A 50-year-old Sinhalese man with poorly controlled diabetes mellitus presented with facial infiltration (Fig. ) and erythematous painful nodules over his lower limbs and trunk suggestive of lepromatous leprosy with erythema nodosum leprosum. He was a manual laborer with low BMI. The rest of the general and neurological examination was normal. He had received a BCG vaccination. He did not smoke tobacco and drank alcohol occasionally. A skin biopsy revealed evidence of foamy macrophages with well-developed grenz zone. He was commenced on multidrug treatment-multibacillary treatment for leprosy (dapsone 100 mg/day, clofazimine 50 mg/day and 300 mg/once a month, and rifampicin 600 mg/month) with prednisolone 40 mg daily for type 2 reaction. Twelve months later he developed generalized lymphadenopathy with low-grade evening pyrexia and elevated ESR (80–100 mm/hour). Both Mantoux and QuantiFERON Gold test were positive. A CXR remained persistently normal. He was negative for HIV and diabetes. Basic investigations are given in Table . A lymph node excision biopsy revealed suppurative inflammation with focal foamy histiocytes; a TB culture from the lymph node biopsy later showed growth of AFB. GeneXpert did not reveal rifampicin resistance. Therefore, he was started on TB treatment (isoniazid 300 mg/day, rifampicin 450 mg/day, ethambutol 800 mg/day, and pyrazinamide 1500 mg/day) by the respiratory physician for the treatment of extrapulmonary TB. At 6 months, he had improved clinically and biochemically.
A 25-year-old man was admitted with complaints of fever, which was mainly in the evening, of nearly 1-week duration associated with cough, breathlessness, and generalized fatigue. He was on standard multidrug therapy (Rifampicin, Clofazamine, Dapsone) for lepromatous leprosy, for the last 2 years, but he was not very compliant with drug intake. He developed ENL for which he was started on steroids for the last 6 months. He did not have any addictions.\nOn examination he was sick looking, and had severe pallor, generalized lymph node enlargement, diffuse erythematous lesions, and nodular tender lesions of varying size all over the body. The scalp and oral mucosa were not involved. At the time of admission his temperature was 40°C, blood pressure was 120/70 mm of Hg and pulse rate was 114/m and respiratory rate was 38/m. Respiratory system examination revealed bilateral scattered crepitations and rhonchi. He had a hepatomegaly of 5 cm below the costal margin in the right midclavicular line and splenomegaly of 3 cm.\nInvestigations revealed Hb 6 g%, total leucocyte count 1000/mm3 (P 85%, L 15%), ESR 130 mm in the first hour, platelet count 3.2 lakhs/mm3, renal and liver function tests within normal limits, MCV 80, MCH 24, MCHC 30, reticulocyte count 3.5%. Peripheral smear showed normocytic normochromic cells with no evidence of hemolysis; WBCs were increased in number with predominance of neutrophils; and platelets were adequate. CRP was 160 mg/l, and slit-skin smear from the ear lobe was tested positive for lepra bacilli, BI 6%, MI 0%. X-ray chest was normal, sputum was positive for AFB, and HIV status was negative.\nWith the clinical scenario and investigation results the diagnosis of Hansen's disease, ENL, pulmonary tuberculosis, SIRS was made. He went into hypotension which was corrected with fluid replacement. Spo2 was maintained at 98%, without supplemental o2. He was started on broad spectrum antibiotics and DOTS CAT I ATT. The treatment for leprosy was continued. Fever subsided in 3 days and he was discharged.
