Sacubitril/valsartan reduces incident anaemia and iron therapy utilization in heart failure: The PARAGON-HF trial.

AIMS: Renin-angiotensin system inhibitors (RASi) have been shown to lower haemoglobin levels, potentially related to reductions in erythropoietin levels and haematopoiesis. We examined whether sacubitril/valsartan might attenuate this effect of RASi alone on incident anaemia in patients with heart failure (HF) with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF). METHODS AND RESULTS: PARAGON-HF was a global, multicentre randomized clinical trial of sacubitril/valsartan versus the RASi valsartan in patients with HF and left ventricular ejection fraction ≥45%. We evaluated haemoglobin trajectory and risks of incident anaemia and new iron therapy initiation during follow-up. Among 4795 participants, 1111 (23.2%) had anaemia at randomization and 5.6% were treated with iron at baseline. Over a median follow-up of 2.9 years, patients with anaemia were at significantly higher risk for total HF hospitalizations and cardiovascular death, compared with those without anaemia (21.6 vs. 11.5 per 100 patient-years; adjusted rate ratio 1.31; 95% confidence interval [CI] 1.12-1.54; p = 0.001). Sacubitril/valsartan slightly slowed the decline in haemoglobin levels by 0.1 g/dl (95% CI 0.0-0.2 g/dl; p = 0.005). Participants treated with sacubitril/valsartan were at significantly lower risk of developing anaemia (30.3% vs. 37.6%; hazard ratio [HR] 0.76; 95% CI 0.68-0.85; p < 0.001) and starting iron therapy (8.1% vs. 10.0%; HR 0.81; 95% CI 0.67-0.97; p = 0.026). Treatment effects of sacubitril/valsartan versus valsartan on total HF hospitalizations and cardiovascular death were consistent among patients across the haemoglobin spectrum (pinteraction = 0.60). CONCLUSIONS: Among patients with HFmrEF/HFpEF, treatment with sacubitril/valsartan resulted in modestly smaller declines in haemoglobin, lower rates of incident anaemia, and fewer new initiations of iron therapy compared with RASi.

Multidisciplinary approaches to study anaemia with special mention on aplastic anaemia (Review).

Anaemia is a common health problem worldwide that disproportionately affects vulnerable groups, such as children and expectant mothers. It has a variety of underlying causes, some of which are genetic. A comprehensive strategy combining physical examination, laboratory testing (for example, a complete blood count), and molecular tools for accurate identification is required for diagnosis. With nearly 400 varieties of anaemia, accurate diagnosis remains a challenging task. Red blood cell abnormalities are largely caused by genetic factors, which means that a thorough understanding requires interpretation at the molecular level. As a result, precision medicine has become a key paradigm, utilising artificial intelligence (AI) techniques, such as deep learning and machine learning, to improve prognostic evaluation, treatment prediction, and diagnostic accuracy. Furthermore, exploring the immunomodulatory role of vitamin D along with biomarker­based molecular techniques offers promising avenues for insight into anaemia's pathophysiology. The intricacy of aplastic anaemia makes it particularly noteworthy as a topic deserving of concentrated molecular research. Given the complexity of anaemia, an integrated strategy integrating clinical, laboratory, molecular, and AI techniques shows a great deal of promise. Such an approach holds promise for enhancing global anaemia management options in addition to advancing our understanding of the illness.

The effect of dates and honey extracts (phoenix dactylifera and apis mellifera) for increasing pregnant women's haemoglobin.

Objectives: To examine the effect of date fruit extract and honey in increasing haemoglobin levels in pregnant women. METHODS: The quasi-experimental study was conducted from July to August 2022 in Rumbai Pesisir Subdistric, Pekanbaru, Indonesia, and comprised anaemic pregnant women with haemoglobin levels <11gm/dl who were not consuming iron tablets or blood boosters. They were given honey and date extracts 2 tablespoons twice daily for two weeks. Haemoglobin level was checked at baseline and then at the end of each week of intervention. Data was analysed using SPSS version 20 and quantitative method by using bivariate analysis. RESULTS: Of the 50 women, 59(98%) were aged 20-35 years, and 1(2%) was aged >35 years. Besides, 21(42%) women were in the second trimester, 17(34%) in third, and 12(24%) in the first trimester of pregnancy. The increase in haemoglobin levels post-intervention was highly significant (p=0.0001). CONCLUSIONS: Date fruit extract and honey increased haemoglobin level of pregnant women.

nutritional fulfillment for anaemia prevention in female adolescents: Perceived benefits, barriers and commitment.

