Impact of safety-related dose reductions or discontinuations on sustained virologic response in HCV-infected patients: Results from the GUARD-C Cohort

BACKGROUND: Despite the introduction of direct-acting antiviral agents for chronic hepatitis C virus (HCV) infection, peginterferon alfa/ribavirin remains relevant in many resource-constrained settings. The non-randomized GUARD-C cohort investigated baseline predictors of safety-related dose reductions or discontinuations (sr-RD) and their impact on sustained virologic response (SVR) in patients receiving peginterferon alfa/ribavirin in routine practice. METHODS: A total of 3181 HCV-mono-infected treatment-naive patients were assigned to 24 or 48 weeks of peginterferon alfa/ribavirin by their physician. Patients were categorized by time-to-first sr-RD (Week 4/12). Detailed analyses of the impact of sr-RD on SVR24 (HCV RNA <50 IU/mL) were conducted in 951 Caucasian, noncirrhotic genotype (G)1 patients assigned to peginterferon alfa-2a/ribavirin for 48 weeks. The probability of SVR24 was identified by a baseline scoring system (range: 0-9 points) on which scores of 5 to 9 and <5 represent high and low probability of SVR24, respectively. RESULTS: SVR24 rates were 46.1% (754/1634), 77.1% (279/362), 68.0% (514/756), and 51.3% (203/396), respectively, in G1, 2, 3, and 4 patients. Overall, 16.9% and 21.8% patients experienced 651 sr-RD for peginterferon alfa and ribavirin, respectively. Among Caucasian noncirrhotic G1 patients: female sex, lower body mass index, pre-existing cardiovascular/pulmonary disease, and low hematological indices were prognostic factors of sr-RD; SVR24 was lower in patients with 651 vs. no sr-RD by Week 4 (37.9% vs. 54.4%; P = 0.0046) and Week 12 (41.7% vs. 55.3%; P = 0.0016); sr-RD by Week 4/12 significantly reduced SVR24 in patients with scores <5 but not 655. CONCLUSIONS: In conclusion, sr-RD to peginterferon alfa-2a/ribavirin significantly impacts on SVR24 rates in treatment-naive G1 noncirrhotic Caucasian patients. Baseline characteristics can help select patients with a high probability of SVR24 and a low probability of sr-RD with peginterferon alfa-2a/ribavirin

Infected pancreatic necrosis: outcomes and clinical predictors of mortality. A post hoc analysis of the MANCTRA-1 international study

: The identification of high-risk patients in the early stages of infected pancreatic necrosis (IPN) is critical, because it could help the clinicians to adopt more effective management strategies. We conducted a post hoc analysis of the MANCTRA-1 international study to assess the association between clinical risk factors and mortality among adult patients with IPN. Univariable and multivariable logistic regression models were used to identify prognostic factors of mortality. We identified 247 consecutive patients with IPN hospitalised between January 2019 and December 2020. History of uncontrolled arterial hypertension (p = 0.032; 95% CI 1.135-15.882; aOR 4.245), qSOFA (p = 0.005; 95% CI 1.359-5.879; aOR 2.828), renal failure (p = 0.022; 95% CI 1.138-5.442; aOR 2.489), and haemodynamic failure (p = 0.018; 95% CI 1.184-5.978; aOR 2.661), were identified as independent predictors of mortality in IPN patients. Cholangitis (p = 0.003; 95% CI 1.598-9.930; aOR 3.983), abdominal compartment syndrome (p = 0.032; 95% CI 1.090-6.967; aOR 2.735), and gastrointestinal/intra-abdominal bleeding (p = 0.009; 95% CI 1.286-5.712; aOR 2.710) were independently associated with the risk of mortality. Upfront open surgical necrosectomy was strongly associated with the risk of mortality (p &lt; 0.001; 95% CI 1.912-7.442; aOR 3.772), whereas endoscopic drainage of pancreatic necrosis (p = 0.018; 95% CI 0.138-0.834; aOR 0.339) and enteral nutrition (p = 0.003; 95% CI 0.143-0.716; aOR 0.320) were found as protective factors. Organ failure, acute cholangitis, and upfront open surgical necrosectomy were the most significant predictors of mortality. Our study confirmed that, even in a subgroup of particularly ill patients such as those with IPN, upfront open surgery should be avoided as much as possible.

