[PMID: 38765044 PMCID: PMC11097054 DOI: 10.1016/j.heliyon.2024.e30939] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 05/08/2024] [Accepted: 05/08/2024] [Indexed: 05/21/2024] Open
Abstract
Background Co-infection of Mycobacterium tuberculosis (MTB) and the Human Immunodeficiency Virus (HIV) is a major global public health issue, particularly in border areas of resource-limited nations, including Ethiopia. Objective To explore the prevalence and associated variables of MTB/HIV co-infection among PTB presumptive patients in Northwest Ethiopia. Methods From February to August 2021, a cross-sectional institutional investigation was conducted at the Metema and Abrehajira hospitals. Semi-structured questionnaires were used to collect socio-demographic and clinical data. The MTB/RIF Xpert assay was used to process sputum, and 3 ml of veins blood was collected for HIV rapid test (STAT-PAK, ABON, and SD BIOLINE HIV test algorithm) following the Ethiopian National HIV test algorithm. The Gene Xpert assay's sample processing control was checked to ensure data quality. Data entered into Epi-Data were exported to SPSS version 20 for analysis. Statistically significant variables (p-value ≤0.2) from bivariable analysis were included in multivariable analysis. A p-value ≤ 0.05 was judged statistically significant. Results This study included 314 PTB presumptive patients with a median age of 35.0 years, of which 178 (56.69 %) were males. Among all patients, 40(12.7 %) and 51(16.2 %) were PTB, and HIV seropositivity, respectively. Of the PTB patients, 14/40 (35 %) (95 % CI: 24.4-45.6) were co-infected with HIV/AIDS. Married patients were 70 % less likely than unmarried individuals (AOR = 0.3 CI; 0.07-0.98) to have MTB/HIV co-infection. Patients who had contact history with MDR-TB patients (AOR = 5 CI; 1.37-18.00), and those who had a history of alcohol use (AOR = 12.2 CI; 2.56-57.8) were more likely to have MTB-HIV co-infection than their peers. Conclusion Our findings showed that MTB-HIV co-infection is one of the most important community health concerns in the study area. Therefore, MTB/HIV cooperation activities should be fully in place to prevent co-infection and its impact on the population.

Abstract
Tuberculosis (TB) is a disease caused by the bacillus Mycobacterium tuberculosis (MTB). Human immunodeficiency virus (HIV) infection and type 2 diabetes mellitus (T2DM) are among the main risk factors for the development of TB and increase the risk of drug-resistant TB developing (DR-TB). The aim of this study was to estimate the prevalence of DR-TB in patients with HIV or T2DM in Sinaloa, Mexico. This was an observational and cross-sectional study. The analysis was conducted using the clinical data of patients registered on the National Epidemiological Surveillance System for TB (SINAVE/PUI-TB) platform with a presumed diagnosis of TB during 2019 to 2021 in Sinaloa, Mexico. The prevalence of DR-TB was estimated in HIV and T2DM patients, as well as the odds ratios for their sociodemographic variables, using the Chi-square test. There were 2, 4, and 4 TB-HIV cases and 2, 6, and 9 TB-T2DM cases during 2019, 2020, and 2021, respectively, whereas there were 2 and 1 DRTB-HIV and DRTB-T2DM cases, respectively. The results indicated that the WHO guidelines for DR-TB were not properly applied to this high-risk population. Hence, the appropriate application of guidelines for TB and DR-TB detection in these patients needs to be immediately implemented by the State health system.

