Heart Failure Care Facilitators and Barriers in Rural Haiti: A Qualitative Study.

Background: Heart failure (HF) is a leading cause of hospitalizations in Haiti. However, few patients return for outpatient care. The factors contributing to chronic HF care access are poorly understood. Objective: The purpose of this study is to investigate the facilitators and barriers to accessing care for chronic HF from the patients' perspectives. Methods: We conducted a qualitative descriptive study of 13 patients with HF participating in three group interviews and one individual interview. We recruited patients after discharge from a nongovernmental organization-supported academic hospi…

Genetic analysis reveals unique characteristics of Plasmodium falciparum parasite populations in Haiti.

BACKGROUND: With increasing interest in eliminating malaria from the Caribbean region, Haiti is one of the two countries on the island of Hispaniola with continued malaria transmission. While the Haitian population remains at risk for malaria, there are a limited number of cases annually, making conventional epidemiological measures such as case incidence and prevalence of potentially limited value for fine-scale resolution of transmission patterns and trends. In this context, genetic signatures may be useful for the identification and characterization of the Plasmodium falciparum parasite pop…

A mixed methods, community-based investigation on women's cancer awareness in Haiti.

Despite a high number of cases, the awareness of breast and cervical cancer in Haiti and other low and middle-income countries (LMICs) remains relatively unknown. The objective of the research was to understand perceptions and attitudes towards breast and cervical cancer in Haiti through community-engaged research. We report Haitians perceptions of breast and cervical cancer symptoms, diagnosis, complications, treatment, community support and access to medical services. Five non-governmental Haitian organisations performed a large survey across the country of Haiti in 2015. The survey and focu…

Estimating effectiveness of case-area targeted response interventions against cholera in Haiti.

Case-area targeted interventions (CATIs) against cholera are conducted by rapid response teams, and may include various activities like water, sanitation, hygiene measures. However, their real-world effectiveness has never been established. We conducted a retrospective observational study in 2015-2017 in the Centre department of Haiti. Using cholera cases, stool cultures and CATI records, we identified 238 outbreaks that were responded to. After adjusting for potential confounders, we found that a prompt response could reduce the number of accumulated cases by 76% (95% confidence interval, 59 …

Multiple traumas and resilience among street children in Haiti: Psychopathology of survival.

In Haiti, as in several developing countries, the phenomenon of street children has become a major public health issue. These children are often victims of traumas and adverse life events. This article aimed to investigate traumas experienced by street children and their coping and resilience strategies used to deal with adversities in a logic of survival, relying on a mixed method approach. A group of 176 street children, aged 7-18 (n = 21 girls), recruited in Port-au-Prince, completed measures assessing PTSD, social support and resilience. Semi-structured interviews were conducted to documen…

Prevalence, risk factors and associated complications of postpartum hypertension in rural Haiti.

BACKGROUND: The prevalence of hypertensive disorders during pregnancy is high in developing countries such as Haiti, however little is known about postpartum hypertension (PPHTN). METHODS: This is a prospective study done at Hospital Albert Schweitzer in rural Haiti among pregnant women age 18 or older who were admitted for labor. Blood pressures were collected before and after delivery and medical charts were reviewed to gather delivery characteristics and fetal/neonatal outcomes. Differences between groups are presented based on postpartum blood pressures (BP) as mild PPHTN (systolic BP≥140…

Outcomes after antiretroviral therapy during the expansion of HIV services in Haiti.

BACKGROUND: We report patient outcomes after antiretroviral therapy (ART) initiation in a network of HIV facilities in Haiti, including temporal trends and differences across clinics, during the expansion of HIV services in the country. METHODS: We assessed outcomes at 12 months after ART initiation (baseline) using routinely collected data on adults (≥15 years) in 11 HIV facilities from July 2007-December 2013. Outcomes include death (ascertained from medical records), lost to follow-up (LTF) defined as no visit > 365 days from ART initiation, and retention defined as being alive and attendi…

Cost Evaluation of a Government-Conducted Oral Cholera Vaccination Campaign-Haiti, 2013.

The devastating 2010 cholera epidemic in Haiti prompted the government to introduce oral cholera vaccine (OCV) in two high-risk areas of Haiti. We evaluated the direct costs associated with the government's first vaccine campaign implemented in August-September 2013. We analyzed data for major cost categories and assessed the efficiency of available campaign resources to vaccinate the target population. For a target population of 107,906 persons, campaign costs totaled $624,000 and 215,295 OCV doses were dispensed. The total vaccine and operational cost was $2.90 per dose; vaccine alone cost $…

Médecins sans frontières experience in orthopedic surgery in postearthquake Haiti in 2010.

INTRODUCTION: During January 2010, a 7.0 magnitude earthquake struck Haiti, resulting in death and destruction for hundreds of thousands of people. This study describes the types of orthopedic procedures performed, the options for patient follow-up, and limitations in obtaining outcomes data in an emergency setting. PROBLEM: There is not a large body of data that describes larger orthopedic cohorts, especially those focusing on internal fixation surgeries in resource-poor settings in postdisaster regions. This article describes 248 injuries and over 300 procedures carried out in the Médecins …

Glucose-6-phosphate dehydrogenase deficiency A- variant in febrile patients in Haiti.

