RESUMO
INTRODUCTION: A matching-adjusted indirect comparison (MAIC) was conducted to assess the relative efficacy at 52 weeks (Wk52) of bimekizumab 160 mg every 4 weeks (Q4W) and ustekinumab 45 or 90 mg every 12 weeks (Q12W) in patients with psoriatic arthritis (PsA) who were biologic disease-modifying anti-rheumatic drug naïve (bDMARD naïve) or who had a previous inadequate response or an intolerance to tumor necrosis factor inhibitors (TNFi-IR). METHODS: Relevant trials were systematically identified. Individual patient data from the bimekizumab trials BE OPTIMAL (NCT03895203; N = 431) and BE COMPLETE (NCT03896581; N = 267) were matched with summary data on patients receiving ustekinumab in the PSUMMIT 1 trial (NCT01009086; 45 mg, N = 205; 90 mg; N = 204) and a subgroup of TNFi-IR patients receiving ustekinumab in the PSUMMIT 2 trial (NCT01077362; 45 mg, N = 60; 90 mg, N = 58), respectively. Patients from the bimekizumab trials were re-weighted using propensity scores to match the baseline characteristics of the ustekinumab trial patients. Adjustment variables were selected based on expert consensus (n = 5) and adherence to established MAIC guidelines. Non-placebo-adjusted comparisons of recalculated bimekizumab and ustekinumab outcomes for the American College of Rheumatology (ACR) 20/50/70 response criteria (non-responder imputation) were analyzed. RESULTS: In patients who were bDMARD naïve, bimekizumab had a greater likelihood of response than ustekinumab at Wk52 for ACR20 (odds ratio [95% confidence interval] 45 mg: 2.14 [1.35, 3.40]; 90 mg: 1.98 [1.24, 3.16]), ACR50 (45 mg: 2.74 [1.75, 4.29]; 90 mg: 2.29 [1.48, 3.55]), and ACR70 (45 mg: 3.33 [2.04, 5.46]; 90 mg: 3.05 [1.89, 4.91]). In patients who were TNFi-IR, bimekizumab had a greater likelihood of response than ustekinumab at Wk52 for ACR20 (45 mg: 4.17 [2.13, 8.16]; 90 mg: 4.19 [2.07, 8.49]), ACR50 (45 mg: 5.00 [2.26, 11.05]; 90 mg: 3.86 [1.70, 8.79]), and ACR70 (45 mg: 9.85 [2.79, 34.79]; 90 mg: 6.29 [1.98, 20.04]). CONCLUSIONS: Using MAIC, bimekizumab showed greater efficacy than ustekinumab in achieving all ACR responses in patients with PsA who were bDMARD naïve and TNFi-IR at Wk52. TRIAL REGISTRATION: NCT03895203, NCT03896581, NCT01009086, NCT01077362.
RESUMO
OBJECTIVES: Hepatitis B reactivation (HBVr) constitutes a side effect of the treatment of autoimmune rheumatic diseases. Even though HBVr risk of conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs) and anti-tumor necrosis factor (anti-TNF) agents has long been established, the risk of targeted synthetic (ts)DMARDs and anti-interleukin (anti-IL) agents remains largely unknown. METHODS: We conducted a SLR (PubMed, Scopus and EMBASE) and metanalysis to examine the HBVr risk for the following: anti-IL17, anti-IL12/23, anti-IL23 and JAK-inhibitors in patients with chronic HBV infection (HBsAg presence or detectable HBV-DNA) and in patients with prior HBV infection (HBcAb-positive and HBsAg-negative). Meta-analysis was performed using both the fixed and random effects method and was conducted using the R computing language. RESULTS: Overall, our study revealed a low HBVr risk of < 6% in all agents; the risk was significantly higher for people having chronic compared with those with resolved HBV (14,4% vs 5.1%, respectively p< 0.01). There was no difference among different drugs in the HBVr rates [anti-IL-17: 4% (95% CI: 1-9%), anti-IL-12/IL-23: 2% (95% CI: 0-5%), JAK-inhibitors: 4% (95% CI: 1-8%), anti-IL23: 0%]. Of note, HBVr rate reached 28% in patients with chronic HBV who did not receive anti-viral treatment. For patients with resolved hepatitis the respective percentage was 4.7%. CONCLUSION: Overall, our meta-analysis shows that patients with chronic HBV receiving anti-IL-17, anti-IL-12/23, anti-IL-23 and JAK-inhibitors have significant risk for HBVr, especially if they are not under anti-viral treatment. In contrast, resolved HBV seems to offer minor risk for HBVr even without anti-viral treatment.
