Psoriasis is an inflammatory, immune-mediated disease that is frequently associated with psychological comorbidities such as depression. The stigma patients feel because of the appearance of their skin may contribute to the high psycho-social burden of psoriasis. However, there is emerging evidence that overlapping biological mechanisms are, to a substantial degree, responsible for the close interaction between psoriasis and depression. Increased proinflammatory mediators, such as C-reactive protein or interleukin-6, are present in both psoriasis and depression, indicating that inflammation may represent a pathophysiological link between the diseases. Anti-inflammatory biologic therapies treat the clinical manifestations of psoriasis, but might also play a significant role in reducing associated depressive symptoms in patients with psoriasis. Comparison between single studies focusing on the change in depressive symptoms in psoriasis is limited by inconsistency in the depression screening tools applied.
Background: Anti-PD1 monoclonal antibody nivolumab is an approved therapy option for the treatment of advanced squamous cell non-small cell lung cancer (SQ-NSCLC) patients. Data outside clinical trials about therapy efficacy and safety in later therapy line treatments have rarely been described until now. Methods: We performed a retrospective data analysis of patients who were enrolled into the nivolumab Compassionate Use Program (CUP) in Germany. Sufficient clinical data of 40 patients were available for efficacy and safety analysis. Results: Overall, 47.5% of all treated patients were not affected by any adverse events (AEs); 17.5% of patients suffered from severe AEs. The 1-year survival rate was 61.3%. Estimated median progression-free survival (PFS) was 5.3 months. Patients who received nivolumab as third or later therapy line treatment (77.5%) achieved similar median PFS and 12-month overall survival rate of 52%. Conclusion: Our findings of immunotherapy treatment outside clinical trials support the results of studies in the past and confirm the efficacy and favorable toxicity profile of nivolumab treatment in advanced SQ-NSCLC patients. In addition, we can present some rarely described information about nivolumab treatment of heavily pretreated patients, which provides some evidence that immunotherapy could also be useful in later therapy lines.
Zusammenfassung Hintergrund Patientenerwartungen in Bezug auf den Nutzen einer medizinischen Behandlung stellen eine wichtige Determinante für die Placeboantwort dar. Sie können Entwicklung und Verlauf von Erkrankungen sowie Wirksamkeit und Verträglichkeit von Therapien maßgeblich beeinflussen. Die Mechanismen, die diese Placebo- und Noceboeffekte vermitteln, wurden bislang am besten auf dem Gebiet der Placeboanalgesie beschrieben. Aber auch in der Dermatologie findet sich eine zunehmende Evidenz dafür, dass verschiedene Symptome wie Schmerzen an der Haut und Pruritus (Jucken) sowie verschiedene dermatologische Erkrankungen durch die Behandlungserwartungen von Patienten moduliert werden können. Ziel der Arbeit Das Ziel dieser Arbeit ist die Darstellung der aktuellen Datenlage in Bezug auf den Einfluss von Erwartungseffekten auf dermatologische Symptome wie Pruritus und Hautschmerzen sowie auf verschiedene dermatologische Erkrankungen. Schließlich soll die Bedeutung dieses Themas für Ärzte, die Patienten mit Hautsymptomen behandeln, vermittelt werden. Material und Methoden Es handelt sich um eine narrative Übersichtsarbeit. Ergebnisse und Diskussion Eine zunehmende Anzahl von Studien an gesunden Probanden und dermatologischen Patienten zeigt, dass Hautsymptome wie Pruritus und Schmerzen durch die Induktion positiver Erwartungen verringert und durch die Induktion negativer Erwartungen verstärkt werden können. Vorherige Behandlungserfahrungen der Patienten sowie die Qualität und Quantität der Arzt-Patienten-Kommunikation spielen für die Induktion der Behandlungserwartung eine zentrale Rolle. Schlussfolgerung Techniken, die darauf abzielen, positive Erwartungseffekte von Patienten mit Hautsymptomen zu maximieren und negative zu minimieren, sollten in die klinische Routine implementiert werden.
Introduction: Fixed-dose pembrolizumab (200 mg abs., d1, q3w) for the treatment of malignant pleural mesothelioma did not result in survival benefit in the phase 3 PROMISE-meso trial compared to 2 ndline chemotherapy. Due to lack of validated imaging response criteria, respondersubgroups with potential survival benefit have not yet been identified. Here, we administered highdose pembrolizumab (10 mg/kg, d1, q2w) considering the KEYNOTE-028 trial and assessed the prognostic value of PET metabolic response in patients with chemotherapy-resistant malignant mesothelioma of the pleura or peritoneum.Methods: Data from 27 patients with baseline and follow-up 18 F-FDG PET/CT imaging were retrospectively analyzed. RECIST v1.1, mRECIST, PERCISTSULpeak and PERCISTMTV were used separately to categorize responders in CT and PET imaging studies. Progression-free survival (PFS) and overall survival (OS) of responders were compared to non-responders using Kaplan-Meier and log-rank analyses. Programmed Cell Death Protein 1 (PD-L1) expression status was assessed and its association with outcome was investigated.Results: 27 patients had 18 F-FDG-PET/CT imaging at baseline and after at least 4 cycles pembrolizumab. Median PFS and OS were 3.4 and 15.1 months, respectively. Response rates were 7%, 7%, 30%, and 30% based on RECIST v1.1, mRECIST, PERCISTSULpeak, and PERCISTMTV response criteria, respectively. Response according to PERCISTMTV predicted prolonged OS or PFS (p < 0.01), whereas all other imaging criteria and PD-L1 expression did not. Conclusion: 18 F-FDG PET metabolic volume response predicts survival in patients with malignant mesothelioma receiving high-dose pembrolizumab. These results should prompt inclusion of PET response assessment in future phase 3 clinical trials.
