RESUMO
ABSTRACT Purpose: To present the results of a retrospective study regarding the clinical and economic impact of intracameral cefuroxime administration to prevent endophthalmitis during cataract surgery in a referral hospital. Methods: This study included 16,902 eyes from patients who had undergone cataract surgery between 2013 and 2017. From May 2014 onwards, all patients received routine intracameral injections of 1 mg cefuroxime (10 mg/1 mL) after phacoemulsification. The prophylactic efficacy was evaluated using the relative risk ratio, whereas the economic impact was evaluated using number needed to treat to avoid endophthalmitis. Results: Before introducing cefuroxime, 3,407 cataract surgeries were performed using the phacoemulsification technique, and 7 post-operatory cases of endophthalmitis occurred (0.2% incidence). After introducing the cefuroxime protocol, 13,495 surgeries were performed, and 4 endophthalmitis cases were registered (0.03% incidence). Cefuroxime was identified as a protective factor against the development of endophthalmitis [risk ratio = 14%, p=0.002, 95% confidence interval (CI) 95%, 4%-49%], with an economic impact of number needed to treat = 568. The potential savings with cefuroxime was approximately US $2,334.36 for every 568 patients treated. Conclusion: The incidence of endophthalmitis decreased by 86% (risk ratio = 14%, p=0.002, 95% CI, 4%-49%) after introducing intracameral cefuroxime prophylaxis at the study hospital. The results presented herein provide strong evidence for the use of cefuroxime in endophthalmitis prophylaxis after phacoemulsification surgeries, outperforming the alternative by providing both economic and clinical benefits.
RESUMO Objetivo: Apresentar os resultados de um estudo retrospectivo sobre o impacto clínico e econômico da administração de cefuroxima intracameral para prevenir endoftalmite nas cirurgias de catarata em um hospital de referência. Métodos: Este estudo incluiu 16.902 olhos de pacientes submetidos à cirurgia de catarata entre 2013 e 2017. A partir de maio de 2014, todos os pacientes receberam rotineiramente uma injeção intracameral de 1mg de cefuroxima (10mg/1mL) ao final da cirurgia de facoemulsificação. A eficácia da profilaxia foi avaliada usando o risco relativo e o impacto econômico foi avaliado com o número necessário para tratar para se evitar um caso de endoftalmite. Resultados: Antes da introdução do protocolo da cefuroxima, foram realizadas 3.407 cirurgias de catarata por facoemulsificação e ocorreram 7 casos de endoftalmite pós-operatória (incidência de 0,2%). Após a introdução do protocolo da cefuroxima, foram realizadas 13.495 cirurgias e registrados 4 casos de endoftalmite (incidência de 0,03%). A cefuroxima foi um fator de proteção no desenvolvimento de endoftalmite (risco relativo = 14%, p=0,002, Intervalo de Confiança de 95% [IC 95%], 4% - 49%) e o impacto econômico do número necessário para tratar = 568. A economia potencial com a cefuroxima foi de aproximadamente US$ 2.334,36 para cada 568 pacientes tratados. Conclusão: A incidência de endoftalmite diminuiu 86% (risco relativo = 14%, p=0,002, IC 95% 4% - 49%) desde a introdução da profilaxia com cefuroxima intracameral no hospital do estudo. Os resultados apresentados mostram forte evidência para o uso da cefuroxima na profilaxia da endoftalmite após cirurgias de facoemulsificação, por proporcionar economia de custos e benefício clínico.

PURPOSE: To describe intracameral toxic effects of cefuroxime at a higher dose than recommended in cataract surgery. METHODS: Retrospective study of 8 eyes of 8 patients who inadvertently received 12.5â¯mg/0.1â¯ml of intracameral cefuroxime due to a dilution error, at the end of the cataract surgery. All patients underwent a strict ophthalmology follow-up for 6 months. RESULTS: All patients presented with a marked anterior segment inflammation with corneal oedema that resolved completely in all cases (between 5 days and 3 months). At 6 months of follow-up a statistically significant difference was found in the corneal endothelial cell density when compared with the fellow eye (Pâ¯=â¯.038), beingâ¯<1000 cells/mm2 in 3 cases. Three patients (37.5%) showed early macular oedema, with subfoveal ellipsoid layer disruption in one case as a permanent sequel. One patient developed an optic neuropathy with associated afferent pupillary defect. CONCLUSIONS: Although 1â¯mg/0.1â¯ml of intracameral cefuroxime has been shown to reduce the incidence of endophthalmitis, its overdose can have potentially toxic eye effects in both anterior and posterior segments.

