Objective: To study the clinical features and laboratory parameters of neonatal lupus erythematosus (NLE) from India. Patients and methods: We analyzed case records of children diagnosed with NLE in the Pediatric Rheumatology Clinic at tertiary care centre from North India during the period January 1999 - December 2023. Results: Twenty-four babies are diagnosed with NLE during the study period. Median age at diagnosis was 60 days with a female predisposition (Male to female- 1:2). Cutaneous manifestations were reported in 14 (58%) patients. Hepatomegaly was noted in 15 (62.5%), and splenomegaly in 2 (8%). Elevated transaminases were noted in 14 (58%) patients, and cholestatic jaundice in one. Hematological manifestations were noticed in 20 (83.3%), and neurological manifestations were noticed in 8 patients. Most non-cardiac manifestations were self-limiting. Intravenous immunoglobulin was used for phrenic nerve palsy and autoimmune hemolytic anemia. Oral corticosteroid was used in a patient with refractory cytopenia, and four patients required transfusions. Cardiac involvement was reported in 13 (54%) patients – 3rd-degree heart block in 9 patients, and 6 were managed with epicardial pacemaker insertion. One patient required pacemaker reimplantation due to infective endocarditis. Congenital hydrops was seen in 3 patients, and required respiratory support and recovery was uneventful. Conclusion: NLE is associated with significant morbidity. More than half had cardiac manifestation, of which 70% had 3rd-degree heart block requiring pacemaker insertion. Other rare clinical manifestations like phrenic nerve palsy and seizures are noticed in our cohort. [ABSTRACT FROM AUTHOR]

The article presents a 4-year-old patient with unexplained cytopenias, ultimately diagnosed with extrahepatic portal vein obstruction (EHPVO), emphasizing its rare presentation and management. Topics discussed include hypersplenism as a cause of cytopenias, the diagnostic process for portal hypertension, and multidisciplinary approaches to managing EHPVO in children.

Myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) are heterogeneous neoplasms of hematopoietic stem cells that are challenging to diagnose, differentiate, and prognosticate. Cytogenetic and mutational analyses are useful in humans but unavailable for dogs, where diagnosis and classification still rely largely on hematologic and morphologic assessment. The objectives of this study were to apply a classification scheme to myeloid neoplasms and to assess outcome in relation to predictor variables. Keyword search of a laboratory database, application of sequential exclusion criteria, and consensus from 3 reviewers yielded 70 cases of myeloid neoplasia with hematology results, and cytologic (11), histologic (14), or both (45) types of marrow specimens. Based on blast percentage and morphology, 42 cases were classified as MDS and 28 as AML. Dogs with MDS had significantly lower body weights, hemoglobin concentrations and blood blasts, and higher red blood cell size variability and platelet numbers than dogs with AML. Estimates of median survival using Kaplan-Meier curves for dogs with MDS and AML were 384 and 6 days, respectively (P <.001). The instantaneous risk of death for dogs with MDS was approximately 5× lower than that of dogs with AML. Significant predictor variables of survival were body weight, white blood cell count, platelet count, and percent blood blasts (P <.05). Hazard ratios (HRs) derived from best-fitting Cox regression models were 1.043, 0.998, and 1.061 for increased neutrophils, decreased platelets, and increased blood blasts, respectively. Findings from this study suggest that hematologic and morphologic variables are useful to predict outcomes in myeloid neoplasia. [ABSTRACT FROM AUTHOR]

We investigated immune cytopenia in multiple myeloma (MM) patients with concurrent acquired aplastic anemia (AA), focusing on three clinical cases treated with plasma cell-directed therapy. All three patients achieved partial response in MM and one patient experienced complete resolution of AA. Two patients had partial improvement in transfusion requirement but continued to suffer from severe AA, leading to immunosuppressive therapy (IST) with improvement of transfusion requirement in both patients. In vitro serum testing of these patients demonstrated platelet mitochondrial dysfunction and platelet apoptosis but did not show sera-specific inhibition of erythroid colony formation in progenitor cells. The levels of IL8 and IL15 were elevated in MM patients with AA, implicating their potential roles in this co-occurrence. Response to IST points to the possibility of myeloma-dysregulated immune system leading to autoreactive T-cell destruction of hematopoietic stem and progenitor cells, offering insights for developing new treatment for cytopenia in MM.

