To analyze the relationship between hyperuricemia and primary nephrotic syndrome in childhood. A retrospective study was carried out in 107 children with primary nephrotic syndrome. The clinical data were analyzed with statistical methods to identify the related factors with hyperuricemia. The morbidity of hyperuricemia in children with primary nephrotic syndrome was 45% (48/107). Compared to those in normal serum uric acid group, the incidence of hypertension (33%, 16/48), serum triglyceride [2.59(1.62-3.87) mmol/L], creatinine [43.85(33.38-56.38)mmol/L], urea [6.11(3.77-8.40)mmol/L] and blood uric acid/creatinine ratio [9.30(7.03-12.72)] increased while creatinine clearance rate [141.74(103.57-160.97)ml/(min·1.73 (2))] decreased in hyperuricemia group. Hyperuricemia in children with primary nephrotic syndrome correlated with the increase of serum creatinine, urea and blood uric acid/creatinine ratio, the decrease of creatinine clearance rate and the occurance of hypertension.

To assess the efficacy of levamisole in frequently relapsing nephrotic syndrome and steroid-dependent nephrotic syndrome. Retrospective analysis of hospital case records. Pediatric nephrology department of a tertiary referral pediatric hospital. 62 children with frequently relapsing nephrotic syndrome and 35 children with steroid-dependent nephrotic syndrome. Case records of children who were diagnosed as steroid-dependant or frequently-relapsing nephrotic syndrome from June 2004 to June 2011, were reviewed. Levamisole was given daily (2 mg/kg/d) along with tapering doses of alternate day steroids after remission on daily steroids. Levamisole was effective in 77.3% children with a better (80.6%) efficacy in frequently relapsing nephrotic syndrome. A total of 34 children completed 1 year follow-up post levamisole therapy. The cumulative mean (SD) steroid dose 1-year before therapy was 4109(1154) mg/m2 and 1-year post therapy was 661 (11) mg/m2 (P<0.001). The relapses were also less during the period of post-levamisole therapy. Levamisole is an effective alternative therapy in frequently relapsing and steroid-dependent nephrotic syndrome.

Congenital nephrotic syndrome is a rare disorder. Heavy proteinuria, hypoalbuminemia, and edema occur during the first 3 months of life. Initial cases were reported from Finland and sporadic cases have occurred elsewhere. Finnish cases demonstrated an autosomal recessive inheritance pattern; currently, Finnish and non-Finnish types are recognized. The clinical course consists of failure to thrive, frequent infections, declining renal function, and early death by age 4 years from sepsis or uremia. Recently renal transplantation has improved the prognosis of patients with this disease. An abnormal Ga-67 scan in a case of congenital nephrotic syndrome is presented

2015-01-01

Although syncope and nephrotic syndrome are frequently encountered independently in pediatric practice, syncope as the initial symptom for nephrotic syndrome is rarely observed in the pediatric age group. In this report, we present the case of 3-year-old boy with nephrotic syndrome who presented with a history of three episodes of syncope before admission. The syncope occurred after excessive fluid loss or inadequate intake of fluids and was relieved spontaneously. History taking revealed that the early morning palpebral edema, and laboratory tests showed decreased plasma protein levels and elevated serum lipid levels. Nephrotic syndrome was diagnosed, but could not be confirmed histopathologically because the patient’s parent refused consent for biopsy. The patient was managed with fluid expansion, correction of acidosis, and improvement of microcirculation to prevent recurrence of syncope, and glucocorticoids were administered to prevent disease progression.

Full Text Available Adult-onset nephrotic syndrome differs from its pediatric counterpart in several important ways. Most importantly, nephrotic syndrome in adults is more etiologically heterogeneous compared to children, and thus treatment approaches rely heavily on the histologic diagnosis provided by renal biopsy. The evidence-based approach to treatment of adult nephrotic syndrome has been critically examined by the Kidney Disease Improving Global Outcomes (KDIGO guidelines in glomerulonephritis, published in 2012. Here, we examine the strengths and limits of those guidelines and review recent work that expands the evidence-based approach.

Nephrotic syndrome is a common chronic illness encountered during childhood. Infections have been identified as a cause of nephrotic syndrome. The aim of this study was to evaluate the association between enteroviral infection and nephrotic syndrome. A nationwide retrospective cohort study was conducted by analyzing data from the National Health Insurance Research Database in Taiwan. Children aged children were randomly selected as the comparison cohort. The primary endpoint was the occurrence of nephrotic syndrome. This study included 280,087 enterovirus-infected children and 280,085 non-enterovirus-infected children. The mean age of the enterovirus-infected children was 2.38 years, and 53.7% of these children were boys. The overall incidence densities of nephrotic syndrome for enterovirus- and non-enterovirus-infected children were 2.65 and 2.21 per 10,000 person-years, respectively. The enterovirus-infected cohort had a higher cumulative incidence of nephrotic syndrome than did the non-enterovirus-infected cohort (log-rank test, p = 0.01). Multivariable analyses revealed that children with enteroviral infection were significantly associated with an increased risk of nephrotic syndrome compared with those without enteroviral infection (adjusted hazard ratio, 1.20; 95% confidence interval, 1.04-1.39; p = 0.01), particularly in children infected with coxsackievirus. Subgroup analyses revealed that enterovirus-infected girls, children of blue-collar workers, and children without allergies had a higher risk of nephrotic syndrome than did children in the non-enterovirus-infected cohort. This study revealed a significant association between enteroviral infection and nephrotic syndrome. Additional studies elucidating the role and pathogenesis of enterovirus in nephrotic syndrome are warranted.

We report the case of a 38-year-old male with autosomal-dominant polycystic kidney disease (ADPKD) and concomitant nephrotic syndrome secondary to membranous nephropathy (MN). A 3-month course of prednisone 60 mg daily and losartan 100 mg daily resulted in resistance. Treatment with chlorambucil 0.2 mg/kg daily, low-dose prednisone, plus an angiotensin-converting enzyme inhibitor (ACEI) and an angiotensin II receptor blocker (ARB) for 6 weeks resulted in partial remission of his nephrotic syndrome for a duration of 10 months. After relapse of the nephrotic syndrome, a 13-month course of mycophenolate mofetil (MFM) 2 g daily and low-dose prednisone produced complete remission for 44 months. After a new relapse, a second 24-month course of MFM and low-dose prednisone produced partial to complete remission of proteinuria with preservation of renal function. Thirty-six months after MFM withdrawal, complete remission of nephrotic-range proteinuria was maintained and renal function was preserved. This case supports the idea that renal biopsy is needed for ADPKD patients with nephrotic-range proteinuria in order to exclude coexisting glomerular disease and for appropriate treatment/prevention of renal function deterioration. To the best of our knowledge, this is the first reported case of nephrotic syndrome due to MN in a patient with ADPKD treated with MFM, with remission of proteinuria and preservation of renal function after more than 10 years. Findings in this patient also suggest that MFM might reduce cystic cell proliferation and fibrosis, preventing progressive renal scarring with preservation of renal function. PMID:21552769

Full Text Available Background and Aim: Steroid-resistant nephrotic syndrome (SRNS accounts for 10%-20% of all cases of idiopathic nephrotic syndrome. These patients are at risk of developing end-stage renal disease. The aim of this study was to determine the demographic characteristics, renal biopsy findings, response to immunosuppressive treatment, and prognosis in pediatric patients with SRNS.Materials and Methods: This retrospective study included 31 patients diagnosed as primary SRNS. Age at first episode, gender, parental consanguinity, and familial history of nephrotic syndrome were recorded. Demographic characteristics, renal biopsy findings, response to immunosuppressive treatment, and prognosis were analyzed, as were the number of and treatment of relapses, extra-renal manifestations, and complications of disease and treatment.Results: Mean age at first episode of nephrotic syndrome was 4,1±2,9 years. At the end of the first immunosuppressive treatment cycle, 14 (51.8% patients achieved complete remission, 4 (14.8% patients achieved partial remission, and 9 patients (33.3% did not achieve remission. Analysis of the final status of the patients showed that 16 patients (51.6% developed remission, 5 patients (16% continued to have nephrotic range proteinuria and 10 patients (32% developed chronic renal failure (CRF.Conclusion: The treatment of SRNS remains controversial. Early genetic testing can help the inevitable immunosuppressive treatments which may not be effective and have several side effects. Calcineurin inhibitors and mycophenolate mofetil are known to be effective immunosuppressive drugs for treating steroid resistant nephrotic syndrome .

Nephrotic syndrome is a chronic disease that may act as a risk for other major infection in skin, respiratory and urinary tract, while also increasingthe chance for other diseases, like peritonitis, meningitis, and cellulitis. Cellulitis is often caused by Streptococcus β-hemolytic, Staphylococcus aureus, and Escherichia coli. The clinical features of cellulitis marked with redness rash and well-defined borders, pain pressure and swelling. Hypoalbuminemia which occurs due to proteinuria occurred in this patient acts as a risk factor for cellulitis. It has been reported the case of cellulitis as one of the complications of the nephrotic syndrome in the pediatric patient. The treatment has been given to the patient such as antibiotics and supportive therapy and also planned albumin substitution.

The treatment of steroid-resistant focal segmental glomerulosclerosis (FSGS) imposes one the most perplexing and frustrating problems on nephrologists. Cyclosporine A (CsA) is widely considered as the treatment of choice for steroid-resistant or dependent nephrotic children. We reviewed the clinical outcome in children with idiopathic nephrotic syndrome (INS) under CsA treatment. A total of 22 children presented with either steroid resistant nephrotic syndrome (SRNS) (14 children), or steroid-dependent nephrotic syndrome (SDNS) (8 children) during the period from August 2002 to February 2005; the mean age for both groups was 7.6 years (range: 23 months-15 years). Renal histology showed FSGS in 14 (63%) patients, minimal change disease (MCD) in 4(18%), diffuse mesangial glomerulonphritis (MesGN) in three (13.6%), and membranous glomerulonephritis (MGN) in two (6.8%). Treatment with CsA in combination with alternate-day prednisolone induced remission in 15(68%) patients; 9(60%) patients had complete remission and six (40%) partial remission. Seven (50%) patients in SRNS group responded to CsA treatment; two (14.2%) patients had complete remission and 5 (35.7%) had partial remission. Seven ( 87.5%) children in SDNS group had complete remission and one (13.5%) had partial remission. We conclude that this study demonstrates the efficacy of CsA in inducing remission in the steroid dependent is higher than in the steroid resistant nephrotic children. We believe that CsA is probably a good alternative therapy in this population. (author)

Full Text Available OBJECTIVES: Familial steroid-sensitive idiopathic nephrotic syndrome is rare, and only approximately 3% of patients have affected siblings. METHODS: Herein, we report seven cases of patients with steroid-sensitive idiopathic nephrotic syndrome from three Chinese families. Mutational screening of the Nphs2 gene was performed in all the patients. RESULTS: All seven of the familial steroid-sensitive idiopathic nephrotic syndrome cases in our sample exhibited minimal change disease, and one case also presented with mesangial proliferative glomerulonephritis, according to the renal pathology. No significant was associations were found between Nphs2 gene mutations and the onset of proteinuria and nephrotic syndrome in these familial cases. CONCLUSIONS: The presence of minimal change disease is important, but it is not an unusual finding in patients with familial steroid-sensitive idiopathic nephrotic syndrome, which appears to be clinically benign and genetically distinct from other types of nephrosis.

Full Text Available The etiology of nephrotic syndrome is complex and ranges from primary glomerulonephritis to secondary forms. Patients with nephrotic syndrome often need immunosuppressive treatment with its side effects and may progress to end stage renal disease. This review focuses on recent advances in the treatment of primary causes of nephrotic syndrome (idiopathic membranous nephropathy (iMN, minimal change disease (MCD, and focal segmental glomerulosclerosis (FSGS since the publication of the KDIGO guidelines in 2012. Current treatment recommendations are mostly based on randomized controlled trials (RCTs in children, small RCTs, or case series in adults. Recently, only a few new RCTs have been published, such as the Gemritux trial evaluating rituximab treatment versus supportive antiproteinuric and antihypertensive therapy in iMN. Many RCTs are ongoing for iMN, MCD, and FSGS that will provide further information on the effectiveness of different treatment options for the causative disease. In addition to reviewing recent clinical studies, we provide insight into potential new targets for the treatment of nephrotic syndrome from recent basic science publications.

The purpose of this study was to report a case of a woman with nephrotic syndrome who presented with blurred vision because of bilateral serous macular detachment. Case report and literature review. A 55-year-old woman with a history of essential hypertension, diabetes, and nephrotic syndrome was presented with blurred vision in both eyes. Her fluorescein angiography revealed dye leakage in the early and subretinal pooling in the late phases, and optical coherence tomography scans confirmed the presence of subretinal fluid in the subfovel area. In nephrotic syndrome cases especially with accompaniment of high blood pressure, fluid accumulation in the retina layer may occur. Serous macular detachment must be kept in mind when treating these patients.

Hyperhomocyst(e)inemia is an independent risk factor for atherothrombosis in several clinical settings in which renal function is impaired, but its prevalence in the nephrotic syndrome has not been investigated in detail, even though this syndrome provides an excellent model in which to study a possible link between albuminuria, proteinuria, and hyperhomocyst(e)inemia. We obtained plasma and urine from 27 patients with biopsy-confirmed membranous glomerulonephritis presenting nephrotic syndrome and 27 matched controls and determined the concentrations of homocyst(e)ine and proteins considered putative markers of glomerular and tubular function. Hyperhomocyst(e)inemia, defined as the mean +SD of the plasma homocyst(e)ine concentration of the controls [plasma homocyst(e)ine concentration >10.8 micromol/l] was present in 26% of the patients with nephrotic syndrome but in only 7.4% of the controls. Furthermore, the degree of hyperhomocyst(e)inemia was more severe in the nephrotic patients than in the controls. The existence of renal failure, tubular damage, and, interestingly, relatively well conserved glomerular function barrier were the main predictors of increased levels of plasma homocyst(e)ine. In conclusion, hyperhomocyst(e)inemia is a frequent cardiovascular risk factor present in patients with nephrotic syndrome and renal failure, but it is not directly associated with proteinuria.

Prolonged steroid therapy is generally used for steroid-dependent nephrotic syndrome in pediatric patients. However, dwarfism secondary to a long-term regimen and its successful reverse is rarely reported. The underlying mechanism of dwarfism is still poorly understood, as both long-term steroid use and nephrotic syndrome may interact or independently interfere with the process of growth. Here, we present a 17-year-old patient with dwarfism and steroid-dependent nephrotic syndrome and the successful treatment by recombinant human growth factor and cyclosporine A with withdrawal of steroid. We also briefly review the current understanding and the management of dwarfism in pediatric patients with nephrotic syndrome.

Full Text Available Background Children with nephrotic syndrome need high-dose corticosteroids to achieve remission. Studies have estimated a 35-43% risk of obesity in these patients after corticosteroid treatment. Objective To determine the prevalence of obesity in children who received corticosteroids for nephrotic syndrome, and to compare the risk of obesity in children with steroid-sensitive nephrotic syndrome (SSNS and steroid-resistant nephrotic syndrome (SRNS. Methods We performed a retrospective cohort study in 50 children with SSNS or SRNS who received corticosteroid treatment. Obesity was defined to be a BMI-for-age Z-score above +2.0 SD, according to the WHO Growth Reference 2007. Central obesity was defined to be a waist-to-height ratio > 0.50. Results The overall prevalence of obesity was 22%, with 29% and 14% in the SSNS and SRNS groups, respectively. The overall prevalence of central obesity was 50%, with 54% and 46% in the SSNS and SRNS groups, respectively. The cumulative steroid doses in this study were not significantly different between the SSNS and SRNS groups. There were also no significant differences between groups for risk of obesity (RR 2.53; 95%CI 0.58 to 10.99 or central obesity (RR 1.39; 95%CI 0.45 to 4.25. Conclusion In children with nephrotic syndrome who received corticosteroids, the prevalence of obesity is 22% and of central obesity is 50%. In a comparison of SSNS and SRNS groups, cumulative steroid dose as well as risks of obesity and central obesity do not significantly differ between groups.

The aim of the study is to assay the clinical application of kidney sonography and dynamic scintigraphy with 99m Tc-DTPA in children presenting nephrotic syndrome. A total of 32 children (mean age 9.5±1.2) are covered by the study, with the most important laboratory investigations being performed. All patients undergo abdominal sonography and dynamic kidney scintigraphy following iv administration of 100 μC/kg 99m Tc-DTPA, and glomerular filtration clarence (GFR) measured by the method of full and empty syringe activity. The functional curves are also shown. In children with primary nephrotic syndrome the sonographic imaging reveals enlarged kidney size and enhanced sonogeneity of parenchyma in the first stage. In patients with secondary nephrotic syndrome increased kidney size is likewise observed with enhanced sonogeneity of parenchyma in second stage and unclear visualization of pyramids. In children with idiopathic nephrotic syndrome the scintigraphic data confirm the enlarged kidneys with moderately increased values of GFR. In the mixed forms of nephrotic syndrome the kidneys preserve their moderate enlargement against the background of heterogeneous GFR values. In 5 patients the functional curves show kidney excretion impairment. The study confirms that sonographic imaging correlates well with the dynamic scintigraphic 99m Tc-DTPA imaging in children with nephrotic syndrome. The functional curves and GFR values promote accurate diagnosing and monitoring of the dynamic pathological processes. (author)

Objective: To determine the histological picture and outcome of treatment in cases of childhood nephrotic syndrome who needed renal biopsy. Subjects and Methods: Children suffering from nephrotic syndrome who had atypical features at presentation were initially or late non-responders; frequent relapsers on > 1 mg kg/day and were steroid dependent or frequently relapsed on < 1 mg kg/day but developed steroid toxicity were included. Renal biopsy was performed in these patients. Treatment was administered according to the histopathology reports. Prednisolone 60 mg /m/sup 2//day followed after response by 40 mg /m/sup /2 on alternate days (AD) which was later tapered off. In minimal change nephrotic syndrome (MCNS) with frequent relapses cyclophosphamide, cyclosporine and levimisole were used. For steroid resistant focal segmental glomerulosclerosis (FSGS) intravenous pulses of methylprednisolone and cyclosporine were also given. These patients were followed to see the response of the therapy. Results: The commonest diagnosis was focal segmental glomerulosclerosis (FSGS) (42%) followed by minimal change disease (MCNS) (22%), membranoproliferative or mesangiocapillary glomerulonephritis (MPGN) (14%) and Mesangioproliferative glomerulonephritis (Mes PGN) (12%). There were 6% cases of membranous nephropathy and 4% of diffuse proliferative glomerulonephritis. On presentation, 40% had hematuria, 20% were found to be hypertensive, 12% patients had renal insufficiency and in 40% C3 level was low. Majority of the patients with MPGN and FSGS had atypical features whereas none of the patients with membranous nephropathy had any of these features. Thirty percent cases each of FSGS and MCNS were responders. Among non-responders there were 4 cases of FSGS and one of MPGN. Conclusion: FSGS was the commonest histology in cases of childhood nephrotic syndrome that needed renal biopsy. Highest frequency of atypical features was seen in MPGN and FSGS. (author)

Full Text Available CONTEXT: Etiology of nephrotic syndrome (NS in adults varies depending on the geographical location and is poorly studied in the Indian subcontinent. AIMS: To study the clinical features, biochemical profile and histopathological pattern of various types of glomerulonephritis in adult patients with nephrotic syndrome. METHODS AND MATERIAL: Patients (≥15 years old with nephrotic syndrome presenting to our center and undergoing a kidney biopsy from May 2009 to August 2011 were included for this study. All biopsies were subjected to light microscopy.The histopathological spectrum was analyzed according to the various clinical parameters. STATISTICAL ANALYSIS USED: Analysis was performed using SPSS software version 19.Measures obtained included percentages,medians,correlation coefficients and chi square tests. RESULTS: A total of 50 kidney biopsies were included in analysis. Twenty six(52% patients were male and twenty four(48% patients were female. The average age at presentation was 15-24 years. Among the patients, 22(44% were diagnosed with primary glomerular diseases (PGD and 4(8% with secondary glomerular diseases (SGD. The most common histological lesions was membranous nephropathy(24.4% followed by minimal change disease (MCD (17% and membranous nephropathy (MN (17%. The most common form of SGD was lupus nephritis (LN (10%. Membranous nephropathy and focal segmental glomerulosclerosis were the commonest lesions in males.Among females,membranous nephropathy was the commonest. 31(62% patients were in the age group of 15-34 yrs, 17(34% were in the age group 34- 54yrs and only 2(4% were aged above 55yrs. Among the patients, 6(12% had serum creatinine ≥1.5 mg/dL and 12(24% had either macroscopic or microscopic hematuria. CONCLUSIONS: Membranous nephropathy is still the commonest type of nephrotic syndrome in adults followed closely by focal segmental glomerulosclerosis and minimal change disease as per this study.

A 76-year-old woman suddenly developed anasarca and a fever, and an examination revealed thrombocytopenia, reticulin fibrosis, and acute kidney injury, yielding the diagnosis of TAFRO syndrome. Renal replacement therapy and steroid treatment were soon started. Her proteinuria was minor at first; however, once the kidney function improved, nephrotic syndrome occurred. A kidney biopsy showed membranoproliferative glomerulonephritis-like glomerulopathy with massive macrophage infiltration. Although kidney dysfunction is often observed in TAFRO syndrome patients, its detailed mechanism is unclear. This case suggests that TAFRO syndrome involves both acute kidney injury with minor proteinuria and nephrotic syndrome, and these disorders can develop serially in the same patient.

Full Text Available Renal disorders in pregnancy can be both difficult to diagnose and manage. They are associated with poor maternal and/or fetal outcomes. In pregnancy, proteinuria is common and can range from mild urinary protein elevations to nephrotic levels. The diagnosis of nephrotic syndrome (NS can be challenging, especially in pregnancy as it can be confused with preeclampsia. NS has an incidence of 0.012%–0.025% in pregnant women. It is diagnosed by the presence of more than 3 g/day of proteins in urine, serum albumin <30 g/dL, generalized edema, hypercholesterolemia, and lipiduria. Proteinuria with hypertension is characterized by the presence of hematuria, red cell casts, raised serum creatinine, and features suggestive of systemic disease. Other causes of proteinuria include preeclampsia, diabetes mellitus (Type 1 and Type 2, Immunoglobulin A nephropathy (Ig A glomerulonephritis, focal and segmental glomerulosclerosis, and lupus nephritis. The maternal risks of NS include acute kidney insult, chronic renal failure, gestational hypertension, preeclampsia, and complications due to hypoalbuminemia. Fetal considerations in NS include fetal growth retardation, prematurity, stillbirth, fetal anasarca, and polyhydramnios. Preconception counseling and immunosuppressive drug therapy can improve overall fetomaternal outcome. We hereby present a unique case of successful anesthetic management of NS in a parturient along with concurrent hypothyroidism and hypertension, for elective cesarean section.

Steroid-resistant nephrotic syndrome is characterized by podocyte dysfunction. Drosophila garland cell nephrocytes are podocyte-like cells and thus provide a potential in vivo model in which to study the pathogenesis of nephrotic syndrome. However, relevant pathomechanisms of nephrotic syndrome have not been studied in nephrocytes. Here, we discovered that two Drosophila slit diaphragm proteins, orthologs of the human genes encoding nephrin and nephrin-like protein 1, colocalize within a fingerprint-like staining pattern that correlates with ultrastructural morphology. Using RNAi and conditional CRISPR/Cas9 in nephrocytes, we found this pattern depends on the expression of both orthologs. Tracer endocytosis by nephrocytes required Cubilin and reflected size selectivity analogous to that of glomerular function. Using RNAi and tracer endocytosis as a functional read-out, we screened Drosophila orthologs of human monogenic causes of nephrotic syndrome and observed conservation of the central pathogenetic alterations. We focused on the coenzyme Q 10 (CoQ 10 ) biosynthesis gene Coq2 , the silencing of which disrupted slit diaphragm morphology. Restoration of CoQ 10 synthesis by vanillic acid partially rescued the phenotypic and functional alterations induced by Coq2 -RNAi. Notably, Coq2 colocalized with mitochondria, and Coq2 silencing increased the formation of reactive oxygen species (ROS). Silencing of ND75 , a subunit of the mitochondrial respiratory chain that controls ROS formation independently of CoQ 10 , phenocopied the effect of Coq2 -RNAi. Moreover, the ROS scavenger glutathione partially rescued the effects of Coq2 -RNAi. In conclusion, Drosophila garland cell nephrocytes provide a model with which to study the pathogenesis of nephrotic syndrome, and ROS formation may be a pathomechanism of COQ2 -nephropathy.

2007-01-01

To assess the value of single voided random (spot) urinary protein to creatinine ratio in accurately predicting the 24-hour urinary protein excretion in Pakistani pediatric population with nephrotic syndrome. Fifty seven children between 1-18 years with nephrotic syndrome were included. Seventy pairs of spot urine (5 milliliter) and 24-hour urine were collected in different phases of their disease e.g. initial, induction and remission. The protein to creatinine ratio was determined in spot urine samples and total protein content in 24-hour urine samples. The correlation between the ratio and 24-hour urinary protein excreted was determined using Pearson's coefficient (r) linear regression analysis. The protein to creatinine ratio in a spot urine sample was significantly correlated with the 24-hour urinary protein. The correlation coefficient (least square method) was found to be significant (r=0.9444). A random (spot) urinary protein to creatinine ratio of greater than 2 correlated well with the massive proteinuria (i.e. nephrotic syndrome), between 2 to 0.2 indicated glomerulopathy while a ratio of less than 0.2 was suggestive of physiological values. The random spot urinary protein to creatinine ratio can reliably be used to assess the degree of proteinuria in children with nephrotic syndrome and can replace the 24-hour urinary protein excretion/collection.

Neuromyelitis optica (NMO) associated with nephrotic syndrome and autoimmune-related pancytopenia has not been reported previously. We report herein a young woman who initially presented with bilateral blurring of vision and numbness in her hands. MRI disclosed multiple white matter lesions and a long cervical spinal cord lesion extending to the medulla oblongata. Serum aquaporin-4 antibody was positive and the patient was diagnosed with NMO. While in the hospital, she presented with hypoproteinemia and heavy proteinuria, meeting the diagnostic criteria of nephrotic syndrome. After high-dose methylprednisolone treatment, her vision improved significantly and urine protein quantity decreased. However, the patient subsequently developed severe pancytopenia with a positive Coombs' test. Thrombocytopenia finally led to uncontrollable gastrointestinal bleeding as the direct cause of the patient's death. This case illustrates the extremely rare condition of concurrence of NMO, nephrotic syndrome, and autoimmune pancytopenia in one patient, which suggests the involvement of organs beyond the central nervous system in NMO spectrum disorders.

Nephrotic Syndrome and Acute Renal Failure Apparently Induced by Sunitinib

Directory of Open Access Journals (Sweden)

Ying-Shou Chen

2009-10-01

Full Text Available We report a case of nephrotic syndrome and acute renal failure apparently induced by sunitinib. A 67-year-old man with a history of metastatic renal cell carcinoma presented with progressive kidney dysfunction with proteinuria, general edema, and body weight gain of 21 kg after undergoing 3 weeks of sunitinib therapy. The patient had taken no other over-the-counter medications, and all other possible causes of nephrotic syndrome were excluded. The Naranjo Adverse Drug Reaction Probability Scale score for this event was 6, indicating a high probability that the observed presentations were associated with use of the drug. However, despite the discontinuation of sunitinib, his condition deteriorated, and hemodialysis was initiated for respiratory distress. A renal biopsy was performed, which revealed ischemic acute tubular necrosis with minimal change nephropathy. In conclusion, nephrologists and oncologists should be aware that nephrotic syndrome with ischemic acute tubular necrosis is a possible adverse effect of sunitinib. For early diagnosis of this condition and to avoid renal damage, we recommend differential diagnosis of serum creatinine and proteinuria in patients undergoing sunitinib therapy.

Full Text Available Background: Nephrotic syndrome (NS is a kidney disease that is most often found in children. Hypoalbuminemia in NS can cause a decrease in oncotic pressure causing extravasation of fluid into the interstitial space. In conditions of severe hypoalbuminemia, fluid extravasation may cause occurrence of pleural effusion. The objectives of this study was to analyze the correlation between hypoalbuminemia and pleural effusion in children with NS. Methods: An analytical study was conducted on 69 medical records of pediatric nephrotic syndrome from 1 January 2008–31 December 2013 in dr. Hasan Sadikin General Hospital. Inclusion criteria were pediatric patients between 1-14 years old with NS. Exclusion criteria were patients who already had albumin transfusion, malnutrition, patients with chronic disease, and incomplete medical record information. Contingency coefficient test was carried out to discover the correlation between variables. Results: Out of 89 samples, 69 samples were included. Characteristics of the included patients are male (n=48, female (n=21, age 1–5 (n=24, 6–10 (n=22, 11–14 (n=23, mild hypoalbuminemia (n=3, moderate hypoalbuminemia (n=27, severe hypoalbuminemia (n=39, patients with pleural effusion (n=23, and non-pleural effusion (n=46. There was a significant correlation between  hypoalbuminemia and pleural effusion with p=0.000 (p<0.05 and moderate correlation (r=0.437. Conclusions: Hypoalbuminemia has correlation with pleural effusion in pediatric nephrotic syndrome.

Steroid-resistant nephrotic syndrome is a rare kidney disease involving either immune-mediated or genetic alterations of podocyte structure and function. The rare nature, heterogeneity, and slow evolution of the disorder are major obstacles to systematic genotype-phenotype, intervention, and outcome studies, hampering the development of evidence-based diagnostic and therapeutic concepts. To overcome these limitations, the PodoNet Consortium has created an international registry for congenital nephrotic syndrome and childhood-onset steroid-resistant nephrotic syndrome. Since August of 2009, clinical, biochemical, genetic, and histopathologic information was collected both retrospectively and prospectively from 1655 patients with childhood-onset steroid-resistant nephrotic syndrome, congenital nephrotic syndrome, or persistent subnephrotic proteinuria of likely genetic origin at 67 centers in 21 countries through an online portal. Steroid-resistant nephrotic syndrome manifested in the first 5 years of life in 64% of the patients. Congenital nephrotic syndrome accounted for 6% of all patients. Extrarenal abnormalities were reported in 17% of patients. The most common histopathologic diagnoses were FSGS (56%), minimal change nephropathy (21%), and mesangioproliferative GN (12%). Mutation screening was performed in 1174 patients, and a genetic disease cause was identified in 23.6% of the screened patients. Among 14 genes with reported mutations, abnormalities in NPHS2 (n=138), WT1 (n=48), and NPHS1 (n=41) were most commonly identified. The proportion of patients with a genetic disease cause decreased with increasing manifestation age: from 66% in congenital nephrotic syndrome to 15%-16% in schoolchildren and adolescents. Among various intensified immunosuppressive therapy protocols, calcineurin inhibitors and rituximab yielded consistently high response rates, with 40%-45% of patients achieving complete remission. Confirmation of a genetic diagnosis but not the

Up-regulation of hepatic Acyl CoA: Diacylglycerol acyltransferase-1 (DGAT-1) expression in nephrotic syndrome.

Nephrotic syndrome is associated with hypercholesterolemia, hypertriglyceridemia, and marked elevations of plasma low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL). Hypertriglyceridemia in nephrotic syndrome is accompanied by increased hepatic fatty acid synthesis, elevated triglyceride secretion, as well as lipoprotein lipase, VLDL-receptor, and hepatic triglyceride lipase deficiencies, which lead to impaired clearance of triglyceride-rich lipoproteins. Acyl CoA: diacylglycerol acyltransferase (DGAT) is a microsomal enzyme that joins acyl CoA to 1, 2-diacylglycerol to form triglyceride. Two distinct DGATs (DGAT-1 and DGAT2) have recently been identified in the liver and other tissues. The present study tested the hypothesis that the reported increase in hepatic triglyceride secretion in nephrotic syndrome may be caused by up-regulation of DGAT. Male Sprague-Dawley rats were rendered nephrotic by two sequential injections of puromycin aminonucleoside (130 mg/kg on day 1 and 60 mg/kg on day 14) and studied on day 30. Placebo-treated rats served as controls. Hepatic DGAT-1 and DGAT-2 mRNA abundance and enzymatic activity were measured. The nephrotic group exhibited heavy proteinuria, hypoalbuminemia, hypercholesterolemia, hypertriglyceridemia, and marked elevation of VLDL concentration. Hepatic DGAT-1 mRNA, DGAT-1, and total DGAT activity were significantly increased, whereas DGAT-2 mRNA abundance and activity were unchanged in the nephrotic rats compared to the control animals. The functional significance of elevation of DGAT activity was illustrated by the reduction in microsomal free fatty acid concentration in the liver of nephrotic animals. Nephrotic syndrome results in up-regulation of hepatic DGAT-1 expression and activity, which can potentially contribute to the associated hypertriglyceridemia by enhancing triglyceride synthesis. Thus, it appears that both depressed catabolism and increased synthetic capacity contribute to

Full Text Available Samuel N Uwaezuoke Department of Pediatrics, Pediatric Nephrology Firm, University of Nigeria Teaching Hospital, Ituku-Ozalla, Enugu, Nigeria Abstract: Two histological subtypes of idiopathic nephrotic syndrome are commonly recognized in children, namely minimal change nephropathy and focal segmental glomerulosclerosis. Children with minimal change nephropathy (the majority of whom are steroid-sensitive and focal segmental glomerulosclerosis (the majority of whom are steroid-resistant require early identification in order to ensure appropriate therapeutic intervention and better outcome. Although renal biopsy and histology remain the ideal diagnostic steps to identify these histological subtypes, reports indicate that serum and urinary biomarkers are now being utilized in the investigation of childhood idiopathic nephrotic syndrome. This paper aims to review the diagnostic and prognostic utility of novel biomarkers in childhood idiopathic nephrotic syndrome and to highlight their role in differentiating steroid-sensitive nephrotic syndrome (SRNS from steroid-resistant nephrotic syndrome (SSNS. Using the terms “idiopathic nephrotic syndrome,” “children,” and “biomarkers” the PubMed database was searched for relevant studies related to the topic. Biomarkers such as adiponectin, neopterin, β2-microglobulin, and N-acetyl-β-D glucosaminidase were reported as diagnostic markers. In addition to neopterin and N-acetyl-β-D glucosaminidase, urine vitamin D-binding protein and α1β-glycoprotein were shown to differentiate SRNS from SSNS while N-acetyl-β-D glucosaminidase and β2-microglobulin could predict steroid responsiveness and renal outcome in SRNS. Although progress has been made in demonstrating the diagnostic and prognostic utility of these biomarkers, their limited availability in most laboratories has precluded a complete paradigm shift from the conventional renal biopsy. Nevertheless, further longitudinal studies are required

Unusual pediatric co-morbility: autoimmune thyroiditis and cortico-resistant nephrotic syndrome in a 6-month-old Italian patient

Directory of Open Access Journals (Sweden)

Urbano Flavia

2012-10-01

Full Text Available Abstract We report on a case of autoimmune thyroiditis in a 6-month-old patient with cortico-resistant nephrotic syndrome. Normal serum levels of thyroid hormons and thyroid-stimulating hormone were detected with high titers of circulant antithyroid antibodies and a dysomogeneous ultrasound appearance of the gland, typical of autoimmune thyroiditis. The research of maternal thyroid antibodies was negative. This is the first case of autoimmune thyroiditis found in such a young patient with pre-existing nephrotic syndrome ever described in literature. This association is random because nephrotic syndrome does not have an autoimmune pathogenesis and the genes involved in autoimmune thyroiditis are not related to those of nephrotic syndrome.

History of Nephrotic Syndrome and Evolution of its Treatment

Full Text Available The recognition, evaluation, and early treatment of nephrotic syndrome in infants and children originates from physicians dating back to Hippocrates. It took nearly another thousand years before the condition was described for its massive edema requiring treatment with herbs and other remedies. A rich history of observations and interpretations followed over the course of centuries until the recognition of the combination of clinical findings of foamy urine, swelling of the body, and measurements of urinary protein and blood analyses showed the phenotypic characteristics of the syndrome that were eventually linked to the early anatomic descriptions from first kidney autopsies and then renal biopsy analyses. Coincident with these findings were a series of treatment modalities involving the use of natural compounds to a host of immunosuppressive agents that are applied today. With the advent of molecular and precision medicine, the field is poised to make major advances in our understanding and effective treatment of nephrotic syndrome and prevent its long-term sequelae.

Full Text Available BACKGROUND Nephrotic syndrome is a disease affecting the renal system. Most paediatricians will invariably encounter children with nephrotic syndrome in their clinic. The disease is characterised by the presence of oedema, persistent heavy proteinuria, hypoproteinaemia and hypercholesterolaemia. The disease is influenced by factors like age, geography, race and also has certain genetic influence related to HLA (DR7, B12, B8. In children, minimal change nephrotic syndrome is the most common variant of primary nephrotic syndrome. It accounts to more than eighty per cent of the cases seen children under seven years whereas it has a chance of fifty per cent in the age group of seven to sixteen years. Males are affected two times higher compared to females. The parents usually bring the child to the hospital with signs of oedema. Usually, the child recovers with treatment, but in some cases, there can be relapse. MATERIALS AND METHODS  The study was conducted in the Department of Paediatrics, Travancore Medical College, Kollam.  The study was done from January 2015 to January 2016.  Sixty cases were identified and were chosen for the study. INCLUSION CRITERIA 1. Steroid sensitive cases of nephrotic syndrome. 2. Age less than twelve years. 3. Admitted cases. EXCLUSION CRITERIA 1. Steroid-resistant and steroid-dependent cases. 2. Age more than twelve years. 3. Outpatient cases. RESULTS Out of the sixty cases studied, forty one cases belonged to male sex and nineteen cases belonged to female sex. Based on the age group, maximum number of cases belonged to age group four to eight years, which amounted to thirty four cases followed by age group eight to twelve years, which amounted to eighteen cases. Age group zero to four years had the least number of cases, which amounted to eight in number. Based on clinical signs and symptoms, fifty five cases presented with oedema either periorbital, scrotal or pedal oedema. Ten cases presented with fever

Children with Idiopathic Nephrotic Syndrome (INS) are at risk of hearing loss due to the adverse impact of medications and related immunological and genetic factors on both cochlea and kidney. So this work was planned to evaluate hearing status in children with INS and to clarify the possible associated risk factors by interpreting the clinical and laboratory profiles of those children. Ninety children with INS aged 5-14 years [30 patients with steroid-sensitive nephrotic syndrome (SSNS), 30 patients with steroid dependent/frequently relapsing nephrotic syndrome (SDNS/FRNS), and 30 patients with steroid-resistant nephrotic syndrome (SRNS)], and 90 age and sex matched normal controls were enrolled into this study. Laboratory measurements of serum calcium, creatinine, cholesterol, blood urea and other relevant investigations were done. Pure tone audiometry was done with the sensory-neural hearing loss (SNHL) diagnosed when the level bone conduction was >20 dB and the difference in air to the bone gap was children with INS had SNHL, mostly of mild degree HL and primarily occurred at the lower frequencies. A highly significant statistical difference between controls and various types of nephrotic syndrome regarding pure tone audiometry measurements at frequencies 250, 500, 1000 Hz, whereas insignificant difference interpreting pure tone audiometry measurements in 2000, 4000 and 8000 Hz. Children with different phenotypes of nephrotic syndrome are at risk of sensorineural hearing impairment. The hazards associated with this impairment were higher blood pressure, hypercholesterolemia, hypoalbuminemia, and hypocalcemia. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Tregs infusion reverts proteinuria and reduces renal lesions in most animal models of nephrotic syndrome (i.e. Buffalo/Mna, Adriamycin, Promycin, LPS. IL2 up-regulates Tregs and may be an alternative to cell-therapy in this setting. To evaluate a potential role of IL2 as Tregs inducer and proteinuria lowering agent in human nephrotic syndrome we treated 5 nephrotic patients with 6 monthly cycles of low-dose IL2 (1x106 U/m2 first month, 1.5x106 U/m2 following months. The study cohort consisted of 5 children (all boys, 11–17 years resistant to all the available treatments (i.e. steroids, calcineurin inhibitors, mycophenolate, Rituximab. Participants had Focal Segmental Glomerulosclerosis (3 cases or Minimal Change Nephropathy (2 cases. IL2 was safe in all but one patient who had an acute asthma attack after the first IL2 dose and did not receive further doses. Circulating Tregs were stably increased (>10% during the whole study period in 2 cases while were only partially modified in the other two children who started with very low levels and partially responded to single IL2 Proteinuria and renal function were not modified by IL2 at any phase of the study. We concluded that low-dose IL2 given in monthly pulses is safe and modifies the levels of circulating Tregs. This drug may not be able to lower proteinuria or affect renal function in children with idiopathic nephrotic syndrome. We were unable to reproduce in humans the effects of IL2 described in rats and mice reducing de facto the interest on this drug in nephrotic syndrome.ClinicalTrials.gov NCT02455908.

Full Text Available  Minimal Change Disease (MCD is the leading cause of childhood Nephrotic Syndrome (NS. Therefore in pediatrics nephrotic syndrome, most children beyond the first year of life will be treated with corticosteroids without an initial biopsy. Children with NS often display a number of calcium homeostasis disturbances causing abnormal bone histology, including hypocalcemia, reduced serum vitamin D metabolites, impaired intestinal absorption of calcium, and elevated levels of immunoreactive parathyroid hormone (iPTH. These are mainly attributed to the loss of a variety of plasma proteins and minerals in the urine as well as steroid therapy. Early diagnosis and management of these abnormalities, could prevent the growth retardation and renal osteodystrophy that affects children with nephrotic syndrome. Here we reviewed the literature for changes of calcium and vitamin D metabolism in nephrotic syndrome and its consequences on bones, also the effect of corticosteroid and possible preventive strategies that could be done to avoid long term outcomes in children. Although the exact biochemical basis for Changes in levels of calcium and vitamin D metabolites in patients with NS remains speculative; Because of the potential adverse effects of these changes among growing children, widespread screening for vitamin D deficiency or routine vitamin D supplementation should be considered.

