Patient Experience of Lichen Planus: A Qualitative Exploration of Signs, Symptoms, and Health-Related Quality of Life Impacts.

INTRODUCTION: Lichen planus (LP) is an inflammatory skin disorder that can present in various forms across the body, including lesions on the skin (cutaneous LP [CLP]), scalp (lichen planopilaris [LPP]), and mucosal regions (mucosal LP [MLP]). Qualitative exploration of the patient experience of LP, notably symptoms and impacts on health-related quality of life (HRQoL), is limited. A scarcity of research was also identified relating to emotional wellbeing impacts of CLP patients. Two qualitative studies were conducted with LP patients to address these gaps. METHODS: Study 1 consisted of exit interviews conducted with a subset of adult patients with MLP (n = 5), CLP (n = 4), and LPP (n = 4) enrolled in an LP clinical study in the United States (US) to explore the patient experience. Study 2 consisted of independent qualitative interviews conducted with adult CLP patients (n = 13) from the US and Germany to further explore impacts on emotional wellbeing. RESULTS: Exit interviews found that itch , pain, and skin lesions were most frequently reported as signs/symptoms of LP. Itch and skin lesions were experienced across all LP subtypes, while pain was only reported by CLP and MLP patients. These signs/symptoms impacted HRQoL including emotional wellbeing (frustration, embarrassment), daily activities (oral hygiene, clothing options), social functioning (intimacy, social activities), and physical functioning (chewing/swallowing, opening/moving mouth). Impacts on activities of daily living (ADL) and physical functioning were mostly experienced by MLP patients. Independent qualitative interviews, which further explored impacts of CLP on patients' emotional wellbeing, identified frustration, worry, sadness, embarrassment, and depression as the most frequently experienced. CONCLUSION: The findings contribute to the literature by providing qualitative insights into signs/symptoms and HRQoL impacts of LP, from the adult patient perspective. The findings also highlight the importance of considering assessment of HRQoL impacts in future clinical LP research, particularly impacts on emotional wellbeing when selecting instruments for assessment of HRQoL in the CLP population.

Role of the dental surgeon in the early detection of adults with underlying HIV infection/AIDS.

A review is made of the late diagnosis of human immunodeficiency virus (HIV) infection, a subject of growing interest in public health. It has been estimated that in Europe 30% of all HIV-infected people are unaware of their seropositive condition, and this in turn is associated with a poorer long-term disease prognosis and an increased risk of transmission to other individuals. The role of the dental surgeon in this context could be of great importance, since there are many oral lesions that can suggest the existence of underlying infection. The study also addresses the controversial subject of rapid HIV testing, and whether these tests should be performed on a routine basis in the dental clinic, or whether it is preferable to refer the patient to a specialized center.

Differences in saliva ACE2 activity among infected and non-infected adult and pediatric population exposed to SARS-CoV-2.

BACKGROUND: Variations in the ACE2 activity in saliva could explain the striking differences of susceptibility to infection and risk of severe disease. METHODS: We analyze the activity of ACE2 in saliva in different population groups across a wide age range and disease status during April to June 2020, before SARS-CoV-2 vaccine implementation, and we establish differences between infected people and participants considered resistant (highly exposed healthcare workers and children who cohabited with parents with COVID-19 without isolation and remain IgG negative). RESULTS: We included 74 adults, of which 47 (64%) were susceptible and 27 (36%) were resistant, and 79 children, of which 41 (52%) were susceptible and 38 (48%) were resistant. Resistant adults have significantly lower ACE2 activity in saliva than susceptible adults and non-significant higher values than susceptible and resistant children. ACE2 activity is similar in the susceptible and resistant pediatric population (p = 0.527). In contrast, we observe an increase in activity as the disease's severity increases among the adult population (mild disease vs. severe disease, 39 vs. 105 FU, p = 0.039; severe disease vs. resistant, 105 vs. 31 FU, p < 0.001). CONCLUSIONS: using an enzymatic test, we show that ACE2 activity in saliva correlates with the susceptibility to SARS-Cov-2 infection and disease severity. Children and adults with low-susceptibility to SARS-Cov-2 infection showed the lowest ACE2 activity. These findings could inform future strategies to identify at-risk individuals.

Uptake of tenofovir-based antiretroviral therapy among HIV-HBV-coinfected patients in the EuroSIDA study.

