RESUMO

OBJECTIVES: To analyze the clinical and economic burden of community-acquired (CA) or community-onset healthcare-associated (COHCA) multidrug-resistant (MDR) infections requiring hospitalization. METHODS: Case-control study. Adults admitted with CA or COHCA MDR infections were considered cases, while those admitted in the same period with non-MDR infections were controls. The matching criteria were source of infection and/or microorganism. Primary outcome was 30-day clinical failure. Secondary outcomes were 90-day and 1-year mortality, hospitalization costs and resource consumption. RESULTS: 194 patients (97 cases and 97 controls) were included. Multivariate analysis identified age (odds ratio [OR], 1.07, 95% confidence interval [CI], 1.01-1.14) and SOFA score (OR, 1.45, CI95%, 1.15-1.84) as independent predictors of 30-day clinical failure. Age (hazard ratio [HR] 1.09, 95%CI, 1.03-1.16) was the only factor associated with 90-day mortality, whereas age (HR 1.06, 95%CI, 1.03-1.09) and Charlson Index (HR 1.2, 95%CI, 1.07-1.34) were associated with 1-year mortality. MDR group showed longer hospitalization (p<0.001) and MDR hospitalization costs almost doubled those in the non-MDR group. MDR infections were associated with higher antimicrobial costs. CONCLUSIONS: Worse economic outcomes were identified with community-onset MDR infections. MDR was associated with worse clinical outcomes but mainly due to higher comorbidity of patients in MDR group, rather than multidrug resistance.

RESUMO

RESUMEN Objetivos Analizar las características clínicas, bioquímicas, estudios complementarios, hallazgos moleculares y la prevalencia de glándula eutópica en neonatos con HC pertenecientes al Programa Provincial de Pesquisa Neonatal de Córdoba, Argentina, entre 1996 y 2015. Analizar la evolución de los pacientes que reunieron criterios para una reevaluación. Pacientes y métodos Se analizaron retrospectivamente las historias clínicas de 237 pacientes detectados por pesquisa neonatal en la provincia de Córdoba, Argentina, entre 1996-2015 con una incidencia promedio de 1/2146 pesquisados. Presentaron glándula eutópica 81 pacientes (34%) F35/M46; se excluyeron 10 con síndromes genéticos asociados. Se analizaron los niveles de: TSH, T4T, T4L, T3, TPOAb / TGAb y Tiroglobulina (ECLIA -ROCHE) (VR: >15 días: 6-83 ng/ ml; <15 días: 29-173 ng/ml), ecografía y centellografía de cuello con Tc-99m. El valor de corte de TSH sérica adoptado para la confirmación diagnóstica fue de ≥10 mUI/ml. Se realizaron estudios de biología molecular en casos seleccionados. Se reevaluaron niños mayores de 3 años, sin bocio, con valores normales de Tiroglobulina y sin requerimiento de incrementos en la dosis de LT4. Resultados: La prevalencia de HC y Tiroides Eutópica se mantuvo constante. El 50% de los pacientes (36/71) mostraron hiperplasia glandular tiroidea. El 84% (n: 60 de 71) presentó niveles de TSH sérica ≥20 uUI/ml (20-1186) y el 75% (n: 53 de 71) >40 uUI/ml (40-1186). TGAb and TPOAb fueron positivos en un niño. La determinación de TG fue normal en el 29% (21/71) de los casos, elevada en el 56% (39/71) y baja en el 14% (10/71). Los estudios de biología molecular resultaron diagnósticos en 26 pacientes de 18 familias, demostrándose mutaciones en los genes de: TPO: 9 pacientes, TG: 12 pacientes, NIS: 2 pacientes, DUOX2: 2 pacientes y TRβ: 1 paciente. Se encontraron 11 nuevas mutaciones: tres en TPO, cinco en TG, dos en NIS y una en DUOX2. Se informaron anomalías congénitas en el 11% (8/71) de los pacientes. Se reevaluó el 11% (8/71) de los niños, resultando: HC transitorio n: 5, permanente n: 2 y una niña con Síndrome de Resistencia a las Hormonas Tiroideas. La prevalencia de lactantes con HC y glándula eutópica se mantuvo constante a lo largo de 19 años del Programa. Conclusiones Nuestros estudios demuestran que la prevalencia de Hipotiroidismo Congénito con glándula eutópica se mantuvo estable en los períodos analizados. Este grupo de pacientes se caracterizó predominantemente por presentar HC de carácter permanente acompañado por fenotipos de moderada a severa intensidad. En el futuro deberá profundizarse el conocimiento respecto a la influencia de factores medioambientales, como posibles agentes de riesgo asociados a la génesis de Hipotiroidismo Congénito.


