Relapses in the Guillain-Barré syndrome after treatment with intravenous immune globulin or plasma exchange

Plasma exchange (PE) versus intravenous immunoglobulin (IVIG) for the treatment of Guillain-Barré syndrome (GBS) in patients with severe symptoms: A systematic review and meta-analysis

Background and purpose

Guillain- Barré syndrome (GBS) is a neuropathic condition that leads to the rapid development of impairments and is characterized by weakness and numbness or tingling sensation in the legs and arms and sometimes loss of movement and feeling in the legs, arms, upper body, and face. Currently, the cure for the disease is yet to be developed. However, treatment options such as intravenous immunoglobulin (IVIG) and plasma exchange (PE) have been used to minimize the symptoms and duration of the disease. Therefore, this systematic review and meta-analysis compared the efficacy of IVIG and PE in treating GBS patients with severe symptoms.

Methodology

Six electronic databases, including PubMed, Embase, Scopus, ScienceDirect, Medline, and Google scholar, were scoured for articles related and relevant to our research. Additionally, more studies were obtained through the reference lists of the studies retrieved from these electronic databases. Quality assessment and statistical data analysis were conducted using Review Manager software (RevMan 5.4.1).

Results

The search for relevant articles resulted in 3253 articles, of which only 20 were included for review in the current study. A sub-group analysis indicated no significant difference in the curative effect (Hughes score reduces by at least one score 4 weeks after GBS treatment; OR: 1.00; 95% CI: 0.66-1.52; p = 1.00 and Achieving grade 0 or 1 on Hughes scale; OR: 1.03; 95% CI: 0.27-3.94; p = 0.97). Similarly, the statistical showed that the difference in length of hospitalization and duration of mechanical ventilation was insignificant between the IVIG and PE group (Standard Mean Difference (SMD): -0.45; 95% CI: -0.92, 0.02; I² = 91%; p = 0.06 and SMD: -0.54; 95% CI: -1.67, 0.59; I² = 93%; p = 0.35, respectively). Moreover, the meta-analysis did not find any significant difference in the risk of GBS relapse (RR: 0.47; 95% CI: 0.20-1.14; p = 0.10) and risk of complications related to the treatment regimens (RR: 1.03; 95% CI: 0.71-1.48; p = 0.89). However, the statistical analysis of outcomes from 3 studies showed that the risk of discontinuation was significantly lower in the IVIG group than in the PE group (RR: 0.22; 95% CI: 0.06-0.88; p = 0.03).

Conclusion

Our study suggests that IVIG and PE have similar curative effects. Similarly, IVIG seems easier to use and thus can be preferred for treating GBS.

Treatment related fluctuation and response to intravenous immunoglobulin therapy in post COVID-19 Guillain-Barre syndrome

Treatment related fluctuation (TRF) poses a special challenge in the treatment of Guillain-Barre syndrome (GBS). Many cases of GBS following COVID-19 infection have been reported in literature till date, but treatment related fluctuation (TRF) in post COVID-19 GBS has not been reported till date. We report a 35-year-old male patient who developed GBS following COVID-19 infection and had TRF after intravenous immunoglobulin (IV-IG) therapy. He required ventilator support but repeat IV-IG therapy led to complete recovery. Significant proximal muscle involvement, cranial nerve palsy, no antecedent diarrhea and absence of anti-GM1 antibodies are important predictors of TRF in GBS and need to be recognized early in the course of this illness. Early recognition of TRF and differentiating it from other forms of immune mediated neuropathy such as acute onset chronic inflammatory demyelinating polyradiculoneuropathy (A-CIDP) are important for prognostication and management.

Readmissions After Guillain-Barre Syndrome: Nationally Representative Data

OBJECTIVES

We aimed to obtain nationally representative data on hospital readmission rates after Guillain-Barre syndrome (GBS).

METHODS

International Classification of Disease, Ninth Revision codes from the 2013 National Readmissions Database identified adult GBS admissions, comorbidities, and readmission diagnoses. Logistic regression estimated odds ratios (ORs) for readmission.

RESULTS

Of 2109 GBS admissions identified, 20.8% were readmitted within 1 year and 12.2% within 30 days. Age did not predict readmission. Plasmapheresis use showed a nonsignificant trend toward readmission versus intravenous immunoglobulin use [OR 1.43, 95% confidence interval (CI) 1.00-2.051, P = 0.050]. Respiratory failure (OR 1.70, 95% CI 1.23-2.35, P = 0.0014), heart failure (OR 2.14, 95% CI 1.25-3.66, P = 0.0057), and renal failure (OR 2.00, 95% CI 1.20-3.32, P = 0.0078) predicted readmission. Top readmission diagnoses included GBS or chronic inflammatory demyelinating polyneuropathy (42.0%) and sepsis (3.5%).

