Correlation between serum renin-angiotensin system (RAS) level and depression and anxiety symptoms in patients with Parkinson's disease.

Abstract

To investigate the correlation between serum renin-angiotensin system (RAS) level and Symptoms of anxiety and depression in Parkinson disease patients (PD). A number of 90 PD patients (47 males and 43 females) were collected on an empty stomach 12 h after stopping taking anti-PD medicines. ELISA has been found in Serum RAS ((Ang) I, Ang II, Ang (1–7), Angiotensin converting enzyme (ACE), ACE2). Depression scale (HAMD) and Anxiety scale (HAMA) in Hamilton are used for the assessment of signs of depression and anxiety. The 90 patients were diagnosed with moderate depression (HAMD score 8 ~ 19); in 32 of those (35.56 percent), and 12 (13.33%) were diagnosed as moderate and severe depression (HAMD score ≥ 20). 20 cases (22.22%) were diagnosed as possible anxiety disorder (HAMA score 7 ~ 13) and 16 cases (17.78%) as definite anxiety disorder (HAMA score ≥ 14). The association of serum Ang I, Ang II and Ang (1–7) with HAMD (r= − 0.820, P < 0.001; r = −0.846, P < 0.001) showed negative linkage with HAMD (r = −0.887, P < 0.003; P < 0.001; Negative correlation of the settings with HAMA (r = −0.850, P < 0.001; r = −0.887, P < 0.001; r = 0.003; r = 0.001, P < 0.001, Fig. 2, Fig. 3); The HAMD score and the HAMA score (all P > 0.05) were not associated to the serum ACE and ACE2. The serum Ang I, Ang II, and Ang (1–7) were found to be adversely associated with HAMD score (r = 0.826, P < 0,001; r = −0.818, p> >0,001; r = −0.876, P < 0,001; P = 0,001) P < 0,001; And have been negatively correlated (r = 0.870, Fig. 1, Fig. 2, Fig. 3) with AMA-scores (r = −0.876, P < 0.001, Table 1, Fig. 3), R = −0.862, P > 0.001; The HAMD score and the HAMA score (all P > 0.05) were not correlated to the serum ACE and ACE2. Finally, in PD patients, non-engine signs, including depression and anxiety, are normal. Thus, Serum levels Ang I, Ang II and Ang (1–7) were substantially decreased in female and male patients and associated with symptoms of depression and anxiety, ACE and ACE2 levels have not been attributed to signs of depression and anxiety. Serum Ang I, Ang II, and Ang (1–7) are important markers of depression and anxiety prevention and diagnosis in patients with DP.
