Raynaud’s phenomenon and digital ischemia: a practical approach to risk stratification, diagnosis and management

Anti-PL-12 anti-synthetase syndrome manifesting with multiple digital ischemia: Case report & review of the literature

Key Clinical Message

Acute digital ischemia is a rare manifestation of anti-synthetase syndrome in the absence of Raynaud's phenomenon. A high index of suspicion may result in early diagnosis and better clinical outcomes.

Abstract

A 61-year-old male patient was admitted to the hospital for worsening arthralgias with morning stiffness lasting hours, as well as left sided headaches, and jaw pain while eating. He had significant weight loss and subjective fever at home. Multiple fingers and toes were noted to be ischemic. His laboratory workup was pertinent for significantly elevated inflammatory markers, and mild Creatinine kinase elevation. Chest imaging and later lung biopsy were notable for organizing pneumonia. Conventional angiogram showed evidence of significant digital disease without collaterals. Subsequent autoimmune screening tests with extended myositis-specific and myositis-associated panels revealed a strongly positive anti-PL-12 antibody and moderately positive anti- SSA-52KD IgG ab. After ruling out infectious etiologies and malignancy, anti-synthetase syndrome (ASyS) diagnosis was considered in the presence of ischemic digits, organizing pneumonia, polyarthralgia, constitutional symptoms, increased inflammatory markers and positive antibodies. The patient was treated with high dose prednisone and mycophenolate mofetil along with amlodipine and sildenafil for digital vasodilation. Acute digital ischemia may be the first manifestation of ASyS with ILD. A high index of suspicion is warranted for early diagnosis and better outcomes.

Distal periarterial sympathectomy surgery for chronic digital ischemia: A systematic review of the literature

Objective

This study assesses the efficacy of distal periarterial sympathectomy in treating chronic digital ischemia by evaluating clinical outcomes of surgery.

Methods

A systematic literature review of distal sympathectomy for chronic digital ischemia was conducted. Data extracted included study design, patient statistics, aetiology, follow-up duration, sympathectomy level, and surgical outcomes.

Results

21 studies were analysed, containing a total of 337 patients, 324 hands, and 398 digits. Patient age ranged from 23.2 to 56.6 years. Causes of ischemia included Scleroderma, Raynaud's disease, atherosclerosis/Buerger's disease, systemic lupus erythematosus/discoid lupus, undifferentiated rheumatic disorder/mixed connective tissue disease, CREST syndrome, trauma and unknown diagnoses. Common digital artery sympathectomy was mostly performed. Follow-up spanned 12-120 months.

Outcomes

Distal sympathectomy led to reduced pain in 94.7 % patients. Complete resolution of ulceration was seen in 73 % patients. Subsequent amputation was required in 28 % patients. Other complications were reported in 24.1 % patients.

Conclusions

This study indicates that distal periarterial sympathectomy may effectively treat chronic digital ischemia, offering pain relief and resolution of digital ulceration. However, risks of complications and amputation persist. Further research is required to inform patient selection and establish the optimal technique and extent of distal sympathectomy surgery, before it can be considered a valid treatment option.

