199—PREVALENCE OF COMORBIDI-<br />

TIES IN DVT AND PE PATIENTS. Yin H,<br />

University <strong>of</strong> Illinois at Chicago, Vogenberg R, Aon<br />

Consulting. E-mail: hyin3@uic.edu<br />

Objective: Deep vein thrombosis (DVT) and pulmonary<br />

embolism (PE) patients tend to have multiple<br />

comorbidities that need to be considered when<br />

evaluating pharmacotherapy outcomes. DVT<br />

patients may have different comorbidities from PE<br />

patients, and until now this comparison had not been<br />

examined in the literature. This study aims to identify<br />

the prevalence <strong>of</strong> comorbidities in DVT and PE<br />

patients and to compare comorbidity prevalence <strong>of</strong><br />

the DVT group to that <strong>of</strong> the PE group.<br />

Methods: The study is based on an administrative<br />

database from eight U.S. hospitals. There are<br />

2,506 DVT patients and 1,973 PE patients’ records<br />

in the pooled database. Patients with both DVT and<br />

PE were considered only as PE patient in the analysis.<br />

Comorbidities were categorized and summarized<br />

according to ICD-9-CM codes. A comorbidity<br />

was included in the analysis only when prevalence<br />

in DVT or PE group was greater than 1%. A chisquare<br />

test was performed to analyze whether the<br />

comorbidity burdens were similar or different<br />

between the two groups.<br />

Results: There are 29 comorbidities with prevalence<br />

greater than 1% in either DVT or PE group.<br />

DVT patients are found to be more likely to have<br />

peripheral vascular disease, anemia, cerebrovascular<br />

disease, and renal disease. PE patients are more<br />

likely to have cardiac arrhythmias, congestive heart<br />

failure, mild to moderate diabetes, chronic pulmonary<br />

disease, and cases <strong>of</strong> drug abuse. Further, a<br />

PE patient tends to have more comorbidities overall<br />

compared with a DVT patient.<br />

Conclusions: Prevalence <strong>of</strong> comorbidities differs<br />

between DVT and PE patients. Additional study is<br />

needed to address the reasons why PE patients are<br />

more likely to have certain comorbidities. DVT<br />

patients who have these comorbidities should be<br />

identified in effort to prevent PE development<br />

through pharmacotherapy prophylaxis.<br />

Objective: To evaluate the analgesic efficacy and<br />

safety <strong>of</strong> a single, preoperative, epidural injection <strong>of</strong><br />

