Abstract
BACKGROUND Little is known about viral-associated hemophagocytic lymphohistiocytosis (HLH) in Oman. This study was done to assess the epidemiology, clinical features and outcome of viral-associated HLH in our setting. METHODS We retrospectively reviewed children (0-18 years) managed for viral-associated HLH at the Sultan Qaboos University Hospital, Oman, over a 15-year period (2006-2020). Patients' medical records were used to describe their demographic, clinical and laboratory features, management and outcome. RESULTS Fifty-six children were managed for HLH at Sultan Qaboos University Hospital over the last 15 years (2006-2020) of whom a third (19; 34%) had a viral trigger. The median age at the time of diagnosis of viral-associated HLH was 83 (13-96) months. Fever, cytopenia, hyperferritinemia and evidence of hemophagocytosis in bone marrow were the most consistent findings. Most of these children had either genetic predisposition to HLH (8/19; 42%) or underlying immunodeficiency secondary to malignant conditions or chemotherapy/hematopoietic stem cell transplantation (6/19; 32%). Epstein-Barr virus (9; 47%) followed by cytomegalovirus (6; 31%) was the most common viral trigger in our setting. Treatment included antivirals (8; 42%), HLH 2004 protocol (4; 21%), rituximab (4; 21%) and hematopoietic stem cell transplantation (3; 16%). Fourteen children (74%) had full recovery. CONCLUSIONS In our small cohort, viral-associated HLH was more frequently encountered in children with genetic predisposition to HLH or children with underlying immunodeficiency. In addition, we found that the outcome is overall good for children who have no genetic predisposition to HLH and children with genetic predisposition who underwent hematopoietic stem cell transplantation.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is an immune response disorder that is usually fatal despite treatment. It is characterized by a dysregulation in natural killer (NK) T-cell function, causing activation of lymphocytes and histiocytes, resulting in a cytokine storm, end-organ damage, and eventually death. In this report, we describe the case of a previously healthy 38-year-old Caucasian man who presented with fever, nausea, vomiting, abdominal pain, myalgias, and weight loss for one week after inactivated influenza vaccination. The initial evaluation showed leukocytosis, lactic acidosis, and a severely elevated creatine kinase level (19,639 IU/L). The presentation was consistent with a diagnosis of sepsis, likely secondary to viral etiology and rhabdomyolysis. Subsequently, he rapidly deteriorated, requiring mechanical ventilation and developed refractory shock requiring pressor support and continuous veno-venous hemofiltration for acute kidney injury due to rhabdomyolysis. Later, he developed bicytopenia, hyperferritinemia, hypertriglyceridemia, and elevated inflammatory markers, raising the possibility of underlying HLH. Further tests showed low NK cell cytotoxicity and elevated sCD25. The H-score, which is a clinical tool to estimate the probability of HLH, showed an 88-93% probability of that potentially fatal disorder. The patient was treated with pulse-dose corticosteroids, intravenous immunoglobulins (IVIGs), and anakinra. He had a prolonged and complicated hospital stay for about two months. However, he was able to slowly recover. We believe that he developed secondary HLH in the setting of vaccination. Although rare, an early suspicion of HLH leads to the early initiation of directed therapy with immunosuppressant that would limit morbidity and mortality.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of pathologic immune activation. It occurs because of severe inflammation due to uncontrolled proliferation of activated lymphocytes and histiocytes, characterized by the production of excessive levels of cytokines. Virus-associated HLH is a well-known entity, and parvovirus B19 is one of the common causes. Parvovirus B19 can also affect blood cell lineages. Therefore, HLH may be accompanied by several diseases such as cytopenia, aplastic anemia, and myelodysplastic syndrome. Herein, we report the case of a patient with hereditary spherocytosis who was diagnosed with parvovirus B19-induced HLH and aplastic crisis. A 7-year-old girl presented to our hospital with fever, pleural effusion, pancytopenia, hepatosplenomegaly, and hypotension. A bone marrow biopsy was performed under the suspicion of HLH, which revealed hemophagocytes. The diagnostic criteria for HLH were met, and prompt chemoimmunotherapy was initiated considering the clinically unstable situation. Her health improved rapidly after initiating treatment. Further study revealed that she had hereditary spherocytosis, and parvovirus B19 had caused aplastic crisis and HLH. The patient's clinical progress was excellent, and chemoimmunotherapy was reduced and discontinued at an early stage. This case shows that aplastic crisis and HLH can coexist with parvovirus B19 infection in patients with hereditary spherocytosis. Although the prognosis was good in this case of HLH caused by parvovirus B19, early detection and active treatment are essential.

