Patients with nail psoriasis can develop a wide variety of nail ch. It has been estimated that 80 to 90 percent of patients with psoriatic arthritis develop nail involvement 6,7. CLINICAL MANIFESTATIONS Patients with nail psoriasis may present with involvement of a single nail, multiple nails, both fingernails and toenails, fingernails only, or toenails only 17. Although topical therapy is widely used, studies on efficacy are limited. However, a substantial number of patients may lose efficacy, have adverse effects or find intravenous or subcutaneous administration inconvenient. In a cohort study of 1,593 patients with psoriasis, nail dystrophy was a significant predictor of co-existing PsA (hazard ratio 2. Modest improvements in psoriasis have been reported in randomized, double-blind, controlled studies of sulfasalazine 138, 140. Direct comparison studies have not yet been conducted for many of the biologic therapies, which may make it difficult to determine whether one agent is more beneficial in treating specific patient symptoms. Several therapies with modest efficacy have been studied in nail psoriasis. Among available agents, higher quality data are available to support the efficacy of cyclosporine and infliximab.
There are many therapeutic approaches for psoriasis in difficult to treat locations. Only a few of the therapies have been evaluated for efficacy and safety in well-designed and well-con-trolled clinical studies. In clinical studies, tacalcitol formulations (cream, ointment or emulsion) have shown. There is good evidence that many of the biologic treatments initially tested in psoriasis are also effective in PsA. Similar efficacy has also been demonstrated in psoriatic nail treatment 36, 37. An exploratory open-label study found modest clinical improvement in ACR20 and enthesitis scores, but no improvement of PASI scores, dactylitis or BASDAI scores 94. The older Moll and Wright criteria to classify PsA have been largely supplanted by the Classification of Psoriatic Arthritis (CASPAR) classification criteria, which have been shown to have high sensitivity and specificity in diverse settings 4. Central to any assessment of the efficacy of therapies are the outcome measures used to quantify disease activity across various domains of disease, both in clinical studies and in the clinic. Interestingly, in RA, IL-17 inhibitors have also been studied, and clinical responses appeared to be modest compared with therapies with other mechanisms of action. PsA is a chronic inflammatory condition with significant heterogeneity in clinical manifestations, including skin and nail psoriasis, enthesitis, dactylitis, axial arthritis and peripheral arthritis.
Only systemic therapies are likely to help nail psoriasis. Current treatments are either modestly effective or have substantial risk. 21Snellman, E. Comparison of the antipsoriatic efficacy of heliotherapy and ultraviolet B: a cross over study. Only systemic therapies are likely to help nail psoriasis. The pathogenesis of psoriasis has been obscure until only recently. Recently, several lines of evidence have suggested involvement of the immune system. They have modest efficacy(19). Double-blind, placebo-controlled study has been done to evaluate the clinical efficacy and tolerability of topical Aloe vera extract 0. In all forms of acquired baldness, skin that has previously been protected may be subjected to strong sunlight. For many men, there is no effective affordable treatment; therefore, acceptance is the management strategy. Alopecia areata is a chronic inflammatory disease, which affects hair follicles and sometimes nails.

Additionally, the anti-TNF antibodies adalimumab and infliximab have the capability of lysing cells involved in the inflammatory process, whereas the receptor fusion protein apparently lacks this capability. Several therapies with modest efficacy have been studied in nail psoriasis. Among available agents, higher quality data are available to support the efficacy of cyclosporine and infliximab, a TNF antagonist. Ustekinumab has been shown in small studies to be useful in other forms of psoriasis, including nail psoriasis, erythrodermic psoriasis and palmoplantar pustulosis. Following multiple subcutaneous doses of ustekinumab, the steady-state serum concentrations were achieved by week 28. Ustekinumab was shown to result in modest clinical improvement in a phase II study in patients with psoriatic arthritis. Perhaps the most comprehensive field study was performed in the Faroe Islands, where 2. However, this pathway is probably not the exclusive means of neutrophil recruitment, since an interleukin-8 blocking monoclonal antibody had only modest efficacy in a clinical study.74. Most accepted treatments for psoriasis have been developed empirically or were found by chance. In 5 studies, we found significant improvement of nail psoriasis compared to placebo: with infliximab (5 mg/kg), golimumab (50 mg and 100 mg), superficial radiotherapy, electron beam, and grenz rays. Although powerful systemic treatments have been shown to be beneficial, they may have serious adverse effects. Trials should accurately describe the participants’ characteristics and diagnostic features of nail psoriasis; use standard validated nail scores and patient-reported outcomes; be long enough to report efficacy and safety; and include more details of effects on nail features. Accessing Cochrane content in multiple languages. Several therapies with modest efficacy have been studied in nail psoriasis.
