RESUMEN
Introduction: Systemic lupus erythematosus (SLE), the commonest type of lupus, is an autoimmune multisystemic disorder that can affect any organ system of the body, especially blood vessels and connective tissues, causing widespread inflammation. Pediatric onset of SLE is a rare condition with more hematological involvement. Aim: This study was undertaken to observe various hematological abnormalities and their association with various autoantibodies present in pediatric SLE in Eastern India. Methodology: It was a single-centered, cross-sectional, observational, hospital-based study conducted in the Department of Pediatric Medicine in collaboration with the Department of Rheumatology in IPGME and R and SSKM Hospital, Kolkata. The duration of the study was 1.5 years, and a total of 30 children up to 12 years of age of either gender were enrolled. Study participants were evaluated for various parameters like demographic, hematological (anemia, neutropenia, leucopenia, lymphopenia, and thrombocytopenia), biochemical (CRP, Lactate dehydrogenase (LDH), and bilirubin), autoantibodies (anti-dsDNA, anti-Ro 52, and anti-Ribonucleoprotein [RNP]), and SLE related pathologies (Cutaneous, nephritis, serositis). Results: In the present study, most of the participants had arthritis, muscle pain (86.66%), and hematological involvement (80%). Among cytopenias, anemia was the commonest. dsDNA autoantibody was positive in most of the patients (83%), and about one-third suffered from autoimmune hemolytic anemia (AIHA). No association was observed between autoantibodies and various hematological manifestations. Conclusion: It can be concluded from the present study that anemia is the most common cytopenia in pediatric SLE, but there is no association between autoantibodies and these cytopenias. However, study on larger population may give better results.
RESUMEN
Background: The aim of this study was to examine the impact of different stages of dengue infection on immune cell counts among dengue patients and to compare them with cases of non-dengue febrile illness. Methods: The recruited patients were divided into two groups: the first group served as a control (n = 55), representing non-dengue febrile illness, and the second group was identified as dengue febrile illness (n = 149), which was further divided into three groups based on infection stage. Blood samples were collected from the selected patients and subjected to blood cell component analysis. To find IgG and IgM as well as the dengue virus non-structural antigen-1 (NS1), an immunochromatographic test (ICT) kit was utilized. Additionally, a hematological analyzer was used to determine complete blood cell counts (CBC). Data was thoroughly analyzed using Graph Pad Prism 6 software. The differences in means of different groups were calculated by applying the student's t-test. Results: The findings revealed the presence of severe leucopenia and thrombocytopenia at stages 1 and 2, accompanied by lymphopenia at stage 1. Group comparisons indicated that only teenagers exhibited a significantly lower white blood cell count compared to older individuals, while no significant differences were observed in lymphocytes, platelets, and monocytes across all age groups. Comparing different age groups of normal individuals to dengue-infected patients, the results unveiled that leucopenia was most severe in adults, followed by teenagers and children, with no significant difference in the elderly. Furthermore, adults showed the greatest degree of thrombocytopenia, followed by teens and kids, with the elderly showing the greatest degree of thrombocytopenia. Adults and teens showed extreme neutrophilia, whereas young children and the elderly showed no discernible abnormalities. Elderly patients experienced a marked decrease in monocyte count, a phenomenon not observed in other age groups. Conclusion: In conclusion both, leucopenia & thrombocytopenia, are most severe in stages 1 and 2, whereas neutrophilia & lymphopenia are predominantly severe in stage 1. These results imply that the consequences associated with dengue infection are more severe in the early stages and tend to ameliorate as the patient progresses toward recovery.
