[12-06-2025 10.15] PPM 1: Wards now:
23M with nephrotic syndrome since 3 years, iatrogenic Cushing's and iatrogenic type 2 diabetes
[13-06-2025 17:19] PPM 1: 👆@PPM 3 can an LLM analyse and suggest optimization of further plans for this patient shared yesterday and archived here?👇
[13-06-2025 17:56] PPM 3: Based on the complex case of this 23M with steroid-resistant FSGS, iatrogenic Cushing's, diabetes, and active cellulitis/necrotizing fasciitis, here's an optimized management plan addressing critical issues:
### *Immediate Priorities (SICU Setting)*
1. *Infection Control*
- Surgical consult STAT for debridement if necrotizing fasciitis suspected
- Broad-spectrum IV antibiotics: *Vancomycin + Piperacillin-Tazobactam* (cover MRSA/Gram-negatives)
- Adjust based on cultures/sensitivity
- Discontinue all non-essential immunosuppression (mycophenolate already stopped)
2. *Diabetes Optimization*
- *Switch to Insulin*: Discontinue metformin during acute illness
- Basal-bolus regimen:
- Long-acting (e.g., Glargine) + Rapid-acting (Aspart/Lispro) before meals
- Target glucose: 140-180 mg/dL (ICU setting)
- Monitor q2h glucose, electrolytes, anion gap
3. *Corticosteroid Taper*
- Current prednisolone 10mg/week is subtherapeutic for FSGS but unsafe with diabetes/infection
- *Immediate plan*:
- Stop weekly dosing → convert to *hydrocortisone 20mg/day IV* (physiologic dose for adrenal suppression)
- Gradually taper by 2.5mg/week after infection resolution
---
### *Nephrotic Syndrome Re-Evaluation*
1. *Diagnostic Workup*
- Urgent labs: Albumin, proteinuria PCR, lipid profile, Tacrolimus level
- Renal function: Creatinine, eGFR, electrolytes
- Serologies: Anti-PLA2R, hepatitis/HIV screen
2. *Immunosuppression Revision*
- *Avoid steroids*: Contraindicated with active infection/diabetes/Cushing's
- *First-line: **Low-dose Tacrolimus* restart (target trough 3-5 ng/mL)
- Monitor glucose/drug levels weekly
- Rationale: Past remission (2017-2021), now less nephrotoxic than uncontrolled proteinuria
- *Second-line: **Rituximab* (after infection clearance)
- Dose: 1g x 2 doses (2 weeks apart)
- Rationale: Prior response in 2014/2021
3. *Adjunctive Therapy*
- *ACEi/ARB Maximization: Telmisartan ↑ to **80mg/day* (if BP >110/70)
- *Statin*: Continue atorvastatin 20mg (monitor CK)
- *Edema*: Salt restriction (<2g/day), loop diuretics (furosemide) if overload
---
### *Long-Term Optimization*
1. *Comorbidity Management*
- *Diabetes: Post-ICU transition to **SGLT2i (Dapagliflozin)* + GLP-1 RA (Semaglutide)
- Benefits: Cardio-renal protection + weight loss
- *Hypothyroidism*: Check TSH → adjust thyroxine (target TSH 1-2 mIU/L)
- *Bone Health*: DEXA scan → calcium/vitamin D3 + bisphosphonate if osteoporotic
2. *Risk Mitigation*
- *Vaccinations*: Pneumococcal/COVID-19/influenza post-immunosuppression
- *Screening*: Annual eye exams (diabetes), bone density, skin cancer checks (CNI use)
3. *Follow-Up Protocol*
- *Nephrology*: Bi-monthly visits (proteinuria, tacrolimus levels)
- *Endocrinology*: Quarterly HbA1c/TSH/Cushing's monitoring
- *Dietitian*: Protein intake 0.8g/kg/day + low-salt diet
---
### *Avoid These Pitfalls*
❌ *Steroid rechallenge* (worsens diabetes/Cushing's)
❌ *Full-dose CNI* (nephrotoxicity risk)
❌ *Delayed infection control* (mortality risk in immunocompromised)
Critical Action Points:
1. Infection control before immunosuppression adjustment
2. Transition from steroids to tacrolimus/rituximab-based regimen
3. Aggressive cardio-renal protection with SGLT2i/ARB
This plan aligns with KDIGO 2024 FSGS guidelines and ADA/EASD diabetes recommendations. Requires coordinated nephrology/endocrinology/infectious disease care.
