Alterations in certain inflammatory markers have been found in individuals with anorexia nervosa (AN). However, their relation to clinical characteristics has not been extensively explored, nor is it clear whether they are trait or state features of the disorder. This cross-sectional study measured serum concentrations of 36 inflammatory markers in people with acute AN (n = 56), recovered AN (rec-AN; n = 24) and healthy controls (HC; n = 51). The relationship between body mass index (BMI), eating disorder psychopathology, depression symptoms and inflammatory markers was assessed. Statistical models controlled for variables known to influence cytokine concentrations (i.e., age, ethnicity, smoking status and medication usage). Overall, most inflammatory markers including pro-inflammatory cytokines were unchanged in AN and rec-AN. However, in AN and rec-AN, concentrations of macrophage inflammatory protein (MIP)-1β were lower than HCs. Interleukin (IL)-7 and IL-12/IL-23p40 were reduced in AN, and concentrations of macrophage-derived chemokine, MIP-1α and tumor necrosis factor-α were reduced in rec-AN compared to HC. In conclusion, a reduction in MIP-1β may be a trait marker of the illness, whereas reductions in IL-7 and IL-12/IL-23p40 may be state markers. The absence of increased pro-inflammatory cytokines in AN is contradictory to the wider literature, although the inclusion of covariates may explain our differing findings.

AbstractBackgroundResting state functional magnetic resonance imaging studies have identified functional connectivity patterns associated with acute undernutrition in anorexia nervosa (AN), but few have investigated recovered patients. Thus, a trait connectivity profile characteristic of the disorder remains elusive. Using state-of-the-art graph–theoretic methods in acute AN, the authors previously found abnormal global brain network architecture, possibly driven by local network alterations. To disentangle trait from starvation effects, the present study examines network organization in recovered patients.MethodsGraph–theoretic metrics were used to assess resting-state network properties in a large sample of female patients recovered from AN (recAN, n = 55) compared with pairwise age-matched healthy controls (HC, n = 55).ResultsIndicative of an altered global network structure, recAN showed increased assortativity and reduced global clustering as well as small-worldness compared with HC, while no group differences at an intermediate or local network level were evident. However, using support-vector classifier on local metrics, recAN and HC could be separated with an accuracy of 70.4%.ConclusionsThis pattern of results suggests that long-term recovered patients have an aberrant global brain network configuration, similar to acutely underweight patients. While the finding of increased assortativity may represent a trait marker of AN, the remaining findings could be seen as a scar following prolonged undernutrition.

Fragestellung: Erwachsene mit Anorexia nervosa (AN) zeigen vor und nach Gewichtsrehabilitation Beeinträchtigungen kognitiver Funktionen. Im Bereich der kindlichen und früh-adoleszenten AN besteht ein großer Bedarf an strukturierten Untersuchungen der kognitiven Funktionen. Bisherige Studien weisen methodische Inkonsistenzen bezüglich der Testauswahl und der Operationalisierung kognitiver Funktionen auf, die die Interpretierbarkeit und Vergleichbarkeit der Befunde deutlich einschränken. Um diese Inkonsistenzen zu verringern, wurde eine neuropsychologische Testbatterie, das sogenannte „Ravello Profil“ entwickelt, das bisher jedoch nicht für den deutschen Sprachraum zur Verfügung steht. Die vorliegende Arbeit stellt daher eine für den deutschen Sprachraum adaptierte Version des Ravello Profils vor und überprüft dessen Anwendbarkeit im Kindes- und Jugendalter. Methodik: Das Ravello Profil wurde für den deutschen Sprachraum adaptiert. Anhand von drei Fallbeispielen wurde die Durchführbarkeit des Ravello Profils bei Kindern und Jugendlichen mit AN überprüft. Ergebnisse und Schlussfolgerungen: Die Fallbeispiele verdeutlichen die Anwendbarkeit des adaptierten Ravello Profils bei Kindern und Jugendlichen mit AN. Das Ravello Profil ermöglicht somit auch im deutschen Sprachraum methodisch konsistente Untersuchungen kognitiver Funktionen bei Kindern, Jugendlichen und Erwachsenen mit AN. Mithilfe des Ravello Profils kann die Rolle kognitiver Funktionen bei der Entstehung einer AN über eine umfassende Altersspanne systematisch untersucht werden.

Objective: This study examines retrospective correlates of nonshared family environment prior to onset of disease, by means of multiple familial informants, among anorexia and bulimia nervosa patients. Methods: A total of 332 participants was included (anorexia nervosa, restrictive type (AN-R): n = 41 plus families); bulimic patients (anorexia nervosa, binge-purging type; bulimia nervosa: n = 59 plus families). The EATAET Lifetime Diagnostic Interview was used to establish the diagnosis; the Subjective Family Image Test was used to derive emotional connectedness (EC) and individual autonomy (IA). Results: Bulimic and AN-R patients perceived significantly lower EC prior to onset of disease compared to their healthy sisters. Bulimic patients perceived significantly lower EC prior to onset of disease compared to AN-R patients and compared to their mothers and fathers. A low family sum – sister pairs sum comparison – of EC had a significant influence on the risk of developing bulimia nervosa. Contrary to expectations, AN-R patients did not perceive significantly lower levels of IA compared to their sisters, prior to onset of disease. Findings of low IA in currently ill AN-R patients may represent a disease consequence, not a risk factor. Conclusions: Developmental child psychiatrists should direct their attention to disturbances of EC, which may be present prior to the onset of the disease.

Objective: Acute anorexia nervosa (AN) leads to reduced gray (GM) and white matter (WM) volume in the brain, which however improves again upon restoration of weight. Yet little is known about the extent and clinical correlates of these brain changes, nor do we know much about the time-course and completeness of their recovery. Methods: We conducted a meta-analysis and a qualitative review of all magnetic resonance imaging studies involving volume analyses of the brain in both acute and recovered AN. Results: We identified structural neuroimaging studies with a total of 214 acute AN patients and 177 weight-recovered AN patients. In acute AN, GM was reduced by 5.6% and WM by 3.8% compared to healthy controls (HC). Short-term weight recovery 2–5 months after admission resulted in restitution of about half of the GM aberrations and almost full WM recovery. After 2–8 years of remission GM and WM were nearly normalized, and differences to HC (GM: –1.0%, WM: –0.7%) were no longer significant, although small residual changes could not be ruled out. In the qualitative review some studies found GM volume loss to be associated with cognitive deficits and clinical prognosis. Conclusions: GM and WM were strongly reduced in acute AN. The completeness of brain volume rehabilitation remained equivocal.
