Nineteen purebred Beagles of various ages (4, 5, 13, and 47 weeks) were inoculated with North American Trypanosoma cruzi isolates obtained from an opossum (Tc-O), an armadillo (Tc-A), or a dog (Tc-D). Dogs were grouped on the basis of clinical outcome of infection. During the acute stage of disease, dogs of group 1 (n = 7 inoculated with Tc-O or Tc-A) died or were euthanatized because of the severity of disease. Dogs of group 2 (n = 5 inoculated with Tc-O or Tc-A) developed acute disease, but survived to develop chronic disease. Dogs of group 3 (n = 7 Tc-D-inoculated dogs) developed neither acute nor chronic disease. Dogs of group 4 (n = 4--2 dogs 13 weeks old and 2 dogs 47 weeks old) served as noninoculated controls. Clinical signs associated with severe acute myocarditis developed in dogs of groups 1 and 2 between postinoculation day (PID) 15 and 28. Generalized lymphadenopathy and lymphocytosis were observed in all dogs of groups 1, 2, and 3 between PID 14 and 17. Serum alanine transaminase and aspartate transaminase activities and urea nitrogen concentration were high, and glucose concentration was low prior to death of dogs in group 1. Serum activities of isoenzymes of creatine kinase were significantly (P less than 0.05) high in only 1 dog (group 1), whereas serum lactate dehydrogenase isoenzyme activities were not significantly high in any dog.(ABSTRACT TRUNCATED AT 250 WORDS)

Haemorrhagic fever with renal syndrome (HFRS) is an acute disease caused by Hantavirus and clinically characterised by abrupt onset of fever, various haemorrhagic manifestations and transient renal and hepatic dysfunction. We retrospectively reviewed 63 cases of HFRS in children from 13 different hospitals in Korea who presented over a 15-year period. The age of the patients ranged from 7 to 15 years, with a male to female ratio of 8 to 1. Fifty-four (86%) patients were 10 years or older. On admission, 24 (38%) were in the febrile phase and 35 (56%) were in the oliguric phase. Fever (100%) abdominal pain (91%), headache (76%) and vomiting (73%) were the most common symptoms. Backache, subconjunctival haemorrhage and hypertension were also noted in about one-third of patients. Hypotension was documented in only 7 (11%) patients. Leucocytosis (> 10,000/mm3) and thrombocytopenia (< 150,000/mm3) were noted in more than two-thirds of patients. Elevated blood urea nitrogen and serum creatinine was observed in 94% by the 7th (median) day of illness. Elevated aspartate aminotransferase and/or alanine aminotransferase were found in more than two-thirds of patients. Renal biopsy was performed in 12 patients and revealed various stages of acute tubular necrosis with occasional interstitial cell infiltration and oedema. Only 2 showed evidence of interstitial haemorrhage. Eleven patients required 1-3 days of dialysis and the remaining patients required only conservative management. Three (5%) patients died of shock, respiratory failure and pulmonary haemorrhage. All other patients recovered without sequelae. Although childhood cases were much less common than adults, clinical and laboratory findings were in general similar between children and adults.

Renal function was studied in visceral leishmaniasis (VL) and post-kala-azar dermal leishmaniasis (PKDL) by means of the specific marker cystatin C and related to circulating immune complexes and cytokine production. Forty patients with VL (23 with sub-acute disease and 17 with acute disease), 17 patients with PKDL, and 22 healthy controls were included. Cystatin C, but not creatinine, was significantly raised in VL (P = 0.004). The highest levels of cystatin C were found in those with acute disease (P < 0.0001). In VL, cystatin C levels were positively correlated to circulating immune complexes and production of granulocyte-macrophage colony stimulating factor (GM-CSF), but negatively correlated to aspartate aminotransferase and lactate dehydrogenase. We conclude that cystatin C is a superior marker of glomerular function in leishmaniasis and that immune complex deposition and GM-CSF are two functions that most likely are causally involved in the mechanisms leading to glomerular dysfunction in leishmaniasis.

Following major tissue injury, hyaluronic acid production increases as a rapid response survival mechanism. Increased hyaluronic acid production and turnover are often associated with increased hyaluronidase activity, the enzyme that degrades hyaluronic acid. We investigated whether hyaluronic acid and hyaluronidase can be used as non-invasive markers of acute disease activity in hepatitis C by studying 26 patients with acute hepatitis C, 89 with chronic hepatitis C and 32 healthy controls. Chronic hepatitis C subjects were classified into five subgroups according to the stage of liver fibrosis. Serum aspartate aminotransferase and alanine aminotransferase activities and hyaluronic acid levels were increased in hepatitis C patients compared with the controls. Serum hyaluronic acid elevation correlated with disease progression. Serum hyaluronidase activities were also increased in patients compared with the controls, but decreased with disease progression. We conclude that both hyaluronidase and hyaluronic acid may be useful as early non-invasive serum indicators of disease activity in acute hepatitis C.
