RESUMEN
Introduction Chronic kidney disease (CKD) is known to cause an increase in fibroblast growth factor 23 (FGF23). Periodontitis, a condition recognized as a risk factor for CKD, is also potentially associated with the increment of FGF23. This study aims to compare FGF23 levels in CKD patients with and without periodontitis and non-CKD patients with and without periodontitis. Correlation with serum phosphate, calcium, and intact parathyroid hormone (iPTH) was assessed. Additionally, associations between FGF23, calcium, phosphate, iPTH, creatinine, urea, plaque score, and bleeding score with periodontitis in CKD patients were determined. Method A total of 124 participants were categorized into four groups: CKD patients with periodontitis (n=31), CKD patients without periodontitis (n=32), periodontitis patients without CKD (n=32), and healthy population (n=29). The selected CKD patients include those from stages 3 and 4 (predialysis) patients. Serum levels of FGF23, calcium, phosphate, iPTH, creatinine, and urea were analyzed. Oral examinations were conducted to determine the presence and absence of periodontitis and assess plaque and bleeding scores. Result A significantly higher level of FGF23 was found in CKD compared to non-CKD groups; however, no difference was observed with the presence of periodontitis in both CKD and non-CKD. There was no significant correlation found between FGF23 and serum calcium, phosphate, or iPTH concerning periodontal status. Apart from the bleeding score, there was no association between FGF23, calcium, phosphate, iPTH, creatinine, urea, and plaque score with the presence of periodontitis in CKD patients. Conclusion The presence of periodontitis was not associated with higher FGF23 levels in CKD patients. Changes in FGF23, calcium, phosphate, iPTH, creatinine, urea, and plaque score could not be attributed to the presence of periodontitis in CKD patients.
RESUMEN
BACKGROUND: Epidemiological studies regarding the correlation between anti-Müllerian hormone (AMH) and insulin resistance (IR) in polycystic ovarian syndrome (PCOS) remain inconsistent. The primary aim of this study was to determine the correlations between AMH and IR in patients with PCOS and to explore the selected factors that influence the correlations. METHODS: We conducted systemic searches of online databases (PubMed, Science Direct, Taylor and Francis, Scopus, and ProQuest) from inception to December 20, 2023 and manual searches of the associated bibliographies to identify relevant studies. We then performed subgroup and sensitivity analyses to explore the sources of heterogeneity, followed by a publication bias risk assessment of the included studies using the Joanna Briggs Institute critical appraisal tool. We used a random-effects model to estimate the pooled correlations between AMH and the homeostatic model assessment for insulin resistance (HOMA-IR) in patients with polycystic ovarian syndrome (PCOS). RESULTS: Of the 4835 articles identified, 22 eligible relevant studies from three regions were included and identified as low risk of bias. The random-effects pooled correlation estimate was 0.089 (95% confidence interval [CI]: -0.040, 0.215), with substantial heterogeneity (I2 = 87%; τ2 = 0.0475, p < .001). Subgroup analyses showed that the study region did not influence the correlation estimates, and sensitivity analysis showed no significant alteration in the pooled correlation estimate or 95% CI values. No publication bias was observed. CONCLUSION: There was a weak, statistically insignificant correlation between AMH and HOMA-IR in patients with PCOS. The correlation estimates did not vary according to the study participants' regions.

Chronic kidney disease (CKD) and chronic periodontitis (CP) contribute to the increased level of inflammatory biomarkers in the blood. This study hypothesized that successful periodontal treatment would reduce the level of inflammatory biomarkers in CKD patients. This prospective study recruited two groups of CP patients: 33 pre-dialysis CKD patients and 33 non-CKD patients. All patients underwent non-surgical periodontal therapy (NSPT). Their blood samples and periodontal parameters were taken before and after six weeks of NSPT. The serum level of high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), and periodontal parameters were compared between groups. On the other hand, kidney function indicators such as serum urea and estimated glomerular filtration rate (eGFR) were only measured in CKD patients. Clinical periodontal parameters and inflammatory markers levels at baseline were significantly higher (p < 0.05) in the CKD group than in the non-CKD group and showed significant reduction (p < 0.05) after six weeks of NSPT. CKD patients demonstrated a greater periodontitis severity and higher inflammatory burden than non-CKD patients. Additionally, CKD patients with CP showed a good response to NSPT. Therefore, CKD patients' periodontal health needs to be screened for early dental interventions and monitored accordingly.
RESUMEN
Thyroid hormones have a catabolic effect on bone homeostasis. Hence, this study aimed to evaluate serum vitamin D, calcium, and phosphate and bone marker levels and bone mineral density (BMD) among patients with different thyroid diseases. This cross-sectional study included patients with underlying thyroid diseases (n = 64, hyperthyroid; n = 53 euthyroid; n = 18, hypothyroid) and healthy controls (n = 64). BMD was assessed using z-score and left hip and lumbar bone density (g/cm2). The results showed that the mean serum vitamin D Levels of all groups was low (<50 nmol/L). Thyroid patients had higher serum vitamin D levels than healthy controls. All groups had normal serum calcium and phosphate levels. The carboxy terminal collagen crosslink and procollagen type I N-terminal propeptide levels were high in hyperthyroid patients and low in hypothyroid patients. The z-score for hip and spine did not significantly differ between thyroid patients and control groups. The hip bone density was remarkably low in the hyperthyroid group. In conclusion, this study showed no correlation between serum 25(OH)D levels and thyroid diseases. The bone markers showed a difference between thyroid groups with no significant difference in BMD.
RESUMEN
INTRODUCTION: Chronic kidney disease (CKD) is associated with periodontal disease due to its hyperinflammatory state. Limited studies have explored the prevalence of periodontal disease among CKD patients in Malaysia. OBJECTIVE: To assess the periodontal status of pre-dialysis CKD patients in Hospital Universiti Sains Malaysia. METHODS: A total of 46 pre-dialysis CKD patients who attended the nephrology clinic at Hospital Universiti Sains Malaysia were enrolled in this study. Periodontal examination was performed using the periodontal probing depth (PPD), clinical attachment loss (CAL) and plaque index. RESULTS: The majority of the CKD patients were Malay (95.7%) and 80.4% were males. The mean age of the patients was 58.5 years. Using PPD measurement, 37 (74.0%) of the patients had mild periodontitis, 9 (20.0%) had moderate periodontitis and 3 (6.0%) had no periodontitis. Based on CAL measurement, 12 (26%) patients had mild periodontitis, 29 (63.0%) had moderate periodontitis and 5 (11%) had severe periodontitis. The mean (standard deviation [SD]) value of mild and moderate-to-severe periodontitis by PPD measurement were 4.26 (0.26) and 5.24 (0.36), respectively. The mean of mild and moderate-to-severe periodontitis by CAL measurement were 2.66 (0.62) and 4.98 (0.73), respectively. There was no correlation between the periodontal parameters and estimated glomerular filtration rate (PPD: r = -0.160, P = 0.914; CAL: r = -0.135, P = 0.372; plaque index: r = 0.005, P = 0.974). CONCLUSION: This study revealed a greater prevalence and severity of chronic periodontitis among CKD patients. Thus, the periodontal health of CKD patients' needs to be screened and monitored.
