Syphilis complicating pregnancy, third trimester

Clinical Classification Guidelines

Medical Intelligence & Overview

Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. When this infection occurs during pregnancy, particularly in the third trimester, it can lead to serious complications for both the mother and the developing fetus. Proper management and treatment are essential to prevent adverse outcomes. The ICD-10 code O98.113 refers specifically to cases where syphilis complicates pregnancy in the third trimester, highlighting the importance of timely diagnosis and intervention.

Causes & Symptoms

Clinical Causes: Unprotected sexual contact with a partner infected with syphilis Transmission from untreated or inadequately treated syphilis infection Vertical transmission from mother to fetus during pregnancy Reinfection during pregnancy if exposed again

Key Symptoms: Signs of syphilis in the mother, which may include sores, rashes, or flu-like symptoms (though often asymptomatic) Possible developmental issues in the fetus, such as growth restriction Stillbirth or miscarriage Preterm birth Birth of a baby with congenital syphilis, showing signs like skin ulcers, nasal discharge, or skeletal abnormalities

Diagnostic & Treatment

Diagnosis Path: Serologic blood tests such as rapid plasma reagin (RPR) or Venereal Disease Research Laboratory (VDRL) test Confirmation with specific treponemal tests like the fluorescent treponemal antibody absorption (FTA-ABS) test Assessment of maternal symptoms and medical history Ultrasound examinations to monitor fetal development and identify any complications Testing the newborn for congenital syphilis if the mother was infected during pregnancy

Treatment Protocols: Administering intramuscular injections of penicillin, which is the preferred treatment for pregnant women with syphilis Monitoring the mother’s response to treatment through follow-up blood tests Conducting additional testing to ensure cure has been achieved Providing supportive care for the newborn if congenital syphilis is diagnosed, including antibiotics and supportive therapies
