Iodinated radiocontrast media (IRCM) is widely used in current clinical practice. Although IRCM is generally safe, serious adverse drug reactions (ADRs) may still occur. IRCM-induced ADRs may be subdivided into chemotoxic and hypersensitivity reactions. Several factors have been shown to be associated with an increased risk of ADRs, including previous contrast media reactions, history of asthma and allergic disease, etc. Contrast media with lower osmolality is generally recommended for at-risk patients to prevent ADRs. Current premedication prophylaxis in at-risk patients may reduce the risk of ADRs. However, there is still a lack of consensus on the prophylactic role of premedication. Contrast-induced nephropathy (CIN) is another component of IRCM-related ADRs. Hydration remains the mainstay of CIN prophylaxis in at-risk patients. Despite several preventive measures, ADRs may still occur. Treatment strategies for potential contrast reactions are also summarised in this article. This article summarises the pathophysiology, epidemiology and risk factors of ADRs with emphasis on prevention and treatment strategies. This will allow readers to understand the rationale behind appropriate patient preparation for diagnostic imaging involving IRCM.

5.Acute liver failure in Korea: etiology, prognosis and treatment.
The Korean Journal of Hepatology 2010;16(1):5-18
Acute liver failure (ALF) is a rare condition in which rapid deterioration of liver function results in altered mentation and coagulopathy in individuals without previously recognized liver disease. The outcomes of patients with ALF vary greatly according to etiology, and the etiology of ALF varies markedly by geographical region. In Korea, about 90% of ALF are associated with etiologies that usually result in poor outcomes, including hepatitis B virus (HBV) infection and herbal remedies. The main causes of death in patients with ALF are increased intracranial pressure, systemic infection, and multi-organ failure. Recent advances in the intensive care of patients with ALF have contributed to a marked improvement in their overall survival. Emergency adult to adult living-donor liver transplantation (LDLT) can be performed expeditiously and safely for patients with ALF, and greatly improves survival rate as well as deceased-donor transplantation. As the window during which transplantation is possible is limited, emergency adult LDLT should be considered to be one of the first-line treatment options in patients with ALF, especially in regions in which ALFs are caused by etiologies associated with poor outcome and the supply of organs is very limited.

Neostigmine can successfully decompress patients with acute colonic pseudo-obstruction (ACPO) who are unresponsive to conservative therapy. However, neostigmine is contraindicated in renal failure, so it is underused in ACPO patients with renal failure who would be otherwise appropriate candidates. We described the first successfully treated case of acute kidney injury (AKI) with neostigmine in a patient with ACPO. A 72-year-old man who underwent a coronary artery bypass graft surgery 11 days prior presented to the emergency room with abdominal distension, peripheral edema, and dyspnea on exertion. Plain abdominal radiographs and abdomen computed tomography scan showed diffuse colonic dilatation without obstruction. Serum creatinine level was increased five-fold over baseline. We diagnosed the patient as ACPO with AKI. With conservative treatment, renal function failed to improve because the ACPO was not corrected. Administration of neostigmine rapidly resolved ACPO and renal function, avoiding more invasive procedures such as colonoscopic decompression and hemodialysis. Neostigmine appears to be an effective and safe treatment option for ACPO patients with renal failure. Prospective large-scale studies should be carried out to determine the safety and efficacy of neostigmine in ACPO patients with renal failure.

