Strongyloidiasis, a neglected helminthiasis, is more prevalent in tropical/subtropical areas. However, sporadic autochthonous cases have been described around the Mediterranean coast. We performed a retrospective descriptive study in a referral Spanish Center for Pediatric Tropical diseases. All patients below 18 years of age diagnosed with probable strongyloidiasis between January 2014 and December 2019, born in Spain and with no history of travel abroad, were included. Epidemiological, clinical, and follow-up data were recorded, as well as all microbiology results. Five children met the inclusion criteria and were included in the study. Three males and two females, with a median age of 6.7 years (IQR: 5.8–9.1). All patients had previous medical conditions and used to spend holidays on the Mediterranean coast of Spain. All but one were mildly symptomatic at diagnosis but only four presented peripheral eosinophilia, which was the main reason for referral. First-line treatment was ivermectin in all but one, who was treated with albendazole. Reinfection was suspected in two during follow-up. At 12 months of follow-up 3/5 (60%) children presented negative serology. Conclusion: Although more prevalent in tropical areas, strongyloidiasis should be included among differential diagnosis in children presenting with eosinophilia. Screening for strongyloidiasis should be considered in all children candidate to immunosuppressive therapy. What is Known: • Strongyloidiasis is more prevalent in tropical/subtropical areas. • Strongyloidiasis can be life-threatening in immunosuppressed patients What is New: • Spanish children can be affected by autochthonous strongyloidiasis. • Screening for strongiloidiasis should be performed in all candidates to immunosuppresive therapies, including children.

Background: Congenital cytomegalovirus infection (CMVc) affects 0.7%-6% of recent births. Among its clinical manifestations are low weight and length at birth., Objective: Describe the growth patterns of children with CMVc in their early years., Methods: Observational, multicenter study of patients with CMVc. Anthropometric data were collected during the first 2 years of life and compared with World Health Organization standards., Results: Anthropometric characteristics of 383 children with CMVc were studied, of which 198 (51%) were symptomatic at birth. At birth, 9% were small for gestational age (SGA) in terms of their weight and length and 17% had microcephaly. At 24 ± 3 months, 10% had a weight and length ≤2 SD, and 13% a head circumference ≤2 SD. Of those who were SGA at birth, at 24 ± 3 months >20% remained at ≤2 SD of their weight and length. Conversely, 75% of children with low weight or length at 24 ± 3 had not been SGA at birth. 20% of infants with microcephaly at birth remained with microcephaly, and 10% of those without microcephaly developed it at 24 ± 3 months. The average growth rate in length and weight was normal. Patients who were symptomatic at birth, premature and with motor and neurocognitive impairment had a significantly higher risk of low weight and length at 24 ± 3 months., Conclusion: Around 10% of children with CMVc are at ≤2 SD in weight, length and head circumference at 24 ± 3 months. The lack of adequate growth is associated with symptoms at birth, prematurity and motor and neurocognitive impairment. Growth impairment could be incorporated into the symptomatic spectrum of CMVc.
