Comprehensive Analysis of Thrombotic Microangiopathy Following Renal Transplantation.

Thrombotic microangiopathy is a severe complication of renal transplantation. Little is known about risk factors, incidence of autoantibodies against complement components, and prognosis. Clinical and laboratory data were retrospectively collected for 13 patients diagnosed with post-transplant thrombotic microangiopathy (PT-TMA) in 2011-2018.

Coronary Artery Disease and Microvascular Ischemia in Patients with Cardiac Amyloidosis.

Introduction: The prevalence of preexisting obstructive coronary artery disease (CAD) and the occurrence of anginal chest pain as a presenting symptom in patients with light-chain (AL) and transthyretin (ATTR) cardiac amyloidosis (CA) are undetermined.

Methods: A single-center analysis of clinical, laboratory, imaging, and angiographic characteristics of CA cohort was performed.

Results: Included were 98 CA patients (43 AL, 47 wtATTR, 8 mutant ATTR).

The Number of Episodes of Subtherapeutic Tacrolimus Blood Level Is Independently Associated With Reduced Kidney Graft Survival.

Background: Tacrolimus blood level variability is associated with reduced graft survival among kidney transplant recipients. To date, no practical approach for reducing variability has been validated. We defined specific tacrolimus blood level patterns correlated with variability and evaluated their independent association with reduced graft survival.

MDS patient registries - achievements and challenges.

Since the late 1980s, patient registries have played a pivotal role in the elucidation of rare diseases. For myelodysplastic syndromes (MDS), they revealed the disease actually to be diverse rather than rare. Registry data enabled the definition of various MDS subtypes and prognostic scores tailoring therapy.