CONCLUSIONS

One-fifth of GBS patients were readmitted within 1 year. Comorbid illnesses and respiratory complications increased a readmission risk but age did not.

Treatment-related Fluctuations in Guillain Barre Syndrome and the Conundrum of Additional Cycles of Plasmapheresis

Introduction:

In Guillain Barre syndrome (GBS), worsening of weakness or disability after initial period of recovery or stabilization is described as treatment-related fluctuations (TRF).

Aim:

This study aims to describe the clinical characteristics and outcome of six patients with GBS and TRF.

Patients and Methods:

Six patients with GBS fulfilling NINCDS criteria, evaluated at a tertiary care university hospital during 2008–2017, were diagnosed to have TRF. They form the basis of this report.

Results:

All patients were men and their mean age was 40 years. At presentation, mean duration of illness was 15 days; the illness had plateaued in three and progressive in other three patients. Two of the four patients had variant GBS. Initially, five patients were treated with large volume plasmapheresis (LVPP) and one patient with methyl prednisolone. At 17–28 days after disease onset, three patients developed new neurologic deficits (bilateral facial paresis in two; paralytic ileus in one). Other three patients with worsening of limb weakness (medical research council sum score of >5) and disability (Hughes disability grade by ≥1) fulfilled Kleyweg's criteria for TRF. All the six patients were treated with the completion of five cycles or additional cycles of LVPP.

Conclusion:

Awareness about TRF is essential for correct diagnosis and management of patients with GBS.

Treatment-related fluctuation in Guillain-Barre syndrome

Guillain-Barre syndrome (GBS) is usually a monophasic illness but relapses occur. A 55-year-old female with hypertension and vitiligo presented with acute inflammatory demyelinating polyradiculoneuropathy. She improved with immunoglobulin treatment started on day 6 of illness, but relapsed on day 14 warranting repeat immunoglobulin therapy. Thereafter recovery was complete. Her relapse was due to treatment-related fluctuation (TRF). TRF is improvement in the GBS disability scale of at least one grade after completion of immunotherapy followed by worsening of the disability scale of at least one grade within the first 2 months after disease onset. Recurrent GBS and chronic inflammatory demyelinating polyradiculoneuropathy were excluded. During the peak of the illness ANA titres were transiently high. The presence of other medical conditions, predominant proximal weakness and the absence of preceding diarrhea are predictors for TRF seen in this patient. Early treatment and evidence of ongoing immune activation have contributed toward TRF.

Recurrence of childhood Guillain-Barré syndrome after a long asymptomatic interval: a case report

We present a patient who rapidly developed flaccid paralysis in all 4 limbs on 2 separate occasions 19 years apart. Each episode was accompanied by a respiratory failure that required intubation. Both times, clinical response to immunotherapy was favorable with a near complete recovery. Clinical course, laboratory and electrodiagnostic findings, and favorable response to therapy suggest 2 separate attacks of Guillain-Barré syndrome. The reported case adds to a small series of cases of recurrent Guillain-Barré syndrome after a long asymptomatic period. In such cases, the distinction from chronic inflammatory demyelinating polyradiculoneuropathy should be made.

Current Therapeutic Options in Severe Guillain-Barre?? Syndrome

The classical form of Guillain-Barré syndrome (GBS) refers to an acute monophasic demyelinating motor and sensory polyneuropathy characterized by symmetric ascending flaccid weakness, along with sensory impairment and, less commonly, autonomic perturbations. Pure motor axonal forms, axonal motor, and sensory forms, as well as pure autonomic forms, have also been identified. A complex immune-mediated process leads to segmental demyelination accompanied with axonal involvement in protracted cases. Establishing strategies of immunomodulation may therefore halt and even reverse the harmful autoimmune insult to peripheral nerves. The present article reviews the current immunomodulatory options in severe GBS. A recent Cochrane meta-analysis of 6 randomized studies showed no significant improvement using corticosteroids, including either oral or intravenous methylprednisolone. Combined methylprednisolone and immunoglobulins shortened the time lapse to regain independent walking. Plasmapheresis (PE) was the first effectively proven method of immunomodulation, followed by intravenous immunoglobulins (IVIG). Both methods are comparable in their beneficial effect and were used either separately or in combination, but PE was more frequently associated with severe adverse effects requiring cessation of therapy, including a bleeding diathesis. In addition, PE is feasible only in major referral centers requiring the appropriate equipment and trained personnel. In addition, younger children may be at risk for bleeding after insertion of wide catheters. Therefore, in cases of severe GBS, IVIG is recommended as the first-line drug using a total empiric dose of 2 g/kg administered over 2 consecutive days, especially in children proven highly effective with negligible adverse effects. In protracted cases, the addition of intravenous corticosteroids to IVIG should be considered, which may shorten the duration to regain independent walking. If such therapy fails, PE should be applied using centrifugal blood separators with 5% albumin as the substitute solution.

