RESUMO
Tuberculosis(TB) is a serious infection that affects transplant recipients, particularly in high TB burden countries. Clinical presentation of these patients is atypical, and the care and management are frequently tricky as multi-drug interaction and intolerable adverse effects. Contezolid, a novel oxazolidinone antibacterial agent, had been demonstrated to be effective for TB in vitro and had been shown in some clinical cases with a more favorable safety profile than linezolid, the first-generation oxazolidinone, which had a commonly seen myelosuppression and neuropathy. Additionally, Contezolid has a unique metabolic mechanism that leads to less drug interaction. Here, we report a case of multi-system TB in a transplant recipient with chronic kidney allograft dysfunction. She was intolerant to most first and second-line anti-TB drugs and repeatedly developed ascites and nocturnal low-grade fever. She finally achieved good efficacy and safety results after enhanced anti-TB treatment with the addition of contezolid. Given the increased risk of TB in patients with organ transplantation and multi-drug interaction in patients with severe comorbidities, further clinical studies are needed to investigate the application and appropriate dosage of contezolid in patients with active TB.
RESUMO
Tuberculous peritonitis (TB peritonitis) is one of the most challenging forms of extrapulmonary TB to diagnose. While tumor markers can be elevated in patients with TB peritonitis, FDG-PET/CT can aid in distinguishing TB peritonitis from malignancies, if an apron-like omentum pattern is seen. Laparoscopy is crucial for accurate and early diagnosis.
RESUMO
BACKGROUND: Interval appendectomy is widely recommended for patients with abscesses due to perforated appendicitis. A concomitant malignancy-related problem was reported after conservative treatment of acute appendicitis with abscess, but perforated appendicitis-associated tuberculous peritonitis was never reported. CASE PRESENTATION: A 67-year-old male patient with a laryngeal cancer history presented to our hospital with an acute appendicitis-associated ileal abscess. He was scheduled for an interval appendectomy after conservative treatment. Fortunately, the symptoms subsided, and the patient was discharged for a later scheduled appendectomy. However, after 3 months, he was readmitted to our hospital with fever and abdominal pain, and emergency surgery was performed, which was suspected to be peritonitis. Intraoperative results revealed numerous white nodules in the abdominal cavity. The condition was diagnosed as tuberculous peritonitis based on macroscopic results, later pathological findings, and positive T-SPOT.TB. The antituberculosis medications were effective, and the patient recovered and was discharged from the hospital 8 days thereafter. CONCLUSION: Patients, particularly those immunocompromised, may develop tuberculous peritonitis after conservative treatment for acute perforated appendicitis.

A 49-year-old man was admitted with peritonitis nine months after starting continuous ambulatory peritoneal dialysis (CAPD) for kidney failure. Ceftazidime and cefazolin were started. Peritoneal dialysate culture was negative for bacteria, but antibiotic treatment was continued because peritonitis improved. Twenty days later, the patient was discharged with no signs of peritonitis. However, 40-day culture of the original peritoneal dialysate detected Mycobacterium tuberculosis, and peritonitis recurred, leading to readmission. A T-SPOT test was performed and was positive in 4 days. Anti-tuberculosis therapy was started, which cured the peritonitis. The T-SPOT test may enable early diagnosis of tuberculosis.
