Syphilis
Causes of Syphilis
- Treponema pallidum bacterium
- Transmission through sexual contact (vaginal, anal, or oral sex) with someone who is infected
- Pregnant women can pass the infection to their babies (congenital syphilis)
- Direct contact with syphilis sores, rashes, or mucous membrane lesions
- Unprotected sex with multiple partners
- Sharing contaminated drug paraphernalia
Diagnosis
Medical History and Physical Examination:
A healthcare provider will review the patient’s medical history, including the presence of any symptoms or potential exposure to syphilis. They will also conduct a physical examination to check for any signs of the disease, such as rash, sores, or swollen lymph nodes.
Laboratory Tests:
Diagnosing syphilis requires specific laboratory tests, which may include:
- 1. Blood Tests (Serology): Blood samples are taken to detect antibodies produced by the body in response to a syphilis infection. Common blood tests include:
- – Venereal Disease Research Laboratory (VDRL) test
- – Rapid Plasma Reagin (RPR) test
- – Treponemal-specific tests (e.g., Fluorescent Treponemal Antibody Absorption test, Enzyme Immunoassay, etc.)
- 2. Polymerase Chain Reaction (PCR): PCR tests are used to detect the genetic material (DNA) of the syphilis bacteria in various body fluids or tissues.
- 3. Darkfield Microscopy: This test involves examining fluid from syphilis sores or other lesions under a special microscope to directly visualize the Treponema pallidum bacteria.
Imaging Studies:
In some cases, imaging studies may be necessary to assess the extent of syphilis infection. This may include:
- 1. X-rays: Chest x-rays can be used to check for syphilis-related complications, such as aortic damage in advanced stages of the disease.
- 2. Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scans: These imaging techniques help evaluate neurosyphilis (syphilis affecting the nervous system) or other organ involvement.