Clinical spectrum and therapeutic management of systemic lupus erythematosus-associated macrophage activation syndrome: a study of 20 Moroccan adult patients. Clin Rheumatol 2022; 41:2021-2033. [PMID: 35179662 DOI: 10.1007/s10067-022-06055-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 01/02/2022] [Accepted: 01/04/2022] [Indexed: 12/12/2022]
Abstract
OBJECTIVE The objective of this study was to describe the clinical and laboratory manifestations, triggers factors, treatment, and outcome of MAS complicating SLE. METHODS We retrospectively analyzed the medical records of adult patients with SLE for a period of 8 years (2009-2016) and identified patients who had developed MAS. We conducted statistical analysis to identify factors associated with MAS. RESULTS Among 208 consecutive lupus patients, 20 patients (19 women) were identified having MAS. The mean age of patients was 35.4 ± 10 years. MAS revealed lupus in 7 patients. In the others, the delay between diagnosis of SLE and MAS was 33,3 months. All cases required hospital admission, and 2 patients were admitted to the intensive care unit. An anemia (hemoglobin < 10 g/dL) was found in all patients. A thrombopenia was observed in 19 (95%) cases. Hypertriglyceridemia and hyperferritinemia were present in all patients. All patients had anti-nuclear antibodies and anti-double-stranded DNA antibodies. Bone marrow aspiration showed hemophagocytosis in 15 (94%) cases. The mean SLEDAI was 20.95 corresponding to an SLE of a very high activity. The mean H-Score was 233.85. MAS was associated with a lupus flare in 13 patients. Documented bacterial infections, viral infections, and a breast cancer were respectively diagnosed in 4, 3, and 1 cases respectively. The corticosteroids were administered in all patients. Intravenous cyclophosphamide was used together with corticosteroids in 6 patients, mycophenolate mofetil in 2 cases and azathioprine in 2 cases. Intravenous immunoglobulin was given in 4 cases, etoposide in one case and rituximab was used as the third line treatment in one patient. All infectious episodes were also treated by broad spectrum antibiotics. All patients had a good outcome without any mortality at the management, with a mean follow-up of 24 months. The clinical parameters significantly associated with MAS were fever (p = 0,001), splenomegaly (p < 0.0001), lymphadenopathy (p < 0.0001), oral and/or nasopharyngeal ulceration (p = 0.04), arthritis (p = 0.017), and pulmonary signs (p = 0.003). Laboratory parameters associated with MAS were anemia (p < 0.0001), thrombopenia (p < 0.0001), hyperferritinemia (p < 0.0001), hypertriglyceridemia (p < 0.0001), SLEDAI (p < 0.0001), and H-Score (p < 0.0001). Receiver operating characteristic (ROC) analysis identified optimal cutoff values of ferritin (> 695 ng/mL) and SLEDAI (> 13.5) to predict the occurrence of MAS in SLE. CONCLUSION MAS was observed in 9.62% Moroccan adult patients with SLE. SLE flare and infection were the common triggers of MAS in our study. Our study indicates that the occurrence of unexplained fever, splenomegaly, lymphadenopathy, profound cytopenia, hyperferritinemia, hypertriglyceridemia, high SLEDAI, and H-Score should raises the possibility of the diagnosis of MAS in SLE patients. Early diagnosis and urgent therapeutic management improves the overall prognosis. Key Points • Macrophage activation syndrome (MAS) is an underdiagnosed complication of systemic lupus erythematosus (SLE). The prevalence of this complication in this study is nearly 10%. • The diagnosis of MAS represents a major challenge for clinicians, as it could mimic a SLE flare up or be confused with infections. Validated diagnostic criteria for MAS in adults secondary to SLE are urgently needed. • In this study, the H-score calculate the individual risk of adult patients having reactive MAS. The cut-off value for the H-score was 190.5 (sensitivity 96.7%, specificity 97.6%). • The prognosis of MAS with SLE is good in our study. However, in the literature MAS may be a fatal condition in SLE patients. Prospective studies are necessary to confirm these results.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is an uncommon hyperinflammatory syndrome characterized by excessive activation of macrophages and T-cells with high cytokines levels, causing multiorgan dysfunction.HLH has been associated with variable infectious etiologies, such as tuberculosis(TB). TB-associated HLH (TB-HLH) is a rare condition, but it is fatal if not treated. The diagnosis of TB-HLH is challenging and might be missed if not highly considered. The classic manifestations of HLH include pancytopenia, organomegaly, lymphadenopathy, and coagulopathy. Herein, we present a young immunocompetent adult diagnosed with disseminated TB complicated by HLH. Our patient responded well to the combination of antituberculosis therapy(ATT), corticosteroid, and intravenous immunoglobulin(IVIG). This case highlights the importance of considering this fatal complication in TB patients.

Abstract
BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) is a rapidly progressive and potentially life-threatening disorder. Identifying risk factors and timely adjustment of the given treatment regimens is critical to reducing the early mortality in HLH patients. Hypocholesterolemia has been reported to be associated with poor prognosis in a variety of critical illnesses. However, serum cholesterol is rarely studied in HLH patients, and its prognostic value is unclear. METHODS We conducted a retrospective cohort study in National Clinical Research Center for Child Health and Disorders (Chongqing), identifying pediatric HLH patients (including genetically confirmed pHLH and not genetically confirmed pHLH) diagnosed with the HLH-2004 protocol and treated with immunochemotherapy between January 2008 and December 2020. The patients' blood lipid levels at initial diagnosis of HLH, including triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), were reviewed based on electronic medical records. Both Cox and logistic regression models were used to estimate the effects of blood lipid indicators on early death (within 30 days after diagnosis). RESULTS A total of 353 patients were enrolled in the study, with a median age at diagnosis of 45 months. The observed 30-day mortality rate was 19.05% (64/336, 17 were lost to follow-up) and Kaplan-Meier-estimated 3-year survival rate was 61.67% (95% CI, 56.27%-67.59%). DNA-targeted sequencing of HLH-related genes was performed in 173 (49.0%, 173/353) patients (not all patients with suspected pHLH underwent genetic testing), and 29 patients were diagnosed with genetically confirmed pHLH. Lipid panel was performed in 349 patients: 91.98% (321/349) had TG ≥ 1.80 mmol/L, 62.75%(219/349) had TG ≥ 3.00 mmol/L, 92.84% (324/349) had HDL-C ≤ 1.04 mmol/L, 58.74% (205/349) had LDL-C ≤ 1.30 mmol/L and 24.64% (86/349) had TC ≤ 3.11 mmol/L. TC ≤ 3.11 mmol/L and BUN ≥ 7.14 mmol/L were the independent risk factors for 30-day mortality [HR(95%CI): 2.85(1.46, 5.57) and 2.90(1.48, 5.68), respectively]. The presence of one of these risk factors increased the 30-day mortality rate by 6-fold [HR = 6.24, 95%CI: (3.18, 12.22)] and the presence of two risk factors by nearly 10-fold [HR = 9.98, 95%CI: (4.23, 23.56)] compared with the patients with no risk factors. CONCLUSION Severe derangement of lipoproteins is common in children with HLH, and decreased TC is an independent risk factor for early death. Hypocholesterolemia should be included as a biomarker during the diagnosis and management of HLH patients.

Abstract
A 30-year-old Honduran male with recently diagnosed AIDS presented with a 1-month history of worsening abdominal pain, diarrhea, and fever. Initial investigations were notable for Cytomegalovirus viremia and diffuse lymphadenopathy. Axillary lymph node biopsy demonstrated necrotizing lymphadenitis with disseminated histoplasmosis. Despite aggressive antimicrobial therapy he continued to clinically deteriorate raising suspicion for hemophagocytic lymphohistiocytosis. The patient met 5 of 8 HLH-2004 diagnostic criteria and was successfully treated with dexamethasone and etoposide per the HLH-94 protocol. Despite the high mortality rates and poor clinical outcomes of hemophagocytic lymphohistiocytosis in patients living with HIV/AIDS, this case demonstrates that this high-risk patient population can be successfully treated and survive acquired hemophagocytic lymphohistiocytosis. Furthermore, our case stresses the importance of maintaining a broad differential diagnosis in patients living with HIV/AIDS who present with sepsis.

