Abstract
In this report we evaluated CD4(+) T, CD8(+) T and natural killer (NK) cell counts, the levels of naive/memory subsets within the CD4(+) T lymphocyte population, expression of CD38 on T lymphocytes, and CD4(+) and CD8(+) T cell cytokine production in two girls with hyper-IgM (HIM) syndrome. Both girls developed recurrent infections early in infancy, presenting a wide spectrum of clinical manifestations, with a strikingly different disease severity between them. CD4(+) T cell counts were low in both children (patient 1: 214 cells/mm(3) and patient 2: 392 cells/mm(3)), and the CD4/CD8 T cell ratio was 0.4 for patient 1, the patient with the more severe disease, and 1.4 for patient 2. NK cell numbers were low in patient 1 (60 cells/mm(3)) and borderline (286 cells/mm(3)) with regard to normal levels in patient 2. An imbalance of naive and memory/effector cell subsets was found in both girls, with the percentage of CD45RA(+) 27(+) (naive) CD4(+) T lymphocytes being 5.8 and 12.4 for patients 1 and 2, respectively. Expression of CD38 on the surface of T lymphocytes was low in patient 1. Detection of intracellular interferon (IFN)-gamma and tumour necrosis factor (TNF)-alpha in CD4(+) and CD8(+) T lymphocytes upon PMA-Io stimulus was preserved in both children. In conclusion, we found low numbers of CD4(+) T lymphocytes and a dramatic redistribution of naive and memory/effector CD4(+) T lymphocytes in two girls with non-X-linked HIM syndrome. Furthermore, we found low expression of CD38 on T lymphocytes and low numbers of NK cells in the patient with the more severe disease, indicating a possible role for these cells in the pathogenesis of this immunodeficiency.

Abstract
A young boy was admitted to hospital for acute stroke. Cerebral angiography showed a pattern suggestive of vasculitis and a recent Mycoplasma pneumoniae infection was detected. The absence of microorganisms in cerebrospinal fluid, the pattern of vasculitis and previous reports supporting a post-infectious immunological mechanism for certain complications of M. pneumoniae infection suggest this mechanism as the cause of the stroke.

Abstract
A 33-y-old man with Hyper-IgM syndrome developed a severe tuberculous disease complicated by pleuritis and spondylitis. An abnormally decreased CD4/CD8 ratio, decreased CD4 + T-cell count and depressed natural killer cell activity implicated a coexistent cell-mediated immunodeficiency. To our knowledge, this is the first detailed report of tuberculosis associated with Hyper-IgM syndrome.

Abstract
BACKGROUND The autologous mixed lymphocyte reaction (AMLR) is an important immunoregulatory phenomenon in human immune disorders. The authors have determined the phenotype and assessed the response of malignant lymph node T-cells, from histologically and immunologically proven cases of peripheral T-cell lymphoma, in AMLR and allogeneic mixed lymphocyte reaction (MLR) and studied the secretion of lymphokines. METHODS The proliferative response, tritiated 3H-thymidine incorporation assay, was used to determine the AMLR and allogeneic MLR of the responding T-cells. An interleukin-2 (IL-2)-dependent T-cell line (CTLL) was used for the production of IL-2 by phytohemagglutinin-stimulated T-cells in a cytotoxic assay. B-cell growth and differentiation factor activity of T-cells was studied by enzyme-linked immunosorbent assay. RESULTS The AMLR of malignant lymph node T-cells was increased characteristically in 12 of the 14 lymphoma cases studied; however, that of the blood T-cells was decreased. The allogeneic MLR of the malignant lymph node T-cells and blood-purified T-cells of the eight cases investigated was decreased. Expression or deficiency of CD2 and CD3 antigens on malignant T-cells did not show any difference in the AMLR assay. CONCLUSIONS This study demonstrates an important tendency of malignant T-cells from patients with peripheral T-cell lymphoma to proliferate in AMLR. The highly augmented AMLR but deficient allogeneic MLR observed in these malignant T-cells indicate that autologous recognitive events may play an important role in the immunopathogenesis of this human disease.

