RESUMO

BACKGROUND: Celiac disease (CeD) is an immune-mediated disorder affecting the small bowel, associated with genetic factors and increasing global prevalence. AIM: This study explores the association between CeD, Systemic Lupus Erythematosus (SLE), primary Sjogren syndrome (pSS), and Systemic Sclerosis (SSc). METHODS: A systematic review and meta-analysis were conducted following PRISMA guidelines. Searches across multiple databases yielded 2728 articles, with 15 studies selected. Data extraction included study characteristics, prevalence of CeD and CeD antibodies in SLE, pSS, and SSc. Quality assessment utilized the Newcastle-Ottawa Scale. RESULTS: The meta-analysis revealed a pooled prevalence of biopsy-proven CeD in SLE, pSS, and SSc of approximately 3%. Seroprevalence of any CeD antibody in SLE, pSS, and SSc ranged from 3% to 10%. Notably, pSS exhibited the highest prevalence at 5.59%. High heterogeneity was observed in seroprevalence across autoimmune conditions. Quality assessment indicated robust methodological quality in the selected studies. CONCLUSION: This study highlights a significantly higher prevalence of CeD, especially pSS, compared to the general population. The findings underscore the importance of recognizing elevated CeD antibodies in patients with SLE, pSS and SSc emphasizing the need for early detection and comprehensive care for gastrointestinal symptoms in these conditions.

RESUMO

The significant global burden of colorectal cancer accentuates disparities in access to preventive healthcare in most low- and middle-income countries (LMICs) as well as large sections of underserved populations within high-income countries. The barriers to colorectal cancer screening in economically transitioning Latin America are multiple. At the same time, immigration from these countries to the USA continues to increase. This case highlights the delays in diagnosis experienced by a recent immigrant from a country with no established colorectal cancer screening program, to an immigrant population in the USA with similar poor screening coverage. We discuss common challenges faced by Latinos in their home countries and the USA, as well as strategies that could be implemented to improve screening coverage in US immigrant populations.

RESUMO

Importance: Colorectal cancer (CRC) is a leading cause of cancer-related mortality globally, with increasing incidence and mortality in Latin America. CRC screening programs can reduce disease burden, but information on screening programs in Latin America is limited. Objective: To describe characteristics (eg, type of program, uptake, neoplastic yield) of CRC screening programs in Latin America. Data Sources: PubMed, Ovid MEDLINE, EMBASE, Cochrane, PsycINFO, Web of Science Core Collection, LILACS, and SciELO were searched from inception to February 2023. Relevant references from bibliographies, conference proceedings, and gray literature were considered. The search strategy included English, Spanish, and Portuguese terms. Study Selection: Included were studies of CRC screening programs in Latin America using fecal immunochemical test (FIT) or colonoscopy as the primary screening method. Four reviewers independently assessed study eligibility based on titles, with review of abstracts and full texts as needed. Data Extraction and Synthesis: Guidelines from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were followed for data abstraction and quality assessment. Descriptive information was extracted, and data were pooled using a random-effects model. Main outcomes and Measures: Program performance indicators included rates of participation and FIT positivity, adenoma detection rate (ADR), advanced adenoma detection rate (AADR), CRC detection rate, and colonoscopy quality indicators. Results: There were 17 studies included from upper middle-income and high-income countries in Latin America with a total of 123 929 participants. Thirteen studies used FIT as the initial screening method, whereas 4 used screening colonoscopy. The participation rate in FIT-based programs was 85.8% (95% CI, 78.5%-91.4%). FIT positivity rates were 15.2% (95% CI, 9.6%-21.8%) for the 50-ng/mL threshold and 9.7% (95% CI, 6.8%-13.0%) for the 100-ng/mL threshold. For FIT-based studies, the pooled ADR was 39.0% (95% CI, 29.3%-49.2%) and CRC detection rate was 4.9% (95% CI, 2.6%-7.9%); for screening colonoscopy-based studies, the pooled ADR was 19.9% (95% CI, 15.5%-24.8%) and CRC detection rate was 0.4% (95% CI, 0.1%-0.8%). Conclusions and Relevance: This systematic review and meta-analysis suggests that CRC screening in upper middle-income countries in Latin America is feasible, detecting rates of neoplasia comparable with those of high-income regions. Population-based screening programs should be developed or enhanced in these settings. There is a knowledge gap regarding feasibility and yield of screening programs in lower middle-income countries.

