Despite endometriosis being a relatively common chronic gynecological condition in women of childbearing age, small bowel endometriosis is rare. Presentations can vary from completely asymptomatic to reported symptoms of abdominal pain, bloating, and diarrhea. The following two cases depict very atypical manifestations of ileal endometriosis that presented as obscure intermittent gastrointestinal bleeding and bowel obstruction requiring surgical intervention. The first case describes a previously healthy 40-year-old woman with severe symptomatic iron deficiency anemia and intermittent melena. A small bowel enteroscopy diagnosed multiple ulcerated strictures in the distal small bowel as the likely culprit. Despite nonsteroidal anti-inflammatory drug-induced enteropathy being initially considered as the likely etiology, histopathological examination of the resected distal ileal segment revealed evidence of endometriosis. The second case describes a 66-year-old with a presumptive diagnosis of Crohn's disease who reported a 10-year history of intermittent perimenstrual abdominal pain, diarrhea, and nausea with vomiting. Following two subsequent episodes of acute bowel obstruction and surgical resection of the patient's stricturing terminal ileal disease, histopathological examination demonstrated active chronic inflammation with endometriosis. Small bowel endometriosis should be considered as an unusual differential diagnosis in women who may present with obscure gastrointestinal bleeding from the small bowel or recurrent bowel obstruction.

Introduction: Anemia is a highly prevalent disorder. Preoperative anemia is associated with higher mortality, more complications, longer hospital stays, and higher healthcare costs. Red blood cell transfusion (RBC) does not improve these outcomes. The World Health Organization recommends implementing Patient Blood Management (PBM) programmes, as they can improve these clinical outcomes, reduce unnecessary RBC transfusions, and save costs. Despite compelling evidence, the implementation of these measures has yet to be effectively achieved. The objective of this study is to conduct a situational analysis to raise awareness about this issue and encourage the implementation of these measures. Methodology: An observational, longitudinal, retrospective cohort study was conducted at a single center. All patients undergoing elective surgery from 01/01/2022 to 01/04/2022 at the Hospital de Clínicas were included. Exclusion criteria: absence of a complete blood count in the three months prior to surgery and refusal to participate in the study. Results: A total of 329 surgeries were analyzed. 52 out of 100 procedures were performed on patients with anemia. A statistically significant association was found between preoperative anemia and receiving RBC transfusion during hospitalization. OR 11.746 (4.518 - 30.540). Anemia and RBC transfusions significantly prolonged hospital stay. Length of hospitalization based on patient condition: No anemia: 10.1 ± 1.1 days, with anemia: 27.2 ± 2.3 days. Value of p < 0.001. Non-transfused: 14.5 ± 1.3 days, transfused: 41.8 ± 4.4 days. Value of p < 0.001. Only 49 (28.6%) of the 171 patients with anemia had iron metabolism assessed before surgery. Among the 140 patients with Hb < 12 g/dL undergoing surgeries with non-insignificant bleeding, only 4 received specific treatment to optimize Hb. A total of 185 units of red blood cells (RBC) were administered during hospitalization. 49 to unstable patients (intraoperative or acute hemorrhage) and 136 to stable patients. From the analysis of the latter group, 42.5% of the patients received 3 or more RBC units. The average pre-transfusion hemoglobin was 7.0 ± 0.1. A statistically significant association was found between receiving RBC units and dying during hospitalization. OR 17.182 (3.360 - 87.872). Conclusiones: A situational analysis was conducted, revealing a high prevalence of preoperative anemia, scarce study and treatment of anemia before surgeries, and an excessive amount of blood transfusions received by some patients. This work establishes the need to implement Patient Blood Management programs to reduce the prevalence of preoperative anemia and improve our transfusion practices. It also sets a comparative framework to evaluate the progress of these measures and indicates possible indicators to assess the benefits of their implementation.
Introdução : A anemia é um distúrbio altamente prevalente. A anemia pré-operatória está associada a maior mortalidade, mais complicações, tempo prolongado de internação e maiores custos de saúde. A transfusão de glóbulos vermelhos (TGV) não melhora esses resultados. A Organização Mundial da Saúde recomenda a implementação de medidas de Gerenciamento de Sangue do Paciente (GSP), pois permitem melhorar esses resultados clínicos, reduzir TGV desnecessárias e economizar custos. Apesar da evidência contundente, a implementação dessas medidas ainda está aquém de ser efetivada. O objetivo deste trabalho é realizar uma análise da situação para conscientizar sobre o problema e incentivar a implementação dessas medidas. Metodologia: Foi realizado um estudo observacional, longitudinal, retrospectivo de coorte histórica, unicêntrico. Foram incluídos todos os pacientes submetidos a cirurgias de coordenação de 01/01/2022 a 01/04/2022 no Hospital de Clínicas. Critérios de exclusão: ausência de hemograma nos três meses anteriores à cirurgia e recusa em participar do estudo. Resultados: Foram analisadas um total de 329 cirurgias. 52 a cada 100 procedimentos foram realizados em pacientes com anemia. Foi encontrada uma associação estatisticamente significativa entre a anemia pré-operatória e a recepção de TGR durante a internação. OR 11,746 (4,518 - 30,540). A anemia e as TGR prolongaram significativamente a internação hospitalar. Dias de internação em função da condição do paciente: Sem anemia: 10,1 ± 1,1 dias, com anemia: 27,2 ± 2,3 dias. Valor p < 0,001. Não transfundidos: 14,5 ± 1,3 dias, transfundidos: 41,8 ± 4,4 dias. Valor p < 0,001. Apenas 49 (28,6%) dos 171 pacientes com anemia tinham metabolismo do ferro antes da cirurgia. Dos 140 pacientes com Hb < 12 mg/dL submetidos a cirurgias com sangramento não insignificante, 4 receberam tratamento específico para otimizar a Hb. Foram administradas um total de 185 unidades de glóbulos vermelhos (UGV) durante a internação. 49 em pacientes instáveis (intraoperatório ou hemorragia aguda) e 136 em pacientes estáveis. Da análise desses últimos, 42,5% dos pacientes receberam 3 ou mais UGV. A hemoglobina pré-transfusional média foi de 7,0 ± 0,1. Foi encontrada uma associação estatisticamente significativa entre receber UGV e falecer durante a internação. OR 17,182 (3,360 - 87,872). Conclusões: Foi realizado uma análise da situação na qual foi observada uma elevada prevalência de anemia pré-operatória, um estudo e tratamento escasso da anemia antes das cirurgias e uma quantidade excessiva de UGV recebidas por alguns pacientes. Este trabalho estabelece a necessidade de implementar programas de Gerenciamento de Sangue do Paciente para reduzir a prevalência de anemia pré-operatória e melhorar nossas práticas transfusionais. Além disso, estabelece um quadro comparativo para avaliar o progresso dessas medidas e aponta possíveis indicadores para avaliar os benefícios de sua implementação.

