Brehm TT, Reimann M, Köhler N, Lange C. (Re-)introduction of TNF antagonists and JAK inhibitors in patients with previous tuberculosis: a systematic review. Clin Microbiol Infect 2024; 30:989-998. [PMID: 38663653 DOI: 10.1016/j.cmi.2024.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 04/14/2024] [Accepted: 04/17/2024] [Indexed: 05/20/2024]
Abstract
BACKGROUND Tuberculosis (TB) is a common complication associated with treatment with tumour necrosis factor (TNF) antagonists and Janus kinase (JAK) inhibitors. However, there is uncertainty about the risk of TB relapse in patients with TB and comorbidities requiring treatment with these agents. OBJECTIVES To assess the risk of TB relapse in patients (re-)started on TNF antagonists or JAK inhibitors. METHODS Systematic review. DATA SOURCES PubMed and Cochrane Library databases until 11 December 2023. STUDY ELIGIBILITY CRITERIA Randomized control trials, prospective and retrospective cohort studies, case reports and case series. PARTICIPANTS Patients with current or previous TB who were (re-)started on TNF antagonists or JAK inhibitors. INTERVENTIONS (Re-)introduction of TNF antagonists and JAK inhibitors. ASSESSMENT OF RISK OF BIAS All studies meeting entry criteria were included regardless of quality. METHODS OF DATA SYNTHESIS Categorical data are presented as frequencies and percentages. For non-normally distributed aggregated data, we calculated the pooled weighted median with 95% CI. For individual patient data, the median and interquartile range (IQR) were calculated. RESULTS Of 5018 articles screened for eligibility, 67 publications reporting on 368 TB patients who (re-)initiated treatment with TNF antagonists for underlying diseases were included. The median age was 42.5 years (95% CI: 40.4-42.5) and the proportion of female patients was 36.6% (n = 74) of patients whose sex was reported. A total of 14 patients (3.8%, 95% CI: 2.1-6.3%) developed TB relapse after a median of 8.5 months (interquartile range, 6.8-14.8 months) following (re-)initiation of anti-TNF treatment. Furthermore, among 251 articles screened for eligibility, 11 reports on TB patients who were (re-)started on JAK inhibitors for underlying diseases were identified. The median age was 62 years (interquartile range, 48.5-68.5 years) and 45.5% (n = 5) were female. Only one patient (9.1%; 95% CI: 0.2-41.3%) had TB reactivation 10 months after starting treatment with ruxolitinib. In addition, 94 patients who were treated with TNF antagonists and two patients temporarily treated with JAK inhibitors for the prevention or treatment of paradoxical reactions were analysed. None of the publications reported microbiological failure or worsening of TB-related symptoms. CONCLUSIONS (Re-)initiation of TNF antagonists and JAK inhibitors may be relatively safe in patients with current or previous TB and the need for further treatment of underlying diseases.

Abstract
BACKGROUND Psoriasis is a chronic, systemic inflammatory disease with a worldwide prevalence of approximately 2%. Currently, despite the difficulties faced every day by patients and physicians in low-resource countries, literature describing the exact needs of psoriasis treatment in Latin America remains scarce. OBJECTIVE To investigate the unmet needs in psoriasis treatment in Latin America. METHODS The authors conducted a systematic review following PRISMA statements in PubMed, Embase, and LILACS of studies published from January 2011 to March 2021 addressing challenges in psoriasis treatment in Latin America. RESULTS The search strategy identified 3,837 articles, of which 19 were included in the final analysis. Most were from Brazil (58%; n=11), all were observational, and most were cross-sectional (84%; n=16). Difficulties faced by psoriasis patients in Latin America included the high prevalence of opportunistic and endemic infections (42% of the studies addressed this matter; n=8), delay in diagnosis (5%; n=1), work productivity impairment (16%; n=3), limited access to medication/medical care (37%; n=7), poor adherence to treatment (5%; n=1) and poor adherence to guidelines (11%; n=2). STUDY LIMITATIONS Number and quality of studies currently available on this subject. CONCLUSIONS Current psoriasis guidelines do not always account for epidemiological, financial, and cultural characteristics. Most studies available are from Brazil, which might not accurately represent Latin America as a whole. In a region where neglected diseases and scarce resources remain a reality, it is imperative that dermatological training be offered to primary care providers, allowing for standardized conduct and earlier diagnosis.

Abstract
Psoriasis is a common cutaneous disease, and often these patients require treatment with biologics. Screening for latent tuberculosis is an important step in the pre-biologic work-up. A 58-year-old woman with moderate-to-severe psoriasis was found to be positive for latent tuberculosis during pre-biologic screening. She received rifampicin for 6 months and had complete resolution of her psoriasis, with persistent remission at 1-year follow-up. Improvement could be attributed to the immunomodulatory effects of rifampicin. Another theory proposes the existence of a tuberculosis-related type of psoriasis that improves when tuberculosis is adequately treated.

