Absence of nephro-protective effect of acetylcysteine in patients with chronic renal failure investigated by coronary angiography

Abstract

Recent studies have suggested that an oral dose of acetylcysteine could play a prophylactic role in the prevention of nephrotoxicity from iodine contrast media in patients affected by chronic renal failure. Between June 2001 and September 2002 we selected 120 patients with a basal plasma creatinine level greater than 1.36 mg/dl investigated by coronary angiography. The treatment group included 60 patients who received 600 mg of acetylcysteine in the morning and evening before the day of the examination together with intravenous saline hydration. The control group patients received hydration alone. The clinical characteristics of the groups were comparable as well as the basal plasma creatinine level: 2.01+/-1.1 mg/dl in the acetylcysteine group and 1.81+/-0.69 in the control group. The plasma creatinine level was measured 24 and 48 hours after coronary angiography. The respective changes in plasma creatinine level at 24 and 48 hours were 0.12+/-0.29 and 0.02+/-0.29 mg/dl in the acetylcysteine group and 0.06+/-0.29 and 0.07+/-0.43 mg/dl in the control group (NS). Acute renal failure caused by the contrast medium, defined by an increase of 25% in the plasma creatinine level compared to the basal value, occurred in 3 patients from...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