RESUMEN
BACKGROUND: Thiopurine-induced leucopenia significantly hinders the wide application of thiopurines. Dose optimization guided by nudix hydrolase 15 (NUDT15) has significantly reduced the early leucopenia rate, but there are no definitive biomarkers for late risk leucopenia prediction. AIM: To determine the predictive value of early monitoring of DNA-thioguanine (DNATG) or 6-thioguanine nucleotides (6TGN) for late leucopenia under a NUDT15-guided thiopurine dosing strategy in patients with Crohn's disease (CD). METHODS: Blood samples were collected within two months after thiopurine initiation for detection of metabolite concentrations. Late leucopenia was defined as a leukocyte count < 3.5 × 109/L over two months. RESULTS: Of 148 patients studied, late leucopenia was observed in 15.6% (17/109) of NUDT15/thiopurine methyltransferase (TPMT) normal and 64.1% (25/39) of intermediate metabolizers. In patients suffering late leucopenia, early DNATG levels were significantly higher than in those who did not develop late leucopenia (P = 4.9 × 10-13). The DNATG threshold of 319.43 fmol/µg DNA could predict late leucopenia in the entire sample with an area under the curve (AUC) of 0.855 (sensitivity 83%, specificity 81%), and in NUDT15/TPMT normal metabolizers, the predictive performance of a threshold of 315.72 fmol/µg DNA was much more remarkable with an AUC of 0.902 (sensitivity 88%, specificity 85%). 6TGN had a relatively poor correlation with late leucopenia whether in the entire sample (P = 0.021) or NUDT15/TPMT normal or intermediate metabolizers (P = 0.018, P = 0.55, respectively). CONCLUSION: Proactive therapeutic drug monitoring of DNATG could be an effective strategy to prevent late leucopenia in both NUDT15/TPMT normal and intermediate metabolizers with CD, especially the former.

BACKGROUND: The dengue virus is present throughout the tropics. Thrombocytopenia is one of the severe manifestations of the dengue virus. We studied the association of thrombocytopenia with serum transaminase level, leucopenia, and nonstructural protein one antigen (Ns1Ag) level. METHODS: Data were taken retrospectively from hospital records after obtaining ethical committee approval. In the study, we included 102 patients with acute febrile illness with clinical features suggestive of dengue fever (dengue Ns1Ag positive, dengue IgM positive, or both). We excluded patients with thrombocytopenia due to other causes. Patients' demographic, clinical, and laboratory parameters were collected. We also noted episodes of bleeding or the need for a platelet transfusion. We did a statistical analysis to find out the correlation between age, sex, leucopenia, transaminitis, Ns1Ag level, and thrombocytopenia and its severity. RESULTS: Multiple regression analysis was used to find thrombocytopenia predictors among aspartate transaminase (AST), alanine transaminase (ALT), Ns1Ag level, and leucopenia. AST and ALT correlated inversely with thrombocytopenia, with p-values of 0.012 and 0.027, respectively. Ns1Ag and leucopenia were not associated with thrombocytopenia, with p-values of 0.802 and 0.532, respectively (p-values significant at 0.01<= p<=0.05). CONCLUSION: Serum AST and ALT levels correlate with thrombocytopenia in dengue fever.
RESUMEN
RESUMEN Las alteraciones en los recuentos celulares sanguíneos representan los hallazgos clínicos más notorios y recurrentes en pacientes que padecen enfermedad hepática, tanto aguda como crónica. Estos cambios constituyen un marcador importante de la disfunción hepática y, a menudo, desempeñan un papel crucial en la evaluación y manejo de estos pacientes. En conjunto con el alargamiento de las pruebas de coagulación, la trombocitopenia es la irregularidad más prevalente en estos individuos. Esta condición, así como las leucopenias, se le atribuye en gran medida al hiperesplenismo, una alteración en la que el bazo retiene y destruye las células sanguíneas, incluidas las plaquetas. Sin embargo, cuando el conteo plaquetario desciende por debajo de 10 x 103/µl, es fundamental considerar otras causas, como factores autoinmunitarios que pueden estar contribuyendo con la trombocitopenia. La anemia, definida como una disminución en el número de glóbulos rojos o en los niveles de hemoglobina, es otra característica constante que acompaña a la enfermedad hepática. Aunque en la mayoría de los casos la anemia es macrocítica, en algunas situaciones puede ser secundaria a eventos hemolíticos, como lo observado en el síndrome de Zieve. Esta diversidad en las manifestaciones de la anemia en pacientes hepáticos subraya la complejidad de las interacciones entre el hígado y los componentes sanguíneos. A pesar de los avances en la comprensión de las causas subyacentes de estas citopenias, las opciones del tratamiento siguen siendo limitadas. Generalmente, las opciones terapéuticas se enfocan en la administración de transfusiones de hemocomponentes para compensar las deficiencias en los recuentos celulares o en el uso de análogos de trombopoyetina (TPO) para estimular temporalmente la producción de las plaquetas en la medula ósea. No obstante, estos tratamientos tienden a abordar los síntomas más que las causas fundamentales de las alteraciones hematológicas en la enfermedad hepática. La persistencia y el empeoramiento de estas alteraciones pueden servir como indicadores tempranos de la progresión de la disfunción hepática. La relación intrincada entre el hígado y la homeostasis hematológica continúa siendo objeto de investigación, la compresión más profunda de estos mecanismos podría abrir potencialmente la puerta hacia enfoques terapéuticos más específicos y efectivos para abordar las citopenias en el contexto de la enfermedad hepática.
