RESUMEN

In Susac syndrome, occlusions of pre-capillary arterioles of the brain, retina, and cochlea lead to the classical clinical triad of subacute encephalopathy, visual disturbances due to branch retinal artery occlusions and sensorineural hearing impairment. Its pathogenesis is still obscure, but it is presumed to be mediated by an autoimmune response to an as yet unknown antigen. The syndrome is considered a rare but important differential diagnosis in various neurological, psychiatric, ophthalmological, and ear-nose-throat disorders. Brain magnetic resonance imaging, retinal fluorescein angiography, and audiometry findings enable diagnosis. Early therapy may reduce relapses and improve recovery. The features of four cases of this syndrome are presented, illustrating that cooperation among different medical specialists is essential, and that treatment may be best guided by an immunologist or rheumatologist as a case manager.

RESUMEN

The validity of uterine artery embolisation (UAE ) as an alternative treatment for hysterectomy to treat symptomatic uterine fibroids has been well established. Despite its favourable outcomes, UAE is still only marginally applied in the Netherlands. The aim of this inventory is to identify factors which either restrict or facilitate the implementation of UAE. Gynaecologists and interventional-radiologists in three hospitals in Amsterdam were interviewed by means of questionnaires. One of these hospitals had ample experience in UAE for uterine fibroids, one hospital had just started providing this treatment, and one hospital did not perform UAE. Also patients with symptomatic fibroids who were scheduled for either UAE or hysterectomy were interviewed about the counselling for UAE. The following obstacles in the implementation of UAE were found: lack of knowledge about UAE , absence of a multidisciplinary protocol, and above all, the absence of UAE as one of the treatment options in the Dutch national guideline on the management of menorrhagia. 75% of all patients claimed to be well informed about UAE by their gynaecologist. Our recommendations for the implementation of UAE are: 1) adding UAE to the Dutch guideline for the management of menorrhagia with clearly defined indications and contraindications; 2) educating gynaecologists about UAE; 3) composing a patient information leaflet and a website, and 4) arranging a protocol in a multidisciplinary team.

RESUMEN

OBJECTIVES: To determine the relapse rate after discontinuing treatment in patients with rheumatoid arthritis (RA) in sustained clinical remission, to identify predictors of a relapse and to evaluate treatment response after restarting treatment. METHODS: Five-year data from the BeSt study were used, in which 508 patients with recent-onset RA were randomised into four dynamic treatment strategies, aiming at a disease activity score (DAS) ≤ 2.4. When DAS was < 1.6 for ≥ 6 months, the last disease-modifying antirheumatic drug (DMARD) was tapered and discontinued. If DAS increased to ≥ 1.6, the last DMARD was immediately reintroduced. RESULTS: During a 5-year period, 115/508 patients (23%) achieved drug-free remission. Of these, 53 patients (46%) restarted treatment because the DAS was ≥ 1.6 after a median of 5 months, 59 patients (51%) remained in drug-free remission for a median duration of 23 months and 3 (3%) were lost to follow-up. In those who restarted treatment, mean (SD) DAS increased from 1.13 (0.73) at remission before tapering to 2.18 (0.65) at restart, reflecting an increase in all four components of DAS. Multivariable predictors for restarting treatment were anti-cyclic citrullinated peptide (anti-CCP), last DMARD sulfasalazine, low baseline Health Assessment Questionnaire score and high mean DAS until remission. Of the 53 patients who restarted treatment, 39 (74%) again achieved remission 3-6 months after the restart. The median (IQR) damage progression in those who restarted treatment during the year of DAS increase was 0 (0-1) Sharp-van der Heijde units. CONCLUSION: During 5 years DAS steered treatment, nearly 25% of patients with RA achieved drug-free remission; 46% restarted DMARD monotherapy because of a relapse, the majority of whom again achieved clinical remission within 3-6 months without showing radiological progression during the relapse.

RESUMEN

OBJECTIVE: To investigate the effectiveness of 4 different treatment strategies for recent-onset rheumatoid arthritis (RA) on 2-year patient-reported outcomes, including functioning and quality of life. METHODS: A total of 508 patients with recent-onset RA were randomly assigned to 1) sequential monotherapy, 2) step-up combination therapy, both starting with methotrexate, 3) initial combination therapy, including a tapered high-dose prednisone, or 4) initial combination therapy with methotrexate and infliximab. Treatment was adjusted every 3 months if the Disease Activity Score (DAS) remained >2.4. The McMaster Toronto Arthritis Patient Preference Disability Questionnaire, the Short Form 36 (SF-36), and scores for pain, global health, and disease activity measured on a 100-mm visual analog scale (VAS) were compared between groups at baseline and every 3 months thereafter for 2 years. RESULTS: After 2 years, all patient-reported outcomes had improved significantly from baseline, irrespective of the treatment strategy. SF-36 subscale scores approached population norms for 3 physical components, and achieved population norms (P > 0.05) for bodily pain and 4 mental components. Improvement in functioning, VAS scores, and physical items of the SF-36 occurred significantly earlier in patients treated with initial combination therapies (all comparisons after 3 months: overall P < 0.001; P < 0.05 for groups 1 and 2 versus groups 3 and 4). CONCLUSION: All 4 DAS-driven treatment strategies resulted in substantial improvements in functional ability, quality of life, and self-assessed VAS scores after 2 years. Initial combination therapy led to significantly faster improvement in all patient-reported measures.