Abstract
Inborn errors of immunity (IEI) are a heterogenous group of disorders driven by genetic defects that functionally impact the development and/or function of the innate and/or adaptive immune system. The majority of these disorders are thought to have polygenic background. However, the use of next-generation sequencing in patients with IEI has led to an increasing identification of monogenic causes, unravelling the exact pathophysiology of the disease and allowing the development of more targeted treatments. Monogenic IEI are not only seen in a pediatric population but also in adulthood, either due to the lack of awareness preventing childhood diagnosis or due to a delayed onset where (epi)genetic or environmental factors can play a role. In this review, we discuss the mechanisms accounting for adult-onset presentations and provide an overview of monogenic causes associated with adult-onset IEI.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a complex, often under-recognized hyperinflammatory immune dysregulation syndrome arising in a diverse range of clinical scenarios and conditions. The accurate and timely diagnosis of HLH is crucial for patient survival, and usually requires a high level of clinical suspicion. The histologic corollary to clinical HLH - hemophagocytosis - is neither necessary nor sufficient for the diagnosis of HLH, as it may be seen in a variety of reactive conditions and may be absent in true HLH. Nevertheless, the finding of hemophagocytosis in specific clinical situations should prompt consideration of HLH and further testing to exclude the condition. While traditionally described in bone marrow, identification of hemophagocytosis in other tissues, including lymphoid, splenic, liver, or neural tissue, can be an important asset to the overall recognition of HLH. In this review we discuss the underlying pathophysiology and etiologies of HLH, morphologic aspects of hemophagocytosis and its associated histologic findings in different tissues, and give a brief overview of diagnostic criteria and clinical evaluation.

Abstract
OBJECTIVE Hemophagocytic lymphohistiocytosis is a hyperinflammatory syndrome that often requires critical care support and remains difficult to diagnose. These guidelines are meant to aid in the early recognition, diagnosis, supportive care, and treatment of patients with hemophagocytic lymphohistiocytosis in ICUs. DATA SOURCES The literature searches were performed with PubMed (MEDLINE). STUDY SELECTION Keywords and medical subject headings terms for literature search included "macrophage activation syndrome," hemophagocytic lymphohistiocytosis," and "hemophagocytic syndrome." DATA EXTRACTION The Histiocyte Society developed these consensus recommendations on the basis of published reports and expert opinions with level of evidence provided for each recommendation. They were endorsed by the Society of Critical Care Medicine. DATA SYNTHESIS Testing for hemophagocytic lymphohistiocytosis should be initiated promptly in all patients admitted to ICUs with an unexplained or disproportionate inflammatory response, especially those with rapid clinical deterioration. Meeting five or more of eight hemophagocytic lymphohistiocytosis 2004 diagnostic criteria serves as a valuable diagnostic tool for hemophagocytic lymphohistiocytosis. Early aggressive critical care interventions are often required to manage the multisystem organ failure associated with hemophagocytic lymphohistiocytosis. Thorough investigation of the underlying triggers of hemophagocytic lymphohistiocytosis, including infections, malignancies, and autoimmune/autoinflammatory diseases, is essential. Early steroid treatment is indicated for patients with familial hemophagocytic lymphohistiocytosis and is often valuable in patients with acquired hemophagocytic lymphohistiocytosis (i.e., secondary hemophagocytic lymphohistiocytosis) without previous therapy, including macrophage activation syndrome (hemophagocytic lymphohistiocytosis secondary to autoimmune/autoinflammatory disease) without persistent or relapsing disease. Steroid treatment should not be delayed, particularly if organ dysfunction is present. In patients with macrophage activation syndrome, whose disease does not sufficiently respond, interleukin-1 inhibition and/or cyclosporine A is recommended. In familial hemophagocytic lymphohistiocytosis and severe, persistent, or relapsing secondary macrophage activation syndrome, the addition of prompt individualized, age-adjusted etoposide treatment is recommended. CONCLUSIONS Further studies are needed to determine optimal treatment for patients with hemophagocytic lymphohistiocytosis in ICUs, including the use of novel and adjunct therapies.

Abstract
Background For a patient presenting with fever, multiple lymphadenopathy and splenomegaly, pathogen infection should be preferentially considered, followed by lymphoid malignancies. When traditional laboratory and pathological detection cannot find the pathogenic microorganism, metagenomic sequencing (MGS) which targets the person’s genome for exceptional genetic disorders may detect a rare pathogen. Case presentation Here, we introduced the diagnostic clue of a case of multicentric Castleman disease (MCD) with hemophagocytic syndrome which was elicited from the detection of human herpesvirus-8 in the blood of a HIV-1 infected person by MGS technology during pathogen inspection. This case highlights the need to increase the awareness of MCD among clinicians and pathologists. Conclusions MGS technology may play a pivotal role in providing diagnostic clues during pathogen inspection, especially when pathogens are not detectable by conventional methods.

Abstract
Background Hemophagocytic syndrome (HPS) is a severe hyperinflammatory disease, whose diagnosis is based on the HLH-2004 criteria. In secondary forms of HLH (sHLH), the primary goal is treating the triggering factors such as COVID-19 (Coronavirus disease 2019). The link between the cytokine storm related to COVID-19 and development of sHLH has already been reported since the onset of pandemic, but little is known about clinical manifestations of HLH which develop after the patient’s recovery from mild symptomatic or asymptomatic Sars-CoV-2 infection. Case presentation We describe the case of a woman diagnosed with sHLH related to previous Sars-CoV-2 infection and successfully treated with steroids, colchicine, etoposide and ruxolitinib. Conclusions Our report suggests that HLH-like syndrome might be secondary to Sars-CoV-2 infection, even if the patient utterly recovered from the mildly symptomatic viral infection. In addition, we underline the treatment with low dose ruxolitinib plus etoposide as a potential choice for Sars-CoV-2 infection related HLH.

