Coreia - Em Busca do Diagnóstico!

Introdução: A coreia, isolada ou associada a outros distúrbios do movimento, pode serforma de apresentação de diversas patologias. A história clínica e o exame objectivo sugerem o diagnóstico e orientam a investigação da generalidade das situações de coreia, sendo a sua etiologia identificada na maioria dos casos. Relato de caso: Adolescente do sexo feminino, 14 anos, residente em Angola, com movimentos involuntários dos membros e face, interpretados como coreia e discinésia oro-facial, e hipomobilidade do membro superior direito com cinco dias de evolução associada a labilidade emocional. Sem história sugestiva de doença estreptocócica, infeccções recentes ou exposição a fármacos. Avaliação laboratorial, incluindo função tiroideia, ceruloplasmina sérica, exame citoquímico e imunoelectroforese do líquor, sem alterações relevantes. Pesquisa de tóxicos negativa. Ressonância magnética crânio-encefálica e electroencefalograma normais. Evidência ecocardiográfica de insuficiência mitral ligeira sem aspectos sugestivos de cardite reumática. Exame bacteriológico do exsudado faríngeo negativo e doseamento de anticorpos anti-estreptococo negativo. Apesar destes resultados realizou penicilina benzatínica. Do restante estudo infeccioso destaca-se serologia compatível com infecção a Borrelia burgdorferi sem envolvimento neurológico. O doseamento de anticorpos anti-N-methyl-D-aspartate receptor (ac anti-NMDAR) foi positivo no soro. Iniciou tratamento sintomático com carbamazepina e haloperidol com resolução das queixas. A segunda amostra para pesquisa de ac anti-NMDAR no líquor e sangue foi negativa. Conclusões: O facto de não haver confirmação de doença estreptocócica prévia, não nos permite assumir a coreia de Sydenham, causa mais frequente de coreia em pediatria. Como a restante investigação não foi conclusiva deverá esta doente ser seguida a longo prazo; talvez a evolução nos venha o dar o diagnóstico final.

Five Cases of Atypical Rickettsial Infections

Background: Rickettsia conorii is the most frequent species of RickettsiaI causing disease in Portugal. In general the disease manifests itself by fever, exanthema, headaches and the presence of an eschar. However atypical forms can be present and physicians should be aware. Aims: Analyse the atypical presentation of rickettsiosis. Material and Methods: Children admitted at the CHLC Hospital from 2000 to 2010 with atypical presentation of rickettsiosis. Clinical diagnosis was confirmed by serology and molecular techniques (PCR). Results: Five cases of children with a median age of 2 years, 1 of which female, were admitted between June and August. The diagnoses were: myositis (1), synovitis (1), cholecystitis (1), orchiepididymitis (1) and meningitis (1). Myositis developped with functional disability, CPK 9600 U/L, lower limbs’ edema, hypoalbuminemia (1,6 g/dL) and arterial hypertension. Synovitis developped with functional disability, synovial fluid increase and CRP 16,2 mg/dL. The child with cholecystitis had abdominal pain, intraabdominal fluid increase, leukopenia (1900/μL), thrombocytopenia (75000/μL) and CRP 15,3 mg/dL. Orchiepididymitis developped with testicle’s inflammatory signs, leukopenia (2900/μL), thrombocytopenia (90000/μL) and CRP 14,45 mg/dL. The patient with meningitis, who had pleocytosis (320 cells/μL), hyperproteinorrachia (284 mg/dL), hypoglicorrachia (36 mg/dL), presented only with fever and headaches. The tache noire and the classical triad were present in 3/5 cases. The clinical course was favourable in all cases. Antibodies against Rickettsia of spotted fever group were detected in 3/5 cases. In one patient Rickettsia conorii Malish strain was identified by PCR and sequencing. Conclusions: Rickettsial infection may present itself unusually. In a country of high prevalence, especially during summer months and in the presence of an inoculation eschar, it is of the uttermost importance to study the atypical presentations for a possible rickettsial infection.

