The before introduced solid phase ELISA was employed for the RF determination in the sera of RA patients and controls. The threshold values for positive results (calculated as the 95% distribution percentile of healthy donors) were 8, 3, and 3 U/ml for IgA, IgG, and IgM-RF, respectively. The results confirm the validity of the assay with clear negative results in several negative control groups (healthy donors, patients of the oto-, rhino-, laryngeal ambulance, diabetes mellitus, degenerative arthropathies; n = 111, median IgA, IgG and IgM-RF values of less than or equal to 2, less than or equal to 2 and less than or equal to 1 U/ml, respectively; 25-75% distribution percentiles within the median value) and positive results in the positive control group (seropositive RA; n = 20, median IgA, IgG and IgM-RF values of 324, 479 and 170 U/ml, respectively). 16/24 patients with so-called seronegative RA (negative Latex Fixation Test or Waaler Rose Test) had positive results in the ELISA, two of them had rheumatoid nodules clinically. The IgG-RF activity in the ELISA appears to be a good parameter for the course control of RA under gold therapy. 10 RA patients with clinical improvement of disease (declining ESR, CRP, joint index) after six months of gold therapy (= 0.6 g total gold amount) had a decline of total RF activity of 70% in median, whereas 10 patients with no clear effect on disease activity had only a decline of 20% in median.

Variation of serum immunoglobulin (Ig) levels and increased frequency of selective IgA deficiency are frequently associated with autoimmune diseases. In insulin-dependent diabetes mellitus (I.D.D.M.) pathogenesis autoimmunity is known to play a causative role. Aim of the present study was to evaluate serum major immunoglobulin subclasses levels and frequency of IgA selective deficiency in juvenile onset I.D.D.M. IgG, IgA, IgM concentrations were determined in 191 insulin-dependent children and adolescents (100 males, 91 females; mean age 10.6 divided by 4.8 yrs; mean duration of I.D.D.M. 5.7 divided by 3.9 yrs) and in 180 age-matched healthy controls. Mean Ig levels were comparable among both group. Duration of I.D.D.M. did not affect mean serum Ig levels. Selective IgA deficiency was found in 7 on 191 diabetics: this gives a prevalence of the defect of 1:27, which is higher than in the Italian pediatric population (1:500). HLA typing evidenced 2 DR3 positive patients, 2 DR4, 1 B8-DR3 and 1 B8-DR3/DR4. The significance of selective IgA deficiency in I.D.D.M. is discussed.

In order to elucidate the possible relationship between insulin autoantibodies (IAA), conventional (ICA-IgG) and complement-fixing (CF-ICA) islet cell antibodies and Coxsackie-B4 and mumps virus-specific antibodies (IgG, IgM and IgA classes), we studied 194 children and adolescents with newly diagnosed Type 1 (insulin-dependent) diabetes. Sixty-one (31.4%) of the subjects were IAA-positive at diagnosis and 73.8% (45/61) of these also had ICA-IgG compared to 51.1% (68/113, p less than 0.01) of IAA-negative children. CF-ICA showed no significant association with IAA. The levels of IAA were significantly higher in the patients with ICA-IgG compared to those without [5.9 +/- 1.6% (SEM) vs 2.5 +/- 0.3%, p less than 0.01]. The patients positive for IAA were younger at diagnosis than the IAA-negative ones; (7.1 +/- 0.5 vs 9.3 +/- 0.3 years, p less than 0.001) and this was also true for ICA-IgG-positive children (8.1 +/- 0.4 vs 9.4 +/- 0.5 years, p less than 0.05) in comparison to ICA-IgG-negative subjects. No significant associations were found between IAA or ICA on the one hand and a positive family history of Type 1 diabetes or metabolic derangements at diagnosis on the other. Subjects negative for ICA were more frequently positive for mumps virus specific IgG antibodies than the ICA-positive patients (50/80 vs 53/111, p less than 0.05), and Coxsackie-B4 virus-specific IgA antibodies were more common in the CF-ICA-negative than the CF-ICA-positive children (53/111 vs 29/80, p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

A total of 203 patients with insulin-dependent diabetes mellitus (IDDM) were screened for coeliac disease (CD) by means of serum IgA and IgG antigliadin (AGA) (ELISA) and total anti reticulin antibody (ARA) IFL assay. As suggested by Savilhati, the combination of the IgA and IgG AGA test with IgA titration in serum (to find IgA deficient individuals) identifies almost 100% of CD patients. In this study ARA antibody assay was performed and two new suspect coeliac cases were found among IgA AGA negative children. Together the ARA and AGA tests give a 3% overall prevalence of CD in IDDM. The confirmation of CD must still be obtained with jejunal biopsy. Even high titres of AGA IgG are less specific for coeliac disease and in IDDM may identify those patients who are immunologically more hyperreactive.

