INTRODUCTION: In recent years, prolonged ketamine abuse has been reported to cause urinary tract damage. However, there is little information on the pathological effects of ketamine from oral administration. We aimed to study the effects of oral ketamine on the urinary tract and the reversibility of these changes after cessation of ketamine intake. METHODS: Rats were fed with illicit (a concoction of street ketamine) ketamine in doses of 100 (N=12), or 300 mg/kg (N=12) for four weeks...

BACKGROUND AND OBJECTIVES: Textbooks and reviews do not mention the association of symptomatic primary Epstein-Barr virus infectious mononucleosis with acute kidney injury in subjects without immunodeficiency or autoimmunity. STUDY DESIGN: Stimulated by our experience with two cases, we performed a review of the literature. RESULTS: The literature documents 38 cases (26 male and 12 female individuals ranging in age from 0.3 to 51, median 18 years) of symptomatic primary Epstein-Barr virus infectious mononucleosis complicated by acute kidney injury: 27 acute interstitial nephritides, 1 jaundice-associated nephropathy, 7 myositides and 3 hemolytic uremic syndromes...

There is paucity of information on the prevalence of leptospirosis in wildlife in Nigeria. This study investigated the prevalence and renal pathology of leptospirosis in wild animals in Southwest Nigeria. One hundred and five kidney samples were examined from 10 different wildlife species (antelope) greater cane rat (GCR), hare, African giant rat (AGR), tree hyrax, civet cat, monitor lizard, python, bushbuck and partridge) using a combination of Ellinghausen McCullough Johnson Harris (EMJH) medium, microscopic agglutination test (MAT), Warthin- Starry silver stain (WSss) and immunohistochemistry...

Background: Differentiating between renal-limited sarcoidosis and tuberculosis (TB) infection as a cause of granulomatous interstitial nephritis (GIN) can be difficult. This series compares clinical features and response to treatment between the different underlying aetiologies in order to propose a management algorithm for GIN to assist with diagnosis and treatment. Methods: This retrospective study reports on all patients presenting with a histological diagnosis of GIN between 2000 and 2012 at our unit. Results: Twenty-one patients were identified, 57% were male and the mean age was 53 years...

Background: Granulomatous interstitial nephritis (GIN) is uncommon in native kidneys, and descriptions in allografts are few. We report clinical and pathologic findings in 22 allograft recipients with GIN identified in renal allograft biopsies and nephrectomies. Methods: Renal allografts with GIN were retrieved from the pathology files of two academic medical centers. Available clinical and pathologic data were compiled retrospectively for a 23-year period. Results: GIN was present in 23 specimens from 22 patients (15 males and 7 females) with allograft dysfunction [serum creatinine averaged 3...

Background: There are no prospective randomized controlled trials describing the outcome of acute interstitial nephritis (AIN) treated with steroids, and retrospective studies are limited. Methods: We identified adult patients with a diagnosis of AIN without glomerular pathology over a 14-year period. Treated patients all received oral prednisolone and three also recieved IV methylprednisolone. Data were collected retrospectively on estimated glomerular filtration rate (eGFR), change in eGFR from time of biopsy, dependence on renal replacement therapy (RRT) and mortality, and outcomes were analysed according to the treatment prescribed...

IgG4 disease is a multi-systemic condition involving pancreas, salivary glands and lymph nodes. Less frequently, it causes interstitial nephritis and involves the lungs. We report a 58 years old male with a four years history of hemoptysis and renal dysfunction characterized by hematuria and proteinuria, responsive to steroidal therapy. The renal biopsy established the diagnosis of IgG4 associated interstitial nephritis. Lung involvement was considered secondary to the same systemic disease.

BACKGROUND: Acute focal bacterial nephritis (AFBN) is a rare disease currently described only in case reports and small case series. In this study we summarize the clinical features of AFBN as has been documented in the literature and draw recommendations on the proper diagnosis and therapy. METHODS: A systematic literature review was undertaken in PUBMED, Web of Science and The Cochrane Library online databases for relevant literature on AFBN in adults. RESULTS: Literature review revealed a total of 38 articles according to our inclusion criteria, of which we could extract data from 138 cases of AFBN...

Hyperkalaemia is often seen in individuals with renal impairment and may be exacerbated, particularly in diabetic nephropathy, by hyporeninaemic aldosterone deficiency (type 4 renal tubular acidosis) which may, in turn, be caused or complicated by chronic interstitial nephritis or drug therapy (Table 1). Fludrocortisone is a synthetic corticosteroid with mineralocorticoid activity that increases sodium resorption and promotes potassium excretion in the distal convoluted renal tubule. It therefore seems a logical option to reverse hyperkalaemia in type 4 renal tubular acidosis; however, we can find no published guideline recommending this use [1,2]...

CONTEXT: Camel milk (CM) is recommended for liver disease patients in Egypt for a strong belief that it has a curative effect. OBJECTIVE: The effect of consumption of CM with or without chemotherapeutic drug cisplatin was evaluated on induced hepatocarcinogenesis in rats. MATERIALS AND METHODS: Wistar male rats (56) were divided into eight groups (7 rats each). Group I was control. Hepatocarcinogenesis was initiated by a single dose of intraperitoneal injection of diethylnitrosamine (DENA) (200 mg/kg BW) and promoted by phenobarbitone (500 ppm) in drinking water in groups V, VI, VII and VIII...

