- Inflammation
In this setting, host cells become targets for repeated complement attacks, causing inflammation and cellular damage. Thus, blockage of C5 by eculizumab should be protective for host cells in aHUS. [cjasn.asnjournals.org]
About Omeros Corporation Omeros is a commercial-stage biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, complement-mediated [markets.businessinsider.com]
By inhibiting the complement cascade at this point, the normal, disease-preventing functions of proximal complement system are largely preserved, while the properties of C5 that promote inflammation and cell destruction are impeded. [17] Eculizumab inhibits [en.wikipedia.org]

Donor-specific antibodies activate the complement in the endothelium which triggers acute rejection and facilitates the inflammation process of chronic rejection. [revistanefrologia.com]
- Fatigue
During eculizumab treatment (dosed 600 mg iv every 7 days, weeks 1-4 and 900 mg biweekly starting in week 5) he felt better, seemed less fatigued and experienced less erectile dysfunction. [ash.confex.com]
compared to placebo. 11 Similarly, improvements were demonstrated in several QoL parameters including physical, emotional, and cognitive functioning, global health, fatigue, dyspnea, and insomnia. 12 Similarly, the AEGIS study also showed a consistent [dovepress.com]
Upon admission at age 25, she presented with complaints of abdominal pain, fatigue, and diarrhea. [austinpublishinggroup.com]
By using the Functional Assessment of Chronic Illness Therapy Fatigue instrument (scores can range from 0 to 52, with higher scores indicating improvement in fatigue), the trial showed a reduction in fatigue (MD 10.4, 95% CI 9.97 to 10.83; P = 0.00001 [aetna.com]
They present with clinical features of unexplained hemolytic anemia like fatigue, jaundice and red colored urine. [ijcasereportsandimages.com]
- Pallor
On examination she was afebrile, pulse rate 80/min, blood pressure 110/70 mmHg, marked pallor was present. Cardiovascular and respiratory examination were normal. Her abdomen was soft with minimal distension and diffuse tenderness. [ijcasereportsandimages.com]
Apart from mild pallor, the remainder of the physical examination was unremarkable. The family history was notable for thrombotic microangiopathy in a first cousin who died at age 36 after receiving 3 kidney transplants. [benthamopen.com]

Neurologic
- Hyperactivity
Systemic Lupus Erythematosus Robak and Robak (2009) stated that systemic lupus erythematosus (SLE) is an autoimmune disease characterized by B cell hyperactivity and defective T-cell function, with production of high titer auto-antibodies. [aetna.com]
Urogenital
- Kidney Failure
Given the lack of response to therapy and the occurrence of kidney failure requiring dialysis, we used eculizumab as rescue therapy, a monoclonal humanized antibody against the complement component C5. [pediatrics.aappublications.org]
This can lead to low red blood cell counts (anaemia), tiredness, difficulty in functioning, pain, dark urine, kidney failure, shortness of breath and blood clots. [news-medical.net]

The majority of children with D(+) HUS develop some degree of renal insufficiency, and about 2/3 of children with HUS will require dialysis, while about 1/3 will have milder renal involvement without the need for dialysis. [aetna.com]
- Renal Injury
Oosterveld et al. (2015) also consider that ongoing production of C3 degradation products may lead to chronic inflammatory changes and, in the long run, renal injury. [nice.org.uk]
- Renal Function Impairment
All patients, regardless of the presence of concomitant LN, presented with severe hypocomplementemia and renal function impairment. [aetna.com]
Workup
Workup for connective tissue diseases like ANA, dS-DNA and APLA were done and found to be negative. Bone marrow biopsy was done and revealed hypercellular marrow with no other abnormality. [ijcasereportsandimages.com]
Systematic workup also ruled out HIV infection, antiphospholipid syndrome, and occult infection. Ultrasound showed kidneys of normal size, without thrombosis of renal arteries but with global bilateral hypoperfusion. [journals.lww.com]
The authors concluded that given the complexity of disease pathogenesis in C3G, a patient-tailored approach including a comprehensive workup of complement abnormalities is necessary to evaluate the best treatment options. [aetna.com]
Treatment
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]
Better data on the treatment of acute manifestations of the disease and long term treatment would be required. [pbs.gov.au]
After eculizumab treatment, 80% of plasma-resistant patients required no dialysis treatment. [sjkdt.org]
In 1 patient, sC5b‑9 was elevated and became normal with treatment. However, it was normal before (and throughout) treatment in the other patient. [nice.org.uk]
Soliris typically costs around £340,000 for the first year of treatment of aHUS and £327,000 per year thereafter. According to the Summary of Product Characteristics, treatment is for life. [blog.gfk.com]
Prognosis
Annual incidence of aHUS in adults and under the age of 18 are 2/1,000,000 and 3.3/1,000,000, respectively. [4], [5] Frequent relapses are seen in aHUS, and its prognosis is much worse than typical HUS. [6], [7] In 50% of children and in the majority [sjkdt.org]
Prognosis is poor. Most patients are identified during childhood, and many do not live to adulthood. Currently, there are an estimated 140 to 200 aHUS patients in the UK. [blog.gfk.com]
Conversely patients with mutations in the CFH, CFI, CFB and C3 genes have a much poorer prognosis and for patients with CFH and CFI mutations, a very high chance of recurrence of disease following kidney transplant. [pbs.gov.au]
On admission, a high plasma creatinine level indicated a poor prognosis, and hemodialysis had to be started. [cjasn.asnjournals.org]
Proof of this is that it TMA worsens the prognosis and survival of the patient in all situations in which it complicates the underlying disease: post-partum, kidney transplant and HSCT, MHTN, autoimmune diseases and glomerulopathies. [revistanefrologia.com]
Etiology
Hetero MTHFR C677T, hetero FVL, and hetero MTHFR A1298C were the most common etiological factors being responsible for 57.1, 42.9, and 42.9% of primary BCS cases, respectively. [worldwidescience.org]
These investigators stated that it would be worthwhile to examine if all cases of immune complex-mediated MPGN without clear underlying etiology should undergo work-up for abnormalities in the alternate complement pathway. [aetna.com]

Pathophysiology
The development of heart failure under complement inhibition and the absence of overt myocardial vascular lesions at postmortem examination suggested an independent pathophysiological process, possibly related to abnormal vasoreactivity. [4] In conclusion [journals.lww.com]
A recent contribution strongly underlined the possibility of recognizing a new mechanism of TA-TMA pathophysiology where the kidney seems the most common organ affected by small vessels injury [ 17 ]. [omicsonline.org]

However, the abrogation of intravascular hemolysis is not the only relevant change in PNH pathophysiology associated with eculizumab treatment. [jhoonline.biomedcentral.com]
Prevention
This mutation prevented binding andblockade by eculizumab, thereby explaining the poorresponse to the drug. However, the functional capacityof the mutant C5 to cause haemolysis was retained. [documents.tips]
This prevents breakdown of red blood cells that occurs in the circulation and turns very dark urine clear almost overnight—in almost all patients. [aamds.org]
The increased risk of meningococcal infection seems to be due to the critical action of the terminal complement in prevention of such infections. [austinpublishinggroup.com]
Thrombosis Prevention and Management The effect of withdrawal of anticoagulant therapy during Soliris treatment has not been established. Therefore, treatment with Soliris should not alter anticoagulant management. [soliris.net]
