Glucose metrics and device satisfaction in adults with type 1 diabetes using different treatment modalities: a multicenter, real-world observational study.

AIMS: To evaluate glucose metrics, device satisfaction and diabetes impact in adults with type 1 diabetes using different treatment modalities in a real-life setting in Italy. METHODS: This was a multicentre, nationwide, cross-sectional study. Candidates were consecutively evaluated for eligibility during their routine medical visit at the diabetes centre. Researchers collected comprehensive demographic, socioeconomic, anamnestic and clinical data, and administered the Diabetes Impact and Device Satisfaction scale. RESULTS: From 2021 to 2022, a total of 428 subjects, 45% males, with a median age of 32 years (IQR 23-47) were recruited in 11 participating centres from all over Italy. No differences in age, physical activity, and diabetes impact were found for the different treatment modalities. HCL/AHCL and SAP groups reported higher device satisfaction vs. MDI + SMBG and MDI + CGM (p < 0.001). Subjects treated with HCL/AHCL exhibited significantly higher TIR and significantly lower time spent in hypoglycemia level 1, time spent in hyperglycemia, CV and GMI compared to MDI + CGM, and significantly higher TIR and significantly lower time spent in hypoglycemia level 2, time spent in hyperglycemia, and CV compared to SAP. Significant reduction in hypoglycemia level 2 was also found with PLGM compared to SAP. High education attainment was associated with optimal metabolic control. CONCLUSION: Real-life use of advanced technologies for type 1 diabetes is associated with improved glucose metrics and device satisfaction. Education level also contributes to success of treatment.

Gender differences in adult atopic dermatitis and clinical implication: Results from a nationwide multicentre study.

BACKGROUND: Atopic dermatitis (AD) is a common inflammatory skin disease that affects both children and adults. However, limited research has been conducted on gender differences in AD. OBJECTIVES: This study aimed to assess gender differences in adult AD patients, focusing on demographic and clinical features, comorbidities and treatment approaches. METHODS: In this multicentre, observational, cross-sectional study, we enrolled 686 adult patients with AD (357 males and 329 females). For each patient, we collected demographic data (age and sex), anthropometric measurements (weight, height, hip circumference, waist circumference and waist-to-hip ratio), clinical information (onset age, disease duration, severity, itching intensity, impact on quality of life) and noted comorbidities (metabolic, atopic and other). We recorded past and current topical and systemic treatments. We analysed all collected data using statistical techniques appropriate for both quantitative and qualitative variables. Multiple correspondence analysis (MCA) was employed to evaluate the relationships among all clinical characteristics of the patients. RESULTS: We found no differences in age at onset, disease duration, severity and quality of life impact between males and females. Males exhibited higher rates of hypertriglyceridaemia and hypertension. No significant gender differences were observed in atopic or other comorbidities. Treatment approaches were overlapping, except for greater methotrexate use in males. MCA revealed distinct patterns based on gender, disease severity, age of onset, treatment and quality of life. Adult males with AD had severe disease, extensive treatments and poorer quality of life, while adult females had milder disease, fewer treatments and moderate quality of life impact. CONCLUSIONS: Our study reveals that gender differences in adult AD patients are largely due to inherent population variations rather than disease-related disparities. However, it highlights potential undertreatment of females with moderate AD and quality of life impact, emphasizing the need for equitable AD treatment. JAK inhibitors may offer a solution for gender-based therapeutic parity.

Validity of age estimation methods and reproducibility of bone/dental maturity indices for chronological age estimation: a systematic review and meta-analysis of validation studies.

