The multidrug-resistant tuberculosis (MDR-TB) remains a significant public health burden in term of the successful TB treatment because of the lack awareness of TB drugs administration. Patients infected with MDR-TB are resistant to isoniazid (INH) and rifampicin (RMP) due to genotypic mutation, thus could not adequately treated by the first-line regimen standards. The management of MDR-TB using Short-Term Regimen (STR) is a crucial topic to be discussed due to low success rate of conventional therapy and its long duration. This systematic review aims to further examine the effectiveness and safety of STR to manage MDR-TB. In this systematic review, various cohort studies were searched using standardized Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA). The keywords were arranged based on Problem, Intervention, Comparison, and Outcome (PICO). Key terms consisted of multidrug-resistant tuberculosis and short regimen therapy. Seven cohort studies were selected from 314 studies. STR has better therapeutic efficacy and shorter duration than the 2011 WHO regimen for MDR-TB with therapy success rates for each study above 50%. The most effective regimen according to studies in this review is kanamycin-high dose isoniazid-clofazimine-ethambutol-prothionamide- pyrazinamidegatifloxacin (KM-INH-CFZ-EMB-PTH-PZA-GFX) in the intensive phase for 4 months and clofazimine-ethambutol-pyrazinamide-gatifloxacin-prothionamide (CFZ-EMBPZA-GFX-PTH) in the continuation phase for 8 months. The four most reported side effects were gastrointestinal problems, ototoxicity, dysglycemia, and liver problems. In conclusion, STR provides good effectiveness in MDR-TB treatment, in terms of treatment success rate and short therapy duration. Therapy with STR is relatively safe, with minimal side effects that can be tolerated in the majority of individuals.

Record Review

In Pakistan, the treatment of multidrug-resistant tuberculosis (MDR-TB) with a shorter treatment regimen (STR), that is, 4–6 months of amikacin, moxifloxacin (Mfx), ethionamide, clofazimine (Cfz), pyrazinamide (Z), ethambutol (E), and high-dose isoniazid, followed by 5 months of Mfx, Cfz, Z, and E, was initiated in 2018. However, there is a lack of information about its effectiveness in Pakistani healthcare settings. Therefore, this retrospective record review of MDR-TB patients treated with STR at eight treatment sites in Pakistan aimed to fill this gap. Data were analyzed using SPSS 23. Multivariate binary logistic regression (MVBLR) analysis was conducted to find factors associated with death and treatment failure, and lost to follow-up (LTFU). A P-value < 0.05 was considered statistically significant. Of 912 MDR-TB patients enrolled at the study sites, only 313 (34.3%) eligible patients were treated with STR and included in the current study. Of them, a total of 250 (79.9%) were cured, 12 (3.8%) completed treated, 31 (9.9%) died, 16 (5.1%) were LTFU, and four (1.3%) were declared as treatment failures. The overall treatment success rate was 83.7%. In MVBLR analysis, patients’ age of 41–60 (odds ratio [OR] = 4.9, P-value = 0.020) and > 60 years (OR = 3.6, P-value = 0.035), being underweight (OR = 2.7, P-value = 0.042), and previous TB treatment (OR = 0.4, P-value = 0.042) had statistically significant association with death and treatment failure, whereas patients’ age of > 60 years (OR = 5.4, P-value = 0.040) and previous TB treatment (OR = 0.2, P-value = 0.008) had statistically significant association with LTFU. The treatment success rate of STR was encouraging. However, to further improve the treatment outcomes, special attention should be paid to the patients with identified risk factors.

