Neville JJ, Beattie RM, Stanton MP. The Diagnostic Utility of Lip Biopsy in Paediatric Crohn's Disease: A 10-year Single-centre Retrospective Study. J Pediatr Surg 2024; 59:258-260. [PMID: 37951733 DOI: 10.1016/j.jpedsurg.2023.10.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 10/11/2023] [Indexed: 11/14/2023]
Abstract
BACKGROUND Oral manifestations of paediatric Crohn's disease (CD) are reported in up to 60% of cases. Lip biopsy can be used to histologically diagnose oral CD. We evaluated the utility of lip biopsy in children under initial investigation for potential CD. METHODS A 10-year retrospective review of electronic patient records at a single tertiary paediatric surgery centre was performed. All patients aged ≤16 years who underwent lip biopsy were included. Clinical features, histology, and diagnostic details were extracted. RESULTS Forty-two children underwent lip biopsy. Median age at biopsy was 13.3 years (11.0-14.9). Final diagnosis was CD in 21/42 (50%) children, indeterminant colitis in 3/42 (7%), orofacial granulomatosis (OFG) in 3/42 (7%), coeliac disease in 1/42 (2%), and eosinophilic oesophagitis in 1/42 (2%). Thirteen children (31%) received no formal diagnosis. The most common symptoms reported were oral ulceration (33/42, 79%), lip swelling (21/42, 50%), and abdominal pain (19/42, 45%). Lip biopsy histology was normal in 11/42 (26%). In 24/42 (57%), non-granulomatous inflammation was seen. In 7/42 (17%) lip biopsy identified granulomatous inflammation: three (7%) had endoscopic biopsies concordant for CD, three (7%) had negative endoscopic biopsies but were diagnosed with CD, and one was diagnosed with OFG (2%). Sensitivity was 29% and specificity was 95%. CONCLUSION Lip biopsy has low sensitivity but high specificity for diagnosing CD. Lip biopsy diagnosed CD in 7% when endoscopic biopsies were negative, enabling treatment. LB is a useful diagnostic test for CD in children presenting with oral symptoms. LEVEL OF EVIDENCE III.

Abstract
Granulomatous inflammation (GI) diseases are a group of chronic inflammation disorders characterized by focal collections of multinucleated giant cells, epithelioid cells and macrophages, with or without necrosis. GI diseases are closely related to microbes, especially virulent intracellular bacterial infections are important factors in the progression of these diseases. They employ a range of strategies to survive the stresses imposed upon them and persist in host cells, becoming the initiator of the fighting. Microbe-host communication is essential to maintain functions of a healthy host, so defense capacity of hosts is another influence factor, which is thought to combine to determine the result of the fighting. With the development of gene research technology, many human genetic loci were identified to be involved in GI diseases susceptibility, providing more insights into and knowledge about GI diseases. The current review aims to provide an update on the most recent progress in the identification and characterization of bacteria in GI diseases in a variety of organ systems and clinical conditions, and examine the invasion and escape mechanisms of pathogens that have been demonstrated in previous studies, we also review the existing data on the predictive factors of the host, mainly on genetic findings. These strategies may improve our understanding of the mechanisms underlying GI diseases, and open new avenues for the study of the associated conditions in the future.

Abstract
BACKGROUND Orofacial granulomatosis [OFG] is a rare syndrome that may be associated with Crohn's disease [CD]. We aimed to characterise this relationship and the management options in the biologic era. METHODS This multicentre case series was supported by the European Crohn's and Colitis Organisation [ECCO], and performed as part of the Collaborative Network of Exceptionally Rare case reports [CONFER] project. Clinical data were recorded in a standardised collection form. RESULTS This report includes 28 patients with OFG associated with CD: 14 males (mean age of 32 years, ±12.4 standard deviation [SD]) and 14 females [40.3 years, ±21.0 SD]. Non-oral upper gastrointestinal tract involvement was seen in six cases and perianal disease in 11. The diagnosis of OFG was made before CD diagnosis in two patients, concurrently in eight, and after CD diagnosis in 18. The distribution of OFG involved the lips in 16 cases and buccal mucosa in 18. Pain was present in 25 cases, with impaired swallowing or speaking in six. Remission was achieved in 23 patients, notably with the use of anti-tumour necrosis factors [TNFs] in nine patients, vedolizumab in one, ustekinumab in one, and thalidomide in two. A further five cases were resistant to therapies including anti-TNFs. CONCLUSIONS OFG associated with CD may occur before, concurrently with, or after the diagnosis of CD. Perianal and upper gastrointestinal [UGI] disease are common associations and there is a significant symptom burden in many. Remission can be obtained with a variety of immunosuppressive treatments, including several biologics approved for CD.

