Successful Spinal Cord Stimulation for Necrotizing Raynaud’s Phenomenon in COVID-19 Affected Patient: The Nightmare Comes Back

Spinal cord stimulation is currently used to treat a variety of chronic intractable painful conditions. We report a case of severe Raynaud’s phenomenon in the hands refractory to conservative treatment and responsive to diagnostic stellate ganglion block that was effectively treated with a spinal cord stimulator placed in the cervical epidural space. After capturing the affected areas with paresthesias, blood flow in the left hand and fingers significantly improved as evidenced by an increase in skin temperature, a change from cyanotic to pink appearance and concomitant reduction in pain. Moreover, the patient reported that limb ischemia and pain could be managed overnight with stimulation intensities that were below sensory perception thresholds. Thus it seems, at least in the overnight period, paresthesias were not required to maintain pain relief. This case presents a potential divergence between a requirement for paresthesias and pain relief in spinal cord stimulation therapy for the treatment of Raynaud’s phenomenon. The possible role of the sympathetic nervous system in this relationship is also discussed. Key words: spinal cord stimulator, Raynaud’s phenomenon, sensory perception

Flow Mediated Dilatation

Previous studies have shown that patients with Raynaud’s phenomenon secondary to systemic sclerosis present abnormal endothelial function; the mechanisms responsible for the endothelial dysfunction are unknown but increased vascular oxidative stress could be a possible cause. The hypothesis that a potent water-soluble antioxidant can reverse endothelial dysfunction in these patients was tested in the present study. We examined 11 female patients with Raynaud’s phenomenon secondary to systemic sclerosis and ten healthy control women by ultrasound imaging of the brachial artery to assess flow-mediated (endothelium-dependent) and nitrate-induced (endothelium-independent) vasodilatation. Flow-mediated dilatation and nitrate-induced dilatation were significantly reduced in patients with Raynaud’s phenomenon, indicating abnormal endothelial and smooth muscle cell function. Patients with Raynaud’s phenomenon entered a double-blind, randomized, crossover placebo-controlled trial and received orally 2 g of ascorbic acid or placebo; vascular studies were repeated two hours after ascorbic acid or placebo administration. Flow-mediated dilatation did not improve after ascorbic acid (1.6 ± 2.2% to 2.2 ± 2.5%, ns) or placebo administration (1.2 ± 1,9% to 1.7 ± 1.4%, ns); also nitrate-induced dilatation was similar after ascorbic acid or placebo (16 ± 7.4% vs 17 ± 8%, ns), suggesting no effect of ascorbic acid on endothelial and vascular smooth muscle function. In conclusion, ascorbic acid does not reverse endothelial vasomotor dysfunction in the brachial circulation of patients with Raynaud’s phenomenon secondary to systemic sclerosis. The use of different antioxidants or different dosing of ascorbic acid may be required to show a beneficial effect on endothelial vasodilator function.

Background: Prostanoids are used in the treatment of Raynaud’s phenomenon and acral perfusion disorders secondary to collagenosis. In subjective terms, intravenous administration of these agents produces success in more than 50% of patients. The therapeutic outcome of clinical administration of alprostadil or iloprost may vary from individual to individual. Patients and methods: The following variables were analysed in a cross-over study in 27 patients with collagenosis and Raynaud’s phenomenon: plasma viscosity and erythrocyte aggregation (rheological variables), partial pressure of oxygen and laser Doppler flowmetry in the finger region, and lymphocyte phenotyping and interleukin (IL) determinations (immunological variables). Results: Laser Doppler flowmetry revealed significant differences between patients with secondary Raynaud’s phenomenon and a control group of 25 healthy subjects. Laser Doppler readings did not change significantly as a result of the treatments. Therapy with iloprost produced a reduction in IL-1beta, L-selectin (CD 62 L) and IL-6. Conclusion: The change in immunological variables due to iloprost may explain the long-term effects of prostaglandins in the treatment of Raynaud’s phenomenon. From our results it is not possible to infer any preference for iloprost or alprostadil.

Digital Ischaemia

Abstract. The primary goal of therapy is to reduce the frequency and intensity of Raynaud’s attacks and to minimize the related morbidity rather than to cure the underlying condition. Treatment strategies depend on whether Raynaud’s phenomenon (RP) is primary or secondary. All patients should be instructed about general measures to maintain body warmth and to avoid triggers of RP attacks. Pharmacologic intervention can be useful for patients with severe and frequent RP episodes that impair the patient’s quality of life. Calcium channel blockers are currently the most prescribed and studied medications for this purpose. There has been limited evidence for the efficacy of alpha-1-adrenergic receptor antagonists, angiotensin receptor blockers, topical nitrates or fluoxetine to treat RP. The intravenously administered prostacyclin analogue iloprost can reduce the frequency and severity of RP attacks and is considered a second-line therapy in patients with markedly impaired quality of life, critical digital ischaemia and skin ulcers who are at risk for substantial tissue loss and amputation. Phosphodiesterase inhibitors (e.g., sildenafil) can also improve RP symptoms and ulcer healing whereas endothelin-1 receptor antagonists (e.g., bosentan) are mainly considered treatment options in secondary prevention for patients with digital skin ulcers related to systemic sclerosis. However, their use in clinical practice has been limited by their high cost. Antiplatelet therapy with low-dose aspirin is recommended for all patients who suffer from secondary RP due to ischaemia caused by structural vessel damage. Anticoagulant therapy can be considered during the acute phase of digital ischaemia in patients with suspected vascular occlusive disease attributed to the occurrence of new thromboses. In patients with critical digital ischaemia, consideration should be given to hospitalisation, optimisation of medical treatment in accordance with the underlying disease and evaluation for a secondary, possibly reversible process that is causing or aggravating the clinical symptoms.
