Abstract
Late-onset hypogonadism is generally treated with testosterone replacement treatment. However, the efficacy rate of treatment for patients with low testosterone is not clear because patients without low testosterone are also treated in real-world clinical settings. This study comprised 110 men with low testosterone concentration of <3.0 ng/mL who underwent testosterone replacement treatment. Physical factors, laboratory and endocrinologic profiles, and scores of several questionnaires were assessed. Testosterone replacement treatment was performed with intramuscular injection of 250 mg of testosterone esters every 2-4 weeks, and efficacy was judged by patient satisfaction. After confirming efficacy, changes in several factors by the treatment were evaluated. Finally, the comparison between evaluation by patient satisfaction and by that with the questionnaires was assessed. Among the 110 patients, 77 (70.0%) were satisfied with the treatment, which was effective in 65.7%, 71.4%, and 73.1% of patients with mental, physical, and sexual dysfunction, respectively. The questionnaire scores including the Aging Males Symptoms rating scale were significantly improved in both the satisfaction and non-satisfaction group. However, no significant differences in the amount of change in questionnaire scores were found for all questionnaire scores improved by testosterone replacement treatment between the groups. Patient satisfaction was not associated with improvement of the Aging Males Symptoms score. Although testosterone replacement treatment was effective for 70.0% of the hypogonadal patients, patient satisfaction did not correlate with improvement of questionnaire scores. We concluded that not only questionnaire results but also patient satisfaction is important when evaluating efficacy in patients undergoing testosterone replacement treatment.

Abstract
OBJECTIVE To clarify the circadian rhythm of urination in hospitalized women with nocturia measured by toilet uroflowmetry and its age-related change. METHODS We evaluated 2602 urinations of 58 female patients (age, 68.4 ± 15.2 years) who were hospitalized in our institution for urological disease. We assessed voided volume (VV) as averages of every hour by generalized linear mixed models with an identity link function to adjust for personal bias and age. Maximum flow rate and voiding time were analyzed by the same method after adjustment for age, personal bias, and VV. We also compared these circadian rhythms between women <70 and ≥70 years. RESULTS VVs in the nighttime were significantly higher than that from 06:00-07:00 (205.6 ± 11.7 ml). Maximum flow rates in the afternoon were significantly higher than that from 06:00-07:00 (18.8 ± 0.93 ml/sec). Voiding time showed no statistically significant difference between the values at any time of day and that from 06:00-07:00. We also showed that the circadian rhythm of VV becomes less clear in the elderly women (P interaction = .0057). However, no significant difference was found in the maximum flow rate and voiding time regarding the pattern of the circadian rhythm between women <70 and ≥70 years old. CONCLUSION The present study clearly showed a circadian rhythm of VV and maximum flow rate in hospitalized women with nocturia. In addition, the pattern of the circadian rhythm of VV was attenuated in women ≥70 years old.

Abstract
INTRODUCTION Herein, we discuss clinicopathological analyses of cases of chronic renal allograft arteriopathy (CRA) after renal transplantation and clarify the mechanisms underlying the development and prognostic significance of CRA. METHODS CRA was diagnosed in 34 renal allograft biopsy specimens (BSs) obtained from 27 renal transplant patients who were followed up at the Department of Urology and Transplant Surgery, Toda Chuo General Hospital, between January 2010 and December 2020. RESULTS CRA was diagnosed at a median of 33.4 months post-transplantation. Of the 27 patients, 16 had a history of rejection. Among the 34 BSs showing evidence of CRA, CRA was mild (cv1 in Banff's classification) in 22, moderate (cv2) in 7, and severe (cv3) in 5 patients. We then classified the 34 BSs showing evidence of CRA based on their overall histopathological features as follows: cv alone seen in 11 (32%) BSs, cv + antibody-mediated rejection (AMR) in 12 (35%), and cv + T-cell-mediated rejection (TCMR) in 8 (24%). Loss of the renal allograft occurred during the observation period in 3 patients (11%). Of the remaining patients with functioning grafts, deterioration of renal allograft function after biopsies occurred in 7 cases (26%). CONCLUSIONS Our study results suggest that AMR contributes to CRA in 30-40% of cases, TCMR in 20-30% of cases, isolated v lesions in 15% of cases, and cv lesions alone in 30%. The intimal arteritis was a prognostic factor in CRA.

Abstract
BACKGROUND We report a case of suspected hyperacute rejection during living kidney transplantation. CASE REPORT A 61-year-old man underwent kidney transplantation in November 2019. Before the transplantation, immunologic tests revealed the presence of anti-HLA antibodies but not donor-specific HLA antibodies. The patient was intravenously administered 500 mg of methylprednisolone (MP) and basiliximab before perioperative blood flow reperfusion. After blood flow restoration, the transplanted kidney turned bright red and then blue. Hyperacute rejection was suspected. After the intravenous administration of 500 mg of MP and 30 g of intravenous immunoglobulin, the transplanted kidney gradually changed from blue to bright red. The initial postoperative urine output was good. On the 22nd day after the renal transplantation, the patient was discharged with a serum creatinine level of 2.38 mg/dL, and the function of the transplanted kidney gradually improved. CONCLUSIONS In this study, non-HLA antibodies may have been a cause of the hyperacute rejection, which was managed with additional perioperative therapies.

Abstract
Abstract
Introduction
Premature ejaculation (PE) has negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy. In Japan, no oral drugs or devices are approved or used clinically to treat PE. The Men’s Training Cup Keep Training (MTCK), a masturbation aid, was developed for PE. MTCK offers 5 grades of tightness and strength.
Aim
We aimed to investigate the efficacy of the MTCK in patients who are unable to delay ejaculation.
Methods
Inclusion criteria were 20- to 60-year-old men feeling distressed and frustrated by PE and who had the same sexual partners throughout the study period. Exclusion criteria were neurologic disease and uncontrolled diabetes mellitus, as well as the use of antidepressants, α-blockers, and 5α-reductase inhibitors. The protocol comprised an 8-week training period with the MTCK from level 1 to level 5, with each level used twice before moving to the next level.
Outcome Measures
The main outcome measure was the extension of intravaginal ejaculation latency time (IELT). The secondary outcome measures were score improvements on the Premature Ejaculation Diagnostic Tool, Sexual Health Inventory for Men, Erection Hardness Score, and Difficulty in Performing Sexual Intercourse Questionnaire–5.
Results
We enrolled 37 patients, and after 19 patients withdrew, 18 concluded the study without experiencing any adverse events. The mean patient age was 39.9 years. Geometric IELT after the 8-week training with the MTCK increased significantly (mean ± SE; 232.10 ± 72.16 seconds) vs baseline (103.91 ± 50.61 seconds, P = .006). Mean scores on the Premature Ejaculation Diagnostic Tool, Difficulty in Performing Sexual Intercourse Questionnaire–5, and Erection Hardness Score after 8-week training improved significantly vs the baseline values. The mean score on the Sexual Health Inventory for Men did not improve significantly after the 8-week training, but domain 1 did significantly improve after 8 weeks of MTCK use.
Clinical Implications
The MTCK may be one possible treatment option for patients who are unable to delay ejaculation.
Strengths and Limitations
This is the first study to show that the MTCK is effective for patients who are unable to delay ejaculation. A major limitation is that the present study was not strictly limited to an IELT <3 minutes.
Conclusions
The MTCK may offer benefits not only for delay of ejaculation but also for erectile function.

