Atypical cutaneous leishmaniasis in two patients receiving low-dose methotrexate

BRITISH JOURNAL OF DERMATOLOGY, Issue 4 2006
M. Saha
Summary Cutaneous leishmaniasis is a protozoan disease that has high morbidity. There have been increasing reports of leishmaniasis in patients with an underlying immunosuppressed state. We present two cases of cutaneous leishmaniasis caused by Old World species in patients on methotrexate therapy. We postulate that the T-cell-mediated response to leishmaniasis infection could be modulated by methotrexate and may render an immunosuppressed individual more susceptible to developing clinical disease.

Visceral Leishmaniasis in a Kidney Transplant Recipient: Parasitic Interstitial Nephritis, a Cause of Renal Dysfunction

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2010
S. Dettwiler
Visceral leishmaniasis (VL) due to Leishmania infantum is an endemic parasitic infection in the Mediterranean area. It most commonly affects immunosuppressed individuals, especially HIV patients and less frequently organ transplant recipients. Renal involvement seems to be frequent and is mostly associated with tubulointerstitial nephritis, as described in autopsy reports. In the 61 cases of renal transplant recipients with VL reported in the literature, renal dysfunction was noted at clinical presentation and was more frequently observed as a complication of antiparasitic therapy. However, no pathological analysis of the allograft lesions was reported. We present the case of a Swiss renal transplant recipient who developed VL after vacations in Spain and Tunisia, complicated by acute parasitic nephritis in the renal allograft 3 months after a well-conducted treatment of liposomal amphotericin B.

Strongyloides stercoralis hyperinfection: difficulties in diagnosis and treatment

ANAESTHESIA, Issue 3 2010
N. M. Feely
Summary Immunocompromised patients who are infected with Strongyloides stercoralis may develop a potentially fatal auto-infection syndrome characterised by non-specific pulmonary and gastrointestinal symptoms and Gram negative sepsis. We present the case of one such patient who underwent a negative laparotomy for a presumed intra-abdominal surgical catastrophe with a subsequent protracted stay on the intensive care unit. Once the diagnosis of strongyloidiasis was made, the patient was successfully treated with subcutaneous antihelminthic drugs. With appropriate screening for and eradication of strongyloides in those with immune compromise, or in those about to start immunosuppressive therapy, potentially fatal episodes of hyperinfection could be avoided. In the absence of screening, severe strongyloidiasis should be suspected in immunosuppressed individuals who have travelled to or resided in an endemic area and present with the characteristic features. Awareness of the signs of hyperinfection amongst those involved in acute care could prevent unnecessary morbidity and mortality in these patients. [source]

Kaposi's sarcoma-like lesions and other nodules as cutaneous involvement in AIDS-related visceral leishmaniasis

BRITISH JOURNAL OF DERMATOLOGY, Issue 6 2000
M.J. González-Beato
A 40-year-old human immunodeficiency virus (HIV)-positive man had three relapses of visceral leishmaniasis (VL). In the third he developed nodular skin lesions of three types, some reminiscent of Kaposi's sarcoma. Biopsy of each type disclosed abundant dermal macrophages with a huge number of intracellular and extracellular Leishman,Donovan bodies. Rapid improvement of lesions was achieved after antiparasitic treatment. AIDS leads to atypical forms of leishmaniasis. Leishmania has been detected both in normal and pathological skin of these patients due to dissemination during VL. It is suspected that a considerable proportion of the population may be infected in endemic areas, Leishmania being opportunistic in immunosuppressed individuals. It is important to recognize the range of lesions that may occur in patients with HIV and VL, many of which are non-specific and may cause diagnostic difficulty. [source]
