Currently, psoriasis patients are advised to follow their standard therapeutic regimen, and are advised to be vaccinated against Covid-19. However, the data about the antibody responses, induced by the various kinds of SARS-CoV-2 vaccines in psoriasis patients who require systemic immunosuppressive treatment is scant. In this case report, we describe antibody responses induced by COVID-19 vaccine, in a 26-year-old male patient with psoriasis being treated with anti-TNF biotherapy, adalimumab biosimilar every two weeks. The patient was vaccinated against COVID-19, according to the national protocol. He experienced three episodes of symptomatic COVID-19. His first and second exposures did not result in antibody production. After the third episode of COVID-19, The SARS-CoV-2 anti-spike antibody (IgG) was more than 100 Ru/mL (ELISA; ≥8 Ru/mL is considered positive), and SARS-CoV-2 neutralizing antibody (total) was more than 40 micg/mL (ELISA; ≥2.5 micg/mL is considered positive). This is the first case with weak antibody response to vaccination and multiple episodes of COVID infection in a psoriatic patient with adalimumab biosimilar. However, we cannot assume causality due to the treatment.

Patients with psoriasis are more likely to experience depression and suicidality compared to non-psoriatic patients, though systemic therapies have been shown to improve depressive symptoms. It is unclear whether or not biologic or oral agents are more effective at improving such depressive symptoms in psoriasis patients, however. We aimed to determine an estimate of the odds of incident depression in psoriasis patients on different systemic therapies by performing a cross-sectional analysis of postmarketing data. The reporting odds ratio (ROR) for 15 different systemic agents was calculated using reports from the Food and Drug Administration Adverse Events Reporting System (FAERS). After excluding brodalumab and apremilast due to high risk of reporting bias, we found oral agents were associated with a significantly higher ROR of depression compared to biologics (OR = 2.42, 95% confidence interval: 1.93-3.04). These results suggest biologics may be more effective at reducing incident depression than oral agents. Future controlled trials are needed to confirm these findings.

Background: Hereditary hypotrichosis simplex is a rare genetic hair disease that affects the scalp. Failure to grow normal hair in terms of length and density is the main complaint of patients. Diagnosis usually established by exclusion of other congenital hair and other ectodermal disorders. Till now, no satisfactory treatment was used for the condition.Report: A 14 year old patient with hypotrichosis simplex was treated with combined platelet rich plasma injection and topical minoxidil 2% with marked improvement.Conclusion: While no satisfactory treatment presents for this condition, the use of platelet rich plasma injection can add new hope for hypotrichosis simplex patients.

Background: Cell-based therapies are popular in the field of reconstructive surgery. The stromal vascular fraction (SVF), comprised of mature adipocytes or blood, reportedly has a regenerative effect; however the mechanism remains unclear. This study aimed to prove the viability and effectiveness of using SVF in scar treatment.

Methods: This prospective double-blind study involved 20 patients who visited an outpatient clinic for 2 years, from July 2016 to July 2018, and underwent scar revision for traumatic or surgical scars. After scar revision surgery performed by a single surgeon, patient scars were divided into experimental and control sides. The subcutaneous layer of the experimental and control sides were injected with 0.1 mL/cm of SVF and normal saline, respectively. Each side was evaluated using the Patient and Observer Scar Assessment Scale (POSAS) before and six months after the surgery.

Results: Of the 20 patients who underwent scar revision surgery and SVF treatment, 4 dropped out for personal reasons. In 11 of 12 POSAS items, the experimental side showed significant improvements compared to the control side.

Conclusions: Although more research is needed, autologous SVF is a valuable source of regenerative medicine that can be swiftly and inexpensively prepared from human fat tissue.

Background: Dose reduction of biologics for psoriasis is applied in daily practice, although guidelines are lacking. Striving for clear criteria is important, as it leads to a consistent application of dose reduction.

Objective: To achieve consensus on criteria for biologic dose reduction in psoriasis patients with stable and low disease activity.

Methods: An online Delphi procedure (eDelphi) was conducted. Dutch dermatologists were invited to participate in a maximum of 3 voting rounds. Proposed statements were selected based on literature review and included criteria for the application of dose reduction and dosing schedules. Biologic dose reduction was defined as 'application of injection interval prolongation'. Proposed statements were rated using a 9-point Likert scale; consensus was reached when ≥70% of all voters rated 'agree' (7-9) and <15% rated 'disagree' (1-3).

Results: A total of 27 dermatologists participated and reached a consensus on 15 recommendations over 2 voting rounds. Agreed statements included criteria for dose reduction eligibility, criteria for dose reduction (dis)continuation, and dosing schedules for adalimumab, etanercept, and ustekinumab. Based on the eDelphi outcomes, an algorithm fit for implementation in current practice was developed.

Conclusions: Recommendations of this national consensus process can guide clinicians, and consequently their patients, toward consistent application of biologic dose reduction.

Background: Programmed cell death-1 (PD-1) inhibitors represent an effective treatment option for advanced cutaneous squamous cell carcinoma (cSCC). However, solid organ transplant (SOT) recipients with cSCC have traditionally been excluded from clinical trials.

Objective: To assess the safety and efficacy of PD-1 inhibitors for stage III-IV cSCC in SOT recipients.

Materials & methods: A systematic review was performed using the PubMed, EMBASE, and Scopus databases.

Results: We identified 21 articles describing 33 SOT recipients (26 kidney, four liver, two lung, and one heart) with stage III-IV cSCC treated with PD-1 inhibitors. Eleven patients (33.3%) experienced allograft rejection. Of the 25 cases with iRECIST scores, twelve patients (48.0%) had a complete response (CR), eight (32.0%) showed a partial response (PR), three (12.0%) progressive disease, and two (8.0%) stable disease (SD). Including patients without available iRECIST scores, 21 patients (63.6%) showed tumor response. Eleven patients died, with six (54.5%) due to tumor progression and one (9.1%) due to allograft rejection after foregoing dialysis.

Conclusion: PD-1 inhibitors demonstrate efficacy for advanced cSCC and confer a risk of allograft rejection in SOT recipients, requiring careful assessment of risks and benefits. If anti-PD-1 therapy is pursued, use of mTOR inhibitors, prophylactic steroids, and donor-derived cell-free DNA monitoring may mitigate the risk of rejection.
