CMV presenting as a skin growth in renal transplant patient

CMV infection is one of the most common opportunistic infection in kidney transplant patients. If not treated, it is associated with increased mortality and graft loss. It can present as viremia or CMV disease in the form of CMV syndrome or tissue invasive CMV disease. The cutaneous presentation of CMV disease is a rare finding. Its identification is vital as cutaneous CMV infection can signal systemic infection and poor prognosis. In our case, 46-year-old male who was a post renal allograft recipient (RAR) presented as a protuberant growth over the medial side of the left ankle. On skin biopsy, nucleomegaly and inclusion bodies were seen in the epithelial cells. Immunohistochemistry was positive for CMV infection. Patient was treated with Ganciclovir, however, he succumbed to death because of severe sepsis due to secondary bacterial infection. Thus, CMV disease should always be kept in mind in immunocompromised patients like post RAR patients who present with cutaneous features like ulcerative lesions or fungating growth.

Etiological Spectrum of Infective Diarrhea in Renal Transplant Patient by Stool PCR: An Indian Perspective

Introduction:

Diarrhea is a common cause of morbidity and mortality among renal transplant patients. The etiological spectrum of pathogens varies with regional diversity, socioeconomic conditions, sanitation, and eating habits. We aimed to delineate the etiological profile of gastrointestinal pathogens in renal transplant patients using the stool Polymerase chain reaction.

Methods:

In this single-center, retrospective analysis of patients from January 2016 to January 2018, all renal transplant patients who were admitted with severe diarrhea and underwent the stool Polymerase chain reaction (PCR) were included. In the control group, we included patients from the general population who were admitted with similar complaints in the general medicine ward and underwent stool PCR over the same duration.

Results:

One hundred ten admissions occurred over 2 years in the transplant group. 86% of samples were positive for infection. More than one organism was seen in 68% of the patient. Norovirus was the most common organism isolated. Giardia lamblia with Norovirus was the most common coinfection among the transplant population. In the control group, 87% of samples tested positive, with 53% of patients having more than one organism. Enteroaggregative E. coli was the common organism, Enteroaggregative E. coli with Enteropathogenic E. coli and Enterotoxigenic E. coli were the most common organism in combination. Both the groups had similar incidence of infection with multiple organisms.

Conclusion:

The etiological profile of gastrointestinal pathogens differs significantly between the transplant and general population. Coinfections are common in both populations. Norovirus is the most common pathogen in the transplant population, presenting as isolated as well as in coinfections.

Quantitative analysis of myocardial metabolic heterogeneity is superior to visual assessment for the detection of active cardiac sarcoidosis by F-18 FDG PET-CT imaging

Funding Acknowledgements

Type of funding sources: None.

Background

Myocardial inflammation may occur in the context of a multisystem disease such as sarcoidosis, adversely affecting prognosis. A definitive diagnosis of cardiac sarcoidosis (CS) is essential to implementing life-saving treatment but this is complicated by the invasive nature of endomyocardial biopsy (EMB) and its low accuracy. Positron emission tomography (PET) assists in diagnosis, which relies on visual interpretation of myocardial F-18 FDG uptake. The value of quantitative analysis and its application to clinical practice remain uncertain.

Purpose

To investigate the power of quantitative F-18 FDG PET-CT imaging analysis for detecting CS in patients with suspected disease.

Methods

All patients underwent F-18 FDG PET-CT after a 24-hour low-carbohydrate diet and 15-hour fasting as part of their diagnostic work-up for suspected cardiac inflammation. Cardiovascular magnetic resonance acted as gatekeeper to PET-CT in 8 of every 10 scans. Myocardial F-18 FDG uptake was assessed qualitatively and quantitatively using both manually drawn regions of interest and automatic polar maps to measure global and segmental standardised F-18 FDG uptake values (SUV).  The coefficient of variation (CoV) was calculated to determine uptake heterogeneity. To confirm diagnosis, follow-up data regarding disease progression, further testing and treatment were collected. To allow for sufficient follow-up time, the first 40 consecutive patients from a prospective registry (n= 214; Sep 2017-Jun 2020) were included.

