The Relationship of Serum Trimethylamine N-Oxide Levels with Carotid Intima-Media Thickness and Disease Activity in Psoriasis Patients.

INTRODUCTION: Psoriasis is an inflammatory disease that can cause cardiovascular comorbidities. Some recent studies have indicated that impaired gut microbiota and metabolites may be associated with inflammatory diseases. OBJECTIVES: In this study, the relationship between serum trimethylamine n-oxide (TMAO, a gut bacterial metabolite) level and carotid intima-media thickness (CIMT) and disease severity in psoriasis patients was investigated. METHODS: Age- and gender-matched 73 patients and 72 healthy controls were included in the study. In both groups serum trimethylamine n-oxide(TMAO), oxidized low-density lipoprotein (ox-LDL), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride, total cholesterol, high-sensitivity C-reactive protein (hs-CRP), creatinine, aspartate aminotransferase (AST) and alanine aminotransferase(ALT) levels were recorded and the carotid intima-media thickness (CIMT) was measured by B-mode ultrasonography by a cardiologist. RESULTS: TMAO, hs-CRP, oxidized-LDL, triglyceride and CIMT levels were statistically higher in the patient group. HDL levels were statistically higher in the control group. There was no significant difference between the two groups in terms of total cholesterol and LDL-C levels. In partial correlation analyzes in the patient group, positive correlations were observed between TMAO and CIMT, LDL-C and total cholesterol levels. Linear regression analysis showed that TMAO levels positively predicted CIMT levels. CONCLUSIONS: This study confirmed that psoriasis is a risk factor for the development of cardiovascular disease and that elevated serum TMAO levels in these patients indicate the presence of intestinal dysbiosis. Furthermore, TMAO levels were found to be a predictor of the risk of developing cardiovascular disease in psoriasis patients.

A study on relationship between androgenetic alopecia and cardiovascular risk using high sensitivity C-reactive protein and galectin-3 in men with early onset baldness.

OBJECTIVE: In this study, the objective was to evaluate the cardiovascular and metabolic effects in men with male pattern alopecia beginning before 30 years of age. METHODS: Total of 81 people (41 androgenetic alopecia (AGA) and 40 healthy individuals) were included in the study. Twenty-four-hour ambulatory blood pressure (ABP) measurement, high sensitive C-reactive protein (hsCRP), galectin-3 were studied. Hamilton-Norwood scale (HNS) was used to determine the AGA types of the cases. RESULTS: The mean age in the AGA and control groups was 30.3 ± 7.5 and 30.8 ± 6.0, respectively. Twenty-four-hour ABP measurements, hsCRP, and galectin-3 were similar in both groups. There was a positive correlation between HNS grade with age, BMI, triglyceride levels and fasting blood glucose levels in individuals with AGA. Similarly, there was a positive correlation between HNS grade with daytime pulse wave velocity and night-time reflection magnitude. A significant positive correlation was determined between hsCRP with BMI and waist circumference, and between galectin-3 with BMI, waist circumference, hip circumference, HOMA-IR in individuals with AGA. CONCLUSIONS: This study shows that AGA patients are similar to the normal population in terms of insulin resistance or metabolic syndrome components. However, hsCRP and galectin-3 appear to be associated with cardiovascular disease risk factors in individuals with AGA.

Infantile Eosinophilic Pustular Folliculitis: A Case Report.

BACKGROUND: Infantile eosinophilic pustular folliculitis (I-EPF) is a rare disease characterized by pruritic vesicles and sterile pustules on the erythematous surface of the scalp and facial localization, usually seen in the neonatal period. It is essential to show the presence of dense eosinophils in the diagnosis of pustules. Histopathological examination of the hair follicles by eosinophils infiltration is determined. AIM: Here, we reported a 5-month-old baby boy diagnosed infantile eosinophilic pustular folliculitis. PATIENT: A 5-month-old baby boy was consulted to our polyclinic by his family because of pustules on the scalp, face, and neck developing in two week after birth. In dermatological examination, the pustular lesions of 1-2 mm in diameter on the scalp, face, and neck on an erythematous background were determined. RESULTS: There was no growth in the culture taken from the pustule. In the laboratory tests of the patient; upon detection of eosinophilia in the hemogram. The eosinophil count at the patient's first admission was 1.48 K/µl. (0.05 0.50). Eosinophil count was 0.02 K/µl after treatment. It was decreased. The patient was evaluated for other pustular dermatoses. In the differential diagnosis of the patient; causing bacterial/non-bacterial pustulosis were included. Bacterial culture was negative. CONCLUSION: Eosinophilic folliculitis defines as a group of papulopustular diseases with unknown etiology characterized histologically by eosinophilic infiltrates. First, Ofuji reported a female patient with recurrent follicular pustules and peripheral eosinophilia as a variant of folliculitis in 1965. Its etiopathogenesis is not clearly known. In the differential diagnosis of EPF includes the other pustular lesions of the newborn such as erythematoxicum neonatarum, transient neonatal pustular dermatosis, infantile acropustulosis, scabies, dermatophytosis, and langerhans cell histiocytosis. Treatment options includes topical corticosteroids and calcineurin inhibitors, antihistamines, systemic antibacterial and anti-inflammatory agents, and dapson.