Objective: To identify the correlation of preventive nutrition for anaemia with perceived benefits, perceived barriers and commitment among young females. METHODS: The correlational, cross-sectional study was conducted from June to July 2022 in Surabaya, East Java, Indonesia, and comprised young females. The independent variables were perceived benefits, perceived barriers, and commitment. The dependent variable was preventive nutrition for anaemia. Data was collected online using Google Form. Data was analysed using a software SPSS version 23. RESULTS: There were 112 females with mean age 19.63±1.501 years. There were 101(90.2%) aged 18-24 years, and 100(89.3%) were in senior high school. Perceived benefits (p=0.021; r=0.218), perceived barriers (p=0.002; r=-0.286) and commitment (p=0.000; r=0.345) had a significant relationship with preventive nutrition for anaemia. Conclusion: Perceived benefits and high commitment to increase preventive nutrition against anaemia was seen in female adolescents. However, high perceived barrier could suppress their preventive nutrition.

The Importance of Molecular Biological Analysis for the Laboratory Diagnostic of Homozygous Haemoglobin Malay.

Haemoglobin (Hb) Malay is variant haemoglobin with a ß++ thalassemia phenotype. The prevalence of Hb Malay in the Malaysian population was 5.5%. We describe a 58-year-old male who presented with symptomatic anaemia to the Hospital Universiti Sains Malaysia. Further history revealed that the patient had anaemia since the age of 28, and on regular follow-up at other hospital. Physical examination revealed pallor, jaundice and hepatosplenomegaly. The full blood count and peripheral blood smear showed hypochromic microcytic anaemia with anisopoikilocytosis, and many target cells. High-performance liquid chromatography results showed a ß thalassemia trait. However, the diagnosis does not alight with the patient's condition. Bone marrow aspirate was completed and showed reactive changes and erythroid hyperplasia. A molecular test was then performed for ß globin gene mutation detection using Multiplex Amplification Refractory Mutation System (M-ARMS) PCR method. This revealed the result as homozygous codon 19 mutation or Hb Malay. Therefore, in this case report we would like to highlight the laboratory approaches, the challenges faced by the usual haematological investigations and the importance role of molecular testing in the diagnosis of severe anaemia.

Comparison of the efficacy and adverse effects of oral ferrous succinate tablets and intravenous iron sucrose: a retrospective study.

OBJECTIVE: To analyse the clinical efficacy and adverse drug reactions (ADRs) of iron preparations. METHODS: A total of 374 patients with iron deficiency anaemia admitted to our hospital between 1 January and 31 December 2020 were included in this study. They were divided into 2 groups based on their medication regimens: Group A (n = 187) took oral ferrous succinate tablets, and Group B (n = 187) received intravenous iron sucrose. The remission of major symptoms, laboratory test results, ADRs and other related data were collected after 4 weeks of treatment. RESULTS: Compared with the pre-treatment baseline, haemoglobin (Hb), serum iron (SI), serum ferritin (SF) and the mean corpuscular volume (MCV) increased in both groups at 4 weeks of treatment (P < 0.05). After treatment, Group A had lower levels of Hb (108.41 ± 8.39 vs. 122.31 ± 6.04 g/L, t = 6.293, P < 0.001), SI (9.72 ± 4.24 vs. 15.62 ± 5.41 µmol/L, t = 5.482, P < 0.001) and SF (27.1 ± 10.82 vs. 39.82 ± 10.44 ug/L, t = 6.793, P < 0.001) compared with Group B. In contrast, there was no significant difference in the post-treatment level of MCV (P > 0.05). The overall response rate significantly differed between the 2 groups (78.61% vs. 90.91%, χ2 = 10.949, P < 0.001). The incidence of ADRs of both groups were similar, and the difference was not statistically significant (χ2 = 0.035, P = 0.851). CONCLUSION: Iron sucrose demonstrates favourable efficacy and safety in treating iron deficiency anaemia.

