HIV-2 Integrase Polymorphisms and Longitudinal Genotypic Analysis of HIV-2 Infe...
Cavaco-Silva, J; Abecasis, A; Miranda, AC; Poças, J; Narciso, J; Águas, MJ; Maltez, F; Almeida, I; Germano, I; Diniz, A; Gonçalves, MF; Gomes, PTo characterize the HIV-2 integrase gene polymorphisms and the pathways to resistance of HIV-2 patients failing a raltegravir-containing regimen, we studied 63 integrase strand transfer inhibitors (INSTI)-naïve patients, and 10 heavily pretreated patients exhibiting virological failure while receiving a salvage raltegravir-containing regimen. All patients were infected by HIV-2 group A. 61.4% of the integrase r...
Recent advances in antiretroviral treatment and prevention in HIV-infected pati...
Maltez, F; Doroana, M; Branco, T; Valente, CPURPOSE OF REVIEW: To discuss new antiretroviral agents (ARVs) and alternative ARV treatment strategies that are currently being evaluated, and to provide an overview of the most recent advances in HIV vaccine development. RECENT FINDINGS: There is a continuous need for improvements in ARV therapy (ART) and several new ARVs are currently undergoing clinical investigation, including the non-nucleoside reverse tr...
Coreceptor Usage by HIV-1 and HIV-2 Primary Isolates: The Relevance of CCR8 Che...
Calado, M; Matoso, P; Santos-Costa, Q; Espirito-Santo, M; Machado, J; Rosado, L; Antunes, K; Mansinho, K; Lopes, MM; Maltez, F; Santos-Ferreira, MOThe human immunodeficiency virus replication cycle begins by sequential interactions between viral envelope glycoproteins with CD4 molecule and a member of the seven-transmembrane, G-protein-coupled, receptors' family (coreceptor). In this report we focused on the contribution of CCR8 as alternative coreceptor for HIV-1 and HIV-2 isolates. We found that this coreceptor was efficiently used not only by HIV-2 but...
Atypical Case of Mediterranean Spotted Fever
Figueira-Coelho, J; Martins, T; Machado, J; Maltez, FThe authors present a case of atypical severe (malignant) Mediterranean spotted fever, with a brief review on the subject. Although not previously described in Brazil, the possibility of imported cases, especially from Portuguese tourists, is real. This case report highlights the severe form of the disease and the possibility of atypical presentation with confounding differential diagnosis. A brief review of cl...
The Role of the Humoral Immune Response in the Molecular Evolution of the Envel...
Borrego, P; Marcelino, JM; Rocha, C; Doroana, M; Antunes, F; Maltez, F; Gomes, P; Novo, C; Barroso, H; Taveira, NBACKGROUND: This study was designed to investigate, for the first time, the short-term molecular evolution of the HIV-2 C2, V3 and C3 envelope regions and its association with the immune response. Clonal sequences of the env C2V3C3 region were obtained from a cohort of eighteen HIV-2 chronically infected patients followed prospectively during 2-4 years. Genetic diversity, divergence, positive selection and glyc...
Investigation and Control of a Large Outbreak of Multi-Drug Resistant Tuberculo...
Hannan, MM; Peres, H; Maltez, F; Hayward, AC; Machado, J; Morgado, A; Proença, R; Nelson, MR; Bico, J; Young, DB; Gazzard, BSAn increase in the number of new cases of tuberculosis (TB) combined with poor clinical outcome was identified among HIV-infected injecting drug users attending a large HIV unit in central Lisbon. A retrospective epidemiological and laboratory study was conducted to review all newly diagnosed cases of TB from 1995 to 1996 in the HIV unit. Results showed that from 1995 to 1996, 63% (109/173) of the Mycobacterium...
Yersínia Enterocolítica. Estudo da Seroprevalência e Apresentação de 3 Casos Cl...
Maltez, F; Machado, J; Rocha, MA; Pires Gonçalves; Morgado, A; Proença, RA Yersínia enterocolítica é um bacilo gram negativo que emergiu na últimas duas décadas como importante patogénico entérico, associado a um largo espectro de manifestações clínicas. Os autores apresentam um estudo da sua seroprevalência em 200 doentes hospitalizados e descrevem 3 casos clínicos curiosos desta infecção, incluindo um caso grave de endocardite.
Infective endocarditis.
Proença, R; Serviços de Medicina e Doenças Infecciosas, Hospital de Curry Cabral, Lisboa.; Serrano, A; Martins, T; Machado, J; Maltez, F; Coutinho, FTwo different series of patients with Infectious Endocarditis (IE), hospitalized in the same ward of Curry Cabral Hospital in Lisbon, are presented and compared. The two series were separated by a ten-year period--the first included patients observed from 1970 to 1976 and the second from 1988 to 1998. In the first series (20 patients), IE occurred mainly in patients with previous cardiac valvular lesion, the co...
Will acanthosis nigricans be a new cutaneous manifestation of human immunodefic...
Maltez, F; Serviço de Medicina I, Hospital Curry Cabral, Lisboa.; Martins, T; Morgado, A; Proença, RThe authors describe a clinical case of AIDS presented by three opportunistic infections (esophageal candidiasis, tuberculosis and atypical mycobacteriosis) and a dermatological manifestation--acanthosis nigricans--not described in medical literature as accompanying those entities. The exclusion of most common etiologies of acanthosis nigricans and its regression following treatment for those infections suggest...
Mucocutaneous pathology in HIV infection.
Lamarão, P; Serviço I de Medicina, Hospital de Curry Cabral, Lisboa.; Eliseu, T; Castro, H; Maltez, F; Machado, J; Morgado, A; Proença, RSeveral infectious, neoplastic or inflammatory skin diseases, may be early manifestations of HIV infection. We reviewed the clinical data of 226 HIV seropositive male patients with cutaneous disease, from a total of 337 inpatients at the Infectious Diseases Unit--Department of Medicine 1--Curry Cabral Hospital, from 1985 to 1991. Some considerations are made about the most common dermatological disorders: oral ...