RESUMO
Background: Fallopian tubal tuberculosis (FTTB), which typically presents with non-specific clinical symptoms and mimics ovarian malignancies clinically and radiologically, often affects young reproductive females and can lead to infertility if not promptly managed. Early diagnosis by imaging modalities is crucial for initiating timely anti-tuberculosis (anti-TB) treatment. Currently, comprehensive radiological descriptions of this relatively rare disease are limited. We aimed to comprehensively investigate the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of FTTB in patients from the Kashi area, which has the highest incidence of TB in China, to extend radiologists' understanding of this disease. Methods: We conducted a retrospective cross-sectional study of 26 patients diagnosed with FTTB at the First People's Hospital of Kashi Area. All the patients underwent abdominal and pelvic contrast-enhanced CT examinations and/or pelvic contrast-enhanced MRI from January 2017 to June 2022. The imaging findings were evaluated in consensus by two experienced radiologists specialized in abdominal and pelvic imaging. The evaluated sites included the fallopian tubes, ovaries, peritoneum, mesentery, retroperitoneal nodes, and parailiac nodes. The patient characteristics are reported using descriptive statistics. The patient imaging results are presented as percentages. The normally distributed continuous variables are reported as the mean ± standard deviation (SD), and otherwise as the median with the interquartile range (IQR). Results: The median age of the patients was 27 years (IQR: 25-34 years). Bilateral involvement of the fallopian tubes was observed in all patients. The tubal wall appeared coarse with tiny intraductal nodules in 96% (25 of 26) of the patients. The mean CT value of the tubal contents was 34 Hounsfield units (HUs; SD: 3.3 HUs). Ascites was present in 92% (24 of 26) of the patients, with 20 patients showing encapsulated effusion. Among these patients, 20 exhibited the highest CT values of ascites (>20 HUs). Linear enhancement of the parietal peritoneum was observed in 88% (23 of 26) of the patients, of whom 22 had peritoneal nodules measuring a median diameter of 0.4 cm (IQR: 0.3-0.6 cm). Eight patients had retroperitoneal and parailiac nodal enlargement, of whom two showed nodal necrosis, and none displayed nodal calcification. Conclusions: FTTB is consistently accompanied by tuberculous peritonitis. FTTB typically presents with tubal dilation, and coarseness and nodules in the lumen, as well as intraductal caseous material and calcification. Tuberculous peritonitis exhibits high-density ascites, peritoneal adhesion, linear enhancement of the parietal peritoneum, and tiny peritoneal nodules. The co-occurrence of these features strongly suggests a diagnosis of FTTB.
RESUMO
It is challenging to differentiate between tuberculous peritonitis and peritoneal carcinomatosis due to their insidious nature and intersecting symptoms. Computed tomography (CT) is the modality of choice in evaluating diffuse peritoneal disease. We conducted an ambispective analysis of patients suspected as having tuberculous peritonitis or peritoneal tuberculosis between Jan 2020 to Dec 2021. The study aimed to identify the clinical and radiological features differentiating the two entities. We included 44 cases of tuberculous peritonitis and 45 cases of peritoneal carcinomatosis, with a median age of 31.5 (23.5-40) and 52 (46-61) years, respectively (p ≤ 0.001). Fever, past history of tuberculosis, and loss of weight were significantly associated with tuberculous peritonitis (p ≤ 0.001, p = 0.038 and p = 0.001). Pain in the abdomen and history of malignancy were significantly associated with peritoneal carcinomatosis (p = 0.038 and p ≤ 0.001). Ascites was the most common radiological finding. Loculated ascites, splenomegaly and conglomeration of lymph nodes predicted tuberculous peritonitis significantly (p ≤ 0.001, p = 0.010, p = 0.038). Focal liver lesion(s) and nodular omental involvement were significantly associated with peritoneal carcinomatosis (p = 0.011, p = 0.029). The use of clinical features in conjunction with radiological findings provide better diagnostic yields because of overlapping imaging findings.
RESUMO
PURPOSE: To evaluate the diagnostic value of serum CA125 combined with 18F-FDG PET/CT in ovarian cancer (OC) and tuberculous peritonitis (TBP) in female patients and to establish a diagnostic scoring system. METHOD: A total of 86 female patients (64 OC and 22 TBP) were included in this study. Serum CA125, PET/CT maximal intensity projection (MIP), maximal standardized uptake value, ovarian mass, ascites volume, and other indicators were analyzed and a diagnostic scoring system was established according to the weights of statistically significant indicators. RESULTS: Univariate analysis showed that serum CA125 in OC and TBP patients were 2079.9 ± 1651.3 U/mL and 448.3 ± 349.5 U/mL (P < 0.001). In MIP images, abdominal lesions were focal distribution in 92.2% (59/64) of OC patients and diffuse distribution in 95.5% (21/22) of TBP patients (P < 0.001). Ovarian masses could be observed in 82.8% (53/64) OC patients and 31.8% (7/22) TBP patients (P <0.001). The other indicators were not statistically significant. Logistic regression analysis showed that serum CA125 and MIP were independent risk factors for diagnosis. A diagnostic scoring system could be established based on serum CA125, MIP and ovarian mass, and the diagnostic sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were 98.4% (63/64), 95.5% (21/22), 97.7% (84/86), 98.4% (63/64), and 95.5% (21/22), respectively. CONCLUSION: Serum CA125 combined with PET/CT is of great value in the diagnosis of OC and TBP. A simple and efficient diagnostic scoring system can be established using serum CA125, MIP image feature, and ovarian mass.
