Pemphigus in the eastern region of Turkey.

INTRODUCTION: Pemphigus refers to a group of rare autoimmune vesiculobullous diseases with high morbidity and mortality, mainly affecting the skin and the mucosae. AIM: To evaluate the incidence of pemphigus in the Eastern region of Turkey by analysing the clinical characteristics of the patients including the drugs used in the treatment and their side-effect profiles and dosing schedules, duration of treatment, length of hospital stay, and the characteristics of the lesions. MATERIAL AND METHODS: The retrospective study included 130 pemphigus patients who were admitted to the in- and out-patient dermatology clinics at the University Medical School between January 2005 and October 2017. Age, gender, length of hospital stay, localization of the lesions, initial and maintenance dosages, treatment-related complications, comorbidities, family history, and smoking status were recorded for each patient. RESULTS: The 130 patients included 62 (47.69%) men and 68 (52.31%) women, of which 73 (56.15%) patients had a smoking history. The annual incidence rate of pemphigus was 1.036/100,000 population and pemphigus vulgaris (PV) was the most common clinical subtype of pemphigus in our patients (n = 122; 93.85%). The most common side effect of the treatment was oral candidiasis, followed by Cushingoid appearance. CONCLUSIONS: The results indicated that the incidence of pemphigus is remarkably high in the Eastern region of Turkey and the associated factors including lifestyle changes should be taken into mind when considering these patients.

Clinic experience in discoid lupus erythematosus: a retrospective study of 132 cases.

INTRODUCTION: Lupus erythematosus (LE) is an autoimmune disease characterized by a broad range of cutaneous manifestations. Discoid LE (DLE) is the most common chronic manifestation of LE. Literature reviews show that there are a limited number of large-series studies investigating DLE. Additionally, there is still no consensus on the etiological factors of DLE such as sun exposure and smoking. AIM: To evaluate the clinical and demographic characteristics of patients with DLE. MATERIAL AND METHODS: The study included patients who were hospitalized in the inpatient and outpatient clinics at the Dermatology Department. Age, gender, treatment method, history of smoking, antinuclear antibody positivity, progression to systemic lupus erythematosus (SLE), photosensitivity, and laboratory findings were recorded for each patient. RESULTS: The study included 132 patients comprising 67 (50.8%) men and 65 (49.2%) women. A family history was found in 3.8%, SLE was detected in 5.3%, and photosensitivity was revealed in 50.0% of the patients. ANA positivity was found in 23.7%, a history of smoking was revealed in 61.4%, and chronic sun exposure was detected in 42.4% of the patients. CONCLUSIONS: Discoid LE, though identified long ago, remains unelucidated and there are very few studies in the literature reporting on DLE. The results indicated that smoking and chronic UV exposure are important risk factors for DLE. Moreover, although ANA positivity was high in our patients, the rate of progression to SLE was remarkably low. The results also showed that, contrary to common belief, there is no female preponderance in DLE.

Effects of omalizumab therapy on peripheral nerve functions: short observational study.

INTRODUCTION: Peripheral neuropathy (PN) is a common neurological condition causing symmetrical and diffuse damage in nerves. The etiology of PN includes systemic diseases, toxic exposure, medications, infections, and hereditary diseases. Omalizumab is a humanized monoclonal anti-IgE antibody that exerts its activity by binding to free IgE in circulation. AIM: To investigate the relationship between omalizumab and peripheral neuropathy. MATERIAL AND METHODS: The study included 30 patients who underwent omalizumab therapy (Xolair) due to the diagnosis of chronic urticaria. A detailed neurological and physical examination was performed in each patient both before and 3 months after the therapy. Electrophysiological examination was also performed using a Medelec Synergy instrument. RESULTS: The 30 patients included 8 (26.7%) men and 22 (73.3%) women with a mean age of 37.5 ±14.14 years. No serious side effect of the medication was detected in any patient although local wound irritation occurred in 3 (10%) patients. Moreover, no change occurred in the pre-treatment Neuropathy Symptom Score (NSS) or Neurological Disability Score (NDS) of the patients and no pathological values that could result in neuropathy were observed during motor/sensory nerve conduction. However, significant changes were detected in the sensory and motor components of the nerves with regards to pre- and post-treatment values. CONCLUSIONS: Omalizumab therapy caused no peripheral neuropathy in any of our patients but altered the latency, amplitude, and velocity values of the peripheral nerves.

Evaluation of pentraxin 3 level and cardiac functions in psoriatic children.

Psoriasis is a chronic inflammatory disorder affecting the skin, nails, and joints. Its lifetime prevelance has been estimated to be at 1% to 3%. This study was designed to examine the association between serum pentraxin 3 (PTX3) and cardiovascular function in psoriatic children. Thirty-three children who were diagnosed with psoriasis, and 29 healthy children, between 4 and 18 years of age, were included in the study. Both patient and control group was evaluated by the pulsed wave tissue doppler imaging (TDI) echocardiography as well as with conventional Doppler echocardiography (CDE). PTX3 values of the groups were evaluated. There was no difference between cases and controls for age (9.67±3.72, 9.60±2.84 years, p=0.916, respectively). In evaluation of the left ventricle (LV) CDE; A wave, isovolumic relaxation time (IVRT) and myocardial performance index (MPI) were significantly higher in the study group (p < 0.05). Ejection time (ET) was significantly lower in the study group compared to the control group (p < 0.05). In evaluation of LV TDI; Deceleration time (DT`), IVRT`, E/E` and MPI` were found to be significantly higher in the study group (p < 0.05). In addition to, E`, E`/A` and ET` were siginificantly lower in study group. PTX3 level was significantly higher in the study group compared to the control group (p=0.009) (Table III). However, no correlation was found between PTX3 level and cardiovascular parameters. In conclusion; both doppler echocardiography and PTX3 may be useful tools for the screening of cardiovascular (CV) risk in these patients. Psoriasis itself may be an independent risk factor for cardiac dysfunction in the pediatric population.

Assessment of Heavy Metal and Trace Element Levels in Patients with Telogen Effluvium.

BACKGROUND: Despite a multitude of studies, etiology of primary chronic telogen effluvium (TE) remains incompletely understood. Essential heavy metals are associated with beneficial effects in humans as well as in other living organisms. However, they may lead to toxic effects when the exposure exceeds the higher tolerable limits. We wanted to assess the heavy metal and trace element levels in patients with chronic TE. MATERIALS AND METHODS: A total of 40 subjects with chronic TE were included in the study, and 30 healthy women served as control. General and dermatological examinations were taken up in all individuals. Those patients with positive hair pull test were evaluated with the help of a trichogram. The presence of >20% telogen hair as documented by trichogram was a requirement for the study inclusion. UNICAM-929 spectrophotometry device was used for determining serum trace element and heavy metal concentrations. RESULTS: In spite of an absence of significant differences in terms of average Zn concentration, weight, or height between patients and controls, significant differences were noted for Cd, Fe, Mg, Mn, Pb, Co, and Cu (P <0.05). CONCLUSION: Our results suggest that heavy metals may play a causative role in the development of chronic TE. However, contrary to previous reports, zinc did not appear to play an important etiological role, while these patients had elevated serum iron levels.
