Guillain-Barré syndrome (GBS) Update

By

Guillain-Barré syndrome (GBS) is a rare neurological disorder in which the body's immune system mistakenly attacks the peripheral nervous system. The peripheral nervous system consists of the nerves outside the brain and spinal cord. This condition can lead to weakness, numbness, and in some cases, paralysis.

Key Diagnostic Tests

Spinal Tap (Lumbar Puncture): A doctor takes a small sample of cerebrospinal fluid (CSF) from your lower back. For GBS, the fluid usually shows high protein levels but a normal white blood cell count. Doctors call this Albuminocytologic dissociation.

Nerve Conduction Studies (NCS): Taped skin electrodes send mild electric shocks to measure how fast signals travel through your nerves. GBS slows down these signals due to nerve damage.

Checking specific markers: Tests like serum creatine phosphokinase (CPK) help rule out primary muscle diseases (myopathy).

Electromyography (EMG): Thin needle electrodes go into your muscles to measure their electrical activity and check for nerve damage.

Blood and Routine Lab Tests

Routine blood panels do not diagnose GBS directly. Instead, doctors order them to rule out other illnesses that cause muscle weakness:

• Electrolytes and Glucose: Check for metabolic imbalances.

• Kidney and Liver Function: Assess overall organ health.

• Complete Blood Count (CBC): Look for signs of infection.

• Anti-GQ1b Antibodies: Used only if the doctor suspects the Miller Fisher variant of GBS.

 

Here are some key points about Guillain-Barré syndrome:

  1. Symptoms: GBS often begins with weakness and tingling in the legs, which can progress to affect the arms and upper body. Muscle weakness or paralysis can become severe, and in some cases, individuals may have difficulty breathing or experience life-threatening complications.

  2. Causes: The exact cause of GBS is not fully understood, but it is often preceded by a viral or bacterial infection. It is believed that the immune system's response to the infection may trigger an autoimmune response, damaging the nerves.

  3. Variants: There are several variants of Guillain-Barré syndrome, including acute inflammatory demyelinating polyneuropathy (AIDP), Miller Fisher syndrome, and others. These variants have slightly different clinical features and may affect different nerves.

  4. Diagnosis: GBS is typically diagnosed based on clinical symptoms and various tests, such as nerve conduction studies and lumbar puncture (spinal tap). These tests can help confirm the presence of nerve damage and inflammation.

  5. Treatment: There is no cure for GBS, but early intervention is important. Treatment often involves hospitalization to monitor and manage complications. Intravenous immunoglobulin (IVIG) or plasmapheresis (plasma exchange) are common treatments that aim to reduce the immune system's attack on the nerves and promote recovery.

  6. Prognosis: The prognosis for individuals with Guillain-Barré syndrome varies. Many people experience a gradual recovery, while others may have residual weakness or long-term neurological complications. Some individuals may experience a rapid onset of symptoms and require more intensive medical intervention.

  7. Recovery: Recovery from GBS can take weeks to months, and physical therapy is often necessary to regain strength and function. Some individuals may experience long-term neurological issues, while others can fully recover.

"As of March 8, 2025, the total number of Guillain–Barré syndrome cases in Pune was 225, with 197 confirmed diagnoses and 28 suspected cases, and can be considered as one of the largest Guillain–Barré syndrome outbreaks." 

It's essential for individuals with suspected GBS to seek prompt medical attention, as early diagnosis and treatment can improve outcomes. While Guillain-Barré syndrome can be a serious and potentially life-threatening condition, many people do recover with appropriate medical care and rehabilitation. Treatment and management should be discussed with a healthcare professional.

