Sleep quality in patients with chronic spontaneous urticaria and relation with Orexin-A, leptin, and ghrelin.

Background: Sleep can be affected in patients with chronic spontaneous urticaria (CSU). The mechanisms of sleep regulation remain poorly understood. Orexin-A, a neuroexcitatory peptide, plays a role in coordinating sleep-wake states. Ghrelin and leptin are involved in sleep regulation through the orexin system. Objective: The effects of orexin-A, ghrelin, and leptin on sleep quality in patients with CSU have not been investigated. We aimed to determine the effects of CSU on sleep quality and the association between serum orexin-A, ghrelin, and leptin levels, and sleep quality in patients with CSU. Methods: Thirty-three patients with CSU and 34 sex- and age-matched controls were included in the study. Serum orexin-A, leptin, and ghrelin levels, and the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) scores were measured in patients with CSU and in the controls; also used were the chronic urticaria quality-of-life questionnaire score and the urticaria activity score used for 7 consecutive days. Results: Median (minimum-maximum) orexin-A, leptin, and ghrelin levels in patients were 385 pg/mL (90-495 pg/mL), 3.1 ng/mL (0-21.2 ng/mL), and 701.8 pg/mL (101.9-827.7 pg/mL), respectively. Median serum orexin-A and leptin levels were higher in the patients compared with the controls (p < 0.001 and p = 0.012, respectively), whereas the median serum ghrelin levels were similar to the controls (p = 0.616). The serum orexin-A level was positively correlated with ghrelin (r = 0.298, p = 0.014), PSQI sleep quality (r = 0.356, p = 0.003), and ESS (r = 0.357, p = 0.003). Conclusion: Serum orexin-A is associated with sleep quality in patients with CSU. Further studies are needed to elucidate the role of ghrelin and leptin on sleep quality in patients with CSU.

Importance of the C-Reactive Protein to Albumin Ratio in the Diagnosis and Prognosis of Mycosis Fungoides.

INTRODUCTION: The C-reactive protein to albumin ratio (CAR) lately has demonstrated as a prognostic factor and an indicator of disease activity, severity and prognosis in solid organ malignancies and inflammatory diseases. However, the effects of CAR have not been investigated in mycosis fungoides (MF) patients yet. OBJECTIVES: This study aimed to determine the potential role of CAR as a diagnostic and a prognostic indicator in MF. METHODS: We retrospectively investigated the electronic medical records of 97 patients with MF admitted to the Dermatology Clinic of Health Sciences University, Diskapi Yildirim Beyazit Training and Research Hospital between January 2014 and December 2020. In total, 60 patients with MF were enrolled in the study. CAR was evaluated, patient and control group. Also, the other clinicopathological factors including age, lactate dehydrogenase, stage of disease, beta-2-microglobulin levels, and sedimentation levels were evaluated. RESULTS: The median value of CAR was 0.85 (0.10-7.51) in the patient group, whereas it was 0.39 (0.0-1.11) in the control group (P < 0.001). Patients with disease progression (N = 16, 13M, 3 F) had a median value of CAR 0.84 (0.10-7.51) and the median value of CAR (N = 44) was 0.86 (0.12-4.57) in the group of patients with stable disease. The CAR value had no prognostic significance (P > 0.05). CONCLUSIONS: There is no association between the CAR and progression in the stage in MF patients. But the CAR is significantly higher in patients with MF than in the control group. The CAR can be a guide for us in cases where we have difficulty in diagnosing.

Elucidating the role of T-Reg related cytokines: serum transforming growth factor beta and interleukin-35 in alopecia areata.

