Several reports have documented various forms of glomerular diseases in adults with myelodysplastic syndromes (MDS), but similar reports in children are lacking. We describe two children with MDS-associated with steroid-responsive nephrotic syndrome (NS). Patient 1, who had MDS with myelofibrosis, presented also hepatosplenomegaly, pancytopenia, chronic hepatitis, moderate proteinuria, hypocomplementamia and elevated ANA titer. During initial prednisone treatment proteinuria markedly diminished and partial but transient haematological improvement occurred. Relapse subsequently occurred that was manifested by overt NS and pancytopenia. High doses of prednisolone led to remission of the renal disease but haematological remission did not occur. Persisting pancytopenia and repeated infections terminated in sepsis, two years after the onset of MDS. Patient 2, who had refractory anaemia with clonal monosomy 19, manifested bowel disease, hepatosplenomegaly, anaemia and non-organic specific autoantibodies. Prednisone led to both clinical and haematological remission. Haematologic disease relapsed 12 months later, when nephrotic-range proteinuria, haematuria and mild azotaemia were also found. Corticosteroid treatment led to long-lasting renal and haematologic remission, maintained by a small dosage of prednisone. In both patients, renal biopsy findings were consistent with those seen in idiopathic NS. A Medline search disclosed 16 cases of glomerulopathy in the course of MDS in adult patients. Clinical features included NS, usually accompanied by renal insufficiency with either acute, chronic, or rapidly progressive glomerulonephritis. On biopsy, membranous nephropathy, crescentic or mesangial proliferative glomerulonephritis and AL amyloidosis, were found. We conclude: (1) that glomerular disease may be present and should be searched for in patients with MDS; (2) that MDS can be added to the list of rare conditions associated with corticosteroid-responsive NS in children.

We report the case of a 18-year-old woman with portal vein thrombosis and chronic hepatitis C virus. Portal vein thrombosis was diagnosed by chance on ultrasound examination during initial hepatitis C virus-positive patient screening. The patient interview revealed a history including exchange transfusion at birth, followed by necrotising ulcerocolitis and septicemia. The investigation of general factors favoring thrombosis showed acquired protein S deficiency and heterozygous factor V Leiden mutation. This case demonstrates the value of systematic investigations for general thrombophilic factors in cases of portal vein thrombosis even when a local cause is found.

Despite the remarkable progress in intensive care medicine, sepsis and shock continue to be major clinical problems in intensive care units. Septic shock may be associated with a toxic state initiated by the stimulation of monocytes by bacterial toxins such as endotoxin, which is released into the bloodstream. This study describes the role of oxidative stress in endotoxin-induced metabolic disorders. We demonstrate that endotoxin injection results in lipid peroxide formation and membrane injury in experimental animals, causing decreased levels of free radical scavengers or quenchers. Interestingly, it was also suggested that tumor necrosis factor (TNF)-induced oxidative stress occurs as a result of bacterial or endotoxin translocation under conditions of reduced reticuloendothelial system function in various disease states. In addition, we suggest that intracellular Ca2+, Zn2+, or selenium levels may participate, at least in part, in the oxidative stress during endotoxemia. On the other hand, it is also suggested that the extent of endotoxin-induced nitric oxide (NO) formation may be due, at least in part, to a change in heme metabolic regulation during endotoxemia. However, in our experimental model, NO is not crucial for lipid peroxide formation during endotoxemia. Sho-saiko-to is one of the most frequently prescribed Kampo medicines and has primarily been used to treat chronic hepatitis. We report that Sho-saiko-to decreases the rh TNF-induced lethality in galactosamine-hypersensitized mice and protects mice against oxygen toxicity and Ca2+ overload in the cytoplasm or mitochondria during endotoxemia. We further suggest that Sho-saiko-to shows a suppressive effect on NO generation in macrophages stimulated with endotoxin and that it may be useful in improving endotoxin shock symptoms.

We report the case of an ABO-incompatible kidney transplant recipient who died suddenly following a good transplant course of 12 years. For 10 years after transplantation, the graft function had been stable (s-Cr: 1.0-1.5 mg/dL), although chronic hepatitis C had developed, with elevation of transaminase. In the 11th year, he was admitted into the hospital with low-grade fever and general fatigue. Jaundice and anaemia progressed, and he died 2 months after admission. The autopsy diagnosis was: (1) post-renal transplantation state, (2) phlegmonous enterocolitis with septic infarction, (3) cellulitis and necrotic myositis, and (4) sepsis. The transplanted kidney graft showed well-preserved glomeruli and tubules, corresponding to chronic allograft nephropathy (CAN) grade Iota (ci1, ct1, cv1), according to the Banff classification. The pathological changes observed in this long-surviving ABO-incompatible kidney graft were similar to those of an ABO-compatible graft, although its degree was milder.

We report a case of acute fatal exacerbation of chronic hepatitis B in a 50-year-old man with multiple myeloma being treated with thalidomide. The patient had a medical history of chronic hepatitis B and was diagnosed with stage IIIA multiple myeloma. He suffered two episodes of transient transaminitis of unknown origin after successive autologous stem cell transplantations. Spontaneous resolutions of the transaminitis were observed without special management. At that time, PCR of hepatitis B virus (HBV) were all-negative. After 5-months' administration of thalidomide for the second relapse of the multiple myeloma, he suddenly experienced dizziness and jaundice. The level of HBV DNA was 1,641 pg/mL and the serologic tests for other viruses were negative. Despite conventional supportive care, he expired due to septic shock caused by Klebsiella pneumonia. Based on the stable disease status of the multiple myeloma and exclusion of other hepatotoxic agents, it was assumed that the exacerbation of the hepatitis B virus during the thalidomide therapy preceded the bacterial sepsis. With the increased use of thalidomide in cancer treatment, cautious monitoring of the viral burden should be performed in patients with chronic hepatitis B.

