Jaa 58 Year Old Female Is Admitted For A Work Up For A Complaint Of Ne
Jaa, a 58-year-old female, has been admitted for a workup due to complaints of neck and low back pain. During her admission, it was discovered that she underwent a renal transplant six years prior. Laboratory findings reveal an elevated serum calcium level of 13.9 mg/dL (normal range: 8.5–10.2 mg/dL), a hematocrit of 33%, and hemoglobin level of 11.1 g/dL (normal range for adult females: 37–47% hematocrit; 12–16 g/dL hemoglobin). These findings raise concerns regarding her current health status, including potential causes related to her transplant history, and provide clues toward underlying pathology.
The elevated serum calcium, or hypercalcemia, signifies an abnormal calcium regulation which warrants detailed investigation. Hypercalcemia can result from various etiologies, such as primary hyperparathyroidism, malignancies producing parathyroid-related protein, vitamin D intoxication, certain medications, or dehydration. Given her history of kidney transplantation, this elevation could also be related to secondary complications such as tertiary hyperparathyroidism—a common sequela in chronic kidney disease—and medication effects from immunosuppressive therapy (Lumachi, 2010).
Her anemia—reflected by a hemoglobin of 11.1 g/dL and a hematocrit of 33%—further suggests a chronic disease process or potential marrow suppression. Chronic kidney disease (CKD) is a known cause of anemia, primarily owing to decreased erythropoietin production by the failing kidneys (Kimberley, 2017). Additionally, her recent history of immunosuppressant therapy raises concern for increased susceptibility to infections and secondary malignancies. Both conditions can present with anemia, and the possibility of occult bleeding, especially considering her transplant history and immunotherapy, must also be assessed.
Given her clinical presentation and laboratory findings, a comprehensive assessment should include evaluating her current immunosuppressive regimen and adherence, as persistent or new rejection episodes could contribute to her symptoms and laboratory abnormalities. Further physical examinations, focusing on signs of infection, malignancy, or paraneoplastic processes, are necessary. In terms of investigations, a detailed metabolic panel including serum albumin, phosphorus, magnesium, and PTH (parathyroid hormone) levels can elucidate the cause of hypercalcemia. A renal ultrasound can evaluate the transplanted kidney for structural abnormalities, hydronephrosis, or stones, which could explain her back pain.
Additional tests should include a urinalysis for signs of infection or stones, and possibly advanced imaging like a non-contrast CT scan of the abdomen and pelvis to identify nephrolithiasis or other calcifications. Assessing her bone mineral density through a DEXA scan is relevant, especially considering her age and chronic illness, which predispose her to osteoporosis. Given the elevated calcium and anemia, screening for malignancies such as multiple myeloma or metastatic disease is advisable, including serum protein electrophoresis, immunofixation, and possibly a bone marrow biopsy if indicated. Evaluation of her PTH level will help determine if the hypercalcemia is due to primary hyperparathyroidism—an often overlooked cause in post-renal transplant patients.
Overall, management will involve addressing the underlying cause of hypercalcemia, whether it be parathyroid hyperactivity, malignancy, or dehydration. Careful adjustment and monitoring of her immunosuppressive therapy are imperative to minimize risks of rejection and secondary complications. Moreover, addressing her anemia might involve erythropoiesis-stimulating agents or iron supplementation, depending on further lab results. Ensuring adequate hydration and electrolyte balance is fundamental, especially if dehydration is suspected.
In conclusion, her current presentation is likely multifactorial, involving transplant-related metabolic disturbances, potential secondary hyperparathyroidism, possible malignancy, and common post-transplant complications like osteoporosis and anemia. A multidisciplinary approach, incorporating nephrology, endocrinology, and oncology expertise, is essential. Close follow-up and tailored treatment addressing each aspect of her illness are crucial to improve her outcomes and alleviate her symptoms.

Renal transplantation offers significant benefits for patients with end-stage renal disease; however, long-term management remains complex due to numerous potential complications. This case of a 58-year-old woman presenting with hypercalcemia, anemia, and localized back pain underscores the importance of comprehensive evaluation in post-transplant patients. Her laboratory findings—elevated serum calcium, decreased hematocrit, and hemoglobin—are indicative of underlying pathologies that require targeted investigations and interventions.
Understanding the Pathophysiology of Hypercalcemia in Post-Transplant Patients
Hypercalcemia is a common metabolic disturbance in patients with chronic kidney disease and after renal transplantation (Lumachi, 2010). It can often be attributed to secondary hyperparathyroidism—a compensatory response to decreased renal function and disturbances in calcium-phosphate homeostasis (Bhadada et al., 2012). Over time, persistent stimulation of the parathyroid glands may lead to tertiary hyperparathyroidism, resulting in autonomous PTH secretion and calcium mobilization from bones. Additionally, certain medications such as vitamin D analogs and calcium-based phosphate binders used in transplant patients can elevate serum calcium levels (Kimberley, 2017).
Anemia in Post-Transplant Patients: Etiologies and Diagnostic Approaches
The anemia observed with a hematocrit of 33% and hemoglobin of 11.1 g/dL in this patient is commonly seen in post-transplant populations. Chronic kidney disease directly affects erythropoietin synthesis, leading to anemia (Kimberley, 2017). Iron deficiency, nutritional deficiencies, infections, and adverse effects of immunosuppressive drugs such as azathioprine and mycophenolate mofetil can further compound this issue. Malignancies, particularly post-transplant lymphoproliferative disorders or other secondary cancers, also represent significant causes, especially given her immunosuppressed state (Syang et al., 2019).
Clinical and Laboratory Evaluation Strategies
Key assessments should include measuring serum parathyroid hormone (PTH) levels to confirm secondary or tertiary hyperparathyroidism, which is frequently encountered in this demographic (Bhadada et al., 2012). Evaluating her renal function through serum creatinine and estimated glomerular filtration rate (eGFR) will clarify whether renal deterioration contributes to her metabolic derangements. Imaging, particularly renal ultrasonography, can detect structural abnormalities or stones causing her back pain, which may also contribute to her symptoms (Eknoyan et al., 2019).
Further, comprehensive evaluation for secondary causes of anemia, including iron studies, vitamin B12 levels, and assessment for occult bleeding, should be performed. Bone mineral density testing can identify osteoporosis, which is prevalent among transplant recipients due to steroid use and metabolic disturbances (Wang et al., 2018). Malignancy screening should include serum protein electrophoresis, imaging studies such as CT scans, and possibly biopsy procedures if needed. Monitoring her medication adherence and side effects, particularly immunosuppressants, is essential for holistic care (Syang et al., 2019).
Management and Follow-up Considerations
The management of her hypercalcemia involves treating its root causes, such as controlling secondary hyperparathyroidism with calcimimetics (e.g., cinacalcet) or parathyroidectomy if indicated. Hydration and bisphosphonates may be useful if significant bone resorption is present. Adjusting her immunosuppressive therapy might be necessary if medication side effects contribute to her condition. Addressing anemia could involve erythropoiesis-stimulating agents and iron supplementation, with regular monitoring of blood counts and iron parameters.
Addressing her back pain should involve ruling out nephrolithiasis, degenerative disc disease, or other musculoskeletal issues. Ensuring adequate hydration to prevent stone formation and maintain renal perfusion is beneficial. Collaborative care with nephrology, endocrinology, and oncology specialists can optimize her outcomes.
In summary, her presentation highlights the complex interplay between transplant-related metabolic disturbances, medication effects, and long-term complications such as secondary hyperparathyroidism and anemia. Proactive, multidisciplinary management is essential in improving her quality of life and preventing further adverse outcomes related to her transplant history.
