- Abstract
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive muscle weakness. Presence of pain in ALS patients is heterogeneously reported in studies, and mostly underrepresented in symptom scales. The aim of this study is to evaluate the efficacy of pharmacological and non-pharmacological therapeutic modalities for pain management in patients with ALS. A systematic review was conducted in four databases; PubMed, Scopus, Clinicaltrials.gov, and Cochrane-Ovid. Five randomized controlled clinical trials were included regarding pharmacological and non-pharmacological pain management interventions in adult patients with confirmed diagnosis of ALS in whom pain was objectively evaluated. Risk of bias assessment was evaluated using the RoB2.0 tool. Eligible studies were reported as a descriptive analysis. This systematic review was registered with PROSPERO ID: CRD42024495009. Five clinical trials regarding pain management strategies in ALS were eligible for analysis. Two out of five were non-pharmacological approaches whilst the remaining three provided pharmacological therapies. Of these, Mexiletine was efficient in terms of pain relief, particularly between 600 and 900 mg per day, whereas Mecasin showed no pain relief at both, high and low doses. Non-pharmacological therapies, such as exercise and osteopathic manual treatment also lacked efficacy in regard to pain management. Clinical trials focusing on pain management strategies for ALS patients are limited. Medical professionals, understandably focused on immediate life-threatening aspects, may inadvertently sideline the nuanced and intricate dimension of pain experienced by patients with ALS., Competing Interests: Declarations Ethics approval This is a systematic review, therefore no ethics approval was required.

- Abstract
The introduction of closed-loop systems in the pediatric population has been a revolution in the management and evolution of diabetes. However, there are not many published studies in situations in which the feeding, schedules, and activities of the children deviate from the routine for which the systems were programmed, as in the case of a summer camp for children and adolescents with diabetes, where the specific programming of this device is not well known. It was a single-center prospective preliminary study. A total of twenty-seven patients (mean age 11.9 ± 1.9 years, 40% male, duration of diabetes 6.44 ± 2.83 years) were included (twenty with Medtronic MiniMed 780G system and seven with Tandem Control-IQ). Glucometric variables and pump functionality were monitored during the 7-day camp and in the following 3 weeks. There was no decrease from the objective TIR 70% at any moment. The worst results in Time Below Range were at 72 h from starting the camp, and the worst results in Time Above Range were in the first 24 h, with a progressive improvement after that. No episodes of level 3 hypoglycemia or ketoacidosis occurred. The use of specific programming in two integrated systems, with complex blood glucose regulation algorithms and not-prepared-for situations with increased levels of physical activity or abrupt changes in feeding routines, did not result in an increased risk of level 3 hypoglycemia and ketoacidosis for our pediatric type 1 diabetes (T1D) patients, regardless of the closed-loop device.

- Abstract
The COVID-19 pandemic and associated lockdown measures have been associated with substantial disruptions to health care services, including screening for human immunodeficiency virus (HIV) and management of people living with HIV (PLWH). Data from 3265 patients were examined in a retrospective cohort study. We compared outpatient follow-up for PLWH, the number of new patients, treatment adherence, hospitalizations, and deaths during the "pandemic period" (March 2020 to February 2021), the "pre-pandemic period" (the equivalent time frame in 2019), and the "post-pandemic period" (March to September 2021). During the pandemic period, the number of new patients seen at the HIV clinic (116) as well as the requested viral load tests (2414) decreased significantly compared to the pre-pandemic (204 and 2831, respectively) and post-pandemic periods (146 and 2640, respectively) ( p < 0.01 for all the comparisons). However, across the three study periods, the number of drug refills (1385, 1330, and 1411, respectively), the number of patients with undetectable viral loads (85%, 90%, and 93%, respectively), and the number of hospital admissions among PLWH remained constant. Despite the COVID-19 pandemic's impact, our findings show stability in the retention of clinical care, adherence to treatment, and viral suppression of PLWH, with no significant impact on hospitalization rates or all-cause mortality.