Clinical efficacy and safety of certolizumab pegol in cutaneous symptoms on psoriasis in patients with psoriatic arthritis: A retrospective analysis in real life

We present the results on retrospective analysis about the efficacy of Certolizumab pegol (CZP), an antitumor necrosis factor-alpha agent, as monotherapy on skin psoriasis (PsO) in patients affect both by psoriatic arthritis (PsA) and mild-severe PsO. To date, the CZP is authorized for the treatment of PsA, PsO beyond that rheumatoid arthritis, axial spondyloarthritis/ankylosing spondylitis, and Crohn's. Assessments included an evaluation of the Psoriasis Area and Severity Index (PASI). Twelve patients (9M and 3F mean age 57.8 +/- 8 years) were enrolled in our study. Nine patients had been previously treated with others biologic agents, three patients were naive. Clinical and laboratory evaluations including PASI, erythrosedimentation rate, and C-reactive protein were performed at baseline (BL), at Week 12 (W12), Week 24 (W24), and Week 52 (W52) of treatment. Although the combination between methotrexate and CZP is allowed, we included, in our study, patients treated only with CZP. In such a way as to be as specific as possible, topical corticosteroids, vitamin D derivatives, retinoid creams, anthralin derivatives as well as p-UVA or UV-B have been forbidden to enrolled patients. With the same purpose, all the patients used the identical moisturizing cream two times a day. Mean PASI score decreased from 18 (BL) to 0 (W52) as follows: 18 at BL, 4 at W12, 0 at W24, and 0 at W52. Severe adverse events were not reported. Safety evaluations were performed every 3 months: liver and renal functions were monitored in all patients during the treatment, and no patient presented abnormal values. To the best of our knowledge, this is the first report that highlights the efficacy of CZP as monotherapy in psoriasis with mild to severe cutaneous involvement. Although to date the drug is authorized only for PsA, our results demonstrate that CZP is safe and effective on both cutaneous and joint components representing, therefore, an effective option in the treatment of cutaneous symptoms of PsO. Limitations of our study are presented by the relatively short observation time (W52) and by numeric small study group. Long-term data with a larger number of enrolled patients are necessary in order to confirm our preliminary observations

Efficacy of Vismodegib in pigmented basal cell carcinoma: Appearances are deceiving

Basal cell carcinoma (BCC) is the most common skin cancer in humans. Pigmented basal cell carcinoma (pBCC) is a rare variant of BCC. Vismodegib, was the first drug to be approved for the treatment of locally advanced (laBCCs) or metastatic basal cell carcinoma. The aim of this study was to evaluate the efficacy of Vismodegib in patients with pBCCs. We retrospectively analyzed patients receiving Vismodegib as treatment for laBCCs presenting also various pBCCs. After 6 months of treatment, we performed excisional biopsies of pBCCs, that apparently at clinical and dermoscopic assessment did not respond to therapy. A total of nine patients were assessed. After 6 months of treatment, locally advanced target BCCs showed complete remission in four out of nine patients (44.4%), four patients (44.4%) were considered in partial remission and one patient (11%) showed no response to treatment. On the contrary, all the pBCCs showed both clinically and dermoscopically resistance to treatment. Therefore, clinically persistent pBCCs were surgically removed in three patients. Histology showed a complete elimination of the neoplastic cells together with features of previous regression. Our findings indicate that the efficacy of Vismodegib is higher than that documented by clinical or even dermatoscopic observation alone

Reflectance Confocal Microscopy Applied to Linear (en Coup de Sabre) Morphea

En coup de sabre morphea is a clinical variant of morphea, presenting as a linear depressed, atrophic area in the paramedian forehead or the frontoparietal scalp, resembling a stroke from a sword. It affects the skin and subcutaneous connective tissues, with possible extension to the underlying musculature, cartilage, and bone and variable association with neurologic symptoms. A 50-year-old woman presented to our clinic for evaluation of an atrophic lesion on her forehead and scalp appearing 1 year before, progressively extending over time. An alopecic atrophic area involving the skin and subcutaneous tissues of her right forehead and scalp arranged in a linear fashion with an "en coup de sabre" appearance was observed in relation with hair loss in the affected area. Reflectance confocal microscopy showed marked hyperreflective areas with severe eccrine gland atrophy. All sebaceous glands had disappeared, with sporadic follicular persistence reduction. Histopathological examination of a punch biopsy specimen taken from a central parietal alopecic area was consistent with a diagnosis of morphea. To our knowledge, this is the first report regarding the use of reflectance confocal microscopy as an ancillary diagnostic technique in linear localized morphea of the scalp and face. This noninvasive technique may represent a useful tool in distinguishing between early stages of the disease, with prevalence of inflammatory lymphocytic infiltrate, and late stages characterized by more prominent sclerosis with mild or absent signs of inflammation
