Abstract
Impaired function of hematopoiesis after treatment with chimeric antigen T-cells (CAR-T) is a frequent finding and can interest a wide range of patients, regardless of age and underlying disease. Trilinear cytopenias, as well as hypogammaglobulinemia, B-cell aplasia, and T-cell impairment, can severely affect the infectious risk of CAR-T recipients, as well as their quality of life. In this review, we provide an overview of defects in hematopoiesis after CAR-T, starting with a summary of different definitions and thresholds. We then move to summarize the main pathogenetic mechanisms of cytopenias, and we offer insight into cytomorphological aspects, the role of clonal hematopoiesis, and the risk of secondary myeloid malignancies. Subsequently, we expose the major findings and reports on T-cell and B-cell quantitative and functional impairment after CAR-T. Finally, we provide an overview of current recommendations and leading experiences regarding the management of cytopenias and defective B- and T-cell function.

Abstract
Leishmaniasis is a zoonotic disease in humans caused by the bite of a parasite-infected sandfly. The disease, widely referred to as "poor man's disease," affects millions of people worldwide. The clinical manifestation of the disease depends upon the species of the parasite and ranges from physical disfigurement to death if left untreated. Here, we review the past, present, and future of leishmaniasis in detail. The life cycle of Leishmania sp., along with its epidemiology, is discussed, and in addition, the line of therapeutics available for treatment currently is examined. The current status of the disease is critically evaluated, keeping emerging threats like human immunodeficiency virus (HIV) coinfection and post kala-azar dermal leishmaniasis (PKDL) into consideration. In summary, the review proposes a dire need for new therapeutics and reassessment of the measures and policies concerning emerging threats. New strategies are essential to achieve the goal of leishmaniasis eradication in the next few decades.

Abstract
Background: Pancytopenia, an important hematological presentation is associated with different causes, which may vary in different regions. Uttarakhand, a north Himalayan state of India lacks studies of pancytopenia and the prevalent causes present in this region. Therefore, the present study was conducted to study the clinico-hematological profile of pancytopenia in a tertiary care center in the Uttarakhand, a north Himalayan state of India. It was also intended to study if these causes showed any variation from other studies done in different regions of India. Materials and Methods: The present observational study was conducted in a tertiary care institute situated in Uttarakhand state of India over a period of 1 year and 8 month from June 2017 to Feb 2019 including all the cases of pancytopenia. Results: The most common cause of pancytopenia was megaloblastic anemia (25%), followed by aleukemic leukemia and hypoplastic/aplastic anemia (19.1% each). Visceral leishmaniasis also constituted an important cause of pancytopenia in this study (11.7%). Conclusion: The study concludes that megaloblastic anemia and aleukemic leukemia are the most common cause of pancytopenia. Although leishmaniasis is considered to be non-endemic in this region, it constitutes an important cause of pancytopenia here. The clinicians, especially the physicians practicing the primary care and pathologists, should be aware of the different causes of pancytopenia present in this Himalayan region of India; therefore, delay in diagnosis can be prevented along with unnecessary investigations.

Abstract
BACKGROUND Among the neglected tropical diseases, leishmaniasis continues to be prevalent in many tropical and subtropical countries despite international, national, and local efforts towards its control and elimination over the last decade. This warrants a critical evaluation of such factors as under-reporting, asymptomatic infections, post kala azar dermal leishmaniasis (PKDL) cases, and drug resistance. In this review, we highlight lesser-understood atypical presentations of the disease involving atypical parasite strains against a background of classical leishmaniasis with a focus on the Indian subcontinent. METHODS AND FINDINGS A literature review based on endemic areas, the nature of disease manifestation, and underlying causative parasite was performed with data collected from WHO reports for each country. Searches on PubMed included the term ''leishmaniasis" and "leishmaniasis epidemiology" alone and in combination with each of the endemic countries, Leishmania species, cutaneous, visceral, endemic, non-endemic, typical, classical, atypical, and unusual with no date limit and published in English up to September 2017. Our findings portray a scenario with a wider distribution of the disease in new endemic foci, with new discoveries of parasite-driven atypical disease manifestations in different regions of the world. Unlike the classical picture, some Leishmania species are associated with more than one disease presentation, e.g., the L. donovani complex, generally associated with the visceral form, is now also associated with a cutaneous disease presentation, while L. tropica species complex, known to cause cutaneous disease, can cause viscerotropic disease. This phenomenon points towards the discovery of novel parasite variants as etiologic agents of atypical disease manifestations and represents an excellent opportunity to identify and study genes that control disease virulence and tropism. CONCLUSIONS The increased recognition of atypical leishmaniasis as an outcome of parasite variants has major implications for leishmaniasis control and elimination. Identifying molecular correlates of parasite isolates from distinct regions associated with different disease phenotypes is required to understand the current epidemiology of leishmaniasis in regions with atypical disease.

Abstract
A 38-year-old woman who presented with unexplained fever and pancytopenia was subjected to a bone marrow examination. Her bone marrow aspirate smear showed no obvious pathological finding except for the presence of hemophagocytosis and mild plasmacytosis. In view of hemophagocytosis, a thorough examination of the smear was conducted and revealed the presence of histoplasmosis. She was advised to undergo evaluation of her immunological status, and she tested positive for human immunodeficiency virus (HIV) infection. This case highlights that hemophagocytosis in the marrow may be an early sign of underlying disease, and that careful examination of bone marrow smears may reveal subtle infections. In addition, histoplasmosis with hemophagocytosis may be associated with pancytopenia, and hence, the HIV status of the patient should always be investigated.
