Meta-Analysis
BACKGROUND
The interleukin-1 pathway has been linked to pancreatic diseases. We applied the Mendelian randomization approach to explore whether higher interleukin-1 receptor antagonist (IL-1RA) levels reduce the risk of acute and chronic pancreatitis and pancreatic cancer.
METHODS
Genetic variants associated with blood IL-1RA levels at the genome-wide significance level and located 5MB downstream or upstream of the gene were extracted from a genome-wide meta-analysis of 21,758 participants. After pruning, genetic variants without linkage disequilibrium were used as genetic instrument for IL-1RA. Summary-level data on acute and chronic pancreatitis and pancreatic cancer were obtained from the UK Biobank and FinnGen studies. The associations were meta-analyzed for one outcome from two sources.
RESULTS
Genetically predicted higher levels of IL-1RA were associated with a lower risk of acute and chronic pancreatitis and pancreatic cancer. In the meta-analysis of UK Biobank and FinnGen, the combined odds ratio was 0.87 (95% confidence interval [CI] 0.77-0.97, =0.003) for acute pancreatitis, 0.73 (95% CI 0.65-0.82, =2.93×10) for chronic pancreatitis, and 0.86 (95% CI 0.77-0.96, =0.009) for pancreatic cancer per one standard deviation increment in genetically predicted levels of IL-1RA.
CONCLUSION
This study suggests a protective role of IL-1RA in three major pancreatic diseases, which hints the therapeutic potentials of IL-1RA in pancreatic diseases.

Review
Recent advances have shown impressive results by anti-interleukin 1 (IL-1) agents in refractory idiopathic recurrent pericarditis. PURPOSE OF REVIEW: We critically discuss the current state of the art of therapy of relapsing pericarditis, with a focus on new pharmacological approaches and on specific clinical settings such as pregnancy, pediatric patients, and secondary forms of relapsing pericarditis. RECENT FINDINGS: Antagonism of the IL-1 is highly effective in idiopathic recurrent pericarditis with autoinflammatory features. Currently, available anti-IL-1 agents are anakinra and canakinumab. Rilonacept is another IL-1 antagonist, currently studied in the phase-3 clinical trial RHAPSODY. Available data suggest similar efficacy and safety profiles of these three agents, although only anakinra has been tested in randomized clinical trials. These agents have slightly different pharmacological properties, being canakinumab a specific IL-1ß antagonist while anakinra and rilonacept are unselective IL-1α and IL-1ß blockers. To date, there is no evidence that specificity against IL-1ß affects safety and efficacy in patients with relapsing pericarditis, although it has been proposed that unspecific blockage might be useful in severe disease. Anakinra is the first anti-IL-1 agent with well-documented efficacy and safety in adult and pediatric patients with idiopathic relapsing pericarditis. Other anti-IL-1 agents are currently under study. Future research should clarify the optimal duration of therapy and tapering schedule of treatment with these agents. Moreover, biomarkers would be required to understand which patients will benefit from early administration of IL-1 blockers due to refractoriness to conventional therapy and which others will suffer from recurrences during the tapering of these agents. Lastly, future studies should focus on the subjects with the autoimmune or the pauci-inflammatory phenotype of idiopathic refractory pericarditis.

Review
The Schnitzler syndrome is a rare and underdiagnosed entity which is considered today as being a paradigm of an acquired/late onset auto-inflammatory disease. It associates a chronic urticarial skin rash, corresponding from the clinico-pathological viewpoint to a neutrophilic urticarial dermatosis, a monoclonal IgM component and at least 2 of the following signs: fever, joint and/or bone pain, enlarged lymph nodes, spleen and/or liver, increased ESR, increased neutrophil count, abnormal bone imaging findings. It is a chronic disease with only one known case of spontaneous remission. Except of the severe alteration of quality of life related mainly to the rash, fever and pain, complications include severe inflammatory anemia and AA amyloidosis. About 20% of patients will develop a lymphoproliferative disorder, mainly Waldenström disease and lymphoma, a percentage close to other patients with IgM MGUS. It was exceedingly difficult to treat patients with this syndrome until the IL-1 receptor antagonist anakinra became available. Anakinra allows a complete control of all signs within hours after the first injection, but patients need continuous treatment with daily injections.In many aspects, the Schnitzler syndrome resembles the genetically determined auto-inflammatory syndromes involving activating mutations of the NLRP3 inflammasome. This latter point and its consequences will be addressed.