Several approaches have been developed to estimate age, an important aspect of forensics and orthodontics, using different measures and radiological examinations. Here, through meta-analysis, we determined the validity of age estimation methods and reproducibility of bone/dental maturity indices used for age estimation. The PubMed and Google Scholar databases were searched to December 31, 2021 for human cross-sectional studies meeting pre-defined PICOS criteria that simultaneously assessed the reproducibility and validity. Meta-estimates of validity (mean error: estimated age-chronological age) and intra- and inter-observer reproducibility (Cohen's kappa, intraclass correlation coefficient) and their predictive intervals (PI) were calculated using mixed-effect models when heterogeneity was high (I2 > 50%). The literature search identified 433 studies, and 23 met the inclusion criteria. The mean error meta-estimate (mixed effects model) was 0.08 years (95% CI - 0.12; 0.29) in males and 0.09 (95% CI - 0.12; 0.30) in females. The PI of each method spanned zero; of nine reported estimation methods, Cameriere's had the smallest (- 0.82; 0.47) and Haavikko's the largest (- 7.24; 4.57) PI. The reproducibility meta-estimate (fixed effects model) was 0.98 (95% CI 0.97; 1.00) for intra- and 0.99 (95% CI 0.98; 1.00) for inter-observer agreement. All methods were valid but with different levels of precision. The intra- and inter-observer reproducibility was high and homogeneous across studies.

Comorbidities and treatment patterns in adult patients with atopic dermatitis: results from a nationwide multicenter study.

Adult atopic dermatitis (adult AD) is a systemic inflammatory disorder, whose relationship with immune-allergic and metabolic comorbidities is not well established yet. Moreover, treatment of mild-to-moderate and severe atopic dermatitis needs standardization among clinicians. The aim of this study was to evaluate the distribution of comorbidities, including metabolic abnormalities, rhinitis, conjunctivitis, asthma, alopecia and sleep disturbance, according to severity of adult AD, and describe treatments most commonly used by Italian dermatologists. Retrospective, observational, nationwide study of adult patients over a 2-year period was performed. Clinical and laboratory data were obtained through review of medical records of patients aged ≥ 18 years, followed in 23 Italian National reference centres for atopic dermatitis between September 2016 and September 2018. The main measurements evaluated were disease severity, atopic and metabolic comorbidities, treatment type and duration. Six-hundred and eighty-four adult patients with AD were included into the study. Atopic, but not metabolic conditions, except for hypertension, were significantly associated with having moderate-to-severe AD in young adult patients. Disease duration was significantly associated with disease severity. Oral corticosteroids and cyclosporine were the most widely used immunosuppressant. Our study seems confirm the close relationship between adult AD and other atopic conditions, further long-term cohort studies on patients affected by adult AD need to be performed to evaluate the complex relationship between adult AD disease severity and metabolic comorbidities.

A 6-month follow-up study of the randomized controlled Ma-Pi macrobiotic dietary intervention (MADIAB trial) in type 2 diabetes.

BACKGROUND: In the MADIAB trial (a 21-day randomized, controlled trial in patients with type 2 diabetes (T2D)), intervention with the Ma-Pi 2 macrobiotic diet resulted in significantly greater improvements in metabolic control compared with a standard recommended diet for patients with T2D. We report on a 6-month follow-up study, which investigated, whether these benefits extended beyond the 21-day intensive dietary intervention, in real-world conditions. SUBJECTS: At the end of the MADIAB trial (baseline of this follow-up study), all participants continued their assigned diet (Ma-Pi or control) for 6 months. The Ma-Pi 2 group followed the Ma-Pi 4 diet during this follow-up study. Forty of the original 51 subjects (78.4%) participated in the follow-up (body mass index, 27-45 kg m(-2); age, 40-75 years). Primary outcome was percentage change from baseline in HbA1c; secondary outcomes were anthropometric data and lipid panel. RESULTS: A significantly greater median percentage reduction was observed for HbA1c in the Ma-Pi group (-11.27% (95% confidence interval (CI): -10.17; -12.36)) compared with the control group (-5.88% (95% CI: -3.79; -7.98)) (P < 0.001). Total and low-density lipoprotein (LDL) cholesterol increased in both groups with no differences between groups (P=0.331 and P=0.082, respectively). After correcting for age and gender, the Ma-Pi diet was associated with a higher percentage reduction in HbA1c (95% CI: 2.56; 7.61) and body weight (95% CI: 0.40; 3.99), and a higher percentage increase in LDL cholesterol (95% CI: -1.52; -33.16). However, all participants' total and LDL cholesterol levels remained within recommended ranges (<200 mg dl(-1) and <100 mg dl(-1), respectively). The Ma-Pi diet group achieved the target median HbA1c value (<5.7% (39 mmol mol(-1))) at 6 months. CONCLUSIONS: Both the Ma-Pi and control diets maintained their benefits beyond the 21-day intensive monitored intervention over a 6-month follow-up in real-world conditions. The Ma-Pi diet resulted in greater improvement in glycemic control.

