Twenty-seven infants with cytomegalovirus hepatitis were followed up for 15-40 months after onset of the illness. They had recovered from the hepatitis, but microcephaly was present in 2 (7.4%), sensorineural hearing loss in 5 (18.5%), quadriplegia, mental retardation, ventricular septal defect and tooth defects in 1 (3.7%) each. The patients with congenital infection had more severe and complex defects, some with perinatal infection had mild defects, those with postnatally acquired infection had no sequelae. The mean MDI and frequency of expressive language delay in the former group differed significantly from those of the other 2. Five patients still excreted cytomegalovirus in the urine at follow-up.

To determine the seroprevalence of maternal and neonatal toxoplasmosis and cytomegalovirus (CMV) antibodies and hepatitis-B (HB) antigenaemia in a rural Egyptian area, a prospective serological study was done on a randomly selected sample of pregnant women (n = 150) and their newborn infants (n = 150). Sera were collected from the mothers during the first antenatal visit, and at the time of delivery and cord blood specimens (paired samples) taken from their infants to be tested for toxoplasma-IgG and IgM antibodies, CMV-IgG and IgM antibodies surface antigen (HBsAg) and HBe antigen (HBeAg). Maternal infection was indicated in cases where specific IgM antibody was present or where an initial maternal specimen gave negative result for IgG antibody, but the second blood specimen gave positive result. Specific IgM antibody in a cord blood specimen indicated fetal infection. Out of the 150 pregnant women, 64 (43 percent) were toxoplasma immune at their first antenatal visit and their newborns were toxoplasma IgG positive. Toxoplasma specific IgM antibody was detected in only three mothers at the time of deliver. The rate of maternal infection in susceptible pregnancies was 4 percent and the maternal-fetal transmission rate was estimated to be 33 percent, as only one newborn infant had toxoplasma-IgM antibody at birth. This denoted a prevalence of congenital toxoplasma infection = < 1.0 percent to non-immune mothers. There were no clinical features of congenital infection in the infant with toxoplasma-IgM antibody, but he will require long-term follow-up. All the mothers infected during pregnancy had known risk factors for toxoplasma infection. One-hundred-and-forty-three (96 percent) of the pregnant women were CMV-IgG seropositive at their first antenatal visit. At the time of delivery 143 (96 percent) of the mothers and their newborn infants were CMV-IgG seropositive. None of the mothers or their infants was CMV-IgM seropositive. HBsAg was detected in 8 per cent of pregnant mothers (n = 12) and in two (17 percent) of their newborn infants. None of the mothers was HBeAg positive. In conclusion, the prevalence of toxoplasma infection during pregnancy and its transplacental transmission rate in a rural Egyptian area are high compared to other countries. A toxoplasmosis antenatal screening and public education programmes for pregnant mothers is justifiable in rural Egypt. However, it appears that an antenatal screening programme for CMV is, at present, not warranted.

We present two siblings with congenital and progressive encephalopathy associated with systemic lupus erythematosus. The two brothers presented soon after birth with an encephalopathy associated with intracranial calcification (=2), intrauterine growth retardation (= 2), hepatitis (= 1) and thrombocytopenia (= 1), mimicking a congenital virus infection. Within the first year of life both children developed hypocomplementaemia and systemic lupus erythematosus (SLE), the main features of which were a discoid lupus-like rash on the hands and feet and the progressive production of high levels of autoantibodies. Both children were severely handicapped and died in early childhood from streptococcal infections. There are many causes of congenital encephalopathy with intracranial calcification. The early development of systemic lupus in these children suggested that their cerebral disease formed part of an autoimmune process. Complement levels and autoantibody profiles should be considered part of the investigation of a child with congenital infection-like syndrome, particularly when there are progressive dermatological complications.

We report a term male infant presenting on postnatal day 1 with fulminant hepatic failure. Described congenital infection, metabolic disorders, and cardiovascular etiologies of acute neonatal liver failure were assessed and eliminated. A liver biopsy on postnatal day 10 showed neonatal giant cell hepatitis (NGCH) with an unusual degree of fibrosis for this early postnatal age. NGCH is a clinical diagnosis of cholestatic disorders of unknown etiology in the newborn, and, to our knowledge, has not been previously associated with immediate neonatal hepatic failure. The giant cell transformation is a common response to a variety of insults and only rarely occurs beyond the neonatal period. Most cases present with cholestatic jaundice and varying degrees of coagulopathy, and, many, as in this case, show progressive resolution.

The genetic variability of 74 human cytomegalovirus (HCMV) clinical isolates from 60 Japanese infants and children during 1983-2003 was investigated, and the relevance to their clinical course was studied. The patients consisted of 10 asymptomatic congenitally infected babies, 45 infected perinatally or postnatally resulting in HCMV mononucleosis/hepatitis and 5 immunocompromised hosts. The hypervariable region of the HCMV genome, that is the a sequence and UL144 region was analyzed using the polymerase chain reaction (PCR) and unrooted phylogenetic trees. HCMV glycoprotein B (gB) polymorphism was also studied. Unrooted phylogenetic trees of a sequence and UL144 allowed the isolates to be grouped to 5 and 3 clades, respectively. Three gB genotypes were also determined. However, there was no correlation between specific genotypes of these three genes and clinical forms, except for congenital infection which fell into one of three clades of the UL144 gene. In addition, the variability of the three genes had no correlation with each other. This implies that study of a single gene is insufficient for investigating the molecular epidemiology of HCMV. This study provides basic data on the genetic variability of HCMV in an Asian population and should help to determine the strains for vaccine candidates.

