Abstract

Background

Immunologic therapies for melanoma rarely succeed, suggesting a persistent counter-regulatory immune modulation. Regulatory T cells (Tregs) and plasmacytoid subpopulations of dendritic cells (pDCs) inhibit the immune response. We hypothesize that melanoma upregulates Tregs and subpopulations of immunosuppressive dendritic cells (DCs).

Methods

Peripheral blood mononuclear cells (PBMCs) were obtained from healthy controls, stage I and stage IV melanoma patients. Tregs were identified as CD4+ and CD25hi. Dendritic cells were identified using a DC cocktail of antibodies including CD11c+ myeloid dendritic cells (mDCs) and CD123+ pDCs. Serum transforming growth factor-β (TGF-β), interleukin-4 (IL-4) and interleukin-10 (IL-10) levels were determined by enzyme-linked immunosorbent assay (ELISA). Statistical analysis was performed using analysis of variance (ANOVA).

Results

Stage IV melanoma patients had a doubling of regulatory T cells compared to both normal subjects and stage I melanoma patients. There was a significantly higher number of DCs in all melanoma patients compared to normal subjects. Stage I melanoma patients had a significantly higher number of pDCs than normal subjects, and all melanoma patients had a higher concentration of mDCs than controls. Serum IL-4 and IL-10 were not detectable but serum TGF-β levels were significantly higher in stage I and stage IV melanoma patients compared to normal controls.

Conclusion

Advanced melanoma is associated with increased numbers of circulating dendritic cells and regulatory T cells. These data suggest that melanoma induces immunosuppressive DCs and regulatory T cells in the systemic circulation.

In der Notaufnahme wird die Chance, Opfer von häuslicher Gewalt zu identifizieren, von Orthopäden und Orthopädinnen offenbar zu wenig genutzt. Darauf deuten die Ergebnisse einer Fragebogenstudie an der Sahlgrenska-Universität in Schweden hin.

Darüber reden und aus Fehlern lernen, sollte das Motto in der Medizin lauten. Und zwar nicht nur im Sinne der Patientensicherheit. Eine negative Fehlerkultur kann auch die Behandelnden ernsthaft krank machen, warnt Prof. Dr. Reinhard Strametz. Ein Plädoyer und ein Leitfaden für den offenen Umgang mit kritischen Ereignissen in Medizin und Pflege.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