Abstract
We report the first documented case of hepatitis E virus-associated haemophagocytic lymphohistiocytosis. This case emphasizes the fact that infectious agents other than those classically described should be taken into consideration as a potential trigger of virus-associated haemophagocytic syndrome. Prompt recognition is crucial to start early treatment of the underlying infection and possibly improve the outcome of this frequently fatal syndrome.

Abstract
Hemophagocytic syndrome is a disorder of the mononuclear phagocytic system resulting in uncontrolled hemophagocytosis and cytokine overproduction. We report the first case of hemophagocytic syndrome, which occurred in a pregnantfemale patient 14 years after kidney transplant who displayed an atypical presentation and who had septic shock following cytomegalovirus infection. The patient, a-39-year-old woman at 27 weeks gestation with end-stage renal disease of unknown etiology, was admitted 14 years after living-donor kidney transplant (donor was her father) with high-grade fever, cough, and pancytopenia. Her immunosuppressant regimen included tacrolimus, azathioprine, and prednisone. Initially, she was hospitalized in the intensive care unit for septic shock without an identifiable focus of infection. She received intravenous broad-spectrum antibiotics before being transferred to our department following optimization of her hemodynamic status. Hemophagocytic syndrome was suspected, and bone marrow aspirate was performed, revealing macrophages with hemophagocytic activity. We confirmed the diagnosis of hemophagocytic syndrome given the presence of more than 5 criteria. We extensively investigated the underlying cause of hemophagocytic syndrome, and we diagnosed cytomegalovirus-induced hemophagocytic syndrome in a pregnant patient receiving immunosuppressive therapy after kidney transplantation. She was treated with corticosteroids and intravenous immunoglobulin. At 31 weeks gestation, she underwent a cesarean section; the baby developed newborn respiratory distress syndrome and died despite adequate resuscitation. We administered ganciclovir for 15 days following an increased cytomegalovirus viral load after delivery, leading to complete recovery.To date, optimal therapeutic and diagnostic guidelines for pregnancy-related hemophagocytic syndrome in female kidney transplant recipients are not well defined, and both patient and allograft survival rates remain low.

Abstract
Enteric fever is a common infectious disease of the tropical world. Common age group involved is children aged between 5 and 10 years. In addition to diarrhea, it may lead to extraintestinal infections including aseptic meningitis, hepatitis, cholecystitis, acute abdomen, intestinal perforation, pneumonia, psychosis, and ataxia. Hematologic complications leading to hemophagocytosis have a prevalence of < 1%. Salmonella meningitis has an incidence of 6% with poor prognosis neurological sequelae. We report a rare case of enteric fever that presented with hemophagocytic syndrome and S. meningitis. Response to third-generation cephalosporins is dramatic, eventually giving good prognosis.

Abstract
Histoplasmosis-associated hemophagocytic lymphohistiocytosis is a rate but lethal disease in immunocompromised hosts. Unusual clinical presentations make diagnosing invasive fungal infection even more challenging. Here we present a case of hemophagocytic lymphohistiocytosis secondary to progressive disseminated histoplasmosis presenting as cellulitis in a patient with systemic lupus erythematous. A high index of suspicion combined with histopathology and molecular diagnostic techniques are important to establish an accurate and timely diagnosis of opportunistic infections in immunocompromised patients.

Abstract
Epstein-Barr virus (EBV) primary infection usually presents with classic symptoms of infectious mononucleosis (IM) like fever, lymphadenopathies and tonsillopharyngitis. Liver damage is frequently mild and self-limited and there are only a few cases of severe EBV-induced cholestatic hepatitis and jaundice reported in the literature. The authors present the case of a 22-year-old woman who was admitted with acute fever and jaundice. Physical examination revealed posterior cervical lymphadenopathies and painful hepatosplenomegaly. Laboratorial findings suggested an obstructive cause for jaundice but ultrasound and magnetic resonance cholangiopancreatography excluded biliary duct pathology. Heterophile antibodies were negative but EBV-specific antibodies revealed isolated positive viral capsid antigen (VCA) immunoglobin (Ig) M suggesting the diagnosis of early phase of EBV primary infection. The diagnosis of EBV-induced cholestatic hepatitis was confirmed after identification of EBV deoxyribonucleic acid (DNA) in blood and by liver biopsy. Supportive management was provided and, despite an initial clinical deterioration, the patient had a favorable outcome. EBV is a virus with a high prevalence worldwide, mainly subclinical, and jaundice is a rare manifestation of the infection. Although the majority of the patients recover without sequelae, progression to liver failure has been described and a careful assessment for complications is mandatory. Therefore, EBV infection should be included in the comprehensive differential diagnosis of jaundice in all age groups.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) in acute human immunodeficiency virus (HIV) patients has been scarcely reported in the English literature. To the best of our knowledge, only 12 cases have been described. We present a case of a 27-year-old male with no past medical history who was admitted with a new-onset headache, fever, night sweats, and chills. Further laboratory tests revealed transaminitis, leukopenia, thrombocytopenia, positive HIV antigen/antibody test, and markedly elevated ferritin levels, which promoted our suspicion of HLH. This case demonstrates HLH as an unusual presentation of HIV during its seroconversion stage. This report adds a rare disease process to the available literature, and we emphasize that markedly elevated ferritin levels in acute HIV patients should raise suspicion toward a diagnosis of HLH.

Abstract
Recently, more and more attention has been paid on adult hemophagocytic lymphohistiocytosis (HLH), a disease with complicated symptoms and high mortality. In order to analyze the clinical characteristics and prediction risk factors of mortality, we designed a retrospective study with 1-year follow-up and included 155 patients admitted to Tongji Hospital diagnosed as HLH. One hundred seven patients formed the training cohort for nomogram development, and 48 patients formed the validation cohort to confirm the model's performance. All patients' clinical characteristics, laboratory results, medical records, and prognosis were analyzed. Among all the 107 patients in the training cohort, 46 were male and 61 were female, with the median age of 49.0 (IQR 31.0-63.0). The 1-year mortality rate was 43.9% (47/107) and 45.8% (22/48) in the training and validation cohort, respectively. And further multivariate logistic regression analysis in the training cohort showed that male (odds ratio 5.534, 95% CI 1.507-20.318, p = 0.010), altered mental status (11.876, 1.882-74.947, p = 0.008), serum ferritin ≥ 31,381 μg/L (8.273, 1.855-36.883, p = 0.006), and IL-6 ≥ 18.59 pg/mL (19.446, 1.527-247.642, p = 0.022) were independent risk factor of mortality. A nomogram included the four prediction factors mentioned above was also tabled to help clinicians evaluate the probability of poor outcome. Area under the receiver operating characteristic curve (AUROC) analysis, calibration curves, and decision curve analysis (DCA) certify the accuracy and the clinical usefulness of the nomogram. Our research reveals that male, altered mental status, serum ferritin ≥ 31,381 µg/L, and IL-6 ≥ 18.59 pg/mL are four independent predictors for poor prognosis. Doctors should pay more attention to patients with altered mental status, high serum ferritin, and IL-6 level, who have a higher risk of death.

