Krishnamoorthy Y, C S, Govindan D. Sex-based differences in TB treatment compliance: A mediating factor for sputum conversion among newly diagnosed pulmonary TB patients in Chennai, South India. Heliyon 2024; 10:e31185. [PMID: 38803852 PMCID: PMC11128919 DOI: 10.1016/j.heliyon.2024.e31185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 05/09/2024] [Accepted: 05/12/2024] [Indexed: 05/29/2024] Open
Abstract
Background Tuberculosis (TB) remains a global health concern, particularly in India, which carries a significant portion of the global burden. The role of sex as a determinant of health is increasingly recognized, impacting various aspects of TB, including treatment compliance and outcomes. This study aimed to determine the mediating role of treatment compliance in the relationship between sex and sputum conversion in newly diagnosed pulmonary TB patients in Chennai, South India. Methods We conducted a retrospective cohort study among patients newly diagnosed for TB at ESIC Medical College & PGIMSR between April 2020 and April 2022. A causal mediation analysis was performed to identify the direct and indirect effects of sex on sputum conversion via the mediator, treatment compliance. We employed logistic regression models and the "paramed" package for the analysis, with bootstrapping technique for examining the significance of indirect and direct effects. Results The Marginal Total Effect (MTE) suggested that females were more likely to have sputum positivity compared to males (OR: 6.77; p = 0.003). Direct effect of being female increased the odds of sputum positivity at the end of the intensive phase (OR: 3.42; p = 0.03). The indirect effect of being female via treatment compliance significantly increased the odds of sputum positivity at the end of the intensive phase (OR: 1.98; p = 0.03). Conclusion The study provides evidence that treatment compliance significantly mediates the relationship between sex and sputum conversion in TB patients, highlighting the necessity to consider gendered dimensions of health in TB control strategies.

Wang T, Zhou C, Shang L, Zhou X. Comorbidity and drug resistance of smear-positive pulmonary tuberculosis patients in the yi autonomous prefecture of China: a cross-sectional study. BMC Infect Dis 2023; 23:586. [PMID: 37674123 PMCID: PMC10483793 DOI: 10.1186/s12879-023-08568-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 08/27/2023] [Indexed: 09/08/2023] Open
Abstract
BACKGROUND Tuberculosis (TB) has a high morbidity and mortality rate, and its prevention and treatment focus is on impoverished areas. The Liangshan Yi Autonomous Prefecture is a typical impoverished area in western China with insufficient medical resources and high HIV positivity. However, there have been few reports of TB and drug resistance in this area. METHODS We collected the demographic and clinical data of inpatients with sputum smear positive TB between 2015 and 2021 in an infectious disease hospital in the Liangshan Yi Autonomous Prefecture. Descriptive analyses were used for the epidemiological data. The chi-square test was used to compare categorical variables between the drug-resistant and drug-susceptible groups, and binary logistic regression was used to analyse meaningful variables. RESULTS We included 2263 patients, 79.9% of whom were Yi patients. The proportions of HIV (14.4%) and smoking (37.3%) were higher than previously reported. The incidence of extrapulmonary TB (28.5%) was high, and the infection site was different from that reported previously. When drug resistance gene detection was introduced, the proportion of drug-resistant patients became 10.9%. Patients aged 15-44 years (OR 1.817; 95% CI 1.162-2.840; P < 0.01) and 45-59 years (OR 2.175; 95% CI 1.335-3.543; P < 0.01) had significantly higher incidences of drug resistance than children and the elderly. Patients with a cough of ≥ 2 weeks had a significantly higher chance of drug resistance than those with < 2 weeks or no cough symptoms (OR 2.069; 95% CI 1.234-3.469; P < 0.01). Alcoholism (OR 1.741; 95% CI 1.107-2.736; P < 0.05) and high bacterial counts on sputum acid-fast smears (OR 1.846; 95% CI 1.115-3.058; P < 0.05) were significant in the univariate analysis. CONCLUSIONS Sputum smear-positive TB predominated in Yi men (15-44 years) with high smoking, alcoholism, and HIV rates. Extrapulmonary TB, especially abdominal TB, prevailed. Recent drug resistance testing revealed higher rates in 15-59 age group and ≥ 2 weeks cough duration. Alcohol abuse and high sputum AFB counts correlated with drug resistance. Strengthen screening and supervision to curb TB transmission and drug-resistant cases in the region.

