ABSTRACT<br />

Objective: <strong>Body</strong> dysmorphic disorder (BDD),<br />

a preoccupation with imag<strong>in</strong>ed ugl<strong>in</strong>ess, is a disabl<strong>in</strong>g<br />

condition that seems to respond preferentially<br />

to selective seroton<strong>in</strong> reuptake <strong>in</strong>hibitors. This<br />

open-label trial exam<strong>in</strong>es venlafax<strong>in</strong>e’s efficacy <strong>in</strong><br />

BDD and is the first known study <strong>of</strong> this seroton<strong>in</strong>norep<strong>in</strong>ephr<strong>in</strong>e<br />

reuptake <strong>in</strong>hibitor <strong>in</strong> BDD.<br />

Methods: A total <strong>of</strong> 17 BDD patients 16–65<br />

years <strong>of</strong> age entered and 11 completed a 12–16<br />

week open-label trial <strong>of</strong> venlafax<strong>in</strong>e. Participants<br />

were treated with venlafax<strong>in</strong>e until a therapeutic<br />

dose (m<strong>in</strong>imum <strong>of</strong> 150 mg/day) was reached<br />

and then ma<strong>in</strong>ta<strong>in</strong>ed at that dose for 8 weeks.<br />

Key outcome measures were the Yale-Brown<br />

Obsessive-Compulsive Scale Modified for<br />

<strong>Body</strong> <strong>Dysmorphic</strong> <strong>Disorder</strong> and Cl<strong>in</strong>ical Global<br />

Impressions-Improvement scale.<br />

Results: <strong>Venlafax<strong>in</strong>e</strong> was found to be effective<br />

<strong>in</strong> lessen<strong>in</strong>g the specific symptoms and global<br />

severity <strong>of</strong> BDD. Paired t-tests were used to<br />

compare basel<strong>in</strong>e and f<strong>in</strong>al rat<strong>in</strong>gs on the Yale-<br />

Brown Obsessive-Compulsive Scale Modified<br />

for <strong>Body</strong> <strong>Dysmorphic</strong> <strong>Disorder</strong> total, obsessions,<br />

Needs Assessment<br />

<strong>Body</strong> dysmorphic disorder (BDD) is a serious, treatment-refractory disorder<br />

for which there are few studied treatments. This article provides<br />

the first published data on venlafax<strong>in</strong>e treatment <strong>of</strong> BDD. In addition,<br />

this article summarizes available data on pharmacological treatments<br />

for BDD and how treatment for BDD may differ from treatment <strong>of</strong> OCD.<br />

Learn<strong>in</strong>g Objectives<br />

At the end <strong>of</strong> this activity, the participant should be able to:<br />

• Select a first-l<strong>in</strong>e pharmacologic treatment for body dysmorphic<br />

disorder.<br />

• Dose venlafax<strong>in</strong>e appropriately.<br />

• Understand what treatment response to expect over the first few<br />

months <strong>of</strong> treatment.<br />

Target Audience: Neurologists and psychiatrists<br />

INTRODUCTION<br />

<strong>Body</strong> dysmorphic disorder (BDD) is a disabl<strong>in</strong>g<br />

condition <strong>in</strong> which normal-appear<strong>in</strong>g <strong>in</strong>dividuals<br />

are pa<strong>in</strong>fully preoccupied with an imag<strong>in</strong>ed or<br />

slight defect <strong>in</strong> their appearance. It is a somat<strong>of</strong>orm<br />

disorder that some consider to be an obsessive-compulsive<br />

spectrum disorder 1,2 because <strong>of</strong><br />

its similarities to obsessive-compulsive disorder<br />

(OCD) <strong>in</strong> symptoms, course, age <strong>of</strong> onset, 3,4<br />

and response to primary pharmacologic 5 and<br />

psychological treatments. 6 BDD and OCD differ<br />

primarily <strong>in</strong> the focus <strong>of</strong> their obsessive th<strong>in</strong>k<strong>in</strong>g<br />

and compulsive behaviors and <strong>in</strong> the degree <strong>of</strong><br />

<strong>in</strong>sight, with BDD patients hav<strong>in</strong>g notably poorer<br />

