Primary cutaneous peripheral T-cell lymphoma, not otherwise specified: results of a multicentre European Organization for Research and Treatment of Cancer (EORTC) cutaneous lymphoma taskforce study on the clinico-pathological and prognostic features.

BACKGROUND: Cutaneous peripheral T-cell lymphoma, not otherwise specified (PTL NOS) is an aggressive, but poorly characterized neoplasm. OBJECTIVES: The European Organization for Research and Treatment of Cancer cutaneous lymphoma taskforce (EORTC CLTF) investigated 33 biopsies of 30 patients with primary cutaneous PTL NOS to analyse their clinical, histological, immunophenotypic features and outcome. METHODS: Retrospective analysis of clinical data and histopathological features by an expert panel. RESULTS: Cutaneous PTL NOS manifested clinically either with solitary or disseminated rapidly grown ulcerated tumours or disseminated papulo-nodular lesions. Histologically, a mostly diffuse or nodular infiltrate in the dermis and often extending into the subcutis was found. Epidermotropism was rarely present and only mild and focal. Unusual phenotypes were frequent, e.g. CD3+ /CD4- /CD8- and CD3+ /CD4+ /CD8+ . Moreover, 18% of the cases exhibited an aberrant expression of the B-cell marker CD20 by the tumour cells. All solitary tumours were located on the limbs and presented a high expression of GATA-3 but this did not correlate with outcome and therefore could not serve as a prognostic factor. The prognosis was shown to be generally poor with 10 of 30 patients (33%) dying of lymphoma within the follow-up of 36 months (mean value; range 3-144). The survival rates were 61% after 3 years (CI, 43-85%) and 54% after 5 years (CI, 36-81%). Small to medium-sized morphology of tumour cells was associated with a better outcome than medium to large or large tumour cells. Age, gender, clinical stage, CD4/CD8 phenotype and GATA-3 expression were not associated with prognosis. Chemotherapy was the most common treatment modality, but surgical excision and/or radiotherapy may represent an appropriate first-line treatment for solitary lesions. CONCLUSIONS: Cutaneous PTL NOS shows an aggressive course in most patients independent of initial presentation, age and phenotype. Cytomorphology was identified as a prognostic factor. The data indicate a need for more effective treatment modalities in PTL NOS.

Should we be imaging lymph nodes at initial diagnosis of early-stage mycosis fungoides? Results from the PROspective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) international study.

BACKGROUND: Early-stage mycosis fungoides (MF) includes involvement of dermatopathic lymph nodes (LNs) or early lymphomatous LNs. There is a lack of unanimity among current guidelines regarding the indications for initial staging imaging in early-stage presentation of MF in the absence of enlarged palpable LNs. OBJECTIVES: To investigate how often imaging is performed in patients with early-stage presentation of MF, to assess the yield of LN imaging, and to determine what disease characteristics promoted imaging. METHODS: A review of clinicopathologically confirmed newly diagnosed patients with cutaneous patch/plaque (T1/T2) MF from PROspective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) data. RESULTS: PROCLIPI enrolled 375 patients with stage T1/T2 MF: 304 with classical MF and 71 with folliculotropic MF. Imaging was performed in 169 patients (45%): 83 with computed tomography, 18 with positron emission tomography-computed tomography and 68 with ultrasound. Only nine of these (5%) had palpable enlarged (≥ 15 mm) LNs, with an over-representation of plaques, irrespectively of the 10% body surface area cutoff that distinguishes T1 from T2. Folliculotropic MF was not more frequently imaged than classical MF. Radiologically enlarged LNs (≥ 15 mm) were detected in 30 patients (18%); only seven had clinical lymphadenopathy. On multivariate analysis, plaque presentation was the sole parameter significantly associated with radiologically enlarged LNs. Imaging of only clinically enlarged LNs upstaged 4% of patients (seven of 169) to at least IIA, whereas nonselective imaging upstaged another 14% (24 of 169). LN biopsy, performed in eight of 30 patients, identified N3 (extensive lymphomatous involvement) in two and N1 (dermatopathic changes) in six. CONCLUSIONS: Physical examination was a poor determinant of LN enlargement or involvement. Presence of plaques was associated with a significant increase in identification of enlarged or involved LNs in patients with early-stage presentation of MF, which may be important when deciding who to image. Imaging increases the detection rate of stage IIA MF, and identifies rare cases of extensive lymphomatous nodes, upstaging them to advanced-stage IVA2.

