Happiness Behind the Scenes: Associations between Heuristic Happiness and Related Dimensions in Skin Diseases.

Positive health approaches, such as happiness, are largely unexplored in medicine, including dermatology. Taking into consideration the various happiness measures, the aims of this cross-sectional study were to assess this concept using a 1-item heuristic happiness question and its related dimensions (Satisfaction with Life, Positive and Negative Affect, Quality of Life, and Compound Psychological Capital) in outpatients with different skin diseases between December 2019 and June 2020, and to examine the link between these dimensions. Overall, 414 dermatological patients were included: 67 with psoriasis, 84 atopic eczema, 10 mastocytosis, 19 nummular eczema, 84 malignant melanoma and 150 keratinocyte carcinoma. Comparing the skin diseases, differences were observed for heuristic happiness, Positive Affect, and some domains of Quality of Life and Compound Psychological Capital. Analysing the relationship between heuristic happiness and other happiness measures, the data revealed moderate to strong correlations (r = 0.30-0.46, p< 0.001) and variations in the understanding of happiness between the skin diseases. Overall, the most important facet of happiness was Hope as a domain of Compound Psychological Capital. This study emphasizes the individual definition of heuristic happiness in patients with skin diseases. A 1-item heuristic approach may be a simple and practical method to assess the complexity and individuality of happiness.

Kinase inhibitors increase individual radiation sensitivity in normal cells of cancer patients.

PURPOSE: Kinase inhibitors (KI) are known to increase radiosensitivity, which can lead to increased risk of side effects. Data about interactions of commonly used KI with ionizing radiation on healthy tissue are rare. PATIENTS AND METHODS: Freshly drawn blood samples were analyzed using three-color FISH (fluorescence in situ hybridization) to measure individual radiosensitivity via chromosomal aberrations after irradiation (2 Gy). Thresholds of 0.5 and 0.6 breaks/metaphase (B/M) indicate moderate or clearly increased radiosensitivity. RESULTS: The cohorts consisted of healthy individuals (NEG, n = 219), radiosensitive patients (POS, n = 24), cancer patients (n = 452) and cancer patients during KI therapy (n = 49). In healthy individuals radiosensitivity (≥ 0.6 B/M) was clearly increased in 5% of all cases, while in the radiosensitive cohort 79% were elevated. KI therapy increased the rate of sensitive patients (≥ 0.6 B/M) to 35% significantly compared to 19% in cancer patients without KI (p = 0.014). Increased radiosensitivity of peripheral blood mononuclear cells (PBMCs) among patients occurred in six of seven KI subgroups. The mean B/M values significantly increased during KI therapy (0.47 ± 0.20 B/M without compared to 0.50 ± 0.19 B/M with KI, p = 0.047). CONCLUSIONS: Kinase inhibitors can intensify individual radiosensitivity of PBMCs distinctly in 85% of tested drugs.

Happiness and depression in psoriasis: a cross-sectional study in Germany.

PURPOSE: Prior research on the psychological consequences of skin diseases has focused on assessing mental comorbidities. The aim of this study was to investigate subjective well-being in a large sample of individuals affected by psoriasis, a chronic inflammatory skin disease, and to explore the associations with depression and disease-related parameters such as disease severity. METHODS: A cross-sectional online survey was conducted from March to June 2019. The link to the questionnaire was shared on websites and Facebook pages of psoriasis patient organizations and campaigns. Participants filled in validated scales measuring subjective well-being-operationalized as positive affect (PA), negative affect (NA) and satisfaction with life (SWL); and depression. RESULTS: The data of 722 participants were analyzed. Exploratory factor analysis supported the differentiation of PA, NA, SWL, and depression as four different constructs. The respondents reported lower levels of PA than healthy individuals and judged themselves to be less happy and were less satisfied with their lives than the general population (except age group 65 + years). 40.3% of respondents were screened positive for depression. More severe psoriasis was associated with lower affective well-being and a higher risk for depression. CONCLUSION: The results of this study empirically supported the differentiation of subjective well-being and depression as different constructs in individuals with psoriasis, and underline the large mental burden of the disease which goes beyond a higher risk for depression. Measures of well-being should thus be incorporated in both research and clinical practice in patients with psoriasis in order to achieve a more comprehensive picture of the mental burden of this disease.

Kenntnisse bayerischer Schüler zu sexuell übertragbaren Infektionen: eine Querschnittsstudie.

