AbstractCurrently, the management of pulmonary tuberculosis (TB) lacks potent medications and accurate efficacy evaluation biomarkers. In view of the fact that the host lipids are the important energy source of Mycobacterium tuberculosis (Mtb), UPLC-MS/MS based on lipid metabolism was used to monitor the plasma lipid spectrum of TB patients from the initial diagnosis to cured. The analysis showed that TB patients presented aberrant metabolism of phospholipids, glycerides, and sphingolipids. Upon the treatment, the abnormal expression of Cer (d18:1/24:0), CerP (d18:1/20:3), LPE (0:0/22:0), LPA (0:0/16:0), and LPA (0:0/18:0) in TB patients were gradually normalized, indicating that the intervention of lipid metabolism could block energy metabolism and inhibit the cell wall synthesis of Mtb. Furthermore, the increase in ceramide (Cer) levels could promote autophagosome–lysosome fusion. LPA (0:0/16:0) and LPA (0:0/18:0) had a great potential in the early diagnosis (both sensitivity and specificity were 100%) and efficacy evaluation (both sensitivity and specificity were 100%) of TB, indicating that the above lipid metabolites could be used as potential biomarkers for TB.

Tuberculosis is an infectious disease caused by tuberculosis mycobacteria of human or bovine types and is characterized by multiple organs failure and chronic recurrent course. The blood plasma lipid spectrum state is one of the antituberculous chemotherapy toxic effect markers. The important role of the ratio of various fractions of general and blood phospholipids for the evaluation of the state of the organism in infectious pathology is proved. The purpose of this work is to study the features of the lipid spectrum of blood plasma in patients with pulmonary tuberculosis prior to treatment and at the end of the intensive phase of antituberculous chemotherapy. Three hundred and eight young and middle-aged patients with pulmonary tuberculosis were examined. The lipid and phospholipid spectrum of blood was determined prior to initiating the antituberculous chemotherapy and after the end of the intensive phase. The absolute content of general lipids and total phospholipids of blood plasma, as well as all their fractions, in patients with pulmonary tuberculosis were higher than in healthy volunteers. In this regard, the representation of the lipid spectrum in absolute units does not reflect all the features of lipid metabolism disruption, which is primarily manifested in the plasma lipids main classes ratio violation. It is shown that the spectrum of lipid and phospholipid composition of blood plasma in patients with pulmonary tuberculosis differs significantly from the spectrum in healthy people. Antituberculous chemotherapy with bactericidal and bacteriostatic action comes with normalization of a number of lipid metabolism indicators such as free fatty acids, triglycerides, cholesterol esters and phosphatidylserine. However, such indicators as total phospholipids, free cholesterol and lysophospholipids show negative dynamics, which is probably caused by the antituberculous drug’s effect.

Background. The problem of studying lipid metabolism in patients with tuberculosis is of interest to scientists around the world. The purpose of the study - to investigate lipid profile in pulmonary tuberculosis patients with concurrent insulin resistance. Materials and methods. Forty-one patients with pulmonary tuberculosis were examined. Insulin resistance index (HOMA-IR), total cholesterol level (TC), triglycerides (TG) level, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, very-low-density lipoprotein (VLDL) cholesterol and atherogenic index (AI) were measured. Results. Group 1 - 26 patients with tuberculosis and insulin resistance (HOMA-IR ˃ 2.7); Group 2 – 15 patients with tuberculosis without insulin resistance (HOMA-IR ˂ 2.7). Group 1 patients had severe course of TB with fever, severe fatigue and weakness, profuse sweating, weight loss, cough and shortness of breath. Median TC indices differed at significant level (p = 0.012): group 1 - 4.82 mmol/l, group 2 - 4.25 mmol/l. TG level was higher in group 1 patients - 1.32 mmol/l than in group 2 patients - 1.28 mmol/l. LDL cholesterol values were higher in group 1 patients - 3.2 mmol/l vs 2.5 mmol/l in group 2. The AI was higher in group1 (p = 0.005): 3.9 units against 2.8 units in group 2 patients. Conclusions. Insulin resistance in pulmonary tuberculosis patients was associated with severe course of the disease, severe clinical manifestations and impaired external respiration. Pro-atherogenic disorders of lipid metabolism in pulmonary tuberculosis patients with concurrent insulin resistance can be considered as the degree of endogenous intoxication.

