Factores de riesgo asociados a mala adherencia en adolescentes trasplantados hepáticos en transición / Risk factors associated with poor adherence in adolescent liver transplant recipients in transition

Cada vez más pacientes trasplantados hepáticos durante la edad pediátrica alcanzan la adultez debido al aumento en las tasas de sobrevida a largo plazo, por lo que requieren continuar su atención en un centro de adultos. Este pasaje entre centros se asocia con peores resultados clínicos y mayor mala adherencia, debido al momento de vulnerabilidad que representa este momento en la atención médica y por el mismo momento vital atravesado por el paciente adolescente. La mayoría de los centros de trasplantes establecieron programas de transición para mejorar estos resultados. Para que estos programas sean efectivos, deben conocerse las barreras y los facilitadores de adherencia tanto en el paciente como en su entorno. El objetivo de este trabajo es reconocer estos factores de riesgo y su relación con mala adherencia y resultados clínicos, y realizar un seguimiento a corto plazo de los pacientes transferidos a un centro de atención de adultos. Para esto, se realizó una encuesta pre y post derivación a una cohorte de pacientes adolescentes del Hospital Garrahan. Para medir mala adherencia se utilizaron métodos objetivos y subjetivos, cada uno de los cuales correlacionó con distintos factores de riesgo, como presencia de violencia, consumo de sustancias y déficit educativo. Como conclusión, medir la mala adherencia es complejo debido a que su origen es multifactorial. Al parecer, combinar cuestionarios validados con entrevistas no estructuradas es la estrategia más efectiva para detectar mala adherencia en la consulta médica. Luego, las variables psicosociales están cobrando cada vez más relevancia y deben ser consideradas en los programas de transición de los servicios de trasplante si se quiere lograr un seguimiento a largo plazo exitoso (AU)

An increasing number of pediatric liver transplant patients reach adulthood due to the increase in long-term survival rates, and therefore require continued care in an adult center. This transition between centers is associated with worse clinical outcomes and poorer adherence, due to the vulnerability that this moment in medical care represents and the same vital moment that the adolescent patient goes through. Most transplant centers have established Transition Programs to improve these outcomes. For these programs to be effective, the barriers and facilitators of adherence in both the patient and their environment should be known. The aim of this study was to identify these risk factors and their relationship with poor adherence and clinical outcomes, and to perform a short-term follow-up of patients transferred to an adult care center. For this purpose, a pre- and post-referral survey was conducted on a cohort of adolescent patients from the Garrahan Hospital. Objective and subjective methods were used to measure poor adherence, each of which correlated with different risk factors, such as the presence of violence, substance use, and educational deficits. In conclusion, measuring poor adherence is complex because its origin is multifactorial. Combining validated questionnaires with unstructured interviews seems to be the most effective strategy for detecting poor adherence in the medical consultation. Therefore, psychosocial variables are becoming increasingly relevant and should be considered in the Transition Programs of transplantation services if a successful longterm follow-up is to be achieved (AU)

Comparison of palonosetron and ondansetron in preventing postoperative nausea and vomiting in renal transplantation recipients: a randomized clinical trial

Abstract Background: End-stage renal diseases patients have a high risk of postoperative nausea and vomiting (PONV), which is multifactorial and need acute attention after renal transplantation for a successful outcome in term of an uneventful postoperative period. The study was done to compare the efficacy of palonosetron and ondansetron in preventing early and late-onset PONV in live donor renal transplantation recipients (LDRT). Methods: The prospective randomized double-blinded study was done on 112 consecutive patients planned for live donor renal transplantation. Patients of both sexes in the age group of 18-60 years were randomly divided into two groups: Group O (Ondansetron) and Group P (Palonosetron) with 56 patients in each group by computer-generated randomization. The study drug was administered intravenously (IV) slowly over 30 seconds, one hour before extubation. Postoperatively, the patients were accessed for PONV at 6, 24, and 72 hours using the Visual Analogue Scale (VAS) nausea score and PONV intensity scale. Results: The incidence of PONV in the study was found to be 30.35%. There was significant difference in incidence of PONV between Group P and Group O at 6 hours (12.5% vs. 32.1%, p = 0.013) and 72 hours (1.8% vs. 33.9%, p < 0.001), but insignificant difference at 24 hours (1.8% vs. 10.7%, p = 0.113). VAS-nausea score was significantly lower in Group P as compared to Group O at a time point of 24 hours (45.54 ± 12.64 vs. 51.96 ± 14.70, p = 0.015) and 72 hours (39.11 ± 10.32 vs. 45.7 ± 15.12, p = 0.015). Conclusion: Palonosetron is clinically superior to ondansetron in preventing early and delayed onset postoperative nausea and vomiting in live-related renal transplant recipients.

