High Dietary Sodium, Measured Using Spot Urine Samples, is Associated with Higher Blood Pressure among Young Adults in Haiti. Glob Heart 2023; 18:5. [PMID: 36817226 PMCID: PMC9936908 DOI: 10.5334/gh.1187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 01/23/2023] [Indexed: 02/16/2023] Open
Abstract
Background Hypertension (HTN) is the leading cardiovascular disease (CVD) risk factor in Haiti and is likely driven by poverty-related social and dietary factors. Salt consumption in Haiti is hypothesized to be high but has never been rigorously quantified. Methods We used spot urine samples from a subset of participants in the population-based Haiti Cardiovascular Disease Cohort to estimate population mean daily sodium intake. We compared three previously validated formulas for estimating dietary sodium intake using urine sodium, urine creatinine, age, sex, height, and weight. We explored the association between dietary sodium intake and blood pressure, stratified by age group. Results A total of 1,240 participants had spot urine samples. Median age was 38 years (range 18-93), and 48% were female. The mean dietary sodium intake was 3.5-5.0 g/day across the three estimation methods, with 94.2%-97.9% of participants consuming above the World Health Organization (WHO) recommended maximum of 2 g/day of sodium. Among young adults aged 18-29, increasing salt intake from the lowest quartile of consumption (<3.73 g/day) to the highest quartile (>5.88 g/day) was associated with a mean 8.71 mmHg higher systolic blood pressure (SBP) (95% confidence interval: 3.35, 14.07; p = 0.001). An association was not seen in older age groups. Among participants under age 40, those with SBP ≥120 mmHg consumed 0.5 g/day more sodium than those with SBP <120 mmHg (95% confidence interval: 0.08, 0.69; p = 0.012). Conclusions Nine out of 10 Haitian adults in our study population consumed more than the WHO recommended maximum for daily sodium intake. In young adults, higher sodium consumption was associated with higher SBP. This represents an inflection point for increased HTN risk early in the life course and points to dietary salt intake as a potential modifiable risk factor for primordial and primary CVD prevention in young adults.

"Mobilizing our leaders": A multi-country qualitative study to increase the representation of women in global health leadership. PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0000646. [PMID: 36962949 PMCID: PMC10021821 DOI: 10.1371/journal.pgph.0000646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 12/21/2022] [Indexed: 02/01/2023]
Abstract
INTRODUCTION Women play an essential role in health care delivery, and it is vital that they have equal representation in health leadership for equity, innovation, and the strengthening of health systems globally. Yet women remain vastly underrepresented in global health leadership positions, providing a clear example of the deeply rooted power imbalances that are central to the calls to decolonize global health. We conducted a multi-country study in Haiti, Tanzania, India, and the USA to examine gender-based challenges to career advancement for women in the global health workforce. Quantitative data on the type and prevalence of gender-based challenges has been previously reported. In this study, we analyze qualitative data collected through focus group discussions and in-depth interviews to understand women's experiences of gender-based obstacles to career advancement, their perceptions of underlying drivers, and perspectives on effective solutions. Guided by an adaptation of the Social Action Theory, we conducted focus group discussions and in-depth interviews with women at 4 major academic centers for clinical care and research in Haiti, India, Tanzania, and the United States. In total, 85 women participated in focus groups and 15 also participated in in-depth interviews. Discussions and interviews were conducted in the local language, by an experienced local facilitator unaffiliated with the participating institution, between 2017 and 2018. Discussions were recorded, transcribed, and translated. Data were analyzed by interpretive phenomenological methods for emergent themes. Three transcendent themes on gender-based challenges were identified: 1) cultural power imbalance, referring to the prevailing norms and engrained assumptions that women are less capable than men and that women's primary responsibility should be to their families; 2) institutional power imbalance, referring to the systematic gender bias upheld by existing leadership and power structures, and ranging from exclusion from career development opportunities to sexual harassment and assault; and 3) restricted agency, referring to women's limited ability to change their circumstances because of unequal cultural and institutional structures. Participants also described local, actionable solutions to address these barriers. These included: 1) formal reporting systems for sexual harassment and assault; 2) peer support and mentorship; and 3) accessible leadership training and mandatory gender equity training. Participants proposed feasible strategies to address gender-based challenges that could improve women's retention in health careers and foster their rise to leadership. Increasing the representation of women in global health leadership positions responds directly to efforts to decolonize global health and is integral to strengthening health systems and improving health outcomes for women and children worldwide.

