ABSTRACT

This cross sectional study was conducted in 2018 in Côte d'Ivoire to assess PrEP acceptability among men who have sex with men (MSM). Two hundred and one men were asked on their intention to use PrEP if made available. Logistic regression accounting for the sampling design was used to analyze associations between high PrEP acceptability and different independent variables including barriers and facilitators. Participants were mostly young (mean age = 25 years), educated (82% with secondary/postsecondary education) and single (95.5%). On average, 3.4 episodes of anal sex were reported monthly and 37.8% of men did not use a condom at last sex. Most MSM (72.6%) had heard of PrEP before enrollment. Overall, 35.3% reported that they would use PrEP very probably if made available. In multivariate analysis, factors associated with high PrEP acceptability were condom use at last sexual intercourse (Odds ratio (OR) = 2.51; 95%Confidence interval (95%CI) = 1.45-4.33); insertive sex as compared to versatile sex (OR = 2.56; 95%CI = 1.14-5.67); free PrEP delivery (OR = 2.45; 95%CI = 1.07-5.59), concerns about side effects (OR = 0.66; 95%CI = 0.48-0.90), and being preoccupied by the fact that post-PrEP antiretroviral therapy could be inefficient (OR = 0.25; 95%CI = 0.14-0.44). PrEP implementation among MSM in Côte d'Ivoire should be accompanied by awareness raising campaigns explaining its utility.

ABSTRACT

Many transplant centers use endoscopically directed brachytherapy to provide locoregional control in patients with otherwise incurable cholangiocarcinoma (CCA) who are awaiting liver transplantation (LT). The use of endoscopic retrograde cholangiopancreatography (ERCP)-directed photodynamic therapy (PDT) as an alternative to brachytherapy for providing locoregional control in this patient population has not been studied. The aim of this study was to report on our initial experience using ERCP-directed PDT to provide local control in patients with unresectable CCA who were awaiting LT. Patients with unresectable CCA who underwent protocol-driven neoadjuvant chemoradiation and ERCP-directed PDT with the intent of undergoing LT were reviewed. Four patients with confirmed or suspected CCA met the inclusion criteria for protocol LT. All four patients (100%) successfully underwent ERCP-directed PDT. All patients had chemoradiation dose delays, and two patients had recurrent cholangitis despite PDT. None of these patients had progressive locoregional disease or distant metastasis following PDT. All four patients (100%) underwent LT. Intention-to-treat disease-free survival was 75% at mean follow-up of 28.1 months. In summary, ERCP-directed PDT is a reasonably well tolerated and safe procedure that may have benefit by maintaining locoregional tumor control in patients with CCA who are awaiting LT.

ABSTRACT

Changes in organ allocation policy in 2002 reduced the number of adult patients on the liver transplant waiting list, changed the characteristics of transplant recipients and increased the number of patients receiving simultaneous liver-kidney transplantation (SLK). The number of liver transplants peaked in 2006 and declined marginally in 2007 and 2008. During this period, there was an increase in donor age, the Donor Risk Index, the number of candidates receiving MELD exception scores and the number of recipients with hepatocellular carcinoma. In contrast, there was a decrease in retransplantation rates, and the number of patients receiving grafts from either a living donor or from donation after cardiac death. The proportion of patients with severe obesity, diabetes and renal insufficiency increased during this period. Despite increases in donor and recipient risk factors, there was a trend towards better 1-year graft and patient survival between 1998 and 2007. Of major concern, however, were considerable regional variations in waiting time and posttransplant survival. The current status of liver transplantation in the United States between 1999 and 2008 was analyzed using SRTR data. In addition to a general summary, we have included a more detailed analysis of liver transplantation for hepatitis C, retransplantation and SLK transplantation.

