A Curious Case of Autoimmunity, Pancytopenia, and Disseminated Intravascular Coagulation.

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.

Pancytopenia Due to Folate Deficiency.

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.

Management of granulomatosis with polyangiitis complicated by intestinal perforation and pancytopenia: a case report and literature review.

Granulomatosis with polyangiitis is a systemic vasculitis. While the classic triad typically comprises otorhinolaryngologic, pulmonary, and renal manifestations, it is essential to recognize that granulomatosis with polyangiitis can affect any organ. Furthermore, reports have documented less common sites of involvement, such as the gastrointestinal tract. In this case-based review, we focus on a case of granulomatosis with polyangiitis presenting with intestinal perforation and the added challenge of concurrent pancytopenia.A 25-year-old female was diagnosed with granulomatosis with polyangiitis, with her clinical course progressing from joint pain to severe multi-organ involvement, including gastrointestinal complications. Treatment challenges emerged with the development of pancytopenia. While this may not directly result from granulomatosis with polyangiitis, it introduced an additional layer of complexity and delayed the induction of remission with immunosuppressants. Despite initial stabilization, an unexpected jejunal perforation occurred, requiring surgical intervention and subsequent postoperative care. The case underscores the complex nature of granulomatosis with polyangiitis and its potential complications. A literature search yielded discrete relevant cases in the context of our patient's intricate presentation, which has been summarized.We highlight the complexities in diagnosing and managing granulomatosis with polyangiitis-related complications, especially in uncommon presentations, and emphasize the importance of a personalized approach to patient care in these circumstances.

The impact of cytotoxic therapy on the risk of progression and death in clonal cytopenia(s) of undetermined significance.

ABSTRACT: Clonal cytopenia of undetermined significance (CCUS) is defined by a myeloid driver mutation in the context of otherwise unexplained cytopenia. CCUS has an inherent risk of progressing to myeloid neoplasm. However, it is unknown how exposure to previous cytotoxic therapy may impact the risk of progression and survival. We stratified patients with CCUS by prior exposure to DNA-damaging therapy. Of 151 patients, 46 (30%) had received cytotoxic therapy and were classified as therapy-related CCUS (t-CCUS), whereas 105 (70%) had de novo CCUS. A lower proportion of t-CCUS had hypercellular marrows (17.8% vs 44.8%, P = .002) but had higher median bone marrow blast percentages. After a median follow-up of 2.2 years, t-CCUS had significantly shorter progression-free survival (PFS, 1.8 vs 6.3 years; hazard ratio [HR], 2.1; P = .007) and median overall survival (OS; 3.6 years vs not reached; HR, 2.3; P = .007) compared with CCUS. Univariable and multivariable time-to-event analyses showed that exposure to cytotoxic therapy independently accounted for inferior PFS and OS. Despite the similarities in clinical presentation between CCUS and t-CCUS, we show that exposure to prior cytotoxic therapies was an independent risk factor for inferior outcomes. This suggests that t-CCUS represents a unique clinical entity that needs more stringent monitoring or earlier intervention strategies.

Haematological adverse effects associated with olanzapine in adolescents with anorexia nervosa: Three case reports.

OBJECTIVES: To describe haematological adverse effects in adolescents with anorexia nervosa who are taking olanzapine. METHODS: Case series report. CASE REPORT: The reported cases (two female patients and one male) were found to have blood test abnormalities after starting olanzapine and to rapidly recover their platelet and neutrophil values after the drug was discontinued. Low haemoglobin values persisted longer than observed in other series. These abnormalities became more noticeable when the dose of olanzapine was increased to 5 mg/day (initial dose 2.5 mg/day). It should be noted that two of the patients already had values indicative of mild neutropenia before they started the antipsychotic drug, and that these worsened as they continued taking the drug. In one of the patients there was only a decrease in neutrophil values, as well as mild anaemia. CONCLUSIONS: This first case series of haematological abnormalities in adolescents with anorexia nervosa who are taking olanzapine found values corresponding to pancytopenia in two of the three cases reported. It would be worthwhile to consider heightening haematological surveillance in this population when starting treatment with olanzapine and rethinking our knowledge regarding the frequency of these side effects.

[Two cases of cytopenia associated with multiple malformations]. / 血细胞减少伴多发畸形2例.

The first patient, a 10-year-old girl, presented with pancytopenia and recurrent epistaxis, along with a history of repeated upper respiratory infections, café-au-lait spots, and microcephaly. Genetic testing revealed compound heterozygous mutations in the DNA ligase IV (LIG4) gene, leading to a diagnosis of LIG4 syndrome. The second patient, a 6-year-old girl, was seen for persistent thrombocytopenia lasting over two years and was noted to have short stature, hyperpigmented skin, and hand malformations. She had a positive result from chromosome breakage test. She was diagnosed with Fanconi anemia complementation group A. Despite similar clinical presentations, the two children were diagnosed with different disorders, suggesting that children with hemocytopenia and malformations should not only be evaluated for hematological diseases but also be screened for other potential underlying conditions such as immune system disorders.

