David J. Tunnicliffe; Davinder Singh-Grewal; Siah Kim; Jonathan C. Craig; Allison Tong

Management of systemic lupus erythematosus (SLE) is complex and variability in practices exists. Guidelines have been developed to help improve the management of SLE patients, but there has been no formal evaluation of these guidelines. This study aims to compare the scope, quality, and consistency of clinical practice guidelines on the diagnosis, monitoring, and treatment of patients with SLE.

BACKGROUND Intravenous (IV) cyclophosphamide has been first-line treatment for inducing disease remission in lupus nephritis. The comparative efficacy and toxicity of newer agents such as mycophenolate mofetil (MMF) and calcineurin inhibitors are uncertain. STUDY DESIGN Network meta-analysis. SETTING & POPULATION Patients with proliferative lupus nephritis. SELECTION CRITERIA FOR STUDIES Randomized trials of immunosuppression to induce or maintain disease remission. INTERVENTIONS IV cyclophosphamide, oral cyclophosphamide, MMF, calcineurin inhibitor, plasma exchange, rituximab, or azathioprine, alone or in combination. OUTCOMES Complete remission, end-stage kidney disease, all-cause mortality, doubling of serum creatinine level, relapse, and adverse events. RESULTS 53 studies involving 4,222 participants were eligible. Induction and maintenance treatments were administered for 12 (IQR, 6-84) and 25 (IQR, 12-48) months, respectively. There was no evidence of different effects between therapies on all-cause mortality, doubling of serum creatinine level, or end-stage kidney disease. Compared to IV cyclophosphamide, the most effective treatments to induce remission in moderate- to high-quality evidence were combined MMF and calcineurin inhibitor therapy, calcineurin inhibitors, and MMF (ORs were 2.69 [95% CI, 1.74-4.16], 1.86 [95% CI, 1.05-3.30], and 1.54 [95% CI, 1.04-2.30], respectively). MMF was significantly less likely than IV cyclophosphamide to cause alopecia (OR, 0.21; 95% CI, 0.12-0.36), and MMF combined with calcineurin inhibitor therapy was less likely to cause ovarian failure (OR, 0.25; 95% CI, 0.07-0.93). Regimens generally had similar odds of major infection. MMF was the most effective strategy to maintain remission. LIMITATIONS Outcome definitions not standardized, short duration of follow-up, and possible confounding by previous or subsequent therapy. CONCLUSIONS Evidence for induction therapy for lupus nephritis is inconclusive based on treatment effects on all-cause mortality, doubling of serum creatinine level, and end-stage kidney disease. MMF, calcineurin inhibitors, or their combination were most effective for inducing remission compared to IV cyclophosphamide, while conferring similar or lower treatment toxicity. MMF was the most effective maintenance therapy.

Disease activity, organ damage, and treatment burden are often substantial in children and adolescents with systemic lupus erythematous (SLE), and the complex interplay among the developing child, parents, and peers makes effective management difficult. We aimed to describe the experiences and perspectives of adolescents and young adults diagnosed with juvenile‐onset SLE to inform strategies for improving treatment and health outcomes.

Autosomal dominant polycystic kidney disease (ADPKD) is the commonest inherited cause of renal failure in adults, and is due to loss-of-function mutations in either the PKD1 or PKD2 genes, which encode polycystin-1 and polycystin-2, respectively. These proteins have an essential role in maintaining the geometric structure of the distal collecting duct in the kidney in adult life, and their dysfunction predisposes to renal cyst formation. The typical renal phenotype of ADPKD is the insidious development of hundreds of renal cysts, which form in childhood and grow progressively through life, causing end-stage kidney failure in the fifth decade in about half affected by the mutation. Over the past 2 decades, major advances in genetics and disease pathogenesis have led to well-conducted randomized controlled trials, and observational studies that have resulted in an accumulation of evidence-based data, and raise hope that the lifetime risk of kidney failure due to ADPKD will be progressively curtailed during this century. This review will provide a contemporary summary of the current state of the field in disease pathogenesis and therapeutics, and also briefly highlights the importance of clinical practice guidelines, patient perspectives, patient-reported outcomes, uniform trial reporting, and health-economics in ADPKD.

