: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease associated with immune system hyperactivation and the appearance of serious systemic disturbances. The purpose of this study was an assessment of natural killer (NK) cell disturbances in a group of children with clinical signs of HLH. A total of 43 children with HLH and 17 healthy children were enrolled in the study. NK phenotyping, intracellular perforin staining, and cytotoxicity tests were performed by using the flow cyt...

AbstractIntroduction: Autoimmune diseases, such as celiac disease (CD) and diabetes mellitus type 1, tend to co-occur within the same patient. The prevalence of CD in diabetic children is higher than in the general population, and is estimated to be 0.6–16.4%. The diagnosis of CD is based on histopathological examination and serological testing, however, these methods are still imperfect and new diagnostic algorithms should be considered.Aim: The aim of the study was to assess the diagnostic val...

Abstract Background Transfusion of blood-derived products is often used as a life-saving treatment, and being a blood donor should be common, especially among medical professionals. Thus, an awareness of one’s own blood type in medical students should be common. Our aim was to assess if students of the Medical University of Warsaw know their blood type and how many of them are registered blood donors. Material and methods A survey was conducted in a group of 1121 students. The survey included qu...
Cytokines are a large group of small proteins which play a significant role in cell signaling and regulate a variety of processes in organisms, including proliferation and differentiation of many cells, mediation in defense reactions and regulation of hematopoiesis. Cytokines can be divided into those with pro- and those with anti-inflammatory properties. In the group of pro-inflammatory cytokines the most important are: IL-1 beta, IL-6, TNF-alpha, and IFN-gamma. Pro-inflammatory cytokines might...
Abstract The identification of the new form of hemoglobin in fetus red blood cells (HbF), different from adult hemoglobin (HbA), was made over one hundred years ago. Since this time, various methods of fetal hemoglobin measurement have been designed. Most of them are based on the different biochemical characteristics of HbF. Fetal hemoglobin's affinity for oxygen is substantially greater than that of adult hemoglobin. The first techniques for the determination of fetal hemoglobin were based on i...
: Idiopathic nephrotic syndrome (INS) is a common chronic illness characterized by massive proteinuria and hypo-albuminemia in children. Baseline treatment is 6 month-corticotherapy. In cases of steroid resistant/dependent INS several types of treatment are used, including course of methyloprednisolone "pulses", alkylating agents, cyclosporin A, levamisole and mycophenolate mofetil. It has been suggested that children with frequently relapsing nephrotic syndrome or steroid-dependent nephrotic sy...

We describe the case of a boy with acute myeloid leukemia with translocation t(6;11)(p22.2;q23) and insertion ins(11;9)(q23;p21.3p21.3). Translocation t(6;11)(p22.2;q23) involving the short arm of chromosome 6 has not been previously described. The LDI-PCR showed the presence of KMT2A-MLLT3 fusion and identified the BTN3A1 (butyrophilin subfamily 3 member A1) gene on 6p22.2 as the other KMT2A translocation partner. The BTN3A1 gene has never been described in the context of acute leukemia. Althou...

Hemophagocytic lymphohistiocytosis (HLH) is a severe systemic syndrome associated with hyperactivation of macrophages and impaired regulation of the immune system. Two forms of HLH are currently recognized: genetically determined or familial (FHLH), and secondarily developed in the course of primary diseases, like autoimmune disorders, rheumatoid disorders, cancers, or infections. In the Polish population, FHLH is rather rare. The aim of the present study was to assess the immune function in a g...

Paediatric respiratory tract infections are among the most common reasons for preschool and school absences and visits to physicians. The disease mainly involves the upper respiratory tract and is associated with fever, cough, sore throat, and running nose. Children with recurrent respiratory infections (RRI), which are defined as more than six serious diseases a year, are a difficult diagnostic challenge. The aim of this study was to assess immunological deviations in laboratory tests performed...
