  • Etanercept (ETN) was studied in a real-world setting to evaluate its effects on radiographic progression in patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA) over a treatment period of up to 36 months in Germany.
  • The study involved 1821 patients and found that the mean modified total Sharp score (mTSS) remained stable during treatment, indicating less radiographic progression compared to the pre-treatment phase, especially in patients with prior radiographic data.
  • Overall, the findings suggest that ETN slows radiographic progression in RA and PsA, as demonstrated by a higher rate of non-progression during treatment and improvements in clinical disease activity and patient

Article Abstract

Introduction: Etanercept (ETN) has been shown to slow radiographic progression of rheumatoid arthritis (RA) and psoriatic arthritis (PsA) in clinical trials. This real-world, non-interventional study assessed radiographic progression in patients with RA or PsA treated with ETN for ≤ 36 months in outpatient care in Germany (NCT01623752).

Methods: Patients with RA or PsA attended ≤ 10 visits across two study phases (phase 1: seven visits, baseline to month 18; phase 2: three visits until month 36). Radiographs were taken at baseline (Rx1), months 12-18 (Rx2), and/or months 30-36 (Rx3). Historic radiographs (Rx0) taken 12-48 months pre-baseline were also evaluated (if available). The primary endpoint was the change in modified total Sharp score (mTSS). The erosion score (ES) and joint space narrowing score (JSN) were also evaluated.

Results: Overall, 1821 patients were enrolled (RA: n = 1378; PsA: n = 440). In patients with Rx1 and Rx2 (RA: n = 511; PsA: n = 167), the mean mTSS remained stable for both disease groups, and the annualized median change in mTSS was 0. In patients with Rx0, Rx1, and Rx2 (RA: n = 180; PsA: n = 47), annualized radiographic progression in mTSS, ES, and JSN was larger in the pre-ETN treatment phase than during ETN treatment in both disease groups. The percentage of patients with radiographic non-progression was higher during ETN treatment versus pre-ETN. Improvement in clinical disease activity and patient-reported outcomes was also observed.

Conclusions: This was the first real-world, non-interventional study to report systematically collected radiographic data in a large cohort of patients with RA or PsA under treatment with a biologic. In patients with available radiographic data, mean radiographic progression was lower and the proportion of patients without progression was greater during ETN treatment than in the pre-ETN period.

Fibrous dysplasia is a slow-progressing benign condition characterized by abnormal bone formation that leads to some skeletal disorders. Although some of the fibrous dysplasia have unusual clinical and radiographic features that can lead to a challenging diagnosis, most lesions reveal an expansile bone defect due to cortex thinning. This report presented a case of monostotic fibrous dysplasia of a 43-year-old woman with involvement of the right maxillary jaw and sinuses, which indicated unusual histopathological features.

Lemierre's syndrome is a rare and potentially life-threatening complication of head and neck infections, such as bacterial pharyngitis or tonsillitis. It is characterized by the extension of infection into the lateral pharyngeal spaces, leading to subsequent septic thrombophlebitis of the internal jugular vein(s). Although relatively uncommon since the advent of appropriate antibiotic therapy, the incidence of Lemierre's syndrome has increased in the past 15 years, especially among young, healthy adults.

Introduction: SPLASH (NCT04647526) is a multicenter phase III trial evaluating the efficacy and safety of [Lu]Lu-PNT2002 radioligand therapy in metastatic castration-resistant prostate cancer (mCRPC). This study leveraged a lead-in phase to assess tissue dosimetry and evaluate preliminary safety and efficacy, prior to expansion into a randomized phase. Here we report those results.

Osteonecrosis of femoral head (ONFH) can be a debilitating disease, for which numerous salvage surgeries have been popularized to halt its progression. The aim of this study was to assess the clinical and radiological outcomes of a single-incision core decompression (CD) technique using trochanteric autograft in ONFH and to determine the prognostic factors of treatment success. Sixty-six hips (41 patients) of Association Research Circulation (ARCO) 1 and 2 ONFH undergoing CD were included in the study with a mean follow-up of 58 months.
