Investigation of the relationship between inflammatory blood parameters and seborrheic dermatitis

Evaluation of epicardial fat tissue thickness in patients with seborrheic dermatitis

Seborrheic dermatitis is a common inflammatory skin disease that primarily affects the scalp, face, and body folds. Recent studies have shown that seborrheic dermatitis may be associated with inflammation and cardiometabolic conditions. We aimed to investigate this relationship in our study. Fifty patients with seborrheic dermatitis who came to the dermatology outpatient clinic and completely healthy patients in a similar age group were included in the study. Echocardiographic findings and heart rates of the patient and control groups were recorded on previously prepared forms. The mean epicardial fat tissue thickness of the patient group was 0.72 ± 0.04, while the mean of the control group was 0.62 ± 0.05, and this difference was considered significant (P < 0.001). There was no significant difference between the patient and control groups in terms of left atrium (p = 0.759), interventricular septum thickness (p = 0.252), and heart rate (p = 0.835). Epicardial fat tissue loses its protective role in pathological processes and plays a role in cardiovascular diseases, especially coronary artery disease, in inflammatory processes. In this respect, SD patients should be carefully monitored for long-term, especially for coronary artery disease.

Relationship between circulating white blood cell count and inflammatory skin disease: a bidirectional mendelian randomization study

Observational studies have shown a strong association between circulating white blood cell counts (WBC) and inflammatory skin diseases such as acne and psoriasis. However, the causal nature of this relationship is unclear. We performed a two-way two-sample Mendelian randomization (MR) analysis to investigate potential causal relationships between leukocytes and inflammatory skin diseases. The circulating white blood cell count, basophil cell count, leukocyte cell count, lymphocyte cell count, eosinophil cell count, and neutrophil cell count data were obtained from the Blood Cell Consortium (BCX). The data for inflammatory skin disorders, including acne, atopic dermatitis (AD), hidradenitis suppurativa (HS), psoriasis, and seborrheic dermatitis (SD), were obtained from the FinnGen Consortium R10. The primary analysis utilized inverse variance weighting (IVW) along with additional methods such as MR-Egger, weighted mode, and weighted median estimator. To assess heterogeneity among instrument variables, Cochran's Q test was employed, while MR-Egger intercept and MR-PRESSO were used to test for horizontal pleiotropy. IVW demonstrated that an elevated monocyte count was significantly associated with a decreased risk of psoriasis (OR = 0.897, 95% CI: 0.841-0.957, P = 0.001, FDR = 0.016). Additionally, an increased eosinophil count was causally associated with a higher risk of AD (OR = 1.188, 95% CI: 1.093-1.293, P = 0.000, FDR = 0.002). No inverse causal relationship between inflammatory skin disease and circulating white blood cell count was found. In conclusion, this study provides evidence that increased monocyte count is associated with a reduced risk of psoriasis and that there is a causal relationship between increased eosinophil counts and an increased risk of AD. These findings help us understand the potential causal role of specific white blood cell counts in the development of inflammatory skin diseases.

Is seborrheic dermatitis associated with early-stage osteoarthritis?

Seborrheic dermatitis (SD) and osteoarthritis involve similar factors in their pathogenesis. Both of these diseases are associated with an increased frequency of metabolic syndrome and underlying systemic inflammation. This study evaluated the thickness of the distal femoral cartilage using ultrasonography in patients with SD. The study enrolled 60 patients with SD (19 females and 41 males, mean age: 34.07 ± 12.56 years) and 60 controls matched for age and sex (20 females and 40 males, mean age: 35.08 ± 12.78 years). Ultrasonography was used to measure the distal femoral cartilage thickness (FCT) of the right medial condyle, right lateral condyle, right intercondylar area, left medial condyle, left lateral condyle, and left intercondylar area. FCT values at all points were significantly higher in patients with SD than in the controls (P < .05). Further, all FCT values were significantly higher in patients with moderate SD than in those with mild SD (P < .001). A strong positive correlation was observed between disease severity and FCT measured at right medial condyle (r = .7, P < .001), right lateral condyle (r = .749, P < .001), right intercondylar area (r = .79, P < .001), left medial condyle (r = .624, P < .001), and left intercondylar area (r = .703, P < .001). Further, a moderately positive correlation was observed between disease severity and FCT measured at left lateral condyle (r = .581, P < .001). Increased FCT in patients with SD might be an early indicator of osteoarthritis. However, further studies, especially those evaluating older patients with SD, are required to support our findings.