<strong>in</strong>sight than OCD patients. 7 BDD <strong>of</strong>ten leads to<br />

seriously impaired social and occupational function<strong>in</strong>g,<br />

high rates <strong>of</strong> hospitalization, suicidal<br />

ideation, and suicide attempts. 3,4,8-12<br />

Research on pharmacotherapy for BDD is<br />

limited but available reports <strong>in</strong>dicate that BDD<br />

seems to respond to the same first-l<strong>in</strong>e medications<br />

as OCD, specifically the selective seroton<strong>in</strong><br />

reuptake <strong>in</strong>hibitors (SSRIs). <strong>Open</strong>-label<br />

treatment studies and case series 11,13-15 suggest<br />

that SSRIs, such as fluvoxam<strong>in</strong>e, fluoxet<strong>in</strong>e, and<br />

citalopram, can reduce BDD symptoms. More<br />

importantly, controlled studies have found that<br />

the seroton<strong>in</strong> norep<strong>in</strong>ephr<strong>in</strong>e reuptake <strong>in</strong>hibitor<br />

(SNRI) clomipram<strong>in</strong>e 16 and the SSRI fluoxet<strong>in</strong>e 17<br />

can be effective <strong>in</strong> ameliorat<strong>in</strong>g BDD symptoms.<br />

In a double-bl<strong>in</strong>d, controlled pharmacologic<br />

treatment <strong>in</strong>vestigation <strong>of</strong> BDD, Hollander<br />

and colleagues 16 concluded that the SNRI clomipram<strong>in</strong>e<br />

was significantly superior to desip-<br />

Orig<strong>in</strong>al Research<br />

ram<strong>in</strong>e, a selective norep<strong>in</strong>ephr<strong>in</strong>e reuptake<br />

<strong>in</strong>hibitor <strong>in</strong> reduc<strong>in</strong>g overall BDD severity and<br />

specific BDD symptoms; the medication was<br />

equally effective for patients with poor <strong>in</strong>sight<br />

as those with good <strong>in</strong>sight. Phillips and colleagues’<br />

17 study <strong>of</strong> fluoxet<strong>in</strong>e likewise showed<br />

efficacy <strong>in</strong> BDD regardless <strong>of</strong> level <strong>of</strong> <strong>in</strong>sight.<br />

<strong>Venlafax<strong>in</strong>e</strong>, another SNRI, acts similarly<br />

to clomipram<strong>in</strong>e and has been shown to have<br />

fewer side effects and a lower risk <strong>of</strong> adverse<br />

effects than other, older antidepressants, <strong>in</strong>clud<strong>in</strong>g<br />

clomipram<strong>in</strong>e. 18-20 <strong>Venlafax<strong>in</strong>e</strong> is not associated<br />

with the antichol<strong>in</strong>ergic, antihistam<strong>in</strong>e, and<br />

α-adrenergic side effects <strong>of</strong> clomipram<strong>in</strong>e. 21 Case<br />

study and open-label data 21-26 as well as two double-bl<strong>in</strong>d<br />

active comparison studies 27,28 suggest<br />

that venlafax<strong>in</strong>e may be an effective treatment<br />

for OCD. However, one small, placebo-controlled<br />

trial 18,29 failed to show venlafax<strong>in</strong>e efficacy <strong>in</strong><br />

OCD, possibly due to the small sample size and<br />

other methodological limitations. To date, there<br />

are no published studies regard<strong>in</strong>g the efficacy<br />

<strong>of</strong> venlafax<strong>in</strong>e <strong>in</strong> BDD and, given the efficacy<br />

<strong>of</strong> the SNRI clomipram<strong>in</strong>e, may represent an<br />

important option <strong>in</strong> treat<strong>in</strong>g BDD.<br />

Additional research is needed on pharmacotherapy<br />

for BDD. Recent publications have suggested<br />

the augmentation with antipsychotics<br />

may not be as helpful <strong>in</strong> BDD as <strong>in</strong> OCD. The<br />

typical antipsychotic pimozide, although one<br />

<strong>of</strong> the earliest agents shown to be effective <strong>in</strong><br />

monosymptomatic hypochondriasis, failed to<br />

demonstrate any efficacy <strong>in</strong> BDD <strong>in</strong> a placebocontrolled<br />

