    Drug-induced acute interstitial nephritis is a well-recognised and important reversible cause of acute renal failure. Peroxisome-proliferator activated receptor-gamma agonists, such as rosiglitazone, have been proven to be safe in chronic kidney disease patients. We describe a 65-year-old man with long-standing diabetes mellitus and hypertension, presenting with a five-day history of fluid overload and uraemic symptoms. There was no ingestion of analgesics, alternative medicine and other nephrotoxic drugs, the only new prescription being rosiglitazone, which was commenced during his last clinic follow-up two weeks prior to presentation. He required haemodialysis with minimal improvement in renal profile, despite cessation of the offending drug. Renal biopsy revealed findings consistent with acute interstitial nephritis. An episode of upper gastrointestinal bleeding with bleeding duodenal ulcer limited the use of steroids. He was treated with a course of mycophenolate mofetil which showed good gradual response and he remained stable with residual renal impairment.

    A 46-year-old man with end-stage renal disease and renal cell carcinoma underwent F-FDG PET/CT for initial staging followed by F-PSMA-1007 PET/CT. Unlike F-FDG, which undergoes renal clearance, F-PSMA-1007 undergoes hepatobiliary clearance and thus generates superior quality images. F-PSMA-1007 PET/CT showed intense tracer-avid left renal mass lesion (FDG nonavid); lytic bone lesions (FDG avid) and single liver lesion (FDG nonavid). This case highlights the superiority of F-PSMA-1007 over F-FDG PET/CT in identifying primary lesion as well as metastatic sites in case of renal cell carcinoma even in the presence of end-stage renal disease.

    Octylphenol (OP) is one of ubiquitous pollutants in the environment. It belongs to endocrine-disrupting chemicals (EDC). It is used in many industrial and agricultural products. Pectin is a family of complex polysaccharides that function as a hydrating agent and cementing material for the cellulose network. The aim of this study was to evaluate the therapeutic effect of pectin in kidney dysfunction, oxidative stress and apoptosis induced by OP exposure. Thirty-two male albino rats were divided into four equal groups; group 1 control was injected intraperitoneally (i.p) with saline [1 ml/kg body weight (bwt)], groups 2, 3 & 4 were injected i.p with OP (50 mg/kg bwt) three days/week over two weeks period where groups 3 & 4 were injected i.p with pectin (25 or 50 mg/kg bwt) three days/week over three weeks period. The results of the present study revealed that OP significantly decreased glutathione-S-transferase (GST), glutathione peroxidase (GPx), catalase (CAT), reduced glutathione (GSH), glutathione reductase (GR) and superoxide dismutase (SOD) levels while increased significantly lipid peroxidation (MDA), nitric oxide (NO) and protein carbonyls (PC) levels in the kidney tissues. On the other hand, OP increased serum urea and creatinine. Furthermore, OP increased significantly serum uric acid but decreased significantly the kidney weight. Moreover, OP decreased p53 expression while increased bcl-2 expression in the kidney tissue. The treatment with either dose of pectin to OP-exposed rats restores all the above parameters to approach the normal values where pectin at higher dose was more effective than lower one. These results were supported by histopathological investigations. In conclusion, pectin has antioxidant and anti-apoptotic activities in kidney toxicity induced by OP and the effect was dose-dependent.

    This study investigated the pretreatment and post-treatment effects of dipyridamole (20 mg/kg/day, p.o.) in gentamicin-induced acute nephrotoxicity in rats. Rats were administered gentamicin (100 mg/kg/day, i.p.) for 8 days. Gentamicin-administered rats exhibited renal structural and functional changes as assessed in terms of a significant increase in serum creatinine and urea and kidney weight to body weight ratio as compared to normal rats. Renal histopathological studies revealed a marked incidence of acute tubular necrosis in gentamicin-administered rats. These renal structural and functional abnormalities in gentamicin-administered rats were accompanied with elevated serum uric acid level, and renal inflammation as assessed in terms of decrease in interleukin-10 levels. Dipyridamole pretreatment in gentamicin-administered rats afforded a noticeable renoprotection by markedly preventing renal structural and functional abnormalities, renal inflammation and serum uric acid elevation. On the other hand, dipyridamole post-treatment did not significantly prevent uric acid elevation and renal inflammation, and resulted in comparatively less protection on renal function although it markedly reduced the incidence of tubular necrosis. In conclusion, uric acid elevation and renal inflammation could play key roles in gentamicin-nephrotoxicity. Dipyridamole pretreatment markedly prevented gentamicin-induced acute nephrotoxicity, while its post-treatment resulted in comparatively less renal functional protection.

