Hypertension can originate from early-life insults, whereas maternal melatonin therapy can be protective in a variety of models of programmed hypertension. We hypothesize that melatonin or melatonin receptor agonist agomelatine can prevent programmed hypertension in adult offspring induced by maternal exposure to continuous light. Female Sprague-Dawley pregnant rats randomly divided into four groups: controls, rats exposed to continuous light, exposed to continuous light plus treated with agomelatine (50mg/day i...

The incidence of acute kidney injury in pregnancy (P-AKI) in developed countries is significantly lower than in developing ones, where it is estimated to range between 4 and 26%. Mortality in cases of P-AKI requiring dialysis is high, varying from 20 to 80%. In developing countries, clinical decisions are often based on the availability of services and not on needs. Prenatal surveillance in Mexico does not include serum creatinine, limiting the potential for early diagnosis of AKI and CKD and their differential diagnosis...

Fabry disease is a rare X-linked lysosomal storage disorder of glycosphingolipid catabolism caused by deficient activity of the lysosomal hydrolase alpha-galactosidase A (ɑ-Gal A). A 20-year-old woman was referred to our hospital because of proteinuria and persistent macroscopic hematuria. Based on the typical renal pathological findings, deficient activity of the ɑ-Gal A, and heterozygous mutation in the ɑ-Gal A gene, she was diagnosed with Fabry disease. After 1 year of enzyme replacement therapy with agalsidase alfa at 0...

Curing 'diabetic nephropathy' is considered an unmet medical need of high priority. We propose to question the concept of 'diabetic nephropathy' that implies diabetes as the predominant cause of kidney disease, which may not apply to the majority of type 2 diabetics approaching end-stage kidney disease. With the onset of diabetes, hyperglycaemia/sodium-glucose co-transporter-2-driven glomerular hyperfiltration promotes nephron hypertrophy, which, however, on its own, causes proteinuria not before a decade later, probably because podocyte hypertrophy can usually accommodate an increase in the filtration surface...

OBJECTIVE: The number of successful pregnancies in kidney transplant (KT) recipients has increased in recent years. Little evidence is available about the risk of in utero immunosuppressive exposure for long-term cognitive consequences. The aim of this study was to evaluate the impact of immunosuppression during pregnancy on intellectual performance of children born to KT recipients. METHODS: Using a cross-sectional design, women who had undergone KT and their children (aged 4+ years) were recruited at the outpatient follow-up in five transplant centers...

BACKGROUND AND OBJECTIVE: Hypertension is one of the common medical complications of pregnancy and contributes significantly to maternal and perinatal morbidity and mortality. Uric acid (UA) is filtered, reabsorbed and secreted by the kidney. Thus, this study was conducted to assess the serum UA levels in PIH and to evaluate the diagnostic value of serum UA level in PIH. MATERIALS AND METHODS: This is a hospital based comparative cross-sectional study conducted in BPKIHS...

BACKGROUND: A large number of studies have shown hypertension of offspring in adulthood is related to parental health during pregnancy. Hydrogen sulfide (H2S) could relax placental vasculature and improve intrauterine growth restriction. In the present study, we want to observe the effect of H2S on the fetal programming of renovascular hypertension, a rat model of secondary hypertension. METHODS: Renovascular hypertension was induced by 2-kidney-1-clip, their adult pups were used to evaluate basal blood pressure...

PURPOSE OF REVIEW: The current article reviews the available literature on the incidence, complications, outcomes, and management of pregnancies in kidney transplant recipients. RECENT FINDINGS: Pregnancy can be a reasonable option for women with a kidney transplant. More than 4700 successful pregnancies have been reported after kidney transplantation. New data have emerged regarding the risk of allograft dysfunction following pregnancy. There is a lack of consensus on the optimal time for conception, immunosuppressive targets, the safety of allograft biopsy, and infection surveillance...

Next-generation sequencing has dramatically decreased the cost of gene sequencing, facilitating the simultaneous analysis of multiple genes at the same time; obtaining a genetic result for an individual patient has become much easier. The article by Ars and Torra in this issue of the Clinical Kidney Journal provides examples of the ever-increasing ability to understand a given patient's disease on the molecular level, so that in some cases not only the causative variants in a disease gene are identified, but also potential modifiers in other genes...

Several ethical aspects in the management of Autosomal Dominant Polycystic Kidney Disease (ADPKD) are still controversial, including family planning and testing for disease presence in at-risk individuals. We performed an online survey aiming to assess the opinion and current clinical practice of European pediatric and adult nephrologists, as well as geneticists. A total of 410 clinicians (53% male, mean (SD) age of 48 (10) years) responded, including 216 pediatric nephrologists, 151 adult nephrologists, and 43 clinical geneticists...

REVIEW
Fadi Fakhouri, Clément Deltombe
The rate of pregnancy-associated acute kidney injury (P-AKI) has dwindled in high income countries mainly following the legalization of abortion in the seventies and early eighties and the general improvement in obstetrical care. P-AKI has not however disappeared from high income countries and several reports indicate that its frequency has even increased during the last decade. The reasons for such evolution are probably an improved surveillance and reporting of P-AKI and a more aggressive approach to the treatment of pregnancy complications, with unintended renal side effects...

Sulfate is an obligate nutrient for fetal growth and development. In mice, the renal Slc13a1 sulfate transporter maintains high maternal circulating levels of sulfate in pregnancy, and the placental Slc13a4 sulfate transporter mediates sulfate supply to the fetus. Both of these genes have been linked to severe embryonal defects and fetal loss in mice. However, the clinical significance of SLC13A1 and SLC13A4 in human gestation is unknown. One approach towards understanding the potential involvement of these genes in human fetal pathologies is to use an animal model, such as the pig, which mimics the developmental trajectory of the human fetus more closely than the previously studied mouse models...

Icariin has previously been demonstrated to attenuate hyperglycemia‑induced renal injury, however the renoprotective effects of icariin in a rat model of pregnancy‑induced hypertension (PIH) remain to be elucidated. The present study aimed to investigate the effect of icariin on PIH‑induced acute kidney injury (AKI) and proteinuria. Following 18 days of icariin treatment between day 1 and day 18 of gestation, which was combined with NG‑nitro‑L‑arginine methyl ester (L‑NAME) treatment between day 12 and day 18 of gestation to induce PIH, the 24 h urine protein level, blood urea nitrogen and serum creatinine were measured by using the Coomassie Brilliant Blue method, a commercial enzymatic kit and the picric acid method, respectively...

We present a case of a foetal sonographic finding of hyper-echogenic kidneys, which led to a strategic series of genetic tests and identified a homozygous mutation (c.424C > T, p. R142*) in the NPHP3 gene. Our study provides a rare presentation of NPHP3-related ciliopathy and adds to the mutation spectrum of the gene, being the first one from Pakistani population. With a thorough literature review, it also advocates for molecular assessment of ciliopathies to improve risk estimate for future pregnancies, and identify predisposed asymptomatic carriers...

Pregnancy is probably the most important challenge in young women with chronic kidney disease (CKD). The challenge is greater in developing countries, in which access to dialysis is uneven, and prenatal care for CKD patients is not uniformly available. This case report summarizes some of the challenges faced by pregnant CKD women in a developing country. A 35-year-old woman, affected by an undiagnosed kidney disease, experienced preeclampsia at 24 years of age, and started dialysis in emergency at age 31 in the context of severe preeclampsia in her second pregnancy...
