OKG: Writing- original draft, Visualization. Before Controll Clin Trial Clin Ther. Although recent evidence has globally shifted attention towards novel (and much more expensive) ad hoc medications [4], [5], [6], [7], interest in a possible role for cheaper and older compounds remains. The FDA-approved drug ivermectin inhibits the replication of SARS-CoV-2 in vitro. 2021;11:1645. The main reasons for exclusion were infection not recent (56.9%), patient refusal (15.4%), severity score >2 (7.8%) and organisational reasons (7.2%). Ivermectin under scrutiny: a systematic review and meta-analysis of efficacy and possible sources of controversies in COVID-19 patients, https://doi.org/10.1186/s12985-022-01829-8, https://doi.org/10.1186/s12879-021-06348-5, https://doi.org/10.1016/j.jiac.2021.08.021, https://doi.org/10.1016/j.jclinepi.2021.12.018, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/. Publication bias, subgroup, sensitivity, and meta-regression analyses were only done on primary outcomes as a small number of studies have been included in the secondary outcomes. Often, photophobia is accompanied by other symptoms including fatigue, nausea, and head pain. As there are controversies regarding ivermectin, we assessed the quality of studies to minimize the misconceptions. 's retracted study) to investigate the possible role of study quality in pooled results. High-dose ivermectin was safe but did not show efficacy to reduce viral load. A total of 4 RCTs, including 1125 COVID-19 patients, reported an incidence of patients recovered in their studies (Fig. max after the fifth dose should be of the same order as after a single dose of 2 mg/kg, already found to be safe in healthy volunteers [11]. However, the clinical features of the hospitalised participants here were deemed compatible with COVID-19 evolution, and no major neurological signs were observed, as reported previously in cases of serious ivermectin toxicity [23]. In conclusion, we did not demonstrate a significant reduction in viral load between ivermectin and placebo, although a trend for the highest dose is apparent. 2021;27:18534. Disclaimer. Bethesda, MD 20894, Web Policies 1986;1:1558. Population pharmacokinetics of oral ivermectin in venous plasma and dried blood spots in healthy volunteers. The pooled log OR was 0.11 (95% CI 0.220.45) with low heterogeneity (I^2=13.84%, Tau=0.02). Finally, a total of 19 and 17 studies (involving 4328 participants) were included in the systematic review and meta-analysis, respectively. Article Sci Rep. 2016;6:23138. Google Scholar. It analysed 14 randomised trials with ivermectin for COVID-19 published until 26 May 2021 including a total of 1678 participants, finding no evidence favouring ivermectin for clinical outcomes or for viral clearance. .

The exclusion of studies with high or moderate risk of bias from our analyses on primary outcomes resulted in a significant difference in pooled effect results, suggesting that studies with high ROB play a major role in the current confusing state regarding the efficacy of this drug. Studies reporting median and interquartile range for their outcomes were analyzed for no significant skewness [27]. Recruitment was stopped on 10 June 2021 because of a dramatic drop in cases. While your underlying condition is being treated, it may take days or even longer for your photophobia to improve. log10 viral load reduction was 2.9 (1.6) in arm C, 2.5 (2.2) in arm B and 2.0 (2.1) in arm A, with no significant differences (P=0.099 and 0.122 for C vs. A and B vs. A, respectively). For these reasons and for feasibility considerations, it was planned to collect blood samples in a subset of participants at three timepoints: just before and 4 h and 48 h after the fifth dose. The primary efficacy endpoint was the difference in viral load decline from baseline to Day 7. Buonfrate D, Bisoffi Z. Moreover, further information regarding possible therapeutic agents that would reduce mortality and change the course of COVID-19 is desperately needed. Through our manual MEDLINE search, we identified several systematic reviews and meta-analyses based on the results of these fraught studies, reporting an independently significant effect of this drug in their analyses which results in confusion in both clinicians and patients [16,17,18, 61,62,63,64]. An official website of the United States government. There have been several websites providing real time meta-analyses of ivermectin studies (https://ivmmeta.com/#top, https://c19ivermectin.com/) reporting its significant beneficial effect based on non-peer-reviewed low quality trials. While in trials with high ROB, there was a considerable reduction in mortality rate in the ivermectin group (log OR 1.06, 95%CI 1.65 to 0.47; I2=0.00% Tau=0.00) (Fig. Elsevier hereby grants permission to make all its COVID-19-related research that is available on the COVID-19 resource centre - including this research content - immediately available in PubMed Central and other publicly funded repositories, such as the WHO COVID database with rights for unrestricted research re-use and analyses in any form or by any means with acknowledgement of the original source. Our subgroup analysis based on study quality revealed that ivermectin had no significant effect in negative RT-PCR rate in trials with low ROB (log OR -0.14, 95%CI -0.43 to 0.15; I2=0.00%, Tau=0). J Antimicrob Chemother. Although this is an observation, rather than a statistically valid conclusion, it might be questioned whether ivermectin itself could have at least partly contributed to the clinical worsening. in Argentina [31] that used the same dose as our lower-dose arm (600 g/kg). Some of the conditions that trigger photophobia are related to the eye itself and some affect the way the body detects pain. TCR was analysed with Cox regression models and was described by the KaplanMeier method. [19] reported a difference in mean viral load decline of 1.05 log10 copies [standard deviation (S.D.)

Twelve days after parenteral administration of isotonic fluids and IV administration of dexamethasone and dimethyl sulfoxide, the dog returned to a clinically normal neurologic state. Risk of bias was rated as low in 7 trials, some concerns in 2 trials, and high in 9 trials. However, the emergence of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) variants and the (slow) pace of vaccination have hampered the expected drop in cases in most parts of the world [1,2].

Measurement of plasma concentrations of ivermectin was included as an ancillary study to inform on the maximal drug levels and drug accumulation following repeated doses, on the interindividual variability and, possibly, on the association between blood drug concentration and clinical endpoints. In both non-adjusted and multivariate mixed model, a significant interaction was found between arm C and Day 7 (P-value=0.035 and 0.036, respectively). The pooled results showed that ivermectin may have a possible effect on lowering the mortality rate. Biochem J.

Safety, tolerability, and pharmacokinetics of escalating high doses of ivermectin in healthy adult subjects. To explore the possible effects of funding sources on the results of clinical trials, subgroup analysis between studies with and without funding was performed. However, our subgroup analysis based on study quality found that ivermectin had no significant effect on mortality in trials with low ROB (log OR 0.12, 95%CI 0.0.660.42; I2=00%, Tau=0.00). At the same time, interim analyses on efficacy and futility were planned comparing control and experimental arms. No significant relationship was observed between viral load changes and plasma levels of ivermectin. Detailed information on screened participants and the reasons for missing inclusions were retrieved from the screening log handled by the centres and is summarised in the study flow chart (Fig. Am J Cardiol. 2021 Oct;69(4):103309. doi: 10.1016/j.retram.2021.103309.
