Abstract
Infection management in solid organ transplantation poses unique challenges, with a diverse array of potential pathogens and associated antimicrobial therapies. With limited high-quality randomized clinical trials to direct optimal care, therapeutic "myths" may propagate and contribute to suboptimal or excessive antimicrobial use. We discuss 6 therapeutic myths with particular relevance to solid organ transplantation and provide recommendations for infectious diseases clinicians involved in the care of this high-risk population.

Secondary antibody deficiency is associated with development of infection in kidney transplantation: Results of a multicenter study. Transpl Infect Dis 2020; 23:e13494. [PMID: 33064917 DOI: 10.1111/tid.13494] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Revised: 09/22/2020] [Accepted: 10/11/2020] [Indexed: 12/28/2022]
Abstract
BACKGROUND We performed a multicenter study to assess the association between secondary antibody deficiency (immunoglobulin G [IgG] hypogammaglobulinemia combined with low levels of specific antibodies) and development of infection in kidney transplantation. METHODS We prospectively analyzed 250 adult kidney recipients at four centers. The assessment points were before transplantation and 7 and 30 days after transplantation. The immune parameters were as follows: IgG, IgA, and IgM and complement factors C3 and C4 tested by nephelometry; specific IgG antibodies to cytomegalovirus (CMV) and IgG and IgG2 antibodies to pneumococcal polysaccharide (anti-PPS) determined using enzyme-linked immunosorbent assay. The clinical follow-up period lasted 6 months. The clinical outcomes were CMV disease and recurrent bacterial infections requiring antimicrobial therapy. STATISTICS Multivariate logistic regression. RESULTS At day 7, IgG hypogammaglobulinemia (IgG levels < 700 mg/dL) combined with low IgG anti-CMV antibody titers (defined as levels < 10 000 units) was present in 12% of kidney recipients. IgG hypogammaglobulinemia combined with low IgG anti-PPS antibody titers (defined as levels < 10 mg/dL) at 1 month after kidney transplantation were recorded in 16% of patients. At day 7 the combination of IgG hypogammaglobulinemia and low anti-CMV titers was independently associated with the development of CMV disease (odds ratio [OR], 6.95; 95% confidence interval [CI], 1.17-41.31; P = .033). At day 30 after transplantation, the combination of IgG < 700 mg/dL and IgG anti-PPS < 10 mg/dL, was independently associated with recurrent bacterial infection (OR, 5.942; 95% CI, 1.943-18.172; P = .002). CONCLUSION In a prospective multicenter study, early immunologic monitoring of secondary antibody deficiency proved useful for the identification of kidney recipients who developed severe infection.

Antibiotics versus no therapy in kidney transplant recipients with asymptomatic bacteriuria (BiRT): a pragmatic, multicentre, randomized, controlled trial. Clin Microbiol Infect 2020; 27:398-405. [PMID: 32919076 DOI: 10.1016/j.cmi.2020.09.005] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 08/30/2020] [Accepted: 09/01/2020] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Many transplant physicians screen for and treat asymptomatic bacteriuria (ASB) during post-kidney-transplant surveillance. We investigated whether antibiotics are effective in reducing the occurrence of symptomatic urinary tract infection (UTI) in kidney transplant recipients with ASB. METHODS We performed this multicentre, randomized, open-label trial in kidney transplant recipients who had ASB and were ≥2 months post-transplantation. We randomly assigned participants to receive antibiotics or no therapy. The primary outcome was the incidence of symptomatic UTI over the subsequent 12 months. RESULTS One hundred and ninety-nine kidney transplant recipients with ASB were randomly assigned to antibiotics (100 participants) or no therapy (99 participants). There was no significant difference in the occurrence of symptomatic UTI between the antibiotic and no-therapy groups (27%, 27/100 versus 31%, 31/99; univariate Cox model: hazard ratio 0.83, 95%CI: 0.50-1.40; log-rank test: p 0.49). Over the 1-year study period, antibiotic use was five times higher in the antibiotic group than in the no-therapy group (30 antibiotic days/participant, interquartile range 20-41, versus 6, interquartile range 0-15, p < 0.001). Overall, 155/199 participants (78%) had at least one further episode of bacteriuria during the follow-up. Compared with the participant's baseline episode of ASB, the second episode of bacteriuria was more frequently caused by bacteria resistant to clinically relevant antibiotics (ciprofloxacin, cotrimoxazole, third-generation cephalosporin) in the antibiotic group than in the no-therapy group (18%, 13/72 versus 4%, 3/83, p 0.003). CONCLUSIONS Applying a screen-and-treat strategy for ASB does not reduce the occurrence of symptomatic UTI in kidney transplant recipients who are more than 2 months post-transplantation. Furthermore, this strategy increases antibiotic use and promotes the emergence of resistant organisms.

