- Risk Factors for Intraarticular Heterotopic Bone Formation in the Temporomandibular Joint in Juvenile Idiopathic Arthritis. [Journal Article]
- JRJ Rheumatol 2018 May 15
- CONCLUSIONS: HBF within the TMJ is relatively common in patients with JIA receiving IAC injections for TMJ arthritis. Future prospective studies are required to delineate the risks posed by the injections themselves as opposed to the underlying disease activity, as well as to evaluate alternative forms of local therapy to the TMJ.
- Chikungunya virus infection in Aruba: Diagnosis, clinical features and predictors of post-chikungunya chronic polyarthralgia. [Journal Article]
- PlosPLoS One 2018; 13(4):e0196630
- CONCLUSIONS: We identified 269 CHIKV patients after the first outbreak of Asian genotype CHIKV in Aruba in 2014-2015. RT-PCR yielded 59 (28%) additional CHIKV diagnoses compared to IgM antibody detection alone. Arthralgia, fever and skin rash were the dominant acute phase symptoms. pCHIK-CPA longer than 1 year affected 26% of cases and was predicted by female gender, high ACR-score and CHIKV-RNA detection beyond 7 days of symptom onset.

Group A beta-hemolytic streptococcus can cause several postinfectious, nonsuppurative immune- mediated diseases including acute rheumatic fever, poststreptococcal reactive arthritis, pediatric autoimmune neuropsychiatric disorders, and poststreptococcal glomerulonephritis. Except for sporadic outbreaks, poststreptococcal autoimmune syndromes occur most commonly in sub-Saharan Africa, India, Australia, and New Zealand. Children younger than three years are rarely affected by group A streptococcus pharyngitis or rheumatic fever, and usually do not require testing. Rheumatic fever is a rare condition that presents as a febrile illness characterized by arthritis, carditis or valvulitis, and neurologic and cutaneous disease, followed many years later by acquired valvular disease. Recurrence rates are high. In addition to evidence of recent streptococcal infection, two major or one major and two minor Jones criteria are required for diagnosis. Electrocardiography, chest radiography, erythrocyte sedimentation rate, and an antistreptolysin O titer are the most useful initial tests. Echocardiography is recommended to identify patients with subclinical carditis. The arthritis usually responds within three days to nonsteroidal anti-inflammatory drugs. Poststreptococcal reactive arthritis is nonmigratory, can affect any joint, and typically does not respond to aspirin. Pediatric autoimmune neuropsychiatric disorders affect the basal ganglia and are manifested by obsessive-compulsive and tic disorders. The presentation of poststreptococcal glomerulonephritis ranges from asymptomatic microscopic hematuria to gross hematuria, edema, hypertension, proteinuria, and elevated serum creatinine levels.
- Effectiveness and safety of anakinra in gout patients with stage 4-5 chronic kidney disease or kidney transplantation: a multicentre, retrospective study. [Journal Article]

- CONCLUSIONS: Anakinra may be a safe therapeutic option for gout patients with advanced CKD. Further randomized controlled studies are required to confirm our results.
- Treatment of chikungunya chronic arthritis: A systematic review. [Review]
- RARev Assoc Med Bras (1992) 2018; 64(1):63-70
- CONCLUSIONS: When the manifestations of CHIK become chronic and, the longer they last, more complications arise. Polyarthralgia can be immaterial, distancing individuals from their daily-life activities. Anti-inflammatory drugs (either steroid or not), in addition to immunosuppressants, homeopathy and physiotherapy are measures of treatment that, according to the literature, have been successful in relieving or extinguishing symptoms. However, it is fundamental that studies of CHIK treatment be further developed.
- [Methods of efficacy assessment of the knee joint radiosynoviorthesis- personal experience]. [Journal Article]
- WLWiad Lek 2018; 71(1 pt 1):10-16
- CONCLUSIONS: Conclusions: 90Yttrium RS is effective treatment of recurrent knee joints effusion in patients with RA i SPA. RS despite being local treatment decreases unspecific inflammatory process and systemic disease activity among patients with RA i SPA. The anatomic period of affected knee joints has negative correlation with treatment efficacy. 90Yttrium RS is safe procedure, favourable profile changes of cartilage and bone turn-over markers after therapy indicates protective influence of RS on these structures. The treatment response based on physical examination, subjective patient's evaluation, acute phase laboratory parameter levels and appropriate scores, questionnaires and imaging exams is fast and long-lasting.
- Mice with miR-146a deficiency develop severe gouty arthritis via dysregulation of TRAF 6, IRAK 1 and NALP3 inflammasome. [Journal Article]
- ARArthritis Res Ther 2018 Mar 15; 20(1):45
- CONCLUSIONS: Collectively, these observations suggest that miR-146a provides negative feedback regulation of gouty arthritis development and lack of miR-146a enhances gouty arthritis via upregulation of TRAK6, IRAK-1, and the NALP3 inflammasome function.
- Residual disease activity in rheumatoid arthritis patients treated with subcutaneous biologic drugs that achieved remission or low disease activity: a longitudinal observational study. [Journal Article]

