Health-care-seeking behaviour in patients with hypertension: experience from a dedicated hypertension centre in Bangladesh.

Objective: The study aimed to assess health-seeking behaviour (HSB) and associated factors among hypertensive patients in Bangladesh.Methods: This cross-sectional study was conducted in the Hypertension & Research Centre, Rangpur, Bangladesh, between January 2022 and June 2022. A total of 497 hypertensive adults were recruited consecutively. A pre-tested structured questionnaire was deployed by the research team for data collection. Multivariable logistic regression analysis was used to explore the predictors of HSB.Results: The mean age of the hypertensive patients was 52 ± 11 (SD) years. Most of them were aged between 51 and 60 years (33%), female (55%), came from rural areas (57%), and belonged to middle socioeconomic class (68%). One-fourth of the patients (27%) had chosen informal healthcare providers for their first consultation. Fear of stroke (244, 45%), headache (170, 36%), and neck pain (81, 17%) were the three most common compelling causes of their visit to the hypertension centre. Age (aOR 0.78, 95% CI 0.68 - 0.89), male sex (aOR: 1.79, 95% CI 1.05 - 3.10), living in semi-urban (aOR 4.68, 95% CI 1.45 - 15.10) and rural area (aOR 1.68, 95% CI 1.01 - 2.80), farmers as occupation (aOR: 3.24, 95%CI: 1.31 - 8.06) and belonging to lower social economic class (aOR 4.24, 95% CI 1.68 - 10.69) were predictors of visiting informal providers of hypertensive patient. One-fourth of the hypertensive patients received consultation from informal healthcare providers.Conclusions: Raising awareness among patients and proper referral to specialised hypertension centres could promulgate the patients towards appropriate behaviour.

Effect of probiotics supplementation on liver stiffness and steatosis in patients with NAFLD.

Background and Aim: To compare the effects of probiotics on liver stiffness and steatosis in obese and non-obese patients with nonalcoholic fatty liver disease (NAFLD),the pragmatic clinical trial included 50 obese body mass index (BMI) ≥25 kg/m2 and 50 non-obese NAFLD BMI <25 kg/m2 age and sex-matched patients. Materials and Methods: Fibroscan with controlled attenuated parameter (CAP) was done at day 0 and at the end of 6 months. Probiotics supplementation was provided for both groups for 6 months along with lifestyle modifications. Results: At inclusion, both groups had comparable characteristics except BMI, metabolic syndrome and waist circumference (WC). Beneficial changes occurred in BMI (p=0.024), WC (p=0.045), ALT (p=0.024), total cholesterol (p=0.016), LDL (p=0.025) and triglyceride (p=0.021) of obese group, systolic blood pressure (p=0.003) and LDL level (p=0.018) in non-obese group. No significant change was observed in liver enzymes and glycemic profiles. Significant improvement in CAP was observed in both groups. But after adjusting for changes in BMI and WC, the change in CAP among non-obese participants were significantly higher compared to obese, mean change of 19.33±48.87 and 16.02±51.58 dB/m in non-obese and obese patients, respectively; p=0.044). Conclusion: Probiotics improve CAP/ steatosis in both obese and non-obese NAFLD patients and improvement was higher in non-obese, irrespective of BMI change.

Effect of Weight Reduction on Histological Activity and Fibrosis of Lean Nonalcoholic Steatohepatitis Patient.

BACKGROUND AND OBJECTIVES: Weight reduction has evidenced benefit on attenuation of histological activity and fibrosis of nonalcoholic steatohepatitis (NASH), but there is scarcity of data for lean NASH subgroup. We have designed this study to compare the effects of weight reduction on histological activity and fibrosis of lean and non-lean NASH. METHODS: We have included 20 lean and 20 non-lean histologically proven NASH patients. BMI < 25 kg/m2 was defined as non-lean. Informed consent was taken from each subject. All methods were carried out in accordance with the Declaration of Helsinki. Moderate exercise along with dietary restriction was advised for both groups for weight reduction. After 1 year, 16 non-lean and 15 lean had completed second liver biopsy. RESULTS: Age, sex, alanine transaminase (ALT), aspartate aminotransferase (AST), gamma-glutamyltrasferase (GGT), Homeostasis model assessment insulin resistance (HOMA-IR), triglyceride and high density lipoprotein (HDL) was similar in both groups. Steatosis, ballooning, lobular inflammation, nonalcoholic fatty liver disease activity score (NAS) and fibrosis was similar in the two groups. In lean/non-lean group, any amount of weight reduction, ≥ 5% weight reduction and ≥ 7% weight reduction was found in respectively 8/11, 5/6 and 2/6 patients. In both lean and non-lean groups, weight reduction of any amount was associated with significant reduction of steatosis, ballooning and NAS, except lobular inflammation and fibrosis. In both groups, weight reduction of ≥ 5% was associated with significant reduction in NAS only. However, significant improvement in NAS was noted with ≥ 7% weight reduction in non-lean group only. CONCLUSION: Smaller amount of weight reduction had the good benefit of improvement in all the segments of histological activity in both lean and non-lean NASH.

Effect of Pentoxifylline on Histological Activity and Fibrosis of Nonalcoholic Steatohepatitis Patients: A One Year Randomized Control Trial.

