RESUMO
BACKGROUND: There is an emerging role of fungal dysbiosis in the pathogenesis of inflammatory bowel disease. Prevalence of Candida in patients with active ulcerative colitis (UC) and the effect of fluconazole therapy in reducing disease activity of UC are not known. PATIENTS AND METHODS: All consecutive consenting patients with active UC defined as Mayo score ≥3 were evaluated for presence of Candida by stool culture and predictors for presence of Candida were identified. Those who had evidence of Candida in the stool were randomized to receive oral fluconazole 200 mg daily or placebo for 3 weeks along with standard medical therapy. Patients were assessed by clinical, sigmoidoscopy, and laboratory parameters at baseline and at 4 weeks. The primary outcome was clinical and endoscopic response at 4 weeks defined by a 3-point reduction in Mayo score. Secondary outcomes were reduction in fecal calprotectin, histologic response, and adverse events. RESULTS: Of the 242 patients with active UC, 68 (28%) patients had Candida in stool culture. Independent predictors for presence of Candida in patients with active UC were partial Mayo score of ≥3 and steroid exposure. Among those with Candida on stool culture (n=68), 61 patients fulfilled eligibility criteria and were randomized to receive fluconazole (n=31) or placebo (n=30). Three-point reduction in Mayo score though was numerically higher in the fluconazole group than the placebo group but was not statistically significant [5 (16.1%) vs. 1 (3.33%); P =0.19]. Postintervention median Mayo score was lower in fluconazole than placebo group [4 (3, 5) vs. 5 (4, 6); P =0.034]. Patients in fluconazole group had more often reduction in fecal calprotectin [26 (83.9%) vs. 11 (36.7%); P =0.001] and histologic scores [23 (74.1%) vs. 10 (33.3%); P =0.001] compared with placebo. All patients were compliant and did not report any serious adverse event. CONCLUSION: Candida colonization is found in 28% of patients with UC. Steroid exposure and active disease were independent predictors for the presence of Candida . There was no statistically significant difference in the number of patients who achieved 3-point reduction in Mayo score between 2 groups. However, clinical, histologic, and calprotectin levels showed significant improvement in fluconazole group.

BACKGROUND: Polymorphisms in thiopurine methyltransferase (TPMT) and Nudix hydrolase-15 (NUDT15) have been implicated as the predominant cause of thiopurine induced leukopenia in the Western countries and East Asia respectively. Exact role of these polymorphisms in South Asian population with inflammatory bowel disease (IBD) is uncertain. METHODS: We included consecutive patients with IBD who were initiated on thiopurines at a center in North India. The dosage of thiopurines was titrated using regular monitoring of hemogram and liver function tests. Three TPMT polymorphisms (c.238 G > C, c.460 G > A, and c.719A > G) and one NUDT15 polymorphism (c.415 C > T) were assessed. Comparison regarding incidence of leukopenia and maximum tolerated thiopurine dosage was performed between those with wild polymorphism and those with TPMT and NUDT15 polymorphisms, respectively. RESULTS: Of the 119 patients (61 males, mean age 36.8 ± 13.5 years), 105 (88.2%) had ulcerative colitis and 14 (11.8%) had Crohn's disease. Leukopenia was noted in 33 (27.7%), gastrointestinal intolerance in 5 (4.2%) and pancreatitis in 2 (1.6%). TPMT polymorphisms were detected amongst five patients of whom 1 developed leukopenia. NUDT15 polymorphism was noted in 13 patients of whom 7 had leukopenia. The odds of developing leukopenia in TPMT polymorphism were non-significant (0.77, 95% CI:0.0822 to 7.2134, P = 0.819) but were significantly higher in those with NUDT15 polymorphism (3.5933, 1.1041 to 11.6951, P value: = 0.0336). CONCLUSION: NUDT15 polymorphism was more frequent than TPMT polymorphisms and was associated with thiopurine induced leukopenia. However, the tested polymorphisms account for only 24.2% of the risk of thiopurine induced leukopenia.

