[PMID: 38126177 DOI: 10.1111/ajd.14197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 11/13/2023] [Accepted: 11/21/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND/OBJECTIVES Recent literature highlights the potential of biologics in the management of inherited disorders of keratinisation. In this study, we conducted a systematic review of existing literature on treatment outcomes of inherited keratinisation disorders treated with biologics. METHODS Eligible records were retrieved through searches of the electronic databases MEDLINE, Embase, PubMed and Scopus. Databases were searched from inception to July 2023 for eligible records. A snowballing method was employed to search the references of the retrieved records for the identification of potentially relevant articles. RESULTS One hundred and four eligible studies consisting of a total of 166 patients with an inherited disorder of keratinisation were included. Patients had a median age of 19 years (range: 0.5 to 70 years). The most common disorders were Netherton syndrome (n = 63; 38%), autosomal recessive congenital ichthyoses (n = 27; 16%), CARD14-associated papulosquamous eruptions (n = 17; 10%) and familial pityriasis rubra pilaris (PRP) (n = 15; 9%).Of the 207 times biologics were employed, the three most frequently employed biologics were secukinumab (n = 47; 23%), dupilumab (n = 44; 21%) and ustekinumab (n = 37; 18%). Complete remission was observed in 10 (5%) instances, partial remission in 129 (62%), no or limited response to biologic therapy in 68 (32%) cases, and results are still pending in one case. A total of 33 adverse events were reported. CONCLUSIONS Whilst biologics may be considered in cases of inherited keratinisation disorders recalcitrant to standard therapy, definitive conclusions are prohibited by the low-level of evidence and substantial heterogeneity in methodology across the included studies. Establishment of consensus definitions, and randomised clinical trials may help ascertain the efficacy and safety of biologic therapy in this context and establish the best agent and dosing protocol for each disorder.

Abstract
The congenital photosensitivity disorders present as cutaneous signs and symptoms secondary to photosensitivity, extracutaneous manifestations, and a predisposition to malignancy. Diagnosis of these conditions mainly depend on clinical findings as the molecular analysis is not always feasible. A review of all the related articles collected after a thorough literature search using keywords, "congenital AND photosensitivity NOT acquired" and the individual diseases was done. A total of 264 articles were included in the review. An algorithm for diagnosis of the different congenital photosensitivity disorders based on the various clinical presentations has been proposed. An early suspicion and diagnosis of the different congenital photosensitivity disorders is the cornerstone behind prompt institution of prevention and treatment, and decreasing the associated morbidity.

Abstract
Dupilumab was first approved for the treatment of atopic dermatitis (AD) and blocks the signaling of interleukin (IL)-4 and -13. Several other chronic skin conditions share mechanistic overlaps with AD in their pathophysiology, i.e., are linked to type 2 inflammation. Most recently, dupilumab was approved by the U.S. Food and Drug Administration for prurigo nodularis (PN). Given its relatively good safety profile, effective off-label use of dupilumab has been reported for a multitude of dermatologic diseases and several clinical trials for dermatologic skin conditions are currently ongoing. We conducted a systematic review of applications of dupilumab in dermatology other than AD and PN by searching the databases PubMed/Medline, Scopus, Web of Science and Cochrane Library as well as the clinical trial registry ClinicalTrials.gov. We found several reports for effective treatment of bullous autoimmune diseases, eczema, prurigo, alopecia areata, chronic spontaneous urticaria, Netherton syndrome and a variety of other chronic inflammatory skin diseases.

