Background and Objectives: chronic kidney disease (CKD) is now a global public health problem. In low- and middle-income countries such as the Congo, access to dialysis is low and inequitable. The prevention of CKD involves raising awareness among patients at risk, such as those suffering from arterial hypertension (AH), by improving their knowledge of CKD. The objectives of our work were to determine the level of knowledge about CKD among hypertensive patients and to identify the factors associated with a low level of knowledge. Methodology: We conducted a 3-month descriptive and analytical cross-sectional study from 1 August to 30 October 2023 in 3 large public hospitals in Brazzaville (capital of the Republic of Congo). We included: hypertensive patients aged 18 and over who had freely consented to participate in our study and were able to answer the questions on the survey form. Patients with known hypertension who had been followed for less than 3 years and those with known chronic renal failure were not included. Results: The mean age was 58.4 ± 14.4 years (29 - 88 years). There were 121 men and 150 women (sex ratio = 0.8). All the patients were educated;37.2% with a higher level of education and 13.6% with primary education. 24 patients (9%) had a good level of knowledge about CKD and 153 (56%) had poor knowledge. A good level of knowledge was associated with the duration of hypertension, intellectual level and the existence of associated heart disease. Conclusion: Our study reveals a significant lack of knowledge about chronic kidney disease among hypertensive patients in Brazzaville.

chronic administration of sildenafil improves erectile function in a rat model of chronic renal failure

引用

Asian Journal of Andrology 2015年第5期17卷 797-801,I0008-I0009页

作者： Nilgun Gurbuz Arif Kol Tumay Ipekci Erhan Ates Asli Baykal Mustafa F Usta Department of Biochemistry Akdeniz University School of Medicine Antalya Turkey Department of Urology Section of Andrology Akdeniz University School of Medicine Antalya Turkey

The relationship between erectile dysfunction （ED） and chronic renal failure （CRF） has been reported in several studies. This study aimed to investigate whether the chronic use of sildenafil could enhance the erectile capacity in CRF-induced rats. In addition, we assessed the effect of that treatment on certain molecules, which have been suggested to play crucial roles in erectile physiology and CRF-related ED as well. Three groups of animals were utilized：（1） age-matched control rats, （2） CRF-induced rats, （3） CRF-induced rats treated with chronic administration of sildenafil （5 mg kg^-1 p.o. for 6 weeks [treatment started after 6 weeks of CRF induction]）. At 3 months, all animals underwent cavernosal nerve stimulation （CNS） to assess erectile function. Penile tissue advanced glycation end products （AGE＇s）/5-hydroxymethyl-2-furaldehyde, malondialdehyde （MDA）, cGMP （ELISA）, inducible nitric oxide synthase （iNOS） and neuronal NOS （nNOS）（Western blot） analyses were performed in all rat groups. CRF-induced rats had a significant decrease in erectile function when compared to control rats （P 〈 0.05）. The increase in both intracavernosal pressure （ICP） and area under the curve of CRF-induced rats treated with sildenafil （Group 3） was greater than CRF-induced rats （Group 2）. Additionally, sildenafil treatment decreased AGE, MDA and iNOS levels, while it preserved nNOS and cGMP contents in CRF-induced penile tissue. Decreased AGE, MDA, iNOS and increased nNOS, cGMP levels at the sildenafil-treated group increased both ICP and Total ICP to CNS, which led to improve erectile function in CRF-induced rats. The results of the present study revealed the therapeutic effect of chronic sildenafil administration on erectile function in CRF-induced rats.

Effects of chronic renal failure on the expression of connexin 43 in the rat＇s corpus cavernosum

引用

Asian Journal of Andrology 2008年第2期10卷 286-289页

作者： Qiang Fu Jia-Jv Lv Hui Zhang Department of Urology Shandong Provincial Hospital Shandong University Jinan 250021 China