Previous studies demonstrated that Th1 cytokines like IL-2, IL-12 and IFN-γ have initiatory role in alopecia areata (AA) and positive correlation with disease severity. They informed that serum levels of Th17 cytokines, IL-17, IL-22, IL-23 increased in active AA patients and corelated, particularly IL-17, with disease severity. In recent reports it was showed the balance between Th17 and Treg cells is crucial for maintaining tolerance to self-antigens, and an imbalance towards Th17 may contribute to the development of autoimmune diseases like AA. But research on serum Treg markers in AA is limited. It was aimed to investigate whether the Treg cells have a role in the pathogenesis of AA analyzing the serum levels of Treg cytokines IL-35 and TGF-ß in the patients with AA. 42 AA patients and 38 healthy controls were enrolled. Patient demographics, clinical data, disease severity assessed by Severity of Alopecia Tool (SALT) scores were recorded. Serum samples were collected and analyzed for TGF-ß and IL-35 levels using ELISA kits. The cytokine levels in both groups were statistically compared. Their relation with parameters of demographic and severity of disease was evaluated. The patient and control groups had no statistically significant difference, there was 71.4% males and 28.6% females in patient group, while the control group had 63.2% males and 36.8% females, Severity analysis classified 18 patients with mild AA, 19 with moderate AA, and 5 with alopecia totalis/areata universalis. While TGF-ß levels exhibited no significant difference between groups, IL-35 levels were significantly elevated in AA patients (p = 0.002). Logistic regression identified IL-35 as a significant parameter influencing disease status (OR = 1.055). Correlation analysis revealed a weak positive correlation between patient age and IL-35 levels (r = 0.436; p = 0.004). Notably, IL-35 levels displayed a significant decrease in individuals with antinuclear antibody (ANA) positivity. No correlations were identified between cytokine levels and disease severity, prognosis, or disease activity. Elevated IL-35 levels suggest that IL-35 and specific Treg cell subsets can play a role in AA pathogenesis. The nuanced roles of TGF-ß and IL-35 highlight the need for comprehensive studies to interpret their implications in the complex immunopathogenesis of AA. These findings open avenues for further research, positioning IL-35 as a prospective target for investigating and potentially intervening in AA pathogenesis.

Can the mucosal attacks of Behçet's disease be predicted?

The primary objective of this study was to investigate the association between disease activity and serum and salivary procalcitonin (Pct) levels in patients with Behçet's disease (BD). The study included patients diagnosed with BD and age-matched healthy volunteers (N: 48, N: 32). Serum and salivary Pct levels were quantified using enzyme-linked immunosorbent assay (ELISA) in the laboratories of Diskapi Yildirim Beyazit Training and Research Hospital. No significant disparity was observed in serum and salivary Pct levels between the patient and control groups (p > 0.05). Furthermore, there was no noteworthy correlation between disease activity and serum and salivary Pct values (p > 0.05). However, the serum Pct level in patients with active oral ulcers was significantly elevated compared to those without active oral ulcers (p: 0.003). Serum Pct emerges as a valuable marker for monitoring oral aphthous ulcer attacks within the patient population.

Evaluation of psoriasis patients with long-term topical corticosteroids for their risk of developing adrenal insufficiency, Cushing's syndrome and osteoporosis.

PURPOSE: In this study, we will investigate the possible side effects of psoriasis patients using long-term topical corticosteroids (TCS) such as adrenal insufficiency, Cushing's Syndrome (CS) and osteoporosis and determine how these side effects develop. MATERIAL AND METHODS: Forty-nine patients were included in the study. The patients were divided into two groups based on the potency of the topical steroid they took and the patients' ACTH, cortisol and bone densitometer values were evaluated. RESULTS: There was no significant difference between the two groups regarding the development of surrenal insufficiency, CS and osteoporosis. One patient in group 1 and 4 patients in group 2 were evaluated as iatrogenic CS. ACTH stimulation tests of these patients in group 2 showed consistent results with adrenal insufficiency, while no adrenal insufficiency was detected in the patient in Group 1. Patients who used more than 50g of superpotent topical steroids per week compared to patients who used 50g of superpotent topical steroids per week. It was identified that patients who used more than 50g of superpotent topical steroids had significantly lower cortisol levels, with a negatively significant correlation between cortisol level and the amount of topical steroid use (p < .01).Osteoporosis was detected in 3 patients in group 1 and 8 patients in Group 2. Because of the low number of patients between two groups, statistical analysis could not be performed to determine the risk factors. CONCLUSIONS: Our study is the first study that we know of that investigated these three side effects. We have shown that the development of CS, adrenal insufficiency and osteoporosis in patients who use topical steroids for a long time depends on the weekly TCS dosage and the risk increases when it exceeds the threshold of 50 grams per week. therefore, our recommendation would be to avoid long-term use of superpotent steroids and to choose from the medium-potent group if it is to be used.

