RESUMO

OBJECTIVES: Skin changes in acromegaly are often the first sign of the disease. The aim of this study was to describe the cutaneous findings in patients with acromegaly. In addition, a secondary aim was to investigate the possible association of these findings with remission status and concomitant endocrinopathies. DESIGN, PATIENTS, AND MEASUREMENTS: In this prospective multicenter study, 278 patients over the age of 18 years with acromegaly who were followed up in 14 different tertiary healthcare institutions were included. These patients, who were followed up by the Endocrinology Department, were then referred to a dermatologist for dermatological examination. The frequency of skin lesions was investigated by detailed dermatologic examination. Dermatological diagnosis is reached by clinical, dermatological and/or dermoscopic examination, and rarely skin punch biopsy examinations in suspicious cases. The possible association of the skin findings between remitted and nonremitted patients and with concomitant endocrinopathies were evaluated. RESULTS: The most common skin findings in patients with acromegaly in our study were skin tags (52.5%), cherry angiomas (47.4%), seborrhoea (37%), varicose veins (33%), acneiform lesions (28.8%), hyperhidrosis (26.9%) and hypertrichosis (18.3%). Hypertrichosis was significantly more prevalent in patients nonremitted (p: .001), while xerosis cutis was significantly more prevalent in patients remitted (p: .001). The frequency of diabetes mellitus and hypothyroidism was significantly higher in patients with varicose veins and seborrhoeic keratosis than those without. Additionally, the coexistence of hypothyroidism, hyperthyroidism and galactorrhea was significantly higher in patients with Cherry angioma than in those without Cherry angioma (p-values: .024, .034 and .027, respectively). The frequency of hypogonadism in those with xerosis cutis was significantly higher than in those without (p: .035). CONCLUSIONS: Cutaneous androgenization findings such as skin tag, seborrhoea, acne and acanthosis nigricans are common in patients with acromegaly. Clinicians should be aware that skin findings associated with insulin resistance may develop in these patients. It can be said that the remission state in acromegaly has no curative effect on cutaneous findings. Only patients in remission were less likely to have hypertrichosis. This may allow earlier review of the follow-up and treatment of acromegaly patients presenting with complaints of hypertrichosis. Additionally, it can be said that patients with skin findings such as cherry angioma may be predisposed to a second endocrinopathy, especially hypothyroidism. Including dermatology in a multidisciplinary perspective in acromegaly patient management would be beneficial to detect cutaneous findings earlier.

RESUMO

BACKGROUND/PURPOSE: Interferon (IFN)-a is often used in combination with psoralen plus ultraviolet A (PUVA) in patients with mycosis fungoides (MF) refractory to skin-targeted therapies in early or advanced stages. The main objective is to evaluate the effectiveness of combined PUVA and low-dose IFN-α-2a therapy in patients with early- and advanced-stage MF. METHODS: Sixty-eight patients who received a combination of PUVA twice or thrice a week and INF-a 3 MU thrice a week for at least 3 months were reviewed retrospectively. The treatment response was evaluated as complete remission (CR), partial remission, stable disease, or progression. RESULTS: At the initiation, the majority of patients (66.2%) had early-stage disease. In 27.9% of cases, this was the initial treatment administered following the diagnosis of MF. The median duration of combination therapy was 11 months. Complete remission was achieved in 45.6% of the patients with an overall response rate of 60.3%. The mean duration of response was 5 months. Complete remission was statistically significantly higher in early-stage patients (p < .05). No statistically significant correlation was observed between CR and gender, histopathological features, or laboratory parameters. In patients with CR, 80% experienced relapse, significantly higher in early-stage patients (p < .05). However, there was no significant difference in disease-free survival between early and advanced stages (p > .05). CONCLUSIONS: The study results indicated that PUVA + low-dose INF-a combination therapy was more effective in the early stage than in the advanced stage. Additionally, there was a high relapse rate after the cessation of treatment in patients who achieved CR.

