Reversible posterior leukoencephalopathy secondary to indinavir-induced hypertensive crisis: A case report
2002
Reversible posterior leukoencephalopathy syndrome (RPLS) is an uncommon entity related to multiple and different pathologies, the most common being hypertensive crisis. It is believed to be secondary to the breakdown on the blood-brain barrier. At the beginning, it is undistinguishable from other leukoencephalopathies. However, the disappearance of brain lesions after removal of the potential cause, establish the differential diagnosis with other leukoencephalopathies. We present the case of an HIV-infected patient with a RPLS related to a hypertensive crisis short after the initiation of indinavir-containing highly active antiretroviral therapy. Once blood pressure was controlled and indin…
A mitochondrial antigen-antibody system in cholestatic liver disease detected by radioimmunoassay.
2007
A radioimmunoassay (RIA) was established for the detection of antimitochondrial autoantibodies (AMAs) in patient sera. AMAs were detected by RIA in 12 of 14 patients with primary biliary cirrhosis and in 3 of 29 patients with chronic active hepatitis. AMAs were detected by indirect immunofluorescence in all sera positive by RIA. In addition, two patients with primary biliary cirrhosis and one patient with chronic active hepatitis were AMA positive when tested by indirect immunofluorescence, but negative when tested by RIA. AMAs were not detected by RIA or indirect immunofluorescence in 121 further patients with various hepatic and nonhepatic diseases, including healthy controls. The RIA det…
Detection of HIV type 1 non-B subtypes in Sicily, Italy.
2004
To evaluate the presence of HIV-1 non-B subtypes in Sicily, we sequenced and genotyped HIV-1 PR and RT regions of the pol gene using plasma from 169 HIV-1-infected adult patients. All samples were obtained from a study of antiretroviral-associated resistance mutations resulting in virological failure during highly active antiretroviral therapy (HAART). Eight (4.7%) patients had the non-B HIV-1 subtype including some circulating recombinant forms (CRFs). All of these individuals acquired the infection by heterosexual transmission. The detection of HIV-1 non-B strains was significantly associated with younger age of HIV-1 acquisition. Our findings indicate, for the first time, the presence of…
Is Active Transport and Leisure-Time Physical Activity Associated With Inflammatory Markers in US Adults? A Cross-Sectional Analyses From NHANES.
2019
BACKGROUND: To investigate the association between levels of active transport and leisure-time physical activity (LTPA) with C-reactive protein, white blood cell count, body mass index, waist circumference, and lipids in a large representative sample of adults residing in the United States. METHODS: Cross-sectional data from the National Health and Nutrition Examination Survey. Adjusted multinomial logistic regressions were carried out to quantify associations between levels of self-reported active transport (or LTPA) and quintiles of anthropometric measures and serum markers. RESULTS: A total of 3248 adults were included. For serum inflammatory biomarkers, the authors observed a lower like…
Transmission of Drug-Resistant HIV Type 1 Strains in HAART-Naive Patients: A 5-Year Retrospective Study in Sicily, Italy
2010
The transmission of drug-resistant HIV-1 strains might compromise the efficacy of current first-line antiretroviral (ARV) regimens. Between 2004 and 2008, HIV-1 reverse transcriptase (RT) and protease (PR) genes of 108 ARVnaive Sicilian patients were amplified and sequenced to describe the prevalence of ARV resistance mutations among HAART-naive HIV-1-infected individuals. The frequency of transmitted drug resistance mutations (DRAMs) was determined by using genotypic interpretation algorithms. The proportion of HAART-naive HIV- 1-infected patients in Sicily increased from 18.4% to 23.5% during 2004–2008. Among naive patients, the overall prevalence of DRAMs was 15.7% [17/108; 95% CI: 9.4–2…
Role of a 48-week pegylated interferon therapy in hepatitis B e antigen positive HIV-co-infected patients on cART including tenofovir: EMVIPEG study.
2014
In hepatitis B e antigen (HBeAg) positive-HIV co-infected patients treated with combined antiretroviral therapy (cART), including tenofovir disoproxil fumarate (TDF), the rate of HBe seroconversion remains low. Whether adding pegylated interferon alfa (PegIFN) could increase the likelihood of HBeAg loss and HBe seroconversion has not been assessed.A 48-week PegIFN therapy was added to HBeAg positive-HIV co-infected patients on TDF and emtricitabine, or lamivudine for at least 6 months. The primary endpoint was HBV sustained response: HBe seroconversion with undetectable HBV DNA levels 24 weeks after completing PegIFN therapy (W72).Fifty-one patients (49 men, median age 46 years, range: 32-6…
Mycophenolate mofetil versus azathioprine in patients with chronic active ulcerative colitis: a 12-month pilot study.
2000
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) of unknown etiology frequently requiring long-term therapy for control of symptoms and prevention of relapse. Azathioprine (AZA) has been shown to be effective and safe in the treatment of chronic active UC. However, the alternatives to treatment with AZA are limited. Our aim was to compare the efficacy and safety of treatment with mycophenolate mofetil (MMF)/prednisolone versus standard immunosuppressive treatment with azathioprine (AZA)/prednisolone in patients with chronic active UC.The study was designed as an open comparison of MMF versus AZA. Twenty-four patients with active UC (Rachmilewitz scoreor =6 points) were randoml…
Burkitt lymphoma associated with human immunodeficiency virus infection and pulmonary tuberculosis: A case report.
2019
Abstract Introduction: The association of human immunodeficiency virus (HIV) infection with Burkitt lymphoma is related to the presence of Epstein Barr virus infection and the impact of the HIV antigen on the expansion of B-polyclonal cells. In Southeast Europe, the association is rare, and recognizing this is important in the therapeutic decision to increase patient survival rate. The association of HIV with Burkitt lymphoma and tuberculosis is even more rarely described in the literature. Patient concerns: We present the case of a 40-year-old patient who presented with a 3-week history of fever (max. 38.7 °C), painful axillary swelling on the right side, lumbar pain, gait disorders, heada…
A decision tree to help determine the best timing and antiretroviral strategy in HIV-infected patients.
2011
SUMMARYOptimal antiretroviral strategies for HIV-infected patients still need to be established. To this end a decision tree including different antiretroviral strategies that could be adopted for HIV-infected patients was built. A 10-year follow-up was simulated by using transitional probabilities estimated from a large cohort using a time-homogeneous Markov model. The desired outcome was for patients to maintain a CD4 cell count of >500 cells/mm3without experiencing AIDS or death. For patients with a baseline HIV viral load ⩾5 log10copies/ml, boosted protease inhibitor-based immediate highly active antiretroviral therapy (HAART) allowed them to spend 12% more time with CD4 ⩾500/mm3than…
Detection of a new 3-base pair insertion mutation in the protease gene of human immunodeficiency virus type 1 during highly active antiretroviral the…
2005
To investigate a new insertion mutation in the protease (PR) gene of human immunodeficiency virus type 1 (HIV-1) in a patient extensively pretreated with antiretroviral drugs, genotypic analyses of plasma-derived viruses were performed by sequencing segments of 1302 nucleotides in the pol gene of HIV-1. Despite optimal compliance to highly active antiretroviral therapy (HAART) the patient showed poor virological success. Nucleotide sequences of retrospective available plasma samples exhibited a previously unknown 3-bp insertion mutation, corresponding to a leucine, between codons 31 and 32 of the PR gene. This kind of mutation appears to be very rare and it does not seem to be associated wi…
