A significant proportion of COVID-19 patients show evidence of hyperinflammation (HI), of which secondary haemophagocytic lymphohistiocytosis (sHLH) is the most severe manifestation and diagnosed with HScore. Using a COVID-relevant modification of the HScore (%HScore), we set out to determine the prevalence of sHLH in 567 COVID-19 inpatient cases.The overall incidence of individuals with an 80% probability of sHLH in our COVID-19 cohort was 1.59% on admission and only rose to 4.05% if calculated at any time during admission. This small cohort as defined by %HScore showed no excess mortality compared with the whole cohort. Overall, %HScores were lower in older patients (p<0.0001) and did not reliably predict outcome at any cut-off value (AUROC 0.533, p=0.211, odds ratio 0.99).Our study demonstrates that a modified version (%HScore) of the conventional sHLH scoring system (HScore) does not enable risk stratification in people hospitalised with COVID. We propose further work is needed to develop novel approaches to predict HI and improve trial stratification for HI directed therapy in people with COVID-19.

Secondary hemophagocytic lymphohistiocytosis (HLH) syndrome, a fatal disorder characterized by NK/T-cell deficiency, cytokine storm, and organ damage, is rare in chronic lymphocytic leukemia (CLL). Ibrutinib, the first generation of irreversible Bruton's tyrosine kinase inhibitor, has been the first-line therapy for CLL. As an off-target effect, it can also block IL-2 inducible T-cell kinase (ITK), which is essential in maintaining normal NK and T-cell functions.

This case report presents the management of a 25-year-old woman with refractory hemophagocytic lymphohistiocytosis (HLH) secondary to adult-onset Still's disease. Despite initial treatment with corticosteroids and biologic therapies, including anakinra and tocilizumab, her condition continued to deteriorate, necessitating intensive care unit admission. Following multidisciplinary consultation, ruxolitinib therapy, a Janus kinase (JAK) inhibitor targeting hyperinflammation, was initiated.

Background: This study aimed to identify specific biomarkers in oncology patients experiencing immune-related cytokine release syndrome (irCRS)-like symptoms during immune checkpoint inhibitor (ICI) therapy, including severe cases like hemophagocytic lymphohistiocytosis (irHLH), and to distinguish these from sepsis. A secondary objective was to retrospectively analyze the efficacy of tocilizumab (TCZ) in treating corticosteroid (CS)-refractory high-grade irCRS.
Patients And Methods: A cohort of 35 patients presenting with irCRS-like symptoms was studied, including 9 with irHLH-like manifestations and 8 with sepsis.

X-linked lymphoproliferative disease (XLP) is a rare primary immunodeficiency with susceptibility and vulnerability to Epstein-Barr virus (EBV) infection. Most patients were diagnosed in early childhood and do not survive into adulthood. Here we reported an adult-onset XLP patient presenting with fever, dyspnea, and pulmonary nodules, mimicking respiratory infection at disease onset.

A risk-stratified treatment approach to MCD based on Rituximab immunotherapy for mild cases and chemo-immunotherapy for severe cases has been shown to yield excellent outcomes in PLWH. In contrast, HLH disease, previously known as secondary HLH, has a dismal prognosis even when promptly treated according to guidelines.