The prevalence of anaemia in rural adolescent girls - A cross-sectional study to understand the sociodemographic and dietary determinants in Dharwad District, India.

Context: Anaemia is one leading cause of morbidity among adolescent girls. Prevention, early detection, and treatment can break the intergeneration cycle of malnutrition. Aims/Objectives: The aim of the study was to estimate the prevalence of anaemia and assess its sociodemographic determinants and understand its association with the dietary pattern of rural adolescent girls. Settings and Design: A cross-sectional study was conducted among 350 adolescent girls studying in the school of Kalgatigi Taluk, Dharwad district. The school girls were interviewed using a predesigned structured questionnaire by interview method. A food frequency questionnaire was used to assess the dietary pattern. Haemoglobin levels were estimated using Sahli's method. Statistical Analysis Used: Data were entered in Microsoft Excel and analysed using SPSS version 19 and the Chi-square test was applied to study the significance. Results: Rural adolescent school girls between the age group of 13-16 years were included. The prevalence of anaemia among them was found to be 47.4% and was significantly associated with the educational status of the mother, their socioeconomic status (SES), and type of diet. Vegetarian girls had a higher prevalence of anaemia. The frequency of meat and egg consumption was significantly associated with anaemia. The prevalence of anaemia was higher in thin and severely thin girls based on WHO-BMI. Conclusions: Anaemia in rural adolescent girls is of high burden and public health importance with a prevalence of 47.4% and significant association with dietary habits, SES, and BMI.

Incidence and risk factors of anaemia among people on antiretroviral therapy in Harare.

Background: Anaemia is associated with reduced quality of life and increased mortality risk among people living with HIV (PLHIV). Although antiretroviral therapy (ART) reduces the prevalence of anaemia, some patients remain at risk after commencing ART. Objectives: We estimated the incidence of anaemia after ART commencement and identified associated risk factors. Method: We analysed outpatient records at Newlands Clinic, Harare, Zimbabwe. Patients (≥ 5 years old) who were commenced on ART between January 2016 and December 2020 were included and were followed up for up to 2 years. Patients with anaemia at ART commencement and women who were pregnant at any time during follow-up were excluded. Cox proportional hazards regression was used to assess independent risk factors for anaemia. Results: During the study, 1110 patients ≥ 5 years old were commenced on ART with a prevalence of anaemia of 40.0%. Five hundred and twenty-nine patients met the inclusion criteria and were followed up for 823.7 person-years. The median age was 36.1 years and 290 (58.4%) were female. The incidence rate of anaemia after ART commencement was 176.1 per 1000 person-years (95% confidence interval [CI]: 149.6-207.2). Females (aHR: 2.09; 95% CI: 1.46-3.00, P < 0.001), zidovudine use (aHR: 3.50 96% CI: 2.14-5.71, P < 0.001), age 5-12 years or > 50 years, and the presence of World Health Organization stage III/IV disease (aHR: 2.19; 95% CI: 1.14-5.71, P = 0.019) had higher odds of developing anaemia. Conclusion: The incidence of anaemia after ART commencement was high. Female sex, zidovudine use, age and the presence of stage III/IV disease were independent risk factors for anaemia. Clinicians should screen PLHIV on ART regularly for anaemia.

Unveiling the prevalence of anaemia and its predictors among adults on highly active antiretroviral therapy in the dolutegravir era: a retrospective cross-sectional study.

