Nail Disorders in Patients Living with HIV Coinfected with Monkeypox: A Clinical Study in 69 Mexican Cases

Introduction: Several infectious diseases can present nail manifestations, which may be useful for diagnosis and prognosis, and only a few reports have been made regarding monkeypox (mpox). The objective of this study was to describe the clinical characteristics of nail alterations in patients living with HIV coinfected with mpox. Methods: A prospective, cross-sectional study included patients living with HIV/AIDS, coinfected with mpox. We examined all 20 nails in search of nail plate alterations. Patients were divided into two groups, with and without nail disease, and the CD4 count was noted according to the Centers for Disease Control and Prevention (CDC) classification. A χ2 or Fisher’s exact test for qualitative variables and Mann-Whitney U and Kruskal-Wallis tests with post hoc Bonferroni test for quantitative variables were used to compare them. Data were analyzed with the SPSS Statistics 25 software. Results: Sixty-nine patients were included. The frequency of nail involvement was 58%. Papulonodular lesions were the most frequent type identified, with 21 cases (30.4%). A significant difference was observed between patients with nail disease versus median CD4 count (160 vs. 700/mm3; p = 0.002) and median HIV viral load (45,000 vs. 900/mL; p = 0.009). When comparing the characteristics of the nail lesions with the CDC Classification System for HIV infection by the CD4 count, a significant difference was observed in foot involvement, splinter hemorrhages, papulo-nodular lesions, anonychia, onychomadesis, acute paronychia, and nail bed ulcer-atrophy (p < 0.05). Conclusions: The frequency of nail lesions is high in patients living with HIV coinfected with mpox. In addition, they tend to be more destructive in patients with lower CD4 counts and higher viral loads.

The Frequency of Association of Nail Involvement and Psoriatic Arthritis in Psoriasis Patients.

While the relationship between psoriatic arthritis and skin findings is well-known in patients with psoriasis, the relationship between psoriatic arthritis and nail involvement is less known. In this study, it was aimed to examine the frequency of association between nail involvement and psoriatic arthritis in patients with psoriasis. Our study is a retrospective observational study. It was conducted with 250 regis- tered patients who applied to the dermatology polyclinic and clinic of our university hospital. The follow-up forms of the patients were scanned retrospectively and the findings were recorded. The average age of the 250 patients evaluated in this study was 39.62 ± 9.30, and 133 (53.2%) of them were women. The frequency of nail involvement in psoriasis patients was determined to be 36.8% (n=92) and the frequency of arthritis was determined to be 8.8% (n=22). Nail involvement was statisti- cally significantly more common in those with arthritis, and nail involvement was present in all of those with arthritis (P < .001). Nail involvement was significantly more common in those with only arthralgia (P < .001). A significantly higher average of nail psoriasis severity index was found in those with both joint and nail involvement compared to those with only nail involvement (P < .001). There was no statistically significant difference in terms of psoriasis area severity index average (P=.235). Proximal and distal interphalangeal arthralgia and sacroiliac arthralgia were found significantly more frequently in those with nail involvement than in those without nail involvement (respectively P = .007 and P < .001). There was no statistically signifi- cant relationship between nail involvement with the presence of arthritis and the clinical type (respectively P = .288 and P = .955). Joint involvement and nail involvement in patients with psoriasis are closely related, and we think that nail and joint involvement in psoriasis patients should be evaluated together.

Narrative Review of Drug-Associated Nail Toxicities in Oncologic Patients.

Nail toxicity represents one of the most common cutaneous adverse effects of both classic chemotherapeutic agents and new oncologic drugs, including targeted treatments and immunotherapy. We aimed to provide a comprehensive literature review of nail toxicities derived from conventional chemotherapeutic agents, targeted therapies (EGFR inhibitors, multikinase inhibitors, BRAF and MEK inhibitors) and immune checkpoint inhibitors (ICIs), including clinical presentation, implicated drugs and approaches for prevention and management. Retrieved literature from PubMed registry database was reviewed to include all articles published up to May 2021 relevant to the clinical presentation, diagnosis, incidence, prevention, and treatment of oncologic treatment-induced nail toxicity. The internet was searched for relevant studies. A wide spectrum of nail toxicities is associated with both, conventional and newer anticancer agents. The frequency of nail involvement, especially with immunotherapy and new targeted agents remains unknown and patients with different cancer types receiving different regimens may develop the same nail disorder, whereas patients with the same type of cancer under the same chemotherapeutic treatment may develop different types of nail alterations. The underlying mechanisms of the varying individual susceptibility and the diverse nail responses to various anticancer treatments need further investigation. Early recognition and treatment of nail toxicities can minimize their impact, allowing better adherence to conventional and newer oncologic treatments. Dermatologists, oncologists and other implicated physicians should be aware of these burdensome adverse effects in order to guide management and prevent impairment of patients' quality of life.

Uncovering subtle nail involvement in lichen planus with dermoscopy: a prospective, controlled study.

IntroductionThere are very few studies investigating the dermoscopic aspect of nail involvement in lichen planus and these studies described dermoscopic features of only clinically visible nail involvement in lichen planus.AimTo reveal subtle dermoscopic nail findings in patients with lichen planus.Material and methodsThe study included 40 patients with lichen planus and 40 healthy volunteers. All fingernails of the patients and healthy volunteers were examined by a handheld dermoscope and the findings detected were recorded. The patients were grouped by age, gender, disease duration and extent of the disease. The statistical analysis was performed using Chi square test.Results82.5% of the patients and 17.5% of the healthy volunteers showed at least one dermoscopic nail finding. The frequency of multiple splinter haemorrhage (p < 0.05), multiple leukonychia (p < 0.05), longitudinal erythronychia (p < 0.05), prominent hyponychial vascular structures (p < 0.05) and onycholysis (p < 0.05) observed in the patients group was statistically significant. The other findings included distal short longitudinal lines, onychorrhexis, solitary splinter haemorrhage and solitary punctate leukonychia and showed no statistically significant differences between the two groups.ConclusionsTo the best of our knowledge, this is the first study focusing on uncovering subtle nail involvement in lichen planus. The presence of dilated hyponychial vascular structures in lichen planus was first described in the present study. It can be concluded that the frequency of nail involvement in lichen planus is more than known. Dermoscopic imaging of the nails of all patients with lichen planus may help establish early diagnosis and treatment to avoid permanent nail damage.

The Clinical Spectrum of Psoriatic Arthritis

Epidemiologic, clinical, radiologic and serologic evidence suggests that psoriatic arthritis is a specific entity and not the coincidental occurrence of 2 common diseases, psoriasis and rheumatoid arthritis. Psoriatic arthritis may be defined as psoriasis associated with inflammatory arthritis (peripheral arthritis or spondylitis or both) and usually a negative serologic test for rheumatoid factor. Clinical characteristics of the disease include: almost equal distribution between males and females; peripheral arthritis involving only a few small joints in asymmetical fashion; involvement of distal interphalangeal joints; sausage digits; arthritis mutilans; ankylosing spondylitis; goutlike onset; and higher frequency of nail involvement than occurs in uncomplicated psoriasis. The rash may present with arthritis, or, equally, may precede or succeed joint involvement. With regard to pain and disability, the prognosis in psoriatic arthritis is better than in rheumatoid arthritis.