Abstract
Haemophagocytic lymphohistiocytosis (HLH) is a rare diagnosis that carries a high degree of mortality. We present this case of a previously healthy 22-year-old woman, who was admitted acutely ill to the hospital. One week prior, she had been seen by her primary care physician for fatigue and malaise. At that time, she was noted to have anterior and posterior cervical lymphadenopathy. She was referred to the emergency room and was diagnosed with acute Epstein-Barr virus (EBV) mononucleosis based on her clinical symptoms and positive heterophile antibody test. She was discharged after an uneventful 48-hour stay on the wards. She represented 7 days after discharge with cough, fatigue, nausea, vomiting, epigastric abdominal pain, diarrhoea, weight loss and subjective fevers. She had also reported haematemesis, epistaxis and melaena. Vital signs included temperature 36.9°C, blood pressure 90/50 mm Hg, heart rate 130 beats per minute and respiratory rate 32 breaths per minute. Physical examination was notable for an acutely ill appearing woman with scleral icterus, hepatosplenomegaly and palpable cervical and axillary lymphadenopathy. Complete blood count showed pancytopaenia with haemoglobin 59 g/L (normal 120-160 g/L), white blood cell count 2.7×109/L (normal 4-10.5×109/L) and platelet count 50×109/L (normal 150-450×109/L). The white blood cell count differential included 58% neutrophils (normal 38%-77%) with immature neutrophils in band form elevated at 45% (normal <14%), 16% lymphocytes (normal 20%-48%), 7% monocytes (normal <12%) and no eosinophils (normal <6%). Blood smear revealed anisocytosis, poikilocytosis and hypochromia. Coagulation panel showed elevated levels of d-dimer level at 1.39 µg/mL (normal <0.45 µg/mL), prolonged prothrombin time at 34.4 s (normal 11-15 s), prolonged activated partial thromboplastin time of 55.6 s (normal 25-34 s), prolonged international normalised ratio at 3.31 (normal <1.1) and low fibrinogen 60 mg/dL (normal >200 mg/dL). Lipid panel showed cholesterol at 114 mg/dL (normal 125-200 mg/dL), triglycerides 207 mg/dL (normal 30-150 mg/dL), high-density lipoprotein cholesterol 10 mg/dL (normal 40-60 mg/dL) and low-density lipoprotein cholesterol 63 mg/dL (normal <100 mg/dL). Other lab abnormalities included elevated ferritin of 6513 ng/mL (normal 10-150 ng/mL) and elevated lactate dehydrogenase of 1071 unit/L (normal 95-240 unit/L). Soluble interleukin-2 receptor alpha level was elevated at 60 727 units/mL (normal 223-710 units/mL). Fluorodeoxyglucose-positron emission tomography (FDG-PET) scan showed abnormal tracer localisation within the paratracheal, hilar, pelvic, abdominal and subcarinal lymph nodes, along with FDG-PET positive hepatosplenomegaly. A bone marrow biopsy showed hypercellular marrow (95% cellularity) with trilineage haematopoiesis, haemophagocytic cells, polytypic plasmacytosis and T-cell lymphocytosis, along with positive latent membrane protein-1 immunohistochemical staining for EBV. EBV quantitative DNA PCR showed >1 million copies. These findings were consistent with a diagnosis of HLH secondary to EBV infection. Despite intense therapy with the HLH-94 protocol, the patient expired from her illness after a prolonged hospital course.

Abstract
Hemophagocytic lymphohistiocytosis is a rare complication in Rickettsia typhi infections. We report the case of a 2-year-old boy with sudden night-onset fever, pallor, neck adenopathy and erythematous macular rash on the thorax, thighs and buttocks. During admission, he developed hyponatremia, hypoalbuminemia, anemia, thrombocytopenia, leukopenia, neutropenia, liver damage, hemorrhages and persistent fever. No hematological improvement was observed after the initial management, neoplastic diseases were discarded by bone marrow aspiration and lymph node biopsy; hemophagocytic lymphohistiocytosis was diagnosed. By immunohistochemistry and indirect immunofluorescence, murine typhus was also diagnosed and doxycycline was started with transitory recovery. Later, the child developed kidney failure and distributive shock that evolved to cardiac arrest and death. This is the first case report in Mexico on a fatal murine typhus associated with hemophagocytic lymphohistiocytosis in which the etiology was evidenced by histopathology.

Abstract
Immunocompromised mouse strains expressing human transgenes are being increasingly used in biomedical research. The genetic modifications in these mice cause various cellular responses, resulting in histologic features unique to each strain. The NSG-SGM3 mouse strain is similar to the commonly used NSG (NOD scid gamma) strain but expresses human transgenes encoding stem cell factor (also known as KIT ligand), granulocyte-macrophage colony-stimulating factor, and interleukin 3. This report describes 3 histopathologic features seen in these mice when they are unmanipulated or after transplantation with human CD34+ hematopoietic stem cells (HSCs), virally transduced hCD34+ HSCs, or a leukemia patient-derived xenograft. The first feature is mast cell hyperplasia: unmanipulated, naïve mice develop periductular pancreatic aggregates of murine mast cells, whereas mice given the aforementioned human cells develop a proliferative infiltrative interstitial pancreatic mast cell hyperplasia but with human mast cells. The second feature is the predisposition of NSG-SGM3 mice given these human cells to develop eosinophil hyperplasia. The third feature, secondary hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS)-like disease, is the most pronounced in both its clinical and histopathologic presentations. As part of this disease, a small number of mice also have histiocytic infiltration of the brain and spinal cord with subsequent neurologic or vestibular signs. The presence of any of these features can confound accurate histopathologic interpretation; therefore, it is important to recognize them as strain characteristics and to differentiate them from what may be experimentally induced in the model being studied.