sustained-release morphine (DepoMorphine) compared<br />

with standard preservative-free morphine sulfate<br />

(MS) in patients undergoing total hip arthroplasty<br />

with intrathecal anesthesia.<br />

Methods: A prospective, open-label, serial<br />

cohort, dose-ranging trial at six U.S. sites enrolled<br />

39 patients scheduled for total hip arthroplasty with<br />

intrathecal anesthesia. Patients were assigned to<br />

receive DepoMorphine 10 (N = 4), 15 (N = 1), 20<br />

(N = 12), 25 (N = 1), or 30 mg (N = 8) or a control<br />

<strong>of</strong> MS 5 mg (N = 13) as a single injection via epidural<br />

catheter 30 minutes preoperatively. Regional<br />

anesthesia was then administered with an intrathecal<br />

injection <strong>of</strong> bupivacaine (12.5–17.5 mg). Patients<br />

had postoperative access to intravenous patient-controlled<br />

analgesia using fentanyl for treatment <strong>of</strong><br />

breakthrough pain. Efficacy parameters were total<br />

fentanyl consumption, time to first fentanyl use,<br />

pain intensity rated by 100 mm visual analog<br />

(VAS), and 4-term categorical (CAT) scales. Safety<br />

was evaluated through clinical assessments and laboratory<br />

testing.<br />

Results: Mean total fentanyl use for<br />

DepoMorphine 10, 20, and 30 mg groups were 598<br />

± 230 mcg, 261 ± 95 mcg, and 143 ± 101 mcg,<br />

respectively, and 1,095 ± 280 mcg for MS (P = .01).<br />

Median times to first fentanyl dose were 18, 36, and<br />

35 hours for DepoMorphine 10, 20, and 30 mg,<br />

respectively, and 6 hours for MS (P < .001). VAS<br />

and CAT scores were comparable among all groups.<br />

Pain medication was rated “excellent” by 46% <strong>of</strong><br />

DepoMorphine-treated patients and 15% <strong>of</strong> MStreated<br />

patients. The most common postoperative<br />

adverse effects for both groups were pruritus, fever,<br />

and nausea; respiratory effects were mild to moderate<br />

in severity and similar for both groups.<br />

Conclusions: DepoMorphine provided prolonged<br />

dose-dependent postoperative analgesia versus<br />

MS 5 mg in patients undergoing total hip arthroplasty<br />

with intrathecal anesthesia. This new treatment<br />

modality <strong>of</strong>fers clinicians a new option that<br />

may simplify postoperative pain management.<br />

Objective: Rationale: Complications can arise<br />

from epidural catheterization, especially when anticoagulants<br />

are administered. A new, sustainedrelease<br />

morphine (DepoMorphine [DM]) may obviate<br />

the need for an indwelling epidural catheter and<br />

provide prolonged analgesia. Objective: To compare<br />

analgesic efficacy and safety <strong>of</strong> four dosage<br />

strengths <strong>of</strong> DM with a single dose <strong>of</strong> DM 5 mg<br />

(dose-control) and with standard epidural morphine<br />

sulfate (MS) 5 mg after elective low abdominal<br />

surgery.<br />

Methods: 519 adults were randomly assigned to<br />

receive preoperative epidural injection <strong>of</strong> MS 5 mg<br />

or DM 5, 10, 15, 20, or 25 mg. Patients had patientcontrolled<br />

analgesia (PCA) using intravenous fentanyl<br />

for postoperative pain control. Fentanyl consumption<br />

through 48 hours was the primary efficacy<br />

endpoint. Pain intensity (VAS: 0–100 mm) and<br />

overall pain control (very good, good, fair, or poor)<br />

were also assessed. Adverse events were recorded.<br />

Results: Mean (± SD) total fentanyl use through<br />

48 hours decreased from 995.1 ± 987.0 mcg to<br />

682.5 ± 620.0 mcg, respectively, with DM 10 and<br />

25 mg compared with 1,213.3 ± 1079 mcg and<br />

1217.1 ± 894.0 mcg, respectively, with DM 5 mg<br />

and MS 5 mg (P< .05). In the DM 10, 15, 20, and 25<br />

mg groups, 15% <strong>of</strong> patients required no supplemental<br />

fentanyl through 48 hours compared with 6%<br />

and 2%, respectively, in DM 5 mg and MS 5 mg<br />

groups (P < .01). VAS scores were better with DM<br />

for 48 hours postdose. On Day 2, pain control was<br />

rated significantly better in the 15 and 25 mg DM<br />

groups versus the MS group (P < .05). Urinary<br />

retention and pruritus occurred more frequently in<br />

DM patients (9% versus 3% and 54% versus 39%,<br />

respectively; P < .05); other adverse events were<br />

similar across groups.<br />

Conclusions: A single epidural injection <strong>of</strong> DM<br />

provides prolonged postoperative analgesia,<br />

improved pain control, and decreased need for postoperative<br />

PCA fentanyl, thereby simplifying postoperative<br />

pain treatment.<br />

Objective: Weight gain during long-term antidepressant<br />

treatment is a common concern and may<br />

interfere with compliance with pharmacotherapy.<br />

Methods: Data were pooled from two doubleblind<br />

studies. Patients received placebo (N = 192),<br />

duloxetine 80 mg/day (40 mg BID; N = 188), duloxetine<br />

120 mg/day (60 mg BID; N = 196), or paroxetine<br />

20 mg QD (N = 183) for 8 weeks. Acute treatment<br />

responders (≥ 30% reduction from baseline<br />

HAMD17 total score) continued double-blind therapy<br />

for an additional 26 weeks. Data from a 52-<br />

week open-label study <strong>of</strong> duloxetine 80–120<br />

mg/day (40–60 mg BID; N = 1,279) were analyzed<br />

separately.<br />

Results: Following acute treatment, mean<br />

changes in weight for patients receiving duloxetine<br />

80 mg/day (–0.2 kg), duloxetine 120 mg/day (–0.2<br />

kg), or paroxetine 20 mg QD (–0.1 kg) did not differ<br />

significantly from placebo (0.1 kg). After 34<br />

weeks, mean weight changes for duloxetine (80<br />

mg/day: 0.8 kg; 120 mg/day: 1.0 kg) did not differ<br />

significantly from placebo (0.1 kg), while patients<br />

receiving paroxetine 20 mg QD had a mean weight<br />

change significantly greater than the placebo group<br />

(1.2 kg; P = .020). Incidences <strong>of</strong> weight gain ≥ 7%<br />

during the 34-week study were: placebo (3.0%),<br />

duloxetine 80 mg/day (3.2%), duloxetine 120<br />

mg/day (8.8%), and paroxetine 20 mg QD (11.5%).<br />

In the open-label study, mean changes in weight at<br />

weeks 8, 32 and 52 were –.2 kg, 1.5 kg, and 2.1 kg,<br />

respectively.<br />

Conclusions: In these studies, changes in body<br />