trial. 30 A small study <strong>of</strong> the atypical<br />

antipsychotic olanzap<strong>in</strong>e 31 showed efficacy <strong>in</strong><br />

only two <strong>of</strong> n<strong>in</strong>e BDD patients.<br />

We hypothesized that venlafax<strong>in</strong>e would be<br />

an effective medication for adults with BDD<br />

s<strong>in</strong>ce it has a similar pharmacologic mechanism<br />

as clomipram<strong>in</strong>e, and the added advantage<br />

<strong>of</strong> hav<strong>in</strong>g a more favorable side-effect<br />

pr<strong>of</strong>ile. This open-label study is the first treatment<br />

study to exam<strong>in</strong>e the efficacy <strong>of</strong> venlafax<strong>in</strong>e<br />

<strong>in</strong> the treatment <strong>of</strong> BDD.<br />

METHODS<br />

Subjects<br />

Seventeen adult outpatient subjects (20–50<br />

years <strong>of</strong> age [mean age: 29.7±8.4 years], two<br />

males, and 15 females) participated <strong>in</strong> this medi-<br />

cation trial; 11 completed treatment (two males,<br />

n<strong>in</strong>e females; age range: 20–50 years [mean<br />

age: 31.2±8.8 years]). Subjects were recruited by<br />

advertis<strong>in</strong>g and other media and by referral from<br />

outside cl<strong>in</strong>icians. This research was approved<br />

by the Mount S<strong>in</strong>ai School <strong>of</strong> Medic<strong>in</strong>e’s <strong>in</strong>stitutional<br />

review board and written <strong>in</strong>formed consent<br />

was obta<strong>in</strong>ed from all participants after the<br />

study procedure and possible side effects were<br />

expla<strong>in</strong>ed and prior to the psychiatric and psychological<br />

<strong>in</strong>terviews.<br />

All patients met criteria for Diagnostic and<br />

Statistical Manual <strong>of</strong> Mental <strong>Disorder</strong>s-Fourth<br />

Edition, Text Revision diagnosis <strong>of</strong> BDD or its<br />

delusional variant as determ<strong>in</strong>ed by a study<br />

psychiatrist and psychologist experienced <strong>in</strong><br />

diagnos<strong>in</strong>g BDD. The pre-admission screen<strong>in</strong>gs<br />

<strong>in</strong>cluded a psychiatric and medical evaluation<br />

by a board-certified or board-eligible psychiatrist<br />

and a diagnostic <strong>in</strong>terview by a licensed psychologist<br />

to determ<strong>in</strong>e whether the patients met<br />

<strong>in</strong>clusion and exclusion criteria.<br />

Exclusion criteria <strong>in</strong>cluded comorbid psychiatric<br />

diagnoses: schizophrenia, schizoaffective<br />

disorder, or any other psychotic disorder not<br />

attributable to delusional BDD; current or lifetime<br />

bipolar disorder; current or recent (past 2 months)<br />

substance abuse or dependence; or recent suicide<br />

attempt or suicidal ideation that warranted<br />

consideration <strong>of</strong> hospitalization. Patients could<br />

not have used a psychotropic medication for the<br />

treatment <strong>of</strong> BDD (SSRI nor SNRI) with<strong>in</strong> 2 weeks<br />

<strong>of</strong> start <strong>of</strong> the trial (6 weeks for fluoxet<strong>in</strong>e). Of<br />

the 17 subjects, 7 were SSRI naïve and 10 had<br />

prior failed SSRI trials; one subject had tried only<br />

one SSRI (paroxet<strong>in</strong>e) and the rest had from two<br />

to four different prior SSRI trials (an average <strong>of</strong><br />

2.6 prior trials), many, though not all, <strong>of</strong> the trials<br />

would be considered adequate, while the rest<br />

were discont<strong>in</strong>ued due to adverse side effects.<br />

Patients were also excluded if they had any significant,<br />

unstable medical problems as were females<br />

who were pregnant, breast feed<strong>in</strong>g, or not us<strong>in</strong>g<br />

adequate contraception.<br />

Procedure<br />

Patients who met <strong>in</strong>clusion and exclusion<br />

criteria were entered <strong>in</strong>to a 12–16 week openlabel<br />

trial <strong>of</strong> venlafax<strong>in</strong>e. Patients were cont<strong>in</strong>ued<br />

