The prevalence of coeliac disease (CD) was investigated in an epidemiological study of school children from a district of Rome. Mass screening of IgA-AGA levels (anti-gliadin antibody) were determined in blood samples from the study group and the results were positive in 19 children. Eighteen of these agreed to undergo endoscopic biopsy. Histological study of the duodenal specimens revealed villous atrophy in twelve children none of whom had the characteristic symptoms of CD. The most frequent complaints were abdominal pain, aphtous stomatitis, and atopic dermatitis. The high prevalence of CD in this study suggests the necessity for the widest range of epidemiological research.

We investigated the immunoregulatory properties of a recently described inhibitor of lymphocyte proliferation, suppressin (SPN). It was determined that preincubation of murine leukocytes with SPN enhances natural killer cell (NK) activity. In addition, SPN potentiates interferon-gamma (IFN-gamma) augmentation of NK activity. Furthermore, preincubation of murine leukocytes with SPN induces the production of IFN-alpha/beta. The IFN-alpha/beta produced is active in NK assays as well as vesicular stomatitis virus neutralization assays. In vivo, SPN increases the time of survival of C57BL/6 mice injected with EL-4 lymphoma cells. Interestingly, SPN inhibits immunoglobulin (IgA, IgG, and IgM) production in response to the mitogen, concanavalin A in a dose-dependent manner. Collectively, the above data indicate SPN may have numerous applications in clinical science including tumor surveillance and autoimmune diseases such as arthritis.

Bloom's syndrome (BS) is an autosomal recessive disease characterized by short stature, sensitivity to sunlight, and telangiectasic malar erythema. It is associated to chromosomal breakage, to primary combined immunodeficiency, and to a high incidence of neoplasias. The authors report the case of two siblings with BS and associated immunodeficiency. Both patients were male and 5 (A) and 4 (B) years old at the time of diagnosis. Chronic diarrhea, recurrent otitis media, purulent rhinitis, conjunctivitis and pyodermatitis were reported by patient A. Patient B was admitted with diagnosis of bilateral neuroblastoma and had the tumor resected. Later on, he presented with oral moniliasis, herpetic stomatitis, and skin abscesses. This patient did not have recurrent infections. Immunological evaluation showed normal serum levels of CH50, C3, and C4 for both patients. Serum IgG, IgA, IgM, and salivary IgA levels were: 455 mg/dl, 15mg/dl, 20mg/dl, 0.6mg/dl for A, and 400mg/dl, 15mg/dl, 20mg/dl, and 0.2mg/dl for B, respectively. Serum antipolio antibodies (1, 2, and 3) were normal, and low levels of isohemagglutinins were observed in both patients. T cells subset determination showed: patient A--OKT3 = 66%, OKT4 = 33%, OKT8 = 32%, and 4/8 ratio = 1.0; patient B--OKT3 = 70%, OKT4 = 32%, OKT8 = 34%, and 4/8 ratio = 1.0. In vitro cellular immune response to PHA was depressed only in patient B. Patients karyotype showed chromosomal breaks with sister chromatid exchanges. Neither patient had abnormal alphafetoprotein and carcinoembryonic antigen serum levels. The rarity of such associations justifies the presentation of the cases.

To evaluate the immune response in an immunosuppressed population, antibodies against commercially available Candida albicans antigens were prospectively studied during 37 episodes of acute stomatitis caused by C. albicans and 36 episodes complicated by deep-seated mycoses in 62 adult patients with hematologic malignancies. During uncomplicated stomatitis in patients with acute leukemia, the mean peak IgM, IgG and IgA class enzyme-linked immunosorbent assay (ELISA) units differed significantly from the basic level preceding fungal infection. Mean time until peak values was 2.7-3.8 weeks after diagnosis of stomatitis. During systemic mycoses the antibody response was similar. Among patients with other hematologic malignancies, predominantly lymphomas, several were terminally ill and responded infrequently by antibody production. Similar results were given by Ouchterlony immunodiffusion and counterimmunoelectrophoresis. Thus, patients with acute leukemia showed an antibody response to fungal infection; the peak values, however, were somewhat delayed.

