There are no screening recommendations for patients unless they have Barrett's esophagitis or a significant family history of this disease. Often, esophageal cancer is not diagnosed until patients present with dysphagia, odynophagia, anemia or weight loss. When symptoms occur, the stage is often stage Ⅲ or greater. Treatment of patients with very early stage disease is fairly straight forward using only local treatment with surgical resection or endoscopic mucosal resection. The treatment of patients who have locally advanced esophageal cancer is more complex and controversial. Despite multiple trials, treatment recommendations are still unclear due to conflicting data. Sadly, much of our data is difficult to interpret due to many of the trials done have included very heterogeneous groups of patients both histologically as well as anatomically. Additionally, studies have been underpowered or stopped early due to poor accrual. In the United States, concurrent chemoradiotherapy prior to surgical resection has been accepted by many as standard of care in the locally advanced patient. Patients who have metastatic disease are treated palliatively. The aim of this article is to describe the multidisciplinary approach used by an established team at a single high volume center for esophageal cancer, and to review the literature which guides our treatment recommendations.

Cysteamine is an essential component of treatment. There is solid evidence that cystine accumulation itself is not responsible for all abnormalities in cystinosis; there is also a deficiency of glutathione in the cytosol. Patients with cystinosis can be more susceptible to oxidative stress. Case-Diagnosis/Treatment The patient cohort comprised 23 cystinosis patients (16 males) aged <18 years (mean age 8.0± 3.6 years) with chronic kidney disease class I-IV with good adherence to treatment, including cysteamine. Oxidative stress was evaluated based on the levels of serum thiobarbituric acid-reactive substances (TBARS), and renal function was evaluated based on serum creatinine and cystatin C levels and creatinine clearance (Schwartz formula). N-Acetylcysteine (NAC), an antioxidant drug was given to all patients for 3 months (T1) at 25 mg/kg/day divided in three doses per day. The measured values at just before the initiation of NAC treatment (T0) served as the control for each patient. Results Median serum TBARS levels at T0 and T1 were 6.92 (range 3.3-29.0) and 1.7 (0.6-7.2) nmol/mL, respectively (p <0.0001). In terms of renal function at T0 and T1, serum creatinine levels (1.1±0.5 vs. 0.9±0.5 mg/dL, respectively; p <0.0001), creatinine clearance (69.7±32.2 vs. T1 = 78.5± 33.9 mL/min/1.73 m 2 , respectively; p =0.006), and cystatin c level (1.33 ± 0.53 vs. 1.15 ± 0.54 mg/l, respectively; p =0.0057) were all significantly different at these two time points. Serum creatinine measurements at 6 (T −6) and 3 months (T −3) before NAC initiation and at 3 (T +3) and 6 months (T +6) after NAC had been withdrawn were also evaluated. Conclusion During the 3-month period that our 23 cystinosis patients were treated with NAC, oxidative stress was reduced and renal function significantly improved. No side-effects were detected. Larger and controlled studies are needed to confirm these findings.

Method: Patients were diagnosed according to clinical and laboratory data. Treatment protocol was potassium supplementation, sodium, spironolactone, and non-steroidal anti-inflammatory drug. Patients who developed proteinuria were converted to angiotensin conversion enzyme inhibitor. The variables evaluated for each drug were Z-score for weight and stature, proteinuria, creatinine clearance, gastrointestinal complaints, amount of potassium supplementation, serum potassium and bicarbonate levels, and findings of upper digestive endoscopy. Results: 20 patients were included. Follow-up was 10.1 ± 5.2 years. 17 patients received indomethacin for 5.9 ± 5.3 years; 19 received celecoxib, median of 35 months; and five received enalapril, median of 23 months. During indomethacin, a statistically significant increase was observed in the Z-score for stature and weight, without a change in the creatinine clearance. Seven of 17 patients had gastrointestinal symptoms, and upper digestive endoscopy evidenced gastritis in three patients and gastric ulcer in four patients. During celecoxib use, a significant increase was detected in the Z-score for stature and weight and a reduction of hyperfiltration; seven patients presented gastrointestinal symptoms, and upper digestive endoscopy evidenced mild gastritis in three. During enalapril use, no significant changes were observed in the Zscore for stature, weight and creatinine clearance. The conversion to enalapril resulted in a significant reduction in proteinuria.

Results This descriptive study included 22 patients (21 families) with clinical diagnosis of BS. Pathogenic variants in BS-related genes were detected in 19/22 patients. No BS-related genes were detected in three patients (one case of Congenital Chloride Diarrhea and two siblings with clinical Antenal BS that, in fact, had Gitelman Syndrome). We observed that 16/19 BS-confirmed patients had CLCNKB mutations (BS type 3) with a large phenotypical diversity. Among them, the deletion of the entire gene (del 1–20) was the most frequent variant detected. Interestingly, we observed that patients with homozygous or heterozygous del 1–20 presented earlier manifestations than patients with ...

