Major differences in organization and availability of health care and medicines for HIV/TB coinfected patients across Europe

Improving healthcare for patients with HIV, tuberculosis and hepatitis C in eastern Europe: a review of current challenges and important next steps

OBJECTIVES

In some eastern European countries, serious challenges exist to meet the HIV-, tuberculosis (TB)- and hepatitis-related target of the United Nations Sustainable Development Goals. Some of the highest incidence rates for HIV and the highest proportion of multi-drug-resistant (MDR) tuberculosis worldwide are found in the region. The purpose of this article is to review the challenges and important next steps to improve healthcare for people living with TB, HIV and hepatitis C (HCV) in eastern Europe.

METHODS

References for this narrative review were identified through systematic searches of PubMed using pre-idientified key word for articles published in English from January 2000 to August 2020. After screening of titles and abstracts 37 articles were identified as relevant for this review. Thirty-eight further articles and sources were identified through searches in the authors' personal files and in Google Scholar.

RESULTS

Up to 50% of HIV/MDR-TB-coinfected individuals in the region die within 2 years of treatment initiation. Antiretroviral therapy (ART) coverage for people living with HIV (PLHIV) and the proportion virological suppressed are far below the UNAIDS 90% targets. In theory, access to various diagnostic tests and treatment of drug-resistant TB exists, but real-life data point towards inadequate testing and treatment. New treatments could provide elimination of viral HCV in high-risk populations but few countries have national programmes.

CONCLUSION

Some eastern European countries face serious challenges to achieve the sustainable development goal-related target of 3.3 by 2030, among others, to end the epidemics of AIDS and tuberculosis. Better integration of healthcare systems, standardization of health care, unrestricted substitution therapy for all people who inject drugs, widespread access to drug susceptibility testing, affordable medicines and a sufficiently sized, well-trained health workforce could address some of those challenges.

Tuberculosis Drug Susceptibility, Treatment, and Outcomes for Belarusian HIV-Positive Patients with Tuberculosis: Results from a National and International Laboratory

BACKGROUND

To cure drug-resistant (DR) tuberculosis (TB), the antituberculous treatment should be guided by Mycobacterium tuberculosis drug-susceptibility testing (DST). In this study, we compared conventional DST performed in Minsk, Belarus, a TB DR high-burden country, with extensive geno- and phenotypic analyses performed at the WHO TB Supranational Reference Laboratory in Copenhagen, Denmark, for TB/HIV coinfected patients. Subsequently, DST results were related to treatment regimen and outcome.

METHODS

Thirty TB/HIV coinfected patients from Minsk were included and descriptive statistics applied.

RESULTS

Based on results from Minsk, 10 (33%) TB/HIV patients had drug-sensitive TB. Two (7%) had isoniazid monoresistant TB, 8 (27%) had multidrug-resistant (MDR) TB, 5 (17%) preextensive drug-resistant (preXDR) TB, and 5 (17%) had extensive drug-resistant (XDR) TB. For the first-line drugs rifampicin and isoniazid, there was DST agreement between Minsk and Copenhagen for 90% patients. For the second-line anti-TB drugs, discrepancies were more pronounced. For 14 (47%) patients, there were disagreements for at least one drug, and 4 (13%) patients were classified as having MDR-TB in Minsk but were classified as having preXDR-TB based on DST results in Copenhagen. Initially, all patients received standard anti-TB treatment with rifampicin, isoniazid, pyrazinamide, and ethambutol. However, this was only suitable for 40% of the patients based on DST. On average, DR-TB patients were changed to 4 (IQR 3-5) active drugs after 1.5 months (IQR 1-2). After treatment adjustment, the treatment duration was 8 months (IQR 2-11). Four (22%) patients with DR-TB received treatment for >18 months. In total, sixteen (53%) patients died during 24 months of follow-up.

