Machado T, Lawrence J, Eriksson D, Donohue J. A need for greater awareness: a mixed methods study of patient and healthcare professional perspectives on the diagnosis journey for haemophagocytic lymphohistiocytosis (HLH). Hematology 2024; 29:2358261. [PMID: 38934707 DOI: 10.1080/16078454.2024.2358261] [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: 08/04/2023] [Accepted: 05/14/2024] [Indexed: 06/28/2024] Open
Abstract
OBJECTIVES Our aim was to better understand and raise awareness of the diagnosis journey and quantify any barriers for timely diagnosis of haemophagocytic lymphohistiocytosis (HLH), to support patients' struggle with diagnosis and reduce time to diagnosis. METHODS Patients diagnosed with, or caregivers for those diagnosed with primary or secondary HLH and physicians involved in the treatment of HLH were recruited. Quantitative interviews were undertaken with patients/caregivers to quantify key elements of the diagnosis journey, followed by qualitative interviews with participants. Interviews took place between March-May 2021. RESULTS Thirty-three patients/caregivers and nine physicians took part in this mixed methods study. Lack of physician awareness of HLH was a common frustration for patients/caregivers, causing delayed diagnosis. All physicians indicated bone-marrow testing is a key step in the diagnosis process, and some patients/caregivers had frustrations around testing. Emergency care doctors, although not usually involved in the diagnosis process, were among the most-seen specialists by patients/caregivers. Patients/caregivers suggested potential improvements in available information, such as providing information on treatment options and condition management. DISCUSSION Patients/caregivers and physicians agreed on the need to raise overall awareness of HLH signs/symptoms among priority groups of physicians to recognise how signs/symptoms can progress and develop. Improvements in the testing process and communication would directly impact the speed of diagnosis and support patients/caregivers during the diagnostic journey, respectively. CONCLUSION Raising awareness of key issues, such as signs/symptoms, tests and diagnostic procedures, and improved communication and support for patients/caregivers, are key to speeding up HLH diagnosis and improving outcomes.

Abstract
Background Providing optimal care for patients with bleeding disorders according to national standards remains a challenge at designated Hemophilia Treatment Centers (HTCs). Improved care may reduce bleeds and costs. Objectives To improve care and demonstrate cost savings by 1) reducing preventable hospitalizations and emergency room visits (PHER) for bleeding, 2) increasing use of prophylaxis in severe hemophilia, and 3) improving patient-HTC communication and primary care engagement. Methods Prospective quality improvement project using the Define, Measure, Analyze, Improve, and Control methodology to implement uniform guideline-based bleeding disorder care at a rural HTC (N = 88). Intervention used a standardized physician checklist, improved communication, and reserved physician time for urgent management. Outcomes were determined by retrospective chart review; urgent management was tracked prospectively. Results Intervention significantly reduced PHER by 85.4%. Use of prophylaxis in persons with severe hemophilia increased from 58.8% to 100%; attainment of a primary care physician and electronic portal enrollment met outcomes for intervention success. HTC clinic visit attendance was low at 55.2%. The majority of patients (71.6%) had at least 1 outpatient urgent episode (mean, 0.72 episode per year), and 93% had nonurgent management (mean, 9.3 episodes per year) occurring outside of a clinic visit. Hospital PHER factor cost in the group was reduced by 94.5%, from $11,800 to $640 per patient per year-a cost savings of $982,088 yearly. Conclusion This collaborative study shows that implementation of a carefully designed quality improvement project, such as uniform guidelines with focus on strengthening ambulatory management, led to improved outcomes and cost savings.

