Diagn Microbiol Infect Dis 2024; 110:116469. [PMID: 39106650 DOI: 10.1016/j.diagmicrobio.2024.116469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 05/20/2024] [Accepted: 07/24/2024] [Indexed: 08/09/2024]
Abstract
Failure in recognizing non-tuberculous mycobacteria (NTM) leads to misdiagnosis of multidrug-resistant Mycobacterium tuberculosis Complex (MTBC). There is an unmet need for diagnostic tools that can differentiate between NTMs and MTBC, and that are affordable for Low- and Middle-income Countries (LMIC). Earlier we developed a strip-based CrfA assay technology to detect the Carbapenem Resistance Factor A (CrfA) enzyme present only in MTBC. However, the strip-based CrfA assay had low turnaround time and lacked high-throughput capabilities. In this current research, we have developed a 96well-formatted CrfA assay for high-throughput detection of MTBC and differentiation with NTMs. This 96well-formatted CrfA assay displays a low turnaround time of 6-8 h with 100 % specificity and 93.75 % sensitivity on clinical samples. Based on these attributes, this 96well-formatted assay represents a valuable complementary tool to mitigate the misdiagnosis of chronic pulmonary tuberculosis with non-tuberculous mycobacteria in poorer nations.

Abstract
Objective This study aimed to investigate the impact of diabetes mellitus (DM) on tuberculosis (TB) treatment response using bacterial clearance as a surrogate marker. Method We compared smear microscopy, culture, and tuberculosis molecular bacterial load assay (TB-MBLA) for treatment monitoring. Following that, bacterial clearance was longitudinally monitored among TB-only (TB without DM) and TB-diabetes (TBDM) patients using TB-MBLA. Results Ninety-three participants, including 59 TB-only and 34 TBDM patients, were enrolled. TB-only patients exhibited higher upper zone infiltrations (32/35 vs 16/22, p = 0.059) suggesting a trend towards significance, and significantly more cavitation in the same zone (16/18 vs 7/13, p = 0.028). There was a high proportion of Mycobacterium africanum (Maf) among the TBDM cohort (p = 0.0044).At baseline, TB-only patients exhibited a higher average bacterial burden (4.49 logeCFU/mL) compared to the TBDM group (3.91 logeCFU/mL) (p = 0.042). The bacterial load in the TB-only group decreased significantly during treatment but the TBDM group experienced delayed clearance throughout the intensive phase of anti-TB treatment even at day 56 (p = 0.028). The TB-only group demonstrated a shorter median time to TB-MBLA conversion to negative (57 days) compared to the TBDM group (62 days) (p = 0.022). Conclusion These findings underscore the urgent call for understanding the interplay between diabetes and TB, emphasizing the need for tailored interventions in optimizing TB care for individuals comorbid with diabetes.

Abstract
Introduction Pulmonary tuberculosis (PTB) remains a significant health concern, particularly in individuals infected with human immunodeficiency virus (HIV) who are more susceptible to developing active TB disease. Early and accurate diagnosis of TB is crucial for effective treatment and prevention of transmission. This study aims to evaluate the potential of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOFMS) analysis of bronchoalveolar lavage fluid (BALF) for diagnosis of suspected PTB in HIV-infected patients. Methods This retrospective study recruited 60 HIV-infected patients with suspected PTB presenting with respiratory symptoms and abnormal chest radiographs between January 2022 and June 2023. BALF samples were collected and subjected to analysis using MALDI-TOF MS, GeneXpert, acid-fast bacilli (AFB) smear and culture. And their diagnostic performance was compared. Results The sensitivity of MALDI⁃TOFMS for diagnosing PTB was 83.3 %, which was better than that of smear 11.9 %, culture 40.5 % or Xpert38.1 % (all p < 0.01). The area under the curve (AUC) value of MALDI⁃TOFMS was 0.889, which was better than that of smear 0.532, culture 0.675 or Xpert 0.690 (all p < 0.01). The katG315 and rpoB-RRDR 511 mutations were detected by the MALDI⁃TOFMS in two patients. Conclusion Nucleotide MALDI-TOFMS has a good clinical performance for rapid diagnosis of PTB from BALF samples in HIV infected patients, and detects mutations of TB simultaneously.

