Abstract
Description
Metabolite markers for differential diagnosis of Mycobacterium avium complex or Mycobacterium tuberculosis infections
[0001] The present invention relates to a metabolite marker for the differentiation or diagnosis of patients with nontuberculous mycobacterial infections and patients with tuberculosis infections.
[0002] There are currently over 72 known species of Mycobacterium, including not only species that cause serious diseases in humans and animals, such as tuberculosis, Mycobacterium bovis, and Mycobacterium leprae, but also species called opportunistic infections, and saprophytic species found in the natural environment, of which 25 species are known to be associated with human diseases. These Mycobacterium species are not easily stained with commonly used staining solutions, but once stained, they do not easily decolorize even when treated with alcohol or hydrochloric acid, which is why they are also called acid-fast bacteria. Acid-fast bacteria are divided into nontuberculous mycobacteria (NTM), Mycobacterium tuberculosis complex, and Mycobacterium leprae.
[0003] More than 180 nontuberculous mycobacterial strains have been officially identified as commonly causing lung disease in humans. The Mycobacterium avium complex (MAC) primarily includes M. avium and M. intracellulare, while Mycobacterium abscessus (MAB) primarily includes M. abscessus subspecies abscessus and M. abscessus subspecies massiliense.
[0004] Meanwhile, Mycobacterium tuberculosis (MTB) is a bacterium that causes tuberculosis and belongs to the tubercle bacilli family.
[0005] Despite the recent increase in reports of lung infections caused by mycobacteria worldwide, there is a lack of biomarkers to distinguish patients with lung infections caused by Mycobacterium avium complex (MAC), a nontuberculous mycobacterium that is particularly common in humans and causes lung diseases, from patients with lung infections caused by Mycobacterium tuberculosis, or studies on the pathophysiology of the disease.
[0006] Accordingly, the inventors of the present invention have completed the present invention by discovering a metabolite that can serve as a biomarker that can rapidly differentiate and diagnose two diseases with similar clinical manifestation characteristics by comparing and analyzing the metabolites of serum samples at the time of diagnosis of a patient infected with Mycobacterium tuberculosis (Mtb) and at the time of diagnosis of a patient infected with Mycobacterium avium complex (MAC).
[0007] The present inventors have conducted extensive research to discover objective and reliable diagnostic markers that can rapidly differentiate between Mycobacterium avium complex (MAC) infection and Mycobacterium tuberculosis (Mtb) infection, two diseases with very similar clinical manifestations. As a result, we have discovered 17 polar and lipid metabolites that can be reflected as diagnostic markers with high reproducibility and reliability in differentiating between Mycobacterium avium complex infection and Mycobacterium tuberculosis infection.
[0008] Therefore, the purpose of the present invention is to provide a composition for differentiating between nontuberculous mycobacterial infections and tuberculosis infections.
[0009] Other objects and advantages of the present invention will become more apparent from the detailed description, claims and drawings below.
[0010] According to one aspect of the present invention, the present invention provides a composition for differentiating between nontuberculous mycobacterial infections and tuberculosis infections, comprising as an active ingredient a preparation for measuring one or more metabolites selected from the group consisting of lipid metabolites, amino acids and amino acid derivatives.
[0011] The lipid metabolite is at least one selected from the group consisting of palmitamide, stearamide, oleamide, linoleamide, behenamide, anandamide (arachidoyl ethanolamide), stearamine, behenic acid, lyso phosphatidylethanolamine (Lyso PE), sphinganine, sphingosine, and dimethylsphingosine.
[0012] The composition is characterized in that the amino acid and amino acid derivative are at least one selected from the group consisting of 2-hydroxyglutaric acid, allantoin, choline, and uric acid.
[0013] The present inventors have conducted extensive research to discover diagnostic markers for differentiating patients infected with nontuberculous mycobacteria (NTM), particularly Mycobacterium avium complex (MAC), which is a very common cause of lung disease in humans, and Mycobacterium tuberculosis (MTB), which has very similar clinical characteristics and thus makes the development of objective and reliable differential markers difficult. As a result, we have discovered 31 polar metabolites and 97 lipid metabolites as differential diagnostic markers that can reflect infectious diseases caused by nontuberculous mycobacteria or tuberculosis with high reproducibility and reliability.
[0014] In this specification, the term "nontuberculous mycobacteria" refers to mycobacteria other than tuberculosis bacilli, and specifically includes all mycobacteria that do not cause tuberculosis or leprosy. Unlike general bacteria, mycobacteria refer to strains that have the ability to withstand and not dissolve when acid is added during the staining process. The most representative of these mycobacteria is Mycobacterium tuberculosis, and acid-fast bacteria other than tuberculosis bacilli are called nontuberculous mycobacteria (NTM), and new nontuberculous mycobacteria are discovered almost every year.
[0015] As used herein, the term "tuberculosis bacilli" refers to acid-fast bacilli other than non-tuberculosis bacilli, specifically all mycobacteria that do not cause non-tuberculosis or leprosy. Unlike typical bacteria, acid-fast bacilli are strains that can withstand and remain insoluble even when acid is added during the staining process. A representative example of these acid-fast bacilli is Mycobacterium tuberculosis, which is characterized by high pathogenicity and a high relapse rate after treatment.