Use of sirolimus as an adjuvant therapy for kidney transplant recipients with high-risk cutaneous squamous cell carcinomas: a prospective non-randomized controlled study / Uso do sirolimo como terapia adjuvante para receptores de transplante renal com carcinoma espinocelular cutâneo de alto risco: um estudo prospectivo controlado não randomizado

ABSTRACT Introduction: Previous research demonstrated benefits of late conversion to mTOR inhibitors against cutaneous squamous cell carcinomas (cSCC) in kidney transplant recipients (KTR), despite of poor tolerability. This study investigated whether stepwise conversion to sirolimus monotherapy without an attack dose modified the course of disease with improved tolerability. Methods: This prospective exploratory study included non-sensitized KTR with more than 12-months post-transplant, on continuous use of calcineurin inhibitors (CNI)-based therapy, and with poor-prognosis cSCC lesions. Incidence densities of high-risk cSCC over 3-years after conversion to sirolimus-monotherapy were compared to a non-randomized group with high-risk cSCC but unsuitable/not willing for conversion. Results: Forty-four patients were included (83% male, mean age 60 ± 9.7years, 62% with skin type II, mean time after transplantation 9 ± 5.7years). There were 25 patients converted to SRL and 19 individuals kept on CNI. There was a tendency of decreasing density of incidence of all cSCC in the SRL group and increasing in the CNI group (1.49 to 1.00 lesions/patient-year and 1.74 to 2.08 lesions/patient-year, p = 0.141). The density incidence of moderately differentiated decreased significantly in the SRL group while increasing significantly in the CNI group (0.31 to 0.11 lesions/patient-year and 0.25 to 0.62 lesions/patient-year, p = 0.001). In the SRL group, there were no sirolimus discontinuations, no acute rejection episodes, and no de novo DSA formation. Renal function remained stable. Conclusions: This study suggests that sirolimus monotherapy may be useful as adjuvant therapy of high-risk cSCC in kidney transplant recipients. The conversion strategy used was well tolerated and safe regarding key mid-term transplant outcomes.

RESUMO Introdução: Pesquisas anteriores demonstraram benefícios da conversão tardia para inibidores de mTOR contra carcinomas espinocelulares cutâneos (CECs) em receptores de transplante renal (RTR), apesar da baixa tolerabilidade. Este estudo investigou se a conversão gradual para monoterapia com sirolimo sem dose de ataque modificou o curso da doença com melhor tolerabilidade. Métodos: Esse estudo prospectivo exploratório incluiu RTR não sensibilizados com mais de 12 meses pós-transplante, uso contínuo de terapia imunossupressora baseado em inibidor de calcineurina (CNI) associado a micofenolato de sódio ou azatioprina, com lesões de CECs de mau prognóstico. Comparou-se densidades de incidência de CECs de alto risco durante 3 anos após conversão para monoterapia com sirolimo à um grupo não randomizado com CECs classificados conforme os mesmos critérios de gravidade do grupo sirolimo, mas inadequado/não disposto à conversão. Resultados: Foram incluídos 44 pacientes (83% homens, idade média 60 ± 9,7 anos, 62% com fototipo de pele II, tempo médio pós-transplante 9 ± 5,7 anos). 25 pacientes foram convertidos para SRL e 19 indivíduos mantidos em CNI. Foi observado tendência de diminuição da densidade de incidência de todos CECs no grupo SRL e de aumento no grupo CNI (1,49 a 1,00 lesões/paciente-ano; 1,74 a 2,08 lesões/paciente-ano; p = 0,141). A densidade de incidência de lesões moderadamente diferenciadas diminuiu significativamente no grupo SRL enquanto aumentou significativamente no grupo CNI (0,31 a 0,11 lesões/paciente-ano; 0,25 a 0,62 lesões/paciente-ano; p = 0,001). No grupo SRL não houve descontinuação do sirolimo, nenhum episódio de rejeição aguda e nenhuma formação de DSA de novo. Função renal permaneceu estável. Conclusões: Esse estudo sugere que a monoterapia com sirolimo pode ser útil como terapia adjuvante de CECs de alto risco em RTR. A estratégia de conversão usada foi bem tolerada e segura em relação aos principais desfechos do transplante a médio prazo.

