RESUMEN
Introduction: Crohn's disease (CD) is a chronic, progressive inflammatory bowel disorder characterized by persistent inflammation and noncontiguous "skip lesions" throughout the gastrointestinal tract. With a prevalence of 100-300 cases per 100,000 individuals, CD is most common in Western Europe and North America. Symptoms include abdominal pain, diarrhea, fever, weight loss, and anemia, with severe cases leading to complications such as perianal abscesses and cutaneous fistulas. Treatment involves pharmaceutical interventions, bowel rest, and sometimes surgery, with biological therapies like ustekinumab and mirikizumab gaining prominence. Clinical Trials: The VIVID-1 trial assessed mirikizumab in patients with moderately to severely active CD. By Week 12, mirikizumab significantly outperformed placebo in clinical response (45.4% vs. 19.6%, p < 0.000001). By Week 52, it showed higher clinical remission rates (54.1% vs. 19.6%) and demonstrated non-inferiority to ustekinumab in clinical remission (p = 0.51). The SEQUENCE study compared risankizumab to ustekinumab, with risankizumab showing superior reductions in inflammatory markers and higher biologic remission rates at Weeks 8, 24, and 48. Both treatments had similar safety profiles, with common adverse events including COVID-19, anemia, and headache. Conclusion: Mirikizumab, based on the VIVID-1 trial outcomes, is a promising addition to CD therapy. It demonstrated significant clinical responses and remission rates, warranting further research on its long-term efficacy and safety. Updating professional guidelines and addressing affordability will ensure broader access and improved management of CD.
RESUMEN
BACKGROUND: The relationship between biologic treatments for psoriasis (PsO) and development of inflammatory arthritis in patients is not fully understood. OBJECTIVE: Analyze the effects of biologic treatment on development of inflammatory arthritis in PsO patients. METHODS: This retrospective study assessed PsO patients identified in the Optum Clinformatics® Data Mart database from Jan 2007 to Mar 2023 with no baseline diagnosis of inflammatory arthritis. Patients were stratified based on the class of initial biologic treatment (IL-23, IL-12/23, IL-17, or TNF inhibitor) and followed for up to 3 years or development of inflammatory arthritis. Risk of developing inflammatory arthritis was assessed using a multivariate Cox proportional hazard models using IL-23 inhibitors as reference. RESULTS: Incidence rates of developing inflammatory arthritis expressed as events/100 person-years were 4.99, 7.29, 6.06, and 9.39 for IL-23, IL-17, IL-12/23, and TNF inhibitors respectively. Adjusted hazard ratios were significantly higher for patients receiving IL-17 (1.44; p=.0294) and TNF (1.90; p<.0001) inhibitors when compared to patients receiving IL-23 inhibitors. LIMITATIONS: Limitations include those associated with medical coding errors and the potential for protopathic bias. CONCLUSION: Patients receiving IL-23 inhibitors are at lower risk for developing inflammatory arthritis or PsA compared to those receiving IL-17 and TNF inhibitors.
RESUMEN
BACKGROUND: The recent introduction of biological drugs specifically targeting the interleukins involved in psoriasis pathogenesis revolutionized the therapeutic scenario of moderate to severe forms of psoriasis. Among these, risankizumab, an anti-IL-23, was shown to be effective both in clinical trials and real-life experiences. However, data on its use on very severe forms of psoriasis, defined by a Psoriasis Area Severity Index (PASI) of at least 30, are scant. In this context, our study aimed to investigate the outcomes of patients with very severe psoriasis, and the involvement of difficult-to-treat areas treated with risankizumab for up to 2 years. METHODS: A retrospective, observational study enrolled patients with very severe plaque psoriasis and the involvement of difficult-to-treat areas undergoing treatment with risankizumab. Clinical and demographic data were collected at baseline. Moreover, at baseline and each dermatological examination (16, 28, 40 and 104 weeks), clinical improvement was measured using the percentage of patients achieving PASI 75/90/100 response, site-specific Psoriasis Global Assessment and Dermatology Life Quality Index. RESULTS: At baseline, the mean PASI was 35.1 ± 5.1. A significant reduction was observed since week 16 and maintained up to week 104. Moreover, the Psoriasis Global Assessment and Dermatology Life Quality Index improved as well. CONCLUSIONS: Risankizumab showed to be effective and safe in patients affected by very severe forms of psoriasis with the involvement of difficult-to-treat areas.