The clinical and pathological study was performed in order to determine the histopathological and cytoimmunological characteristics of denture stomatitis. All specimens were biopsy materials from seventeen patients with denture stomatitis. Normal palatal mucosae from ten patients served as the control. In addition to the usual staining methods, naphtol AS-D chloroacetate esterase stain and peroxidase-antiperoxidase method were used to detect mast cells and plasma cells. Denture stomatitis could be divided into atrophic and hyperplastic types. The former showed a smooth and atrophic mucosa. The latter showed a large number of exophytic projections which were composed of marked acanthosis and submucosal fibrosis, and was further subdivided into granular and papillary subtype according to the size of projections. In the present study, there were six cases of the atrophic type, and eleven cases of the hyperplastic type (consisting of seven granular and four papillary subtypes). The hyperplastic type was more frequently observed in patients with partial dentures compared with complete dentures and was associated frequently with ill fitting of the denture base as well as agglutination of denture plaque. Cytoimmunological study revealed that there was a pronounced increase of plasma cells, especially IgG- and IgA-producing cells, and a moderate increase of lymphocytes as well as mast cells in both types of denture stomatitis. Mast cells were always noted in the area with marked plasma cell infiltration, suggesting an intimate relation between both cells. These findings suggest that the immunological reactions play some role in the pathogenesis of denture stomatitis.

Cryostat sections from 14 surgical specimens were examined to determine whether selected factors of the immune response related to histopathological reactions are present in the palatal mucosa affected by hyperplastic denture stomatitis. By means of various immunological techniques the presence of IgG, IgA, IgM, complement factor C3c, receptors for the Fc region of IgG (FcR) and for complement factor C3b (C3bR), T lymphocytes, and macrophages were studied. The inflammatory infiltrate was mainly located in the papillary part of the lamina propria. IgG, IgA, and IgM appeared both in plasma cells and intercellularly. FcR, C3bR, and T lymphocytes were present in the areas with inflammatory cell infiltrate. Macrophages were found in the papillary part of the lamina propria and within the epithelium. The immunological response in the mucosa affected by denture stomatitis was in many respects similar to that of marginal and apical periodontitis. We conclude that hyperplastic denture stomatitis is a complex inflammatory lesion showing elements of both humoral and cellular immune responses.

Thirty-three patients with alcoholic cirrhosis (AC), selected on widely recognized criteria (16, 57), were investigated prospectively for cutaneous manifestations of zinc deficiency. The patients were divided into 3 groups: group A (n = 12): AC without skin lesions; group B (n = 12): AC with skin lesions responsive to a zinc-free topical treatment or resistant to enteral zinc sulfate intake; group C (n = 9): AC with skin lesions cured by oral zinc replacement therapy alone. The lesions observed in group C were studied microscopically. Data concerning zinc metabolism (Zn concentrations in plasma, red cells, urine and hair; alkaline phosphatase values), biochemical criteria of AC (plasma serum-albumin concentration, IgA/transferrin ratio) and a malabsorption test (xylosemia 120 min after oral absorption of D-xylose 25 g) were compared by the variance analysis method. A control group (D, n = 12) was used as reference. Few cases of cutaneous manifestations of zinc deficiency in AC patients have been published. In more than one half of the 15 or so we found in the literature, an aggravating factor (total parenteral nutrition, digestive tract surgery) had to be taken into account. In this prospective study 9 new cases in which AC was the only cause of zinc deficiency are reported. A clinical picture similar to acrodermatitis enteropathica with peribuccal bullous lesions was observed in only one patient. In all other cases the patients presented with a cracked and reticulated eczema on the extensor aspect of the limbs and (often erosive) in the perianal and genital regions. The eczema was associated with cheilitis, glossitis, stomatitis, alopecia and, seldom, ungual Beau's lines. Disorders of behaviour, diarrhoea and bouts of lever regressing under zinc replacement therapy were frequent. Histology was not very specific, except for the presence of necrotic areas in the stratum germinativum, sometimes associated with small subcorneal pustules containing altered polymorphonuclears. In every case, it was the rapid regression of symptoms under zinc sulfate treatment that confirmed the diagnosis. Plasma zinc concentrations were most significantly decreased in all AC groups as compared to controls (61.2 +/- 19.4 vs 97.8 +/- 10.4 micrograms/100 ml) and also in AC patients with skin manifestations of zinc deficiency as compared to the other AC patients (44.4 +/- 9.2 vs 66.5 +/- 18.8 micrograms/100 ml) table V). Changes in serum-albumin levels and in hepatocellular function were parallel to changes in plasma zinc concentrations.(ABSTRACT TRUNCATED AT 400 WORDS)

