Ten-year experience with nephrogenic systemic fibrosis: case-control analysis of risk factors

Abstract

To analyze all cases of nephrogenic systemic fibrosis (NSF) at our institution and to compare them with controls. After the institutional review board approval, 13 biopsy-proven NSF cases were identified. Ten cases had complete records and were compared in a case-control format with 10 age- and sex-matched, dialysis-dependent controls. Analyzed risk factors included single and cumulative gadolinium dose, medication and transplant history, and serum electrolytes at the time of gadolinium exposure. There were 1.9% of dialysis-dependent, gadolinium-exposed patients who developed NSF. There was no difference in gadolinium dose, transplant history, or serum electrolytes. Seven of 10 cases and 3 of 10 controls were treated with erythropoietin (P = 0.13). At the time of NSF diagnosis, 7 of 10 cases were on immunosuppressive therapy. Two of 7 cases developed NSF only after immunosuppressive therapy was initiated. Two of 10 controls were on immunosuppressive therapy (P = 0.06). All cases of NSF occurred in dialysis-dependent, gadolinium-exposed patients. Associations between immunosuppressive and erythropoietin therapies and NSF need further investigation.

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.