RESUMO

BACKGROUND: As the majority of T-cell lymphomas lack CD20 expression, cases of mycosis fungoides (MF) exhibiting aberrant CD20 expression are exceedingly uncommon. OBJECTIVES: We aim to comprehensively evaluate the clinical, histopathological, and prognostic features of 7 patients diagnosed with CD20-positive MF. METHODS: This retrospective study examines seven cases of MF with aberrant CD20 expression. The study provides details of demographics, clinical features, histopathology and treatment outcomes. Key time points include initial diagnosis of MF, detection of CD20 expression and follow-up, with a mean follow-up of 46 months. RESULTS: Aberrant CD20-positive MF was diagnosed at an average age of 58.6 years, approximately 5.6 years after first MF diagnosis. Following CD20 detection, patients presented with advanced disease stages, requiring treatments such as chemotherapy, brentuximab vedotin, and allogeneic hematopoietic stem cell transplantation. Four patients died from lymphoma, with an average survival time of 52 months. CONCLUSIONS: Aberrant CD20 expression in MF is rare but indicates a progressive course associated with poor prognosis. This often requires systemic chemotherapy and, in certain instances, allogeneic hematopoietic stem cell transplantation. This study provides important insights into the clinical attributes, disease progression, and treatment options for MF patients with aberrant CD20 expression. Further research is necessary to validate the effectiveness of emerging therapies and enhance our understanding of the underlying mechanisms and prognostic determinants specific to this unique MF subgroup.

RESUMO

Dystrophic epidermolysis bullosa (DEB) has long been recognized as a well-known genodermatosis, caused by COL7A1 gene pathogenic variants. Isolated anonychia associated with RSPO4 gene mutation is a recently described non-syndromic autosomal recessive condition. In this family, a 13-year-old girl presented with severe epidermolysis bullosa symptoms. Family history revealed milder but similar complaints in the siblings, and anonychia affecting all nails in the mother and maternal relatives. The father did not have any signs of DEB. Genetic testing revealed heterozygous c.6127G>A (p.Gly2043Arg) variant in the COL7A1 (NM_000094.4) gene, in the proband and her affected siblings. The variant was not detected in the mother or father, prompting investigation into parental mosaicism. Detection of the variant in sperm sample suggested paternal mosaicism. Additionally, RSPO4 gene (NM_001029871.4) was sequenced in the mother and two of her affected sisters for suspected non-syndromic isolated anonychia, revealing homozygous c.79+1G>A variant. Isolated nail disease in the mother was initially thought to be the result of DDEB nails-only subtype and the DEB in the children was inherited from the mother. However, further clinical and genetic investigation showed that the condition in the patient and her siblings arose from gonosomal mosaicism in the father and the nail phenotype in the mother is a separate coincidental condition. This report aims to serve as an example for similar cases and highlight the importance of detailed genetic analysis guided by comprehensive medical history in reaching a diagnosis.

RESUMO

BACKGROUND: Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma. Skin-directed therapies, including phototherapy, are the first-line treatment modalities. Psoralen plus ultraviolet A light photochemotherapy (PUVA) is quite effective in controlling the disease; however, long-term adverse effects, particularly carcinogenesis, are the cons of this treatment. OBJECTIVE: There are various studies on the negative impact of PUVA on skin cancer in patients with autoimmune skin diseases. The data on the long-term effects of phototherapy on MF patients are scarce. METHODS: All MF cases that received PUVA alone or combined with other treatments at a single tertiary center were analyzed. This study compared the development of non-melanoma skin cancers, melanoma, and solid organ tumors in MF patients with at least 5-year follow-up data with age- and sex-matched controls. RESULTS: A total of 104 patients were included in the study. Ninety-two malignancies were detected in 16 (15.4%) patients, and six developed multiple malignancies. Skin cancers consisted of 56 basal cell carcinomas, 16 Bowen's disease, four squamous cell carcinomas, three melanomas, two basosquamous cell carcinomas, one Kaposi sarcoma, and one keratoacanthoma were found in nine (8.7%) patients. Eight patients developed three solid cancers and six lymphomas. The risk of developing skin cancer was associated with the total number of PUVA sessions (<250 vs ≥250 sessions; hazard ratio (HR) 4.44, 95% confidence interval (CI) 1.033-19.068; p = .045). 9 (13.2%) of 68 patients who had follow-ups for at least 5 years developed skin cancer. Compared to an age- and sex-matched cohort, the prevalence of new skin cancer was considerably greater (p = .009). CONCLUSIONS: Patients with MF are predisposed to develop secondary malignancies, and continual exposure to PUVA may potentiate this risk. Annual digital dermoscopic follow-up in MF patients treated with UVA is advised for early diagnosis and treatment of secondary cutaneous malignancies.

