Inflammatory reconstitution of immune syndrome (IRIS) is an immunological reaction characterized by recurrent or new inflammatory signs of tuberculosis (TB) that occur shortly after antiretroviral therapy (ART) in 18 % of patients infected with human immunodeficiency virus (HIV). Features of the syndrome include recurrent symptoms: fever, lymphadenitis and the spread of pulmonary infiltrates on radiography. Low CD4 levels and a short interval between the onset of ART increase the risk of developing TB-associated immune system recovery syndrome. Clinical trials show that early onset of ART results in higher survival rates than ART initiated approximately 8 weeks after the start of TB treatment in patients with a CD4 count of 50 cells/μl. These findings are in line with the recommendations of the World Health Organization, which emphasize the acceleration of the onset of ART in patients with TB and low CD4 levels. However, despite the advantage of survival, early administration of ART more than increases the risk of developing IRIS associated with TB. There is no evidence-based strategy for the prevention of IRIS associated with TB. Studies evaluating adjuvant glucocorticoids for the treatment of various forms of TB have shown reduced mortality among TB patients and fewer complications among TB patients. The aim of the study was to evaluate the prophylactic use of prednisolone to safely reduce the incidence of TB-associated IRIS in patients with multidrug resistant TB (MDR TB) is at high risk of developing the syndrome. We observed HIV-infected patients who started ART (and had not previously received ART) and started TB treatment within 30 days before the start of ART and had a CD4 count of 50 cells/μl. Patients received either standard therapy with prednisolone (at a dose of 40 mg per day for 14 days, then 20 mg per day for 14 days) or only standard therapy without prednisolone. The main endpoint was the development of TB associated with TB within 12 weeks after the onset of ART. Among the 64 patients observed, the mean age was 36 years, 60 % were male, and 73 % had microbiologically confirmed TB; the median amount of CD4 was 49 cells/μl, and the median viral load was 5.5 log 10 copies/μl. Patients were divided into 2 groups. Each group included 32 patients with MDR TB / HIV co-infection. IRIS associated with TB was diagnosed in 10 patients (31.25 %) in the prednisolone group and in 17 (53.14 %) in the control group (p<001). Thus, prednisolone treatment of co-infected patients with MDR TB for the first 4 weeks after the onset of HIV-related ART resulted in a lower incidence of TB-associated IRIS than in the control group, with no evidence of an increased risk of severe infections or cancer.

SETTING: The World Health Organization (WHO) recommends that multidrug-resistant tuberculosis (MDR-TB) treatment should be managed in collaboration with multidisciplinary advisory committees (consilia). A formal national Consilium has been established in France since 2005 to provide a centralised advisory service for clinicians managing MDR-TB and extensively drug-resistant (XDR-TB) cases.OBJECTIVE: Review the activity of the French TB Consilium since its establishment.DESIGN: Retrospective description and analysis of the activity of the French TB Consilium.RESULTS: Between 2005 and 2016, 786 TB cases or contacts of TB cases were presented at the French TB Consilium, including respectively 42% and 79% of all the MDR-TB and XDR-TB cases notified in France during this period. Treatment regimens including bedaquiline and/or delamanid were recommended for 42% of the cases presented at the French TB Consilium since 2009. Patients were more likely to be presented at the French TB Consilium if they were born in the WHO Europe Region, had XDR-TB, were diagnosed in the Paris region, or had resistance to additional drugs than those defining XDR-TB.CONCLUSION: The French TB Consilium helped supervise appropriate management of MDR/XDR-TB cases and facilitated implementation of new drugs for MDR/XDR-TB treatment.

