Abstract
BACKGROUND Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering disease of the skin and mucous membranes. This disease typically affects the elderly and presents with itch and localized or, most frequently, generalized bullous lesions. A subset of patients only develops excoriations, prurigo-like lesions, and eczematous and/or urticarial erythematous lesions. The disease, which is significantly associated with neurological disorders, has high morbidity and severely impacts the quality of life. OBJECTIVES AND METHODOLOGY The Autoimmune blistering diseases Task Force of the European Academy of Dermatology and Venereology sought to update the guidelines for the management of BP based on new clinical information, and new evidence on diagnostic tools and interventions. The recommendations are either evidence-based or rely on expert opinion. The degree of consent among all task force members was included. RESULTS Treatment depends on the severity of BP and patients' comorbidities. High-potency topical corticosteroids are recommended as the mainstay of treatment whenever possible. Oral prednisone at a dose of 0.5 mg/kg/day is a recommended alternative. In case of contraindications or resistance to corticosteroids, immunosuppressive therapies, such as methotrexate, azathioprine, mycophenolate mofetil or mycophenolate acid, may be recommended. The use of doxycycline and dapsone is controversial. They may be recommended, in particular, in patients with contraindications to oral corticosteroids. B-cell-depleting therapy and intravenous immunoglobulins may be considered in treatment-resistant cases. Omalizumab and dupilumab have recently shown promising results. The final version of the guideline was consented to by several patient organizations. CONCLUSIONS The guidelines for the management of BP were updated. They summarize evidence- and expert-based recommendations useful in clinical practice.

European guidelines (S3) on diagnosis and management of mucous membrane pemphigoid, initiated by the European Academy of Dermatology and Venereology - Part I. J Eur Acad Dermatol Venereol 2021; 35:1750-1764. [PMID: 34245180 PMCID: PMC8457055 DOI: 10.1111/jdv.17397] [Citation(s) in RCA: 54] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Accepted: 05/17/2021] [Indexed: 12/15/2022]
Abstract
This guideline on mucous membrane pemphigoid (MMP) has been elaborated by the Task Force for Autoimmune Blistering Diseases of the European Academy of Dermatology and Venereology (EADV) with a contribution of physicians from all relevant disciplines and patient organizations. It is a S3 consensus-based guideline encompassing a systematic review of the literature until June 2019 in the MEDLINE and EMBASE databases. This first part covers methodology, the clinical definition of MMP, epidemiology, MMP subtypes, immunopathological characteristics, disease assessment and outcome scores. MMP describes a group of autoimmune skin and mucous membrane blistering diseases, characterized by a chronic course and by predominant involvement of the mucous membranes, such as the oral, ocular, nasal, nasopharyngeal, anogenital, laryngeal and oesophageal mucosa. MMP patients may present with mono- or multisite involvement. Patients' autoantibodies have been shown to be predominantly directed against BP180 (also called BPAG2, type XVII collagen), BP230, laminin 332 and type VII collagen, components of junctional adhesion complexes promoting epithelial stromal attachment in stratified epithelia. Various disease assessment scores are available, including the Mucous Membrane Pemphigoid Disease Area Index (MMPDAI), the Autoimmune Bullous Skin disorder Intensity Score (ABSIS), the 'Cicatrising Conjunctivitis Assessment Tool' and the Oral Disease Severity Score (ODSS). Patient-reported outcome measurements (PROMs), including DLQI, ABQOL and TABQOL, can be used for assessment of quality of life to evaluate the effectiveness of therapeutic interventions and monitor disease course.

Feline allergic diseases: introduction and proposed nomenclature. Vet Dermatol 2021; 32:8-e2.

Abstract
BACKGROUND Feline allergic diseases present as challenging problems for clinicians, not least because of the number of reaction patterns of the feline skin, none of which are specific for allergy. Furthermore, there is some controversy over the nomenclature that should be used in their description. OBJECTIVES To review the literature, assess the status of knowledge of the topic and the extent to which these diseases could be categorized as atopic in nature, and make recommendations concerning nomenclature. METHODS Atopic diseases in humans and cats were researched. A comparison then was made of the essential features in the two species. RESULTS There were sufficient similarities between human atopic diseases and the manifestations of feline diseases of presumed allergic aetiology to justify the use of "atopic" to describe some of the feline conditions affecting the skin, respiratory and gastrointestinal tract. However, none of the allergic skin diseases showed features consistent with atopic dermatitis as described in man and the dog. CONCLUSIONS AND CLINICAL IMPORTANCE The term "Feline Atopic Syndrome" (FAS) is proposed to encompass allergic diseases of the skin, gastrointestinal tract and respiratory tract, and "Feline atopic skin syndrome" (FASS) proposed to describe allergic skin disease associated with environmental allergies. We are not aware of any adverse food reactions in cats that are attributable to causes other than immunological reactions against the food itself. We therefore propose an aetiological definition of "Food Allergy" (FA) to describe such cases.

