We report a 42-year-old man with subacute infectious endocarditis (IE) with septic pulmonary embolism, presenting rapidly progressive glomerulonephritis and positive proteinase 3-anti-neutrophil cytoplasmic antibody (PR3-ANCA). He had no previous history of heart disease. Renal histology revealed diffuse endocapillary proliferative glomerulonephritis with complement 3- (C3-) dominant staining and subendothelial electron dense deposit, mimicking C3 glomerulonephritis. Successful treatment of IE with valve plastic surgery gradually ameliorated hypocomplementemia and renal failure; thus C3 glomerulonephritis-like lesion in this case was classified as postinfectious glomerulonephritis. IE associated glomerulonephritis is relatively rare, especially in cases with no previous history of valvular disease of the heart like our case. This case also reemphasizes the broad differential diagnosis of renal involvement in IE.

The presence of lupus anticoagulants (LAs) is an important cause of activated partial thromboplastin time (aPTT) prolongation found in children after an infection or during screening tests before surgical intervention. The authors retrospectively reviewed the charts of 68 patients who have been consulted from surgery departments with prolonged aPTT. These patients were reevaluated with aPTT analysis after 1 week. Thirteen patients had normal aPTTs. Therefore, 55 patients remained with prolonged aPTTs. LA positivity was detected in 39 patients. Sixteen of these had prolonged aPTT prior to surgery (41%). Others with LA positivity had systemic lupus erythematosus (SLE; n = 6), infection (n = 5), leukemia (n = 3), hemolytic uremic syndrome (n = 2), epistaxis (n = 2), antiphospholipid syndrome (APS; n = 1), chronic immune thrombocytopenic purpura (n = 1), acute poststreptococcal glomerulonephritis (n = 1), central nervous system (CNS) thrombosis (n = 1), and congenital heart disease (n = 1). None of the patients had bleeding history. LA positivity rarely leads to bleeding and/or thrombosis. Specific therapy is usually not needed. Further prospective multicenter studies are required to understand clinical outcomes and laboratory correlation in children with positive LA.

Two children with congenital heart disease status post surgical correction presented with prolonged constitutional symptoms, hepatosplenomegaly and pancytopenia. Concern for malignancy prompted bone marrow biopsies that were without evidence thereof. In case 1, echocardiography identified a multilobulated vegetation on the conduit valve. In case 2, transthoracic, transesophageal and intracardiac echocardiography were performed and were without evidence of cardiac vegetations; however, pulmonic emboli raised concern for infective endocarditis. Both patients underwent surgical resection of the infected material and had histopathologic evidence of infective endocarditis. Further diagnostics identified elevated cytoplasmic antineutrophil cytoplasmic antibodies and antiproteinase 3 antibodies in addition to acute kidney injury with crescentic glomerulonephritis on renal biopsy. Serologic evidence of infection with Bartonella henselae was observed in both patients. These 2 cases highlight the potential multiorgan involvement that may confound the diagnosis of culture-negative infective endocarditis caused by B. henselae.

Acute kidney injury (AKI) is common in hospitalized patients with mortality varying from 10% to 80%. It is crucial to know the incidence and etiology of AKI to promote prevention strategies. Our study aimed at obtaining a comprehensive review of the pattern and spectrum of patients who presented for emergency hemodialysis to Kasr Al-Aini Hospital between October 2012 and October 2014. We analyzed clinical and laboratory factors in all such patients. Two thousand twenty three patients were included of which patients with AKI were 728 patients (36%). Cardiac diseases were the cause of AKI in 171 patients, other prerenal causes were found in 55 patients, drug induced AKI in 113 patients, and obstetric causes in 48 patients. Glomerulonephritis was responsible for AKI in 101 patients, lupus nephritis was found in 33 patients of them. Patients with chronic kidney disease who presented with acute exacerbation were 243 patients (12%). Patients who were discovered to be with end-stage renal disease during their first presentation itself were 1052 patients (52 %). Diabetes mellitus was present in 50.12%, while hypertension was present in 29.56%. Hepatitis C virus was present in 17.3%, while HBsAg was present in 0.8%. Drugs and obstetric causes represented a larger fraction among our cases than seen in developed countries. Lupus nephritis was also a common cause of AKI.