Tuberculosis (TB) is one of the top 10 leading causes of morbidity and mortality worldwide [1]. In 2017, approximately 10 million people were infected with TB and 1.3 million patients faced mortality [1]. Patients with active TB can infect up to 10–15 people over a year. There is a greater risk of transmission in overcrowded areas with limited air ventilation including large family units, prisons and slums [1, 2]. Without proper diagnosis and treatment, roughly 45% of non-HIV positive TB patients face mortality [1]. With the help of global organizations and national TB treatment and control programmes, the global incidence of TB is declining by approximately 2% each year [1]. The World Health Organization (WHO) TB-strategy aims to end the TB epidemic and encourages partners to fund national TB programmes to improve diagnosis and treatment of TB. The goal is to ultimately decrease death rates by 90% and decrease incidence rates by 80% [1]. To achieve these goals, the decline in TB incidence needs to reach approximately 4–5% per year [1]. The WHO 2018 TB report identified multidrug resistant TB (MDR-TB) as the leading factor hindering that goal [1]. The incidence and spread of MDR-TB has drastically increased, where approximately 558 000 new cases of MDR-TB were diagnosed in 2017 causing more than 230 000 deaths globally [1]. MDR-TB is identified by resistance to the two most powerful anti-TB treatment drugs including isoniazid and rifampicin [3]. Patients with MDR-TB are required to start second-line anti-TB drugs (SLDs), which are limited, expensive, less effective and more toxic [1,2]. Therapy duration is one of the major limitations of second-line treatments, which may require up to two years of consistent use. Since TB affects mostly developing countries, long treatment durations and associated costs become a major challenge. In 2015, 15% of new TB cases were reported as MDR-TB, which drastically increased to 24% by 2017 [1]. Even with significant improvements in molecular tests and diagnostic methods, MDR-TB is still on the rise where the success rate of treatments is between 50 and 60% [1]. Additional characteristics including socioeconomic and sociocultural factors need to be considered when targeting and treating patients with MDR-TB.

Introduction: World Health Organization recommendations of bidirectional screening for tuberculosis (TB) and diabetes have been met with varying levels of uptake by national TB programs in resource-limited settings. Methodology: Kibong’oto Infectious Diseases Hospital (KIDH) is a referral hospital for TB from northern Tanzania, and the national referral hospital for multidrug-resistant (MDR)-TB. Glycated hemoglobin (HgbA1c) testing was done on patients admitted to KIDH for newly diagnosed TB, retreatment TB, and MDR-TB, to determine the point prevalence of diabetes (HgbA1c ≥ 6.5%) and prediabetes (HgbA1c 5.7%–6.4%). Results: Of 148 patients hospitalized at KIDH over a single week, 59 (38%) had no prior TB treatment, 22 (15%) were retreatment cases, and 69 (47%) had MDR-TB. Only 3 (2%) had a known history of diabetes. A total of 144 (97%) had successful screening, of which 110 (77%) had an HgbA1c ≤ 5.6%, 28 (19%) had ≥ 5.7 < 6.5, and 6 (4%) had ≥ 6.5. Comparing subjects with prediabetes or diabetes to those with normal A1c levels, retreatment patients were significantly more likely to have a A1c ≥ 5.7% (odds ratio: 3.2, 95% CI: 1.2–9.0; p = 0.02) compared to those without prior TB treatment. No retreatment case was a known diabetic, thus the number needed to screen to diagnose one new case of diabetes among retreatment cases was 11. Conclusions: Diabetes prevalence by HgbA1c was less common than expected, but higher HgA1c values were significantly more frequent among retreatment cases, allowing for a rational, resource-conscious screening approach.

Treatment of multidrug-resistant tuberculosis (MDR-TB) with second-line injectable drugs may result in an electrolyte imbalance. This retrospective study was performed to compare and evaluate the effect of kanamycin and capreomycin on serum potassium, calcium, and magnesium in the first and second month treatment at a tertiary, top-referral hospital in Bandung, Indonesia. Data from 84 subjects with complete medical records of at least serum potassium during either kanamycin-based or capreomycin-based treatment were retrieved from the institutional database. Among these, 53 subjects had complete serum calcium data and 53 subjects had complete serum magnesium data. After the first month of MDR-TB treatment, there was a significant decrease in mean serum potassium (4.0 ± 0.4 mEq/L to 3.7 ± 0.5 mEq/L, p<0.003) in the kanamycin-based group and (4.1 ± 0.5 mEq/L to 3.2 ± 0.6 mEq/L, p<0.001) in the capreomycin-based group. Serum potassium levels were significantly lower in the capreomycin-based group than in the kanamycin-based group (3.2 ± 0.6 mEq/L vs 3.7 ± 0.5 mEq/L, p<0.001). The incidence of hospitalization and requirement for a change in the treatment regimen due to electrolyte imbalances were higher in the capreomycin-based group. No previous longitudinal study has evaluated serum potassium, magnesium, and calcium from the first month of MDR-TB treatment with either kanamycin-based or capreomycin-based regimens. Our findings emphasize the importance of routine monitoring of serum potassium, magnesium, and calcium during MDR-TB treatment, and that more attention should be paid when treatment is given using the capreomycin-based regimen. Moreover, our study supported the 2018 World Health Organization treatment guideline recommendations for removal of kanamycin and capreomycin from the MDR-TB regimens.

