Affected individuals manifest clinically with tumors involving multiple organs including hemangioblastoma of the central nervous system and retina, cystic kidney disease, renal cell carcinoma (RCC), pheochromocytoma, and pancreatic neuroendocrine tumors. Its diagnosis is based on genetic testing and clinical criteria in suspected patients. Treatment principles are to save organs and periodic surveillance for in-time tumor detection and appropriate follow-ups. This case report presents a 47-year-old woman with five years history of abdominal pain alongside long-standing headaches and progressive hearing loss. On imaging, multiple suspicious tumors throughout her body were detected and she proceeded to surgical resection. She was finally diagnosed with RCC, central nervous system tumor hemangioblastoma, and pancreatic cyst. The patient underwent a right-sided nephrectomy and Sunitinib therapy. She is continuing therapy and currently does not have any sign of metastasis. Due to her constellation of tumors VHL disease was suspected. Although she did not have any positive family history, the VHL diagnosis was conducted based on clinical criteria. The case emphasized the importance of timely recognition and evaluation of suspected cases and evidence base surveillance. Physician familiarity with the underestimated disease is of paramount importance.","PeriodicalId":16964,"journal":{"name":"Journal of Renal Endocrinology","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78560127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The common symptoms of COVID-19 disease which have affected a large population are common cold, fatigue, headache and fever. However, complications such as multiple organ failure, acute respiratory syndrome and septic shock are seen in about 5% of patients with persisting severe symptoms and post-COVID syndrome. The COVID-19 acute kidney injury in patients displays damage in the kidney, proteinuria, hematuria and elevated serum creatinine. The symptoms of acute kidney injury vary from mild to severe, which necessitates proper clinical management and renal replacement therapy (RRT). Therefore, it is necessary to understand the pathophysiology of acute kidney injury involving infiltrated immune cells, thrombosis, and cytokine regulation. There is no definite treatment for acute kidney injury; the strategy for preventing the complications will only come through clinical experience. Therefore, more studies are needed for the proper understanding of the disease etiology in acute kidney injury patients with COVID-19.

Objectives: To test the reducing therapeutic effect of oral vitamin C supplements on hepcidin levels and iron status among HD patients with FID anemia. Patients and Methods: This study is an interventional prospective cohort study; 48 prevalent HD patients were enrolled. Group one: 31 patients who received the conventional treatment of erythropoietin stimulating agents together with oral supplementation of vitamin C 500 mg every other day dose for 3 months. Group two: 17 patients who received only the conventional therapy of erythropoietin stimulating agents. Patients with hemoglobin level <11 g/dL, ferritin level >200 ng/mL and transferrin saturation (TSAT) >20 % were included. Laboratory parameters: serum hepcidin, high-sensitivity C-reactive protein (hs-CRP) titre, CBC, and iron indices were measured at baseline and after 3 months. Results: On comparing the two groups, oral vitamin C in group 1 resulted in a statistically significant reduction in hepcidin levels [mean 2506.456 ± 1320.53 pg/mL to 1748.396 ± 1432.28 pg/mL (P = 0.03)], and a significant reduction in hs-CRP level [mean 8603.236 ± 2547.77 ng/mL to 5611.296 ± 2829.27 ng/mL] (P = 0.001) after three months of treatment in comparison to control group.

There has been a lot of interest recently in the non-classical effects of 25(OH) vitamin D (calcidiol), including its association with erythropoiesis and anemia pathogenesis. Objectives: To study the relation between anemia and vitamin D status in patients on regular HD Results: This study is a cross-sectional study that included 90 patients on regular HD. Vitamin D status was classified into deficient (<20 ng/ mL), insufficient (20-30 ng/mL) and sufficient (>30 ng/mL). The level of vitamin D measured in the patients ranged between 3.5 to 66 ng/mL with median of 16.35 ng/mL. There were statistically significant positive correlations between vitamin D levels and the level of hemoglobin (P<0.001), serum calcium levels (P<0.001) and serum PO4 levels (P=0.023). Higher hemoglobin levels were statistically related to both higher vitamin D values (P<0.001) and higher serum calcium concentration P<0.001). Meanwhile, a significant negative correlation was found between hemoglobin levels and serum PTH values (P<0.001).

Patients with underlying diseases, such as those with end-stage kidney disease (ESKD) on dialysis, are at greater risk. Objectives: The aim of our study to assess the outbreak and impact of COVID-19 on dialysis patients. Patients and Methods: Our study prospectively assessed and followed 442 patients with ESKD undergoing dialysis [390 patients on maintenance hemodialysis (HD) and 52 patients on peritoneal dialysis (PD)] for outbreak and impact of COVID-19 on these patients during the period from April 22, 2020 until March 23, 2021 in Al Khezam dialysis center, Kuwait. Age, gender, nationality, original kidney disease, history of hypertension (HTN), diabetes mellitus (DM), ischemic heart disease (IHD), congestive heart failure (CHF), bronchial asthma (BA), chronic obstructive pulmonary disease (COPD), history of pulmonary embolism (PE) and source of infection were analyzed. Symptoms as fever, fatigue, cough, loss of smell and taste and chest pain were recorded, the need for ICU admission, mechanical ventilation (MV), extracorporeal membrane oxygenation (ECMO), medications were recorded. The need to shift to continuous renal replacement therapy (CRRT) and outcomes (complications and mortality) were analyzed. Results: Our study reported that 102 out of 442 (23%) dialysis patients [97 out of 390 (24.8%) HD patients and 5 out of 52 (9.6%) PD patients] got infected with COVID-19 and reinfection reported in 4 out of 97 (4%) COVID-19 HD patients. Around 27% of COVID-19 HD patients had fever, 19% had fatigue, 8% had cough, 4% had loss of smell, 4% had loss of taste, 4% had chest pain and 40% of COVID-19 PD patients had fever. Fifteen out of 97 (15 %) COVID-19 HD patients needed ICU admission, 12 out of 97 (12 %) COVID-19 HD patients needed MV. A 33 out of 97 (34%) COVID-19 HD patients and 4 out of 5 (80%) COVID-19 PD patients needed to switch to CRRT.

The spectrum of nephrotoxicity attributed to NSAIDs includes mainly acute tubulointerstitial nephritis. However, much less attention has been given to drug-induced glomerular injury. NSAIDs treating patients presenting with nephrotic syndrome may have a variety of glomerular changes indistinguishable from those found in idiopathic minimal change disease (MCD), for example. The clinical presentation is typically abrupt with nephrotic syndrome while in the elderly it can present as acute renal failure from the beginning. We present an MCD-NSAID induced in elderly patient and discuss possible pathogenic mechanism, thinking about on the indiscriminate use of NSAIDs. Here we report the case of a 66-year-old woman with a history of nephrotic syndrome and hypertension without an apparent secondary etiology. However, an exhaustive history showed and indiscriminate use of NSAIDs. Renal biopsy showed a MCD with a mild interstitial nephritis. To our knowledge the morphology of drug-induced diseases often does not differ from the primary forms, making the distinction difficult. There are subtle clues, although the dialogue between clinician and pathologist is essential to reach an etiological diagnosis. Physicians should suspect glomerulonephritis in patients who receive drugs and its management must be determined based on the histological characteristics of the disease. Although corticosteroid therapy seems to be of value, the effectiveness of this approach must still be tested in randomized and multicentric clinical trials.","PeriodicalId":16964,"journal":{"name":"Journal of Renal Endocrinology","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81878104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
