Aislamiento e identificación de Candida albicans de la cavidad oral, mediante el uso del Agar cromogénico en la población interna del Asilo San Antonio y Casa de la Misericordia de la ciudad de San Miguel

La investigación se realizó en la población con los adultos mayores del Asilo San Antonio y Casa de la Misericordia de la Ciudad de San Miguel, en el período de Junio a Julio de 2015. El Objetivo de la investigación fue aislar e identificar Candida albicans en muestras de la cavidad oral, mediante el uso del agar cromogénico de la población interna del Asilo San Antonio y Casa de la Misericordia de la Ciudad de San Miguel. El diseño metodológico es de tipo descriptivo, prospectivo, transversal, y de laboratorio, para el cual se tomaron 61 muestras de la cavidad oral de los internos en el Asilo San Antonio y Casa de la Misericordia de la Ciudad de San Miguel a través de un hisopado bucal con el que se realizó un examen directo al fresco con Solución Salina estéril al 0.85% en la búsqueda de levaduras; posteriormente se procedió a sembrar en el agar cromogénico Brilliance Candida, para observar el crecimiento de colonias verdes, las cuales indican la presencia de Candida albicans, como agente causal de Candidiasis oral. Resultados: De las 61 muestras procesadas a 26 se les aisló e identificó Candida albicas con un porcentaje de 42.7%. De los 22 adultos mayores que presentaban lesiones sugestivas a candidiasis oral a 20 se les aisló e identificó Candida albicans de los cuales 15 (88.2%) pertenecen al Asilo San Antonio y 5 (100%) pertenecen a la Casa de la Misericordia. De los 10 adultos mayores que reportaron que no practican el aseo bucal se les aisló e identificó Candida albicans a 3 (33.3%) de ellos que se encuentran en el Asilo San Antonio. A 5 internos que reportaron practicar algunas veces el aseo bucal también se les aisló e identificó Candida albicans, 4 (44.4%) pertenecen al Asilo San Antonio y 1 (50%) a la Casa de la Misericordia. De los 18 adultos mayores que usan prótesis dentales a 7 (53.8%) se les aisló e identificó Candida albicans en el Asilo San Antonio y en la Casa de la Misericordia a 5 (100%) internos se les aisló e identificó Candida albicans. De 35 adultos mayores que reportaron que usan antibiótico a 14 (46.7%) que se encuentran en el Asilo San Antonio se les aisló e identificó Candida albicans. Con respecto Casa de la Misericordia de los 5 (100%) que reportaron que usan antibiótico no se les aisló Candida albicans. En 16 (26.2%) muestras no se observó crecimiento de ninguna especie de Candida. Conclusiones: Se estudió a la población interna del Asilo San Antonio y Casa de La Misericordia debido a que los adultos mayores son vulnerables a las infecciones por hongos oportunistas ya que su sistema inmunológico se encuentra disminuido unido a una serie de factores predisponentes, como el uso de prótesis dentales, antibióticos, mal higiene bucal y diabetes. Mediante el uso del agar Brilliance Candida se logró diferenciar otras especies del género Candida como Candida tropicalis 26.2%, Candida krusei 3.3% y Candida glabrata 1.6%. De acuerdo a estos resultados y las conclusiones de la investigación se plantean algunas recomendaciones orientadas principalmente al personal de salud para brindar apoyo a este tipo de estudios.

Prevalence of surgical wound infection after surgery for breast cancer: systematic review

