Epidemiological trends in community acquired acute Kidney Injury in Pakistan: 25 years Experience from a Tertiary Care Renal Unit.

BACKGROUND

Epidemiological studies of community acquired acute kidney injury (AKI) are sparse especially from South Asia and none has published from Pakistan. Reported incidences from different countries vary with use of different criteria of defining AKI. There is also variation found in different class of income countries, hospital based versus community based AKI.

METHODS

The current study was carried out in all adult AKI patients developing community acquired AKI and coming to a tertiary care renal institution from January 1990 to December 2014. This is a retrospective data collection from patient's records and AKI was defined according to KDIGO guidelines. Trends among different groups which are classified in medical, obstetrical and surgical were observed and presented.

RESULTS

In medical AKI there has been found a rise in toxic rhabdomyolysis, vivax malaria and dengue infection during later part of study. In obstetrical AKI observed continuous rise in numbers contributing to total AKI during these years. Surgical AKI included obstructed cases during initial ten years and only surgical trauma during later 15 years. Older age on presentation in medical AKI, and thrombocytopenia, deranged coagulation, deranged liver function, hyperkalemia, requirement of mechanical ventilation and multi organ failure in all groups remained predictors of higher mortality.

CONCLUSION

From Pakistan epidemiology for community acquired AKI has never been published on a large scale and this study would remain source of great information in this regard over coming years.