- Abstract
Primary and secondary haemophagocytic lymphohistiocytosis (HLH) are hyperferritinaemic hyperinflammatory syndromes with a common terminal pathway triggered by different etiopathogenetic factors. HLH is characterised by a decreased capacity of interferon gamma production with an activated NK phenotype profile similar to other hyperinflammatory syndromes. Viruses are closely linked to the development of HLH as infectious triggers, and the break of tolerance to self-antigens is considered a critical mechanism involved in the development of immune-mediated conditions triggered by viral infections. Emerging studies in patients with COVID-19 are suggesting a key role of monocytes/macrophages in the pathogenesis of this viral infection, and there is a significant overlap between several features reported in severe COVID-19 and the features included in the HLH-2004 diagnostic criteria. Therefore, SARS-Cov-2, as other respiratory viruses, may also be considered a potential etiological trigger of HLH. The frequency of HLH in adult patients with severe COVID-19 is lower than 5%, although this figure could be underestimated considering that most reported cases lacked information about some specific criteria (mainly the histopathological criteria and the measurement of NK cell function and sCD25 levels). Because HLH is a multi-organ syndrome, the diagnostic approach in a patient with severe COVID-19 in whom HLH is suspected must be carried out in a syndromic and holistic way, and not in the light of isolated clinical or laboratory features. In COVID-19 patients presenting with persistent high fever, progressive pancytopenia, and hepatosplenic involvement, together with the characteristic triad of laboratory abnormalities (hyperferritinaemia, hypertriglyceridaemia, and hypofibrinogenaemia), the suspicion of HLH is high, and the diagnostic workup must be completed with specific immunological and histopathological studies.

- Abstract
Objectives: To analyse the clinical features and outcomes of patients presenting with life-threatening systemic disease in a large cohort of Spanish patients with primary Sjögren's syndrome (SS)., Methods: The GEAS-SS multicentre registry was formed in 2005 with the aim of collecting a large series of Spanish patients with primary SS, and included more than 20 Spanish reference centres with substantial experience in the management of SS patients. By January 2018, the database included 1580 consecutive patients fulfilling the 2002 classification criteria for primary SS. Severe, life-threatening systemic disease was defined as an activity level scored as "high" in at least one ESSDAI domain., Results: Among 1580 patients, 208 (13%) were classified as presenting a severe, potentially life-threatening systemic disease: 193 presented one ESSDAI domain classified as high, 14 presented two high scored domains and only one presented three high activity domains. The ESSDAI domains involved consisted of lymphadenopathy in 78 (37%) cases, CNS in 28 (13%), PNS in 25 (12%), pulmonary in 25 (12%), renal in 21 (10%), cutaneous in 19 (9%), articular in 18 (9%), haematological in 7 (3%) and muscular in 4 (2%). Patients with severe systemic disease were more frequently men (p=0.001) and had a higher frequency of anaemia (p<0.001), lymphopenia (p<0.001), rheumatoid factor (p=0.021), low C3 levels (p=0.015), low C4 levels (p<0.001) and cryoglobulins (p<0.001). From a therapeutic point of view, systemic patients received more frequently glucocorticoids (p<0.001), immunosuppressants (p<0.001), intravenous immunoglobulins (p=0.008) and rituximab (p<0.001). We found an overall mortality rate of 20% in severe systemic patients, a rate that reached to 33% in patients presenting two or more high systemic involvements; these patients had a higher frequency of low C4 levels (p=0.012) and cryoglobulins (p=0.001) in comparison with those with a single severe organ involved., Conclusions: 13% of patients with primary SS develop a potentially life-threatening systemic disease (mainly lymphoma, but also severe internal organ involvements including nervous system, the lungs and the kidneys). This subset of patients requires intensive therapeutic management with a mortality rate of nearly 20% of cases.