Schnitzler Syndrome: A Rare Autoinflammatory Disorder

By
Schnitzler syndrome is a rare, chronic autoinflammatory disease characterized by chronic urticaria (hives), recurrent fever, joint pain, and monoclonal gammopathy (abnormal proteins in the blood). First described by Dr. Liliane Schnitzler in 1972 , this condition is often misdiagnosed, leading to years of untreated symptoms before a correct diagnosis is made. The case report, " A 58-Year-Old Woman With Urticaria, Fever, and Joint Pain " , describes a case that closely aligns with my own experience with this challenging disorder. Key Features of Schnitzler Syndrome Schnitzler syndrome presents with a characteristic set of symptoms, though not all patients experience them in the same way: Chronic Urticaria (Hives) – Persistent, non-itchy or mildly itchy red patches that do not respond to antihistamines. Monoclonal Gammopathy (IgM or IgG type) – Abnormal monoclonal immunoglobulin detected in the blood (most commonly IgM ). Recurrent Fever – Unexplained fever episodes, often...

Dysferlin Protein: Key Roles, Genetic Locations

By
Image
The purpose of this article is to share and discuss the details of a new discovery, which is highlighted within: CRISPR-Cas9: A Breakthrough Tool to Repair the DYSF Gene The dysferlin protein plays an essential role in maintaining the integrity of muscle cell membranes, particularly in tissues that endure significant mechanical stress, such as skeletal and cardiac muscles . Encoded by the DYSF gene , dysferlin is indispensable for repairing damaged cell membranes after injury caused by muscle contraction or external forces. This article explores the main locations where dysferlin is produced, its role in muscle repair, and supportive nutritional and therapeutic strategies for individuals with dysferlin deficiency, such as those affected by dysferlinopathies (e.g., Limb-Girdle Muscular Dystrophy Type 2B or Miyoshi Myopathy). Currently, there is no definitive answer as to why the severity of dysferlin protein expression or depletion varies. Do pathogens play a role in the methylation o...

Acute Flaccid Myelitis (AFM): Understanding the “Polio-like” Illness Affecting the Spinal Cord

By
Acute flaccid myelitis (AFM) is a rare but serious neurological disorder that primarily affects children and results in sudden weakness or paralysis in the limbs. Often referred to as a “polio-like” illness, AFM has drawn growing attention over the past decade due to its similarities with poliomyelitis and its seasonal spikes in reported cases. While AFM remains uncommon, its potential severity—and the uncertainty surrounding its causes—make it an important condition for clinicians, parents, and public health officials to understand. What Is Acute Flaccid Myelitis? AFM is a condition that affects the gray matter of the spinal cord , where it damages motor neurons responsible for muscle movement. This leads to acute, flaccid paralysis , meaning muscles become limp and weak, often without warning. The condition can progress rapidly, and in some cases, the weakness can become long-lasting or even permanent. Although its symptoms resemble those of poliovirus infection, AFM is not cau...

Very Long-Chain Fatty Acids (VLCFAs) X-ALD and Spinal Muscular Atrophy (SMA): Exploring the Connection

By
Image
Introduction: White Brain Matter, VLCFAs, and X-ALD X-linked Adrenoleukodystrophy (X-ALD) is a rare inherited metabolic disorder and a major cause of progressive neurodegeneration in children—sometimes referred to as “childhood dementia.” Across related conditions, prevalence can range from approximately 1 in 2,000 to 1 in 500,000 newborns. Among its forms, childhood cerebral X-ALD is the most severe, marked by rapid inflammatory demyelination in the brain and often fatal outcomes if not treated early. At the core of X-ALD is a disruption in the metabolism of Very Long-Chain Fatty Acids (VLCFAs). Normally, these fatty acids are broken down in peroxisomes—specialized structures within cells that help maintain metabolic balance. In X-ALD, a mutation in the ABCD1 gene impairs this function, causing VLCFAs to accumulate, particularly in the white matter of the brain, spinal cord, and adrenal glands. This accumulation leads to demyelination, adrenal insufficiency (Addison’s disease), a...

Polio and Post-Polio Syndrome (PPS): Summary and Key Insights

By
Image
Abstract Post-Polio Syndrome (PPS) develops in some survivors of paralytic poliomyelitis decades after recovery and is characterized by new or progressive muscle weakness, fatigue, pain, and reduced endurance. The prevailing pathophysiological model attributes PPS primarily to the gradual deterioration of enlarged motor units formed through compensatory axonal sprouting after the initial poliovirus (PV) infection. Although immune dysregulation and chronic systemic inflammation have been investigated as potential mechanisms, current evidence does not support classifying PPS as a primarily dysimmune or chronically inflammatory disorder. Nevertheless, the possible persistence of poliovirus-derived material and its biological significance remain subjects of investigation. Evidence for viral persistence has been reported in subsets of patients with PPS. In one study of 47 patients, elevated anti-poliovirus IgM antibodies were detected in some individuals, with titers reaching 1:250 compared...

