BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD) deficiency anemia is associated with intravascular hemolysis. The freely filtered hemoglobin can damage the kidney. We aimed to assess any subclinical renal injury in G6PD children. METHODS: Sixty children were included. Thirty G6PD deficiency anemia children were enrolled during the acute hemolytic crisis and after the hemolytic episode had elapsed. Another thirty healthy children were included as controls. Serum cystatin C, creatinine levels, and urinary albumin/creatinine (A/C) ratio were measured, and the glomerular filtration rate (GFR) was calculated...

INTRODUCTION: Patients with sickle cell anemia (SCA) may present chronic hemolytic anemia, vaso-occlusion and respiratory tract infection (RTI) episodes. Galectin-3 (GAL-3) is a multifunctional protein involved in inflammation, apoptosis, adhesion and resistance to reactive oxygen species. Studies point to a dual role for GAL-3 as both a circulation damage-associated molecular pattern and a cell membrane associated pattern recognition receptor. OBJECTIVE: To investigate associations between the SNPs of GAL-3 gene (LGALS3) and serum levels with RTI and vaso-occlusive crisis (VOC) in children with SCA...

Pain, the hallmark complication of sickle cell disease (SCD), is largely managed with opioid analgesics in the United States, but comprehensive data regarding the long-term use of opioids in this patient population is lacking. The pain medication prescription records from a cohort of 203 SCD patients were analyzed. Twenty-five percent were not prescribed opioid medications while 47% took only short-acting opioids, 1% took only long-acting opioids, and 27% took a combination of short-acting and long-acting opioids...

Management of patients with metastatic squamous cell skin cancer, refractory to initial therapy with standard chemotherapy and radiation protocols, remains difficult with poor overall prognosis and limited therapeutic options. Recently, promising response rates with nivolumab, a programmed death receptor-1-blocking antibody, in squamous cancer of the head and neck have been demonstrated. Considering the similar histological patterns of squamous cell cancer of the skin and squamous cell cancer of the head and neck, we assumed that nivolumab could also be effective in our patients with refractory metastatic squamous cell cancer of the skin...

Delayed hemolytic transfusion reaction (DHTR) is one of the most feared complications of sickle-cell disease (SCD). We retrospectively analyzed the clinical and biological features, treatments and outcomes of 99 DHTRs occurring in 69 referral center patients over 12 years. The first clinical signs appeared a median of 9.4 [IQR, 3-22] days after the triggering transfusion (TT). The most frequent DHTR-related clinical manifestation was dark urine/hemoglobinuria (94%). Most patients (89%) had a painful vaso-occlusive crisis and 50% developed a secondary acute chest syndrome (ACS)...

We report the case of a 2 year-old boy hospitalized into the emergency room for influenza pneumonia infection. The evolution was marked by a respiratory distress syndrome, a severe hemolytic anemia, associated with thrombocytopenia and kidney failure. First, a diagnosis of hemolytic uremic syndrome (HUS) has been judiciously suggested due to the classical triad: kidney failure, hemolytic anemia and thrombocytopenia. But, strikingly, blood smears do not exhibit schizocytes, but instead ghosts and hemighosts, some characteristic features of a glucose-6-phosphate dehydrogenase deficiency...

Sickle cell disease (SCD), one of the most common genetic disorders worldwide, is characterized by hemolytic anemia and tissue damage from the rigid red blood cells. Although hydroxyurea and transfusion therapy are administered to treat the accompanying tissue injury, whether either one prolongs the lifespan of patients with SCD is unknown. SCD-related mortality data are available, but there are few studies on mortality-related factors based on evaluations of surviving patients. In addition, ethnic variability in patient registries has complicated detailed analyses...

In patients with sickle cell disease, thrombotic microangiopathy is a rare complication. Also in sickle cell disease, intracardiac thrombus formation without structural heart diseases or atrial arrhythmias is a rare phenomenon. We herein describe a 22-year-old woman, who was a known case of sickle cell-βthalassemia, had a history of recent missed abortion, and was admitted with a vaso-occlusive crisis. The patient had manifestations of microangiopathic hemolytic anemia, including laboratory evidence of hemolytic anemia, thrombocytopenia, respiratory distress, fever, jaundice, and abnormal liver function and coagulation tests, accompanied by clot formation on the Eustachian valve of the inferior vena cava in the right atrium and also a long and worm-like thrombus in the right ventricle...

Asymptomatic malaria (ASM) has been implicated in the development of hemolytic crisis in infected sickle cell anemia (SCA) patients worldwide. This study surveyed steady state SCA Nigerian patients for ASM to investigate the influence of malaria prevention behaviors and age on parasitaemia and multiplicity of infection (MOI). A total of 78 steady SCA patients aged 5 - 27 years on routine care at three health facilities in Lagos were investigated for ASM by light microscopy and PCR with a multiplicity of infection determined by genotyping block 2 of merozoite surface protein 1 (msp1) gene of Plasmodium falciparum (P...

