Abstract
Background This study aims to evaluate the immunological features of gastrointestinal (GI) bleeding in children with Henoch-Schönlein purpura (HSP). Study Design This retrospective study was conducted on children with HSP. Demographic and clinical data were collected, including serum immunoglobulin (Ig) levels, complement C3 and C4 levels, and lymphocyte subtype percentage. Results A total of 446 hospitalized children had HSP. Eighty-six children with HSP had GI bleeding, 114 had proteinuria, and 107 had hematuria. Lower arthralgia, prolonged glucocorticoid use, increased white blood cell counts, elevated neutrophils and neutrophil-to-lymphocyte ratio, reduced IgG and C3 levels, elevated CD19+ cell percentage, and reduced CD3+ cell and natural killer cell percentages were associated with GI bleeding risk in patients with HSP. Multivariate regression analysis revealed that arthralgia, glucocorticoid use, increased neutrophil percentage, reduced IgG and C3 levels, and increased CD19+ cell percentage were independent predictors of GI bleeding. Further analysis indicated that the combination of C3 and CD19+ cell percentages had a high predictive ability for GI bleeding in children with HSP. Conclusion This study indicated that reduced C3 and increased CD19+ cell percentages contributed to the development of GI bleeding in children with HSP. Specific immunologic profiles may be strongly correlated with GI bleeding risk in children with HSP.

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.

Can Respir J 2023; 2023:5607473. [PMID: 37020746 PMCID: PMC10070020 DOI: 10.1155/2023/5607473] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 01/29/2023] [Accepted: 03/05/2023] [Indexed: 03/30/2023] Open
Abstract
Background. There is no radiological measurement to estimate the severity of pediatrics juvenile dermatomyositis (JDM) with interstitial lung disease (ILD). We validated the effectiveness of CT scoring assessment in JDM patients with ILD. Aim. To establish a CT scoring system and calculate CT scores in JDM patients with ILD and to determine its reliability and the correlation with Krebs von den Lungen-6 (KL-6). Methods. The study totally enrolled 46 JDM-ILD patients and 16 JDM without ILD (non-ILD, NILD) patients. The chest CT images (7.0 ± 3.6 years; 32 male and 30 female) were all analyzed. CT scores of six lung zones were retrospectively calculated, included image pattern score and distribution range score. Image pattern score was defined as follows: increased broncho-vascular bundle (1 point); ground glass opacity (GGO) (2 points); consolidation (3 points); GGO with bronchiectasis (4 points); consolidation with bronchiectasis (5 points); and honeycomb lung (6 points). Distribution range score was defined as no infiltrate (0 point); <30% (1 point); 30%–60% (2 points); and ≥60% (3 points). Two pediatric radiologists reviewed all CT images independently. The ROC curve was established, and the optimal cutoff score for severity discrimination was set. Results. The agreement between two observers was excellent, and the ICC was 0.930 (95% CI 0.882–0.959,
). CT score and KL-6 level had a positive linear correlation (r = 0.784,
). However, the correlation between CT scores of different lung zone and KL-6 level was different. The KL-6 cut off level suggested for JDM with ILD was 209.0 U/ml, with 73.9% sensitivity and 87.5% specificity, and the area under curve was (AUC) 0.864 (
). Conclusion. The CT scoring system we established, as a semiquantitative method, can effectively evaluate ILD in JDM-PM patients and provide reliable evidence for treatment.
