[Antirheumatic therapy and reproduction. The influence on fertility, pregnancy and breast feeding]

Antirheumatic drugs can have a negative effect on reproduction in both men and women. Possible negative effects are impairment of fertility, harmful effects on the fetus and adverse effects on the breastfed child. In women non-steroidal antiinflammatory drugs (NSAID) and cyclophosphamide can impair fertility. In men infertility can result from the use of salazopyrine and cyclophosphamide. A desire for children should be taken into account before the start of disease modifying drugs (DMARD). Treatment with NSAID is possible at some stages of pregnancy as well as during lactation. A limited number of DMARD is compatible with pregnancy and is presented. Cytostatic drugs and leflunomide must be prophylactically withdrawn before a planned pregnancy. TNF alpha antagonists should be discontinued at the start of pregnancy. Safe birth control must be practised during therapy with drugs that are gonadotoxic or teratogenic. Treatment with immunosuppressive drugs during lactation is limited because of insufficient documentation of safety for the breastfed child.

Management of RA medications in pregnant patients

A desire for children or the presence of pregnancy limits the drug therapy options for a woman with rheumatoid arthritis. Combination therapies that include methotrexate or new drugs that have not been studied or used in pregnant patients must be excluded, even though they might be highly efficacious. With few exceptions, the reason for this exclusion is not the proven teratogenicity of the drugs, but the absence of proven safety for the fetus. Whereas methotrexate, leflunomide, abatacept and rituximab must be withdrawn before a planned pregnancy, tumor necrosis factor inhibitors and bisphosphonates can be continued until conception. Antimalarial agents, sulfasalazine, azathioprine and ciclosporin are compatible with pregnancy, and so can be administered until birth. Corticosteroids and analgesics such as paracetamol (acetaminophen) can also be used throughout pregnancy. NSAIDs can be safely administered until gestational week 32. The most important consideration when managing rheumatoid arthritis medications during pregnancy is that therapy must be tailored for the individual patient according to disease activity.

Combination therapy for multidrug-resistant cytomegalovirus disease

Multidrug-resistant (MDR) cytomegalovirus (CMV) emerged after transient responses to ganciclovir, foscarnet, and cidofovir in a CMV-seropositive recipient who underwent allogeneic hematopoietic stem cell transplantation from a CMV-seronegative donor. Experimental treatments using leflunomide and artesunate failed. Re-transplantation from a CMV-seropositive donor supported by adoptive transfer of pp65-specific T cells and maribavir was followed by lasting suppression. This case illustrates that successful MDR CMV therapy may require individualized multidisciplinary approaches. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Changes in use of disease-modifying anti-rheumatic drugs in Australia over the period 1992-2004

Purpose Evidence is growing that early use of disease-modifying anti-rheumatic drugs (DMARDs) and combinations of these drugs provide optimal care for people with rheumatoid arthirits. The aim of this study was to describe objectively the pattern of consumption of DMARDs in the Australian community (community-based prescribing, specialist and general practitioner) 1992-2004, and to compare this with prescribing patterns reported in other countries. Method Dispensing statistics from the Pharmaceutical Benefit Scheme (PBS-Australia's universal prescription subsidy scheme) were analysed and temporal trends evaluated. Drug consumption was calculated as the number of dispensed defined daily doses (DDD)/1000 inhabitants/day (WHO ATC/DDD classification 2005). Results The consumption of DMARDs in the Australian community increased steadily from 2.6 DDD/1000 inhabitants/ day in 1992 to 5.5 DDD/1000 inhabitants/day. Over the period 1992-2004, methotrexate (MTX) was the most commonly used DMARD (from 0.6 to 3.0 DDD/1000 inhabitants/day). Consumption of gold (parentcral and oral) and penicillamine declined during this time. The inclusion of leflunomide on the PBS in 2000 contributed to the increase in DMARD usage. Conclusion Use of DMARDs within the Australian community has increased in recent years, coinciding with the change in guidelines for therapy for rheumatoid arthritis (RA) to earlier use of DMARDs and the more common use of combinations. This study used DDD methodology to quantify trends for DMARD consumption and these trends are broadly consistent with international prescribing patterns assessed using different methodologies.
