First birth from a deceased donor uterus in the United States: from severe graft rejection to successful cesarean delivery.

Uterus transplantation is the only known potential treatment for absolute uterine factor infertility. It offers a unique setting for the investigation of immunologic adaptations of pregnancy in the context of the pharmacologic-induced tolerance of solid organ transplants, thus providing valuable insights into the early maternal-fetal interface. Until recently, all live births resulting from uterus transplantation involved living donors, with only 1 prior birth from a deceased donor. The Cleveland Clinic clinical trial of uterus transplantation opened in 2015. In 2017, a 35 year old woman with congenital absence of the uterus was matched to a 24 year old parous deceased brain-dead donor. Transplantation of the uterus was performed with vaginal anastomosis and vascular anastomoses bilaterally from internal iliac vessels of the donor to the external iliac vessels of the recipient. Induction and maintenance immunosuppression were achieved and subsequently modified in anticipation of pregnancy 6 months after transplant. Prior to planned embryo transfer, ectocervical biopsy revealed ulceration and a significant diffuse, plasma cell-rich mixed inflammatory cell infiltrate, with histology interpreted as grade 3 rejection suspicious for an antibody-mediated component. Aggressive immunosuppressive regimen targeting both cellular and humoral rejection was initiated. After 3 months of treatment, there was no histologic evidence of rejection, and after 3 months from complete clearance of rejection, an uneventful embryo transfer was performed and a pregnancy was established. At 21 weeks, central placenta previa with accreta was diagnosed. A healthy neonate was delivered by cesarean hysterectomy at 34 weeks' gestation. In summary, this paper highlights the first live birth in North America resulting from a deceased donor uterus transplant. This achievement underscores the capacity of the transplanted uterus to recover from a severe, prolonged rejection and yet produce a viable neonate. This is the first delivery from our ongoing clinical trial in uterus transplantation, including the first reported incidence of severe mixed cellular/humoral rejection as well as the first reported placenta accreta.

Chronic laryngitis caused by Mycobacterium Kansasii in a traveler.

Chronic laryngitis commonly presents with dysphonia, and infectious causes include tuberculosis and endemic mycoses. We present a 58-year-old female with laryngitis for 5 years, fevers, chills, fatigue, malaise, myalgias, anterior neck pain, and night sweats after multicontinent exposure. Bronchoscopy cultures were negative. Bilateral microflap excision of vocal fold lesions demonstrated thickened epithelium and a deep vocal fold mass. Biopsy showed necrotizing granulomatous inflammation with acid-fast bacilli. Mycobacterium kansasii was identified. Treatment led to improvement in dysphonia, systemic symptoms, and vocal fold irritation. To our knowledge, this is the first case of isolated nontuberculous mycobacterial vocal fold infection.

Hypogammaglobulinemia and infection risk in solid organ transplant recipients.

PURPOSE OF REVIEW: Hypogammaglobulinemia may develop as a result of a number of immune deficiency syndromes that can be devastating. This review article explores the risk of infection associated with hypogammaglobulinemia in solid organ transplantation and discusses therapeutic strategies to alleviate such a risk. RECENT FINDINGS: Hypogammaglobulinemia is associated with increased risk of opportunistic infections, particularly during the 6-month posttransplant period when viral infections are most prevalent. The preemptive use of immunoglobulin replacement results in a significant reduction of opportunistic infections in patients with moderate and severe hypogammaglobulinemia. SUMMARY: Monitoring immunoglobulin G levels may aid in clinical management of solid organ transplant recipients. The preemptive use of immunoglobulin replacement may serve as a new strategy for managing solid organ transplant recipients with hypogammaglobulinemia.

Fatal West Nile Virus infection after rituximab/fludarabine--induced remission for non-Hodgkin's lymphoma.

West Nile virus (WNV) infections are potentially life threatening in immunocompromised hosts. Currently, the best diagnostic test is serology. Reverse-transcriptase polymerase chain reaction (RT-PCR) testing has a role, but, because WNV is a cell-associated neurotropic virus, RT-PCR results are frequently negative even in cases of active infection. We present a case in which serology results were persistently negative because the patient was immunocompromised following lymphoma treatment. The role of humoral immunity in resolution of WNV is also discussed.

