IntroductionThe aims of this study were to evaluate levels of health-related quality of life (HRQOL) and the presence of anxiety and depressive symptoms in children with primary immunodeficiency disease (PID) in Serbia.Materials and methodsSelf- and parent-rated data from 25 children with PID were available. As controls, data from 50 children with juvenile idiopathic arthritis (JIA) and 89 healthy children were included. The Pediatric Quality of Life Inventory was used for HRQOL assessments. Anxiety symptoms were identified using the Screen for Child Anxiety-Related Emotional Disorders questionnaire, while depressive symptoms were identified using the Mood and Feeling Questionnaire.ResultsChildren with PID had significantly lower Pediatric Quality of Life Inventory total scores compared to children with JIA and healthy children as child-rated (P=0.02) and parent-rated (P<0.001). Specifically, they had significantly lowered emotional functioning compared to children with JIA, and social functioning compared to both children with JIA and healthy children. School functioning was significantly lower among children with PID (parent-rated only). By parent-rated responses, six (24%) out of 25 children with PID had significant anxiety symptoms, while five (20%) children had significant depressive symptoms, which was statistically higher than among children with JIA and healthy controls (P=0.05).ConclusionHRQOL could be significantly compromised in children with PID, particularly across such psychosocial domains as emotional, social, and school. These children were also found to be at an increased risk for suffering significant anxiety and depressive symptoms.

Anxiety may be present as an isolated symptom, with specific demographic and clinical markers, and not only as a feature of depression in PD population. This highlighted the importance of identifying anxiety symptoms when treating patients with PD.

Summary Background: Endocrine system plays a major role in both permissive and regulatory activities in order to adequately respond to physical stress of exercise. But level and direction of activation depend on many factors and are not easily interpreted. Methods: We tested a group of male professional athletes (21 water polo players and 15 wrestlers), together with 20 sedentary controls matched by age. All participants took a continuous progressive exercise stress test on a treadmill until exhaustion and plateau of oxygen consumption (VO2). Blood samples for cortisol, sex hormone binding globulin (SHBG) and testosterone were drawn in four time points: baseline (B), start of the test (S), point of maximal strain (MAX) and in the 3rd minute of recovery period (R). Results: Cortisol levels significantly increased in both groups, but the response between S and MAX was more pronounced in controls (p=0.036). The athletes had significantly higher levels of cortisol in all points in test, except during R (p=0.118), when their cortisol levels gradually started to decline. Significant increase in total testosterone was in great deal a consequence of increase in SHBG level (p<0.01 for both). Consequently, calculated free testosterone significantly decreased during test (p=0.008), and the drop was more pronounced in athletes. This was in concordance with significant correlation between SHBG and cortisol level demonstrated in athletes, but not in controls. Conclusions: It seems that high intensity endurance exercise favors catabolic response, but the level of response highly depends on a previous level of training.

Occasionally calcifications in abdominal organs, breasts and testicles have been reported in pseudoxanthoma elasticum (PXE) patients. In the present study, an ultrasound evaluation was performed of the abdomen and--in male patients--of the testicles in 17 PXE patients and 17 heterozygous carriers. Blood samples were taken to evaluate calcium load, liver and kidney function. Calcifications in liver, kidneys and spleen were detected in 59% of the patients and in 23.5% of healthy carriers. Parameters of kidney and liver function were normal in both groups, suggesting that the calcifications have no direct effect on organ function. Testicular ultrasound revealed parenchymous calcifications in all males investigated. Widespread, small hyperechogenic foci resembling testicular microlithiasis were seen. In some carriers, focal calcifications were identified. The current data suggest that visceral and testicular calcifications are part of the phenotype of PXE patients. Their presence in some of the healthy carriers are suggestive of subclinical manifestations in these relatives. The natural history and long-term effects of the parenchymal calcifications remain to be elucidated. As testicular microlithiasis may be associated with a higher risk for malignancy, regular clinical and ultrasound follow-up seems indicated in these patients.