Objective To gain insights into the supportive care needs of liver transplant recipients,in order to provide references for the formulation of effective and targeted intervention strategies.Methods Phenomenological research method was employed to conduct semi-structural in-depth interviews with 16 liver transplant recipients in the liver transplant center of a tertiary hospital in Shanghai from November 2021 to April 2022.Colaizzi 7-step analysis method and Nvivo software were used to analyze and extract the themes.Results 5 themes were extracted,including symptom management needs,longing for the perception and avoidance of recurrence risk,disease information management needs,emotional and psychological support and the return to social roles.Conclusion The physical distress and burden of liver transplantation recipients coexist.Although the initiative to seek medical treatment is high,the perception level of disease recurrence risk is not high.In order to meet the needs of liver transplant recipients and improve their quality of life,it is necessary to strengthen the health education of disease symptom management and related risk factors,pay attention to psychological counseling and strengthen social support,and provide targeted treatment care.

Health-related quality of life following lung transplantation for cystic fibrosis: A systematic review

Abstract Background: Lung transplantation represents the definite treatment for CF patients with advanced-stage pulmonary disease. Recent major developments in the treatment of CF indicate the need for an evaluation of lung transplantation as the current best practice in end-stage disease. This systematic review was performed to evaluate the impact of lung transplantation on health-related quality of life in patients with CF. Methods: PubMed was searched for studies matching the eligibility criteria between January 2000 and January 2022. OVID (MEDLINE), Google Scholar, and EBSCOhost (EMBASE) as well as bibliographies of included studies were also reviewed. Applying predetermined eligibility criteria, the included studies were selected. Predetermined forms were used to conduct a quality appraisal and implement data tabulation. Results were synthesized by narrative review. This systematic review was prospectively registered in the PROSPERO register (CRD 42022341942). Results: Ten studies (1494 patients) were included. Lung transplantation results in improvements in HRQoL in CF patients relative to their baseline waitlisted state. Up to five years postoperatively CF patients retain their HRQoL at levels similar to the general population. There are several modulating factors that impact HRQoL outcomes in CF patients post-LTx. Compared to lung recipients with other diagnoses CF patients achieve either greater or equal levels of HRQoL. Conclusion: Lung transplantation conveys improved HRQoL to CF patients with the advanced-stage pulmonary disease for up to five years, and to levels comparable to the general population and non-waitlisted CF patients. This systematic review quantifies, using current evidence, the improvements in HRQoL gained by CF patients following lung transplantation.

Predictive ability of severity scores and outcomes for mortality in kidney transplant recipients with coronavirus disease 2019 admitted to the intensive care unit: results from a Brazilian single-center cohort study / Capacidade preditiva de escores de gravidade e desfechos para mortalidade em receptores de transplante renal com COVID-2019 admitidos em unidade de terapia intensiva: resultados de um estudo de coorte brasileiro de um único centro

Abstract Background: the predictive ability of severity scores for mortality in patients admitted to intensive care units is not well-known among kidney transplanted (KT) patients, especially those diagnosed with coronavirus disease 2019 (COVID-19). The purpose of the present study was to evaluate the predictive ability of severity scores for mortality in KT recipients. Methods: 51 KT recipients with COVID-19 diagnosis were enrolled. The performance of the SOFA, SAPS 3, and APACHE IV tools in predicting mortality after COVID-19 was compared by the area under the ROC curve (AUC-ROC) and univariate Cox regression analysis was performed. Results: The 90-day cumulative incidence of death was 63.4%. Only APACHE IV score differed between survivors and nonsurvivors: 91.2±18.3 vs. 106.5±26.3, P = 0.03. The AUC- ROC of APACHE IV for predicting death was 0.706 (P = 0.04) and 0.656 (P = 0.06) at 7 and 90 days, respectively. Receiving a kidney from a deceased donor (HR = 3.16; P = 0.03), troponin levels at admission (HR for each ng/mL = 1.001; P = 0.03), APACHE IV score (HR for each 1 point = 1.02; P = 0.01), mechanical ventilation (MV) requirement (HR = 3.04; P = 0.002) and vasopressor use on the first day after ICU admission (HR = 3.85; P < 0.001) were associated with the 90-day mortality in the univariate analysis. Conclusion: KT recipients had high mortality, which was associated with type of donor, troponin levels, early use of vasopressors, and MV requirement. The other traditional severity scores investigated could not predict mortality.

