    Full Text Available Resumo: O presente estudo populacional, que decorreu entre 1999 e 2003, foi baseado na utilização do Spoligotyping na genotipagem de 452 isolados do complexo Mycobacterium tuberculosis de doentes com tuberculose internados no Hospital Fernando Fonseca. Spoligotypes foram identificados como shared types (ST recorrendo a uma base de dados internacional. Onze ST raros, não identificados na base de dados, acomodaram 8,4% dos isolados. Aliás, particular a Portugal poderá ser a predominância de ST identificados na base de dados mas não previamente classificados como famílias genotípicas, tais como o ST244, ST150 e ST389, representando 13,3 % do total. A identificação de isolados clínicos de M. africanum de genótipo Afri1 e de M. tuberculosis de genótipo CAS1 poderá confirmar a importação de isolados de origem africana e asiática. M. tuberculosis da família Beijing foi pela primeira vez por nós assinalado a partir de 1999. Desde então, o número de isolados provenientes do hospital passou de um para cinco, anualmente, representando actualmente 2,2%, o que a coloca em décimo lugar em prevalência. M. tuberculosis Beijing poderá corresponder a um problema emergente em Portugal devido à recente imigração proveniente da Europa Oriental e da Ásia. Outros genótipos, ST150 e ST389, mostraram um incremento, cujo significado não é claro. No entanto, as frequências relativas das famílias predominantes LAM, T1 e Haarlem mantiveram-se relativamente estáveis. O presente estudo confirma a variabilidade genética em Portugal dos isolados do complexo M. tuberculosis. Estes estudos poderão contribuir para a definição de prioridades nos programas nacionais de luta contra a tuberculose.Rev Port Pneumol 2005; XI (6: 513-531 Abstract: The present population study, from 1999 to 2003, has been based on the use of Spoligotyping in the genotyping of 452 isolates of

    Tuberculosis is a major health problem in many parts of the world. Delay in initiation of the treatment may result in prolonged infectious state, drug resistance, relapse and death. Objectives: To determine the factors responsible for not starting tuberculosis treatment among smear positive tuberculosis patients. Study type, settings and duration: This cross sectional study was done at Pakistan Medical Research Council TB Research Center, King Edward Medical University, Lahore, from fifth March 2010 to fifth December 2010. Patients and Methods: Fifty sputum smear positive patients of tuberculosis who did not register themselves in treatment register and presumably did not initiate anti tuberculosis treatment were contacted using telephone or traced by their home addresses. Once contact was established, they were inquired about the reasons for not starting tuberculosis treatment. Results: Of 50 patients 38(76%)belonged to the lower socio economic class and 12(24%) to the lower middle class. Fourteen patients (28%) were illiterate and 23(46%) had only 8 years of education. Of the 50 cases 41(82%) were taking treatment from traditional healers and 4% did not go back to the DOTS program. Physical condition of the patient, social, domestic and religious issues also played some role in default. Conclusions: Lack of health education and poverty were the main factors responsible for non compliance from treatment. Policy message: Sputum testing sites should have a paramedic who should educate the patients about the benefits of treatment and the dangers of default or partial treatment. (author)

    Early detection and appropriate treatment are the keys to tuberculosis control. In particular, providing appropriate treatment for tuberculosis in patients with HIV infection, rheumatoid arthritis (RA), chronic hepatic disease, or renal failure necessitating hemodialysis, and taking appropriate measures against adverse reactions to antituberculosis drugs are issues of critical importance. This mini-symposium, four experts explained the current status of "treatment of tuberculosis in patients with comorbidities" and proposed measures to address these problems. Dr. Aoki talked about "HIV infection complicated by tuberculosis." To the next, Dr. Yoshinaga gave a talk on "treatment of tuberculosis in RA patients receiving biological agents. Further, Dr. Sasaki lectured on "tuberculosis in patients with hepatic disease/impairment". Lastly, Dr. Takamori gave a lecture on "tuberculosis in patients with renal disease and those on hemodialysis. Tuberculosis patients often have some underlying diseases, and adverse reactions caused by antituberculosis drugs, such as hepatic and renal impairments, are matters of concern. I believe that this mini-symposium has provided useful information for physicians engaged in tuberculosis treatment and for many other healthcare professionals as well.

É o agente etiológico da tuberculose bovina, importante zoonose transmissível ao homem, principalmente através da inalação do bacilo e/ou pelo consumo de leite e derivados não-pasteurizados provenientes de vacas tuberculosas. O objetivo deste estudo foi padronizar a identificação de micobactérias do complexo M. tuberculosis presentes no leite, por metodologia molecular. Fez-se a extração de DNA diretamente do leite contaminado e realizou-se a identificação molecular pela reação em cadeia da polimerase seguida de análise de restrição do fragmento amplificado (PRA. Utilizaram-se inhagens de referência e leite cru artificialmente contaminado com M. bovis IP. Um fragmento de 441pb do gene hsp65 foi amplificado, tratado com BstEII e HaeIII e empregou-se o perfil de restrição enzimática obtido para identificar o complexo M. tuberculosis no leite. Com a PRA foi possível detectar com especificidade e sensibilidade a presença de M. bovis em até 10 UFC/mL de leite. A metodologia padronizada poderá auxiliar os métodos microbiológicos e bioquímicos tradicionalmente usados na identificação do bacilo em alimentos suspeitos de contaminação, como, por exemplo, o leite proveniente de animais suspeitos de infecção por M. bovis.

    Full Text Available Meghna Adhvaryu1, Bhasker Vakharia21Department of Biotechnology, SRK Institute of Computer Education and Applied Sciences, 2R&D, Bhuma Research in Ayurvedic and Herbal Medicine, Surat, Gujarat, IndiaAbstract: Multidrug-resistant tuberculosis has emerged worldwide, with an increasing incidence due to failure of implementation of apparently effective first-line antituberculous therapy as well as primary infection with drug-resistant strains. Failure of current therapy is attributed to a long duration of treatment leading to nonadherence and irregular therapy, lack of patient education about the disease, poverty, irregular supply by care providers, drug–drug interactions in patients coinfected with human immunodeficiency virus (HIV, inadequate regulations causing market overlap and irresponsible drug usage in the private sector, and lack of research, with no addition of new drugs in the last four decades. Present standards of care for the treatment of drug-susceptible tuberculosis, multidrug-resistant tuberculosis, tuberculosis-HIV coinfection, and latent tuberculosis infection are all unsatisfactory. Since 2000, the World Health Organization (WHO has focused on drug development for tuberculosis, as well as research in all relevant aspects to discover new regimens by 2015 and to eliminate tuberculosis as a public health concern by 2050. As a result, some 20 promising compounds from 14 groups of drugs have been discovered. Twelve candidates from eight classes are currently being evaluated in clinical trials. Ongoing research should prioritize identification of novel targets and newer application of existing drugs, discovery of multitargeted drugs from natural compounds, strengthening host factors by immunopotentiation with herbal immunomodulators, as well as protective vaccines before and after exposure, consideration of surgical measures when indicated, development of tools for rapid diagnosis, early identification of resistant strains, and

    The outcome of the chemotherapy for pulmonary, extraplumonary and disseminated tuberculosis is not well documented, especially in developing countries. This study assessed tuberculosis treatment outcome, cure-to-treatment ratio and mortality among all types of tuberculosis patients in a tertiary care setting in Saudi Arabia. All cases diagnosed and treated for active Mycobacterium tuberculosis infection between 1991 and 2000 were included retrospectively. Data collected included type of tuberculosis involvement, treatment outcome, relapse and co-morbidities. Over a ten-year period, 535 case of tuberculosis were diagnosed and treated. Isolated pulmonary tuberculosis was identified in 141 cases (26.4%), extrapulmonary tuberculosis in 339 cases (63.3%). Co-morbidities were noted in 277 (52%) patients. Immunosuppression was found in 181 (34%) cases. The cure rate was 82%. The cure-to-treatment ratio was 86% in extrapulmonary tuberculosis and 65% in disseminated tuberculosis. Overall mortality was 18%. Disseminated tuberculosis had the highest mortality (34.9%), followed by pulmonary (21.8%), the extrapulmonary tuberculosis (13.6%). Forty-seven percent of all mortalities were directly related to tuberculosis. Relapse was documented in 14 out of 349 patients (4%) who had 24 months of follow-up. Despite tertiary care support, complicated tuberculosis carries a high mortality. Earlier diagnosis and complete appropriate chemotherapy are essential for improved outcome. (author)

    The billions of people with latent tuberculosis infection serve as the seedbeds for future cases of active tuberculosis. Virtually all episodes of tuberculosis disease are preceded by a period of asymptomatic Mycobacterium tuberculosis infection; therefore, identifying infected individuals most likely to progress to disease and treating such subclinical infections to prevent future disease provides a critical opportunity to interrupt tuberculosis transmission and reduce the global burden of tuberculosis disease. Programs focusing on single strategies rather than comprehensive programs that deliver an integrated arsenal for tuberculosis control may continue to struggle. Tuberculosis preventive therapy is a poorly utilized tool that is essential for controlling the reservoirs of disease that drive the current epidemic. Comprehensive control strategies that combine preventive therapy for the most high-risk populations and communities with improved case-finding and treatment, control of transmission and health systems strengthening could ultimately lead to worldwide tuberculosis elimination. This paper outlines challenges to implementation of preventive therapy and provides pragmatic suggestions for overcoming them. It further advocates for tuberculosis preventive therapy as the core of a renewed global focus to implement a comprehensive epidemic control strategy that would reduce new tuberculosis cases to elimination targets. This strategy would be underpinned by accelerated research to further understand the biology of subclinical tuberculosis infections, develop novel diagnostics, and drug regimens specifically for subclinical tuberculosis infection, strengthen health systems, community engagement, and enhance sustainable large scale implementation of preventive therapy programs.

    Full Text Available Tuberculosis, commonly known as TB, is the second most fatal infectious disease after AIDS, caused by bacterium called Mycobacterium tuberculosis. Prolonged treatment, high pill burden, low compliance, and stiff administration schedules are factors that are responsible for emergence of MDR and XDR cases of tuberculosis. Till date, only BCG vaccine is available which is ineffective against adult pulmonary TB, which is the most common form of disease. Various unique antibodies have been developed to overcome drug resistance, reduce the treatment regimen, and elevate the compliance to treatment. Therefore, we need an effective and robust system to subdue technological drawbacks and improve the effectiveness of therapeutic drugs which still remains a major challenge for pharmaceutical technology. Nanoparticle-based ideology has shown convincing treatment and promising outcomes for chronic infectious diseases. Different types of nanocarriers have been evaluated as promising drug delivery systems for various administration routes. Controlled and sustained release of drugs is one of the advantages of nanoparticle-based antituberculosis drugs over free drug. It also reduces the dosage frequency and resolves the difficulty of low poor compliance. This paper reviews various nanotechnology-based therapies which can be used for the treatment of TB.

    BACKGROUND: Spinal tuberculosis is a common disease in orthopedic clinical practice; however, it is seldom reported after organ transplantation. The aim of this study was to investigate the diagnosis and treatment of spinal tuberculosis after organ transplantation. METHOD: Two cases were diagnosed as spinal tuberculosis after liver transplantation and were treated with socarboxazide, rifampicin, streptomycin and ethambutol for more than one year. RESULTS: After treatment with anti-tuberculosis drugs for several months, the symptoms of both patients clearly improved. Back pain disappeared, and erythrocyte sedimentation and body temperature returned to normal. CONCLUSIONS: We should highly suspect spinal tuberculosis if notalgia and night sweats are present after organ transplantation. Anti-tuberculosis therapy is an effective treatment for spinal tuberculosis after organ transplantation.

    Full Text Available Recent studies on the clinical importance of tuberculin skin tests (TST, interferon-gamma release assays (IGRAs, chest computed tomography (CT and polymerase chain reaction have provided a new approach to diagnosing ocular tuberculosis (TBC. However, both TST and IGRAs cannot distinguish between latent TBC infection and active disease. Another corroborative test in the diagnosis of intraocular TBC is the evaluation of the lungs by either chest radiography or CT. Direct evidence for the diagnosis can be obtained by examination of smears and staining for acid-fast organisms, cultures of intraocular tissue/fluid for Mycobacterium tuberculosis, and nucleic acid amplification analysis. In recent years, guidelines have been suggested for the diagnosis of intraocular TBC. The current treatment of intraocular TBC consists of use of four drugs (isoniazid, rifampicin, ethambutol and pyrazinamide taken for a long period of time (total 9-15 months.

    The purpose of this report is to present an update on the manifestations and management of ocular tuberculosis. Tuberculosis affects one-third of the world's population. The incidence of tuberculosis has increased with the increase in the HIV infected population. Following a resurgence of the disease in the US, the incidence has recently declined. Patients may develop scleritis that can be focal, nodular or diffuse with or without keratitis. Anterior granulomatous uveitis may occur. The posterior segment reveals vitritis, choroiditis, and can mimic serpiginous choroiditis and other entities. Patients who are immunosuppressed or HIV infected may develop active mycobacterial disease in the eye leading to rapid destruction of the ocular structures. The diagnosis of ocular tuberculosis is made by isolation of Mycobacterium tuberculosis on Löwestein-Jensen medium or by PCR. The diagnosis is supported by the clinical findings, imaging techniques including optical coherence tomography, fluorescein angiography, indocyanine green and ultrasonography. Tuberculin skin test helps to confirm the diagnosis. Ocular tuberculosis may occur in the absence of pulmonary disease. Patients present with a spectrum of clinical signs. The disease may mimic several clinical entities. Early diagnosis and prompt treatment of ocular tuberculosis may prevent ocular morbidity and blindness.

    Migration of population contributes to the transmission of tuberculosis (TB), particularly multidrug-resistant tuberculosis. In the countries of Western Europe, the immigrants' inflow contributes to the deterioration of the epidemiological situation. Majority of newly detected TB cases in some countries were affirmed among immigrant and foreign born population. In Poland, this problem has not been investigated up to 2005. The aim of the study was the assessment of the occurrence of tuberculosis in foreigners treated in the Mazovian Centre for Treatment of Lung Diseases and Tuberculosis in Otwock. This work had a retrospective character. The number of cases of tuberculosis in foreigners admitted between 2002 and 2007 was calculated from the data base of the Mazovian Centre for Treatment of Lung Diseases and Tuberculosis; 125 patients, whose basic demographic data, bacteriological status and the radiological changes suggested TB, were included in the study. The foreigners made up to 0.5-1.7% all tuberculosis cases treated in Mazovian Centre for Treatment of Lung Diseases and Tuberculosis. Among confirmed cases, twenty four nationalities were seen. Nationals of the Russian Federation (coming from the Republic of Chechnya) formed the biggest group (24%), followed by the Vietnamese (21%) and the Ukrainians (12%). Most of all cases were young men (77%; average age - 34 years). Children made up to 12% of all cases. Tuberculosis of lungs was predominating, and there were culture confirmed extrapulmonary locations in 13.6% of cases. Bacteriological confirmation was achieved in 53% of cases, but up to 22.7% cases were resistant to one of the antituberculosis medicines and 13.6% was multidrug-resistant. Despite the fact, that foreigners made up a small proportion among all the patient treated for tuberculosis in Mazovia, their number systematically increases. High proportion of multidrug-resistant tuberculosis reported in foreign-born cases is a concern.

    infested individual to a healthy subject mainly by means of saliva containing these microorganisms, or indirectly by inhaling the bacillus which may be present in daily used objects for months due to its high resistance. Myobacteria causing tuberculosis in the immunocompetent man are tuberculosis and bovis whereas other types may produce tuberculosis in immunocompromised individuals. The pathogenecity of this bacillus is related to its capacity of escaping from macrophage-induced destruction and provoking retarded hypersensitivity. This disease has very few oral manifestations; in general, a sore mainly located in the back of the tongue is the only observed sign. Tuberculosis threatens to become an incurable disease because of the poor administration of anti-tuberculosis programs, that is why, WHO proposes DOTS (directly observed treatment of short duration for its detection and treatment. This programs begins to achieve satisfactory results, although in the last five-year period, 88% of the patients estimated to be tuberculosis-infested was not covered by DOTS.

    Full Text Available Despite the existence of a government-run tuberculosis (TB control program, the current nationwide burden of TB continues to be a public health problem in Taiwan. Intense current and previous efforts into diagnostic, therapeutic, and preventive interventions have focused on TB in adults, but childhood TB has been relatively neglected. Children are particularly vulnerable to severe disease and death following infection, and children with latent infections become reservoirs for future transmission following disease reactivation in adulthood, thus fueling future epidemics. Additional research, understanding, and prevention of childhood TB are urgently needed. This review assesses the epidemiology, diagnosis, treatment, and relevant principles of TB vaccine development and presents efficacy data for the currently licensed vaccines.

    Tuberculosis (TB) remains a public health problem, despite recent achievements in reducing incidence and mortality rates. In Brazil, these achievements were above the worldwide average, but marked by large regional heterogeneities. In Fortaleza (5th largest city in Brazil), the tuberculosis cure rate has been declining and treatment abandonment has been increasing in the past decade, despite a reduction in incidence and an increase in directly observed therapy (DOT). These trends put efforts to eliminate tuberculosis at risk. We therefore sought to determine social and programmatic determinants of tuberculosis incidence and treatment abandonment in Fortaleza. We analyzed sociodemographic and clinical data for all new tuberculosis cases notified in the Notifiable Diseases Information System (SINAN) from Fortaleza between 2007 and 2014. We calculated incidence rates for 117 neighborhoods in Fortaleza, assessed their spatial clustering, and used spatial regression models to quantify associations between neighborhood-level covariates and incidence rates. We used hierarchical logistic regression models to evaluate how individual- and neighborhood-level covariates predicted tuberculosis treatment abandonment. There were 12,338 new cases reported during the study period. Case rates across neighborhoods were significantly positively clustered in two low-income areas close to the city center. In an adjusted model, tuberculosis rates were significantly higher in neighborhoods with lower literacy, higher sewerage access and homicide rates, and a greater proportion of self-reported black residents. Treatment was abandoned in 1901 cases (15.4%), a rate that rose by 71% between 2007 and 2014. Abandonment was significantly associated with many individual sociodemographic and clinical factors. Notably, being recommended for DOT was protective for those who completed DOT, but associated with abandonment for those who did not. Low socioeconomic status areas have higher tuberculosis

    Full Text Available Este trabalho propõe uma reflexão sobre os fundamentos epistemológicos da ciência tradicional, a partir de algumas questões que são consideradas importantes para a análise crítica do discurso psiquiátrico, entre as quais a reificação dos constructos teóricos, a existência de proposições auto-corroborativas e os processos de disjunção e redução do conhecimento. Tomando como premissas (a a construção social do conhecimento e (b o caráter fragmentário da ciência tradicional, são explicitadas as bases de um novo paradigma, "sistêmico" ou "complexo", em direção ao qual caminha a ciência contemporânea. Entre as implicações de tal paradigma para a psiquiatria estão a superação das tendências reducionistas e disjuntivas nela presentes; a compreensão da contingência de que o ser humano é, por natureza, cultural e de que nenhuma abordagem pode, isoladamente, abarcar toda a complexidade da condição humana; e um entendimento do diagnóstico psiquiátrico como um ato semiótico, o qual participa recursivamente da construção da doença. Conclui-se apontando a necessidade de diálogo interdisciplinar entre os vários discursos sobre a condição humana (neurobiológicos, psicodinâmicos, antropológicos, etc. e apresentando alguns exemplos de investigações que vão neste sentido.

    This paper explores the notion of reciprocity in the context of active pulmonary and laryngeal tuberculosis (TB) treatment and related control policies and practices. We seek to do three things: First, we sketch the background to contemporary global TB care and suggest that poverty is a key feature when considering the treatment of TB patients. We use two examples from TB care to explore the role of reciprocity: isolation and the use of novel TB drugs. Second, we explore alternative means of justifying the use of reciprocity through appeal to different moral and political theoretical traditions (i.e., virtue ethics, deontology, and consequentialism). We suggest that each theory can be used to provide reasons to take reciprocity seriously as an independent moral concept, despite any other differences. Third, we explore general meanings and uses of the concept of reciprocity, with the primary intention of demonstrating that it cannot be simply reduced to other more frequently invoked moral concepts such as beneficence or justice. We argue that reciprocity can function as a mid-level principle in public health, and generally, captures a core social obligation arising once an individual or group is burdened as a result of acting for the benefit of others (even if they derive a benefit themselves). We conclude that while more needs to be explored in relation to the theoretical justification and application of reciprocity, sufficient arguments can be made for it to be taken more seriously as a key principle within public health ethics and bioethics more generally.

    Research highlights: → Two tuberculosis models with incomplete treatment. → Intuitive epidemiological interpretations for the basic reproduction numbers. → Global dynamics of the two models. → Strategies to control the spread of tuberculosis. - Abstract: Two tuberculosis (TB) models with incomplete treatment are investigated. It is assumed that the treated individuals may enter either the latent compartment due to the remainder of Mycobacterium tuberculosis or the infectious compartment due to the treatment failure. The first model is a simple one with treatment failure reflecting the current TB treatment fact in most countries with high tuberculosis incidence. The second model refines the simple one by dividing the latent compartment into slow and fast two kinds of progresses. This improvement can be used to describe the case that the latent TB individuals have been infected with some other chronic diseases (such as HIV and diabetes) which may weaken the immunity of infected individuals and shorten the latent period of TB. Both of the two models assume mass action incidence and exponential distributions of transfers between different compartments. The basic reproduction numbers of the two models are derived and their intuitive epidemiological interpretations are given. The global dynamics of two models are all proved by using Liapunov functions. At last, some strategies to control the spread of tuberculosis are discussed.

    Tuberculosis (TB) is a major global health problem and often coincides with vitamin D deficiency. High doses of vitamin D were widely used to treat TB during the pre-antibiotic era. Vitamin D exerts its action through vitamin D receptor (VDR), and VDR gene polymorphisms are associated with susceptibility or resistance to tuberculosis as well as sputum smear and culture conversion during anti-TB treatment. In-vitro studies have revealed that 1,25-dihydroxyvitamin D3 enhances innate immunity by increased expression of various antimicrobial peptides, including cathelicidin, and induction of autophagy of the infected cells thus restricts the intracellular growth of Mycobacterium tuberculosis in macrophages. On the other hand, vitamin D has been shown to suppress the pro-inflammatory cytokine response and enhance the anti-inflammatory response. Supplementation with vitamin D in concert with treatment for TB may be beneficial with respect to minimizing the excessive tissue damage that occurs during the active stage of tuberculosis disease. Several clinical trials have evaluated vitamin D supplementation as an adjunct therapy in the treatment for tuberculosis. However, results are conflicting, owing to variations in dose regimens and outcomes. Further investigations are needed to find the optimal concentration of vitamin D for supplementation with standard anti-TB drugs to optimize treatment, which could help to effectively manage both drug-sensitive and drug-resistant tuberculosis.

    To analyze adherence to treatment of tuberculosis infection and to identify risk factors for its compliance. An observational historical cohort study. Hospital Universitari Sant Joan d'Alacant (Alicante). All patients with a tuberculin skin test (TST) done during tuberculosis contact tracing during 6 years. We included 764 tuberculosis contacts in the analysis. 59.7% of the 566 patients who completed the contact tracing, had tuberculosis infection (TI). Of the patients with TI, 45.6% had not started treatment for tuberculosis infection (TTBI). Factors associated with not starting TTBI were: age (36-65 years, RR: 5.8; 95% CI: 1.2-27.5, and > 65 years, RR: 11.3; 95% CI: 2.0-64.0), the social relationship with TB case (RR: 2.2; 95% CI 1.2-3.8), and the TST reaction (≥ 15mm; RR: 0.5; 95% CI: 0.3-0.9). The completion rate for TTBI was 80.4% among people who started therapy. The treatment regimen was associated with greater compliance to TTBT (7-9H, RR: 12.7; 95% CI: 1.5-107.3). The treatment compliance rate of Tuberculosis infection was high among people who started therapy. Almost a half of the contacts with TI did not start treatment, and associated factors were: age, social relationship, and the TST reaction. The treatment regimen was associated with greater compliance. It is important to know the factors associated with adherence to treatment of TI in each health area, and focus efforts on risk groups; thereby approaching the global control of tuberculosis.

    Default remains an important challenge for the Revised National Tuberculosis Control Programme, which has achieved improved cure rates. This study describes the pattern of time of default in patients on DOTS. Tuberculosis Unit in District Tuberculosis Centre, Yavatmal, India; Retrospective cohort study. This analysis was done among the cohort of patients of registered at the Tuberculosis Unit during the year 2004. The time of default was assessed from the tuberculosis register. The sputum smear conversion and treatment outcome were also assessed. Kaplan-Meier plots and log rank tests. Overall, the default rate amongst the 716 patients registered at the Tuberculosis Unit was 10.33%. There was a significant difference in the default rate over time between the three DOTS categories (log rank statistic= 15.49, P=0.0004). Amongst the 331 smear-positive patients, the cumulative default rates at the end of intensive phase were 4% and 16%; while by end of treatment period, the default rates were 6% and 31% in category I and category II, respectively. A majority of the smear-positive patients in category II belonged to the group 'treatment after default' (56/95), and 30% of them defaulted during re-treatment. The sputum smear conversion rate at the end of intensive phase was 84%. Amongst 36 patients without smear conversion at the end of intensive phase, 55% had treatment failure. Patients defaulting in intensive phase of treatment and without smear conversion at the end of intensive phase should be retrieved on a priority basis. Default constitutes not only a major reason for patients needing re-treatment but also a risk for repeated default.

    Full Text Available Background. The standard treatment of a new case of multidrug-resistant tuberculosis (MDR-TB according to WHO recommendations in the Republic of Moldova is performed since 2005 showing a low treatment succes. Actually the treatment success rate increased due to excluding of MDR-TB patients from the general cohort. The major rate of patients with low outcome is represented by the failed and lost to follow-up cases. The purpose of the study was to assess the impact of multidrug-resiatnce and MDR-TB on the tuberculosis treatment outcome. Materials and methods. A retrospective selective, descriptive study targeting social, demographic, economic and epidemiological peculiarities, case-management, diagnostic radiological aspects and microbiological characteristics of 187 patients with pulmonary tuberculosis registered during 2013–2015 distributed in two groups: 1st group (61 patients with established multidrug-resistant strains using conventional cultural methods and the 2nd group (126 patients with MDR-TB. Results. Multidrug-resistance was established more frequently in new cases and MDR-TB in two thirds of retreated patients. No difference was identified in gender and age distribution, social, economical, educational characteristics; case-management assessment identified a similar proportion of patients revealed by general practitioners and specialists, with low rate of screened high risk groups. All patients from the multidrug-resistant group began the standard treatment for drug-responsiveness tuberculosis before drug susceptibility testing and one third of MDR-TB group was treated from the onset with the DOTS-Plus regimen. Highest success rate was identified in the new-case subgroups of both groups and higher rate of died patients was determined in the retreated subgroups. Such a low rate of patients aggrevates the resistance. Conclusions. Early diagnosis, drug responsiveness testing and raising awareness among about treatment compliance will

    The purpose of our study was to evaluate clinical and CT findings of paradoxical response during treatment for abdominal tuberculosis. Authors reviewed the patient records of 138 patients with abdominal tuberculosis during a recent 6-year period and we selected 11 patients with a paradoxical response. The CT findings and pathologic findings of the initial lesions and new lesions were reviewed. The intervals between initiation of therapy and the detection of new lesions, improvement of new lesion and the final follow-up were evaluated. At the initial presentation, we identified tuberculous peritonitis in 8 patients, tuberculous lymphadenitis in 3 patients and ileocolic tuberculosis in two patients. New lesions were identified at 2-10 months (mean: 3.8 months) after the initiation of therapy and following improvement of the initial lesions. The new lesions were perihepatic caseous abscess (n=4), hepatic tuberculoma (n=3), hepatic caseous abscess (n=1), tuberculous lymphadenitis (n=3), ileocolic tuberculosis (n=3), and splenic tuberculoma (n=1). Improvement of new lesions was noted at 4-14 months (mean: 7.6 months). At the final follow-up of seven patients, the new lesions disappeared and four patients still had small residual lesions. New lesions that develop in a patient with initial improvement should be considered a paradoxical response that will ultimately improve with continuation of the original medication.

    Avian tuberculosis is usually caused by the bacterium Mycobacterium avium. At least 20 different types of M. avium have been identified, only three of which are known to cause disease in birds. Other types of Mycobacterium rarely cause tuberculosis in most avian species; however, parrots, macaws, and other large perching birds are susceptible to human and bovine types of tuberculosis bacilli. Avian tuberculosis generally is transmitted by direct contact with infected birds, ingestion of contaminated feed and water, or contact with a contaminated environment. Inhalation of the bacterium can cause respiratory tract infections. Wild bird studies in the Netherlands disclosed tuberculosis-infected puncture-type injuries in birds of prey that fight at the nest site (kestrels) or on the ground (buteo-type buzzards), but tuberculosisinfected injuries were not found in accipiters (falco

    It is currently very rare to find mammary involvement in cases of tuberculosis, in either primary or secondary form. Diagnosis is classically clinical and microbiological, and the basic techniques used in imaging diagnosis are mammography and ultrasound. Computed tomography may define the involvement of the thoracic wall in those cases which present as mammary masses adhering to deep levels, and is also able to evaluate accompanying pulmonary disease, if it is present. Traditionally, treatment has consisted of quadrantectomy and specific antibiotic therapy. We present a case of tuberculous mammary abscess secondary to pulmonary disease, which was treated by percutaneous drainage controlled by CT and specific antibiotic therapy. We revise the diagnosis, differential diagnosis and treatment of mammary tuberculosis. (orig.)

    A 23-year-old indigenous Guatemalan man presented in 2016 to our clinic in Sololá, Guatemala, with 10 months of recurrent neck swelling, fevers, night sweats and weight loss. Previously, he had sought care in three different medical settings, including a private physician-run clinic, a tertiary private cancer treatment centre and, finally, a rural government health post. With assistance from our institution's accompaniment staff, the patient was admitted to a public tertiary care hospital for work-up. Rifampin-susceptible tuberculosis was diagnosed, and appropriate treatment was begun. The case illustrates how low tuberculosis recognition among community health workers and health system segmentation creates obstacles to appropriate care, especially for patients with limited means. As a result, significant diagnostic and treatment delays can occur, increasing the public health burden of tuberculosis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    To analyze the CT findings of intracranial tuberculosis in children at initial stage and during follow-up after treatment. We evaluated 25 patients who were diagnosed by CSF analysis or response to anti-tuberculous medication as suffering from intracranial tuberculosis. There were 13 boys and 12 girls aged between 4 months and 14 years. Twenty-five initial and sixty-three follow-up CT scans were retrospectively analyzed. We evaluated the pattern of cisternal enhancement, the locations of infarction, and the presence of calcification and parenchymal granuloma. The changes of hydrocephalus and related complications, as well as cisternal abnormality during anti-tuberculous medication were also evaluated. The initial findings on CT scan were hydrocephalus(75%), cisternal obliteration in precontrast study(64%), thick-line or ring-shaped cisternal enhancement on postcontrast study(44%), infarctions(32%), calcifications(32%), periventricular edema(28%), and parenchymal granulomas(16%). On follow-up CT scan, hydrocephalus and cisternal enhancement had decreased to 35% and 82%, respectively, and the granulomas had changed to calcified nodules(100%). Ventriculo-peritoneal shunt or external ventricular drainage was needed in nine patient, and ventriculitis or complication of shunt procedure developed in four. Intracranial tuberculosis in children presented predominantly as meningitis involving basal cisterns and was associated with hydrocephalus. Infarction and calcification may be seen as parenchymal lesion. In spite of medical treatment, drainage was needed in about half the patients. During this treatment, the resolution of hydrocephalus, decreased cisternal enhancement, and calcification of the granlomas were seen

    The emergence of drug-resistant strains of Mycobacterium tuberculosis has become a global public health problem. Polyherbal medicines offer great hope for developing alternative drugs for the treatment of tuberculosis. To evaluate the anti-tubercular activity of polyherbal medicines used for the treatment of tuberculosis. The remedies were screened against Mycobacterium tuberculosis H37Rv using Middlebrook 7H9 media and MGIT BACTEC 960 system. They were liquid preparations from King Williams Town site A (KWTa), King Williams Town site B (KWTb), King Williams Town site C (KWTc), Hogsback first site (HBfs), Hogsback second site (HBss), Hogsback third site (HBts), East London (EL), Alice (AL) and Fort Beaufort (FB). The susceptibility testing revealed that all the remedies contain anti-tubercular activity with KWTa, KWTb, KWTc, HBfs, HBts, AL and FB exhibiting more activity at a concentration below 25 µl/ml. Furthermore, MIC values exhibited inhibitory activity with the most active remedies from KWTa, HBfs and HBts at 1.562 µg/ml. However, isoniazid showed more inhibitory activity against M. tuberculosis at 0.05 µg/ml when compare to the polyherbal remedies. This study has indicated that these remedies could be potential sources of new anti-mycobacterial agents against M. tuberculosis . However, the activity of these preparations and their active principles still require in vivo study in order to assess their future as new anti-tuberculosis agents.

    Whether the main points of treatment for bronchial obstructive syndrome (BOS) in chronic obstructive lung disease (COLD) can be adapted for patients with pulmonary tuberculosis (PT) was studied. For this purpose, 435 patients with PT with signs of BOS (forced expiratory volume at 1 second (FEV1) 70% of the normal values; 2) 229 patients with FEV1 69-50%; 3) 102 patients with FEV1 bronchial obstructive syndrome in patients with pulmonary tuberculosis was highly effective, promotes the amelioration of the degree of respiratory symptoms in patients with IPT by 2 to 8 times, in those with FCPT by more than 2-3 times, and in those with PS by 1.45-10 times. The differences in the efficiency of bronchodilator therapy depend on the baseline level of bronchial obstruction. In patients with pulmonary tuberculosis concurrent with BO, the use of current inhalation bronchodilator therapy results in a substantial increase in FEV1, which differentiates BOS in PT from COLD. The use of the proposed therapy in the multimodality treatment of patients with pulmonary tuberculosis showed no statistically significant differences in the changes in the degree of X-ray symptoms while this therapy permits acceleration of abacillation in patients with IPT by 16.8% and in those with FCPT by 14.8%. Effective bronchodilator therapy considerably enhances life quality in patients. Thus, early systematic and long-term performance of the bronchodilator therapy, based on the principles of bronchodilator therapy for COLD, in patients with PT concurrent with BOS may substantially enhance the efficiency of treatment in this category of patients.

    Preclinical treatment outcome evaluation of tuberculosis (TB) occurs primarily in mice. Current designs compare relapse rates of different regimens at selected time points, but lack information about the correlation between treatment length and treatment outcome, which is required to efficiently estimate a regimens' treatment-shortening potential. Therefore we developed a new approach. BALB/c mice were infected with a Mycobacterium tuberculosis Beijing genotype strain and were treated with rifapentine-pyrazinamide-isoniazid-ethambutol (R p ZHE), rifampicin-pyrazinamide-moxifloxacin-ethambutol (RZME) or rifampicin-pyrazinamide-moxifloxacin-isoniazid (RZMH). Treatment outcome was assessed in n = 3 mice after 9 different treatment lengths between 2-6 months. Next, we created a mathematical model that best fitted the observational data and used this for inter-regimen comparison. The observed data were best described by a sigmoidal E max model in favor over linear or conventional E max models. Estimating regimen-specific parameters showed significantly higher curative potentials for RZME and R p ZHE compared to RZMH. In conclusion, we provide a new design for treatment outcome evaluation in a mouse TB model, which (i) provides accurate tools for assessment of the relationship between treatment length and predicted cure, (ii) allows for efficient comparison between regimens and (iii) adheres to the reduction and refinement principles of laboratory animal use.

    Full Text Available Tuberculosis, known as the "White Plague" in the early 19th century, is the infectious disease, which is being researched today even in some of the most developed countries in the world. Epidemiological- epizootiological research points to the importance of pasteurizing milk as well as the transmission in aerosolized droplets in humans and animals. Mycobacterium tuberculosis (Mtb, M. bovis, M. africanum and M. microti are the mycobacteria that cause tuberculosis. Other mycobacteria cause diseases commonly known as mycobacteriosae. Pathogenesis of tuberculosis includes both host- related and mycobacterium-related factors (virulence. Mtb acts through the expression of various genes and their proteins that are detectable in the serums of the diseased only, proving these proteins are formed in the course of the disease. In humans, a diagnosis is established by the detection of antigens (and antibodies, and in animals, with the allergy tests. As far as the bovine tuberculosis is concerned, the combination of skin tuberculin and blood gamma interferon test is recommended. Sequential genome (Mtb analysis has given the basis for further research of the new vaccines.Key words: Tuberculosis, pathogenesis, immunity

    Tuberculosis is still a major health problem in industrialized countries due to specific socioeconomic factors and there is the growing need of new rapid and accurate diagnostic methods, in order to achieve higher sensitivity and specificity compared to traditional methods of microscopic sputum examination and culture. Such methods, recently introduced, are nucleic acid amplification (NAA) tests, used directly on clinical specimens and blood tests (QuantiFERON-TB, T-SPOT.TB test), measuring the IFN-gamma released by stimulated T cells. Furthermore, new drugs for the disease need to be developed, aiming to better treatment results and to prevention of Multiple Drug Resistance (MDR) cases. Critical aspects in the management of drug resistance cases should be the careful choices of drugs combination, the close follow up of the patients alongside with the patients adherence to therapy. The role of national and international tuberculosis programs is invaluable in TB control and therapy, as well as the collaboration of all the health system departments. However, most of the clinical problems that may arise are addressed by the International Standards for Tuberculosis Care-ISTC and these guidelines should be taken into consideration, at least until future research provides more promising diagnostic and therapeutic modalities for control of the disease.

    Full Text Available OBJECTIVE: The aim of this study was to evaluate the role of polymerase chain reaction (PCR in the diagnosis of spinal tuberculosis after 2 weeks of preoperative anti-tuberculosis treatment and to compare PCR to the Löwenstein - Jensen Culture (LJC and histopathological examination (HPE methods. METHODS: Twenty-five patients were included in this study. Sixteen patients were diagnosed and treated for spinal tuberculosis based on clinical and radiological evidence. Nine patients were controls. The LJC method and HPE of the specimen were performed according to hospital protocol. PCR was performed using primer encoding insertion of sequences IS6110 for mycobacterium tuberculosis complex. Clinical findings and radiological features were the gold standard for comparison. RESULTS: PCR results were 15 positive and one negative. The sensitivity and specificity of PCR was 94% and 100% respectively (with 95% confidence interval [CI] 67% to 99% and 63% to 100%, respectively. HPE results showed 13 were positive and 3 negative in the spinal tuberculosis group; for the control group, all were negative. Sensitivity and specificity value of HPE was 82 % and 100% respectively (with 95% confidence interval [CI] 54% to 95% and 63% to 100%, respectively. Use of LJC showed only one was positive and 15 were negative in the spinal tuberculosis group whole all nine in the control group were negative. Sensitivity and specificity value of LJC was 6% and 100% respectively (with 95% confidence interval [CI] 0.3% to 32% and 63% to 100%, respectively. CONCLUSION: Our findings showed that the PCR for Mycobacterium tuberculosis is reliable as a method for diagnosis of spinal tuberculosis, even after of 2 weeks of anti-TB treatment, with an overall sensitivity of 94% and specificity of 100%.

    2013-09-01

    Full Text Available OBJECTIVE: To analyze the association between clinical/epidemiological characteristics and outcomes of tuberculosis treatment in patients with concomitant tuberculosis and chronic kidney disease (CKD in Brazil. METHODS: We used the Brazilian Ministry of Health National Case Registry Database to identify patients with tuberculosis and CKD, treated between 2007 and 2011. The tuberculosis treatment outcomes were compared with epidemiological and clinical characteristics of the subjects using a hierarchical multinomial logistic regression model, in which cure was the reference outcome. RESULTS: The prevalence of CKD among patients with tuberculosis was 0.4% (95% CI: 0.37-0.42%. The sample comprised 1,077 subjects. The outcomes were cure, in 58%; treatment abandonment, in 7%; death from tuberculosis, in 13%; and death from other causes, in 22%. The characteristics that differentiated the ORs for treatment abandonment or death were age; alcoholism; AIDS; previous noncompliance with treatment; transfer to another facility; suspected tuberculosis on chest X-ray; positive results in the first smear microscopy; and indications for/use of directly observed treatment, short-course strategy. CONCLUSIONS: Our data indicate the importance of sociodemographic characteristics for the diagnosis of tuberculosis in patients with CKD and underscore the need for tuberculosis control strategies targeting patients with chronic noncommunicable diseases, such as CKD.

    Linezolid is an oxazolidinone with potent activity against M tuberculosis, and improves culture conversion and cure rates when added to treatment regimens for drug resistant tuberculosis. However, linezolid has a narrow therapeutic window, and the optimal dosing strategy that minimizes the substantial toxicity associated with linezolid's prolonged use in tuberculosis treatment has not been determined, limiting the potential impact of this anti-mycobacterial agent. This paper aims to review and summarize the current knowledge on linezolid for the treatment of drug-resistant tuberculosis. The focus is on the pharmacokinetic-pharmacodynamic determinants of linezolid's efficacy and toxicity in tuberculosis, and how this relates to defining an optimal dose. Mechanisms of linezolid toxicity and resistance, and the potential role of therapeutic drug monitoring are also covered. Expert commentary: Prospective pharmacokinetic-pharmacodynamic studies are required to define optimal therapeutic targets and to inform improved linezolid dosing strategies for drug-resistant tuberculosis.

    Full Text Available Background. Healthcare workers have an increased risk of latent tuberculosis infection (LTBI, but previous studies suggested that they might be reluctant to accept preventive tuberculosis (TB treatment. We aimed to examine doctors’ and nurses’ experience of TB screening and to explore their attitudes towards preventive TB treatment. Methods. We conducted a survey among randomly selected healthcare workers at a tertiary hospital in Sydney, Australia, using a paper-based questionnaire. Results. A total of 1,304 questionnaires were distributed and 311 (24% responses were received. The majority of hospital staff supported preventive TB treatment in health care workers with evidence of latent TB infection (LTBI in general (74%, 164/223 and for them personally (81%, 198/244 while 80 and 53 healthcare workers respectively had no opinion on the topic. Staff working in respiratory medicine were significantly less likely to support preventive TB treatment in health care workers in general or for them personally if they would have evidence of LTBI compared to other specialties (p = 0.001. Only 13% (14/106 of respondents with evidence of LTBI indicated that they had been offered preventive TB treatment. Twenty-one percent (64/306 of respondents indicated that they did not know the difference between active and latent TB. Among staff who had undergone testing for LTBI, only 33% (75/230 felt adequately informed about the meaning of their test results. Discussion. Hospital staff in general had positive attitudes towards preventive TB treatment, but actual treatment rates were low and perceived knowledge about LTBI was insufficient among a significant proportion of staff. The gap between high support for preventive TB treatment among staff and low treatment rates needs to be addressed. Better education on the concept of LTBI and the meaning of screening test results is required.

    Bronchial tuberculosis is a common complication of pulmonary tuberculosis. The present report is to investigate and analyze the indication and efficacy of surgical treatment of bronchial stricture due to severe endobronchial tuberculosis, when the drug and endoscopic treatment were no effect. Reviewed the clinical-pathological records documenting the surgical outcomes in 36 bronchial stricture due to severe endobronchial tuberculosis who underwent lobectomy or pneumonectomy enrolled in our hospital between January 2000 and February 2016. Pneumonectomy in 8 cases, lobectomy in 23 cases, sleeve resection in 5 cases. No intraoperative or early postoperative death occurred. Six patients developed complications. All 6 cases recovered well after treatment. Surgical treatment is still the recommended treatment modatity for bronchial stricture caused by endobronchial tuberculosis due to its good results. It should be performed in time when the drug and intraluninal treatment were no effect for avoiding of being progeressed.

    Under India's Revised National Tuberculosis Control Programme (RNTCP), >15% of previously-treated patients in the reported 2006 patient cohort defaulted from anti-tuberculosis treatment. To assess the timing, characteristics, and risk factors for default amongst re-treatment TB patients. For this case-control study, in 90 randomly-selected programme units treatment records were abstracted from all 2006 defaulters from the RNTCP re-treatment regimen (cases), with one consecutively-selected non-defaulter per case. Patients who interrupted anti-tuberculosis treatment for >2 months were classified as defaulters. 1,141 defaulters and 1,189 non-defaulters were included. The median duration of treatment prior to default was 81 days (25%-75% interquartile range 44-117 days) and documented retrieval efforts after treatment interruption were inadequate. Defaulters were more likely to have been male (adjusted odds ratio [aOR] 1.4, 95% confidence interval [CI] 1.2-1.7), have previously defaulted anti-tuberculosis treatment (aOR 1.3 95%CI 1.1-1.6], have previous treatment from non-RNTCP providers (AOR 1.3, 95%CI 1.0-1.6], or have public health facility-based treatment observation (aOR 1.3, 95%CI 1.1-1.6). Amongst the large number of re-treatment patients in India, default occurs early and often. Improved pre-treatment counseling and community-based treatment provision may reduce default rates. Efforts to retrieve treatment interrupters prior to default require strengthening.

    Moxifloxacin, an 8-methoxy quinolone, is an important drug in the treatment of multidrug-resistant tuberculosis and is being investigated in novel drug regimens with pretomanid, bedaquiline, and pyrazinamide, or rifapentine, for the treatment of drug-susceptible tuberculosis. Early results of these studies are promising. Although current evidence does not support the use of moxifloxacin in treatment-shortening regimens for drug-susceptible tuberculosis, it may be recommended in patients unable to tolerate standard first-line drug regimens or for isoniazid monoresistance. Evidence suggests that the standard 400-mg dose of moxifloxacin used in the treatment of tuberculosis may be suboptimal in some patients, leading to worse tuberculosis treatment outcomes and emergence of drug resistance. Furthermore, a drug interaction with the rifamycins results in up to 31% reduced plasma concentrations of moxifloxacin when these are combined for treatment of drug-susceptible tuberculosis, although the clinical relevance of this interaction is unclear. Moxifloxacin exhibits extensive interindividual pharmacokinetic variability. Higher doses of moxifloxacin may be needed to achieve drug exposures required for improved clinical outcomes. Further study is, however, needed to determine the safety of proposed higher doses and clinically validated targets for drug exposure to moxifloxacin associated with improved tuberculosis treatment outcomes. We discuss in this review the evidence for the use of moxifloxacin in drug-susceptible tuberculosis and explore the role of moxifloxacin pharmacokinetics, pharmacodynamics, and drug interactions with rifamycins, on tuberculosis treatment outcomes when used in first-line tuberculosis drug regimens. © 2017, The American College of Clinical Pharmacology.

    Full Text Available Abstract Background India has 2.0 million estimated tuberculosis (TB cases per annum with an estimated 280,000 TB-related deaths per year. Understanding when in the course of TB treatment patients die is important for determining the type of intervention to be offered and crucially when this intervention should be given. The objectives of the current study were to determine in a large cohort of TB patients in India:- i treatment outcomes including the number who died while on treatment, ii the month of death and iii characteristics associated with "early" death, occurring in the initial 8 weeks of treatment. Methods This was a retrospective study in 16 selected Designated Microscopy Centres (DMCs in Hyderabad, Krishna and Adilabad districts of Andhra Pradesh, South India. A review was performed of treatment cards and medical records of all TB patients (adults and children registered and placed on standardized anti-tuberculosis treatment from January 2005 to September 2009. Results There were 8,240 TB patients (5183 males of whom 492 (6% were known to have died during treatment. Case-fatality was higher in those previously treated (12% and lower in those with extra-pulmonary TB (2%. There was an even distribution of deaths during anti-tuberculosis treatment, with 28% of all patients dying in the first 8 weeks of treatment. Increasing age and new as compared to recurrent TB disease were significantly associated with "early death". Conclusion In this large cohort of TB patients, deaths occurred with an even frequency throughout anti-TB treatment. Reasons may relate to i the treatment of the disease itself, raising concerns about drug adherence, quality of anti-tuberculosis drugs or the presence of undetected drug resistance and ii co-morbidities, such as HIV/AIDS and diabetes mellitus, which are known to influence mortality. More research in this area from prospective and retrospective studies is needed.

