Acute kidney injury (AKI) increases the risk of morbidity, mortality, and progression to chronic kidney disease (CKD). There are few data on the risk of CKD following community-acquired AKI (CA-AKI) and its predictors from developing countries. We evaluated the association of a panel of serum and urine biomarkers at the time of hospital discharge with 4-month renal outcome in CA-AKI. Patients of either sex, aged between 18 and 70 years, with no underlying CKD, and with CA-AKI were recruited at the time of discharge from hospital in this prospective observational study. Levels of serum and urine biomarkers were analyzed and association between these markers and development of CKD, defined as eGFR < 60 ml/min/1.73 m2 or dialysis dependence at 4 month after discharge, were analyzed using multivariate logistic regression analysis and penalized least absolute shrinkage and selection operator logistic regression. Out of a total 126 patients followed up for 4 months, 25 developed CKD. Those who developed CKD were older (p = 0.008), had higher serum creatinine (p < 0.001) and lower serum albumin (p = 0.001) at discharge. Adjusted logistic regression showed that each 10% increase in standardized serum myo-inositol oxygenase (MIOX) level increased the odds of progression to CKD by 13.5%. With 10% increase in standardized urine Neutrophil gelatinase-associated lipocalin (NGAL), serum creatinine and urine protein creatinine ratio (uPCR), increase in the odds of progression to CKD was 10.5%, 9.6% and 8%, respectively. Multivariable logistic model including serum MIOX, discharge serum creatinine and discharge uPCR, was able to predict the progression of CKD [AUC ROC 0.88; (95% CI 0.81, 0.95)]. High level serum MIOX levels at the time of discharge from hospital are associated with progression to CKD in patients with CA-AKI.

Drug trafficking is an international problem. Over years it has increased in prevalence and concealment methods. Body packers swallow wrapped packets of illicit drugs, mainly cocaine and heroin and try to conceal them from security personnel. They present to physicians either as body packer syndrome with symptoms of intoxication or asymptomatically on suspicion of drug concealment, for observation. We report a case of middle aged unknown male, found in comatose state on road side by Delhi police (India), brought to our emergency without any signs of injury. Initially organophosphate toxidrome was suspected, later confirmed to be opiod toxidrome with internal concealment of many balloons (of polythene) wrapped packets of heroin. On failure of conservative removal, he underwent laparotomy with complete removal of all the packets. He was discharged in stable condition and handed over to the police. This is the first case report of live heroin body packer syndrome from India.