RESUMO Introdução: a capacidade preditiva dos escores de gravidade para mortalidade em pacientes admitidos em unidades de terapia intensiva não é bem conhecida entre pacientes transplantados renais (TR), especialmente aqueles diagnosticados com doença coronavírus 2019 (COVID-19). Este estudo avaliou a capacidade preditiva dos escores de gravidade para mortalidade em receptores de TR. Métodos: Foram inscritos 51 receptores de TR diagnosticados com COVID-19. O desempenho das ferramentas SOFA, SAPS 3, APACHE IV em predizer mortalidade após COVID-19 foi comparado pela área sob a curva ROC (AUC-ROC) e realizou-se análise de regressão univariada de Cox. Resultados: A incidência cumulativa de óbito em 90 dias foi 63,4%. Somente APACHE IV diferiu entre sobreviventes e não-sobreviventes: 91,2±18,3 vs. 106,5±26,3; P = 0,03. A AUC-ROC do APACHE IV para predizer óbito foi 0,706 (P = 0,04) e 0,656 (P = 0,06) aos 7 e 90 dias, respectivamente. Receber rim de doador falecido (HR = 3,16; P = 0,03), níveis de troponina na admissão (HR para cada ng/mL = 1,001; P = 0,03), escore APACHE IV (HR para cada 1 ponto = 1,02; P = 0,01), necessidade de ventilação mecânica (VM) (HR = 3,04; P = 0,002), uso de vasopressor no primeiro dia após admissão na UTI (HR = 3,85; P < 0,001) foram associados à mortalidade em 90 dias na análise univariada. Conclusão: Receptores de TR apresentaram alta mortalidade, associada ao tipo de doador, níveis de troponina, uso precoce de vasopressores e necessidade de VM. Os outros escores tradicionais de gravidade investigados não puderam predizer mortalidade.

Effects of Wuzhi capsules on tacrolimus concentration in renal transplant recipients with different CYP3A5 genotypes / 中华泌尿外科杂志

Objective:To study the effect of Wuzhi capsules on tacrolimus trough concentration in kidney transplant recipients with different CYP3A5 genotypes.Methods:From June 2015 to October 2019, 162 patients who underwent renal transplantation for the first time were retrospectively analyzed. The patients were divided into two groups, combined and uncombined, according to whether combined with Wuzhi capsules. There were 81 cases in the uncombined group (55 males and 26 females), and 81 in the combined group (62 males and 19 females). There was no significant difference between the two groups( P=0.219). The ages of the uncombined group and the combined group were (39.26±11.91) years old and (37.21±10.88) years old ( P=0.103), the weights were (62.39±11.64) kg and (66.18±13.89)kg ( P=0.298), systolic blood pressure were (147.28±20.24) mmHg and (145.00±16.42) mmHg (1 mmHg=0.133 kPa)( P=0.276), diastolic blood pressure were (92.25±13.87) mmHg and (92.20±12.53) mmHg ( P=0.886), alanine aminotransferase were (12.24±8.59) U/L and (17.06±13.11) U/L ( P=0.015), aspartate aminotransferase were (17.76±9.12) U/L and (16.57±8.37) U/L ( P=0.463), fasting blood glucose were (8.70±3.48) mmol/L and (7.18±2.74)mmol/L ( P=0.006), hemoglobin were (98.96±17.53) g/L and (101.05±18.67) g/L ( P=0.789), creatinine were (665.22±296.55) μmol/L and (797.32±279.32) μmol/L ( P=0.007), estimated glomerular filtration rate were (11.47±14.11) ml/(min·1.73m 2) and (8.85±3.71) ml/(min·1.73m 2) ( P=0.130)in the kidney transplant recipients before surgery. Among the 162 cases in this study, there were 86 cases (53.09%) of CYP3A5*1*3 genotype, 17 cases (10.49%) of CYP3A5*1*1 genotype, 59 cases (36.42%) of CYP3A5*3*3 genotype, and the minimum allele frequency of CYP3A5*1 was 37.04%. In the uncombined group, CYP3A5*1*3 genotype 39 cases (48.15%), CYP3A5*1*1 genotype 5 cases (6.17%), and CYP3A5*3*3 genotype 37 cases (45.68%). In the combined group, CYP3A5*1*3 genotype 47 cases (58.02%), CYP3A5*1*1 genotype 12 cases (14.81%), and CYP3A5*3*3 genotype 22 cases (27.16%), with statistically significant differences in the two groups ( P=0.024). The patients were treated with a triple immunosuppressive regimen (tacrolimus+ mycophenolate mofetil+ glucocorticoid) based on tacrolimus [initial dose: 0.15-0.30 mg/(kg·d)], combination of Wuzhi capsules in the combination group (11.25 mg, twice a day). The trough concentration of tacrolimus was detected by enzyme-linked immunosorbent assay, compare the difference in the trough concentration of tacrolimus between the two groups. The relationship between the effect of Wuzhi capsules and CYP3A5 gene polymorphism was compared, and compare the changes before and after the application of CYP3A5 genotype combined with Wuzhi Capsules. The influencing factors of tacrolimus trough concentration were analyzed by multiple linear regression. Results:In the combined with Wuzhi capsules, the dose corrected trough concentration (C 0/D) of tacrolimus was higher than that in patients without Wuzhi capsules, and the extent of increase was related to genotype. The C 0/D of tacrolimus in patients with CYP3A5*3*3 genotype in the combination and non-combination groups were (12.15±2.95) (ng·ml -1/0.1mg·kg -1·d -1) and (9.99±2.33) (ng·ml -1/0.1mg·kg -1·d -1) ( P=0.004), CYP3A5*1*3 genotype were (11.11±3.20) (ng·ml -1/0.1mg·kg -1·d -1) and (6.86±1.62) (ng·ml -1/0.1mg·kg -1·d -1) ( P<0.001), and there were significant difference. However, CYP3A5*1*1 genotype were(8.29±2.64) (ng·ml -1/0.1mg·kg -1·d -1) and (6.16±2.87) (ng·ml -1/0.1mg·kg -1·d -1) ( P=0.160), there was no significant difference. The tacrolimus C 0/D of the combined group before and after the Wuzhi capsule were as follows: CYP3A5*3*3 genotype: (7.18±2.33)(ng·ml -1/0.1mg·kg -1·d -1) and (13.33±3.09) (ng·ml -1/0.1mg·kg -1·d -1) ( P<0.001); CYP3A5*1*3 genotype: (5.14±2.14) (ng·ml -1/0.1mg·kg -1·d -1) and (10.61±3.20) (ng·ml -1/0.1mg·kg -1·d -1) ( P<0.001); CYP3A5*1*1 genotype: (5.17±3.75) (ng·ml -1/0.1mg·kg -1·d -1) and (8.31±2.74) (ng·ml -1/0.1mg·kg -1·d -1)( P=0.002), and the differences were statistically significant. The results of multiple linear regression showed that the combination of Wuzhi capsules (β=0.508, P<0.001) and CYP3A5 genotype(CYP3A5*1*3 and CYP3A5*3*3: β=-0.361, P<0.001; CYP3A5*1*1 and CYP3A5*3*3: β=-0.425, P<0.001)could influence the trough concentration. The sex (β=-0.100, P=0.124) and age (β=-0.003, P=0.967) of renal transplant recipients had no statistical significance to tacrolimus C 0/D. Conclusions:In the renal transplant patients, CYP3A5 genotype and combined use of Wuzhi capsules are the main factors affecting tacrolimus C 0/D. In order to achieve the expected trough concentration as soon as possible, the interaction between CYP3A5 genotypes and drug combination should be considered.