RESUMO

BACKGROUND: Vaccines that incorporate multiple SARS-CoV-2 antigens can further broaden the breadth of virus-specific cellular and humoral immunity. This study describes the development and immunogenicity of SARS-CoV-2 VLP vaccine that incorporates the four structural proteins of SARS-CoV-2. METHODS: VLPs were generated in transiently transfected HEK293 cells, purified by multimodal chromatography, and characterized by tunable-resistive pulse sensing, AFM, SEM, and TEM. Immunoblotting studies verified the protein identities of VLPs. Cellular and humoral immune responses of immunized animals demonstrated the immune potency of the formulated VLP vaccine. RESULTS: Transiently transfected HEK293 cells reproducibly generated vesicular VLPs that were similar in size to and expressing all four structural proteins of SARS-CoV-2. Alum adsorbed, K3-CpG ODN-adjuvanted VLPs elicited high titer anti-S, anti-RBD, anti-N IgG, triggered multifunctional Th1-biased T-cell responses, reduced virus load, and prevented lung pathology upon live virus challenge in vaccinated animals. CONCLUSION: These data suggest that VLPs expressing all four structural protein antigens of SARS-CoV-2 are immunogenic and can protect animals from developing COVID-19 infection following vaccination.

RESUMO

Allogeneic hematopoietic stem cell transplantation (AHSCT) is a promising strategy for treatment of heavily pretreated mycosis fungoides/Sezary syndrome (MF/SS). Herein, we aimed to evaluate the outcomes of AHSCT for heavily pretreated patients with MF/SS retrospectively. This analysis included consecutive 19 patients with MF/SS who received 20 AHSCT between 2012-2021 in our transplant center. Eight patients have been previously reported. Fifteen patients had diagnosis of MF and referred to SS in five patients. In our cohort, all cases had advanced disease (stages IIB: n = 1, IIIA: n = 7; IIIB: n = 4, IVA: n = 4, and IVB: n = 3). Nine patients (47.4%) had developed large cell transformation. Only two patients received AHSCT in complete response, one very good partial response and two partial response while the others had progressive disease (n = 15) before transplant. Seven (35%) patients were alive at the time of analysis, with a median follow up of 10.5 months (range, 0.3-113 months) after AHSCT. Nine patients (47.4%) died without disease relapse or progression. Non-relapse mortality was 35.9% at 1 year and 26.9% at 3 years and thereafter. For all patients the probability of overall survival was 48.5% and 32.3% at 1- and 5-year post-transplant, respectively. AHSCT for MF/SS resulted in an estimated progression free survival of 45.4% at 1 year. Given the poor prognosis of patients not receiving transplants and in the absence of curative non-transplantation therapies, our results support that AHSCT is able to effectively rescue 32.3% of the population of transplant eligible, heavily pretreated patients in 5 years.