Abstract
OBJECTIVE To investigate the relation between serum zinc concentration and several factors, including serum testosterone concentration and the score of questionnaires on sexual function in patients with sexual problems. METHODS This study comprised 720 men (age, 46.3 [21-83] years) with some kind of sexual problem. Age, scores of the Sexual Health Inventory for Men and the Erection Hardness Score, and endocrinologic data including serum concentrations of testosterone, prostate-specific antigen, and zinc were included in this study. After serum zinc concentration of the men was classified into 5 groups (<70, 70≤ <80, 80≤ <90, 90≤ <100, ≤100 μg/dl), the relation of each parameter with serum zinc concentration was assessed for a trend analysis. Finally, the relation between serum concentrations of zinc and testosterone as well sexual function evaluated by the scores of the questionnaires was investigated. RESULTS Only serum testosterone concentration (ptrend = 0.028) and serum cortisol concentration (ptrend = 0.003) showed a statistically significant relation to serum zinc concentration by trend analysis. Interestingly, trend analysis between serum concentrations of testosterone and zinc still showed a significant association after adjustment for serum cortisol concentration (ptrend = 0.032). However, no significant association was found in the relation between serum zinc concentration and the scores of the questionnaires after adjustment for serum concentrations of testosterone and cortisol. CONCLUSION We clearly showed that after adjustment for serum cortisol concentration by trend analysis, serum testosterone concentration decreased as serum zinc concentration decreased, although sexual symptoms were not associated with this decrease.

Abstract
PURPOSE Although patients with late-onset hypogonadism (LOH) often experience lower urinary tract symptoms (LUTS), LUTS are not generally included in LOH symptoms. No study has examined the direct relation of the Aging Males Symptoms rating scale (AMS) and the International Prostate Symptom Score (IPSS) with the quality of life (QOL) index. We analyzed the relation between the IPSS and QOL index and various factors including the AMS in patients with LOH syndromes. MATERIALS AND METHODS This study comprised 1,688 men with LOH symptoms who visited our hospital or affiliated clinic. Factors associated with the IPSS were assessed in terms of age, scores of several questionnaires including the AMS, endocrinological variables, and serum concentration of PSA. Among these same factors, those associated with the QOL index were also evaluated. Finally, the same analyses were repeated in 187 patients with low serum testosterone concentration (<3.0 ng/mL). RESULTS In a multivariate analysis using the significant items from the univariate analysis, AMS, age, and Erection Hardness Score correlated significantly with the IPSS. A trend analysis using items other than the AMS as adjustment factors also confirmed the relationship between an increase in QOL index and an increase in AMS. Similar results were obtained in the analysis of patients with low serum testosterone concentration. CONCLUSIONS We revealed that the relation of IPSS with the QOL index for LUTS is closely associated with the AMS for LOH, regardless of testosterone level. When patients complain of LOH symptoms, a careful, detailed inquiry into LUTS is required.

Abstract
Purpose There are no approved drugs or devices for the treatment of intravaginal ejaculation disorders, and treatment is often difficult. This study aimed to evaluate the efficacy and safety of the A10 Cyclone SA + PLUS® ejaculation aid (Rends Co., Ltd., Chiba, Japan), which allows the user to adjust the intensity of stimulation, for intravaginal ejaculation disorders. Methods Each participant was instructed to perform practice masturbation with the A10 Cyclone SA + PLUS to simulate vaginal ejaculation. After 8 weeks of training, the participants were asked about their intravaginal ejaculation status. Sexual function was also evaluated before and after the training using several specific questionnaires, including the numerical rating scale for ejaculatory satisfaction. Results Among the 10 participants (41.5 ± 3.21 years) who completed the training and questionnaire evaluation, four (40%) became capable of intravaginal ejaculation. The questionnaire evaluation showed predominant improvement after training in the ejaculation-capable group according to the numerical rating scale, which expresses satisfaction with ejaculation. The participants experienced no significant adverse events. Conclusion As no effective treatment currently exists for intravaginal ejaculation disorders, we conclude that the A10 Cyclone SA + PLUS may be one treatment tool for intravaginal ejaculation disorders with good efficacy and no adverse events.

Abstract
OBJECTIVES To clarify the efficacy of low-intensity extracorporeal shockwave therapy for patients with erectile dysfunction, compare the efficacy between two types of lithotripters (ED1000 [focused type] and Renova [linear type]), and detect factors indicative of therapeutic gain with the treatment. METHODS This retrospective study included 76 patients (52.8 ± 11.7 years) treated by ED1000 (12 times over 9 weeks) and 484 patients (52.5 ± 11.6 years) treated by Renova (4 times over 4 weeks). Age, sexual symptoms scores, and blood examinations were assessed. Efficacy was judged by improvement of the scores and patient satisfaction and compared between patients at 1 month after treatment with the lithotripters. Independent factors influencing efficacy by Renova were also assessed. RESULTS Sexual symptom scores were improved significantly by both lithotripters, although the changes in the scores did not differ significantly between them. Efficacy rate as judged by patient satisfaction was 65.8% with the ED1000 and 71.1% with Renova, also without significant difference. Among several factors including age, sexual symptoms scores, endocrinological factors, metabolic factors, and the rate of phosphodiesterase type 5 inhibitor use, only age was found to be an independent factor influencing the efficacy of Renova. CONCLUSION We clearly showed the high efficacy of both lithotripters. Although the efficacy rate did not differ between them, we speculated that the fewer treatment sessions needed with the Renova versus the ED1000 would be a great advantage for patients. We also suggest that Renova should be recommended for patients younger than 70 years of age.

