Thorough assessment of the effectiveness of belimumab in a large Spanish multicenter cohort of systemic lupus erythematosus patients.

OBJECTIVES: To provide an overview on the current use of belimumab (BLM) in SLE patients in clinical practice and to examine its efficacy in terms of standardized outcomes, drug survival, as well as patient and safety profiles. METHODS: A longitudinal retrospective multicentre cohort including SLE patients treated with BLM at 18 Spanish centers. Data was collected upon initiation of BLM, at 6 and 12 months after initiation, and at the last recorded visit. Changes in SLEDAI-2K, the proportion of patients who achieved LLDAS and DORIS 2021, and number of flares were compared between visits. Changes in damage, glucocorticoids use and employment status pre-BLM and post-BLM were also assessed. RESULTS: A total of 324 patients were included with a mean follow-up of 3.8 (±2.7) years. LLDAS was attained by 45.8%, 62% and 71% of patients, and DORIS by 24%, 36.2% and 52.5% on successive visits, respectively. Twenty-seven-point two percent of patients were in DORIS ≥ 50% of the visits and a 46% in LLDAS-50. Flares and number of flares were significantly lower one year after treatment with BLM and no changes in damage accrual were observed. Mean (±SD) prednisone dose was significantly reduced over time, with 70 (24%) patients discontinuing GC. CONCLUSION: Our study not only demonstrates belimumab´s efficacy in attaining treat-to-target goals in SLE patients, but also confirms its GC-sparing effect, and its prevention of flares and organ damage accrual.

Rheumatoid meningitis as a complication of long-standing rheumatoid arthritis: a case treated with rituximab.

Rheumatoid meningitis is a rare complication of long-standing rheumatoid arthritis. We present the case of a 39-year-old Bolivian woman with a history of seropositive rheumatoid arthritis of 12 years of evolution without extra-articular manifestations that develops a severe headache with vomiting. The diagnosis of rheumatoid meningitis was performed based on clinical history, blood count and biochemistry results, cerebrospinal fluid analysis and cranial magnetic resonance imaging findings. High-dose intravenous glucocorticoids were started, followed by rituximab. After treatment, a significant clinical improvement was observed and repeat magnetic resonance imaging scan confirmed an improvement of the meningeal lesions.

Determination of serum free light chains as a marker of systemic lupus flare.

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.

Influence of Antisynthetase Antibodies Specificities on Antisynthetase Syndrome Clinical Spectrum Time Course.

Antisynthetase syndrome (ASSD) is a rare clinical condition that is characterized by the occurrence of a classic clinical triad, encompassing myositis, arthritis, and interstitial lung disease (ILD), along with specific autoantibodies that are addressed to different aminoacyl tRNA synthetases (ARS). Until now, it has been unknown whether the presence of a different ARS might affect the clinical presentation, evolution, and outcome of ASSD. In this study, we retrospectively recorded the time of onset, characteristics, clustering of triad findings, and survival of 828 ASSD patients (593 anti-Jo1, 95 anti-PL7, 84 anti-PL12, 38 anti-EJ, and 18 anti-OJ), referring to AENEAS (American and European NEtwork of Antisynthetase Syndrome) collaborative group's cohort. Comparisons were performed first between all ARS cases and then, in the case of significance, while using anti-Jo1 positive patients as the reference group. The characteristics of triad findings were similar and the onset mainly began with a single triad finding in all groups despite some differences in overall prevalence. The "ex-novo" occurrence of triad findings was only reduced in the anti-PL12-positive cohort, however, it occurred in a clinically relevant percentage of patients (30%). Moreover, survival was not influenced by the underlying anti-aminoacyl tRNA synthetase antibodies' positivity, which confirmed that antisynthetase syndrome is a heterogeneous condition and that antibody specificity only partially influences the clinical presentation and evolution of this condition.

Osteonecrosis multifocal asociada a infección por el virus de la inmunodeficiencia humana / Multifocal osteonecrosis associated with human immunodeficiency virus infection

La osteonecrosis ha emergido en los últimos años como una complicación osteoarticular potencialmente discapacitante en pacientes con infección por el VIH. Existe una alta prevalencia de factores de riesgo tradicionales para el desarrollo de osteonecrosis en estos pacientes, pero también factores asociados a la infección por VIH en sí misma y el tratamiento antirretroviral de gran actividad. La osteonecrosis asociada a VIH suele afectar con mayor frecuencia a las caderas, con tendencia a la bilateralidad, pero la afección simultánea de 3 o más localizaciones (osteonecrosis multifocal) ha sido descrita de forma infrecuente. Presentamos el caso de un paciente varón de 49 años, con infección por el VIH de largo tiempo de evolución y tratamiento antirretroviral, que desarrolló osteonecrosis con afección simultánea de caderas, rodillas, tobillos y tarsos (AU)

The osteonecrosis has emerged in the last years as a potentially disabling osteoarticular complication in HIV-infected patients. There is a high prevalence of traditional risk factors for osteonecrosis development in these patients, but they also have factors associated to HIV infection in itself and the high activity antiretroviral therapy. The HIV-associated osteonecrosis often affects the hips, with a trend to bilaterally, but concomitant affection of 3 or more locations (multifocal osteonecrosis) has been infrequently reported. We present the case of a 49-years-old male patient, with long duration HIV infection and antiretroviral therapy, who developed osteonecrosis with concomitant affection of hips, knees, heels and tarsus (AU)