Real-time sonoelastography as novel follow-up method in Achilles tendon surgery.

PURPOSE: To evaluate the sonoelastographic features of Achilles tendon healing after percutaneous treatment using real-time sonoelastography, a new tool able to quantify deformation in biological tissues. METHODS: Patients with atraumatic Achilles tendon ruptures, treated with a percutaneous technique, were assessed. Sonoelastographic evaluations were performed at the myotendinous junction, tendon body/lesion site and osteotendinous junction, both for the operated and contralateral side, at 40 days, 6 months and 1 year after surgery. Using standard regions of interest, the "strain index" (SI) was calculated as an indicator of tendon elasticity. Clinical outcomes were assessed by the ATRS questionnaire at 6 months and 1 year post-operatively and correlated with sonoelastographic findings. Sixty healthy tendons from 30 volunteers were used to provide a healthy control range. RESULTS: Twenty-five patients were recruited for this study. The SI in treated tendons showed progressive stiffening over time, especially at myotendinous junction and at the site of the sutured lesion, resulting in significantly higher stiffness than both the contralateral tendon and healthy volunteers. Peak thickness of treated tendons occurred at 6 months, with a tendency to reduce at 1 year, while never achieving a normal physiological state. Greatest remodelling was seen at the lesion site. The contralateral tendon showed significant thickening at the myotendinous and osteotendinous junctions. The SI of the contralateral tendon was found to be stiffer than physiological values found in the control group. ATRS score improved significantly between 6 months and 1 year, being negatively correlated with the SI (p < 0.001). CONCLUSION: RTSE showed that operatively treated Achilles tendons become progressively stiffer during follow-up, while the ATRS score improved. From a biomechanical point of view, at 1 year after surgery Achilles tendons did not show a "restitutio ad integrum". Real-time sonoelastography provides more qualitative and quantitative details in the diagnostics and follow-up of Achilles tendon conditions as the post-operative evolution of the repairing tissue. LEVEL OF EVIDENCE: Diagnostic and therapeutic study, Level III.

Epidemiology and clinical outcome of Healthcare-Associated Infections: a 4-year experience of an Italian ICU.

BACKGROUND: Due to their impact on the outcome, hospital-acquired infections (HAIs) in ICUs represent a critical issue of patients' assistance. This study describes microbiological and clinical findings of a surveillance program covering 4 years in an Italian ICU. METHODS: Patients staying for >48 hours were prospectively followed until discharge or death. For each patient, infections after admissions, duration of device exposure and causal pathogens were noted. A multivariable logistic regression analysis concerning ICU mortality was made. RESULTS: Incidence density rates were 23.14 VAPs, 6.6 CLABSIs and 5.45 CAUTIs (per 1000 device-days) with an increase in yearly rates during the study period (P<0.001). Use of invasive devices was significantly longer among infected patients (P<0.001, for each), whose proportion was higher among medical admissions (P=0.009). The most frequent source of infection was the lung (78%), followed by bloodstream (23%). MSSA was the most frequently isolated pathogen (26%) but Gram-negatives were found in 86.1% of infected patients, with a high degree of resistance to carbapenems (27.5% for Klebsiella pneumoniae). APACHE score, immunosuppression, duration of mechanical ventilation, surgical admission and abdominal infections were independent predictors of ICU mortality (P<0.001; P<0.001; P=0.006; P=0.027; P=0.006, respectively). CONCLUSION: Our infection rates are higher than those reported by other studies. The use of devices and a medical admission share a significant relationship with infection presence. A greater degree of organ failure and the development of an abdominal sepsis are risk factors for mortality.

