Prevalence and predictors of sustained remission/low disease activity after discontinuation of induction or maintenance treatment with tumor necrosis factor inhibitors in rheumatoid arthritis: a systematic and scoping review.
BACKGROUND
To determine the prevalence of sustained remission/low disease activity (LDA) in patients with rheumatoid arthritis (RA) after discontinuation of tumor necrosis factor inhibitors (TNFi), separately in induction treatment and maintenance treatment studies, and to identify predictors of successful discontinuation.
METHODS
We performed a systematic literature review of studies published from 2005 to May 2022 that reported outcomes after TNFi discontinuation among patients in remission/LDA. We computed prevalences of successful discontinuation by induction or maintenance treatment, remission criterion, and follow-up time. We performed a scoping review of predictors of successful discontinuation.
RESULTS
Twenty-two induction-withdrawal studies were identified. In pooled analyses, 58% (95% confidence interval (CI) 45, 70) had DAS28 < 3.2 (9 studies), 52% (95% CI 35, 69) had DAS28 < 2.6 (9 studies), and 40% (95% CI 18, 64) had SDAI ≤ 3.3 (4 studies) at 37-52 weeks after discontinuation. Among patients who continued TNFi, 62 to 85% maintained remission. Twenty-two studies of maintenance treatment discontinuation were also identified. At 37-52 weeks after TNFi discontinuation, 48% (95% CI 38, 59) had DAS28 < 3.2 (10 studies), and 47% (95% CI 33, 62) had DAS28 < 2.6 (6 studies). Heterogeneity among studies was high. Data on predictors in induction-withdrawal studies were limited. In both treatment scenarios, longer duration of RA was most consistently associated with less successful discontinuation.
CONCLUSIONS
Approximately one-half of patients with RA remain in remission/LDA for up to 1 year after TNFi discontinuation, with slightly higher proportions in induction-withdrawal settings than with maintenance treatment discontinuation.

Meta-Analysis
AIMS
The aim of this study was to systematically review and analyze differences in the levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) comparing metabolically healthy but obese (MHO) with metabolically healthy non-obese (MHNO), metabolically unhealthy non-obese (MUNO), and metabolically unhealthy obese (MUO) subjects.
DATA SYNTHESIS
We searched PubMed, Embase, Web of Science, and Scopus for studies that matched the relevant search terms. Differences in inflammatory marker levels between MHO and the other three phenotypes were pooled as standardized mean differences (SMD) or differences of medians (DM) using a random-effects model. We included 91 studies reporting data on 435,007 individuals. The CRP levels were higher in MHO than in MHNO subjects (SMD = 0.63, 95% CI: 0.49, 0.76; DM = 0.83 mg/L, 95% CI: 0.56, 1.11). The CRP levels were higher in MHO than in MUNO subjects (SMD = 0.16, 95% CI: 0.05, 0.28; DM = 0.39 mg/L, 95% CI: 0.09, 0.69). The CRP levels were lower in MHO than in MUO individuals (SMD = -0.43, 95% CI: -0.54, -0.31; DM = -0.82 mg/L, 95% CI: -1.16, -0.48). The IL-6 levels in MHO were higher than in MHNO while lower than in MUO subjects. The TNF-α levels in MHO were higher than in MHNO individuals.
CONCLUSIONS
This review provides evidence that CRP levels in MHO are higher than in MHNO and MUNO subjects but lower than in MUO individuals. Additionally, IL-6 levels in MHO are higher than in MHNO but lower than in MUO subjects, and TNF-α levels in MHO are higher than in MHNO individuals.

Review
The aim of this study was to carry out a systematic literature review to investigate the main immune cells responsible for implantation failures. We selected papers from PubMed, Embase and Virtual Health Library databases. Eligible articles included publications between January 1, 2010 and April 24, 2022. Inclusion criteria were: observational and case-control studies; and the exclusion criteria were: review papers, letters to the editor, abstracts, animal studies and case reports. We extracted the following information: day of collection, number of patients, control group, age of patients, type of sample used, immune cells and cytokines. As main findings in our mapping, we found that in peripheral blood, CD3+, CD4+, CD8+, CD16+, CD56+, CD57+, CD69+, CD154+, CD158a+, NKp46 cells were increased and the CD4+, CD45+, Foxp3 and NKp46 markers were reduced. From the endometrial biopsies, there was an increase in CD3+, CD4+, CD5+, CD8+, CD16+, CD25+, CD45+, CD56+, CD57+, CD68+, CD127+ and a reduction in CD45+, CD56+, NKp46 and FoxP3 cells. Cytokines found increased in peripheral blood included IL-6, IL-10, IL-17, INF-γ, TGF-ß, TNF-α; while IL-4, IL-6, IL-10, IL-35, FoxP3, TGF-ß, SOCS3 were reduced. As for the biopsies, there was an increase in IL-2, IL-6, IL-17, IL-22, IL-23, INF-A1, INF-B1, INF-γ, TNF-R and a reduction in IL-6, IL-10, INF-γ, TGFß, TNF-α. We concluded that immune cells can be modulated during pregnancy failure, but further studies are needed to elucidate the modulating effect of the immune system on the endometrium of these patients.

