Guideline for the diagnosis, treatment and long-term management of cutaneous lupus erythematosus.

Cutaneous lupus erythematosus (CLE) is an inflammatory, autoimmune disease encompassing a broad spectrum of subtypes including acute, subacute, chronic and intermittent CLE. Among these, chronic CLE can be further classified into several subclasses of lupus erythematosus (LE) such as discoid LE, verrucous LE, LE profundus, chilblain LE and Blaschko linear LE. To provide all dermatologists and rheumatologists with a practical guideline for the diagnosis, treatment and long-term management of CLE, this evidence- and consensus-based guideline was developed following the checklist established by the international Reporting Items for Practice Guidelines in Healthcare (RIGHT) Working Group and was registered at the International Practice Guideline Registry Platform. With the joint efforts of the Asian Dermatological Association (ADA), the Asian Academy of Dermatology and Venereology (AADV) and the Lupus Erythematosus Research Center of Chinese Society of Dermatology (CSD), a total of 25 dermatologists, 7 rheumatologists, one research scientist on lupus and 2 methodologists, from 16 countries/regions in Asia, America and Europe, participated in the development of this guideline. All recommendations were agreed on by at least 80% of the 32 voting physicians. As a consensus, diagnosis of CLE is mainly based on the evaluation of clinical and histopathological manifestations, with an exclusion of SLE by assessment of systemic involvement. For localized CLE lesions, topical corticosteroids and topical calcineurin inhibitors are first-line treatment. For widespread or severe CLE lesions and (or) cases resistant to topical treatment, systemic treatment including antimalarials and (or) short-term corticosteroids can be added. Notably, antimalarials are the first-line systemic treatment for all types of CLE, and can also be used in pregnant patients and pediatric patients. Second-line choices include thalidomide, retinoids, dapsone and MTX, whereas MMF is third-line treatment. Finally, pulsed-dye laser or surgery can be added as fourth-line treatment for localized, refractory lesions of CCLE in cosmetically unacceptable areas, whereas belimumab may be used as fourth-line treatment for widespread CLE lesions in patients with active SLE, or recurrence of ACLE during tapering of corticosteroids. As for management of the disease, patient education and a long-term follow-up are necessary. Disease activity, damage of skin and other organs, quality of life, comorbidities and possible adverse events are suggested to be assessed in every follow-up visit, when appropriate.

High-efficiency, high-flux in-line hemofiltration using a high blood flow extracorporeal circuit.

The ability of current renal replacement therapy modalities to achieve rapid solute removal is limited by membrane surface area and blood flow rate. Extracorporeal membrane oxygenation offers high blood flow and hemodynamic support that may be harnessed to overcome limitations in traditional renal replacement therapy. Using an extracorporeal membrane oxygenation circuit, we describe a high blood flow, high-efficiency hemofiltration technique using in-line hemofilters (hemoconcentrators) and standard replacement fluid to enhance solute clearance. Using this approach and a total of 5 L of replacement volume per treatment, creatinine (Cr) clearances of 8.3 L/hour and 11.2 L/hour using one and two hemoconcentrators, respectively, were achieved. With use of a high blood flow rate of up to 5 L/min, this hemofiltration technique can potentially offer clearance of 30 times that of continuous renal replacement therapy and of 6 times that of hemodialysis which may expand the ability to remove substances traditionally not considered removable via existing extracorporeal therapies.

The Effect of Radium-223 Therapy in Agent Orange-Related Prostate Carcinoma.

BACKGROUND: Radium-223 (Ra-223) radioisotope has been reported to increase median survival in bone metastatic prostate carcinoma. The addition of Ra-223 to abiraterone was associated with an increased risk of bone fractures. There has been no comprehensive data for using Ra-223 in veterans who were exposed to Agent Orange (AO+). METHODS: We present a retrospective study of veterans with bone metastatic castration-resistant prostate cancer (CRPC) who received standard doses of Ra-223 and other sequential therapies at US Department of Veterans Affairs Pittsburgh Healthcare System in Pennsylvania from January 2014 to January 2019. Veterans were divided into 2 groups: those who were exposed to Agent Orange (AO+) and those who had no exposure (AO-). Time to study was calculated from the initiation of Ra-223. Time to skeletal-related events (SRE), progression of prostate specific antigen (PSA), bone metastasis, and alkaline phosphatase (ALP) were calculated in months using unpaired t test with 2-tailed P values. Median survival was calculated by Kaplan Meier R log-rank test. RESULTS: There were 34 veterans with bone metastatic CRPC: 17 veterans (50%) were AO+ and 17 veterans (50%) were AO-. The mean age of diagnosis of AO+ veterans was 62 years and 69 years (P = .005) for AO- veterans (the mean Gleason score 8.2 and 8.0, respectively [P = .71]). The median number of Ra-223 cycles was 6 (60%). Ten veterans received Ra-223 as first line (29%) and 24 veterans received Ra-223 later (71%). There were 12 SREs with median survival of 15 months. There was no difference in mean time to SRE between AO+ (8 veterans, 10.6 months) and AO- (4 veterans, 10.3 months) (P = .93). The mean time to PSA progression for AO+ was 5.4 months and AO- was 6.8 months (P = .28). Mean time to bone progression for AO+ was 7.6 months and AO- was 10.1 months (P = .16). Mean time to ALP progression for AO+ and AO- was 6.3 months and 8.7 months, respectively (P = .05). Twenty veterans (58%) had died. Median survival for Ra-223 first was 32 months and for Ra-223 later was 15 months (P = .14; hazard ratio [HR] 0.48; 95% CI, 0.17-1.3). Median survival for AO+ and AO- veterans was 12 months and 18 months, respectively (P = .15; HR, 2.0; 95% CI, 0.77-5.0). CONCLUSIONS: There was no statistical difference between AO+ and AO- veterans in terms of time to SRE, PSA, bone and ALP progression, even though there was a trend of shorter duration in AO+ veterans. There was no median survival difference between Ra-223 first vs Ra-223 later as well as between AO+ and AO- but there is a trend of worse survival in AO+ veterans.

