Spur cell anemia related to alcoholic liver cirrhosis managed without liver transplantation: a case report and literature review

Exploring Haematological Complications in Cirrhosis of the Liver: A Comprehensive Review

Various chronic liver diseases inevitably end up with cirrhosis of the liver, and this comes with a whole range of haematological complications. Therefore, this detailed review has discussed pathophysiology, clinical manifestations, diagnostic measures, and treatment plans for these anomalies. Closely related are conditions such as anaemia, thrombocytopenia, coagulopathy, leukopenia, and haemolytic disorders, which are known to contribute to morbidity and mortality in cirrhotic patients significantly. Therefore, we need to understand the causes of these problems to find ways of helping our patients better. For this reason, multidisciplinary management will be key in ensuring proper monitoring, timely intervention, and preventive measures for haematological abnormalities in cirrhosis. Additionally, there have been tremendous advancements in therapeutic options, like adjunctive therapies or haematopoietic growth factors, which hold much promise regarding patient outcomes. This article emphasizes the proactive management of haematological complications associated with cirrhosis while highlighting the need for further research coupled with collaboration aimed at strengthening prevention strategies, diagnostic methods, and curative interventions.

Red cell abnormalities characterized by ektacytometry in children with cholestasis

BACKGROUND

Spur-cell anemia sometimes accompanies cholestasis. We postulated that even in the absence of spur-cells, cholestasis might alter red blood cell (RBC) osmotic fragility and deformability. Therefore, we assessed these RBC measures by ektacytometry in pediatric patients.

METHODS

We conducted a single center, prospective, cross-sectional investigation of RBC membrane characteristics by ektacytometry in pediatric patients with intra- and extrahepatic cholestasis followed at Cincinnati Children's Hospital Medical Center. We measured red cell membrane fragility and deformability in 17 patients with cholestasis and 17 age-matched controls without cholestasis.

RESULTS

Patients with cholestasis had decreased RBC osmotic fragility compared to controls, with a significant left shift in Omin, indicating increased RBC surface-to-volume ratio. One showed spur cell morphology. However, the other 16 had no spurring, indicating that ektacytometry is a sensitive method to detect RBC membrane abnormalities. Left shift of Omin positively correlated with serum conjugated bilirubin levels and even more negatively with serum vitamin E concentration.

CONCLUSIONS

This study suggests that subclinical red blood cell membrane abnormalities exist in most pediatric patients with cholestasis, increasing risk for hemolysis when subjected to oxidative stress. Hence minimizing pro-oxidants exposure and maximizing antioxidant exposure is advisable for this group.

IMPACT

Spur cell anemia due to decreased red cell osmotic fragility and decreased deformability has been reported among patients with cholestasis. Ektacytometry is a reliable, reproducible method to measure red cell osmotic fragility and deformability. Few data describe red cell osmotic fragility or deformability in patients with cholestasis who may or may not have spur cell anemia. Ektacytometry shows that red cell osmotic fragility and deformability are decreased in many children with cholestasis even when spur cell anemia has not yet occurred. Factors associated with decreased osmotic fragility include elevated serum bilirubin, elevated serum bile acids, and decreased serum vitamin E.

Severe anemia is associated with increased short-term and long-term mortality in patients hospitalized with cirrhosis

INTRODUCTION AND OBJECTIVES

The relationship between anemia and the outcome of patients with cirrhosis is not completely clear. Therefore, we performed this large-scale epidemiological study to investigate the prevalence and severity of anemia in patients with cirrhosis and acute decompensation or liver injury and how anemia impacts short-term and long-term outcomes.

PATIENTS AND METHODS

Patients with cirrhosis and acute decompensation (AD) or acute liver injury (ALI) were enrolled in the Chinese AcuTe on CHronic LIver FailurE (CATCH-LIFE) studies, which consisted of two large, multicenter, prospective, observational cohorts between January 2015 and December 2016 and July 2018 and January 2019. We conducted data analysis on the prevalence of anemia and determined the relationship between anemia and prognosis.

RESULTS

Among 1979 patients, 1389 (70.2%) had anemia, among whom 599 (41.3%) had mild anemia, 595 (15.8%) had moderate anemia and 195 (2.4%) had severe anemia. A linear association between hemoglobin level and 90-day or 1-year LT-free mortality was shown, and a 10 g/L decrease in hemoglobin level was associated with a 6.8% extra risk of 90-day death and a 5.7% extra risk of 1-year death. Severe anemia was an independent risk factor for 90-day [HR=1.649 (1.100, 2.473), p=0.016] and 1-year LT-free mortality [HR=1.610 (1.159, 2.238), p=0.005]. Multinomial logistic regression analysis further identified that severe anemia was significantly associated with post-28-day mortality but not within-28-day mortality.

