Topical administration of
interferon
for locally recurrent renal cell carcinoma in 2 cases was reported. Case 1: a 56-year-old woman had undergone radical nephrectomy for left renal cell carcinoma. She had a locally recurrent tumor adjacent to spleen 26 months after the surgery. She received 3 million units of interferon alpha every day intralesionally for almost 3 years without any distant metastasis. Case 2: a 59-year-old man had undergone left radical nephrectomy for renal cell carcinoma. He had recurrent tumor contiguous to spleen 24 months after nephrectomy. With Seldinger method a catheter was indwelled selectively in splenic artery. Two million units of interferon gamma was administered through the catheter, twice a week for 4 weeks, and once a week in subsequent course. The tumor showed necrosis on CT film. He died of
DIC
5 months after the initiation of intraarterial administration of interferon gamma. Topical use of
interferon
showed some favorable effects in both cases even after the failure of systemic administration. Further investigation is warranted to demonstrate the advantage of topical use of
interferon
over systemic administration.

Rhesus monkeys inoculated intravenously with Rift Valley fever (RVF) virus presented clinical disease syndromes similar to human cases of RVF. All 17 infected monkeys had high-titered viremias but disease ranged from clinically inapparent to death. Three (18%) RVF virus-infected monkeys developed signs of hemorrhagic fever characterized by epistaxis, petechial to purpuric cutaneous lesions, anorexia, and vomiting prior to death. The 14 remaining monkeys survived RVF viral infection but, 7 showed clinical signs of illness characterized by diminished food intake, cutaneous petechiae, and occasional vomiting. The other 7 monkeys showed no evidence of clinical disease. All monkeys had detectable serum
interferon
24-30 h after infection, but 4 of 7 monkeys that did not develop clinical illness had serum
interferon
titers within 12 h after infection. In lethally infected macaques, indices of hepatic function and blood coagulation were abnormal within 2 days, implicating early pathogenetic events as critical determinants of survival. Serum transferase values were elevated in proportion to severity of clinical disease and outcome of infection. Both myocardial damage and laboratory evidence consistent with
disseminated intravascular coagulation
were present in fatal infections. All surviving monkeys developed neutralizing antibodies to RVF virus 4-7 days after infection, and this coincided with termination of viremia. Two fatally infected monkeys were viremic until death on days 6 and 8, and the third cleared viremia on day 5 and developed antibody on day 6 but died on day 15. There was a significant correlation between a delayed
interferon
response and mortality, suggesting that the early appearance of
interferon
was influential in limiting the severity of disease.

Although many viral infections have on occasion been associated with hemorrhagic complications, infection with any of several RNA viruses regularly results in vascular involvement and the syndrome called viral hemorrhagic fever (VHF). In spite of clinically useful similarities among various VHFs, there are significant differences in their pathogenesis and clinical evolution; these are often related to characteristics of their viral taxon. Infection with Rift Valley fever (RVF) virus, a phlebovirus, appears to be regulated by
interferon
and terminated by neutralizing antibody. In contrast, Lassa fever (LF) virus, an arenavirus, is resistant to
interferon
, and LF is terminated by cellular immune effector mechanisms. The lytic virus-cell interaction typical of RVF virus suggests its major effects occur by direct, virus-induced cellular necrosis, particularly in the liver. In the primate RVF model,
disseminated intravascular coagulation
(
DIC
) may be important. LF virus--characteristically noncytopathic--may exert its effects through induction of mediator secretion from infected macrophages.
DIC
does not appear to be a central pathogenetic mechanism in LF. Pichinde virus, which is not pathogenic for humans, provides an alternate model for study of LF. Infected guinea pigs do not show histologic lesions that could explain their body wasting, cardiovascular deterioration, and pulmonary edema. In the heart, for example, loss of tissue mass, protein, and contractile function proceed without direct viral involvement or myocarditis. Sulfidopeptide leukotrienes have been implicated as one relevant soluble mediator participating in the disease state.

An unusual case of Q fever in a 62-year-old female is described. The patient presented with severe pneumonia and developed renal failure,
disseminated intravascular coagulation
and pancytopenia which recurred after antibiotics were discontinued. Subsequently hairy cell leukemia was diagnosed and evolved favorably under treatment with doxycycline and alpha-
interferon
. A review of the literature confirms that renal failure and
disseminated intravascular coagulation
do not appear to be associated with Coxiella burnetti infections, nor has the association of Q fever and hairy cell leukemia been previously described.

Giant vascular neoplasms in neonates generally require aggressive medical or surgical therapy for treatment of complications. Steroids, chemotherapy, embolization, radiation, and surgery have all been used with short-term beneficial and sometimes unknown long-term side effects. A new modality of treatment, alpha-
interferon
, has recently been described. The majority of hemangiomas in children involute by 8 years of age. Occasionally, hemangiomas can endanger vital structures and are associated with a
consumption coagulopathy
and thrombocytopenia (Kasabach-Merritt Syndrome). These hemangiomas occasionally do not respond to steroids, radiation therapy, cytotoxic drugs, or embolization. The mortality rates approach 50% in nonresponders. Alpha-
interferon
has been used in these children with life-threatening complications of hemangiomas with relief of symptoms. This case illustrates the potential use of alpha-
interferon
in the management of giant hemangiomas in children. This emerging form of biological therapy avoids the risks of radiation therapy, embolization, and surgery with only minimal side effects.