Black Digits Matter: A Multispecialty Enigma

Introduction Digital ischemia is alike any other visceral ischemic event leading to severe tissue damage ultimately causing necrosis of the involved extremity. It's like a preview of the upcoming systemic disorder and can present itself in any specialty and hence everyone, be it a physician or a surgeon must be primed toward how to proceed with a case of digital ischemia. In this case series, we present six such cases that presented with digital ischemic events either as a sole presentation or were followed by other systemic manifestations that led to their evaluation and ultimately the etiology behind it. Material and method Patients visiting Rheumatology OPD with complaints suggestive of digital ischemia were included in this study. All patients underwent thorough history taking and clinical examination to establish the cause of digital ischemia. Patients with probable infective, trauma, cardiac, and drug-induced causes and malignancies were excluded. As per probable autoimmune causes, patients underwent evaluation via antinuclear antibodies by immunofluorescence (ANA by IF), antiphospholipid antibodies like lupus anticoagulant (LAC), anticardiolipin antibodies (AcL) and anti Beta2GP1 antibodies, extractable nuclear antigens (ENA) and in cases of suspected vasculitis doppler ultrasound and angiography.  Results Six patients were identified as cases primarily presenting with digital ischemia or with a prior history of digital ischemia. Two patients were of the pediatric age group, one 16-year-old male presenting with acute arthritis and a history of digital ischemia one year back, and the other was a 12-year-old female with blackening of the second toe in her left foot with a history of similar complaints in the left great toe for which she underwent amputation of that toe. Other four cases were of the adult age group, with two cases of scleroderma, one with systemic lupus erythematosus, and one with Takayasu arteritis. All of these patients primarily presented to departments other than rheumatology. Conclusion Digital ischemia is a pan-specialty problem with the etiologies spreading across a vast spectrum of rheumatological disorders, many of which may present to different specialties initially, later discovered to be part of the systemic manifestation of autoimmune diseases. Hence, it becomes imperative to have a rheumatological perspective in these cases of digital ischemia which all specialities should be aware of, and timely referral may prevent permanent loss of the digits and in some cases the entire limb.

Training the Next Generation of Rheumatologists: What Is the Best Way to Teach Fellows About Scleroderma?

Rheumatology is rich in educational opportunities, learning about a variety of diseases. Rheumatology subspecialty training is a time of unparalleled learning, and within the curriculum of a training program, the connective tissue diseases (CTDs) represent a unique challenge to the fellows. The challenge therein lies in the multisystem presentations they are faced with mastering. Scleroderma, as a rare and life-threatening CTD, remains one of the most difficult conditions to manage and treat. In this article, the authors focus on an approach to training the next generation of rheumatologists to take care of patients with scleroderma.

Gemcitabine-induced peripheral vascular disease and prolonged response in a patient with metastatic pancreatic adenocarcinoma: A case report

BACKGROUND

Gemcitabine is an antimetabolite used in the treatment of pancreatic cancer. One of the side effects of gemcitabine is vascular toxicity. Here, we report the case of a patient treated with gemcitabine who had peripheral vascular disease concomitant with a prolonged antitumor response.

CASE SUMMARY

A 75-year-old man was diagnosed with locally recurrent pancreatic cancer. Partial response was achieved after 9 mo of gemcitabine. At the same time, the patient reported peripheral vascular disease without necrosis. Chemotherapy was suspended, and after one month the Positron Emission Tomography (PET) scan showed locoregional tumor recurrence. Gemcitabine was resumed and partial response was obtained, but peripheral vascular disease occurred.

CONCLUSION

Our results suggest that the appearance of peripheral vascular disease may be related to a prolonged response to gemcitabine.

Adaptable Poly-Articulated Bionic Hands EnhanceBoth Performance and User's Perception in Bilateral Amputation: A Case Study

This article evaluates and compares the performance and perception of prosthetic devices based on different design principles, a traditional rigid gripper and an adaptable poly-articulated hand, in a pre- and post-training protocol with an individual with bilateral amputation. As a representative of the first class, we use commercial hands (Ottobock's MyoHand VariPlus Speed), which is a widely adopted model by prosthesis users worldwide. We compare these with two SoftHand Pro hands, which are experimental prototypes exhibiting 19 articulations actuated by one single motor, and are inspired by human hand motor control models. Results show that the individual with bilateral amputation, who was a non-expert myoelectric user, achieved better performance with adaptive poly-articulated hands. Furthermore, the acceptation, satisfaction and perceived functionality of the user were considerably higher for the SoftHand Pro. An observational analysis of the patient's behaviour by experienced therapists suggests that adaptable poly-articulated hands reduced compensatory movements and cognitive load. Using soft technologies may be especially advantageous for individuals with bilateral amputation, who present a very limited residual mobility and can largely benefit from the active use of their artificial arms in everyday life.