Risankizumab is a humanized monoclonal antibody that inhibits the p19 subunit of IL-23 cytokine. Recently it has been approved for the treatment of patients with moderate-to-severe Crohn's disease (CD). We conducted a scoping review to summarize the available data on risankizumab and to define its positioning in the treatment algorithm of CD. Pubmed, Embase and Scopus databases were searched up to Oct 31, 2023 to identify studies reporting efficacy and safety data of risankizumab in patients with CD. Risankizumab is an effective and safe drug for the management of patients with moderate-to-severe CD. It could be used as first-line therapy in biologic-naive patients and in patients who have previously failed other biological therapies.
When we eat the food is processed and absorbed by the gastrointestinal tract. Sometimes, in some people, the gastrointestinal tract gets inflamed, causing problems like tummy ache and diarrhea: this condition is called Crohn's disease. To help turn off this inflammation and make people with Crohn's disease feel better, there's a new treatment called risankizumab. Risankizumab binds to the proteins in the body that cause inflammation and blocks their effects. This helps to reduce gastrointestinal inflammation and relieve its symptoms. Scientific studies have shown that is effective, safe, and it starts working quickly. Patients using this treatment do not have to go to the hospital every time. After three times in the outpatient's clinic, they can continue the treatment comfortably at home using a small device that sticks to the body and administers the medicine.

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: Although clinical trials and real-world data suggest that the risk of COVID-19 and its complications is not exacerbated in patients with psoriasis treated by biological agents, the evidence for this is still limited. Objectives: We aimed to assess the outcomes of COVID-19 among Chinese patients with psoriasis treated by IL-23 inhibitor, and to compare these variables in patients receiving other therapies. Methods: A cross-sectional cohort study was conducted to compare psoriasis treatment with IL-23 inhibitor to other treatment methods. All the patients received a questionnaire that contained questions about their psoriasis treatment, COVID-19 symptoms, and related risk factors. The prevalence of COVID-19 was calculated, and logistic regression analyses were performed to determine the association between treatment method and COVID-19 risk. The symptoms of COVID-19 and long COVID were described for each treatment group. Results: Between December 2022 and February 2023, 732 patients with psoriasis were included in the final analysis. 549 patients had a SARS-CoV-2 infection during the study period. Our results showed that individuals who worked outdoors had a decreased risk of COVID-19, as did those who had other allergic disease. With regard to the effect of the treatment regimens, IL-23 inhibitor treatment was associated with a decreased risk of COVID-19 compared to almost all the other treatments except acitretin. Fever was the most common symptom, but the maximum temperature and duration of fever were comparable among the treatment groups. Patients treated with IL-23 inhibitor were more likely to be asymptomatic after recovery compared to patients treated with methotrexate, narrow-bound ultra violet B, or TNF-α inhibitor. Conclusions: IL-23 inhibitor treatment may lower the risk of COVID-19 and long COVID. Thus, IL-23 inhibitor treatment might be beneficial and positively considered for patients with psoriasis who require systemic treatment during periods when there is a surge in COVID-19 cases.
RESUMEN
BACKGROUND: Paradoxical psoriasis (PP) has been mainly described in patients receiving tumor necrosis factor-α (TNFα) inhibitors for inflammatory bowel disease or psoriasis vulgaris, while such data in the context of hidradenitis suppurativa (HS) are scarce. The purpose of this study was to demonstrate the course of PP and the underlying HS upon switching from adalimumab to a biologic agent targeting the interleukin (IL)-17/IL-23 axis. METHODS: The electronic medical database of the outpatient department for HS of a tertiary hospital for skin diseases was searched to identify patients with moderate-to-severe HS under treatment with adalimumab, who developed PP and were switched to biological therapy with an IL-17 or IL-23 inhibitor between February 2016 and January 2022. Disease assessment scores were evaluated at baseline, at time of PP development, as well as six and 12 months thereafter. RESULTS: Among the 83 patients who received adalimumab for the treatment of HS between February 2016 and January 2022, 10 patients (12%) developed paradoxical psoriasiform skin reactions after a median time of seven (range, 2-48) months. There were four females (40%) and six males (60%) with a median age of 42.5 (range, 33-56) years. Five patients presented with plaque psoriasis and five with palmoplantar pustulosis, while four had intertriginous and three nail involvement. In most of the patients, HS responded well to adalimumab at onset of PP. Eight patients were changed to secukinumab, one to ustekinumab, and one to risankizumab. HS further improved in all but 2 patients, one receiving secukinumab and one receiving risankizumab. In addition, all patients achieved improvement of PP. CONCLUSION: Despite the small number of patients, this study provides support that patients with adalimumab-induced PP may benefit from biologics targeting the IL-17/IL-23 axis. Further studies are needed to establish the optimal therapeutic strategy of the anti-TNFα-induced PP in the context of HS.

