Background: Patients presenting with acute interstitial nephritis (AIN) of unknown aetiology, probably the earliest presentation of chronic kidney disease of unknown aetiology (CKDu), have been treated with oral prednisolone and doxycycline by physicians in Sri Lanka. This trial assessed the effectiveness of prednisolone and doxycycline based on eGFR changes at 6 months in patients with AIN of unknown aetiology.
Method: A randomized clinical trial with a 2 × 2 factorial design for patients presenting with AIN of unknown aetiology (n = 59) was enacted to compare treatments with; A-prednisolone, B-doxycycline, C-both treatments together, and D-neither.
Introduction: The majority of published data on chronic kidney disease of uncertain etiology (CKDu) is on asymptomatic patients who were detected in screening programs. The clinicopathological profile of a group of patients presenting with acute symptoms and renal dysfunction from CKDu endemic regions in Sri Lanka was studied.
Methods: 59 patients > 10 years of age with backache, feverish fatigue feeling, dysuria, joint pain, or dyspepsia, singly or in combination with elevated serum creatinine (> 116 and > 98 µmol/L for male and females, respectively) were included in the study.
Hump-nosed viper (Hypnale species) bites are common in Sri Lanka and a proportion of these bites lead to coagulation abnormalities and acute kidney injury (AKI). We observed thrombotic microangiopathy (TMA) among some of these patients, but its contribution to severity of AKI and other morbidities remains unknown. Thus, we report a case series of TMA following hump-nosed viper bite addressing the complications and renal out comes in Sri Lanka.