RESUMO
IBD (inflammatory bowel disease) is a chronic inflammatory disease of the gastrointestinal tract with increasing incidence worldwide. Multiple factors, such as genetic background, environmental and luminal factors, and mucosal immune dysregulation, have been implicated in the cause of IBD, although the cause of the disease remains unknown. IL-12 and IL-23 and their downstream signaling pathways participate in the pathogenesis of inflammatory bowel disease. Early and aggressive treatment with biologic therapies or novel small molecules is needed to decrease complications and the need for hospitalization and surgery. The landscape of inflammatory bowel disease (IBD) treatment has tremendously improved with the development of biologics and small molecule drugs. Several novel biologics and small molecule drugs targeting IL-12 and IL-23 and their downstream targets have shown positive efficacy and safety data in clinical trials, and several drugs have been approved for the treatment of IBD. In the future, numerous potential emerging therapeutic options for IBD treatment are believed to come to the fore, achieving disease cure.

BACKGROUND: Managing psoriasis and its comorbidities, particularly psoriatic arthritis, often involves using IL-23 and IL-12/23 inhibitors. However, the comparative risk of these treatments still needs to be explored. OBJECTIVE: This study evaluates the risk of developing psoriatic arthritis in patients treated with IL23 inhibitors compared to IL-12/23 inhibitors. METHODS: This retrospective cohort study utilized data from the TriNetX, including adult patients diagnosed with psoriasis. Patients with IL-23 or IL-12/23 inhibitors treatment were included and propensity score matched. The primary outcome was the incidence of arthropathic psoriasis, analyzed using a Cox regression hazard model and Kaplan-Meier estimates. RESULTS: The study included matched cohorts of patients treated with IL-23 inhibitors (n=2,273) and IL-12/23 inhibitors (n=2,995). Cox regression analysis revealed no significant difference in the cumulative incidence of arthropathic psoriasis between the IL-23i and IL-12/23i cohorts (p = 0.812). Kaplan-Meier estimates confirmed similar cumulative incidences of arthropathic psoriasis in both cohorts over the study period. LIMITATION: Long-term follow-up studies are required to understand more of the effects of these interleukin inhibitors. CONCLUSION: No significant difference but a numerically lower risk of PsA in PsO patients treated with IL-23 inhibitors than with IL-12/23 inhibitors, underscoring their comparable efficacy in PsO management and follow-up.
RESUMO
BACKGROUND & AIMS: Seventeen percent of patients with ulcerative colitis that undergo proctocolectomy with pouch surgery will develop chronic pouchitis. We evaluated the efficacy of ustekinumab for these patients. METHODS: We performed a prospective study of patients with chronic pouchitis receiving ustekinumab intravenously at baseline (â¼6 mg/kg) and 90 mg ustekinumab subcutaneously every 8 weeks thereafter. The Modified Pouchitis Disease Activity Index (mPDAI) was assessed at baseline and weeks 16 and 48. The primary endpoint was the proportion of patients achieving steroid-free remission (mPDAI <5 and reduction by ≥2 points) at week 16. Secondary endpoints included the proportion of patients achieving remission at week 48, the proportion of patients achieving response (reduction of mPDAI by ≥2 points) at weeks 16 and 48, and change in mPDAI. RESULTS: We enrolled 22 patients (59% male; median age, 42.2 years). Remission was achieved in 27.3% at week 16 and 36.4% at week 48. Response was achieved in 54.5% both at weeks 16 and 48. The median mPDAI decreased from 8 (interquartile range [IQR], 7-10) to 7 (IQR, 4-9) at week 16 (P = .007) and 4 (IQR, 1.75-7.25) at week 48 (P < .001). The clinical mPDAI subscore decreased from 3.5 (IQR, 2-4) to 2 (IQR, 1-3) at week 16 (P = .009) and 1 (IQR, 0-2.25) at week 48 (P = .001). The endoscopic mPDAI subscore decreased from 5.5 (IQR, 4-6) to 4 (IQR, 3-6) at week 16 (P = .032) and 3 (IQR, 1.75-4.25) at week 48 (P = .001). CONCLUSION: Ustekinumab was efficacious in one-half of the patients suffering from chronic pouchitis. Ustekinumab should therefore be positioned in the treatment algorithm of chronic pouchitis. (ClinicalTrials.gov Number NCT04089345).