BACKGROUND: Ileocecal thickening (ICT) on imaging could result from diverse etiologies but may also be clinically insignificant. AIM: Evaluation of role of combined 2-deoxy-2-fluorine-18-fluoro-D-glucose(18F-FDG)-positron emission tomography and computed tomographic enterography (PET-CTE) for determination of clinical significance of suspected ICT. METHODS: This prospective study enrolled consecutive patients with suspected ICT on ultrasound. Patients were evaluated with PET-CTE and colonoscopy. The patients were divided into: Group A (clinically significant diagnosis) or Group B (clinically insignificant diagnosis) and compared for various clinical and radiological findings. The two groups were compared for maximum standardized uptake values of terminal ileum, ileo-cecal valve, cecum and overall. RESULTS: Of 34 patients included (23 males, mean age: 40.44 ± 15.40 years), 12 (35.3%) had intestinal tuberculosis, 11 (32.4%) Crohn's disease, 3 (8.8%) other infections, 1 (2.9%) malignancy, 4 (11.8%) non-specific terminal ileitis while 3 (8.8%) had normal colonoscopy and histology. The maximum standardized uptake value of the ileocecal area overall (SUVmax-ICT-overall) was significantly higher in Group A (7.16 ± 4.38) when compared to Group B (3.62 ± 9.50, P = 0.003). A cut-off of 4.50 for SUVmax-ICT-overall had a sensitivity of 70.37% and a specificity of 100% for prediction of clinically significant diagnosis. Using decision tree model, the SUVmax-ICT with a cut-off of 4.75 was considered appropriate for initial decision followed by the presence of mural thickening in the next node. CONCLUSION: PET-CTE can help in discrimination of clinically significant and insignificant diagnosis. It may help guide the need for colonoscopy in patients suspected to have ICT on CT.

BACKGROUND: Procalcitonin may be increased in active ulcerative colitis (UC). We investigated the role of procalcitonin in predicting response in acute severe UC (ASUC). METHODS: Consecutive patients with ASUC diagnosed on basis of Truelove and Witts criteria were enrolled. Serum procalcitonin levels for consecutive patients were measured at admission and day 3. We assessed role of procalcitonin values at presentation and at day 3 in assessing response on day 3 (Oxford's criteria) and need for second line therapy (day 28). RESULTS: Of fifty patients (23 males, mean age: 35.98±13.8 years), 16 did not respond (day 3). Ten (20%) patients required second-line therapy. Baseline procalcitonin was significantly associated with response on day 3 (P=0.016). There was no association between day 1 or day 3 procalcitonin and need for second-line rescue therapy. CONCLUSION: Serial procalcitonin is not an effective biomarker for predicting outcomes or need for second line therapy in ASUC.

BACKGROUND: Response to antitubercular therapy (ATT) is often used to differentiate intestinal tuberculosis (ITB) from Crohn's disease. Role of non-invasive biomarkers to predict mucosal response to ATT is unclear. MATERIALS AND METHODS: A prospective study to compare faecal calprotectin and serum C-reactive protein (CRP) levels at diagnosis, 2 and 6 months of ATT in patients with suspected ITB started on ATT was done. The patients were eventually divided into two groups: ITB or alternative diagnosis (OTH). Decline of calprotectin and CRP levels was used to compute area under the receiver operating characteristic (AUROC) to predict mucosal healing at 2 months. RESULTS: Thirty-seven patients (mean age: 34.95 ± 16.35 years, 23 males) were included and 28 (75.67%) were diagnosed as ITB while nine (24.32%) had alternative diagnosis (OTH). The median faecal calprotectin values of ITB and OTH groups at baseline, 2 months and 6 months were 216 and 282 µg/g (P = 0.466), 43 and 216 µg/g (P = 0.003), and 26 and 213 µg/g (P < 0.001), respectively. The median CRP values at baseline, 2 months and 6 months were 18 and 30 mg/L (P = 0.767), 4.7 and 15 mg/L (P = 0.025), and 3 and 10.85 mg/L (P = 0.068), respectively. The AUROC of percent decline in faecal calprotectin and serum CRP at 2 months for mucosal healing were 0.8287 [95% confidence inteval (CI) 0.6472-1] and 0.6018 (95% CI 0.4079-0.7957), respectively. CONCLUSION: Faecal calprotectin can help in assessing response to therapy in suspected ITB patients started on empirical ATT.

