RESUMEN
HISTORY AND EXAMINATION: A 21-year-old female patient presented to us with severe low back pain for 4 months. On examination, patient was afebrile, with severe pallor, and tenderness in both sacroiliac (SI) joints. Patient was being admitted and evaluated, and during the course of evaluation, developed severe headache, which was severe in intensity and associated with nausea and projectile vomiting. Initial investigations: An X-ray of the bilateral SI joints revealed inflammation, and the antinuclear antibody (ANA) turned out to be 4+ with pancytopenia and raised lactate dehydrogenase (LDH), but the liver function tests were normal. Rest of the rheumatological profile was unremarkable. During the course of the evaluation, she developed a severe headache, which, on imaging, showed presence of cerebral edema with chronic subdural hematoma, and a concomitant coagulopathy workup revealed evidence of disseminated intravascular coagulation (DIC). DISCUSSION: Taking the whole picture into consideration, a malignant process in the body was suspected, and serum tumor markers carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and cancer antigen 125 (CA-125) were sent, all of which were raised. Validating the clinical clue was the bone marrow biopsy done for pancytopenia, which revealed malignant epithelial infiltration. A contrast-enhanced computed tomography (CECT) thorax and whole abdomen were done to find out the primary, which showed a neoplastic mass at the gastroesophageal junction along with bony metastases in the vertebrae and left adrenal. Tissue from the primary lesion was taken for histopathological examination (HPE) through upper gastrointestinal endoscopy. Although HPE revealed grade III poorly differentiated stomach adenocarcinoma, the patient had succumbed to the disease process by the time the diagnosis came to light. CONCLUSION: In short, this case perfectly illustrates how solid organ malignancies might be a mimicker of multisystem disorders, thereby delaying diagnosis and worsening the prognosis even further.

We found the article on "The Digital Technology in Clinical Medicine: From Calculators to ChatGPT" interesting.1 According to Kulkarni et al., humanity has witnesses four important social system changes, starting with the primitive huntersgatherers and progressing to horticultural, agricultural, industrial, and the current fifth, which is based on digital information technology and has altered the way we present, recognize, and utilize different factors of production. In clinical medicine, digital technology has advanced significantly since the days of computations. According to Kulkarni et al., we have to benefit from these advancements as we all improve the lives of our patients while being cautious not to overturn the doctor-patient relationship. If technology, clinical expertise, and humanistic values are properly balanced, Kulkarni et al. concluded that the future is quite glorious.1 Regulatory organizations are pushing for improvements through clinical trials as a result of recognition of the expanding influence of digital technology in healthcare delivery. The "World Health Organizations Guidelines for Digital Interventions" and the "Food and Drug Administration's Digital Health Center of Excellence" are only two of the projects that are currently being highlighted in the study as efforts to analyze and implement digital health services.

Pancytopenia is a common blood disorder defined as the decrease of red blood cells, white blood cells and platelets in the peripheral blood. Its genesis mechanism is typically complex and a variety of diseases have been found to be capable of causing pancytopenia, some of which are featured by their high mortality rates. Early judgement on the cause of pancytopenia can benefit timely and appropriate treatment to improve patient survival significantly. In this study, a serum surface-enhanced Raman spectroscopy (SERS) method was explored for the early differential diagnosis of three pancytopenia related diseases, i.e., aplastic anemia (AA), myelodysplastic syndrome (MDS) and spontaneous remission of pancytopenia (SRP), in which the patients with those pancytopenia related diseases at initial stage exhibited same pancytopenia symptom but cannot be conclusively diagnosed through conventional clinical examinations. The SERS spectral analysis results suggested that certain amino acids, protein substances and nucleic acids are expected to be potential biomarkers for their early differential diagnosis. In addition, a diagnostic model was established based on the joint use of partial least squares analysis and linear discriminant analysis (PLS-LDA), and an overall accuracy of 86.67 % was achieved to differentiate those pancytopenia related diseases, even at the time that confirmed diagnosis cannot be made by routine clinical examinations. Therefore, the proposed method has demonstrated great potential for the early differential diagnosis of pancytopenia related diseases, thus it has significant clinical importance for the timely and rational guidance on subsequent treatment to improve patient survival.

