Abstract
Background The current six months regimen for drug-susceptible tuberculosis (TB) is long, complex, and requires adherence monitoring. TB hair drug level assay is one innovative approach to monitor TB treatment adherence however, its acceptability in the context of African multi-cultural settings is not known. Objective To determine the acceptability of hair harvest and testing as a TB therapeutic drug monitoring method. Methods The study explored perceptions, and lived experiences among TB patients with regard to using hair harvest and testing as a method of tuberculosis therapeutic drug monitoring in the context of their cultural beliefs, and faith. We used a descriptive phenomenological approach. Results Four main themes emerged namely: participants' perceptions about the cultural meaning of their body parts; perceptions about hair having any medical value or meaning; perceptions about hospitals starting to use hair harvest and testing for routine hospital TB treatment adherence monitoring; and perceived advantages and disadvantages of using hair for treatment adherence monitoring. Overall, we found that using hair to monitor adherence was acceptable to TB patients provided the hair was harvested and tested by a medical worker. Conclusion Hair harvest for medical testing is acceptable to TB patients on the condition that it is conducted by a medical worker.

Li Q, Zhang J, Ma L, Wu C, Zhao J, Guan W, Li X, Yang X, Wen F. ILC2s induce adaptive Th2-type immunity in different stages of tuberculosis through the Notch-GATA3 pathway. Int Immunopharmacol 2021; 101:108330. [PMID: 34862127 DOI: 10.1016/j.intimp.2021.108330] [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: 04/22/2021] [Revised: 10/26/2021] [Accepted: 10/28/2021] [Indexed: 02/05/2023]
Abstract
The study is to investigate the roles of group 2 innate lymphoid cells (ILC2s) in different courses of tuberculosis (TB). Serum and PBMCs were respectively isolated from the TST negative, LTBI (latent TB infection), ATB (active TB) and RTB (recurrent TB) patients. Flow cytometry was used to detect Th1, Th2 and ILC2s in the peripheral blood. The mRNA and protein levels of GATA3, RORα, CRTH2, Hes1, Notch1, NF-κB, and ID2 were detected by qRT-PCR and Western blotting. ILC2 cells from ATB and RTB patients were stimulated with rJagged2 or DAPT in vitro, and co-cultured with CD4+ T cells from TST negative group. ELISA was used to detect cytokine levels. The results showed that compared with the TST negative or LTBI group, Th2 cells and serum IL-4 in ATB group increased dramatically, accompanied by an increase of Th2/Th1 ratio in ATB patients, especially in RTB group. However, ILC2s in the ATB and RTB group increased significantly, along with increased GATA3, RORα, and CRTH2 levels. After rJagged2 stimulation in vitro, the levels of Hes1, Notch1, NF-κB, RORα, GATA3 and ID2 and those of IL-4, IL-5 and IL-13 were significantly increased. These effects were abrogated by DAPT treatment. Then, ILC2s, especially those from RTB patients, induced Th2-type immune response after co-culturing with CD4+ T cells. In conclusion, our results suggest that ILC2s may promote Th2-type immune response in different stages of TB via the Notch-GATA3 pathway.

Abstract
Objective This study aims to evaluate plasma S100A9 levels in tuberculosis (TB) patients with admission to the ICU as a marker to predict the risk of death for pulmonary severe TB. Methods This study enrolled 256 severe TB patients admitted to Beijing Chest Hospital from Jan to Dec 2019. The S100A9 levels were measured by ELISA. Standard clinical parameters were collected. The non-parametric Mann-Whitney test, t-test, and chi-square test were applied to statistical comparison. A multivariable analysis was performed to identify risk factors for death. Results The plasma S100A9 levels were higher in non-survivors (25.88, 16.77-44.64) compared to survivors (15.51, 13.67-19.94). S100A9 performed better than Acute Physiology and Chronic Health Evaluation (APACHE II) score in predicting death, with AUC of 0.725, sensitivity of 65.5%, and specificity of 80.3%. By combining APACHE II score together with the S100A9 levels we got an AUC of 0.754 (95% CI 0.68 to 0.82) in predicting death. Lastly, S100A9 levels were significantly higher in patients with APACHE II score >17.5, sputum smear-positive, early death, and high cavitary lesions numbers, all of which were related to TB progression. Conclusion Measurement and monitoring levels of plasma S100A9 in severe TB patients could facilitate the evaluation of patients with high risk at the early stage, which may help to improve the treatment outcome for TB patients.