Rituximab and prednisone are commonly used treatments for autoimmune hemolytic anemia (AIHA), where the body's immune system attacks and destroys its red blood cells. However, some AIHA patients may become refractory to rituximab treatment, and this can result in continued hemolysis and persistent anemia, making it challenging for affected individuals to manage their symptoms. The underlying causes of rituximab refractoriness in AIHA patients can be complex and vary from patient to patient. Herein, we present a case of newly diagnosed warm and cold AIHA that remained in remission with an interleukin-23 inhibitor.

BACKGROUND: Medications used in the treatment of dermatologic conditions have been associated with squamous cell carcinoma (SCC), basal cell carcinoma (BCC), melanoma, and Merkel cell carcinoma (MCC). OBJECTIVE: The objective of the study was to examine the relationship between systemic dermatologic medications and skin cancer in the FDA Adverse Event Reporting System (FAERS). METHODS: Case-control analyses were performed in FAERS from 1968 to 2021 to examine the reporting odds ratios (RORs) for SCC, BCC, melanoma, and MCC. RESULTS: The oral immunosuppressants were all associated with increased ROR of SCC, BCC, melanoma, and MCC. Azathioprine had the highest ROR for SCC (34.13, 95% CI 29.07-40.08), BCC (21.15, 95% CI 20.63-25.98), and MCC (44.76, 95% CI 31.52-63.55), while quinacrine and guselkumab had the highest ROR for melanoma (13.14, 95% CI 1.84-93.89 vs. 12.73, 95% CI 10.60-15.30, respectively). The TNF-α inhibitors were associated with an increased ROR for all skin cancers investigated. CONCLUSIONS: The oral immunosuppressants and many biologic medications were associated with an increased ROR of skin cancers including TNF-α inhibitors (etanercept, adalimumab, infliximab), IL-23 or IL-12/23 inhibitors (ustekinumab, risankizumab), and the CD-20 inhibitor rituximab but not dupilumab or IL-17 inhibitors.