Abstract
The emerging field of vascular composite allotransplantation (VCA) has become a clinical reality. Building upon cutting edge understandings of transplant surgery and immunology, complex grafts such as hands and faces can now be transplanted with success. Many of the challenges that have historically been limiting factors in transplantation, such as rejection and the morbidity of immunosuppression, remain challenges in VCA. Because of the accessibility of most VCA grafts, and the highly immunogenic nature of the skin in particular, VCA has become the focal point for cross-disciplinary approaches to developing novel approaches for some of the most challenging immunological problems in transplantation, particularly the early diagnoses and assessment of rejection. This paper provides a historically oriented introduction to the field of organ transplantation and the evolution of VCA.

Abstract
BACKGROUND Neurologic complications occur in about 30% of renal transplant patients, infections being the most common. We encountered three such patients and present our experience in the management of such cases. CLINICAL MATERIAL Three cases of brain abscess in renal transplant recipients are reported. These patients presented from 9-60 months after the transplant. One patient had a pyogenic abscess; in the second the organism identified was Nocardia asteroides; in the third, a fungal infection was responsible. In two patients excision of the abscess was done, while in one repeated aspirations with intracavitary antibiotics were used. All received systemic antimicrobial therapy. CONCLUSIONS Central nervous system (CNS) complications, specifically infections, are quite common in renal transplant recipients, but reports of brain abscesses in these patients are very rare. The treatment options for such patients are discussed.

Abstract
Over the last ten to fifteen years medical and surgical advances have led to lower rates of infection and infection-related mortality in transplant recipients. Despite these advances, the process whereby one diagnoses and manages infectious problems in transplant patients has become increasingly complex. Evaluation of transplant patients with infections requires a good understanding of the intricacies of modern immunosuppressive therapy and both the typical and atypical clinical manifestations of many conventional and opportunistic pathogens. In particular, it is incumbent upon the clinicians caring for transplant patients to be familiar with the biology of cytomegalovirus and other herpes viruses, and of the prophylactic strategies that have evolved to lessen the burden of disease from these agents. Thorough knowledge is also required of common fungal pathogens and the viruses that cause chronic hepatitis. Transplant patients also should always be evaluated in the temporal context of their transplant operation, because different diseases are prevalent at different times after transplantation. Since immunosuppressive drugs modify the clinical presentation of infections is important to maintain clinical vigilance and attend to even minor new symptoms. This chapter is designed to provide a relatively concise overview of transplant infections for intensivists or other clinicians who encounter transplant patients in their practice. The references encompass much of the classic transplant infectious disease literature; they are included, not only for citation, but as a bibliography for further study.