Results

A comprehensive clinical picture was obtained successfully in 37 patients (median [IQR], 17 [13.5] months) and a final diagnosis of CS reached in 7 (disease prevalence, 19%). EMB was performed in 2 patients only while 3 underwent PPM/ICD implantation. Significant predictors of CS were fulfilment of Japanese Ministry of Health and Welfare criteria (Wald, 6.44; p = 0.01) and left ventricular dysfunction (Wald 6.72; p = 0.01). Qualitative F-18 FDG PET-CT had a high negative (95%) but low positive (45%) predictive value for CS (sensitivity, 83%; specificity, 77%). F-18 FDG SUV CoV was the strongest imaging predictor (Wald, 6.77; p = 0.009) and was significantly higher in CS than non-CS (CoV median [quartiles], 0.26 [0.21, 0.36] and 0.12 [0.11, 0.14] respectively; p = 0.004). As per ROC curve analysis (AUC, 0.84), a CoV threshold of 0.20 was highly specific (93%) and sensitive (86%) for CS.

Conclusion

In a referring population with a low prevalence of cardiac sarcoidosis, F-18 FDG PET-CT imaging is sensitive for the detection of myocardial inflammation with active disease unlikely in patients with a negative scan. Quantitative evaluation of metabolic heterogeneity within the myocardium provides a strong, independent marker of active disease and should be considered alongside visual assessment.

Tacrolimus-induced epidermoid cysts in the renal transplant patient

Epidermal cysts are common benign cystic lesions that occur mostly sporadically. Common sites involved are arms, face, and trunk. The cyst may progress slowly and remain for years. These cysts arise as a result of the plugging of the follicular orifice. Etiology has largely remained unknown although local trauma, ultraviolet rays, and human papilloma virus (HPV) have been implicated in a few cases. Calcineurin inhibitors (CNIs) especially cyclosporine has been discredited for cutaneous side effects such as hirsutism and gingival hyperplasia. Epidermoid cysts have been also associated with patients with solid organ transplant recipients on cyclosporine. Tacrolimus is considered to be free of dermatological side effects. Herein, we report a case of 56-year-old renal allograft recipient on tacrolimus, who develop more than >100 epidermoid cysts over the face, trunk, back, and extremities. The lesions ceased to progress once the tacrolimus was stopped.

Hypervitaminosis D and acute interstitial nephritis: Tale of injections

A 33-year-old man came with nausea, vomiting and abdominal pain due to hypercalcaemia and renal dysfunction following two doses of intramuscular vitamin D injections. Levels of vitamin D were repeatedly above 300 ng/ml over a period of 10 months. Whole-body PET CT scan revealed a thin-walled collection in the right gluteal region. The patient refused a surgical intervention for the same. After 7 months of follow-up, the abscess ruptured spontaneously and was then surgically debrided. At this point, a history of pentazocine addiction was uncovered. One month later, vitamin D levels began to fall along with improvement in serum calcium and creatinine. This case unravels a diagnostic odyssey which ended with a simple surgical debridement. We aim to highlight that vitamin D supplementation in ‘megadoses’ in the presence of active infection can have an exaggerated response and may take months to resolve.

Predictors of Mortality after Surgery for Empyema Thoracis in Chronic Kidney Disease Patients

Background

Surgical treatment of empyema thoracis in patients with chronic kidney disease is challenging, and few studies in the literature have evaluated this issue. In this study, we aim to report the surgical outcomes of empyema and to analyze factors predicting perioperative mortality in patients with chronic kidney disease.

Methods

This retrospective study included data from 34 patients with chronic kidney disease (estimated glomerular filtration rate <60 mL/min/1.73 m2 for 3 or more months) who underwent surgery for empyema between 2012 and 2020. An analysis of demographic characteristics and perioperative variables, including complications, was carried out. Postoperative mortality was the primary outcome measure.

Results

Patients' age ranged from 20 to 74 years with a 29-to-5 male-female ratio. The majority (n=19, 55.9%) of patients were in end-stage renal disease (ESRD) requiring maintenance hemodialysis. The mean operative time was 304 minutes and the mean intraoperative blood loss was 562 mL. Postoperative morbidity was observed in 70.5% of patients (n=24). In the subgroup analysis, higher values for operative time, blood loss, intensive care unit stay, and complications were found in ESRD patients. The mortality rate was 38.2% (n=13). In the univariate and multivariate analyses, poor performance status (Eastern Cooperative Oncology Group >2) (p=0.03), ESRD (p=0.02), and late referral (>8 weeks) (p<0.001) significantly affected mortality.

