Effect of counseling model on diabetic women regarding sexual dysfunction: a quasi-experimental study.

BACKGROUND: Complications of diabetes in women have adverse effects on their self-image, quality of life, health, and other social relationships, thereby leading to sexual dysfunction. maternity nurse care can play a critical role in assessing the knowledge about needs for sexual health. AIM: The present study aims to evaluate the effect of the counseling model on female patients with diabetes regarding sexual dysfunction. METHOD: A quasi-experimental research design was used to conduct the study at the diabetic and obstetric outpatient clinic in 2 hospitals (Al Salam Port Said General Hospital, Elzohor General Hospital), and in five centers in Port Said City (El-Kuwait Center, Othman Ibnafan Center, El-arab 1 center, El-manakh center, El-arab2 center). A purposive sample of 178 female diabetic patients was included in the study. Two tools were used for collecting data consisted of; (1 interview questionnaire sheet) including personal characteristics, medical history, and present sexual problem of the studied female patients, (and 2 female sexual function index (FSFI). RESULTS: the current study revealed that there was a high statistical difference between female sexual function in post with mean ± SD (23.3 ± 4.1) compared to pre-educational intervention with mean ± SD (19.5 ± 3.7), while there was a high statistically significant difference among pre- & post-program application regarding female sexual function index (p > 0.001). CONCLUSION: the counseling model had a positive effect in improving the sexual function among female patients with diabetes. TRIAL REGISTRATION NUMBER (TRN): The study protocol was approved by the Research Ethics Committee of the Faculty of Nursing, Port Said University (code number: NUR 12/9/2021-6).

Protective effects of Urtica dioica on the cerebral cortex damage induced by Potassium bromate in adult male albino rats.

Potassium bromate is used in cheese production, beer making and is also used in pharmaceutical and cosmetic. It is a proven carcinogen as it is a strong oxidizing agent that generates free radicals during xenobiotic metabolism. Urtica dioica (Ud) (from the plants' family of Urticaceae) is a plant that has long been used as a medicinal plant in many parts of the world. It has been shown to have anti-inflammatory, antioxidant and immunosuppressive properties. So, this study aimed to clarify the effect of Potassium bromate on the histological structure of cerebral cortex of adult male albino rats, evaluate the possible protective role of Urtica dioica. Thirty adult healthy male albino rats were divided into three groups; group I (Control group), group II (KBrO3 treated group). Group III (KBrO3 and Urtica dioica treated group).At the end of the experiment, rats in all groups were anesthetized and specimens were processed for light and electron microscope. Morphometric and statistical analyses were also performed. Nerve cells of the treated group showed irregular contours, dark nuclei, irregular nuclear envelopes, dilated RER cisternae, and mitochondria with ruptured cristae. Vacuolated neuropil was also observed. Immunohistochemically, stained sections for GFAP showed strong positive reaction in the processes of astrocytes. Recovery group showed revealed nearly the same as the histological picture as the control group. In conclusion, potassium bromate induces degenerative effects on neurons of cerebral cortex and urtica dioica provide an important neuroprotective effects against these damaging impacts through their antioxidant properties.

Pre-transplant hypoalbuminemia is not associated with worse short-term outcomes among kidney transplant recipients.

INTRODUCTION: Serum albumin is an indicator of overall health status, but it remains unclear how pre-transplant hypoalbuminemia is associated with early post-transplant outcomes. METHODS: This study included all adult kidney transplant recipients (KTRs) at our center from 01/01/2001-12/31/2017 with serum albumin measured within 30 days before transplantation. KTRs were grouped based on pretransplant albumin level normal (≥4.0 g/dL), mild (≥3.5 - < 4.0g/dL), moderate (≥3.0 - < 3.5g/dL), or severe hypoalbuminemia (<3.0g/dL). Outcomes of interest included: length of hospital stay (LOS), readmission within 30 days, delayed graft function(DGF), and re-operation related to post-transplant surgical complications. We also analyzed rejection, graft failure, and death within 6 months post-transplant. RESULTS: A total of 2807 KTRs were included 43.6% had normal serum albumin, 35.3% mild, 16.6% moderate, and 4.5% severe hypoalbuminemia. Mild and moderate hypoalbuminemia were associated with a shorter LOS by 1.22 (p < 0.001) and 0.80 days (p = 0.01), respectively, compared to normal albumin. Moderate (HR: 0.58; 95% CI: 0.37-0.91; p = 0.02) and severe hypoalbuminemia (HR: 0.21; 95% CI: 0.07-0.68; p = 0.01) were associated with significantly lower rates of acute rejection within 6 months post-transplant. CONCLUSION: Patients with pre-transplant hypoalbuminemia have post-transplant outcomes similar to those with normal serum albumin, but with a lower risk of acute rejection based on the degree of hypoalbuminemia.

