Analysis of the detection of non-caseating granuloma under endoscopy in 199 patients with Crohn′s disease / 中华消化杂志

Objective:To explore the detection rate of non-caseating granuloma under endoscopy in patients with Crohn′s disease and its influencing factors, in order to improve the pathological diagnosis rate of Crohn′s disease.Methods:From July 2016 to April 2021, at the First Affiliated Hospital of Soochow University, 199 patients who met the clinical diagnostic criteria for Crohn′s disease and underwent endoscopic biopsy were collected. The detection rates of non-caseating granulomas in all patients with Crohn′s disease, in different types (primary and recurrent) and whether the biopsy site included the colon were analyzed. According to whether non-caseating granulomas were detected by endoscopic biopsy, the patients were divided into the detected group and the undetected group. The clinical data of the two groups of patients were compared, which included gender, age, course of disease, body mass index, smoking status, clinical manifestations (abdominal pain, diarrhea, gastrointestinal bleeding, perianal lesions, weight loss, fever, intestinal obstruction), therapeutic medication (5-aminosalicylic acid, immunosuppressants, glucocorticoid, biological agents, exclusive enteral nutrition), history of bowel surgery, laboratory examination results (hemoglobin, platelet count, neutrophil count, C-reactive protein, erythrocyte sedimentation rate, albumin), endoscopic manifestation (ulcer, fistula, stricture), simplified Crohn′s disease activity index (CDAI), total number of biopsy samples, and site of biopsy. Chi-square test, continuity correction chi-square test, Mann-Whitney U test and Fisher exact test were used for statistical analysis, and logistic regression analysis was used to analyzed the influencing factors of detection of non-caseating granulomas under endoscopy. Results:Among the 199 patients with Crohn′s disease, 67 cases were detected with non-caseating granuloma (detected group), and the overall detection rate was 33.7% (67/199); 132 cases were not detected with non-caseating granuloma (undetected group). The detection rate of non-caseating granulomas in patients with primary Crohn′s disease was higher than that of recurrent patients (39.9%, 59/148 vs. 15.7%, 8/51), and the detection rate of non-caseating granulomas in patients with Crohn′s disease whose biopsy site included the colon was higher than that of patients whose biopsy site did not include colon (64.1%, 25/39 vs. 26.3%, 42/160), and the differences were statistically significant ( χ2=9.93 and 20.12 , P=0.002 and <0.001). The age of patients in the detected group was younger than that of the undetected group; the course of disease of the detected group was shorter than that of the undetected group; the proportions of patients with abdominal pain and history of biological treatment in the detected group were lower than those of the undetected group; the simplified CDAI score of the detected group was higher than that of the undetected group; and the total number of biopsy samples of the detected group was more than that of the undetected group (30.0 years old (25.0 years old, 37.00 years old) vs. 32.0 years old (28.0 years old, 41.0 years old); 1.0 year (0.0 year, 3.0 years) vs. 2.0 years (0.0 year, 5.0 years), 61.2%, 41/67 vs. 75.8%, 100/132; 0, 0/67 vs. 10.6%, 14/132; 5.00 (2.00, 7.00) vs. 4.00 (2.00, 6.00); 10 (8, 12) vs. 6 (3, 9)), and the differences were statistically significant ( Z=-2.29, -1.99, χ2=4.56, corrected χ2=6.11, Z=-2.05, -5.64, all P<0.05). The case number of biopsy location in terminal ileum, colon, ileocolon, upper gastrointestinal tract, terminal ileum+ upper gastrointestinal tract, ileocolon+ upper gastrointestinal tract in the detected group was 36, 4, 18, 1, 5 and 3, respectively, compared with those of undetected group (94, 4, 8, 11, 13 and 2), the difference was statistically significant (Fisher′s exact test, P<0.001). The results of multivariate logistic regression analysis suggested that the total number of biopsy samples, whether the biopsy site included the colon and disease type were independent influencing factors for the detection of non-caseating granulomas under endoscopy in patients with Crohn′s disease (regression coefficients=0.157, 0.979 and -0.960, OR=1.171, 2.662 and 0.383; 95% confidence interval 1.067 to 1.284, 1.140 to 6.214, 0.158 to 0.929; P=0.001, 0.024 and 0.034). Conclusions:For endoscopic examination in patients with suspected Crohn′s disease, the total number of biopsy samles should be increased as much as possible, and biopsy should be performed at the colonic lesions, in order to improve the detection rate of non-caseating granulomas under endoscopy thereby providing more pathological evidence for the diagnosis of Crohn′s disease.

Incidence of Side-effects After Weekly Iron and Folic Acid Consumption Among School-going Indian Adolescents

Objective: To estimate incidence of side effects after weekly iron and folic acidsupplementation (WIFS) in Delhi and Haryana. Methods: In this cross-sectional school-based study, data were collected from 4,183 adolescents on WIFS consumption and sideeffects experienced first time of receipt of WIFS (week 1), and in last two consecutive weeks(week 2,3). Week 3 was 48 hours preceding the survey. Results: WIFS consumption in week1, 2 and 3 was 85%, 63% and 52%, respectively. Side effects reported were highest in firstweek (25%) and reduced to 7% (week 2) and 5% (week 3). Side effects most reported wereabdominal pain (80%) and nausea (10%). Adolescents (45%) who faced a side-effect in week1 did not consume WIFS in subsequent week. Conclusion: Incidence of side effects was low,but it affected compliance. Positive reinforcement to students who face side effects requiresstrengthening by teachers.

