One fourth of the global population has been infected with Mycobacterium tuberculosis, and about 5%-10% of the infected individuals with latent tuberculosis infection (LTBI) will convert to active tuberculosis (ATB). Correct diagnosis and treatment of LTBI are important in ending the tuberculosis epidemic. Current methods for diagnosing LTBI, such as tuberculin skin test (TST) and interferon-γ release assay (IGRA), have limitations. Some novel biomarkers, such as transcriptome derived host genes in peripheral blood cells, will help to distinguish LTBI from ATB. More emphasis should be placed on surveillance in high-risk groups, including patients with HIV infection, those using biological agents, organ transplant recipients and those in close contact with ATB patients. For those with LTBI, treatment should be based on the risk of progression to ATB and the potential benefit. Prophylactic LTBI regimens include isoniazid monotherapy for 6 or 9 months, rifampicin monotherapy for 4 months, weekly rifapentine plus isoniazid for 3 months (3HP regimen) and daily rifampicin plus isoniazid for 3 months (3HR regimen). The success of the one month rifapentine plus isoniazid daily regimen (1HP regimen) suggests the feasibility of an ultra-short treatment strategy although its efficacy needs further assessment. Prophylactic treatment of LTBI in close contact with MDR-TB patients is another challenge, and the regimens include new anti-tuberculosis drugs such as bedaquiline, delamanid, fluoroquinolone and their combinations, which should be carefully evaluated. This article summarizes the current status of diagnosis and treatment of LTBI and its future development direction.

Causative factors of multi-drug resistance tuberculosis (MDR-TB) were analyzed from iatrogenic angles, patients themselves, and society. Reviewed was the development of treatment strategies for MDR-TB from directly observed treatment short-course (DOTS) to DOTS-Plus. The history of Chinese medicine (CM) fighting TB and characteristics at the present stage were also analyzed. Authors pointed out that CM pays attention not only to killing pathogens and confirms the necessity of getting rid of pathogens, but also to cascade response caused by pathogens. It also regards the occurrence and development of MDR-TB as a whole by combining patients' conditions, climatic, geographic, psychological, and social factors. Authors believed that therapeutic principles under guidance of CM holistic view are of positive significance and inspiration in treating MDR-TB, and emphasized holistic view as basic strategies for treating MDR-TB, but not a single countermeasure.

Multidrug-resistant tuberculosis (MDR-TB) has become one of the major challenges in the global tuberculosis (TB) control.Despite years of efforts on MDR-TB control,the treatment success rates in China have increased slowly,which indicates possible deficiencies in the management of prevention and control work.Therefore,it is necessary to analyze the current status of MDR-TB prevention and treatment based on the patient pathway.This review summarizes the current drop-out situation of MDR-TB patients in the diagnosis and treatment pathway and the factors affecting patients' outcomes in the whole pathway,so as to provide a scientific reference for the prevention and control of MDR-TB.

OBJECTIVEThis study aimed to review the available literatures on control of latent tuberculosis (TB) infection and propose a new control strategy to shorten the course of TB chemotherapy.

DATA SOURCESThe data used in this review were mainly obtained from articles listed in PubMed. The search terms were "therapy (treatment) of tuberculosis," "therapy (treatment) of latent TB infection," and "vaccine of TB."

STUDY SELECTIONArticles regarding treatment and vaccine of TB were selected and reviewed.

RESULTSThe most crucial reason causing the prolonged course of TB chemotherapy is the dormant state of Mycobacterium tuberculosis (M. tuberculosis). Nevertheless, there are, to date, no effective drugs that can directly kill the dormant cells of M. tuberculosis in clinical therapy. In accordance with the growth cycle of dormant M. tuberculosis in the body, the methods for controlling dormant M. tuberculosis include direct killing with drugs, prevention of dormant M. tuberculosis resuscitation with vaccines, and resuscitating dormant M. tuberculosis with preparations or drugs and then thoroughly killing these resuscitated M. tuberculosis by using anti-TB therapy.

CONCLUSIONSThe comprehensive analysis of the above three methods suggests that the drugs directly killing dormant cells are in clinical trials, TMC207 is the most beneficial for controlling TB. Because the side effect of vaccines is less and their action period is long, prevention of dormant cells resuscitation with vaccines is promising. The last control method makes it probable that when a huge number of active cells of M. tuberculosis have been killed and eradicated after 1-month short chemotherapy, only a strong short-term subsequent chemotherapy can completely kill and eradicate the remaining M. tuberculosis. This control strategy is expected to significantly shorten the course of TB chemotherapy and bring a new change and breakthrough in TB treatment.
