Flurbiprofen, a potent non-steroidal anti-inflammatory and antipyretic agent, was given as an intravenous infusion (2 mg/kg) followed by a bolus injection of 1 mg/kg six hours later. After drug administration body temperature and rumen contractions were slightly depressed, whereas urea values gradually increased; serum sorbitol dehydrogenase (SDH) activity, plasma iron concentration and the number of circulating lymphocytes were significantly lower. Intravenous injection of endotoxin from Escherichia coli O111B4 (0.1 microgram/kg) caused shivering, fever, inhibition of rumen contractions, changes in heart rate, lymphopenia, neutropenia followed by neutrophylic leucocytosis, changes in urea values, hypoferraemia, hypozincaemia and a decline in serum alkaline phosphatase (ALP) activity, whereas gamma-glutamyltranspeptidase, glutamic oxalacetic transaminase, lactic dehydrogenase and SDH values were not significantly altered. Pretreatment with flurbiprofen completely abolished the febrile reactions to endotoxin. The endotoxin-induced inhibition of rumen contractions was only delayed. The drug blocked the initial tachycardia to endotoxin but did not prevent the secondary biphasic increase in heart rate. Flurbiprofen failed to modify the endotoxin-induced decrease in both plasma zinc and serum ALP activity whereas the decline in plasma iron concentration was delayed. After drug pretreatment the changes in circulating white blood cells were more pronounced. These data demonstrate that most of the haematological, blood biochemical and clinical effects of endotoxin cannot be blocked by flurbiprofen, and that these effects are not due to the increase in body temperature alone. Tolerance induced by repetitive daily intravenous administration of endotoxin resulted in an almost complete abolition of all the effects. However, the plasma iron values from tolerant goats were significantly lower than those from non-tolerant animals, which demonstrates that the development of a refractory state can result in modification of this biochemical parameter.

Infection of naive North American horses with 10(4) cell culture infectious doses (CCID50) of virulence variants of African horsesickness virus (AHSV), designated AHSV/4SP, AHSV/9PI, and AHSV/4PI, reproduced three classical forms of African horsesickness: acute (pulmonary), subacute (cardiac), and febrile, respectively. Distinct clinicopathologic and hemostatic abnormalities were associated with each form of disease. Hemostatic abnormalities included increased concentration of fibrin degradation products and prolongation of prothrombin, activated partial thromboplastin, and thrombin clotting times. Hemostatic findings indicated activation of the coagulation and fibrinolytic systems with clotting factor consumption in acute and subacute cases of African horsesickness. Hematologic abnormalities in acute and subacute cases of African horsesickness included leukopenia, decreased platelet counts, elevated hematocrit, and increased erythrocyte counts and hemoglobin concentration. Leukopenia was characterized by lymphopenia, neutropenia, and a left shift. Increased levels of serum creatine kinase, lactate dehydrogenase, aspartate aminotransferase, and alkaline phosphatase, hypocalcemia, hypoalbuminemia, hypoproteinemia, and elevated creatinine, phosphorus, and total bilirubin levels were present in some but not all horses. Metabolic acidosis, indicated by decreased total bicarbonate and increased lactate and anion gap, was present in horses with the acute form of disease. Mild thrombocytopenia and leukopenia were occasionally associated with the febrile form of disease. These results suggest a role for intravascular coagulation in the pathogenesis of African horsesickness.

We analyzed 33 patients with AILD T-NHL in a retrospective multicentric study. The median age was 62 yr (35-84 yr) (19 patients over 60 yr). Advanced disease (n = 31) and B-symptoms were consistently found (n = 29) and 20 patients had bone marrow involvement. The main laboratory abnormalities were: anemia (n = 13), hypereosinophilia (n = 13), lymphopenia (n = 14), hypergammaglobulinemia (n = 17), elevated lactate dehydrogenase (LDH) level (n = 24). First-line therapy was chemotherapy (ChT) alone (n = 25) or ChT after steroids (n = 8). Most patients received a CHOP-like regimen for a median number of 6 cycles and 3 patients received interferon alpha (IFN alpha) as consolidation after chemotherapy. With a median follow-up of 46 mo, 60% achieved a complete response but the outcome was poor with a relapse rate at 56%, a median survival referring to the total population was of 36 mo (2-108+ mo) and an overall survival at 5 yr of 36%. Two patients received high-dose chemotherapy (with total body irradiation) and autologous progenitor-cell transplantation for chemosensitive relapse and were free of disease at, respectively, 76 and 24 mo+. In conclusion AILD T-NHL still has a poor prognosis compared to other NHL. The role of intensive therapy and IFN alpha still remains to be evaluated.

Acute renal failure due to diffuse renal infiltration is rarely the presenting manifestation of non-Hodgkin's lymphoma. We report a patient with acute renal failure secondary to diffuse bilateral renal infiltration by a Burkitt's lymphoma. The presence of bilateral renal enlargement, an elevated serum lactate dehydrogenase (LDH), and lymphopenia should suggest the diagnosis, which can be confirmed by renal biopsy.

