The role of ultrasonography in assessing remission in juvenile idiopathic arthritis: a systematic review.

Musculoskeletal ultrasound (MSUS) is an important measurement tool in pediatric rheumatology as it detects subclinical disease activity and enables clinicians to treat patients during "the window of opportunity". However, the role of MSUS in assessing remission in JIA patients is not well-defined. This systematic review aimed to provide the most up-to-date published literature regarding the added value of MSUS in JIA patients in remission. This systematic review followed the preferred reporting items for systematic reviews guidelines. Original articles from PubMed and Scopus, published until February 7th 2022, and tackling the role of MSUS in JIA patients in remission were included. Eight studies met the inclusion criteria. They were published between 2011 and 2019 and included 356 children with JIA. Remission criteria were unanimous and relied on the Wallace criteria. Subclinical synovitis and Power Doppler signal (PD) were found in up to 84% and 33% of patients in remission, respectively. In most of the studies, predictors of future flares were abnormal MSUS findings at baseline particularly the presence of PD signal and patients without medication.  Conclusion: Published data indicate that JIA children in remission may have abnormal MSUS findings including PD signal. The application of a specific scoring system for the pediatric joint may be helpful in homogenizing outcomes in future trials. Further studies on this matter are needed to ascertain the specific implication for each subset for a better holistic approach. What is Known: • In these recent years, significant progress has been made on building the evidence base for MSUS in pediatric rheumatology, particularly in juvenile idiopathic arthritis (JIA). • In the frame of the OMERACT ultrasound pediatric subtask force, standardized musculoskeletal US examination for the pediatric population was established. What is New: • Published data indicate that JIA children in remission may have abnormal MSUS findings including PD signal. The role of MSUS in assessing remission in JIA is still not well-defined. • The application of a specific scoring system for the pediatric joint may be helpful in homogenizing outcomes and comparing results.

Tapering biologics in axial spondyloarthritis: A systematic literature review.

INTRODUCTION: The emergence of biologics has improved the management of patients with rheumatic disease, mainly with spondyloarthritis (SpA). Sustained remission has become a reachable goal thanks to the treat to target strategy. Contrary to rheumatoid arthritis, data on biologic optimization among SpA patients in remission is scarce and still a subject of debate. The main objective of this systematic review was to provide the most up-to-date published literature regarding biologic tapering in axial spondyloarthritis. METHODS: This systematic review followed the preferred reporting items for systematic reviews guidelines. Original articles from Pubmed and Scopus, published until December 20th 2021, and tackling tapering strategies of the biologics in patients with axial SpA were included RESULTS: Fourteen studies met the inclusion criteria. They were published between 2008 and 2020. The most studied molecules were Etanercept (ETN) (n = 13), Infliximab (IFX) (n = 6), Adalimumab (ADA) (n = 5), certolizumab pegol (CZP) (n = 2), Golimumab (n = 1) and ETN biosimilar. There are no studies published regarding anti-IL 17 tapering strategy. Patient-tailored dose reduction of anti TNF-α agents was successful in preserving stable low disease activity in most of the studies with remission rates ranging between 20.2 % and 93.7 %. Complete treatment discontinuation is associated with a high risk of flares. CONCLUSION: To conclude, published data indicate that a progressive tapering strategy for anti TNF-α therapy is successful among axial SpA in sustained remission. However, further studies with more homogenized tapering strategies are needed in order to ascertain the specific implication of each subset for a better holistic approach.

Lower urinary tract symptoms in rheumatoid arthritis and spondyloarthritis male patients versus controls.

Background. We aimed to evaluate the severity of lower urinary tract symptoms (LUTS) in rheumatoid arthritis (RA) and spondyloarthritis (SpA) male patient versus control, then to determine the relation of LUTS with rheumatic diseases (RD) characteristics and with erectile dysfunction (ED).Methods. We conducted a cross-sectional case control study including 50 men with RA or SpA and 50 healthy controls. LUTS were evaluated by the International Prostate Symptom Score (IPSS). LUTS bother was evaluated by the Quality of life (QoL) score, which ranges from 0 to 6. LUTS bother was considered if QoL score exceeded 2. Moreover, erectile function was assessed by the International Index of Erectile Function-5 (IIEF5) (ED if score < 21).Results. LUTS were significantly more severe in RD patients than controls (p = 0.03). However, there was no difference between the two groups in LUTS bother (QoL) (p = 0.2). Comparing RA and SpA showed no difference as to the severity of LUTS or effect of bother on QoL (p = 0.13, p = 0.5). The prevalence of ED in RD patients was not significantly higher than controls (80% versus 70%; p = 0.2).There were also no differences either between RA and SpA groups (p = 0.74).The severity of LUTS for patients with RD (RA and SpA) was significantly associated with age (p = 0.001), age at disease onset (p = 0.002) and ED (p = 0.008).Conclusion. According to our study, men with RD seem to be exposed to more severe LUTS than controls. Also, the severity of LUTS was associated with ED, age of patients and the age of disease onset.

Sarcoidosis and spondyloarthritis: A coincidence or common etiopathogenesis?

BACKGROUND: Sarcoidosis is a multisystem granulomatous disease. Co-existence with spondyloarthritis (SA) has been more described as an adverse effect of anti-TNF α therapy than an association. We report herein a case of a typical sarcoidosis confirmed by histological proofs and an advanced SA with a bamboo column. CASE PRESENTATION: A 48-years-old woman presented with inflammatory back pain for 5 years and ankle swelling for 1 year. On physical examination, she had an exaggerated dorsal kyphosis and disappearance of lumbar lordosis with limitation in motion of the cervical and lumbar spine. Laboratory tests did not show an inflammatory syndrome or hypercalcemia. Plain radiographies of the spine and pelvic revealed a triple ray appearance with sacroiliitis grade 4. Chest radiography and CT confirmed the presence of bilateral hilar lymph nodes and parenchymal nodes. Bronchoscopy and biopsies were performed showing non-calcified granulomatous reaction without cell necrosis. The diagnosis of SA was performed based on 9 points of Amor criteria associated with pulmonary sarcoidosis. She was treated with 15 mg per week of methotrexate and 1mg/kg/day of prednisone for pulmonary disease with good outcomes. CONCLUSIONS: Sarcoidosis may be associated to SA besides paradoxical drug effect. The same physio pathological pathways mediate by TNF α are arguments for association than hazardous coincidence.
