It has been claimed that functional somatic syndromes share a common etiology. This prospective population-based study assessed whether the same variables predict new onsets of irritable bowel syndrome (IBS), chronic fatigue syndrome (CFS) and fibromyalgia (FM).

The study included 152 180 adults in the Dutch Lifelines study who reported the presence/absence of relevant syndromes at baseline and follow-up. They were screened at baseline for physical and psychological disorders, socio-demographic, psycho-social and behavioral variables. At follow-up (mean 2.4 years) new onsets of each syndrome were identified by self-report. We performed separate analyses for the three syndromes including participants free of the relevant syndrome or its key symptom at baseline. LASSO logistic regressions were applied to identify which of the 102 baseline variables predicted new onsets of each syndrome.

There were 1595 (1.2%), 296 (0.2%) and 692 (0.5%) new onsets of IBS, CFS, and FM, respectively. LASSO logistic regression selected 26, 7 and 19 predictors for IBS, CFS and FM, respectively. Four predictors were shared by all three syndromes, four predicted IBS and FM and two predicted IBS and CFS but 28 predictors were specific to a single syndrome. CFS was more distinct from IBS and FM, which predicted each other.

Syndrome-specific predictors were more common than shared ones and these predictors might form a better starting point to unravel the heterogeneous etiologies of these syndromes than the current approach based on symptom patterns. The close relationship between IBS and FM is striking and requires further research.

Poverty may moderate the effect of treatment of depression in low-income countries.

To assess poverty and lack of empowerment as moderators of a cognitive-behavioural therapy (CBT)-based intervention for perinatal depression in rural Pakistan.

Using secondary analysis of data from a randomised controlled trial (trial registration: ISRCTN65316374) we identified predictors of depression at 1-year follow-up and moderators of the intervention (n=791).

Predictors of follow-up depression included household debt, the participant not being empowered to manage household finance and the interaction terms for these variables with the trial arm. Effect sizes for women with and without household debt were 0.80 and 0.55 respectively. The effect size for women in debt and not empowered financially was 0.94 compared with 0.50 for women with neither of these factors.

Our findings demonstrate the importance of household debt and lack of financial empowerment of women as important maintaining factors of depression in low-income countries and our locally developed intervention tackled these problems successfully.

Antidepressant drugs are widely used in the treatment of depression in people with chronic physical health problems.

To examine evidence related to efficacy, tolerability and safety of antidepressants for people with depression and with chronic physical health problems.

Meta-analyses of randomised controlled efficacy trials of antidepressants in depression in chronic physical health conditions. Systematic review of safety studies.

Sixty-three studies met inclusion criteria (5794 participants). In placebo-controlled studies, antidepressants showed a significant advantage in respect to remission and/or response: selective serotonin reuptake inhibitors (SSRIs) risk ratio (RR) = 0.81 (95% CI 0.73–0.91) for remission, RR = 0.83 (95% CI 0.71–0.97) for response; tricyclics RR = 0.70 (95% CI 0.40–1.25 (not significant)) for remission, RR = 0.55 (95% 0.43–0.70) for response. Both groups of drugs were less well tolerated than placebo (leaving study early due to adverse effects) for SSRIs RR = 1.80 (95% CI 1.16–2.78), for tricyclics RR = 2.00 (95% CI 0.99–3.57). Only SSRIs were shown to improve quality of life. Direct comparisons of SSRIs and tricyclics revealed no advantage for either group for remission, response, effect size or tolerability. Effectiveness studies suggest a neutral or beneficial effect on mortality for antidepressants in participants with recent myocardial infarction.

Antidepressants are efficacious and safe in the treatment of depression occurring in the context of chronic physical health problems. The SSRIs are probably the antidepressants of first choice given their demonstrable effect on quality of life and their apparent safety in cardiovascular disease.

British Pakistani women have a high prevalence of depression. There are no reported psychosocial interventions for depression in ethnic minorities in the UK.

To determine the efficacy of a social group intervention compared with antidepressants, and whether the combination of the two is more efficacious than either alone.

A total of 123 women with depression participated in the primary care-based cluster randomised controlled trial (ISRCTN19172148). Outcome measures were severity of depression (Hamilton Rating Scale for Depression), social functioning and satisfaction at 3 and 9 months.

Greater improvement in depression in the social intervention group and the combined treatment group compared with those receiving antidepressants alone fell short of significance. There was significantly greater improvement in social functioning in the social intervention and combined treatment groups than in the antidepressant group at both 3 and 9 months.

Pakistani women with depression found the social groups acceptable and their social function and satisfaction improved if they received social treatment compared with the receipt of antidepressants alone.