Objetivo Describir los efectos de la inyección de cefuroxima intracameral a una dosis más alta de la recomendada en cirugía de catarata. Métodos Estudio retrospectivo de 8 ojos de 8 pacientes operados de catarata en un mismo día que recibieron 12,5mg/0,1ml de cefuroxima intracameral de forma inadvertida al finalizar la cirugía, por un error en la dilución. A todos los pacientes se les realizó un seguimiento oftalmológico estrecho durante 6 meses. Resultado Todos los pacientes presentaron una inflamación marcada del segmento anterior con edema corneal que se resolvió en todos los casos (entre 5 días y 3 meses). A los 6 meses de seguimiento se constató una diferencia significativa en el recuento endotelial corneal de dichos ojos al compararlo con el ojo contralateral (p=0,038), siendo<1000cels/mm2 en 3 casos. Tres pacientes (37,5%) presentaron un edema macular precoz, dejando como secuela permanente la disrupción de la capa elipsoidal a nivel subfoveal en uno de los casos. Uno de los pacientes desarrolló una neuropatía óptica con defecto pupilar aferente asociado. Conclusiones Aunque la inyección de cefuroxima en cámara anterior a dosis de 1mg/0,1ml ha demostrado disminuir la incidencia de endoftalmitis, su sobredosificación puede tener efectos oculares potencialmente perjudiciales tanto en el segmento anterior como en el posterior (AU)

RESUMO
OBJECTIVES: The goal of this study is to assess, by means of pharmacokinetic/pharmacodynamic (PK/PD) analysis using the Monte Carlo simulation, the adequacy of oral cephalosporins cefuroxime axetil, cefixime and cefditoren at different dosing regimens as switch therapy after intravenous cephalosporin treatment in uncomplicated acute pyelonephritis. METHODS: The methodology included: (i) dosing regimen selection and acquisition of pharmacokinetic data; (ii) microbiological data acquisition; and (iii) Monte Carlo simulation to estimate the PTA (probability of PK/PD target attainment) and CFR (cumulative fraction of response), as indicators of treatment success. RESULTS: At the current susceptibility breakpoints defined by EUCAST and CLSI for either cefuroxime axetil or cefixime, the probability of bactericidal target attainment is zero for the dosage regimens simulated. Considering the bactericidal target %fT>MIC>70%, the likelihood of the cefuroxime 500-mg q8h regimen or the cefixime 200-mg q12h regimen producing this exposure or achieving this target is only above 90% for organisms yielding MICs≤0.5mg/l and MICs≤0.25mg/l, respectively. Cefditoren pivoxil 400mg q12h provided probabilities of bactericidal target attainment of 80% or higher for MICs≤0.03mg/l, and ≤0.25mg/l if considering total instead of free drug concentrations. CONCLUSIONS: The results of the PK/PD target attainment analysis reveal that the likelihood of treatment success based upon the current breakpoints proposed by either EUCAST or CLSI is low. Of the three cephalosporins, cefixime 400mg q12h prove to be the best option in oral APN treatment, although this regimen is currently off label.