Characteristics associated with significantly worse quality of life in mycosis fungoides/Sézary syndrome from the Prospective Cutaneous Lymphoma International Prognostic Index (PROCLIPI) study.

BACKGROUND: Mycosis fungoides (MF) and Sézary Syndrome (SS) are the most common cutaneous T-cell lymphomas. MF/SS is accompanied by considerable morbidity from pain, itching and disfigurement. AIM: To identify factors associated with poorer health-related quality of life (HRQoL) in patients newly diagnosed with MF/SS. METHODS: Patients enrolled into Prospective Cutaneous Lymphoma International Prognostic Index (PROCLIPI; an international observational study in MF/SS) had their HRQoL assessed using the Skindex-29 questionnaire. Skindex-29 scores were analysed in relation to patient- and disease-specific characteristics. RESULTS: The study population consisted of 237 patients [60·3% male; median age 60 years, (interquartile range 49-70)], of whom 179 had early MF and 58 had advanced MF/SS. In univariate analysis, HRQoL, as measured by Skindex-29, was worse in women, SS, late-stage MF, those with elevated lactate dehydrogenase, alopecia, high modified Severity Weighted Assessment Tool and confluent erythema. Linear regression models only identified female gender (ß = 8·61; P = 0·003) and alopecia (ß = 9·71, P = 0·02) as independent predictors of worse global HRQoL. Item-level analysis showed that the severe impairment in symptoms [odds ratio (OR) 2·14, 95% confidence interval (CI) 1·19-3·89] and emotions (OR 1·88, 95% CI 1·09-3·27) subscale scores seen in women was caused by more burning/stinging, pruritus, irritation and greater feelings of depression, shame, embarrassment and annoyance with their diagnosis of MF/SS. CONCLUSIONS: HRQoL is significantly more impaired in newly diagnosed women with MF/SS and in those with alopecia. As Skindex-29 does not include existential questions on cancer, which may cause additional worry and distress, a comprehensive validated cutaneous T-cell lymphoma-specific questionnaire is urgently needed to more accurately assess disease-specific HRQoL in these patients. What's already known about this topic? Cross-sectional studies of mixed populations of known and newly diagnosed patients with mycosis fungoides (MF)/Sézary syndrome (SS) have shown significant impairment in health-related quality of life (HRQoL). Previous studies on assessing gender-specific differences in HRQoL in MF/SS are conflicting. More advanced-stage disease and pruritus is associated with poorer HRQoL in patients with MF/SS. What does this study add? This is the first prospective study to investigate HRQoL in a homogenous group of newly diagnosed patients with MF/SS. In patients newly diagnosed with MF/SS, HRQoL is worse in women and in those with alopecia and confluent erythema. MF/SS diagnosis has a multidimensional impact on patient HRQoL, including a large burden of cutaneous symptoms, as well as a negative impact on emotional well-being.

The PROCLIPI international registry of early-stage mycosis fungoides identifies substantial diagnostic delay in most patients.

BACKGROUND: Survival in mycosis fungoides (MF) is varied and may be poor. The PROCLIPI (PROspective Cutaneous Lymphoma International Prognostic Index) study is a web-based data collection system for early-stage MF with legal data-sharing agreements permitting international collaboration in a rare cancer with complex pathology. Clinicopathological data must be 100% complete and in-built intelligence in the database system ensures accurate staging. OBJECTIVES: To develop a prognostic index for MF. METHODS: Predefined datasets for clinical, haematological, radiological, immunohistochemical, genotypic, treatment and quality of life are collected at first diagnosis of MF and annually to test against survival. Biobanked tissue samples are recorded within a Federated Biobank for translational studies. RESULTS: In total, 430 patients were enrolled from 29 centres in 15 countries spanning five continents. Altogether, 348 were confirmed as having early-stage MF at central review. The majority had classical MF (81·6%) with a CD4 phenotype (88·2%). Folliculotropic MF was diagnosed in 17·8%. Most presented with stage I (IA: 49·4%; IB: 42·8%), but 7·8% presented with enlarged lymph nodes (stage IIA). A diagnostic delay between first symptom development and initial diagnosis was frequent [85·6%; median delay 36 months (interquartile range 12-90)]. This highlights the difficulties in accurate diagnosis, which includes lack of a singular diagnostic test for MF. CONCLUSIONS: This confirmed early-stage MF cohort is being followed-up to identify prognostic factors, which may allow better management and improve survival by identifying patients at risk of disease progression. This study design is a useful model for collaboration in other rare diseases, especially where pathological diagnosis can be complex.

