Background Health-Related Quality of Life (HRQoL) in patients with chronic kidney disease (CKD) is significantly affected, regardless of the stage of the disease, as regards the physical, psychological and social functioning dimension. Big-Five personality traits can affect patients’ HRQoL and willingness to take treatment options. Illness denial consists of denial of negative emotions, resistance to change and conscious avoidance. Poorer HRQoL can predict a higher risk of hospitalization and mortality, and broadly a worse adjustment to the dialytic therapy. Thus, a clearer knowledge of the psychological variables associated with a worse HRQoL in the predialysis stage might improve the intervention planning. No study investigated illness denial and personality traits simultaneously. We investigated the role of illness denial and Big-Five personality traits in the domains of HRQoL in predialysis patients with CKD. Methods One hundred adults (mean age: 75.87 years) with CKD participated. The Kidney Disease Quality of Life Short form, the Italian version of Ten Item Personality Inventory Revised, the Illness Denial Questionnaire, and the State-Trait Anxiety Inventory Form-Y were administered. Results Illness denial was associated with increased HRQoL related to symptoms/problems, effect and burden of CKD and cognitive functions domains, and it was a predictor of higher HRQoL in the last three domains mentioned above. Extraversion was related to better work status and sexual function; agreeableness was linked to elevated cognitive function, quality of social interaction and sexual function; conscientiousness was related to better sexual function; neuroticism was linked to improved cognitive and sexual functions; in the end, openness to experience was related to fewer symptoms and problems. Conclusions This is the first study which simultaneously assessed Big-Five personality traits and illness denial in different domains of HRQoL of CKD patients. Personalised psychological interventions aimed at improving HRQoL in this population might focus on specific illness denial processes and personality traits.

Introduction A young male was found dead on the bed of a hotel room. He was expected to take part in a bodybuilding competition the day after. During the site inspection, drugs of different types were found. The next day, an autopsy was performed. The evidence of cardiomegaly with organ congestion involving lung, liver, kidneys, adrenal glands, spleen and brain was confirmed by both the autoptic and the histopathological exam. However, the cause of death needed to be investigated. Methods A thorough toxicological investigation was undertaken by gas chromatography–mass spectrometry (GC‐MS), liquid chromatography‐high resolution mass spectrometry (LC‐HRMS) and liquid chromatography–tandem mass spectrometry (UPLC‐MS/MS) on samples of urine, blood and hair. Results and discussion Clenbuterol, a long‐acting selective beta2 agonist, was found in both blood (1 ng/ml) and urine (1 ng/ml), and evidence of its use was provided by the analysis of the 3‐cm hair (25 pg/mg). The main metabolite of drostanolone (2 alpha‐methyl‐androsterone), an anabolic steroid, was found in the urine (202 ng/ml), where an increased ratio of testosterone/epitestosterone (T/E = 11) emerged. Due to the results of the hair analysis, a long‐term use of various anabolic steroids was supposed. The integrated analysis of the results and the absence of other possible causes (such as trauma or cardiac conduction anomalies) led to the identification of the abuse of doping substances as the underlying cause of death. Conclusion Hair analysis has proven to be crucial in identifying drug misuse and the contributing cause of death.

Background. Health-Related Quality of Life (HRQoL) in patients with chronic kidney disease (CKD) is significantly affected, regardless of the stage of the disease, as regards the physical, psychological and social functioning dimension. Big-Five personality traits can affect patients’ HRQoL and willingness to take treatment options. Illness denial consists of denial of negative emotions, resistance to change and conscious avoidance. No study investigated illness denial and personality traits simultaneously. We investigated the role of illness denial and Big-Five personality traits in the domains of HRQoL in predialysis patients with CKD.Methods. One hundred adults (mean age: 75.87 years) with CKD participated. Poorer HRQoL can predict a higher risk of hospitalization and mortality, and broadly a worse adjustment to the dialytic therapy. Thus, a clearer knowledge of the psychological variables associated with a worse HRQoL in the predialysis stage might improve the interventions planning. The Kidney Disease Quality of Life Short form (KDQOL-SF), the Italian version of Ten Item Personality Inventory (I-TIPI), the Illness Denial Questionnaire (IDQ), and the State-Trait Anxiety Inventory Form-Y (STAI-Y) were administered. Results. Illness denial was associated with increased HRQoL in symptoms, effect, burden of kidney disease and cognitive functions domains, and it was a predictor of higher HRQoL in the last three domains mentioned above. Extraversion was related to better work status and sexual function; agreeableness was linked to elevated cognitive function, quality of social interaction and sexual function; conscientiousness was related to better sexual function; neuroticism was linked to improved cognitive and sexual functions; in the end, openness to experience was related to fewer symptoms and problems.Conclusions. This is the first study which simultaneously assessed Big-Five personality traits and illness denial in different domains of HRQoL of CKD patients. Personalised psychological interventions aimed at improving HRQoL in this population might focus on specific illness denial processes and personality traits.
