Although acute poisoning with ethylene glycol (EG) used in antifreeze mixtures is well known in man, only a few reports have described acute intoxication with diethylene glycol (DEG) and only one has mentioned oxaluria. Furthermore, there is no experimental evidence that DEG is metabolized into oxalate. The ability of ethanol infusions to prevent hepatic oxidation of DEG has not been proved. Moreover, failure of this treatment has been reported by some authors. In order to resolve such questions, Wistar male adult rats possessing a hepatic alcohol deshydrogenase were given a single oral dose of 15 ml/kg-1 DEG. Rats were either untreated or treated with hydration alone or associated with bicarbonate or ethanol. Urinary output, urinary oxalate excretion, acid-base balance in peripheral blood and renal histology were studied. Acute poisoning induced metabolic acidosis, polyuria, hyperoxaluria with renal tubular necrosis and a 66% mortality. Massive hydration improved acidosis and prognosis, but mortality and renal lesions were avoided only when bicarbonate or ethanol were added. Only ethanol significantly decreased oxaluria. In acute DEG poisoning, both the mechanism and the treatment appear to be the same as in acute EG intoxication.

Ethylene glycol (EG) may be consumed accidentally or intentionally, usually in the form of antifreeze products or as an ethanol substitute. EG is metabolized to toxic metabolites. These metabolites cause metabolic acidosis with increased anion gap, renal failure, oxaluria, damage to the central nervous system and cranial nerves, and cardiovascular instability. Early initiation of treatment can reduce the mortality and morbidity but different clinical presentations can cause delayed diagnosis and poor prognosis. Herein, we report a case with the atypical presentation of facial paralysis, hematuria, and kidney failure due to EG poisoning which progressed to end stage renal failure and permanent right peripheral facial nerve palsy.

Xanthium strumarium has traditionally been used in the treatment of urolitiasis especially by the rural people in India, but its antiurolithiatic efficacy was not explored scientifically till now. Therefore, the present study was designed to validate the ethnic practice scientifically, and explore the possible antiurolithiatic effect to rationalize its medicinal use. Urolitiasis was induced in hyperoxaluric rat model by giving 0.75% ethylene glycol (EG) for 28days along with 1% ammonium chloride (AC) for first 14days. Antiurolithiatic effect of aqueous-ethanol extract of Xanthium strumarium bur (xanthium) was evaluated based on urine and serum biochemistry, oxidative/nitrosative stress indices, histopathology, kidney calcium and calcium oxalate content and immunohistochemical expression of matrix glycoprotein, osteopontin (OPN). Administration of EG and AC resulted in hyperoxaluria, crystalluria, hypocalciuria, polyurea, raised serum urea, creatinine, erythrocytic lipid peroxidise and nitric oxide, kidney calcium content as well as crystal deposition in kidney section in lithiatic group rats. However, xanthium treatment significantly restored the impairment in above kidney function test as that of standard treatment, cystone. The up-regulation of OPN was also significantly decreased after xanthium treatment. The present findings demonstrate the curative efficacy of xanthium in ethylene glycol induced urolithiasis, possibly mediated through inhibition of various pathways involved in renal calcium oxalate formation, antioxidant property and down regulation of matrix glycoprotein, OPN. Therefore, future studies may be established to evaluate its efficacy and safety for clinical use.
