Prevalence of Latent Tuberculosis Infection Among Rheumatology Patients and Management Practices in the United Arab Emirates: A Single-Center Retrospective Cohort Study

Introduction Prior to immunosuppression, rheumatology patients are routinely screened for latent tuberculosis (TB) infection using interferon-gamma release assays (IGRAs). Variability in the management of latent and indeterminate IGRA results across institutions limited long-term outcome data. A retrospective study was conducted at Tawam Hospital, United Arab Emirates, to investigate the incidence and management protocols associated with positive and indeterminate IGRA results, as well as TB infection, among patients with rheumatic conditions. Methods A single-center retrospective observational study was performed at Tawam Hospital, Abu Dhabi, UAE. Ethical approval for this study was obtained from the Tawam Human Research Ethics Committee. Laboratory records and the hospital's electronic medical system were used to obtain information about IGRA results over a 12-year period (April 2010-April 2022). The hospital's electronic medical system was used to obtain patient information and subsequent management approaches of positive and indeterminate IGRAs. Moreover, long-term follow-up data were collected to determine the risk of TB reactivation in the cohort. Results We found a total of 1,012 positive and 223 indeterminate IGRA test results within the 12-year period. Within the rheumatology department, 123 positive and 39 indeterminate IGRA results were identified. In the indeterminate IGRA group, the majority were women (n = 24, 61.5%) and UAE nationals (n = 22, 56.4%), and their mean age was 38.6 years. Systemic lupus erythematosus was the most prevalent rheumatologic condition (n = 21, 53.8%). Thirteen (33.3%) were on disease-modifying anti-rheumatic drugs (DMARDs) and 26 (66.7%) were on corticosteroids during IGRA testing. A total of eight patients (20.5%) received anti-TB medications. In the positive IGRA group, the mean age was 55.7 years and the female-to-male ratio was 3:1. The most common rheumatologic condition was rheumatoid arthritis (n = 69, 56%). Sixty-five (52.8%) patients were on conventional DMARDs, 43 (34.9%) were on corticosteroids during IGRA testing, and 74 (60%) received anti-TB medications. Two cases (1.6%) of active TB infections were detected among patients with positive IGRA tests, both of whom were receiving anti-tumor necrosis factor alpha inhibitor treatment in combination with methotrexate. No cases of active TB infection were observed in the indeterminate IGRA group. Conclusion Long-term data on the risk of TB activation in positive and indeterminate IGRA results for rheumatological conditions are low. It is recommended to reassess the choice of using anti-TNF-α, with a positive IGRA result if no other feasible alternatives can be offered. Our findings stress the importance of age, underlying diseases, and immunosuppressive treatments in interpreting IGRA results and guiding patient management. A large multicenter study is needed to understand the differences and outcomes of such patients in TB endemic and nonendemic geographical areas.

Mental health, wellbeing and burnout among medical students in the United Arab Emirates

BACKGROUND

Medical students tend to experience high levels of stress during their studies, that can result in mental health disorders and burnout, further affecting academic performance and later ability to practice.

AIMS

To investigate previous and current mental health issues, significant sources of stress, burnout, and substance use among medical students in the United Arab Emirates (UAE).

METHOD

We conducted an online survey to collect data on demographics, sources of stress, mental health problems, burnout, and substance use in 385 medical students from the UAE University. We used the Oldenburg Burnout Inventory (OLBI), the General Health Questionnaire 12 (GHQ-12), and the CAGE questionnaire.

RESULTS

Our results indicated that 5.7% of participants had been diagnosed with a mental health condition prior to joining medical school, and that 21.6% of participants were diagnosed with a mental illness while in medical school. On the OLBI, 77.4% screened positive for burnout (81.3% for disengagement and 95.1% for exhaustion), with 74.5% screening positive for mental health difficulties on the GHQ-12 and <1% screening positive on the CAGE for problem drinking. There was a statistically significant positive correlation between scores on the OLBI and the GHQ-12.

CONCLUSIONS

Our study indicated that high levels of stress, burnout and mental illness are experienced among medical students in the UAE.