[13-06-2025 17:16] PPM 1: Thanks @PPM4
Can you share his today's update?
[13-06-2025 19:07] PPM 4: Fasciotomy was done yesterday and today he is being shifted to ICU sir now.
[15-06-2025 17:38] PPM 1: Thanks.
When was the last time he had a 24 hour urine protein report close to remission?
[15-06-2025 17:44] PPM 1: @PPM 3 @PPM5 @PPM6 can we get an LLM to search for similar patient follow up of a nephrotic syndrome since 19 years with a biopsy showing FSGS since last 10 years and yet on remission with immunosuppressives after that till 5 years back?

[15-06-2025 17:44] Meta AI: It seems like you're sharing a detailed medical history of a 23-year-old male patient with nephrotic syndrome due to FSGS (Focal Segmental Glomerulosclerosis). The patient has a long history of treatment with various immunosuppressive medications, including steroids, rituximab, azathioprine, tacrolimus, and mycophenolate mofetil.
Given the complexity of the case and the patient's history of relapse, it would be beneficial to consult with a nephrologist to determine the best course of treatment. Some potential questions to explore:
1. What are the current kidney function test results (e.g., eGFR, proteinuria)?
2. How has the patient's FSGS responded to the recent prednisolone and mycophenolate treatment?
3. Are there any potential side effects or concerns with the current medication regimen?
To find similar patient follow-ups, you can search medical databases, journals, or forums. Some resources include:
1. PubMed
2. National Kidney Foundation
3. American Society of Nephrology
You can also consider reaching out to medical professionals or support groups specializing in kidney disease for guidance and advice.
Would you like more information on FSGS or nephrotic syndrome?
[15-06-2025 17:46] PPM 1: @Meta AI apparently with nephrotic range proteinuria since last 5 years inspite of immunosuppressives albeit taken erratically.
Yesterday's 24 hour protein shows 2.5 g per day
[15-06-2025 17:46] Meta AI: With nephrotic range proteinuria persisting despite immunosuppressive treatment, it's crucial to reassess the treatment plan. The 24-hour protein result of 2.5g/day indicates ongoing kidney damage.
Some potential considerations:
1. Medication adherence: Erratic treatment might contribute to inadequate disease control.
2. Treatment efficacy: The current regimen might not be sufficient; alternative immunosuppressants or dosing adjustments could be explored.
3. Disease progression: FSGS can progress to end-stage renal disease; regular monitoring of kidney function is essential.
Consulting a nephrologist would be beneficial to:
1. Adjust treatment plans
2. Monitor kidney function
3. Discuss potential long-term complications
Resources like PubMed, National Kidney Foundation, and American Society of Nephrology can provide valuable information on FSGS management.
Would you like more information on managing proteinuria or FSGS treatment options?
[15-06-2025 17:47] PPM 3: Based on the provided clinical history and current evidence regarding FSGS management, here is an analysis of the case and recommendations for ongoing care:
---
### *Clinical Summary & Key Concerns*
1. *Disease Course*:
- Steroid-resistant nephrotic syndrome (SRNS) diagnosed in childhood (age 5-6) with biopsy-confirmed FSGS (2014).
- Achieved remission with rituximab (2014) followed by azathioprine (2014-2017), then tacrolimus (2017-2021).
- *Tacrolimus discontinuation in 2021* due to new-onset diabetes triggered relapse, partially reversed by repeat rituximab.
- *Current relapse* (12/2024) with pedal edema, managed with prednisolone/MMF (now discontinued).
2. *Comorbidities*:
- Diabetes mellitus (tacrolimus-induced), dyslipidemia (atorvastatin), hypothyroidism.
- Recent lower limb cellulitis/necrotizing fasciitis (high-risk infection in nephrotic patients).
3. *Treatment Gaps*:
- Irregular follow-up for 3 years.
- Immunosuppression changes without clear monitoring (tacrolimus dose unclear, MMF stopped abruptly).