Comparative serum lipid and immunohematological values among adult pulmonary tuberculosis and tuberculosis lymphadenitis cases and their association with sputum bacilli load and time to culture positivity in Northwestern Ethiopia. Lipids Health Dis 2023; 22:56. [PMID: 37106418 PMCID: PMC10134535 DOI: 10.1186/s12944-023-01821-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Accepted: 04/21/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND The serum lipid and immunohematological values of tuberculosis lymphadenitis (TBLN) patients is poorly documented relative to pulmonary tuberculosis (PTB) cases. Therefore, the aim of this study was to investigate the serum lipid and immunohematological values of patients with TBLN in comparison with PTB (PTB) patients. METHODS An institution-based comparative cross-sectional study was conducted in Northwest Ethiopia from March to December 2021. The study participants were bacteriologically confirmed PTB (n = 82) and TBLN (n = 94) cases with no known comorbidity and whose ages was greater than 18 years and with no current pregnancy. Independent sample t-test, one-way ANOVA, box plot, and correlation matrix were used to analyze the data. RESULTS The body mass index (BMI), CD4 + T cell count, and high-density lipoprotein-Cholesterol (HDL-C) values were significantly higher among TBLN cases compared with PTB cases. Additionally, the total white blood cell (WBC) count, hemoglobin (Hb), total Cholesterol (CHO) and creatinine (Cr) values were relatively higher among TBLN than PTB (P > 0.05). On the reverse, the platelet count and triacylglycerol (TAG) values were relatively higher among PTB than in TBLN cases. While the mean days of culture positivity were 11.6 days for TBLN, the mean days of culture positivity were 14.0 days for PTB. Anemia and serum lipid values showed no correlation with sputum bacilli load and time to culture positivity. CONCLUSION Tuberculous lymphadenitis patients were well-endowed with serum lipid, immunological and nutritional status compared with PTB cases. Hence, the high incidence rate of TBLN in Ethiopia could not be explained by low peripheral immunohematological values, malnutrition, Anemia, and dyslipidemia. Further study for identifying the predictors for TBLN in Ethiopia is highly desirable.

Missed Tuberculosis Investigations and Associated Factors in Patients with Symptoms Indicative of Tuberculosis at Public Health Institutions in Northwest Ethiopia: The Application of a Negative Binomial Model. Infect Drug Resist 2022; 15:1947-1956. [PMID: 35469307 PMCID: PMC9034845 DOI: 10.2147/idr.s355247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Accepted: 03/26/2022] [Indexed: 11/23/2022] Open
Abstract
Background Tuberculosis (TB) remains one of the top health problems in Ethiopia, and over one-third of estimated TB cases remain undetected. This study examined the magnitude and factors of missed opportunities for TB investigation at public health facilities in Northwest Ethiopia. Methods A facility-based cross-sectional study was conducted among 412 adult patients with TB symptoms from 34 randomly selected public health facilities. Data on socio-demographics, TB symptoms, and clinical status were collected by an exit interview. A patient was considered missed for TB investigation if he/she had at least one symptom suggestive of TB but did not receive a sputum smear and/or x-ray evaluation to rule out TB. We computed descriptive and analytical statistics using SPSS version 26. A negative binomial regression analysis was used to identify factors associated with missed opportunities for TB investigation. Statistical significance was determined at a p-value less than 0.05. Results A total of 412 presumptive TB patients, 235 (57%) females and 247 (60%) rural dwellers were interviewed. The mean age of respondents was 35 ± 8 years and 228 (55.3%) were from health centers. Over two-thirds, 284 (69%) were new patients, 62 (15%) were HIV positive and 78 (19%) had diabetes mellitus (DM). Fifty patients with symptoms suggestive of TB did not receive sputum evaluation services. Inability to read and write, having DM, having normal body mass index and facility type they visited were significant factors to missing opportunities to get TB investigations. Conclusion A significant number of patients with symptoms suggestive of TB were missed for sputum evaluation to rule out TB. Education level, comorbidity, nutritional status and type of facility patients attended were factors of missing opportunities for TB investigation. Thus, improving quality of TB diagnosis, screening TB among all types of patients, and paying attention to screen illiterate people are crucial to avoid missing potential TB cases.

