Objectives: 1) To determine the prevalence of increased number of eosinophils in colonic mucosa of patients with lymphocytic colitis (LC). 2) To determine the coexistence of eosinophilic colitis (EC) in patients with lymphocytic colitis.
Materials And Methods: slides of adult patients with cronic diarrhea with diagnosis of LC were reviewed between October 2009 and March 2012. The number of eosinophils was quantified.
Results: Sixty eight patients with LC were included. Elevated eosinophils were found in 76.5 and in 51.4% a diagnosis of EC was established.
Conclusion: 3 out of 4 patients with LC had elevated eosinophils and 1 of 2 patients with LC had criteria for EC.

DIAGNOSIS AND TREATMENT OF MICROSCOPIC COLITIS: POSITION PAPER ON BEHALF OF THE BRAZILIAN FEDERATION OF GASTROENTEROLOGY.
Arq Gastroenterol
January 2025
Universidade de Campinas, Departamento de Gastroenterologia, Campinas, SP, Brasil.
Background: Microscopic colitis (MC) is a chronic inflammatory condition of the colon, primarily characterized by watery diarrhea, with normal or near-normal endoscopic findings. It encompasses two main subtypes: lymphocytic colitis and collagenous colitis.
Objective: This position paper from the Brazilian Federation of Gastroenterology aims to review current evidence on the diagnosis and management of MC in Brazil, emphasizing the need for standardization across the country's healthcare systems.

Article Synopsis
- Microscopic colitis (MC) is a significant but often overlooked cause of chronic diarrhea, especially when colonoscopy results appear normal, prompting the need for more thorough diagnostic methods.
- A study involving 116 patients showed that 32.8% were diagnosed with MC, with lymphocytic colitis being more prevalent, and elevated inflammatory markers like fecal calprotectin, ESR, and CRP were linked to MC.
- Symptoms such as nocturnal diarrhea and abdominal pain were strongly associated with MC, and specific cutoff values for inflammatory markers demonstrated high accuracy for diagnosis, indicating the necessity for further exploration and validation in future research.

Background: Microscopic colitis is a relatively new diagnosis that was first described in the 1980s. Patients usually present with chronic watery and non-bloody diarrhea and are typically characterized by an unremarkable gross appearance of the colon on lower endoscopy while having evidence of lymphocytic infiltration of the lamina propria and the epithelium on histology. Two subtypes have been described in the literature: Collagenous colitis, with marked thickening of the subepithelial layer, and Lymphocytic colitis.

Article Synopsis
- The paper aims to increase awareness of microscopic colitis (MC), a chronic inflammatory bowel disease, focusing on its recognition, risk factors, diagnosis, management, and complications.
- MC is characterized by nonspecific symptoms like watery diarrhea, which makes diagnosis challenging, and the average onset age is around 62-65 years, with women being more affected.
- Risk factors for MC include lifestyle factors like smoking and alcohol consumption, various medications, and other health conditions; treatment typically involves budesonide or other therapies tailored to individual cases.
Rapid identification of primary atopic disorders (PAD) by a clinical landmark-guided, upfront use of genomic sequencing.

Article Synopsis
- Primary atopic disorders (PAD) are rare genetic conditions caused by specific gene variants that affect skin and immune function, making diagnosis challenging among common allergic disease cases.
- Identifying PAD requires recognizing clinical red flags like family history and unusual infections, as conventional lab tests are inadequate for definitive diagnosis.
- Whole-genome sequencing (WGS) enhances diagnostic efficiency and accuracy, but requires careful interpretation and collaboration among specialists to effectively manage PAD cases.