Non-Caseating Granulomatous Infective Spondylitis: Melioidotic Spondylitis

STUDY DESIGN: Retrospective clinical analysis. PURPOSE: To delineate the clinical presentation of melioidosis in the spine and to create awareness among healthcare professionals, particularly spine surgeons, regarding the diagnosis and treatment of melioidotic spondylitis. OVERVIEW OF LITERATURE: Melioidosis is an emerging disease, particularly in developing countries, associated with a high mortality rate. Its causative pathogen, Burkholderia pseudomallei, has been labeled as a bio-terrorism agent. METHODS: We performed a retrospective analysis of patients who were culture positive for B. pseudomallei. Assessment of patients was performed using clinical, radiological, and blood parameters. Clinical measures included pain, neurological deficit, and return to work. Radiological measures included plain radiography of the spine and magnetic resonance imaging. Blood tests included erythrocyte sedimentation rate and C-reactive protein levels. RESULTS: Four patients having melioidosis with spondylitis were evaluated. All of them had diabetes mellitus; three had multiple abscesses which required incision and drainage. Their clinical spectrum was similar to that of tuberculous spondylitis; all had back pain and radiology revealed infective spondylodiscitis with prevertebral and paravertebral collections with psoas abscess. Three patients underwent ultrasound-guided drainage of the psoas abscess and one had aspiration of the subcutaneous abscess. Bacteriological cultures showed presence of B. pseudomallei, and histopathology showed non-caseating granulomatous inflammation. All patients were treated with intravenous Ceftazidime for 2 weeks, followed by oral bactrim double strength and Doxycycline for 20 weeks. All patients improved with treatment and were healed at follow up. CONCLUSIONS: Melioidosis presents with a clinical spectrum similar to that of tuberculosis. A diagnosis of melioidotic spondylitis should be considered, particularly in patients with diabetes with neutrophilic leukocytosis and clinical-radiological features suggestive of infective spondylodiscitis. Bacteriological culture and histopathology helps in differentiating the two conditions. Health education for healthcare professionals is important for correctly diagnosing this disease.

A case of endometrial tuberculosis complicated by Pott’s spine with paraplegia.

Extra-pulmonary tuberculosis has shown an increasing trend in developing countries and accounts for 15-20% of total tuberculosis cases in India. Extra-pulmonary cases are usually diagnosed late due to vague and subtle signs & symptoms at a stage when major irreversible tissue damage had occurred. Tuberculosis is a chronic disease with infection remaining dormant for years in body to get activated whenever the immunity decreases. Spinal and cranial TB has the gravest manifestations, while the abdominal, female genital or pelvic TB poses a challenge because of lack of specific diagnostic tests. Here we are reporting a case of endometrial tuberculosis which was diagnosed very late, followed by treatment default and finally got complicated with Pott’s spine with paraplegia due to haematogenous spread. Timely intervention and anti-tubercular treatment improved the symptoms. It stresses on keeping the high suspicion of tuberculosis in unresponsive and persistent general symptoms.

A Case of Isolated Orbital Sarcoidosis

PURPOSE: The authors report a case of orbital sarcoidosis without evidence of systemic involvement. CASE SUMMARY: A 33-year-old female had a 1 month history of erythematous eyelid swelling. On physical examination, a firm and non-tender mass was observed diffusely along the upper, lower and medial canthal areas. A computed tomography (CT) scan showed a diffuse mass in the anterior orbit. We performed an incisional biopsy and histopathological examination revealed non-caseating granulomas and no evidence of a foreign body. Acid-fast-bacilli (AFB), methenamine silver and periodic-acid-schiff (PAS) stain showed no evidence of infection and chest radiograph was normal. Polymerase chain reaction (PCR) and interferon gamma secretion test showed no evidence of tuberculosis. Antinuclear antibody (ANA) and antineutrophil cytoplasmic antibody (ANCA) were negative and angiotensin converting enzyme (ACE) was within the normal range. Further systemic evaluations were compatible with a diagnosis of orbital sarcoidosis and oral prednisone was prescribed. Six weeks later, the erythematous eyelid swelling had disappeared and there was no evidence of recurrence to date.

A Case of Scar Sarcoidosis of The Eyelid

PURPOSE: We report the case of a patient with scar sarcoidosis that developed along a previous eyelid scar. There was no evidence of ocular or systemic sarcoidosis. METHODS: A 29-year-old man presented with a mass on his right eyelid that had been present for two month. On ocular examination an erythematous, firm, and non-tender mass was diffusely palpable along the upper and lower eyelid scar. We performed an incisional biopsy of the lower lid mass. RESULTS: Histopathologic examination of the mass revealed numerous, noncaseating granulomas with multi-nucleated giant cells. The giant cells contained asteroid bodies and calcium oxalate crystals characteristic of sarcoidosis, although the patient had no other evidence of systemic sarcoidosis. The mass in the upper lid disappeared after intralesional triamcinolone injections. CONCLUSIONS: This case represents a rare occurrence of sarcoidosis that arose in an old eyelid scar. Scar sarcoidosis should be considered in the differential diagnosis of an unusual mass in a scar.