ABSTRACT Alterations in blood cell counts are the most prominent and recurrent clinical findings among patients suffering from both acute and chronic liver disease. These changes are an important marker of liver failure and often play a key role in the evaluation and management of these patients. Together with the prolongation of coagulation tests, thrombocytopenia is the most common disorder among these individuals. This condition, as well as leukopenia, is largely attributable to hypersplenism, a disorder in which the spleen retains and destroys blood cells, including platelets. However, when the platelet count drops below 10x103/µl, it is essential to consider other causes, such as autoimmune factors that may be contributing to the development of thrombocytopenia. Anemia, defined as a decrease in red blood cell count or hemoglobin levels, is another common characteristic of liver disease. Although in most cases macrocytic anemia occurs, in some situations it can be secondary to hemolytic events, as observed in Zieve's syndrome. This wide range of manifestations of anemia among liver patients highlights the complex interaction between liver and blood components. Despite advances in understanding the underlying causes of these cytopenias, treatment options remain limited. Therapeutic options generally focus on the transfusion of blood products to compensate for deficiencies in cell counts or on the use of thrombopoietin (TPO) analogues to temporarily stimulate platelet production in the bone marrow. However, these treatments tend to address the symptoms rather than the root causes of hematologic disorders in liver disease. The persistence and worsening of these disorders may serve as early indicators of the progression of liver failure. The complicated relationship between liver and hematological homeostasis remains the subject of research. A deeper understanding of these mechanisms could potentially open the door toward more targeted and effective therapeutic approaches to address cytopenias in the context of liver disease.
RESUMEN
Objective: Abnormalities in blood cells are frequently associated with thyroid hormone disorders as a result of their involvement in the proliferation and production of blood cells. This study aimed to determine the magnitude and associated factors of hematological abnormalities in patients with hypothyroidism. Methods: A cross-sectional study was conducted from January 1 to June 30, 2023, at the University of Gondar Comprehensive Specialized Hospital. The present study included a total of 300 patients with hypothyroidism prospectively using the systematic random sampling technique. The hematological parameter data were collected using data extraction sheets, whereas the associated factor data were collected using both structured questionnaires and data extraction sheets. For complete blood cell counts, 4 mL of anticoagulated venous blood was collected and analyzed. The data were entered into Epi-data version 3.1 and analyzed with Stata version 14. Both bivariate and multivariate logistic regressions were performed to identify factors associated with hematological abnormalities. A P value < 0.05 was considered to indicate statistical significance. Results: The median value of red blood cell, hemoglobin, mean cell volume, white blood cell, and platelet were 4.63 x1012/µL, 14 g/dL, 84.3fl, 5.3 x103/µL, and 228, respectively. The overall incidences of anemia, leucopoenia, and thrombocytopenia in patients with hypothyroidism were 26.3% (95% confidence interval (CI): 21-32), 15.7% (95% CI: 14.2-17.2), and 9% (95% CI: 7.5-10.5), respectively. Lymphopenia was detected in 9% (95% CI: 8.6-10.1) of the patients, and neutropenia was detected in 6% (95% CI: 4.4-7.6) of the patients. Only three factors, female sex (adjusted odds ratio (AOR) =2.1, 95% CI=1.3-3.1), alcohol consumption (AOR= 3.8, CI=1.7-8.9), and febrile illness (AOR=2.7, 95% CI=1.3-5.4), were found to be significantly associated factors for anemia. Conclusion: The present study revealed heterogeneous hematological abnormalities in patients with hypothyroidism. Thus, early diagnosis and monitoring strategies are required to minimize complications in patients.

