[CIS PIDD] [cis-pidd] Possible CVID case

[Richard Wasserman]

The patient is below the lower limit of normal for all three major isotypes
which would meet the classic definition of CVID. You don't say if the
pneumococcal titers showed an increase post vaccination. The patient may
have partially or fully intact memory but not be responsive to a
neoantigen. It is very likely that IgG therapy would be beneficial.
