KARACHI (APP) - Pakistan with 224 dialysis centres and 988 dialysis machines in 61 of its cities witnesses a constant surge in the number of diabetic patients with end stage renal failure. The Fourth Dialysis Registry of Pakistan 2007-2008, released by the Kidney Foundation here Friday shows that the number of End Stage Renal Diabetics (ESRD) grew from 4393, in 2006-2007, to 6127 in 2007-2008. This was in a scenario where number of dialysis centres supported by the community decreased from 20.08 % in 2006 to 12.94 % in 2007- 2008. Twenty-one of the 224 dialysis centres were rendered non-functional due to administrative and financial constraints, 17 of the centres did not share the data while another 14 were closed down, due to un-disclosed reasons, in 2007-2008. It was in the same year that 23 new dialysis centres were established in the country, none in Pakistan Occupied Kashmir. 11 of these were government-funded, four were semi- government, eight in private sector while none were supported by the philanthropists. The 195 dialysis centres, operational during 2007-2008, were supervised by a total number of 343 doctors and 553 technicians against an acute shortage of dieticians, coming to mere 365 (20.57%) and 66 social workers for 175 centres.   Chief Executive and Secretary, The Kidney Foundation Prof. S.A. Jaffar Naqvi, in the preface of registry document urged for a realistic and definite effort towards preventing diabetes and hypertension, which are the main causes of ESRD. Reduction of weights, exercise/ walk, less salt, proper control of Blood Pressure (120/70 mmHg) and diabetes (Fasting - 110, Random - 140 to 160 during 24 hours) can help avoid ESRD, said the senior nephrologist. Prof. Naqvi said the use of vegetable is also helpful and thatweight reduction, exercise, controlled salt intake and due care towards blood pressure or/ and diabetes required least expenses. "Available drugs for hypertension and diabetes do not cost more than Rs 1500 per year," he said. Dialysis, a life saving procedure is often beyond the means of an average Pakistani and most of the facilities are being either managed via government funds or philanthropic support. Data compiled regarding mortality on dialysis showed 24.35 % deaths, with highest in NWFP (53.60 %), followed by Pakistan Occupied Kashmir (40%), Balochistan (32.04%), Islamabad (26.28%), Punjab (21.47%) and Sindh (20.23%). Cardiac problems (59.58 %) was the major cause of death for 1492 patients on dialysis who expired in 2007-2008. It was followed by Infections (22.65 %) and other factors (17.76 %).