One of the known risk factors for abuse and neglect of the elderly is the decrease in functionat capacity, contributíng to self care dependency of instrumental actívities of daily living and basic activities of daily Itving (OMS, 2015). Methods: Cross-sectional study with non probabilistíc sample of 333 elderly, performed in a hospital, homes and day centers for the elderly. The data collectíon protocol tncluded socio-demographic data, Questíons to elicit Elder Abuse (Carney, Kahan B Paris, 2003 adap. By Ferreira Alves & Sousa, 2005), scale of instrumental actívi - ties of daily living Lawton and Brody and Katz index to assess the levei of independence in actívities of daily living. Objectives: To evaluate the assodation between abuse and neglect in the elderly, instrumental actívitíes of daily living and levei of independence in actívitíes of daily living. Results: Emotional abuse is signifícantty correlated with the levei of independence in activities of daity Uving (p = 0. 000), older peopie with less independence tend to have higher leveis of emotional abuse. The total abuse is signtficantly correlated with the leveis of independence in activittes of daily living (p = 0. 002), less independent elderty tend to suffer greater abuse and neglect. There were no statistically significant associations between abuse and neglect and instrumental activities of daily l1v1ng. Conclusions: The less independent elderly are more vulnerable to situatíons of abuse and neglect, being more exposed to emotional abuse. These results point to the need for health professionals/ nurses develop prevention interventions, including strategies to support carers and early screentng tn less independent elderly. Keywords: Elder abuse. Negligence. Nursing care. Frail elderly. PREVALENCE OF SURGICAL WOUND INFECTION AFTER SURGERY FOR BREAST CÂNCER: SYSTEMATIC REVIEW C. Amaral3, C. Teixeira"'1', F. Sousa'', C.

Breast surgery is the usual treatment for this pathology, however such procedure can be complicated by the infection of surgical site. Objectives: To know the prevalence and determtnants of surgtcal wound infection after breast surgery. Methods: We conducted a systematic review by searching of the Web of Sdence electronic database for articles published over the last s1x years 1n developed countries. Over three hundred dtatíons were obtained and after excludtng citations with reasons, fíve artícles met our inclusion criteria and were included in the present review. Results: Prevalence of surgical wound infection varied across studies between 0. 1% and 12. 5%. Bilateral mastectomy is assodated with higher prevalence of wound infectíon than unilateral mastectomy (3. 6% vs 3, 3%), lumpectomy with immediate breast reconstruction (IBR) is related with higher frequency of wound infectíon than surgery with no IBR (0, 5% vs 0, 1%), also, mastectomy with IBR is associated with higher prevalence of wound infectíon than mastectomy wtth no IBR (1, 5% vs 0, 3%) and breast surgery followed by axiltary lymph nade dissectíon is related with higher prevalence of wound infection than surgical procedures wtth no axillary lymph node dissection (2, 82% vs 1, 66%). Conclusions: Nurses that provide post-operatíve care to women after breast surgery should be aware about risk of wound tnfectíon, partícularly after more invasive procedures.

First description of Candida nivariensis in Brazil: antifungal susceptibility profile and potential virulence attributes

This study evaluated the antifungal susceptibility profile and the production of potential virulence attributes in a clinical strain of Candida nivariensis for the first time in Brazil, as identified by sequencing the internal transcribed spacer (ITS)1-5.8S-ITS2 region and D1/D2 domains of the 28S of the rDNA. For comparative purposes, tests were also performed with reference strains. All strains presented low planktonic minimal inhibitory concentrations (PMICs) to amphotericin B (AMB), caspofungin (CAS), and voriconazole. However, our strain showed elevated planktonic MICs to posaconazole (POS) and itraconazole, in addition to fluconazole resistance. Adherence to inert surfaces was conducted onto glass and polystyrene. The biofilm formation and antifungal susceptibility on biofilmgrowing cells were evaluated by crystal violet staining and a XTT reduction assay. All fungal strains were able to bind both tested surfaces and form biofilm, with a binding preference to polystyrene (p < 0.001). AMB promoted significant reductions (≈50%) in biofilm production by our C. nivariensis strain using both methodologies. This reduction was also observed for CAS and POS, but only in the XTT assay. All strains were excellent protease producers and moderate phytase producers, but lipases were not detected. This study reinforces the pathogenic potential of C. nivariensis and its possible resistance profile to the azolic drugs generally used for candidiasis management.

