Objectives: The aim of this article is to estimate the prevalence of mental disorders in patients in primary care centers in an urban area of Madrid and to study possible associated risk factors. Methods: Cross-sectional month prevalence was evaluated in two phases in an urban area of Madrid. The sample for the first phase included 635 individuals (aged 18–65 years), and the second phase included 320 individuals. Socio-demographic variables (age, sex, educational level, living conditions and country of origin) and clinical variables (psychiatric diagnosis and level of psychosocial stress) were studied. The instruments used for screening were the General Health Questionnaire (GHQ)-28 item questionnaire and the MULTICAGE-CAD 4test. The Mini International Neuropsychiatric Interview (M.I.N.I.) was used in the second phase (in 'possible cases' and 20% of the 'non-cases'). Prevalence was calculated using weighted logistic regression with the observed sampling fractions of the patients in study phase 2 as sample weights. Results and conclusions: The month prevalence of mental disorders was 31.3% (95% confidence interval (CI) = [27.6, 35.2]). Anxiety disorders were the most frequent diagnoses with a prevalence of 22.4% (95% CI = [17.8, 27.1]), followed by depressive disorders (16.6%; 95% CI = [12.9, 20.3]), substance abuse or dependence disorders (5.6%; 95% CI = [3.2, 6.9]) and posttraumatic stress disorder (PTSD; 4.4%; 95% CI = [2.0, 2.8]). Factors associated with mental disorders were the presence of stressful life events in the previous 12 months, Latin American region of origin, being woman aged 25 and 34 years and having a low education level.

5 p.-2 fig. ; [Background] Glomerulonephritis is one of the most severe complications of lupus, a systemic disease with multi-organ involvement, with tissue damage produced mainly by complement activation. As a result of this activation, patients with active lupus present hypocomplementemia during disease flares, but C3 and C4 levels are recovered between episodes. ; [Case presentation] We present a patient who suffered two lupus nephritis episodes in 5 years, achieving complete remission with treatment after both of them, but with C3 levels persistently below normal range. Genetic study revealed that the patient carried a mutation in heterozygosis in the C3 gene. Serial sera samples were analyzed, and autoantibodies to complement alternative pathway proteins (Factor I, Factor B, C3 and Properdin) were found. Functional assays showed that these autoantibodies cause alternative pathway activation. ; [Conclusion] This case is the first reported of a heterozygous C3 mutation associated with lupus nephritis and autoantibodies against complement alternative pathway proteins (Factor I, Factor B, C3 and Properdin).These autoantibodies cause activation of this pathway and this fact could explain that the tissue damage is restricted to the kidney. ; This work was funded by Spanish government, Ministerio de Economía y Competitividad (grant SAF2012-38636), Autonomous region of Madrid (S2010/BMD-2316 to SRdeC y MLT) and Sociedad Española de Nefrología Fundación Senefro to MLT. ; Peer reviewed
