A case of psoriasis successfully treated by extracorporeal photopheresis during COVID-19 pandemic.

Psoriasis is a chronic inflammatory skin disease that is characterized by well-demarcated erythematous plaques with a silver scale. Although many new and emerging therapeutic agents are often sufficient to control the disease, there is still a need for alternative treatment options in challenging cases. Extracorporeal photopheresis (ECP) has been applied to many T-cell-mediated diseases to restore immune homeostasis and treat psoriasis effectively. In this paper, we present a psoriasis patient who did not respond to methotrexate, narrowband ultraviolet B, or acitretin. Because of a diagnosis of non-Hodgkin lymphoma, the patient had contraindications for cyclosporine, fumaric acid esters, and biologics but achieved remission with a total of 12 sessions of ECP in two and a half months. Although exacerbation was recorded after polymerase chain reaction (PCR) confirmed coronavirus 2019 (COVID-19) disease infection at the end of the first month, scores from the psoriasis area severity index (PASI) and dermatological life quality index (DLQI) were regressed significantly within two and a half months. ECP seems to provide an effective and rapid response for psoriasis and should be considered for psoriasis patients who fail to respond or have contraindications to existing treatments.

Cyclosporin in dermatology: A practical compendium.

Cyclosporine A (CYA) belongs to calcineurin inhibitor family, which has the ability to selectively suppress T cells. Owing to its immune-modulatory effects, it had been in use for graft vs host diseases and organ transplant rejection for many years, but in dermatology, it was first approved for use in 1997 in the treatment of psoriasis. Other off-label indications for skin diseases include atopic dermatitis, chronic spontaneous urticaria, lichen planus, pyoderma gangrenosum, alopecia areata, granuloma annulare, and several others. A thorough search of Medline-PubMed database, Google Scholar, and Uptodate was performed for evidence-based and peer-reviewed information. We have summarized the use of cyclosporine in dermatological diseases with respect to its, dosage, safety considerations, and monitoring guidelines. Furthermore, brief overview of its pharmacology, drug interactions, use in pregnancy, and lactation has been discussed. Despite of its common adverse effects like nephrotoxicity and hypertension, cyclosporine offers good safety profile when used in skin diseases. Decision to start cyclosporine therapy is individualized and it should be based on analysis of risk vs benefit. Nevertheless, CYA is preferred over other immunosuppressants in dermatology because of early therapeutic response and less myelosupression. This article offers concise but detailed summary of this beneficial immune-suppressive agent in skin diseases.

Cyclosporine A plus low-dose steroid treatment in COVID-19 improves clinical outcomes in patients with moderate to severe disease: A pilot study.

BACKGROUND: COVID-19 pandemic causes high global morbidity and mortality and better medical treatments to reduce mortality are needed. OBJECTIVE: To determine the added benefit of cyclosporine A (CsA), to low-dose steroid treatment, in patients with COVID-19. METHODS: Open-label, non randomized pilot study of patients with confirmed infection of SARS-CoV-2 hospitalized from April to May 2020 at a single centre in Puebla, Mexico. Patients were assigned to receive either steroids or CsA plus steroids. Pneumonia severity was assessed by clinical, laboratory, and lung tomography. The death rate was evaluated at 28 days. RESULTS: A total of 209 adult patients were studied, 105 received CsA plus steroids (age 55.3 ± 13.3; 69% men), and 104 steroids alone (age 54.06 ± 13.8; 61% men). All patients received clarithromycin, enoxaparin and methylprednisolone or prednisone up to 10 days. Patient's death was associated with hypertension (RR = 3.5) and diabetes (RR = 2.3). Mortality was 22 and 35% for CsA and control groups (P = 0.02), respectively, for all patients, and 24 and 48.5% for patients with moderate to severe disease (P = 0.001). Higher cumulative clinical improvement was seen for the CsA group (Nelson Aalen curve, P = 0.001, log-rank test) in moderate to severe patients. The Cox proportional hazard analysis showed the highest HR improvement value of 2.15 (1.39-3.34, 95%CI, P = 0.0005) for CsA treatment in moderate to severe patients, and HR = 1.95 (1.35-2.83, 95%CI, P = 0.0003) for all patients. CONCLUSION: CsA used as an adjuvant to steroid treatment for COVID-19 patients showed to improve outcomes and reduce mortality, mainly in those with moderate to severe disease. Further investigation through controlled clinical trials is warranted.

Practical approach to monitoring and prevention of infectious complications associated with systemic corticosteroids, antimetabolites, cyclosporine, and cyclophosphamide in nonmalignant hematologic diseases.

Corticosteroids constitute a first-line therapy for adults and children suffering from nonmalignant immune-mediated hematologic diseases. However, high disease relapse rates during the tapering period or upon drug discontinuation result in long-term corticosteroid use that increases the risk of infection. This same concept applies to other immunosuppressive agents, such as antimetabolites, calcineurin inhibitors, and cyclophosphamide. Corticosteroids are associated with a length-of-treatment and dose-dependent risk for infection. Screening and antimicrobial prophylaxis against tuberculosis, hepatitis B, Strongyloides stercoralis, and Pneumocystis jirovecii pneumonia (PJP) might be indicated in patients who are scheduled to be on high-dose corticosteroids for >4 weeks (>30 mg of prednisone-equivalent dose [PEQ]) or in patients chronically treated (≥8 weeks of continuous or intermittent corticosteroid use) with moderate doses (≥15 to <30 mg PEQ). Antimetabolites (azathioprine, mycophenolate) increase the risk of progressive multifocal leukoencephalopathy (PML); however, other opportunistic infections and viral reactivation have also been reported. In case of new onset of neurological symptoms, PML needs to be considered, and an urgent neurology consultation should be obtained. Cyclophosphamide-induced myelosuppression can lead to serious infections related to neutropenia. PJP prophylaxis should be considered with combination therapy of cyclophosphamide and corticosteroids until a PEQ dose ≤ 5 mg/d is reached. Data on infectious risk when cyclosporine is used in patients with nonmalignant hematologic diseases are lacking. Discontinuation of any immunosuppressive agent during an episode of infection is recommended. In all patients, adherence to an age-based immunization schedule is appropriate.