RESUMO
BACKGROUND: Tuberculous peritonitis is difficult to diagnose due to its non-specific clinical manifestations and lack of proper diagnostic modalities. Current meta-analysis was performed to find the overall diagnostic accuracy of adenosine deaminase (ADA) in diagnosing tuberculous peritonitis. MATERIALS AND METHODS: PubMed, Google Scholar, and Cochrane library were searched to retrieve the published studies which assessed the role of ascitic fluid ADA in diagnosing tuberculous peritonitis from Jan 1980 to June 2022. This meta-analysis included 20 studies and 2,291 participants after fulfilling the inclusion criteria. RESULTS: The pooled sensitivity was 0.90 (95% confidence interval [CI]: 0.85 - 0.94) and pooled specificity was 0.94 (95% CI: 0.92 - 0.95). The positive likelihood ratio was 15.20 (95% CI: 11.70 - 19.80), negative likelihood ratio was 0.10 (95% CI: 0.07 - 0.16) and diagnostic odds ratio was 149 (95% CI: 86 - 255). The area under the summary receiver operating characteristic curve was 0.97. Cut- off value and sample size were found to be the sources of heterogeneity in the mete-regression analysis. CONCLUSION: Ascitic fluid ADA is a useful test for the diagnosis of tuberculous peritonitis with good sensitivity and specificity however, with very low certainty of evidence evaluated by Grading of Recommendations, Assessment, Development and Evaluation approach. Further well- designed studies are needed to validate the diagnostic accuracy of ascitic fluid ADA for tuberculous peritonitis.
RESUMO
Abdominal tuberculosis is an ancient problem with modern nuances in diagnosis and management. The two major forms are tuberculous peritonitis and gastrointestinal tuberculosis (GITB), while the less frequent forms are esophageal, gastroduodenal, pancreatic, hepatic, gallbladder and biliary tuberculosis. The clinicians need to discriminate the disease from the close mimics: peritoneal carcinomatosis closely mimics peritoneal tuberculosis, while Crohn's disease closely mimics intestinal tuberculosis. Imaging modalities (ultrasound, computed tomography, magnetic resonance imaging and occasionally positron emission tomography) guide the line of evaluation. Research in diagnostics (imaging and endoscopy) has helped in the better acquisition of tissue for histological and microbiological tests. Although point-of-care polymerase chain reaction-based tests (e.g. Xpert Mtb/Rif) may provide a quick diagnosis, these have low sensitivity. In such situations, ancillary investigations such as ascitic adenosine deaminase and histological clues (granulomas, caseating necrosis, ulcers lined by histiocytes) may provide some specificity to the diagnosis. A diagnostic trial of antitubercular therapy (ATT) may be considered if all diagnostic armamentaria fail to clinch the diagnosis, especially in TB-endemic regions. Objective evaluation with clear endpoints of response is mandatory in such situations. Early mucosal response (healing of ulcers at two months) and resolution of ascites are objective criteria for early response assessment and should be sought at two months. Biomarkers, especially fecal calprotectin for intestinal tuberculosis, have also shown promise. For most forms of abdominal tuberculosis, six months of ATT is sufficient. Sequelae of GITB may require endoscopic balloon dilatation for intestinal strictures or surgical intervention for recurrent intestinal obstruction, perforation or massive bleeding.