    The prevalence of tuberculosis depends on various factors such as migration, homelessness, malnutrition, unemployment, bad life conditions and the aging of a society. The aim of this study was to evaluate tuberculosis in females treated at the Mazovian Treatment Centre of Tuberculosis and Lung Diseases (Mazowieckie Centrum Leczenia Chorób Płuc i Gruźlicy) in Otwock, regarding the context of demographic, social and professional status of female patients. The duration of the illness and the extent of radiographic changes were also taken into consideration. The study was carried out retrospectively. The medical documentation that was evaluated concerned 100 women, aged between 20 and 92, hospitalized at the Mazovian Treatment Centre of Tuberculosis and Lung Diseases in Otwock in the years 2005 and 2006 due to bacteriologically confirmed tuberculosis. Most women with tuberculosis lived in cities (65%), 32% of the evaluated patients lived in villages and 3% were homeless. 1/3 of females were under 40 years of age, and 1/3 were over 60 years of age. Only 29% of the women were professionally active and 25% were unemployed. 60% of women were not married. 35% of women with tuberculosis were bringing up children and 7% had abandoned their offspring. More than 1/3 of women had had tuberculosis symptoms for more than half a year before tuberculosis was diagnosed. 40% of women with tuberculosis had small radiological changes (1 to 2 lung fields); however, 26% of them had extensive changes covering 4 to 6 lung fields. The majority of women with tuberculosis in the Mazovian district are single, over 40 years old, unemployed inhabitants of cities. 30% of women in the study group had had symptoms for more than 6 months before tuberculosis was diagnosed. 40% of women with tuberculosis had very extensive radiological changes covering 4 to 6 lung fields.

    2008-10-01

    Abstract Outbreaks of extensively drug-resistant tuberculosis (XDR-TB) in developing countries and recent headlines of an American traveling with a resistant variant of tuberculosis have brought XDR-TB into the spotlight. The World Health Organization and the United States Centers for Disease Control and Prevention have identified XDR-TB as a serious public health threat and are mandating increased efforts at control of tuberculosis. Although XDR-TB is believed to be no more infectious than other variants of tuberculosis, infection with and spread of XDR-TB are concerning because of the ineffectiveness, toxicity, and cost of the available tuberculosis treatment options. Pharmacists may not be aware of the recent trends in tuberculosis resistance or of the impact that they can have on educating the public about this disease. To gain a better understanding of this disease and the potential roles for pharmacists in public health awareness of tuberculosis and in the care of patients with and at risk for this disease, we undertook an extensive search of the Internet, including Web sites of tuberculosis advocacy groups, and of MEDLINE from January 1968-March 2008. Currently, XDR-TB infection is uncommon in the United States, but if history is any indication, there is a high potential for an outbreak or epidemic. The XDR-TB variant has emerged from mismanaging multidrug-resistant tuberculosis, treating tuberculosis with too few drugs, using less effective second-line drugs, and not educating patients about the dangers of nonadherence. With only limited hopes of a novel effective drug combination regimen, use of available antimycobacterial drugs needs to be optimized. Pharmacists can be key players in the prevention and treatment of tuberculosis by promoting adherence, assessing patients for risk factors for resistant disease, providing information about disease control and prevention, and monitoring for effectiveness, adverse effects, and drug interactions.

    The failure of first-line tuberculosis treatment greatly affects multiple drug-resistant tuberculosis. In vitro study of vitamin C induces the death of M. tuberculosis bacteria and accelerates healing of tuberculosis, so the multiple drug-resistant tuberculosis can be avoided. This research aimed to identify the effect of vitamin C as a supportive treatment on the sputum conversion rate. The randomizedand double group with a parallel design by matching pair method was used to collect samples. The first group was treated with standard tuberculosis treatment, and the other was given vitamin C supplementation. Vitamin C plasma level analyzation was performed before and after two months of treatment. Sputum conversion was evaluated every week for eight weeks. The comparison of vitamin C plasma level in pre and post-treatment group was significant (p=0.03) but not in the other group. There was no significant difference in vitamin C plasma level between two groups (p=0.21). The proportion of sputum conversion rate in both group in the first week was 0% vs. 9.6% (p=0.83) and the last week of study was 83.9% vs. 100% (p=0.02). In conclusion, vitamin C supplementation has effects in improving the healing process of tuberculosis patients as indicated by higher in sputum conversion rate.

    This study aimed to estimate the cost of smear-positive drug-susceptible pulmonary tuberculosis (TB) treatment of the patients in the Azadshahr district, Golestan Province, Iran. In this retrospective study, all new smear positive pulmonary TB patients who had been registered at the district's health network between April, 2013 and December, 2015 and had successfully completed their treatment were entered into the study (45 patients). Treatment costs were estimated from the provider's perspective using an activity-based costing (ABC) method. The cost of treating a new smear-positive pulmonary TB patient was US dollar (USD) 1,409.00 (Iranian Rial, 39,438,260), which can be divided into direct and indirect costs (USD 1,226.00 [87%] and USD 183.00 [13%], respectively). The highest cost (58.1%) was related to care and management of TB patients (including 46.1% human resources costs and 12% directly-observed treatment, short course implementation) and then respectively related to hospitalization (12.1%), supportive activity centers (11.4%), transportation (6.5%), medicines (5.3%), and laboratory tests and radiography (3.2%). Using disease-specific cost studies can help the healthcare system management to have correct insight into the financial burden created by the disease. This can subsequently be used in prioritization, planning, operational budgeting, economic evaluation of programs, interventions, and ultimately in disease management.

    Objective: To explore MRI features of intracranial tuberculosis, and the dynamic evolution of intracranial tuberculosis during antituberculous treatment. Methods: From September 2009 to February 2012, seventy-two patients with intracranial tuberculosis were reviewed retrospectively. Intracranial tuberculosis lesions were divided into 3 categories: pure parenchymal tuberculosis, tuberculous meningitis and hybrid type with both parenchymal tuberculosis and tuberculous meningitis. The MRI characteristics of these lesions were analysed. According to the lesion size, pure parenchymal tuberculosis was divided into 3 subtypes: 0.3 cm or less was defined as miliary, >0.3 cm and <1.0 cm as nodule, greater than or equal to 1.0 cm as tuberculoma. Serial follow-up scans were performed in 36 patients, and dynamic MRI changes in the process of anti-tuberculosis treatment during 3 to 6 months were observed. The disappearance rate of the lesions was calculated and statistically analysed by using Chi-square test. Results: There were 883 lesions in 38 cases with parenchymal tuberculosis. Multiple lesions distributed widely, 423 lesions (47.9%) ≤0.3 cm, 330 lesions (37.4%) between 0.3-1.0 cm, and 130 lesions (14.7%) ≥ 1.0 cm. Twenty-four cases with tuberculous meningitis showed meningeal enhancement at basilar cistern. Ten cases with hybrid type presented both parenchymal tuberculosis and meningitis. Among 36 patients with serial MRI follow-up scans, 22 cases were pure parenchymal tuberculosis. The disappearance rates of military, nodules and tuberculomas were 52.2% (59/113), 33.3% (33/99) and 0, respectively, after 3 months treatment. The disappearance rates were 87.6% (99/113), 50.5% (50/99) and 18.2% (2/11), respectively, after 6 months treatment. Disappearance rate of miliary lesions was obviously higher than that of nodules at both 3 and 6 months, and the difference was statistically significant,(χ 2 =7.657, 34.786, P<0.01). Nine lesions of parenchymal tuberculosis enlarged

    Full Text Available Patterns of disease, diagnosis, treatment and prognosis of tuberculosis in 100 patients co-infected with AIDS at Casa da AIDS clinic was studied. Demographic characteristics were as follows: 76 male patients, 24 female patients, 67 caucasian, average 35.8 years-old (SD ± 8.5. Sexual transmission of HIV was reported in 68 patients. Pulmonary tuberculosis was seen in 40 patients, extrapulmonary in 11, and combined in 49 patients. In 63 patients, TCD4+ counts were below 200/mm³ when tuberculosis was diagnosed. Fifty-five patients had their diagnoses confirmed by bacteriological identification of Mycobacterium; either through direct observation and/or culture. Tuberculosis was treated with rifampin, isoniazid and pyrazinamide in 60 patients, reinforced treatment in 14 and alternative treatment in the other 13 patients. Tuberculosis therapy lasted up to 9 months in 66% of the patients. Fifty-four patients were treated with a two-drug antiretroviral regimen and the remaining 46 patients received a triple regimen, which included a protease inhibitor. Among the latter, 35 patients were co-treated with rifampin. The occurrence of hepatic liver enzyme abnormalities was statistically related to alternative antiretroviral regimens (p = 0.01 and to the co-administration of rifampin and protease inhibitor (p = 0.019. Clinical resolution of tuberculosis was obtained in 74 patients. Twelve patients died during tuberculosis treatment. Resolution of tuberculosis was statistically significant related to antituberculosis treatment adherence (p = 0.001. The risk of no response to the treatment was 1.84 times more frequent among patients treated with alternative regimens regardless of the duration of the therapy. We conclude that the characteristics of tuberculosis in HIV infected patients requires that special attention be directed to the types and duration of both antiretroviral and anti-TB therapy in order to achieve the highest level of care.

    Treatment success measured by treatment outcome monitoring (TOM) is a key programmatic output of tuberculosis (TB) control programmes. We performed a systematic literature review on national-level TOM in the 30 European Union (EU)/European Economic Areas (EEA) countries to summarise methods used to collect and report data on TOM. Online reference bibliographic databases PubMed/MEDLINE and EMBASE were searched to identify relevant indexed and non-indexed literature published between January 2000 and August 2010. The search strategy resulted in 615 potentially relevant indexed citations, of which 27 full-text national studies (79 data sets) were included for final analysis. The selected studies were performed in 10 EU/EEA countries and gave a fragmented impression of TOM in the EU/EEA. Publication year, study period, sample size, databases, definitions, variables, patient and outcome categories, and population subgroups varied widely, portraying a very heterogeneous picture. This review confirmed previous reports of considerable heterogeneity in publications of TOM results across EU/EEA countries. PubMed/MEDLINE and EMBASE indexed studies are not a suitable instrument to measure representative TOM results for the 30 EU/EEA countries. Uniform and complete reporting to the centralised European Surveillance System will produce the most timely and reliable results of TB treatment outcomes in the EU/EEA. PMID:22790913

    Abstract Objective To evaluate the impact of socioeconomic support on tuberculosis preventive therapy initiation in household contacts of tuberculosis patients and on treatment success in patients. Methods A non-blinded, household-randomized, controlled study was performed between February 2014 and June 2015 in 32 shanty towns in Peru. It included patients being treated for tuberculosis and their household contacts. Households were randomly assigned to either the standard of care provided by Peru’s national tuberculosis programme (control arm) or the same standard of care plus socioeconomic support (intervention arm). Socioeconomic support comprised conditional cash transfers up to 230 United States dollars per household, community meetings and household visits. Rates of tuberculosis preventive therapy initiation and treatment success (i.e. cure or treatment completion) were compared in intervention and control arms. Findings Overall, 282 of 312 (90%) households agreed to participate: 135 in the intervention arm and 147 in the control arm. There were 410 contacts younger than 20 years: 43% in the intervention arm initiated tuberculosis preventive therapy versus 25% in the control arm (adjusted odds ratio, aOR: 2.2; 95% confidence interval, CI: 1.1–4.1). An intention-to-treat analysis showed that treatment was successful in 64% (87/135) of patients in the intervention arm versus 53% (78/147) in the control arm (unadjusted OR: 1.6; 95% CI: 1.0–2.6). These improvements were equitable, being independent of household poverty. Conclusion A tuberculosis-specific, socioeconomic support intervention increased uptake of tuberculosis preventive therapy and tuberculosis treatment success and is being evaluated in the Community Randomized Evaluation of a Socioeconomic Intervention to Prevent TB (CRESIPT) project.

    Tuberculosis is over-represented in hard-to-reach (underserved) populations in high-income countries of low tuberculosis incidence. The mainstay of tuberculosis care is early detection of active tuberculosis (case finding), contact tracing, and treatment completion. We did a systematic review with a scoping component of relevant studies published between 1990 and 2015 to update and extend previous National Institute for Health and Care Excellence (NICE) reviews on the effectiveness of interventions for identifying and managing tuberculosis in hard-to-reach populations. The analyses showed that tuberculosis screening by (mobile) chest radiography improved screening coverage and tuberculosis identification, reduced diagnostic delay, and was cost-effective among several hard-to-reach populations. Sputum culture for pre-migration screening and active referral to a tuberculosis clinic improved identification. Furthermore, monetary incentives improved tuberculosis identification and management among drug users and homeless people. Enhanced case management, good cooperation between services, and directly observed therapy improved treatment outcome and compliance. Strong conclusions cannot be drawn because of the heterogeneity of evidence with regard to study population, methodology, and quality. Copyright © 2017 Elsevier Ltd. All rights reserved.

Results: Of 724 childhood TB cases registered during the review period, 220 (30.4% were aged 0–4 years. A high proportion of patients had pulmonary TB 420/724 (58.0%, new TB infection 713/724 (98.5%, and human immunodeficiency virus (HIV coinfection 108/724 (14.7%. About 28% (n = 201 were bacteriologically diagnosed. The proportion of TB treatment success was 601/724 (83.0%. Treatment success was significantly higher in children aged 5–14 years than those 0–4 years (85.3% vs 77.7%, P  = .01. Factors associated with unsuccessful outcomes in patients aged 0–4 years are male sex (adjusted odds ratio [aOR]: 1.2, HIV-positive status (aOR: 1.2, and clinical method of diagnosis (aOR: 5.6. Conclusions: Efforts should be made to improve TB treatment outcomes in children by ensuring early and accurate diagnosis, focused training of health workers on childhood TB-HIV care, and effective adherence counseling of caregivers.

    2016-12-01

    Gynaecomastia is a common clinical presentation that varies from benign presentations in stages of human development to hormonal pathology, mainly due to hepatic dysfunction, malignancy, and adverse pharmacologic effects. We describe the development of significant bilateral gynaecomastia after starting treatment for pulmonary tuberculosis (TB) in two males with WHO stage III Human Immunodeficiency Virus (HIV) infection on stable antiretroviral regimens. Emerging reports suggest that distinct hepatic impairment in efavirenz metabolism modulates oestrogenic activity, which may be potentiated by anti-tuberculosis therapy. Clinical application includes early recognition of efavirenz-induced gynaecomastia, especially after commencing tuberculosis treatment. To avoid decreased adherence resulting from the distressing side effect of gynecomastia, transition to an alternative ART regimen over the course of tuberculosis treatment should be considered.

    Non-adherence to tuberculosis therapy can lead to drug resistance, prolonged infectiousness, and death; therefore, understanding what causes treatment default is important. Pakistan has one of the highest burdens of tuberculosis in the world, yet there have been no qualitative studies in Pakistan that have specifically examined why default occurs. We conducted a mixed methods study at a tuberculosis clinic in Karachi to understand why patients with drug-susceptible tuberculosis default from treatment, and to identify factors associated with default. Patients attending this clinic pick up medications weekly and undergo family-supported directly observed therapy. In-depth interviews were administered to 21 patients who had defaulted. We also compared patients who defaulted with those who were cured, had completed, or had failed treatment in 2013. Qualitative analyses showed the most common reasons for default were the financial burden of treatment, and medication side effects and beliefs. The influence of finances on other causes of default was also prominent, as was concern about the effect of treatment on family members. In quantitative analysis, of 2120 patients, 301 (14.2%) defaulted. Univariate analysis found that male gender (OR: 1.34, 95% CI: 1.04-1.71), being 35-59 years of age (OR: 1.54, 95% CI: 1.14-2.08), or being 60 years of age or older (OR: 1.84, 95% CI: 1.17-2.88) were associated with default. After adjusting for gender, disease site, and patient category, being 35-59 years of age (aOR: 1.49, 95% CI: 1.10-2.03) or 60 years of age or older (aOR: 1.76, 95% CI: 1.12-2.77) were associated with default. In multivariate analysis age was the only variable associated with default. This lack of identifiable risk factors and our qualitative findings imply that default is complex and often due to extrinsic and medication-related factors. More tolerable medications, improved side effect management, and innovative cost-reduction measures are needed to reduce

    Full Text Available Historically, pharmaceutical aerosols have been employed for the treatment of obstructive airway diseases, such as asthma and chronic obstructive pulmonary disease, but in the past decades their use has been expanded to treat lung infections associated with cystic fibrosis and other respiratory diseases. Tuberculosis (TB is acquired after inhalation of aerosol droplets containing the bacilli from the cough of infected individuals. Even though TB affects other organs, the lungs are the primary site of infection, which makes the pulmonary route an ideal alternative route to administer vaccines or drug treatments. Optimization of formulations and delivery systems for anti-TB vaccines and drugs, as well as the proper selection of the animal model to evaluate those is of paramount importance if novel vaccines or drug treatments are to be successful. Pharmaceutical aerosols for patient use are generated from metered dose inhalers, nebulizers and dry powder inhalers. In addition to the advantages of providing more efficient delivery of the drug, low cost and portability, pharmaceutical dry powder aerosols are more stable than inhalable liquid dosage forms and do not require refrigeration. Methods to manufacture dry powders in respirable sizes include micronization, spray drying and other proprietary technologies. Inhalable dry powders are characterized in terms of their drug content, particle size and dispersibility to ensure deposition in the appropriate lung region and effective aerosolization from the device. These methods will be illustrated as they were applied for the manufacture and characterization of powders containing anti-tubercular agents and vaccines for pulmonary administration. The influence of formulation, selection of animal model, method of aerosol generation and administration on the efficacy demonstrated in a given study will be illustrated by the evaluation of pharmaceutical aerosols of anti-TB drugs and vaccines in guinea pigs by

    Full Text Available Deficiencies in essential trace elements are associated with impaired immunity in tuberculosis infection. However, the trace element concentrations in the serum of Korean patients with tuberculosis have not yet been investigated. This study aimed to compare the serum trace element concentrations of Korean adult patients with tuberculosis with noninfected controls and to assess the impact of serum trace element concentration on clinical outcome after antituberculosis treatment. The serum concentrations of four trace elements in 141 consecutively recruited patients with tuberculosis and 79 controls were analyzed by inductively coupled plasma-mass spectrometry. Demographic characteristics were also analyzed. Serum cobalt and copper concentrations were significantly higher in patients with tuberculosis compared with controls, while zinc and selenium concentrations were significantly lower (p < 0.01. Moreover, serum selenium and zinc concentrations were positively correlated (ρ = 0.41, p < 0.05. A high serum copper concentration was associated with a worse clinical outcome, as assessed after one month of antituberculosis therapy. Specifically, culture-positive patients had higher serum copper concentrations than culture-negative patients (p < 0.05. Patients with tuberculosis had altered serum trace element concentrations. Further research is needed to elucidate the roles of individual trace elements and to determine their clinical impact on patients with tuberculosis.

    To develop a conceptual framework of adherence to treatment among Thai people living with tuberculosis, a grounded theory approach was used. A purposive sample of 20 Thai people living with tuberculosis, aged from 23 to 85 years, was interviewed. From the participants' perspective, a core category of social belonging was highlighted, with three categories of conditions connected: personal barriers, personal resilience, and social facilitation. Personal barriers encompassed fear of stigma, concealing the illness, and lack of knowledge and motivation to complete the treatment regime. Personal resilience encompassed positive thinking and self-awareness. Social facilitation encompassed the ease of access to health services, continuity in the health service's ability to choose a directly-observed therapy observer, and social support. This study contributes a deeper understanding of the perspective of Thai people living with tuberculosis with regards to adherence to tuberculosis treatment. It might improve how local healthcare workers provide tuberculosis care, and inspire them to tailor care to people living with tuberculosis in a local community to increase personal resilience and reduce stigma. © 2017 John Wiley & Sons Australia, Ltd.

    For the first time in 40 years, a portfolio of promising new compounds for the treatment of tuberculosis is on the horizon. The introduction of new drugs in combination treatment for all forms of tuberculosis raises several issues related to patients' access to novel treatments, programmatic feasibility, cost effectiveness, and implications for monitoring and surveillance, particularly with regard to the development of drug resistance. Particular attention should be given to the identification of optimal drug combination(s) for the treatment of all forms of tuberculosis, particularly in high-risk and vulnerable groups, such as human immunodeficiency virus-coinfected persons and children, and to the rational use of new drugs. Addressing these issues adequately requires the establishment of clear guidelines to assist countries in the development of policies for the proper use of tuberculosis drugs in a way that guarantees access to best treatments for all those in need and avoids inappropriate use of new drugs. After a description of these various challenges, we present activities that will be carried out by the World Health Organization in collaboration with key stakeholders for the development of policy guidelines for optimal treatment of tuberculosis.

    Due to the implementation of the International Bank for Reconstruction and Development (IBRD) loan project "Prevention, diagnosis, treatment of tuberculosis and AIDS", a "Tuberculosis" component that is an addition to the national tuberculosis control program in 15 subjects of the Russian Federation, followed up by the Central Research Institute of Tuberculosis, Russian Academy of Medical Sciences, the 2005-2008 measures stipulated by the Project have caused substantial changes in the organization of tuberculosis control: implementation of Orders Nos. 109, 50, and 690 and supervision of their implementation; modernization of the laboratories of the general medical network and antituberbulosis service (404 kits have been delivered for clinical diagnostic laboratories and 12 for bacteriological laboratories, including BACTEC 960 that has been provided in 6 areas); 91 training seminars have been held at the federal and regional levels; 1492 medical workers have been trained in the detection, diagnosis, and treatment of patients with tuberculosis; 8 manuals and guidelines have been prepared and sent to all areas. In the period 2005-2008, the tuberculosis morbidity and mortality rates in the followed-up areas reduced by 1.2 and 18.6%, respectively. The analysis of patient cohorts in 2007 and 2005 revealed that the therapeutic efficiency evaluated from sputum smear microscopy increased by 16.3%; there were reductions in the proportion of patients having ineffective chemotherapy (from 16.1 to 11.1%), patients who died from tuberculosis (from 11.6 to 9.9%), and those who interrupted therapy ahead of time (from 11.8 to 7.8%). Implementation of the IBR project has contributed to the improvement of the national strategy and the enhancement of the efficiency of tuberculosis control.

    To investigate the association between comorbid depression and tuberculosis treatment outcomes, quality of life and disability in Ethiopia. The study involved 648 consecutive adults treated for tuberculosis at 14 primary health-care facilities. All were assessed at treatment initiation (i.e. baseline) and after 2 and 6 months. We defined probable depression as a score of 10 or above on the nine-item Patient Health Questionnaire. Data on treatment default, failure and success and on death were obtained from tuberculosis registers. Quality of life was assessed using a visual analogue scale and we calculated disability scores using the World Health Organization's Disability Assessment Scale. Using multivariate Poisson regression analysis, we estimated the association between probable depression at baseline and treatment outcomes and death. Untreated depression at baseline was independently associated with tuberculosis treatment default (adjusted risk ratio, aRR: 9.09; 95% confidence interval, CI: 6.72 to 12.30), death (aRR: 2.99; 95% CI: 1.54 to 5.78), greater disability ( β : 0.83; 95% CI: 0.67 to 0.99) and poorer quality of life ( β : -0.07; 95% CI: -0.07 to -0.06) at 6 months. Participants with probable depression had a lower mean quality-of-life score than those without (5.0 versus 6.0, respectively; P  < 0.001) and a higher median disability score (22.0 versus 14.0, respectively; P  < 0.001) at 6 months. Untreated depression in people with tuberculosis was associated with worse treatment outcomes, poorer quality of life and greater disability. Health workers should be given the support needed to provide depression care for people with tuberculosis.

    Majority of the qualified medical practitioners in the country are in the private sector and more than half of patients with tuberculosis (TB) seek treatment from them. The present study was conducted with the objective of assessing the treatment modalities in pulmonary tuberculosis by the private physicians in Meerut City, Uttar Pradesh, India. A cross-sectional study was carried out covering all the private physicians (graduates and postgraduates in Medicine and Chest Diseases) registered under the Indian Medical Association, Meerut Branch (n = 154). The physicians were interviewed by a pre-designed and pre-tested questionnaire about the treatment modalities practiced by them. Only 43.5% private physicians had attended any Revised National Tuberculosis Control Programme (RNTCP) training in the past five years. Only 33.1% of them were aware of the International Standards of Tuberculosis Care (ISTC). Fifty-three different regimens were used to treat the patients. Majority of physicians (76%) prescribed daily regimens while 24% administered both daily and intermittent treatment. None of the private physicians prescribed exclusive intermittent regimen. Eighty-seven different treatment regimens were used for the treatment of multidrug-resistant TB (MDR-TB) with none of them prescribing standard treatment under RNTCP. As majority of private practitioners do not follow RNTCP guidelines for treating TB, there is an urgent need for their continued education in this area.

    Interferon-gamma (IFN-γ) release assays (IGRAs) are used to diagnose tuberculosis (TB) but not to measure treatment response. To measure IFN-γ response to active anti-tuberculosis treatment. Patients from the Henan Provincial Chest Hospital, Henan, China, with TB symptoms and/or signs were enrolled into this prospective, observational cohort study and followed for 6 months of treatment, with blood and sputum samples collected at 0, 2, 4, 6, 8, 16 and 24 weeks. The QuantiFERON® TB-Gold assay was run on collected blood samples. Participants received a follow-up telephone call at 24 months to determine relapse status. Of the 152 TB patients enrolled, 135 were eligible for this analysis: 118 pulmonary (PTB) and 17 extra-pulmonary TB (EPTB) patients. IFN-γ levels declined significantly over time among all patients (P = 0.002), with this decline driven by PTB patients (P = 0.001), largely during the initial 8 weeks of treatment (P = 0.019). IFN-γ levels did not change among EPTB patients over time or against baseline culture or drug resistance status. After 6 months of effective anti-tuberculosis treatment, IFN-γ levels decreased significantly in PTB patients, largely over the initial 8 weeks of treatment. IFN-γ concentrations may offer some value for monitoring anti-tuberculosis treatment response among PTB patients.

    Hypothyroidism is an adverse effect of certain anti-tuberculosis drugs. This is a prospective study of the frequency and possible pathomechanisms associated with hypothyroidism due to second-line treatment of multidrug-resistant tuberculosis. Fifty human immunodeficiency virus negative patients and 20 controls were included. All participants underwent ultrasonography of the thyroid and measurement of thyroid stimulating hormone (TSH). TSH levels were checked every 3 months. If hypothyroidism was present, T3, T4 and thyroid peroxidase autoantibodies were measured, and imaging extended to scintigraphy and repeated ultrasonography. Before treatment, 7 patients (14%) and 1 control (5%) were hypothyreotic. During the first 6 months of treatment, TSH levels increased in 41 patients (82%), 39 (78%) had values above the normal range and 19 (38%) had overt hypothyroidism. As none of the patients had signs of autoimmune thyroiditis, interaction with anti-tuberculosis drugs was assumed to be the cause of hypothyroidism. Nine patients died during treatment, all of whom had developed hypothyroidism. In seven, the metabolic situation at their death was known, and they had become euthyreotic following levothyroxine substitution. TSH levels should be checked before initiating anti-tuberculosis treatment and after 3 and 6 months to start timely replacement of levothyroxine. Further studies are needed to elucidate the exact pathomechanism involved in hypothyroidism and whether hypothyroidism can be used as predictor of treatment failure.

    2017-01-01

    ABSTRACT Objective: To evaluate the prevalence of pulmonary function abnormalities and to investigate the factors affecting lung function in patients treated for pulmonary tuberculosis. Methods: A total of 214 consecutive patients (132 men and 82 women; 20-82 years of age), treated for pulmonary tuberculosis and followed at a local dispensary, underwent spirometry and plethysmography at least one year after treatment. Results: Pulmonary impairment was present in 102 (47.7%) of the 214 patients evaluated. The most common functional alteration was obstructive lung disease (seen in 34.6%). Of the 214 patients, 60 (28.0%) showed reduced pulmonary function (FEV1 below the lower limit of normal). Risk factors for reduced pulmonary function were having had culture-positive pulmonary tuberculosis in the past, being over 50 years of age, having recurrent tuberculosis, and having a lower level of education. Conclusions: Nearly half of all tuberculosis patients evolve to impaired pulmonary function. That underscores the need for pulmonary function testing after the end of treatment. PMID:28380187

    Tuberculosis (TB) is a worldwide public health problem. It is a contagious and grave disease caused by Mycobacterium tuberculosis. Current drugs such as isoniazid, pyrazinamide, and rifampicin used for the treatment of tuberculosis are potentially hepatotoxic and can lead to drug hepatitis. In order to improve the follow-up of TB patients in Cameroon, we carried out a study which aimed to evaluate the hepatotoxicity risk factors associated with anti-TB drugs. The studies were performed on 75 participants who had visited the Loum District Hospital located in the littoral region of Cameroon for their routine consultation. Participants have been selected based on pre-established criteria of inclusion and exclusion. Prior to the informed consent signature, patients were given compelling information about the objective and the result output of the study. They were questioned about antioxidant food and alcohol consumption as well as some clinical signs of hepatotoxicity such as fever, nausea, vomiting, and tiredness. The collected blood was tested for the determination of biochemical markers (transaminases and C-reactive protein) using standard spectrophotometric methods. Biochemical analysis of samples showed a significant increase (pfactors, antioxidant food consumption significantly reduced the liver injury patient percentage for the above parameters, whereas an opposite situation was observed with alcohol consumption between TB-coinfection and TB patients. Regarding the C-reactive protein results, the percentage of positive tests was very high among coinfected patients (40%) compared with the control (15%). The interactions between parameters related to alcohol consumption and intake of antioxidant foods showed a slight decrease in activity compared with interactions without food. The results showed that human immunodeficiency virus status and alcohol consumption constitutes aggravating factors for the occurrence of hepatic toxicity. In addition, the consumption of

    Full Text Available China has implemented a free-service policy for tuberculosis. However, patients still have to pay a substantial proportion of their annual income for treatment of this disease. This study describes the economic burden on patients with tuberculosis; identifies related factors by comparing two areas with different management models; and provides policy recommendation for tuberculosis control reform in China.There are three tuberculosis management models in China: the tuberculosis dispensary model, specialist model and integrated model. We selected Zhangjiagang (ZJG and Taixing (TX as the study sites, which correspond to areas implementing the integrated model and dispensary model, respectively. Patients diagnosed and treated for tuberculosis since January 2010 were recruited as study subjects. A total of 590 patients (316 patients from ZJG and 274 patients from TX were interviewed with a response rate of 81%. The economic burden attributed to tuberculosis, including direct costs and indirect costs, was estimated and compared between the two study sites. The Mann-Whitney U Test was used to compare the cost differences between the two groups. Potential factors related to the total out-of-pocket costs were analyzed based on a step-by-step multivariate linear regression model after the logarithmic transformation of the costs.The average (median, interquartile range total cost was 18793.33 (9965, 3200-24400 CNY for patients in ZJG, which was significantly higher than for patients in TX (mean: 6598.33, median: 2263, interquartile range: 983-6688 (Z = 10.42, P < 0.001. After excluding expenses covered by health insurance, the average out-of-pocket costs were 14304.4 CNY in ZJG and 5639.2 CNY in TX. Based on the multivariable linear regression analysis, factors related to the total out-of-pocket costs were study site, age, number of clinical visits, residence, diagnosis delay, hospitalization, intake of liver protective drugs and use of the second

    Patients with tuberculosis require retreatment if they fail or default from initial treatment or if they relapse following initial treatment success. Outcomes among patients receiving a standard World Health Organization Category II retreatment regimen are suboptimal, resulting in increased risk of morbidity, drug resistance, and transmission.. In this study, we evaluated the risk factors for initial treatment failure, default, or early relapse leading to the need for tuberculosis retreatment in Morocco. We also assessed retreatment outcomes and drug susceptibility testing use for retreatment patients in urban centers in Morocco, where tuberculosis incidence is stubbornly high. Patients with smear- or culture-positive pulmonary tuberculosis presenting for retreatment were identified using clinic registries in nine urban public clinics in Morocco. Demographic and outcomes data were collected from clinical charts and reference laboratories. To identify factors that had put these individuals at risk for failure, default, or early relapse in the first place, initial treatment records were also abstracted (if retreatment began within two years of initial treatment), and patient characteristics were compared with controls who successfully completed initial treatment without early relapse. 291 patients presenting for retreatment were included; 93% received a standard Category II regimen. Retreatment was successful in 74% of relapse patients, 48% of failure patients, and 41% of default patients. 25% of retreatment patients defaulted, higher than previous estimates. Retreatment failure was most common among patients who had failed initial treatment (24%), and default from retreatment was most frequent among patients with initial treatment default (57%). Drug susceptibility testing was performed in only 10% of retreatment patients. Independent risk factors for failure, default, or early relapse after initial treatment included male gender (aOR = 2.29, 95% CI 1

    Full Text Available Tuberculosis is still a significant health problem in the world, mostly in developing countries. The special significance lies in immunocompromised patients, particularly those suffering from the HIV. Urogenital tuberculosis is one of the most common forms of extrapulmonary tuberculosis, while the most commonly involved organ is the kidney. Renal tuberculosis occurs by hematogenous dissemination of mycobacterium tuberculosis from a primary tuberculosis foci in the body. Tuberculosis is characterized by the formation of pathognomonic lesions in the tissues - granulomata. These granulomata may heal spontaneously or remain stable for years. In certain circumstances in the body associated with immunosuppression, the disease may be activated. Central caseous necrosis occurs within tuberculoma, leading to formation of cavities that destroy renal parenchyma. The process may gain access to the collecting system, forming the caverns. In this way, infection can be spread distally to renal pelvis, ureter and bladder. Scaring of tissue by tuberculosis process may lead to development of strictures of the urinary tract. The clinical manifestations are presented by nonspecific symptoms and signs, so tuberculosis can often be overlooked. Sterile pyuria is characteristic for urinary tuberculosis. Dysuric complaints, flank pain or hematuria may be presented in patients. Constitutional symptoms of fever, weight loss and night sweats are presented in some severe cases. Diagnosis is made by isolation of mycobacterium tuberculosis in urine samples, by cultures carried out on standard solid media optimized for mycobacterial growth. Different imaging studies are used in diagnostics - IVU, CT and NMR are the most important. Medical therapy is the main modality of tuberculosis treatment. The first line anti-tuberculosis drugs include isoniazid, rifampicin, pyrazinamide and ethambutol. Surgical treatment is required in some cases, to remove severely damaged kidney, if

    Conclusion: Hyponatraemia, hyperkalaemia, and hypochloremia characterized some of the electrolyte imbalance among TB patients receiving treatments. The raised level of bicarbonate may be attributed to overcorrection of respiratory acidosis often found in patients with tuberculosis. Monitoring electrolytes is therefore an important component of TB management.

    Tuberculosis is an ancient disease that has become a serious public health issue in recent years, although increasing incidence has been controlled, deaths caused by Mycobacterium tuberculosis have been accentuated due to the emerging of multi-drug resistant strains and the comorbidity with diabetes mellitus and HIV. This situation is threatening the goals of world health organization (WHO) to eradicate tuberculosis in 2035. WHO has called for the creation of new drugs as an alternative for the treatment of pulmonary tuberculosis, among the plausible molecules that can be used are the antimicrobial peptides (AMPs). These peptides have demonstrated remarkable efficacy to kill mycobacteria in vitro and in vivo in experimental models, nevertheless, these peptides not only have antimicrobial activity but also have a wide variety of functions such as angiogenesis, wound healing, immunomodulation and other well-described roles into the human physiology. Therapeutic strategies for tuberculosis using AMPs must be well thought prior to their clinical use; evaluating comorbidities, family history and risk factors to other diseases, since the wide function of AMPs, they could lead to collateral undesirable effects.

    Full Text Available Tuberculosis is an infectious disease and is an important public health problem. Based on data from East Java Province Health Department reported that number of tuberculosis patient in Surabaya is the highest in East Java on year 2014. Early identification and good treatment based on the result of sputum identification are the strategy use to control tuberculosis widespread. So that why, microscopic observation to identify acid fast bacilli (AFB is the fundamental stage to determine recovery treatment. Initial sputum smear positivity is necessary to determine infectious graded. The objectives of the study were to identify of initial sputum smear positivity on treatment failure of category 1 therapy for pulmonary tuberculosis in RS Paru Surabaya year 2011-2014. This study used case control method with quantitative approach. Forty two samples were taken from secondary data. Case group is 21 samples who have treatment failure and control group is 21 successful treatment. Samples were selected by simple random sampling. The chi square correlation showed that highly positive initial smear (p = 0,045; OR = 5,4 have correlated and risk factor to treatment failure on category 1 therapy for pulmonary tuberculosis. The conclusion is patient’s high positive sputum smear initially correlated to treatment failure on category 1 therapy for pulmonary tuberculosis in RS Paru Surabaya year 2011–2014.

    Full Text Available Abstract Background Delay in tuberculosis diagnosis and treatment initiation may increase disease severity and mortality. In evaluations of tuberculosis control programmes high fatality rates during tuberculosis treatment, are used as an indicator of long delays in low HIV-prevalence settings. However, data for this presumed association between delay and fatality are lacking. We assessed the association between diagnostic delay and mortality of new smear-positive pulmonary tuberculosis patients in Vietnam. Methods Follow-up of a patient cohort included in a survey of diagnostic delay in 70 randomly selected districts. Data on diagnosis and treatment were extracted from routine registers. Patients who had died during the course of treatment were compared to those with reported cure, completed treatment or failure (survivors. Results Complete data were available for 1881/2093 (89.9% patients, of whom 82 (4.4% had died. Fatality was 4.5% for patients with ≤ 4 weeks delay, 5.0% for 5- ≤ 8 weeks delay (aOR 1.11, 95%CI 0.67–1.84 and 3.2% for > 9 weeks delay (aOR 0.69, 95%CI 0.37–1.30. Fatality tended to decline with increasing delay but this was not significant. Fatality was not associated with median diagnostic delay at district level (Spearman's rho = -0.08, P = 0.5. Conclusion Diagnostic delay is not associated with treatment mortality in Vietnam at individual nor district level, suggesting that high case fatality should not be used as an indicator of long diagnostic delay in national tuberculosis programmes.

    Full Text Available The goal of the study: to investigate treatment adherence in respiratory tuberculosis patients depending on the choice of therapy.Subjects and methods: retrospective full-design study. The case histories of adult new tuberculosis cases who were treated in TB Dispensary in 2015 were analyzed. The groups were formed based on the intake of combined drugs with fixed doses (1 tablet contained 60 mg of isoniazid, 120 mg of rifampicin, 300 mg of pyrazinamide, 225 mg of ethambutol, and 20 mg of pyridoxine – Group 1 (n = 38; or separate tablets in the doses as per drug use instructions (isoniazid, rifampicin, pyrazinamide, ethambutol – Group 2 (n = 78. The groups were compatible as per sex, age, and clinical manifestations of tuberculosis. Patients from Group 1 with the weight of 60 kg received 5 tablets and patients from Group 2 received more than 12 tablets. Patients' adherence to treatment was assessed as per regularity of intake and number of doses during the intensive phase of treatment.Results. Patients from Group 1 were regularly taking anti-tuberculosis drugs, while in Group 2 there were interruptions of treatment (7-21 days in 12 (15.4% patients. In Group, the intensive phase increased up to 90.2 ± 30.6 doses and in Group 2 this increase made 131.6 ± 65.4 doses due to late sputum conversion. In Group 1, sputum conversion was achieved during the first month of treatment in 60% of patients; and in Group 2 – in 10% of cases (p = 0.044. The frequency of transaminase elevation as a side effect was higher in Group 1, but it did not result in discontinuation of drugs. Thus, the intake of combined medication with fixed doses improved tuberculosis patients' adherence to treatment.

    To determine the clinical consequences of pulmonary tuberculosis (TB) among patients with diabetes mellitus (DM). We conducted a prospective study of patients with TB in Southern Mexico. From 1995 to 2010, patients with acid-fast bacilli or Mycobacterium tuberculosis in sputum samples underwent epidemiological, clinical and microbiological evaluation. Annual follow-ups were performed to ascertain treatment outcome, recurrence, relapse and reinfection. The prevalence of DM among 1262 patients with pulmonary TB was 29.63% (n=374). Patients with DM and pulmonary TB had more severe clinical manifestations (cavities of any size on the chest x-ray, adjusted OR (aOR) 1.80, 95% CI 1.35 to 2.41), delayed sputum conversion (aOR 1.51, 95% CI 1.09 to 2.10), a higher probability of treatment failure (aOR 2.93, 95% CI 1.18 to 7.23), recurrence (adjusted HR (aHR) 1.76, 95% CI 1.11 to 2.79) and relapse (aHR 1.83, 95% CI 1.04 to 3.23). Most of the second episodes among patients with DM were caused by bacteria with the same genotype but, in 5/26 instances (19.23%), reinfection with a different strain occurred. Given the growing epidemic of DM worldwide, it is necessary to add DM prevention and control strategies to TB control programmes and vice versa and to evaluate their effectiveness. The concurrence of both diseases potentially carries a risk of global spreading, with serious implications for TB control and the achievement of the United Nations Millennium Development Goals.

    Full Text Available Background: Fluoroquinolones are among the most commonly used antibiotics for the treatment of respiratory infections. Because fluoroquinolones show bactericidal activity against Mycobacterium tuberculosis, there is concern that their use can delay the diagnosis of tuberculosis. We conducted a systematic review and meta-analysis to assess whether empiric treatment with fluoroquinolones delays the diagnosis and treatment of tuberculosis in patients with respiratory tract infections. Objectives: The primary objective was to assess the delay in days in the diagnosis and treatment of tuberculosis, among patients who received quinolones, compared to those who received non-fluoroquinolone antibiotics. Methods: We included studies of adult patients treated with fluoroquinolones prior to a confirmed diagnosis of tuberculosis. We performed a literature search of 7 databases (including PubMed, Embase and Cochrane Library with no language restrictions. We calculated an unweighted mean of estimate of difference in delay across all studies. For the studies for which the estimate was available as a mean with standard deviation, a weighted average using a random effects meta-analysis model was estimated. Results: A total of 3983 citations were identified from the literature search; of these, 17 articles were selected for full-text review. A total of 10 studies were retained for the synthesis. These included 7 retrospective cohort studies and 3 case-control studies. Only one of these studies was from a high TB burden country, South Africa. The most commonly used fluoroquinolones were levofloxacin, gemifloxacin and moxifloxacin. The unweighted average of difference in delay between the fluoroquinolone group and non-fluoroquinolone group was 12.9 days (95% CI 6.1–19.7. When these differences were pooled using a random effects model, the weighted estimate was 10.9 days (95% CI 4.2–17.6. When stratified by acid-fast smear status, the delay was

    Full Text Available Cytokines play an essential role during active tuberculosis disease and cytokine genes have been described in association with altered cytokine levels. Therefore, the aim of this study was to verify if IFNG, IL12B, TNF, IL17A, IL10, and TGFB1 gene polymorphisms influence the immune response of Brazilian patients with pulmonary tuberculosis (PTB at different time points of antituberculosis treatment (T1, T2, and T3. Our results showed the following associations: IFNG +874 T allele and IFNG +2109 A allele with higher IFN-γ levels; IL12B +1188 C allele with higher IL-12 levels; TNF −308 A allele with higher TNF-α plasma levels in controls and mRNA levels in PTB patients at T1; IL17A A allele at rs7747909 with higher IL-17 levels; IL10 −819 T allele with higher IL-10 levels; and TGFB1 +29 CC genotype higher TGF-β plasma levels in PTB patients at T2. The present study suggests that IFNG +874T/A, IFNG +2109A/G, IL12B +1188A/C, IL10 −819C/T, and TGFB1 +21C/T are associated with differential cytokine levels in pulmonary tuberculosis patients and may play a role in the initiation and maintenance of acquired cellular immunity to tuberculosis and in the outcome of the active disease while on antituberculosis treatment.

    Pregnancy and tuberculosis treatment or prophylaxis can affect efavirenz pharmacokinetics, maternal human immunodeficiency virus type 1 (HIV-1) treatment outcomes, and mother-to-child transmission (MTCT) risk. We evaluated a prospective cohort of pregnant, HIV-infected women with and without tuberculosis in Soweto, South Africa. Pharmacokinetic sampling was performed at gestation week 37 and during the postpartum period. Efavirenz trough concentrations (Cmin) were predicted using population pharmacokinetic models. HIV-viral load was measured at delivery for mothers and at 6 weeks of age for infants. Ninety-seven women participated; 44 had tuberculosis. Median efavirenz Cmin during pregnancy was 1.35 µg/mL (interquartile range [IQR], 0.90-2.07 µg/mL; 27% had an efavirenz Cmin of pregnant women with extensive CYP2B6 genotypes had an efavirenz Cmin of HIV-viral load at delivery was more common among pregnant women with tuberculosis, in whom ART was generally initiated later. © The Author 2014.

    Medical treatment for multidrug-resistant (MDR)-tuberculosis is complex, toxic, and associated with poor outcomes. Surgical lung resection may be used as an adjunct to medical therapy, with the intent of reducing bacterial burden and improving cure rates. We conducted an individual patient data metaanalysis to evaluate the effectiveness of surgery as adjunctive therapy for MDR-tuberculosis. Individual patient data, was obtained from the authors of 26 cohort studies, identified from 3 systematic reviews of MDR-tuberculosis treatment. Data included the clinical characteristics and medical and surgical therapy of each patient. Primary analyses compared treatment success (cure and completion) to a combined outcome of failure, relapse, or death. The effects of all forms of resection surgery, pneumonectomy, and partial lung resection were evaluated. A total of 4238 patients from 18 surgical studies and 2193 patients from 8 nonsurgical studies were included. Pulmonary resection surgery was performed on 478 patients. Partial lung resection surgery was associated with improved treatment success (adjusted odds ratio [aOR], 3.0; 95% confidence interval [CI], 1.5-5.9; I(2)R, 11.8%), but pneumonectomy was not (aOR, 1.1; 95% CI, .6-2.3; I(2)R, 13.2%). Treatment success was more likely when surgery was performed after culture conversion than before conversion (aOR, 2.6; 95% CI, 0.9-7.1; I(2)R, 0.2%). Partial lung resection, but not pneumonectomy, was associated with improved treatment success among patients with MDR-tuberculosis. Although improved outcomes may reflect patient selection, partial lung resection surgery after culture conversion may improve treatment outcomes in patients who receive optimal medical therapy. © The Author 2016.

    New treatment guidelines are required to improve the tuberculosis control strategies that have been used for 30 years. Seven centers of the Barcelona Tuberculosis Research Unit (BTRU) (Unitat d'Investigació en Tuberculosi de Barcelona) are collaborating with the Division of Tuberculosis Elimination of the United States Centers for Disease Control and Prevention in a series of clinical trials on latent tuberculosis infection and tuberculosis disease. BTRU participation began in 2004 with Study 26, an evaluation of the efficacy and tolerability of rifapentine plus isoniazid administered once weekly for 3 months compared with the standard treatment for latent tuberculosis infection. The BTRU centers together enrolled 246 patients (3% of the total). General enrollment was completed in February, 2008. HIV-infected patient and child enrollment continues. Treatment with 12 doses instead of 270 doses is expected to be a clear success. However, the analysis will be completed in 2010. Study 28 (started in 2006), designed for the treatment of pulmonary tuberculosis, compared standard treatment with an experimental regimen substituting moxifloxacin for isoniazid. BTRU centers together enrolled 15 patients (3.5% of the total). The provisional results (presented at the 47th Interscience Conference on Antimicrobial Agents and Chemotherapy in Chicago, 2007) showed no difference between the sputum conversion rate of each regimen at week 8 of treatment. Study 29 is currently underway, in which rifapentine was introduced in the experimental regimen for active tuberculosis treatment. Copyright (c) 2009 SESPAS. Published by Elsevier Espana.

