Presentation
In some cases, SRC was the initial presentation of scleroderma; there were no skin sclerosis during the time that SRC develops [ 8 ]. [omicsonline.org]
Three years before presentation, she had complained of sausage-like fingers, Raynaud's phenomenon, digital-tip ulcers and decreased wrinkles around her mouth. One year before presentation, she had dyspnea on effort. [jstage.jst.go.jp]
Clinical Pearls • How does systemic sclerosis typically present ? Systemic sclerosis or scleroderma has a female preponderance and typically presents in patients who are between 30 and 60 years of age. [blogs.nejm.org]
A patient with scleroderma renal disease and pulmonary hypertension who had a successful pregnancy with the use of angiotensin converting enzyme inhibitors is presented. [ncbi.nlm.nih.gov]
His serum creatinine gradually increased from 2.2mg/dl at presentation to 3.0 mg/dl at the time of discharge. [jpma.org.pk]

- Kidney Failure
Unless treated promptly, renal crisis leads to kidney failure, a condition in which the kidneys lose their ability to eliminate waste products from the body. [scleroderma.org]
When your kidneys lose their filtering ability, dangerous levels of fluid and waste accumulate in your body—a condition known as kidney (renal) failure. Mayo Clinic. Kidney Failure. When both of your kidneys fail, your body holds fluid. [sclero.org]
The abrupt onset of kidney failure and severe hypertension in patients with progressive systemic sclerosis. It is treated by controlling blood pressure with angiotensin converting enzyme inhibitors, sometimes in association with other agents. [medical-dictionary.thefreedictionary.com]
It may lead to complete kidney failure. It is not known what causes the crisis to develop. [edren.org]

Creatinine test As kidney function declines, your creatinine increases. This protein is also related to muscle mass. Parathyroid hormone (PTH) test The kidney and the parathyroid glands interact through the regulation of calcium and phosphorus. [healthline.com]
Treatment
For both, completely effective treatment is not available, mainly as a result of the lack of knowledge of its pathogenesis. [academy.theisn.org]
Because SRC most commonly stems from the progression of an existing diffuse disease state, the treatment of both is required, although these treatments are not inherently identical. Treatment Angiotensin-converting enzyme inhibitors (ACEIs). [consultant360.com]
Scleroderma renal crisis: poor outcome despite aggressive antihypertensive treatment. Intern Med J 2003; 33216-20. [jpma.org.pk]
What is the treatment? Treatments for scleroderma vary according to the problems you have. Various drugs (as well as warm gloves) may help Raynaud’s syndrome, for instance. [edren.org]
The advantage of photopheresis treatment is the low frequency of side effects related to treatment. The disadvantages are the practical efforts required and the high treatment cost [ 20, 21 ]. [clinmedjournals.org]
Prognosis
However, it can help to define prognosis and guide treatment in atypical forms. The prognosis of SRC has dramatically improved with the introduction of angiotensin-converting enzyme inhibitors (ACEi). [ncbi.nlm.nih.gov]
Nevertheless, the prognosis is still not good. Survival at one and five years is only 76% and 65%, respectively, for SRC patients treated with ACE inhibitors. [the-rheumatologist.org]
Prognosis is worse for males, but may not be related to corticosteroid use, presence of MAHA or severity of renal pathology. [academic.oup.com]

Etiology

CONCLUSION: Patients with diffuse scleroderma without renal crisis rarely have significant increases in serum creatinine or proteinuria that cannot be explained by other etiologies. [jrheum.org]
Prophylactic use of ACE inhibitors does not seem to decrease the risk of SRC (observed in other studies) so it may be the changing etiology of SSc over time. Disclosure: M. Turk, None; J. E. Pope, None. [acrabstracts.org]

It has been suggested that the RAAS may be less activated, leading to modest blood pressure (BP) elevation, 2 and that vascular insult and vasoconstriction are the culprits, rather than a renin-mediation etiology. [consultant360.com]

Pathology The pathophysiology is very similar to malignant nephrosclerosis and is characterized by pronounced constriction of arcuate and interlobular arterioles resulting in focal cortical ischemia. [radiopaedia.org]

Pathology Although the pathophysiology underlying SRC is not completely understood, it is accepted as being related to intimal thickening of the renal interlobular and arcuate arteries as a result of endothelial cell injury and abnormal oxidative stress [consultant360.com]
Prevention
Doctors recommend that you get the following vaccinations: pneumococcal vaccine hepatitis B vaccine influenza vaccine H1N1 (swine flu) vaccine You can’t always prevent CKD. [healthline.com]
Prevention No preventive measures have been validated in the literature to support predictable, reliable improvement in outcomes. [consultant360.com]
Interventions designed for Raynaud’s—protecting fingers and toes from trauma and cold temperatures, and staying warm—may prevent damage. [pharmacytimes.com]
To prevent death and serious organ damage TTP requires immediate treatment with plasma exchange (PLEX) – see Figure 5 for a diagram. [unckidneycenter.org]
There is limited evidence for treatments to prevent this damage or stop it progressing. Blocking a substance in the blood called endothelin has helped treat some aspects of scleroderma. [clinicaltrials.gov]