Abstract
Late-onset hypogonadism (LOH) is generally treated with testosterone replacement therapy. Intramuscular injection of testosterone enanthate is used for LOH in Japan but requires regular painful injections administered every 2-3 weeks at a clinic. Testosterone 2% (AndroForte 2® [AF2]) is available for treating LOH but is expensive because it is imported. We developed a new 2% testosterone gel (NTG) and hypothesized that in patients with LOH, NTG would improve serum testosterone concentrations and Aging Males' Symptoms (AMS) scores compared with AF2. We enrolled men with low levels of serum free testosterone (<11.8 pg/mL) and androgen deficiency symptoms (AMS score >27). The primary endpoint was equivalent change in serum testosterone concentrations with NTG compared to AF2. Secondary endpoints were equivalent change in AMS scores for each question with NTG compared to AF2. Each of AF2 or NTG was administered to the study subjects (23 men aged 42-71 years) for 4 weeks separated by a washout period of 2 weeks. The subjects were randomly divided into men who first received NTG and those who first received AF2. No subject experienced any adverse events throughout the study. Compared with the baseline values of serum testosterone, those following NTG and AF2 treatment were significantly higher and were also significantly higher in the subjects taking NTG versus AF2. NTG administration significantly improved the AMS score, whereas AF2 did not. This initial study has shown that this new NTG formulation may be effective in improving serum testosterone concentrations and also LOH-related symptoms.

Abstract
In this study, we performed a year-long in situ incubation experiment on a common ferrous sulfide (Fe-S) mineral, pyrite, at the oxidative deep seafloor in the hydrothermal vent field in the Izu-Bonin arc, Japan, and characterized its microbiological and biogeochemical properties to understand the microbial alteration processes of the pyrite, focusing on Fe(II) oxidation. The microbial community analysis of the incubated pyrite showed that the domain Bacteria heavily dominated over Archaea compared with that of the ambient seawater, and Alphaproteobacteria and Gammaproteobacteria distinctively codominated at the class level. The mineralogical characterization by surface-sensitive Fe X-ray absorption near-edge structure (XANES) analysis revealed that specific Fe(III) hydroxides (schwertmannite and ferrihydrite) were locally formed at the pyrite surface as the pyrite alteration products. Based on the Fe(III) hydroxide species and proportion, we thermodynamically calculated the pH value at the pyrite surface to be pH 4.9 to 5.7, indicating that the acidic condition derived from pyrite alteration was locally formed at the surface against neutral ambient seawater. This acidic microenvironment at the pyrite surface might explain the distinct microbial communities found in our pyrite samples. Also, the acidity at the pyrite surface indicates that the abiotic Fe(II) oxidation rate was much limited at the pyrite surface kinetically, 3.9 × 103- to 1.6 × 105-fold lower than that in the ambient seawater. Moreover, nanoscale characterization of microbial biomolecules using carbon near-edge X-ray absorption fine-structure (NEXAFS) analysis showed that the sessile cells attached to pyrite excreted the acidic polysaccharide-rich extracellular polymeric substances at the pyrite surface, which can lead to the promotion of biogenic Fe(II) oxidation and pyrite alteration. IMPORTANCE Pyrite is one of the most common Fe-S minerals found in submarine hydrothermal environments. Previous studies demonstrated that the Fe-S mineral can be a suitable host for Fe(II)-oxidizing microbes in hydrothermal environments; however, the details of microbial Fe(II) oxidation processes with Fe-S mineral alteration are not well known. The spectroscopic and thermodynamic examination in the present study suggests that a moderately acidic pH condition was locally formed at the pyrite surface during pyrite alteration at the seafloor due to proton releases with Fe(II) and sulfidic S oxidations. Following previous studies, the abiotic Fe(II) oxidation rate significantly decreases with a decrease in pH, but the biotic (microbial) Fe(II) oxidation rate is not sensitive to the pH decrease. Thus, our findings clearly suggest that the pyrite surface is a unique microenvironment where abiotic Fe(II) oxidation is limited and biotic Fe(II) oxidation is more prominent than that in neutral ambient seawater.

Abstract
BACKGROUND Patients undergoing organ transplantation are immunosuppressed and already at risk of various diseases. We report about a patient who underwent ABO-incompatible kidney transplantation after coronavirus disease 2019 (COVID-19) without a recurrence of infection. CASE REPORT A 68-year-old woman presented with end-stage renal failure owing to primary autosomal dominant polycystic kidney disease; accordingly, hemodialysis was initiated in September 2020. Her medical history included bilateral osteoarthritis, lumbar spinal stenosis, hypertension, and hyperuricemia. In mid-January 2021, she contracted severe acute respiratory syndrome coronavirus 2 infection from her husband. Both of them were hospitalized and received conservative treatment. Because their symptoms were mild, they were discharged after 10 days. The patient subsequently underwent ABO-incompatible kidney transplantation from her husband who recovered from COVID-19 in March 2021. Before kidney transplantation, her COVID-19 polymerase chain reaction test was negative, confirming the absence of pre-existing COVID-19 immediately before the procedure. Computed tomography revealed no pneumonia. Initial immunosuppression was induced by administering tacrolimus, mycophenolate mofetil, methylprednisolone, basiliximab, rituximab, and 30 g of intravenous immunoglobulin. Double-filtration plasmapheresis and plasma exchange were performed once before ABO-incompatible kidney transplantation. The renal allograft functioned immediately, and the postoperative course was normal without rejection. COVID-19 did not recur. In addition, her serum creatinine levels and renal function had otherwise remained stable. CONCLUSION Living kidney transplantation was safely performed in a patient with COVID-19 without postoperative complications or rejection. During the COVID-19 pandemic, the possibility of severe acute respiratory syndrome coronavirus 2 infection during transplantation surgery must be considered.

Abstract
PURPOSE Sexuality is very important for men's health. Currently, phosphodiesterase type 5 inhibitors (PDE5i) remain the first-line therapy for erectile dysfunction, and no other oral drugs or drinks are approved and used clinically to treat male libido or orgasm dysfunction. In reference to a pharmaceutical dosage document, growing health consciousness is said to have boosted yearly sales of supplement drinks to more than 170 billion yen (1.58 billion US dollars) in Japan. We have created a supplement drink comprised of testofen, L-citrulline, resveratrol, and caffeine. We hypothesized that our supplement drink would be effective for men with sexual dysfunction, and especially libido dysfunction. MATERIALS AND METHODS In this study, men with sexual dysfunction received a placebo drink for 14 days or our supplement drink (testofen, 600 mg/d; L-citrulline, 800 mg/d; resveratrol, 300 mg/d; and caffeine, 40 mg/d) for another 14 days separated by a 7-day washout period. Patients continued on-demand use of PDE5i. The International Index of Erectile Function (IIEF) score and adverse events were assessed. RESULTS Twenty patients aged 30-7 years old were enrolled in and concluded the study with no adverse events experienced. The IIEF domains of desire frequency, erection frequency, erection firmness, erection confidence, intercourse satisfaction, ejaculation frequency, orgasm frequency, and overall satisfaction were significantly improved with our supplement drink. CONCLUSIONS This is the first study to show that our supplement drink may not only be effective for erection but also for libido, orgasm, and ejaculation.