Is ME CFS connected to Spinal Muscular Atrophy (SMA) or Post Polio?

By
Image
My Journey Toward Understanding Spinal Muscular Atrophy (SMA) Today, I better understand why Spinal Muscular Atrophy (SMA) received so little attention, particularly during the 1950s. This complex and debilitating genetic disorder was poorly understood, and patients’ symptoms could easily be minimized, misinterpreted, or dismissed. Even today, SMA can present significant diagnostic challenges, particularly in adults with complex medical histories. In my own experience, comprehensive investigations into the underlying cause of progressive muscle weakness were not always pursued. A Long and Complicated Diagnostic Journey In 2008, while being investigated for permanent adrenal insufficiency, an MRI ordered by my endocrinologist unexpectedly revealed Chiari Malformation II .  I underwent surgery in 2009, but unfortunately, my symptoms did not improve. In 2010, a DNA test identified a genetic marker involving the ACTN3 gene . Further information about ACTN3 and its possible relation...

Stevens–Johnson Syndrome and Toxic Epidermal Necrolysis

By
Image
Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening diseases that affect the skin and mucous membranes. They are usually caused by medications, especially antibiotics, antiepileptic drugs, and pain relievers, although infections can also trigger them. SJS involves less than 10% skin detachment, TEN involves more than 30%, and intermediate cases are called SJS/TEN overlap. A person with SJS often encounters primary care providers who have limited understanding of this life-threatening illness and may prescribe inappropriate medications.   The disease develops through a severe immune reaction in which cytotoxic T cells and natural killer cells attack keratinocytes, leading to widespread skin cell death. Several pathways are involved, including granzyme, Fas/FasL, perforin, and inflammatory cytokines such as TNF-α, IL-6, and IFN-γ. Genetic susceptibility also plays an important role, as certain HLA alleles are linked to higher risk in spe...

The Impact of Acids on Muscular and Vascular Systems: Potential Negative Outcomes

By
This is ongoing research, and updates will be included as soon as they become available. A kidney transplant recipient with acute SARS-CoV-2 infection developed rhabdomyolysis and severe acute kidney injury (AKI) . A muscle biopsy confirmed findings consistent with immune-mediated necrotising myositis. Acid exposure and acid–base imbalances may profoundly affect the muscular and vascular systems. Strong acids from external sources, such as industrial chemicals, can cause corrosive tissue damage, while internal disturbances associated with metabolic disorders may disrupt cellular function and contribute to systemic complications. This article explores the potential effects of external acid exposure and internal acid–base disturbances on muscular and vascular health, including those associated with metabolic or genetic conditions. Because susceptibility to ME/CFS and complications following COVID-19 varies among individuals, further research may help determine whether genetic variant...

Research Proposal: Investigating Cortical Homunculus Dysfunction and Pain Sensitivity Mapping in ME/CFS and Post-COVID Conditions

By
Image
  1. Background and Rationale The cortical homunculus represents the somatotopic organization of the human body within the primary motor and sensory cortices. This organization reflects the unequal distribution of neural resources, with highly sensitive or finely controlled body regions (e.g., hands, lips, face) occupying disproportionately large cortical areas. Originally described by Wilder Penfield and Edwin Boldrey , this model remains central to understanding how the brain processes sensory input and motor output. ME/CFS and post-COVID conditions frequently involve neurological symptoms such as localized pain, hypersensitivity (hyperalgesia or allodynia), and muscle weakness. While current research focuses on neuroinflammation and autonomic dysfunction, the potential role of somatotopic cortical disruption—particularly involving pain sensitivity—remains insufficiently explored. Given the close functional relationship between the sensory homunculus and the supplementary mot...