Infection with high-risk genotypes of human papillomavirus and cervical cytological findings among kidney transplant recipients in Kenya: a single centre experience

Background: High-risk human papillomavirus (hrHPV) infection is linked with uterine cervix premalignant lesions and invasive carcinoma of the uterine cervix. Methods: Descriptive cross sectional study carried out among female kidney transplant (KTx) recipients in Kenyatta National Hospital, Nairobi-Kenya. We studied the risk factors for acquisition of hrHPV, examined cervical cytology and assayed for 14 hrHPV DNA using Cervista® HPV HR test and Cervista® MTA (Hologic®) automated platforms. Results: The 14-hrHPV genotypes assayed were 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68 and the prevalence rate was 31.25 % (10/32). Abnormal cervical cytology was noted in 4/32 (12.5%) and included low-grade squamous intraepithelial lesion (2/32), atypical squamous cells of undetermined significance (1/32) and atypical glandular cells (1/32). The average age was 41.9years with mean age at first coitus being 20.4 years. Majority of the women 20(62.5%) were married while 8(25%) were single. About 18(56.3%) had only one sexual partner. About 20% of women were nulliparous and 4(12.5%) had a parity of five. Duration sincetransplantation ranged between 1-21 years. Conclusions: The burden of hrHPV and abnormal cervical cytology in our study seemed lower than that reported elsewhere and even in general population. This study may form basis for further studies about HPV infections and carcinoma of the uterine cervix among the kidney allograft recipients in our setting

Cytomegalovirus pneumonia presenting as pulmonary nodules

Abstract Cytomegalovirus (CMV) pneumonia is a well-known cause of morbidity and mortality in patients with a history of allogenic hematopoietic stem cell transplant. Radiographically, CMV pneumonia most commonly presents as bilateral ground glass opacities; however, the presentation is non-specific and can be variable, including presenting as areas of air-space consolidation or pulmonary nodules. We report a case of a 70-year-old man who presented with rapidly progressive bilateral pulmonary nodules approximately two months after receiving a bone marrow transplant. No infectious etiology was identified for the pulmonary nodules, and a bronchoscopy was unable to be performed due to a rapid decline in the patient's overall condition and respiratory status. The patient died shortly after the decision was made to transition to palliative care and a limited autopsy was performed to explore the pulmonary findings. Corresponding to premortem imaging were the postmortem gross findings of numerous bilateral pulmonary nodules and a large mass-like area of consolidation in the right upper lobe. Microscopic examination of the nodules demonstrated a necrotizing pneumonia with few foci of viral cytopathologic change consistent with CMV, which was confirmed by immunohistochemistry. While CMV is a common infectious agent in the immunocompromised population, CMV pneumonia continues to be a challenging entity due to difficulty in diagnosis and treatment. Rapidly enlarging pulmonary nodules in an immunosuppressed patient is highly suggestive of an infectious process and careful histologic examination for viral cytopathologic change is essential.