Cell-mediated immune response to influenza vaccination in lung transplant recipients.

BACKGROUND: Lung transplant recipients are susceptible to complications from influenza infection. Antibody responses to influenza vaccination have been shown to be decreased in lung transplant recipients. Cellular immune mechanisms serve an important role in influenza clearance. The cellular immune response to influenza vaccination has not been studied in transplant populations. METHODS: Interleukin-2, interleukin-10, interferon-gamma, and granzyme B levels to the three viral antigens included in the 1999 to 2000 influenza vaccine were measured before and 4 weeks post-vaccination in 43 lung transplant recipients and 21 healthy adult controls. RESULTS: Interleukin-2, interleukin-10, interferon-gamma, and granzyme B levels did not increase from pre- to post-vaccination in the lung transplant group. Both pre- and post-cytokine levels were lower in the transplant group compared to the control group. Pre- and post-granzyme B levels did not differ significantly between the groups. The T-helper response in the control group varied with the different viral strains. A correlation between acute rejection episodes and the absence of both azathioprine and mycophenolate was found. CONCLUSIONS: Influenza vaccination does not stimulate a cell-mediated immune response in lung transplant recipients as judged by interleukin-2, interleukin-10, interferon-gamma, and granzyme B levels. Alternative prevention strategies may be needed.

Donor hepatitis-C seropositivity is an independent risk factor for the development of accelerated coronary vasculopathy and predicts outcome after cardiac transplantation.

BACKGROUND: It is possible, but unproven, that hepatitis C (HCV) infection accelerates atherosclerosis. We evaluated the hypothesis that donor HCV seropositivity predicts mortality and the development of coronary vasculopathy in cardiac transplant recipients. METHODS: Thirty-four cardiac transplant recipients who were seronegative for HCV at the time of transplantation received hearts from HCV-seropositive donors. We compared the mortality and the incidence of vasculopathy in this group of patients (study group) with a group of 183 successive heart transplant recipients (control group) with no evidence of HCV in the donor or in the recipient. RESULTS: After transplantation, 75% of the HCV-seronegative patients who received hearts from HCV-seropositive donors had detectable and persistent viremia (presence of HCV-RNA by reverse-transcription polymerase chain reaction). After a mean follow-up of 4.2 +/- 1.9 years, mortality was 2.8-fold greater in the study group than in controls (95% confidence interval [CI], 1.3-5.7; p = 0.006). The risk of having any vasculopathy after a mean follow-up of 3.4 +/- 1.6 years and after adjustment for other significant risk factors was 3-fold greater (hazards ratio, 3.08; 95% CI 1.52-6.20; p = 0.001) in the HCV group compared with controls. The risk of developing advanced vasculopathy was much greater in the study group compared with controls (hazard ratio, 9.4; 97% CI, 3.3-26.6; p = < 0.0001). The risk of mortality (p = 0.005) and vasculopathy (p = < 0.0001) was greatest in patients with combined donor HCV seropositivity and the presence of antibodies against donor B cells by flow cytometry. CONCLUSION: We conclude that donor hepatitis-C virus seropositivity is an independent risk factor for increased mortality and for the development of accelerated allograft vasculopathy after cardiac transplantation. These observations may have implications for the use of HCV-positive donors in heart transplant recipients.

Predictive value and cost-effectiveness analysis of a rapid polymerase chain reaction for preoperative detection of nasal carriage of Staphylococcus aureus.