Anti-tumor Necrosis Factor Alpha Versus Corticosteroids: A 3-fold Difference in the Occurrence of Venous Thromboembolism in Inflammatory Bowel Disease-A Systematic Review and Meta-analysis.
BACKGROUND AND AIMS
Patients with inflammatory bowel disease [IBD] have a more than two fold higher risk of venous thromboembolic events [VTE] than the general population. The aetiology is complex, and the role of medication is not precisely defined. We aimed to assess the effects of anti-tumor necrosis factor alpha [anti-TNFα] drugs and conventional anti-inflammatory therapy, namely corticosteroids [CS], immunomodulators [IM], and 5-aminosalicylates [5-ASA] on VTE in IBD.
METHODS
A systematic search was performed in five databases on November 22, 2022. We included studies reporting VTE in the distinct categories of medications, determined the proportions, and calculated the odds ratios [OR] with 95% confidence intervals [CI], using the random-effects model. The risk of bias was evaluated with the Joanna Briggs Institute Critical Appraisal Checklist and the Risk of Bias in Non-randomized Studies of Interventions tool.
RESULTS
The quantitative analysis included 16 observational studies, with data from 91 322 IBD patients. Patients receiving anti-TNFα medication had significantly less VTE [proportion: 0.05, CI: 0.02-0.10], than patients treated with CS [proportion: 0.16, CI: 0.07-0.32], with OR = 0.42 [CI: 0.25-0.71]. IMs resulted in similar proportions of VTE compared with biologics [0.05, CI: 0.03-0.10], with OR = 0.94 [CI: 0.67-1.33]. The proportion of patients receiving 5-ASA having VTE was 0.09 [CI: 0.04-0.20], with OR = 1.00 [CI: 0.61-1.62].
CONCLUSIONS
Biologics should be preferred over corticosteroids in cases of severe flare-ups and multiple VTE risk factors, as they are associated with reduced odds of these complications. Further studies are needed to validate our data.

Meta-Analysis Review
BACKGROUND
Interleukin-36s (IL-36s) are a category of inflammatory cytokines and an increasing number of studies over the past decade have found that different kinds of IL-36s play different roles in cancers. This systematic review and meta-analysis aimed to evaluate the prognostic value of IL-36s in different cancer types.
METHOD
Two reviewers independently searched in PubMed, Cochrane Library and EMBASE up to December 13, 2022. We extracted the hazard ratio (HR) and the confidence intervals (CIs) of the related prognostic outcomes and analyzed the pooled HR.
RESULTS
We included 12 studies including 1925 patients. In all, six studies including IL-36α, five including IL-36γ and one including IL-36β. A high expression of IL-36α was associated with better overall survival (OS) (HR = 0.48, 95 %CI: 0.37-0.62, P < 0.001) of cancer patients. The expression of IL-36γ was not related with cancers. Further, subgroup analysis showed that the expression of IL-36γ had no correlation with the OS of colorectal cancer (CRC) and non‑small cell lung cancer (NSCLC) patients. Interestingly, a high expression of IL-36γ played contrasting prognostic roles in hepatocellular carcinoma (HCC) (HR = 0.43, 95 %CI: 0.27-0.69, P < 0.001) patients and gastric cancer (GC) (HR = 1.58, 95 %CI: 1.33-1.87, P < 0.001) patients. The only IL-36β related study showed the expression of IL-36β was not correlated with the prognosis of CRC patients (P > 0.05).
CONCLUSION
IL-36α, IL-36β and IL-36γ possibly play different roles in different cancers. High expression of IL-36α may be associated with good prognostic value in cancer patients, especially in CRC patients. The association between cancers prognosis and expression of IL-36β or IL-36γ needs further evaluation. These conclusions need more clinical prognostic data for confirmation.

