[Inluence of osteoporosis and its causative factors on the prevention of recurrence of urinary stone disease].

INTRODUCTION: The aim of postoperative examination, treatment and follow-up of patients with urinary stone disease is a prevention of recurrence. A choice of method of prevention is based on the results of postoperative examination with consideration of etiological factors of urinary stone disease. An analysis of influence of osteoporosis and its causative factors on the recurrence of urinary stone disease is presented in the article. AIM: to clarify the influence of osteoporosis and its causative factors on excretion of calcium, uric acid and recurrence of urinary stone disease. MATERIALS AND METHODS: A total of 86 patients after surgical treatment of urinary stone disease were included in the study. A physicochemical analysis of stones and their fragments, excretion of calcium and uric acid were done postoperatively. The risk factors for osteoporosis were identified using specific questionnaire. Bone mineral density (BMD) was assessed by X-ray densitometry. After X-ray phasic analysis of the stones and studying of the daily excretion of calcium and uric acid, 10 and 7 patients were prescribed to thiazide diuretics and allopurinol, respectively. In 69 patients (80.2%) there were no indications to the treatment and all of them were included in control surveillance group. RESULTS: Calcium oxalate stones were predominated in patients who were under surveillance (=0,0254). A prevalence of risk factors for osteoporosis was similar in all groups (=0,2156), as well as rate of decrease in BMD (=0,64). In patients taking thiazide diuretics, a significant decrease in daily calcium excretion was found (=0,0054) without significant changes in excretion of uric acid and diuresis volume. Among patients receiving allopurinol there was a significant decrease in daily uric acid excretion (=0,021), without significant changes in excretion of calcium and diuresis volume. There were no significant changes of these values in the control group. A recurrence of urinary stone disease in treatment group was detected in 4 patients with a decrease of BMD after 381+/-61 days, while in control group there were 5 recurrences in patients with decreased BMD and I recurrence in patient with normal BMD after 836+/-64 days. CONCLUSION: Treatment aimed at prevention of recurrence of urinary stone disease allows to correct detected metabolic disturbances. However, such factor as the decrease in BMD can influence on the rate and frequency of recurrence of urinary stone disease. A clarifying of risk factors for osteoporosis and diagnosis of osteoporosis allow to give reliable recommendations for its treatment and to decrease risk of recurrence of urinary stone disease.

[Characteristic features of urinary calcium excretion and osteoporosis risk factors in patients with urolithiasis].

RELEVANCE: The prevalence of urolithiasis and osteoporosis (OP) indicates that these diseases may be found concurrently in the same patient. The detection of risk factors for OP and disorders of calcium metabolism in patients with urolithiasis is of interest in the context of primary stone formation and metaphylaxis. AIM: To identify risk factors for osteoporosis and disorders of calcium metabolism in patients with urolithiasis. MATERIALS AND METHODS: Osteoporosis risk factors were studied in 45 urolithiasis patients undergoing surgical treatment. Patients were asked to fill out the osteoporosis risk factor questionnaire, and urinary calcium excretion was measured in 24-h collections. RESULTS: Risk factors for osteoporosis were detected in 20 (44.4%) urolithiasis patients. Patients with osteoporosis risk factors identified by the questionnaire were statistically significantly older (p=0.032). Osteoporosis risk factors were found in 20% of patients with newly diagnosed urolithiasis and 24.4% of patients with recurrent urolithiasis. The study patients showed increased urinary calcium excretion and decreased diuresis. The negative correlation between urinary calcium excretion and 24-h diuresis was greater in patients who had than in those who did not have osteoporosis. CONCLUSION: An increase in urinary calcium excretion and a decrease in diuresis can be a predisposing factor for the recurrence of urolithiasis. In patients with risk factors for osteoporosis, it can provide a rationale for administering drugs aimed at preventing stone formation (thiazide diuretics).

Prevalence and Prognostic Value of Depression and Anxiety in Patients with Diabetic Foot Ulcers and Possibilities of their Treatment.

BACKGROUND: Depression and anxiety can potentially influence treatment results of diabetic complications. OBJECTIVE: Of our study was to explore: (1) prevalence of these disorders in patients with diabetic foot ulcers (DFU); (2) possible risk factors of depression and anxiety; (3) possible links between ulcer treatment results and depression/anxiety status. METHODS: 285 outpatients with diabetes and foot or leg ulcers were tested for depression and anxiety with self-report scales: CES-D and the anxiety subscale from HADS. Ulcer treatment results, incidence of new ulcers and number of hospital admissions were assessed after 1.5 years of follow-up. RESULTS: Depression was detected in 110 patients (39%), anxiety in 103 (36%). Females had depression and anxiety more often than males (48% and 46% vs. 27% and 25% respectively). A combined score based on diabetes duration, insulin treatment, history of myocardial infarction, history of foot ulcers and recent foot surgery was higher in patients with than without depression (3.0 vs. 2.0, p=0.02). Every of these or other potential risk factors alone was not associated with depression or anxiety. Patients with depression did not demonstrate poorer prognosis except higher mortality in subgroup of severely depressed patients without ulcer history. For anxiety we got similar results as its presence strongly correlated with depression. CONCLUSION: The overall prevalence of depression and anxiety in DFU patients is compatible with other diabetic populations. Various parameters of ulcer severity and duration did not influence the probability of depression and anxiety occurrence. Depression in general was not associated with poorer ulcer treatment results.