Ann Hematol 2023; 102:3251-3259. [PMID: 37561154 PMCID: PMC10567857 DOI: 10.1007/s00277-023-05398-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 02/01/2023] [Indexed: 08/11/2023]
Abstract
Secondary hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease. In the present retrospective study, we aimed to investigate coagulation disorders and their outcome implications in patients with secondary HLH. We evaluated clinical characteristics and the relationship between coagulation indices and prognosis in HLH patients (n = 141). The information, including clinical symptoms, laboratory indicators, and coagulation indices, was evaluated. Coagulation disorders and bleeding events occurred in 95 (67.4%) and 60 (42.6%) patients, respectively. A coagulation index analysis primarily showed elevated levels of D-Dimer, the international standardized ratio (INR), prothrombin time (PT), activated partial thromboplastin time (APTT), and thrombin time (TT), while the prothrombin activity, fibrinogen levels, and platelet levels were significantly decreased. Dominant disseminated intravascular coagulation (DIC) occurred in 76 patients (53.9%). Patients with lymphoma-associated hemophagocytic syndrome (LAHS) frequently exhibited apparent coagulation disorders. Multivariate analysis revealed that age ≥ 29.5 years, bleeding events, APTT ≥ 47.3 s, fibrinogen ≤ 1.68 g/L, and absolute neutrophil counts (ANC) of ≤ 1.21 × 109/L were independent prognostic factors. We thereby devised a prognostic scoring system and stratified patients into low-risk (0-2 points), intermediate-risk (3-4 points), and high-risk (5-7 points) groups, and the 1-year overall survival rates in the above-mentioned groups were 66.40%, 40.00%, and 2.30%, respectively (P < 0.0001). In conclusion, coagulation dysfunctions and bleeding tendencies were common characteristics in HLH patients. We constructed a novel prognostic score model based on APTT, fibrinogen level, ANC, age, and bleeding events, which had superior prognostic value compared with these markers alone.

Abstract
Both cytokine release syndrome (CRS) and sepsis are clinical syndromes rather than distinct diseases and share considerable overlap. It can often be challenging to distinguish between the two, but it is important given the availability of targeted treatment options. In addition, several other clinical syndromes overlap with CRS and sepsis, further making it difficult to differentiate them. This has particularly been highlighted in the recent coronavirus disease-2019 pandemic. As we start to understand the differences in the inflammatory markers and presentations in these syndromes, hopefully we will be able to enhance treatment and improve outcomes.

Abstract
Background Hemophagocytic lymphohistiocytosis (HLH), a syndrome of immune hyperactivation and abnormal regulation that causes life-threatening inflammation, is mainly characterized by fever, hepatosplenomegaly, cytopenia, and other symptoms. Reactive HLH (rHLH) is typically secondary to immune deregulation caused by underlying rheumatologic, infectious, or malignant conditions. Malignancy-associated HLH (M-HLH) continues to be a critical health problem worldwide. Most malignancies associated with HLH are hematologic tumors, and M-HLH in non-hematologic tumors very rarely occurs. Case Report A 34-year-old Chinese woman had a history of persistent fever, acute dizziness, and bicytopenia. She was found to have developed bilateral ovarian cancer. Additional tests showed splenomegaly, hemophagocytes in the bone marrow, low natural killer activity, and hyperferritinemia, which met the diagnostic criteria put forth in the Histiocyte Society HLH-2004. The patient was treated with correcting anemia, increased platelets, and glucocorticoid therapy but showed no response. She progressively deteriorated and died 55 days later. Conclusion Hemophagocytic lymphohistiocytosis related to a solid tumor is extremely rare. To the best of the authors’ knowledge, the present case was the first to report rHLH secondary to ovarian adenocarcinoma. It is very significant for a better understanding of the disease mechanisms of HLH and should attract the attention of hematologists and other clinicians as the condition progresses and the cost of treating it increases.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a heterogeneous, life-threatening clinical syndrome. There are scarce data on the quality of care in HLH or data comparing treatment patterns and outcomes between different triggers. We aimed to examine quality-of-care indicators and outcomes in adults with various HLH triggers. In this multi-centre retrospective cohort study of adult HLH in the province of Alberta, Canada (1999-2019), we examined quality indicators including diagnostic testing, time to diagnosis and treatment and trigger identification. We also compared treatment regimens and outcomes across HLH triggers. Logistic regression was used to identify predictors of etoposide use. Overall survival (OS) was estimated using the Kaplan-Meier method. We identified 97 patients; 66 (68%) were male. Triggers included malignancy (36%), infection (35%), autoimmune disease (21%) and idiopathic/others (8%). Specialized tests such as sCD25 (53%) and natural killer degranulation assay (19%) were under-performed, as were testing for infectious triggers. Etoposide was administered in only 33 (34%). Neutropenia, hyperbilirubinemia and hyperferritinemia, but not age, sex and comorbidities, were significant predictors of etoposide use. At median follow-up of 32 months, median OS was 18.8 months. Worse OS was seen in malignancy-associated and idiopathic HLH (log-rank P < 0.001). Our study showed low rates of specialized testing such as sCD25 and a low rate of etoposide use. Development of a standardized provincial protocol has the potential to improve quality of care in adult HLH.

