COVID-19-associated meningoencephalitis treated with intravenous immunoglobulin.

ABSTRACT: A 40-year-old man presented with altered mental status after a recenthospitalisation for COVID-19 pneumonia. Cerebrospinal fluid (CSF) analysis showed lymphocytosis concerning for viral infection. The CSF PCR for SARS-CoV-2 was negative, yet this could not exclude COVID-19 meningoencephalitis. During hospitalisation, the patient's mentation deteriorated further requiring admission to the intensive care unit (ICU). Brain imaging and electroencephalogram (EEG) were unremarkable. He was, thus, treated with intravenous immunoglobulin (IVIg) for 5 days with clinical improvement back to baseline. This case illustrates the importance of considering COVID-19's impact on the central nervous system (CNS). Haematogenous, retrograde axonal transport, and the effects of cytokine storm are the main implicated mechanisms of CNS entry of SARS-CoV-2. While guidelines remain unclear, IVIg may be of potential benefit in the treatment of COVID-19-associated meningoencephalitis.

Intravenous immunoglobulin immunotherapy for coronavirus disease-19 (COVID-19).

Project description:Intravenous immunoglobulin (IVIG), a pooled normal IgG from several thousand healthy donors and one of the commonly used immunotherapeutic molecules for the management of autoimmune and inflammatory diseases, has been explored for the treatment of coronavirus disease-19 (COVID-19). Although placebo-controlled, double-blind randomised clinical trials are lacking, current data from either retrospective, case series or open-label randomised controlled trials provide an indicator that IVIG immunotherapy could benefit severe and critically ill COVID-19 patients.

Intravenous immunoglobulin therapy in COVID-19-related encephalopathy.

Project description:ObjectiveTo report on efficacy and safety of intravenous immunoglobulin (IVIg) therapy in a case series of patients with COVID-19-related encephalopathy.MethodsWe retrospectively collected data on all patients with COVID-19 hospitalized at two Italian hospitals who developed encephalopathy during disease course and were treated with IVIg.ResultsFive patients (two females, mean age 66.8 years) developed encephalopathy after a mean of 12.6 days, since the onset of respiratory/constitutional symptoms related to COVID-19. Four patients suffered severe respiratory distress, three of which required invasive mechanical ventilation. Neurological manifestations included impaired consciousness, agitation, delirium, pyramidal and extrapyramidal signs. EEG demonstrated diffuse slowing in all patients. Brain MRI showed non-specific findings. CSF analysis revealed normal cell count and protein levels. In all subjects, RT-PCR for SARS-CoV-2 in CSF tested negative. IVIg at 0.4 g/kg/die was commenced 29.8 days (mean, range: 19-55 days) after encephalopathy onset, leading to complete electroclinical recovery in all patients, with an initial improvement of neuropsychiatric symptoms observed in 3.4 days (mean, range: 1-10 days). No adverse events related to IVIg were observed.ConclusionsOur preliminary findings suggest that IVIg may represent a safe and effective treatment for COVID-19-associated encephalopathy. Clinical efficacy may be driven by the anti-inflammatory action of IVIg, associated with its anti-cytokine qualities.

A single center experience of intravenous immunoglobulin treatment in Covid-19.

Project description:BackgroundIntravenous immunoglobulins (IVIg) have been used in management of severe Covid-19. Here in this study, we report our single-center experience regarding IVIg treatment in management of severe Covid-19.Materials and methodAmong hospitalized adult Covid-19 patients between April 1 and December 31, 2020, patients with confirmed diagnosis of Covid-19 who had Brescia-COVID respiratory severity scale score ≥ 3, hyperinflammation and received IVIg treatment in addition to standard of care were retrospectively investigated. We grouped IVIg recipients into three according to reasons for IVIg administration: Group 1 patients requiring anti-inflammatory treatment but complicated with secondary infection and/or sepsis , group 2 patients with Covid-19 related complications including progressive disease refractory to other anti-inflammatory agents, myocarditis, adult multisystem inflammatory syndrome, hemophagocytic lymphohystiocytosis like syndrome and group 3 patients with other complications non-specific to Covid-19. Mortality and clinical data was compared among groups.ResultsA total of 46 IVIg recipients were enrolled. Group 1 comprised 17 (36.9%), group 2 comprised 18 (39.1%) and group 3 comprised 11 (23.9%) patients. No significant differences in means of age, gender and comorbidities were observed among groups. Mortality was significantly lower in group 3 when compared to group 1 (64.7% vs 18.2%, p = 0.016) and close to significance when compared to group 2 (50% vs 18.2% p = 0.087).ConclusionsIVIg seemed to be used mostly in severe, refractory and complicated cases in our population. As a rescue agent in severe cases refractory to other anti-inflammatory strategies, 33.7% survival rate was observed with IVIg.

