Int J Womens Health 2024; 16:891-902. [PMID: 38779383 PMCID: PMC11110830 DOI: 10.2147/ijwh.s461640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Accepted: 05/11/2024] [Indexed: 05/25/2024] Open
Abstract
Introduction Previous studies have shown that pregnant women with systemic lupus erythematosus (SLE) tend to have a higher risk of adverse pregnancy outcomes, but the potential causal role remained unclear. In this study, we aimed to investigate the causal relationship between SLE and some common pregnancy complications and outcomes using two-sample Mendelian randomization (MR). Methods The genetic tools were derived from genome-wide association studies of SLE and pregnancy complications and outcomes. MR analysis was performed using inverse variance weighting as primary method. Sensitivity analyses were performed to evaluate the robustness of the results. A retrospective analysis was conducted on 200 pregnant women with SLE and a control group of pregnant women delivering at Tongji Hospital. Results In the results, we found that genetic susceptibility to SLE was associated with a higher risk of gestational diabetes mellitus (OR = 1.028, 95% CI: 1.006-1.050), premature delivery (OR = 1.039, 95% CI: 1.013-1.066), polyhydramnios (OR = 1.075, 95% CI: 1.004-1.151) and premature rupture of membranes (OR = 1.030, 95% CI: 1.001-1.060). Some of the retrospective analysis results align with the findings from the MR analysis, indicating that pregnant women with SLE have a higher risk of developing gestational diabetes mellitus and preterm birth. Additionally, although MR analysis did not reveal a causal relationship between SLE and preeclampsia/eclampsia, retrospective analysis discovered that SLE pregnant women are more susceptible to developing preeclampsia/eclampsia (OR = 2.935, 95% CI: 1.118-7.620). Conclusion Our study findings suggest a potential causal relationship between SLE and increased risks of gestational diabetes and preterm delivery. Clinical data indicate that pregnant women with SLE are more prone to developing preeclampsia/eclampsia. Clinicians need to be vigilant about the occurrence of these conditions when managing pregnant women with SLE.

Open Life Sci 2024; 19:20220812. [PMID: 38465338 PMCID: PMC10921503 DOI: 10.1515/biol-2022-0812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 11/16/2023] [Accepted: 11/16/2023] [Indexed: 03/12/2024] Open
Abstract
Henoch-Schönlein purpura (HSP) and pediatric-onset systemic lupus erythematosus (pSLE) are closely associated with vasculitis and vascular diseases. This study aimed to investigate the clinical diagnostic values of Ang-1, Ang-2, and Tie2 for HSP and pSLE. We surveyed 82 HSP patients, 34 pSLE patients, and 10 healthy children. The expression levels of Ang-1, Ang-2, and Tie2 in the serum and urine were assessed using enzyme-linked immunosorbent assay. The diagnostic values of Ang-1, Ang-2, and Tie2 for HSP and pSLE were evaluated using receiver operating characteristic curve analysis. The results revealed that the serum and urine expression levels of Ang-2 and Tie2 were significantly elevated in HSP and pSLE patients, whereas the Ang-1/Ang-2 values were reduced. Additionally, Ang-1 was highly expressed in the serum and urine of HSP patients and in the serum of pSLE patients. Ang-1, Ang-2, and Tie2 showed differential expression in various types of HSP and pSLE compared with their expression in healthy controls. In summary, Ang-1, Ang-2, and Tie2 can serve as biomarkers for HSP and pSLE. Moreover, Ang-1/Ang-2 values are reduced in HSP and pSLE patients. Ang-1, Ang-2, and Tie2 can be used as biomarkers for HSP and pSLE.

Abstract
Childhood-onset systemic lupus erythematosus is a rare disease that is more prevalent in Southeast Asian children than in Western children. It is characterised by a peripubertal onset and a female predominance that rises with age. Haematological, renal, and mucocutaneous are among the frequently involved organs upon diagnosis. Some of the typical symptoms include cutaneous vasculitis, malar rash, and fever. Patients frequently had proliferative class IV lupus nephritis, which increases disease activity and kidney damage. We reported a child presented with fever associated with multiple joint pain, skin rashes over the fingers of the right hand, and generalised abdominal pain.