Introduction: Fanconi anemia (FA) is a genomic instability disorder associated with congenital abnormalities, including short stature and the presence of central nervous system anomalies, especially in the hypothalamic-pituitary area. Thus, differences in pituitary size could associate with the short stature observed in these patients. Our aim was to evaluate whether central nervous system abnormalities and pituitary gland volume correlate with height and hormone deficiencies in these patients. Methods: In this cross-sectional exploratory study 21 patients diagnosed with FA between 2017 and 2022 in a Spanish Reference Center were investigated. Magnetic resonance imaging (MRI) was performed and pituitary volume calculated and corelated with height and other endocrine parameters. Results: The percentage of abnormalities in our series was 81%, with a small pituitary (pituitary volume less than 1 SD) being the most frequent, followed by Chiari malformation type 1. The median value of pituitary volume was -1.03 SD (IQR: -1.56, -0.36). Short stature was found in 66.7% [CI95% 43-85.4]. Total volume (mm3) increases significantly with age and in pubertal stages. There were no differences between volume SD and pubertal stage, or the presence of endocrine deficiencies. No correlations were found between pituitary volume and the presence of short stature. The intraclass correlation index (ICC) average for volume was 0.85 [CI95% 0.61-0.94] indicating a good-to-excellent correlation of measurements. Discussion: Central nervous system anomalies are part of the FA phenotype, the most frequent after pituitary hypoplasia being posterior fossa abnormalities, which may have clinical repercussions in the patient. It is therefore necessary to identify those who could be candidates for neurosurgical intervention. The size of the pituitary gland is smaller in these patients, but this does not seem to be related to hormone deficiency and short stature or exposure to a low dose of total body irradiation.

