Pharmacological and psychotherapeutic interventions for obsessivecompulsive disorder in adults, children and adolescents: a systematic review and network meta-analysis. Skapinakis P, Caldwell DM, Hollingworth W, Bryden P, Fineberg NA, et al. Lancet Psychiatry. 2016 Aug; 3(8): 730 -9. Most psychotherapy trials included patients who were taking medications. In adults, psychotherapies, clomipramine, SSRIs or combinations of these are all effective. There were few studies in children and adolescents; psychotherapies as monotherapy or combined with SSRIs were more likely to be effective. Future RCTs should improve their design, in particular for psychotherapy or combined interventions.
STEPPED CARE MODEL Who is responsible for care? STEP 6 Inpatient care or intensive treatment programmes (national). STEP 5 Multidisciplinary teams with specific expertise in management of OCD (regional). STEP 4 local multidisciplinary care (GP or psychiatrist). STEP 3 GPs and primary care team, primary care mental health worker, family support team. STEP 2 GPs, practice nurses, school health advisors STEP 1 Individuals, public organisations, NHS

Can we predict outcomes on an individual basis?
Early improvement as an indicator of treatment response in OCD? Implications for early-treatment decision-making. Da Conceicao DL 2013, J Psychiat Res Nov; 47(11): 1700 -7 A pragmatic naturalistic 12 -week SRI trial with 128 subjects. Early improvement (>= 20% reduction in baseline Y-BOCS) at 4 weeks was the best predictor of treatment response (>=35% Y-BOCS improvement) at 12 weeks (OR = 1. 05, p < 0. 0001). Only 20% of patients who did not improve at 4 weeks were responders after 12 weeks. But, only 55% who showed early improvement ended up responders at 12 weeks.
Five-year course of obsessive-compulsive disorder: predictors of remission and relapse. Eisen JL et al. , J Clin Psychiatry. 2013 Mar; 74(3): 233 -9. 213 adults with DSM-IV OCD Recruited between 2001 -6 OCD symptoms assessed annually over 5 -year follow-up - 39% participants entered either partial (22. 1%) or full (16. 9%) remission. - Obsessions regarding harm nearly twice as likely to remit (P <. 05) - Other positive predictors of remission included lower OCD severity (P < . 0001) and shorter duration of illness (P <. 0001) - Primary hoarding sig less likely to remit (2 of 21 participants (9. 5%). - 59% participants who remitted subsequently relapsed. - Participants with obsessive-compulsive personality disorder more than twice as likely to relapse (P <. 005). - Participants also more likely to relapse if they experienced partial remission versus full remission (70% vs 45%; P <. 05)
Long-term course of paediatric OCD: 3 years of prospective follow-up. Mancebo MC et al Compr Psychiatry. 2014 Oct; 55(7): 1498 -504. • 60 youth and their parents • Annual follow-up interviews for 3 years - 80% patients achieved either partial (53%) or full (27%) remission - Better functioning at intake and a shorter latency to initial OCD treatment were associated with faster onset of remission (P<. 001). - 21% of those who remitted subsequently relapsed (mean 88 wk f-up) CONCLUSIONS • Remission is more likely among youth versus adults with OCD. • Treatment early in the course of illness and before substantial impact on functioning predicts a better course.

How to treat resistant OCD?
SRI-resistant OCD: a pharmacological algorithm Obsessive-Compulsive and Related Disorders. Reghunandanan S, Fineberg NA, Stein DS. OUP. 2015 in press Review diagnosis Check adherence First-line treatment SSRI, maximal dose, 12 weeks (1) Switch SSRI or clomipramine, maximal dose, 12 weeks Repeat (1) Add haloperidol Increase dose beyond formulary limits Intravenous SSRI or clomipramine NOVEL AGENTS Add second generation antipsychotic Combine clomipramine and SSRIs
Higher-dose SSRI monotherapy for resistant OCD? Ninan et al J Clin Psych 2006 • 66 OCD non-responders to 16 weeks of sertraline, randomly assigned: • 12 weeks high-dose sertraline (250 -400 mg/day, mean = 357 mg, N = 30) outperformed sertraline 200 mg/day (N = 36) on YBOCS, NIMH Global OC Scale, CGI-I. • Responder rates not significantly different between groups, either on completer analysis ( 34% vs. 52%) or endpoint analysis (33% vs. 40%). • Both treatments showed similar adverse event rates. • Higher than labelled SSRI doses may be a treatment option for OCD patients who fail to respond to standard acute treatment.

Arnsten AF, Casey BJ. Biological Psychiatry, 2011 Jun 15. PMID: 21640860 In OCRD, convergent evidence suggests insufficient top-down control in pre-frontal loops coupled with excess habit generation in dorsal striatum
Somatic treatments in highly refractory OCD ECT: Insufficient evidence to recommend ECT for OCD, given potential associated risks (APA Practice Guidelines on OCD; Koran et al 2007). r. TMS: RCTs (Mantovani et al. , 2010; Gomes et al. , 2012) and a meta-analysis including 282 subjects (Berlim et al 2013) suggest promising results for OFC/SMA in comparison to sham r. TMS. Though promising, r. TMS remains experimental. DBS: stimulating ventral striatum/ventral capsule or sub-thalamic nucleus may produce therapeutic effects by modulating the cortico-striatal neurocircuitry that is widely proposed to mediate OCD (Bourne et al 2012). Though promising, DBS remains experimental. Ablative neurosurgery: (ant. cingulotomy, ant. capsulotomy) remains the last resort for very severely ill patients who do not respond to expert delivered trials of pharmacotherapy and CBT of optimal dosage/content, duration, and mode of delivery as assessed by experienced experts in specialty treatments for OCD. (Lopez AC et al JAMA Psychiatry. doi: 10. 1001/jamapsychiatry. 2014. 1193).
RCTs OF r. TMS IN RESISTANT OCD Pooled Hedges' g for pre-post Y-BOCS = 0. 59 (p = 0. 006). N=10; n=282. Response rates = 35% and 13% for active and sham r. TMS, respectively (OR = 3. 4, p = 0. 002). Non-DLPFC targets (OFC, SMA) the most promising on subgroup analysis BUT Studies are small with differing sample characteristics, duration, stimulation site, frequency etc Berlim et al. , Journal of Psychiatry Research 2013
Conclusions • Treatment effect on SRI partial and dose and time dependent • Long-term SSRI protects against relapse • Combining SSRI + ERP may confer added benefit • Limitations of existing treatment • Novel strategies required – Outcome predictors? – Circuitries? – New compounds? – CRT/Habit-reversal psychotherapy? – Brain Stimulation?

Cognitive remediation therapy (CRT); a role in OCRD? Developed for ED, CRT targets attention to detail and set-shifting, encourages flexible behaviour, motivation and perceived ability to change. • In ED, CRT improved Qo. L and dropout rates when combined with CBT. Cognitive inflexibility predicted a better response to CRT. Dingemans AE et al. , Psychother Psychosom 2014. • In OCD, CRT improved OC symptoms as well as executive skills and cognitive flexibility in pilot studies. Buhlmann U et al, Psychiatry Res. 2006. Park HS et al. , Psychiatry Clin Neurosci. 2006 Individual CRT maybe a beneficial adjunct to TAU in disorders characterized by cognitive inflexibility - or possibly excessive habit
