Psychiatric Comorbidity, Sexual Dysfunction, and Quality of Life in Patients Undergoing Hemodialysis: A Case-Control Study.

INTRODUCTION Due to disabilities caused by the disease and the requirement of dialysis, end-stage renal disease (ESRD) is frequently comorbid with psychiatric disorders, adversely affects quality of life, and causes significant sexual dysfunction (SD). We aimed to investigate the psychiatric comorbidity, quality of life, depression and anxiety levels, and SD in ESRD patients undergoing hemodialysis. METHODS Forty-nine patients undergoing hemodialysis treatment in a dialysis center and 44 non-ESRD control subjects selected with snowball sampling were enrolled in the study. All subjects were assessed using Structured Clinical Interview for Axis-I Disorders (SCID-I). Sociodemographic data form, Hospital Anxiety and Depression Scale (HADS), Arizona Sexual Experience Scale (ASEX), and World Health Organization Quality of Life Short Form Turkish Version Scale (WHOQOL-BREF-TR) were applied to both groups. RESULTS There was no difference between the groups in terms of sex, age, education period, marital status, presence of additional physical illness, and past history of psychiatric disorders. Compared with the control group, HADS depression subscale and ASEX scores were significantly high (p<0.01) in the patient group, and WHOQOL-BREF-TR psychological and physical domain scores were low (p<0.05 and p<0.01, respectively). There was a significant negative relationship between HADS scores and WHOQOL-BREF-TR psychological, environmental, and national environmental scores in the patient group (p<0.05). When the differences between the groups were re-analyzed after controlling HADS depression scores with covariance analysis, the significant difference in ASEX and WHOQOL-BREF-TR physical domain scores between the groups remained, but the significant difference in WHOQOL-BREF-TR psychological domain scores disappeared. CONCLUSION The quality of life of ESRD patients was lower, especially in the psychological and physical domains, and psychiatric comorbidities and SD rates were higher than in non-ESRD control subjects. Quality of life is affected by SD. Recognizing and treating depressive symptoms will help improve the quality of life, especially in the psychological domain.
