Epidemiology zLeading infectious cause of death world wide. zIncreasing in the far east and Africa especially in association with AIDS. zIncreasing in London and the UK z40x more likely to have in lifetime if of Asian origin.
Pathology zInfection with Mycobacterium tuberculosis. Mainly in upper of lobe of lungs. zInitial infection in childhood, primary infection. This heals and becomes calcified. zReactivation when host becomes immunosuppressed.
Manifestations zMiliary TB acute diffuse dissemination of tubercle bacilli via the blood stream. zPresents very non specifically, weight loss ill health fever. zMantoux test is normally +ve though can be -ve in severe disease.
Adult post primary pulmonary TB zGeneral onset of non specific symptoms. zMain features fever, cough, weight loss. zSputum mucoid, purulent or blood stained. zPleural effusion or pneumonia. zFinger clubbing is present with advanced disease.
Investigations zChest X-Ray patchy nodular shadows in upper zone. zStaining Ziehl-Nielson culture takes 4-8 weeks. zBronchoscopy if no sputum. zBiopsy of lymph nodes. zDirect testing for rapid result using PCR.
Management zSensitive organisms use. zRifampicin, S/E inducer of liver enzymes, should be stopped if bilirubin is elevated. zIsoniazid, can cause a polyneuropathy at high doses. Can cause nausea and vomiting. zPyrazinamide reduces renal excretion of urate and an precipitate hyperuraemic gout. Can cause hepatotoxicity. zIf resistant use ethambutol or myambutol. These can cause optic retro bulbar neuritis. All patients must be seen by an ophthalmologist prior to treatment.
Control and prevention zTB is a notifiable disease. zAll close contacts are screened with a mantoux test and a chest X-Ray. zPrevention is with immunisation with BCG vaccination administered at 12-13 in the UK zAdministered at birth to groups at high risk