High prevalence of obesity among women in urban Haiti: Findings from a population-based cohort. Front Public Health 2022; 10:976909. [PMID: 36276356 PMCID: PMC9581236 DOI: 10.3389/fpubh.2022.976909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 08/23/2022] [Indexed: 01/25/2023] Open
Abstract
Introduction Obesity is associated with increased risk of non-communicable diseases and death and is increasing rapidly in low- and middle-income countries, including Haiti. There is limited population-based data on body mass index (BMI) and waist circumference (WC) and associated risk factors in Haiti. This study describes BMI and WC, and factors associated with obesity using a population-based cohort from Port-au-Prince. Methods Baseline sociodemographic and clinical data were collected from participants in the Haiti CVD Cohort Study between March 2019 and August 2021. Weight was categorized by BMI (kg/m2) with obesity defined as ≥30 kg/m2. Abdominal obesity was defined using WC cutoffs of ≥80 cm for women and ≥94 cm for men based on WHO guidelines. Sociodemographic and behavioral risk factors, including age, sex, educational attainment, income, smoking status, physical activity, fat/oil use, daily fruit/vegetable consumption, and frequency of fried food intake were assessed for their association with obesity using a Poisson multivariable regression. Results Among 2,966 participants, median age was 41 years (IQR: 28-55) and 57.6% were women. Median BMI was 24.0 kg/m2 (IQR: 20.9-28.1) and 508 (17.1%) participants were obese. Women represented 89.2% of the population with BMI ≥30 kg/m2. A total of 1,167 (68.3%) women had WC ≥80 cm and 144 (11.4%) men had WC ≥94 cm. BMI ≥30 kg/m2 was significantly more prevalent among women than men [PR 5.7; 95% CI: (4.3-7.6)], those 40-49 years compared to 18-29 years [PR 3.3; 95% CI: (2.4-4.6)], and those with income >10 USD per day compared to ≤1 USD [PR 1.3; 95% CI: (1.0-1.6)]. There were no significant associations with other health and behavioral risk factors. Discussion In Haiti, women have an alarming 6-fold higher obesity prevalence compared to men (26.5 vs. 4.3%) and 89.2% of participants with obesity were women. Abdominal obesity was high, at 44.3%. Haiti faces a paradox of an ongoing national food insecurity crises and a burgeoning obesity epidemic. Individual, social, and environmental drivers of obesity, especially among women, need to be identified.

Comparison of community and clinic-based blood pressure measurements: A cross-sectional study from Haiti. PLOS GLOBAL PUBLIC HEALTH 2022; 2:e0001064. [PMID: 36285251 PMCID: PMC9592070 DOI: 10.1371/journal.pgph.0001064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 09/03/2022] [Indexed: 11/19/2022]
Abstract
Hypertension (HTN) is the leading modifiable cardiovascular disease (CVD) risk factor in low and middle-income countries, and accurate and accessible blood pressure (BP) measurement is essential for identifying persons at risk. Given the convenience and increased use of community BP screening programs in low-income settings, we compared community and clinic BP measurements for participants in the Haiti CVD Cohort Study to determine the concordance of these two measurements. Participants were recruited using multistage random sampling from March 2019 to August 2021. HTN was defined as systolic BP (SBP) ≥ 140mmHg, diastolic BP (DBP) ≥ 90mmHg or taking antihypertensives according to WHO guidelines. Factors associated with concordance versus discordance of community and clinic BP measurements were assessed with multivariable Poisson regressions. Among 2,123 participants, median age was 41 years and 62% were female. Pearson correlation coefficients for clinic versus community SBP and DBP were 0.78 and 0.77, respectively. Using community BP measurements, 36% of participants screened positive for HTN compared with 30% using clinic BPs. The majority of participants had concordant measurements of normotension (59%) or HTN (26%) across both settings, with 4% having isolated elevated clinic BP (≥140/90 in clinic with normal community BP) and 10% with isolated elevated community BP (≥140/90 in community with normal clinic BP). These results underscore community BP measurements as a feasible and accurate way to increase HTN screening and estimate HTN prevalence for vulnerable populations with barriers to clinic access.

