We present a case of meningoencephalitis due to EBV in a 2-month-old infant, without mononucleosis, which persisted for more than 5 months. Evidence for persistence of the infection was provided by a convulsive disorder and prolonged CSF pleocytosis, combined with persistent moderate anemia. Despite the persistence of the infection, the child continued to develop normally. This case demonstrates that EBV meningoencephalitis occurring in young patients may present with only subtle clinical findings and may have a favorable prognosis.

A young man developed infectious mononucleosis complicated by profound anaemia due to haemolysis. The Donath Landsteiner antibody was found in his serum. He was treated successfully by blood transfusion but subsequently developed severe neutropenia. Both complications have been reported previously but not in the same individual. No underlying immune deficiency could be identified.

The actuality of a problem of cytomegaloviral infection in military transfusiology is substantiated by the increasing number of immunocompromised recipients, mass use of hemocomponent therapy in prophylaxis and correction of anemia, thrombohemorrhagic and immunodeficient syndromes. Cytomegaloviral infection in the recipients of hemocomponents may have unfavourable consequences, such as the development of mononucleosis, enhanced sensitivity to opportunistic infectious agents as a result of virus-induced immunodepression, graft rejection, risk of the development of oncologic diseases, atherosclerosis, disorders in the processes of reparation and regeneration. In the northwestern part of Russia the cytomegaloviral antigens are disclosed in 65-75% of men, age 18-23. Actual tasks are the following: put into practice cytomegaloviral antigens test for donors, make a wide use of effective leukocytic filters for leukocyte removal from hemotransfusional medium, minimize posttransfusion immunosuppression, determine recipients who need transfusions of hemocomponents prepared from seronegative donors.

This article presents basic information on the clinical features of HIV infection, most of which are related to the profound immune deficiency associated with HIV/AIDS. Primary HIV infection is associated with clinical symptoms, primarily a mononucleosis syndrome, in about 50% of cases. In the ensuing 10 years, more than 50% of HIV-infected individuals develop the opportunistic infections (OIs) indicative of the onset of AIDS. Common presentations of AIDS include pneumonia, dysphagia, diarrhea, neurologic symptoms, fever, wasting, anemia, and vision loss. Monitoring of peripheral blood CD4 T-lymphocytes provides a measure of the current risk of OIs and a guide for antiretroviral therapy. Protease inhibitors, used in combination with other antiretrovirals, allow long-term control of HIV disease, but the substantial cost of these drugs has prohibited their widespread use in developing countries. Treatment of HIV-related infections must be followed by a maintenance regimen intended to prevent relapse.

This chapter presents an introduction to several diseases of the blood including infectious mononucleosis, leukemia, thrombosis and coagulation, bone marrow disorders, malaria, and anemia. In addition a survey of the recent literature is presented relative to natural products that have been utilized for the treatment of these diseases. The natural products that are reported represent a wide range of structural types and present interesting mechanisms of action. Thus the possibility exists that new drugs may be developed from these natural products which are more effective than those currently on the market.

Infectious mononucleosis caused by Epstein-Barr virus (EBV) usually resolves over a period of weeks or months without sequelae but may occasionally be complicated by a wide variety of neurologic, hematologic, hepatic, respiratory, and psychological complications. The strength of association of EBV with many of these complications remains based on scattered case reports, often using unsophisticated diagnostic tests, and the evidence for causation in many instances is unconvincing. There is little benefit of antiviral treatment of uncomplicated or complicated infectious mononucleosis. Corticosteroids may have a role in hastening resolution of some complications, especially upper airway obstruction and possibly immune-mediated anemia and thrombocytopenia, but should be used judiciously.