Minimal change nephrotic syndrome in an 82 year old patient following a tetanus-diphteria-poliomyelitis-vaccination

Full Text Available Abstract Background The most common cause of idiopathic nephrotic syndrome in children and younger adults is the minimal change nephrotic syndrome (MCNS. In the elderly MCNS is relatively uncommon. Over the last decade some reports suggest a rare but possible association with the administration of various vaccines. Case presentation A 82-year old Caucasian female presented with pronounced nephrotic syndrome (proteinuria of 7.1 g/d, hypoproteinemia of 47 g/l. About six weeks prior to admission, she had received a combination vaccination for tetanus, diphtheria and poliomyelitis as a booster-vaccination from her general practitioner. The renal biopsy revealed typical minimal change lesions. She responded well to the initiated steroid treatment. As through physical examination as well as extensive laboratory and imaging studies did neither find any evidence for malignancies nor infections we suggest that the minimal change nephrotic syndrome in this patient might be related to the activation of the immune system triggered by the vaccination. Conclusion Our case as well as previous anecdotal reports suggests that vaccination and the resulting stimulations of the immune system might cause MCNS and other severe immune-reactions. Increased awareness in that regard might help to expand the database of those cases.

Low molecular weight heparin (LMWH) has a structure similar to heparan sulfate, which exerts anti‑inflammatory effects via inhibiting elastase (Ela) activity. Release of Ela along the glomerular capillary wall may induce glomerular injury and proteinuria. The present study aimed to investigate the influence of LMWH on steroid‑sensitive nephrotic syndrome (SSNS) and the potential underlying mechanism. A total of 40 SSNS patients and 20 healthy controls were recruited. SSNS patients were treated with LMWH and prednisone simultaneously (LMWH+pred group) or with prednisone alone (pred group). Proteinuria, urinary glycosaminoglycans (GAGs), serum Ela and urinary creatinine levels were measured. The nephrotic period of SSNS was 15.93±5.78 days. The nephrotic period of SSNS in LMWH+pred group was significantly reduced compared with the pred group (14.13±4.56 vs. 18.63±6.49 days; PEla levels (77.64±10.99 ng/l) were significantly greater in the nephrotic period of SSNS compared with the remission period (0.107±0.026 g/24 h, 1.53±0.27 mg/mmol Cr and 41.92±7.81 ng/l, respectively) and the healthy control group (0.098±0.027 g/24 h, 1.40±0.26 mg/mmol creatinine and 38.43±9.83 ng/l, respectively; PEla levels in the LMWH+pred group were significantly reduced compared with the pred group (P0.05). Positive correlations were revealed between urinary GAG excretion and proteinuria (r=0.877; PEla levels (r=0.844; PEla levels and urinary GAG excretion (r=0.881; PEla levels may induce proteinuria by degrading GAGs in the glomerular basement membrane in children with SSNS. LMWH may benefit nephrotic remission of SSNS via inhibiting Ela.

To investigate the clinical features of complicated with pulmonary embolism nephrotic syndrome in children. 99m Tc-MAA pulmonary perfusion imaging was performed on 30 nephrotic syndrome in children with elevated plasma D-dimer. Results shown that 14 of 30 patients were found to have pulmonary embolism (46.7%). Pulmonary perfusion imaging showed an involvement of 1 pulmonary segment in 3 cases, 2 segments in 2 cases and over 3 segments in other 9 cases. Among them, there were 7 segments involved in one case. After two weeks of heparin anti-coagulative therapy, most cases showed a recovery. The result of this study suggested that pulmonary embolism is a common complication of nephrotic syndrome. Pulmonary perfusion imaging is simple, effective and accurate method for the diagnosis of pulmonary embolism, and it also can help to assess the value of clinical therapy

Forced expression of laminin beta1 in podocytes prevents nephrotic syndrome in mice lacking laminin beta2, a model for Pierson syndrome.

Pierson syndrome is a congenital nephrotic syndrome with ocular and neurological defects caused by mutations in LAMB2, the gene encoding the basement membrane protein laminin β2 (Lamβ2). It is the kidney glomerular basement membrane (GBM) that is defective in Pierson syndrome, as Lamβ2 is a component of laminin-521 (LM-521; α5β2γ1), the major laminin in the mature GBM. In both Pierson syndrome and the Lamb2(-/-) mouse model for this disease, laminin β1 (Lamβ1), a structurally similar homolog of Lamβ2, is marginally increased in the GBM, but it fails to fully compensate for the loss of Lamβ2, leading to the filtration barrier defects and nephrotic syndrome. Here we generated several lines of Lamβ1 transgenic mice and used them to show that podocyte-specific Lamβ1 expression in Lamb2(-/-) mice abrogates the development of nephrotic syndrome, correlating with a greatly extended lifespan. In addition, the more Lamβ1 was expressed, the less urinary albumin was excreted. Transgenic Lamβ1 expression increased the level of Lamα5 in the GBM of rescued mice, consistent with the desired increased deposition of laminin-511 (α5β1γ1) trimers. Ultrastructural analysis revealed occasional knob-like subepithelial GBM thickening but intact podocyte foot processes in aged rescued mice. These results suggest the possibility that up-regulation of LAMB1 in podocytes, should it become achievable, would likely lessen the severity of nephrotic syndrome in patients carrying LAMB2 mutations.

Late Onset Cobalamin Disorder and Hemolytic Uremic Syndrome: A Rare Cause of Nephrotic Syndrome

Directory of Open Access Journals (Sweden)

Gianluigi Ardissino

2017-01-01

Full Text Available Hemolytic uremic syndrome (HUS is an unrare and severe thrombotic microangiopathy (TMA caused by several pathogenetic mechanisms among which Shiga toxin-producing Escherichia coli infections and complement dysregulation are the most common. However, very rarely and particularly in neonates and infants, disorders of cobalamin metabolism (CblC can present with or be complicated by TMA. Herein we describe a case of atypical HUS (aHUS related to CblC disease which first presented in a previously healthy boy at age of 13.6 years. The clinical picture was initially dominated by nephrotic range proteinuria and severe hypertension followed by renal failure. The specific treatment with high dose of hydroxycobalamin rapidly obtained the remission of TMA and the complete recovery of renal function. We conclude that plasma homocysteine and methionine determinations together with urine organic acid analysis should be included in the diagnostic work-up of any patient with TMA and/or nephrotic syndrome regardless of age.

Background and objectives Therapeutic drug monitoring of mycophenolic acid can improve clinical outcome in organ transplantation and lupus, but data are scarce in idiopathic nephrotic syndrome. The aim of our study was to investigate whether mycophenolic acid pharmacokinetics are associated with disease control in children receiving mycophenolate mofetil for the treatment of steroid–dependent nephrotic syndrome. Design, setting, participants, & measurements This was a retrospective multicenter study including 95 children with steroid–dependent nephrotic syndrome treated with mycophenolate mofetil with or without steroids. Area under the concentration-time curve of mycophenolic acid was determined in all children on the basis of sampling times at 20, 60, and 180 minutes postdose, using Bayesian estimation. The association between a threshold value of the area under the concentration-time curve of mycophenolic acid and the relapse rate was assessed using a negative binomial model. Results In total, 140 areas under the concentration-time curve of mycophenolic acid were analyzed. The findings indicate individual dose adaptation in 53 patients (38%) to achieve an area under the concentration-time curve target of 30–60 mg·h/L. In a multivariable negative binomial model including sex, age at disease onset, time to start of mycophenolate mofetil, previous immunomodulatory treatment, and concomitant prednisone dose, a level of area under the concentration-time curve of mycophenolic acid >45 mg·h/L was significantly associated with a lower relapse rate (rate ratio, 0.65; 95% confidence interval, 0.46 to 0.89; P=0.01). Conclusions Therapeutic drug monitoring leading to individualized dosing may improve the efficacy of mycophenolate mofetil in steroid–dependent nephrotic syndrome. Additional prospective studies are warranted to determine the optimal target for area under the concentration-time curve of mycophenolic acid in this population. PMID:27445161

Familial Mediterranean fever, Inflammation and Nephrotic Syndrome: Fibrillary Glomerulopathy and the M680I Missense Mutation

Directory of Open Access Journals (Sweden)

Semerdjian Ronald J

2003-08-01

Full Text Available Abstract Background Familial Mediterranean fever (FMF is an autosomal recessive disease characterized by inflammatory serositis (fever, peritonitis, synovitis and pleuritis. The gene locus responsible for FMF was identified in 1992 and localized to the short arm of chromosome 16. In 1997, a specific FMF gene locus, MEFV, was discovered to encode for a protein, pyrin that mediates inflammation. To date, more than forty missense mutations are known to exist. The diversity of mutations identified has provided insight into the variability of clinical presentation and disease progression. Case Report We report an individual heterozygous for the M680I gene mutation with a clinical diagnosis of FMF using the Tel-Hashomer criteria. Subsequently, the patient developed nephrotic syndrome with biopsy-confirmed fibrillary glomerulonephritis (FGN. Further diagnostic studies were unremarkable with clinical workup negative for amyloidosis or other secondary causes of nephrotic syndrome. Discussion Individuals with FMF are at greater risk for developing nephrotic syndrome. The most serious etiology is amyloidosis (AA variant with renal involvement, ultimately progressing to end-stage renal disease. Other known renal diseases in the FMF population include IgA nephropathy, IgM nephropathy, Henoch-Schönlein purpura as well as polyarteritis nodosa. Conclusion To our knowledge, this is the first association between FMF and the M680I mutation later complicated by nephrotic syndrome and fibrillary glomerulonephritis.

Steroid-sensitive nephrotic syndrome (SSNS) is classically thought to be a T-cell disorder. The aim of this study was to examine whether or not thymus homeostasis was affected in SSNS. Mature and naive T cell recent thymic emigrants were quantified in the peripheral blood of nephrotic patients and controls. Because the generation of new T cells by the thymus ultimately depends on hematopoietic stem cells, CD34+ cells were also included in the study. Nineteen patients with SSNS during relapse, 13 with SSNS during proteinuria remission, and 18 controls were studied. Cell-surface markers (CD3, CD4, CD8, CD19, CD16, CD56, CD45RA, CD62L, CD34, and CD38) were analyzed by flow cytometric analysis. T-cell rearrangement excision circles (TRECs) were quantified in CD2+ cells by real-time polymerase chain reaction. Stroma cell-derived factor-1 (SDF-1) genotype and metalloproteinase-9 (MMP-9) plasma levels were also determined. Mature T cells (CD4+ and CD8+), circulating naive T cells (CD62L+ and CD3+ CD62L+), and recent thymic emigrants (CD45RA+) as well as TRECs, that measure thymus production, had a similar level in the three groups of patients. Conversely, CD34+ hematopoietic stem cells displayed a two-fold increase in SSNS patients during relapse either compared with controls or SSNS patients at remission. In addition, compared with controls, SSNS patients at remission displayed (1) a decrease in CD19+ cells (B cells) and (2) an increase in CD16CD56+ cells [natural killer (NK) cells]. In conclusion, thymus homeostasis is not significantly affected in nephrotic patients. Hematopoietic stem-cell mobilization at proteinuria relapse, as well as changes in B and NK cells during remission, suggest that SSNS might be due to a general disturbance of hematopoietic and immune cell trafficking.

Nephrotic syndrome in primary myelofibrosis with renal extramedullary hematopoiesis and glomerulopathy in the JAK inhibitor era.

Primary myelofibrosis (PMF) is an uncommon form of myeloproliferative neoplasm (MPN) characterized by a proliferation of predominantly megakaryocytes and granulocytes in the bone marrow that, in fully-developed disease, is associated with reactive deposition of fibrous connective tissue, extramedullary hematopoiesis (EMH), and splenomegaly. Kidney involvement is rare and clinically presents with proteinuria, nephrotic syndrome, and renal insufficiency. Renal damage can be due to EMH and glomerulopathy. Renal EMH presents three patterns: infiltration of the interstitium with possible renal failure caused by functional damage of parenchyma and vessels, infiltration of capsule and pericapsular adipose tissue, and sclerosing mass-like lesions that can cause hydronephrosis and hydroureter with obstructive uropathy and renal failure. Glomerulopathy associated with PMF is rarely described, ranging from 1 month to 18 years from diagnosis of the neoplasm to renal biopsy. It is characterized by expansion and hypercellularity mesangial, segmental sclerosis, features of chronic thrombotic microangiopathy (TMA), and intracapillary hematopoietic cells infiltrating in absence of immune-mediated glomerulonephritis. We present a nephrotic syndrome in PMF-related glomerulopathy, associated with EMH, without renal failure, in a patient under treatment for 2 years with JAK2 inhibitor ruxolitinib. Despite treatment, the patient died 7 months after renal biopsy. Nephrologists still know very little about this topic and there is no homogeneous data about incidence, pathogenesis, and optimal treatment of this poor prognostic PMF-associated nephrotic syndrome. We focus on data in the literature in the hope of stimulating hematologists, nephrologists, pathologists to future studies about the natural history of renal involvement, useful for optimal management of this rare pathology.

Relapses of nephrotic syndrome often follow minor infections, commonly of the upper respiratory tract. Daily administration of maintenance prednisolone during intercurrent infections was examined to determine whether the treatment reduces relapse rates in children with frequently relapsing nephrotic syndrome. In a randomized controlled trial (nonblind, parallel group, tertiary-care hospital), 100 patients with idiopathic, frequently relapsing nephrotic syndrome eligible for therapy with prolonged low-dose, alternate-day prednisolone with or without levamisole were randomized to either receive their usual dose of alternate-day prednisolone daily for 7 days during intercurrent infections (intervention group) or continue alternate-day prednisolone (controls). Primary outcome was assessed by comparing the rates of infection-associated relapses at 12-month follow-up. Secondary outcomes were the frequency of infections and the cumulative amount of prednisolone received in both groups. Patients in the intervention group showed significantly lower infection-associated (rate difference, 0.7 episodes/patient per year; 95% confidence intervals [CI] 0.3, 1.1) and lower total relapse rates (0.9 episodes/patient per year, 95% CI 0.4, 1.4) without increase in steroid toxicity. Poisson regression, adjusted for occurrence of infections, showed that daily administration of prednisolone during infections independently resulted in 59% reduction in frequency of relapses (rate ratio, 0.41; 95% CI 0.3, 0.6). For every six patients receiving this intervention, one showed a reduction of relapse frequency to less than three per year. Daily administration of maintenance doses of prednisolone, during intercurrent infections, significantly reduces relapse rates and the proportion of children with frequently relapsing nephrotic syndrome.

Full Text Available BACKGROUND Nephrotic syndrome occurs when the filtering units of the kidneys- the glomeruli are damaged. The annual incidence of nephrotic syndrome ranges from 2-7 per 100,000 children. Oral corticosteroids form the cornerstone for management of most children with nephrotic syndrome. Long-term steroid therapy in childhood is associated with a number of significant adverse effectsmajor ophthalmic adverse effects include decreased vision, recurrent hordeolum, posterior subcapsular cataract, pseudotumour cerebri, visual hallucinations. This study aims to analyse the ocular findings in children with nephrotic syndrome, and their treatment related ocular abnormalities. MATERIALS AND METHODS This is a cross sectional study, conducted at The Department of Ophthalmology, Government Medical College Thrissur of 1-year duration. Study participants include patients who attended outpatient department of Paediatrics, Govt. Medical College, Thrissur, with clinical and objective investigational evidence of nephrotic syndrome. 70 children who were included in the study were interviewed with a questionnaire; Detailed history was taken from the patients and their parents, regarding the onset of the disease, treatment details, year of starting steroids, history of hypertension, additional drugs, history of defective vision, headache, allergic diseases of eye, eyelid swellings and use of spectacles. Visual acuity was assessed with Snellen s’ chart. Best corrected visual acuity was noted. Acuity was also measured with spectacles if the child was wearing them. Anterior segment was examined under torchlight and later in slit lamp and in all cases fundus examination and retinoscopy were done after dilating pupils with homatropine. Intraocular pressure was measured with Goldman Applanation Tonometer. RESULTS Since the sample size is small, the exact sex distribution cannot be ascertained. History of headache was present in 45 children (64.3%. Visual acuity was assessed

There is evidence pointing to a decrease of the glomerular filtration rate (GFR) in a subgroup of nephrotic children, likely secondary to hypovolemia. The aim of this study is to validate the use of urinary potassium to the sum of potassium plus sodium ratio (UK/UK+UNa) as an indicator of hypovolemia in nephrotic syndrome, enabling detection of those patients who will benefit from albumin infusion. We prospectively studied 44 nephrotic children and compared different parameters to a control group (36 children). Renal perfusion and glomerular permeability were assessed by measuring clearance of para-aminohippurate and inulin. Vaso-active hormones and urinary sodium and potassium were also measured. Subjects were grouped into low, normal, and high GFR groups. In the low GFR group, significantly lower renal plasma flow (p = 0.01), filtration fraction (p = 0.01), and higher UK/UK+UNa (p = 0.03) ratio were noted. In addition, non-significant higher plasma renin activity (p = 0.11) and aldosteron (p = 0.09) were also seen in the low GFR group. A subgroup of patients in nephrotic syndrome has a decrease in glomerular filtration, apparently related to hypovolemia which likely can be detected by a urinary potassium to potassium plus sodium ratio > 0.5-0.6 suggesting benefit of albumin infusion in this subgroup. What is Known: • Volume status can be difficult to assess based on clinical parameters in nephrotic syndrome, and albumin infusion can be associated with development of pulmonary edema and fluid overload in these patients. What is New: • Urinary potassium to the sum of urinary potassium plus sodium ratio can accurately detect hypovolemia in nephrotic syndrome and thus identify those children who would probably respond to albumin infusion.

Full Text Available Introduction: Nephrotic syndrome is a clinical picture characterized by severe proteinuria, hypoalbuminemia, edema and hypercholesterolemia. A retrospective study was carried out in order to describe disease pattern in newly diagnosed nephrotic syndrome of children admitted to Tripoli children hospital during the year 2014. Methods: The medical data of 56 patients aged between 1 year and 11 years diagnosed with idiopathic nephrotic syndrome were analysed using SPSS software. The data included gender differences, sensitivity to steroid therapy, relapses during six months of follow up and the effect of variable factors such as family history, hypertension, hematuria, serum urea on the degree of relapse. Results: Out of 56 patients with newly diagnosed nephrotic syndrome (NS, 60.7% were boys and 39.3% were girls, with a mean age 4.2±2.2 years. Age  was related significantly to the response to steroid therapy, where 79.5% of patients aged between 2-8 years (group 1 had steroid sensitive nephrotic syndrome (SSNS compared with only 41.7% of patients aged less than 2 years or more than 8 years (group 2  (P<0.001.  Although girls relapsed more than boys (70.5% versus 57.1% during six months of therapy, this difference was not statistically significant. Similarly, no other factors measured such as family history of NS, hypertension, hematuria, serum complement and urea had any effect on the percentage of relapse in patients with newly diagnosed NS.  Conclusion: NS is one of the commonest reasons for admission to nephrology ward. It is more common in boys than girls. The age at presentation related significantly to the response to steroidal therapy. Regarding relapses, girls seems to relapse more frequent than boys and relapses was seen more in age group 1 than group 2, however, these differences were not significant. Other factors studied seems to have no effect on the relapse rate of children with newly diagnosed NS. Key-words:  Idiopathic

Full Text Available The developing world is observing changing histopathological patterns of idiopathic nephrotic syndrome (INS. However, the true burden of non-minimal change disease (non-MCD presenting as INS remains unestimated owing to a paucity of data on renal biopsies. Data were collected from January 2006 to June 2014 on 75 children up to 16 years of age who underwent renal biopsies for INS. Mean age at biopsy was 11.2 ± 3.7 years. The male to female ratio was 1.5:1. A total of 25 (33.3% children were steroid sensitive, 36 (48% were steroid resistant, 10 (13.3% were steroid dependent and 4 (5.3% came with relapse of nephrotic syndrome (NS. Focal segmental glomerulosclerosis (FSGS was the most common histopathological subtype observed in 35 (46.8% children followed by membranous glomerulonephritis (MGN in 11 (14.7%, membranoproliferative glomerulonephritis (MPGN and mesangioproliferative glomerulonephritis (MSGN in 4 (5.3% each and IgA nephropathy in one (1.3%. MCD was the histological lesion in 19 (25.3% children. The histopathology established FSGS as the main underlying cause of steroid resistant NS. The study highlights the emergence of non-MCD as the common cause of INS in the pediatric population and signifies the importance of renal biopsies in children with INS.

Rituximab could be an effective treatment for childhood-onset, complicated, frequently relapsing nephrotic syndrome (FRNS) and steroid-dependent nephrotic syndrome (SDNS). We investigated the efficacy and safety of rituximab in patients with high disease activity. We did a multicentre, double-blind, randomised, placebo-controlled trial at nine centres in Japan. We screened patients aged 2 years or older experiencing a relapse of FRNS or SDNS, which had originally been diagnosed as nephrotic syndrome when aged 1-18 years. Patients with complicated FRNS or SDNS who met all other criteria were eligible for inclusion after remission of the relapse at screening. We used a computer-generated sequence to randomly assign patients (1:1) to receive rituximab (375 mg/m(2)) or placebo once weekly for 4 weeks, with age, institution, treatment history, and the intervals between the previous three relapses as adjustment factors. Patients, guardians, caregivers, physicians, and individuals assessing outcomes were masked to assignments. All patients received standard steroid treatment for the relapse at screening and stopped taking immunosuppressive agents by 169 days after randomisation. Patients were followed up for 1 year. The primary endpoint was the relapse-free period. Safety endpoints were frequency and severity of adverse events. Patients who received their assigned intervention were included in analyses. This trial is registered with the University Hospital Medical Information Network clinical trials registry, number UMIN000001405. Patients were centrally registered between Nov 13, 2008, and May 19, 2010. Of 52 patients who underwent randomisation, 48 received the assigned intervention (24 were given rituximab and 24 placebo). The median relapse-free period was significantly longer in the rituximab group (267 days, 95% CI 223-374) than in the placebo group (101 days, 70-155; hazard ratio: 0·27, 0·14-0·53; p<0·0001).

Full Text Available En los últimos años se han identificado muchos síndromes nefróticos familiares y esporádicos que no responden a los tratamientos habituales (esteroides e inmunosupresores, evolucionan con relativa rapidez a la insuficiencia renal crónica y se producen por mutaciones genéticas. La mayoría de los síndromes nefróticos que se trasmiten genéticamente y que pueden ser congénitos, presentarse en el primer año de la vida, o en el niño mayor, son atribuidos a mutaciones en los genes NPHS1, NPHS2, WT1 y LAMB2. Otros síndromes nefróticos producidos por mutaciones genéticas pueden no manifestarse hasta la adultez. El objetivo fundamental de esta revisión fue llamar la atención sobre los síndromes nefróticos producidos por mutaciones genéticas en los que no sólo no se obtienen resultados con los tratamientos inmunosupresores, si no en los que dichos tratamientos pueden ser perjudiciales para el paciente.In past years many familial and sporadic nephrotic syndromes refractory to usual treatments (steroids and immunosuppressives, evolve quickly to a chronic renal failure produced by genetic mutations. Most of nephrotic syndromes genetically transmitted and that may be congenital, present in the first year of life or in the older child, are attributable to NPHS1, NPHS2, WT1 and KLAMB2 gen mutations. Other nephrotic syndromes produced by genetic mutations may not appear until adulthood. The main objective of present review was to alert on the nephrotic syndromes produced by genetic mutations without response to immunosuppressive treatments, but on those in which such treatment may be dangerous for patient.

Full Text Available Giant cell arteritis (GCA is rare in children. The kidneys are generally spared. We present a case of GCA in a 12-year-old girl with severe headache and tender scalp especially over the right temporal area. The right superficial temporal artery was cord like and nodular and the pulsations were barely felt. Several small tender nodular swellings were felt in the occipital area. She had been previously diagnosed as a case of nephrotic syndrome due to underlying membranoproliferative glomerulonephritis. This report is aimed at drawing attention to this rare form of vasculitis in children aiming at decreasing its morbidities.

Full Text Available Nephrotic syndrome in infancy and childhood is known to be associated with a hypercoagulable state and thromboembolic complications, but cerebral sinovenous thrombosis (CST is a very rare and serious one, with only a few isolated reports in the literature. A case is presented of a 9-year-old boy with nephrotic syndrome that acutely developed signs and symptoms of intracranial hypertension syndrome. CST was diagnosed on cranial CT and MRI and he gradually recovered after treatment with anticoagulants. The diagnosis of CST should be considered in any patient with nephrotic syndrome who develops neurologic symptoms. The discussion of this case, coupled with a review of the literature, emphasizes that early diagnosis is essential for institution of anticoagulation therapy and a successful outcome. This report also illustrates the difficulties that may be encountered in managing such a patient.

Available data on plasma homocysteine level in patients with nephrotic syndrome (NS) are controversial with increased, decreased and unchanged values reported. Therefore, plasma homocysteine and serum B vitamins in Nigerian children with NS were assessed in this study. Fasting blood samples were analysed for plasma homocysteine, serum folate and B vitamins in 42 children with NS and 42 age and sex-matched healthy controls in this case control study. Data were compared between NS and control using t test and Chi square. Relationships were tested with regression analysis with p set at 0.05. Prevalence of hyperhomocysteinaemia, low folate and cyanocobalamin in NS was 57.1%, 14.3% and 9.5% respectively. The mean homocysteine level was significantly higher in NS than control (11.3±2.6 µmol/L versus 5.5±2.3 µmol/L). Also, NS had lower folate and cyanocobalamin than control: 9.1±3.9 ng/mL versus 11.2±3.1 ng/dL and 268.5±95.7 pg/mL versus 316±117.2 pg/mL respectively. Weak but significant correlation between homocysteine and serum albumin (r = 0.347), folate (r = -0.607) and vitamin B12 (r = -0.185) were found in the NS group. Significant relationship was also found between homocysteine and vitamin B12 (ß = -0.64, 95% CI = -1.20, -0.08) after controlling for folate and vitamin B6 levels. Clinically important hyperhomocysteinaemia and low B vitamins occur in Nigerian children with nephrotic syndrome. This data suggest that potential usefulness of folate and vitamin B supplementation for reducing high homocysteine levels in nephrotic syndrome need to be further investigated.

We investigated the value of genetic, histopathologic, and early treatment response information in prognosing long-term renal outcome in children with primary steroid-resistant nephrotic syndrome. From the PodoNet Registry, we obtained longitudinal clinical information for 1354 patients (disease onset at >3 months and children, respectively, with the highest remission rates achieved with calcineurin inhibitor-based protocols. Ten-year ESRD-free survival rates were 43%, 94%, and 72% in children with IIS resistance, complete remission, and partial remission, respectively; 27% in children with a genetic diagnosis; and 79% and 52% in children with histopathologic findings of minimal change glomerulopathy and FSGS, respectively. Five-year ESRD-free survival rate was 21% for diffuse mesangial sclerosis. IIS responsiveness, presence of a genetic diagnosis, and FSGS or diffuse mesangial sclerosis on initial biopsy as well as age, serum albumin concentration, and CKD stage at onset affected ESRD risk. Our findings suggest that responsiveness to initial IIS and detection of a hereditary podocytopathy are prognostic indicators of favorable and poor long-term outcome, respectively, in children with steroid-resistant nephrotic syndrome. Children with multidrug-resistant sporadic disease show better renal survival than those with genetic disease. Furthermore, histopathologic findings may retain prognostic relevance when a genetic diagnosis is established. Copyright © 2017 by the American Society of Nephrology.

Full Text Available Disturbed kidney function is a common complication after bone marrow transplantation. Recently, attention has been given to immune-mediated glomerular damage related to graft versus host disease (GVHD. We describe a 19-year-old woman who developed membranous glomerulonephritis after bone marrow transplantation (BMT. Six months later, she developed soft palate, skin and liver lesions considered to be chronic GVHD. Fifteen months after undergoing BMT, this patient presented with nephrotic syndrome. A renal biopsy showed mem-branous glomerulonephritis associated with a focal segmental glomerulosclerosis. She was started on corticosteroid treatment with good outcome.

We investigated the distribution of nephrin by immunofluorescence microscopy in renal biopsies of patients with nephrotic syndrome: 13 with membranous glomerulonephritis (GN), 10 with minimal change GN, and seven with focal segmental glomerulosclerosis. As control, six patients with IgA GN without nephrotic syndrome and 10 normal controls were studied. We found an extensive loss of staining for nephrin and a shift from a podocyte-staining pattern to a granular pattern in patients with nephrotic syndrome, irrespective of the primary disease. In membranous GN, nephrin was co-localized with IgG immune deposits. In the attempt to explain these results, we investigated in vitro whether stimuli acting on the cell cytoskeleton, known to be involved in the pathogenesis of GN, may induce redistribution of nephrin on the surface of human cultured podocytes. Aggregated but not disaggregated human IgG(4), plasmalemmal insertion of membrane attack complex of complement, tumor necrosis factor-alpha, and puromycin, induced the shedding of nephrin with a loss of surface expression. This phenomenon was abrogated by cytochalasin and sodium azide. These results suggest that the activation of cell cytoskeleton may modify surface expression of nephrin allowing a dislocation from plasma membrane to an extracellular site.

Rituximab is effective against complicated childhood steroid-dependent nephrotic syndrome (SDNS). Peripheral blood B-lymphocyte (B-cell) depletion is strongly correlated with persistent remission, relapse rarely occurring during B-cell depletion; however, we have encountered several such patients. We retrospectively analyzed the characteristics and clinical course of 82 patients with SDNS treated with rituximab from January 2007 to December 2012 in our institution. Six of 82 patients (7.3%) had relapses during B-cell depletion after receiving rituximab (relapsed group). The remaining 76 patients did not have relapses during B-cell depletion (non-relapsed group). The median time to initial relapse during B-cell depletion was 85 days after receiving rituximab, which is significantly shorter than in the non-relapsed group (410 days, p = 0.0003). The median annual numbers of relapses after receiving rituximab were 2.5 and 0.9 in the relapsed and non-relapsed groups, respectively (p depletion did not differ between the two groups. Relapse during B-cell depletion after receiving rituximab suggests that various pathophysiological mechanisms play a part in childhood nephrotic syndrome.

Full Text Available Introduction. Congenital nephrotic syndrome (CNF is manifested at birth or within the first three months of life. The Finnish-type of CNF is caused by the mutation of the NPHS1 gene, which encodes nephrin in the podocyte slit diaphragm. It is a very severe disease, for which immunosuppressive therapy is not advised. Here we describe a patient with CNF who responded to CsA by partial remission. Case outline. A girl aged 2.5 months presented with severe non-syndromic steroid-resistant nephrotic syndrome. She needed aggressive support including daily albumin infusions and diuretics. Substitution of vitamin D, thyroxin, and anticoagulants were regularly administered. She was also treated with angiotensin converting enzyme inhibitor, without clear benefits regarding proteinuria. In addition, she received intravenous gamma-globulin replacement therapy and antibiotics during frequent infections. While waiting for the results of genetic analyses and faced with many problems related to daily albumin infusions, infections, and thromboembolic complications, cyclosporine A (CsA was introduced as an alternative to early nephrectomy and consequent renal failure. The patient responded by partial remission and CsA treatment continued at home without the albumin infusions. After almost five years since the beginning of the treatment, the patient’s renal function remains unreduced. Conclusion. Our case demonstrates that CsA can induce partial remission in patients with genetic forms of steroid-resistant nephrotic syndrome without influencing the glomerular filtration rate. However, its long-term effect and safety should carefully be monitored. [Project of the Ministry of Education, Science and Technological Development of Republic of Serbia, Grant No. 175079

Renal amyloidosis is one of the most severe complications of familial Mediterranean fever (FMF). Colchicine has reduced the incidence of this complication, which now only appears in untreated, under-treated and resistant patients, but it is usually ineffective in patients with advanced amyloidosis. Here we report a patient with FMF and biopsy-proven amyloidosis who presented with nephrotic syndrome despite colchicine treatment. Anakinra (an interleukin-1β inhibitor) was started and a dramatic complete remission of nephrotic syndrome was observed in the following months. Anakinra can be an effective treatment for FMF patients with severe secondary amyloidosis. Copyright © 2015 Sociedad Española de Nefrología. Published by Elsevier España, S.L.U. All rights reserved.

Full Text Available Childhood nephrotic syndrome is a chronic disease harmful to growth of children. Scientific and accurate prediction of negative conversion days for children with nephrotic syndrome offers potential benefits for treatment of patients and helps achieve better cure effect. In this study, the improved backpropagation neural network with momentum is used for prediction. Momentum speeds up convergence and maintains the generalization performance of the neural network, and therefore overcomes weaknesses of the standard backpropagation algorithm. The three-tier network structure is constructed. Eight indicators including age, lgG, lgA and lgM, etc. are selected for network inputs. The scientific computing software of MATLAB and its neural network tools are used to create model and predict. The training sample of twenty-eight cases is used to train the neural network. The test sample of six typical cases belonging to six different age groups respectively is used to test the predictive model. The low mean absolute error of predictive results is achieved at 0.83. The experimental results of the small-size sample show that the proposed approach is to some degree applicable for the prediction of negative conversion days of childhood nephrotic syndrome.

Full Text Available Nephrotic syndrome (NS is an autoimmune disease that correlates to the imbalance of regulatory T cells (TReg. This study was aimed to investigate the effect of vitamin D as adjuvant therapy of TReg population in pediatric nephrotic syndrome. This study was designed randomized clinical trial, double blind, with pre- and post-test control groups involving 15 subjects newly diagnosed with NS. Subjects were divided into 2 groups, namely K1 for group treated with prednisone+vitamin D and K2 group for prednisone treatment only. The population of TReg in peripheral blood mononuclear cells (PBMC was analyzed using flowcytometry. Vitamin D serum level was measured through ELISA method. Results showed that there was a significant elevation of TReg (independent t-test, p = 0.010 in K1 group, which was higher than in K2 group. The Pearson test in the K1 group showed that vitamin D level was positively correlated with TReg (p = 0.039, r = 0.779.

A Novel Biomarker Panel to Identify Steroid Resistance in Childhood Idiopathic Nephrotic Syndrome

Full Text Available Idiopathic nephrotic syndrome (NS is the most common glomerular disorder of childhood. Response to initial treatment with corticosteroids is an indicator of prognosis, as resistant patients often present more progressive disease. In this cross-sectional pilot study, we set out to discover a panel of noninvasive biomarkers that could distinguish steroid-resistant nephrotic syndrome (SRNS from steroid-sensitive nephrotic syndrome (SSNS. Information gleaned from such a panel could yield more individualized treatment plans and prevent unnecessary steroid exposure in patients unlikely to respond. Urine was collected from 50 pediatric patients diagnosed with idiopathic NS at Cincinnati Children’s Hospital Medical Center. Isobaric tags for relative and absolute quantitation (iTRAQ was used to discover 13 proteins that were differentially expressed in SSNS vs SRNS in a small 5 × 5 discovery cohort. Suitable assays were found for 9 of the 13 markers identified by iTRAQ and were used in a 25 SRNS × 25 SSNS validation cohort. Vitamin D–binding protein (VDBP, alpha-1 acid glycoprotein 1 (AGP1, alpha-1 acid glycoprotein 2 (AGP2, alpha-1-B glycoprotein (A1BG, fetuin-A, prealbumin, thyroxine-binding globulin and hemopexin, and alpha-2 macroglobulin were measured and combined with urine neutrophil gelatinase–associated lipocalin (NGAL, which had been previously shown to distinguish patients with SRNS. Urinary VDBP, prealbumin, NGAL, fetuin-A, and AGP2 were found to be significantly elevated in SRNS using univariate analysis, with area under the receiver operating characteristic curves (AUCs ranging from 0.65 to 0.81. Multivariate analysis revealed a panel of all 10 markers that yielded an AUC of 0.92 for identification of SRNS. A subset of 5 markers (including VDBP, NGAL, fetuin-A, prealbumin, and AGP2 showed significant associations with SRNS and yielded an AUC of 0.85.

Objective: To explore the clinical significance of changes of plasma leptin and serum IL-6, IL-18 levels after treatment in patients with children nephrotic syndrome. Methods: Plasma leptin (with RIA) serum IL-6, IL-18 (with ELISA) levels were measured in 31 patients with children nephrotic syndrome both before and after treatment as well as in 30 controls. Results: Before treatment,the plasma leptin and serum IL-6, IL-18 levels were significantly higher than those in controls(P <0.01). After treatment for 3 months, the levels in patients though dropped markedly remained significantly higher than those in controls (P<0.05). Plasma leptin levels were positively correlated with IL-6, IL-18 levels (r=0.6138, 0.5784, P<0.01). Conclusion: Changes of plasma leptin and serum IL-6, IL-18 levels after treatment might be of prognostic importance in patients with children nephrotic syndrome. (authors)

Adult-onset nephrotic syndrome (NS) differs from its pediatric counterpart in several important ways. Most importantly, NS in adults is more etiologically heterogeneous compared to children, and thus treatment approaches rely heavily on the histological diagnosis provided by renal biopsy. The evidence-based approach to treatment of adult NS has been critically examined by the Kidney Disease Improving Global Outcomes (KDIGO) guidelines in glomerulonephritis, published in 2012. Here, we examine the strengths and limits of those guidelines and review recent work that expands the evidence-based approach.

The Stewart model for analyzing acid-base disturbances emphasizes serum albumin levels, which are ignored in the traditional Boston model. We compared data derived using the Stewart model to those using the Boston model in patients with nephrotic syndrome. Twenty-nine patients with nephrotic syndrome and six patients without urinary protein or acid-base disturbances provided blood and urine samples for analysis that included routine biochemical and arterial blood gas tests, plasma renin activity, and aldosterone. The total concentration of non-volatile weak acids (A TOT ), apparent strong ion difference (SIDa), effective strong ion difference (SIDe), and strong ion gap (SIG) were calculated according to the formulas of Agrafiotis in the Stewart model. According to the Boston model, 25 of 29 patients (90%) had alkalemia. Eighteen patients had respiratory alkalosis, 11 had metabolic alkalosis, and 4 had both conditions. Only three patients had hyperreninemic hyperaldosteronism. The Stewart model demonstrated respiratory alkalosis based on decreased PaCO 2 , metabolic alkalosis based on decreased A TOT , and metabolic acidosis based on decreased SIDa. We could diagnose metabolic alkalosis or acidosis with a normal anion gap after comparing delta A TOT [(14.09 - measured A TOT ) or (11.77 - 2.64 × Alb (g/dL))] and delta SIDa [(42.7 - measured SIDa) or (42.7 - (Na + K - Cl)]). We could also identify metabolic acidosis with an increased anion gap using SIG > 7.0 (SIG = 0.9463 × corrected anion gap-8.1956). Patients with nephrotic syndrome had primary respiratory alkalosis, decreased A TOT due to hypoalbuminemia (power to metabolic alkalosis), and decreased levels of SIDa (power to metabolic acidosis). We could detect metabolic acidosis with an increased anion gap by calculating SIG. The Stewart model in combination with the Boston model facilitates the analysis of complex acid-base disturbances in nephrotic syndrome.

Full Text Available A 36-year-old previously healthy male presented with subacute onset of shortness of breath and chest pain. He was diagnosed with bilateral extensive pulmonary embolism (PE. In the absence of any predisposing factors, an extensive workup for unprovoked thrombophilia was done. During the course of his illness, the patient developed anasarca and was diagnosed to be suffering from nephrotic syndrome (NS, secondary to membranous glomerulopathy. Although, thrombotic complications are commonly associated with NS, it is unusual for PE to be the primary presenting feature in these patients.

Full Text Available Marfan syndrome (MFS, the founding member of connective tissue disorder, is an autosomal dominant disease; it is caused by a deficiency of the microfibrillar protein fibrillin-1 (FBN1 and characterized by involvement of three main systems; skeletal, ocular, and cardiovascular. More than one thousand mutations in FBN1 gene on chromosome 15 were found to cause MFS. Nephrotic syndrome (NS had been described in very few patients with MFS being attributed to membranoproliferative glomerulonephritis secondary to infective endocarditis. Focal segmental glomerulosclerosis (FSGS had been reported in NS in conjunction with MFS without confirming the diagnosis by mutational analysis of FBN1. We hereby present an Egyptian family with MFS documented at the molecular level; it showed a male proband with NS secondary to FSGS, unfortunately, we failed to make any causal link between FBN dysfunction and FSGS. In this context, we review the spectrum of renal involvements occurring in MFS patients.