Abstract
ABSTRACT Objectives: to analyze government social initiatives aimed at people with tuberculosis and the possibilities of access to government social programs and income transfers through the perception of tuberculosis program managers. Methods: descriptive, qualitative study with 19 managers from Belém, Recife, Campo Grande, and Rio de Janeiro, Brazil. Thematic content analysis was used. Results: there is no specific government social support for people with tuberculosis; the benefits are intended for people in social vulnerability. There are partnerships between the institutions of the secondary social healthcare network, social assistance, and community institutions. Final Considerations: the support of official bodies is important for the control of tuberculosis; however, the profile of people’s vulnerability is a determining factor for access to/destination of resources from these government social support programs.

Abstract
Resumo Objetivo Analisar as percepções de enfermeiros sobre gestão do cuidado e seus fatores intervenientes para o controle da tuberculose na Atenção Primária em Saúde. Método Estudo descritivo, qualitativo, realizado com 29 enfermeiros que atuavam no controle da tuberculose em 23 Unidades Básicas de Saúde de Belém, Pará. Os dados foram produzidos por entrevistas individuais, utilizando roteiro semiestruturado, e submetidos à análise de conteúdo temática, proposta por Bardin. Resultados Originaram-se duas categorias temáticas: “A gestão do cuidado de enfermeiros para o controle da tuberculose nas Unidades Básicas de Saúde” e “Fatores intervenientes na efetivação da gestão do cuidado no controle da tuberculose nas Unidades Básicas de Saúde”. Conclusão e implicações para a prática O conhecimento dos enfermeiros sobre a política e a gestão do cuidado no controle da tuberculose precisa ser fortalecido, e embora eles tenham clareza sobre suas competências, não conseguem realizá-las em sua plenitude por questões referentes à pouca organização dos serviços, centralização das atividades nos enfermeiros, baixa cooperação multiprofissional, falta de insumos e de pessoal e questões socioeconômicas ligadas ao usuário com tuberculose.

Abstract
Objectives There is limited published literature on the genetic risks of chronic inflammatory related disease (eg, obesity and cardiovascular disease) among the Central Asia population. The aim is to determine potential genetic loci as risk factors for obesity for the Kazakhstani population. Setting Kazakhstan. Participants One hundred and sixty-three Kazakhstani nationals (ethnic groups: both Russians and Kazakhs) were recruited for the cross-sectional study. Linear regression models, adjusted for confounding factors, were used to examine the genetic associations of single nucleotide polymorphisms (SNPs) in 19 genetic loci with obesity (73 obese/overweight individuals and 90 controls). Results Overall, logistic regression analyses revealed genotypes C/T in CRP (rs1205), A/C in AGTR1 (rs5186), A/G in CBS (rs234706), G/G in FUT2 (rs602662), A/G in PAI-1 (rs1799889), G/T (rs1801131) and A/G (rs1801133) in MTHFR genes significantly decrease risk of overweight/obesity. After stratification for ethnicity, rs234706 was significantly associated with overweight/obesity in both Russians and Kazakhs, while rs1800871 was significant in Kazakhs only. Conclusions This study revealed that variations in SNPs known to be associated with cardiovascular health can also contribute to the risks of developing obesity in the population of Kazakhstan.