Previous studies have suggested a relationship between reproductive history, pregnancy and birth factors, and the risk of neuroblastoma. We conducted a case-control telephone interview study that included a total of 504 children under the age of 19 years with newly diagnosed neuroblastoma identified by two national collaborative clinical trials groups, the Children's Cancer Group and the Pediatric Oncology Group. A total of 504 controls, matched to cases on age, were identified by random digit dialing. Conditional logistic regression was used to estimate the matched odds ratio (OR) and 95% confidence interval (CI) with adjustment for household income, and maternal race and education. In addition, case subgroups defined by age at diagnosis, tumour MYCN oncogene amplification status, and stage were evaluated. A suggestive pattern of increased risk was seen for a greater number of prior pregnancies, history of previous miscarriages and induced abortions, with nearly a twofold increase in risk for two or more prior induced abortions (OR = 1.9, 95% CI [1.0,3.7]). No association was found for the following diseases or conditions during pregnancy: hepatitis, rubella, measles, mumps, chickenpox, mononucleosis, vaccinations, morning sickness, pre-eclampsia, bleeding, proteinuria, anaemia, urinary tract infections, heart disease, kidney disease, liver disease and diabetes. A weak association was found for hypertension during pregnancy. Several labour and delivery factors were related to an increased risk, including threatened miscarriage, anaesthetic during labour (specifically epidural) and caesarean delivery. We found associations between premature delivery (<33 weeks: OR = 1.9, 95% CI [0.7,4.8]), very low birthweight (<1500 g: OR = 2.6, 95% CI [0.7,10.3]) and risk of neuroblastoma. There was no consistent pattern of increased risk found for most factors within subgroups defined by age at diagnosis, stage or MYCN status.

Chronic infection with Epstein-Barr virus (EBV) without previous immunodeficiency or immuno-suppressive therapy is relatively rare. Severe chronic active EBV (SCAEBV) infection was reported for the first time in 1984 as 'chronic mononucleosis syndrome', and diagnostic criteria were proposed. It is characterized by clinical features including fever, severe hepatosplenomegaly, lymphadenopathy, hematologic features such as anemia and thrombocytopenia, and elevated antibody titers to EBV. We experienced a 21-year-old woman who initially presented with fever and chronic fatigue; however, no definite diagnosis could be made at the time of admission. Three months after the initial admission, there was evidence of only splenomegaly and the patient had persistent, multiple, paraaortic lymphadenopathies in abdominal CT. Diagnostic splenectomy was performed, and SCAEBV infection with T-cell lymphoproliferative disorder was ultimately diagnosed.

In this study, the clinical and laboratory features of 26 infectious mononucleosis (IMN) cases who have been diagnosed between the years of 1984-2005 were evaluated retrospectively. The mean age of the patients was 26+/-11 years, the rate of being hospitalized was 65%, and mean hospitalization period was 9.2+/-6 days. Fever (81%), weakness (50%), sore throat (50%), headache (50%) and swollen neck (35%) were the most common symptoms, while in the physical examination cervical lymphadenopathy (81%), splenomegaly (69%), hyperemic pharynx (65%), hepatomegaly (54%) and tonsillitis (50%) were observed. Laboratory results yielded leukocytosis in 21%, leucopenia in 12%, anemia in 44%, thrombocytopenia in 5% and elevated transaminase levels in 84% of the patients. Of the patients 15 (57.7%) had the history of using antibiotics before the diagnosis. Serological diagnosis was performed by Paul-Bunnel test and/or IgM positivity against Epstein-Barr virus (EBV) viral capsid antigen (VCA). Tonsillo-pharyngitis secondary to edema and respiratory distress due to lymphadenopathy pressure were detected in four patients, whereas pancytopenia was established only in one patient, as complications. This study emphasized that, although IMN is a self-limited infection, the diagnostic difficulties may arise when the clinical course is atypical, and rarely seen life-threatening complications may also develop during IMN course.

Viral loads and cytokine responses Epstein-Barr virus (EBV) were measured in an 18-year-old boy with severe glandular fever complicated by a mild anaemia, severe thrombocytopaenia and neutropaenia. Hepatosplenomegaly was detected by abdominal ultrasound in the presence of significant hepatitis. Cytokine testing demonstrated elevated cell-mediated Th1 (IFN-gamma, IL-12, sTNFR1, CXCL10, CXCL9 and CCL3) and humoral Th2 (IL-4) immune responses. Serum antibodies to EBV virus capsid antigen (VCA) IgM and IgG antibodies were detected, together with a raised EBV DNA level (up to about 70,000 DNA copies/mL) in the acute phase of the illness. This EBV DNA load decreased rapidly in response to treatment with a combination of foscarnet, intravenous immunoglobulin and prednisolone, and the boy's symptoms settled eventually after approximately 50 days of illness, following this combined antiviral and immune-modulating therapy. Detailed immunological, virological, haematological and biochemical laboratory parameters are presented to document this patient's severe EBV disease and eventual recovery.