Evaluation of pregnancy-associated plasma protein-A and some inflammation markers for atherosclerosis in psoriasis patients.

INTRODUCTION: Psoriasis is a common, chronic inflammatory disease of the skin. Although its relationship with cardiovascular risk factors is one of the main causes of mortality, the association between psoriasis and cardiovascular events is controversial. AIM: The aim of this study is to measure the levels of hs-CRP and pregnancy-associated plasma protein-A (PAPP-A) related to atherosclerosis in patients with moderate-severe psoriasis and to evaluate their possible association with disease severity. MATERIAL AND METHODS: This study included 45 moderate-severe psoriasis patients without additional risk factors for cardiovascular disease and 45 healthy individuals as a control group. RESULTS: Serum PAPP-A levels in both groups were given as two different variables, detectable and non- detectable, based on a value of 0.004 U/lL. When PAPP-A levels were compared, there was no statistically significant difference between the groups. CONCLUSIONS: The use of the PAPP-A test in the evaluation of early-stage atherosclerosis in moderate-severe psoriasis patients who do not have additional risk factors for cardiovascular diseases may not be sufficient.

Pyoderma gangrenosum with thymoma and myasthenia gravis: A case report.

Pyoderma gangrenosum (PG) is a rare, neutrophilic dermatosis which is characterized by painful, necrotic ulcer with violaceous border that heals with cribriform scar. Although the etiopathogenesis of PG is not known exactly, it can be triggered by many factors such as genetics, autoimmune, pathergy phenomenon, drugs, and paraneoplastic. It is frequently associated with autoimmune pathogenesis such as inflammatory bowel disease and rheumatologic disease. It can also be associated with hematological or solid organ malignancies, and then, it is called paraneoplastic PG. The association of PG with myasthenia gravis and thymoma has not been previously reported. In our case, these three diseases with a common paraneoplastic pathogenesis were seen together and the coexistence of the three diseases is rare. Treatment of PG should be decided according to the severity, spread of the lesions, concomitant disease, medical condition, and tolerance of the patient. The purpose of treatment is to control the lesions and related diseases for a long time with minimal side effects. Mycophenolate mofetil treatment was used safely and successfully for both generalized MG and PG in our case.

Successful treatment of delayed pressure urticaria with 300 mg of omalizumab every 14 days.

Delayed pressure urticaria is a rare form of chronic inducible urticaria characterized by erythematous-painful plaques that develop in areas of the skin exposed to prolonged pressure. Its treatment is very difficult, and its response to antihistamines is variable. Cases of delayed pressure urticaria, which have been completely controlled with the use of omalizumab in recent years, have been reported.

Assessment of ADMA, IMA, and Vitamin A and E Levels in Patients with Acne Vulgaris.

BACKGROUND: Acne vulgaris is a common skin disease in adolescents known to be associated with oxidative stress. However, the number of studies in which oxidative stress and antioxidants are evaluated together is limited. AIMS: In this study, we aimed to investigate L-arginine/nitric oxide (NO) pathway metabolites, ischemia-modified albumin (IMA), and vitamin A and E levels in patients with acne and its association with disease severity. PATIENTS/METHODS: Ninety patients with acne and 30 healthy adults were included in the study. The serum levels ofL-arjinin, L-arginine metabolites, IMA, and vitamins A and E measured in the patient and control groups. RESULTS: Asymmetric dimethylarginine (ADMA), LNG -monomethyl-L-arginine (L-NMMA) and symmetric dimethylarginine (SDMA), and IMA levels were significantly higher in the patients with acne than in the control group (P Ë‚ .05). The L-arginine/ADMA ratio and citrulline and vitamin A levels were significantly lower in patients with acne than those of the controls (P Ë‚ .05). ADMA and IMA plasma levels were increased in parallel with the disease severity (P Ë‚ .05). L-arginine/ADMA ratio, L-arginine, citrulline, and vitamin A plasma levels decreased as the disease became severe (P Ë‚ .05). Although L-arginine and vitamin E levels were lower in the patient group compared to the control group, the difference was not statistically significant (P Ëƒ .05). CONCLUSION: These results suggest that IMA and L-arginine-NO pathway associated with ischemia and oxidative stress may play an important role in the pathogenesis and progression of acne vulgaris.

Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis in Children With Non-Hodgkin Lymphoma.

The aim of this study is to evaluate the clinical and laboratory findings of pediatric patients with non-Hodgkin lymphoma (NHL) who developed Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Between 2006 and 2018, the medical records of child patients with NHL who developed SJS and TEN were reviewed retrospectively. SJS/TEN developed in 7 of 70 patients with NHL (10%). The pathologic subgroups of the patients with SJS/TEN were ALK-negative anaplastic large cell lymphoma (n: 3), Burkitt lymphoma (n: 2), lymphoblastic lymphoma (n: 1), and primary mediastinal B-cell lymphoma (n: 1). Five patients had TEN, 1 patient had SJS/TEN, and 1 patient developed only SJS. In 5 patients, both steroids and intravenous immunoglobulin were administered for treatment, and clinical improvement was achieved in 3 of these patients. Only steroid treatment was used for 1 patient, whereas for the other patient, intravenous immunoglobin was preferred. In addition, N-acetylcysteine treatment was administered for these 2 patients. Four patients with acute renal failure died, and it was found that SJS/TEN is observed more frequently in patients with NHL in which intensive treatment protocols with high-dose methotrexate are used more than with other childhood malignant diseases. Early diagnosis and administration of appropriate and supportive treatment approaches may improve the prognosis.

