Interleukin-6 (IL-6) plays a key role in inflammatory and immune responses in the host. In the present study, the IL-6 activity in urine from patients with various renal diseases was examined to elucidate the pathological and clinical significance of urinary IL-6. In patients with mesangial proliferative glomerulonephritis (mes-PGN) including, IgA nephropathy, the urinary IL-6 activity tended to increase with the progression of mesangial hypercellularity. In four patients with IgA nephropathy, urinary IL-6 activity increased markedly but transiently during episodes of acute exacerbation associated with upper respiratory tract infection. In addition, it was demonstrated that urine from patients with other types of PGN such as poststreptococcal acute glomerulonephritis and membrano-proliferative glomerulonephritis contained large quantities of IL-6. However, the levels of urinary IL-6 activity were almost within the normal range in non-proliferative glomerular diseases such as membranous nephropathy, minimal change nephrotic syndrome and lupus nephritis (WHO class I and V), non-glomerular bleeding and orthostatic proteinuria. It should be noted that a marked increase in urinary IL-6 was often observed in the patients with urinary tract infection. These results indicated that IL-6 in urine might be derived from various types of cells participating in inflammatory reactions not only in the renal parenchyma but also in the urinary tract.

The severity of the poststreptococcal acute glomerulonephritis is considered to be modulated by the immune response of each individual, although there had been few reports regarding specific factors. Renal cell carcinoma is a cancer frequently associated with paraneoplastic syndrome, characterized by fever, leukocytosis, elevated cytokines, and elevated hormone levels. All of these symptoms resolve after tumor resection. A girl with renal cell carcinoma developed renal failure rapidly, which resolved promptly right after nephrectomy for the carcinoma. She was diagnosed as having poststreptococcal acute glomerulonephritis according to the results of pathological and serological examinations. In addition, elevated serum interleukin-6 level before the surgery was detected. Six and a half years after the diagnosis, the patient's renal function was within normal range and she was tumor free. Because of the quick resolution of her renal dysfunction after the nephrectomy, paraneoplastic syndrome induced by renal cell carcinoma seemed to play a key role in the accentuation of poststreptococcal acute glomerulonephritis.

Coronavirus disease 2019 (COVID-19) is a viral disease induced by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), which may cause an acute respiratory distress syndrome (ARDS). First reports have shown that elevated levels of inflammatory cytokines might be involved in the development of organ dysfunction in COVID-19. Here, we can present a case of cytokine release syndrome induced by SARS-CoV-2 causing multiorgan failure and death. Of note, we can report on pulmonary vein thromboses as potential source of cerebrovascular embolic events. Furthermore, we present a specific form of an isolated inflammatory atrial cardiomyopathy encompassing atrial myocardium, perivascular matrix, as well as atrial autonomic nerve ganglia, causing atrial fibrillation, sinus node arrest, as well as atrial clot formation in the right atrial appendage. An associated acute glomerulonephritis caused acute kidney failure. Furthermore, all the described pathologies of organs and vessels were associated with increased local expression of interleukin-6 and monocyte chemoattractant protein-1 (MCP-1). This report provides new evidence about fatal pathologies and summarizes the current knowledge about organ manifestations observed in COVID-19.
