(Ananda Wijewickrama.

The prevalence rose to 49% in those with a CD4 count below 100 CD4 cells/L. </p><p> [NEJM 1991; 324:1644 ,4] </p></li><li><p> Urine cultures GU TB rarely occurs. But, frequently involved in disseminated TB, even in the absence of pyuria. In one series, 61 of 79 (77%) HIV-infected patients with extrapulmonary TB had urine culture positive for MTB [Medicine 1991; 70:384.]. </p><p> Stool cultures are helpful to diagnose MAC infection, but are less useful for diagnosing TB. MTB in the stool is usually derived from swallowed mucus and represents pulmonary rather than enteric TB </p></li><li><p>Case history . </p><p>23 yr. old boy with Milliary TB. </p></li><li><p>TB EXTRAPULMONARY </p></li><li><p> Oesophageal Candidiasis </p><p>Organism: Candida yeast </p><p>CD4 count &lt; 200 </p><p>Clinical symptoms dysphagia, retrosternal pain </p><p> oral thrush in 50-90% </p><p> endoscopy ulceration, plaques </p><p>Diagnosis </p><p> oral thrush and dysphagia sufficient </p></li><li><p> Recurrent Pneumonia </p><p> Organism </p><p> S. pneumoniae H. influenzae </p><p> S. aureus enteric gram neg rods </p><p> M.TB </p><p> Rhodococcus equi </p><p> Nocardia asteroides </p><p> Stage of HIV Infection </p><p> early and late </p><p> late </p><p> early and late </p><p> late </p><p> late </p></li><li><p>Dengue in patients with HIV </p><p>Dengue in patients with HIV in Sri Lanka </p><p>(Ananda Wijewickrama et al. 9th ICAAP in Indonesia in August 20009) </p><p>10 confirmed Dengue cases in HIV.

They often present with opportunistic infections. Clinicians should have a high degree of suspicion. </p><p> As the ARV is started early and is given free of charge, many are on long term drugs. Presentations due to long term drug side effects are becoming commoner. Coordinated care is necessary. </p></li><li><p>THANK YOU ! </p></li></ul>