In this document, the SBN Rare Diseases Committee (COMDORA) gives some guidelines on the care of patients with rare kidney diseases. These patients should follow the recommendations for the general population, bearing in mind that, as they have chronic kidney disease, they are included in the risk group for more serious outcomes if they develop Covid-19. Non-essential decision-making procedures should be postponed. In stable cases under appropriate treatment, we must choose to contact our patients remotely, using teleconsultations and home exam collections (if possible). In the presence of a symptom or sign of decompensation of the underlying disease, or infection with Sars-cov-2, advise the patient to seek medical assistance. The patient should not be waiting to get worse. Changes to the prescription should only be made on a scientific basis. Dosage suspension or change is not r...

This Study Group intends to better know our patients, their special characteristics and facilitates the treatment. To present an update on the demographics of the ongoing study participants with interest on renal function status, response to therapy, and extra-renal complications. Patient recruitment to the study is based on informed consent and has been supported by the Brazilian Society of Nephrology, by the creation of an electronic homepage and by the participation in medical meetings and publications in medical periodicals. Our study protocol involves the initial and follow-up questionnaire, the measurement of intraleukocyte cystine content, initiation and follow-up therapy with cysteamine, and clinical patient follow-up based on a protocol of subsidiary exams. We identified 102 patients (42 females) with nephropathic cystinosis in Brazil since 1999. Forty-six children are followed at the Instituto da Criança/SP, 15 at the Hospital Pequeno Príncipe/PR, 12 at the UNICAMP/SP, 10 at the Unidade de Transplante Renal - HCFMUSP/SP and 3 at the Santa Casa/SP; the remaining patients are followed at the Instituto da Criança and at their respective doctors&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; offices in different nephrology services in Brazil. Of these patients, 23/102 (22.5%) have normal renal function, 19/102 (18.6%) are in chronic renal failure with conservative treatment, 26/102 are on dialysis (18 on peritoneal dialysis and 8 on hemodialysis), and 34/102 received a renal transplant. The extra-renal involvement diagnosed was: hypothyroidism in 63 patients, diabetes mellitus in 8 patients, muscular involvement in 7 patients, a compromised central nervous system in 5 patients, hepatic complications in 5 patients, and deglutition dysfunction in 2 patients. During this period, 10/102 patients died. Cysteamine has been used by 81/102 patients (20 children started the therapy under 2 years of age). Growth parameters were improved by cysteamine, mainly in the youngest patients. We used recombinant growth hormone in 15 patients with persistent low growth velocity and stature z score under 2.5%. We could also observe a delay in appearance of extra-renal complications in patients receiving cysteamine. Our study demonstrates the importance of a multi-center study for recruitment, diagnosis and management of rare diseases. This study promotes access to the adequate treatment with profound impact on the quality of life.

We followed 12 children, 6 boys, with a median age at diagnosis of 24.5 months (range 7-137 months) and at the end of the study 157.5 months (range 26.0-224.0 months). All children presented with polyuria and polydipsia, dehydration, and metabolic and electrolyte disturbances with failure to thrive. However, at study entry 5 of 12 patients also had hypophosphatemia, which disappeared after a mean time of 50€22.4 months, 3 of 12 had nephrocalcinosis, and 2 of 12 had typical renal cysts. Despite treatment, hypokalemia was persistent in some patients. During long-term follow-up we observed recovery of growth velocity and adequate metabolic and electrolyte balance. However, we noticed renal and gastrointestinal complications: 2 patients had a perforated gastric ulcer, 1 had a gastric ulcer, and gastritis was detected in 3 children. A decreased glomerular filtration rate was observed in 2 patients during follow-up. Our data emphasize the need for regular surveillance of renal function and gastrointestinal endoscopy in these patients. As an alternative to indomethacin, we present our satisfactory preliminary results with rofecoxib.

The group is composed of 17 patients (ten girls). Sixteen patients presented with bone pain and/or deformities, and in one patient the diagnosis was radiological. All the patients had increased alkaline phosphatase, hypophosphatemia, decreased fractional phosphate tubular reabsorption (TRP) and maximum tubular phosphate reabsorption/glomerular filtration rate ratio (TPO4/GFR). Ten of 17 patients had metabolic acidosis, which was corrected only with the conventional treatment. Potassium citrate was prescribed to the patients who developed hypercalciuria. Excluding one patient with pulmonary dysfunction, the remaining 16 patients were divided into two groups according to the age at treatment onset (T0): group I (GI) &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; or =4 years (n =9) and GII &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;4 years (n =7). GI and GII had similar follow-up periods and treatment protocols. Seven out of nine GI patients underwent orthopedic surgery, in contrast to none of GII. Anthropometric data results showed that within each group there is no difference in weight and stature z -score at T0 and at the end of the observation (Tf), but, when both groups are compared, GII shows higher z-score for stature at T0 (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.05) and at Tf (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.05). Nephrocalcinosis developed in three cases and correlated with hypercalciuria (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.001) and dose of calcitriol (p =0.03). In conclusion, higher stature z-score is associated with early treatment. A careful protocol is recommended to detect such complications as nephrocalcinosis. We suggest potassium citrate for patients with hypercalciuria to avoid calcium precipitation.
