RESUMO
OBJECTIVES: Health-related quality of life (HRQL) in type 1 diabetes is a critical health outcome but has not been studied in many low-income countries. In this study we evaluated the validity of 2 HRQL instruments, measured the HRQL and explored the association between HRQL and glycemic control. METHODS: This was a cross-sectional study of Haitian youth with diabetes between 0 and 25 years of age and living in Haiti. We administered the 51-item Diabetes Quality of Life for Youth (DQOLY) questionnaire and the EuroQol Visual Analogue Scale (EQ-VAS). Psychometric analyses evaluated internal consistency and construct validity of the DQOLY and its 21-item short form, the DQOLY-SF. Linear regression was used to identify predictors of HRQL and glycated hemoglobin (A1C). RESULTS: In 85 youth (59% female; mean age, 17.5 years; mean diabetes duration, 3.7 years; mean A1C, 11.3%), DQOLY and DQOLY-SF had adequate internal consistency with Cronbach's alpha values of 0.86 and 0.84, respectively. Confirmatory factor analysis revealed adequate validity for the DQOLY-SF and DQOLY Satisfaction subscale. HRQL, as measured using the DQOLY-SF, was 62±16 (mean ± standard deviation) out of 100. Mean EQ-VAS score was 78±24 out of 100. Older age (p=0.004), female sex (p=0.02) and lower socioeconomic status (SES) (p=0.03) were risk factors for lower DQOLY score, and older age (p=0.02) and marginally female sex (p=0.06) for lower DQOLY-SF score. No predictors of EQ-VAS were identified. HRQL measures were not associated with glycemic control. CONCLUSIONS: The DQOLY-SF and DQOLY Satisfaction subscale are valid measures of HRQL in Haitian youth with diabetes. HRQL is low and was worse in older, female and low-SES youth, but was not associated with glycemic control.

INTRODUCTION: Controlling insulin-treated diabetes is challenging in low-resource settings where only Neutral Protamine Hagedorn (NPH), regular (R) and premixed insulin formulations are available, self-monitoring of blood glucose (SMBG) supplies are scarce and food insecurity is common. We examined the impact of a treatment protocol that includes sliding scale-based 70/30 insulin adjustments in Haiti. METHODS: Thirty young patients aged 11-28 years with diabetes treated with premixed 70/30 insulin twice daily were included in the study. The participants performed one or two daily self-monitoring of blood glucose (SMBG) tests and attended our diabetes clinic monthly. They were randomized to two treatment groups, with one group remaining on the 70/30 insulin formulation (group 70 [G70]) and the other group switching to self-mixed NPH + R (group NR [GNR]). Sliding scales for insulin correction doses and meal insulin doses were designed based on the total daily insulin dose (TDD), carbohydrate ratio and insulin sensitivity factor. SMBG tests and insulin were administered before the morning and evening meals. The frequency of visits to the diabetes clinic was increased to biweekly during a 14-week follow-up. RESULTS: Fifteen patients of each group were included in the analysis. Baseline characteristics, increase in total daily dose and number of missed SMBG tests and skipped meals at 14 weeks did not differ between the two groups. Hemoglobin A1c (HbA1c) decreased from 9.5% (interquartile range [IQR] 8.8, 10.5) (80.3 mmol/mol) to 8.0% (IQR 7.1%, 9.0%) (63.9 mmol/mol) in G70 (p = 0.01), and from 10.6% (IQR 8.1,% 13.1)% (92.4 mmol/mol) to 9.0% (IQR 7.6%, 9.6%) (74.9 mmol/mol) in GNR (p = 0.10), with no significant between-group difference in reductions (p = 0.12). No serious acute complications were reported. Stopping the use of sliding scales and resuming monthly visits increased HbA1c to values not significantly different from baseline in both groups after 15 weeks. CONCLUSION: The use of sliding scales adjusted for missed SMBG tests and skipped meals, and frequent clinic visits that focus on patient self-management education significantly improved glycemic control in the patients with youth-onset diabetes in our study treated with premixed 70/30 human insulin in a low-resource setting.
RESUMO
BACKGROUND: The prevalence of non-communicable diseases (NCDs) is rising in low and middle-income countries (LMIC). We aimed to report on the prevalence of NCDs in pregnancy and their associated perinatal outcomes in a regional hospital in Haiti. METHODS: We conducted the "Diabète et hYpertension Artéerielle et leurs issues MAternelles et Néonatales" (DYAMAN) prospective cohort study in a regional hospital in Haiti. Pregnant women presenting to care at 24-28 weeks were screened and treated for diabetes (DM) and hypertensive disorders of pregnancy (HDP) using setting-adapted protocols. Prevalence of NCDs and associated maternal-neonatal outcomes were described. RESULTS: 715 women were included, of which 51 (7.1%) had DM, 90 (12.6%) had HDP, and 30 (4.2%) had both DM and HDP (DM/HDP). Of 422 (59%) women delivered in hospital, 58 (13.7%) had preeclampsia, including 5 (8.6%) with eclampsia. Preterm birth <32 weeks was more common in the HDP than the control, DM, and DM/HDP groups. More low birth weight babies (n = 20, 25.6%) were born to the HDP group than to the control (n = 20, 7.1%), DM (n = 1, 2.7%), and DM/HDP (n = 3, 12%) groups (P < 0.001). Macrosomia and hypoglycemia affected 5 (8%) neonates of women with DM. Perinatal mortality, affecting 36/1000 births, was mainly driven by maternal NCDs. CONCLUSIONS: NCDs in pregnancy led to adverse maternal and perinatal outcomes. This study will help to prepare future refinements aimed at optimizing the management of NCDs in pregnancy in LMIC. Research is required to understand barriers to patient attendance at antenatal follow-up, treatment escalation for hyperglycemia, and in-hospital delivery.

