Association of calcium antagonist use with lower hemoglobin levels in hemodialysis patients.

AIM: Objective of the present study was to investigate whether calcium antagonist use is associated with lower hemoglobin levels and/or higher erythropoiesis stimulating agent (ESA) requirement in hemodialysis patients. METHODS: A total of 130 adult hemodialysis patients were classified into two groups based on calcium antagonist usage for a period of at least 3 months as calcium antagonist users and calcium antagonist non-users. The two groups were compared cross-sectionally in a retrospective manner in terms of demographics, chronic kidney disease aetiologies, Charlson's Comorbidty Index, blood pressure, type of dialysis access, interdialytic body weight gain, cardiothoracic index, complete blood count, biochemistry, regular medication use and consumption of ESA. All independent variables that were different between the groups were subjected to logistic regression analysis. Linear regression analysis with dependent variable of hemoglobin value was also performed RESULTS: ESA consumption and blood pressure were higher, diabetic nephropathy, doxazosin and ACE inhibitor use were more frequent, and hemoglobin was lower in the calcium antagonist users. After logistic regression analysis, diabetic nephropathy, doxazosin use, ACE inhibitor use and lower hemoglobin were associated with calcium antagonist use. After lineer regression analysis, Age, BMI, gender, predialysis creatinine value, dialysis duration, systolic and diastolic blood pressure, doxazosin use, diabetes mellitus and diabetic nephropathy were not related with hemoglobin value. But, higher amount of ESA consumption, ACE inhibitor use and calcium antagonist use were significantly associated with lower hemoglobin value. CONCLUSION: CA use was associated with lower hemoglobin levels in our hemodialysis patient population.

Association of calcium channel blocker use with lower hemoglobin levels in chronic kidney disease.

AIM: To search whether calcium channel blockers (CCBs) are associated with lower hemoglobin levels in chronic kidney disease (CKD) patients who are not on renal replacement therapy (RRT), vitamin D and anti-anemic treatment. PATIENTS AND METHODS: CKD patients were classified into two groups. Patients on CCBs treatment (103 patients) and patients not using CCBs (104 patients) were compared cross-sectionally regarding clinical findings, complete blood count (CBC), biochemistry and regular medication use. Patients with polycystic kidney disease, comorbidities that could influence CBC other than iron deficiency of obscure origin, patients receiving RRT, erythropoietin (EPO), vitamin D, phosphate binders and drugs that could influence CBC were excluded. Under dependent variable of CCB use, all significantly different independent variables were subjected to multivariate binary logistic regression analysis (MBLRA). RESULTS: Lower hemoglobin, lower bilirubinemia, higher serum EPO, higher systolic blood pressure were observed in CCB users. Two groups were similar concerning age, gender, BMI, CKD etiology, CKD stage, pretibial edema prevalence, cardiothoracic index, diastolic blood pressure, corrected reticulocyte count, BUN, creatinine, eGFR, proBNP, parathormone, alkaline phosphatase, phosphorous, corrected calcemia, sCRP, relative EPO deficiency and prevalence of relative EPO deficient patients. Groups were comparable regarding comorbidities, types and usage frequencies of all antihypertensive medications other than CCBs. Higher systolic blood pressure and lower hemoglobin were significantly associated with CCB use after MBLRA. CONCLUSIONS: Hemoglobin was significantly lower in CCB users compared to non-users, among CKD patients who did not receive RRT, EPO, phosphate binders, vitamin D, iron, vitamin B12 and folic acid.

Patients' experiences at home after day case cystoscopy.

AIM: To determine patients' problems with day case cystoscopy and their problem solving ways and patients' self-care at home. BACKGROUND: Day surgery has become increasingly common in the last 20 years. Cystoscopic procedures are increasingly being carried out as a diagnostic and therapeutic procedures. DESIGN AND METHOD: This descriptive/prospective study comprised 50 patients undergoing day case cystoscopic procedures in the university hospital of Turkey. The data were collected using telephone interview three days after the procedure. The two questionnaire used were Symptom Measurement Questionnaire and Symptom Management Questionnaire. Discharge information and written instruction was given to all patients. RESULTS: It was found in the investigation that the most common problems experienced by the patients were tiredness, haematuria, dysuria, pain over bladder and difficulty in voiding after flexible cystoscopy in first day. Generally, urinary elimination problems were experienced by majority of the patients. At second day, these problems were also common. The mean score for all problems decreased after three days. The patients stated that they were able to deal with their symptoms either independently or to a lesser extent with assistance of a carer. But they were unable to deal with problems such as especially haematuria. CONCLUSION: Problems experiences by the patients at home after cystoscopy influenced some daily living activities. The problems related to voiding are more frequently observed after cystoscopy. Although some these problems are related to the procedures, some were present previously. RELEVANCE TO CLINICAL PRACTICE: This findings indicate that patient-centred care should be strengthened at home in urological day surgery.