Intraperitoneal ascites is a consequence or combination of many different underlying diseases. Laparoscopy with peritoneal biopsy is a tool for rapid and accurate diagnosis. Methods: We retrospectively identified patients who could not be diagnosed by clinical examination, laboratory investigations, and imaging tests. Results: A total of 103 (55 male and 48 female) patients were selected. The median age of the study group was 54 years (range 38-64 years). Typical clinical symptoms included fever (58.2%), abdominal pain (56.3%), and digestive disorders (62.1%). Fever and digestive disorders were higher in the peritoneal tuberculosis (TB) group than in the metastatic cancer group [(62.1% vs. 12.5%, P=0.009) and (66.3% vs. 12.5%, P=0.004)]. Abdominal pain was more common in the metastatic cancer group than in the other groups (100% vs. 55.8%, P=0.020). Patients in the TB and chronic inflammation groups had lower red blood cell counts and blood albumin (41 vs. 42, P=0.039) than those in the metastatic cancer group, respectively. The rate of intestinal wall thickening on ultrasound and peritoneal thickening on computed tomography was higher in the cancer group than in the benign group (87.5% vs. 7.4%, P=0.000) (75% vs. 23.2%, P=0.005), respectively. There was no difference in the median peritoneal fluid volume between the two groups (390 vs. 340, P=0.058). Pathological results showed 88.3%, 7.8%, and 3.9% of peritoneal TB, metastatic cancer, and chronic inflammatory lesions, respectively. The median hospital stay did not differ between the two groups (4 vs. 3 days, P=0.051). Both groups of patients had no morbidity or mortality. Conclusion: Unidentified ascites and peritonitis must be difficult for making diagnose by conventional methods. Laparoscopy might be supportive of making a rapid diagnosis and starting early treatment.
RESUMO
BACKGROUND: Gastrointestinal strictures impact clinical presentation in abdominal tuberculosis and are associated with significant morbidity. AIM: To conduct a systematic review of the prevalence of stricturing disease in abdominal and gastrointestinal tuberculosis and response to antitubercular therapy (ATT). METHODS: We searched Pubmed and Embase on 13th January 2022, for papers reporting on the frequency and outcomes of stricturing gastrointestinal tuberculosis. The data were extracted, and pooled prevalence of stricturing disease was estimated in abdominal tuberculosis and gastrointestinal (intestinal) tuberculosis. The pooled clinical response and stricture resolution (endoscopic or radiologic) rates were also estimated. Publication bias was assessed using the Funnel plot and Egger test. The risk of bias assessment was done using a modified Newcastle Ottawa Scale. RESULTS: Thirty-three studies reporting about 1969 patients were included. The pooled prevalence of intestinal strictures in abdominal tuberculosis and gastrointestinal TB was 0.12 (95%CI 0.07-0.20, I2 = 89%) and 0.27 (95% CI 0.21-0.33, I2 = 85%), respectively. The pooled clinical response of stricturing gastrointestinal tuberculosis to antitubercular therapy was 0.77 (95%CI 0.65-0.86, I2 = 74%). The pooled stricture response rate (endoscopic or radiological) was 0.66 (95%CI 0.40-0.85, I2 = 91%). The pooled rate of need for surgical intervention was 0.21 (95%CI 0.13-0.32, I2 = 70%), while endoscopic dilatation was 0.14 (95%CI 0.09-0.21, I2 = 0%). CONCLUSION: Stricturing gastrointestinal tuberculosis occurs in around a quarter of patients with gastrointestinal tuberculosis, and around two-thirds of patients have a clinical response with antitubercular therapy. A subset of patients may need endoscopic or surgical intervention. The estimates for the pooled prevalence of stricturing disease and response to ATT had significant heterogeneity.

BACKGROUND: The sensitivity of single abdominal paracentesis for diagnosis of peritoneal carcinomatosis (PC) varies from 40-70%. We hypothesized that rolling-over the patient before paracentesis might improve the cytological yield. RESEARCH DESIGN AND METHODS: This was a single center pilot study with a randomized cross-over design. We compared the cytological yield of fluid obtained by roll-over technique (ROG) with standard paracentesis (SPG) in suspected PC. In the ROG group, patients were rolled side-to-side thrice, and the paracentesis was done within 1 minute. Each patient served as their own control, and the outcome assessor (cytopathologist) was blinded. The primary objective was to compare the tumor cell positivity between SPG and ROG groups. RESULTS: Of 71 patients, 62 were analyzed. Of 53 patients with malignancy-related ascites, 39 had PC. Most of the tumor cells were adenocarcinoma (30, 94%) with one patient each having suspicious cytology and one having lymphoma. The sensitivity for diagnosis of PC was (31/39) 79.49% in SPG group and (32/39) 82.05% in ROG group (p = 1.00). The cellularity was similar between both the groups (good cellularity in 58% of SPG and 60% of ROG, p = 1.00). CONCLUSIONS: Rollover paracentesis did not improve the cytological yield of abdominal paracentesis. TRIAL REGISTRATION: CTRI/2020/06/025887 and NCT04232384.