Abstract
Immunoglobulin deficiency with increased IgM (hyper-IgM recurrent infection syndrome) is thought to be due to a defect of IgM/IgG isotype switching in B cells. Considerable genetic heterogeneity (X-linked, autosomal dominant or autosomal recessive inheritance, acquired forms) exists. We describe a case of hyper-IgM syndrome associated with massive lymphadenopathy in a 10-year-old girl with normal B-cell function. Absolute and relative increases of T-suppressor cells (CD8+) and a decrease of circulating CD4+ ("helper") cells were observed. The CD4+ cells present were all of the CD45R+ subtype, representing relatively immature ("naive") helper cells. In contrast, the number of CD4+ cells within the lymph nodes was increased. When tested fractionally, the patient's CD8+ cells selectively inhibited synthesis of IgG and IgA by normal B cells, but spared IgM. Normal allogenic T cells could induce IgG and IgA production by the patient's B cells. These findings suggest (a) a state of selective suppression of IgG and IgA synthesis with exclusive production of IgM, and (b) an abnormal recirculation of immature T-helper cells. This case represents a variant of this heterogeneous syndrome resembling the findings in neonatal lymphocytes and can be distinguished from the "adult" form of hyper-IgM syndrome which may be due to defective switch T cells.

Abstract
In the early 1970s an increased prevalence of gallstones was reported in adults and children with immunoglobulin deficiency. As the advent of ultrasonography has largely changed the diagnostic approach to gallstones, we have reevaluated the prevalence of cholelithiasis in a group including 37 patients with common variable immunodeficiency and seven patients with other forms of primary immunodeficiency. All patients were receiving intravenous gammaglobulin replacement since 1983 or, in more recent cases, soon after the diagnosis was made, and therefore had relatively few infections. All patients underwent a hepatobiliary ultrasonogram and blood sampling. Data were compared, after age and sex standardization, with those obtained by the GREPCO in a free-living population of 1239 men and 1081 women. Only two women with immunoglobulin deficiency had gallstones. One of these was obese and had had one pregnancy. Both were asymptomatic. None of the patients studied had a history of cholecystectomy or evidence of biliary sludge. Thus, the observed prevalence rates of gallstone disease were 8.7% in women and 0% in males, respectively, against expected values of 9.5% and 3.2%. Immunodeficient patients expressed several putative risk factors for gallstones in the low range (body mass index, total and HDL cholesterol, and blood glucose in both sexes, and triglycerides in men). We conclude that gallstone disease is not more frequent in patients with immunodeficiency syndromes undergoing immunoglobulin therapy than in the general population.

Abstract
We describe 2 brothers with a malformation syndrome consisting of agenesis of the corpus callosum, cutaneous hypopigmentation, bilateral cataract, cleft lip and palate, and combined immunodeficiency. The clinical history of both patients was characterized by severe psychomotor retardation, seizures, recurrent severe respiratory infections, and chronic mucocutaneous candidiasis. The children died of bronchopneumonia at age 2 and 3 years, respectively. Immunological investigations showed, in one sib studied, skin anergy to recall antigens, profound depletion of T4+ lymphocytes, and serum IgG2 deficiency. Necropsy showed agenesis of the corpus callosum, hypoplasia of the cerebellar vermis, and profound hypoplasia of the thymus and of the peripheral lymphoid tissue. The distinctive features of these sibs appear to define a previously undescribed hereditary MCA/MR syndrome. The clinical and pathological findings seem to indicate, as a pathogenetic mechanism, a defect involving the embryonic organization of the central nervous system and of the immune system.

Abstract
We report four cases of Omenn's syndrome (OS), an autosomal recessive disease characterized by early erythrodermia, protracted diarrhea, severe infections, lymphadenopathy, hepatosplenomegaly, failure to thrive, and leukocytosis with marked eosinophilia. The immunological investigations revealed B lymphopenia with increased levels of serum IgE and marked depression of T-cell activation, not restored by the addition of exogenous interleukin 2 (IL-2). IL-2 and interferon-gamma (IFN-gamma) production in vitro were very low or absent. One patient was treated with HLA-identical bone marrow transplant with a complete remission of the clinical picture and the immunological defect. The infant died of graft versus host disease 4 months after the graft. For the remaining three infants the outcome was also fatal within the first year of life. In conclusion, OS should be considered a severe combined immunodeficiency disease with peculiar clinical, immunological, and histological findings.