abstract Objectives To describe clinical, biochemical characteristics and complementary studies to diagnosis, molecular findings and the prevalence of eutopic gland in newborn with CH detected through our neonatal screening program in Córdoba, Argentina, between 1996 and 2015. To analyze the evolution of the patients who met criteria for re-evaluation. Patients and methods We retrospectively analysed medical records of 237 patients with CH detected by neonatal screening in Córdoba, Argentina, from 1996 to 2015 with an average incidence of 1/2146 researched. 81 patients (34%) F35/M46 had eutopic thyroid gland; 10 patients with associated genetic syndromes were excluded. TT4, FT4, T3, TSH, TPOAb, TGAb and Thyroglobulin (VR: >15 days: 6-83 ng/ml; <15 days: 29-173 ng/ml) (ECLIA ROCHE), thyroid ultrasonography and 99Tc scan were assessed. The serum TSH cutoff value adopted for diagnostic confirmation was ≥10 mIU/ml. Molecular biology studies were performed in selected cases. Those who had no goiter, with normal thyroglobulin, and had not required increases in L-T4 dose underwent re-evaluation after the age of 3 years. Results The prevalence of HC and thyroid Eutopic remained constant. 50% of the patients (36/71) showed glandular hyperplasia. In 84% (60/71) presented serum TSH levels ≥20 uUI/ml (20-1186) and in 75% (n: 53 of 71) levels >40 uUI/ml (40-1186). TGAb and TPOAb were positive only in one baby. TG levels were: normal in 29% (21/71) of the cases, elevated in 56% (39/71) and low in 14% (10/71). Gene mutations were found in 26 patients from 18 families: TPO: 9 patients, TG: 12 patients, NIS: 2 patients, DUOX2: 2 patients y TRβ: 1 patient. Eleven new mutations were found: three in TPO, five in TG, two in NIS and one in DUOX2. Congenital anomalies were reported in 11% (8/71) patients. The 11% (8/71) of children were re-evaluated resulting in: 5 Transient CH, 2 Permanent CH and 1 with Resistance to Thyroid Hormones. The prevalence of infants with CH and eutopic gland remained constant along 19 years of the Program. Conclusions Our studies show that the prevalence of congenital hypothyroidism with eutopic gland remained stable in the periods analyzed. This group of patients was predominantly characterized by permanent CH accompanied by moderate to severe phenotypes. In the future, knowledge about the influence of environmental factors, as possible risk agents associated with the genesis of Congenital Hypothyroidism, should be deepened.

RESUMO

Cat scratch disease is an infectious disorder transmitted by cats that typically affects children and young adults. Immunosuppression is a well-known risk factor for the development of severe and atypical forms of the disease; hence it is under-diagnosed in patients with compromised immunity. We are reporting the first case of cat scratch disease, which presented as fever and fatigue, in a patient with systemic lupus erythematosus while receiving immunosuppressant therapy after a kidney transplant.

RESUMO

Activated regulatory T cells (aTregs) are nowadays a hot topic in organ transplantation to establish their role during acute rejection (AR) episodes. The aim of this multi-center study was to monitor the frequency of aTregs within the first year after transplantation in a cohort of first-time liver transplant recipients enrolled from 2010 to 2012. aTregs frequency was analyzed by means of flow cytometry. Patients who had AR showed higher levels of aTregs during first year after transplantation in comparison with patients who did not have higher levels. High levels of aTregs in liver recipients might be used as a biomarker of AR; however, further studies must be done to address the potential role of aTregs as biomarkers of AR in liver transplantation.