Full Text Available Steroid-resistant nephrotic syndrome (SRNS patients are candidates for other alter-native drug regimes, and the non-responsiveness to steroid is more common among glomerulo-nephritides other than minimal change disease. Without performing biopsy and proper renal histology, progression of the disease cannot be assessed. Fractional excretion of magnesium (FE Mg has been found to correlate directly with various renal histologies. The aim of this study is to evaluate the relationship of FE Mg in children with the histological pattern in SRNS. In this prospective observational study, 40 children of nephrotic syndrome, both with the first episode as well as relapse, aged 1-12 years were included in the study. Of them, 20 were steroid-responsive cases and 20 were steroid-resistant cases. FE Mg was determined in all the patients and renal histology was performed in the steroid-resistant cases. A correlation was found between FE Mg and renal histology. Data were analyzed in SPSS program version-16. Comparison of two groups was performed by the Fisher exact test and unpaired t test. P-value less than 0.05 were considered to be significant. The results of histo-pathology showed that the mean difference in FE Mg was significant (P <0.001, as FE Mg was 7.0 ± 2.3% in mesangiocapillary glomerulonephritis, 6.9 ± 1.3% in focal segmental glomerulosclerosis, 4.7 ± 0.6% in immunoglobulin M nephropathy, 4.5 ± 1.2% in focal segmental proliferative glomerulo-nephritis, 4.4 ± 1.6% in minimal change disease, 4.2 ± 0.4% in diffuse mesangial proliferative glome-rulonephritis and 3.8 ± 1.3% in mesangial proliferative glomerulonephritis. There was a statistically significant difference between FE Mg in steroid-resistant nephrotic syndrome (4.9 ± 1.9 and steroid-responsive syndrome (1.2 ± 0.3. FE Mg is a simple, minimally invasive screening marker for SRNS, and is an early predictor of clinical outcome. It can be considered as an initial investigation where biopsy

Clinical observations suggest that treatment of Rituximab might be less effective in patients with nephrotic range proteinuria when compared to nonnephrotic patients. It is conceivable that the reason for this is that significant amounts of Rituximab might be lost in the urine in a nephrotic patient and that these patients require a repeated or higher dosage. However, this has not been systematically studied. In this case report we describe two different patients with nephrotic range proteinuria receiving Rituximab. The first patient received Rituximab for therapy resistant cryoglobulinemic membranoproliferative glomerulonephritis and the other for second line treatment of Felty's syndrome. We employed flow cytometry to determine the amount of Rituximab excretion in both urine and peritoneal fluid specimens in these patients following administration of Rituximab. We found that a significant amount of Rituximab is lost from the circulation by excretion into the urine. Furthermore we saw a close correlation of the excretion of Rituximab to the excretion of IgG molecules suggesting selectivity of proteinuria as the determining factor of Rituximab excretion. Further larger scale clinical studies could have the potential to evaluate an optimal cut-off value of IgG urinary loss before a possible administration of Rituximab therefore contributing to a more individualized treatment approach in patients with nonselective and nephrotic range proteinuria.

Management of Diabetes Associated with Nephrotic Syndrome: Therapeutic Potential of Dapagliflozin for Protracted Volume Retention

2015-01-01

Full Text Available A 48-year-old female was admitted to our hospital presenting with a chief complaint of progressive swelling because of diabetic nephrotic syndrome. Dapagliflozin seemed to play a role in accelerating the patient's urinary sodium excretion as well as reducing gross fluid retention despite the fact that her nephrotic condition was resistant to furosemide. Our experience emphasizes a potential novel approach to overcoming loop diuretic resistance using this agent among some subsets of type 2 diabetic subjects complicated with severe volume accumulation. We believe that combination treatment consisting of dapagliflozin and furosemide may produce diuretic synergy via sequential nephron blockade. The accumulation of more experience with additional cases similar to ours requires continuous and careful attention.

Full Text Available Aims. To explore whether Astragalus or its formulations could prevent upper respiratory infection in children with nephrotic syndrome and how best to use it. Methods. We transformed a common clinical question in practice to an answerable question according to the PICO principle. Databases, including the Cochrane Library (Issue 5, 2012, PUBMED (1966–2012.8, CBM (1978–2012.8, VIP (1989–2012.8, and CNKI (1979–2012.8, were searched to identify Cochrane systematic reviews and clinical trials. Then, the quality of and recommendations from the clinical evidence were evaluated using the GRADEpro software. Results. The search yielded 537 papers. Only two studies with high validity were included for synthesis calculations. The results showed that Astragalus granules could effectively reduce URTI in children with nephrotic syndrome compared with prednisone treatment alone (23.9% versus 42.9%; RR = 0.56 and 95% CI = 0.33–0.93. The dose of Astragalus granules was 2.25 gram (equivalent to 15 gram crude Astragalus twice per day, at least for 3–6 months. The level of evidence quality was low, but we still recommended the evidence to the patient according to GRADEpro with the opinion of the expert. Followup showed the incidence of URTI in this child decreased significantly. Conclusions. Astragalus granules may reduce the incidence of URTI in children with nephrotic syndrome.

Full Text Available Background/Aims: LDL apheresis (LDL-A is used for drug-resistant nephrotic syndrome (NS as an alternative therapy to induce remission by improvement of hyperlipidemia. Several clinical studies have suggested the efficacy of LDL-A for refractory NS, but the level of evidence remains insufficient. A multicenter prospective study, POLARIS (Prospective Observational Survey on the Long-Term Effects of LDL Apheresis on Drug-Resistant Nephrotic Syndrome, was conducted to evaluate its clinical efficacy with high-level evidence. Methods: Patients with NS who showed resistance to primary medication for at least 4 weeks were prospectively recruited to the study and treated with LDL-A. The long-term outcome was evaluated based on the rate of remission of NS 2 years after treatment. Factors affecting the outcome were also examined. Results: A total of 58 refractory NS patients from 40 facilities were recruited and enrolled as subjects of the POLARIS study. Of the 44 subjects followed for 2 years, 21 (47.7% showed remission of NS based on a urinary protein (UP level Conclusions: Almost half of the cases of drug-resistant NS showed remission 2 years after LDL-A. Improvement of nephrotic parameters at termination of the LDL-A treatment was a predictor of a favorable outcome.

Levamisole in steroid-sensitive nephrotic syndrome of childhood: the lost paradise?

Among the different drugs used for sparing steroids in steroid-sensitive nephrotic syndrome (SSNS) with frequent relapses and steroid dependency, levamisole is the least toxic and the least expensive. However, it is neither approved for this indication nor widely used in Europe. This may be explained by the difficulty in obtaining levamisole in some countries and the lack of good quality evidence for its effectiveness. Evidence is limited to three clinical trials that all suffered from methodological limitations. Statistical synthesis of these trials showed that levamisole reduces the risk of a relapse during treatment (relative risk 0.60, 95% confidence interval 0.45-0.79). From the available information, no conclusions can be drawn on the steroid-sparing effect, the long-term efficacy, and safety, as well as possible differences in efficacy in different subgroups of SSNS patients. The confirmation of a favorable effect of levamisole on the reduction of the frequency of relapses and on sparing steroids in an adequately powered, double-blind, placebo-controlled, randomized, multi-center clinical trial will promote consensus on the place of levamisole in the treatment of SSNS of childhood. Follow-up should be at least 1 year to evaluate long-term efficacy and side effects. If the results of such a clinical trial confirm the beneficial effects of levamisole in nephrotic syndrome, this may allow registration for this indication and interest companies other than Jansen-Cilag, which only recently has decided to stop its production.

Full Text Available Nephrotic syndrome (NS is characterized by nephritic-range proteinuria and the triad of clinical findings associated with large urinary losses of protein, hypoalbuminemia, edema and hyperlipidemia. More than 80% of children below 13 years of age with primary NS have steroid-responsive forms. There is no identifiable cause of attention-deficit hyperactivity disorder (ADHD. It is likely that the symptoms of ADHD represent a final common pathway of diverse causes, including genetic, organic and environmental etiologies. This case-control study was performed on 130 children aged between 5 and 13 years who were followed-up for two years. Sixty-five children with steroid-dependent nephrotic syndrome (SDNS as the case group and 65 healthy children as the control group were included in the study. Patients with minimal change NS were treated with prednisolone for at least six months. Conner′s Parent Rating Scale - 48 (CPRS-48 was completed by the parents and the children were identified with any form of ADHD. Then, children were referred to an expert psychiatrist. The collected data were analyzed with SPSS software. The result showed that there was no significant relationship between different types of ADHD in both groups. Thus, based on current study, one may conclude that there are no significant differences between prevalence of ADHD in children with SDNS and the control group.

Light chain deposition disease (LCDD) is a monoclonal immunoglobulin deposition disease (MIDD) that is characterized by the deposition of monoclonal light chains in multiple organs, including the kidney. It is a rare disorder caused by an underlying monoclonal plasma cell dyscrasia. LCDD with renal involvement causes proteinuria, which sometimes can lead to nephrotic syndrome. The monoclonal light chains are mostly in the κ form. Treatment of LCDD is the same as that for multiple myeloma (MM); however, some conventional anticancer drugs show substantial toxicity and therefore cannot be administered to older patients or those with renal impairment. An 80-year-old woman was referred to our department with severe nephrotic syndrome (13.6 g/gCr) and anemia. A renal biopsy showed mesangial proliferation and mesangial matrix expansion, and immunohistochemistry showed positive staining for λ chains along the glomerular basement membrane, but was negative for κ chains or amyloid deposition. A bone marrow biopsy revealed 64% plasma cells. Immunoglobulin G (IgG)-λ type M protein was detected, and the levels of free λ chain was significantly increased. We concluded that her nephrotic syndrome was caused by LCDD, which resulted from IgG-λ MM. The induction of a BCD (bortezomib, cyclophosphamide, and dexamethasone) treatment regimen did not lead to a hematological response or decrease in proteinuria. The administration of combination therapy of lenalidomide and prednisolone led to the successful reduction of proteinuria and hematuria. We presented a very rare case report describing the successful treatment of LCDD (λ chain)-induced nephrotic syndrome with lenalidomide.

Full Text Available The management of idiopathic nephrotic syndrome (INS in children includes immunosuppressive and symptomatic treatment. The response to corticosteroid therapy is the best prognostic marker of the disease. The majority of children with INS (about 85% are steroid-sensitive as they normalize proteinuria within 4 weeks of daily, oral prednisone administration. The most of steroid-sensitive patients (94% has minimal change of nephrotic syndrome, while the majority (80.5%-94.4% of those who are steroid-resistant has focal segmental glomerulosderosis or mesangioproliferative glomerulonephritis. Initial therapy of INS consists of 60 mg/m2/day prednisone daily for 4 weeks followed by 40 mg/m2 on alternate days for 4 weeks, thereafter decreasing alternate day therapy every month by 25% over the next 4 months. Thus, the overall duration of the initial cortico-steroids course is 6 months that may be significantly protective against the future development of frequent relapses. Approximately 30% of patients experience only one attack and are cured after the first course of therapy; 10-20% have only 3 or 4 steroid-responsive episodes before permanent cure; the remaining 40-50% of patients are frequent relapsers, or steroid-dependent. Standard relapse therapy consists of 60 mg/m2/ day prednisone until urine is protein free for at least 3 days, followed by 40 mg/m2 on alternate days for 4 weeks. The treatment of frequent-relapses and steroid-dependent INS includes several different regimens: maintenance (6 months alternate steroid therapy just above steroid threshold (0.1-0.5 mg/kg/ 48h, levamisole, alkylating agents (cyclophosphamide or chlorambucil or cyclosporine. The worse prognosis is expected in steroid-resistant patients who are the most difficult to treat. Renal biopsy should be performed in them. At present, there is no consensus on therapeutic regimen for steroid-resistant patients. The following immunosuppressive drugs have been used with varying

Childhood Idiopathic Steroid Resistant Nephrotic Syndrome, Different Drugs and Outcome

Background: The management of steroid resistant nephrotic syndrome (SRNS) is quite difficult in paediatric patients. Not only the remission is difficult but also these patients are at risk of progression to end stage renal disease (ESRD). The goal of treatment is either to achieve complete remission or even partial remission as it is the most important predictor of disease outcome. Methods: This study was conducted at The Children Hospital, Lahore from February 2014 to May 2015. The SRNS patients of either sex between ages of 1-12 years were included with histology showing mesangioproliferative glomerulonephritis (MesangioPGN), focal segmental glomerulosclerosis (FSGS) or minimal change disease (MCD). Patients were given different immunosuppressant drugs and steroid 30 mg/m/sup 2/ alternate day therapy on case to case basis and kept on regular follow up to check for response and adverse effects. Results: Total of 105 patients included, 63 (60 percent) male and 42 (40 percent) female patients. The age ranges from 1.08 to 12 years, mean age of 6.53 years and SD of ±3.17. Tacrolimus was the most common drug used 43 (41 percent) patients followed by cyclosporine in 38 (36.2 percent) patients, while Mycophenolate mofetil (MMF) was prescribed in 21 (20 percent) patients. Complete response was in 96 (91.4 percent) initially while partial response was seen in 8 (7.6 percent) patients. On follow up, 92 (87.6 percent) patients showed complete response and partial response was in 5 (4.7 percent) patients. Cushingoid features and hypertrichosis were the most common adverse effect seen. Conclusion: Steroid resistant nephrotic syndrome can be managed well with various immunosuppressant drugs and steroids but treatment should be individualized according to clinical presentation, disease histology and cost/social factors.

Diabetes and Nephrotic syndrome (NS) promote plaque-related gingivitis and yeast-like fungal infections. The study assesses the impact of Candida spp. and general disease- or treatment-related factors on plaque-related gingivitis severity in children and adolescents with Nephrotic syndrome /diabetes. Body mass index (BMI), BMI standard deviation score, and oral cavity (Plaque Index--PLI, Gingival Index--GI, mucosa status, presence and Candida enzymatic activity) were assessed in 96 patients (32 with NS: 30- immunosuppressive treatment, 35--type 1 diabetes, and 29 generally healthy), aged; 3-18 years. Laboratory included cholesterol and triglyceride measurements; in diabetic subjects- glycated haemoglobin, in NS: total protein, albumin, creatinine, haemoglobin, haematocrit, white cell count, urinary protein excretion. Medical records supplied information on disease duration and treatment. A statistical analysis was performed; Kendall Tau coefficient, chi-square test, t-test, and multiple regression analysis ( P Gingivitis occurred more frequently in patients with NS/diabetes. Gingivitis severity was correlated with PLI, age, and yeast enzyme activity in NS--to with immunosuppressive treatment with >1 drug, drug doses, treatment duration, lipid disorders, and BMI; in diabetes, with blood glucose and glycated haemoglobin >8%. Poor hygiene control is the main cause of gingivitis. Gingivitis severity is most likely related to age, lipid disorders and increase in body mass. Candida spp., in uncompensated diabetes and in those using immunosuppressive treatment, might intensify plaque-related gingivitis.

Generalised pustular psoriasis, psoriatic arthritis and nephrotic syndrome associated with systemic amyloidosis.

The case report is presented of a psoriatic patient with arthropathy, generalised pustular psoriasis and nephrotic syndrome, in whom systemic amyloidosis developed. The literature reports 13 cases of psoriasis associated with amyloidosis, 3 of whom suffered from pustular psoriasis as does our case. With the addition of our case, 12 of these 14 had concomitant arthropathy. This seems to suggest that arthritis is an important factor in the appearance of amyloidosis. Rectal biopsy and/or renal biopsy may be helpful in establishing the diagnosis of amyloidosis relatively early in patients with psoriatic arthritis.

Oral colonization with Candida spp. is not synonymous with a systemic active infection. The aim of the study was to evaluate enzymatic activity of Candida strains isolated from the oral cavity in patients with nephrotic syndrome (NS) and to compare it with the activity determined in urine. We studied 32 children with NS and 26 control healthy children. Children with NS were treated with glucocorticosteroids, cyclosporin A, mycophenolate mofetil or azathioprine. In all children, API-ZYM enzymatic tests were performed to evaluate hydrolytic enzymes of Candida isolated from the oral cavity and in urine. Candida spp. were isolated from the oral cavity in 11 patients with NS (34.4%), all receiving immunosuppressive treatment. All strains produced valine arylamidase, 9 alpha-glucosidase (E16), and 9 N-acetyl-beta-glucosaminidase (E18). A positive correlation between the presence of Candida in the oral cavity and E16 and E18 enzymatic activity in both oral cavity and urine was found. A dose of cyclosporin A had an effect on the enzymatic activity (p Candida invasion. The results of this study suggest that oral candida infection should be monitored in children with nephrotic syndrome, particularly those treated with immunosuppressive agents.

Full Text Available The nephrotic syndrome (NS has been associated with a variety of malignancies in a number of reports in the literature, but has been reported in only nine cases associated with ovarian neoplasms. Membranous nephropathy is the most common glomerular pathology causing the NS in patients with solid tumors. There has been only one report of an ovarian neoplasm associated with minimal change disease (MCD. We describe the case of a 36-year-old woman who presented with the NS secondary to biopsy-proven MCD, likely secondary to mature ovarian teratoma. Treatment by tumor removal and prednisone led to remission of the NS. To the best of our knowledge, this is the first report of an ovarian teratoma and the second report of an ovarian neoplasm associated with MCD.

Galloway-Mowat syndrome (GAMOS) is an autosomal-recessive disease characterized by the combination of early-onset nephrotic syndrome (SRNS) and microcephaly with brain anomalies. Here we identified recessive mutations in OSGEP, TP53RK, TPRKB, and LAGE3, genes encoding the four subunits of the KEOPS complex, in 37 individuals from 32 families with GAMOS. CRISPR-Cas9 knockout in zebrafish and mice recapitulated the human phenotype of primary microcephaly and resulted in early lethality. Knockdown of OSGEP, TP53RK, or TPRKB inhibited cell proliferation, which human mutations did not rescue. Furthermore, knockdown of these genes impaired protein translation, caused endoplasmic reticulum stress, activated DNA-damage-response signaling, and ultimately induced apoptosis. Knockdown of OSGEP or TP53RK induced defects in the actin cytoskeleton and decreased the migration rate of human podocytes, an established intermediate phenotype of SRNS. We thus identified four new monogenic causes of GAMOS, describe a link between KEOPS function and human disease, and delineate potential pathogenic mechanisms.

Background: Steroid-resistant nephrotic syndrome (SRNS) is a common problem but difficult to treat for pediatric nephrologists. Due to paucity of studies done in few centres in southern Pakistan regarding the histopathological aspects in paediatric patients with SRNS, this study was conducted to determine the histopathological spectrum in children with SRNS at our centre. Method: This descriptive study has been conducted at the Nephrology department, The Children's Hospital Lahore from February 2014 to January 2015. Based upon history, physical examination and laboratory results, all patients diagnosed as idiopathic SRNS were included in the study and renal biopsy was done to determine the underlying pathology. Histopathology reports were retrieved and data analysis done using SPSS-20.0. Results: There were a total of 96 patients, 64 (66.7 percentage) males and 32 (33.3 percentage) females. The age range was from 0.80 to 15 years with mean age of presentation being 6.34+3.75 years. The most common histo-pathological pattern was mesangio-proliferative Glomerulonephritis found in 79 (82.3 percentage) cases followed by Focal segmental glomerulosclerosis (FSGS) in 9 (9.4 percentage) patients while Minimal change disease (MCD) was seen in 5 (5.2 percentage) subjects. Conclusion: Mesangioproliferative glomerulonephritis is the most common histological pattern seen in children presenting with idiopathic SRNS at our centre followed by FSGS and MCD. (author)

Congenital nephrotic syndrome of the Finnish type (CNF) is due to NPHS1 mutation and is responsible for a variety of urinary protein losses. We report the case of a 4-month-old girl with a particularly severe form (proteinuria approximately 150 g/l) of CNF. She developed severe non-regenerative anaemia requiring bi-monthly blood transfusions despite daily EPO (600 UI/kg) and iron supplementation. Epoetin pharmacokinetics revealed a urinary loss of 27% of the given dose within the first 24 h after IV injection. However, plasma levels remained increased after 24 h (228 UI/l). Plasma transferrin and transcobalamin levels were undetectable. Atransferrinaemia and atranscobalaminaemia seem to be responsible for disturbed erythropoiesis.

Myeloproliferative disorders are a rare cause of focal segmental glomerulosclerosis (FSGS), although the mechanism is unclear. Hydroxyurea is commonly used in these disorders for its cytoreductive properties; however, the effect of this treatment on proteinuria or kidney function remains unclear in cases of myeloproliferative disorder-associated FSGS. We describe the clinical course of a patient with polycythemia vera and nephrotic-range proteinuria, demonstrated to have FSGS on biopsy. The patient had a distant history of granulomatosis with polyangiitis (Wegener's), for which he routinely had his kidney function and proteinuria measured, allowing for early detection of nephrotic syndrome soon after being diagnosed with polycythemia vera. Treatment with hydroxyurea resulted in rapid improvement in proteinuria that correlated with a decrease in hematocrit. This response was replicated 2 additional times when the patient was taken off and then restarted on hydroxyurea therapy. He now maintains a steady dose of hydroxyurea with favorable kidney measures (proteinuria with <1g/d of protein excretion and serum creatinine of 1.27mg/dL [corresponding to estimated glomerular filtration rate of 56mL/min/1.73 m(2)]). This case suggests that early screening and treatment for myeloproliferative disorder-associated FSGS may lead to improved long-standing kidney function.

Full Text Available Mutations in the NPHS2 gene, encoding podocin, cause hereditary nephrotic syndrome. The most common podocin mutation, R138Q, is associated with early disease onset and rapid progression to end-stage renal disease. Knock-in mice carrying a R140Q mutation, the mouse analogue of human R138Q, show developmental arrest of podocytes and lethal renal failure at neonatal age. Here we created a conditional podocin knock-in model named NPHS2 R140Q/-, using a tamoxifen-inducible Cre recombinase, which permits to study the effects of the mutation in postnatal life. Within the first week of R140Q hemizygosity induction the animals developed proteinuria, which peaked after 4-5 weeks. Subsequently the animals developed progressive renal failure, with a median survival time of 12 (95% CI: 11-13 weeks. Foot process fusion was observed within one week, progressing to severe and global effacement in the course of the disease. The number of podocytes per glomerulus gradually diminished to 18% compared to healthy controls 12-16 weeks after induction. The fraction of segmentally sclerosed glomeruli was 25%, 85% and 97% at 2, 4 and 8 weeks, respectively. Severe tubulointerstitial fibrosis was present at later disease stage and was correlated quantitatively with the level of proteinuria at early disease stages. While R140Q podocin mRNA expression was elevated, protein abundance was reduced by more than 50% within one week following induction. Whereas miRNA21 expression persistently increased during the first 4 weeks, miRNA-193a expression peaked 2 weeks after induction. In conclusion, the inducible R140Q-podocin mouse model is an auspicious model of the most common genetic cause of human nephrotic syndrome, with a spontaneous disease course strongly reminiscent of the human disorder. This model constitutes a valuable tool to test the efficacy of novel pharmacological interventions aimed to improve podocyte function and viability and attenuate proteinuria

[corrected] Nephrotic syndrome is one of the most frequent glomerular diseases among children, and steroid therapy remains as the treatment choice. In spite of this, 10 to 15% of the patients are steroidresistant, and the best therapy for such cases has never been defined. Mycophenolate acid (MA) is one of the treatments used in such situations. To describe the clinical behavior of children diagnosed with steroid-resistant nephrotic syndrome (SRNS) and to assess the therapeutic response to MA. This was a retrospective and descriptive study. 26 clinical records of patients with SRNS; 70% male and 30% female. All patients underwent kidney biopsies, which showed a predominance of focal segmental glomerulosclerosis (FSGS). The immunosuppresive drugs used were: Mycophenolate mofetil (MMF) 100%, Cyclosporine 69.2%, Cyclophosphamide 23.1%, and Rituximab 23%. One month after treatment initiation with MMF 61.5% achieved remission. The median of relapses per year for the patients was 3 (p25: 2.75 - p75: 4). This median became 1 (p25: 1 - p75: 3.25) after using this medication (p = 0.08). Furthermore, prior to the start of the MMF treatment, the median of the steroid dose was 1 (p25: 0.5- p75: 1.62) mg/k/day. After using MMF, this median became 0.07 (p25: 0 - p75: 0.55) mg/k/day (p < 0.001), in 8 patients prednisolone was stopped. In our experience, treatment with MMF showed positive results such as decrease in the frequency of relapses, less proteinuria, and reduction in the dose of steroids administered without deterioration of glomerular filtration rates. However, more studies are needed to assess efficacy, safety, and optimal dosage.

The management of Steroid Resistant Nephrotic Syndrome (SRNS) is an uphill task for paediatric nephrologists as immunosuppressive agents are the mainstay of treatment in these patients. Tacrolimus is used along with steroids. This study is conducted to see the relationship between the tacrolimus dose, drug level and response in the management of SRNS. Methods: This quasi experimental study was conducted at The Childrens Hospital Lahore over a period of one year. Patients with SRNS of either sex and 1-10 years of age were included and those with secondary nephrotic syndrome were excluded. Tacrolimus was given at a dose of 0.05-0.1 mg/kg/day in 2 divided doses along with steroids. The follow-up was done for six months with proteinuria monitoring and tacrolimus drug levels done two weeks after initiation of treatment. Results: Out of 42 patients, 27 (64.3%) were males and 15 (35.7%) were females. The most common histological diagnosis observed was mesangio-proliferative glomerulonephritis in 30 (71.4%) patients. The tacrolimus trough level range was 0.5-15.20 ng/ml with a mean value of 4.68 ng/ml±2.85. Forty-one (97.6%) children showed complete response to treatment while one patient showed partial response. Conclusion: This study suggests that tacrolimus is an effective drug for treatment of SRNS in paediatric patients and there is no linear relationship between the drug dose, response and drug level.

Full Text Available In Bangladesh, there are very few studies about biopsy proven adult Nephrotic syndrome (NS with histological types and their clinical findings. To determine the histological types of glomerulonephritis (GN in adult NS and correlate them with the clinical presentations and biochemical parameters, we studied 100 biopsies in 87 patients who underwent ultrasonography- guided renal biopsy in Rangpur Medical College and Hospital from July 2010 to June 2012. The mean age of the patients was 32.8 ± 13.2 years; male was preponderance (72.4% and most of the patients (67.8% came from rural areas. Membranoproliferative GN (MPGN was the most common underlying cause that was found in 32 (36.8% patients followed by mesangial prolife- rative GN in 27 (31% patients, membranous GN in 16 (18.4% cases, minimal change disease in four (4.6% patients, diffuse proliferative GN in four (4.6% patients, focal segmental GN, and focal proliferative GN in two (2.4% patients each. High proteinuria level was found in minimal change disease, which was 7.59 ± 0.24 g/24 h (mean ± standard deviation. The most common symptoms were oliguria (92% and edema (86.2% followed by hematuria (dark urine (72.4% and hypertension (35.6%. MPGN was the most common histological type of adult NS in Rangpur.

Full Text Available Nephrotic syndrome (NS is a disease of glomerular filtration barrier failure presenting with variable degrees of proteinuria, hypoalbuminemia, hyperlipidemia, and edema. Inflammation may contribute to the pathogenesis of NS. The aim of this study was to monitor the serum levels of three cytokines [i.e., granulocyte chemotactic protein-2 (GCP-2, growth-related oncogene-α (GRO-α, and interleukin-8 (IL-8] in different stages of NS and to find out whether changes in the levels of these cytokines could be related to the severity of NS. This study included 125 patients who were divided into 40 patients with nephrotic range proteinuria (NRP, 45 patients with NS, and 40 patients who were in remission. This study also included 80 healthy participants as a control group. Enzyme-linked immunosorbent assay was used for the determination of the plasma levels of GRO-α, GCP-2, and IL-8. GCP-2 plasma levels were significantly higher in the NS and NRP groups when compared to the control group, whereas the GRO-α and IL-8 levels were significantly higher in all patient groups in comparison with the control group. All these chemokine levels were significantly decreased in remission as compared with the participants in the NS group (P <0.0001. There was a significant correlation between the cytokine levels and proteinuria and serum albumin in the NS group (P <0.0001. However, in the follow-up group, GCP-2 levels were significantly lower during remission as compared to those with active NS (P <0.0001. Our findings suggest that the pro-inflammatory cytokines GCP-2, GRO-α, and IL-8 could play a role in the pathogenesis of NS, particularly glomerular permeability.

A 74-year-old woman was diagnosed as having transverse colon cancer after diagnosis of nephrotic syndrome caused by membranous nephropathy. Although she had hypoproteinemia and hypoalbuminemia, we judged that she had no major nutritional problem. In previous, similar case reports, the use of human serum albumin and fresh-frozen plasma was suggested to be important to avoid complications in the perioperative period. Thus, we used the same in our patient in the perioperative period. In addition, we paid special attention to perioperative nutrition management and used total parenteral nutrition in perioperative period. We performed laparoscopic assisted right hemicolectomy. On the 15th day after the surgical resection, the patient was discharged without any problems. We considered that postoperative adjuvant chemotherapy with XELOX (CapeOX)should be performed because the TNM pathological stage was pStage III b. Regarding adjuvant chemotherapy for gastrointestinal cancer with nephrotic syndrome, no previous reports detailed the indications for postoperative adjuvant chemotherapy. Upon introduction of adjuvant chemotherapy, we determined adaptation in accordance with the general adaptation criteria. While observing the patient's progress with a nephrologist, we safely completed the scheduled 8 courses adjuvant chemotherapy.

Approximately 20% of children with idiopathic nephrotic syndrome do not respond to steroid therapy. More than 30 genes have been identified as disease-causing genes for the steroid-resistant nephrotic syndrome (SRNS). Few reports were from the Chinese population. The coding regions of genes commonly associated with SRNS were analyzed to characterize the gene mutation spectrum in children with SRNS in central China. The first phase study involved 38 children with five genes (NPHS1, NPHS2, PLCE1, WT1, and TRPC6) by Sanger sequencing. The second phase study involved 33 children with 17 genes by next generation DNA sequencing (NGS. 22 new patients, and 11 patients from first phase study but without positive findings). Overall deleterious or putatively deleterious gene variants were identified in 19 patients (31.7%), including four NPHS1 variants among five patients and three PLCE1 variants among four other patients. Variants in COL4A3, COL4A4, or COL4A5 were found in six patients. Eight novel variants were identified, including two in NPHS1, two in PLCE1, one in NPHS2, LAMB2, COL4A3, and COL4A4, respectively. 55.6% of the children with variants failed to respond to immunosuppressive agent therapy, while the resistance rate in children without variants was 44.4%. Our results show that screening for deleterious variants in some common genes in children clinically suspected with SRNS might be helpful for disease diagnosis as well as prediction of treatment efficacy and prognosis.

Traditional Chinese Medicine for Refractory Nephrotic Syndrome: Strategies and Promising Treatments

Science.gov (United States)

Tu, Yuan-Chao

2018-01-01

Refractory nephrotic syndrome (RNS) is an immune-related kidney disease with poor clinical outcomes. Standard treatments include corticosteroids as the initial therapy and other immunosuppressants as second-line options. A substantial proportion of patients with RNS are resistant to or dependent on immunosuppressive drugs and often experience unremitting edema and proteinuria, cycles of remission and relapse, and/or serious adverse events due to long-term immunosuppression. Traditional Chinese medicine has a long history of treating complicated kidney diseases and holds great potential for providing effective treatments for RNS. This review describes the Chinese medical theories relating to the pathogenesis of RNS and discusses the strategies and treatment options using Chinese herbal medicine. Available preclinical and clinical evidence strongly supports the integration of traditional Chinese medicine and Western medicine for improving the outcome of RNS. Herbal medicine such as Astragalus membranaceus, Stephania tetrandra S. Moore, and Tripterygium wilfordii Hook F can serve as the alternative therapy when patients fail to respond to immunosuppression or as the complementary therapy to improve therapeutic efficacy and reduce side effects of immunosuppressive agents. Wuzhi capsules (Schisandra sphenanthera extract) with tacrolimus and tetrandrine with corticosteroids are two herb-drug combinations that have shown great promise and warrant further studies.

The goal of this study is to identify systematic biomarker panel for primary nephrotic syndromes from urine samples by applying a non-target metabolite profiling, and to validate their utility in independent sampling and analysis by multiplex statistical approaches. Nephrotic syndrome (NS) is a nonspecific kidney disorder, which is mostly represented by minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), and membranous glomerulonephritis (MGN). Since urine metabolites may mirror disease-specific functional perturbations in kidney injury, we examined urine samples for distinctive metabolic changes to identify biomarkers for clinical applications. We developed unbiased multi-component covarianced models from a discovery set with 48 samples (12 healthy controls, 12 MCD, 12 FSGS, and 12 MGN). To extensively validate their diagnostic potential, new batch from 54 patients with primary NS were independently examined a year after. In the independent validation set, the model including citric acid, pyruvic acid, fructose, ethanolamine, and cysteine effectively discriminated each NS using receiver operating characteristic (ROC) analysis except MCD-MGN comparison; nonetheless an additional metabolite multi-composite greatly improved the discrimination power between MCD and MGN. Finally, we proposed the re-constructed metabolic network distinctively dysregulated by the different NSs that may deepen comprehensive understanding of the disease mechanistic, and help the enhanced identification of NS and therapeutic plans for future.

Full Text Available Cyclosporine A (CyA is an effective agent for the treatment of glucocorticoid-dependent idiopathic nephrotic syndrome (GCDNS, but costs are prohibitive in resource-poor societies. The objectives of this study were to evaluate the efficacy and safety of reducing the dose of CyA by co-administering ketoconazole. A prospective study targeting children 2-18 years of age with GCDNS in remission with CyA monotherapy was conducted. CyA dose was reduced by 50% and ketoconazole was added at 25% of the recommended therapeutic dose, and the drug levels and therapeutic and adverse effects (AE were monitored. Continued combined therapy after completion of the 4-week trial period was offered. Ten patients (median age 9.5 years, range 3.0-16.0 years were enrolled in the study. At week 4, the CyA dose was 2.2 ± 0.7 mg/kg/day compared with 5.6 ± 0.9 mg/kg/day at enrolment ( P 50% without increased adverse events or drug monitoring needs. This intervention demonstrates how access of patients with limited resources to needed drugs can be improved by interference with physiological drug elimination.

Nephrotic syndrome (NS) is associated with a significant alteration in protein metabolism. While lowering the concentration of certain proteins, the disease often raises the level of certain other proteins. The current study aimed to investigate the serum erythropoietin (EPO) levels in children with NS either anemic or non-anemic and to compare them to children with iron deficiency anemia (IDA) and healthy controls with normal hemoglobin level (NHB). Sixteen nephrotic children with anemia (NS-A) and 15 nephrotic children with normal hemoglobin level (NS-NHB) were examined and compared with 10 children with iron deficiency anemia (IDA) and 10 healthy controls (NHB). Circulating serum EPO levels, blood indices and iron status were measured in nephrotic patients with anemia (NS-A) and compared to those nephrotic patients with normal HE (NS-NHB). Most NS-A children were steroid resistant. The NS-A children showed greater EPO levels than those without anemia (21.01 ±4.02 mlU/ml versus 9.18 ± 0.79 mlU/ml; P < 0.001) but their response to treatment of anemia was inappropriately low when compared to IDA (EPO 96.9 ±4.9 mlU/ml) despite similar HB concentration. A significant positive correlation was observed between serum EPO and serum albumin in NS-A (r = 0.84, P < 0.001) and in NS-NHB group (r = 0.89, P < 0.001). Moreover, a significant positive correlation was observed between serum EPO and HB in the nephrotic groups indicating a blunted EPO response to anemia in NS-A (r 0.63, P < 0.05) and in NS-NHB group (r = 0.80, P < 0.001). In conclusion, anemia is a common feature of NS and is present even before the worsening of kidney function. Depletion of the iron stores due to loss of iron and transferrin in urine due to massive proteinurea may contribute to the development of anemia, but it was found that iron replacement was ineffective alone

Dynamic hippurate scintigraphy was studied in five pediatric patients. Four had nephrotic syndrome, and of these, three had acute renal failure. The fifth patient had end-stage renal failure. Specific alteration in renal hippurate kinetics offers a noninvasive assessment of renal failure in this clinical setting

2014-12-01

Full Text Available Toxic epidermal necrolysis (TEN is a drug-related fatal disease. Extensive necrosis of the epidermis can lead to serious complications. This report describes two cases of TEN, associated with deflazacort (DFZ, in two boys, aged 4 years and 14 years, with nephrotic syndrome (NS. The 14-year-old male teenager received DFZ following NS relapse. After 17 days, pruritic papules appeared on the lower extremities. Another case involved a 4-year-old boy receiving DFZ and enalapril. After a 41-day DFZ treatment period, erythematous papules appeared on the palms and soles. Within 3 days, both boys developed widespread skin lesions (>50% and were admitted to the intensive care unit for resuscitative and supportive treatment. The patients showed improvement after intravenous immunoglobulin-G therapy. Owing to the rapid, fatal course of TEN, clinicians need to be aware of the adverse effects of this drug when treating cases of NS.

Full Text Available Background. The polymorphism R229Q is one of the most commonly reported podocin sequence variations among steroid-resistant nephrotic syndromes (SRNS. Aim of the Study. We investigated the frequency and risk of this polymorphism among a group of Iraqi children with SRNS and steroid-sensitive nephrotic syndrome (SSNS. Patients and Methods. A prospective case control study which was conducted in Al-Imamein Al-Kadhimein Medical City, spanning the period from the 1st of April 2015 to 30th of November 2015. Study sample consisted of 54 children having NS, divided into 2 groups: patients group consisted of 27 children with SRNS, and control group involved 27 children with SSNS. Both were screened by real time polymerase chain reaction for R229Q in exon 5 of NPHS2 gene. Results. Molecular study showed R229Q polymorphism in 96.3% of SRNS and 100% of SSNS. There were no phenotypic or histologic characteristics of patients bearing homozygous R229Q polymorphism and the patients with heterozygous R229Q polymorphism. Conclusion. Polymorphism R229Q of NPHS2 gene is prevalent in Iraqi children with SRNS and SSNS. Further study needs to be done, for other exons and polymorphism of NPHS2 gene in those patients.

Background The results from the published studies on the association between angiotensin-converting enzyme (ACE) insertion/deletion (I/D) gene polymorphism and the treatment response to steroid in Asian children with idiopathic nephrotic syndrome (INS) is still conflicting. This meta-analysis was performed to evaluate the relation between ACE I/D gene polymorphism and treatment response to steroid in Asian children and to explore whether ACE D allele or DD genotype could become a predictive marker for steroid responsiveness. Methodology/Principal Findings Association studies were identified from the databases of PubMed, Embase, Cochrane Library and CBM-disc (China Biological Medicine Database) as of September 1, 2010, and eligible investigations were synthesized using meta-analysis method. Five investigations were identified for the analysis of association between ACE I/D gene polymorphism and steroid-resistant nephrotic syndrome (SRNS) risk in Asian children and seven studies were included to explore the relationship between ACE I/D gene polymorphism and steroid-sensitive nephrotic syndrome (SSNS) susceptibility. Five investigations were recruited to explore the difference of ACE I/D gene distribution between SRNS and SSNS. There was no a markedly association between D allele or DD genotype and SRNS susceptibility or SSNS risk, and the gene distribution differences of ACE between SRNS and SSNS were not statistically significant. II genotype might play a positive role against SRNS onset but not for SSNS (OR = 0.51, P = 0.02; OR = 0.95, P = 0.85; respectively), however, the result for the association of II genotype with SRNS risk was not stable. Conclusions/Significance Our results indicate that D allele or DD homozygous can't become a significant genetic molecular marker to predict the treatment response to steroid in Asian children with INS.

Low serum level of IgG, complement C3 and C4 in nephrotic syndrome children may cause increased susceptibility to infection. Serum level of IgG and complements in nephrotic children (NS) with UTI has been analyzed in this cross sectional study. It was carried out in the department of Pediatric nephrology, National Institute of Kidney Diseases & Urology (NIKDU), Dhaka, Bangladesh. The study subjects were followed up prospectively for one year to see and compare the frequency of relapse of NS and UTI. Patients were selected in a nonrandom purposive technique. Nephrotic syndrome children with initial attack between 1-12 year of age were included over a period of one year. The patients were grouped into Group I - UTI positive and Group II - UTI negative depending on urine culture positivity and colony count >10⁵ CFU/ml. Serum IgG and complements C3, C4 levels were done in both groups during nephrosis and were compared. A total of 101 children M: F 1.7:1, mean age 5.96±3.2 years were included in this study. Group I, n=45 vs. Group II, n=56. The mean serum level of IgG was low in Group I (549.91±210.71 vs. 728.64±235.81mg/dl, pUTI in nephrotic children. Higher number of children in Group II were at remission (n=24) during follow up, while frequent relapsers were high in Group I (n=22). Increased frequency of UTI attack (88 episodes) was found in Group I children compared to none in Group II during follow up. So low serum level of IgG in children with NS during nephrosis can predict UTI with an odds ratio of 6.63 as well as relapse. Serum level of C3, C4 do not associated with any risk of development of UTI in NS children.

Reduced activity of 11beta-hydroxysteroid dehydrogenase type 2 is not responsible for sodium retention in nephrotic rats

DEFF Research Database (Denmark)

Bistrup, C; Thiesson, H C; Jensen, B L

2005-01-01

AIM: In mineralocorticoid target cells 11-beta-hydroxysteroid dehydrogenase type 2 (11betaHSD2) converts glucocorticoids into non-active metabolites thereby protecting the mineralocorticoid receptor (MR) from stimulation by glucocorticoids. In nephrotic syndrome, a decreased activity of 11betaHSD2...... has been suggested to allow glucocorticoids to stimulate MR, thereby contributing to sodium retention. We tested this hypothesis in the puromycin aminonucleoside model of nephrotic syndrome in rats. METHODS: Complete sodium and potassium intakes and excretions (faeces and urine) were measured in rats......)] to suppress endogenous glucocorticoids in the proteinuric stage during active sodium retention. RESULTS: Nephrotic rats developed proteinuria, positive sodium balance, decreased plasma aldosterone concentration, and decreased urinary Na(+)/K(+) ratio. 11betaHSD2 mRNA expression was down-regulated but protein...

2007-07-01

A 04 years old boy with 02 months history of generalized oedema and scanty micturition was diagnosed as nephrotic syndrome with hepatitis B viral infection. He had evidence of active viral replication. After 01 month treatment with oral lamivudine, his urine became protein free and after 04 months, he had seroconversion from HBeAg+ve to HBeAg-ve. Lamivudine was continued for 01 year. He had no relapse after discontinuation of therapy and remained well after 36 months of completion of therapy. He had no evidence of active viral replication during this period, however HBsAg remained positive indication carrier state. As most children with HBV associated nephropathy have no evidence of chronic hepatitis, all such children must undergo HBV screening and for chronic liver disease if HBV screening is positive. As such children do not respond to prednisolone or other immunosuppresive therapy which might harm them, antiviral therapy should be considered. Lamivudine is a suitable alternative to IFN alpha owing to its low cost, ease of administration and fewer side effects.