RESUMO
Inflammatory bowel disease (IBD) is a chronic, recurrent gastrointestinal disorder with elusive etiology. Interleukin-12 (IL-12) and IL-23 have emerged as key proinflammatory mediators/cytokines in IBD pathogenesis. Ustekinumab (UST), targeting IL-12 and IL-23, has demonstrated promising efficacy and safety in the treatment of IBD. Recently, UST has become increasingly favored as a potential first-line treatment option. This review delineates UST's mechanism of action, its clinical applications in IBD, including the response rates, strategies for dose optimization for case of partial or lost response, and potential adverse events. This review aims to offer a comprehensive understanding of UST's role as a therapeutic option in IBD management.

OBJECTIVE: To describe the published efficacy and adverse event rates associated with existing biologics for the treatment of pityriasis rubra pilaris (PRP). DATA SOURCES: A literature review using the PubMed database (January 1990-July 2023) was conducted. Multiple search combinations were conducted using "pityriasis rubra pilaris" and various biologics as keywords to identify relevant articles. STUDY SELECTION AND DATA EXTRACTION: Inclusion criteria included all study types that were published within the past 30 years in English and mentioned at least one biologic and PRP. A preliminary search yielded a total of 499 results. After screening using inclusion and exclusion criteria, 77 relevant articles (69 case reports, 5 case series, 2 clinical trials, and 1 retrospective analysis) were analyzed. DATA SYNTHESIS: TNF-α inhibitors have been evaluated and are effective in treating PRP. However, recent treatment with anti-interleukin (IL)-17 and anti-IL-23 therapies such as ustekinumab, secukinumab, and ixekizumab are emerging as new treatment options with a mean improvement in PRP Area and Severity Index scores, change in severity of erythema, scaling, and thickness of PRP lesions. From initial clinical trials, secukinumab and ixekizumab are promising treatment options for achieving remission. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: This review compares the efficacy for numerous biologics and a discussion to guide clinicians on benefits and risks in choosing a biologic for PRP patients. CONCLUSIONS: Biologics may be a favourable treatment option leading to greater patient adherence due to reduced dosing frequencies, improvement in quality of life, and reduction in frequency and severity of flares.

BACKGROUND: Systemic immunomodulatory agents are indicated in the treatment of moderate-to-severe plaque psoriasis and psoriatic arthritis. Perioperative use of these medications may increase the risk of surgical site infection (SSI) and complication. OBJECTIVE: To evaluate the risk of SSI and complication in patients with chronic autoimmune inflammatory disease receiving immunomodulatory agents (tumor necrosis factor-alfa [TNF-α] inhibitors, interleukin [IL] 12/23 inhibitor, IL-17 inhibitors, IL-23 inhibitors, cytotoxic T-lymphocyte-associated antigen-4 costimulator, phosphodiesterase-4 inhibitor, Janus kinase inhibitors, tyrosine kinase 2 inhibitor, cyclosporine (CsA), and methotrexate [MTX]) undergoing surgery. METHODS: We performed a search of the MEDLINE PubMed database of patients with chronic autoimmune inflammatory disease on immune therapy undergoing surgery. RESULTS: We examined 48 new or previously unreviewed studies; the majority were retrospective studies in patients with rheumatoid arthritis and inflammatory bowel disease. CONCLUSION: For low-risk procedures, TNF-α inhibitors, IL-17 inhibitors, IL-23 inhibitors, ustekinumab, abatacept, MTX, CsA, and apremilast can safely be continued. For intermediate- and high-risk surgery, MTX, CsA, apremilast, abatacept, IL-17 inhibitors, IL-23 inhibitors, and ustekinumab are likely safe to continue; however, a case-by-case approach is advised. Acitretin can be continued for any surgery. There is insufficient evidence to make firm recommendations on tofacitinib, upadacitinib, and deucravacitinib.