BACKGROUND: According to guidelines all HIV-HBV-coinfected patients should receive tenofovir-based combination antiretroviral therapy (cART). We aimed to investigate uptake and outcomes of tenofovir-based cART among HIV-HBV patients in the EuroSIDA study. METHODS: All hepatitis B surface antigen (HBsAg)+ patients followed up after 1 March 2002 were included. Changes in the proportion taking tenofovir-based cART over time were described. Poisson regression was used to investigate the relationship between tenofovir use and clinical events. RESULTS: 953 HIV-HBV patients were included. Median age was 41 years and patients were predominantly male (85%), White (82%) and ART-experienced (88%). 697 and 256 were from Western and Eastern Europe, respectively. 55 started cART during follow-up, the proportion starting with CD4+ T-cell count <350 cells/mm3 decreased from 85% to 52% in the periods 2002-2006 to 2007-2015. Tenofovir use, among those taking cART, increased from 4% in 2002 to 73% in 2015. Compared to West, tenofovir use was lower in East in 2005 (7% versus 42%), and remained lower in 2015 (63% versus 76%). Among 602 patients taking tenofovir-based cART during follow-up, 155 (26%) discontinued tenofovir. 27 of all discontinuations were due to adverse effects. Only 14 started entecavir and/or adefovir after tenofovir discontinuation, whereas 10 started pegylated interferon. Tenofovir use was not significantly associated with lower risk of liver-related clinical events (n=51), adjusted incidence rate ratio (IRR) 0.64 (95% CI 0.35, 1.18) for comparing patients on tenofovir with those off tenofovir. CONCLUSIONS: Although use of tenofovir-based cART among HIV-HBV patients has increased across Europe, a substantial proportion are still starting cART late and are receiving suboptimal HBV therapy.

The magnitude of week 4 HCV RNA decay on pegylated interferon/ribavirin accurately predicts virological failure in patients with genotype 1.

BACKGROUND: Current stopping rules during pegylated interferon (peg-IFN)/ribavirin (RBV) treatment rely on week 12 HCV RNA response, but earlier identification of non-responders offers clinical and economic advantages. AIMS AND METHODS: To evaluate, among 129 HCV-genotype-1-infected, treatment-naive patients receiving peg-IFN/RBV, the feasibility of predicting treatment failure using receiver operating characteristics (ROC) curves after measuring week 4 HCV RNA decreases, and to assess baseline predictors of not achieving sustained virological response (SVR). RESULTS: Peg-IFN-alpha2b was used in 84.5% of patients. Fifty-three (41%) reached SVR. The best cutoff value of HCV RNA decrease at week 4 to predict non-SVR corresponded to 1 log10 IU/ml: sensitivity and negative predictive value: 100%; specificity: 64%; positive predictive value: 66%; ROC curve area: 0.91 (95% confidence interval [CI]: 0.86-0.96). By applying this threshold, treatment could have been discontinued at week 4 in 64% of virological non-responders (49/76). By univariate analysis, baseline HCV RNA > 800,000 IU/ml (P = 0.029), older age (P = 0.011), and higher aspartate aminotransferase (AST) levels (P = 0.005) or AST/alanine aminotransferase ratio values (P = 0.04) were associated with failure. After multivariate analysis, only baseline HCV RNA >800,000 IU/ml (odds ratio [OR]: 2.12; 95% CI: 1.005-4.488; P = 0.048) and higher AST levels (OR: 1.01; 95% CI: 1.003-1.024; P = 0.011) remained statistically significant. CONCLUSIONS: The lack of > or = log10 IU/ml decrease in baseline HCV RNA at week 4 was 100% predictive of treatment failure, independently associated with HCV RNA > 800,000 IU/ml and higher AST levels.

Syncytial giant cell hepatitis in human immunodeficiency virus-infected patients with chronic hepatitis C: 2 cases and review of the literature.