Background Diabetic foot ulcers (DFUs) are a significant complication of diabetes mellitus and are often accompanied by various complications including hemolytic anemia. However, the clinical and hematological correlates of hemolytic anemia in patients with DFU remain poorly understood. This prospective observational study aimed to investigate the clinical and hematological correlates of hemolytic anemia in patients with DFU and to elucidate the potential mechanisms underlying this complication and its impact on wound healing. Methodology A total of 148 adult patients diagnosed with DFUs were enrolled in this study. Clinical and demographic data were collected, including age, sex, duration of diabetes, glycemic control status, presence of comorbidities, and foot ulcer characteristics. Hematological parameters, including complete blood counts, reticulocyte counts, and hemolysis markers, were measured at baseline and during the follow-up visits. Statistical analyses were conducted to assess the prevalence of hemolytic anemia, identify the demographic and clinical factors associated with its presence, and explore its relationship with wound healing outcomes. Results The prevalence of hemolytic anemia among patients with DFU was 41.9%. Patients with hemolytic anemia had a longer duration of diabetes (mean duration: 8.3 ± 2.1 years), higher glycated hemoglobin (HbA1c) levels (mean: 9.2% ± 1.5%), and a greater burden of comorbidities than those without hemolytic anemia. Hematological analysis revealed significant differences in hemoglobin levels, red blood cell indices (mean corpuscular volume: 89.6 ± 5.2 fL), and markers of hemolysis (mean lactate dehydrogenase level: 325 ± 45 U/L) between DFU patients with and without hemolytic anemia. Furthermore, correlations were observed between hematological parameters and wound healing outcomes, suggesting potential implications for clinical management. Conclusions This study provides valuable insights into the clinical and hematological correlates of hemolytic anemia in patients with DFU. These findings highlight the importance of recognizing and addressing hematological abnormalities in the management of DFU, with potential implications for optimizing wound healing and improving clinical outcomes.

Background: Sleeve gastrectomy has gained prominence in obesity treatment, yet it is not without complications, such as the development of anemia in the medium term. Given the high prevalence of Helicobacter pylori infection in Peru, it is imperative to explore its potential association with this postoperative complication. Objective: To evaluate the association between the presence of Helicobacter pylori and the development of anemia 12 months after sleeve gastrectomy. Methods: A retrospective cohort study was carried out based on an analysis of secondary data from a private clinic in Lima, Peru, which included two groups of people over 18 years of age who had undergone sleeve gastrectomy between 2010 and 2020. We considered the subjects who had the previous diagnosis of Helicobacter pylori as well as those who did not have the infection, according to the detection of the bacteria by endoscopy before surgery. Results: A total 313 individuals were analyzed, and it was found that the prevalence of Helicobacter pylori was 46.0% and the incidence of anemia 12 months after sleeve gastrectomy was 18.2%. The presence of Helicobacter pylori increased the risk of de novo anemia (Relative Risk = 1.56; 95% confidence intervals: 1.02-2.41; p = 0.043). When stratifying by sex, the association was maintained only for the male group (Relative Risk = 2.84; 95% confidence intervals: 1.02-7.02; p = 0.047). Conclusions: It was identified that the presence of Helicobacter pylori had a significant association with the development of de novo anemia, mainly in male subjects, 1 year after undergoing sleeve gastrectomy.

Management of acquired aplastic anemia (AA) in emerging countries depends on the means of prognostic stratification, treatment and logistics available. During the 13th annual harmonization workshop of the francophone Society of bone marrow transplantation and cellular therapy (SFGM-TC), a designated working group reviewed the literature in order to elaborate unified guidelines for allogeneic hematopoietic cell transplantation (Allo-HCT) in this disease. In terms of practice, the conclusions are as follows; The use of anti-tymocyte globuline (ATG) is mainly from rabbit and very little from horse. Access to bone marrow graft, total body irradiation, and the international unrelated donor registries is limited, which justifies the use of peripheral blood stem cells, chemotherapy-based conditioning, and related alternative donor. The workshop recommends matched sibling allo-HCT in all patients aged less than 40 years with acquired severe or very severe AA. For patients aged over than 40 years, or who lack an HLA-identical donor, treatment with the combination of cyclosporin, horse ATG, eltrombopag or cyclosporine, eltrombopag is recommended. If horse ATG and eltrombopag are not available, matched sibling allo-HCT may be indicated as first-line therapy in patients aged between 40-60 years, and good performance status. Although, in patients who have failed immunosuppressive treatments and thrombopoietin agonists, and in the absence of HLA-matched donor, a haplo-identical allo-HCT with modified Baltimore conditioning is recommended.