Nucleotide excision repair (NER) is an essential biological pathway protecting against ultraviolet light-induced DNA damage. Deficient NER causes a group of rare genetic disorders including two autosomal recessive diseases, xeroderma pigmentosum (XP) and Cockayne syndrome (CS). In addition to the cutaneous photosensitivity shared in XP and CS, CS is featured by growth failure, neurological deterioration, microcephaly, and deep sunken eyes. XP/CS complex is an extremely rare type of NER disorder with a distinct phenotype that is characterized by the skin and eye pathology of XP and the somatic and neurological abnormalities of CS. Some of CS cases have been reported to be complicated with renal failure, but the genetic background or the etiology of the renal failure has not been reported. We herein report a 1-year-old Japanese boy with XP/CS complex, complicated by nephrotic syndrome. Diagnosis was confirmed by the presence of compound heterozygous mutations, G47R (c.139G>A) and R616G (c.1846C>G), in the excision repair cross-complementation group 2 (ERCC2) gene. The kidney biopsies, performed at the age of 1 year and 2 months, revealed diffuse expansion of the mesangial matrix and segmental glomerulosclerosis under light microscopy, and diffused thin capillary walls with partially lamellated regions under electron microscopy. Notably, high levels of urinary 8-hydroxy-2'-deoxyguanosin, known as an oxidative stress marker, were observed during the clinical course. The patient died at the age of 1 year and 11 months because of renal failure. We suggest the involvement of oxidative stress in the pathogenesis of nephrotic syndrome in NER disorders.

Retroperitoneal Bleeding: An Experience During Prophylactic Anticoagulation in a Patient With Nephrotic Syndrome

Directory of Open Access Journals (Sweden)

Mari Okada

2017-07-01

Full Text Available The association between nephrotic syndrome (NS and a hypercoagulable state has been demonstrated. Controlling the blood clotting activity may therefore be attractive for patients with nephrosis in terms of thromboembolism prophylaxis. We herein report a 75-year-old woman with minimal change disease who developed pains in the right back, groin, and thigh because of retroperitoneal bleeding during prophylactic anticoagulation with unfractionated heparin. Although this procedure has not been accepted as the standard of care for patients with nephrosis, pharmacologic prophylaxis may already be practiced empirically, as in the present patient. We believe that our experience highlights the pitfalls of such a management in patients with nephrosis, implying the need for a diagnostic strategy for identifying those patients with NS who can benefit from prophylactic anticoagulation. Several concerns that emerged in this case are also discussed.

Serum lipoprotein(a) [Lp(a)] concentration was determined in 42 patients with primary nephrotic syndrome (NS) and the relationships between Lp (a) and plasma lipids, apolipoproteins, serum creatinine (Scr), albumin, urinary proteins (Upro) were also analyzed. The results showed that: (1) serum Lp(a) concentrations in the patients with NS were higher than those in healthy controls; (2) the levels of serum Lp(a) were correlated positively with total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), very low density lipoprotein cholesterol (VLDL-C), apolipoprotein B (Apo-B), Upros (Upro). It is concluded that the NS patients had the potential risk of suffering from coronary artery disease, glomerular sclerosis and thrombosis. The remission of NS may partially decrease the serum Lp(a) levels. Further studies are needed to explore the prevention and treatment of dislipedemia in patients with NS.

Steroid Resistant Nephrotic Syndrome (SRNS) in children and young adults has differing etiologies with monogenic disease accounting for 2.9-30% in selected series. Using whole exome sequencing we sought to stratify a national population of children with SRNS into monogenic and non-monogenic forms, and further define those groups by detailed phenotypic analysis. Pediatric patients with SRNS were identified via a national United Kingdom Renal Registry. Whole exome sequencing was performed on 187 patients, of which 12% have a positive family history with a focus on the 53 genes currently known to be associated with nephrotic syndrome. Genetic findings were correlated with individual case disease characteristics. Disease causing variants were detected in 26.2% of patients. Most often this occurred in the three most common SRNS-associated genes: NPHS1, NPHS2, and WT1 but also in 14 other genes. The genotype did not always correlate with expected phenotype since mutations in OCRL, COL4A3, and DGKE associated with specific syndromes were detected in patients with isolated renal disease. Analysis by primary/presumed compared with secondary steroid resistance found 30.8% monogenic disease in primary compared with none in secondary SRNS permitting further mechanistic stratification. Genetic SRNS progressed faster to end stage renal failure, with no documented disease recurrence post-transplantation within this cohort. Primary steroid resistance in which no gene mutation was identified had a 47.8% risk of recurrence. In this unbiased pediatric population, whole exome sequencing allowed screening of all current candidate genes. Thus, deep phenotyping combined with whole exome sequencing is an effective tool for early identification of SRNS etiology, yielding an evidence-based algorithm for clinical management.

Pathophysiology, Evaluation, and Management of Edema in Childhood Nephrotic Syndrome.

Science.gov (United States)

Ellis, Demetrius

2015-01-01

Generalized edema is a major presenting clinical feature of children with nephrotic syndrome (NS) exemplified by such primary conditions as minimal change disease (MCD). In these children with classical NS and marked proteinuria and hypoalbuminemia, the ensuing tendency to hypovolemia triggers compensatory physiological mechanisms, which enhance renal sodium (Na(+)) and water retention; this is known as the "underfill hypothesis." Edema can also occur in secondary forms of NS and several other glomerulonephritides, in which the degree of proteinuria and hypoalbuminemia, are variable. In contrast to MCD, in these latter conditions, the predominant mechanism of edema formation is "primary" or "pathophysiological," Na(+) and water retention; this is known as the "overfill hypothesis." A major clinical challenge in children with these disorders is to distinguish the predominant mechanism of edema formation, identify other potential contributing factors, and prevent the deleterious effects of diuretic regimens in those with unsuspected reduced effective circulatory volume (i.e., underfill). This article reviews the Starling forces that become altered in NS so as to tip the balance of fluid movement in favor of edema formation. An understanding of these pathomechanisms then serves to formulate a more rational approach to prevention, evaluation, and management of such edema.

Mitra, Sulagna; Banerjee, Sushmita

The objective of our study was to assess the psychologic and economic effects of pediatric nephrotic syndrome (NS) on caregivers. Caregivers of 50 children with NS were compared with a control group of 50 families of children with minor illnesses attending the same outpatient facility. Beck's Depression Inventory (BDI) IA was used to assess the mental status of the primary caregiver. The socioeconomic status of the family was assessed using the modified Kuppuswamy scale. Expenditure for the illness was calculated during parent interviews. The difference between groups was analyzed using analysis of variance (ANOVA) and Duncan's multiple range test. BDI scores signified moderate to severe depression in 48% of NS caregivers compared with 12% controls. The mean BDI score was significantly higher in NS caregivers, correlating positively with disease severity and negatively with socioeconomic status. Expenditure for disease also was significantly higher in families with NS patients, varying between 30% and 60% of monthly income depending on disease severity compared with 6.9% in controls. In 10% of NS families, it was more than total income, forcing families to break into savings or go into debt. Although pediatric NS most commonly has an excellent long-term outcome, it causes significant mental and economic stress on families. Severe forms should be categorized as a chronic illness and be eligible for disability benefits and subsidized travel and medical care. Establishing support groups and supportive care at local levels would help reduce the burden on families of patients wtih NS.

Nephroprotective effect of heparanase in experimental nephrotic syndrome.

Directory of Open Access Journals (Sweden)

Suheir Assady

Full Text Available Heparanase, an endoglycosidase that cleaves heparan sulfate (HS, is involved in various biologic processes. Recently, an association between heparanase and glomerular injury was suggested. The present study examines the involvement of heparanase in the pathogenesis of Adriamycin-induced nephrotic syndrome (ADR-NS in a mouse model.BALB/c wild-type (wt mice and heparanase overexpressing transgenic mice (hpa-TG were tail-vein injected with either Adriamycin (ADR, 10 mg/kg or vehicle. Albuminuria was investigated at days 0, 7, and 14 thereafter. Mice were sacrificed at day 15, and kidneys were harvested for various analyses: structure and ultrastructure alterations, podocyte proteins expression, and heparanase enzymatic activity.ADR-injected wt mice developed severe albuminuria, while ADR-hpa-TG mice showed only a mild elevation in urinary albumin excretion. In parallel, light microscopy of stained cross sections of kidneys from ADR-injected wt mice, but not hpa-TG mice, showed mild to severe glomerular and tubular damage. Western blot and immunofluorescence analyses revealed significant reduction in nephrin and podocin protein expression in ADR-wt mice, but not in ADR-hpa-TG mice. These results were substantiated by electron-microscopy findings showing massive foot process effacement in injected ADR-wt mice, in contrast to largely preserved integrity of podocyte architecture in ADR-hpa-TG mice.Our results suggest that heparanase may play a nephroprotective role in ADR-NS, most likely independently of HS degradation. Moreover, hpa-TG mice comprise an invaluable in vivo platform to investigate the interplay between heparanase and glomerular injury.

To observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia. Totally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups. Compared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05). Treatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

Abstract Mutations in COQ8B cause steroid‐resistant nephrotic syndrome with variable neurological involvement. In yeast, COQ8 encodes a protein required for coenzyme Q (CoQ) biosynthesis, whose precise role is not clear. Humans harbor two paralog genes: COQ8A and COQ8B (previously termed ADCK3 and ADCK4). We have found that COQ8B is a mitochondrial matrix protein peripherally associated with the inner membrane. COQ8B can complement a ΔCOQ8 yeast strain when its mitochondrial targeting sequenc...

Albumin and Furosemide Combination for Management of Edema in Nephrotic Syndrome: A Review of Clinical Studies

Directory of Open Access Journals (Sweden)

Margaret Duffy

2015-10-01

Full Text Available The treatment of edema in patients with nephrotic syndrome is generally managed by dietary sodium restriction and loop diuretics. However, edema does not improve in some patients despite adequate sodium restriction and maximal dose of diuretics. In such patients, combination of albumin and a loop diuretic may improve edema by diuresis and natriuresis. The response to this combination of albumin and a diuretic has not been observed in all studies. The purpose of this review is to discuss the physiology of diuresis and natriuresis of this combination therapy, and provide a brief summary of various studies that have used albumin and a loop diuretic to improve diuretic-resistant edema. Also, the review suggests various reasons for not observing similar results by various investigators.

Galloway-Mowat syndrome (GAMOS) is a severe autosomal-recessive disease characterized by the combination of early-onset steroid-resistant nephrotic syndrome (SRNS) and microcephaly with brain anomalies. To date, mutations of WDR73 are the only known monogenic cause of GAMOS and in most affected individuals the molecular diagnosis remains elusive. We here identify recessive mutations of OSGEP, TP53RK, TPRKB, or LAGE3, encoding the 4 subunits of the KEOPS complex in 33 individuals of 30 families with GAMOS. CRISPR/Cas9 knockout in zebrafish and mice recapitulates the human phenotype of microcephaly and results in early lethality. Knockdown of OSGEP, TP53RK, or TPRKB inhibits cell proliferation, which human mutations fail to rescue, and knockdown of either gene activates DNA damage response signaling and induces apoptosis. OSGEP and TP53RK molecularly interact and co-localize with the actin-regulating ARP2/3 complex. Furthermore, knockdown of OSGEP and TP53RK induces defects of the actin cytoskeleton and reduces migration rate of human podocytes, an established intermediate phenotype of SRNS. We thus identify 4 novel monogenic causes of GAMOS, describe the first link between KEOPS function and human disease, and delineate potential pathogenic mechanisms. PMID:28805828

Hyper-activation of Rac1, a small GTPase, in glomerular podocytes has been implicated in the pathogenesis of familial proteinuric kidney diseases. However, the role of Rac1 in acquired nephrotic syndrome is unknown. To gain direct insights into this, we generated a transgenic mouse model expressing a doxycycline-inducible constitutively active form of Rac1 (CA-Rac1) in podocytes. Regardless of the copy number, proteinuria occurred rapidly within five days, and the histology resembled minimal change disease. The degree and severity of proteinuria were dependent on the transgene copy number. Upon doxycycline withdrawal, proteinuria resolved completely (one copy) or nearly completely (two copy). After one month of doxycycline treatment, two-copy mice developed glomerulosclerosis that resembled focal segmental glomerulosclerosis (FSGS) with urinary shedding of transgene-expressing podocytes. p38 MAPK was activated in podocytes upon CA-Rac1 induction while a p38 inhibitor attenuated proteinuria, podocyte loss, and glomerulosclerosis. Mechanistically, activation of Rac1 in cultured mouse podocytes reduced adhesiveness to laminin and induced redistribution of β1 integrin, and both were partially reversed by the p38 inhibitor. Activation of Rac1 in podocytes was also seen in kidney biopsies from patients with minimal change disease and idiopathic FSGS by immunofluorescence while sera from the same patients activated Rac1 in cultured human podocytes. Thus, activation of Rac1 in podocytes causes a spectrum of disease ranging from minimal change disease to FSGS, due to podocyte detachment from the glomerular basement membrane that is partially dependent on p38 MAPK.

To evaluate the frequency of non-autoimmune subclinical and overt hypothyroidism in children with idiopathic steroid-resistant nephrotic syndrome (SRNS). This cross-sectional study recruited 30 children (age 1-18 y) with idiopathic SRNS; and 30 healthy controls. Serum T3, T4 and TSH were performed in cases as well as controls. Anti-thyroid peroxidase and anti-thyroglobulin antibody tests were performed in all cases. Non-autoimmune subclinical or overt hypothyroidism was detected in 10 out of 30 children with idiopathic SRNS; 2 had overt hypothyroidism, while 8 patients had subclinical hypothyroidism. Children with SRNS had a mean (SD) TSH value 4.55 (4.64) mIU/L that was higher as compared to controls (1.88 (1.04) mIU/L) (Phypothyroidism (2 cases) and grade III subclinical hypothyroidism (1 case) were subsequently started on levothyroxine therapy. The prevalence of subclinical and overt hypothyroidism seems to be high in idiopathic SRNS, with almost one-third of children having overt or subclinical non-autoimmune hypothyroidism.

Full Text Available Schistosomal nephropathy has long been related to the hepatosplenic form of schistosomiasis. In the last few years, 24 patients with hepatointestinal schistosomiasis and the nephrotic syndrome were studied. Aiming at evaluating a possible etiologic participation of schistosomiasis in the development of the nephropathy, this group was comparatively studied with a group of 37 patients with idiopathic nephrotic syndrome. Both groups had a different distribution of the histologic lesions. In the group with schistosomiasis there was a statistically significant prevalence of proliferative mesangial glomerulonephritis (33.3%, whereas in the control group there was prevalence of membranous glomerulonephritis (32.4%. On immunofluorescence, IgM was positive in 94.4% of the patients with schistosomiasis versus 55.0% in the control group (pA nefropatia esquistossomótica está classicamente vinculada à fornia hepatoesplênica da esquistossomose.

Acute kidney injury (AKI) is an important complication of idiopathic nephrotic syndrome (INS) and is associated with adverse outcomes, especially the development of chronic kidney disease (CKD). We aimed to determine the clinical profile of children with INS who developed AKI and its short-term outcome. This prospective study was conducted from March 2014 to October 2015. A total of 119 children of INS (age: 2-18 years) fulfilling the pediatric RIFLE criteria for the diagnosis of AKI were enrolled and followed up for 3 months to determine the outcome. Factors predisposing to CKD were studied. The mean age at presentation was 8.8 ± 3.59 years and males were 74 (62.2%). At presentation, 61 (51.3%) children were in Risk category, 43 (36.1%) in Injury category, and 15 (12.6%) in Failure category. Most of them (41.2%) had steroid-resistant nephrotic syndrome (SRNS) and focal segmental glomerulosclerosis (FSGS) on histopathology (33.6%). Infections were the major predisposing factor for AKI in 67 (56.3%) cases. Drug toxicity was the next common, found in 52 (43.7%) children. A total of 65 (54.6%) children recovered from AKI, while 54 (45.4%) did not. CKD developed in 49 (41.2%) non-recovered cases and 5 (4.2%) children succumbed to acute illness. SRNS, cyclosporine use, FSGS on histology, and drug toxicity were significant factors associated with the development of CKD. AKI associated with INS is a reversible condition in most cases but it can progress to CKD, especially among those who have SRNS, FSGS, and drug toxicity.

Full Text Available For the last decade a great successes were attained in the study of molecular bases of glomerular diseases. It was certain that the most frequent reasons of congenital and infantile nephrotic syndrome are mutations in the genes of NPHS1, NPHS2, and WT1. Nevertheless, until now, a number of patients, having combination of early nephrotic syndrome with inherent pathology of other organs, which etiology remains un known. These cases continue to be intensively probed. One of the most important recent achievements in understanding of molecular mechanisms of early nephrotic syndrome is the discovery of mutations of gene of LAMB2, encoding β2 laminin, as the cause of Pearson syndrome (OMIM#609049. In this article the author presents the basic genetic and clinical descriptions of this recently identified pathology.

Background and objective: Severe edema in children with nephrotic syndrome (NS) may be associated with volume contraction (VC) or volume expansion (VE). Usually, severe edema in children is treated with intravenous (IV) albumin and diuretics, which is appropriate for VC patients. However, in VE patients, this can precipitate fluid overload. The objective of this study was to evaluate treatment of severe edema in NS with diuretics alone. Design, setting, participants, & measurements: Thirty NS patients with severe edema were enrolled in this prospective study in two phases. VC was diagnosed based on fractional excretion of sodium (FeNa) diuretics alone and 9 VC patients received albumin and furosemide. There was no difference in hospital stay and weight loss in VC and VE groups after treatment. Conclusions: FeNa is useful in distinguishing VC versus VE in NS children with severe edema. The use of diuretics alone in VE patients is safe and effective. PMID:19406963

Neuromyelitis optica (NMO) and NMO spectrum disorder (NMOSD) is a rare relapsing autoimmune disease of the central nervous system constituting less than 1% of demyelinating diseases (Jeffery and Buncic, 1996). It preferentially affects the optic nerves and spinal cord, with the brain parenchyma generally spared. Demyelinating lesions are characterised by longitudinally extensive transverse myelitis (LETM) and often longitudinally extensive optic neuritis. Following the discovery of a novel pathogenic antibody, Aquaporin 4 in 2004 (Lennon et al., 2004) this disease has been seen as a separate entity from Multiple Sclerosis (MS). We report the case of a severe AQP4 IgG case of NMO in a 10 year old child. This case unusually had a coexisting diagnosis of acute nephrotic syndrome which has only been reported once previously in the literature 2 . This article will examine some of the treatment challenges and the spectrum of co-existing autoimmune disease in NMOSD. Copyright © 2017. Published by Elsevier B.V.

Arthropathy and proteinuria: nail-patella syndrome revisited

Albishri, Jamal

2014-11-01

Full Text Available [english] Nail-patella syndrome (NPS is a pleiotropic autosomal-dominant disorder due to mutations in the gene LMX1B. It has traditionally been characterized by a tetrad of dermatologic and musculoskeletal abnormalities. However, one of the most serious manifestations of NPS is kidney disease, which may be present in up to 40% of affected individuals. Although diagnosis can be made at birth, it is often missed, presumably due to the rarity of the condition. A 35-year-old female presented to our clinic with history of small joint pain of 6 months duration. In addition she complained of pedal edema off and on for the last 12 years. Prior to her current presentation she had been managed by a local doctor symptomatically. On evaluation, a nephrotic syndrome was obvious, but no secondary cause could be found. However, her physical examination was characteristic of NPS and keeping in view the autosomal dominant nature of the disorder all her three siblings were screened who too showed classical features of NPS. This rare syndrome as a cause of nephrotic range proteinuria is discussed in this report. The report underlines the importance of a good physical examination in a given clinical setting.

Objective: To determine the frequency and clinicopathological correlations of focal segmental glomerulosclerosis variants in adolescents with idiopathic nephrotic syndrome. Methods: All consecutive adolescents (12 to 18 years) who presented with idiopathic nephrotic syndrome in the period, January 2009 to December 2012, and in whom the histological diagnosis of focal segmental glomerulosclerosis was made on renal biopsies, were included in this prospective study. Their clinical, laboratory and histopathological features at the time of presentation or biopsy were noted from the case files and the biopsy reports. Results: Among 50 adolescents, 34 (68%) were males and 16 (32%) females. The mean age was 15.14+-2.3 years. The mean duration of disease was 6.3+-11.2 months. The mean serum creatinine was 0.96+-0.82 mg/dl. The mean 24-hour urinary protein excretion was 3.8+-0.68 grams. Biopsy indications were steroid-resistant nephritic syndrome in 15 (30%), steroid-dependant nephritic syndrome in 19 (38%) and adolescent nephritic syndrome in 16 (32%) cases. Among the focal segmental glomerulosclerosis variants, 40 (80%) were not otherwise specified, followed by the collapsing variant, which accounted for 8 (16%) cases. The tip and cellular variants, both were found in one (2%) case each. Among the histological features, global glomerulosclerosis was found in 23 (46%) cases, and segmental scarring/collapse in all (100%). A variable degree of tubular atrophy and interstitial fibrosis was noted in 44 (88%) cases. Conclusion: The results from this study indicate that the pattern of focal segmental glomerulosclerosis variants differs markedly in adolescents compared with younger children. (author)

Full Text Available Idiopathic membranous nephropathy (IMN is the most common pathological type for nephrotic syndrome in adults in western countries and China. The benefits and harms of immunosuppressive treatment in IMN remain controversial.To assess the efficacy and safety of different immunosuppressive agents in the treatment of nephrotic syndrome caused by IMN.PubMed, EMBASE, Cochrane Library and wanfang, weipu, qinghuatongfang, were searched for relevant studies published before December 2011. Reference lists of nephrology textbooks, review articles were checked. A meta-analysis of randomized controlled trials (RCTs meeting the criteria was performed using Review Manager.17 studies were included, involving 696 patients. Calcineurin inhibitors had a better effect when compared to alkylating agents, on complete remission (RR 1.61, 95% CI 1.13, to 2.30 P = 0.008, partial or complete remission (effective (CR/PR, RR 1.29, 95% CI 1.09 to 1.52 P = 0.003, and fewer side effects. Among calcineurin inhibitors, tacrolimus (TAC was shown statistical significance in inducing more remissions. When compared to cyclophosphamide (CTX, leflunomide (LET showed no beneficial effect, mycophenolate mofetil (MMF showed significant beneficial on effectiveness (CR/PR, RR: 1.41, 95% CI 1.16 to 1.72 P = 0.0006 but not significant on complete remission (CR, RR: 1.38, 95% CI 0.89 to 2.13 P = 0.15.This analysis based on Chinese adults and short duration RCTs suggested calcineurin inhibitors, especially TAC, were more effective in proteinuria reduction in IMN with acceptable side effects. Long duration RCTs were needed to confirm the long-term effects of those agents in nephrotic IMN.

Sprague-Dawley rats received once daily tail-vein injections of 360 mM dibasic sodium phosphate solution at 8 mL/kg for fourteen or twenty-eight days. Clinical examination revealed persistent proteinuria from three days after the first dosing and thereafter severe proteinuria from eight days or later in the phosphate-treated groups. Proteinuria developed without remission even after fourteen-day withdrawal in the fourteen-day dosed group. Phosphate-treated animals developed lipemia, hypercholesterolemia, anemia, higher serum fibrinogen levels, and lower serum albumin/globulin ratios on day 29. Renal weight increased significantly compared with control animals, and the kidneys appeared pale and enlarged with a rough surface. Histopathologically, glomerular changes consisted of mineralization in whole glomeruli, glomerular capillary dilatation, partial adhesion of glomerular tufts to Bowman's capsule, and mesangiolysis. Ultrastructural lesions such as an increased number of microvilli, effacement of foot processes, and thickening of the glomerular basement membrane, and immunocytochemical changes in podocytes, mainly decreased podoplanin-positive cells and increased desmin expression, were also conspicuous in the phosphate-treated rats for twenty-eight days. Marked tubulointerstitial lesions were tubular regeneration and dilatation, protein casts, mineralization in the basement membrane, focal interstitial inflammation, and fibrosis in the cortex. These clinical and morphological changes were similar to features of human nephrotic syndrome.

Full Text Available Steroid resistant nephrotic syndrome (SRNS remains a challenge facing pediatric nephrologists. The underlying histopathology usually affects the course of the disease and the response to treatment. We studied the pattern of histopathology in children with SRNS who presented to the King Abdul Aziz University Hospital (KAUH, Jeddah, Saudi Arabia. The records of all children with primary SRNS, who were seen between 2002 and 2007 were reviewed. Only patients who had undergone a renal biopsy were included in the study. The histopathology slides were reviewed by two renal pathologists independently. Patients with congenital nephrotic syndrome, lupus or sickle cell disease, were excluded from the study. Thirty-six children fulfilled the inclusion criteria, and included 25 girls and 11 boys with female to male ratio of 2.3:1. Fifty percent of the children (n=18 were Saudi and the remaining 50% were from various other racial backgrounds (9 Asians, 4 Arabs, 2 Africans and 3 from the Far East. Their mean age at presentation was 4.3 ± 3.0 years (range 1-12 years. The mean serum albumin at presentation was 15.6 ± 7.1 g/L and all of them had 4+ proteinuria on urinalysis. Five children had elevated serum creatinine at presentation while the mean serum creatinine was 50.4 ± 45.6 µmol/L. Three children had low serum complement levels at presentation and none were positive for hepatitis B surface antigen or antinuclear antibody (ANA. The renal histopathology was compatible with focal and segmental glomerulosclerosis (FSGS in 39% (n=14, IgM nephro-pathy in 28% (n=10, mesengioproliferative glomerulonephritis (MesPGN in 17% (n=6, mini-mal change disease (MCD and C1q nephropathy (C1qNP in 8% each (n=3 + 3 and IgA nephro-pathy in 3% (n=1.

with steroid-sensitive nephrotic syndrome coexisting with type-1 diabetes mellitus. The interest to this clinical case is due to the unusual association of these diseases, the clinical symptoms and laboratory tests used to confirm diagnosis and the difficulties on corticotherapy. DESCRIPTION: Nephrotic syndrome was diagnosed in a boy (age 3 years and 11 months with generalized edema. Marked weight loss (23 to 16 kg, polyuria, polydipsia and weakness were observed after three weeks of treatment with prednisone 2 mg/kg/day. Diabetic ketoacidosis was confirmed by laboratory tests: hyperglycemia (glucose 657 mg/dl, glycosuria without proteinuria, acidosis and ketonuria. Therapy with insulin and prednisone was started. He was then maintained on a daily dose of NPH insulin. At age 4 years and 1 month a new episode of ketoacidosis without proteinuria occurred in association with a viral infection of the upper airways. At age 4 years and 4 months nephrotic syndrome relapsed, but the child responded well to steroid therapy. There was another relapse three months later, when prednisone treatment was interrupted. This led to the introduction of cyclophosphamide, with good results. Since then, the patient (now 5 years and 6 months old has been taking insulin daily and nephrotic syndrome has not relapsed. Plasma levels of C3 and C4 and renal function are normal. Hematuria is occasionally present. Anti-GAD antibodies (glutamic decarboxilase are normal and anti-islet cell antibodies are positive. HLA antigens: A2; B44; B52; DR4; DR8; DR53. COMMENTS: The simultaneous occurrence of steroid-sensitive nephrotic syndrome and type-1 diabetes mellitus is rare. The literature data, the familiar pattern and studies on HLA antigens are discussed.

Experimental and clinical studies have demonstrated a positive relationship between hyperlipidemia and rate of progression of renal disease, suggesting that lipids can induce or aggravate glomerular injury mainly by interacting with mesangial cells. Nevertheless, recently has been demonstrated that increased cholesterol levels can also induce endothelial cell dysfunction. Thus, since endothelium is known to play a major role in modulating the vascular tone, we have tested the possibility that hypercholesterolemia impairs the renal hemodynamics in patients with active nephrotic syndrome and elevated serum cholesterol levels. In this single-blind, nonrandom study, 12 patients were treated with pravastatin (group T, treated, n = 12) and 8 with placebo (group C, controls, n = 8). The controls were studied after the pravastatin group had been completed. Before starting the treatment the patients underwent basal determinations including routine laboratory investigations and PAH and inulin clearances. The same determinations were repeated after 48 h, and 6 and 12 weeks from the beginning of the treatment. The study at 48 h was performed to see if pravastatin had a direct, cholesterol-independent effect on renal function. The following basal results were reported (mean +/- SEM; group T vs. group C): serum cholesterol (mmol/l) 9.7 +/- 0.4 vs. 9.1 +/- 0.3 (NS); proteinuria (g/24 h): 6.2 +/- 0.2 vs. 7.0 +/- 0.7 (NS); PAH clearance (ml/min): 353 +/- 21 vs. 385 +/- 31 (NS); inulin clearance (ml/min): 62.5 +/- 7.7 vs. 67 +/- 9.3 (NS). After 48 h, no changes were observed in both groups. Subsequently, in group T, the following percentage changes of basal levels were observed: serum cholesterol -21.4 +/- 3.2% at 6 weeks (p < 0.05) and -34.9 +/- 3.2% at 12 weeks (p < 0.01); inulin clearance +3 +/- 3.7% at 6 weeks (NS) and +9.3 +/- 2.9% at 12 weeks (p < 0.05); PAH clearance +7 +/- 3.1% at 6 weeks (p < 0.05) and +21.2 +/- 5.5% at 12 weeks (p < 0.01).

Full Text Available Background Nephrotic syndrome (NS patients frequently have abnormalities in calcium metabolism that manifest as hypocalcemia and reduced intestinal absorption of calcium. Hypocalcemia is initially attributed to hypoalbuminemia but it may also relate to a low level of ionized calcium. The ionized calcium level depends on the severity and duration of proteinuria. Objective To assess the rel ationship between ionized calcium and serum albumin level in idiopathic NS children. Methods An analytical study with cross-sectional design was applied to NS and healthy children between 1-14 years old in the Child Health Department of Hasan Sadikin Hospital, Bandung from December 2009 to April 2010. Ionized calcium was examined by Ca2 + analyzer AVL 980 with ion-selective electrodes (ISE methods. Results A total of34 subjects were recruited, consist of 17 NS and 17 healthy children. The mean ionized calcium and serum albumin level in NS children was 4.56 (SD 0.23 mg/dLand 1.45 (SD 0.24 g/dL, respectively. Statistical difference between ionized calcium level in NS and in healthy children was significant (P<0.05. Pearson correlation test between ionized calcium and serum albumin was significant (P<0.05 with correlation coefficient (r 0.53. We found the following equation to estimate ionized calcium (y based on the serum albumin level (x: y=3.84+0.49x. Conclusion There is a moderately positive linear relationship between ionized calcium and serum albumin level in NS children.

Method: In the present study, the genotype and informative status of rs2274625 marker in NPHS2 genewas investigated in 120 unrelated healthy individuals using Tetra-primer ARMS PCR technique and newly designed primers. Allelic frequency and presence of Hardy Weinberg Equilibrium (HWE was estimated using GenePop website. Furthermore, PowerMarker software was utilized in order to compute the index of polymorphism information content (PIC. Results: The study results indicated allele frequency of 97% and 3% for C and T alleles, respectively, in regard with rs2274625 marker within Isfahan population. Moreover, the PIC for the rs2274625 marker was 0.5%, and HWE revealed the equilibruim of the study population in regard with the related marker. Conclusion: As the study findings indicated, rs2274625 could be introduced as an SNP marker in the linkage analysis in order to molecularly trace NPHS2 gene mutations in molecular NS diagnosis in Isfahan population as a representative sample of the Iranian population.

Full Text Available A middle-aged patient of Greenlandic origin was referred for skin infection of the leg. An initial minor trauma of the skin of the distal right lower extremity was complicated by bullous erysipelas which cultured positive for group A β-hemolytic streptococci (GABHS. The clinical condition deteriorated and necrotizing fasciitis developed despite relevant surgical and antibiotic treatment. Approximately 3 weeks later, the patient developed arthralgia, impaired renal function with azotemia, hypertension and severe nephrotic syndrome with periorbital and peripheral edema. A kidney biopsy demonstrated endocapillary glomerulonephritis. Concomitantly, carditis with chest pain, moderately reduced left ventricular ejection fraction and mitral regurgitation were noted. The patient had no signs of pharyngitis in the whole period. The patient thus contracted poststreptococ glomerulonephritis and furthermore she fulfilled the criteria of acute rheumatic fever following a GABHS skin infection. We suggest a possible relation between a virulent GABHS clone causing NF and ARF.

The purpose of the study was to investigate the distribution of insertion/deletion (I/D) polymorphisms of the angiotensin-converting enzyme (ACE) gene and three exonic polymorphisms of the multidrug resistance 1 (MDR1) gene (C3435T, C1236T, and G2677T) in children diagnosed with idiopathic nephrotic syndrome (INS). The study group consisted of 100 healthy controls and 150 INS patients, of which 50 were steroid resistant. Genomic DNA from blood samples was isolated from both of these groups and genotyping of the ACE and MDR1 genes was performed by polymerase chain reaction (PCR) using specific primers. There was no significant difference observed in the genotypic distribution and D allele frequency of the ACE gene. The two single-nucleotide polymorphisms (SNPs), C1236T and C3435T, of the MDR1 gene showed no significance, whereas the SNP G2677T/A was significantly associated with the genotypes GT and GA of the MDR1 gene, indicating it may be a potential marker to detect drug resistance. Screening these polymorphisms will pave the way to better understand the molecular mechanisms of the disease, which may be useful in developing targeted therapies for INS patients.

Full Text Available IntroductionBecause of their immunomodulatory and anti-inflammatory effects, mesenchymal stem cells (MSCs have been considered as potential therapeutic agents for treating immune-related or autoimmune diseases, such as graft-versus-host disease (GVHD. Nephrotic syndrome (NS after allogeneic hematopoietic stem cell transplantation (allo-HSCT is an uncommon complication with unclear etiology and pathogenesis. It may be an immune disorder involving immune complex deposition, B cells, regulatory T cells (Tregs, and Th1 cytokines and be a manifestation of chronic GVHD. Corticosteroids and calcium antagonists, alone or in combination, are the most common therapeutic agents in this setting. Rituximab is commonly administered as salvage treatment. However, treatment failure and progressive renal function deterioration has been reported to occur in approximately 20% of patients in a particular cohort.Case presentationWe present a patient who developed NS 10 months after allo-HSCT. After treatment failure with cyclosporine A, prednisone, and rituximab, she achieved a complete response with MSC treatment. The clinical improvement of this patient was accompanied by a decreased B cell population together with an increased frequency of regulatory B cells (Bregs and Tregs after MSC treatment.ConclusionMSCs could modulate NS after allo-HSCT by suppressing B cell proliferation, inducing Tregs and Bregs, and inhibiting inflammatory cytokine production by monocytes and NK cells. Among all these, Bregs might play an important role in ameliorating the NS of this patient.

Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to neoplasm. Paraneoplastic syndromes may be the first or the most prominent manifestations of cancer. Wilm's tumor is the most frequent pediatric renal malignancy and usually presents with abdominal mass. Unusual presentations like acquired von Willebrand disease, sudden death due to pulmonary embolism and Cushing syndrome have been described in the literature. Cushing syndrome, as the presenting symptom of a malignant renal tumor in children, is a very rare entity. Few case reports are available in the literature exploring the option of preoperative chemotherapy as well as upfront nephrectomy. We report a rare case of paraneoplastic Cushing syndrome due to a Wilm's tumor. Based on gradual decrease of postoperative weight, blood pressure, serum adrenocorticotropic hormone, and plasma cortisol levels, along with histological confirmation of Wilm's tumor, paraneoplastic Cushing syndrome due to Wilm's tumor was confirmed.

2012-01-01

It has been shown that angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism affects the circulating and cellular levels of ACE and may be a risk factor in several renal diseases. We analyzed the association of ACE gene I/D polymorphism with the clinical presentation of minimal change nephrotic syndrome (MCNS) in a Turkish child population. This study consisted of 97 children with MCNS and 144 healthy controls. Genotyping of ACE gene was performed using polymerase chain reaction (PCR). The distributions of ACE genotypes were II in 13%, ID in 49%, and DD in 38% in patient group, and 9%, 49%, and 42% in control group, respectively. The frequency of the D allele was 63% and that of the I allele was 37% in patients. There were no relevant differences in the allele frequencies and genotypes of ACE I/D polymorphism between patients and controls. However, DD genotype was higher in boys in children with MCNS (78.4%. vs. 50.0%, p = 0.004). The frequencies of DD genotype and D allele in boys were 7.25 and 2.56 times higher than II genotype and I allele in the patient group, respectively. We suggest that DD genotype in boys may be one of the risk factors for MCNS.

Dyslipidemia is common in nephrotic children and persistent lipid abnormalities are risk factor of late vascular complications. The aim of the study was evaluation of efficacy and safety of 12-months simvastatin therapy in nephrotic children with lipid profile abnormalities present despite clinical remission lasting for at least 8 weeks, including ultrasonographic assessment of carotid and femoral arteries. Overall 52 children (40 steroid-dependent and 12 steroid-resistant) were initially introduced to the study and 29 of them were treated with simvastatin. Normalisation of lipid profile was achieved in 19/29 (65.5%) and improvement in 9/29 (31%). Significant reduction in total cholesterol (p 2.0) was small. Increased cIMT was seen at baseline in 4 patients and in 5 after simvastatin treatment, however average and Z-score values in children under simvastatin treatment have decreased. Increased fIMT values were seen at baseline in 2 and in one case after simvastatin treatment. Tolerance of simvastation was very good in all cases but one. Simvastatin therapy was effective and safe in nephrotic non-proteinuric children with abnormal lipid profile. Fair estimation of impact of the 12-months simvastatin therapy on vascular status was not available due to limited number of children with significantly increased IMT at baseline.

The etiology of nephrotic syndrome (NS) in adults varies depending on the geographical location and is poorly studied in the Indian subcontinent. Patients (≥16 years old) with NS presenting to our center and undergoing a kidney biopsy from April 2010 to September 2012 were included for this study. All biopsies were subjected to light and immunofluorescence microscopy, and electron microscopy in selected cases. The histopathological spectrum was analyzed according to the various clinical parameters. A total of 410 kidney biopsies were included for analysis. Two hundred and thirty seven (57.8%) patients were male and 173 (42.19%) patients were female. The average age at presentation was 33.68 ± 13.88 years. Among the patients, 88.05% (n = 361) were diagnosed with primary glomerular diseases (PGD) and 11.95% (n = 49) with secondary glomerular diseases (SGD). The most common histological lesions were focal segmental glomerulosclerosis (FSGS) (24.63%) followed by minimal change disease (MCD) (23.9%) and membranous nephropathy (MN) (22.44%). The most common form of SGD was lupus nephritis (LN) (6.58% of all cases). FSGS (28.27%) and MCD (21.96%) were the most common lesions in males and females, respectively. In the age groups of 16-29 years, 30-59 years, and ≥60 years, MCD (28.96%), MN (24%), and MN (40.74%) were the most common lesions, respectively, followed by FSGS in all groups (25.68%, 24.5%, and 18.52%, respectively). Among the patients, 27.07% had serum creatinine ≥1.5 mg/dL and 28.54% had either macroscopic or microscopic hematuria. FSGS is increasingly becoming the most common cause of adult NS. This trend in Asia is seen predominantly in countries of the Indian subcontinent.

To date, very few cases with adult-onset focal segmental glomerulosclerosis (FSGS) carrying NPHS2 variants have been described, all of them being compound heterozygous for the p.R229Q variant and one pathogenic mutation. Mutation analysis was performed in 148 unrelated Spanish patients, of whom 50 presented with FSGS after 18 years of age. Pathogenicity of amino acid substitutions was evaluated through an in silico scoring system. Haplotype analysis was carried out using NPHS2 single nucleotide polymorphism and microsatellite markers. Compound heterozygous or homozygous NPHS2 pathogenic mutations were identified in seven childhood-onset steroid-resistant nephrotic syndrome (SRNS) cases. Six additional cases with late childhood- and adult-onset SRNS were compound heterozygotes for p.R229Q and one pathogenic mutation, mostly p.A284V. p.R229Q was more frequent among SRNS cases relative to controls (odds ratio=2.65; P=0.02). Significantly higher age at onset of the disease and slower progression to ESRD were found in patients with one pathogenic mutation plus the p.R229Q variant in respect to patients with two NPHS2 pathogenic mutations. NPHS2 analysis has a clinical value in both childhood- and adult-onset SRNS patients. For adult-onset patients, the first step should be screening for p.R229Q and, if positive, for p.A284V. These alleles are present in conserved haplotypes, suggesting a common origin for these substitutions. Patients carrying this specific NPHS2 allele combination did not respond to corticoids or immunosuppressors and showed FSGS, average 8-year progression to ESRD, and low risk for recurrence of FSGS after kidney transplant.

