IgG Stimulates the Formation of Neutrophil Extracellular Traps and Modifies Their Structure.

We studied the neutrophils and monocytes obtained from 37 patients with various inflammatory diseases such as psoriasis, acute infectious process in the abdominal cavity (acute appendicitis/abscess of the abdominal cavity, and acute cholecystitis), acute pancreatitis, and post-COVID syndrome after mild COVID infection. The number and the morphological structure of neutrophil extracellular traps (NET) as well as the effect of IgG on NET were examined. NET were visualized and counted by fluorescence microscopy with fluorescent dye SYBR Green.

[Choice of optimal vaccination tactics against pneumococcal infection from immunological and clinical standpoints in patients with chronic obstructive pulmonary disease].

Aim: To provide a rationale for choosing the optimal tactics of vaccination against pneumococcal infection in patients with chronic obstructive pulmonary disease (COPD) in the context of evidence-based medicine and on the basis of immunological and clinical data.

Subjects And Methods: Patients with COPD were examined during a year after vaccination with a 13-valent pneumococcal conjugate (Prevenar-13, PCV13) and a 23-valent pneumococcal polysaccharide (Pnemo-23, PPV23) vaccines. The following vaccination schemes were used: PCV13 monovaccination, PPV23 monovaccination, sequential vaccination with PPV23/PCV13, and sequential vaccination with PCV13/PPV23.

[The application of invasive and non-invasive reflexotherapeutic methods for the improvement of tolerance to the influence of seasonal meteorological factors and correction of bronchial asthma].

The present study included 94 patients presenting with bronchial asthma (BA) who underwent the controlled treatment during one year. The treatment consisted of basal anti-asthmatic therapy in combination with acupuncture reflexotherapy or a complex of non-invasive reflexotherapeutic methods (CNIRTM) designed to increase the effectiveness of correction of asthma, to improve the clinical status of the patients, to decrease by more than two-fold the frequency of unstable episodes of the disease showing the well-apparent seasonal dependence, and to diminish the consumption of pharmaceuticals (reduction of the mean daily dose of prednisolone by 31% and 37% in comparison with its 79% increase in the patients receiving the standard treatment). Moreover, it was shown that the achievement of clinical and preventive effect of the application of non-pharmacological methods may be associated with the activation of the mechanisms of adaptation to the stress factors (such as correction of the cortisol blood level and parameters of the immune status, etc.

[Results of adjuvant chemotherapy (XELOX) of advanced colorectal cancer].

While the most frequent, surgery for colorectal cancer is avoided in patients with metastases to the regional lymph nodes (stage III) or distant ones (stage IV). Hence, it is being increasingly substituted with neoadjuvant treatment. Our investigation is concerned with prospective evaluation of the efficacy and toxicity profile of capecitabine (XELODA) in combination with oxaliplatin (XELOX) and adjuvant Mayo treatment (stage IIb-III).

[Correlations between external respiration function and the blood content of the immune system cells in hyperventilation ].

Relations between hyperventilation, hyperventilation syndrome (HVS) and bronchial asthma (BA) are not finally established. This study modelled HVS in 92 volunteers to investigate HVS effect on external respiration function (ERF), immune status and hormonal and amino regulation. HVS was found to induce significant shifts in regulating systems (adrenergic, cholinergic, serotoninergic, conticosteroids) function and to alter correlations between ERF and blood levels of immune cells carrying various CD- and HLA-DR markers.