Abstract
BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) is a rare syndrome characterized by uncontrolled immune activation and high risk of death. There is scarce data on the incidence of bleeding and thromboembolism in HLH. OBJECTIVES To determine the cumulative incidence of bleeding and thromboembolism and impact on survival in adults with HLH. PATIENTS/METHODS We conducted a multicenter retrospective cohort study of adults with HLH in Alberta, Canada (1999-2019). The cumulative incidence of bleeding and thromboembolism were calculated, accounting for competing risks. Cox proportional hazards models were used to assess the impact of bleeding and thromboembolism on overall survival (OS). RESULTS We identified 97 adults with HLH (median age 46 years). Venous thromboembolism (VTE) occurred in 11 (11%) patients at a median of 9 days from admission. ISTH major bleeding and clinically relevant non-major bleeding occurred in 39 (40%) patients, at a median of 16 days after admission. Nadir platelet count (adjusted odds ratio [aOR] 1.8 per log decrease, 95% confidence interval [CI] 1.2-2.8) and mechanical ventilation (aOR 4.9, 95% CI 1.8-14.8) were independent predictors of bleeding on multivariable analysis. Adjusting for competing risks, the 90-day cumulative incidences of bleeding and thromboembolism were 39% and 13%, respectively. The median OS was 18.8 months. VTE, but not bleeding, was significantly associated with adverse OS (adjusted hazard ratio 2.5, 95% CI 1.1-5.7). CONCLUSIONS In adults with HLH, VTE appears more common than previously described and is a predictor of mortality, although this may be due to unadjusted confounding. VTE prevention and treatment are challenging due to high bleeding rates.

Abstract
Hemophagocytic syndrome (HPS) is a rare disease in clinical practice, and there are often cases of delayed diagnosis. At present, researchers have applied 18F-FDG PET/CT in the differential diagnosis of HPS, but no consensus has been formed. Therefore, this study aims to systematically evaluate the application value of 18F-FDG PET/CT in the diagnosis of HPS patients. PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Wangfang database (Wangfang), and Chinese Biomedical Network (CBM) were searched to collect the relevant studies of 18F-FDG PET/CT in the diagnosis of HPS. Data from the articles were screened and extracted for meta-analysis using Stata16.0 software. A total of 10 retrospective studies, including 300 patients, were included in this meta-analysis. The meta-analysis results showed that the pooled sensitivity was 0.82 (95% CI: 0.67-0.95), specificity was 0.72 (95% CI: 0.51-0.86), positive likelihood ratio was 2.89 (95% CI: 1.46-5.75), positive likelihood ratio was 0.25 (95% CI: 0.12-0.54), diagnostic odds ratio was 2.89 (95% CI: 1.46-5.75), and AUC was 0.84 (95% CI: 0.81-0.87). The SUVmax in the liver, spleen, lymph nodes, and bone marrow of HPS patients was greater than 2.5, and the SUVmax in the spleen, lymph nodes, and bone marrow of malignant HPS patients was higher than that of benign HPS patients. The difference was statistically significant (P < 0.05). According to the existing literature evidence, 18F-FDG PET/CT is an effective method for diagnosing HPS.