Full Text Available Background: Nephrotic syndrome (NS is a major clinical concern in human health, especially in children. Despite of the etiology, the prediction of remission in different treatment regimens based on suitable biomarkers is under development. The goal of this evaluation was the demonstration of correlation between serum level of Neutrophil gelatinase associated lipocalin (NGAL and cystatin-C with kidney function in patients with NS. Methods: During the period between September 2008 and December 2011, 52 patients admitted to St. Al Zahra University Hospital were selected for evaluation. The measured parameters consisted of NGAL, cystatin-C, creatinine, albumin, blood urea nitrogen, urine protein, glomerular filtration rate. Demographic data were collected and considered in comparisons. Comparison between variables and their correlations were examined. Results: Means of serum NGAL and cystatin-C were significantly higher in case than the control group, P < 0.05. The mean of serum NGAL in patients without remission and who achieved remission were 23.09 (standard deviation [SD] ±10.11 and 36.26 (SD ± 20.10 ng/ml respectively; P < 0.05. Serum NGAL levels had a correlation with the following factors: Systolic blood pressure, diastolic blood pressure (DBP, cystatin-C, remission. Linear regression analysis showed a significant correlation between cystatin-C and systolic and DBP. Conclusions: Based on the results, serum NGAL can be used as a prognostic marker for remission. In addition, NGAL and cystatin-C are biomarkers of kidney injury in NS.

Full Text Available Background Lacunar syndrome not due to lacunar infarct is poorly characterised. This single centre, retrospective study was conducted to describe the clinical characteristics of patients with lacunar syndrome not due to lacunar infarct and to identify clinical predictors of this variant of lacunar stroke. Methods A total of 146 patients with lacunar syndrome not due to lacunar infarction were included in the "Sagrat Cor Hospital of Barcelona Stroke Registry" during a period of 19 years (1986-2004. Data from stroke patients are entered in the stroke registry following a standardized protocol with 161 items regarding demographics, risk factors, clinical features, laboratory and neuroimaging data, complications and outcome. The characteristics of these 146 patients with lacunar syndrome not due to lacunar infarct were compared with those of the 733 patients with lacunar infarction. Results Lacunar syndrome not due to lacunar infarct accounted for 16.6% (146/879 of all cases of lacunar stroke. Subtypes of lacunar syndromes included pure motor stroke in 63 patients, sensorimotor stroke in 51, pure sensory stroke in 14, atypical lacunar syndrome in 9, ataxic hemiparesis in 5 and dysarthria-clumsy hand in 4. Valvular heart disease, atrial fibrillation, sudden onset, limb weakness and sensory symptoms were significantly more frequent among patients with lacunar syndrome not due to lacunar infarct than in those with lacunar infarction, whereas diabetes was less frequent. In the multivariate analysis, atrial fibrillation (OR = 4.62, sensorimotor stroke (OR = 4.05, limb weakness (OR = 2.09, sudden onset (OR = 2.06 and age (OR = 0.96 were independent predictors of lacunar syndrome not due to lacunar infarct. Conclusions Although lacunar syndromes are highly suggestive of small deep cerebral infarctions, lacunar syndromes not due to lacunar infarcts are found in 16.6% of cases. The presence of sensorimotor stroke, limb weakness and sudden onset in a patient

A 9-year-old female child was initially diagnosed of having nephrocalcinosis with distal renal tubular acidosis (dRTA) while investigating for short stature. She later on developed features of nephrotic syndrome (NS) while on treatment for RTA. Investigation for the cause of NS revealed very strong serological evidence in favor of systemic lupus erythematosus (SLE). Histopathological confirmation could not be done due to bilateral severely contracted kidneys. There are a few case reports of dRTA as the presentation of SLE, but nephrocalcinosis with dRTA with subsequent manifestation of SLE has hitherto not been reported in literature.

Noonan syndrome is characterised by short stature, typical facial dysmorphology and congenital heart defects. Urogenital abnormalities are reported in 10% of the cases. We present a 14-year-old girl with characteristic features of Noonan syndrome and nephrotic-range proteinuria. She had crossed fused ectopic kidneys. Renal biopsy showed focal segmental glomerulosclerosis. Oral steroids were instituted and she responded well. The case highlights this novel renal presentation of Noonan syndrome.

The association of the angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism with idiopathic nephrotic syndrome (INS) is controversial. Only scarce information on European populations is available. The aim of the study was to investigate the distribution of the ACE gene I/D polymorphism and its impact on INS in children from Croatia. Ninety-five children with INS were investigated: 30 with minimal change disease (MCD), 35 with mesangial proliferative glomerulonephritis (MesPGN) and 30 with focal segmental glomerulosclerosis (FSGS). The control group consisted of 73 healthy adults. ACE gene was analyzed using the PCR method. The results were correlated with clinical features, renal morphology and response to immunosuppresive therapy. There was no correlation of ACE genotype with gender, age of the disease onset, level of proteinuria, presence of hematuria or hypertension, and GFR at onset of the disease. No statistically significant differences in ACE genotype or allele frequencies between the controls and whole group of patients, MCD group, MesPGN group, FSGS group, steroid sensitive (SS) patients, steroid resistant (SR) patients, as well as each other, were found, although DD genotype tended to be more frequent in FSGS patients, SR patients, and frequent relapsers. Among 11 children treated with cyclophosphamide the D allele was significantly higher among non-responders (p = 0.003). DD genotype is not a genetic risk factor for acquiring INS nor significant phenotype modifier regarding to clinical and pathohistological picture and response to steroids in Croatian children. The potential application of ACE genotyping in predicting cyclophosphamide response deserves further investigation. © 2015 S. Karger AG, Basel.

Abstract Mutations in COQ8B cause steroid‐resistant nephrotic syndrome with variable neurological involvement. In yeast, COQ8 encodes a protein required for coenzyme Q (CoQ) biosynthesis, whose precise role is not clear. Humans harbor two paralog genes: COQ8A and COQ8B (previously termed ADCK3 and ADCK4). We have found that COQ8B is a mitochondrial matrix protein peripherally associated with the inner membrane. COQ8B can complement a ΔCOQ8 yeast strain when its mitochondrial targeting sequence (MTS) is replaced by a yeast MTS. This model was employed to validate COQ8B mutations, and to establish genotype–phenotype correlations. All mutations affected respiratory growth, but there was no correlation between mutation type and the severity of the phenotype. In fact, contrary to the case of COQ2, where residual CoQ biosynthesis correlates with clinical severity, patients harboring hypomorphic COQ8B alleles did not display a different phenotype compared with those with null mutations. These data also suggest that the system is redundant, and that other proteins (probably COQ8A) may partially compensate for the absence of COQ8B. Finally, a COQ8B polymorphism, present in 50% of the European population (NM_024876.3:c.521A > G, p.His174Arg), affects stability of the protein and could represent a risk factor for secondary CoQ deficiencies or for other complex traits.

The aim of the present study was to investigate whether the four guanosines (4G)/five guanosines (5G) polymorphism in the gene coding for plasminogen activator inhibitor-1 (PAI-1) affects the clinical features of primary nephrotic syndrome (PNS). A cohort of 200 biopsy-diagnosed PNS patients was studied, with 40 healthy subjects as controls. The PAI-1 gene polymorphism was detected by polymerase chain reaction and DNA sequencing. Associations between the PAI-1 4G/5G polymorphism and clinical features and pathological types of PNS were analyzed. The results indicated that the PAI-1 genotype distribution is significantly different between patients with PNS and healthy controls, with significantly higher numbers of the 4G/4G genotype and lower numbers of the 5G5G genotype detected in PNS patients compared to controls (both P5G genotypes, as well as of the 4G allele. The increased 4G frequency was also detected in patients with minimal change disease (MCD). Significantly increased international normalized ratio (INR) and prolonged activated partial thromboplastin time (APTT) were observed in 4G/4G compared to 5G/5G PNS subjects. The response to steroids was not significantly different among the three genotypes. In conclusion, the 4G allele of the PAI-1 gene appears to be associated with PNS, especially in MN and IgAN patients. These findings suggest that specific targeting may be required for the treatment of PNS patients with the 4G/4G genotype.

Background and objectives: Mutations in nephrin (NPHS1) and podocin (NPHS2) genes represent a major cause of idiopathic nephrotic syndrome (NS) in children. It is not yet clear whether the presence of a single mutation acts as a modifier of the clinical course of NS. Design, setting, participants, & measurements: We reviewed the clinical features of 40 patients with NS associated with heterozygous mutations or variants in NPHS1 (n = 7) or NPHS2 (n = 33). Long-term renal survival probabilities were compared with those of a concurrent cohort with idiopathic NS. Results: Patients with a single mutation in NPHS1 received a diagnosis before those with potentially nongenetic NS and had a good response to therapies. Renal function was normal in all cases. For NPHS2, six patients had single heterozygous mutations, six had a p.P20L variant, and 21 had a p.R229Q variant. Age at diagnosis and the response to drugs were comparable in all NS subgroups. Overall, they had similar renal survival probabilities as non-NPHS1/NPHS2 cases (log-rank χ2 0.84, P = 0.656) that decreased in presence of resistance to therapy (P < 0.001) and in cases with renal lesions of glomerulosclerosis and IgM deposition (P < 0.001). Cox regression confirmed that the only significant predictor of dialysis was resistance to therapy. Conclusions: Our data indicate that single mutation or variant in NPHS1 and NPHS2 does not modify the outcome of primary NS. These patients should be treated following consolidated schemes and have good chances for a good long-term outcome. PMID:19406966

Mugwort-Mustard Allergy Syndrome due to Broccoli Consumption

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available Pollen-food allergy syndrome (PFAS is a relatively rare form of food allergy which develops in individuals who are sensitized to pollen. Tree pollens, especially birch pollen, frequently induce PFAS; however, the incidence of PFAS due to grass or weed pollens such as ragweed or mugwort is relatively rare. Mugwort-mustard allergy syndrome (MMAS is an example of a PFAS in which individuals sensitized to mugwort may develop an allergy to mustard and experience severe reactions. We herein describe a case of MMAS due to broccoli consumption.

Patients with diabetic nephropathy develop nephrotic syndrome, and may show limited response to conventional therapy. They often require earlier initiation of renal replacement therapy because they become refractory to diuretics, and experience excessive fluid retention. We aimed to investigate the efficacy of tolvaptan, an oral arginine vasopressin type 2 receptor antagonist, in a case series of 14 severe diabetic renal failure patients who were severely refractory to maximal doses of furosemide and had excessive fluid retention despite preserved cardiac function and residual renal function. All 14 patients experienced immediate and sustained water diuretic effects, resulting in alleviation of congestive heart failure. None required initiation of renal replacement therapy. Tolvaptan promptly increased urine volume and free water clearance, reversed progressive fluid retention, and alleviated congestive heart failure. Thus, tolvaptan could serve as a potential adjunct therapy for severe diabetic renal failure patients with excessive fluid retention and congestive heart failure.

To investigate the spectrum and drug sensitivity of pathogenic bacteria in children with nephrotic syndrome (NS) complicated by urinary tract infection (UTI). A retrospective analysis was performed on the spectrum and drug sensitivity of pathogenic bacteria in 97 children with NS complicated by UTI, who hospitalized from January to December, 2011. The incidence of UTI in children with NS was 36.5%. It was significantly more common in children with recurrent NS than in those with primary NS (44.0% vs 31.9%; Ppathogenic bacteria (50.5%), including Enterococcus faecium (29.4%) and Enterococcus faecalis (21.1%), followed by Gram-negative bacteria, such as Escherichia coli (15.6%) and Klebsiella pneumoniae (14.7%). Enterococcus was highly sensitive to nitrofurantoin, vacomycin and linezolid, but was highly resistant to tetracycline and moxifloxacin. More multi-resistant strains were detected in Enterococcus faecium than in Enterococcus faecalis (72% vs 17%; Pbacteria, 25% produced extended spectrum β-lactamases (ESBLs). ESBLs-producing bacteria had 100% sensitivity to imipenem, amikacin and piperacillin/tazobactam but were highly resistant to ampicillin, cefazolin and ceftriaxone. Children with recurrent NS are more susceptible to UTI than those with primary NS. Enterococcus is becoming major pathogenic bacteria for UTI in children with NS and has relatively high drug resistance, and most strains of Enterococcus faecium are multi-resistant.

Mutations in COQ8B cause steroid-resistant nephrotic syndrome with variable neurological involvement. In yeast, COQ8 encodes a protein required for coenzyme Q (CoQ) biosynthesis, whose precise role is not clear. Humans harbor two paralog genes: COQ8A and COQ8B (previously termed ADCK3 and ADCK4). We have found that COQ8B is a mitochondrial matrix protein peripherally associated with the inner membrane. COQ8B can complement a ΔCOQ8 yeast strain when its mitochondrial targeting sequence (MTS) is replaced by a yeast MTS. This model was employed to validate COQ8B mutations, and to establish genotype-phenotype correlations. All mutations affected respiratory growth, but there was no correlation between mutation type and the severity of the phenotype. In fact, contrary to the case of COQ2, where residual CoQ biosynthesis correlates with clinical severity, patients harboring hypomorphic COQ8B alleles did not display a different phenotype compared with those with null mutations. These data also suggest that the system is redundant, and that other proteins (probably COQ8A) may partially compensate for the absence of COQ8B. Finally, a COQ8B polymorphism, present in 50% of the European population (NM_024876.3:c.521A > G, p.His174Arg), affects stability of the protein and could represent a risk factor for secondary CoQ deficiencies or for other complex traits. © 2017 The Authors.

1984-01-01

To determine the role of platelets in the genesis of renal transplant (T) rejection, the authors studied 3 groups of adult patients. Group I, n=8, had normal renal function (Cr=1 +- 0.1 mg%, Mean +- SD). Group II, n=9, had nephrotic syndrome (Cr=2.4 +- 1). Group III, n=7, consisted of 5 cadaveric (C) and 2 living related donor (LRD) T. In Group II, 1 patient had received a T 4 years prior to study. Group I and II received 448 +- 101 μCi and Group III 236 +- 51 μCi of Indium-111. In Groups I and II the first image was obtained 18 +- 6 hrs after injection. In Group II the first was obtained 6 +- 2 hr after injection and 1-3 times/day thereafter for a maximum of 7 days. Renal biopsies were obtained in all patients in Group III during imaging (n=5) or within 2 - 5 days of the last image. One patient was studied twice. In Group III, 5 patients received prednisone and azothiaprine and 2 prednisone and cyclosporine. Platelet uptake index (PUI) was calculated as the ratio of uptake over the T against a reference area. Rejection was diagnosed by biopsy. In groups I and II platelet uptake was seen only in the T patient. In Group III the PUI was 1.54 +- .13 in the rejecting T (n=5), 1.42 +- .2 in the non-rejecting T (n=3), 1.62 in a LRD non-rejecting T and 1.31 (n=2) in C non-rejecting T. In the four patients studied within 5 days of T the PUI was elevated at 1.47 +- .1. The authors conclude that: 1) platelets do not accumulate in normal or nephrotic native kidneys, 2) significant uptake occurs in the first week after C and LRD whether or not rejection is present, and 3) uptake in non-rejecting kidneys cannot be ascribed to perfusion induced endothelial injury since it was present in LRD transplants

Hypokalemic paralysis due to primary hyperaldosteronism simulating gitelman′s syndrome

2009-01-01

Full Text Available Some diseases, such as Gitelman′s syndrome, Bartter′s syndrome, and primary hyperaldosteronism (Conn′s syndrome, may bear some similar clinical and laboratory findings. Their treatment modalities being different from one another, the need for a scrupulous diagnostic evaluation arises as far as clinical practice is concerned. In this report, we present a patient with Conn′s syndrome who was initially considered to have Gitelman′s syndrome due to displaying a few overlapping features of both diseases. We also give an account of the hardships encountered during the diagnostic evaluation.

Adrenocorticotropic hormone (ACTH) has shown efficacy as primary and secondary therapy for nephrotic syndrome due to membranous nephropathy. The data on using ACTH to treat idiopathic FSGS are limited. This report describes our experience using ACTH for nephrotic syndrome due to idiopathic FSGS in the United States. Twenty-four patients with nephrotic syndrome from idiopathic FSGS were treated with ACTH gel at two academic medical centers between 2009 and 2012, either as part of investigator-initiated pilot studies (n=16) or by prescription for treatment-resistant FSGS (n=8). The primary outcome was remission of proteinuria. The median dose of ACTH was 80 units injected subcutaneously twice weekly. Treatment durations were not uniform. Twenty-two patients had received immunosuppression (mean, 2.2 medications) before ACTH therapy. Six patients had steroid-dependent and 15 had steroid-resistant FSGS. At the time of ACTH initiation, the median serum creatinine (interquartile range) was 2.0 (1.1-2.7) mg/dl, estimated GFR was 36 (28-78) ml/min per 1.73 m(2), and urine protein-to-creatinine ratio was 4595 (2200-8020) mg/g. At the end of ACTH therapy, 7 of 24 patients (29%) experienced remission (n=2 complete remissions, n=5 partial remissions). All remitters had steroid-resistant (n=5) or steroid-dependent (n=2) FSGS. Two responders relapsed during the follow-up period (mean ± SD, 70±31 weeks). Adverse events occurred in 21 of 24 patients, including one episode of new-onset diabetes that resolved after stopping ACTH and two episodes of AKI. Response to ACTH treatment among steroid-resistant or steroid-dependent patients with FSGS is low, but ACTH gel may be a viable treatment option for some patients with resistant nephrotic syndrome due to idiopathic FSGS. Further research is necessary to determine which patients will respond to therapy.

[Value of aspiration biopsy of subcutaneous fat in amyloidosis].

Science.gov (United States)

Ponce, P; Carvalho, F; Coelho, A

1986-01-01

Fine-needle aspiration of subcutaneous fat (FNAF) was performed in 24 patients, 12 with previously diagnosed amyloidosis presenting with proteinuria or nephrotic syndrome, and 12 presenting a nephrotic syndrome without amyloidosis on renal biopsy. FNAF was positive in 10 of 12 patients with amyloidosis (sensitivity: 83%) and negative in 12 of 12 patients with non-amyloid nephrotic syndrome (specificity: 100%). Considering a 2.5 to 10% prevalence of amyloidosis in adult patients with proteinuria or nephrotic syndrome, a positive FNAF is diagnostic of amyloidosis, and a negative FNAF rules out the diagnosis with a probability of 98 to 99%. FNAF is a simple and safe method which can be useful in patients who cannot undergo a renal biopsy.

Chronic kidney disease, severe arterial and arteriolar sclerosis and kidney neoplasia: on the spectrum of kidney involvement in MELAS syndrome.

MELAS syndrome (MIM ID#540000), an acronym for Mitochondrial Encephalopathy, Lactic Acidosis and Stroke-like episodes, is a genetically heterogeneous mitochondrial disorder with protean manifestations and occasional kidney involvement. Interest in the latter is rising due to the identification of cases with predominant kidney involvement and to the hypothesis of a link between mitochondrial DNA and kidney neoplasia. We report the case of a 41-year-old male with full blown MELAS syndrome, with lactic acidosis and neurological impairment, affected by the "classic" 3243A > G mutation of mitochondrial DNA, with kidney cancer. After unilateral nephrectomy, he rapidly developed severe kidney functional impairment, with nephrotic proteinuria. Analysis of the kidney tissue at a distance from the two tumor lesions, sampled at the time of nephrectomy was performed in the context of normal blood pressure, recent onset of diabetes and before the appearance of proteinuria. The morphological examination revealed a widespread interstitial fibrosis with dense inflammatory infiltrate and tubular atrophy, mostly with thyroidization pattern. Vascular lesions were prominent: large vessels displayed marked intimal fibrosis and arterioles had hyaline deposits typical of hyaline arteriolosclerosis. These severe vascular lesions explained the different glomerular alterations including ischemic and obsolescent glomeruli, as is commonly observed in the so-called "benign" arteriolonephrosclerosis. Some rare glomeruli showed focal segmental glomerulosclerosis; as the patient subsequently developed nephrotic syndrome, these lesions suggest that silent ischemic changes may result in the development of focal segmental glomerulosclerosis secondary to nephron loss. Nephron loss may trigger glomerular sclerosis, at least in some cases of MELAS-related nephropathy. Thus the incidence of kidney disease in the "survivors" of MELAS syndrome may increase as the support therapy of these patients improves.

An intriguing association of Turner syndrome with severe nephrotic syndrome: searching for a diagnosis.

Minzala, G; Ismail, G

Systemic lupus erythematosus (SLE) is a chronic disease caused by an aberrant autoimmune response, with a large spectrum of clinical manifestations. It strikingly affects women. Recent papers reveal that the men with Klinefelter syndrome (47, XXY) have a higher incidence of lupus than the men in the general population, similar with that of genotypic females. On the other hand, there is a great lack of information regarding the association of SLE with Turner syndrome, but it seems to be a lower risk for females with Turner to develop SLE. We present a rare association of a Turner syndrome with SLE, with negative immunology for SLE and with diagnosis made on renal biopsy. These data suggest that the presence of two X chromosomes may predispose to SLE, the ligand (CD40 ligand) for one of the genes that contributes to the pathogenesis of SLE being located on the X chromosome. © The Author(s) 2016.

Non-synonymous single nucleotide changes (nSNC) are coding variants that introduce amino acid changes in their corresponding proteins. They can affect protein function; they are believed to have the largest impact on human health compared with SNCs in other regions of the genome. Such a sequence alteration directly affects their structural stability through conformational changes. Presence of these conformational changes near catalytic site or active site may alter protein function and as a consequence receptor-ligand complex interactions. The present investigation includes assessment of human podocin mutations (G92C, P118L, R138Q, and D160G) on its structure. Podocin is an important glomerular integral membrane protein thought to play a key role in steroid resistant nephrotic syndrome. Podocin has a hairpin like structure with 383 amino acids, it is an integral protein homologous to stomatin, and acts as a molecular link in a stretch-sensitive system. We modeled 3D structure of podocin by means of Modeller and validated via PROCHECK to get a Ramachandran plot (88.5% in most favored region), main chain, side chain, bad contacts, gauche and pooled standard deviation. Further, a protein engineering tool Triton was used to induce mutagenesis corresponding to four variants G92C, P118L, R138Q and D160G in the wild type. Perusal of energies of wild and mutated type of podocin structures confirmed that mutated structures were thermodynamically more stable than wild type and therefore biological events favored synthesis of mutated forms of podocin than wild type. As a conclusive part, two mutations G92C (-8179.272 kJ/mol) and P118L (-8136.685 kJ/mol) are more stable and probable to take place in podocin structure over wild podocin structure (-8105.622 kJ/mol). Though there is lesser difference in mutated and wild type (approximately, 74 and 35 kJ/mol), it may play a crucial role in deciding why mutations are favored and occur at the genetic level.

A low-protein diet restricts albumin synthesis in nephrotic rats.

High-protein diets increase albumin synthesis in rats with Heymann nephritis but albuminuria increases also, causing serum albumin concentration to be suppressed further than in nephrotic animals eating a low-protein diet. Experiments were designed to determine whether dietary protein augmentation directly stimulates albumin synthesis, or whether instead increased albumin synthesis is triggered by the decrease in serum albumin concentration. Evidence is presented that dietary protein augmenta...

2011-11-01

Full Text Available Orbital apex syndrome is commonly been thought to have a poor prognosis. Many cases of this syndrome have been reported to be caused by paranasal sinus mycosis. We encountered a very rare case (60-year-old woman of sinusitis with orbital apex syndrome due to Pseudomonas aeruginosa infection. She had received insulin and dialysis for diabtes and diabetic nephropathy, moreover anticoagulants after heart by-pass surgery. She underwent endoscopic sinus operation and was treated with antibiotics, but her loss of left vision did not improve. Recently, sinusitis cases due to Pseudomonas aeruginosa were reported to be a increasing. Therefore, we should consider the possibility of Pseudomonas aeruginosa as well as mycosis as infections of the sinus, especially inpatients who are immunocompromised body.

Proteinuria is an established risk factor for progression of renal disease, including diabetic nephropathy. The predictive power of proteinuria, especially nephrotic range proteinuria, for progressive renal deterioration has been well demonstrated in diabetic patients with normal to relatively preserved renal function. However, little is known about the relationship between severity of proteinuria and renal outcome in pre-dialysis diabetic patients with severely impaired renal function. 125 incident dialysis patients with type 2 diabetes were identified. This study was aimed at retrospectively evaluating the impact of nephrotic range proteinuria (urinary protein-creatinine ratio above 3.5 g/gCr) on renal function decline during the 3 months just prior to dialysis initiation. In total, 103 patients (82.4 %) had nephrotic range proteinuria. The median rate of decline in estimated glomerular filtration rate (eGFR) in this study population was 0.98 (interquartile range 0.51-1.46) ml/min/1.73 m(2) per month. Compared to patients without nephrotic range proteinuria, patients with nephrotic range proteinuria showed significantly faster renal function decline (0.46 [0.24-1.25] versus 1.07 [0.64-1.54] ml/min/1.73 m(2) per month; p = 0.007). After adjusting for gender, age, systolic blood pressure, serum albumin, calcium-phosphorus product, hemoglobin A1c, and use of an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker, patients with nephrotic range proteinuria showed a 3.89-fold (95 % CI 1.08-14.5) increased risk for rapid renal function decline defined as a decline in eGFR ≥0.5 ml/min/1.73 m(2) per month. Nephrotic range proteinuria is the predominant renal risk factor in type 2 diabetic patients with severely impaired renal function receiving pre-dialysis care.

Muckle-Wells syndrome is a systemic autoinflammatory disease included in the group of hereditary periodic febrile syndromes. We report the case of a patient with this rare disease to call the attention to the singularity of this condition, its low incidence, its atypical presentation and the subsequent delay in the diagnosis, which is reached when late and devastating consequences have taken place. In this case, the first-line therapy, anti-interleukin 1 (IL-1), failed to control the disease. Nevertheless, the IL-6 inhibitor, tocilizumab, proved effective, achieving the total remission of nephrotic syndrome associated with AA secondary amyloidosis, changing the bleak prognosis of this disease.

Individuals of African ancestry harboring two variant alleles within apolipoprotein L1 ( APOL1 ) are classified with a high-risk (HR) genotype. Adults with an HR genotype have increased risk of focal segmental glomerulosclerosis and chronic kidney disease compared with those with a low-risk (LR) genotype (0 or 1 variants). The role of APOL1 risk genotypes in children with glomerular disease is less well known. This study characterized 104 African-American children with a glomerular disease by APOL1 genotype in two cohorts: the Chronic Kidney Disease in Children (CKiD) and Nephrotic Syndrome Study Network (NEPTUNE). Among these subjects, 46% had an HR genotype with a similar age at cohort enrollment. For APOL1 HR children, the median age of disease onset was older (CKiD: 4.5 versus 11.5 years for LR versus HR; NEPTUNE: 11 versus 14 years for LR versus HR, respectively) and preterm birth was more common [CKiD: 27 versus 4%; NEPTUNE: 26 versus 12%; combined odds ratio 4.6 (95% confidence interval: 1.4, 15.5)]. Within studies, HR children had lower initial estimated glomerular filtration rate (eGFR) (CKiD: 53 versus 69 mL/min/1.73 m 2 ; NEPTUNE: 74 versus 94 mL/min/1.73 m 2 ). Longitudinal eGFR decline was faster among HR children versus LR (CKiD: -18 versus -8% per year; NEPTUNE: -13 versus -3% per year). Children with an HR genotype in CKiD and NEPTUNE seem to have a more aggressive form of glomerular disease, in part due to a higher prevalence of focal segmental glomerulosclerosis. These consistent findings across independent cohorts suggest a common natural history for children with APOL1 -associated glomerular disease. Further study is needed to determine the generalizability of these findings. © The Author 2016. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.

Recombinant 4 syndrome due to an unbalanced pericentric inversion of chromosome 4.

Battaglia, A; Brothman, A R; Carey, J C

2002-09-15

An informative patient with a MCA/MR syndrome consisting of developmental delay, prenatal onset growth delay, microcephaly, distinctive face, iris coloboma, and a congenital heart defect was found, on chromosome analysis, to have the following complement: 46,XY,rec(4) dup(4p) inv(4)(p14q35.1) mat. He has a partial 4p trisomy/distal 4q deletion due to an unbalanced pericentric inversion inherited from his mother. Dup (4p) trisomy was originally described by Wilson et al. [1970: Am J Hum Genet 22:679-690] in a similar case with the same chromosome 4 inversion. To date, at least 85 cases of dup (4p) syndrome have been published, mostly due to unbalanced translocations. Recent articles suggest that the phenotype is hard to recognize clinically due to the lack of specificity of findings. In contrast, 4p trisomy due to an unbalanced pericentric inversion of chromosome 4(p14q35), i.e., the recombinant 4 syndrome observed in our patient, appears to be a discrete entity with relatively consistent features. In total there are four other kindreds described in the literature with this inversion, and the phenotype seems recognizable. Thus, we suggest that recombinant 4 syndrome is a discrete entity among 4p trisomy patients. Copyright 2002 Wiley-Liss, Inc.

Anton's syndrome due to cerebrovascular disease: a case report

Directory of Open Access Journals (Sweden)

Maddula Mohana

2009-09-01

Full Text Available Abstract Introduction Anton's syndrome describes the condition in which patients deny their blindness despite objective evidence of visual loss, and moreover confabulate to support their stance. It is a rare extension of cortical blindness in which, in addition to the injury to the occipital cortex, other cortical centres are also affected, with patients typically behaving as if they were sighted. Case presentation We present a case report of an 83-year-old white woman with cortical blindness as a result of bilateral occipital lobe infarcts. Despite her obvious blindness, illustrated by her walking into objects, the patient expressed denial of visual loss and demonstrated confabulation in her accounts of her surroundings, consistent with a diagnosis of Anton's syndrome. Conclusions A suspicion of cortical blindness and Anton's syndrome should be considered in patients with atypical visual loss and evidence of occipital lobe injury. Cerebrovascular disease is the most common cause of Anton's syndrome, as in our patient. However, any condition that may result in cortical blindness can potentially lead to Anton's syndrome. Recovery of visual function will depend on the underlying aetiology, with cases due to occipital lobe infarction after cerebrovascular events being less likely to result in complete recovery. Management in these circumstances should accordingly focus on secondary prevention and rehabilitation.

Serum and urinary lipoproteins in the human nephrotic syndrome: evidence for renal catabolism of lipoproteins

Energy Technology Data Exchange (ETDEWEB)

Shore, V.G.; Forte, T.; Licht, H.; Lewis, S.B.

1982-03-01

The urinary excretion of lipoproteins and the possibility of catabolic alterations on glomerular filtration were investigated in four nephrotic subjects difering in etiology, serum lipoprotein profile, and 24 hr urinary output of protein and lipids. The apolipoproteins and lipoproteins of urine were compared with those of serum with respect to distribution profile, physical properties, and composition. As expected from molecular sieving effects during glomerular filtration, the urinary HDL were more abundant than the lower density lipoproteins even when the plasma LDL was elevated markedly. Intact apolipoproteins were not found in the concentrated urinary fraction isolated by ultrafiltration between the limits of 10/sup 4/ and 5 x 10/sup 4/ daltons. On the basis of immunoreactivity, gel electrophoresis, and amino acid composition, apolipoproteins B and AI are the major and minor proteins, respectively, of urinary LDL, and apo B is the major protein of the urinary IDL and VLDL. Apolipoproteins AI, AII, CI, CIII, and possibly AIV were isolated from the urinary HDL. As much as 20% of the protein moiety of the urinary HDL appeared to be large apolipoprotien fragments with molecular weights and isoelectric points similar to those of apo CII and apo CIII. The lower density classes of urinary lipoproteins also appeared to have lost apo E and apo C's and to have undergone partial proteolysis.

Prune-Belly Syndrome (PBS) is a rare congenital syndrome characterized by the absence of abdominal muscles, anomalies in the urinary tract, megaureter, cryptorchidism or testicular agenesis, hypertension and worsening chronic kidney disease (CKD). The incidence is estimated between 1 out of 35,000 and 1 out of 50,000 born alive, and it affects males in prevalence (97%). In the present study we describe the case of a 38 year old male patient (followed since May 2011) affected by PBS, CKD, one functional kidney at the scintigraphy, pediatric testicular implants, bladder surgery and correction of pectus excavatum. At the beginning of the observation, renal function was deteriorated, with a creatinine 3.3 mg/dl, GFR calculated at MDRD 23 ml/min, proteinuria in nephrotic range (4 g/day), high blood pressure, anemia and hyperparathyroidism. In the following examinations renal function framework worsened, despite the adoption of a low-protein diet. Due to the functional trend, the patient was prescribed hemodialysis as substitute treatment. In January 2013 a first attempt of artero-venous fistula (AVF) did not succeed, while a new AVF in March 2013 resulted effective. In July hemodialysis was started. In the future, we expect to insert the patient in the Kidney Transplant List (since surgical feasibility has already been positively evaluated). Our case is quite peculiar due to the late beginning of substitute treatment. Further, SPB represents a challenge that, in the absence of a prompt and effective treatment, inevitably it leads to terminal uremia; nevertheless, given a proper treatment, a transplant with good chances of success can be envisaged.

Full Text Available BACKGROUND Although pulmonary tuberculosis is a common disease in India, tuberculosis of right middle lobe is infrequent. Tuberculosis of the right middle lobe leading to chronic collapse is a cause of Right Middle Lobe syndrome. METHODS The patients attended Pulmonary Medicine Outdoor at Era’s Lucknow Medical College, Lucknow from April 2015 to March 2016. The purpose of this study is to describe the clinicoradiological features of patients of middle lobe syndrome due to tuberculosis. All patients presented with cough with or without expectoration, fever, chest pain, haemoptysis and constitutional symptoms like loss of appetite and weight. Chest X-ray PA view revealed ill-defined opacity abutting the right cardiac border. HRCT thorax was done in each case. The diagnosis of tuberculous aetiology was based on (1 History of chronic cough and fever, not responding to antibiotic therapy and constitutional symptoms, (2 A positive tuberculin test using 2 TU of PPD RT 23 and (3 Detection of acid fast bacilli by direct smear or Mycobacterium tuberculosis by polymerase chain reaction in bronchoalveolar lavage. RESULTS Out of 10 patients, 4 (40% were males and 6 (60% were females. The mean ages of the males were 55.8 years and females were 60.8 years and overall mean age was 59 years. Most of the patients were females and belonged to the middle age and old age group. ATT was started in all the patients. CONCLUSIONS Right middle lobe syndrome predominantly affects the older population and the female gender. Although tuberculosis is a common disease in India, Middle Lobe Syndrome is a very rare presentation of the disease. Due to non-specific symptoms and usually normal chest X-ray PA view in Right Middle Lobe Syndrome, we should keep a high index of suspicion to diagnose the condition.

Reversible posterior leukoencephalopathy (LEPR) is a clinical entity that affects radiation usually the white matter of the cerebral hemispheres. It is frequently associated with acute arterial hypertension and immunosuppressive therapy, among other causes. The clinical presentation is varied, with headache, nausea, vomiting, impaired consciousness and abnormal behavior, seizures and visual disturbances, symptoms that often regress. Computed tomography (CT) and magnetic resonance imaging (MRI) images show white matter edema predominantly in posterior regions of the brain. We present a 10 year old boy with leprosy in the course of a nephrotic syndrome secondary to acute diffuse glomerunefritis (GNDA) poststreptococcal. (author) [es

Sequence variants in CRB2 cause a syndrome with greatly elevated maternal serum alpha-fetoprotein and amniotic fluid alpha-fetoprotein levels, cerebral ventriculomegaly and renal findings similar to Finnish congenital nephrosis. All reported patients have been homozygotes or compound heterozygotes for sequence variants in the Crumbs, Drosophila, Homolog of, 2 (CRB2) genes. Variants affecting CRB2 function have also been identified in four families with steroid resistant nephrotic syndrome, but without any other known systemic findings. We ascertained five, previously unreported individuals with biallelic variants in CRB2 that were predicted to affect function. We compiled the clinical features of reported cases and reviewed available literature for cases with features suggestive of CRB2-related syndrome in order to better understand the phenotypic and genotypic manifestations. Phenotypic analyses showed that ventriculomegaly was a common clinical manifestation (9/11 confirmed cases), in contrast to the original reports, in which patients were ascertained due to renal disease. Two children had minor eye findings and one was diagnosed with a B-cell lymphoma. Further genetic analysis identified one family with two affected siblings who were both heterozygous for a variant in NPHS2 predicted to affect function and separate families with sequence variants in NPHS4 and BBS7 in addition to the CRB2 variants. Our report expands the clinical phenotype of CRB2-related syndrome and establishes ventriculomegaly and hydrocephalus as frequent manifestations. We found additional sequence variants in genes involved in kidney development and ciliopathies in patients with CRB2-related syndrome, suggesting that these variants may modify the phenotype.

Cyclosporine induced pain syndrome (CIPS) is a newly diagnosed complication of calcineurine inhibitors, mainly observed in solid organ and hematopoetic transplantations. The present case is a male child with steroid resistant nephrotic syndrome on low therapeutic level cyclosporine treatment. He presented with intractable and debilitating leg pain, with no reported history of previous injury or trauma. The pain was reluctant to antimicrobial and sedative treatment. MRI revealed bone marrow and soft tissue edema in the mid shaft of patient's right leg. Inspite of unusual manifestations, CIPS was suggested and cyclosporine discontinued. However, the pain did not improve and was resistant to calcium blocker. Subsequently, core decompression was performed as an unusual treatment of CIPS, revealing normal bone morphology. The pain improved rapidly and the patient was discharged a few days later.

Full Text Available Objective. To assess whether high-molecular-weight proteins excretion predicts outcome and therapy-responsiveness in patients with FSGS and nephrotic syndrome. Research Design and Methods. Thirty-eight patients measured at biopsy fractional excretion of IgG (FEIgG and urinary α2-macroglobulin/creatinine ratio (α2m/C. Low and high risk groups were defined by cutoffs assessed by ROC analysis. In all patients first-line therapy was with steroids alone or in combination with cyclophosphamide. Results. α2m/C and FEIgG were correlated with segmental sclerosis (r=0.546; r=0.522. Twenty-three patients (61% entered Remission and 9 (24% progressed to ESRD. Comparing low and high risk groups, by univariate analysis remission was predicted by FEIgG (77% versus 25%, P=0.016 and α2m/C (81% versus 17%, P=0.007 and ESRD at best by FEIgG (0% versus 75%, P<0.0001 and α2m/C (4% versus 67%, P<0.0001. By multivariate analysis FEIgG was the only independent predictor of remission and α2m/C the most powerful predictor of ESRD. Low and high risk groups of FEIgG and α2m/C in combination had very high predictive value of sustained remission and ESRD in response to therapy. Conclusions. FEIgG and α2m/C are powerful predictors of outcome and responsiveness to steroids and cyclophosphamide; their predictive value, if validated in prospective studies, may be useful in clinical practice suggesting first-line alternative treatments in high risk patients.

Targeted exome sequencing integrated with clinicopathological information reveals novel and rare mutations in atypical, suspected and unknown cases of Alport syndrome or proteinuria.

Rajshekhar Chatterjee

Full Text Available We applied customized targeted next-generation exome sequencing (NGS to determine if mutations in genes associated with renal malformations, Alport syndrome (AS or nephrotic syndrome are a potential cause of renal abnormalities in patients with equivocal or atypical presentation. We first sequenced 4,041 exons representing 292 kidney disease genes in a Caucasian woman with a history of congenital vesicoureteral reflux (VUR, recurrent urinary tract infections and hydronephrosis who presented with nephrotic range proteinuria at the age of 45. Her biopsy was remarkable for focal segmental glomerulosclerosis (FSGS, a potential complication of longstanding VUR. She had no family history of renal disease. Her proteinuria improved initially, however, several years later she presented with worsening proteinuria and microhematuria. NGS analysis revealed two deleterious COL4A3 mutations, one novel and the other previously reported in AS, and a novel deleterious SALL2 mutation, a gene linked to renal malformations. Pedigree analysis confirmed that COL4A3 mutations were nonallelic and compound heterozygous. The genomic results in conjunction with subsequent abnormal electron microscopy, Collagen IV minor chain immunohistochemistry and progressive sensorineural hearing loss confirmed AS. We then modified our NGS approach to enable more efficient discovery of variants associated with AS or a subset of FSGS by multiplexing targeted exome sequencing of 19 genes associated with AS or FSGS in 14 patients. Using this approach, we found novel or known COL4A3 or COL4A5 mutations in a subset of patients with clinically diagnosed or suspected AS, APOL1 variants associated with FSGS in African Americans and novel mutations in genes associated with nephrotic syndrome. These studies demonstrate the successful application of targeted capture-based exome sequencing to simultaneously evaluate genetic variations in many genes in patients with complex renal phenotypes and

Full Text Available Acquired von Willebrand syndrome (AVWS is an uncommon, underdiagnosed, and heterogeneous disease which is increasingly recognized as a cause of bleeding diatheses. Systemic lupus erythematosus (SLE is an infrequent cause of AVWS. Herein, we report a case of AVWS diagnosed during the initial presentation of SLE in a previously healthy young man with no family history of bleeding diathesis who presented with worsening epistaxis, gastrointestinal bleeding, and anasarca. He was found to have severe anemia and prolonged activated partial thromboplastin time (aPTT with severely decreased levels of von Willebrand factor (VWF measurements in addition to markedly decreased factor VIII levels. Further evaluation revealed nephrotic syndrome and interstitial lung disease due to SLE. He initially received combination therapy with intravenous immunoglobulin (IVIG and von Willebrand factor/factor VIII concentrates without significant improvement. Treatment with steroids, cyclophosphamide, and rituximab was followed by clinical improvement evidenced by cessation of bleeding. The short follow-up did not allow us to definitely prove the therapeutic effect of immunosuppressive treatment on AVWS in SLE patients. This case adds to the literature supporting the relationship between AVWS and SLE and highlights the importance of combination therapy in the treatment of severe AVWS as well as the role of IVIG, cyclophosphamide, and rituximab in AVWS associated with SLE.

