The Challenges of Tuberculosis Management beyond Professional Competence: Insights from Tuberculosis Outbreaks among Ethiopian Immigrants in Israel.

Controlling tuberculosis (TB) among immigrants from high-incidence countries presents a public health concern as well as a medical challenge. In this article, we investigate a TB outbreak in a community of people of Jewish descent who emigrated from Ethiopia to Israel (Israeli Ethiopians) that started in June 2022. The index case was a 20-year-old female who had recently immigrated to Israel with her family. Her pre-immigration tuberculin skin test was positive. After excluding active TB, treatment with daily isoniazid for latent TB (LTB) was started shortly after her arrival. A year later, she was diagnosed with smear-positive, culture-positive, pulmonary TB. Investigation of 83 contacts revealed five additional patients with active TB, and three of whom were members were of her household. In this article, we report the current TB outbreak, review previously published TB outbreaks involving Israeli Ethiopians, analyze the factors that triggered each of these outbreaks, and discuss the challenges that face the Israeli TB control program in an era of declining TB incidence and diminishing resources available for TB control.

Latent Tuberculosis Treatment among Hard-to-Reach Ethiopian Immigrants: Nurse-Managed Directly Observed versus Self-Administered Isoniazid Therapy.

BACKGROUND: The treatment of latent tuberculosis infection (LTBI) among high-risk populations is an essential component of Tuberculosis (TB) elimination. However, non-compliance with LTBI treatment remains a major obstacle hindering TB elimination efforts. We have previously reported high treatment compliance with nurse-managed, twice-weekly, directly observed Isoniazid treatment (DOT) for LTBI among hard-to-reach Ethiopian immigrants (EI's). OBJECTIVES: to compare rate of completion of treatment, cost, and major adverse drug events with daily self-administered Isoniazid treatment (SAT) to nurse-managed Isoniazid DOT among hard-to-reach EIs. MATERIALS AND METHODS: We conducted a retrospective study and compared self-administered LTBI treatment outcomes among EIs housed in reception centers during 2008-2012 to EIs treated with DOT. RESULTS: Overall, 455 EIs were included (231 DOT, 224 SAT) in the study. We found no significant difference in treatment completion rates between the two groups (93.0% DOT vs. 87.9% SAT, p = 0.08). However, cases of grade III, drug-induced hepatitis were significantly fewer and treatment costs were significantly lower with the nurse-managed DOT compared with SAT (0% vs. 2.2%, p = 0.028, 363 vs. 521 United States Dollars, p < 0.001, respectively). CONCLUSIONS: Nurse-managed, twice-weekly DOT among hard-to-reach EIs housed in reception centers had less severe drug-related adverse events and reduced treatment cost compared with daily isoniazid SAT, yet we found no significant difference in treatment completion between the two strategies in this population.

An 80-year-old man with a right upper lobe opacity.

BACKGROUND AND AIMS: The differential diagnosis of a right upper lobe pulmonary opacity in an elderly afebrile patient includes infectious and malignant etiology. However, unilateral lung edema should also be included in the differential diagnosis. METHODS: Case report of an 80-year-old afebrile patient who presented with cough, dyspnea and blood-tinged sputum and had an isolated right upper lobe infiltrate on chest X-ray on whom a diagnostic work-up including computed tomography scan of the chest and echocardiography was performed. RESULTS: Bilateral alveolar opacities and pleural effusions, not apparent on the chest X-ray, and a flail posterior leaflet with severe mitral valve regurgitation were revealed. His symptoms and findings responded to diuretic treatment. CONCLUSION: Pulmonary edema should be considered in a patient with mitral valve regurgitation presenting with a unilateral lung infiltrate. Chest computed tomography scan findings consistent with heart failure and echocardiography demonstrating mitral valve regurgitation are the main clues to the diagnosis. Diuretic therapy should cause a rapid improvement of the radiologic and clinical findings.

Tuberculosis during Pregnancy in Northern Israel, 2002-2012: Epidemiology and Clinical Practices.

