Acute kidney injury on the rise in hospitalized pregnant women

A study presented at ASN Kidney Week 2019 (November 5 to November 10) shows that the rate of acute kidney injury (AKI) is rising among US women who are hospitalized in pregnancy. The highest risk is in pregnant diabetic women. Women who suffer acute damage to the kidney while pregnant have 260 times the risk of death while in hospital compared to other pregnant women, at 2.6% vs 0.01%. Both mother and baby are at risk of increased illness and death if the woman has kidney injury during pregnancy.

Researchers find synergistic connection between two deadly blood-clotting diseases

Two rare but potentially deadly blood-clotting diseases, namely thrombotic thrombocytopenic purpura, or TTP, and hemolytic uremic syndrome, or HUS, show similar pathologies -- a multitude of painful blockages in small blood vessels that cause varying degrees of organ injury throughout the body. However, the two disorders have distinct biological mechanisms.

First therapy indicated for treating adults with rare blood clotting disorder receives FDA approval

The U.S. Food and Drug Administration today approved Cablivi (caplacizumab-yhdp) injection, the first therapy specifically indicated, in combination with plasma exchange and immunosuppressive therapy, for the treatment of adult patients with acquired thrombotic thrombocytopenic purpura (aTTP), a rare and life-threatening disorder that causes blood clotting.

European Commission approves extended indication for Amgen's Kyprolis (carfilzomib) for the treatment of relapsed multiple myeloma patients

Amgen has announced that the European Commission (EC) has approved a variation to the marketing authorization for Kyprolis® (carfilzomib) to include use in combination with dexamethasone alone for adult patients with multiple myeloma who have received at least one prior therapy. The extended indication marks the second approval for Kyprolis by the EC in less than a year.

UAB researcher awarded NIH grant to study pathogenesis of thrombotic microangiopathy

University of Alabama at Birmingham researcher X. Long Zheng, M.D., Ph.D., has received a five-year, $2.5 million National Institutes of Health grant to study the pathogenesis of thrombotic microangiopathy, or TMA. In simple terms, this means looking for factors that cause or aid the onset of extensive microscopic clots in small blood vessels throughout the body. Though tiny, these spots can damage kidneys, heart and brain, and they can cause death.

Omeros reports additional positive data from OMS721 Phase 2 trial for treatment of thrombotic microangiopathies

Omeros Corporation today announced additional positive data in the company's Phase 2 clinical trial of OMS721 for the treatment of thrombotic microangiopathies (TMAs). TMAs are a family of rare, debilitating and life-threatening disorders characterized by excessive thrombi (clots) – aggregations of platelets – in the microcirculation of the body's organs, most commonly the kidney and brain.

Omeros' OMS721 granted FDA Fast Track designation for treatment of atypical hemolytic uremic syndrome

Omeros Corporation today announced that the U.S. Food and Drug Administration granted Fast Track designation to OMS721 for the treatment of patients with atypical hemolytic uremic syndrome (aHUS). OMS721 is the company's lead human monoclonal antibody targeting mannan-binding lectin-associated serine protease-2 (MASP-2), the key regulator of the lectin pathway of the immune system.

Study points to potential treatment for thrombotic thrombocytopenic purpura

A rare autoimmune disease creates sudden pain in the abdomen or the head, sending a patient to the emergency room with a potentially fatal condition. The pain comes from a multitude of blockages of tiny blood vessels, formed after the patient's own immune system somehow inhibits an enzyme that is vital to control clotting.

Platelet transfusion treatment increases death in people with certain rare blood cell disorders

People hospitalized with certain rare blood cell disorders frequently receive a treatment that is associated with a two- to fivefold increase in death, according to a new study that reviewed hospital records nationwide. The study authors recommend that for these rare disorders, doctors should administer the treatment, a platelet transfusion, only in exceptional circumstances.
