Abstract

Background:

Inflammatory bowel diseases (IBD) incidence and prevalence in Latin America have experienced a significant shift in the last decades. There is paucity of IBD epidemiologic data in Argentina.

Aim:

To determine the incidence and prevalence of IBD between 2018 and 2022 of a population from the city of Buenos Aires.

Materials And Methods:

From January 1st, 2018 to December 31st, 2022, the total population of two healthcare insurances were studied. 'Possible' IBD cases were identified using the following information sources: IBD-unit patient databases; electronic medical record; central laboratory electronic database; histopathology electronic database; pharmacy electronic database. Age-adjusted incidence and prevalence rates for Crohn's disease (CD), ulcerative colitis (UC) and IBD were estimated based on the number of patients compared with the at-risk population and expressed per 100,000 subjects. Trends in IBD incidence and prevalence were estimated as annual percentage changes; we used Poisson regression modeling to calculate significance in these trends over time.

Results:

Information source analysis rendered 172 possible cases, of which 82 cases of IBD were finally confirmed: 27.16% were CD and 72.84% were UC. Mean age-standardized incidence across the study period for IBD, CD and UC was 11.93 (11.28-12.55), 2.88 (2.65-3.07) and 9.05 (8.83-9.2) respectively. Point prevalence on December 31st, 2022 for IBD, UC and CD was 134 (95%CI 132.3-135.6), 98 (96.95-99.52) and 36 (35.69-36.4) respectively.

Conclusions:

We found an incidence and prevalence of IBD in a population from Buenos Aires higher than those previously published in epidemiological studies in Argentina.

Inflammatory Bowel Disease II: Crohn's Disease

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Ulcerative Colitis

Inflammatory Bowel Disease I: Ulcerative Colitis

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Chronic Bowel Disorders: Introduction

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Prevalence and Incidence

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Inflammatory Bowel Disease IV: Pharmacological Management

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
Pharmacologic...