The mysterious severe acute respiratory syndrome (SARS) that has originated from the southern Chinese province of Guangdong appears to be a major public health threat and medical challenge. Laboratory studies of SARS patients in a number of countries identified the etiologic agent being a novel member of coronaviridae. High RNA concentrations of this virus in sputum make it as a highly infectious agent. Low concentrations of viral genome are also detectable in feces. Coronaviruses are ubiquitos. They cause disease in many animals including pigs, cattle, dogs, cats, and chickens. These viruses have been associated with upper respiratory infections and sometimes pneumonia in humans. SARS presents with fever, cough, malaise, dyspnea, and hypoxemia. Chest radiographs from affected regions are associated with progressive airway disease. Clinical laboratory features of SARS include lymphopenia, thrombocytopenia, and elevated lactate dehydrogenase levels. Currently, there is no FDA approved pharmacologic treatment for SARS. To date, no convincing clinical data is available for treatment of SARS with ribavirin. While there are some controversies about the use of systemic corticosteroids, Martin et al, in this issue of MSM, present their views on the use of pentoxyfylline (PTX) as a potential agent to be considered for SARS treatment. Finally, our analytical approach to the risks of SARS will certainly enable us to

A 68-year old Japanese male with alcohol related rhabdomyolysis, hepatitis, and hematological disorders is presented. Biochemical data showed markedly elevated levels of serum hepatobiliary enzymes, lactate dehydrogenase and myoglobin, and decreased levels of serum sodium and phosphate. The serum creatine kinase level was approximately 40 times higher than the normal upper limit with 97% of MM fraction. Clinical manifestations of rhabdomyolysis, such as myalgia, muscle weakness and acute renal failure, were not recognized. Hematological examinations revealed mild neutropenia, lymphopenia, monocytopenia and thrombocytopenia but no anemia or macrocytosis. Initial treatment of an intravenous infusion of saline (30 mL/Kg body weight) and subsequent low sodium diet was successfully completed without severe complications. All the abnormal laboratory data were normalized within three weeks of his hospitalization. We suggest that hyponatremia and hypophosphatemia may be involved in the development of rhabdomyolysis, hepatitis and hematological disorders.

From April 18 to May 31, 2003, 46 patients with probable severe acute respiratory syndrome were admitted to the negative-pressure isolation rooms of Mackay Memorial Hospital in Taipei, Taiwan. Their demographic, clinical, laboratory, and radiologic characteristics and clinical outcomes were analyzed. There were 15 males and 31 females, in this cohort, 13 of whom were healthcare workers. The latter included 6 hospital staff and 7 medical personnel transferred from other hospitals. The most common symptoms were fever (100%, 46/46), cough (72%, 33/46), shortness of breath (46%, 21/46), and diarrhea (39%, 18/46). Other common findings were lymphopenia (57%, 26/46), thrombocytopenia (39%, 18/46), elevated lactate dehydrogenase (63%, 29/46), and elevated creatine kinase (24%, 11/46). A total of 7 patients (15%) required mechanical ventilation, and 8 (17%) died. Advanced age was an independent significant risk factor for death. Fever followed by rapidly progressive respiratory compromise led to significant morbidity and mortality in this cohort.

Severe acute respiratory syndrome (SARS) is a highly infectious disease with a significant morbidity and case fatality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache and dyspnoea. Less common symptoms include sputum production, sore throat, coryza, dizziness, nausea, vomiting and diarrhoea. Older subjects may present with decrease in general well-being, poor feeding, fall/fracture and delirium, without the typical febrile response. Common laboratory features include lymphopenia with depletion of CD4 and CD8 lymphocytes, thrombocytopenia, prolonged activated partial thromboplastin time, elevated D-Dimer, elevated alanine transminases, lactate dehydrogenase and creatinine kinase. The constellation of compatible clinical and laboratory findings, together with the rather characteristic radiological features especially on HRCT and the lack of clinical response to broad-spectrum antibiotics, should quickly arouse suspicion of SARS. The positivity rates of urine, nasophargyngeal aspirate and stool specimen have been reported to be 42%, 68% and 97%, respectively, on day 14 of illness, whereas serology for confirmation may take 28 days to reach a detection rate above 90%. Recently, quantitative measurement of blood SARS CoV RNA with real-time RT-PCR technique has been developed with a detection rate of 80% as early as day 1 of hospital admission but the detection rates drop to 75% and 42% on day 7 and day 14, respectively.

Clinical and laboratory data on severe acute respiratory syndrome (SARS), particularly on the temporal progression of abnormal laboratory findings, are limited. We conducted a prospective study on the clinical, radiologic, and hematologic findings of SARS patients with pneumonia, who were admitted to National Taiwan University Hospital from March 8 to June 15, 2003. Fever was the most frequent initial symptom, followed by cough, myalgia, dyspnea, and diarrhea. Twenty-four patients had various underlying diseases. Most patients had elevated C-reactive protein (CRP) levels and lymphopenia. Other common abnormal laboratory findings included leukopenia, thrombocytopenia, and elevated levels of aminotransferase, lactate dehydrogenase, and creatine kinase. These clinical and laboratory findings were exacerbated in most patients during the second week of disease. The overall case-fatality rate was 19.7%. By multivariate analysis, underlying disease and initial CRP level were predictive of death.

Severe acute respiratory syndrome (SARS) is a newly emerged infectious disease with a significant morbidity and mortality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache, and dyspnoea. Older subjects may present without the typical febrile response. Common laboratory features include lymphopenia, thrombocytopenia, raised alanine transaminases, lactate dehydrogenase, and creatine kinase. The constellation of compatible clinical and laboratory findings, together with certain characteristic radiological features and lack of clinical response to broad spectrum antibiotics, should arouse suspicion of SARS. Measurement of serum RNA by real time reverse transcriptase-polymerase chain reaction technique has a detection rate of 75%-80% in the first week of the illness.
