Presentation
Conclusion: Our patient had an unusual presentation of Hemolytic uremic syndrome characterized by severe thrombocytopenia and hemolytic anemia. [bloodjournal.org]
In this report, we describe a case of microangiopathic hemolytic anemia following myxoma excision and mitral valve repair, which was presented as hemolytic uremic syndrome. [synapse.koreamed.org]
Therefore, a high index of suspicion should be maintained on initial presentation. [clinicaladvisor.com]
Case report: The first patient presented with pneumococcal pneumonia and empyema and the second patient presented with pneumococcal pneumonia and meningitis. [latunisiemedicale.com]
Presents a multi-disciplinary and international approach to critical renal care for a thorough and integrated presentation of how to care for critically ill patients with renal disease or complications. [books.google.ro]
Entire Body System
- Anemia
It seems that an upper respiratory infection caused both autoimmune hemolytic anemia (AIHA) and aHUS in our patient. [caspianjp.ir]
This article looks at the role of uremic toxicity in exacerbating the anemia of chronic renal failure. [ncbi.nlm.nih.gov]
Thrombocytopenia, kidney failure and anemia are the major signs [ 1, 2, 3 ]. The hemolytic anemia is type as evidenced by the collapse of haptoglobin and elevation of LDH [ 4 ]. [em-consulte.com]

Hemolytic anemia also occurs as a rare complication after mitral valve repair. [synapse.koreamed.org]
- Pallor
Excoriations (uremic pruritus), pallor (anemia), muscle wasting, and a nitrogenous fetor are all signs of advanced CKD, as are pericarditis, pleuritis, and asterixis, complications of particular concern that usually prompt the initiation of dialysis. [accessmedicine.mhmedical.com]
[…] factors use of antimotility agents in EHEC diarrhea use of antibiotics in EHEC diarrhea Presentation Symptoms prodromal gastrointestinal illness abdominal pain bloody diarrhea nausea vomiting fatigue (anemia) oliguria/anuria (renal failure) Physical exam pallor [medbullets.com]
Following the prodrome, there is a sudden onset of pallor, irritability, weakness and lethargy. Petechaie and purpura are uncommon features of HUS and severe bleeding is extremely rare (1). [hawaii.edu]
Symptoms Signs and symptoms of HUS can include: Bloody diarrhea Decreased urination or blood in the urine Abdominal pain, vomiting and occasionally fever Pallor Small, unexplained bruises or bleeding from the nose and mouth Fatigue and irritability Confusion [mayoclinic.org]
CLINICAL FEATURES The commonest clinical presentation of HUS is : Acute pallor Oliguria Diarrhea or dysentery It occurs commonly in children between 1-5 years of age HUS develops about 5-10 days after onset of diarrhea 14. [slideshare.net]
Cardiovascular
- Tachycardia
His heart has a regular rhythm with tachycardia and a grade II/VI vibratory systolic ejection murmur at the left sternal border without radiation. No heaves, lifts, thrills, rubs, or gallops are present. His lungs are clear with good aeration. [hawaii.edu]
Workup
The family history is paramount in the workup of autosomal dominant polycystic kidney disease or hereditary nephritis (Alport’s syndrome). [accessmedicine.mhmedical.com]
Diagnostic Workup for Hemolytic-Uremic Syndrome Laboratory investigations are helpful in the evaluation of the HUS patient. Urine analysis confirms acute renal injury as proteinuria and hematuria are common. [lecturio.com]
After failing to respond to plasmapharesis and with normal ADAMTS13 levels, she was started on eculizumab therapy while more workup was performed. [pubs.sciepub.com]
[…] and lead to an increase in the levels of free radicals, thus introducing cell damage, increased platelet aggregation, increased binding of tissue plasminogen activator in the endothelium, and increased expression of local procoagulant factors. 47 Lab workup [scielo.br]
Serum
- Normocytic Normochromic Anemia
[…] of chronic kidney disease : ↓ hemoglobin, ↔︎ MCV Pathophysiology: ↓ erythropoietin → decreased stimulation of RBC production → normocytic, normochromic anemia Urinalysis : : possibly abnormal urine sediment ( see nephritic sediment, nephrotic sediment [amboss.com]
A blood smear exam showed mild normocytic normochromic anemia with anisocytosis and polychromasia. [synapse.koreamed.org]
Biochemistry revealed: normocytic normochromic anemia (Hb 6 g/dL); platelet count 132 × 10 9 L −1, acute kidney injury (Urea 81 mmol/L; Creatinine 1487 μmol/L); high Lactate dehydrogenase (LDH 23 μkat/L) and proteinuria (100 mg/dL). [medintensiva.org]
Treatment
Each cycle consisted of three weekly treatments (j1 to j8, j15 1000 mg/m 2 ) followed by a week of rest. [em-consulte.com]
Another cause of treatment failure is presence of occult infection. [sjkdt.org]
an increase in serum creatinine by 25% or more compared to baseline or nadir during Soliris treatment; or, an increase in serum LDH by 25% or more over baseline or nadir during Soliris treatment. [soliris.net]

