We describe 2 patients with prolonged autoimmune alterations following parvovirus B19 infection. B19 induced aplastic crises were the revealing manifestations of asymptomatic hemolytic conditions in the 2 patients: a Coombs' positive hemolytic anemia induced by D-penicillamine in the first and congenital spherocytosis in the second. Both patients had transient clinical and serological manifestations highly suggestive of systemic lupus erythematosus. In addition, prolonged clinical and serological remission of rheumatoid arthritis was observed in the first patient, while arthralgias, FANA, and anti-Ro antibodies persisted in the second, previously healthy patient. Our data suggest that parvovirus B19 infection may lead to chronic modulation of the autoimmune response in predisposed individuals.

Human Parvovirus B19 (PB19) may cause joint manifestations. We report eight cases of polyarthritis associated with PB19 IgM: six cases of acute polyarthritis spontaneously resolving within a few days, and two other cases suggesting that PB19 should be responsible for accutisation of chronic disease (lupus with Kikuchi's disease and HLA B27 related arthritis).

Twenty-one serum samples from 18 wolves (Canis lupus) were collected from 1985 to 1990 from northwestern Montana (USA) and southeastern British Columbia, Canada, and evaluated for antibodies to canine parvovirus (CPV), canine distemper (CD), infectious canine hepatitis, and Lyme disease; we found prevalences of 13 (65%) of 19, five (29%) of 17, seven (36%) of 19, and 0 of 20 wolves for these diseases, respectively. Pups died or disappeared in three of the eight packs studied. In these three packs, adult pack members had CPV titers > or = 1,600 or CD titers > or = 1,250. In packs that successfully raised pups, CPV and CD titers were low. We propose that CPV or CD may have caused some pup mortalities.

Physicians are familiar with the "slapped cheek" rash seen in childhood cases of erythema infectiosum. Less well known is that infection with its pathogen, parvovirus B19, often becomes manifest in adults as acute viral arthropathy. In evaluation of suspected cases, a complete blood cell count and blood chemistry profile are useful additions to thorough history taking and physical examination. Differential diagnosis includes Lyme disease, other viral infections, acute rheumatoid arthritis, systemic lupus erythematosus, and psoriatic arthritis. Treatment is symptomatic with nonsteroidal anti-inflammatory drugs.

Canine parvovirus infected wild canids more than a decade ago, but no population effect has been documented. In wild Minnesota wolves (Canis lupus) over a 12-yr period, the annual percent population increase and proportion of pups each were inversely related to the percentage of wolves serologically positive to the disease. Although these effects did not seem to retard this large extant population, similar relationships in more isolated wolf populations might hinder recovery of this endangered and threatened species.

Parvovirus B19 can cause a wide range of cutaneous or extracutaneous diseases. There are three types of exanthemas, erythematous maculopapulous or vesicopapulous exanthema including erythema infectiosum, the less common maculoerythematous exanthemas and purpural exanthemas including vascular, thrombocytopenic or non-vascular or non-thrombopenic forms such as le socks and gloves syndrome. Reports of other manifestations have been more sporadic: generalized livedo, polymorphous rash, lupus-like rash and Kawasaki syndromes. The presence of unusual presentations and the risk of fetomaternal transmission are two reasons for better understanding this virus.

We reviewed the literature on relationships between human parvovirus B19 infection and rheumatic diseases. Parvovirus B19 causes erythema infectiosum in childhood, transient anemia in immunocompetent individuals, and potentially severe infections in fetuses; laboratory evidence that the virus is directly responsible for these disorders has been obtained. Acute arthropathy meeting American College of Rheumatology criteria for rheumatoid arthritis and disorders meeting some of the classification criteria for systemic lupus erythematosus are the most striking rheumatic manifestations of parvovirus B19 infection. Purpuric lesions have also been reported. Parvovirus B19 infection may be capable of inducing a number of manifestations that have not yet been described in the literature. Although the relationship between human parvovirus B19 infection and rheumatic diseases has been the focus of many studies, compelling evidence that the virus is directly involved in the pathogenesis of rheumatic diseases has not yet been obtained.

From October 1989 to June 1993, we captured and sampled 110 coyotes (Canis latrans) for various diseases in Yellowstone National Park, Wyoming (USA). Prevalence of antibodies against canine parvovirus (CPV) was 100% for adults (> 24 months old), 100% for yearlings (12 to 24 months old), and 100% for old pups (4 to 12 months old); 0% of the young pups (< 3 months old) had antibodies against CPV. Presence of antibodies against canine distemper virus (CDV) was associated with the age of the coyote, with 88%, 54%, 23%, and 0% prevalence among adults, yearlings, old pups, and young pups, respectively. Prevalence of CDV antibodies declined over time from 100% in 1989 to 33% in 1992. The prevalence of canine infectious hepatitis (ICH) virus antibodies was 97%, 82%, 54%, and 33%, for adults, yearlings, old pups, and young pups, respectively. The percentage of coyotes with ICH virus antibodies also declined over time from a high of 100% in 1989 to 31% in 1992, and 42% in 1993. Prevalence of antibodies against Yersinia pestis was 86%, 33%, 80%, and 7%, for adults, yearlings, old pups, and young pups, respectively, and changed over time from 57% in 1991 to 0% in 1993. The prevalence of antibodies against Francisella tularensis was 21%, 17%, 10%, and 20%, for adults, yearlings, old pups, and young pups, respectively. No coyotes had serologic evidence of exposure to brucellosis, either Brucella abortus or Brucella canis. No coyotes were seropositive to Leptospira interrogans (serovars canicola, hardjo, and icterohemorrhagiae). Prevalence of antibodies against L. interrogans serovar pomona was 7%, 0%, 0%, and 9%, for adults, yearlings, old pups, and young pups, respectively. Antibodies against L. interrogans serovar grippotyphosa were present in 17% of adults and 0% of yearlings, old pups, and young pups. Many infectious canine pathogens (CPV, CDV, ICH virus) are prevalent in coyotes in Yellowstone National Park, with CPV influencing coyote pup survival during the first 3 months of life; eight of 21 transmitted pups died of CPV infection in 1992. The potential impact of these canine pathogens on wolves (C. lupus) reintroduced to Yellowstone National Park remains to be documented.

Over a period of 29 months, from January 1991 to December 1994, all cases of acute polyarthritis seen at the Rheumatology Service in our Institution were studied to determine the seroprevalence of parvovirus B19 (B19) infection. The variables studied included: age and sex of patients, presence of fever and rash, Anti-B19 IgM and IgE serological determinations (ELISA, Mardix Lab.), follow-up time and final diagnosis. The study included 36 patients (22 women and 14 men, mean age 34 +/- 19 years). Thirteen and seven patients had fever and cutaneous rash, respectively. Anti-B19 IgM serology was positive in 4 patients; in 2 of them IgG seroconversion was confirmed. The mean follow-up time was 14 +/- 9 months. Final diagnoses included undifferentiated polyarthritis, rheumatoid arthritis, B19 polyarthritis, systemic lupus erythematosus, and miscellaneous in 19, 7, 4, 2, and 4 patients, respectively. Seroprevalence of B19 infection in acute polyarthritis in our area was 11%, approximately.
