Int J Hematol 2024:10.1007/s12185-024-03825-w. [PMID: 39088188 DOI: 10.1007/s12185-024-03825-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 06/26/2024] [Accepted: 07/17/2024] [Indexed: 08/02/2024]
Abstract
Thalassemia is an inherited genetic disorder of hemoglobin that affects a large population worldwide, and it is estimated that between 50,000 and 60,000 infants with thalassemia are born each year. The most common treatment for thalassemia is blood transfusion, which leads to iron overload. This in itself is a serious clinical condition, and is commonly managed with iron chelation therapy. However, iron chelators can cause various skin complications, including hyperpigmentation, skin rash, itching, and photosensitivity. These skin side effects can impact patients' quality of life. Therefore, this article provides a comprehensive overview of skin complications caused by iron chelators, along with a proposed comprehensive approach to their management in patients with beta-thalassemia. Key strategies include patient education, regular skin assessment, sun protection measures, symptomatic relief with topical corticosteroids and antihistamines, and consideration of treatment modification if severe complications occur. Collaboration between hematologists and dermatologists, along with psychological support and regular follow-up, is an essential component of this multidisciplinary approach. By implementing these strategies, healthcare providers can optimize skin care for patients with beta-thalassemia treated with iron chelators and improve their quality of life.

Wan ZD, Li WZ. Repairing of recurrent leg ulcer induced by hydroxyurea with posterior tibial artery perforator propeller flap: Case report. Int J Surg Case Rep 2024; 114:109049. [PMID: 38029574 PMCID: PMC10698520 DOI: 10.1016/j.ijscr.2023.109049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 11/09/2023] [Accepted: 11/09/2023] [Indexed: 12/01/2023] Open
Abstract
INTRODUCTION AND IMPORTANCE Hydroxyurea is a cytotoxic drug commonly used to treat various myeloproliferative disorders. However, prolonged oral administration of this drug may trigger skin side effects and ulcers. There are few clinical reports on treating leg ulcers caused by hydroxyurea and even fewer clinical reports on managing recurrent ulcers after treatment. CASE PRESENTATION An 87-year-old woman with essential thrombocythemia presented with a painful skin ulcer on her left calf. After failed outpatient treatment, she opted for hospitalisation for free skin grafting. Four months later, ulcers reappeared at the transplant site, leading to her readmission to the hospital. The diagnosis revealed that the leg ulcers were caused by hydroxyurea. Despite this, she persisted with hydroxyurea treatment and subsequently underwent posterior tibial artery perforator flap surgery. During the two-year follow-up, a new ulcer developed on the medial condyle of her other calf. However, no new ulcers or local pain were observed in the area where perforator flap grafting was performed. CLINICAL DISCUSSION Leg ulcers caused by hydroxyurea are rare clinically and can easily be misdiagnosed. There is currently minimal research on ulcer recurrence after treatment. Posterior tibial perforator flaps may more effectively promote the healing of recurrent ulcers. CONCLUSION Compared to conservative treatment and skin grafting surgery, the posterior tibial artery perforator flap offers a dependable blood supply and enhances the likelihood of wound healing. It can be considered an option, particularly for recurrent and refractory ulcers, even without discontinuing medication.

Abstract
Introduction: Hydroxyurea (HU) is an S-phase specific oral chemotherapeutic agent that inhibits ribonucleotide diphosphate reductase. It is the most common used cytoreductive drug in patients (pts) with BCR-ABL1 negative myeloproliferative neoplasms (MPN) and sickle cell disease (SCD). The World Health Organization lists HU as an "essential drug". Although most patients tolerate HU well, cutaneous adverse events (CAE) are frequent side effects and may limit its long-term use. This has become increasingly evident in recent years, especially in MPN patients, where CAE were previously underestimated and underdiagnosed.Areas covered: In this review, we present the available literature on HU-related CAE in MPN patients. In particular, data from a recently published and so far, only prospective non-interventional study investigating CAE in 172 MPN patients will be discussed in detail and compared with previously available data. Finally, we give an overview of the management of HU-related CAE in MPN patients and provide recommendations on the practical clinical approach.Expert opinion: In clinical practice, HU associated CAE are common and have important diagnostic and therapeutic consequences. Therefore, they should be considered in all MPN patients treated with HU in the future.

Abstract
Hydroxyurea (HU) is known to cause a broad spectrum of cutaneous side effects, ranging from relatively benign to severe. Although dermatologists are often consulted for the treatment of these side effects, a comprehensive resource discussing the different types and their management is lacking. In this study, we conducted a literature search in order to critically evaluate the reported types and management of hydroxyurea's cutaneous side effects, as well as review its mechanism of action, dermatologic uses, and common systemic side effects. Relatively common and benign side effects include hyperpigmentation, xerosis, and skin atrophy. While serious cutaneous side effects such as leg ulcers or nonmelanoma skin cancers occur in a substantial proportion of patients, these may resolve with HU discontinuation and proper dermatologic management. Therefore, it is crucial for dermatologists to be aware of these various cutaneous side effects and their management as prompt diagnosis and proper treatment will improve patient outcomes.

