Rationale: Ozone autohemotherapy as an alternative treatment method has been applied to the treatment of several diseases. Here, we report a patient used ozone autohemotherapy to treat her hypertension and diabetes. Nevertheless, the patient occurred sudden dizziness and black haze due to hyperkalemia., Patient Concerns: A 54-year-old woman who was admitted to our emergency department complaining of sudden dizziness and black haze for 5 hours., Diagnoses: The blood potassium test showed hyperkalemia. Upon further inquiry of her medical history, the patient received ozone autohemotherapy to treat hypertension and diabetes for 9 days prior to admission., Interventions: The ozone therapy had been asked to stop. Insulin, sodium bicarbonate, and sodium polystyrene sulfonate were administered to the patient., Outcomes: After treatment, blood potassium remained in the normal range. After 3 days of treatment, the 24-hour dynamic electrocardiogram revealed sinus rhythm with an average heart rate of 82 beats/min, occasional ventricular premature beats, occasional ventricular premature beats, and no ST segment depression., Lessons: Although ozone therapy is widely used in the treatment of several diseases, adverse reactions should be given attention in clinical practice, especially in patients with chronic kidney disease., (Copyright © 2017 The Authors.

As a component of routine blood cell analyses, the quantity of neutrophils present is a proven predictor of morbidity and mortality in several clinical settings. However, whether episodes of acute kidney injury (AKI) are associated with higher neutrophil counts in vulnerable groups, such as chronic kidney disease (CKD) patients with hypertension, are unknown. This study was conducted to investigate the relationship between neutrophil counts and the incidence of surgery-related AKI in CKD patients with hypertension.This was a retrospective cohort study of the relationship between neutrophils and surgery-related AKI. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using logistic regression models.In total, 119 (11.9%) of 998 patients experienced surgery-related AKI during hospitalization from October 2008 to February 2013. We divided patients into 4 quartiles according to their neutrophil counts. After adjusting for multiple covariates, the patients in the 4th quartile of neutrophil counts had greater ORs for AKI compared to those in the 1st quartile. The incidence of AKI increased 1.59-fold for those patients with neutrophil counts ≥6.30 × 10/L. There was a positive linear association between the neutrophil count upon admission and the predicted probability of AKI. The cross-validation revealed a statistically significant predictive accuracy for AKI (area under the curve (AUC) = 0.68, 95% CI, 0.67-0.69). The interaction analyses revealed that higher neutrophil counts are associated with a heightened risk of AKI in the presence of diabetes (OR = 3.38, 95% CI, 1.06-10.80). There were no interactions between neutrophil counts and age (P = 0.371), sex (P = 0.335), estimated glomerular filtration rate (P = 0.487), systolic blood pressure (P = 0.950), diastolic blood pressure (P = 0.977), the presence of chronic heart failure (P = 0.226), or sepsis (P = 0.796).The neutrophil count upon admission, an index that is easily and rapidly measured, is valuable for the prediction of surgery-related AKI in CKD patients with hypertension, especially in those with diabetes., Competing Interests: The authors have no conflicts of interest to disclose.

Few studies have yet investigated the possible association between high-density lipoprotein cholesterol (HDL-C) and kidney function in elderly patients with primary hypertension. Accordingly, the aim of the present study was to evaluate the relationship between HDL-C and kidney function in elderly hypertension. A total of 14,644 elderly hypertensive subjects were enrolled in our cross-sectional study. The patients were categorized based on serum HDL-C level and glomerular filtration rate (GFR) value, respectively. One-way analysis of variance was used to compare the parameters among different groups. Bonferroni correction was performed for multiple comparisons. Analysis of covariance was used to control for confounding factors. The significance of difference between 3 groups and more was determined by chi-square test for categorical variables. Serum creatinine and uric acid were negatively related to HDL-C level, whereas GFR was positively related to HDL-C level in elderly hypertensive patients according to tertiles of HDL-C and tertiles of HDL-C/total cholesterol ratio (all P for trends <0.05). The male elderly hypertensive patients showed stronger relationship between HDL-C and renal function than the female elderly hypertensive subjects. Low HDL-C was associated with renal insufficiency and proteinuria in the hypertensive elderly (P < 0.05). The elderly "renal-hyperfiltrator" appeared to have lower HDL-C level, compared with the "normal renal-filtrator" (P < 0.05). There was an inverse "V" shape between HDL-C and GFR by GFR strata. Our results point out that there is an association of low HDL-C level with impaired kidney function in elderly hypertensive patients. Glomerular hyperfiltration may also affect HDL-C level and sex might be an influential factor for the association of HDL-C with kidney function in elderly hypertension.