Objective. Managing juvenile-onset systemic lupus erythematosus (SLE) is particularly challenging. The disease may be severe, adolescent patients have complex medical and psychosocial needs, and patients must navigate the transition to adult services. To inform patient-centered care, we aimed to identify the healthcare and research priorities of young patients with SLE and describe the reasons underpinning their priorities. Methods. Face-to-face, semistructured interviews and focus groups were conducted with patients with SLE, aged from 14 to 26 years, from 5 centers in Australia. For each of the 5 allocation exercises, participants allocated 10 votes to (1) research topics; research questions on (2) medical management, (3) prevention and diagnosis, (4) lifestyle and psychosocial; and (5) healthcare specialties, and discussed the reasons for their choices. Descriptive statistics were calculated for votes and qualitative data were analyzed thematically. Results. The 26 participants prioritized research that alleviated the psychological burden of SLE. They allocated their votes toward medical and mental health specialties in the management of SLE, while fewer votes were given to physiotherapy/occupational therapy and dietetics. The following 7 themes underpinned the participants’ priorities: improving service shortfalls, strengthening well-being, ensuring cost efficiency, minimizing family/community burden, severity of comorbidity or complications, reducing lifestyle disruption, and fulfilling future goals. Conclusion. Young patients with SLE value comprehensive care with greater coordination among specialties. They prioritized research focused on alleviating poor psychological outcomes. The healthcare and research agenda for patients with SLE should include everyone involved, to ensure that the agenda aligns with patient priorities, needs, and values.

Judy Savige; A. Mallett; David J. Tunnicliffe; Gopala K. Rangan

a. We recommend screening for polycystic liver disease in all patients diagnosed with autosomal dominant polycystic kidney disease using abdominal ultrasound (1C). b. We recommend that all female patients with autosomal dominant polycystic kidney disease and liver cysts undergo counseling regarding the risks of pregnancy and exogenous estrogen exposure in worsening liver cyst growth (1C). c. We recommend that females at risk of symptoms from hepatic cysts avoid estrogen supplements (1D). d. We recommend that a multidisciplinary team (hepatologist, hepatobiliary surgeon, interventional radiologist, and nephrologist) care for patients with severe polycystic liver disease associated with autosomal dominant polycystic kidney disease (1D).

Objective. Systemic sclerosis (SSc) is a chronic, progressive autoimmune disease with major end-organ involvement. Much attention has been focused on the management of physical and clinical manifestations; however, the effect of the disease and treatment on the patient’s identity, relationships, functioning, and mental well-being are less known. We aimed to describe the patients’ perspectives and experiences of living with SSc. Methods. Electronic databases were searched to October 2014. Thematic synthesis was used to analyze the findings. Results. We included 26 studies involving 463 patients. Six key themes were identified: distressing appearance transformation (disturbing facial changes, stigmatizing sickness, unrecognizable self), palpable physical limitations (bodily restrictions, frustrating mind-body disconnect, pervasive fatigue, disabling pain), social impairment (breaking intimacy, struggling to fulfill family responsibilities, maintaining work, losing independence), navigating uncertainty (diagnostic ambiguity, medically fending for oneself, unpredictable course of illness), alone and misunderstood (fearful avoidance of fellow patients, invisible suffering), and gradual acceptance and relative optimism (adapting to change and accepting limitations, taking a positive spin, cautious hoping, empowering relationships, valuing medical support). Conclusion. SSc is a rare and unpredictable illness that undermines patients’ sense of certainty and control and impairs their self-image, identity, and daily functioning. Patient-centered care that encompasses strategies to promote self-esteem, resilience, and self-efficacy may help to improve treatment satisfaction and health and quality of life outcomes for patients with SSc.