ABSTRACT

As the outcomes of heart, liver, and lung transplantation continue to improve, more patients will present for subsequent renal transplantation. It remains unclear whether these patients benefit from induction immunosuppression. We retrospectively reviewed induction on solid organ graft recipients who underwent renal transplant at our center from January 1, 1995 to March 30, 2007. Induction and the non-induction groups were compared by univariate and Kaplan-Meier analyses. There were 21 patients in each group, with mean follow-up of 4.5-6.0 years. Forty-seven percent of patients receiving induction had a severe post-operative infection, compared with 28.6% in the non-induction group (p = NS). The one yr rejection rate in the induction group was 9.5% compared with 14.3% for non-induction (p = NS). One-yr graft survival was 81.0% and 95.2% in the induction and non-induction group (p = NS). In summary, there is a trend toward lower patient and graft survival among patients undergoing induction. These trends could relate to selection bias in the decision to prescribe induction immunosuppression, but further study is needed to better define the risks and benefits of antibody-induction regimens in this population.

ABSTRACT

Over the past several years we have noted a marked decrease in this profitability of our kidney transplant program. Our hypothesis is that this reduction in kidney transplant institutional profitability is related to aggressive donor and recipient practices. The study population included all adults with Medicare insurance who received a kidney transplant at our center between 1999 and 2005. Adopting the hospital perspective, multi-variate linear regression models to determine the independent effects of donor and recipient characteristics and era effects on total reimbursements and total hospital margin. We note statistically significant decreased medical center incremental margins in cases with ECDs (-$5887) and in cases of DGF (-4937). We also note an annual change in the medical center margin is independently associated with year and changes at a rate of -$5278 per year, related to both increasing costs and decreasing Medicare reimbursements. The financial loss associated with patient DGF and the use of ECD kidneys may resonate with other centers, and could hinder efforts to expand kidney transplantation within the United States. The Centers for Medicare and Medicaid Services (CMS) should consider risk-adjusted reimbursement for kidney transplantation.

ABSTRACT

Histidine-tryptophan-ketoglutarate (HTK) is replacing University of Wisconsin (UW) solution as the preservation fluid for renal allografts in many centers, but recent large-scale data to support this transition are lacking. We conducted a retrospective analysis of patient and graft outcomes after renal transplantation at our center, comparing 475 consecutive living donor and 317 deceased donor transplants since the adoption of HTK with equal numbers of grafts preserved using UW solution. Data collected included donor and recipient age, race, sex, comorbidities and graft ischemia time. Graft and patient survival, as well as the incidence of delayed graft function (DGF), were studied by Kaplan-Meier and Cox regression analysis. No significant difference was seen in either patient or graft survival. Deceased donor kidneys in the HTK group had a higher incidence of DGF than the UW cohort, whereas this trend was reversed in the case of living donor organs. In multivariate analysis, HTK was associated with a significant risk reduction on the incidence of DGF. Prolonged preservation with HTK compared to UW was not associated with excess risk to the graft or patient. In summary, HTK demonstrated efficacy similar to UW in terms of patient and graft survival.

ABSTRACT

We quantified the financial implications of surgical complications following pancreas transplantation. We reviewed medical and financial records of 49 pancreas transplant recipients at the University of Michigan Health System (UMHS) between 1/6/2002 and 11/22/2004. The association of donor, transplant recipient and financial variables was assessed. The median costs to UMHS of procedures and follow-up were $92,917 for recipients without surgical complications versus $108,431 when a surgical complication occurred, a difference of $15,514 (p = 0.03). Median reimbursement by the payer was $17,363 higher in patients with a surgical complication (p = 0.001). Similar trends (higher insurer costs) were noted when stratifying by payer (public and private) and specific procedure (SPK and PAK). All parties (patient, physician, payer and medical center) should benefit from quality improvement, with payers having a financial interest in pancreas transplant surgical quality initiatives.

ABSTRACT

Urinary complications are common following renal transplantation. The aim of this study is to evaluate the risk factors associated with renal transplant urinary complications. We collected data on 1698 consecutive renal transplants patients. The association of donor, transplant and recipient characteristics with urinary complications was assessed by univariable and multivariable Cox proportional hazards models, fitted to analyze time-to-event outcomes of urinary complications and graft failure. Urinary complications were observed in 105 (6.2%) recipients, with a 2.8% ureteral stricture rate, a 1.7% rate of leak and stricture, and a 1.6% rate of urine leaks. Seventy percent of these complications were definitively managed with a percutaneous intervention. Independent risk factors for a urinary complication included: male recipient, African American recipient, and the "U"-stitch technique. Ureteral stricture was an independent risk factor for graft loss, while urinary leak was not. Laparoscopic donor technique (compared to open living donor nephrectomy) was not associated with more urinary complications. Our data suggest that several patient characteristics are associated with an increased risk of a urinary complication. The U-stitch technique should not be used for the ureteral anastomosis.

