We conducted a scoping review to synthesize evidence on the impact of biosimilar DMARDs on pregnancy outcomes. We searched Embase, MEDLINE and CENTRAL databases in November 2023 and June 2025. Inclusion criteria were studies examining biosimilar DMARD exposure for autoimmune diseases in mothers during pregnancy, fathers prior to conception and/or fetuses/neonates in-utero. Data were extracted on sample size, study design, drug exposure (timing, duration), and pregnancy outcomes. Patterns in methodologic reporting across studies were also analyzed. Overall, 6 studies (5 descriptive, 1 cohort study) were eligible for inclusion. Biosimilars examined were tumor necrosis factor inhibitors (infliximab, n = 4; etanercept, n = 2; adalimumab, n = 1) and B-cell inhibitors (rituximab, n = 1) among 63 mothers with inflammatory bowel disease, rheumatoid arthritis, or ankylosing spondylitis. Twenty-four fetal/neonatal (i.e., congenital anomaly), fetal/neonatal-maternal (i.e., Caesarean-section, spontaneous abortion), and maternal (i.e., disease flare) outcomes were reported. For methodologic reporting, we observed inconsistencies in exposure and outcome measures. To enhance comparability and standardization, we encourage the use of our Reproductive Health Outcomes Reporting Framework. Our scoping review is the first synthesis of perinatal evidence to date on biosimilar DMARDs.

Due to possibly progressive course of disease, both AS and MS may require biological treatment. Tumor necrosis alpha (TNF-alpha) inhibitors are a group of biologics approved for treatment of AS (e.g. adalimumab, certolizumab pegol, golimumab, infliximab, etanercept), and they are usually first choice of treatment when starting biological therapy. Another group of biologic agents approved for the treatment of AS are interleukin-17 (IL-17) inhibitors, such as secukinumab and ixekizumab. It is well established that TNF-alpha inhibitors increase the risk of demyelination, and are therefore contraindicated in patients with MS. Since the patient presented in this review was diagnosed with MS few years prior to the onset of AS symptoms, selecting an appropriate biologic therapy posed a clinical challenge due to the contraindication of TNF-alpha inhibitors in individuals with MS. After consulting with the treating neurologist, we initiated treatment of AS using the IL-17 inhibitor secukinumab. This decision was supported by evidence suggesting a significant role of IL-17 in the pathogenesis of MS, potentially offering a safer alternative to TNF-alpha inhibitors in this context. The selected therapy proved to be effective, leading to a notable reduction in overall pain and morning stiffness.

This cross-sectional study included 140 participants: 70 RA patients and 70 healthy controls. Forearm muscle thickness was measured ultrasonographically from the anterior forearm in radial and ulnar regions, and hand grip strength was assessed with a dynamometer. Pain was evaluated using the Visual Analog Scale (VAS), functional status with the Health Assessment Questionnaire (HAQ), hand function with the Duruoz Hand Index (DHI), and disease activity with the Disease Activity Score-28 (DAS28). Results: There were no significant differences in sociodemographic data between the groups (p > 0.05). Ulnar muscle thickness was significantly lower in the RA group than in the control group (3.13 ± 0.37 vs. 3.55 ± 0.33 cm) (p < 0.05). Radial muscle thickness was also reduced in RA patients compared to controls (1.69 ± 0.24 vs. 1.94 ± 0.30 cm) (p < 0.05). Hand grip strength was 20.66 ± 7.78 kg in RA patients and 27.06 ± 9.59 kg in controls. Both measures were negatively correlated with disease duration, HAQ, and DHI (p < 0.05). DAS28 showed a negative correlation with ulnar muscle thickness and handgrip strength (p < 0.05), but not with radial muscle thickness (p > 0.05). These findings demonstrate that forearm muscle thickness is reduced in RA patients and is strongly associated with handgrip strength, disease activity, and functional status.
