Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of morbidity and mortality despite effective low-density lipoprotein cholesterol-targeted therapies. This review explores the crucial role of inflammation in the residual risk of ASCVD, emphasizing its impact on atherosclerosis progression and plaque stability. Evidence suggests that high-sensitivity C-reactive protein (hsCRP), and potentially other inflammatory biomarkers, can be used to identify the inflammatory residual ASCVD risk phenotype and may serve as future targets for the development of more efficacious therapeutic approaches. We review the biological basis for the association of inflammation with ASCVD, propose new therapeutic strategies for the use of inflammation-targeted treatments, and discuss current challenges in the implementation of this new treatment paradigm for ASCVD.

Yao syndrome, a rare autoinflammatory disorder linked to mutations in the nucleotide-binding oligomerization domain-containing protein-2 (NOD2) gene, manifests through periodic fever, polyarthritis, dermatitis, gastrointestinal disturbances, and sicca-like symptoms. The therapeutic landscape is limited, primarily encompassing glucocorticoids, interleukin-1 (IL-1), and IL-6 inhibitors. This report details the case of a teenager with periodic fevers, arthritis, livedo reticularis, and NOD2 gene mutations R702W and IVS8+158C consistent with Yao syndrome. The individual demonstrated significant improvement with canakinumab therapy. This case report aims to enhance recognition and understanding of Yao syndrome\'s clinical spectrum and management options.

OBJECTIVE: Still\'s disease is a rare autoinflammatory disorder characterized by systemic inflammation, fever, rash, and arthritis. The term \"Still\'s disease\" covers the pediatric subtype systemic Juvenile Idiopathic Arthritis (sJIA) and adult-onset Still\'s disease (AOSD), which affects adults. Biological drugs, including anti-interleukin-1 agents anakinra, canakinumab, rilonacept, and the interleukin-6 antagonist tocilizumab, are used in the management of Still\'s disease.
METHODS: We conducted a systematic review and network meta-analysis of randomized controlled trials, and the study protocol was registered in PROSPERO (CRD42023450442). MEDLINE, EMBASE, and CENTRAL were screened from inception until September 17, 2023. We included patients with Still\'s disease who received placebo or biological drugs: anakinra, canakinumab, rilonacept, or tocilizumab. The primary efficacy and safety outcomes were achievement of ACR50 response and occurrence of serious adverse events, respectively. The interventions were ranked using rankograms and SUCRA values.
RESULTS: Nine trials with 430 patients were included. All biological drugs were associated with greater odds of ACR50 response compared with placebo. There was no statistically significant association between biological drugs and serious adverse events. The multivariate meta-analysis found no difference between biological drugs. As per SUCRA rankings, anakinra was the most effective and safe option with respect to ACR50 response and occurrence of serious adverse events.
CONCLUSIONS: This is the first systematic review and meta-analysis to assess the efficacy and safety of biological drugs in pediatric and adult patients with Still\'s disease. Biological drugs were effective in achieving ACR response and demonstrated a low adverse event profile in the management of Still\'s disease.

The role of inflammation in the pathophysiology of acute myocardial infarction (AMI) is well established. In recognizing inflammation\'s pivotal role in AMI, this manuscript systematically traces the historical studies spanning from early attempts to the present landscape. Several anti-inflammatory trials targeting inflammation in post-AMI have been performed, and this review includes the key trials, as well as examines their designs, patient demographics, and primary outcomes. Efficacies and challenges are analyzed, thereby shedding light on the translational implications of trial outcomes. This article also discusses emerging trends, ongoing research, and potential future directions in the field. Practical applications and implications for clinical practice are considered by providing a holistic view of the evolving landscape of anti-inflammatory interventions in the context of AMI.

This scoping review explores the effectiveness of IL-1 pathway inhibitors in managing PSTPIP1-associated inflammatory diseases (PAID). These diseases are marked by abnormal IL-1 pathway activation due to genetic mutations.
Our methodology adhered to a pre-published protocol and involved a thorough search of MEDLINE and EMBASE databases up to February 2022, following the Joanna Briggs Institute Reviewer\'s Manual and the PRISMA Extension for Scoping Reviews. The review included studies reporting on IL-1 pathway inhibitor use in PAID patients.
From an initial pool of 5,225 articles, 36 studies involving 43 patients were selected. The studies predominantly used observational designs and exhibited diversity in patient demographics, treatment approaches, and outcomes. Anakinra and canakinumab demonstrated promise in treating sterile pyogenic arthritis, pyoderma gangrenosum, and acne (PAPA) and PSTPIP1-associated myeloid-related-proteinemia inflammatory (PAMI) syndromes, with scant data on other syndromes. Notably, there was a paucity of information on the adverse effects of these treatments, necessitating cautious interpretation of their safety profile.
Current evidence on IL-1 pathway inhibitors for PAID is primarily from observational studies and remains limited. Rigorous research with larger patient cohorts is imperative for more definitive conclusions. Collaborative efforts among specialized research centers and international health initiatives are key to advancing this field.