Epidemiology and outcome of systemic infections due to saprochaete capitata: case report and review of the literature.

A case of systemic infection due to Saprochaete capitata in a patient with chronic lymphocytic leukemia is described. A review of the literature was conducted to identify all reported cases of this infection described between 1977 and August 2013. One hundred and four cases (included the present one) were identified. The median age of the patients was 56 years and 56% were males. Comorbidities included acute myeloid leukemia (52%), acute lymphoid leukemia (22%), other hematological malignancies (13%) and non-hematological diseases (9%). At the time of the infection, 82% of the patients were neutropenic. In 75% of the cases, the yeast was isolated from blood culture, in 25% from other sterile sites. Empirical treatment was done in 36% of the cases. Fifty-eight percent of the individual cases were treated with a combination or a sequential antifungal therapy. Amphotericin B was the antifungal drug most commonly used, followed by voriconazole and itraconazole. The overall crude mortality was 60%. Saprochaete capitata causes life-threatening infections in neutropenic patients. This comprehensive literature review may help the clinician to optimize the management of this rare infection.

Glycaemic control of Type 1 diabetes in clinical practice early in the 21st century: an international comparison.

AIMS: Improving glycaemic control in people with Type 1 diabetes is known to reduce complications. Our aim was to compare glycaemic control among people with Type 1 diabetes using data gathered in regional or national registries. METHODS: Data were obtained for children and/or adults with Type 1 diabetes from the following countries (or regions): Western Australia, Austria, Denmark, England, Champagne-Ardenne (France), Germany, Epirus, Thessaly and Thessaloniki (Greece), Galway (Ireland), several Italian regions, Latvia, Rotterdam (The Netherlands), Otago (New Zealand), Norway, Northern Ireland, Scotland, Sweden, Volyn (Ukraine), USA and Wales) from population or clinic-based registries. The sample size with available data varied from 355 to 173 880. Proportions with HbA1c < 58 mmol/mol (< 7.5%) and ≥ 75 mmol/mol (≥ 9.0%) were compared by age and sex. RESULTS: Data were available for 324 501 people. The proportions with HbA1c 58 mmol/mol (< 7.5%) varied from 15.7% to 46.4% among 44 058 people aged < 15 years, from 8.9% to 49.5% among 50 766 people aged 15-24 years and from 20.5% to 53.6% among 229 677 people aged ≥ 25 years. Sex differences in glycaemic control were small. Proportions of people using insulin pumps varied between the 12 sources with data available. CONCLUSION: These results suggest that there are substantial variations in glycaemic control among people with Type 1 diabetes between the data sources and that there is room for improvement in all populations, especially in young adults.

IL-1ß and TGF-ß weaken the placental barrier through destruction of tight junctions: an in vivo and in vitro study.

INTRODUCTION: Chorioamnionitis is a gestational pathological condition characterized by acute inflammation of the amniochorionic membranes and placentas leading to high concentrations of IL-1ß, Il-6, Il-8 and TGF-ß in the amniotic fluid. In normal conditions, the permeability of foeto-maternal barrier is due to the assembly and maintenance of different cellular junctional domains. METHODS: In the present study, first we aimed to evaluate the protein expression (by immunohistochemistry and western blotting) and mRNA (by real time PCR) levels of the molecular components of tight junctions (Zonula occludens-1 and occludin), and of adherent junctions (VE-cadherin and ß-catenin) in placentas from chorioamnionitis compared to that in normal pregnancies. RESULTS: Western blotting results showed a significant down-regulation of occludin in placentas affected with chorioamnionitis. No differences were detected for the other proteins analysed. We evaluated whether occludin expression was regulated by IL-1ß, IL-6, IL-8 and TGF-ß by means of in vitro studies using HUVEC cultures and demonstrated a key role of IL-1ß and TGF-ß in the disappearance of occludin at cellular border. CONCLUSIONS: We conclude by suggesting a pivotal role of these two cytokines in facilitating intra-placental infection via para-cellular way due to the disassembly of tight junctions at trophoblastic and endothelial cells in placental tissues.