SETTING: In 2005, in response to the increasing prevalence of rifampicin-resistant tuberculosis (RR-TB) and poor treatment outcomes, Rwanda initiated the programmatic management of RR-TB, including expanded access to systematic rifampicin drug susceptibility testing (DST) and standardised treatment.OBJECTIVE: To describe trends in diagnostic and treatment delays and estimate their effect on RR-TB mortality.DESIGN: Retrospective analysis of individual-level data including 748 (85.4%) of 876 patients diagnosed with RR-TB notified to the World Health Organization between 1 July 2005 and 31 December 2016 in Rwanda. Logistic regression was used to estimate the effect of diagnostic and therapeutic delays on RR-TB mortality.RESULTS: Between 2006 and 2016, the median diagnostic delay significantly decreased from 88 days to 1 day, and the therapeutic delay from 76 days to 3 days. Simultaneously, RR-TB mortality significantly decreased from 30.8% in 2006 to 6.9% in 2016. Total delay in starting multidrug-resistant TB (MDR-TB) treatment of more than 100 days was associated with more than two-fold higher odds for dying. When delays were long, empirical RR-TB treatment initiation was associated with a lower mortality.CONCLUSION: The reduction of diagnostic and treatment delays reduced RR-TB mortality. We anticipate that universal testing for RR-TB, short diagnostic and therapeutic delays and effective standardised MDR-TB treatment will further decrease RR-TB mortality in Rwanda.

IntroductionAccording to the World Health Organization, there were approximately 0.5 million new cases of rifampicin-resistant tuberculosis in 2018, of which 78 percent were multidrug-resistant tuberculosis (MDR-TB), and China has one of the largest shares of the global burden (14%). In recent years, the Chinese government has made progress in TB control and prevention, but for MDR-TB, treatment options are still limited and expensive, and novel drugs are not always available. This research aims to evaluate the cost-effectiveness of adding bedaquiline to a background regimen (BR) of drugs for MDR-TB treatment in China, and to provide evidence for government to improve public health policies.MethodsA cohort-based Markov model was developed to evaluate the incremental cost-effectiveness ratio (ICER) of bedaquiline plus BR (BBR) versus BR alone in MDR-TB treatment, over a 10-year time horizon. Data were sourced from a phase II clinical trial, real-world data in China, published literature, and expert opinion. Outcomes were evaluated in quality-adjusted life years (QALYs) and life-years gained (LYG). The discount rate was 3.5%. Probabilistic and deterministic sensitivity analyses were conducted.ResultsThe discounted costs per person for BBR was CNY 135,706 [USD 19,172], compared with CNY 92,465 [USD 13,063] for BR. The discounted utility per person for BBR was also higher than that for BR (3.943 QALYs versus 3.193 QALYs). The ICER of BBR was CNY 58,096 [USD 8,208]/QALY, which was lower than the willingness-to-pay threshold of CNY 212,676 [USD 30,046] (three-times the gross domestic product per capita). Therefore, BBR was considered to be cost-effective. The sensitivity analysis confirmed the robustness of the results. BBR remained cost-effective in the sensitivity analysis, with a 77.2 percent probability of being cost-effective versus BR.ConclusionsIn China, bedaquiline is not included in the National Reimbursement Medicine List, which results in a heavy financial burden for MDR-TB patients. From this study, BBR was cost-effective by significantly reducing time to sputum culture conversion and increasing QALYs and LYGs, which offset the higher drug costs.

Relatively little is known about the efficacy and safety of the programmatic use of bedaquiline and delamanid in multidrug-resistant tuberculosis (MDR-TB) treatment.This study evaluated 61 patients with MDR-TB treated with bedaquiline (n=39), delamanid (n=11) or both, either sequentially (n=10) or in coadministration (n=1), for >1 month, combined with a World Health Organization-recommended regimen.Of these, 49 (80.3%) were male and 12 (19.7%) were female. The median (interquartile range (IQR)) age was 53 (38.5–61.0) years. 42 (68.9%) patients had fluoroquinolone-resistant MDR-TB and 16 (26.2%) had extensively drug-resistant TB. The median (IQR) duration of treatment with bedaquiline and/or delamanid was 168 (166.5–196.5) days, with 33 (54.1%) receiving linezolid for a median (IQR) of 673 (171–736) days. Of the 55 patients with positive sputum cultures at the start of bedaquiline and/or delamanid treatment, 39 (70.9%) achieved sputum culture conversion within a median of 119 days. Treatment was halted in four patients (6.6%) because of prolonged Fridericia's corrected QT interval.Bedaquiline and delamanid were effective and safe for treating MDR-TB, with initial evidence of sequential administration of these two drugs as a viable treatment strategy for patients when an adequate treatment regimen cannot be constructed.