    Rheumatoid arthritis in HIV patients undergoing HAART is associated with increased risk of side effect. Elevation of uric acid (UA) is important in tissue damage, deposition of crystal in joints leads to the development of rheumatoid arthritis in the HAART complaint group. This study was carried out to investigate the relationship of uric acid, RA factor, ANA, ESR, cystatin C, urea and creatinine in the HAART complaint group. Moreover; the ratio of uric acid/cystatin C, uric acid/urea and uric acid/creatinine were also studied. To analyze the progression of HIV, the immunological parameters were correlated with uric acid. Our result showed a statistically high significant increase in uric acid, RA factor, ANA, ESR, cystatin C, urea and creatinine in the HAART complaint group when compared to HAART non-complaint group, early stage and control. The ratio of uric acid/cystatin C, uric acid/urea, uric acid/creatinine were significantly increased in the HAART complaint group. Statistically significant positive correlation was observed between uric acid and cystatin C, urea, creatinine, absolute CD4 and CD8 count. The increased level of uric acid, RA factor, ANA, ESR, cystatin C and increased ratio of uric acid/cystatin C in the HAART complaint group might conclude the mechanism underlying the increased risk for rheumatoid arthritis in the HAART complaint group which may relate to the combined effects of low-grade inflammation and renal dysfunction.

    BACKGROUND: The psychosocial impact of living with autosomal dominant polycystic kidney disease (ADPKD) is poorly understood. In this study, we assessed the overall quality of life (QOL), mood, perceived social support and psychosocial risk of having a diagnosis of ADPKD in a patient cohort from a major UK nephrology centre serving a large catchment population.

    METHODS: A postal questionnaire was sent to 349 patients registered at the Sheffield Kidney Institute with chronic kidney disease but not on renal replacement therapy (RRT). The questionnaire incorporated three validated forms: kidney disease quality-of-life short form (KDQOL SF1.3) to assess QOL; nine-item patient health questionnaire (PHQ9) to screen for depression; multidimensional scale of perceived social support (MSPSS) to evaluate perceived social support; as well as a novel genetic psychosocial risk instrument (GPRI-ADPKD) designed to study the specific psychosocial impact of coping with a diagnosis of ADPKD.

    RESULTS: The overall response rate was 53%. Patients with a lower estimated glomerular filtration rate (<30 mL/min) or larger kidneys (mean length on ultrasound ≥17 cm) reported reduced QOL and increased psychosocial risk. Clinically significant depression was reported in 22% and 62% felt guilty about passing ADPKD on to their children. In multivariate analysis, female gender was associated with overall poorer psychosocial well-being, whereas increasing age, lower kidney function, larger kidneys and loss of a first degree relative from ADPKD were additional risk factors for QOL, depression or psychosocial risk, respectively.

    CONCLUSIONS: Our results reveal a significantly poorer QOL and increasing psychosocial risk with markers of disease progression in patients, particularly women, with ADPKD prior to starting RRT. The future management strategy of ADPKD should address these issues and provide for better individual and family support throughout the patient journey.