Abstract
The tuberculosis (TB) burden is high in China, with a 32% prevalence of latent tuberculosis infection (LTBI) in Beijing. Screening for LTBI and the chemoprophylaxis of positive patients are recommended prior to biologic therapy. To evaluate the TB-related safety of secukinumab (SEC) in a cohort of plaque psoriasis patients with LTBI receiving different treatments. Plaque psoriasis patients eligible for SEC treatment were screened for TB. LTBI patients (QuantiFeron-TB test positive, QFT+) receiving SEC were closely monitored by chest radiograph, ESR or hs-CRP, and blood counts every 12 to 20 weeks for active TB infection. QFT_patients receiving SEC treatment were screened for LTBI every 6 to 12 months. Of 42 patients treated with SEC, 19 were QFT+ (45.24%). A QFT_patient became QFT+ after 6 months treatment. Two patients started SEC treatment from 2015 to 2016 and were followed up 268 and 216 weeks later, respectively. Three patients received chemoprophylaxis, 17 did not because of safety concerns or being unable to complete the process. During the 16- to 268-week follow-up, no signs of TB reactivation were observed in the 20 LTBI patients receiving SEC. Plaque psoriasis patients with LTBI who received no chemoprophylaxis could be safely treated with SEC.

Abstract
BACKGROUND Tuberculosis (TB) screening is mandatory for psoriasis biologic treatment. However, evidences regarding TB screening results during biologic treatment are conflicting. OBJECTIVES The aim of this study is to evaluate the rate of QuantiFERON TB Gold test (QFT) conversion in psoriasis patients during biologics over time. METHODS A 9-year single center retrospective study was performed in order to evaluate the rate of QFT conversion in patients affected by moderate-to-severe plaque psoriasis under available biological therapies (anti-TNF-α, IL-12/23, IL-17). For each patient, demographic data, age, gender, comorbidities, previous psoriasis therapy, as well as ongoing treatment type were registered. Five-hundred twenty-six patients (61.2% male, with a mean age of 52.6 ± 13.9 years) treated with biologics were enrolled. RESULTS QFT conversion occurred in 6.5% of patients over a mean treatment duration of 3.2 years. On average, QFT conversion occurred after 34.05 months of treatment. Anti-TNF-α drugs, and among them, adalimumab above all (35.5% of all cases), were the most commonly involved treatment during QFT conversion, followed by anti-IL-12/23 (17.6%) and anti-IL-17 (14.7%). However, differences among biologics class or single biologics (adalimumab, etanercept, infliximab, golimumab, certolizumab, ustekinumab, ixekizumab, secukinumab) did not approach statistical significance. CONCLUSIONS Annual TB screening is important in psoriasis patients under biologic treatment in order to avoid possible latent TB infection reactivation. Indeed, our data showed that even in a low TB prevalence country like Italy, QFT may convert over time in psoriasis patients under biologics in 6.5% of the cases.

Abstract
Psoriasis (PsO) is a common, systemic, chronic, inflammatory disease characterized by key clinical symptoms, including itching, pain, and scaling. PsO is associated with a high prevalence of comorbidities, including other autoimmune diseases and malignancies. Furthermore, special populations, such as pregnant, pediatric, and elderly patients, and those with erythrodermic PsO, are challenging to treat and require tightly monitored disease and treatment management. Because certain populations have demographic or clinical characteristics that can affect the presentation of PsO and complicate treatment responses, these patient populations are largely excluded from clinical trials; therefore, most clinical evidence for the treatment of these patients is derived from case reports and series. Secukinumab, a fully human monoclonal interleukin-17A antibody, has been shown in several clinical trials to be effective and safe for the treatment of PsO; however, these studies offer only limited data on the use of secukinumab in patients with chronic illnesses or in special populations. This review explores the use of secukinumab for PsO in special populations, including pregnant women, children, elderly people, patients with erythrodermic PsO, and those with chronic illnesses, including latent tuberculosis, hepatitis B and C, HIV, multiple sclerosis, and malignancies.