BACKGROUND: The intravenous form of fosfomycin, a bactericide antibiotic used to treat multiresistant bacterial infections is little prescribed. The most common reported adverse effects are hypokaliemia and hypernatremia. We describe a case of agranulocytosis, a rarely described side effect that may be fatal. CASE PRESENTATION: A 45 year-old woman was admitted to the intensive care unit for post-surgical meningitis following meningioma resection. Meropenem and vancomycin were first introduced. A DRESS-syndrom with meropenem was suspected. Neutropenia was diagnosed three days after the introduction of parenteral fosfomycin and agranulocytosis four days later. Eosinophilia was also observed. A bone marrow aspiration was performed showing a disappearance of the neutrophil granulocyte line and a significant eosinophilia. Meropenem was discontinued. Fosfomycin was maintained and filgrastim was added. As filgrastim had no effect, the relationship with fosfomycin was suspected, so it was then withheld. An increase of the neutrophil count was observed. Because of the complexity of the case, the unfavorable course of the illness and the urgent need for revision surgery, a rechallenge with fosfomycin was done followed by a decrease of the neutrophil count. CONCLUSION: This is the third paper reporting agranulocytosis induced by fosfomycin, and the first detailed description of a case. Based on chronological and semiological criteria and bibliographic data, the event was qualified as probable with the Naranjo adverse drug probability scale. Literature data is scarce. The summary of product characteristics mentions that only a few cases of transient neutropenia and agranulocytosis have been reported. An analysis of the FDA Adverse Event Reporting System Database highlighted a higher than expected frequency of agranulocytosis in patients treated with fosfomycin. Parenteral fosfomycin is often used in patients receiving other medications, so that it is rarely the only suspect. In our case, the results of the bone marrow aspiration, the sudden drop of the neutrophil count with concomitant eosinophilia and the absence of improvement despite the dose decrease, point towards an immuno-allergic mechanism. However, the overlap between the suspected DRESS induced by meropenem and the agranulocytosis do not allow to conclude with certainty on the causality. Awareness should be raised about this side effect.

Tuberculosis (TB) is a significant public health problem affecting one-third of the world's population. In 2021, 1.6 million people died from TB. TB is the 13th leading cause of death and the second leading cause of infectious death after coronavirus disease 2019. Most anti-TB drugs affect hematological parameters in patients. Methods: This longitudinal prospective study was conducted from 03 January to 30 December 2019. Patients who completed a course of TB treatment were candidates for analysis. Sputum and blood samples were collected from each study participant and analyzed by the Gene X-pert machine and a HumaCount 30 hematology analyzer (Human GmbH). SPSS version 20 and R programming software version 4.2.3 were used for data analysis. Friedman's test was used to assess statistical significance. P-values ââless than 0.05 were considered statistically significant. Results: A total of 148 patients who completed the course of TB treatment correctly were a candidate for final analysis. Ninety-one (61.5%) study participants were male; the median age was 27.6±9.8 years. Moreover, most of the study participants (84.4%) had pulmonary TB. Most of the hematological parameters had changed in the phases of TB treatment. After anti-TB treatment, there is a significant difference in hematological parameters in red blood cell count, hemoglobin concentration, hematocrit percentage, platelet count, and white blood cell count. Conclusion: Anemia and leucopenia are the most significant problems after TB treatment. Regular checking of these parameters is essential for the patient.
