AI Article Synopsis
- * Out of 89 patients analyzed, 57 experienced dermatological reactions, with a significant association found between grade 3 reactions and male sex, as well as elevated serum granulysin levels.
- * The findings suggest that higher serum granulysin levels correlate with more severe reactions, indicating potential for using these levels as a predictive measure for assessing risk in patients receiving telaprevir therapy.
Article Abstract
Aim: Telaprevir-based therapy for chronic hepatitis C patients is effective; however, the high prevalence of dermatological reactions is an outstanding issue. The mechanism and characteristics of such adverse reactions are unclear; moreover, predictive factors remain unknown. Granulysin was recently reported to be upregulated in the blisters of patients with Stevens-Johnson syndrome (SJS). Therefore, we investigated the risk factors for severe telaprevir-induced dermatological reactions as well as the association between serum granulysin levels and the severity of such reactions.
Methods: A total of 89 patients who received telaprevir-based therapy and had complete clinical information were analyzed. We analyzed the associations between dermatological reactions and clinical factors. Next, we investigated the time-dependent changes in serum granulysin levels in five and 14 patients with grade 3 and non-grade 3 dermatological reactions, respectively.
Results: Of the 89 patients, 57 patients had dermatological reactions, including nine patients with grade 3. Univariate analysis revealed that grade 3 dermatological reactions were significantly associated with male sex. Moreover, serum granulysin levels were significantly associated with the severity of dermatological reactions. Three patients with grade 3 dermatological reaction had severe systemic manifestations including SJS, drug-induced hypersensitivity syndrome, and systemic lymphoid swelling and high-grade fever; all were hospitalized. Importantly, among the three patients, two patients' serum granulysin levels exceeded 8 ng/mL at onset and symptoms deteriorated within 6 days.
Conclusion: Male patients are at high risk for severe telaprevir-induced dermatological reactions. Moreover, serum granulysin levels are significantly associated with the severity of dermatological reactions and may be a predictive factor in patients treated with telaprevir-based therapy.

The overlap of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) and Stevens-Johnson syndrome (SJS) caused by antituberculosis drugs represents an extremely rare event. This situation can manifest between 2 and 8 weeks after the first exposure to the medication. The overlap of these conditions can lead to atypical clinical manifestations, thus complicating the early diagnosis and the implementation of early treatment.

Vaccination is a fundamental principle of preventive health care. Administration of the vaccine, which contains the antigen(s) of a pathogen, activates the immune system and provides protection against infection. The immunogenicity and allergenicity of a vaccine may lead to various adverse reactions, depending on the responsiveness and susceptibility of the vaccinated individual.

Hidradenitis suppurativa is a chronic inflammatory disease characterised by painful, deep-seated nodules, abscesses, and draining tunnels in the skin of axillary, inguinal, genitoanal, or inframammary areas. In recent years, the body of knowledge in hidradenitis suppurativa has advanced greatly. This disorder typically starts in the second or third decade of life.

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by pruritus and a relapsing course, affecting approximately 25% of children and 4-7% of adults. This study evaluated the efficacy, safety, and quality-of-life impact of tralokinumab, a humanized monoclonal antibody targeting interleukin-13 (IL-13), in treating moderate-to-severe AD in a real-world setting, with a focus on different AD phenotypes.
Methods: An observational cohort of 30 adults treated with tralokinumab for ≥ 16 weeks was analyzed.

The introduction of anti-tumor necrosis factor-α (anti-TNF-α) agents, particularly infliximab (IFX) and adalimumab (ADA), has significantly expanded the therapeutic arsenal for inflammatory bowel disease (IBD). While these biologics have demonstrated substantial efficacy, they are associated with a spectrum of potential adverse events (AEs). This study aims to evaluate and document these AEs to facilitate optimal patient selection and monitoring strategies of patients undergoing these therapies.