Abstract
Cardiovascular disease (CVD) is the number one cause of death in low-income countries including Haiti, with hypertension (HTN) being the leading risk factor. This study aims to identify gaps in the HTN continuum of screening, diagnosis, treatment, and blood pressure (BP) control. Sociodemographic and clinical data were collected from a population-based sample of adults ≥18 years in Port-au-Prince (PAP) from March 2019 to April 2021. HTN was defined as systolic BP ≥ 140 mmHg, diastolic BP ≥ 90 mmHg, or use of antihypertensive medication. Screening was defined as ever having had a BP measurement; diagnosis as previously being informed of a HTN diagnosis; treatment as having taken antihypertensives in the past 2 weeks; and controlled as taking antihypertensives and having BP < 140/90 mmHg. Factors associated with attaining each step in the continuum were assessed using Poisson multivariable regressions. Among 2737 participants, 810 (29% age-standardized) had HTN, of whom 97% had been screened, 72% diagnosed, 45% treated, and 13% controlled. There were no significant differences across age groups or sex. Obesity (BMI ≥ 30) was a significant factor associated with receiving treatment compared to normal weight (BMI < 25), with a prevalence ratio (PR) of 1.5 (95% CI 1.1-2.0). Having secondary or higher education was associated with higher likelihood of controlled BP (PR 1.9 [95% CI 1.1-3.3]). In this urban Haitian population, the greatest gaps in HTN care are treatment and control. Targeted interventions are needed to improve these steps, including broader access to affordable treatment, timely distribution of medications, and patient adherence to HTN medication.

Estimated blood pressure trajectories and hypertension patterns among pregnant women living with HIV, Haiti, 2007-2017. J Clin Hypertens (Greenwich) 2022; 24:237-245. [PMID: 35129266 PMCID: PMC8925004 DOI: 10.1111/jch.14432] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Revised: 12/27/2021] [Accepted: 12/30/2021] [Indexed: 01/17/2023]
Abstract
Hypertension in pregnancy is a key driver of mortality and morbidity among Haitian women. HIV infection and treatment may worsen hypertension and increase cardiovascular disease risk. The authors examined blood pressure and hypertension patterns among 1965 women (2306 pregnancies ending in live births) in a prevention of maternal-to-child transmission (PMTCT) program in Port-au-Prince, Haiti, between 2007 and 2017. Hypertension was defined as blood pressure ≥140/90 mm Hg on two consecutive visits. Latent class analysis assessed trajectories of mean arterial pressure (MAP) and multinomial ordinal logistic regression examined factors associated with higher trajectories. Between 2007-2009 and 2013-2016, hypertension at PMTCT entry increased from 1.3% to 3.8% (p = .005), while incidence at any time during PMTCT follow-up increased from 5.0 to 16.1 per 100 person-years (p < .001). Hypertension detected ≤20 weeks and > 20 weeks of gestation (possible gestational hypertension) increased from 1.1% to 3.5% (p = .003) and from 2.3% to 6.9% (p < .001), respectively. Five MAP trajectories ranged from low-stable to high-increasing. In multivariable analysis controlling for history of antiretroviral therapy, age, parity, and weight, program entry in more recent years was associated with greater odds of higher MAP trajectory (adjusted odds ratio for 2013-2016 vs. 2007-2009 = 3.1, 95% confidence interval: 1.7-5.6). The increasing prevalence and incidence of hypertension highlight a need for screening and management prior to PMTCT entry and during follow-up. In a population with limited access to chronic disease care, and where many deliveries occur outside of a clinical setting, the period of PMTCT follow-up represents an opportunity to diagnose and initiate management of preexisting and pregnancy-related hypertension.