RESUMO

BACKGROUND: The differentiation between the pemphigoid diseases is essential for treatment and prognosis. In Turkey, data on the incidence of these diseases are insufficient. Our aim in this study is to determine the incidence, demographics and clinical characteristics associated with diseases of the pemphigoid group. METHODS: We prospectively analysed 295 patients with pemphigoid who visited dermatology clinics of tertiary referral hospitals in 12 different regions of Turkey within a year. The diagnosis was based on clinical, histopathological, direct immunofluorescence (DIF) and serological (multivariant enzyme-linked immunosorbent assay [ELISA], indirect immunofluorescence and mosaic-based BIOCHIP) examinations. Clinical and demographic findings, aetiological factors and concomitant diseases observed in the patients were recorded. RESULTS: A total of 295 (female/male ratio: 1.7/1) patients with pemphigoid were diagnosed in 1-year period. The overall incidence rate of pemphigoid diseases was found to be 3.55 cases per million-years. The ratio of pemphigoid group diseases to pemphigus group diseases was 1.6. The most common pemphigoid type was bullous pemphigoid (BP, 93.2%). The others were epidermolysis bullosa acquisita (3.1%), pemphigoid gestationis (2.4%), linear IgA disease (1%) and mucous membrane pemphigoid (0.3%). The most common (26.8%) possible trigger of the bullous pemphigoid was gliptin derivative drugs. The most common concomitant diseases with pemphigoid were cardiovascular (27.8%) and neurological diseases (23.7%). CONCLUSIONS: This study showed that the increased frequency of bullous pemphigoid reversed the pemphigoid/pemphigus ratio in Turkey. Further studies are warranted regarding the reasons for this increase.

RESUMO

Folliculotropic mycosis fungoides (FMF) is characterized by a broad clinical spectrum and worse prognosis compared to classical MF. This study aimed to evaluate the clinical characteristics, treatment modalities and long-term outcome and risk factors for progression and survival of FMF patients. We conducted a single-center retrospective study and reviewed 53 patients diagnosed with FMF between 1990 to 2019 in a referral center at Ankara University, Turkey. Regarding to stage at diagnosis, 24 patients (45.3%) had advanced-stage disease (≥IIB). Follicular papules was observed in 66% and alopecia in 49.1% of the cases. Forty-three patients (81.1%) suffered from pruritus. The majority of the patients (92.4%) had at least one systemic therapy. Complete remission was achieved in 24.5% of the patients. The median time of overall survival (OS) was 50 months (range 9-324 months) and 5-year and 10-year OS was 83% and 69%, respectively. Twenty-eight (52.3%) patients progressed to more advanced stages and seven (13.2%) patients died due to MF during the follow-up period. FMF is associated with a progressive course and in most patients, skin-directed therapies were found to be inefficient to control the disease and multiple systemic therapeutic agents were required to control the disease.

RESUMO

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder that causes a significant decline in quality of life. There are numerous treatment options; however, real-life data on the efficacy of these treatments is limited. This study was performed in two centers to describe clinical characteristics and assess treatment outcome in a cohort of 139 patients with HS. Data on demographic and clinical characteristics, Hurley stage and comorbidities were collected from patient charts and evaluated retrospectively. Treatment response was measured with HS clinical response index (HISCR). Mean body mass index was 27.8±4.88. Inflammatory comorbidities were present in 23%. Among first-line drugs systemic doxycycline resulted in 60% HISCR followed by rifampicin-clindamycin combination (46.4%). Isotretinoin had the lowest HISCR (30.7%) in this group. For second-line therapies, all acitretin treated patients achieved response and patients treated with tumor necrosis factor alpha (TNF-α) inhibitors had the highest HISCR. Currently recommended first-line therapies have moderate efficacy in HS. Acitretin appears to be a reasonable alternative for the highly effective TNF-α inhibitors in patients with severe and resistant HS. Overall, these results support that excessive inflammatory response play an important role in pathogenesis of HS.

