This study was conducted to provide information on the genetic diversity of human parvovirus B19 (B19V) circulating in the municipality of Niterói, Rio de Janeiro, Southeast Brazil during 1996–2006, a period with two distinct outbreaks of B19V infection: 1999–2000 and 2004–2005. A total of 27 sera from patients with erythema infectiosum and five sera from HIV-infected patients that tested positive for B19V DNA during the study period were analyzed. To genotype B19V strains, a semi-nested PCR for partial amplification of the capsid gene was performed and sequence analysis revealed that 31 sequences belonged to subgenotype 1a (G1a) of the main genotype 1 and one sequence was characterized as subgenotype 3b (G3b). The phylogenetic tree supported the division of the G1a into two well-defined clades with 1.3% of divergence. The low diversity of the G1a strains may be explained by the fact that all patients had acute B19V infection and 30/32 sera were collected during two distinct outbreaks. The G3b strain was from an HIV-infected patient who seroconverted to anti-B19 IgG antibodies in September/2005. This is the first report of G3b in the state of Rio de Janeiro.

Background. Continuous health monitoring of human immunodeficiency virus (HIV) infected patients is critical to allow uninterrupted access to antiretroviral therapy (ART) and sustained viral suppression. Despite public health effort for patient retention in care, many HIV-infected patients fail to maintain effective engagement in Health Services. This study reports the attendance of HIV infected individuals for routine exams in a Brazilian outpatient clinic. Methods. Patients were enrolled in two moments, 2010/2011 and 2014/2015, as they attended the public service for monitoring HIV infection status. The individuals that agreed to participate the study signed an informed consent and completed a structured questionnaire. Results. Of 58 initially expected patients, only 31 participated in the second part of the study. The reasons for these individuals not returning to the health service during the study period were not related to death (1.7%) and the majority of them still remained enrolled in the service and in follow-up. Discussion. The difficulty of HIV infected patients in returning to healthcare services have been reported by several authors. Among the barriers that prevent monitoring, we suggest that noncompliance may also be linked to years of study. However this subject needs more investigation.

Objective: Compare the anti-T. gondii IgG titer between HIV-1 infected and non HIV-1 infected pregnant women and report three cases of congenital toxoplasmosis resulting from reactivation of infection during pregnancy of HIV-1 infected women. Methods: This study was conducted among 2,270 pregnant women with chronic Toxoplasma gondii infection (absence of IgM and presence of IgG), including 82 HIV-1 infected and 2,188 non-infected women. Results: The average anti-T. gondii IgG titer was 127 for the 2,188 non-HIV-1 infected women, and 227 for the 82 HIV-1-infected women (p = 0,007). These results suggested that higher anti-T. gondii IgG titers in HIV-1-infected pregnant women may not be indicative of an elevated risk for fetal infection. In this study three cases of congenital toxoplasmosis that resulted from infection reactivation during pregnancy of HIV-1-infected women were manifested by fetal death, symptomatic infection, and infant without symptoms, respectively. In two of these women, a ten-fold increase in IgG levels above used cutoff was observed (2,320 UI/mL and 3,613 UI/mL, respectively). In the third pregnant women anti-T. gondii IgG titers during pregnancy did not rise despite the occurrence of congenital toxoplasmosis (204; 198; 172 UI/mL). Conclusions: Congenital toxoplasmosis resulting reactivation of infection during pregnancy in the studied group leads us to believe that it is a public health problem, especially in our population, in which seroprevalence of T. gondii infections is high. These findings also suggest that special attention is necessary during pregnancy, because the serologic diagnosis may not be indicative of toxoplasmosis reactivation.

We report the occurrence of congenital toxoplasmosis in three infants born to HIV infected women who had high anti-toxoplasma IgG and negative IgM during pregnancy. We briefly reviewed available literature and discussed the possible transmission mechanisms of congenital toxoplasmosis among HIV infected pregnant women. Serum samples were tested for Toxoplasma gondii IgM and IgG antibodies using commercial enzyme immunoassay and IgG-avidity tests. In the first case, fetal death occurred at 28th week of gestation. In the second case, congenital toxoplasmosis was diagnosis at 6th month of life; and in the third case, an HIV-infected newborn, congenital toxoplasmosis was asymptomatic. These cases point out to the possibility of enhanced maternal-fetal transmission of T. gondii infection by HIV-infected women chronically infected, which may have important public health consequences, considering that increasing frequency of HIV-infection has been observed among women of childbearing age around the world.

