(1) Background: The monkeypox virus (MPV) is a double-stranded DNA virus belonging to the Poxviridae family, Chordopoxvirinae subfamily, and Orthopoxvirus genus. It was called monkeypox because it was first discovered in monkeys, in a Danish laboratory, in 1958. However, the actual reservoir for MPV is still unknown. (2) Methods and Results: We have reviewed the existing literature on the options for Monkeypox virus. There are three available vaccines for orthopoxviruses—ACAM2000, JYNNEOS, and LC16—with the first being a replicating vaccine and the latter being non- or minimally replicating. (3) Conclusions: Smallpox vaccinations previously provided coincidental immunity to MPV. ACAM2000 (a live-attenuated replicating vaccine) and JYNNEOS (a live-attenuated, nonreplicating vaccine) are two US FDA-approved vaccines that can prevent monkeypox. However, ACAM2000 may cause serious side effects, including cardiac problems, whereas JYNNEOS is associated with fewer complications. The recent outbreaks across the globe have once again highlighted the need for constant monitoring and the development of novel prophylactic and therapeutic modalities. Based on available data, there is still a need to develop an effective and safe new generation of vaccines specific for monkeypox that are killed or developed into a mRNA vaccine before monkeypox is declared a pandemic.

Olokizumab (OKZ) is a novel IL-6 inhibitor that directly targets IL-6 rather than its receptor. We aim to evaluate the efficacy and safety of OKZ for patients with rheumatoid arthritis (RA) and to investigate the optimal treatment regimen. A systematic review, pairwise, and network meta-analysis synthesizing randomized controlled trials (RCTs) from WOS, CENTRAL, SCOPUS, EMBASE, and PubMed until August 31, 2022. We used the risk ratio (RR) and mean difference (MD) for dichotomous and continuous outcomes, respectively, presented with the corresponding 95% confidence interval (CI). We registered our protocol in PROSPERO with ID: CRD42022358082. Five RCTs with 2277 patients were included. OKZ significantly improved the American College of Rheumatology criteria (ACR) 20 (RR: 1.97 with 95% CI [1.49, 2.58], P = 0.00001), ACR50 (RR: 3.83 with 95% CI [2.13, 6.87], P = 0.00001), ACR70 (RR: 3.83 with 95% CI [2.13, 6.87], P = 0.00001), disease activity score 28 based on C-reactive protein (DAS28-CRP) (RR: 3.91 with 95% CI [2.65, 5.79], P = 0.00001), clinical disease activity index (CDAI) (RR: 2.80 with 95% CI [1.43, 5.48], P = 0.003), and health assessment questionnaire disability index (HAQ-DI) (MD: − 0.28 with 95% CI [− 0.38, − 0.18], P = 0.00001) after 12 weeks, compared to placebo. However, OKZ was also associated with a higher incidence of any adverse events (AEs) (RR: 1.15 with 95% CI [1.06, 1.25], P = 0.0005) and AEs leading to drug discontinuation (RR: 1.86 with 95% CI [1.05, 3.29], P = 0.03). OKZ is effective and with acceptable safety profile when administrated with methotrexate in patients with RA not adequately controlled by tumor necrosis factor inhibitors; however, more large-scale RCTs are still required to investigate the optimal dosing, long-term effects, and comparative efficacy versus established biological DMARDs. Key Points• OKZ is effective especially with methotrexate in RA patients.

Background: The American Society of Haematology defines immune thrombocytopenic purpura (ITP) as a common hematologic disorder characterized by a transient or long-term decrease in platelet counts (< 100 × 109/L.), purpura, and haemorrhagic episodes caused by antiplatelet autoantibodies, with the exclusion of other clinical conditions. We aimed to systematically determine the incidence of ITP in adults and children following influenza vaccination, the duration between vaccination and the occurrence of ITP, and to identify predictors of ITP after the vaccine. Methods: We searched PubMed, Cochrane Library, Google Scholar, Web of Science, Scopus, and Science Direct. We included primary studies that assessed the occurrence of immune thrombocytopenia in individuals who had received any influenza vaccine (primary or booster dose), regardless of the dosage, preparation, time of administration, or age of the participants. We excluded studies that were (a) Narrative, scoping, and umbrella reviews ;(b) studies with no accessible full text, abstract-only studies, or (c) Overlapping or unreliable data. The risk of bias in the included studies was assessed using the Joanna Briggs Institute (JBI) tool. We categorized studies for qualitative analysis based on study design. Descriptive statistics were used to summarize quantitative data, including the incidence of ITP after influenza vaccination. Results: Out of 729 articles retrieved from the database search, we included 24 studies. All patients identified and included in this systematic review presented with immune thrombocytopenia, determined by their platelet count. The period between vaccination and the occurrence of ITP ranged from (2:35 days). The mean duration was 13.5 days. The analysis revealed a statistically significant incidence rate ratio (IRR) = 1.85,95% CI [1.03–3.32] of ITP occurrence after 42 days. Conclusions: Influenza-associated ITP is uncommon, self-limiting, non-life-threatening, and curable. None of the patients reported having severe adverse events or death. Further studies are required to confirm the exact incidence of the ITP to better understand the pathophysiology of ITP development post-influenza vaccination.
