[CIS PIDD] [cis-pidd] Sub-protective pneumococcal titers in a CVID patient on therapeutic doses of IgSQ and recurrent bronchitis

[Keller, Michael]

Hi Soheil,

Increasing his hizentra dose sounds like a very good move as we often (albeit in pediatric patients) see much higher levels achieved with subQ.

You mention no bronchiectasis - has he had a recent chest CT or MRI to ensure that there is no developing interstitial disease?

Best regards,
Mike

Subject: [cis-pidd] Sub-protective pneumococcal titers in a CVID patient on therapeutic doses of IgSQ and recurrent bronchitis

Dear all,

I am wondering what others would suggest to reduce the frequency of bronchitis in a 54 y.o. man with CVID who is on Hizentra 10 g SQ weekly and has an excellent IgG level (814 in 6/14 and 916 1/15). He has responded well to oral antibiotics (Ceftin and Augmentin x 10 each) for 2 episodes of bronchitis that he has had this fall with resolution of his symptoms. He is also treated for asthma with Symbicort 160/4.5 and his spirometry is stable at his baseline with some irreversible airflow obstruction. No bronchiectasis.

Here are his 14-serotype pneumococcal titers:
Type 1                   0.9
Type 3                   0.9
Type 4                   <0.3
Type 5                   1.4
Type 8                   1.0
Type 9                   0.7
Type 12                 0.4
Type 14                 3.3
Type 19                 1.4
Type 23                 0.9
Type 26                 1.1
Type 51                 1.3
Type 56                 1.2
Type 68                 0.7

These titers suggest adequate protection only against 4 of the 14 tested serotypes, but I am not inclined to increase his dose of Hizentra given his excellent total IgG. He does not produce any Ig (IgA,7 and IgM 11), and his pre-Treatment IgG was 151. He is tolerating the infusions well and I have no other excuse to change the Ig preparation.

I would very much appreciate your help and advice. Thank you very much in advance.

Best regards,
sc