Abstract
Table 6 is a summary of the organisms discussed with a listing of the environmental source, the endogenous source, the predisposing factors including neoplasms, and the postulated mechanisms by which the organism can gain access to the circulation. The evidence considered indicates that the entrance of one of these microorganisms into the bloodstream of a human being depends on the presence of multiplicity of predisposing factors. In the majority of cases of bacteremia due to one of these unusual organisms, two or more predisposing factors are present. Certain predisposing factors, such as cancer chemotherapy or intravenous catheterization, often provide a barrier break, while others, such as liver disease, may render the host immune system less capable of clearing organisms from the circulation. For organisms such as Campy-lobacter, Listeria, and Salmonella spp., attributes that allow the invasion of a healthy host are present and seem to be enhanced by the simultaneous presence of a predisposing condition, such as liver disease, in the host. Although somewhat fragmentary, a number of individual case reports describe bacteremia due to one of these organisms occurring weeks to years after surgery and after other therapeutic measures had effected a supposed cure of a cancer. It may be speculated that cancer patients, even after a cure, are still susceptible to bloodstream invasion by one of the aforementioned organisms by virtue of the presence of one or more predisposing metabolic, physiologic, or immunologic factors, even though these factors may be cryptic. The predominance of hematologic malignancies among cases of bacteremia due to these unusual organisms is also apparent. Although, as pointed out by Keusch (169), the reduction in the performance of immune function in hematologic malignancies compared with solid tumors is likely to be responsible, other associations of certain organisms with specific neoplasms warrant further examination. The frequency of bloodstream infections of Salmonella typhimurium and Capno-cytophaga canimorsus in Hodgkin's disease patients seems likely due to a particular mechanism which infection by these species is favored. The specific nature of these mechanisms remains to be determined. The recovery of any unusual bacterium from blood should warrant a careful consideration of the possibility of underlying disease, especially cancer. Microbiologists should advise clinicians of the unusual nature of the identified organism and provide the counsel that certain neoplastic processes, often accompanied by neutropenia, render the human host susceptible to invasion by almost any bacterium. The recovery of such organisms as C. septicum or S. bovis should prompt the clinician to aggressively seek to identify an occult neoplasm if one has not yet been diagnosed.

Abstract
Immunosuppressed prematures, cancer patients, and transplant recipients are susceptible to bacterial or fungal sepsis or both. This report evaluates whether the ability of the reticuloendothelial system (RES) to remove blood-borne viable radiolabeled 35S Escherichia coli and 3H-Leucine Candida albicans is adversely affected by a dual intravenous challenge of these organisms. Male Sprague Dawley rats (n = 150) weighing 175 to 180 g were placed in 5 experimental groups (n = 30). Group I received intravenous (IV) C albicans (10(7)/mL), group II received E coli (10(9)/mL), group III received a dual injection of C albicans and E coli, group IV received Candida 1 hour prior to E coli, and group V received E coli 1 hour prior to fungi. At 1, 4, and 24 hours, tissue samples (50 to 100 mg) of liver, spleen, kidneys, and lungs were processed for liquid scintillation counting. Organ distribution of bacteria and fungi was calculated and expressed as mean percent +/- SD of labeled organisms. The liver trapped 72% +/- 10% and the lungs 1.1% +/- 0.3% of E coli (group II) (P < .001). The organ distribution of Candida (group I), however, was similar in liver and lungs (42.5% +/- 10% and 41.4% +/- 6.4%, respectively). Liver localization of E coli was unaffected by simultaneous or staggered fungal injection (groups III, 4, and V). Lung distribution of E coli following dual injection (group III) was significantly higher than controls (group II) (3.6% +/- 0.7% v 1.1% +/- 0.3%; P < .001).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
PURPOSE To determine the efficacy of long-term prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMZ) for prevention of bacterial infection following renal transplantation, the absorption of TMP-SMZ in transplant patients, the effects of prophylaxis on the microflora, and the cost-benefit of prophylaxis. PATIENTS AND METHODS One hundred thirty-two adult patients selected to undergo renal transplantation participated in a randomized, double-blind, placebo-controlled trial. RESULTS Patients randomized to receive TMP-SMZ experienced fewer hospital days with fever (3.3% versus 7.7%, p less than 0.001) and significantly fewer bacterial infections during the transplant hospitalization after removal of a urethral catheter (0.76 versus 1.88 per 100 days, p less than 0.005) and following discharge from the hospital (0.08 versus 0.30 per 100 days, p less than 0.001). During the transplant hospitalization, a daily dose of 320/1,600 mg was highly effective for prophylaxis whereas 160/800 mg daily gave unexpectedly low blood levels and was effective only for prevention of urinary tract infections after catheter removal. Prophylaxis was most effective in prevention of infections of the urinary tract (24 versus 54, p less than 0.005) and bloodstream (one versus nine, p less than 0.01) and infections caused by enteric gram-negative bacilli (four versus 46, p less than 0.001), enterococci (six versus 22, p = 0.006), or Staphylococcus aureus (one versus nine, p = 0.01). Prophylaxis did not prevent urinary tract infection associated with urethral catheters in the early posttransplant period, but after catheter removal, reduced the risk of urinary tract infection threefold (p less than 0.001). No significant differences in colonization by TMP-SMZ-resistant gram-negative bacilli were identified between the two groups; patients given TMP-SMZ were, paradoxically, less likely to become colonized by candida, probably because of less exposure to antibiotics for treatment of infection. Recipients of prophylaxis did not have a higher rate of infection caused by TMP-SMZ-resistant bacteria or Candida; however, their infections were more likely to be caused by resistant bacteria than infections in patients in the placebo group (62% versus 18%, p less than 0.001). CONCLUSIONS Prophylaxis with TMP-SMZ, which is well tolerated, significantly reduces the incidence of bacterial infection following renal transplantation, especially infection of the urinary tract and bloodstream, can provide protection against Pneumocystis carinii pneumonia, and is cost-beneficial. Subnormal absorption of TMP-SMZ in the early posttransplant period mandates 320/1,600 mg daily for optimal benefit. Prophylaxis has little discernible effect on the microflora.