Oral opportunistic infections can lead to a range of diseases in people who are living with human immunodeficiency virus (HIV). Among them, herpes viruses are responsible for common diseases in HIV positive people. Both benign and malignant oral diseases are associated with the Epstein-Barr virus (EBV). Five cases of oral lesions from a cohort of HIV positive patients were associated with EBV detection in the oral mucosa. Active EBV deoxyribonucleic acid (DNA) was detected in three of the samples. Of the two cases with herpes simplex type 1 (HSV-1)-like ulcers, only one was associated with EBV detection. Similarly, only one candidiasis case was also EBV DNA positive. Severe immunosuppression was found in the patient with candidiasis and hairy leukoplakia. This man, who harbored the EBV-2 strain, was also positive for EBNA-2 ribonucleic acid (RNA) message and showed several symptoms indicative of disease development. This study provides baseline data on the dynamics of opportunistic oral infections in HIV infected individuals in the era of highly active antiretroviral therapy (HAART), as well as the detection of EBV markers and their link with clinical outcome.

A case of malignant neoplasm is described in which the initial manifestations were mental dysfunction and meningeal irritation, mimicking chronic or subacute meningitis. Physical examination showed cranial nerve involvement and a pelvic tumor. There was progressive deterioration, and death occurred in 2 weeks. The autopsy revealed a gallbladder adenocarcinoma, meningeal carcinomatosis, and ovarian metastasis presenting as a Krukenberg tumor. The authors emphasize the importance of including meningeal carcinomatosis as a possibility in the differential diagnosis of non-characteristic clinical pictures, as well as the importance of the cerebrospinal fluid cytologic examination, repeated as needed, in order to confirm this diagnosis.

Objective: the detection rate of Epstein-Barr virus (EBV) is higher in people living with human immunodeficiency virus (HIV). In an attempt to contribute to our epidemiological understanding of this coinfection and to investigate the activity of EBV in normal oral mucosa, we performed a cross-sectional study with HIV-positive patients. Methods: oral smears from 145 HIV-positive patients were collected between March 2010 and March 2011. Nested polymerase chain reaction (PCR) and reverse transcriptase-PCR (RT-PCR) were used to genotype EBV and to detect EBNA-2 expression, respectively. Results: EBV DNA was detected in 48.3% of the study participants, of whom 32.85% were EBV-1 and 45.71% were EBV-2 carriers. Additionally, 14.28% were coinfected with both types. EBNA-2 mRNA was expressed in 45.7% of the EBV -positive samples, including 20.0% with EBV-1 only, 20.0% with EBV-2 only and 1.4% with both genotypes. Immune status affected the overall EBV infection, and EBV-2 positivity was significantly correlated with sexual lifestyle of the participants. EBV co-infection with both viral types was dependent upon HIV viral load and the activity of the EBNA-2 gene. Conclusion: we report a high prevalence of active EBV in the oral mucosa of asymptomatic HIV-seropositive individuals. This study addresses the need for monitoring and treatment of HIV-infected patients with EBV reactivation.

No periodo de maio / 94 a novembro / 95, 24 casos de parvovirose humana foram atendidos no Servico de Doencas Infecciosas e Parasitarias do Hospital Universitario Antonio Pedro, Niteroi - RJ. Amostras sanguineas para a deteccao de IgM (ensaio imunoenzimatico por captura) foram positivas do 1o ao 27o dia apos o inicio do exantema. Os sinais e sintomas classicos do eritema infeccioso foram observados em 8 (33,3%) dos casos e apenas em criancas. Oito pacientes (6 adultos e 2 criancas) apresentaram poliartropatia simetrica, vista mais frequentemente em mulheres. Os resultados deste trabalho demonstram que o diagnostico da parvovirose humana e dificil quando a doenca nao apresenta quadro clinico classico e, devido ao frequente envolvimento das articulacoes, tal infeccao deve ser considerada no diagnostico diferencial da artrite reumatoide na sua fase inicial.

Purpose To describe an unusual case of disseminated sporotrichosis with intraocular involvement. Design Interventional case report. Results An 18-year-old man presented with disseminated ulcerated skin lesions. Fundus examination showed fluffy opacities in the vitreous and a retinal granuloma in the left eye. Biopsy of the skin lesion and lymph node showed the presence of numerous fungus cells. Culture was positive for the diagnosis of disseminated sporotrichosis. Conclusion Although intraocular infection due to Sporothrix schenckii is uncommon, it can occur in case of disseminated sporotrichosis. Systemic therapy is a successful means to control skin and ocular sporotrichosis.

