thrombocytopenia SLE

Noonan syndrome (NS) is a dominantly inherited genetic disorder with mutations in genes encoding components or regulators of the RAS/mitogen-activated protein kinase pathway. Its diagnosis is based on characteristic features, including typical facial features, a short stature, congenital heart disease, mild developmental delay, and cryptorchidism. Patients with NS sometimes develop autoimmune diseases, such as Hashimoto's thyroiditis and, rarely, systemic lupus erythematosus (SLE). We herein present a 29-year-old Japanese female with NS complicated by SLE and repeated severe hypoglycemia...

BACKGROUND: Thrombocytopenia ranges from 20% to 40% in patients with systemic lupus erythematosus (SLE). It is usually associated with severe disease manifestations and worse disease outcomes. AIM OF THE STUDY: To identify the frequency of thrombocytopenia in a cohort of Egyptian patients with SLE and to examine the relationship of thrombocytopenia with various disease manifestations and disease outcomes. METHODS: Data on 902 SLE patients were collected, including demographics, clinical, laboratory, immunological findings, and medications...

OBJECTIVE: The annual hospitalization rate of patients with systemic lupus erythematosus (SLE) is approximately 10%, and hospitalizations are responsible for most of the healthcare expenses. Herein, we analyzed 5-year hospitalization data of SLE patients and determined factors leading to hospitalization. METHODS: Clinical, laboratory, and hospitalization data of SLE patients admitted to our rheumatology clinic in 2015-2020 were retrieved from our SLE database and analyzed...

Systemic lupus erythematosus (SLE) is an autoimmune disease that can cause various health problems, including issues with the blood. One common blood-related symptom in SLE is immune thrombocytopenia (ITP), which leads to low platelet counts. In some cases, SLE patients with ITP may develop a rare but serious complication called subdural hematoma (SDH), which is a type of bleeding in the brain. This combination of conditions can be challenging to manage and has a high mortality rate. In a specific case, a 14-year-old girl with chronic ITP developed a sudden headache and was diagnosed with childhood-onset SLE, leading to the development of SDH...

IgG4-related disease (IgG4-RD) is a systemic condition in which IgG4+ plasma cell infiltration and fibrosis cause organ swelling and lead to diverse clinical manifestations. Although IgG4-RD typically responds to glucocorticoids (GCs), relapse during tapering occurs and an early GC-sparing approach might therefore be beneficial. Systemic lupus erythematosus (SLE) is a chronic inflammatory disease with multiple symptoms that is also treated with GCs as a first-line therapy. Recently, belimumab, a recombinant human IgG-1λ monoclonal antibody that inhibits B-cell activating factor, was approved, but reports of use for IgG4-RD are scarce...

STUDY OBJECTIVE: This study aims to investigate the characteristics of patients with an initial diagnosis of systemic lupus erythematosus (SLE) in an emergency department (ED) and their outcomes. METHODS: A total of 147 SLE patients (119 females and 28 males, mean age 26 ± 19 years) who visited the ED of the Peking University People's Hospital between January 2017 and June 2022 were enrolled in the study. Data on demographic information, clinical characteristics, comorbidities, therapy, and outcomes were collected...

Immune thrombocytopenia (ITP) has been comprehensively studied and understood in Western Europe and various Asia-Pacific regions. However, the epidemiological and clinical-laboratory aspects of ITP in Malaysia remain limited and not well documented. Therefore, this study aims to evaluate the incidence and clinical parameters of ITP using 20-year retrospective data. Medical records for 205 consecutive adult patients with ITP between January 2000 and December 2022 were analyzed. A p-value of <0.05 is considered statistically significant...

METHODS: It is an observational cohort study with analysis of the baseline database of the INSPIRE cohort with early outcomes assessed till April 10, 2023. Cases with GI manifestations as per the BILAG index were selected, pertinent clinical and laboratory data were retrieved for analysis. Patients with GI manifestations were compared with the rest of the cohort and factors associated with death were determined...

Thrombocytopenia is a common manifestation associated with the presence of antiphospholipid antibodies (aPL). The aim of this study is to investigate the efficacy and safety of tacrolimus treatment in aPL associated thrombocytopenia. This is a single-center retrospective study. Patients who had persistent positive aPL and thrombocytopenia that was treated with tacrolimus were included. A total of 49 patients [38 females (77.6%)] were enrolled from Nov 2013 to Apr 2022 with a median treatment duration of 22 months...