Abstract
Smear-positive pulmonary tuberculosis (PTB) is more infectious compared to smear-negative PTB and have great significance for epidemiology and infection control. The prevalence of smear-positive PTB rarely affects males and females equally. Hence, we aimed to identify the sex-related differences in the prevalence of smear-positive PTB and its associated factors in Kuala Lumpur, Malaysia. A cross-sectional study was conducted using data from the National Tuberculosis Information System (TBIS) from 1 January, 2015, to 31 December, 2019. The study population was selected using simple random sampling from the list of registered PTB patients in TBIS. The criteria for inclusion were all Malaysian adults aged ≥18 years residing in Kuala Lumpur and registered as PTB in TBIS. Factors associated with smear-positive PTB in male and female patients were determined using multiple logistic regression analysis. Overall prevalence of smear-positive PTB was 68.6%, and male patients predominated (71%). The male:female prevalence ratio of smear-positive PTB was 2.4:1. Male patients who worked as machine operators and elementary workers (adjusted odds ratio (aOR) 2.23, 95% confidence interval (CI) 1.24-4.02, p = 0.007), were self-employed (aOR 2.58, 95% CI 1.46-4.56, p = 0.001), lived in a residence categorized as 'other' (aOR 2.49, 95% CI 1.28-4.86, p = 0.007) and were smokers (aOR 1.37, 95% CI 1.01-1.87, p = 0.045) had higher odds for smear-positive PTB. Meanwhile, female patients with diabetes mellitus had higher odds for smear-positive PTB (aOR 1.92, 95% CI 1.05-3.54, p = 0.035), while female patients who were healthcare workers had lower odds (aOR 0.33, 95% CI 0.12, 0.94, p = 0.039). The prevalence of smear-positive PTB is higher in males compared to females. The factors associated with smear-positive PTB differed based on sex. The current TB control program, especially on smear-positive PTB, should likely be strategized and stratified by sex.

Abstract
Lung cavitation is the classic hallmark of TB, which facilitates the disease development and transmission. It involves the degradation of lung parenchyma which is mainly made up of collagen fibers by metalloproteinases (MMPs) produced by activated monocyte-derived cells, neutrophils and stromal cells. The following population-based preliminary case-control study of adults with TB (50) and controls (112) without TB was used to investigate possible association between rs1800012 in COL1A1, rs12722 in COL5A1 genes and pulmonary TB in Kazakhstan. We examined 162 samples (50 cases and 112 controls) to study the associations between TB disease status and demographic variables along with single nucleotide polymorphisms related to COLA1 and COL5A1. The unadjusted χ2 and multivariable logistic regression was performed to find out relationships between SNP and other predictors. Preliminary findings suggest that there is a statistically significant association of age (AOR = 0.97, 95% CI:0.94-0.99, p value = 0.049), social status (AOR = 2.41, 95% CI:1.16-5.02, p value = 0.018), HIV status (AOR = 7.12, 95% CI:1.90-26.7, p value = 0.004) and heterozygous rs12722 SNP (AOR = 2.47, 95% CI:1.17-5.19, p value = 0.018) polymorphism of COL5A1 gene with TB susceptibility. The association of collagen genes with TB pathogenesis indicates that anti TB programs can include development of new drug regimens that include MMP inhibitors which has been found to be helpful in collagen remodeling and repair. Therapeutic targeting of MMPs will prevent extracellular matrix and collagen degradation and granuloma maturation.

Abstract
BACKGROUND Ambulatory based treatment of tuberculosis has been recently introduced in Kazakhstan. We sought to assess the attitudes of the general population, TB patients and their household members towards ambulatory TB treatment and identify how knowledge of TB is associated with these attitudes. METHODS New pulmonary TB cases and their household and community controls were recruited from three regions of Kazakhstan in 2012-2014. 1083 participants completed audio computer-assisted self interviews to assess their knowledge of TB and attitudes towards ambulatory care. Mixed effects logistic regression models were used to identify factors associated with attitudes toward ambulatory TB treatment. RESULTS The proportion of people who considered ambulatory TB treatment as appropriate was very low (24.9%). Positive attitudes towards ambulatory TB treatment were significantly associated with region of residence, higher level of education, family support and experience with TB. The association between sufficient tuberculosis knowledge and favorable attitude toward ambulatory treatment was stronger among community controls compared to TB patients and their family members. CONCLUSIONS This study provides insight into attitudes toward ambulatory TB treatment among different groups and the specific influence of TB knowledge on these attitudes. Our findings can inform the process of integration of new TB treatment strategies and the development of appropriate education and advocacy programs in the general population.