Folliculotropic mycosis fungoides: clinicopathological analysis of 17 patients.

BACKGROUND: Folliculotropic mycosis fungoides (FMF) represents a variant of MF characterized by hair follicle invasion of mature, CD4-positive small lymphoid cells with cerebriform nuclei. The disease displays resistance to standard treatment modalities and has an unfavourable course. OBJECTIVE: Clinical analysis of 17 patients with FMF collected between 2005 and 2012, investigation of tumour cells and involved hair follicle. METHODS: Re-evaluation of clinical data, wide panel immunohistochemistry investigation on paraffin-embedded biopsy material, T-cell receptor gene rearrangement analysis of the samples. RESULTS: Male and older age group predominance, frequent head-neck involvement, acneiform lesions, keratotic plugs, cysts, nodules, follicular papules, alopecia and classic mycosis fungoides-like plaques represented the main clinical characteristics. Treatment response showed a wide range from transient complete response to therapy resistance and death due to the disease. The pathological alterations: folliculotropism, mild epidermotropism, follicular plugging, mucinous degeneration of hair follicle, basaloid hyperplasia, syringotropism were similar to those observed previously. The first case of a CD8-positive folliculotropic mycosis fungoides - with unusual clinical presentation - is reported here. Nestin overexpression of mesenchymal cells of the isthmic and suprabulbar regions of hair follicle and the reappearance of dermal nestin-expressing cells were observed in association with immature dendritic cell hyperplasia. Altered CK19 expression was detected suggesting a potential role of follicular keratinocytes in the disease process. It was found that a proportion of neoplastic T cells constantly express programmed death-1 receptor in our patients contrary to classic mycosis fungoides. CONCLUSION: The spectrum of the clinical manifestation and the course of folliculotropic mycosis fungoides are broad and differ from classic mycosis fungoides. Folliculotropic neoplastic T-cell proliferation is associated with activation of inflammatory reactive T- and B-lymphoid cells, mesenchymal cells and changes in the hair follicle.

Incidence and antibiotic susceptibility of genital mycoplasmas in sexually active individuals in Hungary.

The aim of this study was to examine the incidence and antibiotic sensitivity of Ureaplasma urealyticum and Mycoplasma hominis strains cultured from the genital discharges of sexually active individuals who attended our STD outpatient service. Samples were taken with universal swab (Biolab®, Budapest, Hungary) into the Urea-Myco DUO kit (Bio-Rad®, Budapest, Hungary) and incubated in ambient air for 48 h at 37 °C. The determination of antibiotic sensitivity was performed in U9 and arginin broth using the SIR Mycoplasma kit (Bio-Rad®, Budapest, Hungary) under the same conditions. Between 01.05.2008 and 31.12.2011, 373/4,466 (8.35 %) genito-urethral samples with U. urealyticum and 41/4,466 (0.91 %) genito-urethral samples with M. hominis infection were diagnosed in sexually active individuals in the National STD Center, Semmelweis University. U. urealyticum was isolated in 12.54 % in the cervix and 4.1 % in the male urethra, while M. hominis was isolated in 1.33 % in the cervix and 0.51 % in the male urethra. The affected age group was between 21 and 60 years old. U. urealyticum strains were sensitive to tetracycline (95.9 %), doxycycline (97.32 %), and azithromycin (85.79 %), and resistant to erythromycin (81.23 %), clindamycin (75.06 %), and ofloxacin (25.2 %). Cross-resistance occurred in 38.71 % of patients to erythromycin and clindamycin. M. hominis strains were sensitive to clindamycin, ofloxacin, and doxycycline in more than 95 %, to tetracycline in 82.92 %, and no cross-resistance was detected among the antibiotics. Our study confirms that the continuously changing antibiotic resistance of ureaplasmas and mycoplasmas should be followed at least in a few centers in every country, so as to determine the best local therapy options for sexually transmitted infection (STI) patients.