Intravenously administered immunoglobulin in the treatment of childhood Guillain-Barré syndrome: a randomized trial

OBJECTIVE

To determine the optimal treatment for childhood Guillain-Barré syndrome (GBS).

METHODS

We performed a randomized, multicenter study of GBS according to international diagnostic criteria. In study 1 (early treatment), children able to walk unaided for 5 meters were randomized for 1 g/kg intravenously administered immunoglobulin (IVIG) over 2 days or no treatment. The primary outcome measure was the degree of disability at nadir. In study 2 (treatment for severe GBS), children unable to walk 5 meters unaided were randomized for 1 g/kg IVIG over 2 days or 0.4 g/kg IVIG over 5 days. The primary outcome measure was the number of days needed to regain the ability to walk unaided. Children randomized for no treatment in study 1 could enter study 2 if loss of unaided walking occurred.

RESULTS

Ninety-five children with GBS were registered in 40 months. Twenty-one children were randomized in study 1 and 51 in study 2 (5 after deterioration in study 1). Twenty-eight children were not randomized for various reasons. Eleven of 21 patients in study 1 lost the ability to walk unassisted and 6 were bedridden, with no statistically significant difference between the children initially randomized for treatment versus no treatment. Recovery occurred faster in the group randomized for early treatment. In study 2, recovery did not differ significantly between the children treated for 2 days versus 5 days (median time to unaided walking: 19 days vs 13 days). Secondary transient deterioration in the disability score occurred more frequently in the group with the 2-day regimen than in the group treated for 5 days (5 of 23 patients vs 0 of 23 patients). Multivariate analysis with Cox regression showed that disease severity at the nadir was the only prognostic factor for recovery.

CONCLUSIONS

Treatment with IVIG before loss of unaided walking did not give rise to a less severe course, but recovery occurred somewhat faster. However, given the small number of patients, the power of this conclusion is low. For treatment after loss of unaided walking, there was no significant difference in the effectiveness of 2 g/kg IVIG administered over 2 days versus 5 days. Early "relapses" occurred more frequently after the shorter treatment regimen.

Antiglycolipid antibodies in Guillain-Barré syndrome and related diseases: Review of clinical features and antibody specificities

Guillain-Barré syndrome (GBS) is an acute inflammatory polyradiculoneuropathy that usually develops following a respiratory or intestinal infection. Although the pathogenic mechanisms of GBS have not been fully established, both humoral and cell-mediated immune factors have been shown to contribute to the disease process. Several antiglycosphingolipid (anti-GSL) antibodies have been found in the sera of patients with GBS or related diseases. Measurements of these antibody titers are very important in the diagnosis of GBS and in evaluating the effectiveness of treatments in clinical trials. The most common treatment strategies for these disorders involve plasmapheresis and the use of steroids for reducing anti-GSL antibody titers to ameliorate patients' clinical symptoms. Administration of intravenous immunoglobulin may also be beneficial in the treatment of neuropathies by suppressing the immune-mediated processes that are directed against antigenic targets in myelin and axons. In certain demyelinating neuropathies, the destruction or malfunctioning of the blood-nerve barrier, which results in the leakage of circulating antibodies into the peripheral nerve parenchyma, has been considered to be an initial step in development of the disease process. In addition, anti-GSL antibodies, such as anti-GM1, may cause nerve dysfunction and injury by interfering with the ion channel function at the nodes of Ranvier, where carbohydrate epitopes of glycoconjugates are located. These malfunctions thus contribute to the pathogenic mechanisms of certain demyelinating neuropathies.

The use of intravenous immunoglobulin in the treatment of autoimmune neuromuscular diseases: evidence-based indications and safety profile

