Pregnancy in patients with renal transplants in Malaysia.

There were 72 pregnancies in 46 renal transplants (RTs) between 1984 and 2001, 89% from living donors, 11% cadaveric. Mean age at RT was 26.9 +/- 4.3 years and at pregnancy 30.7 +/- 4.7 years. Mean time to pregnancy after RT was 4.5 +/- 3.1 years. 54% were unplanned. 45 (63%) resulted in surviving infants, 37% delivered by Caesarean section. 35% were premature. Mean birth weight was 2.38 +/- 0.57 kg. 64% were on cyclosporine. No patient had an acute rejection during pregnancy; 38% had pre-existing hypertension. Complications include urinary infection (13%), proteinuria (15%) and preeclampsia (15%). Mean serum creatinine before pregnancy was 112.7 +/- 32.6 umol/l, 1 year post-pregnancy it was 119.4 +/- 38.7. The mean time of follow up of mothers is 4.9 +/- 3.5 years. 10 year graft survival was 83% and patient survival 94%.

Outcome of 235 renal transplant recipients followed up at ministry of health hospitals in the State of Johor.

Retrospective analysis was done on 235 recipients, 133 males and 102 females, who were transplanted between 25th September 1979 and 25th June 1999. 85.1% were Chinese, 7.7% were Indians and 7.2% Malays. 23% (54) were living related renal transplants (LRRT) all except 5 done at Hospital Kuala Lumpur. 60% (141) were living unrelated donor renal transplants (LURT) done in India. 17% (40) were cadaveric transplants (CADT) (all done in China except 2 at Hospital Kuala Lumpur and one in London). 97% (228) were first transplants. Primary renal disease was unknown in 69.4%, 17% (40) glomerulonephritis, 5.5% diabetic nephropathy and 8.1% 19 others. All were on prednisolone, 93.2% were on azathioprine and 96.6% were on cyclosporin A. The acute rejection rate was 23.4% (55 episodes). Patient survival was 88% at five years and patients alive with functioning graft was 84% at 5 years. LRRT had significantly better survival compared to LURT. 34 grafts were lost to chronic allograft nephropathy. 46 recipients died (33 died with functioning graft).

Outcome of 85 lupus nephritis patients treated with intravenous cyclophosphamide: a single centre 10 year experience.

Retrospective analysis was done on 85 patients (76 female, 9 male) with lupus nephritis who started intravenous cyclophosphamide between 1/1/1989 and 31/12/1998. The initial renal biopsy (World Health Organisation) classification was III (4.7%), IV (89.4%) and V (5.9%). Average serum creatinine at time of biopsy was 0.12 +/- 0.12 mmol/l. Median duration of nephritis before biopsy was 2 months (range 0-133). Median duration of follow-up from time of biopsy to outcome (death or end-stage renal failure) was 3.3 years (range 0.3-11.8). Nineteen patients died. The calculated proportion alive at 5 years was 75% and at 10 years 64%. The calculated proportion alive with renal function was 74% and 54% at 5 and 10 years respectively. Fifty-two patients completed cyclophosphamide therapy at the end of the study. There were ten episodes of herpes zoster, the most common infection seen. No malignancy was reported.

Cost effectiveness evaluation of the Ministry of Health Malaysia dialysis programme.

We determine the cost effectiveness of centre and home haemodialysis (HD), continuous ambulatory peritoneal dialysis (CAPD) and intermittent peritoneal dialysis (IPD) treatment in the Ministry of Health (MOH) programme. The viewpoint taken for this evaluation is that of MOH. Cost categories identified were capital cost, dialysis operational cost, medical cost and general hospital cost. Cost estimates were mostly based on actual resource utilisation. Life years saved were estimated based on Dialysis Registry data on 2480 HD and 732 CAPD patients. Overall, the cost-effectiveness ratio (CER) of centre HD was RM21620/life year saved. Those of home HD, CAPD and IPD were RM23375, RM30469 and RM36016 respectively. Sensitivity analyses did not change the ranking of the CER. We conclude the MOH dialysis programme was cost-effective, and among the various dialysis modalities centre HD was the most cost-effective.

Outcome assessment of the Ministry of Health Malaysia dialysis programme.

We describe the outcomes on haemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) provided by the Ministry of Health (MOH). The assessment was based on data from the Malaysian Dialysis Registry on 2480 HD and 732 CAPD patients who commenced dialysis between 1980 and 1996. Young patients (age < 40) have remarkable long term survival (life expectancies of 16 years on HD, 18 years on CAPD). Adjusting for background mortality, relative survival of older patients was as good as younger ones. Diabetics did poorly. 52% of HD and 26% of CAPD patients were employed in 1996. 71% of HD patients scored 10(normal) on QL index (a measure of quality of life) while 60% of CAPD patients have similar score. Differences in rehabilitation and QL index scores by age, gender and diabetes were also observed. Outcomes of dialysis in the MOH programme are reassuring.

Acute renal failure requiring dialysis--a 5 year series.

A retrospective review of 246 patients with established acute renal failure (ARF) needing dialysis from 1990-1994 is reported from Hospital Sultanah Aminah, Johor Bahru. Peritoneal dialysis was more commonly used than haemodialysis or haemofiltration. Patients on mechanical ventilation in Intensive Care Unit (ICU) who were hypercatabolic and fluid overloaded were treated with haemofiltration. Males outnumbered females by a ratio of 1.5:1. The majority were Malays (61.4%). Most patients were from the district of Johor Bahru, but 41.5% were from other districts in the Johor state. The mean age was 47.1 years (SD 18.2). The ARF was caused by acute tubular necrosis in 55.3%, post-renal obstruction in 22.8%, nephrotoxins in 5.7% and other causes in 16.2%. The proportions of patients referred from the medical, surgical and obstetric and gynaecology units were 50.8%, 45.5% and 3.7% respectively. The mortality rate was 48%. Patients with established ARF should be dialysed early as they tolerate uraemia poorly. Prevention is by prompt treatment of patients with sepsis, avoidance of hypovolaemia and nephrotoxic drugs.

A registry of patients with end stage renal disease--the experience at hospital Sultanah Aminah, Johor Baru.

A registry of patients with end stage renal disease was started from 1st January 1990 at Hospital Sultanah Aminah, Johor Baru. There were 126 patients in 1990 and 129 in 1991. The peak age was 31 to 60 years old; males outnumbered females 1.5:1. Forty-three to fifty-six percent presented with small kidneys. Seventeen to twenty percent of patients had diabetes mellitus. In 1991, the racial distribution of patients was Malay: 50.4%, Chinese: 39.5%, Indian: 7.8% and others: 2.3%. The incidence of end stage renal disease in Johor Baru district was 79 per million per year in 1990 and 86 per million in 1991.
