  • Focal Segmental Glomerulosclerosis in Systemic Lupus Erythematosus
    Relato de Caso Focal Segmental Glomerulosclerosis in Systemic Lupus Erythematosus: One or Two Glomerular Diseases? Glomerulosclerose Segmentar e Focal em Lúpus Eritematoso Sistêmico: Uma ou Duas Doenças? Rogério Barbosa de Deus1, Luis Antonio Moura1, Marcello Fabiano Franco2, Gianna Mastroianni Kirsztajn1 1 Nephrology Division and 2 Department of Pathology - Universidade Federal de São Paulo – EPM/UNIFESP- São Paulo. ABSTRACT Some patients with clinical and/or laboratory diagnosis of systemic lupus erythematosus (SLE) present with nephritis which from the morphological point of view does not fit in one of the 6 classes described in the WHO classification of lupus nephritis. On the other hand, nonlupus nephritis in patients with confirmed SLE is rarely reported. This condition may not be so uncommon as it seems. The associated glomerular lesions most frequently described are amyloidosis and focal segmental glomerulosclerosis (FSGS). We report on a 46 year-old, caucasian woman, who fulfilled the American College of Rheumatology criteria for SLE diagnosis: arthritis, positive anti-DNA, ANA, anti-Sm antibodies, and cutaneous maculae. During the follow-up, she presented arthralgias, alopecia, vasculitis, lower extremities edema and decreased serum levels of C3 and C4. Proteinuria was initially nephrotic, but reached negative levels. The serum creatinine varied from 0.7 to 3.0 mg/dl. The patient was submitted to the first renal biopsy at admission and to the second one, 3 years later, with diagnosis of minimal change disease and FSGS, respectively. No deposits were demonstrated by immunofluorescence. In the present case, we believe that the patient had SLE and developed an idiopathic disease of the minimal change disease-FSGS spectrum.

  • What Is Lupus Nephritis
    What is lupus nephritis (LN)? Lupus nephritis (LN) is inflammation of the kidney that occurs as a common symptom of systemic lupus erythematosus (SLE), also known as lupus. Proteins in the immune system called antibodies damage important structures in the kidney. ⅱ Why are the kidneys important? To understand how lupus nephritis damages the kidney, it is important to understand how the kidneys work. The kidneys’ main function is to filter out excess waste and water from the blood through the urine. Kidneys also balance the salts and minerals circulating in the blood, help control blood pressure and make red blood cells. So, when the kidneys are damaged or fail, they can’t do their job as well. As a result, the kidneys are not able to filter out waste and water into the urine causing it to stay in the blood. What are the signs and symptoms of LN? Signs to ask the doctor about include blood in the urine or foamy urine which can mean that there is excess protein. Other signs to notice are swelling of legs, ankles, hands or tissue around the eyes as well as weight gain that can be caused by fluid the body isn’t getting rid of. ⅲ Symptoms of lupus nephritis also include high blood pressure, joint/muscle pain, high levels of waste (creatinine) in the blood, or impaired/failing kidney. ⅳ How common is LN? Lupus nephritis is the most common complication of lupus. Five out of 10 adults with lupus will have lupus nephritis, while eight out of 10 children with lupus will have kidney damage, which usually stems from lupus nephritis.

By JOHN GRAY, M.D. (Reader in Pathology, British Post-Graduate Medical School.) In some ways, classification of nephritis is a rather discouraging, as well as a difficult, task, for it is likely that with fuller knowledge of causation we will eventually be enabled to improve on and to simplify any classification possible at present. In the meantime, it is very difficult to decide on the respective merits of the numerous classifications suggested. On the other hand, however, it is true that the multiplicity of the terms which have been used to define various groups of nephritic cases rather tends to exaggerate the number of really important differences of opinion. Many opposing terms in use imply little fundamental difference of opinion, and simply indicate a preference for some particular label for a given type of case. On many points there is, except for this question of nomenclature, fairly general agreement, and it is perhaps as well to begin by indicating some of these, before entering on any discussion of those of a more controversial nature. Few, for instance, would object to the statement that the terms acute, sub- acute, and chronic nephritis provide a useful primary grouping for the majority Protected by copyright. of cases of true nephritis; nor, one thinks, would many take exception to the statement that, of the allied diseases which must be considered with nephritis, easily the most important is non-nephritic hypertension-whatever term is used to describe that condition.