Discordance in cytomegalovirus viremia in kidney recipients from the same donor is associated with the worst outcomes.

BACKGROUND: Cytomegalovirus (CMV) is a common viral infection in kidney transplant recipients (KTR) that has been associated with negative outcomes. The effect on outcomes of concordance versus discordance in CMV between two different recipients of kidneys from the same donor is largely unknown. METHODS: We reviewed all adult deceased donor kidney transplant recipients (DDKTs) for which both kidneys were transplanted to two different recipients at our center between 2014 and 2019. Recipient pairs from each donor were divided into groups based on concordance or discordance for the development of CMV viremia between the pair; concordant no CMV (cc-no-CMV) if neither KTR developed CMV, concordant CMV (cc-CMV) if both KTRs developed CMV. The discordant group was then further divided based on the individual development of CMV (dc-CMV) or lack of development of CMV (dc-no-CMV). Patient mortality and death-censored graft failure (DCGF) were outcomes of interest. RESULTS: Of 578 KTRs, 67% were cc-no-CMV, 5% were cc-CMV, 14% were dc-no-CMV, and 14% dc-CMV. Some of the baseline characteristics differ among the groups including a higher prevalence of high-risk serostatus (D+/R-) in cc-CMV (32%) and dc-CMV (32%). In multivariate analysis, with reference to cc-no-CMV, dc-CMV was associated with increased risk for DCGF (HR 3.13, 95% CI 1.58-6.19), and so was delayed graft function. Factors associated with increased risk of mortality were advanced recipient age and DGF. cc-CMV was neither associated with mortality nor DCGF. CONCLUSIONS: These findings support that in certain contexts, CMV viremia has adverse allograft outcomes, and this is highlighted when illustrated via discordance in CMV between pair kidneys from the same deceased donor.

Hypoalbuminemia is a risk factor for invasive fungal infections and poor outcomes in infected kidney transplant recipients.

INTRODUCTION: Invasive fungal infections (IFI), are estimated to occur in 2%-14% of kidney transplant recipients (KTRs) in the current era of immune suppression and are associated with high mortality rates. We hypothesized that hypoalbuminemia in KTRs is a risk factor for IFI and would be associated with poor outcomes. METHODS: In this study, using data from a prospective cohort registry, we describe the frequency of IFI due to Blastomycosis, Coccidioidomycosis, Histoplasmosis, Aspergillosis, and Cryptococcus in KTRs with serum albumin levels measured 3-6 months before diagnosis. Controls were selected based on incidence density sampling. KTRs were divided into three groups based on the pre-IFI serum albumin level: normal (≥4 g/dL), mild (3-4 g/dL), or severe (<3 g/dL) hypoalbuminemia. Outcomes of interest were uncensored graft failure after IFI and overall mortality. RESULTS: A total of 113 KTRs with IFI were compared with 348 controls. The incidence rate of IFI among individuals with normal, mild, and severe hypoalbuminemia was 3.6, 8.7, and 29.3 per 100 person-years, respectively. After adjustment for multiple variables, the trend for risk of uncensored graft failure following IFI was greater in KTRS with mild (HR = 2.1; 95% CI, .75-6.1) and severe (HR = 4.47; 95% CI, 1.56-12.8) hypoalbuminemia (P-trend < .001) compared to those with normal serum albumin. Similarly, mortality was higher in severe hypoalbuminemia (HR = 1.9; 95% CI, .67-5.6) compared to normal serum albumin (P-trend < .001). CONCLUSION: Hypoalbuminemia precedes the diagnosis of IFI in KTRs, and is associated with poor outcomes following IFI. Hypoalbuminemia may be a useful predictor of IFI in KTRs and could be incorporated into screening algorithms.

Hordeum vulgare ethanolic extract mitigates high salt-induced cerebellum damage via attenuation of oxidative stress, neuroinflammation, and neurochemical alterations in hypertensive rats.