Cytomegalovirus primary infection is considered dangerous for some kinds of patients: immunocompromised (HIV-infected and transplanted patients), newborns with congenital infection, and immunocompetent patients in critical condition. CMV infection is usually asymptomatic or only mildly symptomatic in immunocompetent hosts. We collected all cases of acute CMV infection that came to our attention during the period November 2009 - May 2011 to analyze their clinical features. Immunoenzymatic methods (ELISA) were used for the detection of specific IgM and IgG antibodies in every case. We observed 73 cases of acute CMV infection. The male-female ratio was 1.5/1. The average age was 36.4. All the patients had fever, 16 (22%) pharyngitis, only 9 (12.3%) lymphadenopathy. The most common complications were hepatitis, encephalitis, pericarditis and pneumonia. Unknown genetic factors may greatly influence the clinical expression of the illness.

Human cytomegalovirus is a common virus that establishes latency and persistence after a primary infection in 50-90% of populations worldwide. In otherwise healthy persons, the infection is generally mild or asymptomatic, although it may cause mononucleosis, prolonged episodes of fever, and hepatitis. However, in AIDS patients and transplant recipients who are immunosuppressed, severe, life-threatening infections may develop. CMV is also the most common congenital infection and may cause birth defects and deafness. Emerging evidence shows a high prevalence of this virus in patients with chronic inflammatory diseases or tumours of different origin, such as breast, colon, and prostate cancer, neuroblastoma, medulloblastoma, and glioblastoma. Several drugs are available to treat CMV infections. This review will highlight the possibility of using anti-CMV therapy to improve outcome not only in patients with acute CMV infections but also in patients with inflammatory diseases and cancer.

Cytomegalovirus (CMV) is currently the most common cause of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Perinatal CMV infection rarely causes clinical manifestations in normal individuals and usually follows a benign course in immunocompetent infants. However, ~15-25% of infected preterm infants may develop pneumonia, hepatitis or sepsis-like illness, bradycardia, hepatosplenomegaly, distended bowel, anemia, or thrombocytopenia. Bronchiolitis obliterans (BO) is a rare, fibrosing form of chronic obstructive lung disease that follows severe insults to the lower respiratory tract and results in narrowing and/or complete obliteration of the small airways. In non-transplant children, the most common form of BO is a severe lower respiratory tract infection, especially of adenovirus. We experienced a case of a 37-day-old male who was diagnosed as BO on chest computed tomography (CT) after CMV pneumonia. To our best knowledge, this is the first case of BO caused by CMV pneumonia in a healthy infant.

The eye manifestations of intrauterine infections are multiple, but chorioretinal scars and/or active chorioretinitis are the most frequently reported. When associated with other systemic manifestations of the infection, the diagnosis becomes more obvious, but when eye involvement is the only abnormality, etiology often remains uncertain. We are presenting the case of an 8-year-old female patient whose fundus lesions revealed an unusual choroidoretinopathy, associated with cataract in one eye. Her general examination and her medical history were unremarkable. Blood test for multiple pathogenic agents (HIV, hepatitis Band C, Toxoplasma, Toxocara, Borrelia, CMV, Epstein-Barr virus) were negative. Complete blood count, ESR, fibrinogen and CRP are all within normal limits. Plasma ornithine levels were in normal range (ruling out a diagnosis of gyrate atrophy). The chorioretinal lesions discovered in this 8 years old child may be caused by an acquired or a congenital infection. As in most similar cases, the clinical aspect, the medical history and the blood work did not help too much in establishing the moment of the infection or the causative agent. A complete clinical, structural and functional base-line evaluation is however mandatory when facing such a case. Periodic follow-up is recommended in order to assess the evolution of the disease.

Congenital infection with cytomegalovirus (CMV) is the main cause of sensorineural hearing loss and psychomotor impairment which can develop at birth or later in infant's life. Because of a lack of nation-wide serological screening for pregnant women and accepted antiviral therapy during pregnancy in a high seroprevalence rate population of Poland, we introduced the regional screening programme for CMV infection in neonates from the Poznan Province to diminish a risk of the symptomatic disease. The aims of the study were: (i) to determine the prevalence of specific anti-CMV antibodies in populations of pregnant women and newborns from the Poznan area, (ii) to increase the early postnatal detection of congenital CMV infections, and (iii) to evaluate a risk of perinatal or early postnatal infections with CMV in newborns or infants born to seropositive mothers. Serological testing was performed in 4.192 live born neonates, using dried blood filter-paper specimens. The seropositivity rate in the studied population of neonates and pregnant women was 78.6%. The incidence of perinatal and early postnatal CMV infections was evaluated to be 3.1% or 1 per 25 neonates born to seropositive mothers. Congenital CMV infections confirmed by a presence of specific IgM antibodies were diagnosed in 5 newborns, which represent 1 case per 838 successive deliveries. In a clinical pattern of cytomegalovirus disease respiratory disorders and low birth weight were most frequently observed, and neurological signs, hepatitis, haemorrhagies or jaundice were sporadically diagnosed. Implementation of mass immunodiagnostic screening for congenital CMV infection, combined with other obligatory neonatal tests for metabolic errors, congenital malformations and endocrine disorders seems to be a valuable third line prophylactic strategy to prevent a late development of clinically overt cytomegalovirus disease.