OBJECTIVE: To determine maternal and neonatal outcomes in individuals with iron deficiency receiving antepartum intravenous (IV) iron supplementation, stratified by the degree of anemia. STUDY DESIGN: Retrospective cohort study of iron-deficient pregnant patients who received at least one IV infusion of iron (iron sucrose, low molecular weight iron dextran [LMWID], or ferric carboxymaltose) during their pregnancy from January 1, 2011 through June 16, 2022. Our primary outcomes included both neonatal composite morbidity and maternal composite morbidity in the context of maternal anemia. RESULTS: Patients who received LMWID had fewer infusion visits, received higher total doses of iron and had a more substantial correction of hemoglobin compared to those who received iron sucrose (p < 0.01). Maternal anemia at the time of admission was not associated with neonatal composite morbidity. However, there was a significant association between anemia status and maternal composite outcome (p = 0.05). Anemia at time of delivery was associated with the likelihood of requiring a blood transfusion (p = 0.01). CONCLUSION: This study reinforces previous findings emphasizing the adverse effects of iron deficiency on maternal health and the role of IV iron in reducing these risks.

We investigated immune cytopenia in multiple myeloma (MM) patients with concurrent acquired aplastic anemia (AA), focusing on three clinical cases treated with plasma cell-directed therapy. All three patients achieved partial response in MM and one patient experienced complete resolution of AA. Two patients had partial improvement in transfusion requirement but continued to suffer from severe AA, leading to immunosuppressive therapy (IST) with improvement of transfusion requirement in both patients. In vitro serum testing of these patients demonstrated platelet mitochondrial dysfunction and platelet apoptosis but did not show sera-specific inhibition of erythroid colony formation in progenitor cells. The levels of IL8 and IL15 were elevated in MM patients with AA, implicating their potential roles in this co-occurrence. Response to IST points to the possibility of myeloma-dysregulated immune system leading to autoreactive T-cell destruction of hematopoietic stem and progenitor cells, offering insights for developing new treatment for cytopenia in MM.

Tuberculosis (TB) spreads through droplets that contain Mycobacterium tuberculosis (Mtb) and can infect susceptible people. Due to different risk factors, people have different susceptibility ranges towards TB. The risk factors are classified into three main groups, includ-ing bacterial, environmental, and host factors. Literature review reveals that the most important host risk factors are aging, male gender, genetics, epigenetics, having an impaired immune system, diabetes, malignancy, malnutrition, anemia, and pregnancy. The risk factors contribute to the increase in TB cases through inflammation, increased contact with TB patients, disrup-tion of immune genes, changes in gene expression, increased activity of Mtb, damage to cellu-lar immunity, reactivation of Latent TB Infection (LTBI), increased susceptibility to TB, com-promised immunity, and changes in the proportion of T cell subgroups, respectively. Therefore, identification of the infection source and high-risk people and timely treatment of the patients can reduce TB mortality and help control the disease.

Objective. To evaluate the evidence regarding the association between iron deficiency anemia (IDA) and dental caries in children and adolescents. Methods. Searches were conducted in 4 international databases from the beginning of records until October 2023. Studies evaluating the association between IDA and dental caries in individuals aged 6 months to 18 years were included. Risk of bias was assessed using the Newcastle Ottawa Scale. Quantitative synthesis was performed using the inverse variance or Mantel-Haenzel method, depending on the type of outcome analyzed. Measures of association included odds ratios and mean differences, employing a random-effects model with a 95% confidence interval. Results. A total of 1161 studies were identified, of which 12 were selected for qualitative review and 9 for meta-analysis. A significant association was found between IDA and dental caries (odds ratio of 3.54; 95% CI: 2.54-4.94) and a higher rate of dental caries in the presence of IDA (mean difference of 1.96; 95% CI: 1.07-2.85). The certainty of evidence according to GRADE was rated as very low. Conclusions. Despite the limited certainty, the findings indicate a significant association between IDA and dental caries. It is prudent to interpret these results with caution, considering the methodological limitations of the studies. However, given the potential relevance of this association for public health, recommending oral health strategies, including preventive and corrective dental interventions, for anemia control programs underlines the importance of more rigorous future research to strengthen the certainty of the evidence and guide the implementation of these strategies.

