Abstract
Biologic medications have revolutionized treatment of psoriasis; however, there remains uncertainty in which medications should be used to maximize efficacy based on race/ethnicity. The purpose was to determine if efficacy of biological medications differs based on race/ethnicity. A systematic review identified all clinical trials focused on biologic treatment outcomes from inception of database until March 5th, 2021. Included studies provided data on racial/ethnic differences in biologic skin clearance efficacy using the Psoriasis Area and Severity Index (PASI) and "clear/almost clear" scores. There were 1220 studies identified, and 24 included in the review. The races/ethnicities included were Asian (n = 2740), White (n = 9745), Black (n = 138), and Latino (n = 728). Ixekizumab provided the highest "clear/almost clear" score (90.7%, 89.4%) and PASI 75 (98.8%, 96.6%) for Asian and Latino patients, respectively. Guselkumab had the highest "clear/almost clear" score for White (86.8%) patients, while Black patients had highest "clear/almost clear" (75.0%) and PASI 75 (91.7%) scores to brodalumab. Limitations included lack of studies reporting outcome data based on race/ethnicity and lack of patients of color within psoriasis clinical trials. For treatment of plaque psoriasis, there is evidence of differences in efficacy of biologics improving clinical disease severity between different races or ethnicities.

Abstract
Numerous
post-translational modifications (PTMs) govern the collective metabolism of a cell through altering the structure and functions of proteins. The action of the most prevalent PTMs, encompassing phosphorylation, methylation, acylations, ubiquitination and glycosylation is well documented. A less explored protein PTM, conversion of peptidylarginine to citrulline, is the subject of this review. The process of citrullination is catalysed by peptidylarginine deiminases (PADs), a family of conserved enzymes expressed in a variety of human tissues. Accumulating evidence suggest that citrullination plays a significant role in regulating cellular metabolism and gene expression by affecting a multitude of pathways and modulating the chromatin status. Here, we will discuss the biochemical nature of arginine citrullination, the enzymatic machinery behind it and also provide information on the pathological consequences of citrullination in the development of inflammatory diseases (rheumatoid arthritis, multiple sclerosis, psoriasis, systemic lupus erythematosus, periodontitis and COVID-19), cancer and thromboembolism. Finally, developments on inhibitors against protein citrullination and recent clinical trials providing a promising therapeutic approach to inflammatory disease by targeting citrullination are discussed.

Abstract
AIM The efficacy and safety of golimumab + methotrexate (MTX) were evaluated in Chinese patients with active rheumatoid arthritis (RA) despite MTX therapy. METHODS Chinese patients (n = 264) were randomly assigned (1 : 1) to receive subcutaneous injections of placebo + MTX with crossover to golimumab 50 mg + MTX at week 24 (Group 1) or to golimumab 50 mg + MTX (Group 2) every 4 weeks. Group 1 patients with inadequate response entered blinded early escape to golimumab 50 mg + MTX at week 16. At least a 20% improvement in the American College of Rheumatology (ACR20) criteria at week 14 was the primary endpoint. Other assessments included the 28-joint count Disease Activity Score using C-reactive protein (DAS28-CRP) and Health Assessment Questionnaire-Disability Index (HAQ-DI) through week 52. Adverse events (AEs) were monitored through week 56. RESULTS ACR20 response at week 14 was significantly higher in Group 2 (40.9% [54/132]) compared with Group 1 (15.9% [21/132]; P < 0.001). Greater proportions of patients in Group 2 compared with Group 1 had a DAS28-CRP response at week 14 (65.2% vs. 30.3%, P < 0.001) or ACR20 response at week 24 (42.4% vs. 15.9%, P < 0.001), and Group 2 had a significantly greater change in HAQ-DI at week 24 (-0.26 vs. 0.15, P < 0.001). After week 24, the proportion of patients achieving ACR20 in Group 1 approached that in Group 2. Through week 16, 23.5% of Group 1 and 26.7% of Group 2 patients reported AEs. Among golimumab + MTX-treated patients, 50.2% and 4.2% had ≥ 1 AE or serious AE, respectively, through week 56. No unexpected safety signals were observed. CONCLUSION Among MTX-experienced Chinese patients with active RA, a significantly greater proportion of patients receiving golimumab + MTX had improvements in the signs and symptoms of RA compared with MTX monotherapy. Safety findings were consistent with previous studies of golimumab in patients with RA.

