Septic arthritis is a life-threatening rheumatological syndrome that is highly related to a patient's immune status and comorbidities, and although the most common clinical presentation is rapid-onset monoarthritis, it can also appear as subacute or chronic joint swelling. In these cases, differential diagnosis is more challenging, but early diagnosis and treatment is no less urgent to ensure a good global prognosis and the best outcome of the affected joint. Anaerobic microorganisms, such as Parvimonas micra, are an uncommon cause of septic arthritis (less than 5% of cases) but may be the cause of subacute arthritis. Knowledge about Parvimonas micra is important, as it is difficult to culture in the laboratory and generates a synovial fluid with atypical characteristics for septic arthritis so that, if not suspected, its diagnosis can be easily overlooked and underdiagnosed. We present the case of a 76-year-old woman with subacute arthritis of the left knee, describe the difficult diagnosis and treatment of its unexpected cause (Parvimonas micra), and review previously described cases, identifying the possible common comorbidities that may help clinicians easily find and treat this cause of subacute septic arthritis.
RESUMO
OBJECTIVES: To evaluate the association between liver fibrosis and the HLACw6 allele in psoriatic arthritis (PsA) patients. METHODS: A retrospective longitudinal study involving PsA patients with determination of the HLA-Cw6 allele was performed. Liver fibrosis was estimated by using the FIB-4 (fibrosis-4) score. A multivariate logistic model was undertaken to assess the odds ratio (OR), with its 95% confidence interval, of liver fibrosis after adjustment for potential confounding factors. RESULTS: A total of 209 PsA patients were included: 25.3% HLA-Cw6 were positive, 59.8% were receiving biological disease-modifying anti-rheumatic drugs (bDMARDs), 29.6% had arterial hypertension (AHT), 24% dyslipidaemia, and 4.2% acute myocardial infarction (AMI). The HLA-Cw6 allele was more frequent in PsA patients with normal FIB-4 values (p=0.024), as opposed to AHT (p=0.002), AMI (p=0.023) and dyslipidaemia (p=0.030), which were found more frequently in subjects with altered FIB-4 values. The presence HLA-Cw6 and the use of bDMARDs were confirmed as protective factors against liver fibrosis (OR 0.210, 0.062-0.707, p=0.012 and OR 0.397, 0.166-0.949, p=0.038, respectively). Conversely, AHT emerged as a risk factor (OR 2.973, 1.125-7.858, p=0.028). CONCLUSIONS: In PsA, the HLA-Cw6 allele and bDMARDs behave as protective factors for liver fibrosis, while AHT is an independent risk factor.

OBJECTIVE: To analyze the relationship among enthesis ultrasound (US) lesions and radiological structural damage in psoriatic arthritis (PsA) patients. METHODS: Consecutive PsA patients with swelling of at least 1 of the 2nd to 5th metacarpophalangeal joints were included. Clinical and demographic data were collected. The Madrid Sonographic Enthesitis Index (MASEI) was selected to evaluate the enthesis, with its total score and MASEI-activity and MASEI-structural damage subscores. The modified Sharp van der Heijde method for PsA and the New York criteria for sacroiliitis were selected to evaluate cumulative bone damage on X-rays. RESULTS: Twenty-seven patients were included. Male gender, older age, longer PsA duration and acute reactant factors were associated with greater bone cumulative damage. Enthesis tendon thickening, enthesophytes, total MASEI and the MASEI-structural damage subscore showed significant correlations with radiographic peripheral and sacroiliac damage scores. Tendon thickening and enthesophytes were the enthesis lesions more frequently associated with radiographic damage in PsA. CONCLUSION: The enthesis MASEI score was associated with axial and articular radiographic structural damage in PsA patients. The MASEI-structural damage subscore correlated better with cumulative bone damage in PsA than the MASEI-activity subscore.

