Tacrolimus (FK 506) is a calcineurin inhibitor and is commonly used as an immunosuppressant after a solid organ transplant. One of the serious adverse effects of tacrolimus is thrombotic microangiopathy (TMA) which has a high mortality rate. TMA leads to vascular thrombosis, eventually leading to ischemia of end organs. It is diagnosed clinically and based on the laboratory parameters. Early detection of TMA and prompt treatment can change the course. Drug-induced TMA has a poor prognosis as compared to idiopathic TMA. We present here the case of a 47-year-old male who developed tacrolimus-induced TMA after an orthotopic heart transplant and he was treated with the currently available treatment. He ultimately died after 40 days of hospitalization.

Challenges for complement functional assays in the clinical laboratory: From test validation to clinical interpretation.
J Immunol Methods

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, United States of America. Electronic address:
Complement functional assays are essential first-tier tests for a gamut of disorders spanning from inborn errors of the immune system which lead to recurrent severe infections, to angioedema attacks, presentation of autoimmune disease, thrombotic microangiopathies and rare kidney disorders. These assays evaluate the activity of the three complement pathways and specific complement components, which helps in differential diagnosis and monitoring disease progression. The rising use of complement inhibitors for treating complement-mediated thrombotic microangiopathies has heightened the demand for personalized treatment plans and laboratory assessment of complement blockage.

This study reports the diagnosis and treatment of a 26-year-old pregnant woman with severe malnutrition combined with acute pyelonephritis causing sepsis, refractory septic shock and multiple organ failure. A female patient, 26 years old, was admitted to hospital mainly due to "menelipsis for more than 19 weeks, nausea and vomiting for 20 days, fever with fatigue for 3 days". At the end of 19 weeks of intrauterine pregnancy, the patient presented with fever accompanied by urinary tract irritation.

Introduction of complement (C) inhibition into clinical practice has revolutionized the treatment of patients with complement-mediated atypical hemolytic syndrome (aHUS). Our C3 mouse model, engineered around a gain of function point mutation in C3, is associated with complement mediated aHUS in man, allowing us to study the clinical disease in a preclinical model. Backcrossing our model onto C7 deficient and C5aR1 deficient mice enabled further determination of the roles of the C5a-C5aR1 axis and C5b-9 (the membrane attack complex) on kidney disease.

Congenital thrombotic thrombocytopenic purpura (cTTP) is a thrombotic microangiopathy (TMA) characterized by severe hereditary ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin type 1 motifs 13) deficiency caused by mutations. This rare autosomal recessive genetic disorder is often misdiagnosed as immune thrombocytopenia (ITP) or hemolytic uremic syndrome (HUS). Here, we report a 21-year-old male cTTP patient with a compound heterozygous mutation.

Immune thrombocytopenia (ITP) is an autoimmune hematological condition characterized by a markedly isolated decrease in platelets without any apparent associated clinical conditions, resulting in bleeding and bruising of the skin, mucous membranes, and major organs. It is often triggered by preceding illness or several immune stimulants such as immunizations, infections, allergic reactions, among others. While uncommon, arthropod bites can trigger acute ITP.