- Abstract
The wide and rapid spread of Chikungunya (CHIKV) and Zika (ZIKV) viruses represent a global public health problem, especially for tropical and subtropical environments. The early detection of CHIKV and ZIKV in mosquitoes may help to understand the dynamics of the diseases in high-risk areas, and to design data based epidemiological surveillance to activate the preparedness and response of the public health system and vector control programs. This study was done to detect ZIKV and CHIKV viruses in naturally infected fed female Aedes aegypti (L.) mosquitoes from active epidemic urban areas in Ecuador. Pools (n=193; 22 pools) and individuals (n=22) of field collected Ae. aegypti mosquitoes from high-risk arboviruses infection sites in Ecuador were analyzed for the presence of CHIKV and ZIKV using RT-PCR. Phylogenetic analysis demonstrated that both ZIKV and CHIKV viruses circulating in Ecuador correspond to the Asian lineages. Minimum infection rate (MIR) of CHIKV for Esmeraldas city was 2.3% and the maximum likelihood estimation (MLE) was 3.3%. The minimum infection rate (MIR) of ZIKV for Portoviejo city was 5.3% and for Manta city was 2.1%. Maximum likelihood estimation (MLE) for Portoviejo city was 6.9% and 2.6% for Manta city. Detection of arboviruses and infection rates in the arthropod vectors may help to predict an outbreak and serve as a warning tool in surveillance programs., (Copyright © 2017 Elsevier B.V.

- Abstract
The current strategy for managing rheumatoid arthritis (RA) focuses on achieving clinical remission. Once remission is achieved and sustained over time, the most efficient strategy is dose optimization. This work describes the results of dose optimization after 2 years of follow-up in patients with RA treated with biological therapy and identifies predictive variables of response. Cohort: patients from the CREATE registry who, as of 1 November 2013, had been in clinical remission (DAS28 ≤2.6) for at least 6 months., Intervention: Dose optimization was 20-50% of the standard dose. Outcome measurement were effectiveness (percentage of patients who continued to meet criteria for clinical remission) and efficiency (dose reduction and mean savings). Sixty-eight patients with RA were optimized, with initial mean DAS28 of 2.2 ± 0.7. After 2 years of follow-up, the mean DAS28 was 2.4 ± 0.7, a non-statistically significant difference. Twenty-eight patients (41.2%) continued in clinical remission with dose optimization after 2 years. Mean survival time was 14.2 months (95% CI 12.0-16.5). Of the 40 patients who needed to return to a standard dose, 57.5% managed to achieve remission again at 2 years. Mean dose reduction at 2 years was 21.17%, reaching a mean saving of €5576 ± 5099 per patient. In actual clinical practice, over 40% of patients with established RA who had been in sustained clinical remission managed to continue in remission 2 years after receiving optimized doses. The savings achieved was about 21% of the actual direct health costs for patients in the CREATE registry.

- Abstract
Objectives: We have analyzed the parameters (bacterial translocation, immune activation and regulation, presence of HCV coinfection) which could be implicated in an inappropriate immune response from individuals with chronic HIV infection. The influence of them on the evolution of CD4+ T cell count has been investigated., Patients and Methods: Seventy HIV-infected patients [monoinfected by HIV (n = 20), HCV-coinfected (with (n = 25) and without (n = 25) liver cirrhosis)] and 25 healthy controls were included. Median duration of HIV infection was 20 years. HIV- and HCV-related parameters, as well as markers relative to bacterial translocation, monocyte and lymphocyte activation and regulation were considered as independent variables. Dependent variables were the increase of CD4+ T cell count during the follow-up (12 months)., Results: Increased values of bacterial translocation, measured by lipopolysaccharide-binding protein, monocyte and lymphocyte activation markers and T regulatory lymphocytes were detected in HIV-monoinfected and HIV/HCV coinfected patients. Serum sCD14 and IL-6 were increased in HIV/HCV-coinfected patients with liver cirrhosis in comparison with those with chronic hepatitis or HIV-monoinfected individuals. Time with undetectable HIV load was not related with these parameters. The presence of cirrhosis was negatively associated with a CD4+ T cell count increase., Conclusion: In patients with a chronic HIV infection, a persistent increase of lipopolysaccharide-binding protein and monocyte and lymphocyte modifications are present. HCV-related cirrhosis is associated with more elevated serum concentrations of monocyte-derived markers. Cirrhosis influences the continued immune reconstitution of these patients.

