Complement activation plays a critical role in the pathogenesis of Guillain-Barré syndrome (GBS), a debilitating immune-mediated neuropathy. Mannose-binding lectin (MBL) is a complement activation factor of lectin pathway which as genetic host factor may influence the susceptibility or severity of GBS. We investigated the frequency of MBL2 promoter (- 550H/L and - 221X/Y) and functional region (exon 1 A/O) polymorphisms and their association with disease susceptibility, clinical features and serum MBL among GBS patients (n = 300) and healthy controls (n = 300) in Bangladesh.

Article Synopsis
  • The study looked at a score called mEGOS that helps predict if people with a sickness called Guillain-Barré syndrome (GBS) will be able to walk on their own or not.
  • Researchers used information from 1,500 patients from a big study to see if mEGOS worked well for people from different regions and made some improvements to it.
  • The updated score showed good results in different areas, but some places had better or worse outcomes than expected, and they found that things like age and how weak someone’s limbs were were important for predicting problems.

The epidemiology, clinical characteristics, management and outcome of Guillain-Barré syndrome (GBS) differ between low-income and middle-income countries (LMIC) and high-income countries (HIC). At present, limited data are available on GBS in LMIC and the true incidence of GBS in many LMIC remains unknown. Increased understanding of GBS in LMIC is needed because poor hygiene and high exposure to infections render populations in LMIC vulnerable to GBS outbreaks.

Article Synopsis
  • Guillain-Barré syndrome (GBS) has two main subtypes: acute inflammatory demyelinating polyneuropathy (AIDP) and acute motor axonal neuropathy (AMAN), with early nerve excitability changes being key indicators of subtype.
  • A study involving 19 patients from The Netherlands and 22 from Bangladesh used compound muscle action potential (CMAP) scans within days of weakness onset to assess nerve function.
  • Results showed distinct CMAP scan patterns between AMAN and AIDP patients, particularly in stimulus intensity, suggesting that early CMAP scans can help identify GBS subtype early on.

Guillain-Barré syndrome is a heterogeneous disorder regarding the clinical presentation, electrophysiological subtype and outcome. Previous single country reports indicate that Guillain-Barré syndrome may differ among regions, but no systematic comparative studies have been conducted. Comparative studies are required to identify factors determining disease susceptibility, variation and prognosis, and to improve diagnostic criteria.

Guillain-Barré syndrome (GBS) is an autoimmune disorder of the peripheral nervous system triggered by molecular mimicry between pathogen lipopolysaccharides and host nerve gangliosides. Polymorphisms in the Fas receptor (FAS) and Fas ligand (FASL) genes may potentially alter the elimination of autoreactive immune cells and affect disease susceptibility or disease severity in GBS. We detected single nucleotide polymorphisms (SNPs) in FAS (-1377G/A and -670A/G) and FASL (-843C/T) in a prospective cohort of 300 patients with GBS and 300 healthy controls from the Bangladeshi population.

Background: In Bangladesh, most patients with Guillain-Barré syndrome (GBS) cannot afford standard treatment with intravenous immunoglobulin (IVIG) or a standard plasma exchange (PE) course, which partly explains the high rate of mortality and residual disability associated with GBS in this country. Small volume plasma exchange (SVPE) is an affordable and potentially effective alternative form of plasma exchange. SVPE is the repeated removal of small volumes of supernatant plasma over several days via sedimentation of patient whole blood.
