A 67-year-old man with a one-and-a half-year history of Raynaud's phenomenon was admitted to our hospital for progressive dyspnea occurring over the previous two weeks. Physical examination revealed a blood pressure of 200/124 mmHg, and slightly tight and smooth skin of the fingers, hands and forearms. Laboratory evaluation included serum creatinine of 5.42 mg/dl, plasma renin activity > 20 ng/ml/hr, and antinuclear antibody with a titer of 1 : 1,280. Renal biopsy was performed and the histopathological findings showed that some glomeruli exhibited ischemic retraction with wrinkling of the basement membranes, and that one arteriole exhibited significant intimal hyperplasia with luminal stenosis. These findings were compatible with scleroderma renal crisis (SRC). On the 5th day, serum creatinine had risen to 9.16 mg/dl, and he required temporary hemodialysis therapy. After the administration of captopril was started, his blood pressure fell to 160/86 mmHg and serum creatinine was reduced to 5.12 mg/dl. On the 9th day, he exhibited skin eruptions, and captopril was discontinued accordingly and temocapril started. Because of continued eruptions, temocapril was replaced by losartan. His blood pressure was controlled easily and his serum creatinine level reduced steadily. One year after the start of losartan, serum creatinine was 2.25 mg/dl and blood pressure was 130/82 mmHg. SRC is a life-threatening manifestation of systemic sclerosis. In the late 1970s, angiotensin converting enzyme (ACE) inhibitor was introduced and has dramatically improved the outcome in SRC patients. As ACE inhibitors act mainly on hyperreninemic renal vasoconstrictive hypertension in SRC, we would expect losartan, a selective antagonist of angiotensin receptor subtype 1, to be interchangeable with ACE inhibitors in SRC. In 1997, Caskey and colleagues reported the failure of losartan to control hypertension in a patient of SRC, and the reason has remained unclear. We report here, a case of SRC whose blood pressure was controlled successfully and his renal failure reversed by the administration of losartan.

We describe a 36 year old man who was admitted to the hospital with dyspnea, edema of the lower limbs, arterial hypertension and oliguric renal failure. He had microhematuria and nephrotic range proteinuria, immunological tests were normal or negative. Renal biopsy revealed global (55%) or segmental glomeruloesclerosis, remaining glomeruli showed extracapillary proliferation (25%). Immunofluorescence study disclosed IgA mesangial deposits. He was also diagnosed as having liver cirrhosis with positive serology against hepatitis C virus. He was treated with dialysis, antihypertensive drugs and steroids with improvement of the renal function. However, ten months later maintenance hemodialysis became necessary. We emphasize two points: first IgA glomerulonephritis is rarely associated with hepatitis C infection, and second crescentic IgA nephropathy has been infrequently reported in liver cirrhosis.

A 52-year-old woman with a medical history of diabetes mellitus type 2, chronic alcoholism and liver function disorders was hospitalized because of complaints of haematemesis, abdominal complaints and dyspnoea. This was due to a severe lactic acidosis caused by acute alcohol intoxication and the use of metformin. With bicarbonate infusion and haemofiltration, the lactic acidosis disappeared, but she developed a distributive shock with multiple organ failure and died 23 days after admission. Lactic acidosis is a rare but serious adverse effect of metformin. Almost all patients described had contraindications to the drug, like renal failure, liver disease, alcohol abuse, and intercurrent conditions causing hypoxia or ischaemia. It is important to be aware of the circumstances in which metformin should not be prescribed.

We report the use of thoracoscopic pericardiectomy to treat two elderly patients with massive pericardial effusion caused by uremic pericarditis. A 79-year-old man, admitted to our hospital complaining of dyspnea, was diagnosed with end-stage renal failure and began maintenance hemodialysis. Although intensive hemodialysis was performed, the patient could not remain on hemodialysis because of severe hypotension during the procedure. Echocardiography revealed massive pericardial effusion and severe hypokinesis of the left ventricular wall. Pericardiocentesis was performed first, without success, followed by thoracoscopic pericardiectomy under general anesthesia. One month after the pericardiectomy, episodes of hypotension during hemodialysis improved, and dyspnea diminished. Echocardiography showed no pericardial effusion and improvement of left ventricular wall motion. Pericarditis is a fatal complication in patients with end-stage renal failure and patients on maintenance hemodialysis. The second patient received the same procedure with a similar improvement of clinical symptoms. These cases suggest that thoracoscopic pericardiectomy is a safe and effective treatment of pericardial effusion caused by uremic pericarditis in elderly patients on hemodialysis.

A 63-year-old man was referred to our hospital for rapid deterioration of his renal function. He had worked as a metal founder for more than 40 years, and had been diagnosed as having silicosis. Laboratory data on admission showed severe anemia, thrombocytopenia, and end-stage renal failure (BUN 88.8 mg/dl, serum creatinine 9.0 mg/dl). Myeloperoxidase anti-neutrophil cytoplasmic antibody(MPO-ANCA) was also detected in his sera. On the next day after admission, he complained of sudden dyspnea and hemoptysis. Mechanical ventilation with pure oxygen was insufficient to improve hypoxia without concomitant use of percutaneous cardio-pulmonary support(PCPS) and continuous hemofiltration(CHF). We diagnosed his condition as MPO-ANCA-associated rapidly progressive glomerulonephritis with diffuse alveolar hemorrhage. Treatment with plasmapheresis, pulse methylprednisolone and pulse cyclophosphamide effectively improved his hemoptysis as well as chest X-ray findings and blood gas analysis. However on his later clinical course, he was complicated with superimposed complex infection and passed away. Autopsy findings showed crescentic glomerulonephritis in the kidneys and silica nodules in the lungs. Recently it has been postulated that some relationship exists between ANCA-associated(especially MPO-ANCA-associated) glomerulonephritis and silica exposure. The reported cases of glomerulonephritis in the patients with silica exposure showed a rapidly progressive clinical course and pauci-immune necrotizing crescentic glomerulonephritis in their histology. Gregorini et al. reported that 12 of 37 (32%) male patients with RPGN had either silicosis or significant silica exposure, and 7 of 8 patients examined were ANCA-positive(6 of 7 were MPO-ANCA-positive). Therefore silica seems to cause glomerulonephritis by disrupting the immune response. Including this case mentioned above, we have experienced 10 cases of MPO-ANCA-associated glomerulonephritis, at least 3 cases out of which had suffered from silicosis in the past(30%). These results indicate that silicosis should be considered a relevant pathogen of MPO-ANCA-associated glomerulonephritis beyond the race.

