Impacts of FcγRIIB and FcγRIIIA gene polymorphisms on systemic lupus erythematous disease activity index

Objective Systemic lupus erythematous (SLE) disease is a chronic autoimmune disease with unknown etiology that can involve different organs. Polymorphisms in Fcγ receptors have been identified as genetic factors in susceptibility to SLE. This study was aimed to investigate effects of two single nucleotide polymorphisms (SNPs) within FcγRIIB and FcγRIIIA genes on systemic lupus erythematous disease activity index (SLEDAI) in an Iranian population. Results Our findings indicated TT and GG genotypes were the common genotypes of FcγRIIB and FcγRIIIA SNPs in SLE patients, respectively. There were no significant differences in genotype and allele frequencies of FcγRIIB and FcγRIIIA SNPs in SLE and healthy subjects. However, the frequencies of genotypes and alleles of FcγRIIB and FcγRIIIA SNPs were significantly associated with some clinical manifestations used to determine SLEDAI (P < 0.001–0.5).

Metabolomics in Autoimmune Diseases: Focus on Rheumatoid Arthritis, Systemic Lupus Erythematous, and Multiple Sclerosis

The metabolomics approach represents the last downstream phenotype and is widely used in clinical studies and drug discovery. In this paper, we outline recent advances in the metabolomics research of autoimmune diseases (ADs) such as rheumatoid arthritis (RA), multiple sclerosis (MuS), and systemic lupus erythematosus (SLE). The newly discovered biomarkers and the metabolic mechanism studies for these ADs are described here. In addition, studies elucidating the metabolic mechanisms underlying these ADs are presented. Metabolomics has the potential to contribute to pharmacotherapy personalization; thus, we summarize the biomarker studies performed to predict the personalization of medicine and drug response.

Validity and reliability of patient reported outcomes measurement information system computerized adaptive tests in systemic lupus erythematous

Background The evaluation of Patient Reported Outcomes Measurement Information System (PROMIS) computerized adaptive test (CAT) in adults with systemic lupus erythematous (SLE) is an emerging field of research. We aimed to examine the test–retest reliability and construct validity of the PROMIS CAT in a Canadian cohort of patients with SLE. Methods Two hundred twenty-seven patients completed 14 domains of PROMIS CAT and seven legacy instruments during their clinical visits. Test–retest reliability of PROMIS was evaluated 7–10 days from baseline using intraclass correlation coefficient (ICC (2; 1)). The construct validity of the PROMIS CAT domains was evaluated against the commonly used legacy instruments, and also in comparison to disease activity and disease damage using Spearman correlations. A multitrait-multimethod matrix (MMM) approach was used to further assess construct validity comparing selected 10 domains of PROMIS and SF-36 domains. Results Moderate to excellent reliability was found for all domains (ICC [2;1] ranging from lowest, 0.66 for Sleep Disturbance and highest, 0.93 for the Mobility domain). Comparing seven legacy instruments with 14 domains of PROMIS CAT, moderate to strong correlations (0.51–0.91) were identified. The average time to complete all PROMIS CAT domains was 11.7 min. The MMM further established construct validity by showing moderate to strong correlations (0.55–0.87) between select PROMIS and SF-36 domains; the average correlations from similar traits (convergent validity) were significantly greater than the average correlations from different traits. Conclusions These results provide evidence on the reliability and validity of PROMIS CAT in SLE in a Canadian cohort.

Association of Parvovirus B19 with Rheumatic Diseases

Human parvovirus B19 infections are well reported to be associated with different autoimmune disorders. They can either mimic or trigger autoimmune diseases, such as systemic lupus erythematous (SLE), rheumatoid arthritis (RA), and vasculitis. A lack of awareness about this infection can result in delays in diagnosis and poor care. In this review, the basic biology and clinical aspects of the parvovirus, human immune response, and the pathogenesis in the rheumatic diseases are discussed.

P042 Profile of systemic lupus erythematous patients at presentation 10 years of Single center experience-Tripoli-Libya

Background Juvenile Systemic Lupus Erythematous (JSLE) is a systemic autoimmune disorder with speckled manifestations that can emerge overstretched period of time and can affect any organ system, most frequently the skin, joints, kidneys, and the nervous, hematologic, and cardiovascular systems. The Aim is to examine the clinical features, serologic and laboratory characteristics associated with SLE. To probe and outline Clinical and Immunologic features of Incomplete Lupus Erythematous (ILE) patients who progressed from ILE to SLE. Methods The files of patients diagnosed as SLE in pediatric rheumatology clinic from 2001 to 5/2021 were retrospectively reviewed. Result Thirty SLE cases were included; Females were more prevalent with a female: male ratio of 14:1. Mean age at presentation 11 ± 4 years (range of 5 months-13 years), Disease onset was before sixth birthday in (7%), above twelve years in (40%) of the patients, and 53% of the patients was among 6 –12 years age group (31% & 37% of them fulfilled the SLICC & ACR criteria respectively at diagnosis) .The Mean duration between the onset of symptoms and SLE diagnosis was 6 months ±2 years. The Pre-pubertal age group presented early. At diagnosis, 50% of the patient got SLICC score criteria &lt;4, on other hand 70% of the patients had ACR score criteria less than four Variable The most common presenting feature was arthritis (83%) (polyarticular arthritis) followed by dermatological manifestations (46%) photosensitivity, malar rash, and discoid rash in order of most frequent, fatigability (37%), renal manifestation (23%) most commonly as hematuria, one case diagnosed as lupus nephritis by renal biopsy. ANA was positive in 87%, anti-ds-DNA positive in 40% and Anti sm positive in 17%. The most frequently used medications were steroids and hydroxychlorqiune, the most commonly used steroid sparing medications were azathioprine (43%), Mycophenolate mofetil (40%) and ciclosporin (13%), 26% were on antihypertensive, 3% required rituximab to control their disease and one patient received Eltromboag to treat refractory thrombocytopenia. the mean follow-up duration 46.9 ± 43.6m, 20% lost follow up, 13% died due to disease complications (renal system involvement, thrombocytopenia and neurological system involvements). Conclusion jSLE in Libya is very rare before the sixth birthday and presented early among 6–12 years age group with a delay of less than one year between the first presentation and time of diagnosis. SLICC criteria was sufficient to diagnose the disease in &gt; 50% of patients. High index of suspension should be maintained because in some patient’s years may be passed before fulfilling the diagnostic criteria. The most common cause of death is renal involvement. Glucocorticoids are the backbone of jSLE treatment in the acute phase. Both azathioprine and Mycophenolate mofetil are sufficient to control the disease in most patients. The disease outcome is accepted in our cohort as most patients have mild disease activity with low dose steroid and a steroid-sparing agent.

Systemic lupus Erythematous as an Unusual Cause of Intussusception in Sudanese Woman: Case report

A middle-aged Sudanese woman has been presented complained about multiple joint pain, skin rash, chest pain, hair loss, severe abdominal pain associated with abdominal distension, bloody diarrhoea and vomiting. Lab investigation and computed tomography (CT) abdomen revealed the patient have an intussusception on top of SLE. The patient was treated
