BACKGROUND: Lymphocyte expansion and true lymphocytosis are commonly observed in the everyday clinical practice. The meaning of such phenomenon is often poorly understood so that discrimination between benign and malignant lymphocytosis remains difficult to establish. This is mainly true when lymphocytosis rises in patients affected by immune-mediated chronic inflammatory diseases under immunosuppressive treatment, conditions potentially associated with lymphomagenesis. In this brief report the development of mild T CD4(pos) lymphocytosis in a group of patients with chronic arthritis under anti-TNF-α treatment is described...

REVIEW
Consolato Sergi, Fan Shen, Gerd Bouma
The upper digestive tract is routinely scoped for several causes of malabsorption, and the number of duodenal biopsy specimens has increased notably in the last 10 years. Gluten-sensitive enteropathy (GSE) is an autoimmune disease, which shows an increasing prevalence worldwide and requires a joint clinico-pathological approach. The classical histopathology of GSE with partial or total villous blunting is well recognized, but the classification of GSE is not straightforward. Moreover, several mimickers of GSE with intraepithelial lymphocytosis have been identified in the last 20 years, with drug interactions and medical comorbidities adding to the conundrum...

BACKGROUND: Trisomy 12 chronic lymphocytic leukemia (CLL) is phenotypically different from the rest of CLL cytogenetic subgroups. However, it is unknown whether this is also the case for trisomy 12 CLL-phenotype monoclonal B-cell lymphocytosis (MBL). METHODS: We analyzed the expression of several markers in a series of 89 cytogenetically characterized MBL (including 17 trisomy 12 cases). Additionally, we compared the expression of these markers between trisomy 12 MBL, trisomy 12 CLL and a series of cases with trisomy 12 but fulfilling only 3 of the 5 Moreau CLL diagnostic criteria...

We report the case of a 54-year-old woman with multiple presentations to the emergency department with severe headache, transient variable neurological deficits and normal investigations aside from CSF lymphocytosis. This represents a rare but under-diagnosed condition, transient headache and neurological deficits with cerebrospinal fluid lymphocytosis (HaNDL) syndrome. HaNDL is an important differential diagnosis for headache. We summarise the current knowledge about its clinical course, diagnosis and typical investigation findings...

Giardiasis is the most common intestinal parasitic infection in the United States. The organism elicits no, or minimal, inflammatory changes in duodenal biopsy samples, so it can be easily overlooked. We performed this study to determine whether Giardia could be isolated from the formalin fixative of biopsy samples, and to evaluate the value of fluid analysis in the assessment for potential infection. We prospectively evaluated duodenal biopsy samples from 92 patients with a clinical suspicion of giardiasis or symptoms compatible with that diagnosis (ie, diarrhea, bloating, or abdominal pain) Biopsy samples were routinely processed and stained with hematoxylin and eosin...

The usefulness of the complete blood count (CBC) during the first week of life in infants with Down syndrome (DS) has been recognized; however, studies are limited and have evaluated only some of the parameters of the CBC. Here, we report a prospective study of 135 infants with cytogenetically confirmed DS and a reference group of 226 infants without birth defects all born during the period 2009-2015 at the Dr. Juan I. Menchaca Civil Hospital of Guadalajara (Guadalajara, Mexico). The goal was to evaluate hematological findings in the CBC during the first 7 days of life, interpreted according to gestational and postnatal age...

One of the hallmarks of Celiac disease (CD) is intraepithelial lymphocytosis in the small intestine. Until now, investigations to characterize the T cell subpopulations within the epithelial layer have not discriminated between the heterodimeric co-receptor molecule, CD8αβ, and the possibly immunoregulatory CD8αα homodimer molecule. Besides TCRαβ+ CD4+ cells, no other phenotypes have been shown to be gluten-reactive. Using flow cytometry on lymphocytes from duodenal biopsies, we determined that the number of B cells (CD3- CD19+) and the number of CD3+ CD4- CD8- double-negative (DN) T cells were elevated 6-7 fold in children with CD...

The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HANDL) is rare; it comprises migrainous headaches (generally in headache-naïve people), fluctuating neurological symptoms and cerebrospinal fluid (CSF) lymphocytosis. The syndrome generally runs a benign, self-limiting course over weeks. A small proportion of patients develop intracranial hypertension as a consequence of the illness. Recurrence of headaches or development of visual symptoms following apparent recovery from HANDL should prompt urgent re-evaluation for elevated intracranial pressure...

INTRODUCTION: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare but life-threatening reaction to drugs such as carbamazepine and allopurinol. The condition is characterized by skin rashes, fever, hematological disturbances, lymphadenopathy, and organ failure, most probably hepatic dysfunction. To date, only a few cases of valproate-induced DRESS syndrome have been reported. CASE PRESENTATION: We report on the case of a 60-year-old man who had been treated with valproic acid some time before being referred to Kowsar Hospital, Semnan, Iran in December 2015...