OBJECTIVES: Evaluation of a combination of antibiotics as an adjuvant therapy in acute severe ulcerative colitis (ASUC). METHODS: Patients with ASUC were randomized to either infusions of placebo or intravenous ceftriaxone and metronidazole in addition to standard care. Primary outcome was response on day three according to Oxford's criteria. Secondary outcome measures included changes in partial Mayo score, CRP levels, fecal calprotectin (day three), and need for second-line therapy, hospital stay, and mortality (day 28). RESULTS: Fifty patients (25 in each group, median age: 33 years, 23 males) were included. The number of patients with fulminant disease in the antibiotic group were 16 (64%) as compared to 7 (28%) in the standard of care group. Complete response on day three was attained by 7 (28%) in the antibiotic and 6 (24%) standard of care group (p = 1.00). Three patients from the antibiotic group underwent colectomy and three received intravenous cyclosporine whereas four patients in the standard of care group received cyclosporine (p = 0.725). There was no significant difference in change in CRP, Partial Mayo score, and fecal calprotectin between the two groups on day three. CONCLUSION: Combination of intravenous ceftriaxone and metronidazole did not improve outcomes in ASUC.Acronym: AAASUC trialRegistration Number: CTRI/2019/03/018196 and NCT03794765.

Hereditary transthyretin (TTR) amyloidosis is a multisystem disorder caused by extracellular amyloid deposition, usually presenting with neurological and cardiovascular involvement. Gastrointestinal involvement, if present, is usually in the form of motility symptoms like diarrhea, constipation, or diarrhea alternating with constipation. Presentations mimicking ulcerative colitis without other system involvement are rare. Here we present a case of a young female from northern India, who presented with blood-admixed diarrhea without any feature of any other system involvement. She was diagnosed and treated as ulcerative colitis for two years with ambivalent response, although the compliance to therapy was also poor. She was re-evaluated when she presented with recurrence of symptoms and new onset dysphagia. On evaluation, she was diagnosed as hereditary transthyrtetin related amyloidosis.
RESUMO
BACKGROUND AND AIM: Disease activity and severity of ulcerative colitis (UC) is assessed using colonoscopy, which is invasive, costly and has poor patient acceptability. The role of non-invasive biomarkers of intestinal inflammation in the evaluation of patients with UC is not known. The aim of the study was to examine the role of serum C-reactive protein (SCRP), fecal myeloperoxidase (FMPO) and fecal lactoferrin (FLF) in assessing disease severity, activity and response to therapy. METHODS: Consecutive patients with idiopathic UC (IUC) attending our hospital from July 2005 to September 2006 were studied. All underwent clinical, endoscopic and histological assessment for disease activity, extent, severity and estimation of SCRP, FMPO and FLF levels at baseline and follow up (FU). An equal number of healthy age-matched controls were studied for biomarker levels. RESULTS: A total of 37 patients (mean age 37 +/- 12 years) were studied. All three biomarkers were elevated more often in the cases than in the controls (all P = 0.000). Cases with severe IUC had higher CRP, MPO and FLF titers than those without severe IUC. At FU, a significant fall in biomarker levels paralleled the reduction in Mayo's scores. All three biomarkers showed a high degree of correlation with each other. The areas under the curve for FLF, MPO and CRP were 1.00, 0.867 and 0.622, respectively. The sensitivity and specificity of markers were: FLF (94%, 100%), FMPO (89%, 51%) and SCRP (24%, 100%). CONCLUSION: Biomarkers are useful in assessing disease activity, severity and response to therapy in patients with UC. They showed a high degree of correlation with each other.

AIM OF THE STUDY: Incidence and predictors of antitubercular therapy (ATT)-related hepatitis in abdominal tuberculosis are not known. The aim of the study was to identify the incidence and predictors of ATT-induced hepatitis in abdominal tuberculosis. MATERIAL AND METHODS: A retrospective analysis of patients who received ATT for suspected abdominal tuberculosis with complete follow-up was done. We excluded patients with underlying chronic or acute liver disease necessitating an alteration in the usual ATT at start. We recorded the occurrence of ATT-induced hepatitis and compared patients with and without ATT hepatitis for any predictors of ATT-induced hepatitis. RESULTS: Of 163 patients, 22 were excluded (17 missing information, 5 chronic liver disease). One hundred and forty-one patients (mean age: 34.33 ±15.18 years, males: 72) were included. The Mantoux test was positive in 78; 1 had HIV and 32 had an abnormal chest X-ray. Six patients had an alternative diagnosis and 11 needed surgery. Forty-nine (34.8%) had extra-abdominal involvement. Ten patients (7.1%) developed ATT-induced hepatitis. Patients with extra-abdominal tubercular involvement had a greater risk of developing ATT-induced hepatitis (p-value 0.003). None of the other parameters including hematological tests, liver function tests and biochemical parameters were different between the two groups. CONCLUSIONS: Seven percent of patients treated for abdominal tuberculosis developed ATT hepatitis. Presence of extra-abdominal involvement was associated with ATT hepatitis.
