Predictive Value of Interleukin 2 and Interleukin 8 on Early Rejection in Living Related Kidney Transplant Recipients.

INTRODUCTION: Early diagnosis of rejection in kidney transplant (KTx) recipients is of paramount importance for long-term graft survival. Cytokines play an important role in rejection via activating T cells. Neutrophil accumulation in the graft indicates cell-mediated rejection. Cellular infiltration is mediated through chemoattractant factors. The aim of this study was to investigate the relationship between graft function and serum levels of interleukin 2 (IL-2) and interleukin 8 (IL-8) in KTx. METHOD: Sixty-five patients undergoing KTx were enrolled in the study. Serum samples of IL-2 and IL-8 were collected the day before the operation, on postoperative days 1 and 7 day, and during the first and third month after the onset of rejection. The enzyme-linked immunosorbent assay method was used to determine the IL-2 and IL-8 values. RESULTS: A total of 9 (13.8%) patients had rejection documented on biopsy samples. Fifty-six patients had stable graft function (SGF). IL-2 and IL-8 values before KTx of both the rejected and SGF patients were not statistically different. Univariate analysis revealed that IL-2 and IL-8 were correlated with rejection (P = .046, P = .015). IL-8 levels were higher in the rejection group compared to the SGF group on the seventh day and first month postoperatively (P = .023, P = .038). The rejection group maintained higher levels of IL-8 for 11 days (range: 7-30) compared to the SGF group (P = .002) and the IL-8 levels correlated with serum creatinine levels (r = 0.621, P = .001). IL-2 levels were higher in the rejection group on days 1 and 7 compared to the SGF group (P = .042, P = .031). IL-2 and IL-8 levels were correlated with low eGFR in the third month in the rejection group (r = 0.421, P = .037; r = 0.518, P = .008). CONCLUSION: Determining the cytokine levels in the early post-KTx period may be helpful in tailoring immunosuppressive regimens in patients with a risk of rejection.

Effect of Donor Nephrectomy Technique on Recipient Lymphatic Drainage.

AIM: We sought to evaluate the postoperative recipient lymphatic drainage depending on open donor nephrectomy (ODN) or laparoscopic (LDN) techniques. METHOD: Between March 2012 and August 2014, 58 patients underwent renal transplantation from living-related donors. Thirty donors underwent ODN (group 1), and 28 LDN (group 2). Operations were performed by the same surgeons. Both cranial and caudal drainage catheters for lymphatic leakage were placed preoperatively and all the recipients received tacrolimus, mycophenolate mofetil, and steroid as immunosuppressive regimen. None of the patients had coagulation abnormalities. RESULTS: All grafts were functioning during the early postoperative period and diuresis was ensured. No difference was observed on early postoperative period regarding to acute rejection (P = .329) or infection (P = .546). No difference was seen concerning mycophenolate mofetil and mycophenolate sodium regimens among the 2 groups (P = .227). In groups 1 and 2, the cranial drainage catheters were not taken out until postoperative days 5.5 ± 2.5 (range, 0-11) and 6.4 ± 3.8 (range, 0-14) and the caudal catheters stayed in place until days 8.8 ± 3.5 (range, 1-16) and 9.9 ± 5.9 (range, 3-22), respectively. No difference was found when comparing the cranial (P = .308) and caudal (P = .426) drainage periods. However, during clinical acute rejection episodes the cranial drainage period was longer in group 1 (P = .003). Three patients developed lymphoceles, 1 requiring drainage, in group 2. CONCLUSIONS: There seems to be no difference in recipient lymphatic drainage by donor nephrectomy technique. A laparoscopic procedure may be advantageous owing to shorter lymphatic drainage during clinical acute rejection episodes.

Does sexual dysfunction correlate with deterioration of somatic sensory system in diabetic women?

To evaluate genital and extragenital somatic sensory system in diabetic women using biothesiometry and investigate the relation with sexual dysfunction. A total of 30 diabetic women and 20 normal sexually active women as a control group were evaluated with a detailed medical and sexual history including Index of Female Sexual Function (IFSF) questionnaire. Somatic sensory system of all women enrolled to the study was assessed by biothesiometry and threshold sensory values of nine genital sites and 14 extragenital sites were analyzed. The IFSF score in diabetic women was 23.6 while it was 38.3 in the control group (&<0.0005). For each genital as well as extragenital sites, the mean biothesiometric values were significantly higher in diabetics. The sensation of introitus vagina, labium minora and clitoris were found to be the most deteriorated genital sites in diabetic women. The difference between diabetic women with or without female sexual dysfunction (FSD) was not significant for biothesiometric values. Our data indicate that, somatic sensory system is affected by diabetes however sexual dysfunction does not always manifest.

