During the last several years, there has been increasing interest in the use of intravenous immune globulin for immunosuppression. Although the mechanism(s) of action remains to be delineated, immune globulin therapy has been shown to be effective in some antibody-mediated disorders. In Rh disease, antibody-induced cytopenias, myasthenia gravis, and the clotting disorder associated with anti-factor VIII antibody, intravenous immune globulin has had therapeutic benefit. It was of interest that intravenous immune globulin may partially ameliorate the tendency toward dilation of the coronary vessels in Kawasaki disease. If this disorder represents a vasculitis of the small feeding vessels of the coronary arteries, could this agent influence other forms of collagen vascular disease? Pilot studies in dermatomyositis and polymyositis and systemic juvenile rheumatoid arthritis indicate benefit from intravenous immune globulin therapy. In these studies we used a high-dose protocol consisting of 1 gm/kg/day of immune globulin for 2 days every 4 weeks. In patients with either myositis or systemic juvenile rheumatoid arthritis, beneficial effects were seen. In the former group of patients, increased proximal muscle strength and reduction in creatine kinase levels were observed. In the latter group of patients a marked reduction in systemic features was observed. The amount of corticosteroids required was reduced in both groups of patients. These studies indicate the potential for intravenous immune globulin in collagen vascular disorders and the need for carefully controlled trials of this form of therapy.

Six horses had been admitted to the hospital because of illness other than renal failure; diarrhoea, myositis, abdominal pain and/or suspected bacterial sepsis. Hypotension and disseminated intravascular coagulopathy were frequent findings in the horses. Abnormally high serum creatinine concentration and urine specific gravity of less than 1.022 were found in the horses with acute renal failure. Hyponatraemia and hypochloraemia were the most common abnormal electrolyte findings. Pronounced hyperkalaemia was not found. Variable degrees of tubular necrosis were seen in three of the four horses that had kidney sections submitted for microscopic examination. Renal cortical necrosis occurred in one horse. Intravenous fluid and electrolyte replacement was the most important therapy in those cases that were non-oliguric. Furosemide, mannitol and dopamine were used in horses with oliguria. The prognosis was generally good if the predisposing cause could be corrected and the acute renal failure was not oliguric.

Two Japanese cases of streptococcal toxic shock syndrome (STSS) are reported. The first patient was a 45-year-old male who developed necrotizing fasciitis and myositis of the left thigh, refractory hypotension, hepatic dysfunction and acute renal failure; the patient died despite treatment. Streptococcus pyogenes was isolated from the inflamed fascia. The second patient was a 69-year-old female who had coagulopathy, polymyositis and hepatic function abnormality. Streptococcus pyogenes was isolated from blood culture. She was immediately placed on high-dose ampicillin as well as other supportive measures, and she survived.

A case of streptococcal toxic shock like syndrome occurring in a 44-year-old previously healthy Japanese male is reported. He initially had a sore throat, low grade fever, diarrhea and mild pains in a lower extremities. Shortly thereafter, he rapidly developed a high fever, profound hypotension, multifocal epidermal necrosis, and sever purulent fasciitis and myositis in both lower extremities, which required above knee amputation of both legs. He later developed disseminated intravascular coagulopathy, adult respiratory distress syndrome, acute renal failure, coma and necrotizing inflammation of both arms and external genitalia despite treatment. He died on the 13th hospital day. Streptococcus pyogenes was isolated from the necrotic muscles and right knee joint. The organism was typed as M3, T3, was sensitive to penicillins, and was found to be producing streptococcal pyogenic exotoxin A in vitro. This is the first case report of streptococcal toxic shock like syndrome in Japan.

Several reports over the past 15 years describe severe group A streptococcal infections causing septic shock, soft-tissue necrosis, and multiple organ failure; a phenomenon known as streptococcal toxic shock-like syndrome (TSLS). However, primary peritonitis associated with TSLS is rare. We report the case of a 40-year-old man admitted with pain in both thighs, hypotension, and severe abdominal pain. His daughter had been diagnosed with streptococcal pharyngitis 3 days earlier. We performed an emergency laparotomy for peritonitis, and culture of the ascites was positive for group A beta -hemolytic streptococcus (GAS). Further serotyping of the isolated GAS strain revealed the T-type 22 and the pyrogenic exotoxin gene, spe-C. The criteria for TSLS were clearly met, including the isolation of GAS from ascites, hypotension, liver failure, renal failure, coagulopathy, myositis, and a generalized erythematous macular rash with desquamation.

Dengue hemorrhagic fever is caused by dengue virus infection. The classical manifestations consist of fever, thrombocytopenia, and hemoconcentration. However, its unusual complications may be fatal, such as prolong shock, massive bleeding, volume overload, and unusual manifestations, for example, severe rhabdomyolysis. Here we report a case of 17-year old Thai man who was referred to our hospital because of 7-day fever with thrombocytopenia, hemoconcentration and right pleural effusion. The serology tests confirmed to be dengue infection. He developed various complications: severe hepatitis, coagulopathy, and heavy proteinuria; encephalopathy that needed a respiratory ventilator. On day 12 of fever, he had myalgia and passed dark urine. Serum creatinine and serum creatinine phosphokinase (CPK) were found abnormally high. He was diagnosed as severe rhabdomyolysis with acute kidney injury, and immediate hemodialysis was performed. He did not respond to treatment and expired within three hours. Although the mechanism of severe rhabdomyolysis in dengue fever is not clearly known, it may theoretically be proposed such as direct muscle cell injury leading to myositis by dengue virus, myotoxic cytokines which are produced in response to viral infection, dehydration or hypophosphatemia.