ABSTRACT

The optimal use of kidneys from small pediatric deceased donors remains undetermined. Using data from the Scientific Registry of Transplant Recipients, 2886 small (< 21 kg) pediatric donors between 1993 and 2002 were identified. Donor factors predictive of kidney recovery and transplantation (1343 en bloc; 1600 single) were identified by logistic regression. Multivariable Cox regression was used to assess the risk of graft loss. The rate of kidney recovery from small pediatric donors was significantly higher with increasing age, weight and height. The odds of transplant of recovered small donor kidneys were significantly higher with increasing age, weight, height and en bloc recovery (adjusted odds ratio = 65.8 vs. single; p < 0.0001), and significantly lower with increasing creatinine. Compared to en bloc, solitary transplants had a 78% higher risk of graft loss (p < 0.0001). En bloc transplants had a similar graft survival to ideal donors (p = 0.45) while solitary transplants had an increased risk of graft loss (p < 0.0001). En bloc recovery of kidneys from small pediatric donors may result in the highest probability of transplantation. Although limited by the retrospective nature of the study, kidneys transplanted en bloc had a similar graft survival to ideal donors but may not maximize the number of successfully transplanted recipients.

ABSTRACT

The severity of illness in transplant patients and the complexity of transplant operations results in significant postoperative morbidity and mortality. Remarkable efforts have been made by transplant physicians to study and improve organ allocation, graft and patient survival, immunosuppression and the long-term management of post-transplant complications. Less effort has been spent studying the actual transplant operation and systems of acute transplant care. The National Surgical Quality Improvement Program (NSQIP) has provided a standardized approach to quality improvement and has demonstrated significant potential for a reduction in postoperative morbidity and mortality in other surgical disciplines. Medical centers are under increasing pressure to measure surgical quality and the nexus of transplant surgical quality improvement should not lie in the hands of CMS or JACHO, but rather it should be created and developed within the transplant community. The time has come for a national transplant surgical quality improvement program based on the NSQIP infrastructure. Such a proactive approach toward quality improvement from the transplant community is an excellent investment for patients, providers and health care payers.

ABSTRACT

We use biliary complication following liver transplantation to quantify the financial implications of surgical complications and make a case for surgical improvement initiatives as a sound financial investment. We reviewed the medical and financial records of all liver transplant patients at the UMHS between July 1, 2002 and June 30, 2005 (N = 256). The association of donor, transplant, recipient and financial data points was assessed using both univariable (Student's t-test, a chi-square and logistic regression) and multivariable (logistic regression) methods. UMHS made a profit of $6822 +/- 39087 on patients without a biliary complication while taking a loss of $5742 +/- 58242 on patients with a biliary complication (p = 0.04). Reimbursement by the payer was $5562 higher in patients with a biliary complication compared to patients without a biliary complication (p = 0.001). Using multivariable logistic regression analysis, the two independent risk factors for a negative margin included private insurance (compared to public) (OR 1.88, CI 1.10-3.24, p = 0.022) and biliary leak (OR = 2.09, CI 1.06-4.13, p = 0.034). These findings underscore the important impact of surgical complications on transplant finances. Medical centers have a financial interest in transplant surgical quality improvement, but payers have the most to gain with improved surgical outcomes.