Periodontal status in the Down's syndrome subjects living in central-eastern Italy: the effects of place of living.

AIM: The purpose of this study was to determine the influence of the place of living on periodontal status of 62 Down's syndrome (DS) subjects resident at home (DSH) or in specialized institutes (DSI) in central-eastern Italy. METHODS: The demographic characteristics of the subjects and the periodontal variables were evaluated according to their living conditions. Descriptive analyses were conducted by stratifying subjects into three age groups (0-13; 14-22; >23 years), using medians and 25th-75th percentiles to summarized data. Comparisons between DSH and DSI subjects were performed using Wilcoxon rank sum test. The effect of demographic and clinical variables on periodontal status was evaluated by means of quantile regression analysis. RESULTS: No significant differences resulted between DSH and DSI patients, when compared for gender, age and mental retardation. No significant differences were found in the periodontal variables for the subjects with 0-13 years, while DSI subjects between 14 and 22 years of age presented higher levels of plaque index, probing depth, clinical attachment loss and a lower number of surviving teeth compared to DSH subjects. When DSI and DSH groups ≥ 23 years of age were compared, no differences were observed in the periodontal conditions except for PI and the number of surviving teeth. Age, body mass index and severe mental retardation were found to be significant predictors of periodontal conditions. CONCLUSIONS: Institutionalization has a negative effect on surviving teeth number of Down's syndrome subjects. Furthermore, the home care seems to produce benefits on the periodontal conditions of DSH 14-22 years of age.

Osteomyelitis caused by Aspergillus species: a review of 310 reported cases.

Aspergillus osteomyelitis is a rare infection. We reviewed 310 individual cases reported in the literature from 1936 to 2013. The median age of patients was 43 years (range, 0-86 years), and 59% were males. Comorbidities associated with this infection included chronic granulomatous disease (19%), haematological malignancies (11%), transplantation (11%), diabetes (6%), pulmonary disease (4%), steroid therapy (4%), and human immunodeficiency virus infection (4%). Sites of infection included the spine (49%), base of the skull, paranasal sinuses and jaw (18%), ribs (9%), long bones (9%), sternum (5%), and chest wall (4%). The most common infecting species were Aspergillus fumigatus (55%), Aspergillus flavus (12%), and Aspergillus nidulans (7%). Sixty-two per cent of the individual cases were treated with a combination of an antifungal regimen and surgery. Amphotericin B was the antifungal drug most commonly used, followed by itraconazole and voriconazole. Several combination or sequential therapies were also used experimentally. The overall crude mortality rate was 25%.

Health-related quality of life and treatment preferences in adolescents with type 1 diabetes. The VIPKIDS study.

A multi-centre, observational, cross-sectional study was carried out to determine whether the health-related quality of life (HRQOL) of adolescents with type 1 diabetes is affected by different insulin treatment systems, and which features of HRQOL are impacted by the respective insulin treatment. The study regarded 577 adolescents, aged 10-17 years, with type 1 diabetes treated with continuous subcutaneous insulin infusion (CSII) (n = 306) or multiple daily injections (MDI) (n = 271). The Insulin Delivery System Rating Questionnaire was validated in Italian and was self-completed by the subjects during a routine visit to the centres. Subjects were compared following the domains of the questionnaire. Good HRQOL was seen in subjects treated with either MDI or CSII. Significant differences were not found in the domains for general diabetes, including diabetes worries, social burden and psychological well-being. Multiple quantile regression analysis showed that CSII confers significant advantages in terms of HRQOL with improvements in treatment satisfaction, perceived clinical efficacy and reduction in treatment interference with daily activities. This favourable impact was more evident in subjects reporting lower HRQOL scores, suggesting that CSII may be especially useful for individuals perceiving a poor HRQOL. Analysis of the domains indicated that CSII was associated with a higher HRQOL than MDI. Life-course HRQOL evaluation using a standardised questionnaire can ensure better chronic disease management. This is particularly important when providing individualised care for adolescents, as they become increasingly responsible for managing their diabetes.