A 59-year-old woman developed edema of the face and eyelids during
interferon
(
IFN
)-alpha-2b therapy for chronic hepatitis C with a cumulative dose of 6 million x 47 units. Despite cessation of the therapy, the edema progressed and was followed by exophthalmos, pyrexia, liver dysfunction, pancytopenia, and
disseminated intravascular coagulation
. Two months after initial presentation, she died of hemorrhagic shock and was diagnosed with histiocytic cytophagic panniculitis at autopsy. This may be a hitherto unrecognized adverse effect of therapeutic
IFN
alpha.

We present an adult patient with haemophagocytic syndrome (HPS) successfully treated with a combination of steroid pulse therapy and double filtration plasmapheresis (DFPP). A 58-year-old male was admitted with high fever, severe renal dysfunction, liver dysfunction and an increased level of lactate dehydrogenase. A serological test for Epstein-Barr (EB) virus showed an elevation of EBNA-IgM antibody titre. There were increased haemophagocytic histiocytes in the bone marrow in addition to thrombocytopenia and
disseminated intravascular coagulation
(
DIC
) accompanied by organ dysfunction. EB virus associated haemophagocytic syndrome was diagnosed. On admission,
interferon
(
IFN
)-gamma, interleukin (IL)-6, IL-8, granulocyte colony-stimulating factor (G-CSF) and macrophage (M)-CSF were elevated, and were promptly normalized after steroid pulse therapy was initiated. G-CSF and M-CSF gradually decreased after DFPPs was started. To control hypercytokinaemia until treatment for the underlying disease is initiated, steroid pulse therapy and double filtration plasmapheresis are useful.

An 11-year-old boy was diagnosed as having acute lymphoblastic leukemia (ALL, L1) in 1987 and underwent treatment with an ALL high-risk protocol (prednisolone, vincristine (VCR), daunorubicin, 1-asparaginase), which resulted in complete remission. In 1990 he developed chronic hepatitis C and received
interferon
therapy. In December 1994, ALL recurred, and the patient was treated with VCR. He subsequently developed severe hemolysis (Hb 12.5 g/dl-->6.8 g/dl) with increases of indirect bilirubin, AST, and LDH. Furthermore, symptoms resembling a syndrome of inappropriate secretion of ADH (SIADH) and
DIC
developed. Upon incubation of the patient's red blood cells with VCR in vitro, extreme deformity of the cells was observed. These findings suggested that splenomegaly, due to liver cirrhosis which had developed rapidly from chronic hepatitis C while the patient was in an immunosuppressed state induced by anticancer drugs, had trapped the deformed red blood cells and resulted in severe hemolysis. The patient died on the 165th day after admission due to liver failure.

African swine fever (ASF) is an asymptomatic infection of warthogs and bushpigs, which has become an emergent disease of domestic pigs, characterized by hemorrhage, lymphopenia, and
disseminated intravascular coagulation
. It is caused by a large icosohedral double-stranded DNA virus, African swine fever virus (ASFV), with infection of macrophages well characterized in vitro and in vivo. This study shows that virulent isolates of ASFV also infect primary cultures of porcine aortic endothelial cells and bushpig endothelial cells (BPECs) in vitro. Kinetics of early and late gene expression, viral factory formation, replication, and secretion were similar in endothelial cells and macrophages. However, ASFV-infected endothelial cells died by apoptosis, detected morphologically by terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling and nuclear condensation and biochemically by poly(ADP-ribose) polymerase (PARP) cleavage at 4 h postinfection (hpi). Immediate-early proinflammatory responses were inhibited, characterized by a lack of E-selectin surface expression and interleukin 6 (IL-6) and IL-8 mRNA synthesis. Moreover, ASFV actively downregulated
interferon
-induced major histocompatibility complex class I surface expression, a strategy by which viruses evade the immune system. Significantly, Western blot analysis showed that the 65-kDa subunit of the transcription factor NF-kappaB, a central regulator of the early response to viral infection, decreased by 8 hpi and disappeared by 18 hpi. Both disappearance of NF-kappaB p65 and cleavage of PARP were reversed by the caspase inhibitor z-VAD-fmk. Interestingly, surface expression and mRNA transcription of tissue factor, an important initiator of the coagulation cascade, increased 4 h after ASFV infection. These data suggest a central role for vascular endothelial cells in the hemorrhagic pathogenesis of the disease. Since BPECs infected with ASFV also undergo apoptosis, resistance of the natural host must involve complex pathological factors other than viral tropism.

Rhabdomyolysis is an unusual complication of chemotherapy that can lead to substantial morbidity through such complications as renal failure, infections, and
disseminated intravascular coagulation
. The syndrome has been described after treatment with cyclophosphamide, 5-azacytidine, interleukin-2, and
interferon
and after bone marrow transplantation. We report a patient with acute myeloid leukemia who developed fulminant rhabdomyolysis after treatment with a cytarabine-containing regimen. The syndrome was complicated by acute renal failure requiring hemodyalisis, respiratory insufficiency, and pancreatitis. We suggest that the muscle damage might be related to the known ability of cytarabine to trigger the release of cytochrome c from the mitochondria, which could lead to uncoupling of the oxidative phosphorylation with subsequent depletion of ATP reserves at the skeletal muscle and rhabdomyolysis.
