Identification of mycobacterial MPT-64 and ESAT-6 proteins in urogenital tuberculosis patients by real-time immuno-PCR

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.

Current updates in diagnosis of male urogenital tuberculosis

Introduction: Urogenital tuberculosis (UGTB) is a common manifestation of extrapulmonary TB (EPTB), which affects both men and women in a ratio of 2:1. Similar to other EPTB types, diagnosis of UGTB is quite challenging owing to atypical clinical presentation and paucibacillary nature of specimens. This review is primarily focused on the current updates developed in the diagnosis of male UGTB.Area covered: Smear/culture, imaging, histopathology, and interferon-γ release assays are the main modalities employed for detecting male UGTB cases. Moreover, we described the utility of nucleic acid amplification tests (NAATs), including loop-mediated isothermal amplification, PCR, nested-PCR, and GeneXpert (MTB/RIF) assays. The possibility of using other novel modalities, such as immuno-PCR (I-PCR), aptamer-linked immobilized sorbent assay (ALISA), and identification of circulating cell-free DNA (cfDNA) by NAATs were also discussed.Expert opinion: The current methods used for the diagnosis of male UGTB are not adequate. Therefore, the latest molecular/immunological tools, i.e. Xpert Ultra, Truenat MTB^TM, I-PCR, ALISA, and cfDNA detection employed for the diagnosis of other EPTB forms and pulmonary TB may also be exploited for UGTB diagnosis. Reliable and timely diagnosis of male UGTB may initiate an early start of anti-tubercular therapy that would reduce infertility and other complications associated with disease.

Testicular Cancer Incidence and Mortality Within Rural and Urban Regions

Purpose: Testicular cancer (TCa) is among the most common cancers within adolescent and young adult (AYA) male populations. However, information is limited to variations in incidence and mortality outside of racial/ethnic subgroups. Rural regions historically have a greater overall cancer incidence than urban regions, although some key differences exist regarding site. TCa-specific incidence and mortality disparities are not commonly reported in this context. This study aims to help fill that gap by providing discovery evidence if there is an association between US rural/urban regions and TCa incidence and mortality. Methods: Secondary analysis of Surveillance, Epidemiology, and End Results incidence and mortality data were employed to determine if rural/urban TCa incidence and mortality disparities exist among U.S. males. Results: There was a 2.6% increased rate of TCa in U.S. urban as compared with rural geographic regions from 2011 to 2015. When geographic region is disaggregated, rural regions see higher rates than urban. When factoring in race/ethnicity, White/Caucasians and Hispanics had statistically higher urban rates whereas American Indian/Alaskan Natives and Asian/Pacific Islander groups had statistically higher rural rates. Conclusion: Geographic regional TCa variation research is virtually nonexistent for U.S. males, specifically AYAs of color. Determining preliminary trends in rural and urban regions can assist in the creation of more targeted services, particularly among underserved and vulnerable populations that have tenuous access to health care, to reduce disparate health outcomes. Exploring geographic differences in TCa incidence and mortality can have implications within service industry, health care accessibility, and public health justice areas of research and outreach.
