Gastritis Can Cause and Trigger Chronic Spontaneous Urticaria Independent of the Presence of Helicobacter pylori.

Background/aim: In chronic spontaneous urticaria (CSU), Helicobacter pylori (HP) has been discussed as a cause, but it is unknown whether the bacterium itself or concomitant inflammation is causing the urticaria. Our aim was to investigate HP and upper gastrointestinal lesions as signs of inflammation independently of each other in the pathogenesis of CSU.

Methods: A total of 36 prospectively enrolled CSU patients from Moscow were investigated by gastroscopy and screened for the presence of HP and/or upper gastrointestinal lesions.

[Neutrophil bactericidal and absorptive function in gout].

Aim: To study neutrophil bacterial and absorptive functions and the specific features of their impairments in gout.

Subjects And Methods: The study included 48 male patients with a valid diagnosis of gout (mean age, 59.7 +/- 10.

Pathogenetic aspects of severe course of herpetic infection.

We studied the state of antiviral defense in patients with severe course of herpetic infection of anogenital and labial localization and the frequency of its combination with other herpes virus infections. It was found that severe course of herpetic infection caused by herpes simplex virus occurs against the background of combined secondary immunodeficiency and its complication. We first demonstrated that severe course of the disease is associated with mixed viral infection.

[Severe herpetic infection].

Aim: To study antiviral defense in patients with severe anogenital and labial herpetic infection, prevalence of herpetic infection and possible combination with other strains.

Material And Methods: The immune status (basic lymphocyte subpopulations, IgA, IgM, IgG, circulating immune complexes in blood serum, cytokines, interferon status, functional activity of neutrophils) was investigated in 102 patients with severe Herpex simplex infection (HSI).

Results: Marked deficiency and hyporeactivity of natural and/or specific cytotoxicity were found in 70% HSI patients with severe disease.

[Individual changes of gene expression in the interferon system in human blood cells due to amixin and cycloferon].

The action of amixin and cycloferon on the expression of genes in the systems of interferon (IF) and cell apoptosis (CA) was studied by semi-quantitative RT-PCR in human blood microsamples before and after the administration of the drugs. Individual changes were determined in the transcription activity of genes of IF (alpha, beta, gamma), enzymes 2',5' oligoadenylatesynthetase (OAS), RNSase L, dsRNA-dependent proteinkinase (dsPK) and of CA effectors (FasAg, bcl-2, gamma-actin) registered dynamically in 24 h and 48 h. The activity parameters of IF genes were compared with the results of biological titration of IF activity in blood samples in vivo and in vitro.

[Drug intolerance].

The authors present experimental data on luminol-dependent neutrophil chemiluminescence of blood from patients with drug intolerance. A decrease in intensity of neutrophil and whole blood chemiluminescence was registered in the presence of intolerated drugs. In acute phase of generalized intolerance reaction the chemiluminescence test showed readiness of the blood cells to react inadequately to the contact with different drugs leading to variations in generation of active oxygen forms.

[The clinical efficacy and pharmacokinetic characteristics of theopek and theobiolong in bronchial asthma patients].

The pharmacokinetics of theopec (TP) and theobiolong (TB) was studied and compared to theotard and durophylline in 24 bronchial asthma patients. The efficacy of the continuous use of TP and TB was examined in 64 patients. Theophylline (TPh) was absorbed from TP tablets according to the laws of the kinetics of the first order, i.

[Bronchoconstrictive and bronchodilating effects of acetylsalicylic acid in patients with bronchial asthma].

An aspirin test has been performed in 100 asthma patients. The response of the bronchi appeared contradictory: aspirin asthma on the one hand, and bronchodilatation on the other occurred in 31 and 28 patients, respectively; 41 patients appeared nonresponders. Maximum effect of the drug was noted in the small bronchi.

[The effect of the plasma of patients with asthma of physical effort on the energy state of the lymphocytes].

The effect of the plasma obtained before and after graded submaximal exercise was examined in 10 bronchial asthma patients with the syndrome of asthma of physical effort (APE) by means of fluorescent exploration using the cation probe 4-(p-demethylaminostyryl)-1-methylpyridinum and rat thymocytes as a test system. Four normal donors and five bronchial asthma patients without the APE syndrome were used as control. The plasma of patients with the APE syndrome, obtained after physical exercise, brought about a decrease of the number of fluorescent cells.

[Hemosorption in the treatment of aspirin-induced bronchial asthma].

Oral aspirin test was performed in 50 asthma patients. Of them 18 patients exhibited idiosyncrasy to the drug. All the patients were subjected to hemosorption.

[A case of hereditary angioneurotic edema provoked by functional insufficiency of C1-inactivator].

The hemolytic activity of complement, the concentration of C1-inactivator, of C1q and C4 components of complement as well as the activity of contact-activated kallikrein and the functional activity of C1-inactivator were studied in the plasma of a female patient with hereditary angioneurotic edema (HAE), of her mother, sister and normal donors. The hemolytic activity of complement, the concentration of C1-inactivator and C1q in the blood plasma of the persons examined turned out unchanged as compared with the same parameters in donors. Meanwhile in the patient with HAE and her mother with symptoms similar to HAE, the concentration of C4 appeared lower than that in the patient's sister not suffering from the disease and in donors.
