Multimodal Psychotherapeutic Inpatient Therapy of Depression Is Successful in Patients With High Cytokine Production.

Objective: In experimental settings, systemically elevated inflammation markers interfere with major depression treatment. In German healthcare, compulsory national health insurance covers treatment of a wide variety of depressive disorders, if it follows evidence-based medicine guidelines combining recommended therapies. To date, little is known about the relevance of immune system cytokine production with regard to real-world clinical care for patients with moderate depression. Methods: Seventy three patients with moderate depression subjected to multimodal psychotherapeutic inpatient therapy (mPT) following a psychodynamic concept at a German university hospital were included. As a primary outcome, mPT success, evidenced by delta HADS "depression," was analyzed according to tumor necrosis factor alpha (TNFα) production by peripheral blood mononuclear cells (PBMC) after phytohemagglutinin (PHA) challenge at baseline. Secondary outcomes addressed the inflammatory response and mental health comparing high and low TNFα-producers. Results: First, higher PBMC TNFα production at baseline predicted a better mPT-outcome (R 2 0.162, p = 0.014). Second, patients with high TNFα (hTNF) at baseline produced significantly more acute inflammatory cytokines [interleukin (IL)1ß, IL6), TH1/TH2 cytokines [interferon gamma (IFNγ), IL4] as well as eotaxin and IL2 compared to low TNFα producers (lTNF) (Cohen's ds between -0.532 and -1.013). Demographic data, diagnosis subtype-distribution, medication, systemic inflammation markers [C-reactive protein (CRP), high mobility group box 1 (HMGB1), leptin], anxiety and depression (HADS) did not differ. From baseline to mPT-discharge, HADS "depression" decreased in both hTNF (11.31 to 5.47, p = 0.001, d = 1.184) and lTNF patients (11.50-7.92, p = 0.001, d = -0.765), while PBMC cytokine production decreased significantly in hTNF (Cohen's ds between -0.304 and -0.345) with a significant group by time interaction for TH1/TH2 ratio. At the end of therapy, comparison of TNF groups revealed significantly lower depression-scores in hTNF compared to lTNF patients (5.47 compared to 7.92, p = 0.035, d = 0.504). Conclusions: Our study demonstrates successful treatment of depression in a clinical care setting using multimodal psychotherapy based on a psychodynamic concept following guideline recommendation. The greatest improvement in patient depression was linked to the highest production of TNFα by PBMCs at baseline. Our study contributes to the definition of patient subpopulations with differing cytokine responses that are related to succesful treatment of depression.

Progranulin serum levels and gene expression in subcutaneous vs visceral adipose tissue of severely obese patients undergoing bariatric surgery.

BACKGROUND: Progranulin represents an adipokine putatively mediating insulin resistance and inflammation. Data in humans are sparse, and the source of circulating progranulin in obesity is unknown. OBJECTIVES: Serum progranulin concentrations and subcutaneous (sc) as well as visceral (vis) adipose tissue (AT) progranulin expression were quantified in a large cohort of patients with obesity undergoing bariatric surgery (BS) (n = 153) or a low-calorie diet (LCD) (n = 121). COHORTS AND METHODS: Paired serum and AT mRNA samples were obtained from patients with severe obesity undergoing BS (ROBS cohort; Research in Obesity and Bariatric Surgery). Serum progranulin was measured by ELISA in both cohorts, and AT mRNA expression was analysed by quantitative real-time PCR in bariatric patients. RESULTS: There was no gender-specific effect in serum progranulin or AT progranulin expression. Importantly, circulating progranulin was independent from adipose tissue gene expression in paired samples. sc AT progranulin expression was higher than in vis AT (P = 0.027), and there was a positive correlation between sc AT and vis AT gene expression (P < 0.001; r = +0.34). Serum progranulin strongly and rapidly increased after BS within 3 days and remained elevated up to 12 months. Serum progranulin was strongly correlated with serum CTRP-3 levels. CONCLUSIONS: The present study provides detailed progranulin gene expression data in sc and vis AT in a large, prospective and observational cohort of patients with severe obesity. Serum progranulin concentrations are not predicted by sc or vis AT progranulin gene expression. Thus, AT seems not to be the main source of circulating progranulin levels in obesity.

Culture and healthcare in medical education: migrants' health and beyond.

One of the main challenges for teaching programs on immigration, ethnic diversity and health is to transform the commonplace notion of "culture" into a helpful tool for medical training and practice. This paper presents the teaching approach of an interdisciplinary course on "migrants' health" established at the University of Giessen since 2004, which has recently been complemented by a thematically related collaboration with two universities in Latin America (Ecuador, Peru). The overall goal is to translate the abstract philosophy of "think global and teach local" into medical practice, and to provide students with the insights, attitudes and skills needed for a fruitful use of concepts like "culture", "ethnicity" and "migration background". A key feature of the course is the strong commitment to ethnography as an important means for looking under the surface of superficial attributions to culture, and for grasping the interplay of medicine and health with cultural, social, religious, economic and legal aspects in its particular local and/or individual shape. Three elements of the course are presented to illustrate this approach: First, a unit on Islam and Medicine, as important parts of the local immigrant community are Muslims. The second one deals with psychosomatic aspects, because in case of immigrants, complex symptoms and disease representations like somatisation are easily misinterpreted as "cultural". The third element consists of a unit with specialized social workers form outside the university, who provide direct insights into the living conditions and health problems of local immigrant communities.