[PMID: 38152299 PMCID: PMC10751920 DOI: 10.3389/fmed.2023.1266780] [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: 07/25/2023] [Accepted: 11/21/2023] [Indexed: 12/29/2023] Open
Abstract
Introduction Border areas are important sites for disseminating Mycobacterium tuberculosis among individuals living in such areas. This study examined patients with suspected pulmonary tuberculosis (PTB) visiting the Abrihajira and Metema hospitals in northwest Ethiopia to investigate the prevalence of rifampicin-resistant Mycobacterium tuberculosis (RR-MTB), multidrug-resistant Mycobacterium tuberculosis (MDR-MTB), and risk factors related to Mycobacterium tuberculosis infection. Methods A hospital-based cross-sectional study was conducted from February to August 2021 among 314 PTB presumptive patients. Xpert MTB/RIF and line probe assays (LPA) were used to process sputum samples. Data were imported into the Epi-Data 3.1 program and exported to Statistical Package for the Social Sciences (SPSS) version 20.0 (SPSS, Chicago, IL, United States) to conduct the analysis. A logistic regression analysis was used to investigate the relationship between the dependent and independent variables. A value of p of <0.05 denoted statistical significance. Results Of the total (314) PTB presumptive patients who participated in this study, 178 (56.69%) were men, and 165 (52.5%) were from 25 to 50 years of age with a median age of 35.00 (inter-quartile: 25-45 years). Among all patients, 12.7% had PTB by Gene Xpert and 7/314 (2.23%) were resistant to rifampicin. Among patients enrolled, 4/314 (1.27%) had MDR-MTB (resistant to RIF and INH) by LPA. Regarding the risk factors assessed, primary level of education, sputum production, night sweating, respiratory disorder, contact history of TB, history of MDR-MTB infection, history of alcohol use, and cigarette smoking showed statistical significance with the prevalence of PTB (p ≤ 0.05). Discussion This study observed a high prevalence of PTB, RR-MTB, and MDR-MTB compared with many other previous studies conducted in Ethiopia. Among the assessed risk factors that could be associated with the prevalence of PTB, eight were statistically significant. This prevalence, resistance, and statistically significant variables are the evidence to which more emphasis should be given to the country's border areas.

Heliyon 2023; 9:e19554. [PMID: 37809604 PMCID: PMC10558782 DOI: 10.1016/j.heliyon.2023.e19554] [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: 11/23/2022] [Revised: 08/08/2023] [Accepted: 08/25/2023] [Indexed: 10/10/2023] Open
Abstract
Background Drug-resistant tuberculosis continues to be a global public health threat. Ethiopia is one of the high-burden countries for tuberculosis and multi-drug resistant tuberculosis. The estimated annual incidents of tuberculosis were 119 per 100,000 populations in 2021 and the prevalence of multi-drug resistance tuberculosis is about 0.7% among newly diagnosed cases in Ethiopia. On time detection of rifampicin resistance is essential for the management of the disease and earlier treatment initiation. Among the different diagnostic tests; Xpert is widely used for the rapid detection of Mycobacterium tuberculosis and rifampicin resistant in the country. The prevalence of rifampicin resistance-pulmonary tuberculosis varied from locality to locality and the estimated national prevalence of rifampicin resistance pulmonary tuberculosis is not available in the country. Therefore, the aim of this meta-analysis was to summarize the results of available studies and generate pooled prevalence estimate of rifampicin resistance pulmonary tuberculosis in Ethiopia. Methods Literature search was carried out using PubMed and Scopus public databases. Original articles conducted in Ethiopia and those containing a prevalence report of rifampicin resistance pulmonary tuberculosis diagnosed by Xpert Mycobacterium tuberculosis/rifampicin resistance assay were included in the meta-analysis. All retrospective and prospective studies published until May 2022 were screened in the study. The methodological qualities of included article were assessed using Joanna Briggs Institute quality assessment tool for cross-sectional studies. Random effect model was used to determine the pooled prevalence of rifampicin resistance pulmonary tuberculosis. Subgroup analysis and regression were carried out across regional states and study designs. Heterogeneity across studies was assessed using I2 test. The data were analyzed using STATA version 14. Result A total of 1570 titles were identified and 34 studies met the inclusion criteria. Of the total 17,292 pulmonary tuberculosis patients who were identified from the included articles, 1669 were rifampicin resistance pulmonary tuberculosis. The pooled prevalence of rifampicin resistant among pulmonary tuberculosis patients diagnosed with Xpert Mycobacterium tuberculosis/rifampicin resistance assay was 9.67% (95% CI: 8.11-11.24). The highest pooled prevalence was from Oromia11.84% (95% CI: 4.49-19.2%) and the lowest rifampicin resistance was identified in Amhara Regional State, 8.51% (95% CI: 5.96-11.06%). The pooled prevalence rates of rifampicin resistant among pulmonary tuberculosis patients were 10.18% (95% CI: 6.85-13.51) and 9.57% (95% CI: 7.68-11.47) in prospective and retrospective types of cross-sectional studies. Conclusion Our study showed that the pooled prevalence of rifampicin resistance among pulmonary tuberculosis patients was 9.67%. This showed that the occurrence of rifampicin resistance pulmonary tuberculosis among Mycobacterium tuberculosis patients remains high in Ethiopia. Regional state wise, rifampicin resistance variation was small. Further meta-analysis of factors associated with rifampicin resistance among pulmonary tuberculosis patients as well as among extrapulmonary Mycobacterium tuberculosis cases should be carried out.

