    Abstract Bone marrow studies currently provide a lot of valuable information in the diagnostics of hematological diseases including hematopoietic stem cells disorders. Our studies on low-molecular weight organic compounds in bone marrow stem cell niche in various pathogenic conditions, revealed relatively high variability of histamine levels in different groups of hematological diseases. It was also found that serotonin levels were significantly lower than those typically measured in peripheral blood as well as many have the influence on stem cells proliferative potential. This paper presents findings from quantitative and statistical analyses of histamine and serotonin levels. Bone marrow collected from patients undergoing routine diagnostic procedures for hematological diseases and receiving inpatient treatment were analyzed. Histamine and serotonin levels were measured using hydrophilic interaction liquid chromatography (HILIC) coupled with tandem mass spectrometry. Obtained data were analyzed statistically and correlated with the diagnosed groups of hematological diseases and the parameters of complete blood counts. Histamine was found in all tested samples, including those from patients without malignancy, and the reported levels were comparable to the reference values in blood. This observation allows us to assume that bone marrow cells can produce and accumulate histamine. Moreover, the statistical analysis revealed a significant relationship between histamine levels and diagnosed mastocytosis, and between histamine levels and myeloproliferative neoplasms. Different results were obtained for serotonin, and its concentrations in most cases were below the limit of quantification of the method used (< 0.2 ng/mL), which can only be compared to peripheral blood plasma. In a few cases, significantly higher serotonin levels were observed and it concerned diseases associated with an increased number of megakaryocytes in the bone marrow.

    Abstract Nodular regenerative liver hyperplasia (NRH) is a very rare but potentially severe complication of thiopurine-containing immunosuppressive therapy for autoimmune disorders, organ transplantation, and/or oncological treatment. Here we report a case of a 40-year-old female patient with Crohn's disease and genetic hypercoagulability disorder-factor V Leiden, who in the course of azathioprine immunosuppressive treatment for inflammatory bowel disease developed NRH, which was clinically manifested by thrombocytopenia and delicate hepato-splenomegaly. Moreover, her endoscopic examination of upper gastrointestinal tract demonstrated esophageal varices. Genetic analysis revealed heterozygous genotype (*1/*3A) of thiopurine S-methyltransferase (TPMT), a key enzyme of thiopurines' metabolism, which results in lower activity of TPMT enzyme, thereby making our patient more susceptible to azathioprine-related hepato and myelotoxicity development. Treatment was started with the immediate cessation of azathioprine therapy, and administration of propranolol as primary prophylaxis for bleeding from esophageal varices. Currently (3 years after diagnosis) remission of Crohn's disease is achieved, however, progression of features of portal hypertension is observed. Propranolol administration is continued and the patient is constantly monitored in our Department. Our Case Study highlights the clinical difficulties and challenges associated with diagnosing of azathioprine-induced NRH, as well as, supports previous observations that hypercoagulability disorders and abnormal TPMT activity may contribute to NRH development.

    Title translation Ectopic pancreas mimicking advanced gastric malignancy--case report.
    Abstract Ectopic pancreas is the most common type of ectopic tissue in gastrointestinal tract. It is typically asymptomatic, presenting as a small submucosal lesion in prepyloric region of stomach. The diagnosis is usually incidental, during gastroscopy. The patient with symptomatic heterotropic pancreas, mimicking gastric malignancy was described.
