Comparative metabolome analysis reveals higher potential of haemoperfusion adsorption in providing favourable outcome in ACLF patients

BACKGROUND AND AIMS

Acute-on-chronic liver failure (ACLF) is a serious illness associated with altered metabolome, organ failure and high mortality. Need for therapies to improve the metabolic milieu and support liver regeneration are urgently needed.

METHODS

We investigated the ability of haemoperfusion adsorption (HA) and therapeutic plasma exchange (TPE) in improving the metabolic profile and survival in ACLF patients. Altogether, 45 ACLF patients were randomized into three groups: standard medical therapy (SMT), HA and TPE groups. Plasma metabolomics was performed at baseline, post-HA and TPE sessions on days 7 and 14 using high-resolution mass spectrometry.

RESULTS

The baseline clinical/metabolic profiles of study groups were comparable. We identified 477 metabolites. Of these, 256 metabolites were significantly altered post 7 days of HA therapy (p < .05, FC > 1.5) and significantly reduced metabolites linked to purine (12 metabolites), tryptophan (7 metabolites), primary bile acid (6 metabolites) and arginine-proline metabolism (6 metabolites) and microbial metabolism respectively (p < .05). Metabolites linked to taurine-hypotaurine and histidine metabolism were reduced and temporal increase in metabolites linked to phenylalanine and tryptophan metabolism was observed post-TPE therapy (p < .05). Finally, weighted metabolite correlation network analysis (WMCNA) along with inter/intragroup analysis confirmed significant reduction in inflammatory (tryptophan, arachidonic acid and bile acid metabolism) and secondary energy metabolic pathways post-HA therapy compared to TPE and SMT (p < .05). Higher baseline plasma level of 11-deoxycorticosterone (C03205; AUROC > 0.90, HR > 3.2) correlated with severity (r2 > 0.5, p < .05) and mortality (log-rank-p < .05). Notably, 51 of the 64 metabolite signatures (ACLF non-survivor) were reversed post-HA treatment compared to TPE and SMT(p < .05).

CONCLUSION

HA more potentially (~80%) improves plasma milieu compared to TPE and SMT. High baseline plasma 11-deoxycorticosterone level correlates with early mortality in ACLF patients.

Study of awareness of adrenal disorders among interns and postgraduate students of Hamidia Hospital, Bhopal

INTRODUCTION

Adrenal disorders could be a life-threatening emergency, hence requires immediate therapeutic management. For this awareness regarding its diagnosis, management, and treatment is prime important.

AIMS AND OBJECTIVE

To study the awareness of adrenal disorders among interns and postgraduates students of Hamidia Hospital, Bhopal.

MATERIALS AND METHODS

A cross-sectional questionnaire-based study was performed. Fifty-six participants, i.e., 1^st, 2^nd, and 3^rd years postgraduate residents of general medicine (n = 14 × 3) and interns (n = 14) were included in the study. There were 12 questions on adrenal insufficiency, adrenal adenoma, congenital adrenal hyperplasia (CAH), nonclassical CAH (NCCAH), pheochromocytoma, and Conn's syndrome. One mark was awarded for each correct response.

RESULTS

In the present study, 14 (25%) participants scored < 5 marks, 33 (58.9%) scored between 6 and 9, and 9 (16.1%) scored between 10 and 12. The mean score among the participants was 6.38 ± 2.505, with a range from 2 to 11 marks. The number of correct answers by postgraduates residents of 1^st year was 101, 2^nd year was 95, and 3^rd year was 93 and interns scored 68 out of total 168 questions in each group. Mean awareness score for residents of 1^st, 2^nd, 3^rd years participants and interns was 7.21 ± 2.806, 6.79 ± 2.119, and 6.64 ± 2.818 and 6.63 ± 2.505, respectively. Most of the participants recorded correct responses related to diagnosis (57.7%) followed by responses related to treatment (64.3%). Answers to a question regarding how commonly is adrenal insufficiency diagnosed in medical Intensive Care Unit, none of the individuals responded correctly.

CONCLUSION

There was a lack of awareness regarding diagnosis, management, and treatment of adrenal disorders in central India. We need to prioritize training related to these illnesses in our postgraduate teaching curriculum in practice.
