This review summarizes the data on the diagnostic value of determining the fatty acid-binding protein (FABP) in urological and nephrological diseases. A physiological role of this protein in the pathogenesis of malignant neoplasms of the kidney, bladder, and prostate was analyzed. The dynamics of FABP in serum and urine with decreased renal function was studied: this protein is considered as a diagnostic and prognostic marker for chronic kidney disease and acute renal injury. The value of FABP for early screening of patients with obstructive nephropathy was revealed, and its role in predicting the restoration of kidney function was studied: the dynamics of FABP content can characterize the process of graft recovery, determine the need for hemodialysis. In patients with oligozooastenospermia, a reduced content of FABP in the ejaculate was registered, which was probably an adverse sign indicating a violation of male fertility.

Congenital anomalies of the urinary tract, and particularly of obstructive nephropathy such as ureteropelvic junction obstruction (UPJO) in infants, can later lead to chronic kidney disease and hypertension. Fundamental questions regarding underlying mechanisms remain unanswered. The aim of the present study was to quantitate the systemic amino acids metabolome in 21 UPJO infants requiring surgery (Group A) and 21 UPJO infants under conservative treatment (Group B). Nineteen healthy age-matched infants served as controls (Group C). Serum amino acids involved in several pathways and representative metabolites, including the L-arginine-derived nitric oxide (NO) metabolites nitrite and nitrate and the lipid peroxidation biomarker malondialdehyde (MDA) were measured by gas chromatography–mass spectrometry (GC–MS) methods using their stable-isotope labeled analogs as internal standards after derivatization to their methyl esters N-pentafluoropropionic amides (amino acids) and to their pentafluorobenzyl derivatives (nitrite, nitrate, MDA). The concentrations of the majority of the biomarkers were found to be lower in Group A compared to Group B. Statistical analysis revealed clear differentiation between the examined study groups. Univariate statistical analysis highlighted serum homoarginine (q = 0.006), asymmetric dimethylarginine (q = 0.05) and malondialdehyde (q = 0.022) as potential biomarkers for UPJO infants requiring surgery. Group A also differed from Group B with respect to the diameter of the preoperative anterior–posterior renal pelvis (AP) as well as regarding the number and extent of inverse correlations between AP and the serum concentrations of the biomarkers. In Group A, but not in Group B, the AP diameter strongly correlated with hydroxy-proline (r = −0.746, p = 0.0002) and MDA (r = −0.754, p = 0.002). Our results indicate a diminished amino acids metabolome in the serum of UPJO infants requiring surgery comparing to a conservative group.

Aim: To reveal the alterations of N6-methyladenosine (m6A) epitranscriptome profile in kidney after unilateral ureteral obstruction in mice. Materials & methods: Total renal m6A and expressions of methyltransferases and demethylases were detected by colorimetric quantification method, real-time PCR and western blot, respectively. Methylated RNA immunoprecipitation sequencing was performed to map epitranscriptome-wide m6A profile. Results: Total m6A levels were time-dependent decreased within 1 week, with the lowest level detected at day 7. A total of 823 differentially methylated transcripts in 507 genes were identified. Specifically, demethylated mRNAs selectively acted on multiple pathways, including TGF-β and WNT. Conclusion: m6A modification has a functional importance in renal interstitial fibrosis during obstructive nephropathy and might be a promising therapeutic target.

End Stage

A middle-aged woman with end-stage renal disease (ESRD) due to obstructive nephropathy presented to the hospital for an episode of unresponsiveness and hypoglycaemia. Initially, she was diagnosed with hypoglycaemia associated with ESRD and was discharged. However, she returned to the hospital after experiencing tonic–clonic seizures and recurrent hypoglycaemia. Her hypoglycaemia workup revealed an elevated insulin-like growth factor 2 (IGF2) to IGF1 ratio consistent with paraneoplastic IGF2 secretion. Subsequently, a CT abdomen revealed a retroperitoneal mass, found to be a retroperitoneal sarcoma. Her hypoglycaemia was treated with glucocorticoids and growth hormone. Surgical debulking of her tumour was attempted, but she expired due to postoperative haemorrhagic shock. Doege-Potter syndrome is a rare cause of hypoglycaemia which should be suspected in any new-onset, worsening, inexplicable or refractory hypoglycaemia, particularly in non-diabetic ESRD. Here we present a report of retroperitoneal sarcoma presenting with hypoglycaemia in a patient with ESRD without diabetes.

Tubular Dilatation

We have observed a renal toxicity consistent with an obstructive protein cast nephropathy in cynomolgus macaques but not in other species treated with different therapeutic candidates having a common carboxylic acid moiety, suggesting a species-specific sensitivity. Here, we present renal toxicity findings consistent with a protein cast nephropathy in a 2–week safety study in cynomolgus monkeys. Light microscopic changes consisted of intratubular cast formation, tubular dilatation, interstitial inflammation, and expansion of the medullary interstitium. Tubular cast material was identified as Tamm-Horsfall protein (THP) and, on ultrastructure, crystalloid material was present in vacuoles of tubular epithelium. It is hypothesized that microcrystal formation in the urinary tubular spaces induces aggregation of THP protein and cast formation in monkeys. Drug-induced obstructive nephropathy is not identified as a major problem in humans; thus, the clinical relevance of the above findings in monkeys is not clear.
