Patient with a history of severe Guillain-Barre syndrome in August of 2011 following vaccination with the diphtheria, tetanus, and pertussis vaccine. Approximately 3 weeks prior to the onset of his symptoms, had 8 teeth that were extracted.  Treated with antibiotic prophylaxis and reportedly did well.  Approximately 2 weeks prior to the onset of symptoms, received DTaP vaccination, and 1 day prior to admission, complained of some upper respiratory congestion.  Was given Singulair.  The day prior to admission, started getting progressively weaker.  By the next morning, could no longer walk.  Taken to the Urgent Care and transferred to the Emergency Room and eventually hospitalized.  By Monday evening, was diagnosed with severe Guillain-Barre syndrome and started on IVIG.  CSF study 3 days into the course of the illness was reported as a normal study.  EMG done on August 10, 2011, showed a severe demyelinating process with some axonal involvement.  MRI of the brain and spine was normal except for nerve root enhancement in the cauda equina.  Received a 5-day course of IVIG, however, developed severe autonomic instability, profound weakness, eventually developed aspiration pneumonia, and required clindamycin antibiotic treatment for the pneumonia.  Given the worsening clinical presentation, eventually underwent 5 courses of plasmapheresis.  With the plasmapheresis, made a gradual recovery.  Was transferred to Rehabilitation on August 29, 2011, and was eventually discharged home on September 9, 2011. Patient is now back part time in school.  Is tolerating it very well.  Is continuing Rehabilitation 3 days per week.  This is scheduled to last for 12 weeks.  Is struggling with gaining weight.  Has only gained 3 pounds since discharge from the hospital, although patient is assiduously following the recommendations of Nutrition prior to discharge and is getting approximately 2600 calories per day.

Fortunately made an essentially complete recovery.  Continuing to receive physical therapy and this is slated to last another 12 weeks.  Now back in school part time. Asks me what to do in terms of recommendations for future vaccinations.  I consulted the CDC, both calling them and going to their recommended web site.
