Although gestational hypertension (GH) is thought to be different from preeclampsia (PE), in Japan GH and PE are usually treated as the same disease (i.e., pregnancy-induced hypertension). Here we sought to determine whether there are any differences in fetal growth and maternal kidney function between pregnancies with PE and those with GH. We retrospectively analyzed 61 GH patients and 60 PE patients with singleton pregnancies who delivered at Okayama University Hospital (2008-2015). We compared maternal and perinatal outcomes and maternal kidney function parameters between the GH and PE pregnancies...

Hemolytic uremic syndrome (HUS) is a thrombotic microangiopathy characterized by intravascular hemolysis, thrombocytopenia, and acute kidney failure. HUS is usually categorized as typical, caused by shiga-toxin producing E. coli (STEC) infection, atypical HUS (aHUS), usually caused by uncontrolled complement activation, or secondary HUS with a coexisting disease. In recent years, a general understanding of the pathogenetic mechanisms driving HUS has increased. Typical (i.e. STEC-HUS) follows a gastrointestinal infection with STEC, while aHUS is associated primarily with mutations or autoantibodies leading to dysregulated complement activation...

Uric acid (UA) and folic acid (FA) are compounds of biomedical interest. In humans, about 70% of daily uric acid disposal occurs via the kidneys, and in 5-25% of humans, impaired renal (kidney) excretion leads to hyperuricemia. Folate is another form folic acid of which is known as, is one of the B vitamins. It is used as a supplement by women to prevent neural tube defects developing during pregnancy. Polyortho-methoxyaniline nanostructures (POMANS) was synthesized with a new two phase (organic-water) synthesis method...

INTRODUCTION: Appendicitis is a prevailing cause of acute abdomen, but is often difficult to diagnose due to its wide range of symptoms, anatomical variations, and developmental abnormalities. Urological disorders of the genitourinary tract may be closely related to appendicitis due to the close proximity of the appendix to the genitourinary tract. This review provides a summary of the urological complications and simulations of appendicitis. Both typical and urological symptoms of appendicitis are discussed, as well as recommended diagnostic and treatment methods...

Preeclampsia is characterized by hypertension, proteinuria, suppression of plasma renin-angiotensin-aldosterone, and impaired urine sodium excretion. Aberrantly filtered plasmin in urine may activate proteolytically the γ-subunit of the epithelial sodium channel (ENaC) and promote Na(+) reabsorption and urine K(+) loss. Plasma and urine was sampled from patients with preeclampsia, healthy pregnant controls and non-pregnant women, and from patients with nephrostomy catheters. Aldosterone concentration, urine plasminogen, and protein were determined...

Generalized arterial calcification of infancy (GACI) is an autosomal recessive disorder caused by mutations in the ENPP1 gene. It is characterized by mineralization of the arterial blood vessels, often diagnosed prenatally, and associated with death in early childhood. There is no effective treatment for this devastating disorder. We previously characterized the Enpp1asjmutant mouse as a model of GACI, and we have now explored the effect of elevated dietary magnesium (five-fold) in pregnant mothers and continuing for the first 14 weeks of postnatal life...

BACKGROUND AND OBJECTIVES: Kidney disease is a critical concern in counseling patients with lupus considering pregnancy. This study sought to assess the risk of renal flares during pregnancy in women with previous lupus nephritis in partial or complete remission, particularly in those with antidouble-stranded DNA antibodies and low complement levels, and the risk of new-onset nephritis in patients with stable/mildly active SLE. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We assessed active nephritis (renal flares and de novo kidney disease) and associated predictors during pregnancy in patients with lupus with urine protein ≤1000 mg and serum creatinine <1...

Liddle syndrome is an autosomal dominant genetic condition that causes hypertension and hypokalemia due to a gain-of-function mutation in the SCNN1B or SCNN1G genes which code for the epithelial sodium channel in the kidney. This leads to increased sodium and water reabsorption causing hypertension. We report a case of a 27-year-old pregnant woman who was admitted for hypertension and hypokalemia and later diagnosed and treated for Liddle syndrome using amiloride. Maintaining a high suspicion of Liddle syndrome in pregnancy is essential in such cases to be able to adequately and effectively treat the hypertension...