Abstract
INTRODUCTION Diagnosing peritoneal tuberculosis is challenging due to unspecific clinical manifestations, particularly in immunocompromised patients with HIV/AIDS and tuberculosis infections. PRESENTATION OF CASE An Indonesian man, 26-years-old, complained of mid-abdominal colic and constipation. The patient's present state exhibited symptoms of weakness and paleness, oral candidiasis, a bloated abdomen, palpable discomfort, and shifting dullness. The ascitic fluid analysis showed increased ADA (709 U/L), and detected Mycobacterium tuberculosis using GeneXpert MTB/RIF. Radiographic examination from abdominal x-ray and CT scan revealed a small bowel obstruction. He received intestinal decompression, pain control, intravenous fluid resuscitation, and correction of electrolyte imbalance for small bowel obstruction without any indication for surgical intervention. He also receive first-line ATD for 2 months during intensive phase and 4 months for continuous phase. After a period of 2 weeks following the ATD administration, the patient began taking ARV medication on a daily basis. He showed a good prognosis 6 months following. DISCUSSION The diagnosis of peritoneal tuberculosis is challenging due to its unspecific manifestation and some cases are identified when complications such as small bowel obstruction appear. The ADA test and GenExpert MTB/RIF are useful instruments for promptly diagnosing tuberculosis. It is suggested to use ARV treatment in individuals with HIV/AIDS who have peritoneal tuberculosis, starting 2 weeks following ATD treatments. CONCLUSION Peritoneal tuberculosis with small bowel obstruction and HIV/AIDS infection is a rare case in which early diagnosis and monitoring play an important role in successful treatment.

Abstract
Mycobacterium tuberculosis causes a chronic infectious disease called tuberculosis. Phylogenetic lineage 2 (L2) of M. tuberculosis, also known as the East Asian lineage, is associated with high virulence, increased transmissibility, and the spread of multidrug-resistant strains. This review article examines the genomic characteristics of the M. tuberculosis genome and M. tuberculosis lineage 2, such as the unique insertion sequence and spoligotype patterns, as well as MIRU-VNTR typing, and SNP-based barcoding. The review describes the geographical distribution of lineage 2 and its history of origin. In addition, the article discusses recent studies on drug resistance and compensatory mechanisms of M. tuberculosis lineage 2 and its impact on the pathogen's transmissibility and virulence. This review article discusses the importance of establishing a unified classification for lineage 2 to ensure consistency in terminology and criteria across different studies and settings.

Abstract
Objectives This study examined the prevalence and sociodemographic factors among older adults with HIV and TB status in South Africa. Methods This data was cross-sectional and obtained from the 2019 General Household Surveys in South Africa. Adults 50 years and over with reported HIV and TB status were included (N = 9,180,047). We reported statistical analyses of the descriptive, Chi-square and Fisher's exact tests, and binary logistic regression. Results The study has found a prevalence rate of HIV to be 5.3% and TB to be 2.9% among older adults aged 50 years and above in South Africa. However, the study found HIV and TB to be highest among older adults residing in Gauteng, KwaZulu-Natal and Eastern Cape provinces. For HIV status, the female gender [AOR = 0.80*, CI 95% = 0.80-0.80] and secondary education [AOR = 0.57, CI 95% = 0.56-0.58] have lower odds of association among older adults with HIV. Regarding TB status, primary education [AOR = 1.08*, CI 95% = 1.06-1.10] and diabetes [AOR = 1.87*, CI 95% = 1.82-1.91] have lower likelihoods of associations among older adults with TB. Conclusion There is an urgent need to escalate scientific and political attention to address the HIV/TB burden in older adults and, public health policymakers need to take cognizance of the interdependence of inequality, mobility, and behavioural modification among this high-risk population.

Abstract
Background The co-occurrence of tuberculosis (TB) and AIDS (HIV) has emerged as a significant public health challenge. This study investigated the epidemiological factors and treatment outcomes of TB in individuals based on their HIV status in Iran. Methods The current study was a descriptive-analytical cross-sectional study that focused on new patients diagnosed with TB in Iran between 2018 and 2021. Patients' data were sourced from the National Tuberculosis Registry database of Iran. A multiple logistic regression model was used to investigate the relationship between the most important influencing factors and TB/HIV coinfection. Results Over a 4-year period, a study was conducted on 25,011 new TB patients out of 30,762 registered in the national database. TB and HIV were coinfected in 672 cases (2.68%). The highest number of coinfection cases were found in patients with smear-negative pulmonary tuberculosis (249 patients, 37.05%) and extrapulmonary tuberculosis (123 patients, 18.19%). TB patients with coinfection had a median TB treatment duration of three months longer than others. The success rate of TB treatment was lower in patients with coinfection (437 patients, 65.02%) than in non-coinfection patients (20,302 patients, 83.41%). Treatment success probability in smear-positive pulmonary tuberculosis patients with and without coinfection was lower than other types of TB. Logistic regression analysis showed that having a TB risk factor was the strongest predictor of coinfection, with an odds ratio of 29.73 (95% CI: 22.05-40.07), followed by having an HIV risk factor with an odds ratio of 17.52 (95% CI: 13.68-22.45). Conclusions The findings of this research offer significant insights into the potential causes of HIV coinfection in individuals with TB, which could be used to inform the development of policies and strategies aimed at enhancing the identification and treatment of TB patients who are at risk of TB/HIV coinfection and to promote optimal health status for patients with TB.