Meta-Analysis Review
BACKGROUND
At the end of 2021, the European Medicines Agency (EMA) expanded its approval for the recombinant human interleukin-1 (IL-1) receptor antagonist Anakinra for the treatment of COVID-19 patients with elevated soluble urokinase plasminogen activator receptor (suPAR). However, the role of Anakinra in COVID-19 remains unanswered, especially in patients receiving different forms of respiratory support. Therefore, the objective of this systematic review is to assess the safety and effects of Anakinra compared to placebo or standard care alone on clinical outcomes in adult hospitalized patients with SARS-CoV-2 infection.
METHODS
We searched the Cochrane COVID-19 Study Register (comprising MEDLINE, Embase, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, medRxiv, and the Cochrane Central Register of Controlled Trials (CCSR)) and the WHO COVID-19 Global literature on coronavirus disease database to identify completed and ongoing studies from inception of each database to December 13, 2021. Since then, we monitored new published studies weekly up to June 30, 2022 using the CCSR. We included RCTs comparing treatment with Anakinra to placebo or standard care alone in adult hospitalized patients with SARS-CoV-2 infection.
RESULTS
We included five RCTs with 1,627 patients (n = 888, n = 739, mean age 59.63 years, 64% male). Random-effects meta-analysis was used to pool data. We found that Anakinra makes little or no difference to all-cause mortality at up to day 28 compared to placebo or standard care alone (RR 0.96, 95% CI 0.64-1.45; RD 9 fewer per 1000, 95% CI 84 fewer to 104 more; 4 studies, 1593 participants; I = 49%; low certainty of evidence).
CONCLUSIONS
Anakinra has no effect on adult hospitalized patients with SARS-CoV-2 infection regarding mortality, clinical improvement and worsening as well as on safety outcomes compared to placebo or standard care alone.

OBJECTIVES
Anakinra and canakinumab are the most commonly used agents in colchicine resistant/intolerant patients. In this study we investigated long-term efficacy and safety of anakinra and canakinumab.
METHODS
In this retrospective study, we enrolled 101 adult patients with familial Mediterranean fever (FMF). Clinical and laboratory parameters before and after treatment with anakinra/canakinumab and the side effects observed during the treatment were recorded. All patients received anakinra initially and switched to canakinumab, in case of inadequate response/intolerance.
RESULTS
The median (IQR) duration of treatment with anti-IL-1 agents was 35 (24-47.5) months. 101 patients were treated with anakinra and 27 patients with canakinumab. The autoinflammatory diseases activity and attacks decreased with both anakinra and canakinumab. Anakinra was effective in decreasing proteinuria and canakinumab was not effective in decreasing proteinuria in anakinra unresponsive patients. The modified FMF score was achieved in 76.2% of anakinra and 88.9% of canakinumab group. Injection site reactions (ISRs, n:15) was the most common reason of discontinuation of anakinra and most of ISRs developed in first 3 months of treatment. One severe skin rash, two anaphylactic reactions and one severe neutropenia were observed with anakinra; in the first, eighth, twelfth and fiftieth months, respectively. No severe side effects or side effect-related discontinuation of canakinumab were observed.
CONCLUSIONS
Anakinra and canakinumab seem to be effective in long-term management of FMF patients. Canakinumab had a favourable safety/tolerability profile. Anakinra is also generally safe, but the serious side effects that may be observed in the short and long-term use should be taken into account.

Review
Phagocytes fight fungi using canonical and noncanonical, also called LC3-associated phagocytosis (LAP), autophagy pathways. However, the outcomes of autophagy/LAP in shaping host immune responses appear to greatly vary depending on fungal species and cell types. By allowing efficient pathogen clearance and/or degradation of inflammatory mediators, autophagy proteins play a broad role in cellular and immune homeostasis during fungal infections. Indeed, defects in autophagic machinery have been linked with aberrant host defense and inflammatory states. Thus, understanding the molecular mechanisms underlying the relationship between the different forms of autophagy may offer a way to identify drugable molecular signatures discriminating between selective recognition of cargo and host protection. In this regard, IFN- and anakinra are teaching examples of successful antifungal agents that target the autophagy machinery. This article provides an overview of the role of autophagy/LAP in response to fungi and in their infections, regulation, and therapeutic exploitation.

Meta-Analysis Review
As the pandemic progresses, the pathophysiology of coronavirus disease 2019 (COVID-19) is becoming clearer and the potential for immunotherapy is increasing. However, clinical efficacy and safety of immunosuppressants (including tocilizumab, sarilumab and anakinra) treatment in COVID-19 patients are not yet known. We searched PubMed, Embase Medline, Web of Science and MedRxiv using specific search terms in studies published from 1 January 2020 to 20 December 2020. In total, 33 studies, including 3073 cases and 6502 controls, were selected for meta-analysis. We found that immunosuppressant therapy significantly decreased mortality in COVID-19 patients on overall analysis (odds ratio = 0.71, 95% confidence interval = 0.57-0.89, p = 0.004). We also found that tocilizumab and anakinra significantly decreased mortality in patients without any increased risk of secondary infection. In addition, we found similar results in several subgroups. However, we found that tocilizumab therapy significantly increased the risk of fungal co-infections in COVID-19 patients. This represents the only systematic review and meta-analysis to investigate the efficacy and secondary infection risk of immunosuppressant treatment in COVID-19 patients. Overall, immunosuppressants significantly decreased mortality but had no effect on increased risk of secondary infections. Our analysis of tocilizumab therapy showed a significantly increased risk of fungal co-infections in these patients.