HINTERGRUND UND ZIELE: Trotz zahlreicher Informationsquellen und Kampagnen zu sexuell übertragbaren Infektionen (STI) haben diese Krankheiten in Deutschland in den letzten Jahren zugenommen. Ziel war es, das Bewusstsein und den Wissensstand junger Schüler in Bayern zu sexuell übertragbaren Krankheiten (STI) mit Schwerpunkt auf humane Papillomaviren (HPV) zu bewerten. METHODEN: In einer vollständig irreversibel anonymisierten Querschnittsstudie wurden insgesamt 4100 bayerische Schüler im Alter zwischen 12 und 17 Jahren anhand eines Multiple-Choice-Fragebogens hierzu befragt. ERGEBNISSE: Insgesamt wurden 3834 Fragebögen in die Datenanalyse einbezogen. Interessanterweise ist der Bekanntheitsgrad von HPV im Vergleich zu anderen STI bemerkenswert geringer. Mädchen und Jugendliche, die bereits vorbeugende Jugendgesundheitsuntersuchungen absolviert hatten, zeigten im Durchschnitt ein größeres Wissen über STI. Darüber hinaus konnten wir zeigen, dass Jugendliche mit geringerem Bildungsniveau, wie Realschüler, über die geringsten Kenntnisse verfügten. SCHLUSSFOLGERUNGEN: Die Querschnittsstudie zeigt, dass viele junge Menschen noch unzureichend über STI informiert sind. Die Informationslücken unterstreichen die Notwendigkeit einer intensiven und langfristigen Aufklärungsarbeit.

Evaluation of the knowledge of students concerning sexually transmitted infections in Bavaria/Germany (a cross-sectional study).

BACKGROUND AND OBJECTIVES: Despite numerous information sources and campaigns on sexually transmitted infections (STIs), there has been an increase in STIs in Germany in recent years. The aim was to evaluate the awareness and knowledge level among young students in Bavaria/Germany for STIs with a focus on human papilloma viruses (HPV). METHODS: In a cross-sectional survey rendered completely and irreversibly anonymous, a total of 4,100 students from Bavaria between the ages of 12 and 17 were interviewed using a multiple choice questionnaire about their knowledge and awareness of STI, on the basis of gender, school education and preventive youth health examinations that had taken place. RESULTS: A total of 3,834 questionnaires were included in the data analysis. Interestingly, the awareness level for HPV is remarkably lower compared to other STIs. Girls and adolescents who had already taken preventive youth health examinations showed a higher knowledge of STIs on average. Additionally, we could show that adolescents of lower educational levels, such as secondary school students, had the least knowledge. CONCLUSIONS: The cross-sectional study shows that many young people are still insufficiently informed about STIs. The gaps in information and lack of knowledge underline the necessity of intensive and long-term educational work.

Molecular diagnostics in dermatology: An online survey to study usage, obstacles and requirements in Germany.

BACKGROUND AND OBJECTIVES: Molecular diagnostics (MDx) increasingly gains importance in dermatology and its application is a prerequisite for personalized medicine. The goal of this cross-sectional study was to determine how MDx is implemented in dermatologists' offices in the three fields of oncology, inflammation and infectiology and which hurdles office-based dermatologists face in terms of MDx. METHODS: Physician members of the Association of the German Dermatologists (Berufsverband der Deutschen Dermatologen e. V.; BVDD) were surveyed via an online questionnaire on MDx. RESULTS: 39.6 % of the 192 participants reported using MDx. Of these, the vast majority used MDx for diagnosing infectious diseases (86.5 % and 44.3 % of users perform MDx for detection of funghi and sexually transmitted diseases, respectively). Only a small minority applied MDx to answer oncological or immunological questions. The major obstacles for non-users as compared to users were difficulties in implementation, lack of expertise as well as time, personnel, and technical availability. Reimbursement was a main issue in both groups. CONCLUSIONS: Despite availability of specific therapies requiring precision medicine, MDx has not yet been broadly implemented in office-based dermatology. To advance MDx, more needs to be done in terms of continuous education, availability of reliable and valid tests, and reimbursability.

[Is the Bavarian Population Open for Teledermatology? A Cross-Sectional Study in Rural and Urban Regions of Bavaria, Germany]. / Wie offen ist die bayerische Bevölkerung für Teledermatologie? Eine Querschnittsstudie in ländlichen und städtischen Regionen Bayerns.

