Guselkumab in the Treatment of Concomitant Hidradenitis Suppurativa, Psoriasis, and Crohn's Disease.

CONCLUSION: Guselkumab represents a promising therapeutic option for recalcitrant HS patients with inflammatory comorbidities in which IL-23 plays a role. PMID: 31389737 [PubMed - as supplied by publisher]

Authors: Aleksiejczuk M, Gromotowicz-Poplawska A, Marcinczyk N, Przylipiak A, Chabielska E Abstract The local renin-angiotensin-aldosterone system (RAAS) is fully expressed in the human skin at the mRNA and protein level. Local RAAS is known to play a regulatory function in epidermal proliferation, wound healing, scarring, cutaneous heating adaptation, and aging. There are also some indications of its role in the regulation of hair growth and sebum secretion. Impaired wound healing, skin diseases associated with diabetes, cancer development, psoriasis, and scleroderma may be related to changes in skin RAAS activity...

Authors: Meditskou S, Grekou A, Toskas A, Papamitsou T, Miliaras D Abstract Pyloric type metaplasia (PYME) as evidence of chronic mucosal damage, is one of the main histopathological findings for diagnosing Crohn's Disease (CD) in terminal ileum biopsies, according to the latest guidelines but still frequently underdiagnosed in routine pathology. Foveolar metaplasia (FOME) changes in mucosa, another aspect of the chronic post -inflammatory Ulcer Associated Cell Lineage (UACL), have only been reported in a few cases. However, their clinical significance has not been investigated in depth except in pouchitis. The aim...

Changes in the intestinal lymphatic vascular system, such as lymphatic obstruction, are characteristic features of inflammatory bowel diseases. The lymphatic vasculature forms a conduit to enable resolution of inflammation; this process is driven by specialized endogenous proresolving mediators (SPMs). To evaluate contributions of lymphatic obstruction to intestinal inflammation and to study profiles of SPMs, we generated a novel animal model of lymphatic obstruction using African green monkeys.

Conclusions In this review, we collected all the information concerning the OMICs studies performed on HS patients aimed at unraveling the mechanisms at the basis of the disease or associated to clinical severity and/or the successful response to pharmacological treatment (including biological drugs). The general picture of the OMICs contribution in the context of HS is not so clear and/or rich of clinical useful information, since most of the studies focused only on one aspect (genome, transcriptome, or proteome) of the disease, enrolling small numbers of patients (this is quite limiting for the genetic studies) from di...

AbstractSB5 (Imraldi®) is a biosimilar of the reference anti-TNF monoclonal antibody adalimumab. It is approved for use in the following indications for which reference adalimumab is approved: rheumatoid arthritis (RA), juvenile idiopathic arthritis [polyarticular juvenile idiopathic arthritis (pJIA) and enthesitis-related arthritis (ERA)], axial spondyloarthritis [ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA)], psoriatic arthritis (PsA), psoriasis, pediatric plaque psoriasis, hidradenitis suppurativa (HS), Crohn ’s disease, pediatric Crohn’s disease, ulcerative colitis...

Anemia of inflammation has been associated with Crohns disease, rheumatoid arthritis, psoriasis, and other inflammatory diseases. The role of IL 6 and Hepcidin has been studied in these conditions and it has been shown that ferritin is a marker of inflammation rather than anemia in these patients. However, little is known in regards to anemia in Hidradenitis Suppurativa (HS). The purpose of this study was to evaluate the correlation between haemoglobin (HB) and acute phase proteins as markers of inflammation in patients with HS.

ConclusionIn patients with HS or psoriasis, the safety of adalimumab EW and EOW was comparable and consistent with the expected adalimumab AE profile. The safety of adalimumab EW dosing in patients with dermatologic conditions is supported by data comparing adalimumab EW and EOW dosing for Crohn ’s disease, ulcerative colitis, and rheumatoid arthritis.Trial NCT00918255, NCT01468207, NCT01468233, NCT00645814, NCT00077779, NCT00055497, NCT01070303, NCT00195715, NCT00348283, NCT00385736, NCT00408629, and NCT00573794.

Conclusions: Cutaneous herpetic eruptions can evoke a predominantly folliculocentric mononuclear cell reaction and vasculitis; there is an association with underlying endogenous and/or iatrogenic immune dysregulation. Most cases are secondary to reactivation of varicella zoster. The histomorphology suggests a role for cell-mediated immunity. Antigenic homology of an endogenous 72-kd heat shock protein in follicles with that of a herpetic heat shock protein, in concert with an intrafollicular proliferative response of γ-δ T lymphocytes, may explain the follicular localization and composition of the infiltrate.