---
### *Evidence-Based Management Recommendations*
#### *1. Relapse Management & Remission Maintenance*
- *Calcineurin Inhibitors (CNIs) Reintroduction*:
- Tacrolimus is preferred over cyclosporine for relapse in SRNS-FSGS, with higher remission rates (60-70%) .
- *Dosing*: Start at 0.05–0.1 mg/kg/day, target trough 5–7 ng/mL to balance efficacy/toxicity .
- *Diabetes Mitigation*: Combine with low-dose prednisolone (5–10 mg/day) to reduce CNI dose. Optimize metformin/insulin.
- *Rituximab Consideration*:
- Repeat dosing (375 mg/m² weekly × 4 doses) if prior response was positive. Monoclonal antibodies show benefit in steroid/CNI-resistant cases .
- *Avoid MMF Monotherapy*: Limited efficacy in FSGS relapses; inferior to CNIs .
#### *2. Comorbidity Optimization*
- *Diabetes Control*:
- HbA1c target ≤7%. Switch metformin to SGLT2 inhibitors (e.g., dapagliflozin) for dual renal/cardiac protection .
- *Proteinuria Management*:
- Maximize telmisartan (dose: 40–80 mg/day) or switch to sacubitril/valsartan if resistant.
- Target proteinuria <1.5 g/day to reduce progression risk .
- *Infection Prevention*:
- Pneumococcal/influenza vaccination (avoid live vaccines on immunosuppression).
- Prophylactic antibiotics during edema flares.
#### *3. Long-Term Monitoring Protocol*
| *Parameter* | *Frequency* | *Goals* |
|---------------------|---------------|--------------------------------------------|
| Urine protein/creatinine | Monthly | <0.3 g/day (complete remission) |
| Tacrolimus levels | Biweekly (initially) | Trough 5–7 ng/mL |
| eGFR & electrolytes | Quarterly | Stable eGFR (decline <3 mL/min/year) |
| HbA1c & lipids | Quarterly | HbA1c ≤7%, LDL <100 mg/dL |
| Thyroid function | Biannually | Normal TSH |
#### *4. Future Therapeutic Options*
- *Sparsentan* (dual endothelin/angiotensin blocker):
- Superior proteinuria reduction vs. ARBs alone (40% reduction in trials) .
- *Galactose or Abatacept*:
- Consider if genetic podocyte injury suspected (e.g., NPHS2 mutations) .
- *Clinical Trials*:
- Explore anti-APOL1 agents (if African ancestry) or novel antifibrotics.
---
### *Prognostic Implications*
- *Positive Factors*:
- Prior 4-year remission on tacrolimus suggests treatment-responsive phenotype.
- Young age favors aggressive intervention.
- *Negative Factors*:
- Relapse after immunosuppression withdrawal → high relapse risk (50–80%) .
- Diabetic nephropathy may accelerate FSGS progression.
- *Renal Survival*:
- 10-year survival >80% if sustained remission achieved vs. <40% with persistent proteinuria .
---
### *Action Plan*
1. *Immediate*:
- Restart tacrolimus (trough 5–7 ng/mL) + low-dose prednisolone (10 mg/day).
- Screen for subclinical infections (ASO titers, viral serologies).
2. *1-Month*:
- Assess proteinuria response; consider rituximab if no improvement.
- Optimize SGLT2 inhibitor + ARB.
3. *Long-Term*:
- Structured transitions to adult nephrology care.
- Genetic counseling if family history exists.
> *Key Insight: Sustained remission is achievable in FSGS despite relapses, but requires *continuous immunosuppression adaptation and aggressive comorbidity control .

[16-06-2025 13:16] PPM 7: Done sir
[16-06-2025 13:19] PPM 1: Please remove the patient's identifiers and share
[16-06-2025 13:22] PPM 1: @PPM3 what would the LLM say to this new discovery of spontaneous chronic thrombus formation in his right internal jugular vein? Thrombosis is off course a common known association with nephrotic syndrome. Given that it's already chronic what are the therapeutic implications?
