[PAGID] Lymphopenia and arthritis

...which has made things very interesting this morning. I was unaware of
this disorder until the path came back, but I have since learned that EV
is a form of defective host immunity to specific types of cutaneous but
not genital HPV infections, which leads to persistence and oncogenic
transformation (involving skin and in some cases solid tumors such as
lymphomas) in most patients. In the attached reference, Dr. Casanova
regards EV as a PID and suggests that it may have been the first PID ever
described, in the 40s. Most affected patients have null mutations in EVER1
or EVER2 which are transmembrane proteins expressed primarily in the ER of
keratinocytes and which function in zinc metabolism.

Various immunologic abnormalities have been described in EV patients over
the years including expansion of NK cells / LGL and CD4+ T cell
lymphopenia (both of which my patient has); and some publications have
made reference to gamma delta expansion. But I am unable to find any
mention of associated arthritis or autoimmunity. (molecular mimicry?)

So now my questions are: should we stop the methotrexate, in view of what
is known about the natural history of EV? Are this child's lymphocyte
abnormalities secondary to chronic cutaneous viral infections or does zinc
metabolism or EVER1/2 function play a role in lymphocyte homeostasis as
well? And does anyone have experience with these patients?

Scratching my head,
Brian

Revisiting human primary immunodeficiencies.

Abstract
Human primary immunodeficiencies (PIDs) are often thought to be confined
to a few rare, familial, monogenic, recessive traits impairing the
development or function of one or several leucocyte subsets and resulting
in multiple, recurrent, opportunistic and fatal infections in infancy. We
highlight here the rapidly growing number of exceptions to each of these
conventional qualifications. Indeed, bona fide PIDs include common and
sporadic illnesses and may present as dominant, or even polygenic traits;
their pathogenesis may involve non haematopoietic cells, and they may
result in single episode of illness, with a single or multiple morbid
phenotypes, some of which may involve infection, in otherwise healthy
adults. We need to increase awareness of the multitude of clinical
presentations of human PIDs considerably and rapidly in the medical
community. Human PIDs should be considered in a wide range of clinical
situations.

Thanks for your thoughts, Jason. His IgE is normal and he does not have
palpable nodes, liver, or spleen. We have not imaged his chest or abdomen,
and he has not had a slit lamp exam, which is a good idea. Because of the
poor response to Aldara, the dermatologists just biopsied his diffuse,
salmon-colored macular rash on Monday and indeed the path demonstrates
epidermodysplasia verruciformis consistent with HPV infection.

Dear Brian,

Interesting case. Lymphocytopenia, impaired cell-mediated immunity,
arthropathy (can look like JIA) and osteopenia can all be [variable]
features of sarcoidosis, which can occur at this age.

Not a perfect fit however (e.g. hx low PTH, growth failure, facies) but
sarcoidosis is pretty heterogeneous.

What about the following:

IgE?

Hepatosplenomegaly?

Intrathoracic (or other) lymphadenopathy?

Skin or eye changes?

Regards,

Jason
