RESUMEN

OBJECTIVE: to verify the association between seminal quality and seminal transferrin (ST) level and fertility index in patients undergoing chronic hemodialysis (CH). MATERIAL AND METHODS: This is a cross-sectional study in a group of 60 men (case) undergoing CH for more than 6 months, and a group of 30 healthy men (control), aged 18-60 years, without clinical or laboratory signs of infection/inflammation. Spermiogram was performed, fertility index (FI) was calculated and ST and sex hormones (SH) levels were measured, including follicle-stimulating hormone, luteinizing hormone, total testosterone, and prolactin. RESULTS: All individuals were eugonadal. No differences for age (49.47 ± 5.56, 47.90 ± 6.2, p = 0.22) were observed between cases and controls, whereas there were significant differences between the individuals in the case and control groups with respect to the mean FI (p = 0.000), seminal parameters (SP) (p = 0.000), and ST levels (40.12 ± 08.25 vs 73.32 ± 06.8, p = 0.000). ST levels were correlated with FI (r = 0.787, p = 0.00) and SP (motility: r = 0.857, p = 0.000; vitality: r = 0.551, p = 0.000; density: r = 0.850, p = 0.000; normal morphology: r = 0.386, p = 0.000). Linear regression model showed relationship of ST levels with total sperm motility (R2 = 0.701; p = 0.000) and and FI (R2 = 0.569; p = 0.000). CONCLUSIONS: Our results suggest that seminal quality is associated with ST levels and FI and that it can be used the initial investigation of subfertility/infertility of patients undergoing chronic hemodialysis..

RESUMEN

INTRODUCTION: To find out the changes in seminal quality of hemodialysis chronic renal patients, we investigated the possible relationship between seminal parameter and seminal α1-acid glycoprotein levels in chronic hemodialysis patients. METHODS: Prospective study of prevalence realized in the Hemodialysis Sector of the University Hospital of the University of Brasília, between July 2016 and December 2016. Men aged 18-60 years grouped into case groups (n = 81) represented by chronic hemodialysis patients and control group (n = 20) of healthy men without clinical or laboratory signs of infection and eugonadic. We performed a spermogram, hormonal profile, and assessment of leukocytes and seminal α1-acid glycoprotein level in the semen. The most appropriate statistical test was applied to verify differences and correlations between the studied variables. RESULTS: The age in case and control is similar (49.47 ± 5.55 years vs 50.53 ± 4.24 years; p = 0.060). Mean level of α1-acid glycoprotein in human seminal plasma were not significantly different between case and control (48.52 ± 4.90 mg/L vs 46.33 ± 4.29 mg/L; p = 0.10) and between normosperm and oligosperm (47.76 ± 5.15 mg/L vs 49.48 ± 4.49 mg/L; p = 0.19). Mean level of α1-acid glycoprotein in human seminal plasma in the case group, which were classified into severe, moderate, mild, and normosperm, were similar to each other (p = 0.27) and did not correlate (p > 0.05) with the analyzed seminal parameters. All participants presented normal hormonal profile. CONCLUSION: Results of this study suggest that the seminal α1-acid glycoprotein levels do not help in the initial evaluation of patients with seminal parameter changes.

RESUMEN

OBJECTIVE: We aimed to investigate the possible relationship between seminal parameters and cystatin C seminal levels in an infertility evaluation of chronic hemodialysis patients. MATERIALS AND METHODS: This was a cross-sectional study, aged 18-60 years, in a group of 60 men undergoing hemodialysis (case) for more than 6 months, and a group of 15 healthy men (control) without clinical or laboratory signs of genitourinary tract infection. We performed a spermogram, hormonal profile, and assessment of leukocytes and cystatin levels in the semen. RESULTS: The ages in the case and control were similar (p = 0.060). The seminal cystatin was significantly different between the case group and control group (41.16 ± 26.59 vs. 79.00 ± 05.68 mg/l, respectively, p < 0.001) and between normospermia and oligospermia (83.50 ± 02.40 vs. 30.34 ± 02.52 mg/l, respectively, p < 0.001). The mean seminal cystatin levels identified by the degrees of oligospermia (severe, moderate, and slim) were similar to each other (p > 0.05) and significantly different (p < 0.05) in relation to normospermia in the case group. The seminal cystatin levels positively correlated (p < 0.05) with sperm motility and sperm density. CONCLUSION: Seminal cystatin levels are associated with the numerical and motility changes evidenced in the spermogram and may be of help in the initial evaluation of clinical suspicion of sub-fertility and infertility.

RESUMEN

BACKGROUND: We proposed to investigate the possible relationship between seminal quality and ferritin and transferrin seminal levels in chronic hemodialysis (CH) patients. MATERIALS AND METHODS: This is a cross-sectional study in a group of 60 men (case) undergoing CH for more than 6 months, and a group of 30 healthy men (control), aged 18-60 years, without clinical or laboratory signs of infection/inflammation and eugonadic. A spermogram was performed by manual method and measured the ferritn and transferrin seminal levels. RESULTS: The case and control groups were age-matched (49.47±5.56 versus 47.90±6.22, p = 0.229). Comparison between case and control group, the exception of seminal ferritin levels that were similar (p = 0.136), were significantly lower in the case group (p<0.001) for all constituents of the seminal parameter and seminal transferrin levels. Seminal ferritin does not appear to be associated with seminal parameters and seminal transferrin (p>0.05); but there was an association between seminal transferrin and seminal parameters (p<0.001). CONCLUSIONS: Our results suggest that seminal quality is related to seminal transferrin level and not with seminal ferritin level being useful in the initial evaluation of chronic hemodialysis patients with clinical suspicion of sub / infertility.