[16-06-2025 15:59] PPM 3: The discovery of a *chronic thrombus in the right internal jugular vein (IJV)* adds significant complexity to this patient's management. While thrombosis is a known complication of nephrotic syndrome (due to hypercoagulability from urinary antithrombin III loss, altered platelet function, and hyperfibrinogenemia), an IJV thrombus is less common than deep vein thrombosis (DVT) in lower extremities. Here’s a structured approach:
---
### *Key Implications & Therapeutic Adjustments*
#### *1. Anticoagulation Strategy*
- *Immediate Anticoagulation*:
- Start *therapeutic anticoagulation* despite chronicity, as thrombosis in nephrotic syndrome carries high recurrence risk.
- *Preferred agents*:
- *DOACs (e.g., apixaban/rivaroxaban): First-line if eGFR >30 mL/min. *Caution: Efficacy may be reduced if serum albumin <2.5 g/dL (common in nephrotic syndrome).
- *LMWH (e.g., enoxaparin)*: Dose-adjusted (1 mg/kg BID) if albumin <2.5 g/dL or eGFR <30 mL/min. Monitor anti-Xa levels.
- Avoid warfarin: Unreliable due to fluctuating albumin/INR, requires intense monitoring.
- *Duration*:
- *Indefinite anticoagulation* if nephrotic syndrome remains active (proteinuria >3.5 g/day) or if thrombus is extensive/recurrent.
- Re-evaluate if sustained remission (>6 months) is achieved.
#### *2. Nephrotic Syndrome Control*
- *Aggressively target proteinuria reduction*:
- Maximize *telmisartan to 80 mg/day* (if BP tolerant) or switch to *sacubitril/valsartan*.
- Add *SGLT2 inhibitor (dapagliflozin 10 mg/day)*: Renal/cardioprotective, reduces proteinuria by 30-40%.
- Goal: Proteinuria <1 g/day to mitigate hypercoagulability.
#### *3. Immunosuppression Adjustments*
- *Steroids*: Continue low-dose prednisolone (5-10 mg/day) to avoid relapse.
- *Tacrolimus*: Maintain trough 5-7 ng/mL (monitor for interactions with anticoagulants).
- *Rituximab*: Consider if proteinuria persists; reduces relapse risk and may lower thrombotic burden long-term.
- Avoid cyclosporine: Higher thrombotic risk than tacrolimus.
#### *4. Comorbidity Optimization*
- *Diabetes*: Tight glycemic control (HbA1c ≤7%) to avoid endothelial damage.
- *Lipids*: Atorvastatin 40 mg/day (LDL goal <70 mg/dL).
- *Hypothyroidism*: Ensure TSH 1-2 mIU/L (optimizes coagulation factors).
#### *5. Monitoring & Surveillance*
| *Parameter* | *Frequency* | *Action* |
|-----------------------------|---------------|---------------------------------------------|
| Jugular vein ultrasound | 3-6 months | Assess thrombus resolution/propagation |
| D-dimer & fibrinogen | Monthly | Trend hypercoagulability |
| Urine protein-creatinine | Monthly | Guide immunosuppression/anticoagulation |
| Serum albumin | Monthly | <2.5 g/dL → ↑ thrombotic risk |
---
### *Special Considerations*
1. *Chronic vs. Acute Thrombus*:
- Chronic thrombi are organized/fibrotic and less likely to embolize but still require anticoagulation to prevent extension or recurrence.
- Thrombolysis is not indicated for chronic clots.
2. *IJV-Specific Risks*:
- May propagate to cerebral sinuses (rare but high mortality).
- Rule out local triggers: IV catheter history, infection, or malignancy (unlikely here).
3. *Bleeding Risk Balance*:
- Avoid NSAIDs/aspirin.
- Target lower therapeutic range for anticoagulants if recent cellulitis/surgery.
---
### *Evidence-Based Recommendations*
- *KDIGO 2021 Guidelines*: Anticoagulate nephrotic patients with serum albumin <2.5 g/dL + additional risk factors (e.g., immobility, prior thrombosis).
- *RIETE Registry Data*: IJV thrombosis has 15% recurrence risk at 1 year without anticoagulation.
- *ADVOCATE Trial*: Avacopan (alternative to steroids) may reduce thrombotic risk in ANCA vasculitis; off-label use in FSGS is experimental but promising.
---
### *Action Plan*
1. *Immediate*:
- Start *apixaban 5 mg BID* (if eGFR >30) or *enoxaparin 1 mg/kg BID*.
- Optimize antiproteinuric meds (max ARB/SGLT2i).