    2015-01-01

    Full Text Available To study the clinical efficiency of using mesodiencephalic modulation (MDM as therapy in the combination treatment of patients with pulmonary tuberculosis, the authors examined two groups: 1 the patients who received a MDM cycle in combination with chemotherapy regimens (a study group; 2 those treated using standard chemotherapy regimens (a control group. By the end of one-month therapy, the study group ceased bacterial excretion twice more often than the control group that exhibited the similar results only by the end of three-month treatment. MDM as therapy produced positive X-ray changes in 76.0% of the cases in the study group and in 44.4% in the control one. MDM used in the combination treatment of patients with tuberculosis makes it possible to reduce the length of hospital stay, the number of round-the-clock beds, and the cost of treating these patients.

    The Republic of Moldova, in Eastern Europe, has among the highest reported nationwide proportions of tuberculosis (TB) patients with multidrug-resistant tuberculosis (MDR-TB) worldwide. Default has been associated with increased mortality and amplification of drug resistance, and may contribute to the high MDR-TB rates in Moldova. To assess risk factors and timing of default from treatment for non-MDR-TB from 2007 to 2010. A retrospective analysis of routine surveillance data on all non-MDR-TB patients reported. A total of 14.7% of non-MDR-TB patients defaulted from treatment during the study period. Independent risk factors for default included sociodemographic factors, such as homelessness, living alone, less formal education and spending substantial time outside Moldova in the year prior to diagnosis; and health-related factors such as human immunodeficiency virus co-infection, greater lung pathology and increasing TB drug resistance. Anti-tuberculosis treatment is usually initiated within an institutional setting in Moldova, and the default risk was highest in the month following the phase of hospitalized treatment (among civilians) and after leaving prison (among those diagnosed while incarcerated). Targeted interventions to increase treatment adherence for patients at highest risk of default, and improving the continuity of care for patients transitioning from institutional to community care may substantially reduce risk of default.

    Bouvet, R; Le Gueut, M

    2013-06-01

    Clinicians are regularly confronted with the question of refusal of treatment from patients with tuberculosis. For several years, the French public health authorities have been studying the possibility of compelling treatment or isolation, but no plan has been implemented even though European and American experiences have shown the effectiveness of restrictive measures. Neither the statutory exceptions to the principle of consent to medical treatment nor the conditions of implementation of "required care" allow legally binding measures against patients refusing care or isolation. The legislation on serious health threats has recently been applied to the situation of a refusal of treatment in the context of tuberculosis. It allowed the patient to be ordered to observe prescribed care and the possibility of forced isolation in the event of breach of this order. The legislation on serious health threats is a response to the question of refusal of treatment from patients with tuberculosis. However the opinion of the legal authority as to its necessity and proportionality to the risk remains unknown. Copyright © 2013 SPLF. Published by Elsevier Masson SAS. All rights reserved.

    'Social capital' refers to social norms, relationships, networks and values that affect the functioning and development of society. Social capital influences health positively, but its role in the treatment outcomes of tuberculosis (TB) is not known. To study the role of social capital in determining adverse TB treatment outcomes. Of 516 patients registered under the Revised National Tuberculosis Control Programme in 2014 in Wardha Tuberculosis Unit, Wardha, India, we included 88 patients with adverse treatment outcomes as cases and 187 controls from among those without adverse outcomes. Multiple logistic regression was used to compare standardised Z-scores. A greater proportion of controls than cases belonged to higher quartiles of social capital and its domains than cases, and the mean standardised Z-score was also consistently higher among controls than cases. Respectively 47% and 15% of cases and controls were in the poorest quartile of social capital, whereas respectively 10% and 33% of cases and controls were in the richest quartile. Each unit increase in Z-score of overall social capital reduced the odds of adverse treatment outcomes by 63.1%. Appropriate interventions for building social capital for TB patients and linking them with the programme would improve programme performance.

    Tuberculosis remains the single highest contributor to the world's morbidity and mortality. Early diagnosis and prompt treatment is essential to prevent its transmission. To see the treatment response of anti tuberculosis drugs in smear negative patients and study the predictors of culture positive among smear negative tuberculosis patients. Ninety four sputum smear negative patients clinically and radiologically suggestive of tuberculosis were selected. These patients were put on anti tuberculosis drugs without waiting for their culture results. They were then followed for 8 months to see their treatment outcome. A total of 94 smear negative patients were selected and given anti tuberculosis treatment. Of these 37(39%) were culture positive and 57(61%) were culture negative. Of the 37 culture positive patients 36(97%) showed clinical or radiological improvement as compared to 46(81%) out of 57 in culture negative cases. Symptoms of cough with sputum production was significantly associated with culture positivity. On x-ray chest moderate lesion with diffuse infiltration was more common finding in 64% while extensive and cavitatory lesion was seen in 24% of all cases. Association of extensive and cavitatory lesion were seen in culture positive group. Response to anti tuberculosis drugs in sputum smear negative tubercolosis suspects was found to be effective in majority of the patients. Cough, sputum and extensive cavitatory lung lesion were the predictors of culture positive cases. There is need to train physicians on the use of anti tuberculosis therapy in smear negative suspected pulmonary tuberculosis cases, especially if they have productive cough and cavitatory lung lesions.

    Tuberculosis (TB) is a major public health problem in the world and Africa has approximately one quarter of the world's cases. One of the greatest challenges facing most TB programmes is the non-compliance to TB treatment among TB patients. This study aimed at determining the challenges of management of tuberculosis (TB) across selected Osun State health facilities. The study employed a descriptive cross-sectional design. A semi-structured questionnaire was used to collect data from 102 TB patients in the health facilities. The instrument measured socio-demographic variables, patient related factors, socio-economic variables, health care system related factors to TB disease and treatment. Data were analysed and summarized using descriptive and inferential statistics. Statistical significance was placed at p facilities (χ2 = 21.761, p facility and patient-related factors were largely responsible.

    Full Text Available Abstract. The study of prednisone safety for treatment of TB mixed with HIV-infection has been conducted. Two groups of patients were compared. The first group was consisted of 88 patients who were treated by prednisone and standard tuberculosis therapy, the second group of patients presented by 45 patients received only tuberculosis medicines. It was demonstrated that in case of prednisone using (1st group the number of CD4 limphocytes increased, intoxication symptoms disappeared fast and recovery process accelerated. Increasing of cases with unfavorable course of TB and HIV-infection in patients of first group was not registered in compare with the second group. Thus, using of prednisone therapy to treat TB mixed with HIV-infection was safe, not lead to unfavorable course of TB or HIV-infection. Such kind of treatment especially important for patients with exudative reactions.

    Full Text Available Introduction: Tuberculosis and tobacco prove to be increasingly apparent world problems. Armenia is a developing country which is facing issues related to the high rates of tobacco consumption. Moreover, it is among the list of high multi-drug resistant (MDR Tuberculosis TB burden countries. Treatment success rate in Armenia for sputum smear-positive cases never reached World Health Organization's (WHO target of 85% in last 15 years. Data from different studies completed across the world suggests that there is an association between smoking and negative treatment outcomes. Methods: This retrospective study was designed to investigate aforementioned associations between TB treatment outcomes and smoking status of TB patients. Data for the study were derived from the national data available in the electronic database of the Armenian National TB Center. Results: Based on inclusion and exclusion criteria 992 TB patients registered in 2014 were enrolled in this study. All of them are were TB patients in which 387 were smokers and 605 were non-smokers. Notably, adjusted analysis showed that individuals who smoked during TB treatment had 1.61 higher odds of having unsuccessful TB treatment outcome. Additionally, consistent with the literature, statistically significant association was identified between TB treatment outcome and other well factors such as sputum smear status (OR=2.24, p<0.01, HIV status (OR,=1.87, p<0.01 of patients, etc. Conclusions: The smoking, HIV positive status, positive sputum smear microscopy test were identified as an important factors associated with the unsuccessful TB treatment outcome in Armenia. It highlights the necessity of having specific restrictions and campaign programs to reduce smoking rates among TB patients in order to improve current TB treatment and care services throughout Armenia.

    The screening of latent tuberculosis infection (LTBI) is necessary to prevent infection in patients with chronic inflammatory disease (CID) undergoing biological treatment. We aimed to assess the efficacy of LTBI screening prior to biological treatment in Tunisia, considered as a high-incidence area of active TB disease. We conducted a retrospective study over a period of 8 years [2007-2014] including patients with chronic inflammatory rheumatism receiving biologic agents since at least 6 months. The screening of LTBI was performed according to national Tunisian guidelines. There were 35 men and 78 women. The mean age was 47.67±13.50 years. Rheumatoid arthritis (70.8%) was the most common cause of CID. The diagnosis of LTBI was established in 23 cases. Among these 23 patients, 12 patients had negative tuberculin skin test (TST) associated with positive QuantiFERON-TB Gold (QFT-G), 10 had TST more than 10mm, one patient had a TST between 5 and 10mm associated with positive QFT-G and one patient had a history of tuberculosis inadequately treated. Preventive anti-tuberculous therapy was prescribed before biological therapy initiation in cases of LTBI. During the follow-up period (3.91 years), no case of tuberculosis reactivation has been reported among patients diagnosed with LTBI. However, 2 cases of active pulmonary tuberculosis were reported in patients with initially negative TST and QFT-G. Our study showed that the Tunisian recommendations allowed detecting a LTBI in 20% of biologic therapy candidates. Preventive measures including screening of LTBI and eventually a prophylactic treatment improve the safety of biological treatments.

    New alternatives for the treatment of Tuberculosis (TB) are urgently needed and medicinal plants represent a potential option. Chamaedora tepejilote and Lantana hispida are medicinal plants from Mexico and their hexanic extracts have shown antimycobacterial activity. Bioguided investigation of these extracts showed that the active compounds were ursolic acid (UA) and oleanolic acid (OA). The activity of UA and OA against Mycobacterium tuberculosis H37Rv, four monoresistant strains, and two drug-resistant clinical isolates were determined by MABA test. The intracellular activity of UA and OA against M. tuberculosis H37Rv and a MDR clinical isolate were evaluated in a macrophage cell line. Finally, the antitubercular activity of UA and OA was tested in BALB/c mice infected with M. tuberculosis H37Rv or a MDR strain, by determining pulmonary bacilli loads, tissue damage by automated histomorphometry, and expression of IFN-γ, TNF-α, and iNOS by quantitative RT-PCR. The in vitro assay showed that the UA/OA mixture has synergistic activity. The intracellular activity of these compounds against M. tuberculosis H37Rv and a MDR clinical isolate in a macrophage cell line showed that both compounds, alone and in combination, were active against intracellular mycobacteria even at low doses. Moreover, when both compounds were used to treat BALB/c mice with TB induced by H37Rv or MDR bacilli, a significant reduction of bacterial loads and pneumonia were observed compared to the control. Interestingly, animals treated with UA and OA showed a higher expression of IFN-γ and TNF-α in their lungs, than control animals. UA and OA showed antimicrobial activity plus an immune-stimulatory effect that permitted the control of experimental pulmonary TB.

    Objective: To investigate CT features of similar Hexheimer's reaction during initial treatment of active pulmonary tuberculosis. Methods: The similar Hexheimer's reaction in 44 patients diagnosed by clinic and follow-up CT scans were retrospectively reviewed by three radiologists. Results: During initial treatment of active pulmonary tuberculosis, development of radiographic progression were observed in 57 foci, including 28 pulmonary lesions increased at the site of their original lesion or new opacities elsewhere, ipsilateral or contralateral to the original lesion or both, 10 lesions related to the pleura (pleural effusion, pleural tuberculoma), 15 lymphadenectasis, 3 thymus reactions, and 1 cardiac pericardium thickening, respectively. These reactions appeared from the 20 days to 3.5 months, then with continuation of the initial chemotherapy for 1.0-3.0 months, the radiographic response was excellent with the areas of progression and the original lesions demonstrating resolution or improvement. Conclusion: The CT appearances of similar Hexheimer's reaction during initial treatment of active tuberculosis are specific to a certainty. (authors)

    Targeted identification and treatment of people with latent tuberculosis infection (LTBI) are key components of the US tuberculosis elimination strategy. Because of recent policy changes, some LTBI treatment may shift from public health departments to the private sector. To (1) develop methodology to estimate initiation and completion of treatment with isoniazid for LTBI using claims data, and (2) estimate treatment completion rates for isoniazid regimens from commercial insurance claims. Medical and pharmacy claims data representing insurance-paid services rendered and prescriptions filled between January 2011 and March 2015 were analyzed. Four million commercially insured individuals 0 to 64 years of age. Six-month and 9-month treatment completion rates for isoniazid LTBI regimens. There was an annual isoniazid LTBI treatment initiation rate of 12.5/100 000 insured persons. Of 1074 unique courses of treatment with isoniazid for which treatment completion could be assessed, almost half (46.3%; confidence interval, 43.3-49.3) completed 6 or more months of therapy. Of those, approximately half (48.9%; confidence interval, 44.5-53.3) completed 9 months or more. Claims data can be used to identify and evaluate LTBI treatment with isoniazid occurring in the commercial sector. Completion rates were in the range of those found in public health settings. These findings suggest that the commercial sector may be a valuable adjunct to more traditional venues for tuberculosis prevention. In addition, these newly developed claims-based methods offer a means to gain important insights and open new avenues to monitor, evaluate, and coordinate tuberculosis prevention.

    SUMMARY BACKGROUND The Uganda Prisons Service (UPS) is responsible for the health of approximately 32 500 inmates in 233 prisons. In 2008 a rapid UPS assessment estimated TB prevalence at 654/100 000, three times that of the general population (183/100 000). Although treatment programs exist, little is known about treatment completion in sub-Saharan African prisons. METHODS We conducted a retrospective study of Ugandan prisoners diagnosed with TB from June 2011 to November 2012. We analyzed TB diagnosis, TB-HIV comorbidity and treatment completion from national registers and tracked prison transfers and releases. RESULTS A total of 469 prisoners were diagnosed with TB over the 1.5-year period (incidence 955/100 000 person-years). Of 466 prisoners starting treatment, 48% completed treatment, 43% defaulted, 5% died and 4% were currently on treatment. During treatment, 12% of prisoners remaining in the same prison defaulted, 53% of transfers defaulted and 81% of those released were lost to follow-up. The odds of defaulting were 8.36 times greater among prisoners who were transferred during treatment. CONCLUSIONS TB incidence and treatment default are high among Ugandan prisoners. Strategies to improve treatment completion and prevent multidrug resistance could include avoiding transfer of TB patients, improving communications between prisons to ensure treatment follow-up after transfer and facilitating transfer to community clinics for released prisoners.

    Full Text Available Introduction The primary strategy for tuberculosis control involves identifying individuals with latent tuberculosis. This study aimed to estimate the prevalence of latent tuberculosis in chronic kidney disease (CKD patients who were undergoing hemodialysis in Campo Grande, State of Mato Grosso do Sul, Brazil, to characterize the sociodemographic and clinical profiles of patients with latent tuberculosis, to verify the association between sociodemographic and clinical characteristics and the occurrence of latent tuberculosis, and to monitor patient adherence to latent tuberculosis treatment. Methods This epidemiological study involved 418 CKD patients who were undergoing hemodialysis and who underwent a tuberculin skin test. Results The prevalence of latent tuberculosis was 10.3%. The mean patient age was 53.43±14.97 years, and the patients were predominantly men (63.9%. The population was primarily Caucasian (58.6%; half (50% were married, and 49.8% had incomplete primary educations. Previous contact with tuberculosis patients was reported by 80% of the participants. Treatment adherence was 97.7%. Conclusions We conclude that the prevalence of latent tuberculosis in our study population was low. Previous contact with patients with active tuberculosis increased the occurrence of latent infection. Although treatment adherence was high in this study, it is crucial to monitor tuberculosis treatment administered to patients in health services to maintain this high rate.

    A county in Jiangsu Province, China. To estimate the costs of the diagnosis and treatment of tuberculosis (TB) from the patient's perspective and to identify determinants of the patient's financial burden. In a cross-sectional survey, we interviewed 316 patients diagnosed from January 2010 to May 2011 who had already completed their anti-tuberculosis treatment. The financial burden on TB patients included out-of-pocket costs and productivity losses. The average per capita total out-of-pocket cost was 3024.0 Chinese yuan (CNY), with a median cost of 1086 CNY (interquartile range [IQR] 480-2456). Mean out-of-pocket medical and non-medical costs were respectively 2565.7 CNY and 458.3 CNY. Productivity lost by patients and family members was 2615.2 CNY (median 500, IQR 250-2025). Factors associated with out-of-pocket costs and productivity losses included hospitalisation, adverse drug reactions, cost of drugs to 'protect' the liver, cost of second-line anti-tuberculosis drugs and diagnostic delay. Although the government of China has implemented a 'free TB service policy', the economic burden on patients is still heavy. More patient-centred interventions are essential to reduce the financial burden on patients.

    To assess the approach of international specialists, who primarily practice in tuberculosis-endemic areas, to ocular tuberculosis (TB). International experts from India, Brazil, Taiwan, and more than 10 other countries were surveyed using two clinical cases and general questions. A total of 244 experts were sent a survey about the treatment and diagnosis of ocular tuberculosis; 65 responded (27%), of whom 34 were affiliated with practices in India, while 31 primarily practice at international sites outside of India and North America. The data from this survey were compared with the results of a similar survey sent to members of the American Uveitis Society. The survey provided normative data on how physicians evaluate patients with uveitis as well as opinions about ocular TB. Responses varied widely on topics such as tests to include in the workup of undifferentiated uveitis, initial therapy, and duration of treatment. Physicians from developing countries relied more on chest CT scans and tuberculin skin testing (TST) than their counterparts in developed countries. The approach to diagnosis and management of TB is heterogeneous worldwide. However, there are substantial differences in the clinical approach to uveitis depending on the clinician's location of practice.

    Despite being a curable disease, tuberculosis (TB) remains a public health problem worldwide mainly due to lengthy treatment, as well as its toxic effects, TB/HIV co-infection and the emergence of resistant Mycobacterium tuberculosis strains. These barriers reinforcing the need for development of new antimicrobial agents, that ideally should reduce the time of treatment and be active against susceptible and resistant strains. Quinones are compounds found in natural sources and among them, the naphthoquinones show antifungal, antiparasitic, and antimycobacterial activity. Thus, we evaluated the potential antimycobacterial activity of six 1,4-naphthoquinones derivatives. We determined the minimum inhibitory concentration (MIC) of the compounds against three M. tuberculosis strains: a pan-susceptible H37Rv (ATCC 27294); one mono-resistant to isoniazid (ATCC 35822); and one mono-resistant to rifampicin (ATCC 35838); the cytotoxicity in the J774A.1 (ATCC TIB-67) macrophage lineage; performed in silico analysis about absorption, distribution, metabolism, and excretion (ADME) and docking sites. All evaluated naphthoquinones were active against the three strains with MIC between 206.6 and 12.5 μM, and the compounds with lower MIC values have also showed low cytotoxicity. Moreover, two naphthoquinones derivatives 5 and 6 probably do not exhibit cross resistance with isoniazid and rifampicin, respectively, and regarding ADME analysis, no compound violated the Lipinski's rule-of-five. Considering the set of findings in this study, we conclude that these naphthoquinones could be promising scaffolds to develop new therapeutic strategies to TB.

    One third of the earths population is infected with Mycobacterium tuberculosis (Mtb), but only 5-10% of the infected individuals develop active tuberculosis (TB) over their lifetime. The remaining 90-95% stay healthy and are called latently infected individuals. They are the biggest reservoir of the tubercle bacilli and identifying the cases of latent TB is a part of the global plan of TB control. From the clinical point of view detection of latent TB infections (LTBI) in individuals with the highest active TB risk including cases of HIV infection, autoimmune inflammatory diseases or cancer, is a priority. This review summarizes the recent findings in the pathogenesis of latent TB, its diagnosis, treatment and prevention.

    Surgical treatment for spinal tuberculosis includes focal tuberculosis debridement, segmental stability reconstruction, neural decompression and kyphotic deformity correction. For the lesions mainly involved anterior and middle column of the spine, anterior operation of debridement and fusion with internal fixation has been becoming the most frequently used surgical technique for the spinal tuberculosis. However, high risk of structural damage might relate with anterior surgery, such as damage in lungs, heart, kidney, ureter and bowel, and the deformity correction is also limited. Due to the organs are in the front of spine, there are less complications in posterior approach. Spinal pedicle screw passes through the spinal three-column structure, which provides more powerful orthopedic forces compared with the vertebral body screw, and the kyphotic deformity correction effect is better in posterior approach. In this paper, we report a 68-year-old male patient with thoracic tuberculosis who underwent surgical treatment by debridement, interbody fusion and internal fixation via posterior approach only. The patient was placed in prone position under general anesthesia. Posterior midline incision was performed, and the posterior spinal construction was exposed. Then place pedicle screw, and fix one side rod temporarily. Make the side of more bone destruction and larger abscess as lesion debridement side. Resect the unilateral facet joint, and retain contralateral structure integrity. Protect the spinal cord, nerve root. Clear sequestrum, necrotic tissue, abscess of paravertebral and intervertebral space. Specially designed titanium mesh cages or bone blocks were implanted into interbody. Fix both side rods and compress both sides to make the mesh cages and bone blocks tight. Reconstruct posterior column structure with allogeneic bone and autologous bone. Using this technique, the procedures of debridement, spinal cord decompression, deformity correction, bone grafting

  4. An evaluation of culture results during treatment for tuberculosis as surrogate endpoints for treatment failure and relapse.

    Directory of Open Access Journals (Sweden)

    Patrick P J Phillips

    Full Text Available It is widely acknowledged that new regimens are urgently needed for the treatment of tuberculosis. The primary endpoint in the Phase III trials is a composite outcome of failure at the end of treatment or relapse after stopping treatment. Such trials are usually both long and expensive. Valid surrogate endpoints measured during or at the end of treatment could dramatically reduce both the time and cost of assessing the effectiveness of new regimens. The objective of this study was to evaluate sputum culture results on solid media during treatment as surrogate endpoints for poor outcome. Data were obtained from twelve randomised controlled trials conducted by the British Medical Research Council in the 1970s and 80s in East Africa and East Asia, consisting of 6974 participants and 49 different treatment regimens. The month two culture result was shown to be a poor surrogate in East Africa but a good surrogate in Hong Kong. In contrast, the month three culture was a good surrogate in trials conducted in East Africa but not in Hong Kong. As well as differences in location, ethnicity and probable strain of Mycobacteria tuberculosis, Hong Kong trials more often evaluated regimens with rifampicin throughout and intermittent regimens, and patients in East African trials more often presented with extensive cavitation and were slower to convert to culture negative during treatment. An endpoint that is a summary measure of the longitudinal profile of culture results over time or that is able to detect the presence of M. tuberculosis later in treatment is more likely to be a better endpoint for a phase II trial than a culture result at a single time point and may prove to be an acceptable surrogate. More data are needed before any endpoint can be used as a surrogate in a confirmatory phase III trial.

    Confirmation of cure for multidrug-resistant tuberculosis (MDR-TB) patients requires laboratory tests for Mycobacterium tuberculosis growth on culture media. Outcome decisions dictate patient management, and inaccuracies place patients at an increased risk of morbidity and mortality, and may contribute to continued transmission of MDR-TB. To examine concordance between programmatic and laboratory-based MDR-TB treatment outcomes. The study population included 1658 MDR-TB patients in Peru treated between 1996 and 2002 with both program and laboratory-based outcomes. Laboratory-based outcomes were assigned according to international standards requiring at least five consecutive negative cultures in the last 12 months of treatment to confirm cure. Compared to the global culture-defined standard classification, only 1.1% of treatment successes, but 54.3% of failures, were misclassified programmatically. Overall, 10.4% of patients identified by a clinician as having a successful treatment outcome still had cultures positive for MDR-TB. Most patients with successful treatment outcomes by strict culture definitions were also classified by clinicians as having successful outcomes. However, many culture-confirmed failures were missed. In light of delays and incomplete access to culture in MDR-TB programs, efforts should be made to improve the accuracy of programmatically determined treatment outcomes.

    In the developed countries gastrointestinal tuberculosis is no longer common in clinical practice. In this setting the importance of the condition lies in the vagaries of its presentation and the fact that it is eminently treatable, usually by a combination of chemotherapy and surgery. The clinical features and complications of gastrointestinal tuberculosis are highlighted by the seven cases which we report. Diagnosis and treatment of this condition is discussed and attention is drawn to the importance of case notification. Clinicians should bear in mind the diagnosis of gastrointestinal tuberculosis when dealing with any patient with non-specific abdominal symptoms.

    To evaluate the rates, timing and determinants of default and death among adult tuberculosis patients in Nigeria. Routine surveillance data were used. A retrospective cohort study of adult tuberculosis patients treated during 2011 and 2012 in two large health facilities in Ebonyi State, Nigeria was conducted. Multivariable logistic regression analyses were used to identify independent predictors for treatment default and death. Of 1 668 treated patients, the default rate was 157 (9.4%), whilst 165 (9.9%) died. Also, 35.7% (56) of the treatment defaults and 151 (91.5%) of deaths occurred during the intensive phase of treatment. Risk of default increased with increasing age (adjusted odds ratio (aOR) 1.2; 95% confidence interval (CI) 1.1-1.9), smear-negative TB case (aOR 2.3; CI 1.5-3.6), extrapulmonary TB case (aOR 2.7; CI 1.3-5.2), and patients who received the longer treatment regimen (aOR 1.6; 1.1-2.2). Risk of death was highest in extrapulmonary TB (aOR 3.0; CI 1.4-6.1) and smear-negative TB cases (aOR 2.4; CI 1.7-3.5), rural residents (aOR 1.7; CI 1.2-2.6), HIV co-infected (aOR 2.5; CI 1.7-3.6), not receiving antiretroviral therapy (aOR 1.6; CI 1.1-2.9), and not receiving cotrimoxazole prophylaxis (aOR 1.7; CI 1.2-2.6). Targeted interventions to improve treatment adherence for patients with the highest risk of default or death are urgently needed. This needs to be urgently addressed by the National Tuberculosis Programme. Copyright © 2014 Hainan Medical College. Published by Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Treatment delay is an important indicator of access to tuberculosis diagnosis and treatment. Analyses of patient delay (i.e. time interval between onset of symptoms and first consultation of a health care provider and health care delay (i.e. time interval between first consultation and start of treatment can inform policies to improve access. This study assesses the patient, health care provider and total delay in diagnosis and treatment of new smear-positive pulmonary tuberculosis patients, and the risk factors for long delay, in Vietnam. Methods A cross-sectional survey of new patients treated by the National Tuberculosis Control Programme was conducted in 70 randomly selected districts in Vietnam. All consecutively registered patients in one quarter of 2002 were interviewed using a pre-coded structured questionnaire. Results Median (range delay was 4 weeks (1–48 for total, 3 (1–48 weeks for patient and 1 (0–25 week for health care delay. Patients with long total delay (≥ 12 weeks, 15% accounted for 49% of the cumulative number of delay-weeks. Independent risk factors (p 5 km distance from a health facility or in the northern area. For long health care delay (≥ 6 weeks this was urban setting, residence in the central area and initial visit to a communal health post, TB hospital or the private sector. Conclusion Analyses of patient and treatment delays can indicate target groups and areas for health education and strengthening of the referral system, in particular between the private sector and the NTP.

    There are currently 18 drug classes for the treatment of tuberculosis, including those in the development pipeline. An in silico simulation enabled combing the innumerably large search space to derive multidrug combinations. Through the use of ordinary differential equations (ODE), we constructed an in silico kinetic platform in which the major metabolic pathways in Mycobacterium tuberculosis and the mechanisms of the antituberculosis drugs were integrated into a virtual proteome. The optimized model was used to evaluate 816 triplets from the set of 18 drugs. The experimentally derived cumulative fractional inhibitory concentration (∑FIC) value was within twofold of the model prediction. Bacterial enumeration revealed that a significant number of combinations that were synergistic for growth inhibition were also synergistic for bactericidal effect. The in silico-based screen provided new starting points for testing in a mouse model of tuberculosis, in which two novel triplets and five novel quartets were significantly superior to the reference drug triplet of isoniazid, rifampin, and ethambutol (HRE) or the quartet of HRE plus pyrazinamide (HREZ).

    Buchman, Tavora; Cabello, Celina

    Tuberculosis (TB) treatment completion is in part determined by patient's adherence to long-term drug regimens. To best ensure compliance, directly observed therapy (DOT) is considered the standard of practice. Nassau County Department of Health TB Control is responsible for providing DOT to patients with TB. Tuberculosis Control sought to use and evaluate Skype Observed Therapy (SOT) as an alternative to DOT for eligible patients. The evaluation included analysis of patient's acceptance and adherence to drug regimen using SOT. Tuberculosis Control assessed staff efficiency and cost savings for this program. Percentages of SOT of patients and successful SOT visits, mileage, and travel time savings. Twenty percent of the caseload used SOT and 100% of patients who were eligible opted in. Average SOT success was 79%. Total mileage savings and time saved were $9,929.07 and 614 hours. Because SOT saves cost and time and is a suitable alternative to DOT for patients, it should be considered as part of new policies and practices in TB control programs.

    Granulocytes are activated during tuberculosis (TB) infection and act as immune effector cells and granulocyte responses are implicated in TB pathogenesis. Plasma levels of neutrophil and eosinophil granular proteins provide an indirect measure of degranulation. In this study, we wanted to examine the levels of neutrophil and eosinophil granular proteins in individuals with pulmonary tuberculosis (PTB) and to compare them with the levels in latent TB (LTB) individuals. Hence, we measured the plasma levels of myeloperoxidase (MPO), neutrophil elastase, and proteinase-3; major basic protein (MBP), eosinophil derived neurotoxin (EDN), eosinophil cationic protein (ECP) and eosinophil peroxidase (EPX) in these individuals. Finally, we also measured the levels of all of these parameters in PTB individuals following anti-tuberculosis (ATT) treatment. Our data reveal that PTB individuals are characterized by significantly higher plasma levels of MPO, elastase, human proteinase 3 as well as MBP and EDN in comparison to LTB individuals. Our data also reveal that ATT resulted in reversal of all of these changes, indicating an association with TB disease. Finally, our data show that the systemic levels of MPO and proteinase-3 can significantly discriminate PTB from LTB individuals. Thus, our data suggest that neutrophil and eosinophil granular proteins could play a potential role in the innate immune response and therefore, the pathogenesis of pulmonary TB.

    Full Text Available Introduction: Delay in the diagnosis of tuberculosis increases the risk of death and enhances the transmission of disease in the community. This study aims to determine the patient and health service delay and factors affecting it in tuberculosis diagnosis. Materials & Methods: A cross-sectional survey that included all the public health centers was conducted in Markazi province from March 2009 till June 2011. Patients were interviewed after diagnosis by using a structured questionnaire. Results: One hundred and sixty-six patients aged between 9 and 87 (median; 66 years were included in the study. They comprised 87 (52.4% females and 79 (47.6% males. The median and mean of patient delay was 35 and 62 days, respectively; the median and mean of health system diagnosis delay was 34 and 53 days, respectively; the median and mean of health system treatment delay was 5 and 6 days, respectively; The median and mean of total delays were 86 and 121 days, respectively for all patients. The main determinants of delay were non education, poor economic, private sector, female gender and age≥55. Conclusion: The results of this review suggest that there is a need for revising case-finding strategies and reduction of infectious cases for better control of tuberculosis.

    Full Text Available There is limited information of level of drug resistance to first-line and second line anti-tuberculosis agents in treatment naïve pulmonary tuberculosis (PTB patients from the Indian region. Therefore, the present prospective study was conducted to determine the antimicrobial susceptibility to first-line and second line anti-TB drug resistance in such patients. Sputum samples from consecutive treatment naïve PTB cases registered in Lala Ram Sarup (LRS district, under RNTCP containing 12 Directly Observed Treatment Centre’s (DOTS, were enrolled using cluster sampling technology. A total of 453 samples were received from July 2011 to June 2012. All samples were cultured on solid medium followed by drug susceptibility to first and second line anti-tubercular drugs as per RNTCP guidelines. Primary multi-drug resistance (MDR was found to be 18/453; (4.0%. Extensively drug resistance (XDR was found in one strain (0.2%, which was found to be resistant to other antibiotics. Data of drug resistant tuberculosis among treatment naïve TB patients are lacking in India. The presence of XDR-TB and high MDR-TB in small population studied, calls for conducting systematic multi-centric surveillance across the country.

    To determine the predictors of noncompliance with the pulmonary tuberculosis treatment regimen recommended by the Brazilian National Ministry of Health, in previously treatment-naïve patients with active tuberculosis treated in the city of Porto Alegre, Brazil. This was a case-control study involving six referral primary health care clinics for tuberculosis in Porto Alegre. We reviewed the medical charts of all previously treatment-naïve patients with active pulmonary tuberculosis who were noncompliant with the treatment between 2004 and 2006. Those were paired with other patients having similar characteristics and having been cured. We conducted univariate and multivariate analyses. Of the 2,098 patients included, 218 (10.4%) became noncompliant with the treatment. In the multivariate analysis, the factors most strongly associated with treatment noncompliance were being an alcoholic (with or without concomitant use of illicit drugs), being HIV-infected, not residing with family members, and having a low level of education. In the univariate analysis, treatment noncompliance was also significantly associated with being younger and with being non-White. Gender was not significantly associated with treatment noncompliance; nor was the occurrence of adverse effects of the drugs included in the regimen. In the population studied, being an alcoholic, being HIV-infected, and not residing with family members were the major predictors of noncompliance with treatment for pulmonary tuberculosis among previously treatment-naïve patients.

    Full Text Available Tuberculosis (TB destroys lung tissues and this immunopathology is mediated in part by Matrix Metalloproteinases (MMPs. There are no data on the relationship between local tissue MMPs concentrations, anti-tuberculosis therapy and sputum conversion.Induced sputum was collected from 68 TB patients and 69 controls in a cross-sectional study. MMPs concentrations were measured by Luminex array, TIMP concentrations by ELISA and were correlated with a disease severity score (TBscore. 46 TB patients were then studied longitudinally at the 2nd, 8th week and end of treatment.Sputum MMP-1,-2,-3,-8,-9 and TIMP-1 and -2 concentrations are increased in TB. Elevated MMP-1 and -3 concentrations are independently associated with higher TB severity scores (p<0.05. MMP-1, -3 and -8 concentrations decreased rapidly during treatment (p<0.05 whilst there was a transient increase in TIMP-1/2 concentrations at week 2. MMP-2, -8 and -9 and TIMP-2 concentrations were higher at TB diagnosis in patients who remain sputum culture positive at 2 weeks and MMP-3, -8 and TIMP-1 concentrations were higher in these patients at 2nd week of TB treatment.MMPs are elevated in TB patients and associate with disease severity. This matrix-degrading phenotype resolves rapidly with treatment. The MMP profile at presentation correlates with a delayed treatment response.

    In 2012, the World Health Organization estimated that there were 120,000 new cases and 9500 deaths due to tuberculosis (TB) in Kenya. Almost a quarter of the cases were not detected, and the treatment of 4% of notified cases ended in default. To identify the determinants of anti-tuberculosis treatment default. Data from 2012 and 2013 were retrieved from a national case-based electronic data recording system. A comparison was made between new pulmonary TB patients for whom treatment was interrupted vs. those who successfully completed treatment. A total of 106,824 cases were assessed. Human immunodeficiency virus infection was the single most influential risk factor for default (aOR 2.7). More than 94% of patients received family-based directly observed treatment (DOT) and were more likely to default than patients who received DOT from health care workers (aOR 2.0). Caloric nutritional support was associated with lower default rates (aOR 0.89). Males were more likely to default than females (aOR 1.6). Patients cared for in the private sector were less likely to default than those in the public sector (aOR 0.86). Understanding the factors contributing to default can guide future program improvements and serve as a proxy to understanding the factors that constrain access to care among undetected cases.

    Pathanamthitta district is implementing Revised National Tuberculosis Control Program as a pilot district since 1993. The district programme was reporting approximately 5% of their diagnosed smear positive patients as never put on treatment (Initial lost to follow up - ILFU) and 5% of the new smear positive [NSP] Pulmonary TB patients as lost to follow up [LFU] during treatment. Attempts based on reengineering of DOTS were not largely successful in bringing down these proportions. A treatment support group [TSG] is a non-statutory body of socially responsible citizens and volunteers to provide social support to each needy TB patient safeguarding his dignity and confidentiality by ensuring access to information, free and quality services and social welfare programs, empowering the patient for making decision to complete treatment successfully. It is a complete fulfilment of social inclusion standards enumerated by Standards for TB Care in India. Pathanamthitta district started implementing this strategy since 2013. After intervention, proportion of LFU among NSPTB cases dropped markedly and no LFU were reported among the latest treatment cohorts. Proportion of ILFU keeps similar trend and none were reported among the latest diagnostic cohorts. Social support for TB care is feasible under routine program conditions. Addition of standards for social inclusion in STCI is meaningful. Its meaning is translated well by a society empowered with literacy and political sense.

    SUMMARY SETTING Patients who initiated treatment for multi-drug-resistant tuberculosis (MDR-TB) at 15 Programmatic Management of Drug-resistant Tuberculosis (PMDT) health facilities in the Philippines between July and December 2012. OBJECTIVES To describe patients’ views of current interventions, and suggest changes likely to reduce MDR-TB loss to follow-up. METHODS In-depth interviews were conducted between April and July 2014 with MDR-TB patients who were undergoing treatment, had finished treatment at the time of the interview (controls), or had been lost to follow-up (LTFU). Responses were thematically analyzed. RESULTS Interviews were conducted with 182 patients who were undergoing or had completed treatment and 91 LTFU patients. Views and suggestions could be thematically categorized as approaches to facilitate adherence or address barriers to adherence. The top themes were the need for transportation assistance or improvements to the current transportation assistance program, food assistance, and difficulties patients encountered related to their medications. These themes were addressed by respectively 63%, 60%, and 32% of the participants. CONCLUSIONS A more patient-centered approach is needed to improve MDR-TB treatment adherence. Programs should strive to provide assistance that considers patient preferences, is adequate to cover actual costs or needs, and is delivered in a timely, uninterrupted manner. PMID:28157461

    To explore an method and the effectiveness of surgical treatment of thoracic and lumbar tuberculosis complicated with severe kyphotic deformity (Cobb angle ≥ 55°) and paraplegia. Between January 2009 and January 2013, 13 cases of thoracic and lumbar tuberculosis complicated with severe kyphotic deformity and paraplegia were treated by one-stage posterior vertebral column resection (PVCR), debridement, bone grafting, and instrumentation fixation. Of 13 patients, 7 were male and 6 were female with an average age of 23.5 years (range, 14-49 years). The disease duration was 13-38 months (mean, 19 months). The Cobb angle of kyphosis was (65.23 ± 7.95)°. The visual analogue scale score (VAS) was 7.38 ± 0.31. In 13 patients with incomplete paraplegia, 1 case was classified as Frankel grade B, 7 cases as grade C, and 5 cases as grade D. The lesion involved 2 vertebrae bodies in 7 cases (T8, 9 in 1 case, T11, 12 in 2 cases, and T12, L1 in 4 cases), 3 vertebrae bodies in 4 cases (T10-12 in 2 cases, T9-11 in 1 case, and T11-L1 in 1 case), and 4 vertebrae bodies in 2 cases (T4-7 in 1 case and T6-9 in 1 case). Imaging examination showed paravertebral abscess in 10 cases. Healing of incision by first intention was obtained in all patients. The neurological injury and pulmonary infection occurred in 3 cases and 2 cases respectively, which were cured after symptomatic treatment. Thirteen patients were followed up 12-48 months (mean, 17 months). The erythrocyte sedimentation rate restored to normal level in all cases at 3-7 months after operation. All the patients achieved bony fusion at 10-20 months (mean, 14 months) after operation. No fixation loosening, displacement, or fracture occurred during follow-up. Common toxic symptom of tuberculosis disappeared, and there was no recurrence of local tuberculosis. The Cobb angle of kyphosis was corrected to (22.38 ± 1.76)° at 1 week and (22.15 ± 1.83)° at last follow-up, showing significant difference when compared with

    Pyrazinamide is a key drug in the first-line treatment regimen for tuberculosis, with a potent sterilizing effect. Although low pyrazinamide peak serum concentrations (C max ) are associated with poor treatment outcomes, many resource-constrained settings do not have sufficient laboratory capacity to support therapeutic drug monitoring (TDM). The objective of this study was to determine whether a colorimetric test of urine can identify tuberculosis patients with adequate pyrazinamide exposures, as defined by serum C max above a target threshold. In the derivation study of healthy volunteers, three dose sizes of pyrazinamide were evaluated, and intensive pharmacokinetic blood sampling was performed over an 8-h period, with a timed urine void at 4h post-dosing. Pyrazinamide in urine was isolated by spin column centrifugation with an exchange resin, followed by colorimetric analysis; the absorbance peak at 495nm was measured. The urine assay was then evaluated in a study of 39 HIV/tuberculosis patients in Botswana enrolled in an intensive pharmacokinetic study. Receiver operating characteristics (ROC) curves were used to measure diagnostic accuracy. The guideline-recommended pyrazinamide serum C max target of 35mg/l was evaluated in the primary analysis; this target was found to be predictive of favorable outcomes in a clinical study. Following this, a higher serum C max target of 58mg/l was evaluated in the secondary analysis. At the optimal cut-off identified in the derivation sample, the urine colorimetric assay was 97% sensitive and 50% specific to identify 35 of 39 HIV/tuberculosis patients with pharmacokinetic target attainment, with an area under the ROC curve of 0.81 (95% confidence interval 0.60-0.97). Diagnostic accuracy was lower at the 58mg/l serum C max target, with an area under the ROC curve of 0.68 (95% confidence interval 0.48-0.84). Men were less likely than women to attain either serum pharmacokinetic target. The urine colorimetric assay was

    To evaluate the prevalence of pulmonary function abnormalities and to investigate the factors affecting lung function in patients treated for pulmonary tuberculosis. A total of 214 consecutive patients (132 men and 82 women; 20-82 years of age), treated for pulmonary tuberculosis and followed at a local dispensary, underwent spirometry and plethysmography at least one year after treatment. Pulmonary impairment was present in 102 (47.7%) of the 214 patients evaluated. The most common functional alteration was obstructive lung disease (seen in 34.6%). Of the 214 patients, 60 (28.0%) showed reduced pulmonary function (FEV1 below the lower limit of normal). Risk factors for reduced pulmonary function were having had culture-positive pulmonary tuberculosis in the past, being over 50 years of age, having recurrent tuberculosis, and having a lower level of education. Nearly half of all tuberculosis patients evolve to impaired pulmonary function. That underscores the need for pulmonary function testing after the end of treatment. Avaliar a prevalência de alterações da função pulmonar e investigar os fatores que afetam a função pulmonar em pacientes tratados para tuberculose pulmonar. Um total de 214 pacientes consecutivos (132 homens e 82 mulheres; 20-82 anos de idade), tratados para tuberculose pulmonar e acompanhados em um dispensário local, foi submetido a espirometria e pletismografia pelo menos um ano após o tratamento. O comprometimento pulmonar estava presente em 102 (47,7%) dos 214 pacientes avaliados. A alteração funcional mais comum foi o distúrbio ventilatório obstrutivo (observado em 34,6%). Dos 214 pacientes, 60 (28,0%) apresentaram função pulmonar reduzida (VEF1 abaixo do limite inferior de normalidade). Os fatores de risco para função pulmonar reduzida foram tuberculose pulmonar com cultura positiva no passado, idade acima de 50 anos, recidiva de tuberculose e menor nível de escolaridade.

    One of the most serious problems for tuberculosis (TB) control is non-adherence to TB treatment. We studied the factors influencing non-adherence to TB treatment in Indonesia to inform TB treatment adherence strategies. We con- ducted semi-structured interviews with non-adherent patients and key informants in Jepara, Central Java, Indonesia. Three major themes were found in reasons for non-adherence to TB treatment: 1) knowledge about TB, 2) knowledge about TB treatment and 3) choosing and changing a health care treatment facility. Respondents had an inadequate knowledge about TB and its treatment. Feeling healthy and having financial problems were the most common reasons for TB treatment non-adherence. Respondents sought treatment from many different health care providers, and often changed the treatment facility location. TB treatment adherence might improve by providing better education about the disease and its treatment to those undergoing treatment. Providing information about where to receive treatment and that treatment is free could also improve compliance.

    Tuberculosis (TB) health care facilities throughout Georgia. To describe smoking behaviors among health care workers (HCWs) at TB facilities and determine HCWs' knowledge and beliefs regarding the impact of tobacco use on anti-tuberculosis treatment. Cross-sectional survey from May to December 2014 in Georgia. Adult HCWs (age 18 years) at TB facilities were eligible. We administered a 60-question anonymous survey about tobacco use and knowledge of the effect of smoking on anti-tuberculosis treatment. Of the 431 HCWs at TB facilities who participated, 377 (87.5%) were female; the median age was 50 years (range 20-77). Overall, 59 (13.7%) HCWs were current smokers and 35 (8.1%) were past smokers. Prevalence of current smoking was more common among physicians than among nurses (18.6% vs. 7.9%, P tuberculosis treatment, and only 25.3% of physicians/nurses received formal training in smoking cessation approaches. Physicians who smoked were significantly more likely to believe that smoking does not impact anti-tuberculosis treatment than non-smoking physicians (aOR 5.11, 95%CI 1.46-17.90). Additional education about the effect of smoking on TB treatment outcomes is needed for staff of TB health care facilities in Georgia. Nurses and physicians need more training about smoking cessation approaches for patients with TB.

    Full Text Available We report a case of 23-year-old male patient with tuberculosis verrucous cutis on the foot for a duration of six months without responding to routine treatment. Tuberculosis is a common disease worldwide. Extrapulmonary tuberculosis contributes to 10% of cases. Cutaneous tuberculosis occupies a small spectrum of extrapulmonary tuberculosis. Tuberculosis verrucosa cutis is an exogenous infection occurring in a previously sensitized patient by direct inoculation of the organism. It occurs in sensitized patients with a moderate to high immune response. The diagnosis in our patient was confirmed by history, clinical examination, histopathological examination and the patient’s response to anti-tuberculous therapy.

    Despite significant efforts to improve the treatment of tuberculosis (TB), it remains a prevalent infectious disease worldwide owing to the limitations of current TB therapeutic regimens. Recent work on novel TB treatment strategies has suggested that directly targeting host factors may be beneficial for TB treatment. Such strategies, termed host-directed therapeutics (HDTs), focus on host-pathogen interactions. HDTs may be more effective than the currently approved TB drugs, which are limited by the long durations of treatment needed and the emergence of drug-resistant strains. Targets of HDTs include host factors such as cytokines, immune checkpoints, immune cell functions, and essential enzyme activities. This review article discusses examples of potentially promising HDTs and introduces novel approaches for their development.

    Full Text Available Objectives: The aim of this study was to evaluate whether rifabutin can improve treatment outcomes in patients with rifabutin-sensitive MDR-TB. Methods: A retrospective cohort study was performed on 76 patients with rifabutin-sensitive MDR-TB who were treated with or without rifabutin between 2006 and 2011. Results: Overall, 75% (57/76 of patients achieved favorable outcomes, including cure (53/76, 70% and treatment completion (4/76, 5%. In contrast, 25% (19/76 had unfavorable treatment outcomes, which included treatment failure (6/76, 8%, death (2/76, 3%, loss to follow-up (4/76. 5%, and no evaluation due to transfer to other institutions (7/76, 9%. Rifabutin was given to 52 (68% of the 76 patients with rifabutin-sensitive MDR-TB. Although favorable treatment outcomes were more frequent in patients who received rifabutin [81% (42/52] than in those who did not receive rifabutin [63% (15/24], this difference was not statistically significant (P = 0.154. However, in multivariable regression logistic analysis, use of rifabutin was significantly associated with favorable treatment outcomes in patients with rifabutin-sensitive MDR-TB (adjusted odds ratio = 9.80, 95% confidence interval = 1.65–58.37, P = 0.012. Conclusions: These results suggest that the use of rifabutin can improve treatment outcomes in patients with rifabutin-sensitive MDR-TB.

