Case Reports
Sympathomimetic syndrome, choreoathetosis, and acute kidney injury following "bath salts" injection.
"Bath salts" is a well known street drug which can cause several cardiovascular and neuropsychiatric symptoms. However, only one case of acute kidney injury has been reported in the literature. We present a case with sympathomimetic syndrome, choreoathetosis, gustatory and olfactory hallucinations, and acute kidney injury following the use of bath salts. ⋯ Bath salts contain 3,4-methylenedioxypyrovalerone, a psychoactive norepinephrine and dopamine reuptake inhibitor. Choreoathetosis in this patient could be explained through dopaminergic effect of bath salts or uremic encephalopathy. The mechanism for acute kidney injury from bath salts may involve direct drug effects though norepinephrine and dopamine-induced vasoconstriction (renal ischemia), rhabdomyolysis, hyperthermia, and/or volume contraction.

Modification of the mortality risk associated with acute kidney injury (AKI) necessitates recognition of AKI when it occurs. We sought to determine whether formal documentation of AKI in the medical record, assessed by billing codes for AKI, would be associated with improved clinical outcomes. ⋯ Formal documentation of AKI is associated with improved survival after adjustment for illness severity among patients with creatinine-defined AKI.

Colistin (polymyxin E) was developed ~ 60 years ago but was rarely used in clinical practice during the last 20 years because of concerns related to high rates of nephrotoxicity. However, it was recently reintroduced to clinical practice in many parts of the world for the treatment of multi-drug resistant gram-negative bacilli. In the current study, we evaluated the predictive capacity of urine neutrophil gelatinase-associated lipocalin (NGAL) for early diagnosis of acute kidney injury (AKI) in geriatric patients with urinary tract infection (UTI) receiving colistin therapy. ⋯ Our data suggest limited predictive capacity of urinary NGAL for early diagnosis of AKI in a large clinical setting of geriatric patients hospitalized for UTI and receiving the potentially nephrotoxic colistin. This finding is likely due to the powerful influence of UTI on NGAL levels in both patients with normal kidney function and those with a wide spectrum of acute or chronic kidney diseases.

Desmopressin acetate (DDAVP), a medication used in the treatment of bleeding and polyuric disorders, has the potential to cause hyponatremia when free water is not appropriately restricted with its use. This free water retention is reversible when DDAVP is discontinued. ⋯ In order to prevent rapid free water excretion, DDAVP and hypertonic saline were used concurrently. With close monitoring, this can be an effective treatment strategy in patients with DDAVP-induced hyponatremia.

Multicenter Study Comparative Study
Estimated glomerular filtration rate variability and risk of end-stage renal disease among patients with Stage 3 chronic kidney disease.
Dynamic changes in estimated glomerular filtration rate (eGFR) predict death among patients with chronic kidney disease (CKD). Whether variability in serial eGFR measurements is associated with risk of end stage renal disease (ESRD) has not been reported. ⋯ eGFR variability does not predict ESRD among patients with Stage 3 CKD.