RESUMO

BACKGROUND: Pathological inflammatory syndromes of unknown etiology are commonly observed in ataxia telangiectasia (AT) and Artemis deficiency. Similar inflammatory manifestations also exist in patients with STING-associated vasculopathy in infancy (SAVI). OBJECTIVE: We sought to test the hypothesis that the inflammation-associated manifestations observed in patients with AT and Artemis deficiency stem from increased type I IFN signature leading to neutrophil-mediated pathological damage. METHODS: Cytokine/protein signatures were determined by ELISA, cytometric bead array, or quantitative PCR. Stat1 phosphorylation levels were determined by flow cytometry. DNA species accumulating in the cytosol of patients' cells were quantified microscopically and flow cytometrically. Propensity of isolated polymorhonuclear granulocytes to form neutrophil extracellular traps (NETs) was determined using fluorescence microscopy and picogreen assay. Neutrophil reactive oxygen species levels and mitochondrial stress were assayed using fluorogenic probes, microscopy, and flow cytometry. RESULTS: Type I and III IFN signatures were elevated in plasma and peripheral blood cells of patients with AT, Artemis deficiency, and SAVI. Chronic IFN production stemmed from the accumulation of DNA in the cytoplasm of AT and Artemis-deficient cells. Neutrophils isolated from patients spontaneously produced NETs and displayed indicators of oxidative and mitochondrial stress, supportive of their NETotic tendencies. A similar phenomenon was also observed in neutrophils from healthy controls exposed to patient plasma samples or exogeneous IFN-α. CONCLUSIONS: Type I IFN-mediated neutrophil activation and NET formation may contribute to inflammatory manifestations observed in patients with AT, Artemis deficiency, and SAVI. Thus, neutrophils represent a promising target to manage inflammatory syndromes in diseases with active type I IFN signature.

RESUMO

H syndrome (OMIM 602782) is a very rare autosomal recessive genodermatosis with multisystem involvement. Hallmarks of this disorder are juvenile onset and progressive, hyperpigmented, hypertrichotic lesions with histiocytic infiltration. Associated systemic manifestations form a long list, and there is high variability between patients. In some patients, dysmorphic and other systemic features may be so subtle that the disorder may readily be mistaken as an acquired skin disease and treated as such. Herein, we report a novel homozygous c.1339G>A (p.Glu447Lys) mutation in the SLC29A3 gene in a patient with skin-dominant presentation of H syndrome. Additionally, due to the present case, double superior vena cava can be added to the list of possible cardiovascular manifestations of H syndrome.

RESUMO

BACKGROUND: Mycosis fungoides (MF) is the most common cutaneous lymphoma with a chronic disease course. MF patients may also suffer from systemic comorbidities such as cardiovascular and metabolic diseases. METHODS: In this study, we aimed to evaluate the demographic and clinical features of MF patients registered in the MF-TR registry system and to examine the relationship of these features with systemic comorbidities. We collected the data from the medical files of the patients via the MF-TR registry system. RESULTS: Our study included 728 patients with MF, of which 396 (54.40%) were male and 332 (45.60%) were female. The most common additional systemic disease observed was hypertension, affecting 124 (17.03%) patients. This was followed by multinodular goiter in 66 (9.06%) patients, and diabetes mellitus type 2 in 61 (8.37%) patients. Twenty-two (3.02%) patients had a history of another secondary malignancy, with lung cancer being the most common type, affecting 5 (0.68%) patients. Female gender and high BMI were statistically higher in MF patients with asthma (P=0.019 and P=0.031, respectively). In patients with hypertension and hypercholesterolemia, the duration of diagnosis was significantly longer (P=0.013 and P=0.047, respectively). CONCLUSIONS: Dermatologists should be aware of these accompanying comorbidities in patients with MF. Multidisciplinary evaluation should be performed in the follow-up, if necessary.

RESUMO

INTRODUCTION: The COVID-19 pandemic drastically changed the priorities in healthcare services; outpatient management of acne has changed during this period. OBJECTIVES: We aimed to investigate treatment practices, outcomes and identify modified follow-up schedules applied during the pandemic. METHODS: The patients who were admitted to dermatology outpatient clinic between March 13 and July 13, 2020, were included. Patients who were admitted between March 13 and July 13, 2019, were served as controls for the study. For each patient, age, gender, treatment protocols, treatment intervals, compliance with the treatment, treatment modifications, and adverse events were recorded. RESULTS: The total number of acne patients admitted to dermatology outpatient clinics during the pandemic period was 278 and consisted of 12.3% (278) of all admissions. Isotretinoin treatment was started in only 16 (5.8%) of the patients. The proportion of patients who were under follow-up was significantly higher during the pandemic period (P < 0.005). There was no difference between the pandemic period and the non-pandemic period in terms of starting isotretinoin treatment (P > 0.05). During pandemic period, 79% of the patients who used isotretinoin were followed-up every two or more months. Extended follow-up intervals showed no difference for detecting side effects (P > 0.05). CONCLUSIONS: Acne patients constitute an important part of dermatology outpatient clinics. During the pandemic period, majority of acne patients came for follow-up. Extended follow-up periods were adopted by physicians and were found safe and effective in the current study. Thus, isotretinoin treatment seems efficacious and safe during pandemic period.