Conclusion

ESRD, late referral, and poor functional status were poor prognostic factors predicting postoperative mortality. The decision of surgery should be cautiously assessed given the very high risk of perioperative morbidity and mortality in these patients.

The Haleem-Botchu classification: a novel CT-based classification for lumbar foraminal stenosis

PURPOSE

No clinical CT-based classification system is currently in use for lumbar foraminal stenosis. MRI scanners are not easily available, are expensive and may be contraindicated in an increasing number of patients. This study aimed to propose and evaluate the reproducibility of a novel CT-based classification for lumbar foraminal stenosis.

MATERIALS AND METHODS

The grading was developed as four grades: normal foramen-Grade 0, anteroposterior (AP)/superoinferior (SI) (single plane) fat compression-Grade 1, both AP/SI compression (two planes) without distortion of nerve root-Grade 2 and Grade 2 with distortion of nerve root-Grade 3. A total of 800 lumbar foramen of a cohort of 100 random patients over the age of 60 who had undergone both CT and MRI scans were reviewed by two radiologists independently to assess agreement of the novel CT classification against the MRI-based grading system of Lee et al. Interobserver(n = 400) and intraobserver agreement(n = 160) was also evaluated. Agreement analysis was performed using the weighted kappa statistic.

RESULTS

A total of 100 patients (M:F = 45:55) with a mean age of 68.5 years (range 60-83 years were included in the study. The duration between CT and MRI scans was 98 days (range 0-540, SD-108). There was good correlation between CT and MRI with kappa scores (k = 0.81) and intraobserver kappa of 0.89 and 0.98 for the two readers.

CONCLUSION

The novel CT-based classification correlates well with the MRI grading system and can safely and accurately replace it where required.

Immunoadsorption Column Reuse

Introduction:

Selective immunoadsorption (IA) is a technique to remove preformed Anti-ABO antibodies in ABO-incompatible renal transplants (ABOiRT). Since the cost of a single IA column is high and single use rarely achieves the target anti-ABO titers, its use is not widely spread. We studied the safety and efficacy of the reuse of IA columns in ABOiRT.

Methods:

Single-center, retrospective analysis of all patients who underwent ABOiRT with IA column reuse from January 2016 to July 2018. The column was reused after sterilization with ethylene oxide and flushed with normal saline before use. Target titers (IgG) were 1:4 preoperatively. Baseline IgG titers, plasma volume processed in each session, postoperative titer rebound were recorded. The primary outcome was IgG titer reduction after each use and adverse reaction during the IA column reuse. Patients were followed up until 1 year.

Results:

16 patients underwent ABOiRT using IA columns. Baseline IgG titer ranged from 1:32 to 1:512. Reuse of IA column was done 23 times and underwent 2^nd reuse for 9 times. The average plasma volume treated was 22 L. Efficacy of the IA column in log titer reduction of anti-ABO titer was 4 logs after the first use, 3 logs after 1^st reuse, and 1.5 logs after 2^nd reuse. 12 (75%) patients successfully reached the target IgG titer of ≤1:4 solely with column reuse. One patient received a single session of plasma exchange before transplantation. Postoperatively, one patient received one session of plasma exchange due to a rebound in anti-ABO antibodies. No serious side effects were noted during the reuse.

Conclusion:

IA column reuse up to two times showed efficacy in the successful reduction of antibody titers. Column reuse was not associated with any significant side effects.

Orbital exenteration and reconstruction in a tertiary UK institution: a 5-year experience

PURPOSE

Orbital exenteration is a radical oncological surgery that is usually indicated for advanced primary orbital tumors or invasion from local malignancy. We report a 5-year series from a tertiary head and neck center with particular focus on our ablative and reconstructive approach.

METHODS

We performed a clinicopathological review of patients referred to Guy's and St Thomas' NHS Foundation Trust Head and Neck multidisciplinary team for management input of an orbital malignancy during the period of 2013 to 2018. Cases involving local invasion from sinonasal malignancy were excluded. The reconstructive approach, perioperative complications, disease-free and overall survival were analyzed.

RESULTS

27 patients were identified and of those treated surgically, a radical extended orbital exenteration was required in almost half (44.4%), with squamous cell carcinoma being the most common pathology (55.6%). A concurrent neck dissection and parotidectomy were commonly performed with confirmed or suspected regional disease, or in the presence of high-risk pathological features. This approach resulted in favourable 2-year overall survival in these advanced stage cases of 84.6% and disease-free survival of 73.2%, with 92% achieving a negative surgical margin. The majority of treated patients required a free flap reconstruction, especially when an extended exenteration defect or adjuvant treatment was anticipated. The anterolateral thigh flap was the most commonly used donor site, and we present our algorithm for reconstruction of these defects.

