ABSTRACT

Introduction: Acquired autoimmune myasthenia gravis (MG) is an autoimmune process in which antibodies (AB) directed against the acetylcholine nicotinic receptor (AChR) cause weakness and fatigue of striated muscles. Objectives: The objective of this study was to determine the range of clinical manifestations in newborns with transient neonatal myasthenia (TNM). Methods: 62 newborns with mothers who had autoimmune MG were followed by: anthropometric parameters, gestational age, gender, type of delivery completion, Apgar score (AS) in the first and fifth minute, and the emergence of TNM symptoms. Results: For fourteen consecutive years, from a total of 98,000 infants, 62 (0.06%) were born to mothers with autoimmune MG. Four of them (6.4%) had symptoms of TNM. Conclusion: Newborns of mothers with MG manifest clinical features of TNM relative to stage of mother's illness. These newborns need monitoring until the seventh day of life.