We report the clinical features of 62 consecutive patients with lichen planus observed in 18 months. The largest number of cases occurred between 50 and 70 years of age. Thirty-four patients had lichen planus only. In the remainder, lichen planus was associated with chronic liver diseases (16 cases), immune-related disorders (7 cases), and diabetes (5 cases). Mucous-erosive lichen planus was significantly more frequent in cases with lichen planus and other diseases. In all patients with liver diseases the histological features always showed a severe liver involvement. No relationship was observed between lichen planus and the etiology of the liver diseases. Females were more affected by immune-related disorders than males. The above data, together with the increased levels found of IgA, auto-antibodies, and cryoglobulins, even in cases with lichen planus only, suggest that lichen planus results from an immune imbalance, often associated with systemic involvement.

We studied antibodies to cow's milk, beta-lactoglobulin and gliadin with enzyme-linked immunosorbent assay in the sera of 91 children with insulin dependent diabetes mellitus (IDDM); 36 of them were newly diagnosed. The children with newly diagnosed IDDM had significantly higher levels of IgA antibodies to cow's milk and to beta-lactoglobulin, and IgG antibodies to beta-lactoglobulin than 100 age-matched controls. We infer that either the pattern of cow's milk consumption is altered in children who will have IDDM, or their immunological reactivity to proteins in cow's milk is enhanced, or the permeability of their intestines to cow's milk protein is higher than normal.

Examination of 13 untreated patients with Itsenko--Cushing disease and syndrome showed an increase in total Ig as well as IgA, IgM and IgG, a decrease in the number of O-cells, and the absence of significant change in in the blood content of T-lymphocytes. A decrease in the amount of B-lymphocytes was noted in this group of patients with GTT of diabetic type or mild diabetes mellitus. Repeated examination of 7 of these patients 1-1.5 mos. after the resection of one adrenal gland showed that the content of O-cells had returned to normal, tension of the system of humoral immunity was on a decrease and combined with a decrease in the excretion of 17-OCS fractions though they were still above normal. Hyperlymphocytosis with a high level of T- and B-lymphocytes and the normal content of O-cells was noted in 11 patients after bilateral adrenalectomy for Itsenko--Cushing disease receiving maintenance doses of cortisone.

The combined occurrence of atopy and diabetes of type I in childhood is extremely rare; this is explained in the literature by the different genetic backgrounds. In the present work, a study was made whether juvenile diabetes can be accompanied by symptom-free atopy. In 67 insulin-dependent diabetic children, the total and the specific IgE, and the IgG, IgA and IgM levels were determined, and cutaneous prick test was performed. In 23 of the examined children, the total IgE level proved to be higher than the age-related normal mean + 2 SD; the prick test revealed various degrees of positivity in 30% of these same children, with a complete lack of atopic symptoms. The total IgE levels were found to be elevated not only in the first year of the disease, but also in the following 5-10 years. The results indicate the existence of symptom-free atopy in insulin-dependent diabetes; additionally, the possibility of a genetically determined disturbance of IgE synthesis is suggested. Data are provided on the autoimmune pathogenesis of insulin-dependent diabetes.

We analyzed the flow rate and composition of paraffin-stimulated whole saliva samples from 35 adult diabetic patients and their age- and sex-matched, non-diabetic, clinically healthy controls. All patients had insulin-dependent diabetes (IDDM) with a mean (+/- S.D.) duration of 14.0 +/- 9.1 years. The saliva analysis included the quantitation of total protein, amylase, immunoglobulins (isotypes A, G, and M), and the non-antibody, innate antimicrobial factors (lysozyme, lactoferrin, salivary peroxidase, myeloperoxidase, thiocyanate, and hypothiocyanite). The whole saliva samples from diabetic patients had significantly higher amounts of IgA (p less than 0.001) and IgG (p less than 0.05) than did the controls. No differences between the study groups were observed in flow rate, protein content, amylase activity, or IgM. The levels of innate defense factors were similar in both study groups except for salivary peroxidase, which was higher (p less than 0.02) among diabetics than among controls. Our results indicate that the antimicrobial defense capacity of whole saliva is not impaired in diabetic patients.

Five Persian Jews were detected with the polyglandular deficiency syndrome (PDS). Primary hypoparathyroidism and hypogonadism were present in each, adrenal insufficiency in two, and insulin-dependent diabetes mellitus and latent hypothyroidism in single subjects. The percentage of T and B cells, and the mononuclear cell response to phytohemagglutinin and Concanavalin A were normal in all five. IgG and IgA levels and the OKT4+/OKT8+ cell ratio were low in one subject. Antinuclear and antithyroid antibodies were present in one subject. HLA-DR5 was present in 4/4, HLA-24 and B5 (B51) in 3/4 subjects. A single case of isolated hypoparathyroidism (IHP) was detected among 12 first degree relatives. HLA antigens B8, DR3, were absent in all of these subjects. Seven non-Iranian Jews with IHP were also examined. HLA A26 or A25 were present in all seven. Persian Jews appear to have a unique variant of PDS.