Abstract
OBJECTIVE To investigate the efficacy and safety of vibegron add-on therapy in men with persistent storage symptoms receiving α-1 blockers or PDE5 inhibitor for benign prostatic hyperplasia and then determine the independent factors affecting the efficacy of vibegron. METHODS Vibegron 50 mg was administered for 12 weeks to 42 patients (72.0 ± 8.2 years) with persistent storage symptoms who had taken α-1 blockers (22 patients) or PDE5 inhibitor (20 patients). The primary endpoint was change in the overactive Bladder (OAB) Symptom Score from baseline to end of treatment. The secondary endpoints were changes in each question of several questionnaires, maximum flow rate and residual urine volume. Finally, independent factors affecting the efficacy of vibegron were investigated. RESULTS Total OAB Symptom Score was significantly decreased (6.21 ± 3.12 vs 4.38 ± 2.46; P < .001). Although each score of several questionnaires, especially for storage symptoms, improved significantly, no significant improvement was found in stress incontinence, straining, bladder pain and urethral pain in the Core Lower Urinary Tract Symptom score. Maximum flow rate and residual urine volume did not change, and no patient discontinued vibegron because of adverse events. Multiple regression analysis showed that OAB Symptom Score, Core Lower Urinary Tract Symptom score, prostate volume and monotherapy with α-1 blocker were independent factors affecting the efficacy of vibegron. CONCLUSION Add-on therapy of vibegron to monotherapy with α-1 blockers or PDE5 inhibitor for patients with benign prostatic hyperplasia and persistent storage symptoms was effective and safe.

Abstract
BACKGROUND AND PURPOSE Obtaining information on invisible vasculature distal to the occlusion site helps to deploy a stent retriever safely during mechanical thrombectomy for large-vessel occlusion. It is essential to reduce the amount of contrast used for detecting the vessels distal to the occlusion site because acute ischemic stroke patients tend to have chronic kidney disease and patients with severe chronic kidney disease are at an increased risk of contrast-associated acute kidney injury. We assessed whether vessels distal to the occlusion site during acute ischemic stroke with large-vessel occlusion could be visualized on angiographic images using flat panel detector CT acquired following intra-arterial diluted contrast injection, compared with MRA findings. MATERIALS AND METHODS Between May 2019 and January 2020, we enrolled 28 consecutive patients with large-vessel occlusions of the anterior circulation eligible for mechanical thrombectomy following MR imaging. The patients underwent CBV imaging using flat panel detector CT with an intra-arterial diluted contrast injection instead of intravenous injection. Flat panel detector CT angiographic images reconstructed from the same dataset were evaluated for image quality, collateral status of the MCA territory, and visualization of the vessels distal to the occlusion site. These findings were compared with MRA findings. RESULTS Twenty-two patients were retrospectively examined. Flat panel detector CT angiographic image quality in 20 patients (91%) was excellent or good. The distal portion of the occluded vessel segment was visualized in 14 patients (70%), while the proximal portion of the segment adjacent to the occluded vessel in 3 (15%) was visualized. No visualization was observed in only 1 patient (5%) with no collateral supply. Flat panel detector CT angiographic images were shown to evaluate vessels distal to the occlusion site more accurately than MRA. CONCLUSIONS In acute ischemic stroke with large-vessel occlusion, flat panel detector CT angiographic images could successfully visualize vessels distal to the occlusion site with a small amount of contrast material.

Variables assessed in the study were: age; symptomatic scores, including sexual function evaluated using several specific questionnaires; endocrinological profiles, especially follicle-stimulating hormone; and serum zinc concentrations. Based on World Health Organization criteria for assessing sperm quality, semen volume ≥1.5 mL, sperm concentration ≥15 million/mL, or sperm motility rate ≥40%, the men were grouped according to whether they had values below or above these criteria. The two groups were compared with regard to the study variables, and correlation between serum zinc concentration and semen quality was evaluated. Independent predictors for inclusion in the group with values below the criteria were investigated further. RESULTS Of the 217 men included in the study, 45 (20.7%) were categorized as having values below the World Health Organization criteria. The men in this group were significantly older and had significantly worse sexual function, significantly higher follicle-stimulating hormone levels, and significantly lower serum zinc concentrations, than those in the group with values above the criteria. There was no significant correlation between serum zinc concentration and semen quality. However, the independent predictors for having values below the criteria in binomial logistic regression analysis were follicle-stimulating hormone and serum zinc concentration. CONCLUSION We suggest that semen analysis may be considered in men with a low level of serum zinc and high level of follicle-stimulating hormone when developing a life plan for fertilization.

Abstract
OBJECTIVES To investigate the prevalence of testicular microlithiasis and the relationship between testicular microlithiasis, semen parameters and endocrinological profiles in healthy newlywed men trying for first-time pregnancy. METHODS Men visiting Juntendo University Urayasu Hospital, Urayasu, Chiba, Japan, or D Clinic Tokyo, Chiyoda-ku, Tokyo, Japan, for a first-time examination of fertility underwent scrotal examination, semen analysis and blood tests. Testicular volume measured by orchidometer, semen parameters measured by the Makler counting chamber and endocrinological profiles were compared between men with testicular microlithiasis and without testicular microlithiasis. The correlation between sperm concentration and the number of calcifications, and sperm motility and the number of calcifications, were investigated. RESULTS Of 739 men, 60 (8.1%) were diagnosed as having testicular microlithiasis. Among them, testicular volume, semen volume and motility were lower than those in the men without testicular microlithiasis. Luteinizing hormone and follicle-stimulating hormone levels were higher in those with than those without testicular microlithiasis. The sperm concentration correlated negatively with the number of calcifications. There was no significant correlation between sperm motility and the number of calcifications. CONCLUSION Herein, we report the prevalence of testicular microlithiasis in healthy newlywed men. Furthermore, our findings suggest that semen parameters in men with severe testicular microlithiasis tend to be worse.

