Chris Bailey, Claire Dearden, Kirit Ardeshna
Haemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening syndrome characterised by defective cytotoxic function and hypercytokinaemia leading to macrophage expansion and haemophagocytosis. Patients often present with unexplained fevers, hepatosplenomegaly and pancytopenia, with elevation in serum ferritin and triglyceride. Acquired forms are triggered by infection, malignancy or rheumatological disorders. HLH in the setting of chronic lymphocytic leukaemia is rarely reported, however, and is usually associated with infection or as a consequence of chemotherapy...

CASE REPORT: A male Domestic Short-hair cat was presented for chronic weight loss, lethargy and hyporexia. Complete haematological examination revealed non-regenerative anaemia, neutropenia and thrombocytopenia, as well as Howell-Jolly bodies, anisocytosis, polychromasia and macrocytosis on blood smear evaluation. Histopathological evaluation of bone marrow biopsy disclosed hypocellularity consistent with bone marrow failure. Concurrent hypocobalaminaemia was identified and treated with parenteral cyanocobalamin supplementation...

Temozolomide may cause thrombocytopenia or neutropenia in 3-4% of glioblastoma patients, respectively. However, pancytopenia is rarely reported. MGMT (O6-methylguanine-DNA-methyltransferase) enzyme repairs temozolomide-induced DNA mutations and associates both with antitumour efficacy and myelosuppression. Many studies on the effects of MGMT gene-methylation on temozolomide's effects exist, but much fewer publications concerning MGMT variants were documented. A full sequencing of the MGMT gene was performed in a female glioblastoma patient, who developed pancytopenia following temozolomide treatment...

OBJECTIVE: To investigate the potential efficacy of panaxadiol saponins component (PDS-C), a biologically active fraction isolated from total ginsenosides, to reverse chemotherapy-induced myelosuppression and pancytopenia caused by cyclophamide (CTX). METHODS: Mice with myelosuppression induced by CTX were treated with PDS-C at a low- (20 mg/kg), moderate- (40 mg/kg), or high-dose (80 mg/kg) for 7 consecutive days. The level of peripheral white blood cell (WBC), neutrophil (NEU) and platelet (PLT) were measured, the histopathology and colony formation were observed, the protein kinase and transcription factors in hematopoietic cells were determined by immunohistochemical staining and Western blot...

BACKGROUND: Myelophthisis due to melanoma is a rare phenomenon. Treatment strategies for patients with this serious complication of malignancy have not been well documented, and none have previously reported efficacy of immune checkpoint inhibition. Since bone metastases are not measurable lesions per standard response criteria, the efficacy of immune checkpoint inhibition in the bones is also not well described. CASE PRESENTATION: We describe a patient with widespread melanoma metastases involving the bone marrow causing myelophthisis and pancytopenia who responded to immune checkpoint inhibition with the anti-programmed cell death-1 (PD-1) inhibitor pembrolizumab...

We report a case of expanded dengue syndrome, where three uncommon presentations occurred concomitantly. A patient with dengue haemorrhagic fever presented initially with acute acalculous cholecystitis along with acute pancreatitis, but later on, during resolution of pancreatitis and cholecystitis, developed pancytopenia, most likely due to haemophagocytic syndrome. Such presentations, besides being rare themselves, have not been reported to occur concomitantly, in the same patient, during the same disease process...

Natalizumab is a monoclonal antibody indicated for the treatment of patients with relapsing-remitting multiple sclerosis. Its use is prohibited during pregnancy. However, natalizumab exposures throughout the gestation period or during the third trimester, because of intense disease activity, are possible and begin to be reported. There are enough reassuring arguments against a teratogenicity, through pregnancy registries; but deleterious effects in the monitoring of newborn, are not well known. A disorder of hematopoiesis is possible with anemia, thrombocytopenia or pancytopenia, as discussed by the author through an observation...

Two children with congenital heart disease status post surgical correction presented with prolonged constitutional symptoms, hepatosplenomegaly and pancytopenia. Concern for malignancy prompted bone marrow biopsies that were without evidence thereof. In case 1, echocardiography identified a multilobulated vegetation on the conduit valve. In case 2, transthoracic, transesophageal and intracardiac echocardiography were performed and were without evidence of cardiac vegetations; however, pulmonic emboli raised concern for infective endocarditis...

Hypocellular acute myeloid leukemia (AML) mainly occurs in elderly patients, and is extremely rare in childhood. There is still no established treatment for hypocellular AML. We report the case of an 11-year-old boy with hypocellular AML who was treated successfully with allogenic bone marrow transplantation (allo-BMT). He presented with fever, pallor and pancytopenia. Bone marrow aspiration and biopsy confirmed a diagnosis of hypocellular AML. Although low-dose cytarabine induced reduction of blasts, it did not lead to complete remission...

Bortezomib has been shown to be effective and well-tolerated in patients with refractory acute lymphoblastic leukemia (ALL) in the Therapeutic Advances in Childhood Leukemia trial. However, the safety and efficacy of bortezomib have not been evaluated in Japanese pediatric patients. Here, we report the results of a clinical trial designed to evaluate the safety of bortezomib combined with induction chemotherapy in Japanese children with refractory ALL. A total of six patients with B-precursor ALL were enrolled in this study...

We report the first two cases of post-transplant lymphoproliferative disorder (PTLD) in recipients of islet transplants worldwide. First, a 44-year old recipient of 3 islet infusions developed PTLD 80 months after his initial transplant, presenting with abdominal pain and diffuse terminal ileum thickening on imaging. He was treated with surgical excision, reduction of immunosuppression and rituximab. Seven months later he developed central nervous system PTLD, presenting with vertigo and diplopia; immunosuppression was discontinued, resulting in graft loss, and he was given high-dose methotrexate and consolidative autologous stem cell transplant...

Unlike clozapine, and despite its structural similarities, olanzapine is not usually associated with haematological suppression. Nonetheless this case report highlights an incident of olanzapine-induced thrombocytopenia and neutropenia in a first-contact patient. We report on a 50-year-old male who presented with 7 years of delusions and hallucinations. A diagnosis of schizophrenia was made in the absence of any suggestive features of mood disorders, substance abuse or organicity, and olanzapine as second-line treatment...

A 48-year-old man with hepatitis C virus (HCV) cirrhosis complicated by hepatocellular carcinoma underwent liver transplantation. His course was complicated by fever, diarrhea, abdominal pain, and pancytopenia. He developed a diffuse erythematous rash, which progressed to erythroderma. Biopsies of the colon and skin were consistent with acute graft-versus-host disease. Donor-derived lymphocytes were present in the peripheral blood. The patient was treated with corticosteroids and cyclosporine; however, he had minimal response to intensive immunosuppressive therapy...

Background Elevated liver values are the most common pathological laboratory result in Germany. Frequent findings, especially in younger patients, are nutritive- or medicamentous- toxic reasons, viral or autoimmune hepatitis. A macrophage activation syndrome (MAS) may manifest like a viral infectious disease with fever, hepatosplenomegaly and pancytopenia and is associated with a high mortality. It is based on an enhanced activation of macrophages with increased cytokine release, leading to organ damage and multi-organ failure...