Abstract
Bronchoalveolar lavage, or BAL, is a minimally invasive procedure frequently used for clinical and non-clinical research, allowing studies of the respiratory system. Macaques are the most widely used non-human primate models in biomedical research. However, very little information is available in the literature concerning BAL cytology in macaques. The purpose of this study was to establish BAL reference values and document an atlas of BAL cytology from healthy cynomolgus macaques. BALs were obtained from 30 macaques and BAL fluid differential cell counts based on 400 nucleated cells/BAL sample were performed by a board-certified clinical pathologist. Results were analyzed using Reference Value Advisor macroinstructions and the effect of blood and oropharyngeal contaminations was investigated. Overall, nucleated cells interval percentages in BAL fluids were 55.8 to 93.7 for macrophages, 1.8 to 37.1 for lymphocytes, 0.4 to 8.7 for neutrophils, and 0.4 to 9.8 for eosinophils. Mild oropharyngeal contamination did not affect BAL differential cell counts, whilst a slight but significant increase of the percentage of lymphocytes was observed in samples with mild blood contamination. Mucus and variable numbers of ciliated epithelial cells were commonly present. Rarely, multinucleated macrophages and mastocytes were also observed. The reference intervals established in this study provide a useful baseline for the assessment of BAL cytological data in cynomolgus macaques.

Abstract
BACKGROUND The use of concurrent medications is necessary in trials of treatment of canine atopic dermatitis. Our aim was to use the best available evidence to construct and then to validate a medication score (MS) formula that will estimate the impact of concurrent medications on trial outcomes. METHODS Trials of 15 interventions were scrutinized to find those that were consistent in terms of specific medication, administration route and dosage regimen. A MS was constructed in five steps, starting from assigning a score of 1 for each day on oral prednisone, prednisolone or methylprednisolone at 0.5-1.0 mg/kg. The MS score was validated using the clinical records of 35 dogs with atopic dermatitis that had been treated for a period of 12 ± 2 weeks with six of these medications and compared with a previously published non-validated MS. RESULTS A MS could be assigned to eight treatments, six of which had been administered to the 35 dogs. A positive correlation was seen with the previously published MS and a negative correlation with changes in lesional and pruritus scores. CONCLUSION This MS may be a useful tool in new studies evaluating the efficacy of treatments in canine atopic dermatitis.

Abstract
BACKGROUND Feline allergic skin disease and asthma occur regularly in small animal practice. OBJECTIVES To provide evidence-based recommendations for small animal practitioners on the treatment of feline atopic syndrome (FAS). METHODS AND MATERIALS The authors reviewed the literature available before February 2020, prepared a detailed evidence-based literature review and made recommendations based on the evaluated evidence. RESULTS Sixty-six papers and abstracts were identified describing treatment interventions for FAS and evaluated to establish treatment recommendations. For many treatment options, the papers were retrospective, open studies or case reports. CONCLUSION AND CLINICAL RELEVANCE In this review, there was good evidence for the efficacy of systemic glucocorticoids and ciclosporin, and limited evidence for the efficacy of topical glucocorticoids, oclacitinib and allergen-specific immunotherapy in feline atopic skin syndrome. Evidence pointed to low-to-moderate efficacy for antihistamines, fatty acids and palmitoyl ethanolamide. In feline asthma, there was good evidence for the efficacy of oral and inhaled glucocorticoids, and limited evidence of moderate efficacy for allergen-specific immunotherapy. Evidence supported low-to-moderate efficacy of mesenchymal stem cells, inhaled lidocaine and oclacitinib as treatments for feline asthma. For almost all therapeutic options (with the exception of glucocorticoids and ciclosporin), more randomised controlled trials are needed.

Clinical signs and diagnosis of feline atopic syndrome: detailed guidelines for a correct diagnosis. Vet Dermatol 2021; 32:26-e6.

Abstract
BACKGROUND Feline atopic syndrome (FAS) describes a spectrum of hypersensitivity disorders characterised by highly diverse clinical presentations including skin, gastrointestinal and respiratory systems. Among these disorders is feline atopic skin syndrome (FASS), in which hypersensitivity is typically associated with environmental allergens, although food allergy may coexist. Involvement of other organ systems (e.g. asthma) also may occur. Because of its highly heterogeneous clinical presentation, diagnosis of FASS can be challenging. OBJECTIVES A subgroup of the International Committee on Allergic Diseases of Animals was tasked to summarise the most current information on the clinical presentations of FASS and to develop diagnostic guidelines. METHODS AND MATERIALS Online citation databases and abstracts from international meetings were searched for publications related to feline allergic conditions. These were combined with expert opinion where necessary. RESULTS A total of 107 publications relevant to this review were identified. Compilation of these data enabled development of a detailed description of the clinical features of FASS and development of guidelines focusing on systematic elimination of other skin conditions with similar clinical characteristics. As allergen tests are frequently used by dermatologists to support a clinical diagnosis of FASS, a brief review of these methodologies was also performed. CONCLUSIONS AND CLINICAL IMPORTANCE In a similar way to atopic dermatitis in dogs, FASS is a clinical diagnosis based on the presence of compatible clinical signs and exclusion of other diseases with similar clinical features. Elimination or exclusion of fleas/flea allergy, other parasites, infections and food allergy is mandatory before reaching a diagnosis of FASS.