Limited information is available regarding the incidence and features of lymphocyte expansions after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Large granular lymphocytes (LGL) expansions have been reported after bone marrow or peripheral blood, but not after unrelated cord blood (UCB) allo-HSCT, associated with indolent clinical courses and favorable outcomes. Here, we considered 85 recipients of UCB allo-HSCT to more broadly define the impact of lymphocytosis, not limited to LGL. Sustained lymphocytosis was observed in 21 (25%) patients at a median onset of 12...

BACKGROUND: Two old drugs are the only choice against Trypanosoma cruzi and little is known about their secondary effects in the acute stage of oral-transmitted Chagas disease (ChD). METHODS: A cross-sectional analytical surveillance study was conducted in a sizable cohort of patients seen during the largest acute foodborne ChD microepidemic registered so far. Individuals were treated with benznidazole (BNZ) or nifurtimox (NFX). "Common Terminology Criteria for Adverse Events" was assessed to categorize side effects according to severity...

We report the case of a 49-year-old man who experienced dry cough and itching eruption for 2 months. The patient had Gottoron's sign, mechanic's hand, and high levels of serum Krebs von den Lungen-6 and surfactant protein D, but was negative for anti-aminoacyl transfer RNA synthetase antibodies. High-resolution chest computed tomography revealed subpleural band-like or patchy consolidation with predominance in the bilateral lower lobe. Bronchoalveolar lavage fluid showed increased total cell counts with lymphocytosis...

AIMS: Epstein-Barr virus-positive (EBV(+) ) intestinal T/NK-cell lymphoma (ITNKL) is an uncommon tumour with an extremely aggressive clinical behavior. However, the clinicopathological characteristics of this tumour, including T-cell receptor (TCR) phenotype and the patient's background, remain unknown. The aim of this study was to elucidate the detailed clinicopathological profile of EBV(+) ITNKL. METHODS AND RESULTS: We enrolled 12 patients with EBV(+) ITNKL without nasal involvement in the study...

Large granular lymphocyte (LGL) leukemia has been recognized by the WHO classifications among mature T cell and NK cell neoplasms. There are 3 categories: chronic T cell leukemia and NK cell lymphocytosis which are similarly indolent diseases characterized by cytopenias and autoimmune conditions as opposed to aggressive NK cell LGL leukemia. Clonal LGL expansion arise from chronic antigenic stimulation which promotes dysregulation of apoptosis, mainly due to constitutive activation of survival pathways including Jak/Stat, MapK, Pi3k-Akt, RasRaf-1, MEK1/ERK, sphingolipid, and NFκB...

The syndrome of transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis (HaNDL), is a rare, benign, self-limiting syndrome that is not well known. Cerebrospinal fluid examination (CSF) on clinical suspicion has diagnostic value for this syndrome, which has a rich neurological symptomatology that can mimic many diseases causing mortality and morbidity. Although the ethiopathogenesis of this syndrome is not fully known, autoimmunity is thought to be in the foreground. Described in this article is a HaNDL case that on first clinic presentation appeared to be a transient ischemic attack (TIA) with temporary but recurring neurological findings and normal CSF pressure accompanied by papilledema...

Ibrutinib (Imbruvica(®)) is an oral irreversible inhibitor of Bruton's tyrosine kinase, a B-cell receptor (BCR) signalling kinase expressed by various haematopoietic cells, B-cell lymphomas and leukaemias. The drug is indicated for the treatment of certain haematological malignancies, including chronic lymphocytic leukaemia (CLL)/small lymphocytic lymphoma (SLL), which are the focus of this review. In phase III CLL/SLL trials, ibrutinib monotherapy was more effective than chlorambucil in the first-line treatment of elderly patients (RESONATE-2) and more effective than ofatumumab in previously-treated adults (RESONATE)...

The magnitude of lymphocytosis following exercise is directly related to exercise intensity. Infection with cytomegalovirus (CMV) also augments lymphocytosis after exercise. It is not known if the enhanced T-cell response to exercise due to CMV depends on exercise intensity. Furthermore, exercise-induced changes in T-cell expression of type I and type II cytokines are thought to be intensity dependent, but direct comparisons are lacking. The aim of this experiment was to determine if CMV affects the exercise-induced redistribution of T-cell subsets at varying intensities, and determine the effect of exercise intensity on CD8(+) T-cell cytokine expression...

BACKGROUND: Measles caused by a paramyxovirus, characterized by fever, malaise, cough, coryza conjunctivitis, a maculopapular rash is known to result in pneumonia, encephalitis and death. Fatal cases of measles in Sri Lanka are rare after implementation of the National Immunization Programme in 1984. Thereafter 0.1% case fatality rate was observed during October 1999-June 2000 which is a very low figure compared to other regional countries. Immunization guidelines were further revised in 2001, 2011 and in 2012 when additional immunization was recommended to age group 4-21 years; who are likely to have inadequate immunization, in order to achieve elimination of Measles by 2020...
