In this study serum IgE levels were measured by a double-antibody radioimmunoassay in 31 patients with serum IgA concentration less than 0.01 mg/ml who were followed in the arthritis and allergy clinics. On a group basis there was no significant difference in mean serum IgE levels between the IgA deficient patients and normal subjects of the same age. However, in the absence of atopic disease, IgA deficient patients had significantly lower serum IgE levels. When atopy was associated with
IgA deficiency
IgE levels were the same as in the normal subjects but significantly lower than those of atopic non-IgA deficient patients. IgE levels in those with recurrent respiratory tract infection were not different. Adults with anti-IgA antibodies had significantly lower IgE values. IgE levels in patients with RA, JRA or
SLE
were not significantly different. Selective IgA deficient patients may have a relative deficiency of serum IgE depending on the comparison group.

The families of two patients with
SLE
and
IgA deficiency
were examined. A study of the first patient's family revealed that
IgA deficiency
was determined by an incompletely penetrant autosomal dominant gene not linked to the HLA locus. Antinuclear antibodies, found in consanguineous and nonconsanguineous relatives were not related to the presence of
IgA deficiency
or any HLA haplotype. The second patient and his father with antinuclear, anti RBC, and antithyroid auto-antibodies shared an HLA haplotype not present in other sibs.
IgA deficiency
was not inherited in this family but may have influenced the expression of disease in the propositus or could have resulted from the disease itself.

The prevalence of antibodies to immunoglobulin A (IgA) was studied in eighty-three subjects with selective
IgA deficiency
(SIgAD), thirty-three normal individuals, thirty-two children with juvenile rheumatoid arthritis (JRA) and normal or elevated IgA, seventeen children with
systemic lupus erythematosus
(
SLE
) and normal or elevated IgA, and thirteen patients with hypogammaglobulinaemia. Anti-IgA antibodies were detected by haemagglutination of human erythrocytes coated with one of two IgA myelomas by the chromic chloride technique. Antibodies to IgA were not found in significant titre in individuals with normal or elevated IgA or in those with hypogammaglobulinaemia. In IgA deficient patients, elevated titres were found in 25--30% of those who were healthy or who had non-rheumatic diseases, 50% of those with rheumatoid arthritis, 77% of those with JRA and 100% of those with
SLE
. Patients with rheumatic diseases and SIgAD may therefore be particularly at risk of developing anti-IgA-mediated reactions to blood products.

Sera of children with juvenile rheumatoid arthritis and other connective tissue diseases were tested for antibodies to native DNA by a radiolabeled-binding assay. Normal values were obtained in 130 children with JRA, including 28 with uveitis and 14 with selective
IgA deficiency
. Normal values were also found in sera from children with dermatomyositis, scleroderma, polyarteritis, ankylosing spondylitis, and a variety of other nonconnective tissue diseases. The only sera with elevated DNA-binding assays were from children with
systemic lupus erythematosus
. On the basis of these data, increased levels of antibodies to native DNA distinguished patients with active
SLE
from children with JRA.

The presence of antibodies to native DNA, single-stranded DNA, and double-stranded RNA was determined for 37 patients with selective
IgA deficiency
, 11 patients with Wiskott-Aldrich syndrome, seven patients with common variable agammaglobulinemia, 14 patients with ataxia telangiectasia, six patients with intestinal lymphangiectasia, and one patient with Nezelof syndrome. Of 37 patients with selective
IgA deficiency
, 11 had antibodies to at least one nucleic acid; six had antibodies to native DNA, seven had antibodies to single-stranded DNA, and four had antibodies to double-stranded RNA. The only other congenital immune deficiency disease studied in which antibodies to nucleic acids were found was the Wiskott-Aldrich syndrome; in this group three of 11 patients had antibodies to native DNA. Retrospective analysis of our patients with
SLE
disclosed a 2.6% prevalence of
IgA deficiency
, a prevalence clearly higher than in the general population. These studies provide further evidence of the association between autoimmunity and abnormalities of IgA production and suggest a relationship between thymic-derived immune regulation and IgA production.

A significant increase in the prevalence of selective
IgA deficiency
has been observed in patients with autoimmune disorders such as
systemic lupus erythematosus
and rheumatoid arthritis. Insulin-dependent diabetes mellitus (IDDM) is an autoimmune disease and susceptibility to both IDDM and
IgA deficiency
is associated with HLA DQB1 alleles encoding non-Asp amino acids at position 57. In order to assess whether the prevalence of selective
IgA deficiency
is increased in IDDM, we have screened a homogeneous series of adult patients with IDDM for selective
IgA deficiency
. One patient (1:261) was found to have a selective
IgA deficiency
. The prevalence of selective
IgA deficiency
among adult French blood donors is 1:1400. Thus, although IDDM and selective
IgA deficiency
are both associated with the presence of non-Asp amino acids at position 57 of the HLA DQ beta chain, the frequency of this immunodeficiency in adult IDDM patients is not significantly increased.

