Guillain-Barré syndrome, tuberculosis and inflammatory bowel disease: a multiple association.

Guillain-Barré syndrome (GBS) has been associated with both infective or non-infective aetiologies. GBS is usually preceded by acute respiratory or gastrointestinal infection but its association with tuberculosis has been exceptionally reported. Inflammatory bowel disease (IBD) is associated with clinical manifestations involving the neurological system, peripheral neuropathy is known to be related to IBD and, either demyelinating or axonal involvement of peripheral nerves have been described. We report an unusual case of GBS associated with lymph node tuberculosis and ulcerative colitis.

Cryoglobulinaemic neuropathy: a further cause of bilateral sciatic neuropathy.

Bilateral sciatic neuropathy is a rare condition and it has been described as a compression or entrapment neuropathy but it is an uncommon clinical manifestation due to necrotizing vasculitis. We report an unusual case of cryoglobulinaemic neuropathy in an elderly woman with no underlying infectious or neoplastic cause; acute bilateral sciatic mononeuropathy was the presenting clinical manifestation of the cryoglobulinaemia.

Antithrombotic therapy in elderly patients with atrial fibrillation: effects and bleeding complications: a stratified analysis of the NASPEAF randomized trial.

AIMS: Atrial fibrillation patients with prior embolism have a high risk of vascular events in spite of anticoagulant therapy and elderly patients carry an additional risk. We analysed and compared vascular events-rate between older and younger than 75 years atrial fibrillation patients randomized to anticoagulant-alone or combined antiplatelet plus moderate-level anticoagulant therapy. METHODS AND RESULTS: A total of 967 patients stratified by age and the history of prior embolism were randomized to therapeutic doses of anticoagulant-alone or combined antithrombotic therapy. Primary events were fatal and non-fatal ischaemic or haemorrhagic stroke/transient ischaemic attack, systemic embolism and myocardial infarction, sudden death and death from bleeding. The elderly, compared with the younger patients, had higher event-rate [hazard ratio 2.31 (95% confidence interval 1.37-3.90), P < 0.003]. The elderly suffered higher severe bleeding event-rate during anticoagulant therapy. The combined, compared with the anticoagulant therapy, reduced the vascular events-rate in the elderly (P = 0.012) and caused less intracranial haemorrhages and less bleeding mortality, although more non-fatal gastric bleeding. CONCLUSION: The elderly with AF had a higher event-rate than the younger patients. A higher severe bleeding event-rate was also registered in elderly patients receiving anticoagulant therapy. Combined, compared with anticoagulant therapy, significantly reduced vascular events and bleeding mortality in elderly patients.
