TY - THES A1 - Horn, Johannes T1 - Behandlungsergebnisse und Vergleich der Harnableitungsverfahren von exenterativen Eingriffen bei nicht-urothelialen Malignomen T1 - Treatment results and comparison of urinary diversions post pelvic exenterations for non-urothelial cancers N2 - Die Zielsetzung dieser Studie ist, die operativen Daten, die Folgen, die Komplikationen, die Langzeit-Nierenfunktion und das Überleben der pelvinen Exenteration retrospektiv zu analysieren. Es wurde eine Gegenüberstellung der Behandlungsergebnisse von inkontinenten mit kontinenten Harnableitungen durchgeführt, um das aufwendigere Verfahren der kontinenten Form kritisch betrachten zu können. Im Zeitraum von 1992 bis 2013 wurden 64 Exenterationen in der Klinik und Poliklinik für Urologie und Kinderurologie der Universität Würzburg aufgrund nicht-urothelialer Malignome durchgeführt. Das mediane Alter des gesamten Patientenkollektivs lag bei 65 Jahren. Hierunter befanden sich 50 vordere und 14 komplette Exenterationen. Eine Harnableitung durch Anlage der inkontinenten Form erfolgte in 39 und durch Anlage der kontinenten Form in 25 Fällen. Das breite Spektrum der Malignomentitäten des gesamten Kollektivs umfasste nicht-urotheliale Malignome der Zervix, des Uterus, der Vulva, der Prostata, der Harnblase und des Darms. Bei 24 Patienten (37,5%) gelang keine R0-Resektion, und bei 18 Patienten (28,1%) konnte ein Lymphknotenbefall nachgewiesen werden. Die Frühkomplikationsrate betrug 58,8%. In einem Zeitraum von 365 Tagen nach Exenteration lag der mediane Clavien-Wert bei 2 Punkten. Die perioperative Sterblichkeit lag bei 0% und die Tumorprogressionsrate bei 48,4%. Die Analyse des Überlebens ergab eine mediane Gesamtüberlebenszeit von 30 Monaten und eine 5-Jahres-Gesamtüberlebensrate von 42,7% über das gesamte Kollektiv hinweg. Die tumorspezifische 5-JahresÜberlebensrate betrug 55,6%, und eine R0-Resektion erwies sich als hochsignifikante Einflussgröße bezüglich der tumorspezifischen Überlebenszeit. Ein signifikanter Einfluss des Lymphknotenbefalls konnte nicht nachgewiesen werden. Der Einfluss der Komorbidität erwies sich als noch geringer. Die beiden Kollektive der Harnableitungsformen unterschieden sich signifikant in Komorbiditätsgrad, OP-Dauer, Hospitalisierungszeit und bezüglich der Harnableitungskomplikationen. Die Unterschiede der Komorbidität und der OP-Dauer waren sogar hochsignifikant. Dabei wiesen die Patienten mit Anlage eines kontinenten Verfahrens eine niedrigere Komorbidität, eine längere OP-Dauer, eine längere Hospitalisierungszeit und prozentual mehr Komplikationen bezüglich der Harnableitung auf. Weitere wichtige Parameter, in denen sich die Kollektive geringfügig unterschieden, waren das Alter und die ASA-Klassifikation. Das Kollektiv mit Anlage einer kontinenten Form war jünger und zeigte einen kleineren Wert bezüglich der präoperativen Risikoeinschätzung. Diese Parameter unterschieden sich jedoch nicht signifikant voneinander. Die inkontinente Harnableitung zeigte einen etwas höheren Anteil an weiter fortgeschrittenen Tumorstadien, und nur in diesem Kollektiv lagen präoperativ Metastasen vor. Bei den Früh- und Spätkomplikationen konnte kein nennenswerter Unterschied zwischen den beiden Kollektiven nachgewiesen werden. Nur um wenige Prozentpunkte war die Frühkomplikationsrate der inkontinenten Form (61,3%) höher als die der kontinenten (55,0%). Um den Schweregrad der Komplikationen miteinzubeziehen, wurde der mediane Clavien-Wert aller Komplikationen innerhalb von 365 Tagen erfasst. Er betrug in beiden Kollektiven 2 Punkte. Bei der Analyse des Überlebens zeigte sich, dass das Kollektiv mit Anlage einer kontinenten Form eine knapp über dem Signifikanzlevel höhere Überlebenswahrscheinlichkeit sowohl bezüglich der gesamten als auch der progressionsfreien Überlebenszeit im Vergleich zu den inkontinenten Verfahren aufwies. Allerdings waren die Unterschiede nicht signifikant und beide Gruppen heterogen bezüglich des Alters, der Komorbidität, den Tumorstadien und den Malignomentitäten. Die vorliegende Studie kommt zu dem Ergebnis, dass R0-Resektionen bei exenterativen Eingriffen eine essentielle Voraussetzung für das langfristige tumorspezifische Überleben darstellen. In beiden Kollektiven der verschiedenen Harnableitungen zeigte sich kein