Abstract
OBJECTIVES To describe the clinical profile, intensive care needs, outcome, and predictors of mortality in critically ill children with hemophagocytic lymphohistiocytosis. DESIGN Retrospective case series. SETTING PICU of a tertiary care teaching hospital in North India. PATIENTS Children 2 months to 12 years old with the diagnosis of hemophagocytic lymphohistiocytosis admitted to PICU from January 2012 to April 2019 (7¼ yr). INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Sixty-two children with hemophagocytic lymphohistiocytosis (60 secondary and two primary) were enrolled. The median (interquartile range) age of the study group was 82 months (50.5-124 mo). The median (interquartile range) Pediatric Risk of Mortality III score was 16 (10-23). Majority of hemophagocytic lymphohistiocytosis was infection-associated (n = 51; 82.3%). Among these, scrub typhus accounted for 29% of cases (n = 18), dengue 17.7% (n = 11), bacterial sepsis 14.5% (n = 9), enteric fever 6.5% (n = 4), and other infections 14.5% (n = 9). Systemic-onset juvenile idiopathic arthritis accounted for 9.7% of cases (n = 6) and malignancy for 4.8% patients (n = 3). Majority of cases were treated with steroids (77.4%) and IV immunoglobulin (25.8%). Various complications noted were shock (71%), acute kidney injury (66.1%), acute respiratory distress syndrome (41.9%), disseminated intravascular coagulation (54.8%), CNS dysfunction (54.8%), multiple organ dysfunction syndrome (82.3%), and healthcare-associated infections (14.5%). Intensive care needs for primary illness and/or hemophagocytic lymphohistiocytosis included mechanical ventilation (74.2%); packed RBC (72.3%), fresh frozen plasma (40.3%), and platelet (48.4%) transfusion; vasoactive drugs (71%); and renal replacement therapy (24.2%). The median duration of PICU stay was 5 days (2.5-9.5 d) and mortality was 59.7% (n = 37). On univariate analysis, nonsurvivors had higher Pediatric Risk of Mortality III score; higher proportion of shock, acute kidney injury, acute respiratory distress syndrome, disseminated intravascular coagulation, and multiple organ dysfunction syndrome; the need for blood and blood components, mechanical ventilation, vasoactive drugs, and renal replacement therapy; higher Vasoactive-Inotropic Score; and prolonged duration of mechanical ventilation compared with survivors. CONCLUSIONS Hemophagocytic lymphohistiocytosis in PICU is commonly secondary to tropical infections and associated with high mortality. Higher severity of illness; shock and multiple organ dysfunction syndrome; need for blood and blood products, mechanical ventilation, vasoactive drugs, and renal replacement therapy; higher Vasoactive-Inotropic Score; and prolonged mechanical ventilation predicted death. Treatment of underlying infection and a less intense immunosuppressive therapy (steroids ± IV immunoglobulin) are suggested options. A high index of suspicion for complicating hemophagocytic lymphohistiocytosis is required in children with prolonged fever, cytopenias, organomegaly, and organ dysfunction not responding to conventional treatment.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a rare condition in children, with a high mortality rate of 41.99%. Often, due to the atypical presentation of HLH, the syndrome is difficult to diagnose. We report a case of an atypical presentation of HLH and the diagnostic dilemma that we faced. An 11-year-old boy was hospitalized with recurrent fever, hepatosplenomegaly, and worsening jaundice. Initial laboratory workup revealed an elevated prothrombin time (PT), high bilirubin, increased alanine transaminase (ALT), and positive Epstein Barr virus (EBV) deoxyribonucleic acid (DNA) polymerase chain reaction (PCR) and EBV immunoglobulin G (IgG). Based on our patient's presentation and initial laboratory findings, further extensive workup was done, which revealed cytopenias, hypofibrinogenemia, hemophagocytosis on biopsy, absent natural killer (NK) cell activity, high serum ferritin level, and high soluble CD25 (sIL-2 receptor); a diagnosis of HLH was made. He was started on broad-spectrum antibiotics, antivirals, antifungals, and cyclosporine. He became hypoxic and hypotensive and hence was intubated and started on vasopressors. However, his coagulation profile continued to deteriorate. He started bleeding from multiple sites and became unresponsive to ventilatory support, eventually dying as a result of complications of HLH. The ambiguous clinical presentation makes the diagnosis of this syndrome difficult. However, due to the high fatality rate, early recognition and prompt treatment are of utmost importance.

Abstract
Secondary hemophagocytic lymphohistiocytosis (hemophagocytic syndrome, massive macrophage activation syndrome) is a rare, aggressive, severe syndrome with a frequent fatal outcome. The pathogenesis of the syndrome, the role of viral infection, and the development of an excessive, aberrant, and inflammatory response leading to multiple organ dysfunction and sepsis remain unclear so far. The paper presents the data available in the literature and describes the authors' own observation of secondary hemophagocytic lymphohistiocytosis in a 14-year-old girl who had Epstein-Barr virus infection and died of severe multiple organ dysfunction. The in vivo diagnosis was based on the typical clinical presentations of the disease, the detection of the virus by a polymerase chain reaction assay, and the determination of blood ferritin levels. Contemporary morphological diagnostic criteria (immunohistochemical reactions with anti-EBV and anti-CD68 monoclonal antibodies; Epstein-Barr virus encoded RNA (EBER) in situ hybridization) are shown; and clinical and pathological comparisons have been made.

