In the 10-year period from October 1977 to July 1987, 149 cases of primary IgA nephropathy were histologically confirmed through renal biopsies in the Department of Pathology, University Hospital, Kuala Lumpur. The ages of these patients ranged from 5 to 72 years, with the majority in the 20-30 year age group. There was no sex preponderance. The ethnic distribution showed a significant predominance of Chinese with 107 (71.8%) Chinese, 24 (16.1%) Malays, 15 (10.1%) Indians and 3 others. A wide range of renal glomerular pathology was seen, the commonest being diffuse mesangioproliferative glomerulonephritis (59.1%). Focal proliferative glomerulonephritis (14.1%) followed by minimal change glomerulonephritis (10.7%) were next in order of frequency. Immunofluorescence studies consistently demonstrated heavy and predominant IgA deposition in the mesangium. Weak deposition of C3, IgG and IgM were also observed in various combinations.
A study on the binding interaction of lectins from Artocarpus heterophyllus (jacalin), Glycine max and Sambucus nigra with standardised quantity of IgA from the IgA nephropathy patients and normal controls was performed. The Glycine max lectin demonstrated higher affinity towards the serum IgA of IgAN patients as compared to normal controls. However, the affinity binding was lower in cases ofjacalin and the Sambucus nigra lectin. When serum samples were treated with neuraminidase, the differential jacalin affinity binding between IgA1 of patients and normal controls was abrogated. Our data are in support of the view that the O-linked oligosaccharide moieties of the patients IgA1 were generally lacking in galactose and sialic acid residues.
Four recent cases of dengue fever with severe, unusual clinical manifestations are described. Two of these cases had features of fulminant hepatitis and encephalopathy; one of these cases was fatal. The two remaining cases showed hepatitis with renal impairment. The significance and importance of these unusual manifestations of dengue disease are discussed.
This cross-sectional study investigated the use of alternative medications to alleviate menopause-related symptoms among Malay, Chinese, and Indian women of Ipoh city. The prevalence, types, effectiveness, and associated factors were determined. The prevalence of alternative medication use was 41.4%. Evening primrose oil (EPO) was the most popular medication used (18.1%), followed by soy-based products (12.3%), green tea (6.8%), and gingko (5.8%). The medication was reported to be highly effective by 58.3% of soya bean diet users and 41.1% of EPO users. Significant variables associated with the use were Chinese or Indian ethnicity (P < .001), age between 50 and 54 years (P < .01), lower self-health rating (P < .05), education level of diploma or professional degree (P < .05), employment as professionals or entrepreneurs (P < .05), and the use of hormone replacement therapy (P < .05). Regression analysis showed that Chinese and Indians had significantly higher odds for the use than Malays (Chinese: odds ratio [OR] = 4.33, 95% confidence interval [CI] = 2.392-7.837; Indians: OR = 3.248, 95% CI = 1.586-6.654).