OBJECTIVEThe present study is to investigate the protective effects of asiaticoside on sepsis-induced acute kidney injury in mice.
METHODWith the sepsis induced by cecal ligation and puncture (CLP), forty eight kunming mice were randomly divided into four groups as sham operated, CLP treated, CLP + asiaticoside 15, 45 mg x kg(-1) groups. General conditions and the amount of dead rate of mice were observed. The BUN and Cr levels were observed by the kits. IL-6 in serum was assayed by enzyme-linked immunosorbent assay (ELISA). Kidney tissues were harvested for determination of iNOS expression by Western blotting analysis. The pathologic changes were observed under electron microscope via hematoxylin-eosin (HE) stain.
RESULTCompared with CLP group, the death rate, the levels of BUN, Cr, IL-6, and iNOS protein expression of asiaticoside groups were significantly reduced. The pathologic changes in kidney tissues induced by sepsis were significantly attenuated dose-dependently by asiaticoside under electron microscope.
CONCLUSIONAsiaticoside has protective effects against sepsis-induced acute kidney injury, which were probably associated with the inhibition of IL-6 in serum and iNOS protein in kidney tissues.

Glomerulonephritis occurs as a rare form of renal manifestation in Plasmodium falciparum malaria. Herein, we report a case of falciparum malaria-associated IgA nephropathy for the first time. A 49-yr old male who had been to East Africa was diagnosed with Plasmodium falciparum malaria. Microhematuria and proteinuria along with acute kidney injury developed during the course of the disease. Kidney biopsy showed mesangial proliferation and IgA deposits with tubulointerstitial inflammation. Laboratory tests after recovery from malaria showed disappearance of urinary abnormalities and normalization of kidney function. Our findings suggest that malaria infection might be associated with IgA nephropathy.

OBJECTIVETo investigate the change in renal high mobility group box-1 protein (HMGB1) levels, and the effect of Chinese traditional medicine-Xuebijing injection on HMGB1 expression as well as acute kidney injury in rats after scald injury.
METHODSWistar rats were subjected to 30% full-thickness scald injury followed with delayed resuscitation. Totally 78 animals were divided into sham scald group (n=18), scald injury group (n=30), and Xuebijing injection treatment group (n=30). All animals were sacrificed at 8, 24, and 72 hours postburn. Renal tissue and blood samples were harvested to determine HMGB1 mRNA as well as protein expression and organ functional parameters. HMGB1 mRNA level was semi-quantitatively measured by the reverse transcription polymerase chain reaction taking GAPDH as an internal standard, and protein expressions of HMGB1 were detected by both Western blot and immunohistochemistry. Serum creatinine (Cr) contents were measured by automatic biochemistry analyzer. In addition, pathological lesions in kidney were observed under light microscope using HE staining.
RESULTSCompared with sham scald group, both mRNA and protein expressions of HMGB1 were significantly enhanced in the kidney at 8, 24, and 72 hours after scald injury (P<0.05, P<0.01), meanwhile serum Cr contents were markedly increased following acute insults (P<0.05, P<0.01). Treatment with Xuebijing injection could markedly down-regulated renal HMGB1 mRNA expression and protein release at 24 hours and 72 hours (P<0.05, P<0.01), and significantly reduced serum Cr content following scald injury (P<0.05). Many inflammatory cells in renal tissues were observed using light microscope following scald. The histological morphology of kidney lesions was a-HMGB1, a late mediator, appears to be inmeliorated after treatment with Xuebijing injection.
CONCLUSIONSvolved in the pathogenesis of excessive inflammatory response and acute kidney damage. Treatment with Xuebijing injection can inhibit HMGB1 synthesis and release in renal tissues, and may prevent the development of acute kidney injury induced by serious scald injury.

Hepatitis A is typically a self-limited acute illness that does not progress to chronic hepatitis. In rare cases, acute hepatitis A can be associated with serious complications (such as fulminant hepatitis or acute kidney injury) and may result in death or liver transplantation. Pure red cell aplasia (PRCA) is a rare hematologic disorder characterized by anemia, reticulocytopenia in the blood, and isolated erythroblastopenia with normal granulopoiesis and megakaryopoiesis in the bone marrow. PRCA is a rare hematopoietic complication of acute viral hepatitis, and few cases associated with hepatitis A virus infection have been reported. Recently, we experienced a case of severe hepatitis A complicated by fulminant hepatitis and acute kidney injury followed by PRCA which showed a favorable response to oral corticosteroids.
