Renal disorders in pregnancy include pregnancy-related acute kidney injury (AKI) and pre-existing chronic kidney disease (CKD), which are risky for both the mother and the fetus. Here, we present the epidemiology and outcomes of pregnancy-related acute kidney injury and CKD in pregnancy at our tertiary care center. We studied the maternal and fetal outcomes of AKI and CKD in pregnancy. Pregnant females and women up to 6 weeks postpartum with AKI or CKD were included in the study; those aged <18 years were excluded. Of 70 cases, 55 had AKI, 10 had AKI and CKD, and 5 had CKD (two were at CKD Stage 5D). The mean age was 27.5 ± 5.4 years, and the mean gestational age was 28.6 ± 8.2 weeks. Sepsis was the most common cause of AKI, followed by pre-eclampsia (21/65). Of the mothers, 48 out of 68 recovered completely (two were already on maintenance hemodialysis), and 10 died. Twenty patients required hemodialysis, nine of whom recovered completely, one progressed to CKD, four became dependent on dialysis, and six died. Regarding the fetal outcomes, 28 were normal-term deliveries, seven were medically terminated, and 35 died. Hypertension, sepsis, metabolic acidosis, raised bilirubin, and the need for hemodialysis were significantly associated with poor maternal outcomes. Raised bilirubin was the only maternal factor significantly associated with poor fetal outcomes. AKI and CKD in pregnancy are associated with higher morbidity and mortality in both the mother and fetus; hence, the focus must be on prevention through regular antenatal checkups.

Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Renal Failure: Dose Adjustments01:11

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...

Hormonal Regulation01:33

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant

In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...