Abstract
Tuberculosis (TB) was diagnosed in 25 of 466 patients who underwent renal transplant over a period of 15 years. TB developed from 1 month to 9 years post-transplant. In 56% of the cases the onset was within the first post-transplant year. TB affected several isolated or combined organs. Pulmonary involvement was present in 76% of cases, either as isolated pleuro-pulmonary (56%) or associated with other sites (20%). The non-pulmonary sites were: skin, joints, tests, urinary tract, central nervous system and lymphonodules. The diagnosis was confirmed by biopsy in 64% of the cases, by identification of tubercle bacilli in 24% and only at necropsy in 12% Biopsy specimens could be classified in three histological forms: exudative, that occurred in early onset and more severe cases granulomatous in late onset and benign cases; and mixed in intermediate cases. Azathioprine dosages were similar along post-transplant time periods in TB patients and in the control groups; and in TB patients who were cured and who died. The number of steroid treated rejection crises was greater in TB than in the control group. Prednisone doses were higher and the number of rejection crises was greater in TB patients who died than in those who were cured. Fifteen patients were cured and ten died, two of them of causes unrelated to TB. Six of the eight TB-related deaths occurred in the first 6 post-transplant months. The outcome was poor in patients in whom TB arose early in post-transplant period and where the exudative or mixed forms were present; whereas the prognosis was good in patients with late onset and granulomatous form of TB. In one patient TB was transmitted by the allograft.

Abstract
Infectious complications in the renal transplant patient are common, and infecting agents include opportunistic organisms as well as common pathogens. However, we were only able to document 6 patients who had septic arthritis from more than 800 who received a renal transplant at our institution over an 18-year period. Furthermore, only 16 other cases of infectious arthritis have been reported in the literature. All of our patients had an apparent predisposing factor and 3 patients had prior infection with the same organism. The knee was the most commonly infected joint. The initial synovial fluid white blood cell count was usually greater than 30,000 cells/mm3, but 1 patient with viral arthritis initially had noninflammatory fluid. The peripheral blood white blood cell count may not be elevated. All of our cases of initial joint infection occurred by 18 months posttransplant. Blood cultures were positive in 3 of 4 patients with bacterial infection. Followup of these 6 patients averaged 4.3 years. Numerous other rheumatologic syndromes and disorders peculiar to the posttransplant period may mimic a septic joint. Consequently, despite the low frequency of occurrence of septic arthritis, persistent attention to the locomotor system in the transplant patient is warranted.