RESUMEN
El déficit de cobre puede presentarse como una mielopatía y manifestarse como una ataxia sensorial secundaria a una desmielinización de los cordones posteriores de la médula espinal. Puede acompañarse de citopenias, principalmente anemia y leucopenia. Se presenta una serie de casos de tres pacientes con mielopatía por déficit de cobre, diagnosticados y manejados desde el año 2020 al 2022 en un hospital universitario de alta complejidad en Colombia. Dos de los casos eran mujeres. El rango de edad fue entre 57 y 68 años. En los tres casos, los niveles séricos de cobre estaban disminuidos y en dos de ellos, se descartaron diferentes causas de mielopatía que afectan los cordones posteriores de la médula espinal como el déficit de vitamina B12, vitamina E y ácido fólico, tabes dorsal, mielopatía por virus de la inmunodeficiencia humana, esclerosis múltiple e infección por el virus linfotrópico humano de tipo I y II, entre otras. Sin embargo, un paciente tenía deficiencia de vitamina B12 asociada con de cobre en el momento del diagnóstico de la mielopatía. En los tres casos hubo ataxia sensitiva y en dos, la paraparesia fue el déficit motor inicial. Se deben incluir siempre la determinación de los niveles de cobre dentro del abordaje diagnóstico de todo paciente con enfermedad gastrointestinal crónica, con diarrea crónica, síndrome de mala absorción o reducción significativa de la ingestión en la dieta, y que desarrolle síntomas neurológicos sugestivos de compromiso de los cordones, ya que se ha reportado que el retraso en el diagnóstico de las mielopatías se asocia con pobres desenlaces neurológicos.
Copper deficiency can present as myelopathy by the manifestation of sensory ataxia, secondary to demyelination of the posterior cords of the spinal cord, accompanied by cytopenia, mainly anemia, and leukopenia. Case series study of three patients with myelopathy due to copper deficiency, diagnosed and managed from 2020 to 2022 in a highly complex university hospital in Colombia. Regarding gender, two cases were female patients. The age range was between 57 and 68 years. In all three cases serum copper levels were decreased, and in two of these, different causes of myelopathy affecting the posterior cords of the spinal cord were ruled out, such as vitamin B12, vitamin E and folic acid deficiency, tabes dorsalis, myelopathy due to human immunodeficiency virus, multiple sclerosis and infection by the human lymphotropic virus type I and II, among others. However, at the moment of the myelopathy diagnosis, one patient had vitamin B12 deficiency associated with copper insufficiency. All three cases presented sensory ataxia, and in two, paraparesis was the initial motor deficit. The diagnostic approach must include copper levels assessment in every case of patients with chronic gastrointestinal pathology, chronic diarrhea, malabsorption syndrome, or significant reduction in dietary intake; and the development of neurological symptoms that may suggest cord involvement. It has been reported that a delay in diagnosis can lead to poor neurological outcomes.

Protein-losing enteropathy (PLE) is one of the rare gastrointestinal manifestations of systemic lupus erythematosus (SLE), which can manifest several years before the diagnosis of SLE. PLE should be suspected in patients with hypoalbuminemia in the absence of urinary protein loss and normal liver functions without any other manifestations of malnutrition. Due to the non-specificity of the imaging and histological findings, it is difficult to diagnose PLE in resource-limited settings. Thus, it is underdiagnosed. We report the case of a 38-year-old Sri Lankan (South Asian) female who is a diagnosed patient with hypothyroidism and has presented with worsening generalized body swelling and ascites for two months. She had hypoalbuminemia without proteinuria. Thus, the clinical diagnosis of PLE was suspected. The diagnosis of SLE was suspected because of significant alopecia, high titer (1:1000) antinuclear antibody (ANA) positivity, and hypocomplementemia. Though confirmatory tests such as Tc-99 albumin scintigraphy and stool alpha-1 anti-trypsin were not available in our resource-limited setting, the diagnosis of the SLE-associated protein-losing enteropathy was made as the patient fulfilled the European Alliance of Associations for Rheumatology (EULAR) criteria for SLE and also by excluding all the other possible causes of PLE.
RESUMEN
Paclitaxel frequently induces peripheral neuropathy and myelosuppression during cancer treatment. According to the National Health Insurance Research Database of Taiwan, traditional Chinese medicine doctors widely use Xiang Sha Liu Jun Zi Tang (XSLJZT) to treat breast cancer patients who have received paclitaxel. We explored the combined therapeutic effects of XSLZJT with paclitaxel. XSLJZT did not exhibit significant cytotoxic effects on P388-D1 cells; however, the combination of XSLJZT (100 and 500 mg/kg) with paclitaxel prolonged the survival rate in P388-D1 tumor-bearing mice compared to paclitaxel-only. In addition, XSLJZT was found to enhance white blood cells (WBC) counts and promote leukocyte rebound in paclitaxel-induced leukopenia in mice. XSLJZT also reduced paclitaxel-induced mechanical pain and inhibited c-Fos protein expression in the L4-6 spinal cords of Wistar rats. Moreover, paclitaxel-induced shortening of the nerve fibers of dorsal root ganglion cells was ameliorated by pre-treatment with XSLJZT. Therefore, we suggest that XSLJZT could be used as an adjunct for cancer patients, as the formula could decrease paclitaxel-induced neuropathy and myelosuppression.
