Risk factors related to oral candidiasis in patients with primary Sjögren's syndrome.

BACKGROUND: Candidiasis is the most frequent mycotic infection of the oral cavity. The aim of this study was to investigate the presence of clinical oral candidiasis and Candida albicans yeast in a population diagnosed of primary Sjögren's syndrome (pSS) and to study the possible factors associated with this infection. MATERIAL AND METHODS: An observational cross-sectional study was conducted in 61 pSS patients (60 women, 1 man, mean age 57.64±13.52) where patient based information (demographic and medical, tobacco and alcohol consumption history), intraoral parameters (presence of dentures, clinical signs of candidiasis), salivary analytical information (number of Candida albicans as colony-forming units per millilitre (CFU/mL), salivary pH levels, unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) were collected. RESULTS: 13.1% of pSS patients presented oral signs of candidiasis. Denture stomatitis and angular cheilitis were the most common lesions. 87.5% of patients with clinical candidiasis presented reduced pH levels and salivary flow in both UWS and SWS. A significant statistical negative correlation was found between CFU/mL of Candida albicans and levels of UWS and SWS. A negative correlation was found between pH levels and CFU/mL, although not statistically significant. CONCLUSIONS: A reduced salivary flow may predispose pSS patients to Candida albicans overgrowth, which may show with clinical signs. Preventive measures are of great importance to avoid and to treat this condition promptly.

Oral lesions in patients with primary Sjögren's syndrome. A case-control cross-sectional study.

BACKGROUND: To evaluate the presence of oral lesions in a group of patients with primary Sjögren's syndrome (pSS) and compare these results with a matched control group (CG). MATERIAL AND METHODS: An observational cross-sectional study was conducted. 61 pSS patients (60 women, 1 man, mean age 57.64±13.52) diagnosed according to the American European Criteria (2002), and 122 matched control patients (120 women, 2 men, mean age 60.02±13.13) were included. Demographic and medical data, oral lesions and salivary flow rate were collected. RESULTS: Compared with the controls, pSS patients were 3.95 more likely to have oral lesions (OR 3.95; 95% CI 2.06-7.58; p=0.0001). 57.4% pSS patients presented oral lesions compared to 25.4% in CG. The most common were candidiasis (13.1% vs 2.5%), traumatic lesions (13.1% vs 4.1%), apthae (8.2% vs 0), and fissuration of the tongue (8.2% vs 0.8%). pSS patients with oral lesions had lower salivary flow levels (stimulated and unstimulated), although these differences were not significant. Significant associations were found between the presence of oral lesions and systemic manifestations and history of parotid gland enlargement in pSS patients. CONCLUSION: pSS patients suffer more oral lesions than general population and these lesions may aggravate the pSS disease.

Oral lesions in Sjogren's syndrome: A systematic review.

BACKGROUND: Sjogren's syndrome (SS) is an autoimmune disease related to two common symptoms: dry mouth and eyes. Although, xerostomia and hyposialia have been frequently reported in these patients, not many studies have evaluated other oral manifestations. The aim of this systematic review was to investigate prevalence rates of oral lesions (OL) in SS patients and to compare it to a control group (CG), when available. MATERIAL AND METHODS: An exhaustive search of the published literature of the Pubmed, Scopus, Web of Science and the Cochrane Library databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) for relevant studies that met our eligibility criteria (up to September 1st 2017). RESULTS: Seventeen cross-sectional studies and one cohort study were finally included. The results showed that SS patients presented more OL compared to non-SS patients. The most frequent types of OL registered in primary and secondary SS were angular cheilitis, atrophic glossitis, recurrent oral ulcerations and grooves or fissurations of the tongue, also when compared to a CG. CONCLUSIONS: OL are common and more frequent in SS patients when compared to a CG. This may be a consequence of low levels of saliva. More studies where these OL and all the possible cofounding factors are taken into account are needed.

Effectiveness of semi-permeable dressings to treat radiation-induced skin reactions. A systematic review.