RESUMO

Background: The COVID-19 pandemic has had a severe impact on the Latin American subcontinent, particularly in areas with limited hospital resources and a restricted Intensive Care Unit (ICU) capacity. This study aimed to provide a comprehensive description of the clinical characteristics, outcomes, and factors associated with survival of COVID-19 hospitalized patients in Honduras. Research question: What were the characteristics and outcomes of COVID-19 patients in a large referral center in Honduras? Study design and methods: This study employed a retrospective cohort design conducted in a single center in San Pedro Sula, Honduras, between October 2020 to March 2021. All hospitalized cases of confirmed COVID-19 during this timeframe were included in the analysis. Univariable and multivariable survival analysis were performed using Kaplan-Meier curves and Cox proportional hazards model aiming to identify factors associated with decreased 30 day in-hospital survival, using a priori-selected factors. Results: A total of 929 confirmed cases were identified in this cohort, with males accounting for 55.4 % of cases. The case fatality rate among the hospitalized patients was found to be 50.1 % corresponding to 466 deaths. Patients with comorbidities such as hypertension, diabetes, obesity, chronic kidney disease, chronic obstructive pulmonary disease and cardiovascular disease had a higher likelihood of mortality. Additionally, non-survivors had a significantly longer time from illness onset to hospital admission compared to survivors (8.2 days vs 4.7 days). Among the cohort, 306 patients (32.9 %) met criteria for ICU admission. However, due to limited capacity, only 60 patients (19·6 %) were admitted to the ICU. Importantly, patients that were unable to receive level-appropriate care had lower likelihood of survival compared to those who received level-appropriate care (hazard ratio: 1.84). Interpretation: This study represents, the largest investigation of in-hospital COVID-19 cases in Honduras and Central America. The findings highlight a substantial case fatality rate among hospitalized patients. In this study, patients who couldn't receive level-appropriate care (ICU admission) had a significantly lower likelihood of survival when compared to those who did. These results underscore the significant impact of healthcare access during the pandemic, particularly in low- and middle-income countries.

RESUMO

Biomass cookstove food preparation is linked to aero-digestive cancers, mediated by ingested and inhaled carcinogens (e.g., heterocyclic amines, and polycyclic aromatic hydrocarbons). We investigated the association between gastric adenocarcinoma, wood cookstove use, H. pylori CagA infection and risk modification by variants in genes that metabolize and affect the internal dose of carcinogens. We conducted a population-based, case-control study (814 incident cases, 1049 controls) in rural Honduras, a high-incidence region with a homogeneous diet and endemic H. pylori infection, primarily with the high-risk CagA genotype. We investigated factors including wood cookstove use, H. pylori CagA serostatus, and 15 variants from 7 metabolizing genes, and the interactions between wood stove use and the genetic variants. Male sex (OR 2.0, 1.6-2.6), age (OR 1.04, 1.03-1.05), wood cookstove use (OR 2.3, 1.6-3.3), and CagA serostatus (OR 3.5, 2.4-5.1) and two SNPs in CYP1B1 (rs1800440 and rs1056836) were independently associated with gastric cancer in multivariate analysis. In the final multivariate model, a highly significant interaction (OR 3.1, 1.2-7.8) was noted between wood cookstove use and the rs1800440 metabolizing genotype, highlighting an important gene-environment interaction. Lifetime wood cookstove use associates with gastric cancer risk in the high-incidence regions of Central America, and the association is dependent on the rs1800440 genotype in CYP1B1. H. pylori CagA infection, wood cookstove use and the rs1800440 genotype, all of which are highly prevalent, informs who is at greatest risk from biomass cookstove use.

