Waitlist‐controlled trial of cognitive behavior therapy for hoarding disorder

Objective: This study investigated a multicomponent cognitive behavioral treatment (CBT) for hoarding based on a model proposed by Frost and colleagues and manualized in Steketee and Frost (2007). Method: Participants with clinically significant hoarding were recruited from the community and a university‐based anxiety clinic. Of the 46 patients randomly assigned to CBT or waitlist (WL), 40 completed the 12‐week assessment and 36 completed 26 sessions. Treatment included education and case formulation, motivational interviewing, skills training for organizing and problem solving, direct exposure to nonacquiring and discarding, and cognitive therapy. Measures included the Saving Inventory‐Revised (self‐report), Hoarding Rating Scale‐Interview, and measures of clinical global improvement. Between group repeated measures analyses using general linear modeling examined the effect of CBT versus WL on hoarding symptoms and moodstate after 12 weeks. Within group analyses examined pre‐post effects for all CBT participants combined after 26 sessions. Results: After 12 weeks, CBT participants benefited significantly more than WL patients on hoarding severity and mood with moderate effect sizes. After 26 sessions of CBT, participants showed significant reductions in hoarding symptoms with large effect sizes for most measures. At session 26, 71% of patients were considered improved on therapist clinical global improvement ratings and 81% of patients rated themselves improved; 41% of completers were clinically significantly improved. Conclusions: Multicomponent CBT was effective in treating hoarding. However, treatment refusal and compliance remain a concern, and further research with independent assessors is needed to establish treatment benefits and durability of gains.

Predictors of course in obsessive compulsive disorder

Systematic studies of course of illness in obsessive compulsive disorder (OCD) using standardized diagnostic criteria are relatively rare. In the present study, 100 patients diagnosed with OCD were prospectively followed for up to 5 years. Other comorbid conditions included anxiety disorders (76%), major depressive disorder (33%), and at least one personality disorder (33%), mainly in the anxious cluster. Approximately 20% of patients had full remission and 50% had partial remission during follow-up. Significant predictors of partial remission included being married and having lower global severity scores at intake; the presence of major depression was marginally predictive of poorer course. Adequate serotonergic medication was associated with worse course, but findings are likely spurious. Only marital status and global severity were retained as predictors in a final regression model. Findings are discussed with regard to sample characteristics and similarity to other reports on predictors of course and of treatment outcome.     

Family Informants’ Perceptions of Insight in Compulsive Hoarding

Existing psychological and pharmacological interventions for obsessive-compulsive disorder have not been particularly successful for compulsive hoarding, perhaps due in part to poor insight on the part of sufferers. Individuals with compulsive hoarding problems commonly display lack of awareness of the severity of their behavior, sometimes denying that they have a problem and often resisting intervention attempts and failing to follow through with therapeutic assignments. Using an internet-based survey, family and friends of individuals with reported hoarding problems (family/friend informants, N = 584) provided ratings of the hoarder’s level of insight. They also made several ratings of the severity of the person’s hoarding behavior, then rated the same items again with regard to how they thought the hoarder would respond to the items. Family/friend informants described the hoarder on average as having fair to poor insight. More than half were described as having “poor insight” or “lacks insight/delusional,” substantially worse insight than found in samples of OCD clinic patients using the same measure. Family/friend informants’ ratings of hoarding severity were significantly greater than were their estimates of the hoarder’s ratings. Hoarders described as showing less distress about the hoarding were described as showing poorer insight. These results suggest that compulsive hoarding is characterized by poor insight into the severity of the problem. Treatment development might need to emphasize strategies to bolster awareness, insight, and motivation.     

T cells reactive with the NC16A domain of BP180 are present in vulval lichen sclerosus and lichen planus

Background Lichen sclerosus (LS) is a chronic inflammatory skin condition. The recent demonstration of circulating autoantibodies to extracellular matrix protein 1 and to basement membrane zone (BMZ) components, chiefly BP180, suggests that autoimmunity to these components might contribute to pathogenesis. However, there is no binding of autoantibodies in vivo and as LS is characterized by a lymphocytic infiltrate, it seems likely that LS is mediated, in part, by antigen‐specific lymphocytes. Similar mechanisms may apply to vulval lichen planus (LP), an interface dermatitis, with clinical and immunological overlap with LS. Objectives This study aims to test the hypothesis that T cells reactive with the NC16A domain of BP180 are present in the peripheral blood of patients with vulval LS and LP. Methods Isolated peripheral blood mononuclear cells from 14 patients with vulval LS, 5 with vulval LP and 4 healthy controls were grown in vitro. We examined for immunogenicity of overlapping peptides spanning the NC16A domain of BP180 using interferon‐γ enzyme‐linked immunospot assay (ELIspot) on the cultured T‐cell lines. BMZ antibodies were assayed, HLA type determined and clinical parameters noted. Results Significant interferon‐γ production was observed in response to the NC16A peptides in 6 of the 14 vulval LS and 2 of the 5 LP patients, but not in the control subjects. There was an associated autoantibody response to BP180 in 3 LS and 1 LP patient with T‐cell responses. These data suggest that in some vulval LS and LP patients, NC16A domain‐specific T cells circulate at sufficiently high frequency to be detectable in vitro and show rapid effector function. There was no association with HLA type or clinical parameters. Conclusion We have demonstrated that in > 40% of our vulval LS and LP patients, the NC16A domain of BP180 is a target for circulating T cells, and in vulval LS and LP there are associated autoantibodies to BP180.