The aim of this systematic review is to assess the available evidence concerning the effectiveness of semi-permeable dressings, on the full range of skin reactions, related to radiation therapy in cancer patients, from local erythema to moist desquamation, including subjective symptoms such as pain, discomfort, itchiness, burning and the effect on daily life activities. The bibliographic search was carried out looking for Randomised Clinical Trials (RCTs) indexed in PubMed, Cinhal, Cochrane plus and Biblioteca Nacional de Salud, published in the English and Spanish language, between 2010 and 2015. Data extraction and evaluation of study quality was undertaken by peer reviewers using the Critical Appraisal Skills Programme (CASP). Of 181 studies, nine full texts were assessed. Finally, six RCT were included in the final synthesis: three analysed the application of Mepilex® Lite in breast cancer and head & neck cancer; one evaluated the application of Mepitel® Film in breast cancer; and two assessed the use of silver nylon dressings in breast cancer and in patients with lower gastrointestinal cancer. The results show that semi-permeable dressings are beneficial in the management of skin toxicity related to radiation therapy. However, rigorous trials showing stronger evidence are needed.

The autoimmune disease-associated IL2RA locus is involved in the clinical manifestations of systemic sclerosis.

Regulatory T cells (T(regs)) are crucial in the maintenance of the immune tolerance and seem to have an important role in systemic sclerosis (SSc). The interleukin 2 receptor α (IL2RA) is an important T(reg) marker, and polymorphisms of IL2RA gene are associated with a number of autoimmune diseases. Therefore, we aimed to investigate for the first time the association of the IL2RA locus in SSc. For this purpose, a total of 3023 SSc patients and 2735 matched healthy controls, from six European Caucasian cohorts, were genotyped for the IL2RA gene variants rs11594656, rs2104286 and rs12722495 using the TaqMan allelic discrimination technology. The overall meta-analysis reached statistical significance when the three polymorphisms were tested for association with SSc, the limited subtype (lcSSc) and anti-centromere auto-antibodies (ACAs). However, no significant P-values were obtained when the ACA-positive patients were removed from the SSc and lcSSc groups, suggesting that these associations rely on ACA positivity. The strongest association signal with ACA production was detected for rs2104286 (P(FDR)=2.07 × 10(-4), odds ratio=1.30 (1.14-1.47)). The associations of rs11594656 and rs12722495 were lost after conditioning to rs2104286, and allelic combination tests did not evidence a combined effect, indicating that rs2104286 best described the association between IL2RA and ACA presence in SSc.

No evidence of association between functional polymorphisms located within IL6R and IL6ST genes and systemic sclerosis.

Systemic sclerosis (SSc) is a complex autoimmune disease which genetic component has not been yet completely understood. IL6 encodes a cytokine with a crucial role in the development of autoimmunity and fibrosis and its actions mainly are controlled by IL-6 receptor (IL-6R). We aimed to investigate whether the functional genetic variants rs8192284 and rs2228044 previously associated with several autoimmune diseases, located within the IL-6 receptor (IL-6R) subunits IL6R and IL6ST genes, respectively, are involved in the susceptibility to SSc and/or its major clinical subphenotypes. A Spanish cohort including 1013 SSc patients and 1375 controls was genotyped using the TaqMan® allelic discrimination technology. SSc patients were subdivided according to the major clinical forms, autoantibody status and presence of fibrotic lung affection. Our data showed no influence of the selected variants in global SSc susceptibility (rs8192284: P=0.67, odds ratios (OR)=0.98; rs2228044: P=0.99, OR=1.00). Similarly, the clinical/autoantibody subphenotype analyses did not yielded significant results. Our data suggest that the analyzed polymorphisms may not play a significant role in the SSc susceptibility.

Multicenter longitudinal study of B-lymphocyte depletion in refractory systemic lupus erythematosus: the LESIMAB study.