    One of the challenges in differentiating chromophobe renal cell carcinoma (chRCC) from benign renal oncocytoma (RO) is overlapping morphology between the two subtypes. The aim of this study was to investigate the usefulness of expression of leptin (Ob) and its receptor (ObR) in discriminating chRCC from RO. Sections from paraffin-embedded, formalin-fixed tumour nephrectomy specimens of 45 patients, made up of 30 chRCC (15 eosinophilic variant and 15 non-eosinophilic variant) and 15 RO, were used in this study. Samples (30) of clear cell RCC (ccRCC), the most common histological subtype, were used to verify staining patterns found by others in our cohort of Australasian patients. Matched morphologically normal non-cancer kidney tissues were included for each specimen. Sections were batch-immunostained using antibodies against Ob and ObR. Stained sections were digitally scanned using Aperio ImageScope, and the expression pattern of Ob and ObR was studied. In this cohort, male to female ratio was 2:1; median age was 64 (45-88 years); and median tumour size was 3.8 cm (range 1.2-18 cm). There were 47 (62.7%) T1, seven T2, 20 T3 and one T4 stage RCC. Two patients with ccRCC presented with metastases. Nuclear expression of Ob was significantly higher in RO compared with chRCC. The increased nuclear expression of Ob in RO compared with chRCC may be a useful aid in the difficult histological differentiation of RO from chRCC, especially eosinophilic variants of chRCC.

    Paroxysmal nocturnal haemoglobinuria (PNH) also known as 'Marchiafava Micheli syndrome' is a rare condition which can lead to both acute and chronic forms of renal failure through renal tubular haemosiderin deposition. A 45-year-old lady with underlying PNH, presented with complaints of fever, productive cough followed by dark coloured urine. Investigations revealed pancytopenia with a markedly raised creatinine from her baseline (from 65 mmol/L to 385 mmol/L) consistent with acute kidney injury (AKI). Renal biopsy confirmed the diagnosis of haeme nephropathy. The renal impairment improved rapidly and normalised over a period of 5 days with alkaline diuresis (AD). The patient did not require haemodialysis unlike most other reported cases of AKI secondary to haeme nephropathy in PNH. This is the second reported case of AKI in PNH which was successfully treated with AD alone emphasizing the role of AD as a promising therapeutic strategy in this condition.

    Variable number of tandem repeats (VNTR) polymorphism in the interleukin 4 (IL-4) gene has been associated with end-stage renal disease (ESRD) subjects in many different populations, although with conflicting results. We determined the 70 bp of VNTR polymorphism at intron 3 of the IL-4 gene in Malaysian ESRD subjects. Buccal cells were collected from 160 case and 160 control subjects; genomic DNA was amplified using PCR, followed by agarose gel electrophoresis. There were significant differences in genotypes and alleles of the IL-4 gene. We conclude that VNTR polymorphism of the IL-4 gene is a risk factor for the development of ESRD among Malaysians.

    Abnormal peritoneal folds near the liver are very rare. This case report presents an observation of an abnormal fold of peritoneum that extended from the upper right part of the greater omentum and stomach to the fossa for gallbladder. This fold merged with the lesser omentum on the left and extended to the right kidney when traced posteriorly. The epiploic foramen was entirely absent due to the presence of this fold. However, the lesser sac was there behind the liver, lesser omentum and stomach. The knowledge of abnormal folds like this may be important for surgeons (Fig. 3, Ref. 7).

    Gastric outlet obstruction and in particular, pyloric stenosis, is relatively common in developing countries. Acute clinical presentation is often the manifestation of biochemical and electrolyte changes. The presence of metabolic alkalosis in combination with acute renal failure should alarm us to the possibility of adult pyloric stenosis. We report a case of adult pyloric stenosis that presented as acute renal failure and discuss its pathophysiology.

    Membranous glomerulonephritis (MGN) is one of the common forms of nephrotic syndrome in the adult population. The majority of MGN are idiopathic, but the secondary forms can be seen in the setting of autoimmune disease, neoplasia, infection and following exposure to certain therapeutic agents. Histologically, MGN is an immunologically mediated disease in which immune complexes deposit in the subepithelial space. Syphilis is a venereal disease that can also be acquired by exposure to infected blood. Untreated syphilis may progress and develop renal complications such as membranous glomerulonephritis (MGN) or diffuse endocapillary glomerulonephritis with or without crescent formation. Today, with increasing awareness of sexually transmitted diseases especially HIV infection coupled by the practice of protected sexual intercourse and advancement of medicine, we have seen fewer and fewer cases of acquired syphilis. Furthermore, majority will present with typical syphilitic symptoms of such as chancre, rash, fever and lymph node enlargement in which case the diagnosis is easily obtained. We are reporting a case of acquired syphilis masquerading as membranous glomerulonephritis without typical syphilitic symptoms.

