A case of neonatal Netherton syndrome / 中国当代儿科杂志

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.

A severe case of netherton syndrome in a Filipino child

Objective@#To present a rare case of Netherton Syndrome (NS) in a Filipino child. @*Case@#This is a case of an 11-year-old girl with elevated immunoglobulin E, trichorrhexis nodosa, and ichthyosis linearis circumflexa. She had dry skin with fine scaling at birth with recurrent pruritic, erythematous papules coalescing to plaques mainly on the face and extensors. The skin dryness turned to generalized redness with fine scaling, and the skin started getting tight. She could no longer completely extend both knees, but she was still able to walk. She also started having difficulty closing both eyes. She developed migratory serpiginous erythematous plaques with peripheral double-edged scaling. At six years old, she developed ulcers in the scalp, trunk, and extremities, which resulted in admission to our institution. She was managed for multiple skin infections, pneumonia, sepsis, seizure, severe malnutrition, joint contracture, atopy, and bilateral cicatricial ectropion.@*Conclusion@#Management of NS remains challenging. Common management options include emollients, topical corticosteroids, calcineurin, and protease inhibitor, and phototherapy while newer ones that need further validation include intravenous immunoglobulins and biologics such as infliximab. However, until specific recommendations are made, overall management for NS remains challenging. Regular multidisciplinary monitoring of the manifestations of NS is central to its management.

Netherton syndrome in a 1-year-old Filipino female

@#Netherton syndrome (NS) is an autosomal recessive genodermatosis characterized by cutaneous and systemic complications (recurrent infections, dehydration, and sepsis). This highlights the urgency of making an accurate diagnosis, especially in infants and children. However, it is important to note that the recognition of NS is usually delayed due to its rarity and similarity to cutaneous disorders with atopiform, erythrodermic, and ichthyosiform presentations. We report a case of a 1-year-old female who was previously diagnosed with a case of infantile psoriasis and was subsequently treated with topical emollients. However, after months of surveillance, the patient developed feeding problems, failure to thrive, recurrent diarrhea, upper respiratory tract, and gastrointestinal infection, leading to repeated hospitalizations. The patient then underwent further clinical examinations and laboratory analysis, which revealed abnormal hair shaft findings, elevated immunoglobulin (Ig) E levels, and normal chromosomal analysis. Multispecialty referrals with other services were done to address the current problems and ensure holistic care for the patient. On her last admission, the patient was given three doses of intravenous Ig therapy with noted improvement in lesion presentation without any systemic symptoms.

Síndrome de Netherton: el caso de un recién nacido con insuficiencia respiratoria / Netherton syndrome: A neonatal case with respiratory insufficiency

El síndrome de Netherton (SN) es una enfermedad autosómica recesiva, muy poco frecuente, que se caracteriza por la presencia de eritrodermia ictiosiforme congènita, anomalías capilares y manifestaciones atópicas. Este síndrome es consecuencia de una mutación recesiva en el gen SPINK5. Las manifestaciones del síndrome de SN varían considerablemente entre las personas que lo padecen. Aquí informamos el caso de un recién nacido que presentaba insuficiencia respiratoria grave, hipotermia y eritrodermia, al que se le diagnosticó SN, confirmado mediante pruebas genéticas moleculares.

Netherton syndrome (NS) is a rare, autosomal recessive disease characterized with congenital ichthyosiform erythroderma, hair abnormality and atopic manifestations. This syndrome is caused by recessive mutation in the SPINK5 gene. Disease manifestations vary considerably among NS individuals. We report a newborn presented with severe respiratory insufficiency, hypothermia and erythroderma, was diagnosed as having NS and confirmed with molecular genetic testing.

Ictiosis sindrómicas / Syndromic ichthyosis

Las ictiosis hereditarias son un grupo de desórdenes mendelianos, con manifestaciones clínicas y alteraciones genéticas heterogéneas caracterizadas por la presencia de escamas y/o hiperqueratosis. Las ictiosis sindrómicas son aquellas en las que el defecto genético se manifiesta en la piel y también en otros órganos. Presentamos 7 pacientes con ictiosis sindrómicas: un síndrome IFAP (ictiosis folicular, atriquia, fotofobia), un síndrome de Conradi-Hünermann-Happle (CHH), dos síndromes de Netherton (SN), dos síndromes de Sjögren-Larsson (SSL) y un síndrome KID (queratitis, ictiosis, sordera). Se analizan las características clínicas y diagnósticas de nuestros pacientes (AU)

Inherited ichthyosis are a group of clinical and genetic heterogeneous disorders characterized by the presence of scales, hyperkeratosis or both. In syndromic ichthyosis, the genetic defect involves the skin and other organs. We present 7 patients with syndromic ichthyosis: a case of IFAP syndrome (ichthyosis follicularis with alopecia and photophobia), a case of Conradi-Hünermann-Happle (CHH) syndrome, two cases of Netherton syndrome, two cases of Sjögren-Larsson syndrome and a case of KID syndrome (keratitis, ichthyosis and deafness). We analyze the diagnostic and clinical features of our patients (AU)

Trichoscopy as a diagnostic tool in trichorrhexis invaginata and Netherton syndrome

Netherton syndrome is a rare autosomal recessive disease characterized by erythroderma, ichthyosis linearis circumflexa, atopy, failure to thrive and a specific hair shaft abnormality called trichorrhexis invaginata or bamboo hair, considered pathognomonic. We report the case of a 4-year-old boy with erythroderma since birth, growth deficit and chronic diarrhea. Trichoscopy was used to visualize typical bamboo and "golf tee" hair and of key importance to diagnose Netherton syndrome. We suggest the use of this procedure in all children diagnosed with erythroderma.

Netherton Syndrome in Two Sisters / 대한피부과학회지

Netherton Syndrome is a rare autosomal recessive inherited disorder, characterized by triad of congenital ichthyosiform dermatosis, trichorrhexis invaginata and atopy diathesis. It has been found to be due to mutations in SPINK5, a gene encoding LEKTI (lympho-epithelial Kazal-type related inhibitor). LEKTI is a serine proteinase inhibitor that is expressed in epithelial and lymphoid tissues, and may be important in the keratinocyte terminal differentiation and T and B cell maturation. We herein report two cases of Netherton Syndrome in sisters who had ichthyosis linearis circumflexa, trichorrhexis invaginata and atropic dermatitis.
