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 49-year-old man, nonsmoker, was admitted to dermatology department and followed up for diffuse lepromatous leprosy. He was vaccinated with BCG and he had no past history of tuberculosis. Diagnosis of leprosy was documented based on histological and bacteriologic evidence: a slit skin smear from the ear lobe was positive for lepra bacilli (BI3+), histopathology from the lesion on the face showed granulomas consisting of epithelioid histiocytes and lymphocytes with central caseous surrounding vessels and nerves, and PCR of biopsy specimens were positive for Mycobacterium leprae. After successful treatment using dapsone (100 mg/day), rifampicin (600 mg/month), and clofazimine (300 mg/month and 50 mg/day) during twelve months, hypopigmented skin lesions on the trunk and congestive rhinitis disappeared and the slit skin smear was negative. One month after the end of the treatment, he presented with diffuse papulonodular lesions on the face and trunk, fever, and alteration of general status. On the basis of his symptoms, diagnosis of leprosy reaction (type II) was made and the patient was treated using prednisone at a dose of 40 mg/kg/day. Outcome was unfavorable after two months of corticotherapy, and we had to wait for two supplementary months before we could get clofazimine to add corticoid. After 1 month of this treatment, he presented with fever, weight loss, and asthenia. Clinical examination revealed fever of 39°C, nodular lesions over face, trunk, forearms, and dorsum of hands (Figures , , and ). He presented no neurologic impairment. Biological examination showed inflammatory syndrome: CRP 393 mg/L, total leukocyte count 16,2 × 109/L, neutrophilia 15,3 × 109/L, and lymphopenia 0,48 × 109/L. Serum creatinine and alanine aminotransferase were normal. HIV status was negative. Two out of three sputum samples were positive for acid fast bacilli. Chest tomography showed alveolar-interstitial opacities at the left lower lobe (). Bronchoscopy detected thickening of lower lobar bronchi, without malignancy in histopathology of biopsy specimens. The patient was treated by antitubercular treatment. One month after the onset of this treatment, there were only two nodular lesions on the trunk, fever disappeared, and general status improved.