Investigation of pregnancy associated plasma protein-A and neopterin levels in Behçet's patients.

Behçet's disease (BD) is an autoimmune disease that affects many organs. We aimed to investigate the relationship between BD and these pregnancy-associated plasma protein A (PAPP-A), neopterin, and high sensitive C-reactive protein (hsCRP) parameters. The study included 57 BD patients and 54 healthy controls. After evaluating the active and inactive disease status of the patients, analyzes were performed. When comparing the patient and control groups, neopterin (111.27 ± 37.49; 76.77 ± 38.27 [nmol/L]; P < .001) and hsCRP (11.81 ± 16.8; 3.62 ± 5.06 [mg/L]; P = .001) parameters were significantly higher in patients. Neopterin (117.68 ± 41.67; 94.85 ± 14.75 [nmol/L]; P = .038) and hsCRP (14.68 ± 18.7; 4.47 ± 7.27 [mg/L]; P = .002) found different in active and inactive patients. The sensitivities of neopterin and hsCRP were also found to be high in BD (respectively 93%, 67%). PAPP-A was especially elevated in skin pathologies (P = .02) and neopterin in joint involvement (P = .03). We think that the use of neopterin and hsCRP can help in diagnosis and follow-up of BD.

The effects of isotretinoin therapy on the biliary system.

The aim of the present study was to investigate the potential effects of isotretinoin on the biliary system in patients with acne vulgaris receiving isotretinoin therapy. This was a preliminary retrospective study involving 40 patients with severe acne vulgaris who attended the dermatology clinic and were administered different doses (20 or 30 mg/day) of isotretinoin. Serum levels of AST, ALT, ALP, GGT, total bilirubin, direct bilirubin, and indirect bilirubin at the beginning and at the first month of therapy were scanned, recorded, and statistically analyzed. Total and indirect bilirubin levels at the first month of treatment in 30 patients, receiving isotretinoin at a dose of 20 mg/day, were significantly lower compared to the baseline values (p = .02 and p = .03, respectively), whereas AST and GGT serum levels were significantly higher (p = .003 and p = .006 respectively). No significant reduction in total and indirect bilirubin levels was detectable at the first month of treatment in 10 patients receiving isotretinoin at a dose of 30 mg/day; however, AST, ALP, and GGT levels were significantly elevated in these patients (p = .023; p = .004; and p = .001, respectively). To our knowledge, there is no previous study investigating the effects of isotretinoin on the biliary system, and, therefore, the present study is a preliminary one. Our findings implicate that low dose (20 mg/day) isotretinoin therapy can potentially reduce total and indirect bilirubin levels. Long-term, large-scale, prospective studies with patients receiving different doses of isotretinoin may provide more reliable information regarding the bilirubin lowering effects of isotretinoin and optimum dosing for achieving this clinical effect.

Serpentine supravenous hyperpigmentation related to carboplatin and vinorelbine chemotherapy: A case report.

Serpentine supravenous hyperpigmentation (SSH) is a unique type of chemotherapy-associated drug eruption, characterized by hyperpigmentation along the superficial venous network. Histopathology reveals an increase in melanin production without destruction of basal cells of the epidermis or dermal inflammatory infiltrate. Herein, we describe a patient who developed SSH after repeated intravenous infusions with carboplatin and vinorelbine; two medications that have been uncommonly reported in association with SSH previously.

Plasma-soluble urokinase plasminogen activator receptor (suPAR) levels in Behçet's disease and correlation with disease activity.

BACKGROUND: Soluble urokinase plasminogen activator receptor (suPAR), a new biomarker, is a soluble form of membrane-bound receptors secreted from different immune cells. The aim of the present study is to determine plasma suPAR levels in Behçet's disease and their correlation with disease activity. METHODS: Thirty Behçet's disease patients determined according to the International Study Group criteria for Behçet's disease diagnosis and 41 healthy subjects were included in the present study. Micro-enzyme-linked immunosorbent assay was employed to obtain quantitative data. Data of both groups were statistically analyzed. RESULTS: The comparison of C-reactive protein and suPAR plasma levels of the control and Behçet's disease group revealed statistically significant differences (respectively, P = 0.003 < 0.05 and P = 0.020 < 0.05). However, plasma suPAR levels related with disease activity revealed no statistically significant differences (P > 0.05). CONCLUSION: The present study is the first study analyzing suPAR levels in Behçet's disease patients and their correlation with disease activity. However, further prospective studies with larger patient series using suPAR as a new plasma biomarker are required to diagnose and monitor Behcet's disease and to support the findings of the present study.