The identification and differentiation of the Candida parapsilosis complex species by polymerase chain reaction-restriction fragment length polymorphism of the internal transcribed spacer region of the rDNA

Currently, it is accepted that there are three species that were formerly grouped under Candida parapsilosis : C. parapsilosis sensu stricto, Candida orthopsilosis , and Candida metapsilosis . In fact, the antifungal susceptibility profiles and distinct virulence attributes demonstrate the differences in these nosocomial pathogens. An accurate, fast, and economical identification of fungal species has been the main goal in mycology. In the present study, we searched sequences that were available in the GenBank database in order to identify the complete sequence for the internal transcribed spacer (ITS)1-5.8S-ITS2 region, which is comprised of the forward and reverse primers ITS1 and ITS4. Subsequently, an in silico polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed to differentiate the C. parapsilosis complex species. Ninety-eight clinical isolates from patients with fungaemia were submitted for analysis, where 59 isolates were identified as C. parapsilosis sensu stricto, 37 were identified as C. orthopsilosis, and two were identified as C. metapsilosis. PCR-RFLP quickly and accurately identified C. parapsilosis complex species, making this method an alternative and routine identification system for use in clinical mycology laboratories.

Single-nucleotide polymorphism in two representative multidrug-resistant Mycobacterium bovis isolates collected from patients in a Spanish hospital harboring a human infection outbreak

Mycobacterium bovis is the etiological agent of tuberculosis in domestic and wild animals. Its involvement as a human pathogen has been highlighted again with the recent descriptions of transmission through dairy products (18), reactivation or primary infection in human immunodeficiency virus-infected patients (5), and association with meat industry workers, animal keepers, or hunters (3). Strains resistant to antituberculous drugs (M. bovis is naturally resistant to pyrazinamide) pose an additional risk (2). Several studies have demonstrated that mutations in target genes are associated with resistance to antituberculous drugs (4, 7, 10, 11, 16). However, most of them have been developed in Mycobacterium tuberculosis strains and limited data are available regarding M. bovis isolates. The aim of this study was to characterize by sequencing the main genes involved in antibiotic resistance in two multidrug-resistant (MDR) M. bovis isolates in a human outbreak detected in a hospital in Madrid that subsequently spread to several countries (5, 6, 15). The isolates were resistant to 11 drugs, but only their rpoB and katG genes have been analyzed so far (1, 14). We studied the first (93/R1) and last (95/R4) M. bovis isolates of this nosocomial outbreak, characterized by spoligotyping as SB0426 (hexacode 63-5F-5E-7F-FF-60 in the database at www.mbovis.org) (1, 13). Several genes involved in resistance to isoniazid (katG, ahpC, inhA, and the oxyR-ahpC intergenic region), rifampin (rpoB), streptomycin (rrs, rpsL), ethambutol (embB), and quinolones (gyrA) were studied. These genes, or fragments of genes, were amplified and sequenced as previously described (12). The sequence analysis revealed polymorphisms in five (ahpC, rpoB, rpsL, embB, and gyrA) out of nine analyzed genes (Table 1). Nucleotide substitutions in four genes cause a change in the encoded amino acid. Two additional synonymous mutations in ahpC and rpsL differentiated the first and last isolates from the outbreak.

Estudio proteómico de las vesículas extracelulares y del secretoma de "Candida albicans" y análisis funcional de proteínas de superficie celular

