Recent developments in the diagnosis, treatment, and management of Papillon-Lefèvre Syndrome.

DATA SOURCES: A systematic search of PubMed, LIVIVO, and Ovid was conducted up to March 2021. These databases were searched for relevant clinical studies on periodontal treatment success in individuals with Papillon-Lefèvre syndrome (PLS). STUDY SELECTION: Clinical studies reporting successful treatment outcomes defined as the loss of four or fewer permanent teeth due to periodontitis and the arrest of periodontitis or probing depths of 5 mm or less in individuals with PLS followed up for ≥24 months were included, and data extracted. DATA EXTRACTION AND SYNTHESIS: Twelve studies reporting on nine PLS patients met the inclusion criteria. The extracted main outcomes in the studies reporting successful periodontal treatment in PLS were as follows: (1) clinical and genetic diagnosis of PLS; (2) age at baseline; (3) initial dental, periodontal parameters, and microbiological assessment, if available; (4) description of disease progression and applied therapies; and (5) outcome and follow-up. RESULTS: Twelve studies reporting nine individuals were included. The timely extraction of affected or all primary teeth, compliance with oral hygiene instructions, supra- and subgingival debridement within frequent supportive periodontal care intervals, and adjunctive systemic antibiotic therapy in most patients affected a halt in disease progression. Suppression of Aggregatibacter actinomycetemcomitans below detection limits was associated with periodontal stabilization. CONCLUSIONS: An intensive, multidisciplinary approach with strict compliance may enable the decelerated progression of PLS-associated periodontitis. The early diagnosis of PLS and the suppression of A. actinomycetemcomitans below the detection level might be critical factors for treatment success. It required significant effort and patient compliance. The study emphasized the importance of timely interventions, oral hygiene maintenance, regular professional dental care, and, in some cases, systemic antibiotics.

Multidisciplinary management of Papillon-Lefevre syndrome as a result of consanguineous marriage.

Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive syndrome, and consanguinity has been reported in 20%-40% of cases. It is characterised by palmoplantar hyperkeratosis associated with severe early-onset periodontitis and premature loss of primary and permanent teeth. This report describes a case of PLS in a female patient with consanguineously married parents. The patient reported mobile upper front teeth. Clinical examination revealed presence of marked palmoplantar hyperkeratosis.Symmetric, well-demarcated, yellowish, keratotic and confluent plaques were seen on the skin of her palms and soles. Intraoral periodontal examination revealed erythematous gingiva with generalised periodontal pockets. Generalised mobility of teeth was present with clinically missing lower anterior teeth. Based on clinical and radiographic feature and the patient's medical, dental and family history, a diagnosis of PLS was made.

Two patients with Papillon-Lefèvre syndrome without periodontal involvement of the permanent dentition.

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive genodermatosis characterized by palmoplantar keratoderma and severe periodontitis leading to premature loss of primary and permanent teeth. PLS is caused by loss-of-function mutations in CTSC, lacking functional cathepsin C, which impairs the activation of neutrophil serine proteases. Precise pathogenesis of periodontal damage is unknown. Patient 1 presented with well-demarcated, transgredient, diffuse, palmoplantar keratoderma and psoriasiform lesions from the age of 2 years. Based on severe and recurrent periodontal inflammation, his dentist had diagnosed PLS at the age of 3 years and provided a strict oral hygiene regimen with repeated adjunct antibiotic therapies. Oral acitretin 10 mg/day along with tretinoin ointment at the age of 9 greatly improved palmoplantar keratoderma. Aged 18 years, the patient exhibited an intact permanent dentition and absence of periodontal disease. Patient 2, a 30-year-old man, suffered from transgredient, diffuse, palmoplantar keratoderma with fissuring from the age of 2 months, marked psoriasiform plaques on elbows and knees, and nail dystrophy. Intriguingly, without specific dental treatment, teeth and dental records were unremarkable. He was referred with a suspected diagnosis of psoriasis. Both patients were otherwise healthy, blood tests and sonography of internal organs were within normal limits. Panel sequencing revealed loss-of-function mutations in CTSC, c.322A>T (p.Lys108Ter) and c.504C>G (p.Tyr168Ter) in patient 1 and homozygous c.415G>T (p.Gly139Ter) in patient 2. The final diagnosis of unusual PLS was made. PLS should be considered in palmoplantar keratoderma lacking periodontitis or tooth loss.

Primary Immunodeficiencies With Defects in Innate Immunity: Focus on Orofacial Manifestations.