INTRODUCTION: Tuberculous peritonitis (TBP) is a rare but fatal complication in patients on peritoneal dialysis (PD). In this study, we aimed to determine the demographic features, clinical features, laboratory parameters, and clinical outcomes of PD patients with TBP and to clarify possible risk factors for mortality. MATERIALS AND METHODS: We retrospectively reviewed 2084 PD patients from January 1985 to December 2019. The diagnosis of TBP was established by positive peritoneal fluid culture for Mycobacterium tuberculosis. RESULTS: 18 patients were diagnosed with TBP. The incidence was 2.029 episodes per 1000 patient-years. The most common symptom was fever (94.4%), followed by cloudy effluent (83.3%) and abdominal pain (83.3%). The average peritoneal dialysis effluent (PDE) white blood cell (WBC) count was 172.7 cells/µL. Nine patients (50%) had WBC counts lower than 100 cells/µL and 13 patients (72.2%) had neutrophilic predominant WBC counts. Acid fast stain (AFS) was positive in 7 patients (38.9%). Only 2 patients (11.1%) continued with PD after TB infection, while 10 patients (55.6%) changed to hemodialysis. Seven patients (38.9%) died within 1 year. Significant differences were observed in sex (p = 0.040), the presence of diabetes mellitus (p = 0.024), and PD catheter removal (p < 0.001) between TBP patients with and without mortality. However, none of them was a significant factor for 1-year mortality in multivariate Cox regression model. CONCLUSION: Physicians should pay attention to the unusual presentations of peritonitis, especially if symptoms include fever or an initial low PDE WBC count. Catheter removal is not mandatory if early diagnosis and appropriate therapy are available.

Introduction: Diagnosis of tuberculous peritonitis (TBP) requires a high index of suspicion. Hypothesis /gap statement: Information about the diagnostic features of TBP among patients with end-stage renal failure (ESRF) from India is limited. Aim: To assess the utility of the Gene Xpert MTB/RIF assay in the diagnosis of TBP in patients with end-stage renal failure (ESRF), compared with those without ESRF. Methodology: This prospective observational single centre cohort study was performed at a tertiary care centre in Northern India. Ascitic fluid and/or whole continuous ambulatory peritoneal dialysis (CAPD) bag with effluent from 300 clinically suspected cases of TBP were included in the study. Diagnosis was based on detection of Mycobacteria on smear, Xpert MTB/RIF assay and/or culture. Cell counting was done in a Neubauer chamber. Cell predominance was seen by Giemsa stain. Line probe assay (LPA) for drug susceptibility testing was performed on all positive cultures. Results: TBP was diagnosed in 168 cases. Diabetes mellitus was a significant risk factor for developing TBP in patients with ESRF (P value<0.01). Lymphocytic predominance was seen in 21 patients without ESRF (P value 0.033) while majority of the patients in both groups had neutrophils in their ascitic and peritoneal fluids (138/168; P value 0.033). We recovered 15 cases of laboratory diagnosed TBP (11 without ESRF and four with ESRF). Microscopy was positive in two cases while ten isolates were recovered on culture. The Xpert MTB/RIF assay was positive in seven ascitic fluid samples out of which three were rifampicin resistant. All these were patients without renal failure (P value 0.010). Eight culture positive samples tested by the line probe assay did not detect any resistance to either rifampicin or isoniazid. Conclusion: The GeneXpert MTB/RIF assay has a limited value in the diagnosis of TBP in patients with ESRF.
