Renal Failure: Dose Adjustments

Renal Failure: Dose Adjustments

In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Chronic Kidney Disease III: Interprofessional Care

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Urinary Tract Calculi I: Introduction

Urinary Tract Calculi I: Introduction

Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Area of Science:

Nephrology
Endocrinology
Pulmonology

Background:

Nephrocalcinosis and renal failure can be caused by hypercalcemia.
Hypercalcemia in renal failure typically involves suppressed parathormone (PTH) and vitamin D levels.
Non-PTH-mediated hypercalcemia requires thorough investigation.

Observation:

A patient presented with nephrocalcinosis and renal failure, exhibiting hypercalcemia.
Intact parathormone (iPTH) and 1,25 dihydroxy-vitamin D levels were inappropriately normal despite renal failure.
Further investigation was prompted to identify the non-PTH-mediated cause of hypercalcemia.

Findings:

Sarcoidosis was diagnosed as the underlying cause of hypercalcemia.
Treatment with glucocorticoids partially reversed renal failure.
Glucocorticoid therapy effectively controlled hypercalcemia.

Implications:

This case underscores the importance of carefully interpreting laboratory parameters, including iPTH and vitamin D metabolites, in patients with renal failure.
Sarcoidosis should be considered in the differential diagnosis of non-PTH-mediated hypercalcemia, even in the presence of renal failure.
Timely diagnosis and management of sarcoidosis-related hypercalcemia can lead to improved renal outcomes.
