  • Change From Randomization to End of Treatment in Scores on the Hamilton Anxiety Rating Scale (HAM-A) [ Time Frame: baseline and 7 weeks ]
    The HAM-A is administered by an interviewer who asks a series of questions related to symptoms of anxiety. The interviewer then rates the individual on a five-point scale for each of the 14 items. Seven of the items specifically address psychic anxiety and the remaining seven items address somatic anxiety. The total anxiety score ranges from 0 to 56, lower scores are better. Change from randomization to end of treatment in scores on the Hamilton Anxiety Rating Scale (HAM-A)is measured.
  • Changes From Randomization to End of Treatment in Scores on the Beck Depression Inventory [ Time Frame: baseline and 7 weeks ]
    Scoring The BDI consist of twenty-one questions about how the subject has been feeling in the last week. Each question has a set of at least four possible answer choices, ranging in intensity as follows: (0) I do not feel sad.
    1. I feel sad.
    2. I am sad all the time and I can't snap out of it.
    3. I am so sad or unhappy that I can't stand it.
    A value of 0 to 3 is assigned for each answer and the total score is compared to a key to determine the depression's severity. The standard cut-offs are as follows:[6] 0-9: indicates minimal depression 10-18: indicates mild depression 19-29: indicates moderate depression 30-63: indicates severe depression. Higher total scores indicate more severe depressive symptoms.

  • Change From Randomization to End of Treatment in Scores for the Clinical Global Impression(CGI-S and CGI-I) [ Time Frame: baseline and 7 weeks ]
    Scale for scoring: Clinical Global Impression(CGI-S)
    1. = Normal, no symptoms
    2. = Borderline ill
    3. = Mildly ill
    4. = Moderately ill
    5. = Markedly ill
    6. = Severely ill
    7. = Most extremely ill
    Clinical Global Impression(CGI-I)-improvement since treatment
    1. very much improved
    2. much improved
    3. minimally improved
    4. no change from baseline
    5. minimally worse
    6. much worse
    7. very much worse
  • Change From Randomization to End of Treatment for Trail Making Tet (TMT) [ Time Frame: baseline to 7 weeks ]
    Trail Making Test (TMT)Results for TMT are reported as the number of seconds required to complete the task. Higher scores reveal greater impairment. Average =29 seconds, Deficient > 78 seconds
  • Changes From Randomization to End of Treatment in Scores on the Mini Mental State Examination (MMSE) [ Time Frame: baseline and 7 weeks ]
    Mini Mental State Examination (MMSE),a low score less than or equal to 23 indicates cognitive impairment and the need for further evaluation; normal cognitive function = 27-30, mild cognitive impairment = 21-26, moderate cognitive impairment = 11-20, and severe cognitive impairment = 0-10. The highest possible score is 30.
  • Changes From Randomization to End of Treatment in Scores on the Sheehan Disability Scores (SDS) [ Time Frame: baseline and 7 weeks ]
    Scoring: Participants rate the extent to which work, social life, and home life are impaired by his or her symptoms. A 10 point scale is used where 0= not impaired and 10 is highly impaired indicating. The three aspects of life can be summed up into a single dimensional measure of global functional impairment that indicates 0= not impaired and 30 = highly impaired. Scores of 5 or greater are on any of the three scales are considered significant.

Treatment Effects of Escitalopram (Lexapro®) on Generalized Anxiety Disorder in Patients With HIV and AIDS
Treatment Effects of Escitalopram (Lexapro®) on Generalized Anxiety Disorder, Adherence to Antiretroviral Therapy,Cognition, and Immune Status Among Patients With HIV and AIDS: A 6-week Open-label, Prospective, Pilot Trial.
The purpose of this study is to evaluate whether escitalopram is safe, well tolerated, and effective in the treatment of HIV-infected patients with generalized anxiety disorder.
Anxiety disorders are twice as prevalent among HIV-infected patients as they are in the general population. Approximately 25%-40% of HIV-infected patients have anxiety disorders; Generalized Anxiety Disorder, Panic disorder and post-traumatic Stress Disorder being the most frequent. Non-adherence to anti-retroviral medications is commonly seen in patients with HIV with GAD.The role of specific selective serotonin reuptake (SSRIs) in the treatment of HIV-patients with GAD is unclear. Escitalopram has been used in the treatment of GAD in the general population. It has been shown to be safe in HIV-patients with a tolerable side-effect profile. However, whether it can improve GAD in HIV-infected patients has not yet been investigated.
Phase 3
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
  • Anxiety Disorders
  • HIV Infections
Drug: Escitalopram
10-20 mg/day oral of Escitalopram for 6-weeks. Escitalopram flexible dose (10-20 mg/day). A forced escalation schedule of escitalopram was used to titrate it to the maximum tolerated dose. Drug was discontinued at the end of the study.
Experimental: Escitalopram
Treatment effects of Escitalopram in Generalized Anxiety Disorder in patients with HIV/AIDS.Open label, rater-blinded, prospective, 6-week trial of escitalopram.Subjects received escitalopram 10-20mg. Escitalopram was started at 10mg per day and augmented weekly in 10mg per day increments, the maximum dose being 20mg per day.
Intervention: Drug: Escitalopram
