Rheumatic presentations of Guillain-Barré syndrome as a diagnostic challenge: A case series.

BACKGROUND

Guillain-Barré syndrome (GBS) is an immune-mediated acute polyradiculoneuritis often in post-infectious context. It is a therapeutic emergency as early treatment may prevent disabilities. Pain in GBS has been described extensively, may precede neurological symptoms and bring the patient to rheumatology departments in the first place.

OBJECTIVE

To describe the clinical presentations and diagnosis of GBS cases referred to rheumatology departments.

METHOD

For this retrospective case-series, we screened patients of the rheumatology department (university hospitals of Strasbourg), whose hospitalization records were associated with the ICD-10 Code G61.0 (GBS) from 1993 to 2020. We included patients fulfilling the 1990 NINDS criteria and level one of the Brighton collaboration criteria. We measured the time from symptoms onset to admission and from admission to lumbar puncture as a marker of outpatient and inpatient diagnosis delay, respectively.

RESULTS

We describe 8 GBS cases. Six had nociceptive-like prodromal pain: back pain (n=3), peripheral arthralgia (n=1) or diffuse myalgia (n=3). The median time from symptoms onset to admission was 7days [range: 3-60] and the median time from admission to lumbar puncture was 2days [range: 0-8]. Two patients became severely tetraparetic, one requiring intubation. At last follow-up (median: 5.5years; range: 0.5-23years), 4 patients had recovered completely and 4 kept disabilities.

CONCLUSIONS

Rheumatic presentations of GBS are rare and diverse. Rheumatologists should be aware of this presentation because early diagnosis and treatment may prevent rapid motor worsening. Rapidly progressive symmetric weakness and areflexia appear as the best clinical diagnosis markers.