RESUMEN
Leucocyte subpopulations in both lymphoid and myeloid lineages have a significant impact on antitumor immune response. While radiation-induced lymphopenia is being studied extensively, radiation effects on lymphoid and myeloid subtypes have been relatively less addressed. Interactions between leucocyte subpopulations, their specific radiation sensitivity and the specific kinetics of each subpopulation can be modeled based on both experimental data and knowledge of physiological leucocyte depletion, production, proliferation, maturation and homeostasis. Modeling approaches of the leucocyte kinetics that may be used to unravel mechanisms underlying radiation induced-leucopenia and prediction of changes in cell counts and compositions after irradiation are presented in this review. The approaches described open up new possibilities for determining the influence of irradiation parameters both on a single-time point of acute effects and the subsequent recovery of leukocyte subpopulations. Utilization of these approaches to model kinetic data in post-radiotherapy states may be a useful tool for further development of new treatment strategies or for the combination of radiotherapy and immunotherapy.

RESUMEN
Resumen ANTECEDENTES: Las repercusiones del embarazo en el síndrome de plaquetas grises no están definidas, la bibliografía reporta pocos casos; por tanto, los desenlaces no son muy conocidos. OBJETIVO: Describir el caso de una paciente con síndrome de plaquetas grises y embarazo para proponer pautas de atención y recomendaciones para el seguimiento antenatal, peri y posparto en este grupo de pacientes. Además, revisar la bibliografía más reciente. CASO CLÍNICO: Paciente primigesta de 29 años, con diagnóstico de trombocitopenia a partir de los 6 años. Durante el embarazo se consideró de origen genético por lo que se solicitó el exoma clínico que reportó una variante en el gen NBEAL2 c 7244G>T p G1y2415Val homocigoto, con diagnóstico de síndrome de plaquetas grises. Permaneció en seguimiento en los servicios de Hematología y Obstetricia, sin complicaciones mayores; cerca del parto requirió transfusión de plaquetas. A las 39 semanas de embarazo ingresó para atención del parto, se dio prueba de trabajo de parto; sin embargo, por indicación obstétrica (detención de la dilatación) se decidió la finalización mediante cesárea. METODOLOGÍA: Se revisaron las bases de datos de PubMed, LILACS, Medline, Clinical trials de los últimos 20 años. Los MeSH de búsqueda fueron "grey platelet" "syndrome" "pregnancy". Se encontraron 11 artículos de los que se descartaron 2 por estar fuera del rango de tiempo, un artículo duplicado y otros excluían embarazadas. En total se revisaron 9 artículos. CONCLUSIÓN: Este caso muestra que las mujeres con síndrome de plaquetas grises, si son debidamente acompañadas por un equipo interdisciplinario con experiencia pueden tener un embarazo y parto seguros.
Abstract BACKGROUND: The repercussions of pregnancy in grey platelet syndrome are undefined, with few cases reported in the literature; therefore, outcomes are not well known. OBJECTIVE: To describe the case of a patient with grey platelet syndrome and pregnancy in order to propose care guidelines and recommendations for antenatal, peri- and postpartum follow-up in this group of patients. In addition, to review the most recent literature. CLINICAL CASE: A 29-year-old primigravida patient diagnosed with thrombocytopenia since the age of 6. During pregnancy it was considered to be of genetic origin, so the clinical exome was requested, which reported a variant in the NBEAL2 c 7244G>T p G1y2415Val homozygous gene, with a diagnosis of grey platelet syndrome. She remained under follow-up in the haematology and obstetrics departments, without major complications; close to delivery she required platelet transfusion. At 39 weeks of pregnancy, she was admitted for delivery care, proof of labour was given; however, due to obstetric indications (arrest of dilatation) it was decided to terminate the pregnancy by caesarean section. METHODOLOGY: The databases of PubMed, LILACS, Medline, Clinical trials of the last 20 years were reviewed. The MeSH search terms were "grey platelet" "syndrome" "pregnancy". Eleven articles were found of which two were discarded for being out of time range, one article duplicated and others excluded pregnant women. In total 9 articles were reviewed. CONCLUSION: This case shows that women with grey platelet syndrome, if properly supported by an experienced interdisciplinary team, can have a safe pregnancy and delivery.