CONCLUSIONS

A multidisciplinary approach to advanced orbital malignancy with a comprehensive approach to surgical resection and reconstruction results in favorable oncological outcomes and addresses functional and cosmetic patient rehabilitation.

P1339ARTERIOVENOUS FISTULA AND BASILIC VEIN TRANSPOSITION IN ELDERLY PATIENTS ON HEMODIALYSIS: AN OBSERVATIONAL STUDY

Background and Aims

With the increase in the line expectancy of chronic kidney disease in the older population (&gt;60 years), the numbers requiring haemodialysis is progressively rising. The elderly population may be different from the younger in terms of non-suitable vessels for access creation, non-maturation, and vascular calcifications, and this may alter the outcomes of use of arteriovenous fistula (AVF). This study was conducted to analyse the outcomes of AVF in elderly patients (&gt;60 years).

Method

Retrospective study was conducted in the Department of Nephrology at Sir Ganga Ram Hospital, New Delhi. Patients of more than 60 years of age in whom AVF was created from 1st January 2012 to 31st December 2016 were included in the study. Follow-up data of 3.5 years was analysed. The primary endpoint was to assess primary and secondary patency rates.

Results

A total of 300 patients were included in the study. The mean age was 63.8 years. Radiocephalic AVF (RCAVF) was the most common site of [69.8% (n = 210)], followed by brachiocephalic (BCAVF) in 25.2% (n = 75) and basilic vein transposition (BVT) in 5% (n = 15). At 12 months, overall survival of the AVF was 66.8%. At 42 months, the primary patency rate of RCAVF, BCAVF, and BVT was 50.6%, 52.6%, and 50.4% respectively. The commonest cause of access failure was thrombosis (20.4%) followed by non-maturation (9%). Vascular access abandonment was found least in BCAVF.

Conclusion

AVF remains the preferred vascular access for haemodialysis in the elderly population. Brachiocephalic AVF has higher primary and secondary patency rates. Thrombosis and failure of maturation are major concerns in the elderly AVF.

P1737MICROBIOLOGICAL DIAGNOSIS OF DIARRHEA IN RENAL TRANSPLANT PATIENT BY MULTIPLEX PCR

Background and Aims

Acute gastroenteritis is an unwelcome and harmful yet unavoidable complication in the renal transplant patient. Infections, especially atypical organisms like Norovirus, Cryptosporidium, along with typical microorganisms like E. coli and Giardia, form the significant players in the pathogenesis of diarrhea. Standard methods of staining and culture have reduced sensitivity as well as require considerable time for the reports. Stool Polymerase Chain Reaction (PCR)is a quick, sensitive, and hassle-free method that diagnoses more than 20 organisms within 1 hour. This study aims to determine the infective etiology of acute gastroenteritis in the transplant population as well to compare the yield of stool PCR with conservative methods.

Method

We retrospectively analyzed all renal transplant patients admitted between 2015 to 2018 with complaints of diarrhea (&gt;3 stools/day with loose consistency). The sample was tested for conventional microbiological methods, including a stool routine for microscopy and culture. A stool sample was also sent for Multiplex PCR, which was analyzed by Bio Fire FilmArray GI Panel, which identifies 22 enteropathogens. Endoscopic procedures were also undertaken in suspected cases for CMV colitis and pseudomembranous colitis.

Results

110 diarrheal events (admission for diarrhea) were recorded in 82 patients, with 181 organisms isolated in all samples. 16 events did not reveal any organisms in stool PCR. 85% sample yielded a positive result. The conventional method yielded a positive result in only 32.3% as compared to stool PCR. Co-infections were common, as 71.2% of events were associated with 2 or more organisms. Conventional methods failed to diagnose any co-infections. Norovirus G1/G2(20%) was the most common organism isolated from the stool, followed by Giardia (17%) and Enteropathogenic E. coli (16%). Giardia Lamblia with Norovirus G1/G2 was the most common co-infection in 19% of patients.

