The Etiology of Advanced Chronic Kidney Disease in Southeast Asia: A Meta-analysis.

INTRODUCTION: Chronic kidney disease (CKD) etiology varies greatly between developed and developing countries. In addition, differences in underlying pathogenesis and therapeutic options affect the progression towards advanced-CKD. This meta-analysis aims to identify the etiology of advanced-CKD in Southeast Asia. METHODS: A systematic search in four electronic-databases and complementary search on national kidney registries and repository libraries was conducted until July 20, 2023. The risk of bias was assessed using Newcastle-Ottawa Scale for observational studies and Version-2 of Cochrane for intervention studies. A random-effects model was used to estimate pooled prevalence. The protocol is registered in the International Prospective Register of Systematic Reviews PROSPERO; Registration ID:CRD42022300786. RESULTS: We analyzed 81 studies involving 32,834 subjects. The pooled prevalence of advanced-CKD etiologies are diabetic kidney disease (DKD) 29.2% (95%CI 23.88-34.78), glomerulonephritis 20.0% (95%CI 16.84-23.38), hypertension 16.8% (95%CI 14.05-19.70), other 8.6% (95%CI 6.97-10.47), unknown 7.5% (95%CI 4.32-11.50), and polycystic kidney disease 0.7% (95%CI 0.40-1.16). We found a significant increase in DKD prevalence from 21% (9.2%, 95%CI 0.00-33.01) to 30% (95%CI 24.59-35.97) before and after the year 2000. Among upper-middle-income and high-income countries, DKD is the most prevalent (26.8%, 95%CI 21.42-32.60 and 38.9%, 95%CI 29.33-48.79, respectively), while glomerulonephritis is common in lower-middle-income countries (33.8%, 95%CI 15.62-54.81). CONCLUSION: The leading cause of advanced-CKD in Southeast Asia is DKD, with a substantial proportion of glomerulonephritis. An efficient screening program targeting high-risk populations (diabetes mellitus and glomerulonephritis) is needed, with the aim to delay CKD progression.

The relationship of diabetes, periodontitis and cardiovascular disease.

Cardiovascular complications in diabetic patients comprise of interaction between traditional and non-traditional risk factors. This interaction is thought to play role in four-times increment of cardiovascular mortality risk in diabetic patients, compared to non-diabetics. Chronic inflammation is known to be one of atherosclerosis non-traditional risk factor and has a role on every phase of atherogenesis. Periodontitis is the most common cause of chronic inflammation in diabetic patient. Both periodontitis and diabetes have detrimental effect on each other in terms of alveolar bone destruction and poor metabolic control, by continuous inflammatory mediator activation. Defect of bacteria elimination ability and monocyte hyper-responsiveness in diabetic patients leads to persistent elevation of systemic inflammatory mediators. This process give rise to prolonged and augmented exposure to inflammatory cytokines. This exposure interacts with traditional risk factor could lead to initiation of endothelial dysfunction, the first phase of atherogenesis.

Gastroschisis Following Treatment with High-Dose Methimazole in Pregnancy: A Case Report.

Hyperthyroidism in pregnancy is associated with a increased incidence of low birth weight, preterm birth and admission to the neonatal intensive care unit. However, available treatment options are limited. In this report, we present a case of fetal gastroschisis with a history of intrauterine exposure to methimazole. A 37-year-old woman was diagnosed with Grave's disease 3 years before her pregnancy. She had a poor response to propylthiouracil and required high-dose methimazole before her pregnancy. During the first trimester, she received methimazole 120 mg/day. After her 12th week of pregnancy, she received block-and-replace therapy (levothyroxine [LT4] 50 µg/day) because of the risk of hypothyroidism, and the dose of methimazole was downtitrated to 60 mg/day. Fetal ultrasonography showed fetal growth retardation and gastroschisis at gestational week 33. The relationship between the very high doses of methimazole in the first trimester of pregnancy and the incidence of gastroschisis in this patient was not fully understood because evidence of a relationship between the use of antithyroid drugs in the first trimester and congenital abnormalities in the fetus is lacking. Furthermore block-and-replace therapy is not recommended in pregnancy because it requires a higher dose of methimazole. We recommend preconception counseling and early screening of thyroid function. The counseling should include the best timeline for pregnancy and a discussion of the risks and benefits of hyperthyroidism treatment options.

Association of Periodontitis and Arterial Stiffness in Type 2 Diabetic Patients.

BACKGROUND: periodontitis is a major cause of chronic infection in diabetic patients. Diabetic patients have four-fold risk of having cardiovascular disease. Chronic inflammation caused by periodontitis, a non-traditional cardiovascular risk factor is widely known to play a major role in atherogenesis. Among non-diabetics, an association has been found between periodontitis and arterial stiffness, but in diabetic patients the result is inconsistent. No study has investigated either the proportion of periodontitis or its correlation with arterial stiffness in type 2 diabetes population in Indonesia. METHODS: this study was a cross-sectional study involving 97 patients with type 2 diabetics, who were recruited on Endocrinology Clinic from April to August 2017. Periodontitis was measured for pocket depth, clinical attachment loss and bleeding on probing by a periodontist. Carotid-femoral PWV (Pulse Wave Velocity) was measured using SphygmoCor Xcel with cuff-based tonometry technique. RESULTS: periodontitis was found in 99% type 2 diabetic subjects and 78% of them had severe periodontitis. There was no significant correlation found between pocket depth, clinical attachment loss and cfPWV (r=0.024, p=0.407 and r=0.011, p=0.456); whereas there was a weak positive correlation between pocket depth and PWV (r=0.294, p=0.041) in well-controlled type 2 diabetics. CONCLUSION: most of type-2 diabetics had severe periodontitis; however, the correlation between periodontitis and arterial stiffness could not be concluded in this study.