past 12 weeks and up to 16 weeks if they<br />

had not been on a m<strong>in</strong>imally adequate (150 mg/<br />

Orig<strong>in</strong>al Research<br />

day) dose for 8 weeks; all patients had been on<br />

the adequate dose for 8 weeks by the 16-week<br />

po<strong>in</strong>t. Both a psychiatrist and a psychologist<br />

adm<strong>in</strong>istered key basel<strong>in</strong>e rat<strong>in</strong>gs, <strong>in</strong>clud<strong>in</strong>g<br />

the Cl<strong>in</strong>ical Global Impressions-Severity scale<br />

(CGI-S), 32 Yale-Brown Obsessive-Compulsive<br />

Scale Modified for <strong>Body</strong> <strong>Dysmorphic</strong> <strong>Disorder</strong><br />

(BDD-YBOCS), 33 Brown Assessment <strong>of</strong> Beliefs<br />

Scale, 34 Overvalued Idea Scale, 35 and the<br />

Schneier Disability Scale. 36 In addition, subjects<br />

completed the self-report version <strong>of</strong> the <strong>Body</strong><br />

<strong>Dysmorphic</strong> <strong>Disorder</strong> Exam<strong>in</strong>ation (BDDE-SR), 37<br />

the Beck Depression Inventory II (BDI-II), 38,39 and<br />

the Beck <strong>An</strong>xiety Inventory (BAI). 40<br />

Subjects met with their study psychiatrist<br />

every other week for the first 4 weeks and<br />

monthly thereafter for medication management<br />

and rat<strong>in</strong>gs. Dur<strong>in</strong>g each visit, the study<br />

psychiatrist adm<strong>in</strong>istered the Cl<strong>in</strong>ical Global<br />

Impressions-Improvement scale (CGI-I) and<br />

BDD-YBOCS, asked about side effects <strong>of</strong> the<br />

medication s<strong>in</strong>ce the last visit, and provided<br />

venlafax<strong>in</strong>e. Patients were started at a dose <strong>of</strong><br />

37.5 mg/day and <strong>in</strong>creased to a m<strong>in</strong>imum <strong>of</strong> 150<br />

mg/day, generally over the first 4 weeks <strong>of</strong> the<br />

study, and then ma<strong>in</strong>ta<strong>in</strong>ed at that dose for 8<br />

weeks. Dosage and titration were tailored to<br />

each <strong>in</strong>dividual subject’s current BDD symptoms<br />

and medication side effects. The actual range<br />

<strong>of</strong> f<strong>in</strong>al doses for the completers was 150–225<br />

mg/day with a mean f<strong>in</strong>al dose <strong>of</strong> 164±30.34 mg/<br />

day. Patients completed the study <strong>in</strong> an average<br />

<strong>of</strong> 13±1.70 weeks. At the study endpo<strong>in</strong>t, the<br />

psychiatrist and psychologist each repeated the<br />

basel<strong>in</strong>e measures, <strong>in</strong>clud<strong>in</strong>g the CGI-I rather<br />

than the CGI-S, and the patient completed the<br />

BDDE-SR, BAI, and BDI-II.<br />

Statistics<br />

For most measures, pre-post analyses were<br />

done us<strong>in</strong>g paired t-tests compar<strong>in</strong>g basel<strong>in</strong>e<br />

rat<strong>in</strong>gs with endpo<strong>in</strong>t rat<strong>in</strong>gs. In the case <strong>of</strong> the<br />

CGI-I, a s<strong>in</strong>gle sample t-test was conducted compar<strong>in</strong>g<br />

the endpo<strong>in</strong>t rat<strong>in</strong>gs with no change (a<br />

rat<strong>in</strong>g <strong>of</strong> 4). The key evaluative measures were<br />

the BDD-YBOCS and CGI-I rat<strong>in</strong>gs by the treat<strong>in</strong>g<br />

psychiatrist. For the key measures, data was<br />

analyzed for both completers and for the <strong>in</strong>tentto-treat<br />

sample with the last observations carried<br />

forward. Pearson correlations were used to<br />

exam<strong>in</strong>e relationships between variables.<br />

RESULTS<br />

<strong>Venlafax<strong>in</strong>e</strong> was found to be effective <strong>in</strong> lessen<strong>in</strong>g<br />