OBJECTIVE: To determine the accuracy and cost-effectiveness of a polymerase chain reaction (PCR) for detecting nasal carriage of Staphylococcus aureus directly from clinical specimens. CROSS-SECTIONAL STUDY: This occurred in a tertiary-care hospital in Cleveland, Ohio, and included 239 consecutive patients who were scheduled for a cardiothoracic surgical procedure. Conventional cultures and a PCR for S. aureus from nasal swabs were used as measurements. COST-EFFECTIVENESS ANALYSIS: Data sources were market prices and Bureau of Labor Statistics. The time horizon was the maximum period for availability of culture results (3 days). Interventions included universal mupirocin therapy without testing; initial therapy, with termination if PCR negative (treat-PCR); initial therapy, with termination if culture negative (treat-culture); treat PCR-positive carriers (PCR-guided treatment); and treat culture-positive carriers (culture-guided treatment). The perspective was institutional and costs and the length of time to treatment were outcome measures. RESULTS: Sixty-seven (28%) of the 239 swabs grew S. aureus. Rapid PCR was 97.0% sensitive and 97.1% specific for the detection of S. aureus. For populations with prevalences of nasal S. aureus carriage of up to 50%, the PCR assay had negative predictive values of greater than 97%. PCR-guided treatment had the lowest incremental cost-effectiveness ratio (1.93 dollars per additional day compared with the culture strategy). Among immediate treatment strategies, treat-PCR was most cost-effective. The universal therapy strategy cost 38.19 dollars more per additional day gained with carrier identification compared with the PCR strategy. CONCLUSION: Rapid real-time PCR is an accurate, rapid, and cost-effective method for identifying S. aureus carriers for preoperative intervention.

A case of fatal West Nile virus meningoencephalitis associated with receipt of blood transfusions after open heart surgery.

First identified in the United States in 1999, West Nile virus caused approximately 3,500 infections in the late summer and fall of 2002. The virus is predominantly transmitted by mosquitoes, and the risk of infection through blood product transfusion is believed to be low. We present a case of West Nile virus encephalitis transmitted by red blood cell transfusion at the time of coronary artery bypass grafting that resulted in the patient's death. Individuals undergoing procedures with high blood product transfusion requirements, such as cardiac surgery or organ transplantation, may be at higher risk of this nosocomial infection during epidemics.

Topical vapocoolant quickly and effectively reduces vaccine-associated pain: results of a randomized, single-blinded, placebo-controlled study.

BACKGROUND: Comprehensive international travel preparation often requires several vaccines. Up to 90% of adults have some fear of injections, mostly due to injection-related pain. Pediatric studies with routine vaccines have shown topical anesthetic EMLA cream (lidocaine and prilocaine, Astra Pharmaceuticals, Inc.) and the topical vapocoolant Fluori-Methane (dichlorodifluoromethane and trichlorodifluoromethane, Gebauer Co.) to be equally effective in reducing pain from vaccinations. EMLA cream is expensive and requires a 60-min application, while Fluori-Methane (FM) is immediate in onset of action and inexpensive. Skin anesthesia begins at 10 degrees C. Fluori-Methane can briefly cool the skin to 0 degrees C. METHODS: We studied the effectiveness of topical vapocoolant on adult clients at our international travel clinic in a randomized, controlled trial of topical FM vs. cold (4 degrees C) saline placebo. Using a preset randomization table, participants served as their own controls, receiving placebo/control or active agent (participant blinded) in one arm (left or right), and a similar number of vaccines in the untreated arm. Vaccines were administered according to a set protocol per arm to minimize the risk of bias. Pain was measured using a modified McGill present pain intensity (PPI) pain index. Subjects rated their pain immediately and at 5 min on a six-level scale, noting treated and untreated arms separately. A questionnaire was completed on intervention preferences. Sample size was predetermined to achieve 90% statistical power estimating 25% efficacy (minimum n=172). RESULTS: One hundred and eighty-five participants were enrolled; 93 FM and 92 cold saline placebo. FM-treated arms had a significant reduction in immediate pain compared to untreated arms (pain scale mean 2.2 vs. 3.1; p<.0001), and compared to placebo (mean 2.2 vs. 2.8; p<.01). Delayed pain at 5 min was not affected by FM or control (mean 1.9 vs. 2.0) compared to no intervention (pain scale 1.9). The intervention preference questionnaire indicated that participants did not find FM therapy uncomfortable. They would choose FM therapy in the future, over a cream, especially if a wait was involved. CONCLUSION: The topical vapocoolant Fluori-Methane is an effective, quick, preferred, inexpensive agent for reducing vaccine-associated injection pain for international travel clients.

