Doxycycline compared with benzathine penicillin for the treatment of early syphilis.

BACKGROUND: Doxycycline is the preferred recommended second-line agent for the treatment of syphilis, although efficacy data from controlled trials are lacking. We compared the serological responses of patients with early syphilis treated with doxycycline with the responses of patients treated with benzathine penicillin G (BPG). METHODS: All patients who received a diagnosis of early syphilis attending 2 public sexually transmitted disease clinics in Baltimore, Maryland, who were treated with doxycycline (100 mg orally, twice daily for 14 days) between October 1993 and June 2000 were eligible. Patients treated with BPG (a single dose of 2.4 million units intramuscularly) were selected as the control group. Inclusion criteria included a clinician-recorded diagnosis of primary, secondary, or early latent syphilis with reactive serological test results at the time of diagnosis and at least 1 follow-up serological test titer. Serological failure was defined as lack of a 4-fold drop in rapid plasma reagin titer 270-400 days after treatment, or a 4-fold increase in titer 30-400 days after therapy. RESULTS: During the study period, 1558 patients were treated for early syphilis, and 87 received doxycycline. Of those treated with doxycycline, 34 met the inclusion criteria. Seventy-three patients from a randomly selected group of 200 age-matched individuals treated with BPG met the inclusion criteria. There were 4 patients with serological failure in the BPG group (5.5%; 95% confidence interval [CI], 1.6%-13.8%) and 0 patients with serological failure in the doxycycline group (0%; 95% CI, 0%-10.3%; P=.2). The median times to successful serological responses for patients in the doxycycline and BPG groups were 106 days (95% CI, 75-149 days) and 137 days (95% CI, 111-172 days), respectively (P=.6). CONCLUSION: Doxycycline appears to be an effective agent for the treatment of early syphilis.

Cost-effectiveness of screening strategies for Gonorrhea among females in private sector care.

OBJECTIVE: To identify the optimal screening algorithm for gonorrhea infection among females in private sector care, using cost-effectiveness analysis. METHODS: We compared 6 strategies using decision analysis for urine nucleic acid amplification testing for gonorrhea testing in a theoretical cohort of 10,000 females aged 15-35 years: 1) screen women aged younger than 25 years; 2) screen women aged younger than 30 years; 3) screen women aged younger than 25 years who report any risk (pregnant, drug use, new sexual partner < 30 days); 4) screen women aged younger than 30 years who report any risk; 5) screen women aged younger than 25 years or those who report any risk; and 6) screen women aged younger than 30 years or those who report any risk. Infection prevalence and sensitivity and specificity were by direct observation from a retrospective cohort of females attending the Baltimore City Sexually Transmitted Disease Clinics between 1999 and 2002. The main outcome measures were untreated gonorrhea cases and their sequelae in women, transmission to a male partner, congenital outcomes, and cost to prevent a case. RESULTS: Prevalence of gonorrhea was 3.0%. Not screening would result in 300 untreated cases. Not screening was cost-saving over all screening strategies. Strategy 6 resulted in the fewest cases of untreated infection (82), although Strategy 3 was the most cost-effective of the screening strategies. Univariate sensitivity analysis identified a threshold of 4.75% gonorrhea prevalence, more than which Strategy 3 became cost-saving over not screening. CONCLUSION: Screening is recommended for females aged younger than 25 years with specific risks in populations with a gonorrhea prevalence of 4.75% or greater. LEVEL OF EVIDENCE: II-2.

Gonorrhea reinfection among sexually transmitted disease clinic attendees in Baltimore, Maryland.

OBJECTIVES: We hypothesized that an active follow-up program to assess for reinfection after gonorrhea treatment could be a useful disease control strategy. GOAL: We evaluated an active follow-up and repeat testing program for all Baltimore sexually transmitted disease clinic patients diagnosed with gonorrhea. STUDY DESIGN: From September 2003 to May 2004, all clients with a treated gonorrhea infection were advised to return 3 months later for repeat testing. If clients did not return as scheduled, field outreach was attempted. At follow-up visits, urine was tested for gonorrhea and consenting participants completed a behavioral survey. In addition, we reviewed morbidity records for any intercurrent gonorrhea infections reported during the project period. RESULTS: Of the 667 participants diagnosed with gonorrhea at baseline, 54 had a gonorrhea reinfection diagnosed for an incidence of 13.8 per 100 person-years. One hundred seventy-eight (27%) either presented for a follow-up visit or were located through field efforts, and of these, 5 (2.8%) had gonorrhea detected on follow-up urine testing. No measured factors had predictive value in identifying gonorrhea reinfection. CONCLUSIONS: Although reinfection rates were high, we found that field staff intervention to increase follow-up testing rates did not identify a significant amount of repeat infections compared with passive surveillance.

