Late recovery with cyclosporine-A of an auto-immune sudden sensorineural hearing loss

Sensorineural hearing loss of immune-mediated origin may be present as a symptom in systemic autoimmune diseases or may occur as a primary disorder without other organ involvement (auto-immune inner ear disease). The diagnosis of auto-immune inner ear disease is still predicated on clinical features and to date specific diagnostic tests are not available. We report a case of right-sided sudden hearing loss in a female patient in which the clinical manifestations, in addition to ANA positivity and hypocomplementaemia allowed us to hypothesize an auto-immune inner ear disease. The immunosuppressive treatment with cyclosporine-A was capable of a recovery of the hearing that, however, occurred progressively with normalization of the hearing function after 1 year of treatment. cyclosporine-A could be proposed as a therapeutic option in case of auto-immune inner ear disease allowing the suspension of corticosteroids that, at high dose, expose patients to potentially serious adverse events

Once daily levocetirizine for the treatment of allergic rhinitis and chronic idiopathic urticaria

Levocetirizine is the pharmacologically active enantiomer of cetirizine. It is a potent histamine H-1 receptor antagonist with anti-inflammatory and antiallergic properties. The review analyses the levocetirizine’s properties in terms of safety and efficacy both in allergic rhinitis and urticarioid syndromes

Acquired angioedema with C1 inhibitor deficiency associated with anticardiolipin antibodies.

Acquired angioedema (AAE) with C1 inhibitor deficiency is often associated to B cell lymphoproliferative disorders or autoimmune diseases. We report a case of AAE associated with IgM anti-cardiolipin antibodies, with frequent edematous attacks, that disappeared completely after a slight immunosuppression and danazol therapy

Safety of measles, mumps, and rubella vaccine in egg allergy: in vivo and in vitro management

Background: Egg allergy is the second most prevalent form of food allergy in childhood. In spite of the evidence accumulated, inoculating egg allergy children with attenuated vaccines grown on chick embryo cell cultures, such as the measles, mumps, and rubella (MMR) vaccine, is regarded (erroneously) as potentially dangerous or even anaphylactogenic, by many. An issue perceived as particularly conflicting also by Health Professionals. Case presentation: A 15-year-old boy, with a history of severe egg allergy in early infancy, who was still sensitized to egg allergens, including baked egg, had never received MMR vaccination, in fear of possible anaphylaxis, in spite of the fact that this vaccination is mandatory in the first year of life, in Italy. Because of that, he was not allowed to attend school, longer, and was referred to us in order to assess the potential risk of MMR vaccination. Upon thorough allergologic workup, sensitization to MMR vaccine components was excluded by an in vivo approach, consisting in skin prick tests, intradermal tests, and subcutaneous injection test, corroborated by vaccine-specific B-lymphocyte proliferation assay, ex vivo. T-cell proliferation in response to MMR vaccine was also excluded. Eventually, the boy was inoculated with MMR vaccine and was readmitted to school. Conclusions: The diagnostic strategy adopted appears feasible and easy-to-perform and may be adopted in controversial cases (as the one reported), characterized by previous severe allergic reactions to egg. The B-lymphocyte proliferation assay we developed may represent a useful and reliable tool not only in research but also in clinical practice

Efficacy of dupilumab in atopic comorbidities associated with moderate-to-severe adult atopic dermatitis

Background: Dupilumab is an anti-IL-4Rα antibody used in the treatment of patients with moderate-to-severe atopic dermatitis (msAD). This study explored the potential benefit of dupilumab in perennial allergic rhinoconjunctivitis (PAR) and perennial allergic asthma (PAA) caused by indoor allergens in adults with msAD. Methods: This multicentric, prospective, observational, real-life study included adult patients with msAD who had been treated with dupilumab in 16 Italian care centres. Efficacy outcomes regarding AD, PAR and PAA were collected at baseline and 16 weeks. Safety was also assessed. Results: We enrolled 123 patients with msAD. Between baseline and 16 weeks of treatment, the following measurements decreased statistically significantly: Eczema Area and Severity Index, SCOring AD, Patient-Oriented Eczema Measure, pruritus score, sleep score, Dermatology Life Quality Index and IgE. Dupilumab treatment in patients with comorbid PAR (n = 41) was associated with significant improvements in PAR disease control (measured using a Rhinitis Control Scoring System) and in PAR Quality of life (QoL) (measured using the Rhinoconjunctivitis QoL Questionnaire scores). In 32 patients with comorbid PAA, dupilumab significantly improved PAA control (measured using the Asthma Control Test and five-item Asthma Control Questionnaire scores) and disease-related QoL (measured using the Asthma QoL Questionnaire scores). Thirty-five patients (28.5%) developed conjunctivitis during the study period. Conclusion: These results support the benefits of dupilumab for adult patients with PAR and/or PAA associated with msAD

Choroid plexus enlargement is associated with neuroinflammation and reduction of blood brain barrier permeability in depression.

BACKGROUND: Recent studies have shown that choroid plexuses (CP) may be involved in the neuro-immune axes, playing a role in the interaction between the central and peripheral inflammation. Here we aimed to investigate CP volume alterations in depression and their associations with inflammation. METHODS: 51 depressed participants (HDRS score > 13) and 25 age- and sex-matched healthy controls (HCs) from the Wellcome Trust NIMA consortium were re-analysed for the study. All the participants underwent full peripheral cytokine profiling and simultaneous [11C]PK11195 PET/structural MRI imaging for measuring neuroinflammation and CP volume respectively. RESULTS: We found a significantly greater CP volume in depressed subjects compared to HCs (t(76) = +2.17) that was positively correlated with [11C]PK11195 PET binding in the anterior cingulate cortex (r = 0.28, p = 0.02), prefrontal cortex (r = 0.24, p = 0.04), and insular cortex (r = 0.24, p = 0.04), but not with the peripheral inflammatory markers: CRP levels (r = 0.07, p = 0.53), IL-6 (r = -0.08, p = 0.61), and TNF-α (r = -0.06, p = 0.70). The CP volume correlated with the [11C]PK11195 PET binding in CP (r = 0.34, p = 0.005). Integration of transcriptomic data from the Allen Human Brain Atlas with the brain map depicting the correlations between CP volume and PET imaging found significant gene enrichment for several pathways involved in neuroinflammatory response. CONCLUSION: This result supports the hypothesis that changes in brain barriers may cause reduction in solute exchanges between blood and CSF, disturbing the brain homeostasis and ultimately contributing to inflammation in depression. Given that CP anomalies have been recently detected in other brain disorders, these results may not be specific to depression and might extend to other conditions with a peripheral inflammatory component

Drug induced exfoliative dermatitis: State of the art

Drug induced exfoliative dermatitis (ED) are a group of rare and severe drug hypersensitivity reactions (DHR) involving skin and usually occurring from days to several weeks after drug exposure. Erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are the main clinical presentations of drug induced ED. Overall, T cells are the central player of these immune-mediated drug reactions. Here we provide a systematic review on frequency, risk factors, pathogenesis, clinical features and management of patients with drug induced ED