Summary Background: Sjögren syndrome (SS) is an autoimmune-lymphoproliferative disorder characterized by mononuclear cell infiltration of exocrine glands. Clinically, Sjögren syndrome (SS) has a wide spectrum, varying from autoimmune exocrinopathy to systemic involvement. There have been few cases reporting that primary SS developed with distal renal tubular acidosis clinically. Case Report: Here, we present a case with primary Sjögren syndrome accompanied by hypopotassemic paralysis due to renal tubular acidosis. Severe hypopotassemia, hyperchloremic metabolic acidosis, alkaline urine and disorder in urinary acidification test were observed in the biochemical examination of the 16-year-old female patient, who had applied to our clinic for extreme loss of muscle force. After the examinations it was determined that the patient had developed Type 1 RTA (distal RTA) due to primary Sjögren syndrome. Potassium and alkaline replacement was made and an immediate total recovery was achieved. Conclusions: Hypopotassemic paralysis due to primary Sjögren syndrome is a rare but severe disorder that could lead to death if not detected early and cured appropriately. Thus, effective treatment should be immediately initiated in cases where severe hypopotassemia is accompanied by metabolic acidosis, and the cases should also be examined for extraglandular involvement of SS.

Full Text Available Cushing syndrome is rare in infancy and usually due to an adrenocortical tumor (ACT. We report an infant with Cushing syndrome due to adrenocortical carcinoma. The patient presented at six months of age with a three-month history of growth failure, rapid weight gain, acne, and irritability. Physical examination showed obesity, hypertension, and Cushingoid features. Biochemical evaluation showed very high serum cortisol, mildly elevated testosterone, and suppressed ACTH. Abdominal MRI revealed a heterogeneous right adrenal mass extending into the inferior vena cava. Evaluation for metastases was negative. The tumor was removed surgically en bloc. Pathologic examination demonstrated low mitotic rate, but capsular and vascular invasion. She received no adjuvant therapy. Her linear growth has improved and Cushingoid features resolved. Hormonal markers and quarterly PET scans have been negative for recurrence 24 months postoperatively. In conclusion, adrenocortical neoplasms in children are rare, but should be considered in the differential diagnosis of Cushing syndrome.

Full Text Available Background. Shock syndrome is an acute tissue hypoperfusion. Early diagnosis and adequate symptomatic and causal treatment are mandatory. In spite of different etiologies (dehidration, bleeding, heart failure, sepsis, clinical signs and symptomes are similar (hypotension, tachicardia, tachipnoe, pallor, cold and wet skin, oliguria and metabolic acidosis. Rarely, the shock syndrome is the consequence of the adrenal insufficiency due to hypopituitarism caused by brain tumor where early treatment with hydrocortisone is urgent.Methods. This article presents a patient with a shock syndrome and multiorgan failure. Endocrinological testing and brain CT demonstrated an endocrinologically inactive tumor of hypophysis. The tumor was growing into adjacent hypophyseal tissue and causing hypopituitarism with secondary hypothyroidism and adrenal insufficiency and deficit of both gonadotropins and growth hormone.Conclusions. Primary or secondary adrenal insufficiency are among rare causes of shock syndrome. Whenever it is suspected, estimation of serum levels of cortisol and ACTH is necessary and immediate treatment with hydrocortisone should be instituted.

Dhillon, N; Högler, W

2011-06-01

Sodium valproate (VPA) is commonly used to treat epilepsy in children. Renal dysfunction is a rare side eff ect but can present as tubulopathy such as Fanconi syndrome. We report on an 8-year-old disabled girl with myoclonic epilepsy who was referred for investigation of recurrent low impact fractures of the distal femur which were initially thought to be caused by her severe immobility. However, she was subsequently found to have hypophosphataemia secondary to Fanconi syndrome due to prolonged VPA use. After VPA withdrawal renal function and serum phosphate levels normalised and X-rays improved dramatically. The possibility of drug-induced osteoporosis and fractures should always be considered in disabled children, even in the presence of severe immobility.

Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma

Directory of Open Access Journals (Sweden)

Avradip Santra

2016-07-01

Full Text Available Superior vena cava (SVC syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e.g., malignancy. Here, an unusual case of sudden onset SVC syndrome has been reported, which on initial radiologic evaluation was found to have a lung nodule without any significant mediastinal mass or adenopathy compressing SVC. Subsequent investigation with Doppler ultrasonography of the neck showed thrombosis in the right internal jugular, right subclavian and right brachiocephalic vein, which was responsible for SVC syndrome. Histopathological evaluation of lung nodule confirmed presence of an adenocarcinoma. Therefore, venous thromboembolism as a paraneoplastic syndrome should be kept in mind while evaluating a case of SVC obstruction in a cancer patient. Management of the underlying disease is of prime importance in such cases and anticoagulation is the mainstay of therapy. Ability to identify paraneoplastic syndrome may have a significant effect on clinical outcome, ranging from early diagnosis to improved quality of life of the patient.

Retrospective mutational analysis of NPHS1, NPHS2, WT1 and LAMB2 in children with steroid-resistant focal segmental glomerulosclerosis – a single-centre experience

Full Text Available The aim of our study was to examine NPHS1, NPHS2, WT1 and LAMB2 mutations, previously reported in two thirds of patients with nephrotic syndrome with onset before the age of one year old. Genomic DNA samples from Polish children (n=33 with Steroid-ResistantNephrotic Syndrome (SRNS due to focal segmental glomerulosclerosis (FSGS, manifesting before the age of 13 years old, underwent retrospective analysis of NPHS1, NPHS2, WT1 (exons 8, 9 and adjacent exon/intron boundaries and LAMB2. No pathogenic NPHS1 or LAMB2 mutations were found in our FSGS cohort. SRNS-causing mutations of NPHS2 and WT1 were detected in 7 of 33 patients (21%, including those with nephrotic syndrome manifesting before one year old: five of seven patients. Four patients had homozygous c.413G>A (p.Arg138Gln NPHS2 mutations; one subject was homozygous for c.868G>A (p.Val290Met NPHS2. A phenotypic female had C>T transition at position +4 of the WT1 intron 9 (c.1432+4C>T splice-donor site, and another phenotypic female was heterozygous for G>A transition at position +5 (c.1432+5G>A. Genotyping revealed a female genotypic gender (46, XX for the first subject and male (46, XY for the latter. In addition, one patient was heterozygous for c.104dup (p.Arg36Profs*34 NPHS2; two patients carried a c.686G>A (p.Arg229Gln NPHS2 non-neutral variant. Results indicate possible clustering of causative NPHS2 mutations in FSGS-proven SRNS with onset before age one year old, and provide additional evidence that patients with childhood steroid-resistant nephrotic syndrome due to focal segmentalglomerulosclerosis should first undergo analysis of NPHS2 coding sequence and WT1 exons 8 and 9 and surrounding exon/intron boundary sequences, followed by gender genotyping.

Podocyte dysfunction impairs the size selectivity of the glomerular filter, leading to proteinuria, hypoalbuminuria, and edema, clinically defined as nephrotic syndrome. Hereditary forms of nephrotic syndrome are linked to mutations in podocyte-specific genes. To identify genes contributing to podocyte dysfunction in acquired nephrotic syndrome, we studied human glomerular gene expression data sets for glomerular-enriched gene transcripts differentially regulated between pretransplant biopsy samples and biopsies from patients with nephrotic syndrome. Candidate genes were screened by in situ hybridization for expression in the zebrafish pronephros, an easy-to-use in vivo assay system to assess podocyte function. One glomerulus-enriched product was the Rho-GTPase binding protein, IQGAP2. Immunohistochemistry found a strong presence of IQGAP2 in normal human and zebrafish podocytes. In zebrafish larvae, morpholino-based knockdown of iqgap2 caused a mild foot process effacement of zebrafish podocytes and a cystic dilation of the urinary space of Bowman's capsule upon onset of urinary filtration. Moreover, the glomerulus of zebrafish morphants showed a glomerular permeability for injected high-molecular-weight dextrans, indicating an impaired size selectivity of the glomerular filter. Thus, IQGAP2 is a Rho-GTPase binding protein, highly abundant in human and zebrafish podocytes, which controls normal podocyte structure and function as evidenced in the zebrafish pronephros.

Full Text Available Purpose: Midline structural defects in the neural axis can give rise to neuro-ophthalmic symptoms. We report a rare case of keyhole aqueduct syndrome presenting after two years of severe cough due to gastroesophageal reflux disease. Observations: A 58-year-old woman with a 2-year history of daily, severe cough presented to the neuro-ophthalmology clinic with progressive diplopia and oscillopsia. Examination revealed a 1–2 Hz down-beating nystagmus in primary gaze that worsened with left, right, and down gazes. Gaze evoked nystagmus and mild paresis were also seen with up gaze. There was an incomitant left hypertropia due to skew deviation that worsened with right and up gazes and improved with down gaze. She also had a right-sided ptosis and a 3 mm anisocoria not due to cranial nerve 3 paresis or Horner's syndrome. Brain magnetic resonance imaging showed a 1.5 mm × 11.7 mm × 6 mm midline cleft in the ventral midbrain communicating with the cerebral aqueduct, consistent with keyhole aqueduct syndrome. Her nystagmus and diplopia improved with oral acetazolamide treatment, at high doses of 2500–3000 mg per day. Conclusions and importance: We report the first case of midbrain keyhole aqueduct syndrome with ocular motor and other neuro-ophthalmic manifestations associated with severe cough. Although her cough was effectively treated and intracranial pressure measurement was normal, her ophthalmic symptoms continued to progress, which is common in previous cases reported. Treatment with acetazolamide led to significant improvement, supporting the use of acetazolamide in this rare condition.

67 Ga citrate scan has been requested for detection or follow-up of inflammatory or neoplastic disease. Visualization of 67 Ga citrate in the kidneys at 48 and 72 hr post injection is usually interpreted as evidence of renal pathology. But precise mechanisms of abnormal 67 Ga uptake in kidneys were unknown. We undertook a study to determine the clinical value of 67 Ga citrate imaging of the kidneys in 68 patients with primary or secondary nephropathy confirmed by renal biopsy and 66 control patients without renal disease. Renal uptake in 48 to 72 hr images was graded as follows: Grade 0=background activity;1=faint uptake greater than background; 2=definite uptake, but less than lumbar vertebrae;3 same uptake as lumbar vertebrae, but less than liver; 4=same or higher uptake than liver. The results were as follows. 1) 42 of 68(62%) patients with noninfectious nephritis showed grade 2 or higher 67 Ga renal uptake but only 10 percent of control patients showed similar uptake. 2) In 14 patients with systemic lupus erythematosus, 8 of 9 (89%) patients with lupus nephritis exhibited marked renal uptake. 3) 36 of 41 patients (88%) with combined nephrotic syndrome showed Grade 2 or higher renal uptake. 4) Renal 67 Ga uptake was correlated with clinical severity of nephrotic syndrome determined by serum albumin level, 24 hr urine protein excretion and serum lipid levels. 5) After complete remission of nephrotic syndrome, renal uptake in all 8 patients who were initially Grade 3 or 4, decreased to Grade 1 or 0. In conclusion, we think that the mechanism of renal 67 Ga uptake in nephrotic syndrome might be related to the pathogenesis of nephrotic syndrome. In systemic lupus erythematosus, 67 Ga citrate scan is useful in predicting renal involvement.

Renal uptake in 48 to 72 hr images was graded as follows: Grade 0=background activity;1=faint uptake greater than background; 2=definite uptake, but less than lumbar vertebrae;3 same uptake as lumbar vertebrae, but less than liver; 4=same or higher uptake than liver. The results were as follows. 1) 42 of 68(62%) patients with noninfectious nephritis showed grade 2 or higher {sup 67}Ga renal uptake but only 10 percent of control patients showed similar uptake. 2) In 14 patients with systemic lupus erythematosus, 8 of 9 (89%) patients with lupus nephritis exhibited marked renal uptake. 3) 36 of 41 patients (88%) with combined nephrotic syndrome showed Grade 2 or higher renal uptake. 4) Renal {sup 67}Ga uptake was correlated with clinical severity of nephrotic syndrome determined by serum albumin level, 24 hr urine protein excretion and serum lipid levels. 5) After complete remission of nephrotic syndrome, renal uptake in all 8 patients who were initially Grade 3 or 4, decreased to Grade 1 or 0. In conclusion, we think that the mechanism of renal {sup 67}Ga uptake in nephrotic syndrome might be related to the pathogenesis of nephrotic syndrome. In systemic lupus erythematosus, {sup 67}Ga citrate scan is useful in predicting renal involvement.

Full Text Available Systemic onset juvenile idiopathic arthritis (SOJIA can be associated with proteinuria due to various renal pathologies. We report two pediatric cases with SOJIA and nephrotic syndrome secondary to renal amyloidosis, a very rare complication in children. Once present, amyloidosis heralds a poor prognosis for the patient, though early detection may allow some improvement if the inflammatory arthritis is controlled.

Midline structural defects in the neural axis can give rise to neuro-ophthalmic symptoms. We report a rare case of keyhole aqueduct syndrome presenting after two years of severe cough due to gastroesophageal reflux disease. A 58-year-old woman with a 2-year history of daily, severe cough presented to the neuro-ophthalmology clinic with progressive diplopia and oscillopsia. Examination revealed a 1-2 Hz down-beating nystagmus in primary gaze that worsened with left, right, and down gazes. Gaze evoked nystagmus and mild paresis were also seen with up gaze. There was an incomitant left hypertropia due to skew deviation that worsened with right and up gazes and improved with down gaze. She also had a right-sided ptosis and a 3 mm anisocoria not due to cranial nerve 3 paresis or Horner's syndrome. Brain magnetic resonance imaging showed a 1.5 mm × 11.7 mm × 6 mm midline cleft in the ventral midbrain communicating with the cerebral aqueduct, consistent with keyhole aqueduct syndrome. Her nystagmus and diplopia improved with oral acetazolamide treatment, at high doses of 2500-3000 mg per day. We report the first case of midbrain keyhole aqueduct syndrome with ocular motor and other neuro-ophthalmic manifestations associated with severe cough. Although her cough was effectively treated and intracranial pressure measurement was normal, her ophthalmic symptoms continued to progress, which is common in previous cases reported. Treatment with acetazolamide led to significant improvement, supporting the use of acetazolamide in this rare condition.

Iliac Vein Compression Syndrome due to Bladder Distention Caused by Urethral Calculi

Full Text Available We report a rare case of iliac vein compression syndrome caused by urethral calculus. A 71-year-old man had a history of urethral stenosis. He complained of bilateral leg edema and dysuria for 1 week. Physical examination revealed bilateral distention of the superficial epigastric veins, so obstruction of both common iliac veins or the inferior vena cava was suspected. Plain abdominal computed tomography showed a calculus in the pendulous urethra, distention of the bladder (as well as the right renal pelvis and ureter, and compression of the bilateral common iliac veins by the distended bladder. Iliac vein compression syndrome was diagnosed. Bilateral iliac vein compression due to bladder distention (secondary to neurogenic bladder, benign prostatic hyperplasia, or urethral calculus as in this case is an infrequent cause of acute bilateral leg edema. Detecting distention of the superficial epigastric veins provides a clue for diagnosis of this syndrome.

2018-02-01

Hypocomplementemic urticarial vasculitis syndrome (HUVS) is a rare autoimmune disease characterized by multiple organ system involvement, including renal disease, with low complement levels. We report the case of a 31-year-old woman who presented with nonspecific symptoms including fatigue, diarrhea, macular rash and abdominal pain with acute renal failure leading to end-stage kidney disease. Laboratory results showed hematuria, nephrotic range proteinuria, worsening creatinine and low C1q levels. Left kidney biopsy showed proliferative glomerulonephritis with crescent formation. She was treated with 6 months of intravenous cyclophosphamide, followed by 2 doses of intravenous rituximab (1g each), thereafter maintained on mycophenolate mofetil and glucocorticoid-based therapy. She experienced a full recovery of renal function after 12 months of dialysis dependence. Hypocomplementemic urticarial vasculitis syndrome with crescentic glomerulonephritis is a rare disease with only 5 other reported cases in literature. In our case, we document a delayed but excellent renal recovery during a 2-year follow-up. Copyright © 2018 Southern Society for Clinical Investigation. Published by Elsevier Inc.

1. Sodium retention in disease states characterized by proteinuria, such as nephrotic syndrome, preeclampsia, and diabetic nephropathy, occurs through poorly understood mechanism(s). 2. In the nephrotic syndrome, data from experimental and clinical studies indicate that the sodium retention...... originates in the renal cortical collecting duct and involves hyper-activity of the epithelial sodium channel (ENaC). 3. The stimulus for the increased ENaC activity does not appear to involve any of the classical sodium retaining mechanisms, such as the renin-angiotensin-aldosterone system, arginine...... and diabetic nephropathy, which are also characterized by proteinuria and sodium retention. 7. In this review, we will examine the evidence for a role of urinary serine protease activity in the development of sodium and water retention in diseases characterised by proteinuria with a focus on the nephrotic...

2015-08-01

Renal vein thrombosis (RVT) is an uncommon condition in adults and may be caused by endothelial damage, stasis, or hypercoagulable states. RVT is commonly identified in patients with nephrotic syndrome or malignancy. We present the case of a 57-yearold man with no past medical history who presented with a 1-month history of abdominal pain, dysuria, and hematuria. Initial laboratory studies were consistent with acute kidney injury (AKI). Imaging revealed bladder distension, enlargement of the prostate, bilateral hydronephrosis, and left renal vein thrombosis extending into the inferior vena cava. His renal failure and presenting symptoms resolved with placement of a Foley catheter and ureteral stent. The patient was discharged on anticoagulation. Here, we report a rare case of RVT that appears to have occurred as a consequence of obstructive uropathy causing massive bladder distention resulting in compression of the renal vein.

Little is known regarding the association of primary antiphospholipid syndrome (APLS) and proliferative glomerulonephiritis (GN). We describe a biopsy-documented case with primary APLS and proliferative (GN) with no evidence of thrombotic microangiopathy (TMA), and in the absence of other manifestations of systematic lupus erythematosus (SLE). She presented initially with left popliteal deep venous thrombosis and nephrotic syndrome. Her first pregnancy at the age of 26 years resulted in the intra-uterine fetal death at term. Two subsequent pregnancies ended up with miscarriages at 3 and 4 months of gestation. Urinalysis revealed glomerular red blood cells of 1.0000.000/ml and granular cast; proteinuria of 13.4grams/24 hours, which was non-selective; hemoglobin 12 gm/dl, normal white blood cell and platelets; serum albumin 2.6gm/dl; anti-nuclear antibody (ANA) and anti DNA were negative and complement levels normal. Lupus anticoagulant was positive leading to a diagnosis of primary APLS. The biopsy findings were consistent with membranoproliferative GN. She continued to have steroid-resistant proteinuria, but stable renal function after a 12-year follow up period. She had 2 pregnancies during this period and was delivered at term using caesarian section. She received heparin during the pregnancies. Later she developed hypertension easily controlled by atenolol. This case provides evidence that primary APLS can be associated with proliferative GN due to immune deposits and not only TMA as previously reported, and in the complete absence of SLE. Performing more renal biopsies in this group of patients may disclose a greater prevalence of proleferative GN and may help in devising a rationale for treatment. (author)

International Nuclear Information System (INIS)

Fawad, S.

2010-01-01

Background: Recurrent pregnancy loss is a major health problem effecting 1 to 2% of women of reproductive age. Its causes range from chromosomal abnormalities to endocrinological factors and thrombophilia related factors. Treating thrombophilia s especially anti phospholipid syndrome with low dose aspirin and low molecular weight heparin improves foetal outcome. This study will add local data to already existing knowledge. Method: Sixty selected patients from gynaecology OPD of Aero Hospital with clinical and/or serological findings of anti phospholipid syndrome from February 2009 to January 2011 were given aspirin 75 mg once daily and enoxaparine 40 mg subcutaneously once daily from 6 - 8 weeks to 35 and 37 weeks respectively. Results : Ninety-three percent of patients achieved live birth. Out of these 75% patients delivered at term and 18% had preterm delivered. Four (7%) had early pregnancy loss and only one had early neonatal death due to extreme prematurity. None of patients experienced any major hemorrhagic complications . Conclusion: Use of low dose aspirin and low molecular weight heparin is safe in pregnancy and improve foetal outcome in patients with recurrent pregnancy loss due to anti phospholipids syndrome.

Adenocorticotropic hormone (ACTH)-dependent Cushing's syndrome in infancy is extremely rare. We describe the case of a sacro-coccygeal ectopic ACTH-secreting immature teratoma in an infant who also presented the triad of defects characteristic of Currarino syndrome. A girl was born with a large immature teratoma in the sacro-coccygeal region associated with anal atresia. At the age of 7 days, the concentration of α-fetoprotein (AFP) was above the age-specific normal range. Two non-radical surgical excisions of the tumour were performed. At the age of 7 months, she developed polyphagia, acne, hirsutism, hypertension and hypokalemia with elevated ACTH and absence of serum cortisol circadian rhythm. Immunostaining of tumour tissue showed ACTH-immunoreactive cells. Due to unsuccessful therapy with ketoconazole and resistance to antihypertensive medications [blood pressure (BP) 210/160 mmHg], metyrapone was administered, which controlled her ACTH and cortisol levels in the normal range. Following further removal of tumour bulk after three operations during the first year of life, there was a decrease of BP to normal values. A rare case of ectopic ACTH syndrome causing Cushing's syndrome in infancy in the context of Currarino syndrome is reported. Radical surgery has resulted in excision of the tumour and current control of Cushing's syndrome.

Full Text Available Acute post-streptococcal glomerulonephritis (APSGN is very rare below the age of two years. We report a 14-month-old girl who presented with frank hematuria and nephrotic syndrome following group A streptococcal pharyngitis (GAS, which was confirmed by laboratory investigations. The patient underwent a renal biopsy to confirm the diagnosis and was treated with prednisolone. The proteinuria and hematuria resolved completely in eight weeks. Our case demonstrates that APSGN should be considered in evaluating hematuria and nephrotic syndrome in infants and children below two years of age.

Mechanisms of renal NaCl retention in proteinuric disease

In diseases with proteinuria, for example nephrotic syndrome and pre-eclampsia, there often are suppression of plasma renin-angiotensin-aldosterone system components, expansion of extracellular volume and avid renal sodium retention. Mechanisms of sodium retention in proteinuria are reviewed...... of proteolytic activation of ENaC has been explored. Proteolysis leads to putative release of an inhibitory peptide from the extracellular domain of the gamma ENaC subunit. This leads to full activation of the channel.

To report a case of Cushing syndrome due to apparently sporadic primary pigmented nodular adrenal disease in a young woman. We describe the clinical, biochemical, radiologic, and histologic findings of Cushing syndrome due to the rare condition of primary pigmented nodular adrenal disease. A 30-year-old woman presented with a 2-year history of worsening itch without rash over her shoulders and arms and weight gain, particularly around the abdomen and face. Careful questioning did not elicit any history of exogenous glucocorticoid use (systemic or topical), including hydrocortisone. On examination, the patient had a slightly rounded and plethoric face, a small buffalo hump, central adiposity, and thin skin with a few small striae on her inner thighs. No features of the Carney complex were observed. Investigations showed hypercortisolism with suppressed corticotropin and normal adrenal imaging despite documentation of enlarged adrenal glands at removal. High-dose dexamethasone administration was followed by a decrease in urinary free cortisol excretion rather than a paradoxical rise as previously reported in primary pigmented nodular adrenal disease. No mutations were detected in the PRKAR1A gene. Primary pigmented nodular adrenal disease should be suspected in patients with corticotropin-independent Cushing syndrome who have normal adrenal imaging. The role of genetic testing in apparently sporadic cases is not established, but cumulative experience may be helpful in defining the frequency of PRKAR1A mutations.

To examine the efficacy of two vitamin D dosages (1000 vs. 400 IU/day) for osteoprotection in children with new-onset and infrequently-relapsing nephrotic syndrome (IFRNS) receiving corticosteroids. This parallel-group, open label, randomised clinical trial enrolled 92 children with new-onset nephrotic syndrome (NS) (n = 28) or IFRNS (n = 64) to receive 1000 IU/day (Group A, n = 46) or 400 IU/day (Group B, n = 46) vitamin D (administered as a single bolus initial supplemental dose) by block randomisation in a 1:1 allocation ratio. In Group A, vitamin D (cholecalciferol in a Calcirol® sachet) was administered in a single stat dose of 84,000 IU on Day 1 of steroid therapy (for new-onset NS), calculated for a period of 12 weeks@1000 IU/day) and 42,000 IU on Day 1 of steroid therapy (for IFRNS, calculated for a period of 6 weeks@1000 IU/day). In Group B, vitamin D (cholecalciferol in a Calcirol® sachet) was administered as a single stat dose of 33,600 IU on Day 1 of steroid therapy (for new-onset NS, calculated for a period of 12 weeks@400 IU/day) and 16,800 IU on Day 1 of steroid therapy (for IFRNS, calculated for a period of 6 weeks@400 IU/day). The proportionate change in bone mineral content (BMC) was analysed in both groups after vitamin D supplementation. Of the 92 children enrolled, 84 (n = 42 new onset, n = 42 IFRNS) completed the study and were included in the final analysis. Baseline characteristics including initial BMC, bone mineral density, cumulative prednisolone dosage and serum 25-hydroxycholecalciferol levels were comparable in the two groups. There was a greater median proportionate change in BMC in the children who received 1000 IU/day vitamin D (3.25%, IQR -1.2 to 12.4) than in those who received 400 IU/day vitamin D (1.2%, IQR -2.5 to 3.8, p = 0.048). The difference in proportionate change in BMC was only statistically significant in the combined new-onset and IFRNS, but not for IFRNS alone. There was a greater

Early diagnosis of minimal change disease (MCD) is challenging in nephrotic children. CD80 is a protein expressed on the surface of podocytes associated with nephrotic syndrome and it is implicated in the induction of proteinuria. This study aimed to investigate the use of urinary CD80 for the diagnosis of MCD. Urinary CD80 levels were evaluated in 36 children with nephrotic syndrome and normal glomerular filtration rate. They were divided into three groups of MCD (n = 21), focal segmental glomerulosclerosis (n = 9), and other glomerulopathies (n = 6). The MCD group was subdivided into 2 of those with remission (n = 11) and those in the active stage (n = 10). Forty healthy children were included as controls. The urinary CD80 level was significantly higher in the MCD group (3.5 ± 2.1 ng/mg creatinine) than in the focal segmental glomerulosclerosis group (1.2 ± 0.5 ng/mg creatinine, P MCD groups. There was no significant difference between MCD in remission and MCD in relapse, either. A urinary CD80 cutoff value of 1.5 ng/gm creatinine showed a sensitivity of 100% and a specificity of 86% for diagnosis of MCD. Urinary CD80 levels were significantly higher in the children with MCD than in the controls and patients with other causes of nephrotic syndrome.

2017-01-01

Full Text Available A 32-year-old male presented with acute and severe nephrotic syndrome as well as massive right cervical lymphadenopathy for <2 years. Computed tomography scan of the chest, abdomen, and pelvis did not reveal any lymphadenopathy. Histopathology and immunohistochemical testing of his lymph node biopsy showed infiltrate enriched with immunoglobulin G4 (IgG4-positive plasma cells. His kidney biopsy showed granular membranous deposits of IgG4 in the basement membrane without interstitial infiltrate. Antiphospholipid 2 receptor antibodies were absent excluding its "idiopathic" nature. Since he was allergic to rituximab, he was treated with corticosteroids for two months and a combination of tacrolimus and mycophenolate. His lymphadenopathy disappeared, and his proteinuria abated. The dose of the latter two medications was reduced to half after four months and will be maintained for a minimum of two years to prevent relapse of his disease.

2017-01-01

Cushing's syndrome due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions has occasionally been described. We retrospectively reviewed all 164 cases of Cushing's syndrome and 77 cases of pheochromocytomas during 10 years. Of all cases with Cushing's syndrome, only two cases (1.2 %) were due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions (one case of pheochromocytoma and one case of adrenal medullary hyperplasia). Of all pheochromocytomas only the above-mentioned case (1.3 %) also gave rise to an ectopic adrenocorticotropic hormone syndrome. The clinical presentation of adrenocorticotropic hormone-secreting pheochromocytoma and adrenal medullary hyperplasia can be anything from mild to dramatic. These are rare conditions important to bear in mind in the workup of a patient with Cushing's syndrome or with pheochromocytoma. The identification of ectopic adrenocorticotropic hormone secretion from adrenal medullary lesions can be life-saving.

Patients with resection of stomach and especially with Billroth II reconstruction (gastro jejunal anastomosis), are more likely to develop afferent loop syndrome which is a rare complication. When the afferent part is obstructed, biliary and pancreatic secretions accumulate and cause the distention of this part. In the case of a complete obstruction (rare), there is a high risk developing necrosis and perforation. This complication has been reported once in the literature. A 54-year-old Greek male had undergone a pancreato-duodenectomy (Whipple procedure) one year earlier due to a pancreatic adenocarcinoma. Approximately 10 months after the initial operation, the patient started having episodes of cholangitis (fever, jaundice) and abdominal pain. This condition progressively worsened and the suspicion of local recurrence or stenosis of the biliary-jejunal anastomosis was discussed. A few days before his admission the patient developed signs of septic cholangitis. Our case demonstrates a rare complication with serious clinical manifestation of the afferent loop syndrome. This advanced form of afferent loop syndrome led to the development of huge enterobiliary reflux, which had a serious clinical manifestation as cholangitis and systemic sepsis, due to bacterial overgrowth, which usually present in the afferent loop. The diagnosis is difficult and the interventional radiology gives all the details to support the therapeutic decision making. A variety of factors can contribute to its development including adhesions, kinking and angulation of the loop, stenosis of gastro-jejunal anastomosis and internal herniation. In order to decompress the afferent loop dilatation due to adhesions, a lateral-lateral jejunal anastomosis was performed between the afferent loop and a small bowel loop.

Short stature represents one of the main features of children with Noonan syndrome. The reason for impaired growth remains largely unknown. To assess GH and IGF1 secretion in children with Noonan syndrome. 12 prepubertal children with Noonan syndrome due to mutations in the PTPN11 gene [7 males, 6 females; median age, years: 8.6 (range 5.1-13.4)] were studied; 12 prepubertal children with short stature (SS) [7 males, 5 females; median age, years: 8.1 (range 4.8-13.1)] served as the control group. GH secretion after arginine stimulation test; IGF1 generation test by measurement of IGF1 levels before and after recombinant GH (rGH) administration (0.05 mg/kg/day for 4 days). Baseline and stimulated peak values of GH were not significantly different between the two groups. At +120 minutes, GH levels remained significantly higher (p = 0.0121) in comparison with baseline values in children with Noonan syndrome. Baseline IGFI levels in patients and in SS controls were not significantly different, in contrast to values after the rGH generation test [205 ng/mL (interquartiles 138.2-252.5 ng/mL) and 284.5 ng/mL (interquartiles 172-476 ng/mL), respectively; p = 0.0248]. IGF1 values were significantly related to height (baseline: r = 773, p = 0.0320; peak: r = 0.591, p = 0.0428) in children with Noonan syndrome. Blunted increase of IGF1 after the rGH generation test was present in children with Noonan syndrome due to mutations in the PTPN11 gene in comparison with SS children. This finding may be due to partial GH resistance in the former likely related to altered Ras-MAPK signaling pathway.

Chylous ascites and lymphangiectasia in focal segmental glomerulosclerosis--a rare coexistence: a case report.

Nephrotic syndrome is considered a rare cause of chylous ascites. Intestinal lymphangiectasia in a background of chylous ascites and without any lymphatic obstruction has been reported in association with yellow nail syndrome, which is a rare clinical occurrence in itself. The existence of chylous ascites, duodenal and splenic lymphangiectasia (without any lymphatic obstruction) and nephrotic syndrome in the form of focal segmental glomerulosclerosis in the same patient makes this case the first of its kind to be reported in the literature. Here we report the case of a 54-year-old Asian man who presented with recurrent episodes of anasarca for approximately 25 years. He was subsequently found to have chylous ascites, lymphangiectasia and persistent proteinuria. A renal biopsy revealed focal segmental glomerulosclerosis, not otherwise specified. A lymphangiogram, which was performed with the purpose of addressing the intestinal lymphangiectasia, failed to demonstrate any abnormality of lymphatic channels. He was put on oral steroids with consequent remission of his oedema and proteinuria. This case highlights the fact that duodenal and splenic lymphangiectasia can exist in a scenario of chylous ascites without any obvious obstruction of lymphatic channels and in the absence of yellow nail syndrome. This case also signifies that chylous ascites may be a rare presenting feature of nephrotic syndrome and hence this aspect should be considered while in diagnostic dilemma regarding such a clinical presentation.

Full Text Available A 35-year-old male patient was admitted with fatigue and muscle weakness. He had been on methimazole due to thyrotoxicosis for 2 weeks. Laboratory tests showed overt hyperthyroidism and hypokalemia. Potassium replacement was started with an initial diagnosis of thyrotoxic hypokalemic periodic paralysis. Later on, despite the euthyroid condition and potassium chloride treatment, hypokalemia persisted. Further investigations revealed hyperreninemic hyperaldosteronism. The patient was considered to have Gitelman′s syndrome (GS and all genetic analysis was done. A c. 1145C>T, p.Thr382Met homozygote missense mutation located on solute carrier family 12, member gene 3, exon 9 was detected and GS was confirmed.

A 67-year-old woman with asthma visited our hospital with increasing dyspnea and new-onset paresthesia and purpura in her legs. Physical examination showed a wheeze, pretibial edema, and surrounding purpura. Chest X-rays showed cardiac decompensation and an electrocardiogram revealed a new ST-T change. Laboratory data showed leukocytosis, hypereosinophilia (10,450/μL), troponin T(+), elevated BNP, and markedly elevated eosinophil cationic protein (ECP) (> 150 ng/mL). Echocardiography revealed diffuse left ventricular hypokinesis (ejection fraction 30%) with increased wall thickness. Coronary angiography was normal. Cardiac magnetic resonance imaging implied diffuse myocardial edema and subendocardial late gadolinium enhancement. Skin biopsy of purpura showed superfi cial perivascular dermatitis with remarkable eosinophilic infiltrations. No evidence of drug allergies, parasitic infection, or myeloproliferative disorder was detected. Based on these findings, a diagnosis of eosinophilic myocarditis due to Churg-Strauss syndrome was considered. She was administered prednisolone at a dose of 1 mg/kg, cyclophosphamide, and diuretics. Several markers of eosinophilic myocarditis and heart failure gradually improved, including ECP. She was discharged 30 days later with no cardiac event. Eosinophilic myocarditis is characterized by predominantly eosinophilic infi ltration. Eosinophilic granule proteins, such as ECP and major basic protein, play important roles in the pathogenesis of eosinophilic myocarditis. We experienced a rare case of eosinophilic myocarditis due to Churg-Strauss syndrome. Markedly elevated ECP played an important role in the early diagnosis and subsequent reduction in ECP served as a marker of monitoring. In an asthmatic patient with dyspnea, hypereosinophilia, and vasculitis, Churg-Strauss syndrome with eosinophilic myocarditis should be considered.

We present a case of a patient with Anton's syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton's syndrome, he might have had Charles Bonnet syndrome, characterized by both visual loss and hallucinations. Anton syndrome, is not so frequent condition and is most commonly caused by ischemic stroke. In this particular case, the patient had successive bilateral occipital ischemia as a result of massive stenoses of head and neck arteries.

Abstract Rationale: Saccharated ferric oxide has been shown to lead to elevation of fibroblast growth factor 23, hypophosphatemia, and, consequently, osteomalacia. Moreover, mineral imbalance is often observed in patients with short-bowel syndrome to some degree. Patient concerns: A 62-year-old woman with short-bowel syndrome related with multiple resections of small intestines due to Crohn disease received regular intravenous administration of saccharated ferric oxide. Over the course of treatment, she was diagnosed with tetany, which was attributed to hypocalcemia. Additional assessments of the patient revealed not only hypocalcemia, but also hypophosphatemia, hypomagnesemia, osteomalacia, and a high concentration of fibroblast growth factor 23 (314 pg/mL). Diagnoses: We diagnosed her with mineral imbalance-induced osteomalacia due to saccharated ferric oxide and short-bowel syndrome. Interventions: Magnesium replacement therapy and discontinuation of saccharated ferric oxide alone. Outcomes: These treatments were able to normalize her serum mineral levels and increase her bone mineral density. Lessons: This case suggests that adequate evaluation of serum minerals, including phosphate and magnesium, during saccharated ferric oxide administration may be necessary, especially in patients with short-bowel syndrome.

Observations are reported relating to the endogenous creatinine clearance, the Tc-99m-EDTA-complex clearance and the creatinine clearance estimated via a selected mathematical formula, with special regard to the problems of renal insufficiency and the nephrotic syndrome. The activity applied was in the range of 3.7-7.4 MBq. It was observed that measurement of the isotope clearance can also be applied to determine the endogeneous creatinine clearance in otherwise less suitable patients. A reliable result is obtained even if the renal function is restricted, but the accuracy of the method may be reduced in nephrotic syndrome cases. (author) 24 refs

Angelman syndrome with uniparental disomy due to paternal meiosis II nondisjunction.

We report a case of Angelman syndrome (AS) with paternal uniparental disomy (pUPD) of chromosome 15. This 6-year-old girl with overgrowth had frequent, but only provoked laughter, was mildly ataxic with limb hypertonia, and had no intelligible speech. She had deep-set eyes, protruding tongue, and prominent chin. The karyotype was normal. DNA analysis with microsatellites from chromosome 15 showed no inheritance of maternal alleles both within and outside the AS critical region. Proximal markers showed reduction to homozygosity of paternal alleles, intermediate markers showed nonreduction, and distal markers reduction, thus suggesting a meiosis II nondisjunction event in the father with two crossovers. This is, to our knowledge, the first reported case of AS due to meiosis II nondisjunction. We present detailed physical measurements in this patient, adding to the clinical description of the milder phenotype in AS due to pUPD.

A 6-year-old, castrated male ferret (Mustela putorius furo) was presented with progressive neurological signs consisting of a right-sided head tilt and ataxia. Neurological examination revealed hemiparesis and absence of proprioception on the right side, consistent with central vestibular syndrome. Measurement of blood glucose excluded hypoglycemia due to insulinoma. Contrast-enhanced computed tomography revealed the presence of an intracranial mass, consistent with either granuloma or neoplasia. Palliative treatment with prednisolone yielded no improvement. At postmortem examination, a final diagnosis of a choroid plexus papilloma originating from the fourth ventricle was made. This is the first report of such a tumor in a ferret.

Insight into podocyte differentiation from the study of human genetic disease: nail-patella syndrome and transcriptional regulation in podocytes.

Science.gov (United States)

Morello, Roy; Lee, Brendan

2002-05-01

In recent years, our understanding of the molecular basis of kidney development has benefited from the study of rare genetic diseases affecting renal function. This has especially been the case with the differentiation of the highly specialized podocyte in the pathogenesis of human disorders and mouse phenotypes affecting the renal filtration barrier. This filtration barrier represents the end product of a complex series of signaling events that produce a tripartite structure consisting of interdigitating podocyte foot processes with intervening slit diaphragms, the glomerular basement membrane, and the fenestrated endothelial cell. Dysregulation of unique cytoskeletal and extracellular matrix proteins in genetic forms of nephrotic syndrome has shown how specific structural proteins contribute to podocyte function and differentiation. However, much less is known about the transcriptional determinants that both specify and maintain this differentiated cell. Our studies of a skeletal malformation syndrome, nail-patella syndrome, have shown how the LIM homeodomain transcription factor, Lmx1b, contributes to transcriptional regulation of glomerular basement membrane collagen expression by podocytes. Moreover, they raise intriguing questions about more global transcriptional regulation of podocyte morphogenesis.

Protein-losing gastroenteropathy (PLGE), a rare manifestation of primary Sjögren's syndrome (SS), is characterized by profound edema and severe hypoalbuminemia secondary to excessive serum protein loss from the gastrointestinal tract and is clinically indistinguishable from nephrotic syndrome. We report a case of a 30-year-old Taiwanese woman with PLGE-associated SS. In addition to a positive Schirmer's test, she had eye-dryness, thirst, and high levels of anti-SSA antibodies, fulfilling SS criteria. PLGE diagnosis was highly appropriate given the clinical profile of hypoalbuminemia, hypercholesterolemia, pleural effusion, and ascites, with absent cardiac, hepatic, or renal disease. We were unable to perform technetium-99 m-labeled human serum albumin scintigraphy ((99m)Tc-HAS). However, the patient's edema and albumin level improved dramatically in response to a 3-month regime of oral prednisolone followed by oral hydroxychloroquine. © The Author(s) 2015.

Hyeoh Won Yu

2016-03-01

Full Text Available Adrenocorticotropin-independent adrenal hyperplasias are rare diseases, which are classified into macronodular (>1 cm and micronodular (≤1 cm hyperplasia. Micronodular adrenal hyperplasia is subdivided into primary pigmented adrenocortical disease and a limited or nonpigmented form 'micronodular adrenocortical disease (MAD', although considerable morphological and genetic overlap is observed between the 2 groups. We present an unusual case of a 44-month-old girl who was diagnosed with Cushing syndrome due to MAD. She had presented with spotty pigmentation on her oral mucosa, lips and conjunctivae and was diagnosed with multiple bone tumors in her femur, pelvis and skull base at the age of 8 years. Her bone tumor biopsies were compatible with osteoblastoma. This case highlights the importance of verifying the clinicopathologic correlation in Cushing syndrome and careful follow-up and screening for associated diseases.