Abstract
Introduction: The mortality of coronavirus disease 2019 (COVID-19) is frequently driven by an injurious immune response characterized by the development of acute respiratory distress syndrome (ARDS), endotheliitis, coagulopathy, and multi-organ failure. This spectrum of hyperinflammation in COVID-19 is commonly referred to as cytokine storm syndrome (CSS). Areas covered: Medline and Google Scholar were searched up until 15th of August 2020 for relevant literature. Evidence supports a role of dysregulated immune responses in the immunopathogenesis of severe COVID-19. CSS associated with SARS-CoV-2 shows similarities to the exuberant cytokine production in some patients with viral infection (e.g.SARS-CoV-1) and may be confused with other syndromes of hyperinflammation like the cytokine release syndrome (CRS) in CAR-T cell therapy. Interleukin (IL)-6, IL-8, and tumor necrosis factor-alpha have emerged as predictors of COVID-19 severity and in-hospital mortality. Expert opinion: Despite similarities, COVID-19-CSS appears to be distinct from HLH, MAS, and CRS, and the application of HLH diagnostic scores and criteria to COVID-19 is not supported by emerging data. While immunosuppressive therapy with glucocorticoids has shown a mortality benefit, cytokine inhibitors may hold promise as 'rescue therapies' in severe COVID-19. Given the arguably limited benefit in advanced disease, strategies to prevent the development of COVID-19-CSS are needed.

Abstract
Coronavirus disease 2019 (COVID-19) continues to affect millions of people around the globe. As data emerge, it is becoming more evident that extrapulmonary organ involvement, particularly the kidneys, highly influence mortality. The incidence of acute kidney injury has been estimated to be 30% in COVID-19 non-survivors. Current evidence suggests four broad mechanisms of renal injury: Hypovolaemia, acute respiratory distress syndrome related, cytokine storm and direct viral invasion as seen on renal autopsy findings. We look to critically assess the epidemiology, pathophysiology and management of kidney injury in COVID-19.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a syndrome describing patients with severe systemic hyperinflammation. Characteristic features include unremitting fever, cytopenias, hepatosplenomegaly, and elevation of typical HLH biomarkers. Patients can develop hepatitis, coagulopathy, liver failure, central nervous system involvement, multiorgan failure, and other manifestations. The syndrome has a high mortality rate. More and more, it is recognized that while HLH can be appropriately used as a broad summary diagnosis, many pediatric patients actually suffer from an expanding spectrum of genetic diseases that can be complicated by the syndrome of HLH. Classic genetic diseases in which HLH is a typical and common manifestation include pathogenic changes in familial HLH genes (PRF1, UNC13D, STXBP2, and STX11), several granule/pigment abnormality genes (RAB27A, LYST, and AP3B1), X-linked lymphoproliferative disease genes (SH2D1A and XIAP), and others such as NLRC4, CDC42, and the Epstein-Barr virus susceptibility diseases. There are many other genetic diseases in which HLH is an infrequent complication of the disorder as opposed to a prominent manifestation of the disease caused directly by the genetic defect, including other primary immune deficiencies and inborn errors of metabolism. HLH can also occur in patients with underlying rheumatologic or autoinflammatory disorders and is usually designated macrophage activation syndrome in those settings. Additionally, HLH can develop in patients during infections or malignancies without a known (or as-yet-identified) genetic predisposition. This article will attempt to summarize current concepts in the pediatric HLH field as well as offer a practical diagnostic and treatment overview.

Abstract
INTRODUCTION Adult onset Still disease (AOSD) is a rare systemic inflammatory condition. The clinical spectrum of this disease ranges from self-limiting forms with mild symptoms to life-threatening cases. Glucocorticoids and non-steroidal anti-inflammatory drugs (NSAIDs) represent the first line of therapy for AOSD, with add-on therapy with second-line drug reserved to steroid-dependent patients and in life-threatening cases. Currently, early treatment with conventional disease modifying anti-rheumatic drugs (DMARDs) and biologic agents blocking causal cytokines is advocated in patients with severe and recalcitrant clinical manifestations. AREAS COVERED This review analyzes the available controlled evidence and observational data regarding the efficacy and safety of conventional and biological pharmacological agents in the treatment of AOSD. EXPERT OPINION Non-steroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids are effective in controlling clinical manifestations in the majority of AOSD patients. Conventional DMARDs can be 20 effective in some severe and steroid-dependent cases of AOSD; however, anti-cytokine agents represent an effective and overall more suitable alternative in this specific subset of patients. IL-1 and IL-6 blockade are effective in treating systemic and articular inflammation of AOSD patients. IL-1 blockade also has an excellent safety profile and therefore represent the first choice of biologic treatment in this clinical scenario.

Abstract
The outbreak of coronavirus disease 2019 (COVID-19) in December 2019 in Wuhan, China, introduced the third highly pathogenic coronavirus into humans in the 21st century. Scientific advance after the severe acute respiratory syndrome coronavirus (SARS-CoV) epidemic and Middle East respiratory syndrome coronavirus (MERS-CoV) emergence enabled clinicians to understand the epidemiology and pathophysiology of SARS-CoV-2. In this review, we summarize and discuss the epidemiology, clinical features, and virology of and host immune responses to SARS-CoV, MERS-CoV, and SARS-CoV-2 and the pathogenesis of coronavirus-induced acute respiratory distress syndrome (ARDS). We especially highlight that highly pathogenic coronaviruses might cause infection-associated hemophagocytic lymphohistiocytosis, which is involved in the immunopathogenesis of human coronavirus-induced ARDS, and also discuss the potential implication of hemophagocytic lymphohistiocytosis therapeutics for combating severe coronavirus infection.

Abstract
We report a large cohort of pediatric patients with human monocytic ehrlichiosis (HME), enabling an estimated incidence of secondary hemophagocytic lymphohistiocytosis (HLH) in hospitalized children with HME. Among 49 children with PCR-confirmed Ehrlichia infection, 8 (16%) met current criteria for HLH. Those with HLH had more significant hematologic abnormalities and longer durations from symptom onset to admission and definitive anti-infective therapy. Among these eight, three received chemotherapy plus doxycycline, one of whom died; the other five were treated with doxycycline without chemotherapy, and all survived without HLH recurrence. Our findings demonstrate that antimicrobial therapy alone can successfully resolve Ehrlichia-associated HLH.

