Comment to “Risk factors for serum alanine aminotransferase elevation: A cross-sectional study of healthy adult males in Tokyo, Japan”

Background: Hypothyroidism is associated with many biochemical abnormalities including increased serum alanine aminotransferase activity. Very few studies have been done regarding serum alanine aminotransferase activity in hypothyroid patients and, as far we know, no such study has been done in our populations. So, we designed this study in our population for evaluation of serum alanine aminotransferase activity in hypothyroid patients. The objective of this study was to assess serum alanine aminotransferase activity in hypothyroid patients and to find out relationship of alanine aminotransferase activity with severity of hypothyroidism. Methods: It was a retrospective cross sectional study to evaluate the serum alanine aminotransferase activity of hypothyroid patients and to find out relationship of alanine aminotransferase activity with severity of hypothyroidism and the values were compared with that of age and sex matched healthy euthyroid controls. Statistical analyses were performed by using SPSS for Windows version 12.0. Unpaired t test was done to find out any significant difference between the cases and controls with respect to age and serum alanine aminotransferase activity. Chisquare test was done to find out any significant difference between the cases and controls with respect to sex. Pearson correlation coefficient test was done to see the correlation of alanine aminotransferase activity with the severity of hypothyroidism. Results: Mean serum alanine aminotransferase activity was found significantly higher in hypothyroid patients compared to that of controls. Conclusion: Results of our study suggest that increased serum alanine aminotransferase activity is associated with hypothyroidism. Therefore, patients presenting with increased ALT activity with normal liver function tests are recommended to be investigated to explore hypothyroidism.

Abstract BackgroundSouth Africa has a persistent burden of sexually transmitted infections (STIs). Male circumcision has been shown to be effective in preventing HIV, and STIs but data are scarce on the protective effect of circumcision in high-risk populations such as migrant miners. The objective of this study was to assess the effect of medical and traditional circumcision on the prevalence of STIs after adjusting for other risk factors in Rustenburg, a mining town in North West Province, South Africa.MethodsThis cross-sectional study used baseline data collected from a cohort study. Adult males in a mining town were assessed for STIs (gonorrhea, chlamydia, and trichomoniasis) using syndromic assessment. Data on circumcision status and other risk factors for STIs were collected using an interviewer-administered questionnaire. Multivariable log binomial regression was used to assess the independent effect of circumcision on STI presence after adjusting for confounders.ResultsA total of 339 participants with a median age of 25 years (IQR 22-29) were included in the study, of whom 116 (34.2%) were circumcised. The overall STIs prevalence was 27.4% (95% CI 22.8% to 32.6%) and was lower in the circumcised participants compared with those who were uncircumcised (15.5% vs 33.6%, respectively, p<0.001). Both medical (OR 0.57, 95% CI 0.34-0.95, p = 0.030) and traditional circumcision (OR 0.34, 95% CI 0.13-0.86, p = 0.022) were strongly associated with a lower risk of STIs after adjustment for employment and condom use. ConclusionIn this high-risk population, with a relatively high prevalence of STIs, and where one third of males are circumcised, both medical and traditional circumcision appear to be protective against STIs.

Alt Activity

Abstract Background Numerous studies have consistently demonstrated that high body mass index (BMI) is related to elevated serum alanine aminotransferase (ALT) among adults, but little is known about the association regarding adolescents, especially in China. In this study, we aimed to investigate the association between BMI and ALT activity among Chinese adolescents. Methods A school-based cross-sectional study was performed among nine high schools in Shenzhen, China between February 2017 and June 2018. A generalized linear-regression model adjusting for age and gender was conducted, and bivariate correlation analysis between ALT and BMI was also performed. Results A total of 7,271 adolescents aged from 9 years to 17 years were enrolled. Height, weight, BMI, and ALT were higher among boys than among girls (all P < 0.001). The mean (standard deviation) of serum ALT levels was 14.26 (14.77) U/L. In the entire BMI range, the BMI−ALT correlation was stronger for boys (Spearman's r = 0.396, P < 0.001) and adolescents of 14 years−17 years (r = 0.356, P < 0.001) than for girls (r = 0.203, P < 0.001) and adolescents of 9 years−13 years (r = 0.221, P < 0.001), respectively. Serum ALT increased rapidly and followed a linear pattern from the point of BMI ≥20.5 kg/m2, and each increase of 1 kg/m2 in BMI range above 20.5 kg/m2 was averagely correlated with an increase of 2.71 U/L in ALT levels (P < 0.001). Conclusions We found a significant BMI−ALT relationship. BMI at 20.5 kg/m2 may be a cut-off for evaluating serum ALT. BMIs ≥27.1 kg/m2 for boys and ≥24.9 kg/m2 for girls were linked to an elevated ALT activity for Shenzhen adolescents.

Methods This cross-sectional study used baseline data collected from a cohort study. Adult males in a mining town were assessed for STIs (gonorrhea, chlamydia, and trichomoniasis) using syndromic assessment. Data on circumcision status and other risk factors for STI syndromes were collected using an interviewer-administered questionnaire. The following symptoms were assessed; penile discharge, painful urination, dyspareunia or penile sores. These symptoms indicate sexually transmitted infection in general since laboratory tests were not performed. Multivariable log binomial regression was used to assess the independent effect of circumcision on STI presence after adjusting for confounders. Results A total of 339 participants with a median age of 25 years (IQR 22–29) were included in the study, of whom 116 (34.2%) were circumcised.
