Objective: Secondary hemophagocytic lymphohistiocytosis (sHLH) is an increasingly recognized complication in patients with scrub typhus, potentially contributing to substantial mortality despite appropriate antibiotic treatment. This study aims to determine the prevalence and prognosis of sHLH and identify diagnostic factors in adult patients with scrub typhus in North India.

Methods: This prospective cohort study was conducted at PGIMER, Chandigarh, from August 2021 to November 2023. sHLH was defined as an HScore of 200 or above. The diagnostic performance of biomarkers such as ferritin, fibrinogen, triglycerides, and C-reactive protein was assessed through receiver operating characteristic curve analysis, evaluating area under the curve (AUC), sensitivity, and specificity.

Results: Out of 150 patients (mean age 39 years, 54% female), 28 (18.7%) were diagnosed with sHLH. Those presenting with high-grade fever, seizures, high pulse rate, hepatomegaly, splenomegaly, cytopenia, and significant hepatic dysfunction were more likely to have sHLH. Ferritin demonstrated the highest diagnostic utility (AUC 0.83), compared to fibrinogen (AUC 0.72), triglyceride (AUC 0.67), and C-reactive protein (AUC 0.69). The optimal cutoff for ferritin was 2000 ng/mL, with a sensitivity of 90% and a specificity of 66%. Higher ferritin thresholds (6000 ng/mL and 10000 ng/mL) increased specificity to 88% and 95%, respectively. Patients with sHLH often presented with multi-organ failure, necessitating mechanical ventilation and vasopressor support. In-hospital mortality was significantly higher in sHLH patients than in those without (21.4% vs 6.6%, p = 0.025).

Conclusion: Early detection of sHLH using the HScore and ferritin significantly influences the management of scrub typhus, underscoring the necessity for tailored therapeutic strategies to improve patient outcomes.

Background: Regional citrate anticoagulation (RCA) has emerged as a treatment modality that reduces bleeding risk and filter clotting. With initial experience of using RCA with continuous renal replacement therapy (CRRT), we have formulated a working protocol based on published literature.

Objective: The study aimed to evaluate the protocol for routine use of RCA during CRRT requiring anticoagulation and evaluation of filter life.

Methodology: It is a single-center, open-label, prospective, non-randomized, non-interventional, single-arm, observational study conducted at a tertiary care hospital between September 2022 and July 2023. All adult patients with acute kidney injury (AKI) or hyperammonemia requiring CRRT and necessitating the use of anticoagulation were enrolled in the study. The study used Prisma Flex M100 AN 69 dialyzer on Prisma Flex (Baxter) CRRT machines during continuous venovenous hemodiafiltration (CVVHDF). The targeted CRRT dose in all the study patients was 25-30 mL/kg/hour. Based on the published literature, we have developed a working protocol (Appendix 1) for managing patients on CRRT using RCA.

Results: A total of 159 patients were analyzed for the study. The median [interquartile range (IQR)] filter life using RCA was 30 (12-55) hours. Filter clotting was observed in 33.3% of patients. Citrate accumulation was present in 52.25% of patients, but no CRRT was discontinued as citrate accumulation resolved after following the corrective steps in the protocol. None of the patients had citrate toxicity. Chronic liver disease (CLD) (p ≤ 0.001) and those who were post-living donor liver transplant recipients (p = 0.004) had a statistically significant increase in citrate accumulation. Also, patients who had higher lactate at baseline (6 hours post-CRRT initiation), had a higher chance of citrate accumulation.

Conclusion: Our RCA protocol provides a safe approach to regional anticoagulation during CRRT in critically ill patients.

The terminology "Financially Palliative" is a pseudonym and refers to a unique challenge faced in countries where public healthcare insurance coverage is not robust and the percentage of out-of-pocket health expenditure continues to be high. Emergency and critical care healthcare expenditures in such circumstances usually pose additional burden as they are unforeseen expenses, disproportionately high, for which most people are unprepared. Such situations may lead into a vicious cycle that initiates with expenditure hesitancy and delay in definitive care, which in turn leads to deterioration in the patient's condition and delay-related complications. This further fuels expenditure hesitancy due to uncertain prognosis and outcomes. The future threats posed by this issue are manifold, which are not only restricted to poor patient outcomes and diminishing physician morale but also hinder progress in science by influencing research outcomes/endpoints in areas where it is highly prevalent. Identifying and defining the problem with terminology is only the first step in working towards solutions. The issue needs to be addressed and mitigated before it spreads its roots deeper into our healthcare system.

Background: Carbamazepine (CBX) is widely used for various medical conditions, but its associated toxicity poses significant clinical concerns. This study aims to provide insights into the clinical presentations, management strategies, and outcomes of CBX toxicity cases in an emergency department (ED) setting.

Methodology: This was a 10-year retrospective cohort chart review study, including all patients with elevated CBX levels. Data on clinical features, CBX levels, laboratory findings, electrocardiograms (ECGs), patient management, and outcomes were analyzed. Cases were categorized as acute or chronic toxicity.

Results: Out of the 1,965 medical charts reviewed, we included 70 patients with CBX levels above the therapeutic range (prevalence: 3.6%). Chronic CBX toxicity cases (55.7%) were predominant, with gastrointestinal (GI) symptoms being the most common. Most patients presented with isolated CBX overdoses (88.6%), while mixed overdoses (11.4%) were less frequent. Patients were categorized based on CBX levels: 44 had mild toxicity (>51 μmol/L), and 26 had moderate toxicity (>85 μmol/L). Within the mild group, 15 patients experienced acute toxicity, compared to 16 patients in the moderate group. Four patients who had mixed overdoses and low sensorium required intubation and mechanical ventilation. Three patients received activated charcoal (AC), and another 3 patients received multiple doses of AC to reduce drug absorption. The majority of patients (65.7%) required hospital admission, underscoring the seriousness of CBX toxicity. There were no fatalities among these 70 patients.

Conclusion: This study emphasizes the importance of a systematic approach to assessing and managing CBX toxicity, considering its diverse clinical presentations and variations in serum CBX levels.
