Project description:BackgroundMycobacterium iranicum has recently been recognised as an opportunistic human pathogen. Although infectious conditions represent frequent triggers for hemophagocytic lymphohistiocytosis, non-tuberculous mycobacterial infections are rarely associated with this entity. To this date, M. iranicum infection has never been reported in France, has never been associated with hemophagocytic lymphohistiocytosis and has never been found to be multi-resistant on standardized antimicrobial susceptibility testing.Case presentationWe report a case of a French Caucasian man with secondary hemophagocytic lymphohistiocytosis in the context of M. iranicum bacteraemia and Hodgkin's disease. We review available data concerning M. iranicum antimycobacterial susceptibility testing and treatment outcomes. We also review the association between hemophagocytic lymphohistiocytosis and non-tuberculous mycobacterial infections.ConclusionInterpretation of M. iranicum positive cultures remains a clinical challenge and non-tuberculous mycobacterial infections need to be considered in secondary hemophagocytic lymphohistiocytosis differential diagnosis.

Project description:Hemophagocytic lymphohistiocytosis (HLH) is rare and life threatening syndrome. There are only a few reported cases of HLH with GI symptoms. We describe the case of an 18 months old boy who presented with a history of fever for 40 days, abdominal distention and hepatosplenomegaly. Abdominal x-ray showed a pneumoperitoneum. Urgent laparotomy was done which revealed an isolated cecal perforation. The histopathological findings in the subsequent resected bowel was HLH with evidence of positive EBV Barr infection.

Project description:Hemophagocytic lymphohistiocytosis (HLH) is a systemic inflammation disorder secondary to immune dysregulation. Patients may present with fevers, splenomegaly, bone marrow failure and hemophagocytosis, among other clinical and laboratory findings. Lymphoma-associated HLH (LA-HLH) is a puzzling diagnosis given both conditions overlapping presentation. There are currently no established treatment guidelines for LA-HLH. We conducted a retrospective search of the tumor registry and pathology database at the University of Miami/Jackson Memorial Hospital using Pathology Laboratory Information System (LIS) and natural language search. We identified adult patients with a combined diagnosis of lymphoma and HLH between January 2008 and July 2018. Data from nine LA-HLH patients were identified and reviewed. The median age was 53 years (range 19 - 73), with 78% of cases of Hispanic origin. Lymphoma subtypes consisted of six T-cell/NK-cell neoplasms: two peripheral T-cell lymphoma (PTCL), not otherwise specified (NOS); two Epstein-Barr virus (EBV)+ extranodal NK-/T-cell lymphomas; one EBV+, CD8+, PTCL, NOS; one EBV+, post-transplant lymphoproliferative disorder-anaplastic large cell lymphoma, anaplastic lymphoma kinase negative (PTLD ALCL ALK-); and three B-cell neoplasms: one EBV+ diffuse large B-cell lymphoma (DLBCL); two DLBCL, NOS. HLH and lymphoma were diagnosed simultaneously in six out of nine cases. Hemophagocytosis phenomena were demonstrated in seven out of nine cases. Treatment consisted of combined HLH and lymphoma therapies in four cases, while lymphoma-directed therapy was applied to four patients; another case was treated with a modified version of the HLH-1994 protocol. Overall, a total of five cases were exposed to HLH-directed regimens (HLH-1994/2004). Three patients had refractory LA-HLH and entered hospice care, whereas another three cases succumbed to treatment-related complications. Of the seven cases that were evaluable for lymphoma response, four cases (57%) achieved complete response (CR), and three of them (43%) were alive with no evidence of recurrence at 10, 16 and 52 months as of the last contact. Herein, we describe our unique experience of an LA-HLH case series in a predominantly Hispanic population in South Florida. The diagnosis is challenging, often delayed, and the prognosis is dismal in refractory cases despite currently available rescue therapies. Furthermore, we describe for the first time the association between HLH and PTLD ALCL.