AIM: Teledermatology has a great potential to improve dermatologic care in rural regions. The aim of this study was to assess the willingness to use teledermatology in the rural population of Bavaria, Southern Germany, and to explore major concerns regarding teledermatology. METHODS: The data of this cross-sectional study were collected both as part of a health survey conducted in the Bavarian forest region in Q1/2017 and as part of a follow-up survey (Q1/2018) of a running cohort study recruited at a Bavarian agricultural festival. Study participants were asked in a standardized questionnaire whether they would send pictures of skin rashes or other skin changes to their dermatologist via the internet, and if "no", why not. RESULTS: Data on 1,116 participants living in Bavaria were analysed (mean age 50.2 years, 57.3% female, 80.4% living in rural regions). Of the whole sample, 36.6% were willing to use teledermatology. Women, older participants and participants living in rural regions were less open to the use of teledermatology. Major concerns regarding teledermatology were impersonality, doubts about the quality of the service and data safety and privacy concerns. DISCUSSION: The willingness to use teledermatology in the rural population of Bavaria is still rather low. Before teledermatology can realise its full potential for improving health care in rural regions, the population needs to be educated about the functioning and the advantages of teledermatology, and data safety concerns need to be addressed.

Retracing the COVID-19 Pandemic in Germany from a Public Perspective using Google Search Queries Related to "coronavirus".

AIM OF THE STUDY: During pandemics, the whole population is simultaneously confronted with the same health threat, resulting in enormous public interest. The current COVID-19 pandemic has left the world in a unique state of crisis. The aim of this analysis was to explore whether Google searches can be used to retrospectively retrace the COVID-19 pandemic in Germany and to detect local outbreaks by reflecting public interest in the virus. METHODS: Google Trends was used to explore the relative search volume (RSV) related to "coronavirus" from January 2020 to July 2020 in Germany. The RSV ranging between 0-100 was compared to new SARS-CoV-2 infections per day on a national level and to the cumulative infection numbers on a state level, as well as to important infectiological and political events. RESULTS: The most striking search peaks occurred after the first reported SARS-CoV-2 infection in Germany (January 27), during a major local outbreak in Heinsberg (February 25), after school closings (March 13) and the largest peak after nationwide contact restrictions (March 22) were announced. On a state level, peaks in RSV were observed after the first reported infection in each respective state. In addition, a higher RSV was recorded in states with higher numbers of infections (r=0,6, p=0,014) such as in Bavaria (RSV=96, 391 infections/100,000 inhabitants) and Baden-Württemberg (RSV=98, 340 infections/100,000 inhabitants). The lowest RSV (n=83) and lowest number of infections (50 infections/100,000 inhabitants) was observed in Mecklenburg-Western Pomerania. Since the end of May, SARS-CoV-2 related RSV remained at low level even when numbers of infections were temporarily rising due to local outbreaks such as the outbreak in Gütersloh, North Rhine-Westphalia. CONCLUSION: RSV related to "coronavirus" precisely reflected public interest during the beginning of the COVID-19 pandemic. As public interest has strongly declined, information distribution regarding the newest developments over the entire course of the pandemic will be a major public health challenge. ZIEL DER STUDIE: Während Pandemien ist die gesamte Gesellschaft zur gleichen Zeit mit derselben Erkrankung konfrontiert, was zu großem öffentlichen Interesse führt. Die aktuelle COVID-19 Pandemie hat die ganze Welt in einen einmaligen Ausnahmezustand versetzt. Ziel dieser Studie war es zu untersuchen ob das Pandemiegeschehen in Deutschland anhand von Google Suchanfragen retrospektiv rekonstruiert werden kann und ob lokale Ausbrüche mithilfe von Google Daten detektiert werden können. METHODIK: Das relative Google Suchvolumen (RSV) zum Thema "Coronavirus" wurde für den Zeitraum von Januar bis Juli 2020 mit Google Trends analysiert. Das RSV, das zwischen 0 und 100 betragen kann, wurde auf Bundesebene mit den täglich neu gemeldeten SARS-CoV-2 Infektionszahlen und auf Länderebene mit den kumulativen Infektionszahlen pro Bundesland sowie wichtigen infektiologischen und politischen Ereignissen verglichen. ERGEBNISSE: Höchstwerte im Google Suchvolumen nach der ersten gemeldeten SARS-CoV-2-Infektion in Deutschland (27. Januar), während des lokalen Ausbruchs in Heinsberg (25. Februar), nach den Schulschließungen (13. März) sowie, der absolute Höchstwert, nach Verkündung der bundesweiten Kontaktbeschränkungen (22. März) verzeichnet worden. Auf Bundesländerebene wurde immer dann ein Anstieg im Suchvolumen beobachtet, wenn die erste SARS-CoV-2 Infektion im jeweiligen Bundesland gemeldet wurde. Zudem wurde ein höheres RSV in Bundesländern mit mehr gemeldeten SARS-CoV-2-Infektionen registriert (r=0,6, p=0,014), wie z. B. in Bayern (RSV=96, 391 Infektionen/100 000 Einwohner) und Baden-Württemberg (RSV=98, 340 Infektionen/100 000 Einwohner). Das niedrigste RSV (n=83) und die niedrigste Anzahl an Infektionen (50 Infektionen/100 000 Einwohner) wurde in Mecklenburg-Vorpommern beobachtet. Seit Ende Mai ist das RSV bezüglich SARS-CoV-2 konstant gering, obwohl die Zahl an Neuinfektionen zwischenzeitlich aufgrund lokaler Ausbrüche gestiegen war wie z. B. der lokale Ausbruch in Gütersloh, Nordrhein-Westfalen. SCHLUßFOLGERUNG: Das RSV zum Thema "Coronavirus" bildeten das öffentliche Interesse während der ersten Monate der COVID-19 Pandemie präzise ab. Da das öffentliche Interesse jedoch stark nachgelassen hat, könnte es eine zentrale Herausforderung im weiteren Verlauf der Pandemie darstellen, die Bevölkerung weiterhin über neueste Entwicklungen und Maßnahmen informiert zu halten.