C-Reactive Protein: Pathophysiology, Diagnosis, False Test Results and a Novel Diagnostic Algorithm for Clinicians

The current literature provides a body of evidence on C-Reactive Protein (CRP) and its potential role in inflammation. However, most pieces of evidence are sparse and controversial. This critical state-of-the-art monography provides all the crucial data on the potential biochemical properties of the protein, along with further evidence on its potential pathobiology, both for its pentameric and monomeric forms, including information for its ligands as well as the possible function of autoantibodies against the protein. Furthermore, the current evidence on its potential utility as a biomarker of various diseases is presented, of all cardiovascular, respiratory, hepatobiliary, gastrointestinal, pancreatic, renal, gynecological, andrological, dental, oral, otorhinolaryngological, ophthalmological, dermatological, musculoskeletal, neurological, mental, splenic, thyroid conditions, as well as infections, autoimmune-supposed conditions and neoplasms, including other possible factors that have been linked with elevated concentrations of that protein. Moreover, data on molecular diagnostics on CRP are discussed, and possible etiologies of false test results are highlighted. Additionally, this review evaluates all current pieces of evidence on CRP and systemic inflammation, and highlights future goals. Finally, a novel diagnostic algorithm to carefully assess the CRP level for a precise diagnosis of a medical condition is illustrated.

Hematological parameters in patients with acnes

OBJECTIVE

To compare complete blood count (CBC) parameters and inflammatory factors in the patients with different grade of acne vulgaris and healthy controls.

METHODS

A total of 20 patients were enrolled in this study. Patients were divided into mild group and moderate-to-severe group based on the acne severity, and compared to controls. Inflammatory factors (TNF-α, IL-6, IL-8, and IL1-α) detected by ELISA and complete blood count parameters (MPV, NLR, dNLR, PLR, LMR, and SII) obtained by routine blood tests were compared among the three group.

RESULTS

All CBC parameters were not significantly elevated in patients with acne compared to healthy controls. However, the present studies have found that the inflammatory factors in acne patients were significantly elevated relative to healthy controls, and increase with the acne grade.

CONCLUSIONS

Inflammatory factors are convenient parameters to show inflammatory response to acne vulgaris, and may be a new clinical method for judging the acne grades of objectively. Considering the use of antibiotic, we believe that this metric worth further study.

Evaluation of the effectiveness of triamcinolone solution diluted with normal saline for the treatment of seborrheic dermatitis

Background and Aim

Seborrheic dermatitis is a common inflammatory disease for which various treatments have been proposed. The main purpose of this study was to determine the effectiveness of 80-mg Triamcinolone solution diluted with 0.1% normal saline for the treatment of seborrheic dermatitis in adults.

Methods

For this study, 120 patients with seborrheic dermatitis were considered. After obtaining written and informed consent, patients were treated with 80 mg of Triamcinolone diluted with 0.1% normal saline. To evaluate the effectiveness of Triamcinolone treatment, the scoring index (SI) and the level of patient satisfaction were evaluated at 2 and 4 weeks after the start of treatment and also 4 weeks after the end of treatment.

Results

The results of the study showed that 61.67% (74 patients) were satisfied with "good" to "very good" for the Triamcinolone treatment to seborrheic dermatitis. Based on the findings of the study, it was found that the SI before treatment was equal to 2.45 ± 7.45, which after 2 weeks after treatment, this index decreased by 61.6% (SI: 2.86 ± 1.94). In addition, the SI decreased to 88.6% (SI: 0.85 ± 1.02) after 4 weeks.

Conclusion

Considering the high decrease in SI, increasing patient satisfaction and observing a low number of cases with recurrence of the disease by Triamcinolone treatment method, it can be concluded that injection of Triamcinolone 80 mg diluted with 0.1% normal saline can be effective and efficient for the treatment of seborrheic dermatitis.