RESUMO

AIMS: To investigate an optimal long-term prophylactic strategy for prevention of hepatitis B virus (HBV) recurrence after liver transplantation, we conducted a randomized study of 29 transplant recipients receiving a short course of hepatitis B immune globulin (HBIg) + lamivudine (LAM), followed by randomization to long-term prophylaxis with LAM with or without HBIg. METHODS: The efficacy and safety, and impact on survival and HBV recurrence of these 2 prophylactic regimens were compared over a mean period of 10 years. In patients with viral recurrence, the HBV quasispecies in the surface/polymerase region were studied by ultra-deep pyrosequencing (UDPS). RESULTS: The 10-year survival rate was 76% and was not affected by the type of prophylaxis. Four patients had hepatitis B surface antigen (HBsAg) recurrence within the first 48 months after orthotopic liver transplantation (OLT). HBsAg-positive and -negative patients showed similar mean survival times, with no differences between the 2 regimens. Low HBV DNA levels were transiently detected in 32% of HBsAg-negative patients. UDPS showed major changes after OLT in the HBV quasispecies of patients with viral recurrence, which may be explained by a "bottleneck" effect of OLT together with prophylactic therapy. CONCLUSION: Long-term survival after OLT in end-stage chronic hepatitis B patients was good with both prophylactic strategies. However, low, transient HBV DNA levels were detected even in the absence of HBsAg, showing the importance of continuing HBV prophylaxis.

RESUMO

BACKGROUND: We report our initial gastric electrical stimulation experience using the abiliti® system for the treatment of obese patients followed for 1 year. METHOD: Between March 2011 and June 2013, 27 obese patients (BMI 30 to 46 kg/m(2)) were enrolled in a prospective open label study and implanted with a gastric stimulator. The patients were provided with nutritional support, and sensor-based behavioral feedback. RESULTS: At 12 months, percent excess weight loss (%EWL) obtained was 49.3 ± 19.2 % with no significant differences between gender or age sub-groups. The %EWL data were segmented into two groups according to BMI 30-40 kg/m(2) patients (obesity grade I and II) and BMI >40 kg/m(2), with the results of weight loss being significantly higher for the lower BMI group (59.1 ± 19.5 vs. 46.7 ± 13.4, respectively, p < 0.01). One subject requested to have his device explanted, and the minor postoperative adverse events were resolved without hospital admission. All patients experienced early satiety and reduced their intake. CONCLUSIONS: After 12 months of follow-up, gastric electrical stimulation treatment appears to be a safe and effective option for weight loss in obese subjects. Long-term follow-up and further studies are warranted.

RESUMO

Anti-inflammatory cytokines have an important role in disease, tumour and transplant processes. Alterations in the regulation of several cytokines have been implicated in a variety of inflammatory disorders, including IBD (inflammatory bowel disease) [Crohn's disease (CD) and ulcerative colitis (UC)]. Cytokine polymorphisms are also known to affect the level of gene expression. Thus, the aim of this study was to determine the relationship between cytokine polymorphisms and the IBD pathologies in a Spanish population. Polymorphisms analysis was performed using PCR-SSOP using a microbeads luminex assay. The following polymorphisms were determined: TNFα [-238G/A (rs361525) and -308G/A (rs1800629)], IFNγ [+874A/T (rs62559044)], TGFß [+869C/T (rs1982073) and +915G/C (rs1800471)], IL10 [-1082A/A (rs1800896), -592A/C (rs1800872), -819C/T (rs1800871)], IL6 [-174C/G (rs1800795)], IL12p40 [3'UTR -1188A/C (rs3212227)], IL1α [-889C/T (rs1800587)], IL1ß [-511C/T (rs1143634) and +3962C/T (rs1143633)], IL1R [Pst-1 1970C/T] and IL1RA [Mspa-1 11100C/T]. No statistical differences in TNFα, IFNγ, TGFß, IL10, IL6, IL1α, IL1ß, IL1R and IL1Ra genotypes and allele distributions between the IBD groups and healthy controls were found. However, we observed significant differences in the 3'UTR -1188A/C polymorphism of IL12p40. So -1188A allele was increased in patients with UC and the -1188C allele (high IL12p40 production) was increased in patients with CD with respect to controls. These data are in concordance with the fact that CD has been shown to be associated with a Th1 T-cell-mediated inflammation model and high IL12/IFNγ production at histological affected sites. These data suggest that cytokine polymorphisms in TNFα, IFNγ, TGFß, IL10, IL6 and IL1α, IL1ß, IL1R and IL1Ra cytokine gene do not seem to be relevant in IBD susceptibility and IL12p40 3'UTR -1188A/C polymorphism seems to be associated with a differential IBD development.