    Post-transplant lymphoproliferative disorder (PTLD) is a recognized complication exclusive to solid organ transplant recipients and carries a high mortality. We retrospectively reviewed records of all renal transplant recipients under follow up at our institution over the last seven years (2005-2011). We reviewed the patient characteristics, immunosuppression regimen and risk factors for the development of PTLD and its outcomes in our transplant cohort. Four out of 63 patients were diagnosed with PTLD. PTLD was incidentally diagnosed on a transplant biopsy that was performed for an unexplained rise in serum creatinine in three patients. The fourth patient presented with left submandibular lymphadenopathy. Majority presented within 18 months of renal transplantation. After the diagnosis of PTLD on graft biopsy, all patients were fully investigated and two patients had systemic involvement. In the patients with systemic involvement, reduction of immunosuppression and anti B cell therapy with Rituximab was used with good success. The patient with submandibular lymphadenopathy received chemotherapy in addition to reduction of immunosuppression. Three PTLD cases were polyclonal and diagnosed early whereas the fourth case was monoclonal. PTLD can sometimes be incidentally diagnosed on an allograft biopsy performed for rejection. The incidence of PTLD in our centre is higher than reports from other centres but our outcome is good if recognised and treated early.

    Creatinine clearance estimation is widely used to evaluate the renal function of the patients in order to initiate or adjust the drugs dosage. However serum creatinine, as a muscle metabolism by-product, may not be a reliable parameter in underweight and/or non-ambulatory patients, such as geriatric, acquired immunodeficiency syndrome patients and bed-confined and cachexic cases. To avoid overestimation of the renal function in those patients, serum cystatin C can be considered as a sensitive and accurate alternative for serum creatinine.

    There were 72 pregnancies in 46 renal transplants (RTs) between 1984 and 2001, 89% from living donors, 11% cadaveric. Mean age at RT was 26.9 +/- 4.3 years and at pregnancy 30.7 +/- 4.7 years. Mean time to pregnancy after RT was 4.5 +/- 3.1 years. 54% were unplanned. 45 (63%) resulted in surviving infants, 37% delivered by Caesarean section. 35% were premature. Mean birth weight was 2.38 +/- 0.57 kg. 64% were on cyclosporine. No patient had an acute rejection during pregnancy; 38% had pre-existing hypertension. Complications include urinary infection (13%), proteinuria (15%) and preeclampsia (15%). Mean serum creatinine before pregnancy was 112.7 +/- 32.6 umol/l, 1 year post-pregnancy it was 119.4 +/- 38.7. The mean time of follow up of mothers is 4.9 +/- 3.5 years. 10 year graft survival was 83% and patient survival 94%.

    Pros and cons of Percutaneous Nephrolithotripsy (PCNL) versus Extracorporeal Shockwave Lithotripsy (ESWL) have often been highlighted when one discusses on the management of renal stones. An oft quoted point is that PCNL entails a prolonged hospital stay whereas ESWL sessions are day surgical in nature. However, PCNL has superior stone clearance rate as compared to ESWL especially for lower pole stones. In addition, PCNL is more suitable for large bulk stones and when ancillary procedures are required e.g. endopyelotomy. The first 50 cases of successful tubeless PCNL were reported by Bellman et al in 1997. The remarkable recovery of patients in their series encouraged them to employ this technique as their technique of choice for the majority of their cases. A similar technique was employed on endopyelotomy by Liang et al and they concluded that this was a safe, less morbid and effective technique. We report our first case of tubeless PCNL.

    Four cases of emphysematous pyelonephritis are reported and the pathogenesis, surgical implications and preferred mode of management are discussed. We have not found percutaneous drainage to be useful, but feel there is an important place for surgical drainage alone because of the potential for renal recovery and the risks of emergency nephrectomy.