In ovine pregnancy, uterine space restriction (USR) resulting from decreased space for placental attachment caused intrauterine growth restriction and impaired nephrogenesis. The fetal kidney renin-angiotensin system (RAS) is involved in nephrogenesis, fluid balance, and iron deposition. Angiotensin II exerts its effects via multiple receptors: angiotensin II 1-8 receptor type 1 (AT 1 R) and type 2 (AT 2 R), and angiotensin II 1-7 Mas receptor (MASR). Objective: : To test the hypothesis that ovine USR is associated with dysregulation of the fetal renal RAS...

Glomerular disease, especially lupus nephritis, is common in young women of childbearing age. As such, practicing nephrologists must have adequate knowledge and expertise to prepare these women for pregnancy, to diagnose and manage the numerous pregnancy-associated complications that are common in this vulnerable patient population and finally to support these young women who often struggle to manage both their young children along with an often onerous chronic disease. In this article we will review the pre-pregnancy counseling these women should ideally receive to allow them to make an informed decision about proceeding with a pregnancy, an approach to the diagnosis of pregnancy-associated worsening of kidney function and proteinuria as well as pregnancy-safe management strategies, including immunosuppression, antihypertensive agents and other medications necessary for the management of nephrotic syndrome...

BACKGROUND: All countries face significant challenges from complex manifestations of malnutrition, which affects one in three people globally. Systematic reviews provide ready-to-use syntheses of quality-appraised evidence to inform decision-making for actions. To enhance the utility and quality of future Cochrane nutrition evidence, we described the scope and quality of all nutrition systematic reviews in the Cochrane Database of Systematic Reviews (CDSR). METHODS: We screened all active CDSR records (31 July 2015) to identify reviews and protocols using pre-specified eligibility criteria and definitions...

INTRODUCTION: Kidney damage during pregnancy constitutes a diagnostic and therapeutic challenge. However, it is not entirely known whether a kidney condition recognised before the pregnancy releases an organism's response to pregnancy, or whether pregnancy itself worsens kidney function. OBJECTIVE: The aim of the study was immunohistochemical evaluation of cells of kidneys of pregnant rats under the influence of nitric oxide (NO), with measurement of the immunoexpression of cellular stress markers (p-53, HSP 70)...

BACKGROUND: We determined if maternal nutrient restriction (MNR) in guinea pigs leading to fetal growth restriction (FGR), impacts markers for tissue hypoxia implicating a mechanistic role for chronic hypoxia. METHODS: Guinea pigs were fed ad libitum (Control) or 70% of the control diet pre-pregnant switching to 90% at mid-pregnancy (MNR). Near term, Hypoxyprobe-1 (HP-1), a marker of tissue hypoxia, was injected into pregnant sows. Fetuses were then necropsied and liver, kidney and placental tissues were processed for erythropoietin (EPO), EPO-receptor (EPOR), and VEGF protein levels, and for HP-1 immunoreactivity (IR)...

Oral-facial-digital syndrome type 1 (OFD1; OMIM# 311200) is an X-linked dominant ciliopathy caused by mutations in the OFD1 gene. This condition is characterized by facial anomalies and abnormalities of oral tissues, digits, brain, and kidneys. Almost all affected patients are female, as OFD1 is presumed to be lethal in males, mostly in the first or second trimester of pregnancy. Live born males with OFD1 are a rare occurrence, with only five reported patients to date. In four patients the presence of a congenital heart defect (CHD) was observed...

We studied possible involvement of prolactin in the regulation of bicarbonate biodynamics using female rat model of cholestasis of pregnancy induced by transplantation of the donor pituitary under the renal capsule of a recipient (hyperprolactinemia) and bile duct ligation (cholestasis). The concentration of bicarbonates in the bile and blood, their excretion, clearance, and reabsorption, as well as glomerular filtration rate and excretion of sodium ions were assessed. It was found that the main effect of prolactin was directed to the kidney-regulated pool of bicarbonates and consisted in stimulation of their clearance and inhibition of reabsorption, which led to a decrease in bicarbonate blood concentration...