RESUMO

A significant proportion of transplant patients undergoing immunosuppressant therapy experience gastrointestinal (GI) symptoms. The SIGIT-QoL is a brief instrument developed to measure adverse gastrointestinal effects on patients' health-related quality of life (HRQoL). The goal of this study was to analyze the psychometric properties of the SIGIT-QoL that are required for its use in clinical research and practice, especially its value for detecting changes in the impact of gastrointestinal symptoms on HRQoL of solid organ transplant (SOT) recipients. To this end, an observational, multicenter, prospective study was conducted. SOT patients aged ≥18 years who had received the graft 3 to 24 months before and were experiencing gastrointestinal symptoms were evaluated at baseline, 1 to 2 weeks later, and 3 months after baseline. Sociodemographic and clinical data recorded included: age, sex, SOT type (lung, kidney, liver, or heart), acute allograft rejection, gastrointestinal etiology, Clinical Global Impressions (CGI) and Patient Global Impression (PGI) Severity of Illness (SI) and Global Improvement (GI) scores, and the SIGIT-QoL (scores range from 0 [maximum impact] to 68 [minimum disruption]). Intraclass correlation coefficients, differences between baseline and last visit (Wilcoxon test), effect size (Cohen's d), the minimal important differences (using CGI and PGI scores as anchors in General Linear Models), and the cutoff score (receiver-operating characteristic analysis) were calculated. In total, 277 SOT patients (61.4% male) were included. Mean ± SD age was 52.69 ± 11.65 years, time since transplantation was 12.31 ± 6.74 months, and 22.4% experienced an acute allograft rejection. At baseline, total SIGIT-QoL mean scores (51.21 ± 11.25) showed an impact on patients' HRQoL that was diminished 3 months later (57.40 ± 8.38; P < .001). SIGIT-QoL test-retest reliability was adequate (intraclass correlation coefficient, 0.740-0.895). A moderate effect size (d = -0.550) was found. Moreover, a minimal important difference of 4.2 points in total scores was found (F4,223 = 16.917 [P < .001] and F4,224 = 25.138 [P < .001]). Finally, a cutoff point (55.00 points) was estimated (area under the concentration-time curve, 0.846 [95% confidence interval, 0.798-0.894], P < .001; sensitivity, 0.793; specificity, 0.713; negative likelihood ratio, 0.290; positive likelihood ratio, 2.762). We concluded that the SIGIT-QoL is a feasible (average completion time, <6.5 minutes), reliable, and valid instrument for assessing the impact of gastrointestinal symptoms on the HRQoL of SOT patients.

RESUMO

Acute rejection (AR) remains a major challenge in organ transplantation, and there is a need for predictive biomarkers. In the present multicenter study, we prospectively examined a series of biomarkers in liver and kidney recipients. Intracellular expression of IFN-γ, IL-17 and IL-2 and IL-17 soluble production were evaluated both pre-transplantation and post-transplantation (1st and 2nd week, 1st, 2nd and 3rd month). 142 transplant patients (63 liver/79 kidney) were included in the study. Twenty-eight recipients (14 liver/14 kidney) developed AR. Pre- and post-transplantation intracellular expression of %IFN-γ(+) in CD4(+)CD69(+) and in CD8(+)CD69(+) and soluble IL17 identified liver and kidney transplant patients at high risk of AR. Pre-transplantation, %IL-2(+) in CD8(+)CD69(+) also identified kidney patients at high risk. We constructed pre- and post-transplantation risk prediction models, based on a composite panel of biomarkers, which could provide the basis for future studies and will be a useful tool for the selection and adjustment of immunosuppressive treatments.

