Abstract
BACKGROUND In 2017, Korea implemented nationwide latent tuberculosis infection (LTBI) project targeting healthcare workers (HCWs). We aimed to assess its performance using the cascade of care model. METHODS We included 45,503 employees of medical institutions with positive interferon-gamma release assay result who participated between March 2017 and December 2018. We described percentages of LTBI participants completing each step in the cascade of care. Poisson regression model was conducted to assess individual characteristics and factors associated with not-visiting clinics for further care, not-initiating LTBI treatment, and not-completing treatment. RESULTS Proportions of visiting clinics and initiating and completing treatment in HCWs were 54.9%, 38.5%, and 32.0%, respectively. Despite of less likelihood of visiting clinics and initiating LTBI treatment, older age ≥ 65 years were more likely to complete treatment (adjusted relative risk [aRR], 0.80; 95% confidence interval [CI], 0.64-0.99), compared to young age < 35 years. Compared to nurses, doctors were less likely to visit clinic; however, were more likely to initiate treatment (aRR, 0.88; 95% CI, 0.81-0.96). Those who visited public health centers were associated with not-initiating treatment (aRR, 1.34; 95% CI, 1.29-1.40). When treated at private hospitals, 9-month isoniazid monotherapy was less likely to complete treatment, compared to 3-month isoniazid and rifampicin combination therapy (aRR, 1.33; 95% CI, 1.16-1.53). CONCLUSION Among employees of medical institutions with LTBI, only one third completed treatment. Age, occupation, treatment center, and initial regimen were significantly related to LTBI treatment performance indicators. Rifampicin-based short treatment regimens were effective under standard of care.

Abstract
Despite the importance of latent tuberculosis infection (LTBI) treatment and management in healthcare workers (HCWs), only a few studies have provided a comprehensive review of factors associated with the success rate of each stage of the LTBI treatment, as well as strategies to improve treatment adherence. This study investigated factors and determinants of patient losses at each stage of the entire cascade of LTBI in HCWs. Studies were extracted from PubMed, EBSCOhost, EMBASE, Cochrane Library, and ScienceDirect. Our study found poor completion rates of LTBI treatment in HCWs. The main reason for not visiting the outpatient clinic or not accepting treatment was related to the demographic characteristics, whereas adverse drug effects were the main reason for treatment discontinuation. These findings suggest that tailored interventions must be developed to improve the success rate at each stage of the LTBI treatment in HCWs.

Abstract
Tuberculosis (TB) remains a serious public health problem in Korea. Korea has the highest incidence rate (59 per 100,000 population) and the second-highest TB mortality rate (four per 100,000 population) among Organisation for Economic Cooperation and Development member countries. However, some progress has been made in TB control over the past decade. The notification rate of new TB cases has been gradually decreasing since reaching its highest rate in 2011 (78.9 per 100,000 population). In 2019, the notification rate of new TB cases was 46.4 per 100,000 population, with a reduction of 9.9% from the 2018 rate. Additionally, the number of multidrug-resistant TB cases decreased from 618 in 2018 to 580 in 2019. This progress is thought the result of various TB control programs including a TB public–private mix model, insurance coverage for TB management, and a contact investigation program. Despite the progress made, new challenges have also emerged. The predominant challenges lie in the relatively increasing burden of TB in the vulnerable population (aging, socio-economically vulnerable, and foreign-born population), the implementation of latent TB infection management, and the high rate of multidrug-resistant TB. Since 2019, the Korean government has been implementing the “Midterm strategies to strengthen TB prevention and management” based on the 2nd National Strategic Plan for Tuberculosis Control (2018-2022). This program will be a turning point of TB control in Korea. The results produced in 2023 is expected to be favorable.

Abstract
More than one in two healthcare workers (HCWs) in developing countries have latent tuberculosis infection (LTBI), an asymptomatic condition signifying persistent tubercular infection in absence of disease. OBJECTIVE to evaluate the physician attitude towards LTBI preventive therapy and their perspectives regarding the potential expansion of latent TB management under the RNTCP. MATERIAL AND METHODS We conducted a cross-sectional analysis among 60 participants of a continuing medical education program during October' 2019 in a medical college in Delhi, India. RESULTS We enrolled a total of 30 medical officers, 15 resident doctors and 15 medical interns, comprising 27 (45%) males and 33 (55%) females. Only 9 (15%) participants were aware of existing RNTCP guidelines for programmatic management of LTBI. The median (IQR) self-rated willingness of the participants in receiving treatment for LTBI after confirmation of diagnosis on a 10 point continuous rating scale was 6 (5.8). The principal reason attributed to the treatment hesitancy were concerns over drug side effects 19 (31.7%), emergence of drug resistance 11 (18.3%) and the likelihood of reinfection 4 (6.7%). Support for expansion of preventive therapy among household TB contacts was varied, with maximum (41.2%) participants wanting it only for the comorbid patients. CONCLUSION LTBI preventive treatment is associated with considerable side effects and lack of long-term benefits by a majority of Indian physicians despite significant personal health concerns in treating pulmonary TB cases.