Transanal endoscopic microsurgery for rectal tumors: an option to radical surgery?

AIM: We present our experience in the treatment of rectal adenomas and selected cases of distal rectal cancer without evidence of nodal or distant metastasis (N0-M0) managed by transanal endoscopic microsurgery (TEM). This study examines our experience evaluating surgical morbidity, mortality and oncological outcome. METHODS: Eight hundred ten patients with rectal lesions (462 adenomas, 115 T1, 130 T2 and 103 T3) were enrolled. All patients staged preoperatively as T2 and T3 underwent preoperative high dose radiotherapy and since 1997 patients with less than 70 year old and good general conditions also preoperative chemotherapy. RESULTS: Minor complications were observed in 69 patients (8.5%) whereas major complications only in 5 patients (0.6%). Definitive histology confirmed adenomas in 431 cases (93%), while in 310 malignant lesions we had: 51 pT0 (14.7%), 127 pT1 (36.5%), 139 pT2 (39.9%) and 31 pT3 (8.9%). Sixteen (4.6%) patients (9 pT2 and 7 pT3) developed local recurrence whereas 6 (1.7%) patients distant metastasis. The survival rate at the end of follow-up was 100% for pT1 and 90% and 77% for pT2 and pT3 patients. CONCLUSION: TEM is safe and effective for rectal adenomas not removable endoscopically. T1 cancer may undergo local excision alone, while T2 and T3 lesions require preoperative radiochemotherapy. The results reported seems to be not very different in terms of local recurrence and survival rate to those after conventional surgery.

Changing characteristics and risk factors of patients with and without incident HCV infection among HIV-infected individuals.

BACKGROUND: Chronic hepatitis C virus (HCV) infection has become a leading cause of non-acquired immunodeficiency syndrome (AIDS)-related morbidity and mortality for human immunodeficiency virus (HIV)-infected persons in the highly active antiretroviral therapy (HAART) era. Despite injection drug use (IDU) remaining the main route of HCV infection, recent reports indicate outbreaks of acute HCV infection among HIV-infected men who have sex with men (MSM) and sexually transmitted infections in the absence of IDU. METHODS: We conducted a retrospective observational study of behavioural and demographic factors of patients with and without incident HCV infection among HIV-infected individuals followed at the AIDS Clinic of the Infectious Disease Department of the University of Ancona from 1989 to 2011. RESULTS: Overall, 440 patients were considered; a total of 145 patients had initial positive HCV antibody test results (HCV+); a total of 295 patients had initial negative HCV antibody test results (HCV-). In the latter population, 14 seroconverted to HCV antibody (neoHCV), with an overall incidence of 0.59 per 100 person-years. While IDU was the principal risk factor of HCV+, the main route of transmission of incident HCV infection was sexual transmission. The HCV- group was significantly older than the other two groups and showed a significantly lower CD4 count at HIV diagnosis than neoHCV. Being Italian and having a low level of education were significantly more represented in HCV+. Younger age at HIV infection, IDU and additional risk factors other than sexual transmission significantly affected the probability of being HCV+. The cumulative probability of developing HCV infection in the HCV- group was calculated to be 6% at 15 years. CONCLUSIONS: The epidemiology of the newly acquired HCV in HIV+ persons is changing. Therefore, a frequent and constant counselling about HCV infection is desirable and a periodical screening test is mandatory.

