Summary
Henoch-Schoenlein purpura (HSP) is a rare skin condition that can occur after kidney transplants. This case highlights HSP recurrence following IgA nephropathy, emphasizing the need for careful diagnosis and management in transplant patients.
Area of Science:
- Nephrology
- Immunology
- Dermatology
Background:
- Cutaneous vasculitis is an uncommon post-renal transplant complication with a wide differential diagnosis.
- New-onset skin rashes in transplant recipients necessitate thorough investigation.
Observation:
- A 69-year-old male renal transplant recipient presented with palpable purpura, skin ulcerations, and arthralgias.
- The patient had a history of isolated immunoglobulin A (IgA) nephropathy and was on maintenance immunosuppression.
- Skin biopsy confirmed Henoch-Schoenlein purpura (HSP), and renal biopsy revealed recurrent IgA nephropathy.
Findings:
- This is the first reported case of Henoch-Schoenlein purpura (HSP) manifesting after renal transplantation for IgA nephropathy.
- The patient's HSP developed under tacrolimus and mycophenolate mofetil immunosuppression.
- Recurrent IgA nephropathy was confirmed with IgA deposition in the renal biopsy.
Implications:
- Highlights the importance of considering HSP in the differential diagnosis of cutaneous vasculitis post-renal transplantation.
- Discusses the recurrence of IgA nephropathy and HSP in the context of renal transplantation.
- Suggests potential strategies for prevention and therapeutic management of recurrent disease.

01:26Kidney Transplant II: Surgical Procedure
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
01:28Kidney Transplant I: Introduction
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

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...
01:29Acute Kidney Injury III: Clinical Manifestations
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
01:22Acute Kidney Injury I: Introduction
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
