Among the untoward side effects of kanamycin, ototoxicity is particularly frequent. Premature infants may be at increased risk because of their low glomerular filtration rate. Previous studies have revealed decreased sensory neural hearing in 0% to 19% of term and premature infants who received kanamycin. Because only one study specifically investigated this question in premature infants,1 we have performed an audiometric survey in children aged 4 to 10 years (mean 7.5 years) who received kanamycin while premature and in age-matched controls.

Sickle Cell Nephropathy

Background. Sickle cell nephropathy (SCN) is a serious complication of sickle cell anaemia (SCA) with asymptomatic onset in childhood and possible progression to chronic kidney disease (CKD). In Southeast Nigeria, few studies have evaluated renal function in paediatric SCA patients for early detection of renal impairment and early intervention to reduce morbidity and mortality. Therefore, this study evaluated the renal function of paediatric SCA patients in a steady state based on glomerular filtration rate and urinalysis findings (proteinuria and haematuria). Methods. A cross-sectional study of consecutively recruited sixty haemoglobin SS (HbSS) children in a steady state and sixty age- and sex-matched haemoglobin AA (HbAA) controls aged 2–18 years was done. Renal function of HbSS subjects was evaluated using estimated glomerular filtration rate (eGFR) which was compared with healthy HbAA subjects. The prevalence of significant proteinuria and haematuria, its association with eGFR, and the effect of past sickle cell crisis (in the preceding 24 months) on renal function were also evaluated. Results. Mean eGFR was significantly higher in HbSS subjects than in the HbAA subjects (p=0.001) and decreased with age. Significant proteinuria and haematuria were more prevalent in the HbSS group (3.4% and 6.7%, respectively) compared to the HbAA subjects (0% and 0%, respectively) (p=0.496 and 0.119, respectively). No significant association was observed between eGFR and proteinuria (p=1.000) or haematuria (p=1.000). There was a positive correlation between eGFR and frequency of past painful crisis that required hospitalization (r=0.138, p=0.295) and between eGFR and frequency of blood transfusion (r=0.679, p≤0.001). Conclusions. Asymptomatic paediatric HbSS (SCA) patients had higher mean eGFR indicating an increased risk of nephropathy. There was no association between eGFR and proteinuria or haematuria. Frequent sickle cell crises especially one requiring transfusion were positively correlated with hyperfiltration.

Cardiovascular Outcome Trial

SAVOR-TIMI 53 was the first FDA-mandated cardiovascular outcome trial to be presented and published. It compared saxagliptin and placebo in 16,492 patients with type 2 diabetes. SAVOR-TIMI 53 demonstrated non-inferiority for major cardiovascular events (cardiovascular death, myocardial infarction, stroke) but not superiority. An unexpected statistically significant increase in adjudicated hospitalisation for heart failure was seen in the saxagliptin group. Post hoc analysis demonstrated that subjects at greatest risk for hospitalisation for heart failure had previous heart failure, an estimated glomerular filtration rate <60 mL/min, or elevated baseline levels of N-terminal pro-B type natriuretic peptide. As other dipeptidyl peptidase 4 (DPP-4) inhibitors are available which have not been associated with an increased risk of hospitalisation for heart failure, saxagliptin should be avoided in patients with heart failure or a reduced estimated glomerular filtration rate.

Metabolic Equivalent Of Task

In previous studies, it has been documented that a short reproductive period is associated with a higher risk of diabetes, cardiovascular disease, and chronic kidney disease. This study aims to investigate the association of the reproductive period length with decreased renal function. This study obtained data from “the Shanghai Suburban Adult Cohort and Biobank”. An estimated glomerular filtration rate (eGFR) below 60 mL/min/1.73 m2 indicated decreased renal function during follow-up. Participants were grouped into quintiles by reproductive period. Logistic regression analysis was performed to examine the association between the reproductive period and decreased renal function. A total of 5503 menopausal women with baseline eGFR > 60 mL/min/1.73 m2 were included. Age, eGFR, and metabolic equivalent of task (MET) at baseline were 61.0 (range, 36.0–74.0) years, 92.2 (range, 60.1–194.5) mL/min/1.73 m2, and 1386 (range, 160–6678), respectively. A reproductive period of 37–45 years was associated with a lower risk of decreased eGFR (OR: 0.59, 95% CI: 0.35–1.00, p = 0.049) after adjusting for confounding variables. METs decreased the risk of decreased eGFR in women with a reproductive period of 37–45 years (OR: 0.43, 95% CI: 0.23–0.81, p = 0.010). Women with a longer reproductive period have a lower risk of decreased renal function. METs had an opposite influence on renal function in women with longer (decreased risk) or shorter (increased risk) reproductive periods.

Background: The effects of the estimated glomerular filtration rate (eGFR) and cystatin C on clinical outcomes on intracerebral hemorrhage (ICH) remain unclear. We investigated the associations of eGFR and cystatin C with 3-month functional outcome and all-cause mortality in acute ICH patients. Methods: A total of 365 patients with acute ICH were enrolled. Serum creatinine and cystatin C levels were measured within 24 h of admission. Outcomes at 3-month were evaluated by interviews with patients or their family members. Poor functional outcome was defined as a modified Rankin Scale score ≥3. Results: During the 3-month follow-up, 154 patients experienced poor functional outcome, and 48 patients died from all causes. Low eGFR level was associated with poor outcome (adjusted OR 8.95; 95% CI 2.13-37.66; p-trend = 0.045) and all-cause mortality (adjusted hazards ratio (HR) 5.10; 95% CI 2.00-13.03; p-trend = 0.001). Additionally, a high cystatin C level was also found to be associated with all-cause mortality (adjusted HR 4.01; 95% CI 1.09-14.72; p-trend = 0.015). However, no significant association between cystatin C and poor functional outcome was observed (p-trend = 0.615). Conclusions: Low eGFR at baseline predicts poor functional outcome and all-cause mortality at 3-month in acute ICH patients. Also, high cystatin C was associated with increased risk of mortality but not with poor functional outcome.
