Changing pattern of visceral leishmaniasis, United Kingdom, 1985-2004.

A 20-year (1985-2004) retrospective review of 39 patients with imported visceral leishmaniasis found that tourism to Mediterranean countries and HIV infection were associated with visceral leishmaniasis. Diagnosis was often delayed. Treatment with liposomal amphotericin B has improved prognosis. Visceral leishmaniasis should be made a reportable disease

Leprosy and HIV, where are we at?

The impact of leprosy and HIV co-infection is an evolving picture. Surprisingly the outcomes that were feared, of more lepromatous disease has not materialised. But with the roll-out of antiretroviral therapy, the emergence of leprosy as Immune Reconstitution Inflammatory Syndrome is re-focusing attention on the characteristics of this important co-infection

The use of steroids and thalidomide in the management of Erythema Nodosumn Leprosum; 17 years at the Hospital for Tropical Diseases, London

Objectives: Prednisolone and thalidomide are commonly used in the management of erythema nodosum leprosum (ENL) and bring relief to patients with this condition worldwide. However, both ENL and its treatments can cause significant morbidity. This study describes the spectrum of ENL seen at The Hospital for Tropical Diseases, London (HTD), the use of steroids and thalidomide in its management and the complications of their use. Study Design: We conducted a retrospective audit of patients diagnosed with ENL between 1996 and 2013. Data were obtained from hospital records including severity and length of disease, together with treatments received and adverse effects. Results: Between 1996 and 2013, 30 patients were diagnosed with ENL. The median bacillary index (BI) at diagnosis was 4·65, higher than in previous studies. Most patients developed ENL during leprosy treatment (67%) and had chronic ENL (57%). The median length of ENL was 60 months (range 9 – 192); patients with BI . 4·5 had significantly longer duration of disease. 87% patients received prednisolone for median nine months; 35% developed adverse effects including diabetes and hypertension. 87% patients received thalidomide for median 16 months; 65% complained of side effects. There were no pregnancies or venous thromboembolisms. 77% patients stopped prednisolone within two months of starting thalidomide. There were no deaths in our cohort. Conclusion: We describe the clinical course of ENL in a non-endemic country with access to thalidomide and prednisolone. ENL may last far longer than previously described and has significant impact on a patient’s health. In the UK, thalidomide is essential as a steroid-sparing agent, to prevent the adverse effects and mortality of long-term steroids which have been documented elsewhere.</p

Visceral Leishmaniasis in Traveler to Guyana Caused by Leishmania siamensis, London, UK.

The parasite Leishmania siamensis is a zoonotic agent of leishmaniasis; infection in animals has been documented in Europe and the United States. Reported authochthonous human infections have been limited to Thailand. We report a case of human visceral Leishmania siamensis infection acquired in Guyana, suggesting colonization in South America

The mortality associated with erythema nodosum leprosum in Ethiopia: a retrospective hospital-based study.

BACKGROUND: Erythema nodosum leprosum (ENL) is a debilitating multisystem disorder which complicates leprosy. It is characterised by fever, malaise and painful erythematous cutaneous nodules. ENL is often recurrent or chronic in nature and frequently severe. Patients often require prolonged treatment with high doses of oral corticosteroids. There are no data on the mortality associated with treated ENL. METHODOLOGY: The notes of patients who were admitted, discharged, transferred to another facility or died with a diagnosis of leprosy or a leprosy-related complication for a five year period were reviewed. RESULT/DISCUSSION: 414 individuals were identified from the ward database. 312 (75.4%) patient records were located and reviewed. Ninety-nine individuals had ENL and 145 had a Type 1 reaction. The median age of individuals with ENLwas 25 years. Eight patients with erythema nodosum leprosum died compared with two diagnosed with Type 1 reaction. This difference is statistically significant (p = 0.0168, Fisher's Exact Test). There is a significant mortality and morbidity associated with ENL in this Ethiopian cohort. The adverse outcomes seen are largely attributable to the chronic administration of oral corticosteroids used to control the inflammatory and debilitating symptoms of the condition