Abstract
Poor diets are responsible for a large burden of noncommunicable disease (NCD). The prevalence of modifiable dietary risk factors is rising in lower-income countries such as Haiti, along with increasing urbanization and shifts to diets high in sugar, salt, and fat. We describe self-reported dietary patterns (intake of fruits, vegetables, fried food, sugar-sweetened beverages, and added salt and oil) among a population-based cohort of low-income adults in Port-au-Prince and assess for associated sociodemographic factors (age, sex, income, education, body mass index). Among 2989 participants, the median age was 40 years, and 58.0% were women. Less than 1% met the World Health Organization recommendation of at least five servings/day of fruits and vegetables. Participants consumed fried food on average 1.6 days/week and sugar-sweetened beverages on average 4.7 days/week; young males of low socioeconomic status were the most likely to consume these dietary risk factors. The vast majority of participants reported usually or often consuming salt (87.1%) and oil (86.5%) added to their meals eaten at home. Our findings underscore the need for public health campaigns, particularly those targeting young males and household cooks preparing family meals at home, to improve dietary patterns in Haiti in order to address the growing NCD burden.

Abstract
OBJECTIVES To assess the success of a human papillomavirus (HPV) vaccination program among adolescent girls aged 9-14 years in Haiti and to understand predictors of completion of a two-dose HPV vaccination series. METHODS Data collection was conducted during HPV vaccination campaigns in Port-au-Prince between August 2016 and April 2017. Descriptive statistics and logistic regression models were used to examine characteristics associated with vaccination series completion of school based and non-school based vaccination delivery modalities. RESULTS Of the 2,445 adolescent girls who participated in the awareness program, 1,994 participants (1,307 in non-school program, 687 in school program) received the first dose of the vaccine; 1,199 (92%) in the non-school program and 673 (98%) in the school program also received the second dose. Menarche (OR: 1.87; 95% CI, 1.11-3.14), if the participant was a prior patient at the GHESKIO clinics (OR: 2.17; 95% CI, 1.32-3.58), and participating in the school-based program (OR: 4.17; 95% CI, 2.14-8.12) were significantly associated with vaccination completion. CONCLUSIONS Vaccination in school- and non-school-based settings was successful, suggesting that a nationwide HPV vaccination campaign using either approach would be successful using either approach.

Abstract
BACKGROUND Cardiovascular disease (CVD) is the leading cause of mortality among Haitians, having surpassed HIV in the last decade. Understanding the natural history of CVD in Haitians, including the age of onset, prevalence, incidence, and role of major risk factors and social determinants, is urgently needed to develop prevention and treatment interventions. Aim 1: Establish a population-based cohort of 3000 adults from Port-au-Prince and assess the prevalence of CVD risk factors and diseases and their association with social and environmental determinants. Aim 2: Determine the incidence of CVD risk factors and CVD during 2-3.5 years of follow-up and their association with social and environmental determinants. METHODS The Haiti CVD Cohort is a longitudinal observational study of 3000 adults > 18 years in Port-au-Prince (PAP), Haiti. The study population is recruited using multistage random sampling from census blocks. Adults receive blood pressure (BP) measurements in the community and those with elevated BP are referred to the Groupe Haitien d'Etude Sarcome de Kaposi et des Infections Opportunistes Clinic for care. After informed consent, participants undergo a clinical exam with medical history. BP, electrocardiogram, echocardiogram, a study questionnaire on health behaviors, and laboratory specimens. Every 6 months, BP is remeasured. At 12 and 24 months, clinical exams and questionnaires are repeated. Labs are repeated at 24 months. Adjudicated study outcomes include the prevalence and incidence of CVD risk factors (hypertension, diabetes, obesity, dyslipidemia, kidney disease, inflammation, poor diet, smoking, and physical inactivity) and events (myocardial infarction, heart failure, stroke, and CVD mortality). We also measure social determinants including poverty. Depression, stress, social isolation, food insecurity, and lead exposure. Blood, urine, and stool samples are biobanked at study enrollment. DISCUSSION The Haiti CVD Cohort is the largest population-based cohort study evaluating CVD risk factors and CVD among adults in urban Haiti with the goal of understanding the drivers of the CVD epidemic in Haiti. Study outcomes are comparable with existing international cohorts, and the biobank will provide important data for future research. Our goal is to translate findings from this study into pragmatic prevention and treatment interventions to fight the CVD epidemic in Haiti.

