Resumo: | Obesity is a worldwide health problem and the increase in its incidence, risks and consequences are a matter of growing concern. Obesity is characterized by the accumulation of fat in the body. Many studies are currently investigating obesity and associated comorbidities in an attempt to clarify the mechanisms involved. Fat tissue is a dynamic organ that secretes several factors, including adipokines. Adipokines are bioactive peptides secreted by fat cells, which are important for energy regulation and inflammatory and immune responses. Leptin, adiponectin and resistin are the most studied adipokines. The aim of this review was to gather information about these adipokines (leptin, adiponectin and resistin) and their relationship with the immune response in obese individuals, as well as the susceptibility of these patients to infections. The results of the literature review permit some observations. The circulating levels of these adipokines are directly involved in the degree of obesity of the patient. High or low circulating concentrations of these adipokines may have beneficial or negative effects on immune competence, with obese patients being more susceptible to infection and inflammation than eutrophic individuals.Key words: Obesity; Adipokines; Leptin; Adiponectin; Resistin; Immune system. |

Essa enfermidade é ca-racterizada pelo acúmulo de tecido adiposo no organismo. Atualmente, muitos estudos estão direcionados à obesidade e as comorbidades associadas a esta patologia, visando esclarecer os mecanismos envolvidos. O tecido adiposo é um órgão dinâmico que secreta vários fatores, dentre eles as adipocinas. As adipocinas são peptídeos bioativos secretados pelos adipócitos e são importantes na regulação energética, resposta inflamatória e imunológica. Entre as adipocinas mais estudadas estão a leptina, adiponectina e resitina. O objetivo desta revisão foi reunir informações sobre as adipocinas estudadas (leptina, adiponectina e resistina) e suas relações com a resposta imunológica em indivíduos obesos, e a susceptibilidade desses pacientes à infecções. A partir dos dados encontrados na literatura algumas constatações podem ser realizadas. Os níveis circulantes dessas adipocinas estão diretamente associados ao grau de obesidade apresentado pelo indivíduo. Elevadas ou baixas concentrações circulantes das adipocinas estudadas podem acarretar benefícios ou prejuízos à competência imunológica, fazendo com que pessoas obesas sejam mais susceptíveis a infecções e infla-mações que indivíduos eutróficos.Universidade Federal de Santa Catarina.