OBJECTIVE: This study examined the prevalence, severity and risk factors of anaemia among adult people living with HIV attending an antiretroviral therapy centre in Woreta Primary Hospital, Woreta town, Ethiopia. DESIGN: Hospital-based retrospective cross-sectional study. SETTING: Public health facility that provides HIV care in Woreta town. PARTICIPANTS: A total of 289 medical records of adults living with HIV/AIDS on highly active antiretroviral therapy from February 2019 to September 2023 at government hospital were reviewed using a systematic sampling method. The data were entered using Epi-info V.7 and exported to SPSS V.23 for data analysis. The data were analysed using bivariate and then multivariate logistic regression models in order to identify variables associated with anaemia. At the 95% CI level, variables having a p value of <0.05 were deemed to be statistically significant predictors. PRIMARY OUTCOME: Prevalence and severity of anaemia and its predictors among adult patients living with HIV on antiretroviral therapy in Woreta Primary Hospital. RESULTS: The total prevalence of anaemia was 31.5% (95% CI 28.9 to 33.8). The prevalence of mild, moderate and severe anaemia was 20.42%, 10.38% and 0.70%, respectively. Predictors independently linked with anaemia were female sex (adjusted OR (AOR) 1.08), age ≥40 years (AOR 1.21), lived with HIV >10 years (AOR 2.31), CD4 counts <200 cells/µL (AOR 3.81), non-suppressed viral load (AOR 1.28), history of opportunistic infections (AOR 1.54), WHO clinical stages III and IV (AOR 1.37 and 2.23, respectively) and history of parasitic infestation (AOR 2.81). CONCLUSIONS: A sizeable proportion of participants were found anaemic. Female sex, older age, longer periods lived with the virus, lower CD4 count, non-suppressed viral load, history of opportunistic infections, WHO clinical stages III and IV and history of parasitic infestation were the contributing factors. Therefore, to improve the anaemic status and living circumstances of patients living with HIV, immediate action on the linked factors is needed, such as monitoring for maintenance of CD4 counts >200 cells/µL and avoiding progression of HIV to the advanced WHO clinical stages, suppressed viral load, preventing opportunistic infections and parasitic infestation.

Perceived barriers and opportunities for the introduction of post-discharge malaria chemoprevention (PDMC) in five sub-Saharan countries: a qualitative survey amongst malaria key stakeholders.

BACKGROUND: Post-discharge malaria chemoprevention (PDMC) is an intervention aimed at reducing morbidity and mortality in patients hospitalized with severe anaemia, with its effectiveness established in several clinical trials. The aim of this study was to better understand factors that would influence the scale up of this intervention, and to identify preferences for two delivery mechanisms, facility-based or community-based. METHODS: Forty-six qualitative individual interviews were conducted in five sub-Saharan countries amongst malaria key opinion leaders and national decision makers. Findings were analysed following a thematic inductive approach. RESULTS: Half of participants were familiar with PDMC, with a satisfactory understanding of the intervention. Although PDMC was perceived as beneficial by most respondents, there was some unclarity on the target population. Both delivery approaches were perceived as valuable and potentially complementary. From an adoption perspective, relevant evidence generation, favorable policy environment, and committed funding were identified as key elements for the scale up of PDMC. CONCLUSIONS: The findings suggest that although PDMC was perceived as a relevant tool to prevent malaria, further clarification was needed in terms of the relevant patient population, delivery mechanisms, and more evidence should be generated from implementation research to ensure policy adoption and funding.

A Spongy Appetite: A Case of Pica.

Pica is an eating disorder defined as the compulsive and repeated ingestion of substances that have no nutritional value for at least one month. This condition may be hard to diagnose without complications, as a high degree of suspicion is needed. The subject in this case was a teenager who presented with asthenia and unspecific abdominal pain. The etiological workup showed no abnormalities other than mild anemia and iron and folate deficiencies. After a thorough anamnesis, the patient's mother mentioned sporadic ingestion of synthetic mattress foam since childhood, which had become more frequent in the previous year. With this key information, it was possible to establish a diagnosis before serious complications occurred and thus help the patient get the necessary assistance by referring them to pediatrics, nutrition, and child and adolescent psychiatry consultations. This case report highlights the importance of a detailed anamnesis, particularly when dealing with unspecific symptoms, exploring the possibility of disorders that are rarely thought of, such as pica. It also recaps how important it is to address sensitive topics like eating disorders and create an open environment with no judgment, as these attitudes are crucial to ensuring the correct diagnosis and providing the best care for patients.

