There are 2 major categories of patients with seizures and chronic kidney disease (CKD): patients who develop acute symptomatic seizures in the setting of CKD and patients with epilepsy who at some point develop CKD. The incidence of uremic seizures with kidney failure is ∼10%. These seizures are often nonconvulsive and may mimic uremic encephalopathy. Recognition and management of such situations may be challenging for treating physicians who are non-neurologists. Furthermore, practitioners caring for patients with seizures with or without an established diagnosis of epilepsy in the setting of CKD frequently encounter challenges in the selection, loading, titration, and maintenance of antiepileptic drugs (AEDs) due to potentially altered pharmacokinetics of the AEDs...

Uremic encephalopathy is a severe complication of renal failure. The underlying pathogenesis is unknown although several mechanisms have been suggested. Renal failure causes oxidative stress leading to cardiovascular complications. It has been suggested as the potential mediator of uremic encephalopathy as well, but it is largely unknown whether brain tissue itself undergoes oxidative damage in uremia. The aim of our experiment was to analyze oxidative stress markers in different brain regions in an animal model of acute kidney injury (AKI)...

Purple urine-bag syndrome is a rare condition that occurs in patients with indwelling urinary catheters carried over a long period and frequently associated with a urinary tract infection. It is characterized by the appearance of a violet coloration of the probe and/or the urine collection bag. We report the first case in West Africa that occurred in a 47-year-old woman in uremic encephalopathy and carrier of a urinary catheter, which presented a violet color of the tubing and urine-bag associated with a urinary tract infection...

Posterior reversible encephalopathy syndrome (PRES) is a clinical syndrome characterized by headaches, seizures, a confusional state and visual disturbances associated with transient predominantly bilateral posterior white mater magnetic resonance imaging lesions. It is primarily reported in the setting of hypertension, acute renal failure, peripartum eclampsia, autoimmune disease, immunosuppression and chemotherapy. Thrombotic microangiopathy (TMA), including hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) has also been reported as potential PRES inducer...

Cytokines play an important role in the pathogenesis of the severe complications of Shiga toxin-producing Escherichia coli (STEC) infection, such as hemolytic uremic syndrome (HUS) and acute encephalopathy. A 3-year-old boy with acute encephalopathy associated with STEC O-157 HUS showed increased levels of IL-6 and IL-10, which normalized after methylprednisolone pulse therapy, and additionally exhibited a transient increase of glutamine on MR spectroscopy. This finding suggests that excitotoxicity, in addition to hypercytokinemia, may play an important role in the pathogenesis of HUS encephalopathy...

Vitamin deficiency disorders display a wide variety of neurologic signs and symptoms, the pathogenesis of which is not clearly understood. Metabolic encephalopathies (hepatic, hypoglycemic, and uremic) have to be considered in the differential diagnosis of patients with cognitive impairment, motor disturbances, psychiatric symptoms, seizures, and neuropathies. Calcifications (vascular wall and parenchymal) occur in the normal aging brain and in neurodegeneration; some associated genes are already described.

The encephalopathy that occurs in association with hemolytic uremic syndrome (HUS), which is caused by enterohemorrhagic Escherichia coli (E. coli), has a high mortality rate and patients sometimes present sequelae. We herein describe the case of a 20-year-old woman who developed encephalopathy during the convalescent stage of HUS caused by E.coli O26. Hyperintense lesions were detected in the pons, basal ganglia, and cortex on diffusion-weighted brain MRI. From the onset of HUS encephalopathy, we treated the patient with methylprednisolone (mPSL) pulse therapy alone...

Perhaps no other organ in the body is affected as often and in as many ways as the brain is in patients with chronic kidney disease (CKD). Several factors contribute to the neurological disorders in CKD including accumulation of uremic toxins, metabolic and hemodynamic disorders, oxidative stress, inflammation, and impaired blood brain barrier among others. The neurological disorders in CKD involve both peripheral and central nervous system. The peripheral neurological symptoms of CKD are due to somatic and cranial peripheral neuropathies as well as a myopathy...

BACKGROUND: Uremic Encephalopathy (UE) is a neurological complication associated with acute or chronic renal failure. Imaging findings of UE may present involvement of the basal ganglia, cortical or subcortical regions, and white matter. We report a rare case of UE caused by neurogenic bladder with isolated brainstem involvement revealed by magnetic resonance imaging (MRI). Immediate therapy resulted in full recovery of neurological signs and changes on MRI. CASE PRESENTATION: A 14-year-old Han Chinese woman with a history of chronic renal failure caused by neurogenic bladder...

Neurological manifestations related to electrolyte disorders, drug toxicity, and uremia are common in chronic kidney disease (CKD). Seizures and coma are frequent complications of acute renal insufficiency (uremia), whereas peripheral neuropathy and encephalopathy, observed in progressive uremia, are terminal events. Failure to excrete metabolic products causes their accumulation and can lead to severe intoxication. Clinically, the signs and symptoms of uremia can vary widely, depending on the biological characteristics of the patient, the specific type of renal disease, and the time of the uremic intoxication...

PURPOSE OF REVIEW: Neurologic dysfunction is prevalent in patients with acute and chronic renal disease and may affect the central nervous system, peripheral nervous system, or both. Neurologic manifestations may result directly from the uremic state or as a consequence of renal replacement therapy. Early recognition of neurologic dysfunction may provide opportunities for intervention and reduced morbidity. RECENT FINDINGS: Advances in the understanding of neurologic complications of renal disease and its treatments have led to more widespread recognition and earlier identification of encephalopathy syndromes such as cefepime neurotoxicity and posterior reversible encephalopathy syndrome (PRES), dramatic reductions in the incidence of dialysis disequilibrium syndrome and dialysis dementia, and improved survival in disorders such as von Hippel-Lindau disease and thrombotic thrombocytopenic purpura...

Dialysis disequilibrium syndrome is a neurological adverse effect of acute hemodialysis in advanced uremic patients. Dialysis disequilibrium has a wide spectrum of clinical manifestations starting from subtle uneasiness, confusion, to florid and complex life threatening neurological deficit. In this case study, we present a patient who developed sudden cortical blindness following hemodialysis due to posterior reversible encephalopathy, which is a rare presentation of dialysis disequilibrium syndrome.

Enterohemorrhagic Escherichia coli (EHEC) O26 infections cause severe human diseases such as hemolytic uremic syndrome and encephalopathy, and is the predominant serogroup among non-O157 EHEC in many countries. Shiga toxin (Stx), which consists of two distinct types (Stx1 and Stx2), plays a central role in EHEC pathogenesis. The major stx gene type in EHEC O26 strains is stx1, although isolates with only stx2 have emerged in Japan since 2012 and have been reported in Europe. In this study, we selected 27 EHEC O26 strains isolated in Japan and identified a distinct genetic clade within sequence type (ST) 29, designated ST29C1, that carried only stx2 and had the plasmid gene profile ehxA+/katP-/espP+/etpD-...

Mental disturbances have been described in patients with Parkinson's Disease (PD). Of these, the common conditions are delirium and psychosis. Delirium has been attributed to change of environment, especially hospital stay and infections; while psychosis is due to drugs like dopamine agonists. This is a case of a 75-year-old male, on levodopa therapy for PD, who presented with delirium and ended up with a cocktail diagnosis: Cryptococcal meningitis, Hashimoto's Encephalopathy (HE), Urinary tract infection with acute renal failure, Uremic encephalopathy and Levodopa induced psychosis...