Abstract
OBJECTIVE To evaluate mother and infant outcomes in the largest prevention of mother-to-child-transmission (PMTCT) programme in Haiti in order to identify gaps towards elimination of HIV and syphilis. METHODS Based on retrospective data from HIV+ pregnant women and their infants enrolled in PMTCT care from 1999 to 2014, we assessed maternal enrolment in PMTCT, receipt of antiretrovirals before delivery, maternal retention through delivery as well as infant enrolment in PMTCT, HIV testing and HIV infection. Four PMTCT programme periods were compared: period 1 (1999-2004, mono ARV), period 2 (2005-2009, dual ARV), period 3 (2010-2012, Option B) and period 4 (Oct 2012-2014, Option B+). Kaplan-Meier methods were used to assess retention in PMTCT care. RESULTS Among 4665 pregnancies, median age was 27 years and median CD4+ was 494 cells/μl (IQR 328-691). A total of 75% of women received antiretrovirals before delivery, and 73% were retained in care through delivery. Twenty-two percent of women were lost before delivery, <1% died and 6% had stillbirths or abortions. Ninety-four percent of infants who were born alive enrolled in PMTCT, of whom 92% had complete HIV testing. One hundred and sixty-one infants were HIV+, giving a 5.4% HIV transmission rate (9.8%, 4.6%, 5.8% and 3.6% in periods 1-4). Retention among women through 12 months after PMTCT enrolment did not significantly differ across periods. However, among women who received antiretrovirals at the time of enrolment, retention 12 months later was lower in the Option B+ period (83%) than in periods 2 and 3 (94% and 93%) (P < 0.001). Syphilis infection among women decreased from 16% in period 1 to 8% in period 4, whereas syphilis testing of infants increased from 17% to 91%. CONCLUSION Despite dramatic reductions in MTCT in Haiti, interventions are needed to improve retention to achieve MTCT elimination of HIV and syphilis.

Abstract
Leadership positions in global health are greatly skewed toward men; the imbalance is more pronounced in low- and middle-income countries (LMICs). The under-representation of women in leadership is a threat to gender equality, and also impacts the improvement of women's health outcomes globally. In this perspectives piece, we assert that the promotion and retention of women in global health leadership has a ripple effect that can achieve improvement in global health outcomes. We present pragmatic, actionable solutions to promote and retain female global health leaders in this field.

Abstract
BACKGROUND Identifying cohorts of Caribbean women with HIV infection rates sufficient for inclusion in HIV vaccine efficacy trials has been challenging. HVTN 907 determined the feasibility of identifying and retaining a cohort of women at high risk for HIV acquisition by focusing recruitment on female sex workers (FSWs). METHODS HIV uninfected FSWs, residing in Haiti, Dominican Republic, and Puerto Rico, who reported unprotected sex and met previously described more stringent site-specific eligibility criteria, were eligible. Behavioral risk assessment, HIV counseling and testing, and pregnancy testing were performed at baseline, 6, 12, and 18 months. RESULTS Among 799 FSWs (264 from Dominican Republic, 334 from Haiti, and 201 from Puerto Rico), the median age was 26 years, with 54% having less than a high school education and 45% having a monthly household income of less than $US 100. Median number of male partners 6 months before screening was 200. Retention at 18 months was 93%. Twelve women became HIV infected, 9 from Haiti. The annualized HIV incidence was 1.07% (95% confidence interval: 0.55% to 1.87%). Pregnancy incidence was 22.5% (95% confidence interval: 21.9% to 29.5%). Statistically significant declines in risk behaviors occurred between screening and the 18-month visit assessment. DISCUSSION The HVTN 907 study identified a high-risk cohort of women with excellent retention for all 3 sites, despite major challenges especially in Haiti. These results show that a bridging study of a vaccine shown to be efficacious in other clade settings would be possible among FSWs in the region, particularly in Haiti.