RESUMEN
The blood cell count is often examined in routine clinical praxis. Physiologic leucocyte count is in range 4-10 × 109 in liter of blood. Abnormal values of leukocytes and subtypes of leukocytes in differential count are often present. Changes in leukocytes counts are caused by variety of benignant or malignant conditions. It is important in clinical praxis to interpret changes in blood cell count correctly and choose adequate approach in investigation process. In general, leukocytosis and leukocytopenia may present in primary hematologic disorder or secondary/reactive states, caused by reaction of hematopoiesis to underlying condition. This article review common causes of leukocytosis or leucopenia and give basic advice how to investigate patients with changes in leukocytes count.

Data is presented as mean±SD and frequency and percentages for numerical and categorical variables respectively using tables and figures. Results: In this study the mean age of patients was 34.36 ± 6.41 years with male to female ratio 2.52: 1. Frequency of anemia was 82.6% (n=413), leukocytosis was 46.2% (n=231) and leucopenia in 102 patients (20.4%). Thrombocytosis was detected in 131(26.2%) patients. Raised ESR was observed in 495(99%) of the patients. No association of age and gender was observed with hematological manifestations. However, thrombocytosis was significantly more common in male patients (p-value = 0. 008). Conclusion: Hematological parameters like high Erythrocyte Sedimentation Rate (ESR) and anemia were commonly detected in newly diagnosed patients with pulmonary tuberculosis. Thrombocytosis was seen more commonly in male patients of pulmonary tuberculosis.
RESUMEN
Background: Dengue fever is a mosquito borne disease commonly manifest leucopoenia and thrombocytopenia. Dengue fever and its complications like bleeding manifestation can be life threatening. This study was conducted to study the effect of doxycycline and doxycycline with carica papaya on thrombocytopenia and leucopoenia in acute dengue fever patients. Methods: This case control study was conducted amongst the patients suffering from dengue fever with thrombocytopenia. Cases were dengue patients with thrombocytopenia and leucopenia both. Controls were dengue patients with thrombocytopenia with normal leukocyte count. An effect of doxycycline and doxycycline with carica papaya was observed on platelet and leukocyte counts at baseline and first, second, fourth, and seventh day in cases and comparison was done. Results: The maximum improvement in mean platelet count and leukocyte count was observed in doxycycline with carica papaya group followed by doxycycline alone group followed by controls (conservative treatment) in decreasing order on day 4th and 7th day of admission. Reduced hospital stay was also in the same order. Conclusion: The study results indicate that doxycycline and carica papaya are useful modality to improve leucopenia and thrombocytopenia in dengue patients and to minimize hospital stay.
RESUMEN
Tuberculosis (TB) infection of the genitourinary tract (GU TB) is rare in renal transplant recipients, with only a few published case series. GU TB is difficult to diagnose with or without immunosuppression but must always be suspected in any patient with unexplained sterile pyuria. As GU TB is associated with graft rejection, prompt diagnosis and treatment are vital. Treatment is challenging, as rifampicin, the most effective drug used to treat tuberculosis, is a significant inducer of cytochrome P-450 3A metabolism, with the potential to cause significant reductions in the serum levels of calcineurin inhibitors. For this reason, rifabutin, a weaker cytochrome P-450 3A inducer, with similar efficacy against TB, is sometimes used as an alternative to rifampicin in transplant recipients. We present a renal transplant patient diagnosed with GU TB, treated with a regime containing rifabutin, who subsequently developed profound hyponatremia and leucopenia. Serum and urine biochemistry was consistent with a diagnosis of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Both SIADH and leucopenia resolved with rifabutin cessation. This is the first report of biochemically proven, idiosyncratic SIADH and leucopenia associated with the use of rifabutin in the treatment of GU TB in a renal transplant recipient.