Managing connective tissue disease: how to select and facilitate successful transplantation

PURPOSE OF REVIEW

Lung transplant (LTx) evaluation and selection of candidates with connective tissue disease (CTD) remains controversial and varies between centers, and the optimal candidate selection is still controversial.

RECENT FINDINGS

Recent United States and European publications have reported reasonable short-term and long-term LTx outcomes in patients with CTD to other lung fibrosis patients without CTD. This article discusses the recently published International Society for Heart and Lung Transplantation (ISHLT) consensus document recommendations to evaluate and select CTD candidates, the importance of early referral, posttransplant management, and the involvement of a multidisciplinary team.

SUMMARY

Future standardized practices among centers adapting the 2021 ISHLT consensus recommendations to evaluate and select CTD candidates will allow risk stratification, determine the best candidates, and facilitate the most successful long-term LTx outcomes.

ISHLT consensus document on lung transplantation in patients with connective tissue disease: Part III: Pharmacology, medical and surgical management of post-transplant extrapulmonary conditions statements

Patients with connective tissues disease (CTD) are often on immunomodulatory agents before lung transplantation (LTx). Till now, there's no consensus on the safety of using these agents perioperative and post-transplant. The International Society for Heart and Lung Transplantation-supported consensus document on LTx in patients with CTD addresses the risk and contraindications of perioperative and post-transplant management of the biologic disease-modifying antirheumatic drugs (bDMARD), kinase inhibitor DMARD, and biologic agents used for LTx candidates with underlying CTD, and the recommendations and management of non-gastrointestinal extrapulmonary manifestations, and esophageal disorders by medical and surgical approaches for CTD transplant recipients.

Vasopressor-Induced Digital Ischemia

In patients who are critically ill and in circulatory shock, substantial dosages of vasopressors including norepinephrine and Neosynephrine are often required to sustain blood pressure. While these medications are necessary and can be lifesaving, they are often associated with several complications related to severe vasoconstrictions. One of these known but underreported side effects is digital ischemia (DI). DI refers to a decrease in digital perfusion. It is a rare and uncommon phenomenon that can lead to significant consequences and unfortunately can result in amputation of the digits. Herein, we report an unfortunate female with septic shock secondary to acute bowel ischemia who developed bilateral digital necrosis while on norepinephrine.

ISHLT consensus document on lung transplantation in patients with connective tissue disease: Part I: Epidemiology, assessment of extrapulmonary conditions, candidate evaluation, selection criteria, and pathology statements

Patients with connective tissue disease (CTD) and advanced lung disease are often considered suboptimal candidates for lung transplantation (LTx) due to their underlying medical complexity and potential surgical risk. There is substantial variability across LTx centers regarding the evaluation and listing of these patients. The International Society for Heart and Lung Transplantation-supported consensus document on lung transplantation in patients with CTD standardization aims to clarify definitions of each disease state included under the term CTD, to describe the extrapulmonary manifestations of each disease requiring consideration before transplantation, and to outline the absolute contraindications to transplantation allowing risk stratification during the evaluation and selection of candidates for LTx.

Ultrasound Detection of Calcinosis and Association With Ulnar Artery Occlusion in Patients With Systemic Sclerosis

OBJECTIVE

To investigate the ability of ultrasound (US) compared to radiographs to detect calcinosis in hands/wrists of patients with systemic sclerosis (SSc), and to assess US markers of pathologic perfusion.

METHODS

Patients with SSc were evaluated for calcinosis in the hands/wrists by radiograph and US. The presence or absence of calcinosis was recorded by patient, hand, and anatomic zone; sensitivity and specificity for calcinosis detection by US versus radiographs was determined. Bilateral US vascular measurements of ulnar artery occlusion (UAO) and finger pulp blood flow (FPBF) were obtained. For each hand, associations between markers of pathologic blood flow (UAO, FPBF, and a composite severity score of UAO and FPBF) and the presence of calcinosis were assessed using generalized estimating equations.

