Anti-tumour necrosis factor-α therapy for severe enteropathy in patients with common variable immunodeficiency (CVID)

We present three common variable immunodeficiency (CVID) patients with
severe inflammatory bowel disease of unknown aetiology, resistant to steroid
treatment, treated with infliximab.After exclusion of any infection, infliximab
was given at a dose of 5 mg/kg every 4 weeks for a 3 month induction followed
by every 4–8 weeks depending on clinical response. Two of these patients had
predominantly small bowel disease; they both showed clinical response to
infliximab with weight gain and improvement of quality of life scores. The
third patient had large bowel involvement with profuse watery diarrhea; this
patient improved dramatically within 48 hours of having infliximab
treatment. All three patients have been maintained on infliximab treatment
for between 5 and 53 months (mean 37 months) with no evidence of increased
susceptibility to infections in the patients with small bowel disease, although
the third patient developed two urinary tract infections and a herpes zoster
infection following therapy. This is the first small case series to show that
infliximab is a useful addition to current therapy in this rare group of patients
with potentially life threatening enteritis.

Mind and body: how the health of the body impacts on neuropsychiatry

It has long been established in traditional forms of medicine and in anecdotal knowledge that the health of the body and the mind are inextricably linked. Strong and continually developing evidence now suggests a link between disorders which involve Hypothalamic-Pituitary-Adrenal axis (HPA) dysregulation and the risk of developing psychiatric disease. For instance, adverse or excessive responses to stressful experiences are built into the diagnostic criteria for several psychiatric disorders, including depression and anxiety disorders. Interestingly, peripheral disorders such as metabolic disorders and cardiovascular diseases are also associated with HPA changes. Furthermore, many other systemic disorders associated with a higher incidence of psychiatric disease involve a significant inflammatory component. In fact, inflammatory and endocrine pathways seem to interact in both the periphery and the central nervous system (CNS) to potentiate states of psychiatric dysfunction. This review synthesizes clinical and animal data looking at interactions between peripheral and central factors, developing an understanding at the molecular and cellular level of how processes in the entire body can impact on mental state and psychiatric health.

Anti-inflammatory agents in the treatment of bipolar depression: a systematic review and meta-analysis

OBJECTIVE: Inflammation has been implicated in the risk, pathophysiology, and progression of mood disorders and, as such, has become a target of interest in the treatment of bipolar disorder (BD). Therefore, the objective of the current qualitative and quantitative review was to determine the overall antidepressant effect of adjunctive anti-inflammatory agents in the treatment of bipolar depression. METHODS: Completed and ongoing clinical trials of anti-inflammatory agents for BD published prior to 15 May 15 2015 were identified through searching the PubMed, Embase, PsychINFO, and Clinicaltrials.gov databases. Data from randomized controlled trials (RCTs) assessing the antidepressant effect of adjunctive mechanistically diverse anti-inflammatory agents were pooled to determine standard mean differences (SMDs) compared with standard therapy alone. RESULTS: Ten RCTs were identified for qualitative review. Eight RCTs (n = 312) assessing adjunctive nonsteroidal anti-inflammatory drugs (n = 53), omega-3 polyunsaturated fatty acids (n = 140), N-acetylcysteine (n = 76), and pioglitazone (n = 44) in the treatment of BD met the inclusion criteria for quantitative analysis. The overall effect size of adjunctive anti-inflammatory agents on depressive symptoms was -0.40 (95% confidence interval -0.14 to -0.65, p = 0.002), indicative of a moderate and statistically significant antidepressant effect. The heterogeneity of the pooled sample was low (I² = 14%, p = 0.32). No manic/hypomanic induction or significant treatment-emergent adverse events were reported. CONCLUSIONS: Overall, a moderate antidepressant effect was observed for adjunctive anti-inflammatory agents compared with conventional therapy alone in the treatment of bipolar depression. The small number of studies, diversity of agents, and small sample sizes limited interpretation of the current analysis.
