The real cause of intussusception is not fully understood and a variety of conditions have been associated with it (Meckel diverticulum, polyps, duplication cysts, parasites, Henoch-Schönlein purpura, cystic fibrosis, hemolytic-uremic syndrome and infectious gastroenteritis). Furthermore few European countries, following WHO recommendation to monitor baseline incidence of intussusception before implementation of immunization program for rotavirus, used intussusception rate as a baseline value to compare the same figures in the period before and after introduction of vaccination...

Helicobacter pylori (H. pylori) infection is a common worldwide infection that is an important cause of peptic ulcer disease and gastric cancer. H. pylori may also have a role in uninvestigated and functional dyspepsia, ulcer risk in patients taking low-dose aspirin or starting therapy with a non-steroidal anti-inflammatory medication, unexplained iron deficiency anemia, and idiopathic thrombocytopenic purpura. While choosing a treatment regimen for H. pylori, patients should be asked about previous antibiotic exposure and this information should be incorporated into the decision-making process...

An infant with presumed maternal immune thrombocytopenic purpura had persistent thrombocytopenia with platelet clumping. The patient had no significant bleeding symptoms in the first year of life and von Willebrand antigen and ristocetin cofactor activity were normal. Absent high molecular weight multimers ultimately led to a genetically proven diagnosis of type 2B von Willebrand disease (3964G>A VWF exon 28), highlighting the challenges of establishing this diagnosis in infants.

A 52-year-old man presented with a purpuric rash affecting his legs and hypertension. He was diagnosed with Henoch-Schönlein purpura and discharged with non-steroidal anti-inflammatory drugs. Three weeks later, he presented again with loss of appetite and vomiting before developing abdominal pain with pyrexia of 38.5°C and rigors. On examination, he was hypotensive with a distended abdomen and a national early warning score of 6. Computed tomography revealed enteropathy of Henoch-Schönlein purpura. The patient deteriorated and went for an emergency laparotomy, where 30cm of ischaemic small bowel was resected...

BACKGROUND: Capnocytophaga canimorsus is a Gram-negative bacterium, which belongs to the oral flora of dogs and causes fulminant sepsis in humans who have been bitten, licked or scratched. In patients, bleeding abnormalities, such as petechiae, purpura fulminans or disseminated intravascular coagulation (DIC) occur frequently. OBJECTIVE: We investigated whether C. canimorsus could actively contribute to these bleeding abnormalities. METHODS: Calibrated automated thrombogram and clotting time assays were performed to assess the anticoagulant activity of C...

Primary antibody deficiencies (PADs) are the most common inherited primary immunodeficiencies in humans, characterized by hypogammaglobulinemia, an inability to produce specific antibodies, and recurrent infections mainly caused by encapsulated bacteria. However, it has been shown that inflammatory disorders, granulomatous lesions, lymphoproliferative diseases, cancer, and autoimmunity are associated with the various types of PAD. Both systemic and organ-specific autoimmune diseases could be attributed to B-cell defects in PAD patients...

Idiopathic thrombocytopenic purpura (ITP) is an acquired thrombocytopenia without other clear cause of thrombocytopenia. It is not common in a singleton pregnancy and less common in twin pregnancy. We report a 33-year-old ITP pluripara whose first pregnancy was uneventful. She carried twin pregnancy, complicated by recurrent very low platelets, and gave birth to preterm twins. This patient received multiple courses of intravenous immunoglobulin (IVIG) and showed a significant platelet count improvement with IVIG therapy...

Among causes of childhood purpura, other- or self-induced mechanical purpura, such as factitious purpura, needs to be considered. This cause is unfamiliar to pediatricians, usually compromising early diagnosis. We report on the cases of six children, seen between 1998 and 2014 at the Toulouse and Bordeaux Departments of Dermatology, presenting with a stereotypical linear purpura on the arms. All were females, aged 6-14 years. One patient had a psychiatric history, whereas the others were undergoing a stressful time period...