  • People with Lupus Are Much More Likely to Have Kidney Disease Than People Who Don't Have Lupus
    Lupus and kidney disease What does kidney disease have to do with lupus? People with lupus are much more likely to have kidney disease than people who don't have lupus. The kidneys are the organs that make urine. Kidneys filter the blood by putting the waste products into the urine where they can leave the body. Kidney disease can cause blood and protein in the urine, swelling of the body, high blood pressure, and other symptoms. "Lupus nephritis" is the medical name for a type of kidney disease in people with lupus. People who have lupus can also get kidney disease caused by other problems. For example, if someone with lupus also has diabetes, the diabetes might be the cause of kidney problems. The way we find out is by doing a kidney biopsy. Types of Lupus Nephritis: There are several types or “classes” of lupus nephritis. They range from Class I to Class 6: Class 1 disease is mild, Classes 2 and 5 are moderate Classes 3 and 4 are aggressive, Class 6 indicates severe non-reversible disease. What are the symptoms of lupus nephritis? Foamy Urine- This is often one of the first signs of lupus nephritis Blood in the Urine- This is also often one of the first signs of lupus nephritis Swelling- Usually in the legs, feet, or ankles and less often in the hands or face. This tends to worsen as the day progresses or after sitting (this is called edema) High Blood Pressure Changes in Frequency of Urination– Either much more or much less Vomiting- Toxins that build up because the kidney is unable to remove them from the body can result in abnormal function of the liver and the process of digestion.

They have three main functions: (1) remove waste products, (2) balance our bodies’ chemicals, and (3) produce essential hormones. ● The kidneys filter approximately 50 gallons of blood every day; in general, a healthy adult will eliminate approximately one to two quarts of urine daily. If the kidneys do not function properly, wastes accumulate in the body. The progressive loss of kidney function eventually leads to end-stage renal disease (ESRD), or kidney failure, resulting in the need for either dialysis or kidney transplantation. ● The National Kidney Foundation (NKF) estimates that 1 in every 9 adults in the United States, more than 20 million people, has chronic kidney disease (CKD) and that more than 20 million others are at increased risk for the disease.

Introduction The frequency of urinary tract infections (UTIs) is second only to that of respiratory tract infections in the pediatric population. UTIs often are separated into infections of the lower urinary tract that involve the bladder and urethra and those of the upper tract that involve the kidneys, renal pelvis, and ureters. Infections of the upper tract are designated pyelo- nephritis. A complicated UTI, whether of the upper or lower tract, usually is associated with an underlying condition that increases the likelihood of a therapeutic failure. Underlying conditions include abnormal anatomy, urologic dysfunction, the presence of an indwelling catheter, or isolation of a multiresistant organism. Epidemiology Although the prevalence of UTI has been studied in a variety of patient populations, there are fewer data regarding the prevalence of pyelonephritis due, in part, to the difficulty in distinguishing upper from lower tract disease. The prevalence of UTI is influenced by factors such as age, sex, population sample, urine collection method, testing methodolo- gies, diagnostic criteria, and culture. Age and sex are the most important factors.

The prototype of acute glomerulonephritis is acute post-infectious glomerulonephritis. Recently, increased cases of glomerulopathy have been associated with bacterial, viral, and other infections. Acute nephritic syndrome is part of glomerulonephritis with an acute beginning, characterized by hematuria, hypertension, edema, and oliguria due to the reduction of glomerular filtration reflected in an increase of nitrogen compounds. Development: This paper shows a male infant at 2 years and 7 months of age with nephritic syndrome associated to a skin infection, pneumonia, and hepatitis A virus infection. Conclusion: Acute glomerulonephritis may be associated to streptococcus or another coincidental infection. Children with skin infection, hepatitis A, or pneumonia who reveal abnormal urinalysis, hypertension, azotemia, or oliguria should be evaluated for concomitant glomerulonephritis.
