Epidemiological Situation

The spread of multidrug-resistant and extensively drug-resistant tuberculosis (MDR and XDR) requires the search and implementation of not only new diagnostic methods, but also innovations in the treatment of the disease. Aim. The assessment of current treatment options for multidrug-resistant tuberculosis in different countries. Materials and Methods. There was carried out the content analysis of the official sources of 24 countries concerning the drugs that had been registered at these countries and recommended by the World Health Organization for the treatment of multidrug-resistant tuberculosis and put into circulation from 2000 to 2020: linezolid, bedaquiline, delamanid, clofazimine (as of 07.2020). The data were compared with the characteristics of the epidemiological situation in the country. Results. There was developed a six-digit classification by the following criteria: the presence of international nonproprietary names for drugs; the availability and range of dosage forms; the number of drugs subject to all dosage forms, dosages, pharmaceutical forms and units of packaging; the presence in the domestic market of the original product; the time of registration of drugs in the specified territory; the level of multi-drug resistance of the pathogen in the country per 100,000 population. Among the countries with the highest market coverage with a low (up to 0.5 per 100 thousand) level of multidrug resistance, a large share falls on European countries. As for a number of African States, there may be a threat of spreading the disease taking into account the epidemiological situation for multidrug-resistant tuberculosis and with only linezolid registered. The list of countries with a level of the same indicator above 15 per 100,000 population includes Russia and Namibia with radically different market characteristics. If Russia possesses the entire available range of medicines with the number of nomenclature items above 200, then Namibia has no more than 10 linezolid preparations registered only in tablet form. The main supplier of innovative products in the field of tuberculosis control is the Asia-Pacific region. Сonclusion. It is defined that the characteristics of the drug market differ significantly depending on the economic development of states and are determined by the indicator of the disease burden. Success in the tuberculosis control is impossible without the active development of the pharmaceutical industry and the replenishment of the market with innovative products.

The Cost

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.

The World Health Organization uses a Grading of Recommendations Assessment, Development, and Evaluation process to make recommendations for treating multidrug-resistant tuberculosis. Even with this standardized approach, there have been discrepancies between recommendations for newer drugs such as bedaquiline and delamanid and the shorter regimen. This may be because newer drugs are novel chemical entities and may merit closer scrutiny. Here, we explore the problematic nature of this supposition, arguing that although the newer drugs have been used in fewer individuals, they may have more robust efficacy and safety data than many of the second-line drugs used in the shorter regimen.

ABSTRACTTo investigate the molecular characterization of multidrug-resistant tuberculosis (MDR-TB) isolates from China and the association of specific mutations conferring drug resistance with strains of different genotypes, we performed spoligotyping and sequenced nine loci (katG,inhA, theoxyR-ahpCintergenic region,rpoB,tlyA,eis,rrs,gyrA, andgyrB) for 128 MDR-TB isolates. Our results showed that 108 isolates (84.4%) were Beijing family strains, 64 (59.3%) of which were identified as modern Beijing strains. Compared with the phenotypic data, the sensitivity and specificity of DNA sequencing were 89.1% and 100.0%, respectively, for isoniazid (INH) resistance, 93.8% and 100.0% for rifampin (RIF) resistance, 60.0% and 99.4% for capreomycin (CAP) resistance, 84.6% and 99.4% for kanamycin (KAN) resistance, and 90.0% and 100.0% for ofloxacin (OFX) resistance. The most prevalent mutations among the MDR-TB isolates werekatG315,inhA15,rpoB531, -526, and -516,rrs1401,eis-10, andgyrA94, -90, and -91. Furthermore, there was no association between specific resistance-conferring mutations and the strain genotype. These findings will be helpful for the establishment of rapid molecular diagnostic methods to be implemented in China.

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.