RESUMO

Tumour necrosis factor alpha (TNF-α) has an important role in inflammatory response. Alterations in the regulation of TNF-α have been implicated in a variety of inflammatory disorders, including Inflammatory bowel disease (IBD). Indeed, a common treatment for IBD is the use of TNF-α inhibitors. Polymorphisms in the TNF-α promoter region are known to affect the level of gene expression. Our aim was to investigate the influence of these single nucleotide polymorphisms (SNPs) in TNF-α promoter gene play in the risk of IBD in a Spanish population and their individual response to anti-TNF-α treatment. DNA samples from patients with IBD and controls were screened for TNF-α -238G/A (rs361525) and -308G/A (rs1800629) SNPs by PCR-SSOP using a microbeads luminex assay and compared with response to TNF-α inhibitors. There were not statistical differences in -238G/A and -308G/A allele and genotype frequencies between patients. However, we found an increased frequency of -308A allele and -308GA genotype in these nonresponders patients to TNF-α inhibitors with respect to responders patients (Pc < 0.05). This -308GA genotype has been classified as high producer of this cytokine. This fact could actually be interesting to explain the different response of patients with IBD with respect to TNF-α inhibitors. TNF-α promoter gene polymorphism does not seem to play a role in IBD susceptibility, but particular TNF-α genotypes may be involved in the different responses to TNF-α inhibitor treatment in Spanish patients with IBD.

RESUMO

BACKGROUND: "Anxious preoccupation" is a maladaptive coping strategy for patients with terminal chronic liver pathology causing psychopathologic emotional responses. The aim of this study was to identify "anxious preoccupation" as a coping strategy when faced with this disease and to investigate its relationship with emotional-type psychopathologic symptoms in patients awaiting a liver transplant (LT). METHODS: A total of 63 patients awaiting an LT were evaluated. The instrument used to evaluate coping style was the Mental Adjustment to Cancer questionnaire. One of the coping scales of this questionnaire is "anxious preoccupation" (9 items). An Instrument for psychopathologic assessment was used, the SA-45 questionnaire, which assessed 9 psychopathologic dimensions: somatizations, obsessions-compulsions, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. RESULTS: "Anxious preoccupation" was used as an inadequate coping style by 51% of patients when faced with the disease. Five psychopathologic dimensions were associated with this coping strategy: 1) obsessive-compulsivity: 75% of patients with "anxious preoccupation" had obsessive-compulsivity symptoms compared with 29% of patients with other coping strategies (P < .001); 2) interpersonal sensitivity: 25% vs 6%, respectively (P = .044); 3) depression: 59% vs 29% (P = .015); 4) anxiety: 75% vs 32% (P = .001); and 5) phobic anxiety: 19% vs 3% (P = .050). CONCLUSIONS: More than one-half of the patients on the LT waiting list used "anxious preoccupation" as a coping style for this disease. This strategy was associated with a greater presence of emotional-type psychopathologic symptoms in these patients.

RESUMO

In this study, we investigated and compared the microbial communities adhering to the obverse and the reverse sides of an oil painting on canvas exhibiting signs of biodeterioration. Samples showing no visible damage were investigated as controls. Air samples were also analysed, in order to investigate the presence of airborne microorganisms suspended in the indoor atmosphere. The diversity of the cultivable microorganisms adhering to the surface was analysed by molecular techniques, such as RAPD analysis and gene sequencing. DGGE fingerprints derived from DNA directly extracted from canvas material in combination with clone libraries and sequencing were used to evaluate the non-cultivable fraction of the microbial communities associated with the material. By using culture-dependent methods, most of the bacterial strains were found to be common airborne, spore-forming microorganisms and belonged to the phyla Actinobacteria and Firmicutes, whereas culture-independent techniques identified sequenced clones affiliated with members of the phyla Actinobacteria and Proteobacteria. The diversity of fungi was shown to be much lower than that observed for bacteria, and only species of Penicillium spp. could be detected by cultivation techniques. The selected strategy revealed a higher microbial diversity on the obverse than on the reverse side of the painting and the near absence of actively growing microorganisms on areas showing no visible damage. Furthermore, enzymatic activity tests revealed that the most widespread activities involved in biodeterioration were esterase and esterase lipase among the isolated bacterial strains, and esterase and N-acetyl-ß-glucosaminidase among fungi strains.