the global BDD severity and specific BDD<br />

symptoms <strong>of</strong> the 11 completers. (See the Table<br />

for a summary <strong>of</strong> key measures.) There was a<br />

significant decrease <strong>in</strong> overall BDD severity as<br />

measured by the CGI-I rat<strong>in</strong>gs completed by the<br />

treat<strong>in</strong>g psychiatrist and the study psychologist.<br />

Orig<strong>in</strong>al Research<br />

BDD symptoms were reduced significantly based<br />

on both the psychiatrist’s and the psychologist’s<br />

rat<strong>in</strong>gs on the BDD-YBOCS overall, as well as<br />

the compulsions subscale. Obsessions were<br />

reduced significantly based on the psychiatrist’s<br />

BDD-YBOCS rat<strong>in</strong>gs but did not quite reach significance<br />

based on the psychologist’s rat<strong>in</strong>gs.<br />

The f<strong>in</strong>d<strong>in</strong>gs were equally strong for the <strong>in</strong>tent-<br />

by the treat<strong>in</strong>g psychiatrist also showed significant<br />

improvement on the key outcome variables:<br />

the CGI-I (t=3.634, df=10, P=.005) and total BDD-<br />

YBOCS scores (t=2.985, df=10, P=.014). The Figure<br />

shows the change over time <strong>in</strong> the rat<strong>in</strong>gs by the<br />

psychiatrist. As <strong>in</strong>dicated, the rat<strong>in</strong>gs for both the<br />

CGI-I and the BDD-YBOCS are significantly different<br />

from basel<strong>in</strong>e by week 4.<br />

Based on the treat<strong>in</strong>g psychiatrists’ rat<strong>in</strong>gs, seven<br />

<strong>of</strong> 11 patients responded by hav<strong>in</strong>g a CGI-I rat<strong>in</strong>g <strong>of</strong><br />

1 or 2 (four <strong>of</strong> 11 patients), <strong>in</strong>dicat<strong>in</strong>g “very much”<br />

or “much improved,” respectively, or a BDD-YBOCS<br />

reduction <strong>of</strong> >33% (five <strong>of</strong> 11 patients).<br />

<strong>Venlafax<strong>in</strong>e</strong> may have improved <strong>in</strong>sight <strong>in</strong> BDD<br />

patients when measured by the Overvalued Idea<br />

Scale; although the psychiatrist’s rat<strong>in</strong>gs <strong>of</strong> <strong>in</strong>sight<br />

did not show a significant improvement after treatment,<br />

there was a trend <strong>in</strong> that direction and there<br />

was significant improvement based on the psychologists’<br />

rat<strong>in</strong>gs. This trend was not found for<br />

the Brown Assessment <strong>of</strong> Beliefs Scale or for the<br />

<strong>in</strong>sight question on the BDD-YBOCS (psychiatrist:<br />

t=1.00, df=10, P=.341; psychologist: t=–.90, df=10,<br />

P=.391). Change on the Schneier Disability Scale<br />

also varied by rater. The rat<strong>in</strong>gs by the psychiatrist<br />

did not show significant improvement but those by<br />

the psychologist did show significant improvement<br />

(psychiatrist: t=–1.12, df=10, P=.289;<br />

DISCUSSION<br />

<strong>Venlafax<strong>in</strong>e</strong> was effective <strong>in</strong> reduc<strong>in</strong>g the<br />

general and specific symptoms <strong>of</strong> BDD. The<br />

results were found for both compulsions and<br />

obsessions. The response was relatively robust<br />

with seven <strong>of</strong> the 11 completers (64%) rated as<br />

responders with four rated as “much” or “very<br />

much improved” and five hav<strong>in</strong>g a BDD-YBOCS<br />

score reduction <strong>of</strong> >33%.<br />

These results are generally consistent with<br />

the f<strong>in</strong>d<strong>in</strong>gs for venlafax<strong>in</strong>e <strong>in</strong> OCD. Additional<br />

research is needed <strong>in</strong> both disorders to clarify<br />

the possible advantages <strong>of</strong> SNRIs versus SSRIs.<br />

The improvement was found as early as 4 weeks<br />

and was found even with relatively moderate<br />

doses <strong>of</strong> venlafax<strong>in</strong>e. These are both notable f<strong>in</strong>d<strong>in</strong>gs<br />

given that the assumption, supported by most<br />

<strong>of</strong> the exist<strong>in</strong>g literature, is that SSRI treatment<br />

