新生儿Netherton综合征1例

A case of neonatal Netherton syndrome

患儿,男,6 d,因生后呼吸困难伴全身脱屑样皮疹入院。患儿主要表现为生后红斑伴脱屑样皮疹、呼吸衰竭、反复感染、慢性腹泻、高渗性脱水、生长发育迟缓,予抗感染、静脉注射免疫球蛋白、皮肤护理等综合治疗后皮疹好转,但仍存在反复感染。二代测序检测示患儿存在SPINK5基因纯合变异,系Netherton综合征的致病变异。家属放弃治疗,患儿出院后于2月龄时死亡。该文报道1例新生儿期起病的SPINK5基因变异所致的Netherton综合征病例,以及对该疾病的多学科诊疗。

A male infant,aged 6 days,was admitted to the hospital due to respiratory distress and systemic desquamative rash after birth.The infant presented with erythema and desquamative rash,respiratory failure,recurrent infections,chronic diarrhea,hypernatremic dehydration,and growth retardation.Comprehensive treatment,including anti-infection therapy,intravenous immunoglobulin administration,and skin care,resulted in improvement of the rash,but recurrent infections persisted.Second-generation sequencing revealed a homozygous mutation in the SPINK5 gene,consistent with the pathogenic variation of Netherton syndrome.The family opted for palliative care,and the infant died at the age of 2 months after discharge.This report documents a case of Netherton syndrome caused by the SPINK5 gene mutation in the neonatal period,and highlights multidisciplinary diagnosis and therapy for this condition.