[PMID: 36810639 DOI: 10.1038/s10038-023-01134-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2022] [Revised: 02/12/2023] [Accepted: 02/12/2023] [Indexed: 02/24/2023]
Abstract
Among genodermatoses, trichothiodystrophies (TTDs) are a rare genetically heterogeneous group of syndromic conditions, presenting with skin, hair, and nail abnormalities. An extra-cutaneous involvement (craniofacial district and neurodevelopment) can be also a part of the clinical picture. The presence of photosensitivity describes three forms of TTDs: MIM#601675 (TTD1), MIM#616390 (TTD2) and MIM#616395 (TTD3), that are caused by variants afflicting some components of the DNA Nucleotide Excision Repair (NER) complex and with more marked clinical consequences. In the present research, 24 frontal images of paediatric patients with photosensitive TTDs suitable for facial analysis through the next-generation phenotyping (NGP) technology were obtained from the medical literature. The pictures were compared to age and sex-matched to unaffected controls using 2 distinct deep-learning algorithms: DeepGestalt and GestaltMatcher (Face2Gene, FDNA Inc., USA). To give further support to the observed results, a careful clinical revision was undertaken for each facial feature in paediatric patients with TTD1 or TTD2 or TTD3. Interestingly, a distinctive facial phenotype emerged by the NGP analysis delineating a specific craniofacial dysmorphic spectrum. In addition, we tabulated every single detail within the observed cohort. The novelty of the present research includes the facial characterization in children with the photosensitive types of TTDs through the 2 different algorithms. This result can become additional criteria for early diagnosis, and for subsequent targeted molecular investigations as well as a possible tailored multidisciplinary personalized management.

Abstract
Repair of genomic DNA is a fundamental housekeeping process that quietly maintains the health of our genomes. The consequences of a genetic defect affecting a component of this delicate mechanism are quite harmful, characterized by a cascade of premature aging that injures a variety of organs, including the nervous system. One part of the nervous system that is impaired in certain DNA repair disorders is the peripheral nerve. Chronic motor, sensory, and sensorimotor polyneuropathies have all been observed in affected individuals, with specific physiologies associated with different categories of DNA repair disorders. Cockayne syndrome has classically been linked to demyelinating polyneuropathies, whereas xeroderma pigmentosum has long been associated with axonal polyneuropathies. Three additional recessive DNA repair disorders are associated with neuropathies, including trichothiodystrophy, Werner syndrome, and ataxia-telangiectasia. Although plausible biological explanations exist for why the peripheral nerves are specifically vulnerable to impairments of DNA repair, specific mechanisms such as oxidative stress remain largely unexplored in this context, and bear further study. It is also unclear why different DNA repair disorders manifest with different types of neuropathy, and why neuropathy is not universally present in those diseases. Longitudinal physiological monitoring of these neuropathies with serial electrodiagnostic studies may provide valuable noninvasive outcome data in the context of future natural history studies, and thus the responses of these neuropathies may become sentinel outcome measures for future clinical trials of treatments currently in development such as adeno-associated virus gene replacement therapies.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize and highlight the recent literature in photodermatoses. In the past year, there have been many developments in this heterogeneous group of conditions. RECENT FINDINGS This review is divided by photodermatoses type, which include idiopathic photodermatoses, photodermatoses secondary to exogenous agents, photodermatoses secondary to endogenous agents (the porphyrias), and genodermatoses. The idiopathic photodermatoses section focuses on case series and reports highlighting new disease presentations or further disease characterization and new treatment strategies for these disorders. The second section discusses a unique case and has a brief update on photoallergens. Clinical, diagnostic, and treatment updates for porphyrias are discussed in Section 3. For genodermatoses, we discuss complications and neoplastic risk of xeroderma pigmentosum and a few highlights from other rare disorders. Finally, we conclude with a brief overview of photoprotection updates, from assessing sun-damaged skin to the most effective photoprotective agents. SUMMARY Up-to-date information will help providers identify and manage this rare group of disorders.

Abstract
Genodermatoses are genetically inherited dermatologic conditions. The management of cutaneous findings in genodermatoses is challenging, and first-line therapies, such as steroids and/or retinoids, are often inadequate. In recent years, research on the molecular basis of genodermatoses has led to the use of biologic therapies for intractable disease. Here, we review the evidence regarding the use of available biologic therapies for the management of dermatologic findings in genodermatoses. Biologic therapies appear to be promising therapeutic options for several recalcitrant genodermatoses, especially those with underlying immune dysregulation. However, not all genodermatoses are amenable to biologic therapies, and some have been shown to paradoxically worsen under treatment. Biologic therapies offer a novel avenue to target refractory genodermatoses. However, evidence supporting the use of biologic therapies in the management of genodermatoses is mostly limited to case reports and case series. Further studies are warranted to determine the safety and efficacy of biologic therapies for the management of cutaneous findings in genodermatoses.