RESULTS

Of 43 patients with SSc (19 diffuse, 24 limited), 39.5% had calcinosis on radiographs compared to 30.2% on US. Sensitivity and specificity for US, respectively, were 61% and 95% by zone, 78% and 98% by hand, and 76% and 100% by patient. UAO was seen in 30% and 28% of left and right hands, respectively; FPBF was absent in ≥1 digit of the left and right hands in 49% and 44%, respectively. UAO was associated with radiograph-identified calcinosis by hand (odds ratio [OR] 8.08 [95% confidence interval (95% CI) 2.45-26.60], P < 0.001), whereas FPBF and the composite severity score were not significant. UAO was associated with calcinosis even in the absence of digital ulcers (OR 33.00 [95% CI 3.39-321.09], P = 0.003).

CONCLUSION

US was sensitive and highly specific in detecting calcinosis in SSc. UAO was strongly associated with radiograph-identified calcinosis.

Convolutional Neural Networks for Differential Diagnosis of Raynaud’s Phenomenon Based on Hands Thermal Patterns

Raynaud’s phenomenon (RP) is a microvessels’ disorder resulting in transient ischemia. It can be either primary or secondary to connective tissue diseases, such as systemic sclerosis. The differentiation between primary and secondary to systemic sclerosis is of paramount importance to set the proper therapeutic strategy. Thus far, thermal infrared imaging has been employed to accomplish this task by monitoring the finger temperature response to a controlled cold challenge. A completely automated methodology based on deep convolutional neural network is here introduced with the purpose of being able to differentiate systemic sclerosis from primary RP patients by relying uniquely on thermal images of the hands acquired at rest. The classification performance of such a method was compared to that of a three-dimensional convolutional neural network model implemented to classify thermal images of the hands recorded during rewarming from a cold challenge. No significant differences were found between the two procedures, thus ensuring the possibility to avoid the cold challenge. Moreover, the convolutional neural network models were compared with standard feature-based approaches and showed higher performances, thus overcoming the limitations related to the feature extraction (e.g., biases introduced by the operator). Such automated procedures can constitute promising tools for large scale screening of primary RP and secondary to systemic sclerosis in clinical practice.

Vascular Acrosyndromes Associated With Prolonged Tumor Response in Advanced Lung Cancer Patients During Treatment With Antimetabolites: A Report of Two Cases

Background

Pemetrexed and gemcitabine are both antimetabolites drugs approved in advanced non-small cell lung cancer (NSCLC). Their toxicity profile is well known. However, rare vascular side effects can occur such as vascular acrosyndromes and especially digital ischemia. The cause of this disfiguring and painful event is still controversial. Amputation is frequently required and has been described as a predictor of poor survival outcomes.

Case Presentation

This report presents two cases of vascular acrosyndrome in NSCLC patients during treatment with antimetabolites (pemetrexed and gemcitabine). Patients presented severe digital ischemia having required prostacyclin analog and chemotherapy discontinuation. In one case, symptoms improved while in the other case symptoms persisted. Both patients experienced prolonged tumor response. These findings suggest a multifactorial mechanism behind digital necrosis including an autoimmune process, which could lead to prolonged tumor control as described with immune checkpoint inhibitors.

Conclusion

Severe vascular acrosyndrome such as digital ischemia can occur in lung cancer patients treated with antimetabolites. Awareness needs to be raised when using these drugs in patients with predisposing factors. Whether occurrence of chemotherapy-induced immune vascular side effects might explain prolonged tumor response deserves further investigations.

Upper Extremity Angiographic Patterns in Systemic Sclerosis: Implications for Surgical Treatment

PURPOSE

Conventional angiography is often used in the preoperative work-up of hand surgery patients with systemic sclerosis. The goal of this study was to propose a classification system based on the pattern of arterial involvement in a series of upper extremity angiograms. The authors hypothesized that this classification system would demonstrate high inter- and intrarater reliability.

