SDF-1(CXCL12) polymorphisms in Egyptian patients with systemic lupus erythematosus (SLE): a pilot study

Abstract SDF-1(CXCL12) is a chemokine that plays an important role in the regulation of migration, proliferation, and differentiation of hematopoietic cells, as well as being involved in the homeostatic and inflammatory traffic of leukocytes. It was suggested that CXCL12 is a key molecule in the development of autoimmunity in the murine model of lupus. It has been demonstrated that SDF-1 has a G801A transition at position 801 in the 3′-untranslated region of the transcript, known as SDF-1-3′G801A. This polymorphism may have an important regulatory function via an increase in the biosynthesis of SDF-1 protein and has been reported in association with autoimmune diseases, such as type 1 diabetes and systemic sclerosis. We investigated the prevalence of SDF-1-3′G801A genotype in Egyptian patients with systemic lupus erythematosus (SLE) (n = 50) and healthy controls (HC) (n = 50) and its relation to SLE manifestations. We found a significant correlation between the SDF-1-3′G801A genotype and the following SLE features: photosensitivity, nephritis, serositis, and vasculitis, and also anticardiolipin antibodies. Our observations suggest that the SDF-1-3′-G801A genotype may be associated with some clinical and laboratory manifestations in patients with SLE.

This study assessed the effect of residual pain, age, sex, diabetes, hypertension, and depression on changes and status at one-year following arthroplasty with respect to shoulder function and overall physical and mental health status. Methods: A retrospective analysis of a prospective cohort of 140 patients tested preoperatively and one-year following shoulder arthroplasty was conducted at our tertiary hospital. Pearson's correlations and multiple regression analysis were performed to test the impact of predictors on shoulder pain and function assessed using the American Shoulder and Elbow Surgery (ASES) questionnaire...

Authors: Shah AS, Kalish LA, Bae DS, Peljovich AE, Cornwall R, Bauer AS, Waters PM, Treatment and Outcomes of Brachial Plexus Injuries (TOBI) Study Group Abstract Background: Microsurgical reconstruction is indicated for infants with brachial plexus birth palsy (BPBP) that demonstrate limited spontaneous neurological recovery. This investigation defines the demographic, perinatal, and physical examination characteristics leading to microsurgical reconstruction. Methods: Infants enrolled in a prospective multicenter investigation of BPBP were evaluated. Microsurgery was performed at the discretion of the treatin...

Authors: Levine B, Caccavallo P, Springer B, Meneghini RM Abstract In the current healthcare environment, the postoperative treatment of patients who undergo total knee arthroplasty (TKA) is critical to successful outcomes, patient satisfaction, and controlling costs. Preemptive analgesia and the avoidance of excessive narcotics may help improve the outcomes and satisfaction of patients who undergo TKA because it allows for a more rapid rehabilitation program and reduces overall pain. Various techniques can be used to minimize the postoperative pain routinely observed in these patients. In addition, appropriate pos...

CONCLUSIONS: Prevalence of select lifestyle risk behaviors exceeds 50% in adults with stroke but is higher in adults with diabetes compared with adults without diabetes. Effective interventions, community programs, and healthcare policy are needed to promote lifestyle management in adults with stroke, particularly among those with diabetes.

The objectives of this review are to outline results of the main recent therapeutic studies for SNV, which have led to establishment of current treatment strategies and significant improvement in patients' outcomes, and to describe knowledge gaps that current research hopes to bridge. Expert opinion: Therapy is mainly dictated by diagnosis, disease extent, and severity. In ANCA-associated vasculitis, an initial induction phase consists of tapering glucocorticoids combined with specific immunosuppressants. Maintenance therapy begins after 3 to 6 months, once all evidence of active disease has resolved, and can require years...

Authors: Wang P, Mao YM, Liu LN, Zhao CN, Li XM, Pan HF Abstract A growing body of data suggests that semaphorins are involved in both normal and pathological immune responses, as well as autoimmune pathologies. To investigate the plasma semaphorin 3A (Sema3A) and semaphorin 7A (Sema7A) levels in systemic lupus erythematosus (SLE) patients and their correlation with clinical manifestations and laboratory indexes, a two-step method was applied. First, 80 SLE patients and 80 healthy controls were recruited for comparing serum Sema3A and Sema7A concentrations. Second, 40 rheumatoid arthritis (RA) patients and 40 sj&ou...

Since 2012 the New Zealand public health sector has achieved 90% CVD risk assessment (CVDRA) for each eligible person across New Zealand using a modified version of an overseas risk equation, through incentivising Primary Health Organisation (PHO) performance. In 2018 the New Zealand Ministry of Health endorsed the use of a suite of four new CVDRA equations which were developed using t...