Objectives: Although lower hemoglobin levels associate with worse intracerebral hemorrhage (ICH) outcomes, causal drivers for this relationship remain unclear. We investigated the hypothesis that lower hemoglobin relates to increased hematoma expansion (HE) risk and poor outcomes using human observational data and assessed causal relationships using a translational murine model of anemia and ICH. Methods: ICH patients with baseline hemoglobin measurements and serial CT neuroimaging enrolled between 2010-2016 to a multicenter, prospective observational cohort study were studied. Patients with systemic evidence of coagulopathy were excluded. Separate regression models assessed relationships of baseline hemoglobin with HE (≥33% and/or ≥6mL growth) and poor long-term neurological outcomes (modified Rankin Scale 4-6) after adjusting for relevant covariates. Using a murine collagenase ICH model with serial neuroimaging in anemic vs. non-anemic C57/BL6 mice, intergroup differences in ICH lesion volume, ICH volume changes, and early mortality were assessed. Results: Among 1190 ICH patients analyzed, lower baseline hemoglobin levels associated with increased odds of HE (adjusted OR per -1g/dL hemoglobin decrement: 1.10 [1.02-1.19]) and poor 3-month clinical outcomes (adjusted OR per -1g/dL hemoglobin decrement: 1.11 [1.03-1.21]). Similar relationships were seen with poor 6 and 12-month outcomes. In our animal model, anemic mice had significantly greater ICH lesion expansion, final lesion volumes, and greater mortality, as compared to non-anemic mice. Conclusions: These results, in a human cohort and a mouse model, provide novel evidence suggesting that anemia has causal roles in HE and poor ICH outcomes. Additional studies are required to clarify whether correcting anemia can improve these outcomes.

Babesiosis, as a vector-borne infectious disease, remains relatively rare and is prone to being overlooked and misdiagnosed. Therefore, understanding the epidemiological characteristics and clinical manifestations of babesiosis is crucial for the prompt detection and treatment of the disease. We reported a 63-year-old male patient presenting with spontaneous fever and chills. Laboratory investigations revealed erythrocytopenia, reduced hemoglobin levels, and increased reticulocytes and total bilirubin. Bone marrow examination indicated vigorous cell proliferation, a decreased granulocyte to red cell ratio, and predominant erythroid cell proliferation, with a higher prevalence of intermediate and late-stage juvenile granulocyte and erythroid cells. Initial treatment focused on hemophagocytic syndrome triggered by Epstein-Barr virus infection yielded unsatisfactory results, leading to secondary multiple pulmonary infections. Metagenomic next-generation sequencing (mNGS) of sputum samples pointed to hemolytic anemia induced by Babesia infection, which was subsequently confirmed through peripheral blood smear analysis. The patient responded well to prompt administration of atovaquone and azithromycin, with symptoms resolving and laboratory parameters normalizing. Hemolytic anemia resulting from babesiosis should be distinguished from hemophagocytic syndrome caused by Epstein-Barr virus and other hematologic conditions. mNGS represents an efficient technique for Babesia detection.

BACKGROUND: There is currently no research on the correlation between novel inflammatory indexes systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and the risk of anemia in chronic kidney disease (CKD) population, as well as survival analysis in CKD with anemia. METHODS: This investigation encompassed 4444 adult subjects out of the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2018. The study utilized multi-variable logistic regression to assess the relationship between SII, NLR, PLR, and anemia risk occurrence in CKD population. Survival differences in CKD patients with anemia, based on varying levels of SII, NLR, and PLR were evaluated employing Kaplan-Meier and Cox proportional hazards models. RESULTS: The adjusted logistic regression model demonstrates that SII, NLR, and PLR are associated with the risk of anemia occurrence in CKD population. Kaplan-Meier's analysis reveals significant differences in survival rates among CKD patients with anemia stratified by NLR levels. The adjusted Cox proportional hazards model shows that the higher NLR group has a 30% elevated risk of all-cause mortality contrasted with lower group (hazard ratio, HR: 1.30, confidence interval (CI) [1.01, 1.66], p value <.04). Restricted cubic spline (RCS) demonstrates no nonlinear relationship between NLR and all-cause mortality. Lastly, sub-cohort analysis indicates that in populations with diabetes, hypertension, and hyperuricemia, NLR levels have a greater impact on all-cause mortality. CONCLUSIONS: Controlling inflammation may reduce the occurrence of anemia in CKD populations, with NLR serving to be a potential prognostic indicator for survival results within CKD patients suffering from co-morbid anemia.