A 46-year-old female with interstitial lung disease presented with proximal muscle weakness, worsening hypertension, microangiopathic hemolysis, thrombocytopenia and deteriorating renal function. She had no sclerodactyly, but had abnormal capillaroscopy. She tested positive for PM-Scl antibodies, and a renal biopsy showed an acute thrombotic microangiopathy consistent with scleroderma renal crisis (SRC). She failed to respond to corticosteroids, plasmapheresis and renin-angiotensin pathway inhibitors. She recovered quickly with the anti-C5 antibody, eculizumab...

BACKGROUND AND AIM: Cold agglutinin syndrome (CAS) primary or secondary represents approximately 16-32% of autoimmune hemolytic anemia cases. Most patients present with mild, chronic hemolytic anemia with exacerbation of the condition in the cold environment. Red cell transfusions are only indicated when there is a life-threatening anemia causing crisis. We studied the clinical and serological characterization of CAS with the aim that the information gained from this study would help in proper diagnosis and management of these patients...

Human parvovirus (HPV) B19 induced aplastic crisis in a family leading to the diagnosis of hereditary spherocytosis (HS) is a very rare condition being barely reported in the literature. We herein report a 4-year-old girl, her brother, and their mother who all presented with progressive pallor and jaundice after a febrile illness. The HPV B19 was diagnosed using polymerase chain reaction (PCR) and positive serology for specific anti-HPV B19 IgM. They were further diagnosed with having HS. The clinical importance of this report is that in the case of an abrupt onset of unexplained severe anemia and jaundice, one should consider underlying hemolytic anemias mostly hereditary spherocytosis complicated by HPV B19 aplastic crisis...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hemolytic anemia, which generally affects women of childbearing age. PNH hemolysis increases the risk of complications such as thrombosis during pregnancy and the postpartum period. Management of a pregnant woman with PNH remains a challenge due to the high incidence of thrombotic complications and the difficulty of differentiating a PNH crisis from the complications of pregnancy. PNH is associated with an increased rate of premature labor and fetal loss. Eculizumab, a C5 complement inhibitor, is a potential therapeutic option for such patients...

In the past 10 years, we have diagnosed congenital hemolytic anemia in 294 patients, approximately 33% of whom were found to have glucose-6-phosphate dehydrogenase (G6PD) deficiency. It is becoming more common for Japanese to marry people of other ethnic origins, such that G6PD deficiency is becoming more prevalent in Japan. Japanese G6PD deficiency tends to be diagnosed in the neonatal period due to severe jaundice, while G6PD-deficient patients with foreign ancestors tend to be diagnosed at the onset of an acute hemolytic crisis before the age of six...

In a patient with sickle cell disease receiving chronic transfusion, exacerbation of anemia with reticulocytopenia must prompt consideration of a delayed hemolytic transfusion reaction with hyperhemolysis, as further transfusion may worsen this condition; definitive diagnosis is sometimes difficult. Anemia evolving during parvovirus B19-induced erythroid hypoplasia (transient aplastic crisis) should be attenuated in chronic transfusion patients due to superior survival of transfused over endogenous red blood cells...

BACKGROUND: Patients who present with unexplained thrombocytopenia, that is, hemolytic anemia with end-organ dysfunction with a normal coagulation profile are suspected to have thrombotic thrombocytopenic purpura (TTP) and are usually referred to a plasma exchange (PE) center for immediate treatment to prevent mortality. Here, we describe the distribution and outcomes of patients with suspected TTP referred to a single center for PE therapy. METHODS: In this retrospective cohort study, we reviewed the data of all consecutive patients who were treated with PE for suspected TTP at our center between January 2000 and December 2011 (Canada)...

BACKGROUND: Medical therapy is rarely effective in patients with fulminant Wilson's disease (FWD). Liver transplantation is limited by the lack of donor liver in most patients with FWD at the time of diagnosis. New Wilson's index, model for end-stage liver disease (MELD) and Child-Pugh score are useful tools for decision-making of liver transplantation; however, none of them is an independent decisive tool. It is worthwhile to explore a more effective and practical therapeutic strategy and reevaluate the prediction systems for patients with FWD...

SCLERODERMA: renal crisis (SRC), a somewhat rare but serious complication of systemic scleroderma, is one of only a few known rheumatologic emergencies; it presents in as many as 10% of patients with scleroderma. Before the use of angiotensin converting enzyme (ACE) inhibitors to treat SRC, the mortality rate for SRC was extremely high-as much as 90% after 1 year. However, the mortality rate has significantly improved with the early and aggressive use of ACE inhibitors. SRC typically includes acute renal failure and accelerated hypertension...