Concurrent sexually transmitted infections (STIs) in sex partners of patients with selected STIs: implications for patient-delivered partner therapy.

BACKGROUND: Patient-delivered partner therapy (PDPT) is the practice of providing disease-specific antimicrobial agents to patients for delivery to their sex partners. Some partners who receive PDPT may forgo clinical evaluation, resulting in missed opportunities for the diagnosis and treatment of comorbid conditions. METHODS: We conducted a review of electronic charts for 8623 individuals attending 4 sexually transmitted disease clinics who were sex partners of patients with selected sexually transmitted infections (STIs). We evaluated the concordance between STIs diagnosed in partners and their reported exposures for which they might have received PDPT. RESULTS: Among 3503 female and 4647 heterosexual male partners, 19 (0.4%) of 4716 individuals tested were newly diagnosed with human immunodeficiency virus (HIV) infection, and 61 individuals (0.7%) had syphilis. Pelvic inflammatory disease was diagnosed in 133 women (3.8%). Seventy-two (3.2%) of 2226 female and heterosexual male partners reporting exposure to patients with chlamydial infection had gonorrhea diagnosed. Chlamydial infection or gonorrhea was diagnosed in 81 heterosexual male partners (10.3%) who reported contact with women with trichomoniasis. Among 473 men who have sex with men (MSM; including bisexual men), 13 (6.3%) of 207 tested were newly diagnosed with HIV infection, and 8 (1.7%) had syphilis. Six (6.1%) of 98 MSM reporting exposure to patients with chlamydial infection had gonorrhea diagnosed. CONCLUSIONS: Infrequent coinfections in female and heterosexual male partners exposed to patients with chlamydial infection or gonorrhea would not preclude use of PDPT. However, PDPT for male partners of women with trichomoniasis and for MSM requires further study.

Defining core gonorrhea transmission utilizing spatial data.

Spatial distribution of repeat and singly occurring gonorrhea in Baltimore, Maryland, was examined to identify clusters of core transmitters. Gonorrhea reported between 2001 and 2002 was geocoded and mapped. Those with more than one gonorrhea infection separated by more than 14 days during the 2-year period were considered repeaters. Other cases were treated as isolated events. Six definitions of core transmission were examined by census tracts with the highest quintiles of 1) cases for 2001, 2) cases for 2002, 3) rates for 2001, 4) rates for 2002, 5) counts of repeaters over the 2-year period, and 6) proportion of total cases that were repeaters. Of the 6,108 gonorrhea cases analyzed, 9% were repeaters. Repeaters were more likely to be female and younger. Core areas identified by definitions based on overall disease burden agreed well with each other but had poor agreement with definitions based upon repeat infections. Repeaters clustered to a greater extent at smaller distances than did singly occurring gonorrhea cases. Repeat gonorrhea infections are prevalent in Baltimore and likely represent behavior consistent with core transmission. Census tracts of core transmission defined by geographic distribution of repeat infections may indicate foci of highest risk sexual behaviors and high transmission.

The prevalence of psychiatric disorders in sexually transmitted disease clinic patients and their association with sexually transmitted disease risk.

BACKGROUND AND OBJECTIVES: Psychiatric disorders could limit the success of behavioral counseling strategies. We evaluated the prevalence of psychiatric disorders among sexually transmitted disease (STD) clinic patients and their association with STD risk. METHODS: A systematic sample of 201 patients presenting to a public STD clinic in Baltimore, Maryland, participated in the structured clinical interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. RESULTS: Overall, 45% of 201 STD clinic patients interviewed had a current axis I disorder and 29% had an axis II personality disorder. Substance use disorders predominated among axis I diagnoses; antisocial personality disorder (ASPD) predominated among axis II diagnoses, with an ASPD prevalence of 29.4% in men. ASPD was associated with a diagnosis of an STD (odds ratio, 3.67; 95% confidence interval, 1.63-8.30; P = 0.002). Substance use was not associated with an STD diagnosis. CONCLUSIONS: STD clinic patients have complex psychopathology that could increase HIV risk and compromise prevention interventions. Specialized counseling strategies, particularly targeting personality traits of ASPD, could improve prevention outcomes.

Depression and HIV risk behaviors among patients in a sexually transmitted disease clinic.