Conclusion

Stool PCR significantly improves the diagnostic yield in diagnosing enteric pathogens. Stool PCR is especially sensitive in detecting multiple organisms where conventional microbiological methods were completely unsuccessful. Norovirus is the most common enteropathogen, which is not picked by the conventional method. Giardia with Norovirus was the most common co-infection among post-transplant patients.

P1778PROFILE OF NON-BACTERIAL INFECTIONS SPECIFIC TO RENAL TRANSPLANT RECIPIENTS

Background and Aims

Infections in renal transplant recipients are a major cause of morbidity and mortality. It is the one of the major cause of patient death with functioning graft. Hence this project was done to study the profile of non-bacterial infections specific to renal transplant recipients and to determine the risk factors associated with such infections.

Method

Renal-transplant recipients admitted to the department of nephrology with suspected infection were included in the study.

Results

: A total of 342 patients were included in the study. The mean age of the patients was 45.2 ± 13.3 years. 17.5% had ABO incompatible renal transplant. 91% (87% received leukocyte depleting and 4% received non-leukocyte depleting agents) had received induction as majority had three or more HLA mismatch (70%) and the most common donor was wife. 12.8% had history of graft rejection. A total of 147 infectious episodes were encountered in 121 patients. The incidence of non-bacterial infections was 35% (121/342). Viral infections (68/147 = 46%) and invasive fungal infections (44/147 = 30%) were the most common. Cytomegalovirus infection was the most common 35%. Other viral infections encountered were BK virus associated nephropathy (2.3%) and reactivation of Hepatitis B or C virus (2.6%). The most common site of invasive fungal infection were lower respiratory tract, urinary tract, CNS cryptococcosis, soft tissue infection or cellulitis and oesophageal candidiasis in 41%, 32%, 9%, 9% and 9% respectively. Aspergillus (61%) and Rhizopus (33%) was the most common organism causing fungal pneumonia. Four patients were diagnosed with Pneumocystis jirovecii pneumonia. Majority (60%) of the infections were detected after one year post-transplant. Risk factors found to have statistically significance were ABO incompatibility, diabetes mellitus (pre or post-transplant) and history of graft rejection. Nine patients (7%) died of non-bacterial infections specific to renal transplant recipients.

Conclusion

Non-bacterial infections are not uncommon in Indian scenario and the timeline of such infections has changed.

P1267EFFECT OF SODIUM AND ULTRAFILTRATION MODELING VERSUS LOW TEMPERATURE DIALYSATE IN PREVENTION OF INTRADIALYSIS HYPOTENSION: A SINGLE CENTRE STUDY FROM INDIA

Background and Aims

Symptomatic intradialytic hypotension is the most frequent complication in patients receiving hemodialysis. It complicates 5 to 30 percent of all dialysis treatments. In our study, we aimed to compare the effect of sodium and ultrafiltration modeling versus low-temperature dialysate on the occurrence of intradialytic hypotensive episodes.

Method

Single center, prospective, randomized trial. Patients with chronic kidney disease (CKD) stage V on maintenance hemodialysis (HD) for at least twice weekly for a minimum of 3 months were observed for the occurrence of ≥1 intradialytic hypotensive episode per month. After full filling the inclusion and exclusion criteria, patients were randomized 1:1 ratio into two groups based on computer-generated randomization numbers allotted to them by the dialysis coordinator.

Group 1: Underwent dialysis with sodium and Ultrafiltration modeling (Linearly decreasing dialysate sodium from 141 mmol/L to 128 mmol/L and linearly decreasing ultrafiltration rate).

Group 2: Underwent dialysis with low-temperature dialysate (36 degrees Celsius).

Primary outcome was number of hypotensive episodes per month. Secondary outcomes were interdialytic weight gain and ultrafiltration volume per session.

Results

A total of 320 patients were observed for 3 months in our centre. Intradialytic hypotension was found in 18.75 % of patients. Diabetic nephropathy (61.66%) was the leading cause of end-stage renal disease in these patients. There was no significant difference between the two groups in mean arterial blood pressure, hemoglobin, cardiac status, and serum albumin before dialysis. Both groups had a similar incidence of intradialytic hypotensive episodes (P &gt;0.05). Interdialytic weight gain and ultrafiltration volume removed per session were also similar in both groups.

Conclusion

Sodium and ultrafiltration modeling and low-temperature dialysate were both equally effective in the prevention of intradialytic hypotensive episodes.

