ABSTRACT

Background: Diagnosis of AL amyloidosis requires demonstration of amyloid in affected tissues along with clonal plasma cells in bone marrow or presence of monoclonal light chains in blood. With increasing awareness among physicians and availability of proper diagnostics, more cases of AL amyloidosis are being diagnosed. Here we present our experience of AL amyloidosis diagnosis and treatment in the era of modern diagnostics and therapy with novel agents. Aims: We aimed to describe the clinical presentations, laboratory features and outcomes of patients with AL amyloidosis in a single center using standard diagnostic tests and treatment with novel agents. Methods: A retrospective analysis of AL amyloidosis patients, diagnosed in our hospital, a tertiary care center in India from January 2016 to December 2021. The data was collected from departmental database. All statistical analyses were done by SPSS version 17. Results: Diagnosis of AL amyloidosis was done in 27 patients. Median age of presentation was 59 years. 22 (81.5%) were males. Major symptoms were pedal edema (37%), shortness of breath (22.2%), frothy urine (11.1%) and fatigue (11.1%). Twenty two (81.5%) presented with ECOG PS ≥ 2. Most common system involved was renal in 16 (59.2%), followed by cardiac in 13 (48.1%) and gastro-intestinal in 9 (33.3%). Fifteen (55.6%) had two or more system involvement while 12 (44.4%) had single system involvement. Lambda monoclonal light chain was present in 22/27 (81.5%) and kappa monoclonal light chain was present in 5/27 (18.5%). Median Hb was 11.6 g/dl (range 6.7- 14.8 g/dl), median M-protein was 0.69 g/dL (range 0-2 g/dL) and median bone marrow plasma cells were 7% (range- 1-18%). Fourteen patients were treated;cyclophosphamide, bortezomib and dexamethasone (CyBORD) in 10/14 (71.4%) and bortezomib + dexamethasone in 4/14 (28.6%). Among 14 patients followed up with median follow up of 13 months (range 6-60 months), 5 expired;3 due to COVID, one due to cardiac arrhythmia (during first cycle) and one due to relapse and rest 9 were alive. Among the 9 patients who were alive 6 were in complete hematological response and 3 were in partial response after 6 cycles of therapy. Summary/Conclusion: Our study presents the spectrum of clinical manifestations, management and outcomes of primary amyloidosis in Indian context. There is a need to increase the awareness among the physicians about amyloidosis so that early diagnosis can be made and timely treatment can be done with novel agents to improve the dismal historical results.

ABSTRACT

Introduction: A reduced absolute lymphocyte count in peripheralblood along with relative increase in neutrophil count has beenobserved consistently in hospitalized COVID-19 patients. The role ofbaseline lymphocyte subsets in COVID-19 is still unknown.Aims &Objectives: We aimed at analyzing the baseline lymphocytesubsets in COVID-19 patients and its impact on the outcome andseverity of the disease.Materials &Methods: Study was conducted retrospectively fromhospital electronic records. Diagnosis of COVID-19 disease wasbased on the RTPCR for SARS-COV-2 virus. Lymphocyte subsetswere determined using flowcytometry in COVID-19 patients onadmission to COVID ward. The variation in the baseline lymphocytesubsets according to the severity and outcome of the disease wasanalyzed.Result: Patients who died of COVID-19 disease had higher mean Blymphocytes and NK cells than the survivors but was not statisticallysignificant. T lymphocyte counts and CD8 + T cell counts showedstatistically significant (p< 0.05) reduction in patients who expiredthan who survived COVID-19 disease.Conclusions: We concluded that low CD8 + T cell counts atadmission may be predictive of patient outcomes in COVID-19.