The World Health Organization estimates that 10 million new cases of tuberculosis (TB) occurred worldwide in 2017, of which 600,000 were rifampicin or multidrug-resistant (RR/MDR) TB. Modelling estimates suggest that 32,000 new cases of MDR-TB occur in children annually, but only a fraction of these are correctly diagnosed and treated. Accurately diagnosing TB in children, who usually have paucibacillary disease, and implementing effective TB prevention and treatment programmes in resource-limited settings remain major challenges. In light of the underappreciated RR/MDR-TB burden in children, and the lack of paediatric data on newer drugs for TB prevention and treatment, we present an overview of new and repurposed TB drugs, describing the available evidence for safety and efficacy in children to assist clinical care and decision-making.

ABSTRACT The prolonged use of injectable agents in a regimen for the treatment of multidrug-resistant tuberculosis (MDR-TB) is recommended by the World Health Organization, despite its association with ototoxicity and nephrotoxicity. We undertook this study to look at the relative adverse effects of capreomycin and amikacin. We reviewed the case notes of 100 consecutive patients treated at four MDR-TB treatment centers in the United Kingdom. The median total duration of treatment with an injectable agent was 178 days (interquartile range [IQR], 109 to 192 days; n = 73) for those with MDR-TB, 179 days (IQR, 104 to 192 days; n = 12) for those with MDR-TB plus fluoroquinolone resistance, and 558 days (IQR, 324 to 735 days; n = 8) for those with extensively drug-resistant tuberculosis (XDR-TB). Injectable use was longer for those started with capreomycin (183 days; IQR, 123 to 197 days) than those started with amikacin (119 days; IQR, 83 to 177 days) (P = 0.002). Excluding patients with XDR-TB, 51 of 85 (60%) patients were treated with an injectable for over 6 months and 12 of 85 (14%) were treated with an injectable for over 8 months. Forty percent of all patients discontinued the injectable due to hearing loss. Fifty-five percent of patients experienced ototoxicity, which was 5 times (hazard ratio [HR], 5.2; 95% confidence interval [CI], 1.2 to 22.6; P = 0.03) more likely to occur in those started on amikacin than in those treated with capreomycin only. Amikacin was associated with less hypokalemia than capreomycin (odds ratio, 0.28; 95% CI, 0.11 to 0.72), with 5 of 37 (14%) patients stopping capreomycin due to recurrent electrolyte loss. There was no difference in the number of patients experiencing a rise in the creatinine level of >1.5 times the baseline level. Hearing loss is frequent in this cohort, though its incidence is significantly lower in those starting capreomycin, which should be given greater consideration as a first-line agent.

  The World Health Organization (WHO) recommended microscopic AFB smear examination and culture as follow-ups to the response of MDR TB therapy. Analyzed the results of microscopic AFB smear and culture conversion as well as treatment outcome in Multidrug-Resistant Tuberculosis (MDR-TB) patients with and without Diabetes Mellitus (DM). This is a retrospective study involved 70 MDR-TB patients with (27 patients) with DM and without DM (43 patients) who had microscopic AFB smear and culture results at the start of the follow-up therapy. This research was conducted at Labuang Baji Regional Public Hospital, Makassar, from June to July 2019, used medical records of MDR-TB patients the period of June 2016 to December 2017. The results showed that 52 out of 70 MDR-TB patients had microscopic AFB smear and culture conversion in MDR-TB with DM (21 patients) and without DM (31 patients). The duration of microscopic AFB smear conversion in MDR TB patients with DM (3.33±0.54 months) was longer than patients without DM (2.07±0.05 months), p=0.001. While in culture conversion, there was no significant difference between MDR-TB with DM (1.28±0.64 months) and without DM (1.25±0.59), p=0.648. The recovery outcome between MDR-TB with (48.1%) and without DM (48.8%) was not significantly different. However, the output of treatment failure was greater in DM (11.2%) than without DM (2.3%), although statistically, there was no significant difference (p=0.568). Multidrug-resistant tuberculosis patients with DM experienced slower microscopic AFB smear conversion than MDR-TB patients without DM. However, in culture, there was no significant difference in the conversion period between the two groups. MDR-TB patients, both of with and without DM, had the same chance of recovery.
