Investigação de infecção tuberculosa latente em pacientes com psoríase candidatos ao uso de drogas imunobiológicas

Abstract: The use of tumor necrosis factor inhibitors for the treatment of patients with psoriasis has been related to a higher incidence of tuberculosis, specially the disseminated and extrapulmonary forms. Despite their efficacy, these drugs increase the risk of reactivating latent tuberculosis infection, thus requiring diagnosis of the condition before their administration. Investigation of latent tuberculosis infection with tuberculin skin test is ineffective due to its low specificity and the dubious results that i… Show more

“…35 However, their usage may be limited owing to the potential risk of LTBI reactivation in Pso patients, leading physicians to prefer more expensive IMB options, which subsequently increases the economic burden. 50 Furthermore, the PPD test has been shown to have limitations, most notably its low specificity in high BCG vaccine coverage scenarios and its reliance on patient immunocompetence for reliable results. Alternative tests, such as Interferon-Gamma Release Assays (IGRA), have been reported to be more specific, but their availability remains limited due to their high cost.…”

“…In patients with moderate to severe psoriasis, there is an overestimation of LTBI [ 44 ]. This would be explained by the intense skin inflammatory reaction of patients with moderate to severe psoriasis compared to others [ 45 , 46 , 47 ]. Although none of the patients in our study showed the reactivation of TB after oral prophylactic treatment with 9 HIN, several studies claim that this treatment does not give full protection [ 47 , 48 , 49 ], and the risk of aTB or LTBI is maintained during the biological treatment, especially with anti-TNF-α.…”

“…A associação da psoríase com acometimento articular e doenças intestinais inflamatórias (Doença de Crohn) foi demonstrada em diversos estudos 8,9 , geralmente com a psoríase precedendo sintomas intestinais 10 (há evidências da existência de um lócus imunomodulador capaz de influenciar as duas doenças) 1 . Controle conjunto das doenças pode ser difícil pela necessidade de droga que seja eficaz em ambas e que não seja capaz de interagir negativamente em uma das duas (por exemplo, o uso de corticosteroide sistêmico na Doença de Crohn é potencialmente capaz de provocar piora da psoríase).…”

“…Psoríase é uma dermatose inflamatória crônica, imunomediada, com predisposição genética, acometendo pele e articulações e afetando 2 a 4% da população ocidental 1 . Está associada a várias doenças sistêmicas, como hipertensão arterial, diabetes mellitus, obesidade e doença inflamatória intestinal (especialmente Doença de Crohn) 1 .…”