    Full Text Available Conventional analytic methods used for tuberculosis (TB outcomes research use standardized outcomes definitions and assess safety and efficacy separately. These methods are subject to important limitations. Conventionally utilized outcome definitions fail to capture important aspects of patients' treatment experience and obscure meaningful differences between patients.Assessing safety and efficacy separately fails to yield an objective risk–benefit comparison to guide clinical practice. We propose to address these issues through an analytic approach based on prioritized outcomes. This approach enables a more comprehensive and integrated assessment of TB interventions. It simultaneously considers a “totality of outcomes”, including clinical benefit, adverse events, and quality of life. These composite outcomes are ranked terms of overall desirability and compared using statistical methods for ordinal outcomes. Here we discuss the application of this approach to TB research, the considerations involved with prioritizing TB treatment outcomes, and the statistical methods involved in comparing prioritized outcomes.

    Fifty-four juvenile cases under 18 years of age with thoracic and lumbar spinal tuberculosis underwent focus debridement, deformity correction, bone graft fusion, and internal fixation. The treatment effects, complications, and reasons were analyzed retrospectively. There were 54 juvenile cases under 18 years of age with thoracolumbar spinal tuberculosis. The average age was 9.2 years old, and the sample comprised 38 males and 16 females. The disease types included 28 thoracic cases, 17 thoracolumbar cases, and 9 lumbar cases. Nerve function was evaluated with the Frankel classification. Thirty-six cases were performed with focus debridement and deformity correction and were supported with allograft or autograft in mesh and fixed with pedicle screws from a posterior approach. Eight cases underwent a combined anterior and posterior surgical approach. Nine cases underwent osteotomy and deformity correction, and one case received focus debridement. The treatment effects, complications, and bone fusions were tracked for an average of 52 months. According to the Frankel classification, paralysis was improved from 3 cases of B, 8 cases of C, 18 cases of D, and 25 cases of E preoperatively. This improvement was found in 3 cases of C, 6 cases of D, and 45 cases of E at a final follow-up postoperatively. No nerve dysfunction was aggravated. VAS was improved from 7.8 ± 1.7 preoperatively to 3.2 ± 2.1 at final follow-up postoperatively. ODI was improved from 77.5 ± 17.3 preoperatively to 28.4 ± 15.9 at final follow-up postoperatively. Kyphosis Cobb angle improved from 62.2° ± 3.7° preoperatively to 37° ± 2.4° at final follow-up postoperatively. Both of these are significant improvements, and all bone grafts were fused. Complications related to the operation occurred in 31.5% (17/54) of cases. Six cases suffered postoperative aggravated kyphosis deformity, eight cases suffered proximal kyphosis deformity, one case suffered pedicle penetration

    Tuberculosis (TB) control programs face the challenges of decreasing incidence, mortality rates, and drug resistance while increasing treatment adherence. The Brazilian TB control program recommended the decentralization of patient care as a strategy for combating the disease. This study evaluated the performance of this policy in an area with high default rates, comparing epidemiological and operational indicators between two similar municipalities. This study analyzed epidemiological and operational indicators on new cases of pulmonary tuberculosis reported in the Brazilian Notifiable Diseases Information System between 2006 and 2015. In addition, to characterize differences between the populations of the two studied municipalities, a prospective cohort study was conducted between 2014 and 2015, in which patients with new cases of culture-confirmed pulmonary tuberculosis were interviewed and monitored until the disease outcome. A descriptive analysis, the chi-square test, and a Poisson regression model were employed to compare TB treatment outcomes and health care indicators between the municipalities. Two thousand three hundred nine cases were evaluated, of which 207 patients were interviewed. Over the 2006-2015 period, TB incidence per 100,000 population in the municipality with decentralized care was significantly higher (39%, 95% CI 27-49%) in comparison to that of the municipality with centralized care. TB treatment default rate (45%, 95% CI 12-90%) was also higher in the municipality with decentralized care. During the two-year follow-up, significant differences were found between patients in centralized care and those in decentralized care regarding treatment success (84.5 vs. 66.1%), treatment default (10.7 vs. 25.8%), illicit drug use (27.7 vs. 45.9%), and homelessness (3.6 vs. 12.9%). The operational indicators revealed that the proportion of control smear tests, medical imaging, and HIV tests were all significantly higher in the centralized care

    2011-01-01

    Background Successful treatment of tuberculosis (TB) involves taking anti-tuberculosis drugs for at least six months. Poor adherence to treatment means patients remain infectious for longer, are more likely to relapse or succumb to tuberculosis and could result in treatment failure as well as foster emergence of drug resistant tuberculosis. Kenya is among countries with high tuberculosis burden globally. The purpose of this study was to determine the duration tuberculosis patients stay in treatment before defaulting and factors associated with default in Nairobi. Methods A Case-Control study; Cases were those who defaulted from treatment and Controls those who completed treatment course between January 2006 and March 2008. All (945) defaulters and 1033 randomly selected controls from among 5659 patients who completed treatment course in 30 high volume sites were enrolled. Secondary data was collected using a facility questionnaire. From among the enrolled, 120 cases and 154 controls were randomly selected and interviewed to obtain primary data not routinely collected. Data was analyzed using SPSS and Epi Info statistical software. Univariate and multivariate logistic regression analysis to determine association and Kaplan-Meier method to determine probability of staying in treatment over time were applied. Results Of 945 defaulters, 22.7% (215) and 20.4% (193) abandoned treatment within first and second months (intensive phase) of treatment respectively. Among 120 defaulters interviewed, 16.7% (20) attributed their default to ignorance, 12.5% (15) to traveling away from treatment site, 11.7% (14) to feeling better and 10.8% (13) to side-effects. On multivariate analysis, inadequate knowledge on tuberculosis (OR 8.67; 95% CI 1.47-51.3), herbal medication use (OR 5.7; 95% CI 1.37-23.7), low income (OR 5.57, CI 1.07-30.0), alcohol abuse (OR 4.97; 95% CI 1.56-15.9), previous default (OR 2.33; 95% CI 1.16-4.68), co-infection with Human immune-deficient Virus (HIV) (OR 1

    The number of multidrug-resistant tuberculosis patients is increasing each year in many countries all around the globe. Malaysia has no exception in facing this burdensome health problem. We aimed to investigate the factors that contribute to the occurrence of multidrug-resistant tuberculosis among Malaysian tuberculosis patients. An unmatched case-control study was conducted among tuberculosis patients who received antituberculosis treatments from April 2013 until April 2014. Cases are those diagnosed as pulmonary tuberculosis patients clinically, radiologically, and/or bacteriologically, and who were confirmed to be resistant to both isoniazid and rifampicin through drug-sensitivity testing. On the other hand, pulmonary tuberculosis patients who were sensitive to all first-line antituberculosis drugs and were treated during the same time period served as controls. A total of 150 tuberculosis patients were studied, of which the susceptible cases were 120. Factors found to be significantly associated with the occurrence of multidrug-resistant tuberculosis are being Indian or Chinese (odds ratio 3.17, 95% confidence interval 1.04-9.68; and odds ratio 6.23, 95% confidence interval 2.24-17.35, respectively), unmarried (odds ratio 2.58, 95% confidence interval 1.09-6.09), living in suburban areas (odds ratio 2.58, 95% confidence interval 1.08-6.19), are noncompliant (odds ratio 4.50, 95% confidence interval 1.71-11.82), were treated previously (odds ratio 8.91, 95% confidence interval 3.66-21.67), and showed positive sputum smears at the 2nd (odds ratio 7.00, 95% confidence interval 2.46-19.89) and 6th months of treatment (odds ratio 17.96, 95% confidence interval 3.51-91.99). Living in suburban areas, positive sputum smears in the 2nd month of treatment, and was treated previously are factors that independently contribute to the occurrence of multidrug-resistant tuberculosis.

    All individuals reported as being treated for pulmonary tuberculosis (PTB) among citizens of Taipei City, Taiwan, in 2003. To investigate risk factors associated with treatment interruption for at least 2 consecutive months and death. The outcome of PTB cases was determined by consulting medical charts. Of 1127 PTB patients registered, 824 (73.1%) were successfully treated, 189 (16.8%) died, 65 (5.8%) interrupted treatment, 17 (1.5%) were still on treatment 15 months after commencing treatment and 32 (2.8%) failed. The only significant factor associated with treatment interruption was visits to other health facilities after commencing tuberculosis (TB) treatment. TB patients had a standardised mortality ratio of 8.7 (95%CI 7.5-10.0). Factors significantly associated with death were age (adjusted hazard ratio [adjHR] 1.06. 95%CI 1.05-1.08), sputum culture not performed/unknown (adjHR 2.07, 95%CI 1.47-2.92), and comorbidity with respiratory disease (adjHR 1.68, 95%CI 1.24-2.27), infectious disease (adjHR 2.80, 95%CI 2.07-3.78), renal disease (adjHR 2.58, 95%CI 1.82-3.66) or cancer (adjHR 3.31, 95%CI 2.35-4.65), compared with other patients. Visits to other health facilities were associated with interruption of treatment for at least 2 months. A high proportion of deaths was due to old age and comorbidity.

    Full Text Available Biomarkers associated with response to therapy in tuberculosis could have broad clinical utility. We postulated that the frequency of Mycobacterium tuberculosis (Mtb specific CD8(+ T cells, by virtue of detecting intracellular infection, could be a surrogate marker of response to therapy and would decrease during effective antituberculosis treatment.We sought to determine the relationship of Mtb specific CD4(+ T cells and CD8(+ T cells with duration of antituberculosis treatment.We performed a prospective cohort study, enrolling between June 2008 and August 2010, of HIV-uninfected Ugandan adults (n = 50 with acid-fast bacillus smear-positive, culture confirmed pulmonary TB at the onset of antituberculosis treatment and the Mtb specific CD4(+ and CD8(+ T cell responses to ESAT-6 and CFP-10 were measured by IFN-γ ELISPOT at enrollment, week 8 and 24.There was a significant difference in the Mtb specific CD8(+ T response, but not the CD4(+ T cell response, over 24 weeks of antituberculosis treatment (p<0.0001, with an early difference observed at 8 weeks of therapy (p = 0.023. At 24 weeks, the estimated Mtb specific CD8(+ T cell response decreased by 58%. In contrast, there was no significant difference in the Mtb specific CD4(+ T cell during the treatment. The Mtb specific CD4(+ T cell response, but not the CD8(+ response, was negatively impacted by the body mass index.Our data provide evidence that the Mtb specific CD8(+ T cell response declines with antituberculosis treatment and could be a surrogate marker of response to therapy. Additional research is needed to determine if the Mtb specific CD8(+ T cell response can detect early treatment failure, relapse, or to predict disease progression.

    Immune-modulating drugs that target myeloid-derived suppressor cells or stimulate natural killer T cells have been shown to reduce mycobacterial loads in tuberculosis (TB). We aimed to determine if a combination of these drugs as adjunct immunotherapy to conventional antibiotic treatment could also increase therapeutic efficacy against TB. In our model of pulmonary TB in mice, we applied treatment with isoniazid, rifampicin, and pyrazinamide for 13 weeks alone or combined with immunotherapy consisting of all-trans retinoic acid, 1,25(OH) 2 -vitamin D3, and α-galactosylceramide. Outcome parameters were mycobacterial load during treatment (therapeutic activity) and 13 weeks after termination of treatment (therapeutic efficacy). Moreover, cellular changes were analyzed using flow cytometry and cytokine expression was assessed at the mRNA and protein levels. Addition of immunotherapy was associated with lower mycobacterial loads after 5 weeks of treatment and significantly reduced relapse of disease after a shortened 13-week treatment course compared with antibiotic treatment alone. This was accompanied by reduced accumulation of immature myeloid cells in the lungs at the end of treatment and increased TNF-α protein levels throughout the treatment period. We demonstrate, in a mouse model of pulmonary TB, that immunotherapy consisting of three clinically approved drugs can improve the therapeutic efficacy of standard antibiotic treatment.

Newly diagnosed (confirmed by smear and culture) pulmonary tuberculosis patients were selected, and those who accepted to be included in the study, were admitted to the National Institute of Pneumology "Marius Nasta" between August 2001 and September 2002. At the time of admission, they were randomized into two groups: 20 patients received fixed drug combination RMP300 HIN150, and 18 patients received RMP and HIN in single drug tablets (2 patients were excluded). The follow-up of the patients was for one year from the date of enclosure. The smear conversion rate was 83,3% for the patients using single drug tablets, and 70% for those using fixed drug combination, motivated with some more severe TB patterns. The success rate was 100% for all TB patients. Although the present study was done for few patients, we can say that it demonstrated the same efficiency of fixed drug combination produced in Romania, with the single drug tablets, and it suggests a better compliance to treatment with a lower price.

    Tuberculosis (TB) is an infectious and transmissible disease that is caused by Mycobacterium tuberculosis and primarily affects the lungs, although it can affect other organs and systems. The pulmonary presentation of TB, in addition to being more frequent, is also the most relevant to public health because it is primarily responsible for the transmission of the disease. The to their low World Health Organization (WHO) recommends a combined therapeutic regimen of several drugs, such as rifampicin (RIF), isoniazid (INH), pyrazinamide (PZA) and ethambutol (ETB). These drugs have low plasma levels after oral administration, due to their low water solubility, poor permeability and ability to be rapidly metabolized by the liver and at high concentrations. Furthermore, they have short t₁/₂ (only 1-4 hours) indicating a short residence in the plasma and the need for multiple high doses, which can result in neurotoxicity and hepatotoxicity. Nanotechnology drug delivery systems have considerable potential for the treatment of TB. The systems can also be designed to allow for the sustained release of drugs from the matrix and drug delivery to a specific target. These properties of the systems enable the improvement of the bioavailability of drugs, can reduce the dosage and frequency of administration, and may solve the problem of non-adherence to prescribed therapy, which is a major obstacle to the control of TB. The purpose of this study was to systematically review nanotechnology-based drug delivery systems for the treatment of TB.

    Full Text Available Abstract Background Tuberculosis (TB kills one child every 5 min. Childhood TB is given low priority in most national health programmes particularly in TB-endemic areas. TB among children is an indicator of a recent transmission of the disease in the community. Treatment outcome results serve as a proxy of the quality of treatment provided by a health care system. In Ethiopia, data on treatment outcomes of childhood TB are limited. The aim of the study was to determine the treatment outcomes of childhood TB in a hospital setting in Addis Ababa. Methods The study was conducted during June to August 2014. The data of 491 children treated for TB in Zewditu Memorial Hospital during a 5 year (2009–2013 was analysed. TB was diagnosed using standard methods. Demographic and clinical data including type of TB, TB-HIV co-infection and treatment outcomes were collected from registry of the TB clinic. Treatment outcome definitions are used according to the World Health Organization. Results Of the 491 children, 272(55.4 % were females, 107(21.8 % were under 5 year old, 454(92.5 % of them were new cases. The types of TB were extra-pulmonary tuberculosis (EPTB 243(49.5 % and 248(50.5 % pulmonary tuberculosis (PTB. Of the PTB cases, 42(16.9 % were sputum smear positive. Of the 291 children tested for HIV, 82(28.2 % were positive. The overall treatment success rate was 420(85.5 % and the poor treatment outcome was 71(14.5 %.

    Full Text Available Background: Multi-drug resistant tuberculosis (TB is a rising peril of the TB control in India caused mostly by incomplete treatment. Aim: The aim was to assess the treatment interruption among pulmonary TB (PTB patients. Materials and Methods: A cross-sectional study was carried out for a period of 9 months among PTB patients. Patients admitted with active pulmonary Koch′s and history of anti-TB treatment (ATT for 1-month or more from any source and who returns to treatment after not taking ATT consecutively for 2 months or more were included in the study. The data were collected from the patients or their caretakers to obtain the source of treatment given previously before default, number of treatment interruptions, phase and reasons for treatment interruption treatment. Results: A total of 107 defaulters were identified during the study period. In the present study, 62.6% of the patients interrupted treatment only once, 55.34% of the patient′s early continuation (3-4 months treatment, and 47.66% of the patient′s only one reason for the treatment interruptions during the course of the treatment. The most common reason for the treatment interruptions were felt well with TB treatment (29.53% followed by side effects (16.06%, lack of money (8.29%, and other reasons. Conclusion: The study revealed that most of the defaulters were in the age group between 35 and 60 years, male gender, illiterates, daily wage labor, and married. The treatment interruptions were minimized by putting the efforts to improve direct supervision; pretreatment counseling and retrieve treatment interrupters were recommended.

Se recomienda elaborar una estrategia de intervención que contemple un proyecto capacitante, encaminado a elevar la competencia profesional del personal sanitario en relación con la asistencia integral incluida en el Programa Nacional de Control de la Tuberculosis.A cross-sectional and descriptive study was conducted to characterize patients with pulmonary tuberculosis whose sputa were positive for acid-alcohol resistant bacilli, in a general population of Santiago de Cuba municipality, from 2003 to 2007, who opted for the strategy of strictly monitored and shortened treatment. Male sex, young adults as well as risk factors: smoking habit, alcoholism and history of contacts with people affected by this disease prevailed in the case material. Primary health care neither meet the operational indicator of the diagnosis of these patients nor the monthly bacilloscopy. It is recommended to develop an intervention strategy that includes a project aimed at improving the professional competence of health personnel with regard to comprehensive care included in the National Program of Tuberculosis Control.

    Full Text Available It is estimated that one third of the world’s population is infected with Mycobacterium tuberculosis (Mtb. This astounding statistic, in combination with costly and lengthy treatment regimens make the development of therapeutic vaccines paramount for controlling the global burden of tuberculosis. Unlike prophylactic vaccination, therapeutic immunization relies on the natural pulmonary infection with Mtb as the mucosal prime that directs boost responses back to the lung. The purpose of this work was to determine the protection and safety profile over time following therapeutic administration of our lead Mtb vaccine candidate, ID93 with a synthetic TLR4 agonist (glucopyranosyl lipid adjuvant in a stable emulsion (GLA-SE, in combination with rifampicin, isoniazid, and pyrazinamide (RHZ drug treatment. We assessed the host inflammatory immune responses and lung pathology 7–22 weeks post infection, and determined the therapeutic efficacy of combined treatment by enumeration of the bacterial load and survival in the SWR/J mouse model. We show that drug treatment alone, or with immunotherapy, tempered the inflammatory responses measured in brochoalveolar lavage fluid and plasma compared to untreated cohorts. RHZ combined with therapeutic immunizations significantly enhanced TH1-type cytokine responses in the lung over time, corresponding to decreased pulmonary pathology evidenced by a significant decrease in the percentage of lung lesions and destructive lung inflammation. These data suggest that bacterial burden assessment alone may miss important correlates of lung architecture that directly contribute to therapeutic vaccine efficacy in the preclinical mouse model. We also confirmed our previous finding that in combination with antibiotics therapeutic immunizations provide an additive survival advantage. Moreover, therapeutic immunizations with ID93/GLA-SE induced differential T cell immune responses over the course of infection that correlated

    Background Despite being curable, tuberculosis is still a stigmatized disease. Not only is TB patients’ suffering due to its clinical manifestations, but also because of society’s prejudice, embarrassing situations, and even self-discrimination. This study aims to investigate psychosocial experiences of patients who have completed tuberculosis treatment in São Carlos a municipality in the interior of São Paulo State, Brazil. Methods This study, of a clinical-qualitative nature, sought to understand the meanings provided by the participants themselves. Fifteen individuals, who had successfully completed tuberculosis treatment, participated in this research. The sample size was established using the information saturation criterion. Data were collected by means of interviews with in-depth open-ended questions. Data were treated by categorizing and analyzing content according to themes. Results Regardless of all progress, this study found that TB still causes patients to suffer from fear of transmission, social prejudice, and death. Despite the fact that the emotional support provided by families and healthcare professionals is considered essential to treatment adherence and completion, participants in this study reveal that friends and colleagues have distanced themselves from them for fear of contagion and/or prejudice. Ignorance about the disease and its transmission modes can be found in the interviewees’ statements, which seems to indicate that they have become vectors of transmission of stigma themselves. Patients’ medical leave from work during treatment may be due to both their health conditions and their attempt to avoid social/emotional embarrassment. There are accounts that TB has caused psychosocial damage to patients’ lives and that they feel more fatigue and lassitude and have begun to pay more attention to their own health. Conclusions Healthcare workers should be aware of the ways TB treatment affect patients’ psychosocial life and

    Background Tuberculosis (TB) patients face substantial delays prior to treatment initiation, and out of pocket (OOP) expenditures often surpass the economic productivity of the household. We evaluated the pre-diagnostic cost and health seeking behaviour of new adult pulmonary TB patients registered at Primary Health Centres (PHCs) in Vellore district, Tamil Nadu, India. Methods This descriptive study, part of a randomised controlled trial conducted in three rural Tuberculosis Units from Dec 2012 to Dec 2015, collected data on number of health facilities, dates of visits prior to the initiation of anti-tuberculosis treatment, and direct OOP medical costs associated with TB diagnosis. Logistic regression analysis examined the factors associated with delays in treatment initiation and OOP expenditures. Results Of 880 TB patients interviewed, 34.7% presented to public health facilities and 65% patients sought private health facilities as their first point of care. The average monthly individual income was $77.79 (SD 57.14). About 69% incurred some pre-treatment costs at an average of $39.74. Overall, patients experienced a median of 6 days (3–11 IQR) of time to treatment initiation and 21 days (10–30 IQR) of health systems delay. Age ≤ 40 years (aOR: 1.73; CI: 1.22–2.44), diabetes (aOR: 1.63; CI: 1.08–2.44) and first visit to a private health facility (aOR: 17.2; CI: 11.1–26.4) were associated with higher direct OOP medical costs, while age ≤ 40 years (aOR: 0.64; CI: 0.48–0.85) and first visit to private health facility (aOR: 1.79, CI: 1.34–2.39) were associated with health systems delay. Conclusion The majority of rural TB patients registering at PHCs visited private health facilities first and incurred substantial direct OOP medical costs and delays prior to diagnosis and anti-tuberculosis treatment initiation. This study highlights the need for PHCs to be made as the preferred choice for first point of contact, to combat TB more efficiently. PMID

    Aim: We describe the role of various imaging modalities in the diagnosis and follow up of calcaneal tuberculosis. Materials and methods: Six patients (5 males, 1 female; age range 16-49 years) presented with heel pain. All patients underwent routine laboratory and radiological investigations e.g. radiographs, MRI and skeletal scintigraphy as part of initial diagnostic work-up. In all patients the diagnosis of tuberculosis was confirmed based on histopathology or culture. Standard multi-drug anti-tubercular therapy (ATT) was administered for 15 months. All patients were subsequently followed up with clinical evaluation, laboratory investigations and imaging. Skeletal scintigraphy, MRI and radiographs were repeated at 12 to 15 months from the initiation of anti-tubercular treatment in all patients. Results: Five out of six patients had lytic lesions at presentation on radiographs. Four of these 5 patients also had surrounding sclerosis. Follow-up radiographs obtained 12-15 months after starting ATT, showed an increase in surrounding sclerosis with progressive reduction in area of osteopenia in four and mild sclerotic changes in one. In the remaining one patient radiograph were normal both at presentation and follow up. Three phase bone scintigraphy revealed increased blood flow and blood pool activity and 'hot spots' in 5 and a central photopenic area in the calcaneum in one patient at the time of diagnosis. After starting ATT, significant reduction in vascularity and reactive bone changes in 5 patients and mild improvement in one patient. MRI was done in three patients, which revealed hyperintense lesion with erosion of the superior articular surface in 2 and 'Bull's eye' lesion with a hypointense centre and a surrounding hyperintense rim on post contrast T1W images in one patient. Follow-up MRI showed intermediate signal intensity on T2 weighted images that corresponded to caseous necrosis and high signal intensity related to granulomas or effusion. Conclusion

    The Northern Cape Province, Republic of South Africa. To determine the effect of patient choice of treatment delivery option on the treatment outcomes of tuberculosis (TB) patients in a high burden setting under actual programme conditions. Cohort study involving 769 new and retreatment TB patients recruited from 45 randomly selected clinics. Patients were interviewed and subsequent follow-up was done through regular visits to the clinics to check progress through formal health records. There was a statistically significant difference (P < 0.001) between the treatment outcome of new patients (70% successful) and re-treatment patients (54% successful). Direct observation of treatment (DOT) was found to have no effect on the treatment outcome of new patients (P = 0.875), but re-treatment patients were found to fare better with than without DOT (OR 14.2, 95% CI 4.18-53.14, P < 0.001). The results obtained for new patients are similar to those of two recent randomised controlled trials on DOT. This study revealed that for new patients, undue emphasis on universal DOT might be unnecessary. It would perhaps be more beneficial to target supervision at those patients who are most likely to benefit from it (i.e., re-treatment patients). This is of particular relevance in high burden, resource-limited settings where universal DOT for all TB patients is generally unfeasible.

    In Morocco, tuberculosis (TB) treatment default is increasing in some urban areas. To provide a detailed description of factors that contribute to patient default and solutions from the point of view of health care professionals who participate in TB care. In-depth interviews were conducted with 62 physicians and nurses at nine regional public pulmonary clinics and local health clinics. Participants had a median of 24 years of experience in health care. Treatment default was seen as a result of multilevel factors related to the patient (lack of means, being a migrant worker, distance to treatment site, poor understanding of treatment, drug use, mental illness), medical team (high patient load, low motivation, lack of resources for tracking defaulters), treatment organization (poor communication between treatment sites, no systematic strategy for patient education or tracking, incomplete record keeping), and health care system and society. Tailored recommendations for low- and higher-cost interventions are provided. Interventions to enhance TB treatment completion should take into account the local context and multilevel factors that contribute to default. Qualitative studies involving health care workers directly involved in TB care can be powerful tools to identify contributing factors and define strategies to help reduce treatment default.

Understanding the factors that influence adherence behavior is essential in predicting which individuals and communities are at risk of nonadherence. This is necessary for supporting resource allocation and intervention planning in disease control programs. Currently, there is no known concrete and unambiguous computational representation of factors that influence tuberculosis (TB treatment adherence behavior that is useful for prediction. This study developed a computer-based conceptual model for capturing and structuring knowledge about the factors that influence TB treatment adherence behavior in sub-Saharan Africa (SSA.Methods: An extensive review of existing categorization systems in the literature was used to develop a conceptual model that captured scientific knowledge about TB adherence behavior in SSA. The model was formalized as an ontology using the web ontology language. The ontology was then evaluated for its comprehensiveness and applicability in building predictive models. Conclusion: The outcome of the study is a novel ontology-based approach for curating and structuring scientific knowledge of adherence behavior in patients with TB in SSA. The ontology takes an evidence-based approach by explicitly linking factors to published clinical studies. Factors are structured around five dimensions: factor type, type of effect, regional variation, cross-dependencies between factors, and treatment phase. The ontology is

    Tuberculosis (TB) is a major contributor to the global burden of disease and has received considerable attention in recent years, particularly in low- and middle-income countries where it is closely associated with HIV/AIDS. Poor adherence to treatment is common despite various interventions aimed at improving treatment completion. Lack of a comprehensive and holistic understanding of barriers to and facilitators of, treatment adherence is currently a major obstacle to finding effective solutions. The aim of this systematic review of qualitative studies was to understand the factors considered important by patients, caregivers and health care providers in contributing to TB medication adherence. We searched 19 electronic databases (1966-February 2005) for qualitative studies on patients', caregivers', or health care providers' perceptions of adherence to preventive or curative TB treatment with the free text terms "Tuberculosis AND (adherence OR compliance OR concordance)". We supplemented our search with citation searches and by consulting experts. For included studies, study quality was assessed using a predetermined checklist and data were extracted independently onto a standard form. We then followed Noblit and Hare's method of meta-ethnography to synthesize the findings, using both reciprocal translation and line-of-argument synthesis. We screened 7,814 citations and selected 44 articles that met the prespecified inclusion criteria. The synthesis offers an overview of qualitative evidence derived from these multiple international studies. We identified eight major themes across the studies: organisation of treatment and care; interpretations of illness and wellness; the financial burden of treatment; knowledge, attitudes, and beliefs about treatment; law and immigration; personal characteristics and adherence behaviour; side effects; and family, community, and household support. Our interpretation of the themes across all studies produced a line

    There is uncertainty as to the optimal therapeutic concentrations of anti-tuberculosis drugs to achieve cure. To characterise the use of therapeutic drug monitoring (TDM), and identify risk factors and outcomes for those with concentrations below the drug interval. Patients treated for tuberculosis (TB) who had rifampicin (RMP) or isoniazid (INH) concentrations measured between 1 January 2005 and 31 December 2012 were studied retrospectively. Matched concentrations and drug dosing time were assessed according to contemporary regional drug intervals (RMP > 6 μmol/l, INH > 7.5 μmol/l) and current international recommendations (RMP > 10 μmol/l, INH > 22 μmol/l). Outcomes were assessed using World Health Organization criteria. Of 865 patients, 121 had concentrations of either or both medications. RMP concentrations were within the regional drug intervals in 106/114 (93%) and INH in 91/100 (91%). Concentrations were within international drug intervals for RMP in 76/114 (67%) and INH in 53/100 (53%). Low weight-based dose was the only statistically significant risk factor for concentrations below the drug interval. Of the 35 patients with low concentrations, 21 were cured, 9 completed treatment and 5 transferred out. There were no relapses during follow-up (mean 66.5 months). There were no clinically useful characteristics to guide use of TDM. Many patients had concentrations below international therapeutic intervals, but were successfully treated.

    Full Text Available A 13-year-old girl was admitted to our department with a history of severe pain of her left axilla and fever. On physical examination, a block of lymph nodes in her left axilla, diffuse papular rash, and red-violet swelling of her supraclavicular and subclavian region were noted. Imaging investigations revealed left axillar and supraclavicular lymphadenopathy and a small nodular shade in the upper lobe of her left lung. A biopsy from an axillary lymph node established the diagnosis of anaplastic large cell lymphoma (ALCL, whereas DNA of Mycobacterium tuberculosis was detected by polymerase chain reaction (PCR in the same tissue biopsy. Patient was started on chemotherapy for ALCL and achieved remission of all initially involved fields. Nevertheless, two new nodular lesions were detected in the left lower lobe. Biopsy revealed granulomas, and PCR was positive for M. tuberculosis. Our patient received treatment with the combination of isoniazid and rifampin (12 months, pyrazinamide (the first 2 months, and maintenance chemotherapy for her ALCL for one year simultaneously. Four years later, she is disease free for both mycobacterial infection and lymphoma. We are reporting this successful management of mycobacterial infection in a patient with ALCL despite intensive chemotherapy that the patient received at the same time.

    Every year, a lot of Tuberculosis (TB) patients undergo Directly Observed Treatment Short-course (DOTS) in Salem city, one of the high TB districts in South India. Mobile phone usage among these patients and health workers is common. Mobile phone communication has a great potential in TB treatment. To analyze the mobile phone usage and its effectiveness in TB DOTS treatment. A cross-sectional survey with 150 TB patients was followed by a focus group discussion with treatment supervisors, DOTS providers, and health workers. Majority of patients use mobile phones to make calls to health workers to clarify their doubts on side effects, food, and symptoms of the disease. TB treatment supervisors effectively use mobile phones to counsel patients to adhere to the treatment regimen. Patients see mobile phones as a useful communication tool in TB treatment though they prefer direct interpersonal communication with health workers. Though the mobile ownership is 68% among the TB patients, many of them are not able to send text messages or read messages in English. Mobile phone possession and usage is high among the patients. Patients need to be trained to use mobile phone features such as alarm, voice mail, and interactive voice response. Incentives like free talk time and short message service (SMS) will encourage patients to communicate frequently with health workers, thereby, increasing the chances of better adherence to DOTS. SMS could be made available in the regional languages.

    The aim of the study was to explore the views of tuberculosis (TB) physicians on treatment of latent TB infection (LTBI), focusing on decision making and communication in clinical practice. 20 Australian TB physicians participated in a semistructured interview in person or over the telephone. Interviews were recorded, transcribed and analysed thematically. The study identified challenges that physicians face when discussing treatment for LTBI with patients. These included difficulties explaining the concept of latency (in particular to patients from culturally and linguistically diverse backgrounds) and providing guidance to patients while still framing treatment decisions as a choice. Tailored estimates of the risk of developing TB and the risk of developing an adverse effect from LTBI treatment were considered the most important information for decision making and discussion with patients. Physicians acknowledged that there is a significant amount of unwarranted treatment variation, which they attributed to the lack of evidence about the risk-benefit balance of LTBI treatment in certain scenarios and guidelines that refer to the need for case-by-case decision making in many instances. In order to successfully implement LTBI treatment at a clinical level, consideration should be given to research on how to best address communication challenges arising in clinical encounters.

    ABSTRACT In a Mycobacterium smegmatis mutant library screen, transposon mutants with insertions in fhaA, dprE2, rpsT, and parA displayed hypersusceptibility to antibiotics, including the β-lactams meropenem, ampicillin, amoxicillin, and cefotaxime. Sub-MIC levels of octoclothepin, a psychotic drug inhibiting ParA, phenocopied the parA insertion and enhanced the bactericidal activity of meropenem against Mycobacterium tuberculosis in combination with clavulanate. Our study identifies novel factors associated with antibiotic resistance, with implications in repurposing β-lactams for tuberculosis treatment. PMID:28438925

    Full Text Available Abstract Background Papua New Guinea (PNG is a diverse and culturally-rich country with severe infrastructural and health problems. Tuberculosis (TB is widespread, and the number of cases with drug resistance is rising. Treatment adherence is known to be important for both effective treatment and limiting the emergence of drug resistance. The aim of this study was to construct a matrix of the factors that act as facilitators or barriers to TB treatment adherence in a remote region of PNG. Methods The study was based in the Balimo region of the Western Province. People known to have undergone TB treatment, as well as staff involved in managing people with TB, were asked to participate in an in-depth interview about their experiences. Purposive sampling was used to identify a diverse range of participants, from different geographic locations, social backgrounds, and with successful and unsuccessful treatment outcomes. The interview data was analysed based on grounded theory methodology. Results The study identified a range of factors that influence TB treatment adherence, with these being classified as personal, systems, and sociocultural. These factors are presented along with suggested recommendations for adaptations to DOTS-based treatment in this region. Barriers included the challenges associated with travel to treatment sites, and the difficulties of undertaking treatment alongside the daily need to maintain subsistence food production. However, facilitators were also identified, including the positive influence of religious beliefs, and high confidence in the ability of DOTS-based treatment to cure TB. Conclusions Documenting the wide range of factors that influence treatment adherence in a severely affected remote population will assist in improving TB control. These results provide impetus for further community-based efforts aimed at improving access to TB diagnosis and treatment, and maintaining successful treatment outcomes in the face

    Full Text Available Abstract Background Tuberculosis remains an important disease which mainly affects the majority of vulnerable individuals in society, who are subjected to poor living conditions and difficulties to access the services of public health. Under these circumstances, the present study aims to understand patients’ perception in relation to the influence of individual and social vulnerabilities on the adherence to tuberculosis treatment. Methods A qualitative descriptive cross sectional study was conducted in one large municipality at the state of Paraíba, Northeast of Brazil. The study subjects, who were residents of the study site, covered all tuberculosis cases diagnosed between March and June 2015. The sample was defined by the criteria of response saturation. All interviews were audio recorded, and data analysis was developed through the hermeneutic dialectic method and the theory of Generative Route Sense.

Results A total of 13 individuals were interviewed and the responses were identified into two analytical categories: the difficulties they had and the enabling factors they could mention during their tuberculosis treatment. Patients brought up social exclusion as an obstacle to treatment adherence, which, along with stigmatization, weakened their link with family members and health professionals. Moreover, economic precariousness was a major hindrance to the maintenance of a proper diet and transportation access to health centers. However, social support and directly observed treatment helped to break down barriers of prejudice and to promote individual and family empowerment. Finally, patients also reported that their will to live and faith gave them the strength to continue with the treatment. Conclusions According to patients in this study, social support and the strengthening of links with family members and health professionals may reduce

    Tuberculosis remains an important disease which mainly affects the majority of vulnerable individuals in society, who are subjected to poor living conditions and difficulties to access the services of public health. Under these circumstances, the present study aims to understand patients' perception in relation to the influence of individual and social vulnerabilities on the adherence to tuberculosis treatment. A qualitative descriptive cross sectional study was conducted in one large municipality at the state of Paraíba, Northeast of Brazil. The study subjects, who were residents of the study site, covered all tuberculosis cases diagnosed between March and June 2015. The sample was defined by the criteria of response saturation. All interviews were audio recorded, and data analysis was developed through the hermeneutic dialectic method and the theory of Generative Route Sense. The project was approved by the Research Ethics Committee of the University of São Paulo (USP). A total of 13 individuals were interviewed and the responses were identified into two analytical categories: the difficulties they had and the enabling factors they could mention during their tuberculosis treatment. Patients brought up social exclusion as an obstacle to treatment adherence, which, along with stigmatization, weakened their link with family members and health professionals.

    Full Text Available Objective of our study was to increase the effectiveness of surgical treatment of bilateral destructive pulmonary tuberculosis complicated by pleural empyema by using VTS-technologies. The study was done in Dnepropetrovsk regional clinical therapeutic and prophylactic association "Phthisiology" in the period from 2008 to 2013. A retrospective analysis of 43 cases of bilateral destructive pulmonary tuberculosis complicated by pleural empyema on one side and dissemination focus or limited destructive process on contralateral side has been performed. Selected cases were divided into 2 groups: main (eighteen cases where the following procedures were done: performed transsternal occlusion of the main bronchus, sanation of empyema cavity using videothoracosopy, in 30-45 days followed by pleuropneumectomy with usage of minithoracothomy and control (nineteen cases who had undergone drainage of the empyema cavity, sanation, in 45-60 days followed by pleuropmeumectomy with usage of anterolateral access. The distribution of main and control groups for analyzed parameters was representative. Sanation of pleural cavity with videothoracosopy usage compared with Bulau’s drainage provides better antibacterial effect, effective sanitation of the pleural cavity as evidenced by following changes: significant decrease in the number of microbial cells; normalization of total white blood cells count and rod-shaped granulocytes in the peripheral blood 10 days after treatment; normalization of leukocyte intoxication index. The use of minimally invasive surgical treatment allowed to reduce intraoperative complications by 2 times, amount of intraoperative blood loss and hemotrasfusions by 1.5 times, postoperative mortality by 2.5 times. Pleural cavity sanation with videothoracoscopy usage with following pneumoectomy leads to reduce in the incidence and severity of postoperative complications. The most promising is stage-by-stage surgical approach with consecutive use

    International and Spanish guidelines recommend a 4-drug regimen in the intensive treatment of tuberculosis (TB). The aim of our study was to determine if these recommendations are followed in Spain, and the factors associated with the use of 3 drugs (standard regimen without ethambutol). Observational, multicenter, retrospective analysis of data from patients diagnosed with TB in practically all Spanish Autonomous Communities between 2007 and 2102. Factors associated with the use of 3 drugs were analyzed using logistic regression, and odds ratios (OR) and corresponding 95% confidence intervals (CI) were calculated. A total of 3,189 patients were included, 1,413 (44.3%) of whom received 3 drugs. The percentage of 3-drug users among patients with positive sputum smear was 41.2%; among patients with resistance to at least 1 drug, 36.1%; among HIV-infected patients, 31.4%; and among immigrants, 24.8%. Factors associated with the use of 3 drugs were: female sex (OR=1.18; CI: 1.00-1.39); native Spanish (OR=3.09; CI: 2.58-3.70); retired (OR=1.42; CI: 1.14-1.77); homeless (OR=3.10; CI: 1.52-6.43); living alone (OR=1.62; CI: 1.11-2.36); living in a family (OR=1.97; CI: 1.48-2.65); seen by specialists in the region (OR=1.37; CI: 1.10;1.70); no HIV infection (OR=1.63; CI: 1.09-2.48); and negative sputum smear with positive culture (OR=1.59; CI: 1.25-2.02). A large proportion of TB patients receive intensive treatment with 3 drugs. TB treatment recommendations should be followed, both in routine clinical practice and by the National Plan for Prevention and Control of Tuberculosis in Spain. Copyright © 2015 SEPAR.

    Full Text Available BACKGROUND: Excessive time between diagnosis and initiation of tuberculosis (TB treatment contributes to ongoing TB transmission and should be minimized. In India, Revised National TB Control Programme (RNTCP focuses on indicator start of treatment within 7 days of diagnosis for patients with sputum smear-positive PTB for monitoring DOTS implementation. OBJECTIVES: To determine length of time between diagnosis and initiation of treatment and factors associated with delays of more than 7 days in smear-positive pulmonary TB. METHODS: Using existing programme records such as the TB Register, treatment cards, and the laboratory register, we conducted a retrospective cohort study of all patients with smear-positive pulmonary TB registered from July-September 2010 in two districts in India. A random sample of patients with pulmonary TB who experienced treatment delay of more than 7 days was interviewed using structured questionnaire. RESULTS: 2027 of 3411 patients registered with pulmonary TB were smear-positive. 711(35% patients had >7 days between diagnosis and treatment and 262(13% had delays >15 days. Mean duration between TB diagnosis and treatment initiation was 8 days (range = 0-128 days. Odds of treatment delay >7 days was 1.8 times more likely among those who had been previously treated (95% confidence interval [CI] 1.5-2.3 and 1.6 (95% CI 1.3-1.8 times more likely among those diagnosed in health facilities without microscopy centers. The main factors associated with a delay >7 days were: patient reluctance to start a re-treatment regimen, patients seeking second opinions, delay in transportation of drugs to the DOT centers and delay in initial home visits. To conclude, treatment delay >7 days was associated with a number of factors that included history of previous treatment and absence of TB diagnostic services in the local health facility. Decentralized diagnostic facilities and improved referral procedures may reduce such treatment

    Default from tuberculosis (TB) treatment could exacerbate the disease and result in the emergence of drug resistance. This study identified the risk factors for default from TB treatment in Korea. This single-center case-control study analyzed 46 default cases and 100 controls. Default was defined as interrupting treatment for 2 or more consecutive months. The reasons for default were mainly incorrect perception or information about TB (41.3%) and experience of adverse events due to TB drugs (41.3%). In univariate analysis, low income (defaulter (15.2% vs. 2.0%, P = 0.005), and combined extrapulmonary TB (54.3% vs. 34.0%, P = 0.020) were significant risk factors for default. In multivariate analysis, the absence of TB stigma (adjusted odd ratio [aOR]: 46.299, 95% confidence interval [CI]: 8.078-265.365, P defaulters (aOR: 33.226, 95% CI: 2.658-415.309, P = 0.007), and low income (aOR: 5.246, 95% CI: 1.249-22.029, P = 0.024) were independent predictors of default from TB treatment. In conclusion, patients with absence of disease stigma, treated by a non-pulmonologist, who were former defaulters, and with low income should be carefully monitored during TB treatment in Korea to avoid treatment default.

    To determine the frequency and characteristics of patients with unsuccessful tuberculosis (TB) treatment. Random selection of TB case registers among all treatment units in Cambodia, two provinces in China, and Viet Nam. The data of two calendar years were analyzed to assess unsuccessful outcomes and their time of occurrence. Among the 33 309 TB patients, treatment was unsuccessful in respectively 10.1%, 3.0% and 9.1% of patients in Cambodia, China and Viet Nam. The risk of death was highest in Cambodia, higher among males than females, increased with age, and was more common among retreatment cases than new cases, and among patients with a high than a low sputum smear microscopy grade. Half of all deaths occurred in the first 2 months in Cambodia and within 11 weeks in China and Viet Nam. Median time to default was 3 months in Cambodia and Viet Nam, and about 2 months in China. Treatment was highly successful in the three study countries, with a low proportion of death and default. As the majority of defaulting occurs at the beginning of treatment, all countries should critically review their current policy of treatment support in this period.

    Full Text Available Anti-tuberculosis drug induced liver injury (ATLI is emerging as a significant threat to tuberculosis control in China, though limited data is available about the burden of ATLI at population level. This study aimed to estimate the incidence of ATLI, to better understand its clinical features, and to evaluate its impact on anti-tuberculosis (TB treatment in China.In a population-based prospective study, we monitored 4,304 TB patients receiving directly observed treatment strategy (DOTS treatment, and found that 106 patients developed ATLI with a cumulative incidence of 2.55% (95% Confidence Interval [CI], 2.04%-3.06%. Nausea, vomiting and anorexia were the top three most frequently observed symptoms. There were 35 (33.02% ATLI patients with no symptoms, including 8 with severe hepatotoxicity. Regarding the prognosis of ATLI, 84 cases (79.25% recovered, 18 (16.98% improved, 2 (1.89% failed to respond to the treatment with continued elevation of serum alanine aminotransferase, and 2 (1.89% died as result of ATLI. Of all the ATLI cases, 74 (69.81% cases changed their anti-TB treatment, including 4 (3.77% cases with medication administration change, 21 (19.81% cases with drugs replacement, 54 (50.94% cases with therapy interruption, and 12 (11.32% cases who discontinued therapy. In terms of treatment outcomes, 53 (51.46% cases had TB cured in time, 48 (46.60% cases had therapy prolonged, and 2 (1.94% cases died. Compared with non-ATLI patients, ATLI patients had a 9.25-fold (95%CI, 5.69-15.05 risk of unsuccessful anti-TB treatment outcomes and a 2.11-fold (95%CI, 1.23-3.60 risk of prolonged intensive treatment phase.ATLI could considerably impact the outcomes of anti-TB treatment. Given the incidence of ATLI and the size of TB population in China, the negative impact is substantial. Therefore, more research and efforts are warranted in order to enhance the diagnosis and the prevention of ATLI.

    Recently, a short-course treatment using 60 daily doses of rifampin and pyrazinamide was recommended for latent tuberculosis (TB) infection (LTBI). To determine the acceptability, tolerability, and completion of treatment. Observational cohort study. Five county jails and TB outreach clinics for homeless populations in three cities. Study staff enrolled 1,211 patients (844 inmates and 367 homeless persons). Sites used 60 daily doses of rifampin and pyrazinamide, an approved treatment regimen for LTBI. Types and frequency of drug-related adverse events and outcomes of treatment. Prior to treatment, 25 of 1,178 patients (2.1%) had a serum aminotransferase measurement at least 2.5 times the upper limit of normal. Patients who reported excess alcohol use in the past 12 months were more likely than other patients to have an elevated pretreatment serum aminotransferase level (odds ratio, 2.1; 95% confidence interval, 1.1 to 6.1; p = 0.03). Treatment was stopped in 66 of 162 patients (13.4%) who had a drug-related adverse event. Among 715 patients who had serum aminotransferase measured during treatment, 43 patients (6.0%) had an elevation > 5 times the upper limits of normal, including one patient who died of liver failure attributed to treatment. In multivariate analyses, increasing age, an abnormal baseline aspartate aminotransferase level, and unemployment within the past 24 months were independent risk factors for hepatotoxicity. Completion rates were similar in jail inmates (47.5%) and homeless persons (43.6%). This study detected the first treatment-associated fatality with the rifampin and pyrazinamide regimen, prompting surveillance that detected unacceptable levels of hepatotoxicity and retraction of recommendations for its routine use. Completion rates for LTBI treatment using a short-course regimen exceeds historical rates using isoniazid. Efforts to identify an effective short-course treatment for LTBI should be given a high priority.