No significant change of plasma beta-endorphin levels of psoriasis patients after synchronous balneophototherapy.

BACKGROUND/PURPOSE: Previous studies suggested that beta-endorphin has a pathogenic role in psoriasis: its increased plasma concentration may play a role in the neuroimmunological processes in the pathomechanism of the disease, and plasma beta-endorphin levels should reflect the changes in the patients' skin status. The purpose of this study was to investigate the changes of peripheral blood beta-endorphin levels in psoriatic patients in conjunction with changes in their skin symptoms after synchronous balneophototherapy. METHODS: With synchronous balneophototherapy, 12 patients with extended skin symptoms of psoriasis were treated. The therapy followed the Regensburg protocol, consisting of a basic course of 35 sessions. Patients' skin status was characterized by evaluating the Psoriasis Area and Severity Index score before and after the therapy course. Blood samples were taken before treatment, and 1 day after the last session, with symptom-free skin. Plasma beta-endorphin levels were measured by a specific radioimmunoassay developed by the authors. RESULTS: There was no significant change in plasma levels of beta-endorphin after clinical clearance of psoriatic skin symptoms. CONCLUSION: In this non-randomized, uncontrolled study no significant difference could be detected between plasma beta-endorphin levels before and after a basic course of synchronous balneophototherapy in patients with psoriasis. Although beta-endorphin has many neuroimmunological effects, the changes of its plasma level do not consistently reflect the skin status. Inflammation in psoriatic skin lesions is probably not mediated directly by circulating beta-endorphin.

The effect of heat-inactivated Helicobacter pylori on the blastogenic response of peripheral blood mononuclear cells of patients with chronic urticaria.

BACKGROUND: Helicobacter pylori, the most important etiologic factor of gastritis and peptic ulcer, has recently been associated with several extradigestive diseases. Previous studies reported conflicting results on H. pylori eradication in chronic urticaria, in that some studies showed a benefit, while others found no effect. METHODS: Peripheral blood mononuclear cells of 24 chronic urticaria patients (13 seropositive/11 seronegative for H. pylori) and 18 healthy controls (9 seropositive/9 seronegative) were stimulated with whole heat-inactivated H. pylori (8 x 10(5), 8 x 10(6 )and 8 x 10(7) bacteria/well), phytohemagglutinin (2 microg/ml) and pokeweed mitogen (5 microg/ml). The proliferative response was determined by (3)H-thymidine incorporation. Helicobacter-specific IgG antibody response was determined by ELISA. RESULTS: There were significantly higher proliferative responses to various concentrations of whole heat-inactivated H. pylori antigen in 6- to 7-day cultures of peripheral blood mononuclear cells of chronic urticaria patients compared to healthy controls. We found a tendency to exhibit a higher proliferative response to either Helicobacter antigens or mitogens in seropositive compared to seronegative patients. CONCLUSION: Our results support the hypothesis that there is an increased lymphocyte reactivity in chronic urticaria, perhaps further enhanced by the presence of H. pylori which, therefore, may be involved as a trigger in the pathogenesis of chronic urticaria.

[Interferon-alpha and PUVA therapy for mycosis fungoides]. / Mycosis fungoides interferon-alfa- és PUVA-kezelése.

14 patients suffering from early stage mycosis fungoides were treated with interferon alpha 2-a and PUVA/1 patient in stage I a, 3 patients in stage I b, 4 patients in stage II a and 6 patients in stage II b/during 3-21 months time course. Interferon alpha 2-a was administered 3 times a week, in escalating dose from 3 MU to 9 MU, determining the individual maximal tolerated dose. All of the patients responded well to the treatment. Partial remission was observed after 4-13 weeks of treatment. Total remission developed in 8 cases, after 8 weeks- 9 months of the treatment. Side effects occurred frequently: weight loss, pain, fever, fatigue, leucopenia, thrombopenia, liver enzyme elevation. Because of the side effects the dose of the interferon was reduced individually, the dose reduction did not cause relapse.

