Prospective study of consecutive patch testing in patients with contact dermatitis using an adapted Latin American baseline series
Conclusions. This study demonstrated a detailed profile of a population with suspected allergic contact dermatitis. Our patch test results, using an adapted Latin American baseline series, represent a significant update of this important diagnostic tool.PMID:35261227 | DOI:10.23822/EurAnnACI.1764-1489.250

Gut microbiota of children with atopic dermatitis: Controlled study in the metropolitan region of S ão Paulo, Brazil.
CONCLUSIONS: This study confirmed that children living in the metropolitan area of São Paulo (Brazil) with AD have a different microbiota pattern with higher prevalence of C. difficile, lower abundance of Lactobacillus and greater abundance of bifidobacteria, regardless of socioeconomic status.

Polymorphisms in the DAD1 and OXA1L genes are associated with asthma and atopy in a South American population
This study aimed to evaluate how polymorphisms in DAD1 and OXA1L are associated with asthma and markers of atopy in individuals from the Salvador cohort of the SCAALA (Social Change Asthma and Allergy in Latin America) program. The DNA of 1220 individuals was genotyped using the Illumina 2.5 Human Omni Bead chip. Logistic regression analyses were performed with PLINK 1.9 software to verify the association between DAD1 and OXA1L polymorphisms and asthma and atopic markers, adjusted for sex, age, helminth infections and ancestry markers, using an additive model. The DAD1 and OXA1L genes were associated with some of the evalu...