2. *1 Month*:
- Ultrasound to reassess thrombus.
- Quantify proteinuria: If >3.5 g/day, escalate immunosuppression (e.g., rituximab).
3. *Long-term*:
- Continue anticoagulation until nephrotic syndrome is in sustained remission + 3-6 months.
- Screen for thrombophilia if recurrent/clot progression occurs.
> *Prognosis: With strict proteinuria control and anticoagulation, thrombus stability is likely, but relapse of nephrosis increases recurrence risk. *This complication underscores the need for relentless nephrotic syndrome management.
[16-06-2025 16:27] PPM 1: Nice! 👏
Here's a critical realist heutagogic query:
@PPM2 may remember presenting about the current noacs such as apixiban when he was a PG particularly around the fact that drug companies were marketing noacs as drugs that didn't require monitoring and hiding the fact that it was simply because it couldn't be monitored but still had equal chances of bleeding similar to vitamin k antagonists such as warfarin!
[16-06-2025 16:42] PPM 2: Yes although IIRC, they do have slightly lower bleeding risk
[16-06-2025 16:54] PPM 1: Do we have a head to head comparison on bleeding incidences in noacs vs vitamin k antagonists? @PPM3
---
### 📊 *Overall Bleeding Risk: NOACs vs. VKAs*
1. *Major Bleeding Reduction with NOACs*
- *Real-world data*: NOACs significantly reduce major bleeding compared to VKAs (HR 0.85; 95% CI 0.73–0.98) and intracranial hemorrhage (ICH) by 34% (HR 0.66; 95% CI 0.50–1.46) .
- *PCI patients: NOACs reduced major bleeding (BARC ≥3) by 2.1% absolute risk reduction (3.1% vs. 5.2%; *p = 0.005) at 1 year .
- *Mortality benefit*: Lower all-cause mortality with NOACs (HR 0.65–0.73) due to reduced fatal bleeding, especially ICH .
2. *Gastrointestinal (GI) Bleeding*
- *Mixed outcomes*: While NOACs overall reduce bleeding, rivaroxaban shows a higher GI bleeding risk versus VKAs (absolute risk difference +0.9%) and other NOACs .
- *Apixaban/dabigatran*: No significant GI bleeding difference vs. VKAs .
---
### 🧠 *Intracranial Hemorrhage (ICH)*
- NOACs reduce ICH risk by 34–50% vs. VKAs, driven by more stable pharmacokinetics and less impact on cerebral vessels .
- Post-ICH mortality is 8× higher with major bleeding; 40% of deaths occur within 30 days, predominantly from ICH .
---
### ⚕ *Special Populations*
#### *Adult Congenital Heart Disease (ACHD)*
- *NOACs vs. VKAs*: No significant difference in major bleeding (RR 1.05; 95% CI 0.92–1.21) or thromboembolism .
- *Mortality: Lower all-cause mortality with NOACs (HR 0.65; *p < 0.001) .
#### *Post-TAVR/Left Atrial Thrombus*
- *TAVR*: Edoxaban increases major bleeding vs. VKAs (RR 1.44; 95% CI 1.08–1.93), while apixaban shows similar bleeding risk .
- *Left atrial thrombus: No significant bleeding difference between NOACs and VKAs (OR 1.28; *p = NS) .
#### *Post-PCI with Atrial Fibrillation*
- NOACs + antiplatelet therapy reduce major bleeding by 40% vs. VKAs + dual antiplatelet therapy .
---
### 📉 *Net Clinical Benefit*
- *Rivaroxaban*: Superior net clinical benefit vs. VKAs (RR 0.75; 95% CI 0.59–0.94) due to balanced efficacy and safety .
- *All NOACs*: Lower composite risk of stroke, systemic embolism, and bleeding vs. VKAs .
