Inflammatory diseases of the bowel: a Malaysian experience

Ti TK

Aust N Z J Surg, 1979 Aug;49(4):428-31.
PMID: 115452

A 10-year experience in the diagnosis and treatment of 92 patients with inflammatory bowel diseases in Kuala Lumpur is described. Tuberculosis (34 cases) was the most common inflammatory bowel disease of surgical importance. The clinical presentation of tuberculous enteritis and Crohn's disease is similar, though tuberculosis is strongly suggested by associated pulmonary disease and radiological evidence of caecal involvement. The finding of 10 cases each of Crohn's disease and ulcerative colitis is in keeping with an increased awareness of these conditions in a developing urban society where facilities exist for thorough investigation of diarrhoeal diseases. Amoebiasis sometimes causes a granulomatous lesion simulating carcinoma. Diverticular disease of the colon as known in the West is of very rare occurrence.

Fulltext Ulcerative colitis in Malaysians: a review of 23 patients

PMID: 2814543

Twenty-three patients with ulcerative colitis are reported from Kuala Lumpur, Malaysia. Sixteen were newly diagnosed over a six-year period between 1982 and 1987. The disease was commoner in men (16 men : 7 women). The peak age of onset was in the third decade. The ethnic distribution of the patients was 10 Malays, eight Indians and five Chinese making the disease relatively commoner amongst Indians. The extent of colonic involvement varied and six (26%) had a total colitis. Extra-intestinal manifestations were seen in seven patients. Diagnosis was delayed for over 10 years in four. Colorectal cancer was not seen. There was no mortality. Ulcerative colitis remains an uncommon disease amongst Malaysians. During the same period, only four male patients with Crohn's colitis were seen.

Fulltext Colonic Mucosal Transcriptomic Changes in Patients with Long-Duration Ulcerative Colitis Revealed Colitis-Associated Cancer Pathways

BACKGROUND AND AIMS: Patients with ulcerative colitis [UC] with long disease duration have a higher risk of developing colitis-associated cancer [CAC] compared with patients with short-duration UC. The aim of this study was to identify transcriptomic differences associated with the duration of UC disease.
METHODS: We conducted transcriptome profiling on 32 colonic biopsies [11 long-duration UC, ≥20 years; and 21 short-duration UC, ≤5 years] using Affymetrix Human Transcriptome Array 2.0. Differentially expressed genes [fold change > 1.5, p < 0.05] and alternative splicing events [splicing index > 1.5, p < 0.05] were determined using the Transcriptome Analysis Console. KOBAS 3.0 and DAVID 6.8 were used for KEGG and GO analysis. Selected genes from microarray analysis were validated using qPCR.
RESULTS: There were 640 differentially expressed genes between both groups. The top ten upregulated genes were HMGCS2, UGT2A3 isoforms, B4GALNT2, MEP1B, GUCA2B, ADH1C, OTOP2, SLC9A3, and LYPD8; the top ten downregulated genes were PI3, DUOX2, VNN1, SLC6A14, GREM1, MMP1, CXCL1, TNIP3, TFF1, and LCN2. Among the 123 altered KEGG pathways, the most significant were metabolic pathways; fatty acid degradation; valine, leucine, and isoleucine degradation; the peroxisome proliferator-activated receptor signalling pathway; and bile secretion, which were previously linked with CAC. Analysis showed that 3560 genes exhibited differential alternative splicing between long- and short-duration UC. Among them, 374 were differentially expressed, underscoring the intrinsic relationship between altered gene expression and alternative splicing.
CONCLUSIONS: Long-duration UC patients have altered gene expressions, pathways, and alternative splicing events as compared with short-duration UC patients, and these could be further validated to improve our understanding of the pathogenesis of CAC.

CONTEXT: The tuber of Amorphophallus paeoniifolius (Dennst.) Nicolson (Araceae), commonly called Suran or Jimmikand, has high medicinal value and is used ethnomedicinally for the treatment of different gastrointestinal and inflammatory disorders.
OBJECTIVE: The present study evaluated the effects of extracts of Amorphophallus paeoniifolius tubers on acetic acid-induced ulcerative colitis (UC) in rats.
MATERIALS AND METHODS: Wistar rats were orally administered methanol extract (APME) or aqueous extract (APAE) (250 and 500 mg/kg) or standard drug, prednisolone (PRDS) (4 mg/kg) for 7 days. On 6th day of treatment, UC was induced by transrectal instillation of 4% acetic acid (AA) and after 48 h colitis was assessed by measuring colitis parameters, biochemical estimations and histology of colon.
RESULTS: APME or APAE pretreatment significantly (p