Mycophenolate Mofetil for the Treatment of Warm Autoimmune Haemolytic Anaemia Post-Rituximab Therapy: A Case Series.

Background: Warm autoimmune haemolytic anaemia (wAIHA) is an acquired haemolytic disorder most commonly treated with a combination of corticosteroids, rituximab and/or splenectomy. Third-line therapies for refractory cases include immunosuppressive agents. Mycophenolate mofetil is frequently used in these scenarios, although its use is supported by small studies and anecdotal evidence rather than large-scale data. Case description: We describe three cases of refractory warm autoimmune haemolytic anaemia successfully treated with mycophenolate mofetil. Case 1: A persistent case of autoimmune haemolytic anaemia in a 56-year-old was ultimately managed with mycophenolate mofetil, leading to successful steroid tapering and stable haemoglobin levels without relapse. Case 2: A woman with a complex oncological history, including lymphoma and breast cancer, achieved remission with mycophenolate therapy, maintaining stability post-steroid treatment. Case 3: Mycophenolate proved effective for a 63-year-old with cirrhosis after recurrent autoimmune anaemia and deep vein thrombosis, enabling cessation of steroids and maintaining remission. Conclusion: Management of this condition can be challenging and balancing the available treatments is crucial to reduce potential complications from long-term therapies that appear to be ineffective. Our case series demonstrates anecdotal experience on successful use of mycophenolate mofetil for complex refractory cases of wAIHA. LEARNING POINTS: Warm autoimmune haemolytic anaemia can be a challenging condition to manage. Refractory cases that are steroid-dependent can benefit from trialling steroid-sparing agents such as mycophenolate.Anti-CD20 agents such as rituximab can be very effective in refractory cases, however there is a small percentage of patients that might not be responsive to this monoclonal antibody.Autoimmune haemolytic anaemias can be frequently complicated by thrombotic events, and part of the backbone treatment is establishing good thromboprophylaxis.

An Unusual Case of HHV-8 Negative, Idiopathic, Multicentric Castleman Disease Following Chronic Lymphocytic Leukaemia.

Background: Castleman disease is a rare condition characterised by polytypic lymphocytes proliferation and lymphadenopathy generally with a benign course. Whereas high grade lymphoma (Richter syndrome) is a classical complication seen in chronic lymphocytic leukaemia with a poor outcome, benign conditions mimicking this entity are infrequent. Case description: We describe the case of an 81-year-old Caucasian male who developed a human herpesvirus-8 (HHV-8)-negative, idiopathic multicentric Castleman disease (iMCD) following a treated Binet C chronic lymphocytic leukaemia (CLL). The clinical and radiological pattern raised initially the suspicion of a classical Richter transformation. Blood analysis showed auto-immune haemolytic anaemia and thrombocytopenia. He had normal immunoglobulin levels. The anatomopathological analysis of a cervical adenomegaly showed hypervascularisation and a polytypic plasmocytic proliferation compatible with a plasmocytic iMCD type. Interestingly, bone marrow examination showed reticuline fibrosis but, in the absence of anasarca or generalised oedema, we were not allowed to conclude to the diagnosis of a TAFRO syndrome. We excluded all other mimicking conditions, comprising haematological malignancies, infections, and auto-immune diseases He was first treated with corticosteroids with poor results but dramatically responded to tocilizumab (anti-Il6). Conclusion: To our knowledge, this the first case described of a Castleman disease following CLL and surprisingly mimicking Richter syndrome. Clinicians should be aware of this rare misleading condition. LEARNING POINTS: Castleman disease can mimic a Richter transformation in a CLL patient.

One Haemolytic Anaemia May Hide Another: Paroxysmal Nocturnal Haemoglobinuria Masquerading As Plasmodium Falciparum Infection.

