Acute leg pain and weakness in pregnancy: A new diagnosis of myotonic dystrophy.

We present a unique case of a 44-year-old woman who presented at 29 weeks' gestation with proximal limb pain and elevated creatine kinase. This occurred in the background of premature cataracts, atrial fibrillation and abnormal liver function. Clinical, pathological and neurodiagnostic findings supported a diagnosis of myotonic dystrophy, confirmed by genetic testing which revealed dystrophia myotonica protein kinase gene expansion. Muscle biopsy found both recent necrotising and chronic myopathic processes. Following delivery, the mother's myalgia resolved and creatine kinase quickly declined. The fetus was diagnosed with congenital myotonic dystrophy. We review the impact of myotonic dystrophy on pregnancy and discuss potential explanations for this patient's clinical course. This case emphasises the importance of considering myotonic dystrophy as a differential diagnosis in the right clinical context and the need for pre-pregnancy assessment and genetic counselling in women with known myotonic dystrophy.

Patient-Oriented Research to Improve Internet-Delivered Cognitive Behavioural Therapy for People of Diverse Ethnocultural Groups in Routine Practice.

There has been limited research on improving Internet-delivered Cognitive Behavioural Therapy (ICBT) in routine online therapy clinics that serve people from diverse ethnocultural groups (PDEGs). This article describes a patient-oriented adaptation approach used to address this gap in research. A working group consisting of people with lived experience, community representatives, ICBT clinicians, managers, and researchers was formed. The working group examined archival feedback on ICBT from past patients who self-identified as being from diverse ethnocultural backgrounds (N = 278) and the results of interviews with current patients (N = 16), community representatives (N = 6), and clinicians (N = 3). The archival data and interviews revealed the majority of the patients reported being satisfied with and benefitting from ICBT. Suggestions for improvement were not related to the cognitive-behavioural model and techniques, but rather to making treatment materials more inclusive. Consequently, the ICBT adaptation focused on adding content related to cultural influences on mental health, addressing stigma, diversifying case stories, examples, and imagery, adding audiovisual introductions, and replacing English idioms with more descriptive language. Moreover, further training was offered to clinicians, and efforts were made to improve community outreach. This study demonstrates a process for using patient-oriented research to improve ICBT within routine care serving patients of diverse backgrounds.

The impact of antineutrophil cytoplasmic antibody-associated vasculitis on employment and work disability in an Australian population.

AIM: Although antineutrophil cytoplasmic antibody-associated vasculitis (AAV) most commonly affects older individuals, many patients develop the disease during their most productive working years. The aim of this study was to examine the effects of AAV on employment and work disability in a cohort of Australian patients of working age. METHODS: Patients attending a vasculitis clinic located in Melbourne, Australia, completed an employment questionnaire in addition to the Work Productivity and Activity Impairment Questionnaire: Specific Health Problem. RESULTS: The average age of the 47 respondents was 47.8 ± 11.9 years (range 22-63 years), with a median disease duration of 60 months (range 10.2-318.5 months). There were 68.1% who were currently employed, but 20.6% of respondents employed at the time of diagnosis were no longer working and 10.6% had experienced a significant reduction in work hours since their diagnosis. There were 12.7% who were dependent on the disability support pension. The rate of work disability was 23.4%. Many participants considered themselves work impaired (41.9%), with 10.1% having missed work in the previous week. Furthermore, 44.7% of respondents reported that their financial stability had been negatively impacted by their vasculitis diagnosis. Fatigue was commonly reported. Work disabled patients were significantly more likely to be obese and less likely to have completed a tertiary education. Work disabled patients tended to be older, myeloperoxidase-antineutrophil cytoplasmic antibody positive, and have renal involvement and lung involvement. CONCLUSION: A proportion of people living with AAV in Australia experience a decline in employment and an increase in work disability when living with this condition.

Complete recovery from COVID-19 of a kidney-pancreas transplant recipient: potential benefit from everolimus?