Abstract
BACKGROUND Melkersson-Rosenthal syndrome (MRS) is a rare disease characterized by the triad of recurrent orofacial edema, relapsing facial paralysis and plicated tongue. Histopathological features of MRS have not been extensively analyzed. METHODS This study investigated the histopathological aspects of oral lesions from 47 MRS patients. RESULTS The most common biopsy site was the upper lip, followed by the lower lip, gingiva and palate. The most important findings were ill-defined and well-formed granulomas. Lymphoplasmacytic inflammatory infiltrate was seen in early and late stages of MRS. Edema, fibrosis, vasodilatation and congestion were the most common finding in the lamina propria. Gingival and palate exams also demonstrated granulomatous infiltrates. Regarding the evolution time of the disease, we demonstrated that, in initial phases, there is a lymphoplasmacytic inflammatory infiltrates, followed by a granulomatous infiltrate and, subsequently, fibrosis. CONCLUSION Histopathological examination of oral lesions is helpful for the diagnosis of MRS; the absence of granulomatous inflammation does not exclude the diagnosis of syndrome. Clinical and histopathological analysis of the rare gingival and palate lesions is important, since all histopathological findings of the disease were detected in these sites.

Abstract
Melkersson-Rosenthal syndrome (MRS) is a neuromucocutaneous disease that manifests by the triad of recurrent orofacial edema (frequently as cheilitis granulomatosa), relapsing facial paralysis and plicated tongue. The cause of MRS remains unknown, but genetic predisposal and a relationship with inflammatory bowel disease are suspected. The objective of this research was to compare the frequency of class I and II HLA alleles in patients with a confirmed diagnosis of MRS with those of a healthy control group. We conduct a case-control study and typed of HLA A, B, C, DR, and DQ using molecular techniques. The study included 36 patients with MRS and 297 patients in the control group. There was an increase in the expression of HLA A*02 (p = 0.0269; OR: 1,79 [1,045-2,973]), HLA DRB1*11 (p < 0,0001; OR: 4,009 [2,214-7,277]), HLA DRB1*13 (not statistically significant) and HLA DQB1*03 (p = 0,0177; OR: 1,829 [1,122-2,978]) and low levels of HLA A*01 (p = 0.0046; OR: 0,097 [0,009-0,538]), HLA DRB1*04 (p = 0.0274; OR: 0,228 [0,053-0,844]), HLA DRB1*07 (p = 0,0091; OR: 0,183 [0,043-0,670]) and HLA DQB1*02 (p = 0.0051; OR: 0,312 [0,143-0,721]) in MRS patients compared with the control group. Crohn disease (CD) patients had disparate genetic profiles versus those with MRS. This single-institution study had a small cohort, because this disease is rare. Conclusions: There is a genetic predisposition toward MRS, involving associated and protective genes.

Abstract
BACKGROUND Orofacial granulomatosis (OFG) is a rare, inflammatory disorder of the mouth, in which some patients also have intestinal Crohn's disease (CD). The etiology remains largely unknown, although there is a high prevalence of atopy, and oral granulomas are also seen in other immune disorders particularly CD and sarcoidosis. We investigated whether genetic variants associated with an increased risk of CD, sarcoidosis, or atopy were also associated with susceptibility to OFG. METHODS Patients were stratified clinically as isolated oral manifestations (OFG only) or concurrent intestinal CD (OFG+CD). We genotyped 201 patients and 1023 healthy controls for risk variants in NOD2, IRGM, IL23R, ATG16L1 (CD), BTNL2 (sarcoidosis), and FLG (atopy). The coding regions of the NOD2 gene were screened for rare, potentially pathogenic variants in OFG. RESULTS A combined analysis of 3 CD-risk variants in NOD2 showed no association with any OFG subgroup. NOD2 p.L1007insC was associated with OFG+CD (P = 0.023) and IL23R p.R381Q with all OFG (P = 0.031). The sarcoidosis risk variant rs2076530 in BTNL2 was associated with all OFG (P = 0.013). We identified 7 rare missense NOD2 alleles in 8 individuals with OFG, 4 OFG-only patients and 4 patients with OFG+CD. There was a significant enrichment of NOD2 variants in the OFG+CD group compared to the OFG-only group (P = 0.008, common variants; P = 0.04, all common and rare variants). CONCLUSIONS Our findings suggest that genetic variants in NOD2 are only associated with OFG in patients with concurrent intestinal disease. A genome-wide association scan is needed to fully define the genetic architecture of OFG.

Abstract
Orofacial granulomatosis (OFG) is an uncommon chronic inflammatory disorder of the orofacial region. It is characterized by subepithelial noncaseating granulomas and has a spectrum of possible clinical manifestations ranging from subtle oral mucosal swelling to permanent disfiguring fibrous swelling of the lips and face. Etiopathogenesis is unknown. A range of systemic granulomatous disorders, including Crohn disease and sarcoidosis, may cause orofacial manifestations that cannot be distinguished from those of OFG. Treatment of OFG has proven difficult and unsatisfactory, with no single therapeutic model showing consistent efficacy in reducing orofacial swelling and mucosal inflammation.

