Evaluation of the relationship of digital phototrichogram findings of patients with diffuse hair loss with blood TSH, ferritin and vitamin B12 levels.

OBJECTIVE: Telogen effluvium (TE) is a type of alopecia that is frequently seen in women. Among factors resulting in hair loss, many reasons such as endocrine diseases, nutrition disorders, stress, anemia, low ferritin levels, vitamin B12 deficiency, and thyroid diseases are found. A digital phototrichogram is one of the non-invasive methods of diagnosis in the evaluation of alopecia. In this study, it was aimed to compare biochemical parameters of female patients with diffuse hair loss with phototrichogram findings. METHODS: 108 female patients with diffuse hair loss were included in the study. Patients were divided into two groups: acute and chronic TE, and a hair pull test was applied. Total blood count, blood biochemistry, iron, iron binding capacity, ferritin, thyroid stimulating hormone (TSH), sT3, sT4, folic acid, and vitamin B12 levels were examined. The telogen/anagen ratios and hair densities of patients were determined with a phototrichogram. RESULTS: The serum biochemical parameters (aspartate aminotransferase, alanine aminotransferase, urea, creatinine), TSH, sT3, sT4, and folic acid levels of patients were within normal limits. Telogen ratio, anagen ratio, hair density, number of shed hairs, family history, blood ferritin, TSH, and vitamin B12 levels were found to be similar between groups having acute and chronic TE. In our study, while mean anagen and telogen ratios with trichoscan were similar to literature data, no statistically significant correlation was determined between patients' ages and examined trichoscan findings (p>0.05). The hair pull test positivity of patients with chronic TE was higher compared to patients with acute TE (p<0.05). In patients with positive hair pull tests, the telogen ratio and hair density were found to be higher. In the group with <40 ng/mL ferritin level, the mean telogen ratio was detected to be significantly higher than the mean anagen ratio (p<0.05). No significant correlation was determined between vitamin B12 and TSH levels in patients and phototrichogram findings (p>0.05). CONCLUSION: The findings of this study showed that ferritin has an important role in diffuse hair loss, and the phototrichogram method is an auxiliary method for the physician in the diagnosis of TE.

The effect of IL17 and IL23 inhibitors on hematological parameters and C-reactive protein in psoriasis patients.

INTRODUCTION: In the quest for objective biomarkers for psoriasis, the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), C-reactive protein (CRP), and mean platelet volume (MPV) have been used to assess disease severity, treatment efficacy, and follow-up in psoriasis, and their relationship with the Psoriasis Area Severity Index (PASI) has been investigated. PURPOSE: The evaluation of pre-treatment, 3rd and 6th-month levels of NLR, PLR, MPV, and CRP along with PASI scores in psoriasis patients treated with secukinumab, ixekizumab, risankizumab, and guselkumab. MATERIALS AND METHODS: In our study, 83 patients aged 18 and over, who were followed up with moderate-severe plaque type psoriasis vulgaris and psoriatic arthritis and received secukinumab, ixekizumab, risankizumab, and guselkumab treatment in the chronic skin diseases clinic of Firat University Faculty of Medicine Hospital between January 2019 and 2023, were evaluated retrospectively. RESULTS: Post-treatment leukocyte, neutrophil, lymphocyte, platelet, CRP, and PASI values were statistically significantly lower in all biological agent groups and all patients. The post-treatment NLR value was statistically significantly higher in all patients and in the group using ixekizumab. The post-treatment PLR value was statistically significantly higher in the group using guselkumab and ixekizumab and in all patients. The post-treatment MPV was statistically significantly higher in all patients and in the group using secukinumab. No correlation was found between post-treatment PASI and other values (p > 0.05). There was no statistically significant difference between the post-treatment 6-month values among all biological agent groups. The effects of different drugs on outcomes after treatment were found to be similar (p > 0.05). CONCLUSION: Our study supports the view that MPV and CRP can be used in patients with psoriasis using IL17 and IL23 inhibitors, while NLR and PLR parameters derived from blood count may not be used to evaluate treatment response, contrary to other studies.

Effect of isotretinoin treatment on inflammatory and hematological parameters in patients with acne vulgaris.