RESUMO

INTRODUCTION: Peptic ulcers with adherent clots are associated with a high-risk of rebleeding and mortality. However, the optimal management of bleeding ulcers with adherent clots remains unclear. We conducted this systematic review and meta-analysis to compare endoscopic therapy and conservative therapy to manage bleeding ulcers with adherent clots. METHODS: We systematically searched PubMed, Embase, and Web of Science databases through October 2022 to include all studies comparing the endoscopic and conservative therapeutic approaches for bleeding ulcers with adherent clots. Our primary outcome was rebleeding (overall and 30-day). The secondary outcomes were mortality (overall and 30-day), need for surgery, and length of hospital stay (LOS). The random-effects model was used to calculate the pooled odds ratios (OR) and mean differences (MD) with the corresponding confidence intervals (CI) for proportional and continuous variables, respectively. RESULTS: Eleven studies (9 RCTs) with 833 patients (431 received endoscopic therapy vs. 402 received conservative therapy) were included. Overall, endoscopic therapy was associated with lower overall rebleeding (OR 0.41, 95% CI 0.22-0.79, P = 0.007), 30-day rebleeding (OR 0.43, 95% CI 0.21-0.89, P = 0.002), overall mortality (OR 0.47, 95% CI 0.23-0.95, P = 0.04), 30-day mortality (OR 0.43, 95% CI 0.21-0.89, P = 0.002), need for surgery (OR 0.44, 95% CI 0.21-0.95, P = 0.04), and LOS (MD - 3.17 days, 95% CI - 4.14, - 2.19, P < 0.00001). However, subgroup analysis of randomized controlled trials (RCTs) showed no significant difference in overall mortality (OR 0.78, 95% CI 0.24-2.52, P = 0.68) between the two strategies, with numerically lower but statistically non-significant rates of overall rebleeding (7.2% vs. 18.5%, respectively; OR 0.42, 95% CI 0.17-1.05, P = 0.06), statistically lower rate of need for surgery (OR 0.28, 95% CI 0.08-0.96, P = 0.04) with endoscopic therapy compared to conservative therapy. CONCLUSIONS: Our meta-analysis demonstrates that endoscopic therapy was overall associated with lower rates of rebleeding (overall and 30-day), mortality (overall and 30-day), need for surgery, and LOS, compared to conservative therapy for the management of bleeding ulcers with adherent clots. However, subgroup analysis of RCTs showed that endoscopic therapy was associated with numerically lower but statistically non-significant rates of overall rebleeding and a statistically lower rate of need for surgery compared to conservative therapy with similar overall mortality rates. Combined treatment with thermal therapy and injection therapy was the most effective treatment modality in reducing rebleeding risk. Further large-scale RCTs are needed to validate our findings.

RESUMO

The internet has become a necessary communication platform for health information. The quality of online material for patients varies significantly, and this is not different for material on gastrointestinal cancers. We aimed to assess English and Spanish online patient information addressing esophageal, gastric, and colorectal cancer treatment. Six independent Google searches were conducted using the terms: esophageal cancer treatment, gastric cancer treatment, colorectal cancer treatment, and their translations in Spanish. Websites were included in the top 50 results for each search. Readability was assessed using two validated tests for each language. Understandability/actionability, quality, and cultural sensitivity were assessed using Patient Education Materials Assessment Tool (PEMAT), DISCERN, and Cultural Sensitivity Assessment Tool (CSAT), respectively. Pearson's chi-squared was used for categorical variables and Wilcoxon rank-sum (2 groups) or Kruskal-Wallis (> 2 groups) for continuous. One hundred twelve websites were analyzed. Readability levels were high in both languages (between 11th grade and university level) and significantly higher in English. Mean quality scores for English and Spanish were consistent with good quality. CSAT scores met the cultural acceptability with lower CSAT scores for gastric cancer treatment in English. Higher actionability scores were found in English for colorectal cancer. Also, there was a clear trend for higher cultural sensitivity and quality of Spanish material for gastric cancer treatment. Online patient information on esophageal, gastric, and colorectal cancer treatment, in English and Spanish, were at a readability level above the average literacy level and even significantly higher in English. Initiatives to improve online information on gastrointestinal cancer treatments are warranted.