Abstract
OBJECTIVES To define the characteristics of patients with late-onset hypogonadism based on endocrinological findings. METHODS We assessed age, body mass index, laboratory/endocrinological profiles and symptom-specific questionnaire scores of 967 men with late-onset hypogonadism symptoms. The patients comprised four groups by testosterone and luteinizing hormone concentrations: normal group, compensated hypogonadism group, primary hypogonadism group and secondary hypogonadism group. We compared characteristics between the normal group and compensated hypogonadism group in men with normal testosterone concentration, and the primary hypogonadism group and secondary hypogonadism group in hypogonadal men after age adjustment. RESULTS The normal group, compensated hypogonadism group, primary hypogonadism group and secondary hypogonadism group accounted for 83.6%, 3.4%, 0.8% and 12.2% of patients, respectively. Despite age adjustment, serum dehydroepiandrosterone sulfate and insulin-like growth factor 1 concentrations were significantly lower in the compensated hypogonadism group than the normal group. Only the Aging Males' Symptoms scale mental subscore was significantly different. Serum testosterone and dehydroepiandrosterone sulfate concentrations were significantly lower in the primary hypogonadism group than the secondary hypogonadism group. Only the Aging Males' Symptoms scale sexual subscore was significantly different. CONCLUSIONS Most patients with late-onset hypogonadism symptoms are in the normal group, with secondary hypogonadism being much more frequent than primary hypogonadism. Current symptomatic differences among these groups are minor. Classifying patients by testosterone and luteinizing hormone levels might provide useful information for follow up.

Abstract
Introduction As a continuous decline in semen concentration has been reported, the concept of male infertility has gained increased attention. Although several surveys of semen quality have been conducted in young men in general, no study has reported only on newlywed men. Aim The aim of this study was to evaluate semen quality and assess its characteristics in newlywed men. Methods This study included 564 men visiting our hospital or clinic for fertility screening just before their wedding or as newlywed men. Based on the World Health Organization criteria, the rates of men who did not have a semen volume of ≥1.5 mL, a sperm concentration of ≥15 million/mL, and a sperm motility rate of ≥40% were calculated. The characteristics of the poor semen findings group with any 1 of the 3 items of semen volume, sperm concentration, or sperm motility rate not reaching the reference value were evaluated. Main Outcome Measure Independent factors, which are involved in the poor semen findings group, were evaluated. Results The poor findings in semen volume, sperm concentration, and sperm motility were found in 11.0%, 9.2%, and 10.6%, respectively. The poor semen findings group included 143 men (25.4%) with any 1 of the 3 items not reaching the reference value. As compared to the normal group, age and body mass index were significantly higher, testicular volume was significantly smaller, and blood gamma-glutamyltransferase and fasting blood sugar levels were significantly higher in the poor semen findings group. Logistic multivariate analysis, including symptom questionnaire scores, blood biochemistry items, and endocrinological items, showed 3 independent factors were involved in the poor semen findings group: age, luteinizing hormone, and erection (Erection Hardness Score). Conclusion It was clarified that even among men beginning their attempts at pregnancy, semen findings were poor and erectile dysfunction was involved in poor semen quality in one-quarter of the men.

Abstract
OBJECTIVES To investigate the efficacy of tadalafil for patients with benign prostatic hyperplasia and chronic prostatitis/chronic pelvic pain syndrome. METHODS Tadalafil 5 mg was given each morning for 12 weeks to patients diagnosed as having either moderate or severe lower urinary tract symptoms. Voiding symptoms were compared between patients with a high (≥4; high group) and low (<4; low group) pain subscore of the National Institutes of Health Chronic Prostatitis Symptom Index before and after tadalafil administration. The correlation between changes in the Chronic Prostatitis Symptom Index and the International Prostate Symptom Score during treatment was also investigated. RESULTS At baseline, the pain subscore of the Chronic Prostatitis Symptom Index was high (≥4) in 24 of 74 (32.4%) patients. The International Prostate Symptom Score in the group with a high pain subscore was significantly higher than that in the group with a low pain subscore. International Prostate Symptom Score, National Institutes of Health Chronic Prostatitis Symptom Index total score and pain subscore were all significantly improved after treatment. The change in the Chronic Prostatitis Symptom Index total score correlated positively with the change in the International Prostate Symptom Score. The decrease in the International Prostate Symptom Score was significantly greater in the group with high versus low pain subscore. CONCLUSIONS Tadalafil is sufficiently effective in the treatment of patients with benign prostatic hyperplasia and severe chronic prostatitis/chronic pelvic pain syndrome.

Abstract
PURPOSE The direct effects of Lepidium meyenii (Maca) on sperm remain unclear. Herein, we examined the direct effect of Maca on in vitro fertilization. METHODS We examined the fertilization rate in a mouse model and the rate of acrosome reaction in sperm from transgenic mice expressing enhanced green fluorescent protein (EGFP) in a Maca extract-containing human tubal fluid (HTF) medium. Using human sperm, we assessed acrosome status via fluorescein isothiocyanate-conjugated peanut agglutinin (FITC-PNA) staining and performed detailed analysis using a sperm motility analysis system (SMAS). RESULTS In the mouse model, the fertilization rate in the Maca extract-containing HTF was significantly higher than that in the control medium. The acrosome reaction rate in sperm from transgenic mice expressing EGFP was also significantly higher in the Maca extract-containing HTF than that in the control medium. Similarly, a high acrosome reaction rate, identified via FITC-PNA staining of human sperm samples, was found in the Maca extract-containing HTF compared with that in the control medium. Human sperm motility in the Maca extract-containing HTF was also increased compared with that in the control medium as measured using an SMAS. CONCLUSIONS Maca improved in vitro fertilization rates by inducing an acrosome reaction and increasing sperm motility.

