Abstract:
A case of visceral leishmaniasis (VL) in a 77-year-old woman, with renal failure on haemodialysis, admitted in the intensive care unit (ICU) with vascular instability requiring vassopressor treatment, is presented. Initially, no co-infection could be detected. The patient initially responded well when liposomal amphotericin B was administered, after bone marrow demonstrated multiple intra-cellular Leishmania amastigotes and extra-cellular promastigotes. However, the patient died from uncontrolled septic shock from a secondary bacterial infection, the tenth day of admission. To our knowledge, vascular instability has not been reported in VL. Moreover, non-vector transmission was also suspected in this case. The patient had undergone cholecystectomy three months earlier, during which two blood units had been transfused; IgG anti-Leishmania antibodies at a high titer were detected in one of the two healthy blood donors, later.

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