- Abstract
Objective: To analyze the etiopathogenic role of genetic polymorphisms and serum levels of surfactant protein-D (SP-D) in primary Sjögren syndrome (pSS)., Methods: We analyzed 210 consecutive patients with pSS. SFTPD genotyping (M11T polymorphism rs721917) was analyzed by sequence-based typing and serum SP-D by ELISA., Results: Thirty-two patients (15%) had the Thr11/Thr11 genotype, 80 (38%) the Met11/Met11 genotype, and 96 (46%) the Met11/Thr11 genotype; 2 patients could not be genotyped. Patients carrying the Thr11/Thr11 genotype had a higher prevalence of renal involvement (13% vs 1% and 4% in comparison with patients carrying the other genotypes, p = 0.014). Serum SP-D levels were analyzed in 119 patients (mean 733.94 ± 49.88 ng/ml). No significant association was found between serum SP-D levels and the SP-D genotypes. Higher mean values of serum SP-D were observed in patients with severe scintigraphic involvement (851.10 ± 685.69 vs 636.07 ± 315.93 ng/ml, p = 0.038), interstitial pulmonary disease (1053.60 ± 852.03 vs 700.36 ± 479.33 ng/ml, p = 0.029), renal involvement (1880.64 ± 1842.79 vs 716.42 ± 488.01 ng/ml, p = 0.002), leukopenia (899.83 ± 661.71 vs 673.13 ± 465.88 ng/ml, p = 0.038), positive anti-Ro/SS-A (927.26 ± 731.29 vs 642.75 ± 377.23 ng/ml, p = 0.006), and positive anti-La/SS-B (933.28 ± 689.63 vs 650.41 ± 428.14 ng/ml, p = 0.007), while lower mean values of serum SP-D were observed in patients with bronchiectasis (489.49 vs 788.81 ng/ml, p = 0.019)., Conclusion: In pSS, high SP-D levels were found in patients with severe glandular involvement, hypergammaglobulinemia, leukopenia, extraglandular manifestations, and positive anti-Ro/La antibodies. The specific association between SP-D levels and pulmonary and renal involvements may have pathophysiological implications.

- Abstract
Objective: To evaluate health-related quality of life in a large series of primary SS patients using the recently-proposed ESSPRI questionnaire and to evaluate the relationship between the intensity of oral dryness and other signs and symptoms frequently found in these patients., Methods: We evaluated 90 primary SS patients seen consecutively; all fulfilled the current classification criteria. All patients completed the ESSPRI questionnaire. We compared the mean values of the ESSPRI-dry mouth item with other ESSPRI items related to sicca features, general symptoms, quality of life, quality of sleep, psychological and psychiatric features, extraglandular involvement, laboratory features and immunological markers and cardiovascular risk factors. Multivariate regression analysis with a backwards stepwise selection method was performed to identify those variables that were independently associated with dry mouth., Results: Mean intensity of oral dryness measured by the corresponding ESSPRI item was 7.17±0.23. Oral dryness correlated with age both at diagnosis and at study inclusion (p=0.013), but not with gender or with time of disease evolution. No significant correlation was found with the SF-36, HAQ and FIQ questionnaires. We found a significant correlation between the intensity of oral dryness and the quality of sleep (p=0.001), anxiety and depression measured by the GH28 (p=0.004 and 0.024, respectively), and a statistically-significant trend for anxiety and depression measured by the HADS (p=0.08 and 0.07, respectively). No significant correlation was found with the main extraglandular and immunological features; however, a significant correlation between oral dryness and hypertension (p=0.019), type II diabetes mellitus (p=0.005) and hypercholesterolemia (p=0.011) was found. Multivariate regression analysis shows that fatigue measured by ESSPRI (p=0.049), sleep quality (p=0.008) and hypercholesterolemia (p=0.008) were independently associated with dry mouth., Conclusion: We report on the usefulness of the ESSPRI index in evaluating HRQOL associated with oral dryness in primary SS patients. Oral dryness correlated with age and the other sicca symptoms measured by ESSPRI, but not with the main systemic and immunological SS features. In contrast, oral dryness was strongly correlated with fatigue, pain, psychological distress, poor sleep and vascular risk factors. A multidisciplinary therapeutic approach may be the best way of minimizing oral dryness and its consequences in primary SS patients.