CONCLUSIONS

We found high concordance for rifampicin and isoniazid DST between the Minsk and Copenhagen laboratories, whereas discrepancies for second-line drugs were more pronounced. For patients with DR-TB, treatment was often insufficient and relevant adjustments delayed. This example from Minsk, Belarus, underlines two crucial points in the management of DR-TB: the urgent need for implementation of rapid molecular DSTs and availability of second-line drugs in all DR-TB high-burden settings. Carefully designed individualized treatment regimens in accordance with DST patterns will likely improve patients' outcome and reduce transmission with drug-resistant Mycobacterium tuberculosis strains.

Healthcare delivery for HIV-positive people with tuberculosis in Europe

BACKGROUND

In a 2013 survey, we reported distinct discrepancies in delivery of tuberculosis (TB) and HIV services in eastern Europe (EE) vs. western Europe (WE).

OBJECTIVES

To verify the differences in TB and HIV services in EE vs. WE.

METHODS

Twenty-three sites completed a survey in 2018 (EE, 14; WE, nine; 88% response rate). Results were compared across as well as within the two regions. When possible, results were compared with the 2013 survey.

RESULTS

Delivery of healthcare was significantly less integrated in EE: provision of TB and HIV services at one site (36% in EE vs. 89% in WE; P = 0.034), and continued TB follow-up in one location (42% vs. 100%; P = 0.007). Although access to TB diagnostics, standard TB and HIV drugs was generally good, fewer sites in EE reported unlimited access to rifabutin/multi-drug-resistant TB (MDR-TB) drugs, HIV integrase inhibitors and opioid substitution therapy (OST). Compared with 2013, routine usage of GeneXpert was more common in EE in 2018 (54% vs. 92%; P = 0.073), as was access to moxifloxacin (46% vs. 91%; P = 0.033), linezolid (31% vs. 64%; P = 0.217), and bedaquiline (0% vs. 25%; P = 0.217). Integration of TB and HIV services (46% vs. 39%; P = 1.000) and provision of OST to patients with opioid dependency (54% vs. 46%; P = 0.695) remained unchanged.

CONCLUSION

Delivery of TB and HIV healthcare, including integration of TB and HIV care and access to MDR-TB drugs, still differs between WE and EE, as well as between individual EE sites.

"East" in Europe-Health Dimension through the Lens of the UK Daily Mail and Statistical Facts

The study concerns the relationship between health and geopolitics in the United Kingdom (UK). To demonstrate this relationship, we examined the subject and tone of articles published in the popular media (on the example of tabloid the Daily Mail) in 2006–2020 concerning health and medical care, and the health and health care practice of Eastern European immigrants belonging to and not belonging to the European Union (EU). There was an increase in media criticism of the behaviour of immigrants in the years 2014–2017, in the period around the referendum in favour of the UK leaving the EU (Brexit). Attention was drawn to the media’s use of a Belief in a Zero-Sum Game (BZSG) narrative at that time. On both sides, “hosts” and the “guests”, a progressive anomy process was observed, degrading the behaviour of individuals and social groups.

Collaborative tuberculosis/HIV activities in the European Region

INTRODUCTION

An estimated 12% of tuberculosis (TB) patients are co-infected with HIV in the World Health Organization European Region (the Region). Reducing morbidity and mortality from HIV-associated TB requires strong collaboration between TB and HIV services at all levels with integrated people-centred models of care.

METHODS

We collected information on the current models of integration of TB and HIV services in the Region via a comprehensive survey among the TB and HIV National Focal Points, and identified challenges and opportunities.

RESULTS

47 out of 55 (85%) countries responded. HIV testing in all TB patients and screening for active TB in all people living with HIV (PLHIV) was recommended in 40 (85%) and 34 (72%) countries, respectively. 30 (64%) countries recommended latent TB infection (LTBI) screening in all PLHIV, while 13 (28%) had a selective approach and four (9%) did not recommend LTBI screening. In most countries, testing for HIV and screening for active TB and LTBI was done by the specialist treating the patient, i.e. TB patients were tested for HIV by a TB specialist in 42 (89%) countries and PLHIV were screened for active TB by an HIV specialist in 34 (72%) countries.