Intravenous immunoglobulin (i.v.Ig) has multiple actions on the immunoregulatory network that operate in concert with each other. For each autoimmune neuromuscular disease, however, there is a predominant mechanism of action that relates to the underlying immunopathogenetic cause of the respective disorder. The best understood actions of i.v.Ig include the following: (a) modulation of pathogenic autoantibodies, an effect relevant in myasthenia gravis (MG), Lambert-Eaton myasthenic syndrome (LEMS), Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyneuropathy (CIDP), and stiff-person syndrome (SPS); (b) inhibition of complement activation and interception of membranolytic attack complex (MAC) formation, an action relevant to the complement-mediated mechanisms involved in GBS, CIDP, MG, and dermatomyositis (DM); (c) modulation of the inhibitory or activation Fc receptors on macrophages invading targeted tissues in nerve and muscle, as seen in CIDP, GBS, and inflammatory myopathies; (d) down-regulation of pathogenic cytokines and adhesion molecules; (e) suppression of T-cell functions; and (f) interference with antigen recognition. Controlled clinical trials have shown that i.v.Ig is effective as first-line therapy in patients with GBS, CIDP, and multifocal motor neuropathy (MMN), and as second-line therapy in DM, MG, LEMS, and SPS. In paraproteinemic IgM anti-MAG (myelin-associated glycoprotein) demyelinating polyneuropathies and inclusion body myositis (IBM), the benefit is variable, marginal, and not statistically significant. i.v.Ig has a remarkably good safety record for long-term administration, however, the following side effects have been observed: mild, infusion-rate-related reactions, such as headaches, myalgia, or fever; moderate but inconsequential events, such as aseptic meningitis and skin rash; and severe, but rare, complications, such as thromboembolic events and renal tubular necrosis. Future studies are needed to (a) find the appropriate dose and frequency of infusions that maintain a response; (b) address pharmacoeconomics, comparing the high cost of i.v.Ig to the cost of the other therapies, which, although less expensive, cause significantly more long-term side effects; (c) determine why some patients respond better than others; and (d) examine the merits of combining i.v.Ig with other immunosuppressive drugs.

Treatment approaches for Guillain-Barré syndrome and chronic inflammatory demyelinating polyradiculoneuropathy

GBS and CIDP are important treatable forms of acquired peripheral neuropathies. GBS is a heterogeneous disorder representing at least five different entities. Three are predominantly motor: AIDP, AMSAN, and AMAN. Fisher syndrome and acute panautonomic neuropathy are other variants. Treatment for all of these conditions is the same and includes either plasma exchange or intravenous immunoglobulin. There is no indication that Guillain-Barré patients respond to corticosteroids. At the present time, it is uncertain if CIDP represents one or more disorders. Evidence favors a syndrome composed of more than one entity accounting for (1) clinical variations from subject-to-subject, ranging from symmetrical to focal neurologic deficits; (2) course variations from slowly progressive to step-wise, to relapsing; and, (3) laboratory variations in nerve conduction studies, spinal fluid protein, and nerve biopsy findings. CIDP patients respond to corticosteroids in contrast to those with GBS. CIDP improves with intravenous immunoglobulin and plasma exchange, paralleling the findings in GBS. Specific regimens of treatment for both GBS and CIDP are presented in this article and considerations that might influence one treatment regimen over another are discussed.

Intravenous immunoglobulin in the treatment of autoimmune neuromuscular diseases: present status and practical therapeutic guidelines

This review summarizes the current status of intravenous immunoglobulin (IVIg) in the treatment of autoimmune neuromuscular disorders and the possible mechanisms of action of the drug based on work in vivo, in vitro, and in animal models. Supply of idiotypic antibodies, suppression of antibody production, or acceleration of catabolism of immunoglobulin G (IgG) are relevant in explaining the efficacy of IVIg in myasthenia gravis (MG), Lambert-Eaton myasthenic syndrome (LEMS), and antibody-mediated neuropathies. Suppression of pathogenic cytokines has putative relevance in inflammatory myopathies and demyelinating neuropathies. Inhibition of complement binding and prevention of membranolytic attack complex (MAC) formation are relevant in dermatomyositis (DM), Guillain-Barré syndrome (GBS), and MG. Modulation of Fc receptors or T-cell function is relevant in chronic inflammatory demyelinating polyneuropathy (CIDP), GBS, and inflammatory myopathies. The clinical efficacy of IVIg, based on controlled clinical trials conducted in patients with GBS, CIDP, multifocal motor neuropathy (MMN), DM, MG, LEMS, paraproteinemic IgM anti-myelin-associated glycoprotein (anti-MAG) demyelinating polyneuropathies, and inclusion body myositis is summarized and practical issues related to each disorder are addressed. The present role of IVIg therapy in other disorders based on small controlled or uncontrolled trials is also summarized. Finally, safety issues, risk factors, adverse reactions, spurious results or serological tests, and practical guidelines associated with the administration of IVIg in the treatment of neuromuscular disorders are presented.

Treatment of immune-mediated inflammatory neuropathies

Experimental models have suggested potential new treatments for human inflammatory neuropathy, but current practice is largely based on empirical trials. Evidence from randomized trials supports the use of intravenous immunoglobulin in Guillain-Barré syndrome, chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and multifocal motor neuropathy with conduction block (MMNCB). In Guillain-Barré syndrome and CIDP intravenous immunoglobulin is equivalent to but more convenient than plasma exchange. In MMNCB adequate comparative studies of intravenous immunoglobulin and plasma exchange have not been performed. Corticosteroid treatment is beneficial in CIDP, but not in Guillain-Barré syndrome and may worsen MMNCB. More randomized trials and systematic reviews are needed to improve the evidence base for clinical practice.