RESUMEN

OBJECTIVES: To compare the clinical and radiological efficacy of initial vs delayed treatment with methotrexate (MTX) and infliximab (IFX) in patients with recent onset rheumatoid arthritis (RA). METHODS: In a post hoc analysis of the BeSt study (for Behandel Stratagieen, Dutch for treatment strategies), 117 patients who started initial MTX+IFX were compared with 67 patients who started MTX+IFX treatment after failing (disease activity score (DAS)>2.4; median delay to IFX: 13 months) on > or =3 traditional DMARDs. If the DAS remained >2.4, the protocol dictated IFX dose increases to 6, 7.5 and 10 mg/kg. In case of a DAS < or =2.4 for > or =6 months, IFX was tapered and finally stopped. We aimed to correct for allocation bias using propensity scores. Functional ability was measured by the Health Assessment Questionnaire (HAQ), radiological progression by Sharp/van der Heijde scoring (SHS). RESULTS: Baseline differences between the initial and delayed groups were no longer significant after propensity score adjustment. At 3 years after baseline, patients treated with initial MTX+IFX experienced more improvement in HAQ over time and were less likely to have SHS progression than patients treated with delayed MTX+IFX (p = 0.034). At 2 years after IFX initiation, more patients in the initial group compared with the delayed group could discontinue IFX after a good response (56% vs 29%, p = 0.008). CONCLUSIONS: The results of this post hoc analysis suggest that using MTX+IFX as initial treatment for patients with recent onset RA is more effective than reserving MTX+IFX for patients who failed on traditional DMARDs, with more HAQ improvement over time, more IFX discontinuation and less progression of joint damage.

RESUMEN

OBJECTIVES: To compare the occurrence of drug-free remission, functional ability and radiological damage after 4 years of response-driven treatment according to four different treatment strategies for rheumatoid arthritis (RA). METHODS: Patients with recent-onset, active RA (n = 508) were randomly assigned to four different treatment strategies: (1) sequential monotherapy; (2) step-up combination therapy; (3) initial combination therapy with prednisone and (4) initial combination therapy with infliximab. Treatment was adjusted based on 3-monthly disease activity score (DAS) assessments, aiming at a DAS < or =2.4. From the third year, patients with a sustained DAS <1.6 discontinued treatment. RESULTS: In total, 43% of patients were in remission (DAS <1.6) at 4 years and 13% were in drug-free remission: 14%, 12%, 8% and 18% of patients in groups 1-4, respectively. The absence of anti-cyclic citrullinated peptide antibodies, male gender and short symptom duration were independently associated with drug-free remission. Functional ability and remission were maintained in all four groups with the continuation of DAS-driven treatment, without significant differences between the groups. Significant progression of joint damage was observed in 38% and 31% of patients in groups 3 and 4 versus 51% and 54% of patients in groups 1 and 2 (p<0.05, group 4 versus groups 1 and 2, group 3 versus group 2). CONCLUSIONS: In patients with recent-onset active RA, drug-free remission was achieved in up to 18% of patients. DAS-driven treatment maintained clinical and functional improvement, independent of the treatment strategy. Joint damage progression remained significantly lower after initial combination therapy compared with initial monotherapy.

RESUMEN

BACKGROUND: Obesity is a state of chronic low-grade inflammation that predisposes people to several diseases and that is increasingly prevalent. Rheumatoid arthritis (RA) is marked by the presence of proinflammatory cytokines and, in general, the presence of high levels of inflammatory markers is associated with a severe disease course and joint damage. OBJECTIVES: To evaluate prospectively (a) whether obesity is a risk factor for the development of RA and (b) whether the body mass index (BMI) is associated with the amount of joint destruction in early RA after 3 years' follow-up. METHODS: In a cohort of 570 patients with undifferentiated arthritis, the relation between the BMI and the development of RA during 1 year of follow-up was assessed. In a cohort of 488 patients with early RA the correlation between the BMI and degree of radiological joint destruction (Sharp-van der Heijde score) after 3 years of follow-up was determined. The findings were replicated in an independent cohort of 247 patients with early RA. RESULTS: Obesity did not influence the likelihood of developing RA. In both RA cohorts, the BMI was inversely correlated with the Sharp-van der Heijde score after 3 years' follow-up (r = -0.15, p = 0.025 for the Leiden EAC and r = -0.27, p<0.001 for the replication cohort). Linear regression analyses in both cohorts showed that the BMI was independently and inversely associated with the level of joint destruction in anti-CCP-positive patients with RA, but not in anti-CCP-negative patients. CONCLUSIONS: A high BMI is associated with a less severe disease outcome in anti-CCP-positive patients with RA.