Abstract
Poor adherence to medication can lead to treatment failure in healthcare workers (HWCs) with latent tuberculosis infection (LTBI) who are at high risk of developing active tuberculosis. However, the factors associated with non-completion of nine-month LTBI treatment with isoniazid (9 H) have not been well studied. We investigated the completion rate and factors affecting adherence to LTBI treatment with 9 H among HCWs. A prospective cohort study of 114 HCWs who were diagnosed with LTBI by QuantiFERON-TB Gold In-Tube tests were performed in a single university hospital between June 2016 and December 2017. All patients received the 9 H LTBI treatment. At each visit, treatment adherence and development of adverse reactions to isoniazid were evaluated via a standard questionnaire. To evaluate the impact of the severity of hepatotoxicity on non-completion of LTBI treatment, we classified hepatotoxicity into two groups: severe hepatotoxicity was defined as alanine aminotransferase >3.0 times the upper normal limit (UNL) with symptoms or = 5.0 times the UNL. Mild hepatotoxicity was defined as alanine aminotransferase>UNL, but not meet the definition of severe hepatotoxicity. Overall, 71 HCWs (62.3%) completed LTBI treatment with 9 H while 43 HCWs (37.7%) discontinued their treatment. Most discontinuation (81.4%, 35/43) occurred during the first three months of treatment. There were no significant differences in age, sex, occupation, or comorbidities between the HCWs who completed and those who discontinued LTBI treatment. However, HCWs who discontinued LTBI treatment had more hepatotoxicity than those who completed treatment (44.2% vs. 11.3%, P < 0.001). Cox proportional hazard analysis revealed that hepatotoxicity is the only factor significantly associated with discontinuation of 9 H LTBI treatment (unadjusted HR = 2.89, 95% CI = 1.62–5.46). In multivariable analysis, not only severe hepatotoxicity (adjusted HR = 7.99, 95% CI = 3.05–20.94) but also mild hepatotoxicity was significantly associated with discontinuation of LTBI treatment (adjusted HR = 2.34, 95% CI = 1.05–5.21). The completion rate of 9 H LTBI treatment was 62.3% among HCWs. While age, sex, occupation, and pretreatment comorbidities were not associated with treatment completion, isoniazid-induced hepatotoxicity significantly affected adherence.

Abstract
Objective Healthcare workers (HCWs) are one of the target groups for systematic testing and treatment of latent tuberculosis infection (LTBI) in a setting of low TB incidence. We performed this study to describe the testing of HCWs for LTBI and analyse the acceptance and completion of treatment of LTBI. Methods This retrospective cohort study was conducted in four university-affiliated hospitals between January 1 and December 31, 2018. HCWs with positive interferon-gamma release assay (IGRA) during LTBI screening were analysed. We assessed the acceptance and completion of LTBI treatment. Results Overall, 893 HCWs were IGRA positive. Among them, 609 HCWs visited the clinic for evaluation of LTBI. Of 609 HCWs who were evaluated, 302 (49.6%) were offered treatment for LTBI. The proportion of acceptance for treatment was 64.5% (195 of 302 HCWs). The treatment course was completed by 143 of 195 HCWs (73.3%). Three months of isoniazid and rifampin (3HR) was used in 137 HCWs (70.3%) and 4 months of rifampin (4R) in 58 (29.7%). 72 HCWs (36.9%) experienced at least one adverse drug events, but there was no different characteristics between completer and non-completer. Conclusion The acceptance and completion of LTBI treatment were unsatisfactory. Subjective perspective regarding obstacles to treatment of LTBI needs to be explored to increase compliance to LTBI treatment.

Abstract
INTRODUCTION There are insufficient data on the treatment of latent tuberculosis infection (LTBI) in elderly patients. We investigated the completion rate of treatment in elderly LTBI patients. METHODS A retrospective multicentre study was conducted at five university hospitals in South Korea. We reviewed the electronic medical records of patients aged 65 years and older who were diagnosed with LTBI via positive interferon-gamma release assay results between January 2016 and December 2018. Treatment completion was defined as ingestion of more than 80% of all prescribed medications without loss to follow-up. RESULTS During the study period, 127 LTBI patients aged 65 years and older visited outpatient department. Among them, 77 patients aged 65-78 years (median age, 69 years [interquartile range, 66-71 years]) who received LTBI treatment were analysed. Common reasons for IGRA testing in elderly patients were health-care worker (n = 33, 42.9%) and household contact with infectious TB patients (n = 18, 23.4%). The overall completion rate of LTBI treatment was 83.1% (n = 64), and the completion rate of 3-month isoniazid plus rifampin regimen was 88.4%. Adverse effects were reported in 23 patients (29.9%), and an increase in aminotransferase level was the most common adverse effect (n = 11, 14.3%). Three patients (3.9%) with the adverse effect discontinued treatment and 10 (13.0%) patients were lost to follow-up. CONCLUSIONS LTBI treatment in patients aged 65-78 years was relatively well tolerated. In LTBI treatment in elderly patients, the majority of discontinuation of treatment was due to loss to follow-up rather than adverse effects of anti-TB medications.
