AbstractBackgroundInformation on kidney impairment in patients with coronavirus disease 2019 (COVID-19) is limited. This study aims to assess the prevalence and impact of abnormal urine analysis and kidney dysfunction in hospitalized COVID-19 patients in Wuhan.MethodsWe conducted a consecutive cohort study of COVID-19 patients admitted in a tertiary teaching hospital with 3 branches following a major outbreak in Wuhan in 2020. Hematuria, proteinuria, serum creatinine concentration and other clinical parameters were extracted from the electronic hospitalization databases and laboratory databases. Incidence rate for acute kidney injury (AKI) was examined during the study period. Association between kidney impairment and in-hospital death was analyzed.ResultsWe included 710 consecutive COVID-19 patients, 89 (12.3%) of whom died in hospital. The median age of the patients was 63 years (inter quartile range, 51-71), including 374 men and 336 women. On admission, 44% of patients have proteinuria hematuria and 26.9% have hematuria, and the prevalence of elevated serum creatinine and blood urea nitrogen were 15.5% and 14.1% respectively. During the study period, AKI occurred in 3.2% patients. Kaplan–Meier analysis demonstrated that patients with kidney impairment have higher risk for in-hospital death. Cox proportional hazard regression confirmed that elevated serum creatinine, elevated urea nitrogen, AKI, proteinuria and hematuria was an independent risk factor for in-hospital death after adjusting for age, sex, disease severity, leukocyte count and lymphocyte count.ConclusionsThe prevalence of kidney impairment (hematuria, proteinuria and kidney dysfunction) in hospitalized COVID-19 patients was high. After adjustment for confounders, kidney impairment indicators were associated with higher risk of in-hospital death. Clinicians should increase their awareness of kidney impairment in hospitalized COVID-19 patients.

Cutaneous Vesicostomy

We report a case of VURD syndrome in a three day old neonate who was diagnosed with hydronephrosis on a prenatal ultrasound. Severe tortuosity and dilation of the upper urinary tracts in the presence of progression of hydronephrosis or a persistently elevated creatinine may favor a proximal urinary diversion rather than primary valve ablation or cutaneous vesicostomy. Because of a persistently elevated serum creatinine, a nonfunctioning kidney with grade 4/5 vesicoureteral reflux and worsening contralateral hydronephrosis despite lower tract drainage, a left cutaneous pyelostomy was performed, contralateral to the kidney involved with VURD. Postoperatively the serum creatinine stabilized at 1.0 mg/dl and decreased to 0.3 mg/dl at one month of age.

Lower Urinary

One hundred patients with lower urinary tract obstruction (LUTO) seen over a 10-month period were prospectively studied. Nineteen (19%) had an elevated serum creatinine (>125 μmol/l); 13% had benign prostatic hyperplasia (BPH); 4% had urethral strictures; and two had congenital anomalies. Though urethral strictures are more common than BPH they cause less renal impairment, probably because the patients are younger and also because a urinary fistula may form proximal to the stricture when the intravesical pressure rises very high. Eighty per cent of the patients with renal impairment had a urinary tract infection (UTI), and in these the reduction in serum creatinine following relief of obstruction was slow and erratic. In three patients who did not have UTI the serum creatinine dropped steadily at a rate which varied from 6.8–845 μmol/l/week following continuous bladder drainage and appropriate supportive management. All patients with elevated serum creatinine had delayed surgery and required prolonged preoperative hospitalization, with a resultant sharp increase in the cost of their treatment.

Beneficial Effects

The risk of serious side-effects such as nephrotoxicity is the principal limitation of gentamicin (GEN) therapeutic efficacy. Oxidative stress is considered to be an important mediator of GEN-induced nephrotoxicity. The present study was designed to evaluate the efficacy of the combination of melatonin (MT) plus atorvastatin (ATO) against GEN-induced nephrotoxicity in rats. We utilized 30 male Wistar albino rats allocated in 5 groups, each containing 6 rats: control, GEN (100 mg/kg/day), ATO (10 mg/kg/day) + GEN, MT (20 mg/kg/day) + GEN, and ATO (10 mg/kg/day) plus MT (20 mg/kg/day) + GEN. Kidney weight, serum creatinine and urea concentration, renal ROS, MDA, GSH levels, SOD, and CAT activity were determined. GEN-induced nephrotoxicity was evidenced by marked elevations in serum urea and creatinine, kidney weight, renal ROS, and MDA levels and reduction in renal GSH level, SOD and CAT activity. MT pretreatment significantly lowered the elevated serum creatinine concentration, kidney weight, renal ROS and MDA levels. However ATO could not reduce these parameters, but similarly to MT, it was able to enhance the renal GSH level, CAT and SOD activity. In addition, a combination therapy of MT plus ATO enhanced the beneficial effects of ATO, while not changing the effects of MT effects or even improving them. The present study indicates that a combination therapy of MT plus ATO can attenuate renal injury in rats treated with GEN, possibly by reducing oxidative stress, and it seems that MT can enhance the beneficial effects of ATO.