CONCLUSIONS

TB and HIV care are well integrated in policies of especially high TB and high HIV burden countries; however, implementation needs to be improved. Continuous monitoring of TB and HIV services integration enables assessing the quality of TB/HIV care and to identify where further improvements are needed.

New possibilities to diagnose pulmonary tuberculosis at a pulmonology inpatient department

The aim of the study was to investigate new methods for pulmonary tuberculosis (TB) detection at a pulmonology inpatient department.

Methods. Pulmonary TB cases (n = 49) newly diagnosed at a pulmonology department of a hospital were involved in the study; among them, 69.4% of patients were infected with human immunodeficiency virus (HIV). All patients were asked if he/she had previously contacted with other TB patients, and if he/she was diagnosed with TB previously. The patients were also about family history. Posteroanterior and lateral chest X-ray and laboratory analyses were performed in all patients. Mycobacteria tuberculosis (MBT) were searched using smear microscopy, GeneXpert MTB/RIF molecular method and culturing (BACTEC MGIT) of sputum and bronchoalveolar lavage fluid (BALF) obtained during bronchoscopy. Patients with positive results only were included in the analysis in order to investigate and to compare diagnostic value of the methods.

Results. Questioning patients at admission was useful to diagnose TB in 4% of patients. Sputum smears were positive in 12 patients (27.3%). BALF was obtained in 18 patients (36.7%); among them, MBT was identified in 52 (5%). Molecular testing was positive in all 49 patients (100%); among them, BACTEC MGIT culturing yielded MBT in 48 patients (97.9%). In patients with negative sputum smears during the first 3 days after admission, GeneXpert required 10.4 ± 5.3 days.

Conclusion. GeneXpert method was highly useful to diagnose TB and was comparable with BACTEC. Routine sputum and BALF smear microscopy was significantly less rapid and less sensitive method. The diagnostic accuracy could be increased with the use of molecular methods in patients with negative sputum smears obtained at a general hospital. Therefore, molecular methods could be used in patients highly suspected for TB. 

Treatment outcomes and antiretroviral uptake in multidrug-resistant tuberculosis and HIV co-infected patients in Sub Saharan Africa: a systematic review and meta-analysis

BACKGROUND

Multidrug-resistant tuberculosis (MDR-TB) in HIV endemic settings is a major threat to public health. MDR-TB is a substantial and underreported problem in Sub-Saharan Africa (SSA), with recognised cases projected to increase with advancement in diagnostic technology. There is paucity of review evidence on treatment outcomes and antiretroviral (ART) uptake among MDR-TB patients with HIV in SSA. To address this gap a review of treatment outcomes in HIV patients co-infected with MDR-TB in the SSA region was undertaken.

METHODS

Three databases (Medline, Web of Science, CINHAL), Union on Lung Heath conference proceedings and grey literature were searched for publications between January 2004 and May 2018. Records were assessed for eligibility and data extracted. Random effect meta-analysis was conducted using STATA and Cochrane's review manager.

RESULTS

A total of 271 publications were identified of which nine fulfilled the inclusion criteria. Data was collected from 3368 MDR-TB and HIV co-infected patients from four SSA countries; South Africa (6), Lesotho (1), Botswana (1) and Ethiopia (1). The most common outcome was cure (34.9% cured in the pooled analysis), this was followed by death (18.1% in pooled analysis). ART uptake was high, at 83% in the pooled analysis. Cure ranged from 28.6 to 54.7% among patients on ART and from 22.2 to 57.7%  among those not on ART medication. MDR-TB and HIV co-infected patients were less likely to be successfully treated than HIV negative MDR-TB patients (Risk Ratio = 0.87, 95% CI 0.97, 0.96).

