Kidney transplantation remains the treatment of choice for end-stage renal failure. When the immune system of the recipient recognizes the transplanted kidney as a foreign object, graft rejection occurs. As part of the host immune defense mechanism, human leukocyte antigen (HLA) is a major challenge for graft rejection in transplantation therapy. The impact of HLA mismatches between the donor and the potential recipient prolongs the time for renal transplantation therapy, tethered to dialysis, latter reduces graft survival, and increases mortality...

KEY POINTS SUMMARY: In this study we investigated whether hypoxia during late pregnancy impairs kidney development in mouse offspring, and also whether this has long-lasting consequences affecting kidney function in adulthood. Hypoxia disrupted growth of the kidney, particularly the collecting duct network, in juvenile male offspring. By mid-late adulthood, these mice developed early signs of kidney disease, notably a compromised response to water deprivation. Female offspring showed no obvious signs of impaired kidney development and did not develop kidney disease, suggesting a underlying protection mechanism from the hypoxia insult...

The intrarenal renin-angiotensin system (iRAS) is implicated in the pathogenesis of hypertension, chronic kidney disease and diabetic nephropathy. Urinary angiotensinogen (uAGT) levels reflect the activity of the iRAS and are altered in women with preeclampsia. Since Indigenous Australians suffer high rates and early onset of renal disease, we hypothesised that Indigenous Australian pregnant women, like non-Indigenous women with pregnancy complications, would have altered uAGT levels. The excretion of RAS proteins was measured in non-Indigenous and Indigenous Australian women with uncomplicated or complicated pregnancies (preeclampsia, diabetes/gestational diabetes, proteinuria/albuminuria, hypertension, small/large for gestational age, preterm birth), and in non-pregnant non-Indigenous women...

BACKGROUND: Renal angiomyolipoma (AML) is a common benign tumor of the kidney. The main complication of AML is retroperitoneal hemorrhage caused by AML rupture, which can be severe and life threatening. The risk of AML rupture used to be determined by tumor size. However, these criteria have been challenged by series of clinical studies and case reports, suggesting prediction AML rupture based on tumor size is not always reliable. METHODS: The authors searched PubMed using "angiomyolipoma," "AML," and "rupture" and reviewed relevant studies...

Pyroglutamic acid, an intermediate in glutathione metabolism, can lead to elevated anion gap metabolic acidosis as rare complication of acetaminophen therapy in adults. Acquired pyroglutamic acidosis has been observed primarily in settings associated with glutathione deficiency. Risk factors for glutathione deficiency include critical illness, chronic liver or kidney disease, advanced age, female gender, alcohol abuse, malnutrition, pregnancy, antiepileptic drugs, and chronic acetaminophen use. Diagnosis of pyroglutamic acidosis requires both the exclusion of common etiologies of increased anion gap metabolic acidosis and a high index of suspicion...

Acute kidney injury (AKI) is a common complication in the neonatal intensive care unit that causes a high mortality of preterm infants and various chronic kidney diseases in adulthood. Preterm infants have immature development of the kidneys at birth. The kidneys continue to develop within a specific time window after birth. However, due to various factors during pregnancy and after birth, preterm infants tend to develop AKI. At present, serum creatinine and urine volume are used for the assessment of kidney injury, and their early sensitivity and specificity have attracted increasing attention...

BACKGROUND: Preeclampsia is a hypertensive syndrome that complicates 3% to 5% of pregnancies in the United States. Preeclampsia originates from an improperly vascularized and ischemic placenta that releases factors that drive systemic pathophysiology. One of these factors, soluble fms-like tyrosine kinase-1, is believed to sequester vascular endothelial growth factor (VEGF), leading to systemic endothelial dysfunction and hypertension. With the goal of targeting soluble fms-like tyrosine kinase-1 while simultaneously preventing fetal exposure to VEGF, we fused VEGF to elastin-like polypeptide, a biopolymer carrier that does not cross the placental barrier (ELP-VEGF)...

BACKGROUND: Preeclampsia is a multisystem vascular disorder of pregnancy that remains a leading cause of maternal and fetal morbidity and mortality. Preeclampsia remains an underrecognized risk factor for future cardiovascular and kidney disease in women and represents the confluence of preexisting vascular risk factors with superimposed endothelial injury from placental mediated anti-angiogenic factors. SUMMARY: This review highlights the close relationship between preeclampsia and future cardiovascular and kidney disease...

Proteinuria is a common adverse effect of renal injury in preeclampsia. To explore the effects of AKR1C3 in renal injury due to preeclampsia and to determine an optimal method to prevent proteinuria, glibenclamide treatment was used in unrestrained Wistar rats exposed to N-nitro-L-arginine methyl ester hydrochloride (L-NAME). Successful rat models for preeclampsia were confirmed based on mean arterial pressure, a 24-h protein urine test, and by observing the structure of the kidney by transmission electron microscopy (TEM)...

The worldwide consumption of energy drinks (EDs) has increased in recent years. EDs have several side effects and can be linked to liver injury, kidney damage and risk-seeking behavior. The impact of perinatal consumption of EDs on the newborns has not been previously investigated. In this study, we evaluated the effects of perinatal exposure to a caffeinated ED on the liver, kidney, brain, locomotor activity and anxiety in mice newborns. Pregnant mice received 2.5 or 5 ml ED by oral gavage from the first day of pregnancy until day 15 after birth...

Thrombotic microangiopathy (TMA) arises in a variety of clinical circumstances with the potential to cause significant dysfunction of the kidneys, brain, gastrointestinal tract and heart. TMA should be considered in all patients with thrombocytopenia and anaemia, with an immediate request to the haematology laboratory to look for red cell fragments on a blood film. Whilst TMA of any aetiology generally demands prompt treatment, this is especially so in thrombotic thrombocytopenic purpura (TTP) and atypical haemolytic uraemic syndrome (aHUS), where organ failure may be precipitous, irreversible and fatal...