COVID-19-associated meningoencephalitis complicated with intracranial hemorrhage: a case report.

Project description:The coronavirus pandemic that started in December 2019 is mainly related to clinical pictures consistent with respiratory symptoms; nevertheless, reports about neurological complications have recently appeared in the medical literature. We describe a case of a 36-year-old coronavirus-positive patient that was admitted on emergency basis; his clinical presentation included neurological symptoms such as drowsiness and mild confusion. Imaging revealed findings consistent with meningoencephalitis complicated by intracerebral hematoma and subdural hematoma. The latter was surgically evacuated after it became chronic and evidence of coronavirus was found in the fluid. Our experience confirms that neurological complications might be a likely event in COVID-19. Although uncommon, the possible occurrence of meningoencephalitis should be kept in mind by physicians involved in the management of COVID-19 patients. Early recognition of brain involvement may provide better prognosis, preventing evolution into intracerebral hemorrhagic events.

Efficacy of High-Dose Polyclonal Intravenous Immunoglobulin in COVID-19: A Systematic Review.

Project description:Although several therapeutic strategies have been investigated, the optimal treatment approach for patients with coronavirus disease (COVID-19) remains to be elucidated. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of polyclonal intravenous immunoglobulin (IVIG) therapy in COVID-19. A systematic literature search using appropriate medical subject heading (MeSH) terms was performed through Medline (PubMed), EMBASE, SCOPUS, OVID and Cochrane Library electronic databases. The main outcomes considered were mortality and safety of IVIG versus placebo/standard of care. This review was carried out in accordance with Cochrane methodology including the risk bias assessment and grading of the quality of evidence. Measures of treatment effect were mean differences (MD) together with 95% confidence intervals (CIs) for continuous outcome measures and risk ratio (RR) or MD for binary outcomes. Two reviewers independently extracted data from individual studies, and disagreements were resolved by a third reviewer. A total of 2401 COVID-19 patients from 10 studies (four randomized controlled trials (RCT) and six non-randomized controlled trials (non-RCTs)) were included in the analysis. Participants received IVIG or placebo/standard of care. The use of IVIG was not associated with a significantly reduced risk of death (RR 0.50, 95% CIs 0.18-1.36, p = 0.17 for RCTs; RR 0.95, 95% CIs 0.61-1.58, p = 0.94 for non-RCTs; low certainty of evidence). IVIG significantly reduced the length of hospital stay (MD -2.24, 95% CIs -3.20/-1.27; p = 0.00001; low certainty of evidence), although this difference was significant only for studies evaluating moderate COVID-19 patients. No significant difference was observed in the incidence of overall and serious adverse events between IVIG recipients and controls (very low certainty of evidence). The current evidence from the literature does not support the use of IVIG in COVID-19 patients.

Intravenous immunoglobulin treatment for patients with severe COVID-19: a retrospective multicentre study.

Project description:ObjectivesIntravenous immunoglobulin (IVIG) is commonly used to treat severe COVID-19, although the clinical outcome of such treatment remains unclear. This study evaluated the effectiveness of IVIG treatment in severe COVID-19 patients.MethodsThis retrospective multicentre study evaluated 28-day mortality in severe COVID-19 patients with or without IVIG treatment. Each patient treated with IVIG was matched with one untreated patient. Logistic regression and inverse probability weighting (IPW) were used to control confounding factors.ResultsThe study included 850 patients (421 IVIG-treated patients and 429 non-IVIG-treated patients). After matching, 406 patients per group remained. No significant difference in 28-day mortality was observed after IPW analysis (average treatment effect (ATE) = 0.008, 95% CI -0.081 to 0.097, p 0.863). There were no significant differences between the IVIG group and non-IVIG group for acute respiratory distress syndrome, diffuse intravascular coagulation, myocardial injury, acute hepatic injury, shock, acute kidney injury, non-invasive mechanical ventilation, invasive mechanical ventilation, continuous renal replacement therapy and extracorporeal membrane oxygenation except for prone position ventilation (ATE = -0.022, 95% CI -0.041 to -0.002, p 0.028).DiscussionIVIG treatment was not associated with significant changes in 28-day mortality in severe COVID-19 patients. The effectiveness of IVIG in treating patients with severe COVID-19 needs to be further investigated through future studies.

Effectiveness of intravenous immunoglobulin for children with severe COVID-19: a rapid review.