<strong>of</strong> BDD requires high doses and a relatively long<br />

trial. The current f<strong>in</strong>d<strong>in</strong>gs are, however, consistent<br />

with the f<strong>in</strong>d<strong>in</strong>gs for clomipram<strong>in</strong>e 16 : we found clomipram<strong>in</strong>e<br />

to be significantly more effective than<br />

desipram<strong>in</strong>e at a mean dose <strong>of</strong> 138±87 mg/day<br />

(the mean dose <strong>of</strong> desipram<strong>in</strong>e was 147±80 mg/<br />

day); the clomipram<strong>in</strong>e dose is comparable with or<br />

slightly lower than the mean dose <strong>of</strong> venlafax<strong>in</strong>e<br />

used <strong>in</strong> the current study. A reanalysis <strong>of</strong> the data<br />

shows that the effect <strong>in</strong> the clomipram<strong>in</strong>e versus<br />

desipram<strong>in</strong>e study was approach<strong>in</strong>g significance<br />

at 4 weeks for both the BDD-YBOCS (t=2.01, df=20,<br />

P=.058) and the CGI-I (t=1.87, df=21, P=.075). Our<br />

current f<strong>in</strong>d<strong>in</strong>gs are also consistent with a recent<br />

open-label citalopram trial that found significant<br />

improvement at 4.6±2.6 weeks, which preceded<br />

the <strong>in</strong>crease <strong>in</strong> dose to 60 mg/day. 14<br />

<strong>Venlafax<strong>in</strong>e</strong> also seems to improve the general<br />

distress felt by BDD patients as shown by<br />

the change <strong>in</strong> those measures on the BDDE-SR.<br />

Other aspects <strong>of</strong> BDD symptoms measured by<br />

this <strong>in</strong>strument were not found to change significantly<br />

though it is not clear whether this was<br />

due to <strong>in</strong>sensitivity <strong>of</strong> the <strong>in</strong>strument, a lack <strong>of</strong><br />

change <strong>in</strong> the behaviors that are asked about,<br />

or the small sample size. Likewise, there was<br />

no change <strong>in</strong> function<strong>in</strong>g as measured by the<br />

Schneier Disability Scale.<br />

Evidence for a change <strong>in</strong> <strong>in</strong>sight was weak<br />

and further research is required to clarify the<br />

efficacy <strong>of</strong> venlafax<strong>in</strong>e <strong>in</strong> improv<strong>in</strong>g <strong>in</strong>sight and<br />

relationship between <strong>in</strong>sight and response to<br />

venlafax<strong>in</strong>e. Past research has suggested that<br />

Orig<strong>in</strong>al Research<br />

SSRIs <strong>in</strong> BDD are as effective <strong>in</strong> patients with<br />

poor <strong>in</strong>sight as with good <strong>in</strong>sight 16,17 and may<br />

actually improve <strong>in</strong>sight. 14,16<br />

The primary limitations <strong>of</strong> this study are the<br />

small sample size (n=17, 11 completers), the<br />

open-label design, and the primarily female sample.<br />

Most <strong>of</strong> the patients <strong>in</strong> this study received<br />

only venlafax<strong>in</strong>e 150 mg/day, which was what<br />

we established as our m<strong>in</strong>imally acceptable dose<br />

because it is considered the m<strong>in</strong>imal adequate<br />

dose <strong>in</strong> OCD. We would expect higher doses to<br />

be more effective <strong>in</strong> BDD as <strong>in</strong> OCD. However,<br />

even this relatively low dose was effective <strong>in</strong><br />

these patients.<br />

CONCLUSION<br />

<strong>Venlafax<strong>in</strong>e</strong> may be an effective treatment<br />

for BDD, <strong>in</strong>clud<strong>in</strong>g both obsessive and compulsive<br />

symptoms, even at relatively low doses.<br />

Further research should be conducted us<strong>in</strong>g a<br />
