Background : Acute onset fever with altered mentation is a common problem encountered by the physician practicing in tropical countries. Central nervous system (CNS) infections are the most common cause resulting in fever with altered mentation in children. Aim : In this study, we have tried to analyze the cause of encephalopathy following short febrile illness in adults presenting to a tertiary care center in Northwestern part of India. Setting and Design : A prospective observational study carried out in a tertiary care center in the Northwestern India over a period of 1 year. Material and Methods : A total of 127 patients with fever of less than 2 weeks duration along with alteration in mentation were studied prospectively over a period of 12 months. The demographic variables were recorded in detail. In addition to routine investigations, cerebrospinal fluid analysis, noncontrast- and contrast-enhanced computed tomography, along with magnetic resonance imaging were performed in all the subjects. Statistical Analysis : The results were analyzed using SPSS statistical software. The values were expressed as mean with standard deviation for contiguous variable as percentage for the others. Results and Conclusion : Out of these, 70% had primary CNS infection as the etiology. A total of 33% patients had meningitis, 29.9% had evidence of meningoencephalitis, and 12.7% were diagnosed as sepsis-associated encephalopathy. These were followed by cerebral malaria, leptospirosis, and brain abscess as the cause of febrile encephalopathy in adults. Among the noninfectious causes, acute disseminated encephalomyelitis, cortical venous thrombosis, and neuroleptic malignant syndrome were documented in 2.36% each. In 11% of the patients, the final diagnosis could not be made in spite of the extensive investigations. Our study demonstrates that acute febrile encephalopathy in adults is a heterogeneous syndrome with primary CNS infections being the commonest etiology.

The syndrome of abnormal chromatin clumping is largely a morphological entity characterized by exaggerated chromatin clumping seen in the neutrophils. According to the recent World Health Organization (WHO) classification, it is categorized as a variant of atypical chronic myeloid leukemia (aCML) or Ph-negative CML. Most of the cases reported in literature have been negative for the Ph chromosome or the BCR-ABL gene. Till date, Ph positivity has been demonstrated in just one case. We report two more Ph-positive CML cases with abnormal chromatin clumping in neutrophils. To the best of our knowledge, this is only the second time in literature that such cases have been described. These two unusual cases go on to extend the morphological spectrum of granulocytic changes seen in Ph-positive CML.

For the detection of BCR-ABL1-like ALL cases, two methodologies, specifically Gene expression profiling (GEP) or Next-generation targeted sequencing (NGS) and TaqMan based low-density (TLDA) card, are being used. NGS is very costly and TLDA is not widely commercially available. In this study, we quantified the expression of 8 selected overexpressed genes in 536 B-ALL cases. We identified 26.67% (143/536) BCR-ABL1-like ALLs using hierarchical clustering and principal component analysis. BCR-ABL1-like ALL cases were significantly older at presentation (p = 0.036) and had male preponderance (p = 0.047) compared to BCR-ABL1-negative ALL cases. MRD-positivity and induction failure were more commonest in BCR-ABL1-like ALL cases (30.55 vs.19.35% in BCR-ABL1-negative ALL cases). Lastly, we built a PHi-RACE classifier (sensitivity = 95.2%, specificity= 83.7%, AUC= 0.927) using logistic regression to detect BCR-ABL1-like ALL cases promptly at diagnosis. This classifier is beneficial for hematologists in quick decision making at baseline to start tailored treatment regimes. [ABSTRACT FROM AUTHOR]