Gemtuzumab ozogamicin is a humanised monoclonal IgG4 antibody, linked to a cytotoxic calicheamicin derivative. It effects cell necrosis by specifically targeting the CD33 antigen which is expressed on the surface of leukaemic cell blasts in more than 90% of patients with acute myeloid leukaemia (AML), but is not present on normal stem cells. Therapy with gemtuzumab ozogamicin (2 doses of 9 mg/m2) in 3 noncomparative studies produced complete remission in 16% of adult patients with AML in first relapse, and complete remission with incomplete platelet recovery in an additional 13% of patients. Rates of remission did not differ between those aged less than 60 years and older than 60 years. Many patients were able to receive both doses of gemtuzumab ozogamicin therapy as outpatients. Survival duration was similar between those treated as outpatients and those requiring hospitalisation. About one-third of 11 children and adolescents treated with 2 doses of 9 mg/m2 gemtuzumab ozogamicin in a phase I study showed <5% bone marrow blasts after completion of therapy. The most commonly encountered adverse events in clinical trials with gemtuzumab ozogamicin were myelosuppression, increased levels of hepatic enzymes, infection, fever, bleeding, chills, nausea and vomiting and dyspnoea. No treatment-related renal failure or alopecia was reported.

A 57-year-old man who had past history of alcoholic hepatitis was admitted to our hospital because of fever, general malaise and dyspnea. Chest X-ray films and computed tomographic scans disclosed lobar pneumonia of the right upper lobe. Laboratory tests showed hypoxemia and renal dysfunction. Artificial ventilation, endotoxin adsorption (PMX) and continuous hemodiafiltration (CHDF) were started on the day after admission because of the appearance of progressive renal failure, hypotension and disturbance of consciousness. A diagnosis of septic multiple organ failure was made on the basis of a blood and sputum culture that revealed a K. pneumoniae infection. After the initiation of intensive therapy, the patient's general condition improved and artificial ventilation, PMX and CHDF were withdrawn. However, MRSA was isolated from sputum specimens and a lung abscess developed. In spite of vancomycin administration, the effect was limited. The patient underwent a right upper lobectomy and was discharged. The prognosis of bacteremic K. pneumoniae pneumonia in alcoholics is reported to be very poor. In our case, it is suggested that PMX and CHDF contributed to the improvement of the clinical course.

We present the case of a 49 year old man who was admitted with odynophagia, fever and abdominal pain. Later he developed dyspnea and polymialgias. Pericardial effusion was detected on the echocardiogram. Renal failure and rhabdomyolysis developed worsening the clinical picture. A pericardial surgical drainage was decided due to cardiac tamponade. All samples were negative for bacteria and fungi. The presence of enterovirus in pericardial fluid was confirmed.

Ricin toxin, found in the bean of the castor plant, is one of the most toxic and easily produced plant toxin. It is composed of two polypeptide chains linked by a disulfide bond. The toxin irreversibly blocks protein synthesis. Oral intoxication is the most frequent mode of exposure, but direct contact and inhalation have also been described. A single intramuscular exposure was reported, related to an assassination event in 1978. The clinical signs of intoxication begin hours after the exposure, and include gastrointestinal signs, dyspnea, fever, vasculatory collapse, neurological signs, liver necrosis and renal failure. Treatment is mainly supportive. A vaccine has been developed and found effective in animal studies. Ricin may be used as a biological weapon due to its heat stability and worldwide availability. A more friendly use, which has been tested in clinical trials, is the incorporation of ricin-immunotoxin for the treatment of cancer patients.

The most common cause of edema of the legs and dyspnea is congestive heart failure. Further differential diagnosis such as renal or hepatic failure have to be considered. We report the case of a previous healthy 65-year-old woman who developed dyspnea and massive edema of the legs followed by acute hepatic and renal failure. Imaging studies showed a thrombosis of the inferior vena cava (IVC) caused by a tumor between the right kidney and the IVC. Histological examination revealed a leiomyosarcoma of the IVC. Hepatic failure due to venous outflow obstruction (Budd-Chiari syndrome, BCS) was diagnosed. Coagulation profile showed a complex disorder due to acute hepatic failure. Factor V Leiden and prothrombin gene mutation G20210A could be excluded. The thrombosis extended from the femoral veins up to the right atrium. After 11 days of anticoagulation with heparin platelet counts decreased by more than 50%. Suspecting a heparin-induced thrombocytopenia the patient was placed on recombinant hirudin (lepirudin) for anticoagulation. Hepatic venogram showed a thrombosis of the hepatic vein orifices but not of the hepatic veins. The tumor and the thrombi were removed surgically. When the cardiopulmonary bypass was terminated new intracardiac thrombi occurred. Despite immediate surgical intervention the patient finally died due to right ventricular failure caused by the fulminate intracardiac thrombosis. In conclusion, thrombosis of the IVC may mimic congestive heart failure and may cause BCS. Neoplasms and coagulation disorders may cause thrombosis of the IVC.
