Quality of life and hemoglobin levels of hemodialysis patient at Siriraj Hospital.

Objective: To evaluate the relationship of the quality of life (QOL), and hemoglobin (Hb) level of hemodialysis (HD) patients. Methods: This study was a cross-sectional study. Face-to-face interviews using a Kidney Disease Quality of Life - Short Form (KDQOL-SF™1.3) questionnaire (which consisted of SF-36 and kidney disease questionnaires) were conducted during November-December 2009 with 152 patients receiving hemodialysis at Siriraj hospital, Bangkok, Thailand. QOL measures were compared in stepwise Hb levels of 9, >9 to 10, >10 to 11, >11 to 12, and >12 g/dl. Scores of QOL and Hb level were examined for the relationship and statistical significance using ANOVA. Results: The increasing Hb levels are statistically significant increases in kidney disease domain scores on the kidney disease component of the questionnaire (p=0.042). About the SF36 component, the difference between 5 groups of Hb levels were significant in the general health (p=0.023), role emotion (p=0.015), social functioning (p=0.008), and mental component summary scores (p=0.039). Conclusion: The difference of the Hb levels were statistically significant differences in the effects of kidney disease, general health, role emotion, and social function scores, and mental component summary scores of the KDQOL-SF questionnaire. However, a long-term assessment should be considered. These findings have implications for the care of hemodialysis patients in terms of the initiation of the Hb target of erythropoietin (EPO) therapy.

An analysis of 3,555 cases of renal biopsy in Thailand.

BACKGROUND: The knowledge of the epidemiology of biopsied renal diseases provides useful information in clinical practice. There are several epidemiologic population-based studies of biopsy-proven nephropathies with detailed clinicopathologic correlations that could be different according to the country analyzed. OBJECTIVE: To identify the prevalence of primary and secondary glomerular diseases and to study the trend of the pattern changes of the glomerulopathy in Thailand. MATERIAL AND METHOD: A retrospective study of percutaneous renal biopsies during a 23-year period of 1982 to 2005 was performed. A total of 3,555 consecutive native kidney biopsies in adult patients between 12 and 84 years of age were analyzed for the prevalence and changes in the 5-year interval over the two decades. RESULTS: From the clinical trial of 3,275 patients, the ratio between primary and secondary glomerular diseases was 2:1 (2154:1121). The most common primary glomerular disease (2154 patients) were IgM nephropathy (n = 986, 45.8%) followed by IgA nephropathy (n = 386, 17.9%); membranous nephropathy (n = 341, 15.8%); diffuse endocapillary proliferative glomerulonephritis (n = 114, 5.3%) and diffuse crescentic glomerulonephritis (n = 71, 3.3%). Lupus nephritis was the most prevalent cause of secondary glomerulonephritis in the present study (n = 992, 88.5%). Examination of the 5-year interval along the study period revealed a significant increase in the prevalence of IgA nephropathy and diabetic nephropathy. Prevalence of focal and segmental glomerulosclerosis rose by five times over the last two decades in contrast to IgM nephropathy, which prevalence is decreasing. CONCLUSION: There is high prevalence of IgM nephropathy, IgA nephropathy, and lupus nephritis in Thailand which is different from other countries. It could be due to various races and altered environments. The information obtained from these results is an important contribution for the understanding of the prevalence in renal diseases in Thailand. It can be used as the baseline data for making efficient research into the appropriate and beneficial way of management in the future.

Effect of short-term folate and vitamin B supplementation on blood homocysteine level and carotid artery wall thickness in chronic hemodialysis patients.

OBJECTIVE: Hyperhomocysteinemia is an independent risk factor for atherosclerotic vascular disease in chronic hemodialysis patients. This stratified randomized controlled trial was designed to measure the effect of high dose oral vitamin B6, vitamin B12, and folic acid on homocysteine levels, and to evaluate the effect on atherosclerosis as measured by Intima-Media Thickness (IMT) of carotid arteries. MATERIAL AND METHOD: Fifty-four chronic hemodialysis patients with hyperhomocysteinemia were randomized to receive oral 15 mg folic acid, 50 mg vitamin B6, and 1 mg vitamin B12 daily (treatment group) or oral 5 mg folic acid alone (control group) for 6 months. Homocysteine level and IMT were measured in both groups. RESULTS: At 6 months, homocysteine levels in the treatment group were significantly reduced from 27.94 +/- 8.54 to 22.71 +/- 3.68 mmol/l (p = 0.009) and were not significantly increased from 26.81 +/- 7.10 to 30.82 +/- 8.76 mmol/l in control group (p = 0.08). Mean difference between both groups was statistically significant (p = 0.002). There was no significant difference of IMT of carotid arteries, however, a tendency that the treatment group would have less thickness was observed (0.69 +/- 0.29 mm and 0.62 +/- 0.16 mm, p = 0.99). CONCLUSION: Treatment of hyperhomocysteinemia in chronic hemodialysis patients with daily oral 15 mg folic acid, 50 mg vitamin B6, and 1 mg vitamin B12 for 6 months decreases homocysteine levels and tends to reduce IMT of carotid arteries. A long term study for the prevention of atherosclerosis is warranted.

Relationship between hyperhomocysteinemia and atherosclerosis in chronic hemodialysis patients.

BACKGROUND: Hyperhomocysteinemia is an independent risk factor of coronary artery heart disease (CAHD) and atherosclerosis in a normal population. However, it is still controversial in end-stage kidney disease patients who underwent long-term dialysis. Carotid intima-media thickness (IMT) is the standard non-invasive measurement of atherosclerosis. The aims of the present study were to determine the homocysteine (Hcy) level, and to evaluate its role as a risk factor of atherosclerosis in hemodialysis (HD) patients. MATERIAL AND METHOD: Clinical data and blood chemistries were assayed in 62 HD patients. Atherosclerosis was defined by clinical presentations of CAHD, cerebrovascular or peripheral vascular diseases, or carotid plaque by ultrasound. IMT was also measured by ultrasound RESULTS: Plasma Hcy level in HD patients was significantly higher in HD patients than normal controls (28.3 +/- 8.3 vs 9.7 +/- 2.9 micromol/l, p < 0.001). Older age (p < 0.001), male sex (p = 0.05), longer duration of HD (p = 0.05), and higher plasma Hcy level (p = 0.01) correlated with atherosclerosis by univariate analysis, but plasma Hcy did not show significant correlation by multivariable analysis. There was also correlation between IMT and atherosclerosis in HD patients (p < 0.001) but no correlation was observed between plasma Hcy level and lMT. CONCLUSION: Hyperhomocysteinemia is not an independent factor in the genesis of atherosclerosis in HD patients. Advanced age plays a major role of hyperhomocysteinemia and IMT is a useful marker of atherosclerosis in these patients.

Pregnancy complicated with SLE and RPGN : A case report.

Pregnancy complicated with systemic lupus erythematosus (SLE) is notoriously variable in its presentation, course, and outcome. Renal involvement is demonstrated in half of patients. Exaggerated by pregnancy on renal function is not concluded. But renal failure is one of the leading causes of death. We report a case of lupus complicating pregnancy that no prepregnancy remission. She developed clinically pre-eclampsia and lupus nephritis in 17 weeks gestation. Flares of disease with deterioration of renal function despite corticosteroid therapy lead to stop pregnancy. Although pregnancy has been terminated, she became worse and died before starting hemodialysis. Histologic study from renal necropsy and clinical manifestation consistented with rapidly progressive glomerulonephritis (RPGN).