Background: Ruxolitinib (RUX) is a JAK1/2 inhibitor approved for the therapy of myelofibrosis (MF) based on clinical trials including only intermediate2‐high risk (INT2/HIGH) patients. However, RUX is commonly used in intermediate‐1 (INT1) patients, with scarce information on responses and outcome. Methods: The authors investigated the benefit of RUX in 1055 MF patients, included in the "RUX‐MF" retrospective study. Results: At baseline (BL), 595 (56.2%) patients were at INT1‐risk according to DIPSS (PMF) or MYSEC‐PM (SMF). The spleen was palpable at <5 cm, between 5 and 10 cm, and >10 cm below costal margin in 5.9%, 47.4%, and 39.7% of patients, respectively; 300 (54.1%) were highly symptomatic (total symptom score ≥20). High‐molecular‐risk (HMR) mutations (IDH1/2, ASXL‐1, SRSF2, EZH2, U2AF1Q157) were detected in 77/167 patients. A total of 101 (19.2%) patients had ≥1 cytopenia (Hb < 10 g/dL: n.36; PLT <100 x 109/L: n = 43; white blood cells <4 x 109/L: n = 40). After 6 months on RUX, IWG‐MRT–defined spleen and symptoms response rates were 26.8% and 67.9%, respectively. In univariate analysis, predictors of SR at 6 months were no HMR mutations odds ratio [OR], 2.0, p =.05], no cytopenia (OR, 2.10; p =.01), and blasts <1% (OR, 1.91; p =.01). In multivariate analysis, absence of HMR maintained a significant association (OR, 2.1 [1.12–3.76]; p =.01). Conclusions: In INT1 patients, responses were more frequent and durable, whereas toxicity rates were lower compared to INT2/high‐risk patients. Presence of HMR mutations, cytopenia, and peripheral blasts identified less‐responsive INT1 patients, who may benefit for alternative therapeutic strategies. Overall survival and event‐free survival rates are significantly superior, whereas rate of ruxolitinib discontinuations is significantly lower in intermediate‐1 patients, confirming the benefits of ruxolitinib in patients with less advanced disease.

ABSTRACT Introduction Methods Results Conclusion The first‐step in diagnosis of myelodysplastic neoplasms (MDS) is essentially based on bone marrow cytomorphology. However, cytomorphology of MDS is often a difficult exercise, subject to inter‐operator variability. Our study aims to evaluate whether the combination of two dysplasia scores, the extended Ogata score and the MDS‐CBC score, could improve the screening of MDS patients among patients with chronic cytopenia.Extended Ogata score and MDS‐CBC score have been measured on a retrospective cohort of 63 patients with a clinical suspicion of MDS based on the presence of cytopenia. Among these patients, 33 patients were diagnosed as MDS (MDS group) and 30 patients were diagnosed with another cause of cytopenia (non‐MDS cytopenic control group).Our results show excellent performance of the combined scores in predicting MDS when the two scores are concordant: positive predictive value (PPV) = 96% and negative predictive value (NPV) = 92%. In comparison, in the same cohort, extended Ogata score alone showed a PPV = 90% and NPV = 79%, MDS‐CBC score alone showed a PPV = 85% and NPV = 86%.For the first time, our results show that the combination of these two dysplasia scores constitutes a useful and rapid tool for the assessment of dysplasia associated with MDS. In the MDS diagnostic process, the use of combined scores could constitute a valuable tool to enable early strong prediction of MDS in cytopenic patients and to target patients who initially require additional genetic assays.

