Infectious Diseases of the Circulatory System

  1. 1. Circulatory System – consist of Cardiovascular and Lymphatic System.
  2. 2. • Endocarditis – Inflammation of endocardium. • Myocarditis- Inflammation of myocardium. • Pericarditis- Inflammation of pericardium • Lymphadenitis – Inflammation of lymph nodes • Lymphadenopathy- Diseased lymph nodes. • Lymphangitis - Inflammation of lymph vessels
  3. 3. • “Human Immunodeficiency Virus” • A unique type of virus (a retrovirus) • Invades the helper T cells (CD4 cells) in the body of the host (defense mechanism of a person) • Threatening a global epidemic. • Preventable, managable but not curable.
  4. 4. • Former names of the virus include: •Human T cell lymphotrophic virus (HTLV-III) •Lymphadenopathy associated virus (LAV) •AIDS associated retrovirus (ARV)
  5. 5. • “Acquired Immunodeficiency Syndrome” • HIV is the virus that causes AIDS • Disease limits the body’s ability to fight infection due to markedly reduced helper T cells. • Patients have a very weak immune system (defense mechanism) • Patients predisposed to multiple opportunistic infections leading to death.
  6. 6. • Opportunistic infections and malignancies that rarely occur in the absence of severe immunodeficiency (eg, Pneumocystis pneumonia, central nervous system lymphoma). • Persons with positive HIV serology who have ever had a CD4 lymphocyte count below 200 cells/mcL or a CD4 lymphocyte percentage below 14% are considered to have AIDS.
  7. 7. • Icosahedral (20 sided), enveloped virus of the lentivirus subfamily of retroviruses. • Retroviruses transcribe RNA to DNA. Two viral strands of RNA found in core surrounded by protein outer coat. Outer envelope contains a lipid matrix within which specific viral glycoproteins are imbedded. These knob-like structures responsible for binding to target cell.
  8. 8. • Blood products • Semen • Vaginal fluids
  9. 9. • Sharing Needles •Without sterilization Increases the chances of contracting HIV • Unsterilized blades
  10. 10. •Unprotected Intercourse •Oral •Anal
  11. 11. • Before Birth • During Birth
  12. 12. • Short, flu-like illness - occurs one to six weeks after infection • Mild symptoms • Infected person can infect other people
  13. 13. • Lasts for an average of ten years • This stage is free from symptoms • There may be swollen glands • The level of HIV in the blood drops to low levels • HIV antibodies are detectable in the blood
  14. 14. • The immune system deteriorates • Opportunistic infections and cancers start to appear.
  15. 15. • The immune system weakens too much as CD4 cells decrease in number.
  16. 16. • Nucleoside Reverse Transcriptase inhibitors •AZT (Zidovudine) • Non-Nucleoside Transcriptase inhibitors •Viramune (Nevirapine) • Protease inhibitors •Norvir (Ritonavir)
  17. 17. • Abstinence • Monogamous Relationship • Protected Sex • Sterile needles • New shaving/cutting blades
