclusively by ELISA. AKA/APF were found to be highly specific markers for RA (100% specificity). At some time during follow-up, two RF-negative RA patients were AKA-positive. In two patients, AKA and APF were present at M0 before they satisfied ACR criteria. IL2 and IFNgamma production was significantly lower (P < 0.05) for RA patients. CONCLUSION: AKA/APF and anti-Sa Ab were detected in community cases of very early RA. AKA/APF and RF detected by ELISA might contribute to an earlier diagnosis of RA. Low production of IFNgamma and IL2 in WBCC constituted a distinct immunopathological feature in very early RA patients.

Forceful sacrococcygeal injections in the treatment of postdiscectomy sciatica. A controlled study versus glucocorticoid injections.

UNLABELLED: The role of epidural fibrosis in postoperative sciatica is unclear. Few therapeutic trials have been published. We evaluated the mechanical effects of forceful saline injections through the sacrococcygeal hiatus comparatively with glucocorticoid injections. PATIENTS AND METHODS: Forty-seven patients with postdiscectomy sciatica but no evidence of compression by computed tomography or magnetic resonance imaging were included in a multicenter, randomized, controlled, parallel-group study comparing forceful injections of saline (20 ml) with or without prednisolone acetate (125 mg) to epidural prednisolone acetate (125 mg) alone. Each of the three treatments was given once a month for three consecutive months. Outcome measures were pain severity on a visual analog scale (VAS) and the scores on the Dallas algofunctional self-questionnaire on day 0, day 60, and day 120. Analysis of variance for repeated measures and Student's t test for paired series were used to evaluate the data. RESULTS: Forty-seven patients were evaluated. The VAS score improved significantly between day 0 and day 30 in the glucocorticoid group as compared to the forceful injection group (P = 0.01). No other significant differences were found across the groups. The VAS score improved steadily in the forceful injection group, producing a nearly significant difference on day 120 as compared to baseline (P = 0.08). CONCLUSION: Forceful epidural injections produced a non-significant improvement in postdiscectomy sciatica four months after surgery. Epidural glucocorticoids used alone induced short-lived pain relief.

[Acute systemic lupus erythematosus after thymectomy for myasthenia. Sequential study of lymphocyte subpopulations]. / Lupus érythémateux aigu disséminé survenu après thymectomie pour myasthénie. Etude séquentielle des sous-populations lymphocytaires.

A 35 year-old woman developed severe systemic lupus erythematosus 9 years after thymectomy for myasthenia gravis. "Seric Thymic Factor" (STF) was low; T helpers subset, T helpers/T suppressors ratio and to a lesser extent T suppressors subset were decreased. Suppressor cell function investigated by Concanavaline A lymphocyte reactivity was low. Under cyclophosphamide, plasmapheresis and steroids all clinical and biological symptoms improved but STF remained low; T helpers, T suppressors subsets and T helpers/T suppressors ratio increased but did not reach the normal range. Statistical and immunological arguments suggest that the association between systemic lupus erythematosus and myasthenia gravis did not occur only by chance. Moreover, thymectomy might have played a role by decreasing the number and function of some subpopulations of lymphocytes.

[Infectious spondylodiscitis after a cure for genital prolapse. 5 cases]. / Spondylodiscites infectieuses après cure de prolapsus génital. A propos de 5 cas.

Bacterial osteitis of the discs and the vertebrae is rare after fixing the uterus to the promontary of the sacrum. Only 30 cases have been reported in the literature. Twelve cases were found in a Rheumatology Unit over a period of 12 years from 1975-1987. The initial symptoms of septic osteitis were low back pain or sciatica, and fever. They were confirmed by radiological evidence. Bacteriological diagnosis was obtained in every case by fine needle aspiration of the disco-vertebral space retrieving staphylococci or gram-negative bacilli. The same agent was found in blood cultures in four or five cases. Potentiating pathogenic factors include urinary tract infections, prosthetic material, and surgical errors.

[Osteoarticular manifestations of pustulosis palmaris et plantaris]. / Les manifestations ostéo-articulaires de la pustulose palmo-plantaire.

In 6 patients with clinically and histologically proven pustulosis palmaris et plantaris the disease was complicated by osteo-articular manifestations. Five patients presented with articular symptoms and one with aseptic subacute osteomyelitis. The distribution of these bone and joint disorders was different from that of Sonozaki's "pustulotic arthro-osteitis": in contrast with the latter, the anterior chest was inconstantly involved whereas the spine, sacro-iliac joints and peripheral articulations were more frequently affected. Although the B27 antigen is usually absent, it seems possible to classify the rheumatic disorders of pustulosis palmaris et plantaris among seronegative spondylo-arthropathies.

[Osteoarticular manifestations of palmoplantaris pustulosis. A prospective study of 15 cases]. / Manifestations ostéo-articulaires de la pustulose palmo-plantaire. Etude prospective de 15 cas.

Between 1986 and 1989, we conducted a clinical, biochemical, radiological and scintigraphic prospective study of 15 patients (8 men, 7 women) with histologically proven palmoplantar pustulosis. In 70 percent of the cases the time interval between the first cutaneous and the first osteoarticular signs was 2 years. Anterior thoracic clinical manifestations were frequent. The joints and the numbers of patients involved were: sternoclavicular (12), manubriosternal (6), sternocostal (5), intervertebral (11), sacroiliac (6) and peripheral (10). Two patients had osteitis. The clinical, radiological and scintigraphic findings, as well as the distribution of these arthropathies over the anterior thorax (i.e. over a sternocostoclavicular complex with numerous ligaments), suggest a preference for entheses. Despite the absence of link with the HLA B27 antigen, the frequent association with pelvic and spinal lesions indicate that the articular disease of palmoplantar pustulosis is a spondyloarthropathy.

[Erosive arthropathies in Crohn disease. Apropos of 3 cases]. / Arthropathies érosives au cours de la maladie de Crohn. A propos de 3 observations.

Three unusual cases of destructive joint lesions in patients with Crohn's disease are reported. One patient with chronic enteropathic polyarthritis developed erosions of the wrists. The other two patients had spondyloarthropathic disease; erosions developed in the right hip in one and in the hips, knees and tibiotarsal joints in the other. The few similar cases reported in the literature are reviewed.