The field of primary immunodeficiencies (PIDs) is rapidly evolving. Indeed, the number of described diseases is constantly increasing thanks to the rapid identification of novel genetic defects by next-generation sequencing. PIDs are now rather referred to as "inborn errors of immunity" due to the association between a wide range of immune dysregulation-related clinical features and the "prototypic" increased infection susceptibility. The phenotypic spectrum of PIDs is therefore very large and includes several orofacial features. However, the latter are often overshadowed by severe systemic manifestations and remain underdiagnosed. Patients with impaired innate immunity are predisposed to a variety of oral manifestations including oral infections (e.g., candidiasis, herpes gingivostomatitis), aphthous ulcers, and severe periodontal diseases. Although less frequently, they can also show orofacial developmental abnormalities. Oral lesions can even represent the main clinical manifestation of some PIDs or be inaugural, being therefore one of the first features indicating the existence of an underlying immune defect. The aim of this review is to describe the orofacial features associated with the different PIDs of innate immunity based on the new 2019 classification from the International Union of Immunological Societies (IUIS) expert committee. This review highlights the important role played by the dentist, in close collaboration with the multidisciplinary medical team, in the management and the diagnostic of these conditions.

CTSC compound heterozygous mutations in two Chinese patients with Papillon-Lefèvre syndrome.

OBJECTIVES: To identify the molecular basis of Papillon-Lefèvre syndrome in two Chinese families. METHODS: Peripheral blood and mouth swab samples were obtained, from which genomic DNA and RNA were isolated. Sanger sequencing was employed to identify the mutations. mRNA expression was tested by real-time quantitative PCR. Evolutionary conservation, pathogenicity prediction and impact of protein structures of the mutations were conducted with bioinformatics tools and homology modelling. HEK293 cells were transfected with plasmids expressing wild-type or mutated CTSC. CTSC protein expression level and enzyme activity were explored. RESULTS: Mutation analysis revealed two novel compound heterozygous mutations, the c.190-191insA and c.1211-1212delA in patient 1 and the c.716A>G and c.757+1G>A in patient 2. In both patients, the levels of CTSC mRNA were significantly lower than in their relatives. Homology modelling analysis predicted that the mutations affect the structure and stability of the protein, and in vitro study showed that the CTSC proteins containing the mutations c.190-191insA and c.1211-1212delA, which result in truncated versions of protein, display impaired enzyme activity. The protein containing c.716A>G mutation showed quite similar enzyme activity compared to wild-type CTSC. CONCLUSION: Our data support the molecular mechanism of PLS and enlarge the scope of CTSC gene mutations related to PLS.

Full-Mouth Rehabilitation with Calvarium Bone Grafts and Dental Implants for a Papillon-Lefèvre Syndrome Patient: Case Report.

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder of keratinization associated with palmoplantar keratoderma and severe periodontitis resulting in complete edentulism in late adolescence. The pathognomonic dental features of PLS are pathologic migration, hypermobility, and exfoliation of the teeth without any signs of root resorption. It has been suggested that an effective way to treat PLS patients presenting early in the disease progression is extraction of the erupted primary dentition or hopeless permanent teeth followed by antibiotic coverage with periodontal therapy for the remaining teeth. Unfortunately, studies have shown that this regimen only temporarily delays the progression of periodontal disease and does not prevent further tooth loss and bone destruction in the long term. Post-tooth loss, atrophic ridges make conventional prosthodontic rehabilitation quite challenging, and more recently, implant-supported prostheses have been considered as a viable alternative. In a PLS patient, implant placement is complicated by inadequate bone volume; thus, bone augmentation techniques or the use of short implants is often considered. When large volumes of bone are required, parietal calvarium bone can be used to predictably reconstruct severe defects. A PLS patient aged 21 years presented a chief complaint of ill-fitting conventional complete dentures. The patient had severely atrophic ridges, requiring significant bone augmentation for an implant-supported prosthesis. The present case is the first example of bone augmentation using autogenous calvarium parietal graft followed by endosseous implant placement and prosthetic restoration in a PLS patient.

Ocular Surface Squamous Neoplasia in Papillon-Lefèvre Syndrome: Outcome at Long-Term Follow-Up of 12 Years.

PURPOSE: To discuss the association between ocular surface squamous neoplasia (OSSN) and Papillon-Lefèvre syndrome (PLS) and present the long-term outcome in a patient with these diseases. METHODS: Case report. RESULTS: A 14-year-old boy presented with a raised pigmented mass lesion at the limbus in the right eye, which was clinically suggestive of OSSN. He also had palmoplantar hyperkeratosis and periodontosis suggestive of PLS. Excision biopsy of the lesion confirmed the diagnosis of OSSN. He was free of tumor recurrence for 2 years and was lost to follow-up thereafter. Seven years later, the patient presented with diffuse tumor recurrence with orbital extension in the right eye, regional lymph node metastasis, and ipsilateral parotid gland infiltration. The patient underwent exenteration of the right orbital contents, right parotidectomy, and radical neck dissection followed by concomitant external beam radiotherapy and systemic chemotherapy. Eleven years from initial presentation, the patient was detected to have OSSN in the contralateral eye and was managed by wide excision biopsy and adjuvant cryotherapy. One year after detection of OSSN in the left eye, the patient was found to have systemic metastases to the lungs and brain. The patient died of the disease within 3 months of detection of systemic metastasis. CONCLUSIONS: OSSN in PLS is associated with poor prognosis.