Saccharated ferric oxide has been shown to lead to elevation of fibroblast growth factor 23, hypophosphatemia, and, consequently, osteomalacia. Moreover, mineral imbalance is often observed in patients with short-bowel syndrome to some degree. A 62-year-old woman with short-bowel syndrome related with multiple resections of small intestines due to Crohn disease received regular intravenous administration of saccharated ferric oxide. Over the course of treatment, she was diagnosed with tetany, which was attributed to hypocalcemia. Additional assessments of the patient revealed not only hypocalcemia, but also hypophosphatemia, hypomagnesemia, osteomalacia, and a high concentration of fibroblast growth factor 23 (314 pg/mL). We diagnosed her with mineral imbalance-induced osteomalacia due to saccharated ferric oxide and short-bowel syndrome. Magnesium replacement therapy and discontinuation of saccharated ferric oxide alone. These treatments were able to normalize her serum mineral levels and increase her bone mineral density. This case suggests that adequate evaluation of serum minerals, including phosphate and magnesium, during saccharated ferric oxide administration may be necessary, especially in patients with short-bowel syndrome.

A 62-year-old man with well-controlled diabetes mellitus developed numbness of the bilateral feet and hands, followed by subacutely progressive weakness and amyotrophy of extremities. He became bed-ridden state, and dyspnea also appeared, so he was referred to our hospital. Physical examination revealed a lean man, with dark-reddish skin pigmentation, crabbed fingers, bilateral pretibial pitting edema, and bristles in extremities. Thoracoabdominal paradoxical respiration was observed and pulmonary vesicular sounds was decreased markedly in the both lungs. Laboratory data revealed hypoproteinemia, abnormalities of endocrine system, but M-protein was not detected. Serum vascular endothelial growth factor level was quite high. Chest radiography revealed elevation of the bilateral diaphragm, the % vital capacity (%VC) was 24%, and arterial blood gas analysis showed marked hypoxia with hypercapnia. These findings suggested that his respiratory failure was induced by bilateral diaphragmatic paralysis caused by bilateral phrenic nerve palsy due to Crow-Fukase syndrome. He became somnolent because of hypercapnic narcosis, so non-invasive positive pressure ventilation (NIPPV) was started. We treated him with intravenous immunoglobulin and oral corticosteroids therapies, and after these therapies, his symptoms were remarkably recovered and NIPPV became unnecessary soon. The most frequent causes of respiratory failure in Crow-Fukase syndrome are pleural effusion and pulmonary hypertension, and only two cases of this syndrome with respiratory failure caused by bilateral diaphragmatic paralysis were reported until now. When the patients with Crow-Fukase syndrome complain of dyspnea, we should take the diaphragmatic paralysis into consideration, which may be improved by appropriate therapies.

Fungal peritonitis is a rare serious complication most commonly observed in immunocompromised patients under peritoneal dialysis. Nevertheless, this clinical condition is more difficult to treat than bacterial peritonitis. Bacterial peritonitis followed by the use of antibiotics is the main risk factor for developing fungal peritonitis. Candida spp. are more frequently isolated, and the isolation of filamentous fungi is only occasional. Here we describe a case of Fusarium solani species complex peritonitis associated with bacterial peritonitis in a female kidney transplant recipient with previous history of nephrotic syndrome. The patient has had Enterobacter sp. endocarditis and was hypertensive and diabetic. Two sequential isolates of F. solani were recovered from cultures and identified with different molecular techniques. She was successfully treated with 50 mg daily amphotericin B for 4 weeks.

Full Text Available We report a family with a rare genetic disorder arising out of mutation in the gene that encodes for the enzyme lecithin-cholesterol acyltransferase (LCAT. The proband presented with nephrotic syndrome, hemolytic anemia, cloudy cornea, and dyslipidemia. Kidney biopsy showed certain characteristic features to suggest LCAT deficiency, and the enzyme activity in the serum was undetectable. Mother and younger sister showed corneal opacity and dyslipidemia but no renal or hematological involvement. These two members had a milder manifestation of the disease called fish eye disease. This case is presented to emphasize the importance of taking family history and doing a good clinical examination in patients with nephrotic syndrome and carefully analyze the lipid fractions in these subset of patients.

Hypoparathyroidism, deafness and renal dysplasia (HDR) syndrome is a rare autosomal dominant disorder, secondary to mutations in the GATA-3 gene. Due to its wide range of penetrance and expressivity, the disease may not always be recognized. We herein describe clinical and genetic features of patients with HDR syndrome, highlighting diagnostic clues. Medical records of eight patients from five unrelated families exhibiting GATA-3 mutations were reviewed retrospectively, in conjunction with all previously reported cases. HDR syndrome was diagnosed in eight patients between the ages of 18 and 60 years. Sensorineural deafness was consistently diagnosed, ranging from clinical hearing loss since infancy in seven patients to deafness detected only by audiometry in adulthood in one single patient. Hypoparathyroidism was present in six patients (with hypocalcaemia and inaugural seizures in two out of six). Renal abnormalities observed in six patients were diverse and of dysplastic nature. Three patients displayed nephrotic-range proteinuria and reached end-stage renal disease (ESRD) between the ages of 19 and 61 years, whilst lesions of focal and segmental glomerulosclerosis were histologically demonstrated in one of them. Interestingly, phenotype severity differed significantly between a mother and son within one family. Five new mutations of GATA-3 were identified, including three missense mutations affecting zinc finger motifs [NM_001002295.1: c.856A>G (p.N286D) and c.1017C>G (p.C339W)] or the conserved linker region [c.896G>A (p.R299G)], and two splicing mutations (c.924+4_924+19del and c.1051-2A>G). Review of 115 previously reported cases of GATA-3 mutations showed hypoparathyroidism and deafness in 95% of patients, and renal abnormalities in only 60%. Overall, 10% of patients had reached ESRD. We herein expand the clinical and mutational spectrum of HDR syndrome, illustrating considerable inter- and intrafamilial phenotypic variability. Diagnosis of HDR should be

Teraki, Y; Shibuya, M; Izaki, S

2010-10-01

Drug-induced hypersensitivity syndrome (DIHS)/drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is characterized by late disease onset, fever, rash, hepatic dysfunction, haematological abnormalities, lymphadenopathy and often, human herpesvirus (HHV) reactivation. The diagnosis of DIHS is based on the combined presence of these findings. Anticonvulsants are a major cause of DIHS and may also cause Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). We examined whether SJS/TEN due to anticonvulsants display similar clinical and laboratory features seen in DIHS. Patients diagnosed with SJS or TEN due to anticonvulsants (n = 8) were examined and their clinical features and laboratory findings were compared with patients with anticonvulsant-related DIHS (n = 6). Seven of the eight patients with SJS/TEN developed symptoms > 3 weeks after starting anticonvulsants. Hepatic dysfunction was present in six patients with SJS/TEN and five patients with DIHS. Leucocytosis and/or eosinophilia was noted in seven patients with SJS/TEN and four patients with DIHS. Only one patient in the SJS/TEN group had atypical lymphocytosis; this was present in four patients with DIHS. Reactivation of HHV-6 was detected in one of the four patients tested in the SJS/TEN group, although it was seen in five of the six patients with DIHS. TSJS/TEN due to anticonvulsants may exhibit some clinical and laboratory features of DIHS. The nature of the cutaneous involvement should be emphasized in the diagnosis of DIHS. © 2009 The Author(s).

Additional manifestations can be occasionally found. Carvajal syndrome may be due to mutations in the desmocollin-2, desmoplakin, or plakophilin-2 gene. We report a family with Carvajal syndrome which additionally presented with hypoacusis, noncompaction, recurrent pharyngeal infections, oligodontia, and recurrent diarrhoea. Father and brother were also affected and had died suddenly, the father despite implantation of a cardioverter defibrillator (ICD). Genetic studies revealed the novel pathogenic mutation c.1678A > T in the desmoplakin gene resulting in the amino acid change Ile to Phe at position 560 in the index case and her brother. The index case underwent ICD implantation recently. Phenotypic manifestations of Carvajal syndrome are even broader than so far anticipated, the number of mutations in the desmoplakin gene responsible for Carvajal syndrome is still increasing, and these patients require implantation of an ICD as soon as their diagnosis is established.

Toxic nephrophaties secondary to occupational exposure to metals have been widely studied, including membranous nephropathy by mercury, which is rare. Occupational poisoning by mercury is frequent, neurological symptoms are the main form of clinical presentation. Secondary renal involvement in chronic exposure to metallic mercury can cause glomerular disease by deposit of immune-complexes. Membranous glomerulopathy and minimal change disease are the most frequently reported forms. Here we describe the case of a patient with occupational exposure to metallic mercury, where nephrotic syndrome due to membranous glomerulonephritis responded favorably to both chelation and immunosuppressive therapy.

Postoperative hemorrhage is a significant cause of morbidity and mortality following liver resection. It typically presents early within the postoperative period, and conservative management is possible in the majority of cases. We present a case of late post-hepatectomy hemorrhage associated with overt abdominal compartment syndrome resulting from a localized functional compartment within the abdomen. A 68-year-old white man was readmitted with sudden onset of upper abdominal pain, vomiting, and hemodynamic instability 8 days after an uneventful hepatic resection for metachronous colon cancer metastasis. A frozen abdomen with adhesions due to complicated previous abdominal surgeries was encountered at the first intervention, but the surgery itself and initial recovery were otherwise unremarkable. Prompt response to fluid resuscitation at admission was followed by a computed tomography of his abdomen that revealed active arterial hemorrhage in the liver resection site and hemoperitoneum (estimated volume abdominal compartment syndrome. Surgical exploration confirmed a small volume of ascites and blood clots (1.2 L) under significant pressure in his supramesocolic region, restricted by his frozen lower abdomen, which we evacuated. Dramatic improvement in his ventilatory pressure was immediate. His abdomen was left open and a negative pressure device was placed for temporary abdominal closure. The fascia was formally closed after 48 hours. He was discharged home at postoperative day 6. Intra-abdominal pressure and radiologic findings of intra-abdominal hemorrhage should be carefully interpreted in patients with extensive intra-abdominal adhesions. A high index of suspicion and detailed understanding of abdominal compartment mechanics are paramount for the timely diagnosis of abdominal compartment syndrome in these patients. Clinicians should be aware that abnormal anatomy (such as adhesions) coupled with localized pathophysiology (such as hemorrhage) can create a so

The prevalence of coronary artery disease is on the rise as the life expectancy of the population increases. However, treatment of acute coronary syndrome in the elderly patients has its own problems that have not been thoroughly addressed in the clinical trials. Since these patients are generally fragile and have multiple co-morbidities, the course of acute coronary syndrome can frequently be complicated. Infection, which co-exists either at the initial presentation or is acquired during the hospital stay, is a condition about which there is little published data. Therefore, in our study, we wanted to assess the impact of infection on mortality in octogenarians who have acute coronary syndrome METHODS: We retrospectively analyzed the data of 174 octogenarians who had been admitted to the coronary care unit with acute coronary syndrome. All-cause mortality was defined as the primary endpoint of the study. Overall 53 octogenarian patients (30.5%) had an infection along with acute coronary syndrome. The mean duration of follow-up was 10 months (1-25 months). Both in-hospital and long-term mortality were higher in these patients (18.9% vs 6.6%, p = 0.01; 52.8% vs 27.5%, p < 0.01; respectively). Kaplan-Meier analysis also showed lower cumulative survival. (p [log-rank] = 0.002). In multivariate Cox regression analysis; undergoing coronary angiography, infection (HR 1.96, 95% CI 1.15-3.34, p = 0.01), left ventricular ejection fraction and maximum C reactive protein levels were found as independent predictors of long-term survival. Infection in octogenarians who were admitted due to acute coronary syndrome was frequent and increased their mortality substantially. Copyright © 2018 Elsevier B.V. All rights reserved.

Herein we describe a case of microangiopathic antiphospholipid syndrome (MAPS) due to anti-phosphatidylserine/prothrombin complex (aPS/PT) IgM antibody successfully treated with rituximab. A significant correlation was observed between the clinical course and the aPS/PT IgM antibody titer, which can rise earlier before the appearance of clinical symptoms. Rituximab can be safely and effectively used for MAPS. Although detection of only aPS/PT IgM antibody is rare, aPS/PT IgM antibody might be associated with the pathogenesis of MAPS and might be a useful marker of disease activity. © 2017 Japan Pediatric Society.

The calcium sensing receptor (CaSR) plays an important role in calcium homeostasis. Activating mutations of CaSR cause autosomal dominant hypocalcemia by affecting parathyroid hormone secretion in parathyroid gland and calcium resorption in kidney. They can also cause a type 5 Bartter syndrome by inhibiting the apical potassium channel in the thick ascending limb of the loop of Henle in the kidney. This study presents a patient who had autosomal dominant hypocalcemia with Bartter syndrome due to an activating mutation Y829C in the transmembrane domain of the CaSR. Symptoms of hypocalcemia occurred 12 days after birth and medication was started immediately. Medullary nephrocalcinosis and basal ganglia calcification were found at 7 years old and at 17 years old. Three hypercalcemic episodes occurred, one at 14 years old and two at 17 years old. The Bartter syndrome was not severe while the serum calcium concentration was controlled, but during hypercalcemic periods, the symptoms of Bartter syndrome were aggravated.

Community-acquired methicillin-resistant Staphylococcus aureus has been spreading worldwide, including in Japan. However, few cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus have been reported in Japan. We report 2 cases, in middle-aged women, of toxic shock syndrome due to Community-acquired methicillin-resistant Staphylococcus aureus via a vaginal portal of entry. The first patient had used a tampon and the second patient had vaginitis due to a cleft narrowing associated with vulvar lichen sclerosus. Both patients were admitted to our hospital with septic shock and severe acute kidney injury and subsequently recovered with appropriate antibiotic treatment. In our review of the literature, 8 cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus were reported in Japan. In these 8 cases, the main portals of entry were the skin and respiratory tract; however, the portal of entry of Community-acquired methicillin-resistant Staphylococcus aureus from a vaginal lesion has not been reported in Japan previously.

Papillon-Lefevre syndrome (PLS) is an autosomal recessive disease that is characterized by symmetric palmoplantar keratodermatitis and severe periodontal destruction. Mutations in the cathepsin C gene (CTSC) have recently been detected in PLS. Immune dysregulation, due to a mutation in CTSC, increases the risk of pyogenic infections in PLS patients. A child with PLS is presented here with liver abscesses and peritonitis caused by Rhizopus oryzae. His liver abscess and peritonitis were cured with amphotericin B without surgical care. This is the first case in the literature liver abscess due to Rhizopus oryzae in a child with PLS.

Microdeletions on chromosome 17q12 cause of diverse spectrum of disorders and have only recently been identified as a rare cause of Mayer-Rokitansky-Kuester-Hauser-Syndrome (MRKH), which is characterized by uterus aplasia ± partial/complete vaginal aplasia in females with a regular karyotype. For the first time we report about a patient with a 17q12 microdeletion who is affected by MRKH in combination with a vascular and soft tissue disorder. Repeatedly she suffered from kidney transplant failure caused by consuming membranous nephropathy. A 38-year-old female patient had been diagnosed with right kidney aplasia, left kidney dysplasia and significantly impaired renal function during infancy. Aged 16 she had to start hemodialysis. Three years later she received her first kidney transplant. Only then she was diagnosed with MRKH. The kidney transplant was lost due to consuming nephrotic syndrome caused by de novo membranous nephropathy, as was a second kidney transplant years later. In addition, a hyperelasticity syndrome affects the patient with congenital joint laxity, kyphoscoliosis, bilateral hip dysplasia, persistent hypermobility of both elbows, knees and hips. Her clinical picture resembles a combination of traits of a hypermobile and a vascular form of Ehlers-Danlos-Syndrome, but no mutations in the COL3A1 gene was underlying. Instead, array-based comparative genomic hybridisation (CGH) detected a heterozygous 1.43 Mb deletion on chromosome 17q12 encompassing the two renal developmental genes HNF1β and LHX1. Deletions of HNF1β have recently drawn significant attention in pediatric nephrology as an important cause of prenatally hyperechogenic kidneys, renal aplasia and renal hypodysplasia. In contrast, membranous nephropathy represents an often-unaccounted cause of nephrotic syndrome in the adult population. A causative connection between theses two conditions has never been postulated, but is suggestive enough in this case to hypothesize it.

Budd-Chiari syndrome (BCS) is a rare clinical entity characterized by post-sinusoidal portal hypertension caused by the obstruction to the hepatic vein outflow. The diagnosis is suggested by hepatic scintigraphy and is usually confirmed by hepatic venography, inferior vena cavography and biopsy. The scintigraphic finding of BCS caused by the obstruction of main hepatic vein has been reported to consist typically of hypertrophy of the caudate lobe with increased radionuclide accumulation. Such a typical finding has been accounted for by the fact that the venous outflow from the caudate lobe is preserved when the main hepatic vein is obstructed. But usually, the hepatic venous outflow from the caudate lobe is also obstructed in BCS due to inferior vena caval obstruction. So hepatic scintigraphic findings of BCS due to inferior vena caval obstruction show different findings as compared with the BCS due to hepatic vein obstruction. We evaluate the hepatic scintigrams of the 13 cases of BCS due to inferior vena caval obstruction and review the literatures. The results are as follows: 1) We cannot observe the caudate lobe hypertrophy with increased uptake, which is known as a classic finding in BCS due to hepatic vein obstruction. 2) The most prominent hepatic scintigraphic findings of BCS are nonhomogenous uptake in the liver with extrahepatic uptake in the all cases. 3) We can see cold areas at the superior aspect of right hepatic lobe in 7 cases (54%). This is a useful finding suggesting BCS due to inferior vena caval obstruction.

Turner syndrome presents with one of the most frequent chromosomal aberrations in female, typically presented with growth retardation, ovarian insufficiency, facial dysmorphism, and numerous other somatic stigmata. Gigantism is an extremely rare condition resulting from an excessive growth hormone (GH) secretion that occurs during childhood before the fusion of epiphyseal growth plates. The major clinical feature of gigantism is growth acceleration, although these patients also suffer from hypogonadism and soft tissue hypertrophy. We presented a girl with mosaic Turner syndrome, delayed puberty and normal linear growth for the sex and age, due to the simultaneous GH hypersecretion by pituitary tumor. In the presented case all the typical phenotypic stigmata related to Turner syndrome were missing. Due to excessive pituitary GH secretion during the period while the epiphyseal growth plates of the long bones are still open, characteristic stagnation in longitudinal growth has not been demonstrated. The patient presented with delayed puberty and primary amenorrhea along with a sudden appearance of clinical signs of hypersomatotropinism, which were the reasons for seeking medical help at the age of 16. Physical examination of children presenting with delayed puberty but without growth arrest must include an overall hormonal and genetic testing even in the cases when typical clinical presentations of genetic disorder are absent. To the best of our knowledge, this is the first reported case of simultaneous presence of Turner syndrome and gigantism in the literature.

To investigate the expression of glomerular heparin sulfate (HS) in paediatric patients with minimal change nephritic syndrome (MCNS). The kidyney tissues were collected by biopsy from 13 paediatric patients with MCNS, while 5 normal renal biopsy samples were used as control. HS in glomeruli was analysed by indirect immunofluorescence staining using four different monoclonal antibodies, Hepss1, 3G10, JM403 and 10E4, which all recognize distinct HS species and each interacts with a specific HS domain. The concentrations of urine heparan sulfate also were measured by enzyme-linked immunosorbent assay (Elisa). Expression of HS fine domains was aberrant in paediatric patients compared with control subjects. Children with MCNS in replase showed a decreased glomerular expression of 10E4, JM403 and Hepss1 (P peadiatric patients with MCNS when compared with that in control subjects (P < 0.01). These results suggest that loss of heparan sulphate in renal tissue may play a role in the pathogenesis of MCNS proteinuria.

Full Text Available This study retrospectively investigates the indications and results of renal biopsy in children to determine the patterns of childhood kidney disease in a single tertiary children′s hospital in Egypt. We included all the patients who underwent ultrasound-guided renal biopsy from 1998 to 2012. All the kidney biopsies were studied under light microscopy, while immunofluorescence and electron microscopy were performed when indicated. A total of 1246 renal biopsies were performed over 15 years, on 1096 patients. The mean age of the patients at the time of biopsy was 9.2 ± 3.7 years. The main indication for a biopsy was the steroid-resistant nephrotic syndrome (n = 354, 28.4%, followed by the atypical nephrotic syndrome (n = 250, 20.1%, and renal abnormalities in the systemic diseases (n = 228, 18.3 %. In the 1226 pathologically diagnosed specimens, primary glomerulonephritis was the most common finding (n = 826, 67.4%, followed by secondary glomerulonephritis (n = 238, 19.4%. The most common causes of primary glomerulonephritis were Minimal Change Disease (MCD (n = 267, 21.8%, diffuse proliferative glomerulonephritis (n = 188, 15. 3%, and focal proliferative glomerulonephritis (n = 164, 13.3%. Lupus nephritis (n = 209, 17% was the most common cause of secondary glomerulonephritis. We conclude that the steroid-resistant nephrotic syndrome was the most frequent indication for biopsy and minimal change disease was the most common histopathological finding in our population.

IgG4-related disease is a recently described pathologic entity. This is the case of a patient with nephrotic syndrome and lymphadenopathy due to IgG4-related disease. Such a kidney involvement is quite peculiar and has only been described a few times recently. Renal biopsy showed a glomerular involvement with membranous glomerulonephritis in association with a tubulo-interstitial nephropathy. Moreover, the patient was not suffering from pancreatitis. The patient is a middle-aged man of Moroccan origin. He has developed recurrent episodes of diffuse lymphadenopathies, renal failure and nephrotic syndrome. Renal biopsies showed membranous glomerulonephritis. The diagnostic approach of this atypical presentation is discussed in this case report as well as diagnostic criteria, therapeutic strategies, biomarkers and pathophysiology of IgG4-related disease. IgG4-related membranous glomerulonephritis is a well-established cause of membranous glomerulonephritis. It must be sought after in every patient with a previous diagnosis of IgG4-related disease and in every patient with this histological finding on renal biopsy. Corticoids are still the first-line treatment of IgG4-related disease. New therapeutic strategies are needed to avoid glucocorticoids long term side-effects. Interestingly, the patient was prescribed cyclophosphamide in addition to glucocorticoids for an immune thrombocytopenia. This treatment had a very good impact on his IgG4-related disease.

Taurine Supplementation Alleviates Puromycin Aminonucleoside Damage by Modulating Endoplasmic Reticulum Stress and Mitochondrial-Related Apoptosis in Rat Kidney

Full Text Available Taurine (TAU is a sulfur-containing beta amino acid that is not involved in protein composition and anabolism, conditionally essential in mammals provided through diet. Growing evidence supports a protective role of TAU supply in osmoregulation, calcium flux, and reduction of inflammation and oxidant damage in renal diseases like diabetes. Endoplasmic reticulum (ER stress, due to abnormal proteostasis, is a contributor to nephrotic syndrome and related renal damage. Here, we investigated the effect of dietary TAU (1.5% in drinking water for 15 days in an established rat model that mimics human minimal change nephrosis, consisting of a single puromycin aminonucleoside (PAN injection (intraperitoneally 15 mg/100 g body weight, with sacrifice after eight days. TAU limited proteinuria and podocytes foot processes effacement, and balanced slit diaphragm nephrin and glomerular claudin 1 expressions. In cortical proximal tubules, TAU improved lysosomal density, ER perimeter, restored proper ER-mitochondria tethering and mitochondrial cristae, and decreased inflammation. Remarkably, TAU downregulated glomerular ER stress markers (GRP78, GRP94, pro-apoptotic C/EBP homologous protein, activated caspase 3, tubular caspase1, and mitochondrial chaperone GRP75, but maintained anti-apoptotic HSP25. In conclusion, TAU, by targeting upstream ER stress separate from mitochondria dysfunctions at crucial renal sites, might be a promising dietary supplement in the treatment of the drug-resistant nephrotic syndrome.

Full Text Available Refeeding syndrome (RS is a serious and potentially fatal disorder. It is caused by a shift of fluids, sodium, potassium, magnesium and phosphorus as well changes in the metabolism of glucose, protein, fat and vitamins following the refeeding of malnourished patients, whether enterally or parenterally. RS has rarely been reported in patients with advanced kidney disease probably due to the pre-existing hyperphosphatemia, hypermagnesemia and hyperkalemia in these patients. In the following report, we present a patient with nephronophthisis type 1 deletion syndrome in whom her main previous nutrition was limited to simply rehydration to avoid renal replacement therapy. On presentation, she was cachectic and dehydrated with advanced kidney failure. She was treated with medical nephrectomy using non-steroidal anti-inflammatory drugs and then placed on maintenance hemodialysis. Percutaneous endoscopic gastrostomy was used for her initial feeding. Care was exercised during her early refeeding with regard to correction of fluids and essential electrolytes, viz. potassium, phosphorus and magnesium, as well as multivitamins to avoid the cardiovascular and neurological complications of RS. However, the changes in the gut, pancreas and liver as well as her hyperlipidemia were a clear obstacle. Fortunately, the ileus and pancreatitis she developed on refeeding improved dramatically with a decrease of the feeding dose to half; however, the liver abnormalities and hyperlipidemia were severe and slow to recover. These improved after addition of ursodeoxycholic acid and permitted successful increase of the dose of feeding subsequently.

1975-02-01

Erythrocyte 2,3-diphosphoglycerate (2,3-DPG) concentrations in 10 patients with acute lymphoblastic leukemia rose 21.3%(P smaller than 0.02) after 3 weeks of prednisone and vincristine therapy, and returned to pretreatment level 2 weeks after therapy had been discontinued. The mean 2,3-DPG level of three patients on vincristine alone did not vary significantly from the control level of the leukemia patients on prednisone and vincristine. No significant change in serum inorganic phosphate level was observed. The mean erythrocyte 2,3-DPG concentration of 17 nephrotic syndrome patients being treated with chronic prednisone therapy was 14.0% higher than a control group of 20 nephrotic syndrome patients not being treated with prednisone (P small than 0.01). A significant positive correlation was observed between the dose of prednisone and 2,3-DPG level.

To compare Doppler ultrasonography with laboratory tests in evaluation of diabetic nephropathy. Fifty-five patients (mean age = 60, M : F = 26 : 29) with diabetes mellitus underwent renal Doppler ultrasonography. Resistive indices were compared with degree of proteinuria, serum creatinine level, and creatinine clearance rate. Eighteen patients who showed no proteinuria or microscopic proteinuria had a mean resistive index (RI) of 0.72 (SD, 0.05), 16 patients with macroscopic proteinuria without nephrotic syndrome had a mean RI of 0.82 (SD, 0.13), and 21 patients with nephrotic syndrome had a mean RI of 0.90 (SD, 0.12). Renal RI correlated highly with serum creatinine level (r = 0.62) and creatinine clearance rate (r = -0.43). Renal Doppler ultrasonography provides a useful indication of renal function in diabetic nephropathy but cannot offer an advantage over conventional laboratory test

2008-03-01

Usher syndrome (USH) is an autosomal recessive condition characterized by sensorineural hearing loss, vestibular dysfunction, and visual impairment due to retinitis pigmentosa. Truncating mutations in the cadherin-23 gene (CDH23) result in Usher syndrome type 1D (USH1D), whereas missense mutations affecting strongly conserved motifs of the CDH23 protein cause non-syndromic deafness (DFNB12). Four missense mutations constitute an exception from this genotype-phenotype correlation: they have been described in USH1 patients in homozygous state. Using a minigene assay, we have investigated these changes (c.1450G>C, p.A484P; c.3625A>G, p.T1209A; c.4520G>A, p.R1507Q; and c.5237G>A, p.R1746Q) for a possible impact on mRNA splicing which could explain the syndromic phenotype. While in silico analysis suggested impairment of splicing in all four cases, we found aberrant splicing for only one mutation, p.R1746Q. However, splicing was normal in case of p.A484P, p.T1209A and p.R1507Q. These three latter CDH23 missense mutations could interfere with functions of both, the auditory and the visual system. Alternatively, they could represent rare non-pathogenic polymorphisms.

Full Text Available Fanconi syndrome results from a generalized abnormality of the proximal tubules of the kidney and owing to phosphate depletion can cause hypophosphatemic osteomalacia. Adefovir dipivoxyl (ADV effectively suppresses hepatitis B virus replication but exhibits nephrotoxicity when administered at a low dosage. We report two cases of Fanconi syndrome induced by ADV at 10 mg/day to call for regular screening for evidence of proximal tubular dysfunction and detailed bone metabolic investigations for prompt detection of ADV nephrotoxicity is critically important to ensure timely drug withdrawal before the development of irreversible tubulointerstitial injury.

Adrenocorticotropic hormone (ACTH) or corticosteroids seemed to cause brain atrophy in intants. We studied the atrophy which was caused by these drugs with computed tomography (CT). 1) Nine cases of infantile spasms examined before, during and after ACTH therepy with CT. Brain atrophy on CT was observed immediately after the completion of ACTH therapy. The brain atrophy receded slightly after several months. It was more marked in younger patients, in cases treated by hight doses of ACTH and in cases where brain atrophy had already been obserbed before ACTH therapy. 2) Twenty cases of infantile spasms or Lennox Gastaut syndrome were examined after ACTH therapy with CT. Brain atrophy was observed in twelve cases. Main features of brain atrophy were the enlargement of sylvian fissure and the widening of subarachnoid space at the frontal or temporal region. Mental retardation was observed in eighteen cases. 3) Two cases of nephrotic syndrome were treated with pulse therapy of prednisolone. CT was carried out before and after treatment. Atrophy of cerebrum was observed in these cases. 4) A case of infantile spasms treated with anticonvulsants without ACTH was studied by electroencephalography (EEG) and CT. The abnormal pattern of EEG was markedly corrected, while brain atrophy on CT was not observed after the therapy. Because of these observations the use of ACTH has to be reconsidered. ACTH should be the drug of second choice for the therapy of infantile spasms and should be used in case other anticonvulsants have no effect. ACTH should be used at lower dosages and for shorter periods of time. (author)

Full Text Available Brugada Syndrome is a rare cause of sudden cardiac arrest and has a unique ECG pattern. In fact, with ST-segment elevation down sloping in the right precordial leads (v1-v3, RBBB pattern in lateral leads and J-point elevation is revealed. We must notice and avoid trigger factors of this syndrome during general anesthesia. Patient is a 39 old man who attended to emergency department with sudden cardiac arrest and resuscitate. He was transferred to ICU for management of hypoxic ischemic encephalopathy. Complementary studies concluded the diagnosis of Brugada syndrome. We must consider Brugada syndrome within patients with family history of sudden cardiac arrest. Moreover, we must avoid trigger factors of this syndrome such as fever, bradicardia and electrolyte abnormality (specialy Na, Ca abnormalities during general anesthesia and if they appear, we should treat them.

Takotsubo syndrome is characterized by predominantly medial-apical transient left ventricular dysfunction, which is typically triggered by physical or emotional stress. The present article reports the case of a 61-year-old female patient presenting with dizziness, excessive sweating, and sudden state of ill feeling following an episode involving intense emotional stress. The physical examination and electrocardiogram were normal upon admission, but the troponin I and creatine kinase-MB concentrations were increased. Acute myocardial infarction without ST segment elevation was suspected, and coronary angiography was immediately performed, which showed severe diffuse left ventricular hypokinesia, medial-apical systolic ballooning, and a lack of significant coronary injury. The patient was referred to the intensive care unit and was successfully treated with supportive therapy. As this case shows, Takotsubo syndrome might simulate the clinical manifestations of acute myocardial infarction, and coronary angiography is necessary to distinguish between both myocardial infarction and myocardial infarction in the acute stage. The present patient progressed with spontaneous resolution of the ventricular dysfunction without any sequelae.

Dubin-Johnson syndrome is a chronic, benign, intermittent jaundice, mostly of conjugated hyperbilirubinemia. The level of bilirubin is not expected to be more than 20 mg/dl in this syndrome. In this article, we report a patient who was evaluated for hyperbilirubinemia and liver function test abnormalities and diagnosed with Dubin-Johnson syndrome coexisting with hereditary spherocytosis. We suggest that other diseases should be investigated if patients with Dubin-Johnson syndrome present with severe hyperbilirubinemia. Dubin-Johnson syndrome accompanied by hemolytic diseases might also have high coproporphyrin levels (as in Rotor's syndrome) than expected in pure Dubin-Johnson syndrome.

Kallmann syndrome and ichthyosis: a case of contiguous gene deletion syndrome

Full Text Available Kallmann syndrome is a genetically heterogeneous form of hypogonadotropic hypogonadism caused by gonadotropin-releasing hormone deficiency and characterized by anosmia or hyposmia due to hypoplasia of the olfactory bulbs; osteoporosis and metabolic syndrome can develop due to longstanding untreated hypogonadism. Kallmann syndrome affects 1 in 10 000 men and 1 in 50 000 women. Defects in 17 genes, including KAL1, have been implicated. Kallmann syndrome can be associated with X-linked ichthyosis, a skin disorder characterized by early onset dark, dry, irregular scales affecting the limb and trunk, caused by a defect of the steroid sulfatase gene (STS. Both KAL1 and STS are located in the Xp22.3 region; therefore, deletions in this region cause a contiguous gene syndrome. We report the case of a 32-year-old man with ichthyosis referred for evaluation of excessive height (2.07 m and weight (BMI: 29.6 kg/m2, microgenitalia and absence of secondary sex characteristics. We diagnosed Kallmann syndrome with ichthyosis due to a deletion in Xp22.3, a rare phenomenon.

Six cases of vascular compromise after hyaluronic injection are reported. Clinical symptoms realized a Nicolau syndrome, which is characterized by immediate pain, livedoid pattern and a few days later by the appearance of scabs and skin necrosis. This type of complication is rare, but may be dramatic and injectors must be aware of that. A thorough knowledge of facial anatomy is mandatory to avoid the risky facial areas. The use of a flexible cannula instead of a sharp needle has much less risk of hurting vessels and must be preferred. The support of the patient is discussed and a treatment protocol is proposed.

2017-03-01

Posterior reversible encephalopathy syndrome (PRES) is associated with several symptoms; of those, visual acuity loss, light oversensitivity (photophobia), and light flashes (photopsia) are known as PRES-related eye symptoms. We report a post-partum woman with PRES associated with hemolysis, elevated liver enzymes, and low platelets syndrome (HELLP), in whom color vision abnormality (achromatopsia) was the sole manifestation. Cesarean section was performed at 28 weeks due to headache, epigastralgia, and severe hypertension. HELLP became evident after delivery. On post-partum day 1, she complained of achromatopsia, stating: "all things look brownish-gray". Ophthalmologic examination was normal, but brain magnetic resonance imaging showed occipital lobe lesions, indicative of PRES, and, interestingly, also color vision center (area V4) lesions, suggesting that the achromatopsia had been caused by brain damage. It may be prudent to question HELLP patients concerning achromatopsia. © 2017 Japan Society of Obstetrics and Gynecology.

Measuring the level of serum lipase has been used for the clinical diagnosis of acute pancreatitis. Reports showed that the serum lipase level increased in patients of clinical renal failure. In this study, we aimed to measure the change of serum lipase levels in chronic kidney diseases and determine whether it could serve as a clinical laboratory index for clinical renal failure diagnosis. Materials: The OLYMPUS AU5400 automatic biochemical analyzer was used to determine the serum levels of lipase and creatinine. The study included 120 cases in the clinical renal failure group, 76 cases in the nephrotic syndrome group, 81 cases in the chronic nephritis group, and 80 healthy controls from our hospital volunteers in the same period. We then compared the lipase levels and conducted statistical analyses among these groups. The serum lipase levels were 15.3 U/L, 79.8 U/L, 45.1 U/L, and 51.0 U/L in the normal control, clinical renal failure, nephrotic syndrome, and chronic nephritis groups, respectively. The lipase levels in the groups with diseases were significantly different compared with that of the normal control group (p renal failure group was significantly higher than that of the nephrotic syndrome group and chronic nephritis group (p chronic nephritis group (p > 0.05) was observed. Moreover, an association of the serum lipase with disease progression was observed in the study. Serum lipase is an effective serological index which can reflect the clinical changes in the clinical renal failure and tends to increase through the progression of renal dysfunction.

Recurrent Syncope Due to Carotid Sinus Hypersensitivity and Sick Sinus Syndrome

Full Text Available Syncope is a sudden and brief loss of consciousness with postural tone. Its recovery is usually spontaneous. There are various causes of syncope including cardiac, vascular, neurologic, metabolic and miscellaneous origins. The tracing is usually time-consuming and costly. The diagnosis of carotid sinus syncope may sometimes be difficult since the symptoms are nonspecific, especially in older persons. Here, we report the case of a 72-year-old woman who sought medical attention at our hospital due to repeated syncope episodes over the previous 5 years. Neurologic examinations showed negative results (including brain computed tomography. Twenty-four-hour ambulatory electrocardiogram monitoring showed atrial and ventricular premature contractions only. Electrophysiologic study disclosed prolonged corrected sinus node recovery time (1,737 ms with poor atrioventricular conduction. Drop of blood pressure together with sinus bradycardia developed after left side carotid sinus massage. Both carotid sinus hypersensitivity with sick sinus syndrome contributed to this patient's syncope, and after pacemaker placement together with selective serotonin reuptake inhibitor treatment, she was free from syncope thereafter.

2012-07-01

A 62-year-old-man treated for nephrotic syndrome with steroid developed acute pain of herpes zoster after immobility of the shoulder. Steroids might have suppressed the first symptoms of pain. But immobility probably appeared as VZV infection developing to spinal ventral root. Suprascapular nerve block was effective for severe pain of the right arm. Sympathetic nerve contained in suprascapular nerve might have been blocked. Sympathetically maintained pain may occur when primary afferent neurons are excited by inflammation due to VZV infection. Pain was abolished 17 weeks after the onset of rash using blocks three times and amitriptyrin and valproic acid. Immobility was resolved seven months after the onset of rash.

The effect of anxiety and depression on patients with acute coronary syndromes (ACS) warrants investigation, especially during periods of economic crisis. To investigate the relation between anxiety and depression in patients presenting with ACS due to financial crisis and to investigate whether these two entities could predict long-term cardiovascular mortality. Anxiety and depression symptoms were assessed in 350 patients (210 men) presenting with ACS, with 70 (20%) patients showing elevated scores (Hellenic Heart Failure Protocol). Over a mean follow-up of 48 months there were 36 (10%) cardiovascular deaths. Cox proportional hazards models adjusted for other prognostic factors (including age, sex, marital status, creatinine levels, left ventricular ejection fraction, heart failure, atrial fibrillation, previous hospitalisation, and baseline medications) showed that elevated anxiety and depression scores significantly predicted cardiovascular mortality (primary outcome) and all-cause mortality. Elevated anxiety and depression symptoms are related to cardiovascular mortality due probably to financial crisis, even after adjustment for other prognostic indicators in patients with ACS, who received optimised medical treatment.

Nance-Horan syndrome in females due to a balanced X;1 translocation that disrupts the NHS gene: Familial case report and review of the literature.

2018-01-01

The Nance-Horan syndrome is an X-linked disorder characterized by congenital cataract, facial features, microcornea, microphthalmia, and dental anomalies; most of the cases are due to NHS gene mutations on Xp22.13. Heterozygous carrier females generally present less severe features, and up to 30% of the affected males have intellectual disability. We describe two patients, mother and daughter, manifesting Nance-Horan syndrome. The cytogenetic and molecular analyses demonstrated a 46,X,t(X;1)(p22.13;q22) karyotype in each of them. No copy-number genomic imbalances were detected by high-density microarray analysis. The mother had a preferential inactivation of the normal X chromosome; expression analysis did not detect any mRNA isoform of NHS. This is the first report of Nance-Horan syndrome due to a skewed X chromosome inactivation resulting from a balanced translocation t(X;1) that disrupts the NHS gene expression, with important implications for clinical presentation and genetic counseling.

This article is the first in a series presenting the strongest published evidence for physical and rehabilitation medicine (PRM) to date coming from the Cochrane Collaboration. The intent of the series is to stimulate ideas for reviews and research in neglected areas of PRM. To systematically review the rehabilitation contents of the Cochrane Collaboration on disabilities due to spinal disorders or pain syndromes in adults. The Cochrane Database of Systematic Reviews was searched at the end of June 2013 for articles relevant for PRM about disabilities resulting from spinal disorders or pain syndromes in adults. Retrieved papers were classified according to the PRM approach: active therapies, which require active participation by patients to achieve treatment goals, and passive treatments, which rely on the application of external forces. The quality of the reviews was checked against the AMSTAR checklist. Reviews on spinal disorders or pain syndromes were found in the Cochrane Back Group (CBG) and in the Pain, Palliative and Supportive Care Group (CPPSCG). Thirty-eight (42.8%) of 89 Cochrane reviews in the CBG and 7 (2.4%) of 293 Cochrane reviews in the CPPSCG were included. All were of high quality (range, 8-11 points out of 11 on the AMSTAR checklist). The contents of the reviews are given in detail. This review presents an overview of the current evidence for PRM in the treatment of disabilities due to spinal disorders or pain syndromes in adults. Within PRM there is ample space for research in the Cochrane Collaboration and for producing original studies (randomized controlled trials [RCTs]). To apply evidence-based clinical practice, clinicians must be familiar with the current best evidence.

Heavy-chain deposition disease (HCDD) is a rare complication of plasma cell dyscrasia in which monoclonal heavy chains deposit in glomerular and tubular basement membranes of the kidney. Clinical and pathologic features of HCDD have been well described in case reports and series, but evidence supporting specific therapies is sparse. Historically, the disease has had a poor prognosis, intensifying the need to clarify optimal treatments. We describe 3 cases of HCDD with biopsy-proven glomerular involvement, severe nephrotic syndrome, and decline in kidney function that were treated successfully with bortezomib, a proteasome inhibitor. None of these patients had multiple myeloma. In all cases, bortezomib-based therapy resulted in sustained resolution of nephrotic syndrome and improvement in kidney function. All 3 patients developed peripheral neuropathy; otherwise, treatment was well tolerated. To our knowledge, this is the first description of the clinical effectiveness of bortezomib against HCDD.

