Cryoglobulinemic vasculitis and skin ulcers. Our therapeutic strategy and review of the literature

Objective: Cryoglobulinemic vasculitis (CV) involving small- and medium-sized vessels is very frequently associated with hepatitis C virus and may be responsible for multiple organ involvement and skin ulcers (SU). Skin ulcers are often non-healing cutaneous lesions, possibly complicated by local infection and gangrene; they may severely affect the patients[U+05F3] quality of life and the overall prognosis. Therefore, the treatment of cryoglobulinemic SU is particularly challenging in the clinical practice.The present work evaluated the prevalence and correlations of cryoglobulinemic SU with other clinico-epidemiological features of CV; moreover, our long-term experience with the management strategies of these cutaneous lesions was compared with the world literature on this topic. Methods: The study included 126 CV patients (24 male and 102 female, aged 69 ± 11.2 SD years, disease duration 7 ± 6.9 SD years), followed at our Rheumatology Unit during the past decade. All patients were carefully evaluated regarding the entire cryoglobulinemic syndrome with particular concern for clinical characteristics and treatment of SU. Results: Among 126 CV patients, 36 individuals (29%) experienced at least one episode of SU, more commonly localized at the lower limbs. Patients with complicating SU showed significantly higher percentage of purpuric manifestations (p < 0.01) and liver (p < 0.001), peripheral nerve (p < 0.02), and/or thyroid involvement (p = 0.019).Therapeutic approach to SU included both systemic (immunosuppressors, corticosteroids, and/or plasma exchange) and local treatments. Local treatments consisted of sharp or surgical debridement as well as interactive dressing according to the condition of wound bed, perilesional skin, and the possible presence of infection, detected in 29 of 36 (81%) individuals in our Rheumatology unit. All patients underwent analgesic treatment for SU-related background pain as well as procedural pain, which was critical for an effective local SU management.The large majority of patients with SU healed at a variable time interval according to the severity of the single lesion; only five patients with very severe, non-healing SU needed amputation.The updated review of the literature revealed the presence of SU in around a quarter of CV patients. Among systemic treatments, the anti-CD20 monoclonal antibody rituximab represents one of the most effective and frequently employed therapies; however, the available data focusing on local therapeutic approach are generally limited to anecdotal observations. Conclusions: Overall, the treatment of cryoglobulinemic SU should be tailored to the single patient[U+05F3]s conditions using combined systemic and local treatments; lesional sharp debridement and interactive dressing as well as procedural pain management were decisive, particularly for more severe, non-healing cutaneous lesions

From Localized Scleroderma to Systemic Sclerosis: Coexistence or Possible Evolution

Background. Systemic sclerosis (SSc) and localized scleroderma (LoS) are two different diseases that may share some features. We evaluated the relationship between SSc and LoS in our case series of SSc patients. Methods. We analysed the clinical records of 330 SSc patients, in order to find the eventual occurrence of both the two diseases. Results. Eight (2.4%) female patients presented both the two diagnoses in their clinical histories. Six developed LoS prior to SSc; in 4/6 cases, the presence of autoantibodies was observed before SSc diagnosis. Overall, the median time interval between LoS and SSc diagnosis was 18 (range 0–156) months. Conclusions. LoS and SSc are two distinct clinical entities that may coexist. Moreover, as anecdotally reported in pediatric populations, we suggested the possible development of SSc in adult patients with LoS, particularly in presence of Raynaud’s phenomenon or antinuclear antibodies before the SSc onset

Rituximab in the treatment of patients with systemic sclerosis. Our experience and review of the literature