IgA nephropathy (IgAN) is the most common cause of primary glomerulonephritis worldwide. Up to 30% of cases develop the progressive form of the disease, eventually requiring renal replacement therapy. Diagnosis and risk stratification relies on an invasive kidney biopsy and management options are limited, with recurrence following renal transplantation being common. Thus the quest to understand the pathophysiology of IgAN has been one of great importance. MicroRNAs (miRs) are short nucleotides that suppress gene expression by hybridizing to the 3' untranslated region of messenger RNA (mRNAs), promoting mRNA degradation or disrupting translation. First discovered in 1993, miRs have since been implicated in a number of chronic conditions, including cancer, heart disease and kidney disease. The mounting interest in the field of miRs has led to fascinating developments in the field of nephrology, ranging from their roles as biomarkers for disease to the development of miR antagonists as avenues for treatment. The translational potential for miRs in IgAN is thus well grounded and may represent a paradigm shift in current approaches to the disease. This review aims to summarize the literature with regard to miRs and their roles in IgAN.

The early asymptomatic stage of glomerular injury is a diagnostic challenge in the course of renal and extra-renal disease, e.g., heart insufficiency. It was found that podocin, a podocyte-specific protein present in the urine, may serve as a biomarker in the diagnosis of glomerular disease in humans and animals including glomerulonephritis, glomerulosclerosis, amyloidosis, or nephropathy. Therefore, there is a need of development of the sensitive and straightforward method of urinary podocin identification. In this work, we report our extended research under the glomerular injury investigation in dogs by application of clinical examination and LC-MS-MRM method in the identification of canine podocin in urine samples. The LC-MS-MRM method is based on the identification of podocin tryptic peptide with the 218H-AAEILAATPAAVQLR-OH232 sequence. The model peptide was characterized by the highest ionization efficiency of all the proposed model podocin tryptic peptides in a canine urine sediment according to the LC-MS/MS analysis. The obtained results revealed the presence of the model peptide in 40.9% of dogs with MMVD (active glomerular injury secondary to heart disease = cardiorenal syndrome-CRS) and 33.3% dogs with chronic kidney disease. The potential applicability of the developed methodology in the analysis of podocin in canine urine sediments was confirmed.

Sarcoptes scabiei (S. scabiei), a parasite mite which causes scabies disease resulting in serious public health concern. The long-term scabies disease can lead to complications such as septicemia, acute post-streptococcal glomerulonephritis, heart disease, and secondary infections. Timely treatment to the affected patients is required to control the disease and get rid of the causative agent. Delayed diagnosis and inappropriate treatment can lead to serious consequences. The most common treatment strategy is the use of allopathic medicines which can immediately relieve the patient but have the drawback of side effects. The safe and cost-effective alternative treatment strategy is the use of medicinal plants which have beneficial therapeutic potential against variety of diseases due to the presence of many bioactive phytoconstituents with no or minimal side effects. For the present review, the published articles describing scabies disease and its phytotherapeutic modalities were searched through different data bases including Google Scholar, PubMed, Medline, and ScienceDirect using the keywords like S. scabiei, prevalence of scabies disease, and phytotherapy of scabies. A large number of medicinal plants, such as Melaleuca alternifolia, Curcuma longa, Azadirachta indica, Rosmarinus officinalis, Capsicum annuum, Cinnamomum camphor, Solanum nigrum, and Eupatorium perfoliatum, have been reviewed for the promising future treatments of scabies. All the studied plants have many bioactive compounds with potential therapeutic effects against scabies and can be utilized for therapeutic purposes for this disease. This literature study has limitations because of the lack of sufficient data due to limited pre-clinical trials in this particular area. This review provides a baseline to explore the therapeutic potential of these medicinal plants against skin diseases. However, extensive studies are required to identify, authenticate, and characterize the bioactive compounds present in these plants which may lead to value addition in pharmaceutical industries providing the cost-effective way of treatment with minimal side effects.
