ABSTRACT
BACKGROUND: Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disorder with varied clinical courses and prognoses, not only did the patients suffer from physical impairment, but also various physical and psychiatric comorbidities. Growing evidence have suggested that mental disorders in SLE patients, can lead to various adverse consequences. AIM: To explored the features and influencing factors of mental health in patients with SLE and clarifying the correlations between mental health and personality characteristics and perceived social support. The results would provide a basis for psychological intervention in patients with SLE. METHODS: The clinical data of 168 patients with SLE admitted at the First Affiliated Hospital of Hainan Medical University between June 2020 and June 2022 were collected. Psychological assessment and correlation analysis were conducted using the Symptom Checklist-90 (SCL-90) and Perceived Social Support Scale, and the collected data were compared with the national norms in China. The relevant factors influencing mental health were identified by statistical analysis. A general information questionnaire, the Revised Life Orientation Test, and Short-Form 36-Item Health Survey were employed to assess optimism level and quality of life (QoL), respectively. RESULTS: Patients with SLE obtained higher scores for the somatization, depression, anxiety, and phobic anxiety subscales than national norms (P < 0.05). A correlation was identified between total social support and total SCL-90 score or each subscale (P < 0.05). The factors significantly affecting patients' mental health were hormone dosage and disease activity index (DAI) (P < 0.05). The average optimism score of patients with SLE was 14.36 ± 4.42, and 30 cases were in the middle and lower levels. A positive correlation was found between optimism level and QoL scores. CONCLUSION: Patients with SLE develop psychological disorders at varying degrees, which are significantly influenced by hormone dosage and DAI. Patients' mental health should be closely monitored during clinical diagnosis and treatment and provided adequate support in establishing positive, healthy thinking and behavior patterns and improving their optimism level and QoL.
ABSTRACT
BACKGROUND: The purpose of this study was to determine the association between single nucleotide polymorphisms (SNPs) at the rs4331, rs4341, and rs4351 loci of the angiotensinconverting enzyme (ACE) gene and genetic susceptibility to systemic lupus erythematosus (SLE) in the Hainan population. METHODS: This study involved a total of 428 participants, with 214 individuals diagnosed with SLE and an equal number of healthy controls. The SNaPshot sequencing technique was used to determine the base sequences at the ACE gene rs4331, rs4341, and rs4351 loci in the study subjects. Logistic regression was employed to compare the frequency distribution of genotypes and allele frequencies at each locus between the case group and the control group. HaploView 4.2 software was used to analyze the relationship between haplotypes at each locus and genetic susceptibility to SLE. RESULTS: The GG genotype and G allele frequency at the rs4341 locus were higher in the case group compared to the control group. In the rs4341 recessive model, carriers of the GG genotype were more likely to develop SLE compared to carriers of the CG+CC genotype (OR = 1.889, 95% CI: 1.195-2.988, P = 0.006). In the rs4351 overdominant model, carriers of the AC genotype had an increased risk of developing SLE compared to carriers of the AA+CC genotype (OR = 1.514, 95% CI: 1.033-2.219, P = 0.033). The rs4341 and rs4351 loci exhibited linkage disequilibrium, and the CA haplotype (OR = 0.630, 95% CI: 0.481-0.826, P = 0.001) was a protective factor against SLE. The GA haplotype (OR = 2.849, 95% CI: 1.901-4.270, P < 0.01) and the CC haplotype (OR = 2.309, 95% CI: 1.210-4.405, P = 0.009) were risk factors for genetic susceptibility to SLE in the Hainan population. CONCLUSION: The rs4341 locus of the ACE gene is associated with genetic susceptibility to SLE in the Hainan population.
ABSTRACT
To investigate the correlation between susceptibility to systemic lupus erythematosus (SLE) and single nucleotide polymorphisms (SNPs) rs699, rs4762 and rs1926723 in the AGT gene in the population of Northeast China, while also introducing a new method for early detection of SLE. A total of 856 cases of SLE patients and healthy volunteers who attended the First Affiliated Hospital of Harbin Medical University from January 2020 to December 2022 were recruited. Clinical information and biood samples were collected from particpants in this study. SNaPshot sequencing technology was used to sequence the bases of the rs699, rs4762 and rs1926723 in the AGT gene. The genetic stability of SNPs was analysed by means of Hardy-Weinberg (HWE) genetic equilibrium. The study examined the correlation between genetically stable SNPs and susceptibility to SLE using logistic regression analysis. Rs699 did not adhere to the principles of the HWE genetic equilibrium (p < .01). Conversely, both rs4762 and rs1926723 conformed to the HWE genetic equilibrium (p > .05). However, no significant differences in genotypes and alleles frequencies of the rs4762 were observed between the two groups (p > .05). Furthermore, there was a significant difference in the distribution of AG, GG genotypes frequency and G allele frequency at the rs1926723 between the two groups (p < .001). Individuals with AG and GG genotypes and the G allele had a significantly lower frequency of SLE, indicating a potential genetic protective factor against susceptibility to the SLE. The SNPs rs1926723 may be linked to the susceptibility to SLE, and the AG, GG genotypes and the G allele may be important protective factors for the development of SLE in Northeast China.