Abstract
The difficulty in diagnosis of tuberculosis in patients with chronic renal failure or on immunosuppressive therapy is discussed. Anti-tuberculous therapy was required in 19 out of 315 patients who received a renal transplant in the Urology Unit, Hammersmith Hospital, between February 1961 and December 1979. Twelve patients were from overseas. Their management and the effect of anti-tuberculous therapy on the immunosuppressed patient were also studied. The disease was treated successfully in 18 patients, even though there were problems with diagnosis. The patient who died had active tuberculosis on post-morten examination. Prophylaxis should be considered in patients who have had tuberculosis in the past and may have received inadequate treatment.

Abstract
Infections have produced most of the deaths in the Stanford cardiac transplant program. Of the first 182 transplant recipients, 27 developed nonviral intracranial infections: meningoencephalitis/abscess in 16 patients, meningitis in 9, and rhinocerebral phycomycoses in 2. The responsible organisms included aspergillus, toxoplasma, candida, klebsiella, cryptococcus, coccidioides, listeria, mucor, and rhizopus. Characteristically, the areas of meningoencephalitis and abscesses were multiple and deep seated. Intracranial infections were invariably associated with pulmonary or disseminated infection with same organism. Computed tomographic (CT) brain scans in patients with meningoencephalitis often showed minimal, nonspecific, low-density lesions which usually did not exhibit contrast enhancement. At surgery the lesions were found to differ from typical pyogenic abscesses in that capsules were not well developed, and the aspirate consisted of necrotic fragments of edematous white matter and inflammatory cells rather than liquefied pus. Aspergillus infections of the central nervous system usually developed within the first three months after transplantation. Cases of meningitis occurred at variable times after transplantation, but approximately half appeared within 30 days after immunosuppressive therapy for treatment of rejection was increased. The prognosis for brain abscess depended on the causative organism. All patients with aspergillus infection died despite treatment with amphotericin B. The toxoplasma abscess responded to a combination of sulfadiazine and pyrimethamine. Meningitis was successfully suppressed or cured with appropriate treatment except for 1 patient with disseminated cryptococcosis.

Abstract
Urinary tract infection is a frequent complication following renal transplantation and represents a potential focus for systemic infection in the immunosuppressed transplant recipient. The incidence, etiologic factors, temporal pattern, bacteriology, and prognostic significance of urinary tract infection were determined by analysis of 85 renal allografts in 69 patients. Significant bacteriuria occurred after 49 of 85 transplants (58 per cent). The incidence of infection was not related to success or source of the allograft, but was related to patient gender. Urinary tract infections developed in 68 per cent of females, while only 43 per cent of males became infected (p less than 0.05). Escherichia coli caused most first infections (30 per cent), while Pseudomonas aeruginosa and E. coli were equally responsible for recurrent infections (25 per cent each). Children with previous reconstructive urologic surgery had similar allograft success (63 per cent) and infection rates (53 per cent) as our other children (61 per cent and 58 per cent, respectively). No apparent correlation was noted between episodes of infection and graft rejection. Thorough preoperative assessment and preparation and prompt, specific treatment minimize the adverse influences of urinary tract infection.

Abstract
The case of a patient developing acute rejection crisis 8 months after transplantation in the prodromal stage of a herpes zoster infection is reported. The joint therapeutic measures resulted in suppression of rejection and control of the infection. Complications did not occur. The case suggests a definite association between the viral infection and acute homograft rejection. The case report is followed by a critical review of the pertinent literature.