Abstract
Despite continuous advances in analytical and physiological knowledge, the comprehension of an aroma is still a challenge. Gas chromatography coupled to olfactometry (GC-O) is an efficient method to identify and estimate individual potential of odorants, but there is a gap between this individual characterization and the effective contribution of compounds in the mixture, which is due to complex chemical and perceptual interactions. Therefore, recombination and omission experiments are often performed to achieve an understanding of food aromas. In this study, a chromatographic device, developed to facilitate aroma analysis, is presented. It was configured to perform both (1) conventional analyses by GC coupled with a mass spectrometer, olfactometric port(s), and a flame ionization detector (FID), and (2) omission or recombination experiments. This dual capability is due to the singular configuration of the system using an ingenious combination of splitter and Deans switch microfluidics transfer modules, and the existence of multiple outlets. The operational status of the system was tested using a purposely simple mixture of compounds. The similarity of retention times (RT) and FID peak areas obtained for each outlet demonstrates that the multiple outlets of the system are equivalent. The reproducibility of retention times (RT) and FID peak areas obtained in switching and non-switching conditions, also demonstrates the efficiency of switching operations. The validation of the system enables multiple detectors to be connected to the outlets and complementary information can be obtained from the eluate. The connection of recovery disposals to the outlets provides fraction collection and recombination possibilities, which contribute much to the understanding of aroma-aroma interactions. As an illustration of the InnOscent system relevance for the comprehension of more complex aromas, the device was used to study the aroma of a wine made from Cabernet Franc grape variety. An olfactometric profile was efficiently produced with the device configured as a GC-MS coupled to a dual olfactometric port. The main odorant active compounds were identified. The omission approach, carried out with the system on isopropyl- and isobutyl-methoxypyrazines, demonstrates the significant contribution of these compounds to the aroma of the wine studied, despite an individual perception among the weakest of the aromagram. A similar approach can be used to evaluate the contribution of any compound to any aroma. This approach overcomes constraints of current methodologies associated to reconstituted model solutions and paves the way for a better understanding of aroma construction.

Abstract
Background Ciclosporin and oclacitinib are immunomodulators approved for the treatment of canine atopic dermatitis. The administration of a short course of prednisolone at the beginning of ciclosporin therapy hastens the efficacy of this drug; oclacitinib has a rapid antipruritic effect similar to that of prednisolone. Objectives To evaluate the oral tolerance of oclacitinib and ciclosporin given concurrently for three weeks. Animals Two groups of eight beagles. Methods Dogs were randomized to receive oclacitinib alone (0.4–0.6 mg/kg twice daily for 14 days then once daily for seven days) or in combination with ciclosporin (5 mg/kg once daily) for three weeks. They were examined every day and adverse events were recorded. Blood samples were collected during the acclimatization phase, weekly during treatment and at the end of the study for haematology, clinical chemistry and coagulation evaluation. Results There were no abnormal clinical observations following treatment with oclacitinib given alone or concomitantly with ciclosporin, with the exception of diarrhoea in two dogs receiving both drugs. Three dogs from each group experienced transient inappetence; three dogs treated with oclacitinib had mild weight loss. Clinical pathology parameters remained within the reference range for beagle dogs at that facility. Conclusions and clinical importance The concomitant administration of ciclosporin and oclacitinib for three weeks to beagles was well tolerated and was not associated with an increase in the number of adverse events or laboratory abnormalities beyond those associated with oclacitinib given alone. Background – Ciclosporin and oclacitinib are immunomodulators approved for the treatment of canine atopic dermatitis. The administration of a short course of prednisolone at the beginning of ciclosporin therapy hastens the efficacy of this drug; oclacitinib has a rapid antipruritic effect similar to that of prednisolone. Objectives–To evaluate the oral tolerance of oclacitinib and ciclosporin given concurrently for 3 weeks. Conclusions and clinical importance–The concomitant administration of ciclosporin and oclacitinib for 3 weeks to beagles was well tolerated and was not associated with an increase in the number of adverse events or laboratory abnormalities beyond those associated with oclacitinib given alone.