Candida albicans es un importante patógeno oportunista en humanos, que puede causar distintos tipos de infecciones, desde micosis superficiales hasta sistémicas. La candidiasis invasiva es una enfermedad que puede causar mortalidad en pacientes inmunocomprometidos. Para causar daño en el hospedador, C. albicans cuenta con una serie de factores de virulencia. Entre ellos destaca la capacidad de cambiar su forma de crecimiento de levadura a hifa. La superficie celular es la estructura más externa de la célula y el punto de contacto entre el hongo y el hospedador. Las proteínas de superficie tienen un papel importante en la integridad estructural de la célula y en la adherencia e invasión de células del hospedador. Una de las proteínas localizadas en la superficie celular es Ecm33, una proteína de pared celular con anclaje glicosilfosfatidilinositol (GPI). La deleción de esta proteína afecta a la morfología tanto de levaduras como de hifas, dando como resultado células con la pared celular alterada y virulencia reducida tanto en condiciones in vitro como in vivo. El secretoma o las proteínas secretadas por C. albicans son también relevantes en la interacción patógeno-hospedador. C. albicans secreta muchas proteínas importantes relacionadas con diferentes procesos, entre los que se incluyen la formación de biofilms, la adquisición de nutrientes y el mantenimiento de la integridad de la pared celular. Muchas de estas proteínas secretadas, como las pertenecientes a las familias de aspartil proteasas (Sap) y la familia de fosfolipasas B (Plb), también han sido detectadas en la pared celular, ya que deben pasar a través de ella en su tránsito hacia el medio extracelular. Estas proteínas tienen un péptido señal en el extremo N-terminal que es el responsable de dirigirlas a la ruta clásica de secreción. Sin embargo, cerca de un tercio de las proteínas identificadas en el medio extracelular de C. albicans no poseen dicho péptido señal en su secuencia...

Perfil epidemiológico y análisis de la formulación antibiótica en pacientes con infección urinaria nosocomial en la Fundación Cardioinfantil en el año 2014

Introducción: La IVU es muy frecuenten en la (FCI - IC), Alrededor el 60% de los pacientes con diagnóstico de IVU nosocomial corresponden a gérmenes resistente, Desde el año 2010 el CLSI disminuyó los puntos de corte de sensibilidad en las enterobacteriaceae y removió la necesidad de tamizaje y confirmación de (BLEE), en el presente trabajo se pretende determinar el perfil epidemiológico de la formulación antibiótica en pacientes con IVU nosocomial. Diseño: Se realizó un estudio observacional analítico de corte transversal. Métodos: Se realizó un análisis univariado, bivariado y multivariado. El análisis bivariado y multivariado se realizó para determinar la medida de asociación teniendo en cuenta la formulación de Carbapenemico la variable dependiente, evaluándose mediante chi cuadrado. Resultados: Se revisaron 131 urocultivos, se incluyeron 116. Los aislamientos microbiológicos más frecuentemente encontrados fueron E. Coli y K. Pneumoniae, el 43.4% de los aislamientos, presentaron expresión de BLEE, 90% de los aislamientos fueron sensibles a Cefepime. La mayoría de los modelos obtenidos mostraron una fuerte asociación entre el reporte de BLEE en antibiograma con la formulación de carbapenémicos como terapia final OR 33,12 IC 95% (2,90 – 337,4). Conclusión: La epidemiologia de la IVU nosocomial en la FCI-IC no difiere de las referencias internacionales, no hay adherencia a las guías de manejo intrahospitalario y el reporte de la palabra BLEE en el antibiograma predice la formulación de antibiótico carbapenémico por el médico que lee el urocultivo

Infección por virus sincitial respiratorio y su relación con valores de IGG en niños críticos

Antecedente: La infección por el virus sincitial respiratorio (VSR) representa una elevada morbimortalidad, y en algunos casos necesidad de manejo en unidades de cuidado intensivo pediátrico (UCIP). La respuesta inmunológica influye de manera directa en la expresión de la severidad y pronóstico de los pacientes con infección respiratoria. Metodología: Estudio de una cohorte retrospectiva de pacientes con infección respiratoria grave secundaria a VSR, sin historia de inmunodeficiencia, atendidos en la UCIP del Hospital Universitario Clínica San Rafael. Se realizó análisis descriptivoglobaly de acuerdo a la categorización de las prueba de IgG. Resultados: De 188 pacientes que ingresaron a la UCIP, 13% presentaron infección por VSR (24), con una edad promedio de 7,3 (DE=3,6) meses. Pertenecían al sexo masculino79,83%. Se encontró que 12,5% tenían un valor de IgGbajo para su edad, 58,33% tenían valores en límite inferior y el 29,17% dentro de rangos normales para su edad. En los pacientes con IgG baja, fue mayor la presentación de choque séptico que no responde a líquidos (100 vs 92 vs 86%), la mediana de días de ventilación mecánica fue mayor (8 vs 6 vs 5 respectivamente), así como la mortalidad (67 vs 7,1 vs 0%). Conclusión: Nuestra serie encontró que aquellos pacientes con niveles bajos o valores en el límite inferior de IgG sérica tuvieron mayor compromiso sistémico, mayor duración de ventilación mecánica y mayor mortalidad. Se necesitan estudios prospectivos que relaciones niveles bajos de IgG con severidad y pronostico en estos pacientes con infección grave por VSR.

