Blunt renal trauma-induced hypertension: prevalence, presentation, and outcome

American Journal of Hypertension
Antoine ChedidPierre-François Plouin

Abstract

Blunt renal trauma (RT) may cause hypertension. We assessed the frequency and mechanisms of RT, and blood pressure (BP) outcome after treatment. We searched the records of all patients referred to our hypertension unit and included those of previously normotensive patients who developed hypertension within 6 months of RT. Ten of the 17,410 referred patients, with a median age of 26 years, developed hypertension 0 to 3 months after a well-documented RT. Median BP at referral was 170/107 mm Hg. Median glomerular filtration rate was 89 mL/min. Five patients had hematuria. Median kidney length was 107 mm on the damaged side and 114 mm on the opposite side. Renal artery lesions were present in six cases. A pattern of unilateral renin hypersecretion and contralateral suppression was present in five of eight cases with unilateral RT. Six patients underwent surgery. Seven months after referral, median BP was 128/79 mm Hg. The BP was <140/90 mm Hg without medication in one patient who did not undergo surgery and in three patients who did. Renal trauma is a rare cause of hypertension, mostly in young men. Hypertension is usually renin dependent and associated with parenchymal injury. The RT-induced hypertension may resolve spontaneously ...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.