CONCLUSION

Treatment outcomes for MDR-TB and HIV co-infected patients do not vary widely from those reported globally. However, treatment success was lower among HIV positive MDR-TB patients compared to HIV negative MDR-TB patients. Prompt antiretroviral initiation and interventions to improve treatment adherence are necessary.

High Yield of Active Tuberculosis Case Finding Among HIV-Infected Patients Using Xpert MTB/RIF Testing

Objective

Conduct an active case finding study in Tbilisi, Georgia, for pulmonary tuberculosis (TB) among people living with HIV (PLWH).

Methods

Newly diagnosed HIV patients were assessed for symptoms and asked to submit sputum samples for smear microscopy, culture, and molecular diagnostic testing (Xpert MTB/RIF).

Results

Among 276 PLWH, 131 agreed to participate and 103 submitted sputum samples. Most participants were male (70%) and mean age of 43 years. There were high rates of a positive hepatitis C virus (HCV) antibody test (46%) and the median CD4 count was 122 cells/mm³. A total of 15 (11.5%) persons were diagnosed with pulmonary TB, including 1 each with multidrug-resistant and isoniazid-resistant disease. Twelve had a positive culture for Mycobacterium tuberculosis and Xpert TB/RIF assay, and 4 had positive smear microscopy. Patients with pulmonary TB were more likely to use injection drugs (67% vs 36%, P = .02) and have a positive HCV antibody (73% vs 42%, P = .02). The presence and absence of any TB symptom had a sensitivity and negative predictive value for TB of 93% and 98%, respectively.

Conclusion

Our findings highlight the high prevalence of TB among newly diagnosed HIV-infected patients in an area with high rates of drug-resistant TB and the utility of an active case finding strategy for TB diagnosis.

Management of MDR-TB in HIV co-infected patients in Eastern Europe: Results from the TB:HIV study

OBJECTIVES

Mortality among HIV patients with tuberculosis (TB) remains high in Eastern Europe (EE), but details of TB and HIV management remain scarce.

METHODS

In this prospective study, we describe the TB treatment regimens of patients with multi-drug resistant (MDR) TB and use of antiretroviral therapy (ART).

RESULTS

A total of 105 HIV-positive patients had MDR-TB (including 33 with extensive drug resistance) and 130 pan-susceptible TB. Adequate initial TB treatment was provided for 8% of patients with MDR-TB compared with 80% of those with pan-susceptible TB. By twelve months, an estimated 57.3% (95%CI 41.5-74.1) of MDR-TB patients had started adequate treatment. While 67% received ART, HIV-RNA suppression was demonstrated in only 23%.

CONCLUSIONS

Our results show that internationally recommended MDR-TB treatment regimens were infrequently used and that ART use and viral suppression was well below the target of 90%, reflecting the challenging patient population and the environment in which health care is provided. Urgent improvement of management of patients with TB/HIV in EE, in particular for those with MDR-TB, is needed and includes widespread access to rapid TB diagnostics, better access to and use of second-line TB drugs, timely ART initiation with viral load monitoring, and integration of TB/HIV care.

One-year mortality of HIV-positive patients treated for rifampicin- and isoniazid-susceptible tuberculosis in Eastern Europe, Western Europe, and Latin America

OBJECTIVES

The high mortality among HIV/tuberculosis (TB) coinfected patients in Eastern Europe is partly explained by the high prevalence of drug-resistant TB. It remains unclear whether outcomes of HIV/TB patients with rifampicin/isoniazid-susceptible TB in Eastern Europe differ from those in Western Europe or Latin America.

