[CIS PIDD] [cis-pidd] Yellow Fever Vaccine in sIgAD

[Soheil Chegini]

Selective IgA deficiency is defined as an undetectable serum IgA level when serum IgG and IgM are normal. The detection level for most labs is now <7.8 mg/dL. She has slightly low IgA and IgM, but this does not qualify for selective IgA deficiency.

Dear all,


I would like to bring the "Yellow Fever vaccine and IgA deficiency" topic back to the group discussion. Last discussion concluded that YF vaccine is not contraindicated in IgA deficiency. 


I received an e-mail today from a colleague. His patient, a 25 yo woman with history of Grave's disease, is planning to visit Ghana and she needs Yellow Fever vaccination. She had slightly low IgA and IgM 3 years ago (checked during Grave's work-up). She does not have recurrent infections and she is otherwise healthy. She and her father contacted CDC and were told that YF vaccine is contraindicated in selective IgA deficiency and they were given this reference  http://www.cdc.gov/mmwr/pdf/rr/rr6002.pdf  (Table 13 on page 48). I was not aware of this publication, so I wanted to let you all know about it and ask your opinion. 

Back to the patient: Her recent IgA level is 49 mg/dl (70-312), IgM is 43 mg/dl (56-352) and IgG is 913 mg/dl (639-1349).  I am not impressed by these values. But the family is reluctant. What would you recommend for this patient? Does she have selective IgA deficiency? What about slightly low IgM? Do you think this combination should be a contraindication for the vaccine?  

Dewton, you mentioned that YF vaccine is widely used in inland Brazil. Do you have any data on the frequency of IgA deficiency in patients who developed severe reaction to this vaccine? 

Thank you,

Yesim