RESUMO
BACKGROUND: Differential diagnosis between tuberculous peritonitis and peritoneal carcinomatosis remains challenging in clinical practice; thus, in-patients diagnosed with tuberculous peritonitis or peritoneal carcinomatosis were retrospectively enrolled, and diagnostic values of ascitic tumor markers and adenosine deaminase were determined. METHODS: Consecutive patients diagnosed with tuberculous peritonitis or peritoneal carcinomatosis were retrospectively enrolled. The pertinent data of 169 patients enrolled were collected. RESULTS: A panel of ascitic tumor makers (CEA, CA15-3, CA19-9) had high specificity (96.83%) and accuracy (94.67%) in the differentiation of peritoneal carcinomatosis from tuberculous peritonitis; and ascitic ADA was a good discriminator between these patients, with an accuracy of 91.72%. Combined use of ascitic tumor makers and ADA (ascitic ADA < 22.5 IU/L or ascitic CEA > 3.65 ng/mL or CA15-3 > 42.70 U/mL or CA19-9 > 25.10 U/mL) performed high sensitivity (99.06%) and accuracy (94.08%) for the diagnosis of peritoneal carcinomatosis. In addition, combined ascitic ADA and tumor marker (positive ascitic tumor makers and ADA < 22.50 IU/L) had 100% of the specificity in diagnosing peritoneal carcinomatosis. CONCLUSIONS: Combined use of ascitic tumor markers and adenosine deaminase showed excellent efficiency in the differential diagnosis between tuberculous peritonitis and peritoneal carcinomatosis, thus these two simple and cost-effective parameters should be determined when tuberculous peritonitis or peritoneal carcinomatosis was suspected in clinic practice.

BACKGROUND: Malignant peritoneal mesothelioma (MPM) is a rare malignancy arising in mesothelial cells in the peritoneum. It can be mistaken for many other diseases, such as peritoneal carcinomatosis and tuberculous peritonitis (TBP), because its clinical manifestations are often nonspecific. Therefore, the diagnosis of MPM is often challenging and delayed. CASE SUMMARY: A 42-year-old man was referred to our hospital with lower abdominal pain for 1 wk and ascites observed under abdominal sonography. His laboratory findings revealed an isolated elevated tumor marker of carcinoma antigen 125 (167.4 U/mL; normal, < 35 U/mL), and contrast enhanced computed tomography showed peritoneal thickening. Thus, differential diagnoses of TBP, carcinomatosis of an unknown nature, and primary peritoneal malignancy were considered. After both esophagogastroduodenoscopy and colonoscopy produced negative findings, laparoscopic intervention was performed. The histopathological results revealed mesothelioma invasion into soft tissue composed of a papillary, tubular, single-cell arrangement of epithelioid cells. In addition, immunohistochemical staining was positive for mesothelioma markers and negative for adenocarcinoma markers. Based on the above findings, TBP was excluded, and the patient was diagnosed with MPM. CONCLUSION: It is important to distinguish MPM from TBP because they have similar symptoms and blood test findings.
RESUMO
ABSTRACT Background: The role of ascitic and serum levels of various tumour biomarkers in the discrimination of cause of ascites is not well established. Objective: To evaluate the role of serum and ascitic levels of tumor biomarkers (CA 72-4, CA 19-9, CEA and CA 125) in discrimination of cause of ascites. Methods: A prospective study was conducted in consecutive patients presenting with ascites. Serum and ascitic levels of CA 19-9, CA 125, CA 72-4 and carcinoembryonic antigen (CEA) were determined at the presentation. The patients with cirrhotic ascites, tuberculous peritonitis (TBP) and peritoneal carcinomatosis (PC) were eventually included in analysis. Results: Of the 93 patients (58 males, mean age 47 years) included, the underlying cause was cirrhosis in 31, PC in 42 and peritoneal tuberculosis in 20. The best cutoff for discriminating benign and malignant ascites for serum CEA, CA 19-9 and CA 72-4 were 6.7 ng/mL, 108 IU/mL and 8.9 IU/mL, respectively. The best cutoff for discriminating benign and malignant ascites for ascitic CA 125, CEA, CA 19-9 and CA 72-4 were 623 IU/mL, 8.7 ng/mL, 33.2 IU/mL and 7 IU/mL, respectively. Conclusion: The performance of single biomarker for the prediction of underlying PC is low but a combination of serum CA 19-9 and CA 72-4 best predicted the presence of peritoneal carcinomatosis.