METHODS

A retrospective review of 110 upper extremity angiograms in patients with systemic sclerosis (obtained between 1996 and 2017) was performed. Images were classified into 4 types based on the patency of the radial and ulnar arteries at the wrist, and into 3 subtypes based on the patency of the superficial and deep palmar arches. Classification reliability was compared with Fleiss' Kappa (for inter-rater) and Cohen's (for intrarater) coefficient between 4 fellowship-trained hand surgeons and a hand fellow.

RESULTS

The inter-rater reliability between all 5 observers using types alone was 0.83 (0.80-0.85), whereas the inter-rater reliability using subtypes was 0.64 (confidence interval [CI] 95%, 0.62-0.65). The intrarater reliability using types alone ranged from 0.80 to 0.95, whereas intrarater reliabilities using subtypes were 0.81 (CI 95%, 0.72-0.90), 0.78 (CI 95%, 0.69-0.87), 0.87 (CI 95%, 0.80-0.95), 0.64 (CI 95%, 0.53-0.75), and 0.92 (CI 95%, 0.86-0.98) for the 4 attendings and a hand fellow, respectively. Fifty-seven percent of angiograms were interpreted as having loss of ulnar artery patency at the wrist (type 2) with 77% having additional loss of superficial palmar arch patency (type 2A).

CONCLUSIONS

This large series of angiograms in patients with systemic sclerosis demonstrates a classification system for conventional angiography that shows high inter-rater and intrarater reliability using type alone. When subtypes were used, the inter-rater and intrarater reliabilities decreased to moderate and moderate-to-high, respectively.

CLINICAL RELEVANCE

This study represents the first step in establishing a classification system that, by grouping patients with similar angiogram findings, may allow for targeted research into risk stratification, monitoring, and treatment in systemic sclerosis.

Paraneoplastic digital ischemia in clear-cell renal-cell carcinoma: Report of a case and review of the literature

Digital ischemia has been rarely associated, as a paraneoplastic syndrome, with renal cancer. Since it can severely compromise the patients' quality of life, early recognition is important, in order to optimally address it with currently available treatment options, such as tyrosine inhibitors. Digital ischemia may occur in the general population and it can be the result of other non-cancerous diseases; accordingly, a thorough and aggressive work-up is mandatory, together with appropriate therapeutic steps such as tyrosine kinase inhibitors, vasodilators, and antiaggregants. Herein, we report a 78-year-old male patient with a history of clear-cell renal-cell cancer, who presented in the emergency department with critical ischemia in the upper limbs.

Innovations in the Assessment of Primary and Secondary Raynaud's Phenomenon

Objectives: Raynaud's phenomenon (RP) is characterized by intense vasospasm of the digital arteries that causes characteristic color changes in fingers. There are two main types of RP: Primary RP (PRP) and Secondary RP (SRP). PRP is a benign condition. Whilst SRP is associated with several connective tissue diseases (CTD), in particular systemic sclerosis (SSc). The objectives of this report were: to present a short review on morphological (nailfold videocapillaroscopy, NVC) and functional techniques (laser tools and thermography) that allow for a correct diagnosis and treatment of RP and to investigate blood perfusion (BP) by laser speckle contrast analysis (LASCA) in different skin areas of hands and face in PRP, SRP to SSc, and healthy subjects (CNT). Methods: 31 PRP patients (LeRoy criteria), 70 SRP to SSc (ACR/EULAR criteria) and 68 CNT were enrolled. BP was assessed by LASCA at the level different areas of hands and face. NVC was performed to distinguish between PRP and SRP, and to detect the proper pattern of nailfold microangiopathy in SSc patients. Results: Both PRP and SRP showed a statistically significant lower BP than CNT at the level of fingertips (p < 0.0001), periungual (p < 0.0001), palmar aspect of 3rd finger (p < 0.0001), and palm areas (p < 0.0001). Moreover, BP was significantly lower in PRP than in SRP to SSc with the "Early" pattern of microangiopathy in the same areas as above (p < 0.04). Conclusion: By considering a small cohort of patients, BP of hands was found lower in PRP than in SSc patients with the "Early" NVC pattern of microangiopathy.

