Two similar cases yet very different
Case of a 45 year old female with Acute Kidney Injury
Submitted by: Simran Dash
MBBS: IV | Roll number: 153
I have been given this case to solve in an attempt to understand the topic of "Patient clinical data analysis" to develop my competency in reading and comprehending clinical data including history, clinical findings, investigations and diagnosis and come up with a treatment plan.
The entire real patient clinical problem is presented in the following link:
https://alekyatummala.blogspot.com/2020/09/45-yr-female-with-anasarca.html?m=1
This is the 1st case.
My analysis for this patient is as folows:-
Age: 45 years
Sex: Female
Occupation: Housewife
Chief complaints:
- Pedal edema since 5 days
- Oliguria since 3 days
- Onset- Insidious
- Duration- 6 months
- Progression- Gradually Progressive
- Type- Pitting
- Aggravated on- Walking
- Relieved on- Rest
- Associated complaints-
- Facial puffiness mainly periorbital edema
- Abdominal distension
- Dyspnea (Initially Grade 3 later, Grade 4 according to NYHA)
- Intermittent Palpitations
- Right sided Chest pain, non- radiating
- Renal
- Cardiac
- Hepatic
- Onset- Sudden
- Duration- 3 days
- Progression- Progressed from oliguria to anuria in the last 3 days
- Congestive heart failure
- Malignant Hypertension causing Hypertensive Nephropathy
- Diabetic Nephropathy
- Gives a better idea of all the treatment options received by her.
- Also helps in better monitoring of the patient.
- We can understand if the patient is responding to the specific treatment regime or not, depending upon which either the drugs or their dosages can be changed.
- This rationale makes the data more organized.
- Oliguria
- Hypoalbminenia
- Proteinuria
- Pedal edema progressing to periorbital edema
- Diabetes Mellitus
- Hypertension
- Anemia
- Malnutrition because of excessive proteinuria (which is masked by the anasarca)
- Diabetes mellitus causing Diabetic Nephropathy.
- Congestive Heart Failure
- Hypertensive nephropathy
- Acute Kidney Injury
- Malnutrition
- Malignant Hypertension because of damage to glomeruli and the resulting buildup of excess body fluids.
- Pre-renal AKI: Congestive Heart Failure causing impaired cardiac output leading to renal dysfunction i.e. Cardiorenal syndrome
- Intrinsic AKI: Malignant Hypertension
- Fundoscopy to check hypertensive retinopathy or diabetic retionopathy.
- To rule out Cardiorenal syndrome, additional investigations needed are-
- Cardiac troponins: Rule out Myocardial Infarction.
- Creatine kinase
- LDH levels
- Brain Natriuretic Peptide
- Early biomarkers to confirm Acute Kidney Injury are:
- Neutrophil Gelatinase associated lipocalin (NAGL)
- N Acetyl B-D- Glucosaminidase (NAG)
- Cystatin C
- Kidney Injury Molecule-1 (KIM-1)
- Tests to confirm the suspected Pleural effusion:
- Thoracic Ultrasound
- Contrast Enhanced CT scan
- Pleural tap can be done to find out whether the effusion is exudative or transudative.
- Severe Proteinuria
- Metabolic Acidosis refractory to treatment with bicarbonate.
- Acute pulmonary oedema
- Oliguria
- Erythropoeitin deficiency
- Uremia induced inhibitors of erythropoeisis
- Shortened RBC survival
- Disordered iron hemostasis which could be because of hepcidin excess.
- Tab. OROFER xt
- Inj. Erythropoeitin S.C. twice weekly
- First, not all questions were asked of all participants because interview time was limited.
- However, not all concepts were relevant to every participant, especially if certain symptoms were not initially reported.
- Participants with comorbid conditions could also affect the results because symptoms of another condition could be attributed to anemia of CKD.
- Because of decrease in the ability of kidneys to excrete acids.
- Decrease tubular reabsorption of bicarbonate.
- Insufficient production of bicarbonate in relation to amount of acids synthesized in body and ingested with food.
- It could be because of Congestive Heart Failure impairing the excretion of organic acids leading to accumulation of these acids.
- Cardiac arrest
- Adjunct to adavanced cardiovascualar life support during CPR.
- Severe metabolic acidosis.
- Less urgent metabolic acidosis
- Urine alkalinization
- Antacid
- Hyperkalemia
- Metabolic or respiratory Alkalosis
- Hypercarbic acidosis
- Hypersensitivity
- Hypocalcemia because alkalosis can cause tetany
- Excessive Chloride loss from vomiting or G.I. suctioning
- To relieve heart burn or sour stomach
- Alkalinization of urine
- Acute ingestion of strong mineral acids
- Heart Failure
- Renal insufficiency
- Any edematous or sodium retaining conditions
- Diabetes mellitus
- Hypertension
- Anemia
- Malnutrition
- It is easy to use and consists of only three discrete severity levels but closely correlated with more subjective measures.
- SGA is a reproducible and useful method for assessing the nutritional status of MHD patients.
- It is inexpensive, can be performed rapidly, requires only brief training and gives a global score of protein energy nutritional status.
