A 32-year global analyses on dynamic trends and geospatial visualization of genital tuberculosis and female infertility: A scientometric study. Heliyon 2024; 10:e31396. [PMID: 38818201 PMCID: PMC11137401 DOI: 10.1016/j.heliyon.2024.e31396] [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: 11/16/2023] [Revised: 05/14/2024] [Accepted: 05/15/2024] [Indexed: 06/01/2024] Open
Abstract
Introduction Genital tuberculosis (GT) is an infection that can affect the female reproductive system, including the uterus, cervix, and ovaries. Objective To perform a scientometric exploration to analyze the spatiotemporal trend, evolution, and emerging patterns of scholarly output on GT and female infertility. Methods An observational, descriptive, retrospective study employing a scientometric methodology was carried out. Metadata from scholarly articles spanning the years 1990-2022 were extracted from the Web of Science. The metadata from the chosen articles, totaling 172 manuscripts, were exported on May 17, 2023, in plain text format, which will allow the analysis and integration of the data in the software used. Results We found at 111 sources and found 172 documents on tuberculosis and female infertility. We observed an average annual growth rate of 7.46 %, and the average age of the documents was 10.4 years. The dual overlay map showed the distribution of scientific publications on tuberculosis and female infertility. Journals on the left side of the map are cited mainly in the journals on the right. We found that Clinical Infectious Diseases and Lancet journals condensed patterns and trends in 1995, while the Indian Journal of Tuberculosis did so in 1996. Dheda K., Joubert JJ., and Wang Y. were the authors who had India, Iran, and China as their main affiliation, respectively, and they mainly published their studies in the "American Journal of Respiratory and Critical Care Medicine" and "Tropical Doctor," among others. Conclusions This bibliometric study examined different sources and found an average annual growth rate of 7.46 %. Each article received an average of 16.48 citations. Different collaborative networks between countries were observed. In addition, there was a steady growth in published research in the field of tuberculosis and female infertility.

Wang Z, Zhang X, Dai B, Li D, Chen X. Analysis of the potential regulatory mechanisms of female and latent genital tuberculosis affecting ovarian reserve function using untargeted metabolomics. Sci Rep 2024; 14:9519. [PMID: 38664479 PMCID: PMC11045857 DOI: 10.1038/s41598-024-60167-7] [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: 02/22/2024] [Accepted: 04/19/2024] [Indexed: 04/28/2024] Open
Abstract
Female and latent genital tuberculosis (FGTB and LGTB) in young women may lead to infertility by damaging ovarian reserve function, but the regulatory mechanisms remain unclear. In this study, we investigated the effects of FGTB and LGTB on ovarian reserve function and potential regulatory mechanisms by untargeted metabolomics of follicular fluid, aiming to provide insights for the clinical management and treatment approaches for afflicted women. We recruited 19 patients with FGTB, 16 patients with LGTB, and 16 healthy women as a control group. Clinical data analysis revealed that both the FGTB and LGTB groups had significantly lower ovarian reserve marker levels compared to the control group, including lower anti-Müllerian hormone levels (FGTB: 0.82 [0.6, 1.1] μg/L; LGTB: 1.57 [1.3, 1.8] μg/L vs. control: 3.29 [2.9, 3.5] μg/L), reduced antral follicular counts (FGTB: 6 [5.5, 9.5]; LGTB: 10.5 [7, 12.3] vs. control: 17 [14.5, 18]), and fewer retrieved oocytes (FGTB: 3 [2, 5]; LGTB: 8 [4, 8.3] vs. control: 14.5 [11.5, 15.3]). Conversely, these groups exhibited higher ovarian response marker levels, such as longer gonadotropin treatment days (FGTB: 12 [10.5, 12.5]; LGTB: 11 [10.8, 11.3] vs. control: 10 [8.8, 10]) and increased gonadotropin dosage requirements (FGTB: 3300 [3075, 3637.5] U; LGTB: 3037.5 [2700, 3225] U vs. control: 2531.25 [2337.5, 2943.8] U). All comparisons were statistically significant at P < 0.05. The results suggested that FGTB and LGTB have adverse effects on ovarian reserve and response. Untargeted metabolomic analysis identified 92 and 80 differential metabolites in the control vs. FGTB and control vs. LGTB groups, respectively. Pathway enrichment analysis revealed significant alterations in metabolic pathways in the FGTB and LGTB groups compared to the control group (P < 0.05), with specific changes noted in galactose metabolism, biotin metabolism, steroid hormone biosynthesis, and nicotinate and nicotinamide metabolism in the FGTB group, and caffeine metabolism, primary bile acid biosynthesis, steroid hormone biosynthesis, and glycerophospholipid metabolism in the LGTB group. The analysis of metabolic levels has revealed the potential mechanisms by which FGTB and LGTB affect ovarian reserve function, namely through alterations in metabolic pathways. The study emphasizes the importance of comprehending the metabolic alterations associated with FGTB and LGTB, which is of considerable relevance for the clinical management and therapeutic approaches in afflicted women.

