Prevalencia de Haemophilus influenzae en lactantes hospitalizados menores de 1 año en Perú

Las infecciones respiratorias agudas (IRAs) constituyen una de las cinco primeras causas de morbilidad y mortalidad a nivel mundial. Una bacteria causante de infecciones respiratorias agudas, principalmente en niños menores de 5 años es Haemophilus influenzae tipo b. “Se estima que provoca por lo menos tres millones de casos de enfermedad grave al año y alrededor de 86.000 de funciones, la mayor parte se registra en países en desarrollo”.El objetivo fue identificar Haemophilus influenzae tipo b en lactantes menores de 1año hospitalizados con diagnóstico de infección respiratoria aguda y presencia de tos coqueluchoide.

Infectious agents, Leptospira spp. and Bartonella spp., in blood donors from Cajamarca, Peru

In blood banks the sought for a series of relevant pathogens able to be transmitted by blood transfusions is widely implemented; however the presence of a series of pathogens in blood bank donations remained understudied. This is the case of some bacteria such as Leptospira spp. or Bartonella spp. Bartonella species are bloodborne, re-emerging organisms, capable of causing prolonged infections in animals and humans. Meanwhile, Leptospirosis is recognised as an emerging public health problem worldwide. Both infections are considered neglected tropical diseases.

A systematic review of the relative efficacy and toxicity of treatment regimens for HIV-associated cerebral toxoplasmosis: is trimephoprim-sulfamethaxozole a real option?

Background: Pyrimethamine and sulfadiazine (P-S) combination is effective and considered the mainstay therapy for cerebral toxoplasmosis (CT). Alternative treatment regimens are available, but their relative efficacy and tolerability are not well known. Particularly, trimephoprim-sulfamethaxozole (TMP-SMX) shows potential advantages (i.e., tolerability, posology, parenteral formulation, cost, and accessibility) but its use is infrequent when P-S is available. Methods: We searched PubMed and 4 other databases to identify randomized controlled trials (RCTs) and cohort studies comparing different regimens for the treatment of HIV-associated CT. Two independent reviewers searched and identified studies and extracted data. Risk ratios (RRs) were pooled across studies using random-effects models. Results: Nine studies were included (5 RCTs, 3 retrospective cohorts, 1 prospective cohort). Treatment with P-S has the same or better clinical efficacy than P-C or TMP-SMX in terms of partial or complete response clinical response (P-C vs P-S: RR 0.87, 95%CI 0.70-1.08; TMP-SMX vs P-S: RR 0.97, 95%CI 0.78-1.21) and radiological response (P-C vs P-S: RR 0.92, 95%CI 0.82-1.03). Safety profile in terms of skin rash (P-C vs P-S: RR 0.81, 95%CI 0.56-1.17; TMP-SMX vs P-S: RR 0.17, 95%CI 0.02-1.29), liver impairment (P-C vs P-S: RR 0.48, 95%CI 0.24-0.97) and drug discontinuation due to adverse events (P-C vs P-S: RR 0.32, 95%CI 0.07-1.47) were worse with P-S regimen. Conclusion: The available evidence fails to identify any one superior regimen for the treatment of CT. However, P-S regimen has worse safety profile than P-C or TMP-SMX. Although current evidence does not allow a definitive recommendation, use of TMP-SMX for treatment of HIV-associated CT is consistent with the available data.