Stewardship antibiotica neonatale: valutazione dell'esposizione antimicrobica nelle sospette early onset sepsis (EOS)

Background: Le early-onset sepsis (EOS) sono infezioni batteriche invasive definite dalla presenza di batteri nel sangue e/o nel liquor cefalorachidiano che esordiscono nelle prime 72 ore di vita e causano in epoca neonatale mortalità e morbilità importanti. Scopo: Determinare l’eccesso di trattamento antibiotico (Overtreatment index=OI) nei neonati di EG ≥34 settimane con sospetta sepsi ad esordio precoce. Metodi: Tutti i nati dal 1.01.2014 al 31.12.2018 di EG ≥34 settimane presso IRCCS Azienda Ospedaliero-Universitaria e l’Ospedale Maggiore di Bologna che hanno ricevuto terapia antibiotica endovenosa nelle prime 168 ore di vita nel sospetto di EOS. Sono stati identificati 2 gruppi: EOS provata (N=7) ed EOS sospetta (N=465). Risultati: L’incidenza di EOS è stata 0.22 su 1000 nati vivi, rispettivamente 0.12/1000 per Streptococcus agalactiae (GBS) e 0.06/1000 per Escherichia coli (E.coli). L’1.75% dei neonati ha ricevuto terapia antimicrobica empirica a largo spettro. L’OI è risultato 68. L’esposizione al trattamento antibiotico nella popolazione è stata di 85 giorni/1000 nati vivi. Tra i fattori di rischio materni, il tampone vagino-rettale (TVR) e l’urinocoltura positiva sono risultati associati al rischio di EOS provata (p=.017, p =.000). I valori di proteina C reattiva (PCR) al T0, T1 e T2 tra i due gruppi sono risultati significativi (p=.000). All’analisi multivariata è stata confermata la significatività delle variabili descritte. (TVR non noto OR=15.1, 95%CI 1.98-115.50, p =.009, urinocoltura positiva OR=30.1, 95%CI 3.6-252.1, p = .002, PCR T0 OR=1.6, 95% CI 1.29-2.07, p = .000.) Conclusioni: L’individuazione precoce di fattori di rischio e la valutazione degli indici di flogosi in neonati sintomatici può ridurre l’OI e la durata della terapia antibiotica in casi di sepsi non confermata. L’uso appropriato degli antibiotici in questa popolazione è particolarmente importante poichè riduce lo sviluppo di germi multiresistenti. Nelle Terapie Intensive Neonatali, i programmi di stewardship antimicrobica dovrebbero guidare la gestione delle sepsi.

Evaluation Of Different Treatment Methods Against Denture Stomatitis: A Randomized Clinical Study.

The aim of this clinical study was to determine the efficacy of Uncaria tomentosa (cat's claw) against denture stomatitis (DS). Fifty patients with DS were randomly assigned into 3 groups to receive 2% miconazole, placebo, or 2% U tomentosa gel. DS level was recorded immediately, after 1 week of treatment, and 1 week after treatment. The clinical effectiveness of each treatment was measured using Newton's criteria. Mycologic samples from palatal mucosa and prosthesis were obtained to determinate colony forming units per milliliter (CFU/mL) and fungal identification at each evaluation period. Candida species were identified with HiCrome Candida and API 20C AUX biochemical test. DS severity decreased in all groups (P < .05). A significant reduction in number of CFU/mL after 1 week (P < .05) was observed for all groups and remained after 14 days (P > .05). C albicans was the most prevalent microorganism before treatment, followed by C tropicalis, C glabrata, and C krusei, regardless of the group and time evaluated. U tomentosa gel had the same effect as 2% miconazole gel. U tomentosa gel is an effective topical adjuvant treatment for denture stomatitis.

