Chronic bone marrow failure due to persistent B19 parvovirus infection.

Abstract: The B19 parvovirus, which was serendipitously discovered in serum from blood-bank donors in 1975,1 has been associated with several human illnesses. B19 is the etiologic agent of the common childhood exanthem called fifth disease.2 Adults with fifth disease more commonly present with polyarthralgia than skin eruption, and B19 infection has frequently been detected in patients presenting with acute joint symptoms.3 , 4 In patients with underlying hemolysis, B19 infection is the cause of transient aplastic crisis, in which cessation of erythropoiesis leads to absolute reticulocytopenia and abrupt worsening of anemia.5 , 6 In utero infection with B19 has been associated with spontaneous abortion.7 8 9 Laboratory . . .

Acyclovir Halts Progression of Herpes Zoster in Immunocompromised Patients

Abstract: We conducted a placebo-controlled, double-blind study of acyclovir therapy for acute herpes zoster in immunocompromised patients. Of the 94 patients enrolled in the study, 52 had localized skin lesions at entry, and 42 had disseminated cutaneous zoster. A one-week course of intravenous acyclovir (1500 mg per square meter of body-surface area per day) halted progression of zoster in both groups, as determined by development or progression of cutaneous dissemination, development of visceral zoster, or proportion of cases deemed treatment failures. Significantly fewer patients treated with acyclovir within the first three days after the onset of exanthem had complications of zoster, as compared with patients treated with placebo (P = 0.02 by Fisher's exact test), but acyclovir also stopped progression of zoster in patients treated after three days of rash (P = 0.05 by Fisher's exact test). Acyclovir recipients with disseminated cutaneous zoster had a significantly accelerated rate of clearance of virus from vesicles, as compared with placebo recipients (P = 0.05 by the Breslow test).

Fatal Encephalitis Due to Variant B Human Herpesvirus-6 Infection in a Bone Marrow-Transplant Recipient

Abstract: Human herpesvirus-6 (HHV-6) is the causative agent of exanthem subitum1 and febrile illnesses2 in children. More recently, HHV-6 has been shown to infect the recipients of bone marrow transplants and has been implicated in interstitial pneumonitis3,4 and bone marrow suppression5 after transplantation. The pathogenicity of HHV-6, however, has yet to be fully delineated in either immunocompetent or immunocompromised hosts. In some children with exanthem subitum, seizures, encephalopathy, and the detection of HHV-6 DNA in cerebrospinal fluid have provided circumstantial evidence that HHV-6 can infect the central nervous system6,7. Nevertheless, these studies have failed to document the direct . . .
