Liver function tests before and after the treatments were performed once in 2 wk or monthly, and their clinical manifestations were recorded.RESULTS: The rate of hepatotoxicity occurred in 26 (59%)TB patients with HBV during anti-TB treatment, higher than that in 40 (24%) TB patients without HBV. Hepatotoxicity occurred in 66 out of 217 patients, and the incidence of liver dysfunction was 46.1% in HPBE(S) group, significantly higher than that in HLAMKO group (12.7%) (P＜0.01).CONCLUSION: TB patients with HBV should choose HLAMKO treatment because of fewer hepatotoxicity.展开更多

Patient＇s characteristics, laboratory investigations, radiological, endoscopic and surgical findings were evaluated. Abdominal site involved （intestinal, peritoneal, visceral, and nodal） and response to treatment was also noted.RESULTS： There were 209 patients enrolled. One hundred and twenty-three （59%） were females. Symptoms were abdominal pain 294 （93%）, fever 234 （64%）, night sweats 99 （48%）, weight loss 98 （47%）, vomiting 75 （36%）, ascites 74 （35%）, constipation 64 （31%）, and diarrhea 25 （12%）. Sub-acute and acute intestinal obstruction was seen in 28 （13%） and 12 （11%） respectively. Radiological evidence of pulmonary tuberculosis was found in 134 （64%） patients. Basis of diagnosis of abdominal tuberculosis were radiology （Chest and barium X-Rays, Ultrasound and CT scan abdomen） in 111 （53%） and histo-pathology （tissue obtained during surgery, colonoscopy, CT or ultrasound guided biopsy, laparoscopy and upper gastro intestinal endoscopy） in 87 （42%） patients. Mycobacterium culture was positive in 6/87 （7%） patients and response to therapeutic trial of anti tubercular drugs was the basis of diagnosis in 5 （2.3%） patients. Predominant site of involvement by abdominal TB was intestinal in 103 （49%） patients, peritoneal in 87 （42%） patients, solid viscera in 10 （5%） and nodal in 9 （4%） patients. Response to medical treatment was found in 158 （76%） patients and additionally 35 （17%） patients also underwent surgery. In a 425 ± 120 d follow-up period 12 patients died （eight post operative） and no case of relapse was noted.CONCLUSION： Abdominal TB has diverse and nonspecific symptomatology. No single test is adequate for diagnosis of abdominal tuberculosis in all patients. Abdominal TB in non-HIV patients remains an ongoing diagnostic dilemma requiring a high index of clinical suspicion.展开更多

Endoscopic retrograde cholangiopancreatography （ERCP） confirmed dilatation of the intrahepatic bile ducts and also showed an irregular stricture of the common hepatic duct at the liver hilum. Histological examination of biopsies from the bile duct revealed epithelioid cell granulomas and caseous necrosis. Tubercle bacilli were then detected on polymerase chain reaction （PCR） testing of the bile, giving the diagnosis of biliary tuberculosis. Although microbiological cure was confirmed, the patient developed cicatricial stenosis of the hepatic duct. She underwent repeated treatments with endoscopic biliary drainage （EBD） tubes and percutaneous transhepatic biliary drainage （PTBD） tubes, and the stenosis was corrected after 6 years. We present a case of tuberculous biliary stricture, a condition that requires careful differentiation from the more common malignancies and needs long-term follow-up due to the risk of posttreatment cicatricial stenosis, although it is rare.展开更多

None had a history of peptic ulcer disease or had taken antibiotics, bismuth compounds and/or PPI in the previous month, 14C-UBT was repeated at the end of the second month and the end of treatment period and one month after completion of treatment course.RESULTS: Thirty-five patients (23 males) were enrolled.14C-UBT was negative in all 35 patients (100%) at the end of the second month and remained negative in 30cases (85.7%) at the end of the treatment course. One month after completion of treatment course, UBT remained negative in 13 patients (37.1%).CONCLUSION: Our report underscores the need for caution while interpreting urea breath test results in patients undergoing anti-TB therapy. Furthermore, the combination of drugs used in this study resulted in H pylori eradication in a minority of patients.展开更多

