Percentage of relapse or second episode in GBS

Percentage of relapse or second episode in GBS

What percent of patients with GBS suffer a relapse or second episode? 

Based on several series of Guillain Barre syndrome patients, the incidence of recurrence lies somewhere between 1% and 6%, and recurrences may occur months to years after the initial episode.

A recent study found that patients with Miller–Fisher syndrome, younger age, and milder disease were more likely to suffer a recurrence.

There also appeared to be a trend toward shorter intervals between subsequent episodes and a more severe deficit with each recurrence.

The risk of relapse or a second episode of Guillain-Barré syndrome (GBS) varies among individuals and depends on several factors.

The overall rate of relapse or second episodes of GBS is relatively low. Here are some key points to consider:

  1. Overall relapse rate: Research studies have reported varying rates of relapse or second episodes in GBS, ranging from around 1% to 6%. However, it’s important to note that these rates can vary depending on the specific study population and follow-up duration.
  2. Timeframe for relapse: Relapses or second episodes of GBS can occur at different time points after the initial episode. Some relapses may happen within weeks or months of the initial onset, while others may occur after several years.
  3. Risk factors: Certain factors may increase the likelihood of relapse or a second episode of GBS. These factors include younger age at initial onset, preceding infection with Campylobacter jejuni, certain antibody profiles (such as anti-GM1 antibodies), and specific GBS subtypes (such as Miller Fisher syndrome).
  4. Variability among subtypes: Different subtypes of GBS may have varying rates of relapse. For example, Miller Fisher syndrome, which is a variant of GBS, tends to have a lower relapse rate compared to other subtypes.
  5. Treatment and outcomes: Prompt and appropriate treatment of the initial episode of GBS with intravenous immunoglobulin (IVIG) or plasma exchange (plasmapheresis) can help improve outcomes and potentially reduce the risk of relapse. Ongoing management and follow-up with healthcare professionals are crucial for monitoring any signs of relapse or recurrence.

It’s important to consult with a healthcare professional, such as a neurologist or specialist in GBS, for personalized information and guidance regarding the risk of relapse in your specific case. They can provide a more accurate assessment based on your individual circumstances and medical history.