Meta-Analysis Review
Heart failure (HF) has become increasingly difficult to manage given its increasing incidence. Despite the availability of novel treatment target relieving inhibition and congestions for neurohormonal activation, heart failure is one of leading health conditions associated with high hospitalization and readmission rates, resulting in poor quality of life. In light of this, this article serves to demonstrate the effect of anakinra as one of the treatment paradigms for HF to explore the need for advanced novel interventions. We conducted a search in five electronic databases, including , , , , and , for RCTs (randomized controlled trials) evaluating the effects of anakinra against placebo in HF. Meta-analysis was performed using RevMan version 5.4. Eight RCTs were obtained and included for analysis in this study. The results demonstrate that anakinra significantly reduces the levels of CRP (C-reactive protein), with significant difference between anakinra- and placebo-treated groups. Analyses also show that CRP failed to cause an improvement in peak oxygen consumption and ventilatory efficiency. Additionally, the treatment-related adverse events were insignificant. Some considerable limitations are that the same set of researchers were involved in most of the studies; hence, more independent studies need to be encouraged. Anakinra was associated with a reduction in CRP levels, indicating some anti-inflammatory effects but no effect on function, exercise capacity, and adverse effects.

BACKGROUND
Studies regarding effectiveness of anakinra and tocilizumab treatments in coronavirus disease 2019 (COVID-19) have contradictory results. Furthermore, there is scarce comparative data regarding superiority of any agent. To further elucidate any superiority between these two agents, we retrospectively investigated and compared outcomes in hospitalized COVID-19 patients of our inpatient cohort who received anakinra or tocilizumab.
METHODS
This study was designed as a single-center, retrospective, cross-sectional cohort study. Hospitalized patients with confirmed diagnosis of COVID-19 who had Brescia-COVID respiratory severity scale score ≥3 and hyperinflammation (defined as elevation of C reactive protein ≥50 g/L or ferritin ≥700 ng/mL) and received anakinra or tocilizumab in addition to standard care were enrolled in the study. Length of hospital stay after initiation of antiinflammatory treatment, need for mechanical ventilation, need for intensive care unit admission, mortality were set as primary outcomes and compared between tocilizumab and anakinra recipients after propensity score matching.
RESULTS
One hundred and six patients were placed in each group after propensity score matching. In the anakinra group, relative risk reduction for intensive care unit admission was 50% when compared to the tocilizumab group and the number needed to treat to avert an intensive care unit admission was 3 (95% CI, 2-5). In terms of mortality, a 52% relative risk reduction was observed with anakinra treatment and the number needed to treat to avert an intensive care unit admission was 8 (95% CI, 4-50). Significantly more patients were observed to receive glucocorticoids in the anakinra group.
DISCUSSION
Anakinra administration in severe COVID-19 patients was significantly associated with better survival and greater clinical improvement compared to the tocilizumab administration in our study. Increased rate of glucocorticoid use in the anakinra group might have contributed to better outcomes.

Observational Study
AIM
Anakinra, an anti IL-1 agent targeting IL-1 alfa and beta, is available for the treatment of recurrent pericarditis in cases with corticosteroid dependence and colchicine resistance after failure of conventional therapies. However, it is unclear if the combination with colchicine, a non-specific inhibitor of the inflammasome targeting the same inflammatory pathway of IL-1, could provide additional benefit to prevent further recurrences. The aim of the present observational study is to assess whether the addition of colchicine on top of anakinra could prolong the time to first recurrence and prevent recurrences better than anakinra alone.
METHODS
International, all-comers, multicentre, retrospective observational cohort study analysing all consecutive patients treated with anakinra for corticosteroid-dependent and colchicine-resistant recurrent pericarditis. The efficacy endpoint was recurrence rate and the time to the first recurrence.
RESULTS
A total of 256 patients (mean age 45.0±15.4 years, 65.6% females, 80.9% with idiopathic/viral aetiology) were included. 64 (25.0%) were treated with anakinra as monotherapy while 192 (75.0%) with both anakinra and colchicine. After a follow-up of 12 months, 56 (21.9%) patients had recurrences. Patients treated with colchicine added to anakinra had a lower incidence of recurrences (respectively, 18.8% vs 31.3%; p=0.036) and a longer event-free survival (p=0.025). In multivariable analysis, colchicine use prevented recurrences (HR 0.52, 95% CI 0.29 to 0.91; p=0.021).
CONCLUSIONS
The addition of colchicine on top of anakinra treatment could be helpful to reduce recurrences and prolong the recurrence-free survival.
