Background: In Latin America, there are scarce data on the epidemiology of DGBI. The Rome Foundation Global Epidemiology Study (RFGES) Internet survey included 26 countries, four from Latin America: Argentina, Brazil, Colombia, and Mexico, with a 40.3% prevalence of Rome IV DGBI. We aimed at comparing the prevalence of DGBI and associated factors among these countries. Methods: The frequency of DGBI by anatomical region, specific diagnoses, sex, age, diet, healthcare access, anxiety, depression, and HRQOL, were analyzed and compared. Results: Subjects included Argentina n = 2057, Brazil = 2004, Colombia = 2007, and Mexico = 2001. The most common DGBI were bowel (35.5%), gastroduodenal (11.9%), and anorectal (10.0%). Argentina had the highest prevalence of functional diarrhea (p = 0.006) and IBS‐D; Brazil, esophageal, gastroduodenal disorders, and functional dyspepsia; Mexico functional heartburn (all <0.001). Overall, DGBI were more common in women vs. men and decreased with age. Bowel disorders were more common in the 18–39 (46%) vs. 40–64‐year (39%) groups. Diet was also different between those with DGBI vs. those without with subtle differences between countries. Subjects endorsing criteria for esophageal, gastroduodenal, and anorectal disorders from Mexico, more commonly consulted physicians for bowel symptoms vs. those from Argentina, Brazil, and Colombia. General practitioners were the most frequently consulted, by Mexicans (50.42%) and Colombians (40.80%), followed by gastroenterologists. Anxiety and depression were more common in DGBI individuals in Argentina and Brazil vs. Mexico and Colombia, and they had lower HRQOL. Conclusions: The prevalence of upper and lower DGBI, as well as the burden of illness, psychological impact and HRQOL, differ between these Latin American countries. [ABSTRACT FROM AUTHOR]

A great variety of clinical and immunological features have been described in patients with the antiphospholipid syndrome (APS), but information on their prevalence and characteristics in Latin American mestizo patients with the primary APS is scarce. To analyze the prevalence and characteristics of the main clinical and immunological manifestations in a cohort of patients with primary APS of mestizo origin from Latin America and to compare them with the European white patients, clinical and serological characteristics of 100 patients with primary APS from Colombia, Mexico, and Ecuador were collected in a protocol form that was identical to that used to study the "Euro-Phospholipid" cohort. The cohort consisted of 92 female patients (92.0%) and eight (8.0%) male patients. They were all mestizos. The most common manifestations were deep vein thrombosis (DVT; 23.0%), livedo reticularis (18.0%), migraine (18.0%), and stroke (18.0%). The most common pregnancy morbidity was early pregnancy losses (54.1% of pregnancies). Several clinical manifestations were more prevalent in the Latin American mestizo than in the European patients (transient global amnesia, pulmonary microthrombosis, arthralgias, and early pregnancy losses) and vice-versa (DVT, stroke, pulmonary embolism, and thrombocytopenia). Latin American mestizo patients with primary APS have a wide variety of clinical and immunological manifestations with several differences in their prevalence in comparison with European white patients.
