Characterization of lymphocyte profiles in children with syndromic obesity

BACKGROUND

Little is known about blood lymphocyte subpopulations in children with common (CO) or syndromic (SO) obesity. We aimed to describe the blood lymphocyte profiles of obese children and to search for associations with clinical phenotypes.

METHODS

Main blood lymphocyte subpopulations were analyzed in 159 children with CO and 34 with SO in a retrospective cohort. Phenotypes included obesity history, body mass index (BMI) Z score, percentage fat mass, and inflammatory parameters. Correlations were performed between phenotypes and circulating lymphocyte profiles.

RESULTS

Children with SO had a higher BMI Z score (5.5 ± 1.7 SD) than children with CO (4.7 ± 0.9 SD; p = 0.01). Significant differences were found for lymphocyte counts, including a higher percentage of CD19⁺ B cells (SO = 20.1 ± 6.7 vs. CO = 17.1 ± 6.1%, p = 0.03), despite lower absolute numbers (SO = 0.57 ± 0.20 vs. CO = 0.63 ± 1.9 g/L, p < 0.01). However, no difference in the lymphocyte profile was found between children with SO and those with the most severe CO (BMI Z score ≥ 4.7 SD).

CONCLUSION

Children with SO have altered blood lymphocyte profiles with increased prevalence of CD19⁺ B cells, which is closely linked to the degree of obesity severity and inflammatory markers.

Medical check-up of newly arrived unaccompanied minors: A dedicated pediatric consultation service in a hospital

BACKGROUND AND AIMS

Healthcare for the increasing number of migrants in Europe, and particularly of unaccompanied minors (UMs) seeking asylum, has become a major challenge. We aimed to describe the health issues of UMs managed in a dedicated pediatric consultation service in a care center in Paris.

METHODS

All UMs attending a dedicated migrant medical consultation service in Robert Debré Hospital, Paris, France, were included in a single-center retrospective observational study from September 1, 2017, to September 30, 2018.

RESULTS

Out of the 107 UMs who were included, 87% had a health problem (n=93) and 52% had an infectious disease (n=56). The main infectious diagnoses were schistosomiasis (22%), latent tuberculosis (22%), intestinal parasitosis (16%), and chronic hepatitis B (8%). Posttraumatic stress disorder (PTSD) and overweight were common (35% and 20%, respectively). The median age was 15 years old (IQR, 14-16), the male/female ratio was 95/12. Most of the children were from sub-Saharan Africa (n=67), 46% had crossed Libya (n=49) and, when compared to the other migration routes, faced an increasing risk of violence (69%, p=0.04), imprisonment (53%, p=0.03), and forced labor (48%, p=0.02). The median duration of the trip before reaching France was 6 months (IQR, 2-13), the median time to consultation was 2 months (0-5) and was not associated with an increased risk of health problems. A total of 43 UMs were lost to follow-up.

CONCLUSION

Health problems, particularly infectious diseases and PTSD, are common among UMs and should prompt an early medical consultation with psychiatric evaluation. Follow-up is problematic and could be improved by an on-line health book.