RESUMO
BACKGROUND AND AIM: Systemic sclerosis (SSc) is known to involve the gastrointestinal (GI) tract, resulting in dysmotility, gastroesophageal reflux disease, and mucosal changes causing significant morbidity. The study aimed to assess esophageal motility and duodenal mucosal changes in SSc. METHODS: This is a prospective, cross-sectional, single-center study of 23 patients with SSc diagnosed on the basis of standard criteria. Clinical details including the GI symptoms were recorded. All of them underwent esophagogastroduodenoscopy with duodenal biopsy, and 21 underwent esophageal manometry. RESULTS: Regurgitation, heartburn, and dysphagia were seen in 19 (82%), 16 (69%), and 10 (43%) patients, respectively. On endoscopy, 19 patients (83%) showed changes of reflux esophagitis (4 had grade C esophagitis), and 3 had esophageal candidiasis. Of the 21 patients who underwent esophageal manometry, 13 (62%) had absent peristalsis, 6 (28%) had ineffective peristalsis, and 10 (48%) had hypotensive lower esophageal sphincter (LES). Duodenal biopsy showed partial villous atrophy in 9 (39%) patients, increased intraepithelial lymphocytes in 18 (78%), and excess of mononuclear inflammatory cells in lamina propria in 21 (91%). Partial villous atrophy was seen more commonly in those with abnormal esophageal peristalsis and a hypotensive LES. CONCLUSION: Most of the patients with SSc had esophageal dysmotility in the form of absent peristalsis, ineffective esophageal peristalsis, and hypotensive LES. Histology of descending duodenum demonstrated partial villous atrophy and chronic inflammatory infiltrates in most of the patients with SSc.
RESUMO
Background: The relationship between diabetes mellitus and tuberculosis (TB) has received increasing attention, and diabetes may be associated with poor outcomes in pulmonary TB. Clinical relevance of HbA1c measurement in abdominal TB is unknown. Methods: We did a retrospective study of consecutive patients diagnosed with abdominal TB and treated with antitubercular therapy for 6 months. Patients were categorized as those with normal HbA1c (<5.7%) or those having elevated HbA1c (≥5.7%). The patients' baseline characteristics, their mode of presentation, type of abdominal TB, and their outcomes after treatment were retrieved and compared. Results: Of 84 patients included in the final analysis, the mean age was 35.52 years and 50% were male. While 19 patients had a confirmed diagnosis, 65 patients were diagnosed as probable abdominal TB. Of the 84 patients, 60 patients (71.43%) had a normal HbA1c and 24 patients (28.57%) had an elevated HbA1c. Those with elevated HbA1c were older in age (47.00 ± 13.98 vs. 30.93 ± 13.91; P < 0.001), and there were more males (75.0% vs. 40.0%; P = 0.004) as compared to the normal HbA1c group. However, other parameters such as their presenting features, pattern of abdominal TB, extra-abdominal involvement, outcomes after treatment, and need of intervention (surgery and dilatation) were comparable between both the groups. Conclusion: Presence of prediabetes or diabetes does not seem to impact the clinical presentation or outcomes in patients with abdominal TB.