Although targeted immunomodulatory medications are increasingly utilized for inflammatory skin conditions like plaque psoriasis, little is known of the trends in the adoption of newly Federal Drug Administration (FDA)-approved immunomodulators by dermatologists. We performed a retrospective, cross-sectional analysis of Medicare Part D Prescriber datasets to identify dermatologists filing Medicare prescription claims for immunomodulatory drugs FDA-approved for plaque psoriasis between 2013 and 2018. Differences in dermatologist characteristics were determined between dermatologists prescribing a psoriasis treatment within two years of its FDA approval, "early adopters" and non-prescriber dermatologists over the same time period. Biologics approved for psoriasis from 2013 to 2018 included certolizumab pegol, secukinumab, brodalumab, ixekizumab, guselkumab, and apremilast. Early adopter dermatologists (n = 783) accounted for 5% of all Medicare Part D prescribing dermatologists. Early adopters were more likely to be male, in practice longer, and had a greater number of average annual beneficiaries than dermatologists who did not. Only six (< 1%) early adopters practiced in a small town or rural areas. We believe these data show that the adoption of novel biologic treatments for psoriasis by dermatologists to Medicare beneficiaries may be associated with clinician experience and practice volume. Additionally, we identified low absolute numbers of dermatologists prescribing biologics overall in non-metropolitan areas, which may represent delayed access to novel psoriasis treatments for many Medicare beneficiaries.

Objective: This study aimed to investigate the clinical features of biologics-induced bullous pemphigoid (BP) and the therapeutic effects of those agents for BP, exploring the underlying pathophysiological mechanisms. Methods: We searched PubMed, Web of Science, and Elsevier for studies involving pemphigoid patients treated with or induced by identical biologics published in English from January 2009 to April 2022. Results: Seventeen cases of drug-induced BP associated with anti-tumor necrosis factor (aTNF)-α therapies, one with interleukin (IL)-17 inhibitors, and seven with IL-12/IL-23 or IL-23 inhibitors were enrolled. Time to cutaneous toxicity varied among different types of agents, and the characteristics of clinical examinations were similar to idiopathic BP. Discontinuation of the culprit drugs and initiation of topical or systemic corticosteroids were adequate in most cases. Several monoclonal antibodies above have also been reported for the treatment of refractory or recurrent BP, especially concurrent with psoriasis. Conclusion: Biologics for immune-related diseases, including TNF-α, IL-17, and IL-12/IL-23 or IL-23 inhibitors, can both induce and treat BP, which might be associated with a helper T cells Th1/Th2 imbalance, complicated inflammatory networks, and a specific individual microenvironment, suggestive of a new perspective on the therapeutic algorithms of BP. There have been numerous reports about biologics inducing or treating BP. We have taken note of this phenomenon and focused on biologics with both pathogenetic and therapeutic effects on BP. Our review summarized the clinical characteristics of associated cases, trying to figure out the underlying mechanisms of this paradoxical phenomenon and to provide an integrated perspective and new therapeutic alternatives for BP.

BACKGROUND: Antibody-based therapies that inhibit proinflammatory cytokine signaling are commonly used in dermatology. Paradoxically, these medications may induce or exacerbate inflammatory disorders. OBJECTIVE: To summarize the spectrum of manifestations, incidence, timing, potential mechanisms of, and general management approaches to paradoxical cutaneous reactions induced by cytokine-targeted antibodies in dermatology. METHODS: We performed a systematic review and analysis of published cases of cutaneous paradoxical reactions (PRs) reported in association with tumor necrosis factor α, interleukin (IL) 12/23 (p40), IL-17A/17R, IL-23 (p19), and IL-4Rα inhibitors. RESULTS: We identified 313 articles reporting 2049 cases of PRs. Tumor necrosis factor α inhibitors resulted in 91.2% (1869/2049) of all cases, followed by IL-17/17R (3.5%), IL-4Rα (2.7%), IL-12/23 (2.4%), and IL-23 (0.01%) inhibitors. Psoriasiform and eczematous eruptions were the most commonly reported, but a wide spectrum of patterns were described. Phenotypically overlapping reaction patterns were common. Time to onset typically ranged from weeks to months but could occur more than a year later. Improvement or resolution upon discontinuation of the inciting drug was common. LIMITATIONS: This was a retrospective analysis. CONCLUSIONS: Familiarity with the clinical features of PRs from cytokine-blocking antibodies may facilitate efficient recognition and management.