Abstract
Orofacial granulomatosis (OFG) is an uncommon disease characterized by persistent or recurrent soft tissue enlargement, oral ulceration and a variety of other orofacial features. It could be an oral manifestation of a systemic disease. For a correct differential diagnosis, local and systemic conditions characterized by granulomatous inflammation should be excluded using appropriate clinical and laboratory investigations. In fact, the diagnosis of OFG may be confirmed only by histopathological identification of noncaseating granulomas. The literature from 1943 to 2014 was reviewed with emphasis on the etiology of OFG and on clinical manifestations of systemic pathologies associated with OFG. The precise cause of OFG is still unknown, although several theories have been suggested, such as infection, hereditary factors and allergy. OFG is a disease that has a wide spectrum of presentation, which may include the oral manifestation of a systemic condition such as Crohn's disease, sarcoidosis, granulomatosis with polyangiitis and Melkersson-Rosenthal syndrome.

Abstract
Orofacial granulomatosis (OFG) is the presence of persistent enlargement of the soft tissues of the oral and maxillofacial region, characterized by non-caseating granulomatous inflammation in the absence of diagnosable systemic Crohn's disease (CD) or sarcoidosis. Over 20 years have passed since OFG was first described and an extensive review of the literature reveals that there is no consensus whether OFG is a distinct clinical disorder or an initial presentation of CD or sarcoidosis. Furthermore, the precise cause of OFG is still unknown although several theories have been suggested including infection, genetic predisposition and allergy. The clinical outcome of OFG patients continues to be unpredictable. Current therapies remain unsatisfactory. Regular clinical review is indicated to identify the development of gastrointestinal or systemic involvement. The aim of this review was to analyse the developments in our understanding of the aetiology, pathogenesis and treatment protocols, with particular emphasis on management and outcomes of OFG since this entity was first described in 1985.

Abstract
Orofacial granulomatosis (OFG) is considered as an uncommon disease and nomenclature of the disease was subjected to debate for a long time. Although various aetiological agents such as food substances, food additives, dental materials and various microbiological agents have been implicated in the disease process its precise pathogenesis is yet to be elucidated. Delayed type of hypersensitivity reaction appears to play a significant role, although the exact antigen inducing the immunological reaction varies in individual patients. However, evidence for the role of genetic predisposition to the disease is sparse. The underlying immunological mechanism appears to show some similarities between OFG and Crohn's disease, emphasizing the need for more comparative studies of the two entities. Therefore, we propose the term idiopathic OFG as a better term for those cases restricted to oral region without any identifiable known granulomatous disease and the diagnosis should not be changed until the patient develops systemic manifestations of a specific granulomatous condition. This review attempts to discuss the role of different aetiological agents and certain aspects of pathogenesis of OFG.

Abstract
BACKGROUND Orofacial granulomatosis (OFG) is a chronic inflammatory disorder presenting characteristically with lip swelling but also affecting gingivae, buccal mucosa, floor of mouth, and a number of other sites in the oral cavity. Although the cause remains unknown, there is evidence for involvement of a dietary allergen. Patch testing has related responses to cinnamon and benzoate to the symptoms of OFG, with improvement obtained through exclusion diets. However, an objective assessment of the effect of a cinnamon- and benzoate-free diet (CB-free diet) as primary treatment for OFG has not previously been performed. Thus, this study was undertaken to investigate the benefits of a CB-free diet as first-line treatment of patients with OFG. MATERIALS AND METHODS Thirty-two patients with a confirmed diagnosis of OFG were identified from a combined oral medicine/gastroenterology clinic. All had received a CB-free diet as primary treatment for a period of 8 weeks. Each patient underwent a standardized assessment of the oral cavity to characterize the number of sites affected and the type of inflammation involved before and after diet. RESULTS There was a significant improvement in oral inflammation in patients on the diet after 8 weeks. Both global oral and lip inflammatory scores improved (P<0.001), and there was significant improvement in both lip and oral site and activity involvement. However, improvement in lip activity was less marked than oral activity. Response to a CB-free diet did not appear to be site specific. A history of OFG-associated gut involvement did not predict a response to the diet. CONCLUSIONS The impact of dietary manipulation in patients with OFG can be significant, particularly with regard to oral inflammation. With the disease most prevalent in the younger population, a CB-free diet can be recommended as primary treatment. Subsequent topical or systemic immunomodulatory therapy may then be avoided or used as second line.

Abstract
Orofacial granulomatosis is an uncommon clinicopathological entity describing patients who have oral lesions characterized by persistent and/or recurrent labial enlargement, oral ulcers and a variety of other orofacial features, who on lesional biopsy have lymphoedema and non-caseating granulomas. The aetiology of oral lesions with non-caseating granulomas includes oral Crohn's disease (some patients with oral lesions will develop typical bowel symptoms of Crohn's disease in ensuing months to years), tooth-associated infections, sarcoidosis and food or contact allergies. Treatment of orofacial granulomatosis is not reliably effective and may not be always necessary, although most patients do require some medical intervention.
