Nanomicellar Curcumin Supplementation Improves the Clinical Manifestations of HAM/TSP Patients.
Article in Advances in experimental medicine and biology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHTLV-1 infection causes a chronic, progressive, demyelinating, neuroinflammatory disease called HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Treatment of HAM/TSP patients which have high levels of proviral load and pro-inflammatory markers is a challenge for clinicians. Therefore, we aimed to investigate the immunomodulatory, anti-inflammatory, and antiviral effects of curcumin in HAM/TSP patients.
methodsIn this study, 20 newly diagnosed HAM/TSP patients (2 men and 18 women) were enrolled and evaluated for clinical symptoms, HTLV-1 proviral load, Tax and HBZ expression, neopterin serum concentration, and complete blood count (CBC) before and 12 weeks after treatment with nanomicellar curcumin (80 mg/day, orally).
resultsClinical symptoms such as the mean Osame Motor Disability Score and Ashworth Spasticity Scale Score were significantly improved after the treatment (P = 0.001 and P = 0.001). Sensory symptoms such as pain and paresthesia were significantly decreased in all of the patients (P = 0.001). Furthermore, urinary disorders, including urinary frequency, incontinence, and the feeling of incomplete bladder emptying, were significantly improved (P = 0.001, P = 0.003, and P = 0.03). However, the mean HTLV-1 proviral load (P = 0.97) and CBC were similar, whereas Tax, HBZ, and neopterin levels tend to increase after the treatment (P = 0.004, P = 0.08, and P = 0.04).
conclusionResults suggest that curcumin can safely improve the clinical symptoms of HAM/TSP patients but has no observable positive effects on the HTLV-1 proviral load, Tax, and HBZ expression. Therefore, prolonged use or the use of curcumin with antiviral agents in addition to clinical signs and symptoms can reduce the HTLV-1 proviral load and the expression of functional viral factors such as Tax and HBZ.