The Impact of the Initial Phase of the COVID-19 Pandemic on Patients With Autoimmune Bullous Diseases.

Introduction The follow-up of patients with autoimmune bullous diseases (AIBDs) was temporarily interrupted during the initial phase of the COVID-19 pandemic due to restrictions in healthcare services, given the high contagiousness and rapid spread of SARS-CoV-2. Our objective was to assess the impact of the initial phase of the COVID-19 pandemic on the treatments and disease activity of AIBD patients. Methods We conducted a telephone survey of patients with AIBDs who had been regularly followed up in our hospital prior to the onset of the pandemic. A structured questionnaire that we designed was used. This questionnaire comprised questions examining the following issues between March and June of 2020: patients' follow-up, treatment, COVID-19 infection status, and changes in disease activity. Results Thirty-nine patients were included in the study. Among those, 26 (66.7%) were immunosuppressed. The frequency of follow-up for 37 patients (94.9%) changed significantly (p<0.001): 28 patients (71.8%) did not visit the hospital, and 26 of them (92.9%) did not communicate at all. The treatment for 10 patients (25.6%) was altered, either by their physician or by themselves. Disease activity reactivated in patients who altered their own treatments. There was only one patient (2.6%) who contracted COVID-19. Conclusions Documenting this period revealed that some patients were negatively impacted by the pandemic initially. The most significant contributing factor was the interruption of patient-physician communication.

A Case of Circumscribed Palmar or Plantar Hypokeratosis and a Mini-review of the Literature.

ABSTRACT: Circumscribed palmar or plantar hypokeratosis (CPPH) is a new dermatologic disorder that firstly defined Pérez A et al in 2002. Since that time, further cases of CPPH have been reported by different authors in different countries. We report a 69-year-old Turkish woman who presented with asymptomatic, erythematous patches on the thenar region of the left hand and on the second left finger. Skin biopsy showed histological features of CPPH. In this article, it was emphasized that CPPH may be seen more frequently than expected and the clinical and pathological features of this disease with suspected malignant transformation should be known.

Genetic Etiology of Ichthyosis in Turkish Patients: Next-generation Sequencing Identified Seven Novel Mutations

Objective: Ichthyosis is a clinically heterogeneous group of genodermatoses characterized by widespread drying and scaling of the skin. It is also a genetically heterogeneous disorder, and 67 genes associated with the disease have been identified to date. However, there are still undiscovered genes causing the disease. Methods: We investigated 19 Turkish patients from 17 unrelated families using clinical exome sequencing or multigene panel screening. Results: Sixteen likely pathogenic or pathogenic variants were detected in 13 unrelated patients. We identified "variant of unknown significance" alteration in only one patient. Seven novel variants were identified in ABCA12, ALOX12B, and ALOXE3. The most commonly mutated gene was TGM1, followed by ABCA12 and ALOX12B. Conclusions: Because of the wide genetic variability of ichthyosis, it is difficult to diagnose the disease quickly and definitively. The clinical use of next-generation sequencing (NGS) methodologies is beneficial in the diagnostic approach to ichthyosis and genetic counseling. This study highlights the underlying molecular cause of ichthyosis by determining the mutational spectrum in a cohort of 19 patients. This study is the first and largest research from Turkey using NGS that highlights all ichthyosis subtypes.

Is there a link between alopecia areata and gut?