OBJECTIVE: This study aimed to investigate the effectiveness and safety of single and repeated courses of rituximab in patients with refractory lupus. METHODS: LESIMAB is a multicenter, retrospective, longitudinal study of lupus patients who have not responded to standard therapy and have been treated with rituximab. Response rates at six months and at follow-up were defined as efficacy outcomes. Complete response was defined as a SELENA-SLEDAI score ≤ two and a SELENA-SLEDAI Flare Index of zero. Partial response was defined as a reduction in the SELENA-SLEDAI score of ≥four points with no new or worsening of symptoms. Adverse events were collected. RESULTS: Seventy-three (62.9%) of 116 patients achieved a response at six months (complete in 22 and partial in 51). Ninety-seven (77.6%) of 128 patients achieved a response after a mean follow-up of 20.0 ± 15.2 months (complete in 50 and partial in 47). High baseline SLEDAI score, previous treatment with ≥100 mg/day prednisone, and no history of severe hematologic flare were associated with response after the first treatment course. The median time to response was 6.5 months (95% CI, 5.0-8.0). Thirty-seven patients (38.1%) relapsed after the first infusion. The flare was severe in seven cases and mild to moderate in 29 cases. Serious infection rate was 12.6/100 patient-years. A schedule of four weekly doses was associated with more serious infections. Six patients died: two of infection and four of lupus complications. CONCLUSION: Rituximab can be an effective treatment option for patients who have refractory lupus with severe or life-threatening disease with an acceptable tolerance profile.

[Management of communication between inpatients isolated due to COVID-19 and their families]. / Gestión de la comunicación de los pacientes hospitalizados, aislados con sus familias por la COVID-19.

BACKGROUND AND GOAL: Quality of healthcare has been affected by the current dimensions of the COVID-19 pandemic and the strict hospital isolation to which some inpatients have been subjected. Therefore, we propose to describe the process designed to facilitate the communication of inpatients with their families to detect their needs and perform individualized treatments in each case. METHOD: Qualitative study with action research methodology, responding to the following algorithm: plan the action, diagnosis of the need and hypothesis-action; apply the action, creation of the group of case managers and training of the members; observe the action, collect and analyse the information. During the month of April 2020. RESULTS: 1,754 interactions were undertaken, that affected 490 inpatients. Case Managers made 767 calls, to provide information about admissions (71.45%), changes in inpatient location or operation of units (18.84%), among others. One thousand and ninety-eight calls from family members were received requesting medical information (43.8%), to talk to inpatients (18.48%), to deliver personal articles or manage lost objects (12.84%), and seeking information about patient location or medical discharge (10.20%). Sixty-six percent of the requests were solved by Case Managers, 30% were referred on and 4% could not be solved. CONCLUSIONS: Implementation of the Case Manager Group contributed to encourage communication of inpatients isolated due to COVID-19 with their families, responding to needs raised, improving quality of care and promoting humanization of care.

Accuracy of physical examination in subacromial impingement syndrome.

OBJECTIVE: Shoulder pain is a common complaint, frequently caused by subacromial impingement syndrome (SIS). There are a number of physical examination (PE) manoeuvres that explore the subacromial space. MRI provides an accurate anatomic image of the subacromial space, being the current gold standard in the diagnosis of SIS. The aim of this study is to evaluate the accuracy of the PE in the diagnosis of SIS and/or subacromial-subdeltoid bursitis (SSB) confirmed by MRI. METHODS: Consecutive outpatients with an episode of shoulder pain were prospectively included in the study. They were examined by a rheumatologist and, within 3 days, an MRI was done. Sensitivity, specificity, positive and negative predictive values, and accuracy of PE manoeuvres were calculated using a 2 x 2 table. RESULTS: Fourteen males and 16 females were included. All the tests exhibited acceptable sensitivity. As a result Yocum manoeuvre was considered the most sensitive and most accurate for SIS. With regard to SSB, the Gerber test was the most sensitive. The majority of the PE manoeuvres showed low specificity. CONCLUSIONS: Most PE manoeuvres identify reasonably well subacromial impingement of the shoulder, although, in general, they have low specificity. The Yocum test has the best sensitivity and precision. Our data suggest that imaging techniques should be recommended to better define shoulder lesions.

Long-term continuous ambulatory peritoneal dialysis reduces the expression of CD11b, CD14, CD16, and CD64 on peritoneal macrophages.