Oro-dental characteristics of three siblings with Papillon-Lefevre syndrome.

Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive disorder, showing oral and dermatological manifestations in the form of aggressive periodontitis, leading to the premature loss of both primary and permanent teeth at a very young age and palmar-plantar hyperkeratosis. It was first described by two French physicians, Papillon and Lefevre in 1924. Immunologic, genetic, or possible bacterial etiologies have been thought to account for etiopathogenesis of PLS. Severe gingival inflammation and periodontal destruction occurred after the eruption of primary teeth. This condition should warn the physicians and dentists as a one of the important sign for the diagnosis of PLS. There have been over 250 cases reported in literature about PLS, but a few of these were in the same family. This study presents oro-dental characteristics, dental treatments, and follow-up of three siblings (age of sisters are 13, 6, and 4 years) with PLS, which is rarely seen in the same family.

Papillon-Lèfevre syndrome with palmoplantar keratoderma and periodontitis, a rare cause of pyrexia of unknown origin: a case report.

INTRODUCTION: Papillon-Lefèvre Syndrome is a rare autosomal recessive disorder characterized by diffuse, transgradient palmoplantar keratoderma, destructive periodontitis beginning in childhood, premature loss of primary teeth, and frequent cutaneous and systemic pyogenic infections. Pyogenic liver abscess is an uncommon presentation of the disease present in this case. CASE PRESENTATION: A 16-year-old Punjabi, Pakistani boy presented to the outpatient department of a tertiary-care hospital of Lahore with high-grade fever of 2 months duration. He had been treated for a pyogenic liver abscess 2 years back with antibiotics followed by incision and drainage. He had poor orodental hygiene, palmoplantar keratoderma and periodontitis. His parents had history of consanguinity. His brother and two cousins had similar skin lesions and were edentulous. An orthopentogram showed atrophy of the alveolar bone. He was treated with broad-spectrum antibiotics, and antipyretics for systemic infection. Multivitamins, topical steroids, topical keratolytics and emollients were used for his dermatological issues. CONCLUSIONS: Our patient was successfully treated. His fever settled and his skin lesions improved with antibiotics, topical steroids and keratolytics. He was sent home and was asked to return for follow-up on a monthly basis.

Systemic lupus erythematosus complicated with liver cirrhosis in a patient with Papillon-Lefèvre syndrome.

We report the first case of a girl who presented with Papillon-Lefèvre syndrome (PLS) and subsequently developed systemic lupus erythematosus and liver cirrhosis. This indicates that autoimmune diseases can be a complication in patients with PLS. Cathepsin C gene mutations were not found in our patient or her mother. Thus, other genetic factors may have been involved in this patient.

Papillon Lefevre Syndrome and footsteps of mycobacterium tuberculosis.

Papillon Lefevre Syndrome ( PLS ) is a very rare genetic syndrome that only less than 500 cases have reported in the world. Patients have a typical cutaneous involvement with hyperkeratosis especially on the soles and palms and early shedding of primary teeth. Internal organs involvement such as liver abscess has been presented as case reports. This is for the first time that a genetically documented PLS with footsteps of mycobacterium tuberculosis in liver and kidney will report.

Long-term results after treatment of periodontitis in patients with Papillon-Lefèvre syndrome: success and failure.

AIM: Retrospective evaluation of periodontal status in patients with Papillon-Lefèvre syndrome (PLS) observed for ≥10 years; identification of factors that may influence treatment outcome; and reporting of the outcome of dental implants in four PLS patients. METHODS: All PLS patients currently registered at the Department of Periodontology, Goethe-University Frankfurt with a follow-up ≥10 years (13-33 years; mean 22 years) were recruited. Eight patients (aged 17-46 years) from five families (three pairs of siblings) were included. RESULTS: After comprehensive periodontal therapy in eight PLS patients, teeth were retained in only two. In six patients, all teeth were extracted, almost entirely due to periodontal reasons. In four patients, teeth were prosthodontically restored with implants. Currently, three patients already show peri-implantitis. CONCLUSIONS: In some PLS patients, periodontitis may be arrested by: combined mechanical and antibiotic periodontal treatment; extraction of severely diseased teeth; oral hygiene instructions; intensive maintenance therapy; and microbiological monitoring and treatment of the infection with Aggregatibacter actinomycetemcomitans. Implants in PLS patients who did not follow any maintenance programme have a high risk of peri-implantitis and implant loss. Treatment of PLS patients has always to be considered as high-risk cases.