Syncytial giant cell hepatitis (SGCH) among adult human immunodeficiency virus (HIV)-infected patients has been rarely described. Most cases have been reported in subjects coinfected with the hepatitis C virus (HCV), but its prevalence and outcome remain unknown. We performed a retrospective analysis of all cases of SGCH among 332 liver biopsies from HIV-infected patients seen at a tertiary center in Madrid, Spain, between 1984 and March 2004. Two hundred fifty specimens were obtained from HCV-coinfected patients. There were 2 cases of SGCH, leading to an observed overall prevalence of 0.6% (0.8% when considering only HCV-coinfected patients). In addition to histological changes secondary to chronic hepatitis C, the liver cords were replaced by syncytial giant cells with up to 30 nuclei. There was no histological evidence of measles (among paramyxoviruses) or herpes viruses group infections. In patient 1, there was a progressive clinical worsening after a 3-month course of prednisone, leading to liver failure and death. His postmortem liver biopsy showed more abundant giant hepatocytes accompanied with the development of a histologic pattern of severe fibrosing cholestatic hepatitis. The second patient received a prolonged course of pegylated interferon-alpha-2b and ribavirin with clearance of syncytial giant hepatocytes despite HCV-RNA persistence. SGCH is a rare histological finding among HIV-infected patients with chronic hepatitis C. Specific treatment with pegylated interferon and ribavirin can lead to histological resolution and biochemical improvement, even in the absence of HCV-RNA clearance.

Safe use of pegylated interferon/ribavirin in hepatitis C virus cirrhotic patients with hypersplenism after partial splenic embolization.

BACKGROUND AND AIMS: Partial splenic embolization (PSE) is a non-surgical alternative for the treatment of hypersplenism. Thrombocytopenia precludes the use of pegylated interferon (peg-IFN) and ribavirin in cirrhotic patients with hepatitis C virus (HCV). We aimed to evaluate the role of PSE as a procedure allowing combined HCV therapy in this setting. METHODS: A retrospective analysis of the safety and rate of sustained virological response (SVR) after a full-dose course of peg-IFN plus ribavirin in eight HCV cirrhotic patients with severe hypersplenism undergoing PSE at a tertiary centre in Madrid, Spain, from May 2002 to August 2004. RESULTS: Six patients (75%) were in Child-Pugh class B (median score 7). PSE significantly improved the mean platelet (P = 0.012), leucocyte (P = 0.017) and haemoglobin (P = 0.035) levels, and prothrombin activity (P = 0.012). After a mean of 20 weeks after PSE all patients started weight-adjusted ribavirin plus peg-IFN-alpha2b (n = 6) or 180 microg/week of peg-IFN-alpha2a (n = 2). Six subjects (75%) completed therapy with no peg-IFN dose reductions; the dose of ribavirin was reduced in two patients reaching haemoglobin levels of less than 10 g/dl (one also received erythropoietin and granulocyte colony-stimulating factor because of neutrophil counts < 300 cells/microl). Three patients (38%) achieved SVR. Portal vein thrombosis was observed in 50% of patients, but did not preclude antiviral therapy. The pathogenic mechanism was multifactorial. It was successfully managed with anticoagulant therapy in two cases. CONCLUSIONS: PSE allowed the safe use of peg-IFN plus ribavirin in HCV cirrhotic patients with severe cytopenias who otherwise would never have been treated. The rate of SVR was 38%.

Pegylated interferon alpha2b plus ribavirin for the treatment of chronic hepatitis C in HIV-infected patients.

BACKGROUND: Hepatitis C virus (HCV) and HIV coinfection constitutes an important epidemiological and clinical problem. We evaluated the safety and efficacy of Pegylated interferon alpha2b (Peg-IFN) and a fixed dose of ribavirin in the treatment of chronic hepatitis C in HIV coinfection. METHODS: Open, prospective study in HCV-HIV coinfected patients with persistently elevated alanine aminotransferase (ALT) levels and a liver biopsy showing either portal or bridging fibrosis. Therapy included Peg-IFN (50 micro g weekly) with ribavirin 800 mg for 48 weeks. The primary end point was sustained virological response (SVR). Univariate and multivariate analyses were performed to determine factors associated with response. RESULTS: By intent-to-treat analysis, 11 of 35 patients (31%) reached SVR. SVR was significantly better for genotypes 2/3 than for genotype 1 (54% versus 21%; P < 0.05). By multivariate logistic regression analysis, only a non-1 genotype was an independent factor for SVR [odds ratio (OR), 6; 95% confidence interval (CI), 1.1-31.7; P < 0.005]. A decrease of at least 1.5 log10 HCV RNA at week 12 of therapy was highly predictive of SVR (OR, 49.9; 95% CI, 4.9-508.2; P < 0.001). Most patients developed adverse events, although only six patients (17%) discontinued treatment due to toxicity. CONCLUSIONS: The combination of low doses of Peg-IFN plus a fixed dose of ribavirin resulted in a rate of SVR similar to that obtained with higher doses of the drugs in HIV-infected patients and lower than those obtained in non-HIV patients. Response at week 12 may be useful to help guide therapy in HCV-HIV co-infected patients.