Sífilis congénita : caracterização da infecção e avaliação de técnicas laboratoriais para o seu diagnóstico

RESUMO: Um dos maiores problemas da sífilis é a infecção intra-uterina do feto, que pode resultar em morte fetal com aborto espontâneo. Os objectivos desta tese foram comparar os cinco testes serológicos para o diagnóstico de sífilis congénita e optimizar e aplicar a várias amostras clínicas, colhidas de indivíduos com suspeita de infecção por Treponema pallidum, uma técnica de PCR-Multiplex e uma técnica de PCR em tempo real. Na globalidade dos soros estudados obtiveram-se os seguintes resultados: o RPR reactivo em 87/517; TPHA reactivo em 135/517; e EIA reactivo em 127/517. A pesquisa de anticorpos específicos de tipo IgM foi efectuada em 33 soros sendo estudada pelas técnicas de imunofluorescência indirecta e de westernblot. Quanto aos resultados obtidos pelas duas técnicas, o teste FTA-Abs-IgM demonstrou reactividade em 3/33, enquanto que a técnica de westernblot-M, apresentou reactividade em 18/33. Para a avaliação de uma técnica de PCR-TR, foram estudadas 318 amostras de 236 indivíduos classificados, com base em critérios clínicos e laboratoriais, em diferentes estádios de infecção por Treponema pallidum e em indivíduos sem infecção por aquele microrganismo. Relativamente a estas técnicas foi possível observar amplificação de ADN de Treponema pallidum em 133/318 pela técnica de PCR-TR e 90/318 pela técnica de PCR-Multiplex. Mediante os resultados obtidos e de outros estudos efectuados parece poder concluir-se que o teste EIA é o mais indicado para o rastreio da infecção por Treponema pallidum, devendo um resultado reactivo por esta técnica, ser confirmado com a realização de um teste não treponémico (RPR). Relativamente ao diagnóstico de infecção congénita, o teste westernblot para pesquisa de anticorpos específicos de tipo IgM, parece ser o mais apropriado. A técnica PCR-TR, parece ser a mais indicada, pois apresenta uma maior sensibilidade e especificidade que a PCR-Multiplex.----------------- ABSTRACT:The syphilis major problem is the intrauterine infection of the fetus, which may result in fetal death with spontaneous abortion. The objectives of this thesis were to compare the five serological tests for the diagnosis of congenital syphilis and optimize and apply several clinical samples taken from individuals suspected of infection with Treponema pallidum, a PCR-Multiplex and real-time PCR. In all sera studied were obtained the following results: the RPR reactive in 87/517; reactive TPHA in 135/517, and 127/517 in reactive EIA. The search for specific IgM antibodies was performed on 33 sera that were studied by indirect immunofluorescence and westernblot. The results obtained by both techniques, the test FTA-Abs-IgM showed reactivity in 3/33, while the technique westernblot-M, showed reactivity in 18/33. For an RT-PCR evaluation, we studied 318 samples from 236 individuals classified based on clinical and laboratory criteria at different stages of infection by Treponema pallidum and in individuals without infection by that organism. For these techniques it was possible to observe ADN amplification of Treponema pallidum in 133/318 by RT-PCR and 90/318 by PCR-Multiplex. Based on obtained results and in other studies seems that we can conclude that the EIA test is the most suitable for Treponema pallidum screening infection, and a reactive result by this technique, should be confirmed with the realization of a non-treponemal test (RPR). For the congenital infection diagnosis, testing for antibodies westernblot specific IgM appears to be the most appropriate. The RT-PCR seems to be the most suitable, since it has a higher sensitivity and specificity than the PCR-Multiplex.

Hipersonolência Diurna. Narcolepsia, Qual a Etiologia?