METHODS

One-year mortality of HIV-positive patients with rifampicin/isoniazid-susceptible TB in Eastern Europe, Western Europe, and Latin America was analysed and compared in a prospective observational cohort study. Factors associated with death were analysed using Cox regression modelsRESULTS:: Three hundred and forty-one patients were included (Eastern Europe 127, Western Europe 165, Latin America 49). Proportions of patients with disseminated TB (50, 58, 59%) and initiating rifampicin + isoniazid + pyrazinamide-based treatment (93, 94, 94%) were similar in Eastern Europe, Western Europe, and Latin America respectively, whereas receipt of antiretroviral therapy at baseline and after 12 months was lower in Eastern Europe (17, 39, 39%, and 69, 94, 89%). The 1-year probability of death was 16% (95% confidence interval 11-24%) in Eastern Europe, vs. 4% (2-9%) in Western Europe and 9% (3-21%) in Latin America; P < 0.0001. After adjustment for IDU, CD4 cell count and receipt of antiretroviral therapy, those residing in Eastern Europe were at nearly 3-fold increased risk of death compared with those in Western Europe/Latin America (aHR 2.79 (1.15-6.76); P = 0.023).

CONCLUSIONS

Despite comparable use of recommended anti-TB treatment, mortality of patients with rifampicin/isoniazid-susceptible TB remained higher in Eastern Europe when compared with Western Europe/Latin America. The high mortality in Eastern Europe was only partially explained by IDU, use of ART and CD4 cell count. These results call for improvement of care for TB/HIV patients in Eastern Europe.

Tuberculosis and HIV coinfection in Europe: looking at one reality from two angles

Objective:

To better understand the epidemiology of tuberculosis (TB)/HIV coinfection in the European Union (EU) and European Economic Area (EEA) for planning of prevention and control measures.

Design:

Analysis of surveillance data.

Methods:

We performed an analysis of the 2014 TB and AIDS data to assess the burden of TB/HIV coinfection and we applied multivariable logistic regression to evaluate predictors for coinfection.

Results:

Twenty-one of 31 EU/EEA countries reported HIV testing results for 64.6% of the 32 892 notified TB cases. Of those, 1051 (4.9%) were reported as HIV-positive. Males [adjusted odds ratio (aOR) 1.25; 95% confidence interval (CI) 1.07–1.46] and those in age group 25–44 years were more frequently coinfected. TB cases originating from the WHO African region had the highest proportion of coinfection (aOR 3.28 versus origin in EU/EEA; 95% CI 2.35–4.57). TB treatment was completed successfully by 57.9% of HIV-positive TB cases and 83.5% of HIV-negative cases. In 2014, 3863 cases of AIDS were reported by 29 EU/EEA countries; 691 (17.9%) of these cases presented with TB as an AIDS-defining illness. Persons who had acquired HIV through injecting drug use had higher odds of TB as an AIDS-defining illness (aOR 1.78 versus heterosexual route of transmission; 95% CI 1.37–2.32).

Conclusion:

TB/HIV coinfection is a substantial problem in the EU/EEA. The occurrence of TB in HIV-positive cases and the low TB treatment success rate suggest that international guidelines for prevention and treatment of TB in HIV-infected adults need to be better implemented.

Euroguidelines in Central and Eastern Europe (ECEE) conference and the Warsaw Declaration - a comprehensive meeting report

OBJECTIVES

The objective of this paper is to summarize the outcomes of the Euroguidelines in Central and Eastern Europe (ECEE) conference held in Warsaw in February 2016. The main aim of this conference was to facilitate a discussion on European AIDS Clinical Society (EACS) guidelines implementation across the region and neighbouring countries and to present the current obstacles in benchmarking HIV care in Europe.

METHODS

During a 2-day meeting, there were country-based presentations using a predefined template so as to make the data comparable and focus the discussion. Areas covered were country epidemiology, surveillance, national strategy for treatment and prevention, standards of care, access to care and treatment availability. Each participant filled in a questionnaire investigating HIV guidelines usage per country.