SARS coronavirus (SARS-CoV-2) since the year 2020 has been affecting people of all age groups involving all systems possible. The effect of COVID-19 on hematological system has been commonly seen in the form of cytopenia, prothrombotic states, or disorders of coagulation, but it has been rarely implicated as a causal factor for hemolytic anemia in children. We present a 12-year-old male child who presented in congestive cardiac failure due to severe hemolytic anemia caused by SARS-CoV-2, with hemoglobin falling to a nadir of 1.8 g/dL. Child was diagnosed as a case of autoimmune hemolytic anemia and managed with supportive management and long-term steroids. This case highlights one of the lesser known effects of the virus, causing severe hemolysis and the role of steroids in its treatment. [ABSTRACT FROM AUTHOR]

Objectives We attempt to analyze bone marrow findings and correlation with cytopenia(s) after anti–B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell infusion in this study. Methods Relevant clinicopathologic data, including complete blood counts, neutrophil counts, relevant therapy history, and pre- and posttherapy bone marrow evaluations, were studied in 12 patients who received anti-BCMA CAR T-cell therapy. Results Bone marrow findings after CAR T-cell therapy were available in 6 of 12 cases, 3 of which showed markedly hypocellular marrow with either markedly reduced or essentially absent hematopoiesis. One case showed a hypocellular marrow with trilineage hematopoiesis, while the remaining 2 cases showed persistent involvement by plasma cell myeloma. Reticulin stains did not reveal significant fibrosis. Ten patients had anemia, and 8 patients had leukopenia and thrombocytopenia at day 90 posttherapy. Long-term follow-up showed persistent disease in 10 of 12 cases. Conclusions Prolonged cytopenias occur in most patients after BCMA CAR T-cell therapy with bone marrow evaluations demonstrating associated marked hypocellularity with minimal or no hematopoiesis without an increase in fibrosis.

Anti-CD19 chimeric antigen receptor (CAR) T-cell and anti-CD20 bispecific antibody therapies (BsAbs) are rapidly moving to earlier treatment lines for patients with B-cell non-Hodgkin lymphoma (B-NHL). The rapid pace of the advancement of these T-cell-engaging therapies is juxtaposed by a lack of a comprehensive understanding of the scope and kinetics of immunodeficiency following these treatments. We review emerging studies detailing the safety and efficacy of CD19 CAR-T and CD20 BsAbs in earlier lines for B-NHL, as well as a discussion of the limited knowledge of immune recovery following these treatments. We integrate the limited consensus prevention and management recommendations, advocating that the management of secondary immunodeficiency following these transformative therapies is an urgent unmet need in immune oncology research. A collaboration between hematologists/oncologists and immunologists in the management of these patients is critical to optimize patient care. [ABSTRACT FROM AUTHOR]

Chemotherapy-induced cytopenia (CIC) is characterized by neutropenia, anemia, and thrombocytopenia, which are common and serious complications in cancer treatment. These conditions affect approximately 60% of patients undergoing chemotherapy and can significantly impact quality of life, treatment continuity, and overall survival. The use of growth factors, including granulocyte colony-stimulating factors (GCSFs), erythropoietin-stimulating agents (ESAs), and thrombopoietin receptor agonists (TPO-RAs), has emerged as a promising strategy for managing CIC. However, the use of these growth factors must be approached with caution. This review provides an overview of the mechanisms, efficacy, and safety of growth factors in the management of CIC. Additionally, we discuss predictive markers for treatment response, potential risks, and highlight areas for future research. [ABSTRACT FROM AUTHOR]