Better short-term clinical response to etanercept in Chinese than Caucasian patients with active ankylosing spondylitis. Mod Rheumatol 2010; 20:580-7. [PMID: 20683633 DOI: 10.1007/s10165-010-0334-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2010] [Accepted: 05/28/2010] [Indexed: 10/19/2022]
Abstract
Tumor necrosis factor-alpha (TNF-α) inhibitors including etanercept have been demonstrated to be very effective in severe ankylosing spondylitis (AS) in Caucasian patients. However, clinical efficacy of etanercept to treat active AS in Chinese patients has not been reported. In this study, a prospective, open-label trial of etanercept (25 mg BIW), involving 46 AS patients from 16 medical centers of Taiwan, was conducted. Questionnaire was utilized to record demographic data and clinical parameters, including Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), Bath AS Global Index (BASGI), Assessment in Ankylosing Spondylitis (ASAS) 20, 50, and 70, and others, before and at different time intervals after etanercept treatment. Laboratory tests including blood chemistry, hematology, urine analysis, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were done at baseline and at weeks 4, 8, and 12. In this 12-week study, etanercept demonstrated rapid and significant improvement in the ASAS20 response criteria (91.3%), at as early as 2 weeks of therapy (71.3%). Partial remission of AS was achieved in 49.3% of patients after 12 weeks of treatment. Disease activity (BASDAI) and function (BASFI) were also significantly improved after 12 weeks etanercept treatment (p < 0.0001 and p < 0.0001, respectively). In addition, significant increase of chest expansion (2.77 ± 1.69 cm versus 3.56 ± 1.82 cm, p = 0.0004) and lumbar flexion (2.11 ± 2.76 cm versus 2.58 ± 3.42 cm, p = 0.0075) and significant reduction of occiput-to-wall distance (6.59 ± 7.14 cm versus 5.32 ± 6.65 cm, p = 0.0006) were also demonstrated. Both ESR and CRP declined significantly after patients were treated with etanercept. There were no severe adverse effects during the treatment period. Etanercept is generally safe, well tolerated, and effective in Chinese patients with severe AS. Clinical efficacy, including partial remission and BASDAI, is even better in Chinese than in Caucasian patients. Further study is required to assess long-term efficacy and safety in Chinese patients with AS.

Abstract
STUDY DESIGN Immunohistological and behavioral analysis of the effect of a tumor necrosis factor alpha (TNF-alpha) inhibitor in an injured-nerve model. OBJECTIVE To examine the effect of direct application of a TNF-alpha inhibitor (etanercept) on injured-nerve pain caused by nucleus pulposus. SUMMARY AND BACKGROUND DATA TNF-alpha is thought to play a crucial role in radicular pain. Calcitonin gene-related peptide (CGRP) is an inflammatory neuropeptide found in small sensory neurons. We have reported that CGRP appears in medium and large dorsal root ganglion (DRG) neurons that transmit proprioception in physiologic conditions. The purpose of the current study was to examine the change in behavior and phenotypic change of CGRP-immunoreactive DRG neurons by the TNF-alpha inhibitor, etanercept, in a disc herniation model. METHODS For the injured-nerve model, nucleus pulposus was applied to the sciatic nerve and the sciatic nerve pinched. Saline (10 microL; n = 10), as a control, or etanercept (150 microg: n = 10) were applied to sciatic nerves simultaneously. Mechanical allodynia was examined. Immunohistochemistry was used to examine CGRP expression in L5 DRGs. RESULTS Significant mechanical allodynia for 10 days was seen in the injured-nerve group compared with sham-operated animals. Etanercept ameliorated the mechanical allodynia slightly on day 2; however, there was no effect on other days. CGRP immunoreactivity was upregulated in the L5 DRG neurons of injured-nerve groups compared with the sham-operated group (P < 0.01). However, etanercept did not affect CGRP expression after nerve injury (P > 0.05). Proportions of CGRP- immunoreactive medium and large neurons were not significantly different in the nerve injury + saline group compared with the injury + etanercept group (P > 0.05). CONCLUSION Our results indicate that direct application of a TNF-alpha inhibitor had a small effect on acute pain behavior and may not be effective for suppression of inflammatory peptides in the current disc-herniation model.
