Allogeneic Hematopoietic Stem Cell Transplantation Despite Severe Infection in a Lung Transplanted Patient-A Case Report.

Solid-organ transplant patients require prolonged immunosuppression, increasing their risk of hematologic disorders. For these conditions, allogeneic hematopoietic stem cell transplantation (HSCT) is a potential treatment, but it carries significant risk of treatment-related mortality due to the high possibility of developing rare infectious complications. We report a case of a 55-years-old male with a history of bilateral lung transplantation for extrinsic allergic alveolitis in 2015, who developed acute myeloid leukemia/myelodysplastic syndrome (AML/MDS) with TP53 mutation seven years later.

Evaluation of renal functional reserve with oral protein load or new ultrasound test.

Background: Renal functional reserve (RFR) measures the difference between the stimulated glomerular filtration rate (GFR) and the baseline GFR to detect early signs of renal functional decline. The protein load test (RFR-T) is the gold standard for RFR assessment but is a complicated procedure. Renal intraparenchymal resistance index (RRI) variation test (DRRI-T) is a non-invasive method to measure renal function reserve using ultrasound.

HLA class I expression on human platelets is highly variable and correlates with distinct allele group frequencies.

Background: Human leukocyte antigen (HLA) class I molecules are expressed on platelets and can represent a source of alloimmunization in recipients of platelet transfusions. HLA mismatch between donors and recipients may be associated with the induction of anti-HLA antibodies, which can culminate in refractoriness to platelet transfusions. In the present study we analyzed HLA allele group frequencies and HLA expression levels on human platelets from blood donors.

Rationale for the evaluation of renal functional reserve in allogeneic stem cell transplantation candidates: a pilot study.

Background: The main purpose of our study was to evaluate the ability of renal functional reserve (RFR) to stratify the risk of acute kidney injury (AKI) occurrence within 100 days of hematopoietic stem cell transplantation (HSCT) and to predict any functional recovery or the onset of chronic kidney disease. A secondary aim was to identify the clinical/laboratory risk factors for the occurrence of AKI.

Methods: The study design is prospective observational.

[The genetic basis of post-bone marrow transplant thrombotic microangiopathy: is this the last piece of the puzzle?].

Transplant-associated thrombotic microangiopathy (TA-TMA) is a complication of hematopoietic stem cell transplantation (HSCT) associated with kidney injury and significant mortality. Recent studies indicate that dysregulation of the alternate complement pathway may be at the basis of the development of TA-TMA. Currently, there are no pre-transplant screening tools to identify patients at risk.