Anti-Inflammatory and Immunomodulatory Effect of High-Dose Immunoglobulins in Children: From Approved Indications to Off-Label Use. Cells 2023; 12:2417. [PMID: 37830631 PMCID: PMC10572613 DOI: 10.3390/cells12192417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 09/23/2023] [Accepted: 10/05/2023] [Indexed: 10/14/2023] Open
Abstract
BACKGROUND The large-scale utilization of immunoglobulins in patients with inborn errors of immunity (IEIs) since 1952 prompted the discovery of their key role at high doses as immunomodulatory and anti-inflammatory therapy, in the treatment of IEI-related immune dysregulation disorders, according to labelled and off-label indications. Recent years have been dominated by a progressive imbalance between the gradual but constant increase in the use of immunoglobulins and their availability, exacerbated by the SARS-CoV-2 pandemic. OBJECTIVES To provide pragmatic indications for a need-based application of high-dose immunoglobulins in the pediatric context. SOURCES A literature search was performed using PubMed, from inception until 1st August 2023, including the following keywords: anti-inflammatory; children; high dose gammaglobulin; high dose immunoglobulin; immune dysregulation; immunomodulation; immunomodulatory; inflammation; intravenous gammaglobulin; intravenous immunoglobulin; off-label; pediatric; subcutaneous gammaglobulin; subcutaneous immunoglobulin. All article types were considered. IMPLICATIONS In the light of the current imbalance between gammaglobulins' demand and availability, this review advocates the urgency of a more conscious utilization of this medical product, giving indications about benefits, risks, cost-effectiveness, and administration routes of high-dose immunoglobulins in children with hematologic, neurologic, and inflammatory immune dysregulation disorders, prompting further research towards a responsible employment of gammaglobulins and improving the therapeutical decisional process.

Abstract
OBJECTIVE Clinical evaluation of systemic lupus erythematosus (SLE) disease activity is limited and inconsistent, and high disease activity significantly, seriously impacts on SLE patients. This study aims to generate a machine learning model to identify SLE patients with high disease activity. METHOD A total of 1014 SLE patients with low disease activity and 453 SLE patients with high disease activity were included. A total of 94 clinical, laboratory data and 17 meteorological indicators were collected. After data preprocessing, we use mutual information and multisurf to evaluate and select the importance of features. The selected features are used for machine learning modeling. Performance of the model is evaluated and verified by a series of binary classification indicators. RESULTS We screened out hematuria, proteinuria, pyuria, low complement, precipitation, sunlight and other features for model construction by integrated feature selection. After hyperparameter optimization, the LGB has the best performance (ROC: AUC = 0.930; PRC: AUC = 0.911, APS = 0.913; balance accuracy: 0.856), and the worst is the naive bayes (ROC: AUC = 0.849; PRC: AUC = 0.719, APS = 0.714; balance accuracy: 0.705). Finally, the selection of features has good consistency in the composite feature importance bar plot. CONCLUSION We identify SLE patients with high disease activity by a simple machine learning pipeline, especially the LGB model based on the characteristics of proteinuria, hematuria, pyuria and other feathers screened out by collective feature selection.

Abstract
Pediatric mixed connective tissue disease (MCTD) is a subgroup of overlap syndromes. We aimed to compare the characteristics and outcomes in children with MCTD and other overlap syndromes. All MCTD patients met either Kasukawa or Alarcon-Segovia and Villareal criteria. The patients with other overlap syndromes had the features of ≥ 2 autoimmune rheumatic diseases but did not meet MCTD diagnostic criteria. Thirty MCTD (F/M = 28/2) and thirty (F/M = 29/1) overlap patients were included (disease onset < 18 years). The most prominent phenotype at disease onset and the last visit was systemic lupus erythematosus (SLE) in the MCTD group; juvenile idiopathic arthritis and dermatomyositis/polymyositis, respectively, in the overlap group. At the last visit, systemic sclerosis (SSc) phenotype was more frequent among MCTD than overlap patients (60% vs. 33.3%; p = 0.038). The frequency of the predominant SLE phenotype had decreased (60% to 36.7%), while predominant SSc phenotype had increased (13.3% to 33.3%) during follow-up in MCTD patients. Weight loss (36.7% vs. 13.3%), digital ulcers (20% vs. 0), swollen hands (60% vs. 20%), Raynaud phenomenon (86.7% vs. 46.7%), hematologic involvement (70% vs. 26.7%), and anti-Sm positivity (29% vs. 3.3%) were more common, while Gottron papules (16.7% vs. 40%) were less frequent among MCTD than overlap patients (p < 0.05). A higher percentage of overlap patients achieved complete remission than MCTD patients (51.7% vs. 24.1%; p = 0.047). The disease phenotype and outcome differ between pediatric MCTD and other overlap syndromes where MCTD may be regarded as a more severe disease. Analyzing these patients could pave the way for early and effective treatment.