PURPOSE: Although the inflammatory and anti-inflammatory effects of isotretinoin (ISO) treatment in patients with acne vulgaris have been discussed in the literature in recent years, no sensitive and specific marker has been found in studies so far. Neutrophil/HDL (high-density lipoprotein) (NHR), lymphocyte/HD L(LHR), platelet/HDL (PHR), and lymphocyte/monocyte (LMR) are new biomarkers related to inflammation. Triglyceride/HDL (TG/HDL), LDL/HDL, and total cholesterol/HDL have been shown to be cardiometabolic risk factors predicting both cardiovascular disease risk and metabolic risk, rather than just a simple dyslipidemia scale. To our knowledge, the relationship between these parameters and ISO treatment has never been studied before. We aimed to evaluate the immuno-inflammatory response of ISO treatment in patients with acne vulgaris with NHR, LHR, PHR, LMR, TG/HDL, LDL/HDL, and total cholesterol/HDL parameters. MATERIALS AND METHODS: In this study, 153 patients who received oral ISO treatment for at least 3 months with a diagnosis of moderate-severe acne vulgaris were evaluated retrospectively. Patients were given oral isotretinoin at a dose of 0.5-1 mg/kg. Pre and post-treatment leukocyte (WBC), neutrophil (NE), lymphocyte (LY), platelet (PLT), red cell distribution width (RDW), plateletcrit (PCT), neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), mean platelet volume (MPV), monocyte/lymphocyte (MLR), LMR, total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, MHR, NHR, LHR, PHR, TG/HDL, total cholesterol/HDL, LDL/HDL parameters were evaluated. RESULTS: It was found that post-treatment WBC and MPV values increased statistically significantly; NLR, neutrophil, and PCT values, on the other hand, decreased significantly (p < 0.05). No statistically significant change was detected in PLR, MLR, LMR, MHR, NHR, LHR, PHR, lymphocyte, monocyte, platelet, and RDW parameters (p > 0.05). It was determined that post-treatment total cholesterol, triglyceride, VLDL, and LDL levels increased statistically significantly; however, the HDL level decreased significantly (p < 0.05). Levels of total cholesterol/HDL, TG/HDL, and LDL/HDL were also found to increase statistically significantly (p < 0.05). CONCLUSION: Our study suggests that the MPV and NLR ratio as biomarkers can be used as indicators of atherosclerosis-related inflammation due to ISO treatment, but the MHR, NHR, LHR, PHR, MLR, LMR ratios cannot be used. Moreover, we believe that the ratios of TG/HDL, LDL/HDL, and total cholesterol/HDL offer a new contribution as indicators of cardiovascular risk and systemic inflammation related to ISO treatment.

Effect of different production methods on quality parameters of Hatay Künefe cheese.

We investigated four different production methods of Künefe cheese, emphasizing their industrial importance. The four methods used fresh Künefe cheese (FKC), salted Künefe cheese (SKC), Boru type Künefe cheese (BKC) and culture-added processed Künefe cheese (CPKC), all used in the production of Künefe, a syrupy dessert unique to the Middle East. FKC was produced as a result of curd formation from raw milk with rennet and then the fermentation of curd. SKC was manufactured using the salting method in addition to FKC production. BKC was obtained using the dry cooking process with emulsifying salts applied to cheese curd. CPKC was produced by applying heat treatment to raw milk and using starter culture before adding rennet that was different to Boru-type Künefe cheese. The composition, color, meltability, texture and sensory properties of the Künefe cheeses were examined. As a result of statistical analysis, it was determined that the effect of different production methods on the composition, meltability, texture (except springiness and cohesiveness) and sensory properties was significant in all cheeses (P < 0.05). CKPC was the most appropriate cheese in various properties.

Phytocontact dermatitis due to Ranunculus arvensis: Report of three cases.

Ranunculus arvensis (R. arvensis) is a member of the Ranunculaceae family and is often used by advanced age women living in rural areas for the topical treatment of arthralgia, myalgia, hemorrhoid, and warts. Protoanemonin is a substance found in the fresh leaves of the plants from the Ranunculaceae family and leads to contact dermatitis. In this report, we present three cases that developed phytocontact dermatitis caused by the topical use of R. arvensis as an alternative treatment method for arthralgia and palmoplantar psoriasis.

The effect of pentavalent antimonial compounds used in the treatment of cutaneous leishmaniasis on hemogram and biochemical parameters.

Objective: The aim of this study was to analyze the effect of pentavalent antimonials used in the treatment of cutaneous leishmaniasis (CL) on hemogram and biochemical parameters. Material and methods: The study consisted of 168 patients diagnosed with CL after microscopic examination and treated with either systemic sodium stibogluconate (SSG) or meglumine antimonate (MA) 20 mg/kg/day for 14 days. The patients were divided into two groups as SSG and MA patients. Neutrophil count, leukocyte count, lymphocyte count, hemoglobin concentration, platelet count, amylase, lipase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen and serum creatinine levels were compared before and on the 14th day of the treatment. Results: There was a statistically significant decrease in the neutrophil, lymphocyte, leukocyte, platelet counts, and hemoglobin and blood urea nitrogen levels on the 14th day of the treatment when compared to the pre-treatment values. A statistically significant increase was found in the ALT, AST, amylase and lipase levels. No significant change was found in the serum creatinine levels. Conclusion: According to the results of our study, pentavalent antimonials given standard doses in the treatment of CL can lead to an increase in the pancreatic enzymes and transaminases and bone marrow suppression. We do not recommend any change in the treatment if these conditions are not corroborated by clinical findings.