    Every year, over 1 million people develop isoniazid (INH) resistant tuberculosis (TB). Yet, the optimal treatment regimen remains unclear. Given increasing prevalence, the clinical efficacy of regimens used by physicians is of interest. This study aims to examine treatment outcomes of INH resistant TB patients, treated under programmatic conditions in British Columbia, Canada. Medical charts were retrospectively reviewed for cases of culture-confirmed INH mono-resistant TB reported to the BC Centre for Disease Control (BCCDC) from 2002 to 2014. Treatment regimens, patient and strain characteristics, and clinical outcomes were analysed. One hundred sixty five cases of INH mono-resistant TB were included in analysis and over 30 different treatment regimens were prescribed. Median treatment duration was 10.5 months (IQR 9-12 months) and treatment was extended beyond 12 months for 26 patients (15.8%). Fifty six patients (22.6%) experienced an adverse event that resulted in a drug regimen modification. Overall, 140 patients (84.8%) had a successful treatment outcome while 12 (7.2%) had an unsuccessful treatment outcome of failure (n = 2; 1.2%), relapse (n = 4; 2.4%) or all cause mortality (n = 6; 3.6%). Our treatment outcomes, while consistent with findings reported from other studies in high resource settings, raise concerns about current recommendations for INH resistant TB treatment. Only a small proportion of patients completed the recommended treatment regimens. High quality studies to confirm the effectiveness of standardized regimens are urgently needed, with special consideration given to trials utilizing fluoroquinolones.

    Full Text Available Background: Psychological distress is the major comorbidity among tuberculosis (TB patients. However, its magnitude, associated factors, and effect on treatment outcome have not been adequately studied in low-income countries. Objective: This study aimed to determine the magnitude of psychological distress and its effect on treatment outcome among TB patients on treatment. Design: A follow-up study was conducted in Addis Ababa, Ethiopia, from May to December 2014. Patients (N=330 diagnosed with all types of TB who had been on treatment for 1–2 months were enrolled consecutively from 15 randomly selected health centers and one TB specialized hospital. Data on sociodemographic variables and economic status were collected using a structured questionnaire. The presence of psychological distress was assessed at baseline (within 1–2 months after treatment initiation and end point (6 months after treatment initiation using the 10-item Kessler (K-10 scale. Alcohol use and tobacco smoking history were assessed using WHO Alcohol Use Disorder Identification Test and Australian Smoking Assessment Checklist, respectively. The current WHO TB treatment outcome definition was used to differentiate the end result of each patient at completion of the treatment. Results: The overall psychological distress was 67.6% at 1–2 months and 48.5% at 6 months after treatment initiation. Multiple logistic regression analysis revealed that past TB treatment history [adjusted odds ratio (AOR: 3.76; 95% confidence interval (CI: 1.67–8.45], being on anti-TB and anti-HIV treatments (AOR: 5.35; 95% CI: 1.83–15.65, being unmarried (AOR: 4.29; 95% CI: 2.45–7.53, having alcohol use disorder (AOR: 2.95; 95% CI: 1.25–6.99, and having low economic status (AOR: 4.41; 95% CI: 2.44–7.97 were significantly associated with psychological distress at baseline. However, at 6 months after treatment initiation, only being a multidrug-resistant tuberculosis (MDR-TB patient (AOR: 3

    Vitamin D deficiency (VDD) is a common condition among several populations in the world. VDD is associated with higher incidence of immune system disorders and faster progression of some infectious diseases. Vitamin D is known to be of physiological importance, it is considered an essential micronutrient for the bone health and plays a beneficial role in the prevention and/or treatment of a number of chronic diseases. Vitamin D has a complex action on the immune system. Evidence that vitamin D protects against tuberculosis has been supported by in vitro, epidemiological and some preliminary clinical studies. Vitamin D has a potential effect on HIV (human immunodeficiency virus) and plays a crucial role in the defence against respiratory infections. Vitamin D supplementation could be a low-cost, practical method to protect groups of people with high incidence of those diseases. Public health education should stress the need for adequate dietary intake of vitamin D in those vulnerable groups.

    Completing treatment for multidrug-resistant (MDR) tuberculosis (TB) may be more challenging than completing first-line TB therapy, especially in resource-poor settings. The objectives of this study were to (1) identify risk factors for default from MDR TB therapy (defined as prolonged treatment interruption), (2) quantify mortality among patients who default from treatment, and (3) identify risk factors for death after default from treatment. We performed a retrospective chart review to identify risk factors for default from MDR TB therapy and conducted home visits to assess mortality among patients who defaulted from such therapy. Sixty-seven (10.0%) of 671 patients defaulted from MDR TB therapy. The median time to treatment default was 438 days (interquartile range, 152-710 days), and 27 (40.3%) of the 67 patients who defaulted from treatment had culture-positive sputum at the time of default. Substance use (hazard ratio, 2.96; 95% confidence interval, 1.56-5.62; P = .001), substandard housing conditions (hazard ratio, 1.83; 95% confidence interval, 1.07-3.11; P = .03), later year of enrollment (hazard ratio, 1.62, 95% confidence interval, 1.09-2.41; P = .02), and health district (P = .02) predicted default from therapy in a multivariable analysis. Severe adverse events did not predict default from therapy. Forty-seven (70.1%) of 67 patients who defaulted from therapy were successfully traced; of these, 25 (53.2%) had died. Poor bacteriologic response, default, low education level, and diagnosis with a psychiatric disorder significantly predicted death after default in a multivariable analysis. The proportion of patients who defaulted from MDR TB treatment was relatively low. The large proportion of patients who had culture-positive sputum at the time of treatment default underscores the public health importance of minimizing treatment default. Prognosis for patients who defaulted from therapy was poor. Interventions aimed at preventing treatment default may

    Full Text Available Abstract Background Delayed diagnosis and treatment of tuberculosis (TB results in severe disease and a higher mortality. It also leads to an increased period of infectivity in the community. The objective of this study was to determine the length of delays, and analyze the factors affecting the delay from onset of symptoms of pulmonary tuberculosis (PTB until the commencement of treatment. Methods In randomly selected TB management units (TBMUs, i.e. government health institutions which have diagnosing and treatment facilities for TB in Amhara Region, we conducted a cross sectional study from September 1-December 31/2003. Delay was analyzed from two perspectives, 1. Period between onset of TB symptoms to first visit to any health provider (health seeking period, and from the first health provider visit to initiation of treatment (health providers' delay, and 2. Period between onset of TB symptoms to first visit to a medical provider (patients' delay, and from this visit to commencement of anti-TB treatment (health systems' delay. Patients were interviewed on the same date of diagnosis using a semi-structured questionnaire. Logistics regression analysis was applied to analyze the risk factors of delays. Results A total of 384 new smear positive PTB patients participated in the study. The median total delay was 80 days. The median health-seeking period and health providers' delays were 15 and 61 days, respectively. Conversely, the median patients' and health systems' delays were 30 and 21 days, respectively. Taking medical providers as a reference point, we found that forty eight percent of the subjects delayed for more than one month. Patients' delays were strongly associated with first visit to non-formal health providers and self treatment (P Conclusion Delay in the diagnosis and treatment of PTB is unacceptably high in Amhara region. Health providers' and health systems' delays represent the major portion of the total delay. Accessing a

    While active tuberculosis (TB) is a treatable disease, many complex factors prevent its global elimination. Part of the difficulty in developing optimal therapies is the large design space of antibiotic doses, regimens and combinations. Computational models that capture the spatial and temporal dynamics of antibiotics at the site of infection can aid in reducing the design space of costly and time-consuming animal pre-clinical and human clinical trials. The site of infection in TB is the granuloma, a collection of immune cells and bacteria that form in the lung, and new data suggest that penetration of drugs throughout granulomas is problematic. Here we integrate our computational model of granuloma formation and function with models for plasma pharmacokinetics, lung tissue pharmacokinetics and pharmacodynamics for two first line anti-TB antibiotics. The integrated model is calibrated to animal data. We make four predictions. First, antibiotics are frequently below effective concentrations inside granulomas, leading to bacterial growth between doses and contributing to the long treatment periods required for TB. Second, antibiotic concentration gradients form within granulomas, with lower concentrations toward their centers. Third, during antibiotic treatment, bacterial subpopulations are similar for INH and RIF treatment: mostly intracellular with extracellular bacteria located in areas non-permissive for replication (hypoxic areas), presenting a slowly increasing target population over time. Finally, we find that on an individual granuloma basis, pre-treatment infection severity (including bacterial burden, host cell activation and host cell death) is predictive of treatment outcome.

    To estimate the provider costs of managing adverse drug reactions (ADRs) to standard long-course treatment for multidrug- and rifampicin-resistant tuberculosis (MDR/RR-TB) according to South African guidelines. We parameterised a published Markov health state model for MDR/RR-TB with guidelines-based, bottom-up public-sector provider costing of ADR management. Frequency of ADR occurrence was extracted from the literature. Costs were estimated over 10 years, discounted 3% annually and tested using probabilistic sensitivity analysis. On average, guidelines-based costing of moderate ADRs weighted by the frequency of occurrence was US$135.76 (standard deviation [SD] US$17.18) and the cost of serious ADRs was US$521.29 (SD US$55.99). We estimated that the incremental costs of ADR management were US$380.17 annually per patient initiating MDR/RR-TB treatment. The incremental costs of ADR management for the public health sector in South Africa was US$4.76 million, 8.3% of the estimated cohort costs of MDR/RR-TB treatment ($57.55 million) for the 2015 cohort of 12 527 patients. Management of multiple ADRs and serious ADRs, which are common during the first 6 months of standard, long-course MDR/RR-TB treatment, substantially increases provider treatment costs. These results need to be taken into account when comparing regimen costs, and highlight the urgent need to identify drug regimens with improved safety profiles.

    Debate persists about monitoring method (culture or smear) and interval (monthly or less frequently) during treatment for multidrug-resistant tuberculosis (MDR-TB). We analysed existing data and estimated the effect of monitoring strategies on timing of failure detection. We identified studies reporting microbiological response to MDR-TB treatment and solicited individual patient data from authors. Frailty survival models were used to estimate pooled relative risk of failure detection in the last 12 months of treatment; hazard of failure using monthly culture was the reference. Data were obtained for 5410 patients across 12 observational studies. During the last 12 months of treatment, failure detection occurred in a median of 3 months by monthly culture; failure detection was delayed by 2, 7, and 9 months relying on bimonthly culture, monthly smear and bimonthly smear, respectively. Risk (95% CI) of failure detection delay resulting from monthly smear relative to culture is 0.38 (0.34–0.42) for all patients and 0.33 (0.25–0.42) for HIV-co-infected patients. Failure detection is delayed by reducing the sensitivity and frequency of the monitoring method. Monthly monitoring of sputum cultures from patients receiving MDR-TB treatment is recommended. Expanded laboratory capacity is needed for high-quality culture, and for smear microscopy and rapid molecular tests. PMID:27587552

    Defaulting from anti-tuberculosis treatment hinders tuberculosis (TB) control. To identify potential defaulters. We conducted a cohort study in newly diagnosed Indonesian TB patients. We administered a questionnaire, prospectively identified defaulters (discontinued treatment ≥ 2 weeks) and assessed risk factors using Cox's regression. Of 249 patients, 39 (16%) defaulted, 61% in the first 2 months. Default was associated with liver disease (HR 3.40, 95%CI 1.02-11.78), chest pain (HR 2.25, 95%CI 1.06-4.77), night sweats (HR 1.98, 95%CI 1.03-3.79), characteristics of the head of the household (self-employed, HR 2.47, 95%CI 1.15-5.34; patient's mother, HR 7.72, 95%CI 1.66-35.88), household wealth (HR 4.24, 95%CI 1.12-16.09), walking to clinic (HR 4.53, 95%CI 1.39-14.71), being unaccompanied at diagnosis (HR 30.49, 95%CI 7.55-123.07) or when collecting medication (HR 3.34, 95%CI 1.24-8.98) and low level of satisfaction with the clinic (HR 3.85, 95%CI 1.17-12.62) or doctors (HR 2.45, 95%CI 1.18-5.10). Health insurance (HR 0.24, 95%CI 0.07-0.74) and paying for diagnosis (HR 0.14, 95%CI 0.04-0.48) were protective. Defaulting is common and occurs early. Interventions that improve clinic services, strengthen patient support and increase insurance coverage may reduce default in Indonesia.

    Vitamin D has been shown to be involved in the host immune response toward Mycobacterium tuberculosis. To test whether vitamin D supplementation of patients with tuberculosis (TB) improved clinical outcome and reduced mortality. We conducted a randomized, double-blind, placebo-controlled trial in TB clinics at a demographic surveillance site in Guinea-Bissau. We included 365 adult patients with TB starting antituberculosis treatment; 281 completed the 12-month follow-up. The intervention was 100,000 IU of cholecalciferol or placebo at inclusion and again 5 and 8 months after the start of treatment. The primary outcome was reduction in a clinical severity score (TBscore) for all patients with pulmonary TB. The secondary outcome was 12-month mortality. No serious adverse effects were reported; mild hypercalcemia was rare and present in both arms. Reduction in TBscore and sputum smear conversion rates did not differ among patients treated with vitamin D or placebo. Overall mortality was 15% (54 of 365) at 1 year of follow-up and similar in both arms (30 of 187 for vitamin D treated and 24 of 178 for placebo; relative risk, 1.19 [0.58-1.95]). HIV infection was seen in 36% (131 of 359): 21% (76 of 359) HIV-1, 10% (36 of 359) HIV-2, and 5% (19 of 357) HIV-1+2. Vitamin D does not improve clinical outcome among patients with TB and the trial showed no overall effect on mortality in patients with TB; it is possible that the dose used was insufficient. Clinical trial registered with www.controlled-trials.com/isrctn (ISRCTN35212132).

    With the colliding global epidemics of diabetes mellitus (DM) and tuberculosis (TB), we studied the effects of DM on the presentation of TB and its response to treatment. Consecutive TB patients from 2006 to 2010 in a territory-wide treatment programme offering 9-month extended treatment for TB patients with DM were examined and followed up prospectively to assess their treatment response. Successful treatment completers were tracked through the TB registry and death registry for relapse, death or till 31 December 2014, whichever was the earliest. DM was independently associated with more chest symptoms (adjusted OR (AOR): 1.13) and systemic symptoms (AOR: 1.30) but less with other site-specific symptoms (AOR: 0.58) at TB presentation. There was more frequent pulmonary involvement (AOR: 1.69), with more extensive lung lesion (AOR: 1.25), lung cavity (AOR: 2.00) and positive sputum smear (AOR: 1.83) and culture (AOR: 1.38), but no difference in the proportion of retreatment cases or isoniazid and/or rifampicin resistance. After treatment initiation, there was higher overall incidence (AOR: 1.38) of adverse effects (mainly gastrointestinal symptoms, renal impairment and peripheral neuropathy but less fever and skin hypersensitivity reactions), more smear non-conversion (AOR: 1.59) and culture non-conversion (AOR: 1.40) at 2 months, and lower combined cure/treatment completion rate at 12 months (AOR: 0.79), but no difference in the relapse rate after having successfully completed treatment. DM adversely affected the clinical presentation and treatment response of TB, but there was no difference in the drug resistance and relapse rates. © 2017 Asian Pacific Society of Respirology.

    To measure the expression levels of sputum and serum microRNA-144 (miR-144) before and after the treatment of patients with tuberculosis (TB). Details of the cases of a total of 124 TB patients were collected at Qilu Hospital of Shandong University between April 2014 and April 2015. Fifty-three of these patients had sputum positive for bacteria and a cavity on imaging (group A), 20 patients had sputum negative for bacteria and a cavity on imaging (group B), and 51 patients had sputum negative for bacteria and no cavity on imaging (group C). One hundred seventeen healthy people who attended the hospital for a physical examination were recruited as controls. Quantitative real-time PCR (qRT-PCR) was used to measure the levels of sputum and serum miR-144 before anti-TB treatment and at 1 month after treatment. Before treatment, sputum and serum miR-144 expression levels in the TB patients were both higher than those of the controls (both p<0.05). After treatment, sputum and serum miR-144 levels in the TB patients were significantly lower than those measured before treatment (both p<0.05). The levels of sputum and serum miR-144 in the improved TB patients decreased significantly after treatment compared to those measured before treatment (both p<0.001). Significant differences were found in sputum and serum miR-144 levels in the TB patients, with or without improvement, compared with the healthy controls (all p<0.05). Sputum and serum miR-144 levels were significantly upregulated in the TB patients, but were found to decrease significantly after anti-TB treatment. Copyright © 2016 The Authors.

    Treatment of latent tuberculosis infection (LTBI) is an important component of tuberculosis (TB) control, and this study updates a previous network meta-analysis of the best LTBI treatment options to inform public health action and programmatic management of LTBI. To evaluate the comparative efficacy and harms of LTBI treatment regimens aimed at preventing active TB among adults and children. PubMed, Embase, and Web of Science from indexing to 8 May 2017; clinical trial registries; and conference abstracts. No language restrictions were applied. Randomized controlled trials that evaluated human LTBI treatments and recorded at least 1 of 2 prespecified end points (hepatotoxicity and prevention of active TB). 2 investigators independently extracted data from eligible studies and assessed study quality according to a standard protocol. The network meta-analysis of 8 new and 53 previously included studies showed that isoniazid regimens of 6 months (odds ratio [OR], 0.65 [95% credible interval {CrI}, 0.50 to 0.83]) or 12 to 72 months (OR, 0.50 [CrI, 0.41 to 0.62]), rifampicin-only regimens (OR, 0.41 [CrI, 0.19 to 0.85]), rifampicin-isoniazid regimens of 3 to 4 months (OR, 0.53 [CrI, 0.36 to 0.78]), rifampicin-isoniazid-pyrazinamide regimens (OR, 0.35 [CrI, 0.19 to 0.61]), and rifampicin-pyrazinamide regimens (OR, 0.53 [CrI, 0.33 to 0.84]) were efficacious compared with placebo. Evidence existed for efficacy of weekly rifapentine-isoniazid regimens compared with no treatment (OR, 0.36 [CrI, 0.18 to 0.73]). No conclusive evidence showed that HIV status altered treatment efficacy. Evidence was sparse for many comparisons and hepatotoxicity outcomes, and risk of bias was high or unknown for many studies. Evidence exists for the efficacy and safety of 6-month isoniazid monotherapy, rifampicin monotherapy, and combination therapies with 3 to 4 months of isoniazid and rifampicin.

    Background Patient compliance is a key factor in treatment success. Satisfied patients are more likely to utilize health services, comply with medical treatment, and continue with the health care providers. Yet, the national tuberculosis control program failed to address some of these aspects in order to achieve the national targets. Hence, this study attempted to investigate patient satisfaction and adherence to tuberculosis treatment in Sidama zone of south Ethiopia. Methods A facility based cross sectional study was conducted using quantitative method of data collection from March to April 2011. A sample of 531 respondents on anti TB treatment from 11 health centers and 1 hospital were included in the study. The sample size to each facility was allocated using probability proportional to size allocation, and study participants for the interview were selected by systematic random sampling. A Pre tested, interviewer administered questionnaire was used to collect the data. Collected data was edited, coded and entered to Epi data version 3.1 and exported to SPSS version 16. Confirmatory factor analysis was done to identify factors that explain most of the variance observed in most of the manifested variables. Bivariate and Multivariate analysis were computed to analyze the data. Result The study revealed 90% of the study participants were satisfied with TB treatment service. However, 26% of respondents had poor adherence to their TB treatment. Patient perceived on professional care, time spent with health care provider, accessibility, technical competency, convenience (cleanliness) and consultation and relational empathy were independent predictors of overall patient satisfaction (P patient satisfaction (Beta = 0.262). In multivariate analysis occupational status, area of residence, perceived time spent with health care provider, perceived accessibility, perceived waiting time, perceived professional care and over all patient satisfaction were significantly

    Full Text Available Introduction. Pulmonary tuberculosis remains prominent as one of public health problems in the world. Patients’ non-compliance to treatment is a significant contributor to drug resistance. This study aimed to develop and to test the efficacy of a nursing care model to prevent non-compliance. Method This study consisted of two phases: phase one, model development, used a descriptive analytic, and phase two, model testing, employed a quasi-experimental design. Participants, comprised both patients and nurses at two health care centres in Surabaya, were recruited by consecutive sampling. Data were collected by interview, self-administered-questionnaires, check-list and focused group discussion. Data analyses were performed using both partial least squares and Wilcoxon signed rank test. Results. The model was statistically effective to improve nearly all aspects of patients’ compliance to TB treatment (knowledge, discipline in taking medications regularity of controls, and abilities to monitor the results of treatment with p < 0.05, except for abilities to cope with drug adverse effects (p = 1.000. This is possible because seldom do patients aware of the medication side effects, so their experiences were probably limited. Conclusion. This study concludes that the KM nursing care model was proven effective to improve patients’ adherence to treatment. Future study is suggested to evaluate the impact of the KM nursing care model in bigger population.

    To estimate the cost of providing tuberculosis (TB) diagnosis and treatment packages at different levels of health facilities in Viet Nam. This was a retrospective costing study from the providers' perspective using a standard costing approach. We included typical services for TB diagnosis and treatment based on standard protocols. The least expensive TB service was the 6-month isoniazid preventive therapy regimen for latent tuberculous infection provided by district health centres (US$7.20-14.30, accounting for 0.3-0.7% of Viet Nam's per capita gross domestic product [GDP] of US$2052.30 in 2014). The cost of diagnosing and treating a patient with drug-susceptible TB (the most common type of TB) ranged between US$51.20 and US$180.70, and represented 2.5-8.8% of Viet Nam's per capita GDP in 2014. The most expensive TB service was the diagnosis and treatment of a multidrug-resistant TB case (US$1568.20-2391.20), accounting for 76.4-116.5% of Viet Nam's per capita GDP in 2014). The cost of TB diagnosis and treatment services in Viet Nam varied according to level of health facility, type of TB, different costing options, and different staff cost scenarios.

    Full Text Available Abstract Background Detection of lipoarabinomannan (LAM, a Mycobacterium tuberculosis (Mtb cell wall antigen, is a potentially attractive diagnostic. However, the LAM-ELISA assay has demonstrated variable sensitivity in diagnosing TB in diverse clinical populations. We therefore explored pathogen and host factors potentially impacting LAM detection. Methods LAM-ELISA assay testing, sputum smear and culture status, HIV status, CD4 cell count, proteinuria and TB outcomes were prospectively determined in adults diagnosed with TB and commencing TB treatment at a South African township TB clinic. Sputum TB isolates were characterised by IS61110-based restriction fragment length polymorphism (RFLP and urines were tested for mycobacteriuria by Xpert® MTB/RIF assay. Results 32/199 (16.1% of patients tested LAM-ELISA positive. Median optical density and proportion testing LAM positive remained unchanged during 2 weeks of treatment and then declined over 24 weeks. LAM was associated with positive sputum smear and culture status, HIV infection and low CD4 cell counts but not proteinuria, RFLP strain or TB treatment outcome. The sensitivity of LAM for TB in HIV-infected patients with CD4 counts of ≥ 200, 100-199, 50-99, and Conclusions Urinary LAM was related to host immune factors, was unrelated to Mtb strain and declined steadily after an initial 2 weeks of TB treatment. The strong association of urine LAM with mycobacteriuria is a new finding, indicating frequent TB involvement of the renal tract in advanced HIV infection.

  13. Therapeutic drug monitoring: how to improve drug dosage and patient safety in tuberculosis treatment

    Full Text Available In this article we describe the key role of tuberculosis (TB treatment, the challenges (mainly the emergence of drug resistance, and the opportunities represented by the correct approach to drug dosage, based on the existing control and elimination strategies. In this context, the role and contribution of therapeutic drug monitoring (TDM is discussed in detail. Treatment success in multidrug-resistant (MDR TB cases is low (62%, with 7% failing or relapsing and 9% dying and in extensively drug-resistant (XDR TB cases is even lower (40%, with 22% failing or relapsing and 15% dying. The treatment of drug-resistant TB is also more expensive (exceeding €50 000 for MDR-TB and €160 000 for XDR-TB and more toxic if compared to that prescribed for drug-susceptible TB. Appropriate dosing of first- and second-line anti-TB drugs can improve the patient's prognosis and lower treatment costs. TDM is based on the measurement of drug concentrations in blood samples collected at appropriate times and subsequent dose adjustment according to the target concentration. The ‘dried blood spot’ technique offers additional advantages, providing the rationale for discussions regarding a possible future network of selected, quality-controlled reference laboratories for the processing of dried blood spots of difficult-to-treat patients from reference TB clinics around the world.

    Full Text Available BackgroundTuberculosis (TB remains a salient public health issue along the U.S./Mexico border. This study seeks to identify the social and structural factors, which are associated with TB disease burden in the binational geographic region. Identification of barriers of treatment completion provides the necessary framework for developing evidence-based interventions that are culturally relevant and context specific for the U.S./Mexico border region.MethodsRetrospective study of data extracted from medical charts (n = 439 from Yuma County Health Department (YCHD (n = 160 and Centro de Salud San Luis Río Colorado (n = 279.

    Isoniazid mono-resistance (IMR) is the most common form of mono-resistance; its world prevalence is estimated to range between 0.0 to 9.5% globally. There is no consensus on how these patients should be treated. To describe the impact of IMR tuberculosis (TB) on treatment outcome and survival among pulmonary TB patients treated under programmatic conditions in Orizaba, Veracruz, Mexico. We conducted a prospective cohort study of pulmonary TB patients in Southern Mexico. From 1995 to 2010 patients with acid-fast bacilli or culture proven Mycobacterium tuberculosis in sputum samples underwent epidemiological, clinical and microbiological evaluation. We included patients who harbored isoniazid mono-resistant (IMR) strains and patients with strains susceptible to isoniazid, rifampicin, ethambutol and streptomycin. All patients were treated following Mexican TB Program guidelines. We performed annual follow-up to ascertain treatment outcome, recurrence, relapse and mortality. Between 1995 and 2010 1,243 patients with pulmonary TB were recruited; 902/1,243 (72.57%) had drug susceptibility testing; 716 (79.38%) harbored pan-susceptible and 88 (9.75%) IMR strains. Having any contact with a person with TB (adjusted odds ratio (aOR)) 1.85, 95% Confidence interval (CI) 1.15-2.96) and homelessness (adjusted odds ratio (aOR) 2.76, 95% CI 1.08-6.99) were associated with IMR. IMR patients had a higher probability of failure (adjusted hazard ratio (HR) 12.35, 95% CI 3.38-45.15) and death due to TB among HIV negative patients (aHR 3.30. 95% CI 1.00-10.84). All the models were adjusted for socio-demographic and clinical variables. The results from our study provide evidence that the standardized treatment schedule with first line drugs in new and previously treated cases with pulmonary TB and IMR produces a high frequency of treatment failure and death due to tuberculosis. We recommend re-evaluating the optimal schedule for patients harboring IMR. It is necessary to strengthen

    The Médecins Sans Frontières project of Uzbekistan has provided multidrug-resistant tuberculosis treatment in the Karakalpakstan region since 2003. Rates of default from treatment have been high, despite psychosocial support, increasing particularly since programme scale-up in 2007. We aimed to determine factors associated with default in multi- and extensively drug-resistant tuberculosis patients who started treatment between 2003 and 2008 and thus had finished approximately 2 years of treatment by the end of 2010. A retrospective cohort analysis of multi- and extensively drug-resistant tuberculosis patients enrolled in treatment between 2003 and 2008 compared baseline demographic characteristics and possible risk factors for default. Default was defined as missing ≥60 consecutive days of treatment (all drugs). Data were routinely collected during treatment and entered in a database. Potential risk factors for default were assessed in univariate analysis using chi-square test and in multivariate analysis with logistic regression. 20% (142/710) of patients defaulted after a median of 6 months treatment (IQR 2.6-9.9). Factors associated with default included severity of resistance patterns (pre-extensively drug-resistant/extensively drug-resistant tuberculosis adjusted odds ratio 0.52, 95%CI: 0.31-0.86), previous default (2.38, 1.09-5.24) and age >45 years (1.77, 1.10-2.87). The default rate was 14% (42/294) for patients enrolled 2003-2006 and 24% (100/416) for 2007-2008 enrolments (p = 0.001). Default from treatment was high and increased with programme scale-up. It is essential to ensure scale-up of treatment is accompanied with scale-up of staff and patient support. A successful first course of tuberculosis treatment is important; patients who had previously defaulted were at increased risk of default and death. The protective effect of severe resistance profiles suggests that understanding disease severity or fear may motivate against default. Targeted

    Few studies have investigated the impact of diabetes mellitus (DM), a globally increasing metabolic disease, on treatment outcomes and long-term survival in patients with multidrug-resistant forms of tuberculosis (MDR-TB). We analyzed outcomes in a large cohort to assess the impact of DM on treatment outcomes of patients with MDR-TB. MDR-TB patients newly diagnosed or retreated between 2000 and 2002 and followed for 8-11 years were retrospectively analyzed with respect to the effect of DM as a comorbidity on their treatment outcome and long-term survival. Of 1,407 patients with MDR-TB, 239 (17.0%) had coexisting DM. The mean age and body mass index were higher in MDR-TB patients with DM [MDR-TBDM(+)] than in those without DM [MDR-TBDM(-)]. Patients with MDR-TB and a comorbidity of DM had a significantly lower treatment success rate than those without a history of DM (36.0 vs. 47.2%, p = 0.002). In addition, DM was the negative predictor for MDR-TB treatment success in multivariate analyses [odds ratio 0.51, 95% confidence interval (CI) 0.26-0.99]. Mean survival times were also lower in MDR-TBDM(+) than in MDR-TBDM(-) patients (102 vs. 114 months, p = 0.001), with DM as a significant predictor of poor long-term survival in multivariate analyses (hazard ratio 1.59, 95% CI 1.01-2.50). Among MDR-TB patients, DM was a relatively common comorbidity. In patients undergoing treatment for MDR-TB and followed for 8-11 years, it was found to be independently associated with an increased risk of both treatment failure and death. Copyright © 2013 S.

    Early diagnosis and prompt effective therapy are crucial for the prevention of tuberculosis (TB) transmission, particularly in regions with high levels of multi-drug resistant TB. This study aimed to evaluate the extent of delay in diagnosis and treatment of TB in Uzbekistan and identify associated risk factors. A cross-sectional study was performed on hospital patients with newly diagnosed TB. The time between the onset of respiratory symptoms and initiation of anti-TB treatment was assessed and delays were divided into patient, health system and total delays. Univariable and multivariable logistic regression analysis was used to evaluate determinants of diagnostic and treatment delay. Among 538 patients enrolled, the median delay from onset of symptoms until treatment with anti-TB drugs was 50 days. Analysis of the factors affecting health-seeking behaviour and timely treatment showed the presence of the patient factor. Self-medication was the first health-seeking action for 231 (43%) patients and proved to be a significant predictor of delay (p = 0.005), as well as coughing (p = 0.009), loss of weight (p = 0.001), and visiting private and primary healthcare facilities (p = 0.03 and p = 0.02, respectively). TB diagnostic and treatment delay was mainly contributed to by patient delay and should be reduced through increasing public awareness of TB symptoms and improving public health-seeking behaviour for timely initiation of anti-TB treatment. Efforts should be made to minimise irrational use of antibiotics and support interventions to restrict over-the-counter availability of antibiotics.

    The prison situations are notorious for causing interruptions of tuberculosis (TB) treatment and occurrence of unfavorable outcomes. In Ethiopian prisons, though TB treatment programs exist, treatment outcome results and factors contributing to unsuccessful outcome are not well documented. In this study, we assessed the treatment outcome of TB cases and identified risk factors for unsuccessful outcome in northern Ethiopian prisons. A retrospective record review was conducted for all prisoners diagnosed with TB between September 2011 and August 2015. Outcome variables were defined following WHO guidelines. Out of the 496 patients, 11.5% were cured, 68% completed treatment, 2.5% were lost to follow-up, 1.6% were with a treatment failure, 1.4% died, and 15% were transferred out. All transferred out or released prisoners were not appropriately linked to health facilities and might be lost to treatment follow-up. The overall treatment success rate (TSR) of the 5 years was 94% among the patients who were not transferred out. The odds of unsuccessful outcome were 4.68 times greater among re-treatment cases compared to the newly treated cases. The year of treatment was also associated with variations in TSR; those treated during the earlier year were more likely to have unsuccessful outcome. Sputum non-conversion at the second-month check-up was strongly associated with unsuccessful outcome among the smear-positive cases. The mean TSR of the prisoners in the study prisons was quite satisfactory when gauged against the target level set by the End TB Strategy. However, the lack of appropriate linkage and tracking systems for those prisoners transferred or released before their treatment completion would have a negative implication for the national TB control program as such patients might interrupt their treatment and develop drug-resistant TB. Being in a re-treatment regimen and sputum non-conversion at the second-month check-up were significantly associated with

    Majority of children with tuberculosis are treated in private sector in India with no available data on management practices. The study assessed diagnostic and treatment practices related to childhood pulmonary tuberculosis among paediatricians in Mumbai's private sector in comparison with International Standards for Tuberculosis Care (ISTC) 2009. In this cross-sectional study, 64 paediatricians from private sector filled self-administered questionnaires. Cough was reported as a symptom of childhood TB by 77.8% of respondents. 38.1% request sputum smear or culture for diagnosis and fewer (32.8%) use it for patients positive on chest radiographs and 32.8% induce sputum for those unable to produce it. Sputum negative TB suspect is always tested with X-ray or tuberculin skin test. 61.4% prescribe regimen as recommended in ISTC and all monitor progress to treatment clinically. Drug-resistance at beginning of treatment is suspected for child in contact with a drug-resistant patient (67.7%) and with prior history of antitubercular treatment (12.9%). About half of them (48%) request drug-resistance test for rifampicin in case of nonresponse after two to three months of therapy and regimen prescribed by 41.7% for multidrug-resistant TB was as per ISTC. The study highlights inappropriate diagnostic and treatment practices for managing childhood pulmonary TB among paediatricians in private sector.

    To improve involvement of the private sector in the national tuberculosis (TB) programme in Pakistan various public-private mix projects were set up between 2004 and 2009. A retrospective analysis of data was made to study 6 different public-private mix models for TB control in Pakistan and estimate the contribution of the various private providers to TB case notification and treatment outcome. The number of TB cases notified through the private sector increased significantly from 77 cases in 2004 to 37,656 in 2009. Among the models, the nongovernmental organization model made the greatest contribution to case notification (58.3%), followed by the hospital-based model (18.9%). Treatment success was highest for the district-led model (94.1%) and lowest for the hospital-based model (74.2%). The private sector made an important contribution to the national data through the various public-private mix projects. Issues of sustainability and the lack of treatment supporters are discussed as reasons for lack of success of some projects.

    Adherence behavior is a complex phenomenon influenced by diverse personal, cultural, and socioeconomic factors that may vary between communities in different regions. Understanding the factors that influence adherence behavior is essential in predicting which individuals and communities are at risk of nonadherence. This is necessary for supporting resource allocation and intervention planning in disease control programs. Currently, there is no known concrete and unambiguous computational representation of factors that influence tuberculosis (TB) treatment adherence behavior that is useful for prediction. This study developed a computer-based conceptual model for capturing and structuring knowledge about the factors that influence TB treatment adherence behavior in sub-Saharan Africa (SSA). An extensive review of existing categorization systems in the literature was used to develop a conceptual model that captured scientific knowledge about TB adherence behavior in SSA. The model was formalized as an ontology using the web ontology language. The ontology was then evaluated for its comprehensiveness and applicability in building predictive models. The outcome of the study is a novel ontology-based approach for curating and structuring scientific knowledge of adherence behavior in patients with TB in SSA. The ontology takes an evidence-based approach by explicitly linking factors to published clinical studies. Factors are structured around five dimensions: factor type, type of effect, regional variation, cross-dependencies between factors, and treatment phase. The ontology is flexible and extendable and provides new insights into the nature of and interrelationship between factors that influence TB adherence.

    Full Text Available BACKGROUND: Isoniazid (INH resistance is now the most common type of tuberculosis (TB infection resistance worldwide. The aim of this study was to evaluate the clinical characteristics and treatment outcomes of patients with low- and high-concentration INH-monoresistant TB. METHODS: One hundred and thirty-four patients with culture-confirmed INH-monoresistant TB during 2006 January to 2007 December were retrospectively enrolled. INH resistance was classified as either low-concentration or high-concentration resistance according to the critical concentrations of 0.2 µg/mL or 1 µg/mL of INH, respectively. The patients' clinical outcomes, treatment regimens, and treatment duration were analyzed. RESULTS: The treatment success rates between low- and high-concentration INH-resistant TB were similar (81.8% vs. 86.7%. The treatment regimens and treatment duration were similar between both groups. Only a minor percentage of the patients in both groups received 6-month treatment regimens (low vs. high concentration resistance, 9.1% vs. 13.3%; respectively, p = 0.447 The most common reason for treatment duration longer than 6 months was pyrazinamide given for less than 6 months, followed by a delay in clinical response to treatment. Multivariable analysis showed that prior tuberculosis treatment (Odds ratio, 2.82, 95% C.I., 1.02-7.77, p = 0.045 was the only independent risk factor for unsuccessful treatment outcome. CONCLUSION: Different levels of INH resistance did not affect the treatment outcomes of patients with INH-monoresistant tuberculosis. Prolonged Rifampin-containing regimens may achieve those good outcomes in patients with low- and high-concentration INH-monoresistant TB.

    With all of the developments on infectious diseases, tuberculosis (TB) remains a cause of death among people. One of the most promising assembly techniques in nano-technology is "scaffolded DNA origami" to design and construct a nano-scale drug delivery system. Because of the global health problems of tuberculosis, the development of potent new anti-tuberculosis drug delivery system without cross-resistance with known anti-mycobacterial agents is urgently needed. The aim of this study was to design a nano-scale drug delivery system for TB treatment using the DNA origami method. In this study, we presented an experimental research on a DNA drug delivery system for treating Tuberculosis. TEM images were visualized with an FEI Tecnai T12 BioTWIN at 120 kV. The model was designed by caDNAno software and computational prediction of the 3D solution shape and its flexibility was calculated with a CanDo server. Synthesizing the product was imaged using transmission electron microscopy after negative-staining by uranyl formate. We constructed a multilayer 3D DNA nanostructure system by designing square lattice geometry with the scaffolded-DNA-origami method. With changes in the lock and key sequences, we recommend that this system be used for other infectious diseases to target the pathogenic bacteria.

    Full Text Available Introduction: Tuberculosis (TB in Indonesia is still health problem and the prevalence rate is high. Discontinuing medication and lack of family support are the causalities. Numbers of strategies to overcome are seemingly not succeeded. Roles and responsibilities of family nursing are crucial to improve participation, motivation of individual, family and community in prevention, including pulmonary tuberculosis. Unfortunately, models of pulmonary tuberculosis currently unavailable. The combination of adaptation and conservation in complementarily improving family support and compliance in medication is introduced in this study. Method: This research intended to analyze Adaptive Conservation Model (ACM in extending family support and treatment compliance. Modeling steps including model analysis, expert validation, field trial, implementation and recommending the output model. Research subject involves 15 families who implement family Assistance and supervision in Medication (ASM and other 15 families with ACM. Result: The study revealed ACM is better than ASM on the case of family support and medication compliances. It supports the role of environment as influential factor on individual health belief, values and decision making. Therefore, it is advised to apply ACM in enhancing family support and compliance of pulmonary TB patients. Discussion: Social and family supports to ACM group obtained by developing interaction through communication. Family interaction necessary to improve family support to pulmonary tuberculosis patients. And social support plays as motivator to maintain compliance on medication

    Objective To determine the case-fatality rate (CFR) at the end of the intensive phase of tuberculosis (TB) treatment, and factors associated with fatality. Methods TB patients diagnosed between 2006 and 2013 were followed-up during treatment. We computed the CFR at the end of the intensive phase of TB treatment, and the incidence of death per 100 person-days (pd) of follow-up. We performed survival analysis using the Kaplan-Meier method and Cox regression, and calculate hazard ratios (HR) and 95% confidence intervals (CI). Results A total of 5,182 patients were included, of whom 180 (3.5%) died; 87 of these deaths (48.3%) occurred during the intensive phase of treatment, with a CFR of 1.7%. The incidence of death was 0.028/100 pd. The following factors were associated with death during the intensive phase: being >50 years (HR = 36.9;CI:4.8–283.4); being retired (HR = 2.4;CI:1.1–5.1); having visited the emergency department (HR = 3.1;CI:1.2–7.7); HIV infection (HR = 3.4;CI:1.6–7.2); initial standard treatment with 3 drugs (HR = 2.0;CI:1.2–3.3) or non-standard treatments (HR = 2.68;CI:1.36–5.25); comprehension difficulties (HR = 2.8;CI:1.3–6.1); and smear-positive sputum (HR = 2.3-CI:1.0–4.8). Conclusion There is a non-negligible CFR during the intensive phase of TB, whose reduction should be prioritised. The CFR could be a useful indicator for evaluating TB programs. PMID:27487189

    Full Text Available Abstract Background Charging for tuberculosis (TB treatment could reduce completion rates, particularly in the poor. We identified and synthesised studies that measure costs of TB treatment, estimates of adherence and the potential impact of charging on treatment completion in China. Methods Inclusion criteria were primary research studies, including surveys and studies using qualitative methods, conducted in mainland China. We searched MEDLINE, PUBMED, EMBASE, Science Direct, HEED, CNKI to June 2010; and web pages of relevant Chinese and international organisations. Cost estimates were extracted, transformed, and expressed in absolute values and as a percentage of household income. Results Low income patients, defined at household or district level, pay a total of US$ 149 to 724 (RMB 1241 to 5228 for medical costs for a treatment course; as a percentage of annual household income, estimates range from 42% to 119%. One national survey showed 73% of TB patients at the time of the survey had interrupted or suspended treatment, and estimates from 9 smaller more recent studies showed that the proportion of patients at the time of the survey who had run out of drugs or were not taking them ranged from 3 to 25%. Synthesis of surveys and qualitative research indicate that cost is the most cited reason for default. Conclusions Despite a policy of free drug treatment for TB in China, health services charge all income groups, and costs are high. Adherence measured in cross sectional surveys is often low, and the cumulative failure to adhere is likely to be much higher. These findings may be relevant to those concerned with the development and spread of multi-drug resistant TB. New strategies need to take this into account and ensure patient adherence.

    We investigated the effects of diabetes and the presence of lung cavities on treatment outcomes in patients with pulmonary tuberculosis. We conducted a retrospective review of the clinical records of all consecutive patients admitted to the Kanagawa Cardiovascular and Respiratory Centre with the diagnosis of pulmonary tuberculosis. The study outcomes examined were time to sputum culture conversion and percentage of patients with sputum culture conversion by the time 2 months of treatment, and these outcomes were compared between patients with and without diabetes. Of the 260 patients enrolled in the study, 69 were diagnosed as having diabetes mellitus, while the remaining 191 did not have diabetes. The percentage of patients with cavities was higher in the patients with diabetes (71.0%) than in those without (45.5%; P = 0.0003). The time to sputum culture conversion was significantly longer in the patients with diabetes than in those without (P = 0.0005), and the percentage of patients with a positive sputum culture at 2 months was higher in the patients with diabetes (43.5%) than in those without (18.8%; P = 0.0001). Multivariate analyses revealed that the presence/absence of lung cavities was a more important determinant of treatment outcomes than the presence/absence of diabetes. The presence of lung cavities was found to be a more important determinant of the treatment outcomes than that of diabetes per se in patients with pulmonary tuberculosis. © 2014 The Authors.

    Tuberculosis (TB) is responsible for significant morbidity and mortality worldwide. Even after successful microbiological cure of TB, many patients are left with residual pulmonary damage that can lead to chronic respiratory impairment and greater risk of additional TB episodes due to reinfection with Mycobacterium tuberculosis. Elevated levels of the proinflammatory cytokine tumor necrosis factor-α and several other markers of inflammation, together with expression of matrix metalloproteinases, have been associated with increased risk of pulmonary fibrosis, tissue damage, and poor treatment outcomes in TB patients. In this study, we used a rabbit model of pulmonary TB to evaluate the impact of adjunctive immune modulation, using a phosphodiesterase-4 inhibitor that dampens the innate immune response, on the outcome of treatment with the antibiotic isoniazid. Our data show that cotreatment of M. tuberculosis infected rabbits with the phosphodiesterase-4 inhibitor CC-3052 plus isoniazid significantly reduced the extent of immune pathogenesis, compared with antibiotic alone, as determined by histologic analysis of infected tissues and the expression of genes involved in inflammation, fibrosis, and wound healing in the lungs. Combined treatment with an antibiotic and CC-3052 not only lessened disease but also improved bacterial clearance from the lungs. These findings support the potential for adjunctive immune modulation to improve the treatment of pulmonary TB and reduce the risk of chronic respiratory impairment.

    Multiple sclerosis is an inflammatory and neurodegenerative demyelinating disease. Current treatment of multiple sclerosis focuses on the use of immunomodulatory, immunosuppressant, and selective immunosuppressant agents. Some of these medications may result in high risk of opportunistic infections including tuberculosis. The purpose of this study was to obtain consensus from a panel of neurologists, pulmonologists, infectious disease specialists, and epidemiology experts regarding the diagnosis, treatment, and monitoring of latent tuberculosis in patients with multiple sclerosis. A panel of experts in multiple sclerosis and tuberculosis was established. The methodological process was performed in three phases: definition of questions, answer using Delphi methodology, and the discussion of questions not agreed. Tuberculosis screening is suggested when multiple sclerosis drugs are prescribed. The recommended tests for latent tuberculosis are tuberculin and interferon gamma release test. When an anti-tuberculosis treatment is indicated, monitoring should be performed to determine liver enzyme values with consideration of age as well as comorbid conditions such as a history of alcoholism, age, obesity, concomitant hepatotoxic drugs, and history of liver disease. Latent tuberculosis should be considered in patients with multiple sclerosis who are going to be treated with immunomodulatory and immunosuppressant medications. Transaminase level monitoring is required on a periodic basis depending on clinical and laboratory characteristics. In addition to the liver impairment, other side effects should be considered when Isoniazid is prescribed.

    An economic study was conducted alongside a clinical trial at three sites in Pakistan to establish the costs and effectiveness of different strategies for implementing directly observed treatment (DOT) for tuberculosis. Patients were randomly allocated to one of three arms: DOTS with direct observation by health workers (at health centres or by community health workers); DOTS with direct observation by family members; and DOTS without direct observation. The clinical trial found no statistically significant difference in cure rate for the different arms. The economic study collected data on the full range of health service costs and patient costs of the different treatment arms. Data were also disaggregated by gender, rural and urban patients, by treatment site and by economic categories, to investigate the costs of the different strategies, their cost-effectiveness and the impact that they might have on patient compliance with treatment. The study found that direct observation by health centre-based health workers was the least cost-effective of the strategies tested (US dollars 310 per case cured). This is an interesting result, as this is the model recommended by the World Health Organization and International Union against Tuberculosis and Lung Disease. Attending health centres daily during the first 2 months generated high patient costs (direct and in terms of time lost), yet cure rates for this group fell below those of the non-observed group (58%, compared with 62%). One factor suggested by this study is that the high costs of attending may be deterring patients, and in particular, economically active patients who have most to lose from the time taken by direct observation. Without stronger evidence of benefits, it is hard to justify the costs to health services and patients that this type of direct observation imposes. The self-administered group came out as most cost-effective (164 dollars per case cured). The community health worker sub-group achieved the

    Full Text Available ABSTRACT Objective To assess the implementation of HIV-related interventions for patients with tuberculosis (TB, as well as TB treatment outcomes in patients coinfected with HIV in Brazil in 2011. Methods This was a cross-sectional, operational research study of HIV-related interventions among TB cases and the sociodemographic and clinical characteristics of TB-HIV coinfected patients. It also used a retrospective cohort design to determine the association between antiretroviral therapy (ART and favorable TB treatment outcomes. The source of data was a linkage of 2011 administrative health databases used by the National TB and HIV/AIDS Programs. Results Of 73 741 new cases of TB reported, 63.6% (46 865 patients were tested for HIV; 10.3% were positive. Of patients with HIV, 45.9% or 3 502 were on ART. TB favorable outcome was achieved in 63.1% or 2 205 coinfected patients on ART and in only 35.4% or 1 459 of those not on ART. On multivariate analysis, the relative risk for the association between ART and TB treatment success was 1.72 (95% Confidence Interval = 1.64–1.81. Conclusions The linkage between national TB and HIV datasets has created a convenient baseline for ongoing monitoring of HIV testing, ART use, and TB treatment outcomes among coinfected patients. The low rates of HIV screening and ART use in 2011 need to be improved. The association between ART and treatment success adds to the evidence supporting timely initiation of ART for all patients with TB-HIV coinfection.

