The potential association between herpes zoster and COVID-19 vaccination.

Objective: Little is known about the dermatological manifestations associated with COVID-19 vaccines. The aim of the study was to determine how many cases of herpes zoster (HZ) occurred after COVID-19 vaccination and to see if there was a possible link. Methods: A retrospective cohort study was performed by archive scan between 2016 and 2020, and between January 2021 and January 2022. Patients diagnosed with HZ were enrolled and their demographic and medical history including age, sex, previous systemic disease, history of COVID-19 vaccination prior to HZ symptom onset, COVID-19 vaccine type as mRNA or inactive, time to HZ onset after vaccination, and number of COVID-19 vaccines before HZ symptom onset were recorded. Results: The average annual number of HZ cases from 2016 to 2020 was 271, but the number of HZ cases in 2021 was 338, reflecting an increase. The number of HZ patients with a known history of COVID-19 vaccination in 2021 was 117 and their mean age was 57.6 ± 14.2 years. Females were 59.8% (n = 70) and 28.2% (n = 33) had chronic diseases. A positive history of COVID-19 vaccination was present in 35.9% (n = 42) of HZ patients, 11.1% (n = 13) had received mRNA vaccines and 24.8% (n = 29) had received inactive COVID-19 vaccine. Mean time to HZ after COVID-19 vaccination was 24.6 ± 16.3 days. Conclusion: An important finding of this study is the high rate (35.9%) of COVID-19 vaccination among people diagnosed with HZ. As COVID-19 vaccination may be associated with reactivation of varicella zoster virus, the vaccination history should be obtained in HZ patients.

Relationships Between Disease Severity and the C-reactive Protein/Albumin Ratio and Various Hematological Parameters in Patients With Acne Vulgaris.

OBJECTIVE: Acne vulgaris, an inflammatory disease, was investigated in this study with the claim that the C-reactive protein (CRP)/albumin ratio and some hematological parameter ratios have the potential to be used as inflammatory markers to monitor disease severity and prognosis. METHODS: A descriptive cross-sectional study was conducted with two groups of patients aged 18-65 years, 61 patients diagnosed with acne vulgaris and 35 healthy control patients, and routine hemogram and biochemical parameters were compared. The Global Acne Severity Index was used to determine the severity of acne vulgaris. RESULTS: The median age of acne patients was 22.0 (IQR=5.0) and the median age of healthy volunteers was 30.0 (IQR=14.0). There were 75.4% (n=46) women in the acne group and 77.1% (n=27) women in the control group. Among the acne patients, 42.6% (n=26) had mild acne, and 41% (n=25) had moderate acne severity. A significant difference was found between the study groups in terms of CRP/albumin ratio, CRP, monocyte/lymphocyte ratio (MLR), lymphocyte/albumin ratio (LAR), and monocyte/CRP ratio (MCR) according to laboratory test results and calculated test ratios (p<0.05). The area under the curve (AUC) value of the CRP/albumin ratio in the receiver operating characteristic (ROC) analysis between the acne and control groups was 0.660, and its cut-off value was found to be 0.236 with 68.6% sensitivity and 68.9% specificity. CONCLUSION: This study is the first to compare the CRP/albumin ratio with the severity of acne vulgaris in the literature. CRP/albumin ratio and MCR may serve as inflammatory markers that can be used to monitor the severity of acne vulgaris.

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

OBJECTIVE: 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. MATERIALS AND METHODS: 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. RESULTS: 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). CONCLUSION: 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.

Etiological causes in patients with acute urticaria and angioedema: A cross-sectional study.

BACKGROUND: Acute urticaria and angioedema are emergency dermatological conditions associated with various etiologic factors. OBJECTIVE: To determine the etiological causes in patients with acute urticaria and angioedema, and to investigate whether more than one etiological cause was present, along with the patients' laboratory values. METHODS: The study was conducted in a tertiary hospital with one center. Etiological causes and laboratory parameters in 284 patients diagnosed with acute urticaria and angioedema were retrospectively studied. RESULTS: A total of 284 patients were included in the study. The mean age of the patients was 42.7 ± 15.6 years, where 163 (57.4%) were women and 121 (42.6%) were men. Acute urticaria and angioedema occurred together in 149 (52.5%) patients. At least one precipitating factor among the predisposing risk factors was present in 220 (77.5%) patients, and more than one precipitating factor was found in 51 (18%) patients. Medication use was found in 157 (55.3%) patients and infection in 54 (19%). The development of urticaria after food consumption was noted in nine (3.2%) individuals. A history of infection and medication intake was present in 50 (17.6%) patients. A joint history of food consumption and medication intake was present in only one patient. Elevated C-reactive protein level was found in 178 (62.7%) patients and elevated anti-streptolysin O titer in 41 (14.4%) patients. Vitamin B12 deficiency was found in 116 (40.8%) patients and vitamin D deficiency in 254 (89.4%). CONCLUSION: Acute urticaria and angioedema may occur as a result of multiple etiological factors, in which different triggers may be present simultaneously.

A multicentre prospective analysis of the incidence of pemphigoid diseases in Turkey.

BACKGROUND: The differentiation between the pemphigoid diseases is essential for treatment and prognosis. In Turkey, data on the incidence of these diseases are insufficient. Our aim in this study is to determine the incidence, demographics and clinical characteristics associated with diseases of the pemphigoid group. METHODS: We prospectively analysed 295 patients with pemphigoid who visited dermatology clinics of tertiary referral hospitals in 12 different regions of Turkey within a year. The diagnosis was based on clinical, histopathological, direct immunofluorescence (DIF) and serological (multivariant enzyme-linked immunosorbent assay [ELISA], indirect immunofluorescence and mosaic-based BIOCHIP) examinations. Clinical and demographic findings, aetiological factors and concomitant diseases observed in the patients were recorded. RESULTS: A total of 295 (female/male ratio: 1.7/1) patients with pemphigoid were diagnosed in 1-year period. The overall incidence rate of pemphigoid diseases was found to be 3.55 cases per million-years. The ratio of pemphigoid group diseases to pemphigus group diseases was 1.6. The most common pemphigoid type was bullous pemphigoid (BP, 93.2%). The others were epidermolysis bullosa acquisita (3.1%), pemphigoid gestationis (2.4%), linear IgA disease (1%) and mucous membrane pemphigoid (0.3%). The most common (26.8%) possible trigger of the bullous pemphigoid was gliptin derivative drugs. The most common concomitant diseases with pemphigoid were cardiovascular (27.8%) and neurological diseases (23.7%). CONCLUSIONS: This study showed that the increased frequency of bullous pemphigoid reversed the pemphigoid/pemphigus ratio in Turkey. Further studies are warranted regarding the reasons for this increase.

Psoriasis vulgaris and autoimmune polyendocrine syndrome type I: a case report.

Autoimmune polyglandular syndrome (APS) is a rarely diagnosed condition characterized by a combination of two or more organ-specific autoimmune diseases and divided into a very rare juvenile (APS type I) and a relatively common adult type (APS II-IV). The major components of APS-I are hypoparathyroidism, adrenal failure, and mucocutaneous candidiasis. In addition to the classic triad, many other autoimmune diseases could be associated with the syndrome. We report an adolescent patient with psoriasis vulgaris and APS-I.