- Disadvantages of this method include the fact that visceral protein levels are not included in the assessment; it is focused on nutrient intake and body composition.
"SGA-DMS is a reliable method of assessing nutritional status in hemodialysis patients and useful in recommending nutritional support in these patients. However more comparative and longitudinal studies are needed to confirm the validity of this nutrition scoring system in Indian population."
"There are other several methods of nutritional state evaluation available ranging from anthropometric measurements to more elaborate techniques such as DEXA, Bio Impedance Assay but the reliability of these methods in detecting protein-calorie malnutrition and their practicability as not been proven. Moreover, more elaborate methods are costly and time–consuming, which restricts their use to a few research centers."

[05/09/20, 7:42:15 PM] MBBS 2016 UG: Good evening sir, I was going through the case which you have given us for biweekly assessment.
[05/09/20, 7:42:30 PM] MBBS 2016 UG: Does she have pleural effusion?
[05/09/20, 7:49:29 PM] Post residency PG 1: Possible but will need to be confirmed on Usg. Have they mentioned that report?
[05/09/20, 8:08:55 PM] MBBS 2016 UG: No sir, there is no report of the ultrasound.
[05/09/20, 8:09:17 PM] MBBS 2016 UG: Sir, I have another doubt too.
[05/09/20, 8:10:01 PM] Post residency PG 1: Ask Alekya about the missing data. She will upload them.
[05/09/20, 8:10:07 PM] Post residency PG 1: Please share
[05/09/20, 8:10:08 PM] MBBS 2016 UG: She still has very severe metabolic acidosis, even after dialysis.
[05/09/20, 8:10:14 PM] MBBS 2016 UG: why is it like that?
[05/09/20, 8:10:25 PM] MBBS 2016 UG: Okay sir, I will ask ma'am.
[05/09/20, 8:11:46 PM] Post residency PG 1: Will need to be sure that the ABGs are Post dialysis but yes it may take many more sessions to get the stranded H+ ions out
[05/09/20, 8:12:33 PM] MBBS 2016 UG: Okay sir.
[05/09/20, 8:13:44 PM] MBBS 2016 UG: Yes sir, atleast there is more than a 2 fold increase in the bicarbonate level following dialysis.
[05/09/20, 8:24:10 PM] Post residency PG 1: And still the ph didn't normalize?
[05/09/20, 8:41:45 PM] MBBS 2016 UG: The ph has normalized now sir
[05/09/20, 8:41:55 PM] MBBS 2016 UG: but the bicarbonate is still less
[05/09/20, 8:43:44 PM] MBBS 2016 UG: As for the question you asked in the group sir, the child has Eissenmenghar syndrome right sir?
[05/09/20, 8:45:05 PM] Post residency PG 1: What's the current bicarbonate level?
[05/09/20, 8:45:51 PM] Post residency PG 1: Can you share more history about this medical student named Eissenmengers? How did he discover it?
Also what is the primary problem in the child that led to the syndrome?
[05/09/20, 8:46:34 PM] MBBS 2016 UG: Current bicarbonate level is 15.5 mmol/L sir.
[05/09/20, 8:46:40 PM] MBBS 2016 UG: Yes sir I would.
[05/09/20, 8:47:48 PM] Post residency PG 1: 👍
[05/09/20, 8:54:20 PM] MBBS 2016 UG: "The first clinical description originates from the Viennese physician Victor Eisenmengar(29. Jan. 1864 - 11. Dec. 1932). In 1897 he reported on a 32-year-old man with cyanosis and dyspnea since infancy. This patient had a reasonably active life until 3 years before his death, when dyspnea increased and right heart failure began. He succumbed suddenly after massive hemoptysis. Autopsy revealed a nonrestrictive membranous malalignment ventricular septal defect (VSD), marked right ventricular hypertrophy, an overriding aorta, and atheromatosis of the major pulmonary arteries."
[05/09/20, 8:54:22 PM] MBBS 2016 UG:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3083816/
[05/09/20, 8:55:13 PM] MBBS 2016 UG: In her case, it is because of the VSD which led to left-to-right shunt sir.
[05/09/20, 8:55:36 PM] Post residency PG 1: 👍👏👏
[05/09/20, 8:57:55 PM] MBBS 2016 UG: Thank you sir.
[06/09/20, 11:11:19 AM] MBBS 2016 UG: Good morning sir. In the 45 year old female with anasarca, I was a little confused with the ECG findings.
[06/09/20, 11:12:07 AM] MBBS 2016 UG: There is abnormal progression of R wave, so could it possibly be that she developed a silent MI before?
[06/09/20, 11:12:38 AM] MBBS 2016 UG: This is the ECG
[06/09/20, 11:18:04 AM] MBBS 2016 UG: And also the ECG post dialysis looks normal. Could it be due to hypokalemia?
[06/09/20, 11:47:53 AM] MBBS 2016 UG: And sir I have another doubt too. Is it the heart failure which led her to develop AKI or is it vice-versa?
[06/09/20, 1:59:46 PM] Post residency PG 1: What is abnormal about the progression of this R wave?
