Phage Therapy in a 16-Year-Old Boy with Netherton Syndrome.

ABSTRACT: Netherton syndrome (NS) is a rare autosomal recessive disorder, characterized by a classical triad of clinical features, including congenital ichthyosiform erythroderma, trichorrhexis invaginata, and atopic diathesis coupled with frequent bacterial infections (1). The genetic basis for the disease has been recently identified with mutations in gene SPINK5, which is involved in the regulation of formation of skin barriers. We report on a 16-year-old male with all the typical manifestations of NS, including atopic diathesis and ongoing serious staphylococcal infections and allergy to multiple antibiotics whose family sought help at the Eliava Phage Therapy Center when all other treatment options were failing. Treatment with several antistaphylococcal bacteriophage preparations led to significant improvement within 7?days and very substantial changes in his symptoms and quality of life after treatment for 6?months, including return visits to the Eliava Phage Therapy Center after 3 and 6?months of ongoing use of phage at home.

Project description:ImportanceNetherton syndrome (NS) is a rare, severe genetic disorder of cornification with high morbidity. Treatment for NS has been notoriously difficult. Recent studies showed an upregulated helper T cell (TH) 17/interleukin 23 (IL-23) pathway in NS, suggesting the possibility of treatment strategies that target IL-17.ObjectiveTo evaluate the clinical response of NS to treatment with the IL-17 antagonist secukinumab.Design, setting, and participantsThis case series study reports the experience of compassionate use therapy with secukinumab in 4 patients with severe NS, including 2 children, from December 1, 2018, to December 1, 2019, with 3 patients still undergoing treatment at the time of final analysis. Data were analyzed from December 1, 2018, to December 1, 2019.Main outcomes and measuresExpression of IL-17 in the skin was evaluated by immunohistochemical analysis, and serum cytokine concentrations were measured using a commercially available assay. Treatment response was assessed using the Ichthyosis Area and Severity Index (IASI) total score, including measures of erythema and scaling, the Dermatology Life Quality Index (DLQI), and the 5-D itch scale.ResultsIn all 4 patients (age range, 9-27 years; 3 male and 1 female), immunostaining with an IL-17A antibody showed an increased number of positive cells in lesional skin. Cytokine assessment in serum samples revealed increased levels of CCL20. Treatment duration with secukinumab was 3 to 12 months at the time of this report. After 3 months of therapy, IASI scores were reduced by 44% to 88%, DLQI scores were reduced by 40% to 76%, and 5-D itch scale scores were reduced by 27% to 62%. This outcome was sustained at the 6-month follow-up. Two patients with an erythrodermic phenotype showed marked improvement of all parameters. A refractory palmoplantar eczematous eruption occurred in 2 patients, and a candidal nail infection developed in 2 patients. No severe adverse events were reported.Conclusions and relevanceThis initial case series reporting the use of anti-IL-17 therapy in NS demonstrated marked cutaneous improvement, particularly in 2 pediatric patients with erythrodermic phenotypes. Further studies are needed to evaluate the long-term benefit of this potential treatment modality.
