Interleukin 3 in the treatment of chemotherapy induced thrombocytopenia.
1998
We enrolled 19 cancer patients (11 females, 8 males) with thrombocytopenia after standard dose of chemotherapy to receive IL3 10 mg/kg/day s.c. until hematologic recovery. Therapeutic success was obtained in 69.6% of cycles; a major response in 39.3% and a minor response in 30.3% of cycles. We obtained the best results in case of platelet count <49,000/mm3. The main toxicity was a flu-like syndrome. In two cycles (6%) we registered allergic episodes with flushing and lipothymia. In the 47% of cycles evaluable for toxicity no side effect was registered.
A double blind controlled trial comparing three treatment modalities for dentin hypersensitivity
2011
Aim: This randomized, double blind, split mouth study was aimed to compare three dentin desensitizing treatment modalities. Methods: Two hundred sixty teeth of 25 patients; each having at least 2 hypersensitive teeth in each quadrant, were included. Teeth were randomized to 4 groups: Group A treated with 2% NaF solution, Group B received GLUMA®; an aqueous solution of Hydroxy-Ethyl-Methacrylate and Glutarldehyde, (HEMA-G), Group C received iontophoresis with distilled water (placebo) and Group D was treated with NaF-iontophoresis. Pain response was evaluated on a visual analogue scale (VAS), by using tactile, air blast and cold-water stimuli at 0-day, 15-day, 1-month and 3-months interval. …
Influence of allergic disorders on physical development
2010
Abstract The aim of the paper was to asses the relationship between socioeconomic status, the prevalence of allergy and physical development. The data were obtained from 478 female students and 195 male students aged 19-24. The prevalence of allergy in the group surveyed was 14.6% (14.6% in women and 14.4% in men). Allergic diseases were more frequent in students of high socioeconomic status. The results of the analysis of variance did not show any significant differences in anthropometric characteristics between students with and without allergies. However, women and men with allergies diagnosed are on average shorter than people without allergies. The dependency is also visible after adju…
Perioperative nonspecific histamine release : a new classification by aetiological mechanisms and evaluation of their clinical relevance
1993
As a consequence of the performance of a randomized controlled clinical trial on perioperative histamine release and cardiovascular and respiratory disturbances, several types of increases in plasma histamine had to be distinguished instead of only two which existed at the beginning of the study: drug-induced allergic and pseudoallergic reactions. First of all, the new classification by aetiology (clinical epidemiology) was derived from a meta-analysis (secondary analysis) of the most recent literature. According to that histamine release in the perioperative period has several, different causes and is involved in several, different disease manifestations. A clear distinction (classificatio…
Ketorolac, diclofenac, and ketoprofen are equally safe for pain relief after major surgery
2002
Background Ketorolac is approved for the relief of postoperative pain but concerns have been raised over a possible risk of serious adverse effects and death. Two regulatory reviews in Europe on the safety of ketorolac found the data were inconclusive and lacked comparison with other non-steroidal anti-inflammatory drugs. The aim of this study was to compare the risk of serious adverse effects with ketorolac vs diclofenac or ketoprofen in adult patients after elective major surgery. Methods This prospective, randomized multicentre trial evaluated the risks of death, increased surgical site bleeding, gastrointestinal bleeding, acute renal failure, and allergic reactions, with ketorolac vs di…
Isolated hevein-like domains, but not 31-kd endochitinases, are responsible for IgE-mediated in vitro and in vivo reactions in latex-fruit syndrome.
2005
Background Individuals with natural rubber latex allergy often have immediate reactions to plant-derived foods and fresh fruits, such as avocado and banana. IgE of these patients has been shown to bind endochitinases containing an N-terminal hevein-like domain (HLD). However, evidence on 31-kd endochitinase-induced reactions in vivo is lacking. Objective We sought to assess the clinical significance of 31-kd endochitinases and isolated HLDs in latex-fruit syndrome. Methods The 31-kd endochitinases and corresponding HLDs were purified or produced from avocado, banana, latex, and wheat germ. Skin prick test reactivities against purified proteins were examined in 15 patients with natural rubbe…
Aspirin Intolerance in Patients with Chronic Sinusitis
1999
Aspirin intolerance in patients with chronic sinusitis is often a cause of early recurrence of symptoms after surgical treatment. This study assesses 84 patients who were tested for acetylsalicylic acid intolerance after presenting with symptoms like chronic rhinosinusitis, sometimes bronchial asthma, coexisting allergies or a history of aspirin sensitivity. Nasal polyposis was found in a majority of cases, often recurrent after previous surgery. The levels of eicosanoids such as peptido-leukotrienes and prostaglandin E<sub>2</sub> were analyzed in isolated blood cells and compared with a healthy control group. Aspirin-intolerant patients showed elevated basal levels of peptido-…
Increased in vitro cvsteinvl leukotriene release from blood leukocytes in patients with asthma, nasal polyps, and aspirin intolerance
1996
In vitro cysteinyl leukotriene (cLT) release from blood leukocytes was measured in eight normal individuals (NI), nine patients with nasal polyps (NP) without aspirin intolerance, and eight patients with NP, asthma, and aspirin intolerance (AI). Blood leukocytes were prestimulated with interleukin-3 (IL-3) and incubated with acetylsalicylic acid (ASA) (10 and 100 micrograms/ml) together with C5a (10(-8) mol/l) for 18 h. cLT release (LTC4, LTD4 and LTE4) from blood leukocytes was measured with a competitive enzyme-linked immunoassay. Background cLT release was 259 +/- 66 pg/ml (mean +/- SEM) in the NI group, 185 +/- 33 pg/ml in the NP group, and 578 +/- 136 pg/ml in the AI group (P = 0.1). A…
A case of agammaglobulinemia characterized by a defect of B-lymphocyte-differentiation to plasma cells
1974
Humoral and cell-mediated immune reactions of a 36-year old patient with a late onset of an agammaglobulinaemia and of his immediate relatives have been investigated. The immunoglobulins gamma-G, gamma-A, gamma-M, gamma-E and gamma-D, and plasma cells in the bone marrow could not be detected in the patient's serum. Immune reactions with PPD and tetanus toxoid as well as the stimulation of the lymphocytes with PHA indicate that the T-cell system was intact. The examination of the peripheral blood lymphocytes by immunofluorescence techniques gave a normal number of B-lymphocytes. These findings could be corroborated by the results of lymphocyte stimulations with anti-IgG. The data suggest tha…
Low SPINK5 expression in chronic rhinosinusitis
2012
Objectives/Hypothesis: Chronic rhinosinusitis (CRS) is a multifactorial disease that probably arises as a result of genetic diversity and environmental factors. SPINK5 is a serine protease inhibitor, which is supposed to be an important regulator of epithelial barrier maintenance. The role of SPINK5 polymorphisms and expression in CRS, especially in individuals with aspirin intolerance, is unclear. Study Design: SPINK5 single-nucleotide polymorphisms (SNPs) and SPINK5 expression levels were correlated with CRS without (CRSsNP) and with nasal polyps (CRSwNP), aspirin intolerance, asthma, and allergies. Methods: One hundred four nasal tissue samples, 15 from patients with CRSsNP, 59 from pati…
