Shedding Light on the Role of ERAP1 in Axial Spondyloarthritis.

Spondyloarthritis (SpA) is a multifactorial chronic inflammatory disease affecting the axial skeleton (axSpA) and/or peripheral joints (p-SpA) and entheses. The disease's pathogenesis depends on genetic, immunological, mechanical, and environmental factors. Endoplasmic reticulum aminopeptidase 1 (ERAP1) is a multifunctional enzyme that shapes the peptide repertoire presented by major histocompatibility complex (MHC) class I molecules. Genome-wide association studies (GWAS) have identified different single nucleotide polymorphisms (SNPs) in ERAP1 that are associated with several autoimmune diseases, including axSpA. Therefore, a deeper understanding of the ERAP1 role in axSpA could make it a potential therapeutic target for this disease and offer greater insight into its impact on the immune system. Here, we review the biological functions and structure of ERAP1, discuss ERAP1 polymorphisms and their association with axSpA, highlight the interaction between ERAP1 and human leukocyte antigen (HLA)-B27, and review the association between ERAP1 SNPs and axSpA clinical parameters.

Association of perceived neighborhood characteristics, socioeconomic status and rural residency with health outcomes in Egyptian patients with systemic lupus erythematosus: one center study.

OBJECTIVE: To investigate the role of perceived neighborhood characteristics, socioeconomic status (SES) and rural residency in influencing the health status outcome of Egyptian patients with systemic lupus erythematosus (SLE). METHODS: Eighty patients affected with SLE were consecutively included in this a single-center cross-sectional study from July, 2011 to July, 2013. Outcome measures included the Systemic Lupus Activity Questionnaire (SLAQ) score, the Medical Outcomes Study Short Form-36 Health Survey physical functioning score and Center for Epidemiologic Studies-Depression (CES-D score of ≥ 19 points). Multivariate logistic regression analyses were conducted. RESULTS: Results from multivariate logistic regression analyses, a separate adjusted model of each perceived neighborhood characteristic, indicate associations of worse perceived social cohesion with higher SLAQ scores (P < 0.01) and associations of worse perceived neighborhood aesthetics and safety with lower SF-36 physical functioning scores after adjusting for covariates (P < 0.01). Regarding the association of socioeconomic status and rural residency with health status outcomes, the results found association of poor socioeconomic status with the three health status outcome measures and association between rural residency and depression symptoms. Individuals had increased odds of depressive symptoms if they perceived worse neighborhood social cohesion (odds ratio [OR]: 2.14; CI: 1.42-2.80), if they perceived worse neighborhood safety (OR: 1.64; CI: 1.02-2.40) and if they perceived worse neighborhood aesthetic characteristics (OR: 2.79; CI: 1.84-3.38). CONCLUSIONS: Study findings indicate that poor socioeconomic status, rural residency and perceived neighborhood characteristics are associated with depression; worse perceived neighborhood aesthetics and safety are associated with lower SF-36 physical functioning, and worse neighborhood social cohesion is associated with higher disease activity among patients with SLE.

Determinants of medication non-adherence in Egyptian patients with systemic lupus erythematosus: Sharkia Governorate.

The aim of the study was to identify the determinants of adherence to medication among Egyptian patients with SLE. A single-center cross-sectional study was conducted among Egyptian patients with SLE. Adherence to medication was measured via The Compliance Questionnaire for Rheumatology-19, and the patients were classified as non-adherers if they were taking <80% of their medication correctly. Predictors of adherence to SLE medication were determined by multiple logistic regressions. The mean age of participants was 30.9 ± 11.7 years. Females constituted 95% of all participants. Thirty-eight (%) were taking <80% of their medication correctly. On logistic regression analysis, the significant independent predictors of medication non-adherence were lower educational level (OR 5.6, 95% CI 2.1-7.3, P < 0.001), very low and low socioeconomic status (OR 2.6, 95% CI 1.6-4.3, P < 0.04), rural residency (OR 3.4, 95% CI 1.4-5, P < 0.01), more number of medications (OR 3.2, 95% CI 2.3-6.9, P < 0.01), and higher depressive symptoms (OR 3.7, 95% CI 1.4-10.2, P < 0.001). The adherence rate reported in this study was quite low. Appropriate adherence enhancing intervention strategies targeted at reducing pill load, minimizing depressive symptoms, and ensuring an uninterrupted access to free services regimen for patients with low socioeconomic status is strongly recommended. More attention should be given to SLE patients who live in rural regions.

Predictors of functional outcome in patients with traumatic spinal cord injury after inpatient rehabilitation: in Saudi Arabia.