Abstract
Objective 18F-fluorodeoxyglucose (FDG) PET/CT is often used for detecting malignancy in patients with newly diagnosed hemophagocytic lymphohistiocytosis (HLH), with acceptable sensitivity but relatively low specificity. The aim of this study was to improve the diagnostic ability of 18F-FDG PET/CT in identifying malignancy in patients with HLH by combining 18F-FDG PET/CT and clinical parameters. Materials and Methods Ninety-seven patients (age ≥ 14 years) with secondary HLH were retrospectively reviewed and divided into the derivation (n = 71) and validation (n = 26) cohorts according to admission time. In the derivation cohort, 22 patients had malignancy-associated HLH (M-HLH) and 49 patients had non-malignancy-associated HLH (NM-HLH). Data on pretreatment 18F-FDG PET/CT and laboratory results were collected. The variables were analyzed using the Mann-Whitney U test or Pearson’s chi-square test, and a nomogram for predicting M-HLH was constructed using multivariable binary logistic regression. The predictors were also ranked using decision-tree analysis. The nomogram and decision tree were validated in the validation cohort (10 patients with M-HLH and 16 patients with NM-HLH). Results The ratio of the maximal standardized uptake value (SUVmax) of the lymph nodes to that of the mediastinum, the ratio of the SUVmax of bone lesions or bone marrow to that of the mediastinum, and age were selected for constructing the model. The nomogram showed good performance in predicting M-HLH in the validation cohort, with an area under the receiver operating characteristic curve of 0.875 (95% confidence interval, 0.686–0.971). At an appropriate cutoff value, the sensitivity and specificity for identifying M-HLH were 90% (9/10) and 68.8% (11/16), respectively. The decision tree integrating the same variables showed 70% (7/10) sensitivity and 93.8% (15/16) specificity for identifying M-HLH. In comparison, visual analysis of 18F-FDG PET/CT images demonstrated 100% (10/10) sensitivity and 12.5% (2/16) specificity. Conclusion 18F-FDG PET/CT may be a practical technique for identifying M-HLH. The model constructed using 18F-FDG PET/CT features and age was able to detect malignancy with better accuracy than visual analysis of 18F-FDG PET/CT images.

[PMID: 35004761 PMCID: PMC8740551 DOI: 10.3389/fmed.2021.792677] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 11/22/2021] [Indexed: 11/13/2022] Open
Abstract
Purpose: Hemophagocytic lymphohistiocytosis (HLH) is a rare and severe disease with a poor prognosis. We aimed to determine if 18F-fluorodeoxyglucose (18F-FDG) PET/CT-derived radiomic features alone or combination with clinical parameters could predict survival in adult HLH. Methods: This study included 70 adults with HLH (training cohort, n = 50; validation cohort, n = 20) who underwent pretherapeutic 18F-FDG PET/CT scans between August 2016 and June 2020. Radiomic features were extracted from the liver and spleen on CT and PET images. For evaluation of 6-month survival, the features exhibiting p < 0.1 in the univariate analysis between non-survivors and survivors were selected. The least absolute shrinkage and selection operator (LASSO) regression analysis was used to develop a radiomics score (Rad-score). A nomogram was built by the multivariate regression analysis to visualize the predictive model for 3-month, 6-month, and 1-year survival, while the performance and usefulness of the model were evaluated by calibration curves, the receiver operating characteristic (ROC) curves, and decision curves. Results: The Rad-score was able to predict 6-month survival in adult HLH, with area under the ROC curves (AUCs) of 0.927 (95% CI: 0.878–0.974) and 0.869 (95% CI: 0.697–1.000) in the training and validation cohorts, respectively. The radiomics nomogram combining the Rad-score with the clinical parameters resulted in better performance for predicting 6-month survival than the clinical model or the Rad-score alone. Moreover, the nomogram displayed superior discrimination, calibration, and clinical usefulness in both the cohorts. Conclusion: The newly developed Rad-score is a powerful predictor for overall survival (OS) in adults with HLH. The nomogram has great potential for predicting 3-month, 6-month, and 1-year survival, which may timely guide personalized treatments for adult HLH.