Project description:BackgroundIntravenous immunoglobulin (IVIG) is usually used as supportive therapy, but the treatment of COVID-19 by IVIG is controversial. This rapid review aims to explore the clinical effectiveness and safety of IVIG in the treatment of children with severe COVID-19.MethodsWe systematically searched the literature on the use of IVIG in patients with COVID-19, severe acute respiratory syndrome (SARS) or Middle East respiratory syndrome (MERS), including both adults and children. We assessed the risk of bias and quality of evidence and reported the main findings descriptively.ResultsA total of 1,519 articles were identified by initial literature search, and finally six studies met our inclusion criteria, included one randomized controlled trial (RCT), four case series and one case report involving 198 patients. One case series showed the survival of COVID-19 patients with acute respiratory distress syndrome (ARDS) was not improved by IVIG. One case report showed high-dose IVIG could improve the outcome of COVID-19 adults. Three observational studies showed inconsistent results of the effect of IVIG on SARS patients. One RCT showed that IVIG did not reduce mortality or the incidence of nosocomial infection in adults with severe SARS. The quality of evidence was between low and very low.ConclusionsThe existing evidence is insufficient to support the efficacy or safety of IVIG in the treatment of COVID-19.

Production of hyperimmune anti-SARS-CoV-2 intravenous immunoglobulin from pooled COVID-19 convalescent plasma.

Project description:Background: This study assesses the feasibility of producing hyperimmune anti-COVID-19 intravenously administrable immunoglobulin (C-IVIG) from pooled convalescent plasma (PCP) to provide a safe and effective passive immunization treatment option for COVID-19. Materials & methods: PCP was fractionated by modified caprylic acid precipitation followed by ultrafiltration/diafiltration to produce hyperimmune C-IVIG. Results: In C-IVIG, the mean SARS-CoV-2 antibody level was found to be threefold (104 ± 30 cut-off index) that of the PCP (36 ± 8.5 cut-off index) and mean protein concentration was found to be 46 ± 3.7 g/l, comprised of 89.5% immunoglobulins. Conclusion: The current method of producing C-IVIG is feasible as it uses locally available PCP and simpler technology and yields a high titer of SARS-CoV-2 antibody. The safety and efficacy of C-IVIG will be evaluated in a registered clinical trial (NCT04521309).

Development and characterization of anti-SARS-CoV-2 intravenous immunoglobulin from COVID-19 convalescent plasma.

Project description:Background: The authors describe the developmental process of intravenous anti-COVID-19 hyperimmune immunoglobulin from anti-SARS-CoV-2 neutralizing antibody-containing plasma. Furthermore, the authors investigated its safety and protective activity in animal models. Materials & methods: The manufacturing process included standard ethanol fractionation, chromatographic purification steps and virus removal or inactivation. Results: The authors produced pure and safe immunoglobulin for intravenous administration, with 98.1 ± 6.5 mg/ml protein content, of which 97.6 ± 0.7% was IgG. The concentration factor of SARS-CoV-2 neutralizing antibodies was 9.4 ± 1.4-times. Safety studies in animals showed no signs of acute/chronic toxicity or allergenic or thrombogenic properties. Intravenous anti-COVID-19 hyperimmune immunoglobulin protected immunosuppressed hamsters against SARS-Cov-2. Conclusion: The obtained results can allow the start of clinical trials to study the safety and efficacy in healthy adults.

Efficacy of IVIG (intravenous immunoglobulin) for corona virus disease 2019 (COVID-19): A meta-analysis.

Project description:BackgroundThe benefit of IVIG (Intravenous Immunoglobulin) therapy for COVID-19 remains controversial. We performed a meta-analysis to investigate the efficacy of IVIG treatment in patients with COVID-19.MethodsWe searched articles from Web of Science, PubMed, Embase, the Cochrane Library, MedRxiv between 1 January 2020 and February 17, 2021. We selected randomized clinical trials and observational studies with a control group to assess the efficiency of IVIG in treating patients with COVID-19. Subjects were divided into 'non-severe', 'severe' and 'critical' three subgroups based on the information of the study and the World Health Organization (WHO) definition of severity. We pooled the data of mortality and other outcomes using either a fixed-effect model or a random-effects model.ResultsOur meta-analysis retrieved 4 clinical trials and 3 cohort studies including 825 hospitalized patients. The severity of COVID-19 is associated with the efficiency of IVIG. In critical subgroup, IVIG could reduce the mortality compared with the control group [RR = 0.57 (0.42-0.79, I2 = 025%). But there was no significant difference in the severe or non-severe subgroups.ConclusionIVIG has demonstrated clinical efficacy on critical ill patients with COVID-19. There may be a relationship between the efficacy of IVIG and the COVID-19 disease severity. Well-designed clinical trials to identify the clinical and biochemical characteristics in COVID-19 patients' population that could benefit from IVIG are warranted in the future.