Introdução: A narcolepsia é uma doença do sono REM com desregulação do ciclo de sono-vigília, consequente sonolência diurna e eventual associação a alucinações hipnagógicas, paralisia do sono e cataplexia. A sua prevalência é de 0,05 a 0,02% no adulto mas desconhecida na idade pediátrica. Caso clínico: Criança de seis anos, previamente saudável com sonolência excessiva até 18 horas/dia e discinésia oromandibular, desequilíbrio na marcha e movimentos coreiformes dos membros superiores. Duas semanas antes realizara vacinação para a gripe pandémica. Registou-se ainda hiperfagia diurna e nocturna durante cinco dias com resolução espontânea, episódios de cataplexia perante riso e alterações emocionais e tremor da cabeça e dos membros superiores com melhoria clínica progressiva após oito dias. Realizou RMN-CE e EEG sem alterações. O exame líquido céfalo-raquidiano e PCR para painel de vírus herpes, Mycoplasma pneumoniae e enterovírus negativas. Nesta fase realizou polissonografia com teste de latências múltiplas do sono (TLMS) sem alterações. Exame cultural do exsudado faríngeo, TASO e anticorpo AntiDnase B negativos. Da exaustiva investigação que realizou apresentava serologias ELISA e WB compatíveis com infecção por Borrelia burdorferi, pelo que cumpriu ceftriaxone 14 dias. Serologias para influenza A mostraram IgM 39 UA/mL com IgG 194 UA/mL com segunda amostra com IgM 43 UA/mL e IgG 162 UA/mL (VR IgM<20;IgG<20). O estudo da autoimunidade revelou ANA 1/320, anticorpos anticardiolipina e antinucleares extraíveis negativos. Restantes autoanticorpos e doseamento de complemento normal. Anticorpos Anti-NMDA e VKCG negativos. Doseamento de hipocretina muito diminuído com HLA DR2 e DQB1*0602 presentes. A polissonografia com TLMS, sete meses após a primeira, confirmou sonolência excessiva com quatro inícios do sono REM sugestivos de narcolepsia. Faz terapêutica com metilfenidato, a sonolência diurna diminuiu e cumpre o seu horário escolar sem limitações. Comentários: O diagnóstico de narcolepsia foi sugerido pela clínica e confirmado pelo teste de latências múltiplas. O valor de hipocretina diminuído pode sugerir uma etiologia autoimune. Uma infecção como a borreliose ou a vacinação prévia para H1N1, responsabilizada por outros casos de narcolepsia podem ter sido desencadeantes de uma alteração imunitária responsável pela doença, nesta criança com a susceptibilidade HLA DR2 e DBQ1*0602.

Tromboembolismo Pulmonar Associado a Infecção VIH

A presença de anticorpos antifosfolípidos é frequente em doentes com infecção VIH principalmente em fases avançadas da doença. Apesar da elevada prevalência de anticorpos antifosfolípidos, a sua associação a fenómenos trombóticos é rara, estando apenas descritos alguns casos. Os autores apresentam um caso clínico cuja manifestação inaugural de uma infecção VIH foi um tromboembolismo pulmonar associado á presença de anticoagulante lúpico.

ABO-Incompatible Liver Transplantation in Acute Liver Failure: A Single Portuguese Center Study

INTRODUCTION: ABO-incompatible liver transplantation (ABOi LT) is considered to be a rescue option in emergency transplantation. Herein, we have reported our experience with ABOi LT including long-term survival and major complications in these situations. PATIENT AND METHODS: ABOi LT was performed in cases of severe hepatic failure with imminent death. The standard immunosuppression consisted of basiliximab, corticosteroids, tacrolimus, and mycophenolate mofetil. Pretransplantation patients with anti-ABO titers above 16 underwent plasmapheresis. If the titer was above 128, intravenous immunoglobulin (IVIG) was added at the end of plasmapheresis. The therapeutic approach was based on the clinical situation, hepatic function, and titer evolution. A rapid increase in titer required five consecutive plasmapheresis sessions followed by administration of IVIG, and at the end of the fifth session, rituximab. RESULTS: From January 2009 to July 2012, 10 patients, including 4 men and 6 women of mean age 47.8 years (range, 29 to 64 years), underwent ABOi LT. At a mean follow-up of 19.6 months (range, 2 days to 39 months), 5 patients are alive including 4 with their original grafts. One patient was retransplanted at 9 months. Major complications were infections, which were responsible for 3 deaths due to multiorgan septic failure (2 during the first month); rejection episodes (4 biopsy-proven of humoral rejections in 3 patients and 1 cellular rejection) and biliary. CONCLUSION: The use of ABOi LT as a life-saving procedure is justifiable in emergencies when no other donor is available. With careful recipient selection close monitoring of hemagglutinins and specific immunosuppression we have obtained acceptable outcomes.

