Abstract: Dear Madam, Dengue fever is a rapidly spreading mosquito-borne viral infection that predominantly affects tropical and subtropical regions worldwide. It is estimated that over 390 million people globally are at risk of contracting dengue infection ¹. Moreover, the mode of transmission of dengue virus is primarily by the bite of infected female mosquitoes of Aedes aegypti. Dengue can manifest in a broad range of symptoms, from mild Dengue fever to more severe conditions like Dengue haemorrhagic syndrome (DHS), with Dengue shock syndrome (DSS) being the most critical form. Pakistan has recently experienced a surge in dengue cases, with the National Institute of Health reporting 79,007 in 2022—three times higher than the previous decade’s figures. Notably, Sindh leads with the greatest number of cases (32%) followed by Punjab including Islamabad (29%), Khyber Pakhtunkhwa (25%), and Balochistan (14%) ². Currently, there are no clinically approved antiviral treatments available for dengue infection. Management primarily focuses on supportive care, including the administration of acetaminophen to control fever, adequate hydration and rest to manage symptoms. Platelet transfusions are advised when platelet counts fall below critical thresholds. However, there is growing interest of researchers in exploring novel treatments to reduce the duration of DENV infection and improve patient outcomes. Recent studies have focused on exploring the potential impact of vitamin D supplementation in the management of dengue fever. Vitamin D is known to have an immunomodulatory effect on the body. Studies suggest that Vitamin D alters the immune response against the DENV and halts its RNA replication. and decreases the production of pro-inflammatory cytokines (such as TNF-a, IL-6, IL-1), and promotes the production of anti-inflammatory cytokines like IL-10. A study conducted in Colombia found that supplementing dengue patients with 4000 IU of vitamin D effectively suppressed viral replication and promoted an anti-inflammatory immune response³. ---Continue