Background: Paroxysmal nocturnal haemoglobinuria (PNH) is a rare, genetic and acquired haematologic disease that causes complement-mediated intravascular haemolytic anaemia, thrombosis and bone marrow failure. Case description: A 27-year-old migrant patient attended the emergency department in a context of fever and chills over the previous few days as well as chronic fatigue, dyspnoea and chest pain. His medical history included chronic anaemia and erectile dysfunction. Initial biology showed a haemoglobin of 6.3 g/dl, platelets of 25,000/µl, total leucocytes of 3,500/µl with 1,500 neutrophils. B12 vitamin, folic acid, ferritin and thyroid stimulating hormone were normal. Lactate dehydrogenase levels were high and haptoglobin was non-measurable. C-reactive protein was 46.1 mg/l. A thick blood smear revealed Plasmodium falciparum infection with 0.1% parasitaemia. The patient was treated with an oral combination of artemether and lumefantrine. Three weeks later, the patient consulted the infectious disease department given the lack of clinical improvement. The cytopenias worsened, and lactate dehydrogenase (LDH) and reticulocytes increased. Tests for schistocytes, a thick blood smear for malaria and a direct Coombs test were negative; a myelogram was reassuring. An abdominal, pelvic and thoracic CT scan showed a mild hepatomegaly with no focal lesion and no splenomegaly or adenomegaly. A 12-colour flow cytometry unveiled a PNH clone on 90.9545% of neutrophils and 80.7371% of monocytes. Discussion: PNH patients can be vulnerable to parasites infection (such as P. falciparum) as it may trigger breakthrough haemolysis through uncontrolled resurgence of activity of the complement system. In our patient, P. falciparum infection was a confounding factor, as it commonly causes haemolytic anaemia and thrombocytopenia, and patients living in malaria-endemic regions can carry low parasitaemia while being slightly symptomatic or asymptomatic. LEARNING POINTS: Plasmodium falciparum infection can cause breakthrough haemolysis in patients with paroxysmal nocturnal haemoglobinuria.Low P. falciparum parasitemia in patients living in malaria-endemic regions is not always significant as these patients often carry acquired immunity.Patients from malaria-endemic regions presenting with severe sickness and low P. falciparum parasitemia must be assessed for other diseases, as it cannot explain heavy illness.Patients presenting with haemolytic anaemia, no schistocytes, a negative direct Coombs test and other unexplained cytopenia such as thrombocytopenia/neutropenia and other unexplained clinical manifestations such as dyspnoea, chest pain or erectile dysfunction should be assessed for paroxysmal nocturnal haemoglobinuria.

Association of biomarkers of endothelial function, coagulation activation and kidney injury with persistent albuminuria in sickle cell anaemia.

Persistent albuminuria (PA) is common in sickle cell anaemia (SCA). With the association of chronic kidney disease (CKD) with increased mortality, biomarkers that predict its development or progression are needed. We evaluated the association of select biomarkers with PA in adults with SCA using Kruskal-Wallis rank-sum test and logistic regression models, with adjustment for multiple testing. Of 280 subjects, 100 (35.7%) had PA. Median plasma levels of soluble vascular cell adhesion molecule-1 (VCAM-1) (1176.3 vs. 953.4 ng/mL, false discovery rate [FDR] q-value <0.003), thrombin-antithrombin complex (5.5 vs. 4.7 ng/mL, FDR q-value = 0.04), and urinary angiotensinogen (AGT) (12.2 vs. 5.3 ng/mg, FDR q-value <0.003), urinary nephrin (30.6 vs. 27.2 ng/mg, FDR q-value = 0.04), and urinary kidney injury molecule-1 (KIM-1) (0.8 vs. 0.5 ng/mg, FDR q-value <0.003), normalized to urine creatinine, were significantly higher in subjects with PA. In multivariable analysis, only urinary AGT (odds ratio = 1.058, FDR q-value <0.0001) remained a significant predictor of PA. In addition, soluble VCAM-1 (FDR q-value <0.0001), D-dimer (FDR q-value <0.0001), urinary AGT (FDR q-value <0.0001), KIM-1 (FDR q-value <0.0001), and nephrin (FDR q-value <0.0001) were significantly associated with urine albumin-creatinine ratio in multivariable analyses. Longitudinal studies to evaluate the predictive capacity of biomarkers for the development and progression of CKD in SCA are warranted.

