An ayurvedic evaluation & treatment of multiple myeloma: A case report

This case report discusses the management of multiple myeloma in a 59-year-old male patient through an integrative approach of Ayurvedic and conventional medical care. The patient presented with symptoms of pain in ribs, fatigue, nausea, weight loss, and mental stress. After undergoing chemotherapy and steroid therapy, the patient opted for Ayurvedic treatment instead of a recommended bone marrow transplant. Ayurvedic examination revealed imbalances in Vata and Pitta doshas, affecting various body tissues and mental state. The Ayurvedic regimen led to the recovery of the patient without adverse effects. This case highlights the role of Ayurvedic medication in managing multiple myeloma, warranting further research and clinical trials for broader validation.

Multiple Facets of Multiple Myeloma in Kidney Biopsy: A Multicenter Retrospective Study

Introduction

Multiple myeloma is a type of plasma cell dyscrasia, which causes clonal proliferation of plasma cells and deposition in various organ systems. At presentation, 50% of patients with multiple myeloma have kidney dysfunction, which is considered a poor prognostic indicator. Data on the histopathological manifestations of multiple myeloma are sparse.

Objective

To look at the kidney histopathological lesions in patients with the clinical diagnosis of multiple myeloma.

Materials and Methods

A retrospective analysis of all kidney biopsies in patients with the clinical diagnosis of multiple myeloma was performed from June 1, 2020 to May 30, 2022, from three tertiary care nephrology referral centers.

Results

A total of 61 patients with multiple myeloma and biopsy-proven kidney involvement were included in the study. The mean age at presentation was 55.39 ± 11.91 years, with male predominance (male to female ratio -1.6:1). The most common lesion on kidney biopsy was myeloma cast nephropathy (72.1%), followed by light chain deposition disease (21.3%) and AL amyloidosis (18%). About 26% of patients had dual lesions on kidney biopsy, 3% had three types of lesions on kidney biopsy In 48% of patients, the diagnosis of multiple myeloma was made only after the kidney biopsy.

Conclusion

Patients with multiple myeloma and kidney involvement should be biopsied as the type of histopathological lesion influences the treatment options and prognosis.

Light Chain Glomerulopathy Causing Kidney Failure in Renal Cell Carcinoma

Light chain deposition disease (LCDD) is a rare cause of kidney failure. It is associated with multiple myeloma and is diagnosed by the evaluation of serum and urine free light chains. Patients who are diagnosed with this disease often develop rapidly progressive renal failure. To our knowledge, it does not have any association with other malignancies aside from multiple myeloma. We present a case that highlights a novel association between renal cell carcinoma and light chain-mediated renal disease. Our patient was admitted due to acute renal failure and underwent a comprehensive diagnostic evaluation with an eventual diagnosis of light chain glomerulopathy in the setting of metastatic renal cell carcinoma.