In Indonesia, the diagnosis of pulmonary tuberculosis relies primarily on an identification of acid-fast bacilli on sputum smears. However, microscopic device has several limitations. The sensitivity of microscopic examination is variable. The quality of smear microscopic results is heavily depend on the workload, and the skill of the technician’s reading the slide. TB antigen rapid test device (TB Ag) is fast, easy and does not either need skillness of the operator. The kit detects specific secreted antigen M.tuberculosis coded by: RD (Region of Difference) 1, RD2 and RD3. These RD1−3 were found deleted from BCG (Bacille Calmette-Guerine) vaccine strain. In the present study, the diagnostic value of TB Ag was assessed. Sputum samples were examined from 59 suspected tuberculosis patients and 22 non tuberculosis patients. The samples of the suspected tuberculosis patients were collected as three consecutive sputum specimens (spot, morning, spot). The total 199 specimens were examined by sputum smear microscopy and TB Ag. M.tuberculosis culture by using Lowenstein Jensen media, which was used as a gold standard. The sensitivity and specificity of microscopic sputum smear were 83.8% (95% CI: 70.0–89.4) and 96.3% (95% CI: 89.8–98.7), respectively. While, the sensitivity and specificity of TB Ag were 72.6% (95% CI: 63.9–79.9) and 90.9% (95% CI: 72.2–97.5), respectively. The concordance between microscopic sputum smear and TB Ag was 70.8%. TB Ag can be considered as a new diagnostic tool for the diagnosis of pulmonary tuberculosis, especially at the health services where there is no expert technician available for microscopic sputum smear examination.

The aim: To assess carbohydrate and lipid metabolic profiles of tuberculosis patients with bilateral injuries of the lungs and mycobacteria excretion. Materials and methods: Seventy two newly diagnosed pulmonary TB patients were examined. Group I – 17 newly diagnosed TB patients who had unilateral pulmonary lesions and had no mycobacteria excretion. Group II – 55 newly diagnosed TB patients who had bilateral pulmonary lesions and mycobacteria excretion. The control group included 20 healthy persons. Fasting insulin level, indices of lipidogram were measured, oral glucose tolerance test was performed. Statistical processing of the obtained results was carried out by analyzing the contingency tables using the StatisticaBasicAcademic 13 for Windows software package. Results: Tuberculosis patients develop insulin resistance – condition that is a precursor to developing type 2 diabetes and metabolic disorder of lipid exchange – dyslipidemia. Patients with bilateral pulmonary lesions and mycobacteria excretion have the most pronounced disorders of carbohydrate and lipid metabolism compared to patients with limited lesions of the lungs. Conclusions: We suppose that mycobacteria excretion and bilateral lesions of lungs may be the markers of the degree of carbohydrate and lipid metabolism disorders in patients with pulmonary tuberculosis.

Tuberculosis infection exhibits different forms, namely, pulmonary, extrapulmonary, and latent. Here, diagnostic markers based on the gene expression of cytokines and chemokines for differentiating between tuberculosis infection state(s) were identified. Gene expression of seven cytokines (Interferon gamma (IFN-γ), Interferon gamma-induced protein 10 (IP-10), Interleukin-2 receptor (IL-2R), C-X-C Motif Chemokine Ligand 9 (CXCL-9), Interleukin 10 (IL-10), Interleukin 4 (IL-4), and Tumor Necrosis Factor alpha (TNF-α)) in response to tuberculosis antigen was analyzed using real-time polymerase reaction. The sensitivity and specificity of relative quantification (2^-ΔΔCt) of mRNA expression were analyzed by constructing receiver operating characteristic curves and measuring the area under the curve (AUC) values. Combinations of cytokines were analyzed using the R statistical software package. IFN-γ, IP-10, IL2R, and CXCL-9 showed high expression in latent and active tuberculosis patients (p = 0.001), with a decrease in IL10 expression, and no statistical difference in IL-4 levels among all the groups (p = 0.999). IL-10 differentiated pulmonary tuberculosis patients from latent cases with an AUC of 0.731. IL10 combined with CXCL-9 distinguished pulmonary tuberculosis patients from extrapulmonary cases with a sensitivity, specificity, and accuracy of 85.7%, 73.9%, and 81.0%, respectively. IL-10 together with IP-10 and IL-4 differentiated pulmonary tuberculosis from latent cases with a sensitivity and specificity of 77.1% and 88.1%, respectively. Decision tree analysis demonstrated that IFN-γ IL-2R, and IL-4 can diagnose tuberculosis infection with a sensitivity, specificity, and accuracy of 89.7%, 96.1%, and 92.7%, respectively. A combination of gene expression of cytokines and chemokines might serve as an effective marker to differentiate tuberculosis infection state(s).