BACKGROUND & AIMS: Dysbiosis of the gut microbiota is considered a key contributor to inflammatory bowel disease (IBD) etiology. Here, we investigated potential associations between microbiota composition and the outcomes to biological therapies. METHODS: The study prospectively recruited 296 patients with active IBD (203 with Crohn's disease, 93 with ulcerative colitis) initiating biological therapy. Quantitative microbiome profiles of pretreatment and posttreatment fecal samples were obtained combining flow cytometry with 16S amplicon sequencing. Therapeutic response was assessed by endoscopy, patient-reported outcomes, and changes in fecal calprotectin. The effect of therapy on microbiome variation was evaluated using constrained ordination methods. Prediction of therapy outcome was performed using logistic regression with 5-fold cross-validation. RESULTS: At baseline, 65.9% of patients carried the dysbiotic Bacteroides2 (Bact2) enterotype, with a significantly higher prevalence among patients with ileal involvement (76.8%). Microbiome variation was associated with the choice of biological therapy rather than with therapeutic outcome. Only anti-tumor necrosis factor-α treatment resulted in a microbiome shift away from Bact2, concomitant with an increase in microbial load and butyrogen abundances and a decrease in potentially opportunistic Veillonella. Remission rates for patients hosting Bact2 at baseline were significantly higher with anti-tumor necrosis factor-α than with vedolizumab (65.1% vs 35.2%). A prediction model, based on anthropometrics and clinical data, stool features (microbial load, moisture, and calprotectin), and Bact2 detection predicted treatment outcome with 73.9% accuracy for specific biological therapies. CONCLUSION: Fecal characterization based on microbial load, moisture content, calprotectin concentration, and enterotyping may aid in the therapeutic choice of biological therapy in IBD.

Introduction: A growing number of randomized controlled trials (RCTs) have demonstrated the effectiveness of interleukin (IL)-23 and IL-12/23 inhibitors in treating Crohn's disease (CD). This study evaluated the efficacy of IL-23 and IL-12/23 inhibitors in the induction phase for the treatment of CD. Material and methods: We searched the following databases from inception until December, 2022: Medline, Embase, Web of Science and the Cochrane Library. The primary outcome was the proportion of CD patients who achieved clinical remission at the end of the induction therapy period. Secondary outcomes included clinical response, endoscopic remission, endoscopic response and normalized C-reactive protein (CRP). Results: After screening, 7 RCTs were included in our study. The meta-analysis showed that, in the induction period, more patients treated with IL-23 inhibitors and IL-12/23 inhibitors achieved clinical remission than patients with placebo therapy (RR = 2.11, 95% CI: 1.83-2.44; RR = 1.94, 95% CI: 1.64-2.29; respectively). The IL-23 inhibitor group and the IL-12/23 inhibitor group showed higher clinical response rates than the placebo group (RR = 1.92, 95% CI: 1.74-2,11; RR = 1.83, 95% CI: 1.61-2.09; respectively). In addition, the IL-23 inhibitor group had a higher endoscopic remission rate and endoscopic response rate than the placebo group; the corresponding pooled RRs were 3.40 (95% CI: 2.57-4.50) and 2.65 (95% CI: 2.65-3.12), respectively. Conclusions: IL-23 and IL-12/23 inhibitors were efficient methods in the induction treatment of CD.
