RESUMO
Chronic disseminated candidiasis (CDC) is a severe complication of a disseminated yeast infection mainly seen after prolonged chemotherapy-induced neutropaenia in the context of haematological malignancy. We present a case of CDC in a patient with metamizole-induced neutropaenia. To the best of our knowledge, this is the first case described in this context. Furthermore, we highlight the role of steroids in the management of this disease.

OBJECTIVE: To determine changes of cerebrospinal fluid (CSF) biomarkers of patients on monotherapy with lopinavir/ritonavir. DESIGN: The Monotherapy Switzerland/Thailand study (MOST) trial compared monotherapy with ritonavir-boosted lopinavir with continued therapy. The trial was prematurely stopped due to virological failure in six patients on monotherapy. It, thus, offers a unique opportunity to assess brain markers in the early stage of HIV virological escape. METHODS: : Sixty-five CSF samples (34 on continued therapy and 31 on monotherapy) from 49 HIV-positive patients enrolled in MOST. Using enzyme-linked immunosorbent assay, we determined the CSF concentration of S100B (astrocytosis), neopterin (inflammation), total Tau (tTau), phosphorylated Tau (pTau), and amyloid-ß 1-42 (Aß), the latter three indicating neuronal damage. Controls were CSF samples of 29 HIV-negative patients with Alzheimer dementia. RESULTS: In the CSF of monotherapy, concentrations of S100B and neopterin were significantly higher than in continued therapy (Pâ=â0.006 and Pâ=â0.013, respectively) and Alzheimer dementia patients (Pâ<â0.0001 and Pâ=â0.0005, respectively). In Alzheimer dementia, concentration of Aß was lower than in monotherapy (Pâ=â0.005) and continued therapy (Pâ=â0.016) and concentrations of tTau were higher than in monotherapy (Pâ=â0.019) and continued therapy (Pâ=â0.001). There was no difference in pTau among the three groups. After removal of the 16 CSF with detectable viral load in the blood and/or CSF, only S100B remained significantly higher in monotherapy than in the two other groups. CONCLUSION: Despite full viral load-suppression in blood and CSF, antiretroviral monotherapy with lopinavir/ritonavir can raise CSF levels of S100B, suggesting astrocytic damage.