ABSTRACT

Steroids are a mainstay in liver transplantation for induction and maintenance immunosuppression but are associated with significant adverse effects. While prior studies have successfully limited the use of steroids, whether complete steroid avoidance will improve outcomes remains unclear. To further evaluate the need for steroids, consenting patients who underwent liver transplantation between June 2002 and May 2004 were entered into a prospective, randomized trial to receive either standard therapy (tacrolimus, mycophenolate mofetil, steroid induction/maintenance) or complete steroid avoidance (standard therapy without steroid induction/maintenance). Clinically suspected rejection was confirmed by biopsy and treated with pulse steroid therapy. Outcomes were compared on an intention to treat basis. Of the 72 patients enrolled, 36 (50%) were randomized to the steroid avoidance group with a mean follow up of 412 +/- 41 days. Donor and recipient characteristics were similar between groups. The steroid avoidance group was more likely to have significant infections (52% vs 28%, P = .03). There was a trend toward an increased rate of acute rejection (25% vs 14%, P = .23). Twelve of 36 recipients (33%) enrolled in the steroid avoidance group later received steroids. The incidence of recurrent hepatitis C was similar between groups. The 1-year patient (90% vs 83%, P = .44) and graft survivals (90% vs 81%, P = .27) were similar between groups. These data suggest complete steroid avoidance in liver transplantation results in acceptable patient and graft survival. However, the potential long-term benefits of steroid avoidance, including a decrease in severity of recurrent hepatitis C, remain under investigation.

ABSTRACT

With the general aging of the United States population we can expect to encounter increasing numbers of elderly patients with surgical infections. To further delineate this population, patient attributes, treatment characteristics, and outcomes were examined in elderly patients with surgical infection. All infections from December 1996 through May 2000 occurring on the inpatient, adult general, and trauma surgical services at a university hospital were studied prospectively. Characteristics, comorbidities, and outcomes were examined in patients > or = 70 years of age and compared with those of patients <70 years of age. Elderly patients had significantly higher Acute Physiology and Chronic Health Evaluation (APACHE) II scores (15.4 +/- 0.3 vs 11.2 +/- 0.2, P < 0.001) and greater numbers of comorbidities than the younger population. The Acute Physiology score; infecting organisms; and rates of pneumonia and intra-abdominal, central line, and bloodstream infection were similar between groups. Crude mortality (21.7% vs 8.1%, P < 0.001) and mortality associated with pneumonia (31.0% vs 17.2%, P = 0.005), central venous catheter infection (50.0% vs 17.4%, P < 0.001), bloodstream infection (32.3% vs 16.6%, P = 0.006), and intra-abdominal infection (23.2% vs 6.3%, P < 0.001) were significantly higher in the elderly. Logistic regression analysis identified APACHE II score, cerebrovascular disease, and fungal infection as independent predictors of mortality in the elderly population. Surgical infection in the elderly is associated with a high mortality and requires special consideration when treating this unique population.

ABSTRACT

OBJECTIVE: The development of antibiotic-resistant bacteria is associated with significant morbidity and mortality in critically ill patients. We postulated that quarterly rotation of empirical antibiotics could decrease infectious complications from resistant organisms in an intensive care unit (ICU). DESIGN: Prospective cohort study. SETTING: An ICU at a university medical center. SUBJECTS: All patients admitted to the general, transplant, or trauma surgery services who developed pneumonia, peritonitis, or sepsis of unknown origin. INTERVENTIONS: A 2-yr study consisting of 1 yr of nonprotocol-driven antibiotic use and 1 yr of rotating empirical antibiotic assignment. MEASUREMENTS AND MAIN RESULTS: Over 100 variables were recorded for each infectious episode, including patient characteristics (e.g., Acute Physiology and Chronic Health Evaluation [APACHE] II score, age, comorbidities), infection characteristics (e.g., site, organism), treatment characteristics (e.g., antibiotic, treatment duration) and outcome measures (e.g., mortality, length of stay, antibiotic cost). Of 1456 consecutive admissions to the ICU, 540 episodes of infection were treated. No differences were noted in age, APACHE II score, race, overall antibiotic utilization or duration of therapy between the 2 yrs of study. Outcome analysis revealed significant reductions in the incidence of antibiotic-resistant Gram-positive coccal infections (7.8 infections/100 admissions vs. 14.6 infections/100 admissions, p <.0001), antibiotic-resistant Gram-negative bacillary infections (2.5 infections/100 admissions vs. 7.7 infections/100 admissions, p <.0001), and mortality associated with infection (2.9 deaths/100 admissions vs. 9.6 deaths/100 admissions, p <.0001) during rotation. Logistic regression identified age (odds ratio [OR], 1.03; 95% confidence interval [CI], 1.01-1.06), APACHE II score (OR, 1.06; 95% CI, 1.01-1.13), solid organ transplantation (OR, 9.50; 95% CI, 2.01-52.21), and malignancy (OR, 10.16; 95% CI, 4.11-26.96) as independent predictors of mortality. Antibiotic rotation was an independent predictor of survival (OR 6.27, 95% CI 2.78-14.16). CONCLUSION: Rotation of empirical antibiotic therapy seems to be a promising method to reduce infectious mortality in an ICU.