Características clínicas y microbiológicas de infecciones del torrente sanguíneo en pacientes adultos neutropénicos / Clinical and microbiological characteristics of bloodstream infections in adult neutropenic patients

RESUMEN Las infecciones del torrente sanguíneo (IS) en pacientes oncológicos neutropénicos constituyen una patología de relevancia y se asocian a un aumento de la morbimortalidad. El objetivo de este estudio fue determinar las características epidemiológicas y microbiológicas de los episodios de IS en pacientes adultos neutropénicos con neoplasias hematológicas (NH) y neoplasias sólidas (NS). Se realizó un estudio retrospectivo en dos hospitales de tercer nivel entre 2009 y 2016. Se incluyeron todos los pacientes neutropénicos mayores de 18años con NH y NS que presentaron episodios de IS. Se excluyeron aquellos con neoplasias dermatológicas no melanoma. Se identificaron 143 episodios de IS, de los cuales el 80,4% fueron en personas con NH. El 97,9% de los pacientes tuvieron neutropenia de alto riesgo, sin diferencia entre los grupos NH y NS. Los orígenes más frecuentes de IS fueron bacteriemia primaria (46,9%) e infección asociada a catéter (21%), sin diferencias significativas entre grupos. El 74,1% de los aislamientos fueron bacilos gram negativos yEscherichiacolifue el microorganismo más frecuente (32,1%). El coco gram positivo más frecuentemente aislado fueStaphylococcusaureus(28,1%), seguido del grupo de los estafilococos coagulasa negativos (ECN), sin diferencias entre ambos tipos de neoplasias. El 67,5% de los ECN fueron multirresistentes; solo el 11,1% de los aislamientos deS. aureusfue resistente a la meticilina. El 17,6% de los aislamientos deE. coliy el 27,6% de los deKlebsiellapneumoniaefueron multirresistentes. No hubo diferencias en la frecuencia de aislamientos multirresistentes al comparar entre ambos tipos de neoplasia. Como conclusión, las IS en pacientes neutropénicos fueron más frecuentes en pacientes con NH y las causaron, principalmente, bacilos gram negativos. Se observó una elevada mortalidad en los pacientes neutropénicos con IS.

ABSTRACT Bloodstream infections (BI) are relevant in neutropenic patients because they are associated with an increased number of complications and death. The objective was determinate the epidemiologic and microbiologic features of the BI in neutropenic patients with solid neoplasm (SN) and hematologic neoplasm (HN). Retrospective study in two third level hospitals between 2009 and 2016. They were included all the patients older than 18 years-old with active oncologic disease and neutropenia, who had BI. Patients with dermatologic cancer other than melanoma where excluded. A total of 143 BI in neutropenic were observed, of which 80.4% occurred in HN. Around 97.9% of the patients had a high-risk neutropenia without differences between both groups. The most frequent site of BI was primary bacteremia (46.9%) and catheter-associated infection (21%), without significant differences between the two groups. The gram negatives bacilli (GNB) predominated over the gram positive cocci (GPC) and they represented 74.1% of the isolated bacteria, beingEscherichia colithe most frequent (32.8%). Among the gram positive cocci,Staphylococcus aureus(28.1%) was the most frequent isolated, followed by coagulase-negativeStaphylococci(CNS). There were no differences in microbiological isolates between both groups. With regard to the antimicrobial susceptibility 67.5% of the CNS, 17.6% of theE. coliand 27.6% of theKlebsiella pneumoniaewere multiresistant with no differences between both groups. Only 11.1% of S. aureus isolates were methicillin resistant. In conclusion BI of the neutropenic patients where most frequents within patients with HN, GNB were the main microbiological isolates. High mortality was observed in neutropenic patients with BI.