[06/09/20, 2:00:48 PM] Post residency PG 1: Please share both the EcGs side by side so that we may compare
[06/09/20, 2:01:53 PM] Post residency PG 1: How would heart failure cause AKI? What are her urinary findings that go against pre renal causes and suggest glomerular injury?
[06/09/20, 3:04:33 PM] MBBS 2016 UG: The QRS complex in V4 has a small r wave and a deep S wave sir.
[06/09/20, 3:05:54 PM] MBBS 2016 UG: The first being BUN:Serum creatinine ratio is less than 20:1 sir. That suggests it’s more likely to be Diabetes causing the glomerular injury.
[06/09/20, 3:06:05 PM] MBBS 2016 UG: Hypertension too sir. This is the ECG post dialysis.
[06/09/20, 3:10:44 PM] MBBS 2016 UG: Cardiorenal syndrome sir? Low cardiac output in heart failure patients can result in decreased blood flow to the kidneys which can lead to progressive deterioration of kidney function. As a result, diuresis of these patients will result in hypovolemia and pre-renal azotemia.
[06/09/20, 5:21:33 PM] Post residency PG 1: Sir... In the case... Is the renal failure primarily due to uncontrolled hypertension?
[06/09/20, 5:21:34 PM] Post residency PG 1: Or is it a complication of diabetes sir?
[06/09/20, 5:21:35 PM] Post residency PG 1: Like diabetic nephropathy sir
[06/09/20, 5:21:35 PM] Post residency PG 1: Or is it correct to consider hypertension being a sequelae of renal failure sir
[06/09/20, 5:21:37 PM] Post residency PG 1: Yes the chicken and egg conundrum that plagues most such scenarios. 👍
We expect her renal issues to be multifactorial. Her current glomerular injury manifested in nephrotic proteinuria is surely due to both diabetes and hypertension but what precipitated her current acute renal failure is still grey. Possibly she may have taken pain killers that could have precipited reduced renal perfusion
[06/09/20, 5:25:08 PM] Post residency PG 1: Does this patient demonstrate low cardiac output in terms of her LV ejection fraction?
[06/09/20, 5:27:01 PM] Post residency PG 1: Can this change be due to the lead placement where the leads may not have been placed properly. What you see as V4 in the previous EcG may have been V3 taken twice?
[06/09/20, 5:55:13 PM] MBBS 2016 UG: No sir she has HFpEF.
[06/09/20, 5:55:41 PM] MBBS 2016 UG: Okay sir.
[06/09/20, 5:56:29 PM] MBBS 2016 UG: Yes sir that’s possible. Then her ECG findings are normal right.!
[06/09/20, 5:58:06 PM] Post residency PG 1 : 👍
[05/09/20, 8:12:07 PM] MBBS 2016 UG: I just wanted to ask if there is any ultrasound report of the patient?
[05/09/20, 8:19:40 PM] MBBS 2015 intern: No
[05/09/20, 8:19:49 PM] MBBS 2015 intern: We only did renal Doppler
[05/09/20, 8:19:54 PM] MBBS 2015 intern: But everything's normal
[05/09/20, 8:20:54 PM] MBBS 2016 UG: Okay ma’am. But did she have pleural effusion?
[05/09/20, 8:23:42 PM] MBBS 2015 intern: No
[05/09/20, 8:31:22 PM] MBBS 2016 UG: Okay. Thank you ma'am.
[05/09/20, 8:32:33 PM] MBBS 2016 UG: And ma'am you mentioned in your blog that she had facial puffiness, was it associated with Periorbital edema?
[05/09/20, 8:32:46 PM] MBBS 2015 intern: Yeah
[05/09/20, 8:33:11 PM] MBBS 2016 UG: Thank you ma'am😀
[05/09/20, 9:14:06 PM] MBBS 2016 UG: Ma'am did she have shifting dullness too because of the abdominal distension?
[05/09/20, 9:24:20 PM] MBBS 2015 intern: No
[05/09/20, 9:24:29 PM] MBBS 2015 intern: It's not like ascitis
[05/09/20, 9:24:39 PM] MBBS 2015 intern: Only distension
[05/09/20, 9:29:31 PM] MBBS 2016 UG: Accha okay maam. Thank you.
[06/09/20, 7:14:40 PM] MBBS 2016 UG: Ma'am I wanted to ask how many units of blood did she receive?
[06/09/20, 7:15:08 PM] MBBS 2015 intern: Only 1 till now
[06/09/20, 7:15:15 PM] MBBS 2015 intern: 450ml
[06/09/20, 7:16:23 PM] MBBS 2016 UG :okay ma'am
[06/09/20, 7:16:27 PM] MBBS 2016 UG: Thank you
[06/09/20, 7:16:32 PM] MBBS 2016 UG: :)

ReplyDeleteNephrotic syndrome is an expression of a cause and not a cause for something.
Here the cause of her nephrotic syndrome is chronic glomerular injury but what is the cause of her acute renal failure is still unclear
Yes sir. I will make the required corrections.