ABSTRACT

BACKGROUND: Hepatic artery thrombosis (HAT) is a significant cause of morbidity after liver transplantation. The aims of this study are to identify and compare risk factors that might contribute to HAT. METHODS: A total of 424 liver transplants performed at the University of Virginia were reviewed. HAT was defined as complete disruption of arterial blood flow to the allograft and was identified in 29 cases (6.8%). HAT was classified as early (less than 1 month posttransplant, 9 cases: 2.1%) or late (more than 1 month posttransplant, 20 cases: 5.4%). Possible risk factors for HAT were analyzed using Pearson chi2 test for univariate analysis and logistic regression for multivariate analysis. RESULTS: Multiple transplants, recipient/donor weight ratio >1.25, biopsy-proven rejection within 1 week of transplant, recipient negative cytomegalovirus (CMV) status, arterial anastomosis to an old conduit (defined as a previously constructed aorto-hepatic artery remnant using donor iliac artery), and CMV negative patients receiving allograft from CMV positive donors were found to be significant risk factors for developing early HAT. After logistic regression, factors independently predicting early HAT included arterial anastomosis to an old conduit [odds ratio (OR)=7.33], recipient/donor weight ratio >1.25 (OR=5.65), biopsy-proven rejection within 1 week posttransplant (OR=2.81), and donor positive and recipient negative CMV status (OR=2.66). Female donor, the combination of female donor and male recipient, recipient hepatitis C-related liver disease, donor negative CMV status, and the combination of recipient CMV negative and donor CMV negative were found to be significant risk factors for late HAT. Factors independently predicting late HAT by logistic regression included negative recipient and donor CMV status (OR=2.26) and the combination of a female donor and male recipient (OR=1.97). CONCLUSION: Therefore, in nonemergency situations attention to these factors in donor allocation may minimize the possibility of HAT.

ABSTRACT

OBJECTIVE: To assess the demographics and characteristics of infections in surgical patients to define areas that deserve emphasis in surgical education. SUMMARY BACKGROUND DATA: As a result of evolving technology and diseases, the complexity of diagnosing and treating infections has increased during the past three decades for all patients, including those treated primarily by surgeons. No comprehensive analysis of these conditions in a single surgical cohort has been recently published. METHODS: The authors conducted a prospective, observational study of all infections occurring on the general and trauma surgery services at a single university hospital during a 3.5-year period. RESULTS: The authors identified 2,457 infections: 608 community-acquired, 1,053 occurring on the wards, and 796 occurring in the intensive care unit. Although dependent on patient location, the most common sites were abdomen, lung, and wound; the most common isolates were Staphylococcus epidermidis, Staphylococcus aureus, and Candida albicans; and the most commonly used antibiotics were ciprofloxacin, vancomycin, and metronidazole. The overall death rate was 13%, ranging from 5% after community-acquired infections to 25% after infections acquired in the intensive care unit. CONCLUSIONS: Most infections treated by surgeons are hospital-acquired. Infections with gram-positive cocci and fungi are common, with pulmonary infections becoming more common. Fluoroquinolones have become important therapeutic agents. Depending on the type of practice, these data should be helpful to direct educational efforts so that surgeons can remain knowledgeable and active in the nonsurgical care of their patients.