Haiti is one of two remaining malaria-endemic countries in the Caribbean. To decrease malaria transmission in Haiti, primaquine was recently added to the malaria treatment public health policy. One limitation of primaquine is that, at certain doses, primaquine can cause hemolytic anemia in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency (G6PDd). In this study, we genotyped two mutations (A376G and G202A), which confer the most common G6PDd variant in West African populations, G6PDd A-. We estimated the frequency of G6PDd A- in a sample of febrile patients enrolled in an on…

Monitoring water sources for environmental reservoirs of toxigenic Vibrio cholerae O1, Haiti.

An epidemic of cholera infections was documented in Haiti for the first time in more than 100 years during October 2010. Cases have continued to occur, raising the question of whether the microorganism has established environmental reservoirs in Haiti. We monitored 14 environmental sites near the towns of Gressier and Leogane during April 2012-March 2013. Toxigenic Vibrio cholerae O1 El Tor biotype strains were isolated from 3 (1.7%) of 179 water samples; nontoxigenic O1 V. cholerae was isolated from an additional 3 samples. All samples containing V. cholerae O1 also contained non-O1 V. choler…

High-frequency rugose exopolysaccharide production by Vibrio cholerae strains isolated in Haiti.

In October, 2010, epidemic cholera was reported for the first time in Haiti in over 100 years. Establishment of cholera endemicity in Haiti will be dependent in large part on the continued presence of toxigenic V. cholerae O1 in aquatic reservoirs. The rugose phenotype of V. cholerae, characterized by exopolysaccharide production that confers resistance to environmental stress, is a potential contributor to environmental persistence. Using a microbiologic medium promoting high-frequency conversion of smooth to rugose (S-R) phenotype, 80 (46.5%) of 172 V. cholerae strains isolated from clinical…

Costs of integrated mass drug administration for neglected tropical diseases in Haiti.

We conducted a cost analysis of Haiti's Ministry of Public Health and Population neglected tropical disease program, Projet des Maladies Tropicales Negligées and collected data for 9 of 55 communes participating in the May 2008-April 2009 mass drug administration (MDA). The Projet des Maladies Tropicales Negligées Program partnered with IMA World Health and Hôpital Ste. Croix to implement MDA for treatment of lymphatic filariasis and soil-transmitted helminthiasis by using once a year treatment with albendazole and diethylcarbamazine in a population of approximately 8 million persons. Methods …

Months after a 7.0 magnitude earthquake hit Port-au-Prince, Haiti, over one million remain homeless and living in spontaneous internally displaced person (IDP) camps. Billions of dollars from aid organizations and government agencies have been pledged toward the relief effort, yet many basic human needs, including food, shelter, and sanitation, continue to be unmet. The Sphere Project, "Humanitarian Charter and Minimum Standards in Disaster Response," identifies the minimum standards to be attained in disaster response. From a human rights perspective and utilizing key indicators from the Sphe…

Symptoms reported after mass drug administration for lymphatic filariasis in Leogane, Haiti.

Mass drug administration (MDA) for lymphatic filariasis (LF) can cause adverse reactions from microfilarial and adult worm death. Symptoms after the fifth annual MDA in Leogane, Haiti, were studied to determine whether they resulted from parasite death. Persons reporting post-MDA systemic symptoms at 5 of 148 drug distribution posts and men reporting scrotal pain at any post were interviewed. Participants were tested with immunochromatographic tests (ICTs), and men with scrotal symptoms were examined. At the five posts, 3,781 persons took anti-filarial medication. Of these, 314 (8%) returned w…

Mansonella ozzardi in Haiti. IV. Evaluation of antibody reactivity to heterologous antigens.

Sera from individuals in an area of Haiti endemic for Mansonella ozzardi were analyzed for reactivity to antigens of Brugia pahangi, Dirofilaria immitis, Mansonella llewellyni or Ascaris lumbricoides using either an enzyme-linked immunosorbent assay or an indirect immunofluorescent antibody test. IgM and IgG reactivity to all antigens was observed with sera from both microfilaremic and amicrofilaremic individuals when compared to reactivity of sera from individuals from nonendemic areas. Antibody reactivity to B. pahangi was greater than that to other antigens. IgG reactivity of sera from ende…

Observations on two strains of plasmodium falciparum from Haiti in Aotus monkeys.

Two strains of Plasmodium falciparum originating in Haiti were studied in the Aotus monkey. The Haitian I/CDC strain was first adapted to in vitro cultivation and subsequently inoculated into monkeys. The Haitian III/CDC strain was inoculated directly from a human patient into the Aotus monkey. The strains varied in their levels of pathogenicity to the animals. The Haitian I/CDC strain was highly virulent in six splenectomized animals; in one intact animal, the infection could be controlled but not eliminated with periodic doses of quinine and chloroquine. After subsequent splenectomy, the ani…