Abstract
Tuberculosis (TB) and acquired immunodeficiency syndrome (AIDS) are prevalent infectious diseases that continue to pose a significant global health burden. The co-infection of mycobacterium tuberculosis and human immunodeficiency virus (HIV) represents a substantial public health challenge, particularly in developing nations. In this study, we present an exceptional case of spinal tuberculosis complicated by HIV infection, which exhibited relapse post-surgery necessitating reoperation, along with the emergence of drug resistance. The first operation was lumbar lesion removal, decompression, internal fixation, and bone graft fusion assisted by lumbar discioscopy. The second operation was ultrasound-guided puncture and drainage of right psoas major abscess. The management of patients with HIV/TB co-infection demands specific considerations regarding medication regimens, surgical interventions, and nursing care. However, limited experience exists in treating such individuals, thus further research is imperative to enhance our understanding of HIV/TB co-infection.

Abstract
Objective: The objective of this study is to determine the drug resistance status of pulmonary tuberculosis patients in Jilin Province. Methods: A retrospective survey was conducted on 395 sputum culture TB-positive patients admitted to the tuberculosis hospital in Jilin Province in 2019. Sputum samples were cultured in acidic Roche medium. Drug sensitivity testing was conducted using the proportional method. Sensitivity was reported if the percentage of drug resistance was less than 1%, and resistance was reported if the percentage was ≥1%. Statistical analysis was performed using SPSS 22.0. Results: 395 tuberculosis patients with positive sputum tuberculosis culture were included in the study, with 102 being initially treated and 293 being retreated. The study population consisted of 283 males and 112 females. Sex, age, nationality, occupation, marital status, diabetes comorbidity, initial treatment, normal health status, BCG vaccine vaccination, smoking, and alcohol consumption were considered as factors that may affect the rate of multidrug resistance. And only the history of treatment (initial treatment) was associated with multidrug resistance (p = 0.032). This indicates that retreatment is the most significant risk factor for the occurrence of multidrug resistance in tuberculosis. The multidrug resistance rate in retreated patients is 3.764 times higher than that in initially treated patients. Conclusion: The prevalence of multidrug-resistant is higher in retreated patients compared to initially treated patients in the study population. Multidrug resistance is only associated with the treatment history (initial retreatment) and not with other factors.

Abstract
Antibiotics have played a crucial role in the reduction in the incidence of TB globally as evidenced by the fact that before the mid-20th century, the mortality rate within five years of the onset of the disease was 50%. The use of antibiotics has eliminated TB as a devastating disease, but the challenge of resistance to anti-TB drugs, which had already been described at the time of the introduction of streptomycin, has become a major global issue in disease management. Mismanagement of multidrug-resistant tuberculosis (MDR-TB) cases, resulting from intermittent drug use, prescription errors, and non-compliance of patients, has been identified as a critical risk factor for the development of extensively drug-resistant tuberculosis (XDR-TB). Antimicrobial resistance (AMR) in TB is a multi-factorial, complex problem of microbes evolving to escape antibiotics, the gradual decline in antibiotic development, and different economic and social conditions. In this review, we summarize recent advances in our understanding of how Mycobacterium tuberculosis evolves drug resistance. We also highlight the importance of developing shorter regimens that rapidly reach bacteria in diverse host environments, eradicating all mycobacterial populations and preventing the evolution of drug resistance. Lastly, we also emphasize that the current burden of this ancient disease is driven by a combination of complex interactions between mycobacterial and host factors, and that only a holistic approach that effectively addresses all the critical issues associated with drug resistance will limit the further spread of drug-resistant strains throughout the community.

Abstract
OBJECTIVE To estimate the prevalence and risk factors associated with tuberculosis (TB) among people living with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) in China. METHODS A systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. After the literature was screened based on the inclusion and exclusion criteria, STATA® version 17.0 software was used for the meta-analysis. The heterogeneity among study data was assessed using I2 statistics. Subgroup analysis and meta-regressions were performed to further explore the source of heterogeneity. RESULTS A total of 5241 studies were retrieved. Of these, 44 studies were found to be eligible. The pooled prevalence of HIV/TB co-infection was 6.0%. The risk factors for HIV/TB co-infection included a low CD4+ T cell count, smoking, intravenous drug use and several other sociodemographic and clinical factors. Bacillus Calmette-Guérin (BCG) vaccination history was a protective factor. CONCLUSION A high prevalence of TB was observed among people living with HIV/AIDS in China. Low CD4+ T cell count, smoking, and intravenous drug use were the primary risk factors for HIV/TB co-infection, whereas BCG vaccination history was a protective factor. Checking for TB should be prioritized in HIV screening and healthcare access. SYSTEMATIC REVIEW REGISTRATION Registered on PROSPERO, Identifier: CRD42022297754.