P1181URGENT START OF PERITONEAL DIALYSIS: OUTCOMES AND EXPERIENCE FROM NORTHERN INDIA

Background and Aims

Peritoneal dialysis (PD) widely practiced as the first-line modality for renal replacement therapy in end-stage renal disease (ESRD) patients. Urgent-start PD (use of the PD catheter within 14 days of insertion) is an effective approach to prompt initiation of PD after catheter insertion. However, there is a paucity of data regarding complications of urgent-start PD. We investigated the outcomes of urgent-start PD in our subset (Indian population).

Method

All patients in whom PD was initiated between 01 January 2015 and 31 July 2019 (54 months) were included. Patients were grouped according to the initiation of PD (break-in period) as &lt;8 days (PD1), 8 to 14 days (PD2), and &gt;14 days (PD3).

Results

In 100 patients included in the study, 57.5% were males. Among them, 75%, 10%, and 15% patients were in the PD1, PD2, PD3 break-in groups respectively. The most common cause of ESRD was diabetes mellitus. Functional catheter malfunction was the most frequent complication in PD1. The incidence of mechanical complications during the first six months was similar in all three groups (p = 0.06). No significant differences with respect to the catheter dysfunction requiring surgical intervention (p &gt; 0.05) were observed. In PD1 group, catheter patency rate at the end of the 1-month and 1-year was 98.6% and 95.4% respectively. No significant differences were found in the rate of peritonitis among the three groups. Female sex, low haemoglobin, and low albumin levels were independent risk factors for peritonitis.

Conclusion

Early break-in period of less than seven days is a feasible option for patients requiring urgent dialysis with no increased risk of mechanical or infectious complications. It offers a safe and efficacious option for unplanned ESRD patients.

PRIMARY LARYNGEAL ASPERGILLOSIS IN AN IMMUNOCOMPETENT PATIENT

Background. Aspergillus is an inherently ubiquitous, weakly pathogenic fungus causing opportunistic infections. It is very rarely localized in the larynx, although laryngeal Aspergillosis may develop in the immunocompromised patients including those with leukaemia and severe aplastic anaemia. Objective. The aim of the research was to explore the primary laryngeal Aspergillosis in an immunocompetent patient thru a case report. Methods. A case report of primary laryngeal Aspergillosis in an immunocompetent patient is presented. Results. A male patient of 40 years old, presenting with chronic worsening hoarseness, was found to have a smooth, white spheroid submucosal growth on left vocal cord with preserved bilateral cord movements on videostroboscopy. Histopathological examination of vocal cord growth revealed squamous epithelium containing septate hyphae with acute angle dichotomous branching pattern consistent with Aspergillus. Voice improved after a four-week course of oral itraconazole 200 mg/day. Post therapy follow up of 24 months was unremarkable. Conclusions. Primary laryngeal Aspergillosis develops in the immunocompetent patients. Iatrogenic, vocal abuse, occupation and lifestyle factors may be contributory. Optimal diagnosis and management mandates a high index of suspicion.

Intraprocedural complications of uterine fibroid embolisation and their impact on long-term clinical outcome

OBJECTIVES

Authors evaluate the impact of intraprocedural complications on successful technical realisation and long-term clinical outcome of the uterine fibroid embolisation.

BACKGROUND

The uterine artery embolisation (UAE) has become an accepted treatment method for uterine fibroids. In general, the unilateral embolisation is considered to be insufficient due to poor clinical effect.

METHODS

Overall, 165 uterine artery embolisations were analysed (retrospectively-prospectively) in 163 female patients. Intraprocedural complications and their impact on the possibility to perform bilateral embolisationwere evaluated. In patients with unscheduled unilateral embolisation, short-term as well as long-term clinical effects were observed with mean follow-up period of 41 months.

RESULTS

The bilateral uterine artery embolisation was possible in 95.7 % (95 %, CI 91.3-99.4 %) procedures. The unilateral embolisation was reported in 7 procedures (4.3 %, CI 1.2-8.3 %) and reasons were following: resistant arterial spasm in 4 patients (2.5 %, CI 0.7 %-5.3 %) and impossible catheterisation due to unfavourable anatomic situation in 3 patients (1.8 %, CI 0.3-4.1 %). Other complications, such as dissection and perforation, did not affect the successful technical realisation. The long-term clinical effect of unscheduled unilateral embolisation was reported in 5 patients.

