Detection of Parvovirus B19 Infection in Thalasemic Patients in Isfahan Province, Iran.

BACKGROUND

Parvovirus B19, a member of the Erythrovirus genus of Parvoviridae family, causes various clinical illnesses including infectious erythema, arthropathy, hydrops fetalis or congenital anemia, and transient aplastic crises. The B19 virus can be transmitted through respiratory secretions, blood products, and blood transfusion.

OBJECTIVES

The aim of this study was to detect the B19 virus in thalassemia patients in Isfahan, Iran.

PATIENTS AND

METHODS

The prevalence of parvovirus B19 infection was compared between thalassemia major patients and healthy subjects. Plasma samples were collected from 30 thalassemia patients from Isfahan, Iran. Thirty patients without any blood complications were considered as the control group. After DNA extraction from the plasma samples, polymerase chain reaction was performed for parvovirus B19 detection.

RESULTS

The parvovirus B19-specific nucleotide sequence was detected in 6 patients (20%). None of the samples obtained from the 30 control subjects tested positive for B19.

CONCLUSIONS

In this study B19-Parvovirus infection were detected in patients with hematologic disorders in comparison with control subjects. Screening of patients with a high risk of parvovirus B19 infection can considerably reduce the incidence and prevalence of B19 infection.
