Objective To estimate the therapeutic value of plasma exchange (PE) in severe bullous dermatoses and drug eruption. Methods Plasma exchange was carried out to treat 47 patients with severe dermatoses including 15 cases of pemphigus, 17 cases of bullous pemphigoid and 15 cases of drug eruption who were intolerant or unresponsive to glucocorticosteroids and or immunosuppressants. Cobe Spectra blood cell separator was utilized to collect plasma and cell components from patients' blood, and the replacement fluid and cell components were infused back into patients. Patients received 1 to 3 sessions of plasma exchange. Results Of the 47 patients, 44 (93.62%) achieved satisfactory efficacy with relief of clinical symptoms and improvement of laboratory parameters 2 to 3 days after the plasma exchange. Side effects occurred in 11 (23.4%) patients, which included fever, shivering, numbness of limbs, pruritus and convulsion. Conclusion Plasma exchange is beneficial for the control of severe drug eruption and bullous dermatoses.

Objective:
To improve the understanding of the rare clinical presentation and management of purpura fulminans (PF) in patients with paroxysmal nocturnal haemoglobinuria (PNH).
Methods:
A case of PF occurring in PNH is reported, while the related literature review is conducted.
Results:
A 49-year-old male patient suffered from one-week history of fever, greenish-brown colour urine, multiple well demarcated and painful purpura of the head and neck. He had been reported to have two thromboembolic events during the 22-year course of PNH. Skin biopsy displayed classic PF features. Laboratory testing showed a high PNH clone, intravascular hemolysis and coagulation system changes. After sufficient anticoagulation and short course of glucocorticoid therapy, the clinical conditions were improved correspondingly. During a follow-up period of 6 month, there was no recurrence of thrombosis.
Conclusion
PF should be considered in PNH patients with unexplained, quickly developed painful purpura. Extensive work-up should be performed to find out other potential thrombophilic risk factors after diagnosis of PF. Early diagnosis, adequate anticoagulation therapy and control hemolysis were essential to PF treatment occurring in PNH. The survival of patients and the qualities of life can be improved. The PNH clone detection is needed to evaluate the status of procoagulation and predict the risk of recurrent thrombosis.

Objective:To analyze the efficacy of second-line regimens and prognostic factors in patients with first-relapsed multiple myeloma (MM) treated with bortezomib, cyclophosphamide, and dexamethasone (BCD).Methods:A retrospective cohort study. Clinical data were collected in first-relapsed MM patients after BCD treatment from three tertiary hospitals in north China from July 2009 to October 2022. Patients were classified according to the second-line regimen into the immunotherapy group, single novel agent group [either proteasome inhibitor (PI) or immunomodulatory drug (IMiD)], combination treatment group (both PI+IMiD), and traditional treatment group. Responses to second-line regimens and survival data were analyzed. The Kaplan-Meier method was used for survival analysis and the Cox proportional risk model was used for univariate and multivariate analyses.Results:A total of 217 patients were enrolled including 8.8% (19/217) in the immunotherapy group, 48.4% (105/217) in the PI/IMiD group, 29.9% (65/217) in the PI+IMiD group, and 12.9% (28/217) in the traditional treatment group. The median age was 62 years (range 31-83 years) and 56.2% (122/217) were males. The overall response rates (ORRs) in the four groups were 94.7% (18/19) vs. 56.2% (59/105) vs. 73.8% (48/65) vs. 32.1% (9/28) ( χ2=24.55; P<0.001), respectively. The progression-free survival (PFS) of the second-line regimens (2ndPFS) was 17.7 vs. 9.0 vs. 9.2 vs. 4.6 months ( χ2=22.74; P<0.001), respectively, among which patients in the PI/IMiD and PI+IMiD groups had comparable 2ndPFS ( χ2=1.76; P=0.923). Patients with high-risk cytogenetic abnormalities (HRCAs) achieved the longest 2ndPFS of 22.0 months in the immunotherapy group ( χ2=15.03; P=0.002). Multivariate analysis suggested that immunotherapy ( HR=0.11, 95% CI 0.05-0.27), achievement of efficacy of partial response or better ( HR=0.47, 95% CI 0.34-0.66), and non-aggressive relapse ( HR=0.25, 95% CI 0.17-0.37) were independent prognostic factors of 2ndPFS. Conclusion:In this real-world study, immunotherapy was associated with a more favorable efficacy and PFS for first-relapsed MM patients after BCD treatment, with similar outcomes in patients with HRCAs.

Objective:
To Evaluate the efficacy and safety of posaconazole as primary prevention of invasive fungal disease (IFD) in patients with severe aplastic anemia (SAA) treated with anti-thymus/lymphocyte immunoglobulin (ATG/ALG) combined with cyclosporine intensive immunosuppressive therapy (IST).
Methods:
A retrospective analysis of clinical data of 58 SAA patients who received IST of anti-thymocyte immunoglobulin combining cyclosporine and antifungal prophylaxis during April 2013 to May 2017 in Peking Union Medical College Hospital was performed. The patients were divided into posaconazole prophylaxis group and the control group (itraconazole or fluconazole). The disease characteristics, IFD prevention effect and adverse drug reaction, curative effect and prognosis of the two groups were compared.
Results:
Posaconazole was used to prevent fungal infection in 20 patients. The other 38 patients were used as the control group. Retrospective analysis showed comparable characteristics (gender, age, disease severity, etiology, interval between the onset of disease to treatment, ATG/ALG type) of both groups. The incidence of IFD were 0 and 15.8% in posaconazole prophylaxis group and the control group, respectively (

The skin manifestations of monoclonal(M)-proteinemia are rare and present in patients with monoclonal gammopathy of undetermined significance (MGUS), smoldering plasma cell myeloma (SMM) and multiple myeloma (MM). In this study, we reported 4 cases with M-proteinemia-related rare skin lesions, including pyoderma gangrenosum (PG), erythema elevatum diutinum (EED), cutis laxa (CL) and lichen myxedematosus(LM). These skin lesions are specific, where the potential mechanism was immune-mediated paraneoplastic syndrome rather than direct plasma cell infiltration. Anti-plasma cell treatment was effective in treating skin lesions. The clinical outcome of MM-related skin changes was correlated to tumor control, whereas the prognosis of MGUS or SMM related skin lesions was favorable. Skin involvement in M-proteinemia is extremely rare and less well-known, which greatly impairs quality of life. The diagnosis and treatment of these 4 cases support the need for futher study.