Transplant Glomerulopathy: Clinico-Pathologic Features

Transplant glomerulopathy is a sign of chronic kidney allograft damage. It has a distinct morphology and is associated with poor allograft survival. We aimed to assess the prevalence and clinic-pathologic features of transplant glomerulopathy, as well as determine the functional and histological implications of its severity. We performed a single-centre retrospective observational study during an eight-year period. Kidney allograft biopsies were diagnosed and scored according to the Banff classification, coupled with immunofluorescence studies. The epidemiology, clinical presentation, outcomes (patient and graft survival) and anti-HLA alloantibodies were evaluated. Transplant glomerulopathy was diagnosed in 60 kidney transplant biopsies performed for clinical reasons in 49 patients with ABO compatible renal transplant and a negative T-cell complement dependent cytotoxicity crossmatch at transplantation. The estimated prevalence of transplant glomerulopathy was 7.4% and its cumulative prevalence increased over time. C4d staining in peritubular capillaries (27.6%) was lower than the frequency of anti-HLA antibodies (72.5%), the majority against both classes I and II. Transplant glomerulopathy was associated with both acute (mainly glomerulitis and peritubular capillaritis) and chronic histologic abnormalities. At diagnosis, 30% had mild, 23.3% moderate and 46.7% severe transplant glomerulopathy. The severity of transplant glomerulopathy was associated with the severity of interstitial fibrosis. Other histological features, as well as clinical manifestations and graft survival, were unrelated to transplant glomerulopathy severity.

Infliximab in Recalcitrant Generalized Pustular Arthropatic Psoriasis

Generalized pustular psoriasis is an unstable inflammatory type of psoriasis, with widespread areas of erythema and sterile pustules, associated with fever and systemic symptoms. Infliximab is a monoclonal antibody with anti-TNFalpha activity, approved for use in psoriasis. We describe a male patient with a long history of stable arthropathic psoriasis, hospitalized with a generalized pustular psoriasis and acute exacerbation of articular complaints. The disease was resistant to multiple therapies (acitretin, methotrexate and corticosteroids), so the patient was started on infliximab, with a very rapid response of both cutaneous and articular symptoms. He had complete clearing of lesions at week 12, and marked improvement of the articular symptoms. No recurrence occurred at 8 months of follow-up with infliximab every 8 weeks. Infliximab had an extremely rapid therapeutic action response on a recalcitrant generalized pustular psoriasis. The articular response was also excellent, with significant improvement of quality of life.

The Role of the Humoral Immune Response in the Molecular Evolution of the Envelope C2, V3 and C3 Regions in Chronically HIV-2 Infected Patients

BACKGROUND: 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 glycosylation in the C2V3C3 region were analysed as a function of the number of CD4+ T cells and the anti-C2V3C3 IgG and IgA antibody reactivity RESULTS: The mean intra-host nucleotide diversity was 2.1% (SD, 1.1%), increasing along the course of infection in most patients. Diversity at the amino acid level was significantly lower for the V3 region and higher for the C2 region. The average divergence rate was 0.014 substitutions/site/year, which is similar to that reported in chronic HIV-1 infection. The number and position of positively selected sites was highly variable, except for codons 267 and 270 in C2 that were under strong and persistent positive selection in most patients. N-glycosylation sites located in C2 and V3 were conserved in all patients along the course of infection. Intra-host variation of C2V3C3-specific IgG response over time was inversely associated with the variation in nucleotide and amino acid diversity of the C2V3C3 region. Variation of the C2V3C3-specific IgA response was inversely associated with variation in the number of N-glycosylation sites. CONCLUSION: The evolutionary dynamics of HIV-2 envelope during chronic aviremic infection is similar to HIV-1 implying that the virus should be actively replicating in cellular compartments. Convergent evolution of N-glycosylation in C2 and V3, and the limited diversification of V3, indicates that there are important functional constraints to the potential diversity of the HIV-2 envelope. C2V3C3-specific IgG antibodies are effective at reducing viral population size limiting the number of virus escape mutants. The C3 region seems to be a target for IgA antibodies and increasing N-linked glycosylation may prevent HIV-2 envelope recognition by these antibodies. Our results provide new insights into the biology of HIV-2 and its relation with the human host and may have important implications for vaccine design.

