The Analgesic Efficacy and Safety of Venlafaxine for Prevention of Postherpetic Neuralgia in Patients With Acute Herpes Zoster

Postherpetic neuralgia (PHN) is the most common complication of herpes zoster (HZ) and represents a major clinical challenge due to its chronicity and impact on quality of life. Current treatments for acute HZ pain have limited efficacy in preventing PHN, highlighting the need for effective preventive strategies targeting early pathophysiological mechanisms. Venlafaxine as a plausible and clinically relevant candidate for early intervention to prevent the transition from acute HZ pain to PHN.

The Analgesic Efficacy and Safety of Mirogabalin in Patients With Herpes Zoster

Herpes zoster (HZ) is characterized by a painful dermatomal rash and significantly affects quality of life, with acute pain increasing the risk of postherpetic neuralgia. Although early antiviral therapy limits viral replication, its analgesic effect is insufficient, and many patients experience inadequate relief despite stepwise use of non-opioids and opioids. Gabapentinoids such as gabapentin and pregabalin are recommended adjuncts, but their efficacy in acute HZ is inconsistent and often accompanied by adverse effects that limit tolerability. Mirogabalin, a newer gabapentinoid approved for peripheral neuropathic pain, has higher affinity and slower dissociation from the α2δ-1 subunit, suggesting stronger analgesia with fewer central side effects. However, its role in managing acute HZ pain remains unknown. We therefore hypothesize that adding mirogabalin to conventional therapy will provide superior pain relief compared with standard treatment alone, and propose a prospective, randomized, controlled, open-label, blinded-endpoint trial to evaluate this.

Safety and Immunogenicity of Recombinant Varicella Zoster Virus Vaccine in People With HIV Who Have a CD4 Count Less Than 300 or Greater Than or Equal to 300 and a Healthy Control Population

Background: Shingles is a painful, blistering rash caused by the same virus that causes chickenpox. Shingrix is a vaccine approved to prevent shingles in healthy adults over age 50 and in immunocompromised adults over age 18. Researchers want to learn more about how people with HIV respond to Shingrix. Objective: To learn how Shingrix affects the immune response in people with HIV. Eligibility: People aged 18 years and older with HIV. Healthy people aged 50 years or older are also needed. Design: Participants will have at least 4 clinic visits in 1 year. Participants will be screened. They will have a physical exam with blood and urine tests. At their first visit, participants will receive Shingrix as a shot in the upper arm. They will have a rectal swab; a cotton swab will be inserted into the rectum and rotated gently to collect bacteria. Participants will receive a second shot of Shingrix 2 months after the first one. They will visit the clinic again 3 and 12 months after the first shot. Participants will receive a 28-day memory tool. They will write down their symptoms between clinic visits. They will have up to 4 phone calls to talk about side effects of the shot. Participants may undergo apheresis: They will lie still while blood is drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in their other arm.

Electroacupuncture Regulation of Immune Cells in Herpes Zoster

Herpes Zoster (HZ), caused by the Varicella-Zoster Virus (VZV), is a common infection characterized by localized pain and blistering, with higher incidence in females. HZ affects patients' physical health, mental well-being, and quality of life. The immune system is critical in HZ pathogenesis. Studies show acupuncture relieves pain, modulates immunity, and may lower postherpetic neuralgia (PHN) risk. However, evidence is limited on whether electroacupuncture (EA) alleviates HZ by modulating immune cells. Using mass cytometry (CyTOF), this study will analyze peripheral immune cell changes pre- and post-EA to explore its regulatory effects on HZ immunity. This study will recruit HZ patients and healthy controls (HC), dividing patients into medication-only and medication+EA groups to assess EA's potential immunomodulatory effects in HZ treatment.

The Analgesic Efficacy and Safety of Baclofen in Patients With Herpes Zoster

Herpes zoster (HZ) is characterized by a painful dermatomal rash and significantly affects quality of life, with acute pain increasing the risk of postherpetic neuralgia. Although early antiviral therapy limits viral replication, its analgesic effect is insufficient, and many patients experience inadequate relief despite stepwise use of non-opioids and opioids. Recent attention has focused on the potential role of muscle relaxant, which can relieve skeletal muscle spasms and associated pain in acute musculoskeletal conditions. Therefore, investigators hypothesize that baclofen may effectively reduce the severity of HZ pain without significantly increasing adverse events.