Primary gonadotropin releasing hormone and adjunctive human chorionic gonadotropin treatment in cryptorchidism: a clinical trial.

OBJECTIVES: The effect of intranasal gonadotropin-releasing hormone (GnRH) and intramuscular human chorionic gonadotropin (hCG) in the treatment of cryptorchidism was investigated in 48 prepubertal boys. METHODS: Forty-eight prepubertal boys with 70 undescended testes were enrolled into a prospective study between November 1989 and November 1991. GnRH was applied as nasal spray at a dose of 1.2 mg/day for 4 weeks. The patients with partial descent were subsequently treated with 1500 IU hCG weekly for 3 weeks. RESULTS: Complete descent was observed in 53% (37 of 70) of testes; 58% (15 of 26) in unilateral and 50% (22 of 44) in bilateral undescended testes. One abdominally located testicle did not respond to therapy. Of 37 testes located in the inguinal canal, seven (19%) descended. On the other hand, descensus rates were 100% for the testes located at the external inguinal ring and at a high scrotal level. Six primarily descended testes (16%) showed relapse during the follow-up. Surgery was performed in 12 patients (14 testes), revealing associated hernia in nine testes and epididymal anomalies in four. CONCLUSIONS: We believe that the GnRH and hCG combination is an effective therapy for undescended testes located at and beyond the external inguinal ring and should be the first treatment choice because of its noninvasiveness. Both unilateral and bilateral undescended testes responded with similar success rate to hormonal therapy. Surgery should be considered for proximal cryptorchidism.

A case of ureteral triplication (type 1) associated with vesicoureteral reflux in a solitary kidney.

Ureteral triplication is a rare congenital anomaly of the upper urinary tract. It is reported to be associated with an increased incidence of congenital anomalies as well as a predisposition to infection and calculus formation. We report a case of type 1 variant of ureteral triplication associated with vesicoureteral reflux into lower and mid pole ureters in a solitary kidney. To our knowledge ureteral triplication in a solitary kidney has not been described previously.

The management of renal candidiasis in the newborn.

Renal candidiasis in the neonate is encountered infrequently. We report a newborn with ichthyosis, who during the hospital course had five episodes of culture-proven sepsis, probably due to skin lesions. For these infections various antibiotic combinations were used. During the therapy of the last sepsis attack, unilateral hydronephrosis developed secondary to renal candidiasis. Percutaneous nephrostomy with amphotericin B irrigation, coupled with five weeks of intravenous amphotericin B therapy was successful. We believe that with this approach the mortality and morbidity of renal candidiasis could be reduced.

Primary signet ring cell carcinoma of the urinary bladder. Review of the literature and report of two cases.

The signet ring cell carcinoma of the urinary bladder is a rare neoplasm; the 70 cases found in the literature pursued a fulminant and mostly fatal course; the neoplasms diffusely invaded the bladder wall without forming intraluminal growths and could not be controlled by segmental resection, radiotherapy and chemotherapy alone or in combination. We herewith present 2 cases of primary signet ring cell carcinoma of the urinary bladder--one associated with high-grade transitional cell carcinoma and in situ carcinoma--and review the literature.

Cryptorchidism: is orchidopexy always preventive treatment for infertility?

Cryptorchidism is one of the testicular factors recognized as preventable disease processes. Although the effect of bilateral cryptorchidism on fertility is well documented, more studies are required in order to determine the bilateral functional and histologic effects of unilateral cryptorchidism. This clinical retrospective study analyses the effects of cryptorchidism on fertility and histopathologic changes in dystopic and eutopic testes. Among 1400 patients consulted in our infertility clinic between the years of 1989 and 1993, 47 patients (3.3%) had cryptorchidism (29 unilateral/18 bilateral). Among these patients 26 had a history of orchidopexy (mean age at the time of operation: 13.11 +/- 5.24 years). Semen analyses (3x) were available in 43 and hormone profile in 27 out of 47. The incidence of abnormal semen parameters in unilateral and bilateral group was 89.6% and 100%, respectively. Testicular biopsies were obtained from 17 patients (10 with unilateral and 7 with bilateral disease). The biopsy findings in 75% of eutopic testes in unilateral group were similar to that of dystopic testis. The high incidence and significant histologic changes in eutopic testis supports the hypothesis that the disease might be bilateral in nature. The question whether the progression of the disease can be stopped by early orchidopexy still remains unanswered until long term follow-up studies are completed.