Multiple cerebral abscesses in Papillon-Lefèvre syndrome.

Papillon-Lefèvre syndrome is characterised by palmoplantar keratoderma, periodontitis and pyogenic infections. We describe the first case of brain abscess in a child with this syndrome. We highlight the importance of recognising any associated diagnosis, however rare or apparently irrelevant, in an acutely and critically ill child.

Papillon-Lefèvre syndrome in 2 siblings: case report after 11-year follow-up.

The purpose of this case report was to describe the clinical long-term outcome, 11 years after periodontal therapy, of 2 siblings diagnosed with Papillon-Lefèvre syndrome. Sibling 1 was a 14-year-old boy with severe periodontal bone loss in his permanent dentition. Sibling 2 was a 7-year-old girl with mixed-dentition and also suffering from periodontal disease. Both were treated with a combination of nonsurgical and antimicrobial therapy. Annual re-evaluations were performed for 11 years. Both siblings improved their periodontal status, but a low level of compliance with treatment over time by sibling 1 resulted in further tooth loss and recurrent periodontal disease. Sibling 2 experienced good periodontal healing in her primary and, later, permanent teeth due in part to proper compliance with oral hygiene instructions. Periodontal health was achieved, and no tooth loss occurred during follow-up. Papillon-Lefèvre syndrome subjects can be successfully treated with nonsurgical/antimicrobial therapy, but treatment outcome could be related to age at diagnosis and compliance with oral hygiene procedures.

Initial expression of the Papillon-Lefevre syndrome in consanguine family.

A rare case of Papillon-Lefevre syndrome is discussed with clinicoradiological presentation. The purpose of the case report is to make the medical community aware of this rare syndrome and its association with consanguinity. Papillon-Lefevre syndrome is an extremely rare genodermatosis of autosomal-recessive inheritance which usually manifests itself between the ages of 6 months to 4 years characterised by diffuse palmoplanter hyperkeratosis (keratoderma), and rapidly progressive and devastating periodontitis, affecting the primary as well as permanent dentition. Papillon-Lefevre syndrome results from a combination of host and bacterial factors, including recessive gene, consanguinity, specific periodontal pathogens and lack of thorough oral hygiene. The present case report describes Papillon-Lefevre syndrome and its association with consanguinity in a 3-year-old girl.

Periodontal diseases in children and adolescents: a clinician's perspective part 2.

UNLABELLED: The general dental practitioner and paediatric dentist are in a unique position to identify and distinguish between a seemingly innocuous condition that may be a normal physiological aberration or an early sign of severe destructive periodontal disease. Although severe destructive periodontal conditions are uncommon in children, it is essential that children receive a periodontal screening as part of their regular dental examination. Early diagnosis ensures a high likelihood of a successful therapeutic outcome, primarily by reduction of aetiologic factors, remedial therapy and development of an effective maintenance protocol. This prevents the recurrence and progression of disease and reduces the incidence of tooth loss. In the first article, we discussed the classification, plaque-induced and non plaque-induced gingival diseases, localized and generalized forms of chronic as well as aggressive periodontitis. In this second article, we discuss periodontitis as a manifestation of systemic disease, necrotizing periodontal diseases, periodontal screening and basic periodontal examination, and treatment of periodontal diseases in children and adolescents. CLINICAL RELEVANCE: Incorporation of periodontal screening in regular dental examination by dentists can help in early diagnosis and treatment of periodontal diseases. This could prevent further progression of disease and reduce the frequency of tooth loss.

Papillon-Lefevre syndrome.

Papillon-Lefevre syndrome is a very rare syndrome of autosomal recessive inheritance characterized by palmoplanter hyperkeratosis of the skin and severe periodontal disease extending to destruction of the alveolar bone surrounding deciduous and permanent teeth as they erupt leading to precocious loss of dentition. Although the exact pathogenesis of this syndrome is still unknown immunologic, microbiologic, and genetic bases have been proposed. Here we report a case of Papillon-Lefevre syndrome. The patient had generalized plaque accumulation along with halitosis, mobile teeth with periodontal pocket with pus exudation. Blood & biochemical report was within normal limit with a low CD3+ and CD4+.

Full-mouth rehabilitation of an edentulous patient with Papillon-Lefèvre syndrome using dental implants: a clinical report.

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder. The oral manifestations of the syndrome include rapidly progressive periodontal disease resulting in premature exfoliation of primary and permanent dentitions. Patients are often edentulous at an early age and require prosthodontic treatment. This report is the oral rehabilitation of an edentulous 21-year-old woman with PLS. Treatment included maxillary and mandibular fixed prostheses supported by osseointegrated dental implants. At the 4-year follow-up, the patient presented significant improvements in oral function and psychosocial activities and no prosthetic complications.