    Diabetes is a risk factor for active tuberculosis (TB). Data are limited regarding the association between diabetes and TB drug resistance and treatment outcomes. We examined characteristics of TB patients with and without diabetes in a Peruvian cohort at high risk for drug-resistant TB. Among TB patients with diabetes (TB-DM), we studied the association between diabetes clinical/management characteristics and TB drug resistance and treatment outcomes. During 2005-2008, adults with suspected TB with respiratory symptoms in Lima, Peru, who received rapid drug susceptibility testing (DST), were prospectively enrolled and followed during treatment. Bivariate and Kaplan-Meier analyses were used to examine the relationships of diabetes characteristics with drug-resistant TB and TB outcomes. Of 1671 adult TB patients enrolled, 186 (11.1%) had diabetes. TB-DM patients were significantly more likely than TB patients without diabetes to be older, have had no previous TB treatment, and to have a body mass index (BMI) >18.5 kg/m(2) (pdiabetes, and 12% and 28%, respectively, among TB-DM patients. Among 149 TB-DM patients with DST results, 104 (69.8%) had drug-susceptible TB and 45 (30.2%) had drug-resistant TB, of whom 29 had multidrug-resistant TB. There was no association between diabetes characteristics and drug-resistant TB. Of 136 TB-DM patients with outcome information, 107 (78.7%) had a favorable TB outcome; active diabetes management was associated with a favorable outcome. Diabetes was common in a cohort of TB patients at high risk for drug-resistant TB. Despite prevalent multidrug-resistant TB among TB-DM patients, the majority had a favorable TB treatment outcome.

    Full Text Available STUDY DESIGN: A retrospective clinical study. OBJECTIVE: To evaluate the clinical efficacy of the surgical treatment of noncontiguous spinal tuberculosis (NSTB, and to discuss its therapeutic strategies. METHODS: We performed a retrospective review of clinical and radiographic data that were prospectively collected on 550 consecutive spinal tubercular patients including 27 patients who were diagnosed and treated as NSTB in our institution from June 2005 to June 2011. Apart from 4 patients being treated conservatively, the remainder received surgery by posterior transforaminal debridement, interbody fusion with instrumentation, posterior instrumentation and anterior debridement with fusion in a single or two-stage operation. The clinical outcomes were evaluated before and after treatment in terms of hematologic and radiographic examinations, bone fusion and neurologic status. The Oswestry Disability Index score was determined before treatment and at the last follow-up visit. RESULTS: 23 patients (15 M/8F, averaged 44.6 ± 14.2 years old (range, 19 to 70 yd, who received surgical treatment, were followed up after surgery for a mean of 52.5 ± 19.5 months (range, 24 to 72 months. The kyphotic angle was changed significantly between pre- and postoperation (P<0.05. The mean amount of correction was 12.6 ± 7.2 degrees, with a small loss of correction at last follow-up. All patients achieved solid bone fusion. No patients with neurological deficit deteriorated postoperatively. Neither mortalities nor any major complications were found. There was a significant difference of Oswestry Disability Index scores between preoperation and the final follow-up. CONCLUSION: The outcomes of follow-up showed that posterior and posterior-anterior surgical treatment methods were both viable surgical options for NSTB. Posterior transforaminal debridement, interbody fusion and posterior instrumentation, as a less invasive technique, was feasible and effective to treat

    The incidence of tuberculosis (TB) in end-stage renal disease is significantly higher than that in the general population. Among those with kidney dysfunction, anti-TB treatment is associated with increased side effects, but the effect on healthcare utilization is unknown. Methods/Aim: To assess patient-reported symptoms, adverse effects and describe changes in healthcare utilization patterns during treatment for TB, we conducted a case series (n = 12) of patients receiving maintenance hemodialysis (HD) from Mayo Clinic Dialysis Services and concurrent drug therapy for TB from January 2002 through May 2014. Healthcare utilization (hospitalizations and emergency department (ED) visits independent of hospital admission) was compared before and during treatment. Patients were treated for latent (n = 7) or active (n = 5) TB. The majority of patients with latent disease were treated with isoniazid (n = 5, 71%), while active-disease patients received a 4-drug regimen. Adverse effects were reported in 83% of patients. Compared to measurements prior to drug initiation, serum albumin and dialysis weights were similar at 3 months. Commonly reported anti-TB drug toxicities were described. More than half (58%) of the patients were hospitalized at least once. No ED or hospital admissions occurred in the period prior to drug therapy, but healthcare utilization increased during treatment in the latent disease group (hospitalization rate per person-month: pre 0 vs. post 1). Among HD patients, anti-TB therapy is associated with frequently reported symptoms and increased healthcare utilization. Among this subset, patients receiving treatment for latent disease may be those with greatest increase in healthcare use. Careful monitoring and early complication detection may help optimize medication adherence and minimize hospitalizations. © 2016 S. Karger AG, Basel.

    China has more and more floating population because of reform and opening-up. As one of the high burden countries in tuberculosis (TB) control in the world, China has to face more challenges about the TB case detection and treatment among floating population in China. Aim to evaluate the effect of case detection and treatment of the Floating Population TB Control Pilot Project from Global Fund Round Five (GFR5) TB Control Program in China. During October 2006 to September 2008, the pilot project was implemented gradually in 60 counties in Tianjin, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong and Guangdong. All quarterly reports of the pilot project were collected, and these materials were summarized and analyzed. In seven coastal provinces, 19,584 active pulmonary TB (PTB) cases were registered among floating population in 2 years. Among the active PTB cases, 87.2% were 15-45 years old, and 62.8% were male. In second year, 15,629 active PTB cases were registered, and the overall registration rate was 68 per 100,000 people. DOT treatments were provided for 18,125 active PTB cases in 2 years, and overall DOT treatment rate was 92.6%. There were 3,955 active PTB cases registered in first year, and the overall cure rate was 86.0%. Through the implementation of the pilot project, the TB case detection and treatment among floating population have been enhanced in pilot areas of China. The useful experience and results from the pilot project have been being gradually generalized nationally.

    To evaluate patients' profiles, demographics, clinical and therapeutic approaches and strategies in patients with tuberculous lymphadenitis (TBG). A retrospective study of all TBG-confirmed cases admitted in a tuberculosis-specific health care facility between 1 January 2009 and 16 June 2013. A total of 181 clinical files were examined. Mean age was 32years old; the female/male ratio was 1.78 to 1. Raw milk consumption was noted in 1/3 of patients. Most cases involved the head and neck region (83.4%), nodes involvement, including axillary (12 cases), and mediastinal (9 cases). Clinical symptoms were present in only 55.2%. Tuberculin skin test (TST) was conducted with 82.6% positive responses. Diagnostics confirmation was done with anatomical pathology in most of the patients; only 56 of them had any microbiology analysis done. Demonstration of acid-fast bacilli in microscopy from either fine-needle aspirates or biopsies was done in 17.5% of cases, and cultures yielded positive results in 27%. Treatment duration was varied. Paradoxical reactions were noted in 12% and persistent lymphadenopathy after treatment completion was noted in 10% of cases. TBG remains a disease of interest. Today, its diagnosis and management is still a problem despite its increasing worldwide incidence, and especially in this study area. Disease control should be strengthened in this country.

    This study aimed to evaluate the risk factors for tuberculosis (TB) treatment default in a priority city for disease control in Brazil. A cohort of TB cases diagnosed from 2008 to 2009 was followed up from patients' entry into three outpatient sites, in Juiz de Fora, Minas Gerais (Brazil), until the recording of the outcomes. Drug addiction, alcoholism and treatment site appeared to be independently associated with default. Current users of crack as the hardest drug (odds ratio (OR) 12·25, 95% confidence interval (CI) 3·04-49·26) were more likely to default than other hard drug users (OR 5·67, 95% CI 1·34-24·03), former users (OR 4·12, 95% CI 1·11-15·20) and those not known to use drugs (reference group). Consumers at high risk of alcoholism (OR 2·94, 95% CI 1·08-7·99) and those treated in an outpatient hospital unit (OR 8·22, 95% CI 2·79-24·21%) also were more likely to default. Our results establish that substance abuse was independently associated with default. National TB programmes might be more likely to achieve their control targets if they include interventions aimed at improving adherence and cure rates, by diagnosing and treating substance abuse concurrently with standard TB therapy.

    This study seeks to analyze the process of detection and treatment of cases of tuberculosis (TB) in a prison in the south of Brazil. An active and passive search for TB was conducted to estimate the scale of TB in a prison with 764 inmates. In conjunction with the detection strategies and clinical follow-up of the 41 TB cases, participant observation and records in field diaries were performed, making it possible to analyze the scope and limitations of detection and treatment of cases of TB in prison. The development of search strategies is discussed along with the use of questionnaires to detect symptomatic cases, as well as the inadequacy of the clinical follow-up of TB cases, involvement of different workers and coordination between prison and health services. There is clear potential for the control of TB using an active search to induce the passive detection and screening for symptoms that - even skewed by the perceptions of inmates regarding symptoms of TB - enabled an increase in detection. The functional dynamics of prison life hamper the inclusion of health routines and can restrict actions to control TB and other diseases. In the process of control of TB in prisons, the feasibility of effective detection methods is as important as planning based on disease conditions, network services and workers involved.

    Full Text Available Objectives. To evaluate tomographic changes in pulmonary tuberculosis (TB, degree of agreement among three radiologists regarding tomographic diagnoses, and sequelae following treatment. Methods. Cross-sectional and descriptive study of 74 TB patients confirmed by sputum culture and chest computed tomography before (CT1 and 6 months after (CT2 drug therapy. Results were performed by three radiologists blinded to clinical and laboratory results. Results. Main findings in CT1 included nodules indicating the presence of a tree-in-bud pattern in 93% of cases, ill-defined nodules in 84% of cases, consolidation in 77% of cases, architectural distortion in 71% of cases, cavitary lesions in 62% of cases, and ground glass opacities in 37% of cases. Airway involvement, characterized by increased thickness and dilatation of the bronchial walls, occurred in 93% of cases. Pleural involvement occurred in 54%. There was an agreement on active TB among the three radiologists in 85% of cases. The results in CT2 indicated the presence of architectural distortion in 91% of cases and cylindrical bronchiectasis in 86%. Conclusions. The study established a tomographic pattern for diagnosis of active TB characterized by the presence of airway nodules, consolidation, architectural distortion, and cavitary lesions, and an almost complete degree of agreement (Kappa was observed among the radiologists (0.85.

    Objective: To evaluate the effect and safety of intraluminal stent implantation in the treatment of complete airway obstruction with unilateral pulmonary atelectasis caused by endobronchial tuberculosis (EBTB). Methods: 9 cases of pulmonary atelectasis caused by EBTB were treated with high- frequency electricity/microwave, balloon dilation and endobronchial stent implantation. At the time of 1 week and 4-6 months after stenting ,the diameters of stenotic segment were measured. Results: All 9 cases with atelectasis of EBTB showed complete re-expansion within 3 days after the stent implantation. The mean diameter of the stenotic segments of 9 EBTB patients increased to 9.17 ± 1.24 mm at 7th day after stent implantation; 3 of 9 EBTB patients occured mild restenosis after implantation of tracheobronchial stents. However, combination therapy of cryotherapy and balloon dilation can effectively prevent the aggravation of restenosis. Conclusion: Comparing with traditional surgical treatment, the intraluminal stent implantation for atelectasis caused by EBTB is a new, effective, safe and microtraumatic method with reliable preservation of pulmonary function.

Eight key informants were selected by snowball sampling technique and data about medicinal plants were collected by semistructured interviews, participatory observations, and focus group. Qualitative analysis was undertaken using thematic analysis. There were 23 species of plants (22 genera, 20 families) documented and herbarium specimens were deposited at the UTHM Herbarium. Dipterocarpus sublamellatus was recorded for the first time with ethnomedical uses while other species were previously reported. The qualitative approach employed in this study demonstrates the emic perspective in terms of perceptions on traditional herbal medicine, transfer of knowledge, significant taboos related with medicinal plants, and their conservation efforts. Local and biomedical terminology in treatment of TB showed substantial correspondence. The outcomes obtained in the study are worth being further investigated for conservation strategies and are worthy of verifying their ethnomedical claims scientifically.

To determine 1) at national level between 2011 and 2013, the relationship between human immunodeficiency virus (HIV) testing, uptake of TB-HIV interventions and adverse treatment outcomes among TB-HIV patients; and 2) in HCMC in 2013, patient characteristics associated with adverse outcomes. An ecological study reviewing aggregate nationwide data and a retrospective cohort review in HCMC. Nationwide, from 2011 to 2013, HIV testing increased in TB patients from 58% to 68% and antiretroviral therapy (ART) increased in TB-HIV patients from 54% to 63%. Adverse treatment outcomes in TB-HIV patients increased from 24% to 27%, largely due to transfer out (5-9% increase) and death. The Northern and Highland regions showed poor uptake of TB-HIV interventions. In HCMC, 303 (27%) of 1110 TB-HIV patients had adverse outcomes, with higher risks observed in those with previously treated TB, those diagnosed as HIV-positive before TB onset and those never placed on cotrimoxazole or ART. Despite improving HIV testing rates and TB-HIV interventions, adverse outcomes in TB-HIV patients remain at about 26%. Characteristics predicting higher risk of adverse outcomes must be addressed if Viet Nam wishes to end the TB epidemic by 2030.

    A biomarker indicating successful tuberculosis (TB) therapy would assist in determining appropriate length of treatment. This study aimed to determine changes in mycobacteria-specific antigen-induced cytokine biomarkers in patients receiving therapy for latent or active TB, to identify biomarkers potentially correlating with treatment success. A total of 33 adults with active TB and 36 with latent TB were followed longitudinally over therapy. Whole blood stimulation assays using mycobacteria-specific antigens (CFP-10, ESAT-6, PPD) were done on samples obtained at 0, 1, 3, 6 and 9 months. Cytokine responses (IFN-γ, IL-1ra, IL-2, IL-10, IL-13, IP-10, MIP-1β, and TNF-α) in supernatants were measured by Luminex xMAP immunoassay. In active TB cases, median IL-1ra (with CFP-10 and with PPD stimulation), IP-10 (CFP-10, ESAT-6), MIP-1β (ESAT-6, PPD), and TNF-α (ESAT-6) responses declined significantly over the course of therapy. In latent TB cases, median IL-1ra (CFP-10, ESAT-6, PPD), IL-2 (CFP-10, ESAT-6), and IP-10 (CFP-10, ESAT-6) responses declined significantly. Mycobacteria-specific cytokine responses change significantly over the course of therapy, and their kinetics in active TB differ from those observed in latent TB. In particular, mycobacteria-specific IL-1ra responses are potential correlates of successful therapy in both active and latent TB. Copyright © 2017 The British Infection Association.

MDR is strictly a man made problem. Poor prescriptions, poor case management, lack of coordinated education and haphazard treatment research result in drug resistance. Treatment of MDR is difficult. The drug acceptability, tolerance and toxicity have to be considered. HIV and tuberculosis form a deadly duo. They mean more cases, more costs and more national losses.

    This study explored the effect of screening and treatment of refugees for latent tuberculosis infection (LTBI) before entrance to the United States as a strategy for reducing active tuberculosis (TB). The purpose of this study was to estimate the costs and benefits of LTBI screening and treatment in United States bound refugees prior to arrival. Costs were included for foreign and domestic LTBI screening and treatment and the domestic treatment of active TB. A decision tree with multiple Markov nodes was developed to determine the total costs and number of active TB cases that occurred in refugee populations that tested 55, 35, and 20 % tuberculin skin test positive under two models: no overseas LTBI screening and overseas LTBI screening and treatment. For this analysis, refugees that tested 55, 35, and 20 % tuberculin skin test positive were divided into high, moderate, and low LTBI prevalence categories to denote their prevalence of LTBI relative to other refugee populations. For a hypothetical 1-year cohort of 100,000 refugees arriving in the United States from regions with high, moderate, and low LTBI prevalence, implementation of overseas screening would be expected to prevent 440, 220, and 57 active TB cases in the United States during the first 20 years after arrival. The cost savings associated with treatment of these averted cases would offset the cost of LTBI screening and treatment for refugees from countries with high (net cost-saving: $4.9 million) and moderate (net cost-saving: $1.6 million) LTBI prevalence. For low LTBI prevalence populations, LTBI screening and treatment exceed expected future TB treatment cost savings (net cost of $780,000). Implementing LTBI screening and treatment for United States bound refugees from countries with high or moderate LTBI prevalence would potentially save millions of dollars and contribute to United States TB elimination goals. These estimates are conservative since secondary transmission from tuberculosis cases

     No treatment regimens have been specifically designed for children, in whom tuberculosis is predominantly intracellular. Given their activity as monotherapy and their ability to penetrate many diseased anatomic sites that characterize disseminated tuberculosis, linezolid and moxifloxacin could be combined to form a regimen for this need.  We examined microbial kill of intracellular Mycobacterium tuberculosis (Mtb) by the combination of linezolid and moxifloxacin multiple exposures in a 7-by-7 mathematical matrix. We then used the hollow fiber system (HFS) model of intracellular tuberculosis to identify optimal dose schedules and exposures of moxifloxacin and linezolid in combination. We mimicked pediatric half-lives and concentrations achieved by each drug. We sampled the peripheral compartment on days 0, 7, 14, 21, and 28 for Mtb quantification, and compared the slope of microbial kill of Mtb by these regimens to the standard regimen of isoniazid, rifampin, and pyrazinamide, based on exponential decline regression.  The full exposure-response surface identified linezolid-moxifloxacin zones of synergy, antagonism, and additivity. A regimen based on each of these zones was then used in the HFS model, with observed half-lives of 4.08 ± 0.66 for linezolid and 3.80 ± 1.34 hours for moxifloxacin. The kill rate constant was 0.060 ± 0.012 per day with the moxifloxacin-linezolid regimen in the additivity zone vs 0.083 ± 0.011 per day with standard therapy, translating to a bacterial burden half-life of 11.52 days vs 8.53 days, respectively.  We identified doses and dose schedules of a linezolid and moxifloxacin backbone regimen that could be highly efficacious in disseminated tuberculosis in children. © The Author 2016.

    Tuberculosis of the orbit is rare, even in places where tuberculosis is endemic. The disease may involve soft tissue, the lacrimal gland, or the periosteum or bones of the orbital wall. Intracranial extension, in the form of extradural abscess, and infratemporal fossa extension has been described. This pictorial essay illustrates the imaging findings of nine histopathologically confirmed cases of orbital tuberculosis. All these patients responded to antituberculous treatment

    Background Expanding latent tuberculosis treatment is important to decrease active disease globally. Once-weekly isoniazid and rifapentine for 12 doses is effective but limited by requiring direct observation. Objective To compare treatment completion and safety of once-weekly isoniazid and rifapentine by self-administration versus direct observation. Design An open-label, phase 4 randomized clinical trial designed as a noninferiority study with a 15% margin. Seventy-five percent or more of study patients were enrolled from the United States for a prespecified subgroup analysis. (ClinicalTrials.gov: NCT01582711) Setting Outpatient tuberculosis clinics in the United States, Spain, Hong Kong, and South Africa. Participants 1002 adults (aged ≥18 years) recommended for treatment of latent tuberculosis infection. Intervention Participants received once-weekly isoniazid and rifapentine by direct observation, self-administration with monthly monitoring, or self-administration with weekly text message reminders and monthly monitoring. Measurements The primary outcome was treatment completion, defined as 11 or more doses within 16 weeks and measured using clinical documentation and pill counts for direct observation, and self-reports, pill counts, and medication event–monitoring devices for self-administration. The main secondary outcome was adverse events. Results Median age was 36 years, 48% of participants were women, and 77% were enrolled at the U.S. sites. Treatment completion was 87.2% (95% CI, 83.1% to 90.5%) in the direct-observation group, 74.0% (CI, 68.9% to 78.6%) in the self-administration group, and 76.4% (CI, 71.3% to 80.8%) in the self-administration–with–reminders group. In the United States, treatment completion was 85.4% (CI, 80.4% to 89.4%), 77.9% (CI, 72.7% to 82.6%), and 76.7% (CI, 70.9% to 81.7%), respectively. Self-administered therapy without reminders was noninferior to direct observation in the United States; no other comparisons met

    Antimicrobial resistance is a major global concern. Tuberculosis (TB) strains resistant to rifampicin and other TB medicines challenge patient survival and public health. The World Health Organization (WHO) has published treatment guidelines for drug-resistant TB since 1997 and last updated them in 2016 based on reviews of aggregated and individual patient data from published and unpublished studies. An international expert panel formulated recommendations following the GRADE approach. The new WHO guidelines recommend a standardised 9-12 months shorter treatment regimen as first choice in patients with multidrug- or rifampicin-resistant TB (MDR/RR-TB) strains not resistant to fluoroquinolones or second-line injectable agents; resistance to these two classes of core second-line medicines is rapidly detectable with molecular diagnostics also approved by WHO in 2016. The composition of longer regimens for patients ineligible for the shorter regimen was modified. A first-ever meta-analysis of individual paediatric patient data allowed treatment recommendations for childhood MDR/RR-TB to be made. Delamanid is now also recommended in patients aged 6-17 years. Partial lung resection is a recommended option in MDR/RR-TB care. The 2016 revision highlighted the continued shortage of high-quality evidence and implementation research, and reiterated the need for clinical trials and best-practice studies to improve MDR/RR-TB patient treatment outcomes and strengthen policy.

    To summarize the costs of tuberculosis (TB) diagnosis and treatment in human immunodeficiency virus (HIV)-infected patients and to assess the methodological quality of these studies. We included cost, cost-effectiveness, and cost-utility studies that reported primary costing data, conducted worldwide and published between 1990 and August 2016. We retrieved articles in PubMed, Embase, EconLit, CINAHL plus, and LILACS databases. The quality assessment was performed using two guidelines-the Consolidated Health Economic Evaluation Reporting Standards and the Tool to Estimate Patient's Costs. TB diagnosis was reported as cost per positive result or per suspect case. TB treatment was reported as cost of TB drugs, TB/HIV hospitalization, and treatment. We analyzed the data per level of TB/HIV endemicity and perspective of analysis. We included 34 articles, with 24 addressing TB/HIV treatment and 10 addressing TB diagnosis. Most of the studies were carried out in high TB/HIV burden countries (82%). The cost of TB diagnosis per suspect case varied from $0.5 for sputum smear microscopy to $175 for intensified case finding. The cost of TB/HIV hospitalization was higher in low/medium TB/HIV burden countries than in high TB/HIV burden countries ($75,406 vs. $2,474). TB/HIV co-infection presented higher costs than TB from the provider perspective ($814 vs. $604 vs. $454). Items such as "choice of discount rate," "patient interview procedures," and "methods used for valuing indirect costs" did not achieve a good score in the quality assessment. Our findings point to the need of generation of more standardized methods for cost data collection to generate more robust estimates and thus, support decision-making process.

    Despite improvements in treatment success rates for tuberculosis (TB), current six-month regimen duration remains a challenge for many National TB Programmes, health systems, and patients. There is increasing investment in the development of shortened regimens with a number of candidates in phase 3 trials. We developed an individual-based decision analytic model to assess the cost-effectiveness of a hypothetical four-month regimen for first-line treatment of TB, assuming non-inferiority to current regimens of six-month duration. The model was populated using extensive, empirically-collected data to estimate the economic impact on both health systems and patients of regimen shortening for first-line TB treatment in South Africa, Brazil, Bangladesh, and Tanzania. We explicitly considered 'real world' constraints such as sub-optimal guideline adherence. From a societal perspective, a shortened regimen, priced at USD1 per day, could be a cost-saving option in South Africa, Brazil, and Tanzania, but would not be cost-effective in Bangladesh when compared to one gross domestic product (GDP) per capita. Incorporating 'real world' constraints reduces cost-effectiveness. Patient-incurred costs could be reduced in all settings. From a health service perspective, increased drug costs need to be balanced against decreased delivery costs. The new regimen would remain a cost-effective option, when compared to each countries' GDP per capita, even if new drugs cost up to USD7.5 and USD53.8 per day in South Africa and Brazil; this threshold was above USD1 in Tanzania and under USD1 in Bangladesh. Reducing the duration of first-line TB treatment has the potential for substantial economic gains from a patient perspective. The potential economic gains for health services may also be important, but will be context-specific and dependent on the appropriate pricing of any new regimen.

    Full Text Available Abstract Background Tuberculosis (TB is a major public health problem in Africa with Ethiopia being the most affected. Treatment delay is an important indicator of access to TB diagnosis and treatment. However, little is known about factors associated with treatment delay of pulmonary TB among pastoralists. Health facility based cross sectional study was conducted on 129 pulmonary TB patients in pastoralist community. The study was conducted in three health centers and a hospital. Time between onset of TB symptoms and first visit to a professional health care provider (patient delay, and the time between first visits to the professional health care provider to the date of diagnosis (provider's delay were analyzed using SPSS 16.0 statistical software. Findings A total of 129 new smear positive pulmonary TB patients participated in the study. The median total delay was 97 days. The median patient and health provider delays were 63 and 34 days, respectively. Ninety six percent of the patients were delayed for more than the twenty one days cutoff point. Patient delay was positively associated with first visit to traditional healer/private clinic/drug shop, rural residence, being illiterate, living in more than 10 kilometers from health facility; severity of illness at first presentation to health facility. Provider delay was positively associated with rural residence, being illiterate, patient with good functional status, patients in contact with more than two health providers, and place of first visit being traditional healer/private clinic/drug shop. Conclusions This study showed that majority of smear positive patients delayed either for diagnosis or treatment, thus continue to serve as reservoirs of infection. This indicates that there is a need for intervention to decrease patient and provider delays. Effort to reduce delays in pastoralist communities should focus on improving access to services in rural communities, engaging traditional and

    Vulnerable populations, including homeless persons, high-risk drug and alcohol users, prison inmates and other marginalised populations, contribute a disproportionate burden of tuberculosis (TB) cases in low-incidence settings. Drivers of this disease burden include an increased risk of both TB transmission in congregate settings, and progression from infection to active disease. Late diagnosis and poor treatment completion further propagate the epidemic and fuel the acquisition of drug resistance. These groups are therefore a major priority for TB control programmes in low-incidence settings. Targeted strategies include active case finding (ACF) initiatives and interventions to improve treatment completion, both of which should be tailored to local populations. ACF usually deploys mobile X-ray unit screening, which allows sensitive, high-throughput screening with immediate availability of results. Such initiatives have been found to be effective and cost-effective, and associated with reductions in proxy measures of transmission in hard-to-reach groups. The addition of point-of-care molecular diagnostics and automated X-ray readers may further streamline the screening pathway. There is little evidence to support interventions to improve adherence among these risk groups. Such approaches include enhanced case management and directly observed treatment, while video-observed therapy (currently under evaluation) appears to be a promising tool for the future. Integrating outreach services to include both case detection and case-management interventions that share a resource infrastructure may allow cost-effectiveness to be maximised. Integrating screening and treatment for other diseases that are prevalent among targeted risk groups into TB outreach interventions may further improve cost-effectiveness. This article reviews the existing literature, and highlights priorities for further research.

    Full Text Available Background: Revised National Tuberculosis Control Programme (RNTCP was introduced in the country as a pilot project since 1993 in a phased manner and expanded throughout the country by the year 2005. Although studies have shown the success of RNTCP, data pertaining to the indicators of programme performance in urban and tribal set up are rare. Objectives: The objective of this study was to assess and compare the RNTCP in urban and tribal areas of Maharashtra through the indicators of performance and outcome of the patients. Patients and Methods: A retrospective comparative record-based study was conducted in selected urban and tribal areas' tuberculosis (TB units. Records of patients enrolled newly for TB treatment and those already undergoing treatment under RNTCP from April 2015 to September 2015 (6 months were considered for analysis. Chi-square test and Z-test (test of significance are applied where required by using Epi Info 7 and Microsoft Excel 2010.Results: Sputum smear collection was significantly higher in urban areas (P = 0.001. In urban areas, new TB case detection was 35%, while in tribal areas, it was 42% as per the RNTCP norms. Sputum positivity was marginally more in tribal (5.87% than urban (3.28% areas. Cure rate was more in urban areas than tribal (P = 0.001 areas. There were statistically significantly high default cases in tribal areas. Conclusions: Sputum collection and sputum positivity rate were low in urban and tribal areas, but TB screening, especially in tribal areas, was significantly low. Sputum positivity was significantly higher in tribal areas. Significantly low cure rate and high default rate in tribal area warrant the need for strengthening of RNTCP activities in tribal areas.

    Factors that affect latent tuberculosis infection (LTBI) treatment completion in the US have not been well studied beyond public health settings. This gap was highlighted by recent health insurance-related regulatory changes that are likely to increase LTBI treatment by private sector healthcare providers. We analyzed LTBI treatment completion in the private healthcare setting to facilitate planning around this important opportunity for tuberculosis (TB) control in the US. We analyzed a national sample of commercial insurance medical and pharmacy claims data for people ages 0 to 64 years who initiated daily dose isoniazid treatment between July 2011 and March 2014 and who had complete data. All individuals resided in the US. Factors associated with treatment completion were examined using multivariable generalized ordered logit models and bivariate Kruskal-Wallis tests or Spearman correlations. We identified 1072 individuals with complete data who initiated isoniazid LTBI treatment. Treatment completion was significantly associated with less restrictive health insurance, age Private sector healthcare claims data provide insights into LTBI treatment completion patterns and patient/provider behaviors. Such information is critical to understanding the opportunities and limitations of private healthcare in the US to support treatment completion as this sector's role in protecting against and eliminating TB grows.

    Full Text Available Abstract Background Multidrug-resistant tuberculosis (MDR-TB is a threat for the global TB epidemic control. Despite existing evidence that individualized treatment of MDR-TB is superior to standardized regimens, the latter are recommended in Brazil, mainly because drug-susceptibility tests (DST are often restricted to first-line drugs in public laboratories. We compared treatment outcomes of MDR-TB patients using standardized versus individualized regimens in Brazil, a high TB-burden, low resistance setting. Methods The 2007–2013 cohort of the national electronic database (SITE-TB, which records all special treatments including drug-resistance, was analysed. Patients classified as MDR-TB in SITE-TB were eligible. Treatment outcomes were classified as successful (cure/treatment completed or unsuccessful (failure/relapse/death/loss to follow-up. The odds for successful treatment according to type of regimen were controlled for demographic and clinical variables. Results Out of 4029 registered patients, we included 1972 recorded from 2010 to 2012, who had more complete outcome data. The overall success proportion was 60%. Success was more likely in non-HIV patients, sputum-negative at baseline, with unilateral disease and without prior DR-TB. Adjusted for these variables, those receiving standardized regimens had 2.7-fold odds of success compared to those receiving individualized treatments when failure/relapse were considered, and 1.4-fold odds of success when death was included as an unsuccessful outcome. When loss to follow-up was added, no difference between types of treatment was observed. Patients who used levofloxacin instead of ofloxacin had 1.5-fold odds of success. Conclusion In this large cohort of MDR-TB patients with a low proportion of successful outcomes, standardized regimens had superior efficacy than individualized regimens, when adjusted for relevant variables. In addition to the limitations of any retrospective observational

    Full Text Available Abstract Background The occurrence of tuberculosis (TB, human immunodeficiency virus (HIV, and viral hepatitis infections in the same patient poses unique clinical and public health challenges, because medications to treat TB and HIV are hepatotoxic. We conducted an observational study to evaluate risk factors for HBsAg and/or anti-HCV reactivity and to assess differences in adverse events and TB treatment outcomes among HIV-infected TB patients. Methods Patients were evaluated at the beginning, during, and at the end of TB treatment. Blood samples were tested for aspartate aminotransferase (AST, alanine aminotransferase (ALT, total bilirubin (BR, complete blood count, and CD4+ T lymphocyte cell count. TB treatment outcomes were assessed at the end of TB treatment according to international guidelines. Results Of 769 enrolled patients, 752 (98% had serologic testing performed for viral hepatitis: 70 (9% were reactive for HBsAg, 237 (31% for anti-HCV, and 472 (63% non-reactive for both markers. At the beginning of TB treatment, 18 (26% patients with HBsAg reactivity had elevated liver function tests compared with 69 (15% patients non-reactive to any viral marker (p = 0.02. At the end of TB treatment, 493 (64% were successfully treated. Factors independently associated with HBsAg reactivity included being a man who had sex with men (adjusted odds ratio [AOR], 2.1; 95% confidence interval [CI], 1.1–4.3 and having low TB knowledge (AOR, 1.8; CI, 1.0–3.0. Factors most strongly associated with anti-HCV reactivity were having injection drug use history (AOR, 12.8; CI, 7.0–23.2 and living in Bangkok (AOR, 15.8; CI, 9.4–26.5. The rate of clinical hepatitis and death during TB treatment was similar in patients HBsAg reactive, anti-HCV reactive, both HBsAg and anti-HCV reactive, and non-reactive to any viral marker.

    Mortality in multidrug-resistant (MDR) tuberculosis-human immunodeficiency virus (HIV) coinfection has historically been high, but most studies predated the availability of antiretroviral therapy (ART). We prospectively compared survival and treatment outcomes in MDR tuberculosis-HIV-coinfected patients on ART to those in patients with MDR tuberculosis alone. This observational study enrolled culture-confirmed MDR tuberculosis patients with and without HIV in South Africa between 2011 and 2013. Participants received standardized MDR tuberculosis and HIV regimens and were followed monthly for treatment response, adverse events, and adherence. The primary outcome was survival. Among 206 participants, 150 were HIV infected, 131 (64%) were female, and the median age was 33 years (interquartile range [IQR], 26-41). Of the 191 participants with a final MDR tuberculosis outcome, 130 (73%) were cured or completed treatment, which did not differ by HIV status (P = .50). After 2 years, CD4 count increased a median of 140 cells/mm3 (P = .005), and 64% had an undetectable HIV viral load. HIV-infected and HIV-uninfected participants had high rates of survival (86% and 94%, respectively; P = .34). The strongest risk factor for mortality was having a CD4 count ≤100 cells/mm3 (adjusted hazards ratio, 15.6; 95% confidence interval, 4.4-55.6). Survival and treatment outcomes among MDR tuberculosis-HIV individuals receiving concurrent ART approached those of HIV-uninfected patients. The greatest risk of death was among HIV-infected individuals with CD4 counts ≤100 cells/mm3. These findings provide critical evidence to support concurrent treatment of MDR tuberculosis and HIV.

    Full Text Available INTRODUCTION: Vitamin D deficiency (VDD is a common condition among several populations in the world. VDD is associated with higher incidence of immune system disorders and faster progression of some infectious diseases. Vitamin D is known to be of physiological importance, it is considered an essential micronutrient for the bone health and plays a beneficial role in the prevention and/or treatment of a number of chronic diseases. Vitamin D has a complex action on the immune system. RESULTS: Evidence that vitamin D protects against tuberculosis has been supported by in vitro, epidemiological and some preliminary clinical studies. Vitamin D has a potential effect on HIV (human immunodeficiency virus and plays a crucial role in the defence against respiratory infections. CONCLUSIONS: Vitamin D supplementation could be a low-cost, practical method to protect groups of people with high incidence of those diseases. Public health education should stress the need for adequate dietary intake of vitamin D in those vulnerable groups.

    Alkaloid molecules can act, depending on a type of amine functionality present in alkalods, as either hydrogenacceptor or hydrogen-donor for hydrogen bonding that is critically important for the interaction (binding) between targets (enzymes, proteins and receptors) and drugs (ligands). Because of this unique property, alkaloid scaffolds are therefore present in several drugs and lead compounds. This review highlights alkaloid scaffolds in drugs, particularly those recently approved in 2012; it also covers the scaffolds in leads and drug candidates which are in clinical trials and preclinical pipeline. The review focuses on three therapeutic areas including treatments of cancer, tuberculosis, and tobacco cessation. Alkaloid scaffolds in drugs and leads are inspired by those of naturally occurring alkaloids, and these scaffolds include pyridine, piperidine, quinoline, quinolinone, quinazoline, isoquinoline, indole, indolinone, isoindole, isoxazole, imidazole, indazole, thiazole, pyrazole, oxazolidinone, oxadiazole, and benzazepine. In addition to medicinal chemistry aspects, natural products possessing an individual alkaloid scaffold, as well as the mechanism of action of drugs and leads, are also discussed in this review.

    Full Text Available Objective: The relationship between tuberculosis (TB treatment and alcohol use disorders over time is under-researched. The aim of this investigation was to study alcohol use and TB medication adherence and its predictors among TB patients over a period of 6 months. Methods: A longitudinal investigation was carried out with new TB and TB retreatment patients systematically selected from two hospitals and had screened positive for hazardous or harmful alcohol use in Sisaket Province in Thailand. Alcohol use disorders were measured with Alcohol Use Disorder Identification Test (AUDIT-C at baseline, 3 months and 6 months. Results: Of the 295 TB patients who were screened with AUDIT-C, 72 (24.4% tested positive for hazardous or harmful alcohol use. At 6 months, 72 TB patients had completed the follow- up. At the 6-month follow-up, hazardous or harmful drinking was reduced by 84.7%. Multivariate logistic regression analysis using generalised estimation equation modelling found that alcohol use significantly reduced over time, whereas there was no change in current tobacco use. Conclusion: The prevalence of alcohol use disorders significantly reduced over a period of 6 months.

    The introduction of new rapid diagnostic tools for tuberculosis (TB) and the promising TB drugs pipeline together with the development of a new World Health Organization Strategy post 2015 allows new discussions on how to direct TB control. The European Respiratory Society's European Forum for TB Innovation was created to stimulate discussion on how to best take advantage of old and new opportunities, and advances, to improve TB control and eventually progress towards the elimination of TB. While TB control is aimed at reducing the incidence of TB by early diagnosis and treatment of infectious cases of TB, TB elimination requires focus on sterilising the pool of latently infected individuals, from which future TB cases would be generated. This manuscript describes the three core components that are necessary to implement the elimination strategy fully. 1) Improve diagnosis of latent TB infected individuals. 2) Improve regimens to treat latent TB infection. 3) ensure public health commitment to make both 1) and 2) possible. Old and new evidence is critically described, focusing on the European commitment to reach elimination and on the innovative experiences and best practices available.

    Universal public finance (UPF)-government financing of an intervention irrespective of who is receiving it-for a health intervention entails consequences in multiple domains. First, UPF increases intervention uptake and hence the extent of consequent health gains. Second, UPF generates financial consequences including the crowding out of private expenditures. Finally, UPF provides insurance either by covering catastrophic expenditures, which would otherwise throw households into poverty or by preventing diseases that cause them. This paper develops a method-extended cost-effectiveness analysis (ECEA)-for evaluating the consequences of UPF in each of these domains. It then illustrates ECEA with an evaluation of UPF for tuberculosis treatment in India. Using plausible values for key parameters, our base case ECEA concludes that the health gains and insurance value of UPF would accrue primarily to the poor. Reductions in out-of-pocket expenditures are more uniformly distributed across income quintiles. A variant on our base case suggests that lowering costs of borrowing for the poor could potentially achieve some of the health gains of UPF, but at the cost of leaving the poor more deeply in debt. © 2014 The Authors.

    Full Text Available Background. The objectives were (i to evaluate the impact of acute pulmonary tuberculosis (PTB and anti-TB therapy on the relationship between AST, ALT, and GGT levels in absence of conditions related to hepatotoxicity; (ii to evaluate the rate and the time of alterations of AST, ALT, and GGT. Design and Methods. A prospective followup of 40 adults (21 males; mean age of 34.7±5.8 years with active PTB on initial phase and continuation phase anti-TB. Results. Only 3% (n=1 developed a transient and benign ADR at day 30 without interruption of anti-TB treatment. Within normal ranges, GGT decreased significantly from day 0 to day 60, while AST and ALT increased significantly and respectively. During day 0–day 60, there was a significant, negative, and independent association between GGT and AST. Conclusion. The initial two months led to significant improvement of oxidative stress. Values of oxidative markers in normal ranges might predict low rate of ADR.

    Setting: National Leprosy and Tuberculosis (TB) Control Programme, Liberia. Objectives: To assess TB case finding, including human immunodeficiency virus (HIV) associated interventions and treatment outcomes, before (January 2013–March 2014), during (April 2014–June 2015) and after (July–December 2015) the Ebola virus disease outbreak. Design: A cross-sectional study and retrospective cohort analysis of outcomes. Results: The mean quarterly numbers of individuals with presumptive TB and the proportion diagnosed as smear-positive were: pre-Ebola (n = 7032, 12%), Ebola (n = 6147, 10%) and post-Ebola (n = 6795, 8%). For all forms of TB, stratified by category and age group, there was a non-significant decrease in the number of cases from the pre-Ebola to the Ebola and post-Ebola periods. There were significant decreases in numbers of cases with smear-positive pulmonary TB (PTB) from the pre-Ebola period (n = 855), to the Ebola (n = 640, P < 0.001) and post-Ebola (n = 568, P < 0.001) periods. The proportions of patients tested for HIV, found to be HIV-positive and started on antiretroviral therapy decreased as follows: pre-Ebola (respectively 72%, 15% and 34%), Ebola (69%, 14% and 30%) and post-Ebola (68%, 12% and 26%). Treatment success rates among TB patients were: 80% pre-Ebola, 69% Ebola (P < 0.001) and 73% post-Ebola (P < 0.001). Loss to follow-up was the main contributing adverse outcome. Conclusion: The principal negative effects of Ebola were the significant decreases in diagnoses of smear-positive PTB, the declines in HIV testing and antiretroviral therapy uptake and poor treatment success. Ways to prevent these adverse effects from recurring in the event of another Ebola outbreak need to be found. PMID:28744441

    Pooled tuberculosis (TB) notifications from 13 European countries. To analyse the determinants of TB treatment success in different countries using individual data. We asked 18 European countries with both outcome data and individual TB records to code outcomes for cases notified in 2000 and/or 2001. Cases completing treatment regardless of bacteriological proof of cure were considered successful. Ten European Union countries and Iceland, Norway and Romania participated (72% response). Among 24 660 TB cases (Romania excluded), 'success' was reported in 69% (country range 60-88%), 9% (0-11%) died, 1% (0-5%) failed, 4% defaulted or transferred (2-15%) and 12% (0-23%) were 'unknown'. On logistic regression among cases with drug susceptibility results (n = 10 303), 'success' was associated with younger age (>74 years: reference; 55-74 years: OR = 2.0, 95%CI 1.8-2.4; 35-54 years: 3.0, 95%CI 2.6-3.5; 15-34 years: 3.7, 95%CI 3.2-4.4; <15 years: 4.4, 95%CI 2.9-6.7), female sex (1.4, 95%CI 1.3-1.6), and no polyresistance (9.2, 95%CI 6.8-12.4). The Netherlands (1.6, 95%CI 1.3-2.0) and Slovakia (1.8, 95%CI 1.4-2.2) had higher success than Estonia (reference: lowest percentage success), while Austria was lower (0.64, 95%CI 0.52-0.78). Preventing drug resistance, increasing adherence and improving care in the elderly should be priorities. Inter-country variations in treatment success suggest differences in the completeness of monitoring data and in the efficacy of national control programmes.

    Full Text Available The combination of rifapentine and moxifloxacin administered daily with other anti-tuberculosis drugs is highly active in mouse models of tuberculosis chemotherapy. The objective of this phase 2 clinical trial was to determine the bactericidal activity, safety, and tolerability of a regimen comprised of rifapentine, moxifloxacin, isoniazid, and pyrazinamide administered daily during the first 8 weeks of pulmonary tuberculosis treatment.Adults with sputum smear-positive pulmonary tuberculosis were randomized to receive either rifapentine (approximately 7.5 mg/kg plus moxifloxacin (investigational arm, or rifampin (approximately 10 mg/kg plus ethambutol (control daily for 8 weeks, along with isoniazid and pyrazinamide. The primary endpoint was sputum culture status at completion of 8 weeks of treatment.121 participants (56% of accrual target were enrolled. At completion of 8 weeks of treatment, negative cultures using Löwenstein-Jensen (LJ medium occurred in 47/60 (78% participants in the investigational arm vs. 43/51 (84%, p = 0.47 in the control arm; negative cultures using liquid medium occurred in 37/47 (79% in the investigational arm vs. 27/41 (66%, p = 0.23 in the control arm. Time to stable culture conversion was shorter for the investigational arm vs. the control arm using liquid culture medium (p = 0.03, but there was no difference using LJ medium. Median rifapentine area under the concentration-time curve (AUC0-24 was 313 mcg*h/mL, similar to recent studies of rifapentine dosed at 450-600 mg daily. Median moxifloxacin AUC0-24 was 28.0 mcg*h/mL, much lower than in trials where rifapentine was given only intermittently with moxifloxacin. The proportion of participants discontinuing assigned treatment for reasons other than microbiological ineligibility was higher in the investigational arm vs. the control arm (11/62 [18%] vs. 3/59 [5%], p = 0.04 although the proportions of grade 3 or higher adverse events were similar (5/62 [8%] in the

    Full Text Available AbstractLatent tuberculosis infection (LTBI and human immunodeficiency virus (HIV-coinfection are challenges in the control of tuberculosis transmission. We aimed to assess and summarize evidence available in the literature regarding the treatment of LTBI in both the general and HIV-positive population, in order to support decision making by the Brazilian Tuberculosis Control Program for LTBI chemoprophylaxis. We searched MEDLINE, Cochrane Library, Centre for Reviews and Dissemination, Embase, LILACS, SciELO, Trip database, National Guideline Clearinghouse, and the Brazilian Theses Repository to identify systematic reviews, randomized clinical trials, clinical guidelines, evidence-based synopses, reports of health technology assessment agencies, and theses that investigated rifapentine and isoniazid combination compared to isoniazid monotherapy. We assessed the quality of evidence from randomized clinical trials using the Jadad Scale and recommendations from other evidence sources using the Grading of Recommendations, Assessment, Development, and Evaluations approach. The available evidence suggests that there are no differences between rifapentine + isoniazid short-course treatment and the standard 6-month isoniazid therapy in reducing active tuberculosis incidence or death. Adherence was better with directly observed rifapentine therapy compared to self-administered isoniazid. The quality of evidence obtained was moderate, and on the basis of this evidence, rifapentine is recommended by one guideline. Available evidence assessment considering the perspective of higher adherence rates, lower costs, and local peculiarity context might support rifapentine use for LTBI in the general or HIV-positive populations. Since novel trials are ongoing, further studies should include patients on antiretroviral therapy.

    Full Text Available Abstract Background The role of interferon-γ release assay (IGRA in monitoring responses to anti-tuberculosis (TB treatment is not clear. We evaluated the results of the QuantiFERON-TB Gold In-tube (QFT-GIT assay over time during the anti-TB treatment of adults with no underlying disease. Methods We enrolled soldiers who were newly diagnosed with active TB and admitted to the central referral military hospital in South Korea between May 1, 2008 and September 30, 2009. For each participant, we preformed QFT-GIT assay before treatment (baseline and at 1, 3, and 6 months after initiating anti-TB medication. Results Of 67 eligible patients, 59 (88.1% completed the study protocol. All participants were males who were human immunodeficiency virus (HIV-negative and had no chronic diseases. Their median age was 21 years (range, 20-48. Initially, 57 (96.6% patients had positive QFT-GIT results, and 53 (89.8%, 42 (71.2%, and 39 (66.1% had positive QFT-GIT results at 1, 3, and 6 months, respectively. The IFN-γ level at baseline was 5.31 ± 5.34 IU/ml, and the levels at 1, 3, and 6 months were 3.95 ± 4.30, 1.82 ± 2.14, and 1.50 ± 2.12 IU/ml, respectively. All patients had clinical and radiologic improvements after treatment and were cured. A lower IFN-γ level, C-reactive protein ≥ 3 mg/dl, and the presence of fever (≥ 38.3°C at diagnosis were associated with negative reversion of the QFT-GIT assay. Conclusion Although the IFN-γ level measured by QFT-GIT assay decreased after successful anti-TB treatment in most participants, less than half of them exhibited QFT-GIT reversion. Thus, the reversion to negativity of the QFT-GIT assay may not be a good surrogate for treatment response in otherwise healthy young patients with TB.

