We report a case of a 46-year-old Chinese male who presented with six months history of abdominal pain, weight loss and rectal bleeding. Diagnostic colonoscopy revealed multiple aphthous ulcers within the ileo-caecal region and distal transverse colon, separated by normal mucosa, mimicking skip lesions of Crohn's colitis. Computer topography (CT) scan of the abdomen showed multiple circumferential thickenings involving predominantly the right colon. A clinical diagnosis of colonic Crohn's disease with possible perforation was made. An extended right hemicolectomy was performed due to uncontrolled rectal bleeding. Histopath...

Introduction: Inflammatory bowel disease (IBD) and hidradenitis suppurativa (HS) are both chronic inflammatory diseases with a big impact in the quality of life of the patients. It has been described a higher prevalence of HS among patients diagnosed with IBD, especially Crohn disease. Some drugs used in HS, such as antibiotics, can be harmful for IBD patients and they may trigger flare ups. Adalimumab is anti-TNF drug which is approved for the treatment of both diseases, being the doses similar in both disorders.

Background: The pathogenesis of psoriasis may involve a breakdown of immune tolerance to cutaneous microorganisms. Guttate and chronic plaque psoriasis are associated with Streptococcus pyogenes colonization. In addition, Crohn disease and periodontitis, two diseases due to immune activation in response to microbiota, have been reported at a higher incidence in patients with psoriasis.

Pyoderma gangrenosum (PG) is a sterile, idiopathic, ulcerative, neutrophilic dermatosis that can be associated with trauma or systemic diseases. The lesion typically begins as a pustule that later progresses to an ulcer or deep erosion with violaceous undermined borders. Diagnosis of PG is based on histopathology as well as exclusion of other diagnoses. Approximately 50% of PG cases are associated with systemic diseases, which include inflammatory bowel disease (IBD), rheumatoid arthritis, and hematologic malignancies.

Study objectives: Many patients with psoriasis (PSO) experience comorbidities such as psoriatic arthritis, cardiovascular disease, inflammatory bowel disease and depression, which can make treatment and management challenging. We assessed whether an online, virtual patient simulation (VPS) activity could improve the competence of dermatologists in managing patients with PSO and comorbidities.

The objective of this study is to describe the epidemiological trend of PG patients in a university-based wound care outpatient center, focusing on demographics, comorbidities, and treatments.

We present a 24 year old female with a 4 year history of hidradenitis suppurativa (HS) and nodulocystic acne who developed vitiligo 4 mon ths after commencing adalimumab. Anti TNF therapy has been successfully used in other diseases, where the development of vitiligo has been noted in case reports.

Introduction: Paradoxical psoriasiform reactions due to the use of anti-TNF form a clinical spectrum that requires a correct multidisciplinary approach. This is due to the fact that they often cause great functional impotence, especially palmoplantar pustulosis or severe forms of the scalp, being refractory to the treatments classically used. Ustekinumab, following its recent approval for the treatment of inflammatory bowel disease (IBD), may be a good therapeutic alternative for these patients.

In this study, we investigated the characteristics of Tfr cells in UC patients. We gated circulating Tfr cells as CD4+CXCR5+CD25+CD127− T cells, of which approximately 73% on average were Foxp3+. The circulating Tfh (CD4+CXCR5+CD25−) cells from control subjects and UC patients presented a comparable capacity to induce IgM production from naive B cells and to mediate class switching to IgG. Tfr cells significantly reduced Tfh-mediated B cell help in both healthy controls and UC patients in a concentration-dependent manner. However, the suppression capacity of Tfr cells was significantly lower in UC patients than...