Background: Rifampicin-resistant (RR-TB) and multidrug-resistant tuberculosis (MDR-TB) remains a major health problem worldwide and in Indonesia also become a challenge in total eradication of tuberculosis. Dr. Kanujoso Djatiwibowo Public Hospital (RSKD) Balikpapan is one of the two referral hospitals in East Kalimantan for evaluation and initiation of MDR-TB treatment. The objective of this study is to evaluate clinical profile and treatment of RR-TB and MDR-TB patients at RSKD. Methods: A retrospective cross-sectional study was conducted using data from eTB manager database and medical record of RR-TB and MDR-TB at RSKD from January 2013 to October 2016. Results: Twenty eight RR-TB and MDR-TB patients, most of them were female (53.6%), belong to 35-44 age group (28.6%), housewife (25%), graduated from senior high school (42,9%), malnutrition (28.6%), and relapse cases (50%). Diabetes mellitus and anemia were found in 42,9% and 44.4% of the patients, respectively. The most resistant pattern is rifampicin-resistant TB (57,1%) followed by rifampicin and isoniazid resistant. The most common side effect of TB treatment was gastrointestinal complaints (44.4%). The success rate of MDRTB treatment at RSKD was 20%, followed by 20% mortality, 50% of lost to follow up, 10% of treatment failure, and there are 8 patients still ongoing therapy. Conclusion: Most of the RR-TB and MDR-TB cases were relapse cases. Counseling, education, and support for the patients undergoing MDR-TB treatment are strongly needed to increase success rate and decreasing number of lost to follow up.

Long Term Follow Up

Increasing awareness of the rising global rates of multidrug-resistant tuberculosis (MDR-TB) has led to a concerted international effort to confront this disease. Nonetheless, despite cure rates >80% in some programs, MDR-TB patients tend to have chronic disease and require prolonged therapy.1-3 Little is known about the long-term results and follow-up of patients with MDR-TB, include the recurrence rate and chronic disability in patients who have recovered from TB.4 There are many side effects and adverse reactions to drugs can occur during MDR-TB treatment. These could be physical and or psychological, as well as reversible or irreversible. Treatment of MDR-TB requires a combination regimen, consists of second and third-line anti-tuberculosis drugs which more toxic than first-line drugs. Additionally, MDR-TB treatment requires a long duration of treatment (18-24 months) and causes discomfort in the patient.5 In a cohort of 60 patients treated for MDR-TB, the most common side effects included gastritis (100%), dermatological disorders (43%), and peripheral neuropathy (16.7).6 While in a cohort of 75 patients, the incidence of depression, anxiety, and psychosis for MDR-TB treatments was 13.3%, 12.0%, and 12.0%, respectively.7 Aggressive and effective management are needed so the patient can tolerate the treatment and remain adhere the treatment.8 Long-term follow-up is required for the rehabilitation of disorders due to psychosocial sequelae.  As such, psychosocial support can be benefit pediatric MDR-TB patients.   Here, we present a case report on a two-year follow-up of a pubertal child with MDR-TB,  focusing on medical aspects and her development.

Background: Owing to the high resistance rate of tuberculosis (TB) to isoniazid, which is metabolized by N-acetyltransferase 2 (NAT2), we investigated the associations between NAT2 variants and multidrug-resistant (MDR)-TB. Materials & methods: The acetylator status based on NAT2 haplotypes of 128 patients with MDR-TB in Indonesia were compared with our published data from patients with anti-TB drug-induced liver injury (AT-DILI), TB and the general population. Results: NAT2*4 was more frequent in the MDR-TB group than in the AT-DILI group, TB controls and general controls. NAT2*4/*4 was significantly more frequent in patients with MDR-TB than in those with AT-DILI. NAT2*5B/7B, *6A/6A and *7B/*7B were detected at lower frequencies in patients with AT-DILI. Rapid acetylators were significantly more frequent in patients with MDR-TB than in those with AT-DILI. Conclusion: These results provide an initial data for optimizing TB treatment in the Indonesian population, and suggest that NAT2 genotyping may help to select appropriate treatment by predicting TB-treatment effect.

This study aimed to investigate the prevalence of multidrug-resistant tuberculosis (MDR-TB) isolates resistant to the second-line antituberculosis drugs (SLDs) and its association with resistant-related gene mutations inMycobacterium tuberculosis(M.tb) isolates from Southwest of China. There were 81 isolates resistant to at least one of the SLDs among 156 MDR-TB isolates (81/156, 51.9%). The rates of general resistance to each of the drugs were as follows: OFX (66/156, 42.3%), KAN (26/156, 16.7%), CAP (13/156, 8.3%), PTO (11/156, 7.1%), PAS (22/156, 14.1%), and AMK (20/156, 12.8%). Therefore, the most predominant pattern was resistant to OFX compared with other SLDs (P<0.001). The results of sequencing showed that 80.2% OFX-resistant MDR-TB isolates containedgyrAmutation and 88.5% KAN-resistant isolates hadrrsmutations with the most frequent mutation being A1401G. These results suggest that improper use of SLDs especially OFX is a real threat to effective MDR-TB treatment not only in China but also in the whole world. Furthermore the tuberculosis control agencies should carry out SLDs susceptibility testing and rapid screening in a broader population of TB patients immediately and the SLDs should be strictly regulated by the administration in order to maintain their efficacy to treat MDR-TB.