A cross-sectional study of the relationship between iron deficiency anaemia and chronic pain.

Iron deficiency and iron deficiency anaemia are frequently under-recognised in chronic conditions with non-specific symptoms, including fatigue. This study aimed to assess the prevalence of iron deficiency with or without anaemia in chronic pain patients, and the association between iron deficiency status, fatigue and health-related quality of life. Eighty-two patients attending chronic pain outpatient appointments were recruited into this cross-sectional study. Iron studies and haemoglobin were determined from venous blood samples. Participants' health-related quality of life was assessed with the 36-item short form survey and fatigue with the functional assessment of chronic illness therapy fatigue scale. Iron deficiency was prevalent in 58.8% of patients and 2.5% met the criteria for iron deficiency anaemia. There was no significant association between iron deficiency status and the functional assessment of chronic illness therapy fatigue scale score or 36-item short form survey domain scores. There was a high prevalence of iron deficiency in this group of chronic pain patients, while the prevalence of iron deficiency anaemia was low. There was no statistically significant association found between iron deficiency status and fatigue or quality of life measures.

A clinical audit of red blood cell transfusion practices at a district hospital in South Africa.

BACKGROUND:  Red blood cell (RBC) transfusion is one of the most critical and expensive lifesaving treatment modalities. A clinical audit is a valuable instrument to determine whether transfusion practices align with the guidelines and identify knowledge deficiencies. The study aimed to evaluate the RBC transfusion practices and patient outcomes at the National District Hospital in Bloemfontein, South Africa, and to determine adherence to transfusion guidelines. METHODS:  A retrospective descriptive study was conducted. All blood transfusion registers in the hospital were used to identify transfusion episodes during the study period. Files were retrieved from the admissions office and information captured on a paper-based datasheet. The appropriateness of the transfusion and adherence to the South African transfusion guidelines were evaluated using specific criteria. RESULTS:  Of the 118 transfusion episodes during the study period, 78 files were retrieved and 76 included in the study. The patients' median age was 47 years (interquartile range [IQR]: 32-66 years), with human immunodeficiency viruses (HIV) (n = 34; 44.7%) being the most common comorbid condition. Pre-transfusion haemoglobin was documented for all patients with a median of 4.6 g/dL (IQR: 3.95 g/dL - 5.5 g/dL). The audit revealed that in 68.4% (n = 52) of the cases, the guidelines were applied appropriately. CONCLUSION:  The study described the blood transfusion practices and identified shortcomings when compared with the standard clinical guidelines.Contribution: The study highlights the importance of applying rationale, caution and consideration of the specific patient profile when performing transfusions.

Fanconi Anaemia associated with café au lait spots: A rare case report.

Fanconi Anaemia is an autosomal recessive disorder, which is characterised by progressive pancytopenia, café au lait spots (>50%), bruising, petechie, recurrent infections, short height (50%), and thumb and radial bone anomalies (40%). Herein, is presented a case of a lean emaciated female child, who presented with the chief complaints of fever, loose stools and decreased appetite for one month reported at Sindh Government General Hospital, Karachi, on February, 1, 2023. She had cutaneous findings of hyperpigmentation and café au lait spots and a tri-phalangeal thumb. On investigation, pancytopenia and a low reticulocyte count of 0.7% was also observed. Karyotype and chromosomal breakage test induced by Diepoxybutane confirmed her as a case of Fanconi Anaemia.

Prevalence and severity of anaemia among the Temiar sub-ethnic indigenous Orang Asli communities in Kelantan, Peninsular Malaysia.

