Detecção de imunoglobulinas IgG, IgM e IgA anti-Toxoplasma gondii no soro, líquor e saliva de pacientes com síndrome da imunodeficiência adquirida e neurotoxoplasmose

Abstract: RESUMO -Estudamos 55 pacientes com sindrome da imunodeficiência adquirida (SIDA) e neurotoxoplasmose (grupo 1); 37 pacientes com SIDA e comprometimento neurológico por outra etiologia (grupo 2) e 18 indivíduos anti-HIV negativos com manifestações neurológicas (grupo 3), pesquisando IgG, IgA e IgM anti-Toxoplasma gondii, no soro, líquor e saliva, utilizando teste ELISA, para fins diagnósticos. O valor preditivo negativo do teste para o encontro de IgG no soro foi 100% e no líquor, 92,4%. Não houve diferença ent… Show more

“…In the early days of the AIDS epidemic, diagnosis of cerebral toxoplasmosis was confirmed at autopsy (Table S5, online version only) or by needle biopsy of lesions suspected by computer tomography (CT) scan. Currently, diagnosis is aided by attempts to demonstrate live T. gondii parasites, antibodies to T. gondii or T. gondii antigens or T. gondii DNA in blood or CSF or even in saliva (Borges and Figueiredo, 2004; Vidal et al 2004; Colombo et al 2005; Meira et al 2008; Nogui et al 2009; Correia et al 2010; Mesquita et al 2010 a , b ; Meira et al 2011). Obviously, use of peripheral blood for diagnosis is less invasive and good results were obtained using quantitative serology and DNA detection in cerebral toxoplasmosis (Vidal et al 2011).…”

“…A predominância da via sexual como forma de contrair o vírus reflete o principal fator de exposição a esta infecção no nosso estado 17 , estando em concordância com estudos realizados em outros estados brasileiros, como Minas Gerais, Espírito Santo e São Paulo 12,16,19 . A neurotoxoplasmose permanece como uma das principais co-infecções causando lesões expansivas do Sistema Nervoso Central em pacientes com síndrome da imunodeficiência adquirida 18 .…”

“…Serological detection of anti-Toxoplasma IgG antibodies in immunosuppressed individuals serves as an indicator of chronic infection by the parasite, but it does not help to defi ne active disease 13 . Studies that have evaluated intrathecal synthesis of IgG have shown low sensitivity and consequently little clinical utility 13,14 .…”

In routine cerebrospinal fl uid analysis, fi ndings of moderate pleocytosis with elevated protein concentrations are nonspecifi c 13 , but increased cell counts may contribute to greater sensitivity of PCR results, as we found in a previous study 15 in which we reported on clinical variables that infl uenced and thereby improved the performance of the method.…”