BACKGROUND: Visceral Leishmaniasis should be suspected in every patient with a history of splenomegaly, fever, and pancytopenia. It is one of the most dangerous forms of infection and prompt recognition is the key to positive outcome. CASE PRESENTATION: A 20-month-old Caucasian male patient was brought to our hospital as an outpatient with the complaint of persistent fever, which did not improve with empiric antibiotic treatment (> 96 hour after the initial dose). The antibiotic treatment had been prescribed by primary care physician at polyclinic, who also referred the patient to hematologist due to anemia, who prescribed iron supplement. Despite multiple subspecialist visits, bicytopenia was, unfortunately, left unidentified. Upon physical examination no specific signs were detected, however, spleen seemed slightly enlarged. Patient was admitted to the hospital for further work-up, management and evaluation. Abdominal ultrasound, complete blood count and c-reactive protein had been ordered. Hematologist and infectionist were involved, both advised to run serology for Epstein-Barr Virus and Visceral Leishmaniasis. The latter was positive; therefore, patient was transferred to the specialized clinic for specific management. CONCLUSION: Both in endemic and non-endemic areas the awareness about VL should be increased among the medical professionals. We also recommend that our colleagues take the same approach when dealing with bicytopenia and fever, just as with pancytopenia and fever. The medical community should make sure that none of the cases of fever and pancytopenia are overlooked, especially if we have hepatomegaly and/or splenomegaly.

OBJECTIVES: To investigate the effectiveness of donor-derived chimeric antigen receptor T (CAR-T) cells in the treatment of relapsed cases after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and whether donor-derived peripheral blood stem cells (PBSCs) have a therapeutic effect on pancytopenia after CAR-T cell therapy. METHODS: We analyzed data from five adults with B-cell acute lymphoblastic leukemia (ALL) who had relapse after allo-HSCT and received donor-derived CAR-T cell therapy and donor-derived PBSCs to promote hematopoietic recovery. RESULTS: All patients had negative minimal residual disease after CAR-T therapy, grade 1-2 cytokine release syndrome, and developed grade 4 hematologic toxicity. During the pancytopenia stage after CAR-T cell therapy, donor-derived PBSCs were transfused without graft-versus-host disease (GVHD) prophylaxis. Four patients had grade I-II acute GVHD (aGVHD). After corticosteroid treatment, aGVHD resolved and hematopoiesis was restored. Although steroids in combination with etanercept and ruxolitinib relieved symptoms in one patient with grade IV aGVHD, complete hematopoietic recovery was not achieved, and the patient died due to severe infection. CONCLUSIONS: Donor-derived CAR-T cell therapy is safe and effective in patients with relapsed/refractory ALL after allo-HSCT. Donor-derived PBSCs infusion could achieve hematopoietic recovery with controllable aGVHD in patients with persistent pancytopenia.

Toxicity associated with low doses of methotrexate (MTX) is low, but it may be fatal. Bone marrow suppression and mucositis are among the common side effects of low dose MTX toxicity. Different risk factors have been reported for toxicities associated with low doses of MTX, including accidental use of higher doses, renal dysfunction, hypoalbuminemia, and polypharmacy. In this paper, we present a female patient who had mistakenly used 7.5 mg of MTX daily instead of the same dose of MTX on Thursday and Friday. She was presented with mucositis and diarrhea to the emergency department. Moreover, we searched the databases Scopus and PubMed for available studies and case reports on toxicities associated with MTX dosing errors. The most frequently observed toxicities included gastrointestinal lesions, nausea, vomiting, skin lesions, and bone marrow suppression. Leucovorin, hydration, and urine alkalinization were among the most frequently used treatments. Finally, we summarize the data on the toxicities of low doses of MTX in different diseases.

INTRODUCTION: Gaucher's disease (GD) is a rare lysosomal storage disease. It is characterized by the deposition of glucocerebroside in cells of the macrophage-monocyte system. GD presents a broad clinical expression, including hematologic abnormalities (such as pancytopenia), massive hepatosplenomegaly, diffuse infiltrative pulmonary disease, renal involvement in the form of nephropathy and glomerulonephritis, skeletal involvement in the form of bone pain, bony infarct, osteopenia, and pathological fracture. Based on the presence or absence of neurologic involvement, it is differentiated into type 1, type 2, and type 3. Gaucher's disease type 1 is the most common form, having the nonneuropathic form and carrying autosomal recessive traits. Gaucher's disease affects all racial and ethnic groups, while type 1 GD is most prevalent among Ashkenazi Jews. CASE PRESENTATION: A 20-year-old female was admitted to the medicine department with complaints of generalized weakness and easy fatigability, menorrhagia, and a dragging sensation in the abdomen. On clinical evaluation, she had bone marrow failure syndrome features along with massive splenomegaly. Later, she was confirmed with Gaucher disease type 1 disease by clinical and investigation (low ß-glucosidase level) evaluation. CONCLUSION: This case emphasizes keeping a differential diagnosis of glycogen storage disorder while evaluating a case of unexplained pancytopenia with massive splenomegaly in adulthood for an extended period. Currently, enzyme replacement therapy and substrate reduction therapy are the mainstay therapeutic options for GD.

