Case is described with acute renal failure in Henoch's nephritis with intra- and extracapillary cellular proliferation. The disease was manifested with its classical picture: characteristic purpura, articular pains in the wrist and ankle joints, mucous-bloody diarrhea. The renal changes originated at the very beginning of the hemorrhagic vasculitis and clinically was manifested with acute renal failure and severe nephrotic syndrome. Under the effect of hemodialysis and complex drug treatment with cytostatics, glucocorticoids, anticoagulants, plasma- and bloodtransfusions, a very good clinical and paraclinical effect was attained. No recurrences of the main disease were recorded during the six-year clinical observation. A stability of the renal function was observed in the patient, with the exception of the persiting proteinuria with values under 10 g/l.

In order to reproduce pharmacokinetics (PK) profiles seen in vivo, the Hollow Fiber Infection Model (HFIM) is a useful in vitro module in the evaluation of antimicrobial resistance. In order to reduce the consumption of culture medium and drugs, we developed a hollow fiber microreactor applicable to the HFIM by integrating the HFIM function. Next, we constructed a novel control method by using the "digital twin" of the microreactor to achieve precise concentration control.

A 39-year-old male kidney transplant recipient with Down syndrome (DS) was admitted to our hospital for biopsy. He had proteinuria at age 9, was diagnosed with immunoglobulin A nephropathy (IgAN) at age 22, had a tonsillectomy at age 35, and underwent ABO-compatible kidney transplantation (from his mother) at age 36. His serum creatinine was stable at 2.

IgA nephropathy (IgAN) cases histopathologically showing glomerular capillary IgA deposition represent a rare subtype of primary IgAN. Patients with IgAN categorized to this subtype often exhibit heavy proteinuria, advanced histological findings, and are resistant to therapies. Here, we report three cases of biopsy-proven IgAN with glomerular capillary IgA deposition who presented acute deterioration of urinalysis findings following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccinations.

Podocyte loss is the fundamental basis of glomerulosclerosis. Focal segmental glomerulosclerosis (FSGS) is a progressive glomerular disease, and its glomerular features are a prototype of podocyte loss-driven glomerulosclerosis. The glomerular pathology of FSGS is characterized by a focal and segmental location of the sclerotic lesions in human FSGS; segmental sclerosis often shows simultaneous intra- and extra-capillary changes, including parietal cell migration, capillary collapse, hyaline deposition, and intra-capillary thrombi and occasional hypercellularity.

Diffusion MRI is an efficient and widely used technique for the investigation of tissue structure and organisation in vivo. Multiple phenomenological and biophysical diffusion models are intensively exploited for the analysis of the diffusion experiments. However, the verification of the applied diffusion models remains challenging.
