Up to 97% of the transplant recipient children, who were submitted to CsA therapy, have been reported to suffer from this side-effect. Several conflicting theories have been proposed to explain the fibroblast's function in CsA-induced gingival overgrowth. Read More

    Laser-Assisted Periodontal Management of Drug-Induced Gingival Overgrowth under General Anesthesia: A Viable Option.
    Case Rep Dent 2013 29;2013:387453. Epub 2013 May 29.
    Department of Periodontics, Sri Sai College of Dental Surgery, Kothrepally, Vikarabad, Andhra Pradesh 501101, India.
    Gingival overgrowth/hyperplasia can be attributed to several causes, but drug-induced gingival overgrowth/hyperplasia arises secondarily to prolonged use of antihypertensive drugs, anticonvulsants and immunosuppressants. The management is complex in nature considering the multitude of factors involved such as substitution of drug strict plaque control along with excision of the tissue to be performed under local anesthesia as outpatient. In the recent times, the patient's psychological fear of the treatment with the use of surgical blade and multiple visits has developed the concept of single visit treatment under general anesthesia incorporating a laser as viable option.

    Calcium channel blocker-induced gingival enlargement.
    J Hum Hypertens 2014 Jan 6;28(1):10-4. Epub 2013 Jun 6.
    Department of Periodontology, College of Dentistry, University of Tennessee Health Science Center, Memphis, TN, USA.
    Despite the popularity and wide acceptance of the calcium channel blockers (CCBs) by the medical community, their oral impact is rarely recognized or discussed. CCBs, as a group, have been frequently implicated as an etiologic factor for a common oral condition seen among patients seeking dental care: drug-induced gingival enlargement or overgrowth. This enlargement can be localized or generalized, and can range from mild to extremely severe, affecting patient's appearance and function. Read More

    [Connective tissue growth factors, CTGF and Cyr61 in drug-induced gingival overgrowth--an animal model].
    Rev Med Chir Soc Med Nat Iasi 2008 Oct-Dec;112(4):1026-33
    Clinica de Chirurgie OMF, Facultatea de Medicină Dentară, Universitatea de Medicină si Farmacie Gr.T. Popa Iaşi.
    Human gingival overgrowth may occur as a side effect of chronic administration of some therapeutic agents. The mechanisms responsible for the gingival tissues lesions, fibrosis and inflamation, involve an impaired balance between the production and the degradation of type I collagen. It has been demonstrated that CCN2/CTGF, a connective tissue growth factor, is highly expressed in the gingival tissues and positively correlated with the degree of fibrosis in the drug-induced gingival overgrowth.

A 45 year-old Caucasian male patient with hypertension, who received amlodipine (10 mg/day, single dose orally) for two months, sought medical attention because of the new-onset gingival enlargement. On clinical examination a generalized and firm overgrowth of the gingival throughout the maxilla and the mandible were evident. Read More

    Drug-induced side effects affecting the gastrointestinal tract.
    Expert Opin Drug Saf 2006 Jul;5(4):585-92
    The University of New South Wales, Faculty of Medicine, Department of Gastroenterology and Hepatology, Bankstown-Lidcombe Hospital, Eldridge Road, Bankstown, NSW 2200, Sydney, Australia.
    With the ever-growing armamentarium of pharmacological agents, the gastrointestinal drug-induced side effects of dyspepsia, nausea, vomiting, diarrhoea and constipation are increasingly seen. They are often self-limiting and without serious sequelae, but of greater concern is drug-induced mucosal ulceration that can manifest as gastrointestinal haemorrhage, stricture and perforation. These complications are mainly attributable to NSAIDs and aspirin, which can injure the mucosa anywhere along the gastrointestinal tract. Read More

    [Adverse drug effects in the oral region].

    Seksjon for odontologisk farmakologi og farmakoterapi, Universitetet i Oslo, Postboks 1057 Blindern, 0316 Oslo.
    Syphilis was previously termed "the great imitator" because so many of the signs and symptoms are indistinguishable from those of other diseases. This role has been taken over by drugs, and this also applies to adverse drug reactions in the oral region. Accordingly, a careful drug history, including identification of any prescription, over-the-counter, or herbal medicines used, may give an important clue to the differential diagnosis of oral diseases when the aetiology is not apparent.

    Nephrol Dial Transplant 2005 Apr;20(4):735-42
    Mansoura Urology and Nephrology Center, Mansoura University, Egypt.
    Background: Although remission is achieved in most children with nephrotic syndrome by treatment with corticosteroids, a significant proportion of patients experience relapses. Continuous or repeated use of corticosteroids inevitably induces features of steroid side-effects. Cyclosporin (CsA) has been used in the treatment of idiopathic steroid-dependent and -resistant nephrotic syndrome. Read More

    Drug-induced fibrosis: interference with the intracellular collagen degradation pathway.
    Curr Opin Drug Discov Devel 2004 Sep;7(5):720-4
    University of Toronto, Toronto, Ontario M5S 3E2, Canada.
    Drug-induced fibrosis and overgrowth of the extracellular matrix are high prevalence lesions of the oral mucosa. Drugs, such as dilantin, cyclosporin A and nifedipine can cause the gum tissues to overgrow, thereby preventing normal mastication and promoting infection. The causes of these disorders are poorly understood but recent evidence suggests that a common pathway targeted by these three drugs is the regulation of the intracellular pathway of collagen degradation.

    The immunosuppressant and hyperplasia-inducing drug cyclosporin A regulates the cell cycle and cyclin B1 gene expression in gingival fibroblasts in vitro.
    Cell Tissue Res 2004 Aug 24;317(2):221-5. Epub 2004 Jun 24.
    Periodontology Unit, Eastman Dental Institute for Oral Health Care Sciences, University College London, 256 Grays Inn Road, London, UK.
    Gingival overgrowth is a frequent and adverse side-effect caused by certain immunosuppressant, anti-convulsant and calcium channel-blocking drugs. Although the precise mechanism is not yet known, the enhanced proliferation of gingival fibroblasts observed in this disease could be caused at least partly by the effects of the drugs on the cell cycle and cyclin expression in these cells. In the present study, flow cytometry analysis of the effects of the immunosuppressant drug cyclosporin A showed that it enhanced cell-cycle progression of gingival fibroblasts in vitro and also up-regulated the expression of cyclin B1.