High salt intake increases inflammatory and oxidative stress responses and causes an imbalance of neurotransmitters involved in the pathogenesis of hypertension that is related to the onset of cerebral injury. Using natural compounds that target oxidative stress and neuroinflammation pathways remains a promising approach for treating neurological diseases. Barley (Hordeum vulgare L.) seeds are rich in protein, fiber, minerals, and phenolic compounds, that exhibit potent neuroprotective effects in various neurodegenerative diseases. Therefore, this work aimed to investigate the efficacy of barley ethanolic extract against a high salt diet (HSD)-induced cerebellum injury in hypertensive rats. Forty-eight Wistar rats were divided into six groups. Group (I) was the control. The second group, the HSD group, was fed a diet containing 8% NaCl. Groups II and III were fed an HSD and simultaneously treated with either amlodipine (1 mg /kg b.wt p.o) or barley extract (1000 mg /kg b.wt p.o) for five weeks. Groups IV and V were fed HSD for five weeks, then administered with either amlodipine or barley extract for another five weeks. The results revealed that barley treatment significantly reduced blood pressure and effectively reduced oxidative stress and inflammation in rat's cerebellum as indicated by higher GSH and nitric oxide levels and lower malondialdehyde, TNF-α, and IL-1ß levels. Additionally, barley restored the balance of neurotransmitters and improved cellular energy performance in the cerebellum of HSD-fed rats. These findings suggest that barley supplementation exerted protective effects against high salt-induced hypertension by an antioxidant, anti-inflammatory, and vasodilating effects and restoring neurochemical alterations.

Pseudodominant Alport syndrome caused by pathogenic homozygous and compound heterozygous COL4A3 splicing variants.

Alport syndrome is a genetic disorder affecting the basement membranes of the kidney, ear and eye, and represents a leading cause of monogenic kidney disease. Alport syndrome is genetically heterogeneous with three key genes involved (COL4A3-5) and several transmission patterns, including monogenic X-linked, autosomal recessive/dominant and digenic. We report a consanguineous family where 13 individuals presented variable features of Alport syndrome including kidney failure on two generations and male-to-male transmission, suggesting autosomal dominant inheritance. COL4A3-5 gene panel analysis surprisingly reveals two distinct, confirmed splice-altering variants in COL4A3 (NM_000091.4: c.1150+5G>A and c.4028-3C>T) present in homozygous or compound heterozygous state in individuals with kidney failure. This adds a further mode of transmission for Alport syndrome where, in a consanguineous family, the independent segregation of two variants at the same locus may create a pseudodominant transmission pattern. These findings highlight the importance of a molecular diagnosis in Alport syndrome for genetic risk counselling, given the variable modes of inheritance, but also the pitfalls of assuming identity by descent in consanguineous families.

Factors affecting sensitization following kidney allograft failure.

INTRODUCTION: Management of immunosuppression in a kidney transplant recipient with a failed allograft is complex; continuation carries infectious and metabolic risks, and discontinuation can lead to sensitization. METHODS: We evaluated risk factors for sensitization in 89 kidney or simultaneous kidney-pancreas recipients, whose kidney transplant failed after January, 2013 and who were subsequently re-evaluated for kidney transplantation. RESULTS: Among recipients with pre graft failure cPRA < 50%, calcineurin inhibitor (CNI) continuation (OR .11, P = .003) and steroid continuation (OR .17, P = .04) were associated with significantly lower odds of developing an absolute increase in cPRA of ≥50%. Each additional HLA mismatch was associated with OR of 2.16 (P = .02). CNI use was associated with OR of .09 (P = .001) for increase in cPRA to ≥80% if pre graft failure cPRA was <50%, and OR of .08 (P = .02) for increase in cPRA to ≥98% if pre graft cPRA was <80%. Anti-metabolites were continued more often among recipients who had a <50% increase (P = .006); however, the association was lost on multivariate analyses. Weaning off immunosuppression and higher number of HLA mismatches are associated with greater likelihood of sensitization. CONCLUSION: While both CNI and steroid continuation conferred some protection against increase in cPRA, CNI continuation was the only factor protecting against becoming highly sensitized.

Kidney transplant outcomes among recipients with post-transplant hip or knee joint replacement surgery.