Abstract
We report the cases of two children who presented with autoimmune hemolytic anemia (AIHA) as an initial presentation of systemic lupus erythematosus (SLE). Both patients had a positive Coombs test, anemia, and an increased number of spherocytes in their blood smear. The patient in Case 1 presented with fever, urticarial erythema, facial paresis, AIHA, and leucopenia. Immunological screening revealed low complement protein levels and positive anti-nuclear antibody, anti-double-stranded DNA, and antiphospholipid antibody results. A further laboratory workup revealed a positive lupus anticoagulant (LA) result and low factor II levels. She was diagnosed with lupus anticoagulant hypoprothrombinemia syndrome (LAHPS) in addition to SLE. The patient in Case 2 presented with fever, butterfly rash, thyroid enlargement, leucopenia, and AIHA. She was diagnosed with SLE with thyroiditis. Both patients were started on combined immunosuppressive therapy, and both patients’ clinical symptoms finally resolved. A literature review on childhood SLE showed that AIHA is common in patients with SLE. LAHPS is an uncommonly identified cause of bleeding in patients with SLE, and it must be considered when evaluating children with a positive LA result.

Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune inflammatory disease that predominantly affects women of childbearing age and results in various adverse pregnancy outcomes (APOs). Pregnancy was formerly discouraged in patients with SLE because of unstable disease activity during the gestation period, increased thrombosis risk, severe organ damage, and inevitable side effects of immunosuppressive agents. Currently, most patients with SLE have successful pregnancies due to preconception counselling, strict monitoring, and improved therapy with minimised complications for both the mother and foetus. Hydroxychloroquine (HCQ) is extensively used and is beneficial for improving pregnancy outcomes. However, pregnant women with SLE have a high-risk of APOs, such as disease flare, preterm birth, intrauterine growth restriction (IUGR), preeclampsia, and pregnancy loss. Better understanding of the changes in maternal immunity and serum biomarkers, as well as their relationships with SLE-related APOs progression, would facilitate the investigation of molecular mechanisms for triggering and ameliorating APOs. Furthermore, it would enable us to explore and develop novel and effective therapeutic strategies to prevent disease activation. Therefore, this review briefly introduces the interaction between pregnancy outcomes and SLE, elucidates pathophysiological and immunological changes during SLE pregnancy. Furthermore, this review systematically expounds on the effective predictors of APOs and the molecular mechanisms underlying the SLE-related APOs to provide a solid foundation for the advanced management of lupus pregnancy.

Abstract
Objective Anemia is common in patients with juvenile systemic lupus erythematosus (jSLE). While autoimmune hemolytic anemia (AIHA) is the only etiology included in the classification criteria, the etiology of anemia in jSLE may be diverse. We aimed to investigate the etiology of anemia in jSLE and the relationship between anemia and disease characteristics at onset and during the follow-up period. Methods Patients diagnosed with jSLE who met the Systemic Lupus Erythematosus International Collaborating Clinics classification criteria between January 2012 and December 2020 were retrospectively analyzed. Results Hematologic involvement was observed in 70% of the patients. Anemia was the most common cytopenia among patients (60%). Anemia of chronic disease (ACD) and AIHA were the most common etiological factors, both observed in 23% of patients. Patients with anemia had a significantly higher rate of positive ds-DNA antibody and higher erythrocyte sedimentation rate (ESH) and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) scores. ESH, serum ferritin, and SLEDAI scores negatively correlated with hemoglobin levels in patients with anemia. Iron deficiency was the sole etiology of new-onset anemia. Patients with new-onset anemia during the follow-up period had significantly lower hemoglobin values at onset and a higher rate of renal involvement. Conclusion Anemia in jSLE is mostly AIHA and ACD, but iron deficiency is not rare. The severity of inflammation is associated with the severity of anemia. During the follow-up period, iron deficiency was the predominant cause of anemia, especially in patients with lower hemoglobin concentrations at onset and renal involvement.