Abstract
Objective This study aimed to determine the frequencies and trends of Mycobacterium tuberculosis and rifampicin resistance among presumptive tuberculosis patients in Ethiopia, who were tested using the Xpert MTB/RIF assay between 2014 and 2021. Methods Data were collected retrospectively from patient registries. Laboratory-based data were extracted from the national tuberculosis (TB) referral laboratory database. All patients referred to the National Tuberculosis Reference Laboratory (NTRL) for TB diagnosis from all over the country between March 1, 2014 and September 30, 2021, and tested using the Xpert MTB/RIF assay, were included. The extracted data were entered into a Microsoft Excel sheet and analyzed by Statistical Package for Social Sciences (SPSS) version 23. Results Among a total of 13 772 individuals tested using the Xpert MTB/RIF assay, the majority (8223; 59.7%) were males, and 48.5% (6678) of the individuals were aged between 15 and 39 years. Mycobacterium tuberculosis (MTB) was detected in 17.0% (2347) of the examined individuals. Of the detected MTB cases, nearly 9.9% (233) were rifampicin resistant (RR-TB), while 24 (1.0%) were RR-intermediate. Among all RR-TB cases, more than half (125; 53.6%) were detected in males, and 105 were new TB cases. Extrapulmonary (EPTB) patients had a greater rate of rifampicin resistance (11.0%) than pulmonary (PTB) patients (9.6%). Conclusion The frequency of TB and RR-TB remains high in the study setting. RR-TB was found to have a statistically significant association with previous anti-TB medication treatment. As a result, improving treatment adherence in recognized instances could assist in preventing MTB and RR-TB cases.

Detection of Mycobacterium tuberculosis using Gene Xpert-MTB/RIF assay among tuberculosis suspected patients at Mizan-Tepi university teaching hospital, southwest Ethiopia: An institution based cross-sectional study. PLoS One 2022; 17:e0277536. [PMID: 36417400 PMCID: PMC9683564 DOI: 10.1371/journal.pone.0277536] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Accepted: 10/31/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Consistently deciding its current extent and chance elements of tuberculosis (TB) in all levels of clinical settings contributes to the anticipation and control exertion of the disease. In Ethiopia, updated information is still needed at every healthcare level and in different risk groups to monitor the national program's performance, which aims to attain the 2035 goal. Hence, this study aimed to generate additional evidence data on the magnitude of Mycobacterium tuberculosis using the Gene Xpert assay among TB-suspected patients at Mizan-Tepi university teaching hospital, southwest Ethiopia. METHODS A cross-sectional descriptive study was conducted from June to September 30, 2021. The required socio-demographic and other risk factor data were collected from a total of 422 suspected TB patients using a structured questionnaire. Approximately 392 pulmonary and 30 extra-pulmonary samples were collected and examined using the Gene Xpert-MTB/RIF assay. The statistical package for social sciences (SPSS) version 25 software was used to analyze the data. RESULTS In this study, Mycobacterium tuberculosis was detected in 12.5% (49/392) of pulmonary samples and 13.3% (4/30) of extra-pulmonary samples, giving an overall TB positivity of 12.6% (53/422). Rifampicin-resistant M. tuberculosis was detected in 3/53 (5.7%). Male sex (AOR: 2.54; 95% CI: 1.210, 5.354), previous contact (AOR: 4.25; 95% CI: 1.790, 10.092), smoking cigarette (AOR: 4.708; 95% CI: 1.004, 22.081), being HIV-positive (AOR: 4.27; 95% CI: 1.606, 11.344), and malnutrition (AOR: 3.55; 95% CI: 1.175, 10.747) were all significantly associated with M. tuberculosis detection using the GeneXpert MTB/RIF assay. CONCLUSION The overall frequency of M. tuberculosis in this study was still significant in different risk groups, despite the proposed strategies, which aimed to reduce TB prevalence to as low as 10 per 100,000 populations by 2035. Early case detection with better diagnostic tools and public health measures are important prevention and control strategies to meet the proposed target and reduce the burden of TB in the country.