    To evaluate the effect of rifampicin-based tuberculosis (TB) treatment on the pharmacokinetics of efavirenz/tenofovir/emtricitabine in a fixed-dose combination tablet, and vice versa, in Tanzanian TB-HIV-coinfected patients. This was a Phase II open-label multiple dose pharmacokinetic and safety study. This study was conducted in TB-HIV-coinfected Tanzanian patients who started TB treatment (rifampicin/isoniazid/pyrazinamide/ethambutol) at week 1 to week 8 and continued with rifampicin and isoniazid for another 16 weeks. Antiretroviral treatment (ART) of efavirenz/tenofovir/emtricitabine in a fixed-dose combination tablet was started at week 4 after initiation of TB treatment. A 24-h pharmacokinetic sampling curve was recorded at week 8 (with TB treatment) and week 28 (ART alone). For TB drugs, blood samples at 2 and 5 h post-dose were taken at week 3 (TB treatment alone) and week 8 (with ART). A total of 25 patients (56% male) completed the study; 21 had evaluable pharmacokinetic profiles. The area under the concentration-time curve 0-24 h post-dose of efavirenz, tenofovir and emtricitabine were slightly higher when these drugs were coadministered with TB drugs; geometric mean ratios (90% CI) were 1.08 (0.90, 1.30), 1.13 (0.93, 1.38) and 1.05 (0.85, 1.29), respectively. For TB drugs, equivalence was suggested for peak plasma concentrations when administered with and without efavirenz/tenofovir/emtricitabine. Adverse events were mostly mild and no serious adverse events or drug discontinuations were reported. Coadministration of efavirenz, tenofovir and emtricitabine with a standard first-line TB treatment regimen did not significantly alter the pharmacokinetic parameters of these drugs and was tolerated well by Tanzanian TB patients who are coinfected with HIV.

    Tuberculosis (TB) remains a major public health problem especially in low and middle-income countries. The current study was undertaken to estimate the incidence of the disease and describe its epidemiological characteristics in Iraqi Kurdistan. A retrospective study was carried out on cases registered in the directly observed treatment-short course (DOTS) centers in Sulaimaniyah province. Information was collected from the summary reports of all cases registered in 2010 and detailed information was obtained from 307 cases in the main center. During 2010, a total of 530 new and relapsed cases were registered in the DOTS centers amounting to an annual incidence of 31 per 100,000. Over 73% of cases were pulmonary TB and 45% of all cases had positive smear. Most common symptoms were cough (58%), sweating (49%) and fever (48). Almost 43% of patients were diagnosed by direct swab examination, 30% by biopsy and 23% through clinical and radiologic examination. In relation to outcome, 89% of patients were treated successfully, 7% died and 3% defaulted. Mortality rate was 8% in pulmonary infection and 4% in extrapulmonary infection. Old age (65 years and over) was significantly associated with higher odds of death compared to people aged 34 years and younger (OR 6.7, 95% CI 1.3-36.1, P=0.03). The incidence of TB is still high in the Iraqi Kurdistan. The DOTS has been successful in treating the majority of cases but there are areas needing improvement especially record-keeping and patient follow-up during and after treatment.

    To assess the degree of implementation of the Directly Observed Treatment, Short-course - DOTS for tuberculosis (TB) in a large city. Assessment of the implementation of the logic model, whose new cases of infectious pulmonary TB were recruited from specialized clinics and followed-up in basic health units. The judgment matrix covering the five components of the DOTS strategy were used. The result of the logic model indicates DOTS was partially implemented. In external, organizational and implementation contexts, the DOTS strategy was partially implemented; and, the effectiveness was not implemented. The partial implementation of the DOTS strategy in the city of Manaus did not reflect in TB control compliance, leading to low effectiveness of the program. Avaliar o grau de implantação da estratégia de tratamento diretamente observado (Directly Observed Treatment, Short-course - DOTS) para tuberculose (TB) em um município de grande porte. Avaliação de implantação por meio de modelo lógico, cujos casos novos de TB pulmonar bacilífera foram recrutados em ambulatórios especializados e acompanhados nas unidades básicas de saúde. Utilizou-se matriz de julgamento que abrange os cinco componentes da estratégia DOTS. O resultado do modelo lógico indica DOTS implantada parcialmente. Nos contextos externo, organizacional e de implantação, a estratégia DOTS está implantada parcialmente; e, na efetividade não está implantada. A implantação parcial da estratégia DOTS, na cidade de Manaus, reflete na não conformidade do controle da TB, levando à baixa efetividade do programa.

    Full Text Available Cross-sectional studies reveal an association between tuberculosis (TB and chronic airflow obstruction, but cannot adequately address confounding. We hypothesised that treated pulmonary TB is an independent risk factor for chronic airflow obstruction. The Pulmones Post TB cohort study enrolled participants from Lima, Peru, aged 10–70 years with a history of drug-susceptible (DS- or multidrug-resistant (MDR-TB who had completed treatment and were clinically cured. Unexposed participants without TB were randomly selected from the same districts. We assessed respiratory symptoms, relevant environmental exposures, and spirometric lung function pre- and post-bronchodilator. In total, 144 participants with DS-TB, 33 with MDR-TB and 161 unexposed participants were fully evaluated. Compared with unexposed participants, MDR-TB patients had lower lung volumes (adjusted mean difference in forced vital capacity −370 mL, 95% CI −644– −97 and post-bronchodilator airflow obstruction (adjusted OR 4.89, 95% CI 1.27–18.78. Participants who had recovered from DS-TB did not have lower lung volumes than unexposed participants, but were more likely to have a reduced forced expiratory volume in 1 s/forced vital capacity ratio <0.70 (adjusted OR 2.47, 95% CI 1.01–6.03. Individuals successfully treated for TB may experience long-lasting sequelae. Interventions facilitating earlier TB treatment and management of chronic respiratory disease should be explored.

    Existing trials of adjunctive vitamin D in the treatment of pulmonary tuberculosis (PTB) are variously limited by small sample sizes, inadequate dosing regimens, and high baseline vitamin D status among participants. Comprehensive analyses of the effects of genetic variation in the vitamin D pathway on response to vitamin D supplementation are lacking. To determine the effect of high-dose vitamin D 3 on response to antimicrobial therapy for PTB and to evaluate the influence of single-nucleotide polymorphisms (SNPs) in vitamin D pathway genes on response to adjunctive vitamin D 3 . We conducted a clinical trial in 390 adults with PTB in Ulaanbaatar, Mongolia, who were randomized to receive four biweekly doses of 3.5 mg (140,000 IU) vitamin D 3 (n = 190) or placebo (n = 200) during intensive-phase antituberculosis treatment. The intervention elevated 8-week serum 25-hydroxyvitamin D concentrations (154.5 nmol/L vs. 15.2 nmol/L in active vs. placebo arms, respectively; 95% confidence interval for difference, 125.9-154.7 nmol/L; P vitamin D 3 accelerated sputum culture conversion in patients with one or more minor alleles for SNPs in genes encoding the vitamin D receptor (rs4334089, rs11568820) and 25-hydroxyvitamin D 1α-hydroxylase (CYP27B1: rs4646536) (adjusted hazard ratio ≥ 1.47; P for interaction ≤ 0.02). Vitamin D 3 did not influence time to sputum culture conversion in the study population overall. Effects of the intervention were modified by SNPs in VDR and CYP27B1.

    2017-01-01

    Full Text Available It has been reported that tuberculosis (TB worsens after cessation of tumor necrosis factor-α inhibitors and starting anti-TB treatment. Little is known about the immunological pathogenesis of this paradoxical response (PR. We report the first case of a TB patient in whom PR occurred concurrently with elevation of circulating tumor necrosis factor-α (TNFα levels. A 75-year-old woman, who had been treated with adalimumab for SAPHO syndrome, developed disseminated TB. Soon after administration of anti-TB treatment (isoniazid, rifampicin, pyrazinamide, and ethambutol, and after discontinuation of adalimumab, a PR occurred. Serial testing of serum cytokine levels revealed a marked increase in TNFα, and a decline in interferon-γ levels. Despite intensive treatment with antibiotics, prednisolone, noradrenaline, and mechanical ventilation, acute respiratory distress syndrome developed and she died. Thus, overproduction of TNFα after cessation of TNFα inhibitors may partially account for the pathogenesis of a PR. This supports preventative or therapeutic reinitiation of TNFα inhibitors when PR occurs. Serial monitoring of circulating inflammatory cytokine levels could lead to earlier identification of a PR.

    To describe the epidemiological situation and the incidence of tuberculosis and to investigate the factors associated with treatment default in the Amazonian municipalities located in the northern Brazilian international border. This retrospective study employed sociodemographic, clinical, and epidemiological tuberculosis data recorded in the Brazilian Notifiable Diseases Information System (SINAN) between 2001 and 2010. Logistic regression was used to identify factors associated with treatment default. Tuberculosis affected mostly indigenous peoples (51.9%), males (57.9%), and people aged 25-44 years (31.4%). The predominant clinical presentation was pulmonary (89.7%), yet in 24.5% of the cases the patients did not undergo sputum smear microscopy, and only half received supervised treatment. In 70.0% of the cases notified, patients were discharged as cured. Treatment default was recorded in 10.0% of the patients. Of all deaths, 4.1% were by tuberculosis and other causes, and 1.7% by multidrug-resistant tuberculosis. The average incidence by race/color was greater among indigenous peoples, ranging from 202.3/100 000 in 2001 to 65.6/100 000 in 2010. Treatment default was associated with failure to perform the follow-up smear at the second, fourth, and sixth months (OR = 11.9, 95%CI: 7.4-19.0); with resuming treatment after default (OR = 3.0, 95%CI: 1.5-5.9); and with living in specific subregions, particularly the Alto Solimões region (OR = 6.7, 95%CI: 4.6-9.8). The present results show a high incidence of tuberculosis in the Amazon portion of the northern Brazilian international border, especially among indigenous peoples. Considering the socio-cultural specificities of these populations and the poor tuberculosis control in this area, the authors of the study conclude that the integration of different national health systems is both necessary and urgent.

    Background Despite its benefit for treating active tuberculosis, directly observed therapy (DOT) for latent tuberculosis infection (LTBI) has been largely understudied among challenging inner city populations. Methods Utilizing questionnaire data from a comprehensive mobile healthcare clinic in New Haven, CT from 2003 to July 2011, a total of 2523 completed tuberculin skin tests (TST’s) resulted in 357 new LTBIs. Multivariate logistic regression correlated covariates of the two outcomes 1) initiation of isoniazid preventative therapy (IPT) and 2) completion of 9-months IPT. Results Of 357 new LTBIs, 86.3% (n=308) completed screening CXRs: 90.3% (n=278) were normal and 0.3% (n=1) with active tuberculosis. Of those completing CXR screening, 44.0% (n=135) agreed to IPT: 69.6% (n=94) selected DOT, and 30.4% (n=41) selected SAT. Initiating IPT was correlated with undocumented status (AOR=3.43; pmodels for LTBI treatment resulted in similar outcomes, yet outcomes were hampered by differential measurement bias between DOT and SAT participants.

    Backgrounds Patients who develop an active tuberculosis infection during tumor necrosis factor (TNF) inhibitor treatment typically discontinue TNF inhibitor and receive standard anti-tuberculosis treatment. However, there is currently insufficient information on patient outcomes following resumption of TNF inhibitor treatment during ongoing anti- tuberculosis treatment. Our study was designed to investigate the safety of resuming TNF inhibitors in ankylosing spondylitis (AS) patients who developed tuberculosis as a complication of the use of TNF inhibitors. Methods Through the nationwide registry of the Korean Society of Spondyloarthritis Research, 3929 AS patients who were prescribed TNF inhibitors were recruited between June 2003 and June 2014 at fourteen referral hospitals. Clinical information was analyzed about the patients who experienced tuberculosis after exposure to TNF inhibitors. The clinical features of resumers and non-resumers of TNF inhibitors were compared and the outcomes of tuberculosis were surveyed individually. Findings Fifty-six AS patients were treated for tuberculosis associated with TNF inhibitors. Among them, 23 patients resumed TNF inhibitors, and these patients were found to be exposed to TNF inhibitors for a longer period of time and experienced more frequent disease flare-up after discontinuation of TNF inhibitors compared with those who did not resume. Fifteen patients resumed TNF inhibitors during anti-tuberculosis treatment (early resumers) and 8 after completion of anti-tuberculosis treatment (late resumers). Median time to resuming TNF inhibitor from tuberculosis was 3.3 and 9.0 months in the early and late resumers, respectively. Tuberculosis was treated successfully in all resumers and did not relapse in any of them during follow-up (median 33.8 [IQR; 20.8–66.7] months). Conclusions Instances of tuberculosis were treated successfully in our AS patients, even when given concomitantly with TNF inhibitors. We suggest that early

    Tuberculosis (TB) treatment is long and complex, typically involving a combination of drugs taken for 6 months. Improved drug regimens to shorten and simplify treatment are urgently required, however a major challenge to TB drug development is the lack of predictive pre-clinical tools. To address this deficiency, we have adopted a new high-content imaging-based approach capable of defining the killing kinetics of first line anti-TB drugs against intracellular Mycobacterium tuberculosis (Mtb) residing inside macrophages. Through use of this pharmacokinetic-pharmacodynamic (PK-PD) approach we demonstrate that the killing dynamics of the intracellular Mtb sub-population is critical to predicting clinical TB treatment duration. Integrated modelling of intracellular Mtb killing alongside conventional extracellular Mtb killing data, generates the biphasic responses typical of those described clinically. Our model supports the hypothesis that the use of higher doses of rifampicin (35 mg/kg) will significantly reduce treatment duration. Our described PK-PD approach offers a much needed decision making tool for the identification and prioritisation of new therapies which have the potential to reduce TB treatment duration.

    Stigma, considered a social disease, is more apparent in developing societies which are driven by various social affairs, and influences adherence to treatment. The aim of the present study was to examine levels of social stigma related to tuberculosis (TB) in sociodemographic context and identify the effects of sociodemographic factors on stigma. The study sample consisted of 372 TB patients. Data were collected using stratified sampling with simple random sampling techniques. T tests, chi-square tests, and binary logistic regression analysis were performed to examine correlations between stigma and sociodemographic variables. Approximately 85.9% of patients had experienced stigma. The most frequent indicator of the stigma experienced by patients involved problems taking part in social programs (79.5%). Mean levels of stigma were significantly higher in women (55.5%), illiterate individuals (60.8%), and villagers (60.8%) relative to those of other groups. Chi-square tests revealed that education, monthly family income, and type of patient (pulmonary and extrapulmonary) were significantly associated with stigma. Binary logistic regression analysis demonstrated that stigma was influenced by sex, education, and type of patient. Stigma is one of the most important barriers to treatment adherence. Therefore, in interventions that aim to reduce stigma, strong collaboration between various institutions is essential.

    Full Text Available Commencement of antiretroviral treatment (ART in severely immunosuppressed HIV-infected persons is associated with unmasking of subclinical disease. The subset of patients that are diagnosed with tuberculosis (TB disease while on ART have been classified as ART-associated TB. Few studies have reported the incidence of ART-associated TB and unmasking TB-IRIS according to the International Network for the Study of HIV-Associated IRIS (INSHI consensus definition. To determine the incidence and predictors of ART-associated TB, we screened 219 patients commencing ART at the Infectious Diseases Clinic in Kampala, Uganda for TB by symptoms, sputum microscopy, and chest X-rays and followed them for one year. Fourteen (6.4% patients were diagnosed with TB during followup. Eight (3.8% patients had ART-associated TB (incidence rate of 4.3 per 100 person years; of these, three patients fulfilled INSHI criteria for unmasking TB-associated IRIS (incidence rate of 1.6 per 100 person years. A body mass index of less than 18.5 kg/m2 BMI (HR 5.85 95% CI 1.24–27.46, P=.025 and a C-reactive protein greater than 5 mg/L (HR 8.23 95% CI 1.36–38.33, P=.020 were risk factors for ART-associated TB at multivariate analysis. In conclusion, with systematic TB screening (including culture and chest X-ray, the incidence of ART-associated TB is relatively low in settings with high HIV and TB prevalence.

    Treatment outcomes serve as proxy measures of the quality of tuberculosis treatment provided by the health care system, and it is essential to evaluate the effectiveness of Directly Observed Therapy-Short course program in controlling the disease, and reducing treatment failure, default and death. Hence, we evaluated tuberculosis treatment success rate, its trends and predictors of unsuccessful treatment outcome in Ethiopian Somali region where 85% of its population is pastoralist. A retrospective review of 5 years data (September 2009 to August 2014) was conducted to evaluate the treatment outcome of 1378 randomly selected tuberculosis patients treated in Kharamara, Dege-habour and Gode hospitals. We extracted data on socio-demographics, HIV Sero-status, tuberculosis type, treatment outcome and year using clinical chart abstraction sheet. Tuberculosis treatment outcomes were categorized into successful (cured and/or completed) and unsuccessful (died/failed/default) according to the national tuberculosis guideline. Data was entered using EpiData 3.1 and analyzed using SPSS 20. Chi-square (χ 2 ) test and logistic regression model were used to reveal the predictors of unsuccessful treatment outcome at P ≤ 0.05 significance level. The majority of participants was male (59.1%), pulmonary smear negative (49.2%) and new cases (90.6%). The median age was 26 years [IQR: 18-40] and HIV co-infection rate was 4.6%. The overall treatment success rate was 86.8% [95%CI: 84.9% - 88.5%]; however, 4.8%, 7.6% and 0.7% of patients died, defaulted and failed to cure respectively. It fluctuated across the years and ranged from 76.9% to 94% [p tuberculosis types and HIV status (P > 0.05). This study revealed that the overall tuberculosis treatment success rate has realized the global target for 2011-2015. However, it does not guarantee its continuity as adverse treatment outcomes might unpredictably occur anytime and anywhere. Therefore, continual effort to effectively

    Tuberculosis (TB) remains a major global health problem and is the leading killer due to a single infectious disease. Mobile health (mHealth)-based tools such as smartphone apps have been suggested as tools to support TB control efforts (eg, identification, contact tracing, case management including patient support). The purpose of this review was to identify and assess the functionalities of mobile apps focused on prevention and treatment of TB. We searched 3 online mobile app stores. Apps were included if they were focused on TB and were in English, Spanish, or Portuguese. For each included app, 11 functionalities were assessed (eg, inform, instruct, record), and searches were conducted to identify peer-review publications of rigorous testing of the available apps. A total of 1332 potentially relevant apps were identified, with 24 meeting our inclusion criteria. All of the apps were free to download, but 7 required login and password and were developed for specific clinics, regional sites, or research studies. Targeted users were mainly clinicians (n=17); few (n=4) apps were patient focused. Most apps (n=17) had 4 or fewer functions out of 11 (range 1-6). The most common functionalities were inform and record (n=15). Although a number of apps were identified with various functionalities to support TB efforts, some had issues such as incorrect spelling and grammar, inconsistent responses to data entry, problems with crashing, or links to features that had no data. Of more concern, some apps provided potentially harmful information to patients, such as links to natural remedies for TB and natural healers. One-third of the apps (8/24) had not been updated for more than a year and may no longer be supported. Peer-reviewed publications were identified for only two of the included apps. In the gray literature (not found in the app stores), three TB-related apps were identified as in progress, being launched, or tested. Apps identified for TB prevention and treatment

    Around 0.4 million cases of multidrug-resistant tuberculosis (MDR-TB) occur each year. Only a small fraction of these cases are treated according to international guidelines. Evidence relevant to decisions about whether to scale-up treatment for MDR-TB includes cost and cost-effectiveness data. Up to 2010, no systematic review of this evidence has been available. Our objective was to conduct a systematic review of the cost and cost effectiveness of treatment for MDR-TB and synthesize the available data. We searched for papers published or prepared for publication in peer-review journals and grey literature using search terms in five languages: English, French, Portuguese, Russian and Spanish. From an initial set of 420 studies, four were included, from Peru, the Philippines, Estonia and Tomsk Oblast in the Russian Federation. Results on costs, effectiveness and cost effectiveness were extracted. Assessment of the quality of each economic evaluation was guided by two existing checklists around which there is broad consensus. Costs were adjusted to a common year of value (2005) to remove distortions caused by inflation, and calculated in two common currencies: $US and international dollars (I$), to standardize for purchasing power parity. Data from the four identified studies were then synthesized using probabilistic sensitivity analysis, to appraise the likely cost and cost effectiveness of MDR-TB treatment in other settings, relative to WHO benchmarks for assessing whether or not an intervention is cost effective. Best estimates are provided as means, with 5th and 95th percentiles of the distributions. The cost per patient for MDR-TB treatment in Estonia, Peru, the Philippines and Tomsk was $US10 880, $US2423, $US3613 and $US14 657, respectively. Best estimates of the cost per disability-adjusted life-year (DALY) averted were $US598 (I$960), $US163 (I$291), $US143 (I$255) and $US745 (I$1059), respectively. The main influences on costs were (i) the model of care

    During the treatment phase of active pulmonary tuberculosis (PTB), respiratory function impairment is usually restrictive. This may become obstructive, as a PTB-associated airflow obstruction (AFO) or as a later manifestation of underlying COPD. The aim of the study was to examine the potential causes and risks for AFO development in PTB by exploring the aspects of spirometry limitations and clinical implications for the underlying COPD detection, taking into account various confounding factors. Prospective, nest case-control study on 40 new cases of PTB with initial restrictive respiratory function impairment, diagnosed and treated according to the directly observed treatment short course (DOTS) strategy. From all observed patients, 37.5% of them developed AFO upon the completion of PTB treatment, with significantly increased average of forced vital capacity (%) (Ppulmonary tuberculosis lesions (OR 1.01-1.05 for 95% CI; P=0.02) and sputum conversion rate on culture (OR 1.02-1.68 for 95% CI; P=0.04) as the most significant predictors for the risk of AFO development. AFO upon PTB treatment is a common manifestation of underlying COPD, which mostly occurs later, during the reparative processes in active PTB, even in the absence of major risk factors, such as cigarette smoking and biomass fuel dust exposure. Initial spirometry testing in patients with active PTB is not a sufficient and accurate approach in the detection of underlying COPD, which may lead to their further potential health deterioration.

    Melissa Ehman

    Full Text Available INTRODUCTION: Tuberculosis (TB requires at least six months of multidrug treatment and necessitates monitoring for response to treatment. Historically, public health departments (HDs have cared for most TB patients in the United States. The Affordable Care Act (ACA provides coverage for uninsured persons and may increase the proportion of TB patients cared for by private medical providers and other providers outside HDs (PMPs. We sought to determine whether there were differences in care provided by HDs and PMPs to inform public health planning under the ACA. METHODS: We conducted a retrospective, cross-sectional analysis of California TB registry data. We included adult TB patients with culture-positive, pulmonary TB reported in California during 2007-2011. We examined trends, described case characteristics, and created multivariate models measuring two standards of TB care in PMP- and HD-managed patients: documented culture conversion within 60 days, and use of directly observed therapy (DOT. RESULTS: The proportion of PMP-managed TB patients increased during 2007-2011 (p = 0.002. On univariable analysis (N = 4,606, older age, white, black or Asian/Pacific Islander race, and birth in the United States were significantly associated with PMP care (p<0.05. Younger age, Hispanic ethnicity, homelessness, drug or alcohol use, and cavitary and/or smear-positive TB disease, were associated with HD care. Multivariable analysis showed PMP care was associated with lack of documented culture conversion (adjusted relative risk [aRR] = 1.37, confidence interval [CI] 1.25-1.51 and lack of DOT (aRR = 8.56, CI 6.59-11.1. CONCLUSION: While HDs cared for TB cases with more social and clinical complexities, patients under PMP care were less likely to receive DOT and have documented culture conversion. This indicates a need for close collaboration between PMPs and HDs to ensure that optimal care is provided to all TB patients and TB transmission is

    Full Text Available Abstract Background Evidence exists pointing out how non-adherence to treatment remains a major hurdle to efficient tuberculosis control in developing countries. Many tuberculosis (Tb patients do not complete their six-month course of anti-tuberculosis medications and are not aware of the importance of sputum re-examinations, thereby putting themselves at risk of developing multidrug-resistant and extensively drug-resistant forms of tuberculosis and relapse. However, there is a dearth of publications about non-adherence towards anti-Tb medication in these settings. We assessed the prevalence of and associated factors for anti-Tb treatment non-adherence in public health care facilities of South Ethiopia. Methods This was a cross-sectional survey using both quantitative and qualitative methods. The quantitative study was conducted among 261 Tb patients from 17 health centers and one general hospital. The qualitative aspect included an in-depth interview of 14 key informants. For quantitative data, the analysis of descriptive statistics, bivariate and multiple logistic regression was carried out, while thematic framework analysis was applied for the qualitative data. Results The prevalence of non-adherence towards anti-Tb treatment was 24.5%. Multiple logistic regression analysis demonstrated that poor knowledge towards tuberculosis and its treatment (AOR = 4.6, 95%CI: 1.4-15.6, cost of medication other than Tb (AOR = 4.7, 95%CI: 1.7-13.4, having of health information at every visit (AOR = 3, 95% CI: 1.1-8.4 and distance of DOTS center from individual home (AOR = 5.7, 95%CI: 1.9-16.8 showed statistically significant association with non-adherence towards anti- tuberculosis treatment. Qualitative study also revealed that distance, lack of awareness about importance of treatment completion and cost of transportation were the major barriers for adherence. Conclusions A quarter of Tb patients interrupted their treatment due to knowledge

    Objective: To investigate clinical effect of bronchial artery embolization (BAE) in treating massive hemoptysis due to pulmonary tuberculosis and to analyze the causes of recurrence in order to improve the therapeutic results. Methods: A total of 39 cases of patients with recurrent massive hemoptysis due to pulmonary tuberculosis, who were encountered during the period from Oct. 2007 to Sep. 2010, were enrolled in this study. The lesions included infiltrative pulmonary tuberculosis (n= 28) and chronic fibrocavitary pulmonary tuberculosis (n= 11). BAE with polyvinyl alcohol (PVA) particles only was performed in 14 cases (group A), while BAE with both PVA particles and coils was carried out in 25 cases (group B). All the patients were followed up for 12 - 48 months. The results were compared between the two groups. Results: Immediate hemostasis was obtained in 36 cases (92.3%), the clinical result was excellent in 3 cases. The complete cure or excellent result with single embolization procedure was achieved in 30 cases (76.9%). Recurrence was seen in 9 cases (23.1%). The difference in the recurrence rate between group A (42.9%) and group B (12.0%) was statistically significant (P < 0.05). The relapsing rate of patients with chronic fibrocavitary pulmonary tuberculosis was significantly higher than that of patients with infiltrative pulmonary tuberculosis (45.5% vs. 14.3%, P < 0.05). Conclusion: BAE has an instant effect of hemostasis and satisfactory clinical result. Nowadays BAE has already become the treatment of first choice for hemoptysis caused by pulmonary tuberculosis. The dual embolization technique with the combination use of PVA particles and coils can effectively reduce the recurrence of' pulmonary tuberculosis hemoptysis. (authors)

    Full Text Available The objective of this study was to evaluate the impact of the tuberculosis (TB mobile teams on treatment outcomes in Riyadh Region by comparing patients who received treatment under mobile teams and those who did not, from 2013 to 2015. This was a retrospective descriptive study using National TB Control and Prevention Program data from 2013 to 2015 from Riyadh, Kingdom of Saudi Arabia. Descriptive analyses were used to summarize characteristics of TB case-patients served by mobile teams and those who were not served. The χ2 test measured the significant differences between mobile-served and non-mobile-served case-patients. Exposure was whether or not the TB case-patient was under the care of the mobile team; the outcome of interest was whether or not treatment was successful, defined as treatment completed and cured. We found that the ratio of treatment success among mobile team case-patients was 1.28 greater than among those not served by mobile teams. The χ2 test showed a statistically significant finding (probability ratio = 1.28; 95% confidence interval = 1.21–1.35, p < 0.01. Mobile teams increased the treatment success rate to 92%, compared to 71.77% among those not served by mobile teams. This study shows that community mobilization of mobile teams is an effective strategy to enhance TB treatment, reduced mortality and loss to follow-up and improve TB treatment outcomes.

    In 2010, the World Health Organization revised the recommendations for the treatment of tuberculosis (TB) in children. The major revision was to increase isoniazid, rifampicin and pyrazinamide dosages according to body weight in children. The recommendations for higher dosages are based on consistent evidence from 1) pharmacokinetic studies suggesting that young children require higher dosages than adolescents and adults to achieve desired serum concentrations; and 2) observational studies reporting that the higher dosages would not be associated with increased risk of toxicity in children. However, national tuberculosis programmes faced unforeseen challenges in implementing the revised recommendations. The main difficulty was to adapt the revised dosages for the treatment of children with drug-susceptible TB using available fixed-dose combinations (FDCs). A more suitable FDC for the intensive and continuation phases of treatment has now been developed for planned implementation in 2015. This paper explains the background and rationale for the development of a new FDC tablet for children with drug-susceptible TB.

  16. Towards an empowerment approach in tuberculosis treatment in Cape Town, South Africa: a qualitative analysis of programmatic change

    Full Text Available Background: Tuberculosis rates in the world remain high, especially in low- and middle-income countries. International tuberculosis (TB policy generally recommends the use of directly observed therapy (DOT to ensure treatment adherence. Objective: This article examines a change in TB treatment support that occurred in 2005 in South Africa, from DOT to the enhanced TB adherence programme (ETA. Design: Seven key individuals representing academics, policy makers and service providers involved in the development of the ETA programme or knowledgeable about the issue were purposively sampled and interviewed, and participant observation was conducted at ETA programme steering group meetings. Qualitative content analysis was used to analyse the data, drawing on the Kingdon model of agenda setting. This model suggests that three independent streams – problem, policy and politics – come together at a certain point, often facilitated by policy entrepreneurs, to provide an opportunity for an issue to enter the policy agenda. Results: The results suggest the empowerment-oriented programme emerged through the presence of policy entrepreneurs with access to resources. Policy entrepreneurs were influenced by a number of simultaneously occurring challenges including problems within the existing programme; a perceived mismatch between patient needs and the existing TB treatment model; and the TB-HIV co-epidemic. Policy entrepreneurs saw the ART approach as a possible solution to these challenges. Conclusions: The Kingdon model contributed to describing the process of policy change. Research evidence seemed to influence this change diffusely, through the interaction of policy entrepreneurs and academics.

    Thailand has been greatly affected by the tuberculosis (TB) and HIV syndemic. This study aimed to determine treatment outcomes among HIV/TB co-infected patients. A retrospective cohort study was conducted at Chiang Mai University Hospital from 1 January 2000 to 31 December 2009. Of 171 patients, 100 patients were male (58.5%) and the mean age was 36.8 ± 8.0 years. Seventy-two patients (42.1%) had pulmonary tuberculosis. Median CD4+ count before TB treatment was 69 cells/mm(3) (interquartile range [IQR] 33, 151). The overall mortality was 3.5% (6 patients). Immune reconstitution inflammatory syndrome (IRIS) occurred in eight patients (6.0%). Disseminated TB infections increased risk of death (odds ratio [OR] = 2.55, 95% confidence interval [CI] 1.25, 5.18) and IRIS (OR = 9.16, 95% CI 1.67, 50.07). Initiating combination antiretroviral therapy (cART) within two months after TB treatment increased risk of IRIS (OR = 6.57, 95% CI 1.61-26.86) and physicians caring for HIV/TB co-infected patients should be aware of this condition.

    The aminoglycosides and cyclic polypeptides are essential drugs in the treatment of multidrug-resistant tuberculosis, underscoring the need for accurate and reproducible drug susceptibility testing (DST). The epidemiological cutoff value (ECOFF) separating wild-type susceptible strains from non-wild-type strains is an important but rarely used tool for indicating susceptibility breakpoints against Mycobacterium tuberculosis. In this study, we established wild-type MIC distributions on Middlebrook 7H10 medium for amikacin, kanamycin, streptomycin, capreomycin, and viomycin using 90 consecutive clinical isolates and 21 resistant strains. Overall, the MIC variation between and within runs did not exceed +/-1 MIC dilution step, and validation of MIC values in Bactec 960 MGIT demonstrated good agreement. Tentative ECOFFs defining the wild type were established for all investigated drugs, including amikacin and viomycin, which currently lack susceptibility breakpoints for 7H10. Five out of seven amikacin- and kanamycin-resistant isolates were classified as susceptible to capreomycin according to the current critical concentration (10 mg/liter) but were non-wild type according to the ECOFF (4 mg/liter), suggesting that the critical concentration may be too high. All amikacin- and kanamycin-resistant isolates were clearly below the ECOFF for viomycin, and two of them were below the ECOFF for streptomycin, indicating that these two drugs may be considered for treatment of amikacin-resistant strains. Pharmacodynamic indices (peak serum concentration [Cmax]/MIC) were more favorable for amikacin and viomycin compared to kanamycin and capreomycin. In conclusion, our data emphasize the importance of establishing wild-type MIC distributions for improving the quality of drug susceptibility testing against Mycobacterium tuberculosis.

SETTINGS AND DESIGN: Prospective study design. MATERIALS AND METHODS: Fifty infertile women with female genital tuberculosis (FGTB without tubo-ovarian masses diagnosed by positive acid-fast bacilli culture or epithelioid granuloma on endometrial aspirate or positive polymerase chain reaction with positive findings on laparoscopy or hysteroscopy were recruited. The ovarian function tests were performed on day 2/3 as follicle-stimulating hormone (FSH levels and anti-Mullerian hormone (AMH levels. Ovarian dimensions (length, width, and depth were measured using a transvaginal ultrasound. Mean antral follicle count (AFC and ovarian stromal blood flow (peak systolic velocity [PSV], pulsatility index (PI, and resistive index [RI] were measured using a transvaginal ultrasound. All women were started on ATT for 6 months by directly observed treatment strategy. After completion of ATT, all the parameters were repeated. RESULTS: There was a significant increase in AMH (2.68 ± 0.97 ng/ml to 2.8 ± 1.03 ng/ml pre- to post-ATT, nonsignificant increase in FSH (7.16 ± 2.34 mIU/ml to 7.26 ± 2.33 mIU/ml post-ATT, significant increase in mean AFC (7.40 ± 2.12-8.14 ± 2.17, PSV in the right ovary (6.015-6.11 cm/s and left ovary (6.05-6.08 cm/s, PI in the right ovary (0.935-0.951 cm/s and left ovary (0.936-0.957 cm/s, and RI in the right ovary (0.62 ± 0.01-0.79 ± 0.02 and left ovary (0.65 ± 0.02-0.84 ± 0.01 with ATT. There was no significant change in mean ovarian dimensions (ovarian length, breadth, and width and summed ovarian volume with ATT. On laparoscopy, tubercles were seen in 27 (54% women. Caseous nodules and encysted ascites were seen in 8% cases each. CONCLUSION: ATT improves the ovarian function (AMH and AFC and ovarian blood flow in women with FGTB.

    Full Text Available Background. In TB control, poor treatment adherence is a major cause of relapse and drug resistance. Nurses have a critical role in supporting patients in TB treatment process. Yet, very little research has been done to inform policymakers and practitioners on nurses’ experiences of treatment adherence among patients with TB. Aim. To describe nurses’ experiences of supporting treatment adherence among patients with tuberculosis in Burundi. Method. The study adopted qualitative approach with a descriptive design. A purposive sampling was performed. Eight nurses were selected from two TB treatment centers in Burundi. Content analysis was used to analyze the data. Result. According to the nurses, most patients complete their treatment. Educating patients, providing the medication, observing and following up treatment, and communicating with the patients were the key tasks by nurses to support adherence. Causes for interruption were medication-related difficulties, poverty, and patients’ indiscipline. Treatment adherence could also be affected by patients’ and nurses’ feelings. Providing transportation and meals could enhance treatment compliance. Conclusion. Nurses are critical resources to TB treatment success. In a poverty stricken setting, nurses’ work could be facilitated and adherence further could be enhanced if socioeconomic problems (transportation and nutritional support were alleviated.

    To determine whether there are demographic, clinical and radiological differences among patients with pulmonary tuberculosis (TB) and patients with TB and type 2 diabetes mellitus (DM2 + TB). Observational retrospective cohort study. We compared the clinical characteristics of patients according to sex, age, time to sputum conversion to negative, presence of cavitation and the cure rate, duration of treatment and the proportion of change of treatment regimen, in patients with and without DM2 served by the Tuberculosis Control Program from 2010 to 2012 in the Rebagliati Healthcare Network of Lima, Peru. 31 patients with TB+DM2 and 144 patients with TB were included. Differences (p<0.05) in the diagnostic method, the average of symptoms and the resistance pattern of TB among patients with and without DM2 were found. The presence of cavitation was more frequent in patients with TB + DM2. Having TB + DM2 delayed the time to sputum smear conversion to negative (RRa 4.16, 95% CI: 1.1-1.6) in the adjusted Cox regression analysis. There are differences in demographic, clinical and radiological characteristics in TB patients with and without DM2.The time to sputum conversion to negative is greater in patients with DM2.

    Tuberculosis (TB) is the deadliest infectious disease globally, with 10.4 million people infected and more than 1.8 million deaths in 2015. TB is a preventable, treatable, and curable disease, yet there are numerous barriers to initiating treatment. These barriers to treatment are exacerbated in low-resource settings and may be compounded by factors related to childhood. Timely initiation of tuberculosis (TB) treatment is critical to reducing disease transmission and improving patient outcomes. The aim of this paper is to describe patient- and system-level barriers to TB treatment initiation specifically for children and youth in sub-Saharan Africa through systematic review of the literature. This review was conducted in October 2015 in accordance with preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Six databases were searched to identify studies where primary or secondary objectives were related to barriers to TB treatment initiation and which included children or youth 0-24 years of age. A total of 1490 manuscripts met screening criteria; 152 met criteria for full-text review and 47 for analysis. Patient-level barriers included limited knowledge, attitudes and beliefs regarding TB, and economic burdens. System-level barriers included centralization of services, health system delays, and geographical access to healthcare. Of the 47 studies included, 7 evaluated cost, 19 health-seeking behaviors, and 29 health system infrastructure. Only 4 studies primarily assessed pediatric cohorts yet all 47 studies were inclusive of children. Recognizing and removing barriers to treatment initiation for pediatric TB in sub-Saharan Africa are critical. Both patient- and system-level barriers must be better researched in order to improve patient outcomes.

To evaluate a tuberculosis control program in rural Haiti and to compare two strategies for treatment implemented in two areas that were not chosen at random: treatment delivered at the patients' homes observed by former tuberculosis patients (DOT), and non observed treatment (non-DOT). Retrospective analysis of the clinical records of adult patients diagnosed with tuberculosis at H pital Albert Schweitzer in Deschapelles, Haiti, during 1994-1995. There were 143 patients in the non-DOT group and 138 patients in the DOT group. The results of treatment were significantly different: in the non-DOT group 29% defaulted, 12% died and 58% had a successful outcome; in the DOT group 7% defaulted (P < 0.01), 4% died (P = 0.01) and 87% had a successful outcome (P < 0.01). These differences are also significant when considering only human immunodeficiency virus (HIV) infected patients (defaulted P < 0.01; died P = 0.09; successful outcome P < 0.01). Delivering treatment in patients' homes with direct observation by former tuberculosis patients can achieve good results, even in an area of extreme poverty and high rates of HIV infection. In this population the number of patients who are able to complete their treatment without observed administration is far from optimal.

    Many studies have suggested that sputum smear conversion after 2 months of antituberculosis treatment is an important determinant of treatment success and can be a predictor for relapse. The objective of this study is to determine the factors that influence sputum smear conversion after 2 months of treatment among pulmonary tuberculosis patients receiving treatment in the Institute of Respiratory Medicine in Kuala Lumpur, Malaysia. A total of 75 cases and 75 controls were interviewed, and their medical records were retrieved in order to extract the information needed. All analyses were conducted using SPSS version 17, and binary logistic regression analysis was used to determine the predictors of sputum smear nonconversion. Results showed that the following factors were associated with sputum smear positivity after 2 months of intensive treatment: diabetes mellitus (p=.013, odds ratio [OR]=2.59, 95% confidence interval [CI] 1.27-5.33), underweight body mass index (p=.025, OR=1.67, 95% CI 0.80-3.49), nonadherent to tuberculosis treatment (p=.024, OR=2.85, 95% CI 1.21-6.74), and previous history of tuberculosis (p=.043, OR=2.53, 95% CI 1.09-5.83). Multivariable analysis identified diabetes mellitus (p=.003, OR=4.01, 95% CI 1.61-9.96) as being independently associated with the risk of persistent sputum smear positivity after 2 months of intensive treatment. Based on the findings, identification of these factors is valuable in strengthening the management and treatment of tuberculosis in Malaysia in the future. This study emphasizes the importance of diabetes screening and integration of diabetic controls among tuberculosis patients in achieving better treatment outcome.

    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.

    Linezolid, an oxazolidinone, substantially improves treatment outcomes of multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis. We started a trial to test whether the use of linezolid instead of ethambutol could increase the rate of sputum culture conversion as of 8 weeks of treatment in patients with drug-susceptible tuberculosis. This is a phase II, multicenter, randomized study with three arms. We are enrolling patients with pulmonary tuberculosis without rifampicin resistance screened by the Xpert MTB/RIF® assay. The standard treatment arm uses isoniazid (6 months), rifampicin (6 months), pyrazinamide (2 months), and ethambutol (2 months). Experimental arm 1 uses linezolid (600 mg/day) for 4 weeks instead of ethambutol. Experimental arm 2 uses linezolid (600 mg/day) for 2 weeks instead of ethambutol. The primary outcome is the sputum culture conversion rate on liquid media after 2 months of treatment. Secondary outcomes include the sputum culture conversion rate on solid media after 2 months of treatment, time to sputum culture conversion on liquid and solid media, cure rate, and treatment success rate. The frequencies of total adverse events (AEs) and serious AEs will be described and documented. Based on an α = 0.05 level of significance, a power of 85%, a 15% difference in the culture conversion rate after 2 months between the control arm and experimental arm 1 (75% vs. 90%), a 10% default (loss to follow-up) rate, and a 10% culture failure, the required number per arm was calculated to be 143 (429 in total). This trial will reveal the effectiveness and safety of 2 or 4 weeks of use of linezolid instead of ethambutol for patients with drug-susceptible pulmonary tuberculosis. If a new regimen including linezolid shows a higher culture conversion rate by week 8, and is safe, it could be tested as a 4-month antituberculosis treatment regimen in the future.

    Full Text Available Background: Prospective observation analysis to evaluate the cure in tuberculous cervical lymphadenopathy with directly observed treatment short course category III (DOTS CAT III treatment as per revised national tuberculosis control program (RNTCP at a tertiary care hospital in AP, India, from October 2007 to September 2009. These cases were followed up for period of 22 months. Materials and Methods: Total 1521 tuberculous cases were screened in KIMS both pulmonary and extra pulmonary cases out of which 146 cases were tuberculous lymphadenitis. Fifty cases of tuberculous cervical lymphadenopathy were included after diagnostic and treatment algorithm and fine needle biopsy or excision biopsy. Patients below 5 yrs, immunocompromised, having diabetes mellitus, pulmonary tuberculosis and with other co-morbid conditions were excluded from the study. All patients were put on DOTS CAT III as per RNTCP guidelines. Follow-up was done every 2 months till 6 months for 1 Constitution symptoms 2 Weight gain or loss 3 Appetite gain or loss 4 Regression of lymph nodes or increase 5 Compliance 6 Side effects 7 Failures by demonstration of organism by direct smear, culture or histopathological examination. Results: In this study, lymph node regression was found in 78% at the end of 2 months, 94% at the end of 4 months and 96% at the end of 6 months, 9 patients had regression in size though the nodes were palpable, 2 had no regression but fresh lymph nodes appeared on the same side and sinus discharge was present, culture was negative in these cases. Two cases had immune reconstitution syndrome, constitutional symptoms disappeared and showed clinical improvement. Four cases were subjected for surgical intervention. Conclusion: DOTS CAT III is effective in the treatment of tuberculous cervical lymphadenopathy. Compliance was good with minimal, minor side effects, only two had immune reconstitution syndrome and two had sinus formation; they were referred for

    Greater Mymensingh District, a rural area of Bangladesh, at the start of the National Tuberculosis Programme (NTP). To determine the prevalence of initial and acquired drug resistance of Mycobacterium tuberculosis, and to assess the appropriateness of the NTP's standard regimens. Sampling of pre-treatment sputum from all newly registered smear-positive cases in five centres covering the area. Culture and susceptibility testing in a supra-national reference laboratory. Initial resistance to isoniazid (H) was 5.4%, and to rifampicin (R) 0.5%. Acquired H and R resistance were 25.9% and 7.4%, respectively. Multidrug resistance (MDR) was observed in one new case only and in 5.6% of previously treated patients. Changing the present NTP indication for retreatment regimen to one month of previous H intake would increase coverage of H-resistant cases from 52% to 89%, adding 6% to drug costs. The prevalence of drug resistance is surprisingly low in Bangladesh, but could rise with improving economic conditions. The NTP regimens for smear-positive cases are appropriate, all the more so since the human immunodeficiency virus is virtually absent. Indications for the retreatment regimen should be extended to include all patients treated for at least one month with any drug. The NTP regimen for smear-negative cases runs the risk of leading to MDR under present field conditions.

    2012-01-01

    Towards the end of the 19th century, Europe turned particular attention to the problem of tuberculosis, at that time the most serious social disease. In the majority of cases, pulmonary tuberculosis had a fatal outcome owing to the lack of effective drugs and methods of treatment. Due to poor sanitary conditions, particularly as regards dwellings, pulmonary tuberculosis was able to spread rapidly. Hospital departments were reluctant to admit patients suffering from tuberculosis. It was only after the discoveries of Robert Koch (bacillus tubercle in 1882) that the cause of the disease became understood and methods of treatment began to be developed. A modern sanatorium and hospital with 270 beds was erected in Hohenkrug (today Szczecin-Zdunowo) between 1915 and 1930. Patients could now be treated with modern methods, surgically in most cases. After the Second World War, pulmonary tuberculosis was still an enormous epidemiologic problem. In 1949, the Polish authorities opened a 400-bed sanatoriumin Zdunowo. The methods of treatment were not much different from pre-war practice and it was only the routine introduction of antituberculotic drugs during the fifties of the past century that brought about a radical change in the fight against tuberculosis. The growing numbers of patients with tuberculosis of the genitourinary system led to the opening in 1958 of a 40-bed specialist ward at the Tuberculosis Sanatorium in Zdunowo. It should be emphasized that the Department of Genitourinary Tuberculosis in Szczecin-Zdunowo was a historical necessity and a salvation for thousands of patients from Northern Poland. The Department totally fulfilled its social duties thanks to the commitment of many outstanding persons dedicated to helping the patients. This unit was finally closed in 1987 because the demand for surgical treatment of tuberculosis was declining concurrently with the advent of new and potent antituberculotics and falling number of new cases of genitourinary

    Cambodia is one of the 22 countries with a high burden of tuberculosis (TB). People often first seek treatment for cough and other TB symptoms through private pharmacies. The National Tuberculosis Programme trained willing private sector pharmacies to refer TB symptomatic clients to their closest public sector clinic for diagnosis and treatment. The study objective was to investigate factors associated with referral of TB symptomatic clients from pharmacies to public sector clinics in Phnom Penh, Cambodia. Face-to-face structured interviews were conducted with staff from a stratified random sample of 180 private pharmacies in Phnom Penh in 2012. Trained interviewers were Khmer speakers. Logistic regression was used to compute odds ratios (ORs) and 95% confidence intervals (CIs) for factors associated with self-reported referral during the previous 3 months. Fifty (29.6%) pharmacies reported that they had referred 125 clients (range 1-10) to public sector clinics during the previous 3 months. In total, 164 (96.5%) pharmacies reported that they always referred all TB symptomatic clients to DOTS (directly observed treatment, short course) clinics. More than 6-year participation in the programme (OR 5.23, 95% CI 1.93-14.18) and willingness to always continue referring (OR 12.24, 95% CI 11.61-93.10) were associated with referral of one or more clients in the previous 3 months. Referral to the client's closest clinic was negatively associated with referral (OR 0.45, 95% CI 0.23-0.99). Pharmacies' ongoing commitment to the Referral Programme was strongly associated with referral. Increased advocacy among the high number of non-referring pharmacies may improve programme performance. Factors negatively associated with referral may need investigation. © 2015 The Authors. Journal of Evaluation in Clinical Practice published by John Wiley & Sons, Ltd.