RESUMO

Background: Lumen-apposing metal stents (LAMSs) are often used to drain pancreatic fluid collections (PFCs). However, adverse events, such as stent obstruction, infection, or bleeding, have been reported. Concurrent double-pigtail plastic stent (DPPS) deployment has been suggested to prevent these adverse events. This meta-analysis aimed to compare the clinical outcomes of LAMS with DPPS vs. LAMS alone in the drainage of PFCs. Methods: An extensive search was conducted in the literature to include all the eligible studies that compared LAMS with DPPS vs. LAMS alone for drainage of PFCs. Pooled risk ratios (RRs) with the 95% confidence intervals (CIs) were obtained within a random-effect model. The outcomes were technical and clinical success, and overall adverse events, including stent migration and occlusion, bleeding, infection, and perforation. Results: Five studies involving 281 patients with PFCs (137 received LAMS plus DPPS vs. 144 received LAMS alone) were included. LAMS plus DPPS group was associated with comparable technical success (RR: 1.01, 95% CI: 0.97 - 1.04, P = 0.70) and clinical success (RR: 1.01, 95% CI: 0.88 - 1.17). Lower trends of overall adverse events (RR: 0.64, 95% CI: 0.32 - 1.29), stent occlusion (RR: 0.63, 95% CI: 0.27 - 1.49), infection (RR: 0.50, 95% CI: 0.15 - 1.64), and perforation (RR: 0.42, 95% CI: 0.06 - 2.78) were observed in LAMS with DPPS group compared to LAMS alone but without a statistical significance. Stent migration (RR: 1.29, 95% CI: 0.50 - 3.34) and bleeding (RR: 0.65, 95% CI: 0.25 - 1.72) were similar between the two groups. Conclusions: Deployment of DPPS across LAMS for drainage of PFCs has no significant impact on efficacy or safety outcomes. Randomized, controlled trials are necessary to confirm our study results, especially in walled-off pancreatic necrosis.

RESUMO

Aim: We performed a systematic review and meta-analysis to identify the prevalence of small intestinal bacterial overgrowth (SIBO) in patients with gastroparesis. Background: Several studies have suggested an association between SIBO and gastroparesis, which is characterized by delayed gastric emptying in the absence of mechanical obstruction. Methods: A comprehensive search was performed using MEDLINE, EMBASE, Scopus and Cochrane Central Register of Controlled Trials (CENTRAL) through January, 2022 for randomized controlled trials and observational studies reporting the prevalence of SIBO in gastroparesis. Pooled prevalence was estimated using a random effects model. Heterogeneity was assessed by using the inconsistency index (I2). Results: Among the 976 articles identified, 43 studies were selected for full text review. Six studies, with 385 patients, were deemed eligible for inclusion, with a perfect agreement between investigators (kappa=1.0). Overall, 379 patients were diagnosed with gastroparesis by gastric emptying scintigraphy and six were diagnosed with a wireless motility capsule. The pooled prevalence of SIBO was 41% (95% confidence interval 0.23-0.58). SIBO was diagnosed using jejunal aspirate cultures (N=15, 8.4%), lactulose breath test (N=80, 44.7%), glucose breath test (N=30, 16.8%), D-xylose breath test (N=52, 29.1%), and hydrogen breath test (N=2, 1.1%). Heterogeneity was significant and noted to be high at 91%. Only one study reported SIBO diagnosis in controls, therefore no pooled odds ratio was calculated. Conclusion: SIBO was present in almost half of the patients with gastroparesis. Future studies should examine and identify the association between SIBO and gastroparesis.

RESUMO

To compare the clinical outcomes of a low dose dexamethasone strategy vs. a high-dose dexamethasone strategy in hypoxemic COVID-19 patients. A retrospective observational study comparing low-dose (8 mg) and high-dose dexamethasone (24 mg) of COVID-19 patients admitted from September 1, 2020 to October 31, 2020 in a hospital in Honduras. We included 81 patients with confirmed COVID-19 who required oxygen therapy. The mean age was similar between groups (57.49 vs. 56.95 years). There were more male patients in the group of 24 mg ( p = 0.01). Besides, patients on the 24 mg dose had more prevalence of hypertension ( p = 0.052). More patients in the 24 mg group had a higher rate of invasive mechanical ventilation (15.00% vs. 2.56%, p = 0.058). When evaluating the association between the high dose group and outcomes, we find no significant association with mortality, nosocomial infections, high flow mask, invasive mechanical ventilation, or the need for vasopressors. We find no significant differences in the Kaplan-Meier analysis regarding the survival (log-rank p -value = 0.315). We did not find significant differences between the use of 24 mg and 8 mg of dexamethasone in hypoxemic COVID-19 patients.