BACKGROUND: Vitamin B12, or cobalamin deficiency, an infrequent clinical entity in pediatric age, is found almost solely in breastfed infants whose mothers are purely vegetarian, non-supplemented or with pernicious anemia. Megaloblastic anemia in infants presents with generalized weakness or irritability. METHODS: Diagnosis is usually centered on complete blood count, vitamin dosing, and peripheral smear, which may show macrocytes, hypersegmented neutrophils, reticulocytopenia and a raised mean corpuscular volume (MCV Ë 100 fL). Pancytopenia has also been noted. RESULTS: We report an exclusive breastfed nine-month-old female child who presented with irritability, developmental delay, and difficulties in introducing new foods. Her initial blood count revealed pancytopenia. Vitamin B12 levels were found to be reduced. Maternal levels of Vitamin B12 were also found to be borderline low. The child was treated as per protocols, and improvement was evidenced with the return of hematological parameters to the regular and gradual advancement of milestones. CONCLUSIONS: We aim to underscore the importance of megaloblastic anemia as an important and rare cause of anemia in infancy.

Immune checkpoint inhibitors (ICIs) are an integral antitumor therapy for many malignancies. Most patients show very good tolerability to ICIs; however, serious immune-related adverse events (irAEs) with ICIs have been well documented and prevent some patients from continuing ICIs or even become the direct cause of patient death. Cytopenia is a rare irAE but can be life-threatening. Here, we present the case of a 66-year-old male patient with metastatic lung adenocarcinoma who received two doses of chemotherapy + PD-1 antibody tislelizumab and developed pancytopenia after each dose. Although the first episode of pancytopenia resolved with a treatment regimen of granulocyte colony-stimulating factor (G-CSF), thrombopoietin (TPO), and red blood cell and platelet transfusion, the second episode showed extreme resistance to these treatments and improved only after the administration of steroids. His second pancytopenia episode resolved after a long course of treatment with methylprednisolone, G-CSF, TPO, hetrombopag and multiple red blood cell and platelet transfusions. However, he suffered a cerebral infarction when his platelet count was in the normal range and gradually recovered 1 week later. This case highlights the importance of the early recognition and management of hematological irAEs.

BACKGROUND: Lysinuric protein intolerance is a rare inherited metabolic disease due to autosomal recessive mutations of the SLC7A7 gene. The affected patients commonly present with protein-rich food intolerance, failure to thrive, hepatosplenomegaly, muscle hypotonia and lung involvement due to impaired intestinal absorption and excessive urinary excretion of dibasic amino acids. Presentation with splenomegaly and cytopenia without other features has not been reported. Here we report a Sri Lankan girl with lysinuric protein intolerance presenting with pancytopenia and splenomegaly mimicking acute leukaemia. CASE PRESENTATION: Two years and six months old Sri Lankan girl presented with persistent pancytopenia following a viral illness. She was asymptomatic without vomiting, diarrhoea, abdominal pain or irritability. Physical examination revealed pallor and isolated firm splenomegaly of 2 cm. Growth parameters and other system examinations were normal. Full blood count revealed anaemia, leukopenia and thrombocytopenia. The blood picture showed a mixture of hypochromic microcytic and normochromic normocytic red cells with occasional pencil cells and macrocytes. Bone marrow examination was normal except for occasional megaloblasts; however, serum vitamin B12 and red blood cell folate were normal. The metabolic screen showed a high anion gap compensated metabolic acidosis, high lactate and ketosis. Genetic mutation analysis using whole exome sequencing revealed compound heterozygous variants of the SLC7A7 gene, confirming the diagnosis of lysinuric protein intolerance. CONCLUSION: We report a child with lysinuric protein intolerance presenting with pancytopenia and splenomegaly without other disease features. This case report adds to the heterogenic presentations of lysinuric protein intolerance, which is considered a multifaceted disease.

