RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Central nervous system (CNS) malformations, including neural tube defects (NTDs), are the second most common type of birth defects worldwide and are major causes of childhood disability and mortality. We report the first analysis of birth prevalence in Western Honduras of CNS malformations including NTDs over 6 consecutive years. METHODS: Data from all patients with congenital CNS malformations and total live births for the period 2010-2015 were obtained through institution and regional registries from all 3 public referral hospitals in Western Honduras, representing 67 municipalities. Cases were identified using the International Classification of Diseases, Tenth Revision CNS malformation codes. Birth prevalence was calculated as cases per 10,000 live births. RESULTS: From 123,903 live births, 275 cases of CNS malformations were identified (54% females, 58% NTDs). Six-year birth prevalence of CNS malformations was 13.9-31.1. Spina bifida variants and anencephaly represented 80% and 19% of reported NTDs, respectively. Total 6-year prevalence of NTDs in Western Honduras was 7.0-17.4 over years studied. In 6 municipalities, average prevalence was >30 (maximum 49.0). CONCLUSION: This is the first study reporting disease burden of CNS malformations in Western Honduras. The nationwide birth prevalence of NTDs in rural Honduras may have decreased since the implementation of prenatal health policies in 2005. However, we identified regions with unexpectedly elevated prevalence, indicating high regional prevalence that could be targeted for improved preventive efforts, ultimately decreasing the burden of these conditions.
