Effectiveness of ustekinumab in patients with psoriatic arthritis in a real-world, multicenter study.

OBJECTIVE: To assess the effectiveness and survival of ustekinumab (UST) among patients with psoriatic arthritis (PsA) treated under routine clinical care. METHODS: Multicenter study. Epidemiological and clinical data was collected through electronic medical records of all patients with PsA who started UST in 15 hospitals of Spain. RESULTS: Two hundred and one patients were included, 130 (64.7%) with 45 mg and 71 (35.3%) with 90 mg. One hundred and thirty one patients (65.2%) had previously received another biological therapy. The median baseline DAS 28 ESR was 3.99, and Psoriasis Area and Severity Index (PASI) was 3. Overall, there was a significant decrease in DAS66/68 CRP, swollen joint count (SJC), tender joint count (TJC), and PASI in the first month of treatment, with earlier improvement in skin (PASI) than joints outcomes. Survival was numerically lower in patients with UST 45 mg (58.1%) than 90 mg (76.1%), although significant differences were not found (p = 0.147). When comparing naïve and < 1 TNF blocker versus > 2 TNF blocker-experienced patients, a significantly earlier response was seen in the former group regarding SJC (p = 0.029) at 1 month. Fifty-one patients (25.3%) stopped UST due to joint inefficacy and 4 patients due to adverse events (1.9%). Drug survival was significantly better in patients with fewer lines of previous biological agents (p = 0.003 for < 1 TNF blocker versus > 2 TNF blocker users). CONCLUSIONS: UST was effective in PsA patients in a routine clinical care setting. Patients with UST 90 mg and fewer lines of previous biologics achieved better and faster responses. Key Points • Largest cohort of patients with PsA in treatment with UST with specific rheumatological indication. • First cohort of patients with PsA comparing effectiveness of UST according to 45/90 mg dose.

Differences in clinical manifestations and increased severity of systemic lupus erythematosus between two groups of Hispanics: European Caucasians versus Latin American mestizos (data from the RELESSER registry).

BACKGROUND: Systemic lupus erythematosus (SLE) is regarded as a prototype autoimmune disease because it can serve as a means for studying differences between ethnic minorities and sex. Traditionally, all Hispanics have been bracketed within the same ethnic group, but there are differences between Hispanics from Spain and those from Latin America, not to mention other Spanish-speaking populations. OBJECTIVES: This study aimed to determine the demographic and clinical characteristics, severity, activity, damage, mortality and co-morbidity of SLE in Hispanics belonging to the two ethnic groups resident in Spain, and to identify any differences. METHODS: This was an observational, multi-centre, retrospective study. The demographic and clinical variables of patients with SLE from 45 rheumatology units were collected. The study was conducted in accordance with Good Clinical Practice guidelines. Hispanic patients from the registry were divided into two groups: Spaniards or European Caucasians (EC) and Latin American mestizos (LAM). Comparative univariate and multivariate statistical analyses were carried out. RESULTS: A total of 3490 SLE patients were included, 90% of whom were female; 3305 (92%) EC and 185 (5%) LAM. LAM patients experienced their first lupus symptoms four years earlier than EC patients and were diagnosed and included in the registry younger, and their SLE was of a shorter duration. The time in months from the first SLE symptoms to diagnosis was longer in EC patients, as were the follow-up periods. LAM patients exhibited higher prevalence rates of myositis, haemolytic anaemia and nephritis, but there were no differences in histological type or serositis. Anti-Sm, anti-Ro and anti-RNP antibodies were more frequently found in LAM patients. LAM patients also had higher levels of disease activity, severity and hospital admissions. However, there were no differences in damage index, mortality or co-morbidity index. In the multivariate analysis, after adjusting for confounders, in several models the odds ratio (95% confidence interval) for a Katz severity index >3 in LAM patients was 1.45 (1.038-2.026; p = 0.02). This difference did not extend to activity levels (i.e. SLEDAI >3; 0.98 (0.30-1.66)). CONCLUSION: SLE in Hispanic EC patients showed clinical differences compared to Hispanic LAM patients. The latter more frequently suffered nephritis and higher severity indices. This study shows that where lupus is concerned, not all Hispanics are equal.

Relationship between damage and mortality in juvenile-onset systemic lupus erythematosus: Cluster analyses in a large cohort from the Spanish Society of Rheumatology Lupus Registry (RELESSER).

OBJECTIVES: To identify patterns (clusters) of damage manifestation within a large cohort of juvenile SLE (jSLE) patients and evaluate their possible association with mortality. METHODS: This is a multicentre, descriptive, cross-sectional study of a cohort of 345 jSLE patients from the Spanish Society of Rheumatology Lupus Registry. Organ damage was ascertained using the Systemic Lupus International Collaborating Clinics Damage Index. Using cluster analysis, groups of patients with similar patterns of damage manifestation were identified and compared. RESULTS: Mean age (years) ±â€¯S.D. at diagnosis was 14.2 ±â€¯2.89; 88.7% were female and 93.4% were Caucasian. Mean SLICC/ACR DI ±â€¯S.D. was 1.27 ±â€¯1.63. A total of 12 (3.5%) patients died. Three damage clusters were identified: Cluster 1 (72.7% of patients) presented a lower number of individuals with damage (22.3% vs. 100% in Clusters 2 and 3, P < 0.001); Cluster 2 (14.5% of patients) was characterized by renal damage in 60% of patients, significantly more than Clusters 1 and 3 (P < 0.001), in addition to increased more ocular, cardiovascular and gonadal damage; Cluster 3 (12.7%) was the only group with musculoskeletal damage (100%), significantly higher than in Clusters 1 and 2 (P < 0.001). The overall mortality rate in Cluster 2 was 2.2 times higher than that in Cluster 3 and 5 times higher than that in Cluster 1 (P < 0.017 for both comparisons). CONCLUSIONS: In a large cohort of jSLE patients, renal and musculoskeletal damage manifestations were the two dominant forms of damage by which patients were sorted into clinically meaningful clusters. We found two clusters of jSLE with important clinical damage that were associated with higher rates of mortality, especially for the cluster of patients with predominant renal damage. Physicians should be particularly vigilant to the early prevention of damage in this subset of jSLE patients with kidney involvement.

Varón con neoplasia de pulmón metastatizada y síndrome paraneoplásico múltiple / Male with metastasized pulmonary carcinoma and multiple paraneoplastic syndrome

La osteoartropatía hipertrófica (OH) es un síndrome clínico en el que se desarrolla una periostitis crónica proliferativa de huesos largos, una deformación de los dedos de las manos y de los pies en palillo de tambor (dedos hipocráticos) y una sinovitis oligo o poliarticular. La forma secundaria generalizada se clasifica, etiopatogénicamente, en pulmonar, pleural, cardiovascular y gastrointestinal. La forma pulmonar se ha asociado al carcinoma broncogénico entre otras etiologías. Presentamos el caso de un síndrome paraneoplásico múltiple constituido por una OH, una crioglobulinemia mixta policlonal y una polineuropatía axonal en un paciente con un carcinoma broncogénico pulmonar con metástasis óseas. La excepcionalidad del caso está dada por la enfermedad paraneoplásica múltiple y metastásica asociadas. Revisamos la bibliografía al respecto y destacamos especialmente el singular patrón gammagráfico óseo constituido por una combinación de signos típicos de la OH y metástasis óseas (AU)