Genital Psoriasis and Associated Factors of Sexual Avoidance - A People-centered Cross-sectional Study in Germany.

Patients with genital psoriasis show poorer outcomes regarding quality of life and sexual distress than those without. This study aimed to assess the occurrence of genital psoriasis and to determine factors associated with the avoidance of sexual activities due to psoriasis in a non-clinical setting. A cross-sectional, person-centered, and online-based nationwide survey was conducted in Germany between March and June 2019. A multiple logistic regression model was used to analyze the data. Furthermore, free-text answers were provided. Overall, 344 individuals with psoriasis participated. Of these, 198 (57.6%) reported having genital psoriasis and 261 (75.9%) currently received medical care. Duration of psoriasis, subjective overall severity, and pain during sex were associated with the avoidance of sexual activities. Most prevalent reasons to avoid sexual activities were 'shame,' 'pain,' and 'fear of rejection.' Sexual distress was high in this sample and a person-centered care approach needs to be further promoted.

[Effects of an unconventional skin cancer prevention campaign : Impacts on the sun protection behavior of outdoor workers]. / Effekte einer unkonventionellen Hautkrebs-Präventionskampagne : Auswirkungen auf das Sonnenschutzverhalten von Außenberufstätigen.

BACKGROUND: The disease burden of actinic keratoses and keratinocyte carcinoma can be reduced by primary and secondary prevention. However, these measures are often poorly received, especially among the high-risk group of outdoor workers. OBJECTIVES: The aim of this follow-up study was to investigate whether an improvement in sun protection and awareness of skin changes could be observed among the study population, especially outdoor workers, one year after a prevention campaign focusing on this topic. MATERIALS AND METHODS: In 2017, all participants who initially participated in a study at the Bavarian Central Agricultural Festival 2016 and agreed to participate in the follow-up study were contacted by mail and received the same questionnaire and evaluation questions regarding possible behavioral changes. RESULTS: A total of 400 people took part in the follow-up study (response rate 52.8%). Of the 240 outdoor workers, 45.0% said they were more conscious of protecting themselves from the sun and 68.8% said they were more aware of skin changes. About 85.0% of outdoor workers indicated that they would consult a dermatologist earlier and 65.8% desired further prevention campaigns regarding skin cancer and sun protection. CONCLUSION: Overall, the majority of participants reported that they had improved sun protection behavior and awareness of skin changes after the intervention. Based on the participants' self-disclosure, especially outdoor workers tended to use sun protection measure more frequently. These findings underline the importance of target group-oriented awareness and prevention campaigns to reduce the burden of skin cancer.

Psoriasis 2.0: Facebook as a source of disease-related information for patients with psoriasis.