BACKGROUND: Atypical presentation of tuberculosis (TB) during pregnancy may cause diagnostic delay and adversely influence pregnancy outcome. OBJECTIVES: To examine the incidence and clinical and epidemiological features of TB during pregnancy and investigate infection control measures at delivery and during the postpartum period. METHODS: We retrospectively evaluated all reported cases of TB diagnosed during pregnancy to 6 months postpartum in Israel's Northern Health District (2002-2012). RESULTS: Active TB was detected in six patients; all were negative for human immunodeficiency virus (HIV). Two patients were diagnosed in the postpartum period, and four had pulmonary involvement. The average incidence during this period (3.9 per 100,000 pregnancies) was similar to that in the general population. Five patients were at high risk of contracting TB due to either recent immigration from a high-burden country or being in contact with another individual with active TB. Patients with pleuropulmonary involvement had prolonged cough and abnormal chest X-rays, without fever. Diagnosis was delayed for 3 to 7 months from symptom onset. Investigation of the newborn to rule out intrauterine infection was conducted in only one of four relevant cases. All patients were infected with organisms susceptible to all first-line drugs, and all were cured with standard therapy. CONCLUSIONS: There was a considerable delay in the diagnosis of TB among pregnant women, and investigation of the newborn upon delivery to rule out TB infection was routinely omitted. Effective management of TB during pregnancy and the postpartum period requires a multidisciplinary approach including an obstetrician, pediatrician, TB specialist, and public health physician.

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.

[Compliance with latent tuberculosis treatment: a public health challenge].

Tuberculosis (TB) is a major infectious cause of morbidity and mortality, mainly in developing countries. Since the incidence of TB has decreased in the developed countries, the role of diagnosis and treatment of latent TB infection (LTBI), has assumed increasing importance as a public health measure to control TB. It is estimated that 5-10% of persons with LTBI go on to develop TB; therefore, the crucial role of LTBI treatment in eliminating TB is well recognized. However, levels of adherence to treatment of LTBI are consistently low, and non-compliance constitutes the major barrier for achieving the full benefits of LTBI treatment, emphasizing the pressing need to implement compliance-enhancing interventions. We present a review of studies in which various interventions aimed at enhancing LTBI treatment adherence were applied.

[Accessibility and compliance of Ethiopian immigrants to latent tuberculosis infection treatment].

BACKGROUND: Since the incidence of TB has decreased in the developed countries, the diagnosis and treatment of latent TB infection (LTBI) has assumed increasing importance. It is estimated that 5-10% of persons with LTBI go on to develop TB; therefore, the crucial role of LTBI treatment in eliminating TB is well recognized. However, levels of adherence are found to be consistently low, and noncompliance constitutes the major barrier for achieving the full benefits of LTBI treatment. OBJECTIVE: 1. To estimate rates of treatment completion with an outreach - directly observed preventive treatment (DOPT), a program among Ethiopian immigrants (El) at absorption centers treated for LTBI. 2. To determine if follow-up visits by a physician at their place of residence, vs. management at a TB Clinic (TBC), would further enhance the patient's adherence. METHODOLOGY: Quasi experiment, retrospective cohort analysis of 495 medical records for all El at absorption centers in Zefat who had started DOPT for LTBI and were followed up at absorption centers (2005-2006, study group - SG), compared to patients followed up at a TBC (2008-2010, comparison group - CG). Free transportation to the TBC was provided for the CG. FINDINGS: Altogether 495 Els were included (263 in the SG and 232 in the CG group). Both groups had high completion rates (SG: 96.2% vs. CG: 93.1%, p=0.14). While demographic factors did not predict treatment completion, side effects were significantly associated with non-completion. CONCLUSION: High treatment completion rates among El were achieved when DOPT outreach and cultural case management strategies were combined. In these circumstances, the physician follow-up location had no significant impact on treatment completion rates.

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 in pregnancy and puerperium].

According to the World HeaLth Organization, tuberculosis (TB) is the third leading cause of death worldwide among women at child bearing age. However, in Israel, a low TB prevalence country, TB in pregnant women is infrequent and infectious pulmonary TB at puerperium is rare. Early diagnosis of TB in pregnancy is challenging because the non-specific symptoms of early TB such as weakness, excess perspiration and tachycardia will usually be attributed to pregnancy. Furthermore, since health care givers attempt to avoid superfluous exposure of the fetus to radiation, and pregnant women are reluctant to be X-rayed, the diagnosis of active TB may be further delayed, especially if the woman is not in a risk group for TB. However, delaying treatment of TB in a pregnant woman, especially in advanced pregnancy may lead to TB in the fetus, TB infection of the new born transmitted from the mother who may also infect other mothers and their infants in the maternity ward. We report a case of highly infectious active TB diagnosed in a pregnant woman one week before delivery. The woman, a native Israeli, had no risk factor for TB except her recent stay in a high burden TB country. We present the diagnostic workup and therapeutic approach to the pregnant patient, the newborn infant and the measures applied to control infection. Awareness of risk factors for TB, the elusive symptoms of the disease during pregnancy, and implementing the necessary diagnostic workup at delivery is vital to minimize pregnancy related TB morbidity.