Abstract
INTRODUCTION Phosphodiesterase type 5 inhibitors (PDE5i) are first-line therapy for most men with erectile dysfunction (ED). If ineffective, vacuum erection devices, intracavernous injections, and penile prosthesis implantation are suitable as second- or third-line therapies. However, very few patients select these therapies. It is critically important to improve erectile function with oral administration of effective agents. Administration of L-citrulline or transresveratrol in animal experiments has been reported to improve erectile function, but few such experiments have been performed on humans with ED. AIM We aimed to investigate the efficacy of combination therapy of L-citrulline and transresveratrol in patients with ED despite their use of PDE5i. METHODS In this randomized, double-blind, placebo-controlled crossover pilot study, men with ED (Sexual Health Inventory for Men [SHIM] score below 16) despite on-demand use of PDE5i received a placebo for 1 month or the active treatment (L-citrulline 800 mg/day and transresveratrol 300 mg/day) for another month. Patients continued on-demand use of PDE5i. MAIN OUTCOME MEASURE The SHIM score, Erection Hardness Score (EHS), Aging Male Symptoms Scale-sexual domain (AMS-SD), and adverse events were examined. RESULTS 20 patients ages 29-78 years were enrolled, and after 6 men withdrew, 13 concluded the study without adverse events. Mean SHIM score for the active treatment increased significantly (10.96 ± 1.21) compared with baseline (8.32 ± 1.21) and placebo (8.31 ± 1.23) (both P < .05). Mean EHS score for the active treatment (2.56 ± 0.26) also increased from baseline (2.31 ± 0.26), but not significantly (P = .79). Mean AMS-SD score was not significantly different in either group. CONCLUSION To our knowledge, this is the first study to show that combination therapy of L-citrulline and transresveratrol is effective for ED treatment in men with added on-demand use of PDE5i. This combination supplement may be added if PDE5i is insufficient. Shirai M, Hiramatsu I, Aoki Y, et al.

Abstract
Recently, perpendicular magnetic anisotropy (PMA) and its voltage control (VC) was demonstrated for Cr/Fe/MgO. In this study, we shed light on the origin of large voltage-induced anisotropy change in Cr/Fe/MgO. Analysis of the chemical structure of Cr/Fe/MgO revealed the existence of Cr atoms in the proximity of the Fe/MgO interface, which can affect both magnetic anisotropy (MA) and its VC. We showed that PMA and its VC can be enhanced by controlled Cr doping at the Fe/MgO interface. For Cr/Fe (5.9 Å)/Cr (0.7 Å)/MgO with an effective PMA of 0.8 MJ/m3, a maximum value of the voltage-controlled magnetic anisotropy (VCMA) effect of 370 fJ/Vm was demonstrated due to Cr insertion.

Abstract
BACKGROUND Chronic prostatitis (CP) significantly worsens a patient's quality of life (QOL), but its etiology is heterogeneous. Although the inflammatory process must be associated with CP symptoms, not all patients with benign prostatic hyperplasia and histological prostatitis complain of CP symptoms. The relation between the severity of histological inflammation and lower urinary tract symptoms (LUTS) and erectile function is not fully understood. METHODS This study comprised 26 men with suspected prostate cancer but with no malignant lesion by pathological examination of prostate biopsy specimens. LUTS were assessed by several questionnaires including the International Prostate Symptom Score (IPSS), QOL index, Overactive Bladder Symptom Score (OABSS), and the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), and erectile function was assessed by the Sexual Health Inventory for Men. Prostate volume (PV) measured by transabdominal ultrasound, maximum flow rate by uroflowmetry, and serum concentration of prostate-specific antigen were also evaluated. All data collections were performed before prostate biopsy. Histological prostatitis was assessed by immunohistochemical staining with anti-CD45 antibody as the Quick score. The relation between the Quick score and several factors was assessed by Pearson correlation coefficient and a multivariate linear regression model after adjustment for PV. RESULTS The Pearson correlation coefficient showed a correlation between the Quick score and several factors including PV, IPSS, QOL index, OABSS, and NIH-CPSI. A multivariate linear regression model after adjustment for PV showed only the NIH-CPSI to be associated with the Quick score. The relation between the Quick score and each domain score of the NIH-CPSI showed only the subscore of urinary symptoms to be an associated factor. CONCLUSION We found a correlation only between histological prostatitis and LUTS, but not erectile dysfunction. Especially, the subscore of urinary symptoms (residual feeling and urinary frequency) was associated with histological prostatitis.

Abstract
Background Atherosclerosis is a systematic disease in which plaque builds up inside the arteries that can lead to serious problems related to quality of life (QOL). Lower urinary tract symptoms (LUTS), erectile dysfunction (ED), and late-onset hypogonadism (LOH) are highly prevalent in aging men and are significantly associated with a reduced QOL. However, few questionnaire-based studies have fully examined the relation between atherosclerosis and several urological symptoms. Materials and methods The study comprised 303 outpatients who visited our clinic with symptoms of LOH. Several factors influencing atherosclerosis, including serum concentrations of triglyceride, fasting blood sugar, and total testosterone measured by radioimmunoassay, were investigated. We also measured brachial-ankle pulse wave velocity (baPWV) and assessed symptoms by specific questionnaires, including the Sexual Health Inventory for Men (SHIM), Erection Hardness Score (EHS), International Prostate Symptom Score (IPSS), QOL index, and Aging Male Symptoms rating scale (AMS). Stepwise associations between the ratio of measured/age standard baPWV and clinical factors including laboratory data and the scores of the questionnaires were compared using the Jonckheere–Terpstra test for trend. The associations between the ratio of measured/age standard baPWV and each IPSS score were assessed in a multivariate linear regression model after adjustment for serum triglyceride, fasting blood sugar, and total testosterone. Results Regarding ED, a higher level of the ratio of measured/age standard baPWV was associated with a lower EHS, whereas no association was found with SHIM. Regarding LUTS, a higher ratio of measured/age standard baPWV was associated with a higher IPSS and QOL index. However, there was no statistically significant difference between the ratio of measured/age standard baPWV and AMS. A multivariate linear regression model showed only nocturia to be associated with the ratio of measured/age standard baPWV for each IPSS score. Conclusion Atherosclerosis is associated with erectile function and LUTS, especially nocturia.

Abstract
Foodborne disease outbreaks caused by raw olive flounders (Paralichthys olivaceus) parasitized with Kudoa septempunctata have been reported in Japan. Origins of olive flounders consumed in Japan vary, being either domestic or imported, and aquaculture-raised or natural. Although it is unknown whether different sources are associated with different outcomes, it is desirable to identify whether this is the case by determining whether unique K. septempunctata strains occur and if so, whether some are associated with foodborne illness. We here developed an intraspecific genotyping method, using the sequence variation of mitochondrial genes. We collected olive flounder samples from foodborne disease outbreaks, domestic fish farms or quarantine offices and investigated whether K. septempunctata genotype is associated with pathogenicity or geographic origin. The 104 samples were classified into three genotypes, ST1, ST2 and ST3. Frequency of symptomatic cases differed by genotypes, but the association was not statistically significant. Whereas K. septempunctata detected from aquaculture-raised and natural fish from Japan were either ST1 or ST2, those from fish inspected at quarantine from Korea to Japan were ST3. Our method can be applied to phylogeographic analysis of K. septempunctata and contribute to containing the foodborne disease. The genotype database is hosted in the PubMLST website (http://pubmlst.org/kseptempunctata/).