Análise das Serologias para Infeções do Grupo TORCH e do Rastreio para Streptococcus do Grupo B na População de Grávidas de uma Maternidade

Introdução: O rastreio para doenças de transmissão vertical na gravidez contribuiu para a melhoria dos cuidados perinatais. Objectivo: Avaliar o resultado de serologias para infeções do grupo TORCH e do rastreio para Streptococcus do grupo B (SGB) numa amostra de grávidas de uma maternidade, estudar a influência da idade e da nacionalidade, e identificar casos de infecção congénita. Material e Métodos: Estudo não probabilístico de prevalência de imunidade e infecção durante a gravidez. Resultados: Registámos 9508 serologias TORCH e 2639 resultados de rastreio para SGB. A taxa de imunidade para rubéola foi 93,3%, significativamente mais elevada em portuguesas; 25,7% das mulheres tinham IgG positiva para Toxoplasma goondii; a taxa foi mais elevada nas mulheres mais velhas e entre estrangeiras; encontrámos IgG positiva para vírus citomegálico humano (CMV) em 62,4%; não houve variação com a idade. O VDRL foi reactivo em 0,5%; 2,3% das mães tinham AgHBs positivo, mais frequente nas estrangeiras; 1,4% tinha anticorpos para o vírus da hepatite C e 0,7% tinha VIH positivo. Não houve casos declarados de infeção congénita; 13,9% das mulheres eram portadoras de SGB. Discussão: A elevada taxa de imunidade para a rubéola é resultado da política nacional de vacinação. A baixa taxa de imunidade para a toxoplasmose torna mais dispendioso o seguimento das grávidas. A elevada prevalência do CMV está de acordo com o encontrado na comunidade. Para algumas infeções foram encontradas diferenças de acordo com a nacionalidade. Conclusão: O conhecimento da imunidade e infecção na população é um instrumento importante para o planeamento dos rastreios durante a gravidez.

Evolution of the Human Immunodeficiency Virus Type 2 Envelope in the First Years of Infection is Associated with the Dynamics of the Neutralizing Antibody Response

Background: Differently from HIV-1, HIV-2 disease progression usually takes decades without antiretroviral therapy and the majority of HIV-2 infected individuals survive as elite controllers with normal CD4+ T cell counts and low or undetectable plasma viral load. Neutralizing antibodies (Nabs) are thought to play a central role in HIV-2 evolution and pathogenesis. However, the dynamic of the Nab response and resulting HIV-2 escape during acute infection and their impact in HIV-2 evolution and disease progression remain largely unknown. Our objective was to characterize the Nab response and the molecular and phenotypic evolution of HIV-2 in association with Nab escape in the first years of infection in two children infected at birth. Results: CD4+ T cells decreased from about 50% to below 30% in both children in the first five years of infection and the infecting R5 viruses were replaced by X4 viruses within the same period. With antiretroviral therapy, viral load in child 1 decreased to undetectable levels and CD4+ T cells recovered to normal levels, which have been sustained at least until the age of 12. In contrast, viral load increased in child 2 and she progressed to AIDS and death at age 9. Beginning in the first year of life, child 1 raised high titers of antibodies that neutralized primary R5 isolates more effectively than X4 isolates, both autologous and heterologous. Child 2 raised a weak X4-specific Nab response that decreased sharply as disease progressed. Rate of evolution, nucleotide and amino acid diversity, and positive selection, were significantly higher in the envelope of child 1 compared to child 2. Rates of R5-to-X4 tropism switch, of V1 and V3 sequence diversification, and of convergence of V3 to a β-hairpin structure were related with rate of escape from the neutralizing antibodies. Conclusion: Our data suggests that the molecular and phenotypic evolution of the human immunodeficiency virus type 2 envelope are related with the dynamics of the neutralizing antibody response providing further support for a model in which Nabs play an important role in HIV-2 pathogenesis.