The aim of this study was to evaluate the residual disease activity (RDA) and function in rheumatoid arthritis (RA) patients treated with subcutaneous biologic drugs that achieved a status of remission and low disease activity (LDA) according to the various indices validated for RA and to explore the factors associated with RDA. We consecutively enrolled RA patients that started a new subcutaneous biologic treatment. At baseline and after 3 and 6 months of treatment, we assessed the rate of patients that achieved remission or LDA using the Disease Activity Score on 28 joints, Clinical Disease Activity Index, Simplified Disease Activity Index, and American College of Rheumatology/European League Against Rheumatism remission criteria. The presence of RDA was evaluated as the rate of patients with at least tender joint count > 1, swollen joint count > 1, pain on VAS > 10 mm, general health (VAS) > 10, patient's disease activity (VAS) > 10, physician disease activity (VAS) > 10, and C reactive protein > 1 mg/dl. We also evaluated the impaired function defined as HAQ score > 0.5. Factors associated to RDA were also investigated. Ninety-three adult patients with RA were enrolled. At 6 months, RDA occurred mostly at the level of Patient's reported outcome items and less frequently in tender and swollen joints and acute-phase reactants. Interestingly, about one fourth of patients in LDA and up to one fifth of patients in remission had residual functional impairment with an HAQ score greater than 0.5. RDA in RA was present even in patients with remission or LDA, especially for the patient's reported outcome. Impaired function was also present in a significantly rate of patients.

Acute lymphoblastic leukemia (ALL) is the most common childhood neoplasia and may present with arthralgia and arthritis, with the risk of misdiagnosis and diagnostic delay. We describe in detail arthropathy (arthritis/arthralgia) among children with leukemia as the children's laboratory results, misdiagnosis, and treatment before the diagnosis of ALL and the diagnostic delay. In this retrospective cohort study, we reviewed records of 286 children aged 1-15 years diagnosed with ALL from January 1992 to March 2013. We identified 26 children with arthralgia and 27 children with arthritis. The majority of the children had one or two joints involved (arthralgia 72%, arthritis 42%), and most often hips and knees. Morning stiffness was not reported. Imaging of affected joints was included in the initial workup of 77% of children with ALL and arthropathy, and 66% was abnormal. Misdiagnosis as JIA occurred in 26% and 71% of these children received treatment with intraarticular corticosteroids. The diagnostic delay was 3 weeks longer for the children with arthritis than those with arthralgia (median 54 vs 36 days), primarily as a consequence of a longer first doctor's delay. Compared to the children with arthralgia, the children with arthritis were more often misdiagnosed and treated with intraarticular steroid before the diagnosis of ALL. They also had longer diagnostic delay, primarily as a consequence of a longer first doctor's delay.

Once remission or low disease activity (LDA) is attained in established rheumatoid arthritis (RA) patients, attempting disease-modifying anti-rheumatic drug (DMARD) tapering appears to be a viable option to avoid patient overtreatment. Potential benefits include reduction in the treatment burden and the risk of adverse events, although the latter has not been demonstrated convincingly. The feasibility of DMARD discontinuation has been tested in numerous studies or trials. All have revealed a high risk of relapse, ranging from 56%-87% at one year. Although remission/LDA can usually be re-established by re-initiation of the previous treatment, the associated risk appears to be more harmful than beneficial. DMARD tapering, either by dose reduction or by injection spacing, is conceptually more acceptable and two superiority randomized controlled trials (RCTs) comparing half-dose etanercept to full-dose continuation demonstrated no significant difference at one year. By contrast, two equivalence RCTs that tested disease activity-guided dose optimization by progressive etanercept and adalimumab injection spacing versus continuation revealed an increased risk of acute flare. Interestingly, one of these also demonstrated the equivalence of increasing injection spacing and standard of care in terms of recurrent flare and overall disease activity over the 18-month follow-up period. The risk of structural damage progression was minimal or null. Reintroduction of DMARD at the previous dose was associated with remission being achieved in the majority of patients who flared. Tapering strategies that adhere to the Tight Control and Treat-to-Target principles appear to be suitable options for RA patients who have achieved sustained remission or low disease activity.
