End-stage kidney disease has become an increasing burden in all regions of the world. However, limited epidemiologic data on chronic kidney disease in Southeast Asian populations are available. Therefore, a cohort study over a period of 12 yr (1985 to 1997) in 3499 employees of the Electric Generation Authority of Thailand, aged 35 to 55 yr, was conducted to determine the prevalence of decreased kidney function and risk factors associated with future development of decreased kidney function. The prevalence of decreased kidney function (GFR <60 ml/min) increased from 1.7% (95% confidence interval [CI], 1.3 to 2.1) in 1985 to 6.8% (95% CI, 5.7 to 7.9) in 1997, and the prevalence of elevated serum creatinine was 6.1% (95% CI, 5.3 to 6.9) and 16.9% (95% CI, 15.3 to 18.5) in 1985 and 1997 surveys, respectively. The adjusted odds ratio for future development of decreased kidney function was 2.57 (1.0 to 6.81) for systolic hypertension (>159 mmHg), 1.82 (1.12 to 2.98) for hyperuricemia (>6.29 mg/dl), 1.68 (1.02 to 2.77) for elevated body mass index (>24.9 kg/m 2 ) compared with subjects with systolic BP <140 mmHg, serum uric acid <4.5 mg/dl, and body mass index 20.8 to 22.8 kg/m 2 . The rising prevalence of decreased kidney function in this population resulted mainly from the increasing prevalence of the risk factors in the population. Screening to detect decreased kidney function and early intervention to modify the associated risk factors should be considered in otherwise healthy individuals. Future studies are also necessary to determine whether implementation of these measures results in a reduction of ESRD incidence in the population.
Thalassemia/hemoglobinopathy is a hereditary disease that causes chronic anemia and increased erythropoiesis. Consequently, an expansion of bone marrow spaces may contribute to osteopenia/osteoporosis. However, the pathogenesis of bone changes is not yet known. We, therefore, carried out the study on bone histomorphometry and biochemical and hormonal profiles in children and adolescents with suboptimally treated beta-thalassemia disease with the hope of gaining some new insight into the cellular and structural alterations of thalassemic bone. Seventeen patients underwent iliac crest bone biopsy for histomorphometric analyses. Bone mineral density (BMD) measurements were performed by dual energy x-ray absorptiometry. Most patients had growth retardation and delayed bone age. BMD was low especially at the lumbar spine. Serum IGF-I levels were almost always low. Bone histomorphometry revealed increased osteoid thickness, osteoid maturation time, and mineralization lag time, which indicate impaired bone matrix maturation and defective mineralization. In addition, iron deposits appeared along mineralization fronts and osteoid surfaces. Moreover, focal thickened osteoid seams were found together with focal iron deposits. Dynamic bone formation study revealed reduced bone formation rate. These findings indicate that delayed bone maturation and focal osteomalacia are the pathogenesis of bone disease in suboptimally blood-transfused thalassemics with iron overload. Iron deposits in bone and low circulating IGF-I levels may partly contribute to the above findings.
A prospective, open-label, randomized trial at Khon Kaen Hospital (Thailand) was conducted from July 2000 through December 2001 to compare the clinical efficacies of ceftriaxone and sodium penicillin G for the treatment of severe leptospirosis. A total of 173 patients with severe leptospirosis were randomly assigned to be treated with either intravenous ceftriaxone (1 g daily for 7 days; n=87) or intravenous sodium penicillin G (1.5 million U every 6 h for 7 days; n=86). The primary outcome was time to fever resolution. Survival analysis demonstrated that the median duration of fever was 3 days for both groups. Ten patients (5 in each group) died of leptospirosis infection. There were no statistically significant differences in the duration of organ dysfunction. Ceftriaxone and sodium penicillin G were equally effective for the treatment of severe leptospirosis. Once-daily administration and the extended spectrum of ceftriaxone against bacteria provide additional benefits over intravenous penicillin.
The presence of oliguria, hyperkalemia, pulmonary rales, or hypotension on admission in patients with leptospirosis indicated high risk of death. Intensive care and early intervention should be provided for patients who present with these risk factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