Abstract
Five patients had opportunistic pulmonary infection caused by acid-fast bacilli, unusual clinical presentations and a unique pathological picture. Clinically, these cases mimicked septic pulmonary emboli or bacterial pneumonia. The infection was temporally related to high-dose corticosteroid therapy, given for renal-transplant rejection in four patients and for therapy of lymphocytic lymphoma in one. Histologic sections of lung-biopsy or autopsy material showed an acute suppurative pneumonia with dense alveolar infiltration by neutrophils, without granuloma formation or caseous necrosis. Predominantly intracellular acid-fast bacilli were present. The organism failed to grow in culture on routine bacterial, fungal and mycobacterial mediums. This unusual and possibly new acid-fast organism is a probable cause of suppurative pneumonia in impaired hosts receiving corticosteroid therapy.

Abstract
Renal allograft recipients were studied prospectively utilizing improved culture techniques to investigate anaerobic bacteriuria. The study population was compared with a population of patients with chronic renal insufficiency and end stage renal disease. The over-all incidence of anaerobic urinary tract infection was 7.5 per cent while the over-all incidence of aerobic urinary tract infection was 23.5 per cent. Patients with cadaver renal transplants during the early postoperative period had the highest incidnece of both anaerobic (42.9 per cent) and aerobic (71.4 per cent) urinary tract infection of all groups. The potential association between significant anaerobic bacteriuria during the first postoperative month and poor prognosis for cadaver renal allografts merits further investigation.

Abstract
Three patients with tuberculosis, all manifesting monarticular joint involvement, among 845 renal allograft recipients at the University of Minnesota are reported on. Clinical symptoms, methods of diagnosis, and optimal antibiotic regimes are discussed. The physician must suspect tuberculous joint disease when confronted with monarticular swelling and pain in the transplant recipient.

Abstract
Forty-six episodes of pulmonary infection occurred in 41 patients during a seven year period in which 187 renal transplants were performed in 168 patients. Thirty-seven episodes followed 152 cadaveric transplants (24.39%), and four episodes followed 35 living related donor transplants (11.4%). Five patients had two episodes of pulmonary infection. Twenty-four patients recovered, and 17 died (41.5%). Pulmonary infections appeared from two days to three years after transplantation, but predominated in the first four months (32/46). They were caused primarily by bacterial agents (74%) with protozoa, fungi, and viruses appearing less frequently. In 35 episodes, a single etiologic agent was found, but 11 were caused by two or more agents. When compared with noninfected recipients, there was no significant difference with regard to number of rejection crises, maintenance prednisone dosage, or blood glucose. However, subnormal renal function was significantly associated with the development of infection. Azathioprine dosages were actually higher for the noninfected patients, reflecting a tendency to lower the dose of azathioprine in the presence of decreased renal function. Fever was the most common presenting symptom. Transtracheal aspiration with Gram stain and direct sensitivity plating routinely provided early and accurate identification of the organism and a guide for therapy in bacterial infections. Pulmonary infection in renal transplant recipients is associated with a high mortality rate. Early diagnosis and specific treatment are essential to successful management.

Abstract
To assess the multiple risk factors reported to be associated with onset of serious bacterial, fungal, viral, and protozoal infections in renal allograft recipients, a retrospective study of all renal transplantations performed at Yale-New Haven Medical Center from the inception of the transplantation program in December, 1967, to December, 1975, was undertaken. Ninety-six renal allograft transplants in 85 patients were available for evaluation during this study period. Renal allograft recipients were evaluated for incidence of infection from time of transplantation until transplant nephrectomy, death, or January 1, 1976. All infections were characterized by type of infection, organism, site, and time of onset post-transplantation. Recipients with infections were also evaluated for their donor type, living-related or cadaveric, age at time of transplantation, granulocytopenia, corticosteroid therapy, and rejection episodes. There were 215 infections, 92 of which were defined as serious, in 78 of the 96 renal allograft recipients. Eighteen renal allograft recipients had no infections. Granulocytopenia, but not rejection, correlated with serious infections at some time in the patient's course. However, no significant temporal relationship between serious infections and episodes of granulocytopenia or rejection could be established. Mortality rate and incidence of serious infection was higher in the group receiving high dose corticosteroid therapy compared with the group receiving lower doses of corticosteroids. The mortality rate in these 85 transplant recipients was 33%. Seventy-four percent of these deaths were directly related to infection (24% of 85 patients).

