Severe Acute Liver Injury: First Manifestation of Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a common multisystem disease characterised by a wide variety of presentation patterns and complex manifestations. As a lymphoid organ, the liver plays an important role in the immune response and is a target of autoimmune responses.1 SLE can affect the liver in approximately 25-60 % of patients during their disease course.2,3 Liver dysfunction and SLE can present with complicated differential diagnoses. Liver dysfunction in SLE is usually mild and rarely leads to advanced liver diseases such as cirrhosis and liver failure.4,5 Liver dysfunction in SLE is usually caused by non-SLE-related causes such as drug toxicity, fatty liver, alcoholism, and associated autoimmune hepatitis. However, primary liver involvement in SLE is also well-recognised. Patients with SLE who present with acute liver failure are rare. We report a rare case of SLE-associated acute severe liver injury along with a literature review.

Enhanced Liver Fibrosis Score: Is It Useful for Evaluation of Fibrosis Severity in Chronic Hepatitis C Infection?

INTRODUCTION: The assessment of liver fibrosis is important in patients with chronic hepatitis C (CHC). In recent years, non-invasive tests like enhanced liver fibrosis (ELF) have been developed as an alternative to liver biopsy for estimating the severity of liver fibrosis. Therefore, we aimed to assess whether the ELF score can be used for fibrosis severity estimation using liver biopsy as the gold standard. MATERIALS AND METHODS: Forty-nine patients with CHC were enrolled in this study. Liver biopsy, ELF assessment, and transient elastography (TE) were performed in all patients, and severity of fibrosis on histopathology was assessed by meta-analysis of histological data in viral hepatitis (METAVIR) score. In addition, the diagnostic performance of ELF was evaluated by receiver operator characteristic curve (ROC) analyses, and liver biopsy histopathology was taken as the gold standard for the severity of liver fibrosis. RESULTS: The area under receiver operator characteristic curve (AUROC) for significant fibrosis of ELF score was 0.64 (95% confidence interval {CI}, 0.48-0.79) and of TE was 0.85 (95% CI, 0.73-0.96). The AUROC for advance fibrosis of ELF was 0.77 (95% CI, 0.57-0.97) and TE was 0.98 (95% CI, 0.94-1.0). The calculated cut-offs of ELF overestimated fibrosis in 53.06% (26/49) of patients and underestimated fibrosis in 6.12% (3/49) patients. AUROC of TE was significantly better than ELF for diagnosis of significant fibrosis (p=0.004) and advanced fibrosis (p=0.034). CONCLUSION: The ELF score can be used for estimating the severity of fibrosis but it is inferior to TE in estimating liver fibrosis severity.

Risk factors of multidrug-resistant bacterial infections among patients admitted in a tertiary care hospital of north India.

INTRODUCTION: Infections with drug-resistant organisms (DRO) have been associated with poor patient outcomes. To tackle this global problem, it is necessary to understand the risk factors that predispose to infections with DRO. METHODOLOGY: This was a prospective observational study conducted over a three-year period at a tertiary-care hospital. Bacterial culture isolates from patients admitted in medicine wards with community or hospital-acquired infections were included. Logistic regression analysis was used to determine risk factors for drug-resistant infections. RESULTS: Of the 295 patients with 323 isolates included, 40 (12.3%) had non-MDR (N-MDR) infections, 86 (26.6 %) had MDR infections and 197 (61%) had possible extensively drug-resistant (P-XDR) infections. History of previous admission in the preceding three months (Odds Ratio, OR = 4.53, 95% Confidence interval, CI = 1.8 - 11.42, p = -0.01), high SOFA score at admission (OR = 1.14, 95% CI = 1.0 - 1.290, p = -0.039) and prolonged duration of ventilation (OR = 1.25, 95% CI = 1.05 - 1.41, p = -0.012) were independently associated P-XDR infections when compared to patients with N-MDR. CONCLUSIONS: High rate of multidrug-resistant infections in the studied area is alarming. In this single-centre study, we elicited various risk factors for drug-resistant bacterial infections ranging from patient characteristics to iatrogenic risk factors during the hospital stay. Infections with P-XDR and MDR isolates independently increased hospital and ICU stay duration and were associated with increased mortality.

Antimicrobial Resistance Patterns in Clinically Significant Isolates from Medical Wards of a Tertiary Care Hospital in North India.

Background The global burden of infections due to multidrug-resistant organism (MDRO) has a significant impact on patients' morbidity and mortality along with increased healthcare expenditure. Aim This article estimates the prevalence of MDRO and the spectrum of clinical infectious syndromes caused by these organisms in medical wards of a tertiary care hospital in India. Design and Methods A cross-sectional observational study was performed among patients admitted in medicine wards diagnosed with the various infectious syndromes and one or more clinically significant positive culture at a tertiary care hospital in North India over a period of 18 months. Results Out of 323 clinically significant microbiological culture isolates from 229 patients included in the study, 86 (27%) isolates showed multidrug resistance (MDR) pattern, 197 (61%) isolates showed possible extremely drug-resistance pattern, and only 40 (12%) isolates showed nonmultidrug-resistance pattern of antibiogram. Conclusion The prevalence of MRDOs is high in clinically significant culture isolates from medicine wards in India. This emphasizes the importance of appropriate antibiotic usage and implementation of antibiotic stewardship programs in this part of the world.

Metronidazole induced encephalopathy: A rare side effect with a common drug.

In hospitals, seizures and encephalopathy are one of the common complications observed in critically ill patients. Drug intoxication, metabolic derangements, and anatomical abnormalities can cause altered mental status. We encountered an uncommon case with a diagnostic dilemma due to persistent encephalopathy, where metronidazole toxicity was an etiological factor. A 45-year-old male, who was admitted with the diagnosis of ruptured amoebic liver abscess. During the course of his management, he developed seizures and altered sensorium. After excluding other etiologies for in-hospital de novo seizure, a suspicion of metronidazole toxicity was considered. MRI brain was done which suggested the same. Metronidazole induced encephalopathy (MIE) is an uncommon adverse effect of treatment with metronidazole. Diagnosis is made by identifying specific radiological findings. It characteristically affects the cerebellum and subcortical structures. While the clinical and neuroimaging changes are usually reversible, persistent encephalopathy with poor outcomes may occur as seen in our case.