RESUMO

Overlap syndrome (OS) is a term that comprises the presentation of multiple hepatic disease characteristics in the same patient, such as the presence of autoimmune hepatitis (AIH) features in addition to primary sclerosing cholangitis (PSC) or primary biliary cholangitis (PBC). Standard therapy for AIH is immunosuppression, while ursodeoxycholic acid is the preferred treatment for PBC. Additionally, liver transplantation (LT) may be considered in severe cases. Hispanics have been found to have a higher prevalence of chronic liver disease and develop more complications associated with portal hypertension at the time of listing for LT. Despite being the fastest-growing population in the USA, Hispanics have a higher probability of not receiving an LT due to issues with social determinants of health (SDOH). It has been reported that Hispanics are more likely to be removed from the transplant list. We report a case of a 25-year-old female immigrant from a Latin American developing country who presented with symptoms consistent with worsening liver disease after years of inappropriate workup and late diagnosis due to barriers within the healthcare system. The patient had a history of unresolved jaundice and pruritus and presented with worsening of her previous symptoms and new onset abdominal distention, bilateral leg edema, and telangiectasias. Laboratory and imaging studies confirmed the diagnosis of AIH and primary sclerosing cholangitis (PSC-AIH syndrome). The patient was started on steroids, azathioprine, and ursodeoxycholic acid, showing improvement. Due to her migratory status, she could not receive an appropriate diagnosis and follow up with a single provider or healthcare institution, putting her at increased risk for life-threatening complications. Although medical management is the first step, the probability of future liver transplants exists. The patient is still undergoing liver transplant evaluation and completing a workup since she was found to have an elevated model for end-stage liver disease (MELD) score. Even with the introduction of new scores and policies that aim to reduce disparities in LT, Hispanic patients are still at higher risk of being removed from the waitlist because of death or clinical deterioration compared to non-Hispanics. To this day, Hispanics have the highest percentage of waitlist deaths (20.8%) of all ethnicities and the lowest overall rate for undergoing LT. Understanding and addressing the causes that could contribute to and explain this phenomenon is essential. Increasing awareness of this problem is vital to promote more research on LT disparities.

RESUMO

INTRODUCTION: Chronic Pancreatitis (CP) is a fibroinflammatory condition with debilitating symptoms. Quality of life is severely affected in patients with CP and they are likely to suffer from mental health disorders, including depression. We conducted a systematic review and meta-analysis assessing the prevalence of depressive symptoms and depression in patients with CP. METHODS: MEDLINE (OVID), PsycINFO, Cochrane Library, Embase, CINAHL Complete, Scopus and Web of Science were searched until July 2022 to identify manuscripts reporting the prevalence of depressive symptoms and depression (diagnosed clinically or with a validated scale without language restriction) in patients with Chronic Pancreatitis. The pooled prevalence was calculated using a random effects model. Heterogeneity was assessed by the inconsistency index (I2). RESULTS: Among 3647 articles identified, 58 studies were identified for full text review, and ultimately nine studies were included. A total of 87,136 patients were included in the studies. Depression was diagnosed clinically or symptoms were identified using validated scales including Center for Epidemiological Studies 10-item Depression Scale (CESD), Beck Depression Inventory (BDI) and Hospital Anxiety and Depression Scale (HADS). The overall prevalence of depression in patients with chronic pancreatitis was 36.2% (95%CI: 18.8-55.7). In the stratified analysis, depression prevalence according to the clinical diagnosis, BDI and HADS was 30.10%, 48.17% and 36.61%, respectively. CONCLUSION: The high prevalence of depression among patients with CP deserves a call-to-action due to its medical implications and worsening quality of life. Our findings raise awareness of the importance of screening patients with CP for mental health disorders. Further well-designed studies are needed to further characterize these findings.