We report a case of a 32-year-old man with hyper IgE syndrome (Job syndrome) who developed Fournier gangrene due to infectious multiple atheromas of the scrotal skin that progressed to the right groin and thigh. The patient required surgical debridement and subsequent skin grafting. This is a rare case of Fournier gangrene associated with hyper IgE syndrome (Job syndrome). When a patient without diabetes mellitus has repeated infections and atopic-like dermatitis, Job syndrome should be considered.

Invasive pneumococcal disease is an uncommon and notifiable disease in Singapore. It is often associated with significant morbidity and mortality. We report a rare case of invasive pneumococcal bacteraemia due to parotitis in a patient with systemic sclerosis and secondary Sjögren's syndrome. We also present a retrospective review of Streptococcus pneumoniae bacteraemia cases in Singapore General Hospital from January 2011 to April 2016. A 59-year-old Malay lady with a history of systemic sclerosis with secondary Sjögren's syndrome presented with fever and left parotid gland swelling. Clinical examination revealed poor salivary pooling and left parotid swelling without fluctuance. Ultrasound of the left parotid gland confirmed acute parotitis without evidence of abscess or sialolithiasis. Blood cultures were positive for S. pneumoniae . She was diagnosed to have invasive pneumococcal bacteraemia secondary to acute parotitis, and treated with intravenous benzylpenicillin with clearance of bacteraemia after 3 days. Upon discharge, her antibiotics were changed to intravenous ceftriaxone to facilitate outpatient parenteral antibiotic therapy for another 2 weeks. She responded favourably to antibiotics at follow-up, with no complications from the bacteraemia. A review of the microbiological records of the Singapore General Hospital revealed 116 cases of pneumococcal bacteraemia, most (80.3 %) of which were due to pneumonia. None were due to parotitis. S. pneumoniae parotitis and subsequent bacteraemia is rare. Prompt recognition of the disease and appropriate use of antibiotics are important. This case highlights that close communication between healthcare workers (microbiologist, rheumatologist and infectious disease specialist) is essential in ensuring good clinical outcomes in patients with a potentially fatal disease.

2012-05-01

Full Text Available Abstract Background Microdeletions on chromosome 17q12 cause of diverse spectrum of disorders and have only recently been identified as a rare cause of Mayer-Rokitansky-Kuester-Hauser-Syndrome (MRKH, which is characterized by uterus aplasia ± partial/complete vaginal aplasia in females with a regular karyotype. For the first time we report about a patient with a 17q12 microdeletion who is affected by MRKH in combination with a vascular and soft tissue disorder. Repeatedly she suffered from kidney transplant failure caused by consuming membranous nephropathy. Case presentation A 38-year-old female patient had been diagnosed with right kidney aplasia, left kidney dysplasia and significantly impaired renal function during infancy. Aged 16 she had to start hemodialysis. Three years later she received her first kidney transplant. Only then she was diagnosed with MRKH. The kidney transplant was lost due to consuming nephrotic syndrome caused by de novo membranous nephropathy, as was a second kidney transplant years later. In addition, a hyperelasticity syndrome affects the patient with congenital joint laxity, kyphoscoliosis, bilateral hip dysplasia, persistent hypermobility of both elbows, knees and hips. Her clinical picture resembles a combination of traits of a hypermobile and a vascular form of Ehlers-Danlos-Syndrome, but no mutations in the COL3A1 gene was underlying. Instead, array-based comparative genomic hybridisation (CGH detected a heterozygous 1.43 Mb deletion on chromosome 17q12 encompassing the two renal developmental genes HNF1β and LHX1. Conclusions Deletions of HNF1β have recently drawn significant attention in pediatric nephrology as an important cause of prenatally hyperechogenic kidneys, renal aplasia and renal hypodysplasia. In contrast, membranous nephropathy represents an often-unaccounted cause of nephrotic syndrome in the adult population. A causative connection between theses two conditions has never been postulated, but

Renal involvement in the antiphospholipid syndrome (APS)-APS nephropathy.

Tektonidou, Maria G

2009-06-01

Although the kidney represents a major target organ in antiphospholipid syndrome (APS), renal involvement in APS was poorly recognized until recently. The most well-recognized renal manifestations of APS are the renal artery thrombosis/stenosis, renal infarction, hypertension, renal vein thrombosis, end-stage renal disease, increased allograft vascular thrombosis, some types of glomerular disease, and a small-vessel vaso-occlusive nephropathy, recently defined as APS nephropathy. APS nephropathy was first described in primary APS patients, characterized by acute thrombotic lesions in glomeruli and/or arterioles (thrombotic microangiopathy) and chronic vascular lesions such as fibrous intimal hyperplasia of arterioles and interlobular arteries, organized thrombi with or without recanalization, and fibrous arterial and arteriolar occlusions or focal cortical atrophy. APS nephropathy was also detected in further studies including patients with systemic lupus erythematosus (SLE)-related APS and SLE/non-APS patients with positive antiphospholipid antibodies, independently of lupus nephritis. The same histologic lesions, especially thrombotic mictroangiopathy, were also observed in patients with catastrophic APS. The most frequent clinical and laboratory characteristics of APS nephropathy in all the above groups of patients are hypertension (often severe), proteinuria (ranging from mild to nephrotic range), hematuria, and acute or chronic renal insufficiency.

2009-01-01

Background and Aims Although the clinical phenotype of Lynch syndrome (also known as Hereditary Nonpolyposis Colorectal Cancer) has been well described, little is known about disease in PMS2 mutation carriers. Now that mutation detection methods can discern mutations in PMS2 from mutations in its pseudogenes, more mutation carriers have been identified. Information about the clinical significance of PMS2 mutations is crucial for appropriate counseling. Here, we report the clinical characteristics of a large series of PMS2 mutation carriers. Methods We performed PMS2 mutation analysis using long range PCR and MLPA for 99 probands diagnosed with Lynch syndrome-associated tumors showing isolated loss of PMS2 by immunohistochemistry. Penetrance was calculated using a modified segregation analysis adjusting for ascertainment. Results Germline PMS2 mutations were detected in 62% of probands (n = 55 monoallelic; 6 biallelic). Among families with monoallelic PMS2 mutations, 65.5% met revised Bethesda guidelines. Compared with the general population, in mutation carriers, the incidence of colorectal cancer was 5.2 fold higher and the incidence of endometrial cancer was 7.5 fold higher. In North America, this translates to a cumulative cancer risk to age 70 of 15–20% for colorectal cancer, 15% for endometrial cancer, and 25–32% for any Lynch syndrome-associated cancer. No elevated risk for non-Lynch syndrome-associated cancers was observed. Conclusions PMS2 mutations contribute significantly to Lynch syndrome but the penetrance for monoallelic mutation carriers appears to be lower than that for the other mismatch repair genes. Modified counseling and cancer surveillance guidelines for PMS2 mutation carriers are proposed. PMID:18602922

Corticosteroid-induced asthma: a manifestation of limited hyperinfection syndrome due to Strongyloides stercoralis.

Sen, P; Gil, C; Estrellas, B; Middleton, J R

1995-09-01

Inadequate therapeutic response to parenteral corticosteroids in patients with acute bronchial asthma is infrequent. We report four patients whose bronchial asthma symptoms worsened after treatment with parenteral corticosteroids. All had larvae of Strongyloides stercoralis in the stool. The new attack or the exacerbation of asthma appeared to be precipitated by systemic corticosteroid administration. The paradoxic therapeutic response of asthma to glucocorticoides was the major pulmonary manifestation of Strongyloides superinfection; there was no evidence of other organ involvement. Individuals with new onset of bronchial asthma or worsening of asthmatic episodes concurrent with the use of systemic corticosteroids should have thorough investigation for possible superinfection due to Strongyloides stercoralis. This is particularly important for patients who have resided in areas where intestinal helminthic infections are endemic. Discontinuance of steroid therapy or reduction in dosage of parenteral steroids appears necessary. Treatment with thiabendazole appears to be effective in patients with limited hyperinfection syndrome.

Full Text Available Identification of the profile of glomerular disease in a particular geographical region is of fundamental academic, clinical and epidemiological importance. It helps in the recognition of specific risk factors and subsequent planning for adequate prevention. In the present study, 1234 consecutive renal biopsies referred to the nephropathology team of Cairo University over two years were retrospectively analyzed. The main indications for biopsy included nephrotic syndrome, persistent sub-nephrotic proteinuria, recurrent hematuria, suspected secondary hypertension, lupus nephritis and acute and chronic renal failure of undetermined etiology. Proliferative forms of glomerulonephritis [GN] (32.1% and focal and segmental glomerulosclerosis [FSGS] were the most prevalent lesions among patients with the nephrotic syndrome (22.6%. In subjects with sub-nephrotic proteinuria, FSGS was the principal lesion followed by proliferative lesions. Although all forms of GN were encountered in those presenting with recurrent hematuria, mesangioproliferative GN and FSGS were significantly more frequent. IgA glomerular deposits were detected in 9.8% of all GNs and 15% of those presenting with hematuria. One half of the biopsies obtained for the assessment of suspected secondary hypertension showed only changes compatible with the effect of hypertension per se, i.e. nephroangiosclerosis. On the other hand, a parenchymal renal lesion was found in 52.9% of biopsies. The common glomerular pathologies in patients with lupus nephritis were Classes III and IV. Among patients with chronic renal failure, the predominant lesion was chronic interstitial nephritis (32.6%. An acute interstitial inflammatory element was also detected in 8.4% of cases. About one third of the biopsies obtained for acute renal failure showed acute tubular (11% or cortical (13.2% necrosis. Another third showed vasculitis (17.6% or acute interstitial nephritis (14.3%, and the remaining showed chronic

The ciliopathies represent an umbrella group of >50 clinical entities that share both clinical features and molecular etiology underscored by structural and functional defects of the primary cilium. Despite the advances in gene discovery, this group of entities continues to pose a diagnostic challenge, in part due to significant genetic and phenotypic heterogeneity and variability. We consulted a pediatric case from asymptomatic, non-consanguineous parents who presented as a suspected ciliopathy due to a constellation of retinal, renal, and skeletal findings. Although clinical panel sequencing of genes implicated in nephrotic syndromes yielded no likely causal mutation, an oligo-SNP microarray identified a ~20-Mb region of homozygosity, with no altered gene dosage, on chromosome 16p13. Intersection of the proband's phenotypes with known disease genes within the homozygous region yielded a single candidate, IFT140, encoding a retrograde intraflagellar transport protein implicated previously in several ciliopathies, including the phenotypically overlapping Mainzer-Saldino syndrome (MZSDS). Sanger sequencing yielded a maternally inherited homozygous c.634G>A; p.Gly212Arg mutation altering the exon 6 splice donor site. Functional studies in cells from the proband showed that the locus produced two transcripts: a majority message containing a mis-splicing event that caused a premature termination codon and a minority message homozygous for the p.Gly212Arg allele. Zebrafish in vivo complementation studies of the latter transcript demonstrated a loss of function effect. Finally, we conducted post-hoc trio-based whole exome sequencing studies to (a) test the possibility of other causal loci in the proband and (b) explain the Mendelian error of segregation for the IFT140 mutation. We show that the proband harbors a chromosome 16 maternal heterodisomy, with segmental isodisomy at 16p13, likely due to a meiosis I error in the maternal gamete. Using clinical phenotyping

2018-04-01

Full Text Available Management of anaphylaxis includes adrenaline, a life-saving drug, however appropriate dosing and administration are of crucial importance due to serious side effects. We present a 15-year-old female with anaphylactic reaction manifesting as acute coronary syndrome and pulmonary edema following the administration of adrenaline as an intravenous bolus. Focusing on anaphylaxis, adrenaline and coronary symptoms, this report discussed the interactions between three intertwining entities: Kounis syndrome, Takotsubo cardiomyopathy, and adrenaline-induced coronary vasospasm, and challenges in differential diagnosis. Brugada syndrome (cardiac autonomic dysfunction and clinical manifestation of the patient was also evaluated. Early consideration of adrenaline at the appropriate dose and administration route is essential in anaphylaxis management. Kounis syndrome should be considered in those presenting with allergy symptoms and chest pain and adrenaline should be used carefully due to possible risks of worsening coronary symptoms in patients with Kounis syndrome. This report also highlights a very rare side effect of adrenaline; the drug, which constitutes the cornerstone of anaphylaxis management, has a potential to trigger allergy itself due to metabisulfite-containing preservative.

2016-01-01

The (18)F-FDG PET/CT scan has been suggested for whole-body imaging to identify ectopic adrenocorticotrophic hormone secreting tumours, but there are some challenges involved. The case of a patient is presented, who was admitted with the pre-diagnosis of ectopic ACTH syndrome. On the CT, a nodular lesion was detected in the medial segment of the right lung. The FDG uptake of the lesion seemed to be increased visually, but was not pathological quantitatively (SUVmax: 1.8) on the PET/CT. There was also diffuse increased uptake (SUVmax: 14.2) in the enlarged adrenal glands. The lesion was reported as a possible malignant lesion with low FDG affinity, such as a low grade neuroendocrine tumour, while the diffuse enlarged adrenal glands with high uptake were interpreted as diffusely hyperplasic, due to Cushing's syndrome. The patient was treated with a surgical wedge resection. The histopathological diagnosis confirmed that the tumour was a grade 1 well-differentiated neuroendocrine carcinoma.

Kara Leonard

2013-04-01

Full Text Available Membranous glomerulonephritis can occur as a rare paraneoplastic complication of human cancers. In this case report, we describe a patient who presented acutely with symptoms of the nephrotic syndrome including heavy proteinuria and anasarca. He was subsequently diagnosed with membranous glomerulonephritis, and soon afterwards was found to have stage IIIB non-small cell lung cancer. Following chemoradiation therapy, both the patient’s cancer and membranous glomerulonephritis dramatically improved. However, approximately 14 months following his initial presentation, the patient was found to have a recurrence of his nephrotic-range proteinuria which corresponded temporally with recurrence of his cancer. We present details of the case and a review of the relevant scientific literature.

Whole-exome sequencing was used to identify the disease gene(s) in a Spanish girl with failure to thrive, muscle weakness, mild facial weakness, elevated creatine kinase, deficiency of mitochondrial complex III and depletion of mtDNA. With whole-exome sequencing data, it was possible to get the whole mtDNA sequencing and discard any pathogenic variant in this genome. The analysis of whole exome uncovered a homozygous pathogenic mutation in thymidine kinase 2 gene ( TK2; NM_004614.4:c.323 C>T, p.T108M). TK2 mutations have been identified mainly in patients with the myopathic form of mtDNA depletion syndromes. This patient presents an atypical TK2-related myopathic form of mtDNA depletion syndromes, because despite having a very low content of mtDNA (TK2 gene in mtDNA depletion syndromes and expanded the phenotypic spectrum.

Full Text Available Objective: Ishemic bone disease has multifactorial etiologies. Cronic dental infections should be eliminated to prevent osteonecrosis of the jaw. Case report: We report an unusual case of osteonecrosis due to the pulpal-peridontal syndrome and subsequent pulp necrosis. A case of 38 year old woman who presented with exposed bone, 8 mm in diameter, in the lingual area of the right lower third molar. The patient was otherwise healthy and was not taking any medications. A detailed medical history showed no previous diseases. Patient denied any type of local trauma. A complete blood count showed no abnormalities. The panoramic radiograph revealed a deep periodontal pocket between teeth 47 and 48. The CBCT revealed a deep periodontal pocket between molars and bone sequestrum of the lingual plate. Topical treatment consisted of adhesive periodontal dressing based on the cellulose and betamethasone oitnment together with orabase, without improvement. Therefore, peroral amoxycillin was prescribed for a week. Since there was no improvement, the third molar was removed as well as necrotic bone; the alveolar bone was remodelled and utures were placed. After suturing, the whole area was covered using intraoral resorbable bandage. Microbial swab of the wound aspirate did not reveal polymorphonuclears or the presence of icroorganisms. Microbial swab of the biopsy specimen of the necrotic bone particle and sequestrum showed a large amount of gram-positive coccae, however, polymorphonuclears were not found. Histopathological analysis revealed acute chronic inflammation. One week after the surgery, the area healed completely. Conclusion: This case highlights the fact that in some patients bone exposure might develop due to the pulpal-peridontal syndrome i.e. pulp necrosis.

Full Text Available Plasmodium malariae is a slow-growing parasite with a wide geographic distribution. Although generally regarded as a benign cause of malaria, it has been associated with nephrotic syndrome, particularly in young children, and can persist in the host for years. Morbidity associated with P. malariae infection has received relatively little attention, and the risk of P. malariae-associated nephrotic syndrome is unknown.We used data from a very large hospital-based surveillance system incorporating information on clinical diagnoses, blood cell parameters and treatment to describe the demographic distribution, morbidity and mortality associated with P. malariae infection in southern Papua, Indonesia. Between April 2004 and December 2013 there were 1,054,674 patient presentations to Mitra Masyarakat Hospital of which 196,380 (18.6% were associated with malaria and 5,097 were with P. malariae infection (constituting 2.6% of all malaria cases. The proportion of malaria cases attributable to P. malariae increased with age from 0.9% for patients under one year old to 3.1% for patients older than 15 years. Overall, 8.5% of patients with P. malariae infection required admission to hospital and the median length of stay for these patients was 2.5 days (Interquartile Range: 2.0-4.0 days. Patients with P. malariae infection had a lower mean hemoglobin concentration (9.0 g/dL than patients with P. falciparum (9.5 g/dL, P. vivax (9.6g/dL and mixed species infections (9.3g/dL. There were four cases of nephrotic syndrome recorded in patients with P. malariae infection, three of which were in children younger than 5 years old, giving a risk in this age group of 0.47% (95% Confidence Interval; 0.10% to 1.4%. Overall, 2.4% (n = 16 of patients hospitalized with P. malariae infection subsequently died in hospital, similar to the proportions for the other endemic Plasmodium species (range: 0% for P. ovale to 1.6% for P. falciparum.Plasmodium malariae infection is

Full Text Available We present the first case of small cell lung cancer with Lambert-Eaton myasthenic syndrome during hemodialysis (HD. A 72-year-old male patient receiving HD experienced progressive muscle weakness. He was diagnosed with small cell lung cancer with Lambert-Eaton myasthenic syndrome due to an increased serum level of anti-voltage-gated calcium channel antibody and aspiration cytology on endobronchial ultrasonography for the swelling of a subcarinal lymph node. He received chemotherapy consisting of carboplatin (300 mg/m2 and etoposide (50 mg/m2, to which he had a partial response. However, the second therapy course could not be administered because of the unexpected development of severe hematological adverse events, which also prevented him from undergoing further HD. This case indicates that caution should be taken when using chemotherapy for such patients because of hypotension due to chemotherapy, with which it is impossible to undergo HD.

Hereditary mixed polyposis syndrome due to a BMPR1A mutation.

The conditions Juvenile Polyposis Syndrome (JPS) and Hereditary Mixed Polyposis Syndrome (HMPS) are associated with an increased risk of colorectal carcinoma. The genetic mechanisms which explain these conditions have until recently been poorly understood. Recent interest has focused on the transforming growth factor (TGF)-beta signalling pathway and, in particular, on mutations in the SMAD4 gene. However, not all cases of JPS and HMPS have mutations in SMAD4 and focus has now shifted to other components of the TGF-beta pathway to clarify the genetic mechanisms involved in these conditions. In this report, we describe the significance of a bone morphogenetic protein receptor type 1A gene mutation in an Irish family.

Full Text Available Neuropsychiatric symptoms in Alzheimer’s disease (AD are prevalent, however their relationship with patterns of cortical atrophy is not fully known. Objectives To compare cortical atrophy’s patterns between AD patients and healthy controls; to verify correlations between neuropsychiatric syndromes and cortical atrophy. Method 33 AD patients were examined by Neuropsychiatric Inventory (NPI. Patients and 29 controls underwent a 3T MRI scanning. We considered four NPI syndromes: affective, apathy, hyperactivity and psychosis. Correlations between structural imaging and neuropsychiatric scores were performed by Freesurfer. Results were significant with a p-value < 0.05, corrected for multiple comparisons. Results Patients exhibited atrophy in entorhinal cortices, left inferior and middle temporal gyri, and precuneus bilaterally. There was correlation between affective syndrome and cortical thickness in right frontal structures, insula and temporal pole. Conclusion Cortical thickness measures revealed atrophy in mild AD. Depression and anxiety symptoms were associated with atrophy of right frontal, temporal and insular cortices.

Full Text Available Background: Treacher-Collins syndrome is a congenital craniofacial disorder with multiple anomalies. This syndrome affects the maxilla, mandible, eyes, middle and outer ears, and soft palate. Conductive hearing loss due to the deformities of the middle and external ears is prevalent. The characteristics of this syndrome include multiple and serious threats to normal communication development in children. In this study, speech and language features of a Persian speaking child with this syndrome are presented.Case: The case was an 8-year old girl with Treacher-Collins syndrome and bilateral moderate conductive hearing loss due to atretic canal. In language and speech assessments, moderate hypernasality, numerous compensatory errors and morphosyntactic deficits were observed. There were 13 phonemes that were incorrectly produced at least in one position. Besides, she used 22 types of phonological processes that were abnormal and disappear before the age of three in normal Persian speaking children.Conclusion: Moderate hearing loss, velopharyngeal incompetency, malocclusion and dental anomalies, attention deficit/hyperactivity disorder (ADHD and environmental factors resulted in severe speech and language disorders in this case. These disorders affected her academic performance as well. Moderate hypernasality, numerous compensatory errors, and excessive and abnormal use of phonological processes were not presented as prevalent characteristics of Treacher-Collins syndrome in other resources.

2006-01-01

We present a rare case of bilateral crocodile tears syndrome (CTS) in the course of Melkersson-Rosenthal syndrome. Melkersson-Rosenthal syndrome is characterised by a triad of recurrent orofacial swelling, relapsing facial paralysis, and fissured tongue. The classic triad is infrequent and oligosymptomatic variants are seen more frequently. CTS is a rare complication of facial nerve paralysis characterised by inappropriate lacrimation on the side of the palsy in response to salivary stimuli. It results from aberrant reinnervation of the lacrimal gland by salivary parasympathetic fibres. The therapeutic approach for an acute bout of Melkersson-Rosenthal syndrome consists mainly of steroid administration. CTS management is composed of anticholinergic drugs and surgical procedures. Botulin toxin injection into the lacrimal gland is the most modern therapeutic option. In the case presented CTS developed in a 50-year-old man after 5 incidents of facial palsy due to Melkersson-Rosenthal syndrome. The case deserves attention due to the rarity of the observed symptoms and signs.

2013-01-01

Full Text Available Hymenoptera stings are self-limiting events or due to allergic reactions. Sometimes envenomation with Hymenoptera can cause rare complications such as acute encephalopathy, peripheral neuritis, acute renal failure, nephrotic syndrome, silent myocardial infarction, rhabdomyolysis, conjunctivitis, corneal infiltration, lens subluxation, and optic neuropathy. The mechanism of peripheral nervous system damage is not clearly known. In our studied case after bee sting on face between the eyebrows with little erythema and  cm in size, bilateral blindness developed and gradually improved. Lateral movement of eyes was restricted with no pain. Involvement of cranial nerves including II, V, and VI was found. With conservative therapy after a year significant improvement has been achieved.

2015-09-04

Diencephalic Syndrome is a rare clinical condition of failure to thrive despite a normal caloric intake, hyperalertness, hyperkinesis, and euphoria usually associated with low-grade hypothalamic astrocytomas. We reported an unusual case of diencephalic cachexia due to hypothalamic anaplastic astrocytoma (WHO-grade III). Baseline endocrine function evaluation was performed in this patient before surgery. After histological diagnosis, he enrolled to a chemotherapy program with sequential high-dose chemotherapy followed by hematopoietic stem cell rescue. The last MRI evaluation showed a good response. The patient is still alive with good visual function 21 months after starting chemotherapy. Diencephalic cachexia can rarely be due to high-grade hypothalamic astrocytoma. We suggest that a nutritional support with chemotherapy given to high doses without radiotherapy could be an effective strategy for treatment of a poor-prognosis disease.

Eagle syndrome

Raina, Deepika; Gothi, Rajesh; Rajan, Sriram

2009-01-01

Eagle syndrome occurs due to elongation of the styloid process or calcification of the stylohyoid ligament, which then may produce a pain sensation due the pressure exerted on various structures in the head and neck. When suspected, imaging helps in identifying the abnormally elongated styloid process or the calcified ligament. In recent years, three-dimensional CT (3DCT) has proved to be valuable in these cases. We report the case of a 62-year-old man with this syndrome in whom imaging with 3DCT conclusively established the diagnosis

A 34-year-old male patient complained of general fatigue, ascites, and edema of the lower extremities. A chest x-ray film showed atelectasis of the right lung and pleural effusion of the right side. Liver ultrasonography revealed stenosis of the middle and right hepatic veins. Venacavography revealed stenosis of the inferior vena cava and collateral circulation. Finally, abdominal NMR-CT clearly visualized lunate stenosis and antero-lateral deviation of the inferior vena cava. He was diagnosed as having secondary Budd-Chiari syndrome resulting from the deviation and stenosis of the inferior vena cava due to distortion of the surrounding tissues by the thickened pleura which was caused by chronic empyema.

2014-06-01

Metabolic syndrome is an increasing pathology in adults and in children, due to a parallel rise of obesity. Sedentary lifestyle, food habits, cultural influences and also a genetic predisposition can cause dyslipidemia, hypertension, abdominal obesity and insulin resistance which are the two main features of metabolic syndrome. Polycystic ovary syndrome (PCOS) is a condition directly associated with obesity, insulin resistance (HOMA index) and metabolic syndrome, and it is very interesting for its relationship and overlap with the metabolic syndrome. The relationship between the two syndromes is mutual: PCOS women have a higher prevalence of metabolic syndrome and also women with metabolic syndrome commonly present the reproductive/endocrine trait of PCOS. Prevention and treatment of metabolic syndrome and PCOS are similar for various aspects. It is necessary to treat excess adiposity and insulin resistance, with the overall goals of preventing cardiovascular disease and type 2 diabetes and improving reproductive failure in young women with PCOS. First of all, lifestyle changes, then pharmacological therapy, bariatric surgery and laparoscopic ovarian surgery represent the pillars for PCOS treatment.

Although the clinical phenotype of Lynch syndrome (also known as hereditary nonpolyposis colorectal cancer) has been well described, little is known about disease in PMS2 mutation carriers. Now that mutation detection methods can discern mutations in PMS2 from mutations in its pseudogenes, more mutation carriers have been identified. Information about the clinical significance of PMS2 mutations is crucial for appropriate counseling. Here, we report the clinical characteristics of a large series of PMS2 mutation carriers. We performed PMS2 mutation analysis using long-range polymerase chain reaction and multiplex ligation-dependent probe amplification for 99 probands diagnosed with Lynch syndrome-associated tumors showing isolated loss of PMS2 by immunohistochemistry. Penetrance was calculated using a modified segregation analysis adjusting for ascertainment. Germ-line PMS2 mutations were detected in 62% of probands (n = 55 monoallelic; 6 biallelic). Among families with monoallelic PMS2 mutations, 65.5% met revised Bethesda guidelines. Compared with the general population, in mutation carriers, the incidence of colorectal cancer was 5.2-fold higher, and the incidence of endometrial cancer was 7.5-fold higher. In North America, this translates to a cumulative cancer risk to age 70 years of 15%-20% for colorectal cancer, 15% for endometrial cancer, and 25%-32% for any Lynch syndrome-associated cancer. No elevated risk for non-Lynch syndrome-associated cancers was observed. PMS2 mutations contribute significantly to Lynch syndrome, but the penetrance for monoallelic mutation carriers appears to be lower than that for the other mismatch repair genes. Modified counseling and cancer surveillance guidelines for PMS2 mutation carriers are proposed.

C1q Nephropathy: The Unique Underrecognized Pathological Entity

Directory of Open Access Journals (Sweden)

Joe Devasahayam

2015-01-01

Full Text Available C1q nephropathy is a rare glomerular disease with characteristic mesangial C1q deposition noted on immunofluorescence microscopy. It is histologically defined and poorly understood. Light microscopic features are heterogeneous and comprise minimal change disease (MCD, focal segmental glomerulosclerosis (FSGS, and proliferative glomerulonephritis. Clinical presentation is also diverse, and ranges from asymptomatic hematuria or proteinuria to frank nephritic or nephrotic syndrome in both children and adults. Hypertension and renal insufficiency at the time of diagnosis are common findings. Optimal treatment is not clear and is usually guided by the underlying light microscopic lesion. Corticosteroids are the mainstay of treatment, with immunosuppressive agents reserved for steroid resistant cases. The presence of nephrotic syndrome and FSGS appear to predict adverse outcomes as opposed to favorable outcomes in those with MCD. Further research is needed to establish C1q nephropathy as a universally recognized distinct clinical entity. In this paper, we discuss the current understanding of pathogenesis, histopathology, clinical features, therapeutic options, and outcomes of C1q nephropathy.

We report a case of flexion contractures in a patient's legs secondary to postpartum hypopituitarism. A 56-year-old woman presented with a 3-year history of worsening flexion contractures of the hips and knees. On admission, her hips and knees could not be extended, and she had muscle stiffness and tenderness to palpation of the lower extremities. We first suspected stiff-person syndrome or Isaacs' syndrome because of her muscle stiffness. However, multiple hormones did not respond to stimulation tests, and an MRI of the brain showed atrophy of the pituitary gland with an empty sella. A subsequent interview revealed that she had suffered a severe hemorrhage while delivering her third child. She was diagnosed with panhypopituitarism and started on cortisol replacement therapy. After 1 week of treatment with hydrocortisone (10 mg/day), her symptoms quickly improved. We then added 75 μg/day of thyroid hormone. During the course of her treatment, autoantibodies against VGKC complex were found to be weakly positive. However, we considered the antibodies to be unrelated to her disease, because her symptoms improved markedly with low-dose steroid treatment. There are a few reports describing flexion contractures of the legs in patients with primary and secondary adrenal insufficiency. As these symptoms are similar to those seen in stiff-person syndrome, adrenal and pituitary insufficiency should be taken into account to achieve the correct diagnosis and treatment in patients with flexion contractures and muscle stiffness.

Wolff-Parkinson-White syndrome and noncompaction in Leber's hereditary optic neuropathy due to the variant m.3460G>A.

Finsterer, Josef; Stollberger, Claudia; Gatterer, Edmund

2018-05-01

This report describes a 66-year-old Caucasian male who acutely developed severe, bilateral impairment of visual acuity at 24 years of age. Leber's hereditary optic neuropathy (LHON) was suspected but the diagnosis was not genetically confirmed until the age of 49 years when the primary LHON mutation m.3460G>A was detected. Since onset, visual acuity had slightly improved. The family history was positive for LHON (brother, two sisters of mother, female cousin) and genetically confirmed in his brother and one aunt. Since the age of 65 years, he had experienced recurrent vertigo. His cardiological history was positive for arterial hypertension, noncompaction, myocardial thickening, intermittent right bundle-branch-block (RBBB) and Wolff-Parkinson-White (WPW) syndrome. In addition to LHON, he presented with polyneuropathy, hyperCKaemia, carotid artery occlusion, and a history of stroke. Cardiological investigations at 66 years of age revealed mildly reduced systolic function, enlarged atria, and nonsustained ventricular tachycardias. He underwent an electrophysiological investigation, but radiofrequency ablation was ruled out due to a 'bizarre' cardiac conduction system. Instead, an implantable cardioverter defibrillator was proposed but refused by the patient. Since the vertigo did not resolve it was attributed to polyneuropathy. This case demonstrates that LHON may be associated with noncompaction, myocardial thickening, reduced systolic function, enlarged atria, RBBB, WPW syndrome and nonsustained ventricular tachycardias. WPW syndrome in LHON may require invasive antiarrhythmic treatment.

Full Text Available The Gorlin-Goltz syndrome (GGS (the nevoid basal cell carcinoma syndrome—NBCCS is a rare autosomal dominant syndrome caused due to mutations in the PTCH (patched gene found on chromosome arm 9q. The syndrome, characterized by increased predisposition to develop basal cell carcinoma and associated multiorgan anomalies, has a high level of penetrance and variable expressiveness. GGS is a multidisciplinary problem, early diagnosis of which allows introduction of secondary prophylaxis and following an appropriate treatment to delay the progress of the syndrome. The following report emphasizes the need for awareness of the diagnostic criteria of this syndrome in cases with no typical skin lesions.

The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome-NBCCS) is an autosomal dominant syndrome caused by mutations found on chromosome 9. The syndrome is characterized by increased predisposition to develop a basal cell carcinoma and associated with multiorgan anomalies. To present a case of GGS and explain modern standards of care for patients with this syndrome. Authors report the case of a 36-year-old patient who was admitted to the Plastic Surgery Clinic due to numerous basal cell carcinomas. Previously patient underwent an orthopaedic, neurologic, dermatologic, stomatologic and surgery treatment due to particular anomalies which characterize this syndrome. Comprehensive interview and broadening of the diagnostics enabled to diagnose GGS and to introduce the appropriate treatment. GGS is a multidisciplinary problem and widespread knowledge of this syndrome could accelerate the diagnosis process. Early diagnosis of GGS allows to introduce the secondary prophylaxis and to apply the appropriate treatment to slow the progress of the syndrome.

2015-01-01

Insulin resistance syndromes without lipodystrophy are an infrequent and heterogeneous group of disorders with variable clinical phenotypes, associated with hyperglycemia and hyperinsulinemia. The three conditions related to mutations in the insulin receptor gene are leprechaunism or Donohue syndrome, Rabson-Mendenhall syndrome, and Type A syndrome. A case is presented on a patient diagnosed with type A insulin resistance, defined by the triad of extreme insulin resistance, acanthosis nigricans, and hyperandrogenism, carrying a heterozygous mutation in exon 19 of the insulin receptor gene coding for its tyrosine kinase domain that is crucial for the catalytic activity of the receptor. The molecular basis of the syndrome is reviewed, focusing on the structure-function relationships of the insulin receptor, knowing that the criteria for survival are linked to residual insulin receptor function. It is also pointed out that, although type A insulin resistance appears to represent a somewhat less severe condition, these patients have a high morbidity and their treatment is still unsatisfactory.

Williams-Beuren syndrome (WBS) is a relatively common, clinically recognizable microdeletion syndrome. In most cases the typical heterozygous deletion of 1.5 Mb on chromosome 7q11.23 spanning about 26 genes can be identified. Also some larger or smaller atypical deletions have been reported and associated with additional or atypical phenotypic aspects. We report on an individual with typical WBS due to the common deletion and with refractory infantile spasms. Using trio-exome sequencing, we identified a de novo truncating variant c.1200del, p (Lys401Serfs*25) in GABRA1 as the likely cause of the early onset epilepsy. This unique case not only allows to further define the phenotypic spectrum of infantile epileptic encephalopathy associated with rare de novo GABRA1 variants but exemplifies the need for a sensitive review of unclear associations in clinically defined syndromes and for extended diagnostic work-up in individuals with unusual presentations of a genetically confirmed diagnosis.

Two pairs of siblings are described with proportionate dwarfism due to skeletal hypoplasia of prenatal onset. The head size was normal for age and disproportionately large for height. The patients had a characteristic face different from that seen in the Silver-Russell syndrome. The family data are in accordance with autosomal recessive inheritance. In spite of some similarities, the bulk of clinical and genetic evidence suggests that the described intrauterine growth retardation syndrome is different from the Silver-Russell syndrome and presents an apparently "new" entity which has been designated 3-M syndrome.

Incidence of falciparum malaria in developed countries has increased in recent years due to tourism to tropical countries and immigration from Asia and Africa. In Switzerland, about 250 cases of malaria were reported in 1994 to the Federal Office of Health, including three cases with fatal outcome.1 The most commonly described complications of plasmodia infection are cerebral malaria, acute renal failure, and severe anemia with disseminated intravascular coagulation. However, pulmonary involvement occurs in 3 to 10% of cases and represents the most serious complication of this infection, with a lethality of 70%.2,3 Furthermore, a pronounced general immunosuppression has been reported in malaria patients, which may predispose them to opportunistic infections.4 We report a case of Plasmodium falciparum infection complicated by severe acute respiratory distress syndrome (ARDS) with development of systemic cytomegalovirus (CMV) infection leading to death. This evolution implies a severe immune deficiency associated with malaria, as previously suggested in the literature.

Hyperthyroidism with the syndrome of inappropriate secretion of TSH (SITSH) occurred by a decrease in hydrocortisone dose after surgery for Cushing's syndrome. This is a novel cause of SITSH. The aim of this study was to describe and discuss 2 cases of SITSH patients that were found after surgery for Cushing's syndrome. We also checked whether SITSH occurred in 7 consecutive patients with Cushing's syndrome after surgery. A 45-year-old Japanese woman with ACTH-independent Cushing's syndrome and a 37-year-old Japanese man with ACTH-dependent Cushing's syndrome presented SITSH caused by insufficient replacement of hydrocortisone for postoperative adrenal insufficiency. When the dose of hydrocortisone was reduced to less than 20 mg/d within 18 days after surgery, SITSH occurred in both cases. We examined whether the change of the hydrocortisone dose induced the secretion of TSH. Free T₃ and TSH were normalized by the hydrocortisone dose increase of 30 mg/d, and these were elevated by the dose decrease of 10 mg/d. We also checked TSH and thyroid hormone levels of the 7 consecutive patients with Cushing's syndrome after surgery. Six (66.6 %) of 9 patients showed SITSH. This is the first report that insufficient replacement of hydrocortisone after surgery for Cushing's syndrome caused SITSH. Hyperthyroidism by SITSH as well as adrenal insufficiency can contribute to withdrawal symptoms of hydrocortisone replacement. We need to consider the possibility of SITSH for the pathological evaluation of withdrawal syndrome of hydrocortisone replacement.

Full Text Available Background: Snakebite is a health issue specific to some parts of the world, especially in the tropical area, where it produces many victims. The main clinical damage caused by snake bite involves hemotoxic, neurotoxic and myotoxic reactions. It is also established that the importance of systemic impairment varies according to individual factors and are related to organ dysfunction, shock or hypotension. We report the case of a young woman suffering from snakebite who developed deep vein thrombosis and compartment syndrome. Case Report: We present the case of a 32-year-old Romanian woman who was injured by her own Crotalinae snake (also known as pit viper or rattlesnake on her left forearm. When admitted to our Emergency Department, she was conscious with a Glasgow coma scale of 12/15, somnolent, febrile, suffering of headache, tachypnea; the marks of the snakebite were located in the distal part of the anterior left forearm; she had pain and bleeding at the bite site and swelling of the left upper limb with lymphangitis up to the axilla. She experienced fasciotomy-requiring compartment syndrome of the upper limb and required unfractionated heparin and closed monitored using activated partial thromboplastin time evolution due micro-thrombosis in the brachial vein. Local improvement was achieved in the next 4 days with progressive diminish of local tenderness and swelling. Conclusion: Limb deep vein thrombosis might be induced by snakebite, despite pro-hemorrhagic general condition induced by the envenomation. High index of clinical suspicion is needed for early diagnosis and timely management which can improve survival of these patients

Renal failure due to primary amyloidosis: a case report and literature review

Full Text Available CONTEXT: Primary amyloidosis, also known as AL amyloidosis, is commonly caused by clonal expansion of plasma cells in the bone marrow, thereby segregating light chains of clonal immunoglobulin that settle in tissues in the form of insoluble amyloid fibrils. The aim of this study was to report a case of primary amyloidosis with renal failure, diagnosed in Hospital São João, Porto, Portugal, focusing on the diagnostic difficulties and presenting a literature review. CASE REPORT: A 68-year-old Caucasian man was admitted to the Internal Medicine Department of the hospital with a condition of anasarca and nephrotic syndrome. After performing a renal biopsy that tested positive using Congo red and immunohistochemistry, lambda light chain amyloidosis was diagnosed. This evolved into terminal renal disease, which led to hemodialysis and several episodes of urinary and catheter infections. He was started on chemotherapy, consisting of bortezomib 0.7 mg/m² and dexamethasone 40 mg in six cycles. This led to clinical improvement, stabilization of the illness and good tolerance of the treatment. CONCLUSION: Amyloidosis is a rare entity that is difficult to diagnose. This is because of the unspecific early clinical manifestations of the disease. The hypothesis of amyloidosis is only considered when specific organ failure occurs. This case consisted of primary amyloidosis with involvement of the kidneys as an initial presentation of the disease and its difficulties were shown, going from the clinical approach to the final diagnosis.

Our objective was to evaluate efficacy and patency of metallic stent placement for symptomatic Budd-Chiari syndrome (BCS) due to prothrombotic disorders. Eleven patients with proved BCS due to prothrombotic disorders were referred for endovascular treatment because of refractory ascites (n=9), abdominal pain (n=8), jaundice (n=6), and/or gastrointestinal bleeding (n=4). Stents were inserted for stenosed hepatic vein (n=7), inferior vena cava (n=2), or mesenterico-caval shunt (n=2). Clinical efficacy and stent patency was evaluated by clinical and Doppler follow-up. After a mean follow-up of 21 months, 6 patients had fully patent stents without reintervention (primary stent patency: 55%). Two patients with hepatic vein stenosis had stent thrombosis and died 4 months after procedure. Restenosis occurred in 3 cases (2 hepatic vein and 1 mesenterico-caval shunt stenosis) and were successfully treated by balloon angioplasty (n=2) and addition of new stents (n=1) leading to a 82% secondary stent patency. Of 9 patients with patent stent, 7 were asymptomatic (77%) at the end of the study. Stent placement is a safe and effective procedure to control of symptomatic BCS. Prothrombotic disorder does not seem to jeopardize patency in anticoagulated patients. (orig.)