[0016] As used herein, the term "differentiation" may refer to the classification and subdivision of a specific disease or condition present in an individual. In the present invention, differentiation refers to the evaluation of a condition based on objective markers that can objectively distinguish and identify multiple diseases with similar clinical characteristics.
[0017] As used herein, the term “differential diagnostic composition” refers to an integrated mixture or device including a means for measuring the concentration of lipid metabolites, amino acids or amino acid derivatives to determine whether a subject is infected with nontuberculous mycobacteria or tuberculosis bacteria, and may be expressed as a “differential diagnostic kit.” Since the differential diagnostic composition of the present invention includes a means for measuring the metabolites discovered in the present invention, the term “differential diagnostic composition” may also be expressed as a “quantitative device” for the metabolites.
[0018] The term "metabolite" herein, also known as a metabolite or metabolite, refers to an intermediate or product of metabolism. These metabolites have diverse functions, including fuel, structure, signaling, enzyme stimulatory and inhibitory effects, their own catalytic activity (typically as a cofactor for enzymes), defense, and interactions with other organisms (e.g., pigments, aromatic compounds, pheromones). Primary metabolites are directly involved in normal growth, development, and reproduction. Secondary metabolites are not directly involved in these processes, but often have important ecological functions.
[0019] According to the present invention, the metabolite refers to a metabolite obtained from a sample of biological origin, i.e., a biological sample, and the biological sample refers to a biological fluid, tissue or cell.

[0042] In the present invention, lipid metabolites, amino acids and amino acid derivatives, which are measurement targets for the differentiation of nontuberculous mycobacteria or tuberculosis bacteria, have already been described above, and therefore, their description is omitted to avoid excessive duplication.

[0059] Hereinafter, the present invention will be described in more detail through examples. These examples are intended solely to illustrate the present invention more specifically, and it will be apparent to those skilled in the art that the scope of the present invention is not limited by these examples, in accordance with the gist of the present invention.
[0060]
[0061] Preparation Example 1. Collection of samples from patients with pulmonary disease infected with Mycobacterium tuberculosis and patients with pulmonary disease infected with MAC.
[0062] The present invention collected 100 serum samples at the time of diagnosis from 100 patients with lung disease infected with Mycobacterium tuberculosis (Mtb) at Seoul National University Hospital over a period of approximately 3 years from October 2010 to June 2013, and 81 serum samples at the time of diagnosis from 81 patients with lung disease infected with Mycobacterium avium complex (MAC) at Seoul Samsung Hospital over a period of approximately 6 years from January 2017 to May 2022.
[0063]
[0064] Preparation Example 2. Pretreatment of the sample
[0065] 2.1 Sample pretreatment for polar metabolite analysis
[0066] For the analysis of polar metabolites in serum, the serum sample obtained in Preparation Example 1 was pretreated. Specifically, 290 μl of 70% ACN (Acetonitrile-H2O, 70:30, v / v) was added to the serum sample (10 μl) for extraction, and at this time, an internal standard (13C-labeled yeast extract; ISO+13C-taurine 1000 ppb, 13C-allantoin 1000 ppb, 13C-hypoxanthine 100 ppb, 13C-2-chloro adenosine 1000 ppb, 13C-Lactate 100 ppb, 13C-Glucose 1000 ppb, 13C-Uric acid 1000 ppb) diluted 1:30 was added to the solvent for quality control of the polar metabolite analysis. Here, the internal standards are shown in Tables 4 and 6 below. After mixing for 30 seconds, extraction was performed on ice for 10 minutes. After centrifugation at 13,000 rpm and 4°C for 10 minutes using a centrifuge, the supernatant, excluding the precipitate, was filtered using a filter tube (Costar 8169) to remove possible impurities, and then polar metabolite analysis was performed using an HPLC-QQQ-MS instrument.
[0067] 2.2 Sample preparation for lipid metabolite analysis
[0068] For analysis of lipid metabolites in serum, the serum sample obtained in Preparation Example 1 was pretreated. Specifically, 300 μl of CHCl3 and 150 μl of MeOH (Chloroform-Methanol, 2:1, v / v, 4°C) were added to the serum sample (40 μl) and mixed for 30 seconds. Additionally, 150 μl of water was added, mixed for 30 seconds, and extracted on ice for 10 minutes. After centrifugation at 13,000 rpm and 4°C for 10 minutes, the lower layer (250 μl) was separated and dried using a liquid nitrogen concentrator (low temperature -195°C, 30 minutes). The supernatant was re-dissolved in 250 μl of IPA / ACN / H2O (Isopropanol-Acetonitrile-Water, 2:1:1, v / v). At this time, the SPLASH_Lipido MIX internal standard was added in a 1:50 dilution to the re-dissolution solvent of the supernatant to control the quality of lipid metabolite analysis. After filtration using a filter tube (Costar 8169) to remove possible impurities, lipid metabolite analysis was performed using a UPLC-Q-Exactive Orbitrap / MS instrument.