Project description:Angioimmunoblastic T cell lymphoma (AITL)-associated hemophagocytic lymphohistiocytosis (HLH) rarely occurs with annular erythema multiforme-like rashes. The present case report describes a patient who was misdiagnosed with erythema multiforme at an early stage of the disease due to annular erythema multiforme-like eruptions. However, antihistamine treatment was ineffective. The patient progressed rapidly with high fever, hepatosplenomegaly and pharyngitis. The number of copies of Epstein-Barr virus DNA continuously increased. Accompanied by the swelling of lymph nodes, the blood cell count decreased. Further bone-marrow examination and biopsy of the lymph nodes were conducted. The patient was eventually diagnosed with AITL-associated HLH, and treated with etoposide together with cyclophosphamide, doxorubicin, vincristine and prednisolone. The patient was successfully treated with several courses of chemotherapy. In view of the fact that AITL-associated HLH with annular erythema multiforme-like rashes is relatively rare worldwide and is associated with a high mortality rate, the data on previous cases were reviewed with the hope of providing clinical bases for early diagnosis and treatment of AITL-associated HLH.

Project description:BackgroundHemophagocytic lymfohistiocytosis (HLH) is a rare, life-threatening hyperinflammation, characterized by immune system over-activation resulting in hemophagocytosis. HLH could appear as a primary disease caused by mutations of immune-regulatory genes, or develop as a result of viral or bacterial infections, or malignancy. Congenital factor VII (FVII) deficiency is a rare autosomal recessive disorder characterized by prolonged prothrombin time (PT) and low FVII, which may increase bleeding risk.Case presentationA 50-year-old woman was admitted for a fever persisted for 20 days, presenting with cytopenia, high hyperferritinemia, low activity of NK cells. Bone marrow aspiration showed hemophagocytosis. CT scanning found pulmonary infection. EBV and CMV were not detected. Genetic scanning did not find pathogenic mutation of a HLH NGS panel including 26 genes. This patient was treated as recommended by the HLH 2004 Guidelines. Coagulation tests identified FVII deficiency. Genetic analysis of F7 gene in the patient and her family members identified recurrent compound heterozygous F7 c.64 + 5G > A and c.1224 T > G (p.His408Gln) mutations in this patient and her brother who showed postoperative hemorrhage after surgical resection of renal cell carcinoma. Heterozygotes in this family were asymptomatic.ConclusionsTo our knowledge, this is the first report of HLH in combination with congenital FVII deficiency in Chinese population.

Project description:BackgroundHemophagocytic lymphohistiocytosis (HLH) is a severe disorder characterized by excessive activation of the immune system, leading to hypercytokinemia and damage to multiple organs. We report a rare case of HLH with myopericarditis caused by Campylobacter infection.Case presentationA 28-year-old male patient with a history of hypertension without medicine control presented at the hospital after a four-day fever, decreasing urine amount, rashes on his trunk and limbs, and other symptoms. He was admitted with a provisional diagnosis of atypical infection and allergic skin rash related to diclofenac. However, his condition deteriorated, and he developed shock, tachycardia, chest distress, and bilateral pleural effusion after admission. Further investigations revealed cardiogenic shock related to myopericarditis, and he was transferred to the ICU. In addition, a stool PCR panel subsequently revealed a positive result for Campylobacter. On day 6, he was diagnosed with HLH. Under Clarithromycin and dexamethasone infusion, leukocytosis, anemia and thrombocytopenia with cardiogenic shock status improved. Then, he was later discharged in stable condition.ConclusionsHLH and myopericarditis caused by Campylobacter are very rare. Early detection of Campylobacter-induced HLH and multiple organ failure, as well as prompt use of antibiotics and immunosuppressants, can be helpful for prognosis.