RESUMEN
Introducción: la asociación de leucopenia, linfopenia y neutropenia con la presencia de autoanticuerpos, manifestaciones clínicas e infecciones en pacientes con lupus eritematoso sistémico (LES) no está bien establecida. Los objetivos de este estudio fueron analizar los cambios en los recuentos de leucocitos y linfocitos en pacientes con LES y su asociación con manifestaciones clínicas, autoanticuerpos y riesgo de infecciones. Materiales y métodos: se recolectaron retrospectivamente los valores de leucocitos, linfocitos y neutrófilos. Se agruparon a los pacientes en cinco categorías: recuento de glóbulos blancos normales, leucopenia (persistente o intermitente) y linfopenia (persistente o intermitente). Se registraron las manifestaciones clínicas, los autoanticuerpos acumulados, el daño, la mortalidad, las infecciones y los tratamientos inmunosupresores recibidos de cada paciente. Resultados: se incluyeron 89 pacientes. La linfopenia (89%) fue la anormalidad más frecuente. La leucopenia intermitente y la persistente se detectaron en el 44% y en el 11% de los pacientes, respectivamente. La linfopenia intermitente y la persistente se hallaron en el 44% y en el 45% de los casos. En el análisis univariado, la presencia de rash discoide se asoció a leucopenia (20,4 vs. 5,1; p=0,059) y el tratamiento con mofetil micofenolato a un recuento normal de leucocitos (p=0,046). El compromiso neurológico se asoció a recuento normal de linfocitos (22,2% vs. 0% y 7,5%; p=0,027); los pacientes con anti-RNP (anti ribonucleoproteína nuclear) presentaron más frecuentemente linfopenia persistente (47% vs. 15,4% y 20%; p=0,007). Ninguno de los grupos se asoció a una mayor prevalencia de infecciones. En el análisis multivariado, el mofetil micofenolato se asoció negativamente a leucopenia (OR 0.33 IC 95% 0,1-0,9; p=0,042) y el compromiso neurológico se asoció negativamente a linfopenia (OR 0.08; p=0,022). Conclusiones: en el análisis univariado, el rash discoide se asoció a leucopenia y el anti-RNP a linfopenia. Al ajustar por otras variables significativas, el tratamiento con mofetil micofenolato se asoció a un recuento normal de leucocitos, mientras que las manifestaciones neurológicas se relacionaron a linfocitos normales. No se demostró asociación de las infecciones con ninguno de los grupos.
Introduction: leukopenia, lymphopenia and neutropenia association to clinical manifestations and infections in systemic lupus erythematosus (SLE) is not well defined. The objectives were to analize leucocytes and lymphocytes variations in SLE patients and their association to clinical manifestations, autoantibodies and infections risk. Materials and methods: total white blood cell (WBC) count, lymphocyte, and neutrophils counts were collected retrospectively. Data were grouped into normal WBC cell count, persistent or intermittent leucopenia and lymphopenia. Disease manifestations, accumulated autoantibodies, damage, mortality, infections and immunosuppressants ever received were registered. Results: study sample included 89 patients. Lymphopenia (89%) was the most common abnormality. Intermittent and persistent leukopenia were detected in 44% and 11% cases. Intermittent and persistent lymphopenia were found in 44% and 45% cases. In univariate analysis, discoid rash was associated to leukopenia (20.4 vs 5.1 p=0.059) and mycophenolate treatment to normal leukocyte count (p=0.046). Patients with neurological disorder tended to have normal lymphocyte counts rather than intermittent or persistent lymphopenia (22.2% vs 0% and 7.5% p=0.027); patients with anti-RNP tended to belong to the persistent lymphopenia group (47% vs 15.4% and 20% p=0.007). Infections were not associated to any of the categories. In multivariate analysis mycophenolate was negatively associated to leukopenia (OR 0.33 95% CI 0.1-0.9 p=0.042) while neurological disorder was negatively associated to lymphopenia (OR 0.08 p=0.022). Conclusions: in univariate analysis, discoid rash was associated to leukopenia and anti-RNP to lymphopenia. When adjusted to other significant variables, mycophenolate was related to normal leukocyte while neurological manifestations were to normal lymphocyte counts. Infections were not associated to any of the categories.