We aimed to investigate the effects of intravenous iron treatment followed by subcutaneous α-darbepoetin treatment on erythrocyte redox status in nine nondialysis patients with CKD ( Table 1 ). [jasn.asnjournals.org]
Prognosis
Conclusions: Since the atypical hemolytic–uremic syndrome has a poor prognosis, its death rates is as high as 25% and it progresses to end-stage renal disease in half of the patients. [caspianjp.ir]
The long-term prognosis is related to the underlying malignancy [ 1 ]. Our patient’s course of the syndrome was a favorable change after chemotherapy and blood transfusion. [em-consulte.com]
The prognosis is poor, recurrences are frequent, and the mortality rate is 60-70%. Autosomal dominant HUS often occurs in adults, who have a poor prognosis. The risk of death or ESRD is 50-90%. [emedicine.medscape.com]
No No No Treatment Supportive care with fluids to maintain renal perfusion dialysis if acute renal failure unresponsive to fluids Fresh frozen plasma can be used (increases coagulation factor levels) Plasmapheresis or plasma exchange for severe cases Prognosis [medbullets.com]
Etiology
Use Additional Use Additional Help Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10data.com]
In general, kidneys that have shrunk ( Once chronicity has been established, clues from the physical examination, laboratory panel, and urine sediment evaluation can be used to determine etiology. [accessmedicine.mhmedical.com]
Till date, a total of 22 cases have been described to develop HUS/TTP following pancreatitis of varied etiology. [ijccm.org]
Based on the absence of a previous infectious condition and any signs of rejection in the endocardial biopsy that could be triggers, and given the recent introduction of sirolimus, the latter was considered the etiological factor, with blood levels within [revespcardiol.org]
So, we still view many of these diseases of unknown etiology as multi-factorial, "complex" diseases. [scienceblogs.com]
Epidemiology

First, the stx loss in an EHEC strain during infection can mislead epidemiological investigations because an stx -negative strain would not be, based on currently used criteria, considered to be epidemiologically related to stx -positive strains, even [journals.plos.org]
Epidemiology HUS has been characterized as either epidemic/endemic (or prodromal) or sporadic (nonprodromal). [pedsinreview.aappublications.org]

Pathophysiology
This has led to greater understanding of the pathophysiological factors regulating hematopoiesis. This in turn, hasprompted the search for new therapeutic approaches. [ncbi.nlm.nih.gov]
Endothelial cell dysfunction, probably because of the effects of complement activation, is an intermediate stage in the pathophysiologic cascade. Atypical HUS has a grave prognosis. [journals.lww.com]

Prevention

Moreover, EPO and its receptors have been found in the brain, suggesting a role in preventing neuronal death. [ncbi.nlm.nih.gov]

How can HUS be prevented? Preventing infection by bacteria, especially E. coli O157:H7, is key to preventing HUS. The following measures can help prevent infection with E. coli O157:H7: Never eat rare or undercooked ground beef. [vdh.virginia.gov]