Hypertrophic Adenoid Is A Major Infection Site Of Human Bocavirus 1.

Human bocavirus 1 (HBoV1) is associated with respiratory infections worldwide, mainly in children. Similar to other parvoviruses, it is believed that HBoV1 can persist for long periods of time in humans, probably through maintaining concatemers of the virus single-stranded DNA genome in the nuclei of infected cells. Recently, HBoV-1 was detected in high rates in adenoid and palatine tonsils samples from patients with chronic adenotonsillar diseases, but nothing is known about the virus replication levels in those tissues. A 3-year prospective hospital-based study was conducted to detect and quantify HBoV1 DNA and mRNAs in samples of the adenoids (AD), palatine tonsils (PT), nasopharyngeal secretions (NPS), and peripheral blood (PB) from patients undergoing tonsillectomy for tonsillar hypertrophy or recurrent tonsillitis. HBoV1 was detected in 25.3% of the AD samples, while the rates of detection in the PT, NPS, and PB samples were 7.2%, 10.5%, and 1.7%, respectively. The viral loads were higher in AD samples, and 27.3% of the patients with HBoV had mRNA detectable in this tissue. High viral loads and detectable mRNA in the AD were associated with HBoV1 detection in the other sample sites. The adenoids are an important site of HBoV1 replication and persistence in children with tonsillar hypertrophy. The adenoids contain high HBoV1 loads and are frequently positive for HBoV mRNA, and this is associated with the detection of HBoV1 in secretions.

Effects Of Therapeutic Approach On The Neonatal Evolution Of Very Low Birth Weight Infants With Patent Ductus Arteriosus.

To analyze the effects of treatment approach on the outcomes of newborns (birth weight [BW] < 1,000 g) with patent ductus arteriosus (PDA), from the Brazilian Neonatal Research Network (BNRN) on: death, bronchopulmonary dysplasia (BPD), severe intraventricular hemorrhage (IVH III/IV), retinopathy of prematurity requiring surgical (ROPsur), necrotizing enterocolitis requiring surgery (NECsur), and death/BPD. This was a multicentric, cohort study, retrospective data collection, including newborns (BW < 1000 g) with gestational age (GA) < 33 weeks and echocardiographic diagnosis of PDA, from 16 neonatal units of the BNRN from January 1, 2010 to Dec 31, 2011. Newborns who died or were transferred until the third day of life, and those with presence of congenital malformation or infection were excluded. Groups: G1 - conservative approach (without treatment), G2 - pharmacologic (indomethacin or ibuprofen), G3 - surgical ligation (independent of previous treatment). Factors analyzed: antenatal corticosteroid, cesarean section, BW, GA, 5 min. Apgar score < 4, male gender, Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE II), respiratory distress syndrome (RDS), late sepsis (LS), mechanical ventilation (MV), surfactant (< 2 h of life), and time of MV. death, O2 dependence at 36 weeks (BPD36wks), IVH III/IV, ROPsur, NECsur, and death/BPD36wks. Student's t-test, chi-squared test, or Fisher's exact test; Odds ratio (95% CI); logistic binary regression and backward stepwise multiple regression. Software: MedCalc (Medical Calculator) software, version 12.1.4.0. p-values < 0.05 were considered statistically significant. 1,097 newborns were selected and 494 newborns were included: G1 - 187 (37.8%), G2 - 205 (41.5%), and G3 - 102 (20.6%). The highest mortality was observed in G1 (51.3%) and the lowest in G3 (14.7%). The highest frequencies of BPD36wks (70.6%) and ROPsur were observed in G3 (23.5%). The lowest occurrence of death/BPD36wks occurred in G2 (58.0%). Pharmacological (OR 0.29; 95% CI: 0.14-0.62) and conservative (OR 0.34; 95% CI: 0.14-0.79) treatments were protective for the outcome death/BPD36wks. The conservative approach of PDA was associated to high mortality, the surgical approach to the occurrence of BPD36wks and ROPsur, and the pharmacological treatment was protective for the outcome death/BPD36wks.

