Summary

Main objectives:

Evaluate the effectiveness of an administration of 3,4-diaminopyridine (FIRDAPSE ®) in severe botulinic poisoning in measuring the effect on electrophysiological and respiratory parameters

Secondary Objective:

Study the natural history of electrophysiological and respiratory parameters during the botulinic intoxication

Primary endpoint:

Clinical, electrophysiological and respiratory before and after administration of 3,4-diaminopyridine.

Study Design:

Pilot study, prospective, interventional.

Study population:

Case series (n = 8 patients) suffering from botulinic type A, respiratory failure, but with no other organ failure

Experimental treatment :

3,4-diaminopyridine, FIRDAPSE ® (BioMarin) The dosage will be gradually increased according to a predetermined scheme and will not exceed 60 mg / day and 20 mg / dose.

Statistics:

Intra-individual comparison of physiological parameters measured before and after administration of 3,4-diaminopyridine. Electromyographic and respiratory parameters will be measured for each patient. Then a dose of 10 mg of 3,4-diaminopyridine will be administrated. If this dose is well tolerated and provides a relative improvement of 10% for at least one of the parameters studied, the dose will be maintained at 10 mg for 48 hours 3 times a day then increased to 20 mg.

The primary endpoint is the change in the amplitude of muscle response evaluated by the subtraction of amplitude at T1.5 and T0.
