low creatinine and autoimmune disease
Possible causes of a higher creatinine level include: If you have high creatinine levels, symptoms may include: Your doctor can use multiple tests to check your creatinine level. Usually, your body will make the antibodies for a short time, anywhere from a few weeks to two years. Goodpasture's Syndrome | National Kidney Foundation Low serum alkaline phosphatase activity due to asymptomatic hypophosphatasia in a teenage girl Hypophosphatasia was initially considered an unlikely diagnosis for this patient given her lack of characteristic skeletal abnormalities. It is intended for informational purposes only. But if you're experiencing anything that concerns you, you should make an appointment with your doctor. Symptoms of low creatinine will vary depending on the underlying condition but can include: Low muscle mass: Lack of strength, difficulty exercising, a thin or frail body. PDF Traci N. Bethea, PhD HHS Public Access Amelia K. Wesselink, PhD They are also dependent on blood volume. Chronic kidney disease (CKD)or chronic renal failure (CRF), as it was historically termedis a term that encompasses all degrees of decreased renal function, from damaged-at risk through mild, moderate, and severe chronic kidney failure. Nephrology consultation is indicated when the estimated GFR is less than 30 mL per minute per 1.73 m2, or earlier if necessary (Table 11).9,15 Partnership between primary care physicians and nephrologists is key to successful CKD management. A 33 percent decrease in GFR may raise the creatinine level from 0.8 to only 1.2 mg per dL (70.72 to 106.08 mol per L). A normal urinary albumin/creatinine ratio is less than 30 mg per g. Patients with albumin/creatinine ratios of 30 to 300 mg per g are classified as having microalbuminuria, and those with ratios greater than 300 mg per g are classified as having macroalbuminuria.10,11. Accessed April 26, 2021. Hashimoto's autoimmune thyroiditis. This means that there will be lower levels of creatinine in the blood, which can be checked with a simple blood test called a serum creatinine test. Creatine for Fibromyalgia and Chronic Fatigue Syndrome Itching for no reason? Immune system may be at fault It's estimated that chronic kidney disease affects about one in seven American adults. Although creatine is made naturally in the body, a small amount comes from food, so low levels of creatinine could relate to diet. The creatinine then exits the body through urination. Our kidneys play many important roles keeping our bodies in balance. Debra Rose Wilson, Ph.D., MSN, R.N., IBCLC, AHN-BC, CHT, Everything you need to know about electrolytes. The causes of low blood creatinine are: Loss of muscle mass : the most frequent reason why the production of creatinine in the body decreases is the loss of muscle mass due to aging or a significant and sudden weight loss. If further testing rules out a muscle disease, your doctor may suggest lifestyle and diet changes and then retest your level at a later time. Reduced blood flow to the kidneys can interfere with the kidney's ability to filter blood. Low muscle mass can also result from malnutrition, or from eating a low-meat or low-protein diet. For example, as people age, their creatinine level may decrease as they lose muscle mass -- particularly if they are not exercising regularly. Accessed April 26, 2021. Creatine phosphokinase (a.k.a., creatine kinase, CPK, or CK) is an enzyme (a protein that helps to elicit chemical changes in your body) found in your heart, brain, and skeletal muscles. If you're overweight or obese, then try to lose weight. Nephrology consultation is indicated when the estimated GFR is less than 30 mL per minute per 1.73 m, Exposure to certain chemicals and environmental conditions (e.g., lead, cadmium, arsenic, mercury, uranium), Minority status (e.g., blacks, American Indians, Asians, Pacific Islanders), Primary: lupus nephritis, vasculitis, membranous nephropathy, minimal change disease, focal segmental glomerulosclerosis, immunoglobulin A nephropathy, Secondary: infections (e.g., hepatitis B and C, human immunodeficiency virusassociated bacterial endocarditis), amyloidosis, heroin use, malignancy (e.g., leukemia, Hodgkin lymphoma, carcinoma), Urinary tract infections, nephrolithiasis, obstruction, sarcoidosis, multiple myeloma, drug toxicity (e.g., proton pump inhibitors, lithium, nonsteroidal anti-inflammatory drugs), Chronic Kidney Disease Epidemiology Collaboration, Age; sex; race; and serum urea, nitrogen, albumin, and creatinine levels, National Kidney Disease Education Program, At the time of diagnosis of type 2 diabetes mellitus, Five years after diagnosis of type 1 diabetes mellitus, Microalbuminuria in patients who have had type 1 diabetes for more than 10 years, Microalbuminuria in the presence of diabetic retinopathy, Absence of albuminuria in patients with stage 3 to 5 chronic kidney disease, More than 30 percent reduction in GFR within two to three months after initiation of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, Rapidly decreasing GFR (more than 4 mL per minute per 1.73 m, Rapidly increasing proteinuria or nephrotic syndrome, Signs or symptoms of other systemic disease, Diagnose and treat CKD, treat comorbid conditions, slow progression of CKD, reduce cardiovascular risk, Acute interstitial nephritis, crystal nephropathy, Chinese herbal preparations containing aristolochic acid, Acute and chronic interstitial nephritis, impaired glomerular hemodynamics, Estimated GFR 10 to 30 mL per minute per 1.73 m, Estimated GFR < 30 mL per minute per 1.73 m, Estimated GFR 30 to 60 mL per minute per 1.73 m, Estimated GFR 16 to 29 mL per minute per 1.73 m, Estimated GFR 15 mL per minute per 1.73 m, Estimated GFR 20 to 49 mL per minute per 1.73 m, Estimated GFR 10 to 19 mL per minute per 1.73 m, Avoid if serum creatinine level is greater than 1.5 mg per dL (132.60 mol per L) in men or greater than 1.4 mg per dL (123.76 mol per L) in women, and in patients older than 80 years, Risk factors for sexually transmitted disease, Autoimmune disease (e.g., systemic lupus erythematosus, cryoglobulinemia), Urinary tract infection, obstruction, or stone, Diabetes mellitus (5 to 10 years' duration), Microalbuminuria with evidence of retinopathy and elevated BP, Severe BP elevation, often with target organ damage, Males and females are affected equally in every generation, Autosomal dominant polycystic kidney disease, Sex-linked recessive disease (e.g., Alport syndrome), Autosomal recessive polycystic kidney disease, Bruit (renal artery stenosis, fibromuscular dysplasia), flank pain, distended bladder, Rash and skin changes in autoimmune disease or neurofibromatosis, Abnormal serum and urine protein electrophoresis, Multiple myeloma, amyloidosis, light-chain deposition disease, Decreased serum complement levels C3 and C4, Poststreptococcal glomerulonephritis, membranoproliferative glomerulonephritis, lupus nephritis, cryoglobulinemia, Atheroembolic disease, tubulointerstitial disease, Positive antiglomerular basement membrane antibody test, Goodpasture syndrome, antiglomerular basement membraneassociated rapidly progressive glomerulonephritis, Positive antineutrophil cytoplasmic antibody test, Wegener granulomatosis, microscopic polyangiitis, pauci-immune rapidly progressive glomerulonephritis, Membranous nephropathy, membranoproliferative nephritis, Mixed cryoglobulinemia, membranoproliferative glomerulonephritis, membranous nephropathy, May be useful in investigation of venous thrombosis, less so in arterial stenosis.