RESUMO

OBJECTIVE: Long-term survival for advanced stages of mycosis fungoides (MF) may be beneficially affected by the use of multimodality therapy. We aim to evaluate the activity of vorinostat in combination with interferon (IFN) alpha and extracorporeal photopheresis (ECP) with persistent, progressive advanced stage MF and Sezary syndrome (SS). PATIENTS AND METHODS: Three patients with stage IIB-IVA MF/SS were treated with vorinostat 400 mg/day/po. Vorinostat was added to ongoing ECP and IFN-alpha-2a therapies in all three patients. RESULTS: The patient with stage IIB MF achieved a complete response. The patient with SS showed a stable disease of less than 50 percent improvement in body surface area with reduction in the sizes of axillary and inguinal lymph nodes. A partial remission was maintained for 24 weeks in the patient with stage IVA MF, followed by rapid disease progression under treatment which led to cessation of vorinostat treatment due to study criteria as well as serious side effects. CONCLUSION: Our experience in this case series is suggestive of the synergistic effect of vorinostat in combination with IFN and ECP and supports the efficacy of vorinostat in inducing prolonged responses in patients with progressive disease and/or stable disease in otherwise progressive and treatment refractory late stage MF/SS.

RESUMO

We describe a patient with cutaneous T-cell lymphoma (CTCL), in association with concurrent ankylosing spondylitis (AS), who achieved a long-lasting complete remission of both diseases after 3 cycles of extracorporeal photochemotherapy (ECP). The combination of CTCL with AS is very rare. In our patient, the CTCL was refractory to psoralen-UVA. He was unable to continue with administration of interferon α because of exacerbation of his back, anterior chest, and bilateral heel pain. The Bath AS Functional Index and Bath AS Disease Activity Index scores were determined to be 2.2 and 5.8, respectively. Extracorporeal photochemotherapy has been shown to be effective in the treatment of CTCL consisting of reinfusion of 3 to 9 × 10 leukocytes, taken from the patient by leukopheresis and treated in an extracorporeal system with 8-methoxypsoralen and UVA. There is a strong suggestion that ECP as a monotherapy can provide a significant benefit for other T-cell-mediated diseases including rheumatoid arthritis and psoriatic arthritis. This is the first report describing an effective treatment of AS in which pain, inflammatory response, Bath AS Disease Activity Index, and Bath AS Functional Index improved after initiation of ECP.

RESUMO

Pemphigus vulgaris (PV) and epidermolysis bullosa acquisita (EBA) sometimes resist treatments. In drug-resistant cases, adjuvant treatment with extracorporeal photochemotherapy (ECP) has been reported to induce remission. However, limited numbers of patients have been reported up to date. Eleven patients with drug-resistant autoimmune bullous diseases have been treated with ECP (8 patients with PV, 3 patients with EBA). The introduction of ECP to systemic therapies of the patients with PV resulted in complete response (CR) after a limited cycle (2-6 cycles) in all, except one patient. Prednisolone doses could be tapered in all patients. ECP resulted in CR in two patients while improvement was partial in one patient with EBA after 3-6 cycles. Our patients demonstrate the efficacy of long-term ECP to be tried in the treatment of aggressive autoimmune bullous disorders. The treatment has produced a remarkable corticosteroid-sparing effect while inducing clinical remission.

RESUMO

There are several reports of patients who developed extracutaneous lymphoma after they started bexarotene treatment. The authors report a case in which the initiation of bexarotene therapy for Sézary syndrome was temporally associated with the development of Hodgkin's lymphoma despite improvement in cutaneous signs and symptoms. It is possible that bexarotene may contribute to the development of extracutaneous lymphoma. Although bexarotene therapy may relieve symptoms and signs of cutaneous T-cell lymphoma, careful examination of the lymph nodes during treatment is recommended.