RESUMO

Despite the improved overall outcomes of liver transplantation as a result of advances in surgical techniques and improved immunosuppressive control, biliary complications (BCs) continue to be the most common cause of morbidity in liver transplant recipients. The objectives of this study were to analyze the incidence, type, and management of BCs over a 20-year period. We performed a comparative study of two groups of liver transplant patients in our unit operated on by the same surgical team: group I consists of the first 300 liver transplant patients (1989-1992), and group II is composed of the last 300 liver transplants (2007-2011). We found no significant differences in the number of cases of biliary leakage whether or not a Kehr T-tube was used. However, there was a significant relationship between a greater number of anastomotic strictures and less use of a Kehr T-tube. In our series, there has been a decrease over the years in the number of surgical interventions required to resolve these complications and an increase in radiologic and endoscopic treatment.

RESUMO

INTRODUCTION: Patients with toxic substance abuse syndrome, such as alcohol abuse, have elevated psychopathologic morbidity and mortality such as mood disorders. OBJECTIVE: To evaluate the emotional-type psychopathologic symptoms in patients with alcohol-induced hepatic cirrhosis on the liver transplant waiting list. MATERIALS AND METHODS: Patients with alcoholic liver cirrhosis who were candidates for liver transplant (n = 41) completed the SA-45 questionnaire (González y Cuevas; 88), which assesses nine dimensions: somatizations, obsessive-compulsivity, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. A control group consisted of patients with chronic nonalcoholic terminal hepatopathies (n = 22). RESULTS: Seventy-six percent of patients had some kind of psychopathologic symptom compared to 68% of the patients in the control group with other nonalcoholic etiologies (P > .05). The emotional-type clinical symptoms were: (1) somatizations: 37% of patients with alcoholic cirrhosis had this type of clinical symptoms compared to 32% of the control group (P > .05); (2) obsessive-compulsivity: 56% versus 46%, respectively (P > .05); (3) interpersonal sensitivity: 19% versus 9%, respectively (P > .05); (4) depression: 54% versus 27%, respectively (P = .045); (5) anxiety: 59% versus 46%, respectively (P > .05); (6) hostility: 29% versus 5%, respectively (P = .021); (7) phobic anxiety: 10% versus 14%, respectively (P > .05); (8) paranoid Ideation: 7% versus 5%, respectively (P > .05); (9) psychoticism: 5% versus 4%, respectively (P > .05). CONCLUSIONS: The patients with alcoholic liver cirrhosis on the liver transplant waiting list had elevated psychopathologic symptoms. Depressive- and hostile-type emotional alterations were most frequent in this type of patients.

RESUMO

INTRODUCTION: T-tube removal in liver transplant patients can occasionally cause a massive biliary leak and may require surgical treatment for its resolution. We present our experience with a laparoscopic approach to biliary peritonitis in liver transplant patients after the removal of a T-tube. PATIENTS AND METHODS: From January 2003 until February 2010, we performed 351 liver transplantations in 313 recipients, including 135 with a T-tube. After its removal 31 biliary leaks developed (23%); 12 were massive and required surgery, which utilized a laparoscopic approach. RESULTS: The mean length of the intervention was 72.9 ± 12.87 minutes (range = 55-95), without any complications during the procedure, and no need to convert to a laparotomy. Mean hospital stay after the intervention was 6.75 ± 3.88 days (range 4-18). There was no mortality from the procedure. CONCLUSION: The laparoscopic approach for biliary leakage after T-tube removal is indicated when large diffuse acute peritonitis is established a few hours postremoval of the T-tube. This safe procedure treats the complication without the need for another laparotomy.

RESUMO

BACKGROUND: Transplant patients receiving immunosuppressant treatment suffer gastrointestinal symptoms (GIS) limiting their health-related quality of life (HRQOL) and causing dose redíuctions and discontinuations. METHODS: This observational, multicenter, cross-sectional study aims to develop and validate a questionnaire for detecting and quantifying the impact of GIS on the HRQOL of patients with functioning organ transplants. We developed a pilot version of the questionnaire SIGIT-QOL (Impact of Gastrointestinal Symptoms on Quality Of Life) and then evaluated the feasibility, validity, and reliability. We consecutively recruited 274 solid organ transplant patients from 20 hospitals. Sociodemographic and clinical data were collected. Patients completed the SIGIT-QOL and Gastrointestinal Quality of Life Index-GIQLI- questionnaires. RESULTS: Mean age was 52.7 (SD, 7.59) and 181 were male; 43.4% showed an episode of GIS since transplantation (3-12 months before). Of all patients, 95.3% completed the SIGIT-QOL. Mean time of completion was 6.49 minutes. Exploratory factorial analysis identified a 1-dimensional structure (42% of total variance). Internal consistency was high (Cronbach's alpha, 0.889). A significant association was found between the SGITI-QOL and the presence of GIS (P < .01). Finally, correlation coefficients between SIGIT-QOL and GIQLI were moderate-high except for Social Function. CONCLUSION: The brief SIGIT-QOL questionnaire can detect and quantify the GIS and their impact on the HRQOL of solid organ transplant patients.