Impact Of Pharmacist Interventions On Drug-related Problems And Laboratory Markers In Outpatients With Human Immunodeficiency Virus Infection.

Substantial complexity has been introduced into treatment regimens for patients with human immunodeficiency virus (HIV) infection. Many drug-related problems (DRPs) are detected in these patients, such as low adherence, therapeutic inefficacy, and safety issues. We evaluated the impact of pharmacist interventions on CD4+ T-lymphocyte count, HIV viral load, and DRPs in patients with HIV infection. In this 18-month prospective controlled study, 90 outpatients were selected by convenience sampling from the Hospital Dia-University of Campinas Teaching Hospital (Brazil). Forty-five patients comprised the pharmacist intervention group and 45 the control group; all patients had HIV infection with or without acquired immunodeficiency syndrome. Pharmaceutical appointments were conducted based on the Pharmacotherapy Workup method, although DRPs and pharmacist intervention classifications were modified for applicability to institutional service limitations and research requirements. Pharmacist interventions were performed immediately after detection of DRPs. The main outcome measures were DRPs, CD4+ T-lymphocyte count, and HIV viral load. After pharmacist intervention, DRPs decreased from 5.2 (95% confidence interval [CI] =4.1-6.2) to 4.2 (95% CI =3.3-5.1) per patient (P=0.043). A total of 122 pharmacist interventions were proposed, with an average of 2.7 interventions per patient. All the pharmacist interventions were accepted by physicians, and among patients, the interventions were well accepted during the appointments, but compliance with the interventions was not measured. A statistically significant increase in CD4+ T-lymphocyte count in the intervention group was found (260.7 cells/mm(3) [95% CI =175.8-345.6] to 312.0 cells/mm(3) [95% CI =23.5-40.6], P=0.015), which was not observed in the control group. There was no statistical difference between the groups regarding HIV viral load. This study suggests that pharmacist interventions in patients with HIV infection can cause an increase in CD4+ T-lymphocyte counts and a decrease in DRPs, demonstrating the importance of an optimal pharmaceutical care plan.

Urinary Tract Infection In Renal Transplant Recipients: Incidence, Risk Factors, And Impact On Graft Function.

Urinary tract infection (UTI) is the most common infection posttransplant. However, the risk factors for and the impact of UTIs remain controversial. The aim of this study was to identify the incidence of posttransplant UTIs in a series of renal transplant recipients from deceased donors. Secondary objectives were to identify: (1) the most frequent infectious agents; (2) risk factors related to donor; (3) risk factors related to recipients; and (4) impact of UTI on graft function. This was a retrospective analysis of medical records from renal transplant patients from January to December 2010. Local ethics committee approved the protocol. The incidence of UTI in this series was 34.2%. Risk factors for UTI were older age, (independent of gender), biopsy-proven acute rejection episodes, and kidneys from deceased donors (United Network for Organ Sharing criteria). For female patients, the number of pretransplant pregnancies was an additional risk factor. Recurrent UTI was observed in 44% of patients from the UTI group. The most common infectious agents were Escherichia coli and Klebsiella pneumoniae, for both isolated and recurrent UTI. No difference in renal graft function or immunosuppressive therapy was observed between groups after the 1-year follow-up. In this series, older age, previous pregnancy, kidneys from expanded criteria donors, and biopsy-proven acute rejection episodes were risk factors for posttransplant UTI. Recurrence of UTI was observed in 44%, with no negative impact on graft function or survival.