Abstract
INTRODUCTION Diagnosis of extrapulmonary tuberculosis (EPTB) is an arduous task owing to different anatomical locations, unusual clinical presentations, and sparse bacillary load in clinical specimens. Although GeneXpert® MTB/RIF is a windfall in TB diagnostics including EPTB, it yields low sensitivities but high specificities in many EPTB specimens. To further improve the sensitivity of GeneXpert®, GeneXpert® Ultra, a fully nested real-time PCR targeting IS6110, IS1081 and rpoB (Rv0664) has been endorsed by the WHO (2017), wherein melt curve analysis is utilized to detect rifampicin-resistance (RIF-R). AREA COVERED We described the assay chemistry/work design of Xpert Ultra and evaluated its performance in several EPTB types, that is, TB lymphadenitis, TB pleuritis, TB meningitis, and so on, against the microbiological reference standard or composite reference standard. Notably, Xpert Ultra exhibited better sensitivities than Xpert, but mostly at the compensation of specificity values. Moreover, Xpert Ultra exhibited low false-negative and false-positive RIF-R results, compared with Xpert. We also detailed other molecular tests, that is, Truenat MTBTM/TruPlus, commercial real-time PCR, line probe assay, and so on, for EPTB diagnosis. EXPERT OPINION A combination of clinical features, imaging, histopathological findings, and Xpert Ultra are adequate for definite EPTB diagnosis so as to initiate an early anti-tubercular therapy.

Abstract
A multitargeted loop-mediated isothermal amplification (MT-LAMP) assay targeting mpt64 (Rv1980c) and IS6110 was designed to diagnose genitourinary tuberculosis (GUTB) cases. While assessing gel-based, hydroxynaphthol blue (HNB) and SYBR Green I MT-LAMP assays on GUTB specimens (n = 28) in a pilot study, both gel-based/SYBR Green I assays exhibited better sensitivity than HNB LAMP. Since SYBR Green MT-LAMP is easier to perform compared with a gel-based assay, a higher number of GUTB specimens (n = 55) were evaluated by SYBR Green MT-LAMP, wherein 85.5% sensitivity and 94.4% specificity (n = 36) were obtained. Moreover, the sensitivity attained by MT-LAMP was significantly higher (p < 0.05) than with multiplex-PCR (mpt64 + IS6110). After further validating these MT-LAMP data in different epidemiological settings, this assay may be developed as a diagnostic kit.

