Depression in patients receiving peritoneal dialysis.

Area of Science:

• Nephrology
• Psychiatry
• Epidemiology

Background:

• Peritoneal dialysis (PD) is a vital treatment for end-stage renal disease.
• Depression is a common comorbidity in patients with chronic illnesses, impacting quality of life and treatment adherence.
• Identifying depression prevalence and correlates in Chinese PD patients is crucial for targeted interventions.

Purpose of the Study:

• To determine the prevalence of current and past major depressive episodes in Chinese PD patients.
• To identify socio-demographic and clinical factors associated with elevated depressive symptoms in this population.

Main Methods:

• A cross-sectional study involving 141 Chinese PD patients from October 2007 to June 2008.
• Utilized the Chinese bilingual Structured Clinical Interview for DSM-IV (Axis I) for diagnosing major depressive disorders.
• Assessed co-morbid illnesses using the Cumulative Illness Rating Scale and perceived social support via the Multidimensional Scale of Perceived Social Support (MSPSSC).

Main Results:

• The point prevalence of a current major depressive episode was 16%.
• An additional 21% of patients reported at least one past episode of major depression.
• Independent correlates of depressive symptoms included low perceived social support (MSPSS-C score), muscle cramps, chronic back pain, joint stiffness, and receipt of Social Security Allowance.

Conclusions:

• Chinese patients undergoing peritoneal dialysis exhibit a higher prevalence of depression.
• Identifying specific correlates such as low social support and physical symptoms can assist clinicians in recognizing and managing depression in busy renal clinics.
