Neonatal lupus erythematosus: our local experience

Area of Science:

• Dermatology
• Immunology
• Pediatrics

Background:

• Neonatal lupus erythematosus (NLE) is an autoimmune condition affecting newborns.
• It is associated with the transplacental transfer of maternal anti-Ro antibodies.
• Clinical manifestations include cutaneous lesions and cardiac abnormalities.

Purpose of the Study:

• To report on a series of 10 cases of neonatal lupus erythematosus.
• To describe the clinical presentation, maternal history, and outcomes of NLE.
• To highlight the occurrence of NLE in siblings.

Main Methods:

• Retrospective case series analysis of 10 NLE patients.
• Data collected from the National Skin Centre between 1990 and 1998.
• Review of clinical presentation, maternal autoimmune disease history, and infant outcomes.

Main Results:

• The female to male ratio was 2.3:1.
• Most infants presented with rash between 3-5 weeks of life; 4 had lesions at birth.
• The rash resolved spontaneously between 3 to 6 months of age.

Conclusions:

• Neonatal lupus erythematosus presents with characteristic skin lesions that typically resolve spontaneously.
• Maternal autoimmune conditions, such as SLE and Sjogren's syndrome, are frequently observed.
• Early identification and monitoring are crucial for managing NLE.
