RESUMO
ABSTRACT Objective: To highlight the inflammatory and immunological mechanisms involved in depression and psoriasis. Methods: A comprehensive literature search was performed in various databases, in total 145 studies were selected. Results: Depression and psoriasis have an association. Immune mechanisms -the actions of tumor necrosis factor-a, interleukin 1 (IL-1), IL-2, IL-10, IL-22, IL-17, interferon-7, IL-1ß, prostaglandin E2, C-reactive protein, IL-6, and IL-8 etc.-, and some genetic changes are involved. Conclusions: A possible bidirectional relationship of psoriasis and major depression exists; i.e. the depression leads to psoriasis, and psoriasis leads to depression. We recommend more studies in the future to get a deeper and better understanding about this relationship.
RESUMEN Objetivo: Poner de relieve los mecanismos inflamatorios e inmunológicos involucrados en la depresión y la psoriasis. Métodos: Se realizó en varias bases de datos una búsqueda bibliográfica completa; en total se incluyeron 145 estudios. Resultados: Hay asociación entre depresión y psoriasis y están involucrados mecanismos inmunitarios -las acciones del factor de necrosis tumoral alfa, las interleucinas (IL) 1, 2, 10, 22 y 17, el interferón gamma, la IL-1ß, la prostaglandina E2, la proteína C reactiva, la IL-6 y la IL-8, etc. - y algunos cambios genéticos. Conclusiones: Hay una posible relación bidireccional entre psoriasis y depresión, es decir, la depresión lleva a psoriasis y la psoriasis lleva a depresión. Se recomiendan más estudios en el futuro para obtener una comprensión más profunda y mejor sobre esta relación.

Immune mechanisms -the actions of tumor necrosis factor-α, interleukin 1 (IL-1), IL-2, IL-10, IL-22, IL-17, interferon-γ, IL-1ß, prostaglandin E2, C-reactive protein, IL-6, and IL-8 etc.-, and some genetic changes are involved. CONCLUSIONS: A possible bidirectional relationship of psoriasis and major depression exists; i.e. the depression leads to psoriasis, and psoriasis leads to depression.

OBJECTIVE: The aim of this paper was to highlight the mechanisms involved and the relationship between depression and psoriasis. METHOD: A comprehensive literature search was performed in various databases, and finally 88 studies were deemed relevant. RESULTS: A significant link was found between depression and psoriasis, primarily through immune mechanisms related but not limited to the actions of inflammatory cytokines such as tumor necrosis factor-α, interleukin 1 (IL-1), IL-2, IL-10, interferon-γ, IL-1ß, prostaglandin E2, C-reactive protein, IL-6, and IL-8. CONCLUSION: Various neuroimmunological studies point towards the notion that depression and psoriasis are associated with each other. Melatonin has also been found to be associated with both conditions. A possibility exists that both conditions can cause each other due to the possible bidirectional relationship of psoriasis and major depression. However, if this is the case, then why all depressed patients fail to develop psoriasis and why all psoriatic patients fail to develop depression remains a question unanswered. We believe that future studies will unmask this mystery.