BACKGROUND AND OBJECTIVES: To observe the effect of Pentoxifylline for 1 year on hepatic histological activity and fibrosis of nonalcoholic steatohepatitis (NASH). MATERIALS AND METHODS: A single center, open label Randomized Control Trial. Patients were included if they had ultrasonographic evidence of fatty liver and nonalcoholic fatty liver disease activity score (NAS) ≥ 5 on liver histology. A total of 35 patients were selected; 25 of PL (Experimental) group and 10 of L (Control) group. PL group received 400 mg pentoxifylline thrice daily along with lifestyle modification and there was only lifestyle modification for the L group. After one year, NAS and fibrosis was compared in both groups. RESULTS: In PL group, NAS improved 2.10 ± 1.07; whereas in L group, NAS was 0.90 ± 0.99 (P = 0.006). As per the protocol analysis, NAS ≥ 2 improved in 15/20 (75%) in PL group and in 3/10 (30%) in L group (P = 0.018). In PL group, the individual component of NAS, steatosis improved from 2.30 ± 0.66 to 0.95 ± 0.76 (P = 0.000), lobular inflammation from 1.65 ± 0.59 to 1.05 ± 0.51 (P = 0.002) and hepatocyte ballooning from 1.50 ± 0.51 to 1.30 ± 0.57 (P = 0.258). In L group, steatosis improved from 2.30 ± 0.68 to 1.40 ± 1.08 (P = 0.01), lobular inflammation and hepatocyte ballooning did not improve. The fibrosis score did not improve in any group. In PL group, NAS improved significantly (P = 0.027; OR=22.76, CI=1.43-362.40) independent of weight reduction. CONCLUSION: Pentoxifylline for 1 year improves the hepatic histological activity but not fibrosis of NASH patients.

Insulin resistance in development and progression of nonalcoholic fatty liver disease.

Although insulin resistance (IR) is strongly associated with nonalcoholic fatty liver disease (NAFLD), the association of IR and NAFLD is not universal and correlation between IR and severity of NAFLD is still controversial. In this review, we summarize recent evidence that partially dissociates insulin resistance from NAFLD. It has also been reported that single-nucleotide polymorphisms in the diacylglycerol acyltransferase gene, rather than IR, account for the variability in liver fat content. Polymorphisms of the patatin-like phospholipase 3 gene have also been reported to be associated with NAFLD without metabolic syndrome, which suggests that genetic conditions that promote the development of fatty changes in the liver may occur independently of IR. Moreover, environmental factors such as nutrition and physical activity as well as small intestinal bacterial overgrowth have been linked to the pathogenesis of NAFLD, although some of the data are conflicting. Therefore, findings from both genetically engineered animal models and humans with genetic conditions, as well as recent studies that have explored the role of environmental factors, have confirmed the view that NAFLD is a polygenic disease process caused by both genetic and environmental factors. Therefore, IR is not the sole predictor of the pathogenesis of NAFLD.

Nonalcoholic steatohepatitis in nonalcoholic fatty liver disease patients of Bangladesh.

AIM: To explore the prevalence and risk factors for nonalcoholic steatohepatitis (NASH) in nonalcoholic fatty liver disease (NAFLD) patients. METHODS: We have included 493 patients with sonographic evidence of a fatty change, and 177 of these individuals were evaluated and confirmed after liver biopsy. The exclusion criteria consisted of significant alcohol abuse (< 20 g daily), evidence of hepatitis B and C, evidence of drug-induced fatty liver disease and other specific liver diseases such as hemochromatosis, Wilson's disease or autoimmune liver disease. The patients were assessed for metabolic syndrome, and biochemical, anthropometric and histopathological evaluations were carried out. The degree of disease activity in the NAFLD patients was evaluated using the NAFLD Activity Score. The data were analyzed by SPSS, version 16.0. RESULTS: Females predominated among the study participants (250, 57.0%), and the mean age was 40.8 ± 10.2 years. The numbers of overweight, obese I and obese II patients were 58 (13.2%), 237 (53.9%) and 93 (21.2%), respectively. However, there were 422 (96.2%) centrally obese patients. NASH was absent in 10 (5.6%) cases, borderline in 92 (52.6%) cases and present in 75 (42.4%) cases. The presence of diabetes could significantly (P = 0.001) differentiate NASH from simple steatosis. The following parameters did not influence the development of NASH: age, sex, basal metabolic index, waist circumference, serum high-density lipoprotein, triglyceride, insulin resistance index, hypertension and metabolic syndrome. The serum gamma-glutamyl transpeptidase (GGT) level was significantly higher (P = 0.05, 51.7 ± 32.8 and 40.4 ± 22.6 U/L) in the NASH patients, with a sensitivity of 45% and a specificity of only 68%. The serum alanine aminotransferase and aspartate aminotransferase levels were not able to predict NASH. CONCLUSION: Females were the predominant sufferers of NAFLD in Bangladesh. The prevalence of NASH was high. Diabetes was found to be the main culprit in developing NASH. GGT was the only biochemical marker of NASH. We recommend liver biopsy in NAFLD patients who have diabetes and elevated GGT.