Selecting suitable solid organ transplant donors: Reducing the risk of donor-transmitted infections.

Selection of the appropriate donor is essential to a successful allograft recipient outcome for solid organ transplantation. Multiple infectious diseases have been transmitted from the donor to the recipient via transplantation. Donor-transmitted infections cause increased morbidity and mortality to the recipient. In recent years, a series of high-profile transmissions of infections have occurred in organ recipients prompting increased attention on the process of improving the selection of an appropriate donor that balances the shortage of needed allografts with an approach that mitigates the risk of donor-transmitted infection to the recipient. Important advances focused on improving donor screening diagnostics, using previously excluded high-risk donors, and individualizing the selection of allografts to recipients based on their prior infection history are serving to increase the donor pool and improve outcomes after transplant. This article serves to review the relevant literature surrounding this topic and to provide a suggested approach to the selection of an appropriate solid organ transplant donor.

Staphylococcus aureus bacteremia in solid organ transplant recipients: evidence for improved survival when compared with nontransplant patients.

BACKGROUND: Staphylococcus aureus bacteremia (SAB) is an important cause of morbidity and mortality. Herein, we describe the incidence, clinical characteristics, and outcomes of SAB after solid organ transplantation (SOT) and compare these features with non-SOT controls. METHODS: In a single-center retrospective study, blood cultures positive for S. aureus were obtained from January 1, 2000, to December 31, 2008. Chart review was performed on all SOT recipients with SAB. The social security death index was used to determine all-cause mortality. RESULTS: Seventy of 2959 patients with SAB were SOT recipients (26 lung, 19 liver, 18 kidney, and seven heart). The overall attack rate of SAB in SOT was 22.9/1000 transplant patients. Early-onset SAB (≤ 90 days) was more frequent in liver recipients (79%), when compared with kidney recipients (17%). All-cause 30-day and 1-year mortality rates were 6% and 28% in SOT, respectively. Pneumonia as a source was associated with an increased 30-day mortality (18% vs. 2%, P = 0.04). Comparing SOT versus non-SOT controls, methicillin resistance was more frequent (86% vs. 52%, P < 0.0001), and duration of bacteremia was longer (mean 3.8 vs. 1.6 days, P < 0.01). SOT status was independently associated with lower risk of 30-day mortality (risk ratio [RR]: 0.37, P = 0.02). CONCLUSIONS: In our cohort of SOT recipients, SAB was less common than previously reported and surprisingly had lower 30-day mortality, when compared with non-SOT. In SOT recipients, pneumonia as a source of SAB in SOT is associated with an increased 30-day mortality.

Utility of leflunomide in the treatment of complex cytomegalovirus syndromes.

BACKGROUND: Cytomegalovirus (CMV) viremia that is resistant or refractory to the standard antiviral therapy still constitutes a major threat to high-risk transplant recipients. In addition, multiple CMV recurrences may lead to neutropenia because of repeated courses of therapy with ganciclovir derivatives. Leflunomide, a drug for rheumatoid arthritis, has been reported to have anti-CMV activity. This study reports on its use in 17 transplant recipients with complex CMV syndromes who had failed or were intolerant to other therapies. METHODS: Single-center, retrospective study. Clinical data were extracted from the electronic medical record. CMV DNA viral loads were performed by quantitative hybrid capture assay. RESULTS: Leflunomide was initiated after a median of three episodes of CMV viremia, with a mean peak viral load of 245,826 copies/mL. Initial clearance of CMV viremia was observed in 14 of 17 patients (82%), and 9 of 17 (53%) patients achieved a long-term suppression of CMV recurrences. Higher peak viral load and higher viral load at the start of leflunomide therapy were associated with failure to suppress viremia. The duration of leflunomide therapy ranged from 1 to 24 months (median 3.5 months, interquartile range 2.6-7 months), and the mean time to an undetectable CMV-DNA was 1.9 months. Adverse effects included diarrhea (35%), anemia (18%), and increased liver function tests (12%). CONCLUSIONS: Leflunomide, alone or in combination, has potential utility in treatment of complex CMV syndromes and in long-term suppression of viremia. The optimal duration of therapy and the balance of risks and benefits are not yet known.

