A Study of the Association between Diabetes Mellitus and Chronic Hepatitis B Virus Infection / Un Estudio de la Asociación entre la Diabetes Mellitus y la Infección Crónica por el Virus de la Hepatitis B

ABSTRACT Background: Hepatitis B virus (HBV) infection and diabetes mellitus are major health problems associated with significant morbidity and mortality. The published literature suggests an association of diabetes mellitus with liver disease. However, the role of HBV infection in diabetes aetiology is still controversial. The present study was conducted to explore the veracity of this enigmatic association among Pakistani subjects. Methodology: The blood samples and clinical information were collected from chronic HBV-positive patients Group 1 (n = 120), and their age and gender were matched with those of the healthy control subjects Group 2 (n = 120). Hepatitis B virus-positive patients were also subdivided into two groups; (Group 1a and Group 1b) with and without liver cirrhosis for evaluation of the prevalence of diabetes. Results: The study revealed that there were statistically significant differences in the biochemical parameters in the HBV-positive and control groups. There was no correlation between diabetes and HBV with the prevalence of diabetes mellitus being similar in subjects with and without HBsAg (11.7% in the positive group and 10% in the controls). Since there were a relatively large number (32.5%) of HBV-positive patients with liver cirrhosis, a comparison of biochemical parameters was also carried out to evaluate the extent of the liver damage and its association with diabetes. During the comparison of HBV patients with and without cirrhosis for the prevalence of diabetes, no aetiologic association was found with diabetes. Conclusion: Study revealed that there was no correlation between HBV infection and diaabetes despite the significantly different biochemical parameters in the HBV-infected group and control subjects.

RESUMEN Antecedentes: La infección por el virus de la hepatitis B (VHB) y la diabetes mellitus son problemas de salud importantes asociados con morbilidad y mortalidad significativas. La literatura publicada sugiere una asociación de la diabetes mellitus con las enfermedades hepáticas. Sin embargo, el papel de la infección por VHB en la etiología de diabetes sigue siendo contro-versial. El presente estudio fue conducido con el propósito de explorar la veracidad de esta enigmática asociación entre sujetos paquistaníes. Metodología: Se recogieron muestras de sangre e información clínica de pacientes crónicos VHB positivos Grupo 1 (n = 120), y su edad y género fueron comparados con los de los sujetos sanos del control Grupo 2 (n = 120). Los pacientes positivos al virus de la hepatitis B también se subdividieron en dos grupos, a saber, (Grupo 1a y Grupo 1b) con y sin cirrosis hepática en relación con la prevalencia de la diabetes. Resultados: El estudio reveló que hubo diferencias significativas en estos dos grupos en los parámetros bioquímicos entre el grupo de control y el grupo VHB positivo. En estos dos grupos no hubo correlación entre la diabetes y el VHB. Puesto que hubo un número relativamente grande (32.5%) de pacientes VHB positivos con cirrosis hepática, se realizó también una comparación de los parámetros bioquímicos a fin de comprender el grado del daño hepático y su asociación con la diabetes. Durante la comparación de los pacientes con VHB con y sin cirrosis en relación con la prevalencia de diabetes, no se halló asociación etiológica con la diabetes. Conclusión: Este estudio reveló que no hubo correlación entre la infección por VHB y la diabetes, a pesar de los parámetros bioquímicos significativamente diferentes entre el grupo infectado por el VHB y los sujetos del control.

Effect of gender, birth weight and gestational age on serum 17-hydroxyprogesterone concentration and distribution among neonates in Saudi Arabia.

Blood samples from 813 newborns were spotted on to filter paper and the 17-hydroxyprogesterone concentration was measured using the Delfia (R) fluorometric immunoassay. The median, mean, and standard deviation (SD) for the total population were 20, 21 and (11) nmol/L respectively. Males had significantly higher levels than females with median, mean and (SD) of 22, 22 and (12) nmol/L. Similarly, low birth weight babies were found to have significantly higher levels than normal birth weight babies with median, mean and (SD) of 21, 24 (12) nmol/L. Preterm babies were also found to have significantly higher levels than full term babies, with median, mean and (SD) of 25, 29 (16) nmol/L. As experienced elsewhere, those factors should be taken into consideration when considering a cut-off point in any neonatal screening program for congenital adrenal hyperplasia.