CONCLUSIONS

Anemia is common in patients with cirrhosis admitted for acute events. Severe anemia was associated with poor 90-day and 1-year prognoses in these patients.

Spur cells in liver cirrhosis are predictive of acute-on-chronic liver failure and liver-related mortality regardless of severe anaemia

Chronic anaemia in advanced liver disease is a frequent finding. The aim was to explore the clinical impact of spur cell anaemia, a rare entity typically associated with end-stage of the disease. One-hundred and nineteen patients (73.9% males) with liver cirrhosis of any etiology were included. Patients with bone marrow diseases, nutrients deficiencies and hepatocellular carcinoma were excluded. In all patients, a blood sample was collected to check for the presence of spur cells on blood smear. A complete blood biochemical panel was recorded together with Child-Pugh (CP) score and Model for End-Stage Liver Disease (MELD) score. For each patients, clinically relevant events, such as acute-on-chronic liver failure (ACLF) and 1 year liver-related mortality, were registered. Patients were then grouped according to the percentage of spur cells at smear (> 5%, 1-5%, < 1%). Severe anaemia was defined as haemoglobin levels lower than 8 g/dL. 9.2% of subjects had > 5% spur cells, only 2 had evidence of haemolysis. In patients with > 5% spur cells, haemoglobin and albumin were lower compared with the other sub-group, while MELD score, CP score, International Normalized Ratio, ferritin, creatinine and unconjugated bilirubin were higher. Patients with more spur cells were more decompensated and developed more frequently ACLF. ACLF and liver-related mortality were significantly and independently associated with the presence of > 5% spur cells but not with baseline severe anaemia. Cirrhotic patients have a fairly high prevalence of spur cells, not always associated with severe haemolytic anaemia. The presence of spur red cells is per se associated with a worse prognosis and, therefore, should be always evaluated to prioritize patients for intensive management and eventually liver transplantation.

Spur Cell Anaemia in Cirrhosis: A Narrative Review

The presence of anaemia has been linked to increased complications and a worse prognosis in cirrhosis. Spur cell anaemia (SCA) is a specific form of haemolytic anaemia reported in patients with advanced cirrhosis. The literature on the entity has not been systematically reviewed, despite the classical association and frequent association with worse outcomes. We undertook a narrative review of available literature on SCA which yielded only 4 were original studies, one case series and the rest of the literature as case reports and clinical images. SCA is usually defined by the presence of spur cell rate of ≥5%, although there remains a lack of consensus in the definition. SCA has been classically associated with alcohol-related cirrhosis but can be seen across the spectrum of cirrhosis and acute to chronic liver failure. Patients with SCA tend to have evidence of higher grades of liver dysfunction, abnormal lipid profiles, worse prognostic scores and a high mortality. Experimental therapies including corticosteroids, pentoxifylline, flunarizine and plasmapheresis has been tried with variable effect, but liver transplantation remains the management of choice. We propose a stepwise approach to diagnosis and re-enforce the need for further prospective research, especially in subgroups of advanced cirrhosis like acute to chronic liver failure.

Binge drinking alongside alcoholic chronic abuse

Here is reported the case of an adult patient with ethylic cirrhosis associated with spur cell anemia. Moreover, acute vacuolation of leukocytes was observed in relationship with recent binge drinking.

A thorny matter: Spur cell anemia

Spur cell anemia (SCA) is an acquired form of non-autoimmune hemolytic anemia that occurs in advanced liver disease. It is characterized by the presence of acanthocytes or spur cells, spiculated erythrocytes whose shortened life span causes anemia that is unresponsive to transfusion. SCA has been regarded as a rare condition with an ominous prognosis for which the only known cure is liver transplantation, but recent prospective studies have demonstrated the existence of a milder form of SCA in which there are smaller numbers of acanthocytes, but which is nevertheless associated with hemolysis and poor outcomes. This form of SCA appears to be considerably more common than the severe classical variant. The conventional understanding of the pathogenesis of SCA is that abnormalities of lipid metabolism are the primary event driving the formation of spur cells. However, the studies that underpin this theory are based on small numbers of patients with heterogeneous clinical features and inconsistent use of nomenclature for dysmorphic red blood cells. In this review, we discuss the evolution of the current understanding of SCA and therapeutic strategies that have been employed based on this understanding. Our goal is to raise awareness of this understudied condition that has significant implications for patient outcomes. Furthermore, we highlight the need for rigorous, contemporary research into the underlying cause or causes of SCA in order to develop an effective therapy for this disorder.
