Avaliação da tolerância e nefrotoxicidade do antimonial pentavalente administrado na dose de 40mg Sb v/kg/dia, de 12/12h, por 30 dias na forma cutaneo-mucosa de leishmaniose

Foi avaliada a função renal de 11 pacientes com leishmaniose cutâneo-mucosa tratados com antimonial pentavalente na dose de 40mg SbV/kg/dia aplicada de 12/12 horas, em esquema contínuo, durante trinta dias. No estudo, um paciente apresentou insuficiência renal reversível e dois desenvolveram alterações enzimáticas hepáticas e eletrocardiográficas sendo o esquema terapêutico interrompido. Nos demais pacientes observou-se efeitos nefrotóxicos tais como diminuição da taxa de filtração glomerular, diminuição da capacidade de concentração urinária, avaliada por um jejum hídrico de 16 horas e aumento na fração de excreção de sódio. No exame do sedimento urinário observou-se um aumento no número de leucócitos e cilindros. Os resultados encontrados neste estudo sugerem que o tratamento com antimonial pentavalente na dose de 40mg SbV/kg/dia foi menos tolerado em virtude de seus efeitos tóxicos, não parecendo apresentar índice de cura superior ao esquema atualmente preconizado de 20mg SbV/kg/dia.

Um caso de leishmaniose cutâneo-mucosa tratado com sucesso com baixa dose de antimonial pentavalente

Os autores relatam um caso de leishmaniose cutâneo-mucosa em uma paciente de 89 anos, diabética e hipertensa, tratada inicialmente com alopurinol por 10 meses não havendo cicatrização das lesões. Posteriormente, recebeu antimoniato de N-metil glucamina (glucantime) por 4 dias, na dose total de 2.380mg do Sb v, mas desenvolveu cardiotoxicidade e hipocalemia, sendo suspenso o tratamento, entretanto, evoluiu com regressão clínica total das lesões, apesar de ter recebido pequena dose desta medicação.

Effect of a booster-dose of rabies vaccine on the duration of virus neutralizing antibody titers in bovines

Humoral immune response using inactivated rabies vaccine was studied in 35 nelore cross-bred bovines of western region of São Paulo state. Ninety days after vaccination, 13 (92.8%) animals presented titers 30.5IU/ml, through mouse neutralization test. After 180 days, 9 (64.3%) sera showed titers 30.5IU/ml, after 270 days, only one (7.1%) showed a titer of 0.51IU/ml, and after 360 days, all animals showed titers < 0.5IU/ml. Group of animals receiving booster dose 30 days after vaccination presented, two months after, all with titers > 0.5IU/ml. At 180 days, 17 (80.9%) sera presented titers > 0.5IU/ml; at 270 days, 15 (71.4%), with titers 30.5IU/ml and at 360 days, 4 (19.0%), with titers 30.5IU/ml. Booster-dose ensured high levels of neutralizing antibodies for at least three months, and 240 days after revaccination, 71.4% of animals were found with titers 30.5IU/ml.

Low frequency of side effects following an incidental 25 times concentrated dose of yellow fever vaccine

In August/1999, a group of 14 adults from the staff of a private hospital in Contagem -- Minas Gerais State, Brazil, received unintentionally a 25 times concentrated dose of the 17-DD yellow fever vaccine (Bio-Manguinhos), due to a mistake at the reconstitution step. All patients were clinically and laboratorially evaluated at days 5, 13 and 35 post vaccination. Frequency of side effects and clinical observations of this group of individuals were not different from the observed in recipients immunized with normal doses of the vaccine. At the second and third evaluation none of the subjects reported symptoms. None of the patients presented abnormalities at the physical examination at none of the time points and in all cases the blood examination was normal, except for a reduced number of platelets that was detected in one subject at the first and second evaluation and reverted to normal at third evaluation. At the first evaluation point, 8 subjects were serum negative and 6 serum positive for yellow fever at the plaque reduction neutralization test. In 5 subjects the observed titre was 10 times higher as the baseline of 2.36 Log10 mUI/ml. The samples collected at second and third evaluation (13th and 35th days) demonstrated that all subjects responded to the vaccination with the exception of one that did not present a positive result in any of the samples collected. This evaluation confirms the safety of the 17-DD yellow fever vaccine.