Expressão em Escherichia coli de antigénios do Cell fusing agent virus (Flaviviridae: Flavivirus) como proteína de fusão

RESUMO: O Cell Fusing Agent Vírus (CFAV), considerado como o primeiro “flavivírus específicos de insectos” (ISF), parece estar exclusivamente adaptado aos seus hospedeiros, não replicando em células de vertebrados. Apesar de ter sido identificado há mais de três décadas (1975), a verdade é que muito pouco se conhece sobre a sua biologia. Dado o seu parentesco filogenético com alguns outros flavivírus encontrados naturalmente em mosquitos de diferentes géneros colhidos em diferentes regiões do globo, este vírus poderá ser usado como modelo para o estudo de ISF. No entanto, necessitam do desenvolvimento de ferramentas básicas, tais como clones moleculares ou baterias de soros contendo anticorpos que reconheçam uma ou mais proteínas codificadas pelo genoma viral, produzidas, por exemplo, a partir de antigénios virais produzidos de forma recombinante. Com este trabalho pretendeu-se a optimização de protocolos que permitiram a expressão e purificação parcial de quatro proteínas [duas proteínas estruturais (C e E) e duas não estruturais (NS3hel e NS5B)] do CFAV em E. coli, todas elas produzidas como proteínas de fusão com “caudas” (tags) de hexahistidina nos seus extremos carboxilo. Para a expansão do CFAV foram utilizadas células Aedes albopictus (C6/36). Após a realização da extracção do RNA viral e a obtenção de cDNA, procedeu-se amplificação, por RT-PCR, das regiões codificantes das proteínas C, E, NS3hel e NS5B, utilizando primers específicos. Os quatro fragmentos de DNA foram independentemente inseridos no vector pJTE1.2/blunt usando E. coli NovaBlue como hospedeira de clonagem e, posteriormente, inseridos em vectores de expressão pET-28b e pET-29b usando E. coli BL21(DE3)pLysS e Rosetta(DE3)pLysS como hospedeiras de expressão. Após da indução, expressão e purificação das proteínas recombinantes C, E, NS3hel e NS5B, foi confirmada a autenticidade destas proteínas produzidas através do método Western Blot com um anticorpo anti-histidina. --------- ABSTRACT: The Cell Fusing Agent virus (CFAV) considered as the first "insect- specific flavivirus" (ISF) and seems to be uniquely adapted to their hosts, not replicating in vertebrate cells. Although it has been known for more than three decades (1975), the truth is very little is known about its biology. Given its close phylogenetic relationship with other flavivirus naturally circulating in various genera of mosquitoes collected from different regions of the globe, this virus could be used as a model for the study of ISF. However, such studies require the development of experimental basic tools, such as molecular clones or serum batteries containing antibodies that recognize one or more proteins encoded by the viral genome, produced, for example, from viral antigens recombinant produced. In this work, we carried out the optimization of protocols that allowed the expression and partial purification of four proteins [two structural proteins (C and E) and two nonstructural proteins (NS3hel and NS5B)] CFAV in E. coli as fusion protein for c-terminal hexahistidine tags. For the expansion of the CFAV we used Aedes albopictus (C6/36) cells. After completion of the viral RNA extraction and cDNA obtained, amplification of the coding regions of the C, E, NS5B and NS3hel proteins was carried out by RT-PCR using specific primers. The four DNA fragments were independently inserted into the vector pJTE1.2/blunt using E. coli NovaBlue as cloning host and then inserted into expression vectors pET-28b and pET-29b using E. coli BL21(DE3)pLysS and Rosetta(DE3)pLysS as expression host. After induction, expression and purification of recombinant C, E, NS3hel and NS5B proteins Western Blot analyses with an anti-histidine antibody confirmed the authenticity of these proteins produced.

The authors believe it is a valid paper and a good contribution to your Journal of Infectious Diseases. The content of the manuscript represents the views of the coauthors, and neither the corresponding author nor the coauthors have submitted duplicate or overlapping manuscripts elsewhere.

Exacerbation of Recalcitrant Cutaneous Sarcoidosis with Adalimumab - a Paradoxical Effect? A Case Report

The paradoxical adverse effects of tumor necrosis factor-alpha (TNF-alpha) antagonists have been described frequently as a result of the widespread use of these drugs. Among the TNF-alpha blocking agents, few reports exist relating the use of adalimumab in cutaneous sarcoidosis, although all of them show good results. More recently, sarcoidosis onsets have been reported with various TNF-alpha inhibitors. The current case is, to our knowledge, the first to describe the exacerbation of cutaneous lesions of sarcoidosis treated with adalimumab.