RESUMO

We describe the case of a 51-year-old man who presented with a palpable purpuric rash and associated four days of lower gastrointestinal bleeding one month after testing positive for COVID-19. Urine studies showed evidence of microscopic hematuria and an increased protein/creatinine ratio. An abdominal computed tomography scan showed distal ileitis, and a skin biopsy was significant for IgA vasculitis. Treatment with methylprednisolone was started, which led to the resolution of symptoms. Immunologic consequences of COVID-19 must not be overlooked, as they have a wide variety of presentations in diverse aged populations. IgA vasculitis is uncommon in adults, as well as gastrointestinal bleeding as a complication related to COVID-19.

RESUMO

Gastric adenocarcinoma (GC) is the fourth leading cause of global cancer mortality, and the leading infection-associated cancer. Helicobacter pylori is the dominant risk factor for GC and classified as an IARC class I carcinogen. Surveillance of gastric premalignant conditions is now indicated in high-risk patients. Upper endoscopy is the gold standard for GC diagnosis, and image-enhanced endoscopy increases the detection of gastric premalignant conditions and early gastric cancer (EGC). Clinical staging is crucial for treatment approach, defining early gastric cancer, operable locoregional disease, and advanced GC. Endoscopic submucosal dissection is the treatment of choice for most EGC. Targeted therapies are rapidly evolving, based on biomarkers including MSI/dMMR, HER2, and PD-L1. These advancements in surveillance, diagnostic and therapeutic strategies are expected to improve GC survival rates in the near term.

RESUMO

Drug Reaction with Eosinophilia and Systemic Response (DRESS) syndrome is a rare hypersensitivity reaction characterized by rash, fever, lymphadenopathy, and visceral involvement. The liver is frequently involved in DRESS, with increased liver enzymes and hepatomegaly. Over 40 drugs have been implicated in the induction of DRESS, however other illicit substances have also been linked to this. Prompt identification of this syndrome is imperative for management. We report the case of patient presenting with acute liver injury and eosinophilia, who developed a rash meeting criterion for DRESS, with Cocaine as the suspected culprit agent, and was successfully treated with conservative measures.

RESUMO

We report a case of an 81-year-old male immigrant from a Latin American developing country with a high burden of upper gastrointestinal neoplasms, who presented with a small bowel gastrointestinal stromal tumor (GIST) after 2 years of delay in the diagnosis due to multiple barriers to healthcare. The patient presented with a partial intestinal obstruction in an abdominal computed tomography (CT) scan suggestive of a GIST. Surgical resection was performed, and adjuvant therapy was initiated with imatinib (a tyrosine kinase inhibitor) after the diagnosis was confirmed. The patient had a successful outcome. Due to his migratory status, the patient planned to follow up with different health providers in two different countries, which constitutes a common challenge in the immigrant population.

RESUMO

PURPOSE: Population-based cancer registries (PBCRs) are critical for national cancer control planning, yet few low- and middle-income countries (LMICs) have quality PBCRs. The Central America Four region represents the principal LMIC region in the Western hemisphere. We describe the establishment of a PBCR in rural Western Honduras with first estimates for the 2013-2017 period. METHODS: The Western Honduras PBCR was established through a collaboration of academic institutions and the Honduras Ministry of Health for collection of incident cancer data from public and private health services. Data were recorded using the Research Electronic Data Capture (REDCap) web-based platform with data monitoring and quality checks. Crude and age-standardized rates (ASRs) were calculated at the regional level, following WHO methodology. RESULTS: The web-based platform for data collection, available ancillary data services (eg, endoscopy), and technical support from international centers (United States and Colombia) were instrumental for quality control. Crude cancer incidence rates were 112.2, 69.8, and 154.6 per 100,000 habitants overall, males, and females, respectively (excluding nonmelanoma skin cancer). The adjusted ASRs were 84.2, 49.6, and 118.9 per 100,000 overall habitants, males, and females, respectively. The most common sites among men were stomach (ASR 26.0, 52.4%), colorectal (ASR 5.11, 10.15%), and prostate (ASR 2.7, 5.4%). The most common sites in women were cervix (ASR 34.2, 36.7%), breast (ASR 11.2, 12.3%), and stomach (ASR 10.8, 11.7%). CONCLUSION: The Copán-PBCR represents a successful model to develop cancer monitoring in rural LMICs. Innovations included the use of the REDCap platform and leverage of Health Ministry resources. This provides the first PBCR data for Honduras and the Central America Four and confirms that infection-driven cancers, such as gastric and cervical, should be priority targets for cancer control initiatives.

