Introduction

The main factors of pathogenesis in the pulmonary tuberculosis are not only the bacterial acridity and perceptivity of the host vulnerable system to the pathogen, but also the degree of destruction of the lung kerchief. analogous destruction processes lead to the development of caves, in utmost cases taking surgical interventions besides the drug remedy. Identification of special biochemical markers allowing to assess the necessity of surgery or remedy extension remains a challenge. We consider promising markers metalloproteinases assaying the data attained from cases with pulmonary tuberculosis infected by different strains of Mycobacterium tuberculosis. We argue that the presence of drug- resistant strains in lungs leading to complicated clinical prognostic could be justified not only by the difference in middles of biomarkers attention( as determined by the Mann- Whitney test for small samples), but also by the qualitative difference in their probability distributions( as detected by the Kolmogorov- Smirnov test). Our results and the handed raw data could be used for further development of precise biochemical data- predicated individual and prognostic tools for pulmonary tuberculosis.

Pulmonary tuberculosis (TB) has a long history as a major complaint in humans and brutes. In 2017,1.7 million people failed from the complaint mainly in developing countries. A causative agent of TB Mycobacterium tuberculosis (MTB)- causes severe implications for a case generally associated with lung kerchief destruction. By now, there is a large group of cases with extensive drug- resistant (XDR) andmulti- medicine resistant (MDR) tuberculosis taking not only a long- term treatment using the newest drugs, but also surgical intervention. therefore, unravelling mechanisms of lung kerchief destruction and the quest for possibilities of early opinion and new approaches to the treatment of this pathology remain on the top of the program for recent disquisition [1].

Description

One of the promising individual directions is a discovery of specific predictors or biomarkers allowing for assessing the necessity of surgical intervention or remedy extension. The" quest for biomarkers" is an established approach in biomedicine especially for cancer and neurodegenerative conditions. It's aimed at chancing specific molecules whose attention or exertion can either define the pathological process localization or prognosticate not only the remedy success, but also the pathology elaboration. At the same time, analogous approach to tuberculosis is in its first stages in malice of a recent high demand. A promising candidate for possible biomarkers is a group of special enzymes- matrix metalloproteinases( MMP), involved in the destruction of the lung kerchief. Under normal conditions, ultimate of the MMPs are not expressed; still, their overexpression is observed during inflammation [2].

The intensity of MMP- expression is regulated byanti- seditious cytokines and bacterial lipopolysaccharides. MMP- enzymes are synthesized asproenzymes, actuated at thepost- translational position with participation of proteases and regulated by specific kerchief impediments (TIMPs, α2- macroglobulin). The part of MMPs in the destruction of the connective kerchief of the lungs mainly conforming of collagen- the main structural protein of the lung- caused by Mycobacterium tuberculosis (MBT) has not yet been fully excavated. Still, several types of metalloproteinases (MMP- 9) were linked, varying their attention situations with the development of the pulmonary tuberculosis. The main part in the induction of the destruction process of type I collagen is attributed to MMP- 1. MMP- 8 is an element of neutrophilic fractions modulating the exertion of chemokines. Its increase in pulmonary tuberculosis together with MMP- 9 reflects the strictness of the destructive process. During effective treatment, MMP attention reduces [3].

The data were attained from 234 cases with pulmonary tuberculosis (TB) treated at the State Research Institute of Phtisiopulmonology (SRIP) in the time period of 2009- 2017. The average age of the cases was35.6 ±0.8 times. There were 145 men and 88 women. All eligible cases gave their concurrence to partake. There are some missing values in the dataset due to the lack of clinical data saved as handwritten records in the Institute’s sanitorium. The healthy group (20 persons) was chosen among scientists and clinicians of SRIP in such a way that the average age was harmonious with the case cohort. still, for the control group, only data on clinical markers (TIMP- 1, MMP- 1, MMP- 8, MMP- 9) were available. For further analysis, TIMP- 1 will be substantiated as TIMP [4].

There were two groups of cases with diagnosed (by reckoned tomography, CT) forms of pulmonary tuberculosis infiltrative TB (ITB) and fibro- cavernous TB (FCTB). The first group includes cases examined at the Institute for the first time and who were not treated yet. Cases with the FCTB form anticipated a surgical intervention and formerly took a course of the treatment to repress a bacteria excretion. The details of marker attention measures and CT procedures are given in the styles section below. The introduced dataset includes the information on the biomarkers’ attention recorded and the characteristics of tuberculosis forms, analogous as a number of inflammation foci, the kerchief destruction volume and the total lesion volume. Information about drug- resistance (multi-drug,extra-drug and sensitive) of M. tuberculosis strains was also handed. As an appurtenant material, some fresh general characteristics of cases gender, body mass index,etc. are added when they were available in medical records [5].

Conclusion

In this donation, we present clinical data on attention of metalloproteinases and their asset, which could be useful to reveal biomarkers for the strictness of an inflammation process in the pulmonary tuberculosis. Due to the limited sample size, still, it's rather delicate to surely assert which markers characterize the strictness of the complaint process. still, as saying the data using two different tests (Mann – Whitney U and Kolmogorov – Smirnov) made it possible to identify some trends. The large number of outliers for resistant TB might indicate the actuality of a heavy- tagged distribution. It implies that extreme events of spare large MMPs attention might indicate a possible presence of the drug- resistant strain in a case’s organism. also, our approach provides an fresh insight related to the statistical analysis of analogous kind of clinical data.