Abstract
In 64 patients who had undergone renal transplantation, later on followed by bilateral nephrectomy, bacterial growth culture was performed from the original kidneys. The presence of bacteria in the nephrectomy specimens was compared with the occurrence of significant bacteriuria before transplantation and in the period between transplantation and nephrectomy. Bacteria could be cultured from the nephrectomy specimens of 18 (28.1 per cent) of the patients, almost exclusively confined to cases of obstructive chronic pyelonephritis, analgesic nephropathy and congenital renal disease. Before transplantation, bacteriuria had been recorded in 34.4 per cent of the patients, most frequently in the three groups of diseases just mentioned. Between the transplantation and nephrectomy, bacteriuria occurred in 75.0 per cent of the patients. Patients with E. coliuria before transplantation were particularly liable to have E. coliuria also after the transplantation and to E. coli in the nephrectomy specimens, whereas patients in whon E. coliuria did not occur until in the post-transplantation period were less susceptible to E. coli infection involving the kidneys. Probably the presence of bacteria in the nephrectomy specimens is related to the primary disease rather than to immunosuppressive and antiobiotic agents administered in the post-transplantation period.

Abstract
Urinary tract infection is the most frequent complication following renal transplantation and is important in the etiology of post-transplantation sepsis. The 87 renal homografts done in 1974 at The New York Hospital-Cornell Medical Center were reviewed retrospectively, with at least one year follow-up, in all cases, with particular attention to factors relating urinary tract infection to ultimate success or failure of the renal graft. The over-all incidence of urinary tract infection was 61%. Early infection was associated with a particularly poor prognosis for graft survival. Most patients with urinary infections after successful transplantation experience a combination of both early and late infections. Anatomic factors constitute a remediable cause of urinary infections after transplantation and should be searched for in cases of multiple, recurrent infections, de novo hypertension, or deterioration of previously stable graft function. There were significant differences in the bacteriologic spectrum of urinary tract infections associated with successful transplants as opposed to unsuccessful transplants.

Abstract
In 93 recipients of 102 orthotopic liver homografts, the incidence of bacteremia or fungemia exceeded 70%. The graft itself was usually an entry site for systemic infection after both immunologic and nonimmunologic parenchymal injury, especially if there was defective biliary drainage. The role of the homograft itself as the special infectious risk factor has prompted increased use of defunctionalized jejunal Roux limbs to reduce graft contamination. It has also stimulated very aggressive postoperative diagnostic efforts to rule out remedial mechanical complications of the transplant.

Abstract
Infection is an important cause of death in patients receiving cytostatic drugs or with any other impairment of host resistance. Such infections are frequently due to opportunist micro-organisms usually belonging to the endogenous flora of the patient. It is often difficult to obtain an exact diagnosis of the cause and localization of the infection. The problems associated with the prevention of infection are manifold. Exogenous infections can be prevented by proper isolation and a sterile diet. Endogenous infections can only be prevented by eradication of the patient's endogeous flora, so-called decontamination. Special attention should be given to treatment of foci of chronic infection and of the carrier state of certain microorganisms. However, the prophylactic use of antibiotics should be avoided. The curative use of antibiotics should be based on the most probable micro-organism. We consider the inventory of the patient's microflora, repeated weekly, of great help in the choice of antibiotics in cases of septicaemia of unknown aetiology. The initial therapy usually consists of a broad-spectrum combination of antibiotics, which should be bactericidal. When the causative bacteria have been isolated and the sensitivity is known, antibiotic therapy should be adjusted to the narrowest spectrum possible.