Abstract
BACKGROUND Although the serum adiponectin level is inversely correlated to body mass index and closely associated with obesity and related diseases, neither the impact of weight loss on the adiponectin level nor other factors that might influence the adiponectin level during weight loss intervention are well documented. OBJECTIVE The objective of the study is to assess the change in the serum adiponectin level during weight loss intervention and to determine if sleep parameters affect the serum adiponectin level. METHODS Ninety women with overweight or obesity aged 25 to 65 years completed a 7-month cognitive behavioural therapy based weight loss intervention that included dieting, exercise and stress management. Serum adiponectin level, body fat percent, symptoms of depression and anxiety and objective sleep parameters, assessed by actigraphy, were measured at baseline and at the end of the intervention. RESULTS The serum adiponectin level was significantly increased after the weight loss intervention (P < 0.001). In a multiple regression analysis, the change of the adiponectin level was positively associated with the magnitude of body fat loss (β = -0.317, P < 0.001) and an increase of sleep minutes (β = 0.210, P = 0.043). CONCLUSION An increase in objective sleep duration was related to a significantly increased serum adiponectin level independently of the change of body fat during the weight loss intervention.

Abstract
ABO-incompatible living kidney transplantation (ABO-ILKT) has steadily become more widespread. However, the optimal immunosuppressive regimen for ABO-ILKT remains uncertain. We aimed to determine the longitudinal changes in the outcomes from ABO-ILKT compared with those from ABO-compatible living kidney transplantation (ABO-CLKT) over the last 25 years. Of 1195 patients who underwent living kidney transplantations (LKT) at our institute between 1989 and 2013, 1032-including 247 ABO-ILKT and 785 ABO-CLKT cases-were evaluated for graft survival, patient survival, infectious adverse events, and renal function. The patients were divided into four groups according to the transplantation era and ABO-compatibility. In the past decade, ABO-ILKT and ABO-CLKT recipients yielded almost equivalent outcomes with respect to the 9-year graft survival rates, which were 86.9% and 92.0%, respectively (hazard ratio [HR] 1.38, 95% confidence interval [CI] 0.59-3.22, p = 0.455). The graft survival rate for ABO-ILKT conducted between 2005 and 2013 was better than that for ABO-ILKT conducted between 1998 and 2004 (HR 0.30, 95% CI 0.13-0.72, p = 0.007). ABO-ILKT recipients showed substantial improvements in the graft survival rate over time. Graft survival was almost identical over the past decade, regardless of ABO-incompatibility. Currently, ABO-ILKT is an acceptable treatment for patients with end-stage renal disease.

The purpose of this study is to examine whether postoperative antiblood type antibody rebound is attributed to kidney allograft rejection in ABO blood type-incompatible (ABO-I) living-related kidney transplantation (KTx). A total of 191 ABO-I recipients who received ABO-I living-related KTx between 2001 and 2013 were divided into two groups: Group 1 consisted of low rebound [(≦1:32), N = 170] and Group 2 consisted of high rebound [(≧1:64), N = 21], according to the levels of the rebounded antiblood type antibodies within 1 year after transplantation. No prophylactic treatment for rejection was administered for elevated antiblood type antibodies, regardless of the levels of the rebounded antibodies. Within 1 year after transplantation, T-cell-mediated rejection was observed in 13 of 170 recipients (13/170, 8%) in Group 1 and in 2 of 21 recipients (2/21, 10%) in Group 2 (Groups 1 vs. 2, P = 0.432). Antibody-mediated rejection was observed in 15 of 170 recipients (15/170, 9%) and 2 of 21 recipients (2/21, 10%) in Groups 1 and 2, respectively (P = 0.898). In this study, we found no correlation between the postoperative antiblood type antibody rebound and the incidence of acute rejection. We concluded that no treatment is necessary for rebounded antiblood type antibodies.

Abstract
We investigated the relationship between preoperative anti-HLA antibodies (donor-specific antibody, DSA) and the graft survival rate in recipients who had or had not received rituximab (Rit) treatment. The subjects were categorized into four groups as follows: DSA+Rit-, n = 39; DSA-Rit-, n = 121; DSA+Rit+, n = 74; and DSA-Rit+, n = 47. We examined the influence of preoperative DSA on the incidence of graft rejection and the survival rate of recipients who had or who had not received rituximab before transplantation. The 6-month acute rejection rates based on graft biopsies were 39%, 19%, 15%, and 0% for the DSA+Rit-, DSA-Rit-, DSA+Rit+, and DSA-Rit+ groups. The rates of chronic antibody-mediated rejection after more than 6 months were 50%, 22%, 18%, and 0%. The 5-year graft survival rate was significantly lower in the DSA+Rit- group (84%) than in the other groups (95% for DSA-Rit-, 98% for DSA+Rit+, and 91% for DSA-Rit+). The rate of the appearance of de novo anti-HLA antibodies was higher in the groups that did not receive rituximab treatment. The rate of graft loss associated with chronic antibody-mediated rejection was also higher in the DSA+Rit- group than in the other groups (P = 0.01). The presence of DSA and the administration of rituximab had strong impacts on not only short-term graft rejection, but also long-term graft rejection and its association with the graft survival time.

Abstract
OBJECTIVES To investigate the incidence of asymptomatic unruptured renal artery pseudoaneurysm detected by 3-D computed tomography arteriography in the early period after minimally invasive partial nephrectomy, including laparoscopic and robotic partial nephrectomy. METHODS From February 2012 to November 2013, 101 patients underwent minimally invasive partial nephrectomy for renal masses. Computed tomography arteriography was carried out 3-4 days after surgery; radiologists diagnosed renal artery pseudoaneurysm in a blinded manner. Factors influencing the occurrence of renal artery pseudoaneurysm were analyzed with the logistic regression model. RESULTS The incidence of renal artery pseudoaneurysm was unexpectedly high at 21.7% when detected by computed tomography arteriography during the early period after minimally invasive partial nephrectomy. The renal artery pseudoaneurysm group showed a significantly larger tumor size (P = 0.02), significantly higher N component score (P = 0.01) and higher incidence of renal sinus exposure or opening of the collecting system (P < 0.01) compared with the no renal artery pseudoaneurysm group. Although these aforementioned factors were found to be significant by univariate analysis, multivariate analysis showed that renal sinus exposure was the only significant independent predictive factor for occurrence of renal artery pseudoaneurysm. Tumor-related factors, such as the N component of the nephrometry scoring system or tumor size, did not show an independent influence on the occurrence of renal artery pseudoaneurysm. CONCLUSIONS The present study shows an unexpectedly high incidence of asymptomatic unruptured renal artery pseudoaneurysm detected by computed tomography arteriography in the early period after minimally invasive partial nephrectomy. Renal sinus exposure is an independent significant factor predicting the occurrence of renal artery pseudoaneurysm. Avoidance of deep excision into the renal sinus could reduce the risk of renal artery pseudoaneurysm.