[0069] In order to control the quality of the sample and device during the preprocessing of the above serum sample, 20 μl of the entire sample was collected to create a QC, and repeated measurements were made by inserting the sample between batches to measure the difference in the analysis quality of the sample and device within each batch.
[0070]
[0071] Example 1. Metabolite analysis using HPLC-Triple Quad (QQQ)-MS
[0072] To analyze polar metabolites in the processed serum samples, liquid chromatography-tandem mass spectrometry (HPLC-QQQ-MS) was used. The equipment used was an Agilent 1200 HPLC and a SCIEX API4000 triple quadrupole MS. The positive mode analysis conditions for polar metabolites using HPLC were a gradient elution with a solvent at 40 °C using an XBridge BEH Amide (4.6 x 250 mm, 3.5 μm, Waters) column. The mobile phases used were (A) 85% Water + 15% Acetonitrile (30 mM ammonium acetate + 0.2% acetic acid) and (B) 85% Acetonitrile (0.2% acetic acid). The negative mode analysis conditions for polar metabolites were as follows: a Luna PFPP (2.0 x 150 mm, 3 μm, Phenomenex) column was used, and gradient elution was performed at 40 ℃ according to the solvent, and (A) Water (0.1% formic acid) and (B) 100% Acetonitrile were used as the mobile phases. The gradient elution for each condition was performed as shown in Tables 1 and 2 below, and the total analysis time was 17 minutes and 15 minutes, respectively. The mass analysis conditions using MS / MS were as follows: the nebulizer gas (Ion-Source Gas 1 / 2) unit was 50 / 50 arbitrary unit, and the curtain gas unit was set to 25 arbitrary unit. The source temperature was 500 ℃, the ion-spray floating voltage was 5.5 kV (negative -4.5 kV), and the mass range was 50-1000 m / z.Sample injection was performed at 3 μl per injection using the HTC_PAL system / CTC analytics auto-sampler, and the tandem mass spectrometry conditions (scheduled multiple reaction monitoring, sMRM) were performed as shown in Tables 3 to 6 below. The results obtained through sMRM analysis were converted to raw data using SCIEX's Quantitative Analysis Software, and polar metabolites with a relative standard deviation (RSD<20) or less were calculated using the average value of QC data.

[0088] Example 2. Lipid metabolite analysis using UPLC-MS (Q-Exactive Ortbitrap Plus)
[0089] To analyze lipid metabolites in the analytical samples isolated from serum, chromatography-tandem mass spectrometry (UHPLC-MS) was used. The equipment used was Thermo Scientific's Ultimate 3000RS pump UHPLC and Q-Exactive Orbitrap Plus MS. The chromatographic conditions for hydrophilic interactions were an Acquity UPLC BEH C18 (2.1 x 100 mm, 1.7 μm, Waters) column and gradient elution at 35 °C to separate lipid metabolites. The mobile phases used were (A) 10 mM ammonium formate in 50% ACN + 0.1% formic acid (v / v) and (B) 2 mM ammonium formate in ACN / IPA / Water 10:88:2 + 0.02% formic acid (v / v). The gradient elution of the following mobile phase was performed in the same manner as in Table 7 below, with a total analysis time of 28 minutes. Electrospray ionization (ESI) was performed with two ionization modes: positive and negative. The full scan mass range was 250-1200 m / z, with a resolution of 70,000. The automatic gain control (AGC) target was 1x106 ions, and the maximum injection time (IT) was 100 ms. The collision energy (CE) was 30, the source ionization spray voltage was 3.0 kV, and the capillary temperature was 370 ℃. The results obtained through the analysis were analyzed using Thermo Scientific's analysis software (Compound Discoverer 3.2) Raw data was produced through alignment and normalization, and lipid metabolites with a relative standard deviation (RSD<20) or less were produced after statistical processing.

[0092] Example 3. Results of metabolite analysis in serum samples from patients infected with Mycobacterium tuberculosis and MAC infection.
[0093] In order to differentially diagnose two diseases with similar clinical manifestations, the identification and concentration of polar and lipid metabolites in serum samples from patients with MTB and MAC infection were compared using the following statistical test methods. For the statistical test methods, Metaboanalyst, metilin, lipidmaps and hdmb (statistics site, Database) and Quantitative Analysis Software of SCIEX, Compound Discoverer of Thermofisher, SPSS (statistics program) were used to derive polar and lipid metabolites with high significance (p<0.05, FC≤-0.12, 0.12≤FC) between the two groups. Based on the results, a total of 128 metabolites, including 31 polar metabolites and 97 lipid metabolites that could be indicators for differential diagnosis of the two diseases, were selected based on their respective p-values and Fold change values, and the results are shown in Tables 8 and 9 and Figures 1 to 4 below. Among them, the four polar metabolites and 13 lipid metabolites with high AUC values (AUC>0.8 or higher) were each represented by ROC curves, and a total of 17 metabolites including all four polar metabolites and 13 lipid metabolites were represented by ROC curves. The results are shown in Figures 5 to 7. At this time, significance means *P<0.05; **P<0.01; ***P<0.001 in unpaired Welch's t-test.
