[Parvovirus B19 infection in patients with congenital blood coagulation disorders].

BACKGROUND: The aim of this study is to assess the prevalence of Parvovirus B19 infection in a group of patients affected by congenital coagulation disorders and its association with epidemiological aspects. PATIENTS AND METHODS: We have analyzed a group of 50 patients (median age 28) diagnosed with haemophilia or any other congenital coagulation disorder and 111 healthy non-transfused controls (median age 30) for IgG and IgM antibodies to Parvovirus B19 (Dako A/S, Glostrup, Dinamarca). Other issues analysed were HIV coinfection, the use of virally inactivated or non-inactivated plasma products and clinical symptoms of the infection. RESULTS: 84% of the patients (93.3% of those previously transfused) and 60.3% of the controls subjects showed IgG antibodies against Parvovirus B19. None of them had specific IgM antibodies. Five patients (all of them seronegative) had never been exposed to any plasma derivative and 11 were HIV-positive. The differences found between the prevalence of parvoviral infection in patients and controls are statistically significant, but those differences are only confirmed in younger patients (< 30) when age groups are compared. However, the severity of the haemostatic disorder, the type of plasma products infused or HIV coinfection had no influence on prevalence rates. The infection was clinically asymptomatic in all the cases. CONCLUSIONS: Haemophilic patients of any age are exposed to a higher risk of Parvovirus B19 infection than general population, although this infection had no clinical relevance in our study. The use of virally inactivated factor concentrates or the severity of the haemostatic disorder has no influence on this infectious risk.

[Rheumatic manifestations associated with infection by the hepatitis C virus].

The development in the past few years of laboratory test for hepatitis C virus allow us to associate it with a broad range of autoimmune manifestations such as cryoglobulinemia and Sjögren syndrome. As in other virus' infections, rheumatic manifestations have been described during VHC infection, but there are no large studies enough to know their true frequency and characteristic. The three reported patients in this issue presented and HCV related arthropathy once clinical picture, laboratory test and following, allowed us to exclude other diagnostics. Clinical manifestations ranged from arthralgias and intermittent arthritis to symmetric polyarthritis without any kind of join damage.

[Brain stem encephalitis due to herpes simplex].

Brainstem encephalitis is an unusual infection caused by a variety of agents, among them the herpes simplex (HS) virus. The difficulty of establishing a diagnosis by neurophysiological and radiological examination is greater in this type of encephalitis than in the usual form produced by HS. We describe a fatal case of brainstem encephalitis. Inflammatory and necrotic lesions in the pous and medulla confirmed the clinical diagnosis, while the etiology was determined by immuno-histo-chemical techniques and viral culture of the cerebral parenchyma. Early diagnosis of this form of encephalitis, based on new virological techniques, allows more effective antiviral treatment.

[Type 4 echovirus meningitis in childhood. Epidemiologic and clinical aspects apropos of an epidemiologic outbreak].

In the first half of 1988 we observed 13 cases of lymphocytic meningitis from which echovirus type 4 was isolated in the CSF. We found a higher infection rate in the 6-9 years old group (54%) and in the masculine sex (69%). Almost all of the cases occurred during the springtime. The clinical and CSF characteristics of this epidemic do not differ much from those that have appeared in the literature. Throughout 1988, in our hospital, 46 cases of lymphocytic meningitis took place and in 20 of them an etiologic diagnosis was done. We think that the introduction of enterovirus cultures can help to know the etiology of many of these cases of meningitis since this virus is responsible for a great part of them.
