A middle-aged woman had five discrete episodes of herpes zoster. The first attack consisted of uncomplicated herpes zoster ophthalmicus. The subsequent four episodes involved thoracic, cervical, and finally sacral dermatomes and were complicated by myelitis or encephalomyelitis. During the most recent attack, while she was receiving corticosteroids, varicella-zoster virus was cultured from the CSF. In addition, the patient had strong evidence of systemic lupus erythematosus, with a history of Raynaud's phenomenon, migratory arthralgia, and unexplained anemia before the first attack of zoster with subsequent development of a positive lupus cell preparation and elevated antinuclear antibody levels.

Phophodiesterases inhibitors (PDEis) act by inhibiting the catabolism of cyclic nucleotides, cAMP and cGMP, which are ubiquitously expressed in cells of the immune system. Increased levels of cAMP and/or cGMP have been reported to decrease the activity of pro-inflammatory TH1 cells, attenuate experimental autoimmune encephalomyelitis and experimental arthritis. PDE5i like Sildenafil improves endothelial dysfunction and vascular remodelling in patients with pulmonary artery hypertension and refractory secondary Raynaud's phenomenon, with a potential to cause disease modification in the former. Studies in animal models of fibrosis suggest that these drugs have anti-fibrotic effect and may be potentially useful in conditions like scleroderma. They also have been shown to have renoprotective effect in animal models. The emerging trends make it necessary to exploit the full therapeutic potential of this class of drugs in various autoimmune diseases like rheumatoid arthritis, scleroderma, profibrotic conditions and PAH.