Simple Summary: The SRealCLL study collected real-world data on patients with chronic lymphocytic leukaemia (CLL) from Spanish hospitals between 2016 and 2018, focusing on their adverse events (AEs) and healthcare resource use by applying natural language processing to analyse healthcare records. A total of 534 CLL patients were identified, categorizing them into watch and wait (W&W), first-line treatment (1L), and relapse/refractory with second-line treatment (2L) groups. The main antineoplastic treatments were ibrutinib (64.8%) and bendamustine + rituximab (12.6%) in 1L, and ibrutinib (62.1%) and venetoclax (15.5%) in 2L. The study findings revealed that patients in 1L or 2L treatments, representing 43.1% and 10.9% of the cohort, respectively, frequently encountered AEs such as anaemia and thrombocytopenia. These patients also had more outpatient and emergency visits, with almost half of 1L patients requiring hospitalization due to AEs. In conclusion, individuals undergoing 1L or 2L CLL treatments often have heightened healthcare needs, emphasizing the importance of effective and safe management of the disease that optimizes resource utilization, particularly considering the typically older and comorbid nature of this patient population. Objectives: The SRealCLL study described the occurrence of adverse events (AEs) and healthcare resource utilization in patients with chronic lymphocytic leukaemia (CLL) using artificial intelligence in a real-world scenario in Spain. Methods: We collected real-world data on patients with CLL from seven Spanish hospitals between January 2016 and December 2018, focusing on their AE and healthcare service utilization. Data extraction from electronic health records of 385,904 patients was performed using the EHRead® technology, which is based on natural language processing and machine learning. Results: Among the 534 CLL patients finally included, 270 (50.6%) were categorized as watch and wait (W&W), 230 (43.1%) as first-line treatment (1L), and 58 (10.9%) as relapse/refractory with second-line treatment (2L). The median study follow-up periods were 14.4, 8.4, and 6 months for W&W, 1L, and 2L, respectively. The most common antineoplastic treatments were ibrutinib (64.8%) and bendamustine + rituximab (12.6%) in 1L, and ibrutinib (62.1%) and venetoclax (15.5%) in 2L. Among the most frequent AEs, anaemia and thrombocytopenia presented higher rates in the treated groups (1L and 2L) compared with W&W (2.01 and 2.32 vs. 0.93; p ≤ 0.05 and 1.29 and 1.62 vs. 0.42; p ≤ 0.05). Moreover, several AEs, such as major bleeding, digestive symptoms, general symptoms, or Richter syndrome, were more frequent in 1L than W&W (all p ≤ 0.05). No differences were shown between groups in the rates of outpatient visits. However, rates of outpatient visits due to AE were higher in 1L than in W&W (1.07 vs. 0.65, p ≤ 0.05). The rates of patients being hospitalized were higher in the treated groups compared to W&W (1.68 and 1.9 vs. 0.88; p ≤ 0.05), and those due to AE were higher in 1L than W&W (1.23 vs. 0.60; p ≤ 0.05). Conclusions: Patients with CLL in 1L or 2L treatments often require healthcare resources due to AEs, particularly cytopenias. The methodology used in this study likely enabled us to identify higher rates of AEs that may be underreported using other real-world approaches. Addressing AEs with effective agents that maximize patient safety and optimize healthcare resource use is crucial in this typically older and comorbid population. [ABSTRACT FROM AUTHOR]

Introduction: Systemic Lupus Erythematosus (SLE) can be diagnosed using the 2012 criteria of the Systemic Lupus International Collaborating Clinics (SLICC) and, more recently, the 2019 criteria of the European League Against Rheumatism/American College of Rheumatology (EULAR/ACR). Hematological involvement is scored differently by these classifications. Our objective was to compare both criteria in a cohort of children with autoimmune cytopenia (AIC)-associated SLE. Method: We included 79 patients with childhood-onset AIC as the first manifestations of SLE. Results: The median age at SLE diagnosis was 14.5 years (1.1–21.4 years). The SLICC criteria were fulfilled by 76/79 (96%) patients and the EULAR/ACR criteria by 72/79 (91%) patients during follow-up. The SLICC and EULAR/ACR criteria were discordant (not concomitantly fulfilled) in 25/79 (32%) patients. Non-hematological clinical manifestations were more frequently observed in SLE diagnosis when the criteria were concordant (30/54, 56%) than when they were not (5/25, 20%) (p = 0.004). In 16/25 (64%) discordant patients, the SLICC criteria allowed earlier diagnosis of SLE. Finally, the attribution of a maximum weight of 6 to the hematological involvement of the EULAR/ACR criteria increased the sensitivity thereof from 63/79 (80%) to 76/79 (96%) in our population. Conclusion: The SLICC 2012 and EULAR/ACR 2019 criteria do not effectively diagnose SLE in children when AIC is the predominant feature. The SLICC criteria appear to be more effective in this population of SLE patients. An increase in the maximum weight of hematological involvement to 6 increases the sensitivity of the EULAR/ACR criteria for SLE diagnosis in children. [ABSTRACT FROM AUTHOR]

ABSTRACT Shwachman‐Diamond syndrome (SDS) is a rare inherited bone marrow failure syndrome characterized by the triad of exocrine pancreatic dysfunction, cytopenia, and skeletal abnormalities. We report a 5‐month‐old boy with SDS who presented with generalized ichthyosis in the neonatal period that evolved into more eczematous skin eruptions, accompanied by severe failure to thrive. This report highlights the importance of including SDS as a differential diagnosis in patients who present with early ichthyosis, failure‐to‐thrive, gastrointestinal symptoms and cytopenia.