Safi S, Shanbhag S, Hambley BC, Merrill SA. Systems controls are needed to reduce mistaken tests for hemophagocytic lymphohistiocytosis, results of a prospective quality-improvement cohort study. Medicine (Baltimore) 2021; 100:e26509. [PMID: 34190181 PMCID: PMC8257870 DOI: 10.1097/md.0000000000026509] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Accepted: 06/10/2021] [Indexed: 01/04/2023] Open
Abstract
Medical diagnosis and therapy often rely on laboratory testing. We observed mistaken testing in evaluations for hemophagocytic lymphohistiocytosis (HLH) that led to delays and adverse outcomes. Physicians were mistakenly ordering interleukin-2 and quantitative natural killer cell flow cytometry, rather than soluble interleukin 2 receptor (sIL2R) or qualitative natural killer functional tests in the evaluation of patients suspected to have HLH.We initiated a prospective quality improvement project to reduce mistaken testing, reduce delays in correct testing due to mistaken ordering, and improve HLH evaluations. This consisted of provider education, developing an evaluation algorithm, and ultimately required systems interventions such as pop-ups and removal of the mistaken tests from the electronic ordering catalog.Active education reduced mistaken testing significantly in HLH evaluations from baseline (73.3% vs 33.3%, P = .003, relative risk reduction (RRR) 54.5%), but failed to meet the pre-specified RRR cutoff for success (70%). Education alone did not significantly reduce the proportion of HLH evaluations with delays in sIL2R testing (23.3% vs 7.4%, P = .096). Mistaken testing increased after the active intervention ended (33.3% vs 43.5%, P = .390, with RRR 40.7% from baseline. Mistaken test removal was successful: mistaken testing dropped to 0% (P < .001, RRR 100%), saved $14,235 yearly, eliminated delays in sIL2R testing from mistaken testing (23.3% vs 0%, P = .008), and expedited sIL2R testing after admission for HLH symptoms (14.6 days vs 3.8 days, P = .0012). These data show systems controls are highly effective in quality improvement while education has moderate efficacy.

Abstract
BACKGROUND Hemophagocytic lymphohistiocytosis (HLH), an uncontrolled overactivation of the immune system, is well characterized in pediatric patients, yet, much less is known about this life-threatening condition in adult patients. As HLH is often complicated by organ failure, patients will require admission to the intensive care unit for organ support therapy. However, recognition of HLH patients in the intensive care unit (ICU) is challenged by the clinical overlap with sepsis. Here, we analyze HLH patients to better understand its clinical presentation, diagnosis, and treatment. METHODS For the purpose of this retrospective observational study, we searched for suspected and diagnosed adult HLH of all patients admitted to at least one adult surgical, anesthesiological or medical ICU between January 2006 and August 2018 at the university hospital Charité - Universitätsmedizin Berlin. All cases were reviewed by two HLH experts, who confirmed or declined the diagnosis. RESULTS Of 6,340 ICU patients with ferritin measurement, 40 suffered from HLH (0.63%). Of these, in-hospital mortality was 60.0% over all cases, which was highest in malignancy-associated HLH (71.4%). Infections were identified as most common triggers (42.5%). A variety of 19 different treatment strategies were applied. Non-survivors showed higher ferritin at diagnosis compared with survivors (P = 0.021), which was also seen in multivariable analyses. A minimum ferritin of 4083 μg/L after diagnosis was most predictive for 30-day mortality (AUC 0.888, 95% CI 0.771-1.000; sensitivity 93.8%, specificity 78.9%). CONCLUSIONS Mortality in adult HLH patients in the ICU is high, particularly in malignancy-associated HLH. Infections are the most frequent HLH triggers in critically ill patients. At present, there is no standardized treatment for HLH in adult patients available. Assessment of ferritin is valuable for diagnosis, prognosis, and treatment monitoring. TRIAL REGISTRATION The study was registered with www.ClinicalTrials.gov (NCT02854943) on August 1, 2016.

