A 15-year-old female was admitted to our department with the complaints of breathlessness, and off and on fever for 1 month. She came from a nonendemic zone of filariasis in Uttar Pradesh. The resting pulse rate was 92/min and blood pressure was 112/74 mmHg. There was no history of contact with a tuberculosis patient. Her physical examination revealed hard, mobile lymph nodes of size 2 × 2 cm approximately, present bilaterally in the cervical region, and pallor. On chest examination, there was stony dull note localized to the bilateral infrascapular, lower axilla. Rest of the systems were within normal limits.\nHer blood examination revealed anemia, and hypoalbuminemia but normal total and differential leukocyte counts. Her chest x-ray revealed bilateral pleural effusion []. The pleural fluid was aspirated (about 2.0 l from left and 1.2 l from right) on both sides that revealed a milky white fluid. Then we thought about the chylothorax. Clearing of the pleural fluid by adding ethyl-ether into it leads to the exclusion of pseudochylothorax. The pleural fluid of both sides was sent for examination that revealed, for the right side, protein 4.2 g%, sugar 44 mg%, and total leukocyte count 3400 cells/mm3; differential leukocyte count was neutrophils 20, lymphocytes 80, pleural fluid triglyceride 535 mg%, and pleural fluid cholesterol 24.8 mg%; pleural fluid of the left side revealed protein 4.0 g%, sugar 40 mg%, and total leukocyte count 3280 cells/mm3; differential leukocyte count was neutrophils 34, lymphocytes 66, pleural fluid triglyceride 188.0 mg%, and pleural fluid cholesterol 24.0 mg% []. Serum triglyceride and serum cholesterol was 72.7 mg% and 71.9 mg%, respectively. The Ziehl-Neelsen stain of the pleural fluid was negative but Mycobacterium tuberculosis was isolated on the Lowenstein–Jensen culture. The pleural fluid culture for pyogenic organisms was sterile in nature on both sides. PPD showed no indurations. Her biopsy of the cervical lymph node revealed caseating granuloma, and the Bactec culture for M. tuberculosis was also positive in the cervical lymph node biopsy specimen. Her abdomen ultrasound also revealed multiple retroperitoneal and para-aortic lymphadenopathy. Thus a diagnosis of bilateral chylothorax secondary to tuberculosis with cervical lymphadenopathy was established.\nTo confirm the exact site of the thoracic duct tear, lymphangiography was planned but her parents refused for further investigations.\nShe was put on standard 6-month antitubercular treatment: a combination of isoniazid, rifampicin, pyrazinamide, and ethambutol was started for 2 months followed by isoniazid and rifampicin for a further 4 months. Following this, she showed clinical as well as radiological improvement and chylothorax resolved after 2 months of treatment [], and on regular follow-up she had no further symptoms.
A 33-year-old man, diagnosed case of chronic kidney disease secondary to diabetes mellitus on maintenance dialysis presented to pulmonary medicine outpatient unit with complaints of intermittent fever and weight loss of 2 months duration. On examination, he was febrile (38.4 Celsius) with a respiratory rate of 20/min, pulse rate of 104/min, blood pressure of 140/90 mmHg, and oxygen saturation of 96% on room air. General examination revealed pallor and bilateral pitting pedal edema. His respiratory-, cardiac-, abdominal- and neurological examination was within normal limits. Laboratory examination showed hemoglobin of 7.2 g/dL (normal 11.5–16.5), platelet count of 22 × 109/L (normal 150–500), white cell count of 3.2 × 109/L (normal 4.3–10.8) with neutrophils 65%, lymphocyte 32%, and monocyte of 3%. His glycated hemoglobin was 5.6% (normal <6.5%) and liver function test revealed albumin of 2.2 g/dL (normal 3.5–5 g/dL). Rest of the biochemical investigations were within normal limits. HIV serology was negative. Even though, the patient had normal blood picture and reticulocyte count, bone marrow study was done for his leukopenia.\nChest X-ray posteroanterior (PA) view revealed increased bronchovascular markings [] and computed tomography (CT) thorax with abdomen [] showed bilateral mild pleural effusion with significant mediastinal and abdominal adenopathy. Ultrasound chest was done and it revealed minimal pleural effusion and the same was not tappable. CT-guided fine-needle aspiration was done from paraaortic lymph nodes. Histopathology from bone marrow and cytology of paraaortic lymph nodes showed caseous necrotic granulomatous inflammation suggestive of TB. Acid-fast culture of bone marrow tissue and lymph node aspirate revealed growth of pansensitive mycobacterium TB. He was initiated on modified antitubercular treatment for his kidney disease and the regimen included rifampicin 450 mg daily, isoniazid 300 mg daily, ethambutol 800 mg thrice weekly, and pyrazinamide 1250 mg thrice weekly.\nSix weeks postantitubercular treatment, he came to our casualty with complaints of fever and exertional breathlessness. Patient was febrile (38.6°C) with respiratory rate of 32/min, pulse rate of 120/mine, blood pressure of 150/92 mm of Hg, and oxygen saturation of 92% at room air. Respiratory examination was suggestive of right pleural effusion. Rest of the examination was within normal limits. Chest X-ray PA view showed features suggestive of right moderate to massive pleural effusion []. Diagnostic thoracocentesis revealed milky white fluid and analysis showed total protein 4.1 g/dL, glucose 117 mg/dL, total cholesterol 68 mg/dL, triglycerides 751 mg/dL, and chylomicrons 1050 mg/dL. Cytology of the pleural fluid was negative for malignant cells, cultures for bacteria and mycobacteria were negative. Hence, a diagnosis of chylothorax was made. Repeat CT thorax with abdomen showed an increase in the size of mediastinal and abdominal lymphadenopathy. Hence, the acute worsening in patient clinical condition was attributed to be part of PR/IRIS, developing secondary to antitubercular treatment. His antitubercular therapy was continued and was managed symptomatically with parenteral nutrition, therapeutic thoracocentesis, antipyretics, and oxygen; nonsteroidal anti-inflammatory drugs were deferred in view of renal disease. Despite these he was symptomatic, so initiated on tab prednisolone 1 mg/kg/day. In view of persisting breathing difficulty, increasing oxygen requirement and worsening pleural effusion radiologically after informed consent intercostal drain (ICD) was inserted. Post-ICD X-ray showed partial expansion of lung, so patient was connected to −20 cm water suction. Despite these lung failed to expand, thoracic surgery opinion was obtained and he underwent decortication and interruption of the thoracic duct. Histopathology of the operated specimen showed fibrous connective tissue, fibrinous, and acute inflammatory exudates. Postoperative chest X-ray showed good lung expansion and resolution of right pleural effusion []. Prednisolone 1 mg/kg daily was continued for 2 weeks, then, it was tapered to 0.5 mg/kg and the same was given for 2 more weeks. The patient was discharged on antitubercular treatment and was advised to continue the same for total of 6 months. On follow-up, patient showed good clinical recovery.