Abstract
Successful and sustained efforts have been made to curtail the major cholera epidemic that occurred in Haiti in 2010 with the promotion of hygiene and sanitation measures, training of health personnel and establishment of treatment centers nationwide. Oral cholera vaccine (OCV) was introduced by the Haitian Ministry of Health as a pilot project in urban and rural areas. This paper reports the successful OCV pilot project led by GHESKIO Centers in the urban slums of Port-au-Prince where 52,357 persons received dose 1 and 90.8% received dose 2; estimated coverage of the at-risk community was 75%. This pilot study demonstrated the effort, community mobilization, and organizational capacity necessary to achieve these results in a challenging setting. The OCV intervention paved the way for the recent launching of a national cholera vaccination program integrated in a long-term ambitious and comprehensive plan to address Haiti's critical need in water security and sanitation.

Recruitment of Caribbean female commercial sex workers at high risk of HIV infection. Rev Panam Salud Publica 2013; 34:92-98. [PMID: 24096973 PMCID: PMC4008335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2012] [Accepted: 07/16/2013] [Indexed: 06/02/2023] Open
Abstract
OBJECTIVE To evaluate novel eligibility criteria and outreach methods to identify and recruit women at high risk of HIV-1 infection in the Caribbean. METHODS A prospective cohort study was conducted in 2009-2012 among 799 female commercial sex workers in the Dominican Republic, Haiti, and Puerto Rico. Minimum eligibility criteria included exchange of sex for goods, services, or money in the previous 6 months and unprotected vaginal or anal sex with a man during the same period. Sites used local epidemiology to develop more stringent eligibility criteria and recruitment strategies. Participants were asked questions about HIV/AIDS and their level of concern about participating in an HIV vaccine trial. Logistic regression modeling was used to assess predictors of prevalent HIV infection and willingness to participate in a future HIV vaccine study. RESULTS HIV prevalence at screening was 4.6%. Crack cocaine use [odds ratio (OR) = 4.2, 95% confidence interval (CI) (1.8-9.0)] was associated with and having sex with clients in a hotel or motel [OR = 0.5, CI (0.3-1.0)] was inversely associated with HIV infection. A total of 88.9% of enrolled women were definitely or probably willing to participate in a future HIV vaccine trial. CONCLUSIONS This study indicated that local eligibility criteria and recruitment methods can be developed to identify and recruit commercial sex workers with higher HIV prevalence than the general population who express willingness to join an HIV vaccine trial.