RESUMO
Acne fulminans (AF) is a rare disorder marked by severe eruptions of inflamed nodules, hemorrhagic crusts, and ulcers accompanied by systemic symptoms and often laboratory abnormalities. Commonly affecting adolescent males with pre-existing acne, AF has been associated with isotretinoin therapy and elevated testosterone levels. With unknown pathogenesis, lesions frequently involve the trunk and face and are managed standardly with corticosteroids and isotretinoin. Uncontrolled or recurrent cases pose challenges due to prolonged high-dose corticosteroid use with increased scarring. In this study, we present a case of AF in a 17-year-old male unresponsive to corticosteroid and isotretinoin therapy, successfully treated with ustekinumab, an interleukin (IL)-12/23 inhibitor. The introduction of ustekinumab facilitated a controlled corticosteroid taper and isotretinoin dose escalation, resulting in significant clinical improvement of skin lesions and systemic symptoms. This case report underscores the potential of ustekinumab as a viable therapeutic option in the treatment of AF, particularly in cases where corticosteroid and isotretinoin combination therapy have proven ineffective.
RESUMO
Monoclonal antibodies or fusion proteins, defined as biological drugs, have modified the natural history of numerous immune-mediated disorders, allowing the development of therapies aimed at blocking the pathophysiological pathways of the disease, providing greater efficacy and safety than conventional treatment strategies. Virtually all therapeutic proteins elicit an immune response, producing anti-drug antibodies (ADAs) against hypervariable regions of immunoglobulins. Immunogenicity against biological drugs can alter their pharmacokinetic and pharmacodynamic properties, thereby reducing the efficacy of these drugs. In more severe cases, ADAs can neutralize the therapeutic effects of the drug or cause serious adverse effects, mainly hypersensitivity reactions. The prevalence of ADAs varies widely depending on the type of test used, occurrence of false-negative results, and non-specific binding to the drug, making it difficult to accurately assess their clinical impact. Concomitant use of immunosuppressors efficiently reduces the immunogenicity in a dose-dependent manner, either by decreasing the frequency of detectable ADAs or by delaying their appearance, thereby enhancing the effectiveness of biological therapies. Among the new therapeutic strategies for the management of psoriasis, biological agents have gained increasing importance in recent years as they interrupt key inflammation pathways involved in the physiopathology of the disease. Reports regarding ADA in new biologics are still scarce, but the most recent evidence tends to show little impact on the clinical response to the drug, even with prolonged treatment. It is therefore essential to standardize laboratory tests to determine the presence and titles of ADAs to establish their administration and management guidelines that allow the determination of the real clinical impact of these drugs.

BACKGROUND: Psoriasis is a common chronic inflammatory skin disease with a strong genetic basis. Cytokines such as tumor necrosis factor alpha (TNF-alpha), interleukins (ILs) such are IL-12 and IL-23, and interferon gamma (IFN-gamma) are released from various inflammatory and resident cells, and have been implicated in the initiation/maintenance of inflammation. Certain alleles of the aforementioned cytokines may be associated with disease susceptibility/severity. OBJECTIVE: To investigate the association of three common functional gene polymorphisms, namely TNF -308 G/A (rs1800629), IL12B (encoding the p40 subunit of IL-12/23) +1188 A/C (rs3212227), and IFNG +874 T/A (rs2430561) with psoriasis development and severity in Serbian patients. METHODS: We genotyped 130 patients with psoriasis (26 of whom also had psoriatic arthritis) and 259 controls; rs1800629 and rs3212227, and rs2430561, by real-time PCR assay. RESULTS: The TNF GG genotype was detected at a higher frequency in patients with psoriasis compared to control subjects (OR, 1.420; 95% CI, 0.870~2.403) without statistical significance (p=0.191). Lack of the TNF G allele was associated with lower psoriasis severity (p=0.007). The IL12B AC genotype was underrepresented in the patients with psoriatic arthritis compared to healthy subjects (OR, 0.308; 95% CI, 0.090~1.057; p=0.049). The distribution of the rs2430561 allele and genotype frequencies was similar between patients with psoriasis and controls. CONCLUSION: Our study demonstrates an effect of the rs1800629 on psoriasis severity, and a marginal impact of the rs3212227 on susceptibility to psoriatic arthritis. Collectively, our results obtained in a Serbian cohort expand current knowledge regarding individual predisposition to psoriatic disease.