Background: Rituximab (RTX) is a monoclonal antibody that has been increasingly used in the treatment of myasthenia gravis (MG). In most studies, the therapeutic protocol of RTX has been similar to that adopted for B cell lymphoma, with an increasing number of studies aimed at exploring the efficacy of low-dose RTX in MG. However, the beneficial effects of low-dose RTX in MG remain a subject of critical debate. Methods: This study was conducted following the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines. Two reviewers (Xishuai Yang and Bingxia Li) independently conducted searches across multiple databases, including PubMed, MEDLINE, EMBASE, Web of Science, Cochrane Library, and China National Knowledge Infrastructure (CNKI). A meta-analysis, utilizing representative forest plots, was performed to assess "Improved clinical status" and changes in the Quantitative Myasthenia Gravis (QMG) score before and after treatment. Results: A total of 17 studies involving 292 patients were included in the meta-analysis. A noticeable improvement in clinical status was observed in 91% of patients at the final follow-up after therapy (95% CI: 84–96%, P < 0.001). The QMG score showed a significant reduction following the treatment, with a standardized mean difference (SMD) of −1.69 (95% CI: −2.21 to −1.16, Z = 6.29, P < 0.001). In the acetylcholine receptor antibody-positive myasthenia gravis (AChR-MG) group, 90% of patients achieved improved clinical status (95% CI: 80–97%, P < 0.001) and the QMG score significantly decreased after low-dose RTX treatment, with an SMD of −1.51 (95% CI: −0.80 to −2.21, Z = 4.50, P < 0.001). In the muscle-specific kinase antibody-positive myasthenia gravis (MuSK-MG) group, 97% of patients achieved improved clinical status (95% CI: 89–100%, P < 0.001). The QMG score also significantly decreased following low-dose RTX treatment, with an SMD of −2.31 (95% CI: −2.99 to −1.62, Z = 6.60, P < 0.001). Adverse effects were reported in 29 out of 207 patients (14%, including infusion reactions in 22 patients (10.1%), infections in three patients (1.45%), cytopenia in two patients (0.96%), eosinophilia in one patient (0.48%), and hemiplegia in one patient (0.48%). Additionally, one patient (0.48%) succumbed to complications from invasive thymoma. Conclusion: Our meta-analysis shows that low-dose RTX is both effective and safe for treating MG.

Recognition of patients with multiple diagnoses, and the unique challenges they pose to clinicians and laboratorians, is increasing rapidly as genome-wide genetic testing grows in prevalence. We describe a unique patient with dual diagnoses of PDCD10 -related cerebral cavernous malformations and ETV6 -related thrombocytopenia with associated neutropenia. She presented with brain abscesses as an infant, which is highly atypical for these disorders in isolation. Confirming her diagnoses depended on thorough phenotyping both during and after her acute illness. Furthermore, the causative variant in ETV6 is a novel single-exon deletion that required multiple modalities with manual review to confirm, including unique use of polymorphic nucleotides in trio exome data. She illustrates the special challenges of patients with multiple diagnoses, and the multiple tools clinicians and laboratorians must use to treat them. [ABSTRACT FROM AUTHOR]

Objectives Large granular lymphocytic leukemia (LGLL) represents a rare neoplasm of mature T cells or natural killer (NK) cells, with an indolent clinical course. Diagnosing LGLL can be challenging because of overlapping features with reactive processes and other mimickers. Methods By presenting 2 challenging cases, we elucidate the differentiation of LGLL from its mimics and highlight potential diagnostic pitfalls. A comprehensive review of the clinicopathologic features of LGLL was conducted. Results Large granular lymphocytic leukemia displays a diverse spectrum of clinical presentations, morphologies, flow cytometric immunophenotypes, and molecular profiles. These features are also encountered in reactive conditions, T-cell clones of uncertain significance, and NK cell clones of uncertain significance. Conclusions In light of the intricate diagnostic landscape, LGLL workup must encompass clinical, morphologic, immunophenotypic, clonal, and molecular findings. Meeting major and minor diagnostic criteria is imperative for the accurate diagnosis of LGLL. [ABSTRACT FROM AUTHOR]