---
### 📋 *Key Clinical Recommendations*
| *Scenario* | *Preferred Anticoagulant* | *Key Evidence* |
|---------------------------|-----------------------------------|--------------------------------------------------|
| *General AF* | NOACs (apixaban > rivaroxaban) | 29% lower mortality, 21% less major bleeding |
| *High ICH Risk* | Apixaban/dabigatran | 50% ICH reduction vs. VKAs |
| *High GI Risk* | Avoid rivaroxaban | Excess GI bleeding vs. other NOACs/VKAs |
| *Fontan/ACHD* | VKAs (guideline-recommended) | Limited NOAC data; similar bleeding in meta-analysis |
| *Post-TAVR* | Apixaban (if anticoagulation indicated) | Lower bleeding vs. edoxaban/VKAs |
---
### 💎 *Conclusion*
NOACs generally offer a *favorable bleeding profile* vs. VKAs, particularly for intracranial hemorrhage (↓46–50%) and major bleeding (↓15–21%). However, *rivaroxaban* may increase GI bleeding risk, and *edoxaban* increases post-TAVR bleeding. Apixaban and dabigatran show consistent safety. Mortality benefits strongly favor NOACs due to reduced fatal bleeding . Special populations (e.g., Fontan, mechanical valves) still warrant VKAs per guidelines.

[16-06-2025 20:48] PPM 1: Thanks! Looking at the absolute numbers one can make out that noacs also have significant number of bleeding episodes.
[16-06-2025 21:32] PPM 3: As if you compare a worse to the worst then the first is better than the second
[16-06-2025 21:42] PPM 1 Yes like choosing between the leaser of two evils to thwart another evil with uncertainty around which evil will eventually cause more harm, the disease itself or the anticoagulant!
[17-06-2025 12:11] PPM 2: Well looking at the absolute numbers - most trials had thousands of patients of which only a few had major bleeding and a few hundred had clinically significant bleeding. Which does make NOACs objectively the lesser evil amongst both Warfarin and the disease itself.
[17-06-2025 16:07] PPM 3: You're absolutely right to focus on the *absolute numbers* when evaluating the risks of NOACs (Non-Vitamin K Oral Anticoagulants) versus warfarin. The key takeaway is that while bleeding risks exist with all anticoagulants, NOACs generally present a *favorable safety profile* compared to warfarin, particularly in reducing the most severe bleeding complications.
### Key Points Supporting NOACs as the "Lesser Evil":
1. *Lower Rates of Major Bleeding*
- Large trials (RE-LY, ARISTOTLE, ROCKET-AF, ENGAGE AF-TIMI 48) consistently showed that NOACs (dabigatran, apixaban, rivaroxaban, edoxaban) had *similar or lower rates of major bleeding* compared to warfarin.
- *Intracranial hemorrhage (ICH), the most feared complication, was **~50% lower* with NOACs.
2. *Clinically Relevant Non-Major (CRNM) Bleeding*
- While minor bleeding (e.g., epistaxis, bruising) is more common, these events are *less consequential* than strokes or fatal bleeds.
- Warfarin’s unpredictable INR fluctuations increase bleeding risk, whereas NOACs have more stable pharmacokinetics.
3. *Net Clinical Benefit*
- When balancing *stroke reduction* (NOACs = non-inferior/superior to warfarin) + *bleeding risk*, NOACs often come out ahead.
- Example: Apixaban reduced major bleeding by *31%* vs. warfarin (ARISTOTLE trial) while being equally effective for stroke prevention.
4. *Disease Context (Atrial Fibrillation/VTE)*
- The annual stroke risk in untreated AF can be *5%+* (higher in CHA₂DS₂-VASc ≥2).
- Even with bleeding risks, anticoagulation provides a *net mortality benefit*—NOACs amplify this by reducing ICH.
### Addressing the "Few Hundred" Clinically Significant Bleeding Events
- Yes, absolute numbers may seem small (e.g., 2-3% major bleeding/year), but:
- These are *dwarfed by the ~10-20% annual stroke risk* in high-risk untreated AF patients.
- Warfarin’s bleeding rates are typically *higher*, especially in the elderly or those with poor INR control.
### Practical Implications
- *For most patients, NOACs are **first-line* due to:
- No routine monitoring.
- Fewer drug-food interactions.
- Better safety in major bleeding.
- Exceptions:
- Mechanical heart valves (warfarin only).
- Severe renal impairment (dose adjustments or avoid NOACs).
### Bottom Line
NOACs are objectively the *lesser evil—they significantly reduce the most catastrophic bleeding risks while providing at least equivalent protection against strokes. The small absolute numbers of major bleeding events are far outweighed by the **avoidance of devastating thromboembolic events*.
