Clinical analysis of 252 patients with tuberculous peritonitis in Wuhu area / 中华临床感染病杂志

Objective:To analyze the clinical features of tuberculous peritonitis (TBP).Methods:The clinical data of 252 TBP patients admitted to three hospitals in Wuhu area from January 2014 to June 2020 were retrospectively analyzed, and the clinical characteristics of TBP patients of different genders and ages were compared. SPSS 26.0 software was used to analyze the data.Results:Among 252 TBP patients, 130 were males (51.6%) and 122 were females (48.4%). History of abdominal surgery, abdominal masses, reproductive disorders, genital tuberculosis, and delay in diagnosis were more common in female patients (all P<0.01); while fever, cough/sputum expectoration, intestinal tuberculosis and active tuberculosis were more common in male patients (all P<0.01). The proportion of adenosine deaminase in ascites (ADA) ≥35 U/L, strong positive tuberculin test or T-cell spot test in middle-aged and elderly patients was lower than that in young patients ( P<0.01), but there was no significant difference between different genders. Compared with young patients, middle-aged and elderly patients had a low complete response rate, a high proportion of irregular medications, a high incidence of gastrointestinal reactions, liver damage and overall adverse reactions (all P<0.05). Conclusion:Female patients with TBP have fewer symptoms of systemic tuberculosis and high rate of delay in diagnosis, and are prone to complicated with reproductive tuberculosis. In middle-aged and elderly patients with TBP, the sensitivity of ADA and tuberculosis tests is decreased, and the anti-tuberculosis therapy is less effective. The study indicates that the clinical diagnosis and treatment of TBP should be optimized based on the gender and age of patients.

Primary Malignant Mesothelioma of the Peritoneum Mistaken for Peritoneal Tuberculosis due to Elevated Cancer Antigen 125 / 대한소화기학회지

A differential diagnosis of ascites is always challenging for physicians. Peritoneal tuberculosis is particularly difficult to distinguish from peritoneal carcinomatosis because of the similarities in clinical manifestations and laboratory results. Although the definitive diagnostic method for ascites is to take a biopsy of the involved tissues through laparoscopy or laparotomy, there are many limitations in performing biopsies in clinical practice. For this reason, physicians have attempted to find surrogate markers that can substitute for a biopsy as a confirmative diagnostic method for ascites. CA 125, which is known as a tumor marker for gynecological malignancies, has been reported to be a biochemical indicator for peritoneal tuberculosis. On the other hand, the sensitivity of serum CA 125 is low, and CA 125 may be elevated due to other benign or malignant conditions. This paper reports the case of a 66-year-old male who had a moderate amount of ascites and complained of dyspepsia and a febrile sensation. His abdominal CT scans revealed a conglomerated mass, diffuse omental infiltration, and peritoneal wall thickening. Initially, peritoneal tuberculosis was suspected due to the clinical symptoms, CT findings, and high serum CA 125 levels, but non-specific malignant cells were detected on cytology of the ascitic fluid. Finally, he was diagnosed with primary malignant peritoneal mesothelioma after undergoing a laparoscopic biopsy.

Shear wave elastography guided biopsy in diagnosis of tuberculous peritonitis / 中国介入影像与治疗学

Objective To assess the clinical value of ultrasound shear wave elastography (SWE) guided biopsy for diagnosis of tuberculous peritonitis.Methods Clinical data of 25 tuberculous peritonitis patients who underwent SWE guided biopsy (SWE guided group) and other 25 tuberculous peritonitis patients who underwent conventional ultrasound guided biopsy (conventional ultrasound guided group) were retrospectively analyzed.The successful rate of biopsy and the complication occurrence were compared between the two groups.Results The success rate of SWE guided group was 100％(25/25),and the rate of complication occurrence was 8.00％ (2/25).The successful rate and complication occurrence in conventional ultrasound guided group was 84.00％ (21/25) and 32.00％ (8/25),respectively.There were statistical differences of success rate of biopsy (x2=4.348,P=0.037) and the complication occurrence (x2=4.500,P=0.034) between the two groups.Conclusion Compared with conventional ultrasound,SWE guidance can improve the success rate and reduce the complication occurrence of biopsy.

