Chronic inflammation can be a major driver of the failure of a variety of organs, including chronic kidney disease (CKD). The NLR family pyrin domain-containing 3 (NLRP3) inflammasome has been shown to play a pivotal role in inflammation in a mouse kidney disease model. Nuclear factor erythroid 2-related factor 2 (Nrf2), the master transcription factor for anti-oxidant responses, has also been implicated in inflammasome activation under physiological conditions. However, the mechanism underlying inflammasome activation in CKD remains elusive...

Hepatitis C virus (HCV) is a major cause of liver-associated morbidity and has an increasing prevalence worldwide. Hepatitis C virus infection may lead to chronic hepatitis, cirrhosis and liver failure. However, it is also associated with a wide range of extra-hepatic complications, such as cryoglobulinemia, an immune complex disease associated with cryoglobulin leading to multiple organ damage and, while the major symptom is vasculitis. The present study reported on a-58-year-old woman who was diagnosed with HCV-associated cryoglobulinemia with skin, kidney and blood system damage and biopsy-proven cryoglobulinemia membrano-proliferative glomerulonephritis...

Deep endometriosis is usually defined as endometriosis infiltrating the peritoneum by >5 mm. It sometimes involves the ureter causing hydronephrosis in 5% of cases. The latter is associated with 18% ureteral lesions. Ureteral endometriosis is one of the rare causes of silent Kidney failure. The ureter obstruction can lead to urinary tract obstruction, hydronephrosis and hydroureters. The ureters are usually compressed externally by the endometriotic lesions surrounding it causing extrinsic ureteral endometriosis, and sometimes by pressure from the bulky adenomyotic uterus with paraureteral fibrosis...

A 58-year-old man with idiopathic pulmonary fibrosis, who had received a right-sided single-lung transplant 2 years earlier, was referred to the sleep clinic for the assessment of nocturnal position-dependent episodes of dyspnea and frequent arousals when lying on his right side. There was no subjective worsening of daytime respiratory symptoms, but he complained of fatigue and unrefreshing sleep. His Epworth Sleepiness Scale score was 12/24. After lung transplantation he had a favorable course while receiving immunosuppression with prednisolone, everolimus, and mycophenolate mofetil...

Renal interstitial fibrosis (RIF) is the main process that leads to renal failure. It is necessary to investigate the mechanism of RIF and identify appropriate methods of regulating it. Furthermore, unilateral ureteral obstruction is a frequently used model for the study of RIF. The morphological damage associated with kidney and lung dysfunction was detected using histopathological experiments. Subsequently, high expression of reactive oxygen species (ROS) modulator 1 (ROMO1) and ROS was measured in blood serum...

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...

In its early stages, symptoms of chronic kidney disease (CKD) are usually not apparent. Significant reduction of the kidney function is the first obvious sign of disease. If diagnosed early (stages 1 to 3), the progression of CKD can be altered and complications reduced. In stages 4 and 5 extensive kidney damage is observed, which usually results in end-stage renal failure. Currently, the diagnosis of CKD is made usually on the levels of blood urea and serum creatinine (sCr), however, sCr has been shown to be lacking high predictive value...

Medical therapy for hereditary hepatorenal tyrosinemia (hereditary tyrosinemia type 1, HT-1) with nitisinone was discovered incidentally, and is a by-product of agrochemistry. It blocks the catabolic pathway of tyrosine, thereby leading to a reduction in the accumulation of toxic metabolites in HT-1. It has to be combined with a low-protein diet supplemented with amino acid mixtures devoid of tyrosine and phenylalanine. This treatment option has completely changed the clinical course of patients suffering from HT-1 who used to die in the first few months to years of life from liver failure, renal dysfunction, and/or hepatocellular carcinoma (HCC)...

Pathogenic Leptospira transmits from animals to humans, causing the zoonotic life-threatening infection called leptospirosis. This infection is reported worldwide with higher risk in tropical regions. Symptoms of leptospirosis range from mild illness to severe illness such as liver damage, kidney failure, respiratory distress, meningitis, and fatal hemorrhagic disease. Invasive species of Leptospira rapidly disseminate to multiple tissues where this bacterium damages host endothelial cells, increasing vascular permeability...

Infective endocarditis (IE) may be accompanied by the production of a broad spectrum of autoantibodies, including antineutrophil cytoplasmic antibodies (ANCA). ANCA detection creates difficulties in the differential diagnosis of IE, especially in relation to kidney injury, the determination of the mechanism of which is important for choosing a treatment policy and estimating a prognosis. The paper describes a clinical case of a 57-year-old man who was found to have higher proteinase-3 (PR-3) ANCA titers along with the symptoms of anemia, purpura, and kidney injury during his hospitalization; echocardiography revealed vegetation on the aortic valve...

The amyloidoses are a group of systemic diseases characterized by organ deposition of misfolded protein fragments of diverse origins. The natural history of the disease, involvement of other organs, and treatment options vary significantly based on the protein of origin. In AL amyloidosis, amyloid protein is derived from immunoglobulin light chains, and most often involves the kidneys and the heart. ATTR amyloidosis is categorized as mutant or wild-type depending on the genetic sequence of the transthyretin (TTR) protein produced by the liver...

BACKGROUND: Joubert syndrome (JS) is a clinically and genetically heterogeneous group of rare neurodevelopmental disorder characterised by peculiar midbrain-hindbrain malformation, known as the "molar tooth" sign. JS can manifest a broad range of signs and symptoms. The most common features of JS are hypotonia, ataxia, developmental delay/intellectual disability, abnormal eye movements, and neonatal breathing abnormalities. To date, 29 genes have been shown to cause JS. METHODS: We employed whole-genome single nucleotide polymorphism genotyping in a group of Iranian families with JS and Sanger sequencing of a known mutation associated with JS located in a single homozygous regions shared by affected members of the families...

Gabapentin is almost exclusively cleared by the kidney and thus presents challenges in patients with kidney failure. Gabapentin is known to be effectively cleared by hemodialysis, but the efficiency of clearance by peritoneal dialysis (PD) has not been previously described. We report a case of gabapentin toxicity in a patient on long-term PD who was treated with continuous automated cycling PD. We find that continuous PD provides significant clearance of gabapentin. With 2-L exchanges every 2 hours, we document an apparent elimination half-life of 41...

Vancomycin hydrochloride (VCM) is a glycopeptide antibiotic that is commonly used against methicillin-resistant, Gram-positive cocci despite the nephrotoxic side effects. VCM-induced nephrotoxicity has been reported in 5-28% of recipient patients. Therefore, renal failure induced by VCM has become an important clinical problem. However, the exceedingly complex mechanism of VCM-induced nephrotoxicity is not fully understood. Therefore, this study was designed to clarify time-dependent alterations of VCM-induced nephrotoxicity in mice as a step toward decreasing the risks of kidney injury associated with VCM therapy...
