- Neurotuberculosis in a Patient with Ulcerative Colitis Using Long-Term Adalimumab: A Rare Case(2023) FACANALI, Carolina Bortolozzo Graciolli; FACANALI JUNIOR, Marcio Roberto; RIBEIRO, Adriana Vaz Safatle; SOBRADO JUNIOR, Carlos WalterObjective: Rare disease Background: Tuberculosis (TB), a global public health problem, is a disease with a high incidence and prevalence worldwide. The risk of developing TB increases after starting anti-tumor necrosis factor (TNF) therapy in the management of ulcerative colitis (UC). Isolated neurotuberculosis (NTB) without other manifestations is a rare form of infec-tion in these patients. This article reports a case of a severe UC patient with isolated NTB following long-term therapy with adalimumab and discusses the clinical aspects, diagnosis, management, and prognosis. Case Report: A 34-year-old female patient with severe UC with pancolitis reported continuous and progressive holocranial headaches associated with a daily fever of 38 degrees C and night sweats after 4 years of using adalimumab and af-ter being in deep remission. Annually, she was screened for latent TB with chest X-rays and a Mantoux tuber-culin skin test, and she always had negative results for TB. On cerebral magnetic resonance imaging with post -contrast sequences, small cortical lesions in the left frontal lobe and 2 larger lesions were visualized and were suggestive of tuberculomas. The initial management consisted of the suspension of immunosuppressive ther-apy and treatment with rifampicin, isoniazid, ethambutol, pyrazinamide, and prednisone. The patient showed clinical and neurological improvement and was clinically asymptomatic, with no changes in laboratory tests. Also, she had no neurological sequelae and was taking maintenance therapy with prednisone as indicated by the neurologist. Conclusions: Early recognition of symptoms of neurological involvement of TB, suspension of anti-TNF and adequate treat-ment are fundamental steps to prevent complications.
- Is there a higher frequency of anal dysplasia and infection by human papillomavirus in Crohn?s disease patients?(2022) GUZELA, V. R.; SOBRADO JR., C. W.; NADAL, S. R.; VILLA, L. L.; MOTA, G. R.; GONCALVES, A. P.; NADAL, C. R. M.; NAHAS, C. S. R.; NAHAS, S. C.The aim of this study was to compare the frequency of dysplasia and human papillomavirus (HPV) infection in the anal canal of patients with Crohn???s disease (CD) with a control group and assess whether there is a correlation between use of immunosuppressants and anal manifestation of CD. Patients with CD and control individuals were submitted to anal cytology and material collection for polymerase chain reaction (PCR). The cytology was classified as normal, atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LSIL), or high-grade (HSIL). PCR was considered positive or negative according to virus presence or absence. A total of 117 patients were included (54 in the control group and 63 in the CD group, being 32 without and 31 with immunosuppressants). ASCUS and LSIL were found in 25.9 and 22.2% of control patients and 28.6 and 39.7% of CD patients. HPV was identified in 14.8% of the control group and 27% of the CD group. In CD patients, HPV was found in 37.5 and 16.1% of those without and with immunosuppressants, respectively. Patients with perianal involvement had 15.6% of PCR positivity. There was no statistical difference in dysplasia and infection by HPV between the groups. Use of immunosuppressants did not influence the result, but anal manifestation was inversely proportional to viral detection.
- Gastric and Duodenal Fistulas in Crohn's Disease, a Surgical Challenge: Report of 5 Cases and a Review of the Literature(2023) SOBRADO JUNIOR, Carlos Walter; VILLELA JUNIOR, Helder de Moura; FACANALI, Carolina Bortolozzo Graciolli; SOBRADO, Lucas Faraco; CAMARGO, Mariane Gouvea Monteiro de; NAHAS, Sergio CarlosObjective: Rare diseaseBackground: Fistulas involving the stomach and duodenum in Crohn's disease are rare (occurring in less than 1% of patients). Here, we reviewed registers from 855 patients with Crohn's disease treated in our service from January 2007 to December 2020 and found 4 cases of duodenal fistula and 1 case of gastric fistula.Case Reports: The fistula origin was in the ileocolic segment in all cases, and all of the patients underwent preoperative optimization with improvement of nutritional status and infection control. They then underwent surgical treatment with resection of the affected segment and duodenal or gastric closure with covering by an omental patch. One case of a duodenal fistula was complicated by duodenal dehiscence. This was treated surgically with duodenojejunostomy. Each of the other patients had an uneventful postoperative course. All patients were successfully cured of their gastroduodenal fistulas, and at the time of this publication, none of them died or had fistula recurrence.Conclusions: Fistulas with the involvement of the stomach and duodenum in patients with Crohn's disease are almost always due to inflammation in the ileum, colon, or previous ileocolic anastomosis. Management of this situation is complex and often requires clinical and surgical assistance; preoperative optimization of the patient's general condition can improve the surgical results. The surgical approach is based on resection of the affected segment and gastric or duodenal closure with covering by an omental patch. Gastrojejunostomy or duodenojejunostomy can be performed in selected patients with larger defects and minor jejunal disease. To prevent recurrence, prophylactic therapy with anti-TNF agents and early endoscopic surveillance are also essential for successful treatment.