Abstract
With the continuous development of medical science and technology, especially with the advent of the era of precision diagnosis and treatment, molecular biology detection technology is widely valued and applied as an aid to early diagnosis of tuberculosis. The GeneXpert Mycobacterium tuberculosis Branching (MTB) technology is a suite of semi-nested real-time fluorescent quantitative PCR in vitro diagnostic technologies developed by Cepheid Inc. It targets the rifampicin resistance gene, rpoB, and can detect both MTB and resistance to rifampicin within 2 h. This review analyzed the papers related to GeneXpert using bibliometric software CiteSpace and Bibliometrix. A total of 151 articles were analyzed, spanning from 2011 to 2021. This bibliometrics-based review summarizes the history of the development of GeneXpert in tuberculosis diagnosis and its current status. Contributions of different countries to the topic, journal analysis, key paper analysis, and clustering of keywords were used to analyze this topic.

Abstract
BACKGROUND With a progressive increase in the aging process, the challenges posed by pulmonary tuberculosis (PTB) are also increasing for the elderly population. OBJECTIVE This study aimed to identify the epidemiological distribution of PTB among the elderly, forecast the achievement of the World Health Organization's 2025 goal in this specific group, and predict further advancement of PTB in the eastern area of China. METHODS All notified active PTB cases aged ≥65 years from Zhejiang Province were screened and analyzed. The general epidemiological characteristics were depicted and presented using the ArcGIS software. Further prediction of PTB was performed using R and SPSS software programs. RESULTS Altogether 41,431 cases aged ≥65 years were identified by the surveillance system from 2015 to 2020. After excluding extrapulmonary TB cases, we identified 39,832 PTB cases, including laboratory-confirmed (23,664, 59.41%) and clinically diagnosed (16,168, 40.59%) PTB. The notified PTB incidence indicated an evident downward trend with a reduction of 30%; however, the incidence of bacteriologically positive cases was steady at approximately 60/100,000. Based on the geographical distribution, Quzhou and Jinhua Cities had a higher PTB incidence among the elderly. The delay in PTB diagnosis was identified, and a significantly prolonged treatment course was observed in the elderly. Moreover, a 50% reduction of PTB incidence by the middle of 2024 was predicted using a linear regression model. It was found that using the exponential smoothing model would be better to predict the PTB trend in the elderly than a seasonal autoregressive integrated moving average model. CONCLUSIONS More comprehensive and effective interventions such as active PTB screening combined with physical checkup and succinct health education should be implemented and strengthened in the elderly. A more systematic assessment of the PTB epidemic trend in the elderly population should be considered to incorporate more predictive factors.

Abstract
Background Mycobacterium Tuberculosis (MTB) and its drug resistance form are the devastating infectious diseases in the world. It is the major cause of morbidity and mortality in low-income countries with Ethiopia carrying a heavy burden. Data on the magnitude of MTB and rifampicin resistance using Xpert- MTB/RIF assay is limited in the study area. Therefore, this study aimed to assess the prevalence of Mycobacterium tuberculosis and rifampicin resistance among presumptive TB patients using GeneXpert at Motta General Hospital, North West Ethiopia. Methods A retrospective cross-sectional study was conducted from 1st October to 30 November 2020 among patients tested for GeneXpert at Motta General Hospital, Northwest Ethiopia. Data recorded on GeneXpert test results were collected on laboratory registration book in Microbiology laboratory. Data were analyzed by using the Statistical Package for Social Sciences (SPSS) version 20. Results A total of 4109 specimens were tested using the GeneXpert automated system. Of these, the majority 2148 (52.3%) of participants were males and 1961 (47.7%) were females. Similarly, about 1553 (37.8%) were in the age range of 25-44 years followed by 1347 (32.8%) in 45-64 years. Moreover, about 2486 (60.5%) participants were from rural. The overall prevalence of M. tuberculosis was 346 (8.4%) among these, the majority 222 (5.4%) had unknown HIV status, 48 (1.2%) were HIV positive, and 314 (7.6%) was new MTB cases. The overall prevalence of rifampicin resistance was 15 (4.3%) and 8(1.7%) were intermediate. Among rifampicin resistance, 10 (2.9%) were males, 8(2.3%) lived in rural, 9 (2.6%) had unknown HIV status, 13 (3.8%) were new TB patients, and 13 (3.8%) had pulmonary tuberculosis. Conclusion The prevalence of M. tuberculosis was 8.4% and relatively higher rate of rifampicin-resistant M. tuberculosis was found.