A Case of Metastatic Adamantinoma That Responded Well to Sunitinib.

Adamantinoma is a rare low-grade malignant bone tumor of epithelial origin. Metastatic adamantinoma has been reported to be resistant to chemotherapy. We report a case of metastatic adamantinoma to the lung, 10 years after the initial diagnosis of tibial mass. The patient received radiation therapy to the lung with partial response. A surveillance PET scan revealed progression of the lung mass and biopsy confirmed to be progressive residual metastatic adamantinoma. He received carboplatin and etoposide for 7 months and achieved a partial response. Four months later, PET scan showed disease progression. We started him on sunitinib, a multikinase inhibitor. He achieved a good partial response for 3 years. He died due to pneumonia at the age of 72.

Modified Atkins diet in advanced malignancies - final results of a safety and feasibility trial within the Veterans Affairs Pittsburgh Healthcare System.

BACKGROUND: Dysfunctional mitochondrial processes limit malignant cells ability to use energy from fatty acids and ketones. Animal studies using ketogenic diets for cancer show encouraging results. We tested the diet's safety and feasibility in cancer patients across a broad variety of solid tumors. METHODS: We recruited 17 advanced cancer patients who were not on chemotherapy. They consumed 20 to 40 g of carbohydrates daily with evaluations performed weekly until week 4, then every 4 weeks until 16 weeks. Quality of life questionnaires monitored for tolerability and compliance. Positron emission/computerized tomography was ordered at baseline, 4,8 and 16 weeks. Student t-testing evaluated differences between baseline and last visit scores for quality of life, weight, body mass index, and serum parameters. Correlations between weight loss and serum ketones, glucose, lipids and creatinine were done. Two-tailed unpaired t-testing of the mean weight loss compared responders against non-responders. RESULTS: Eleven out of seventeen enrolled patients were evaluable. Mean age was 65+/- 11.7 years, weight 203 +/- 4.98 lbs. (92 ± 2.3 kgs.) and previous treatment failures was 1.7, +/- 0.97. All lost significant weight with hematologic, biochemical and lipid tests remaining stable. Quality of life scores slightly improved. At 4,8 and 16 weeks, six (54.5 %), five (45.4 %) and four (36 %) patients were stable or improved. We observed no correlations between serum glucose, ketones or lipids. Clinical response did not correlate with ketosis or glycemia. Responders (stable disease or partial responders) lost statistically more weight than non-responders. Dietary compliance was difficult. Only three patients continued dieting past 16 weeks. Out of these, two patients developed brain metastases and were on steroids. They survived 80 and 116 weeks respectively. The third patient underwent residual tumor resection and has no disease at 131 weeks. CONCLUSIONS: Modified Atkins diets are safe and feasible in advanced cancer. Quality of life was preserved. Patients who lost at least 10 % of their body weight responded the best. Steroid intake affected optimal ketone and glucose levels. Despite this, survival improved in some melanoma and lung cancer patients. Further studies are recommended. TRIAL REGISTRATION: Clinicaltrials.gov NCT01716468. Registered on September 18, 2012.

Correlation between computed tomography and bone single photon emission-computed tomography scintigraphy in patients with chronic rhinosinusitis.

BACKGROUND: Computed tomography (CT) has been the imaging study of choicefor evaluating chronic rhinosinusitis (CRS). 99mTc-MDP bone single photon emission-computed tomography (SPECT) has proven useful at identifying inflammation of bone and its use in CRS has been discussed recently. No studies, however, have documented the correlation between these two imaging modalities in CRS. METHODS: A retrospective analysis was performed of 30 patients with CRS who underwent CT and SPECT scan of the paranasal sinuses. Increased radiotracer uptake during SPECT scan was compared with CT findings graded on the Lund-Mackay score (LMS). The findings of the two imaging modalities were compared and evaluated for standard correlative statistics for diagnostic tests. RESULTS: SPECT imaging was abnormal in 25/30 patients, and CT was abnormal in 27/30 patients. Correlation between the two was highest for the ethmoid sinuses at 73.3%. SPECT had a high positive predictive value for mucosal inflammation on CT of 84.1%. Approximately 25% of individual sinuses with a positive SPECT in patients without prior surgery were not positive in corresponding sinuses onl CT. There was a positive correlation between the LMS and the number of SPECT positive sinuses within the same patient (r = 0.486; p = 0.006). CONCLUSION: 99mTc-MDP SPECT scan in patients with CRS is shown to be a useful indicator of bone involvement. The relatively high rate of bone involvement in the absence of mucosal inflammation as seen in this study warrants additional research and the potential need for different therapies than are currently available.