INTRODUCTION: Data on the use of Xpert Mtb/Rif for the diagnosis of intestinal tuberculosis is sparse. We report on the utility of Xpert Mtb/Rif testing for diagnosis of intestinal tuberculosis (ITB) in patients with ileocecal ulcers. METHODOLOGY: We performed a retrospective analysis of patients with ileocecal ulcers and suspected to have ITB and in whom testing of intestinal tissue for Xpert Mtb/Rif was performed. The patients were divided into two groups: those with a final diagnosis of intestinal tuberculosis and those with other diagnosis. These patients were compared for clinical features and presentation. The sensitivity, specificity, positive predictive value, and negative predictive value of Xpert Mtb/Rif for the diagnosis of ITB were calculated. RESULTS: Of the 40 patients studied, 23 were women and the mean age was 32.92â±â12.78 years. Abdominal pain was present in 33 (88.5%) patients and diarrhea in 12 (30%). A total of 25 patients had underlying ITB whereas 15 patients had other diagnoses (Crohn's disease, amebiasis, nonspecific ileitis, etc.). The sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of GeneXpert-Mtb/Rif was 32% (CI: 14.95-53.50%), 100% (78.2-100), 46.88% (40.27-53.59%), 100 & 57.50 (40.89-72.89%) respectively. CONCLUSION: A positive GeneXpert-Mtb/Rif helps in the diagnosis of ITB, but the sensitivity is low.
RESUMO
BACKGROUND AND AIM: Alcohol-related diseases constitute the third largest health problem after heart disease and cancer in the world. The objective was to study the effects of chronic alcohol intake on small bowel cellular functions with focus on brush border enzymes, membrane enzymes, cellular enzymes and their relationship with structural changes in small bowel mucosa of chronic alcoholics. METHODS: Duodenal biopsies were obtained by upper gastrointestinal endoscopy of chronic alcoholics having alcoholic liver disease (ALD) with and without cirrhosis. The biopsies were then processed for enzymatic assays to analyze the status of cellular functions. Light microscopy, transmission electron microscopy, and scanning electron microscopy were done to study the morphological alterations. Control group consisted of nonalcoholic gastroesophageal reflux disease patients reporting for routine endoscopy. RESULTS: The experimental group consisted of ALD patients which showed significant difference (P < 0.01) in cellular functions when compared with controls. The light microscopy showed partial villous atrophy, increase in lamina propria infiltrate, and intraepithelial lymphocytes as main findings in the alcoholic group. Ultrastructural evaluation revealed changes like widened intercellular junction, distorted microvilli, increased rough endoplasmic reticulum, and increased and dilated mitochondria. The enzyme parameters correlated positively with the mucosal morphology parameters indicating a direct relationship. CONCLUSION: The study brought out the changes in small bowel of chronic alcoholics having ALD at both cellular and subcellular levels which correlated significantly.

BACKGROUND AND AIM: In celiac disease (CD), abnormalities of brush border enzyme activities have been detected in the course of the disease activity. There are conflicting results on intestinal mucosal enzyme activities and its correlation to mucosal injury in CD. The aim of the present study was to evaluate the brush border enzyme activities (disaccharidases and alkaline phosphatase) in the duodenal mucosa of North Indian children with CD and to examine their correlation to duodenal mucosal morphological alterations. METHODS: This prospective study included 71 children with CD and 29 controls (patients with gastroesophageal reflux disease) in whom upper gastrointestinal endoscopy was performed and distal duodenal biopsies were taken for histological assessment, and estimation of disaccharidases and alkaline phosphatase activities. Each biopsy sample was classified according to the modified Oberhuber classification. Lactase, sucrase, maltase and alkaline phosphatase activities were estimated in duodenal biopsy homogenates from patients with CD and from controls. The association between enzyme activities and duodenal morphology was examined. RESULTS: The mean age of the 71 patients with CD (M:F, 43:28) was 6.0 +/- 0.3 years and mean age of onset of symptoms was 2.7 +/- 0.4 years. Sixty-four of 71 (90.1%) CD patients showed type 3 (destructive) lesion, whereas it was grade 0 in all patients with gastroesophageal reflux disease. In CD and patients with gastroesophageal reflux disease, the mean level (IU/g protein) of lactase was 12.1 +/- 0.9 versus 24.4 +/- 1.0 (P < 0.001), mean level of sucrase was 25.9 +/- 1.9 versus 42.5 +/- 1.9 (P < 0.001), mean level of maltase was 56.6 +/- 3.5 versus 76.1 +/- 13.0 (NS), and mean level of alkaline phosphatase was 602.8 +/- 56.2 versus 1359.3 +/- 51.2 (P < 0.001), respectively. The mean disaccharidases and alkaline phosphatase levels were not significantly different in patients with milder lesions (type 2 and type 3a) compared with those of control. However, mean lactase, sucrase and alkaline phosphatase levels were significantly lower (P < 0.001) in CD patients with moderate (type 3b) and severe (type 3c) lesions compared with control. CONCLUSIONS: A generalized decrease of disaccharidases and alkaline phosphatase activity was seen in the duodenal mucosa of children with CD. The depressed activities of lactase, sucrase and alkaline phosphatase were well correlated with the histological grade of duodenal mucosal lesions in children with CD.