Meta-Analysis
BACKGROUND
This systematic review and meta-analysis aimed to evaluate the efficacy of engineered extracellular vesicles (EEVs) in the treatment of ischemic stroke (IS) in preclinical studies and to compare them with natural extracellular vesicles (EVs). The systematic review provides an up-to-date overview of the current state of the literature on the use of EEVs for IS and informs future research in this area.
METHODS
We searched PubMed, EMBASE, Web of Science, Cochrane Library, and Scopus databases for peer-reviewed preclinical studies on the therapeutic effect of EEVs on IS.Databases ranged from the inception to August 1, 2023. The outcome measures included infarct volumes, neurological scores, behavioral scores, apoptosis rates, numbers of neurons, and levels of IL-1β, IL-6, and TNF-α. The CAMARADES checklist was used to assess the quality and bias risks of the studies. All statistical analyses were performed using RevMan 5.4 software.
RESULTS
A total of 28 studies involving 1760 animals met the inclusion criteria. The results of the meta-analysis showed that compared to natural EVs, EEVs reduced infarct volume (percentage: SMD = -2.33, 95% CI: -2.92, -1.73; size: SMD = -2.36, 95% CI: -4.09, -0.63), improved neurological scores (mNSS: SMD = -1.78, 95% CI: -2.39, -1.17; Zea Longa: SMD = -2.75, 95% CI: -3.79, -1.71), promoted behavioral recovery (rotarod test: SMD = 2.50, 95% CI: 1.81, 3.18; grid-walking test: SMD = -3.45, 95% CI: -5.15, -1.75; adhesive removal test: SMD = -2.60, 95% CI: -4.27, -0.93; morris water maze test: SMD = -3.91, 95% CI: -7.03, -0.79), and reduced the release of proinflammatory factors (IL-1β: SMD = -2.02, 95% CI: -2.77, -1.27; IL-6: SMD = -3.01, 95% CI: -4.47, -1.55; TNF-α: SMD = -2.72, 95% CI: -4.30, -1.13), increasing the number of neurons (apoptosis rate: SMD = -2.24, 95% CI: -3.32, -1.16; the number of neurons: SMD = 3.70, 95% CI: 2.44, 4.96). The funnel plots for the two main outcome measures were asymmetric, indicating publication bias. The median score on the CAMARADES checklist was 7 points (IQR: 6-9).
CONCLUSIONS
This meta-analysis shows that EEVs are superior to natural EVs for the treatment of IS. However, research in this field is still at an early stage, and more research is needed to fully understand the potential therapeutic mechanism of EEVs and their potential use in the treatment of IS.

BMC Immunology Oct 2023This systematic review aimed to map the evidence evaluated the relationship between vitamin D and redox and inflammatory status during gestation.
OBJECTIVE
This systematic review aimed to map the evidence evaluated the relationship between vitamin D and redox and inflammatory status during gestation.
METHODS
Three databases (PubMed/MEDLINE, Scopus, and Web of Science (WoS)) and reference list of included documents were searched for related observational studies published until 2nd October 2023. To determine the quality of the selected observational studies, the Newcastle-Ottawa Scale (NOS) was used.
RESULTS
After a primary search of three databases, 19492records were appeared. When duplicates and irrelevant documents were removed, 14 articles were found to have eligible criteria. The design of the identified studies was cross-sectional, case-control and cohort. Evidence showed an adverse association between 25(OH)D and the biomarkers of inflammation, such as high-sensitivity C-reactive protein (hs-CRP), Interleukin-1beta (IL-1β), Interleukin-6 (IL-6), and tumor necrosis factor- alfa (TNF-α) during pregnancy. On the contrary, some studies represented that 25(OH)D positively correlated with hs-CRP in the cord blood. One study suggested a direct association between serum concentrations of 25(OH)D and Interleukin-8 (IL-8), macrophage inflammatory protein (MIP), and TNF-α levels in mothers with gestational diabetes mellitus (GDM). A case-control study showed that lower serum concentration of 25(OH)D positively correlated with total antioxidant capacity (TAC) levels in participants.
CONCLUSIONS
Evidence confirmed the supposition of the direct relationship between vitamin D levels and biomarkers with anti-inflammatory and anti-oxidative properties. However, the Existence of inconsistent evidence confirms the need for further studies in mothers with GDM and hypertensive disorders.