- The relationship of major depressive disorder with Crohn?s disease activity(2023) FACANALI, Carolina Bortolozzo Graciolli; SOBRADO JUNIOR, Carlos Walter; FRAGUAS JUNIOR, Renerio; FACANALI JUNIOR, Marcio Roberto; BOARINI, Lucas Rodrigues; SOBRADO, Lucas Faraco; CECCONELLO, IvanIntroduction: Crohn's disease (CD) has been related to an increased prevalence of psychiatric disorders and suicide risk (SR). However, the nature of their relationship still deserves clarification. The aim of this study is to assess the prevalence of major depressive disorder (MDD) in patients with CD, and to investigate the relationship between MDD and CD outcomes.Methods: A cross-sectional study involving CD patients was performed. CD activity was evaluated by the Harvey -Bradshaw index and CD phenotype by the Montreal classification. The presence of MDD was assessed by the Patient Health Questionnaire score-9 (PHQ-9). Sociodemographic data and other characteristics were retrieved from electronic medical records.Results: 283 patients with CD were included. The prevalence of MDD was 41.7%. Females had a risk of MDD 5.3 times greater than males. CD disease duration was inversely correlated with MDD severity. Individuals with active CD were more likely to have MDD (OR = 796.0; 95% CI 133.7-4738.8) than individuals with CD remis-sion. MDD was more prevalent in inflammatory behavior (45.5%) and there were no statistical differences regard-ing the disease location. 19.8% of the sample scored positive for SR.Conclusion: The present results support data showing an increased prevalence of MDD in individuals with CD. Additionally, it indicates that MDD in CD might be related to the activity of CD. Prospective studies are warranted to confirm these results and to address whether MDD leads to CD activity, CD activity leads to MDD or both ways are existent.
- The novel BPRST classification for hemorrhoidal disease: A cohort study and an algorithm for treatment(2021) SOBRADO, Carlos Walter; OBREGON, Carlos de Almeida; SOBRADO, Lucas Faraco; BASSI, Lucas Morales; HORA, Jose Americo Bacchi; SOUSA JUNIOR, Afonso Henrique Silva e; NAHAS, Sergio Carlos; CECCONELLO, IvanBackground: The classification for HD was developed by Goligher in 1980 and does not contemplate important aspects of this disease, which limits its use in guiding treatment. The aim of this study if to apply in clinical practice the new classification for hemorrhoids named BPRST (bleeding, prolapse, reduction, skin tags, thrombosis), to compare it with the original classification proposed by Goligher and to propose an algorithm for treatment. Materials and methods: This is a prospective study conducted at the University of Sao Paulo's teaching hospital and Hospital 9 de Julho. Patients with HD treated from March 2011 to July 2013 were included. Patients were classified according to BPRST and Goligher classifications and treated according to personal experience and most updated guidelines. The association between both classifications and the treatment adopted was compared and an algorithm for treatment was developed. Results: 229 patients were included in this study and 28 patients were lost due to follow-up. According to Goligher, 29, 61, 85 and 26 were classified as grades I, II, III and IV, respectively. According to the BPRST, 23 were classified as stage I, 95 as stage II and 83 as stage III. Six patients classified as Goligher I were reclassified as BPRST stage III and required conventional hemorrhoidectomy, either due to thrombosis (n = 4) or intolerable skin tags (n = 2). The BPRST classification was more closely associated with the type of treatment employed and had few outliers than Goligher (p < 0.001). Conclusion: There are limitations to the use of Goligher's classification in clinical practice. The novel BPRST classification includes important aspects of HD that should be considered when deciding the best treatment option. Our algorithm for treatment contemplates the most commonly used techniques and can help to guide the treatment of this complex disease.