OBJECTIVES: Lymphocytic gastritis (LG) is characterized by the presence of > or = 25 lymphocytes/100 epithelial cells in the gastric surface and pit epithelium. An association of LG with Helicobacter pylori infection or celiac disease (CD) has been suggested. The aim of this study was to verify the relation of LG with CD, with and without H pylori infection, in children. PATIENTS AND METHODS: A total of 164 children with CD diagnosed between June 2003 and October 2005, in whom gastric and duodenal biopsies were performed simultaneously, were enrolled prospectively. The control group was composed of 164 children without CD, matched for sex and age, who were undergoing upper digestive endoscopy. H pylori was searched for in gastric biopsy specimens sectioned and stained with hematoxylin and eosin, and a modified Giemsa stain for H pylori was performed for confirmation. The Student t test was used to compare quantitative measurements between groups. RESULTS: LG was found in 69 (42.1%) patients with CD. Positive cases had a mean of 43.9 +/- 1.5 intraepithelial lymphocytes per 100 surface epithelial cells, compared with a mean of 13.4 +/- 0.4 in negative cases and 7.8 +/- 0.5 in non-CD control children (P<0.0001). Patients not showing LG did, however, show significantly increased gastric intraepithelial lymphocytes compared with the control children. Nine of 164 CD patients, and 4 of 69 patients with LG, had positive results for H pylori. CONCLUSIONS: This study supports a pathogenetic relation between CD and LG. CD without LG also showed increased gastric intraepithelial lymphocytes. H pylori infection may be another cause of LG in children.

Tuberculosis is a common clinical problem which can involve virtually any organ and mimic a multitude of clinical conditions. Colonic tuberculosis is a type of intestinal tuberculosis which involves the colon and mimics inflammatory bowel disease. Occasionally, it is also confused with colonic malignancy. We report the case of a young female who presented with abdominal pain, bleeding per rectum. Abdominal X-ray showed evidence of thumb-printing. A possibility of ischemic colitis was entertained. However, further investigation unraveled the presence of tubercular colitis. The patient improved with anti-tubercular therapy. Colonic tuberculosis can mimic a number of clinical entities and should be considered in differential diagnosis of colonic lesions in endemic areas.

Recent studies have identified sprue-like illness associated with the use of the antihypertensive agent olmesartan medoxomil. However, whether this condition is specific to the use of olmesartan or is associated with the use of drugs belonging to the class of "sartans" remains to be clarified. A 45-year-old woman with chronic kidney disease along with hypothyroidism and hypertension presented with chronic diarrhea and significant weight loss. Endoscopy of the upper gastrointestinal tract showed scalloping and grooving of the duodenum, and histopathological examination showed subtotal villous atrophy. She was on telmisartan for hypertension, which was discontinued. Subsequently, diarrhea ameliorated dramatically, and she regained weight. To our knowledge, this is the first study to report telmisartan-associated sprue-like enteropathy. Further, we have reviewed the cases of patients with sprue-like enteropathy caused by valsartan, irbesartan, and eprosartan.