Pulmonary involvement is extremely rare in thrombotic thrombocytopenic purpura. In this report, we present a girl patient with congenital thrombotic thrombocytopenic purpura, known as Upshaw-Schulman syndrome (USS), complicated with severe hemolysis and pulmonary hypertension (PH). The assay results of a disintegrin-like and metalloprotease with thrombospondin type 1 motifs 13 (ADAMTS13) activity measured by FRETS-VWF73 and ADAMTS13-act-ELISA were different. Hyperbilirubinemia (total bilirubin, 25.3 mg/dL) interfered strongly with the FRETS-VWF73 assay...

BACKGROUND: Ikaros, which is encoded by IKZF1, is a transcriptional factor that play a critical role in hematopoiesis. Somatic IKZF1 alterations are known to be involved in the pathogenesis of leukemia in human subjects. Recently, immunodeficiency caused by germline IKZF1 mutation has been described. OBJECTIVE: We sought to describe the clinical and immunologic phenotypes of Japanese patients with heterozygous IKZF1 mutations. METHODS: We performed whole-exome sequencing in patients from a dysgammaglobulinemia or autoimmune disease cohort and used a candidate gene approach in 4 patients...

Liver cirrhosis is the end stage of chronic liver disease, but no definitive pharmacological treatment is currently available. It has been reported that thrombopoietin (TPO) promotes liver regeneration and improves liver cirrhosis by increasing platelet count. We have shown the direct effect of platelet transfusion on the improvement of liver function in patients with chronic liver disease. However, platelet transfusion often causes adverse events, such as platelet transfusion refractoriness and pruritus. Therefore, we conducted an exploratory clinical trial and administered eltrombopag, an orally bioavailable, small-molecule, non-peptide TPO receptor agonist that has been approved for the treatment of chronic idiopathic thrombocytopenic purpura...

Glioblastoma is an aggressive brain tumor that requires multidisciplinary treatment including adjuvant radiotherapy, chemotherapy, and adjunct corticosteroids. Temozolomide is a commonly used chemotherapy drug and frequently causes lymphocytopenia. We describe the case of a 67-year-old woman with cutaneous invasive aspergillosis who had received long-term temozolomide and corticosteroid therapy for glioblastoma. She presented with multiple indurations, erythema, and purpura, some of which produced purulent discharge, in the anterior abdomen...

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS) are two important acute conditions to diagnose. Thrombotic Microangiopathy is a broad pathophysiological process that leads to microangiopathic hemolytic anemia, thrombocytopenia and involves capillary and small vessel platelet aggregates. The most common cause being disseminated intravascular coagulation (DIC), which may be differentiated by abnormal coagulation. Clinically, a number of conditions present with microangiopathic hemolytic anemia and thrombocytopenia (MAHAT), including cancer, infection, transplantation, drugs, autoimmune disease and pre-eclampsia and HELLP (Hemolysis, Elevated Liver enzymes, Low Platelet count) syndrome in pregnancy...

The acquired form of idiopathic thrombotic thrombocytopenic purpura (TTP) is an autoimmune disease, in which the underlying ADAMTS13-deficiency is caused by inhibitory autoantibodies against the protease. Human leukocyte antigens (HLA), responsible for antigen presentation, play an important role in the development of antibodies. The loci coding HLA DR and DQ molecules are inherited in linkage as haplotypes. The c.1858C>T polymorphism of the PTPN22 gene, which codes a protein tyrosine phosphatase important in lymphocyte activation, predisposes to a number of autoimmune diseases...

We report on the case of fatal "purpura fulminans" caused by Neisseria meningitidis W135 that occurred in a young French soldier vaccinated a few months earlier with the tetravalent conjugate vaccine ACYW135. Biological investigations revealed adequate titers of postvaccination antibodies against serogroups A, C, and W135 and led to the post-mortem diagnosis of a complete C7 complement deficiency. Late complement component deficiency is a well-known risk factor of meningococcal diseases, but usually exposes to recurrent mild infections, whereas severe invasive meningococcal diseases are more likely to occur among properdin-deficient patients...
