Chronic lymphocytic leukaemia (CLL) occurs rarely with pregnancy and monoclonal B-Lymphocytosis (MBL) has not previously been described in this setting. CLL is predominantly a disease of the elderly and affects men twice as often as women and hence only an estimated 2% of patients are females of childbearing age. We identified only five reported cases of CLL in pregnancy in the literature. We describe two additional cases, plus three other women with CLL dealing with pregnancy-related decisions. We review the literature and discuss proposals for management and issues that arise in this relatively uncommon occurrence. In contrast to many other haematological malignancies where longer remissions are typically associated with a lower risk of relapse, most patients with CLL who require treatment will ultimately relapse with current therapy. This complex setting requires careful consideration and well informed patients to assist with decisions related to pregnancy. © 2014 John Wiley & Sons Ltd. Source

Hypogammaglobulinemia is a common complication of chronic lymphocytic leukemia (CLL), but the significance of immunoglobulin G (IgG) subclass deficiency is unknown. We analyzed the prevalence of immunoglobulins G, A and M, IgG subclass deficiency and infection in 150 patients with CLL. Low IgG, IgA and IgM levels were observed in 27.3%, 30.7% and 56.7% of patients, respectively. IgG subclass deficiency was frequent, with reduced IgG1, IgG2, IgG3 and IgG4 in 28%, 19.3%, 52% and 22.7% of patients, respectively. IgG subclass deficiency (total 64.6%) and hypogammaglobulinemia (27.3%) were more prevalent than clinically significant infection (16%). Recurrent or significant infections were seen in 24 patients (16%), of whom 50% had hypogammaglobulinemia but 100% had at least one IgG subclass deficiency, indicating that half the patients with infection had IgG subclass deficiency but normal total IgG level. Deficiencies of IgG3 and IgG4 were statistically associated with infection risk. Normal immunoglobulin and IgG subclass levels were seen in 26 patients (17%) and none had infections. IgG subclass deficiency is commonly observed in patients with CLL with both normal and reduced total IgG levels, and is associated with infection. Screening patients with CLL for IgG subclass deficiency may be a useful adjunct in stratifying their infection risk. © 2013 Informa UK, Ltd. Source