Erythrovirus B19 (B19V) infection may cause red cell aplasia in patients infected with human immunodeficiency virus (HIV). The introduction of highly active antiretroviral therapy (HAART) has improved the immune function of these patients by modifying the course of B19V infection. The purpose of this study was to estimate the frequency of B19 seroconversion in a cohort of HIV-infected patients and evaluate the occurrence of B19V-related anaemia during the seroconversion period. Adult HIV-infected patients were studied at a public hospital in Niterói, state of Rio de Janeiro, Brazil. IgG and IgM antibodies against B19V were detected by an enzyme-linked immunosorbent assay and B19 viraemia was assayed by polymerase chain reaction. Medical records were reviewed for any clinical evaluation of anaemia. Seroconversion was detected in 31.8% of the 88 individuals who began the study as anti-B19V IgG-negative. No clinical manifestations of B19V infection were detected during the period of seroconversion. Patients who seroconverted were 5.40 times more likely to have anaemia than those who did not [odds ratio 5.40 (95% confidence interval: 1.33-22.93)]. Anaemia was detected in eight patients. All patients recovered from anaemia by either beginning or continuing HAART, without requiring blood transfusions. In the HAART era, B19V infection may only be associated with a course of disease characterised by less severe chronic anaemia. This milder course of B19V-associated disease is likely due to the increased immune function of HAART-treated patients.

Parvovirus B19 (B-19) may cause chronic anaemia in immunosuppressed patients, including those infected with human immunodeficiency virus (HIV). We studied single serum samples from 261 consecutive HIV-infected patients using an enzyme immunoassay to detect IgG antibodies to B-19. The seroprevalence of B-19-IgG was 62.8%. The differences in seroprevalence across gender, age, educational categories, year of collection of the serum samples, clinical and antiretroviral therapy characteristics, CD4+ count, CD4+ and CD8+ percentage and CD4+/CD8+ ratios were neither substantial nor statistically significant. There was a non-significant, inverse association between B-19 seropositivity and plasma HIV load and haemoglobin level. Our results indicated that 37.1% of patients might be susceptible to B-19 infection and remained at risk for being infected, mainly during epidemic periods. As B-19 infection can be treated with immune globulin preparations, it may be included in the diagnostic approach toward chronic anaemia in HIV-infected patients.

OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males). ECG and echocardiogram were also obtained every six months. After death, macro- and microscopic examinations were also performed. RESULTS - The most frequent causes of referral to the hospital were: diarrhea or repeated pneumonias, tuberculosis, toxoplasmosis or Kaposi sarcoma. The most frequent findings were acute or chronic pericarditis (42%) and dilated cardiomyopathy (19%). Four patients died of cardiac problems: infective endocarditis, pericarditis with pericardial effusion, bacterial myocarditis and infection by Toxoplasma gondii. CONCLUSION - Severe cardiac abnormalities were the cause of death in some patients. In the majority of the patients, a good correlation existed between clinical and anatomical-pathological data. Cardiac evaluation was important to detect early manifestations and treat them accordingly, even in asymptomatic patients.