Abstract
PURPOSE OF REVIEW The tide of HIV, hepatitis C virus (HCV) and drug-resistant tuberculosis (TB) is a challenge for the penitentiary system in Eastern Europe Central Asia (EECA) region. We have analyzed the existing services for incarcerated individuals with HIV, HCV and TB to assess the current situation in the EECA region. RECENT FINDINGS Because of the current criminal-legal system, key risk population with strong linkage to the blood-borne and airborne infections has a high proportion among prisoners. Management of these diseases includes a set of services, such as early detection, counseling, testing and treatment, prevention, harm reduction programme, wide educational and information efforts, and organization of continuity care after release. WHO has developed a set of targets, the only precise achievement of which will reduce the burden of these infections and eliminate them as a public health problem. SUMMARY It is necessary to closely monitor the delivery of HIV, HCV and TB care services in penitentiary system of the EECA countries. The comprehensive operational research will help to develop the most effective practices allowing to achieve the care provision for the entire contingent of the penitentiary system and its continuity in the civil sector. Sustainable and sufficient funding is required as well as enough attention to ensure healthcare services at an appropriate level in the penitentiary system.

Comorbidities between tuberculosis and common mental disorders: a scoping review of epidemiological patterns and person-centred care interventions from low-to-middle income and BRICS countries. Infect Dis Poverty 2020; 9:4. [PMID: 31941551 PMCID: PMC6964032 DOI: 10.1186/s40249-019-0619-4] [Citation(s) in RCA: 36] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 12/23/2019] [Indexed: 12/22/2022] Open
Abstract
Background There is increasing evidence that the substantial global burden of disease for tuberculosis unfolds in concert with dimensions of common mental disorders. Person-centred care holds much promise to ameliorate these comorbidities in low-to-middle income countries (LMICs) and emerging economies. Towards this end, this paper aims to review 1) the nature and extent of tuberculosis and common mental disorder comorbidity and 2) person-centred tuberculosis care in low-to-middle income countries and emerging economies. Main text A scoping review of 100 articles was conducted of English-language studies published from 2000 to 2019 in peer-reviewed and grey literature, using established guidelines, for each of the study objectives. Four broad tuberculosis/mental disorder comorbidities were described in the literature, namely alcohol use and tuberculosis, depression and tuberculosis, anxiety and tuberculosis, and general mental health and tuberculosis. Rates of comorbidity varied widely across countries for depression, anxiety, alcohol use and general mental health. Alcohol use and tuberculosis were significantly related, especially in the context of poverty. The initial tuberculosis diagnostic episode had substantial socio-psychological effects on service users. While men tended to report higher rates of alcohol use and treatment default, women in general had worse mental health outcomes. Older age and a history of mental illness were also associated with pronounced tuberculosis and mental disorder comorbidity. Person-centred tuberculosis care interventions were almost absent, with only one study from Nepal identified. Conclusions There is an emerging body of evidence describing the nature and extent of tuberculosis and mental disorders comorbidity in low-to-middle income countries. Despite the potential of person-centred interventions, evidence is limited. This review highlights a pronounced need to address psychosocial comorbidities with tuberculosis in LMICs, where models of person-centred tuberculosis care in routine care platforms may yield promising outcomes.