OBJECTIVE: To characterize phenotypically the macrophages from nocturnal peritoneal effluent (NPE) in patients on continuous ambulatory peritoneal dialysis (CAPD), and to determine the influence of the length of this therapy on macrophage (M phi) function. DESIGN: Cross-sectional descriptive study. PATIENTS: Fifty-five patients on CAPD who were classified into short-, medium-, and long-term groups according to their time on CAPD. Peritoneal macrophages (PM phi) were also characterized in 7 patients at the time of catheter placement, and there were 13 normal controls. INTERVENTIONS: Macrophages were collected from NPE by centrifugation. MEASUREMENTS: Membrane receptor expression was evaluated by flow cytometry analysis. RESULTS: Flow cytometry analysis revealed that the expression of CD11b, CD16, CD64, and CD14 on NPE macrophages was reduced during the course of CAPD treatment, reaching levels which represented a 40%-50% reduction of the cell surface expression detected at the start of the treatment or on normal control macrophages. Both normal and CAPD PM phi expressed CD4, CD69, and CD71 very weakly and lacked CD25. No changes in HLA-DR or in other adhesion protein (CD11a, CD11c, CD18, CD54) expression were detected, and levels were similar in both patients and normal controls. CONCLUSION: Our results show that long-term CAPD might affect Fc gamma receptor-mediated phagocytosis by reducing the expression of CD16, CD64, and CD11b. Lower CD11b and CD14 expression would also impair PM phi adhesion to mesothelial structures.

[Changes in preovulatory molecular progesterone/estradiol ratio in patients treated with controlled ovarian hyperstimulation. Can they be used in the assessment of ovarian reserve?]. / Cambios en la relación molecular preovulatoria entre estradiol y progesterona en pacientes sometidas a hiperestimulación ovárica controlada. Pueden usarse como evaluación de la reserva ovárica?

The objective was to evaluate if the preovulatory molecular ratio between progesterone and estradiol has age-dependent changes in patients undergoing controlled ovarian hyperstimulation. There were 180 cycles of conventional in vitro fertilization which were studied. Patients were divided in three groups: Group 1 (age less than 30 years; n = 40), group 2 (age between 30 and 35 years; n = 82), and group 3 (age between 36 and 40 years; n = 58). Leuprolide acetate was used in all cases. Molecular progesterone/estradiol ratio was calculated with the following formula: [Serum progesterone (ng/mL) x 3180 (Sl x 10(3)) + serum estradiol (pg/mL) x 3.671 (Sl)]. In patients older than 38.5 years there was positive correlation between preovulatory progesterone and estradiol (R = 0.55, R2 = 0.30). There were significant difference in molecular progesterone/estradiol ratio between group 1 compared to group 2 (P less than 0.001), group 1 compared to group 3 (P less than 0.0001), as well as group 1 compared to group 2 plus group 3 (P less than 0.0001). It is concluded that molecular progesterone/estradiol ratio decreases before any endocrine evidence of ovarian aging. The value of this putative test of ovarian reserve is discussed.

Utility of the Technicon H-1 flags in the detection of peripheral blood blast cells of paediatric acute leukaemia patients.

This study evaluates the sensitivity and positive predictive value of some of the morphological flags supplied by the Technicon H-1 haematological analyser to detect circulating blasts. A total of 1,269 venous blood samples from 91 paediatric patients diagnosed of acute leukemia were analysed in the Technicon H-1. A conventional microscopic manual method was used for reference. The prevalence was 17.7% for the presence of blasts. The results showed that all samples with more than 5% blasts were detected by some WBC morphological flag: only 5 samples (2.2%) with less than 5% blasts showed no morphological flag. In most cases (86%), the flags observed were either the 'Atyp' flag or the 'Blast' flag or both simultaneously. The positive predictive value obtained by the 'Blast' flag for the true presence of blasts was 66.8%, and for the 'Atyp' flag 34.9%; it was 75.8% when both flags were present simultaneously. False positives were associated with postchemotherapy monocytosis or severe neutropenia.
