Presentation Transcript

  1. Smoking and Infectious Disease Tuberculosis and Legionnaires' Disease

  2. Tuberculosis  • Mycobacterium Tuberculosis  • Aerosol transmission • Latent vs. active tuberculosis

  3. The association between smoking and tuberculosis has been investigated since 1918 

  4. Tuberculosis Diagnosis  • Latent TB granulomas can be seen on a chest xray •  Mantoux skin test http://www.health.state.mn.us/divs/idepc/diseases/tb/tst.html http://www.cmaj.ca/content/169/9/937.full

  5. Tuberculosis Treatment • Suggested treatment according to the CDC includes: • ACTIVE--  • isoniazid (INH) • rifampin (RIF) • ethambutol (EMB) • pyrazinamide (PZA) • LATENT-- • isoniazid (INH)

  6. Tuberculosis Prevalence • Tuberculosis (TB) is one of the most important infectious diseases in the world in terms of morbidity and mortality • In 2008, the number of deaths due to TB was estimated at 1.8 million by the World Health Organization (WHO)  • In 2008, an estimated 0.48 million new cases occurred in South Africa and, currently, the country ranks third after India and China in terms of total number of annual incident cases of TB

  7. Active Tuberculosis Studies Reviewed

  8. The reduction of tuberculosis risks by smoking cessationWen, et al.--2010

  9. Tobacco smoking and pulmonary tuberculosisKolappan, Gopi--2002

  10. Latent Tuberculosis Studies Reviewed

  11. High prevalence of smoking among patients with suspected tuberculosis in South AfricaBurnet, et al.--2011

  12. The impact of smoking on adherence to treatment for latent tuberculosis infectionLavigne, et al.--2005

  13. Relapse of Tuberculosis Studies Reviewed

  14. Smoking increases the risk of relapse after successful tuberculosis treatmentBatista, et al.--2008

  15. Comparison of pulmonary and extrapulmonary tuberculosis in Nepal- a hospital-based retrospective studySreeramareddy, et al.--2008 • Smokers less likely to have isolated extrapulmonary TB • History of TB associated with pulmonary TB • No identification if this was a relapse or reinfection • Reinfection more common in high burden countries

  16. Mortality from Tuberculosis Studies Reviewed

  17. Smoking and risk of tuberculosis incidence, mortality, and recurrence in South Korean men and womenJee, et al.--2009

  18. Smoking and mortality from tuberculosis and other diseases in India: retrospective study of 43 000 adult male deaths and 35 000 controlsGajalakshmi, et al.--2009

  19. Barcelona Tuberculosis Data Reviewed/ Analyzed

  20. Tuberculosis and recurrence and its associated risk factors among successfully treated patientsMillet, et al.--2009

  21. Analysis of recent data collected by the Barcelona Public Health Agency • Data collected on 5,141 males and females living in Barcelona • SPSS used to calculate frequencies and percentages for the following associations: • OUTCOME and: • sex, country of origin, diabetes status, alcohol, homelessness, DOT therapy, imprisonment status, HIV status, and smoking status • SMOKING STATUS and: • sex, country of origin, diabetes status, alcohol, homelessness, DOT therapy, imprisonment status, and HIV status

  22. Legionnaires’ Disease • Legionella pneumophila • Low reporting rate • Can be lethal • Aerosol transmission • Risk factors: • Old age • Smoking • Chronic lung disease • Immunosuppression

  23. Legionnaires’ Diagnosis and Treatment • Diagnosis • Chest x-ray • Sputum culture • Urinary antigen test • Blood antibody test • Treatment • Antibiotics http://www.wrongdiagnosis.com/phil/html/legionnaires-disease/192.html

  24. Legionnaires’ Disease Data Reviewed/ Analyzed

  25. Sporadic community-acquired Legionnaires’ disease in France: a 2-year national matched case-control studyChe, et al.--2008

  26. Analysis of recent data collected by the Barcelona Public Health Agency • Data collected on 1,018 males and females living in Barcelona • SPSS used to calculate frequencies and percentages for the following associations: • OUTCOME and: • sex, country of origin, diabetes status, alcohol, cardiopulmonary disease, immunosuppressive treatment and disease, renal transplant, cancer status, and smoking status • SMOKING STATUS and: • sex, country of origin, diabetes status, alcohol, cardiopulmonary disease, immunosuppressive treatment and disease, renal transplant, cancer status