CONCLUSION

The results of our series of unscheduled unilateral uterine fibroid embolisation had high long-term clinical success rate. In way of unscheduled unilateral embolisation, we recommend MRI follow-up and reintervention only in way of persistence or recurrence of symptoms with concurrent MRI finding of residual fibroids(Tab. 5, Fig. 3, Ref. 12).

Delayed Presentation of Renal Arterio-Venous Fistula and Pseudoaneurysm in Native Left Kidney in Allograft Recipient: A Case Report

Iatrogenic complications due to renal biopsy majorly include formation of an arterio-venous fistula, pseudoaneurysm or arterio-ureteral fistula. These complications are observed within a span of few days post biopsy and are rare after few years. We reported a case of32-year-old renal allograft recipient male presenting 6 years post biopsy of the left kidney with left lumbar region pain who was eventually diagnosed with arterio-venous fistula and pseudoaneurysm involving inferior interlobular branch of left renal artery. Superselective embolization was achieved using coils and high concentration glue and transient placement of a venous occlusion balloon with complete technical and clinical success.

Abstract P5-07-05: Obesity, adipose inflammation, and race in patients with early stage breast cancer

Background: Elevated body mass index (BMI) is associated with increased risk of estrogen receptor-positive postmenopausal breast cancer. Mechanistically, most individuals with elevated BMI have breast white adipose tissue inflammation (WATi) which confers increased breast cancer risk, particularly in those with existing benign breast disease. Individuals with WATi have elevated in-breast expression of aromatase and several systemic changes that increase breast cancer risk, including hyperinsulinemia and higher levels of C-reactive protein. However, women with normal BMI but high levels of body fat are also likely to harbor WATi and are at increased risk of postmenopausal breast cancer. The accuracy of BMI for assessing adiposity and predicting obesity-related disorders, including cancer, varies across race and ethnicity. Whether the association between BMI and WATi varies by race is unknown. Here we aimed to characterize relationships among breast WATi and clinicopathologic features in a racially diverse cohort undergoing mastectomy for breast cancer treatment.

Methods: Non-tumorous breast tissue and fasting blood were collected from women undergoing mastectomy for breast cancer treatment or prevention at a single center serving a racially diverse patient population. Breast WATi was detected by the presence of crown-like structures in the breast (CLS-B), which are composed of a dead/dying adipocyte surrounded by CD68+ macrophages. Clinicopathologic data were abstracted from electronic medical records. Associations among categorical variables were examined using Fisher's exact test. Relationships between continuous variables were examined using the Spearman correlation.

Results: As of May 18, 2018 62 patients have been accrued; median age 55 (range 32 to 84). Self-reported race distribution was: 36 (58%) Asian, 5 African American (8%), 20 (32%) Caucasian, and 1 (2%) unknown. Breast tissue has been analyzed for WATi in 60 cases thus far. Clinicopathologic features stratified by the presence or absence of breast WATi are presented in. Breast WAT inflammation was associated with obesity (P=0.02) and a trend to association was observed with dyslipidemia (P&lt;0.09).

Conclusions: Breast adipose inflammation is associated with elevated BMI and possibly metabolic syndrome disorders in a racially diverse population. These findings are consistent with observations from predominantly Caucasian cohorts. Race-specific characteristics will also be examined. Study accrual is ongoing and updated results will be presented.

BK Virus nephropathy in living donor renal allograft recipients: An observational study from a large transplant center in India

BK virus is a polyoma virus which remains in latent phase in the urinary tract, particularly in the renal tubular epithelial cells. In immunosuppressed patients, it is activated and manifests as tubule-interstitial nephritis causing renal allograft dysfunction. A total of 402 patients who underwent renal allograft biopsy from 2013 to 2016 were included in this study; six patients were diagnosed to have BK virus nephropathy. Histopathology showed ground glass intra-nuclear inclusions accompanied by acute tubular injury, interstitial inflammation, and varying degree of interstitial fibrosis and tubular atrophy. Patients were managed with reduction in the overall immunosuppression. Only one patient progressed to graft failure on follow-up. The overall prevalence of polyoma virus at our center is 1.49%.

