Long-term successful treatment of a donkey with cutaneous lupus erythematous with methotrexate.
Abstract: Cutaneous lupus erythematosus (CLE) is a rare immune-mediated dermatitis. To the best of the authors' knowledge it has not been described in donkeys. A 5-year-old male neutered donkey, living in south-east France, was diagnosed with CLE. Clinical signs included generalized symmetrical areas of alopecia, erythema, crusting and scales. Diagnostic tests included examination of skin biopsy samples by histopathological and immunohistochemical analysis which demonstrated an interface dermatitis with CD8+ T cells. The skin condition was successfully treated initially with glucocorticoids and methotrexate; successful long-term maintenance was associated with administration of methotrexate. Le lupus cutané érythémateux (CLE) est une dermatite à médiation immune rare. A la connaissance des auteurs, il n’a pas été décrit chez le singe. Un singe mâle castré de 5 ans, vivant dans le sud-est de la France a été diagnostiqué avec CLE. Les signes cliniques incluaient des zones symétriques généralisées d’alopécie, d’érythème, de croûtes et de pellicules. Les tests diagnostics comprenaient un examen histopathologique et immunohistochimique de biopsies cutanées qui ont révélé une dermatite d’interface avec cellules T CD8+. La dermatose a été traitée avec succès initialement avec des corticoïdes et du méthotrexate; un traitement efficace au long cours a été associé avec l’administration de méthotrexate. El lupus eritematoso cutáneo (CLE) es una rara dermatitis inmunomediada. A entender de los autores, esta enfermedad no se ha descrito en burros. Un burro castrado macho de 5 años de edad, que vive en el sureste de Francia fue diagnosticado con CLE. Los signos clínicos incluyeron áreas simétricas generalizadas de alopecia, eritema, costras y escamas. Las pruebas de diagnóstico incluyeron el examen de muestras de biopsia de piel mediante análisis histopatológico e inmunohistoquímico que demostró una dermatitis de interfase con células T CD8+. La condición de la piel se trató con éxito inicialmente con glucocorticoides y metotrexato; el control exitoso a largo plazo de la enfermedad se obtuvo con la administración de metotrexato. Der kutane Lupus erythematosus (CLE) ist eine seltene immun-mediierte Dermatitis. Nach bestem Wissen der Autoren wurde sie bisher bei Eseln nicht beschrieben. Ein 5-Jahre alter männlicher kastrierter Esel, der im Südosten von Frankreich lebte wurde mit CLE diagnostiziert. Die klinischen Symptome bestanden aus generalisierten symmetrischen Arealen von Alopezie, Erythem, Krusten und Schuppen. Die diagnostischen Tests bestanden aus eine Untersuchung von Hautbiopsieproben mittels histopathologischer und immunhistochemischer Analyse, die eine Interface Dermatitis mit CD8+ T Zellen zeigte. Die Hauterkrankung wurde anfangs erfolgreich mit Glukokortikoiden und Methotrexat behandelt; eine erfolgreiche Erhaltungstherapie bestand in der Verabreichung von Methotrexat. 皮膚エリテマトーデス(CLE)は、まれな免疫介在性皮膚炎である。 著者の知る限り、ロバにおける記載はない。 フランス南東部の5歳、去勢雄のロバがCLEと診断された。 臨床徴候には、汎発性、左右対称性の脱毛、紅斑、痂皮および鱗屑を含んだ。 診断テストには、組織病理学的および免疫組織化学的分析による皮膚生検サンプルの検査を含に、CD8 + T細胞との境界部皮膚炎が示された。 皮膚コンディションには、グルココルチコイドおよびメトトレキサートによる初期治療が奏功した。 長期維持の成功には、メトトレキサートの投与が関連していた。. 皮肤红斑狼疮 (CLE) 是一种罕见的免疫介导性皮炎。据作者所知, 尚未有关于驴的相关报道。一只5岁的雄性去势驴, 生活在法国东南部, 被诊断为CLE。临床症状包括全身对称性脱毛、红斑、结痂和鳞屑。诊断试验包括组织病理学和免疫组化, 对皮肤活检样本进行检查, 证明存在CD8+T细胞性界面性皮炎。初期使用糖皮质激素和甲氨蝶呤成功治疗了皮肤疾病;成功的长期维持与甲氨蝶呤给药有关。. O lúpus eritematoso cutâneo (LEC) é uma dermatite imunomediada rara. De acordo com os conhecimentos do autor, a doença ainda não foi descrita em jumentos. Um jumento macho castrado de cinco anos de idade, habitante do sul da França, foi diagnosticado com LEC. Os sinais clínicos incluíram alopecia, eritema, crostas e descamação generalizadas e simétricas. Os testes diagnósticos utilizados foram avaliação de amostras de biópsia por análise histopatológica e imunohistoquímica, que demonstraram dermatite de interface com células T CD8+. A dermatopatia foi tratada satisfatoriamente inicialmente com glicocorticoide e metotrexato; a manutenção satisfatória a longo prazo foi associada à administração de metotrexato.

This research successfully treated a donkey diagnosed with Cutaneous lupus erythematosus (CLE) using glucocorticoids and methotrexate. This is a significant case as CLE has never been reported in donkeys before.
Cutaneous Lupus Erythematosus in a Donkey
- The subject of the study was a 5-year-old neutered male donkey living in the southeastern region of France.
- The donkey presented with symptoms including generalized symmetrical bald patches (alopecia), redness of the skin (erythema), crusted skin, and scaly skin. These clinical signs led to the suspicion of an immune-mediated skin condition, potentially Cutaneous Lupus Erythematosus (CLE).
- CLE is a rare immune-mediated dermatitis that has not been reported in donkeys previously, to the best of the authors’ knowledge.
Diagnosing Cutaneous Lupus Erythematosus
- To confirm the suspected diagnosis, various diagnostic tests were carried out.
- These involved examination of skin biopsy specimens through both histopathological and immunohistochemical analyses.
- The results showed an interface dermatitis with CD8+ T cells, confirming the diagnosis of CLE in the donkey. Interface dermatitis involves inflammation where the epidermis (outer layer of the skin) meets the dermis (inner layer).
Treating Cutaneous Lupus Erythematosus
- Initial treatment for the skin condition involved administration of glucocorticoids and methotrexate. Glucocorticoids are a type of corticosteroid that reduces inflammation. Methotrexate is commonly used to treat cancer and autoimmune diseases, such as rheumatoid arthritis and psoriasis.
- Long-term management of the condition was maintained successfully by administering methotrexate. This suggests that methotrexate could be considered a viable long-term treatment option for donkeys diagnosed with CLE.
Significance of the Research
- The study documents the successful long-term treatment of CLE in a donkey. It also provides evidence that methotrexate can effectively manage the condition.
- The results serve as a helpful reference for veterinary practices dealing with similar equine cases.