BACKGROUND AND OBJECTIVES: The Internet is a commonly used source of health-related information. Social media allow psoriasis patients to seek and share information about their disease. However, they also involve risks such as misinformation and envy. The aim of this study was to explore the relevance and suitability of Facebook as a source of disease-related information for patients with psoriasis. PATIENTS AND METHODS: Cross-sectional study consisting of an online survey (11/2017-01/2018). The link was published on a German information website focused on psoriasis. We also collected data about the respondents' general and disease-related Facebook habits as well as their assessment of opportunities and risks of Facebook in the context of psoriasis. RESULTS: 101 participants with psoriasis completed the questionnaire. Of these, 75 % reported using Facebook at least once a month, and 72 % of Facebook users stated that they had searched for disease-related information on Facebook. Active members of psoriasis-related Facebook groups deemed Facebook more helpful for coping with psoriasis. 60 % of Facebook users reported unreliable information and 57 % reported sales promotions regarding psoriasis when using Facebook. CONCLUSIONS: We found that Facebook is a relevant source of information for psoriasis patients. However, the quality of information offered seems insufficient and needs to be improved.

Psoriasis 2.0: Facebook als Quelle krankheitsbezogener Informationen für Patienten mit Psoriasis.

HINTERGRUND UND ZIELE: Das Internet ist eine gängige Informationsquelle bezüglich gesundheitlicher Themen. Soziale Medien ermöglichen es Patienten mit Psoriasis, Informationen über ihre Erkrankung zu suchen und auszutauschen. Ihre Nutzung geht jedoch auch mit Risiken wie Fehlinformation und Neid einher. Ziel dieser Studie war es, die Relevanz und Eignung von Facebook als Quelle krankheitsbezogener Informationen für Patienten mit Psoriasis zu untersuchen. MATERIAL UND METHODIK: Querschnittsstudie in Form einer Online-Befragung (11/2017-01/2018). Der Link wurde auf einer deutschen Psoriasis-Informationswebsite veröffentlicht. Daten über die allgemeine und krankheitsbezogene Facebook-Nutzung der Teilnehmer sowie deren Einschätzung der Chancen und Risiken von Facebook in Bezug auf Psoriasis wurden erhoben. ERGEBNISSE: 101 Teilnehmer mit Psoriasis haben den Fragebogen vollständig ausgefüllt. 75 % von ihnen berichteten, Facebook mindestens einmal pro Monat zu nutzen, und 72 % der Facebook-Nutzer gaben an, auf Facebook nach krankheitsbezogenen Informationen zu suchen. Aktive Mitglieder von Facebook-Gruppen mit Bezug zu Psoriasis bewerteten Facebook als nützlicher im Umgang mit der Erkrankung als andere Nutzer. 60 % der Facebook-Nutzer berichteten auf Facebook fragwürdigen Informationen über Psoriasis und 57 % Werbung mit Bezügen zu Psoriasis ausgesetzt zu sein. SCHLUSSFOLGERUNGEN: Laut den Ergebnissen dieser Studie ist Facebook eine relevante Informationsquelle für Patienten mit Psoriasis. Die Qualität der Informationen erscheint jedoch unzureichend und sollte deshalb verbessert werden.

Rate of individuals with clearly increased radiosensitivity rise with age both in healthy individuals and in cancer patients.

BACKGROUND: The question of an age dependence of individual radiosensitivity has only marginally been studied so far. Therefore, we analyzed blood samples of healthy individuals and cancer patients of different ages to determine individual radiosensitivity. METHODS: Ex vivo irradiated blood samples of 595 individuals were tested. Chromosomes 1, 2 and 4 were stained by 3-color fluorescence in situ hybridization and aberrations were analyzed. Radiosensitivity was determined by the mean breaks per metaphase (B/M). RESULTS: Healthy individuals (mean age 50.7 years) had an average B/M value of 0.42 ± 0.104 and an increase of 0.0014B/M per year. The patients (mean age 60.4 years) had an average B/M value of 0.44 ± 0.150 and radiosensitivity did not change with age. In previous studies we found that from a value of 0.6B/M on an individual is considered to be distinctly radiosensitive. The portion of radiosensitive individuals (B/M > 0.6) increased in both cohorts with age. CONCLUSION: Individual radiosensitivity rises continuously with age, yet with strong interindividual variation. No age related increase of radiosensitivity can be demonstrated in patients due to the strong interindividual variation. However among old cancer patients there is a higher probability to have patients with clearly increased radiosensitivity than at younger age.

What Do Germans Want to Know About Skin Cancer? A Nationwide Google Search Analysis From 2013 to 2017.