Project description:Adult hemophagocytic lymphohistiocytosis is a secondary immunopathologic phenomenon, mainly secondary to malignancy, infection, or autoimmune disorders. The performance of diagnostic criteria, studied in the pediatric population, is yet to be validated in the adult population. Some of the criteria include cytopenias and organomegaly that are inherent features to malignant processes, thus making the diagnosis of hemophagocytic lymphohistiocytosis a challenge in patients with cancer.We describe the case of a 54-year-old white man with history of metastatic maxillary sinus adenoid cystic carcinoma who had severe liver injury and cytopenias with progressive clinical deterioration. We performed an evaluation, by flow cytometry, of the expression of surface markers in his natural killer cells that revealed remarkable abnormalities. His syndrome eventually fulfilled criteria for hemophagocytic lymphohistiocytosis and he received therapy with steroids with interval clinical improvement. Unfortunately, he refused further cytotoxic treatment and died 2 weeks later.The conventional criteria for the diagnosis of hemophagocytic lymphohistiocytosis are suboptimal for adult patients with cancer resulting in delays in diagnosis and timely initiation of treatment. The diagnostic criteria have to be re-evaluated in patients with cancer; novel, easily available, and accurate diagnostic methods are needed.

Project description:Hemophagocytic lymphohistiocytosis is a disease process characterized by unregulated hyperactivation of the immune system associated with multiorgan involvement and high mortality rates. Early recognition is crucial and a recently validated diagnostic schema, the H-Score, may facilitate diagnosis particularly in secondary hemophagocytic lymphohistiocytosis cases. We present a patient with secondary hemophagocytic lymphohistiocytosis in association with metastatic renal cell carcinoma in whom high-dose steroid therapy induced a remarkable response.A 35-year-old Vietnamese man with quiescent systemic lupus erythematosus was diagnosed 5 months prior to admission with left-sided renal cell carcinoma metastatic to the pancreas and spine. Ten days prior to admission, a febrile illness (temperatures to 39 °C) associated with flu-like symptoms unresponsive to levofloxacin developed. He took only two doses of pazopanib prior to admission. High fevers unresponsive to antimicrobial therapy, cytopenias, disseminated intravascular coagulation, and progressive multiorgan failure led to intubation and intensive care unit stay. Extensive infectious disease workup showed only negative results, but elevation of interleukin-2 receptor, exceedingly high ferritin levels and other features earned an H-Score of 302, consistent with >99% diagnostic probability for secondary hemophagocytic lymphohistiocytosis. High-dose steroid therapy produced a rapid clinical and biochemical response.Hemophagocytic lymphohistiocytosis is a life-threatening disorder which is likely to be under-recognized. Increased awareness of this disease entity and its diagnosis is crucial toward early recognition and treatment. To our knowledge, our patient is only the second reported with secondary hemophagocytic lymphohistiocytosis occurring in the setting of renal cell carcinoma.

Project description:To investigate the potential treatment evolution and outcome improvement, we retrospectively compared clinical characteristics, therapeutic strategies, treatment responses, and overall survival (OS) in patients diagnosed and treated with lymphoma-associated HLH between 2004-2012 (n = 30) and 2013-2021 (n = 26). Our study showed that the clinical characteristics of lymphoma-associated HLH did not substantially change over the past two decades. However, more patients diagnosed in 2013-2021 were tested for Epstein-Barr virus than those diagnosed in 2004-2012 (69.3% vs. 33.3%; p = 0.021). In addition, Eastern Cooperative Oncology Group performance status 3-4 (hazard ratio (HR): 5.38; 95% confidence intervals (CI): 2.49-11.61; p < 0.001) and jaundice (HR: 2.91; 95% CI: 1.37-6.18; p = 0.006) were poor prognostic factors for lymphoma-associated HLH. With a comparable response rate of lymphoma treatment, patients treated in 2013-2021 had a numerically greater median OS than those treated in 2004-2012 (23.6 ± 19.8 vs. 9.7 ± 4.5 months). However, the difference was not statistically significant (p = 0.334). In conclusion, early diagnosis and tailored treatments that balance efficacy and adverse events remain the key to obtaining a better outcome in lymphoma-associated HLH.