We present a kidney-pancreas transplant recipient who achieved complete recovery from COVID-19. A 45-year-old patient with T3 paraplegia underwent kidney-pancreas transplantation 18 years ago, followed by a subsequent kidney transplant 9 years ago, and presented with fever, hypoxia and hypotension after exposure to two confirmed cases of COVID-19. History of solid organ transplant, pre-existing renal impairment, asthma and an elevated D-dimer were identified as established risk factors for severe COVID-19. Supportive management was provided, baseline immunosuppression with everolimus was continued, and oral prednisolone was increased. A complete recovery was observed. Given the favourable outcome despite risk factors for severe COVID-19, we identify and review the potential mitigating roles of immunosuppression and mammalian target of rapamycin (mTOR) inhibitors in this disease. Further investigation is required to establish whether mTOR inhibitors could be used as therapeutic agents to treat COVID-19, or as alternative immunosuppression implemented early in the COVID-19 disease course.

Long-Term Graft and Patient Outcomes Following Kidney Transplantation in End-Stage Kidney Disease Secondary to Hyperoxaluria.

BACKGROUND: End-stage kidney disease secondary to hyperoxaluria presents a major challenge for transplant physicians given concern regarding disease recurrence. Few contemporary studies have reported long-term outcomes following transplantation in this population. METHODS: This study examined the outcomes of all adult patients with end-stage kidney disease secondary to hyperoxaluria who received a kidney or combined liver-kidney transplant in Australia and New Zealand between 1965 and 2015. Patients with hyperoxaluria were propensity score matched to control patients with reflux nephropathy. The primary outcome was graft survival. Secondary outcomes included graft function, acute rejection, and patient survival. RESULTS: Nineteen transplants performed in 16 patients with hyperoxaluria were matched to 57 transplants in patients with reflux nephropathy. Graft survival was inferior in patients with hyperoxaluria receiving a kidney transplant alone (subhazard ratio [SHR] = 3.83, 95% confidence interval [CI], 1.22-12.08, P = .02) but not in those receiving a combined liver-kidney transplant (SHR = 0.63, 95% CI, 0.08-5.21, P = .67). Graft failure risk was particularly high in patients with hyperoxaluria receiving a kidney transplant alone after more than 1 year of renal replacement therapy (SHR = 8.90, 95% CI, 2.35-33.76, P = .001). Posttransplant estimated glomerular filtration rate was lower in patients with hyperoxaluria (10.97 mL/min/1.73 m2, 95% CI, 0.53-21.42, P = .04). There was no difference between groups in the risk of acute rejection or death with a functioning graft. CONCLUSION: Compared to reflux nephropathy, hyperoxaluria was associated with inferior graft survival in patients receiving a kidney transplant alone. Long-term graft function was lower in patients with hyperoxaluria, but the risks of acute rejection and death were not different.

Venous thromboembolism in primary central nervous system lymphoma during frontline chemoimmunotherapy.

BACKGROUND: In primary central nervous system lymphoma (PCNSL), venous thromboembolism (VTE) can cause significant morbidity and hinder chemotherapy delivery. OBJECTIVES: To assess VTE incidence, timing and adequacy of inpatient and outpatient VTE prophylaxis in patients with PCNSL receiving chemoimmunotherapy with curative intent. PATIENTS/METHODS: We reviewed patients diagnosed with PCNSL between 1997 and 2018 who received methotrexate, procarbazine, and vincristine ± Rituximab. Patient demographics, VTE prophylaxis and incidence, adverse events of anticoagulation, and survival outcomes were collected. RESULTS: Fifty-one PCNSL patients were included (median 67 years [range, 32-87], 30 males [59%]). Thirteen patients (25%, 95% confidence interval [CI], 14-40) developed VTE at a median of 1.6 months from diagnosis (range, 0-4). Patients with Khorana Risk Score ≥2 were more likely to have VTE than those with a KRS < 2 (60% vs 15%; P = .01). Eighty-five percent had deviations from inpatient VTE prophylaxis guidelines, and outpatient prophylaxis was not routinely administered. Three patients required inferior vena cava filters. Hemorrhagic complications of anticoagulation included an intracranial hemorrhage from therapeutic anticoagulation and three cases of major bleeding from prophylactic anticoagulation. No patients died from VTE or its treatment. CONCLUSIONS: Patients with newly diagnosed PCNSL are at high risk of VTE. Further research is required into optimal VTE prophylaxis in PCNSL.