Background. Multidrug-resistant tuberculosis (MDR-TB) has continued to be a challenge for tuberculosis (TB) control globally. Ethiopia is one of the countries with high MDR-TB burden. Objective. The main purpose of this study was to determine the prevalence of MDR-TB and associated factors in Ethiopia. Methods. A systematic review of the literatures on prevalence of MDR-TB and associated factors was conducted in the country. Results. In our electronic search, 546 citations were depicted. Among the total 546 citations described, a total of 22 articles met eligibility criteria and were included in the review article. According to our review, the prevalence of MDR-TB ranged from 0 to 46.3%. The average mean rate of MDR-TB in Ethiopia was found to be 12.6±15.9%. The overall prevalence of MDR-TB in all TB cases was estimated to be 1.4%. From a total of 3849 patients studied, 527 had MDR-TB. Previous exposure to antituberculosis treatment was the most commonly identified risk factor of MDR-TB in Ethiopia. Conclusion. Despite relative decline in incidence of MDR-TB, the distribution and prevalence of MDR-TB continued to be a serious challenge for TB control in Ethiopia. Previous exposure to antituberculosis treatment was also the most common risk factor for MDR-TB. Therefore, strong TB and MDR-TB treatment along with tight introduction of follow-up strategies should be applied for better TB control.

BACKGROUND: Pyrazinamide (PZA) is an important anti-tuberculosis drug for multidrug-resistant tuberculosis (MDR-TB). However, PZA has recently been demoted within the hierarchy of TB drugs used for MDR-TB.METHODS: We conducted a retrospective cohort study to investigate treatment outcomes for simple MDR-TB (susceptible to both second-line injectable drugs and fluoroquinolones) according to PZA susceptibility.RESULTS: Among 216 pulmonary MDR-TB patients included in the study, 68 (31.5%) were PZA-resistant (PZA-R). The mean age was 41.8 years, and 63.4% were male. Baseline characteristics such as comorbidity, previous TB history, acid-fast bacilli (AFB) smear positivity and cavitation were similar in PZA-susceptible (PZA-S) and PZA-R patients. The number of potentially effective drugs was slightly higher among PZA-S patients than among the PZA-R (5.1 vs. 4.8, respectively; P = 0.003). PZA was more frequently used in PZA-S patients (73.0%) than in the PZA-R (14.7%), while para-aminosalicylic acid was more frequently used in PZA-R than in PZA-S patients (76.5% vs. 50.7%). The treatment success rate was similar in PZA-S (77.7%) and PZA-R (75.0%) patients. PZA resistance was not associated with treatment success in multivariate analysis.CONCLUSIONS: PZA-resistant simple MDR-TB patients had the same treatment success rate as the PZA-susceptible group even without using novel anti-TB drugs.

Living With Hiv

Tuberculosis (TB) is common among persons living with HIV. This public health concern is aggravated by infection with multidrug-resistant organisms and adverse effects of polypharmacy. There are few published cases of multidrug-resistant tuberculosis (MDR-TB) in multidrug-resistant HIV (MDR-HIV) infected patients. We report a case of a 29-year-old Filipino man with HIV on zidovudine (AZT)-containing antiretroviral therapy (ART) but was eventually shifted to tenofovir due to anaemia. He presented with left flank tenderness, which was found to be due to an MDR-TB psoas abscess, and for which second-line anti-TB treatment was started. HIV genotyping showed MDR-HIV infection susceptible only to AZT, protease inhibitors and integrase inhibitors. Subsequently, he developed neck abscess that grew Mycobacterium avium complex and was treated with ethambutol and azithromycin. ART regimen was revised to AZT plus lamivudine and lopinavir/ritonavir. Erythropoietin was administered for recurrent AZT-induced anaemia. Both abscesses resolved and no recurrence of anaemia was noted.

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.