Spleen Deficiency Syndrome

Hyperlipidemia is a common disease caused by abnormal plasma lipid metabolism. Lipidomics is a powerful and efficient technology to study the integration of disease and syndrome of Chinese medicine. This study investigated specific changes in lipid metabolites from hyperlipidemia patients with syndrome of liver qi-stagnation and spleen-deficiency (SLQSD). Lipid profiles in plasma samples from 29 hyperlipidemia patients including 10 SLQSD and 19 non-SLQSD and 26 healthy volunteers (NC) were tested by UPLC-QTOF/MS. PLS-DA analysis and database searching were performed to discover differentiating metabolites. Differences in lipid metabolites between hyperlipidemia and healthy people mainly include phosphatidylcholines, phosphatidylethanolamines, phosphatidylglycerols, and ceramides. Hyperlipidemia patients with SLQSD and non-SLQSD could be differentiated by using identified lipid metabolites including phosphatidylcholines, phosphatidylethanolamines, phosphatidylinositols, triglycerides, diacylglycerols, lysophosphatidylethanolamines, sphingomyelins, lysophosphatidylcholines, and lactosylceramides. There were significant differences of lipid metabolism between between different syndromes of the same disease such as hyperlipidemia which showed significant differences between SLQSD and non-SLQSD.

Pulmonary tuberculosis is a major health problem in Bangladesh that is responsible for about 7% of total death in a year. This study was conducted to isolate and identify Mycobacterium tuberculosis from sputum and to evaluate the efficacy of PCR as a modern diagnostic tool, for diagnosis of pulmonary tuberculosis, especially in the smear negative cases. One hundred and fifty suspected pulmonary TB patients (male/ female: 97/53) were included in this study. Single morning sputum was collected from each patient and diagnostic potential of PCR was compared with staining and culture. Twenty five (16.7%) sputum were positive by ZN stained smear. Among 125 smear negative samples, 13 (10.4%) yielded growth in culture in LJ media and 21 (16.8%) samples were positive by PCR. The sensitivity and specificity of PCR in smear negative cases was 100% and 92.9% respectively. Mean detection time in PCR was 24 hours. PCR detected M. tuberculosis in 21 smear negative and 9 culture negative samples. For diagnosis of tuberculosis in smear negative cases, PCR directly from sputum was a very sensitive and accurate method. In conclusion, PCR may be done, especially in clinically suspected pulmonary tuberculosis patients who remain negative by conventional methods.DOI: http://dx.doi.org/10.3329/bjmm.v6i2.19368 Bangladesh J Med Microbiol 2012; 06(02): 2-6

Pulmonary tuberculosis (TB) is a chronic disease that can bring about the sufferer's self-stigma and also affect his quality of life. A number of studies report that living with TB has a negative influence on the quality of life of sufferers even with or without self-stigma. The purpose of this study was to identify the quality of life of TB patients who experienced self-stigma. This research is a descriptive study, sample were 31 pulmonary TB patients. Data was collected using a questionnaire. Data analyzed by using frequency distribution and percentage. The researcher first screened TB patients who experienced self-stigma. The results showed that 25 people (80.64%) respondents experienced mild self-stigma. A total of 9 respondents (36%) had a quality of life score in the good category and as many as 16 respondents (64%) had enough category with an average quality of life score is 56.57. While respondents who had moderate self-stigma were 6 people (19.36%) with a good quality of life score was 1 person (16.67%) and enough category quality of life score were 5 people (83.33%) with an average quality of life score is 49.92.
