MO1055JUDICIOUS DIALYSIS DISCONTINUATION IN CHRONIC KIDNEY DISEASE: LENDING MORE TIME TO ECONOMICALLY BURDENED PATIENTS IN DEVELOPING COUNTRY

Abstract

Abstract Background and Aims Chronic kidney disease (CKD) is important public health problem owing to its high prevalence, morbidity, mortality and socio-economic burden. Patients with end stage kidney disease need to be on kidney replacement therapy which significantly impacts livelihood. Annual average cost of treatment for patients on dialysis is reported to be USD 3151 in developing country like India. It’s quiet high given per capita income of USD 1670 Method One hundred fifty one CKD Stage 5D patients from Punjab and Rajasthan states, North India were studied in this cross-sectional study. Patients initiated on dialysis within 3 months or protein energy wasting (as per criteria proposed by ISRNM) were excluded. Asymptomatic willing patients, clinically stable for at least 3 months and with pre-dialysis serum Creatinine <6mg/dl, serum potassium <5mg/dl were given a trial for dialysis discontinuation after informed written consent. Biochemical and hemodynamic parameters were measured weekly for 4 weeks and later once monthly. Patients who developed uremic features or rapid rise in serum creatinine were restarted on dialysis. Results Fourteen (9.27%) asymptomatic patients with well controlled blood pressure were discontinued from dialysis. Out of them, thirteen patients were on hemodialysis and one on peritoneal dialysis. Twelve (85.71%) out of them were presumed chronic interstitial nephritis while two (14.28%) were autosomal dominant polycystic kidney disease. Mean age of patients was 52.5 years (SD ±18.14 years). Most patients (11/14) were on three or more anti-hypertensive. Mean dialysis vintage was 8.14 months (range 4-16 months). Most patients were non-compliant to dialysis (Mean frequency once in seven days). Two patients were on once in two week dialysis schedule. Mean 24 hour urine output (calculated over 1 week) was 1500ml. Mean baseline serum creatinine was 4.4 mg/dl (SD ±1.06 mg/dl). Mean pre-dialysis serum potassium was 4.5 mg/dl (SD ±0.42 mg/dl). Post-discontinuation serum creatinine levels has been outlined in figure 1. Mean distance of dialysis centre from residence was 83.43 Km (range 1-240 km). One patient need to be restarted on dialysis at fourth week of dialysis discontinuation. Rest patients remained symptom-free and tolerated well. Conclusion CKD Stage5D patients should be regularly screened for residual renal function. Recovery of renal function could be seen in some (<10%) cases. Dialysis discontinuation in these cases would decrease their financial and stress burden. However, these cases should be monitored closely and followed-up regularly