Abstract
OBJECTIVES Hemophagocytic lymphohistiocytosis is a cytokine release syndrome caused by uncontrolled immune activation resulting in multiple organ failure and death. In this systematic review, we aimed to analyze triggers, various treatment modalities, and mortality in critically ill adult hemophagocytic lymphohistiocytosis patients. DATA SOURCES MEDLINE database (PubMed) at October 20, 2019. STUDY SELECTION Studies and case series of patients greater than or equal to 18 years old, of whom at least one had to be diagnosed with hemophagocytic lymphohistiocytosis and admitted to an ICU. DATA EXTRACTION Source data of studies and case series were summarized and analyzed on an individual basis. Multivariable logistic regression analysis was performed adjusting for age, sex, and trigger groups. Each single treatment agent was entered as a dichotomous variable to determine treatments associated with survival, regardless if given alone or in combination. DATA SYNTHESIS In total, 661 patients from 65 studies and case series were included. Overall mortality was 57.8%. Infections were the most frequent trigger (49.9%), followed by malignancies (28.0%), autoimmune diseases (12.1%), unknown triggers (9.4%), and drugs (0.6%). Treatment with IV immunoglobulins was associated with improved survival (odds ratio, 0.548; 95% CI, 0.337-0.891; p = 0.015), while treatment with cyclosporine was associated with increased risk of death (odds ratio, 7.571; 95% CI, 3.702-15.483; p < 0.001). Considering different trigger groups separately, same results occurred only for infection-triggered hemophagocytic lymphohistiocytosis. No information was available on disease severity and other confounding factors. CONCLUSIONS Mortality of hemophagocytic lymphohistiocytosis in the ICU is high. Most common triggers were infections. Results of survival analyses may be biased by treatment indication and disease severity. Future studies prospectively investigating treatment tailored to critically ill hemophagocytic lymphohistiocytosis patients are highly warranted.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening immune dysregulation syndrome characterized by uncontrolled immune cell activation. Timely diagnosis is important, since early treatment can improve survival rates. However, completing all assessments needed to reach ≥5 positive criteria out of the 8 HLH-2004 criteria can be time consuming and may delay timely initiation of treatment. Hence, we applied a data-driven approach to identify a minimal parameter set for early decision-making towards the initiation of HLH-specific treatment. We retrospectively evaluated 165 patients from five Dutch tertiary hospitals with suspected HLH. Sixteen pHLH (median age 0.5 years) and 70 sHLH patients (median age 8.7 years) were identified using the HLH-2004 criteria. Clustering analysis and multi-receiver operator characteristics were used to identify parameters distinctive of HLH. The presence of either increased ferritin, cytopenia in ≥2 lineages, or splenomegaly distinguished HLH from non-HLH cases with a negative predictive value of 100%. A minimal parameter set consisting of 2 major criteria (phagocytosis and splenomegaly) and 3 minor criteria (cytopenia, increased ferritin, and increased triglycerides/low fibrinogen) predicted HLH with 95% (88-99) sensitivity and 94% (86-98) specificity. This finding was replicated in an independent retrospective validation cohort of 109 US patients (n = 109). By dividing a subset of the HLH-2004 criteria into major and minor criteria, this strategy uses the evaluation of less than 5 criteria to quickly identify patients with HLH. When confirmed in a prospective setting, this approach could be of value for timely diagnosis and treatment of HLH.

The Treatment Effect of Protamine on Severe Coagulopathy in Epstein-Barr Virus-Associated Hemophagocytic Lymphohistiocytosis: Case Reports and Literature Review. Indian J Hematol Blood Transfus 2021; 37:90-95.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening disease, which is characterized by severe systemic inflammation with cytokine storm as well as histologic evidence of hemophagocytosis. Besides, coagulopathy and hemorrhages are two common severe complications in HLH patients. Recent literatures indicate that Epstein-Barr virus (EBV) infection is one of the important triggers for the disease. In the study, we present three cases of EBV related HLH (EBV-HLH) with coagulopathy in patients with distinct backgrounds. Case 1 is a 45-year-old female diagnosed with EBV associated NK/T cell lymphoproliferative disorder (EBV-T/NK-LPD) and EBV-HLH. Case 2 is a 17-year-old male with a diagnosis of EBV-T-LPD and EBV-HLH. Case 3 is a 51-year-old male and also diagnosed with EBV-T-LPD and EBV-HLH. All cases were given with treatment with HLH-94 protocol, and the symptoms of the three patients improved. Furthermore, during the treatment, protamine, which has not been reported in the literature previously, was given to the three cases with EBV-HLH, and our results showed that after treatment with protamine, the coagulopathy and bleedings in these patients were improved rapidly. Unfortunately, the three patients relapsed soon and died despite intensive treatment. However, these cases suggest that protamine may serve as a potential treatment option for coagulation associated with EBV-HLH. Besides, the study helps us improve the understanding of the EBV-HLH related coagulation disorders, and provide a potential strategy for future treatment of the disease.