bedeutsamer Unterschied bezüglich der Komplikationen. Die geringere OP-Dauer und die geringere Anzahl an Komplikationen mit der Harnableitung sprechen für das inkontinente Verfahren. Die Überlebensraten zeigten bessere Ergebnisse für die kontinente Form, jedoch waren die Unterschiede nicht signifikant. Dennoch ist eine Bevorzugung des kontinenten Verfahrens, wenn es technisch möglich und onkologisch vertretbar ist, nach intensiver Beratung und unter Berücksichtigung des Zustandes sowie der Wünsche des Patienten durchaus gerechtfertigt. Aufgrund des nichtrandomisierten retrospektiven Charakters dieser Studie, die 2 heterogene Kollektive vergleicht, sollten idealerweise prospektiv angelegte Studien mit größerer Patientenanzahl in der Zukunft klären, ob die hier gefundenen Ergebnisse generelle Gültigkeit haben. N2 - The objective of this study was to analyze the operative data, in order to determine the consequences, complications, renal function and survival rate of pelvic exenterations. The comparison of incontinent and continent urinary diversions took place to critically examine the complex procedure of the continent diversion. From 1992 to 2013, 64 exenterations were performed for non-urothelial cancers. The median age of the patients was 65 years. Incontinent urinary diversions were performed on 39 patients and continent urinary diversions on 25 patients. The wide range of different cancer types included non-urothelial cancers of the cervix, uterus, vulva, prostate, bladder and colon. The complication rate during the first 30 days was 58.8%. The median Clavien classification 365 days after the exenteration was 2 points, the perioperative mortality was 0%, and the tumor progression rate was 48.4%. Mortality revealed a median overall survival of 30 months and a 5-year overall survival rate of 42.7%. The cancer specific 5-year survival rate was 55.6% and R0 resection proved to be a significant influence on the cancer specific survival time. No significant influence of the lymph node status could be detected. No significant influence of comorbidities was detected either. The group of incontinent and continent urinary diversions differed significantly in comorbidities, operative time, hospital stay and complications stemming from the urinary diversion. The differences in comorbidity and operative time were highly significant. The patients with a continent urinary diversion showed lower comorbidity rates, longer operative time, longer hospital stay and more complications stemming from the urinary diversion. The mean age and the ASA classification were not significantly different. The patients with the continent urinary diversion were younger and showed a lower ASA classification. The patients, who received incontinent urinary diversions showed more advanced cancer stages. Metastases were only seen in the group receiving incontinent urinary diversion. No differences could be seen in early and late complications between the two groups. The complication rate within the first 30 days of the incontinent diversion group (61.3%) was only a few percentage points higher than that of the continent diversion group (55.0%). The Clavien classification of all complications were recorded to include the severity of the complications 365 days post procedure. Both groups showed 2 points. Analysis of mortality showed that the continent diversion group had a higher survival rate. In the overall and disease-free survival the difference was just above the significance level. This study concluded that R0 resections are an essential prerequisite for long-term cancer-specific survival in pelvic exenterations. Both the incontinent diversion group and continent diversion group showed no differences in complication rates. The incontinent urinary diversion group demonstrated a shorter operation time and fewer complications stemming from the urinary diversion. The continent urinary diversion group demonstrated a slightly better survival rate, but not a significant one. The continent urinary diversion procedure can be justified through intense review with the patient, if it is technically possible and acceptable from an oncological perspective. To determine if these results are generally valid, prospective studies with a larger number of patients should be done.

