Infection disease due to Listeria monocytogenes, which is a ubiquitous positive Gram bacillus to the essentially alimentary transmission, listeriosis happens on patients presenting an immunodeficiency. The authors report the two first cases of listeriosis diagnosed at Hopital Principal de Dakar. The first case was observed on a 73 years old man, hospitalised for a feverish coma scored at 9 using Glasgow scale, with neither meningitis syndrome, nor sign of neurological localisation. The analysis of the RLC reveals a hypercytosis at 126 GB/mm3, with prevailing neutrophile polynuclears, a hyperproteinorachia at 3.2 g/l. The culture of the RLC was sterile but the blood culture showed the presence of L. monocytogenes. The other paraclinical tests has revealed a glycaemia at 2.45 g/l, an imporant hepatic cytolisis with ASAT at 13 N and ALAT at 20 N. The patient was also presenting a cerebromeningitis and hepatic listeriosis on a diabetic field. The second case was observed on a 58 years old patient admitted for headaches, fever and an important degradation of the general state with an emaciation of 17 kg in 5 months. The physical screening revealed a bad general state, a fever at 38 degrees 2 and was without other particularity. The analysis of the RLC showed a hyperproteinorachia at 1.35 g/l with neither hypercytosis nor germ at the culture. Haemoculture isolated Listeria monocytogenes. HIV serology was positive. CD4 were counted to 61/mm3. and the viral charge was at 110.000 copies / mm3. The patient was presenting a Listeria monocytogenes at meningo-encephalitis on HIV-1 field. stade B of the CDC classification. This ubiquitous anthropozoonosis should be searched through early haemocultures before antibiotherapy. in case of long lasting fever, endocarditis, meningo-encephalitis, localised infections on children. pregnant women, diabetic persons, and people infected with HIV and some others presenting immunity troubles.

Reversible leukoencephalopathy syndrome (RLS) is a rare brain disorder, characterized by diffuse attenuation of cerebral white matter, which has been most commonly observed in transplant patients receiving calcineurin inhibitors or in patients with severe hypertension. We report an episode of RLS in a 22-year-old male patient on chronic hemodialysis with well-controlled moderate hypertension who presented with de novo headache and generalized seizures. Cranial magnetic resonance image (MRI) revealed multiple areas of increased signal intensity in the white matter on T2-weighed images which resolved spontaneously at subsequent MRIs. White blood cell count showed leucopenia with normal CD4 count at flow cytometry. A viral etiology could not be demonstrated. Reversible leukoencephaolopathy syndrome symptoms remitted within 72 h but leukopenia persisted over 10 months. The patient received a kidney transplant 15 months after RLS onset and has received cyclosporine since the second post-transplant day. No recurrence of RLS symptoms has been observed. The etiology of the MRI changes in the present case seemed not to be either vasogenic or cytotoxic.

A 28-year-old white man presented to the Emergency Department with a 24-hour history of an eruption on his extremities, trunk, and face. The patient was known to be HIV positive with a CD4 count of 527 and a viral load of 20,300. He denied fever, chills, malaise, and headache. His social history was significant for the fact that he was in a monogamous homosexual relationship. He had no recent travel, pet exposures, or sick contacts. Physical examination revealed stable vital signs and no documented fever. A maculopapular eruption was present on his face, trunk, and extremities (Figures 1 and 2). There was no palmar or plantar involvement. He was treated with diphenhydramine and topical 2.5% hydrocortisone and advised to return if his condition did not improve. Twelve days after the initial evaluation, the patient consulted us again due to progression of his dermatitis. He had no additional complaints other than an eruption on both palms but neither sole. (Figure 3). The eruption now demonstrated erythematous pink-red oval macules and papules 1-2 cm in size distributed on his scalp, face, trunk, and arms. A few papules contained fine collarettes of scale. Further questioning revealed that the patient had experienced a tender rectal ulcer 2 months previously. A punch biopsy and rapid plasma reagin were performed. The histopathologic examination revealed interface dermatitis with lymphocytes, plasma cells, occasional neutrophils, and a prominent lymphoplasmacytic perivascular dermatitis with infiltration of the vessel walls. Warthrin-Starry and Steiner methods demonstrated spirochetes at the dermal-epidermal junction and in vessel walls, consistent with Treponema pallidum (Figure 4). Rapid plasma reagin and fluorescent Treponema antibody were both reactive with a Venereal Disease Research Laboratory (VDRL) of 1:16. The patient was diagnosed as having secondary syphilis and treated with 2.4 million units of IM benzathine penicillin for 3 weeks. His eruption resolved after the initial treatment and he did not experience a Jarisch-Herxheimer reaction.

