Context Antidepressant-associated sexual dysfunction is a common adverse effect that frequently results in premature medication treatment discontinuation and for which no treatment has demonstrated efficacy in women.
Objective To evaluate the efficacy of sildenafil for sexual dysfunction associated with selective and nonselective serotonin reuptake inhibitors (SRIs) in women.
Design, Setting, and Participants An 8-week prospective, parallel-group, randomized, double-blind, placebo-controlled clinical trial conducted between September 1, 2003, and January 1, 2007, at 7 US research centers that included 98 previously sexually functioning, premenopausal women (mean [SD] age 37.1 [6] years) whose major depression was remitted by SRIs but who were also experiencing sexual dysfunction.
Intervention Forty-nine patients were randomly assigned to take sildenafil or placebo at a flexible dose starting at 50 mg adjustable to 100 mg before sexual activity.
Main Outcome Measures The primary outcome measure was the mean difference in change from baseline to study end (ie, lower ordinal score) on the Clinical Global Impression sexual function scale. Secondary measures included the Female Sexual Function Questionnaire, the Arizona Sexual Experience scale-female version, the University of New Mexico Sexual Function Inventory-female version, a sexual activity event log, and the Hamilton Depression Rating scale. Hormone levels were also assessed.
Results In an intention-to-treat analysis, women treated with sildenafil had a mean Clinical Global Impression–sexual function score of 1.9 (95% confidence interval [CI], 1.6-2.3) compared with those taking placebo (1.1; 95% CI, 0.8-1.5), with a mean end point difference of 0.8 (95% CI, 0.6-1.0; P = .001). Assigning baseline values carried forward to the 22% of patients who prematurely discontinued resulted in a mean end point in the sexual function score of 1.5 (95% CI, 1.1-1.9) among women taking sildenafil compared with 0.9 (95% CI, 0.6-1.3) among women taking placebo with a mean end point difference of 0.6 (95% CI, 0.3-0.8; P = .03). Baseline endocrine levels were within normal limits and did not differ between groups. The mean (SD) Hamilton scores for depression remained consistent with remission in both groups (4.0 [3.6]; P = .90). Headache, flushing, and dyspepsia were reported frequently during treatment, but no patients withdrew because of serious adverse effects.
Conclusion In this study population, sildenafil treatment of sexual dysfunction in women taking SRIs was associated with a reduction in adverse sexual effects.

Context Foreign-born persons accounted for 57% of all tuberculosis (TB) cases in the United States in 2006. Current TB control strategies have not sufficiently addressed the high levels of TB disease and latent TB infection in this population.
Objective To determine the risk of TB disease and drug-resistant TB among foreign-born populations and the potential impact of adding TB culture to overseas screening procedures for foreign-born persons entering the United States.
Design, Setting, and Participants Descriptive epidemiologic analysis of foreign-born persons in the United States diagnosed with TB from 2001 through 2006.
Main Outcome Measures TB case rates, stratified by time since US entry, country of origin, and age at US entry; anti-TB drug-resistance patterns; and characteristics of TB cases diagnosed within 3 months of US entry.
Results A total of 46 970 cases of TB disease were reported among foreign-born persons in the United States from 2001 through 2006, of which 12 928 (28%) were among recent entrants (within 2 years of US entry). Among the foreign-born population overall, TB case rates declined with increasing time since US entry, but remained higher than among US-born persons—even more than 20 years after arrival. In total, 53% of TB cases among foreign-born persons occurred among the 22% of the foreign-born population born in sub-Saharan Africa and Southeast Asia. Isoniazid resistance was as high as 20% among recent entrants from Vietnam and 18% for recent entrants from Peru. On average, 250 individuals per year were diagnosed with smear-negative, culture-positive TB disease within 3 months of US entry; 46% of these were from the Philippines or Vietnam.
Conclusion The relative yield of finding and treating latent TB infection is particularly high among individuals from most countries of sub-Saharan Africa and Southeast Asia.
Context Cytomegalovirus (CMV) infection is associated with adverse clinical outcomes in immunosuppressed persons, but the incidence and association of CMV reactivation with adverse outcomes in critically ill persons lacking evidence of immunosuppression have not been well defined.
Objective To determine the association of CMV reactivation with intensive care unit (ICU) and hospital length of stay in critically ill immunocompetent persons.
Design, Setting, and Participants We prospectively assessed CMV plasma DNAemia by thrice-weekly real-time polymerase chain reaction (PCR) and clinical outcomes in a cohort of 120 CMV-seropositive, immunocompetent adults admitted to 1 of 6 ICUs at 2 separate hospitals at a large US tertiary care academic medical center between 2004 and 2006. Clinical measurements were assessed by personnel blinded to CMV PCR results. Risk factors for CMV reactivation and association with hospital and ICU length of stay were assessed by multivariable logistic regression and proportional odds models.
Main Outcome Measures Association of CMV reactivation with prolonged hospital length of stay or death.
Results The primary composite end point of continued hospitalization (n = 35) or death (n = 10) by 30 days occurred in 45 (35%) of the 120 patients. Cytomegalovirus viremia at any level occurred in 33% (39/120; 95% confidence interval [CI], 24%-41%) at a median of 12 days (range, 3-57 days) and CMV viremia greater than 1000 copies/mL occurred in 20% (24/120; 95% CI, 13%-28%) at a median of 26 days (range, 9-56 days). By logistic regression, CMV infection at any level (adjusted odds ratio [OR], 4.3; 95% CI, 1.6-11.9; P = .005) and at greater than 1000 copies/mL (adjusted OR, 13.9; 95% CI, 3.2-60; P < .001) and the average CMV area under the curve (AUC) in log10 copies per milliliter (adjusted OR, 2.1; 95% CI, 1.3-3.2; P < .001) were independently associated with hospitalization or death by 30 days. In multivariable partial proportional odds models, both CMV 7-day moving average (OR, 5.1; 95% CI, 2.9-9.1; P < .001) and CMV AUC (OR, 3.2; 95% CI, 2.1-4.7; P < .001) were independently associated with a hospital length of stay of at least 14 days.
Conclusions These preliminary findings suggest that reactivation of CMV occurs frequently in critically ill immunocompetent patients and is associated with prolonged hospitalization or death. A controlled trial of CMV prophylaxis in this setting is warranted.
Tuberculosis (TB) and the emerging multidrug-resistant TB epidemic represent major challenges to human immunodeficiency virus (HIV) care and treatment programs in resource-limited settings. Tuberculosis is a major cause of mortality among patients with HIV and poses a risk throughout the course of HIV disease, even after successful initiation of antiretroviral therapy (ART). Progress in the implementation of activities directed at reducing TB burden in the HIV population lags far behind global targets. HIV programs designed for longitudinal care are ideally suited to implement TB control measures and have no option but to address TB vigorously to save patient lives, to safeguard the massive investment in HIV treatment, and to curb the global TB burden. We propose a framework of strategic actions for HIV care programs to optimally integrate TB into their services. The core activities of this framework include intensified TB case finding, treatment of TB, isoniazid preventive treatment, infection control, administration of ART, TB recording and reporting, and joint efforts of HIV and TB programs at the national and local levels.