The effects of upper and lower limb exercise on the microvascular reactivity in limited cutaneous systemic sclerosis patients

BACKGROUND

Aerobic exercise in general and high-intensity interval training (HIIT) specifically is known to improve vascular function in a range of clinical conditions. HIIT in particular has demonstrated improvements in clinical outcomes, in conditions that have a strong macroangiopathic component. Nevertheless, the effect of HIIT on microcirculation in systemic sclerosis (SSc) patients is yet to be investigated. Therefore, the purpose of the study was to compare the effects of two HIIT protocols (cycle and arm cranking) on the microcirculation of the digital area in SSc patients.

METHODS

Thirty-four limited cutaneous SSc patients (65.3 ± 11.6 years old) were randomly allocated in three groups (cycling, arm cranking and control group). The exercise groups underwent a 12- week exercise program twice per week. All patients performed the baseline and post-exercise intervention measurements where physical fitness, functional ability, transcutaneous oxygen tension (ΔTcpO2), body composition and quality of life were assessed. Endothelial-dependent as well as -independent vasodilation were assessed in the middle and index fingers using LDF and incremental doses of acetylcholine (ACh) and sodium nitroprusside (SNP). Cutaneous flux data were expressed as cutaneous vascular conductance (CVC).

RESULTS

Peak oxygen uptake increased in both exercise groups (p < 0.01, d = 1.36). ΔTcpO2 demonstrated an increase in the arm-cranking group only, with a large effect, but not found statistically significant,(p = 0.59, d = 0.93). Endothelial-dependent vasodilation improvement was greater in the arm-cranking (p < 0.05, d = 1.07) in comparison to other groups. Both exercise groups improved life satisfaction (p < 0.001) as well as reduced discomfort and pain due to Raynaud's phenomenon (p < 0.05). Arm cranking seems to be the preferred mode of exercise for study participants as compared to cycling (p < 0.05). No changes were observed in the body composition or the functional ability in both exercise groups.

CONCLUSIONS

Our results suggest that arm cranking has the potential to improve the microvascular endothelial function in SSc patients. Also notably, our recommended training dose (e.g., a 12-week HIIT program, twice per week), appeared to be sufficient and tolerable for this population. Future research should focus on exploring the feasibility of a combined exercise such as aerobic and resistance training by assessing individual's experience and the quality of life in SSc patients.

Bilateral Brachial Artery Disease Presenting with Features of Raynaud's Phenomenon: A Case Report and Review of the Literature

Objective

To present a case of bilateral brachial artery disease presenting with features of Raynaud's phenomenon which was successfully treated with angioplasty and stenting, together with a review of the relevant literature.

Case

A 71-year-old female presented with a one-year history of intermittent pallor of both hands precipitated with cold objects. On examination, bilateral radial pulses were reduced. Prior photos showed pallor of the distal aspect of both palms. Angiogram showed high grade stenosis of the right brachial artery and focal occlusion with likely dissection of the left brachial artery. She underwent angioplasty and stenting for both lesions. She was asymptomatic without further episodes of Raynaud's phenomenon after five months on dual antiplatelet therapy. Upper-extremity vascular stenosis is uncommon. Structural changes in the vessel wall can cause vasospastic attacks, a mechanism described in secondary Raynaud's phenomenon. We hypothesize that these attacks may have been precipitated by the bilateral brachial artery disease. Furthermore, resolution of the symptoms after stent further supports our theory.

Conclusion

Bilateral brachial artery disease is uncommon. Physicians should consider this in patients presenting with Raynaud's phenomenon. Brachial artery stenosis and occlusion is a treatable disease with good symptomatic outcomes after angioplasty and stenting.