RESUMO

Co-stimulatory factors such as CD86 and apoptotic molecules such as CD95 and CD95L required to start and to turn off the allogenic immune response may also be present as soluble proteins. To determine the role of the soluble forms of CD86 (sCD86), CD95 (sCD95) and CD95L (sCD95L) in the outcome of liver transplants, we analyzed the circulating levels of these molecules in patients subjected to liver transplantation in the pre-operative period and during the first month post-transplantation. Serum samples were obtained from sixty-nine first orthotopic liver transplants (OLT). The patients were classified into acute rejection (AR=24) and not acute rejection (NAR=45), or considering the presence of chronic active hepatitis B or C (VP=30) or other primary liver diseases (VN=39). The levels of sCD86, sCD95 and sCD95L were analyzed by solid phase sandwich enzyme-linked immunoabsorbent assays. Our results first showed that the pre-transplantation serum levels of sCD86 in the AR group were significantly higher than in the NAR group (1007±82U/mL vs. 739±46U/mL, p=0.006), and in the post-transplantation period these levels decreased sharply. Second, the levels of sCD95L and sCD95 in the pre-transplantation period did not point to statistically significant differences between the AR and NAR groups. Considering primary liver disease, the pre-transplantation levels of sCD86 and sCD95L in the VP group were significantly higher than those of the VN group (VP, 977±69U/mL vs. VN, 722±51U/mL, p<0.002, and VP, 482±78pg/mL vs. VN, 221±31pg/mL, p=0.002, respectively). Multivariate analysis revealed that only the pre-transplantation levels of sCD86 were independently associated with the development of episodes of acute rejection (p=0.005, OR=2.1, IC 95%=1.27-3.47). In conclusion, the present work shows that primary liver disease could influence the pre-transplantation levels of sCD86 and sCD95L. High pre-transplantation serum levels of sCD86 could favor the development of episodes of acute rejection.

RESUMO

INTRODUCTION: Liver transplantation is the treatment of choice for various types of end-stage liver disease and the most appropriate alternative for the treatment of hepatocellular carcinoma (HCC)-associated liver cirrhosis. The aim of this study was to describe our initial experience with the use of 18-FDG positron emission tomography (PET)/computed tomography CT before and after transarterial chemoembolization (TACE) in HCC patients undergoing liver transplantation, seeking to predict the percentage of tumor necrosis achieved by TACE procedures. PATIENTS AND METHODS: From January 2007 through December 2009, 39 patients with HCC and liver cirrhosis were included in our liver transplantation program. We selected the 6 subjects who underwent 18-fluorodeoxyglucose PET/CT (18-FDG PET/CT) pre- and post-TACE. RESULTS: The median SUV (standardized uptake value) in the lesions studied were 4 (range, 2.79-6.95) before TACE with a median post-TACE SUV of 0 (range, 0-4). Among patients whose post-TACE SUV decreased to <3, the percentage of necrosis after studying the hepatectomy was >80%. CONCLUSION: Performance of an 18-FDG PET/CT before and after TACE and comparison of SUV in patients with HCC awaiting liver transplantation provided valuable information regarding the effectiveness of TACE.

RESUMO

Central pontine myelinolysis (CPM) may be more prevalent after liver transplantation (OLT). Central pontine and extrapontine myelinolysis (CPEM) is rare. The occurence of CPM may be associated with hyponatremia, a rapid rise in serum sodium concentrations, postoperatively increased plasma osmolality, and the duration of the operation. Only 1 patient had abnormal sodium levels before LT. No abnormalities were detected in immunosuppressive drug blood levels. The aim of this paper was to report our experience with CPEM among LT patients.