Little is known about how psoriatic disease characteristics and treatment outcomes differ geographically in the United States. Our aim was to explore real-world, geographic variations in the use of biologic classes and outcomes within the Corrona Psoriasis Registry. Patient demographics and disease characteristics were assessed at biologic initiation and at 6 months. Logistic regressions were conducted to evaluate the odds of achieving targeted outcomes for seven United States geographic regions. We examined 737 biologic initiations among 717 patients. IL-17 inhibitors were used most frequently (45%), followed by IL-12âIL-23 and IL-23 inhibitors (38%) and TNF inhibitors (17%). The proportions of patients with obesity (body mass index > 30) and very severe psoriasis (body surface area > 20) were greatest in the East South Central and West South Central regions. After adjusting for age, sex, race, body mass index, and baseline body surface area, decreased odds of achieving 75% improvement in PASI at 6 months were observed among patients in the East South Central (OR = 0.47, 95% confidence interval = 0.28-0.79, P = 0.004), West South Central (OR = 0.43, 95% confidence interval = 0.22-0.87, P = 0.019), and Pacific (OR = 0.49, 95% confidence interval = 0.28-0.84, P = 0.010) regions compared with those observed among patients in the Northeast. The East South Central and West South Central regions may have the greatest frequencies of very severe disease burden and, along with the Pacific region, may be less likely to achieve targeted response within 6 months of initiating biologic therapy.
RESUMEN
BACKGROUND: Biopharmaceuticals revolutionised inflammatory bowel disease (IBD) treatment. However, it is postulated they compromise immunity, collagen production and angiogenesis resulting in infective post-operative complications and altered wound/anastomotic healing. Research has failed to agree on risks associated with perioperative biologics therefore it was anticipated that a systematic review may provide a consensus and contribute recommendations for clinical practice. METHODS: A systematic review conducted as per PRISMA guidelines included a methodical search of PubMed, Google Scholar, EMBASE/Ovid and Cochrane Library using MeSH and/or keywords for papers published between 01/01/1998 and 04/02/2019.The population analysed included adult ulcerative colitis, Crohn's disease, Indeterminate Colitis or IBD unclassified patients. The intervention was intra-abdominal surgery in patients treated with biological therapy in the preceding 12 weeks compared to patients who had intra-abdominal surgery without biological therapy within the defined timeframe. The primary outcome was surgical site infection (SSI) with secondary outcomes including wound dehiscence, intra-abdominal sepsis/abscess, systemic infection and anastomotic breakdown within 30 days post-procedure. Papers were evaluated by two independent reviewers and those included were assessed for quality/bias using the Newcastle-Ottowa scale. RESULTS: 2064 UC, Crohn's and IC patients were analysed across 8 included studies. Several studies' multivariate analyses demonstrated corticosteroids to be independent predictors of morbidity. There are no increased complications associated with anti-TNFα exposure while vedolizumab increased SSI and small bowel obstruction. CONCLUSION: Prospective studies and randomised control trials are required to clarify study outcomes and recommendations published to date. Presently, biologics should continue to be used and considered beneficial in this population.

BACKGROUND: Previous studied revealed that psoriasis and Inflammatory bowel disease (IBD) have highly overlapping epidemiological characteristics, genetic susceptibility loci, disease risk factors, immune mechanisms, and comorbidities. More and more biologics have been used to treat psoriasis and IBD. Interleukin (IL)-17 inhibitors played an important role in the treatment of psoriasis, but induced and aggravated inflammatory bowel disease in some patients. IL-23 inhibitors have shown to be effective to both psoriasis and CD. CASE PRESENTATION: Forty-one year old Chinese male patient who came to the hospital for psoriasis, developed severe gastrointestinal symptoms after using an IL-17 inhibitor, and was diagnosed with Crohn's disease (CD). The patient eventually used an IL-23 inhibitor to relieve both psoriasis and CD. CONCLUSION: IBD patients and psoriasis patients have increased probability of suffering from the other disease. The case that patients had suffered from psoriasis and CD before the use of IL-17 inhibitor is quite rare. This case suggests that physicians need to be careful when treating patients with psoriasis and CD with biologics, and it is necessary to evaluate the gastrointestinal tract.