OBJECTIVE: FMF is the most common hereditary monogenic fever syndrome marked by recurrent attacks of fever and polyserositis. Colchicine is the current recommended first-line treatment for FMF. However, a small portion of FMF patients are unresponsive or intolerant to colchicine. Anti-IL-1 agents are alternative treatment options for colchicine-resistant or -intolerant FMF patients. This systematic review and meta-analysis aimed to provide qualitative and quantitative evidence for the efficacy and safety of anti-IL-1 agents in adult and paediatric FMF patients.
METHODS: MEDLINE, EMBASE, CENTRAL and Web of Science were screened from inception to May 2023. We included adult and paediatric FMF patients who received continuous treatment with at least one of the anti-IL-1 drugs: anakinra, canakinumab and rilonacept. The primary efficacy outcome was the proportion of patients who achieved complete remission of attacks and the primary safety outcome was the proportion of patients who experienced at least one adverse event during treatment. A random-effects meta-analysis was performed for the quantitative synthesis.
RESULTS: Fourty-four reports consisting of 1399 FMF patients were included. Sixty percent (95% CI 49%, 72%) of the adult patients and 81% (95% CI 72%, 89%) of the paediatric patients achieved complete remission. Anti-IL-1 agents significantly decreased levels of inflammatory markers. At least one adverse event was observed in 25% (95% CI 13%, 37%) of the adult patients and 12% (95% CI 3%, 21%) of the paediatric patients.
CONCLUSIONS: Anti-IL-1 agents were effective and demonstrated a low adverse event profile in paediatric and adult FMF patients.

The objective of this systematic review was to assess the effects of interleukin-1β (IL-1β) inhibitors on gout flares.
Studies published between 2011 and 2022 that evaluated the effects of IL-1β inhibitors in adult patients experiencing gout flares were eligible for inclusion. Outcomes including pain, frequency and intensity of gout flares, inflammation, and safety were assessed. Five electronic databases (Pubmed/Medline, Embase, Biosis/Ovid, Web of Science and Cochrane Library) were searched. Two independent reviewers performed study screening, data extraction and risk of bias assessments (Cochrane Risk of Bias Tool 2 for randomised controlled trials [RCTs] and Downs and Black for non-RCTs). Data are reported as a narrative synthesis.
Fourteen studies (10 RCTs) met the inclusion criteria, with canakinumab, anakinra, and rilonacept being the three included IL-1β inhibitors. A total of 4367 patients with a history of gout were included from the 14 studies (N = 3446, RCTs; N = 159, retrospective studies [with a history of gout]; N = 762, post hoc analysis [with a history of gout]). In the RCTs, canakinumab and rilonacept were reported to have a better response compared to an active comparator for resolving pain, while anakinra appeared to be not inferior to an active comparator for resolving pain. Furthermore, canakinumab and rilonacept reduced the frequency of gout flares compared to the comparators. All three medications were mostly well-tolerated compared to their comparators.
IL-1β inhibitors may be a beneficial and safe medication for patients experiencing gout flares for whom current standard therapies are unsuitable.

Myocarditis has been reported as a life-threatening complication of adult-onset Still\'s disease (AOSD), but fulminant myocarditis with AOSD is very rare. We hereby report a case of a 43-year-old female with fulminant myocarditis with AOSD. She had a refractory AOSD and cardiogenic shock with markedly elevated ferritin level up to 67,370 ng/mL. She was successfully treated with canakinumab and mechanical circulatory support (MCS) such as venoarterial extracorporeal membrane oxygenation and Impella CP. We also reviewed the previous cases of fulminant myocarditis with AOSD published from 1976 to December 2022, and only 8 cases of fulminant myocarditis with AOSD have been reported. The characteristics of these cases showed that the average age at presentation was 37.6 years (range 24-47 years). The time to myocarditis from the onset of AOSD ranged from 2 weeks to 2 years; however, most cases developed myocarditis within 1 year. Initial presenting symptoms included fever, dyspnea, chest pain, myalgia, rash, and sore throat. The median peak ferritin was 13,000 ng/mL. Left ventricular ejection fractions were not greater than 35%. Our case was the first reported case successfully treated with canakinumab and MCS. This review suggests that myocarditis may be an early phase of the complication in patients with AOSD, and the severity of AOSD may correlate with the severity of myocarditis. Canakinumab for AOSD and MCS for fulminant myocarditis may be one of the choices for overcoming the comorbidities.

This study evaluated the clinical efficacy and safety of interleukin-1 (IL-1) blockade for patients with COVID-19.
The PubMed, Web of Science, Ovid Medline, Embase and Cochrane Library databases were searched for relevant articles from their inception to 25 September 2022. Only randomized clinical trials (RCTs) that assessed the clinical efficacy and safety of IL-1 blockade in the treatment of patients with COVID-19 were included.
This meta-analysis included seven RCTs. No significant difference in the all-cause mortality rate of patients with COVID-19 was observed between the IL-1 blockade and control groups (7.7 vs. 10.5%, odds ratio [OR] = 0.83, 95% confidence interval [CI] 0.57-1.22; I2 = 18%). However, the study group was at significantly lower risk of requiring mechanical ventilation (MV) compared with the control group (OR = 0.53, 95% CI 0.32-0.86; I2 = 24%). Finally, the risk of adverse events was similar between the two groups.
IL-1 blockade does not provide increased survival benefits in hospitalized patients with COVID-19, but it may reduce the need for MV. Furthermore, it is a safe agent for use in the treatment of COVID-19.>.