- RISK FACTORS FOR EARLY POSTOPERATIVE COMPLICATIONS IN ACUTE ESFAGOGÁSTRICE ESPLENECTOMIA INFL COLITIS IN THE ERA OF BIOLOGIC THERAPY(2023) SOBRADO, Lucas Faraco; MORI, Fernando Noboru Cabral; FACANALI, Carolina Bortolozzo Graciolli; CAMARGO, Mariane Gouvea Monteiro; NAHAS, Sergio Carlos; SOBRADO, Carlos WalterBackground: Despite major advances in the clinical treatment of inflammatory bowel disease, some patients still present with acute colitis and require emergency surgery. Aims: To evaluate the risk factors for early postoperative complications in patients undergoing surgery for acute colitis in the era of biologic therapy. Methods: Patients with inflammatory bowel disease admitted for acute colitis who underwent total colectomy at a single tertiary hospital from 2012 to 2022 were evaluated. Postoperative complications were graded according to Clavien-Dindo classification (CDC). Patients with more severe complications (CDC >= 2) were compared with those with less severe complications (CDC<2). Results: A total of 46 patients underwent surgery. The indications were: failure of clinical treatment (n=34), patients' or surgeon's preference (n=5), hemorrhage (n=3), toxic megacolon (n=2), and bowel perforation (n=2). There were eight reoperations, 60.9% of postoperative complications classified as CDC >= 2, and three deaths. In univariate analyses, preoperative antibiotics use, ulcerative colitis diagnosis, lower albumin levels at admission, and preoperative hospital stay longer than seven days were associated with more severe postoperative complications. Conclusions: Emergency surgery for acute colitis was associated with a high incidence of postoperative complications. Preoperative use of antibiotics, ulcerative colitis, lower albumin levels at admission, and delaying surgery for more than seven days were associated with more severe early postoperative complications. The use of biologics was not associated with worse outcomes.
- A New Classification for Hemorrhoidal Disease: The Creation of the ""BPRST"" Staging and Its Application in Clinical Practice(2020) SOBRADO JUNIOR, Carlos Walter; OBREGON, Carlos de Almeida; SOUSA JUNIOR, Afonso Henrique da Silva e; SOBRADO, Lucas Faraco; NAHAS, Sergio Carlos; CECCONELLO, IvanPurpose: Present an updated classification for symptomatic hemorrhoids, which not only guides the treatment of internal hemorrhoids but also the treatment of external components. In addition, this new classification includes new treatment alternatives created over the last few years. Methods: Throughout the past 7 years, the authors developed a method to classify patients with symptomatic hemorrhoids. This study, besides presenting this classification proposal, also retrospectively analyzed 149 consecutive patients treated between March 2011 and November 2013 and aimed to evaluate the association between the management adopted with Goligher classification and our proposed BPRST classification. Results: Both classifications had a statistically significant association with the adopted management strategies. However, the BPRST classification tended to have fewer management discrepancies when each stage of disease was individually analyzed. Conclusion: Although there is much disagreement about how the classification of hemorrhoidal disease should be updated, it is accepted that some kind of revision is needed. The BPRST method showed a strong association with the management that should be adopted for each stage of the disease. Further studies are needed for its validation, but the current results are encouraging.
- Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV in the anorectal fistula tract. A comparative study(2023) BOARINI, Lucas Rodrigues; SOBRADO, Carlos Walter; MOTA, Giana Rabello; VILLA, Luisa Lina; ALBUQUERQUE, Idblan Carvalho de; QUEIROZ, Natalia Sousa Freitas; FACANALI, Carolina Bortolozzo Graciolli; NADAL, Sidney Roberto; CECCONELLO, IvanBackground & Aims: Perianal fistulizing Crohn's disease is the main risk factor for anal cancer in patients with inflammatory bowel disease. Whether this occurs due to a higher frequency of human papillomavirus remains unclear. The authors aimed to evaluate the prevalence of HPV and high-risk HPV in patients with perianal Crohn's disease, compared with a control group. Methods: The authors conducted a two-center cross-sectional study in which perianal fistulizing Crohn's disease patients were matched for age and sex with patients with anorectal fistula without Crohn's disease. Biopsy specimens were obtained from fistulous tracts during examination under anesthesia for both groups. The samples were sent for HPV detection and genotyping using the INNO-LiPA test. Results: A total of 108 subjects (54 in each group) were recruited. The perianal fistulizing Crohn's disease group showed a statistically higher frequency of HPV in the fistulous tract than the control group (33.3% vs. 16.7%; p = 0.046). Separate analyses on high-risk types demonstrated that there was a numerically higher frequency of HPV in the perianal fistulizing Crohn's disease group. In multiple logistic regression, patients with perianal fistulizing Crohn's disease were found to have a chance of HPV 3.29 times higher than patients without Crohn's disease (OR = 3.29; 95% CI 1.20-9.01), regardless of other variables. The types most frequently identified in the perianal fistulizing Crohn's disease group were HPV 11 (12.96%) and HPV 16 (9.26%). Conclusion: Perianal fistulizing Crohn's disease is associated with a higher prevalence of HPV than in patients with anorectal fistula without Crohn's disease.