RESUMO

Cardiovascular Disease (CVD) epidemiology varies significantly among Low and Middle-Income Countries. Honduras is the Central American country with the highest Ischemic Heart Disease and CVD mortality rates. The aim of this study was to assess the individual CVD risk factors and calculate Cardiovascular Risk Assessment Scores (CVRAS) from the population. Methods: A cross-sectional study in western Honduras. Estimation of CV risk was performed using Framingham, MESA, ACC/AHA-PCEs and ESC SCORE calculators. Results: 38% were male. For men and women respectively; 49% and 48% had self-reported hypertension (HTN), on measured blood pressure only 18% and 30% had normal readings. Diabetes Mellitus was reported in 19% and 22%. Tobacco use was 14% and 3%. Self-reported regular exercise was 39.9% and 25%. Obesity was diagnosed in 24% and 24%. Lipid profile; total cholesterol was ≥200 mg/dl in 63% of subjects. LDL-C was elevated (>100 mg/dl) in 74% of participants, 9% had LDL-C levels higher than 190 mg/dl. Triglycerides were high (>160 mg/dl) in 60%, of these subjects 22% were taking lipid-lowering medications. 52% reported family-history of CVD. The risk calculation for men and women respectively for each CVRAS were; AHA/ACC-PCEs high risk (score ≥ 7.5%) in 62% and 30%, FRS high risk (score ≥ 20%) 46% and 15%, MESA high risk (Score ≥ 7.5%) in 70.6% and 17.7%, ESC SCORE high risk (score ≥ 5% in 32.4% and 11.8%). Conclusions: CV risk calculations revealed higher than rates than expected with consequently reflected on higher than estimated CVRAS. This represents the first report of its kind in Honduras.

RESUMO

BACKGROUND: Antimicrobial resistance is a global public health problem, particularly in low- and middle-income countries (LMICs), where antibiotics are often obtained without a prescription. H. pylori antimicrobial resistance patterns are informative for patient care and gastric cancer prevention programs, have been shown to correlate with general antimicrobial consumption, and may guide antimicrobial stewardship programs in LMICs. We report H. pylori resistance and antimicrobial utilization patterns for western Honduras, representative of rural Central America. METHODS: In the context of the western Honduras gastric cancer epidemiology initiative, gastric biopsies from 189 patients were studied for culture and resistance patterns. Antimicrobial utilization was investigated for common H. pylori treatment regimens from regional public (7 antimicrobials) and national private (4 antimicrobials) data, analyzed in accordance with WHO anatomical therapeutic chemical defined daily doses (DDD) method and expressed as DDD/1000 inhabitants per day (DID) and per year (DIY). RESULTS: H. pylori was successfully cultured from 116 patients (56% males, mean age: 54), and nearly all strains were cagA+ and vacAs1m1+ positive (99% and 90.4%, respectively). Unexpectedly, high resistance was noted for levofloxacin (20.9%) and amoxicillin (10.7%), while metronidazole (67.9%) and clarithromycin (11.2%) were similar to data from Latin America. Significant associations with age, gender, or histology were not noted, with the exception of levofloxacin (28%, P = 0.01) in those with histology limited to non-atrophic gastritis. Total antimicrobial usage in western Honduras of amoxicillin (17.3 DID) and the quinolones had the highest relative utilizations compared with other representative nations. CONCLUSIONS: We observed significant H. pylori resistance to amoxicillin and levofloxacin in the context of high community antimicrobial utilization. This has implications in Central America for H. pylori treatment guidelines as well as antimicrobial stewardship programs.