Treating Hepatitis C among HIV patients under antiretroviral drug therapy requires a high degree of vigilance and continuous monitoring because of frequent problems with intolerance and/or drug interactions. Recent studies, including three therapeutic trials, on Ribavic, APRICOT, and ACTG A5671, have given some insights on following these patients up. The adverse effects are relatively similar in HCV-HIV-co-infected patients and patients infected by HCV only. Their frequency is, on the other hand, higher among HCV-HIV-Co-infected patients. The adverse-effects are consistent, in a non-exhaustive way, with pseudo influenza-like symptoms, fever, myalgia, cephalgia, with psychiatric disorders (irritability, depression, etc.); endocrine disorders (thyroid dysfunction, diabetes...); and with hematological anomalies especially anemia and leucopenia. But the percentage of lymphocyte T CD4 is not modified, therefore there is no risk of opportunistic infection. Pharmacokinetic interactions between antiretroviral drugs and treatment for HCV infection including ribavirin plus interferon alpha (IFN-alpha) or pegylated IFN are described. They are almost exclusively due to the combination of ribavirin and of nucleoside analogue reverse transcriptase inhibitors. One of the principal consequences is the emergence of mitochondrial toxicity defined by the occurrence of hyperlactatemia, or acute pancreatitis). Thus, some combinations should be avoided such as ddI+ribavirin and ddI+d4T+ribavirin. The d4T+ribavirin combination must also be used with caution.

Alefacept is a selective immunomodulating, antipsoriatic drug that blocks the LFA-3/CD2 interaction necessary for the activation and proliferation of memory effector T cells by binding to CD2 expressed on the T cell surface. Because the CD4+ count is reduced by alefacept, it is recommended that this count be monitored on a regular basis to ensure that it does not drop below 250 cells/mul. Few side effects have been related to the use of alefacept that differ from placebo even when CD4+ counts drop below 250 cells/microl. The side effects that have been reported are minor and include: headache, nasopharyngitis, rhinitis, influenza, upper respiratory tract infections, pruritus, arthralgias, fatigue, nausea, accidental injury and increases in liver enzymes. Serious infections and malignancies do not appear linked to the use of alefacept. The percentage of patients who developed antibodies against alefacept is very low. Alefacept is a very safe biological therapy for moderate-to-severe chronic plaque psoriasis with few side effects reported. The utility of checking CD4 counts while administering alefacept for 12 weeks appears minimal.

Traditional Chinese medicine (TCM) has been used for prevention and treatment of severe acute respiratory syndrome (SARS) in Hong Kong during the outbreak in spring 2003. We investigated the immunomodulating effects of an innovative TCM regimen derived from two herbal formulas (Sang Ju Yin and Yu Ping Feng San) for treating febrile diseases. Thirty-seven healthy volunteers were given the oral TCM regimen daily for 14 days. Peripheral venous blood samples were taken on days 0, 15 and 29 for hematology, biochemistry and immunology tests, including the measurement of blood lymphocyte subsets and plasma T-helper lymphocyte types 1 and 2 cytokines and receptor. After 3 months, 23 of the volunteers participated in a control study without TCM treatment for the same time course of blood tests. Two volunteers withdrew on day 2, due to headache and dizziness. All others remained well without any side effects. No participants showed significant changes in their blood test results, except that the T-lymphocyte CD4/CD8 ratio increased significantly from 1.31 +/- 0.50 (mean +/- SD) on day 0 to 1.41 +/- 0.63 on day 15 (p < 0.02), and reduced to 1.32 +/- 0.47 on day 29 (p < 0.05). In the control study, there were no changes in the CD4/CD8 ratio. The transient increase in CD4/CD8 ratio was likely due to the TCM intake. We postulate that the administration of the innovative TCM may have beneficial immunomodulatory effects for preventing viral infections including SARS.