Study on the effect of unilateral donor kidney donated by child for adult recipient transplantation / 中华器官移植杂志

Objective:To evaluate the effect of unilateral pediatric kidney donation for adult kidney transplantation.Methods:Retrospective analysis was conducted on the cases of children who donated unilateral donor kidney for adult kidney transplantation recipients in our hospital, and those who were followed up for more than three years were included in this study. The body weight of the recipients in group A was ≤50 kg, and the body weight of the recipients in group B was ≤70 kg.The recipients were divided into 0-5 year old donor group (group A) and 6-17 year old donor group (B group). Clinical data, recipient/kidney survival, graft function and growth, and complications of the recipient were analyzed.Results:A total of 45 adult recipients were enrolled, including 12 in group A and 33 in group B. The renal survival rate at 3 years after operation was (100%, 96.9%)/(91.6%, 93.9%). One week after the operation, the early postoperative recovery of renal function in group B was better than that in group A, and the difference of serum creatinine was statistically significant ( P<0.05), while the difference of serum creatinine in other postoperative follow-up time points was not statistically significant ( P>0.05). Within a year, both groups of grafts continued to grow, reaching adult levels in one year. There was no statistical significance in the incidence of complications between the two groups ( P>0.05). The incidence of protein in the two groups was 33.3% and 6.1%, respectively, 1 case in each group still had proteinuria at 1 year after surgery, and only 1 case in the infant donor kidney recipient in group A had proteinuria at 3 years after surgery. Conclusions:Unilateral donor kidney transplantation from children can provide good results for adult patients with uremia by selecting suitable donors according to the weight of the recipient.

Assessment of the health status and its influencing factors in target recipients of the precision poverty alleviation program in Zigui County in 2018 / 公共卫生与预防医学

Objective To investigate the current health status of the targeted recipients of the precision poverty alleviation program in Taiziwan Village, Shazhenxi Town, Zigui County and explore its influencing factors, and to provide reference for the formulation of local health poverty alleviation policies. Methods A cluster sampling method was used to investigate 115 poverty alleviation recipients aged 18 and above in Taiziwan Village. The status of “physiological health” and “mental health” was investigated using the international general SF-36 (Chinese version) health scale. Results The survey subjects were mainly the people with advanced age, low education background and suffering from chronic diseases. Except for the physiological function score being more than 70 points, the scores of other dimensions were all 60 points around. The scores were 61.74±19.86 points for physical health and 59.05±16.91 points for mental health, respectively. People aged 60 and above scored lower in all dimensions than those aged under 60. Factors that affected both physical and mental health of the whole population were advanced age and chronic diseases. While the factors that affected physical health of people aged 60 and above were chronic diseases, the factors that affected mental health were chronic diseases and a long interval between children's home visits. Conclusion The health status of people aged 60 and above is worse than that of people aged below 60. Their physical health is affected by chronic diseases, and their mental health is affected by chronic diseases and children's visit cycles. While formulating poverty alleviation policies for physical health, an attention should also be paid to mental health.

Research advances in improving the prognosis of recipients of fatty liver transplantation / 临床肝胆病杂志

With the increasing demand for liver donors, more and more marginal donors have been used. How to use fatty liver grafts has become a new issue that physicians in the department of liver transplantation must face. Compared with the normal donor liver, fatty liver grafts have high incidence of postoperative complications and increase the difficulty of clinical cure. This review describes the measures to improve the prognosis of recipients of fatty liver transplantation, and points out that these measures can reduce the risk of fatty liver transplantation and thus increase the utilization of fatty liver grafts.

Tratamento farmacológico da estrongiloidíase em pacientes transplantados / Pharmacological treatment of strongilloidiasis in transplanted patients

O objetivo deste artigo foi comparar o uso da ivermectina e do albendazol em pacientes transplantados e relatar os respectivos sucessos terapêuticos nessa população. Foram analisados artigos que abordassem relatos de casos publicados nos últimos 4 anos no PubMed® relacionando os descritores "transplante de órgãos", "estrongiloidíase" e "tratamento". Foram encontrados e analisados dez relatos de caso que abordaram a estrongiloidíase em situa- ção pós-transplante contemplando 13 indivíduos. Desses, cinco (38,5%) utilizaram ambos os medicamentos, dos quais quatro (80%) se curaram, tendo recebido albendazol e ivermectina por via subcutânea (50%) ou albendazol e ivermectina por vias oral/ subcutânea (50%). O paciente que morreu recebeu albendazol e ivermectina por via subcutânea. Sete (53,8%) indivíduos utiliza- ram apenas ivermectina, dos quais três (42,8%) se curaram tendo recebido o medicamento oral (dois pacientes) ou subcutâneo (um paciente); dois (28,6%) morreram recebendo o medicamento via oral, dois (28,6%) usaram profilaticamente via oral e apenas um não manifestou sintomas. Apenas um (7,7%) indivíduo utilizou somente albendazol via oral tendo sobrevivido à infecção. A uti- lização combinada dos medicamentos ivermectina e albendazol parece ter efeito positivo no tratamento da estrongiloidíase. A administração da ivermectina por via subcutânea apresentou resultados promissores, contudo estudos controlados de siner- gia medicamentosa e vias de administração devem ser realizados para efetiva avaliação.

