OBJECTIVE: This paper aims to examine the association between painful physical symptoms (PPS) and major depressive disorder (MDD) in a naturalistic clinical practice setting within a Korean population. METHODS: Patients with acute MDD that joined a multicountry, observational, three-month study in six Asian countries and regions were classified as PPS+ (mean score > or =2) and PPS- (mean score <2) using the modified Somatic Symptom Inventory. In this analysis, we report the results from the Korean subset, where depression severity was assessed using the Clinical Global Impression of Severity (CGI-S) scale and 17-item Hamilton Depression Rating Scale (HAMD(17)). Pain severity was measured using a visual analogue scale (VAS), while the EuroQoL (EQ-5D) assessed patient well-being. RESULTS: Of 198 patients, 45.96% (91/198) of patients were classified as PPS+, of which 78.02% (71/91) were women. PPS+ patients had significantly more severe depression at baseline {CGI-S score, mean [standard deviation (SD)], PPS+: 5.09 [0.79]; PPS-: 4.63 [0.76]; p<0.001; HAMD(17) total score, mean [SD], PPS+: 24.34 [5.24]; PPS-: 20.76 [5.12]; p<0.001} and poorer quality of life [EQ-5D overall health state, mean (SD), PPS+: 39.37 (20.52); PPS-: 51.27 [20.78]; p<0.001] than PPS- patients. Both groups improved significantly (p<0.001) in depression and pain severity outcomes, as well as quality of life by endpoint, but no significant within-group baseline-to-endpoint change wase observed. CONCLUSION: The frequency of PPS was common in Korean patients with MDD, and was associated with more severe depression, poorer quality of life, and a trend towards poorer clinical outcome.

BACKGROUNDPainful physical symptoms (PPS) may present as a component of major depressive disorder (MDD). Their effect in Chinese patients has not been investigated. This analysis reports the changes in disease severity, treatment patterns, quality of life and outcomes in a Chinese cohort according to the presence (PPS+) or absence (PPS-) of painful physical symptoms.

METHODSA subgroup of Chinese patients from a large observational 3-month study of patients from Asian countries and regions of China were classified using the modified Somatic Symptom Inventory (SSI) as PPS+ (mean score >or= 2) or PPS- (mean score < 2). Depression severity was assessed with the Clinical Global Impression of Severity (CGI-S) scale and 17-item Hamilton depression rating scale (HAMD(17)). Pain severity was measured using a visual analogue scale (VAS), while the EuroQoL (EQ-5D) assessed patient well-being. Antidepressants were compared with regard to their efficacy.

RESULTSOf the 299 Chinese patients enrolled in the study, 105 were classified as PPS+ (73/105, 70% women). At baseline, PPS+ patients reported greater pain severity (VAS, mean (SD): 49.56 (26.49) vs. 16.60 (20.99) for PPS-, P < 0.01), were more depressed (HAMD(17), mean (SD): 25.32 (5.47) vs. 23.33 (5.24) for PPS-, P = 0.002) and had poorer quality of life (EQ-5D Health State, mean (SD): 38.48 (22.38) vs. 49.57 (18.54) for PPS-, P < 0.001). PPS+ patients showed less overall improvement in depressive symptom severity (HAMD(17), change from baseline (95%CI): -17.38 (-18.65, -16.12) vs. -19.20 (-20.05, -18.35) for PPS-, P = 0.032; CGI-S, change from baseline (95%CI): -2.85 (-3.11, -2.58) vs. -3.20 (-3.38, -3.02) for PPS-, P = 0.044).

CONCLUSIONSPPS were less frequent than expected compared with previous studies of Asian populations. PPS+ were associated with greater MDD severity and less improvement than PPS- when antidepressants were given.