BACKGROUND: Experts worldwide agree that skin cancer is a global health issue, but only a few studies have reported on world populations' interest in skin cancer. Internet search data can reflect the interest of a population in different topics and thereby identify what the population wants to know. OBJECTIVE: Our aim was to assess the interest of the German population in nonmelanoma skin cancer and melanoma. METHODS: Google AdWords Keyword Planner was used to identify search terms related to nonmelanoma skin cancer and melanoma in Germany from November 2013 to October 2017. The identified search terms were assessed descriptively using SPSS version 24.0. In addition, the search terms were qualitatively categorized. RESULTS: A total of 646 skin cancer-related search terms were identified with 19,849,230 Google searches in the period under review. The search terms with the highest search volume were "skin cancer" (n=2,388,500, 12.03%), "white skin cancer" (n=2,056,900, 10.36%), "basalioma" (n=907,000, 4.57%), and "melanoma" (n=717,800, 3.62%). The most searched localizations of nonmelanoma skin cancer were "nose" (n=93,370, 38.99%) and "face" (n=53,270, 22.24%), and the most searched of melanoma were "nails" (n=46,270, 70.61%) and "eye" (n=10,480, 15.99%). The skin cancer‒related category with the highest search volume was "forms of skin cancer" (n=10,162,540, 23.28%) followed by "skin alterations" (n=4,962,020, 11.36%). CONCLUSIONS: Our study provides insight into terms and fields of interest related to skin cancer relevant to the German population. Furthermore, temporal trends and courses are shown. This information could aid in the development and implementation of effective and sustainable awareness campaigns by developing information sources targeted to the population's broad interest or by implementing new Internet campaigns.

Disease-Related Internet Use and its Relevance to the Patient-Physician Relationship in Atopic Dermatitis: A Cross-Sectional Study in Germany.

Background: Health-related internet use presents both opportunities and challenges for patients and physicians and requires a comprehensive understanding to improve individual health care in atopic dermatitis (AD). Objective: To explore differences between regular and irregular disease-related internet users, reasons for disease-related internet use, and its relevance to the patient-physician relationship in AD. Methods: This cross-sectional study recruited 221 adults with AD online and from a German university clinic between August 2021 and February 2022. The questionnaire queried sociodemographic and disease-related information, reasons for and against using the internet, types of channels used, and the impact on the patient-physician relationship. Participants were categorized as regular (≥once per month) and irregular (

Chromosomal radiosensitivity in oncological and non-oncological patients with rheumatoid arthritis and connective tissue diseases.

BACKGROUND: The risk of developing late radiotoxicity after radiotherapy in patients with high chromosomal radiosensitivity after radiotherapy could potentially be higher compared to the risk in patients with average radiosensitivity. In case of extremely high radiosensitivity, dose reduction may be appropriate. Some rheumatic diseases (RhD), including connective tissue diseases (CTDs) appear to be associated with higher radiosensitivity. The question arises as to whether patients with rheumatoid arthritis (RA) also generally have a higher radiosensitivity and whether certain parameters could indicate clues to high radiosensitivity in RA patients which would then need to be further assessed before radiotherapy. METHODS: Radiosensitivity was determined in 136 oncological patients with RhD, 44 of whom were RA patients, and additionally in 34 non-oncological RA patients by three-colour fluorescence in situ hybridization (FiSH), in which lymphocyte chromosomes isolated from peripheral blood are analysed for their chromosomal aberrations of an unirradiated and an with 2 Gy irradiated blood sample. The chromosomal radiosensitivity was determined by the average number of breaks per metaphase. In addition, correlations between certain RA- or RhD-relevant disease parameters or clinical features such as the disease activity score 28 and radiosensitivity were assessed. RESULTS: Some oncological patients with RhD, especially those with connective tissue diseases have significantly higher radiosensitivity compared with oncology patients without RhD. In contrast, the mean radiosensitivity of the oncological patients with RA and other RhD and the non-oncological RA did not differ. 14 of the 44 examined oncological RA-patients (31.8%) had a high radiosensitivity which is defined as ≥ 0.5 breaks per metaphase. No correlation of laboratory parameters with radiosensitivity could be established. CONCLUSIONS: It would be recommended to perform radiosensitivity testing in patients with connective tissue diseases in general. We did not find a higher radiosensitivity in RA patients. In the group of RA patients with an oncological disease, a higher percentage of patients showed higher radiosensitivity, although the average radiosensitivity was not high.