ABSTRACT PURPOSE: We examined the effect of intracameral administration of cefuroxime on oxidative stress and endothelial apoptosis in rat corneal tissue. METHODS: In total, 30 rats were divided into 3 groups of 10 rats each (intracameral administration of cefuroxime 0.1 mg/0.01 mL (cefuroxime group); intracameral administration of balanced salt solution 0.01 mL (control group); or absence of intracameral injection (sham group). Corneal endothelial apoptosis was assessed by immunohistochemical analysis using caspase-3 and caspase-8. Total oxidant status, total antioxidant status, oxidative stress index, and paraoxonase and arylesterase levels were examined in corneal endothelial tissue and serum. RESULTS: Paraoxonase levels in the serum were significantly different between the sham and cefuroxime groups (p=0.027). A significant difference was also observed in total oxidant status levels between the cefuroxime and balanced salt solution groups (p=0.023). In addition, there were significant differences in total antioxidant status levels in corneal tissue between the cefuroxime and sham groups (p<0.001) and between the cefuroxime and balanced salt solution groups (p<0.001). Furthermore, significant differences were also observed in oxidative stress index levels between the cefuroxime and balanced salt solution groups (p=0.001) and between the cefuroxime and sham groups (p=0.026). According to the immunohistochemical staining results, a significant association with caspase-3 activity existed between the cefuroxime and balanced salt solution groups (p=0.007), while no significant difference was found with caspase-8 activity (p=0.541). Caspase-3 activity exhibited a significant relationship between the sham and balanced salt solution groups (p=0.018), but no relationship was found with caspase-8 activity (p=0.623). CONCLUSION: Immunohistochemical examination revealed that intracameral cefuroxime increased apoptosis when compared to the sham and balanced salt solution groups. Moreover, intracameral cefuroxime increased oxidative stress in the cornea and simultaneously induced apoptosis.
RESUMO OBJETIVO: Examinamos o efeito da administração intracameral da cefuroxima sobre o estresse oxidativo e a apoptose endotelial no tecido corneano de ratos. MÉTODOS: No total, 30 ratos foram divididos em 3 grupos de 10 ratos cada (administração intracameral de cefuroxima 0,1 mg/0,01 mL (grupo cefuroxima), administração intracameral de solução salina balanceada 0,01 mL (grupo controle) ou ausência de injeção intracameral (grupo sham)). A apoptose endotelial da córnea foi avaliada por análise imuno-histoquimica usando caspase-3 e -8. O status oxidante total, o status antioxidante total, o índice de estresse oxidativo e os níveis de a paraoxonase e arilesterase foram investigados no tecido endotelial da córnea e no soro. RESULTADOS: Os níveis de paraoxonase no soro foram significativamente diferentes entre os grupos sham e cefuroxima (p=0,027). Foi também observada uma diferença significativa nos níveis de estado oxidante total entre os grupos cefuroxima e solução salina balanceada (p=0,023). Além disso, houve diferenças significativas nos níveis de status antioxidante total no tecido da córnea entre os grupos cefuroxima e sham (p<0,001) e entre os grupos cefuroxima e solução salina balanceada (p<0,001). Diferenças significativas também foram observadas nos níveis do índice de estresse oxidativo entre os grupos cefuroxima e solução salina balanceada (p=0,001) e entre os grupos cefuroxima e sham (p=0,026). De acordo com os resultados de coloração imuno-histoquimica, houve associação significativa com a atividade da caspase-3 entre os grupos cefuroxima e solução salina balanceada (p=0,007), enquanto não houve diferença significativa com a atividade da caspase-8 (p=0,541). A atividade da caspase-3 exibiu uma relação significativa entre os grupos sham e solução salina balanceada (p=0,018), mas nenhuma relação foi encontrada com a atividade da caspase-8 (p=0,623). CONCLUSÃO: O exame imuno-histoquímico revelou que a cefuroxima intracameral aumentou a apoptose quando comparada com os grupos sham e solução salina balanceada. Além disso, a cefuroxima intracameral aumentou o estresse oxidativo na córnea e induziu simultaneamente a apoptose.

Materiales y métodos: Estudio retrospectivo, observacional y transversal efectuado en pacientes que finalizaron el embarazo en la Clínica Jesús del Norte del distrito de Independencia de Lima, Perú, entre enero de 2016 y diciembre del 2017. Criterio de inclusión: pacientes con al menos seis citas médicas de control prenatal en la clínica. Se obtuvo el resultado de los urocultivos y el de resistencia a los antibióticos. Se buscaron medidas de tendencia central como promedios, desviación estándar y frecuencias. Resultados: Se registraron 1455 pacientes que cumplieron con el criterio de inclusión; de éstas 108 (7.4%) tuvieron infección de la vía urinaria con urocultivo positivo. El microorganismo aislado con más frecuencia fue Escherichia coli en 70 (63.6%) casos, con resistencia a ampicilina (60.8%), ciprofloxacina (34.7%) y norfloxacina (34.7%), y sensibilidad a amikacina, nitrofurantoína y cefuroxima. En 13 (11.8%) pacientes también se identificó Escherichia coli y enterobacterias productoras de betalactamasas de espectro extendido resistentes a cefalosporinas. Conclusión: La prevalencia de infección de la vía urinaria estuvo dentro del valor de referencia expresado en los reportes internacionales (7.4%). Los microorganismos aislados con mayor frecuencia fueron E. coli y E. coli productora de betalactamasas de espectro extendido.
Abstract Objective: To describe the prevalence of urinary tract infections (UTI) and their microbiological profile in pregnant women attended in a private clinic of level II-2 of Lima, Peru. Materials and methods: An analytical cross-sectional observational study was conducted, in women they had their delivery in a private clinic during January 2016 to December 2017. Inclusion criteria were those who had at least 06 prenatal care. Results of urocultures and their respective antibiotic resistance were obtained. In the statistical analysis, central tendency measures such as averages, standard deviation and frequencies were found. Results: 1455 met the selection criteria. We found 108 patients (7.4%) with UTI with a positive urine culture. The 70 cases (63.6%) were Escherichia coli resistant to antibiotics such as: ampicillin (57.6%), ciprofloxacin (30.7%) and norfloxacin (30.7%), and sensitive to: amikacin, nitrofurantoin and cefuroxime. However, was is found that 13 (11.8%) had Escherichia coli BLEE resistant to cephalosporins. Conclusion: The prevalence of urinary infection was within what was expected in relation to international reports. The most commonly isolated uropathogen was Escherichia coli, followed by Escherichia coli BLEE.
RESUMO
Abstract We report a case of perianesthetic refractory anaphylactic shock with cefuroxime in a patient with history of penicillin allergy on regular therapy with atenolol, losartan, prazosin and nicardipine. Severe anaphylactic shock was only transiently responsive to 10 mL of (1:10,000) epinephrine and needed norepinephrine and dopamine infusion. Supportive therapy with vasopressors and inotropes along with mechanical ventilation for the next 24 hours resulted in complete recovery. She was successfully operated upon 2 weeks later with the same anesthetic drugs but intravenous ciprofloxacin as the alternative antibiotic for perioperative prophylaxis.
Resumo Relatamos um caso de choque anafilático refratário no período perianestésico com cefuroxima em paciente com história de alergia à penicilina em terapia regular com atenolol, losartan, prazosina e nicardipine. O choque anafilático grave foi apenas transitoriamente responsivo a 10 mL de epinefrina (1:10000) e precisou de infusão de norepinefrina e dopamina. A terapia de apoio com vasopressores e inotrópicos, juntamente com ventilação mecânica por 24 horas, resultou em recuperação completa. A paciente foi operada com sucesso duas semanas mais tarde, com os mesmos agentes anestésicos, mas com ciprofloxacina intravenosa como antibiótico opcional para a profilaxia perioperatória.