- STAPLED HEMORRHDOPEXY: RESULTS,LATE COMPLICATIONS AND DEGREE OF SATISFACTION AFTER 16 YEARS OF FOLLOW-UP(2022) SOBRADO, Carlos Walter; SOBRADO, Lucas Faraco; OBREGON, Carlos Almeida; VILLELA, Helder Moura; HORA, Jose Americo BacchiBackground: Stapled hemorrhoidopexy has been widely used for the treatment of hemorrhoids, but concerns about complications and recurrences after prolonged follow-up are still under debate. Aims: The aim of this study was to evaluate the very long-term results of the stapled hemorrhoidopexy technique. Methods: Stapled hemorrhoidopexy was performed on 155 patients between 2000 and 2003, and the early results have already been published. In this study, we evaluated the same patients after a very long follow-up. Data were collected with regard to late complications, rate and timing of recurrences, and patients' degree of satisfaction. Results: From a total of 155 patients, 98 patients were evaluated: 59 (60.2%) were interviewed by telephone and 39 (39.8%) were evaluated by outpatient consultation. The mean follow-up was 193 months (range: 184-231), 52 were female, 52 were grade III hemorrhoids, and 46 were grade IV. Recurrence was higher in grade IV (26.1%) than in grade III (7.7%) (p=0.014). Recurrence after prolonged follow-up was seen in 16 patients (16.3%) and 11 (11.2%) required reoperations. The complications were skin tags (3.1%), anal sub-stenosis (2.1%), and fecal incontinence (2.1%). After a prolonged follow-up, 82.5% of patients were either very satisfied or satisfied with the surgery. Conclusions: Stapled hemorrhoidopexy is a safe and effective treatment for hemorrhoidal disease grades III and IV. Recurrence is higher for grade IV hemorrhoids and may occur up to 9 years of follow-up. Reoperations were infrequent and there is a high patient's degree of satisfaction associated with this technique.
- ANORECTAL MANOMETRY STANDARD OF A BRAZILIAN POPULATION AT PRODUCTIVE AGE WITHOUT PELVIC FLOOR DISORDERS: A PROSPECTIVE VOLUNTEERED STUDY(2021) PINTO, Rodrigo Ambar; CORREA-NETO, Isaac Jose Felippe; BUSTAMANTE-LOPEZ, Leonardo Alfonso; NAHAS, Caio Sergio R.; MARQUES, Carlos Frederico S.; SOBRADO-JUNIOR, Carlos Walter; CECCONELLO, Ivan; NAHAS, Sergio CarlosBackground: Due to the lack of normal standards of anorectal manometry in Brazil, data used are subject to normality patterns described at different nationalities. Aim: To determine the values and range of the parameters evaluated at anorectal manometry in people, at productive age, without pelvic floor disorders comparing the parameters obtained between male and female. Methods: Prospective analysis of clinical data, such as gender, age, race, body mass index (BMI) and anorectal manometry, of volunteers from a Brazilian university reference in pelvic floor disorders. Results: Forty patients were included, with a mean age of 45.5 years in males and 37.2 females (p=0.43). According to male and female, respectively in mmHg, resting pressures were similar (78.28 vs. 63.51, p=0.40); squeeze pressures (153.89 vs. 79.78, p=0.007) and total squeeze pressures (231.27 vs. 145.63, p=0.002). Men presented significantly higher values of anorectal squeeze pressures, as well as the average length of the functional anal canal (2.85 cm in male vs. 2.45 cm in female, p=0.003). Conclusions: Normal sphincter pressure levels in Brazilians differ from those used until now as normal literature standards. Male gender has higher external anal sphincter tonus as compared to female, in addition a greater extension of the functional anal canal