BACKGROUND: There may be an association between increased intestinal permeability and the progression of alopecia areata (AA). OBJECTIVE: The present study aimed to investigate the role of intestinal permeability in the etiopathogenesis of AA and its association with the severity of the disease. METHODS: Serum zonulin levels of 70 patients with AA who were not receiving any systemic treatment and of 70 healthy control subjects were measured. RESULTS: The median serum zonulin level in the patient group (46.38 ng/mL) did not differ significantly from that in the control group (50.34 ng/mL) (p = 0.828). Moreover, there was no significant relationship between serum zonulin levels and the severity of the disease (p = 0.549). LIMITATIONS: The present study had a cross-sectional design, and it did not include patients with alopecia totalis (AT) or alopecia universalis (AU). CONCLUSION: We did not observe an increase in intestinal permeability secondary to zonulin expression in patients with AA. However, in order to generalize this result to all patients with AA, serum zonulin levels need to be evaluated in studies including more patients with severe disease, AT, and AU.

Drug-Induced Histiocytoid Sweet Syndrome: Two Cases With Levofloxacin and Amoxicillin-Clavulanate.

ABSTRACT: Histiocytoid Sweet syndrome (HSS) is an uncommon histologic variant of Sweet syndrome (SS). HSS can be distinguished from the classic SS with an infiltrate of histiocyte-like immature myeloid cells rather than dense neutrophilic infiltration, although the clinical features are similar. Previous studies have shown that the risk of hematologic malignancy is significantly higher in HSS compared with classic SS. To lesser extent, HSS is also associated with infections, inflammatory diseases, and drugs, particularly with antineoplastic agents as well. Here, we report a case of 2 patients with an abrupt onset of erythematous, tender plaques accompanied by fever, with that revealed similar histopathologic and immunohistochemical features, whom had a history of antibiotic use. Clinicopathologic correlation led to diagnosis of drug-induced HSS, associated with the use of levofloxacin and amoxicillin-clavulanate, respectively. Both patients were then successfully treated with systemic corticosteroid therapy, and neither of them had recurrence during the period of 24-month follow-up.

Correlation study between clinical classification and disability index in a holistic evaluation of acne severity and impact in Turkey.

BACKGROUND: This study provides a comparison between disease severity observed by inspectors and the disease burden assessed by patients is scanty in acne study. METHODS: In a multicenter prospective hospital-based study, modified Comprehensive Acne Severity Scale (mCASS) and Cardiff Acne Disability Index (CADI) were employed to grade disease severity and to determine the quality of life, respectively. The average of the mCASS and CADI scores, with range at 0-25, was termed as Acne Severity and Impact Grading System (ASIG). RESULTS: In 1331 evaluated patients (mean: 21,51±4,93 years), including 306 men and 1025 women, an overall significant, positive correlation was found between ASIG and mCASS (r=0.862), or CADI (r=0.686), respectively (P=0.001 each). Adult women with back acne and adolescent with décolleté expressed greater concern (higher CADI) than the clinical severity (lower mCASS). The overall prevalence of acne in décolleté area, including neck, was 32.3%. CONCLUSIONS: Discrepancies in the acne severity between self-perception and objective evaluation exist in certain subgroups of patients. Décolleté acne deserves special attention in clinical assessment.

Secukinumab may be remedy for systemic amyloidosis findings secondary to hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a chronic relapsing inflammatory disease of follicular epithelium; many comorbidities occur that disrupt the quality of life of patients. Amyloidosis is one of them. We present a case with systemic amyloidosis secondary to HS and responding positively to secukinumab therapy. Secukinumab may also be an important option for amyloidosis findings in HS patients.