Diabetes prevalence within the global population has nearly doubled since 1980, with the most rapid growth occurring in low- and middle-income countries. Diabetes management in resource-limited settings such as Haiti presents many challenges, including the storage of insulin. Despite a lack of published data on insulin thermostability, storage at 2-8°C or at room temperature (25°C) is recommended. In Haiti, access to refrigeration and thereby proper insulin storage is severely limited. Commercial storage devices such as the FRIO cooling wallet are cost-prohibitive and not available locally, and alternatives such as small clay pots are fragile and nonportable. Here, we designed and tested the cooling efficacy of a homemade wallet made of acrylate polymer beads and a hand-sewn cotton pouch compared to a FRIO wallet and a clay pot. All studies were conducted over a ten-day period at the Kay Mackenson Clinic in Montrouis, Haiti. Temperature and humidity values were continuously collected using wireless monitors placed inside each device, and hourly ambient temperature and humidity values were manually recorded. Evaporative cooling efficacy was calculated using collected data. The homemade wallet and FRIO cooling wallet demonstrated comparable cooling efficacy with an average of 71% and 73%, respectively. The clay pot demonstrated significantly decreased efficacy with an average of 27% (p < 0.05). The homemade insulin wallet is a promising alternative for the storage of insulin in low-resource settings without the financial and physical barriers of commercial and locally sourced devices. Additionally, this wallet could be readily adapted for the storage of other perishable medical supplies in low-income countries.

Non-communicable diseases (NCDs) are important contributors to maternal morbidity and mortality worldwide. Yet, data on their prevalence and related outcomes in low-income countries are currently lacking. Additionally, screening and treatment protocols adapted for resource-limited settings are urgently required. This collaborative research initiative on the screening and management of hypertensive disorders of pregnancy and gestational diabetes was conducted in Saint-Nicolas Hospital in Saint-Marc, Haiti. The report discusses methods used to overcome several local challenges to implementation of care for NCDs. It also describes how collaborative research initiatives are efficient strategies to innovate and build research capacity for NCD care delivery during pregnancy in low-income countries.

OBJECTIVE: Few studies have reported blood lead levels (BLLs) in Haitian children, despite the known presence of lead from environmental factors such as soil, water, leaded paint and gasoline, improperly discarded batteries, and earthquakes. We sought to determine the prevalence of elevated blood lead levels (EBLLs) among healthy Haitian children. METHODS: We enrolled children aged 9 months to 6 years from 3 geographic areas in Haiti (coastal, urban, and mountain) from March 1 through June 30, 2015. We obtained anthropometric measurements, household income, potential sources of lead exposure, and fingerstick BLLs from 273 children at 6 churches in Haiti. We considered a BLL ≥5 µg/dL to be elevated. RESULTS: Of 273 children enrolled in the study, 95 were from the coastal area, 78 from the urban area, and 100 from the mountain area. The median BLL was 5.8 µg/dL, with higher levels in the mountain area than in the other areas ( P < .001). BLLs were elevated in 180 (65.9%) children. The prevalence of EBLL was significantly higher in the mountain area (82 of 100, 82.0%; P < .001) than in the urban area (42 of 78, 53.8%) and the coastal area (56 of 95, 58.9%; P < .001). Twenty-eight (10.3%) children had EBLLs ≥10 µg/dL and 3 (1.1%) children had EBLLs ≥20 µg/dL. Exposure to improperly discarded batteries ( P = .006) and living in the mountain area ( P < .001) were significant risk factors for EBLLs. CONCLUSIONS: More than half of Haitian children in our study had EBLLs. Public health interventions are warranted to protect children in Haiti against lead poisoning.

