A pilot study to address the mental health of persons living with lymphatic filariasis in Léogâne, Haiti: Implementing a chronic disease self-management program using a stepped-wedge cluster design.

BACKGROUND: Neglected tropical diseases (NTDs) inflict significant comorbid disability on the most vulnerable communities; yet interventions targeting the mental health of affected communities are lacking. A pilot study to assess the effectiveness of a chronic disease self-management program (CDSMP) was introduced to lymphatic filariasis peer support groups in Léogâne, Haiti. METHODS: Using a closed-cohort stepped-wedge cluster trial design, Hope Clubs were assigned into Arm 1 (n=118 members) and Arm 2 (n=92). Household surveys, measuring self-rated health, depression, disease self-efficacy, perceived social support, and quality of life, were conducted at baseline (before CDSMP); midpoint (after Arm 1/before Arm 2 completed CDSMP); and endpoint (after CDSMP). Non-Hope Club member patients (n=74) were evaluated at baseline for comparison. RESULTS: Fifty percent of Hope Club members (Arm 1: 48.3%, Arm 2: 52.2%) screened positive for depression at baseline, compared with 36.5% of non-Hope Club members. No statistically significant differences were found in outcome measures between intervention observation periods. At endpoint, depressive illness reduced to 28.7% (Arm 1) and 27.6% (Arm 2). CONCLUSIONS: The intervention was feasible to integrate into Hope Clubs, showed overall positive effects and reduced depressive symptoms. More studies are needed to evaluate the efficacy of implementing CDSMP in the NTD context. CONTEXTE: Les maladies tropicales négligées (MTN) infligent d'importantes incapacités comorbides aux communautés les plus vulnérables; pourtant, les interventions ciblant la santé mentale des communautés affectées font défaut. Une étude pilote visant à évaluer l'efficacité d'un programme d'autogestion des maladies chroniques (CDSMP) a été introduite dans des groupes de soutien par les pairs pour la filariose lymphatique à Léogâne, en Haïti. MÉTHODES: Dans le cadre d'un essai en grappe à cohorte fermée, les clubs Hope ont été répartis entre le bras 1 (n=118 membres) et le bras 2 (n=92). Des enquêtes auprès des ménages, mesurant l'auto-évaluation de la santé, la dépression, l'auto-efficacité face à la maladie, le soutien social perçu et la qualité de vie, ont été menées au départ (avant le CDSMP), à mi-parcours (après que le bras 1 / avant que le bras 2 ait terminé le CDSMP) et à la fin (après le CDSMP). Les patients non membres du Hope Club (n=74) ont été évalués au début de l'étude à des fins de comparaison. RÉSULTATS: Cinquante pourcent des membres du Hope Club (bras 1 : 48,3%, bras 2 : 52,2%) ont été dépistés positifs pour la dépression au début de l'étude, contre 36,5% des non-membres du Hope Club. Aucune différence statistiquement significative n'a été constatée dans les mesures des résultats entre les périodes d'observation de l'intervention. À la fin de l'étude, la maladie dépressive était réduite à 28,7% (bras 1) et 27,6% (bras 2). CONCLUSIONS: L'intervention a pu être intégrée dans les clubs Hope, elle a montré des effets globalement positifs et a permis de réduire les symptômes dépressifs. D'autres études sont nécessaires pour évaluer l'efficacité de la mise en œuvre du CDSMP dans le contexte des MTD. ANTECEDENTES: Las enfermedades tropicales desatendidas (ETDs) infligen una importante discapacidad comórbida a las comunidades más vulnerables; sin embargo, faltan intervenciones dirigidas a la salud mental de las comunidades afectadas. Se introdujo un estudio piloto para evaluar la eficacia de un programa de autogestión de enfermedades crónicas (CDSMP, por sus siglas en inglés) en grupos de apoyo entre pares de filariasis linfática en Léogâne, Haití. MÉTODOS: Utilizando un diseño de ensayo por conglomerados de cohortes cerradas escalonadas, los Clubes Esperanza fueron asignados al Grupo 1 (n=118 miembros) y al Grupo 2 (n=92). Se realizaron encuestas en los hogares para medir la autoevaluación de la salud, la depresión, la autoeficacia frente a la enfermedad, el apoyo social percibido y la calidad de vida en la línea de base (antes del CDSMP), en el punto medio (después de que el Grupo 1/antes de que el Grupo 2 completara el CDSMP) y en el punto final (después del CDSMP). Los pacientes que no pertenecían al Club Esperanza (n=74) fueron evaluados al inicio del estudio a modo de comparación. RESULTADOS: El 50% de los miembros del Club Esperanza (Grupo 1: 48,3%, Grupo 2: 52,2%) dieron positivo en depresión al inicio del estudio, en comparación con el 36,5% de los no miembros del Club Esperanza. No se encontraron diferencias estadísticamente significativas en las medidas de resultado entre los periodos de observación de la intervención. Al final, la enfermedad depresiva se redujo al 28,7% (Grupo 1) y al 27,6% (Grupo 2). CONCLUSIONES: La intervención fue factible de integrar en los Clubes Esperanza, mostróefectos positivos generales y redujo los síntomas depresivos. Se necesitan más estudios para evaluar la eficacia de la aplicación del CDSMP en el contexto de las ETD.

Healing invisible wounds and rebuilding livelihoods: Emerging lessons for combining livelihood and psychosocial support in fragile and conflict-affected settings.

Populations living in fragile and conflict-affected settings (FCS) endure serious hardship, often including witnessing or having direct exposure to violence. These experiences adversely affect the mind, body, and spirit, and diminish the capacity of individuals and communities to take full advantage of economic empowerment opportunities. A small but growing number of programs have begun to combine psychosocial support with livelihood support in FCS, with some promising indication that this combination can enhance project outcomes. This paper assesses evidence to generate a 'hypothesis of change' that combining psychosocial with livelihood support can improve development outcomes in FCS. We reviewed evaluations of three categories of programs: (i) those that provide psychosocial support and assess impact on economic empowerment, (ii) those that provide livelihood support and assess impact on psychosocial well-being, and (iii) those that combine both types of support and assess impact on one or both outcomes.

The cytokine model of schizophrenia: emerging therapeutic strategies.

We discuss the rationale for a trial of a novel biological immunotherapy in schizophrenia (SCZ). Available antipsychotic treatments for SCZ are often limited by partial effectiveness and significant side effects. The search for novel medications is of high priority. All current antipsychotics function primarily by blocking D2-type dopamine receptors. An emerging theory of SCZ postulates disturbances of cytokines and inflammatory mediators (i.e., the cytokine model), possibly originating in part from infectious exposures. Cytokines are one of the most important components of the immune system that orchestrate the response to infectious and other exogenous insults. Preclinical models of SCZ support a convergence between a role for certain cytokines in the pathophysiology of SCZ and major neurochemical postulates of the disorder, including the dopamine and glutamate hypotheses. Several cytokines are elevated in plasma in SCZ, and positron emission tomography studies have shown active inflammation in the brains of patients with psychosis. Treatment studies of anti-inflammatory agents, such as celecoxib and aspirin, in patients with SCZ have provided further support for neuroinflammation in this disorder. The development of approved biological therapies for autoimmune diseases provides new opportunities to target cytokine signaling directly as a novel treatment strategy in SCZ. In addition, advances in imaging, immunology, and psychopharmacology have paved the way for using measures of target engagement of neuroimmune components that would facilitate the identification of patient subgroups who are most likely to benefit from cytokine modulation.