RESULTS

In total, 16 Central and Eastern Europe (CEE) and neighbouring countries were represented at the conference: Albania, Armenia, Belarus, Croatia, Czech Republic, Estonia, Georgia, Hungary, Lithuania, Moldova, Poland, Romania, Russia, Serbia, Slovakia and Turkey. EACS guidelines version 7.1 were used in 14 (87%) countries. In 11 (69%) countries, national guidelines were available, of which eight had been recently updated. Half of the countries declared that they use World Health Organization (WHO) and Department of Health and Human Services (DHHS) guidelines, over one-third the European Centre for Disease Prevention and Control (ECDC) HIV testing guidelines and one in five the International Antiviral Society-USA (IAS-USA) Panel guidelines from 2012.

CONCLUSIONS

Participants declared their will to promote the widespread use of EACS guidelines for HIV infection in the CEE region and neighbouring countries by signing the Warsaw Declaration. They also emphasized the need to increase publishing of data from national cohorts in that region.

Disparities in HIV clinic care across Europe: findings from the EuroSIDA clinic survey

BACKGROUND

Although advances in HIV medicine have yielded increasingly better treatment outcomes in recent years, HIV-positive people with access to antiretroviral therapy (ART) still face complex health challenges. The EuroSIDA Study Group surveyed its clinics to explore regional differences in clinic services.

METHODS

The EuroSIDA study is a prospective observational cohort study that began enrolling patients in 1994. In early 2014, we conducted a 59-item survey of the 98 then-active EuroSIDA clinics. The survey covered HIV clinical care and other aspects of patient care. The EuroSIDA East Europe study region (Belarus, Estonia, Lithuania, the Russian Federation and Ukraine) was compared to a "non-East Europe" study region comprised of all other EuroSIDA countries.

RESULTS

A larger proportion of clinics in the East Europe group reported deferring ART in asymptomatic patients until the CD4 cell count dropped below 350 cells/mm(3) (75 % versus 25 %, p = 0.0032). Considerably smaller proportions of East Europe clinics reported that resistance testing was provided before ART initiation (17 % versus 86 %, p < 0.0001) and that it was provided upon treatment failure (58 % versus 90 %, p = 0.0040). Only 33 % of East Europe clinics reported providing hepatitis B vaccination, compared to 88 % of other clinics (p < 0.0001). Only 50 % of East Europe clinics reported having access to direct-acting antivirals for hepatitis C treatment, compared to 89 % of other clinics (p = 0.0036). There was significantly less tuberculosis/HIV treatment integration in the East Europe group (27 % versus 84 % p < 0.0001) as well as significantly less screening for cardiovascular disease (58 % versus 90 %, p = 0.014); tobacco use (50 % versus 93 %, p < 0.0001); alcohol consumption (50 % versus 93 %, p < 0.0001); and drug use (58 % versus 87 %, p = 0.029).

CONCLUSIONS

Study findings demonstrate how specific features of HIV clinics differ across Europe. Significantly more East Europe clinics deferred ART in asymptomatic patients for longer, and significantly fewer East Europe clinics provided resistance testing before initiating ART or upon ART failure. The East Europe group of clinics also differed in regard to hepatitis B vaccination, direct-acting antiviral access, tuberculosis/HIV treatment integration and screening for other health issues. There is a need for further research to guide setting-specific decision-making regarding the optimal array of services at HIV clinics in Europe and worldwide.

Tuberculosis-related mortality in people living with HIV in Europe and Latin America: an international cohort study

BACKGROUND

Management of tuberculosis in patients with HIV in eastern Europe is complicated by the high prevalence of multidrug-resistant tuberculosis, low rates of drug susceptibility testing, and poor access to antiretroviral therapy (ART). We report 1 year mortality estimates from a multiregional (eastern Europe, western Europe, and Latin America) prospective cohort study: the TB:HIV study.

METHODS

Consecutive HIV-positive patients aged 16 years or older with a diagnosis of tuberculosis between Jan 1, 2011, and Dec 31, 2013, were enrolled from 62 HIV and tuberculosis clinics in 19 countries in eastern Europe, western Europe, and Latin America. The primary endpoint was death within 12 months after starting tuberculosis treatment; all deaths were classified according to whether or not they were tuberculosis related. Follow-up was either until death, the final visit, or 12 months after baseline, whichever occurred first. Risk factors for all-cause and tuberculosis-related deaths were assessed using Kaplan-Meier estimates and Cox models.