Introduction: Anaemia remains a primary concern of public health in developing countries. Indigenous populations are a significant and frequently underreported group at risk for anaemia. This study aimed to assess the prevalence of anaemia and identify its determinants in the Temiar sub-ethnic indigenous Orang Asli (OA) community in Peninsular Malaysia. Methodology: A community-based cross-sectional study was conducted among 640 indigenous Temiar OA participants from a remote settlement in Gua Musang, Kelantan, Malaysia. Data was collected using face-to-face interviews with a standardised pretested questionnaire and through blood samples collected for haemoglobin (Hb) testing. Anaemia status was determined using the Hb level cut-off established by the World Health Organization (WHO). Descriptive analysis was used to determine the prevalence of anaemia, while multiple logistic regression was used to determine factors associated with anaemia. Results: The overall anaemia prevalence was 44.7% (286/640), and the prevalence rates of mild, moderate and severe anaemia were 42.7, 50.7 and 6.6%, respectively. Anaemia-specific prevalence varied significantly by age group (p < 0.001) and was highest in the ≤5 group for both moderate anaemia (43.4%) and severe (42.1%), followed by the 6-17 age group for mild anaemia (39.3%). The prevalence of anaemia was also highest among students (53.9%), with a significant difference observed between the three anaemia severity classifications (p = 0.002). In the multivariate logistic regression, only age groups of 6-17 (adjusted odds ratio [aOR] 0.38, p < 0.001), 18-40 (aOR 0.18, p < 0.001) and > 40 (aOR 0.25, p < 0.001) were significantly associated with the lower odds of anaemia in the population. Conclusion: This study has highlighted the high prevalence of anaemia among indigenous OA in Peninsular Malaysia and revealed that younger children were positively associated with childhood anaemia. Effective interventions and special attention to this indigenous population need to be implemented to reduce the risk of anaemia.

A retrospective analysis of haematological side effects of olaparib in excess-weight and normal BMI patients with ovarian cancer.

Background: Olaparib is the first poly(ADP-ribose) polymerase inhibitor approved in Europe for the treatment of platinum-sensitive patients with newly diagnosed or recurrent platinum-sensitive ovarian cancer with a confirmed BRCA mutation or homologous recombination deficiency (HRD). Epidemiological studies have shown an incompatible association between ovarian cancer and obesity, but there have also been scientific reports indicating that obesity, especially severe obesity, increases the risk of ovarian cancer. Olaparib has a wide range of side effects, especially anaemia and neutropenia, which may lead to dose reduction or therapy discontinuation. Therefore, therapeutic drug monitoring (TDM) is recommended. The aim of the study was a retrospective analysis of threshold value of the trough concentration of olaparib (Ctrough) and haematological adverse reactions after olaparib treatment (300 mg/12 h) in excess-weight and normal body mass index (BMI) patients with ovarian cancer. Materials and methods: The pilot study was conducted on 38 ovarian cancer patients who were divided into two groups: I - normal BMI patients (BMI = 18.5-24.9 kg/m2; n = 14), II - excess-weight patients, i.e. overweight and obese patients (BMI ≥ 25 kg/m2; n = 24). The severity of neutropenia and anaemia was graded according to the Common Terminology Criteria for Adverse Events (CTCAE v5.0). The values of the mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), and red blood cell distribution width (RDW) parameters were also taken into account. HPLC-UV method (λ = 254 nm) was applied to measure olaparib plasma concentrations. Results: There were no statistically significant differences in olaparib Ctrough between the groups - 1602.86 vs. 1567.40 ng/mL (p = 0.9156). However, the overweight and obese patients had slightly higher dose/kg-adjusted olaparib Ctrough - 204.17 vs. 159.32 ng/mL/mg/kg. The incidence of grade 1 anaemia in the groups was as follows: I - 42.86%, II - 41.67%. Grade 2 and 3 anaemia was observed only in group II - 4.17% and 8.33%, respectively. The incidence of neutropenia in the groups of patients was as follows: grade 1: group I - 21.43%, group II - 20.83%; grade 2: group I - 7.14%, group II - 4.17%. Conclusions: The incidence of haematological adverse reactions to olaparib, such as neutropenia and grade 1 anaemia in the group of overweight and obese patients was the same as in the normal BMI group. The overweight and obese patients were characterised by higher severity of haematological adverse reactions to olaparib and slightly higher dose/kg-adjusted olaparib Ctrough. After one month of treatment with olaparib the overweight and obese patients had significantly lower red blood cells (RBC) and haemoglobin (Hgb) levels than the patients with normal BMI, which may indicate that anaemia develops faster in this group of patients.
