Background: Polymorphonuclear leucocytes are the first line of defence against foreign invaders and constitute the major cell type involved in certain types of acute and chronic inflammatory diseases. Aim of the Work: The aim of the present study was to investigate the changes in expression of BCL-2 and BAK genes by real time PCR and to study whether they were involved in the accelerated neutrophil apoptosis which might be responsible for the recurrent bacterial infections seen in chronic renal disease and hemodialysis patients. Subjects and Methods: This study was conducted on sixty two subjects. Patients were selected from those admitted to Theodor Bilharz Research Institute (TBRI). Patients under study were classified into three groups; CKD patients (group I) kept on conservative treatment (22 cases), ESRD patients (group II) maintained on dialysis therapy, HD (20 cases). In addition, twenty healthy individuals served as a control group (group III) were involved. Results: There was significant increase in level of BAK gene in both patients' groups compared to control group with more increase in CKD group than ESRD group. Significant difference between the 3 groups was encountered with a higher expression level in CKD and ESRD groups than controls. There was decrease in level of BCL2 gene in both groups less than control group with more declines in ESRD group than CKD group. Conclusion: Bcl2 and Bak genes could have a role in survival and apoptosis of the studied groups and suggested their impact in controlling the inflammatory mechanisms and eventually their therapeutic potential.

Background. Emotional deterioration is frequently found in patients with chronic kidney disease, but some patients are affected by depressed mood without fulfilling the criteria of a depressive disorder. Those patients might rather suffer from an apathy symptom. Apathy as a symptom of a medical disease is accompanied by loss of motivation and interest, cognitive impairments, and emotional distress. Our study tested how groups of apathetic and depressed chronic kidney disease patients responded to a single haemodialysis session on measures of mood. Methods. 21 haemodialysis patients were assigned to subgroups (depressed, apathetic only, without depression and apathy) according to clinical relevant cut-offs. Sensitive questionnaires were administered to monitor mood state in general and mood changes before and after a single haemodialysis session in the chronic kidney disease patients. The results were compared to 20 age-matched healthy controls receiving no treatment. Results. Fortheen dialysis patients had eighter apathy or depressen and seven had neighter apathy nor depression. Mood state was seriously affected in all haemodialysis patients with depressed patients showing the largest effect compared to healthy controls. Patients with apathy and patients without apathy and depression were comparable in their mood state. We observed a positive mood change after the haemodialysis only in patients without apathy and depression. Their mood state improved significantly and reached nearly the level of healthy controls. Conclusions. The absence of a short-term mood change in apathetic dialysis patients makes them comparable to dialysis patients with depression. We argue that apathetic patients lack the probable mood brightening effect of the haemodialysis. The lack of emotional improvement by dialysis sessions could also lead to decreased adherence of the patients. Hence, apathy seems to be a serious symptom in chronic kidney disease that is worth to be considered at least in the diagnostic process. Accompanying psychotherapeutic care for these patients would be desirable
