A retrospective cohort analysis of treatment outcomes of patients with tuberculosis who used substances in Tel Aviv, Israel.

AIMS: To outline the demographic, clinical, laboratory characteristics, and treatment outcomes of tuberculosis (TB) patients who used substances. METHODS: This retrospective cohort study compared 50 TB patients who used substances with a matched random sample of 100 TB patients who did not use substances between 2007 and 2017. Treatment failure was defined as a sputum smear or culture that tested positive after 5 months of treatment, loss to follow-up, unevaluated patients, or death. RESULTS: TB patients who used substances were typically younger, experienced homelessness, smokers, and had fewer chronic diseases than those who did not use substances. They also were hospitalized for longer periods, their treatment durations were longer, had higher rates of multidrug resistant strains, increased rates of treatment failure, and higher mortality. Individuals whose treatment failed predominantly originated from the former Soviet Union, experienced homelessness, and had chronic diseases compared with those whose treatment was successful. In the multivariate analysis, homelessness [odds ratios (OR) = 6.7], chronic diseases (OR = 12.4), and substance use (OR = 4.0) were predictors of treatment failures. CONCLUSIONS: TB patients who used substances were more likely to have treatment failure. Targeted interventions, including early diagnosis and enhanced support during treatment, are essential to achieve treatment success in this vulnerable population, in addition to TB-alcohol/drug collaborative activities.

Tuberculosis outbreak in an immigrant reception center in Israel: a clinical and epidemiologic perspective.

Tuberculosis (TB) outbreaks in congregate settings pose a public health concern and a clinical challenge. We report a TB outbreak involving 6 cases of active TB among 28 recent Ethiopian immigrants (EIs) in an immigrant reception center in Israel. The outbreak erupted several weeks after a meticulous pre-immigration TB screening of this group. All five culture-positive TB patients were infected with the CAS1_DELHI family, SIT 25 strain. Pulmonary involvement manifested as only a persistent cough without systemic symptoms. This outbreak occurred because of miscommunication among healthcare staff and between healthcare staff and the EI index case. It was fuelled by the staff ignorance of the social bonds within the group, and the sluggish once-monthly schedule of the on-site TB clinic operated at the reception center, which further lacked radiography facilities. This outbreak highlights the challenges of screening for active TB among immigrants and hard to reach groups.

Same but different: tuberculosis treatment and care among migrants from different countries of origin in Israel.

INTRODUCTION: Israel hosts documented labor migrants (DLM), and recently also undocumented migrants (UDM), mostly from Horn of Africa. This study aims to compare treatment outcomes and other clinical aspects between a sample of 154 DLM and 113 UDM who were treated in two tuberculosis clinics between 2005 and 2010. RESULTS AND DISCUSSION: Compared to DLM, UDM were younger males, stayed in Israel for shorter periods, had lower coverage of medical insurance, were less likely to be employed, and had greater difficulties in communication with the medical staff. UDM were more likely to demonstrate tuberculosis-related symptoms than DLM, were more commonly diagnosed with pulmonary TB, and had shorter patient and system delays and their treatment success rate was better than DLM, who were more likely to be transferred out. CONCLUSION: UDM achieved better treatment outcomes, as they were screened upon entry and treatment was initiated in detention, while DLM were diagnosed in the community and may have felt more secure to abandon treatment.

Indolent pneumonia in a pregnant recent immigrant from Ethiopia: think TB.

Time delay to tuberculosis (TB) diagnosis remains a public health concern. In pregnancy, early TB diagnosis is challenging and acquires further significance due to the risk of infection of the newborn as well as others in the maternity setting. We report a delay of 12 weeks in the diagnosis of TB in a pregnant recent immigrant from Ethiopia to Israel. Contact investigation revealed pulmonary TB in her two daughters aged four and seven years. We discuss the reasons for this delay in diagnosis, how a more timely diagnosis might have been made, and the dilemma of initiating treatment in unconfirmed TB.

Tuberculosis incidence in HIV/AIDS patients in Israel, 1983-2010.

OBJECTIVES: People living with HIV/AIDS (PLWHA) who develop tuberculosis disease are at greater mortality-risk. This study aimed to assess tuberculosis disease incidence among all PLWHA in Israel and identify populations at high-risk for developing tuberculosis. DESIGN AND METHODS: Retrospective cohort-study based on the National HIV and Tuberculosis Registries, which were cross-matched and followed for the last 28-years. PLWHA who developed tuberculosis were compared to those who did not by the Cox-proportional analysis to generate hazard-ratios, and survival-analysis was performed by Log-Rank test. RESULTS: Of all the 6579 PLWHA reported between 1983 and 2010, corresponding to 55737 person-years, 384 (5.8%) developed tuberculosis. Of those, 14 were Israeli-born and 370 were non-Israeli born. The overall tuberculosis incidence-density was 6.9 cases/1000 person-years (95% CI 1.8-12.0). The cumulative tuberculosis-incidence among PLWHA in 2010 was 586 times higher than in HIV-negative individuals (3400 and 5.8 cases per 100000 population, respectively). Higher hazard-ratios to developing tuberculosis were found in migrant citizens PLWHA who were males, non-Israeli born, those who were diagnosed with HIV/AIDS after 1997, those who originated in high-tuberculosis prevalence country and those who acquired HIV by heterosexual or drug-injection transmission. PLWHA who developed tuberculosis had higher odds of dying than other PLWHA (36.5% and 16.6%, respectively, p<0.001, odds ratio = 2.8, 95% confidence-interval 2.3-3.6). In survival-analysis, time to develop tuberculosis was shorter among males than females, in PLWHA who were reported with HIV after 1997, in heterosexual who originated in high-tuberculosis countries, followed by injecting drug-users, heterosexual from low-tuberculosis burden countries and men who have sex with men. CONCLUSION: Tuberculosis-incidence is higher among non-Israeli born PLWHA, with decreasing trends from 1991. Despite the moderate TB-rate disease among PLWHA, it remains an important cause for severe morbidity and mortality. Tuberculosis in PLWHA reflects mainly the tuberculosis-burden in the originating country and possibly also the mode of HIV-transmission.

Pulmonary resection for multidrug-resistant tuberculosis: the Israeli experience (1998-2011).

BACKGROUND: Multidrug-resistant tuberculosis (MDR-1B) presents a difficult therapeutic problem due to the failure of medical treatment. Pulmonary resection is an important adjunctive therapy for selected patients with MDR-TB. OBJECTIVES: To assess the efficacy of pulmonary resection in the management of MDR-TB patients. METHODS: We retrospectively reviewed the charts of MDR-TB patients referred for major pulmonary resections as part of a treatment strategy. The operations were performed in the departments of thoracic surgery at Assaf Harofeh and Wolfson Medical Centers. For the period under study, 13 years (1998-2011), we analyzed patients' medical history, bacteriological, medical and surgical data, morbidity, mortality, and short-term and long-term outcome. RESULTS: We identified 19 pulmonary resections (8 pneumonectomies, 4 lobectomies, 1 segmentectomy, 6 wedge resections) from among 17 patients, mostly men, with a mean age of 32.9 years (range 18-61 years). Postoperative complications developed in six patients (35.3%) (broncho-pleural fistula in one, empyema in two, prolonged air leakin two, and acute renal failure in one). Only one patient (5.84%) died during the early postoperative period, three (17.6%) inthe late postoperative period, and one within 2 years after the resection. Of 12 survivors, 9 were cured, 2 are still under medical treatment, and 1 is lost from follow-up because of poor compliance. CONCLUSIONS: Pulmonary resection for MDR-TB patients is an effective adjunctive treatment with acceptable morbidity and mortality.
