A 50-year-old non-diabetic, non-hypertensive man who had completed treatment for lepromatous leprosy two years back, was admitted at Green Pastures Hospital for type-2 lepra reaction (erythema nodosum leprosum). There was a past history of lepra reactions for which he underwent treatment. Currently the patient was again being treated for the same with prednisolone 30 mg once daily, thalidomide 100 mg twice daily and clofazimine 50 mg once daily. However, information about initial screening of tuberculosis was not available.\nThe patient was referred to our teaching hospital with complaints of fever, productive cough and dyspnoea of three months duration. The patient also complained of pain and distension of abdomen and decreased appetite for three months.\nClinical examination revealed tense abdomen with shifting dullness, respiratory system with bilateral crackles with bronchial breath sounds predominantly in the left infra clavicular area, and skin showed no active lesions of erythema nodosum leprosum. The laboratory investigations revealed hemoglobin: 11.8 mg/dl; total leukocyte count: 5900/mm3; erythrocyte sedimentation rate: 110 mm in first hour; random blood sugar: 109 mg/dl; serum electrolytes, sodium: 135 meq/L and potassium: 3.2 meq/L.\nTwo out of three sputum samples were positive for acid fast bacilli. Chest radiograph showed multiple heterogeneous opacities in bilateral lung fields and a cavitary lesion in left upper zone. A diagnosis of pulmonary tuberculosis and provisional diagnosis of peritoneal tuberculosis were made.\nDermatologist's opinion was sought for the lepra reaction. The patient was advised to stop prednisolone as no active lesions persisted. He was subsequently referred to DOTS clinic and was started on category-I treatment.
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.