BACKGROUND: The treatment of systemic sclerosis (SSc) represents a great clinical challenge because of the complex disease pathogenesis including vascular, fibrotic, and immune T- and B-lymphocyte-mediated alterations. Therefore, SSc should be treated by combined or sequential therapies according to prevalent clinico-pathogenetic phenotypes. Some preliminary data suggest that rituximab (RTX) may downregulate the B-cell over expression and correlated immunological abnormalities. METHODS: Here, we describe a series of 10 SSc patients (4M and 6F, mean age 46±13.5SD years, mean disease duration 6.3±2.7SD years; 5 pts had limited and 5 diffuse SSc cutaneous subset) treated with one or more cycles of RTX (4 weekly infusions of 375mg/m(2)). The main indications to RTX were interstitial lung fibrosis, cutaneous, and/or articular manifestations unresponsive to previous therapies; ongoing treatments remained unchanged in all cases. The effects of RTX were evaluated after 6months of the first cycle and at the end of long-term follow-up period (37±21SD months, range 18-72months). An updated review of the world literature was also done. RESULTS: RTX significantly improved the extent of skin sclerosis in patients with diffuse SSc at 6months evaluation (modified Rodnan skin score from 25±4.3 to 17.2±4.6; p=.022). A clinical improvement of other cutaneous manifestations, namely hypermelanosis (7/7), pruritus (6/8), and calcinosis (3/6) was observed. Moreover, arthritis revealed particularly responsive to RTX showing a clear-cut reduction of swollen and tender joints in 7/8 patients; while lung fibrosis detected in 8/10 remained stable in 6/8 and worsened in 2/8 at the end of follow-up. Pro-inflammatory cytokines, namely IL6, IL15, IL17, and IL23, evaluated in 3 patients with diffuse cutaneous SSc, showed a more or less pronounced reduction after the first RTX cycle. These observations are in keeping with the majority of previous studies including 6 single case reports and 10 SSc series (from 5 to 43 pts), which frequently reported the beneficial effects of RTX on some SSc manifestations, particularly cutaneous sclerosis, along with the improvement/stabilization of lung fibrosis. Possible discrepancies among different clinical studies can be related to the etiopathogenetic complexity of SSc and not secondarily to the patients' selection and disease duration at the time of the study. CONCLUSION: The present study and previous clinical trials suggest a possible therapeutical role of RTX in SSc, along with its good safety profile. The specific activity of RTX on B-cell-driven autoimmunity might explain its beneficial effects on some particular SSc clinical symptoms, namely the improvement of skin and articular involvement, and possibly the attenuation of lung fibrosis

Beyond cat scratch disease: a case report of bartonella infection mimicking vasculitic disorder

Cat scratch disease (CSD) is a bacterial disease caused by Bartonella henselae and it is mainly characterized by self-limiting lymphadenopathy in the draining site of a cat scratch or bite. We report a patient with history of fever, swelling lymph nodes, vasculitic-like skin lesions, and positivity of Bartonella serology initially considered as expression of a disimmune disease

Use of Neem oil and Hypericum perforatum for treatment of calcinosis-related skin ulcers in systemic sclerosis.

Objective This study evaluated Neem oil and Hypericum perforatum (Holoil®) for treatment of scleroderma skin ulcers related to calcinosis (SU-calc). Procedure: We retrospectively analyzed 21 consecutive systemic sclerosis (SSc) patients with a total of 33 SU-calcs treated daily with Holoil® cream compared with a control group of 20 patients with 26 SU-calcs. Holoil® was directly applied to skin lesions, while the control group received only standard medication. Results Application of Holoil® either resulted in crushing and complete resolution of calcium deposits or facilitated sharp excision of calcinosis during wound care sessions in 27/33 cases (81.8%). Complete healing of SU-calc occurred in 15/33 (45%) of cases within a time period of 40.1 ± 16.3 (mean ± SD) days, while 18/33 (55%) of lesions improved in terms of size, erythema, fibrin and calcium deposits. Patients reported a reduction of pain (mean numeric rating scale 7.3 ± 1.9 at baseline versus 2.9 ± 1.4 at follow-up) The control group had longer healing times and a higher percentage of infections. Conclusions The efficacy of local treatment with neem oil and Hypericum perforatum suggest that Holoil® could be a promising tool in the management of SSc SU-calc

One-year clinical experience on the use of Nintedanib in Systemic Sclerosis

AIM- Systemic Sclerosis (SSc) is a complex autoimmune disease characterized by vascular damage, immune activation and fibrosis of the skin and internal organs. Interstitial lung disease (ILD) is one of the most common causes of death. In 2019 Nintedanib was approved for SSc-related ILD, due to randomized clinical trials (RCTs) demonstrating a reduction in the annual rate of decline in Forced Vital Capacity (FVC). METHODS We reviewed eleven patients with SSc-related ILD from January 2020 to January 2021 and who started Nintedanib 150 mg twice a day. RESULTS- Non-Specific Interstitial Pneumonia (NSIP) was the most frequent HRCT pattern, followed by Usual Interstitial Pneumonia (UIP) and UIP/NSIP pattern. The mean of Modified Rodnan Skin Score (mRSS) at baseline was 9.23 (±10SD) points without any significant improvement during the follow-up. Patients continued their ongoing therapy for lung involvement. Mean FVC was 2233.6 ml [+/- 1066 ml] (61.3% predicted) at beginning and remained stable during the follow-up period. The mean modified British Council Medical Questionnaire (mmRC) decreased from 3 at baseline to 2.5 at the end of follow up and the mean of the Borg scale of dyspnea ameliorated from 7.27 at baseline to 6 at twelve months. Both the differences were not significant. Two patients stop therapy: one for partial intestinal obstruction and one for incoercible diarrhea. CONCLUSION- Nintedanib was generally well tolerated and we did not record any serious adverse even
