The aim of this study was to assess the presence of Chlamydia pneumoniae antibodies in patients with angiographically verified atherosclerotic coronary artery disease. A total of 114 consecutive patients were investigated between April 1995 and June 1996. Patients were divided into two groups: 72 patients with acute myocardial infarction (AMI; 53 men, 19 women, mean age 62.27 +/- 10.1 years), and 42 patients with chronic ischemic heart disease (CAD; 37 men, 5 women, mean age 62.75 +/- 9.2 years). A control group of 50 normal subjects matched for age (mean 62 +/- 9 years), sex, social status and geographical area was used. Identification of Chlamydia pneumoniae was carried out with the microimmunofluorescence method, on two serum samples taken from patients on admission and after 15 days. The IgM, IgG and IgA anti-Chlamydia pneumoniae titers were assessed, values > or = 1:16, > or = 1:32 and > or = 1:8 being respectively considered positive. Acute (IgM > or = 16 or four fold rise of IgG titer) and chronic (IgG > or = 128 e IgA > or = 32 or only elevated IgA titer) infections were analyzed. IgM antibodies were not found in AMI, CAD and control groups. IgG positivity (IgG > or = 32) was found in 38% of the control group, in 58.3% of the AMI group (p < 0.05) and 42.8% of the CAD group (p < 0.01). IgA positivity > or = 8) was found in 22% of the control group, in 31.9% of the AMI group (NS) and in 33.3% of the CAD group (p < or = 0.05). Acute infection was observed in 5.5% of AMI patients and in 12% of CAD patients (NS), whereas no subject of the control group showed these values. Chronic infection was observed in 9.7% of AMI patients and in 16.6% of CAD patients (NS) whereas nobody of the control group showed these values. In conclusion, our results suggest that Chlamydia pneumoniae infection is present only in the AMI and CAD groups. It is possible to suppose that this infection may be linked to atherosclerosis through an endothelial damage or a systemic endogenous procoagulant and inflammatory activity.

Plasma inflammatory markers have been shown to be predictors for cardiovascular risk, however, there is no study where the levels of plasma circulatory markers have been evaluated in coronary artery disease patients (CAD pts) positive for C. pneumoniae IgA and high sensitive C-reactive protein (hsCRP) which may help in better understanding of disease pathogenesis. A total of 192 patients and 192 controls attending the Cardiology Outpatient Department of Safdarjung Hospital were enrolled. The levels of plasma circulatory inflammatory markers were evaluated by ELISA. The levels of circulatory plasma markers (IL-4, IL-8, IL-13, ICAM-1, and VCAM-1) were significantly higher, whereas, levels of IL-10 and IFN-gamma were significantly lower in CAD pts compared to healthy controls. The levels of IL-4, IL-8, and ICAM-1 (P = .007, .015, and .048) were significantly higher, however, IL-10 and IFN-gamma were significantly lower (P < .001, < .001) in C. pneumoniae IgA positive CAD pts. The levels of IL-4, IL-8, IL-13, ICAM-1, and VCAM-1 were higher but not significant and levels of IL-10 and IFN-gamma were significantly (P < .001, < .001) lower in hsCRP positive CAD pts. Our study suggested that circulatory cytokines, namely, IL-4, IL-8, and adhesive molecules like ICAM-1 were enhanced after infection with C. pneumoniae whereas in contrast to this IL-10 and IFN-lambda were lowered. Suggesting the important role of these cytokines in progression of CAD.

IgA pemphigus, resembling subcorneal pustulous dermatosis, represents a rare complication of IgA type monoclonal gammopathy. The patient dates the onset of initial symptoms of vesicular-bullous disease to 1990. She was first examined at our clinic in 2001 with the following conclusion "type IgA monoclonal gammopathy of unknown significance". The first immunosuppressive treatment of vesicular-bullous disorder was administered in 2003 (dexamethasone 20 mg on days 1-4 and 15-18 in monthly cycles + daily cyclophosphamide 50 mg). Cyclophosphamide was administered for 6 months in total and dexamethasone for further 3 months. During the treatment, intensity of the skin disorder ameliorated and monoclonal IgA levels decreased to non-detectable levels. Nevertheless, skin symptoms recurred immediately after dexamethasone treatment in its original intensity was terminated, even though the concentration of monoclonal immunoglobulin IgA remained below the sensitivity of quantitative detection for further 6 months (positive immunofixation only). Six rituximab 600 mg infusions were administered in a weekly interval after stopping cyclophosphamide and dexamethasone to prevent early recurrence of skin symptoms but this treatment was without any lasting effect. Transformation into multiple myeloma was identified in 2007. First line treatment (cyclophosphamide, adriamycin and dexamethasone - CAD) remained without any haematological or dermatological treatment response. Second line treatment (thalidomide, cyclophosphamide and dexamethasone - CTD) brought about significant deterioration of skin symptoms up to the clinical picture of erythrodermia. Third line treatment (bortezomib 1.3 mg/sqm i.v. on days 1,4, 8 and 15, cyclophosphamide 50 mg daily and dexamethasone 20 mg on days 1-4 and 15-18 in 28-day cycles - VCD) resulted in rapid decline in monoclonal immunoglobulin IgA concentrations immediately following the first cycle and to negative immunofixation after 5 cycles. In total, six VCD cycles were administered. The patient has had no skin symptoms from the third cycle of this treatment and complete skin and haematological remission has been maintained for 12 months after completion of bortezomib-containing treatment. Combined treatment containing bortezomib has proven useful in the treatment of IgA pemphigus accompanying monoclonal gammopathy of uncertain significance transformed into multiple myeloma.