Overlapping syndrome (OS) is usually used as the term of the combinations of three connective tissue diseases, i.e.,
systemic lupus erythematosus
(
SLE
), progressive systemic sclerosis (PSS) and polymyositis (PM) or dermatomyositis (DM). OS is sometimes confused with mixed connective tissue disease (MCTD) since the definitions of the both diseases have not been established yet. Rheumatoid arthritis (RA) is a distinct disease and only exceptionally associated with the other CTD. These rare cases include destructive arthritis of
SLE
and PSS, multiple peripheral type of psoriatic arthritis, and arthritis associated with X-linked hypogammaglobulinemia and selective
IgA deficiency
. The conditions complicated with RA are not uncommon. They are osteoporosis, Sjogren's syndrome, amyloidosis and so on. There are some rare conditions or diseases which will be able to develop to RA. These peculiar cases include juvenile rheumatoid arthritis, adult onset Still's disease, polymyalgia rheumatica and palindromic rheumatism.

Serological studies conducted on sera from a group of 31 male
SLE
patients revealed a 32% prevalence of 7S IgM and a 9.7% prevalence of
IgA deficiency
. Previous reports using similar methods indicated a higher (43-50%) prevalence of 7S IgM than was found in studies involving predominantly females with
SLE
(15-18%), and an overall prevalence of
IgA deficiency
ranging from 0.95% to 4.6%. Males resembled females in the prevalence of Fc-receptor specific reticuloendothelial system dysfunction, correlating with levels of circulating immune complex-like material and disease activity.

A 22 year-old-female had suffered from polyarthralgia and Raynaud's phenomenon since 1984. In 1986, she was diagnosed as
systemic lupus erythematosus
(
SLE
). In April 1988, she was admitted to Kawasaki Municipal Hospital because of fever and dyspnea on exertion (DOE). Physical examination showed high fever, butterfly rash, oral ulcer and elevation of heart sound IIp on auscultation. Laboratory findings revealed that erythrocyte sedimentation rate was elevated to 105 mm/hr. The following values were observed, anti DNA antibody 391 IU/ml, serum IgA 5mg/dl, anti IgA antibody weakly positive. Chest X ray showed CTR 65%. Echo cardiogram showed massive pericardial effusion. 201T1 myocardial SPECT revealed right ventricular pressure over loading. PSL 40 mg/day was started to administer for the massive pericardial effusion due to
SLE
activities. On 6th of June, right heart catheterization confirmed the pulmonary hypertension (PPA 22 mmHg, Pulmonary artery resistance (PAR) 1163 dyne/sec/cm-5/mm2). By the treatment with PSL, massive pericardial effusion was gradually improved but DOE clinically unchanged. Second right heart catheterization was done on 8th of August. PAR was improved to 895 dyne/sec/cm-5/mm2 but PPA was elevated to 26 mmHg. It is very interesting that PPA was elevated although PAR was improved by PSL therapy. It is considered that the increase in venous return which was caused by improvement of massive pericardial effusion induced conversely the elevation of PPA. Additionally she was complicated with
IgA deficiency
. It may occur not only by the immunogenetical disorder such as HLA or IgG subclass alteration but also by anti IgA antibody or lymphocytes dysfunction complicated with
SLE
.

Polyclonal B cell activation (PBA) and autoimmune disease can be induced in immunologically normal mice, or enhanced in
lupus
-prone mice, by bacterial lipopolysaccharide (LPS). Because immune defects are common in autoimmune diseases and
IgA deficiency
is prevalent in patients with
systemic lupus erythematosus
, we investigated: (i) whether LPS might induce
IgA deficiency
in normal mice; (ii) whether
IgA deficiency
might be a feature in
lupus
-prone mice; (iii) whether, if present in
lupus
-prone mice,
IgA deficiency
could be further accentuated by LPS; and (iv) whether the effects of LPS on IgA concentrations of normal and
lupus
-prone mice might be reversible upon withdrawal of LPS. We injected normal (C57BL/6) and
lupus
-prone (NZB/W) mice with 50 micrograms of LPS from Salmonella minnesota Re595 twice a week for 5 weeks and then discontinued LPS for 6 weeks. We determined the concentrations of plasma immunoglobulins, DNA antibodies, and circulating immune complexes before, during, and after mice were exposed to LPS. Our results indicate that: (i) LPS induces
IgA deficiency
in normal mice concurrently with PBA; (ii)
IgA deficiency
is a feature of
lupus
-prone mice; (iii) LPS accentuates naturally occurring PBA and
IgA deficiency
in
lupus
-prone mice; and (iv) LPS induced, or LPS enhanced,
IgA deficiency
and PBA in normal and
lupus
-prone mice persist long after withdrawal of LPS. Thus, LPS triggers or enhances autoimmune disease by a mechanism that involves in part PBA with selective increase (IgG, IgM) and concurrent decrease (IgA) of specific isotypes.