Abstract
AIM Transplant glomerulopathy (TG) is included as one of the criteria of chronic active antibody-mediated rejection (c-AMR) in Banff 09 classification. In this report, we discuss the clinical and pathological analyses of cases of TG after renal transplantation. PATIENTS TG was diagnosed in 86 renal allograft biopsy specimens (BS) obtained from 50 renal transplant patients followed up at our institute between January 2006 and October 2012. We retrospectively reviewed the data of these 86 BS and 50 patients. RESULTS Among the 50 patients, 42 (84%) had a history of acute rejection (AR); of these, 30 (60%) had acute antibody-mediated rejection (a-AMR). Among the 86 BS of TG, the TG was mild in 35 cases (cg1 in Banff classification), moderate in 28 cases (cg2) and severe in 23 cases (cg3). Peritubular capillaritis was present in 74 BS (86%), transplant glomerulitis in 65 (76%), interstitial fibrosis and tubular atrophy (IF/TA) in 71 (83%), thickening of the peritubular capillary (PTC) basement membrane in 72 (84%), and interstitial inflammation in 40 (47%). C4d deposition in the PTC was present in 49 BS (57%); 39 of these 49 BS showed diffuse C4d deposits in the PTC (C4d3), while the remaining 10 BS showed focal deposits (C4d2). Diffuse C4d deposition in the glomerular capillaries (GC) was seen in 70 BS (81%), while focal C4d deposition in the GC was seen in 9 (11%). In the assay using plastic beads coated with HLA antigen performed in 67 serum samples obtained in the peri-biopsy period, circulating ant-HLA alloantibody was detected in 55 (82%); in 33 of the 55 (49%) samples, donor-specific antibodies (DSA) were detected. Among our study, the findings in 22 BS (26%) fully met the criteria for c-AMR in Banff '09 classification, including TG, C4d deposition in the PTC and presence of DSA, while those in 27 BS were suspicious of c-AMR. Deterioration of the renal allograft function after the biopsies was seen in 31 patients (62%), of which 11 lost their graft. CONCLUSIONS We suggest that histopathological changes of transplant glomerulopathy might be accompanied by inflammation of the microvasculature, such as transplant glomerulitis and peritubular capillaritis, thickening of the peritubular capillary basement membrane, and circulating anti-HLA antibodies. C4d deposition in the PTC is not always present in biopsy specimens of TG. We speculated that C4d deposition in the GC, rather than that in the PTC might be a more characteristic manifestation of TG. Many of the patients with TG had a history of AR. Anti-HLA antibody Class II, particularly when the antibody was DSA Class II, appeared to be associated with the development of TG. The prognosis of grafts exhibiting TG was not too good even under the currently used immunosuppressive protocol.

Abstract
Background: Sleep has been identified as having an influence on the success of weight-loss interventions; however, knowledge of the mechanisms and the extent to which sleep disturbances affect the magnitude of weight reduction is inconclusive. Objective: To determine if sleep duration and quality can predict the magnitude of weight reduction in a weight-loss intervention program for overweight and obese women. Methods: Ninety overweight and obese women aged 25–65 years completed the 7-month weight-loss phase of our weight-loss intervention. Sleep duration and quality were evaluated before the intervention by the Pittsburg Sleep Quality Index (PSQI), a self-report questionnaire, and by actigraphy. Serum levels of ghrelin, leptin, cortisol and insulin also were measured at baseline. Insulin resistance was measured by the homeostasis model assessment of insulin resistance (HOMA-IR). Results: The mean reduction rate of body mass index (BMI) after the intervention was 13.6%. Multiple linear regression revealed that the number of wake episodes (WEs) per night had a significant relationship with the reduction of BMI even after adjusting for other clinical variables (β=−0.341, P=0.001). The participants with five or more WEs per night (high-WE group) had a significantly lower reduction in BMI compared with those with fewer than five (normal-WE group), after adjusting for confounding variables. In contrast, the PSQI-assessed parameters, reflecting the subjective assessments of sleep quality and duration, failed to detect an association with the reduction in BMI. Baseline HOMA-IR was significantly higher in the high-WE group than in the normal-WE group after adjusting for confounding variables. Conclusions: Higher sleep fragmentation, as manifested by the increased number of WEs, predicts a lower magnitude of weight reduction in persons participating in weight-loss programs.

Abstract
Recipient CD4 T regulatory cells inhibit the acute T cell-mediated rejection of renal allografts in wild-type mice. The survival of single class II MHC-disparate H-2(bm12) renal allografts was tested in B6.CCR5(-/-) recipients, which have defects in T regulatory cell activities that constrain alloimmune responses. In contrast to wild-type C57BL/6 recipients, B6.CCR5(-/-) recipients rejected the bm12 renal allografts. However, donor-reactive CD8 T cells rather than CD4 T cells were the primary effector T cells mediating rejection. The CD8 T cells induced to bm12 allografts in CCR5-deficient recipients were reactive to peptides spanning the 3 aa difference in the I-A(bm12) versus I-A(b) β-chains presented by K(b) and D(b) class I MHC molecules. Allograft-primed CD8 T cells from CCR5-deficient allograft recipients were activated during culture either with proinflammatory cytokine-stimulated wild-type endothelial cells pulsed with the I-A(bm12) peptides or with proinflammatory cytokine-simulated bm12 endothelial cells, indicating their presentation of the I-A(bm12) β-chain peptide/class I MHC complexes. In addition to induction by bm12 renal allografts, the I-A(bm12) β-chain-reactive CD8 T cells were induced in CCR5-deficient, but not wild-type C57BL/6, mice by immunization with the peptides. These results reveal novel alloreactive CD8 T cell specificities in CCR5-deficient recipients of single class II MHC renal allografts that mediate rejection of the allografts.
