RESUMO
Background There is a high prevalence of left ventricular diastolic dysfunction (LVDD) in patients with type 2 diabetes mellitus (T2DM). The influencing factors of LVDD in T2DM are not fully understood. Objective This study aimed at assessing the prevalence of LVDD in T2DM as well as looking at the association between various parameters related to T2DM with LVDD in patients with T2DM. Materials and methods This was a single-centre cross-sectional study in Kerala, India. The primary objective of the study was to assess the prevalence of LVDD in T2DM. The secondary objectives were to look for an association between higher glycated haemoglobin (HbA1c), complications of T2DM, age, and gender of the patient with the presence of LVDD. Results A total of 80 patients were included in the study. There were 40 patients with LVDD with a prevalence of 50%. There was a statistically significant positive association between increased age, longer duration of diabetes, higher HbA1C, the presence of diabetic neuropathy, diabetic retinopathy, and diabetic nephropathy with the prevalence of LVDD. A logistic regression analysis demonstrated that the presence of diabetic retinopathy is a risk factor for LVDD in the study subjects.
RESUMO
Objective The main aim of this study is to understand the existing knowledge gap between thyroid function tests and the severity of liver cirrhosis as measured by the Child-Pugh score. Materials and methods This is a cross-sectional study conducted on 100 patients diagnosed with cirrhosis of liver. Serum triiodothyronine (free T3), thyroxine (free T4), and thyroid stimulating hormone (TSH) levels were measured, and the severity of liver cirrhosis was measured by Child-Pugh score and statistical analysis were done to investigate the association of free T3, free T4 and TSH levels with Child-A, Child-B, and Child-C severity groups. Results The results revealed that there is a statistically significant positive correlation between TSH levels and Child-Pugh score, whereas a statistically significant negative correlation was associated between free T3 (fT3), free T4 (fT4) levels, and Child-Pugh Score. Further, we also observed that the Child-C group has 7.5-fold risk of increased TSH levels (odds ratio {OR} = 7.553, 95% CI = 2.869-19.883, p = 0.000), has 5-fold risk of decreased fT3 levels (OR = 5.023, 95% CI = 1.369-18.431, p = 0.009) and has 6.4-fold risk of decreased fT4 levels (OR = 6.402, 95% CI = 2.516-16.290, p = 0.000). Conclusion Our results demonstrated that there is a positive and direct correlation associated between increasing TSH with severity of liver cirrhosis as measured by Child-Pugh score, whereas a negative and inverse correlation was observed between decreasing fT3 and fT4 levels with the severity of liver cirrhosis as measured by Child-Pugh score. This suggests that the Child-Pugh score can be used as a prognostic indicator in cirrhotic patients.
