Background Mycobacterium kansasii as a nontuberculosis mycobacteria, naturally release extracellular vesicles (EVs) with widespread utilities. The aim of the present study was the extraction and biological evaluation of M. kansasii EV and its role in BALB/c mice immune modulatory by considering EVs medical usage specificities. Method Density gradient ultracentrifugation method was used to EVs extraction from standard species of M. kansasii. Biologic validation of EVs has been performed by physicochemical experiments. Immunization has been done by subcutaneous injection to BALB/c mice, then spleen cell isolation and lymphocyte transformation test and eventually ELISA cytokine assays were made for interleukin-10 (IL-10) and interferon-gamma (IFN-γ). IBM SPSS version 22 software (SPSS. Inc., Chicago, IL, USA) was used for the data calculation. The evaluation of variables was conducted using one sample t-test. Results Physicochemical experiment results contribute that extracted EVs have intransitive capability to use in immunization schedule. Finally, ELISA test results showed that EVs induced IL-10 production, but have no effect on IFN-γ. Conclusions In this current study, EVs were prepared in high-quality composition. The results of cytokine assay revealed that the extracted EVs have anti-inflammatory property. Accordingly, this macromolecule can be used as immune modulatory agents to prevent severe immune reactions, especially in lungs disorders.Background The aim of this study is to analyze interferon-gamma release assay (IGRA) data of foreign-born individuals in Japan derived from tuberculosis (TB) contact investigations. Methods A contact with a TB patient was considered to have occurred when an individual had contact with a TB patient for more than 8 h indoors. Z-VAD-FMK This is a retrospective cohort study, and all the TB contacts tested with IGRA during the contact investigations conducted by the Shinjuku city Health Office from 2015 through 2017 were enrolled. Results A total of 880 foreign-born contacts were investigated. The IGRA positivity of the contacts from China and Viet Nam were both 5.1% (95% confidence intervals [CIs] 3.2%-7.8% and 2.4%-9.5%, respectively), whereas that from Nepal and Myanmar were 24.4% (95% CI 16.0%-34.6%) and 23.3% (95% CI 9.9%-42.3%), respectively. Multiple logistic regression analysis showed that the risk factors were smear status of the index patient (1+ adjusted odds ratio [aOR] 6.2, 95% CI 1.2-30.5, smear status 3+ aOR 14.3, 95% CI 1.7-118.2), age of the contact (aOR 1.1, 95% CI 1.0-1.1 for 1 year increment), and being born in Nepal (aOR 5.6, 95% CI 2.8-11.2) and Myanmar (aOR 4.3, 95% CI 1.4-13.0), compared with China as reference. Conclusions In contact investigations involving foreign-born individuals, local health offices should carefully consider the composition of the TB contacts and expand the focus of the investigation, if deemed necessary.Background Treatment of Mycobacterium abscessus pulmonary disease (PD) is challenging with frequent side effects and uncertain rates of success. Methods We performed a retrospective review of all patients at our center with at least one respiratory sample positive for M. abscessus between 2014 and 2019. Electronic health records were reviewed to determine factors associated with M. abscessus infection and clinical outcomes. Results Thirty-seven patients were identified including 24 with cystic fibrosis (CF), 10 with bronchiectasis, two with chronic obstructive PD (COPD), and one with asthma. American Thoracic Society/Infectious Diseases Society of America criteria for nontuberculous mycobacteria PD were met in 21/37 (56.8%) of cases. Evidence of Aspergillus lung disease was noted in 18 (75.0%) CF patients compared with 3 (23.1%) non-CF patients (P = 0.005). Induction therapy for M. abscessus was given to 22/37 (59.5%) patients (18/24 [75%] with CF and 4/13 [30.8%] without CF). Median duration of induction therapy was 6 weeks (range 3-12). Maintenance antibiotic therapy was prescribed to 17/22 (77.3%) of treated patients. Culture conversion was seen in 15/24 (62.5%) of CF patients compared with 3/13 (23.1%) in the non-CF group (P = 0.034). Culture conversion occurred in 10/22 (45.5%) of treated patients compared with 8/15 (53.3%) untreated patients. Three patients (8.1%) died during follow-up one with CF and two with COPD. Conclusions Culture conversion following isolation of M. abscessus from respiratory samples not only is more common in CF than in patients without CF but also frequently occurs spontaneously in both groups. Targeted treatment for M. abscessus did not clearly impact rates of culture conversion.Background Understanding the current surveillance activity and the challenges is important to ensure a continuous success toward the elimination goal for tuberculosis (TB). South Batinah Governorate (SBG) ranked the fourth on the top reporting governorates in the period 2010-2016 in Oman. The objective of this study is to describe the epidemiological profile and activities of the surveillance program of TB in the SBG in the years 2017 and 2018. Methods A retrospective quantitative analysis and a qualitative review were performed to the surveillance data present in the department of disease surveillance and control in the SBG in the years 2017 and 2018. Results A total of 39 pulmonary TB (PTB) and 21 extrapulmonary TB (EPTB) cases were diagnosed in 2017 and 2018. More Omanis (22, 56.4%) were diagnosed with PTB compared to non-Omanis; however, the EPTB was solely diagnosed among Omanis (P less then 0.001). Majority of the TB patients (35%) were between 30 and 49 years. More than 50% of the TB cases of both the types were diagnosed in less then 3 months, and the median of diagnosis delay was 33.5 (standard deviation = 95.5). Bacillus Calmette-Guérin vaccine scar was present in only 20.5% of the PTB patients, compared to 57.1% of EPTB (P = 0.004). Patients with PTB presented mainly with cough (31, 79.5%), loss of weight and appetite (25, 64.1%), and fever (22, 56.4%). Enlarged lymph nodes and loss of weight and appetite were the common symptoms among EPTB patients, 38.1 for each (P less then 0.001). Staffing, incomplete notifications, difficulty in tracing the results, and absence of regular feedbacks are the major existing challenges. Conclusion SBG continues to sustain low incidence rate of tuberculosis; however, additional strategies are urgently required for further reduction. Hence, the priority is to enhance all essential components of the surveillance system at this stage.