- Abstract
Objectives: This paper aims to analyse the etiology, characterisation and outcomes of the different types of peripheral neuropathy in patients with primary Sjögren's syndrome (SS) and their association with clinical and immunological disease expression., Methods: A total of 563 consecutive patients diagnosed with primary SS were evaluated. We retrospectively assessed the results of nerve conduction studies carried out in patients with suspected peripheral nervous system involvement. Peripheral neuropathies were classified into mononeuropathy, mononeuropathy multiplex, polyneuropathy and neuronopathy according to the patterns evidenced by electrodiagnostic studies., Results: Nerve conduction studies were carried out in 158/563 (28%) SS patients. The results were normal in 49 and abnormal in 109 patients, in whom peripheral neuropathy was diagnosed in 102. After excluding patients with neuropathy associated with other diseases and patients with entrapment mononeuropathies, 55/563 (10%) patients were classified as having SS-related peripheral neuropathy, including axonal sensorimotor polyneuropathy (n=24), pure sensory neuronopathy (n=15), mononeuropathy multiplex (n=15) and demyelinating polyradiculoneuropathy (n=1). In spite of therapy, clinical progression measured by the MOHS scale was observed in 12% of patients with axonal polyneuropathy, 13% of those with mononeuropathy multiplex and 47% of those with neuronopathy. Survival was significantly reduced in patients with peripheral neuropathy (especially in those with mononeuropathy multiplex and axonal polyneuropathy) in comparison with the control group (log rank =0.001)., Conclusions: We found a prevalence of SS-related peripheral neuropathy of 10%. Classification of neuropathy according to the clinical presentation and electrodiagnostic tests may be useful in determining the functional outcome, therapeutic response and survival.

- Abstract
Objective: The objective of this study was the analysis of the prevalence and type of primary resistance to antiretroviral drugs in patients diagnosed with HIV infection, and to determine the most appropriate empirical treatment to obtain a virological and immunological response., Patients and Methods: An observational analysis of patients with a de novo diagnosis of HIV infection during the period 2008-2010. Clinical, immunological and virological characteristics, including genotype analysis of resistance to antiretrovirals, were considered as independent variables. The dependent variable was an undetectable HIV viral load after six months of treatment. Data are provided as median (interquartile range) and absolute number (percentage)., Results: Seventy-three patients with a de novo diagnosis of HIV infection were included [53 males (73%); 36 (30-46) years-old; prior use of intravenous drugs: 5 patients (7%); hepatitis C virus co-infection: 13 individuals (18%)]. Ten patients (14%) showed symptoms attributable to acute HIV infection. A CD4+ T cell count lower than 350 mm(3) was detected in a 37% (n=27) of all patients. The initiation of antiretroviral therapy followed the GESIDA recommendations (no therapy: 20 patients; tenofovir+emtricitabine+efavirenz: 28 patients; abacavir+lamivudine+efavirenz: 1 patient; tenofovir+emtricitabine+protease inhibitors: 5 patients; abacavir+lamivudine+protease inhibitors: 1 patient; 18 patients were lost in the follow-up). After starting antiretroviral therapy, the resistance analyses detected the existence of primary resistance to antiretrovirals in 12.7% (confidence interval 95%: 3-22) of the patients, distributed as follows: isolated resistance to, nucleosides was detected in 2% (M184V), to nevirapine/efavirenz in 9% (K103N), and combined resistance to nucleosides and non-nucleosides in 2%; there were no cases of resistance to protease inhibitors. Consequently, antiretroviral therapy was changed in 5 (14%) out of 35 patients, attaining an undetectable HIV viral load at 6 months in all of them. The primary resistance to antiretrovirals was not related with epidemiological, virological (including infection by non B subtype) or immunological variables., Conclusions: In the present study, a change in the epidemiological pattern of de novo diagnosis of HIV infection in our area has been observed. The existence of resistance mutations in more than 5% of the new cases is noteworthy. This finding must be considered in order to establish the rules of empirical treatment in our area., (Copyright © 2011 Elsevier España, S.L. All rights reserved.)

