Clinical case of acute hepatitis caused by parvovirus B 19

Parvovirus infection is one of the most widespread infectious diseases in the world. Parvovirus В19 can cause a wide range of clinical manifestations with possible long-term viral persistence. Infectious erythema, arthropathy, fetal infection, and blood cell aplasia are the most common manifestations of parvovirus infection. A case of diagnosis and treatment of a rare variant of parvovirus B19 infection that occurred as acute hepatitis is presented.

Parvovirus Infection in a Child Presenting with Erythema Multiforme and Vasculitis after a Yellow Jacket Bee Sting

Parvovirus B19 has a wide spectrum of clinical manifestations. Erythema multiforme and vasculitis are rarely reported with parvovirus B19 infections. Reactions to insect stings can range from local swelling to life-threatening systemic reactions. There have been rare reports of unusual reactions, such as vasculitis, occurring in a temporal relationship with insect stings. We report an 8-year-old patient having Parvovirus B-19-related erythema multiforme and vasculitis after a yellow jacket bee sting.

Diagnosis of Viral Myocarditis in Children with Clinical Suspicion of Myocarditis by Multiplex Real-time PCR in Birjand Vali-Asr Hospital, East of Iran

Background Viral myocarditis (VMC) is one of the common heart diseases to endanger human health in different age groups, especially children. The aim of this study was diagnosis of viral myocarditis in children with clinical suspicion of myocarditis by multiplex Real-time PCR in Birjand Vali-Asr hospital.Methods This cross-sectional research conducted on 19 patients with clinical suspicion of myocarditis who had evidence of microbial infections in recent weeks. Routine electrocardiogram and dynamic ECG examinations, auxiliary laboratory testing and echocardiographic evaluation were performed. Multiplex Real-time PCR by Neuro kit was used for detection of viral agents in blood or pericardial fluid samples.Results The results indicated that 4 out of 19 (21.05%) patients with myocarditis were found to be virus positive. The spectrum of viral agents was included HHV-6/7, Parvovirus B-19, EBV, VZV and Adenoviruses. A co-infection of HHV-6/7 and Parvovirus B-19 was found in the one patient. ECG findings such as sinus tachycardia with ST-T changes, premature ventricular contraction and complete heart block were found in VMC patients. The predominant echocardiographic features in the patients with VMC were a low ejection fraction, mitral regurgitation and severe pericardial effusion with hypotension. AST and LDH abnormal increase were found in the some patient.Conclusions Our findings highlight the importance of identification of VMC in children with clinical suspicion of myocarditis. The present study emphasizes the importance of PCR-based assays for detection of viral agents in myocarditis patients with symptoms of virus infection.