Abstract
Tuberculosis (TB) poses an important health challenge and a significant economic burden for Kazakhstan and in Central Asia. Recent findings show a number of immunological related processes and host Mycobacterium tuberculosis defense are impacted by a variety of genes of the human host including those that play a part in the vitamin D metabolism. We investigated the genetic variation of genes in the vitamin D metabolic pathway of a cohort 50 TB cases in Kazakhstan and compared them to 34 controls living in the same household with someone infected with TB. We specifically analyzed 11 SNPs belonging to the following genes: DHCR7, CYP2R1, GC-1, CYP24A1, CYP27A1, CYP27B1, VDR and TNFα. These genes play a number of different roles including synthesis, activation, delivery and binding of the activated vitamin D. Our preliminary results indicate significant association of VDR (vitamin D receptor) SNPs (rs1544410, BsmI, with OR = 0.425, CI 0.221-0.816, p = 0.009 and rs731236, TaqI with OR = 0.443, CI 0.228-0.859, p = 0.015) and CYP24A1 (rs6013897 with OR = 0.436, CI 0.191-0.996, p = 0.045) with TB. Interaction of genetic variation of VDR and CYP24A1 may impact susceptibility to TB. The findings provided initial clues to understand individual genetic differences in relation to susceptibility and protection to TB.

Abstract
Tuberculosis continues to be a major public health problem. Although efforts to control the epidemic have reduced mortality and incidence, there are several predisposing factors that should be modified in order to reduce the burden of the disease. This review article will address some of the risk factors associated with tuberculosis infection and active tuberculosis, including diabetes, smoking, alcohol use, and the use of other drugs, all of which can also contribute to poor tuberculosis treatment results. Tuberculosis can also lead to complications in the course and management of other diseases, such as diabetes. It is therefore important to identify these comorbidities in tuberculosis patients in order to ensure adequate management of both conditions.

Abstract
OBJECTIVE To estimate the prevalence of self-reported tuberculosis TB diagnosed at Peruvian correctional facilities (CFs), and their associated factors. METHODS Cross-sectional study based on secondary analysis of the National Census held in all Peruvian CFs in 2016. Outcome was defined as self-reported TB diagnosed by a healthcare professional intra-penitentiary. A descriptive bivariate analysis was carried out, followed by multivariate analysis using Poisson regression in order to calculate the adjusted prevalence ratios (PRa). Additionally, a mixed effects multilevel model adjusted by CFs as clusters was performed. RESULTS Of 77 086 prison inmates in 66 CFs participated in the original census, of which 69 890 were included. Of these, 1754 self-reported TB diagnosed intra-penitentiary, yielding a prevalence of 2510/100 000 PDL. In the final model, self-reported TB was associated with younger age, male gender, lower educational level, not having a stable partner, having prison readmissions and having relatives in prison. There was also strong association with HIV/AIDS (PRa 2.77; 1.84-4.18), STIs (PRa 2.13; 1.46-3.10), DM (PRa 1.99; 1.59-2.50) and recreational drugs use (PRa 1.41; 1.23-1.61). The mixed model showed significant variance for belonging to different CFs (2.13; 1.02-4.44) and CF overcrowding (3.25; 1.37-7.71). CONCLUSIONS Self-reported TB prevalence found was higher than reported by other lower/lower-middle income countries. Demographic factors, individual clinical features and overcrowding increases the likelihood of self-reported TB.