Aim： To explore the mechanism of chronic renal failure （CRF）-related erectile dysfunction （ED）. Methods： CRF experimental models were established by 5/6 nephrectomy from male Sprague-Dawley rats. Both the rats from the control group （NCRF group, n = 6） and the experimental group （CRF group, n = 30） were injected with a low dose （80 μg/g） of apomorphine in the 12th week after resection surgery to measure corresponding penile erections. Western blot method was thereafter conducted to measure the expression of connexin 43 （CX43） in the rat corpus cavernosum in the 12th week after the resection surgery. Results： There was one death in the NCRF group and five in the CRF group. The penile erection ratio of the CRF group was 28% （7/25）, whereas that of the NCRF group was 100% （5/5）, which presents a significant difference between the two groups （P 〈 0.05）. In terms of penile erection frequency, the average of the CRF group was 1.0 ± 0.0, which was significantly different from that of the NCRF group （2.2 ± 0.8）（P 〈 0.05）. As for the expression of CX43 in the rat corpus cavernosum, a notable difference existed between the CRF group （0.21 ± 0.07） and the NCRF group （0.53 ± 0.27）（P 〈 0.01）. Conclusion： CRF significantly reduces the erectile function of rats. A close correlation exists between the expression of CX43 in rats＇ corpus cavernosum and CRF-related ED. （Asian J Andro12008 Mar; 10： 286-289）

AIM： To investigate the role of wireless capsule endoscopy （WCE） in detection of small bowel （SB） pathology in patients with chronic renal failure （CRF） and obscure bleeding. METHODS： Consecutive CRF patients with obscure bleeding were prospectively studied. Patients with normal renal function and obscure bleeding, investigated during the same period with WCE, were used for the interpretation of results. RESULTS： Seventeen CRF patients （11 overt, 6 occult bleeding） and 51 patients （33 overt, 18 occult bleeding） with normal renal function were enrolled in this study. Positive SB findings were detected in 70.6% of CRF patients and in 41.2% of non-CRF patients （P〈0.05）. SB angiodysplasia was identified in 47% of CRF patients and in 17.6% of non-CRF patients. Univariate logistic regression revealed CRF as a significant predictive factor for angiodysplasia （P〈0.05）. Therapeutic measures were undertaken in 66% of the patients with the positive findings. CONCLUSION： According to our preliminary results, SB angiodysplasia was found in an increased prevalence among CRF patients with obscure bleeding. WCE is useful in diagnosis of gastrointestinal pathologies and in planning appropriate therapeutic intervention and, therefore, should be included in the work-up of this group of patients.

Effects of Helicobacter pylori infection on gastric epithelial cell kinetics in patients with chronic renal failure

AIM： To evaluate the effects of Helicobacter pylori infection on gastric epithelial cell kinetics in patients with chronic renal failure （CRF）. METHODS： Forty-four patients were enrolled in this study and divided into four groups with respect to their Helicobacter pylori （H pylori） and CRF status. Groups were labeled as follows： la： normal renal function, H pylori negative （n = 12）, lb： normal renal function, H pylori positive （n = 11）, 2a： CRF, H pylori negative （n = 10）, 2b： CRF, H pylori positive （n = 11）. Upper gastrointestinal endoscopy was done in all the patients involved in the study. During endoscopical investigation, antral biopsy specimens were taken from each patient. In order to evaluate the cell apoptosis and proliferation in gastric epithelial cells, Bax and proliferating cell nuclear antigen （PCNA） labeling indexes （LI） were assessed with immunohistochemical staining method. RESULTS： For groups la, lb, 2a, and 2b, mean Bax LI was identified as 34.4±13.7, 44.1±16.5, 46.3±20.5, 60.7±13.8, respectively and mean PCNA LI was identified as 36.2±17.2, 53.6±25.6, 59.5±25.6, 67.2±22, respectively. When the one-way ANOVA test was applied, statistically significant differences were detected between the groups for both Bax LI （P = 0.004 〈0.01） and PCNA LI （P = 0.009 〈0.01）. When groups were compared further in terms of Bax LI and PCNA LI with Tukey＇s HSD test for multiple pairwise comparisons, statistically significant difference was observed only between groups la and 2b （P = 0.006 〈0.01）.CONCLUSION： In gastric epithelial cells, expression of both the pre-apoptotic protein Bax and the proliferation marker PCNA increase with H pylori infection. This increase is more evident in patients with uremia. These findings suggest that uremia accelerates apoptosis and proliferation in gastric epithelial cells.
