Background and objectives
Bullous pemphigoid (BP) is associated with neuropsychiatric disorders. Other comorbid diseases are discussed controversially. We evaluated the prevalence of comorbidity in BP patients in a representative area of Germany.
Patients and methods
Medical files of all BP patients treated at the Department of Dermatology, University Hospital Würzburg, Germany, between June 2002 and May 2013 were retrospectively reviewed. Bullous pemphigoid was diagnosed based on established criteria. For each patient, two controls were individually matched. Records were evaluated for age, sex, laboratory values, concomitant medication and comorbidity. Conditional logistic regression, multivariable regression analysis and complex regression models were performed to compare results.
Results
300 BP patients were identified and compared to 583 controls. Bullous pemphigoid was associated with neuropsychiatric disorders as well as laboratory abnormalities including leukocytosis and eosinophilia. Importantly, a highly significant association of BP with anemia (OR 2.127; 95 % CI 1.532–2.953) and renal impairment (OR 2.218; 95 % CI 1.643–2.993) was identified. No association was found with malignancy and arterial hypertension.
Conclusions
Our data revealed an increased frequency of anemia and renal impairment in BP patients. In accordance with previous studies the strong association for neuropsychiatric disorders was confirmed (p < 0.0005).
Das Bullöse Pemphigoid (BP) ist eine blasenbildende Autoimmunerkrankung der Haut, die durch subepidermale Blasenbildung und Antikörper (AK) gegen bestimmte hemidesmosomale Proteine der Basalmembran (BM) charakterisiert ist. Zielantigene sind BP180 und BP230. Im Fokus dieser Arbeit stand die retrospektive Identifikation und Datenerhebung von Patienten mit BP, die in der Dermatologie der Uniklinik Würzburg behandelt wurden. Zudem wurde eine Kontrollgruppe aus Patienten mit Basalzellkarzinom etabliert. Es konnten (hoch-)signifikante Assoziationen zwischen dem BP und verschiedenen Laborparametern (u.a. Leukozytose, Eosinophilie, Thrombozytose, Anämie, Kreatinin erhöht) sowie Erkrankungen (u.a. neurologische Erkrankungen (Schlaganfall, Demenz, MP, MS und Epilepsie) sowie psychiatrischen Erkrankungen (HOPS, Depression) und Diabetes mellitus) nachgewiesen werden.
Systemic treatment of metastatic uveal melanoma: review of literature and future perspectives
(2013)
Up to 50% of patients with uveal melanoma develop metastatic disease with poor prognosis. Regional, mainly liver-directed, therapies may induce limited tumor responses but do not improve overall survival. Response rates of metastatic uveal melanoma (MUM) to systemic chemotherapy are poor. Insights into the molecular biology of MUM recently led to investigation of new drugs. In this study, to compare response rates of systemic treatment for MUM we searched Pubmed/Web of Knowledge databases and ASCO website (1980–2013) for “metastatic/uveal/melanoma” and “melanoma/eye.” Forty studies (one case series, three phase I, five pilot, 22 nonrandomized, and two randomized phase II, one randomized phase III study, data of three expanded access programs, three retrospective studies) with 841 evaluable patients were included in the numeric outcome analysis. Complete or partial remissions were observed in 39/841 patients (overall response rate [ORR] 4.6%; 95% confidence intervals [CI] 3.3–6.3%), no responses were observed in 22/40 studies. Progression-free survival ranged from 1.8 to 7.2, median overall survival from 5.2 to 19.0 months as reported in 21/40 and 26/40 studies, respectively. Best responses were seen for chemoimmunotherapy (ORR 10.3%; 95% CI 4.8–18.7%) though mainly in first-line patients. Immunotherapy with ipilimumab, antiangiogenetic approaches, and kinase inhibitors have not yet proven to be superior to chemotherapy. MEK inhibitors are currently investigated in a phase II trial with promising preliminary data. Despite new insights into genetic and molecular background of MUM, satisfying systemic treatment approaches are currently lacking. Study results of innovative treatment strategies are urgently awaited.
