Abstract

Elevated levels of the proinflammatory cytokine Interleukin-6 (IL-6) are among the most consistent findings in patients with major depressive disorder (MDD). Additionally, some evidence suggests that elevated cytokine levels in patients with major depression are responsible for the development of metabolic syndrome in patients suffering from MDD. Therefore, the aim of the study was to examine the concentrations of IL-6 in specific subtypes of MDD and to investigate their relationship to metabolic factors. Twenty-four patients with typical (24) and atypical (eight) major depression according to DSM-IV criteria were studied and compared to 24 normal controls. Blood samples were collected during a stepwise glucose-clamp procedure, and IL-6 concentrations were measured by high sensitivity ELISA. IL-6 levels were elevated in patients suffering from atypical depression but not in patients with typical depression, compared to normal controls. IL-6 correlated significantly with HbA1c, insulin, waist girth, BMI, number of alcoholic drinks per week and C-reactive protein. Our data indicate that high concentrations of IL-6 during the glucose clamp may be limited to the atypical subgroup of patients with MDD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