RESUMO
BACKGROUND: Vitamin D is recognised to have multiple actions, including role in immune modulation. The prevalence and impact of vitamin D deficiency (VDD) in abdominal tuberculosis is unknown. METHODS: We report the prevalence and clinical impact of VDD in patients with abdominal tuberculosis. The patients were divided into two groups: VDD (<20 ng/ml) or vitamin D sufficient (VDS) (⩾20 ng/ml). Groups were compared for extent (abdominal alone or extra-abdominal also) of disease and pattern of involvement (intestinal, peritoneal or both) and inflammatory response [serum C-reactive protein (CRP)]. RESULTS: Of 63 patients, 53 had complete data (mean age: 36.3 ± 14.43, 31 males). Fourty-five (84.9%) patients had VDD and mean VD levels were 11.1 ± 10.1 ng/ml. Of 8 patients with VDS, 1 (12.5%) had extra-abdominal involvement while 13 (28.9%) with VDD had extra-abdominal involvement (p = 0.066). The mean CRP in patients with VDD was 42.9 ± 34.9 mg/dl vis-a-vis 105.38 ± 64.8 in VDS (p ⩽ 0.05). All seven patients with both intestinal and peritoneal involvement had VDD. CONCLUSION: VDD is common in abdominal tuberculosis and may be associated with more extensive involvement albeit a reduced inflammatory response.
RESUMO
ABSTRACT Background Procalcitonin may be increased in active ulcerative colitis (UC). We investigated the role of procalcitonin in predicting response in acute severe UC (ASUC). Methods Consecutive patients with ASUC diagnosed on basis of Truelove and Witts criteria were enrolled. Serum procalcitonin levels for consecutive patients were measured at admission and day 3. We assessed role of procalcitonin values at presentation and at day 3 in assessing response on day 3 (Oxford's criteria) and need for second line therapy (day 28). Results Of fifty patients (23 males, mean age: 35.98±13.8 years), 16 did not respond (day 3). Ten (20%) patients required second-line therapy. Baseline procalcitonin was significantly associated with response on day 3 (P=0.016). There was no association between day 1 or day 3 procalcitonin and need for second-line rescue therapy. Conclusion Serial procalcitonin is not an effective biomarker for predicting outcomes or need for second line therapy in ASUC.
RESUMO Contexto A procalcitonina pode estar aumentada em colite ulcerativa ativa. Investigamos o papel da procalcitonina na previsão de resposta na colite ulcerativa aguda grave. Métodos Foram inscritos pacientes consecutivos com colite ulcerativa aguda grave diagnosticados com base nos critérios de Truelove e Witts. Os níveis de procalcitonina sérica dos pacientes foram medidos consecutivamente na internação e no terceiro dia. Avaliamos o papel dos valores procalcitonina na apresentação e na avaliação da resposta no terceiro dia (critérios de Oxford) e necessidade de terapia de segunda linha (dia 28). Resultados Dos 50 pacientes (23 homens, idade média: 35,98±13,8 anos), 16 não responderam (terceiro dia). Dez pacientes (20%) necessitaram de terapia de segunda linha. A procalcitonina de linha de base foi significativamente associada à resposta no terceiro dia (P=0,016). Não houve associação entre o primeiro dia ou o terceiro dia de procalcitonina e necessidade de terapia de resgate de segunda linha. Conclusão A procalcitonina sérica não é um biomarcador eficaz para prever desfechos ou necessidade de terapia de segunda linha em colite ulcerativa aguda grave.
RESUMO
OBJECTIVES: To analyze the morphological changes in bile ducts following endobiliary stent insertion, and consequent technical problems encountered at surgery. METHODS: Data on bile duct morphology--gross (luminal diameter and wall thickness) and microscopic (histological changes in bile duct wall graded semiquantitatively)--and operative parameters related to bile duct dissection (grade of difficulty in dissection) were collected prospectively in 31 consecutive patients undergoing pancreatico-duodenectomy. These data were compared between patients who had undergone preoperative endoscopic biliary stent placement (n=17) and those who had not (n=14). RESULTS: Mean duration of stenting before surgery was 34 (range 10-120) days. Stented ducts were significantly narrower (luminal diameter 9 [7-12] mm vs. 17.5 [8-23] mm; p=0.0001) and had thicker walls (2.3 [1.3-3.5] mm vs. 1.85 [0.8-2.2] mm; p=0.004) compared to non-stented ones. On microscopy, stented ducts had advanced grades of submucosal gland hypertrophy, fibrosis and inflammatory cell infiltrate. Difficulty in bile duct dissection was encountered more often in patients who had been stented than in those without stents, though the difference was not statistically significant. CONCLUSION: Endobiliary stent placement results in significant morphological and fibroproliferative inflammatory changes in bile ducts, making dissection difficult.