INTRODUCTION: Patients with end-stage renal disease (ESRD) are at a higher risk of needing hip or knee replacement (joint replacement) surgery due to the high prevalence of degenerative joint disease and other conditions. However, there remains a large debate about the timing of joint replacement surgery and whether it should be pre- vs post-transplant. METHODS: We conducted a retrospective study analyzing all adult kidney transplant recipients (KTRs) at our university hospital who had undergone subsequent joint replacement between 2001 and 2017. Transplant-specific outcomes of acute rejection, death censored graft failure (DCGF), and patient death post-joint replacement surgery were outcomes of interest. Controls were selected at a 1:3 ratio based on the incidence density sampling of post-transplant interval. RESULTS: There were 101 KTRs in the joint replacement group and were compared with 281 controls. In the multivariate analysis, the need for joint replacement was not associated with acute rejection (HR: 1.59; 95% CI: 0.77-3.29; P = 0.21); DCGF (HR: 0.89; 95% CI: 0.49-1.60; P = 0.70) or patient death (HR: 0.84, 95% CI: 0.55-1.38, P = 0.42). CONCLUSION: In selected KTRs, joint replacement surgery was not associated with detrimental transplant-specific outcomes.

In kidney recipients from the same deceased donor, discordance in delayed graft function is associated with the worst outcomes.

INTRODUCTION: Delayed graft function (DGF) is a common complication among deceased donor kidney transplant recipients (DDKTs) and is associated with worse outcomes. The effect on outcomes of concordance versus discordance in DGF between two different recipients of kidneys from the same donor is largely unknown. METHODS: We reviewed all adult DDKTs for which both kidneys were transplanted to two different recipients at our center between 2014-2019. DDKTs were divided into four groups based on the DGF status: concordance no DGF (cc-no-DGF); discordance no DGF(dd-no-DGF); discordance DGF (dd-DGF) and concordance in DGF (cc-DGF). Acute rejection (AR) and death censored graft failure (DCGF) were outcomes of interest. RESULTS: A total of 578 DDKTs fulfilled our selection criteria, 280were in cc-no-DGF, 83 in dd-no-DGF, 83 in dd-DGF, and 132 in cc-DGF. Compared to cc-no-DGF, in univariate analysis, dd-DGF was associated with an increased risk of AR (HR: 1.60; 95% CI: 1.0-2.56) but cc-DGF was not (HR: 1.01; 95% CI: 0.63-1.62). dd-DGF was not associated with an increased risk of AR in multivariate analysis. In multivariate analysis, dd-DGF was associated with an increased risk of DCGF (HR: 2.70; 95% CI: 1.05-6.93) but cc-DGFwas not (HR: 2.36; 95% CI: 0.97-5.70). CONCLUSION: Discordance in DGF is associated with worse outcomes and may need closefollow-up and monitoring to improve the outcomes.

Bioimpedance spectroscopy: Is a picture worth a thousand words?

Volume status can be difficult to assess in dialysis patients. Peripheral edema, elevated venous pressure, lung crackles, and hypertension are taught as signs of fluid overload, but sensitivity and specificity are poor. Bioimpedance technology has evolved from early single frequency to multifrequency machines which apply spectroscopic analysis (BIS), modeling data to physics-based mixture theory. Bioimpedance plots can aid the evaluation of hydration status and body composition. The challenge remains how to use this information to manage dialysis populations, particularly as interventions to improve over hydration, sarcopenia, and adiposity are not without side effects. It is therefore of no surprise that validation studies for BIS use in peritoneal dialysis patients are limited, and results from clinical trials are inconsistent and conflicting. Despite these limitations, BIS has clinical utility with potential to accurately evaluate small changes in body tissue components. This article explains the information a BIS plot ("picture") can provide and how it can contribute to the overall clinical assessment of a patient. However, it remains the role of the clinician to integrate information and devise treatment strategies to optimize competing patient risks, fluid and nutrition status, effects of high glucose PD fluids on membrane function, and quality of life issues.

Risk factors and outcomes of BK viremia among deceased donor kidney transplant recipients based on donor characteristics.

