A Study of Clinical Profile and Treatment in Adult Hemophilia Patients with Special Reference to the Inhibitor Levels.

Abstract

Introduction Hemophilia is an uncommon, X-linked recessive bleeding condition characterized by a lack of either factor VIII or factor IX. It is more prevalent in men. Due to the substantial impact inhibitor development has on patient prognosis, the primary treatment for hemophilia is the transfusion of recombinant factors. The aim of our study is to investigate 40 adult patients with hemophilia in terms of their clinical profile, clinically relevant risk factors for inhibitor development, therapy-related aspects such as treatment duration, factor requirements, transfusion frequency, presence of inhibitors, and complications. Methods Thiscross-sectional observational study involving 40patients ofhemophilia over 12 years of age was conducted at a tertiary care hospital in Gujarat. Data on sociodemographic characteristics, presenting complaints, bleeding episodes, hemophilia type, and medical history were gathered over a one-year span. Patients were stratified into mild, moderate, and severe groups based on their respective levels of factor activity. Various parameters, including the frequency of factor therapy, percentage of factor concentrate, inhibitor presence, and disease and therapy-related complications, were analyzed. The distribution of patients across these parameters was calculated and illustrated using pie charts. Results Nineteen out of 40 patients were from 20 to 40 years of age. The majority of cases (n=24), however, had been diagnosed before the patients reached the age of 10. All patients were male, and half of the patients (n=20) suffered from mild disease. The most common site of bleeding was the knee joint, and 33 cases had one to 10 bleeding episodes per year. Thirty-twoout of 40 patients needed less than 40 factor vial transfusions, whereaseight needed more than 40 factor vial transfusions. Two cases of severe disease were positive for inhibitors of factor VIII, whereas one patient was found to have a hepatitis B virus (HBV) infection. Conclusions Hemophilia, a rare bleeding disorder, has primarily been studied in pediatric populations. This study, however, shifts the focus toward adult individuals. Our cohort consisted exclusively of male patients, with the predominant group diagnosed with hemophilia A and falling within the age range of 20 to 40 years. Most patients had been diagnosed before 10 years of age. The primary complication observed was joint bleeding, with the knee joint being the most commonly affected site. Approximately two-thirds of cases had a history of minor trauma necessitating factor replacement, yet only 5% exhibited the presence of inhibitors.