CASE PRESENTATION: A 79-year-old man was examined because of recurrent dyspnea and constitutional symptoms that included malaise, fatigue, fevers, and arthralgias over the past 7 years. He was a nonsmoker who was a retired farmer. Elevated levels of acute phase reactants and C-reactive protein and a high erythrocyte sedimentation rate were noted often in his health records. However, an extensive rheumatologic evaluation, which included serologic studies (antinuclear antibodies, cyclic citrullinated peptide antibodies, antineutrophil cytoplasmic antibodies) and temporal artery biopsy, had not shown an identifiable autoimmune disease. The patient had been treated intermittently with prednisone, with partial symptomatic improvement. Various cytopenias had been present over the preceding years; however, three bone marrow biopsy specimens showed moderately hypercellular bone marrow with no diagnostic findings.

Pancytopenia in children with celiac disease (CeD) is postulated to be due to nutritional deficiency such as vitamin B12, folate and copper or an autoimmune process resulting in aplastic anemia with hypoplastic marrow. In the present case series, we report the profile and explore the etiology of pancytopenia among children with CeD. There are only a few case reports of pancytopenia in children with CeD. We enrolled newly diagnosed cases of CeD and pancytopenia presenting in the celiac disease clinic over three years. Detailed evaluation was carried out for the cause of pancytopenia. We followed up on the cases for compliance and response to gluten-free diet at three months, six months and 12 months. Twenty patients were eligible for inclusion. They were divided into two groups: one with aplastic anemia with hypoplastic marrow labeled as Gp CeD-AA and the other with megaloblastic/nutritional anemia labeled as Gp CeD-MA. Patients in Gp CeD-MA presented with classical symptoms of CeD as recurrent diarrhea, abdomen distension, pallor and poor weight gain. They had none or just one transfusion requirement and had an early and complete recovery from pancytopenia. Patients in Gp CeD-AA presented with atypical symptoms such as epistaxis, short stature, fever, pallor and weakness. They had a multiple blood transfusion requirement and had delayed and partial recovery from pancytopenia. Pancytopenia is not a disease in itself but is the presentation of an underlying disease. It can occur due to various coexisting disorders in children with CeD, which can be as simple as nutritional deficiencies to as complex as an autoimmune process or malignancy. CeD should be included in the differential diagnosis of aplastic anemia as CeD and aplastic anemia both have a similar pathological process involving T cell destruction of tissues.

The choice to postpone treatment while awaiting genetic testing can result in significant delay in definitive therapies in patients with severe pancytopenia. Conversely, the misdiagnosis of inherited bone marrow failure (BMF) can expose patients to ineffectual and expensive therapies, toxic transplant conditioning regimens, and inappropriate use of an affected family member as a stem cell donor. To predict the likelihood of patients having acquired or inherited BMF, we developed a 2-step data-driven machine-learning model using 25 clinical and laboratory variables typically recorded at the initial clinical encounter. For model development, patients were labeled as having acquired or inherited BMF depending on their genomic data. Data sets were unbiasedly clustered, and an ensemble model was trained with cases from the largest cluster of a training cohort (n = 359) and validated with an independent cohort (n = 127). Cluster A, the largest group, was mostly immune or inherited aplastic anemia, whereas cluster B comprised underrepresented BMF phenotypes and was not included in the next step of data modeling because of a small sample size. The ensemble cluster A-specific model was accurate (89%) to predict BMF etiology, correctly predicting inherited and likely immune BMF in 79% and 92% of cases, respectively. Our model represents a practical guide for BMF diagnosis and highlights the importance of clinical and laboratory variables in the initial evaluation, particularly telomere length. Our tool can be potentially used by general hematologists and health care providers not specialized in BMF, and in under-resourced centers, to prioritize patients for genetic testing or for expeditious treatment.

Fusidic acid is an antibiotic used in the treatment of staphylococcal infections. Niraparib is an anticancer drug indicated for the treatment of advanced ovarian cancer. The interaction between these two drugs has not been studied and is not referenced in drug databases. We present the case of a patient with pancytopenia who had been treated with fusidic acid and niraparib. No other treatment was taken by this patient. According to the literature, both substances can cause haematological toxicity. It seems unlikely that this is due to niraparib alone because it had been well tolerated by the patient for over a year before the pancytopenia was diagnosed. It was also perfectly well tolerated when it was reintroduced. We cannot determine whether this pancytopenia is due to fusidic acid alone or to a drug interaction between the two treatments. We therefore recommend caution in patients treated with this combination.