INTRODUCTION: BK polyomavirus (BKV) is a common infection among kidney transplant recipients (KTR). Risk factors and outcomes based on donor characteristics remain largely unknown. METHODS: In this study, we aimed to analyze the impact of donor factors through a paired kidney analysis. We included 289 pairs of adult deceased donor transplants (578 KTRs total); each pair had received kidneys from the same donor. Recipient pairs were divided into three groups: "no BK group" if neither KTR developed BK viremia (n = 336), "discordant" if the only one did (n = 176), and "concordant" if both did (n = 66). Acute rejection (AR), graft failure, and BK nephropathy (BKN) were outcomes of interest. RESULTS: Donors in the concordant group were younger, had lower kidney donor profile index (KDPI), and were less likely to be donor after circulatory death (DCD). In multivariate analyses, KTRs who had a donor with a higher body mass index (BMI) (hazard ratio (HR): 0.97; 95% confidence interval (CI): 0.95-0.99; p = .009) were less likely to develop BKV. Concordance was not associated with AR (HR: 0.83; 95% CI: 0.51-1.34; p = .45), graft failure (HR: 1.77; 95% CI: 0.42-7.50; p = .43), or BKN (HR: 1.02; 95% CI: 0.51-2.03; p = .96). DISCUSSION: Our study suggests lower donor BMI is associated with BKV infection, and concordance or discordance between paired kidney recipients is not associated with poor outcomes.

Paraneoplastic cast nephropathy associated with malignant prolactinoma: A case report and literature review.

Malignant prolactinomas are very rare and are diagnosed when a prolactin-producing pituitary adenoma has metastasized. We report on a 54-year-old man with a history of macroprolactinoma transforming into a pituitary carcinoma secreting both prolactin and growth hormone with metastases to the stomach, bone, lungs, retroperitoneum, and kidney. Reviewing the literature, this case is the first reporting of a pituitary carcinoma with biopsy-proven paraneoplastic cast nephropathy. Symptoms and renal function improved following a course of palliative chemotherapy and radiotherapy. After 2 years, his disease progressed requiring further palliative treatment that was complicated by severe chest sepsis. He was not fit for further chemotherapy, receiving symptomatic relief in a hospice, and died soon after. The case highlights the importance of considering a patient's past medical history in the context of persistent unexplained renal impairment and systemic metastases when unexplained systemic symptoms and multi-organ involvement is present. The importance of renal biopsy for definitive diagnosis and before using potentially nephrotoxic chemotherapy is also highlighted. Renal diagnosis helped inform the decision to give chemotherapy, with the importance of this evidenced by an improvement in renal function following chemotherapy.

Incidence, risk factors, and outcomes of post-transplant erythrocytosis after kidney transplantation.

The incidence, risk factors, and outcomes of kidney transplant recipients (KTRs) with post-transplant erythrocytosis (PTE) in the modern era of strong, protocolized immunosuppressive management are unknown. In this study, we aim to identify the incidence and risk factors of PTE and outcomes associated with PTE. This study examined adult KTRs transplanted at our hospital between 01/2001 and 12/2016. Controls were KTRs without PTE and selected in a 1:5 ratio using incident density sampling. Patient survival, graft survival, and vascular thromboembolism (VTE) incidence were outcomes of interest. Of 4,317 kidney transplants during the study period, 214 (5%) had PTE and were compared with controls. In the multivariate analysis, recipients with older age (HR: 0.97, 95% CI 0.96-0.99, p = .001) were less likely to develop PTE, while male gender (HR: 3.2; 95% CI: 1.92-5.3, p < .001) and non-preemptive transplant (HR: 3.86, 95% CI 1.56-9.56, p = .003) were associated with increased risk of PTE. After adjustment for confounding factors, PTE was not associated with patient mortality (HR: 0.99, 95% CI 0.69-1.42, p = .97), graft failure (HR: 1.11, 95% CI 0.68-1.80, p = .69), or VTE (HR: 1.07, 95% CI 0.59-1.96, p = .81). The incidence of PTE is still substantial in this era, but with proper management PTE does not impact patient or graft survival.

Post-kidney transplant serum magnesium exhibits a U-shaped association with subsequent mortality: an observational cohort study.

