IL-17-producing cells are present in lesional and perilesional HS skin and may contribute to the initiation of inflammatory processes. Furthermore, the epidermis is a source of proinflammatory cytokines, shows inflammasome activation and expresses S100A8/S100A9, thereby possibly contributing to the propagation of inflammation. A massive influx of IL-17-expressing neutrophils is observed in the deep infiltrate.
Background: Fingolimod is used for immune therapy in patients with multiple sclerosis. Long-term treatment is associated with a small increase in the risk of herpes virus reactivation and respiratory tract infections. Patients with coronavirus disease 2019 (COVID-19) under Fingolimod treatment have not been described. Methods and results: We report a 57-year old female patient with a relapsing remitting multiple sclerosis under fingolimod treatment who experienced a severe COVID-19 infection in March 2020 (Extended Disability Status Scale: 2.0). Having peripheral lymphopenia typical for fingolimod treatment (total lymphocytes 0.39/nL [reference range 1.22-3.56]), the patient developed bilateral interstitial pneumonia with multiple ground-glass opacities on chest CT. Fingolimod medication was stopped. On the intensive care unit, non-invasive ventilation was used to provide oxygen and ventilation support regularly. Over the following two days, oxygenation improved, and the patient was transferred to a normal ward five days after admission.
Conclusion:The implications fingolimod has on COVID-19 are complex. As an S1P analogue, fingolimod might enhance lung endothelial cell integrity. In addition, in case of a so-called cytokine storm, immunomodulation might be beneficial to reduce mortality. Future studies are needed to explore the risks and therapeutic effects of fingolimod in COVID-19 patients.
Advantages of the scalp as a donor site include rapidity of wound healing, low risk of complications, and excellent cosmetic results. The large number of hair follicles containing the epidermal stem cell pool can explain these advantages.
Patients with psoriasis have an increased risk of cardiovascular disease that is partly attributable to chronic systemic inflammation. The aim of our prospective pilot study was to investigate the impact of fumaric acid esters (FAE), a first-line systemic antipsoriatic treatment in Germany, on cardiovascular risk parameters. Participants with moderate-to-severe psoriasis from the University Medical Center Mannheim and the University Hospital Würzburg were treated with FAE for 16 weeks according to standard dosage recommendations. Disease severity, life quality and depression scores as well as biomarkers of inflammation, lipid and glucose metabolism were assessed prior to initiation of FAE and after 16 weeks. Out of 39 participants recruited, 27 completed the study. 44% of all participants and 63% of those completing the 16-week treatment achieved PASI 50 response and 27 or 37% PASI 75 response. Clinical improvement was paralleled by significant improvement in quality of life, high treatment satisfaction and significant reduction of depressive symptoms. Adverse events, most frequently mild gastrointestinal complaints, flush and lymphocytopenia occurred in 89%. FAE did not modify glucose metabolism or inflammatory parameters substantially. However, a highly significant increase in serum levels of the atheroprotective cytokine adiponectin was noted after 16 weeks (median 4.7 vs. 8.9 µg/ml; p = 0.0002). Our study demonstrates a significant beneficial impact of FAE on adiponectin, indicating a potential cardioprotective effect. It will be interesting to verify this finding in larger cohorts and to assess the long-term influence of FAE on cardiovascular risk and disease.
Brooke-Spiegler syndrome is an autosomal dominant tumor predisposition disorder. The disease is characterized by the occurrence of multiple skin appendage tumors, including cylindroma, trichoepithelioma, and spiradenoma. In some patients, tumors cover the entire head circumference, thereby causing disfigurement and other complications. Here, we report on a man with multiple cylindroma that were distributed in a turban tumor-like fashion. One of these neoplasms arose in the meatus externus of the right ear leading to unilateral hearing loss, a complication that has been documented only on few occasions in this disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