This study was carried out to provide current information on neuromeningeal cryptococcosis at the Infectious Diseases Clinic in Fann Teaching Hospital in Dakar. Epidemiological, clinical, biological and therapeutic data were collected retrospectively from files of patients treated between 1999 and 2003. A total of 45 cases including 34 in HIV-positive patients were analyzed. The prevalence of neuronieningeal cryptococcosis in H1V-infected patients was 2.9% in 2000 and, 7.9% in 2003. Only 6 patients had been using antiretroviral therapy. The male-to-female sex ratio was 2 and mean age was 34 years (range, 18-61 years). Clinical presentation involved fever (73.3%), persistent headache (86.7%), vomiting (66.7%), meningeal syndrome (60%), coma (20%), convulsion (13.3%), focal neurological deficit (15.6%), and cranial nerve dysfunction (11.1 %). The CD4-cell count was less than 200/mm3 in 14 of 15 patients tested. Cerebrospinal fluid was clear in most cases (88.9%) and lytuphocytic in half (52%) with a mean albumin concentration of 0.79 g/l. Positive results were obtained with India ink smears in 35 of 45 cases, cultures in 30 of 31 cases and cryptococcic antigen detection in CSF in 9 of 9 cases. The most frequently used antifungal drug was fiuconazole (93%). The mortality rate was 71.1% (32 deaths) overall and reached 78.9% in patients with less than 20 cells/mmm3 in CSF (78.9%). Three measures are necessary for control of neuromeningeal crytococcosis: routine screening in severely immunodeficient HIV patients, distribution of effective systemic antifungal drugs and primary prevention by widespread use of antiretroviral therapy.

This 34-year-old man with a 10-year history of HIV infection presented with an acute onset of severe headache, fever, nausea, vomiting, and left-sided weakness. Computed tomography (CT) scanning demonstrated diffuse subarachnoid hemorrhage (SAH), and subsequent CT angiography revealed multiple large and giant intracranial aneurysms with diffuse vasculopathy. The patient's CD4-positive cell count was low, although he had been receiving combination antiretroviral therapy and his viral load was undetectable. The preponderance of the literature on HIV-infected patients with intracranial vascular involvement has concerned children in whom there is a high viral load. In such children, appropriate antiretroviral therapy may result in the complete resolution of these vascular abnormalities. In the present study, the authors report on the unique case of an HIV-infected adult patient who presented with SAH, diffuse intracranial vasculopathy, and multiple giant and fusiform aneurysms, despite having received adequate antiretroviral treatment and demonstrating an undetectable viral load. Intracranial vascular involvement in these patients may become increasingly common as the management of HIV infection continues to improve and afflicted patients survive for longer periods.

Cryptococcal meningitis usually occurs among HIV-positive patients with CD4 counts less than 100 cells/mm(3) and manifests as headaches, fevers, and mental status changes. We present an unusual case of cryptococcal meningitis in a 34-year-old HIV-positive man presenting as a large abdominal cyst at the ventriculoperitoneal shunt site despite receiving highly active antiretroviral therapy (HAART) for more than 5 years and having a CD4 count more than 400 cells/mm(3).

We report a 16-year-old male patient who presented with headache, behavior changes, and fever. His cerebral spinal fluid and blood cultures grew Cryptococcus neoformans. His laboratory evaluation was negative for human immunodeficiency virus infection but flow cytometry revealed low CD4(+) count of 39 cells/mm(3) and CD4:CD8 ratio of 0.43. He was initially treated with antifungal agents with only partial clinical improvement, and he was discharged to home on oral fluconazole and prophylactic co-trimoxazole. After discharge, he continued to have persistent headache and recurrent episodes of vomiting. He was readmitted several times because of worsening of meningitis symptoms and received prolonged courses of multiple antifungal therapy, with clearance of infection from the central nervous system. He was subsequently placed on prophylactic therapy with fluconazole. His peripheral CD4(+) cell count remained low after resolution of his meningitis. Eight months after the initial diagnosis, recombinant IL-2 therapy was initiated and within a few months, his CD4(+) cell count started to increase. Treatment with rIL-2 and prophylactic antifungal therapy continued and he has been asymptomatic for almost 20 months so far. This case is the first reported pediatric idiopathic CD4(+) T-lymphocytopenia case with cryptococcal meningitis that was successfully treated by the addition of rIL-2 therapy to antifungal therapy.