ABSTRACT

Intra-abdominal infection continues to pose a significant threat to critically ill patients in the year 2000. A review of the current literature reveals that despite remarkable developments in critical care medicine and extensive study of patients with tertiary peritonitis, the associated mortality rate remains nearly 30%. Progress has been limited by the difficulty of comparing heterogeneous patient populations, groups that manifest a host of comorbid, potentially confounding illnesses. Additionally, debate persists regarding the definitions of secondary and tertiary peritonitis, resulting in varied study inclusion criteria, and further complicating data analysis and interpretation. Scoring systems developed to identify those patients at risk for progression to tertiary peritonitis, the more chronic, lethal form of intra-abdominal infection associated with multisystem organ failure, reflect the current emphasis in the literature on the importance of early diagnosis and early intervention. This has led to a renewed interest in conservative, data-dependent surgical management employing radiographic and microbiologic evidence to guide therapy.

ABSTRACT

The presence of fever and leukocytosis have traditionally been utilized as important diagnostic markers of infection despite some who question their reliability. To examine this point, the role of fever and leukocytosis as diagnostic and prognostic indicators for surgical infections was evaluated. A prospective observational study was performed on all patients with suspected infection in 1997 on the general surgical services at a university hospital. Fever was defined as maximum temperature (Tmax) > or = 38.5 degrees C, and leukocytosis was defined as a white blood cell (WBC) count > or = 11,000/microl. Among all infections, patients presenting with a Tmax > or = 38.5 degrees C were younger (51.3 +/- 1.1 vs. 53.8 +/- 0.9 years, p = 0.005) and had a higher APACHE II score (15.1 +/- 0.5 vs. 11.4 +/- 0.4; p < 0.001). By logistic regression analysis chronic renal insufficiency was associated with a Tmax < 38.5 degrees C [odds ratio (OR) 0.371, 95% confidence interval (CI) 0.195-0.704], and chronic steroid therapy was associated with a WBC count < 11,000/microl (OR 0.556, 95% CI 0.335-0.921). In addition, infected transplant patients were more likely to present with a Tmax < 38.5 degrees C and a WBC count < 11,000/microl (OR 0.195, 95% CI 0.075-0.502). Mortality rates for infected patients with a Tmax < 38.5 degrees C or > 38.5 degrees C were 11.6% and 12.9%, respectively (p < 0.7), and the lengths of stay were 14 +/- 1 and 18 +/- 1 days, respectively (p < 0.03). Mortality rates for patients with a WBC count < 11,000/microl or > 11,000/microl were 4.7% and 18.6%, respectively (p < 0.001), and the lengths of stay were 14 +/- 1 and 19 +/- 1 days, respectively (p < 0.001). In the setting of infection, chronic renal insufficiency and chronic steroid therapy are associated with suppression of fever and leukocytosis, respectively. Transplantation is an independent predictor of infection in patients presenting without fever or leukocytosis. Leukocytosis, but not fever, may be predictive of hospital mortality in infected surgical patients.

ABSTRACT

OBJECTIVE: To assess the importance of bloodstream infection (BSI) to outcomes among infected surgical patients. BACKGROUND: Bloodstream infection complicating infection is thought to connote a more serious condition compared with a primary infection alone. The authors recently reported, however, that BSI does not alter outcomes with central venous catheter colonization in the presence of sepsis. The significance of BSI with other infections has been incompletely evaluated. METHODS: Data on all episodes of infection among surgical patients were collected prospectively during a 38-month period at a single hospital, then analyzed retrospectively to determine the independent prognostic value of BSI for all infections by logistic regression analysis, and for abdominal infections and pneumonia using matched control groups. RESULTS: During the study period, 2,076 episodes of infection occurred, including 363 with BSI. Patients with BSI had a greater severity of illness and a greater death rate. After logistic regression, however, BSI did not independently predict death. After matching patients with abdominal infections and pneumonia with BSI to patients without BSI but with a similar site of infection, severity of illness, age, and causative organism, no difference in outcome was seen. CONCLUSIONS: Bloodstream infection is associated with critical illness and death but appears to be a marker of severe primary disease rather than an independent predictor of outcome.