Partial splenic embolization for the treatment of hypersplenism in cirrhotic HIV/HCV patients prior to pegylated interferon and ribavirin.

Partial splenic embolization (PSE), a non-surgical treatment for hypersplenism, has also been reported to improve hepatic function. As severe thrombocytopaenia or leukopaenia contraindicate the use of combined therapy with pegylated interferons (PEG-IFNs) and ribavirin (RBV) in HCV-related cirrhosis, we evaluated, from July 2002 to October 2003, the safety and effectiveness of PSE as a procedure to allow therapy for HCV in three Child-Pugh class B cirrhotic patients with hypersplenism and HIV co-infection. HCV genotypes were 1b (n=2) and 3a (n=1). Severe thrombocytopaenia (in all) and leukopaenia (in two) precluded therapy for HCV. PSE was successfully performed in all with a mean infarcted area of 80%, leading to a significant increase in platelet and leukocyte counts that allowed therapy with weight-adjusted RBV and PEG-IFN-alpha-2b (patients 1 and 3) or 180 microg of PEG-IFN-alpha-2a (patient 2) 8 weeks after the procedure. Moderate pain, well controlled with conservative measures, followed PSE in 100% of cases, but during follow-up (mean 422 days) there were no infectious complications or liver decompensation episodes. Although preliminary, these results suggest the potential role of PSE in HIV/HCV-cirrhotic subjects with hypersplenism as a procedure to allow the use of combined PEG-IFN and RBV.

Cherubism associated with neurofibromatosis type 1, and multiple osteolytic lesions of both femurs: a previously undescribed association of findings.

We present a patient with neurofibromatosis type 1, with the clinical, radiological and histological features of cherubism mandibular lesions, and multiple osteolytic, geographic lesions in both femurs, consistent with multiple non-ossifying fibromas. We have been unable to find a similar case in the world literature. We discuss our findings in relationship with a number of syndromes that present clinical, radiological or pathological similarities.

HCV clearance and treatment outcome in genotype 1 HCV-monoinfected, HIV-coinfected and liver transplanted patients on peg-IFN-alpha-2b/ribavirin.

BACKGROUND/AIMS: Differences in HCV-RNA clearance during therapy might explain the lower efficacy of peg-IFN/RBV in HIV/HCV-coinfection. There are limited data on HCV-RNA clearance and treatment outcomes in liver transplanted (LT) patients. METHODS: To assess the rates of SVR and baseline predictors of failure after 48 weeks of weight-adjusted peg-IFN-alpha-2b/RBV in 120 patients with HCV genotype 1: 61 HCV-monoinfected, 40 HIV-coinfected and 19 LT-patients. Viral clearance was evaluated in patients completing 24 weeks of therapy (n=112, 93%). RESULTS: SVR was significantly lower in HIV-coinfection than in HCV-monoinfection or LT (18 vs. 39 vs. 42%, P<0.02). By multivariate analysis, HIV-coinfection (OR 3.048, 95% CI 1.133-8.196; P=0.027), baseline HCV-RNA over 800,000 IU/ml (OR 2.800; 95% CI 1.121-6.993, P=0.027) and higher AST values (OR 1.009; 95% CI 1.001-1.018; P=0.028) were significantly associated to failure. Despite similar baseline HCV load (5.67 vs. 5.75 vs. 5.90 log10 IU/ml), HIV-coinfection showed significantly lower HCV-RNA decreases than HCV-monoinfection at weeks 4 (P=0.015), 12 (P=0.015) and 24 (P=0.0003), and than LT at weeks 12 (P=0.003) and 24 (P=0.023). 36/60 subjects (60%) reaching EVR by week 12 obtained SVR vs. 3/60 (5%) who did not. CONCLUSIONS: HIV-coinfection was independently associated to treatment failure, and led to a significantly slower HCV-RNA clearance.