Abstract
Background Tuberculosis (TB) has remained as a top global public health concern of the 21st century. It is the leading cause of morbidity and mortality among people living with human immunodeficiency virus (HIV) worldwide. Objective The study aimed to investigate the magnitude of pulmonary tuberculosis and its associated factors among HIV-positive patients attending antiretroviral treatment (ART) clinic in Debre Tabor specialized hospital, Northwest, Ethiopia. Methods A hospital-based cross-sectional study was conducted among 362 HIV-positive adult participants attending the ART clinic from October 1st to December 30th 2019. Socio-demographic data were collected using a pre-tested questionnaire. Sputum was collected aseptically into a sterile and leak-proof container. Following aseptic techniques, each sample was processed using the GeneXpert assay based on the manufacturer’s instructions. Similarly, about 3–5 mL of whole blood was drawn for CD4+ T-cell count and plasma viral load tests following standard blood collection procedures. CD4+ T-cell count was performed using the BD FACS caliber flow cytometry while the plasma viral load was performed by using a quantitative real-time polymerase chain reaction. Then, collected data were double-checked, cleaned and entered into Epi-Info version 7.2.0.1 and exported to SPSS version 20.0 for further statistical analysis. The bivariate and multivariate logistic regression were conducted to address risk factor analysis. The 95%confidence interval with its corresponding cure and adjusted odds ratio was computed. Finally, p-value ≤0.05 was considered as a statistically significant association. Results In this study, the overall prevalence of tuberculosis among HIV-positive patients was 18 [(5%), 95% CI: 2.8–7.5]. A high viral load (≥1000 copies/mL) was positively associated [AOR (95% CI: 6.4 (1.6–25.7)), p < 0.001] with developing tuberculosis among HIV-positive patients. Conclusion The prevalence of TB is low among ART-receiving patients in our study site.

[PMID: 33116664 PMCID: PMC7547769 DOI: 10.2147/idr.s263023] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Accepted: 08/25/2020] [Indexed: 01/16/2023] Open
Abstract
Background Drug-resistant tuberculosis remains a major public health threat complicating tuberculosis control programs globally. Data on rifampicin resistance (RR), which is a surrogate marker for multidrug resistance, are limited among Ethiopian tuberculosis patients. This study aimed to determine the magnitude of rifampicin-resistant Mycobacterium tuberculosis (RR-MTB) among presumptive tuberculosis patients attending St. Peter Tuberculosis Specialized Hospital, Addis Ababa, Ethiopia. Patients and Methods A retrospective cross-sectional study was conducted at St. Peter Tuberculosis Specialized Hospital from January 2016 to December 2018. After checking completeness of the necessary information, data of tuberculosis-presumptive cases who underwent Gene Xpert® testing were collected from medical records using a data-extraction format prepared for this study purpose. Data were double entered and analyzed using SPSS version 20 statistical software. Results A total of 12,685 presumptive tuberculosis patients were included; of whom 54.5% were males and the mean age of the study participants was 40.3±18.7 years. Mycobacterium tuberculosis (MTB) was detected in 1714 participants (13.5%). Of these MTB cases, 169 cases (9.8%) were confirmed to have RR-MTB. Prevalence of MTB was relatively higher among males (15.1%, P=0.78); whereas RR-MTB was higher among females (10.3%, P=0.81). The incidence of MTB and RR-MTB was significantly associated with treatment history (P=0.042 and P=0.025), respectively. HIV infection has significantly associated with incidence of RR-MTB (P=0.032), but not with MTB (P˃0.05). Prevalence of MTB and RR-MTB had a declining trend through time, being 16.7% and 12.9%, 12.8% and 9.1%, and 12.2% and 7.9% in 2016, 2017 and 2018, respectively. Conclusion This study showed a decreasing trend of both MTB and RR-MTB from 2016 to 2018 in an MTB, MDR-MTB, and TB/HIV co-infection high-burden setting, Addis Ababa, Ethiopia. Occurrence of MTB and RR-MTB was associated with treatment history. Therefore, improvement in treatment adherence of identified cases would be helpful to prevent emergence or re-emergence of MTB and RR-MTB cases.