Hypomagnesemia is common in kidney transplant recipients (KTRs). We sought to explore the relationship between Mg and outcomes in KTRs, which may be associated with mortality and thus may be a potential intervention target to improve outcomes. We followed KTRs performed between 01/2000 and 6/2016 at a large US transplant center from 6 months post-transplant to graft failure, death, or loss to follow-up. Using Mg as a time-dependent variable, associations between Mg and outcomes any time after 6 months post-transplant were evaluated. 3680 KTRs with 50  413 Mg measurements met inclusion criteria. 657 deaths occurred over a median follow-up of 5.1 years. Compared to Mg of 1.5-1.8 mg/dl, both lower (HR 1.17, 95% confidence interval (CI): 1.07-1.28) and higher (HR 1.16, 95% CI: 1.09-1.23) Mg levels were associated with greater risk of mortality. Similar U-shaped associations were observed for Mg and cardiovascular disease-related mortality (HR for Mg ≤1.5 mg/dl: 1.31; CI: 1.03-1.68) and infection-related mortality (HR for Mg ≤1.5 mg/dl: 1.28; CI: 1.09-1.51), although relationships for Mg >1.8 mg/dl were not statistically significant. Mg exhibits a U-shaped association with mortality in KTRs, with levels between 1.5 and 1.8 mg/dl associated with the lowest risk.

Successful management of T-cell mediated rejection in a recent kidney transplant recipient with COVID-19 associated severe acute respiratory syndrome.

COVID-19-associated vasculitis has been reported as a defining feature of systemic disease including acute kidney injury. However, the understanding of COVID-19 kidney transplant-related injuries is still evolving. We report a case of AKI with isolated vasculitis (v2 lesion) in a new kidney transplant recipient with COVID-19 pneumonia.

Risk factors for progression from low level BK dnaemia to unfavorable outcomes after BK management via immunosuppressive reduction.

BACKGROUNDS: Effective management of BK viremia (BKPyV-DNAemia) in kidney transplant recipients (KTRs) involves regular monitoring and adjustment of immunosuppression. With this strategy, the majority of patients will clear BK or have ongoing, but non-significant, low-level BKPyV-DNAemia. However, despite adjustments, some will develop more severe sequelae of BK including BKPyV-DNAemia >5 log10 copies/mL and BK nephropathy, and others may develop de novo DSA (dnDSA) or acute rejection (AR). METHODS: This was a single-center study of KTRs transplanted at the University of Wisconsin-Madison between 01/01/2015 and 12/31/2017. In this study, we sought to elucidate characteristics associated with the progression of BKPyV-DNAemia to unfavorable outcomes after decreasing immunosuppressive medications for the management of BK viremia as described in consensus guidelines. RESULTS: A total of 224 KTRs fulfilled our selection criteria; 118 (53%) resolved or had persistent low DNAemia, 64 (28%) had severe BK/nephropathy, and 42 (19%) developed dnDSA or AR. In multivariable analysis, female gender (HR: 2.05; 95% CI: 1.08-3.90; P = .02); previous rejection (HR: 2.90; 95% CI: 1.04-8.12; P = .04), and early infection (HR: 0.81; 95% CI: 0.72-0.90; P < .001) were associated with the development of severe BK/nephropathy. Conversely, non-depleting induction at transplant (HR: 2.06; 95% CI: 1.03-4.11; P = .03), HLA mismatches >3 (HR: 2.27; HR: 1.01-5.06; P = .04), and delayed graft function (HR: 4.14; 95% CI: 1.12-15.28; P = .03) were associated with development of dnDSA and/or rejection. CONCLUSION: Our study suggests that almost half of KTRs with BKPyV-DNAemia managed by our immunosuppressant adjustment protocol progress unfavorably. Identification of these risk factors could assist the frontline clinician in creating an individualized immunosuppressive modification plan potentially mitigating negative outcomes.

Cytomegalovirus nephritis in kidney transplant recipients: Epidemiology and outcomes of an uncommon diagnosis.

