The pattern of glomerulonephritis (GN) consisting of 1057 renal biopsies is presented. Primary GN accounted for 91% and secondary GN 9% of which the commonest is lupus nephritis. Asymptomatic haematuria and proteinuria was the commonest mode of presentation (41%), gross haematuria 9%, nephrotic syndrome 29% while 5.5% presented with renal impairment and 4.3% with hypertension. Mesangial proliferative GN is the commonest histopathological lesion forming 66% of all primary GN. Minimal Lesion, Focal Global Sclerosis and Focal Segmental Glomerulosclerosis accounted for 7% each. Membranous GN was uncommon (3%) while Mesangiocapillary GN, Diffuse Endocapillary GN and Crescentic GN were even rarer. If the presenting feature was asymptomatic haematuria and proteinuria the likely diagnosis was IgA nephritis, and, if nephrotic syndrome it was likely to be Idiopathic Mesangial Proliferative GN but with negative staining on immunofluorescence. The course and prognosis of the various forms of GN are next discussed. Nephrotic syndrome with Minimal Lesion has an excellent prognosis while Crescenteric GN usually carries a grim prognosis. Finally, factors affecting the progression of IgA nephritis, the commonest form of GN occurring in Singapore are examined. Patients who developed renal failure ran two different courses; one was a slowly progressive course over an average of 7.7 years before reaching end stage renal failure (ESRF), while the other was a more rapid decline to ESRF within an average of 3.3 years where severe uncontrolled hypertension seemed to be the major adverse factor. 9% had renal impairment at the end of a follow up of 50 + 1/2 - 34 months while 5% progressed to ESRF. The cumulative renal survival was 91% after 6 years with no further loss up to 14 years. Unfavourable long term prognostic indices were proteinuria of more than 2 gms, hypertension, crescents on renal biopsy, severe segmental sclerosis and medial hypertrophy of blood vessels.

Five patients aged 1.1 - 4.3 years, affected by nephritis secondary to infection of ventriculo-atrial shunt are presented. The time lag between the occurrence of shunt infection and diagnosis of nephropathy varied from 1 to 12 months. In four patients "Staphylococcus epidermidis" was isolated from blood and CSF cultures, and "Staphylococcus aureus" in another one. Renal lesion presented as hematuria and proteinuria, and two patients developed a nephrotic syndrome. Hypertension was present in three patients. C'2 and D'4 hypocomplementemia was a constant feature in the acute stage of the disease. Endocapillary glomerulonephritis was observed in three patients and endo-extracapillary glomerulonephritis in one (70% of crescent formations). After shunt removal and antibiotic administration a favorable clinical course was followed in three patients, with remission of nephropathy signs. The fifth patient (non biopsied) died in the course of a septic process, having kept until then a good renal function.