OBJECTIVE: To describe the proportion of patients allergic to ß-lactam antibiotics and the prevalence of preoperative conjunctival bacteria among those undergoing cataract surgery in our area. METHOD: Retrospective cross-sectional study of prevalence of ß-lactam allergic patients consecutively scheduled for cataract surgery from 11 July 2005 to November 2012. For studying the prevalence of conjunctival bacteria and clinical characteristics in the patients' preoperative examination, those under 18 years and those with cataract surgery combined with other eye surgeries were excluded. Data from the first preoperative examination of the remaining patients were selected. Clinical data were extracted from the database generated in the evaluation made for anesthetic purposes, and the microbiological data from the laboratory database. Both bases were linked through a patient history code. A comparison was made between the prevalence of conjunctival bacteria and clinical characteristics in allergic and non-allergic patients. RESULTS: From 12,409 adults selected for the bacteriological study, 862 (6.96%) were allergic to ß-lactams, their mean age (74.45 years) was higher than that of the non-allergic (P=.005). The proportion of women (71.4%) in the allergic patient group was much higher than that of men. The prevalence of pathogenic bacteria (especially Bacillus spp and Pseudomonas aeruginosa), lung disease and heart failure, was higher in allergic patients. CONCLUSIONS: The prevalence of allergy to ß-lactams in this study is within the range described in other populations. The higher prevalence of pathogenic bacteria and the predominance of women in those allergic to ß-lactams are useful data to guide their surgical prophylaxis.

Cefuroxime axetil immediate release tablets were formulated by direct compression method with different percentages of sodium lauryl sulphate (SLS) such as 0.5, 1.0, 1.5 and also without SLS. Resulting batches of tablets were evaluated by both pharmacopeial and non-pharmacopeial methods to ascertain the physico-mechanical properties. Dissolution test were carried out in different medium like 0.07 M HCl, distilled water, 0.1M HCl of pH 1.2 and phosphate buffers at pH 4.5 and 6.8 to observe the drug release against the respective concentration of SLS used. Later, test formulations were compared by f1 (dissimilarity) and f2 (similarity) factors using a reference brand of cefuroxime axetil. Significant differences (p<0.05) in dissolution rate were recorded with the change in concentration of SLS in different media. Test formulation T3 containing 1% SLS was found to be best optimized formulation based on assay, disintegration, dissolution and similarity and dissimilarity factors.
Formularam-se comprimidos de liberação imediata à base de cefuroxima axetil, pelo método de compressão direta, com diferentes percentagens de lauril sulfato de sódio (LSS), tais como 0,5, 1,0, 1,5, e também sem SLS. Os lotes resultantes dos comprimidos foram avaliados por ambos os métodos da farmacopeia e não farmacopeicos para determinar as propriedades físico-mecânicas. O teste de dissolução foi realizado em meios diferentes, como HCl 0,07 M, água destilada, HCl 0,1 M com pH 1,2 e os tampões fosfato (pH 4,5 e 6,8) para observar a liberação do fármaco contra a correspondente concentração de LSS utilizado. Em seguida, as formulações de teste foram comparadas por fatores f1 (dissimilaridade) e f2 (similaridade), utilizando uma marca de referência de cefuroxima axetil. Diferenças significativas (p<0,05) na taxa de dissolução foram registradas com a mudança na concentração de LSS em diferentes meios de dissolução. A formulação T3 contendo LSS a 1% foi considerada a melhor formulação otimizada com base nos ensaios de desintegração, dissolução e fatores de semelhança e dissimilaridade.