Here we investigated whether corticosteroid treatment can attenuate HIV disease progression in antiretroviral-untreated patients. Methods Double-blind, placebo-controlled randomized clinical trial including 326 HIV-patients in a resource-limited setting in Tanzania (clinicaltrials.gov NCT01299948). Inclusion criteria were a CD4 count above 300 cells/μl, the absence of AIDS-defining symptoms and an ART-naïve therapy status. Study participants received 5 mg prednisolone per day or placebo for 2 years. Primary endpoint was time to progression to an AIDS-defining condition or to a CD4-count below 200 cells/μl. Results No significant change in progression towards the primary endpoint was observed in the intent-to-treat (ITT) analysis (19 cases with prednisolone versus 28 cases with placebo, p = 0.1407). In a per-protocol (PP)-analysis, 13 versus 24 study participants progressed to the primary study endpoint (p = 0.0741). Secondary endpoints: Prednisolone-treatment decreased immune activation (sCD14, suPAR, CD38/HLA-DR/CD8+) and increased CD4-counts (+77.42 ± 5.70 cells/μl compared to -37.42 ± 10.77 cells/μl under placebo, p < 0.0001). Treatment with prednisolone was associated with a 3.2-fold increase in HIV viral load (p < 0.0001). In a post-hoc analysis stratifying for sex, females treated with prednisolone progressed significantly slower to the primary study endpoint than females treated with placebo (ITT-analysis: 11 versus 21 cases, p = 0.0567; PP-analysis: 5 versus 18 cases, p = 0.0051): No changes in disease progression were observed in men. Conclusions This study could not detect any significant effects of prednisolone on disease progression in antiretroviral-untreated HIV infection within the intent-to-treat population. However, significant effects were observed on CD4 counts, immune activation and HIV viral load. This study contributes to a better understanding of the role of immune activation in the pathogenesis of HIV infection.

A1 - Hain, Johannes A1 - Maponga, Tongai A1 - Riederer, Peter A1 - Koutsilieri, Eleni T1 - Increases in CSF dopamine in HIV patients are due to the dopamine transporter 10/10-repeat allele which is more frequent in HIV-infected individuals JF - Journal of Neural Transmission N2 - Dysfunction of dopaminergic neurotransmission has been implicated in HIV infection. We showed previously increased dopamine (DA) levels in CSF of therapy-naïve HIV patients and an inverse correlation between CSF DA and CD4 counts in the periphery, suggesting adverse effects of high levels of DA on HIV infection. In the current study including a total of 167 HIV-positive and negative donors from Germany and South Africa (SA), we investigated the mechanistic background for the increase of CSF DA in HIV individuals. Interestingly, we found that the DAT 10/10-repeat allele is present more frequently within HIV individuals than in uninfected subjects. Logistic regression analysis adjusted for gender and ethnicity showed an odds ratio for HIV infection in DAT 10/10 allele carriers of 3.93 (95 % CI 1.72–8.96; p = 0.001, Fishers exact test). 42.6 % HIV-infected patients harbored the DAT 10/10 allele compared to only 10.5 % uninfected DAT 10/10 carriers in SA (odds ratio 6.31), whereas 68.1 versus 40.9 %, respectively, in Germany (odds ratio 3.08). Subjects homozygous for the 10-repeat allele had higher amounts of CSF DA and reduced DAT mRNA expression but similar disease severity compared with those carrying other DAT genotypes. These intriguing and novel findings show the mutual interaction between DA and HIV, suggesting caution in the interpretation of CNS DA alterations in HIV infection solely as a secondary phenomenon to the virus and open the door for larger studies investigating consequences of the DAT functional polymorphism on HIV epidemiology and progression of disease.

The current study aimed to determine health-related quality of life (HRQoL) after COVID-19 hospitalization in non-intensive care unit (ICU) and ICU patients. This is a single-center study at the University Hospital of Wuerzburg, Germany. Patients eligible were hospitalized with COVID-19 between March 2020 and December 2020. Patients were interviewed 3 and 12 months after hospital discharge. Questionnaires included the European Quality of Life 5 Dimensions 5 Level (EQ-5D-5L), patient health questionnaire-9 (PHQ-9), the generalized anxiety disorder 7 scale (GAD-7), FACIT fatigue scale, perceived stress scale (PSS-10) and posttraumatic symptom scale 10 (PTSS-10). 85 patients were included in the study. The EQ5D-5L-Index significantly differed between non-ICU (0.78 ± 0.33 and 0.84 ± 0.23) and ICU (0.71 ± 0.27; 0.74 ± 0.2) patients after 3- and 12-months. Of non-ICU 87% and 80% of ICU survivors lived at home without support after 12 months. One-third of ICU and half of the non-ICU patients returned to work. A higher percentage of ICU patients was limited in their activities of daily living compared to non-ICU patients. Depression and fatigue were present in one fifth of the ICU patients. Stress levels remained high with only 24% of non-ICU and 3% of ICU patients (p = 0.0186) having low perceived stress. Posttraumatic symptoms were present in 5% of non-ICU and 10% of ICU patients. HRQoL is limited in COVID-19 ICU patients 3- and 12-months post COVID-19 hospitalization, with significantly less improvement at 12-months compared to non-ICU patients. Mental disorders were common highlighting the complexity of post-COVID-19 symptoms as well as the necessity to educate patients and primary care providers about monitoring mental well-being post COVID-19.