FINDINGS

Of 1406 patients (834 in eastern Europe, 317 in western Europe, and 255 in Latin America), 264 (19%) died within 12 months. 188 (71%) of these deaths were tuberculosis related. The probability of all-cause death was 29% (95% CI 26-32) in eastern Europe, 4% (3-7) in western Europe, and 11% (8-16) in Latin America (p<0·0001) and the corresponding probabilities of tuberculosis-related death were 23% (20-26), 1% (0-3), and 4% (2-8), respectively (p<0·0001). Patients receiving care outside eastern Europe had a 77% decreased risk of death: adjusted hazard ratio (aHR) 0·23 (95% CI 0·16-0·31). In eastern Europe, compared with patients who started a regimen with at least three active antituberculosis drugs, those who started fewer than three active antituberculosis drugs were at a higher risk of tuberculosis-related death (aHR 3·17; 95% CI 1·83-5·49) as were those who did not have baseline drug-susceptibility tests (2·24; 1·31-3·83). Other prognostic factors for increased tuberculosis-related mortality were disseminated tuberculosis and a low CD4 cell count. 18% of patients were receiving ART at tuberculosis diagnosis in eastern Europe compared with 44% in western Europe and 39% in Latin America (p<0·0001); 12 months later the proportions were 67% in eastern Europe, 92% in western Europe, and 85% in Latin America (p<0·0001).

INTERPRETATION

Patients with HIV and tuberculosis in eastern Europe have a risk of death nearly four-times higher than that in patients from western Europe and Latin America. This increased mortality rate is associated with modifiable risk factors such as lack of drug susceptibility testing and suboptimal initial antituberculosis treatment in settings with a high prevalence of drug resistance. Urgent action is needed to improve tuberculosis care for patients living with HIV in eastern Europe.

Major Challenges in Clinical Management of TB/HIV Coinfected Patients in Eastern Europe Compared with Western Europe and Latin America

OBJECTIVES

Rates of TB/HIV coinfection and multi-drug resistant (MDR)-TB are increasing in Eastern Europe (EE). We aimed to study clinical characteristics, factors associated with MDR-TB and predicted activity of empiric anti-TB treatment at time of TB diagnosis among TB/HIV coinfected patients in EE, Western Europe (WE) and Latin America (LA).

DESIGN AND METHODS

Between January 1, 2011, and December 31, 2013, 1413 TB/HIV patients (62 clinics in 19 countries in EE, WE, Southern Europe (SE), and LA) were enrolled.

RESULTS

Significant differences were observed between EE (N = 844), WE (N = 152), SE (N = 164), and LA (N = 253) in the proportion of patients with a definite TB diagnosis (47%, 71%, 72% and 40%, p<0.0001), MDR-TB (40%, 5%, 3% and 15%, p<0.0001), and use of combination antiretroviral therapy (cART) (17%, 40%, 44% and 35%, p<0.0001). Injecting drug use (adjusted OR (aOR) = 2.03 (95% CI 1.00-4.09), prior anti-TB treatment (3.42 (1.88-6.22)), and living in EE (7.19 (3.28-15.78)) were associated with MDR-TB. Among 585 patients with drug susceptibility test (DST) results, the empiric (i.e. without knowledge of the DST results) anti-TB treatment included ≥3 active drugs in 66% of participants in EE compared with 90-96% in other regions (p<0.0001).

CONCLUSIONS

In EE, TB/HIV patients were less likely to receive a definite TB diagnosis, more likely to house MDR-TB and commonly received empiric anti-TB treatment with reduced activity. Improved management of TB/HIV patients in EE requires better access to TB diagnostics including DSTs, empiric anti-TB therapy directed at both susceptible and MDR-TB, and more widespread use of cART.