OBJECTIVE: To analyse the frequency of power Doppler (PD) enthesitis in active axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) patients and its potential usefulness in clinical practice. METHODS: A prospective multicentre cross-sectional study in patients with axSpA and PsA with active disease was undertaken. Patients underwent bilateral ultrasound (US) examination of the peripheral entheses according to the Madrid Sonographic Enthesis Index (MASEI). The MASEI and Outcome Measures in Rheumatology (OMERACT) PD enthesitis definitions were checked. An inter-reader analysis of recorded videos was performed to determine reliability. RESULTS: Sixty-four consecutive patients were included. The mean DAS28 (3.9 ± 1.3) for peripheral involvement, mean BASDAI (5.6 ± 2.2) for axial involvement, and CRP values (10 ± 10.9) reflected moderate-high disease activity at baseline. The mean global MASEI score was 29.4 (± 11.4), and 55 patients (86%) scored ≥ 18 (proposed cut-off point to diagnose SpA). At the patient level, abnormal US findings consistent with at least one enthesis showing a PD signal were observed in 52 (81.3%) patients using the MASEI PD definition and 48 (75%) using the OMERACT PD definition, without significant variation between axSpA and PsA. The inter-reader reliability was excellent (kappa = 0.92 for MASEI PD and 0.86 for OMERACT PD). CONCLUSIONS: PD enthesitis was found in the majority of patients with active axSpA and PsA, independent of axial or peripheral affectation. Both MASEI and OMERACT PD definitions were useful in detecting active enthesitis. These findings support the usefulness of a PD US evaluation of entheses in the assessment of axSpA and PsA. Key Points ⢠PD enthesitis is a very common finding in patients with active axSpA and PsA ⢠Both MASEI and OMERACT PD definitions are useful to detect active enthesitis ⢠US enthesitis may reveal information in axSpA and PsA.

Rheumatoid arthritis (RA) prevalence is believed to be around 1% worldwide, although it varies considerably among different populations. The aim of EPISER2016 study was to estimate the prevalence of RA in the general adult population in Spain. We designed a population-based cross-sectional study. A national survey was conducted between November 2016 and October 2017 involving a probabilistic sample from the general population aged 20 years or older. Subjects were randomly selected for phone screening using a computer-assisted telephone interviewer system. Positive RA screening results were evaluated by a rheumatologist. Cases fulfilled the 1987 ACR and/or the 2010 ACR/EULAR criteria; previous diagnosis established by a rheumatologist and clearly identified in medical records were also accepted regardless of the criteria used. Prevalence estimates with 95% CI were calculated taking into account the design of the sample (weighting based on age, sex, and geographic origin using as a reference the distribution of the population in Spain). 4916 subjects participated in the study and 39 RA cases were confirmed. RA estimated prevalence was 0.82% (95% CI 0.59-1.15). Mean age of RA cases was 60.48 (14.85) years, they were more frequently women (61.5%), from urban areas (74.4%), non-smokers (43.6%), and with a high body mass index (53.8% with overweight). Extrapolating to the population in Spain (approximately 37 million are ≥ 20 years old), it was estimated that there were between 220,000 and 430,000 people aged 20 years or older with RA. No undiagnosed cases were detected, which could be related to the establishment of early arthritis clinics around the country, increasing the rates of diagnosis during early phases of RA.

OBJECTIVE: The prevalence of psoriatic arthritis (PsA) is very heterogeneous. There are no data on its frequency in the general population in Spain. The aim of EPISER2016 study was to estimate the prevalence of PsA in people aged ≥20 years in Spain. METHODS: Cross-sectional multicenter population-based study. Subjects from all the autonomous communities in Spain were randomly selected using multistage stratified cluster sampling. Participants in each of the municipalities randomly selected for the study were administered a telephone-based questionnaire to screen for the study diseases. If the participant reported being previously diagnosed, rheumatologists from the participant's reference hospital confirmed the diagnosis based on a review of the clinical history. Subjects not previously diagnosed but whose screening result was positive based on symptoms received a second telephone call from the investigating rheumatologist in order to evaluate the suspicion. If the suspicion remained, an appointment was made at the reference hospital to complete the diagnostic confirmation process according to CASPAR criteria. To calculate the prevalence and its 95% confidence interval (CI), the sample design was taken into account and weighing was calculated considering age, sex and geographic origin. RESULTS: The sample comprised 4916 subjects. The prevalence of PsA was 0.58% (95%CI: 0.38-0.87). All but 1 of the 27 cases (96.30%) had been diagnosed prior to EPISER2016. CONCLUSION: The prevalence of PsA in Spain was among the highest reported to date, only below that reported in Norway (0.67%) and slightly higher than that reported in Italy (0.42%).