Immunonutritional status and pulmonary cavitation in patients with tuberculosis: A revisit with an assessment of neutrophil/lymphocyte ratio. Respir Investig 2018; 57:60-66. [PMID: 30528689 DOI: 10.1016/j.resinv.2018.08.007] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2018] [Revised: 08/06/2018] [Accepted: 08/16/2018] [Indexed: 11/28/2022]
Abstract
BACKGROUND Several reports have described the importance of immunological and nutritional factors in the morbidity and/or mortality of patients with tuberculosis. The aim of this study was to evaluate the association between pulmonary cavitation and immunonutritional status, assessed by parameters such as neutrophil/lymphocyte ratio (NLR) and prognostic nutritional index (PNI), in patients with pulmonary tuberculosis. METHODS We retrospectively analyzed the data of 137 patients with culture-positive active pulmonary tuberculosis without bacterial pneumonia diagnosed at Kainan Hospital between April 2008 and March 2016. The associations between the levels of serum albumin, lymphocytes, NLR, PNI, platelet to lymphocyte ratio (PLR), and body mass index (BMI) and pulmonary cavitation were evaluated in the patients. RESULTS A total of 83 men and 63 women (median age, 75 years; range, 16-94 years) were included in the study. Sixty-six patients had smoking history; 55 patients had respiratory symptoms, while 44 patients did not have any symptoms. Patient׳s delay, defined as medical examination performed over 60 days after the onset of symptoms was observed in 25 patients. Univariate analysis showed that high NLR (≥ 5), high PLR (≥200), low serum albumin (<3 g/dL), high neutrophil count (≥6000/mm3), and low lymphocyte count (<1000/mm3) were associated with pulmonary cavitation. Multivariate analysis showed that high NLR and low serum albumin were associated with pulmonary cavitation. CONCLUSION Malnutrition and increased severity of inflammation may be associated with pulmonary cavitation in patients with tuberculosis. Further studies are warranted to confirm the findings of the present study.

Hemostasis and Lipoprotein Indices Signify Exacerbated Lung Injury in TB With Diabetes Comorbidity. Chest 2017; 153:1187-1200.

Abstract
BACKGROUND Exacerbated immunopathology is a frequent consequence of TB that is complicated by diabetes mellitus (DM); however, the underlying mechanisms are still poorly defined. METHODS In the two groups of age- and sex-matched patients with TB and DM (DM-TB) and with TB and without DM, we microscopically evaluated the areas of caseous necrosis and graded the extent of perinecrotic fibrosis in lung biopsies from the sputum smear-negative (SN) patients. We scored acid-fast bacilli in sputum smear-positive (SP) patients and compiled CT scan data from both the SN and SP patients. We compared inflammatory biomarkers and routine hematologic and biochemical parameters. Binary logistic regression analyses were applied to define the indices associated with the extent of lung injury. RESULTS Enlarged caseous necrotic areas with exacerbated fibrotic encapsulations were found in SN patients with DM-TB, consistent with the higher ratio of thick-walled cavities and more bacilli in the sputum from SP patients with DM-TB. Larger necrotic foci were detected in men compared with women within the SN TB groups. Significantly higher fibrinogen and lower high-density lipoprotein cholesterol (HDL-C) were observed in SN patients with DM-TB. Regression analyses revealed that diabetes, activation of the coagulation pathway (shown by increased platelet distribution width, decreased mean platelet volume, and shortened prothrombin time), and dyslipidemia (shown by decreased low-density lipoprotein cholesterol, HDL-C, and apolipoprotein A) are risk factors for severe lung lesions in both SN and SP patients with TB. CONCLUSIONS Hemostasis and dyslipidemia are associated with granuloma necrosis and fibroplasia leading to exacerbated lung damage in TB, especially in patients with DM-TB.

Abstract
BACKGROUND AND OBJECTIVES As for all tests, the diagnostic performances of Xpert MTB/RIF might be different in settings with different tuberculosis prevalence. Aim of the study is to evaluate the performances of Xpert MTB/RIF to diagnose tuberculosis in Brazil, where 407 culture-confirmed tuberculosis patients were retrospectively enrolled in Rio Grande do Sul, between 2015 and 2016. METHODS Sensitivity, specificity, positive and negative predictive values of the test were calculated and a logistic regression analysis was performed to assess the role played by explanatory variables in the occurrence of true positive and negative diagnostic results. RESULTS Sensitivity of Xpert MTB/RIF was 100.0%, specificity 92.8%; positive and negative predictive values were 71.4% and 100.0%, respectively. In the HIV- infected sub-group specificity was 59.3%. In the multivariate logistic regression analysis, true positivity was associated with increasing age (1.0; p-value: 0.02) while true positivity and negativity were negatively associated with alcohol abuse. CONCLUSIONS Xpert is sensitive and specific in the Brasilian settings.
