Sexual dysfunction in women with ESRD requiring hemodialysis.

BACKGROUND AND OBJECTIVES: The few existing studies of sexual dysfunction in women on hemodialysis are limited by small sample size. This large, cross-sectional study evaluated the prevalence and correlates of female sexual dysfunction in advanced kidney disease. DESIGN, SETTING, PARTICIPANTS, METHODS: A total of 1472 women with ESRD undergoing hemodialysis were recruited to a multinational, cross-sectional study conducted within a collaborative dialysis network in Europe and South America. Sexual dysfunction was identified by the Female Sexual Function Index. Correlates of self-reported sexual dysfunction were identified by regression analyses. RESULTS: Of the 1472 women, 659 completed questionnaires (45%). More than half (362 of 659 [55%]) lived with a partner, and 232 of 659 (35%) reported being sexually active. Of these 659 respondents, 555 (84%) reported sexual dysfunction. Women with a partner (282 of 362 [78%]) were less likely to report sexual dysfunction than those without a partner (273 of 297 [92%]) (P<0.001). Sexual dysfunction was independently associated with age, depressive symptoms, less education, menopause, diabetes, and diuretic therapy. Nearly all women who were not wait-listed for a kidney transplant and were living without a partner (249 of 260 [96%]) reported sexual dysfunction. More than half (128 of 232 [55%]) of sexually active women reported sexual dysfunction, associated with age, depressive symptoms, menopause, low serum albumin, and diuretic therapy. CONCLUSIONS: This descriptive study suggests most women on hemodialysis experience sexual problems. Additional research on the relevance of sexual dysfunction to symptom burden and quality of life in these women is needed.

Prevalence and correlates of erectile dysfunction in men on chronic haemodialysis: a multinational cross-sectional study.

BACKGROUND: Factors associated with erectile dysfunction in men on haemodialysis are incompletely identified due to suboptimal existing studies. We determined the prevalence and correlates of erectile dysfunction and identified combinations of clinical characteristics associated with a higher risk of erectile dysfunction using recursive partitioning and amalgamation (REPCAM) analysis. METHODS: We conducted a multinational cross-sectional study in men on haemodialysis within a collaborative network. Erectile dysfunction and depressive symptoms were evaluated using the erectile function domain of the International Index of Erectile Function questionnaire and the Center for Epidemiological Studies-Depression Scale, respectively. RESULTS: Nine hundred and forty-six (59%) of 1611 eligible men provided complete data for erectile dysfunction. Eighty-three per cent reported erectile dysfunction and 47% reported severe erectile dysfunction. Four per cent of those with erectile dysfunction were receiving pharmacological treatment. Depressive symptoms were the strongest correlate of erectile dysfunction [adjusted odds ratio 2.41 (95% confidence interval (CI) 1.57-3.71)]. Erectile dysfunction was also associated with age (1.06, 1.05-1.08), being unemployed (1.80, 1.17-2.79) or receiving a pension (2.05, 1.14-3.69) and interdialytic weight gain (1.9-2.87 kg, 1.92 [CI 1.19-3.09]; >2.87 kg, 1.57 [CI 1.00-2.45]). Married men had a lower risk of erectile dysfunction (0.49, 0.31-0.76). The prevalence of erectile dysfunction was highest (94%) in unmarried and unemployed or retired men who have depressive symptoms. CONCLUSIONS: Most men on haemodialysis experience erectile dysfunction and are untreated. Given the prevalence of this condition and the relative lack of efficacy data for pharmacological agents, we suggest that large trials of pharmacological and non-pharmacological interventions for erectile dysfunction and depression are needed.

Is time on cardiopulmonary bypass during cardiac surgery associated with acute kidney injury requiring dialysis?

It is commonly accepted that the longer the time on extracorporeal cardiopulmonary bypass (CPB), the higher is the likelihood of developing acute renal failure requiring dialysis (ARF-D). Nonetheless, previous works elicited conflicting evidence. We investigated the relationship between CPB duration and ARF-D occurrence. Data were extracted from a large observational study. All factors independently associated with ARF-D were detected. Overall, 11,092 case record forms were analyzed. At the univariate analyses, time on CBP was associated with an increase in the ARF-D risk (odds ratio of fifth vs. first quintile of CBP time: 3.84; 95% confidence interval: 2.58-5.7; P < 0.001). However, after adjusting for confounders, the association between time on CBP and ARF-D lost its statistical significance. In this large dataset, CBP time did not predict ARF-D occurrence. These results might suggest that an accurate risk assessment might be more important than time on CPB in determining ARF-D occurrence.