Randomized clinical trial of endoluminal locoregional resection versus laparoscopic total mesorectal excision for T2 rectal cancer after neoadjuvant therapy.

BACKGROUND: In selected patients with early low rectal cancer, locoregional excision combined with neoadjuvant therapy may be an alternative treatment option to total mesorectal excision (TME). METHODS: This prospective randomized trial compared endoluminal locoregional resection (ELRR) by transanal endoscopic microsurgery versus laparoscopic TME in the treatment of patients with small non-advanced low rectal cancer. Patients with rectal cancer staged clinically as cT2 N0 M0, histological grade G1-2, with a tumour less than 3 cm in diameter, within 6 cm of the anal verge, were randomized to ELRR or TME. All patients underwent long-course neoadjuvant chemoradiotherapy. RESULTS: Fifty patients in each group were analysed. Overall tumour downstaging and downsizing rates after neoadjuvant chemoradiotherapy were 51 and 26 per cent respectively, and were similar in both groups. All patients had R0 resection with tumour-free resection margins. At long-term follow-up, local recurrence had developed in four patients (8 per cent) after ELRR and three (6 per cent) after TME. Distant metastases were observed in two patients (4 per cent) in each group. There was no statistically significant difference in disease-free survival (P = 0·686). CONCLUSION: In selected patients, ELRR had similar oncological results to TME. Unique Protocol ID: URBINO-LEZ-1995; registration number: NCT01609504 (http://www.clinicaltrials.gov).

Effect of Coenzyme Q10 in mitigating oxidative DNA damage in Down syndrome patients, a double blind randomized controlled trial.

Down syndrome (DS) is a chromosomal abnormality (trisomy 21) associated with a complex phenotype. Oxidative stress is known to play a major role in this pathology both due to genetic and epigenetic factors, suggesting that oxidative imbalance contributes to the clinical manifestation of DS. In particular, the implications of oxidative DNA damage in Down syndrome has been linked with neurodegeneration. Here we report the results of a double blind controlled trial aimed at investigating the protective effect of Coenzyme Q(10) on DNA oxidation in this clinical setting using the single cell gel electrophoresis technique.

Treatment of focal idiopathic hyperhidrosis with Botulinum Toxin Type A: clinical predictive factors of relapse-free survival.

BACKGROUND: No material about the identification of predictive clinical factors of therapeutic response to Botulinum Toxin Type A (BTX-A) in focal idiopathic hyperhidrosis has been found. OBJECTIVE: To evaluate if age, sex, extension rate of hyperhidrotic area, localization, disease-related impairment of life quality, number of previous local, non-invasive treatments different from BTX-A, and duration of disease, may affect the relapse-free survival (RFS) after a BTX-A treatment in palmar and axillary focal idiopathic hyperhidrosis. METHODS: Forty-one patients suffering from palmar hyperhidrosis, and 38 patients suffering from axillary hyperhidrosis received intradermal injections of BTX-A. All patients were clinically screened before and after treatment; they were followed for 15 months after it, according to Hyperhidrosis Disease Severity Scale (HDSS), Minor's test, and DLQI test, to state disease severity, and disease-related impairment of quality of life. RESULTS: The duration of therapeutic effect of BTX-A is not significantly influenced by age (P = 0.783), sex (P = 0.762), extension of hyperhidrotic area (P = 0.770), site of involvement (P = 0.402), disease-induced impairment of life quality (P = 0.745), number of previous therapies (P = 0.730), or site of involvement (P = 0.402). In palmar idiopathic hyperhidrosis, patients with a longer disease history show a shorter duration of RFS after a treatment with BTX-A (P = 0.01). CONCLUSIONS: Patients suffering from palmar hyperhidrosis have a longer lasting disease, and a length of disease more than 20 years in these patients influences the RFS after BTX-A treatment.