Ischemic modified albumin as a new biomarker in predicting oxidative stress in alopecia areata

Background/aim: Results show that oxidative stress is a pathophysiologic factor for alopecia areata (AA); however, the markers used can be confounding. Thus, we aimed to investigate the role of oxidative stress in the pathogenesis of AA through an evaluation of ischemia-modified albumin (IMA); other markers of the oxidant/antioxidant system, such as SOD, CAT, GSH-ST, and MDA; and contributing clinical risk factors. Materials and methods: The usefulness of IMA as a new marker for oxidative stress was compared with that of other markers and evaluated in patients with AA. Results: The mean serum level of IMA was of higher statistical significance in AA patients than in the control group (IMA: 0.57 ± 0.01 vs. 0.52 ± 0.02 ΔABSU, P < 0.0001). IMA (P = 0.03, OR = 25.8, 95% CI = 1.4­482.7) was found to be an independent predictor of oxidative stress in patients with AA. Increased severity of AA was found as an independent risk factor for IMA. Conclusion: Long-lasting disease, male sex, >1 site of involvement of disease, and increased severity of disease were correlated with increased oxidation. Presence of AA, male sex, and severe disease were determined to be independent risk factors for antioxidant and oxidant systems. IMA has great potential as a biomarker of oxidative stress in AA when compared to other studied biomarkers.

Evaluation of Neopterin Level and Disease Severity in Patients with Psoriasis Vulgaris Treated with Narrowband UVB.

BACKGROUND: Neopterin is a biochemical marker of cellular immunity. It has been reported that serum and urine neopterin levels increase in psoriasis and decrease with treatment. Nevertheless, assessment of a direct link between narrowband ultraviolet B (UVB) therapy and neopterin level in association with Psoriasis Area and Severity Index (PASI) scores has not been performed yet. We aimed to evaluate the serum neopterin level in patients with psoriasis treated with narrowband UVB therapy in association with disease severity. MATERIALS AND METHODS: The study included 35 patients with chronic plaque-type psoriasis who had PASI scores of >10 or below 10 but resistant to topical therapies and 30 healthy individuals. The narrowband UVB therapy was administered to the patient group (n = 35). Serum neopterin analysis was performed with an enzyme-linked immunosorbent assay method before and after treatment. RESULTS: There was statistically significant correlation between neopterin level and PASI score in the patient group (P = 0.011). The serum neopterin level was significantly increased in patients with higher PASI score. Moreover, the serum neopterin level was found to be statistically higher in severe psoriasis group (PASI score ≥10, n = 14) than the mild-moderate group (PASI score <10, n = 21) (P = 0.001). Furthermore, a significant decrease was observed according to serum neopterin level after the narrowband UVB therapy in the remaining 20 patients who were able to comply with the scheduled therapy and follow-up procedure (P = 0.026). CONCLUSION: Serum neopterin levels were found to be an useful marker for evaluating disease severity and efficacy of narrowband UVB treatment. Thus, our findings may provide a new approach with the management of disease and follow-up strategies in patients with psoriasis.

Serotonin Expression in Lichen Planus Lesions and Its Relationship with Depression/Anxiety.

BACKGROUND: Psychological factors such as stress, depression, and anxiety have been documented to contribute to the development of lesions in lichen planus (LP). OBJECTIVE: To evaluate the relationship between serotonin expression in LP lesions and depression/anxiety. METHODS: Forty patients (22 females, 18 males) with LP and 20 healthy control subjects were included in this study. The severity of LP was assessed with the palmar method (using the measurement of affected body surface area [BSA]). The depression and anxiety scores were measured with Beck's depression inventory (BDI) and Beck's anxiety inventory (BAI). The expression of serotonin was determined via immunohistochemistry in LP lesions and in the control group skin using a monoclonal antibody to serotonin. RESULTS: The skin biopsies of the LP patients had significantly higher levels of serotonin than those of the control subjects (p<0.001). In the LP patients, and there was a positive correlation between serotonin expression and LP severity (p=0.022). Based on the results from the BDI and BAI, there was a significant relationship between the severity of depression/anxiety and intensity of serotonin expression (p<0.001). CONCLUSION: Data from this study suggest that serotonin may have a possible role in the pathogenesis of LP. Further, the relationship between serotonin expression in acute cutaneous lesions and the depression/anxiety scores indicates that serotonin may be a mediator for the association of LP and depression/anxiety simultaneously. There is a need for more specific studies showing the expression of serotonin in the lichen planus to demonstrate the cause or effect.

Systemic comorbidities associated with rosacea: a multicentric retrospective observational study.

