  abstract  = {Sarcoidosis is a multisystem granulomatous disorder of unknown etiology that can involve virtually all organ systems. Whereas most patients present without symptoms, progressive and disabling organ failure can occur in up to 10\% of subjects. Somatostatin receptor (SSTR)-directed peptide receptor radionuclide therapy (PRRT) has recently received market authorization for treatment of SSTR-positive neuroendocrine tumors. Methods: We describe the first case series comprising two patients with refractory multi-organ involvement of sarcoidosis who received 4 cycles of PRRT. Results: PRRT was well-tolerated without any acute adverse effects. No relevant toxicities could be recorded during follow-up. Therapy resulted in partial response accompanied by a pronounced reduction in pain (patient \#1) and stable disease regarding morphology as well as disease activity (patient \#2), respectively. Conclusion: Peptide receptor radionuclide therapy in sarcoidosis is feasible and might be a new valuable tool in patients with otherwise treatment-refractory disease. Given the long experience with and good tolerability of PRRT, further evaluation of this new treatment option for otherwise treatment-refractory sarcoidosis in larger patient cohorts is warranted.},

  abstract  = {Diagnosis of cardiac sarcoidosis is often challenging. Whereas cardiac magnetic resonance imaging (CMR) and positron emission tomography/computed tomography (PET/CT) with \(^{18}\)F-fluorodeoxyglucose (FDG) are most commonly used to evaluate patients, PET/CT using radiolabeled somatostatin receptor (SSTR) ligands for visualization of inflammation might represent a more specific alternative. This study aimed to investigate the feasibility of SSTR-PET/CT for detecting cardiac sarcoidosis in comparison to CMR. 15 patients (6 males, 9 females) with sarcoidosis and suspicion on cardiac involvement underwent SSTR-PET/CT imaging and CMR. Images were visually scored. The AHA 17-segment model of the left myocardium was used for localization and comparison of inflamed myocardium for both imaging modalities. In semi-quantitative analysis, mean (SUV\(_{mean}\)) and maximum standardized uptake values (SUV\(_{max}\)) of affected myocardium were calculated and compared with both remote myocardium and left ventricular (LV) cavity. SSTR-PET was positive in 7/15, CMR in 10/15 patients. Of the 3 CMR+/PET- subjects, one patient with minor involvement (<25\% of wall thickness in CMR) was missed by PET. The remaining two CMR+/PET- patients displayed no adverse cardiac events during follow-up. In the 17-segment model, PET/CT yielded 27 and CMR 29 positive segments. Overall concordance of the 2 modalities was 96.1\% (245/255 segments analyzed). SUV\(_{mean}\) and SUV\(_{max}\) in inflamed areas were 2.0±1.2 and 2.6±1.2, respectively. The lesion-to-remote myocardium and lesion-to-LV cavity ratios were 1.8±0.2 and 1.9±0.2 for SUV\(_{mean}\) and 2.0±0.3 and 1.7±0.3 for SUV\(_{max}\), respectively. Detection of cardiac sarcoidosis by SSTR-PET/CT is feasible. Our data warrant further analysis in larger prospective series.},

  abstract  = {In dieser Arbeit wurde die Bedeutung von Zytokinen und das Auftreten einer epithelialen Schrankenstoerung bei interstitiellen Lungenkrankheiten untersucht und diskutiert. Dazu wurden von 105 Patienten Bronchoskopien sowie laborchemische und klinische Daten ausgewertet. Schwerpunkt der Untersuchungen bezogen sich auf IL-2 Rezeptor, IL-8 und Lysozym in bronchoalveolaerer Lavagefluessigkeit (BALF) und Serum bei Patienten mit Sarkoidose, Exogen-allergischer Alveolitis (EAA) und interstitieller Lungenfibrose (IPF). Unbehandelte Sarkoidosepatienten hatten {\"u}ber den Normbereich erhoehte IL-2 Rez. Werte im Serum, in der BALF konnte der IL-2 Rez. regelmaessig nachgewiesen werden, ein Normbereich ist in der Literatur nicht definiert. Die IL-8 Werte bei Sarkoidose waren erhoeht messbar, jedoch im Gruppenvergleich auf unterem Nivau. Patienten mit EAA hatten signifikant erhoehte IL-8 Werte im Serum und in der BALF. Im Gruppenvergleich fanden sich hier die hoechsten Werte. Der IL-2 Rez. war bei EAA in der BAL auf hohem Niveau nachzuweisen. Die hoechsten IL-2 Rez. Werte der BALF zeigte die Gruppe der IPF, die Serumwerte lagen im oberen Normbereich. IL-8 Werte der BALF waren bei IPF erhoeht. Eine epitheliale Schrankenstoerung, beurteilt durch den Albuminquotienten zwischen Lavage- und Serumalbumin, zeigte sich bei allen Diagnosegruppen. Die am staerksten ausgepraegte Epithelfunktionsstoerung war bei Sarkoidosepatienten zu sehen. Die Ergebnisse wurden mit der aktuellen Literatur verglichen und diskutiert.},