All patients had evidence of tuberculosis infection with a failure of anti-tuberculosis treatment for more than one year,and were subsequently diagnosed with CD. All the patients received thalidomide treatment with a starting dose of 1.2-2.5 mg/kg per day. Remission was defined as pediatric CD activity index less than or equal to 10.RESULTS Ten patients with CD were treated with thalidomide at an average age of 7.2 years and followed up for a median of 22.2 mo. Clinical remission rate was 60% after 9-12 mo of thalidomide treatment. One patient with no response had an interleukin-10 receptor alpha gene mutation. Erythrocyte sedimentation rate,C-reactive protein and platelet count showed a dramatic decrease; hemoglobin level and weight improved significantly after thalidomide treatment when compared with the baseline values.CONCLUSION Thalidomide is an effective and safe drug for remission of CD in pediatric patients who have been treated for tuberculosis.展开更多

To analyze ten cases of MGTT with pulmonary metastasis complicated with pulmonary tuberculosis in our hospital from 1980 to 1997 retrospectively. Results.From the x ray film, there are great resemblances between MGTT with pulmonary metastasis and pulmonary tuberculosis. Of 10 patients, 7 of them were examined out pulmonary tuberculosis during the chemotherapy of MGTT. Pulmonary tuberculosis appeared six months before chemotherapy in three cases. All of the patients were treated with multiagent chemotherapy. Seven patients achiceved a complete remission, 2 patients developed drug resistance and died of cerebral haemorrhage and cerebral herniation, 1 woman who had achieved a complete remission from MGTT for 14 months died of miliary tuberculosis. Conclusion. It is very important to make differential diagnosis of the MGTT with pulmonary metastasis complicated with pulmonary tuberculosis. Trying to avoid excessive anti tumor treatment owing to mistake pulmonary tuberculosis for pulmonary metastasis, and avoiding missing an opportunity of anti tuberculosis treatment because of missed diagnosis should be emphasized.展开更多

Obvious pulmonary involvement is exceptional. Tracheal involvement in Crohn's disease is even more unusual, only a few cases have been report-ed to date. We herein report a rare case of tracheobron-chial nodules and pulmonary infiltrates in both lungs as a complication of Crohn's disease. A 42-year-old man underwent pancolectomy for multiple broken colon caused by Crohn's disease. Forty days later pulmonary symptoms and radiologic abnormalities were noted. A search for bacterial (including mycobacteria) and fungal in the repeated sputum proved negative. The treatment consisted of intravenous antimicrobials for one month, but there was no improvement in pyrexia or cough and radiologic abnormalities. Fibreoptic bronchoscopy (FOB) was performed and revealed nodes in the trachea and the right upper lobe opening. Histopathology of tracheo-bronchial nodules and bronchial mucosa biopsy specimen both showed granulomatous inflammation with proliferation of capillaries and inflammatory cells. Oral steroid and salicylazosulfapyridine were commenced and led to marked improvement in symptoms and an almost complete resolution of his chest radiograph. Repeated FOB showed that nodes in the trachea disappeared and the ones in the right upper lobe opening diminished obviously. Crohn's disease can be associated with several respiratory manifestations. The form of tracheal and bronchopulmonary involvement in Crohn's disease is rare and responded well to steroids.展开更多

Isoniazid(IN), a low-molecular-weight hydrophilic drug, was used as a model drug. The effects of various sizes of micronized IN powder, different drug/polymer ratios, spray-drying process parameters, and drug-release characteristics were studied to optimize the manufacturing parameters. A high entrapment efficiency(87.3%) was obtained using this method; furthermore, the microspheres were spherical and smooth. They were individually and homogenously distributed, with a mean diameter of 5.6 μm; furthermore, they showed a satisfactory extended sustained-release phase. After administration of the microspheres to rats, pulmonary drug concentrations were maintained at a relatively stable level for up to 4 weeks.展开更多