The Analgesic Efficacy and Safety of Loxoprofen Sodium Patch in Patients With Herpes Zoster

Herpes zoster (HZ) is characterized by a painful dermatomal rash and significantly affects quality of life, with acute pain increasing the risk of postherpetic neuralgia. Although early antiviral therapy limits viral replication, its analgesic effect is insufficient, and many patients experience inadequate relief despite stepwise use of non-opioids and opioids. Topical NSAIDs offer a promising alternative by delivering localized analgesia with reduced systemic exposure. Therefore, investigators hypothesize that loxoprofen sodium patch may effectively reduce the severity of HZ pain without significantly increasing adverse events.

The Analgesic Efficacy and Safety of Flurbiprofen Patch in Patients With Herpes Zoster

Herpes zoster (HZ) is characterized by a painful dermatomal rash and significantly affects quality of life, with acute pain increasing the risk of postherpetic neuralgia. Although early antiviral therapy limits viral replication, its analgesic effect is insufficient, and many patients experience inadequate relief despite stepwise use of non-opioids and opioids. Topical NSAIDs offer a promising alternative by delivering localized analgesia with reduced systemic exposure. Therefore, investigators hypothesize that flurbiprofen patch may effectively reduce the severity of HZ pain without significantly increasing adverse events.

The Analgesic Efficacy and Safety of Tulodesvenlafaxine in Patients With Herpes Zoster

Herpes zoster (HZ) is characterized by a painful dermatomal rash and significantly affects quality of life, with acute pain increasing the risk of postherpetic neuralgia. Although early antiviral therapy limits viral replication, its analgesic effect is insufficient, and many patients experience inadequate relief despite stepwise use of non-opioids and opioids. Recent attention has focused on the potential role of antidepressants, which have central antinociceptive property and may offer analgesic benefits by modulating central nervous system pain pathways through increased serotonin and norepinephrine availability. Therefore, investigators hypothesize that tulodesvenlafaxine may effectively reduce the severity of HZ pain without significantly increasing adverse events.

Recent attention has focused on the potential role of antidepressants, which have central antinociceptive property and may offer analgesic benefits by modulating central nervous system pain pathways through increased serotonin and norepinephrine availability. Therefore, investigators hypothesize that desvenlafaxine may effectively reduce the severity of HZ pain without significantly increasing adverse events.

Immunogenicity and Safety of SYS6017 in the Participants Aged 40 Years and Above

Herpes zoster is caused by the reactivation of latent varicella-zoster virus (VZV) which stays in latency after its primary infection. Immunosenescence contributes significantly to elevating morbidity associated with aging. Vaccination plays a key role in reducing the disease burden of zoster and the associated complications. We are conducting a study entitled "A Randomized, Blinded, Placebo- and Active-Controlled, Adaptive Phase 2 Clinical Trial to Evaluate the Immunogenicity and Safety of SYS6017 (a Herpes Zoster mRNA Vaccine) in Healthy Participants Aged 40 Years and Above".

The Analgesic Efficacy and Safety of Crisugabalin in Patients With Herpes Zoster

Herpes zoster (HZ) is characterized by a painful dermatomal rash and significantly affects quality of life, with acute pain increasing the risk of postherpetic neuralgia. Although early antiviral therapy limits viral replication, its analgesic effect is insufficient, and many patients experience inadequate relief despite stepwise use of non-opioids and opioids. Gabapentinoids such as gabapentin and pregabalin are recommended adjuncts, but their efficacy in acute HZ is inconsistent and often accompanied by adverse effects that limit tolerability. Crisugabalin, a newer gabapentinoid approved for peripheral neuropathic pain, has higher affinity and slower dissociation from the α2δ-1 subunit, suggesting stronger analgesia with fewer central side effects. However, its role in managing acute HZ pain remains unknown. We therefore hypothesize that adding crisugabalin to conventional therapy will provide superior pain relief compared with standard treatment alone, and propose a prospective, randomized, controlled, open-label, blinded-endpoint trial to evaluate this.

The Immunogenicity and Safety of Zostavax® and Shingrix® in Rheumatoid Arthritis Patients Using Abatacept

This investigator-initiated study will serve as a sub-study for the American College of Rheumatology-sponsored VERVE protocol currently funded by the NIH. This double-blinded multicenter randomized pragmatic trial is designed to determine whether Zostavax or Shingrix are safe and effective in patients with rheumatoid arthritis (RA) currently using anti-tumor necrosis factor (TNF) therapies. Inclusion/exclusion criteria for this sub-study mirror that of the parent VERVE trial with the exception of abatacept therapy being allowed. Preliminary data from the VERVE parent protocol enrolling patients using anti-TNF therapy is encouraging in that few patients experienced adverse events (56 adverse events in 50 participants, out of 140 participants in total) and that 96.2% of these adverse events were considered either mild or moderate. Importantly, there have been no instances of vaccine dissemination or zoster events to date.
