Insights
A new diagnostic method for tuberculosis uses B-rosette forming lymphocytes. This test shows a significant decrease in these cells in active tuberculosis patients, aiding diagnosis.
Area of Science:
- Immunology
- Microbiology
- Medical Diagnostics
Context:
- Tuberculosis diagnosis requires effective and accessible methods.
- Current diagnostic procedures may have limitations in sensitivity or specificity.
- B-rosette forming lymphocytes are immune cells that may indicate disease presence.
Purpose:
- To introduce a novel diagnostic procedure for tuberculosis using B-rosette forming lymphocytes.
- To evaluate the diagnostic effectiveness of this new method.
- To explore the correlation between B-rosette forming lymphocytes and antiphosphatidic antibodies in tuberculosis.
Summary:
- A new method for diagnosing tuberculosis involves defining B-rosette forming lymphocytes (EAC-RFC-ph).
- Dry erythrocytic tuberculous phosphatidic diagnosticum was utilized for the first time in this reaction.
- A significant reduction in EAC-RFC-ph was observed in patients with active tuberculosis across various sites.
Impact:
- The proposed procedure demonstrates high diagnostic informativeness for tuberculosis.
- Findings suggest a potential new tool for improving tuberculosis detection rates.
- An inverse correlation was noted between antiphosphatidic antibodies and EAC-RFC-ph levels in patients and controls.
Abstract:
To increase the effectiveness of diagnosing tuberculosis, a new procedure of defining B-rosette forming lymphocytes is proposed. A commercially available product, i.e. dry erythrocytic tuberculous phosphatidic diagnosticum produced by the Leningrad Vaccine and Serum Research Institute and meant for serologic examinations and antiphosphatidic antibody detection, was used in the above reaction for the first time. The following groups were selected for the examination: 51 patients with female genital, locomotor and ocular tuberculosis; 33 persons with nonspecific diseases of the same sites; and 19 donors. A significant drop in the absolute percentage of B-rosette forming lymphocytes (EAC-RFC-ph) in patients with active tuberculosis of all sites was found out. High diagnostic informativeness of the procedure is demonstrated. There was an inverse correlation between the level of antiphosphatidic antibodies and the content of B-rosette forming lymphocytes in tuberculosis patients and the examined controls.

SN2 Reaction: Stereochemistry
If the substrate is an achiral molecule at the α-carbon, the inversion of configuration is not observed.
SN1 Reaction: Stereochemistry
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...
