24 Tuberculosis in the Traveler Waterloo Regional TB clinic July 8, 2014 Second case in a traveler?increasing issue with increased travel abroad Delayed diagnosis as not in typical risk group What are recommendations for screening travelers?

25 * * Opportunities in our cases

26 Identification of Patients with Respiratory TB Disease within Hospitals

27 Diagnose active Tuberculosis the curve ball Suspicion in high risk groups Cough for three weeks initially non-productive Fever and night sweats common Hemoptysis, anorexia, weight loss, chest pain in more advanced disease CXR: apical posterior upper lobes, superior segment lower lobes; volume loss ;cavitation, pleural effusion Sputum x 3?induced bronchoscopy

28 Diagnosis & Treatment of Latent Tuberculosis (LTBI) The selection of people for targeted LTBI screening and treatment is based on: 1. their risk of prior TB exposure 2. their risk of reactivation 3. balanced against the likelihood of safe completion of treatment, including the risk of hepatotoxicity, which increases with age. TST Tuberculin skin test (TST) or interferon gamma release assay (IGRA)

29 TST All TST <65 yrs Homeless, IDU, immigrants & refugees Only <50 yrs

34 Travelers to Canada

35 Which Countries are High risk?

36 Travelers to Canada with Active TB Most foreign-born groups undergo a mandatory medical examination prior to arrival in Canada, which includes chest radiography to detect active TB. Those found to have active TB must be treated prior to arrival to ensure that they are no longer infectious (.05-2%) Citizenship and Immigration Canada (CIC) requires that individuals with previously treated TB and those with abnormal chest radiographs but without active TB detected in this program undergo TB surveillance after arrival. (1.3%) Only a small proportion (2-15%) of all cases of active TB diagnosed in the foreignborn after arrival in Canada are detected during the immigration post-landing surveillance program. This underscores the need for additional screening programs for subgroups of the foreign-born at increased risk of TB reactivation. Risks beyond the first 5 years! (only 44% within 5 years)

37

38 Challenges to LTBI screening & treatment of immigrants 1. Large number 2. Immigrants return home for prolonged periods without travel advice 3. Patient barriers: stigma, linguistic, economics, risk perception/bcg 4. Provider barriers: knowledge 5. Focus on higher risk

41 Immigrants returning Home 20% cases in U.K. were in immigrants returning to India 56% TB cases in Moroccans in Netherlands associated with recent travel to Morocco

42 Health Care Worker

43 Health Care Worker

44 What about our cases? M.D. 30 year old South Korea x 3 years & Mongolia x 10months??TST 2 months after return and education before Diagnosis delayed due to patients factor (eg. Smoking and no family MD)

45 Travel: South Korea , (90/100,000) Africa (?countries) 2009 x 2 months India 2010 x?2 months (168/100,000) Vietnam x?(200/100,000) What about our cases? Cambodia x? (442/100,000) R.N. 32?TST 2 months after return; education before Delayed diagnosis also due to initial Normal CXRs; pneumonia response to prolonged levofloxacin; lower lobe disease but significant travel history missed!

46 Problem with Treatment of LTBI

47 Problem with Treatment of LTBI only 26% complete! 1. Only 69% screened 2. Exclude active disease 3. Only 77% offered 4. Refused ( 83% accepted----target 80%) 5. Not completed (71%completed---target 80%) 6. toxicity

48 Tubersol Free Publically funded Tubersol is still available from Public Health for testing : 1. Contacts of active cases of TB and healthcare workers at high risk of TB exposure 2. Medically indicated individuals that are at increased risk of developing active TB (diabetes, HIV, renal failure, immunosuppressant medications) or to evaluate symptoms suggestive of TB 3. Individuals requiring admission to treatment rehabilitation centres 4. Resident admissions to Long-Term Care facilities 5. Recent arrivals Immigrants / Refugees within five years of arrival Tubersol is not available to GP s for 3 rd party testing such as educational institution, employment or volunteering Referral form and other links are available of the Public Health Website Public Health Main # ask for TB program