Cytotoxic T-lymphocyte associated antigen-4 (CTLA-4) is a costimulatory receptor exhibiting a potent inhibitory signal on antigen-activated immune responses. A soluble form, sCTLA-4, has been identified and was found to be increased in several autoimmune diseases. We aimed to evaluate serum levels of sCTLA-4 in different immune cytopenias, and to determine its possible relation to the disease activity. We measured serum levels of sCTLA-4 in 47 patients with immune cytopenias and compared them to 47 age- and sex-matched healthy controls. sCTLA-4 levels were significantly higher in patients with immune cytopenias compared to healthy controls (p < 0.001), however, levels were comparable between different groups of immune cytopenias (p = 0.084). Serum sCTLA-4 inversely correlated with age at diagnosis and hemoglobin level (p = 0.048, and p = 0.039 respectively), while it directly correlated with disease duration (p = 0.023) as well as markers of hemolysis including reticulocyte count, serum LDH and indirect bilirubin (p = 0.025; p = 0.019; p = 0.004 respectively). In the AIHA group, serum sCTLA-4 levels were significantly lower in patients in remission compared to patients with active disease (p = 0.026). Children with immune cytopenia exhibit significantly higher levels of circulating sCTLA-4 which correlated with disease activity, yet the prognostic significance and its use to tailor treatment regimen require additional studies.

The article presents a case study of a 6-month-old African American girl diagnosed with familial hemophagocytic lymphohistiocytosis (HLH) triggered by enterovirus, characterized by prolonged fever, pancytopenia, and abnormal liver function. Topics include the diagnostic criteria and challenges of HLH, the therapeutic strategies employed to manage the condition, and genetic underpinnings associated with PRF1 mutations, which affect the perforin protein critical for immune response regulation.

Inborn errors of immunity are monogenic disorders that predispose patients to immune dysregulation, autoimmunity, and infection. Some autoimmune diseases, such as autoimmune cytopenias, systemic lupus erythematosus, and inflammatory bowel diseases, are increasingly recognized as phenotypes of inborn errors of immunity. The objective of this article was to identify red flags or clinical/laboratory markers to suspect inborn errors of immunity in patients with autoimmune cytopenias, systemic lupus erythematosus, and inflammatory bowel diseases through a systematic literature review. The study followed the systematic reviews and meta-analysis guidelines (PRISMA). After selection, we included 36 articles, and their methodological quality was verified using the Joanna Briggs Institute tools for individual risk of bias analysis. The principal red flags in autoimmune cytopenias are chronic, recurrent, and refractory cytopenias, recurrent infection, severe infectious complications associated with immunosuppressive treatment, and chronic lymphoproliferation. In systemic lupus erythematosus, red flags include age of onset before five years, severe organ involvement, chilblain lesions, and chronic lymphoproliferation. For inflammatory bowel diseases, red flags are an age of onset before two years, resistance to conventional therapies, atypical endoscopic or histologic findings, and consanguineous parents. Autoimmune diseases may be the primary manifestation of inborn errors of immunity in pediatric and adult patients. An early diagnosis of a monogenic disorder allows for the tailoring of effective treatment plans, providing prognostic information to families, and offering genetic counseling.

The clinical course of patients with chronic hemolytic anemia can be complicated by the development of splenomegaly and consequent hypersplenism. This may warrant management by medical or surgical methods. Furthermore, in some patients, splenic manipulation may be warranted in the absence of hypersplenism, spleen being the primary site of red cell destruction. Wherever possible, splenectomy is avoided or deferred in view of the life-long risks of infection and thrombosis associated with this procedure. Optimal management in hemolytic anemia, therefore, incorporates prevention of hypersplenism as one of the key treatment goals.
