Clinical Report Acute kidney injury in a preterm infant homozygous for the C3435T polymorphism in the ABCB1 gene given oral morphine

چکیده
A 34-week infant born from a mother with a history of drug abuse developed neonatal abstinence syndrome (NAS) in the first hours of life. Urine drug screening was positive for cocaine and heroin. The infant developed acute kidney injury and bilateral hydronephrosis while receiving oral morphine for control of NAS. Cessation of morphine therapy and urinary catheterization resulted in a rapid and complete resolution of the symptoms. Our patient was homozygous for the C3435T polymorphism in the ABCB1 gene, a polymorphism previously associated with impaired P-glycoprotein activity. We hypothesize that acute renal toxicity was related to accumulation of morphine within urothelial cells due to genetically determined impaired P-glycoprotein activity.

متن کاملAssociation of Acute Lymphoblastic Leukemia and MDR1 Gene Polymorphism in an Ethnic Iranian Population
Background: The frequency of the multi-drug resistance 1 (MDR1) gene C3435T polymorphism differs in various ethnical populations such as Asian, African, and Caucasians populations. A silent C3435T polymorphism in exon 26 of MDR1 has been reported to be associated with a decreased expression of P-gp in TT genotypes carriers compared with CC genotypes carriers. Materials and Methods: To evaluate ...
متن کاملEffect of single nucleotide polymorphisms in the ATP-binding cassette B1 gene on the clinical outcome of traumatic brain injury.
The critical role of ATP-binding cassette B1 (ABCB1) in the function of the blood-brain barrier led us to conducted this prospective study in order to investigate the clinical outcome of patients suffering from severe traumatic brain injury. A total of 182 patients with traumatic brain injury were included in our study. Genotyping of ABCB1 C3435T and G2677T/A was conducted using polymerase chai...

We conducted a case-control study to investigate the role of ABCB1 C3435T (rs1045642) and C1236T (rs1128503) gene polymorphisms in the susceptibility to acute myeloid leukemia. The polymerase chain reaction (PCR) coupled with restriction fragment length polymorphism (RFLP) method was carried out to genotyping ABCB1 C3435T and C1236T gene polymorphism. Statistical analysis was conducted using th...