BACKGROUND: Data on epidemiology and outcomes of cytomegalovirus (CMV) nephritis in kidney transplant patients are limited due to the rarity of this condition. METHODS: A retrospective review of all kidney transplant recipients (KTR) (n = 6490) and biopsy-proven CMV nephritis between 1/1997 and 12/2020 was performed. RESULTS: The prevalence of CMV nephritis was low: 13/6490 (0.2%). The diagnosis was made at a median of 7.0 months (range 2.6-15.6 months) after transplant. 6 of 13 (46%) patients were CMV (D+/R-). Median CMV DNA load at biopsy was 376,000, IU/mL (range 87,000-6,460,000 IU/mL). Main biopsy features were CMV glomerulitis (n = 7/13, 54%) followed by CMV tubulointerstitial nephritis (6/13; 46%). Mean eGFR at biopsy (22.7 ± 12 mL/min/1.73 m2 ) was significantly decreased compared to baseline eGFR (38.7 ± 18.5 mL/min/1.73 m2 , p = 0.02). The vast majority, 11 of 13 (85%), experienced graft failure including 5 of 13 (38%) death-censored. 5 of 13 (38%) patients were diagnosed with acute rejection: three had concurrent acute rejection, and two had rejection within 3 months of index biopsy, respectively. Patients with tubulointerstitial CMV nephritis were significantly more likely to have rejection at the time of biopsy (50% vs. 0%, p < 0.05) compared to those with glomerular CMV nephritis. There were no significant differences between these groups in terms of eGFR at all time points, death, graft failure, immunosuppression changes or rejection after biopsy. CONCLUSION: CMV nephritis is rare but appears to be associated with poor patient/allograft outcomes. Early identification and timely treatment of CMV infection may prevent end-organ involvement and improve patient and allograft-related outcomes.

Obesity: An Independent Predictor of Morbidity and Graft Loss after Kidney Transplantation.

BACKGROUND: There is conflicting information on current medical and surgical complications associated with high body mass index (BMI) after kidney transplantation. METHODS: In a single-center observational study, we analyzed the 5-year outcomes of all consecutive primary kidney transplant recipients between 2010 and 2015 based on BMI at the time of transplant. RESULTS: There were 1,467 patients included in this study, distributed in the following groups based on BMI: underweight (n = 32, 2.2%), normal (n = 407, 27.7%), overweight (n = 477, 32.5%), grade I obesity (n = 387, 26.4%), grade II obesity (n = 155, 10.6%), and grade III obesity (n = 9, 0.6%). Obesity was associated with an increased incidence of delayed graft function (p = 0.008), length of stay (LOS, p = 0.03), 30-day surgical re-exploration (p = 0.02), and hospital readmission (p < 0.0001). Obesity was also associated with higher 1-year serum creatinine (p = 0.03) and increased 5-year incidence of cardiac events (p < 0.0001) and congestive heart failure (p < 0.0001). Multivariable Cox regression analyses determined grade III obesity (HR = 5.84, 95% CI: 1.40-24.36, p = 0.01), LOS >4 days (HR = 1.94, 95% CI: 1.19-3.18, p = 0.008), hospital readmission (HR = 2.25, 95% CI: 1.20-4.22, p = 0.01), 1-year serum creatinine >1.5 (HR = 1.95, 95% CI: 1.20-3.18, p = 0.007), and proteinuria (UPC) >1 g/g (HR = 1.85, 95% CI: 1.06-3.24, p = 0.03) as independent predictors of death-censored graft failure. CONCLUSION: In the current era of renal transplant care, obesity is common, and high BMI remains associated with significant medical and surgical complications after transplant.

Prevalence of primary aldosteronism in hypertensive kidney transplant recipients: A cross-sectional study.

Due to high prevalence of primary aldosteronism (PA) in the general hypertensive population, and its association with worse cardiovascular and renal outcomes, the 2016 Endocrine Society Guidelines explicitly recognize PA as a major public health issue requiring urgent attention. Its prevalence in hypertensive kidney transplant recipients (KTRs) is unknown. In this cross-sectional study, we screened KTRs with hypertension who were on ≥4 antihypertensive medications, on 3 antihypertensive medications with BP ≥ 140/90, and on potassium supplements, or were hypokalemic. 172 of 280 eligible patients successfully completed the testing. A positive screen for PA defined by an aldosterone-to-renin ratio of ≥20 and a plasma aldosterone concentration of >15 ng/dL yielded a prevalence of 15.7%. Potassium supplement requirement (52% vs 27%, P = .01) and hypokalemia (25.9% vs 4.8%, P < .01) were more common in patients who screened positive compared with those who screened negative. 67% of patients who screened positive were on potassium supplements and/or were hypokalemic. Our study is the first to systematically explore the prevalence of PA among the hypertensive KTR population, which has inherently high cardiovascular risk. Further studies are needed to determine the cardiovascular and renal risk attributable to PA, and define optimal therapy for KTRs with PA.