Abstract
Since myeloproliferative neoplasms (MPN) pose a significant risk for vascular and thrombotic complications, cytoreductive therapies, such as hydroxyurea (HU), interferon (IFN) inhibitors, and Janus kinase (JAK) inhibitors are recommended for patients at high risk. However, these agents also place patients at increased risk for drug-related cutaneous adverse events. Herein, we review the literature on skin toxicity related to the use of drugs for the treatment of MPN. Overall, the cytoreductive agents used for MPN are generally well tolerated and considered to be safe, except IFN, for which dropout rates as high as 25% have been reported. While IFN is known to give rise to flu syndrome, it rarely leads to hematological alterations. The most common hematological side effects of HU are mild and include granulocytopenia, anemia, and thrombocytopenia. The JAK inhibitor ruxolitinib has been associated with cytopenia and a higher incidence of viral infections, as well as increased risk for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Based on the present analysis, it can be concluded that cutaneous toxicity is not a negligible complication of commonly used treatments for MPN. While further research is needed, patients on these agents, and especially those with a history of cutaneous malignancies, should undergo thorough skin examination before and during therapy. In addition, detailed history is critical since many patients who develop non-melanoma skin cancer have multiple preexisting risk factors for cutaneous carcinogenesis.

Abstract
Background While skin carcinomas are reported in chronic ulcers and in patients treated with hydroxyurea (HU) for myeloproliferative neoplasms, no skin carcinoma has been reported in patients with sickle cell disease (SCD), presenting chronic skin ulcers or treated with HU. The objective was to estimate the risk of cutaneous malignant transformation in SCD patients with prolonged leg ulcers or under HU therapy. Results In this cross-sectional study, the cohort consisted of 1543 patients. In the first series, 29 patients presented a total of 53 ulcers lasting more than two years. The median age was 35 ± 8.4 years old. The median duration for a single ulcer was 9.2 ± 7 years. None of the examined ulcers showed any suspicious area of malignant transformation. In the second series, 187 patients treated with HU for more than two years were identified. The median age was 31.3 ± 9.9 years old. The median duration of treatment with HU was 6 ± 3.2 years. No skin carcinoma or actinic keratosis was recorded. Conclusions This study showed that skin carcinogenesis did not occur in our series of SCD patients exposed to transforming events such as long term HU treatment or prolonged leg ulcers.

Abstract
Objective. The randomized controlled trial was to evaluate the efficacy of topical Chinese herbal Zhangpi Ointment for hydroxyurea-induced leg ulcers in patients with myeloproliferative neoplasms. Patients and Methods. This single-center, prospective, randomized, open-label, controlled clinical trial conducted at Shanghai Ninth People's Hospital enrolled 54 patients with hydroxyurea-induced leg ulcers. Patients were randomly assigned to the control group (n = 27) treated with chlorhexidine dressing or the intervention group (n = 27) treated with the Zhangpi Ointment. Finally, 26 patients in the control group and 23 patients in the intervention group completed 8 weeks of observation. Results. The rate of complete healing was 100% for the intervention group, which was significantly higher than that of the control group (96.15%) (P<0.05). Furthermore, the intervention group achieved a significantly higher rate of wound healing (95.56%) than the control group (69.02%) at week 4 (P<0.01). The intervention group took 34 ± 5 days to achieve complete healing while the control group took 41 ± 7 days (P < 0.01). Moreover, grade 3/4 side effects were observed in neither group. Conclusion. The Zhangpi Ointment is effective in promoting the healing of hydroxyurea-induced leg ulcers in patients with myeloproliferative neoplasms, providing a therapeutic option for a condition that is recalcitrant to conventional therapy.

Abstract
BACKGROUND Hydroxyurea (HU) is an antimetabolite agent that interferes with the S-phase of cellular replication and inhibits DNA synthesis, with little or no effect on RNA or protein synthesis. It is used in the treatment of many myeloproliferative disorders (MD) and is particularly a first line treatment drug for intermediate to high-risk essential thrombocythemia. Although safe and very well tolerated by the patients suffering from MD, there have been numerous reports of a broad palette of cutaneous side effects associated with prolonged intake of the medication. These may include classical symptoms such as xerosis, diffuse hyperpigmentation, brown-nail discolouration, stomatitis and scaling of the face, hands, and feet or more serious side effects such as actinic keratosis lesions, leg ulcers and multiple skin carcinomas. CASE REPORT We report a case of a 52-year-old man, on long-term therapy with HU for essential thrombocytosis, with several concurrent skin lesions. Despite the perennial use of HU, the cutaneous changes were neglected. The local dermatological examination revealed oval perimalleolar ulcer on the right leg, with dimensions 6 x 4 cm, clearly demarcated from the surroundings with regular margins, periulcerous erythema, with very deep and highly fibrinous bed of the ulcer, positive for bacterial infection. The ulcer was treated with topical wound therapy with alginate and parenteral antibiotics. The extended dermatological screening also showed two nummular lesions in the right brachial region, presenting as erythematous papules with sharp margins from the surrounding skin, gritty desquamation and dotted hyperpigmentations inside the lesion. Further dermoscopy and biopsy investigations confirmed a diagnosis of basal cell carcinoma. Nasal actinic keratosis was also noted. The patient was advised for discontinuing or substituting the HU therapy. CONCLUSION We present this case to draw attention to the various cutaneous side effects that occur with perennial HU use and suggest an obligatory reference to a dermatological consult.

Abstract
A 59-year-old African American female presented to a plastic surgery office in consultation for a very painful non-healing wound of her right lateral malleolus. An incisional biopsy was performed and ultimately a diagnosis of hydroxyurea-induced ulcer was concluded. Descriptions of this entity are rare in the surgical and wound care professional literature. This diagnosis does appear in the hematology/oncology literature; however, these practitioners may not be the first to examine a patient with the development of such an ulcer. This article presents the pathophysiology and clinical presentation of hydroxyurea-induced ulceration as well as the characteristics of hydroxyurea-induced ulceration in addition to the case study.