If one had any doubts before the pandemic regarding the correlation between infections and autoimmunity, COVID-19 left us fascinated on the strong bond between the two entities. The immune and autoimmune reactions seen in patients infected with SARS-CoV-2 have served as a base for this assumption. Later on, the use of immunosuppressants such as systemic glucocorticoids, among other biological agents, turned this assumption to a fact. This was no different when it comes to the vaccines against COVID-19. Through several postulated mechanisms these vaccines, although generally considered safe, are thought to have the potential to result in autoimmune reactions making them not more innocent than the infection itself...

Background Platelet transfusion is a life-saving procedure for thrombocytopenic patients. Platelet transfusions can be either prophylactic or therapeutic. Prophylactic platelet transfusion reduces the risk of bleeding before any specific procedure, whereas therapeutic platelet transfusion helps to control active bleeding. Evaluation of the response to platelet transfusion by calculating the corrected count increment (CCI) is important to determine the success of platelet transfusion and to plan subsequent patient management...

INTRODUCTION: Microvascular manifestations constitute a subtype of antiphospholipid syndrome, and those patients have relatively poor prognoses, so it is important to find markers for microvascular manifestations. This study was conducted to explore whether serum calprotectin could be a predictor of microvascular manifestations in antiphospholipid antibody (aPL)-positive patients. METHODS: Consecutive patients with persistent aPL positivity referred to Peking Union Medical College Hospital and age- and sex-matched health controls (HCs) were included...

Thrombocytopenia can be one of the first manifestations of systemic lupus erythematosus and occurs in up to 40% of patients. Additionally, approximately 2% of patients with primary immune thrombocytopenia may develop systemic lupus erythematosus. Systemic lupus erythematosus is a highly heterogeneous disease, and in some patients, it may present mainly with hematological findings. Thrombocytopenia associated with systemic lupus erythematosus is also diverse, ranging from asymptomatic to severe, acute, or chronic cases...

Regulatory T (Treg) cells are essential for maintaining self-immune tolerance. Reduced numbers or functions of Treg cells have been involved in the pathogenesis of various autoimmune diseases and allograft rejection. Therefore, the approaches that increase the pool or suppressive function of Treg cells in vivo could be a general strategy to treat different autoimmune diseases and allograft rejection. Interleukin-2 (IL-2) is essential for the development, survival, maintenance, and function of Treg cells, constitutively expressing the high-affinity receptor of IL-2 and sensitive response to IL-2 in vivo ...

AIM: We investigated the diagnostic utility of serum YKL-40 in patients with SLE and examined its correlation with disease activity. Additionally, we examined any differences in serum YKL-40 levels between juvenile and adult SLE patients. METHODS: We included 78 female patients with SLE and 42 controls...

UNLABELLED: This study aims to analyze the clinical characteristics and risk factors of high-risk groups of neonatal lupus erythematosus (NLE) in term infants. High-risk groups of NLE infants whose mothers were positive for anti-SSA, anti-SSB or anti-U1RNP antibodies during pregnancy were enrolled. They were born between February 2013 and February 2020, with a gestational age not less than 37 weeks. We analyzed their clinical data from birth to 24 months after birth. A total of 105 patients in the NLE high-risk group were included...

BACKGROUND: Pregnancy in SLE continues to be a challenge. The neutrophil-to-lymphocyte ratio (NLR) and chemerin are predictors of preeclampsia in the general population; however, their role as predictors of maternal-fetal complications in pregnant SLE patients has not been analyzed. OBJECTIVE: To investigate the prognostic value of NLR and serum chemerin, to predict maternal-fetal complications in pregnant SLE patients, and compare both biomarkers among three study groups...

The overlap of rheumatoid arthritis and systemic lupus erythematosus is well described, with a syndrome known as 'rhupus'. ANCA-associated vasculitis, however, is uncommonly associated with other autoimmune conditions. Here we present a case of lupus, rheumatoid arthritis, and ANCA-associated vasculitis, with significant time elapsed between presentations, resulting in an accumulation of the three diagnoses over the course of 35 years. The patient was diagnosed with lupus at age 45, presenting with inflammatory polyarthritis, thrombocytopenia, leukopenia, positive ANA, positive anti-DNA, and hypocomplementemia...

We aimed to characterize the genetic basis of disease in a family with multiple autoimmune manifestations, including systemic lupus erythematosus (SLE), immune thrombocytopenia, and autoimmune thyroiditis. Whole exome sequencing (WES) was conducted to identify candidate variants, which were analyzed by flow cytometry, immunoblotting, immunoprecipitation, and luciferase reporter assay in transfected 293T cells. Gene expression in peripheral blood mononuclear cells (PBMC) was profiled by bulk RNA sequencing and plasma cytokines were measured by proximity extension assay...