Difficulties in diagnosis and treatment of severe secondary Raynaud's phenomenon in a Cameroonian woman: a case report

Background

Raynaud’s phenomenon is a microvascular disorder that results in exaggerated vasoconstriction over vasodilatation secondary to an alteration in autonomic control. Though benign, it can result in severe ulceration and ultimately gangrene associated with disfiguration and permanent deformity. We present a case of severe secondary Raynaud’s phenomenon in a black-African patient from a resource-limited setting, with focus on the difficulties encountered in the diagnosis and treatment.

Case presentation

A 43-year-old female Cameroonian farmer with a 7-year history of episodic paresthesia in her fingers and toes (when exposed to cold) presented to our emergency department with severe pain, ulceration, and “darkening” of her fingertips over a period of 2 days. An examination revealed bilateral ulceration and dry gangrene of her fingers and toes, based on which a diagnosis of secondary Raynaud’s phenomenon due to a connective tissue disease was proposed. Results of paraclinical investigations were normal. Lifestyle modification along with a calcium channel blocker and phosphodiesterase type 5 inhibitor provided significant relief.

Conclusions

An early diagnosis and knowledge on appropriate treatment of Raynaud’s phenomenon is of vital importance to prevent permanent tissue damage and disability. Relying on biphasic color change for the diagnosis of Raynaud’s phenomenon in black Africans can be potentially misleading.

My approach to the treatment of scleroderma

Systemic sclerosis (scleroderma) is unique among the rheumatic diseases because it presents the challenge of managing a chronic multisystem autoimmune disease with a widespread obliterative vasculopathy of small arteries that is associated with varying degrees of tissue fibrosis. The hallmark of scleroderma is clinical heterogeneity with subsets that vary in the degree of disease expression, organ involvement, and ultimate prognosis. Thus, the term scleroderma is used to describe patients who have common manifestations that link them together, whereas a highly variable clinical course exists that spans from mild and subtle findings to aggressive, life-threatening multisystem disease. The physician needs to carefully characterize each patient to understand the specific manifestations and level of disease activity to decide appropriate treatment. This is particularly important in treating a patient with scleroderma because there is no treatment that has been proven to modify the overall disease course, although therapy that targets specific organ involvement early before irreversible damage occurs improves both quality of life and survival. This review describes our approach as defined by evidence, expert opinion, and our experience treating patients. Scleroderma is a multisystem disease with variable expression; thus, any treatment plan must be holistic, yet at the same time focus on the dominant organ disease. The goal of therapy is to improve quality of life by minimizing specific organ involvement and subsequent life-threatening disease. At the same time the many factors that alter daily function need to be addressed, including nutrition, pain, deconditioning, musculoskeletal disuse, comorbid conditions, and the emotional aspects of the disease, such as fear, depression, and the social withdrawal caused by disfigurement.

Systemic sclerosis--challenges for clinical practice

The management of patients with systemic sclerosis (SSc) can be challenging because disease-associated damage is often difficult to reverse and curative therapies are not yet available. Early identification and appropriate monitoring of patients with SSc is, therefore, critical so that active disease can be controlled and tissue damage prevented or delayed. However, early diagnosis of SSc is often difficult because the early clinical stages of the disease can be very similar to that of other autoimmune conditions. Screening for major organ manifestations of SSc, particularly interstitial lung disease, pulmonary hypertension, renal involvement and cardiac disease is a priority because involvement of these organs is associated with shorter life expectancies and early intervention might prevent disease progression. The prevention and management of digital ischaemia is also important as appropriate therapy often prevents substantial morbidity and functional loss. Treating gastrointestinal dysmotility can usually be managed using proton pump inhibitors and promotility agents, although in severe cases total parenteral nutrition is required. Calcinosis in patients with SSc is another common challenge that requires appropriate disease management and pain control. Each of these topics, which are relevant to both physicians and patients with SSc, are reviewed in further detail herein.