[Diagnosis of cutaneous lymphomas]. / Cutan lymphomák diagnosztikája.

Diagnosis of cutaneous lymphoma is based on the clinical picture and the histology. Several, different clinical entities are the members of this group with various clinical and histological features, with different course and prognosis. The clinical picture resembles that of a wide variety of benign, inflammatory dermatosis. The histological characteristics in the early lesions are not pathognomic, therefore immunohistochemistry and gene rearrangement studies are necessary to establish the diagnosis. These processes are evaluated in the article.

Measurement of intracellular interferon-gamma and interleukin-4 in whole blood T lymphocytes from patients with systemic lupus erythematosus.

Contradictory data are available about the dominance of T-helper 1 (T(H)1), or T-helper 2 (T(H)2) cytokines in systemic lupus erythematosus (SLE). Therefore, intracellular interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) production of T lymphocytes was measured in whole blood of healthy donors and active and inactive SLE patients by flow cytometry. The percentage of IFN-gamma and IL-4 positive cells was low (<1%) in unstimulated samples of the healthy controls, while that of IFN-gamma and IL-4 positive cells in the stimulated cells was 25.2+/-10.6% and 0.6+/-1.5%, respectively. No significant difference was found between SLE patients and healthy controls and between active and inactive patients in these parameters either in the unstimulated or in the stimulated samples. One patient with severe disease had as high as 11.8% IL-4 positive cells and 12.5% IFN-gamma positive cells in the stimulated samples, but after the initiation of intensive corticosteroid and cytostatic therapy, the percentage of IL-4 positive T cells decreased (4.76%) while that of IFN-gamma positive T cells increased (47.91%). We conclude that the intracellular IL-4 and IFN-gamma expression of T lymphocytes does not differ markedly between SLE patients and healthy controls, with the possible exception of severe disease, when marked IL-4 overproduction may exist beside low IFN-gamma production. Furthermore, corticosteroid and cytostatic therapy might normalize this altered IFN-gamma/IL-4 ratio.

[Dermatomyositis: clinical study of 34 patients]. / Dermatomyositis: klinikai megfigyelések 34 betegen.

Clinical data of 34 patients with DM, who have been treated during the years 1971 and 1998 were evaluated. 79% of the patients (27 patients) were female, 21% of them (7 patients) were male. 59% of the patients (20 pts) were between the ages of 41 and 50 years. The characteristic heliotrop rash were observed in 26 patients, Gottron's papules in 20 patients, poikiloderma in 2 patients, calcification, ulcers, Raynaud syndrome in 1 patient. 3 of the 34 patients presented with strongly itching erythematopapulosus symptoms, most prominently on the scalp. Cardiac involvement were present in 10 patients (29%), lung involvement in 8 patients (23%), gastrointestinal complaints in 11 patients, dysphagia, dysphonia in 4 patients, joint pain in 5 patients. Overlap syndrome--scleroderma-dermatomyositis, SLE-dermatomyositis--was present in 2 patients. 9 of the 34 patients (26%) suffered from malignant tumours: gastric, breast, lung, epipharynx carcinoma, malignant melanoma. 13 of the 34 patients have been treated with corticosteroids together with immunosuppressor agents, in most cases azathioprin was administered. Cyclosporin was given in 7 cases, chloroquine in 2 cases.

[Ito hypomelanosis (incontinentia pigmenti achromians)]. / Hypomelanosis Ito (incontinentia pigmenti achromians).

Authors report the case of a white male patient suffering from a rare neurocutaneous dysplasia. Macrocrania and right ventricular dilation of the brain were present at birth. Motor milestones were delayed and epilepsy with staring spells started at the age of 6 months. On examination at 2 years of age hypopigmented areas of linear distribution were noted on the right extremities and on the right side of the trunk, beyond macrocrania, psychomotor and mental delay. Cranial MRI performed at 5 years of age proved predominantly right-sided megalencephaly, gray matter heterotopia within the right hemispherium and polymicrogyria in the perisylvian region. The EEG was characterized by high-amplitude rhythmic theta activity over the right frontal area. Hypomelanosis of Ito was diagnosed. Authors call attention on the importance of skin lesions in neuropediatric disorders, and give a brief review of the literature in hypomelanosis of Ito.
