A 65-year-old non-hypertensive, non-diabetic man presented with history of left sided chest pain associated with productive cough and breathlessness for seven days. There was no history of fever, haemoptysis and exertional increase in breathlessness. The patient was referred to our teaching hospital from Green Pastures Hospital (GPH), a tertiary care referral centre for leprosy. The patient was treated for leprosy with WHO multidrug therapy for multibacillary leprosy. The patient was currently on treatment for ulnar neuritis with prednisolone 30 mg once a day for last three months. There was no past history of tuberculosis as per GPH records or information provided by the patient.\nClinical examination revealed numerous hypopigmented skin lesions varying in size from 2 to 10 centimeters over the trunk. The left ulnar nerve was thickened. There was dullness and decreased breath sounds in the left infrascapular and axillary areas.\nThe laboratory investigations revealed hemoglobin: 14.4 mg/dl; total leukocyte count: 19.5×103; erythrocyte sedimentation rate: 60 mm at the end of first hour; serum creatinine: 1.4 mg/dl; and random blood sugar: 91 mg/dl.\nOne out of three sputum samples tested was positive for acid fast bacilli and the chest radiograph showed loculated pleural effusion suggesting long standing pleural collection in left hemi thorax with infiltrations bilaterally, more on left side.\nA diagnosis of borderline leprosy with concomitant pulmonary tuberculosis was made. The patient was referred to DOTS clinic of our teaching hospital and started on category-I treatment according to the guidelines of national tuberculosis programme of Nepal. The oral prednisolone was subsequently tapered and stopped. The patient's general condition improved and was on regular follow up.
A 47-year-old Tamil woman with poorly controlled long-standing diabetes mellitus presented with facial infiltration, multiple ichthyotic patches, and peripheral neuropathy associated with Charcot joints and trophic ulcers (Fig. ). She was a homemaker with poor social background and there was no contact history of TB or leprosy. She did not smoke tobacco or drink alcohol. She had received a BCG vaccination. She had a low BMI and a respiratory examination revealed B/L coarse crepitations. There was no peripheral neuropathy. A clinical diagnosis of lepromatous leprosy was made which was later confirmed with histology and slit-skin smears: bacteriological index (BI) of 5; morphological index (MI) of 2%. Initial investigations revealed persistently elevated ESR (100–122 mm/hour) and inflammatory shadows in a CXR. Two consecutive sputum smears were positive for AFB and the result of a Mantoux test was positive (18 mm). Her liver and renal functions were normal (Table ). She was negative for HIV screening. She was commenced on both TB (isoniazid 300 mg/day, rifampicin 450 mg/day, ethambutol 800 mg/day, and pyrazinamide 1500 mg/day) and multibacillary leprosy treatment (dapsone 100 mg/day and clofazimine 50 mg/day and 300 mg/once a month) without a monthly loading dose of rifampicin. She had poor compliance and defaulted treatment several times and ultimately succumbed to the illness. An autopsy was not performed.
