Acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first identified in Wuhan, China; and spread all over the world. Reverse-transcription polymerase chain reaction (RT-PCR) test for SARS-CoV-2 usually returns to negative 20 days post-infection, but prolonged positivity has been reported up 63 days. A case whose viral shedding lasted 60 is from China. Herein we report a patient with history of autologous stem cell transplantation (ASCT) lymphoma RT-PCR remained positive 74 The positivity,...

As in the case of cancer, risk infection increases when host's immune system is not working properly. It has been shown that toxins produced by bacteria responsible for bacterial infections can alter properties cancer cells as well their sensitivity to chemotherapy agents. Staphylococcus aureus (S. aureus) one most prevalent pathogens acute myeloid leukemia (AML) patients and it produces several virulence factors, including Staphylococcal enterotoxin A (SEA) B (SEB). Cytotoxicity, transwell...

There is yet insufficient information about the effects of HSCT on clinical course In present study, we aimed to investigate COVID-19 in patients who had undergone HSCT. Materials and methods: We analyzed baseline characteristics, findings COVID-19, hospitalization death rates, overall survival, case fatality rates recipients diagnosed with retrospectively. Results: 57.6% underwent AHSCT, 42.4% allo-HSCT. 60.6%, 27.3%,...

The SARS-CoV-2 spike protein mRNA-based vaccines have prevented countless mortality and morbidity, an excellent risk/benefit ratio. However, various adverse events may rarely occur after the BNT162b2 vaccine, like any other medical intervention. COVID-19 itself produced endogenously by mRNA immunological, microenvironmental, prothrombotic, neoplastic effects. As a contribution to published report, we would share our experience regarding four cases in which myeloid neoplasms emerged following...

Tyrosine kinase inhibitors (TKis) and Bruton's TKi (BTKis) constitute broadly used antitumor drug groups with almost completely tolerable manageable side-effect profiles. Mainly side effects are cardiovascular gastrointestinal for the group. Hypophosphatemia is documented frequently in many studies TKis but rarely mentioned ibrutinib use up to present.A 61-year-old patient diagnosis of chronic lymphocytic leukemia had hypophosphatemia-related complaints symptoms when was preferred his second...