CONTEXT
Cardiovascular disease (CVD) is the leading cause of death in the United States. As such, an unmet need exists in the primary and secondary prevention of adverse cardiovascular events (CVEs). Specifically, identifying drugs that can reduce the progression of CVD and serious adverse events is much needed. Drugs that work by reducing platelet aggregation, blocking cholesterol formation (3-hydroxy-3-methyl-glutaryl-coenzyme A [HMG-CoA] reductase inhibitors), and/or blocking inflammation pathways (mainly interleukin-1b [IL-1b]) have been linked to preventing adverse CVEs, including acetylsalicylic acid (ASA, aspirin), statins, colchicine, and IL-1 inhibitors (interleukin-1 receptor antagonists). This systematic review aims to provide insight into utilizing these four agents for the primary and/or secondary prevention of CVD.
OBJECTIVES
In this systematic review, we opted to review the efficacy of aspirin, statins, colchicine, and IL-1 inhibitors in the primary and secondary prevention of CVE to provide clinical practitioners with evidence-based practice approaches and determine any unmet needs in their utilization.
METHODS
Between October 1 and 12, 2021, a search was conducted and completed on five databases: PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, and Biomedical Reference Collection: Comprehensive. A total of 13 researchers (V.A., A.H., S.B., V.G., D.C., C.C., C.B., C.A., S.K., J.H., A.K., S.F., and S.E.) were involved in the search and screening of the articles. Search terms included "aspirin, statins, colchicine, IL-1 inhibitors, and primary, secondary, myocardial infarction (MI)." Inclusion criteria included clinical study design, English language articles, all genders older than 50 years old, and established patient history of CVD, including MI. In addition, articles were excluded if they were animal models, studies, pharmacokinetic studies, systematic reviews, literature reviews, and studies exploring therapies other than those listed in the inclusion criteria. First, five individuals independently sorted through abstracts or articles based on the inclusion and exclusion criteria. Then, a team of 13 individuals sorted through full-text articles of selected abstracts based on the same criteria. A separate researcher resolved conflicts between the team.
RESULTS
A total of 725 articles were identified from all databases, from which 256 duplicated articles were removed. Thus, a total of 469 articles abstracts were screened, of which 425 articles either did not meet the inclusion criteria or met the exclusion criteria. A total of 42 articles were retrieved and assessed for full-text review, from which 15 articles were retrieved for analysis.
CONCLUSIONS
Statins may prevent primary CVEs based on their role in preventing cholesterol formation. Aspirin, canakinumab, and colchicine may be helpful in the secondary prevention of CVEs due to their blocking of various steps in the inflammation pathway leading to CVD. Future research should primarily focus on the use of canakinumab and colchicine in preventing CVD due to the limited number of studies on these drugs.

IMPORTANCE
Postmenopausal women affected by overweight and obesity are susceptible to a variety of diseases due to inflammation. Exercise may reduce the risk of disease by attenuating low-grade chronic inflammation.
OBJECTIVE
We conducted a systematic review and meta-analysis to investigate the effects of exercise on inflammatory markers in postmenopausal women struggling with overweight and obesity.
METHOD
Literature as of May 2023 was searched from databases such as Cochrane, Embase, Pubmed, Web of Science, and EBSCO and English-language randomized controlled trials (RCTs) that meet the inclusion criteria were selected. Studies were included based on the following criteria: (A) Written in English; (B) RCTs; (C) Postmenopausal women impacted by overweight and obesity as research objects; (D) Outcome measurements include CRP, TNF-α, IL-6, and adiponectin; (E) Duration of the exercise intervention is eight weeks.
RESULTS
A total of 34 articles and 2229 participants were included. Exercise can significantly reduce the level of C-reactive protein (CRP) (MD: -0.59, 95 % CI: -0.87 to -0.31, p < 0.00001), tumor necrosis factor-α (TNF-α) (MD: -0.65, 95 % CI: -0.94 to -0.35, p < 0.00001), interleukin-6 (IL-6) (MD: -0.48, 95 % CI: -0.75 to -0.21, p < 0.00001), and exercise can significantly increase the level of adiponectin (MD: 0.33, 95 % CI: 0.02 to 0.65, p = 0.04) in women impacted by overweight and obesity.
CONCLUSION
These results suggest that exercise may be an effective intervention for reducing pro-inflammatory markers and increasing adiponectin in postmenopausal women impacted by overweight and obesity. The findings may provide clinicians and healthcare professionals with insights into the implementation of exercise programs for postmenopausal women living with overweight and obesity.

Meta-Analysis Review
Ustekinumab has recently been approved for the treatment of ulcerative colitis (UC) based on data from clinical trials. However, the effectiveness of ustekinumab in patients with UC in a real-world setting remains unclear. Hence, in this meta-analysis, we aimed to evaluate the effectiveness of ustekinumab in a real-world setting and to investigate the predictors of its effectiveness. A comprehensive literature search was performed to examine the effectiveness of ustekinumab in UC patients admitted between January 2019 and December 2021. Data on clinical remission, response, and corticosteroid-free clinical remission rates were extracted, pooled, and analyzed. Meta-regression analysis was performed to investigate the source of heterogeneity and the impact of moderators on the outcomes of interest. A total of 14 eligible studies were identified. The pooled clinical remission rate was 55.0% at week 8, 36.1% at week 16, 46.6% at month 6, and 38.6% at month 12. The meta-regression analysis showed that prior use of anti-tumor necrosis factor (TNF) agents and vedolizumab and the publication style were significant moderators. Additionally, out of 258 patients, there were 28 adverse events (AEs) (10.9%). The effectiveness of ustekinumab in real-world patients with UC was consistent with the results clinical trials. Moreover, previous treatment with anti-TNF agents and vedolizumab might have affected the effectiveness of ustekinumab.