OBJECTIVE: The authors' goal was to investigate the relationship between depression and HIV risk behaviors or sexually transmitted disease (STD) diagnosis at an urban STD clinic. METHOD: Using audio computer-assisted self-interview, 671 STD clinic patients answered questions about HIV risk behaviors and depression in a large-scale, cross-sectional study. A subset of the patients (N=201) was evaluated for current major depressive disorder by interviewers using the nonpatient edition of the Structured Clinical Interview for DSM-IV. RESULTS: Depressed patients were more likely to have sex for money or drugs, to have had sex with an intravenous drug user, to have sex when "high" on alcohol or drugs, to have a greater number of lifetime sex partners, and to abuse alcohol or drugs than were nondepressed patients. Associations of HIV risk behaviors with depression persisted after adjustment for substance abuse. CONCLUSIONS: Depression in STD clinic patients is associated with HIV risk behaviors but not STD diagnosis. Identifying depression and developing strategies to intervene effectively may reduce HIV risk behaviors and improve health outcomes.

New sexually transmitted diseases in HIV-infected patients: markers for ongoing HIV transmission behavior.

OBJECTIVE: The objective of this study was to describe the rate of new sexually transmitted diseases (STDs) among HIV-infected patients and to define the behavioral and clinical characteristics of HIV-infected patients who return with a new STD in follow-up. DESIGN: The study design was a record-based clinical cohort study focusing on patients testing HIV-seropositive in the STD clinics of Baltimore, Maryland from 1993 to 1998. METHODS: The authors identified those HIV-infected patients later diagnosed with an STD in follow-up and compared their demographic, behavioral, and clinical characteristics with those who were not diagnosed with an STD in follow-up. RESULTS: Of 796 men and 354 women with HIV infection, 13.9% of men and 11.9% of women were diagnosed with an STD after their initial HIV diagnosis. HIV-infected men returned with a new STD at a rate of 7 cases per 100 person-years; HIV-infected women returned at a rate of 5.6 cases per 100 person-years. In men, multiple sex partners and sex worker contact were associated with a subsequent STD diagnosis (OR = 1.67, p =.037; OR = 1.82, p =.015, respectively). In women, age younger than 30 years was associated with the diagnosis of an STD after the diagnosis of HIV infection (OR = 2.94, p =.0009). CONCLUSIONS: Patients diagnosed with HIV in an STD clinic setting commonly return with new STDs in follow-up, suggesting continued exposure of HIV to others. More intensive screening and counseling interventions focused on STD prevention in those with HIV infection is a necessary HIV prevention strategy.

Trichomonas vaginalis polymerase chain reaction compared with standard diagnostic and therapeutic protocols for detection and treatment of vaginal trichomoniasis.

Wet preparation has limited sensitivity for diagnosis of Trichomonas vaginalis (TV) infection. An observational study of 337 women was conducted to evaluate a new polymerase chain reaction (PCR) test for TV. The sensitivities of wet preparation and TV culture were 52% (95% confidence interval [CI], 41-62) and 78% (95% CI, 69-86), respectively. TV PCR had a sensitivity of 84% (95% CI, 75-90) and a specificity of 94% (95% CI, 90-97). Metronidazole was provided to 67 (69%) of 97 women with TV because of TV on wet preparation, exposure to TV, or a diagnosis of bacterial vaginosis or pelvic inflammatory disease; however, if TV PCR had been used for diagnosis, 81 (84%) of 97 women with TV would have been treated (P=.02). TV is significantly undertreated using standard algorithms for metronidazole therapy. Given the association of trichomoniasis with perinatal morbidity and HIV transmission, women in high-risk groups may benefit from TV PCR.

Double-stranded RNA viral infection of Trichomonas vaginalis infecting patients attending a sexually transmitted diseases clinic.

Trichomonas vaginalis (TV) can be infected with double-stranded RNA (dsRNA) viruses that may have important implications for trichomonal virulence and disease pathogenesis. A cross-sectional study was conducted in a sexually transmitted diseases clinic to determine the prevalence and clinical significance of dsRNA viral infection of TV infecting men and women. Overall, dsRNA virus was present in 21 (75%) of 28 TV isolates (95% confidence interval [CI], 55%-89%). dsRNA viral infection of TV was not associated with the presence of discharge, dysuria, genital pruritus, or genital irritation or odor. However, patients with virus-positive isolates were significantly older than patients with virus-negative isolates (median age, 38 vs. 23 years; P=.003), and virus-positive isolates were more prevalent among women (19 [86%] of 22 isolates; 95% CI, 65%-97%) than among men (2 [33%] of 6 isolates; P=.02). The age and sex specificity of virus-positive isolates may aid in understanding the differences in chronicity and clinical presentation of TV in men and women.