Abstract
BACKGROUND HIV voluntary counseling and testing (VCT) may be an effective strategy to prevent transmission of HIV in developing countries. Hypothesizing that primary care services and HIV VCT have synergistic benefits, we examine the feasibility, the demand, and the effect of integrating on-site primary care services into VCT at a stand-alone VCT center in Port au Prince, Haiti. METHODS Through a retrospective review of patient records, we describe the integration of primary care services at the Groupe Haitien d'Etude du Sarcome de Kaposi et des Infections Opportunistes (GHESKIO) VCT center between1985 and 2000. RESULTS Between 1985 and 1999, services for HIV care, tuberculosis care, treatment of sexually transmitted diseases, and reproductive health were sequentially integrated into HIV VCT at GHESKIO. The number of new people seeking voluntary counseling and testing at GHESKIO increased from 142 in 1985 to 8175 in 1999, with an increasing percentage of women, adolescents, symptom-free clients, and self-referred clients. Of new adults seeking VCT in 1999, the center was able to provide AIDS care to 17%, tuberculosis treatment to 6%, sexually transmitted infection management to 18%, and family planning to 19%. HIV transmission between discordant couples was 0 infections/100 follow-up years (95% CI, 0-3.2); vertical transmission from mother to child was 11 infections/100 live births (95% CI, 4.6-21.9); These rates are significantly lower than expected rates of transmission in Haiti. CONCLUSIONS This report demonstrates the feasibility, demand, and effective synergy of integrating on-site primary care services into HIV VCT in Haiti. VCT is a good entry point for people in need of services for communicable diseases and reproductive health, and, reciprocally, services attract more people to VCT, including populations that are at high risk for HIV infection. This program is being duplicated elsewhere in Haiti and can serve as a model for other countries.

Abstract
OBJECTIVE A study was conducted to define the natural history and disease progression of HIV infection in a developing country. DESIGN A prospective longitudinal cohort study. METHODS Forty-two patients with documented dates of HIV seroconversion were followed in Port-au-Prince, Haiti. Patients were seen at 3 month intervals or when ill. Patients were treated for bacterial, mycobacterial, parasitic, and fungal infections, but antiretroviral therapy was not available. Patients were followed until death or until 1 January 2000; median follow-up was 66 months. RESULTS By Kaplan-Meier analyses, the median time to symptomatic HIV disease (CDC category B or C) was 3.0 years [95% confidence interval (CI) 2.3-5.0 years]. The median time to AIDS (CDC category C) was 5.2 years (95% CI 4.7-6.5 years), and the median time to death was 7.4 years (95% CI 6.2-10.2 years). Community-acquired infections, including respiratory tract infections, acute diarrhea, and skin infections were common in the pre-AIDS period. AIDS-defining illnesses included tuberculosis, wasting syndrome, cryptosporidiosis, cyclosporiasis, candida esophagitis, toxoplasmosis, and cryptococcal meningitis. Rapid progression to death was associated with anemia at the time of seroconversion hazards ratio (HR) 4.1 (95% CI 1.1-15.0), age greater than 35 years at seroconversion HR 4.4 (95% CI 1.1-16.6), and lymphopenia at seroconversion HR 11.0 (95% CI 2.3-53.0). CONCLUSION This report documents rapid disease progression from HIV seroconversion until death among patients living in a developing country. Interventions, including nutritional support and prophylaxis of common community-acquired infections during the pre-AIDS period may slow disease progression and prolong life for HIV-infected individuals in less-developed countries.

Abstract
BACKGROUND Despite the importance of human immunodeficiency virus (HIV) transmission through heterosexual contact, the incidence of HIV infection in heterosexual cohorts has not been well studied, particularly in the developing world. OBJECTIVE To 1) determine the incidence of HIV infection in discordant heterosexual couples (couples in which one partner had HIV infection and the other did not) in Haiti and 2) assess risk factors for and methods of preventing HIV infection. DESIGN Prospective study. SETTING National Institute for Laboratory Research, Portau-Prince, Haiti. PARTICIPANTS 475 HIV-infected patients and their noninfected regular sex partners. MEASUREMENTS Patients and their partners were evaluated at 3- to 6-month intervals for HIV infection, sexually transmitted diseases, and sexual practices. The efficacy of counseling and provision of free condoms was also evaluated. RESULTS Among the 177 couples who remained sexually active during the prospective study period, 20 seroconversions to HIV positivity occurred, for an incidence rate of 5.4 per 100 person-years (95% CI, 5.16 to 5.64 per 100 person-years). Thirty-eight couples (21.5%) discontinued sexual activity during the study. Only 1 seroconversion occurred among the 42 sexually active couples (23.7% of the 177 sexually active couples) who always used condoms. In contrast, the incidence in sexually active couples who infrequently used or did not use condoms was 6.8 per 100 person-years (CI, 6.49 to 7.14 per 100 person-years). Transmission of HIV was associated with genital ulcer disease, syphilis, and vaginal or penile discharge in the HIV-negative partner and with syphilis in the HIV-infected partner. CONCLUSION Counseling and the provision of free condoms contributed to the institution of safe sex practices or abstinence in 45% of discordant heterosexual couples. However, 55% of couples reported that they continued to have unprotected sex, resulting in an incidence of HIV infection of 6.8 per 100 person-years.