Abdomen agudo por peritonitis tuberculosa. Presentación de un caso / Abdomen agudo por peritonitis tuberculosa. Presentación de un caso

La tuberculosis extrapulmonar es una infección bacteriana que se encuentra fuera del parénquima pulmonar. Es producida por diferentes tipos de mycobacterium, siendo el agente causal más frecuente en el ser humano el Mycobacterium tuberculosis. Se presenta el caso de una paciente angolana de 17 años, atendida en un hospital municipal en Angola, por presentar dolor intenso en todo el abdomen con reacción peritoneal generalizada. Se le realizaron varios exámenes que no esclarecieron el cuadro. Finalmente fue sometida a cirugía, en la cual se tomó biopsia del epiplón. El estudio histológico informó la presencia de granulomas tuberculoides, por lo que se diagnosticó una tuberculosis miliar. Los casos de abdomen agudo por peritonitis tuberculosa, son escasamente tratados por su poca frecuencia, de hecho, es el primero en cuarenta años de experiencia como cirujano del autor.

Extrapulmonary tuberculosis is a bacterial infection that occurs outside the lung parenchyma. It is caused by different types of mycobacteria; the most common causative agent in humans is Mycobacterium tuberculosis. The case of a 17-year-old Angolan patient treated in a municipal hospital in Angola due to severe abdominal pain with generalized peritoneal reaction is presented. Several tests were performed, but they did not clarify the patient’s condition. Finally, she underwent surgery and an omental biopsy was taken. The histological study revealed the presence of tuberculoid granulomas, which led to the diagnosis of miliary tuberculosis. Cases of acute abdomen due to tuberculous peritonitis are very uncommon, in fact, this is the first case seen by the author of this report in forty years practicing as a surgeon.

Coexistence of Myxedema Ascites and Tuberculous Peritonitis: a Case Report and Literature Review / 대한내과학회지

Some patients have ascites without having liver disease, so it is important to analyze the cause of these ascites. Tuberculous peritonitis is an infectious disease characterized by lymphocyte-dominant exudative ascites. In contrast, myxedema ascites is a very rare disease characterized by a high serum/ascites albumin gradient (SAAG) with hypothyroidism. We herein report a case involving a 48-year-old woman with both diseases simultaneously. She was hospitalized because of massive ascites, generalized edema, and a puffy face. Hypothyroidism was confirmed by thyroid function tests. Her ascitic fluid had a high SAAG; no other specific findings were identified by cytology, culture, or computed tomography. Three months after initiating drug therapy for the hypothyroidism, the patient's systemic edema improved but the ascites recurred. Accordingly, diagnostic laparoscopy was performed, and tuberculous peritonitis was confirmed. As seen in this case, when myxedema ascites is associated with tuberculous peritonitis, an accurate diagnosis may be challenging.

A Case of Paradoxical Reaction Development during Antituberculosis Therapy / 대한소화기학회지

Paradoxical reaction during antituberculosis therapy is defined as aggravation of preexisting tuberculous lesions or the development of new lesions. A 24-year-old female college student diagnosed with abdominal and pulmonary tuberculosis presented with fever and abdominal pain after having been treated with antituberculosis agents for 4 months. Tuberculous mesenteric lymphadenitis was suspected on abdominal CT scan and enlarged necrotic abscess was also present. These findings were considered to be due to paradoxical reaction rather than treatment failure during antituberculosis treatment. Although laparoscopic bowel adhesiolysis and abscess drainage were performed, high fever and severe abdominal pain did not improve. However, the patient eventually made a completely recovery after corticosteroid therapy combined with antituberculosis agents. Herein, we report a case of paradoxical reaction which developed in a patient with abdominal and pulmonary tuberculosis during antituberculosis therapy.

Analysis of early warning indicators of tuberculous peritonitis in patients with cirrhotic ascites / 临床肝胆病杂志

Objective To analyze the early warning indicators of tuberculous peritonitis (TBP)in patients with cirrhotic ascites.Methods A retrospective analysis was performed on the clinical data of 62 patients with cirrhotic ascites hospitalized in the Second Affiliated Hospital of Chongqing Medical University from January 2010 to December 2012.The chi-square test and Mann-Whitney U test were used for uni-variate analysis,while the logistic regression model was used for multivariate analysis.Results There were significant differences between TBP group and non-TBP group in sex,history of primary peritonitis,erythrocyte sedimentation rate (ESR),serum tuberculosis antibody, percentage of lymphocytes in ascites (≥50%),and prothrombin activity (PTA)(P<0.05 for all).The odds ratios (ORs)of history of primary peritonitis,PTA,ESR,and percentage of lymphocytes in ascites (≥50%)for development of TBP in patients with cirrhotic ascites were 1.933,3.205,2.716,and 11.701,respectively (P<0.05 for all),and the areas under the receiver operating characteristic curve were 0.831,0.815,0.775,and 0.935,respectively (P<0.05 for all).Conclusion History of primary peritonitis,PTA,ESR,and per-centage of lymphocytes in ascites (≥50%)are the early warning indicators of TBP in patients with cirrhotic ascites;these early warning in-dicators,especially percentage of lymphocytes in ascites (≥50%),have good predictive values.