OBJECTIVE: To identify the possible factors influencing motor functional outcome of patients with traumatic spinal cord injury (T-SCI) after inpatient rehabilitation. METHODS: 90 patients with T-SCI consecutively admitted for inpatient SCI rehabilitation unit was studied. Demographic characteristics, level and completeness of SC injury using American Spinal Injury Association (ASIA) Impairment Scale, disability level using Functional Independence Measure (FIM), psychological state using Hospital Anxiety and Depression Scale (HADS), and SCI-related medical complications were assessed and recorded at admission. The main measure of functional outcome was the motor FIM gain score at discharge. The univariate and multiple linear regression analyses were performed. RESULTS: The Mean admission motor FIM score was 35.3 (20.1), the mean discharge motor FIM score was 65.3 (22.5), and the mean motor FIM gain score was 30.0 (20.9). Univariate analyses indicated that the significant factors influencing motor functional outcome included age, motor FIM score at admission, level and severity of injury, anxiety/depression score, time between injury and admission to rehabilitation, length of stay, destination at discharge, and family caregiver. However, in multiple linear regression analyses, age, destination at discharge, family caregiver were not significant predictors. CONCLUSION: Age was not predictor of motor functional outcome and rehabilitation can be effective in elderly SCI patients. Rehabilitation intervention should begin as soon as possible. The admission motor FIM score, level and severity of injury, interval between onset and admission, anxiety/depression score, and length of stay can be used to predict functional outcomes of rehabilitation in SCI patients.

Determinants of health-related quality of life impairment in Egyptian children and adolescents with juvenile idiopathic arthritis: Sharkia Governorate.

The aim of this study was to identify the possible determinants of impaired health-related quality of life (HRQOL) in Egyptian children and adolescents with juvenile idiopathic arthritis (JIA). Fifty-eight consecutive patients of JIA aged from 8 to 18 years underwent assessment of socio-economic and demographic characteristics; HRQOL using Pediatric Quality of Life Inventory 4.0 Generic Core Scale, disease activity using the Juvenile Arthritis Disease Activity Score based on 27 joints (JADAS-27), functional ability using the childhood health assessment questionnaire (CHAQ), pain score on visual analog scale and psychological symptoms using the Children's Depression Inventory (CDI) score. Multivariate modeling was applied to determine the factors that associated with HRQOL impairment. A total of 55 % of the patients (32 of 58) had impaired HRQOL (<78.6). In multiple regression analyses, high CHAQ scores (OR 6.0, 95 % CI 2.0-17.5, P = 0.001), pain (OR 3.1, 95 % CI 1.9-6.3, P = 0.01), stop going to school (OR 3.9, 95 % CI 2.0-7.3, P = 0.01), low socioeconomic status (OR 2.3, 95 % CI 1.09-4.7, P = 0.04) and high psychological symptoms (OR 4.2, 95 % CI 2.0-12.6, P = 0.001) were determinants for HRQOL impairment. HRQOL impairment is a significant problem in Egyptian children and adolescents with JIA. These findings underscore the critical need for monitoring of HRQOL in these patients. More attention should be given to JIA patients who stop going to school and who has low socioeconomic status.

Predictors of functional outcome in Saudi Arabian patients with stroke after inpatient rehabilitation.

PURPOSE: To identify the possible factors influencing functional outcome of stroke patients after inpatient rehabilitation. METHODS: One hundred and eighty patients with stroke consecutively admitted for inpatient stroke rehabilitation was studied. Demographic and stroke characteristics, impairment (National Institutes of Health Stroke Scale), disability level (Functional Independence Measure [FIM]), psycho-emotional state (Geriatric Depression Scale-15 [GDS-15]), cognitive function (Mini Mental State Evaluation [MMSE]), and preexisting medical conditions were recorded at admission. The main measure of functional outcome was the discharge FIM score. The univariate and multiple linear regression analyses were performed. RESULT: The Mean admission total FIM score was 64.8 ± 22.4 and the mean discharge total FIM score was 84.0 ± 23.0, with this gain being highly significant (P < 0.001). Univariate analyses indicated that the significant factors influencing functional outcome of stroke patients at discharge from rehabilitation included age, total FIM score at admission, severity of stroke, recurrent stroke, cognitive impairment, and depression. However, in multiple linear regression analyses, age was not significant predictor. CONCLUSION: Age predicts the function outcome to lesser extent than other covariate. The admission total FIM score, cognitive condition, depression, and stroke severity are predictors of functional outcome of stroke patients after inpatient rehabilitation.
