The burden of entheseal involvement in systemic lupus erythematosus: a comparative ultrasonograghic study.

Background: Imaging is crucial for identifying and diagnosis of the musculoskeletal (MSK) symptoms, which are one of the most typical manifestations of systemic lupus erythematosus (SLE). For the joints, tendons, and entheseal sites, ultrasonography has shown to be sensitive and accurate for the diagnosis of both inflammation and structural damage.

Aim: The goal of the current investigation is to determine the prevalence and the distribution of entheseal abnormalities in SLE patients, using musculoskeletal ultrasonography (MSUS) and to assess the relationship between entheseal sonographic changes and the SLE disease activity.

Significance of platelets to lymphocytes and platelets to haemoglobin ratios in patients with systemic sclerosis.

Background: Systemic sclerosis (SSc) is a progressive autoimmune connective tissue disease. Platelets to lymphocytes (PLR) and platelets to haemoglobin ratios (PHR) are emerging biomarkers used in the assessment of activity and severity of various autoimmune diseases. This study was designed to clarify the association of PLR and PHR with SSc disease activity and its different manifestations.

Validity and reliability of the Arabic version of the Self-Efficacy for Managing Chronic Disease scale in rheumatoid arthritis patients.

Background And Objectives: Rheumatoid arthritis (RA) is an autoimmune inflammatory condition that causing disability and affection of patient's quality of life (QoL). Self-efficacy investigation helps us to detect the requirements of chronically affected patients and evaluation of self-care management programs. The aim of our study was to test validity and reliability of Self-Efficacy for Managing Chronic Disease (SEMCD-Arabic) in RA patients.

Cultural adaptation and validation of the Systemic Sclerosis Quality of Life questionnaire into Arabic language.

Background And Objectives: Systemic sclerosis (SSc) is a chronic connective tissue disease affecting all quality of life (QoL) parameters. In addition to clinical assessment, QoL measures should be included in patient assessment. There is no Arabic tool specific for assessing QoL in Arabic SSc patients; therefore, this work was designed to translate the SScQoL questionnaire, culturally adapt and check its reliability and validity.