There have been several global epidemics of chronic kidney disease of unknown etiology (CKDu). Some, such as Itai-Itai disease in Japan and Balkan endemic nephropathy, have been explained, whereas the etiology of others remains unclear. In countries such as Sri Lanka, El Salvador, Nicaragua, and India, CKDu is a major public health problem and causes significant morbidity and mortality. Despite their geographical separation, however, there are striking similarities between these endemic nephropathies. Young male agricultural workers who perform strenuous labor in extreme conditions are the worst affected...

Snake bite is mainly an occupational hazard and causes serious health problems in rural India. Acute kidney injury (AKI) occurs in 5-30% cases. Renal pathologic findings include acute tubular necrosis, cortical necrosis, interstitial nephritis, glomerulonephritis, and vasculitis. Thrombotic microangiopathy (TMA) occurrence after a snake bite is reported rarely. Here, we present two patients who developed TMA after viper bite treated with hemodialysis and plasmapheresis. Renal biopsy showed fibrin thrombi in glomeruli and arterioles with cortical necrosis...

Acyclovir is a commonly used antiviral drug. Acute kidney injury (AKI) due to intratubular crystal precipitation and interstitial nephritis is well known. Here we present a case of acyclovir induced AKI in a 61 year old male with herpes zoster, which presented like thrombotic microangiopathy with acute interstitial nephritis. This is the first case report on acyclovir causing thrombotic microaniopathy with partial improvement in renal function after plasmapharesis.

Renal biopsy is crucial while evaluating for the diagnosis of glomerular, vascular, tubulointerstitial, and genetic diseases. It gives vital information which helps in estimating the disease prognosis, progression, and management. This is the retrospective analysis of all adult patients aged above 18 years, who underwent percutaneous renal biopsy at The Kidney Center Post Graduate Training Institute, Karachi, over a duration of 18 years, i.e., January 1, 1996, to December 2013. Renal graft biopsies and those which were inadequate were excluded from analysis...

Over the past four years, all patients with unexplained rapid progression of their renal disease were subjected to kidney biopsy, despite their small size (<9 cm), to define its etiology. Children, pregnant women, morbidly obese patients, and those with an unstable cardiovascular state, septicemia, bleeding diathesis as well as those kidney size with size <6 cm were excluded from the study. Doppler ultrasound was used to exclude renovascular/ischemic nephropathy. The procedure was performed by an interventional radiologist using a biopsy gun technique and under ultrasound guidance...

In recent past, direct-acting anti-viral drugs (DAAs) have become the standard of care for the treatment of hepatitis C virus (HCV) infection. However, the experience with the use of these drugs in Indian renal transplant recipients is limited. We retrospectively reviewed our experience with DAA-based treatment for HCV infection in such patients. Between April 2015 and December 2016, six adults (median age 41 [range 34-52] years, male 5; GT1 2, GT3 3, and GT4 1; including three with prior failed interferon-based treatment) had received genotype-guided, DAA-based anti-HCV treatment 1 to 158 (median 15) months after renal transplantation...

Background: Existing epidemiological studies illustrate that proton pump inhibitors (PPIs) may be related to adverse kidney outcomes. To date, no comprehensive meta-analysis has been conducted to evaluate and quantify this association. Methods: We performed a systematic review and meta-analysis of studies to assess the association between PPI use and the risk of adverse kidney outcomes. We searched MEDLINE, Embase, SCOPUS, Web of Science, CINAHL, Cochrane Library and grey literature with no language restrictions (through 31 October 2016)...

Acute kidney injury (AKI) is a very common complication after allogeneic bone marrow transplantation (BMT) and associated with poor prognosis. Generally kidneys are assumed to be no direct target of Graft-versus-Host Disease (GvHD), and renal impairment is often attributed to several other factors occurring in the early phase after BMT. Our study aimed to prove the existence of renal GvHD in a fully MHC-mismatched model of BALB/c mice conditioned and transplanted according to two different intensity protocols...

A novel autosomal recessive cerebro-renal syndrome was identified in consanguineous Bedouin kindred: neurological deterioration was evident as of early age, progressing into severe intellectual disability, profound ataxia, camptocormia and oculomotor apraxia. Brain MRI was normal. Four of the six affected individuals also had early-onset nephropathy with features of tubulo-interstitial nephritis, hypertension and tendency for hyperkalemia, though none had rapid deterioration of renal function. Genome wide linkage analysis identified an ∼18 Mb disease-associated locus on chromosome 4 (maximal logarithm of odds score 4...

Chronic-Kidney-Disease of Unknown-etiology (CKDu) has been reported in developing-countries like Sri-Lanka, India and Central-America without sparing the Indian sub-district (namely Canacona) located in south-Goa. The disease etiology is unlinked to common causes of diabetes and hypertension and assumed to be environmentally induced due to its asymptomatic-nature and occurrence in groundwater relying communities. This study aimed to understand environmental risk-factors underlying CKDu-etiology using Indian sub-district (Canacona) as case-study...