Background: Most cardiovascular abnormalities in patients infected with the human immunodeficiency virus (HIV) have been associated with myocardial damage directly caused by the virus. Some cases, however, may be associated with adverse effects from antiretroviral therapy (ART). New ventricular function assessment techniques are capable of detecting early changes in the cardiac function of HIV-infected patients using or not using ART. The usefulness of these techniques has been little employed in these patients. Objectives: To investigate the potential influence of antiretroviral therapy (ART) on the occurrence of subclinical left ventricular systolic dysfunction evaluated by myocardial strain rate analysis using two-dimensional speckle tracking echocardiography (2-D Echo) in treated HIV patients compared to untreated patients and healthy individuals. Methods: Sixty-eight HIV-infected patients with no cardiovascular symptoms, normal left ventricular (LV) ejection fraction (> 0.55 on 2-D Echo) were divided into three groups: 11 patients not using antiretroviral therapy (NT), 24 using protease inhibitor (PI) and 33 using non-nucleoside reverse transcriptase inhibitor (NNRTI). We also studied 30 normal non-HIV infected individuals (Ctrl). Demographic, clinical, biochemical and anthropometric data were collected. Preliminary transthoracic echocardiography included study of myocardial strain using two-dimensional speckle tracking. We studied strain and strain rate in the seventeen left ventricular (LV) myocardial segments in the longitudinal, circumferential and radial axes. Statistical analysis of the data was done with IBM SPSS - version 20 for Windows. Upon analysis of the data, namely the normality of independent variables in the different groups and the homogeneity of the variances between the groups, Kruskal-Wallis’ non-parametric test was done, followed by Dunn’s multiple comparison tests to test the significance of the differences between the values measured in the study groups. A significance level of 5% was adopted for decision-making on statistical tests. Results: The mean age of HIV patients was 40 ± 8.65 years and the mean age of controls was 50 ± 11.6 years (p < 0.001). Median LV global longitudinal strain (GLS) of NT patients (-17.70%), PI patients (-18.27%) and NNRTIs (-18.47%) were significantly lower than that of the Ctrl group (-20.77%; p = 0.001). There was no significant difference in mean SLG between treated patients (PI, NNRTI) and untreated (NT) patients. No significant differences were observed in mean circumferential and radial strain, nor on circumferential and radial strain rates between the NT, PI, NNRTI and Ctrl groups. Conclusion: The data suggest that HIV patients present, on myocardial strain measured by speckle tracking, signs of early LV systolic dysfunction that seem to be unrelated to the presence of ART. The prognostic significance of this condition in these patients deserves further studies. Resumo Fundamento: A maior parte das alterações cardiovasculares dos pacientes infectados pelo vírus da imunodeficiência humana (HIV) tem sido associada ao dano miocárdico causado diretamente pelo vírus. Alguns casos, porém, podem estar associados a efeitos adversos da terapia antirretroviral (TARV). Novas técnicas de avaliação da função ventricular são capazes de detectar modificações precoces na função cardíaca do paciente infectado pelo HIV em uso ou não de TARV. A utilidade dessas técnicas tem sido pouco empregada nesses pacientes. Objetivos: Investigar possível influência da terapia antirretroviral (TARV) na ocorrência de disfunção sistólica ventricular esquerda subclínica avaliada pela análise da taxa de deformação miocárdica (strain) por meio do speckle tracking ao ecocardiograma bidimensional (E2D) em pacientes portadores do HIV tratados, comparados com pacientes não tratados e indivíduos saudáveis. Métodos: Sessenta e oito pacientes infectados pelo HIV assintomáticos do ponto de vista cardiovascular, com fração de ejeção do ventrículo esquerdo (VE) normal (>0,55 pelo E2D) foram divididos em três grupos: 11 pacientes sem tratamento antirretroviral (ST), 24 em uso de inibidor de protease (IP) e 33 em uso de inibidor de transcriptase reversa não nucleosídeo (ITRNN). Foram estudados também 30 indivíduos normais não infectados pelo HIV (Ctrl). Foram coletados dados demográficos, clínicos, bioquímicos e antropométricos. A ecocardiografia transtorácica foi realizada incluindo no estudo inicial o estudo da deformação miocárdica pela técnica bidimensional (speckle tracking). Estudamos o strain e a sua taxa de deformação (strain rate) nos dezessete segmentos miocárdicos do ventrículo esquerdo (VE) nos eixos longitudinal, circunferencial e radial. A análise estatística dos dados foi feita com o programa IBM SPSS - versão 20 para Windows. Depois de analisados os dados, nomeadamente a normalidade das variáveis independentes nos diferentes grupos e a homogeneidade das variâncias entre os grupos, decidiu-se utilizar o teste não paramétrico de Kruskal-Wallis seguido dos testes de comparações múltiplas pelo procedimento de Dunn, para testar a significância das diferenças entre os valores medidos nos grupos em estudo. Foi considerado o nível de significância de 5% para a tomada de decisão nos testes estatísticos realizados. Resultados: A média das idades dos pacientes com HIV foi de 40 ± 8,65 anos e a idade média dos controles foi de 50 ± 11,6 anos (p < 0,001). Os valores medianos do strain longitudinal global do VE (SLG) dos pacientes ST (-17.70%), dos pacientes IP (-18.27%) e ITRNN (-18.47%) foram significativamente menores do que o grupo Ctrl (-20,77%; p = 0,001). Não houve diferença significante nos valores médios do SLGentre os pacientes tratados (IP, ITRNN) e não tratados (ST). Não foram observadas diferenças significantes nos valores médios do strain circunferencial e radial, nem nas taxas de deformação circunferencial e radial entre os grupos ST, IP, ITRNN e Ctrl. Conclusão: Os dados sugerem que pacientes com HIV apresentam, à análise da deformação miocárdica ao speckle tracking, sinais de disfunção sistólica incipiente do VE que parece não ter relação com a presença de TARV. O significado prognóstico dessa alteração nesses pacientes merece estudos futuros.