Abstract Background Globally, refugee populations face an increased risk for tuberculosis (TB) due to malnutrition, overcrowding, and poor living conditions. Compared with the general Indian population, Tibetan refugees in India display a higher incidence rate of both TB and multidrug-resistant TB (MDR-TB). The high incidence of MDR-TB in younger population is a serious public health concern. Methods We retrospectively reviewed the medical records of patients with MDR-TB treated from January 2010 to December 2013 in Tibetan Delek Hospital, which is the center of TB control among Tibetan refugees. Patients were classified into either new cases (supposed infection by exposure to MDR-TB) or previously treated MDR-TB cases (suspected acquirement of MDR-TB through anti-TB treatment or by MDR-TB exposure after treatment). We compared patients’ age, sex, birthplace, residence type, occupation, contact history, and treatment outcome. Results Of 749 patients with TB, we enrolled 134 patients with MDR-TB [median age, 26 (interquartile range: 22–35) years; males, 55%]. The Tibetan ethnicity comprised 96% of the study population, whereas Indians (trans-Himalayan) comprised 4%. The birthplace was Tibet for 22% patients, India for 75%, and Nepal for 2%. New MDR-TB cases were 28% and previously treated MDR-TB cases were 72%. Failure was observed in 42% patients and cured and completed in 54% patients, during their previous TB treatment. The median age was significantly lower in new cases than in previously treated MDR-TB cases (24 vs. 28.5 years; P &lt; 0.01). Tibet was the birthplace of 34% new cases and 18% in previously treated cases (P = 0.04). The residence was of the congregated type in 58% of new cases and 30% in previously treated MDR-TB cases (P = 0.01). The occupation was “student” and “unemployed” in 58% and 8% in new cases and 33% and 24% in previously treated cases, respectively (P = 0.03). Contact history with TB type and treatment outcome were not considerably different, although the rates of cured and completed were high in both new (82%) and previously treated (84%) MDR-TB cases. Conclusion This study shows that new MDR-TB correlates with younger age, birth in Tibet, congregated residence, and student occupation. Targeting the above-listed characteristics could be effective in further reducing the MDR-TB transmission among Tibetan refugees in India. Disclosures All authors: No reported disclosures.

IntroductionChina bears a considerably high burden of multidrug-resistant tuberculosis (MDR-TB). Second-line anti-TB drugs are urgently needed yet domestic MDR-TB drugs are expensive and lack policy support. Patients’ living conditions are closely related to the drug affordability. The national TB prevention programs should play a critical role. The purpose of this study is to measure the cost of treating MDR-TB patients under different treatment schemes and price sources. The results of this study are expected to inform the relevant drug protection policies and provide inputs for further cost-effectiveness analyses.MethodsBased on the treatment plan of China's Multidrug-Resistant Pulmonary Tuberculosis Clinical Path (2012 edition) and the World Health Organization (WHO) Drug-Resistant Tuberculosis Treatment Guide (2018 edition), the treatment costs of MDR-TB were measured under different scenarios. Catastrophic health expenditure was then calculated if the treatment cost exceeds 40 percent of the household's non-subsistence income. National, rural and disposable income per capita in 2018, were used to represent Chinese patients’ affordability.ResultsUnder varied treatment schemes and market price sources in China, the total costs for MDR-TB patients range from 19,401 to 126,703 CNY [2,853 to 18,633 USD] per person. Under current prices, all treatment schemes recommended by the WHO will incur catastrophic costs for Chinese MDR-TB patients. Significant differences were found between rural and urban areas as 52.8 percent of the treatment listed in the 2012 China Guideline would lead to catastrophic cost for rural patients but not urban ones.ConclusionsOur study concludes that the domestic drugs are more expensive than the international purchase price and the treatment of MDR-TB imposes substantial economic burden on patients, especially in the rural areas. The results of the study also indicate that it is urgent for the state to emphasize government responsibility and initiate centralized procurement for price negotiations to reduce the market price of MDR-TB drugs. The urban-rural gap should also be addressed in the design of future policies to ensure the drug affordability for all patients in need.
