The Frequency of Cytomegalovirus and Toxoplasma Among Microcephalic and Hydrocephalic Neonates Admitted to Pediatric Hospital in Bandar Abbas

 Congenital infection is a primary cause of malformations during infancy including hydrocephaly and microcephaly. In addition, cytomegalovirus and toxoplasma are the two prevalent causes of congenital infections. The present research aimed to investigate the prevalence of cytomegalovirus and toxoplasma infections among neonates afflicted with microcephaly and hydrocephaly in a pediatric hospital in 2018.

The present descriptive, cross-sectional research was conducted on all neonates diagnosed with microcephaly and hydrocephaly hospitalized in the pediatric hospital of Bandar Abbas in 2018. Blood samples were taken from the neonates to be analyzed for cytomegalovirus and toxoplasma serology, followed by statistically analyzing the information describing 11 subjects including 5 hydrocephaly and 6 microcephaly cases.

The mean gestational age was estimated at 35.8 ± 4.08 and 37.16 ± 1.32 weeks in hydrocephaly and microcephaly groups, respectively (P = 0.507). In both groups, the female population was larger than the males. In addition, blood relations among parents were stronger in the microcephaly group (40%) compared to the microcephaly group (83.3%). Moreover, the anomaly was found to be more in the microcephaly group. This rate was 60% and 16.7% in the hydrocephaly and microcephaly groups, respectively. The serology of cytomegalovirus and toxoplasma in neither groups showed to be positive. One hundred percent of patients with an anomaly were term although 50% of those without any anomaly belonged to the term group. It appears that the presence of an anomaly was positively correlated with term birth. One hundred percent of patients with an anomaly were found to have parents who were close relatives. However, 50% of patients with no anomaly showed to have parents closely related in the family. Finally, heart problems were found to prevail in the group diagnosed with an anomaly.

In the present research, the prevalence of cytomegalovirus and toxoplasma infections was reported to be zero in neonates who were afflicted with microcephaly and hydrocephaly.