Can donors with prior hepatitis be safely used for heart transplantation?

BACKGROUND: Heart transplantation represents a significant life-saving and increased quality-of-life intervention for patients with refractory cardiac failure. Successful transplantation requires continuous immunosuppression to avoid immune rejection. Unfortunately, persistent viral infections in donors may be transmitted to recipients in the process of heart transplantation. With the severe shortage of available organs and significant waiting list mortality there is a rationale for considering use of organs from donors with evidence of prior hepatitis B and/or hepatitis C infection. METHODS: Published literature articles were searched using Medline, PaperChase and further review of references in relevant articles on issues related to hepatitis B and hepatitis C and heart transplantation. RESULTS: Donor and recipient testing for hepatitis B and hepatitis C is important for relative risk assessment. Nucleic acid testing for hepatitis B DNA and hepatitis C RNA represent emerging technologies, which may add valuable information to traditional serologic testing. CONCLUSIONS: Heart transplant recipient risk may be modified by vaccination against hepatitis B before transplantation. There is currently no available vaccine for hepatitis C. Recently described effective treatments for hepatitis B and hepatitis C provide further rationale for reconsideration of using hearts from donors with evidence of hepatitis B and/or hepatitis C infection.

The impact of hypogammaglobulinemia on infection outcome in patients undergoing ventricular assist device implantation.

BACKGROUND: Infection is a major comorbidity after ventricular assist device (VAD) placement. Defects in cellular immunity have been reported after VAD placement. However, to our knowledge, quantitative immunoglobulin G (IgG) level determination and the impact of hypogammaglobulinemia (HGG) on infections after VAD implantation have not been evaluated before. METHODS: A total of 76 patients (mean age, 53 years) underwent VAD implantation as a bridge to transplantation and had IgG levels determined as a baseline before transplantation. Patients were divided into 2 groups according to IgG level: Control Group (n = 56, IgG > or = 700 mg/dl) and HGG Group (n = 20, IgG < 700 mg/dl). Infection outcome during the VAD course and after transplantation was analyzed in relation to the IgG level. RESULTS: Baseline characteristics were similar in both groups. The incidence of bacteremia (14/20 [70%] vs 18/56 [32%], p = 0.0032) and major infection (19/20 [95%] vs 31/56 [56%], p = 0.0009) were significantly increased in the HGG Group compared with the Control Group. After transplantation, the episodes of rejection were similar in both groups and survival was similar. The HGG Group experienced more cytomegalovirus infections compared with the Control Group (9/20 [45%] vs 9/56 [16%], p = 0.009). CONCLUSIONS: VAD patients with HGG are at increased risk of infections. After transplantation, these patients also experience increased cytomegalovirus infections. A randomized preemptive IgG replacement trial may be warranted in the future to determine if this intervention will alleviate the risk of infection.

Donor or recipient hepatitis B seropositivity is associated with allograft vasculopathy.

BACKGROUND: Increasing interest has focused on possible viral triggers of cardiac allograft vasculopathy. Although much interest has centered on cytomegalovirus, it has recently been noted that donor hepatitis C seropositivity is associated with risk for accelerated vasculopathy. The current study hypothesized that hepatitis B (HBV) might be associated with accelerated vasculopathy. METHODS: Sixty-six patients who received heart transplants between September 1998 and July 2000 were analyzed by intravascular ultrasound within 6 weeks and again at 12 months after transplantation. These patients were divided into 2 groups: the HBV Group (n = 13) in which either the donor or recipient was seropositive for hepatitis B core antibody (HBcAb), and a Control Group (n = 53) in which neither donor nor recipient was positive for HBcAb. RESULTS: Baseline characteristics of the 2 groups were similar. The HBV Group had significant increase in the change in average intimal area (1.59 +/- 1.4 vs 0.46 +/- 0.4 mm2, p = 0.01) per mm length of the vessel compared with controls. Allograft vasculopathy at 1 year (defined as largest maximal intimal thickness increase of > or =0.50 mm) occurred in 46% of the HBV group compared with 24% of the control group (p = 0.05). When measured as an average maximal intimal thickness increase of >0.30 mm, allograft vasculopathy at 1 year occurred in 31% of the HBV Group compared with 5% of Controls (p = 0.01). CONCLUSIONS: These preliminary results suggest that HBV seropositivity in donor or recipient may be associated with an increased risk for cardiac allograft vasculopathy.