    In pregnant women who have been exposed to tuberculosis (TB), primary isoniazid prophylaxis is only recommended in cases of immunosuppression, chronic medical conditions or obstetric risk factors, and close and sustained contact with a patient with infectious TB. Isoniazid prophylaxis for latent tuberculosis infection (LTBI) is recommended in women who have close contact with an infectious TB patient or have risk factors for progression to active disease. Otherwise, it should be delayed until at least three weeks after delivery. Treatment of TB disease during pregnancy is the same as for the general adult population. Infants born to mothers with disseminated or extrapulmonary TB in pregnancy, with active TB at delivery, or with postnatal exposure to TB, should undergo a complete diagnostic evaluation. Primary isoniazid prophylaxis for at least 12 weeks is recommended for those with negative diagnostic tests and no evidence of disease. Repeated negative diagnostic tests are mandatory before interrupting prophylaxis. Isoniazid for 9 months is recommended in LTBI. Treatment of neonatal TB disease is similar to that of older children, but should be maintained for at least 9 months. Respiratory isolation is recommended in congenital TB, and in postnatal TB with positive gastric or bronchial aspirate acid-fast smears. Separation of mother and infant is only necessary when the mother has received treatment for less than 2 weeks, is sputum smear-positive, or has drug-resistant TB. Breastfeeding is not contraindicated, and in case of mother-infant separation expressed breast milk feeding is recommended. Copyright © 2014 Asociación Española de Pediatría.

    Full Text Available The antioxidant enzyme heme oxygenase-1 (HO-1 is implicated in the pathogenesis of tuberculosis (TB and has been proposed as a biomarker of active disease. Nevertheless, the mechanisms by which Mycobacterium tuberculosis (Mtb induces HO-1 as well as how its expression is affected by HIV-1 coinfection and successful antitubercular therapy (ATT are poorly understood. We found that HO-1 expression is markedly increased in rabbits, mice, and non-human primates during experimental Mtb infection and gradually decreased during ATT. In addition, we examined circulating concentrations of HO-1 in a cohort of 130 HIV-1 coinfected and uninfected pulmonary TB patients undergoing ATT to investigate changes in expression of this biomarker in relation to HIV-1 status, radiological disease severity, and treatment outcome. We found that plasma levels of HO-1 were elevated in untreated HIV-1 coinfected TB patients and correlated positively with HIV-1 viral load and negatively with CD4+ T cell count. In both HIV-1 coinfected and Mtb monoinfected patients, HO-1 levels were substantially reduced during successful TB treatment but not in those who experienced treatment failure or subsequently relapsed. To further delineate the molecular mechanisms involved in induction of HO-1 by Mtb, we performed a series of in vitro experiments using mouse and human macrophages. We found that Mtb-induced HO-1 expression requires NADPH oxidase-dependent reactive oxygen species production induced by the early-secreted antigen ESAT-6, which in turn triggers nuclear translocation of the transcription factor NRF-2. These observations provide further insight into the utility of HO-1 as a biomarker of both disease and successful therapy in TB monoinfected and HIV-TB coinfected patients and reveal a previously undocumented pathway linking expression of the enzyme with oxidative stress.

    Full Text Available Nowadays, the greatest concern of tuberculosis control programmes is the appearance of multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis. Rapid determination of drug resistance in clinical samples, with Mycobacterium tuberculosis complex (MTC, is the prerequisite for initiating effective chemotherapy, ensuring successful treatment of the patient and preventing further spread of drugresistant isolates.The aim of our study was to determine the sensitivity of the new MTBDRplus® assay in comparison to culture, identification and classic DST, directly from smear-positive clinical specimens.A total of 68 smear-positive sputum specimens were processed by both the classical mycobacteriological methods and the molecular assay, MTBDRplus®.MTBDRplus® assay allowed an accurate identification of MTC species by detection of the specific band in all samples, from which we also isolated and identified MTC strains by culture methods. In the samples from which we isolated susceptible strains (63.2%, wild type patterns were found using MTBDRplus® assay. The samples from which we isolated resistant strains (36.8% showed specific mutations associated with the correspondent resistant phenotype.Our study indicated that this assay allows rapid detection of resistance, always in agreement with classic methods.

    Full Text Available Abstract Background Few data are available on prescriber adherence to tuberculosis (TB treatment guidelines. In particular, excessively long treatment carries a risk of avoidable adverse effects and represents a waste of healthcare resources. We examined factors potentially associated with excessively long treatment. Methods We reviewed the medical records of patients diagnosed with TB in 2004 in the eastern Paris region. Sociodemographic and clinical factors associated with excessively long treatment were identified by logistic regression analyses. Based on contemporary guidelines, excessively long treatment was defined as more than 6 months of a four-drug regimen for thoracic TB with full sensitive strains, and more than 12 months for patients with extrathoracic TB. Results Analyses concerned 478 patients with a median age of 36.0 ± 13.5 years, of whom 48% were living in precarious conditions (i.e. poor living conditions and/or no health insurance, 80% were born abroad, and 17% were HIV-seropositive. TB was restricted to the chest in 279 patients (isolated pulmonary, pleuropulmonary, and isolated pleural TB in 245, 13, and 21 patients, respectively, exclusively extrathoracic in 115 patients, and mixed in the remaining 84 patients. Treatment was prescribed by a chest specialist in 211 cases (44.1% and 295 patients (61.7% were managed in a single institution. The treatment duration complied with contemporary guidelines in 316 cases (66.1% and was excessively long in 162 cases (33.9%. The median duration of excessively long treatment was 313 days (IQR: 272-412. In multivariate analysis, isolated thoracic TB, previous TB, HIV infection, a prescriber other than a chest specialist, and management in more than one healthcare center during treatment were independently associated with excessively lengthy treatment. Conclusion One-third of TB patients received excessively long treatment, reflecting inadequate awareness of management guidelines or

    The present work is a review of the remedies in use in Ferrara against tuberculosis in the 1800s. The work started from the discovery of accounts describing methods and remedies. These remedies were also in use world wide. Of particular interest is the work by Antonio Campana, a famous professor of Pharmaceutical Chemistry and Botany in Ferrara, who wrote a pharmacopoeia which had several editions between 1797 and 1841. The Farmacopea Ferrarese was addressed to the apothecaries of Ferrara. Nevertheless, due to its great reputation it had an international distribution. It provided us with an exhaustive view about the medical field in Ferrara in the early 1800s. The remedies adopted in the city in the second half of the century were in line with those present abroad. The work was also supported by the discovery of statistical accounts of the Sant'Anna hospital from 1871. The manuscript written by Alessandro Bennati enabled elucidation of the methods used to treat tuberculosis in the second half of the century. Bennati's work is an historical document completed by the work of the physician Cesare Minerbi.

    The appearance of smear-positivity but culture-negativity (SPCN) for acid-fast bacilli among sputum specimen is frequently found in pulmonary tuberculosis (TB) patients during treatment. This study aimed to investigate clinical risk factors, impacts on treatment course, and relapse pattern associated with sputum SPCN. We retrospectively enrolled 800 patients with culture-proven pulmonary TB who were receiving standard treatment and follow-up at six TB-referral hospitals in Taiwan between January 2006 and December 2007. Relevant patient characteristics and chemotherapy data were analyzed for associations with incidence of SPCN. Data from patients who relapsed within 3 years after completing treatment were analyzed for associations with SPCN during treatment. Of the 800 subjects, 111 (13.8%) had sputum SPCN during treatment. Three factors were found to predict the development of SPCN; namely, high initial acid-fast staining grading (OR, 3.407; 95% CI, 2.090-5.553), cavitation on chest-X ray films (OR, 2.217; 95% CI, 1.359-3.615), and smoking (OR, 1.609; 95% CI, 1.006-2.841). Patients with SPCN had longer treatment duration (rifampicin: 284 ± 91 vs. 235 ± 69 days, P <0.001; isoniazid: 289 ± 90 vs. 234 ± 69 days, P < 0.001) than those without SPCN. Finally, the rate of relapse within 3 years of completing treatment was similar for groups with/without SPCN (2.7%, 3/111 vs. 1.0%, 7/689, respectively; P = 0.15). In conclusion, severity of infection was a major risk factor for SPCN during treatment; however, the relapse rate within 3 years of completing treatment was not affected by the appearance of SPCN.

    Full Text Available Background: The tuberculosis (TB literature is written almost entirely from a biomedical perspective, while recent studies show that it is imperative to understand lay perception to determine why people seek treatment and may stop taking treatment. Aims: To investigate knowledge about TB, perceptions of (access to TB treatment, and adherence to treatment among a Pakistani population. Setting and Design: Descriptive cross-sectional study. Materials and Methods: A total of 175 participants were selected nonrandomly, 100 were TB patient and 75 were non-TB patient in proportion to the total number of participants in each ward of hospital. Statistical Analysis: Analysis of attitudes and perceptions toward TB, adherence to TB treatment, health seeking behavior, and TB treatment types done by frequency counts and percentages. Regression analysis and logistic regression analysis were performed to test whether differences in age, gender, and education level led to different knowledge scores and different attitudes and preferences toward TB, adherence to TB treatment, health seeking behavior, and TB treatment types. All statistical analyses were performed using Statistical Package for Social Sciences (SPSS 16.0. Result: TB knowledge can be considered fairly well among this community. Respondents′ perceptions suggest that stigma may influence TB patients′ decision in health seeking behavior and adherence to TB treatment. A full 95% of those interviewed believe people with TB tend to hide their TB status out of fear of what others may say. Conclusion: Most of the subjects were unaware of TB that seems to be due to their illiteracy and those who knew had got the knowledge from media, but the majority of the patients who were on directly observed treatment, short-course (DOTS were found to be satisfied.

    A major problem resulting from interrupted tuberculosis (TB) treatment is the development of drug-resistant TB, including multidrug-resistant TB (MDR TB), a more deadly and costly-to-treat form of the disease. Global health systems are not equipped to diagnose and treat the current burden of MDR TB. TB-infected foreign visitors and temporary US residents who leave the country during treatment can experience treatment interruption and, thus, are at greater risk for drug-resistant TB. Using epidemiologic and demographic data, we estimated TB incidence among this group, as well as the proportion of patients referred to transnational care-continuity and management services during relocation; each year, ≈2,827 visitors and temporary residents are at risk for TB treatment interruption, 222 (8%) of whom are referred for transnational services. Scale up of transnational services for persons at high risk for treatment interruption is possible and encouraged because of potential health gains and reductions in healthcare costs for the United States and receiving countries.

    Background Although tuberculosis (TB) care is provided free of charge in Morocco, a high number of patients voluntarily interrupt their treatment before the end. Treatment Default is a major obstacle in the fight against the disease. The purpose of this study was to describe the impact of knowledge and attitudes toward TB on treatment adherence. Methods Case-control study of 290 TB patients (85 defaulters and 205 controls). A defaulter was defined as a TB patient who interrupted treatment for two months or longer. Socio-demographic measurements, knowledge and attitude were collected by face to face anonymous questionnaire. Khi-square test was conducted to examine differences in TB attitudes and knowledge according to treatment adherence. Results The mean age of participants was 31.7 ± 12.0 years. Monthly income was under 2000 MAD (180 €) for 82% of them. Over sixty four percent were illiterate or had a basic educational level. Microbial cause was known by 17.2% respondents; 20.5% among adherent patients versus 9.4% (p=0.02). The fact that the disease is curable was more known by adherent patients: 99.0% versus 88.2% (p education into current TB case management. PMID:22937192

    Acquired resistance to antituberculosis drugs decreases effective treatment options and the likelihood of treatment success. We identified risk factors for acquisition of drug resistance during treatment for multidrug-resistant tuberculosis (MDR TB) and evaluated the effect on treatment outcomes. Data were collected prospectively from adults from Arkhangelsk Oblast, Russia, who had pulmonary MDR TB during 2005–2008. Acquisition of resistance to capreomycin and of extensively drug-resistant TB were more likely among patients who received 3 effective drugs (9.4% vs. 0% and 8.6% vs. 0.8%, respectively). Poor outcomes were more likely among patients with acquired capreomycin resistance (100% vs. 25.9%), acquired ofloxacin resistance (83.6% vs. 22.7%), or acquired extensive drug resistance (100% vs. 24.4%). To prevent acquired drug resistance and poor outcomes, baseline susceptibility to first- and second-line drugs should be determined quickly, and treatment should be adjusted to contain >3 effective drugs.

    Tuberculosis (TB) among healthcare workers (HCWs) highly affects morbidity and TB transmission in hospitals. A retrospective cohort study of TB among HCWs (HCW-TB) was conducted using a registered database from 2003 to 2016 at Chiang Mai University Hospital to determine clinical and microbiological characteristics and treatment outcomes of HCW-TB. A total of 76 patients comprising 54 nurses (71.1%), 12 physicians (15.8%), and 10 paramedics (13.2%) were diagnosed with TB disease. The men to women ratio was 25:51, with a mean age of 37.0±11.6 years, a median work duration of 12.0 years (5-20) and a body mass index of 19.4±2.5 kg/m 2 . Within the HCW-TB group, 28 (36.8%) worked in the Medical Department, 12 (15.8%) worked in the Outpatient Department/Emergency Room, and 9 (11.8%) worked in the Surgical Department. Pulmonary TB (PTB) was the most common manifestation of HCW-TB (92.1%). Sputum acid-fast stains were positive among 28 (40.0%) HCWs with PTB. Mycobacterium tuberculosis cultures were positive in 26 (34.2%) patients. Drug susceptibility testing showed sensitivity to all first-line drugs (75.0%), resistance to any one first-line drug (20.8%), and multidrug-resistant TB comprised 4.2%. The end-of-treatment success rate was 100%. Therefore, TB control guidelines should be strictly implemented to prevent TB transmission in healthcare settings.

    Bacterial dormancy is a major impediment to the eradication of tuberculosis (TB), because currently used drugs primarily target actively replicating bacteria. Therefore, decoding of the critical survival pathways in dormant tubercle bacilli is a research priority to formulate new approaches for killing these bacteria. Employing a network-based gene expression analysis approach, we demonstrate that redox active vitamin C (vit C) triggers a multifaceted and robust adaptation response in Mycobacterium tuberculosis (Mtb) involving ~ 67% of the genome. Vit C-adapted bacteria display well-described features of dormancy, including growth stasis and progression to a viable but non-culturable (VBNC) state, loss of acid-fastness and reduction in length, dissipation of reductive stress through triglyceride (TAG) accumulation, protective response to oxidative stress, and tolerance to first line TB drugs. VBNC bacteria are reactivatable upon removal of vit C and they recover drug susceptibility properties. Vit C synergizes with pyrazinamide, a unique TB drug with sterilizing activity, to kill dormant and replicating bacteria, negating any tolerance to rifampicin and isoniazid in combination treatment in both in-vitro and intracellular infection models. Finally, the vit C multi-stress redox models described here also offer a unique opportunity for concurrent screening of compounds/combinations active against heterogeneous subpopulations of Mtb. These findings suggest a novel strategy of vit C adjunctive therapy by modulating bacterial physiology for enhanced efficacy of combination chemotherapy with existing drugs, and also possible synergies to guide new therapeutic combinations towards accelerating TB treatment.

    Our objective was to evaluate the incidence of colorectal tuberculosis in our series and to study its radiological spectrum. A total of 684 cases of proven gastrointestinal tuberculosis with positive barium contrast findings seen over a period of more than one decade were evaluated. The study did not include cases where colon was involved in direct contiguity with ileo-caecal tuberculosis. Seventy-four patients (10.8%) had colorectal tuberculosis. Commonest site involved was transverse colon, closely followed by rectum and ascending colon. Radiological findings observed were in the form of strictures (54%), colitis (39%) and polypoid lesions (7%). Complications noted were in the form of perforations and fistulae in 18.9% of cases. Colorectal tuberculosis is a very common site for gastrointestinal tuberculosis. Typical findings of colorectal tuberculosis are strictures, signs of colitis and polypoid lesions. Common complications are perforation and fistulae. (orig.)

    Although the discovery of effective anti-tuberculosis drugs has made uncomplicated spinal tuberculosis a medical disease, the advent of multi-drug-resistant Mycobacterium tuberculosis and the co-infection of HIV with tuberculosis have led to a resurgence of the disease recently. The principles of drug treatment of spinal tuberculosis are derived from our experience in treating pulmonary tuberculosis. Spinal tuberculosis is classified to be a severe form of extrapulmonary tuberculosis and hence is included in Category I of the WHO classification. The tuberculosis bacilli isolated from patients are of four different types with different growth kinetics and metabolic characteristics. Hence multiple drugs, which act on the different groups of the mycobacteria, are included in each anti-tuberculosis drug regimen. Prolonged and uninterrupted chemotherapy (which may be 'short course' and 'intermittent' but preferably 'directly observed') is effective in controlling the infection. Spinal Multi-drug-resistant TB and spinal TB in HIV-positive patients present unique problems in management and have much poorer prognosis. Failure of chemotherapy and emergence of drug resistance are frequent due to the failure of compliance hence all efforts must be made to improve patient compliance to the prescribed drug regimen.

    Full Text Available Tuberculosis (TB is one of the major public health and socio-economic issues in the 21st century globally. Assessment of TB treatment outcomes, and monitoring and evaluation of its risk factors in Directly Observed Treatment Short Course (DOTS are among the major indicators of the performance of a national TB control program. Hence, this institution-based retrospective study was conducted to determine the treatment outcome of TB patients and investigate factors associated with unsuccessful outcome at Dilla University Referral Hospital, southern Ethiopia. Five years (2008 to 2013 TB record of TB clinic of the hospital was reviewed. A total 1537 registered TB patients with complete information were included. Of these, 942 (61.3% were male, 1015 (66% were from rural areas, 544 (35.4% were smear positive pulmonary TB (PTB+, 816 (53.1% were smear negative pulmonary TB (PTB- and 177(11.5% were extra pulmonary TB (EPTB patients. Records of the 1537 TB patients showed that 181 (11.8% were cured, 1129(73.5% completed treatment, 171 (11.1% defaulted, 52 (3.4% died and 4 (0.3% had treatment failure. The overall mean treatment success rate of the TB patients was 85.2%. The treatment success rate of the TB patients increased from 80.5% in September 2008-August 2009 to 84.8% in September 2012-May 2013. Tuberculosis type, age, residence and year of treatment were significantly associated with unsuccessful treatment outcome. The risk of unsuccessful outcome was significantly higher among TB patients from rural areas (AOR = 1.63, 95% CI: 1.21-2.20 compared to their urban counterparts. Unsuccessful treatment outcome was also observed in PTB- patients (AOR = 1.77, 95% CI: 1.26-2.50 and EPTB (AOR = 2.07, 95% CI: 1.28-3.37 compared to the PTB+ patients. In conclusion, it appears that DOTS have improved treatment success in the hospital during five years.

    Full Text Available This study analyzed the limitations and strengths of the Directly Observed Treatment Short-Course (DOTS for tuberculosis from the perspective of patients and healthcare providers in a Technical Health Supervision unit in the city of São Paulo, SP, Brazil. Four patients and 17 healthcare providers from nine Primary Care Units were interviewed from April to June 2006, after signing free and informed consent forms. The reports were decoded according to the speech analysis technique. The Theory of the Social Determination of the Health-Disease Process was adopted as the theoretical framework. The strengths were: establishment of bonds between healthcare providers and patients and the introduction of incentives, which promotes treatment adherence. Limitations included: restricted involvement of DOTS' healthcare providers and reconciling patients' working hours with supervision. Treatment adherence goes beyond the biological sphere and healthcare providers should acknowledge patients' needs that go beyond the supervision of medication taken.Se objetivó analizar potencialidades y límites de la estrategia del Tratamiento Supervisado (DOTS para la tuberculosis bajo la percepción de los usuarios en tratamiento y de los trabajadores de la salud de una Supervisión Técnica de Salud del Municipio de Sao Paulo.

    To assess the approach of specialists to ocular tuberculosis (TB). The American Uveitis Society (AUS) Listserv was surveyed using two clinical cases and general questions. Of 196 members, 87 responded (44.4%), of whom 64 were affiliated with practices in North America, while 23 were outside of North America. The survey provided normative data on how physicians evaluate patients with uveitis as well as opinions about ocular TB. Responses varied widely on such issues as (1) the pretest probability that a patient with granulomatous panuveitis had TB uveitis (range 1-75%) or that a patient with a risk factor for TB had ocular TB (range 0-90%); (2) the optimal duration of anti-TB therapy; and (3) whether therapy should be discontinued after 2 months in nonresponders. Consensus is lacking among uveitis specialists for the diagnosis or management of ocular TB.

  7. Analysis of combination drug therapy to develop regimens with shortened duration of treatment for tuberculosis.

    Full Text Available Tuberculosis remains a worldwide problem, particularly with the advent of multi-drug resistance. Shortening therapy duration for Mycobacterium tuberculosis is a major goal, requiring generation of optimal kill rate and resistance-suppression. Combination therapy is required to attain the goal of shorter therapy.Our objective was to identify a method for identifying optimal combination chemotherapy. We developed a mathematical model for attaining this end. This is accomplished by identifying drug effect interaction (synergy, additivity, antagonism for susceptible organisms and subpopulations resistant to each drug in the combination.We studied the combination of linezolid plus rifampin in our hollow fiber infection model. We generated a fully parametric drug effect interaction mathematical model. The results were subjected to Monte Carlo simulation to extend the findings to a population of patients by accounting for between-patient variability in drug pharmacokinetics.All monotherapy allowed emergence of resistance over the first two weeks of the experiment. In combination, the interaction was additive for each population (susceptible and resistant. For a 600 mg/600 mg daily regimen of linezolid plus rifampin, we demonstrated that >50% of simulated subjects had eradicated the susceptible population by day 27 with the remaining organisms resistant to one or the other drug. Only 4% of patients had complete organism eradication by experiment end.These data strongly suggest that in order to achieve the goal of shortening therapy, the original regimen may need to be changed at one month to a regimen of two completely new agents with resistance mechanisms independent of the initial regimen. This hypothesis which arose from the analysis is immediately testable in a clinical trial.

Lipid nanoparticles, specifically nanostructured lipid carriers (NLC, were synthetized by the high-shear homogenization and ultrasonication techniques. These nanoparticles were designed to exhibit both passive and active targeting strategies to be efficiently internalized by the alveolar macrophages, traffic to the acidified phagosomes and phagolysosomes, and release bactericidal concentrations of the antituberculosis drug intracellularly. NLC that could entrap RFB were prepared, characterized, and further functionalized with mannose. Particles’ diameter, zeta potential, morphology, drug% entrapping efficiency, and drug release kinetics were evaluated. The mannose coating process was confirmed by Fourier transform infrared. Further, the cytotoxicity of the formulations was evaluated by 3-(4,5-dimethylthiazol-2-yl-2,5 diphenyltetrazolium bromide (MTT assay in A549, Calu-3, and Raw 264.7 cells. The diameter of NLC formulations was found to be in the range of 175–213 nm, and drug entrapping efficiency was found to be above 80%. In addition, high storage stability for the formulations was expected since they maintained the initial characteristics for 6 months. Moreover, the drug release was pH-sensitive, with a faster drug release at acidic pH than at neutral pH. These results pose a strong argument that the developed nanocarrier can be explored as a promising carrier for safer and more efficient management of tuberculosis by exploiting the pulmonary route of

    Polymorphisms in SLC11A1/NRAMP1 have shown an important association with susceptibility to tuberculosis and progression to active disease. However, whether there is an association of these polymorphisms with treatment failure is unknown. The aim of this study was to determine the association of SLC11A1 polymorphisms with treatment failure in Mexican subjects with pulmonary tuberculosis. Thirty-three subjects with treatment failure were paired by age and body mass index with 33 patients who successfully completed treatment and were considered cured. We assessed the polymorphisms of SLC11A1 in the regions of D543N and INT4 via polymerase chain reaction real-time TaqMan® single nucleotide polymorphism (SNP) genotyping. We found that D543N (G/A genotype) was associated with treatment failure in patients with pulmonary tuberculosis [odds ratio (OR) 11.61, 95% confidence interval (CI) 3.66-36.78]. When adjusted by gender, this association remained significant in males (OR 11.09, 95% CI 3.46-35.51). In our male population, the presence of the D543N polymorphism of SLC11A1 is a risk factor for treatment failure. This finding should be confirmed in other populations.

    Full Text Available Isoniazid and rifampicin are the two most efficacious first-line agents for tuberculosis (TB treatment. We assessed the prevalence of isoniazid and rifampicin mono-resistance, associated risk factors, and the association of mono-resistance on treatment outcomes.A prospective, observational cohort study enrolled adults with a first episode of smear-positive pulmonary TB from 34 health facilities in a northern district of Lima, Peru, from March 2010 through December 2011. Participants were interviewed and a sputum sample was cultured on Löwenstein-Jensen (LJ media. Drug susceptibility testing was performed using the proportion method. Medication regimens were documented for each patient. Our primary outcomes were treatment outcome at the end of treatment. The secondary outcome included recurrent episodes among cured patients within two years after completion of the treatment.Of 1292 patients enrolled, 1039 (80% were culture-positive. From this subpopulation, isoniazid mono-resistance was present in 85 (8% patients and rifampicin mono-resistance was present in 24 (2% patients. In the multivariate logistic regression model, isoniazid mono-resistance was associated with illicit drug use (adjusted odds ratio (aOR = 2.10; 95% confidence interval (CI: 1.1-4.1, and rifampicin mono-resistance was associated with HIV infection (aOR = 9.43; 95%CI: 1.9-47.8. Isoniazid mono-resistant patients had a higher risk of poor treatment outcomes including treatment failure (2/85, 2%, p-value<0.01 and death (4/85, 5%, p<0.02. Rifampicin mono-resistant patients had a higher risk of death (2/24, 8%, p<0.01.A high prevalence of isoniazid and rifampicin mono-resistance was found among TB patients in our low HIV burden setting which were similar to regions with high HIV burden. Patients with isoniazid and rifampicin mono-resistance had an increased risk of poor treatment outcomes.

  12. Differences in reactivation of tuberculosis induced from anti-TNF treatments are based on bioavailability in granulomatous tissue.

    2007-10-01

    Full Text Available The immune response to Mycobacterium tuberculosis (Mtb infection is complex. Experimental evidence has revealed that tumor necrosis factor (TNF plays a major role in host defense against Mtb in both active and latent phases of infection. TNF-neutralizing drugs used to treat inflammatory disorders have been reported to increase the risk of tuberculosis (TB, in accordance with animal studies. The present study takes a computational approach toward characterizing the role of TNF in protection against the tubercle bacillus in both active and latent infection. We extend our previous mathematical models to investigate the roles and production of soluble (sTNF and transmembrane TNF (tmTNF. We analyze effects of anti-TNF therapy in virtual clinical trials (VCTs by simulating two of the most commonly used therapies, anti-TNF antibody and TNF receptor fusion, predicting mechanisms that explain observed differences in TB reactivation rates. The major findings from this study are that bioavailability of TNF following anti-TNF therapy is the primary factor for causing reactivation of latent infection and that sTNF--even at very low levels--is essential for control of infection. Using a mathematical model, it is possible to distinguish mechanisms of action of the anti-TNF treatments and gain insights into the role of TNF in TB control and pathology. Our study suggests that a TNF-modulating agent could be developed that could balance the requirement for reduction of inflammation with the necessity to maintain resistance to infection and microbial diseases. Alternatively, the dose and timing of anti-TNF therapy could be modified. Anti-TNF therapy will likely lead to numerous incidents of primary TB if used in areas where exposure is likely.

    Full Text Available Despite successful implementation of directly observed treatment, short course (DOTS in India, the growing number of diabetes mellitus (DM patients appears to be a cause in the increasing tuberculosis (TB incidence, affecting their management. In this regard, a prospective study was conducted on DOTS patients in three primary health care centers in urban slum region of South Delhi, India, to evaluate the effect of DM on sputum conversion, treatment outcome, and adverse drug reactions (ADR due to anti-TB treatment. Eligible TB patients underwent blood glucose screening at treatment initiation. Disease presentation, clinical outcome, and ADRs were compared between patients of TB with and without DM. Out of 316 patients, the prevalence of DM was found to be 15.8%, in which 19.4% and 9.6% were PTB and EPTB patients, respectively.

    Tuberculosis (TB) remains one of the deadliest infectious diseases worldwide, with a disproportionate number of those affected living in slum areas. We assessed the magnitude of pulmonary cases among tuberculosis patients in an urban slum in southeast Nigeria, their demographic and clinical characteristics and any associations with treatment outcomes. A retrospective cohort study of patients registered under the National TB Programme (NTP) from 1 January to 31 December 2012 was carried out. Data were extracted from TB treatment cards and registers. Of 647 new TB patients registered, 555 (85.8%) were pulmonary TB (PTB) with a mean age of 34.5years, and a male/female ratio of 1.3. Among these, 468 (84.3%) were smear-positive, while 87 (15.7%) were smear-negative cases. Twenty-one (3.8%) were children younger than 15years old. TB/HIV co-infection rate was 16.9%; 57.4% received antiretroviral therapy (ART) and 88.3% received cotrimoxazole preventive therapy (CPT). Female patients were significantly younger compared to male patients (p=0.003), had higher proportions of smear-negative TB (p=0.001) and HIV-positive status (p⩽0.001). Treatment success rate was 88.5% among smear-positive patients and 79.3% among smear-negative patients. More patients with smear-negative TB were lost to follow up compared with smear-positive TB patients (p<0.02). HIV co-infection was associated with unfavourable treatment outcomes (OR 0.2, CI 0.1-0.4, p⩽0.001). Among them, those who received ART had better outcomes. The study revealed high proportion of PTB, mostly smear-positive TB with HIV-associated outcomes and underlines the need to ensure early TB diagnosis and improved access to HIV care for HIV co-infected patients in this setting.

    To investigate early detection of amikacin-induced ototoxicity in a population treated for multidrug-resistant tuberculosis (MDR-TB), by means of three different tests: pure-tone audiometry (PTA); high-frequency audiometry (HFA); and distortion-product otoacoustic emission (DPOAE) testing. This was a longitudinal prospective cohort study involving patients aged 18-69 years with a diagnosis of MDR-TB who had to receive amikacin for six months as part of their antituberculosis drug regimen for the first time. Hearing was assessed before treatment initiation and at two and six months after treatment initiation. Sequential statistics were used to analyze the results. We included 61 patients, but the final population consisted of 10 patients (7 men and 3 women) because of sequential analysis. Comparison of the test results obtained at two and six months after treatment initiation with those obtained at baseline revealed that HFA at two months and PTA at six months detected hearing threshold shifts consistent with ototoxicity. However, DPOAE testing did not detect such shifts. The statistical method used in this study makes it possible to conclude that, over the six-month period, amikacin-associated hearing threshold shifts were detected by HFA and PTA, and that DPOAE testing was not efficient in detecting such shifts.

    Full Text Available Background: In the treatment of active tuberculosis, therapeutic drug monitoring (TDM is used to optimize dosing that maximizes therapeutic benefit while minimizing toxicity. In Morocco, TDM is not routinely used, yet low levels of anti-TB drugs can be associated with poorer treatment outcomes.Methods: We retrospectively checked our archives for patients with active TB for whom TDM was performed during 2014. Medical records were reviewed to abstract demographic, clinical, radiographic and microbiological data including time until smear and culture conversion. Then, we looked for cases with delay of TB conversion.Results: In total, 24 patients were identified, for whom TDM was performed, they all had low serum drug levels. Among them, 4 patients showed delayed bacteriological conversion.Conclusions: Our study cases are showing the benefit of serum dosage in the follow-up of the patients showing a delay of sputum examination conversion, both direct and culture, during their evolutions. TDM is potentially useful for the treatment of active TB, but is currently underused in Morocco.

    Multidrug drug resistant Tuberculosis (MDR-TB) and extensively drug resistant Tuberculosis (XDR-TB) have emerged as significant public health threats worldwide. This systematic review and meta-analysis aimed to investigate the effects of community-based treatment to traditional hospitalization in improving treatment success rates among MDR-TB and XDR-TB patients in the 27 MDR-TB High burden countries (HBC). We searched PubMed, Cochrane, Lancet, Web of Science, International Journal of Tuberculosis and Lung Disease, and Centre for Reviews and Dissemination (CRD) for studies on community-based treatment and traditional hospitalization and MDR-TB and XDR-TB from the 27 MDR-TB HBC. Data on treatment success and failure rates were extracted from retrospective and prospective cohort studies, and a case control study. Sensitivity analysis, subgroup analyses, and meta-regression analysis were used to explore bias and potential sources of heterogeneity. The final sample included 16 studies involving 3344 patients from nine countries; Bangladesh, China, Ethiopia, Kenya, India, South Africa, Philippines, Russia, and Uzbekistan. Based on a random-effects model, we observed a higher treatment success rate in community-based treatment (Point estimate = 0.68, 95 % CI: 0.59 to 0.76, p   18 months, and regimen with drugs >5 reported higher treatment success rate. In the meta-regression model, age of patients, adverse events, treatment duration, and lost to follow up explains some of the heterogeneity of treatment effects between studies. Community-based management improved treatment outcomes. A mix of interventions with DOTS-Plus throughout therapy and treatment duration > 18 months as well as strategies in place for lost to follow up and adverse events should be considered in MDR-TB and XDR-TB interventions, as they influenced positively, treatment success.

    The authors studied regional pulmonary function after treatment with bronchial plastic surgery for bronchial lesion from bronchial tuberculosis and with irradiation for bronchial lesion from carcinoma using positron emission tomography and Tc-MAA. Six patients with bronchial tuberculosis and 6 with bronchogenic carcinoma were examined. Two of the 6 bronchial tuberculosis patients were examined before and after surgery. In all 6 patients with bronchial tuberculosis, ventilation and alveolar volume were recovered with improvement of bronchial lesion. In 2 patients examined before and after surgery, lung function of the normal disease-free side became worse after surgery. This phenomenon was explained by the fact that the compensated pulmonary function of contra lateral lung due to decreased function of the diseased side returned to normal function with improvement of the diseased lung. On the other hand, the regional pulmonary function did not improve in 2 patients with main bronchial lesion from bronchogenic carcinoma, even if atelectasis of the diseased lung was improved by irradiation. However, the regional pulmonary function was improved with the recovery of bronchial obstruction in lobar atelectasis by carcinoma. The difference of the results depended on whether pulmonary blood flow disturbance existed or not. If pulmonary blood flow disturbance was severe, ventilatory function was not recovered due to the mechanism of maintaining the ventilation-perfusion equilibrium. (author)

    Although there are several studies reported on factors affecting tuberculosis (TB) treatment non-adherence, there is information gap on psychosocial and patients' perceptions aspects. Therefore, this study was aimed to investigate the effect of psychosocial factors and patients' perceptions on TB treatment non-adherence in Ethiopia. A cross sectional study was conducted in Addis Ababa from May to December, 2014. Thirty one health facilities were randomly selected and 698 TB patients, who had been on treatment, were enrolled consecutively using patient registration number. Structured questionnaire was used to collect data on demographics, knowledge, psychological distress, alcohol use, tobacco smoking and six HBM domains. Treatment adherence level was the main outcome variable, and it measured using visual analog scale. Statistical Package for Social Sciences version 20 was used for data analysis. Non-adherence level within last one month prior to the study was 19.5%. After controlling for all potential confounding variables, Antiretroviral Therapy (ART) status (Adjusted Odds Ratio (AOR) = 1.79, 95% Confidence interval (CI) (1.09 -2.95)), alcohol use (AOR = 2.11, 95% CI (1.33-3.37)), economic status (AOR = 0.53, 95% CI (0.33-0.82)), perceived barriers (AOR = 1.21, 95% CI (1.10-1.47)) and psychological distress (AOR = 1.83, 95% CI (1.47-2.29)) were independently associated with TB treatment non-adherence. ART status, economic status, alcohol use, perceived barrier and psychological distress are the major areas that need to be targeted with health promotion intervention to enhance TB treatment adherence.

    Full Text Available Background and objective: Istanbul has the highest incidence of tuberculosis (TB in Turkey. It is also the largest city, with considerable differences in quality of life across its urban regions. The aim of this study is to investigate the relationship between (i the diverse quality of life across specific urban regions, (ii TB incidence rates, inclusive of demographic and clinical characteristics of TB patients, and (iii adverse treatment outcomes. Methods: This retrospective study included 23,845 new TB patients (recorded in the National TB Registry between 2006 and 2010 in Istanbul. Thirty-nine urban districts of Istanbul were ranked into five groups on the basis of an urban quality of life index. Patient data were matched with these groups, and further categorized according to ‘age’, ‘sex’, ‘country of birth’ and ‘antibiotics resistance’. Adverse treatment outcomes and TB incidence rates were extracted from official records. Logistic regression, clustered analyses, 95% CI and p values (STATA were reported to describe the association between variables. Results: Six per cent of total cases had ‘at least one adverse treatment outcome’ (default 3.8%, failure 0.5%, death 1.7% in total cases. ‘An adverse treatment outcome’ was found to be associated with age OR (CI 95% (1.02 (1.01–1.03; ‘male sex’ 1.65 (1.28–2.12; ‘other country of birth’ 4.82 (3.05–7.62; 100,000 per ‘over 60’ insidence goups 1.61 (1.32-1.97, the lowest quality of life index 0.65 (0.47-0.83. Conclusions: Patients with high tuberculosis risk factors living in high incidence regions need to be closely monitored. Patients living in lower ranking regions are more likely to have ‘poor treatment outcomes’. Resumo: Contexto e objetivo: Istambul tem a mais elevada incidência de tuberculose (TB na Turquia.

    Full Text Available Background: In a high tuberculosis (TB burden county like India with different regional demography, knowledge about patient profile has a pivotal role in determining and identifying the factors associated with poor treatment outcomes among TB re-treatment cases. Aim: The aim was to describe the demography and clinical characteristics of TB re-treatment cases and to evaluate the factors associated with poor treatment outcomes among those patients. Settings and Design: A prospective longitudinal cohort study was carried out at chest medicine outdoor from February, 2011 to 2014 in a district medical college of West Bengal, India. Materials and Methods: Sputum smear positive re-treatment pulmonary TB patients attending our chest medicine outdoor during the 3 years study period were evaluated for demographic and clinical characteristics on the basis of previous treatment history and records at the beginning of the study. Patients were followed-up during the 8 months treatment period (Category II treatment regimen under Revised National TB Control Program. At the end of the study period, treatment outcomes were analyzed and factors associated with poor treatment outcomes were identified. Statistical Analysis: All variables were described by proportions, and differences between independent groups were compared using the Chi-square test and Fisher′s exact test, as applicable. Results: Among 74 patients, re-treatment was successful in 75.7% of relapse case, 66.7% of loss to follow-up cases and 53.8% of failure cases. Re-treatment failure was higher (38.5% in treatment failure cases compare to relapse cases (10.8% and initial loss to follow-up cases (16.7%. Young age, male, unmarried, employed who work outside appears to be the risk factors for loss to follow-up.

    Full Text Available Abstract Background Tuberculosis (TB is a global health concern. Inadequate case finding and case holding has been cited as major barrier to the control of TB. The TB literature is written almost entirely from a biomedical perspective, while recent studies show that it is imperative to understand lay perception to determine why people seek treatment and may stop taking treatment. The Eastern Cape is known as a province with high TB incidence, prevalence and with one of the worst cure rates of South Africa. Its inhabitants can be considered lay experts when it comes to TB. Therefore, we investigated knowledge, perceptions of (access to TB treatment and adherence to treatment among an Eastern Cape population. Methods An area-stratified sampling design was applied. A total of 1020 households were selected randomly in proportion to the total number of households in each neighbourhood. Results TB knowledge can be considered fairly good among this community. Respondents' perceptions suggest that stigma may influence TB patients' decision in health seeking behavior and adherence to TB treatment. A full 95% of those interviewed believe people with TB tend to hide their TB status out of fear of what others may say. Regression analyses revealed that in this population young and old, men and women and the lower and higher educated share the same attitudes and perceptions. Our findings are therefore likely to reflect the actual situation of TB patients in this population. Conclusions The lay experts' perceptions suggests that stigma appears to effect case holding and case finding. Future interventions should be directed at improving attitudes and perceptions to potentially reduce stigma. This requires a patient-centered approach to empower TB patients and active involvement in the development and implementation of stigma reduction programs.

    Full Text Available Introduction: The universal target under the Millennium Development Goals (MDGs is to reduce the worldwide burden of tuberculosis (TB 2015, and we wanted to evaluate development in TB control by assessment of the time trend in incidence and death rate in Tabriz, Iran. Methods: This was a retrospective trend analysis of the data have been recorded in East Azerbaijan State TB center during 10 years. Data were related to patients have been registered for treatment under the directly observed treatment, short-course (DOTS strategy from 2001 to 2011. Results: In total, 3283 TB patients were treated under DOTS strategy during 2001-2011. Males constituted 55.0% of subjects. The risk was the highest among the productive age group (15-44 years. About 61.0% of cases had pulmonary, and 78.0% of pulmonary TB patients were found to be the sputum smear positive than 46.0% of them were new sputum smear positive, and 2.0% of them were relapse. On average, for sputum smear positive, TB cases from 2005 to 2011; the treatment success rate was 87.3%; the cure rate was 80.2%; the treatment failure rate was 0.5% and death rate was 10.3%. In general, the TB incidence rate for all TB cases was decreased from 11.9-8.1 a 100000 population and the smear-positive pulmonary TB incidence rate were decreased from 4.7 to 4.1 a 100000 population in eastern Azerbaijan province during 2001-2011. Conclusion: In general, we had a decrease in the incidence rate for all of TB cases. In addition, we had a fall in cure rate and had an increase in drug side effects rate in this year that can be because of elevated old people ratio and high death rate by other indirect causes and lack of regular visits and medications taking according to the treatment protocol.

  10. Second line drug susceptibility testing to inform the treatment of rifampin-resistant tuberculosis: a quantitative perspective

    2017-03-01

    Full Text Available Treatment failure and resistance amplification are common among patients with rifampin-resistant tuberculosis (TB. Drug susceptibility testing (DST for second-line drugs is recommended for these patients, but logistical difficulties have impeded widespread implementation of second-line DST in many settings. To provide a quantitative perspective on the decision to scale up second-line DST, we synthesize literature on the prevalence of second-line drug resistance, the expected clinical and epidemiologic benefits of using second-line DST to ensure that patients with rifampin-resistant TB receive effective regimens, and the costs of implementing (or not implementing second-line DST for all individuals diagnosed with rifampin-resistant TB. We conclude that, in most settings, second-line DST could substantially improve treatment outcomes for patients with rifampin-resistant TB, reduce transmission of drug-resistant TB, prevent amplification of drug resistance, and be affordable or even cost-saving. Given the large investment made in each patient treated for rifampin-resistant TB, these payoffs would come at relatively small incremental cost. These anticipated benefits likely justify addressing the real challenges faced in implementing second-line DST in most high-burden settings.

    New and repurposed antituberculosis drugs are urgently needed to more safely and effectively treat multidrug-resistant (MDR) tuberculosis (TB) in children. Multiple challenges limit timely access to new MDR-TB treatments in children. Areas covered: Diagnosis of MDR-TB in children remains a barrier, with few children with MDR-TB diagnosed and treated. Other barriers to timely access to new and repurposed drugs are discussed, and include delayed initiation of paediatric trials, limited funding for paediatric drug development, fragmented regulatory systems and operational challenges. The status of access to current repurposed and novel drugs is presented. Expert commentary: More timely initiation of paediatric trials is needed and paediatric work should happen and be funded in parallel with each phase of adult trials. Better quality data, increased regulator resources and expertise, harmonization of regulatory requirements across borders/organisations and registration fee waivers would improve registration timelines. Improved diagnosis, recording and reporting will establish better demand. Improved systems for procurement and supply chain management would reduce in-country operational barriers to getting medications to children. The challenges must be addressed to ensure timely and equitable access to new drugs and regimens that are urgently needed for effective, safe and shorter treatment of children with MDR-TB.

  12. Targeting phenotypically tolerant Mycobacterium tuberculosis

    2016-01-01

    While the immune system is credited with averting tuberculosis in billions of individuals exposed to Mycobacterium tuberculosis, the immune system is also culpable for tempering the ability of antibiotics to deliver swift and durable cure of disease. In individuals afflicted with tuberculosis, host immunity produces diverse microenvironmental niches that support suboptimal growth, or complete growth arrest, of M. tuberculosis. The physiological state of nonreplication in bacteria is associated with phenotypic drug tolerance. Many of these host microenvironments, when modeled in vitro by carbon starvation, complete nutrient starvation, stationary phase, acidic pH, reactive nitrogen intermediates, hypoxia, biofilms, and withholding streptomycin from the streptomycin-addicted strain SS18b, render M. tuberculosis profoundly tolerant to many of the antibiotics that are given to tuberculosis patients in a clinical setting. Targeting nonreplicating persisters is anticipated to reduce the duration of antibiotic treatment and rate of post-treatment relapse. Some promising drugs to treat tuberculosis, such as rifampicin and bedaquiline, only kill nonreplicating M. tuberculosis in vitro at concentrations far greater than their minimal inhibitory concentrations against replicating bacilli. There is an urgent demand to identify which of the currently used antibiotics, and which of the molecules in academic and corporate screening collections, have potent bactericidal action on nonreplicating M. tuberculosis. With this goal, we review methods of high throughput screening to target nonreplicating M. tuberculosis and methods to progress candidate molecules. A classification based on structures and putative targets of molecules that have been reported to kill nonreplicating M. tuberculosis revealed a rich diversity in pharmacophores. However, few of these compounds were tested under conditions that would exclude the impact of adsorbed compound acting during the recovery phase of

    Full Text Available Background: The risk of short-term death for treatment naive patients dually infected with Mycobacterium tuberculosis and HIV may be reduced by early anti-retroviral therapy. Of those dying, mechanisms responsible for fatal outcomes are unclear. We hypothesized that greater malnutrition and/or inflammation when initiating treatment are associated with an increased risk for death. Methods: We utilized a retrospective case-cohort design among participants of the ACTG A5221 study who had baseline CD4 < 50 cells/mm3. The case-cohort sample consisted of 51 randomly selected participants, whose stored plasma was tested for C-reactive protein, cytokines, chemokines, and nutritional markers. Cox proportional hazards models were used to assess the association of nutritional, inflammatory, and immunomodulatory markers for survival. Results: The case-cohort sample was similar to the 282 participants within the parent cohort with CD4 < 50 cells/mm3. In the case cohort, 7 (14% had BMI < 16.5 (kg/m2 and 17 (33% had BMI 16.5-18.5(kg/m2. Risk of death was increased per 1 IQR width higher of log10 transformed level of C-reactive protein (adjusted hazard ratio (aHR = 3.42 [95% CI = 1.33-8.80],P = 0.011, interferon gamma (aHR = 2.46 [CI = 1.02-5.90], P = 0.044, MCP-3 (3.67 [CI = 1.08-12.42], P = 0.037, and with IL-15 (aHR = 2.75 [CI = 1.08-6.98], P = 0.033 and IL-17 (aHR = 3.99 [CI = -1.06-15.07], P = 0.041. BMI, albumin, hemoglobin, and leptin levels were not associated with risk of death.

Risk of death was associated with significant increases in markers of global inflammation along with soluble biomarkers of innate and adaptive immunity.
