Primary peritoneal tuberculosis is a rare presentation of this disease. It is usually associated with ascites and raised CA-125 levels. Occasionally a pelvic mass may be present making the preoperative differential diagnosis from advanced ovarian cancer extremely difficult. Acid-fast stains and special cultures of the ascitic fluid for Mycobacterium tuberculosis are frequently negative, and confirmation of the diagnosis commonly requires histologic examination of biopsy specimens, in which epithelioid granulomas with central caseous necrosis can be identified. We present a case of unexplained pyrexial ascites in a postmenopausal woman in whom the diagnosis of miliary peritoneal tuberculosis was confirmed laparoscopically. The role of noninvasive tools such as measurement of ascitic fluid adenosine deaminase levels is also discussed.

In an attempt to differentiate between three important but clinically similar conditions of exudative ascites like tuberculous peritonitis, spontaneous bacterial peritonitis (SBP) and malignant ascites, we evaluated the biochemical parameters of ascitic fluid as a diagnostic aid. The serum ascitic albumin gradient (SAAG), lactate dehydrogenase (LDH), pH, adenosine deaminase(ADA), carcino-embryonic antigen (CEA) and carbohydrate antigen (CA-125) levels were measured in 36 patients with tuberculous peritonitis, 30 patients with SBP and 30 patients with ascites due to malignant disorders. The LDH level was significantly lower in tuberculous peritonitis patients than in malignant and SBP groups. A value of < 110 U/l gave the assay a sensitivity of 94% and a specificity of 93%, positive predictive value of 89% and negative predictive value of 96% for tuberculous peritonitis. The ADA activity was significantly higher in tuberculous peritonitis group than in the other two groups. A cut off value > 33 U/l gave the ADA test a sensitivity of 89%, specificity of 100%, positive predictive value of 100 % and a negative predictive value of 94% for tuberculosis. A pH value of <7.26 with high SAAG (>11 g/l) predicted SBP with reasonable accuracy. Elevated ascitic fluid CEA (>2 ng/ml) and CA - 125(> 35 U/l) was found exclusively in cases of malignant ascites with a single case of tuberculous peritonitis showing CA-125 value > 35 U/l. All these tests are rapid, non-invasive, and easily reproducible and offer good predictive accuracy which is comparable to that of more invasive procedures like peritoneoscopy and biopsy.

A hemodialysis patient with tuberculous peritonitis with hypercalcemia and high serum soluble interleukin-2 receptor (sIL-2R) and CA-125 levels is reported. An 82-year-old woman who had been on hemodialysis therapy for 6 years was admitted to our hospital for evaluation and treatment of hypercalcemia. Laboratory examination and radiologic studies revealed markedly increased serum sIL-2R and CA-125 levels and exudative ascites, with high levels of adenosine deaminase (ADA) and CA-125, which was suggestive of malignancy or tuberculosis. She was finally diagnosed as having tuberculous peritonitis based on positivity for Mycobacterium tuberculosis in ascitic fluid. The ascites subsided with normalization of hypercalcemia and a marked decrease in serum sIL-2R and CA-125 levels in response to anti-tuberculosis treatment. This case indicates that serum sIL-2R and CA-125 levels can rise to levels suggestive of malignancy in tuberculous peritonitis, and that they can be used to monitor the response to anti-tuberculosis treatment.

Pleural effusion (PE) is a very uncommon manifestation of sarcoidosis. It is equally observed in men and women, can appear at any age and in all radiologic stages, though it is more common in stages i and ii. Effusions have usually a mild or medium size and mainly involve the right side. Various mechanisms can be implicated. PE will be a serous exudate if there is an increase in the capillary permeability due to direct involvement of the pleural membrane, a chylothorax if mediastinum lymph nodes compress the thoracic duct and/or the lymphatic drainage from the pleural cavity, an hemothorax if granuloma compress or invade pleural small vessels or capillaries, and even a transudate if there is compression of the inferior vena cava, atelectasis due to complete bronchial obstruction or when the resolution of the PE is incomplete with chronic thickening of visceral pleura (trapped lung). It manifests biochemically as a pauci-cellular exudate with a predominance of lymphocytes, though there can be a preponderance of eosinophils or neutrophils. Protein concentrations are usually proportionately higher than lactate dehidrogenase, adenosine deaminase is normally low and it is possible to find increased levels of CA-125 in women. The tuberculin test is negative and pleural or lung biopsies yield the diagnosis by confirming the presence of non-caseating granulomata. These PE can have a favorable self-limited outcome, even though in most cases treatment with corticosteroids is needed, while surgery is required in a few cases.