Abstract
A retrospective analysis of 193 renal transplant recipients yielded 15 patients who developed pulmonary mycosis posttransplantation and one case in which mycotic lung infection existed at the time of transplant surgery. Agent responsible for infection included Nocardia asteroides in 8 cases, Asperigillus flavus in 5 cases, Cryptococcus neoformans in 4 patients and Candida albicans in 2 cases. Two cases had mixed mycotic infections. Ten patients died, of which 7 had diagnosis established antemortem. Two cases had diagnosis established by thoracotomy and 1 case by transtracheal aspiration. Problems in establishing accurate diagnosis are discussed with emphasis placed on the need for more frequent use of transtracheal aspiration and thoracotomy for precise diagnosis.

Abstract
Miliary tuberculosis is the most lethal form of tubercular disease. If dissemination of tubercle bacilli occurs without therapy, death is almost certain. The importance of establishing an etiologic diagnosis as promptly as possible in patients receiving immunosuppressive therapy is self-explanatory. The presence of a life-threatening infection in these patients requires aggressive antimicrobial therapy and discontinuation of the immunosuppressive drugs until the infectious process is under control; the presence of an impaired immunologic response is responsible for the life-threatening infection and the lack of an acute rejection reaction.

Abstract
The effect of oral administration of neomycin cephalothin or kanamycin cephalothin on the aerobic intestinal bacterial flora, was studied in dogs maintained under isolation conditions in a conventional animal room. The dogs were successfully freed of aerobic bacteria with both combinations within two to seven days after the start of antibiotic treatment, and were maintained bacteria free for up to 21 days. Decontamination was attained more rapidly in dogs that were bathed in hexachlorophene surgical soap before and during the first and third days of antibiotic treatment. There was no evidence of toxicity from either of the antibiotic combinations. These results indicate that, as with mice and monkeys, decontamination of dogs with oral antibiotics is feasible. The technique is of potential value in preventing endogenous bacterial infections in canine experimental studies involving use of immunosuppressive agents.

Abstract
Tobramycin (factor 6 of the nebramycin complex) is a new aminoglycoside antibiotic isolated from Streptomyces tenebrarius which is active against S. aureus, Enterobacteriaceae, and Pseudomonas aeruginosa. Susceptibility to tobramycin of 96 strains of P. aeruginosa, including 45 recent isolates from blood, was studied by using agar and broth dilution methods. The minimum inhibitory concentration (MIC) for 83 of 96 strains was 3.12 mug/ml or lower in Mueller Hinton agar; MIC values were two to eight times lower in Mueller Hinton broth tests. Agar dilution MIC values were generally lower than those obtained in parallel tests with gentamicin. Killing curves obtained from serial sampling of broth cultures showed a 100- to 10,000-fold decline in viability of log-phase organisms within 30 min of exposure to the drug. Two-dimensional agar dilution tests with carbenicillin and tobramycin with 79 strains showed additive or synergistic effects; no antagonism was documented. Seventy-eight of 79 strains were inhibited by a combination of 50 mug of carbenicillin per ml and 1.56 mug of tobramycin per ml, blood levels which seem attainable in man. Tobramycin appears to be a potent, rapidly bactericidal antibiotic against P. aeruginosa and merits clinical evaluation.

Abstract
In 11 patients receiving transplants of allogeneic bone marrow, the graft was successful in six. Nine patients developed infections, and six died-five of septicaemia and one of Pneumocystis carinii pneumonia. Fifty individual infections occurred. Predisposing factors included severe underlying diseases, long-term exposure to resistant hospital organisms, heavy immunosuppressive therapy, and graft-versus-host disease. Gram-negative bacilli and Candida albicans were the most common causative organisms. In every instance of septicaemia identical organisms were isolated from blood cultures and simultaneously obtained stool cultures. Infection with exogenous organisms often occurred in patients occupying conventional isolation rooms. Isolation of one patient for 45 days in a laminar air flow room prevented infection with exogenous organisms.