Pneumonia due to Mycobacterium malmoense is rare and usually occurs in damaged lung as is the case with Aspergillus infections. We report the case of a patient who developed chronic necrotizing pulmonary aspergillosis following an infection by atypical mycobacteria. A 53-year-old woman was hospitalized because of weight loss and fever. Direct examination of sputum smear was positive for acid fast bacilli and PCR and culture led to the diagnosis of infection with M. malmoense. Treatment was begun with clarithromycin, rifampicin and ethambutol. Despite initial improvement and excellent adherence to treatment, fever and weight loss recurred 6 months later. Relapse of the mycobacterial infection was excluded and the final diagnosis was necrotizing pulmonary aspergillosis. Infection with A. fumigatus complicating the treatment of M. malmoense is unusual. The management is challenging because of strong interactions between voriconazole and rifampicin, and thus requires a multidisciplinary and specialized approach.

Abstract
BACKGROUND COL4A1 mutations cause familial porencephaly, infantile hemiplegia, cerebral small vessel disease (CSVD), and hemorrhagic stroke. We recently described hereditary angiopathy with nephropathy, aneurysm, and muscle cramps (HANAC) syndrome in 3 families with closely localized COL4A1 mutations. The aim of this study was to describe the cerebrovascular phenotype of HANAC. METHODS Detailed clinical data were collected in 14 affected subjects from the 3 families. MRI and magnetic resonance angiography (MRA) were performed in 9 of them. Skin biopsies were analyzed by electron microscopy in affected subjects in the 3 families. RESULTS Only 2 of 14 subjects had clinical cerebrovascular symptoms: a minor ischemic stroke at age 47 years and a small posttraumatic hemorrhage under anticoagulants at age 48 years. MRI-MRA showed cerebrovascular lesions in 8 of 9 studied subjects (mean age 39.4 years, 21-57 years), asymptomatic in 6 of them. Unique or multiple intracranial aneurysms, all on the carotid siphon, were observed in 5 patients. Seven patients had a CSVD characterized by white matter changes (7/7) affecting subcortical, periventricular, or pontine regions, dilated perivascular spaces (5/7), and lacunar infarcts (4/7). Infantile hemiplegia, major stroke, and porencephaly were not observed. Skin biopsies showed alterations of basement membranes at the dermoepidermal junction associated with expansion of extracellular matrix between smooth vascular cells in the arteriolar wall. CONCLUSION The cerebrovascular phenotype in hereditary angiopathy with nephropathy, aneurysm, and muscle cramps syndrome associates a cerebral small vessel disease and a large vessel disease with aneurysms of the carotid siphon. It is consistent with a lower susceptibility to hemorrhagic stroke than in familial porencephaly, suggesting an important clinical heterogeneity in the phenotypic expression of disorders related to COL4A1 mutations.

Abstract
INTRODUCTION Bullous pemphigoid usually affects elderly people. Only a few isolated cases among people younger than 65 years have been reported. OBJECTIVES Describe the clinical and biological characteristics of patients younger than 60 years suffering from bullous pemphigoid, compare them with the usual characteristics known among elderly people and search for potential pathological associations. PATIENTS AND METHODS Retrospective, national, multicenter study. Clinical, biological and histological characteristics were recorded with a standardised questionnaire as well as treatments and associated pathologies. RESULTS Seventy-four cases of bullous pemphigoid diagnosed between June 1970 and March 2002 were analyzed. Mean age at the beginning of the disease was 46 +/- 11.6 years. Further explorations by indirect immunofluorescence of separated skin and/or immuno-electron microscopy and/or immunoblotting were performed for 42 patients (56.8 p. 100). Clinical characteristics among this restricted population were comparable to those found among the 32 other cases. Compared to usual data on bullous pemphigoid in elderly people, we observed a greater proportion of extensive form of disease (75 p. 100), a more frequent head and neck involvement (39.2 p. 100) and an overexpression of anti-BP180 autoantibodies (48 p. 100). Neoplasm was notified for 7 patients (9.5 p. 100), 18 (24.3 p. 100) suffered from a pathology of the basement membrane zone (6 psoriasis, 6 atopic dermatitis and 6 lichen) and 13 from neurological disease, among which 4 were bedridden. Fourty-six patients (62.2 p. 100) received drugs for the long term (mean 2.12 +/- 2.43), 4 patients were treated by PUVAtherapy and 2 by radiotherapy. DISCUSSION Our results suggest that bullous pemphigoid among young people is more severe and more active than the usual form in the elderly. This particular form could be the result of a higher expression of anti-BP180 autoantibodies, which are considered as a marker of poor prognosis in this disease. We also found a high frequency of pathological associations and physical treatment, all responsible for damage to the basement membrane zone, which can involve auto-immunization against hemidesmosome components.
