METHODS: A Markov model of a Malaysian hypothetical cohort aged ≥30 years (N = 14,589,900) was used to estimate the total and per-member-per-month (PMPM) costs of RAS uptake. This involved an incidence and prevalence rate of 9.0% and 10.53% of patients with diabetes and hypertension respectively. Transition probabilities of health stages and costs were adapted from published data.
RESULTS: An increasing uptake of RAS drugs would incur a projected total treatment cost ranged from MYR 4.89 billion (PMPM of MYR 27.95) at Year 1 to MYR 16.26 billion (PMPM of MYR 92.89) at Year 5. This would represent a range of incremental costs between PMPM of MYR 0.20 at Year 1 and PMPM of MYR 1.62 at Year 5. Over the same period, the care costs showed a downward trend but drug acquisition costs were increasing. Sensitivity analyses showed the model was minimally affected by the changes in the input parameters.
CONCLUSION: Mild impact to the overall healthcare budget has been reported with an increased utilization of RAS. The long-term positive health consequences of RAS treatment would reduce the cost of care in preventing deterioration of kidney function, thus offsetting the rising costs of purchasing RAS drugs. Optimizing and increasing use of RAS drugs would be considered an affordable and rational strategy to reduce the overall healthcare costs in Malaysia.
OBJECTIVES: The objective of this review has been to evaluate the clinical effectiveness of available combined treatments modalities in the treatment of neovascular AMD.
DATA SOURCES: Central and Medline were searched for original research studies (Phase I, II, III), abstracts, and review articles concerning combination therapies for the control of neovascular AMD. We included randomized controlled trials (RCTs).
RESULTS: The results of therapeutic trials focused on the actual options in the management of neovascular AMD are discussed. Intravitreal treatment with substances targeting all isotypes of vascular endothelial growth factor (VEGF) results in a significant increase in visual acuity in patients with neovascular AMD. The combination with occlusive therapies like verteporfin photodynamic therapy (V-PDT) potentially offers a reduction of re-treatment frequency rate and long-term maintenance of the benefit reached. Despite the promise from combining anti-VEGF therapies with V-PDT, other combinations to improve outcomes with V-PDT deserve attention. Corticosteroids demonstrated an antiangiogenic effect and targeted the extravascular components of CNV, such as inflammatory cells and fibrocytes. Nevertheless, the study on the clinical application of corticosteroids will require a better understanding of the potential complications. Further developments interacting with various steps in the angiogenic cascade are under clinical or preclinical evaluation and may soon become available. In AMD the goal of a combination regimen is to address the therapy toward neovascular, inflammatory, and proliferative components of the disease.
CONCLUSIONS: Combined treatments strategies are an obvious step providing disease control when it is not achieved with a single therapeutic approach. One risk of using a single therapy to control AMD is a rebound induced by compensatory stimulation of other pathogenetic pathways. Combination therapy is a logical approach to address mechanisms of disease progression that appear to be self-sustaining once initiated.
METHODS: We conducted a retrospective review of childhood primary sclerosing cholangitis-inflammatory bowel disease from three tertiary centers in Singapore and Malaysia.
RESULTS: Of 24 patients (boys, 58%; median age at diagnosis: 6.3 years) with primary sclerosing cholangitis-inflammatory bowel disease (ulcerative colitis, n = 21; Crohn's disease, n = 1; undifferentiated, n = 2), 63% (n = 15) were diagnosed during follow-up for colitis, and 21% (n = 5) presented with acute or chronic hepatitis, 17% (n = 4) presented simultaneously. Disease phenotype of liver involvement showed 79% had sclerosing cholangitis-autoimmune hepatitis overlap, 54% large duct disease, and 46% small duct disease. All patients received immunosuppression therapy. At final review after a median [±S.D.] duration follow-up of 4.7 [±3.8] years, 12.5% patients had normal liver enzymes, 75% persistent disease, and 12.5% liver failure. The proportion of patients with liver cirrhosis increased from 13% at diagnosis to 29%; 21% had portal hypertension, and 17% had liver dysfunction. One patient required liver transplant. Transplant-free survival was 95%. For colitis, 95% had pancolitis, 27% rectal sparing, and 11% backwash ileitis at initial presentation. At final review, 67% patients had quiescent bowel disease with immunosuppression. One patient who had UC with pancolitis which was diagnosed at 3 years old developed colorectal cancer at 22 years of age. All patients survived.
CONCLUSIONS: Liver disease in primary sclerosing cholangitis-inflammatory bowel disease in Asian children has variable severity. With immunosuppression, two-thirds of patients have quiescent bowel disease but the majority have persistent cholangitis and progressive liver disease.
CASE PRESENTATION: We describe here three cases of type 2 diabetic patients that have rapid renal deterioration with rate of decline 46 - 60 mL/min per 1.73m2 per year. All the patients are heavily nephrotic. All of the renal biopsies done showed the classical diabetic changes, hypertensive changes, diffuse tubulointerstitial damage, and interstitial nephritis. All of the patients admitted to taking various form of traditional medications in hope of curing their renal disease.
CONCLUSION: We wish to highlight that type 2 diabetics with massive nephrotic range proteinuria have enhanced risk of rapid renal function deterioration. The patients should be educated about the risks of rapid renal function deterioration when there is presence of heavy proteinuria. High grade proteinuria is likely to inflict the diffuse tubulointerstitial inflammation. The interstitial nephritis could be further worsened by traditional supplements consumption. Timely health education and advice must be undertaken to retard this unwanted rapid renal disease progression.
AIM: Aging-associated CI can impair the ability of individuals to perform a VF test and compromise the reliability of the results. We evaluated the association between neurocognitive impairment and VF reliability indices in glaucoma patients.
METHODS: This prospective, cross-sectional study was conducted in the Ophthalmology Department, Hospital Kuala Pilah, Malaysia, and included 113 eyes of 60 glaucoma patients with no prior diagnosis of dementia. Patients were monitored with the Humphrey Visual Field Analyzer using a 30-2 SITA, standard protocol, and CI was assessed using the clock drawing test (CDT). The relationships between the CDT score, MD, pattern standard deviation, Visual Field Index (VFI), fixation loss (FL), false-positive values, and FN values were analyzed using the ordinal regression model.
RESULTS: Glaucoma patients older than 65 years had a higher prevalence of CI. There was a statistically significant correlation between CDT scores and glaucoma severity, FL, FN, and VFI values (rs=-0.20, P=0.03; rs=-0.20, P=0.04; rs=-0.28, P=0.003; rs=0.21, P=0.03, respectively). In a multivariate model adjusted for age and glaucoma severity, patients with lower FN were significantly less likely to have CI (odds ratio, 0.91; 95% confidence interval, 0.89-0.93) and patients with higher MD were more likely to have CI (odds ratio, 1.10; 95% confidence interval, 1.05-1.16); false positive, FL, pattern standard deviation, and VFI showed no significant correlation.
CONCLUSION: Cognitive decline is associated with reduced VF reliability, especially with higher FN rate and overestimated MD. Screening and monitoring of CI may be important in the assessment of VF progression in glaucoma patients.