The objective of this article was to compare the use of ivermec- tin and albendazole in transplanted patients and to report the respective therapeutic successes in this population.Articles ad- dressing case reports published in the last 4 years in the PubMed relating the descriptors "organ transplantation", "strongyloidia- sis", and "treatment" were analyzed. Ten case reports addres- sing strongyloidiasis in a post-transplant situation, covering 13 individuals, were found and analyzed. Of these, five (38.5%) used both drugs of which 4 (80%) were cured having received subcu- taneous albendazole and ivermectin (50%) or oral/subcutaneous albendazole and ivermectin (50%). The patient who died received subcutaneous albenzadole and ivermectin. Seven (53.8%) indi- viduals used only ivermectin, of which three (42.8%) were cured having received the oral (2/3) or subcutaneous (1/3) medication, two (28.6%) died receiving the oral medication, and two (28.6%) used oral medication prophylactically, and only one did not show symptoms. Only one (7.7%) individual used only oral albenzadole and survived the infection. The combined use of the drugs iver- mectin and albendazole seems to have a positive effect on the treatment of strongyloidiasis. The administration of subcuta- neous Ivermectin has shown promising results; however, con- trolled studies of drug synergy and administration routes shall be performed for effective evaluation.

Association of UGTs, ABCC2, SLCO1B1 and IMPDH Gene Polymorphisms with the Metabolism and Adverse Reactions of Mycophenolate Ester in Renal Transplant Patients / 中国药学杂志

OBJECTIVE: To investigate the association of UGTs, ABCC2, SLCO1B1 and IMPDH gene polymorphisms with metabolism and adverse reaction of mycophenolate ester in early renal transplant recipients. METHODS: A total of 233 patients who received tacrolimus+glucocorticoid+mycophenolate mofetil treatment after living kidney transplantation were enrolled. Single nucleotide polymorphisms of 13 gene were detected by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Kruskal-Wallis H test was used to analyze the effect of 13 single nucleotide polymorphisms on the exposure/dose (AUC/D) and adverse reactions of mycophenolic acid in early recipients after renal transplantation. RESULTS: The AUC/D of mycophenolic acid in UGT2B7 802C>T CC and CT genotype recipients was (36.03±16.19) and (38.06±15.41) mg•h•L-1/g•d-1, which was significantly lower than that in TT genotype recipients (43.63±15.10) mg•h•L-1/g•d-1 (P=0.021). The AUC/D of mycophenolic acid in SLCO1B1 521T > C TT, TC and CC genotype recipients were (36.78±15.70), (41.27±12.92) and (45.10±21.32) mg•h•L-1/g•d-1, respectively. There was significant difference between groups (P=0.036). There was no significant difference between 13 single nucleotide polymorphisms and adverse reactions (P>0.05). CONCLUSION: The AUC/D of mycophenolic acid in early recipients after kidney transplantation are associated with the polymorphism of UGT2B7 802C > T and SLCO1B1 521T > C.

Infecção por parvovírus B19 em receptores de transplante renal: série de caso / Parvovirus B19 infection in kidney transplant recipients: a case series

Os receptores de transplante renal são mais suscetíveis a infecções, entre elas o parvovírus B19, que pode ser transmitido por via respiratória, adquirido por meio do enxerto ou por reativação de infecção latente. A anemia normocítica normocrômica, com diminuição dos reticulócitos e resistência ao tratamento com eritropoietina, é a principal forma de apresentação da infecção por parvovírus B19 em transplante renal. O diagnóstico requer alto índice de suspeição clínica e realização de testes diagnósticos selecionados. Tratamento com imunoglobulina e suspensão dos imunossupressores durante a infecção mostraram-se eficazes. Os autores relatam sua experiência com cinco casos de infecção por parvovírus B19 em receptores de transplante renal de um hospital universitário. Os aspectos clínicos, diagnósticos e terapêuticos são revistos.

Kidney transplant recipients are more susceptible to infections, including by parvovirus B19, spread through the respiratory tract, acquired through the graft or reactivation of latent infection. Normocytic normochromic anemia, with decreased reticulocytes and resistance to erythropoietin treatment, is the most common presentation of Parvovirus B19 infection in renal transplant. Diagnosis requires a higher clinical suspicion and the performance of selected diagnostic tests. Treatment with immunoglobulin and suspension of immunosuppressive therapy during the infection may be effective. The authors report five cases of PB19 infection in kidney transplant patients at a hospital. The clinical, diagnostic, and treatment features are reviewed.