Abstract
INTRODUCTION Pleural tuberculosis (TB) is the archetype of extrapulmonary TB (EPTB), which mainly affects the pleural space and leads to exudative pleural effusion. Diagnosis of pleural TB is a difficult task predominantly due to atypical clinical presentations and sparse bacillary load in clinical specimens. AREA COVERED We reviewed the current literature on the globally existing conventional/latest modalities for diagnosing pleural TB. Bacteriological examination (smear/culture), tuberculin skin testing/interferon-γ release assays, biochemical testing, imaging and histopathological/cytological examination are the main modalities. Moreover, nucleic acid amplification tests (NAATs), i.e. loop-mediated isothermal amplification, PCR/multiplex-PCR, nested-PCR, real-time PCR and GeneXpert® MTB/RIF are being utilized. Currently, GeneXpert Ultra, Truenat MTBTM, detection of circulating Mycobacterium tuberculosis (Mtb) cell-free DNA by NAATs, aptamer-linked immobilized sorbent assay and immuno-PCR (I-PCR) have also been exploited. EXPERT OPINION Routine tests are not adequate for effective pleural TB diagnosis. The latest molecular/immunological tests as discussed above, and the other tools, i.e. real-time I-PCR/nanoparticle-based I-PCR and identification of Mtb biomarkers within urinary/serum extracellular vesicles being utilized for pulmonary TB and other EPTB types may also be exploited to diagnose pleural TB. Reliable diagnosis and early therapy would reduce the serious complications associated with pleural TB, i.e. TB empyema, pleural fibrosis, etc.

Abstract
Aim: Diagnosis of urogenital tuberculosis (UGTB) is difficult and there is an immediate need to develop a reliable diagnostic test. Methods: A real-time immuno-PCR (RT-I-PCR) was developed to identify a cocktail of MPT-64 + ESAT-6 in both male/female UGTB patients comprising five confirmed cases, 40 clinically suspected cases and 37 non-TB controls, from whom mid-stream urine specimens were collected, while endometrial biopsies of female patients were obtained on day 1 of their menstrual cycle. Results obtained by RT-I-PCR were compared with I-PCR/ELISA and GeneXpert. Results: A wide range (500 fg/ml-10 ng/ml) of MPT-64 + ESAT-6 was detected in UGTB specimens by RT-I-PCR, although ELISA showed a narrow range (2.5-11 ng/ml). Sensitivities of 80% and 82.2% were obtained by RT-I-PCR in clinically suspected and total UGTB cases, respectively, whereas 94.6% specificity was obtained. Concurrently, RT-I-PCR revealed significantly higher (p < 0.05-0.001) sensitivity than I-PCR/ELISA and GeneXpert. Conclusion: After improving the specificity, the authors may develop RT-I-PCR into a diagnostic kit.

Abstract
A multiplex-nested PCR (M-nested PCR) targeting mpt64 (Rv1980c) + IS6110 was designed to detect Mycobacterium tuberculosis (Mtb) DNA within urine (n = 35), endometrial biopsies (n = 22) and menstrual blood (n = 3) of male/female UGTB patients, and results were compared with M-PCR using the same targets. Detection limit of the purified Mtb DNA was found to be 1 fg by M-nested PCR, which was 106 -fold lower than M-PCR. Moreover, sensitivities of 100% and 81·8% were obtained in confirmed (n = 5) and clinically suspected UGTB (n = 55) cases, respectively, by M-nested PCR, with a specificity of 97·1% (n = 70). Sensitivities attained by M-nested PCR were significantly higher (p < 0·05) than M-PCR in both clinically suspected and total UGTB (n = 60) cases. To confirm the true PCR-negative results, an internal amplification control, that is, human β-globin gene (hbb) was incorporated in the M-nested PCR/M-PCR assays, wherein all the clinical specimens (positive/negative for mpt64/IS6110) were found to be positive for hbb. Some UGTB specimens (n = 35) were also subjected to GeneXpert® MTB/RIF assay that revealed a significantly lower (p < 0·001) sensitivity (17·1 vs 88·6%) than M-nested PCR, although high specificity (100%) was attained with GeneXpert. After validating the results in a higher number of UGTB specimens, our M-nested PCR may be translated into an attractive diagnostic kit.