Abstract
Background Hemophagocytic lymphohistiocytosis (HLH) is a severe or even fatal inflammatory state. Epstein–Barr virus (EBV) infection-associated HLH (EBV-HLH) is one of the most common secondary HLH and suffers a very poor prognosis. Allo-HSCT is often required for refractory EBV-HLH, but some patients still cannot proceed to the next allo-HSCT due to various factors. This study aimed to observe the efficacy of HLA-mismatched granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood stem cells (GPBSCs) infusion for refractory EBV-HLH. Methods A retrospective case-control study of refractory EBV-HLH patients with GPBSC infusion from HLA-mismatched donors after chemotherapy (as GPBSC group) and sole chemotherapy (as control group) was performed. Efficacy was evaluated 2 and 4 weeks and all patients were followed-up until March 1, 2018. Results There were 18 cases who accepted infusion between March 2016 and Sep 2017 and 19 were randomly selected from refractory EBV-HLH patients who underwent salvage therapy during the same period for the control group. In GPBSC group, WBC (p = 0.017), Fbg (p = 0.040), and ferritin (p = 0.039) improved significantly after treatment. The overall response rate was 66.7% (CR 22.2%, PR 44.4%). However, there are no significant differences in changes of WBC, HGB, PLT, TG, Fbg, Ferritin, AST, ALT, and T-bil between two groups. Only the Fbg level was recovered better in the GPBSC infusion group (p = 0.003). In the GPBSC group, EBV-DNA decreased significantly after 2 weeks (p = 0.001) and 4 weeks (p = 0.012) after treatment, and the effect of the decrease was significantly better than that of the chemotherapy alone group in 2 weeks but not 4 weeks (p2w = 0.011, p4w = 0.145). The median survival time in the infusion group was 20.4 weeks [95% CI 10.9, 29.9], and the median survival time in the control group was 10.8 weeks [95% CI 0–24.34]. In the short-term, the infusion group’s survival rate was better (2-month 88.89% vs. 52.63%, p = 0.008; 3-month 83.33% vs. 47.09%, p = 0.012), but there was no difference in OS (p = 0.287). Conclusions Infusing GPBSCs combined with chemotherapy is effective, especially in decreasing EBV-DNA, performs better than chemotherapy alone, and improves short-term survival rate. GPBSC infusion is suggested as a bridging treatment method to allo-HSCT.

Clinical and imaging features in adult patients with bone marrow haemophagocytosis with and without haemophagocytic lymphohistiocytosis: a single-institution experience. Clin Radiol 2020; 75:641.e1-641.e8.

Abstract
AIM To evaluate clinical, laboratory, imaging findings, and outcomes of adult patients with bone marrow haemophagocytosis (BMH) who meet the diagnostic criteria for haemophagocytic lymphohistiocytosis (HLH) with those who do not meet the criteria. MATERIALS AND METHODS A pathology database search was performed from 2009 to 2019 to identify adult patients with BMH. Electronic medical records of 41 patients were reviewed to distinguish those who fulfil the HLH-2004 diagnostic guidelines, which identified 22 patients (11 men; mean age, 53.5 years) who met the criteria (HLH+) and 19 patients (13 men; mean age, 54.7 years) who did not meet the criteria (HLH-). Multi-modality imaging was reviewed to record imaging features. Clinical, laboratory, imaging findings, and outcomes were compared between the two groups using Fisher's exact test and Wilcoxon test. RESULTS Malignancy (non-Hodgkin's lymphoma) was the major trigger for both groups. 86% of HLH+ and 31% of HLH- patients presented with fever. Compared to the HLH- group, the HLH+ group exhibited higher serum ferritin, triglycerides, and lower fibrinogen levels (p<0.05). Alveolar opacities and hepatosplenomegaly were the most common imaging findings identified in both groups. Median overall survival of HLH+ and HLH- were 123.5 (interquartile range [IQR]: 40.7-681.7 days) and 189 days (IQR: 52-1680 days), respectively. Distribution of imaging features and overall survival did not differ between the groups. CONCLUSION Malignancy is the major trigger for BMH in both HLH+ and HLH- groups. HLH+ and HLH- groups have similar imaging manifestations or clinical outcomes. Therefore, presence of BMH alone is correlated with high morbidity and mortality.