BACKGROUND: Pernicious anemia (PA) is believed to be highly prevalent in Western countries but has rarely been reported in China. The study explores whether PA, an autoimmune disease, is an uncommon cause of cobalamin (vitamin B12) deficiency anemia in China. METHODS: Clinical and hematological data were collected from 90 cobalamin deficiency-caused megaloblastic anemia (MA) patients between July 2014 and December 2021. Through anti-intrinsic factor antibody (IFA) and anti-parietal cell antibody (PCA) testing, PA was distinguished from other causes of cobalamin deficiency leading to MA. Meanwhile, 30 healthy controls (HCs) were included to estimate the positive rates of IFA and PCA. RESULTS: Of the 30 HCs, only one tested positive for IFA, and all 30 tested negative for PCA. Among the 90 patients with cobalamin deficiency-caused MA, 76.7% were positive for IFA, and 47.8% were positive for PCA; a total of 76 patients (84.4%) were diagnosed with PA. The mean follow-up time was 41.0 ± 16.3 months. During the follow-up period, no case relapsed among the continuous cobalamin-supply treatment patients, while 24.4% of patients relapsed due to the interruption of maintenance cobalamin-supplement therapy (the median recurrence time was 54.0 ± 17.7 months). CONCLUSIONS: The proportion of PA in cobalamin deficiency-caused MA patients in Hainan province was higher than 80%, which was more common than expected. Therefore, screening for IFA, PCA, endoscopic biopsy, and thyroid-related parameters are recommended for all cobalamin deficiency-caused MA patients. Furthermore, maintenance cobalamin-supplement therapy is important for PA patients.
This research examines pernicious anemia (PA), a type of anemia caused by vitamin B12 deficiency, which has been widely reported in Western countries but is less known in China. The study focuses on determining if PA is also a significant cause of this deficiency in Hainan, China. Researchers gathered data from patients with megaloblastic anemia (a blood disorder) due to lack of vitamin B12, comparing them with healthy individuals to see how common PA is. The findings reveal that a very high percentage of the patients studied have PA, much higher than expected. This suggests that PA is not as rare in this region of China as previously thought. The study also highlights the importance of continuous treatment with vitamin B12 to prevent the recurrence of the anemia. Based on these results, the researchers recommend that all patients with vitamin B12 deficiency should be tested for PA and continuously receive vitamin B12 supplements to maintain their health once diagnosed with PA. This strategic insight is of paramount importance to medical practitioners in China, potentially paving the way for enhanced clinical management protocols for individuals afflicted by this ailment.

Ghosal hematodiaphyseal dysplasia (GHDD) is a rare autosomal recessive disorder characterized by increased bone density involving diaphyses of long bones and defective hematopoiesis. It is due to biallelic variants in the TBXAS1 (OMIM*274180) gene, which encodes for thromboxane synthase. We present a rare case of a middle-aged woman who presented with chronic anemia and bone pain. About 31-year-old Southeast Asian female with a history of persistent iron deficiency anemia (6.1 gm/dL) presents with bilateral knee pain for 4 years. Autoimmune panel turned out to be negative. CT scan of the lower limbs showed multilamellated endosteal thickening specifically involving diaphyses with severe narrowing of medullary canal. PET CT scan revealed tubular remodeling, intramedullary ground glass matrix, and mild cortical thickening with increased FDG uptake in diaphyseal regions of femur and tibia. Bone marrow biopsy of left tibia revealed fibrocellular marrow with dyserythropoiesis. Considering the slow progression of illness over 4 years and radiological evidence suggestive of bone remodeling with severe narrowing of medullary canal as the cause of anemia, the patient underwent molecular analysis for GHDD. Results revealed homozygous p.Arg412Gln (exon 11) in TBXAS1 gene. Considering the effect of NSAIDs on cyclooxygenase and its downstream metabolites, oral Aspirin 150 mg/day was initiated. Hemoglobin improved to 11 gm/dL at 3-month follow-up visit. The complexity of reaching a diagnosis of GHDD underscores the importance of maintaining a high clinical suspicion and thorough analysis of radiological evidence. The treatment for GHDD involves aspirin, a readily available drug.