Early differential diagnosis of pancytopenia related diseases based on serum surface-enhanced Raman spectroscopy.

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.

Donor-type bone marrow aplasia following hematopoietic stem cell transplantation in a child with a novel SAMD9L variant.

Pathogenic variants in the genes SAMD9 (sterile a-motif domain containing protein - 9) and SAMD9L (SAMD9-like) cause bone marrow failure with characteristic syndromic features. We report a case of a previously healthy, 3-year-old boy with no dysmorphology, who presented with severe aplastic anemia and a novel variant in the SAMD9L gene. His father, elder brother and sister who harbored the same variant were completely healthy. In the absence of a matched unrelated donor, he underwent a stem cell transplant from his sister, a 10/10 match. Almost 2 years later he developed donor type aplasia and succumbed to an invasive fungal infection after a failed haplograft from his mother. This case highlights the pathogenicity of this previously undescribed germline variation of uncertain significance in the SAMD9L gene and the value of comprehensive genetic testing for inherited bone marrow failures even in the absence of a positive family history or characteristic congenital abnormalities.

Gaucher Disease: A First Reported Adult Case in Indonesia.

A 44-year-old female presented with a distended abdomen and fatigue. On physical examination, prominent splenomegaly was found. The laboratory investigations revealed pancytopenia and decreased albumin-globulin ratio. The abdominal ultrasonography revealed splenomegaly, cholelithiasis, and cystitis, and the bone survey showed osteopenia. Differential diagnoses included leukemia, multiple myeloma, and myelofibrosis therefore bone marrow puncture was performed. However, histopathologic examination found Gaucher-like cells in the bone marrow aspiration. The finding of CD68 positivity in Gaucher-like cells by using the immunohistochemistry staining supporting Gaucher disease. To confirm the diagnosis, an examination of glucocerebroside substrate from the patient's blood plasma was performed. Glucosylsphingosine, a deacylated form of glucosylceramide, was markedly elevated. Therefore, the diagnosis of Gaucher disease was confirmed. This is the first reported adult Gaucher case diagnosed in Indonesia.

Visceral Leishmaniasis Masquerading as Drug-Induced Pancytopenia in Lung Cancer Patients.

Maintenance chemotherapy is a standard treatment in patients with non-progressive advance staged IV non-squamous non-small cell lung cancer after induction therapy. Here, we report the case of a 53-year-old man undergoing a maintenance monotherapy with pemetrexed who presented prolonged pancytopenia despite filgrastim injections. A bone marrow aspiration revealed a macrophage activation syndrome with Leishmania amastigotes. A Polymerase Chest Reaction testing confirmed the diagnosis of visceral leishmaniasis. Treatment with liposomal amphotericin B was started. Oncologists should bear in mind that visceral leishmaniasis in endemic areas can potentially induce severe and prolonged pancytopenia in immunosuppressed patients, during chemotherapy in particular.

Pancytopenia following adjuvant therapy with interferon-gamma in a patient with disseminated nocardiosis.

A patient with disseminated nocardiosis developed pancytopenia after treatment with recombinant interferon-gamma (IFN-γ). While no previous clinical reports link pancytopenia to IFN-γ, our observations align with basic research on myelosuppressive effects of IFN-γ. Adjunctive IFN-γ may improve standard nocardiosis therapy, but vigilant monitoring of its hematologic effects is necessary.

Pancytopenia with aplastic anemia in systemic lupus erythematosus: case series and literature review.

Aplastic anemia (AA) is a rare, potentially catastrophic hematopoiesis failure manifested by pancytopenia and bone marrow aplasia. AA occurrence in Systemic Lupus Erythematosus (SLE) patients is extremely rare. The diagnosis may be delayed due to other possible pancytopenia etiologies. Confirmation of peripheral cytopenias diagnosis necessitates a bone marrow aspiration. The management of AA is challenging, and the literature reported using glucocorticoids, danazol, plasmapheresis, cyclophosphamide, intravenous immunoglobulin, and cyclosporine. We report two cases of SLE patients who presented with pancytopenia, with bone marrow biopsy confirmed AA. One case was treated with cyclophosphamide but unfortunately succumbed to Acute Respiratory Distress Syndrome (ARDS), while the other case was managed with rituximab with a good response. Interestingly, both patients were on azathioprine before the diagnosis of AA. A comprehensive search for reported cases of AA in PubMed, Scopus, and the Directory of Open Access Journals databases was performed to enhance the understanding of the diagnostic and management challenges associated with AA in SLE, facilitating ongoing exploration and research in this field. The decision to do a BM aspiration and biopsy is recommended for SLE patients with an abrupt decline in blood counts and previously stable blood counts.