INTRODUCTION: The aim of this study was to explore the usefulness of the determination of free light chains (FLC) in serum as a biomarker of flare in patients with systemic lupus erythematosus (SLE) and to analyze the differences in their discriminatory capacity with complement C3 and C4. METHODS: This was a prospective cohort study. The definition of flare was based on the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) Flare Index. The discriminatory capacity of FLC and C3 and C4 levels was compared using receiver operating characteristic (ROC) curves and the area under the curve (AUC). RESULTS: Forty-six patients were enrolled. Patients with SLE flare showed significantly lower C3 (p = 0.025) and C4 levels (p = 0.028), as well as a higher concentration of lambda light chains (λ-LC) (p = 0.028) compared with the non-flare group. λ-LC, as opposed to kappa light chains and total light chains, demonstrated a discriminatory capacity for detecting the presence of SLE flare (AUC 0.781), with 100% sensitivity, 65% specificity, and 69.6% of patients correctly classified for a cutoff point of ≥ 19.5 mg/L. Complement C3 and C4 also showed a high discriminatory capacity for SLE flare (AUC 0.804 and 0.837, respectively). Comparing λ-LC, C3, and C4, the last one demonstrates better discriminatory capacity for SLE flare with the highest AUC (0.837; 95% CI 0.663-1.000). CONCLUSIONS: λ-LC have good discriminatory capacity for SLE flare and could be useful as a biomarker of SLE exacerbation.Key Points⢠The usefulness of free light chains as a biomarker could be compared with complement.⢠Lambda free light chains have good discriminatory capacity for SLE flare.⢠Free light chains are a promising marker of SLE activity.

OBJECTIVE: To analyze the trend of orthopedic surgery (OS) rates on patients with rheumatoid arthritis (RA). METHODS: Retrospective observational study based on information provided by the Spanish National System of Hospital Data Surveillance. All hospitalizations of patients with RA for orthopedic surgery [total hip arthroplasty (THA), total knee arthroplasty (TKA), arthrodesis, and upper limb arthroplasty (ULA)] during 1999-2015 were analyzed. The age-adjusted rate was calculated. Generalized linear models were used for trend analysis. RESULTS: There were 21,088 OS in patients over 20 years of age (77.9% women). OS rate adjusted by age was 754.63/100,000 RA patients/year (women 707.4, men 861.1). Neither an increasing nor a decreasing trend was noted for the total OS. However, trend and age interacted, so in the age ranges 20-40 years and 40-60 years, an annual reduction of 2.69% and 2.97%, respectively, was noted. In the age ranges over 80 years and 60-80 years, we noted an annual increase of 5.40% and 1.09%, respectively. The average age at time of OS increased 5.5 years during the period analyzed. For specific surgeries, a global annual reduction was noted in rates for arthrodesis. In THA, there was an annual reduction in patients under 80 years. In TKA and ULA, there was an annual reduction in patients under 60 years. CONCLUSION: Although the overall OS rate has not changed, there is a decrease in the rate of arthrodesis at all ages, THA in patients under 80 years of age, as well as TKA and ULA in patients under 60 years of age.

OBJECTIVE: To perform a systematic review of the literature to evaluate the use of the enthesis ultrasound Madrid Sonographic Entesis Index (MASEI) from its publication. METHODS: A systematic search of MEDLINE, EMBASE, and Cochrane Central Register databases was performed. The search strategy was constructed to identify publications containing terms related to enthesis and ultrasound. The only applied filter was studies conducted in humans. One reviewer systematically screened the search. A second reviewer verified the selection. The data extraction was focused on study characteristics, including population and components of the OMERACT filter. RESULTS: Sixty-eight of the 1581 identified studies had used MASEI, including 41 (60%) abstracts and 27 (40%) articles. Of the 27 articles, MASEI was mainly used for spondyloarthritis and related diseases in 12 (44%) articles, followed by both psoriatic arthritis and rheumatoid arthritis in five (19%) articles; however, it was also used in diseases such as Behçet disease, FM, familiar Mediterranean fever, SS, crystal arthropathies and systemic sclerosis. The feasibility of MASEI was reported in three (11%) articles, and the reliability in 12 (44%) with good to excellent values. No article evaluated the responsiveness to treatment. The construct validity of MASEI was assessed using biomarkers in seven (26%) articles, clinical examination in 13 (48%) and imaging procedures (only X-rays) in two (7%). The discriminative validity was assessed in 16 (59%) articles, not only in SpAs. CONCLUSION: MASEI is a feasible, reliable and valid ultrasound score for the study of enthesis in spondyloarthritis, psoriatic arthritis and other diseases.

OBJECTIVE: To analyze the association between enthesitis, synovitis, and peritenon extensor tendon inflammation (PTI) in psoriatic arthritis (PsA). METHODS: PsA patients with swelling of metacarpophalangeal joints were included. Greyscale and power Doppler (PD) were used for synovitis and PTI ultrasound identification. Madrid Sonographic Enthesis Index (MASEI) was used for enthesitis assessment. PD activity was evaluated using PD item of MASEI and PD Outcome Measures in Rheumatology (OMERACT) definition. RESULTS: Synovitis had no association with enthesitis. PTI was associated with PD MASEI and PD OMERACT. Only PD OMERACT showed a positive correlation with PTI. CONCLUSION: In PsA, PTI is associated to enthesitis, as opposed to synovitis.