Abstract
We describe a case of haemophagocytic lymphohistiocytosis (HLH) secondary to disseminated histoplasmosis, which was treated with chemotherapy in addition to standard antifungal therapy. While HLH in the setting of infections is very well described, its treatment in this setting is controversial, with some physicians treating only the underlying infection, whereas others using immune suppression in addition to antimicrobials. To the best of our knowledge, this is the first report documenting the successful treatment of an adult patient with HLH due to disseminated histoplasmosis using etoposide chemotherapy after initial antifungal therapy failed to show improvement.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a rare condition characterized by an overwhelming inflammatory cascade activation which is often associated with rapid progression and high mortality. It may be familial with an underlying genetic mutation or triggered by infection, malignancy, and autoimmune disease. Disseminated histoplasmosis caused by histoplasma capsulatum is a granulomatous fungal disease seen typically in immunocompromised patients with varied clinical manifestations and requires long-term antifungal therapy. We present the case of a 61-year-old immunocompromised female with significant travel history who came with fever, pancytopenia, and liver failure raising suspicion for HLH that prompted a bone marrow biopsy procedure. Hemophagocytic figures consistent with HLH and numerous encapsulated fungi resembling histoplasma were visualized. She was treated with intravenous (IV) liposomal amphotericin B. Etoposide chemotherapy and interleukin-1 (IL-1) antagonist anakinra were deferred in order to limit her immunosuppression, and treatment was focused on antifungal therapy.

Abstract
BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome that predominantly affects infants from birth to 18 months of age, characterized by fever and multiorgan failure. Liver injury has been rarely reported as a presenting sign in the neonatal period. This study reports a case with HLH in the neonatal period who presented with acute liver failure. CASE PRESENTATION Herein, a 3-day-old female newborn was admitted with cytopenia, increased liver enzymes, hypofibrinogenemia, and markedly elevated serum ferritin. Hemophagocytosis of bone marrow biopsy confirmed the diagnosis of HLH. The newborn was treated with HLH-2004 protocol, but she finally died from multiorgan failure. CONCLUSION Growing awareness of HLH as a cause of liver failure in the neonatal period can be associated with early treatment and reduces mortality in this group of patients.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a rare but severe form of immune dysregulation often presenting as unremitting fever, cytopenia, hepatosplenomegaly, coagulopathy, and elevation of typical HLH biomarkers. HLH is universally fatal, if left untreated. The HLH-2004 criteria are widely used to diagnose this condition, but there is growing concerns across different settings that its application may result in undertreatment of certain patients. There is an expanding spectrum of genetic conditions that can be complicated by HLH. This review summarizes the current concepts in HLH, the lessons learned from the past, and provide an overview of the latest diagnostic and treatment modalities.

Abstract
This study aimed to examine the association between low T3 syndrome and overall survival (OS) in patients with secondary hemophagocytic lymphohistiocytosis (sHLH). The study consisted of 111 consecutive patients hospitalized due to newly diagnosed sHLH with detailed thyroid hormone profiles on admission. Low T3 syndrome was found in 75.7% of the studied sHLH population. After a median follow-up of 83 (interquartile range 25-365) days, there were 60 (71.4%) cumulative deaths in the low T3 syndrome group and 13 (48.1%) in the euthyroid group. Survival analysis showed a lower survival probability for patients with low FT3 than for those with normal FT3 (median OS, 60 vs. 365 days, p = .011). In the multivariate analysis, low T3 syndrome was an independent prognostic factor for OS (HR = 2.474; 95% CI 1.351-4.532, p = .003). Low T3 syndrome is frequently found and associated with worse outcomes in patients with sHLH.

Abstract
INTRODUCTION Visceral leishmaniasis (VL) is an ill-studied disease that is endemic to several regions of Brazil. It is often complicated by hemophagocytic lymphohistiocytosis (HLH), a potentially fatal disorder resulting from excessive non-malignant activation/proliferation of T lymphocytes and macrophages. Considering the overlapping clinical and laboratory characteristics of these diseases, diagnosing HLH is a challenge. Therefore, tracking the association between VL and HLH is necessary in endemic areas. Although HLH can be inapparent and resolve with antileishmanicides, this may not always occur. HLH causes high lethality; therefore, immunosuppressive therapy should be instituted immediately in order to avoid a fatal outcome. METHODS: We described the epidemiological, clinical, laboratory, and therapeutic profile of this association in a region of Brazil endemic for VL. RESULTS We presented 39 patients with this association in a retrospective cohort of 258 children who were admitted from January 2012 to June 2017. Of the 39 patients, 31 were from urban areas (79.5%), and 21 (53%) were males. The mean age and weight were 2.86 (2.08) years and 14.03 (5.96) kg, respectively. The main symptoms were fever (100%), hepatosplenomegaly (100%), pallor of the skin and mucosa (82.5%), edema (38.5%), bleeding (25%), and jaundice (7.5%). Hemophagocytosis was identified in 16/37 (43.24%) patients, and direct examination revealed that 26/37 (70.27%) patients were positive for VL. The patients were treated as recommended by the Ministry of Health. CONCLUSIONS It was observed that HLH is a common complication in endemic areas, and its diagnosis must consider the overlapping of clinical characteristics and pancytopenia.

Abstract
Objectives Hemophagocytic syndrome (HPS) is characterized by various clinical and biological data derived from cytokine hyperproduction and cell proliferation. The objectives of this study were to evaluate the epidemiological, etiological, clinical and evolutionary characteristics of patients diagnosed with hemophagocytic syndrome and HIV infection, as well as their comparison with data from the literature. Methods- A retrospective descriptive observational study was performed, including all adult patients with a diagnosis of HPS and HIV infection treated in the Infectious Diseases and Tropical Medicine Unit of the Hospital Universitario Insular, Las Palmas, Gran Canaria from June 1, 1998 to December 31, 2018. Results An analysis of this series of case reports of 15 patients showed a higher percentage of males than females, with a mean age of 42 years. With respect to the diagnostic criteria for HPS, presence of fever, cytopenias and hyperferritinemia were a constant in all patients. Clinical neurological manifestations were frequent and clinical respiratory signs and symptoms absent. HPS was confirmed in some patients who were not severely immune-depressed and had undetectable viral loads. Furthermore, 40% of cases were not receiving ART. The most frequent triggering causes of HPS were viral, especially HHV-8. In addition, two new HPS triggers were identified: Blastocystis dermatitidis and Mycobacterium chelonae. Conclusion Administration of treatment in HPS is arbitrary. This, together with the high mortality rate and the fact that it is underdiagnosed, indicates the importance of conducting future studies.
