“…For example, Monteleone et al ( 2022) reported a decrease of means of the lactulose/mannitol (LA/MA) test and Kleppe et al (2004) reported a decreased in zonulin serum concentration in favour of a decrease in IP. On the other hand, Grigioni et al (2022) reported an increased urinary LA/MA ratio in patients with AN when compared to controls, that may indicate an increased IP.…”

“…Hence, these two shortcomings may explain why IgG autoantibodies against α-MSH have been found in AN patients and normal weight controls [ 24 , 81 83 ], the high inter-individual variability that has been observed [ 79 , 83 ], and the inconsistent data regarding the very existence of a greater concentration of this bacteria in AN [ 24 , 79 , 83 ]. Moreover, differences in molecular affinity properties are inconclusive, as sometimes the dissociation rate may be higher [ 84 ], or lower [ 83 ] in AN than in a normal weight control group.…”

“…Finally, further research is required to ascertain if these molecules are transported through the blood–brain barrier, and to determine the mechanisms enabling them to cross the intestinal barrier, as the evidence regarding intestinal hyperpermeability in AN patients is inconsistent [ 83 , 86 , 87 ]. Likewise, the recent integration of the role of CCK-4 in this model [ 27 ] is also controversial.…”

“…A partir disso, a modulação da microbiota intestinal pode ser útil para alterar a história natural dos transtornos alimentares(NAVARRO-TAPIA et al, 2021).As bactérias intestinais são necessárias para o funcionamento normal do cérebro, de maneira que traços comportamentais são transmissíveis por meio destas(LAM et al, 2017). Ao referir-se a AN, fatores como o aumento da permeabilidade intestinal, presença de inflamação de baixo grau, autoanticorpos e neogênese relacionam-se com alguns sintomas depressivos, ansiosos e do próprio transtorno alimentar (SEITZ; TRINH; HERPERTZ-DAHLMANN, 2018), portanto, fatores que contribuem para manutenção do quadro.Em um estudo de caso-controle prospectivo desenvolvido porGrigioni et al, (2022) objetivou comparar a permeabilidade intestinal, peptídeos reguladores do apetite e suas imunoglobulinas reativas na AN. Foram incluídos indivíduos do sexo feminino gravemente desnutridas com AN, apresentavam IMC médio de 14,9 kg/m², nesse cenário, quando comparados a um controle com mulheres saudáveis estas apresentavam uma relação lactulose/manitol urinária aumentada, a partir disso, observou-se uma maior permeabilidade intestinal nesse grupo.Conforme descrito, o aumento da permeabilidade intestinal está associado a inflamação de baixo grau(DALTON et al, 2018).…”