Within a few minutes of an intravenous injection of a lipopolysaccharide (LPS) into mice, platelets accumulate, largely in the lung. At higher doses, LPS induces rapid shock (within 10 min), leading to death within 1 h. This type of shock differs from so-called endotoxin shock, in which shock signs and death occur several hours or more later. Here, we found that platelet depletion (by a monoclonal anti-platelet antibody) prevented LPS-induced rapid shock, but increased delayed lethality. In Japan, glycyrrhizin (GL), a compound isolated from licorice, is daily and slowly infused intravenously into chronic hepatitis C patients. A single bolus intravenous injection into mice of GL (200 mg/kg or less) shortly before (or simultaneously with) LPS injection reduced the pulmonary platelet accumulation and the severity of the rapid shock, and prevented death in both the early and later periods. GL itself, at 400 mg/kg, produced no detectable abnormalities in the appearance or activity of mice. Intraperitoneal injection of aspirin or dexamethasone had only marginal effects on LPS-induced platelet responses and lethality. These results suggest that platelets play important roles in the development of both the rapid and delayed types of shock induced by LPS. Although the mechanism by which GL suppresses platelet responses and delayed lethality remains to be clarified, GL might provide a strategy for alleviating the acute respiratory distress syndrome seen in sepsis. Our results may also support the proposal by Cinatl et al. [Cinatl J, Morgenstern B, Bauer G, Chandra P, Ravenau H, Doerr HW. Glycyrrhizin, an active component of liquorice roots, and replication of SARS-associated coronavirus. Lancet 2003; 361: 2045-6.] that GL may be an effective drug against severe acute respiratory syndrome.

Chronic C hepatitis is a global health problem. Its treatment is still unresolved. Pegylated interferon means substantive breakthrough in therapy. The longer effect, the lasting, steady therapeutic blood level are the pharmacokinetic advances. There is no significant difference in the side effects of pegylated interferon and standard interferon. The most frequent side effects leading to dose reduction or cessation of the treatment are depression and hematologic disorders. Neutropenia is induced more frequently by pegylated interferon, than by the standard form according to the literature. Combined antiviral treatment (pegylated interferon alpha-2a and ribavirin) of a 54 years old woman, who suffered from posttransfusion chronic hepatitis C was started. The dose of the pegylated interferon alpha-2a and ribavirin was reduced at the 8th week due to leucopenia and mild anemia. Fever, cough, sore throat and weakness occurred. Agranulocytosis was detected which was accounted as a side effect of pegylated interferon treatment. Antibiotic, antimycotic therapy and filgastrim was given. Leukocyte number increased, fever stopped after 10 days of therapy. The patient returned 17 days later. She had been having high fever, weakness, sore throat for 4 days. Ciprofloxacin was given by GP before her registration because of the suspicion of urinary infection, then she took sulfamethoxazol + trimethoprim without medical advise. Agranulocytosis was detected again, Staphylococcus sepsis developed. No sign of hematologic disease was found in the bone marrow. Agranulocytosis was considered aftermath of sulfamethoxazol + trimethoprim. Antibiotics, antimycotic and antiviral treatment, and filgastrim were given, sepsis healed, leukocyte number became normal. 274 patients suffering from chronic hepatitis C were treated by standard interferon, and 43 were treated by pegylated interferon. Rapid and significant decrease of leukocyte count was observed in the patients treated by pegylated interferon in the first 4 weeks of the treatment then it remained stable. Cessation of the treatment or dose-reduction was not necessary due to neutropenia among patients treated by standard interferon, while dose reduction was reasonable in two more cases in addition to this one, treated by pegylated interferon. The authors stress the importance of the exact follow-up of patients according to the protocol, which renders the early recognition of side effects, the prevention of complications, and their early and adequate treatment possible. Thus, pegylated interferon--inspite of its marked side effects and more serious suppressive effect on bone marrow--is the most effective drug for the treatment of chronic hepatitis C.

In the study we described severe adverse events such as sepsis and bacterial endocarditis in the patient treated because of chronic hepatitis C (CHC). A case of 57 year old man with CHC, with recurring increased aminotransferases up to 100 IU/l; histological result of liver biopsy--G3, S2, HCV-RNA positive, genotype--HCV1b. The therapy with peginterferon alfa and ribavirin was introduced. The negative result of HCV RNA was obtained in 12th week of treatment. In the 7th month the patient was admitted to the hospital because of sepsis due to Escherichia coli, acute renal insufficiency and right orchitis. In spite of the treatment and general clinical improvement, the patient was still febrile. The bacterial endocarditis was found after number of diagnostic procedures. The treatment of endocarditis lasted 6 weeks in the hospital. During the hospitalization and 6 months after the HCV-RNA were performed with the negative results. The therapy of CHC with peginterteron and ribavirin is save in most cases however requires increased clinical surveillance, especially in the second half-year.

Pulmonary manifestations of interferon (IFN) use are a rare but well known complication seen with both standard and pegylated interferon alpha-2b (pegIFNalpha-2b) forms of the agent. These are generally of modest intensity and reversible. We report the first case of fulminant adult respiratory distress syndrome (ARDS) associated with pegylated interferon alpha-2a (pegIFNalpha-2a) and ribavirin use for hepatitis C, complicated by subsequent and ultimately fatal sepsis and multiorgan failure. Practicing gastroenterologists and intensivists alike need to be aware of the potential for serious pulmonary sequelae with the use of combination therapy for chronic hepatitis C viral (CHCV) infections.