A Case of Peritoneal Tuberculosis Developed after Infliximab Therapy for Refractory RA / 결핵및호흡기질환

Recently, interferon gamma releasing assay has been recommended to compensate the tuberculin skin test (TST) for screening for latent tuberculosis infection (LTBI). Although it improved the detection of LTBI before treatment with tumor necrosis factor blocker, its application to immune suppressed patients is limited. We report a case of peritoneal tuberculosis (TB) developed in a patient who tested positive for TST and QuantiFERON-TB Gold (QFT-G) before infliximab therapy, to emphasize the importance of monitoring during treatment. A 52-year-old woman presented with abdominal distension. She had been diagnosed with seropositive rheumatoid arthritis six years ago. She had started taking infliximab six months ago. All screening tests for TB were performed and the results of all were negative. At admission, the results of repeated TST and QFT-G tests were positive. Histopathological examination confirmed peritoneal TB. The patient started anti-TB therapy and the symptoms were relieved.

Trans-gastric peritoneoscopy with technique of natural-orifice transluminal endoscopic surgery for diagnosis of tuberculosis peritonitis: a report of 20 cases / 中华消化内镜杂志

Objective To investigate the diagnostic value of trans-gastric peritoneoscopy with technique of natural orifice transluminal endoscopic surgery(NOTES)for tuberculosis peritonitis.Methods Clinical data of 20 patients with tuberculosis peritonitis diagnosed by trans-gastric peritoneoscopy via NOTES were retrospectively analyzed.Results All diagnoses were confirmed by biopsy.The findings of peritoneoscopy were defined as miliary type with miliary nodes scattered in ascites and on peritoneum,adhesive type with thickening of peritoneum and adhesion between peritoneum and intestines,cheese-like type with parietal peritoneal ulcer and cheese-like substances,and mixed type with 2 or 3 of above mentioned types.Positive findings in other laboratory examinations were hemoglobin decrease in 10(50％)patients,blood sedimentation rate increase in 16(80％),C reactive protein increase in 13(65％),CA125 increase in 18(90％),and positive tuberculin test in 9(45％).Abnormal findings were detected by chest X-ray in 8(40％)patients,by abdominal ultrasonography examination in 2(10％),by abdominal CT in 7(35％),and by colonoscopy in 1(5％).No abnormal results were found in all patients in anti-tuberculosis antibody test,ascites bacteria culture and gastroscopy.Conclusion Trans-gastric peritoneoscopy via NOTES with biopsy is effective for diagnosis of tuberculosis peritonitis.

Peritoneal tuberculosis mimicking advanced ovarian carcinoma in elderly women:three case reports and literature review / 中华老年医学杂志

Objective To document peritoneal tuberculosis mimicking ovarian malignancy in elderly post-menopausal women and to review pertinent literature.Methods The records of 3 women with peritoneal tuberculosis who were managed at Beijing Hospital from January 2003 to September 2009 were reviewed.Results Three patients with peritoneal tuberculosis mimicking ovarian malignancy all presented with the classical symptoms of advanced-stage ovarian carcinoma,including ascites,abdominopelvic masses,elevated serum CA125,bloating and progressive emaciation.Two patients received laparotomy revealing peritoneal tuberculosis but no malignancy.All the patients were treated with anti-tuberculosis chemotherapy.Conclusions Medical awareness of peritoneal tuberculosis is still lacking and many women with this disease are initially thought to have ovarian malignancy and undergo unnecessary extended surgery.Laparoscopy including biopsies seems to be a sufficient and safe method to provide diagnosis of peritoneal tuberculosis.If laparoscopy is not feasible,laparotomy should be performed.Ascites and high level of CA125 do not necessarily indicate that the clinical picture is malignant in post-menopausal women.

A Tuberculous Peritonitis Presenting as Submucosal Tumors

Tuberculous peritonitis is not an uncommon disease, but the diagnosis is often missed and delayed because of the variability of disease presentation and non-specific clinical manifestations. In this report, we discuss a rare case of tuberculous peritonitis which presented as a submucosal mass in the colon. A 61-year-old woman registered at our hospital for a physical check-up. She had a weight loss of 3 kg over the past 6 months. The colonoscopic findings showed submucosal lesions (4 and 6 mm in size, yellow in color, and hard) which were suspected to be a carcinoid tumor. However, an abdomen-pelvic CT scan and laparoscopic findings suggested peritoneal tuberculosis. The result of laparoscopic biopsies was chronic granulomatous inflammation without caseous necrosis. After the standard anti-tuberculosis medications for 6 months, the previous lesions on the CT scan had resolved.