The role of swab and tissue culture in the diagnosis of implantable cardiac device infection.

BACKGROUND: The isolation of a pathogen is vital in the diagnosis and treatment of a device infection. A swab culture, despite poor sensitivity, is the most common method used in specimen collection. OBJECTIVE: To determine the relative value of swab and tissue specimen cultures in patients with implantable cardiac pacemakers and defibrillators. DESIGN: Prospective patient cohort study. SETTING: A 1,000-bed tertiary referral center in Cleveland, Ohio. PATIENTS: Consecutive patients with implantable cardiac pacemaker or defibrillator presenting for lead extraction from October 1, 2000 to March 31, 2001. METHODS: Tissue and swab cultures were prospectively collected during pacemaker and implantable defibrillator surgeries that required lead extraction. Clinical manifestations, microbiology, and echocardiographic data were recorded in patients with and without a clinical diagnosis of device system infection. RESULTS: Seventy-one patients with implantable pacemaker (n = 49, 69%), implantable defibrillator (n = 18, 25%), or both devices (n = 4, 6%) requiring lead extraction had pocket swab and tissue cultures for analysis. Infection was evident clinically in 35 (49%) of the patients and absent in the remainder. The most common bacteria isolated were coagulase-negative Staphylococcus (37%) and Staphylococcus aureus (10%). Patients with clinical infection had positive cultures more frequently (P = 0.002) by pocket tissue culture (n = 24, 69%) than by swab culture (n = 11, 31%). However, patients without clinical infections had positive cultures at similar rates by pocket tissue culture (n = 10, 28%) and by swab culture (n = 8, 22%; P = 0.48). Patients without clinical infection were not treated with other than perioperative antibiotics, and did not develop clinical infections. CONCLUSION: Pocket tissue cultures are more effective than pocket swab cultures for the isolation and identification of the infectious pathogens in cardiac device infections. Positive cultures by pocket swab or tissue cultures in the absence of clinical signs and symptoms of infection does not imply infection or the need for specific therapy.

The impact of CytoGam on cardiac transplant recipients with moderate hypogammaglobulinemia: a randomized single-center study.

BACKGROUND: We have previously shown that the preemptive use of cytomegalovirus (CMV) immunoglobulin (Ig) replacement (CytoGam) decreases the incidence of opportunistic infections in cardiac transplant recipients with severe hypogammaglobulinemia. However, the impact of Ig replacement in moderately hypogammaglobulinemic patients is unknown. METHODS: Periodic monitoring of the IgG levels was done in 300 heart transplant recipients. Moderate hypogammaglobulinemia (IgG, 350-500 mg/dl) developed in 56 patients (18.6%). Thirty-three patients declined randomization but agreed to have their IgG levels monitored. Twenty-three patients were randomized to placebo (n = 10) or CytoGam (n = 13) at 105 +/- 63 days after transplantation. RESULTS: The baseline characteristics were similar. A significant reduction in CMV infection was noted in the CytoGam Group compared with the Placebo Group (15.4% [2/13] vs 60% [6/10], p = .039). Among patients who declined randomization, CMV infection developed in 13 (39.4%) of 33, and 6 (46.1%) of the 13 progressed to severe hypogammaglobulinemia. A trend for reduction in the average episodes of > or =grade 2 rejection during the 6-month period after randomization was noted in the CytoGam group (0.4 +/- 0.6 vs 1.4 +/- 1.3, p = 0.065). CONCLUSIONS: The preemptive use of CytoGam decreases the incidence of CMV infection in patients with moderate hypogammaglobulinemia. A larger randomized study is needed to substantiate these results.