BACKGROUND: Once considered a disorder limited to the skin, rosacea is now known to be associated with systemic disorders. The aim of this study was to determine what systemic comorbidities accompany rosacea and to determine the relationship between the type, severity, and duration of rosacea, and the presence of and type of systemic comorbidities. METHODS: This retrospective multicenter study was conducted by the Turkish Society of Dermatology Acne Study Group. Thirteen dermatology clinics throughout Turkey participated in the study. A structured physician-administered questionnaire was used to collect patient demographics, clinical findings, and lifestyle data. The principal rosacea subtype, physician global assessment of severity, and duration of rosacea were recorded. Physicians recorded each participant's medical history, including current and past comorbidities, duration of any such comorbidity, and the use of medications to treat any comorbidities. RESULTS: The study included 1,195 rosacea patients and 621 controls without rosacea aged 18-85 years. As compared to the controls, more of the rosacea patients had respiratory tract, gastrointestinal system, and metabolic and hepatobiliary system disorders in a rosacea's severity- and duration-dependent manner. CONCLUSION: Clinicians must be aware of the potential for systemic comorbidities in rosacea patients, which becomes more likely as disease duration and severity increase.

Comparison of quality of life in patients with androgenetic alopecia and alopecia areata

Abstract: Background: Androgenetic alopecia is one of the most common forms of hair loss. Alopecia areata is a common autoimmune disorder which causes hair loss. It has been previously reported that both alopecia disorders can have negative effects on quality of life. However, only a few studies have compared the effects of the two disorders. Objective: The aim is to show the impact of alopecia on patients' quality of life and compare patients with androgenetic alopecia and alopecia areata. Methods: 82 androgenetic alopecia and 56 alopecia areata patients were recruited. All patients were evaluated with the Hairdex scale and dermatology quality of life instrument in Turkish (TQL), and the scores were statistically compared according to age, sex, employment and education status, and severity of illness in the two groups. Also, female patients were statistically evaluated according to whether they wore headscarves. Results: Androgenetic alopecia patients had significantly higher total Hairdex scores in terms of emotions, functioning, and symptoms, while self-confidence was significantly higher in the alopecia areata patients. No significant differences were found in stigmatization or TQL scores between groups. The Hairdex scale and TQL scores did not show differences between the groups in terms of wearing headscarves. Study limitations: The validity and reliability of the Hairdex index have not been established in Turkey. Conclusions: Based on the Hairdex scale, our findings revealed that androgenetic alopecia patients are more affected by their disorder than alopecia areata patients. Although androgenetic alopecia is common and neither life-threatening nor painful, it is a stressful disorder with increased need for improvement in the patient's quality of life.

The efficacy and safety of omalizumab in refractory chronic spontaneous urticaria: real-life experience in Turkey.

INTRODUCTION: This study used real-world data to evaluate the effectiveness and reliability of omalizumab in treating recalcitrant chronic spontaneous urticaria in Turkish patients. METHODS: Study data were collected retrospectively from eight tertiary-care hospitals in Turkey. This study included 132 patients with chronic spontaneous urticaria that were resistant to H1 antihistamine treatment in a dose up to four times the licensed dose and were treated with 300 mg/month of omalizumab for 6 months. RESULTS: The mean weekly urticarial activity score (UAS7) after omalizumab treatment improved significantly compared to the pre-treatment score (p < 0.001). Treatment response was detected primarily in the 1st and 2nd months after treatment. No significant association was observed between omalizumab's treatment effectiveness and disease-related parameters or laboratory data. The mean dermatology life quality index was 23.12 ± 6.15 before treatment and decreased to 3.55 ± 3.60 6 months after treatment (p < 0.001). No side effects were reported in 89.4% (118) of the patients. CONCLUSIONS: This study showed that UAS7 decreased significantly and quality of life improved in omalizumab-treated patients. Moreover, treatment effectiveness was mainly observed in the first 2 months after treatment. However, no association was observed between omalizumab treatment effectiveness and disease-related parameters or laboratory data.
