BREYER DE FREITAS, Bruna et al. Nutritional and metabolic assessment in overweight patients with and without hyperprolactinemia caused by prolactinoma. Nutr. Hosp. [online]. 2015, vol.32, n.5, pp.2030-2037. ISSN 1699-5198.

Introduction: prolactinomas are pituitary adenomas that express and secrete prolactin. These patients are overweight and the mechanisms are being studied. Goals: assess nutritional and metabolic status of overweight patients with and without hyperprolactinemia caused by prolactinoma and compare them. Materials and methods: cross-sectional study, patients with body mass index (BMI) ≥ 25 kg/m2 with and without prolactinoma: 1) 20 normoprolactinemic (NPrl) with prolactinoma; 2) 23 hyperprolactinemic (HPrl) with prolactinoma; 3) 28 controls without prolactinoma or alterations in prolactin levels. Evaluated through anthropometric, dietetics, and biochemical assessment. Results: of the 71 patients evaluated, most were obese women with macroprolactinomas. All three groups had diets with low caloric and monounsaturated fatty acid (MUFA) intake, the NPrl group had low carbohydrate (CHO) intake and high lipid (LIP) and saturated fatty acid (SFA) intake, and the NPrl and HPrl groups had appropriate intake of polyunsaturated fatty acids (PUFA). The HPrl group had elevated total cholesterol. HDL cholesterol was below the recommended threshold for most patients. No statistically significant differences were found in anthropometric and biochemical variables among the groups. Conclusions: most patients with prolactinomas and controls are obese and metabolically similar regardless of prolactin levels. All groups presented low caloric and MUFA intake. Protein, LIP, SFA, and cholesterol were significantly different among the groups, the NPrl group ingested less amount of protein and greater of fat. Snacking between meals and changes of food consumption on weekends was reported by most patients. This is the first study comparing patients with prolactinomas and controls, both with overweight, regarding food consumption and feeding behavior.
