We describe here a case of Scleredema of Buschke in a female patient aged 63 with
IgA deficiency
. The disorder appeared after an acute episode of
tonsillitis
, followed by non-pitting, woody hardness of the skin of the face, neck, shoulders and upper part of the trunk. The disorder resolved after 5 months of penicillin treatment.

Nasal biopsy specimens from 15 adult patients with selective
IgA deficiency
but normal IgG-subclass levels were examined by immunohistochemistry for the presence of immunocytes producing various Ig isotypes. The mucosal samples were completely IgA-deficient except in two cases where 0.9% and 8.4% IgA cells were found, respectively (normal, 69.8%). Numerous IgG- (mainly IgG1-) producing cells were present in 10 samples; in five of these there were additional IgM- but virtually no IgD-producing cells, whereas in the other five a marked dominance of the IgD over the IgM isotype was seen. The latter category of patients had more upper airways infections (recurrent acute rhinosinusitis, otitis media, and
tonsillitis
) than the former, who had no recurrent upper respiratory tract infections except one patient with recurrent acute rhinosinusitis. The five remaining samples, which contained very few Ig-producing cells, were derived from patients with even more frequent infections than those showing IgD predominance. Our results indicate that IgM acts as a compensatory secretory Ig in the upper respiratory tract of some IgA-deficient subjects. However, immunoregulatory events favouring local IgD responses apparently do not support mucosal defence satisfactorily, either because local production of IgM is hampered or because IgD (which is not a secretory Ig) blocks complement-dependent reactions mediated by IgG and IgM antibodies within the mucosa.

FIRST REPORT: male child with repeated pulmonary infections from the age of 4 months. He was diagnosed as
IgA deficiency
(undetectable IgA levels) at the age of 3 years, when he presented repeated bouts of pneumonia and
tonsillitis
. Several immunologic evaluations were made between the ages of 4 months and 8 years. At 8 years and 9 months, the diagnosis of
IgA deficiency
was confirmed, and associated IgG2 and IgG4 deficiency (29.0 mg/dl y 0.01 mg/dl) with normal total IgG serum level was found. With the administration of intravenous gammaglobulin, the lung infections remitted and the subsequent clinical course has been uneventful up to now. SECOND REPORT: a boy with repeated infections since the age of 2 months.
IgA deficiency
was diagnosed at 1 year 7 months (undetectable serum IgA levels). At age 51/2 years, his clinical course worsened and more serious infections appeared. A new immunologic study revealed
IgA deficiency
associated with CD4 cell deficiency (432 cells/mm3) and normal CD3, CD19, and CD8 levels. Despite intensive antibiotic treatment and care, the child died. The findings suggest an association of
IgA deficiency
and common variable immunodeficiency.
