Subclinical synovitis impact on the progression of lupus joint disease: A 10-year longitudinal multicenter study

OBJECTIVE

To determine the effect of subclinical synovitis on the progression of joint disease in a cohort of patients with systemic lupus erythematosus over a mean follow-up of 10 years.

METHODS

A longitudinal follow-up of 96 patients diagnosed with lupus was performed. All patients were considered clinically free of joint disease or with minimal joint impairment at baseline and were studied through ultrasound study of their dominant hand to assess the prevalence of subclinical synovitis. Now, over 10 years after we contacted them and reviewed their evolution to determine the impact of had or had not been diagnosed with subclinical synovitis in their current joint condition.

RESULTS

Thirty-one of the 91 reached patients developed clinical progression in their joint manifestations (at least one ordinal degree of worsening). Of these, 23 (74,9%) had demonstrated subclinical synovitis at baseline. In the group of patients who did not progress clinically, 46 (76,6%) did not have this finding at the start of follow-up (p < .01, OR 9,44 95%CI 3,46-25,74). The patients in whom clinical progression was demonstrated had worse combined ultrasound scores than the rest of the patients: 6,41 SD 1,45 vs. 1,15 SD 0,97 (p < .01).

CONCLUSIONS

The finding of subclinical synovitis in patients with systemic lupus erythematosus is associated with the development of joint disease progression both clinically and ultrasonographically.

Evidence for the Use of Secukinumab in Patients with Radiographic and Non-radiographic Axial Spondyloarthritis in the Last 5 Years

Axial spondyloarthritis (axSpA) is an inflammatory rheumatic disorder that causes chronic pain, primarily in the spine and sacroiliac joints. It is characterized by the presence of type 1 major histocompatibility complex HLA-B27 genetic marker, arthritis in peripheral joints, enthesitis and/or dactylitis and extra-articular manifestations. Current guidelines recommend biological therapy when first-line therapy is not sufficiently effective. The finding that the interleukin (IL)-17 axis is vital for the pathogenesis of axSpA propelled the development of secukinumab, a fully human monoclonal antibody directed against IL-17A. The present review provides evidence on the efficacy and safety of secukinumab in the treatment of radiographic and non-radiographic axSpA from nine randomized controlled phase III trials, as well as evidence from real-world observational analyses. The primary endpoint in six clinical trials was the proportion of patients meeting the Assessment of SpondyloArthritis international Society criteria for either 20% or 40% improvement (ASAS20, ASAS40) at week 16. Significantly more patients achieved the primary endpoint with secukinumab compared with placebo in all the studies except MEASURE 4. Both clinical trials and real-world studies showed significant improvements in the secondary endpoints of disease activity, quality of life, and pain and fatigue relative to placebo. The benefits of secukinumab were generally sustained during longer-term (up to 5 years) treatment. Overall, secukinumab was well tolerated with a low frequency of adverse events and treatment persistence was high in the real-world setting. Although indirect comparisons suggest that secukinumab and adalimumab have comparable efficacy and safety, they are being directly compared in the ongoing SURPASS study. During the current coronavirus disease 2019 (COVID-19) pandemic, it is advisable to continue biological therapy in patients who do not have severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection, but interrupt treatment during an infection, reinitiating once the patient has recovered from the infection. In conclusion, secukinumab is a largely safe and effective treatment for radiographic and non-radiographic axSpA.

Prevalence of subclinical synovitis of the hand in patients with systemic lupus erythematosus

OBJECTIVES

To determine the prevalence of subclinical synovitis in Lupus patients without peripheral joint symptoms, in those with arthralgias without arthritis and those with episodic arthritis but without radiological structural damage.

METHODS

We conducted a multicentre cross-sectional study. Patients with lupus from those three categories were recruited to take part in a greyscale ultrasound scan performed by an expert blinded rheumatologist. Data from a historical control group from a previous study was also included for comparisons. Images were assessed separately in order to determine the presence and level of synovitis following Eular recommendations.

RESULTS

Ninety-six patients (88.5% female) with an average age of 40 ± 6.2 years old, were included. SLICC/ACR score was 0.6 ± 0.3 in the group without joint symptoms (group 0), 0.8 ± 0.3 in the group with arthralgias (group I) and 1.1 ± 0.4 in the group with episodic arthritis. The global prevalence of subclinical synovitis was 38.5%. In group 0, that prevalence was 30%. The time since onset of symptoms of patients with subclinical synovitis was longer than the rest of the patients (9.4 ± 2.2 vs 6.5 ± 4.0 years, P < 0.001). No other remarkable association was founded with clinical features of the disease.

CONCLUSIONS

This is the first study focused on subclinical synovitis in patients with lupus. Other previous studies had included patients with different levels of arthropathy. Subclinical synovitis does exist in lupus patients in over a third of patients. Its meaning remains unclear and must be a topic of further studies.

Tapentadol versus tramadol in the management of low back pain in the emergency department: Impact of use on the need for reassessments

Nontraumatic musculoskeletal disorders are the main reason for presentation to the emergency department (ED), with rachialgia (back pain) being the most common reason to request medical assessment among them. This also generates the highest demand for reassessments due to poor pain control or onset of adverse reactions to the treatment prescribed in the initial assessment.A retrospective observational study based on usual clinical practice was conducted in patients attending the ED due to low back pain during a period of 24 months. The primary objective was to determine the demand for reassessments in the ED by these patients in the following 30 days, according to the type of therapeutic approach used in the initial assessment.A total of 732 patients who requested medical assessment due to back pain in the ED of our hospital were analyzed, 91 of whom were treated with tapentadol whereas 641 received another treatment. In the first month after the initial assessment, reassessments were less common in the tapentadol group; this difference was significant from days 8 to 15 (P = 0.001, odds ratio [OR] 0.252 with 95% confidence interval [CI] 0.100-0.635) and days 15 to 30 (P < 10, OR 0.277 with 95% CI 0.136-0.563). Patients who received tapentadol also had a better clinical evolution of pain compared to those who did not receive it (P < 10) and to those who received tramadol (P < 10).In this study in patients with back pain, tapentadol shows clear advantages over the other analgesics analyzed, in terms of pain control and less need for reassessments.

Fatal outcome in a case of dermatomyositis and Hamman-Rich syndrome

We present the fatal outcome in a 31-year-old woman of Latin-American origin diagnosed with dermatomyositis. There were three months between death and the onset of symptoms. The initial presentation was normal dermatological symptoms to which were shortly added clinical signs of effects on the lungs, as was shown radiologically and through pulmonary function tests which were subsequently identified histologically as Hamman-Rich syndrome. The patient was treated with high doses of corticosteroids, intravenous (IV) immunoglobulin, cyclophosphamide and cyclosporin. We carried out a review of the literature on pulmonary compromise in dermatomyositis, clinical and anatomopathological forms and treatment alternatives.
