Cross-reactivity of anti-ssDNA antibodies with heparan sulfate in patients with type I diabetes mellitus
1989
Anti-single-stranded–DNA antibodies cross-reactive with heparan sulfate were detected in serums of patients with type I (insulin-dependent) diabetes mellitus. The results suggested that heparan sulfate, the major glycosaminoglycan constituent of the glomerular basement membrane, may serve as a target antigen in vivo for cross-reactive anti-DNA antibodies. These polyreactive antibodies, directed toward repeating negatively charged units, may neutralize the heparan sulfate–associated polyanionic sites in the glomerulus, leading to an abnormal permeability of anionic plasma proteins.
Higher levels of IgA and IgG at sepsis onset are associated with higher mortality: results from the Albumin Italian Outcome Sepsis (ALBIOS) trial
2021
Abstract Background The role of intravenous immunoglobulins (IVIG) during sepsis is controversial, as different trials on IVIG have observed inconsistent survival benefits. We aimed to elucidate the possible association and clinical significance between circulating levels of immunoglobulins. Methods In a subset of 956 patients with severe sepsis and septic shock of the multicentre, open-label RCT ALBIOS, venous blood samples were serially collected 1, 2, and 7 days after enrolment (or at ICU discharge, whichever came first). IgA, IgG and IgM concentrations were assayed in all patients on day 1 and in a subgroup of 150 patients on days 2 and 7. Ig concentrations were measured employing a tur…
Influence of artificial blood contamination of the analysis of cerebrospinal fluid
1981
The influence of artificial blood contamination on the quantitative values obtained in the routine examination of the CSF was investigated. On the basis of dilution series from CSF and blood, the correlation between the number of added erythrocytes and the results of leukocyte counts, protein, glucose and IgG estimation was studied. In addition, the influence of the time between CSF sampling and investigation on erythrocytes and leukocytes, IgG, glucose, pH value and ammonia content in CSF contaminated with blood was investigated. The following data relevant to routine examinations resulted: there are linear correlations between the number of erythrocytes artificially added to the CSF and t…
Comparative effects of UVA and UVB irradiation on the immune system of fish.
2000
Aquatic organisms can be harmed by the current levels of solar ultraviolet radiation. We have recently shown that exposure of fish to UVB irradiation alters the functioning of the fish immune system, but the effects of UVA radiation are unknown. The present study continues this work by characterizing UVA irradiation-induced immunological changes in fish. Roach, a cyprinid fish, were exposed to a single dose of either UVA (3.6 J/cm2) or UVB (0.5 J/cm2) irradiation. Both irradiations suppressed transiently mitogen-stimulated proliferation of blood lymphocytes. UVA, but not UVB, decreased hematocrit, plasma protein, and plasma immunoglobulin levels and increased the proportions of blood cells …
Sustained safety and efficacy of ligelizumab in patients with chronic spontaneous urticaria: A one‐year extension study
2021
Background: Ligelizumab, a next-generation, humanized anti-immunoglobulin E (IgE) monoclonal antibody is in development as a treatment for patients with chronic spontaneous urticaria, whose symptoms are inadequately controlled with standard-of-care therapy. Objective: To evaluate the long-term safety and re-treatment efficacy of ligelizumab 240 mg in patients who completed the core study and extension study. Methods: This open-label, single-arm, long-term Phase 2b extension study was designed to assess patients who were previously administered various doses of ligelizumab, omalizumab or placebo in the Phase 2b, dose-finding core study and who presented with active disease after Week 32. In …
STAT3 ‐mutated hyperimmunoglobulin E syndrome with perianal skin tags and erosions: A case report
2020
Long-term efficacy of omalizumab (OMA) for patients with severe allergic asthma (SAA). Clinical assessment and relationship to serum IgE concentratio…
2015
Background: OMA is an effective treatment option in SAA. However, little data are available on the long-term-efficacy oft the drug. Objective: To determine the long-term efficacy of OMA in respect to clinical parameters and IgE serum levels. Methods: This was a retrospective, open-label, uncontrolled, multi-center observational study according to the definition of non-interventional studies. 22 non-smoking patients (10 m, 12 f; mean age 47,9 yrs) with SAA were enrolled. Pat were treated with OMA up to for 4 years and total serum IgE levels were assessed at initiation of therapy, after 2-6 ms and 3-5 yrs. Data were recorded on standardized CRFs by the treating physician. Results: The average…
Intolerance to hydrolysed cow's milk proteins in infants: clinical characteristics and dietary treatment
2000
Summary Background Multiple food intolerance in infants, including intolerance to extensively hydrolysed proteins (HP), is often difficult to treat. However, few data have been reported on clinical outcome and dietary treatment of these patients. Aims To evaluate the clinical characteristics of patients with HP-intolerance and the longterm outcome of treatment with ass’ milk. Patients and Methods This study included 21 HP-intolerant infants (15 males, median age at diagnosis 2 months) treated with an ass’ milk-based diet and 70 cow’s milk (CM) intolerant infants (40 males, median age at diagnosis 3 months) treated with casein hydrolysate milk-based diet. All patients were followed-up for a …
Patterns of changes of anti‐ADAMTS13 after plasma exchange
2006
An enzyme-linked immunosorbent assay (ELISA) has recently been developed to detect antibodies against the von Willebrand factor-cleaving protease ADAMTS13 in patients with thrombotic thrombocytopenic purpura (TTP). The ELISA is based on incubation of plasma with immobilized recombinant ADAMTS13 followed by visualization of IgG and IgM antibodies by means of secondary enzyme-labeled antibodies [1]. In a recent study, anti-ADAMTS13 IgG antibodies were detected in most patients with TTP (97%) characterized by severe ADAMTS13 deficiency (< 10% of normal) [1]. The ELISA was more sensitive than the standard inhibitor assay based upon ADAMTS13 neutralizing activity, which gave positive results in …