Abstract
Immunosuppressive therapies, effective in treating inflammatory disorders such as psoriasis, increase the risk of serious infections, such as tuberculosis (TB). For example, tumour necrosis factor (TNF)-alpha inhibitors significantly increase the risk of TB reactivation in patients with latent TB infection (LTBI), which has led clinicians to routinely test for TB prior to initiation of these medications. This protocol has since extended to other, newer immunomodulatory therapies for psoriasis, such as interleukin (IL)-17 inhibitors, including secukinumab, ixekizumab and brodalumab. We conducted a systematic review to examine whether there is any evidence that IL-17 inhibitor therapy for psoriasis increases the risk of TB reactivation. Using PubMed and EMBASE, our literature search resulted in 139 total articles. After manually reviewing each article for the discussion of IL-17 inhibitors for psoriasis, with data originating from clinical trials, and assessment for incidence of TB reactivation, 23 articles met the full inclusion criteria for our review. Overall, we found no cases of TB reactivation in patients treated with IL-17 inhibitors for psoriasis. This suggests that IL-17 inhibitors may be safely used in psoriasis patients with LTBI who receive appropriate LTBI treatment. However, long-term real-world studies are warranted to further evaluate this risk.

Abstract
Background Many international guidelines have been introduced with the aim of helping clinicians by providing evidence-based advice for the prescription of biologic therapies in psoriasis. Because no local or regional guideline is available, the treatment of psoriasis with biologics is mainly based on clinical experiences regarding the international guideline among Iranian dermatologists. Objective To assess the knowledge and attitudes among Iranian specialists regarding the use of biologic agents to manage psoriasis. Methods Data were collected using an electronic questionnaire specifically designed for this study based on a review of the literature. The designed Google form consisted of 53 multiple choice questions divided into five sections. Results A total of 111 dermatologists agreed to participate in this study. There was considerable variation among the responding dermatologists in terms of their knowledge and attitudes toward biologics. There were some significant associations between knowledge and attitudes of dermatologists toward biologics and their personal and professional characteristics. Conclusions More comprehensive educational approaches, both in the dermatology residency and postgraduation periods, could be very beneficial to promote the knowledge and attitude of the dermatologist in treating psoriasis with biologic agents. This study could be one of the first steps to develop a country-based or a region-based plan to improve the knowledge and attitude among dermatologists regarding the use of biologic drugs in psoriasis and possibly to reach a better status to prescribe these agents in the management of psoriasis.

Abstract
BACKGROUND Biologic therapies pose a risk for opportunistic infections, especially for reactivating latent tuberculosis infection (LTBI). OBJECTIVE The aim was to describe the clinical features and mortality rate of active Mycobacterium tuberculosis (TB) in psoriasis patients receiving biologic therapies. METHODS A systematic review of PubMed, Google Scholar, ScienceDirect, Cochrane Library, and ClinicalTrials.gov databases was performed. Studies describing active TB in patients with psoriasis receiving biologic therapy from inception to May 31, 2018 were included. Clinical data as well as mortality rates were recorded. RESULTS Fifty-one studies were included, evaluating 78 patients with active TB: 11 prospective studies, 13 retrospective, and 27 case reports/series. Most patients (73%) with active TB were male, the mean age was 48 ± 13 years, and 85% were of European or Asian origin. Pre-treatment LTBI screening was negative for 63% of patients. Disease presented in 33% of patients within the first 3 months of treatment, and in 51% within the first 6 months. Most patients (72%) presented with extra-pulmonary TB, and 49% had disseminated disease. The mortality rate was 7%. LIMITATIONS Limitations of this review are its small sample size and inclusion of case reports. CONCLUSIONS Some patients develop active TB despite LTBI screening. Clinicians initiating biologic therapy in patients with psoriasis should be aware of the clinical features of active TB in this scenario.

Abstract
Psoriasis, which is a common chronic inflammatory skin disease, endangers human health and brings about a major economic burden worldwide. To date, treatments for psoriasis remain unsatisfied because of their clinical limitations and various side effects. Thus, developing a safer and more effective therapy for psoriasis is compelling. Previous studies have explicitly shown that psoriasis is an autoimmune disease that is predominantly mediated by T helper 17 (Th17) cells, which express high levels of interleukin-17 (IL-17) in response to interleukin-23 (IL-23). The discovery of the IL-23–Th17–IL-17 axis in the development of psoriasis has led to the paradigm shift of understanding pathogenesis of psoriasis. Although anti-IL-17 antibodies show marked clinical efficacy in treating psoriasis, compared with antibodies targeting IL-17A or IL-17R alone, targeting Th17 cells themselves may have a maximal benefit by affecting multiple proinflammatory cytokines, including IL-17A, IL-17F, IL-22, and granulocyte-macrophage colony-stimulating factor, which likely act synergistically to drive skin inflammation in psoriasis. In this review, we mainly focus on the critical role of Th17 cells in the pathogenesis of psoriasis. Especially, we explore the small molecules that target retinoid-related orphan receptor γt (RORγt), a vital transcription factor for Th17 cells. Given that RORγt is the lineage-defining transcription factor for Th17 cell differentiation, targeting RORγt via small molecular inverse agonists may be a promising strategy for the treatment of Th17-mediated psoriasis.
