The association between FABP7 serum levels with survival and neurological complications in acetaminophen-induced acute liver failure: a nested case–control study

Background: Acute liver failure (ALF) is characterized by acute derangement of liver function and carries high mortality. Viral hepatitis is still one of the main causes of ALF in the India as well in world. A prospective case control study was carried with the aim to determine the effect of N-acetylcysteine (NAC) on survival of viral-ALF patients.Methods: 37 patients with a diagnosis of viral-ALF were included in the study. 18 patients received NAC infusion for 72 hrs whereas 19 patients in control group received placebo. The variables evaluated were demographic, biochemical, outcome and length of hospital stay.Results: Out of 37 viral-ALF patients, acute HEV-induced ALF (48.6%) was most common followed by HBV (24.3%) and HAV (21.6%). The two groups were comparable for the various baseline characteristics (age, INR, bilirubin, ALT, creatinine, albumin, grade of encephalopathy, mean grade of coma etc.). Use of NAC was associated with a shorter length of hospital stay of survived patients (p=0.024). A total of 20 of 37 (54.1%) patients died with ALF complications; 7 (38.9%) patients belonged to NAC group and 13 (68.4%) patients to control group (p=0.079). HEV induced ALF showed significant improved in survival than Non HEV induced ALF with NAC administration (p=0.022).Conclusions: HEV was the most frequently cause of viral-ALF. Overall survival was not improved by NAC. HEV induced ALF showed significant improved in survival than Non HEV induced ALF with NAC administration. NAC reduced duration of hospital stay.

BACKGROUND: Adipokines are emerging mediators of immune response, and may affect susceptibility to active TB.OBJECTIVE: To examine the associations between adipokines and the risk of active TB.METHODS: In a case-control study nested within a prospective cohort of middle-aged and older adults in Singapore, 280 incident active TB cases who donated blood for research before diagnosis were matched with 280 controls. Serum levels of adiponectin, resistin, leptin and ghrelin were measured. Multivariable logistic regression models were used to compute the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between adipokines and the risk of active TB.RESULTS: Higher levels of leptin and resistin were associated with reduced risk of TB in a dose-dependent manner. Compared to those in the lowest quartile of leptin levels, those in the highest quartile had an OR of 0.46 (95%CI 0.26–0.82; P for trend = 0.009). Similarly, compared to those in the lowest quartile of resistin levels, those in the highest quartile had an OR of 0.46 (95%CI 0.24–0.90; P for trend = 0.03). Adiponectin and ghrelin levels were not associated with TB risk.CONCLUSION: Increased serum levels of leptin and resistin may be associated with reduced susceptibility to active TB infection.
