Elements of renal injury in patients with varicose ulcer. Preliminary study.

The kidney may be affected in the processes of microbial, viral, parasitic infections. Knowledge of renal disease during chronic infection, with a different location than the throat, is of particular importance for the practicing physician for the detection and prevention of impaired renal function. Chronic kidney disease recovered in the early stages can prevent the progression of renal function decline. We studied a total of 85 patients with varicose ulcers with a mean age of 66.78 +/- 12.09 years, hospitalized in the Clinic of Dermatology and a control group consisting of 110 apparently healthy individuals. Urinary abnormalities have been detected in 26 (30%) of patients studied. GFR < 60 ml/min have been detected in 14 (17%) of patients studied. CRF stage II have been detected in 36 (42%) of patients studied. We detected recurrent varicose ulcer in 2 (2%) of patients studied. In two (2%) of patients during hospitalization we found a decrease in GFR by 15 and 12 ml/min, accompanied by an increase in serum creatinine from 0.7 mg % to 1 mg % in one patient and in another patient from 1.5 mg % to 2 mg %. Urinary abnormalities detected in patients with both acute and recurrent erysipelas warn about renal impairment and the need for monitoring of the renal patients with varicose ulcers.

Elements of renal injury in patients with erysipelas.

Erysipelas is an infectious disease caused by group A beta hemolytical streptococci which may produce renal lesions, most frequently glomerular disease. Renal injury although known is less studied in practice. Rarely bioptical exams have been performed, thus the problem of the relationship erysipelas glomerular disease is practically not solved. The aim of this study was a cross-sectional analysis of renal involvement produced by erysipelas in two departments where patients with erysipelas are diagnosed and treated: Dermatology and Infectious Diseases. We investigated 166 patients (86M, 80F; mean age 61.66 +/- 18.42) with erysipelas hospitalized in the Departments of Dermatology (55 patients-33%) and Infectious Diseases (111 patients-66%) during 2005-2009. The diagnosis was established on clinical and biological data. In these patients clinical and biological exam has been performed. We assessed GFR and urinalysis (hematuria and proteinuria). The control group consisted of 110 apparently healthy persons. Of the 166 patients with erysipelas we found asymptomatic urinary abnormalities in 82 (47%), isolated proteinuria in 19 (11%) patients and proteinuria associated with hematuria in 21 (13%) patients, and isolated hematuria in 38 (23%) patients. We did not find patients with nephrotic or nephritic syndrome. In the control group we found asymptomatic urinary abnormalities in 25 (23%) of the patients. A statistically significant difference was between the two groups (p < 0.01). Asymptomatic urinary abnormalities have been more frequent in patients with erysipelas from the Infectious Diseases Department compared to those from the Dermatology Department. A statistically significant difference has been found (p < 0.03). In patients with recurrent erysipelas (43 patients-26%) we found asymptomatic urinary abnormalities in 26 (54%) of the patients compared to the presence of asymptomatic urinary abnormalities in patients with acute erysipelas in 56 out of 123 (46%). Mean GFR in patients with erysipelas was of 73.94 +/- 27.79 ml/min. It was lower in patients with recurrent erysipelas, 72.13 +/- 24.74 mL/min respectively. Association of proteinuria with hematuria was more frequent in patients with recurrent erysipelas. Patients with asymptomatic urinary abnormalities during the course of erysipelas need to be closely monitored during antibiotic treatment.