Objective: To analyze the monoclonal expression of SS through the detection of serum monoclonal immunoglobulins (mIgs) in a large series of patients with Sjögren syndrome (SS), focusing on the etiology, characterization and evolution of the monoclonal band and the association with SS clinical expression and outcomes., Methods: Serum immunoelectrophoresis (IE) was performed to 408 consecutive patients who were evaluated by our unit between 1992 and 2011: 221 patients who fulfilled the 2002 American-European criteria for primary SS, 122 primary SS patients who fulfilled exclusively the 1993 European criteria and 65 patients with SS-associated hepatitis C virus infection. IE was performed at diagnosis and every year during the follow-up., Results: Of the 221 patients with primary SS, 48 (22%) had monoclonal gammopathy. In the control groups, the prevalence was 16% in patients with SS who fulfilled the 1993 criteria (p > 0.05) and 52% in SS-HCV patients (p < 0.001). Monoclonal bands were characterized in 47/48 patients with primary SS: IgG (n = 21), IgM (n = 16), IgA (n = 5) and free light chains (n = 5); the light chain was κ in 28 patients and λ in 19 (κ:λ ratio 1.5). Primary SS patients with monoclonal gammopathy had a higher prevalence of parotidomegaly (38% vs 20%, p = 0.021), vasculitis (21% vs 6%, p = 0.003), neurological involvement (42% vs 23%, p = 0.016), higher mean values of circulating gammaglobulins (23.4 vs 20.6%, p = 0.026), ESR (56.6 vs 37.6 mm/h, p = 0.003), a higher prevalence of RF (69% vs 50%, p = 0.022), low C3 levels (24% vs 11%, p = 0.028), low C4 levels (24% vs 7%, p = 0.003), low CH50 activity (28% vs 11%, p = 0.008) and cryoglobulins (23% vs 8%, p = 0.012) compared with those without monoclonal gammopathy. Of the 48 patients with primary SS and monoclonal gammopathy, 8 developed hematologic neoplasia after a mean follow-up of 10 years, a higher prevalence than observed in patients without monoclonal gammopathy (17% vs 5%, p = 0.009). Survival rates according to the presence or absence of monoclonal gammopathy were 83% and 97%, respectively (log rank 0.004)., Conclusion: Monoclonal gammopathy was detected in 22% of patients with primary SS fulfilling the 2002 criteria, with mIgGκ being the most frequent type of band detected. In HCV-associated SS patients, the prevalence was higher (52%) with IgMκ being the most prevalent band detected. Monoclonal gammopathy was associated with a higher prevalence of parotid enlargement, extraglandular features, hypergammaglobulinemia, cryoglobulinemia and related markers (rheumatoid factor, hypocomplementemia), and with a poor prognosis (development of neoplasia and death)., (Copyright © 2012 Elsevier Ltd.

- Abstract
Objective: To analyze the impact of highly active anti-retroviral therapy (HAART) on the admissions and mortality of patients with human immunodeficiency virus (HIV) infection and of all patients cared in an Internal Medicine Department., Methods: A retrospective study with analysis of admissions and deaths in the Internal Medicine Department of a third-level care hospital between January 1996 and December 2000. HAART was introduced starting in 1997. Age, gender, main diagnosis at discharge, diagnosis related group (DRG) weight, death cause, and hospital stay were assessed globally and annually., Results: During the study period 7,580 admissions took place, of which 939 were secondary to HIV infection related diseases. The incidence of HIV-related admissions declined in 32.9% and the case-fatality rate in 67.8% between 1996 and 2000, with increase at the same time of the number of patients with noninfectious respiratory pathology and of overall number of patients with infections. Average hospital stay of patients cared in the Internal Medicine Department remained stable, with reduction of 31.5% of that of the group with HIV infection starting in 1997. DRG complexity in this group decreased 0.56 points., Conclusions: The introduction of HAART has been associated to a reduction in the incidence of admissions, in the complexity of the diagnoses, and in the mortality in the group of patients with HIV infection. At the same time there was an increased in the number of patients with respiratory and infectious pathology different from that related to HIV.
