Raynaud's phenomenon is characterized by transient reduction in blood supply through the small arteries in the hands and feet. Severe Raynaud's phenomenon can cause digital necrosis. It has been hypothesized that nitric oxide may have a role in Raynaud's phenomenon. We report two cases in which oral L-arginine reversed digital necrosis in Raynaud's phenomenon and two additional cases in which the symptoms of severe Raynaud's phenomenon were improved with oral L-arginine. These reports suggest… 

Raynaud's phenomenon: Current concepts.

New lines in therapy of Raynaud’s phenomenon

TLDR
Main groups of medications as well as non-pharmacological regimen, that are used for the treatment of RP are presented to highlight the necessity of immediate assessment and treatment in severe forms of the disease with digital ulcers.

The clinical effects of l‐arginine and asymmetric dimethylarginine: implications for treatment in secondary Raynaud's phenomenon

TLDR
While there is no established dosing regimen, studies of oral l_arginine in secondary RP suggest that divided dosing may begin at 1_2 g/day and may be titrated up to 10 g/ day.

Raynaud phenomenon and the vascular disease in scleroderma

TLDR
Continued progress in the investigation of the vascular aspects of scleroderma is described in this review, with immune involvement in the early stages of the disease and mechanism of vascular repair in advance cases being some of the highlights of last year’s progress.

Raynaud's Phenomenon: Etiology and Management

L-Arginine in pregnant scleroderma patients

TLDR
It is suggested that L-arginine may be a useful therapeutic agent in pregnant SSc women because of its role in the prevention and treatment of preeclampsia.

Complementary therapies for patients with systemic sclerosis

TLDR
This review summarizes current data regarding various complementary therapies in systemic sclerosis and concludes with recommendations.

Improvement in digital flexibility and dexterity following ingestion of sildenafil citrate (viagra) in limited systemic sclerosis.

TLDR
A 66-year old man with a 20-year history of limited systemic sclerosis and discoid lupus erythematosus– induced scarring alopecia presented to the authors' clinic for follow-up and was found to have sclerodactyly affecting all the digits of his hand, giving rise to the ”prayer sign” when the palms of his hands were opposed with maximum extension of the small joints of the hands.

TLDR
The initial presence of autoantibodies increases the chance by 63-fold of developing connective tissue diseases, and such immunologic testing can be usefully combined with nailfold vessel microscopy, and several factors are considered to be of etiologic importance in Raynaud's phenomenon.

Skin blood flow in patients with systemic sclerosis and Raynaud's phenomenon: effects of oral L-arginine supplementation.

TLDR
There is an abnormality of endothelial dependent vasodilatation in the digital vasculature of patients with SSc and the lack of effect of supplementation with L-arginine suggests the abnormality may be independent of the L- arginine/nitric oxide pathway and may involve prostanoids.

Response of digital arteries to endothelium dependent and independent vasodilators in patients with Raynaud's phenomenon

TLDR
A dysfunction of endothelium‐dependent vasodilation is present in RP patients, and a sequential series of infusions alternating with physiological saline suggested that this dysfunction might contribute to the development of this spasm.

Nitroglycerin relaxes rat tail artery primarily by lowering Ca2+ sensitivity and partially by repolarization.

TLDR
Investigation of physiological relevance of guanosine 3',5'-cyclic monophosphate (cGMP)-induced relaxation of arterial smooth muscle suggests that nitroglycerin relaxes precontracted rat tail artery primarily by decreasing the [Ca2+]i sensitivity of force.

cGMP‐mediated phosphorylation of heat shock protein 20 may cause smooth muscle relaxation without myosin light chain dephosphorylation in swine carotid artery

TLDR
The findings suggest that regulatory systems, other than MLC phosphorylation and Ca2+, partially mediate nitroglycerine‐induced relaxation and that cGMP‐mediated phosphorylated HSP20 on Ser16 may have a role in smooth muscle relaxation without MLC dephosphorylation.

Oral L-arginine supplementation and cutaneous vascular responses in patients with primary Raynaud's phenomenon.

TLDR
Cutaneous vascular responses in the fingers were assessed during iontophoresis of acetylcholine and sodium nitroprusside, which are endothelium-dependent and endothelia-independent vasodilators.
