Dermatologie (Heidelb)

July 2024

Klinik und Poliklinik für Dermatologie, Universität Düsseldorf, Düsseldorf, Deutschland.

Article Synopsis
  • Photosensitivity in lupus erythematosus leads to heightened inflammation from sunlight, affecting both skin (cutaneous lupus) and systemic health (systemic lupus).
  • UV radiation can trigger skin damage in cutaneous lupus, causing both temporary and permanent changes, while in systemic lupus, it may worsen the overall condition.
  • Understanding the mechanisms behind UV-induced immune responses is essential for creating strategies to prevent or mitigate the harmful effects of photosensitivity, as the only current prevention method is to avoid UV exposure.

  • Factitious disorder imposed on another (FDIA) is a type of child abuse where a caregiver fakes or causes illness in someone they care for, previously known as Munchausen syndrome by proxy.
  • A case study of a two-year-old girl showed symptoms resembling a serious autoimmune disease, but it turned out to be induced by her caregiver, who was secretly giving her a medication to simulate illness.
  • The girl did not improve despite medical treatment until the caregiver was separated, demonstrating the need for healthcare providers to consider FDIA when faced with unexplained or recurring health issues in children.

Rheumatoid arthritis (RA) is a complex autoimmune disease causing chronic joint inflammation and, in more serious cases, organ involvement. RA typically affects people between the ages of 35 and 60; however, it can also afflict children younger than the age of 16 years and can also demonstrate a pattern of remission later in the disease course. Non-steroidal anti-inflammatory drugs, glucocorticoids, exercise, and patient education are all used in the management of RA, which is divided into symptomatic management and disease-modifying management (disease-modifying antirheumatic drugs) to reduce pain and inflammation, thereby preserving joint function.

Background: The increasing prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) incurs substantial morbidity, mortality and healthcare costs. Detection and clinical intervention at early stages of disease improves prognosis; however, we are currently limited by a lack of reliable diagnostic tests for population screening and monitoring responses to therapy. To address this unmet need, we investigated human invariant Natural Killer T cell (iNKT) activation by fat-loaded hepatocytes, leading to the discovery that circulating soluble CD46 (sCD46) levels accurately predict hepatic steatosis.

TSPO ligands are promising alternatives to benzodiazepines in the treatment of anxiety, as they display less pronounced side effects such as sedation, cognitive impairment, tolerance development and abuse potential. In a randomized double-blind repeated-measures study we compare a benzodiazepine (alprazolam) to a TSPO ligand (etifoxine) by assessing side effects and acquiring resting-state fMRI data from 34 healthy participants after 5 days of taking alprazolam, etifoxine or a placebo. To study the effects of the pharmacological interventions in fMRI in detail and across different scales, we combine in our study complementary analysis strategies related to whole-brain functional network connectivity, local connectivity analysis expressed in regional homogeneity, fluctuations in low-frequency BOLD amplitudes and coherency of independent resting-state networks.

Cryopreservation of spheroids requires development of new improved methods. The plasma membranes permeability coefficients for water and cryoprotectants determine time characteristics of mass transfer through the cell membranes, and therefore the optimal modes of cells cryopreservation. Here we proposed an approach to cryopreservation of multicellular spheroids which considers their generalized characteristics as analogues of the membranes' permeability coefficients of the individual cells.