BACKGROUND: Ophthalmic complications of pediatric diabetes are rare, and rates are unknown in Haitian youth. OBJECTIVES: To determine the prevalence and predictors of diabetic retinopathy (DR) and cataracts in a cohort of Haitian youth with insulin-treated diabetes. METHODS: We performed a cross-sectional retrospective review of pediatric patients with diabetes from a pediatric chronic disease center in Haiti, from December 1, 2012 to November 1, 2016. Data collection included demographic and anthropometric information, total daily insulin dose and result of eye examination by a local ophthalmologist. RESULTS: Of 67 patients (54% female, mean age at diagnosis 14.6 ± 3.9 years, mean diabetes duration 3.3 ± 3.0 years, mean HbA1c 84 ± 22 mmol/mol (9.8% ± 2.0%), mean current insulin requirement 0.49 ± 0.28 IU/kg/day), DR was diagnosed in 10/57 (18%) and cataracts in 10/62 (16%), at a mean age of 19.0 ± 4.3 and 19.1 ± 3.3 years, respectively. Diabetes duration was 4.9 ± 5.4 and 3.0 ± 1.5 years at the time of diagnosis of DR and cataracts, respectively. Age at complication, insulin requirement, sex, body mass index, family history, mean HbA1c and diabetes duration were not significant predictors of an ocular complication. CONCLUSIONS: In this cohort of Haitian youth, DR and cataracts occur prematurely. Low-insulin requirements years after diagnosis, possibly allowing for prolonged undetected hyperglycemia prediagnosis, may explain complication risk. The phenotypes of diabetes in pediatric populations of African ancestry may be distinct. Ophthalmologic evaluation should possibly start at diagnosis, and screening guidelines may need to be adapted.

Context: Iodine deficiency is the leading cause of preventable neurodevelopmental delay in children worldwide and a possible public health concern in Haiti. Objective: To determine the prevalence of iodine deficiency in Haitian young children and its influence by environmental factors. Design: Cross-sectional study, March through June 2015. Setting: Community churches in 3 geographical regions in Haiti. Participants: 299 healthy Haitian children aged 9 months to 6 years; one-third each enrolled in a coastal, mountainous, and urban region. Main Outcome Measures: Urinary iodide, serum thyrotropin (TSH), goiter assessment, and urinary perchlorate and thiocyanate. Results: Mean age was 3.3±1.6 years, with 51% female, median family income USD 30/week, and 16% malnutrition. Median urinary iodide levels were normal in coastal (145 µg/L, interquartile range [IQR] 97 to 241) and urban regions (187 µg/L, IQR 92 to 316), but revealed mild iodine deficiency in a mountainous region (89 µg/L, IQR 56 to 129), P < 0.0001. Grade 1 goiters were palpated in 2 children, but TSH values were normal. Urinary thiocyanate and perchlorate concentrations were not elevated. Predictors of higher urinary iodide included higher urinary thiocyanate and perchlorate, breastfeeding, and not living in a mountainous region. Conclusions: Areas of mild iodine deficiency persist in Haiti's mountainous regions. Exposure to two well-understood environmental thyroid function disruptors is limited.

The impact of chikungunya virus (CHIKV) infection on diabetic patients (DPs) has not been described. We aimed to compare clinical features of CHIKV infection in DPs and nondiabetic patients (NDPs), and to evaluate its effects on glycemic control among DPs. We recorded clinical information and, in DPs, glycemic control. Forty-six DPs and 53 NDPs aged ≥ 20 years living in Haiti, with acute CHIKV infection, were studied. Diabetes duration was 7.1 ± 6.1 years. The most common acute CHIKV clinical manifestations were arthralgia (100.0% DPs and 98.1% NDPs, P = 1.000) and fever (86.9% DPs and 90.5% NDPs, P = 0.750). In DPs as compared with NDPs, arthralgia was more intense (mean pain score of 6.0/10 ± 2.2 versus 5.1/10 ± 2.0, P = 0.04) and took longer to improve (8.2 ± 3.0 versus 3.5 ± 2.5 days, P < 0.0001). Severe arthralgia was more prevalent (58.7% versus 20.8%, P = 0.0002), as was myalgia (80.4% versus 50.9%, P = 0.003), and fever lasted longer (5.1 ± 1.8 versus 3.7 ± 1.7 days, P = 0.0002). Among DPs, median fasting capillary glucose before versus after disease onset was 132.5 and 167.5 mg/dL (P < 0.001), corresponding to a median increase of 26.8% (interquartile range: 14.4-50.1%). Antidiabetic medication was titrated up in 41.3%. In summary, among DPs, CHIKV infection has a significant negative impact on glycemic control and, compared with NDPs, results in greater morbidity. Close clinical and glycemic observation is recommended in DPs with CHIKV infection.