HEMOPHAGOCYTOSIS SECONDARY TO PHARYNGEAL ABSCESS IN AN IMMUNOCOMPETENT PATIENT (case report)

Background. Hemophagocytosis is a rare, potentially fatal disorder, comprising pancytopenia, liver dysfunction, hepatosplenomegaly, hypertriglyceridemia, and hyperferritinemia presenting as fever, lympha­denopathy and skin rashes. Objective. To attract the clinicians’ attention to a problem of hemophagocytosis in Critical Care management.Methods. Hemophagocytosis secondary to pharyngeal abscess in a 58 year old male is being reported.Results. A 58-year-old immunocompetent patient presenting with hemophagocytosis secondary to pharyngeal abscess, was managed on ventilator and inotropic support, when he developed heathcare-associated urinary tract infection by Escherichia coli and ventilator-associated pneumonia by Acinetobacter baumanii. He developed neutropenic septic shock and multi-organ dysfunction and went through a downhill course leading to demise.Conclusions. Hemophagocytosis remains a sinister entity in modern intensive care despite astute clinical management. Secondary superinfections with opportunistic multidrug resistant pathogens are difficult to treat. A high index of clinical suspicion, aggressive diagnosis and prompt treatment for hemophagocytosis and polymicrobial opportunistic superinfections with multidrug-resistant healthcare-associated pathogens needs to be addressed upfront.

The impact of geriatric focused nurse assessment and intervention in the emergency department: A systematic review

BACKGROUND

Nursing assessment of elderly patients is imperative in Emergency Departments (ED) while providing interventions that increase independence facilitating discharge to primary healthcare.

AIMS

To systematically review the impact of geriatric focused nurse assessment and intervention in the ED on hospital utilisation in terms of admission rate, ED revisits and length of hospital stay (LOHS).

METHODS

Search strategy used following databases; Cochrane, Medline, CINAHL, Embase, Scopus and Web of Knowledge; And terms; geriatric nurse assessment, nurse discharge planning, geriatric nurse specialist, nurse intervention, emergency department, accident and emergency, patient outcomes, discharge, admissions, readmissions, hospital utilization, hospitalization, length of stay/hospital stay.

RESULTS

Nine studies were included: seven RCTs and two prospective pre/post-intervention designed studies. Geriatric focused nursing assessment and interventions did not have a statistical impact on hospitalization, readmissions, LOHS and ED revisits. Risk screening and comprehensive geriatric assessment extending into primary care may reduce readmission rates but not affect hospitalization. An increase in ED visits in the intervention group at 30 days post-intervention was noted.

CONCLUSION

Inconsistencies in assessment and interventions for the older person in ED are apparent. Further research evaluating a standardised risk assessment tool and innovative interventions extending into primary healthcare is required.

Relationship between day 1 and day 2 Vancomycin area under the curve values and emergence of heterogeneous Vancomycin-intermediate Staphylococcus aureus (hVISA) by Etest® macromethod among patients with MRSA bloodstream infections: a pilot study

BACKGROUND

In vitro data suggests that suboptimal initial vancomycin exposure may select for heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) infections. However, no clinical studies have evaluated the relationship between initial vancomycin exposure and emergence of hVISA. This pilot study seeks to assess the relationship between day 1 and day 2 vancomycin area under the curve (AUC) and emergence of hVISA bloodstream infections (BSIs) by Etest® macromethod among patients with a non-hVISA BSI at baseline.

METHODS

This was a retrospective cohort study of patients with methicillin-resistant Staphylococcus aureus (MRSA) BSIs at Albany Medical Center Hospital (AMCH) between January 2005 and June 2009. The vancomycin AUC exposure variables on day 1 (AUC_0-24h) and day 2 (AUC_24-48h) were estimated using the maximal a posteriori probability (MAP) procedure in ADAPT 5.

RESULTS

There were 238 unique episodes of MRSA BSIs during the study period, 119 of which met inclusion criteria. Overall, hVISA emerged in 7/119 (5.9%) of patients. All 7 cases of hVISA involved patients who did not achieve area under the curve over broth microdilution minimum inhibitory concentration (AUC_0-24h/MIC_BMD) ratio of 521 or an AUC_24-48h/MIC_BMD ratio of 650. No associations between other day 1 and day 2 AUC variables and emergence of hVISA were noted.

CONCLUSIONS

Although more data are needed to draw definitive conclusions, these findings suggest that hVISA emergence among patients with non-hVISA MRSA BSIs at baseline may be partially explained by suboptimal exposure to vancomycin in the first 1 to 2 days of therapy. At a minimum, these findings support further study of the relationship between initial vancomycin exposure and hVISA emergence among patients with MRSA BSIs in a well-powered, multi-center, prospective trial.
