In patients with severe osteoporosis, history of retinal artery occlusion, and hypercalciuria, would you favor PTH analogue therapy or Evenity?
Assuming that PTH and vitamin D are normal, neither. Chlorthalidone is the treatment of choice in this scenario. Chlorthalidone is usually better than HCTZ, as HCTZ often must be given BID, whereas chlorthalidone can be given daily. I have seen very large improvements in BMD with thiazide therapy, o...
Is a history of Zoster ophthalmicus a contraindication to starting upadacitinib?
A history of HZO (herpes zoster ophthalmicus) or herpes zoster in any dermatome is a relative contraindication to the use of upadacitinib or any JAK inhibitor. HZO is often a very unpleasant disease with pain, ocular discomfort, and vision loss, so the chance of reactivation should be minimized. The...
How do you interpret treatment response in the DISCOVER-2 Trial when patients were allowed to remain on up to 10mg of prednisone equivalent for disease control while on guselkumab?
If patients were on less than or equal to prednisone 10 mg, they could continue that in the background during the trial, but note that only 20% of patients were on prednisone, a much lower figure than a typical rheumatoid arthritis trial, which is consistent with the point that rheumatologists shy a...
How would you approach immunosuppression in a patient with well-controlled HIV and RF+ rheumatoid arthritis breaking through hydroxychloroquine with ongoing inflammation confirmed on ultrasound?
The Infectious Disease Society of America (IDSA) defines HIV viral suppression as a viral load that is persistently below the level of quantification or detection of the assay used to measure the viral load. Prevention of sexual transmission is thought to occur at levels less than 200 copies of viru...
In light of promising results of hydroxychloroquine in COVID-19, should we consider using it prophylactically in cancer patients, especially if immunocompromised?
At this time, as there is no good evidence available, I would not recommend the use of hydroxycholoroquine prophylactically in cancer patients. It is unclear whether it would prevent contagion, probably not, and we still don't know if it will have any effect on the course of COVID-19. We expect ther...
How do you treat nocturnal leg cramps?
Nocturnal leg cramps are similar to daytime leg cramps, but stretching may be less convenient to use as a remedy, as sleep can be further disrupted. Treating and preventing leg cramps typically utilizes some combination of hydration and electrolytes but sometimes, medications can help. Consider the ...
For patients with definite UIP and MPO-ANCA-associated vasculitis limited to the lungs (without systemic manifestations), what is the role of immunosuppression?
I think in these subjects (as opposed to UIP in RA), immune suppression would be my first agent. The data are limited; there is some suggestion on biopsy that they have significant inflammation (Arnold et al., PMID 38574743). I would start with immunosuppression and have a low threshold to add anti-...
How do you screen rheumatoid arthritis patients for lung disease (modality, frequency, patient selection)?
Theoretically, we are supposed to screen these patients obtaining a baseline chest X-ray before starting DMARD therapy. As I remember, these guidelines were formulated when MTX was still blamed for MTX lung disease although presently, even the presence of underlying ILD is not necessarily a contrain...
What factors would encourage you to choose abatacept vs tocilizumab in a patient with RA-ILD with a UIP pattern of pulmonary fibrosis?
The available literature on abatacept and tocilizumab in RA-ILD does not provide a definitive answer and hopefully with the general increase in interest in ILD we will have more definitive data in the near future. My review of the current literature suggests that abatacept has a slightly higher perc...
What would be the clinical role of SGLT-2 inhibitors for lupus nephritis given it has an indication for proteinuria related to CKD?
The benefit for SGLT-2 inhibitors at slowing the progression of kidney disease or death from cardiovascular causes had been well established in patients with diabetic nephropathy. Further studies continued to demonstrate benefit in non-diabetic, proteinuric kidney disease (HR, 0.72 (95% CI, 0.64-0.8...