The interferon (IFN) assay of the sera from the 40 patients with head and neck cancer was performed by the plaque-reduction assay with vesicular stomatitis virus in FL cells derived from human amniotic membrane. The patients mainly had Stage III or IV lesion without distant metastasis, and previously had not received any cancer therapy. All of the patients were histologically diagnosed as squamous cell carcinoma. When the serum IFN activity was characterized by acid treatment, significant increases of IFN-alpha/beta/gamma (n = 24, P less than 0.05) and acid-labile IFN (n = 24, P less than 0.001), and significant decrease of acid-stable IFN (n = 24, P less than 0.001) in the cancer patients of 50-to-79-year age group were found, as compared with those in the normal controls of the same age group (n = 20). When IFN titers including various immunologic parameters of the patients and normal controls were simultaneously assayed prior to the beginning of the cancer therapy, the titers of IFN-alpha/beta/gamma, acid-stable IFN, and acid-labile IFN were significantly correlated with some immunologic parameters such as natural killer (NK) activity, the absolute number of T gamma lymphocytes, the percentages of beta- and gamma-globulin, and the amounts of IgA, IgG, IgM, and beta 2 microglobulin. To define further the nature of this IFN, both sera of the patients and normal donors of 50-to-79-year age group were characterized by a neutralization assay with an antiserum to HuIFN-alpha and HUIFN-beta. The IFN activity left when the testing sera were neutralization with these antisera was expressed as gamma-like IFN. The titers of gamma-like IFN in the sera of patients (n = 24, P less than 0.0001) showed a highly significant increase as compared with the normal controls (n = 20). When the correlation between prognosis of the disease and titers of serum IFN were investigated by measuring gamma-like IFN and acid-stable IFN in the sera of patients, all of nine patients with good prognosis after the cancer treatment showed significant decreased levels of gamma-like IFN (P less than 0.01) and acid-stable IFN (P less than 0.05) as compared with those on the time before cancer therapy. On the other hand, titers of gamma-like IFN in the sera of six patients with recurrent disease showed a significant increase as compared with those on the IFN measurement before cancer therapy (P less than 0.05).(ABSTRACT TRUNCATED AT 400 WORDS)

A variant line (LV-1) of mouse myeloma MOPC 315 (IgA, lambda 2) has lost the ability to synthesize L chain. It synthesizes an altered H chain (H' chain) that is turned over intracellularly and is not secreted. Rescue of H' chain secretion can be accomplished by fusion of LV-1 to a variant of another myeloma line, MPC 11 (IgG2b, kappa), which only synthesizes a light chain. The hybrid (X-2) secretes the H' chain in a four chain structure (kappa 2 alpha' 2). In wild-type MOPC 315 cells, it was reported previously that inhibition of core sugar addition blocks the secretion of the H chain polypeptide. We have studied glycosylation in MPOC 315 wild-type, LV-1 variant, and X-2 hybrid cell lines. The ability of all three lines to add the core sugars mannose and glucosamine to heavy chain was demonstrated. Due to the instability of the H' chain in LV-1, it is difficult to assess H' chain fucosylation directly. To study fucose addition in LV-1, the enveloped virus vesicular stomatitis (VSV), which can infect the three lines, was utilized. The fucosylation and secretion of VSV glycoprotein G was discernible in all three lines; however, only LV-1 cannot activate free fucose, and instead fucosylates through conversion of the mannose intermediate. Normal fucose addition to H chain in a wild-type cell occurred immediately before secretion. The fact that degradation of H' chain in LV-1 begins before fucosylation suggests that the rescue of H' chain secretion by formation of the X-2 hybrid is due to the acquired presence of a suitable L chain rather than complementation of a sugar defect. These observations indicate that proper assembly of the polypeptide components of some secretory proteins, e.g., Ig molecules, is required for the secretion of the individual chains.

Whole saliva samples and lip biopsies were collected from 12 allogeneic bone marrow transplant recipients who developed extensive chronic graft-versus-host disease (GVHD) and from 10 healthy allogeneic and syngeneic recipients without GVHD. Six of ten biopsies from patients with chronic GVHD had lichenoid stomatitis or sialadenitis, or both, with sialodochitis. Seven of nine biopsies from patients free of chronic GVHD were entirely normal, and two had either mild glandular or mucosal changes. Salivary gland involvement in chronic GVHD was associated with decreased or absent levels of salivary IgA and inorganic phosphate, decreased salivary flow rates, and increased concentrations of salivary sodium, albumin, and IgG. The most striking abnormalities were found in patients with histologic evidence of sialadenitis. In contrast, marrow transplant recipients without chronic GVHD had normal salivary immunoglobulin and electrolyte levels. Secretory IgA deficiency may contribute to the frequent sinobronchial infections observed in patients with chronic GVHD.
