All-trans retinoic acid-induced multiple mononeuropathies

All Trans Retinoic Acid (ATRA) induced myositis.

A 5-year-old girl presented with fever, skin and mucosal bleeds, and pallor. Her hemoglobin was 3.6 g/dL, total white cell count 4.5×103/μL and platelet count 13×103/μL. Peripheral smear revealed 30% blasts, confirmed as APML on bone marrow examination. Cytogenetic analysis showed the typical translocation of t(15:17) with 77% of interphase cells expressing PML:RARA gene fusion. Child was start...

All-trans-retinoic acid: measurement

A quantitative determination of physiological levels of all-trans-retinoic acid (vitamin A acid) in human serum has been developed. A double-phase extraction of 3.5 ml of serum followed by a specific and sensitive high performance liquid chromatography procedure allowed measurement of levels down to 1 ng/ml. Serum concentrations in 37 fasting volunteers ranged from 2.7 to 4.2 ng/ml and fitted a...

All-trans-retinoic acid-induced rhabdomyolysis: a case report

All-trans retinoic acid (ATRA) induced rhabdomyolysis in the induction treatment of acute promyelocytic leukemia (APL) is a very rare complication. However, rhabdomyolysis-related acute renal failure increases the risk of high morbidity and mortality. Here we describe a case of rhabdomyolysis associated with ATRA during the induction therapy in an adult with APL. Clinical implications are discu...

All-trans-retinoic acid and bleeding/thrombosis.

These effects have become a therapeutic objective in human cancers. In addition to these functions, ...