Abstract
BACKGROUND Hemophagocytic lymphohistiocytosis is a cytokine-driven inflammatory syndrome that is associated with substantial morbidity and mortality. Overall survival in adult patients with secondary haemophagocytic lymphohistiocytosis remains suboptimal, and novel therapeutic strategies are needed. The phosphorylation-dependent activation of the Janus family kinases JAK1 and JAK2 are hallmarks of the final common pathway in this disease. We therefore aimed to determine the activity and safety of ruxolitinib, a JAK inhibitor, in adults with secondary haemophagocytic lymphohistiocytosis. METHODS We performed an open-label, single-centre, pilot study of ruxolitinib in adults with secondary haemophagocytic lymphohistiocytosis at the University of Michigan Rogel Cancer Center (Ann Arbor, MI, USA). We included patients aged 18 years or more who fulfilled at least five of the eight HLH-2004 criteria for hemophagocytic lymphohistiocytosis. Discontinuation of corticosteroids was not required for enrolment in this study. Patients received oral ruxolitinib (15 mg twice a day) on a continuous 28-day cycle, or until disease progression or unacceptable toxicity. The primary endpoint was overall survival at 2 months from the first dose of ruxolitinib. Secondary endpoints included the assessment of adverse events, response (defined as the assessment of all quantifiable signs and laboratory abnormalities included in the diagnostic criteria for haemophagocytic lymphohistiocytosis), and pharmacodynamic biomarkers. Analyses were done in all treated patients with available data. This study is registered with ClinicalTrials.gov, number NCT02400463, and is still recruiting. FINDINGS As of Feb 7, 2019, five patients had been enrolled. The first patient was enrolled in February, 2016. No deaths were recorded, with a median follow-up of 490 days (IQR 190-1075). 2-month overall survival was 100% (95% CI 57-100). Regarding response, resolution of symptoms (either partial or complete) and disease-associated laboratory abnormalities was observed in all five patients. Cytopenias improved in all patients within the first week of treatment, leading to relatively rapid transfusion independence, discontinuation of corticosteroids, and hospital discharge. A single serious adverse event (ie, grade 4 febrile neutropenia) was reported. One patient discontinued treatment because of grade 2 extremity pain and no treatment-related deaths were observed. Improvements in inflammatory markers (eg, ferritin, soluble IL-2 receptor) and T cells and monocytes activation (ie, decreased STAT1 phosphorylation) were observed following treatment. INTERPRETATION These preliminary data suggest that ruxolitinib is active, well tolerated, and manageable in the outpatient setting in patients with secondary haemophagocytic lymphohistiocytosis. Given the paucity of effective, non-myelosuppressive therapies, these preliminary findings have important therapeutic implications for patients with haemophagocytic lymphohistiocytosis and other cytokine-release syndromes and warrant further investigation.

Merrill SA, Brodsky RA, Lanzkron SM, Naik R. A case-control analysis of hyperhemolysis syndrome in adults and laboratory correlates of complement involvement. Transfusion 2019; 59:3129-3139. [PMID: 31292968 DOI: 10.1111/trf.15445] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2019] [Revised: 05/10/2019] [Accepted: 06/18/2019] [Indexed: 12/17/2022]
Abstract
BACKGROUND Hyperhemolysis syndrome (HS) is a poorly understood, severe hemolytic anemia provoked by transfusion. Both host and donor RBCs are destroyed in HS; thus, transfusion paradoxically worsens anemia. Risk factors and mechanism of HS are unknown. STUDY DESIGN AND METHODS A retrospective case-control analysis was performed on adults with HS. Patients with HS were matched 1:1 with matched, transfused controls, and HS risk factors were analyzed with multivariable logistic regression. HS samples were analyzed for complement deposition by flow cytometry, and an in vitro model of bystander hemolysis was developed. RESULTS Forty-one patients with 54 episodes of HS were identified in a 26-year period from 1992 to 2018. Of the HS episodes, only 18.5% were associated with a new alloantibody, and such patients were more tolerant of additional transfusion in the acute episode (p = 0.005). Thirteen percent of episodes were fatal, and HS recurred in 52.6%. Alloimmunization (odds ratio [OR], 17.3), non-B blood type (OR, 9.8), D antigen (OR, 9.1), and infection (OR, 5.5) were associated with HS on multivariable analysis. Hyperbilirubinemia was predictive of fatal HS (OR, 33.6). Increased complement was observed on RBCs during HS episodes, and the in vitro model of bystander hemolysis recapitulated complement decoration of sickled RBCs. CONCLUSIONS HS is associated with significant morbidity, mortality, and recurrence. Risk factors such as known alloimmunization, blood group, and infection predispose to HS. Bystander complement activation may drive HS. These factors may help physicians refine risk-benefit assessments for transfusion and guide further therapeutic development.