RESUMO Contexto: O papel dos níveis ascíticos e séricos de vários biomarcadores de tumores na discriminação da causa das ascites não está bem estabelecido. Objetivo: Avaliar o papel dos níveis séricos e ascíticos de biomarcadores tumorais (CA 72-4, CA 19-9, CEA e CA 125) na discriminação da causa das ascites. Métodos: Estudo prospectivo foi realizado em pacientes consecutivos que apresentaram ascite. Foram determinados níveis do soro e ascítico de CA 19-9, CA 125, CA 72-4 e antígeno carcinoembrínico (CEA). Os pacientes com ascites cirróticas, peritonite tuberculosa e carcinomatose peritoneal (CP) foram eventualmente incluídos na análise. Resultados: Dos 93 pacientes (58 homens, média de idade 47 anos) incluídos, a causa básica foi cirrose em 31, CP em 42 e tuberculose peritoneal em 20. O melhor corte para discriminação de ascites benignas e malignas para soro CEA, CA 19-9 e CA 72-4 foram 6,7 ng/mL, 108 UI/mL e 8,9 UI/mL, respectivamente. O melhor corte para discriminação de ascites benignas e malignas para CA 125 ascitico, CEA, CA 19-9 e CA 72-4 foram 623 UI/mL, 8,7 ng/mL, 33,2 UI/mL e 7 UI/mL, respectivamente. Conclusão: O desempenho do biomarcador único para a previsão do CP subjacente é baixo, mas uma combinação de soro CA 19-9 e CA 72-4 melhor previu a presença de carcinomatose peritoneal.
RESUMO
Abdominal tuberculosis (TB) can affect any organ of the gastrointestinal tract, and as a result of its unspecific symptoms, it may even mimic neoplasia. Rare manifestations are difficult to detect even for the trained eye and require clinical suspicion. We report rare cases of a mechanical ileus due to peritoneal TB in a 41-year-old man and an isolated peripancreatic infection in a 54-year-old woman. While in one patient, suspected malignancy led to diagnostic laparoscopy, it led to a total pancreatectomy with splenectomy in the other case. However, both times histology ruled out malignancy and showed unexpected similarities with TB. The patients responded well to medical treatment, although one patient is struggling with pancreatogenic diabetes.
RESUMO
INTRODUCTION: Budd-Chiari syndrome is a rare disease characterized by hepatic venous flow obstruction. The obstruction may be thrombotic or non-thrombotic anywhere along the venous course from the hepatic venules to the inferior vena cava (IVC) junction to the right atrium. In clinical practice, cases can be misdiagnosed, particularly in regions where resources are limited, unless the clinician pays special attention to such diagnosis. CASE REPORT AND CLINICAL DISCUSSION: Here, we would like to present a misdiagnosed case of Budd Chiari syndrome. This reported case is a case of 30 years old female patient complaining of dull abdominal pain and swelling. Initially, the patient consulted a local health facility where the patient was diagnosed with tuberculous peritonitis and subsequently treated with an anti-TB regimen empirically. Within a few days of taking medicine, she developed mild jaundice and lower limb edema. At this stage, the patient came to us, which after taking history, her physical examination unveiled mild jaundice, ascites, abdominal tenderness, and mild lower limb petting edema. The patient was recommended an abdominal CT scan with contrast, which revealed early enhancement and enlargement of the caudate lobe and non-opacification of hepatic veins with narrowing of the hepatic part of the inferior vena cava consistent with Budd-Chiari syndrome. The patient was started on warfarin and referred for a hepatic decongestive procedure. After four months of performing a transjugular portosystemic shunt, the patient came to us for follow-up. She had an excellent clinical improvement and was started on rivaroxaban 20 mg daily orally. CONCLUSION: The main takeaway lesson of this particular case is to consider the differential diagnosis of ascites from an etiologic point of view and not to overemphasize a single etiology.