Abstract
An observational study of 140 HIV-seropositive asymptomatic women of childbearing age was conducted in Haiti from 1984 to 1992 as part of a larger natural history study. Forty-four women were pregnant or became pregnant during the study period. The progression to HIV-related disease, AIDS, and mortality from AIDS was compared in the pregnant and nonpregnant cohorts. The mean follow-up time was 44 months. Overall, 32 of the 140 women (38%) developed AIDS, and 26 (19%) died from AIDS during the study period, with a cumulative AIDS incidence rate of 16% at 3 years after study entry. There was a trend toward earlier manifestation of HIV-related symptoms among the pregnant cohort, but no significant difference was observed in the rate of progression to AIDS or death between the pregnant and nonpregnant women.

Abstract
AIDS is inexorably involving all parts of the country and all strata of society, with 10% of the urban and 3% of the rural population infected with HIV. It is increasingly a disease of women and children. The major cofactors for transmission are also sexually transmitted. For most developing countries, in spite of all education efforts, the "silent epidemic" of AIDS continues. AIDS is known but not understood; counselling modifies behavior in only 10-20% of at-risk persons. Under optimal conditions, HIV discordant females have seroconversion rates of 4.7% per year and pregnancy rates of 10.4% per year. The recent political unrest in Zaire and Haiti will further enhance the spread of AIDS in these countries. Despite these difficult periods, the work can and must continue. After all, during our 10th year of collaboration with a Haitian private research group, the Haitian government and Cornell University, Haiti has known seven different political rulers. Finally, I want to make a pledge on behalf of the millions of people who face a certain death from HIV infection and AIDS and who will never make the front page of any newspaper. For these people, you can make a difference. You must give us the tools to carry on this fight. The clinical trials must be done where they are most needed: the developing countries. Vaccines represent the only viable alternative despite the recognized obstacles of viral heterogeneity, immunogenicity, and delivery.

Abstract
During July 1983 to December 1984, we observed that 62 (46%) of 134 Haitian patients with acquired immunodeficiency syndrome had intensely pruritic eruptions for which neither specific causative nor categoric diagnoses could be established. These lesions were a presenting manifestation of acquired immunodeficiency syndrome in 79% of the patients and appeared a mean of 8 months before the diagnosis of either Kaposi's sarcoma or opportunistic infection. Lesions included erythematous round macules, papules, or nodules that first appeared on the extensor surface of the arms, but subsequently involved the legs, trunk, and face. Histologically, the lesions were characterized by varying degrees of mixed (predominantly eosinophilic) perivascular and perifollicular inflammatory cell infiltrates of the dermis. The lesions did not respond to any therapeutic regimens used and usually persisted throughout the acquired immunodeficiency syndrome illness. Demographic and laboratory data did not distinguish these patients from those without pruritic skin lesions.

Abstract
We conducted a randomized prospective study to compare the efficacy of oral miconazole and ketoconazole in the treatment of candida esophagitis in acquired immune deficiency syndrome (AIDS) patients in Haiti. Twelve AIDS patients with endoscopic and microscopic diagnoses of candida esophagitis were placed on either oral miconazole or ketoconazole for 10 days. All six patients receiving oral miconazole, and four of the six receiving ketoconazole had complete resolution of their esophageal lesions at the end of treatment. We conclude oral miconazole is at least as effective as ketoconazole in the treatment of candida esophagitis in AIDS patients.
